Santa Maria, Rio Grande do Sul
Santa Maria is a municipality in the central region of Rio Grande do Sul, the southernmost state of Brazil. In 2017, its population was 278,445 inhabitants in a total area of 1,823 square kilometres. Santa Maria is the 5th biggest municipality in the state, the largest in its micro-region. Santa Maria is referred to as the "heart of Rio Grande", because the city is located in the geographical center of the State; the first inhabitants of Santa Maria were the Minuano Indigenous People, who lived in a region of the municipality known as Coxilha do Pau Fincado, the Tapes, who lived in the hills. With the arrival of Spanish and Portuguese colonizers this border region was witness to innumerable battles between rival groups. In 1797 the border between the two colonies was established by a commission; this commission set up camp on the site of present-day Santa Maria. The camp was known as Acampamento de Santa Maria adding Boca do Monte to the name. 1828 saw the arrival of the 28th Battalion of Foreigners, made up of hired Germans to fight against the inhabitants of present-day Uruguay in the Cisplatine War.
After the war many of the soldiers decided to stay in Santa Maria, beginning the cycle of German colonization. In 1857, Santa Maria was separated from Cachoeira elevated to town status; the municipality was created on 16 December 1857 and installed on 17 May 1858. Since 1910, the city is the seat of the Roman Catholic Diocese of Santa Maria, annually hosts an important Roman Catholic festival dedicated to Nossa Senhora Medianeira, called "Romaria da Medianeira"; every year, hundreds of thousands of people from all over Brazil join in the celebrations. Due to its strategic geographical location, Santa Maria has a large military force, including the Santa Maria Air Force Base of the Brazilian Air Force, which houses four units, the 3rd Army Division of the Southern Military Command. In 2011, the German defence company Krauss-Maffei Wegmann Co.. KG closed a deal to renovate old tanks and produce new ones for the Brazilian Army, opening a factory in Santa Maria; this earned the city its new nickname, "Armoured Capital".
On 27 January 2013, a fire broke out in the"Kiss" nightclub during a band performance, due to misuse of pyrotechnics, which got in direct contact with the acoustic foam used in the club. In total, 242 people died due to suffocation or trampling while trying to escape, or of complication in days and months following the event, it has been reported. Santa Maria is the fifth largest city in the state of Rio Grande do Sul, after Porto Alegre, Caxias do Sul and Canoas. Many of the city's inhabitants are of Italian ancestries, it is the largest city in the central region of the state, concentrating 36.40% of this region's population. During the period between 2000 and 2010, Santa Maria had a demographic growth rate of 6.00%. The municipality contains 10 districts; the city of Santa Maria itself is located in the urban Seat District, divided into 8 regiões administrativas, further subdivided into 40 bairros. About 95% of the municipality's total population is concentrated in the Seat District. One of the districts is Palma.
The economy is based on services, government services, agriculture. In 2006, there were 934 transformation industries employing 6,344 workers. Commerce employed 12,180 workers, public administration employed 4,783 workers, the health sector employed 3,799 workers, education employed 6,362 workers. In the agricultural sector, there were 2,335 establishments employing 7,000 workers; the main activities are cattle raising with over 100,000 head in 2006, growth of rice, corn and wheat. Santa Maria is a major railroad hub; the city has a strategic location in connecting Brazil to other Mercosul countries through the following highways: BR-158 – connects Santa Maria to northern and southwestern Rio Grande do Sul, allowing access to Uruguaiana, in the Argentine border, to Rivera, Uruguay. BR-287 – east-west highway, connecting the city to the capital of the state, Porto Alegre. Railways are used for cargo transportation of agricultural products, automobile parts and food. Santa Maria is 110 kilometres away from the River Terminal of Cachoeira do Sul, which allows ship transport until the port of Porto Alegre through the Jacuí River, from there to the Atlantic Ocean, through the Lagoa dos Patos.
Santa Maria Airport is located 12 km away in the neighborhood of Camobi. It has capacity for large airplanes and offers daily flights to Porto Alegre, Santo Ângelo and Uruguaiana; the same facility is shared by the Santa Maria Air Force Base of the Brazilian Air Force. Santa Maria—Porto Alegre: 286 km. Santa Maria—Pelotas: 337 km. Santa Maria—Cruz Alta: 135 km. Santa Maria—Uruguaiana: 365 km. Santa Maria—Passo Fundo: 293 km. Santa Maria—Caxias do Sul: 307 km. A popular nickname for Santa Maria is "University City" or "Culture city", due to its large student population; the largest university, the Federal University of Santa Maria, was founded in 1960 by José Mariano da Rocha Filho. The city has a number of other smaller private colleges, such as the Methodist University of Santa Maria – FAMES. Sant
Veterinary medicine is the branch of medicine that deals with the prevention and treatment of disease and injury in non-human animals. The scope of veterinary medicine is wide, covering all animal species, both domesticated and wild, with a wide range of conditions which can affect different species. Veterinary medicine is practiced, both with and without professional supervision. Professional care is most led by a veterinary physician, but by paraveterinary workers such as veterinary nurses or technicians; this can be augmented by other paraprofessionals with specific specialisms such as animal physiotherapy or dentistry, species relevant roles such as farriers. Veterinary science helps human health through the monitoring and control of zoonotic disease, food safety, indirectly through human applications from basic medical research, they help to maintain food supply through livestock health monitoring and treatment, mental health by keeping pets healthy and long living. Veterinary scientists collaborate with epidemiologists, other health or natural scientists depending on type of work.
Ethically, veterinarians are obliged to look after animal welfare. Archeological evidence, in the form of a cow skull upon which trepanation had been performed, shows that people were performing veterinary procedures in the Neolithic; the Egyptian Papyrus of Kahun is the first extant record of veterinary medicine. The Shalihotra Samhita, dating from the time of Ashoka, is an early Indian veterinary treatise; the edicts of Asoka read: "Everywhere King Piyadasi made two kinds of medicine available, medicine for people and medicine for animals. Where there were no healing herbs for people and animals, he ordered that they be bought and planted."Hippiatrica is a Byzantine compilation of hippiatrics, dated to the 5th or 6th century. The first attempts to organize and regulate the practice of treating animals tended to focus on horses because of their economic significance. In the Middle Ages, farriers combined their work in horseshoeing with the more general task of "horse doctoring"; the Arabic tradition of Bayṭara, or Shiyāt al-Khayl, originates with the treatise of Ibn Akhī Hizām.
In 1356, the Lord Mayor of London, concerned at the poor standard of care given to horses in the city, requested that all farriers operating within a seven-mile radius of the City of London form a "fellowship" to regulate and improve their practices. This led to the establishment of the Worshipful Company of Farriers in 1674. Meanwhile, Carlo Ruini's book Anatomia del Cavallo, was published in 1598, it was the first comprehensive treatise on the anatomy of a non-human species. The first veterinary school was founded in France in 1762 by Claude Bourgelat. According to Lupton, after observing the devastation being caused by cattle plague to the French herds, Bourgelat devoted his time to seeking out a remedy; this resulted in his founding a veterinary school in Lyon in 1761, from which establishment he dispatched students to combat the disease. The school received immediate international recognition in the eighteenth century and its pedagogical model drew on the existing fields of human medicine, natural history, comparative anatomy.
The Odiham Agricultural Society was founded in 1783 in England to promote agriculture and industry, played an important role in the foundation of the veterinary profession in Britain. A founding member, Thomas Burgess, began to take up the cause of animal welfare and campaign for the more humane treatment of sick animals. A 1785 Society meeting resolved to "promote the study of Farriery upon rational scientific principles." The physician James Clark wrote a treatise entitled Prevention of Disease in which he argued for the professionalization of the veterinary trade, the establishment of veterinary colleges. This was achieved in 1790, through the campaigning of Granville Penn, who persuaded the Frenchman, Benoit Vial de St. Bel to accept the professorship of the newly established Veterinary College in London; the Royal College of Veterinary Surgeons was established by royal charter in 1844. Veterinary science came of age in the late 19th century, with notable contributions from Sir John McFadyean, credited by many as having been the founder of modern Veterinary research.
In the United States, the first schools were established in the early 19th century in Boston, New York and Philadelphia. In 1879, Iowa Agricultural College became the first land grant college to establish a school of veterinary medicine. Veterinary care and management is led by a veterinary physician; this role is the equivalent of a doctor in human medicine, involves post-graduate study and qualification. In many countries, the local nomenclature for a vet is a protected term, meaning that people without the prerequisite qualifications and/or registration are not able to use the title, in many cases, the activities that may be undertaken by a vet are restricted only to those people who are registered as vet. For instance, in the United Kingdom, as in other jurisdictions, animal treatment may only be performed by registered vets, it is illegal for any person, not registered to call themselves a vet or perform any treatment. Most vets work in clinical s
Advertising is a marketing communication that employs an sponsored, non-personal message to promote or sell a product, service or idea. Sponsors of advertising are businesses wishing to promote their products or services. Advertising is differentiated from public relations in that an advertiser pays for and has control over the message, it differs from personal selling in that the message is non-personal, i.e. not directed to a particular individual. Advertising is communicated through various mass media, including traditional media such as newspapers, television, outdoor advertising or direct mail; the actual presentation of the message in a medium is referred to as an advertisement, or "ad" or advert for short. Commercial ads seek to generate increased consumption of their products or services through "branding", which associates a product name or image with certain qualities in the minds of consumers. On the other hand, ads that intend to elicit an immediate sale are known as direct-response advertising.
Non-commercial entities that advertise more than consumer products or services include political parties, interest groups, religious organizations and governmental agencies. Non-profit organizations may use free modes such as a public service announcement. Advertising may help to reassure employees or shareholders that a company is viable or successful. Modern advertising originated with the techniques introduced with tobacco advertising in the 1920s, most with the campaigns of Edward Bernays, considered the founder of modern, "Madison Avenue" advertising. Worldwide spending on advertising in 2015 amounted to an estimated US$529.43 billion. Advertising's projected distribution for 2017 was 40.4% on TV, 33.3% on digital, 9% on newspapers, 6.9% on magazines, 5.8% on outdoor and 4.3% on radio. Internationally, the largest advertising-agency groups are Dentsu, Omnicom, WPP. In Latin, advertere means "to turn towards". Egyptians used papyrus to make sales messages and wall posters. Commercial messages and political campaign displays have been found in the ruins of Pompeii and ancient Arabia.
Lost and found advertising on papyrus was common in ancient ancient Rome. Wall or rock painting for commercial advertising is another manifestation of an ancient advertising form, present to this day in many parts of Asia and South America; the tradition of wall painting can be traced back to Indian rock art paintings that date back to 4000 BC. In ancient China, the earliest advertising known was oral, as recorded in the Classic of Poetry of bamboo flutes played to sell confectionery. Advertisement takes in the form of calligraphic signboards and inked papers. A copper printing plate dated back to the Song dynasty used to print posters in the form of a square sheet of paper with a rabbit logo with "Jinan Liu's Fine Needle Shop" and "We buy high-quality steel rods and make fine-quality needles, to be ready for use at home in no time" written above and below is considered the world's earliest identified printed advertising medium. In Europe, as the towns and cities of the Middle Ages began to grow, the general population was unable to read, instead of signs that read "cobbler", "miller", "tailor", or "blacksmith", images associated with their trade would be used such as a boot, a suit, a hat, a clock, a diamond, a horseshoe, a candle or a bag of flour.
Fruits and vegetables were sold in the city square from the backs of carts and wagons and their proprietors used street callers to announce their whereabouts. The first compilation of such advertisements was gathered in "Les Crieries de Paris", a thirteenth-century poem by Guillaume de la Villeneuve. In the 18th century advertisements started to appear in weekly newspapers in England; these early print advertisements were used to promote books and newspapers, which became affordable with advances in the printing press. However, false advertising and so-called "quack" advertisements became a problem, which ushered in the regulation of advertising content. Thomas J. Barratt of London has been called "the father of modern advertising". Working for the Pears Soap company, Barratt created an effective advertising campaign for the company products, which involved the use of targeted slogans and phrases. One of his slogans, "Good morning. Have you used Pears' soap?" was famous in its day and into the 20th century.
Barratt introduced many of the crucial ideas that lie behind successful advertising and these were circulated in his day. He stressed the importance of a strong and exclusive brand image for Pears and of emphasizing the product's availability through saturation campaigns, he understood the importance of reevaluating the market for changing tastes and mores, stating in 1907 that "tastes change, fashions change, the advertiser has to change with them. An idea, effective a generation ago would fall flat and unprofitable if presented to the public today. Not that the idea of today is always better than the older idea, but it is different – it hits the present taste."As the economy expanded across the world during the 19th century, advertising grew alongside. In the United States, the success of this advertising format led to the growth of mail-order advertising. In June 1836, French newspaper La Presse was the first to include paid advertising in its pages, allowing it to lower its price, extend its readership and increase its profitability and the formula was soon copied by all titles.
Around 1840, Volney B. Palmer established the roo
Rio Grande do Sul
Rio Grande do Sul is a state located in the southern region of Brazil. It is the ninth largest by area. Located in the southernmost part of the country, Rio Grande do Sul is bordered clockwise by Santa Catarina to the north and northeast, the Atlantic Ocean to the east, the Uruguayan departments of Rocha, Treinta y Tres, Cerro Largo and Artigas to the south and southwest, the Argentine provinces of Corrientes and Misiones to the west and northwest; the capital and largest city is Porto Alegre. The state has the highest life expectancy in Brazil, the crime rate is considered to be low. Despite the high standard of living, unemployment is still high and according to census data, it is one of the most difficult states in Brazil for foreigners to find jobs; the state has a gaucho culture like its foreign neighbors. It was inhabited by Guarani people; the first Europeans there were Jesuits, followed by settlers from the Azores. In the 19th century it was the scene of conflicts including the Farroupilha Revolution and the Paraguayan War.
Large waves of German and Italian migration have shaped the state. Rio Grande do Sul is bordered to the northeast by the Brazilian State of Santa Catarina, to the southeast by the Atlantic Ocean, on the southwest by Uruguay, to the northwest by the Argentine provinces of Corrientes and Misiones; the northern part of the state lies on the southern slopes of the elevated plateau extending southward from São Paulo across the states of Paraná and Santa Catarina, is much broken by low mountain ranges whose general direction across the trend of the slope gives them the appearance of escarpments. A range of low mountains extends southward from the Serra do Mar of Santa Catarina and crosses the state into Uruguay. West of this range is a vast grassy plain devoted principally to stock-raising — the northern and most elevated part being suitable in pasturage and climate for sheep, the southern for cattle. East of it is a wide coastal zone only elevated above the sea; the coast is one great sand beach, broken only by the outlet of the two lakes, called the Rio Grande, which affords an entrance to navigable inland waters and several ports.
There are two distinct river systems in Rio Grande do Sul – that of the eastern slope draining to the lagoons, that of the Río de la Plata basin draining westward to the Uruguay River. The larger rivers of the eastern group are the Jacuí, Sinos, Caí, Gravataí and Camaquã, which flow into the Lagoa dos Patos, the Jaguarão which flows into the Lagoa Mirim. All of the first named, except the Camaquã, discharge into one of the two arms or estuaries opening into the northern end of Lagoa dos Patos, called the Guaíba River, though technically it is not a river but a lake; the Guaíba River is broad, comparatively deep and about 56 kilometres long, with the rivers discharging into it affords upwards of 320 kilometres of fluvial navigation. The Jacuí is one of the most important rivers of the state, rising in the ranges of the Coxilha Grande of the north and flowing south and southeast to the Guaíba estuary, with a course of nearly 480 kilometres It has two large tributaries, the Vacacaí from the south and the Taquari from the north, many small streams.
The Jaguarão, which forms part of the boundary line with Uruguay, is navigable 42 km up to and beyond the town of Jaguarão. In addition to the Lagoa dos Patos and Lagoa Mirim there are a number of small lakes on the sandy, swampy peninsulas that lie between the coast and these two, there are others of a similar character along the northern coast; the largest lake is the Lagoa dos Patos, which lies parallel with the coastline and southwest, is about 214 kilometres long exclusive of the two arms at its northern end, 40 58 km long and of its outlet, the Rio Grande, about 39 km long. Its width varies from 35 to 58 km; the lake is comparatively shallow and filled with sand banks, making its navigable channels tortuous and difficult. The Lagoa Mirim occupies a similar position farther south, on the Uruguayan border, is about 175 kilometres long by 10 to 35 km wide, it is more irregular in outline and discharges into Lagoa dos Patos through a navigable channel known as the São Gonçalo Channel. A part of the lake lies in Uruguayan territory, but its navigation, as determined by treaty, belongs to Brazil.
Both of these lakes are evidently the remains of an ancient depression in the coastline shut in by sand beaches built up by the combined action of wind and current. They are of the same level as the ocean, but their waters are affected by the tides and are brackish only a short distance above the Rio Grande outlet. One-third of the state belongs to the Río de la Plata drainage basin. Of the many streams flowing northward and westward to the Uruguay, the largest are the Ijuí of the plateau region, the Ibicuí, which has its source near Santa Maria in the central part of the state and flows westward to the Uruguay a short distance above Uruguaiana, the Quaraí River which forms part of the boundary line with Uruguay; the Uruguay River itself is formed by the confluence of the Pelotas rivers. The Pelotas, which has its source in the Serra do Mar on the Atlantic coast, the Uruguay River forms the northern and western boundary line of the state down to the mouth of the Quaraí, on the Uruguayan frontier.
Rio Grande do Sul lies within the south temperate zone and is predom
Chemistry is the scientific discipline involved with elements and compounds composed of atoms and ions: their composition, properties and the changes they undergo during a reaction with other substances. In the scope of its subject, chemistry occupies an intermediate position between physics and biology, it is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant chemistry, the formation of igneous rocks, how atmospheric ozone is formed and how environmental pollutants are degraded, the properties of the soil on the moon, how medications work, how to collect DNA evidence at a crime scene. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron; the word chemistry comes from alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, philosophy, astronomy and medicine.
It is seen as linked to the quest to turn lead or another common starting material into gold, though in ancient times the study encompassed many of the questions of modern chemistry being defined as the study of the composition of waters, growth, disembodying, drawing the spirits from bodies and bonding the spirits within bodies by the early 4th century Greek-Egyptian alchemist Zosimos. An alchemist was called a'chemist' in popular speech, the suffix "-ry" was added to this to describe the art of the chemist as "chemistry"; the modern word alchemy in turn is derived from the Arabic word al-kīmīā. In origin, the term is borrowed from the Greek χημία or χημεία; this may have Egyptian origins since al-kīmīā is derived from the Greek χημία, in turn derived from the word Kemet, the ancient name of Egypt in the Egyptian language. Alternately, al-kīmīā may derive from χημεία, meaning "cast together"; the current model of atomic structure is the quantum mechanical model. Traditional chemistry starts with the study of elementary particles, molecules, metals and other aggregates of matter.
This matter can be studied in isolation or in combination. The interactions and transformations that are studied in chemistry are the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together; such behaviors are studied in a chemistry laboratory. The chemistry laboratory stereotypically uses various forms of laboratory glassware; however glassware is not central to chemistry, a great deal of experimental chemistry is done without it. A chemical reaction is a transformation of some substances into one or more different substances; the basis of such a chemical transformation is the rearrangement of electrons in the chemical bonds between atoms. It can be symbolically depicted through a chemical equation, which involves atoms as subjects; the number of atoms on the left and the right in the equation for a chemical transformation is equal. The type of chemical reactions a substance may undergo and the energy changes that may accompany it are constrained by certain basic rules, known as chemical laws.
Energy and entropy considerations are invariably important in all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions, they can be analyzed using the tools of e.g. spectroscopy and chromatography. Scientists engaged in chemical research are known as chemists. Most chemists specialize in one or more sub-disciplines. Several concepts are essential for the study of chemistry; the particles that make up matter have rest mass as well – not all particles have rest mass, such as the photon. Matter can be a mixture of substances; the atom is the basic unit of chemistry. It consists of a dense core called the atomic nucleus surrounded by a space occupied by an electron cloud; the nucleus is made up of positively charged protons and uncharged neutrons, while the electron cloud consists of negatively charged electrons which orbit the nucleus. In a neutral atom, the negatively charged electrons balance out the positive charge of the protons.
The nucleus is dense. The atom is the smallest entity that can be envisaged to retain the chemical properties of the element, such as electronegativity, ionization potential, preferred oxidation state, coordination number, preferred types of bonds to form. A chemical element is a pure substance, composed of a single type of atom, characterized by its particular number of protons in the nuclei of its atoms, known as the atomic number and represented by the symbol Z; the mass number is the sum of the number of neutrons in a nucleus. Although all the nuclei of all atoms belonging to one element will have the same
Postgraduate education, or graduate education in North America, involves learning and studying for academic or professional degrees, academic or professional certificates, academic or professional diplomas, or other qualifications for which a first or bachelor's degree is required, it is considered to be part of higher education. In North America, this level is referred to as graduate school; the organization and structure of postgraduate education varies in different countries, as well as in different institutions within countries. This article outlines the basic types of courses and of teaching and examination methods, with some explanation of their history. There are two main types of degrees studied for at the postgraduate level: academic and vocational degrees; the term degree in this context means the moving from one stage or level to another, first appeared in the 13th century. Although systems of higher education date back to ancient Greece, ancient Rome, ancient India and Arabian Peninsula, the concept of postgraduate education depends upon the system of awarding degrees at different levels of study, can be traced to the workings of European medieval universities Italians.
University studies took six years for a bachelor's degree and up to twelve additional years for a master's degree or doctorate. The first six years taught the faculty of the arts, the study of the seven liberal arts: arithmetic, astronomy, music theory, grammar and rhetoric; the main emphasis was on logic. Once a Bachelor of Arts degree had been obtained, the student could choose one of three faculties—law, medicine, or theology—in which to pursue master's or doctor's degrees; the degrees of master and doctor were for some time equivalent, "the former being more in favour at Paris and the universities modeled after it, the latter at Bologna and its derivative universities. At Oxford and Cambridge a distinction came to be drawn between the Faculties of Law and Theology and the Faculty of Arts in this respect, the title of Doctor being used for the former, that of Master for the latter." Because theology was thought to be the highest of the subjects, the doctorate came to be thought of as higher than the master's.
The main significance of the higher, postgraduate degrees was that they licensed the holder to teach. In most countries, the hierarchy of postgraduate degrees is: Master's degrees; these are sometimes placed in a further hierarchy, starting with degrees such as the Master of Arts and Master of Science degrees the Master of Philosophy degree, the Master of Letters degree. In the UK, master's degrees may be taught or by research: taught master's degrees include the Master of Science and Master of Arts degrees which last one year and are worth 180 CATS credits, whereas the master's degrees by research include the Master of Research degree which lasts one year and is worth 180 CATS or 90 ECTS credits and the Master of Philosophy degree which lasts two years. In Scottish Universities, the Master of Philosophy degree tends to be by research or higher master's degree and the Master of Letters degree tends to be the taught or lower master's degree. In many fields such as clinical social work, or library science in North America, a master's is the terminal degree.
Professional degrees such as the Master of Architecture degree can last to three and a half years to satisfy professional requirements to be an architect. Professional degrees such as the Master of Business Administration degree can last up to two years to satisfy the requirement to become a knowledgeable business leader. Doctorates; these are further divided into academic and professional doctorates. An academic doctorate can be awarded as a Doctor of Philosophy degree or as a Doctor of Science degree; the Doctor of Science degree can be awarded in specific fields, such as a Doctor of Science in Mathematics degree, a Doctor of Agricultural Science degree, a Doctor of Business Administration degree, etc. In some parts of Europe, doctorates are divided into the Doctor of Philosophy degree or "junior doctorate", the "higher doctorates" such as the Doctor of Science degree, awarded to distinguished professors. A doctorate is the terminal degree in most fields. In the United States, there is little distinction between a Doctor of Philosophy degree and a Doctor of Science degree.
In the UK, Doctor of Philosophy degrees are equivalent to 540 CATS credits or 270 ECTS European credits, but this is not always the case as the credit structure of doctoral degrees is not defined. In some countries such as Finland and Sweden, there is the degree of Licentiate, more advanced than a master's degree but less so than a Doctorate. Credits required are about half of those required for a doctoral degree. Coursework requirements are the same as for a doctorate, but the extent of original research required is not as high as for doctorate. Medical doctors for example ar
Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It has been defined both as "the Science of Justice" and "the Art of Justice". Law is a system that regulates and ensures that individuals or a community adhere to the will of the state. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent in common law jurisdictions. Private individuals can create binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process; the formation of laws themselves may be influenced by a constitution, written or tacit, the rights encoded therein. The law shapes politics, economics and society in various ways and serves as a mediator of relations between people. A general distinction can be made between civil law jurisdictions, in which a legislature or other central body codifies and consolidates their laws, common law systems, where judge-made precedent is accepted as binding law.
Religious laws played a significant role in settling of secular matters, is still used in some religious communities. Islamic Sharia law is the world's most used religious law, is used as the primary legal system in some countries, such as Iran and Saudi Arabia; the adjudication of the law is divided into two main areas. Criminal law deals with conduct, considered harmful to social order and in which the guilty party may be imprisoned or fined. Civil law deals with the resolution of lawsuits between individuals and/or organizations. Law provides a source of scholarly inquiry into legal history, economic analysis and sociology. Law raises important and complex issues concerning equality and justice. Numerous definitions of law have been put forward over the centuries; the Third New International Dictionary from Merriam-Webster defines law as: "Law is a binding custom or practice of a community. The Dictionary of the History of Ideas published by Scribner's in 1973 defined the concept of law accordingly as: "A legal system is the most explicit, institutionalized, complex mode of regulating human conduct.
At the same time, it plays only one part in the congeries of rules which influence behavior, for social and moral rules of a less institutionalized kind are of great importance." There have been several attempts to produce "a universally acceptable definition of law". In 1972, one source indicated. McCoubrey and White said that the question "what is law?" has no simple answer. Glanville Williams said that the meaning of the word "law" depends on the context in which that word is used, he said that, for example, "early customary law" and "municipal law" were contexts where the word "law" had two different and irreconcilable meanings. Thurman Arnold said that it is obvious that it is impossible to define the word "law" and that it is equally obvious that the struggle to define that word should not be abandoned, it is possible to take the view that there is no need to define the word "law". The history of law links to the development of civilization. Ancient Egyptian law, dating as far back as 3000 BC, contained a civil code, broken into twelve books.
It was based on the concept of Ma'at, characterised by tradition, rhetorical speech, social equality and impartiality. By the 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code, which consisted of casuistic statements. Around 1760 BC, King Hammurabi further developed Babylonian law, by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae, for the entire public to see; the most intact copy of these stelae was discovered in the 19th century by British Assyriologists, has since been transliterated and translated into various languages, including English, Italian and French. The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society; the small Greek city-state, ancient Athens, from about the 8th century BC was the first society to be based on broad inclusion of its citizenry, excluding women and the slave class. However, Athens had no legal science or single word for "law", relying instead on the three-way distinction between divine law, human decree and custom.
Yet Ancient Greek law contained major constitutional innovations in the development of democracy. Roman law was influenced by Greek philosophy, but its detailed rules were developed by professional jurists and were sophisticated. Over the centuries between the rise and decline of the Roman Empire, law was adapted to cope with the changing social situations and underwent major codification under Theodosius II and Justinian I. Although codes were replaced by custom and case law during the Dark Ages, Roman law was rediscovered around the 11th century when medieval legal scholars began to research Roman codes and adapt their concepts. Latin legal maxims were compiled for guidance. In medieval England, royal
