Energy generation in stars
In the early twentieth century science was wondering what was the source of the incredible energy that fed the stars. None of the known solutions in feasible time. No chemical reaction yields necessary to keep off the sun light that also the gravitational contraction, although it was a source of energy, could not explain the contribution of heat over billions of years. Sir Arthur Eddington first suggested in the 1920s that the contribution of energy came from nuclear reactions. There are two types of nuclear reactions, the fission and fusion. The fission reactions can not maintain the brightness of a star due to its relatively low energy efficiency and, especially, require that elements heavier than iron, which are not abundant in the universe. The first detailed mechanism of nuclear fusion reactions are capable of maintaining the internal structure of a star was discovered by Hans Bethe in 1938, is valid for stars of intermediate or high mass and is named after its discoverer (or Bethe cycle CNO cycle) .
Yet, it appears that the temperatures are reached in the cores of stars are too low to merge ions. An erection is nothing but resulting effect of buy sildenafil without prescription sufficient blood circulation. When a curse cheap cialis 100mg is not properly treated, it grows to infect all parts of the mind, body, and spirit can lead to an idea relationship. Dangers of Misusing Erectile Dysfunction Medicine The medications show some known risks that lowest viagra price all men need to know about. This legislation means that in the future, it will discount online viagra continue to be in the future, and you will die before it manifests. It happens that the tunnel effect that allows two particles to energies sufficient to pass the potential barrier that separates them have a chance to jump the barrier and be able to join. There are lots of green energy suppliers to choose from in New York like and other renewable energy suppliers. Having so many collisions, are statistically sufficient for fusion reactions to be the star but do not hold as many reactions as to make it explode. There is an optimal energy for which they are most reactions resulting from the crossing of the probability that two particles having a certain energy E at temperature T and the probability that these particles will jump the barrier by tunnel effect. It’s called the Gamow peak.
A variety of different fusion reactions take place inside the cores of stars, which depend on the mass and composition.
Normally, the stars begin burning their nuclear about 75 hydrogen and 25 helium with small traces of other elements. At the core of the Sun with about 107 K the hydrogen is fused into helium through the proton-proton chain:
4A H ‘2 2e 2’e H (4.0 MeV 1.0 MeV)
2 2 H H ‘ 2 I 2’ (5.5 MeV)
He 2 ‘ 2 H 4HE (12.9 MeV)
These reactions are reduced in the overall reaction:
4A H ‘4HE 2e 2’ 2’e (26.7 MeV)
In more massive helium stars are produced in a cycle of reactions catalyzed by carbon, or CNO cycle is the cycle Bethe. This is represented in the exemplary case of a star with 18 solar masses:
The stars whose nuclei are at 108 K and whose masses range from 0.5 to 10 solar masses of helium resulting from the initial reactions can be transformed into carbon through the triple-alpha process:
4HE 4HE 92 keV ‘Be 8
Be 4HE 8 keV 67 ’12 C
12 C ’12C’ 7.4 MeV
The overall reaction is:
34He ’12C’ 7.2 MeV

Sterling area
The sterling area: the area sterling current (2007) came out after 1972 (Ireland only) was released in 1972 came out before 1972
Sterling area sterling area or refers to a group of countries, often former dominions and colonies of the British Empire (and the British Commonwealth of Nations) that use the pound sterling as its currency, or fix their currency to the British Pound Sterling to 1:1.
The area once included virtually the entire British Empire and many other countries. The rise of the United States, the economic effects of two world wars and the decline of the British Empire change the position of sterling in the world and the desire of countries to use. Currently the area includes only British territories.

Guyana’s first inhabitants were the Arawaks, the so called ( “Land of Water” in their language) to have wet lands and dense mangrove and coastal marshes. Arawks were displaced by the Caribs, who dominated much of the region and then moved to the islands of the Caribbean Sea, which took its name from them.
Arawks the Caribs and the nomads were organized into families of 15 or 20 members, and lived by hunting and fishing. Upon the arrival of Europeans in Guyana had 500 thousand inhabitants. Today about 45 thousand are originating, divided into nine ethnic groups, only seven of which maintain their identity and their culture.
Fueled by the legend of El Dorado, the Dutch created in the year 1616 the first fort of Guyana, which then consisted of three colonies: Demerara, Berbice and Essequibo. In 1796, the Dutch colony was taken by the British, they had begun a massive introduction of slaves. In 1763, the African Cuffy (now the national hero), he spearheaded a rebellion that was bloodily suppressed.
Slaves fleeing plantations were to live in the forests with the Indians. The racial and cultural mix led to the so-called Maroons. These groups joined the Chinese, Javanese and Indians, brought by the British as cheap labor. Succeeded in the ideals of independence since 1950 with the People’s Progressive Party (PPP), a program of national independence and social improvements, and long-term social transformation of society. It was conducted by Cheddi Jagan for three successive periods to the post of prime minister (1953-1961).
After years of violent street, United Kingdom recognized the independence of Guyana on May 26, 1966 in the Commonwealth. By this time the PPP was split: most of the Afro-Guyanese had been nucleated at the National People’s Congress (NPC), while the indus-asian remained faithful to Jagan. Forbes Burnham, leader of the NPC, assumed the government, supported by other ethnic minorities.
Ethnic conflict and U.S. interests have influenced the division of the PPP. United States saw the Guyanese independence and socialism Jagan of a threat to their hegemony in the Caribbean.
Burnham came to government with the blessing of Washington, but his politics are not dependent on the U.S. Ruled by non-alignment in 1970 and proclaimed the Republica Cooperativa.

Cheddi Jagan in 1976 to proclaim the need to “achieve an anti-national unity imperialista ” in moments of tension bordering on Brazil. Representatives of the PPP returned to parliament, which had withdrawn in protest against electoral fraud. Then Burnham announced the creation of a popular militia to defend the revolution.
The elections were postponed for a referendum that gave the parliament the drafting of a constitution, the reason for the withdrawal of the PPP of legislative activities for the second time. In 1980, Burnham was elected president. according to international observers, these elections were fraudulent. That year Burnham request assistance from the IMF and allow corporations to exploit the oil and uranium.
In 1980, Walter Rodney, the founder of the Working People’s Alliance (WPA), was killed by a bomb exploded in his car. Never identified those responsible.
Venezuela rekindled their dispute with Guyana. Caracas claims the Essequibo region (about 159 thousand KMA , three-quarters of the territory Guyana), arguing that these lands were illegally seized by British imperialism in the nineteenth century. In 1983 the two countries turned to the United Nations. In 1985 he resumed talks to resolve the dispute. The negotiations revolved around the possibility that Venezuela obtain an outlet to the Atlantic.
In 1984, with increasing financial difficulties and the crisis with unions, Burnham manage with an IMF loan of 150 million. IMF conditions were unacceptable according to Burnham. The U.S. invasion of Grenada Guyana and the condemnation of this action, worsened relations between the two countries. Guyana looking closer to the socialist countries.
Burnham died in 1985 and was replaced by Desmond Hoyte. The PNC won the general elections of that year, but the opposition denounced alleged fraud. In 1986, five of the six opposition parties formed the Patriotic Coalition for Democracy and won all the seats.

Regional elections in Colombia, 2007
(Redirected from regional elections in Colombia (2007))
On October 28, 2007 elections were held in Colombia in order to choose the posts of governors for the 32 departments, Members of the departmental assemblies, mayors of municipalities 1099, local officials and elected representatives of local administrative boards.
The preparation of the elections and the electoral campaign was conducted amid a heated debate about the lack of safeguards for voters, in part by the intervention there were fears of illegal armed groups such as self-defense or paramilitary groups and guerrilla groups, there were fears not only to sabotage the elections, but support a candidate as has happened in the past ended up being where several politicians elected with the support of members of the AUC in the scandal known as parapolitics. There is also fear of possible penetration of drug money in campaigns, a situation that has been experienced in past opportunities and at times has been collusion in the action of illegal armed groups. Fraud also often offered through the practice known as “buying votes and moved.” In this regard, the Attorney General Edgardo Maya Villazon expressly considered that the elections should be conducted under the current system and that the electoral system, which predates the 1991 Constitution is outdated and is perfect for this type of fraud. Despite these drawbacks the elections were conducted. On September 18, before the elections had been reported killed in the 56 candidate countries, others have suffered attacks and some were abducted, beaten and many were threatened. The figure continued to rise in subsequent days.

Chapter I: Ilusion, unlimited hope and optimism
As the main antecedent of the stock crisis, Galbraith’s spectacular development located in the housing market in Florida (USA), especially after 1925. Thus, Galbraith mentions the participation of Carlo Ponzi, known creator of the scheme that bears his name (a type of pyramid scam economica) on sale of land near Jacksonville (Florida).
Galbraith extends this overview to the field full of stock speculators, backed by successive records in terms of Wall Street stock indices (for which use the index of The New York Times on 25 industrial values, rather than the more usual Dow Jones) and of shares traded on the market (in 1928: 3.9 million shares on March 9 5.1 million on June 12 6.6 million November 16).
The author also highlights another important factor as the unbalanced use of the trading period with a guarantee, by which an investor can apply for a bank loan to purchase shares in the bag, depositing as collateral the shares acquired. These credits are subject to an interest of between 5 and 12 percent (much lower than usual in the bag upgradings in those years). This not only caused many Americans made to speculate on the stock exchange, but carries many savers (both individuals and companies, domestic and foreign) to offer their savings to banks on Wall Street with the sole purpose of financing the speculation.

Investment Banking
Investment banking or banking business that is specialized in obtaining, for private companies and governments, the money or the financial instruments needed to make certain investments, through the issuance and sale of securities in the capital markets.
Most banks offer investment advisory services for mergers, acquisitions and divisions and other financial services to customers such as trade or placement of future income, debts, stocks or commodities.
Generally countries require special licenses for investment banks and can not operate simultaneously as commercial banks, namely deposits.
Mutual funds, hedge funds and pension funds, whose objective is to maximize return on investment through the savings of the “buy side” of the securities issued and sold by investment banks. In some countries, firms operating both in the purchase and sale.
