Ugandan Shilling
The shilling ( sw, shilingi; abbreviation: USh; ISO code: UGX) is the currency of Uganda. Officially divided into cents until 2013, due to substantial inflation the shilling now has no subdivision. Notation Prices in the Ugandan shilling are written in the form of , where x is the amount in shillings, while y is the amount in cents. An equals sign or hyphen represents zero amount. For example, 50 cents is written as "" and 100 shillings as "" or "100/-". Sometimes the abbreviation ''USh'' is prefixed for distinction. If the amount is written using words as well as numerals, only the prefix is used (e.g. USh 10 million). This pattern was modelled on sterling's pre-decimal notation, in which amounts were written in some combination of pounds (£), shillings (s), and pence (d, for denarius). In that notation, amounts under a pound were notated only in shillings and pence. History The first Ugandan shilling (UGS) replaced the East African shilling in 1966 at p ...

East African Florin
The Florin was the currency of the British colonies and protectorates of East Africa between 1920 and 1921. It was divided into 100 cents. It replaced the East African rupee at par, and was replaced in turn by the East African shilling at a rate of 2 shillings = 1 florin. The florin was equivalent to 2 shillings sterling. Coins Because of its short period in existence, few of the coin A coin is a small, flat (usually depending on the country or value), round piece of metal or plastic used primarily as a medium of exchange or legal tender.

Coins were minted in denominations of 1, 5, 10, 25 and 50 cents and 1 florin but, according to the "Standard Catalog of World Coins" (C. L. Krause & C. Mishler, Krause Publications), the 50 cents coins were not released for circulation and only 30% of the 1, 5 and 10 cent coins produced ...

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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East African Crowned Crane
The grey crowned crane (''Balearica regulorum''), also known as the African crowned crane, golden crested crane, golden crowned crane, East African crane, East African crowned crane, African crane, Eastern crowned crane, Kavirondo crane, South African crane and crested crane, is a bird in the crane family, Gruidae. It is found in eastern and southern Africa, and is the national bird of Uganda. Taxonomy The grey crowned crane is closely related to the black crowned crane, and the two species have sometimes been treated as the same species. The two are separable on the basis of genetic evidence, calls, plumage and bare parts, and all authorities treat them as different species today. There are two subspecies. The East African ''B. r. gibbericeps'' (crested crane) occurs in the east of the Democratic Republic of the Congo and in Uganda, of which it is the national bird represented in its national flag, and Kenya to eastern South Africa. It has a larger area of bare red facial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towa ...

Nile Perch
The Nile perch (''Lates niloticus''), also known as the African snook, Goliath perch, African barramundi , Goliath barramundi, Giant lates or the Victoria perch, is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of the Afrotropical realm, being native to the Congo, Nile, Senegal, Niger and Lake Chad, Volta, Lake Turkana, and other river basins. It also occurs in the brackish waters of Lake Maryut in Egypt. The Nile perch is a fish of substantial economic and food-security importance in East Africa. Originally described as ''Labrus niloticus,'' among the marine wrasses, the species has also been referred to as ''Centropomus niloticus''. Common names include African snook, Victoria perch (a misleading trade name, as the species is not native to Lake Victoria, though they have been introduced there), and many local names in various African languages, such as the Luo name ''mbuta'' or ''mputa''. In Tanzania, it is called '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper-nickel
Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel.) Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical, petrochemical, and electrical industries. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy has 3:1 copper to nickel ratio, with very small amounts of manganese. In the past, true silver coins were debased with cupronickel, such as coins of the pound sterling from 1947 onward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankole-Watusi
The Ankole-Watusi is a modern American breed of domestic cattle. It derives from the Ankole group of Sanga cattle breeds of east and central Africa. It is characterized by very large horns. History The Ankole-Watusi derives from cattle of the Ankole group of Sanga cattle breeds of east and central Africa. Some of these were brought to Germany as zoo specimens in the early twentieth century, and from there spread to other European zoos. Some were imported to the United States, and in 1960 a herd was started in New York State by cross-breeding some of them with an unrelated Canadian bull. A breed society, the Ankole Watusi International Registry, was set up in 1983, and in 1989 a breed standard was drawn up. In 2016 the total number for the breed was thought to be approximately 1500 head, some 80% of them in the United States. Characteristics The Ankole-Watusi may be a number of different colors, but is usually red. The horns are unusually large, with a wide spread an ...
