Temple Of The Feathered Serpent, Teotihuacan
The Temple of the Feathered Serpent is the third largest pyramid at Teotihuacan, a Pre-Columbian Mexico, pre-Columbian site in central Mexico (the term ''Teotihuacan'', or ''Teotihuacano'', is also used for the whole civilization and cultural complex associated with the site). This structure is notable partly due to the discovery in the 1980s of more than a hundred possibly sacrificial victims found buried beneath the structure. The burials, like the structure, are dated to between 150 and 200 CE. The pyramid takes its name from representations of the Mesoamerican "feathered serpent" deity which covered its sides. These are some of the earliest-known representations of the feathered serpent, often identified with the much-later Aztec god Quetzalcoatl. "Temple of the Feathered Serpent" is the modern-day name for the structure; it is also known as the Temple of Quetzalcoatl and the Feathered Serpent Pyramid. Location The Temple of the Feathered Serpent is located at the southern e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Teotihuacán - Modell Ciudadela
Teotihuacan (Spanish: ''Teotihuacán'') (; ) is an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, which is located in the State of Mexico, northeast of modern-day Mexico City. Teotihuacan is known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas, namely Pyramid of the Sun and Pyramid of the Moon. At its zenith, perhaps in the first half of the first millennium (1 CE to 500 CE), Teotihuacan was the largest city in the Americas, with a population estimated at 125,000 or more, making it at least the sixth-largest city in the world during its epoch. The city covered eight square miles (21 km2), and 80 to 90 percent of the total population of the valley resided in Teotihuacan. Apart from the pyramids, Teotihuacan is also anthropologically significant for its complex, multi-family residential compounds, the Avenue of the Dead, and its vibrant, well-preserved murals.

American Express
American Express Company (Amex) is an American multinational corporation specialized in payment card services headquartered at 200 Vesey Street in the Battery Park City neighborhood of Lower Manhattan in New York City. The company was founded in 1850 and is one of the 30 components of the Dow Jones Industrial Average. The company's logo, adopted in 1958, is a gladiator or centurion whose image appears on the company's well-known traveler's cheques, charge cards, and credit cards. During the 1980s, Amex invested in the brokerage industry, acquiring what became, in increments, Shearson Lehman Hutton and then divesting these into what became Smith Barney Shearson (owned by Primerica) and a revived Lehman Brothers. By 2008 neither the Shearson nor the Lehman name existed. In 2016, credit cards using the American Express network accounted for 22.9% of the total dollar volume of credit card transactions in the United States. , the company had 121.7million cards in force, includ ...

Instituto Nacional De Antropología E Historia
The Instituto Nacional de Antropología e Historia (INAH, ''National Institute of Anthropology and History'') is a Mexican federal government bureau established in 1939 to guarantee the research, preservation, protection, and promotion of the prehistoric, archaeological, anthropological, historical, and paleontological heritage of Mexico. Its creation has played a key role in preserving the Mexican cultural heritage. Its current national headquarters are housed in the Palace of the Marqués del Apartado. INAH and the Instituto Nacional de Bellas Artes y Literatura are tasked with cataloging and protecting monuments and buildings regarded as cultural patrimony. INAH is entrusted with 'archaeological' (pre-Hispanic and paleontological) and 'historical' (post-Conquest 16th to 19th centuries) structures, zones and remnants, while INBAL is entrusted with 'artistic' buildings and monuments (properties that are of significant aesthetic value as deemed by a commission).

World Monuments Fund
World Monuments Fund (WMF) is a private, international, non-profit organization dedicated to the preservation of historic architecture and cultural heritage sites around the world through fieldwork, advocacy, grantmaking, education, and training. Founded in 1965, WMF is headquartered in New York, and has offices and affiliates around the world, including Cambodia, France, Peru, Portugal, Spain, and the United Kingdom. In addition to hands-on management, the affiliates identify, develop, and manage projects, negotiate local partnerships, and attract local support to complement funds provided by donors. History International Fund for Monuments (1965–1984) The ''International Fund for Monuments'' (IFM) was an organization created by Colonel James A. Gray (1909–1994) after his retirement from the U.S. Army in 1960. Gray had conceived of a visionary project to arrest the settlement of the Leaning Tower of Pisa by freezing the soil underneath, and formed the organization in 196 ...

2004 World Monuments Watch
The World Monuments Watch is a flagship advocacy program of the New York-based private non-profit organization World Monuments Fund (WMF) that is dedicated to preserving the historic, artistic, and architectural heritage around the world. Selection process Every two years, it publishes a select list known as the Watch List of 100 Most Endangered Sites that is in urgent need of preservation funding and protection. It is a call to action on behalf of threatened cultural heritage monuments worldwide. The sites are nominated by governments, conservation professionals, site caretakers, non-government organizations (NGOs), concerned individuals, and others working in the field. An independent panel of international experts then select 100 candidates from these entries to be part of the Watch List, based on the significance of the sites, the urgency of the threat, and the viability of both advocacy and conservation solutions. A site’s inclusion on the Watch List attracts international ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Growth
Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism). Cell growth is not to be confused with cell division or the cell cycle, which are distinct processes that can occur alongside cell growth during the process of cell proliferation, where a cell, known as the mother cell, grows and divides to produce two daughter cells. Importantly, cell growth and cell division can also occur independently of one another. During early embryonic development ( cleavage of the zygote to form a morula and blastoderm), cell divisions occur repeatedly without cell growth. Conversely, some cells can grow without cell division or without any progression of the cell cycle, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soluble Salts
In chemistry, solubility is the ability of a chemical substance, substance, the solute, to form a solution (chemistry), solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. The extent of the solubility of a substance in a specific solvent is generally measured as the concentration of the solute in a wikt:saturated#Chemistry, saturated solution, one in which no more solute can be dissolved. At this point, the two substances are said to be at the solubility equilibrium. For some solutes and solvents, there may be no such limit, in which case the two substances are said to be "miscibility, miscible in all proportions" (or just "miscible"). The solute can be a solid, a liquid, or a gas, while the solvent is usually solid or liquid. Both may be pure substances, or may themselves be solutions. Gases are always miscible in all proportions, except in very extreme situations,J. de Swaan Arons and G. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
