Basketmaker culture
–
The Basketmaker culture of the pre-Ancestral Puebloans began about 1500 BC and continued until about AD500 with the beginning of the Pueblo I Era. The prehistoric American southwestern culture was named Basketmaker for the number of baskets found at archaeological sites of 3,000 to 2,000 years ago. Well-preserved mummies found in dry caves provide insight into the ancient Basketmakers, women were about 5 feet tall and men were 3 to 4 inches taller. They had long, narrow faces and medium to stocky build and their skin varied from light to dark brown and they had brown or black hair and eyes. Fancy hairstyles were worn by men and infrequently by women. The Basketmakers wore sandals made of yucca fibers or strips of leaves. There is little evidence of clothing aside from a few found at archaeological sites. Women may have worn aprons on special occasions, hides or blankets made of yucca fibers and rabbit fur were likely for warmth. Both men and women wore necklaces, bracelets and pendants made of shell, stone, bone, shells, such as abalone, conus and olivella from the coast of the Pacific ocean, would have been obtained through trade. In the Early Basketmaker II Era people lived a semi-nomadic hunter-gatherer lifestyle with the introduction of cultivation of corn, some of the early people lived in cave shelters in the San Juan River drainage. Excavation of their sites yielded a number of baskets, for which they received their name, corn. It was not until the Late Basketmaker II Era that people lived in permanent dwellings, crude pit-houses made of brush, logs, hunting became much easier during the Basketmaker III Era when bow-and-arrow technology replaced the spear used since the Archaic period of the Americas. Throughout the Ancestral Puebloan cultural eras the most important resource was water, in the lowlands the climate was an arid land of juniper and sage. At about 6,000 feet in elevation the climate was a land of pinyon trees. The cultural groups of this include, Ancestral Puebloans - southern Utah, southern Colorado, northern Arizona and northern. Mogollon - southeastern Arizona, southern New Mexico and northern Mexico, patayan - western Arizona, California and Baja California.

Lucy Telles
–
Lucy Parker Telles was a Mono Lake Paiute - Kucadikadi and Southern Sierra Miwok Native American basket weaver. Lucy Telles was born near Mono Lake, in Mono County and her Indian name was Pamahas, which translates to Meadows in the Northern Paiute language. Her parents were Louisa and Mack Tom and her maternal grandparents were Mono Lake Paiute Captain Sam and Mono Yosemite Paiute Susie Sam. She and her family lived in Yosemite Valley and at Mono Lake, as a child, Telles played near Galen Clarks cabin. To supplement her familys income, she caught fish in the Valley to sell to hotel keepers, Telles first husband was Jack Parker, a Paiute. In 1902 they had a son, Lloyd Parker, but shortly after he was born and she later married John Telles, a Mexican-American from Texas. John worked as a driver and laborer for the Yosemite Park & Curry Company. Lucy Telles was one of a group of Mono-Paiute women that became known for their fine, visually stunning. Other basket weaving artists in this group included Nellie Charlie and Carrie Bethel, Telles, who learned basket weaving as a child, was well known for her fine basketry during her lifetime. Her innovations in basket weaving had a influence on Yosemites weavers. While traditional Miwok baskets had one color, she used two colors per baskets and she created black from bracken fern root and red from split redbud twigs. She created new designs, some inspired by Plains Indian geometric beadwork. Lucy sold her baskets to Yosemite visitors, by the 1920s, Telles was regarded as the best basket weaver in Yosemite Valley. In 1924, she won a prize of $100 for her baskets and her most famous basket was the largest known to have been woven in Yosemite Valley. It sold for $250 in 1939, an enormous basket with a 36 diameter that took her four years to weave took first prize at the 1933 Worlds Fair. In 1950, Telles raffled off this basket, her son won it, Lucy demonstrated basket making to park visitors from 1930 until her death in 1955 or 1956. She taught her grandsons wife, Julia Peter Parker how to weave baskets and she was one of the most prolific California and Yosemite – Mono Lake Paiute basket makers. Several of her baskets are featured at the Yosemite National Park Indian museum, one of her baskets from the collection of the California Academy of Sciences, is currently on exhibit at the California Museum in Sacramento

Yosemite National Park
–
Yosemite National Park is a national park spanning portions of Tuolumne, Mariposa and Madera counties in Northern California. The park, which is managed by the National Park Service, on average, about 4 million people visit Yosemite each year, and most spend the majority of their time in the seven square miles of Yosemite Valley. The park set a record in 2016, surpassing 5 million visitors for the first time in its history. Almost 95% of the park is designated wilderness, Yosemite was central to the development of the national park idea. First, Galen Clark and others lobbied to protect Yosemite Valley from development, Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The park has a range from 2,127 to 13,114 feet and contains five major vegetation zones, chaparral/oak woodland, lower montane forest, upper montane forest, subalpine zone. Of Californias 7,000 plant species, about 50% occur in the Sierra Nevada, there is suitable habitat for more than 160 rare plants in the park, with rare local geologic formations and unique soils characterizing the restricted ranges many of these plants occupy. The geology of the Yosemite area is characterized by granitic rocks, about 10 million years ago, the Sierra Nevada was uplifted and then tilted to form its relatively gentle western slopes and the more dramatic eastern slopes. The uplift increased the steepness of stream and river beds, resulting in formation of deep, about one million years ago, snow and ice accumulated, forming glaciers at the higher alpine meadows that moved down the river valleys. Ice thickness in Yosemite Valley may have reached 4,000 feet during the early glacial episode, the downslope movement of the ice masses cut and sculpted the U-shaped valley that attracts so many visitors to its scenic vistas today. The name Yosemite originally referred to the name of a tribe which was driven out of the area by the Mariposa Battalion. Before then the area was called Ahwahnee by indigenous people, as revealed by archeological finds, the Yosemite Valley has been inhabited for nearly 3,000 years, though humans may have first visited the area as long as 8,000 to 10,000 years ago. The indigenous natives called themselves the Ahwahneechee, meaning dwellers in Ahwahnee and they are related to the Northern Paiute and Mono tribes. Many tribes visited the area to trade, including nearby Central Sierra Miwoks, a major trading route went over Mono Pass and through Bloody Canyon to Mono Lake, just to the east of the Yosemite area. Vegetation and game in the region were similar to that present today, acorns were a staple to their diet, as well as seeds and plants, salmon. In 1851 as part of the Mariposa Wars intended to suppress Native American resistance and he was pursuing forces of around 200 Ahwahneechee led by Chief Tenaya. Accounts from this battalion were the first well-documented reports of ethnic Europeans entering Yosemite Valley, attached to Savages unit was Dr. Lafayette Bunnell, the company physician, who later wrote about his awestruck impressions of the valley in The Discovery of the Yosemite. Bunnell is credited with naming Yosemite Valley, based on his interviews with Chief Tenaya, Bunnell wrote that Chief Tenaya was the founder of the Pai-Ute Colony of Ah-wah-nee

Cameroon
–
Cameroon, officially the Republic of Cameroon, is a country in Central Africa. It is bordered by Nigeria to the west, Chad to the northeast, the Central African Republic to the east, and Equatorial Guinea, Gabon, Cameroons coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. French and English are the languages of Cameroon. The country is referred to as Africa in miniature for its geological and cultural diversity. Natural features include beaches, deserts, mountains, rainforests, the country is well known for its native styles of music, particularly makossa and bikutsi, and for its successful national football team. Early inhabitants of the territory included the Sao civilisation around Lake Chad, portuguese explorers reached the coast in the 15th century and named the area Rio dos Camarões, which became Cameroon in English. Fulani soldiers founded the Adamawa Emirate in the north in the 19th century, Cameroon became a German colony in 1884 known as Kamerun. After World War I, the territory was divided between France and the United Kingdom as League of Nations mandates, the Union des Populations du Cameroun political party advocated independence, but was outlawed by France in the 1950s, leading to the Cameroonian Independence War. It waged war on French and UPC militant forces until 1971, in 1960, the French-administered part of Cameroon became independent as the Republic of Cameroun under President Ahmadou Ahidjo. The southern part of British Cameroons federated with it in 1961 to form the Federal Republic of Cameroon, the federation was abandoned in 1972. The country was renamed the United Republic of Cameroon in 1972, Cameroon enjoys relatively high political and social stability. This has permitted the development of agriculture, roads, railways, nevertheless, large numbers of Cameroonians live in poverty as subsistence farmers. Power lies firmly in the hands of the president since 1982, Paul Biya. The English-speaking territories of Cameroon have grown increasingly alienated from the government, politicians and civil society in English-speaking regions have called for greater decentralization and even complete separation or independence from the former French-governed territories. The territory of present-day Cameroon was first settled during the Neolithic Era, the longest continuous inhabitants are groups such as the Baka. From here, Bantu migrations into eastern, southern, and central Africa are believed to have originated about 2,000 years ago, the Sao culture arose around Lake Chad c. AD500 and gave way to the Kanem and its successor state, kingdoms, fondoms, and chiefdoms arose in the west. Portuguese sailors reached the coast in 1472 and they noted an abundance of the ghost shrimp Lepidophthalmus turneranus in the Wouri River and named it Rio dos Camarões, which became Cameroon in English

Bamboo
–
The bamboos /bæmˈbuː/ are evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. The dicotyledonous woody xylem is also absent, the absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 91 cm within a 24-hour period, giant bamboos are the largest members of the grass family. Bamboos are of economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source. Bamboo has a higher compressive strength than wood, brick, or concrete. The word bamboo comes from the Kannada term bambu, which was introduced to English through Indonesian, the subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae. The woody bamboos do not form a group, instead. Altogether, more than 1,400 species are placed in 115 genera, most bamboo are native to warm and moist tropical and warm temperate climates. However, many species are found in climates, from hot tropical regions to cool mountainous regions. In the Asia-Pacific region they occur across East Asia, from 50°N latitude in Sakhalin south to Northern Australia, and west to India, China, Japan, Korea, India, and Australia, all have several endemic populations. They also occur in numbers in sub-Saharan Africa, confined to tropical areas, from southern Senegal in the north to southern Mozambique. Bamboo is also native through Central America and Mexico, northward into the Southeastern United States, canada and continental Europe is not known to have any native species of bamboo. Recently, some attempts have been made to grow bamboo on a basis in the Great Lakes region of east-central Africa. In the United States, several companies are growing, harvesting, bamboos include some of the fastest-growing plants on Earth, with reported growth rates up to 91 cm in 24 hours. Primarily growing in regions of warmer climates during the late Cretaceous period, some of the largest timber bamboo can grow over 30 m tall, and be as large as 25–30 cm in diameter. However, the range for mature bamboo is species-dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4. 6–12 m, depending on species

Bangalore
–
Bangalore /bæŋɡəˈlɔːr/, officially known as Bengaluru, is the capital of the Indian state of Karnataka. It has a population of about 8.42 million and a population of about 8.52 million, making it the third most populous city. It is located in southern India on the Deccan Plateau and its elevation is over 900 m above sea level, the highest of Indias major cities. In 1638, the Marāthās conquered and ruled Bangalore for almost 50 years, after which the Mughals captured and it was captured by the British after victory in the Fourth Anglo-Mysore War, who returned administrative control of the city to the Maharaja of Mysore. The old city developed in the dominions of the Maharaja of Mysore and was capital of the Princely State of Mysore. In 1809, the British shifted their cantonment to Bangalore, outside the old city, and a grew up around it. Following Indias independence in 1947, Bangalore became the capital of Mysore State, the two urban settlements of Bangalore – city and cantonment – which had developed as independent entities merged into a single urban centre in 1949. The existing Kannada name, Bengalūru, was declared the name of the city in 2006. Bangalore is sometimes referred to as the Silicon Valley of India because of its role as the leading information technology exporter. Indian technological organisations ISRO, Infosys, Wipro and HAL are headquartered in the city, a demographically diverse city, Bangalore is the second fastest-growing major metropolis in India. Numerous state-owned aerospace and defence organisations, such as Bharat Electronics, Hindustan Aeronautics, the city also houses the Kannada film industry. The name Bangalore represents a version of the Kannada language name. It is the name of a village near kodegehalli and was copied by Kempegowda to the city of Bangalore, Bangalore was built on a venue earlier called as Shivanasamudram in the 16th century. The earliest reference to the name Bengalūru was found in a ninth-century Western Ganga Dynasty stone inscription on a vīra gallu, in this inscription found in Begur, Bengalūrū is referred to as a place in which a battle was fought in 890 CE. It states that the place was part of the Ganga Kingdom until 1004 and was known as Bengaval-uru, an apocryphal story recounts that the 12th century Hoysala king Veera Ballala II, while on a hunting expedition, lost his way in the forest. Tired and hungry, he came across an old woman who served him boiled beans. The grateful king named the place benda-kaal-uru, which evolved into Bengalūru. On 11 December 2005, the Government of Karnataka announced that it had accepted a proposal by Jnanpith Award winner U. R. Ananthamurthy to rename Bangalore to Bengalūru, on 27 September 2006, the Bruhat Bangalore Mahanagara Palike passed a resolution to implement the proposed name change

Weaving
–
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, felting, and braiding or plaiting, the longitudinal threads are called the warp and the lateral threads are the weft or filling. The method in which these threads are inter woven affects the characteristics of the cloth, cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. A fabric band which meets this definition of cloth can also be using other methods, including tablet weaving, back-strap. The way the warp and filling threads interlace with each other is called the weave, the majority of woven products are created with one of three basic weaves, plain weave, satin weave, or twill. Woven cloth can be plain, or can be woven in decorative or artistic design, in general, weaving involves using a loom to interlace two sets of threads at right angles to each other, the warp which runs longitudinally and the weft that crosses it. One warp thread is called an end and one weft thread is called a pick, the warp threads are held taut and in parallel to each other, typically in a loom. There are many types of looms, Weaving can be summarized as a repetition of these three actions, also called the primary motion of the loom. Beating-up or battening, where the weft is pushed up against the fell of the cloth by the reed. The warp is divided into two overlapping groups, or lines that run in two planes, one another, so the shuttle can be passed between them in a straight motion. Then, the group is lowered by the loom mechanism. Repeating these actions form a fabric mesh but without beating-up, the distance between the adjacent wefts would be irregular and far too large. The warp-beam is a wooden or metal cylinder on the back of the loom on which the warp is delivered, the threads of the warp extend in parallel order from the warp-beam to the front of the loom where they are attached to the cloth-roll. Each thread or group of threads of the passes through an opening in a heddle. The warp threads are separated by the heddles into two or more groups, each controlled and automatically drawn up and down by the motion of the heddles, where a complex design is required, the healds are raised by harness cords attached to a Jacquard machine. Every time the harness moves up or down, an opening is made between the threads of warp, through which the pick is inserted, traditionally the weft thread is inserted by a shuttle. On a conventional loom, the thread is carried on a pirn. A handloom weaver could propel the shuttle by throwing it from side to side with the aid of a picking stick, the picking΅ on a power loom is done by rapidly hitting the shuttle from each side using an overpick or underpick mechanism controlled by cams 80-250 times a minute

Sewing
–
Sewing is the craft of fastening or attaching objects using stitches made with a needle and thread. Sewing is one of the oldest of the arts, arising in the Paleolithic era. For thousands of years, all sewing was done by hand, fine hand sewing is a characteristic of high-quality tailoring, haute couture fashion, and custom dressmaking, and is pursued by both textile artists and hobbyists as a means of creative expression. The first known use of the sewing was in the 14th century. Sewing has an ancient history estimated to begin during the Paleolithic Age, Sewing was used to stitch together animal hides for clothing and for shelter. The weaving of cloth from natural fibres originated in the Middle East around 4000 BCE, and perhaps earlier during the Neolithic Age, during the Middle Ages, Europeans who could afford it employed seamstresses and tailors. Sewing for the most part was an occupation, and most sewing before the 19th century was practical. Clothing was an investment for most people, and women had an important role in extending the longevity of items of clothing. Clothing that was faded would be turned inside-out so that it could continue to be worn, once clothing became worn or torn, it would be taken apart and the reusable cloth sewn together into new items of clothing, made into quilts, or otherwise put to practical use. The many steps involved in making clothing from scratch meant that women often bartered their expertise in a skill with one another. Decorative needlework such as embroidery was a skill, and young women with the time. From the Middle Ages to the 17th century, sewing tools such as needles, decorative embroidery was valued in many cultures worldwide. Some examples are the Cretan Open Filling stitch, Romanian Couching or Oriental Couching, the stitches associated with embroidery spread by way of the trade routes that were active during the Middle Ages. European imperial settlements also spread embroidery and sewing techniques worldwide, however, there are instances of sewing techniques indigenous to cultures in distant locations from one another, where cross-cultural communication would have been historically unlikely. For example, a method of reverse appliqué known to areas of South America is also known to Southeast Asia, the Industrial Revolution shifted the production of textiles from the household to the mills. In the early decades of the Industrial Revolution, the machinery produced whole cloth, the worlds first sewing machine was patented in 1790 by Thomas Saint. By the early 1840s, other early sewing machines began to appear, by the 1850s, Isaac Singer developed the first sewing machines that could operate quickly and accurately and surpass the productivity of a seamstress or tailor sewing by hand. While much clothing was produced at home by female members of the family

Basket
–
A basket is a container which is traditionally constructed from stiff fibers, which can be made from a range of materials, including wood splints, runners, and cane. While most baskets are made from plant materials, other such as horsehair, baleen. Baskets are generally woven by hand, some baskets are fitted with a lid, others are left open. Baskets serve utilitarian as well as aesthetic purposes, some baskets are ceremonial, that is religious, in nature. Prior to the invention of woven baskets, people used tree bark to make simple containers and these containers could be used to transport gathered food and other items, but crumble after only a few uses. Weaving strips of bark or other plant material to support the bark containers would be the next step, the last innovation appears to be baskets so tightly woven that they could hold water. Depending on soil conditions, baskets may or may not be preserved in the archaeological record, sites in the Middle East show that weaving techniques were used to make mats and possibly also baskets, circa 8000 BCE. Twined baskets date back to 7000 BCE in Oasisamerica, baskets made with interwoven techniques were common at 3000 BCE. Baskets were originally designed as multi-purpose baskets to carry and store, the plant life available in a region affects the choice of material, which in turn influences the weaving technique. The practice of basket making has evolved into an art, artistic freedom allows basket makers a wide choice of colors, materials, sizes, patterns, and details. The carrying of a basket on the head, particularly by women, has long been practised. Representations of this in Ancient Greek art are called Canephorae, the phrase to hell in a handbasket means to rapidly deteriorate. The origin of use is unclear. Basket is sometimes used as an adjective towards a person who is out of wedlock. This occurs more commonly in British English, basket also refers to a bulge in a mans crotch. Materials have been used by basket makers, Wicker Straw Plastic Metal Bamboo Palm Zepeda, ocean Power, Poems from the Desert. Baskets, The Womens Committee of the Philadelphia Museum of Art

Pine
–
A pine is any conifer in the genus Pinus, /ˈpiːnuːs/, of the family Pinaceae. Pinus is the genus in the subfamily Pinoideae. The Plant List compiled by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 126 species names of pines as current, together with 35 unresolved species, the modern English name pine derives from Latin pinus, which some have traced to the Indo-European base *pīt- ‘resin’. Before the 19th century, pines were often referred to as firs, the genus is divided into three subgenera, which can be distinguished by cone, seed, and leaf characters, Pinus subg. Pinus, the yellow, or hard pine group, generally harder wood. Ducampopinus, the foxtail or pinyon group Pinus subg, strobus, the white, or soft pine group, generally with softer wood and five needles per fascicle Most regions of the Northern Hemisphere host some native species of pines. One species crosses the equator in Sumatra to 2°S, in North America, various species occur in regions at latitudes from as far north as 66°N to as far south as 12°N. Various species have been introduced to temperate and subtropical regions of both hemispheres, where they are grown as timber or cultivated as ornamental plants in parks, a number of such introduced species have become invasive and threaten native ecosystems. Pine trees are evergreen, coniferous trees growing 3–80 m tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is a 81.79 m tall ponderosa pine located in southern Oregons Rogue River-Siskiyou National Forest, the bark of most pines is thick and scaly, but some species have thin, flaky bark. The branches are produced in regular pseudo whorls, actually a very tight spiral, the spiral growth of branches, needles, and cone scales are arranged in Fibonacci number ratios. The new spring shoots are sometimes called candles, they are covered in brown or whitish bud scales and point upward at first, then turn green. These candles offer foresters a means to evaluate fertility of the soil, pines are long-lived, and typically reach ages of 100–1,000 years, some even more. The longest-lived is the Great Basin bristlecone pine, Pinus longaeva, one individual of this species, dubbed Methuselah, is one of the worlds oldest living organisms at around 4,600 years old. This tree can be found in the White Mountains of California, an older tree, now cut down, was dated at 4,900 years old. It was discovered in a grove beneath Wheeler Peak and it is now known as Prometheus after the Greek immortal, pines have four types of leaf, Seed leaves on seedlings, born in a whorl of 4–24. Juvenile leaves, which follow immediately on seedlings and young plants, 2–6 cm long, single, green or often blue-green and these are produced for six months to five years, rarely longer. Scale leaves, similar to bud scales, small, brown and non-photosynthetic, needles, the adult leaves, are green and bundled in clusters called fascicles

Hide (skin)
–
A hide or skin is an animal skin treated for human use. The word hide is related to the Dutch word huid which refers to mammal skin, common commercial hides include leather from cattle and other livestock animals, buckskin, alligator skin and snake skin. All are used for shoes, clothes and other fashion accessories, leather is also used in upholstery, interior decorating, horse tack and harnesses. Such skins are sometimes still gathered from hunting and processed at a domestic or artisanal level but most leather making is now industrialized, various tannins are used for this purpose. The term hide is sometimes expanded to include furs, which are harvested from various species, including cats, mustelids, archaeologists believe that animal hides provided an important source of clothing and shelter for all prehistoric humans and their use continued among non-agricultural societies into modern times. The Inuit, for example, used animal hides for summer tents, waterproof clothes, in early medieval era hides were used to protect wooden castles and defence buildings from setting alight during a siege. Various American Indian tribes used hides in the construction of tepees and wigwams, moccasins and they were sometimes used as window coverings. Until the invention of plastic heads in the 1950s, animal hides or metal was used. Parchment and vellum—a kind of made from processed skins—was introduced to the Eastern Mediterranean during the Iron Age. The Assize of Weights and Measures—one of the statutes of uncertain date from c. 1300—mentions rawhide, gloves, parchment, a standardized shipload of leather consisted of 20 dicker of 10 cowhides. Rabbit and squirrel skins were traded and taxed in timbers of 40 hides each, skins were also traded in binds of 32 or 33 skins each, while gloves were sold in dickers of 10 pair and dozens of 12 pair. The parchment and vellum was traded based on dozens of the original sheepskins from which they were prepared, rare furs have been a notable status symbol throughout history. Ermine fur was particularly associated with European nobility, with the black-tipped tails arranged around the edges of the robes to produce a pattern of black diamonds on a white field, natural leather continues to be used for many expensive products from limousine upholstery to designer cellular phone cases. There are, however, many forms of artificial leather and fur now available, animal hides are stretched, dried, and tanned. Most hides are processed from domesticated animals, the most common animals used for fur—mink and rabbit—are similarly raised in captivity. Some others—including lynx and wolves—are still trapped in the wild for their fur, presently, hides are mainly used as clothing, particularly as coats and footwear. It is also used for bookbinding, many traditional drums, especially hand drums like the pandeiro, continue to be made using natural hides. The alligator drum was formerly important in Chinese music, the African-American banjo was originally made from skins but is now often synthetic

Grass
–
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns, Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath, with ca 780 genera and around 12,000 species, Poaceae are the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. Grasslands such as savannah and prairie grasses are dominant are estimated to constitute 40. 5% of the land area of the Earth, excluding Greenland. Grasses are also an important part of the vegetation in many habitats, including wetlands, forests. Though commonly called grasses, seagrasses, rushes, and sedges fall outside this family, the rushes and sedges are related to the Poaceae, being members of the order Poales, but the seagrasses are members of order Alismatales. The name Poaceae was given by John Hendley Barnhart in 1895, based on the tribe Poeae described in 1814 by Robert Brown, the term is derived from the Ancient Greek πόα. Grasses include some of the most versatile plant life-forms, a cladogram shows subfamilies and approximate species numbers in brackets, Before 2005, fossil findings indicated that grasses evolved around 55 million years ago. Recent findings of grass-like phytoliths in Cretaceous dinosaur coprolites have pushed this back to 66 million years ago. In 2011, revised dating of the origins of the rice tribe Oryzeae suggested a date as early as 107 to 129 Mya, a multituberculate mammal with grass-eating adaptations seems to suggest that grasses were already around at 120 mya. This separation occurred within the short time span of about 4 million years. Grass leaves are always alternate and distichous, and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem, the leaf blades of many grasses are hardened with silica phytoliths, which discourage grazing animals, some, such as sword grass, are sharp enough to cut human skin. A membranous appendage or fringe of hairs called the ligule lies at the junction between sheath and blade, preventing water or insects from penetrating into the sheath, flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. The spikelets are further grouped into panicles or spikes, the part of the spikelet that bears the florets is called the rachilla. A spikelet consists of two bracts at the base, called glumes, followed by one or more florets, a floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The flowers are usually hermaphroditic—maize being an important exception—and anemophilous or wind-pollinated, the perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea, these are generally interpreted to be modified sepals. This complex structure can be seen in the image on the right, the fruit of grasses is a caryopsis, in which the seed coat is fused to the fruit wall

Indigenous people
–
Groups are usually described as indigenous when they maintain traditions or other aspects of an early culture that is associated with a given region. Not all indigenous peoples share such characteristics, Indigenous societies are found in every inhabited climate zone and continent of the world. Estimates put the population of indigenous peoples from 220 million to 350 million. The adjective indigenous is derived from the Latin word indigena, which is based on the root gen- to be born with a form of the prefix in in. Any given people, ethnic group or community may be described as indigenous in reference to some particular region or location that they see as their tribal land claim. Other terms used to refer to indigenous populations are aboriginal, native, original, james Anaya, former Special Rapporteur on the Rights of Indigenous Peoples, has defined indigenous peoples as living descendants of pre-invasion inhabitants of lands now dominated by others. They are culturally distinct groups that find themselves engulfed by other settler societies born of forces of empire, throughout history, different states designate the groups within their boundaries that are recognized as indigenous peoples according to international or national legislation by different terms. Their ability to influence and participate in the policies that may exercise jurisdiction over their traditional lands. The presence of external laws, claims and cultural mores either potentially or actually act to constrain the practices and observances of an indigenous society. These constraints can be observed even when the society is regulated largely by its own tradition. They may be imposed, or arise as unintended consequence of trans-cultural interaction. They may have an effect, even where countered by other external influences. This definition has some limitations, because the definition applies mainly to pre-colonial populations, the primary impetus in considering indigenous identity comes from the post-colonial movements and considering the historical impacts on populations by the European imperialism. Greek sources of the Classical period acknowledge the existence of indigenous people. These peoples inhabited lands surrounding the Aegean Sea before the subsequent migrations of the Hellenic ancestors claimed by these authors, the disposition and precise identity of this former group is elusive, and sources such as Homer, Hesiod and Herodotus give varying, partially mythological accounts. However, it is clear that cultures existed whose indigenous characteristics were distinguished by the subsequent Hellenic cultures, greco-Roman society flourished between 250 BC and 480 AD and commanded successive waves of conquests that gripped more than half of the globe. The rapid and extensive spread of the various European powers from the early 15th century onwards had an impact upon many of the indigenous cultures with whom they came into contact. The Canary Islands had an indigenous population called the Guanches whose origin is still the subject of discussion among historians, the United Nations estimates that there are over 370 million indigenous people living in over 70 countries worldwide

Religion
–
Religions have sacred histories and narratives, which may be preserved in sacred scriptures, and symbols and holy places, that aim mostly to give a meaning to life. Religions may contain symbolic stories, which are said by followers to be true, that have the side purpose of explaining the origin of life. Traditionally, faith, in addition to reason, has considered a source of religious beliefs. There are an estimated 10,000 distinct religions worldwide, about 84% of the worlds population is affiliated with one of the five largest religions, namely Christianity, Islam, Hinduism, Buddhism or forms of folk religion. With the onset of the modernisation of and the revolution in the western world. The religiously unaffiliated demographic include those who do not identify with any religion, atheists. While the religiously unaffiliated have grown globally, many of the religiously unaffiliated still have various religious beliefs, about 16% of the worlds population is religiously unaffiliated. The study of religion encompasses a variety of academic disciplines, including theology, comparative religion. Theories of religion offer various explanations for the origins and workings of religion, Religion is derived from the Latin religiō, the ultimate origins of which are obscure. One possible interpretation traced to Cicero, connects lego read, i. e. re with lego in the sense of choose, go over again or consider carefully. The medieval usage alternates with order in designating bonded communities like those of monastic orders, we hear of the religion of the Golden Fleece, of a knight of the religion of Avys. In the ancient and medieval world, the etymological Latin root religio was understood as a virtue of worship, never as doctrine, practice. In the Quran, the Arabic word din is often translated as religion in modern translations and it was in the 19th century that the terms Buddhism, Hinduism, Taoism, and Confucianism first emerged. Max Müller characterized many other cultures around the world, including Egypt, Persia, what is called ancient religion today, they would have only called law. Some languages have words that can be translated as religion, but they may use them in a different way. For example, the Sanskrit word dharma, sometimes translated as religion, throughout classical South Asia, the study of law consisted of concepts such as penance through piety and ceremonial as well as practical traditions. Medieval Japan at first had a union between imperial law and universal or Buddha law, but these later became independent sources of power. There is no equivalent of religion in Hebrew, and Judaism does not distinguish clearly between religious, national, racial, or ethnic identities

Juncaceae
–
Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of eight genera and about 464 known species of slow-growing and they often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is Juncus, most of the Juncus species grow exclusively in wetland habitats. A few rushes, such as Juncus bufonius are annuals, the leaves are evergreen and well-developed in a basal aggregation on an erect stem. Only in the genus Distichia are the leaves distichous, the rushes of the genus Juncus have flat, hairless leaves or cylindrical leaves. The leaves of the wood-rushes of the genus Luzula are always flat, the plants are hermaphroditic or, rarely, dioecious. The small flowers are arranged in inflorescences of loose cymes, and this family typically has reduced perianth segments called tepals. These are usually arranged in two whorls, each containing three thin, papery tepals and they are not bright or flashy in appearance, and their color can vary from greenish to whitish, brown, purple, black, or hyaline. The three stigmas are in the center of the flowers, as is characteristic of monocots, all of the flower parts appear in multiples of three. The fruit is usually a nonfleshy, three-sectioned dehiscent capsule containing many seeds, the dried pith of plants of this family were used to make a type of candle known as a rushlight. The soft rush is called igusa in Japanese and is used to weave the soft surface cover of tatami mats, in medieval Europe, loose fresh rushes would be strewn on earthen floors in dwellings for cleanliness and insulation. Particularly favored for such a purpose was Acorus calamus, but despite its vernacular name sweet rush, it is a plant from a different monocot order.

Palm tree
–
The Arecaceae are a botanical family of perennial climbers, shrubs, acaules and trees commonly known as palm trees. They are flowering plants, a family in the monocot order Arecales, currently 181 genera with around 2600 species are known, most of them restricted to tropical, subtropical, and warm temperate climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, however, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families and they have been important to humans throughout much of history. Many common products and foods are derived from palms, and palms are widely used in landscaping, making them one of the most economically important plants. In many historical cultures, palms were symbols for such ideas as victory, peace, for inhabitants of cooler climates today, palms symbolize the tropics and vacations. Whether as shrubs, trees, or vines, palms have two methods of growth, solitary or clustered, the common representation is that of a solitary shoot ending in a crown of leaves. This monopodial character may be exhibited by prostrate, trunkless, some common palms restricted to solitary growth include Washingtonia and Roystonea. Palms may instead grow in sparse though dense clusters, the trunk develops an axillary bud at a leaf node, usually near the base, from which a new shoot emerges. The new shoot, in turn, produces an axillary bud, exclusively sympodial genera include many of the rattans, Guihaia, and Rhapis. Several palm genera have both solitary and clustering members, Palms which are usually solitary may grow in clusters, and vice versa. These aberrations suggest the habit operates on a single gene, Palms have large, evergreen leaves that are either palmately or pinnately compound and spirally arranged at the top of the stem. The leaves have a sheath at the base that usually splits open on one side at maturity. The inflorescence is a spadix or spike surrounded by one or more bracts or spathes that become woody at maturity, the flowers are generally small and white, radially symmetric, and can be either uni- or bisexual. The sepals and petals usually number three each, and may be distinct or joined at the base, the stamens generally number six, with filaments that may be separate, attached to each other, or attached to the pistil at the base. The fruit is usually a single-seeded drupe but some genera may contain two or more seeds in each fruit, like all monocots, palms do not have the ability to increase the width of a stem via the same kind of vascular cambium found in non-monocot woody plants. This explains the shape of the trunk that is often seen in palms. The Arecaceae are notable among monocots for their height and for the size of their seeds, leaves, Ceroxylon quindiuense, Colombias national tree, is the tallest monocot in the world, reaching up to 60 m tall

Yucca
–
Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40-50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and they are native to the hot and dry parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava, consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, yuca. It is commonly found growing in rural graveyards and when in bloom the cluster of flowers on a thin stalk appear as floating apparitions, the natural distribution range of the genus Yucca covers a vast area of the Americas. The genus is represented throughout Mexico and extends into Guatemala and it also extends to the north through Baja California in the west, northwards into the southwestern United States, through the drier central states as far north as southern Alberta in Canada. Yucca is also native to the lowlands and dry scrub of the Gulf. Yuccas have adapted to an equally vast range of climatic and ecological conditions, Yucca species are the host plants for the caterpillars of the yucca giant-skipper, ursine giant-skipper, and Streckers giant-skipper. Species of yucca have adapted to a variety of climates in mountains, coastal sand, grasslands and prairies as well as rocky badlands. Most species of yucca have thick, waxy skins to prevent loss of water through evaporation and they frequently store water in thick roots. Some yuccas store water in thick, fleshy leaves, some desert plants have an oily coating on their leaves or pads that traps moisture, thereby reducing water loss. Some species drop their leaves during drought to prevent the loss of water through transpiration, dead leaves of yucca collecting against the trunk of the trees help protect it from the sun. The channeled leaves of a yucca direct dew and rainfall water to their roots, yuccas are said to be fire adapted, that is, they grow and spread vigorously after wildfires. Yuccas are widely grown as ornamental plants in gardens, many species also bear edible parts, including fruits, seeds, flowers, flowering stems, and more rarely roots. References to yucca root as food often arise from confusion with the similarly pronounced, roots of soaptree yucca are high in saponins and are used as a shampoo in Native American rituals. Dried yucca leaves and trunk fibers have a low ignition temperature, in rural Appalachian areas, species such as Yucca filamentosa are referred to as meat hangers. The tough, fibrous leaves with their tips were used to puncture meat. Yuccas are widely grown as architectural plants providing a dramatic accent to landscape design and they tolerate a range of conditions, but are best grown in full sun in subtropical or mild temperate areas. In gardening centres and horticultural catalogues they are grouped with other architectural plants such as cordylines

New Zealand flax
–
New Zealand flax describes the common New Zealand perennial plants Phormium tenax and Phormium colensoi, known by the Māori names harakeke and wharariki respectively. They have played an important part in the cultural and economic history of New Zealand for both the Māori people and the later European settlers. Both species and their cultivars have now been widely distributed to temperate regions of the world as ornamental garden plants - and to lesser extent for fibre production. Although the Māori made textiles from a number of plants, including tī kōuka, tōī, pingao, kiekie, toetoe and the paper mulberry. As Captain Cook wrote, “Of the leaves of plants, with very little preparation, they make all their common apparel. They also made baskets, mats, and fishing nets from the undressed flax, the Māori practised advanced weft twining in phormium fibre cloaks. Leaves were cut near the base of the plant using a mussel shell or specially shaped rocks. The flax fibre, called muka, is washed, pounded. The cords form the base cloth for intricate cloaks or garments such as the highly prized traditional feather cloak. Different type of cloaks, such as kahu kiwi and kahu kākā, were produced by adorning them with colourful feathers from different native birds, such as kiwi, kākā, tui, huia and kererū. The handmade flax cording and ropes had such great strength that they were used to successfully bind together sections of hollowed out logs to create huge ocean-going canoes. With the help of wakas, pre-European Māori deployed seine nets which could be one thousand metres long. The nets were woven from green flax, with weights and light wood or gourd floats. It was also used to make rigging, sails and lengthy anchor warps, frayed ends of flax leaves were fashioned into torches and lights for use at night. The dried flower stalks, which are light, were bound together with flax twine to make river rafts called mokihi. For centuries, Māori have used nectar from the flowers for medicinal purposes, boiled and crushed harakeke roots were applied externally as a poultice for boils, tumours and abscesses, as well as to varicose ulcers. Juice from pounded roots was used as a disinfectant, and taken internally to relieve constipation or expel worms, the pulp of pounded leaves was applied as dressings to bullet, bayonet or other wounds. The gum-like sap produced by harakeke contains enzymes that give it blood clotting, splints were fashioned from korari and leaves, and fine cords of muka fibre utilise the styptic properties of the gel before being used to stitch wounds

Root
–
In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil. Roots can also be aerial or aerating, that is growing up above the ground or especially above water, furthermore, a stem normally occurring below ground is not exceptional either. Therefore, the root is best defined as the non-leaf, non-nodes bearing parts of the plants body, however, important internal structural differences between stems and roots exist. The fossil record of roots – or rather, infilled voids where roots rotted after death – spans back to the late Silurian and their identification is difficult, because casts and molds of roots are so similar in appearance to animal burrows. They can be discriminated using a range of features, the first root that comes from a plant is called the radicle. In response to the concentration of nutrients, roots also synthesise cytokinin, Roots often function in storage of food and nutrients. The roots of most vascular plant species enter into symbiosis with fungi to form mycorrhizae. In its simplest form, the root architecture refers to the spatial configuration of a plant’s root system. This system can be complex and is dependent upon multiple factors such as the species of the plant itself, the composition of the soil. The configuration of root systems serves to support the plant, compete with other plants. Roots grow to specific conditions, which, if changed, can impede a plants growth. For example, a system that has developed in dry soil may not be as efficient in flooded soil, yet plants are able to adapt to other changes in the environment. Root architecture plays the important role of providing a supply of nutrients and water as well as anchorage. The main terms used to classify the architecture of a system are, Branch magnitude. Root angle, the angle of a lateral root’s base around the parent root’s circumference, the angle of a lateral root from its parent root. Link radius, the diameter of a root, all components of the root architecture are regulated through a complex interaction between genetic responses and responses due to environmental stimuli. These developmental stimuli are categorised as intrinsic, the genetic and nutritional influences, or extrinsic, the main hormones and respective pathways responsible for root architecture development include, Auxin – Auxin promotes root initiation, root emergence and primary root elongation. Cytokinins – Cytokinins regulate root apical meristem size and promote lateral root elongation, gibberellins – Together with ethylene they promote crown primordia growth and elongation

Bark
–
BARK was an early electromechanical computer. BARK was built using standard phone relays, implementing a 32-bit binary machine and it could perform addition in 150 ms and multiplication in 250 ms. It had a memory with 50 registers and 100 constants and it was later expanded to double the memory. Howard Aiken stated in reference to BARK This is the first computer I have seen outside Harvard that actually works, BARK was developed by Matematikmaskinnämnden a few years before BESK. The machine was built with 8000 standard phone relays,80 km of cable and it was completed in February 1950 at a cost of 400000 Swedish kronor, became operational on April 281950, and was taken offline on September 22,1954. The engineers on the led by Conny Palm were Harry Freese, Gösta Neovius, Olle Karlqvist, Carl-Erik Fröberg, G. Kellberg, Björn Lind, Arne Lindberger, P. Petersson.

Phragmites
–
Phragmites is a genus of four species of large perennial grasses found in wetlands throughout temperate and tropical regions of the world. The World Checklist of Selected Plant Families, maintained by Kew Garden in London, – Japan, Korea, Ryukyu Islands, Russian Far East Phragmites karka Trin. About 130 other synonyms have been proposed, and some have been widely used, arundo phragmites L. and Phragmites vulgaris Crép. Recent studies have characterised morphological distinctions between the introduced and native stands of Phragmites australis in North America, americanus – the North American genotype has been described as a distinct subspecies, subsp. Americanus, and Phragmites australis – the Eurasian genotype is sometimes referred to as subsp, altissimus Clayton is an accepted subspecies of P. australis. Phragmites australis var. marsillyanus Kerguélen is a variety of Phragmites australis. In North America, the status of Phragmites australis was a source of confusion and it was commonly considered an exotic species and often invasive species, introduced from Europe. However, there is evidence of the existence of Phragmites as a plant in North America long before European colonization of the continent. It is now known that the North American native forms of P. a. subsp, americanus are markedly less vigorous than European forms. The recent marked expansion of Phragmites in North America may be due to the more vigorous, Phragmites outcompetes native vegetation and lowers the local plant biodiversity. Phragmites forms dense thickets of vegetation that is unsuitable habitat for native fauna, Phragmites displaces native plants species such as wild rice, cattails, and native wetland orchids. Phragmites has a high ground biomass that blocks light to other plants allowing areas to turn into Phragmites monoculture very quickly. Decomposing Phragmites increases the rate of marsh accretion more rapidly than would occur with native marsh vegetation, australis is causing serious problems for many other North American hydrophyte wetland plants, including the native Phragmites australis subsp. Gallic acid released by Phragmites is degraded by ultraviolet light to produce acid, effectively hitting susceptible plants. Phragmites are so difficult to control one of the most effective methods of eradicating the plant is to burn it over 2-3 seasons. The roots grow so deep and strong that one burn is not enough, ongoing research suggests that goats could be effectively used to control the species. Phragmites australis, common reed, commonly forms extensive stands, which may be as much as 1 square kilometre or more in extent, where conditions are suitable it can also spread at 5 metres or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to 1 metre or so deep, the erect stems grow to 2–6 metres tall, with the tallest plants growing in areas with hot summers and fertile growing conditions

Willow
–
Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow. Some willows are low-growing or creeping shrubs, for example, the dwarf willow rarely exceeds 6 cm in height, though it spreads widely across the ground. Willows all have abundant watery bark sap, which is charged with salicylic acid, soft, usually pliant, tough wood, slender branches. The roots are remarkable for their toughness, size, and tenacity to life, the leaves are typically elongated, but may also be round to oval, frequently with serrated edges. Most species are deciduous, semievergreen willows with coriaceous leaves are rare, e. g. Salix micans, all the buds are lateral, no absolutely terminal bud is ever formed. The buds are covered by a single scale, usually, the bud scale is fused into a cap-like shape, but in some species it wraps around and the edges overlap. The leaves are simple, feather-veined, and typically linear-lanceolate, usually they are serrate, rounded at base, acute or acuminate. The leaf petioles are short, the often very conspicuous, resembling tiny, round leaves. On some species, however, they are small, inconspicuous, in color, the leaves show a great variety of greens, ranging from yellowish to bluish. Willows are dioecious, with male and female flowers appearing as catkins on separate plants and this scale is square, entire, and very hairy. The anthers are rose-colored in the bud, but orange or purple after the flower opens, they are two-celled, the filaments are threadlike, usually pale brown, and often bald. The ovary is one-celled, the style two-lobed, and the ovules numerous, almost all willows take root very readily from cuttings or where broken branches lie on the ground. The few exceptions include the willow and peachleaf willow. One famous example of such growth from cuttings involves the poet Alexander Pope and this twig was planted and thrived, and legend has it that all of Englands weeping willows are descended from this first one. Willows are often planted on the borders of streams so their interlacing roots may protect the bank against the action of the water, frequently, the roots are much larger than the stem which grows from them. Willows are very cross-compatible, and numerous hybrids occur, both naturally and in cultivation, a well-known ornamental example is the weeping willow, which is a hybrid of Peking willow from China and white willow from Europe. The hybrid cultivar Boydii has gained the Royal Horticultural Societys Award of Garden Merit, Willows are used as food plants by the larvae of some Lepidoptera species, such as the mourning cloak butterfly. Ants, such as ants, are common on willows inhabited by aphids, coming to collect aphid honeydew

Oak
–
An oak is a tree or shrub in the genus Quercus of the beech family, Fagaceae. There are approximately 600 extant species of oaks, the common name oak also appears in the names of species in related genera, notably Lithocarpus, as well as in those of unrelated species such as Grevillea robusta and the Casuarinaceae. North America contains the largest number of oak species, with approximately 90 occurring in the United States, the second greatest center of oak diversity is China, which contains approximately 100 species. Oaks have spirally arranged leaves, with lobate margins in many species, also, the acorns contain tannic acid, as do the leaves, which helps to guard from fungi and insects. Many deciduous species are marcescent, not dropping dead leaves until spring, in spring, a single oak tree produces both male flowers and small female flowers. The fruit is a nut called an acorn, borne in a structure known as a cupule, each acorn contains one seed and takes 6–18 months to mature. The live oaks are distinguished for being evergreen, but are not actually a distinct group, the oak tree is a flowering plant. Oaks may be divided into two genera and a number of sections, The genus Quercus is divided into the following sections, Quercus, the white oaks of Europe, Asia and North America. Styles are short, acorns mature in 6 months and taste sweet or slightly bitter, the leaves mostly lack a bristle on their lobe tips, which are usually rounded. The type species is Quercus robur, Mesobalanus, Hungarian oak and its relatives of Europe and Asia. Styles long, acorns mature in about 6 months and taste bitter, the section Mesobalanus is closely related to section Quercus and sometimes included in it. Cerris, the Turkey oak and its relatives of Europe and Asia, styles long, acorn mature in 18 months and taste very bitter. The inside of the shell is hairless. Its leaves typically have sharp tips, with bristles at the lobe tip. Protobalanus, the live oak and its relatives, in southwest United States. Styles short, acorns mature in 18 months and taste very bitter, the inside of the acorn shell appears woolly. Leaves typically have sharp tips, with bristles at the lobe tip. Lobatae, the red oaks of North America, Central America, styles long, acorns mature in 18 months and taste very bitter

Fraxinus /ˈfræksᵻnəs/, English name ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of medium to large trees, mostly deciduous though a few subtropical species are evergreen. The genus is widespread across much of Europe, Asia and North America, the trees common English name, ash, traces back to the Old English æsc, while the generic name originated in Latin. Both words also mean spear in their respective languages, the leaves are opposite, and mostly pinnately compound, simple in a few species. The seeds, popularly known as keys or helicopter seeds, are a type of known as a samara. Rowans or mountain ashes have leaves and buds superficially similar to those of true ashes, species are organized according to phylogenetic analysis. – California ash or two-petal ash Fraxinus anomala Torr, ex S.

The emerald ash borer is a wood-boring beetle accidentally introduced to North America from eastern Asia via solid wood packing material in the late 1980s to early 1990s and it has killed tens of millions of trees in 15 states in the United States and adjacent Ontario in Canada. It threatens some seven billion ash trees in North America, the public is being cautioned not to transport unfinished wood products, such as firewood, to slow the spread of this insect pest. The disease has infected about 90% of Denmarks ash trees, in 2016, the ash tree was reported as in danger of extinction in Europe

Pohnpei
–
Pohnpei upon a stone altar is an island of the Senyavin Islands which are part of the larger Caroline Islands group. It belongs to Pohnpei State, one of the four states in the Federated States of Micronesia, major population centers on Pohnpei include Palikir, the FSMs capital, and Kolonia, the capital of Pohnpei State. Pohnpei Island is the largest, highest, most populous, the islanders of Pohnpei have a reputation as being the most welcoming of outsiders among residents of the island group. Pohnpei also contains a wealth of biodiversity and it is also one of the wettest places on Earth with annual recorded rainfall exceeding 7,600 millimetres each year in certain mountainous locations. It is home to the ka tree found only in Pohnpei, the highest point of the island is Mount Nanlaud at 772 or 782 metres. Pohnpei is home to several bird species including four endemic species, the Pohnpei lorikeet, the Pohnpei fantail, the Pohnpei flycatcher. A fifth endemic, the Pohnpei starling, is thought to have gone extinct. The only land reptiles are a few species of lizard, originally, only three mammals existed, rats, bats and dogs. Pigs were introduced, some are now feral, as are the deer brought during German times, the lagoons are rich in fish, mollusks, turtles and other marine fauna. Pohnpei belongs to the Tropical rainforest climate zone and it is also one of the wettest places on earth with annual recorded rainfall exceeding 7,600 millimetres each year in certain mountainous locations. Pohnpeian legend recounts that the Saudeleur rulers, the first to bring government to Pohnpei, were of foreign origin, the Saudeleur centralized form of absolute rule is characterized in Pohnpeian legend as becoming increasingly oppressive over several generations. Arbitrary and onerous demands, as well as a reputation for offending Pohnpeian deities, the Saudeleur Dynasty ended with the invasion of Isokelekel, another semi-mythical foreigner, who replaced the Saudeleur rule with the more decentralized nahnmwarki system in existence today. Pohnpeian historic society was structured into five tribes, various clans and sub-clans. The tribes were organized on a feudal basis, in theory, all land belonged to the chiefs, who received regular tribute and whose rule was absolute. Punishments administered by chiefs included death and banishment, tribal wars included looting, destruction of houses and canoes and killing of prisoners. Pre-Spanish population estimates are deemed unreliable, pohnpeis first European visitor was Álvaro de Saavedra on 14 September 1529 shortly before his death, when trying to find the way back to New Spain. He charted it as San Bartolomé and called this one and the islands as Los Pintados because the natives were frequently tattooed. It was later visited by the Portuguese navigator Pedro Fernandes de Queirós, on 23 December 1595, his description is brief, he made no attempt to land

Rattan
–
Rattan is the name for roughly 600 species of old world climbing palms belonging to subfamily Calamoideae. Rattan is also known as manila, or malacca, named after the ports of shipment Manila and Malacca City, the climbing habit is associated with the characteristics of its flexible woody stem, derived typically from a secondary growth, makes rattan a liana rather than a true wood. Calamoideae also includes tree palms such as Raphia and Metroxylon and shrub palms such as Salacca and they dont have spinose stems and climb by means of their reflexed terminal leaflets. Of these only Desmoncus spp. furnish stems of sufficiently good quality to be used as rattan cane substitutes, there are 13 different genera of rattans that include around 600 species. The largest rattan genus is Calamus, distributed in Asia except for one species represented in Africa, the rattan genera and their distribution, In Uhl & Dransfield, and also Dransfield & Manokaran, a great deal of basic introductory information is available. Available rattan floras and monographs by region, Uses by taxon, rattans are also superficially similar to bamboo. Unlike bamboo, rattan stems are solid, and most species need structural support, many rattans have spines which act as hooks to aid climbing over other plants, and to deter herbivores. Rattans have been known to grow up to hundreds of metres long, most of the worlds rattan population exist in Indonesia, distributed among the islands Borneo, Sulawesi, and Sumbawa. The rest of the supply comes from the Philippines, Sri Lanka, Malaysia. In forests where rattan grows, its value can help protect forest land, by providing an alternative to loggers who forgo timber logging. Rattan is much easier to harvest, requires simpler tools and is easier to transport. It also grows faster than most tropical wood. This makes it a tool in forest maintenance, since it provides a profitable crop that depends on rather than replaces trees. It remains to be seen whether rattan can be as profitable or useful as the alternatives, rattans are threatened with overexploitation, as harvesters are cutting stems too young and reducing their ability to resprout. Unsustainable harvesting of rattan can lead to forest degradation, affecting overall forest ecosystem services, the use of toxic chemicals and petrol in the processing of rattan affects soil, air and water resources, and also ultimately peoples health. Meanwhile, the method of rattan production is threatening the plants long-term supply. Generally, raw rattan is processed into products to be used as materials in furniture making. The various species of rattan range from millimetres up to 5–7 cm in diameter

Hickory is a type of tree, comprising the genus Carya. The genus includes 17–19 species of trees with pinnately compound leaves. Five or six species are native to China, Indochina, and India, as many as 12 are native to the United States, four are found in Mexico, Hickory flowers are small, yellow-green catkins produced in spring. The fruit is a globose or oval nut, 2–5 cm long and 1. 5–3 cm diameter, enclosed in a four-valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan, beaked hickory is a species formerly classified as Carya sinensis, but now adjudged in the monotypic genus Annamocarya. In the APG system, genus Carya has been moved to the Fagales order. Sinocarya – Asian hickories Carya dabieshanensis M. C, liu – Dabie Shan hickory Carya cathayensis Sarg.

Phylloxeridae are related to aphids and have a complex life cycle. Eggs hatch in spring and the galls quickly form around the developing insects. Phylloxera galls may damage weakened or stressed hickories, but are generally harmless, the pecan gall curculio is a true weevil species also found feeding on galls of the hickory leaf stem gall phylloxera. The banded hickory borer is also found on hickories, some fruits are borderline and difficult to categorize. Hickory nuts and walnuts in the Juglandaceae family grow within an outer husk, tryma is a specialized term for such nut-like drupes. Hickory wood is hard, stiff, dense and shock resistant. Paddles are often made from hickory, Hickory is replacing ash as the wood of choice for Scottish shinty sticks

Oval
–
An oval is a closed curve in a plane which loosely resembles the outline of an egg. The term is not very specific, but in areas it is given a more precise definition. In common English, the term is used in a broader sense, the three-dimensional version of an oval is called an ovoid. The term oval when used to describe curves in geometry is not well-defined, many distinct curves are commonly called ovals or are said to have an oval shape. Generally, to be called an oval, a plane curve should resemble the outline of an egg or an ellipse, the adjectives ovoidal and ovate mean having the characteristic of being an ovoid, and are often used as synonyms for egg-shaped. In the theory of planes, an oval is a set of n +1 points in a projective plane of order n. An ovoid in the projective geometry PG is a set of q2 +1 points such that no three points are collinear. At each point of an all the tangent lines to the ovoid lie in a single plane. The shape of an egg is approximated by long half of a spheroid, joined to a short half of a roughly spherical ellipsoid. These are joined at the equator and sharing a principal axis of rotational symmetry, although the term egg-shaped usually implies a lack of reflection symmetry across the equatorial plane, it may also refer to true prolate ellipsoids. It can also be used to describe the 2-dimensional figure that, if revolved around its major axis, in technical drawing, an oval is a figure constructed from two pairs of arcs, with two different radii. The arcs are joined at a point in which lines tangential to both joining arcs lie on the line, thus making the joint smooth. Any point of an oval belongs to an arc with a constant radius, but in an ellipse, in common speech, oval means a shape rather like an egg or an ellipse, which may be two-dimensional or three-dimensional. It also often refers to a figure that resembles two semicircles joined by a rectangle, like a cricket infield, speed skating rink or an athletics track, however, this is more correctly called a stadium or archaically, an oblong. Sometimes, it can refer to any rectangle with rounded corners. The shape lends its name to many well-known places, ellipse Stadium Vesica piscis – a pointed oval

Water hyacinth
–
Eichhornia crassipes, commonly known as water hyacinth, is an aquatic plant native to the Amazon basin, and is often a highly problematic invasive species outside its native range. Water hyacinth is a perennial aquatic plant native to tropical and sub-tropical South America. With broad, thick, glossy, ovate leaves, water hyacinth may rise above the surface of the water as much as 1 meter in height, the leaves are 10–20 cm across, and float above the water surface. They have long, spongy and bulbous stalks, the feathery, freely hanging roots are purple-black. An erect stalk supports a single spike of 8-15 conspicuously attractive flowers, when not in bloom, water hyacinth may be mistaken for frogs-bit. One of the fastest growing plants known, water hyacinth reproduces primarily by way of runners or stolons, each plant additionally can produce thousands of seeds each year, and these seeds can remain viable for more than 28 years. Some water hyacinths were found to grow up to 2 to 5 metres a day in some sites in Southeast Asia, the common water hyacinth are vigorous growers known to double their population in two weeks. In their native range these flowers are pollinated by long tongued bees, the invasiveness of the hyacinth is related to its ability to clone itself and large patches are likely to all be part of the same genetic form. There are three morphs of water hyacinth, long medium and short, however, the short morph is restricted to the native range due to founder events during its distribution. Its habitat ranges from desert to subtropical or warm temperate desert to rainforest zones.0 to 7.5. It does not tolerate water temperatures >35 °C, leaves are killed by frost and salt water, the latter trait being used to kill some of it by floating rafts of the cut weed to the sea. Water hyacinths do not grow when the salinity is greater than 15% that of sea water. In brackish water, its leaves show epinasty and chlorosis, because of E. Neochetina eichhorniae causes a substantial reduction in water hyacinth production, it reduces plant height, weight, root length, and makes the plant produce fewer daughter plants. N. eichhorniae was introduced from Argentina to Florida in 1972, a semi-aquatic grasshopper, Cornops aquaticum, is being investigated in South Africa as an additional control agent. Azotobacter chroococcum, an N-fixing bacteria, is concentrated around the bases of the petioles. But the bacteria do not fix nitrogen unless the plant is suffering extreme N-deficiency and this plant is reported to contain HCN, alkaloid, and triterpenoid, and may induce itching. Plants sprayed with 2, 4-D may accumulate lethal doses of nitrates, Water hyacinth has been widely introduced in North America, Europe, Asia, Australia, Africa and New Zealand. In many areas it is has become an important and pernicious invasive species, in New Zealand it is listed on the National Pest Plant Accord which prevents it from being propagated, distributed or sold

Ibadan
–
Ibadan is the state capital of Oyo State, Nigeria. At the time Nigerias independence in 1960, Ibadan was the largest and most populous city in the country, and the second most populous in Africa after Cairo. Ibadan had been the centre of administration of the old Western Region since the days of the British colonial rule, the principal inhabitants of the city are the Yorubas, as well as various communities from other parts of the country. Ibadan came into existence in 1829, during a period of turmoil that characterized Yorubaland at the time. It was in period that many old Yoruba cities such as old Oyo, Ijaye and Owu disappeared. According to local historians, Lagelu founded the city, and was intended to be a war camp for warriors coming from Oyo, Ife. As a forest site containing several ranges of hills, varying in elevation from 160 to 275 metres, moreover, its location at the fringe of the forest promoted its emergence as a marketing centre for traders and goods from both the forest and grassland areas. In 1852 the Church Missionary Society sent David and Anna Hinderer to found a mission and they decided to build the mission and a church in Ibadan when they arrived in 1853. Ibadan thus had initially began as a state and remained so until the last decade of the 19th century. The city-state also succeeded in building an empire from the 1860s to the 1890s which extended over much of northern and eastern Yorubaland. It was appropriately nicknamed idi Ibon or “gun base”, because of its military character. Unlike other Yoruba cities with traditional kingship institutions however, In Ibadan, the then Alaafin of Oyo had ordered the old city destroyed for the act. Lagelu was by now an old, frail man, he could not stop the destruction of his city, but he and some of his people survived the attack and fled to a nearby hill for sanctuary. On the hill they survived by eating oro fruit and snails, later, they cultivated the land and made corn and millets into pap meals known as oori or eko and they improvised a bit by using the snail shells to drink the liquefied eko. Ultimately, Lagelu and his people came down from the hill and founded another city, the new city instantly grew prosperous and became a commercial nerve centre. Shortly afterwards, Lagelu died, leaving behind a politically savvy people, the newly enthroned Olubadan made a friendly gesture to the Olowu of Owu by allowing Olowu to marry his only daughter, Nkan. A part of Ibadan was historically an Egba town, the Egba occupants were forced to leave the town and moved to present-day Abeokuta under the leadership of Sodeke as result of their disloyalty. Ibadan grew into an impressive and sprawling urban center so much that by the end of 1829, the military sanctuary expanded even further when refugees began arriving in large numbers from northern Oyo following raids by Fulani warriors

Dye
–
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. Both dyes and pigments are colored because they absorb some wavelengths of light more than others, in contrast to dyes, pigments are insoluble and have no affinity for the substrate. Some dyes can be precipitated with a salt to produce a lake pigment. The majority of natural dyes are from plant sources, roots, berries, bark, leaves, and wood, fungi, textile dyeing dates back to the Neolithic period. Throughout history, people have dyed their textiles using common, locally available materials, scarce dyestuffs that produced brilliant and permanent colors such as the natural invertebrate dyes Tyrian purple and crimson kermes were highly prized luxury items in the ancient and medieval world. Plant-based dyes such as woad, indigo, saffron, and madder were raised commercially and were important trade goods in the economies of Asia, across Asia and Africa, patterned fabrics were produced using resist dyeing techniques to control the absorption of color in piece-dyed cloth. Dyes from the New World such as cochineal and logwood were brought to Europe by the Spanish treasure fleets, dyed flax fibers have been found in the Republic of Georgia in a prehistoric cave dated to 36,000 BP. Archaeological evidence shows that, particularly in India and Phoenicia, dyeing has been carried out for over 5,000 years. The dyes were obtained from animal, vegetable or mineral origin, by far the greatest source of dyes has been from the plant kingdom, notably roots, berries, bark, leaves and wood, but only a few have ever been used on a commercial scale. The discovery of synthetic dyes late in the 19th century ended the large-scale market for natural dyes. These dyes are made from synthetic resources such as petroleum by-products, the first human-made organic aniline dye, mauveine, was discovered serendipitously by William Henry Perkin in 1856, the result of a failed attempt at the total synthesis of quinine. Other aniline dyes followed, such as fuchsine, safranine, many thousands of synthetic dyes have since been prepared. These may be natural or synthetic, other than pigmentation, they have a range of applications including organic dye lasers, optical media and camera sensors. This is the basic classification Dyes are classified according to their solubility, acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber, acid dyes are not substantive to cellulosic fibers. Most synthetic food colors fall in this category, basic dyes are water-soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Usually acetic acid is added to the dye bath to help the uptake of the dye onto the fiber, basic dyes are also used in the coloration of paper

Civilization
–
Historically, a civilization was a so-called advanced culture in contrast to more supposedly primitive cultures. As an uncountable noun, civilization also refers to the process of a society developing into a centralized, urbanized, stratified structure, Civilization concentrates power, extending human control over the rest of nature, including over other human beings. The earlier neolithic technology and lifestyle was established first in the Middle East, and later in the Yangtze and Yellow River basins in China, similar pre-civilized neolithic revolutions also began independently from 7,000 BCE in such places as northwestern South America and Mesoamerica. These were among the six civilizations worldwide that arose independently, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BCE, with civilizations developing from 6,500 years ago. Towards the end of the Neolithic period, various elitist Chalcolithic civilizations began to rise in various cradles from around 3300 BCE. Chalcolithic civilizations, as defined above, also developed in Pre-Columbian Americas and, despite an early start in Egypt, Axum and Kush, the English word civilization comes from the 16th-century French civilisé, from Latin civilis, related to civis and civitas. The fundamental treatise is Norbert Eliass The Civilizing Process, which traces social mores from medieval courtly society to the Early Modern period, in The Philosophy of Civilization, Albert Schweitzer outlines two opinions, one purely material and the other material and ethical. Adjectives like civility developed in the mid-16th century, the abstract noun civilization, meaning civilized condition, came in the 1760s, again from French. The word was therefore opposed to barbarism or rudeness, in the pursuit of progress characteristic of the Age of Enlightenment. In the late 1700s and early 1800s, during the French revolution, civilization was used in the singular, never in the plural and this is still the case in French. The use of civilizations as a noun was in occasional use in the 19th century. Only in this sense does it become possible to speak of a medieval civilization. Already in the 18th century, civilization was not always seen as an improvement, one historically important distinction between culture and civilization is from the writings of Rousseau, particularly his work about education, Emile. From this, a new approach was developed, especially in Germany, first by Johann Gottfried Herder and this sees cultures as natural organisms, not defined by conscious, rational, deliberative acts, but a kind of pre-rational folk spirit. Civilization, in contrast, though more rational and more successful in material progress, is unnatural and leads to vices of social life such as guile, hypocrisy, envy and avarice. In World War II, Leo Strauss, having fled Germany, argued in New York that this opinion of civilization was behind Nazism, Social scientists such as V. Gordon Childe have named a number of traits that distinguish a civilization from other kinds of society. Andrew Nikiforuk argues that civilizations relied on shackled human muscle and it took the energy of slaves to plant crops, clothe emperors, and build cities and considers slavery to be a common feature of pre-modern civilizations. All civilizations have depended on agriculture for subsistence, grain farms can result in accumulated storage and a surplus of food, particularly when people use intensive agricultural techniques such as artificial fertilization, irrigation and crop rotation

Carbon dating
–
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed by Willard Libby in the late 1940s, Libby received the Nobel Prize for his work in 1960. The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with oxygen to form radioactive carbon dioxide. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died. The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained. Research has been ongoing since the 1960s to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the samples calendar age. Other corrections must be made to account for the proportion of 14C in different types of organisms, additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s. Conversely, nuclear testing increased the amount of 14C in the atmosphere, measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14C atoms in a sample. The development of dating has had a profound impact on archaeology. In addition to permitting more accurate dating within archaeological sites than previous methods, histories of archaeology often refer to its impact as the radiocarbon revolution. Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age, and they synthesized 14C using the laboratorys cyclotron accelerator and soon discovered that the atoms half-life was far longer than had been previously thought. This was followed by a prediction by Serge A. Korff, then employed at the Franklin Institute in Philadelphia and it had previously been thought that 14C would be more likely to be created by deuterons interacting with 13C. At some time during World War II, Willard Libby, who was then at Berkeley, learned of Korffs research, in 1945, Libby moved to the University of Chicago where he began his work on radiocarbon dating. He published a paper in 1946 in which he proposed that the carbon in living matter might include 14C as well as non-radioactive carbon, by contrast, methane created from petroleum showed no radiocarbon activity because of its age. The results were summarized in a paper in Science in 1947, Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages

Archeology
–
Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, Archaeology can be considered both a social science and a branch of the humanities. In North America, archaeology is considered a sub-field of anthropology, archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology as a field is distinct from the discipline of palaeontology, Archaeology is particularly important for learning about prehistoric societies, for whom there may be no written records to study. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies across the world, Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. The discipline involves surveying, excavation and eventually analysis of data collected to learn more about the past, in broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, Archaeology has been used by nation-states to create particular visions of the past. Nonetheless, today, archaeologists face many problems, such as dealing with pseudoarchaeology, the looting of artifacts, a lack of public interest, the science of archaeology grew out of the older multi-disciplinary study known as antiquarianism. Antiquarians studied history with attention to ancient artifacts and manuscripts. Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment era in Europe in the 17th and 18th centuries, in Europe, philosophical interest in the remains of Greco-Roman civilization and the rediscovery of classical culture began in the late Middle Age. Antiquarians, including John Leland and William Camden, conducted surveys of the English countryside, one of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey was a pioneer archaeologist who recorded numerous megalithic and other monuments in southern England. He was also ahead of his time in the analysis of his findings and he attempted to chart the chronological stylistic evolution of handwriting, medieval architecture, costume, and shield-shapes. Excavations were also carried out in the ancient towns of Pompeii and Herculaneum and these excavations began in 1748 in Pompeii, while in Herculaneum they began in 1738. The discovery of entire towns, complete with utensils and even human shapes, however, prior to the development of modern techniques, excavations tended to be haphazard, the importance of concepts such as stratification and context were overlooked. The father of archaeological excavation was William Cunnington and he undertook excavations in Wiltshire from around 1798, funded by Sir Richard Colt Hoare. Cunnington made meticulous recordings of neolithic and Bronze Age barrows, one of the major achievements of 19th century archaeology was the development of stratigraphy. The idea of overlapping strata tracing back to successive periods was borrowed from the new geological and paleontological work of scholars like William Smith, James Hutton, the application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites

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

Egypt
–
Egypt, officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. Egypt is a Mediterranean country bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba to the east, the Red Sea to the east and south, Sudan to the south, and Libya to the west. Across the Gulf of Aqaba lies Jordan, and across from the Sinai Peninsula lies Saudi Arabia, although Jordan and it is the worlds only contiguous Afrasian nation. Egypt has among the longest histories of any country, emerging as one of the worlds first nation states in the tenth millennium BC. Considered a cradle of civilisation, Ancient Egypt experienced some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. One of the earliest centres of Christianity, Egypt was Islamised in the century and remains a predominantly Muslim country. With over 92 million inhabitants, Egypt is the most populous country in North Africa and the Arab world, the third-most populous in Africa, and the fifteenth-most populous in the world. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres, the large regions of the Sahara desert, which constitute most of Egypts territory, are sparsely inhabited. About half of Egypts residents live in areas, with most spread across the densely populated centres of greater Cairo, Alexandria. Modern Egypt is considered to be a regional and middle power, with significant cultural, political, and military influence in North Africa, the Middle East and the Muslim world. Egypts economy is one of the largest and most diversified in the Middle East, Egypt is a member of the United Nations, Non-Aligned Movement, Arab League, African Union, and Organisation of Islamic Cooperation. Miṣr is the Classical Quranic Arabic and modern name of Egypt. The name is of Semitic origin, directly cognate with other Semitic words for Egypt such as the Hebrew מִצְרַיִם, the oldest attestation of this name for Egypt is the Akkadian

Middle East
–
The Middle East is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is Middle-Eastern and the noun is Middle-Easterner. The term has come into usage as a replacement of the term Near East beginning in the early 20th century. Arabs, Turks, Persians, Kurds, and Azeris constitute the largest ethnic groups in the region by population. Indigenous minorities of the Middle East include Jews, Assyrians and other Arameans, Baloch, Berbers, Copts, Druze, Lurs, Mandaeans, Samaritans, Shabaks, Tats, in the Middle East, there is also a Romani community. European ethnic groups form a diaspora in the region include Albanians, Bosniaks, Circassians, Crimean Tatars, Franco-Levantines. Among other migrant populations are Bengalis as well as other Indians, Chinese, Filipinos, Indonesians, Pakistanis, the history of the Middle East dates back to ancient times, with the importance of the region being recognized for millennia. Most of the countries border the Persian Gulf have vast reserves of crude oil. The term Middle East may have originated in the 1850s in the British India Office, however, it became more widely known when American naval strategist Alfred Thayer Mahan used the term in 1902 to designate the area between Arabia and India. During this time the British and Russian Empires were vying for influence in Central Asia, Mahan realized not only the strategic importance of the region, but also of its center, the Persian Gulf. Mahan first used the term in his article The Persian Gulf and International Relations, published in September 1902 in the National Review, a British journal. The Middle East, if I may adopt a term which I have not seen, will some day need its Malta, as well as its Gibraltar, it does not follow that either will be in the Persian Gulf. The British Navy should have the facility to concentrate in force if occasion arise, about Aden, India, mahans article was reprinted in The Times and followed in October by a 20-article series entitled The Middle Eastern Question, written by Sir Ignatius Valentine Chirol. During this series, Sir Ignatius expanded the definition of Middle East to include regions of Asia which extend to the borders of India or command the approaches to India. After the series ended in 1903, The Times removed quotation marks from subsequent uses of the term, in the late 1930s, the British established the Middle East Command, which was based in Cairo, for its military forces in the region. After that time, the term Middle East gained broader usage in Europe, the description Middle has also led to some confusion over changing definitions. Before the First World War, Near East was used in English to refer to the Balkans and the Ottoman Empire, while Middle East referred to Iran, the Caucasus, Afghanistan, Central Asia, and Turkestan. The first official use of the term Middle East by the United States government was in the 1957 Eisenhower Doctrine, the Associated Press Stylebook says that Near East formerly referred to the farther west countries while Middle East referred to the eastern ones, but that now they are synonymous

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

Kiln
–
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles, various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many other materials. The word kiln descends from the Old English cylene (/ˈkylene/, which was adapted from the Latin culīna kitchen, cooking-stove, burning-place. During the Middle English Period, the n was not pronounced, as evidenced by kiln having frequently been spelled without the n, Another word, miln, a place where wheat is ground, also had a silent n. Whereas the spelling of miln was changed to mill to match its pronunciation, kiln maintained its spelling, which most likely led to a common mispronunciation, however, there are small bastions where the original pronunciation has endured. Kiln, Mississippi, a town known for its wood drying kilns that once served the timber industry, is still referred to as the Kill by locals. Unwittingly adding the n sound at the end of kiln is due to people being introduced to the word through the language before ever hearing the actual pronunciation. Phonetically, the ln in kiln is categorized as a digraph, from English Words as Spoken and Written for Upper Grades by James A. Bowen 1900, The digraph ln, n silent, occurs in kiln. A fall down the kiln can kill you, Bowen was pointing out the humorous fact that kill and kiln are homophones. A homophone is a word that is pronounced the same as another word but differs in meaning, the earliest known kiln dates to around 6000 BC, and was found at the Yarim Tepe site in modern Iraq. Neolithic kilns were able to produce greater than 900 °C. Ceramics require heat at high temperatures so chemical and physical reactions will occur to permanently alter the unfired body, in the case of pottery, clay materials are shaped, dried and then fired in a kiln. The final characteristics are determined by the composition and preparation of the clay body, after a first firing glazes may be used and the ware is fired a second time to fuse the glaze into the body. A third firing at a lower temperature may be required to fix overglaze decoration, modern kilns often have sophisticated electrical control systems to firing regime, although pyrometric devices are often also used. Clay consists of fine-grained particles, that are weak and porous. Clay is combined with other minerals to create a clay body. Part of the process includes sintering. This heats the clay until the particles partially melt and flow together, creating a strong, single mass, composed of a glassy phase interspersed with pores, through firing, the pores are reduced in size, causing the material to shrink slightly

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

Factory
–
Factories arose with the introduction of machinery during the Industrial Revolution when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called glorified workshops, most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, with some having rail, highway, factories may either make discrete products or some type of material continuously produced such as chemicals, pulp and paper, or refined oil products. Oil refineries have most of their equipment outdoors, discrete products may be final consumer goods, or parts and sub-assemblies which are made into final products elsewhere. Factories may be supplied parts from elsewhere or make them from raw materials, continuous production industries typically use heat or electricity to transform streams of raw materials into finished products. The term mill originally referred to the milling of grain, which usually used natural resources such as water or wind power until those were displaced by steam power in the 19th century. Because many processes like spinning and weaving, iron rolling, and paper manufacturing were originally powered by water, according to translations of Demosthenes and Herodotus, Naucratis was a, or the only, factory in the entirety of ancient Egypt. A source of 1983, states the largest factory production in ancient times was of 120 slaves within 4th century BC Athens, although The Cambridge Online Dictionary definition of factory states, a building or set of buildings where large amounts of goods are made using machines elsewhere. The wheel was invented circa 3000 BC, the spoked wheel c.2000 BC, the Iron Age began approximately 1200-1000 BC. However, other sources define machinery as a means of production, according to one text the water-mill was first made in 555 A. D. by Belisarius, although according to another they were known to Pliny the Elder and Vitruvius in the first century B. C. By the time of the 4th century A. D. mills with a capacity to grind 3 tonnes of cereal an hour, the Venice Arsenal provides one of the first examples of a factory in the modern sense of the word. Founded in 1104 in Venice, Republic of Venice, several hundred years before the Industrial Revolution, the Venice Arsenal apparently produced nearly one ship every day and, at its height, employed 16,000 people. One of the earliest factories was John Lombes water-powered silk mill at Derby, by 1746, an integrated brass mill was working at Warmley near Bristol. Raw material went in at one end, was smelted into brass and was turned into pans, pins, wire, housing was provided for workers on site. Josiah Wedgwood in Staffordshire and Matthew Boulton at his Soho Manufactory were other prominent early industrialists, the factory system began widespread use somewhat later when cotton spinning was mechanized. Richard Arkwright is the credited with inventing the prototype of the modern factory. After he patented his water frame in 1769, he established Cromford Mill, in Derbyshire, England, the factory system was a new way of organizing labour made necessary by the development of machines which were too large to house in a workers cottage. Working hours were as long as they had been for the farmer, overall, this practice essentially reduced skilled and unskilled workers to replaceable commodities

Wicker
–
Wicker is a kind of furniture woven from any one of a variety of cane-like materials, including rattan, willow, reed and bamboo. As such, it is not a material, but a technique. The word wicker is believed to be of Scandinavian origin, wika which means to bend in Swedish, Wicker is traditionally made of material of plant origin, but plastic fibers are now also used. Wicker is light yet sturdy, making it suitable for furniture that will be moved often like porch, a variety of plants are used such as reeds, grasses, creepers, and thin tree branches. Rushwork and wickerwork are terms used in England, Wicker has been documented as far back as ancient Egypt, made from indigenous reed and swamp grasses. Middle-class families could afford a few pieces, such as small tables. However, archaeologists working on the tombs of the wealthy pharaohs have uncovered a variety of wicker items, including chests, baskets, wig boxes. Wicker even found use in the Achaemenid Empire on the battlefield, the popularity of wicker passed from ancient Egypt and Persia to ancient Rome. Wicker baskets were used to carry items in Pompeii, furniture was manufactured out of wicker in the Roman style. It has been proposed that the use of wicker in the Iron Age may have influenced the development of the woven patterns used in Celtic art. By the 16th and 17th centuries, wicker was quite common in European countries like Portugal, Spain, Wicker received a boost during the Age of Exploration, when international sea traders returned from southeast Asia with a species of palm called rattan. Rattan is stronger than traditional European wicker materials, although the stem can be separated so the softer inner core can be used for wicker. The 19th century brought immense popularity for wicker in Europe, England and it was used outdoors as well as indoors. People in the Victorian Era believed it to be more sanitary than upholstered furniture and it was inexpensive, resisted harsh weather and was adaptable to many styles. In the United States, Cyrus Wakefield began constructing rattan furniture in the 1850s and he first used rattan that had been offloaded from ships, where it was used as ballast, but as his designs became well-known, he began importing the material himself. In recent times, its aesthetic was influenced heavily by the Arts and Crafts movement at the turn of the 20th century, Wicker is still a popular material. Antique wicker products are sought after by collectors. Reproductions of furniture and accent pieces are sold for indoor and outdoor use

Victorian era
–
The Victorian era was the period of Queen Victorias reign, from 20 June 1837 until her death on 22 January 1901. It was a period of peace, prosperity, refined sensibilities. Some scholars date the beginning of the period in terms of sensibilities, the era followed the Georgian period and preceded the Edwardian period. The later half of the Victorian age roughly coincided with the first part of the Belle Époque era of continental Europe, culturally there was a transition away from the rationalism of the Georgian period and toward romanticism and mysticism with regard to religion, social values, and arts. The end of the saw the Boer War. Domestically, the agenda was increasingly liberal with a number of shifts in the direction of political reform, industrial reform. Two especially important figures in period of British history are the prime ministers Benjamin Disraeli and William Gladstone. Disraeli, favoured by the queen, was a gregarious Conservative and his rival Gladstone, a Liberal distrusted by the Queen, served more terms and oversaw much of the overall legislative development of the era. The population of England and Wales almost doubled from 16.8 million in 1851 to 30.5 million in 1901, Scotlands population also rose rapidly, from 2.8 million in 1851 to 4.4 million in 1901. However, Irelands population decreased sharply, from 8.2 million in 1841 to less than 4.5 million in 1901, mostly due to the Great Famine. Between 1837 and 1901 about 15 million emigrants departed the UK permanently, in search of a life in the United States, Canada, South Africa, New Zealand, Australia. During the early part of the era, politics in the House of Commons involved battles between the two parties, the Whigs/Liberals and the Conservatives. These parties were led by such prominent statesmen as Lord Melbourne, Sir Robert Peel, Lord Derby, Lord Palmerston, Gladstone, Disraeli, Victoria became queen in 1837 at age 18. Her long reign until 1901 was mainly a time of peace, Britain reached the zenith of its economic, political, diplomatic and cultural power. The era saw the expansion of the second British Empire, Historians have characterised the mid-Victorian era as Britains Golden Years. There was prosperity, as the income per person grew by half. There was peace abroad, and social peace at home, opposition to the new order melted away, says Porter. The Chartist movement peaked as a movement among the working class in 1848, its leaders moved to other pursuits, such as trade unions

War pigeon
–
Pigeons have long played an important role in war. Due to their ability, speed, and altitude, they were often used as military messengers. Carrier pigeons of the Racing Homer breed were used to carry messages in World War I and World War II and they ceased being used as of 1957. During the First and Second World Wars, carrier pigeons were used to transport back to their home coop behind the lines. When they landed, wires in the coop would sound a bell or buzzer and he would go to the coop, remove the message from the canister, and send it to its destination by telegraph, field phone, or personal messenger. A carrier pigeons job was dangerous, nearby enemy soldiers often tried to shoot down pigeons, knowing that released birds were carrying important messages. Some of these pigeons became quite famous among the infantrymen they worked for, one pigeon, named The Mocker, flew 52 missions before he was wounded. Another, named Cher Ami, lost her foot and one eye, before the advent of radio, carrier pigeons were frequently used on the battlefield as a means for a mobile force to communicate with a stationary headquarters. In the 6th century BC, Cyrus, king of Persia, in Ancient Rome, within many texts, there are references to pigeons being used to send messages by Julius Caesar. The French military used balloons to transport homing pigeons past enemy lines, microfilm images containing hundreds of messages allowed letters to be carried into Paris by pigeon from as far away as London. More than one million different messages travelled this way during the four-month siege and they were then discovered to be very useful, and carrier pigeons were well considered in military theory leading up to World War I. Homing pigeons were used extensively during World War I, in 1914 during the First Battle of the Marne, the French army advanced 72 pigeon lofts with the troops. The US Army Signal Corps used 600 pigeons in France alone, one of their homing pigeons, a Blue Check hen named Cher Ami, was awarded the French Croix de Guerre with Palm for heroic service delivering 12 important messages during the Battle of Verdun. On her final mission in October 1918, she delivered a message despite having been shot through the breast or wing, the crucial message, found in the capsule hanging from a ligament of her shattered leg, saved 194 US soldiers of the 77th Infantry Divisions Lost Battalion. United States Navy aviators maintained 12 pigeon stations in France with an inventory of 1,508 pigeons when the war ended. Pigeons were carried in airplanes to rapidly return messages to these stations, eleven of the thrown pigeons went missing in action, but the remaining 219 messages were delivered successfully. The pigeons were trained at the Norfolk Naval Shipyard while Langley was undergoing conversion, the pigeons never went to sea again. During World War II, the United Kingdom used about 250,000 homing pigeons for many purposes, the Dickin Medal, the highest possible decoration for valor given to animals, was awarded to 32 pigeons, including the United States Army Pigeon Services G. I

Ammunition
–
Ammunition is the general term used for the material fired, scattered, dropped or detonated from any weapon. The term ammunition can be traced back to the mid 17th century, broadly speaking, ammunition refers to both expendable weapons and the component parts of other weapons that create the effect on a target. Nearly all weapons will require some form of ammunition to operate, the word comes from the French la munition, which refers to the material used for war. The terms ammunition and munitions are used interchangeably, although the term munition now usually refers to both the actual weapons system alongside the ammunition required to operate it. The purpose of ammunition is to project a force against a target to have an effect. The most iconic example of ammunition is the cartridge, which all components required to deliver the weapon effect in a single package. Ammunition comes in a range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain types that enable their use across different weapons. There are also types of ammunition that are designed to have a specialized effect on a target, such as armor-piercing shells and tracer ammunition. Ammunition is commonly colored in a manner to assist in the identification. A round is a cartridge containing a projectile, propellant, primer. A shell is a form of ammunition that is fired by a large cannon or artillery piece. Before the mid-19th century, these shells were made of solid materials. However, since that time, they are often filled with high-explosives. A shot refers to a release of a weapons system. This may involve firing just one round or piece of ammunition, a dud refers to loaded ammunition that fails to function as intended, typically failing to detonate on landing. However, it can refer to ammunition that fails to fire inside the weapon, known as a misfire, or when the ammunition only partially functions. Dud ammunition, which is classified as an ordnance, is regarded as highly dangerous

Infantry
–
Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare, Infantry can enter and maneuver in terrain that is inaccessible to military vehicles and employ crew-served infantry weapons that provide greater and more sustained firepower. In English, the 16th-century term Infantry describes soldiers who walk to the battlefield, and there engage, fight, the term arose in Sixteenth-Century Spain, which boasted one of the first professional standing armies seen in Europe since the days of Rome. It was common to appoint royal princes to military commands, and the men under them became known as Infanteria. in the Canadian Army, the role of the infantry is to close with, and destroy the enemy. In the U. S. Army, the closes with the enemy, by means of fire and maneuver, in order to destroy or capture him, or to repel his assault by fire, close combat. In the U. S. Marine Corps, the role of the infantry is to locate, close with, and destroy the enemy fire and maneuver. Beginning with the Napoleonic Wars of the early 19th century, artillery has become a dominant force on the battlefield. Since World War I, combat aircraft and armoured vehicles have become dominant. In 20th and 21st century warfare, infantry functions most effectively as part of a combined arms team including artillery, armour, Infantry relies on organized formations to be employed in battle. These have evolved over time, but remain a key element to effective infantry development and deployment, until the end of the 19th century, infantry units were for the most part employed in close formations up until contact with the enemy. This allowed commanders to control of the unit, especially while maneuvering. The development of guns and other weapons with increased firepower forced infantry units to disperse in order to make them less vulnerable to such weapons. This decentralization of command was made possible by improved communications equipment, among the various subtypes of infantry is Medium infantry. This refers to infantry which are heavily armed and armored than heavy infantry. In the early period, medium infantry were largely eliminated due to discontinued use of body armour up until the 20th century. In the United States Army, Stryker Infantry is considered Medium Infantry, since they are heavier than light infantry, Infantry doctrine is the concise expression of how infantry forces contribute to campaigns, major operations, battles, and engagements. It is a guide to action, not a set of hard, doctrine provides a very common frame of reference across the military forces, allowing the infantry to function cooperatively in what are now called combined arms operations. Doctrine helps standardise operations, facilitating readiness by establishing common ways of accomplishing infantry tasks, doctrine links theory, history, experimentation, and practice
