Vallum
–
Vallum is either the whole or a portion of the fortifications of a Roman camp. The vallum usually comprised an earthen or turf rampart with a palisade on top. The name is derived from vallus, and properly means the palisade which ran along the edge of the top of the agger. Hence the Greek vallus could easily be taken hold of by its branches and pulled from its place. The Roman vallus, on the contrary, presented no convenient handle, required very great force to pull it down, the Greek valli were cut on the spot, the Romans prepared theirs beforehand. They were made of any strong wood, but oak was preferred, while on the march, each soldier carried three or four strong wooden stakes each at least 1.5 m long and pointed at both ends. A number of these have found in excavations, sufficiently well-preserved to show that they were waisted. One suggestion is that the waist facilitated them being tied together loosely in threes to form a kind of caltrop or Czech hedgehog that could be placed on the rampart of the vallum. It is likely that these would be augmented with whatever was to hand, such a circumvallation, besides cutting off all communication between the town and the surrounding country, formed a defence against the sallies of the besieged. There was often a line of fortifications, the inner against the town. In this case the army was encamped between the two lines of works and this kind of circumvallation, which the Greeks called ἀποτειχισμός and περιτειχισμός, was employed by the Peloponnesians in the siege of Plataea. Their lines consisted of two walls at the distance of 16 feet, which surrounded the city in the form of a circle, between the walls were the huts of the besiegers. The walls had battlements, and at every ten battlements was a tower, there was a passage for the besiegers through the middle of each tower. On the outside of each wall was a ditch, the towers in such lines were similar to those used in attacking fortified places, but not so high, and of course not moveable. The vallum-building technique was taken by neighbouring people, such as the Byzantines. Examples of valla include, The Vallum, a component of Hadrians Wall Trajans Wall Athanarics Wall ^ Latin vallus derives from Proto-Indo-European *walso-, vallus is the source of English wall. The word vallus is sometimes used as equivalent to vallum, a Dictionary of Greek and Roman Antiquities. Albemarle Street, London, John Murray,1890

Magna Carta
–
Magna Carta Libertatum, commonly called Magna Carta, is a charter agreed to by King John of England at Runnymede, near Windsor, on 15 June 1215. Neither side stood behind their commitments, and the charter was annulled by Pope Innocent III, at the end of the 16th century there was an upsurge in interest in Magna Carta. Lawyers and historians at the believed that there was an ancient English constitution, going back to the days of the Anglo-Saxons. Both James I and his son Charles I attempted to suppress the discussion of Magna Carta, until the issue was curtailed by the English Civil War of the 1640s and the execution of Charles. The political myth of Magna Carta and its protection of ancient personal liberties persisted after the Glorious Revolution of 1688 until well into the 19th century. In the 21st century, four exemplifications of the original 1215 charter remain in existence, held by the British Library, there are also a handful of the subsequent charters in public and private ownership, including copies of the 1297 charter in both the United States and Australia. The original charters were written on parchment sheets using quill pens, in heavily abbreviated medieval Latin, each was sealed with the royal great seal, very few of the seals have survived. The four original 1215 charters were displayed together at the British Library for one day,3 February 2015, to mark the 800th anniversary of Magna Carta. Magna Carta originated as an attempt to achieve peace between royalist and rebel factions in 1215, as part of the events leading to the outbreak of the First Barons War. England was ruled by King John, the third of the Angevin kings, although the kingdom had a robust administrative system, the nature of government under the Angevin monarchs was ill-defined and uncertain. Following the defeat of his allies at the Battle of Bouvines, John had to sue for peace, John was already personally unpopular with many of the barons, many of whom owed money to the Crown, and little trust existed between the two sides. John held a council in London in January 1215 to discuss potential reforms, both sides appealed to Pope Innocent III for assistance in the dispute. John also began recruiting mercenary forces from France, although some were sent back to avoid giving the impression that the King was escalating the conflict. Letters backing John arrived from the Pope in April, but by then the rebel barons had organised into a military faction and they congregated at Northampton in May and renounced their feudal ties to John, marching on London, Lincoln, and Exeter. Johns efforts to moderate and conciliatory had been largely successful. The King offered to submit the problem to a committee of arbitration with the Pope as the supreme arbiter, John met the rebel leaders at Runnymede, a water-meadow on the south bank of the River Thames, on 10 June 1215. Here the rebels presented John with their demands for reform. By 15 June, general agreement had been made on a text, and on 19 June and it focused on the rights of free men—in particular the barons

British Library
–
The British Library is the national library of the United Kingdom and the second largest library in the world by number of items catalogued. It holds well over 150 million items from many countries, as a legal deposit library, the British Library receives copies of all books produced in the United Kingdom and Ireland, including a significant proportion of overseas titles distributed in the UK. The Library is a public body sponsored by the Department for Culture, Media. The Librarys collections include around 14 million books, along with holdings of manuscripts. In addition to receiving a copy of every publication produced in the UK and Ireland, the Library adds some three million items every year occupying 9.6 kilometres of new shelf space. Prior to 1973, the Library was part of the British Museum, the Euston Road building is classified as a Grade I listed building, of exceptional interest for its architecture and history. The British Library was created on 1 July 1973 as a result of the British Library Act 1972. Prior to this, the library was part of the British Museum. In 1983, the Library absorbed the National Sound Archive, which holds many sound and video recordings, with over a million discs, the core of the Librarys historical collections is based on a series of donations and acquisitions from the 18th century, known as the foundation collections. From 1997 to 2009 the main collection was housed in this new building. Construction work on the Newspaper Storage Building was completed in 2013, the collection has now been split between the St Pancras and Boston Spa sites. The British Library Document Supply Service and the Librarys Document Supply Collection is based on the site in Boston Spa. Collections housed in Yorkshire, comprising low-use material and the newspaper and Document Supply collections, the Library previously had a book storage depot in Woolwich, south-east London, which is no longer in use. The new library was designed specially for the purpose by the architect Colin St John Wilson, facing Euston Road is a large piazza that includes pieces of public art, such as large sculptures by Eduardo Paolozzi and Antony Gormley. It is the largest public building constructed in the United Kingdom in the 20th century, in December 2009 a new storage building at Boston Spa was opened by Rosie Winterton. The building was Grade I listed on 1 August 2015, in England, Legal Deposit can be traced back to at least 1610. The other five libraries are, the Bodleian Library at Oxford, the University Library at Cambridge, the Trinity College Library at Dublin, in 2003 the Ipswich MP Chris Mole introduced a Private Members Bill which became the Legal Deposit Libraries Act 2003. The Act extends United Kingdom legal deposit requirements to electronic documents, such as CD-ROMs, the Library also holds the Asia, Pacific and Africa Collections which include the India Office Records and materials in the languages of Asia and of north and north-east Africa

Deed
–
For the British cargo ship, see SS Deed. For the reality series, see The Deed. A deed is any instrument in writing which passes, affirms or confirms an interest, right, or property and that is signed, attested, delivered. It is commonly associated with transferring title to property, the deed has a greater presumption of validity and is less rebuttable than an instrument signed by the party to the deed. A deed can be unilateral or bilateral, deeds include conveyances, commissions, licenses, patents, diplomas, and conditionally powers of attorney if executed as deeds. The deed is the descendant of the medieval charter. The traditional phrase signed, sealed and delivered refers to the practice of seals, however, agreements under seal are also called contracts by deed or specialty, in the United States, a specialty is enforceable without consideration. Specialties, as a form of contract, are bilateral and can therefore be distinguished from covenants, which, being also under seal, are unilateral promises. At common law, to be valid and enforceable, a deed must fulfill several requirements, It must state on its face that it is a deed and it must indicate that the instrument itself conveys some privilege or thing to someone. The grantor must have the ability to grant the thing or privilege. It must be executed by the grantor in presence of the number of witnesses. In some jurisdictions, a seal must be affixed to it, originally, affixing seals made persons parties to the deed and signatures optional, but seals are now outdated in most jurisdictions, so the signatures of the grantor and witnesses are primary. It must be delivered to and accepted by the grantee, conditions attached to the acceptance of a deed are known as covenants. A deed indented or indenture is one executed in two or more according to the number of parties, which were formerly separated by cutting in a curved or indented line known as the chirograph. A deed poll is one executed in one part, by one party, having the edge polled or cut even, in the transfer of real estate, a deed conveys ownership from the old owner to the new owner, and can include various warranties. The precise name and nature of these differ by jurisdiction. Often, however, the differences between them is the degree to which the grantor warrants the title. The grantor may give a general warranty of title against any claims, the latter type of deed is usually known as a special warranty deed

Seal (emblem)
–
A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, a wrapper for one such as a modern envelope, the seal-making device is also referred to as the seal matrix or die, the imprint it creates as the seal impression. In most traditional forms of dry seal the design on the matrix is in intaglio. The design on the impression will reverse that of the matrix and this will not be the case if paper is embossed from behind, where the matrix and impression read the same way, and both matrix and impression are in relief. However engraved gems were carved in relief, called cameo in this context. The process is essentially that of a mould and these pendent seal impressions dangled below the documents they authenticated, to which the attachment tag was sewn or otherwise attached. Some jurisdictions consider rubber stamps or specified signature-accompanying words such as seal or L. S. to be the equivalent of, i. e. an equally effective substitute for. In Europe, although coats of arms and heraldic badges may well feature in such contexts as well as on seals, the study of seals is known as sigillography or sphragistics. Seals were used in the earliest civilizations and are of importance in archaeology. In ancient Mesopotamia carved or engraved cylinder seals in stone or other materials were used and these could be rolled along to create an impression on clay, and used as labels on consignments of trade goods, or for other purposes. They are normally hollow and it is presumed that they were worn on a string or chain round the neck, many have only images, often very finely carved, with no writing, while others have both. From Ancient Egypt seals in the form of signet-rings, including some with the names of kings, have been found, recently, seals have come to light in South Arabia datable to the Himyarite age. One example shows a name written in Aramaic engraved in reverse so as to read correctly in the impression, from the beginning of the 3rd millennium BC until the Middle Ages, seals of various kinds were in production in the Aegean islands and mainland Greece. In the Early Minoan age these were formed of stone and ivory. By the Middle Minoan age a new set for seal forms, motifs, hard stone requires new rotary carving techniques. The Late Bronze Age is the par excellence of the lens-shaped seal and the seal ring. These were a luxury art form and became keenly collected. His collection fell as booty to Pompey the Great, who deposited it in a temple in Rome, engraved gems continued to be produced and collected until the 19th century

Latin
–
Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

Old French
–
Old French was the Gallo-Romance dialect continuum spoken from the 9th century to the 14th century. In the 14th century, these came to be collectively known as the langues doïl. The mid-14th century is taken as the period to Middle French. The areal of Old French in contemporary terms corresponded to the parts of the Kingdom of France, Upper Burgundy. As part of the emerging Gallo-Romance dialect continuum, the langues doïl were contrasted with the langue doc, in these examples, we notice a clear consequence of bilingualism, that sometimes even changed the first syllable of the Latin words. Pope estimated that perhaps still 15% of the vocabulary of modern French derives from Germanic sources, at the third Council of Tours in 813, priests were ordered to preach in the vernacular language, since the common people could no longer understand formal Latin. The second-oldest document in Old French is the Eulalia sequence, which is important for reconstruction of Old French pronunciation due to its consistent spelling. The Capetians langue doïl, the forerunner of modern standard French, did not begin to become the common speech of all of France, however, until after the French Revolution. In the Late Middle Ages, the Old French dialects diverged into a number of distinct langues doïl, during the Early Modern period, French now becomes established as the official language of the Kingdom of France throughout the realm, also including the langue doc-speaking territories in the south. Old French gives way to Middle French in the mid-14th century, the earliest extant French literary texts date from the ninth century, but very few texts before the 11th century have survived. The first literary works written in Old French were saints lives, the Canticle of Saint Eulalie, written in the second half of the 9th century, is generally accepted as the first such text. The first of these is the area of the chansons de geste. More than one hundred chansons de geste have survived in three hundred manuscripts. The oldest and most celebrated of the chansons de geste is The Song of Roland, a fourth grouping, not listed by Bertrand, is the Crusade cycle, dealing with the First Crusade and its immediate aftermath. Jean Bodels other two categories—the Matter of Rome and the Matter of Britain—concern the French romance or roman, around a hundred verse romances survive from the period 1150–1220. From around 1200 on, the tendency was increasingly to write the romances in prose, the most important romance of the 13th century is the Romance of the Rose which breaks considerably from the conventions of the chivalric adventure story. The Occitan or Provençal poets were called troubadours, from the word trobar to find, lyric poets in Old French are called trouvères. By the late 13th century, the tradition in France had begun to develop in ways that differed significantly from the troubadour poets

Parchment
–
Parchment is a writing material made from specially prepared untanned skins of animals—primarily sheep, calves, and goats. It has been used as a medium for over two millennia. Vellum is a finer quality parchment made from the skins of kids, lambs and it may be called animal membrane by libraries and museums that wish to avoid distinguishing between parchment and the more restricted term vellum. Today the term parchment is often used in non-technical contexts to refer to any animal skin, particularly goat, sheep or cow, that has been scraped or dried under tension. Vellum in theory refers exclusively to calfskin, and is used to denote a quality of material. The term parchment originally referred only to the skin of sheep and, occasionally, the word parchment evolved from the name of the city of Pergamon which was a thriving center of parchment production during the Hellenistic period. This account, originated in the writings of Pliny the Elder, is dubious because parchment had been in use in Anatolia, in the 2nd century BC a great library was set up in Pergamon that rivaled the famous Library of Alexandria. Writing on prepared animal skins had a history, however. H. Ibscher, and preserved in the Cairo Museum, a roll of the Twelfth Dynasty now in Berlin, the text now in the British Museum. Though the Assyrians and the Babylonians impressed their cuneiform on clay tablets, early Islamic texts are also found on parchment. In the later Middle Ages, especially the 15th century, parchment was largely replaced by paper for most uses except luxury manuscripts, new techniques in paper milling allowed it to be much cheaper than parchment, it was still made of textile rags and of very high quality. With the advent of printing in the fifteenth century, the demands of printers far exceeded the supply of animal skins for parchment. Although most copies of the Gutenberg Bible are on paper, some were printed on parchment,12 of the 48 surviving copies, in 1490, Johannes Trithemius preferred the older methods, because handwriting placed on parchment will be able to endure a thousand years. But how long will printing last, which is dependent on paper and it lasts for two hundred years that is a long time. In fact high quality paper from this period has survived 500 years or more very well, the heyday of parchment use was during the medieval period, but there has been a growing revival of its use among artists since the late 20th century. Although parchment never stopped being used it had ceased to be a choice for artists supports by the end of 15th century Renaissance. This was partly due to its expense and partly due to its working properties. When the water in paint media touches parchments surface, the collagen melts slightly, forming a bed for the paint

Codex
–
A codex is a book constructed of a number of sheets of paper, vellum, papyrus, or similar materials, with hand-written contents. The book is bound by stacking the pages and fixing one edge. Some codices are continuously folded like a concertina, the alternative to paged codex format for a long document is the continuous scroll. Examples of folded codices include the Maya codices, sometimes people use the term for a book-style format, including modern printed books but excluding folded books. The Romans developed the form from wooden writing tablets, the codexs gradual replacement of the scroll—the dominant book form in the ancient world—has been called the most important advance in book making before the invention of printing. The codex transformed the shape of the book itself, and offered a form that lasted for centuries, the spread of the codex is often associated with the rise of Christianity, which adopted the format for use with the Bible early on. In fact, any combination of codices and scrolls with papyrus and parchment is technically feasible, the codex began to replace the scroll almost as soon as it was invented. In Egypt, by the century, the codex outnumbered the scroll by ten to one based on surviving examples. By the sixth century, the scroll had almost vanished as a medium for literature, technically, even modern paperbacks are codices, but publishers and scholars reserve the term for manuscript books produced from Late antiquity until the Middle Ages. The scholarly study of manuscripts from the point of view of the bookbinding craft is called codicology. The study of ancient documents in general is called paleography, the Romans used precursors made of reusable wax-covered tablets of wood for taking notes and other informal writings. Two ancient polyptychs, a pentatych and octotych, excavated at Herculaneum used a connecting system that presages later sewing on of thongs or cords. Julius Caesar may have been the first Roman to reduce scrolls to pages in the form of a note-book. At the turn of the 1st century AD, a kind of folded parchment notebook called pugillares membranei in Latin became commonly used for writing in the Roman Empire, theodore Cressy Skeat theorized that this form of notebook was invented in Rome and then spread rapidly to the Near East. Codices are described in works by the Classical Latin poet. He wrote a series of five couplets meant to accompany gifts of literature that Romans exchanged during the festival of Saturnalia. ”Early codices of parchment or papyrus appear to have widely used as personal notebooks. The parchment notebook pages were commonly washed or scraped for re-use and consequently, writings in a codex were often considered informal, as early as the early 2nd century, there is evidence that a codex—usually of papyrus—was the preferred format among Christians. In the library of the Villa of the Papyri, Herculaneum, however, in the Nag Hammadi library, hidden about AD390, all texts are codices

Pumice
–
Pumice, called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker walls and being dark colored. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano, the unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility of gases that are dissolved in the lava, the simultaneous cooling and depressurization freezes the bubbles in a matrix. Eruptions under water are cooled and the large volume of pumice created can be a shipping hazard for cargo ships. Pumice is composed of highly microvesicular glass pyroclastic with very thin and it is commonly, but not exclusively of silicic or felsic to intermediate in composition, but basaltic and other compositions are known. Pumice is commonly pale in color, ranging from white, cream, blue or grey and it forms when volcanic gases exsolving from viscous magma form bubbles that remain within the viscous magma as it cools to glass. Pumice is a product of explosive eruptions and commonly forms zones in upper parts of silicic lavas. Pumice has a porosity of 90%, and initially floats on water. Scoria differs from pumice in being denser, with larger vesicles and thicker vesicle walls, it sinks rapidly. The difference is the result of the viscosity of the magma that forms scoria. When larger amounts of gas are present, the result is a variety of pumice known as pumicite. Pumice is considered a glass because it has no crystal structure, pumice varies in density according to the thickness of the solid material between the bubbles, many samples float in water. After the explosion of Krakatoa, rafts of pumice drifted through the Pacific Ocean for up to 20 years, in fact, pumice rafts disperse and support several marine species. In 1979,1984 and 2006, underwater volcanic eruptions near Tonga created large pumice rafts, there are two main forms of vesicles. Most pumice contains tubular microvesicles that can impart a silky or fibrous fabric, the elongation of the microvesicles occurs due to ductile elongation in the volcanic conduit or, in the case of pumiceous lavas, during flow. The other form of vesicles are subspherical to spherical and result from high pressure during eruption. Pumice is widely used to make concrete or insulative low-density cinder blocks

Blueprint
–
A blueprint is a reproduction of a technical drawing, documenting an architecture or an engineering design, using a contact print process on light-sensitive sheets. Introduced in the 19th century, the process allowed rapid and accurate reproduction of documents used in construction, the blue-print process was characterized by light-colored lines on a blue background, a negative of the original. The process was unable to color or shades of grey. Various base materials have been used for blueprints, paper was a common choice, for more durable prints linen was sometimes used, but with time, the linen prints would shrink slightly. To combat this problem, printing on imitation vellum and, later, polyester film was implemented, the process has been largely displaced by the diazo whiteprint process and by large-format xerographic photocopiers, so reproduced drawings are usually called prints or just drawings. The term blueprint is also used formally to refer to any floor plan. In 1861, Alphonse Louis Poitevin, a French chemist, found that ferro-gallate in gum is light sensitive, light turns this to an insoluble permanent blue. A coating of this chemical on a paper or other base may be used to reproduce an image from a translucent document, the ferro-gallate is coated onto a paper from aqueous solution and dried. In darkness, it is stable for up to three days and it is clamped under glass and a light transmitting document in a daylight exposure frame which is similar to a picture frame. The frame is put out into daylight requiring a minute or two under a sun or about ten times this under an overcast sky. Where ultra-violet light is transmitted the coating converts to a blue or black dye. The image can be seen forming, when a strong image is seen the frame is brought indoors and the unconverted coating, under the original image, is washed away. The result is a copy of the image with the clear background area rendered dark blue. The contact printing process has the advantage that no optical system is required. A further advantage is that the document will have the same scale as the original. Since the paper is soaked in liquid during processing, a change of scale can occur. Engineering drawings often are marked to remind users not to rely on the scale of reproductions, other blueprint processes based on photosensitive ferric compounds have been used. The best known is probably a process using ammonium ferric citrate, in this procedure, a distinctly blue compound is formed and the process is also known as cyanotype

Calfskin
–
Calfskin or calf leather is a leather or membrane produced from the hide of a calf, or juvenile domestic cattle. Calfskin is particularly valuable because of its softness, and fine grain and it is commonly used for high-quality clothing, shoes, wallets and similar products, as well as traditional leather bookbindings. In these contexts, just calf is commonly used, fine calfskin is one of the skins used for vellum and parchment manuscripts. In Spanish, the word is novillo, referring to leather from animals less than three years old, chickenskin, despite its name, is a form of calfskin made using the skin of unborn calves. In fashion, soft finished calfskin is sometimes described as veau velours, goldbeaters skin, made from the intestine of a calf Sheepskin

Sheepskin is the hide of a sheep, sometimes also called lambskin. Unlike common leather, sheepskin is tanned with the fleece intact, sheepskin numnahs, saddle pads, saddle seat covers, sheepskin horse boots, tack linings and girth tubes are also made and used in equestrianism. The fleece of sheepskin has excellent insulating properties and it is resistant to flame. Wool is considered by the profession to be hypoallergenic. Sheepskin is an insulator, and draws perspiration away from the wearer. There, it traps between 30 and 36 percent of its own weight in moisture, sheepskin coats, vests, and boots are common in the traditional dress of peoples throughout the Old World. In Ukraine a sheepskin coat is called a kozhukh and a vest a kozhushanka are a part of the national costume. In Spain such a coat is called a zamarra, in Tibet a chuba, in Kazakh a ton, in the English-speaking world, one may speak of a shearling coat. During the 1970s in Britain the suedehead subculture adopted this item as an identifying fashion, sheepskin-lined Ugg boots became popular worldwide in the late 1990s. The use of seat covers in moving vehicles dates back centuries, perhaps as long ago as the Bronze Age. The more sophisticated, tailor-made sheepskin car seat covers of the era have been popular in Europe for decades. The quality of the used in each application depends on several factors, mostly whether the pelt. Where the pelt is visible, better quality hide with minimal seed will be used, Seed contamination is where patches of scar tissue remain, resulting from a healed seed burrow wound during the animals life. This scar tissue can fall out leaving small holes after the pelt is processed or it can remain in place leaving imperfections in the pelt which cannot be corrected, Seed contamination is graded as follows, No Visible Seed - Visually free of seed contamination. This does not however mean the skin is completely free of seed, Light Seed - Slight seed contamination visible in the wool but minimal mainly concentrated in the belly regions. Medium Seed - Light seed contamination is present over most of the surface but is concentrated around the belly area. Heavy Seed - Heavy contamination extending through the majority of the wool but especially prevalent around the belly area, burry - Wool contaminated with hard seed. Can vary from light to heavy concentration and this level of seed can cause problems if it is not removed before fleshing starts as the rollers can sometimes punch them through the skin

Kidskin

Kidskin or kid leather is a type of soft, thin leather that is traditionally used for gloves. It is widely used for fashion purposes such as footwear. Kidskin is traditionally made from goatskin - more specifically, the skin of young goats, kid leather is, and has been used for a number of purposes other than gloves and footwear. Early flexible hair rollers were made from kidskin, giving a very tight curl. While vellum is made using calfskin, kidskin can also be used. David Laurent de Lara, describing himself as illuminating artist to Queen Victoria, a form of early medieval parchment, called carta lustra, acting as tracing paper was made using kidskin. Kid was particularly used in doll-making during the nineteenth and early twentieth century as a popular material for both French and German doll bodies, particularly fashion dolls. Kid-leather is often used in the construction of instruments such as the bag of the tsampouna. It was also an option for such as those on tambourines. The Dalén light, used in lighthouses, uses a paraffin-wax saturated kidskin diaphragm in its construction, in 1916 it was noted that there were over sixty types of goatskin, distinguished by the tanning and finishing processes used. Some of these types are, Bronze kid - Cochineal-dyed for a bronzed finish, cadet kid Cheveril - A very flexible kid leather used in the late 16th and early 17th centuries. Diphera - Mid-19th century type of fine kid used for bonnets, dongola - Skin from the sheep, kangaroo or goat. French kid - A high quality kidskin, glacé kid - Extremely glossy, shiny finish, often made in more readily available sheepskin, although true kidskin makes better quality glacé kid. Gold kid - Kidskin gilded for a metallic finish, kangaroo kid - Kidskin finished to emulate kangaroo leather. Mat kid - Beeswax and olive-oil treated kidskin with a dull, morocco Patent kid - japanned leather. Pebbled Royal kid Suede kid - Kidskin with a suede finish, vici kid - A trademark for high quality chrome-tanned kidskin with a soap and oil finish, developed by Robert Foederer in Philadelphia in the mid-1880s

Portolan chart
–
Portolan or portulan charts are navigational maps based on compass directions and estimated distances observed by the pilots at sea. They were first made in the 13th century in Italy, and later in Spain and Portugal, with the advent of widespread competition among seagoing nations during the Age of Discovery, Portugal and Spain considered such maps to be state secrets. The English and Dutch relative newcomers found the description of Atlantic and Indian coastlines extremely valuable for their raiding, the word portolan comes from the Italian adjective portolano, meaning related to ports or harbors, or a collection of sailing directions. Portolan maps all share the characteristic rhumbline networks, which emanate out from compass roses located at points on the map. These, better called windrose lines, are generated by observation and the compass, as Leo Bagrow states. the word is wrongly applied to the sea-charts of this period, since a loxodrome gives an accurate course only when the chart is drawn on a suitable projection. Cartometric investigation has revealed that no projection was used in the early charts and these charts, actually rough maps, were based on accounts by medieval Europeans who sailed the Mediterranean and Black Sea coasts. Such charts were later drafted for coastal resources in the Atlantic, frequently drawn on sheepskin vellum, portolan charts show coastal features and ports. During that period, smaller ships could use more of the coastline as harbours than in the present era and they might need to seek refuge more often, and crews intentionally beached some ships for maintenance and repairs. Thus, mariners sought to learn of protected bays or flat beaches, not only for safe harbour, thus the grid lines varied slightly for charts produced in different eras, due to the natural changes of the Earths magnetic declination. These lines are similar to the compass rose displayed on later maps, all portolan charts have wind roses, though not necessarily complete with the full thirty-two points, the compass rose. Seems to have been a Catalan innovation, the portolan combined the exact notations of the text of the periplus or pilot book with the decorative illustrations of a medieval T and O map. In addition, the charts provided realistic depictions of shores and they were meant for practical use by mariners of the period. Portolans were most useful in close quarters identification of landmarks, portolani were also useful for navigation in smaller bodies of water, such as the Mediterranean, Black, or Red Seas. The oldest extant portolan is the Carta Pisana, dating from approximately 1296 and this led towards two families of Portolan charts, the ones that are purely nautical and those that are nautical and geographical. The Catalan portolan charts are of second type, being usually made in Majorca. The copious number of Italian Portolan charts begins in mid-s. XIII, with the oldest called Carta Pisana and they introduced a novelty in the nautical cartography for they are geographical maps, all with common stylistic representation of certain accidents and geographical areas. The masterpiece of the Majorcan Portolan charts is the Catalan Atlas made by Abraham Cresques in 1375, Abraham Cresques was a Majorcan Jew who worked at the service of Pedro IV of Aragon. In his buxolarum workshop he was helped by his son Jafuda, the Atlas is a World Map, that is, world map and regions of the Earth with the various peoples who live there

Calcium hydroxide
–
Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca2. It is a crystal or white powder and is obtained when calcium oxide is mixed. It has many names including hydrated lime, caustic lime, builders lime, slack lime, cal, Calcium hydroxide is used in many applications, including food preparation. Limewater is the name for a saturated solution of calcium hydroxide. Calcium hydroxide is insoluble in water, with a solubility product Ksp of 5.5 × 10−6.4. Calcium hydroxide solutions can cause chemical burns, at high pH value, its solubility drastically decreases. This behavior is relevant to cement pastes, Ca2 → CaO + H2O Calcium hydroxide adopts a polymeric structure, as do all metal hydroxides. The structure is identical to that of Mg2, i. e. the cadmium iodide motif, strong hydrogen bonds exist between the layers. Calcium hydroxide is produced commercially by treating lime with water, CaO + H2O → Ca2 In the laboratory it can be prepared by mixing solutions of calcium chloride. The mineral form, portlandite, is rare but can be found in some volcanic, plutonic. It has also known to arise in burning coal dumps. CaOH has been detected in the atmosphere of S-type stars, one significant application of calcium hydroxide is as a flocculant, in water and sewage treatment. It forms a fluffy charged solid that aids in the removal of particles from water. This application is enabled by the low cost and low toxicity of calcium hydroxide and this conversion is part of the causticizing step in the Kraft process for making pulp. In Spanish, calcium hydroxide is called cal, corn cooked with cal becomes hominy, which significantly increases the bioavailability of niacin, and it is also considered tastier and easier to digest. In chewing coca leaves, calcium hydroxide is usually chewed alongside to keep the alkaloid stimulants chemically available for absorption by the body, similarly, Native Americans traditionally chewed tobacco leaves with calcium hydroxide derived from burnt mollusk shells to enhance the effects. It has also used by some indigenous American tribes as an ingredient in yopo. Calcium hydroxide is added to a bundle of areca nut

Paper quire
–
Various measures of paper quantity have been and are in use. Although there are no S. I. units such as quires and bales, there are ISO, the usual meaning is 25 sheets of the same size and quality, 1⁄20 of a ream of 500 sheets. Quires of 25 sheets are used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams. Quires of 15,18 or 20 sheets have also been used, the current word quire derives from OE quair or guaer, from OF quayer, cayer, from L. quaternum, by fours, fourfold. Later, when bookmaking switched to using paper and it possible to easily stitch 5 to 7 sheets at a time. In the Middle Ages, a quire was most often formed of 4 folded sheets of vellum or parchment, the term quaternion designates such a quire. A quire made of a folded sheet is a bifolium. This last meaning is preserved in the modern Italian term for quire, formerly, when paper was packed at the paper mill, the top and bottom quires were made up of slightly damaged sheets to protect the good quires. These outside quires were known as cassie quires, or cording quires and had only 20 sheets to the quire. The printer William Caslon in a book published in 1770 mentions both 24- and 25-sheet quires, he also details printers wastage, and the sorting and recycling of damaged cassie quires. An 1826 French manual on typography complained that cording quires from the Netherlands barely contained a single good sheet and it also became the name for any booklet small enough to be made from a single quire of paper. Simon Winchester, in The Surgeon of Crowthorne, cites a specific number, several European words for quire keep the meaning of book of paper, Ger. In blankbook binding, quire is a term indicating 80 pages, a ream of paper is a quantity of sheets of the same size and quality. International standards organizations define the ream as 500 identical sheets and this ream of 500 sheets is also known as a long ream, and is gradually replacing the old value of 480 sheets, now known as a short ream. Reams of 472 and 516 sheets are still current, but in retail outlets paper is sold in reams of 500. As an old UK and US unit, a ream was equal to 516 sheets. Certain types of specialist papers such as paper, greaseproof paper, handmade paper. However, the use of the word ream for quantities of paper other than 500 is now deprecated by such standards as ISO4046

Illuminated manuscript
–
An illuminated manuscript is a manuscript in which the text is supplemented with such decoration as initials, borders and miniature illustrations. Comparable Far Eastern and Mesoamerican works are described as painted, islamic manuscripts may be referred to as illuminated, illustrated or painted, though using essentially the same techniques as Western works. This article covers the technical, social and economic history of the subject, for an art-historical account, the earliest surviving substantive illuminated manuscripts are from the period 400 to 600, produced in the Kingdom of the Ostrogoths and the Eastern Roman Empire. The significance of these works lies not only in their inherent artistic and historical value, had it not been for the monastic scribes of Late Antiquity, most literature of Greece and Rome would have perished in Europe. As it was, the patterns of textual survivals were shaped by their usefulness to the severely constricted literate group of Christians, the majority of surviving manuscripts are from the Middle Ages, although many survive from the Renaissance, along with a very limited number from Late Antiquity. The majority of manuscripts are of a religious nature. However, especially from the 13th century onward, a number of secular texts were illuminated. Most illuminated manuscripts were created as codices, which had superseded scrolls, a very few illuminated manuscript fragments survive on papyrus, which does not last nearly as long as vellum or parchment. Most medieval manuscripts, illuminated or not, were written on parchment, beginning in the late Middle Ages manuscripts began to be produced on paper. Illuminated manuscripts continued to be produced in the early 16th century, Manuscripts are among the most common items to survive from the Middle Ages, many thousands survive. They are also the best surviving specimens of medieval painting, indeed, for many areas and time periods, they are the only surviving examples of painting. There are a few examples from later periods, the type of book that was most often heavily and richly illuminated, sometimes known as a display book, varied between periods. In the first millennium, these were most likely to be Gospel Books, such as the Lindisfarne Gospels, the Romanesque period saw the creation of many huge illuminated complete Bibles – one in Sweden requires three librarians to lift it. Many Psalters were also illuminated in both this and the Gothic period. Finally, the Book of Hours, very commonly the personal book of a wealthy layperson, was often richly illuminated in the Gothic period. Other books, both liturgical and not, continued to be illuminated at all periods, the Byzantine world also continued to produce manuscripts in its own style, versions of which spread to other Orthodox and Eastern Christian areas. See Medieval art for other regions, periods and types, reusing parchments by scraping the surface and reusing them was a common practice, the traces often left behind of the original text are known as palimpsests. The Gothic period, which saw an increase in the production of these beautiful artifacts, also saw more secular works such as chronicles

Sifrei Torah
–
A Sefer Torah is a handwritten copy of the Torah, the holiest book in Judaism. It must meet strict standards of production. The Torah scroll is used in the ritual of Torah reading during Jewish prayers. The text of the Torah is also printed and bound in book form for non-ritual functions. It is then known as a Chumash, and is accompanied by commentaries or translations. Torah reading from a Sefer Torah is traditionally reserved for Monday and Thursday mornings, as well as for Shabbat, the presence of a minyan is required for the reading of the Torah to be held in public during the course of the worship services. As the Torah is sung, following the often dense text is aided by a yad, according to halakha, a sefer Torah is a copy of the formal Hebrew text of the Torah hand-written on gevil or klaf by using a quill dipped in ink. Producing a sefer Torah fulfills one of the 613 commandments, an error during transcription may render the sefer Torah pasul. According to the Talmud, all scrolls must also be written on parchment that is treated with salt, flour. Scrolls not processed in this way are considered invalid, the calfskin or parchment on which the sacred Hebrew text is written is mounted into a wooden housing called עץ חיים in Hebrew. The housing has two rollers, each of which has two handles used for scrolling the text, four handles in all, most modern Sifrei Torah are written with forty-two lines of text per column. Very strict rules about the position and appearance of the Hebrew alphabet are observed, see for example the Mishnah Berurah on the subject. Any of several Hebrew scripts may be used, most of which are fairly ornate, some errors are inevitable in the course of production. If the error involves an other than the name of God. If the name of God is written in error, the page must be cut from the scroll and a new page added. The new page is sewn into the scroll to maintain continuity of the document, the old page is treated with appropriate respect, and is buried with respect rather than being otherwise destroyed or discarded. It is an honor to be chosen for this. It is a mitzvah for every Jewish male to either write or have written for him a Sefer Torah

Kosher
–
Kashrut is a set of Jewish religious dietary laws. Food that may be consumed according to halakha is termed kosher /ˈkoʊʃər/ in English, from the Ashkenazi pronunciation of the Hebrew term kashér, there are also laws regarding agricultural produce that might impact the suitability of food for consumption. Most of the laws of kashrut are derived from the Torahs Books of Leviticus. Their details and practical application, however, are set down in the oral law, while the Torah does not state the rationale for most kashrut laws, many reasons have been suggested, including philosophical, practical and hygienic. Over the past century, there have developed numerous rabbinical organizations that certify products, manufacturers, currently, about a sixth of American Jews or 0. 3% of the American population fully keep kosher, and many more abstain from some non-kosher foods, especially pork. Some Jewish scholars say that kashrut should be categorized as laws for which there is no particular explanation, in this line of thinking, the dietary laws were given as a demonstration of Gods authority, and man must obey without asking why. However, Maimonides believed that Jews were permitted to seek out reasons for the laws of the Torah, some theologians have said that the laws of kashrut are symbolic in character, Kosher animals represent virtues, while non-kosher animals represent vices. The 1st century BCE Letter of Aristeas argues that the laws have been given, to awake pious thoughts and to form the character. This view reappears in the work of the 19th century Rabbi Samson Raphael Hirsch, the Torah prohibits seething the kid in its mothers milk. While the Bible does not provide a reason, it has suggested that the practice was perceived as cruel. These sparks of Holiness are released whenever a Jew manipulates any object for a reason, however. The Hasidic argument is that animals are imbued with signs that reveal the release of these sparks, in 1953, David Macht, an Orthodox Jew and proponent of the theory of biblical scientific foresight, conducted toxicity experiments on many kinds of animals and fish. At the same time, these explanations are controversial, scholar Lester L. Grabbe, writing in the Oxford Bible Commentary on Leviticus, says n explanation now almost universally rejected is that the laws in this section have hygiene as their basis. Although some of the laws of ritual purity roughly correspond to ideas of physical cleanliness. For example, there is no evidence that the animals are intrinsically bad to eat or to be avoided in a Mediterranean climate. The laws of kashrut can be classified according to the origin of the prohibition, biblically prohibited foods include, Non-kosher animals and birds, mammals require certain identifying characteristics, while birds require a tradition that they can be consumed. All invertebrates are non-kosher apart from certain types of locust, on which most communities lack a clear tradition, no reptiles or amphibians are kosher. Carrion, meat from an animal that has not been slaughtered according to the laws of shechita

Johannes Gutenberg
–
Johannes Gensfleisch zur Laden zum Gutenberg was a German blacksmith, goldsmith, printer, and publisher who introduced printing to Europe. Gutenberg in 1439 was the first European to use the printing press and his truly epochal invention was the combination of these elements into a practical system that allowed the mass production of printed books and was economically viable for printers and readers alike. Gutenbergs method for making type is considered to have included a type metal alloy. The alloy was a mixture of lead, tin, and antimony that melted at a low temperature for faster and more economical casting, cast well. In Renaissance Europe, the arrival of mechanical movable type printing introduced the era of communication which permanently altered the structure of society. Gutenbergs printing technology spread rapidly throughout Europe and later the world and his major work, the Gutenberg Bible, has been acclaimed for its high aesthetic and technical quality. Gutenberg was born in the German city of Mainz, the youngest son of the upper-class merchant Friele Gensfleisch zur Laden, and his wife, Else Wyrich. It is assumed that he was baptized in the close to his birthplace of St. Christoph. According to some accounts, Friele was a goldsmith for the bishop at Mainz, Gutenbergs year of birth is not precisely known but was most likely around 1398. John Lienhard, technology historian, says Most of Gutenbergs early life is a mystery and his father worked with the ecclesiastic mint. Gutenberg grew up knowing the trade of goldsmithing and this is supported by historian Heinrich Wallau, who adds, In the 14th and 15th centuries his claimed a hereditary position as. Retainers of the household of the master of the archiepiscopal mint, in this capacity they doubtless acquired considerable knowledge and technical skill in metal working. They supplied the mint with the metal to be coined, changed the species of coins. Wallau adds, His surname was derived from the inhabited by his father and his paternal ancestors zu Laden. The house of Gänsfleisch was one of the families of the town. Patricians in Mainz were often named after houses they owned, around 1427, the name zu Gutenberg, after the family house in Mainz, is documented to have been used for the first time. In 1411, there was an uprising in Mainz against the patricians, as a result, the Gutenbergs are thought to have moved to Eltville am Rhein, where his mother had an inherited estate. According to historian Heinrich Wallau, All that is known of his youth is that he was not in Mainz in 1430 and it is presumed that he migrated for political reasons to Strasbourg, where the family probably had connections

Gutenberg Bible

The Gutenberg Bible was the first major book printed using mass-produced movable metal type in Europe. It marked the start of the Gutenberg Revolution and the age of the book in the West. Widely praised for its aesthetic and artistic qualities, the book has an iconic status. Written in Latin, the Catholic Gutenberg Bible is an edition of the Vulgate, printed by Johannes Gutenberg, in Mainz, in present-day Germany, in the 1450s. Since its publication,49 copies have survived, and they are considered to be among the most valuable books in the even though no complete copy has been sold since 1978. In March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, being displayed to promote the edition and it is not known how many copies were printed, with the 1455 letter citing sources for both 158 and 180 copies. The 36-line Bible, believed to be the second printed version of the Bible, is sometimes referred to as a Gutenberg Bible. The Gutenberg Bible, an edition of the Vulgate, contains the Latin version of the Hebrew Old Testament and it is mainly the work of Jerome who began his work on the translation in 380 AD, with emendations from the Parisian Bible tradition, and further divergences. The Bible was not Gutenbergs first work, preparation of the Bible probably began soon after 1450, and the first finished copies were available in 1454 or 1455. It is not known exactly how long the Bible took to print, the first precisely datable printing is the Gutenbergs 31-line Indulgence which is known to already exist on 22 October 1454. Gutenberg made three significant changes during the printing process, the first sheets were rubricated by being passed twice through the printing press, using black and then red ink. This was soon abandoned, with spaces being left for rubrication to be added by hand, some time later, after more sheets had been printed, the number of lines per page was increased from 40 to 42, presumably to save paper. Therefore, pages 1 to 9 and pages 256 to 265, page 10 has 41, and from there on the 42 lines appear. The increase in number was achieved by decreasing the interline spacing. Finally, the print run was increased, necessitating resetting those pages which had already been printed, the new sheets were all reset to 42 lines per page. Consequently, there are two settings in folios 1-32 and 129-158 of volume I and folios 1-16 and 162 of volume II. The most reliable information about the Bibles date comes from a letter, in March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, being displayed to promote the edition, in Frankfurt. It is not known how many copies were printed, with the 1455 letter citing sources for both 158 and 180 copies

Movable type
–
Movable type is the system and technology of printing and typography that uses movable components to reproduce the elements of a document usually on the medium of paper. In 1377, currently the oldest extant movable metal print book, the diffusion of both movable-type systems was, however, limited. Around 1450 Johannes Gutenberg made another version of a metal printing press in Europe, along with innovations in casting the type based on a matrix. The more limited number of characters needed for European languages was an important factor, Gutenberg was the first to create his type pieces from an alloy of lead, tin, and antimony—and these materials remained standard for 550 years. For alphabetic scripts, movable-type page setting was quicker than woodblock printing, the metal type pieces were more durable and the lettering was more uniform, leading to typography and fonts. The high quality and relatively low price of the Gutenberg Bible established the superiority of movable type in Europe, the printing press may be regarded as one of the key factors fostering the Renaissance and due to its effectiveness, its use spread around the globe. The 19th-century invention of hot metal typesetting and its successors caused movable type to decline in the 20th century, the technique of imprinting multiple copies of symbols or glyphs with a master type punch made of hard metal first developed around 3000 BC in ancient Sumer. These metal punch types can be seen as precursors of the letter punches adapted in later millennia to printing with metal type. Cylinder seals were used in Mesopotamia to create an impression on a surface by rolling the seal on wet clay and they were used to sign documents and mark objects as the owners property. By 650 BC the ancient Greeks were using larger diameter punches to imprint small page images onto coins and tokens, seals and stamps may have been precursors to movable type. A few authors even view the disc as technically meeting all definitional criteria to represent an early incidence of movable-type printing, recently it has been alleged by Jerome Eisenberg that the disk is a forgery. The Prüfening dedicatory inscription is medieval example of movable type stamps being used, yet copying books by hand was still labour-consuming. Not until the Xiping Era, towards the end of the Eastern Han Dynasty did sealing print and it was soon used for printing designs on fabrics, and later for printing texts. Woodblock printing, invented by about the 8th century during the Tang Dynasty, then carvers cut away the parts of the board that were not part of the character, so that the characters were cut in relief, completely differently from those cut intaglio. When printing, the characters would have some ink spread on them. With workers’ hands moving on the back of paper gently, characters would be printed on the paper, by the Song Dynasty, woodblock printing came to its heyday. Although woodblock printing played a role in spreading culture, there remained some apparent drawbacks. Firstly, carving the printing plate required considerable time, labour and materials, secondly, it was not convenient to store these plates, with woodblock printing, one printing plate could be used for tens of hundreds of books, playing a magnificent role in spreading culture

Printing press
–
A printing press is a device for applying pressure to an inked surface resting upon a print medium, thereby transferring the ink. The printing press was invented in the Holy Roman Empire by the German Johannes Gutenberg around 1440, the printing press spread within several decades to over two hundred cities in a dozen European countries. By 1500, printing presses in operation throughout Western Europe had already produced more than twenty million volumes, in the 16th century, with presses spreading further afield, their output rose tenfold to an estimated 150 to 200 million copies. The operation of a press became so synonymous with the enterprise of printing that it lent its name to a new branch of media. The sharp rise of learning and literacy amongst the middle class led to an increased demand for books which the time-consuming hand-copying method fell far short of accommodating. Technologies preceding the press led to the presss invention included, manufacturing of paper, development of ink, woodblock printing. At the same time, a number of products and technological processes had reached a level of maturity which allowed their potential use for printing purposes. The device was used from very early on in urban contexts as a cloth press for printing patterns. Gutenberg may have also inspired by the paper presses which had spread through the German lands since the late 14th century. Gutenberg adopted the design, thereby mechanizing the printing process. Printing, however, put a demand on the quite different from pressing. Gutenberg adapted the construction so that the power exerted by the platen on the paper was now applied both evenly and with the required sudden elasticity. To speed up the process, he introduced a movable undertable with a plane surface on which the sheets could be swiftly changed. The known examples range from Germany to England to Italy, however, the various techniques employed did not have the refinement and efficiency needed to become widely accepted. Gutenberg greatly improved the process by treating typesetting and printing as two separate work steps, a goldsmith by profession, he created his type pieces from a lead-based alloy which suited printing purposes so well that it is still used today. The mass production of metal letters was achieved by his key invention of a hand mould. Another factor conducive to printing arose from the existing in the format of the codex. Considered the most important advance in the history of the prior to printing itself

Bookbinding
–
Bookbinding is the process of physically assembling a book from an ordered stack of paper sheets that are folded together into sections or sometimes left as a stack of individual sheets. The stack is then bound together along one edge by either sewing with thread through the folds or by a layer of flexible adhesive, for protection, the bound stack is either wrapped in a flexible cover or attached to stiff boards. Finally, a cover is adhered to the boards and a label with identifying information is attached to the covers along with additional decoration. Bookbinding is a trade that relies on basic operations of measuring, cutting. A finished book depends on a minimum of two dozen operations to complete but sometimes more than double that according to the specific style. All operations have an order and each one relies on accurate completion of the previous step with little room for back tracking. An extremely durable binding can be achieved by using the best hand techniques, Bookbinding combines skills from other trades such as paper and fabric crafts, leather work, model making, and graphic arts. It requires knowledge about numerous varieties of book structures along with all the internal and external details of assembly, a working knowledge of the materials involved is required. Bookbinding is a craft of great antiquity, and at the same time. The division between craft and industry is not so wide as might at first be imagined and it is interesting to observe that the main problems faced by the mass-production bookbinder are the same as those that confronted the medieval craftsman or the modern hand binder. Before the computer age, the bookbinding trade involved two divisions, second was Letterpress binding which deals with making new books intended to be read from and includes fine binding, library binding, edition binding, and publishers bindings. A result of the new bindings is a third division dealing with the repair, restoration, with the digital age, personal computers have replaced the pen and paper based accounting that used to drive most of the work in the stationery binding industry. There is a grey area between the two divisions. There are cases where the printing and binding jobs are combined in one shop, a step up to the next level of mechanization is determined by economics of scale until you reach production runs of ten thousand copies or more in a factory employing a dozen or more workers. The craft of bookbinding probably originated in India, where religious sutras were copied on to palm leaves with a metal stylus, the leaf was then dried and rubbed with ink, which would form a stain in the wound. The finished leaves were given numbers, and two long twines were threaded through each end through wooden boards, making a palm-leaf book, when the book was closed, the excess twine would be wrapped around the boards to protect the manuscript leaves. Buddhist monks took the idea through Afghanistan to China in the first century BC, similar techniques can also be found in ancient Egypt where priestly texts were compiled on scrolls and books of papyrus. Another version of bookmaking can be seen through the ancient Mayan codex, writers in the Hellenistic-Roman culture wrote longer texts as scrolls, these were stored in boxes or shelving with small cubbyholes, similar to a modern winerack

Canvas
–
Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, and other items for which sturdiness is required. It is also used by artists as a painting surface. It is also used in such objects as handbags, electronic device cases. The word canvas is derived from the 13th century Anglo-French canevaz, both may be derivatives of the Vulgar Latin cannapaceus for made of hemp, originating from the Greek κάνναβις. Modern canvas is made of cotton or linen, although. It differs from other cotton fabrics, such as denim. Canvas comes in two types, plain and duck. The threads in duck canvas are more tightly woven, the term duck comes from the Dutch word for cloth, doek. In the United States, canvas is classified in two ways, by weight and by a number system. The numbers run in reverse of the weight so a number 10 canvas is lighter than number 4, canvas has become the most common support medium for oil painting, replacing wooden panels. One of the earliest surviving oils on canvas is a French Madonna with angels from around 1410 in the Gemäldegalerie, however, panel painting remained more common until the 16th century in Italy and the 17th century in Northern Europe. Mantegna and Venetian artists were among those leading the change, Venetian sail canvas was readily available, as lead-based paint is poisonous, care has to be taken in using it. Early canvas was made of linen, a sturdy brownish fabric of considerable strength, linen is particularly suitable for the use of oil paint. In the early 20th century, cotton canvas, often referred to as cotton duck, linen is composed of higher quality material, and remains popular with many professional artists, especially those who work with oil paint. Cotton duck, which stretches more fully and has an even, mechanical weave, the advent of acrylic paint has greatly increased the popularity and use of cotton duck canvas. Linen and cotton derive from two different plants, the flax plant and the cotton plant, respectively. Gessoed canvases on stretchers are also available and they are available in a variety of weights, light-weight is about 4 oz or 5 oz, medium-weight is about 7 oz or 8 oz, heavy-weight is about 10 oz or 12 oz. They are prepared with two or three coats of gesso and are ready for use straight away, artists desiring greater control of their painting surface may add a coat or two of their preferred gesso

Watercolour
–
Watercolor or watercolour, also aquarelle, a diminutive of the Latin for water, is a painting method in which the paints are made of pigments suspended in a water-based solution. Watercolor refers to both the medium and the resulting artwork, the traditional and most common support—material to which the paint is applied—for watercolor paintings is paper. Other supports include papyrus, bark papers, plastics, vellum, leather, fabric, wood, Watercolor paper is often made entirely or partially with cotton, which gives a good texture and minimizes distortion when wet. Watercolors are usually translucent, and appear luminous because the pigments are laid down in a form with few fillers obscuring the pigment colors. Watercolors can also be made opaque by adding Chinese white, in East Asia, watercolor painting with inks is referred to as brush painting or scroll painting. In Chinese, Korean and Japanese painting it has been the dominant medium, india, Ethiopia and other countries have long watercolor painting traditions as well. Fingerpainting with watercolor paints originated in mainland China, however, its continuous history as an art medium begins with the Renaissance. The German Northern Renaissance artist Albrecht Dürer, who painted several fine botanical, wildlife, an important school of watercolor painting in Germany was led by Hans Bol as part of the Dürer Renaissance. Despite this early start, watercolors were used by Baroque easel painters only for sketches, copies or cartoons. Notable early practitioners of watercolor painting were Van Dyck, Claude Lorrain, Giovanni Benedetto Castiglione, however, botanical illustration and wildlife illustration perhaps form the oldest and most important traditions in watercolor painting. Botanical illustrations became popular during the Renaissance, both as hand-tinted woodblock illustrations in books or broadsheets and as tinted ink drawings on vellum or paper. Wildlife illustration reached its peak in the 19th century with such as John James Audubon. Several factors contributed to the spread of watercolor painting during the 18th century, Watercolor artists were commonly brought with the geological or archaeological expeditions, funded by the Society of Dilettanti, to document discoveries in the Mediterranean, Asia, and the New World. This example popularized watercolors as a form of personal tourist journal, the confluence of these cultural, engineering, scientific, tourist, and amateur interests culminated in the celebration and promotion of watercolor as a distinctly English national art. William Blake published several books of hand-tinted engraved poetry, provided illustrations to Dantes Inferno, from the late 18th century through the 19th century, the market for printed books and domestic art contributed substantially to the growth of the medium. Satirical broadsides by Thomas Rowlandson, many published by Rudolph Ackermann, were extremely popular. Among the important and highly talented contemporaries of Turner and Girtin, were John Varley, John Sell Cotman, Anthony Copley Fielding, Samuel Palmer, William Havell, the Swiss painter Louis Ducros was also widely known for his large format, romantic paintings in watercolor. These societies provided annual exhibitions and buyer referrals for many artists, in particular, the graceful, lapidary, and atmospheric watercolors by Richard Parkes Bonington created an international fad for watercolor painting, especially in England and France in the 1820s

Old master print
–
An old master print is a work of art produced by a printing process within the Western tradition. Fifteenth-century prints are rare that they are classed as old master prints even if they are of crude or merely workmanlike artistic quality. A date of about 1830 is usually taken as marking the end of the period whose prints are covered by this term, the main techniques used, in order of their introduction, are woodcut, engraving, etching, mezzotint and aquatint, although there are others. Different techniques are combined in a single print. With rare exceptions printed on textiles, such as silk, or on vellum, many great European artists, such as Albrecht Dürer, Rembrandt, and Francisco Goya, were dedicated printmakers. In their own day, their international reputations largely came from their prints, influences between artists were also mainly transmitted beyond a single city by prints, for the same reason. Prints therefore are frequently brought up in detailed analyses of individual paintings in art history, today, thanks to colour photo reproductions, and public galleries, their paintings are much better known, whilst their prints are only rarely exhibited, for conservation reasons. But some museum print rooms allow visitors to see their collection, the oldest technique is woodcut, or woodblock printing, which was invented as a method for printing on cloth in China, and perhaps separately in Egypt in the Byzantine period. This had reached Europe via the Byzantine or Islamic worlds before 1300, religious images and playing cards are documented as being produced on paper, probably printed, by a German in Bologna in 1395. However, the most impressive printed European images to survive from before 1400 are printed on cloth, for use as hangings on walls or furniture, including altars, some were used as a pattern to embroider over. Some religious images were used as bandages, to speed healing, the earliest print images are mostly of a high artistic standard, and were clearly designed by artists with a background in painting. Whether these artists cut the blocks themselves, or only inked the design on the block for another to carve, is not known, the great majority of surviving 15th-century prints are religious, although these were probably the ones more likely to survive. Their makers were sometimes called Jesus maker or saint-maker in documents, as with manuscript books, monastic institutions sometimes produced, and often sold, prints. No artists can be identified with specific woodcuts until towards the end of the century, the little evidence we have suggests that woodcut prints became relatively common and cheap during the fifteenth century, and were affordable by skilled workers in towns. For example, what may be the earliest surviving Italian print, the school caught fire, and the crowd who gathered to watch saw the print carried up into the air by the fire, before falling down into the crowd. This was regarded as an escape and the print was carried to Forlì Cathedral. Like the majority of prints before approximately 1460, only a single impression of this print has survived, Woodcut blocks are printed with light pressure, and are capable of printing several thousand impressions, and even at this period some prints may well have been produced in that quantity. Many prints were hand-coloured, mostly in watercolour, in fact the hand-colouring of prints continued for many centuries, Italy, Germany, France and the Netherlands were the main areas of production, England does not seem to have produced any prints until about 1480

Gilding
–
The term gilding covers a number of decorative techniques for applying fine gold leaf or powder to solid surfaces such as wood, stone, or metal to give a thin coating of gold. A gilded object is described as gilt. Where metal is gilded, it was silver in the West, to make silver-gilt objects, but gilt-bronze is commonly used in China. Methods of gilding include hand application and glueing, chemical gilding, and electroplating, parcel-gilt objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, herodotus mentions that the Egyptians gilded wood and metals, and many such objects have been excavated. Certain Ancient Greek statues of great prestige were chryselephantine, i. e. made of gold and ivory, extensive ornamental gilding was also used in the ceiling coffers of the Propylaea. But he adds that luxury advanced on them so rapidly that in very little time you see all, even private and poor people, gild the walls, vaults. Owing to the thickness of the gold leaf used in ancient gilding. Fire-gilding of metal goes back at least to the 4th century BC, in Europe, silver-gilt has always been more common than gilt-bronze, but in China the opposite has been the case. The ancient Chinese also developed the gilding of porcelain, which was taken up by the French. Modern gilding is applied to numerous and diverse surfaces and by various processes, mechanical gilding includes all the operations in which gold leaf is prepared, and the processes to mechanically attach the gold onto surfaces. The process is completed by cold burnishing, overlaying or folding or hammering on gold foil or gold leaf is the simplest and most ancient method, and is mentioned in Homers Odyssey and the Old Testament. The Ram in a Thicket of about 2600–2400 BCE from Ur uses this technique on wood, the next advances involved two simple processes. The first involves gold leaf, which is gold that is hammered or cut very thin sheets. If gilding on canvas or on wood, the surface was often first coated with gesso, gesso is a substance made of finely ground gypsum or chalk mixed with glue. Other gilding processes involved using the gold as pigment in paint, then the gold was applied in the same way as with any paint. Sometimes, after either gold-leafing or gold-painting, the artist would heat the piece enough to melt the gold slightly and these techniques remained the only alternatives for materials like wood, leather, and the vellum pages of illuminated manuscripts. Chemical gilding embraces those processes in which the gold is at some stage of chemical combination and these include, In this process the gold is obtained in a state of extremely fine division, and applied by mechanical means

Act of Parliament
–
Acts of Parliament, also called primary legislation, are statutes passed by a parliament. Act of the Oireachtas is an equivalent term used in the Republic of Ireland where the legislature is known by its Irish name. It is also comparable to an Act of Congress in the United States, a draft Act of Parliament is known as a bill. In territories with a Westminster system, most bills that have any possibility of becoming law are introduced into parliament by the government. This will usually happen following the publication of a paper, setting out the issues. A bill may also be introduced into parliament without formal government backing, in territories with a multicameral parliament, most bills may be first introduced in any chamber. However, certain types of legislation are required, either by convention or by law. For example, bills imposing a tax, or involving public expenditure, are introduced into the House of Commons in the United Kingdom, Canadas House of Commons, conversely, bills proposed by the Law Commission and consolidation bills traditionally start in the House of Lords. Once introduced, a bill must go through a number of stages before it can become law, in theory, this allows the bills provisions to be debated in detail, and for amendments to the original bill to also be introduced, debated, and agreed to. In bicameral parliaments, a bill that has been approved by the chamber into which it was introduced then sends the bill to the other chamber, broadly speaking, each chamber must separately agree to the same version of the bill. Finally, the bill receives assent, in most territories this is merely a formality. In some countries, such as in Spain and Portugal, the term for a bill differs depending on whether it is initiated by the government, again, the second reading of a Government bill is usually approved. A defeat for a Government bill on this reading signifies a major loss, if the bill is read a second time, it is then considered in detail Consideration in detail, This usually takes place on the floor of the House. Generally, committees sit on the floor of the House and consider the bill in detail, third reading, A debate on the final text of the bill, as amended. Very rarely do debates occur during this stage, passage, The bill is then sent to the other House, which may amend it. If the other House amends the bill, the bill and amendments are posted back to the original House for a further stage, the State of Queenslands Parliament is unicameral and skips this and the rest of the stages. Consideration of Senate/Representatives amendments, The House in which the bill originated considers the amendments made in the other House and it may agree to them, amend them, propose other amendments in lieu, or reject them. However, the Senate may not amend money bills, though it can request the House to make amendments, a bill may pass backwards and forwards several times at this stage, as each House amends or rejects changes proposed by the other

Republic of Ireland
–
Ireland, also known as the Republic of Ireland, is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the part of the island. The state shares its land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint Georges Channel to the south-east, and it is a unitary, parliamentary republic. The head of government is the Taoiseach, who is elected by the Dáil and appointed by the President, the state was created as the Irish Free State in 1922 as a result of the Anglo-Irish Treaty. It was officially declared a republic in 1949, following the Republic of Ireland Act 1948, Ireland became a member of the United Nations in December 1955. It joined the European Economic Community, the predecessor of the European Union, after joining the EEC, Ireland enacted a series of liberal economic policies that resulted in rapid economic growth. The country achieved considerable prosperity between the years of 1995 and 2007, which known as the Celtic Tiger period. This was halted by a financial crisis that began in 2008. However, as the Irish economy was the fastest growing in the EU in 2015, Ireland is again quickly ascending league tables comparing wealth and prosperity internationally. For example, in 2015, Ireland was ranked as the joint sixth most developed country in the world by the United Nations Human Development Index and it also performs well in several national performance metrics, including freedom of the press, economic freedom and civil liberties. Ireland is a member of the European Union and is a member of the Council of Europe. The 1922 state, comprising 26 of the 32 counties of Ireland, was styled, the Constitution of Ireland, adopted in 1937, provides that the name of the State is Éire, or, in the English language, Ireland. Section 2 of the Republic of Ireland Act 1948 states, It is hereby declared that the description of the State shall be the Republic of Ireland. The 1948 Act does not name the state as Republic of Ireland, because to have done so would have put it in conflict with the Constitution. The government of the United Kingdom used the name Eire, and, from 1949, Republic of Ireland, for the state, as well as Ireland, Éire or the Republic of Ireland, the state is also referred to as the Republic, Southern Ireland or the South. In an Irish republican context it is referred to as the Free State or the 26 Counties. From the Act of Union on 1 January 1801, until 6 December 1922, during the Great Famine, from 1845 to 1849, the islands population of over 8 million fell by 30%

House of Lords
–
The House of Lords of the United Kingdom, referred to ceremonially as the House of Peers, is the upper house of the Parliament of the United Kingdom. Like the House of Commons, it meets in the Palace of Westminster, officially, the full name of the house is, The Right Honourable the Lords Spiritual and Temporal of the United Kingdom of Great Britain and Northern Ireland in Parliament assembled. Unlike the elected House of Commons, all members of the House of Lords are appointed, the membership of the House of Lords is drawn from the peerage and is made up of Lords Spiritual and Lords Temporal. The Lords Spiritual are 26 bishops in the established Church of England, of the Lords Temporal, the majority are life peers who are appointed by the monarch on the advice of the Prime Minister, or on the advice of the House of Lords Appointments Commission. However, they include some hereditary peers including four dukes. Very few of these are female since most hereditary peerages can only be inherited by men, while the House of Commons has a defined 650-seat membership, the number of members in the House of Lords is not fixed. There are currently 805 sitting Lords, the House of Lords is the only upper house of any bicameral parliament to be larger than its respective lower house. The House of Lords scrutinises bills that have approved by the House of Commons. It regularly reviews and amends Bills from the Commons, while it is unable to prevent Bills passing into law, except in certain limited circumstances, it can delay Bills and force the Commons to reconsider their decisions. In this capacity, the House of Lords acts as a check on the House of Commons that is independent from the electoral process, Bills can be introduced into either the House of Lords or the House of Commons. Members of the Lords may also take on roles as government ministers, the House of Lords has its own support services, separate from the Commons, including the House of Lords Library. The Queens Speech is delivered in the House of Lords during the State Opening of Parliament, the House also has a Church of England role, in that Church Measures must be tabled within the House by the Lords Spiritual. This new parliament was, in effect, the continuation of the Parliament of England with the addition of 45 MPs and 16 Peers to represent Scotland, the Parliament of England developed from the Magnum Concilium, the Great Council that advised the King during medieval times. This royal council came to be composed of ecclesiastics, noblemen, the first English Parliament is often considered to be the Model Parliament, which included archbishops, bishops, abbots, earls, barons, and representatives of the shires and boroughs of it. The power of Parliament grew slowly, fluctuating as the strength of the monarchy grew or declined, for example, during much of the reign of Edward II, the nobility was supreme, the Crown weak, and the shire and borough representatives entirely powerless. In 1569, the authority of Parliament was for the first time recognised not simply by custom or royal charter, further developments occurred during the reign of Edward IIs successor, Edward III. It was during this Kings reign that Parliament clearly separated into two chambers, the House of Commons and the House of Lords. The authority of Parliament continued to grow, and, during the fifteenth century

Hancock was the Minister for the Cabinet Office and Paymaster General and he previously served as jointly Minister of State for Business and Enterprise and Minister of State for Energy in the Conservative-Liberal Democrat Coalition Government. Hancock was educated at Farndon County Primary School, in Farndon, Cheshire, the Kings School, an independent school in Chester in Cheshire, and West Cheshire College, a further education college. He gained a degree in Philosophy, Politics and Economics from Exeter College, University of Oxford, Hancock has been a member of the Conservative Party since 1999. After university, Hancock briefly worked for his family’s computer software company, before moving to London to work as an economist at the Bank of England, specialising in the housing market. In 2005 he became an adviser to the Shadow Chancellor of the Exchequer, George Osborne. He stepped down from his role with the party in February 2010 after being selected for the six potential candidates for the West Suffolk constituency in the 2010 general election. Hancock narrowly won the selection contest, which place in Mildenhall. Hancock won the West Suffolk seat with 24,312 votes,13,050 votes ahead of Liberal Democrat candidate, in June, Hancock was elected to the Public Accounts Committee, the select committee responsible for overseeing government expenditures to ensure they are effective and honest. The frequency of his appearances in the House and contributions to debates are well above average and he has voted for tuition fees, encouraging occupational pensions, on 26 November 2011 he was on the panel for BBC Radio 4s Any Questions. In January 2013, he was accused of dishonesty by Daybreak presenter Matt Barbet after claiming he had excluded from a discussion about apprentices after turning up just 30 seconds late. Barbet said Hancock knew he was more than a minute late. His opponent expressed surprise that a minister whose Government berates shirkers couldnt be bothered to get out of bed to defend his own policy, in October 2013, he was promoted to Minister of State for Skills & Enterprise in a government reshuffle. In the July 2014 cabinet reshuffle, he was promoted again, this time to Minister of State for Business and Enterprise, Minister of State for Energy, and Minister of State for Portsmouth. On 27 July he announced protection for National Parks — seen as a method of reducing anger in Conservative constituencies ahead of the election. Interviewed on the Today programme, he rejected the suggestion that fracking was highly unpopular, in October 2014, he apologized after retweeting a poem suggesting that the Labour Party was full of queers, describing his actions as a total accident. Hancock became Minister for the Cabinet Office and Paymaster General on 11 May 2015 and he headed David Cameron’s earn or learn taskforce which aimed to have every young person earning or learning from April 2017

Cabinet Office
–
The Cabinet Office is a department of the Government of the United Kingdom responsible for supporting the Prime Minister and Cabinet of the United Kingdom. It is composed of units that support Cabinet committees and which co-ordinate the delivery of government objectives via other departments. It currently has just over 2,000 staff, most of work in Whitehall. Staff working in the Prime Ministers Office are part of the Cabinet Office and this also includes working with the Treasury to drive efficiency and reform across the public sector. Other functions include oversight of the Crown Commercial Service and the accreditation of Social Impact Contractors, the department was formed in December 1916 from the secretariat of the Committee of Imperial Defence under Sir Maurice Hankey, the first Cabinet Secretary. Traditionally the most important part of the Cabinet Offices role was facilitating collective decision-making by the Cabinet and it also contains miscellaneous units that do not sit well in other departments. For example, The Historical Section was founded in 1906 as part of the Committee for Imperial Defence and is concerned with Official Histories, the Joint Intelligence Committee was founded in 1936 and transferred to the department in 1957. It deals with intelligence assessments and directing the national organisations of the UK. The Ceremonial Branch was founded in 1937 and transferred to the department in 1981 and it was originally concerned with all ceremonial functions of state, but today it handles honours and appointments. In modern times the Cabinet Office often takes on responsibility for areas of policy that are the priority of the Government of the time, the units that administer these areas migrate in and out of the Cabinet Office as government priorities change. The Cabinet Office Ministers are as follows, All of the Cabinet Offices ministers are Cabinet members, the Cabinet Secretary and Head of the Home Civil Service is Sir Jeremy Heywood, the Permanent Secretary and Chief Executive of the Home Civil Service is John Manzoni. The Cabinet Office also supports the work of, the Leader of the House of Commons, the Leader of the House of Lords, and the Whips Office. Cabinet Committees have two key purposes, To relieve the burden on the Cabinet by dealing with business that does not need to be discussed at full Cabinet. Appeals to the Cabinet should be infrequent, and Ministers chairing Cabinet Committees should exercise discretion in advising the Prime Minister whether to allow them. To support the principle of responsibility by ensuring that, even though a question may never reach the Cabinet itself. In this way, the judgement is sufficiently authoritative that Government as a whole can be expected to accept responsibility for it. In this sense, Cabinet Committee decisions have the authority as Cabinet decisions. The main building of the Cabinet Office is at 70 Whitehall, remains of Henry VIIIs tennis courts from the Palace of Whitehall can be seen within the building

Newport Pagnell is a town in Buckinghamshire, England. In the Borough of Milton Keynes, it is separated from Milton Keynes itself by the M1 motorway, on which is Newport Pagnell services. The town was first mentioned in the Domesday Book of 1086 as Neuport, Old English for New Market Town, the suffix Pagnell came later when the manor passed into the hands of the Pagnell family. It was the town of the Three Hundreds of Newport. There were also at one time two hospitals in Newport Pagnell and six fairs were held for the townsfolk throughout the year, Newport Pagnell became the headquarters of Newport Pagnell Rural District under the Local Government Act 1894. In 1897, Newport Pagnell became the civil parish comprising the newly created Newport Pagnell Urban District. For a hundred years, Newport Pagnell was served by Newport Pagnell railway station the terminus on Wolverton to Newport Pagnell branch line, there is a plaque near the footbridge at the side that gives details of its history and construction placed there by Newport Pagnell Historical Society. Between 1817 and 1864, the town was linked to the Grand Junction Canal at Great Linford via the Newport Pagnell Canal, from 1954, until recently, Tickford Street in the town was the home to the prestigious sports car manufacturer Aston Martin. The Newport Pagnell factory was considered outdated and a new facility was built near Gaydon. The land behind these has been purchased by Tesco and the giant had planned to build an outlet on the site. In 2012 the service facility was completely modernised and now houses a bespoke sales department. The town is home to the only remaining vellum manufacturer in the United Kingdom, William Cowley. The modern civil parish of Newport Pagnell stops at the M1, the parish church is dedicated to St Peter and St Paul. The Office for National Statistics regards Newport Pagnell as part of the Milton Keynes Urban Area and its population in 1971 was 6,000, by 2001 it had reached 15,020. The Borough Council projects that the population will remain stable at this level. The people of Newport Pagnell are known as Pagnellions, Newport Pagnell has a Non-League football team Newport Pagnell Town F. C. nicknamed the Swans, who play at The Pavilion on Willen Road.

Development in this region is restricted by the Metropolitan Green Belt. Other large settlements include the county town of Aylesbury, Marlow in the south near the Thames and Princes Risborough in the west near Oxford. Some areas without rail links to London, such as around the old county town of Buckingham. The largest town is Milton Keynes in the northeast, which with the area is administered as a unitary authority separately to the rest of Buckinghamshire. The remainder of the county is administered by Buckinghamshire County Council as a non-metropolitan county, in national elections, Buckinghamshire is considered a reliable supporter of the Conservative Party. A large part of the Chiltern Hills, an Area of Outstanding Natural Beauty, runs through the south of the county and attracts many walkers, in this area older buildings are often made from local flint and red brick. Chequers, an estate owned by the government, is the country retreat of the incumbent Prime Minister. To the north of the county lies rolling countryside in the Vale of Aylesbury, the Thames forms part of the county’s southwestern boundary. Notable service amenities in the county are Pinewood Film Studios, Dorney rowing lake, many national companies have offices in Milton Keynes. Heavy industry and quarrying is limited, with agriculture predominating after service industries, the name Buckinghamshire is Anglo-Saxon in origin and means The district of Buccas home. Buccas home refers to Buckingham in the north of the county, the county has been so named since about the 12th century, however, the county has existed since it was a subdivision of the kingdom of Mercia. Historically, the biggest change to the county came in the 19th century, Buckinghamshire is a popular home for London commuters, leading to greater local affluence, however, some pockets of relative deprivation remain. As a result, most county institutions are now based in the south of the county or Milton Keynes, the county can be split into two sections geographically. The county includes parts of two of the four longest rivers in England, the River Thames forms the southern boundary with Berkshire, which has crept over the border at Eton and Slough so that the river is no longer the sole boundary between the two counties. The River Great Ouse rises just outside the county in Northamptonshire and flows east through Buckingham, Milton Keynes, the main branch of the Grand Union Canal passes through the county as do its arms to Slough, Aylesbury, Wendover and Buckingham. The canal has been incorporated into the landscaping of Milton Keynes, the southern part of the county is dominated by the Chiltern Hills. The two highest points in Buckinghamshire are Haddington Hill in Wendover Woods at 267 metres above sea level, quarrying has taken place for chalk, clay for brickmaking and gravel and sand in the river valleys. Flint, also extracted from quarries, was used to build older local buildings

Cotton
–
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose, under natural conditions, the cotton bolls will tend to increase the dispersal of the seeds. The plant is a native to tropical and subtropical regions around the world, including the Americas, Africa. The greatest diversity of wild species is found in Mexico, followed by Australia. Cotton was independently domesticated in the Old and New Worlds, the fiber is most often spun into yarn or thread and used to make a soft, breathable textile. Current estimates for world production are about 25 million tonnes or 110 million bales annually, China is the worlds largest producer of cotton, but most of this is used domestically. The United States has been the largest exporter for many years, in the United States, cotton is usually measured in bales, which measure approximately 0.48 cubic meters and weigh 226.8 kilograms. Cotton cultivation in the region is dated to the Indus Valley Civilization, the Indus cotton industry was well-developed and some methods used in cotton spinning and fabrication continued to be used until the industrialization of India. Between 2000 and 1000 BC cotton became widespread across much of India, for example, it has been found at the site of Hallus in Karnataka dating from around 1000 BC. Cotton fabrics discovered in a cave near Tehuacán, Mexico have been dated to around 5800 BC, the domestication of Gossypium hirsutum in Mexico is dated between 3400 and 2300 BC. Cotton was grown upriver, made into nets, and traded with fishing villages along the coast for supplies of fish. The Spanish who came to Mexico and Peru in the early 16th century found the people growing cotton and this may be a reference to tree cotton, Gossypium arboreum, which is a native of the Indian subcontinent. According to the Columbia Encyclopedia, Cotton has been spun, woven and it clothed the people of ancient India, Egypt, and China. Hundreds of years before the Christian era, cotton textiles were woven in India with matchless skill, in Iran, the history of cotton dates back to the Achaemenid era, however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran, in Persian poets poems, especially Ferdowsis Shahname, there are references to cotton. Marco Polo refers to the products of Persia, including cotton. John Chardin, a French traveler of the 17th century who visited the Safavid Persia, during the Han dynasty, cotton was grown by Chinese peoples in the southern Chinese province of Yunnan. Mohamed Ali Pasha accepted the proposition and granted himself the monopoly on the sale and export of cotton in Egypt, and later dictated cotton should be grown in preference to other crops

Torah
–
The Torah is the central reference of Judaism. It has a range of meanings and it can most specifically mean the first five books of the twenty-four books of the Tanakh, and it usually includes the rabbinic commentaries. In rabbinic literature the word Torah denotes both the five books and the Oral Torah, the Oral Torah consists of interpretations and amplifications which according to rabbinic tradition have been handed down from generation to generation and are now embodied in the Talmud and Midrash. According to the Midrash, the Torah was created prior to the creation of the world, traditionally, the words of the Torah are written on a scroll by a scribe in Hebrew. A Torah portion is read publicly at least once every three days in the presence of a congregation, reading the Torah publicly is one of the bases for Jewish communal life. The word Torah in Hebrew is derived from the root ירה, the meaning of the word is therefore teaching, doctrine, or instruction, the commonly accepted law gives a wrong impression. Other translational contexts in the English language include custom, theory, guidance, the earliest name for the first part of the Bible seems to have been The Torah of Moses. This title, however, is neither in the Torah itself. It appears in Joshua and Kings, but it cannot be said to refer there to the entire corpus, in contrast, there is every likelihood that its use in the post-Exilic works was intended to be comprehensive. Other early titles were The Book of Moses and The Book of the Torah, Christian scholars usually refer to the first five books of the Hebrew Bible as the Pentateuch, a term first used in the Hellenistic Judaism of Alexandria, meaning five books, or as the Law. The Torah starts from the beginning of Gods creating the world, through the beginnings of the people of Israel, their descent into Egypt, and it ends with the death of Moses, just before the people of Israel cross to the promised land of Canaan. Interspersed in the narrative are the teachings given explicitly or implicitly embedded in the narrative. This is followed by the story of the three patriarchs, Joseph and the four matriarchs, God gives to the patriarchs a promise of the land of Canaan, but at the end of Genesis the sons of Jacob end up leaving Canaan for Egypt due to a regional famine. They had heard there was a grain storage and distribution facility in Egypt. Exodus begins the story of Gods revelation to his people of Israel through Moses, Moses receives the Torah from God, and teaches His laws and Covenant to the people of Israel. It also talks about the first violation of the covenant when the Golden Calf was constructed, Exodus includes the instructions on building the Tabernacle and concludes with its actual construction. Leviticus begins with instructions to the Israelites on how to use the Tabernacle, leviticus 26 provides a detailed list of rewards for following Gods commandments and a detailed list of punishments for not following them. Numbers tells how Israel consolidated itself as a community at Sinai, set out from Sinai to move towards Canaan, even Moses sins and is told he would not live to enter the land

Calligraphy
–
Calligraphy is a visual art related to writing. It is the design and execution of lettering with a broad tip instrument, brush, a contemporary calligraphic practice can be defined as, the art of giving form to signs in an expressive, harmonious, and skillful manner. Modern calligraphy ranges from functional inscriptions and designs to fine-art pieces where the letters may or may not be readable, classical calligraphy differs from typography and non-classical hand-lettering, though a calligrapher may practice both. It is also used for props and moving images for film and television, testimonials, birth and death certificates, maps, the principal tools for a calligrapher are the pen and the brush. Calligraphy pens write with nibs that may be flat, round, for some decorative purposes, multi-nibbed pens—steel brushes—can be used. However, works have also created with felt-tip and ballpoint pens. There are some styles of calligraphy, like Gothic script, which require a stub nib pen, Writing ink is usually water-based and is much less viscous than the oil-based inks used in printing. Normally, light boxes and templates are used to achieve straight lines without pencil markings detracting from the work, ruled paper, either for a light box or direct use, is most often ruled every quarter or half inch, although inch spaces are occasionally used. This is the case with litterea unciales, and college-ruled paper often acts as a guideline well, common calligraphy pens and brushes are, Quill Dip pen Ink brush Qalam Fountain pen Western calligraphy is recognizable by the use of the Latin script. The Latin alphabet appeared about 600 BC, in Rome, and by the first century developed into Roman imperial capitals carved on stones, Rustic capitals painted on walls, in the second and third centuries the uncial lettering style developed. As writing withdrew to monasteries, uncial script was more suitable for copying the Bible. It was the monasteries which preserved calligraphic traditions during the fourth and fifth centuries, at the height of the Empire, its power reached as far as Great Britain, when the empire fell, its literary influence remained. The Semi-uncial generated the Irish Semi-uncial, the small Anglo-Saxon, each region developed its own standards following the main monastery of the region, which are mostly cursive and hardly readable. Christian churches promoted the development of writing through the copying of the Bible, particularly the New Testament. Two distinct styles of writing known as uncial and half-uncial developed from a variety of Roman bookhands, the 7th-9th centuries in northern Europe were the heyday of Celtic illuminated manuscripts, such as the Book of Durrow, Lindisfarne Gospels and the Book of Kells. Charlemagnes devotion to improved scholarship resulted in the recruiting of a crowd of scribes, according to Alcuin, Alcuin developed the style known as the Caroline or Carolingian minuscule. The first manuscript in hand was the Godescalc Evangelistary — a Gospel book written by the scribe Godescalc. Carolingian remains the one hand from which modern booktype descends

Banjo
–
The banjo is a four-, five- or six-stringed instrument with a thin membrane stretched over a frame or cavity as a resonator, called the head. The membrane, or head, is made of plastic, although animal skin is still occasionally but rarely used. Early forms of the instrument were fashioned by Africans in America, the banjo is frequently associated with country, folk, Irish traditional and bluegrass music. Historically, the banjo occupied a place in African American traditional music. The banjo, with the fiddle, is a mainstay of American old-time music and it is also very frequently used in Traditional Jazz. The modern banjo derives from instruments that had used in the Caribbean since the 17th century by enslaved people taken from West Africa. Written references to the banjo in North America appear in the 18th century, the etymology of the name banjo is uncertain. The word could have come from the Yoruba word Bami jo and it may derive from the Kimbundu word mbanza. A Banza, a five double string courses Portuguese viuhela with two short strings, mbanza is a string African instrument that has been built after the Portuguese Banza. Banza is quite similar to Banjo, various instruments in Africa, chief among them the kora, feature a skin head and gourd body. Banjos with fingerboards and tuning pegs are known from the Caribbean as early as the 17th century, 18th- and early 19th-century writers transcribed the name of these instruments variously as bangie, banza, bonjaw, banjer and banjar. Instruments similar to the banjo have been played in many countries, another likely relative of the banjo is the akonting, a spike folk lute played by the Jola tribe of Senegambia, and the ubaw-akwala of the Igbo. Early, African-influenced banjos were built around a body and a wooden stick neck. These instruments had varying numbers of strings, though often including some form of drone, the five-string banjo was popularized by Joel Walker Sweeney, an American minstrel performer from Appomattox Court House, Virginia. In the 1830s Sweeney became the first white performer to play the banjo on stage and his version of the instrument replaced the gourd with a drum-like sound box and included four full-length strings alongside a short fifth string. This new banjo was at first tuned dGdf♯a, though by the 1890s this had been transposed up to gcgbd, Banjos were introduced in Britain by Sweeneys group, the American Virginia Minstrels, in the 1840s, and became very popular in music halls. In the Antebellum South, many black slaves played the banjo, two techniques closely associated with the five-string banjo are rolls and drones. Rolls are right hand fingering pattern that consist of eight notes that subdivide each measure

Paper size
–
Many paper size standards conventions have existed at different times and in different countries. Today, the A and B series of ISO216, which includes the commonly used A4 size, are the standard used by almost every country. In some areas under strong US influence, Letter is more prevalent, Paper sizes affect writing paper, stationery, cards, and some printed documents. The international standard for envelopes is the C series of ISO269, the international paper size standard is ISO216. It is based on the German DIN476 standard for paper sizes, ISO paper sizes are all based on a single aspect ratio of square root of 2, or approximately 1,1.4142. There are different series, as well as several extensions, the following international paper sizes are included in Cascading Style Sheets, A3, A4, A5, B4, B5. The base A0 size of paper is defined as having an area of 1 m2, rounded to the nearest millimetre, that is 841 by 1,189 millimetres. Successive paper sizes in the series A1, A2, A3 and this also effectively halves the area of each sheet. The most frequently used paper size is A4 measuring 210 by 297 millimetres, folded brochures of any size can be made by using sheets of the next larger size, e. g. A4 sheets are folded to make A5 brochures. The system allows scaling without compromising the aspect ratio from one size to another—as provided by office photocopiers, similarly, two sheets of A4 can be scaled down and fit exactly on 1 sheet without any cutoff or margins. The behavior of the ratio is easily proven, on a sheet of paper, let a be the long side and b be the short side, thus. When the sheet of paper is folded in half widthwise, let c be the length of the new short side, c = a/2. If we take the ratio of the folded paper we have, b c = b a 2 =2 a b =22 =2 Therefore. The advantages of basing a paper size upon an aspect ratio of √2 were first noted in 1786 by the German scientist and philosopher Georg Christoph Lichtenberg. The formats that became A2, A3, B3, B4 and B5 were developed in France on proposition of the mathematician Lazare Carnot, early in the 20th century, Dr Walter Porstmann turned Lichtenbergs idea into a proper system of different paper sizes. Porstmanns system was introduced as a DIN standard in Germany in 1922, even today, the paper sizes are called DIN A4 in everyday use in Germany and Austria. The DIN476 standard spread quickly to other countries, by 1977, A4 was the standard letter format in 88 of 148 countries. Today the standard has been adopted by all countries in the world except the United States, in Mexico, Costa Rica, Colombia, Venezuela, Chile, and the Philippines, the US letter format is still in common use, despite their official adoption of the ISO standard

Architectural plan
–
This effort could also include both the design of new buildings and other structures, as well as the planning for reconstruction of early historic structures. A building is a structure with a roof and walls standing more or less permanently in one place. To better understand the term building compare the list of nonbuilding structures, the gallery below gives an overview of different types of building. The practice of designing, constructing, and operating buildings is most usually a collective effort of different groups of professionals, depending on the size, complexity, and purpose of a particular building project. A design process may include a series of steps followed by designers, depending on the product or service, some of these stages may be irrelevant, ignored in real-world situations in order to save time, reduce cost, or because they may be redundant in the situation. Architectural drawings are made according to a set of conventions, which include particular views, sheet sizes, units of measurement and scales, annotation and cross referencing. Conventionally, drawings were made in ink on paper or a similar material, the twentieth century saw a shift to drawing on tracing paper, so that mechanical copies could be run off efficiently. Architectural design values make up an important part of what influences architects, however, architects and designers are not always influenced by the same values and intentions. Value and intentions differ between different architectural movements and it also differs between different schools of architecture and schools of design as well as among individual architects and designers. One of the tools in architectural design is the floor plan. This diagram shows the relationships between rooms, spaces and other features at one level of a structure. Dimensions are usually drawn between the walls to specify room sizes and wall lengths, floor plans will also include details of fixtures like sinks, water heaters, furnaces, etc. Floor plans will include notes to specify finishes, construction methods, similar to a map in a floor plan the orientation of the view is downward from above, but unlike a conventional map, a plan is understood to be drawn at a particular vertical position. Objects below this level are seen, objects at this level are shown cut in plan-section, plan view or planform is defined as a vertical orthographic projection of an object on a horizontal plane, like a map. A plan is typically any procedure used to achieve an objective and it is a set of intended actions, through which one expects to achieve a goal. Informal or ad-hoc plans are created by individuals in all of their pursuits, building construction is the process of preparing for and forming buildings and building systems. Construction starts with planning, design, and financing and continues until the structure is ready for occupancy, far from being a single activity, large scale construction is a feat of human multitasking. Normally, the job is managed by a manager, and supervised by a construction manager, design engineer

Transparency and translucency
–
In the field of optics, transparency is the physical property of allowing light to pass through the material without being scattered. On a macroscopic scale, the photons can be said to follow Snells Law, in other words, a translucent medium allows the transport of light while a transparent medium not only allows the transport of light but allows for image formation. The opposite property of translucency is opacity, transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color. When light encounters a material, it can interact with it in different ways. These interactions depend on the wavelength of the light and the nature of the material, photons interact with an object by some combination of reflection, absorption and transmission. Some materials, such as glass and clean water, transmit much of the light that falls on them and reflect little of it. Many liquids and aqueous solutions are highly transparent, absence of structural defects and molecular structure of most liquids are mostly responsible for excellent optical transmission. Materials which do not transmit light are called opaque, many such substances have a chemical composition which includes what are referred to as absorption centers. Many substances are selective in their absorption of light frequencies. They absorb certain portions of the spectrum while reflecting others. The frequencies of the spectrum which are not absorbed are either reflected or transmitted for our physical observation and this is what gives rise to color. The attenuation of light of all frequencies and wavelengths is due to the mechanisms of absorption. Transparency can provide almost perfect camouflage for animals able to achieve it and this is easier in dimly-lit or turbid seawater than in good illumination. Many marine animals such as jellyfish are highly transparent, at the atomic or molecular level, physical absorption in the infrared portion of the spectrum depends on the frequencies of atomic or molecular vibrations or chemical bonds, and on selection rules. Nitrogen and oxygen are not greenhouse gases because there is no absorption because there is no molecular dipole moment. With regard to the scattering of light, the most critical factor is the scale of any or all of these structural features relative to the wavelength of the light being scattered. Primary material considerations include, Crystalline structure, whether or not the atoms or molecules exhibit the long-range order evidenced in crystalline solids, glassy structure, scattering centers include fluctuations in density or composition. Microstructure, scattering centers include internal surfaces such as boundaries, crystallographic defects

Relative humidity
–
Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest and it requires less water vapor to attain high relative humidity at low temperatures, more water vapour is required to attain high relative humidity in warm or hot air. Humans are sensitive to high humidity because the body uses evaporative cooling, enabled by perspiration. Perspiration evaporates from the more slowly under humid conditions than under arid. For example, if the air temperature is 24 °C and the humidity is zero percent. If the relative humidity is 100 percent at the air temperature. In other words, if the air is 24 °C and contains saturated water vapor, then the human body cools itself at the rate as it would if it were 27 °C. The heat index and the humidex are indices that reflect the effect of temperature. In cold climates, the temperature causes lower capacity for water vapour to flow about. Dry cracked skin can result from dry air, low humidity causes tissue lining nasal passages to dry, crack and become more susceptible to penetration of Rhinovirus cold viruses. Low humidity is a cause of nosebleeds. The use of a humidifier in homes, especially bedrooms, can help with these symptoms, indoor relative humidities should be kept above 30% to reduce the likelihood of the occupants nasal passages drying out. Humans can be comfortable within a range of humidities depending on the temperature—from thirty to seventy percent—but ideally between 50% and 60%. Very low humidity can create discomfort, respiratory problems, and aggravate allergies in some individuals, in the winter, it is advisable to maintain relative humidity at 30 percent or above. Extremely low relative humidities may also cause eye irritation, wooden furniture can shrink, causing the paint that covers these surfaces to fracture. When the temperature is low and the humidity is high. When relative humidity approaches 100 percent, condensation can occur on surfaces, leading to problems with mold, corrosion, decay, condensation can pose a safety risk as it can promote the growth of mold and wood rot as well as possibly freezing emergency exits shut. The basic principles for buildings, above, also apply to vehicles, in addition, there may be safety considerations

Mechanical stress
–
For example, when a solid vertical bar is supporting a weight, each particle in the bar pushes on the particles immediately below it. When a liquid is in a container under pressure, each particle gets pushed against by all the surrounding particles. The container walls and the pressure-inducing surface push against them in reaction and these macroscopic forces are actually the net result of a very large number of intermolecular forces and collisions between the particles in those molecules. Strain inside a material may arise by various mechanisms, such as stress as applied by external forces to the material or to its surface. Any strain of a material generates an internal elastic stress, analogous to the reaction force of a spring. In liquids and gases, only deformations that change the volume generate persistent elastic stress, however, if the deformation is gradually changing with time, even in fluids there will usually be some viscous stress, opposing that change. Elastic and viscous stresses are usually combined under the mechanical stress. Significant stress may exist even when deformation is negligible or non-existent, stress may exist in the absence of external forces, such built-in stress is important, for example, in prestressed concrete and tempered glass. Stress may also be imposed on a material without the application of net forces, for example by changes in temperature or chemical composition, stress that exceeds certain strength limits of the material will result in permanent deformation or even change its crystal structure and chemical composition. In some branches of engineering, the stress is occasionally used in a looser sense as a synonym of internal force. For example, in the analysis of trusses, it may refer to the total traction or compression force acting on a beam, since ancient times humans have been consciously aware of stress inside materials. Until the 17th century the understanding of stress was largely intuitive and empirical, with those tools, Augustin-Louis Cauchy was able to give the first rigorous and general mathematical model for stress in a homogeneous medium. Cauchy observed that the force across a surface was a linear function of its normal vector, and, moreover. The understanding of stress in liquids started with Newton, who provided a formula for friction forces in parallel laminar flow. Stress is defined as the force across a small boundary per unit area of that boundary, following the basic premises of continuum mechanics, stress is a macroscopic concept. In a fluid at rest the force is perpendicular to the surface, in a solid, or in a flow of viscous liquid, the force F may not be perpendicular to S, hence the stress across a surface must be regarded a vector quantity, not a scalar. Moreover, the direction and magnitude depend on the orientation of S. Thus the stress state of the material must be described by a tensor, called the stress tensor, with respect to any chosen coordinate system, the Cauchy stress tensor can be represented as a symmetric matrix of 3×3 real numbers

Mold
–
A mold or mould is a fungus that grows in the form of multicellular filaments called hyphae. In contrast, fungi that can adopt a single-celled growth habit are called yeasts, molds are a large and taxonomically diverse number of fungal species in which the growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism, the hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. Cross-walls may delimit connected compartments along the hyphae, each containing one or multiple, the dusty texture of many molds is caused by profuse production of asexual spores formed by differentiation at the ends of hyphae. The mode of formation and shape of spores is traditionally used to classify molds. Many of these spores are colored, making the much more obvious to the human eye at this stage in its life-cycle. Molds are considered to be microbes and do not form a taxonomic or phylogenetic grouping. In the past, most molds were classified within the Deuteromycota, molds cause biodegradation of natural materials, which can be unwanted when it becomes food spoilage or damage to property. They also play important roles in biotechnology and food science in the production of foods, beverages, antibiotics, pharmaceuticals. There are thousands of species of molds, which have diverse life-styles including saprotrophs, mesophiles, psychrophiles and thermophiles. They all require moisture for growth and some live in aquatic environments, like all fungi, molds derive energy not through photosynthesis but from the organic matter on which they live, utilising heterotrophy. Typically, molds secrete hydrolytic enzymes, mainly from the hyphal tips and these enzymes degrade complex biopolymers such as starch, cellulose and lignin into simpler substances which can be absorbed by the hyphae. In this way molds play a role in causing decomposition of organic material. Many molds also synthesise mycotoxins and siderophores which, together with lytic enzymes, molds can also grow on stored food for animals and humans, making the food unpalatable or toxic and are thus a major source of food losses and illness. Many strategies for food preservation are to prevent or slow growth as well as growth of other microbes. Molds reproduce by producing large numbers of spores, which may contain a single nucleus or be multinucleate. Mold spores can be asexual or sexual, many species can produce both types, other mold spores have slimy sheaths and are more suited to water dispersal. Mold spores are spherical or ovoid single cells, but can be multicellular

A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants, a characteristic that places fungi in a different kingdom from plants, bacteria and some protists, is chitin in their cell walls. Similar to animals, fungi are heterotrophs, they acquire their food by absorbing dissolved molecules, growth is their means of mobility, except for spores, which may travel through the air or water. Fungi are the principal decomposers in ecological systems and this fungal group is distinct from the structurally similar myxomycetes and oomycetes. The discipline of biology devoted to the study of fungi is known as mycology, in the past, mycology was regarded as a branch of botany, although it is now known fungi are genetically more closely related to animals than to plants. Abundant worldwide, most fungi are inconspicuous because of the size of their structures. Fungi include symbionts of plants, animals, or other fungi and they may become noticeable when fruiting, either as mushrooms or as molds. Fungi perform a role in the decomposition of organic matter and have fundamental roles in nutrient cycling. Since the 1940s, fungi have been used for the production of antibiotics, Fungi are also used as biological pesticides to control weeds, plant diseases and insect pests. Many species produce bioactive compounds called mycotoxins, such as alkaloids and polyketides, the fruiting structures of a few species contain psychotropic compounds and are consumed recreationally or in traditional spiritual ceremonies. Fungi can break down manufactured materials and buildings, and become significant pathogens of humans, losses of crops due to fungal diseases or food spoilage can have a large impact on human food supplies and local economies. The fungus kingdom encompasses a diversity of taxa with varied ecologies, life cycle strategies. However, little is known of the biodiversity of Kingdom Fungi. Advances in molecular genetics have opened the way for DNA analysis to be incorporated into taxonomy, phylogenetic studies published in the last decade have helped reshape the classification within Kingdom Fungi, which is divided into one subkingdom, seven phyla, and ten subphyla. The English word fungus is directly adopted from the Latin fungus, used in the writings of Horace, a group of all the fungi present in a particular area or geographic region is known as mycobiota, e. g. the mycobiota of Ireland. Like plants, fungi grow in soil and, in the case of mushrooms, form conspicuous fruit bodies. The fungi are now considered a kingdom, distinct from both plants and animals, from which they appear to have diverged around one billion years ago. Fungi have membrane-bound cytoplasmic organelles such as mitochondria, sterol-containing membranes and they have a characteristic range of soluble carbohydrates and storage compounds, including sugar alcohols, disaccharides, and polysaccharides

History of hide materials
–
Humanity has used animal hides since the Paleolithic, for clothing as well as mobile shelters such as tipis and wigwams, and household items. Since ancient times, hides have also used as a writing medium. Fur clothing was used by other hominids, at least the Neanderthal man, as animal husbandry was introduced during the Neolithic, human communities got a steady source of hides. The oldest known piece of footwear is the Areni-1 shoe that was made in Armenia around 3,500 BCE. Rawhide is a simple product, that turns stiff. It was formerly used for binding pieces of wood together, today it is mostly found in drum skins. Parchment for use in document was introduced during the Bronze Age and later refined into vellum, tanning of hides to manufacture leather was introduced during the Neolithic, and is documented from Ancient Egypt around 1,300 BCE. Various substances used were obtained from trees, as well as animal brains. The odor from tanning separated the tanneries from populated areas, during the Middle Ages, leather craft was developed, as turnshoes and welt shoes were invented. Refined kinds of such as suede and nubuck were also introduced. New kinds of tanning chemicals came to use during the Industrial Revolution, chromium tanning was invented during the 1850s. Patent leather has been manufactured since 1819, phenol formaldehyde resin came into use during World War II. Fur farming was introduced in the 19th century, and is today the source of fur clothing. Synthetic fur is an alternative to genuine fur, for cost, several kinds of synthetic leather have been invented during the 20th century
