Bule Hora
Bule Hora is a woreda in Oromia Region, Ethiopia. It formerly included Dugda Dawa and Kercha districts. Part of the West Guji Zone, Bule Hora was bordered on the south by the Dawa River which separates it from Arero, on the southwest by Yabelo, on the west by the Southern Nations, Nationalities, and Peoples Region and Gelana Abaya, on the northeast by Uraga, and on the east by Odo Shakiso. The largest town of Bule Hora is Bule Hora Town. In May 2000, a field assessment by the UNDP which included Bule Hora town collected informal reports of a growing number of private investors in coffee pulping/processing factories and coffee plantations in the district; however, many of their informants expressed concern voiced that this had been at the expense of local farmers. The four major crops grown in this district are maize, wheat, barley and haricot beans in that order, with some long cycle sorghum and teff as well; in some parts ensete or the false banana is also grown, which offers ...

Grain Mill
A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding. History Early history The Greek geographer Strabo reports in his ''Geography'' a water-powered grain-mill to have existed near the palace of king Mithradates VI Eupator at Cabira, Asia Minor, before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as the " Norse wheel", as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary "bed", a stone of a similar size and shape. This simple arrangement required ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments ( cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphite
Graphite () is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures it converts to diamond. It is a weak conductor of heat and electricity. Types and varieties Natural graphite The principal types of natural graphite, each occurring in different types of ore deposits, are * Crystalline small flakes of graphite (or flake graphite) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken. When broken the edges can be irregular or angular; * Amorphous graphite: very fine flake graphite is sometimes called amorphous; * Lump graphite (or vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular crystalline ...

Districts Of Ethiopia
Districts of Ethiopia, also called woredas ( am, ወረዳ; ''woreda''), are the third level of the administrative divisions of Ethiopia – after ''zones'' and the '' regional states''. These districts are further subdivided into a number of wards called ''kebele'' neighbourhood associations, which are the smallest unit of local government in Ethiopia. Overview Districts are typically collected together into zones, which form a region; districts which are not part of a zone are designated Special Districts and function as autonomous entities. Districts are governed by a council whose members are directly elected to represent each ''kebele'' in the district. There are about 670 rural districts and about 100 urban districts. Terminology varies, with some people considering the urban units to be ''woreda'', while others consider only the rural units to be ''woreda'', referring to the others as urban or city administrations. Although some districts can be traced back to earli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haricot Bean
The navy bean, haricot, pearl haricot bean, Boston bean, white pea bean, or pea bean is a variety of the common bean (''Phaseolus vulgaris'') native to the Americas, where it was first domesticated. It is a dry white bean that is smaller than many other types of white beans, and has an oval, slightly flattened shape. It features in such dishes as baked beans, various soups such as Senate bean soup, and even pies. The green bean plants that produce navy beans may be either of the bush type or vining type, depending on which cultivar they are. History The name "Navy bean" is an American term coined because the US Navy has served the beans as a staple to its sailors since the mid-1800s. In Australia, navy bean production began during World War II when it became necessary to find an economical way of supplying a nutritious food to the many troops—especially American troops—based in Queensland. The United States military maintained a large base in Kingaroy and had many bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastoralists
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastoralism, and 75% of ...
