Colombia During World War II
The history of Colombia during World War II began in 1939. Although geographically distant from the main theaters of war, Colombia played an important role in World War II because of its strategic location near the Panama Canal, and its access to both the Atlantic and Pacific Oceans. Colombia also experienced major changes to its military and society, due to increased influence from the United States, but it was also able to maintain its sovereignty throughout the war, as well as avoid sending troops into battle. Colombia ceased diplomatic relations with the Axis powers in December 1941, following the Japanese attack on Pearl Harbor, it allowed the U.S. to station troops in the country and finally entered the war on the Allies' side on November 26, 1943, after a series of German U-boat attacks on Colombian ships. Despite the declaration, Colombia did not send an army overseas, but its navy was active in countering U-boat operations in the Caribbean. History Economics The ...

Rayon
Rayon is a semi-synthetic fiber, made from natural sources of regenerated cellulose, such as wood and related agricultural products. It has the same molecular structure as cellulose. It is also called viscose. Many types and grades of viscose fibers and films exist. Some imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen. The types that resemble silk are often called artificial silk. The fibre is used to make textiles for clothing and other purposes. Rayon production involves solubilizing cellulose to allow turning the fibers into required form. Three common ways to solubilize are the cuprammonium process, not in use today, using ammoniacal solutions of copper salts; the viscose process, the most common today, using alkali and carbon sulfide; and the Lyocell process, using amine oxide. The last avoids the neurotoxic carbon sulfide of the viscose process but is also more expensive. Rayon and its variants Rayon is produced by dissolving c ...

Colony
In modern parlance, a colony is a territory subject to a form of foreign rule. Though dominated by the foreign colonizers, colonies remain separate from the administration of the original country of the colonizers, the '' metropolitan state'' (or "mother country"). This administrative colonial separation makes colonies neither incorporated territories nor client states. Some colonies have been organized either as dependent territories that are not sufficiently self-governed, or as self-governed colonies controlled by colonial settlers. The term colony originates from the ancient Roman '' colonia'', a type of Roman settlement. Derived from ''colon-us'' (farmer, cultivator, planter, or settler), it carries with it the sense of 'farm' and 'landed estate'. Furthermore the term was used to refer to the older Greek ''apoikia'' (), which were overseas settlements by ancient Greek city-states. The city that founded such a settlement became known as its ''metropolis'' ("mother-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black Market
A black market, underground economy, or shadow economy is a clandestine market or series of transactions that has some aspect of illegality or is characterized by noncompliance with an institutional set of rules. If the rule defines the set of goods and services whose production and distribution is prohibited by law, non-compliance with the rule constitutes a black market trade since the transaction itself is illegal. Parties engaging in the production or distribution of prohibited goods and services are members of the . Examples include the illegal drug trade, prostitution (where prohibited), illegal currency transactions, and human trafficking. Violations of the tax code involving income tax evasion in the . Because tax evasion or participation in a black market activity is illegal, participants attempt to hide their behavior from the government or regulatory authority. Cash is the preferred medium of exchange in illegal transactions since cash transactions are less- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreign Economic Administration
In the administration of Franklin Delano Roosevelt, the Foreign Economic Administration (FEA) was formed to relieve friction between US agencies operating abroad on September 25, 1943. As described by the biographer of the FEA's chief, Leo Crowley, the agency was designed and run by "The Nation's #1 Pinch-hitter". S. L. Weiss Stuart L. Weiss (1996) ''The President's Man: Leo Crowley and Franklin Roosevelt in Peace and War'', Southern Illinois University Press describes Crowley's management style as follows: "Based on his own success in Washington, he had concluded that sound administration meant clearly demarcating lines of authority between agencies and, within each, finding the right staff and giving it only the most basic guidance and coordination". Weiss' evidence for Crowley's design is a memo Crowley sent to James Byrnes on September 21, 1943, of "his assessment of the conflict and confusion among the economic agencies operating abroad. His lengthy memorandum argued that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconstruction Finance Corporation
The Reconstruction Finance Corporation was a government corporation administered by the United States Federal Government between 1932 and 1957 that provided financial support to state and local governments and made loans to banks, railroads, mortgage associations, and other businesses. Its purpose was to boost the country's confidence and help banks resume daily functions after the start of the Great Depression. The RFC became more prominent under the New Deal and continued to operate through World War II. It was disbanded in 1957, when the US Federal Government concluded that it no longer needed to stimulate lending. The RFC was an independent agency of the US Federal Government, and fully owned and operated by the government. The idea was suggested by Eugene Meyer of the Federal Reserve Board of Governors, recommended by President Herbert Hoover, and established by Congress in 1932. It was modeled after the US War Finance Corporation of World War I. In total, it gave US$2 bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platinum
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish , a diminutive of "silver". Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for ~80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Conse ...

Office Of Price Administration
The Office of Price Administration (OPA) was established within the Office for Emergency Management of the United States government by Executive Order 8875 on August 28, 1941. The functions of the OPA were originally to control money (price controls) and rents after the outbreak of World War II. History President Franklin D. Roosevelt inaugurated the Council of National Defense Advisory Commission on May 29, 1940, to include Price Stabilization and Consumer Protection Divisions. Both divisions merged to become the Office of Price Administration and Civilian Supply (OPACS) within the Office for Emergency Management by Executive Order 8734, on April 11, 1941. Civil supply functions were transferred to the Office of Production Management.Herman, Arthur.

Coffee
Coffee is a drink prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It is the most popular hot drink in the world. Seeds of the '' Coffea'' plant's fruits are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often used to mask the bitter taste or enhance the flavor. Though coffee is now a global commodity, it has a long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee drinking in the form of the modern b ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members 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 cr ...
