Cerros Colorados Res
Cerros is an Eastern Lowland Maya civilization, Maya archaeological site in northern Belize that functioned from the Late Preclassic to the Postclassic period. The site reached its apogee during the Mesoamerican Mesoamerican chronology, Late Preclassic and at its peak, it held a population of approximately 1,089 people. The site is strategically located on a peninsula at the mouth of the New River (Belize), New River where it empties into Chetumal Bay on the Caribbean coast. As such, the site had access to and served as an intermediary link between the coastal trade route that circumnavigated the Yucatán Peninsula and inland communities. The inhabitants of Cerros constructed an extensive canal system and utilized raised field, raised-field agriculture. Site organization The core of the site immediately abuts the bay and consists of several relatively large structures and Mesoamerican pyramids, stepped pyramids, an acropolis complex, and two Mesoamerican ballgame, ballcourts.

Geography Of Neuquén Province
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Power In Argentina
The electricity sector in Argentina constitutes the third largest power market in Latin America. It relies mostly on thermal generation (60% of installed capacity) and hydropower generation (36%). The prevailing natural gas-fired thermal generation is at risk due to the uncertainty about future gas supply. Faced with rising electricity demand (over 6% annually) and declining reserve margins, the government of Argentina is in the process of commissioning large projects, both in the generation and transmission sectors. To keep up with rising demand, it is estimated that about 1,000 MW of new generation capacity are needed each year. An important number of these projects are being financed by the government through trust funds, while independent private initiative is still limited as it has not fully recovered yet from the effects of the 2002 Argentine economic crisis. The electricity sector was unbundled in generation, transmission and distribution by the reforms carried o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Limay River
The Limay River is an important river in the northwestern Argentine Patagonia (the region of Comahue). It originates at the eastern end of the Nahuel Huapi Lake and flows in a meandering path for about , collecting the waters of several tributaries, such as the Traful River, the Pichileufú and the Collón Curá. It then meets the Neuquén River and together they become the Río Negro. At this confluence lies the city of Neuquén. The river serves as natural border between the provinces of Río Negro and Neuquén. Its deep waters are clear, and carry a large flow, on average. Its drainage basin has an area of and includes almost all the rivers and streams of the Atlantic basin in the region, as well as an extensive network of lakes. The waters of the Limay are used to generate hydroelectricity at the five dams built on its course: Alicurá, Piedra del Águila, Pichi Picún Leufú, El Chocón, and Arroyito; together with the Cerros Colorados Complex on the Neuquén River ...

El Chocón Dam
The El Chocón Dam ( es, Represa El Chocón) is the fourth of the five dams on the Limay River in the northwestern Argentine Patagonia (the Comahue region), at above mean sea level. El Chocón is on the Limay River at about upstream of its confluence with the Neuquén River. El Chocón is used to regulate the flow of the Limay River, for irrigation, and for the generation of hydroelectricity. Its power station is the largest hydroelectric power plant in Patagonia, with a capacity of . It was built by the state-owned company Hidronor (Hidroeléctrica Norpatagónica). It started operating in 1973, and achieved full capacity in 1978. In the period 1974–1995 it produced an annual average of . In 1993 it was privatized, with an exploitation concession granted to Hidroeléctrica El Chocón S. A.
