Nepal
–
Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked central Himalayan country in South Asia. Nepal is divided into 7 provinces and 75 districts and 744 local units including 4 metropolises,13 sub-metropolises,246 municipal councils and 481 village and it has a population of 26.4 million and is the 93rd largest country by area. Bordering China in the north and India in the south, east, Nepal does not border Bangladesh, which is located within only 27 km of its southeastern tip. It neither borders Bhutan due to the Indian state of Sikkim being located in between, Nepal has a diverse geography, including fertile plains, subalpine forested hills, and eight of the worlds ten tallest mountains, including Mount Everest, the highest point on Earth. Kathmandu is the capital and largest city. It is a nation with Nepali as the official language. The territory of Nepal has a history since the Neolithic age. The name Nepal is first recorded in texts from the Vedic Age, the era which founded Hinduism, in the middle of the first millennium BCE, Gautama Buddha, the founder of Buddhism, was born in southern Nepal. Parts of northern Nepal were intertwined with the culture of Tibet, the Kathmandu Valley in central Nepal became known as Nepal proper because of its complex urban civilization. It was the seat of the prosperous Newar confederacy known as Nepal Mandala, the Himalayan branch of the ancient Silk Road was dominated by the valleys traders. The cosmopolitan region developed distinct traditional art and architecture, by the 18th century, the Gorkha Kingdom achieved the unification of Nepal. The Shah dynasty established the Kingdom of Nepal and later formed an alliance with the British Empire, the country was never colonized but served as a buffer state between Imperial China and Colonial India. In the 20th century, Nepal ended its isolation and forged ties with regional powers. Parliamentary democracy was introduced in 1951, but was suspended by Nepalese monarchs in 1960 and 2005. The Nepalese Civil War resulted in the proclamation of a republic in 2008, modern Nepal is a federal secular parliamentary republic. Nepal is a nation, ranking 144th on the Human Development Index in 2016. The country struggles with the transition from a monarchy to a republic and it also suffers from high levels of hunger and poverty. Despite these challenges, Nepal is making progress, with the government declaring its commitment to elevate the nation from least developed country status by 2022

Coin
–
A coin is a small, flat, round piece of metal or plastic used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in quantities at a mint in order to facilitate trade. They are most often issued by a government, Coins are usually metal or alloy, or sometimes made of synthetic materials. Coins made of metal are stored in large quantities as bullion coins. Other coins are used as money in transactions, circulating alongside banknotes. Usually the highest value coin in circulation is less than the lowest-value note. In the last hundred years, the value of circulation coins has occasionally been lower than the value of the metal they contain. Exceptions to the rule of face value being higher than content value also occur for some bullion coins made of copper, silver, or gold, while the Eagle, Maple Leaf, and Sovereign coins have nominal face values, the Krugerrand does not. The first coins were developed independently in Iron Age Anatolia and Archaic Greece, India, Coins spread rapidly in the 6th and 5th centuries BCE, throughout Greece and Persia, and further to the Balkans. Standardized Roman currency was used throughout the Roman Empire, important Roman gold and silver coins were continued into the Middle Ages. Fiat money first arose in medieval China, with the paper money. Early paper money was introduced in Europe in the later Middle Ages, the penny was minted as a silver coin until the 17th century. The first circulating United States coins were cents, produced in 1793, Coins were an evolution of currency systems of the Late Bronze Age, where standard-sized ingots, and tokens such as knife money, were used to store and transfer value. In the late Chinese Bronze Age, standardized cast tokens were made and these were replicas in bronze of earlier Chinese currency, cowrie shells, so they were named Bronze Shell. According to Aristotle and Pollux, the first issuer of coins was Hermodike of Kyme The earliest coins are associated with Iron Age Anatolia. Early electrum coins were not standardized in weight, and in their earliest stage may have been ritual objects, such as badges or medals, issued by priests. The first Lydian coins were made of electrum, a naturally occurring alloy of silver, most of the early Lydian coins include no writing, only an image of a symbolic animal. Anatolian Artemis was the Πὀτνια Θηρῶν, whose symbol was the stag, a small percentage of early Lydian/Greek coins have a legend

Child
–
Biologically, a child is a human being between the stages of birth and puberty. The legal definition of child generally refers to a minor, otherwise known as a younger than the age of majority. There are many issues that affect children, such as childhood education, bullying, child poverty, dysfunctional families, child labor, hunger. Children can be raised by parents, by fosterers, guardians or partially raised in a day care center. The United Nations Convention on the Rights of the Child defines child as a human being below the age of 18 years unless under the law applicable to the child and this is ratified by 192 of 194 member countries. Biologically, a child is generally anyone between birth and puberty, some English definitions of the word child include the fetus. In many cultures, a child is considered an adult after undergoing a rite of passage, recognition of childhood as a state different from adulthood began to emerge in the 16th and 17th centuries. Society began to relate to the not as a miniature adult but as a person of a lower level of maturity needing adult protection, love. This change can be traced in paintings, In the Middle Ages, in the 16th century, images of children began to acquire a distinct childlike appearance. From the late 17th century onwards, children were playing with toys. Every child goes through stages of social development. An infant or very young child will play alone happily, if another child wanders onto the scene, he or she may be physically attacked or pushed out of the way. Next, the child can play with another child, gradually learning to share, eventually, the group grows larger, to three or four children. By the time a child enters kindergarten, he or she can join in. Children with ADHD and learning disabilities may need help to develop social skills. The impulsive characteristics of an ADHD child may lead to poor peer relationships, children with poor attention spans may not tune into social cues in their environment, making it difficult for them to learn social skills through experience. The age at which children are considered responsible for their society-bound actions has changed over time. In Roman times, children were regarded as not culpable for crimes, in the 19th century, children younger than seven years old were believed incapable of crime

Pig
–
A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar, along with species, related creatures outside the genus include the peccary, the babirusa. Pigs, like all suids, are native to the Eurasian and African continents, juvenile pigs are known as piglets. Pigs are highly social and intelligent animals, with around 1 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet. Pigs are omnivores and can consume a range of food. Pigs can harbour a range of parasites and diseases that can be transmitted to humans, because of the similarities between pigs and humans, pigs are used for human medical research. The Online Etymology Dictionary provides anecdotal evidence as well as linguistic, saying that the term derives probably from Old English *picg, found in compounds, apparently related to Low German bigge, Dutch big. Another Old English word for pig was fearh, related to furh furrow, from PIE *perk- dig and this reflects a widespread IE tendency to name animals from typical attributes or activities. Synonyms grunter, porker are from sailors and fishermens euphemistic avoidance of uttering the word pig at sea, a superstition perhaps based on the fate of the Gadarene swine and it is entirely likely that the word to call pigs, soo-ie, is similarly derived. A typical pig has a head with a long snout which is strengthened by a special prenasal bone. The snout is used to dig into the soil to find food and is an acute sense organ. There are four hoofed toes on each trotter, with the two larger central toes bearing most of the weight, but the two also being used in soft ground. The dental formula of adult pigs is 3.1.4.33.1.4.3, the rear teeth are adapted for crushing. In the male, the teeth form tusks, which grow continuously and are sharpened by constantly being ground against each other. Occasionally, captive mother pigs may savage their own piglets, often if they become severely stressed, some attacks on newborn piglets are non-fatal. Others may cause the death of the piglets and sometimes, the mother may eat the piglets and it is estimated that 50% of piglet fatalities are due to the mother attacking, or unintentionally crushing, the newborn pre-weaned animals. Scientists have recently discovered that pigs can exhibit a bias and are optimists or pessimests. In a study by the University of Lincoln,36 pigs were tested and they were placed in a room with two food bowls at each end of the room

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

Porcelain
–
Porcelain /ˈpɔːrsəlᵻn, ˈpɔːrslᵻn/ is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C. Porcelain was first developed in China around 2,000 years ago, then spread to other East Asian countries, and finally Europe. It combines well with both glazes and paint, and can be modelled very well, allowing a range of decorative treatments in tablewares, vessels. It also has uses in technology and industry. The European name, porcelain in English, come from the old Italian porcellana because of its resemblance to the translucent surface of the shell, Porcelain is also referred to as china or fine china in some English-speaking countries, as it was first seen in imports from China. Porcelain has been described as being completely vitrified, hard, impermeable, white or artificially coloured, translucent, however, the term porcelain lacks a universal definition and has been applied in a very unsystematic fashion to substances of diverse kinds which have only certain surface-qualities in common. Terms such as porcellaneous or near-porcelain may be used in such cases, a high proportion of modern porcelain is made of the variant bone china. Kaolin is the material from which porcelain is made, even though clay minerals might account for only a small proportion of the whole. The word paste is an old term for both the unfired and fired material, a more common terminology these days for the unfired material is body, for example, when buying materials a potter might order an amount of porcelain body from a vendor. The composition of porcelain is highly variable, but the mineral kaolinite is often a raw material. Other raw materials can include feldspar, ball clay, glass, bone ash, steatite, quartz, petuntse, the clays used are often described as being long or short, depending on their plasticity. Long clays are cohesive and have high plasticity, short clays are cohesive and have lower plasticity. Clays used for porcelain are generally of lower plasticity and are shorter than many other pottery clays and they wet very quickly, meaning that small changes in the content of water can produce large changes in workability. Thus, the range of content within which these clays can be worked is very narrow. The following section provides information on the methods used to form, decorate, finish, glaze. Many types of glaze, such as the iron-containing glaze used on the wares of Longquan, were designed specifically for their striking effects on porcelain. Porcelain wares may be decorated under the glaze using pigments that include cobalt and copper or over the glaze using coloured enamels. Like many earlier wares, modern porcelains are often biscuit-fired at around 1,000 °C, coated with glaze, another early method is once-fired where the glaze is applied to the unfired body and the two fired together in a single operation
