Gibeon (Namibia)
Gibeon ( Nama: Khaxa-tsûs) is a village in Gibeon Constituency in the Hardap Region of Namibia. History Gibeon, originally known by the name Khaxa-tsûs, received its name from Kido Witbooi, first Kaptein of the ǀKhowesin, a subtribe of the Orlam. He arrived with his followers in about 1850, shortly after a Rhenish mission station was established here. Gibeon has been the home town of this group, subsequently also known as the ''Witbooi Nama'', ever since. Buildings and structures Gibeon Railway Station is located in the village. The station is a stop on the TransNamib Railway. It is also home to a public sports stadium. The stadium was built in 1986 and fell into disrepair by 1993. In 2003, the Ministry of Sport of Namibia budgeted N$ 450,000 for repairs and awarded part of the public tender to Namibia Renovations, but the company disappeared days after winning the tender and their whereabouts could not be confirmed. As of December 2007, none of the repairs have been co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regions Of Namibia
Namibia uses regions as its first-level subnational administrative divisions. Since 2013, it has 14 regions which in turn are subdivided into 121 constituencies. Upon Namibian independence, the pre-existing subdivisions from the South African administration were taken over. Since then, demarcations and numbers of regions and constituencies of Namibia are tabled by delimitation commissions and accepted or declined by the National Assembly. In 1992, the ''1st Delimitation Commission'', chaired by Judge President Johan Strydom, proposed that Namibia should be divided into 13 regions. The suggestion was approved in the lower house, The National Assembly. In 2014, the ''4th Delimitation Commission'' amended the number of regions to fourteen. Regions 1990–1992 See also *Constituencies of Namibia Each of the 14 regions of Namibia is further subdivided into electoral constituencies. The size of the constituencies varies with the size and population of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Tender
Government procurement or public procurement is the procurement of goods, services and works on behalf of a public authority, such as a government agency. Amounting to 12 percent of global GDP in 2018, government procurement accounts for a substantial part of the global economy. To prevent fraud, waste, corruption, or local protectionism, the laws of most countries regulate government procurement to some extent. Laws usually require the procuring authority to issue public tenders if the value of the procurement exceeds a certain threshold. Government procurement is also the subject of the Agreement on Government Procurement (GPA), a plurilateral international treaty under the auspices of the WTO. Overview Need for government procurement Government procurement is necessary because governments cannot produce all the inputs for the goods they provide themselves. Governments usually provide public goods, e.g. national defense or public infrastructure. Public goods are non-riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namibian Local And Regional Elections, 2015
Namibia held elections for their local and regional councils on 27 November 2015. Ballots were cast using electronic voting. Electoral system Elections to regional councils are held using the first-past-the-post electoral system. Voters in each constituency elect one councillor to represent them on their regional council. Local authority councillors are elected by a system of proportional representation. Results Regional and local elections taken together elected 199 woman out of the 499 available seats, partly because affirmative action for women is required by law in local authority elections. Regional elections There are 121 constituency councillors to be elected. In twenty-eight of them SWAPO was announced as winner in October because no opposition party nominated a candidate. Local election Local elections determine the population of the village, town, and city councils and have a direct influence on who will become mayor, as this position is elected among all councillor ...

Widmanstätten Pattern
Widmanstätten patterns, also known as Thomson structures, are figures of long nickel–iron crystals, found in the octahedrite iron meteorites and some pallasites. They consist of a fine interleaving of kamacite and taenite bands or ribbons called ''lamellae''. Commonly, in gaps between the lamellae, a fine-grained mixture of kamacite and taenite called plessite can be found. Widmanstätten patterns describe features in modern steels, titanium, and zirconium alloys. Discovery In 1808, these figures were observed by Count Alois von Beckh Widmanstätten, the director of the Imperial Porcelain works in Vienna. While flame heating iron meteorites, Widmanstätten noticed color and luster zone differentiation as the various iron alloys oxidized at different rates. He did not publish his findings, claiming them only via oral communication with his colleagues. The discovery was acknowledged by Carl von Schreibers, director of the Vienna Mineral and Zoology Cabinet, who named the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octahedrite
Octahedrites are the most common structural class of iron meteorites. The structures occur because the meteoric iron has a certain nickel concentration that leads to the exsolution of kamacite out of taenite while cooling. Structure Octahedrites derive their name from the crystal structure paralleling an octahedron. Opposite faces are parallel so, although an octahedron has 8 faces, there are only 4 sets of kamacite plates. Due to a long cooling time in the interior of the parent asteroids, these alloys have crystallized into intermixed millimeter-sized bands (from about 0.2 mm to 5 cm). When polished and acid etched the classic Widmanstätten patterns of intersecting lines of lamellar kamacite, are visible. In gaps between the kamacite and taenite lamellae, a fine-grained mixture called plessite is often found. An iron nickel phosphide, schreibersite, is present in most nickel-iron meteorites, as well as an iron-nickel-cobalt carbide, cohenite. Graphite and troili ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...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] |
Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Meteorite
Iron meteorites, also known as siderites, or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, with the exception of the IIE iron meteorite group The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, due to the malleability and ductility of the meteoric iron, before the development of smelting that signaled the beginning of the Iron Age. Occurrence Although they are fairly rare compared to the stony meteorites, comprising only about 5.7% of witnessed falls, iron meteorites have historically been heavily over-represented in meteorite collections. This is due to several factors: * They are easily recognized as unusual even by laymen, as opposed to stony meteorites. Modern-day searches for meteorites in deserts and Antarctica yield a muc ...
