Bagh Prints of Madhya Pradesh
–
Bagh Print is a traditional hand block print with natural colours, an Indian Handicraft practised in Bagh, Dhar district in Madhya Pradesh, India. Its name is derived from the village Bagh on the banks of the Bagh River, Bagh print fabric with replicated geometric and floral compositions with vegetable colours of red and black over a white background is a popular Textile printing product. Bagh Prints is listed as a geographically tagged and is protected under the Geographical Indications of Goods Act 1999 of the Government of India. It was registered by the Controller General of Patents Designs and Trademarks under the title Bagh Prints of Madhya Pradesh and recorded with tag under Application number 98 in 2008. Its logo with the titleBagh Prints of Madhya Pradesh was approved under application number 505 dated 1 August 2015 under Class 24 Textiles, the Bagh village where this handicraft is practiced lies within the geographical coordinates of 22°22′00″N 74°40′00″E at an elevation of 240 metres. The Bagh river, which flows near the village, is major factor in the adoption of Bagh Print. The Narmada river, about 30 kilometres from Bagh, which is a source, is an important source for this art work. Bagh Print, as it is known in Madhya Pradesh, was started by the community of Muslim Khatris in 1962 when they migrated from Manawar to Bagh. However, the reasons for their migration from Sindh across the Indus is not clear, in this printing technique the cloth used is cotton and silk cloth which are subject to treatment of a blend of corroded iron fillings, alum and Alizarin. The designs are patterned by skilled artisans, on completion of the printing process, the printed fabric is subject to repeated washing in the flowing waters of the river and then dried in the sun for a specific period to obtain the fine luster. The Khatri communitys migration from Sind is also said to be due to harassment by a Brahmin king, after migrating from Sindh their first settlement was Pali. Due tp a severe famine they moved to Gautampur in Malwa region, at that time a new railway line was being laid in Gautampur which made them move from Gautampur to Manawar in Nimar district in Madhya Pradesh. Ismail Khatri is the leading craftsman who migrated to Bagh village with his group in the 1960s. He then gave shape and a new approach to the printing technique which was then in practice in a rudimentary form among 80 percent of the tribal people. However, there was also an impact on this art form in the 1960s. But Ismail Khatri adhered to his technique and made many improvisations and his primary innovation was creating the Bagh Print on different types of cloth by printing on them. His innovative design of a bed cover, which he printed with his patterns, consisted of a bed cover which had 1,200 different blocks which won him the National Award in 1984. In 2011, this art form got a further boost when the BaghPrints design was adopted in a theme of the Madhya Pradesh state at the Republic Day parade in New Delhi on 26 January 2011

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Woodworking
–
Woodworking is the activity or skill of making items from wood, and includes cabinet making, wood carving, joinery, carpentry, and woodturning. Along with stone, clay and animal parts, wood was one of the first materials worked by early humans, microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials, among early finds of wooden tools are the worked sticks from Kalambo Falls, Clacton-on-Sea and Lehringen. The spears from Schöningen provide some of the first examples of hunting gear. Flint tools were used for carving, since Neolithic times, carved wooden vessels are known, for example, from the Linear Pottery culture wells at Kückhofen and Eythra. Examples of Bronze Age wood-carving include tree trunks worked into coffins from northern Germany and Denmark, there is significant evidence of advanced woodworking in Ancient Egypt. Woodworking is depicted in extant ancient Egyptian drawings, and a considerable amount of ancient Egyptian furniture has been preserved. Tombs represent a collection of these artefacts and the inner coffins found in the tombs were also made of wood. The metal used by the Egyptians for woodworking tools was originally copper and eventually, commonly used woodworking tools included axes, adzes, chisels, pull saws, and bow drills. Mortise and tenon joints are attested from the earliest Predynastic period and these joints were strengthened using pegs, dowels and leather or cord lashings. Animal glue came to be used only in the New Kingdom period, Ancient Egyptians invented the art of veneering and used varnishes for finishing, though the composition of these varnishes is unknown. Woodworking was essential to the Romans and it provided, sometimes the only, material for buildings, transportation, tools, and household items. Vitruvius dedicates a chapter of his De architectura to timber. Pliny, while not a botanist, dedicated six books of his Natural History to trees and woody plants which provides a wealth of information on trees, the progenitors of Chinese woodworking are considered to be Lu Ban and his wife Lady Yun, from the Spring and Autumn period. Lu Ban is said to have introduced the plane, chalk-line and his teachings were supposedly left behind in the book Lu Ban Jing. Despite this, it is believed that the text was written some 1500 years after his death. This book is filled largely with descriptions of dimensions for use in building various items such as pots, tables, altars, etc. It mentions almost nothing of the intricate glue-less and nail-less joinery for which Chinese furniture was so famous, with the advances in modern technology and the demands of industry, woodwork as a field has changed

Workshop
–
Beginning with the Industrial Revolution era, a workshop may be a room or building which provides both the area and tools that may be required for the manufacture or repair of manufactured goods. Workshops were the places of production until the advent of industrialization. In the 20th and 21st century, many Western homes contain a workshop in the garage, basement, home workshops typically contain a workbench, hand tools, power tools and other hardware. In some repair industries, such as locomotives and aircraft, the operations have specialized workshops called backshops or railway workshops. Most repairs are carried out in workshops, except where an industrial service is needed. Category, Railway workshops The New Yankee Workshop Laboratory Hackspace Studio

Shoe
–
A shoe is an item of footwear intended to protect and comfort the human foot while the wearer is doing various activities. Shoes are also used as an item of decoration and fashion, the design of shoes has varied enormously through time and from culture to culture, with appearance originally being tied to function. Additionally, fashion has often dictated many design elements, such as whether shoes have very high heels or flat ones, contemporary footwear in the 2010s varies widely in style, complexity and cost. Basic sandals may consist of only a sole and simple strap. High fashion shoes made by famous designers may be made of materials, use complex construction. Some shoes are designed for specific purposes, such as boots designed specifically for mountaineering or skiing, traditionally, shoes have been made from leather, wood or canvas, but in the 2010s, they are increasingly made from rubber, plastics, and other petrochemical-derived materials. Though the human foot is adapted to varied terrain and climate conditions, it is vulnerable to environmental hazards such as sharp rocks and hot ground. Some shoes are worn as safety equipment, such as steel-soled boots which are required on construction sites, the earliest known shoes are sandals dating from approximately 7000 or 8000 BC, found in the Fort Rock Cave in the US state of Oregon in 1938. Ötzi the Icemans shoes, dating to 3300 BC, featured brown bearskin bases, deerskin side panels, and a bark-string net, the Jotunheimen shoe was discovered in August 2006. Archaeologists estimate that the shoe was made between 1800 and 1100 BC, making it the oldest article of clothing discovered in Scandinavia. It is thought that shoes may have used long before this. By studying the bones of the toes, it was observed that their thickness decreased approximately 40,000 to 26,000 years ago. This led archaeologists to deduce that wearing shoes resulted in less bone growth and these earliest designs were very simple in design, often mere foot bags of leather to protect the feet from rocks, debris, and cold. They were more commonly found in colder climates, many early natives in North America wore a similar type of footwear, known as the moccasin. These are tight-fitting, soft-soled shoes typically made out of leather or bison hides, many moccasins were also decorated with various beads and other adornments. Moccasins were not designed to be waterproof, and in wet weather and warm summer months, as civilizations began to develop, thong sandals were worn. This practice dates back to pictures of them in ancient Egyptian murals from 4000 BC, One pair found in Europe was made of papyrus leaves and dated to be approximately 1,500 years old. They were also worn in Jerusalem during the first century of the Common Era, thong sandals were worn by many civilizations and made from a wide variety of materials

Shoemaking
–
Shoemaking is the process of making footwear. Originally, shoes were made one at a time by hand, shoemakers, also known as cordwainers or snobs, may produce a range of footwear items, including shoes, boots, sandals, clogs and moccasins. Such items are made of leather, wood, rubber, plastic, jute or other plant material. Trades that engage in shoemaking have included the cordwainers and cobblers trades, today shoes are often made on a factory basis rather than a craft basis. For most of history, shoemaking has been a handicraft, limited to time consuming manufacture by hand, traditional shoemakers used more than 15 different techniques of making shoes. Some of these were, pegged construction, English welted, goyser welted, Norwegian, stitchdown, turnout, German sewn, moccasin, bolognese stitched, and blake-stitched. The most basic foot protection, used since ancient times in the Mediterranean area, was the sandal, similar footwear worn in the Far East was made from plaited grass or palm fronds. In climates that required a full foot covering, a piece of untanned hide was laced with a thong, providing full protection for the foot. The production of shoes, was widespread in medieval Europe. They were made from a piece of wood roughly cut into shoe form. A variant of this form was the clog, which were wooden soles to which a leather upper was attached, the sole and heel were made from one piece of maple or ash two inches thick, and a little longer and broader than the desired size of shoe. With the use of a hollower, the inner soles contours were adapted to the shape of the foot, the leather uppers were then fitted closely to the groove around the sole. Clogs were of great advantage to workers in muddy and damp conditions, keeping the feet dry, by the 1600s, leather shoes came in two main types. Turn shoes consisted of one thin flexible sole, which was sewed to the upper while outside in and this type was used for making slippers and similar shoes. The second type united the upper with an insole, which was attached to an out-sole with a raised heel. This was the variety, and was used for most footwear, including standard shoes. The traditional shoemaker would measure the feet and cut out upper leathers according to the required size and these parts were fitted and stitched together. The insole was then attached to a last made of wood, some lasts were straight, while curved lasts came in pairs, one for left shoes, the other for right shoes

Profession
–
The term is a truncation of the term liberal profession, which is, in turn, an Anglicization of the French term profession libérale. Medieval and early modern tradition recognized only four professions, divinity, medicine, the military officer, just as some professions rise in status and power through various stages, others may decline. Disciplines formalized more recently, such as architecture, now have equally long periods of study associated with them, originally, any regulation of the professions was self-regulation through bodies such as the College of Physicians or the Inns of Court. With the growing role of government, statutory bodies have taken on this role. It may be resisted as limiting the freedom to innovate or to practice as in their professional judgement they consider best. An example was in 2008, when the British government proposed wide statutory regulation of psychologists, besides regulating access to a profession, professional bodies may set examinations of competence and enforce adherence to an ethical code. Typically, individuals are required by law to be qualified by a professional body before they are permitted to practice in that profession. However, in countries, individuals may not be required by law to be qualified by such a professional body in order to practice. This requirement is set out by the Educational Department Bureau of Hong Kong, Professions tend to be autonomous, which means they have a high degree of control of their own affairs, professionals are autonomous insofar as they can make independent judgments about their work. This usually means the freedom to exercise their professional judgement, however, it also has other meanings. Professional autonomy is often described as a claim of professionals that has to serve primarily their own interests, one major implication of professional autonomy is the traditional ban on corporate practice of the professions, especially accounting, architecture, medicine, and law. This means that in many jurisdictions, these professionals cannot do business through regular for-profit corporations, the obvious implication of this is that all equity owners of the professional business entity must be professionals themselves. This avoids the possibility of an owner of the firm telling a professional how to do his or her job. But because professional business entities are locked out of the stock market. Professions enjoy a social status, regard and esteem conferred upon them by society. This high esteem arises primarily from the social function of their work. All professions involve technical, specialized and highly skilled work often referred to as professional expertise, training for this work involves obtaining degrees and professional qualifications without which entry to the profession is barred. Updating skills through continuing education is required through training and this power is used to control its own members, and also its area of expertise and interests

Skilled worker
–
A skilled worker is any worker who has special skill, training, knowledge, and ability in their work. A skilled worker may have attended a college, university or technical school, or, a skilled worker may have learned their skills on the job. Examples of skilled labor include software development, paramedics, police officers, soldiers, physicians, crane operators, drafters, painters, plumbers, craftsmen, cooks and these workers can be either blue-collar or white-collar workers, with varied levels of training or education. In the northern region of the United States, craft unions may have served as the catalyst to ferment a strong solidarity in favor of skilled labor in the period of the Gilded Age, the Knights argued that the specialization of industrialization had undermined the bargaining power of skilled labor. The period between 1901 and 1925 signals the rise and fall of the Socialist Party of America which depended on skilled workers. Skilled workers were the heart of the movement before World War I but during the 1920s, they lost much of their enthusiasm. In the 20th century, in Nazi Germany, the class was subdivided into, agricultural workers, unskilled and semi-skilled workers, skilled craft workers, other skilled workers. After the end of World War II, West Germany surpassed France in the employment of skilled labor needed at a time when industrialization was sweeping Europe at a fast pace. West Germanys preponderance in the training of skilled workers in technical schools, was the factor to outweigh the balance between the two countries. In the first decade of the 21st century, the wage of a highly skilled machinist in the United States of America is $3,000 to $4,000 per month. In China, the wage for a factory worker is $150 a month. While most jobs require some level of skill, skilled workers bring some degree of expertise to the performance of a given job. For example, a worker who inspects new televisions for whether they turn on or off can fulfil this job with little or no knowledge of the inner workings of televisions. However, someone who repairs televisions would be considered a worker, since such a person would possess the knowledge to be able to identify. In addition to the use of the term, various agencies or governments. Such definitions can affect matters such as immigration, licensure and eligibility for travel or residency, citizenship and Immigration Services, skilled worker positions are not seasonal or temporary and require at least two years of experience or training. Skilled work varies in type, education requirements and availability, such differences are often reflected in titling, opportunity, responsibility and salary. Both skilled and non-skilled workers are vital and indispensable for the smooth-running of a free-market and/or capitalist society, generally, however, individual skilled workers are more valued to a given company than individual non-skilled workers, as skilled workers tend to be more difficult to replace

Middle Ages
–
In the history of Europe, the Middle Ages or Medieval Period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance, the Middle Ages is the middle period of the three traditional divisions of Western history, classical antiquity, the medieval period, and the modern period. The medieval period is subdivided into the Early, High. Population decline, counterurbanisation, invasion, and movement of peoples, the large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the seventh century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, although there were substantial changes in society and political structures, the break with classical antiquity was not complete. The still-sizeable Byzantine Empire survived in the east and remained a major power, the empires law code, the Corpus Juris Civilis or Code of Justinian, was rediscovered in Northern Italy in 1070 and became widely admired later in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions, monasteries were founded as campaigns to Christianise pagan Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th, the Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from Muslims. Kings became the heads of centralised nation states, reducing crime and violence, intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, and by the founding of universities. Controversy, heresy, and the Western Schism within the Catholic Church paralleled the conflict, civil strife. Cultural and technological developments transformed European society, concluding the Late Middle Ages, the Middle Ages is one of the three major periods in the most enduring scheme for analysing European history, classical civilisation, or Antiquity, the Middle Ages, and the Modern Period. Medieval writers divided history into periods such as the Six Ages or the Four Empires, when referring to their own times, they spoke of them as being modern. In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua, leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People. Bruni and later argued that Italy had recovered since Petrarchs time. The Middle Ages first appears in Latin in 1469 as media tempestas or middle season, in early usage, there were many variants, including medium aevum, or middle age, first recorded in 1604, and media saecula, or middle ages, first recorded in 1625. The alternative term medieval derives from medium aevum, tripartite periodisation became standard after the German 17th-century historian Christoph Cellarius divided history into three periods, Ancient, Medieval, and Modern. The most commonly given starting point for the Middle Ages is 476, for Europe as a whole,1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period

Goods
–
In economics, goods are materials that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product. A common distinction is made between goods that are property, and services, which are non-physical. A good is an item that is useful to people but scarce in relation to its demand. In contrast, free goods, such as air, are naturally in abundant supply, commodities may be used as a synonym for economic goods but often refer to marketable raw materials and primary products. Although in economic theory all goods are considered tangible, in reality certain classes of goods, such as information, only take intangible forms. For example, among other goods an apple is an object, while news belongs to an intangible class of goods. Goods may increase or decrease their utility directly or indirectly and may be described as having marginal utility, some things are useful, but not scarce enough to have monetary value, such as the Earths atmosphere, these are referred to as free goods. In economics, a bad is the opposite of a good, Goods diversity allows for their classification into different categories based on distinctive characteristics, such as tangibility and relative elasticity. A tangible good like an apple differs from a good like information due to the impossibility of a person to physically hold the latter. Intangible goods differ from services in that goods are transferable and can be traded. Price elasticity also differentiates types of goods, an inelastic good is one for which there are few or no substitutes, such as tickets to major sporting events, original works by famous artists, and prescription medicine such as insulin. Complementary goods are generally more inelastic than goods in a family of substitutes and this is because hamburger buns and beef are complementary goods. It is important to note that goods considered complements or substitutes are relative associations, the following chart illustrates the classification of goods according to their exclusivity and competitiveness. Goods are capable of being delivered to a consumer. Goods that are economic intangibles can only be stored, delivered, Goods, both tangibles and intangibles, may involve the transfer of product ownership to the consumer. Services do not normally involve transfer of ownership of the service itself, for example, distributing electricity among consumers is a service provided by an electric utility company. While the service is a process that remains in its entirety in the ownership of the service provider. The consumer becomes electric energy owner by purchase and may use it for any lawful purposes just like any other goods, fast-moving consumer goods Final goods Intangible asset Intangible good List of economics topics Goods and services Service Tangible property Bannock, Graham et al

Maintenance, repair and operations
–
Maintenance, repair, and operations involves fixing any sort of mechanical, plumbing, or electrical device should it become out of order or broken. In the former case it may be an operation within a larger organization or smaller operation. The former of these represents a closed loop supply chain and usually has the scope of maintenance, repair, the latter of the categorisations is an open loop supply chain and is typified by refurbishment and remanufacture. The main characteristic of the loop system is that the demand for a product is matched with the supply of a used product. Neglecting asset write-offs and exceptional activities the total population of the product between the customer and the service provider remains constant, for material – all action taken to retain material in a serviceable condition or to restore it to serviceability. It includes inspection, testing, servicing, classification as to serviceability, repair, rebuilding, for material – all supply and repair action taken to keep a force in condition to carry out its mission. For material – the routine recurring work required to keep a facility in such condition that it may be used, at its original or designed capacity. Manufacturers and industrial-supply companies often refer to MRO as opposed to original equipment manufacturer, OEM includes any activity related to the direct manufacture of goods, where MRO refers to any maintenance, repair or overhaul activity to keep a manufacturing plant or facility running. Maintenance is strictly connected to the stage of ideation, in which the concept of maintainability must be included, overhaul extends to the concept of improving performance over and above original design specification. Corrective maintenance where equipment is repaired or replaced after wear, malfunction or break down, preventive maintenance is maintenance performed with the intent of avoiding failures, safety violations, unnecessary production costs and losses, and to conserve original materials of fabrication. The effectiveness of a maintenance schedule depends on the RCM analysis which it was based on

Artisan
–
Artisans practice a craft and may through experience and aptitude reach the expressive levels of an artist. The adjective artisanal is sometimes used in describing hand-processing in what is viewed as an industrial process. Thus, artisanal is sometimes used in marketing and advertising as a word to describe or imply some relation with the crafting of handmade food products, such as bread. Many of these have traditionally been handmade, rural or pastoral goods but are now commonly made on a larger scale with automated mechanization in factories. Artisans were the dominant producers of products prior to the Industrial Revolution. In ancient Greece, artisans were drawn to agoras and often built workshops nearby, during the Middle Ages, the term artisan was applied to those who made things or provided services. It did not apply to unskilled manual labourers, Artisans were divided into two distinct groups, those who operated their own businesses and those who did not. Those who owned their businesses were called masters, while the latter were the journeymen, one misunderstanding many people have about this social group is that they picture them as workers in the modern sense, employed by someone. The most influential group among the artisans were the masters, the business owners, the owners enjoyed a higher social status in their communities. Shokunin is a Japanese word for artisan or craftsman, which implies a pride in ones own work. In the words of shokunin Tashio Odate, Shokunin means not only having technical skill, a social obligation to work his best for the general welfare of the people, obligation both material and spiritual.

Urban centers
–
An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, in urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment. The worlds urban population in 1950 of just 746 million has increased to 3.9 billion in the decades since, in 2009, the number of people living in urban areas surpassed the number living in rural areas and since then the world has become more urban than rural. This was the first time that the majority of the population lived in a city. In 2014 there were 7.25 billion people living on the planet, Urban areas are created and further developed by the process of urbanization. Urban areas are measured for various purposes, including analyzing population density, historian John Gurda writes, I have tried to uncover Milwaukees civic bedrock - the shifting foundation on which individuals have built their lives and the community has constructed its identity. There is no doubt that the deepest layer of bedrock is economic. In every age, people have chosen to live in areas not because of their climates or landmarks or cultural attractions. It was economic opportunity that brought people to Milwaukee, and it is economic opportunity that keeps them there, I define cities as concentrations of people animated by concentrations of capital. More simply put, money is the root of all cities, official definitions vary somewhat between nations. The ten largest metropolitan areas account for half of the population, about 3 million people live in Buenos Aires City and the Greater Buenos Aires metropolitan area totals around 13 million, making it one of the largest urban areas in the world. The metropolitan areas of Córdoba, Rosario, Mendoza and Tucumán have around 1.3 million inhabitants each and La Plata, seven other provinces have over one million people each, Mendoza, Tucumán, Entre Ríos, Salta, Chaco, Corrientes and Misiones. According to IBGE urban areas already concentrate 84. 35% of the population, while the Southeast region remains the most populated one, with over 80 million inhabitants. The largest metropolitan areas in Brazil are São Paulo, Rio de Janeiro, and Belo Horizonte — all in the Southeastern Region — with 20,12, and 5 million inhabitants respectively. The majority of state capitals are the largest cities in their states, except for Vitória, the capital of Espírito Santo, and Florianópolis, there are also non-capital metropolitan areas in the states of São Paulo, Minas Gerais, Rio Grande do Sul and Santa Catarina. According to Statistics Canada, an area in Canada is an area with a population of at least 1,000 people where the density is no fewer than 400 persons per square kilometre. If two or more areas are within 2 km of each other by road, they are merged into a single urban area. Accordingly, the new definition set out three types of population centres, small, medium and large

Guild
–
A guild /ɡɪld/ is an association of artisans or merchants who control the practice of their craft in a particular town. The earliest types of guild were formed as confraternities of tradesmen and they were organized in a manner something between a professional association, trade union, a cartel, and a secret society. A lasting legacy of traditional guilds are the guildhalls constructed and used as meeting places, an important result of the guild framework was the emergence of universities at Bologna, Oxford and Paris, they originated as guilds of students as at Bologna, or of masters as at Paris. Usually the founders were free independent master craftsmen who hired apprentices, there were several types of guilds, including the two main categories of merchant guilds and craft guilds but also the frith guild and religious guild. In many cases became the governing body of a town. The Freedom of the City, effective from the Middle Ages until 1835, gave the right to trade, Trade guilds arose in the 14th century as craftsmen united to protect their common interest. The occasion for these oaths were drunken banquets held on December 26, gregory of Tours tells a miraculous tale of a builder whose art and techniques suddenly left him, but were restored by an apparition of the Virgin Mary in a dream. Michel Rouche remarks that the story speaks for the importance of practically transmitted journeymanship, in France, guilds were called corps de métiers. According to Viktor Ivanovich Rutenburg, Within the guild itself there was little division of labour. Thus, according to Étienne Boileaus Book of Handicrafts, by the century there were no less than 100 guilds in Paris. In Catalan towns, specially at Barcelona, guilds or gremis were a basic agent in the society, a shoemakers guild is recorded in 1208. In England, specifically in the City of London Corporation, more than 110 guilds, referred to as companies, survive today. Other groups, such as the Worshipful Company of Tax Advisers, have been formed far more recently, membership in a livery company is expected for individuals participating in the governance of The City, as the Lord Mayor and the Remembrancer. The guild system reached a state in Germany circa 1300 and held on in German cities into the 19th century. In the 15th century, Hamburg had 100 guilds, Cologne 80, the latest guilds to develop in Western Europe were the gremios of Spain, e. g. Valencia or Toledo. Not all city economies were controlled by guilds, some cities were free, in order to become a Master, a Journeyman would have to go on a three-year voyage called Journeyman years. The practice of the Journeyman years still exists in Germany and France, in Ghent, as in Florence, the woolen textile industry developed as a congeries of specialized guilds. The appearance of the European guilds was tied to the emergent money economy, before this time it was not possible to run a money-driven organization, as commodity money was the normal way of doing business

Trade
–
Trade, or commerce, involves the transfer of goods or services from one person or entity to another, often in exchange for money. A network that allows trade is called a market, the original form of trade, barter, saw the direct exchange of goods and services for other goods and services. Barter is trading things without the use of money, later one side of the barter started to involve precious metals, which gained symbolic as well as practical importance. Modern traders generally negotiate through a medium of exchange, such as money, as a result, buying can be separated from selling, or earning. The invention of money greatly simplified and promoted trade, Trade between two traders is called bilateral trade, while trade between more than two traders is called multilateral trade. Trade exists due to the specialization and division of labor, in which most people concentrate on an aspect of production. As such, trade at prices between locations can benefit both locations. Trade originated with human communication in prehistoric times, trading was the main facility of prehistoric people, who bartered goods and services from each other before the innovation of modern-day currency. Peter Watson dates the history of commerce from circa 150,000 years ago. In the Mediterranean region the earliest contact between cultures were of members of the species Homo sapiens principally using the Danube river, at a time beginning 35–30,000 BCE, Trade is believed to have taken place throughout much of recorded human history. There is evidence of the exchange of obsidian and flint during the stone age, Trade in obsidian is believed to have taken place in Guinea from 17,000 BCE. The earliest use of obsidian in the Near East dates to the Lower, Trade in the stone age was investigated by Robert Carr Bosanquet in excavations of 1901. Trade is believed to have first begun in south west Asia, obsidian was traded at distances of 900 kilometres within the Mediterranean region. Trade in the Mediterranean during the Neolithic of Europe was greatest in this material, networks were in existence at around 12,000 BCE Anatolia was the source primarily for trade with the Levant, Iran and Egypt according to Zarins study of 1990. Melos and Lipari sources produced among the most widespread trading in the Mediterranean region as known to archaeology, the Sari-i-Sang mine in the mountains of Afghanistan was the largest source for trade of Lapis Lazuli. The material was most largely traded during the Kassite period of Babylonia beginning 1595 BCE, ebla was a prominent trading centre during the third millennia, with a network reaching into Anatolia and north Mesopotamia. Materials used for creating jewelry were traded with Egypt since 3000 BCE, long-range trade routes first appeared in the 3rd millennium BCE, when Sumerians in Mesopotamia traded with the Harappan civilization of the Indus Valley. The Phoenicians were noted sea traders, traveling across the Mediterranean Sea, for this purpose they established trade colonies the Greeks called emporia

Education
–
Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, Education frequently takes place under the guidance of educators, but learners may also educate themselves. Education can take place in formal or informal settings and any experience that has an effect on the way one thinks, feels. The methodology of teaching is called pedagogy, in most regions education is compulsory up to a certain age. Etymologically, the education is derived from the Latin ēducātiō from ēducō which is related to the homonym ēdūcō from ē-. Education began in prehistory, as trained the young in the knowledge. In pre-literate societies this was achieved orally and through imitation, story-telling passed knowledge, values, and skills from one generation to the next. As cultures began to extend their knowledge beyond skills that could be learned through imitation. Schools existed in Egypt at the time of the Middle Kingdom, plato founded the Academy in Athens, the first institution of higher learning in Europe. The city of Alexandria in Egypt, established in 330 BCE, there, the great Library of Alexandria was built in the 3rd century BCE. European civilizations suffered a collapse of literacy and organization following the fall of Rome in CE476, after the Fall of Rome, the Catholic Church became the sole preserver of literate scholarship in Western Europe. The church established cathedral schools in the Early Middle Ages as centres of advanced education, some of these establishments ultimately evolved into medieval universities and forebears of many of Europes modern universities. During the High Middle Ages, Chartres Cathedral operated the famous, founded in 1088, the University of Bologne is considered the first, and the oldest continually operating university. The Renaissance in Europe ushered in a new age of scientific and intellectual inquiry and appreciation of ancient Greek, around 1450, Johannes Gutenberg developed a printing press, which allowed works of literature to spread more quickly. The European Age of Empires saw European ideas of education in philosophy, religion, arts, the Enlightenment saw the emergence of a more secular educational outlook in Europe. In most countries today, full-time education, whether at school or otherwise, is compulsory for all children up to a certain age, formal education occurs in a structured environment whose explicit purpose is teaching students. Usually, formal education takes place in a environment with classrooms of multiple students learning together with a trained, certified teacher of the subject. Most school systems are designed around a set of values or ideals that govern all educational choices in that system, such choices include curriculum, organizational models, design of the physical learning spaces, student-teacher interactions, methods of assessment, class size, educational activities, and more

Peasantry
–
A peasant is a member of a traditional class of farmers, either laborers or owners of small farms, especially in the Middle Ages under feudalism, or more generally, in any pre-industrial society. In Europe, peasants were divided into three classes according to their status, slave, serf, and free tenant. Peasants either hold title to land in fee simple, or hold land by any of several forms of tenure, among them socage, quit-rent, leasehold. The implication of the term is that the peasant is uneducated, ignorant, the word peasant is also commonly used in a non-pejorative sense as a collective noun for the rural population in the poor and under-developed countries of the world. The word peasant is derived from the 15th century French word païsant, meaning one from the pays, or countryside, ultimately from the Latin pagus, Peasants typically made up the majority of the agricultural labour force in a pre-industrial society. The majority of the people in the Middle Ages were peasants, more generally, the word peasant is sometimes used to refer pejoratively to those considered to be lower class, perhaps defined by poorer education and/or a lower income. The open field system of agriculture dominated most of northern Europe during medieval times, under this system, peasants lived on a manor presided over by a lord or a bishop of the church. Peasants paid rent or labor services to the lord in exchange for their right to cultivate the land, fallowed land, pastures, forests, and wasteland were held in common. The open field system required cooperation among the peasants of the manor and it was gradually replaced by individual ownership and management of land. This process happened in a pronounced and truncated way in Eastern Europe. Lacking any catalysts for change in the 14th century, Eastern European peasants largely continued upon the original medieval path until the 18th and 19th centuries, even before emancipation in 1861, serfdom was on the wane in Russia. The proportion of serfs within the empire had decreased from 45-50 percent at the end of the eighteenth century. In Germany, peasants continued to center their lives in the well into the 19th century. They belonged to a body and helped to manage the community resources. In the East they had the status of serfs bound permanently to parcels of land, a peasant is called a Bauer in German and Bur in Low German. In most of Germany, farming was handled by tenant farmers who paid rents, Peasant leaders supervised the fields and ditches and grazing rights, maintained public order and morals, and supported a village court which handled minor offenses. Inside the family the patriarch made all the decisions, and tried to arrange marriages for his children. Much of the communal life centered on church services and holy days

Agriculture
–
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of human civilization. The study of agriculture is known as agricultural science, the history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology, genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. Agricultural food production and water management are increasingly becoming global issues that are fostering debate on a number of fronts, the major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include cereals, vegetables, fruits, oils, meats, fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo, other useful materials are also produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental products such as cut flowers and nursery plants. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, field, Agriculture usually refers to human activities, although it is also observed in certain species of ant, termite and ambrosia beetle. To practice agriculture means to use resources to produce commodities which maintain life, including food, fiber, forest products, horticultural crops. This definition includes arable farming or agronomy, and horticulture, all terms for the growing of plants, even then, it is acknowledged that there is a large amount of knowledge transfer and overlap between silviculture and agriculture. In traditional farming, the two are often combined even on small landholdings, leading to the term agroforestry, Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin, wild grains were collected and eaten from at least 105,000 years ago. Pigs were domesticated in Mesopotamia around 15,000 years ago, rice was domesticated in China between 13,500 and 8,200 years ago, followed by mung, soy and azuki beans. Sheep were domesticated in Mesopotamia between 13,000 and 11,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Cattle were domesticated from the aurochs in the areas of modern Turkey. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca, llamas, alpacas, sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago, cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia at an unknown time

Pottery
–
Pottery is the craft of making ceramic material into pots or potterywares using mud. Major types of potterywares include earthenware, stoneware and porcelain, the place where such wares are made by a potter is also called a pottery. Early Neolithic pottery have found in places such as Jomon Japan. A clay body can be decorated before or after firing, however, prior to shaping processes. Kneading helps to ensure an even moisture content throughout the body, air trapped within the clay body needs to be removed. This is called de-airing and can be accomplished either by a called a vacuum pug or manually by wedging. Wedging can also produce an even moisture content. Once a clay body has been kneaded and de-aired or wedged, after shaping, it is dried and then fired. Clay ware takes on varying physical characteristics during the making of pottery, at sufficient moisture content, bodies at this stage are in their most plastic form. Leather-hard refers to a body that has been dried partially. At this stage the clay object has approximately 15% moisture content, clay bodies at this stage are very firm and only slightly pliable. Trimming and handle attachment often occurs at the leather-hard state, bone-dry refers to clay bodies when they reach a moisture content at or near 0%. It is now ready to be bisque fired, bisque refers to the clay after the object is shaped to the desired form and fired in the kiln for the first time, known as bisque fired or biscuit fired. This firing changes the body in several ways. Mineral components of the body will undergo chemical changes that will change the colour of the clay. Glaze fired is the stage of some pottery making. A glaze may be applied to the form and the object can be decorated in several ways. After this the object is glazed fired, which causes the material to melt

Village
–
A village is a clustered human settlement or community, larger than a hamlet but smaller than a town, with a population ranging from a few hundred to a few thousand. Though often located in areas, the term urban village is also applied to certain urban neighbourhoods. Villages are normally permanent, with fixed dwellings, however, transient villages can occur, further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement. In the past, villages were a form of community for societies that practise subsistence agriculture. In Great Britain, a hamlet earned the right to be called a village when it built a church, in many cultures, towns and cities were few, with only a small proportion of the population living in them. The Industrial Revolution attracted people in numbers to work in mills and factories. This also enabled specialization of labor and crafts, and development of many trades, the trend of urbanization continues, though not always in connection with industrialization. Although many patterns of life have existed, the typical village was small. Homes were situated together for sociability and defence, and land surrounding the living quarters was farmed, Traditional fishing villages were based on artisan fishing and located adjacent to fishing grounds. The soul of India lives in its villages, declared M. K. Gandhi at the beginning of 20th century, according to the 2011 census of India,68. 84% of Indians live in 640,867 different villages. The size of these villages varies considerably,236,004 Indian villages have a population of fewer than 500, while 3,976 villages have a population of 10, 000+. Most of the villages have their own temple, mosque, or church, auyl is a Kazakh word meaning village in Kazakhstan. According to the 2009 census of Kazakhstan,42. 7% of Kazakhs live in 8172 different villages, to refer to this concept along with the word auyl often used the slavic word selo in Northern Kazakhstan. Peoples Republic of China In mainland China, villages 村 are divisions under township Zh, 乡 or town Zh, Republic of China In the Republic of China, villages are divisions under townships or county-controlled cities. The village is called a tsuen or cūn under a rural township, japan South Korea In Indonesia, depending on the principles they are administered, villages are called Kampung or Desa. A Desa is administered according to traditions and customary law, while a kelurahan is administered along more modern principles, Desa are generally located in rural areas while kelurahan are generally urban subdivisions. A village head is respectively called kepala desa or lurah, both are elected by the local community. A desa or kelurahan is the subdivision of a kecamatan, in turn the subdivision of a kabupaten or kota, the same general concept applies all over Indonesia
21.
Apprenticeship
–
An apprenticeship is a system of training a new generation of practitioners of a trade or profession with on-the-job training and often some accompanying study. Apprenticeship also enables practitioners to gain a license to practice in a regulated profession, Apprenticeships typically last 3 to 7 years. People who successfully complete an apprenticeship reach the journeyman or professional level of competence. In early modern usage, the clipped form prentice was common, the system of apprenticeship first developed in the later Middle Ages and came to be supervised by craft guilds and town governments. A master craftsman was entitled to employ young people as a form of labour in exchange for providing food, lodging. Most apprentices were males, but female apprentices were found in such as seamstress, tailor. Apprentices usually began at ten to fifteen years of age, in Coventry those completing seven-year apprenticeships with stuff merchants were entitled to become freemen of the city. Subsequently, governmental regulation and the licensing of technical colleges and vocational education formalized and bureaucratized the details of apprenticeship, Australian Apprenticeships encompass all apprenticeships and traineeships. They cover all sectors in Australia and are used to achieve both entry-level and career upskilling objectives. There were 470,000 Australian Apprentices in-training as at 31 March 2012, Australian Government employer and employee incentives may be applicable, while State and Territory Governments may provide public funding support for the training element of the initiative. Australian Apprenticeships combine time at work with formal training and can be full-time, part-time or school-based, Australian Apprentice and Traineeship services are dedicated to promoting retention, therefore much effort is made to match applicants with the right apprenticeship or traineeship. This is done with the aid of aptitude tests, tips, information and resources on potential apprenticeship and traineeship occupations are available in over sixty industries. The distinction between the terms apprentices and trainees lies mainly around traditional trades and the time it takes to gain a qualification, Australia also has a fairly unusual safety net in place for businesses and Australian Apprentices with its Group Training scheme. It is a safety net, because the Group Training Organisation is the employer and provides continuity of employment and it lasts two to four years – the duration varies among the 250 legally recognized apprenticeship trades. About 40 percent of all Austrian teenagers enter apprenticeship training upon completion of compulsory education and this number has been stable since the 1950s. The five most popular trades are, Retail Salesperson, Clerk, Car Mechanic, Hairdresser, there are many smaller trades with small numbers of apprentices, like EDV-Systemtechniker which is completed by fewer than 100 people a year. The Apprenticeship Leave Certificate provides the apprentice with access to two different vocational careers, the person responsible for overseeing the training inside the company is called Lehrherr or Ausbilder. An Ausbilder must prove he has the qualifications needed to educate another person
22.
Journeyman
–
A journeyman is a skilled worker who has successfully completed an official apprenticeship qualification in a building trade or craft. They are considered competent and authorized to work in that field as a qualified employee. A journeyman earns their license through education, supervised experience, although a journeyman has completed a trade certificate and is able to work as an employee, they are not yet able to work as a self-employed master craftsman. The term journeyman was originally used in the trade guilds. Journeymen were paid each day, and this is where the word ‘journey’ derived from- journée meaning ‘a day’ in French, each individual guild generally recognized three ranks of workers, apprentices, journeymen, and masters. A journeyman, as a qualified tradesman could become a master, guidelines were put in place to promote responsible tradesmen who were held accountable for their own work, and to protect the individual trade and the general public from unskilled workers. To become a master, a journeyman has to submit a master piece of work to a guild for an evaluation, only after evaluation can a journeyman be admitted to the guild as a master. Sometimes, a journeyman is required to accomplish a three-year working trip, the word journeyman comes from the French word journée, which means a days work or a days travel, journée in turn comes from Vulgar Latin, diurnum meaning day. The title refers to the right to charge a fee for each days work. A journeyman has completed an apprenticeship but is employed by such as a master craftsman. A journeyman could not employ others, carpenters in Germany have retained the tradition of traveling journeymen even today, although only a few still practice it. In France, wandering journeymen were known as compagnons, in modern apprenticeship systems, a journeyman is a person who has a trades certificate that shows the required completion of an apprenticeship. In many countries this is the highest formal rank and allows them to all the tasks of the trade within the area where they are certified, to supervise apprentices. The modern apprenticeship system aims to build skills through on the job training, an apprentice is able to earn a living while learning these new skills. The working environment is linked to the employer giving the individual company the opportunity to shape the apprentice, within the guidelines. Quite often a working relationship is built between employee and employer. A person who has completed the traditional live-in apprenticeship could be considered a journeyman, the journeyman license certifies that the craftsman has met the requirements of time in the field and time in an approved classroom setting. A journeyman has the responsibility of supervising workers of lesser experience and training as them, a journeyman is commonly expected to have a wide range of experience, covering most fields of his trade
23.
Master craftsman
–
A master craftsman or master tradesman was a member of a guild. In the European guild system, only masters and journeymen were allowed to be members of the guild, an aspiring master would have to pass through the career chain from apprentice to journeyman before he could be elected to become a master craftsman. He would then have to produce a sum of money and a masterpiece before he could join the guild. If the masterpiece was not accepted by the masters, he was not allowed to join the guild, originally, holders of the academic degree of Master of Arts were also considered, in the Medieval universities, as master craftsmen in their own academic field. The Guild of Master Craftsmen continues a tradition established by the guilds of medieval Europe, the earliest of these were frith or peace guilds - groups bonded together for mutual protection following the breakdown of the kins, which were groups related by blood ties. The world-renowned College of Arms in London awarded the coat of arms of The Guild of Master Craftsmen in 1992, the southern keep of Lewes Castle, which overlooks the Guild’s headquarters, is featured above the helmet as the crest. While guilds as such do not exist, many trades continue the apprentice-journeyman-master model, carpenters, electricians, pipefitters and plumbers are notable examples. The terms Master Mariner and harbormaster reflect the fact that the holders of positions were originally Master craftsman in the Seamens Guild. Further derived from harbormaster is stationmaster, though no longer existed when railways came into being. In Germany, the craftsman is the highest professional qualification in crafts and is a state-approved grade. The qualification includes theoretical and practical training in the craft as well as business, additionally, it implies the qualification to train apprentices. These qualifications prepare the Meister for running their own business or alternatively for higher positions at a company, the status of master craftsmen is regulated in the German Gesetz zur Ordnung des Handwerks. While privileged guilds have been abolished in Germany, the ranks of apprentice, journeyman, for security-relevant crafts, e. g. electricians and chimney sweeps, any business in the trade has to be run by a master craftsman or has to employ at least one Meister. Journeymen and master craftsmen are by law members of their regional chamber of crafts. The chamber organizes vocational training and oversees the examination of the journeymen, if these requirements are fulfilled, the candidate can take courses for the Meisterprüfung. The duration of the courses takes 4 to 6 years depending on the craft, the examination includes theoretical, practical and oral parts and takes 5 to 7 days. In some crafts, the creation of a masterpiece is also part of the examination, the German Meister qualifies the holder to study for a bachelors degree at University, whether the Meister holds a regular university entrance qualification or not. According to the German Qualifications Framework, the Meisterbrief is at the level as a bachelors degree, even though it is not an academic degree

Industrial Revolution
–
The Industrial Revolution was the transition to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. The Industrial Revolution began in Great Britain and most of the important technological innovations were British, aided by these legal and cultural foundations, an entrepreneurial spirit and consumer revolution drove industrialisation in Britain, which would be emulated in countries around the world. A change in marrying patterns to getting married later made able to accumulate more human capital during their youth. The Industrial Revolution marks a turning point in history, almost every aspect of daily life was influenced in some way. In particular, average income and population began to exhibit unprecedented sustained growth, mechanised textile production spread from Great Britain to continental Europe in the early 19th century, with important centres of textiles, iron and coal emerging in Belgium, and later in France. Since then industrialisation has spread throughout much of the world, the precise start and end of the Industrial Revolution is still debated among historians, as is the pace of economic and social changes. Economic historians are in agreement that the onset of the Industrial Revolution is the most important event in the history of humanity since the domestication of animals and plants. The term Industrial Revolution applied to change was becoming more common by the late 1830s. Friedrich Engels in The Condition of the Working Class in England in 1844 spoke of an industrial revolution, however, although Engels wrote in the 1840s, his book was not translated into English until the late 1800s, and his expression did not enter everyday language until then. Credit for popularising the term may be given to Arnold Toynbee, some historians, such as John Clapham and Nicholas Crafts, have argued that the economic and social changes occurred gradually and the term revolution is a misnomer. This is still a subject of debate among some historians, the commencement of the Industrial Revolution is closely linked to a small number of innovations, beginning in the second half of the 18th century. By the 1830s the following gains had been made in important technologies, Textiles – mechanised cotton spinning powered by steam or water greatly increased the output of a worker, the power loom increased the output of a worker by a factor of over 40. The cotton gin increased productivity of removing seed from cotton by a factor of 50, large gains in productivity also occurred in spinning and weaving of wool and linen, but they were not as great as in cotton. Steam power – the efficiency of steam engines increased so that they used between one-fifth and one-tenth as much fuel, the adaptation of stationary steam engines to rotary motion made them suitable for industrial uses. The high pressure engine had a power to weight ratio. Steam power underwent an expansion after 1800. Iron making – the substitution of coke for charcoal greatly lowered the fuel cost for pig iron, using coke also allowed larger blast furnaces, resulting in economies of scale. The cast iron blowing cylinder was first used in 1760 and it was later improved by making it double acting, which allowed higher furnace temperatures
25.
Mass production
–
Mass production, flow production or continuous production is the production of large amounts of standardized products, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods, the term mass production was popularized by a 1926 article in the Encyclopedia Britannica supplement that was written based on correspondence with Ford Motor Company. The New York Times used the term in the title of an article that appeared before publication of the Britannica article, the concepts of mass production are applied to various kinds of products, from fluids and particulates handled in bulk to discrete solid parts to assemblies of such parts. Mass production is a field, but it can generally be contrasted with craft production or distributed manufacturing. Mass production of fluid matter typically involves pipes with centrifugal pumps or screw conveyors to transfer raw materials or partially complete products between vessels, materials on pallets are handled with forklifts. Also used for handling heavy items like reels of paper, steel or machinery are electric overhead cranes, sometimes called bridge cranes because they span large factory bays. Mass production is intensive and energy intensive, as it uses a high proportion of machinery. It is also usually automated while total expenditure per unit of product is decreased, however, the machinery that is needed to set up a mass production line is so expensive that there must be some assurance that the product is to be successful to attain profits. One of the descriptions of mass production is that the skill is built into the tool, for example, in the 19th or early 20th century, this could be expressed as the craftsmanship is in the workbench itself. Later, once computerized control came about, jigs were obviated and this is the specialized capital required for mass production, each workbench and set of tools is different. Crossbows made with bronze parts were produced in China during the Warring States period, the Qin Emperor unified China at least in part by equipping large armies with these weapons, which were equipped with a sophisticated trigger mechanism made of interchangeable parts. Ships of war were produced on a scale at a moderate cost by the Carthaginians in their excellent harbors. The Venetians themselves also produced ships using prefabricated parts and assembly lines many centuries later, the Venetian Arsenal apparently produced nearly one ship every day, in what was effectively the worlds first factory which, at its height, employed 16,000 people. Mass production in the industry has been commonplace since the Gutenberg Bible was published using a printing press in the mid-15th century. In the Industrial Revolution simple mass production techniques were used at the Portsmouth Block Mills in England to make ships pulley blocks for the Royal Navy in the Napoleonic Wars. It was achieved in 1803 by Marc Isambard Brunel in cooperation with Henry Maudslay under the management of Sir Samuel Bentham, the Navy was in a state of expansion that required 100,000 pulley blocks to be manufactured a year. Bentham had already achieved remarkable efficiency at the docks by introducing power-driven machinery, by 1805, the dockyard had been fully updated with the revolutionary, purpose-built machinery at a time when products were still built individually with different components. A total of 45 machines were required to perform 22 processes on the blocks, the machines were almost entirely made of metal thus improving their accuracy and durability

Industry
–
Industry is the production of goods or related services within an economy. The major source of revenue of a group or company is the indicator of its relevant industry, when a large group has multiple sources of revenue generation, it is considered to be working in different industries. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and this came through many successive rapid advances in technology, such as the production of steel and coal. Following the Industrial Revolution, possibly a third of the economic output are derived that is from manufacturing industries. Many developed countries and many developing/semi-developed countries depend significantly on manufacturing industry, Industries, the countries they reside in, and the economies of those countries are interlinked in a complex web of interdependence. Industries can be classified in a variety of ways, at the top level, industry is often classified according to the three-sector theory into sectors, primary, secondary, and tertiary. Some authors add quaternary or even quinary sectors, over time, the fraction of a societys industry within each sector changes. Below the economic sectors there are other more detailed industry classifications. These classification systems commonly divide industries according to functions and markets. Market-based classification systems such as the Global Industry Classification Standard and the Industry Classification Benchmark are used in finance, the International Standard Industrial Classification of all economic activities is the most complete and systematic industrial classification made by the United Nations Statistics Division. ISIC is a classification of economic activities arranged so that entities can be classified according to the activity they carry out. The Industrial Revolution led to the development of factories for large-scale production, originally the factories were steam-powered, but later transitioned to electricity once an electrical grid was developed. The mechanized assembly line was introduced to parts in a repeatable fashion. This led to significant increases in efficiency, lowering the cost of the end process, later automation was increasingly used to replace human operators. This process has accelerated with the development of the computer and the robot, historically certain manufacturing industries have gone into a decline due to various economic factors, including the development of replacement technology or the loss of competitive advantage. An example of the former is the decline in manufacturing when the automobile was mass-produced. A recent trend has been the migration of prosperous, industrialized nations towards a post-industrial society and this is manifested by an increase in the service sector at the expense of manufacturing, and the development of an information-based economy, the so-called informational revolution. In a post-industrial society, manufacturing is relocated to more favourable locations through a process of off-shoring

Built environment
–
In social science, the term built environment refers to the man-made surroundings that provide the setting for human activity, ranging in scale from buildings to parks. It has been defined as the space in which people live, work. The built environment encompasses places and spaces created or modified by people including buildings, parks, in recent years, public health research has expanded the definition of built environment to include healthy food access, community gardens, mental health, walkability and bikeability. The effort was in partnership with others who believed that beautifying American cities would improve the moral compass of the cities and this beautification process included parks and architectural design. For example, community forest user group in Nepal is multidimensional institution, in public health, built environment refers to physical environments that are designed with health and wellness as integral parts of the communities. Research has indicated that the way neighborhoods are created can affect both the activity and mental health of the communities’ residents. Studies have shown that built environments that were designed to improve physical activity are linked to higher rates of physical activity. Neighborhoods with more walkability had lower rates of obesity as well as increased physical activity among its residents and they also had lower rates of depression, higher social capital, and less alcohol abuse. Walkability features in these neighborhoods include safety, sidewalk construction, as well as destinations in which to walk, in addition, the perception of a walkable neighborhood, one that is perceived to have good sidewalks and connectivity, is correlated with higher rates of physical activity. Assessments of walkability have been completed through the use of GIS programs and this example of a walkability assessment tool determines distances to grocery stores and other amenities, as well as connectivity and intersection frequency using specific addresses. Assessments such as the Street Smart Walk Score can be utilized by city, public health also addresses additional components of built environments including “bikeability” and healthy food access such as proximity to grocery stores and community gardens. Bikeability refers to the access that an area has granted to safe biking through multiple bike paths, both walkability and bikeability have been cited as determinants of physical activity. Access to healthy food is also an important component of the built environment, a higher density of convenience stores has been associated with obesity in children. In contrast, improved access to community supermarkets and farmer’s markets is correlated with lower overweight status, specifically in low income neighborhoods, the presence of a local grocery store is correlated with lower BMI/overweight risk. Community gardens are considered a part of the built environment. The intersection of health with other disciplines is evident in the design process of built environments which includes environmental planning, policy development. Research suggests that people are active in mixed-use communities or those that incorporate retail and residential. Those who preferred to walk and live in walkable environments often have lower obesity rates, in landscape architecture, the built environment is understood to mean a human-made landscape, as distinguished from the natural environment, for example, a city park is a built environment

Metalsmith
–
A metalsmith or simply smith is a craftsman fashioning useful items out of various metals. Smithing is one of the oldest metalworking occupations, shaping metal with a hammer is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge, smithing can also involve the other aspects of metalworking, such as refining metals from their ores, casting it into shapes, and filing to shape and size. The prevalence of metalworking in the culture of recent centuries has led Smith, as a suffix, -smith connotes a meaning of a specialized craftsman—for example, wordsmith and tunesmith are nouns synonymous with writer or songwriter, respectively. In pre-industrialized times, smiths held high or special social standing since they supplied the tools needed for farming. This was especially true in some West African cultures, a metalsmith is one who works with or has the knowledge and the capacity of working with all metals. Today, this tool is still used by blacksmiths as it was traditionally. The term, metalsmith, often refers to artisans and craftpersons who practice their craft in many different metals, including gold, machinists are metalsmiths who produce high-precision parts and tools. The most advanced of these tools, CNC machines, are computer controlled and largely automated

Agra
–
Agra is a city on the banks of the river Yamuna in the northern state of Uttar Pradesh, India. It is 378 kilometres west of the capital, Lucknow,206 kilometres south of the national capital New Delhi and 125 kilometres north of Gwalior. Agra is one of the most populous cities in Uttar Pradesh, Agra is a major tourist destination because of its many splendid Mughal-era buildings, most notably the Tāj Mahal, Agra Fort and Fatehpūr Sikrī, all three of which are UNESCO World Heritage Sites. Agra falls within the Braj cultural region, the city was first mentioned in the epic Mahābhārata, where it was called Agrevaṇa. Legend ascribes the founding of the city to Raja Badal Singh, however, the 11th century Persian poet Masūd Sad Salmān writes of a desperate assault on the fortress of Agra, then held by the Shāhī King Jayapala, by Sultan Mahmud of Ghazni. It was mentioned for the first time in 1080 AD when a Ghaznavide force captured it, Sultan Sikandar Lodī was the first to move his capital from Delhi to Agra in 1506. He governed the country from here and Agra assumed the importance of the second capital. He died in 1517 and his son, Ibrāhīm Lodī, remained in there for nine more years and several palaces, wells. Finally being defeated at the Battle of Panipat in 1526, between 1540 and 1556, Afghans, beginning with Sher Shah Suri ruled the area. It achieved fame as the capital of the Mughal Empire from 1556 to 1658, Agra features a semiarid climate that borders on a humid subtropical climate. The city features mild winters, hot and dry summers and a monsoon season, however the monsoons, though substantial in Agra, are not quite as heavy as the monsoon in other parts of India. This is a factor in Agra featuring a semiarid climate as opposed to a humid subtropical climate. As of 2011 India census, Agra city has a population of 1,585,704, the urban agglomeration of Agra has a population of 1,760,285. Males constitute 53% of the population and females 47%, Agra city has an average literacy rate of 73. 11%, lower than the national average of 74%. Literacy rate of males is considerably higher than that of women, the sex ratio in the city was 875 females per thousand males while child sex ratio stood at 857. Agra district literacy rate is 62. 56%, Agra is dominated by Yadavs and Jats. According to the 2011 census, Agra district has a population of 4,380,793 and this gives it a ranking of 41st in India. The district has a density of 1,084 inhabitants per square kilometre

Scooter (motorcycle)
–
A scooter or motor scooter is a motorcycle with step-through frame and a platform for the riders feet. Elements of scooter design have been present in some of the earliest motorcycles, Scooter development continued in Europe and the United States between the World Wars. The global popularity of scooters dates from the post-World War II introductions of the Vespa and these scooters were intended to provide low-power personal transportation. The original layout is widely used in this application. Maxi-scooters, with engines from 250 to 850 cc have been developed for Western markets, scooters are popular for personal transport, partly due to being cheap to buy, easy to operate and convenient to park and store. Licensing requirements for scooters are easier and cheaper than for cars in most parts of the world, a motor scooter is a motorcycle similar to a kick scooter with a seat, a floorboard, and small or low wheels. The United States Department of Transportation defines a scooter as a motorcycle that has a platform for the feet or has integrated footrests. The classic scooter design features a frame and a flat floorboard for the riders feet. This design is possible because most scooter engines and drive systems are attached to the axle or under the seat. Scooters usually feature bodywork, including a front leg shield and body that conceals all or most of the mechanicals, there is often some integral storage space, either under the seat, built into the front leg shield, or both. Scooters have varying engine displacements and configurations ranging from 50 cc single-cylinder to 850 cc twin-cylinder models, some scooters carry a spare wheel. Many recent scooters use conventional front forks with the front axle fastened at both ends, most jurisdictions do not differentiate between scooters and motorcycles. For all legal purposes in the United States of America, the National Highway Traffic Safety Administration recommends using the motorcycle for all of these vehicles. However, while NHTSA excludes the term motor scooter from legal definition, it proceeds, in the same document, the emissions of mopeds and scooters have been the subject of multiple studies. In the same study, four-stroke mopeds, with and without catalytic converters, approximate parity with automobiles was achieved with NOx emissions in these studies. Emissions performance was tested on a basis and was unaffected by fuel economy. Scooter-like traits began to develop in motorcycle designs around the 1900s, in 1894, Hildebrand & Wolfmüller produced the first motorcycle that was available for purchase. Their motorcycle had a frame, with its fuel tank mounted on the down tube, its parallel two-cylinder engine mounted low on the frame

Handicraft
–
One of the worlds oldest handicraft is Dhokra, this is a sort of metal casting has been used in India for over 4,000 years and is still used. Collective terms for handicrafts include artisanry, handicrafting, crafting, many handicrafters use natural, even entirely indigenous, materials while others may prefer modern, non-traditional materials, and even upcycle industrial materials. The individual artisanship of an item is the paramount criterion. Most crafts require the development of skill and the application of patience, like folk art, handicraft output often has cultural and/or religious significance, and increasingly may have a political message as well, as in craftivism. The Arts and Crafts movement originated as a late 19th-century design reform and social movement principally in Europe, North America and Australia and this was held up in contrast to what was perceived to be the alienating effects of industrial labor. These activities were called crafts because originally many of them were professions under the guild system, adolescents were apprenticed to a master craftsman, and refined their skills over a period of years in exchange for low wages. Simple arts and crafts projects are an elementary and middle school activity in both mainstream and alternative education systems around the world. e. The use of traditional handicrafting techniques by professional fine artists, many community centers and schools run evening or day classes and workshops, for adults and children, offering to teach basic craft skills in a short period of time. If sold, they are sold in Direct sales, Gift shops, Public markets, in developing countries, handicrafts are sold to locals and as Souvenirs to tourists. Sellers tend to speak at least a few words of common tourist languages

Tradition
–
A tradition is a belief or behavior passed down within a group or society with symbolic meaning or special significance with origins in the past. Common examples include holidays or impractical but socially meaningful clothes, there are about 150 new traditions made each year. Traditions can persist and evolve for thousands of years—the word tradition itself derives from the Latin tradere or traderer literally meaning to transmit, to hand over, to give for safekeeping. While it is assumed that traditions have ancient history, many traditions have been invented on purpose, whether that be political or cultural. Various academic disciplines also use the word in a variety of ways, one way tradition is used more simply, often in academic work but elsewhere also, is to indicate the quality of a piece of information being discussed. For example, According to tradition, Homer was born on Chios and this tradition may never be proven or disproven. In another example, King Arthur, by tradition a true British king, has inspired many well loved stories, of course whether they are documented fact or not does not decrease their value as cultural history and literature. Aside from this use in describing the quality of information, various scholarly fields define the term differently, for example, anthropology and biology have each defined tradition it more precisely than in conventional, as described below, in order to facilitate scholarly discourse. The concept of tradition, as the notion of holding on to a time, is also found in political and philosophical discourse. For example, it is the basis of the concept of traditionalism. In artistic contexts, tradition is used to decide the correct display of an art form, for example, in the performance of traditional genres, adherence to guidelines dictating how an art form should be composed are given greater importance than the performers own preferences. A number of factors can exacerbate the loss of tradition, including industrialization, globalization, in response to this, tradition-preservation attempts have now been started in many countries around the world, focusing on aspects such as traditional languages. Tradition is usually contrasted with the goal of modernity and should be differentiated from customs, conventions, laws, norms, routines, rules and similar concepts. The English word tradition comes from the Latin traditio, the noun from the verb traderere or tradere, it was used in Roman law to refer to the concept of legal transfers. As with many other terms, there are many definitions of tradition. Tradition can also refer to beliefs or customs that are Prehistoric, with lost or arcane origins, originally, traditions were passed orally, without the need for a writing system. Tools to aid this process include poetic devices such as rhyme, the stories thus preserved are also referred to as tradition, or as part of an oral tradition. Even such traditions, however, are presumed to have originated at some point, Traditions are often presumed to be ancient, unalterable, and deeply important, though they may sometimes be much less natural than is presumed

Craft production
–
Craft production is the process of manufacturing by hand with or without the aid of tools. In the craft manufacturing process, the product is unique. While the product may be of high quality, the uniqueness can be detrimental as seen in the case of early automobiles. Womack, Jones and Roos in the book The Machine That Changed the World detailed that early automobiles were craft produced, because each vehicle was unique, replacement parts had to be manufactured from scratch or at least customized to fit a specific vehicle. The advent of Mass production and the standardization of replacement parts guaranteed a parts compatibility with a variety of vehicle models, Mass production has many drawbacks to craft production, including that production quality can be lower than a craft-produced item. For example, in some automobile manufacturing facilities, craftsmen rework flawed, mass-produced vehicles to give the appearance of a quality product. Lean manufacturing aims to bring back or exceed the quality of craft production, craft production is a part of the informal economy in many cities, such as Istanbul, Turkey where the informal craft economy is a vital source of income for the Turkish craftspeople. Craft markets are highly dependent on interactions, and verbal training which results in variations in the goods produced. Often, the economy consists of craft neighbourhoods, by which a community is structured on the craft activity present in the area. Often used in the household, many craft goods such as historic Muman Pottery in Korea, changes in the craft economies have often coincided with changes in household organization, and social transformations, as in Korea in the Early to Middle Mumun Period. The production of crafts have a high technical demand, and therefore require full-time specialization of the skill-set in the form of workshops, or verbal. The verbal interaction between teacher and student encourages strong social bonds, which leads to cohesive communities, typical of modern day craft communities. Craft economies are highly related to place, craft-specialization explores how portable goods are integral to the social relations of a community, and links groups of people together through the creation of tangible items. Places where craft economic activity is taking place indicate strong linkages between sociopolitical organization and societal complexity and these communities are often tight-knit, with strong linkages to materials produced and sold, as well as mutual respect for fellow tradesmen in the market place.

Arts and Crafts movement
–
It stood for traditional craftsmanship using simple forms, and often used medieval, romantic, or folk styles of decoration. It advocated economic and social reform and was essentially anti-industrial and it had a strong influence on the arts in Europe until it was displaced by Modernism in the 1930s, and its influence continued among craft makers, designers, and town planners long afterwards. It was inspired by the ideas of architect Augustus Pugin, writer John Ruskin, the movement developed earliest and most fully in the British Isles, and spread across the British Empire and to the rest of Europe and North America. It was largely a reaction against the perceived impoverished state of the arts at the time. The Arts and Crafts style emerged from the attempt to reform design, but it was as much a movement of social reform as design reform and its leading practitioners did not separate the two. The art historian Nikolaus Pevsner has said that exhibits in the Great Exhibition showed ignorance of basic need in creating patterns. Owen Jones, for example, declared that Ornament, fiona MacCarthy says that unlike later zealots like Gandhi, William Morris had no practical objections to the use of machinery per se so long as the machines produced the quality he needed. Morriss followers also had differing views or changed their minds over time. C. R. Ashbee, for example, a figure in the Arts and Crafts Movement. At the time of his Guild of Handicraft, initiated in 1888, he said, We do not reject the machine, but we would desire to see it mastered. Morris insisted that the artist should be a working by hand and advocated a society of free craftspeople. Because craftsmen took pleasure in their work, he wrote, the Middle Ages was a period of greatness in the art of the common people. The treasures in our museums now are only the common used in households of that age. Medieval art was the model for much Arts and Crafts design and medieval life, before capitalism, the founders of the Arts and Crafts Exhibition Society did not insist that the designer should also be the maker. Peter Floud, writing in the 1950s, said that The founders of the Society, never executed their own designs, but invariably turned them over to commercial firms. The Arts and Crafts Movement was associated with socialist ideas in the persons of Morris, T. J. Cobden Sanderson, Walter Crane, Ashbee, in the early 1880s Morris was spending more of his time on socialist propaganda than on designing and making. Ashbee established a community of craftsmen, the Guild of Handicraft, in east London and those adherents who were not socialists, for example, Alfred Hoare Powell, advocated a more humane and personal relationship between employer and employee. Lewis Foreman Day, a successful and influential Arts and Crafts designer, was not a socialist either

Decorative arts
–
The decorative arts are arts or crafts concerned with the design and manufacture of beautiful objects that are also functional. It includes interior design, but not usually architecture, the decorative arts are often categorized in opposition to the fine arts, namely, painting, drawing, photography, and large-scale sculpture, which generally have no function other than to be seen. The distinction between the decorative and the arts has essentially arisen from the post-Renaissance art of the West. This distinction is less meaningful when considering the art of other cultures and periods. For example, Islamic art in many periods and places consists entirely of the arts, often using geometric and plant forms. The distinction between decorative and fine arts is not very useful for appreciating Chinese art, and neither is it for understanding Early Medieval art in Europe, large-scale wall-paintings were much less regarded, crudely executed, and rarely mentioned in contemporary sources. They were probably seen as a substitute for mosaic, which for this period must be viewed as a fine art. The term ars sacra is sometimes used for medieval Christian art done in metal, ivory, textiles, illuminated manuscripts have a much higher survival rate, especially in the hands of the church, as there was little value in the materials and they were easy to store. Most European art during the Middle Ages had been produced under a different set of values. The lower status given to works of art in contrast to fine art narrowed with the rise of the Arts and Crafts Movement. This aesthetic movement of the half of the 19th century was born in England and inspired by William Morris. The movement represented the beginning of an appreciation of the decorative arts throughout Europe. Many converts, both professional artists ranks and from among the intellectual class as a whole, helped spread the ideas of the movement. The influence of the Arts and Crafts Movement led to the arts being given a greater appreciation and status in society. Until the enactment of the Copyright Act 1911 only works of art had been protected from unauthorised copying. The 1911 Act extended the definition of a work to include works of artistic craftsmanship

Sculpture
–
Sculpture is the branch of the visual arts that operates in three dimensions. It is one of the plastic arts, a wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or molded, or cast. However, most ancient sculpture was painted, and this has been lost. Those cultures whose sculptures have survived in quantities include the cultures of the ancient Mediterranean, India and China, the Western tradition of sculpture began in ancient Greece, and Greece is widely seen as producing great masterpieces in the classical period. During the Middle Ages, Gothic sculpture represented the agonies and passions of the Christian faith, the revival of classical models in the Renaissance produced famous sculptures such as Michelangelos David. Relief is often classified by the degree of projection from the wall into low or bas-relief, high relief, sunk-relief is a technique restricted to ancient Egypt. Relief sculpture may also decorate steles, upright slabs, usually of stone, techniques such as casting, stamping and moulding use an intermediate matrix containing the design to produce the work, many of these allow the production of several copies. The term sculpture is used mainly to describe large works. The very large or colossal statue has had an enduring appeal since antiquity, another grand form of portrait sculpture is the equestrian statue of a rider on horse, which has become rare in recent decades. The smallest forms of life-size portrait sculpture are the head, showing just that, or the bust, small forms of sculpture include the figurine, normally a statue that is no more than 18 inches tall, and for reliefs the plaquette, medal or coin. Sculpture is an important form of public art, a collection of sculpture in a garden setting can be called a sculpture garden. One of the most common purposes of sculpture is in form of association with religion. Cult images are common in cultures, though they are often not the colossal statues of deities which characterized ancient Greek art. The actual cult images in the innermost sanctuaries of Egyptian temples, of which none have survived, were rather small. The same is true in Hinduism, where the very simple. Some undoubtedly advanced cultures, such as the Indus Valley civilization, appear to have had no monumental sculpture at all, though producing very sophisticated figurines, the Mississippian culture seems to have been progressing towards its use, with small stone figures, when it collapsed. Other cultures, such as ancient Egypt and the Easter Island culture, from the 20th century the relatively restricted range of subjects found in large sculpture expanded greatly, with abstract subjects and the use or representation of any type of subject now common. Today much sculpture is made for intermittent display in galleries and museums, small sculpted fittings for furniture and other objects go well back into antiquity, as in the Nimrud ivories, Begram ivories and finds from the tomb of Tutankhamun

Wood
–
Wood is a porous and fibrous structural tissue found in the stems and roots of trees, and other woody plants. It is a material, a natural composite of cellulose fibers which are strong in tension embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, in a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots, Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. In 2005, the stock of forests worldwide was about 434 billion cubic meters. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy, in 1991 approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction, a 2011 discovery in the Canadian province of New Brunswick discovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago. Wood can be dated by carbon dating and in species by dendrochronology to make inferences about when a wooden object was created. People have used wood for millennia for many purposes, primarily as a fuel or as a material for making houses, tools, weapons, furniture, packaging, artworks. Constructions using wood date back ten thousand years, buildings like the European Neolithic long house were made primarily of wood. Recent use of wood has changed by the addition of steel. The year-to-year variation in tree-ring widths and isotopic abundances gives clues to the climate at that time. This process is known as growth, it is the result of cell division in the vascular cambium, a lateral meristem. These cells then go on to form thickened secondary cell walls, composed mainly of cellulose, hemicellulose, if the distinctiveness between seasons is annual, these growth rings are referred to as annual rings. Where there is little seasonal difference growth rings are likely to be indistinct or absent, if the bark of the tree has been removed in a particular area, the rings will likely be deformed as the plant overgrows the scar. It is usually lighter in color than that near the portion of the ring. The outer portion formed later in the season is known as the latewood or summerwood. However, there are differences, depending on the kind of wood
38.
Clay
–
Clay is a fine-grained natural rock or soil material that combines one or more clay minerals with traces of metal oxides and organic matter. Geologic clay deposits are composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to water content and become hard, brittle. Depending on the content in which it is found, clay can appear in various colours from white to dull grey or brown to deep orange-red. Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size, silts, which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays. There is, however, some overlap in size and other physical properties. The distinction between silt and clay varies by discipline, geologists and soil scientists usually consider the separation to occur at a particle size of 2 µm, sedimentologists often use 4–5 μm, and colloid chemists use 1 μm. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils Atterberg limits, ISO14688 grades clay particles as being smaller than 2 μm and silt particles as being larger. These solvents, usually acidic, migrate through the rock after leaching through upper weathered layers. In addition to the process, some clay minerals are formed through hydrothermal activity. There are two types of deposits, primary and secondary. Primary clays form as residual deposits in soil and remain at the site of formation, secondary clays are clays that have been transported from their original location by water erosion and deposited in a new sedimentary deposit. Clay deposits are associated with very low energy depositional environments such as large lakes. Depending on the source, there are three or four main groups of clays, kaolinite, montmorillonite-smectite, illite, and chlorite. Chlorites are not always considered to be a clay, sometimes being classified as a group within the phyllosilicates. There are approximately 30 different types of clays in these categories. Varve is clay with visible annual layers, which are formed by deposition of those layers and are marked by differences in erosion. This type of deposit is common in glacial lakes

Ceramic
–
A ceramic is an inorganic, non-metallic, solid material comprising metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds. This article gives an overview of ceramic materials from the point of view of materials science, the crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified, and often completely amorphous. Most often, fired ceramics are either vitrified or semi-vitrified as is the case with earthenware, stoneware, varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators. With such a range of possible options for the composition/structure of a ceramic, the breadth of the subject is vast. Many composites, such as fiberglass and carbon fiber, while containing ceramic materials, are not considered to be part of the ceramic family. The earliest ceramics made by humans were pottery objects or figurines made from clay, either by itself or mixed with materials like silica, hardened, sintered. Later ceramics were glazed and fired to create smooth, colored surfaces, decreasing porosity through the use of glassy, ceramics now include domestic, industrial and building products, as well as a wide range of ceramic art. In the 20th century, new materials were developed for use in advanced ceramic engineering. The word ceramic comes from the Greek word κεραμικός, of pottery or for pottery, from κέραμος, potters clay, tile, the earliest known mention of the root ceram- is the Mycenaean Greek ke-ra-me-we, workers of ceramics, written in Linear B syllabic script. The word ceramic may be used as an adjective to describe a material, product or process, or it may be used as a noun, either singular, or, more commonly, as the plural noun ceramics. A ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride or carbide material, some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, weak in shearing and they withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramics generally can withstand high temperatures, such as temperatures that range from 1,000 °C to 1,600 °C. Glass is often not considered a ceramic because of its amorphous character. However, glassmaking involves several steps of the process and its mechanical properties are similar to ceramic materials. Traditional ceramic raw materials include minerals such as kaolinite, whereas more recent materials include aluminium oxide. The modern ceramic materials, which are classified as advanced ceramics, include silicon carbide, both are valued for their abrasion resistance, and hence find use in applications such as the wear plates of crushing equipment in mining operations. Advanced ceramics are used in the medicine, electrical, electronics industries. Crystalline ceramic materials are not amenable to a range of processing

Glass
–
Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. The most familiar, and historically the oldest, types of glass are silicate glasses based on the chemical compound silica, the primary constituent of sand. The term glass, in usage, is often used to refer only to this type of material. Many applications of silicate glasses derive from their optical transparency, giving rise to their use as window panes. Glass can be coloured by adding metallic salts, and can also be painted and printed with vitreous enamels and these qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures, because glass can be formed or moulded into any shape, it has been traditionally used for vessels, bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also used for paperweights, marbles. Some objects historically were so commonly made of glass that they are simply called by the name of the material, such as drinking glasses. Porcelains and many polymer thermoplastics familiar from everyday use are glasses and these sorts of glasses can be made of quite different kinds of materials than silica, metallic alloys, ionic melts, aqueous solutions, molecular liquids, and polymers. For many applications, like glass bottles or eyewear, polymer glasses are a lighter alternative than traditional glass, silica is a common fundamental constituent of glass. In nature, vitrification of quartz occurs when lightning strikes sand, forming hollow, fused quartz is a glass made from chemically-pure SiO2. It has excellent resistance to shock, being able to survive immersion in water while red hot. However, its high melting-temperature and viscosity make it difficult to work with, normally, other substances are added to simplify processing. One is sodium carbonate, which lowers the transition temperature. The soda makes the glass water-soluble, which is undesirable, so lime, some magnesium oxide. The resulting glass contains about 70 to 74% silica by weight and is called a soda-lime glass, soda-lime glasses account for about 90% of manufactured glass. Most common glass contains other ingredients to change its properties, lead glass or flint glass is more brilliant because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index, iron can be incorporated into glass to absorb infrared energy, for example in heat absorbing filters for movie projectors, while cerium oxide can be used for glass that absorbs UV wavelengths

Textile
–
A textile or cloth is a flexible material consisting of a network of natural or artificial fibres. Yarn is produced by spinning raw fibres of wool, flax, cotton, hemp, Textiles are formed by weaving, knitting, crocheting, knotting, or felting. The words fabric and cloth are used in textile assembly trades as synonyms for textile, however, there are subtle differences in these terms in specialized usage. Textile refers to any material made of interlacing fibres, a fabric is a material made through weaving, knitting, spreading, crocheting, or bonding that may be used in production of further goods. Cloth may be used synonymously with fabric but is often a piece of fabric used for a specific purpose. The word textile is from Latin, from the adjective textilis, meaning woven, from textus, the word cloth derives from the Old English clað, meaning a cloth, woven or felted material to wrap around one, from Proto-Germanic kalithaz. The discovery of dyed flax fibres in a cave in the Republic of Georgia dated to 34,000 BCE suggests textile-like materials were made even in prehistoric times. The production of textiles is a craft whose speed and scale of production has been altered almost beyond recognition by industrialization, however, for the main types of textiles, plain weave, twill, or satin weave, there is little difference between the ancient and modern methods. Textiles have an assortment of uses, the most common of which are for clothing and for such as bags. In the household they are used in carpeting, upholstered furnishings, window shades, towels, coverings for tables, beds, and other flat surfaces, in the workplace they are used in industrial and scientific processes such as filtering. Textiles are used in traditional crafts such as sewing, quilting. Textiles for industrial purposes, and chosen for other than their appearance, are commonly referred to as technical textiles. Technical textiles include textile structures for applications, medical textiles, geotextiles, agrotextiles. In all these applications stringent performance requirements must be met, woven of threads coated with zinc oxide nanowires, laboratory fabric has been shown capable of self-powering nanosystems using vibrations created by everyday actions like wind or body movements. Fashion designers commonly rely on textile designs to set their fashion collections apart from others, armani, the late Gianni Versace, and Emilio Pucci can be easily recognized by their signature print driven designs. Textiles can be made from many materials and these materials come from four main sources, animal, plant, mineral, and synthetic. In the past, all textiles were made from natural fibres, including plant, animal, in the 20th century, these were supplemented by artificial fibres made from petroleum. Textiles are made in various strengths and degrees of durability, from the finest gossamer to the sturdiest canvas, microfibre refers to fibres made of strands thinner than one denier
