Somaliland Shilling
The Somaliland shilling (, ; abbreviation: Sl.Sh. or SLSH; symbol: Slash (punctuation), /-) is the official currency of the Republic of Somaliland, an List of states with limited recognition, unrecognised state in the Horn of Africa, recognised internationally as ''de jure'' part of Somalia. Overview The shilling has been the currency of parts of Somalia since 1921, when the East African shilling was introduced to the former British Somaliland protectorate. Following the 1960 independence and unification of the former territories of British Somaliland and Italian Somaliland, their respective currencies, the East African shilling and somalo (which were equal in value) were replaced at par in 1962 by the Somali shilling. Names used for its denominations were cent (singular: centesimo; plural: centesimi) and سنت (plural: سنتيمات), along with shilling (singular: scellino; plural: scellini) and شلن. In September 1994, the Parliament of Somaliland endorsed President Muha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Dollar
The United States dollar (Currency symbol, symbol: Dollar sign, $; ISO 4217, currency code: USD) is the official currency of the United States and International use of the U.S. dollar, several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish dollar, Spanish silver dollar, divided it into 100 cent (currency), cents, and authorized the Mint (facility), minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The U.S. dollar was originally defined under a bimetallism, bimetallic standard of (0.7734375 troy ounces) fine silver or, from Coinage Act of 1834, 1834, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fixed Exchange Rate System
A fixed exchange rate, often called a pegged exchange rate, is a type of exchange rate regime in which a currency's value is fixed or pegged by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold or silver. There are benefits and risks to using a fixed exchange rate system. A fixed exchange rate is typically used to stabilize the exchange rate of a currency by directly fixing its value in a predetermined ratio to a different, more stable, or more internationally prevalent currency (or currencies) to which the currency is pegged. In doing so, the exchange rate between the currency and its peg does not change based on market conditions, unlike in a floating (flexible) exchange regime. This makes trade and investments between the two currency areas easier and more predictable and is especially useful for small economies that borrow primarily in foreign currency and in which external trade forms a large ...

Somali Pigeon
The Somali pigeon (''Columba oliviae'') or Somali stock dove is a species of bird in the family Columbidae. It is endemic to Somalia. Because there has hardly been any research on the species, the health of the population is uncertain; however, it is believed that the species is relatively rare. The IUCN Redlist identified a possible threat to the species from the speckled pigeon (''Columba guinea''). ''C. oliviae'' is found mostly on the ground, where it often forages, most frequently in rock along arid coasts. Taxonomy The Somali pigeon is placed in the ''Oenas'' sub-group within the genus ''Columba'' alongside the stock dove and yellow-eyed pigeon, based on their similar mauve heads and wing markings, but believed to be more closely related to the latter overall. Description ''C. oliviae'' is a mid-sized pigeon with pale grey coloration, a mauve cap, yellow eyes and an iridescent collar with bronze-green tones. It has a bluish-gray rump, dark wing edges and dark bands along i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stainless Steel
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromium content of 11% or more, which forms a Passivation (chemistry), passive film that protects the material and can self-healing material, self-heal when exposed to oxygen. It can be further alloyed with elements like molybdenum, carbon, nickel and nitrogen to enhance specific properties for various applications. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for ch ...

Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. 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+ ...

Italian Greyhound
The Italian Greyhound or Italian Sighthound () is an Italian dog breed, breed of small sighthound. It was bred to hunt European hare, hare and European rabbit, rabbit, but is kept mostly as a companion dog. History Small dogs of sighthound type have long been popular with nobility and Royal family, royalty. Among those believed to have kept them are Frederick II, Duke of Swabia; members of the D'Este, Medici and Visconti of Milan, Visconti families; the French kings Louis XI, Charles VIII of France, Charles VIII, Charles IX of France, Charles IX, Louis XIII and Louis XIV; Frederick II of Prussia, Frederick the Great of Prussia; Anne of Denmark; Catherine II of Russia, Catherine the Great; and Queen Victoria. Dogs of this type have often been represented in sculpture – including a second-century Roman statue now in the Vatican Museums – and paintings, notably by Giotto, Sassetta and Tiepolo. Dogs of this kind were taken in the first half of the nineteenth century to the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vervet Monkey
The vervet monkey (''Chlorocebus pygerythrus''), or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus '' Chlorocebus''. The five distinct subspecies can be found mostly throughout Southern Africa, as well as some of the eastern countries. These mostly herbivorous monkeys have black faces and grey body hair color, ranging in body length from about for females, to about for males. In addition to behavioral research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviors of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use. Vervets live in social groups ranging from 10 to 70 individuals, with males moving to other groups at the time of sexual maturity. Studies done on vervet monkeys involve their communication and alarm cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockerel
The chicken (''Gallus gallus domesticus'') is a domesticated subspecies of the red junglefowl (''Gallus gallus''), originally native to Southeast Asia. It was first domesticated around 8,000 years ago and is now one of the most common and widespread domesticated animals in the world. Chickens are primarily kept for their meat and eggs, though they are also kept as pets. As of 2023, the global chicken population exceeds 26.5 billion, with more than 50 billion birds produced annually for consumption. Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. A hen bred for laying can produce over 300 eggs per year. Chickens are social animals with complex vocalizations and behaviors, and feature prominently in folklore, religion, and literature across many societies. Their economic importance makes them a central component of global animal husbandry and agriculture. Nomenclature Terms for chickens include: * ''Bid ...

Richard Francis Burton
Captain (British Army and Royal Marines), Captain Sir Richard Francis Burton, Order of St Michael and St George, KCMG, Royal Geographical Society#Fellowship, FRGS, (19 March 1821 – 20 October 1890) was a British explorer, army officer, orientalist writer and scholar. He was famed for his travels and explorations in Asia, Africa and South America, as well as his extensive knowledge of languages and cultures, speaking up to 29 different languages. Born in Torquay, Devon, Burton joined the Bombay Army as an officer in 1842, beginning an eighteen-year military career which included a brief stint in the Crimean War. He was subsequently engaged by the Royal Geographical Society (RGS) to explore the East African coast, where Burton along with John Hanning Speke led an expedition to discover the source of the Nile and became the first European known to have seen Lake Tanganyika. He later served as the British consul (representative), consul in Bioko, Fernando Pó, Santos, São Paulo, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mint Mark
A mint mark is a letter, symbol or an inscription on a coin indicating the mint where the coin was produced. It is distinct from a mintmaster mark, the mark of the mintmaster. History Mint marks were first developed to locate a problem. If a coin was underweight, or overweight, the mint mark would immediately tell where the coin was minted, and the problem could be located and fixed. Another problem which could occur would be a dishonest mint official debasing the coin, or putting less precious metal in the coin than specified. The first mint marks, called "Magistrate Marks" were developed by the Greeks, and named the Magistrate in charge of producing that coin. Debasing a coin, or otherwise tampering with it, was a very serious crime, often punishable by death in many civilizations. For example, in 1649, the directors of the Spanish colonial American Mint at Potosí, in what is today Bolivia, were condemned to death for seriously debasing the coinage. The initials of the ass ...
