However, the environmental movement today persists in many smaller local groups, usually within ecoregions, furthering spiritual and aesthetic values which Thoreau or those who rewrote Chief Seattle's Reply would recognize. Some resemble the old U.S. conservation movement - whose modern expression is the Sierra Club, Audubon Society and National Geographic Society - American organizations with a worldwide influence. These "politically neutral" groups tend to avoid global conflicts and view the settlement of inter-human conflict ...

Many people are skeptical of the environmental movement and feel that it is more deeply rooted in politics than science. Claims made by environmentalists are often perceived as veiled attacks on industry and globalization rather than legitimate environmental concerns. Detractors are quick to note that a significant number of environmental theories and predictions have been inaccurate and suggest that the regulations recommended by environmentalists will more likely harm society rather than help nature. Specific examples include when Rachel C ...

This new idea implied a new concept of human freedom, i.e. people independently making their own lives using their own good judgement. Initially, this concept appeared rather paradoxical; thus Jean-Jacques Rousseau wrote: "People are born free, but are everywhere in chains". A big breakthrough was the French Revolution of 1789, which inspired a lot of new philosophical thought. In the philosophy of the German thinker Hegel, history is radically recast as the continual development of humanity towards ever greater freedom, continually extendin ...

CPVC is PVC (polyvinyl chloride) that has been chlorinated via a free radical chlorination reaction. This reaction is typically initiated by application of thermal or UV energy utilizing various approaches. In the process, chlorine gas is decomposed into free radical chlorine which is then reacted with PVC in a post-production step, essentially replacing a portion of the hydrogen in the PVC with chlorine. Depending on the method, a varying amount of chlorine is introduced into the polymer allowing for a measured way to fine tune the f ...

Mulroney's legacy is a complicated one, and even as of 2006 remains one heavily based on emotion. Mulroney makes the case that his once radical policies on the economy and free trade were not reversed by subsequent governments, and regards this as vindication. His Deputy Prime Minister Don Mazankowski said that his greatest accomplishment will be seen as, "Dragging Canada kicking and screaming into the 21st century." Mulroney's legacy in Canada is associated mostly with the 1988 free trade agree ...

Gastric cancer and gastric MALT lymphoma (lymphoma of the mucosa-associated lymphoid tissue) have been associated with H. pylori, and the bacterium has been categorized as a group I carcinogen by the International Agency for Research on Cancer (IARC). While the association is reasonably strong, it is not entirely clear that there is a causal relationship involved. Two related mechanisms by which H. pylori could promote cancer are under investigation. One mechanism involves the enhanced production of free radicals near See also:

Amber is heterogeneous in composition, but consists of several resinous bodies more or less soluble in alcohol, ether and chloroform, associated with an insoluble bituminous substance. Amber is a macromolecule by free radical polymerization of several precursors in the labdane family, communic acid, cummunol and biformene [1]. Labdanes are tetrameric terpenes (C20H32) and trienes which means that the organic skeleton has three alkene grou ...

In photosynthetic organisms, carotenoids play a vital role in the photosynthetic reaction centre. They either participate in the energy-transfer process, or protect the reaction center from auto-oxidation. In non-photosynthetic organisms, carotenoids have been linked to oxidation-preventing mechanisms. Carotenoids have many physiological functions. Given their structure (above) carotenoids are efficient free-radical scavengers, and they enhance the vertebrate immune system. Consequently, epidemiological studies have shown that people ...

While proposals for a much more 'inquisitive' and practical approach to the study of nature originated with Francis Bacon, Robert Boyle wrote what is considered to be a seminal work on the distinction between nature and metaphysics called A Free Enquiry into the Vulgarly Received Notion of Nature. This book, written in 1686, marked the point where the scene was set for natural philosophy to turn into science. It represented a radical departure from the scholasticism of the Middle Ages, and while features of natural philosophy retained ...

By the end of World War II, the nation was finally shrugging free of a drastic economic recession that culminated in the Great Depression. During that time, unemployment rates soared into the twenties of percent, and only radical government spending seemed to curb further degradation. The U.S. Congress, fearful of another bout of unemployment spurred by the return of discharged war veterans, sought to establish preemp ...

Selenium is a trace element in humans. It is used in free radical elimination and other antioxidant enzymes such as glutathione peroxidases and thioredoxin reductase, and also plays a role in the functioning of the thyroid gland by participating as a cofactor for thyroid hormone deiodinases [1]. Dietary selenium comes from cereals, meat, fish, and eggs. Liver and Brazil nuts are a particularly rich source of selenium. Some clinical studies have shown that se ...

Ozone, along with hypochlorite ions, is naturally produced by white blood cells and the roots of marigolds as a means of destroying foreign bodies. When ozone breaks down it gives rise to oxygen free radicals, which are highly reactive and damage or destroy most organic molecules. Ozone has a number of medical uses. It can be used to affect the body's antioxidant-prooxidant balance, since the body usually reacts to its presence by producing antioxidant enzymes. Many hospitals in the U.S. and around the world use large ozone generators ...

The compound has a peroxide group in its structure. When the peroxide comes into contact with high iron concentrations, the molecule becomes unstable and "explodes" into free radicals. This is because the oxygen atoms are highly electronegative, and the iron in the body is in the form of positively charged ions. This results in a high mechanical strain on the chemical bonds of the peroxide group. High concentrations of iron are found in red blood cells, which is also where the malaria parasites are found. When the compound enters the red blo ...

"Cracking" breaks larger molecules into smaller ones. This can be done with a thermic or catalytic method. The thermal cracking process follows a homolytic mechanism, that is, bonds break symmetrically and thus pairs of free radicals are formed. The catalytic cracking process involves the presence of acid catalysts (usually solid acids such as silica-alumina and zeolites) which promote a heterolytic (asymmetric) breakage of bonds yielding pairs of ions of opposite charges, usually a carbocation and the very unstable hydride anion. Carbon-loc ...

The commonly accepted view of the origin of the Magyars (known as Hungarians in most western languages) is that they were a nomadic people, with indeterminate and disputed origin from the Eurasian plains until the end of the 9th century AD. They were a confederacy of seven Magyar and three allied Khabar tribes; the name Hungary / Hungarian is most probably derived from the Turkish term Onogur meaning 'Ten Arrows', signifying united military strength in nomadic symbolism. In 896 they settled temporarily around the upper Tisza river basin ...

History of Hungary - High and Late Middle Ages 1000 - 1526. Hungary was established as a Christian kingdom under Stephen I of Hungary, who was crowned in December 1000 AD or January 1001 AD. He was the son of Géza and thus a descendant of Árpád. By 1006, Stephen had solidified his power, eliminating all rivals who either wanted to follow the old pagan traditions or wanted an alliance with the orthodox Christian Byzantine Empire. Then he started sweeping reforms to convert Hungar ...

In 1918, as a result of defeat in World War I, the Austro-Hungarian Monarchy collapsed. On October 31, 1918, the success of the Aster Revolution in Budapest brought the liberal count Mihály Károlyi to power as Prime-Minister. The new government officially declared Hungary an independent republic in November, after the end of the war. On 22 November 1918 the Central Romanian Council of Romanians from Transylvania announced the Hungarian gouvernment that it had assumed control of Transylvania. On 1 December 1918 the gathering of Alba Iulia (Gyulafehérvá ...

In January 1920, Hungarian men and women cast the first secret ballots in the country's political history. The votings were not totally free, because the entire left-wing either boycotted or was excluded from the voting. A large right-wing majority was elected to a unicameral assembly. In March, the parliament annulled the Compromise of 1867, and it restored the Hungarian monarchy but postponed electing a king until civil disorder had subsided. Instead, Miklos Horthy was elected regent and was empowered, among other things, to appoint Hungary's prime minister, veto legislation, con ...

The Soviet Army occupied Hungary from September 1944 until April 1945. It took almost 2 months to conquer Budapest and almost the whole city was destroyed. By signing the Peace Treaty of Paris, Hungary again lost all the territories that it gained between 1938 and 1941. Neither Western Allies nor the Soviet Union supported any change in Hungary's pre-1938 borders. The Soviet Union itself annexed Sub-Carpathia, which is now part of Ukraine. The Treaty of Peace with Hungary signed on 10 February 1947 declared that "The dec ...
