Trepanning
–
It may also refer to any burr hole created through other body surfaces, including nail beds. It is often used to relieve pressure beneath a surface, a trephine is an instrument used for cutting out a round piece of skull bone. In ancient times, holes were drilled into a person who was behaving in what was considered a way to let out what they believed were evil spirits. Evidence of trepanation has been found in human remains from Neolithic times onward. Cave paintings indicate that people believed the practice would cure epileptic seizures, migraines, the bone that was trepanned was kept by the prehistoric people and may have been worn as a charm to keep evil spirits away. Such injuries were typical for primitive weaponry such as slings and war clubs, there is some contemporary use of the term. In modern eye surgery, an instrument is used in corneal transplant surgery. The procedure of drilling a hole through a fingernail or toenail is also known as trephination, trepanation is perhaps the oldest surgical procedure for which there is archaeological evidence, and in some areas may have been quite widespread. At one burial site in France dated to 6500 BC,40 out of 120 prehistoric skulls found had trepanation holes, many prehistoric and premodern patients had signs of their skull structure healing, suggesting that many of those subjected to the surgery survived. Another skull with a hole was found at burial site Chalaghantepe dated to the 5th millennium BC. More than 1500 trephined skulls from the Neolithic period have been uncovered throughout the world – from Europe, Siberia, China, most of the trephined crania belong to adult males, but women and children are also represented. It has also found in the Muisca Confederation and the Inca Empire. Its prevalence among Mesoamerican civilizations is much lower, at least judging from the comparatively few trepanated crania that have been uncovered, several Mesoamerican cultures used a skull-rack, on which skulls were impaled in rows or columns of wooden stakes. Even so, some evidence of trepanation in Mesoamerica has survived. Later studies documented cases identified from a range of sites in Oaxaca and central Mexico, such as Tilantongo, Oaxaca, two specimens from the Tlatilco civilizations homelands indicate the practice has a lengthy tradition. Instead, the pre-Columbian Maya apparently used a technique that ground away at the back of the skull, thinning the bone and sometimes perforating it. Trepanation was also practiced in the classical and Renaissance periods, hippocrates gave specific directions on the procedure from its evolution through the Greek age, and Galen also elaborates on the procedure. During the Middle Ages and the Renaissance, trepanation was practiced as a cure for ailments, including seizures

Medicine
–
Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. The word medicine is derived from Latin medicus, meaning a physician, Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Medicine has existed for thousands of years, during most of which it was an art frequently having connections to the religious and philosophical beliefs of local culture. For example, a man would apply herbs and say prayers for healing, or an ancient philosopher. In recent centuries, since the advent of modern science, most medicine has become a combination of art, while stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science. Prescientific forms of medicine are now known as medicine and folk medicine. They remain commonly used with or instead of medicine and are thus called alternative medicine. For example, evidence on the effectiveness of acupuncture is variable and inconsistent for any condition, in contrast, treatments outside the bounds of safety and efficacy are termed quackery. Medical availability and clinical practice varies across the world due to differences in culture. In modern clinical practice, physicians personally assess patients in order to diagnose, treat, the doctor-patient relationship typically begins an interaction with an examination of the patients medical history and medical record, followed by a medical interview and a physical examination. Basic diagnostic medical devices are typically used, after examination for signs and interviewing for symptoms, the doctor may order medical tests, take a biopsy, or prescribe pharmaceutical drugs or other therapies. Differential diagnosis methods help to rule out conditions based on the information provided, during the encounter, properly informing the patient of all relevant facts is an important part of the relationship and the development of trust. The medical encounter is then documented in the record, which is a legal document in many jurisdictions. Follow-ups may be shorter but follow the general procedure. The diagnosis and treatment may take only a few minutes or a few weeks depending upon the complexity of the issue, the components of the medical interview and encounter are, Chief complaint, the reason for the current medical visit. They are in the patients own words and are recorded along with the duration of each one, also called chief concern or presenting complaint. History of present illness, the order of events of symptoms. Distinguishable from history of illness, often called past medical history

Invention
–
An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process and it may be an improvement upon a machine or product or a new process for creating an object or a result. An invention that achieves a unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field, an inventor may be taking a big step in success or failure. A patent legally protects the property rights of the inventor. The rules and requirements for patenting an invention vary from country to country, another meaning of invention is cultural invention, which is an innovative set of useful social behaviours adopted by people and passed on to others. The Institute for Social Inventions collected many such ideas in magazines, Invention is also an important component of artistic and design creativity. Inventions often extend the boundaries of knowledge, experience or capability. Brainstorming also can spark new ideas for an invention, collaborative creative processes are frequently used by engineers, designers, architects and scientists. Co-inventors are frequently named on patents, in addition, many inventors keep records of their working process - notebooks, photos, etc. including Leonardo da Vinci, Galileo Galilei, Evangelista Torricelli, Thomas Jefferson and Albert Einstein. In the process of developing an invention, the idea may change. The invention may become simpler, more practical, it may expand, working on one invention can lead to others too. History shows that turning the concept of an invention into a device is not always swift or direct. Inventions may also more useful after time passes and other changes occur. For example, the became more useful once powered flight was a reality. Invention is often a creative process, an open and curious mind allows an inventor to see beyond what is known. Seeing a new possibility, connection, or relationship can spark an invention, inventive thinking frequently involves combining concepts or elements from different realms that would not normally be put together. Sometimes inventors disregard the boundaries between distinctly separate territories or fields, several concepts may be considered when thinking about invention

Writing
–
Writing is a medium of human communication that represents language and emotion through the inscription or recording of signs and symbols. In most languages, writing is a complement to speech or spoken language, Writing is not a language but a form of technology that developed as tools developed with human society. Within a language system, writing relies on many of the structures as speech, such as vocabulary, grammar and semantics. The result of writing is called text, and the recipient of text is called a reader. Motivations for writing include publication, storytelling, correspondence and diary, Writing has been instrumental in keeping history, maintaining culture, dissemination of knowledge through the media and the formation of legal systems. As human societies emerged, the development of writing was driven by pragmatic exigencies such as exchanging information, maintaining financial accounts, codifying laws, in both ancient Egypt and Mesoamerica writing may have evolved through calendrics and a political necessity for recording historical and environmental events. H. G. Wells argued that writing has the ability to put agreements, laws and it made the growth of states larger than the old city states possible. It made a continuous historical consciousness possible, the command of the priest or king and his seal could go far beyond his sight and voice and could survive his death. The major writing systems—methods of inscription—broadly fall into four categories, logographic, syllabic, alphabetic, another category, ideographic, has never been developed sufficiently to represent language. A sixth category, pictographic, is insufficient to represent language on its own, a logogram is a written character which represents a word or morpheme. A vast number of logograms are needed to write Chinese characters, cuneiform, and Mayan, where a glyph may stand for a morpheme, many logograms have an ideographic component. For example, in Mayan, the glyph for fin, pronounced ka, was used to represent the syllable ka whenever the pronunciation of a logogram needed to be indicated. In Chinese, about 90% of characters are compounds of an element called a radical with an existing character to indicate the pronunciation. However, such phonetic elements complement the elements, rather than vice versa. A syllabary is a set of symbols that represent syllables. A glyph in a syllabary typically represents a consonant followed by a vowel, or just a vowel alone, phonetically related syllables are not so indicated in the script. For instance, the syllable ka may look nothing like the syllable ki, syllabaries are best suited to languages with a relatively simple syllable structure, such as Japanese. Other languages that use syllabic writing include the Linear B script for Mycenaean Greek, Cherokee, Ndjuka, an English-based creole language of Surinam, most logographic systems have a strong syllabic component

History of medicine
–
The history of medicine, as practiced by trained professionals, shows how societies have changed in their approach to illness and disease from ancient times to the present. Early medical traditions include those of Babylon, China, Egypt, Greece, Rest of Africa, the Greeks introduced the concepts of medical diagnosis, prognosis, and advanced medical ethics. The Hippocratic Oath, still taken by doctors up to today, was written in Greece in the 5th century BCE, in the medieval age, surgical practices inherited from the ancient masters were improved and then systematized in Rogeriuss The Practice of Surgery. Universities began systematic training of physicians around the years 1220 in Italy, during the Renaissance, understanding of anatomy improved, and the microscope was invented. The germ theory of disease in the 19th century led to cures for many infectious diseases, military doctors advanced the methods of trauma treatment and surgery. Public health measures were developed especially in the 19th century as the growth of cities required systematic sanitary measures. Advanced research centers opened in the early 20th century, often connected with major hospitals, the mid-20th century was characterized by new biological treatments, such as antibiotics. These advancements, along with developments in chemistry, genetics, Medicine was heavily professionalized in the 20th century, and new careers opened to women as nurses and as physicians. The 21st century is characterized by highly advanced research involving numerous fields of science, although there is no record to establish when plants were first used for medicinal purposes, the use of plants as healing agents, as well as clays and soils is ancient. Over time through emulation of the behavior of fauna a medicinal knowledge base developed and passed between generations, as tribal culture specialized specific castes, shamans and apothecaries fulfilled the role of healer. The first known dentistry dates to about 7,000 B. C. E. in Baluchistan, the first known trepanning operation was carried out about 5,000 B. C. E. in Ensisheim, France. The earliest known surgery, an amputation was carried out about 4,900 B. C. E. in Buthiers-Bulancourt, Ancient Egypt developed a large, varied and fruitful medical tradition. Herodotus described the Egyptians as the healthiest of all men, next to the Libyans, because of the dry climate, according to him, the practice of medicine is so specialized among them that each physician is a healer of one disease and no more. Although Egyptian medicine, to an extent, dealt with the supernatural, it eventually developed a practical use in the fields of anatomy, public health. Medical information in the Edwin Smith Papyrus may date to a time as early as 3000 BC, the Edwin Smith Papyrus is regarded as a copy of several earlier works and was written c.1600 BC. It is an ancient textbook on surgery almost completely devoid of magical thinking and describes in detail the examination, diagnosis, treatment. The Kahun Gynaecological Papyrus treats womens complaints, including problems with conception, thirty four cases detailing diagnosis and treatment survive, some of them fragmentarily. Dating to 1800 BCE, it is the oldest surviving text of any kind

Culture
–
Culture can be defined in numerous ways. In the words of anthropologist E. B, Tylor, it is that complex whole which includes knowledge, belief, art, morals, law, custom and any other capabilities and habits acquired by man as a member of society. The Cambridge English Dictionary states that culture is the way of life, especially the customs and beliefs. As a defining aspect of what it means to be human, culture is a concept in anthropology. The word is used in a sense as the evolved ability to categorize and represent experiences with symbols. The level of cultural sophistication has also sometimes seen to distinguish civilizations from less complex societies. Mass culture refers to the mass-produced and mass mediated forms of culture that emerged in the 20th century. When used as a count noun, a culture is the set of customs, traditions, in this sense, multiculturalism is a concept that values the peaceful coexistence and mutual respect between different cultures inhabiting the same planet. Sometimes culture is used to describe specific practices within a subgroup of a society. Samuel Pufendorf took over this metaphor in a context, meaning something similar. His use, and that of many writers after him, refers to all the ways in which human beings overcome their original barbarism, and through artifice, become fully human. To be cultural, to have a culture, is to inhabit a place sufficiently intensive to cultivate it—to be responsible for it, to respond to it, thus a contrast between culture and civilization is usually implied in these authors, even when not expressed as such. Cultural invention has come to any innovation that is new and found to be useful to a group of people and expressed in their behavior. Humanity is in a global accelerating culture change period, driven by the expansion of commerce, the mass media, and above all. Culture repositioning means the reconstruction of the concept of a society. Cultures are internally affected by both forces encouraging change and forces resisting change, Social conflict and the development of technologies can produce changes within a society by altering social dynamics and promoting new cultural models, and spurring or enabling generative action. These social shifts may accompany ideological shifts and other types of cultural change, for example, the U. S. feminist movement involved new practices that produced a shift in gender relations, altering both gender and economic structures. Environmental conditions may also enter as factors, Cultures are externally affected via contact between societies, which may also produce—or inhibit—social shifts and changes in cultural practices

Prehistory
–
Prehistory means literally before history, from the Latin word for before, præ, and Greek ιστορία. Neighbouring civilisations were the first to follow, most other civilisations reached the end of prehistory during the Iron Age. The period when a culture is written about by others, but has not developed its own writing is known as the protohistory of the culture. By definition, there are no records from human prehistory. Clear techniques for dating were not well-developed until the 19th century and this article is concerned with human prehistory as defined here above. There are separate articles for the history of the Earth. However, for the race as a whole, prehistory ends when recorded history begins with the accounts of the ancient world around the 4th millennium BC. For example, in Egypt it is accepted that prehistory ended around 3200 BC, whereas in New Guinea the end of the prehistoric era is set much more recently. The three-age system is the periodization of prehistory into three consecutive time periods, named for their respective predominant tool-making technologies, Stone Age Bronze Age Iron Age. The notion of prehistory began to surface during the Enlightenment in the work of antiquarians who used the word primitive to describe societies that existed before written records, the first use of the word prehistory in English, however, occurred in the Foreign Quarterly Review in 1836. The main source for prehistory is archaeology, but some scholars are beginning to more use of evidence from the natural and social sciences. This view has been articulated by advocates of deep history, human population geneticists and historical linguists are also providing valuable insight for these questions. Human prehistory differs from history not only in terms of its chronology, restricted to material processes, remains and artifacts rather than written records, prehistory is anonymous. Because of this, reference terms that use, such as Neanderthal or Iron Age are modern labels with definitions sometimes subject to debate. Palaeolithic means Old Stone Age, and begins with the first use of stone tools, the Paleolithic is the earliest period of the Stone Age. The early part of the Palaeolithic is called the Lower Palaeolithic, evidence of control of fire by early humans during the Lower Palaeolithic Era is uncertain and has at best limited scholarly support. The most widely accepted claim is that H. erectus or H. ergaster made fires between 790,000 and 690,000 BP in a site at Bnot Yaakov Bridge, Israel. The use of fire enabled early humans to cook food, provide warmth, Early Homo sapiens originated some 200,000 years ago, ushering in the Middle Palaeolithic

Artifact (archaeology)
–
An artifact or artefact is. something made or given shape by man, such as a tool or a work of art, esp an object of archaeological interest. In archaeology, however, the word has become a term of particular nuance and is defined as, an object recovered by archaeological endeavor, which may have a cultural interest. However, modern archaeologists take care to distinguish material culture from ethnicity, examples include stone tools, pottery vessels, metal objects such as weapons, and items of personal adornment such as buttons, jewelry and clothing. Bones that show signs of modification are also examples. Natural objects, such as fire cracked rocks from a hearth or plant material used for food, are classified by archeologists as ecofacts rather than as artifacts, natural objects that humans have moved but not changed are called manuports. Examples include seashells moved inland, or rounded pebbles placed away from the action that made them. For instance, a bone removed from a carcass is a biofact. Similarly there can be debate over early stone objects that could be either crude artifacts or naturally occurring and it can be difficult to distinguish the differences between actual man-made lithic artifacts and geofacts – naturally occurring lithics that resemble man-made tools. It is possible to authenticate artifacts by examining the general attributed to man-made tools. Artifact Collection at the Royal Military College of Canada Museum in Kingston, Ontario

Cadaver
–
A cadaver, also called corpse in medical, literary, and legal usage, or when intended for dissection, is a deceased body. Observation of the stages of decomposition can help determine how long a body has been dead. The first stage is autolysis, more known as self-digestion. However, these enzymes are released into the cells because of active processes ceasing in the cells, as a result of autolysis, liquid is created that gets between the layers of skin and makes the skin peel off. During this stage, flies start to lay eggs in the openings of the body, eyes, nostrils, mouth, ears, open wounds, hatched larvae, of blowflies, subsequently get under the skin and start to eat the body. This bloating occurs largely in the abdomen, and sometimes in the mouth and this usually happens in about the second week of decomposition. Gas accumulation and bloating will continue until the body is decomposed sufficiently for the gas to escape and it is the last and longest stage. Putrefaction is where the structures of the body break down. The digestive organs, the brain, and lungs are the first to disintegrate, under normal conditions, the organs are unidentifiable after three weeks. The muscles can be eaten by bacteria or devoured by animals, eventually, sometimes after several years, all that remains is the skeleton. In acid-rich soils, the skeleton will eventually dissolve into its base chemicals, the rate of decomposition depends on many factors including temperature and the environment. The warmer and more humid the environment, the faster the body is broken down, greek physicians Herophilus and Erasistratus were among the first on record to have dissected bodies. Andreas Vesalius, author of De humani corporis fabrica, who was able to dispel many misconceptions by dissecting human cadavers, is regarded as the father of human anatomy. The tradition of dissecting criminals was carried up into the eighteenth and nineteenth century when anatomy schools became popular in England and Scotland, at that time, a greater percentage of Christians believed in the literal raising from the dead. Because the souls of dissected bodies could not go to heaven, criminals who were executed for their crimes were used as the first cadavers. From the 16th century until 1832, and the passage of the Anatomy Act, the demand for cadavers increased when the number of criminals being executed decreased. Since corpses were in high demand, it became commonplace to steal bodies from graves in order to keep the market supplied. The methods of preserving cadavers have changed over the last 200 years, at that time, cadavers had to be used immediately because there were no adequate methods to keep the body from quickly decaying

Anthropology
–
Anthropology is the study of various aspects of humans within past and present societies. Social anthropology and cultural anthropology study the norms and values of societies, linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the development of humans. The abstract noun anthropology is first attested in reference to history and its present use first appeared in Renaissance Germany in the works of Magnus Hundt and Otto Casmann. Their New Latin anthropologia derived from the forms of the Greek words ánthrōpos and lógos. It began to be used in English, possibly via French anthropologie, various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839 and its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned and these anthropologists of the times were liberal, anti-slavery, and pro-human-rights activists. Anthropology and many other current fields are the results of the comparative methods developed in the earlier 19th century. For them, the publication of Charles Darwins On the Origin of Species was the epiphany of everything they had begun to suspect, Darwin himself arrived at his conclusions through comparison of species he had seen in agronomy and in the wild. Darwin and Wallace unveiled evolution in the late 1850s, there was an immediate rush to bring it into the social sciences. When he read Darwin he became a convert to Transformisme. His definition now became the study of the group, considered as a whole, in its details. Broca, being what today would be called a neurosurgeon, had taken an interest in the pathology of speech and he wanted to localize the difference between man and the other animals, which appeared to reside in speech. He discovered the speech center of the brain, today called Brocas area after him. The title was translated as The Anthropology of Primitive Peoples. The last two volumes were published posthumously, Waitz defined anthropology as the science of the nature of man. By nature he meant matter animated by the Divine breath, i. e. he was an animist and he stresses that the data of comparison must be empirical, gathered by experimentation

Uncontacted peoples
–
Few peoples have remained totally uncontacted by global civilization. Indigenous rights activists call for such groups to be left alone, in 2013 it was estimated that there were more than 100 uncontacted tribes around the world, mostly in the densely forested areas of South America, Central Africa, and New Guinea. Knowledge of the existence of these groups comes mostly from infrequent and sometimes violent encounters with neighboring tribes, Isolated tribes may lack immunity to common diseases, which can kill a large percentage of their people after contact. A BBC Four documentary in 2006 documented a controversial American tour operator who specializes in escorted tours to discover uncontacted people in West Papua. In 1971 the BBC made a documentary A Blank on the Map in which the first contact in over a decade was made with the Biami people of Papua New Guinea, two tribes of the Andaman Islands, in India, have sought to avoid contact with the outside world. The Sentinelese continue to actively and violently reject contact and they live on North Sentinel Island, a small and remote island which lies to the west of the southern part of South Andaman Island in the Bay of Bengal. Their language is different even from other languages on the Andamans. They are thus considered the most isolated people in the world, during Indian Census 2001, the joint expedition was conducted during 23–24 February 2001 in two batches. The first batch could identify 31 Sentinelese, the second batch could count altogether 39 Sentinelese consisting of male and females adults, children and infants. Helicopter surveys after the 2004 Indian Ocean tsunami indicate the Sentinelese survived, the local Andaman and Nicobar Administration has adopted an eyes-on and hands-off policy to ensure that no poachers enter into the island. A protocol of Circumnavigation of the North Sentinel Island has been made, another Andamanese tribe, the Jarawas, live on the main islands. They rejected all contact, but following the completion of a road traversing their territory in 1997. They are thought to number 300 people, the Bangru people, living in the same general location, were not recognized until later. The Rục people, when first encountered by North Vietnamese soldiers during the Vietnam War, were hunting-gathering tribes, since then, the government has made many attempts to relocate them. In 1984, a group of Pintupi people who were living a traditional hunter-gatherer life were tracked down in the Gibson Desert in Western Australia, for the first time, they encountered people from the Australian society. They are believed to have been the last uncontacted tribe in Australia, large areas of New Guinea are unexplored by scientists and anthropologists due to extensive forestation and mountainous terrain. Known indigenous tribes in Papua New Guinea have very little contact with local authorities aside from the authorities knowing who they are, many remain pre-literate, etc. and at the national or international level, the names of tribes and information about them is extremely hard to obtain. The Indonesian provinces of Papua and West Papua on the island of New Guinea are home to an estimated 44 uncontacted tribal groups, Isolated tribes have been reported also in the eastern Indonesian islands

Indigenous peoples
–
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

Latte stone
–
A latte stone, or simply latte, is a pillar capped by a hemispherical stone capital with the flat side facing up. Used as building supports by the ancient Chamorro people, they are throughout most of the Mariana Islands. In modern times, the stone is seen as a sign of Chamorro identity and is used in many different contexts. Latte stones have been made of limestone, basalt, or sandstone, typical pillars range in height from 60 centimeters to three meters, and generally narrow towards the top. The pillar was normally quarried and then transported to the construction site, for small to medium-sized lattes, the capstone was a large hemispherical coral head that was gathered from a reef. The massive capstones found in Rota were instead quarried, like the pillars, in Oceania the latte stone is unique to the Marianas, though megaliths of differing construction and purpose are common to Oceanic cultures. Similarities between the stone and the wood posts made by the Ifugao sub-group of the Igorot in the Philippines. The rounded capstones help prevent rats from climbing up the pillar, Latte stones varied greatly in size. The smallest were several feet tall, the largest latte still standing is 16 feet tall, located in Tinian. In Rota, quarried latte would have stood 25 feet high if erected, the largest shaft found here weighs 34 tons while the largest cap weighs 22 tons. The history of the pre-contact Marianas is usually divided into three periods, Pre-Latte, Transitional Pre-Latte, and Latte, undisturbed stones are found usually arranged in parallel pairs of between eight and fourteen lattes framing a rectangular space. The more pairs in the structure, the taller the latte stones, one twenty latte arrangement was found in the current location of the military Ordnance Annex on southern Guam. However, the lack of definitive, consistent evidence means that all theories are disputed, archaeologists who have worked in the Marianas since the end of World War II have noted a distinct difference between latte stones located along the coast, as opposed to those located inland. Coastal latte tend to be placed in sand containing extensive relics of habitation, including shards of pottery, fish and animal bones, human burials were placed within sand containing these archaeological remnants, either within or near sets of lattes. In contrast, the soil in which inland lattes stones are placed rarely has an archaeological stratum or associated burial, the implication is that mainland latte sites were temporarily occupied, and perhaps of a change in burial practice in the later Latte Period. In modern times, latte stones are a symbol of Chamorro identity and are found in a variety of government, business. Concrete lattes are sometimes incorporated into new buildings, while residents of the Marianas will sometimes incorporate actual latte stones into the landscaping around their homes, history of Guam Moai Nan Madol Staddle stones Media related to Latte stones at Wikimedia Commons

Rosemary
–
It is a member of the mint family Lamiaceae, which includes many other herbs. The name rosemary derives from the Latin for dew and sea, the plant is also sometimes called anthos, from the ancient Greek word ἄνθος, meaning flower. Rosemary has a root system. Rosmarinus officinalis is one of 2–4 species in the genus Rosmarinus, the other species most often recognized is the closely related, Rosmarinus eriocalyx, of the Maghreb of Africa and Iberia. The genus was named by the 18th-century naturalist and founding taxonomist Carl Linnaeus, Rosemary is an aromatic evergreen shrub with leaves similar to hemlock needles. It is native to the Mediterranean and Asia, but is hardy in cool climates. It can withstand droughts, surviving a severe lack of water for lengthy periods, forms range from upright to trailing, the upright forms can reach 1.5 m tall, rarely 2 m. The leaves are evergreen, 2–4 cm long and 2–5 mm broad, green above, the plant flowers in spring and summer in temperate climates, but the plants can be in constant bloom in warm climates, flowers are white, pink, purple or deep blue. Rosemary also has a tendency to flower outside its normal flowering season, it has known to flower as late as early December. According to legend, it was draped around the Greek goddess Aphrodite when she rose from the sea, the Virgin Mary is said to have spread her blue cloak over a white-blossomed rosemary bush when she was resting, and the flowers turned blue. The shrub then became known as the Rose of Mary, Rosemary is used as a decorative plant in gardens where it may have pest control effects. The leaves are used to various foods, such as stuffings. Since it is attractive and drought-tolerant, rosemary is used as a plant in gardens and for xeriscape landscaping. It is considered easy to grow and pest-resistant, Rosemary can grow quite large and retain attractiveness for many years, can be pruned into formal shapes and low hedges, and has been used for topiary. It is easily grown in pots, the groundcover cultivars spread widely, with a dense and durable texture. Rosemary grows on friable loam soil with good drainage in an open and it will not withstand waterlogging and some varieties are susceptible to frost. It grows best in neutral to alkaline conditions with average fertility and it can be propagated from an existing plant by clipping a shoot 10–15 cm long, stripping a few leaves from the bottom, and planting it directly into soil. Numerous cultivars have been selected for garden use, fresh or dried leaves are used in traditional Mediterranean cuisine

Herb
–
In general use, herbs are any plants used for food, flavoring, medicine, or fragrances for their savory or aromatic properties. Culinary use typically distinguishes herbs from spices, Herbs refers to the leafy green or flowering parts of a plant, while spices are produced from other parts of the plant, including seeds, berries, bark, roots and fruits. In botanical English, the herb is also used as a synonym of herbaceous plant. Herbs have a variety of uses including culinary, medicinal, and in some cases, general usage of the term herb differs between culinary herbs and medicinal herbs. In medicinal or spiritual use any of the parts of the plant might be considered herbs, including leaves, roots, flowers, seeds, root bark, inner bark, resin and pericarp. The word herb is pronounced /ˈhɜːrb/ in the UK, but /ˈɜːrb/ is common among North American speakers, as far back as 5000 BCE, Sumerians used herbs in medicine. Ancient Egyptians used fennel, coriander and thyme around 1555 BCE, in ancient Greece, in 162 CE, a physician by the name of Galen was known for concocting complicated herbal remedies that contained up to 100 ingredients. Culinary herbs are distinguished from vegetables in that, like spices, they are used in small amounts, Herbs can be perennials such as thyme or lavender, biennials such as parsley, or annuals like basil. Perennial herbs can be such as rosemary, Rosmarinus officinalis, or trees such as bay laurel, Laurus nobilis – this contrasts with botanical herbs. Some plants are used as herbs and spices, such as dill weed and dill seed or coriander leaves and seeds. Also, there are some such as those in the mint family that are used for both culinary and medicinal purposes. Some plants contain phytochemicals that have effects on the body, there may be some effects when consumed in the small levels that typify culinary spicing, and some herbs are toxic in larger quantities. For instance, some types of herbal extract, such as the extract of St. Johns-wort or of kava can be used for purposes to relieve depression. However, large amounts of these herbs may lead to toxic overload that may involve complications, some of a serious nature, Herbs have long been used as the basis of traditional Chinese herbal medicine, with usage dating as far back as the first century CE and far before. In India, the Ayurveda medicinal system is based on herbs, medicinal use of herbs in Western cultures has its roots in the Hippocratic elemental healing system, based on a quaternary elemental healing metaphor. Famous herbalist of the Western tradition include Avicenna, Galen, Paracelsus, Culpepper, the indigenous peoples of Australia developed herbal medicine based on plants that were readily available to them. The isolation of the people meant the remedies developed were for far less serious diseases. Herbs such as mint, wattle and eucalyptus were used for coughs, diarrhea, fever

Natural source
–
A natural product is a chemical compound or substance produced by a living organism—that is, found in nature. In the broadest sense, natural products include any substance produced by life, natural products can also be prepared by chemical synthesis and have played a central role in the development of the field of organic chemistry by providing challenging synthetic targets. The term natural product has also extended for commercial purposes to refer to cosmetics, dietary supplements. Within the field of chemistry, the definition is often further restricted to secondary metabolites. Secondary metabolites are not essential for survival, but nevertheless provide organisms that produce them an evolutionary advantage, many secondary metabolites are cytotoxic and have been selected and optimized through evolution for use as chemical warfare agents against prey, predators, and competing organisms. Natural products sometimes have pharmacological or biological activity that can be of benefit in treating diseases. As such, natural products are the active components not only of most traditional medicines, in fact, natural products are the inspiration for approximately one half of U. S. Food and Drug Administration-approved drugs. The broadest definition of natural product is anything that is produced by life, and includes the likes of biotic materials, bio-based materials, bodily fluids, a more restrictive definition of a natural product is an organic compound that is synthesized by a living organism. The remainder of this article restricts itself to this more narrow definition, natural products may be classified according to their biological function, biosynthetic pathway, or source as described below. Following Albrecht Kossels original proposal in 1891, natural products are divided into two major classes, the primary and secondary metabolites. Primary metabolites have a function that is essential to the survival of the organism that produces them. Secondary metabolites in contrast have a function that mainly affects other organisms. Secondary metabolites are not essential to survival but do increase the competitiveness of the organism within its environment, because of their ability to modulate biochemical and signal transduction pathways, some secondary metabolites have useful medicinal properties. Natural products especially within the field of chemistry are often defined as primary and secondary metabolites. A more restrictive definition limiting natural products to secondary metabolites is commonly used within the fields of medicinal chemistry, primary metabolites as defined by Kossel are components of basic metabolic pathways that are required for life. They are associated with cellular functions such as nutrient assimilation, energy production. They have a species distribution that span many phyla and frequently more than one kingdom. Primary metabolites include carbohydrates, lipids, amino acids, and nucleic acids which are the building blocks of life

Nomad
–
A nomad is a member of a community of people who live in different locations, moving from one place to another. Among the various ways nomads relate to their environment, one can distinguish the hunter-gatherer, as of 1995, there were an estimated 30–40 million nomads in the world. Nomadic hunting and gathering, following seasonally available wild plants and game, is by far the oldest human subsistence method, pastoralists raise herds, driving them, or moving with them, in patterns that normally avoid depleting pastures beyond their ability to recover. Nomadism is also a lifestyle adapted to regions such as steppe, tundra, or ice and sand. For example, many groups in the tundra are reindeer herders and are semi-nomadic and these nomads sometimes adapt the use of high technology such as solar photovoltaics to reduce their dependence on diesel fuel. These groups are known as peripatetic nomads, a nomad is a person with no settled home, moving from place to place as a way of obtaining food, finding pasture for livestock, or otherwise making a living. The word Nomad comes from a Greek word that one who wanders for pasture. Most nomadic groups follow an annual or seasonal pattern of movements and settlements. Nomadic peoples traditionally travel by animal or canoe or on foot, today, some nomads travel by motor vehicle. Most nomads live in tents or other portable shelters, Nomads keep moving for different reasons. Nomadic foragers move in search of game, edible plants, the Australian Aborigines, Negritos of Southeast Asia, and San of Africa, for example, traditionally move from camp to camp to hunt and to gather wild plants. Some tribes of the Americas followed this way of life, Pastoral nomads make their living raising livestock, such as camels, cattle, goats, horses, sheep, or yaks. These nomads travel to find more camels, goats, and sheep through the deserts of Arabia, the Fulani and their cattle travel through the grasslands of Niger in western Africa. Some nomadic peoples, especially herders, may move to raid settled communities or avoid enemies. Nomadic craftworkers and merchants travel to find and serve customers and they include the Lohar blacksmiths of India, the Romani traders, and the Irish Travellers. Most nomads travel in groups of families called bands or tribes and these groups are based on kinship and marriage ties or on formal agreements of cooperation. A council of adult males makes most of the decisions, though some tribes have chiefs, in the case of Mongolian nomads, a family moves twice a year. These two movements would generally occur during the summer and winter, the winter location is usually located near mountains in a valley and most families already have their fixed winter locations

Fomitopsis betulina
–
The brackets burst out from the bark of the tree, and these fruiting bodies can last for more than a year. Technically, it is a mushroom, with a strong, pleasant mushroomy odor. The velvety cut surface of the body was traditionally used as a strop for finishing the finest of edges on razors. It is also said to have medicinal properties, the fruiting bodies are pale, with a smooth greyish-brown top surface, with the underside a creamy white and with hundreds of pores that contain the spores. The fruiting body has a texture, becoming corky with age. Wood decayed by the fungus, and cultures of its mycelium, there are at least 33 different mating-type factors within the British population of this fungus. These factors are all variants or alleles of a gene, as opposed to the tetrapolar mating system of some other basidiomycete species. The geographic distribution of Piptoporus betulinus appears to be restricted to the Northern Hemisphere, there is some doubt about the ability of isolates from the European continent, North America and the British Isles to interbreed. It is a parasite on weakened birches, and will cause brown rot and eventually death. Fire, drought and suppression by other trees are common causes of such stress and these fungal individuals can sometimes be seen if a slice of brown-rotted birch wood is incubated in a plastic bag for several days. This allows the mycelium of the fungus to grow out of the surface of the wood. If more than one individual dikaryon is present, lines of intraspecific antagonism form as the two individual mycelia interact and repel each other, the fungus can harbor a large number of species of insects that depend on it for food and as breeding sites. In a large-scale study of over 2600 fruit bodies collected in eastern Canada,257 species of arthropods, the fungus is eaten by the caterpillars of the fungus moth Nemaxera betulinella. Piptoporus betulinus has anti-inflammatory compounds and antibacterial properties, polyporenic acid found in the fruit body of the fungus, is poisonous to the parasitic whipworm Trichuris trichura. The fungus was carried by Ötzi the Iceman – the 5, 000-year-old mummy found in Tyrol

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

Geophagia
–
Geophagia is the practice of eating earth or soil-like substrates such as clay or chalk. It occurs in animals where it may be a normal or abnormal behaviour. Human geophagia may be related to pica, a disorder in the Diagnostic. Here, a white clay was found alongside the bones of Homo habilis. Geophagia is nearly universal around the world in tribal and traditional rural societies, in the ancient world, several writers noted the use of geophagia. Pliny is said to have noted the use of soil on Lemnos, an island of Greece, the textbook of Hippocrates mentions geophagia, and the famous medical textbook called De Medicina edited by A Cornelius Celsus seems to link anaemia to geophagia. Geophagia was common among slaves who were nicknamed clay-eaters because they had known to consume clay, as well as spices, ash, chalk, grass, plaster, paint. The literature also states, Many men believed that eating clay increased sexual prowess, geophagia among southerners may have been caused by the high prevalence of hookworm disease, in which the desire to consume soil is a symptom. In Africa, kaolin, sometimes known as kalaba, calaba, kaolin for human consumption is sold at most markets in Cameroon and is often flavoured with spices such as black pepper and cardamom. Consumption is greater among women, especially during pregnancy, in Haiti, people afflicted by poverty are known to eat biscuits made from soil, salt, and vegetable shortening. These biscuits hold minimal nutritional value, but manages to keep the poor alive, however, their long-term consumption is reported to cause stomach pains, and could be a source of malnutrition, and is not recommended by doctors. In the United States, cooked, baked, and processed dirt and clay are sold in food stores. In the rural areas of Mississippi and other states, the consumption of clay-rich dirt has been a common custom and has been practiced by poor whites. However, geophagia has become prevalent as rural Americans assimilate into urban culture. Bentonite clay is available worldwide as an aid, kaolin is also widely used as a digestive aid. Attapulgite, another type of clay, is an ingredient in many anti-diarrheal medicines. Geophagia is widespread in the animal kingdom, galen, the Greek philosopher and physician, was the first to record the use of clay by sick or injured animals in the second century AD. This type of geophagia has been documented in species of mammals, birds, reptiles, butterflies and isopods

Medicinal clay
–
The use of medicinal clay in folk medicine goes back to prehistoric times. Indigenous peoples around the world still use clay widely, which is related to geophagy, the first recorded use of medicinal clay goes back to ancient Mesopotamia. A wide variety of clays are used for medicinal purposes—primarily for external applications, among the clays most commonly used are kaolin and the smectite clays such as bentonite, montmorillonite, and Fullers earth. There are considerable problems with the nomenclature of various clays. No clay deposit is exactly the same and, typically, mineral clays are mixed in various proportions, the overwhelming majority of clay mined commercially is for industrial uses, such as construction and oil drilling. Thus, the classification and chemical composition of these clays are somewhat secondary to their intended use. Bentonite clay, montmorillonite clay, and Fullers earth are similar, sodium bentonite/calcium bentonite are the most commonly used medicinal clays today, although there is no precise definition of what this term means. In fact, typically, bentonite refers to a spectrum of clays with a wide array of properties. In alternative medicine, often this is used as more or less a catch-all term for medicinal clays, another such term is montmorillonite, which is often interchangeable with bentonite. Bentonite is included in the United States Pharmacopeia, and the USP-grade bentonite is used in various pharmaceutical. It is not entirely clear where the source of USP-grade bentonite is located, most of the nomenclature currently used is discussed in a 2005 World Health Organization report BENTONITE, KAOLIN, AND. SELECTED CLAY MINERALS, as well as a section of the USGS website Minerals Information. This type of geophagy has been documented in species of mammals, birds, reptiles, butterflies and isopods. In particular, in Peru, Amazonian rainforest parrots of some 21 species gather at sites on cliff faces where bare soil is exposed. The soil they eat is specific, since they focus on a narrow band of exposed soil. What they eat is mostly clay that is less than 0.2 millimetre in particle diameter, some scholars believe that prehistoric ancestors such as Homo erectus and Homo neanderthalensis used ochres to cure wounds as well as paint caves. Ochres are a mixture of clay and iron hydroxides, the oldest evidence of geophagy practiced by humans comes from the prehistoric site at Kalambo Falls on the border between Zambia and Tanzania. Here, a white clay was found alongside the bones of Homo habilis

Surgical operation
–
An act of performing surgery may be called a surgical procedure, operation, or simply surgery. In this context, the verb means to perform surgery. The adjective surgical means pertaining to surgery, e. g. surgical instruments or surgical nurse, the patient or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and an assistant is a person who practices surgical assistance. A surgical team is made up of surgeon, surgeons assistant, anesthesia provider, circulating nurse, Surgery usually spans minutes to hours, but it is typically not an ongoing or periodic type of treatment. The term surgery can also refer to the place where surgery is performed, or simply the office of a physician, dentist, Surgery is a technology consisting of a physical intervention on tissues. As a general rule, a procedure is considered surgical when it involves cutting of a patients tissues or closure of a previously sustained wound, surgical procedures are commonly categorized by urgency, type of procedure, body system involved, degree of invasiveness, and special instrumentation. Based on timing, Elective surgery is done to correct a condition, and is carried out at the patients request, subject to the surgeons. A semi-elective surgery is one that must be done to avoid permanent disability or death, emergency surgery is surgery which must be done promptly to save life, limb, or functional capacity. Based on purpose, Exploratory surgery is performed to aid or confirm a diagnosis, therapeutic surgery treats a previously diagnosed condition. Cosmetic surgery is done to improve the appearance of an otherwise normal structure. By type of procedure, Amputation involves cutting off a part, usually a limb or digit. Resection is the removal of all or part of an organ or part of the body. Replantation involves reattaching a severed body part, reconstructive surgery involves reconstruction of an injured, mutilated, or deformed part of the body. Excision is the cutting out or removal of an organ, tissue, transplant surgery is the replacement of an organ or body part by insertion of another from different human into the patient. Removing an organ or body part from a human or animal for use in transplant is also a type of surgery. By body part, When surgery is performed on one system or structure. Examples include cardiac surgery, gastrointestinal surgery, and orthopedic surgery, by contrast, an open surgical procedure such as a laparotomy requires a large incision to access the area of interest

Peru
–
Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peruvian territory was home to ancient cultures spanning from the Norte Chico civilization in Caral, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty with its capital in Lima, ideas of political autonomy later spread throughout Spanish America and Peru gained its independence, which was formally proclaimed in 1821. After the battle of Ayacucho, three years after proclamation, Peru ensured its independence, subsequently, the country has undergone changes in government from oligarchic to democratic systems. Peru has gone through periods of political unrest and internal conflict as well as periods of stability, Peru is a representative democratic republic divided into 25 regions. It is a country with a high Human Development Index score. Its main economic activities include mining, manufacturing, agriculture and fishing, the Peruvian population, estimated at 31.2 million in 2015, is multiethnic, including Amerindians, Europeans, Africans and Asians. The main spoken language is Spanish, although a significant number of Peruvians speak Quechua or other native languages and this mixture of cultural traditions has resulted in a wide diversity of expressions in fields such as art, cuisine, literature, and music. The name of the country may be derived from Birú, the name of a ruler who lived near the Bay of San Miguel, Panama. When his possessions were visited by Spanish explorers in 1522, they were the southernmost part of the New World yet known to Europeans, thus, when Francisco Pizarro explored the regions farther south, they came to be designated Birú or Perú. An alternative history is provided by the contemporary writer Inca Garcilasco de la Vega, son of an Inca princess, the Spanish Crown gave the name legal status with the 1529 Capitulación de Toledo, which designated the newly encountered Inca Empire as the province of Peru. Under Spanish rule, the country adopted the denomination Viceroyalty of Peru, the earliest evidences of human presence in Peruvian territory have been dated to approximately 9,000 BC. Andean societies were based on agriculture, using such as irrigation and terracing, camelid husbandry. Organization relied on reciprocity and redistribution because these societies had no notion of market or money, the oldest known complex society in Peru, the Norte Chico civilization, flourished along the coast of the Pacific Ocean between 3,000 and 1,800 BC. These early developments were followed by archaeological cultures that developed mostly around the coastal, the Cupisnique culture which flourished from around 1000 to 200 BC along what is now Perus Pacific Coast was an example of early pre-Incan culture. The Chavín culture that developed from 1500 to 300 BC was probably more of a religious than a political phenomenon, on the coast, these included the civilizations of the Paracas, Nazca, Wari, and the more outstanding Chimu and Mochica. Their capital was at Chan Chan outside of modern-day Trujillo, in the 15th century, the Incas emerged as a powerful state which, in the span of a century, formed the largest empire in pre-Columbian America with their capital in Cusco

Fracture
–
A fracture is the separation of an object or material into two or more pieces under the action of stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid, fracture strength or breaking strength is the stress when a specimen fails or fractures. The word fracture is often applied to bones of living creatures, or to crystalline materials, sometimes, individual crystals fracture without the structure actually separating into two or more pieces. Depending on the substance, a fracture reduces strength or inhibits transmission of waves, a detailed understanding of how fracture occurs in materials may be assisted by the study of fracture mechanics. Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture and this is usually determined for a given specimen by a tensile test, which charts the stress-strain curve. The final recorded point is the fracture strength, ductile materials have a fracture strength lower than the ultimate tensile strength, whereas in brittle materials the fracture strength is equivalent to the UTS. If a ductile material reaches its ultimate strength in a load-controlled situation, it will continue to deform, with no additional load application. However, if the loading is displacement-controlled, the deformation of the material may relieve the load, in brittle fracture, no apparent plastic deformation takes place before fracture. In brittle crystalline materials, fracture can occur by cleavage as the result of tensile stress acting normal to crystallographic planes with low bonding. In amorphous solids, by contrast, the lack of a crystalline structure results in a conchoidal fracture, the sinking of RMS Titanic in 1912 from an iceberg collision is widely reported to have been due to brittle fracture of the hulls steel plates. Putting these two together, we get σ f r a c t u r e = E γ ρ4 a r o. Looking closely, we can see that sharp cracks and large defects both lower the strength of the material. Recently, scientists have discovered supersonic fracture, the phenomenon of crack propagation faster than the speed of sound in a material and this phenomenon was recently also verified by experiment of fracture in rubber-like materials. Brittle fracture may be avoided by limiting pressure and temperature within limits, each system has a brittle fracture prevention limit curve defined by the weakest components at given temperatures and pressures allowing for the largest undetected preexisting flaw in each component. In ductile fracture, extensive plastic deformation takes place before fracture, the terms rupture or ductile rupture describe the ultimate failure of ductile materials loaded in tension. Rather than cracking, the material pulls apart, generally leaving a rough surface, in this case there is slow propagation and an absorption of a large amount energy before fracture. The ductility of a material is referred to as toughness. Many ductile metals, especially materials with high purity, can sustain very large deformation of 50–100% or more strain before fracture under favorable loading condition, the strain at which the fracture happens is controlled by the purity of the materials

Americas
–
The Americas, also collectively called America, encompass the totality of the continents of North America and South America. Together they make up most of the land in Earths western hemisphere, along with their associated islands, they cover 8% of Earths total surface area and 28. 4% of its land area. The topography is dominated by the American Cordillera, a chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by river basins, such as the Amazon, St. Lawrence River / Great Lakes basin, Mississippi. Humans first settled the Americas from Asia between 42,000 and 17,000 years ago, a second migration of Na-Dene speakers followed later from Asia. The subsequent migration of the Inuit into the neoarctic around 3500 BCE completed what is regarded as the settlement by the indigenous peoples of the Americas. The first known European settlement in the Americas was by the Norse explorer Leif Ericson, however, the colonization never became permanent and was later abandoned. The voyages of Christopher Columbus from 1492 to 1502 resulted in permanent contact with European powers, diseases introduced from Europe and Africa devastated the indigenous peoples, and the European powers colonized the Americas. Mass emigration from Europe, including numbers of indentured servants. Decolonization of the Americas began with the American Revolution in 1776, the population is over 1 billion, with over 65% of them living in one of the three most populous countries. As of the beginning of the 2010s, the most populous urban agglomerations are Mexico City, New York, Sao Paulo, Los Angeles, Buenos Aires and Rio de Janeiro, all of them megacities. The name America was first recorded in 1507 in the Cosmographiae Introductio, apparently written by Matthias Ringmann and it first applied to both North and South America by Gerardus Mercator in 1538. Amerigen means land of Amerigo and derives from Amerigo and gen, America accorded with the feminine names of Asia, Africa, and Europa. When conceived as a continent, the form is generally the continent of America in the singular. However, without a context, singular America in English commonly refers to the United States of America. In some countries of the world, America is considered a continent encompassing the North America and South America subcontinents, the first inhabitants migrated into the Americas from Asia. Habitation sites are known in Alaska and the Yukon from at least 20,000 years ago, beyond that, the specifics of the Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are subject to ongoing research and discussion. Widespread habitation of the Americas occurred during the glacial maximum

Yup'ik
–
They are also known as Cupik by the Chevak Cupik dialect-speaking Eskimos of Chevak and Cupig for the Nunivak Cupig dialect-speaking Eskimo of Nunivak Island. Both Chevak Cupik and Nunivak Cupig Eskimos are also known as Cupik, the Yupik, Cupik, and Cupig speakers can converse without difficulty, and the regional population is often described using the larger term of Yupik. The Yupiit speak the Yupik language, of a total population of about 21,000 people, about 10,000 speak the language. The Yupik Eskimo combine a contemporary and a subsistence lifestyle in a blend unique to the Southwest Alaska. Today, the Yupik generally work and live in style but still hunt and fish in traditional subsistence ways. Most Yupik people still speak the language and bilingual education has been in force since the 1970s. The Yupiit are the most numerous of the various Alaska Native groups and speak the Central Alaskan Yupik language, a member of the Eskimo-Aleut family of languages. As of the 2000 U. S. Census, the Yupiit population in the United States numbered over 24,000, the vast majority of these live in the seventy or so communities in the traditional Yupik territory of western and southwestern Alaska. As of the 2010 U. S. Census, the Yupik at 34,000 people is the largest Alaska Native tribal grouping, either alone or in combination, the Yupik had the greatest number of people who identified with one tribal grouping and no other race. In that census, nearly half of American Indians and Alaska Natives identified as being of mixed race, the traditional Yupik Eskimo village of Toksook Bay is located on Nelson Island,6.5 miles southeast of Tununak, in the Yukon- Kuskokwim Delta. Families from Tununak and Newtok joined them, and the settlement grew, the city was incorporated in 1972. As of 2011, the Alaska Department of Labor estimated its population at 598, the federally recognized Nunakauyarmiut Tribe is located here. They use commercial fishing and subsistence activities to supplement income and provide food sources. Herring roe, salmon and halibut are favorite harvests, originally the form Yupik was used in the northern area while the form Yupiaq was used in the southern area. The form Yup’ik is now used as a common term, Yupik comes from the Yupik word yuk meaning person plus the postbase -pik or -piaq meaning real or genuine, thus, Yupik literally means real people. The ethnographic literature sometimes refers to the Yupik people or their language as Yuk or Yuit, in the Hooper Bay-Chevak and Nunivak dialects of Yupik, both the language and the people are given the name Cupik. The use of an apostrophe in the name Yupik, compared to Siberian Yupik, the apostrophe represents gemination of the p sound. Migrating east, they reached the Bering Sea area about 10,000 years ago and this causeway became exposed between 20,000 and 8,000 years ago during periods of glaciation. E

Shamanism
–
The word shaman probably originates from the Tungusic Evenki language of North Asia. The term was introduced to the west after Russian forces conquered the shamanistic Khanate of Kazan in 1552, Mircea Eliade writes, A first definition of this complex phenomenon, and perhaps the least hazardous, will be, shamanism = technique of religious ecstasy. Shamanism encompasses the premise that shamans are intermediaries or messengers between the world and the spirit worlds. Shamans are said to treat ailments/illness by mending the soul, alleviating traumas affecting the soul/spirit restores the physical body of the individual to balance and wholeness. The shaman also enters supernatural realms or dimensions to obtain solutions to problems afflicting the community, Shamans may visit other worlds/dimensions to bring guidance to misguided souls and to ameliorate illnesses of the human soul caused by foreign elements. The shaman operates primarily within the world, which in turn affects the human world. The restoration of balance results in the elimination of the ailment, hundreds of books and academic papers on the subject have been produced, with a peer-reviewed academic journal being devoted to the study of shamanism. The word shaman probably originates from the Evenki word šamán, most likely from the dialect spoken by the Sym Evenki peoples. The Tungusic term was adopted by Russians interacting with the indigenous peoples in Siberia. It is found in the memoirs of the exiled Russian churchman Avvakum, adam Brand, a merchant from Lübeck, published in 1698 his account of a Russian embassy to China, a translation of his book, published the same year, introduced the word shaman to English speakers. The etymology of the Evenki word is sometimes connected to a Tungus root ša- to know, other scholars assert that the word comes directly from the Manchu language, and as such would be the only commonly used English word that is a loan from this language. This proposal has been thoroughly critiqued since 1917, ethnolinguist Juha Janhunen regards it as an anachronism and an impossibility that is nothing more than a far-fetched etymology. Ethnolinguists did not develop as a discipline nor achieve contact with these communities until the late 19th century, there is no single agreed-upon definition for the word shamanism among anthropologists. The English historian Ronald Hutton noted that by the dawn of the 21st century, the first of these uses the term to refer to anybody who contacts a spirit world while in an altered state of consciousness. The second definition limits the term to refer to those who contact a spirit world while in a state of consciousness at the behest of others. Problematically, scholars advocating the third view have failed to agree on what the defining technique should be, the fourth definition identified by Hutton uses shamanism to refer to the indigenous religions of Siberia and neighboring parts of Asia. According to the Golomt Center for Shamanic Studies, a Mongolian organisation of shamans, Shamans are normally called by dreams or signs which require lengthy training. However, shamanic powers may be inherited, turner and colleagues mention a phenomenon called shamanistic initiatory crisis, a rite of passage for shamans-to-be, commonly involving physical illness and/or psychological crisis

Medicine man
–
A medicine man or medicine woman is a traditional healer and spiritual leader who serves a community of Indigenous people. Individual cultures have their own names, in their respective Indigenous languages, for the spiritual healers, in the ceremonial context of Indigenous North American communities, medicine usually refers to spiritual healing. Medicine men/women should not be confused with those who employ Native American ethnobotany, Native Americans tend to be quite reluctant to discuss issues about medicine or medicine people with non-Indians. In some cultures, the people not even discuss these matters with Indians from other tribes. In most tribes, medicine elders are prohibited from advertising or introducing themselves as such, as Nuttall writes, An inquiry to a Native person about religious beliefs or ceremonies is often viewed with suspicion. The term medicine man/woman, like the term shaman, has been criticized by Native Americans, as well as specialists in the fields of religion. The term medicine man/woman has also frequently used by Europeans to refer to African traditional healers. Cherokee Medicine People are considered the chosen ones within their tribe, the knowledge has been passed down for thousands of years. The Cherokee tribe is one of the first tribes to form a language to record their knowledge of formulas. Some of the information in these ledgers are in written code or backwards to prevent other people trying to use the ledger for their own purposes. A Cherokee Medicine person is not considered a doctor because they are known to have powers that could heal. The Medicine people kept their tools that used to heal other tribal members in a medicine bundle. When a Medicine Person treated their patients it was completely up to the person who was being treated if they did not want the medicine in case they had any opposed beliefs. Another way Medicine people would treat their patients was by using sweat lodges, in 1978, the American Indian Religious Freedom Act was passed, which allowed Medicine People to begin practicing again. Since practicing medicine was banned decades ago it completely faded, which is the reason why only a handful still practice this today, training a Cherokee Medicine Person takes years due to the vast amount of knowledge needed to practice. They learn secrets and formulas that they record in ledgers, when a medicine person learns new secrets and formulas it is important that they are not interrupted while recording their knowledge. It is also important that if one is not trained to use the knowledge they should not try to practice it without proper training. Another part of training is going into the mountains where they dance, sing, on the seventh day the Medicine People dance in a circle at the darkest hour to sacred songs while the drums get louder

Magic (paranormal)
–
Magic or sorcery is the use of rituals, symbols, actions, gestures, and language with the aim of exploiting supernatural forces. The term magic has a variety of meanings, and there is no agreed upon definition of what it is or how it can be used. Religious scholars have defined magic in many different ways, one approach, associated with the anthropologists Edward Tylor and James G. Frazer, has magic and science be opposites. Many scholars of religion have rejected the utility of the term magic, the term magic comes from the Old Persian magu, a word that applied to a form of religious functionary about which little is known. This meaning of the term was adopted by Latin in the first century BCE. The concept was incorporated into Christian theology during the first century CE. This concept was pervasive throughout the Middle Ages, although in the modern period Italian humanists reinterpreted the term in a positive sense to establish the idea of natural magic. Both negative and positive understandings of the term were retained in Western culture over the following centuries, throughout Western history, there have been examples of individuals claiming to be practitioners of magic and referring to themselves as magicians. This trend has proliferated in the period, with a growing number of magicians appearing within the esoteric milieu. Scholars of religion have failed to agree on a definition of magic is. The subject has one of intense dispute, with some scholars criticizing the validity of the term in the first place. Even among those throughout history who have described themselves as magicians, there has been some debate among scholars as to whether to use the term magic at all. The scholar of religion Jonathan Z. Smith for example argued that it had no utility as a term that scholars should use. Religious historian Wouter Hanegraaff agreed, stating that the magic is an important object of historical research. Since the 1990s its usage among scholars has declined, within Western culture, magic has been linked to the idea of the Other. Using the term magic when discussing non-Western cultures or pre-modern forms of Western society raises problems, alternately, this term implies that all categories of magic are ethnocentric and that such Western preconceptions are an unavoidable component of scholarly research. Magic is one of the most heavily theorized concepts in the study of religion, the intellectualist approach to defining magic is associated with two prominent British anthropologists, Edward Tylor and James G. Frazer. This was an approach that viewed magic as being the theoretical opposite of science, in his 1871 book Primitive Culture, Tylor characterized magic as beliefs based on the error of mistaking ideal analogy for real analogy

Oral tradition
–
Oral tradition, or oral lore, is a form of human communication where in knowledge, art, ideas and cultural material is received, preserved and transmitted orally from one generation to another. The transmission is through speech or song and may include folktales, ballads, chants, prose or verses. In this way, it is possible for a society to transmit oral history, oral literature, oral law and other knowledge across generations without a writing system, or in parallel to a writing system. Oral tradition is information, memories and knowledge held in common by a group of people, over many generations, in a general sense, oral tradition refers to the recall and transmission of a specific, preserved textual and cultural knowledge through vocal utterance. As an academic discipline, it both to a set of objects of study and a method by which they are studied. The study of tradition is distinct from the academic discipline of oral history. Oral tradition is distinct from the study of orality defined as thought. A folklore is a type of tradition, but knowledge other than folklore has been orally transmitted. According to John Foley, oral tradition has been an ancient human tradition found in all corners of the world, according to Goody, the Vedic texts likely involved both a written and oral tradition, calling it a parallel products of a literate society. In ancient Greece, the tradition was a dominant tradition. Homers epic poetry, states Michael Gagarin, was composed, performed and transmitted orally. This is evidenced, for example, by the multiple scriptural statements by Paul admitting previously remembered tradition which he received orally. Oral traditions face the challenge of accurate transmission and verifiability of the accurate version, Oral cultures have employed various strategies that achieve this without writing. For example, a rhythmic speech filled with mnemonic devices enhances memory. A few useful mnemonic devices include alliteration, repetition, assonance, in addition, the verse is often metrically composed with an exact number of syllables or morae - such as with Greek and Latin prosody and in Chandas found in Hindu and Buddhist texts. Such strategies help facilitate transmission of information from individual to individual without a written intermediate, rudyard Kiplings The Jungle Book provides an excellent demonstration of oral governance in the Law of the Jungle. Not only does grounding rules in oral proverbs allow for transmission and understanding. These stories, traditions, and proverbs are not static, but are often altered upon each transmission barring the overall meaning remains intact, in this way, the rules that govern the people are modified by the whole and not authored by a single entity

Mehrgarh
–
Mehrgarh, sometimes anglicized as Mehergarh or Mehrgar, is a Neolithic site located near the Bolan Pass on the Kacchi Plain of Balochistan, Pakistan, to the west of the Indus River valley. The earliest settlement at Mehrgarh, in the northeast corner of the 495-acre site, was a farming village which was inhabited from circa 6500 BCE. It is one of the earliest sites with evidence of farming and herding in South Asia, archaeological material has been found in six mounds, and about 32,000 artifacts have been collected. Mehrgarh is now seen as a precursor to the Indus Valley Civilization, displaying the whole sequence from earliest settlement, jean-Francois Jarrige argues for an independent origin of Mehrgarh. But given the originality of Mehrgarh, Jarrige concludes that Mehrgarh has a local background. Gallego Romero notes that Indians who are lactose-tolerant show a genetic pattern regarding this tolerance which is characteristic of the common European mutation. According to Romero, this suggests that the most common lactose tolerance mutation made a migration out of the Middle East less than 10,000 years ago. They further note that he earliest evidence of cattle herding in south Asia comes from the Indus River Valley site of Mehrgarh and is dated to 7,000 YBP, Archaeologists divide the occupation at the site into eight periods. The Mehrgarh Period I was Neolithic and aceramic, without the use of pottery, the earliest farming in the area was developed by semi-nomadic people using plants such as wheat and barley and animals such as sheep, goats and cattle. The settlement was established with simple mud buildings and most of them had four internal subdivisions, ornaments of sea shell, limestone, turquoise, lapis lazuli and sandstone have been found, along with simple figurines of women and animals. Sea shells from far sea shore and lapis lazuli found as far away as present-day Badakshan, Afghanistan shows good contact with those areas, a single ground stone axe was discovered in a burial, and several more were obtained from the surface. These ground stone axes are the earliest to come from a context in the South Asia. Periods I, II and III are contemporaneous with another site called Kili Gul Mohammed, in April 2006, it was announced in the scientific journal Nature that the oldest evidence for the drilling of human teeth in vivo was found in Mehrgarh. According to the authors, their discoveries point to a tradition of proto-dentistry in the farming cultures of that region. Here we describe eleven drilled molar crowns from nine adults discovered in a Neolithic graveyard in Pakistan that dates from 7,500 to 9,000 years ago and these findings provide evidence for a long tradition of a type of proto-dentistry in an early farming culture. The Mehrgarh Period II and Merhgarh Period III were ceramic Neolithic, using pottery, Period II is at site MR4 and Period III is at MR2. Much evidence of manufacturing activity has been found and more advanced techniques were used, glazed faience beads were produced and terracotta figurines became more detailed. Figurines of females were decorated with paint and had diverse hairstyles, two flexed burials were found in Period II with a red ochre cover on the body

Balochistan, Pakistan
–
Balochistan, is one of the four provinces of Pakistan, located in the southwestern region of the country. Its provincial capital and largest city is Quetta and it shares borders with Punjab and the Federally Administered Tribal Areas to the northeast, Sindh to the southeast, the Arabian Sea to the south, Iran to the west, and Afghanistan to the north. The name Balochistan means the land of the Baloch in many regional languages, although largely underdeveloped, the provincial economy is dominated by natural resources, especially its natural gas fields, which supply the entire country. Gwadar Port also plays a significant role in the development of the province. Balochistan is noted for its culture and extremely dry desert climate. Baloch people practice Islam and are predominantly Sunni, similar to the rest of Pakistan, Balochistan marked the westernmost extent of the Indus Valley Civilisation. Centuries before the arrival of Islam in the 7th Century, parts of Balochistan was ruled by the Paratarajas, at certain times, the Kushans also held political sway in parts of Balochistan. With time, Baloch tribes linguistically absorbed all the people in Makran, southern Sistan. By 654, the whole of what is now Balochistan was controlled by the Rashidun Caliphate, however, this town was later conquered during the reign of Caliph Ali. Abdulrehman ibn Samrah made Zaranj his provincial capital and remained governor of these areas from 654 to 656. During the Caliphate of Ali, revolt broke out in southern Balochistans Makran region. Due to civil war in the Rashidun Caliphate, Ali was unable to deal with these areas until 660, Haris ibn Marah Abdi arrived in Makran and conquered it by force, and then moved northward to north-eastern Balochistan and reconquered Qandabil. Finally, he moved south and conquered Kalat after a fierce battle, Muslim forces later regained control of the area during the Umayyad reign. It also remained a part of the Abbasid Caliphate, ahmad Shah Durrani, founder of the Afghan Empire, also won the allegiance of that areas rulers. Most of the area would revert to local Baloch control, after Afghan rule. During the period of the British Raj, there were four Princely States in Balochistan, Makran, Kharan, Las Bela and Kalat. After the Second Afghan War was ended by the Treaty of Gandamak in May 1879, on 1 April 1883, the British took control of the Bolan Pass, south-east of Quetta, from the Khan of Kalat. In 1887, small areas of Balochistan were declared British territory

Pakistan
–
Pakistan, officially the Islamic Republic of Pakistan, is a federal parliamentary republic in South Asia on the crossroads of Central Asia and Western Asia. It is the sixth-most populous country with a population exceeding 200 million people, in terms of area, it is the 33rd-largest country in the world with an area covering 881,913 square kilometres. It is separated from Tajikistan by Afghanistans narrow Wakhan Corridor in the north, Pakistan is unique among Muslim countries in that it is the only country to have been created in the name of Islam. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and it is an ethnically and linguistically diverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic, an ethnic civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. The new constitution stipulated that all laws were to conform to the injunctions of Islam as laid down in the Quran. Pakistan has an economy with a well-integrated agriculture sector. The Pakistani economy is the 24th-largest in the world in terms of purchasing power and it is ranked among the emerging and growth-leading economies of the world, and is backed by one of the worlds largest and fastest-growing middle classes. The post-independence history of Pakistan has been characterised by periods of military rule, the country continues to face challenging problems such as illiteracy, healthcare, and corruption, but has substantially reduced poverty and terrorism and expanded per capita income. It is also a member of CERN. Pakistan is a signatory to the Kyoto Protocol, the Paris Agreement, the name Pakistan literally means land of the pure in Urdu and Persian. It is a play on the word pāk meaning pure in Persian and Pashto, the letter i was incorporated to ease pronunciation and form the linguistically correct and meaningful name. Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan, the earliest known inhabitants in the region were Soanian during the Lower Paleolithic, of whom stone tools have been found in the Soan Valley of Punjab. The Vedic Civilization, characterised by Indo-Aryan culture, laid the foundations of Hinduism, Multan was an important Hindu pilgrimage centre. The Vedic civilisation flourished in the ancient Gandhāran city of Takṣaśilā, the Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab and reached its greatest extent under Menander, prospering the Greco-Buddhist culture in the region. Taxila had one of the earliest universities and centres of education in the world. At its zenith, the Rai Dynasty of Sindh ruled this region, the Pala Dynasty was the last Buddhist empire, which, under Dharampala and Devapala, stretched across South Asia from what is now Bangladesh through Northern India to Pakistan. The Arab conqueror Muhammad bin Qasim conquered the Indus valley from Sindh to Multan in southern Punjab in 711 AD, the Pakistan governments official chronology identifies this as the time when the foundation of Pakistan was laid

Indus Valley Civilisation
–
The Indus Valley Civilisation was a Bronze Age civilisation mainly in the northwestern regions of South Asia, extending from what today is northeast Afghanistan to Pakistan and northwest India. Along with ancient Egypt and Mesopotamia it was one of three early civilisations of the Old World, and of the three, the most widespread, at its peak, the Indus Civilisation may have had a population of over five million. Inhabitants of the ancient Indus river valley developed new techniques in handicraft, the Indus cities are noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, and clusters of large non-residential buildings. The discovery of Harappa, and soon afterwards, Mohenjo-Daro, was the culmination of work beginning in 1861 with the founding of the Archaeological Survey of India in the British Raj, excavation of Harappan sites has been ongoing since 1920, with important breakthroughs occurring as recently as 1999. This Harappan civilisation is called the Mature Harappan culture to distinguish it from the cultures immediately preceding and following it. The early Harappan cultures were preceded by local Neolithic agricultural villages, as of 1999, over 1,056 cities and settlements had been found, of which 96 have been excavated, mainly in the general region of the Indus and Ghaggar-Hakra Rivers and their tributaries. Among the settlements were the urban centres of Harappa, Mohenjo-daro, Dholavira, Ganeriwala in Cholistan. The Harappan language is not directly attested and its affiliation is uncertain since the Indus script is still undeciphered, a relationship with the Dravidian or Elamo-Dravidian language family is favoured by a section of scholars. Recently, Indus sites have been discovered in Pakistans northwestern Frontier Province as well, other IVC colonies can be found in Afghanistan while smaller isolated colonies can be found as far away as Turkmenistan and in Maharashtra. The largest number of colonies are in the Punjab, Sindh, Rajasthan, Haryana, Indus Valley sites have been found most often on rivers, but also on the ancient seacoast, for example, Balakot, and on islands, for example, Dholavira. There is evidence of dry river beds overlapping with the Hakra channel in Pakistan, many Indus Valley sites have been discovered along the Ghaggar-Hakra beds. Among them are, Rupar, Rakhigarhi, Sothi, Kalibangan, Harappan Civilisation remains the correct one, according to the common archaeological usage of naming a civilisation after its first findspot. John wrote, I was much exercised in my mind how we were to get ballast for the line of the railway and they were told of an ancient ruined city near the lines, called Brahminabad. Visiting the city, he found it full of hard well-burnt bricks, and, convinced there was a grand quarry for the ballast I wanted. These bricks now provided ballast along 93 miles of the track running from Karachi to Lahore. In 1872–75, Alexander Cunningham published the first Harappan seal and it was half a century later, in 1912, that more Harappan seals were discovered by J. J. H. MacKay, and Marshall. By 1931, much of Mohenjo-Daro had been excavated, but excavations continued, such as that led by Sir Mortimer Wheeler, director of the Archaeological Survey of India in 1944. Among other archaeologists who worked on IVC sites before the independence in 1947 were Ahmad Hasan Dani, Brij Basi Lal, Nani Gopal Majumdar, and Sir Marc Aurel Stein

Harappa
–
Harappa is an archaeological site in Punjab, Pakistan, about 24 km west of Sahiwal. The site takes its name from a village located near the former course of the Ravi River. The current village of Harappa is 6 km from the ancient site, although modern Harappa has a legacy railway station from the period of the British Raj, it is today just a small crossroads town of population 15,000. The site of the ancient city contains the ruins of a Bronze Age fortified city, which was part of the Cemetery H culture and the Indus Valley Civilization, centered in Sindh and the Punjab. Per archaeological convention of naming a previously unknown civilization by its first excavated site, the ancient city of Harappa was heavily damaged under British rule, when bricks from the ruins were used as track ballast in the construction of the Lahore-Multan Railway. In 2005, an amusement park scheme at the site was abandoned when builders unearthed many archaeological artifacts during the early stages of building work. A plea from the Pakistani archaeologist Ahmad Hasan Dani to the Ministry of Culture resulted in a restoration of the site, the Indus Valley Civilization has its earliest roots in cultures such as that of Mehrgarh, approximately 6000 BCE. The two greatest cities, Mohenjo-daro and Harappa, emerged circa 2600 BCE along the Indus River valley in Punjab, the bricks discovered were made of red sand, clay, stones and were baked at very high temperature. As early as 1826 Harappa located in west Punjab attracted the attention of a British officer in India, Indus Valley civilization was mainly an urban culture sustained by surplus agricultural production and commerce, the latter including trade with Sumer in southern Mesopotamia. Both Mohenjo-Daro and Harappa are generally characterized as having differentiated living quarters, flat-roofed brick houses, the weights and measures of the Indus Valley Civilization, on the other hand, were highly standardized, and conform to a set scale of gradations. Distinctive seals were used, among other applications, perhaps for identification of property, although copper and bronze were in use, iron was not yet employed. Wheel-made pottery—some of it adorned with animal and geometric motifs—has been found in profusion at all the major Indus sites, harappans had many trade routes along the Indus River that went as far as the Persian Gulf, Mesopotamia, and Egypt. Some of the most valuable things traded were carnelian and lapis lazuli, what is clear is that Harappan society was not entirely peaceful, with the human skeletal remains demonstrating some of the highest rates of injury found in South Asian prehistory. The excavators of the site have proposed the following chronology of Harappas occupation, Ravi Aspect of the Hakra phase, kot Dijian phase, c.2800 –2600 BC. Harappan Phase, c.2600 –1900 BC, transitional Phase, c.1900 –1800 BC. Late Harappan Phase, c.1800 –1300 BC, by far the most exquisite and obscure artifacts unearthed to date are the small, square steatite seals engraved with human or animal motifs. A large number of seals have been found at sites as Mohenjo-Daro. Many bear pictographic inscriptions generally thought to be a form of writing or script, despite the efforts of philologists from all parts of the world, and despite the use of modern cryptographic analysis, the signs remain undeciphered

Biological anthropology
–
It is a subfield of anthropology that provides a biological perspective to the systematic study of human beings. As a subfield of anthropology, biological anthropology itself is divided into several branches. All branches are united in their application of evolutionary theory to understanding human morphology. Primatology, the study of primate behavior, morphology. Reasons via homology and analogy to infer how and why similar human traits evolved, human behavioral ecology, the study of behavioral adaptations from the evolutionary and ecologic perspectives. Human adaptation, the study of human responses to environmental stresses. Bioarchaeology, the study of past human cultures through examination of human remains recovered in an archaeological context, the examined human remains usually comprises bones, but may include preserved soft tissue. Researchers in bioarchaeology combine the skillsets of human osteology, paleopathology, and archaeology, paleopathology is the study of disease in antiquity. Scientific physical anthropology began in the 18th century with the study of racial classification, the first prominent physical anthropologist, the German physician Johann Friedrich Blumenbach of Göttingen, amassed a large collection of human skulls. In 1897 Columbia University appointed Franz Boas as a physical anthropologist for his expertise in measuring schoolchildren, from his German education and training, Boas emphasized the mutability of the human form and minimized race in favor of culture. Ales Hrdlicka, a physician, studied anthropology in France under Leonce Manouvrier before working at the Smithsonian Institution from 1902. Earnest Hooton, a Classics PhD from the University of Wisconsin, entered anthropology as an Oxford Rhodes Scholar under R. R. Marett, there was much intellectual continuity with Germans such as Eugen Fischer, Fritz Lenz and Erwin Baur. In 1951 Sherwood Washburn, a Hooton alumnus, introduced a new physical anthropology and he changed the focus from racial typology to concentrate upon the study of human evolution, moving away from classification towards evolutionary process. Anthropology expanded to comprehend paleoanthropology and primatology, in contrast to much of medical anthropology, it does not generally take a critical approach to biomedicine and Western medicine. Instead, it seeks to improve medical practice and biomedical science through the integration of cross-cultural or biocultural, behavioral. As an academic discipline, biomedical anthropology is closely related to human biology, currently, the only accredited degree program in biomedical anthropology is at Binghamton University. Other anthropology departments, such as that of the University of Washington, anthropometry, the measurement of the human individual Craniometry Ethology Evolutionary biology Evolutionary psychology Paleontology Physiognomy Primatology Sociobiology Michael A

The University of Missouri is a public land-grant research university located in Columbia, Missouri, U. S. It was founded in 1839 as the first public institution of higher education west of the Mississippi River, as the largest university in the state, it enrolled 32,777 students in 2016, offering over 300 degree programs in 19 academic colleges in the 2014–2015 school year. It is the campus of the University of Missouri System, which also maintains campuses in Kansas City, Rolla. MU is one of the nations top-tier R1 institutions and one of the 34 public universities to be members of the Association of American Universities, there are more than 300,000 MU alumni living worldwide with over one half continuing to reside in Missouri. The university was ranked 103rd among national universities in the 2016 U. S. News & World Report rankings, starting in December 1953, it boasts the countrys only university-owned TV network affiliate, operated by the Missouri School of Journalism. In 1908, the worlds first school of journalism was founded by Walter Williams as the Missouri School of Journalism, the University of Missouri Research Reactor Center is the worlds most powerful university research reactor. MU is one of six public universities in the United States with a school of medicine, veterinary medicine, engineering, agriculture. The university also owns the University of Missouri Health Care system, the only athletic program that operates a NCAA Division I FBS football team in Missouri is known as the Missouri Tigers and competes as a member of the Southeastern Conference. The schools mascot, Truman the Tiger, is named after Missourian, according to the NCAA, the American tradition of homecoming was established at the university in 1911, the tradition has since been adopted nationwide. In 1839, the Missouri Legislature passed the Geyer Act to establish funds for a state university and it would be the first public university west of the Mississippi River. To secure the university, the citizens of Columbia and Boone County pledged $117,921 in cash, the land on which the university was eventually constructed was just south of Columbias downtown and owned by James S. Rollins. He was later called the Father of the University, as the first public university in the Louisiana Purchase, the school was shaped by Thomas Jeffersons ideas about public education. In 1862 the American Civil War forced the university to close for much of the year, residents of Columbia formed a home guard militia that became known as the Fighting Tigers of Columbia. They were given the name for their readiness to protect the city and university, in 1890, the universitys newly formed football team took the name the Tigers after the Civil War militia. In 1870 the institution was granted land-grant college status under the Morrill Act of 1862, the act led to the founding of the Missouri School of Mines and Metallurgy as an offshoot of the main campus in Columbia. It developed as the present-day Missouri University of Science and Technology, in 1888 the Missouri Agricultural Experiment Station opened. This grew to encompass ten centers and research farms around Missouri, by 1890 the university encompassed a normal college, engineering college, arts and science college, school of agriculture and mechanical arts. School of medicine, and school of law, on January 9,1892, Academic Hall, the institutions main building, burned in a fire that completely gutted the building, leaving little more standing than six stone Ionic columns

Mummy
–
Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 CE. Mummies of humans and other animals have found on every continent. Over one million animal mummies have been found in Egypt, many of which are cats, in addition to the well-known mummies of ancient Egypt, deliberate mummification was a feature of several ancient cultures in areas of America and Asia with very dry climates. The Spirit Cave mummies of Fallon, Nevada in North America were accurately dated at more than 9,400 years old. Before this discovery, the oldest known deliberate mummy was a child, one of the Chinchorro mummies found in the Camarones Valley, Chile, which dates around 5050 BCE. The oldest known naturally mummified corpse is a severed head dated as 6,000 years old. These substances were defined as mummia, the OED defines a mummy as the body of a human being or animal embalmed as a preparation for burial, citing sources from 1615 CE onward. However, Chambers Cyclopædia and the Victorian zoologist Francis Trevelyan Buckland define a mummy as follows, also applied to the frozen carcase of an animal imbedded in prehistoric snow. Wasps of the genus Aleiodes are known as mummy wasps because they wrap their prey as mummies. While interest in the study of mummies dates as far back as Ptolemaic Greece, prior to this, many rediscovered mummies were sold as curiosities or for use in pseudoscientific novelties such as mummia. The first modern scientific examinations of mummies began in 1901, conducted by professors at the English-language Government School of Medicine in Cairo, Egypt. The first X-ray of a mummy came in 1903, when professors Grafton Elliot Smith, British chemist Alfred Lucas applied chemical analyses to Egyptian mummies during this same period, which returned many results about the types of substances used in embalming. Lucas also made significant contributions to the analysis of Tutankhamun in 1922, pathological study of mummies saw varying levels of popularity throughout the 20th century. In 1992, the First World Congress on Mummy Studies was held in Puerto de la Cruz on Tenerife in the Canary Islands, more than 300 scientists attended the Congress to share nearly 100 years of collected data on mummies. This was not possible prior to the Congress due to the unique, in more recent years, CT scanning has become an invaluable tool in the study of mummification by allowing researchers to digitally unwrap mummies without risking damage to the body. The level of detail in such scans is so intricate that small linens used in areas such as the nostrils can be digitally reconstructed in 3-D. Such modelling has been utilized to perform autopsies on mummies to determine cause of death and lifestyle. Mummies are typically divided into one of two categories, anthropogenic or spontaneous

Bog
–
A bog is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four types of wetlands. Other names for bogs include mire, quagmire, and muskeg and they are frequently covered in ericaceous shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink, Bogs occur where the water at the ground surface is acidic and low in nutrients. In some cases, the water is derived entirely from precipitation, water flowing out of bogs has a characteristic brown colour, which comes from dissolved peat tannins. In general, the low fertility and cool climate results in relatively slow plant growth, large areas of landscape can be covered many metres deep in peat. Bogs have distinctive assemblages of animal, fungal and plant species, Bogs are widely distributed in cold, temperate climes, mostly in boreal ecosystems in the Northern Hemisphere. The worlds largest wetland is the bogs of the Western Siberian Lowlands in Russia. Large peat bogs also occur in North America, particularly the Hudson Bay Lowland and they are less common in the Southern Hemisphere, with the largest being the Magellanic moorland, comprising some 44,000 square kilometres. Sphagnum bogs were widespread in northern Europe but have often been cleared and drained for agriculture, a 2014 expedition leaving from Itanga village, Republic of the Congo discovered a peat bog as big as England which stretches into neighboring Democratic Republic of Congo. There are many highly specialised animals, fungi and plants associated with bog habitat, most are capable of tolerating the combination of low nutrient levels and waterlogging. Sphagnum moss is generally abundant, along with ericaceous shrubs, the shrubs are often evergreen, which is understood to assist in conservation of nutrients. In drier locations, evergreen trees can occur, in case the bog blends into the surrounding expanses of boreal evergreen forest. Sedges are one of the more common herbaceous species, carnivorous plants such as sundews and pitcher plants have adapted to the low-nutrient conditions by using invertebrates as a nutrient source. Orchids have adapted to these conditions through the use of fungi to extract nutrients. Some shrubs such as Myrica gale have root nodules in which nitrogen fixation occurs, Bogs are recognized as a significant/specific habitat type by a number of governmental and conservation agencies. They can provide habitat for mammals, such as caribou, moose, the United Kingdom in its Biodiversity Action Plan establishes bog habitats as a priority for conservation. Russia has a reserve system in the West Siberian Lowland

Ancient Egypt
–
Ancient Egypt was a civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. It is one of six civilizations to arise independently, Egyptian civilization followed prehistoric Egypt and coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh Narmer. In the aftermath of Alexander the Greats death, one of his generals, Ptolemy Soter and this Greek Ptolemaic Kingdom ruled Egypt until 30 BC, when, under Cleopatra, it fell to the Roman Empire and became a Roman province. The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture, the predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world and its monumental ruins have inspired the imaginations of travelers and writers for centuries. The Nile has been the lifeline of its region for much of human history, nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the climate of Northern Africa became increasingly hot and dry. In Predynastic and Early Dynastic times, the Egyptian climate was less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates, foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated. The largest of these cultures in upper Egypt was the Badari, which probably originated in the Western Desert, it was known for its high quality ceramics, stone tools. The Badari was followed by the Amratian and Gerzeh cultures, which brought a number of technological improvements, as early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East, particularly Canaan, establishing a power center at Hierakonpolis, and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile.
