Adobe Systems Incorporated /əˈdoʊbiː/ is an American multinational computer software company. The company is headquartered in San Jose, California, United States, Adobe has historically focused upon the creation of multimedia and creativity software products, with a more recent foray towards rich Internet application software development. It is best known for Photoshop, an image editing software, Acrobat Reader, Adobe was founded in February 1982 by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC in order to develop and sell the PostScript page description language. In 1985, Apple Computer licensed PostScript for use in its LaserWriter printers, as of 2015, Adobe Systems has about 13,500 employees, about 40% of whom work in San Jose. The name of the company, Adobe, comes from Adobe Creek in Los Altos, California, Adobes corporate logo features a stylized A and was designed by the wife of John Warnock, Marva Warnock, who is a graphic designer. Adobes first products after PostScript were digital fonts, which released in a proprietary format called Type 1. Apple subsequently developed a standard, TrueType, which provided full scalability and precise control of the pixel pattern created by the fonts outlines. In the mid-1980s, Adobe entered the software market with Illustrator. Illustrator, which grew from the firms in-house font-development software, helped popularize PostScript-enabled laser printers, Adobe Systems entered NASDAQ in 1986. Its revenue has grown from roughly $1 billion in 1999 to roughly $4 billion in 2012, Adobes fiscal years run from December to November. For example, the 2007 fiscal year ended on November 30,2007, in 1989, Adobe introduced what was to become its flagship product, a graphics editing program for the Macintosh called Photoshop. Stable and full-featured, Photoshop 1.0 was ably marketed by Adobe, in 1993, Adobe introduced PDF, the Portable Document Format, and its Adobe Acrobat and Reader software. PDF is now an International Standard, ISO 32000-1,2008, in December 1991, Adobe released Adobe Premiere, which Adobe rebranded as Adobe Premiere Pro in 2003. In 1992, Adobe acquired OCR Systems, Inc, in 1994, Adobe acquired Aldus and added PageMaker and After Effects to its product line later in the year, it also controls the TIFF file format. In 1995, Adobe added FrameMaker, the long-document DTP application, in 1996, Adobe Systems Inc added Ares Software Corp. In 2002, Adobe acquired Canadian company Accelio, on December 12,2005, Adobe acquired its main rival, Macromedia, in a stock swap valued at about $3. Adobe released Adobe Media Player in April 2008, on April 27, Adobe discontinued development and sales of its older HTML/web development software, GoLive in favor of Dreamweaver. Adobe offered a discount on Dreamweaver for GoLive users and supports those who still use GoLive with online tutorials, on June 1, Adobe launched Acrobat. com, a series of web applications geared for collaborative work

Adobo
–
Adobo or Adobar is the immersion of raw food in a stock composed variously of paprika, oregano, salt, garlic, and vinegar to preserve and enhance its flavor. The Portuguese variant is known as Carne de vinha dalhos, the practice is native to Iberia, namely Spanish cuisine and Portuguese cuisine. It was widely adopted in Latin America and other Spanish and Portuguese colonies, including the Azores, in the years following the discovery of the new world, meat and fish started to be preserved by new methods. Cold temperature facilitated the preservation of food, but the weather often did not provide low temperatures ideal for preservation, so it was necessary to other techniques. Animals were usually slaughtered in the coldest months of winter, and this was facilitated through the use of adobos along with paprika. Paprika gives a color to adobos and at the same time the capsaicins in paprika permit fats to dissolve to the point of allowing tissue penetration. Adobo was employed initially as a method of preservation. Traditional preparations were created with the intent of flavoring, such as cazón en adobo, berenjenas de Almagro, the noun form of adobo describes a marinade or seasoning mix. Recipes vary widely by region, Puerto Rican adobo, a rub used principally on meats, meat marinated or seasoned with an adobo is referred to as adobado or adobada. Adobo relates to marinated dishes such as chipotles en adobo in which chipotles are stewed in a sauce with tomatoes, garlic, vinegar, salt, the spices vary, but generally include several types of peppers, ground cumin and dried oregano. Some recipes include orange juice and lemon or lime juices and they often include a pinch of brown sugar just to offset any bitter taste. Puerto Rican-style adobo is a salt that is generously sprinkled or rubbed on meats and seafood prior to grilling, sautéing. There are two types of adobo on the island, the wet rub, adobo mojado, consists of crushed garlic, olive oil, salt, black pepper, dry or fresh orégano brujo, citrus juice or vinegar or a mix of both citrus and vinegar. More widely used on the island is a dry mix, adobo seco and it is easier to prepare and has a long shelf life. Adobo seco consists of powder, onion powder, salt, black pepper, dry orégano brujo. Adobo is a dish of Peruvian cuisine, specifically in the area of Arequipa. This is a dish of pork marinated in spices and vegetables, served with bread for dipping in the sauce. In Filipino cuisine, adobo refers to a cooking process indigenous to the Philippines

Palencia
–
Palencia is a city south of Tierra de Campos, in north-northwest Spain, the capital of the province of Palencia in the autonomous community of Castile and León. The municipality had a population of 81,522 in 2011, Palencia is located approximately 190 km north of Madrid, and some 40 km north of the capital of Valladolid. Two hills surround the city in its north-east area, on the closest stands the 30 metre high statue of Christ known as the Cristo del Otero, the fourth tallest statue of Christ in the world. Palencia has a substantial forest of 1,438 hectares 6 km away on a plateau above the city and this park is a popular amusement area for the locals. The Canal de Castilla runs close to the city, Palencias municipality includes the village of Paredes de Monte,14 km away. Fogs are also frequent because of the Carrion river, summer tends to be warm with temperatures that consistently surpass 30 °C in July and that can rarely reach 38 °C. Due to Palencias altitude, nightly temperatures tend to be cooler, precipitation levels are moderated, but precipitation can be observed throughout the year. Summer and winter are the driest seasons, with most rainfall occurring in the autumn, the rain is very frequent in winter, and infrequent in summer. Rainfall is light but frequent during the months, and infrequent in summer with heavy thunderstorms. The snow is an unfrecuently and light phenomenon at the city and it usually falls some days per year, during December, January and February, but it´s common watching some snowfalls during November or March. The fortified Celtiberian settlement is mentioned as Pallantia by Strabo and Ptolemy and it was the chief town of the Vaccaei, although Strabo wrongly assigns it to the Arevaci. The city was starved into submission by the Romans in the 2nd century BCE and incorporated into the province of Hispania Tarraconensis, though the little Roman garrison city was an active mint, it was insignificant compared to the Roman villas of Late Antiquity in the surrounding territory. Archeologists have uncovered the remains of Roman villas at La Olmeda and at the Quintanilla de la Cueza, when the Visigoths conquered the territory, however, they retained the Roman rural villa system in establishing the Campos Góticos. The Catholic bishopric of Palencia was founded in the 3rd century or earlier, assuming that its bishop was among those assembled in the 3rd century to depose Basilides, the Priscillianists which originated in Egypt but came to Spain was declared a heresy by the emperor Gratian. It was mix of orthodox Catholic beliefs and Gnostic/Montanist teachings, priscillian was ordained priest and then consecrated bishop of Avila. The heresy was strongest in northwestern Spain, the declaration of it as a heresy was a political move by the Catholic usurper emperor Maximus to curry favor with the Catholic emperors Valentinian II and Theodosius I. After the establishment of effective Visigothic power Catholics disputed the bishopric of Palencia with the Arian Visigoths, maurila, an Arian bishop established in Palencia by Leovigild, followed King Reccareds conversion to Catholicism, and in 589 he assisted at the Third Council of Toledo. When the Moors arrived in the early 8th century, resistance was fragmented among bishops in control of the walled towns

Coating
–
A coating is a covering that is applied to the surface of an object, usually referred to as the substrate. The purpose of applying the coating may be decorative, functional, the coating itself may be an all-over coating, completely covering the substrate, or it may only cover parts of the substrate. Functional coatings may be applied to change the properties of the substrate, such as adhesion, wetability, corrosion resistance. A further consideration for non-all-over coatings is that control is needed as to where the coating is to be applied, a number of these non-all-over coating processes are printing processes. Many industrial coating processes involve the application of a film of functional material to a substrate, such as paper, fabric, film, foil. If the substrate starts and ends the process wound up in a roll, a roll of substrate, when wound through the coating machine, is typically called a web. Coatings may be applied as liquids, gases or solids, metal coatings on plastic airframes Conductive coatings e. g. to manufacture some types of resistors Insulating coatings e. g. This method commonly implies slot-die coating above room temperature, but it also is possible to have hot-melt roller coating, hot-melt metering-rod coating, curtain coating- low viscosity, with the slot vertically above the web and a gap between slotdie and web. Slide coating- bead coating with a slide between the slotdie and the bead. Very successfully used for multilayer coating in the photographic industry, slot die bead coating- typically with the web backed by a roller and a very small gap between slotdie and web. Tensioned-web slotdie coating- with no backing for the web, inkjet printing Lithography Flexography Spin coating Dip coating Titanium and titanium alloys, edited by C. Leyens and M.

Shiraz
–
Shiraz is the sixth-most-populous city of Iran and the capital of Fars Province. At the 2011 census, the population of the city was 1,700,665, Shiraz is located in the southwest of Iran on the Roodkhaneye Khoshk seasonal river. It has a climate and has been a regional trade center for over a thousand years. Shiraz is one of the oldest cities of ancient Persia, the earliest reference to the city, as Tiraziš, is on Elamite clay tablets dated to 2000 BC. In the 13th century, Shiraz became a center of the arts and letters, due to the encouragement of its ruler. It was the capital of Persia during the Zand dynasty from 1750 until 1800, two famous poets of Iran, Hafez and Saadi, are from Shiraz, whose tombs are on the north side of the current city boundaries. Shiraz is known as the city of poets, literature, wine and it is also considered by many Iranians to be the city of gardens, due to the many gardens and fruit trees that can be seen in the city, for example Eram Garden. Shiraz has had major Jewish and Christian communities, the crafts of Shiraz consist of inlaid mosaic work of triangular design, silver-ware, pile carpet-weaving and weaving of kilim, called gilim and jajim in the villages and among the tribes. In Shiraz industries such as cement production, sugar, fertilizers, textile products, wood products, metalwork, Shirāz also has a major oil refinery and is also a major center for Irans electronic industries, 53% of Irans electronic investment has been centered in Shiraz. Shiraz is home to Irans first solar power plant, recently the citys first wind turbine has been installed above Babakoohi mountain near the city. The earliest reference to the city is on Elamite clay tablets dated to 2000 BCE, found in June 1970, the tablets written in ancient Elamite name a city called Tiraziš. Phonetically, this is interpreted as /tiračis/ or /ćiračis/ and this name became Old Persian /širājiš/, through regular sound change comes the modern Persian name Shirāz. The name Shiraz also appears on clay sealings found at a 2nd-century CE Sassanid ruin, by some of the native writers, the name Shiraz has derived from a son of Tahmuras, the third Shāh of the world according to Ferdowsis Shāhnāma. Shiraz is most likely more than 4,000 years old, the name Shiraz is mentioned in cuneiform inscriptions from around 2000 BC found in southwestern corner of the city. According to some Iranian mythological traditions, it was erected by Tahmuras Diveband. The oldest sample of wine in the world, dating to approximately 7,000 years ago, was discovered on clay jars recovered outside of Shiraz, in the Achaemenian era, Shiraz was on the way from Susa to Persepolis and Pasargadae. In Ferdowsis Shāhnāma it has said that Artabanus V, the Parthian Emperor of Iran. Ghasre Abu-Nasr which is originally from Parthian era is situated in this area, during the Sassanid era, Shiraz was in between the way which was connecting Bishapur and Gur to Istakhr

Iran
–
Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Mudbrick
–
A mudbrick is a brick, made of a mixture of loam, mud, sand and water mixed with a binding material such as rice husks or straw. In warm regions with little timber available to fuel a kiln. In some cases brickmakers extended the life of mud bricks by putting fired bricks on top or covering them with stucco, the Great Mosque of Djenné, in central Mali, is the worlds largest mudbrick structure. This plaster must be reapplied annually, the South Asian inhabitants of Mehrgarh constructed, and lived in, mud brick houses between 7000–3300 BC. Mud bricks used at more than 15 reported sites in 3rd millennium BC are attributed as major cultural trait in the ancient Indus valley civilization, mudbricks were in use in the Middle East during the Pre-Pottery Neolithic B period. The Mesopotamians used sun-dried bricks in their city construction, typically these bricks were flat on the bottom and curved on the top, some bricks were formed in a square mould and rounded so that the middle was thicker than the ends. In Ancient Egypt, workers gathered mud from the Nile river, workers then tramped on the mud while straw was added to solidify the mold. In Minoan Crete at the Knossos site there is evidence that sun-dried bricks were used in the Neolithic period. Mudbricks were used to some extent in pre-Roman Egypt, and mudbrick use increased at the time of Roman influence, adobe – Often used in the making of mudbricks.

Cob (material)
–
Cob, cobb or clom is a natural building material made from subsoil, water, some kind of fibrous organic material, and sometimes lime. The contents of subsoil naturally vary, and if it not contain the right mixture it can be modified with sand or clay. Cob is fireproof, resistant to seismic activity, and inexpensive and it can be used to create artistic, sculptural forms, and its use has been revived in recent years by the natural building and sustainability movements. In technical building and engineering such as the Uniform Building Code. Cob is an English term attested to around the year 1600 for an ancient building material that has used for building since prehistoric times. The etymology of cob and cobbing is unclear, but in several senses means to beat or strike, some of the oldest man-made structures in Afghanistan are composed of rammed earth and cob. Cobwork was used in the Maghreb and al-Andalus in the 11th and 12th centuries, Cob material is known by many names including adobe, lump clay, puddled clay, chalk mud, wichert, clay daubins, swish, torchis, bauge, bousille, and cat and clay. Cob structures can be found in a variety of climates across the globe, a number of cob cottages survive from mid-19th-century New Zealand. Traditionally, English cob was made by mixing the clay-based subsoil with sand, straw, English soils contain varying amounts of chalk, and cob made with significant amounts of chalk are called chalk cob or wychert. The earthen mixture was then ladled onto a foundation in courses. The construction would progress according to the time required for the course to dry. After drying, the walls would be trimmed and the next course built, with lintels for later such as doors. The walls of a cob house are generally about 24 inches thick, the thick walls provided excellent thermal mass which was easy to keep warm in winter and cool in summer. Walls with a thermal mass value act as a thermal buffer inside the home. The material has a long life-span even in rainy and/or humid climates, provided a tall foundation, Cob is fireproof, while fire cob is a refractory material, and historically, has been used to make chimneys, fireplaces, forges and crucibles. Without fiber, however, cob loses most of its tensile strength, when Kevin McCabe constructed a two-story, four bedroom cob house in England, UK in 1994, it was reputedly the first cob residence built in the country in 70 years. His techniques remained very traditional, the innovations he made were using a tractor to mix the cob and adding sand or shillet. From 2002 to 2004, sustainability enthusiast Rob Hopkins initiated the construction of a cob house for his family and it was a community project, but an unidentified arsonist destroyed it shortly before completion

Rammed earth
–
It is an ancient method that has been revived recently as a sustainable building material used in a technique of natural building. Rammed earth is simple to manufacture, non-combustible, thermally massive, strong, edifices formed of rammed earth are on every continent except Antarctica, in a range of environments including temperate, wet, semiarid desert, montane, and tropical regions. The availability of soil and a building design appropriate for local climatic conditions are the factors that favour its use. Historically, additives such as lime or animal blood were used to stabilize it, while modern construction adds lime, cement, to add variety, some modern builders also add coloured oxides or other materials, e. g. bottles, tires, or pieces of timber. The form must be durable and well braced, and the two opposing faces must be clamped together to prevent bulging or deformation caused by the large compressing forces. Damp material is poured into the formwork to a depth of 10 to 25 cm, the material is compressed iteratively, in batches or courses, so as to gradually erect the wall up to the top of the formwork. Tamping was historically manual with a ramming pole, and was very laborious. After a wall is complete, it is strong to immediately remove the formwork. This is necessary if a surface texture is to be applied, e. g. by wire brushing, carving, or mould impression, Construction is optimally done in warm weather so that the walls can dry and harden. The compression strength of the earth increases as it cures, some time is necessary for it to dry. Exposed walls must be sealed to prevent water damage, in modern variations of the technique, rammed-earth walls are constructed on top of conventional footings or a reinforced concrete slab base. Where blocks made of rammed earth are used, they are stacked like regular blocks and are bonded together with a thin mud slurry instead of cement. Special machines, usually powered by engines and often portable, are used to compress the material into blocks. Presently more than 30% of the population uses earth as a building material. Rammed earth has been used globally in a range of climatic conditions. Rammed-earth housing may resolve homelessness caused by otherwise expensive construction techniques, the compressive strength of rammed earth is a maximum of 4.3 MPa. This is less than that of concrete but more than sufficiently strong for domestic edifices, indeed, properly constructed rammed earth endures for thousands of years, as many ancient structures that are still standing around the world demonstrate. See 1960 Agadir earthquake for an example of the destruction which may be inflicted on such structures by an earthquake

Thermal mass
–
In building design, thermal mass is a property of the mass of a building which enables it to store heat, providing inertia against temperature fluctuations. It is sometimes known as the flywheel effect. Scientifically, thermal mass is equivalent to thermal capacitance or heat capacity and it is typically referred to by the symbol Cth and measured in units of J/°C or J/K. Thermal mass may also be used for bodies of water, machines or machine parts, living things, in those contexts, the term heat capacity is typically used instead. The equation relating thermal energy to thermal mass is, Q = C t h Δ T where Q is the energy transferred, Cth is the thermal mass of the body. For example, if 250 J of heat energy is added to a gear with a thermal mass of 38.46 J/°C. If the body consists of a material with sufficiently known physical properties. For discussion of why the energy storage abilities of pure substances vary. For bodies composed of different materials, the thermal masses for the different components can just be added together. Thermal mass is effective in improving building comfort in any place that experiences these types of daily temperature fluctuations—both in winter as well as in summer. When used well and combined with passive solar design, thermal mass can play an important role in major reductions to energy use in heating and cooling systems. Ideal materials for mass are those materials that have, high specific heat capacity, high density Any solid, liquid. A common misconception is that concrete or earth soil has thermal mass. A table of heat capacity for building materials is available here. The correct use and application of mass is dependent on the prevailing climate in a district. Thermal mass is placed within the building and situated where it still can be exposed to low-angle winter sunlight. In summer the thermal mass should be obscured from higher-angle summer sunlight in order to prevent overheating of the structure. The thermal mass is warmed passively by the sun or additionally by internal heating systems during the day, thermal energy stored in the mass is then released back into the interior during the night

1976 Guatemala earthquake
–
The 1976 Guatemala earthquake struck on February 4 at 03,01,43 local time with a moment magnitude of 7.5. The shock was centered on the Motagua Fault, about 160 km northeast of Guatemala City at a depth of 5 kilometers near the town of Los Amates in the department of Izabal. Cities throughout the country suffered damage, and most adobe type houses in the areas of Guatemala City were destroyed. The earthquake struck during the morning when most people were asleep. This contributed to the death toll of 23,000. Approximately 76,000 were injured, and many left homeless. Some of areas went without electricity and communications for days, the main shock was followed by thousands of aftershocks, some of the larger ones causing additional damage and loss of life. Average horizontal displacement along the Motagua fault was 100 cm, with a displacement of 326 cm. Maximum seismic intensity was located in the Mixco area, some sections of Guatemala City, a seismic intensity of MM VI covered an area of 33,000 km². Soil liquefaction and sand boils were observed in locations with high seismic intensity. The main quake activated secondary fault zones, including the Mixco fault, the most heavily affected area covered some 30,000 km², with a population of 2.5 million. Some 23,000 people were reported dead and 77,000 wounded, approximately 258,000 houses were destroyed, leaving about 1.2 million people homeless. 40% of the hospital infrastructure was destroyed, while other health facilities also suffered substantial damage. For example, the United States of America rebuilt most of the roads, several heavy aftershocks, ranging from 5.2 to 5.8 Mw caused additional casualties and hampered relief efforts.

2003 Bam earthquake
–
The 2003 Bam earthquake struck the Kerman province of southeastern Iran at 01,56 UTC on December 26. The shock had a moment magnitude of 6.6 and a maximum Mercalli intensity of IX, the earthquake was particularly destructive in Bam, with the death toll amounting to at least 26,271 people and injuring up to 30,000. The effects of the earthquake were exacerbated by the use of mud brick as the standard construction medium, in total a reported 44 countries sent in personnel to assist in relief operations and 60 countries offered assistance. Following the earthquake, the Iranian government seriously considered moving the capital of Tehran in fear of an earthquake occurring there, the earthquake had a psychological impact on many of the victims for years afterwards. A new institutional framework in Iran was established to address problems of urban planning, before the earthquake, Bam had a population of roughly 97,000. It is one of the most popular areas of Iran. During the Safavid dynasty Bam was a trading hub due to its location on the Silk Road. It gradually declined in significance after the Afghans invaded in 1722, the city became a tourist attraction in 1953, when restoration of Bams Old Quarter began. In October 2003, Bahram Akasheh, professor of geophysics at Tehran University, Iran suffers from frequent earthquakes, with minor quakes occurring almost daily. This earthquake occurred as a result of stresses generated by the Arabian plate moving northward against the Eurasian plate at approximately 3 centimetres per year, the Earths crust deforms in response to the plate motion in a broad zone that spans the width of Iran and extends into Turkmenistan. Earthquakes occur as the result of faulting and strike-slip faulting in the zone of deformation. However, field investigations will be necessary to find if the earthquake occurred on the Bam Fault or on another, the Bam earthquake is 100 kilometres south of the destructive earthquakes of June 11,1981 and July 28,1981. These earthquakes were caused by a combination of reverse-motion and strike-slip motion on the north-south oriented Gowk fault, the rupture length of the earthquake was estimated to be around 24 kilometers. Optical remote sensing data shows that the Bam fault is not a single fault, the fault ruptured by the Bam earthquake is believed to stretch the along northwest branch of this fault system from Bam southward. The quake occurred at 01,56 UTC on December 26,2003 and its epicenter was roughly 10 kilometres southwest of the ancient city of Bam. Maximum intensities were at Bam and Baravat, with the most damage concentrated within the 16 kilometres radius around the city, at least 26,271 people were killed and 30,000 injured. In terms of loss the quake was the worst to occur in Iranian history. The BBC reported that a number of victims were crushed while sleeping

2010 Chile earthquake
–
It was felt strongly in six Chilean regions, that together make up about 80 percent of the countrys population. According to the United States Geological Survey the cities experiencing the strongest shaking—VIII on the Mercalli intensity scale —were Concepción, Arauco, according to Chiles Seismological Service Concepción experienced the strongest shaking at MM IX. The earthquake was felt in the capital Santiago at MM VII or MM VIII, tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru, the earthquake triggered a tsunami which devastated several coastal towns in south-central Chile and damaged the port at Talcahuano.26 billion. The earthquake also generated a blackout that affected 93 percent of the Chilean population, President Michelle Bachelet declared a state of catastrophe and sent military troops to take control of the most affected areas. According to official sources,525 people lost their lives,25 people went missing, on 10 March, Swiss Reinsurance Co. estimated that the Chilean quake would cost insurance companies between 4 and 7 billion dollars. The rival German-based Munich Re AG made the same estimate, earthquakes losses to the economy of Chile are estimated at US$15–30 billion. According to the USGS the epicenter of the earthquake was about 3 km off the coast of Pelluhue commune in the Maule Region, Chiles Seismological Service located the quakes epicenter at about 34 km off the coast of Ñuble Province in the Biobío Region. This is 60 km north of Concepción and 170 km south-west of Talca, the earthquake took place along the boundary between the Nazca and South American tectonic plates, at a location where they converge at a rate of eighty millimeters a year. This earthquake was characterized by a focal mechanism, caused by the subduction of the Nazca plate beneath the South American Tectonic Plates. Chile has been at a convergent plate boundary that generates megathrust earthquakes since the Paleozoic era, in historical times the Chilean coast has suffered many megathrust earthquakes along this plate boundary, including the strongest earthquake ever measured, which is the 1960 Valdivia earthquake. Most recently, the boundary ruptured, causing the 2007 Tocopilla earthquake in northern Chile, the segment of the fault zone which ruptured in this earthquake was estimated to be over 700 km long with a displacement of almost 10 meters, or 120 years of accumulated plate movement. It lay immediately north of the 1,000 km segment which ruptured in the earthquake of 1960. Preliminary measurements show that the entire South American Plate moved abruptly westward during the quake, the earthquake also shifted other parts of South America from the Falkland Islands to Fortaleza, Brazil. For example, it moved Argentinas capital of Buenos Aires about one inch to the west, several cities south of Cobquecura were also raised, by up to 3 meters. The maximum recorded peak ground acceleration was at Concepcion, with a value of 0.65 g, an aftershock of 6.2 was recorded 20 minutes after the initial quake. Two more aftershocks of magnitudes 5.4 and 5.6 followed within an hour of the initial quake, the USGS said that a large vigorous aftershock sequence can be expected from this earthquake. By 6 March UTC, more than 130 aftershocks had been registered, shortly after the mainshock seismologists installed a dense network of seismometers along the whole rupture area

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

Western Asia
–
Western Asia, West Asia, Southwestern Asia or Southwest Asia is the westernmost subregion of Asia. The concept is in limited use, as it overlaps with the Middle East. The term is used for the purposes of grouping countries in statistics. The total population of Western Asia is an estimated 300 million as of 2015, in an unrelated context, the term is also used in ancient history and archaeology to divide the Fertile Crescent into the Asiatic or Western Asian cultures as opposed to ancient Egypt. As a geographic concept, Western Asia almost always includes the Levant, Mesopotamia, the term is used pragmatically and has no correct or generally agreed-upon definition. In contrast to this definition, the United Nations Industrial Development Organisation in its 2015 yearbook also includes Armenia and Azerbaijan, unlike the UNIDO, the United Nations Statistics Division excludes Iran from Western Asia and include Turkey, Georgia, and Cyprus in the region. These four countries are listed in the European category of the United Nations Educational, Scientific, the Olympic Council of Asias multi-sport event West Asian Games are contested by athletes representing these thirteen countries. Among the regions sports organisations are the West Asia Basketball Association, West Asian Billiards and Snooker Federation, West Asian Football Federation, Western Asia was in use as a geographical term in the early 19th century, even before Near East became current as a geopolitical concept. Use of the term in the context of contemporary geopolitics or world economy appears to date from the 1960s, Western Asia is located directly south of Eastern Europe. The region is surrounded by seven major seas, the Aegean Sea, the Black Sea, the Caspian Sea, the Persian Gulf, the Arabian Sea, the Red Sea, and the Mediterranean Sea. The Dasht-e Kavir and Dasht-e Lut deserts in eastern Iran naturally delimit the region somewhat from Asia itself, three major tectonic plates converge on Western Asia, including the African, Eurasian, and Arabian plates. The boundaries between the plates make up the Azores-Gibraltar Ridge, extending across North Africa, the Red Sea. The Arabian Plate is moving northward into the Anatolian plate at the East Anatolian Fault, several major aquifers provide water to large portions of Western Asia. In Saudi Arabia, two large aquifers of Palaeozoic and Triassic origins are located beneath the Jabal Tuwayq mountains and areas west to the Red Sea. Cretaceous and Eocene-origin aquifers are located beneath large portions of central and eastern Saudi Arabia, including Wasia, flood or furrow irrigation, as well as sprinkler methods, are extensively used for irrigation, covering nearly 90,000 km² across Western Asia for agriculture. Western Asia is primarily arid and semi-arid, and can be subject to drought, the region consists of grasslands, rangelands, deserts, and mountains. Water shortages are a problem in parts of West Asia, with rapidly growing populations increasing demands for water. Major rivers, including the Tigris and Euphrates, provide sources for water to support agriculture

North Africa
–
North Africa or Northern Africa is the northernmost region of Africa. The United Nationss definition of Northern Africa is, Algeria, Egypt, Libya, Morocco, Sudan, Tunisia, the countries of Algeria, Morocco, Tunisia, and Libya are often collectively referred to as the Maghreb, which is the Arabic word for sunset. Egypt lies to the northeast and encompasses part of West Asia, while Sudan is situated on the edge of the Sahel, Egypt is a transcontinental country because of the Sinai Peninsula, which geographically lies in Western Asia. North Africa also includes a number of Spanish possessions, the Canary Islands and Madeira in the North Atlantic Ocean northwest of the African mainland are included in considerations of the region. From 3500 BC, following the abrupt desertification of the Sahara due to changes in the Earths orbit. The Islamic influence in the area is significant, and North Africa is a major part of the Muslim world. Some researchers have postulated that North Africa rather than East Africa served as the point for the modern humans who first trekked out of the continent in the Out of Africa migration. The Atlas Mountains extend across much of Morocco, northern Algeria and Tunisia, are part of the mountain system that also runs through much of Southern Europe. They recede to the south and east, becoming a steppe landscape before meeting the Sahara desert, the sediments of the Sahara overlie an ancient plateau of crystalline rock, some of which is more than four billion years old. Sheltered valleys in the Atlas Mountains, the Nile Valley and Delta, a wide variety of valuable crops including cereals, rice and cotton, and woods such as cedar and cork, are grown. Typical Mediterranean crops, such as olives, figs, dates and citrus fruits, the Nile Valley is particularly fertile, and most of the population in Egypt and Sudan live close to the river. Elsewhere, irrigation is essential to improve yields on the desert margins. The inhabitants of Saharan Africa are generally divided in a manner corresponding to the principal geographic regions of North Africa, the Maghreb, the Nile valley. The edge of the Sahel, to the south of Egypt has mainly been inhabited by Nubians, Ancient Egyptians record extensive contact in their Western desert with people that appear to have been Berber or proto-Berber, as well as Nubians from the south. They have contributed to the Arabized Berber populations, the official language or one of the official languages in all of the countries in North Africa is Arabic. The people of the Maghreb and the Sahara regions speak Berber languages and several varieties of Arabic, the Arabic and Berber languages are distantly related, both being members of the Afroasiatic language family. The Tuareg Berber languages are more conservative than those of the coastal cities. Over the years, Berbers have been influenced by contact with cultures, Greeks, Phoenicians, Egyptians, Romans, Vandals, Arabs, Europeans

West Africa
–
West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. Early human settlers from northern Holocene societies arrived in West Africa around 12,000 B. C, sedentary farming began in, or around the fifth millennium B. C, as well as the domestication of cattle. By 1500 B. C, ironworking technology allowed an expansion of productivity. Northern tribes developed walled settlements and non-walled settlements that numbered at 400, in the forest region, Iron Age cultures began to flourish, and an inter-region trade began to appear. The desertification of the Sahara and the change of the coast cause trade with upper Mediterranean peoples to be seen. Local leather, cloth, and gold also contributed to the abundance of prosperity for many of the following empires. Also, based on the archaeology of city of Kumbi Saleh in modern-day Mauritania, three great kingdoms were identified in Bilad al-Sudan by the ninth century. They included Ghana, Gao and Kanem, the Sosso Empire sought to fill the void, but was defeated by the Mandinka forces of Sundiata Keita, founder of the new Mali Empire. In the 15th century, the Songhai would form a new dominant state based on Gao, in the Songhai Empire, under the leadership of Sonni Ali, further east, Oyo arose as the dominant Yoruba state and the Aro Confederacy as a dominant Igbo state in modern-day Nigeria. The Kingdom of Nri was a West African medieval state in the present-day southeastern Nigeria, the Kingdom of Nri was unusual in the history of world government in that its leader exercised no military power over his subjects. The kingdom existed as a sphere of religious and political influence over a third of Igboland, the Eze Nri managed trade and diplomacy on behalf of the Nri people, and possessed divine authority in religious matters. The Oyo Empire was a Yoruba empire of what is today Western, established in the 15th century, the Oyo Empire grew to become one of the largest West African states. It rose through the organizational skills of the Yoruba, wealth gained from trade. The Benin Empire was an empire located in what is now southern Nigeria. Its capital was Edo, now known as Benin City, Edo and it should not be confused with the modern-day country called Benin, formerly called Dahomey. The Benin Empire was one of the oldest and most highly developed states in the hinterland of West Africa. Olfert Dapper, a Dutch writer, describing Benin in his book Description of Africa and its craft was the most adored and treasured bronze casting in the history of Africa. It was annexed by the British Empire in 1897 during the invasion, in the early 19th century, a series of Fulani reformist jihads swept across Western Africa

South America
–
South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It may also be considered a subcontinent of the Americas, which is the used in nations that speak Romance languages. The reference to South America instead of other regions has increased in the last decades due to changing geopolitical dynamics. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean, North America and it includes twelve sovereign states, a part of France, and a non-sovereign area. In addition to this, the ABC islands of the Kingdom of the Netherlands, Trinidad and Tobago, South America has an area of 17,840,000 square kilometers. Its population as of 2005 has been estimated at more than 371,090,000, South America ranks fourth in area and fifth in population. Brazil is by far the most populous South American country, with more than half of the population, followed by Colombia, Argentina, Venezuela. In recent decades Brazil has also concentrated half of the regions GDP and has become a first regional power, most of the population lives near the continents western or eastern coasts while the interior and the far south are sparsely populated. Most of the continent lies in the tropics, the continents cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the majority of South Americans speak Portuguese or Spanish. South America occupies the portion of the Americas. The continent is delimited on the northwest by the Darién watershed along the Colombia–Panama border. Almost all of mainland South America sits on the South American Plate, South Americas major mineral resources are gold, silver, copper, iron ore, tin, and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies and this is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export. South America is one of the most biodiverse continents on earth, South America is home to many interesting and unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a proportion of the Earths species. Brazil is the largest country in South America, encompassing around half of the land area

North America
–
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16. 5% of the land area. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7. 5% of the worlds population, North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago, the Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the migrations and the arrival of European settlers during the Age of Discovery. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants, European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French, the Americas are usually accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass previously unknown by Europeans. In 1507, Waldseemüller produced a map, in which he placed the word America on the continent of South America. He explained the rationale for the name in the accompanying book Cosmographiae Introductio, for Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespuccis name, but in its feminine form America, following the examples of Europa, Asia and Africa. Later, other mapmakers extended the name America to the continent, In 1538. Some argue that the convention is to use the surname for naming discoveries except in the case of royalty, a minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of Amairick. Another is that the name is rooted in a Native American language, the term North America maintains various definitions in accordance with location and context. In Canadian English, North America may be used to refer to the United States, alternatively, usage sometimes includes Greenland and Mexico, as well as offshore islands

Spain
–
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Valencia, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and later by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians, Basques and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula. The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth

Eastern Europe
–
Eastern Europe, also known as East Europe, is the eastern part of the European continent. There is no consensus on the area it covers, partly because the term has a wide range of geopolitical, geographical, cultural. There are almost as many definitions of Eastern Europe as there are scholars of the region, a related United Nations paper adds that every assessment of spatial identities is essentially a social and cultural construct. One definition describes Eastern Europe as an entity, the region lying in Europe with main characteristics consisting in Byzantine, Orthodox. Another definition was created during the Cold War and used more or less synonymously with the term Eastern Bloc, a similar definition names the formerly communist European states outside the Soviet Union as Eastern Europe. Historians and social scientists generally view such definitions as outdated or relegating, several definitions of Eastern Europe exist today, but they often lack precision or are extremely general. These definitions vary both across cultures and among experts, even scientists, recently becoming more and more imprecise. The Ural Mountains, Ural River, and the Caucasus Mountains are the land border of the eastern edge of Europe. Eurovoc, a multilingual thesaurus maintained by the Publications Office of the European Union, provides entries for 23 EU languages, of these, those in italics are classified as Eastern Europe in this source. Other official web-pages of the European Union classify some of the countries as strictly Central European. The East–West Schism is the break of communion and theology between what are now the Eastern and Western churches which began in the 11th century and lasts until this very day and it divided Christianity in Europe, and consequently the world, into Western Christianity and Eastern Christianity. Since the Great Schism of 1054, Europe has been divided between Roman Catholic and Protestant churches in the West, and the Eastern Orthodox Christian churches in the east, due to this religious cleavage, Eastern Orthodox countries are often associated with Eastern Europe. A cleavage of this sort is, however, often problematic, for example, Greece is overwhelmingly Orthodox, the fall of the Iron Curtain brought the end of the East–West division in Europe, but this geopolitical concept is sometimes still used for quick reference by the media. The Baltic states have seats in the Nordic Council as observer states and they also are members of the Nordic-Baltic Eight whereas Eastern European countries formed their own alliance called the Visegrád Group. Estonia Latvia Lithuania The Caucasus nations may be included in the definitions of Eastern Europe, the extent of their geographic or political affiliation with Europe varies by country and source. All three states are members of the European Unions Eastern Partnership program and the Euronest Parliamentary Assembly, on 12 January 2002, the European Parliament noted that Armenia and Georgia may enter the EU in the future. Georgia — in modern geography, Georgia has been classified as part of Eastern Europe. Under the European Union’s geographic criteria, Georgia is viewed as part of Eastern Europe and is the only Caucasus country to be actively seeking EU membership and it is a member of Council of Europe and Eurocontrol

Indigenous peoples of the Americas
–
The indigenous peoples of the Americas are the pre-Columbian peoples of the Americas and their descendants. The term Amerindian is used in Quebec, the Guianas, Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaska Natives. Application of the term Indian originated with Christopher Columbus, who, in his search for Asia, eventually, the Americas came to be known as the West Indies, a name still used to refer to the islands of the Caribbean Sea. This led to the blanket term Indies and Indians for the indigenous inhabitants, although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in the Amazon basin, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time, although some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires. Many parts of the Americas are still populated by peoples, some countries have sizable populations, especially Belize, Bolivia, Chile, Ecuador, Greenland, Guatemala, Mexico. At least a different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Aymara, Guaraní, Mayan languages, many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization, and subsistence practices. Like most cultures, over time, cultures specific to many indigenous peoples have evolved to incorporate traditional aspects, some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples. The specifics of Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are the subject of ongoing research. According to archaeological and genetic evidence, North and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the bridge of Beringia that joined Siberia to northwest North America. Alaska was a glacial refugium because it had low snowfall, allowing a small population to exist, the Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska for thousands of years. Indigenous genetic studies suggest that the first inhabitants of the Americas share a single population, one that developed in isolation. The isolation of these peoples in Beringia might have lasted 10–20,000 years, around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets. Another route proposed involves migration - either on foot or using primitive boats - along the Pacific Northwest coast to the south, archeological evidence of the latter would have been covered by the sea level rise of more than 120 meters since the last ice age

Southwestern United States
–
The population of the area is around 11 million people, with over half that in Arizona, the most populous cities are Phoenix, El Paso, Las Vegas, Albuquerque, and Tucson. Most of the area was part of the Viceroyalty of New Spain in the Spanish Empire before becoming part of Mexico and it became part of the United States through the Treaty of Guadalupe Hidalgo and the Gadsden Purchase. The deserts dominate the southern and western reaches of the area, the two major rivers of the region are the Colorado River, running in the northern and western areas, and the Rio Grande, running in the south. Formed approximately 8000 years ago, the Chihuahuan Desert is a dry desert. The Chihuahuan Desert spreads across the portion of the region, covering from southeastern Arizona, across southern New Mexico. While it is the second largest desert in the United States, only a third of the desert is within the United States, El Paso is the major city in this desert, with other smaller cities being Las Cruces and Roswell in New Mexico. The Chihuahuan is a rain shadow desert, formed two mountain ranges which block oceanic precipitation from reaching the area. The most prolific plants in this region are agave, yucca and creosote bushes, when people think of the desert southwest, the landscape of the Sonoran Desert is what mostly comes to mind. Rainfall averages between 4–12 inches per year, and the deserts most widely known inhabitant is the saguaro cactus and it is bounded on the northwest by the Mojave Desert, to the north by the Colorado Plateau and to the east by the Arizona Mountains forests and the Chihuahuan Desert. The portion of the Sonora Desert which lies in the Southwestern United States is the most populated area within the region. Six of the top ten major population centers of the region are found within its borders, Phoenix, Tucson, Mesa, Chandler, Glendale, also within its borders are Yuma and Prescott Arizona. The most northwest portion of the American Southwest is covered by the Mojave Desert, bordered on the south by the Sonoran Desert and the east by the Colorado Plateau, its range within the region makes up the southeast tip of Nevada, and the northwestern corner of Arizona. In terms of topography, the Mojave is very similar to the Great Basin Desert, the Mojave is the smallest, driest and hottest desert within the United States. The Mojave gets less than six inches of rain annually, the most prolific vegetation is the tall Joshua tree, which grow as tall as 40 feet, and are thought to live almost 1000 years. Other major vegetation includes the Parry saltbush and the Mojave sage, the Colorado Plateau varies from the large stands of forests in the west, including the largest stand of ponderosa pine trees in the world, to the Mesas to the east. Although not called a desert, the Colorado Plateau is mostly made up of high desert, the Plateau is characterized by a series of plateaus and mesas, interspersed with canyons. The most dramatic example is the Grand Canyon, but that is one of many dramatic vistas included within the Plateau, which includes spectacular lava formations, painted deserts, sand dunes, and badlands. One of the most distinctive features of the Plateau is its longevity, the Plateau can be divided into six sections, three of which fall into the Southwest region

Mesoamerica
–
It is one of six areas in the world where ancient civilization arose independently, and the second in the Americas along with Norte Chico in present-day northern coastal Peru. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures, while Mesoamerican civilization did know of the wheel and basic metallurgy, neither of these technologies became culturally important. Among the earliest complex civilizations was the Olmec culture, which inhabited the Gulf coast of Mexico and extended inland, frequent contact and cultural interchange between the early Olmec and other cultures in Chiapas, Guatemala and Oaxaca laid the basis for the Mesoamerican cultural area. All this was facilitated by considerable regional communications in ancient Mesoamerica and this Formative period saw the spread of distinct religious and symbolic traditions, as well as artistic and architectural complexes. In the subsequent Preclassic period, complex urban polities began to develop among the Maya, with the rise of such as El Mirador, Calakmul and Tikal. Mesoamerica is one of three regions of the world where writing is known to have independently developed. Upon the collapse of Teotihuacán around AD600, competition between several important political centers in central Mexico, such as Xochicalco and Cholula, ensued. During the early period, Central Mexico was dominated by the Toltec culture, Oaxaca by the Mixtec. Towards the end of the period, the Aztecs of Central Mexico built a tributary empire covering most of central Mesoamerica. The distinct Mesoamerican cultural tradition ended with the Spanish conquest in the 16th century, over the next centuries, Mesoamerican indigenous cultures were gradually subjected to Spanish colonial rule. The exact geographic extent of Mesoamerica has varied through time, as the civilization extended North and South from its heartland in southern Mexico, Mesoamerica is recognized as a near-prototypical cultural area, and the term is now fully integrated in the standard terminology of pre-Columbian anthropological studies. Conversely, the sister terms Aridoamerica and Oasisamerica, which refer to northern Mexico, 10° and 22° northern latitude, Mesoamerica possesses a complex combination of ecological systems, topographic zones, and environmental contexts. A main distinction groups these different niches into two categories, the lowlands and the altiplanos, or highlands. In the low-lying regions, sub-tropical and tropical climates are most common, as is true for most of the coastline along the Pacific and Gulf of Mexico and the Caribbean Sea. The highlands show much more diversity, ranging from dry tropical to cold mountainous climates. The rainfall varies from the dry Oaxaca and north Yucatan to the humid southern Pacific, several distinct sub-regions within Mesoamerica are defined by a convergence of geographic and cultural attributes. These sub-regions are more conceptual than culturally meaningful, and the demarcation of their limits is not rigid, the Maya area, for example, can be divided into two general groups, the lowlands and highlands. The lowlands are further divided into the southern and northern Maya lowlands, the southern Maya lowlands are generally regarded as encompassing northern Guatemala, southern Campeche and Quintana Roo in Mexico, and Belize

Andes
–
The Andes or Andean Mountains are the longest continental mountain range in the world. They are a range of highlands along the western edge of South America. This range is about 7,000 km long, about 200 to 700 km wide, the Andes extend from north to south through seven South American countries, Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile. Along their length, the Andes are split into several ranges, the Andes are the location of several high plateaus – some of which host major cities, such as Quito, Bogotá, Arequipa, Medellín, Sucre, Mérida and La Paz. The Altiplano plateau is the worlds second-highest after the Tibetan plateau and these ranges are in turn grouped into three major divisions based on climate, the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes are the worlds highest mountain range outside of Asia, the highest mountain outside Asia, Mount Aconcagua, rises to an elevation of about 6,961 m above sea level. The peak of Chimborazo in the Ecuadorean Andes is farther from the Earths center than any other location on the Earths surface, the worlds highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to 6,893 m. The etymology of the word Andes has been debated, the majority consensus is that it derives from the Quechua word anti, which means east as in Antisuyu, one of the four regions of the Inca Empire. In the northern part of the Andes, the isolated Sierra Nevada de Santa Marta range is considered to be part of the Andes. The term cordillera comes from the Spanish word cordel, meaning rope, the Andes range is about 200 km wide throughout its length, except in the Bolivian flexure where it is about 640 kilometres wide. The Andes are the result of plate tectonics processes, caused by the subduction of oceanic crust beneath the South American plate. The main cause of the rise of the Andes is the compression of the rim of the South American Plate due to the subduction of the Nazca Plate. In the south, the Andes share a boundary with the former Patagonia Terrane. To the west, the Andes end at the Pacific Ocean, from a geographical approach, the Andes are considered to have their western boundaries marked by the appearance of coastal lowlands and a less rugged topography. The Andes Mountains also contain large quantities of iron ore located in mountains within the range. The Andean orogen has a series of bends or oroclines, the Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes Mountains at about 18° S. At this point the orientation of the Andes turns from Northwest in Peru to South in Chile, the Andean segment north and south of the orocline have been rotated 15° to 20° counter clockwise and clockwise respectively. The Bolivian Orocline area overlaps with the area of maximum width of the Altiplano Plateau, the specific point at 18° S where the coastline bends is known as the Arica Elbow

Puebloans
–
The Pueblo peoples speak languages from several different groups and are also divided culturally by their kinship systems and agricultural practices, although all cultivate varieties of corn. In addition to differing kinship systems, the peoples have differing marriage practices and those who have a matrilineal system, in which children are considered born into the mothers clan and her line is used for inheritance and descent, are the Hopi, Keres, Towa and Zuni. The non-Towa Tanoan have a system, with clan membership, inheritance. All the Pueblo peoples have traditional economies based on agriculture and trade, at the time of Spanish encounter beginning in the 16th century, these peoples were living in complex, multi-story villages often built around a central courtyard. The Spanish called these pueblos, meaning towns, and applied the name to all the living in such complexes. In the 21st century there are 21 surviving pueblos in the Southwest of the United States, Taos, Acoma, Zuni, and Hopi are the best-known. The main pueblos are located primarily in the states of New Mexico. Anthropologists have studied these peoples extensively and published various classifications of their subdivisions, in 1950, Fred Russell Eggan contrasted the peoples of the Eastern and Western Pueblos, based largely on their subsistence farming techniques. The Western or Desert Pueblos of the Zuñi and Hopi specialize in dry farming, in 1954, Paul Kirchhoff published a division of the Pueblo peoples into two groups based on culture, one includes the Hopi, Zuni, Keres and Jemez. They each have matrilineal kinship systems, children are considered born into their mothers clan and must marry a spouse outside it and they maintain multiple kivas for sacred ceremonies. Their creation myth tells that humans emerged from the underground and they emphasize four or six cardinal directions as part of their sacred cosmology, beginning in the north. Four and seven are considered significant in their rituals and symbolism. In contrast, the Tanoan-speaking Pueblos have a kinship system. They practice endogamy, or marriage within the clan and they have two kivas or two groups of kivas in their pueblos. Their belief system is based in dualism, the creation story recounts the emergence of the people from underwater. They use five directions, beginning in the west and their ritual numbers are based on multiples of three. The Pueblo peoples speak languages from different language families, demonstrating their diverse ethnic origins. The Hopi language is Uto-Aztecan, Zuni is an isolate, and Keresan is a dialect continuum that includes Acoma, Laguna, Santa Ana, Zia, Cochiti, Santo Domingo

Bronze Age
–
The Bronze Age is a historical period characterized by the use of bronze, proto-writing, and other early features of urban civilization. The Bronze Age is the principal period of the three-age Stone-Bronze-Iron system, as proposed in modern times by Christian Jürgensen Thomsen. An ancient civilization is defined to be in the Bronze Age either by smelting its own copper and alloying with tin, arsenic, or other metals, or by trading for bronze from production areas elsewhere. Copper-tin ores are rare, as reflected in the fact there were no tin bronzes in Western Asia before trading in bronze began in the third millennium BC. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition, although the Iron Age generally followed the Bronze Age, in some areas, the Iron Age intruded directly on the Neolithic. Bronze Age cultures differed in their development of the first writing, according to archaeological evidence, cultures in Mesopotamia and Egypt developed the earliest viable writing systems. The overall period is characterized by use of bronze, though the place and time of the introduction. Human-made tin bronze technology requires set production techniques, tin must be mined and smelted separately, then added to molten copper to make bronze alloy. The Bronze Age was a time of use of metals. The dating of the foil has been disputed, the Bronze Age in the ancient Near East began with the rise of Sumer in the 4th millennium BC. Societies in the region laid the foundations for astronomy and mathematics, the usual tripartite division into an Early, Middle and Late Bronze Age is not used. Instead, a division based on art-historical and historical characteristics is more common. The cities of the Ancient Near East housed several tens of thousands of people, ur in the Middle Bronze Age and Babylon in the Late Bronze Age similarly had large populations. The earliest mention of Babylonia appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC, the Amorite dynasty established the city-state of Babylon in the 19th century BC. Over 100 years later, it took over the other city-states. Babylonia adopted the written Semitic Akkadian language for official use, by that time, the Sumerian language was no longer spoken, but was still in religious use. Elam was an ancient civilization located to the east of Mesopotamia, in the Old Elamite period, Elam consisted of kingdoms on the Iranian plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a role in the Gutian Empire and especially during the Achaemenid dynasty that succeeded it

Iron Age
–
The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia with exceptions, meteoric iron has been used by humans since at least 3200 BC. Ancient iron production did not become widespread until the ability to smelt ore, remove impurities. The start of the Iron Age proper is considered by many to fall between around 1200 BC and 600 BC, depending on the region, the earliest known iron artifacts are nine small beads dated to 3200 BC, which were found in burials at Gerzeh, Lower Egypt. They have been identified as meteoric iron shaped by careful hammering, meteoric iron, a characteristic iron–nickel alloy, was used by various ancient peoples thousands of years before the Iron Age. Such iron, being in its metallic state, required no smelting of ores. Smelted iron appears sporadically in the record from the middle Bronze Age. While terrestrial iron is abundant, its high melting point of 1,538 °C placed it out of reach of common use until the end of the second millennium BC. Tins low melting point of 231, similarly, recent archaeological remains of iron working in the Ganges Valley in India have been tentatively dated to 1800 BC. By the Middle Bronze Age, increasing numbers of smelted iron objects appeared in the Middle East, Southeast Asia, African sites are turning up dates as early as 1200 BC. Modern archaeological evidence identifies the start of iron production in around 1200 BC. Between 1200 BC and 1000 BC, diffusion in the understanding of iron metallurgy and use of objects was fast. As evidence, many bronze implements were recycled into weapons during this time, more widespread use of iron led to improved steel-making technology at lower cost. Thus, even when tin became available again, iron was cheaper, stronger, and lighter, and forged iron implements superseded cast bronze tools permanently. Increasingly, the Iron Age in Europe is being seen as a part of the Bronze Age collapse in the ancient Near East, in ancient India, ancient Iran, and ancient Greece. In other regions of Europe, the Iron Age began in the 8th century BC in Central Europe, the Near Eastern Iron Age is divided into two subsections, Iron I and Iron II. Iron I illustrates both continuity and discontinuity with the previous Late Bronze Age, during the Iron Age, the best tools and weapons were made from steel, particularly alloys which were produced with a carbon content between approximately 0. 30% and 1. 2% by weight. Steel weapons and tools were nearly the same weight as those of bronze, however, steel was difficult to produce with the methods available, and alloys that were easier to make, such as wrought iron, were more common in lower-priced goods

San Pedro de Atacama
–
San Pedro de Atacama is a Chilean town and commune in El Loa Province, Antofagasta Region. It is located east of Antofagasta, some 106 km southeast of Calama and it features a significant archeological museum, the R. P. Gustavo Le Paige Archaeological Museum, with a large collection of relics and artifacts from the region. Native ruins nearby now attract increasing numbers of tourists interested in learning about pre-Columbian cultures, San Pedro de Atacama grew, over centuries, around an oasis in the Puna de Atacama, an arid high plateau. It was part of Bolivia since independence until Chile claimed ownership during the War of the Pacific, according to the 2002 census of the National Statistics Institute, San Pedro de Atacama had 4,969 inhabitants. Of these,1,938 lived in areas and 3,031 in rural areas. The population grew by 75. 6% between the 1992 and 2002 censuses, as a commune, San Pedro de Atacama is a third-level administrative division of Chile administered by a municipal council, headed by an alcalde who is directly elected every four years. The 2008-2012 alcalde is Sandra Berna Martínez, within the electoral divisions of Chile, San Pedro de Atacama is represented in the Chamber of Deputies by Marcos Espinosa and Felipe Ward as part of the 3rd electoral district. The commune is represented in the Senate by Alejandro Guillier Álvarez, the town lies at an average of 7,900 feet, and visitors often experience mild altitude sickness such as dizziness, lethargy and headaches. The local climate is dry and mild, with daytime temperatures between 25–30 degrees Celsius in the summer and 18–25 °C in the winter. Nighttime temperatures routinely drop below 0 °C and can reach as low as −10 °C in the winter, San Pedro lies on the main paved road from Argentina over the Paso de Jama,160 km from the town. There are frequent bus services to Calama, several buses daily to Santiago, nearby airports are San Pedro de Atacama Airport and Salar de Atacama Airport for private aircraft, and the larger El Loa Airport/Calama 100 km away for scheduled aircraft. Because of its altitude, a period of acclimatization may be required. In the town are some sites, R. P. Gustavo Le Paige Archaeological Museum, displaying ceramics. Church of San Pedro, Chile a National Monument, built with adobe, chaxas Lagoon, part of Los Flamencos National Reserve in the Salar de Atacama, inhabited by pink flamingos.

Chile
–
Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about 1,250,000 square kilometres of Antarctica, the arid Atacama Desert in northern Chile contains great mineral wealth, principally copper. Southern Chile is rich in forests and grazing lands, and features a string of volcanoes and lakes, the southern coast is a labyrinth of fjords, inlets, canals, twisting peninsulas, and islands. Spain conquered and colonized Chile in the century, replacing Inca rule in northern and central Chile. After declaring its independence from Spain in 1818, Chile emerged in the 1830s as a relatively stable authoritarian republic, in the 1960s and 1970s the country experienced severe left-right political polarization and turmoil. The regime, headed by Augusto Pinochet, ended in 1990 after it lost a referendum in 1988 and was succeeded by a coalition which ruled through four presidencies until 2010. Chile is today one of South Americas most stable and prosperous nations and it leads Latin American nations in rankings of human development, competitiveness, income per capita, globalization, state of peace, economic freedom, and low perception of corruption. It also ranks high regionally in sustainability of the state, Chile is a founding member of the United Nations, the Union of South American Nations and the Community of Latin American and Caribbean States. There are various theories about the origin of the word Chile, another theory points to the similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named Chili. Another origin attributed to chilli is the onomatopoeic cheele-cheele—the Mapuche imitation of the warble of a locally known as trile. The Spanish conquistadors heard about this name from the Incas, ultimately, Almagro is credited with the universalization of the name Chile, after naming the Mapocho valley as such. The older spelling Chili was in use in English until at least 1900 before switching over to Chile, stone tool evidence indicates humans sporadically frequented the Monte Verde valley area as long as 18,500 years ago. About 10,000 years ago, migrating Native Americans settled in fertile valleys, settlement sites from very early human habitation include Monte Verde, Cueva del Milodon and the Pali Aike Craters lava tube. They fought against the Sapa Inca Tupac Yupanqui and his army, the result of the bloody three-day confrontation known as the Battle of the Maule was that the Inca conquest of the territories of Chile ended at the Maule river. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors, the Spanish encountered various cultures that supported themselves principally through slash-and-burn agriculture and hunting. The conquest of Chile began in earnest in 1540 and was carried out by Pedro de Valdivia, one of Francisco Pizarros lieutenants, who founded the city of Santiago on 12 February 1541. Although the Spanish did not find the gold and silver they sought, they recognized the agricultural potential of Chiles central valley

Demotic (Egyptian)
–
The term was first used by the Greek historian Herodotus to distinguish it from hieratic and hieroglyphic scripts. By convention, the word Demotic is capitalized in order to distinguish it from demotic Greek, the Demotic script was referred to by the Egyptians as sš n šˤ. The script was used for more than a thousand years, and it is written and read from right to left, while earlier hieroglyphics could be written from top to bottom, left to right, or right to left. Early Demotic developed in Lower Egypt during the part of the 25th dynasty. It is generally dated between 650 and 400 BCE, as most texts written in Early Demotic are dated to the 26th dynasty, during this period, Demotic was used only for administrative, legal, and commercial texts, while hieroglyphs and hieratic were reserved for other texts. Middle Demotic is the stage of writing used during the Ptolemaic Period, from the 4th century BCE onward, Demotic held a higher status, as may be seen from its increasing use for literary and religious texts. From the beginning of Roman rule of Egypt, Demotic was progressively less used in public life. In contrast to the way Latin eliminated minority languages in the part of the Empire. After that, Demotic was only used for a few ostraca, subscriptions to Greek texts, mummy labels, and graffiti. The last dated example of the Demotic script is dated to December 11,452 CE, Demotic is a development of Late Egyptian and shares much with the later Coptic phase of the Egyptian language. In the earlier stages of Demotic, such as those written in the Early Demotic script. The Rosetta Stone was discovered in 1799 and it is inscribed with three scripts, classical Greek and both Demotic and hieroglyphic Egyptian. There are 32 lines of Demotic, which is the middle of the three scripts on the stone, the Demotic was deciphered before the hieroglyphs, starting with the efforts of Silvestre de Sacy. Egyptologists, linguists and papyrologists who specialize in the study of the Demotic stage of Egyptian script are known as Demotists, the table below shows some derivative similarities from Hieroglyphic to Demotic to the currently surviving Coptic Egyptian script.

Article (grammar)
–
An article is a word that is used alongside a noun to indicate the type of reference being made by the noun. Articles specify grammatical definiteness of the noun, in some extending to volume or numerical scope. The articles in the English language are the and a/an, an and a are modern forms of the Old English an, which in Anglian dialects was the number one and survived into Modern Scots as the number owan. Both on and an survived into Modern English, with one used as the number, in many languages, articles are a special part of speech, which cannot easily be combined with other parts of speech. In English, articles are considered a part of a broader speech category called determiners. In languages that employ articles, every common noun, with exceptions, is expressed with a certain definiteness. Every noun must be accompanied by the article, if any, corresponding to its definiteness, and this is in contrast to other adjectives and determiners, which are typically optional. This obligatory nature of articles makes them among the most common words in many languages—in English, for example, articles are usually characterized as either definite or indefinite. A few languages with well-developed systems of articles may distinguish additional subtypes, within each type, languages may have various forms of each article, according to grammatical attributes such as gender, number, or case, or according to adjacent sounds. The definite article is used to refer to a member of a group or class. It may be something that the speaker has already mentioned or it may be something uniquely specified, the definite article in English for both singular and plural nouns, is the. The children know the fastest way home, the sentence above refers to specific children and a specific way home, it contrasts with the much more general observation that, Children know the fastest ways home. The latter sentence refers to children in general and their specific ways home, refers to a specific book whose identity is known or obvious to the listener, as such it has a markedly different meaning from Give me a book. Which uses an indefinite article, which does not specify what book is to be given, the definite article can also be used in English to indicate a specific class among other classes, The cabbage white butterfly lays its eggs on members of the Brassica genus. However, recent developments show that definite articles are morphological elements linked to certain noun types due to lexicalization, under this point of view, definiteness does not play a role in the selection of a definite article more than the lexical entry attached to the article. The definite article is also used with proper names, which are already specified by definition. For example, the Amazon, the Hebrides, in these cases, the definite article may be considered superfluous. Its presence can be accounted for by the assumption that they are shorthand for a phrase in which the name is a specifier, i. e. the Amazon River

Santa Fe, New Mexico
–
Santa Fe is the capital of the state of New Mexico. It is the fourth-largest city in the state and is the seat of Santa Fe County and this area was occupied for at least several hundred years by indigenous peoples who built villages. The city of Santa Fe, founded by Spanish colonists in 1610, is known as the oldest state capital city in the United States, Santa Fe had a population of 69,204 in 2012. It is the city of a Metropolitan Statistical Area which encompasses all of Santa Fe County and is part of the larger Albuquerque–Santa Fe–Las Vegas combined statistical area. The citys full name when founded was La Villa Real de la Santa Fe de San Francisco de Asís, the area of Santa Fe was originally occupied by indigenous Tanoan peoples, who lived in numerous Pueblo villages along the Rio Grande. One of the earliest known settlements in what today is downtown Santa Fe came sometime after 900, the river had a year-round flow until the 1700s. By the 20th century the Santa Fe River was a seasonal waterway, as of 2007, the river was recognized as the most endangered river in the United States, according to the conservation group American Rivers. Don Juan de Oñate led the first European effort to colonize the region in 1598, under Juan de Oñate and his son, the capital of the province was the settlement of San Juan de los Caballeros north of Santa Fe near modern Ohkay Owingeh Pueblo. In 1610, he designated it as the capital of the province, Santa Fe remained Spains provincial seat until the outbreak of the Mexican War of Independence in 1810. It was considered important to fur traders based in present-day Saint Louis, when the area was still under Spanish rule, the Chouteau brothers of Saint Louis gained a monopoly on the fur trade, before the United States acquired Missouri under the Louisiana Purchase of 1803. The fur trade contributed to the wealth of St. Louis, the citys status as the capital of the Mexican territory of Santa Fe de Nuevo México was formalized in the 1824 Constitution after Mexico achieved independence from Spain. When the Republic of Texas seceded from Mexico in 1836, it claimed Santa Fe as part of the portion of Texas along the Rio Grande. In 1841, a military and trading expedition set out from Austin. Known as the Texan Santa Fe Expedition, the force was prepared and was easily captured by the Mexican army. In 1846, the United States declared war on Mexico, brigadier General Stephen W. Kearny led the main body of his Army of the West of some 1,700 soldiers into Santa Fe to claim it and the whole New Mexico Territory for the United States. By 1848 the U. S. officially gained New Mexico through the Treaty of Guadalupe Hidalgo, colonel Alexander William Doniphan, under the command of Kearny, recovered ammunition from Santa Fe labeled Spain 1776. This showed that New Mexico had received munitions and other support under Mexican rule, some American visitors at first saw little promise in the remote town. One traveller in 1849 wrote, I can hardly imagine how Santa Fe is supported, the country around it is barren

New Mexico
–
New Mexico is a state located in the southwestern region of the United States of America. It was admitted to the Union as the 47th state on January 6,1912 and it is usually considered one of the Mountain States. New Mexico is fifth by area, the 36th-most populous, inhabited by Native Americans for thousands of years before European exploration, New Mexico was colonized by the Spanish in 1598 Imperial Spanish viceroyalty of New Spain. Later, it was part of independent Mexico before becoming a U. S. territory and eventually a U. S. state as a result of the Mexican–American War. Among U. S. states, New Mexico has the highest percentage of Hispanics, the major Native American nations in the state are Navajo, Pueblo, and Apache peoples. The demography and culture of the state are shaped by these strong Hispanic and Native American influences and its scarlet and gold colors are taken from the royal standards of Spain, along with the ancient sun symbol of the Zia, a Pueblo-related tribe. New Mexico, or Nuevo México in Spanish, is incorrectly believed to have taken its name from the nation of Mexico. The name simply stuck, even though the area had no connection to Mexico or the Mexica Indian tribes, Mexico, formerly a part of New Spain, adopted its name centuries later in 1821, after winning independence from Spanish rule. New Mexico was a part of the independent Mexican Empire and Federal Republic of Mexico for 27 years,1821 through 1848, New Mexico and Mexico developed as neighboring Spanish-speaking communities under Spanish rule, with relatively independent histories. The states total area is 121,412 square miles, the eastern border of New Mexico lies along 103° W longitude with the state of Oklahoma, and 2.2 miles west of 103° W longitude with Texas. On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, the western border with Arizona runs along the 109°03 W longitude. The southwestern corner of the state is known as the Bootheel, the 37° N latitude parallel forms the northern boundary with Colorado. The states New Mexico, Colorado, Arizona, and Utah come together at the Four Corners in the corner of New Mexico. New Mexico, although a state, has very little water. Its surface water area is about 250 square miles, the New Mexican landscape ranges from wide, rose-colored deserts to broken mesas to high, snow-capped peaks. Despite New Mexicos arid image, heavily forested mountain wildernesses cover a significant portion of the state, the Sangre de Cristo Mountains, the southernmost part of the Rocky Mountains, run roughly north-south along the east side of the Rio Grande in the rugged, pastoral north. The most important of New Mexicos rivers are the Rio Grande, Pecos, Canadian, San Juan, the Rio Grande is tied for the fourth-longest river in the United States. Tourists visiting these sites bring significant money to the state, other areas of geographical and scenic interest include Kasha-Katuwe Tent Rocks National Monument and the Gila Wilderness in the southwest of the state

Composite material
–
The individual components remain separate and distinct within the finished structure. The new material may be preferred for reasons, common examples include materials which are stronger, lighter. More recently, researchers have begun to actively include sensing, actuation, computation and communication into composites. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments, the earliest man-made composite materials were straw and mud combined to form bricks for building construction. Ancient brick-making was documented by Egyptian tomb paintings, wattle and daub is one of the oldest man-made composite materials, at over 6000 years old. Concrete is also a material, and is used more than any other man-made material in the world. As of 2006, about 7.5 billion cubic metres of concrete are made each year—more than one metre for every person on Earth. 2181–2055 BC and was used for death masks Cob Mud Bricks, concrete was described by Vitruvius, writing around 25 BC in his Ten Books on Architecture, distinguished types of aggregate appropriate for the preparation of lime mortars. For structural mortars, he recommended pozzolana, which were volcanic sands from the beds of Pozzuoli brownish-yellow-gray in colour near Naples. Natural cement-stones, after burning, produced cements used in concretes from post-Roman times into the 20th century, the glass fiber is relatively strong and stiff, whereas the polymer is ductile. Thus the resulting fiberglass is relatively stiff, strong, flexible, concrete is the most common artificial composite material of all and typically consists of loose stones held with a matrix of cement. Concrete is a material, and will not compress or shatter even under quite a large compressive force. However, concrete cannot survive tensile loading, therefore, to give concrete the ability to resist being stretched, steel bars, which can resist high stretching forces, are often added to concrete to form reinforced concrete. Fibre-reinforced polymers or FRPs include carbon-fiber-reinforced polymer or CFRP, and glass-reinforced plastic or GRP, if classified by matrix then there are thermoplastic composites, short fiber thermoplastics, long fibre thermoplastics or long fibre-reinforced thermoplastics. There are numerous thermoset composites, including paper composite panels, many advanced thermoset polymer matrix systems usually incorporate aramid fibre and carbon fibre in an epoxy resin matrix. Shape memory polymer composites are high-performance composites, formulated using fibre or fabric reinforcement and they can also be reheated and reshaped repeatedly without losing their material properties. These composites are ideal for such as lightweight, rigid, deployable structures, rapid manufacturing. Although high strain composites exhibit many similarities to shape memory polymers, Composites can also use metal fibres reinforcing other metals, as in metal matrix composites or ceramic matrix composites, which includes bone, cermet and concrete

Straw
–
Straw is an agricultural by-product, the dry stalks of cereal plants, after the grain and chaff have been removed. Straw makes up half of the yield of cereal crops such as barley, oats, rice, rye. It has many uses, including fuel, livestock bedding and fodder and it is usually gathered and stored in a straw bale, which is a bundle of straw tightly bound with twine or wire. Bales may be square, rectangular, or round, depending on the type of baler used. Current and historic uses of straw include, Animal feed Straw may be fed as part of the component of the diet to cattle or horses that are on a near maintenance level of energy requirement. It has a low energy and nutrient content. The heat generated when microorganisms in a herbivores gut digest straw can be useful in maintaining body temperature in cold climates, due to the risk of impaction and its poor nutrient profile, it should always be restricted to part of the diet. It may be fed as it is, or chopped into short lengths, basketry Bee skeps and linen baskets are made from coiled and bound together continuous lengths of straw. The technique is known as lip work, bedding, humans or livestock The straw-filled mattress, also known as a palliasse, is still used in many parts of the world. It is commonly used as bedding for ruminants and horses and it may be used as bedding and food for small animals, but this often leads to injuries to mouth, nose and eyes as straw is quite sharp. Biofuels The use of straw as an energy source is increasing rapidly, especially for biobutanol. Straw or hay briquettes are a substitute to coal. Biogas Straw, processed first as briquettes, has been fed into a plant in Aarhus University, Denmark. Biomass The use of straw in large-scale biomass power plants is becoming mainstream in the EU, the straw is either used directly in the form of bales, or densified into pellets which allows for the feedstock to be transported over longer distances. Finally, torrefaction of straw with pelletisation is gaining attention, because it increases the density of the resource. This processing step also makes storage easier, because torrefied straw pellets are hydrophobic. Torrefied straw in the form of pellets can be directly co-fired with coal or natural gas at high rates and make use of the processing infrastructures at existing coal. Because the torrefied straw pellets have superior structural, chemical and combustion properties to coal, they can replace all coal, first generation pellets are limited to a co-firing rate of 15% in modern IGCC plants

Feces
–
Feces or faeces are the solid or semisolid metabolic waste from an animals digestive tract, discharged through the anus or cloaca during a process called defecation. Urine and feces together are called excreta, collected feces has various uses, namely as fertilizer or soil conditioner in agriculture, as a fuel source, or for medicinal purposes. After an animal has digested eaten material, the remains of material are discharged from its body as waste. Although it is lower in energy than the food from which it is derived, feces may retain a large amount of energy and this means that of all food eaten, a significant amount of energy remains for the decomposers of ecosystems. Many organisms feed on feces, from bacteria to fungi to insects such as dung beetles, some may specialize in feces, while others may eat other foods as well. Feces serve not only as a food, but also as a supplement to the usual diet of some animals. Feces and urine, which reflect light, are important to raptors such as kestrels. Seeds also may be found in feces, animals who eat fruit are known as frugivores. An advantage for a plant in having fruit is that animals will eat the fruit and this mode of seed dispersal is highly successful, as seeds dispersed around the base of a plant are unlikely to succeed and often are subject to heavy predation. Provided the seed can withstand the pathway through the system, it is not only likely to be far away from the parent plant. This cycling of matter is known as the biogeochemical cycle, the distinctive odor of feces is due to bacterial action. Gut flora produce compounds such as indole, skatole, and thiols and these are the same compounds that are responsible for the odor of flatulence. Consumption of foods prepared with spices may result in the spices being undigested, the perceived bad odor of feces has been hypothesized to be a deterrent for humans, as consuming or touching it may result in sickness or infection. Human perception of the odor may be contrasted by an animals perception of it, for example. In humans and depending on the individual and the circumstances, defecation may occur daily, extensive hardening of the feces may cause prolonged interruption in the routine and is called constipation. Human fecal matter varies significantly in appearance, depending on diet, normally it is semisolid, with a mucus coating. The brown coloration comes from a combination of bile and bilirubin, in newborn babies, initially fecal matter is yellow-green after the meconium. This coloration comes from the presence of bile alone, throughout the life of an ordinary human, one may experience many types of feces

Soil is a mixture of minerals, organic matter, gases, liquids, and countless organisms that together support life on Earth. Soil is called the Skin of the Earth and interfaces with the lithosphere, the hydrosphere, the atmosphere, the term pedolith, used commonly to refer to the soil, literally translates ground stone. Soil consists of a phase of minerals and organic matter, as well as a porous phase that holds gases. Accordingly, soils are often treated as a system of solids, liquids. Soil is a product of the influence of climate, relief, organisms, Soil continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness soil has been considered as an ecosystem by soil ecologists. Most soils have a dry bulk density between 1.1 and 1.6 g/cm3, while the particle density is much higher. Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic, Soil science has two basic branches of study, edaphology and pedology. Edaphology is concerned with the influence of soils on living things, pedology is focused on the formation, description, and classification of soils in their natural environment. In engineering terms, soil is referred to as regolith, or loose material that lies above the solid geology. Soil is commonly referred to as earth or dirt, technically, as soil resources serve as a basis for food security, the international community advocates its sustainable and responsible use through different types of soil governance. Soil is a component of the Earths ecosystem. The worlds ecosystems are impacted in far-reaching ways by the carried out in the soil, from ozone depletion and global warming, to rainforest destruction. Following the atmosphere, the soil is the next largest carbon reservoir on Earth, as the planet warms, soils will add carbon dioxide to the atmosphere due to its increased biological activity at higher temperatures. Thus, soil carbon losses likely have a positive feedback response to global warming. Since soil has a range of available niches and habitats. A gram of soil can contain billions of organisms, belonging to thousands of species, mostly microbial, Soil has a mean prokaryotic density of roughly 108 organisms per gram, whereas the ocean has no more than 107 procaryotic organisms per milliliter of seawater. Since plant roots need oxygen, ventilation is an important characteristic of soil and this ventilation can be accomplished via networks of interconnected soil pores, which also absorb and hold rainwater making it readily available for plant uptake

Sand
–
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt, Sand can also refer to a textural class of soil or soil type, i. e. a soil containing more than 85% sand-sized particles by mass. The second most common type of sand is calcium carbonate, for example aragonite, for example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Sand is a non renewable resource over human timescales, and sand suitable for making concrete is in high demand, in terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm to 2 mm. An individual particle in this size is termed a sand grain. Sand grains are between gravel and silt, a 1953 engineering standard published by the American Association of State Highway and Transportation Officials set the minimum sand size at 0.074 mm. A1938 specification of the United States Department of Agriculture was 0.05 mm. Sand feels gritty when rubbed between the fingers. ISO14688 grades sands as fine, medium and coarse with ranges 0.063 mm to 0.2 mm to 0.63 mm to 2.0 mm. In the United States, sand is commonly divided into five sub-categories based on size, very fine sand, fine sand, medium sand, coarse sand, and very coarse sand. These sizes are based on the Krumbein phi scale, where size in Φ = -log2D, on this scale, for sand the value of Φ varies from −1 to +4, with the divisions between sub-categories at whole numbers. The composition of sand is highly variable, depending on the local rock sources. The gypsum sand dunes of the White Sands National Monument in New Mexico are famous for their bright, arkose is a sand or sandstone with considerable feldspar content, derived from weathering and erosion of a granitic rock outcrop. Some sands contain magnetite, chlorite, glauconite or gypsum, Sands rich in magnetite are dark to black in color, as are sands derived from volcanic basalts and obsidian. Chlorite-glauconite bearing sands are typically green in color, as are sands derived from basaltic with a high olivine content, many sands, especially those found extensively in Southern Europe, have iron impurities within the quartz crystals of the sand, giving a deep yellow color. Sand deposits in some areas contain garnets and other resistant minerals, the study of individual grains can reveal much historical information as to the origin and kind of transport of the grain. Quartz sand that is weathered from granite or gneiss quartz crystals will be angular. It is called grus in geology or sharp sand in the trade where it is preferred for concrete. Sand that is transported long distances by water or wind will be rounded, people who collect sand as a hobby are known as arenophiles

Silt
–
Silt is granular material of a size between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil or as sediment mixed in suspension with water in a body of such as a river. It may also exist as soil deposited at the bottom of a water body, Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet, Silt can be visually observed with a hand lens. Silt is created by a variety of physical processes capable of splitting the generally sand-sized quartz crystals of primary rocks by exploiting deficiencies in their lattice and these involve chemical weathering of rock and regolith, and a number of physical weathering processes such as frost shattering and haloclasty. The main process is abrasion through transport, including fluvial comminution, aeolian attrition and it is in semi-arid environments that substantial quantities of silt are produced. Silt is sometimes known as rock flour or stone dust, especially produced by glacial action. Mineralogically, silt is composed mainly of quartz and feldspar, sedimentary rock composed mainly of silt is known as siltstone. Liquefaction created by an earthquake is silt suspended in water that is hydrodynamically forced up from below ground level. In the Udden–Wentworth scale, silt particles range between 0.0039 and 0.0625 mm, larger than clay but smaller than sand particles, ISO14688 grades silts between 0.002 mm and 0.063 mm. In actuality, silt is chemically distinct from clay, and unlike clay, grains of silt are approximately the size in all dimensions, furthermore. Clays are formed from thin plate-shaped particles held together by electrostatic forces, according to the U. S. Department of Agriculture Soil Texture Classification system, the sand-silt distinction is made at the 0.05 mm particle size. The USDA system has been adopted by the Food and Agriculture Organization, in the Unified Soil Classification System and the AASHTO Soil Classification system, the sand-silt distinction is made at the 0.075 mm particle size. Silts and clays are distinguished mechanically by their plasticity, Silt is easily transported in water or other liquid and is fine enough to be carried long distances by air in the form of dust. Thick deposits of silty material resulting from deposition by aeolian processes are called loess. Silt and clay contribute to turbidity in water, Silt is transported by streams or by water currents in the ocean. When silt appears as a pollutant in water the phenomenon is known as siltation, Silt, deposited by annual floods along the Nile River, created the rich, fertile soil that sustained the Ancient Egyptian civilization. In south east Bangladesh, in the Noakhali district, cross dams were built in the 1960s whereby silt gradually started forming new land called chars, the district of Noakhali has gained more than 28 square miles of land in the past 50 years

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

Cement
–
A cement is a binder, a substance used in construction that sets, hardens and adheres to other materials, binding them together. Cement is seldom used solely, but is used to bind sand, Cement is used with fine aggregate to produce mortar for masonry, or with sand and gravel aggregates to produce concrete. Non-hydraulic cement will not set in wet conditions or underwater, rather, it sets as it dries and it is resistant to attack by chemicals after setting. Hydraulic cements set and become adhesive due to a reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and this allows setting in wet condition or underwater and further protects the hardened material from chemical attack. The chemical process for hydraulic cement found by ancient Romans used volcanic ash with added lime, the word cement can be traced back to the Roman term opus caementicium, used to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick supplements that were added to the burnt lime, to obtain a hydraulic binder, were referred to as cementum, cimentum, cäment. In modern times, organic polymers are used as cements in concrete. Non-hydraulic cement, such as slaked lime, hardens by carbonation in the presence of carbon dioxide which is present in the air. The carbonation reaction requires the dry cement to be exposed to air and this whole process is called the lime cycle. Conversely, hydraulic cement hardens by hydration when water is added, Hydraulic cements are made of a mixture of silicates and oxides, the four main components being, Belite, Alite, Tricalcium aluminate, Brownmillerite. The chemistry of the above listed reactions is not completely clear and is still the object of research, Cement, chemically speaking, is a product that includes lime as the primary curing ingredient, but is far from the first material used for cementation. The Babylonians and Assyrians used bitumen to bind together burnt brick or alabaster slabs, in Egypt stone blocks were cemented together with a mortar made of sand and roughly burnt gypsum, which often contained calcium carbonate. Lime was used on Crete and by the ancient Greeks, there is evidence that the Minoans of Crete used crushed potshards as an artificial pozzolan for hydraulic cement. A kind of powder which from natural causes produces astonishing results and it is found in the neighborhood of Baiae and in the country belonging to the towns round about Mt. Vesuvius. This substance when mixed with lime and rubble not only lends strength to buildings of other kinds, the Greeks used volcanic tuff from the island of Thera as their pozzolan and the Romans used crushed volcanic ash with lime. This mixture was able to set under water increasing its resistance, the material was called pozzolana from the town of Pozzuoli, west of Naples where volcanic ash was extracted. In the absence of ash, the Romans used powdered brick or pottery as a substitute

listen), UK: /əˈdoʊb/;[1] Spanish: [aˈðoβe]) is a building material made from earth and other organic materials. Adobe means mudbrick in Spanish, but in some English-speaking regions of Spanish heritage, the term is used to refer to any kind of earth construction. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world.
