| |  |  |  | bismuth: Encyclopedia II - New Brunswick - PoliticsNew Brunswick has a unicameral legislature consisting of 55 seats. The governing party normally is the party that wins the most seats in the provincial election. Elections are held at least every five years but may be called at any time by the Lieutenant Governor (the vice-regal representative) on consultation with the Premier of the day. The government may also fall at any time if it loses a vote of non-confidence. The Premier is the leader of the party that holds the most seats in the legislature. The current governing party is the Progressive Conservative ...

Nuclear power - Current Technology.
There are two types of nuclear power sources in current use:
The nuclear fission reactor produces heat through a controlled nuclear chain reaction in a critical mass of fissile material.
All current nuclear power plants are critical fission reactors, which are the focus of this article. The output of fission reactors is controllable. There are several subtypes of critical fission reactors. All reactors will be compared to the Pressurized Water Reactor (PWR ...

|  |  |  | bismuth: Encyclopedia II - Nuclear power - Life cycle
Main article: Nuclear fuel cycle
A Nuclear Reactor is only a small part of the life-cycle for nuclear power. The process starts with mining. Generally, uranium mines are either open-pit strip mines, or in-situ leach mines. In either case, the uranium ore is extracted, usually converted into a stable and compact form such as yellowcake, and then transported to a processing facility. At the reprocessing facility, the yellowcake is converted to uranium hexafluoride, which is then enriched using various t ...

|  |  |  | bismuth: Encyclopedia II - Charles Darwin's illness - Development of illness and symptomsDarwin was too sensitive to the sight of blood and the brutality of surgery at the time as a student of medicine at Edinburgh University, so he turned his attention to natural history, an extra-mural interest he developed further when studying to qualify as a clergyman at the University of Cambridge. He then joined the Voyage of the Beagle. During this survey expedition he suffered badly from sea-sickness during the eighteen months he was at sea, but he spent much of the 3 years 3 months he was on land in strenuous exploration. In Argentina ...

|  |  |  | bismuth: Encyclopedia II - Nuclear power - EconomyOpponents of nuclear power claim that any of the environmental benefits are outweighed by safety compromises and by the costs related to construction and operation of nuclear power plants, including costs for spent-fuel disposition and plant retirement. Proponents of nuclear power state that nuclear energy is the only power source which explicitly factors the estimated costs for waste containment and plant decommissioning into its overall cost, and that the quoted cost of fossil fuel plants is deceptively low for this reason. The cost of some renewables would be increased too if they included necessary ...

Nuclear power - Origins.
The first successful experiment with nuclear fission was conducted in 1938 in Berlin by the German physicists Otto Hahn, Lise Meitner and Fritz Strassman.
During the Second World War, a number of nations embarked on crash programs to develop nuclear energy, focusing first on the development of nuclear reactors. The first self-sustaining nuclear chain reaction was obtained by Enrico Fermi on December 2nd,1942, and reactors based on his research were used to produce the plutonium nec ...

|  |  |  | bismuth: Encyclopedia II - Charles Darwin's illness - Contribution to Darwin's workInterestingly enough, it seems that Darwin's maladies actually may have contributed a lot to what many believe was a long and fruitful creative process in science. George Pickering in his book, "Creative Malady" (1974) wrote that isolated from social life and obligations of a "normal" scientist, such as administrative and teaching work, Darwin had ample time and material comforts for researching, thinking, and writing extensively, which he did. Despite the long periods of unproductivity caused by ill health, Darwin produced much research. Da ...

|  |  |  | bismuth: Encyclopedia II - Geography of Kyrgyzstan - Topography and drainageThe mountains of Kyrgyzstan are geologically young, so that the physical terrain is marked by sharply uplifted peaks separated by deep valleys. There is also considerable glaciation. Kyrgyzstan's 6,500 distinct glaciers are estimated to hold about 650 cubic kilometers of water. Only around the Chu, Talas, and Fergana valleys is there relatively flat land suitable for large-scale agriculture.
Because the high peaks function as moisture catchers, Kyrgyzstan is relatively well watered by the streams that descend from them. None of the ri ...

|  |  |  | bismuth: Encyclopedia II - Charles Darwin's illness - ConclusionsThe exact nature of Darwin's illness or illnesses remain mysterious at this time. Unless sophisticated molecular probing of his biological remains is allowed, no definitive diagnosis can be reached. At the same time, historical investigations are probabilistic. There appears to be increasing support for the diagnosis that both organic and psychological ailments combined to cause his illness.
The issue has become embroiled in the creation-evolution controversy, with allegations that Creationists are drawing attention to interpretation of the illness to damage Darwin's reputation, and counter-allegations tha ...

Gold compounds can be aurous (univalent, +1) or auric (trivalent, +3). Gold also can under extreme conditions form a +5 state with fluorine (gold pentafluoride, AuF5), as well as (unusually for a metal), a -1 state. Such compounds containing the Au- anion are called aurides and include caesium auride, CsAu, rubidium auride, RbAu, and tetramethylammonium auride, (CH3See also: Gold, Gold - Notable characteristics, Gold - Applications, Gold - History, Gold - Value, Gold - Gold and the money supply, Gold - Restrictions on gold ownership, Gold - Return of a gold standard?, Gold - Gold in investment portfolios, Gold - Occurrence, Gold - Production, Gold - Compounds/isotopes, Gold - Precautions, Gold - Symbolism Read more here: » Gold: Encyclopedia II - Gold - Compounds/isotopes |

Ore grades of 30 g/1000 kg (30 ppm) are usually needed before gold is visible to the naked eye, therefore in most gold mines you will not see any gold. It is claimed, that all the gold that has been mined throughout the history of mankind could be incorporated in a solid ...

|  |  |  | bismuth: Encyclopedia II - Gold - OccurrenceDue to its relative chemical inertness gold is usually found as the native metal or alloy. Occasionally large accumulations of native gold (also known as nuggets) occur but usually gold occurs as minute grains. These grains occur between mineral grain boundries or as inclusions within minerals. Common gold associations are quartz often as veins and sulfide minerals. The most common sulfide associations are pyrite, chalcopyrite, galena, sphalerite, arsenopyrite, stibnite and pyrrhotite. Rarer mineral associations are petzite, calaverite, sylvanite, mut ...
