| | | | | free radicals: Encyclopedia II - Free Democratic Party of Switzerland - Platform As a classical Liberal party, the FDP generally opposes state intervention in social and economic affairs. Based on its conception of the individual as free, sovereign and self-responsible, it rejects notions of a welfare state and paternalist regulation that became common in Liberalism in other European countries in the late nineteenth century. The FDP professes faith in the free market, free trade, economic deregulation and the rule of law.
As regards specific issues, it is often labeled progressive with regard to social policy, sup ...

| | | | | free radicals: Encyclopedia II - Past and present anarchist communities - Historical examples of societies successfully organized according to anarchist principles In recent history there have been numerous instances of collapse of state authority, sometimes prompted by war but also often due to implosion of the state. In some cases, state collapse is followed by lawlessness, rioting, looting and, if disarray lasts long enough, warlordism. Although such societies are often described as anarchy, they are not organized according to anarchist principles.
However, there are instances in which a society peacefully organizes itself without a government or other form of centralized power, along philoso ...

Past and present anarchist communities - Israeli Kibbutz Movement.
The Kibbutz movement was an outgrowth out of socialist strands of the Zionist Movement, many of which stressed Arab-Jewish cooperation. The movement revolved around anarchist principles of non-hierarchy, self-management of production, and direct democracy. The early kibbutz collectives could be seen t ...

| | | | | | free radicals: Encyclopedia II - Radiation therapy - How It Works Radiation therapy works by damaging the DNA of cells. The damage is caused by an electromagnetic, electron or proton beam directly or indirectly ionizing the atoms which make up DNA chain. Indirect ionization happens as a result of the ionization of water, forming free radicals, notably hydroxyl radicals, which then damage the DNA. In the most common forms of radiation therapy, most of the radiation effect is through free radicals. Because cells have mechanisms for repairing DNA breakage, where the DNA is broken on both strands of the DNA ar ...

| | | | | | free radicals: Encyclopedia II - Radiosurgery - How it works The fundamental principle of radiosurgery is that of selective ionization of the tissue to be operated upon, by means of high-energy beams of radiation. Ionization is the production of inorganic ions which are usually deleterious to the cells, by forming free radicals that are harmful to the cellular and nuclear membranes, and even to the RNA and DNA chains of the cells, producing an irreparable damage to these structures and then the cell's death. Thus, biological inactivation is carried out in a volume of tissue to be treated, with a preci ...

| | | | | | | | | | free radicals: Encyclopedia II - Superoxide dismutase - Physiology The superoxide anion radical (O2-) spontaneously dismutes to O2 and H2O2 quite rapidly. However, SOD has the fastest turnover number (reaction rate with its substrate) of any known enzyme. In fact, its rate is diffusion-limited. Thus, under real-world intracellular conditions, SOD greatly reduces the ambient level of the dangerous superoxide radical.
The presence of SOD has been shown to help protect many types of cells from the free radical damage that is important in aging, sene ...

| | | | | | free radicals: Encyclopedia II - Aging senescence - Theories of aging The process of senescence is complex, and may derive from a variety of different mechanisms and exist for a variety of different reasons. However, senescence is not universal, and scientific evidence suggests that cellular senescence evolved in certain species as a mechanism to prevent the onset of cancer. In a few simple species, senescence is negligible and cannot be detected. All such species have no "post-mitotic" cells; they reduce the effect of damaging free radicals by cell division and dilution. Such species are not immortal, however ...

| | | | | | free radicals: Encyclopedia II - Environmental movement - Environmental rights Many environmental lawsuits turn on the question of who has standing; are the legal issues limited to property owners, or does the general public have a right to intervene? Christopher D. Stone's 1972 essay, "Should trees have standing?" seriously addressed the question of whether natural objects themselves should have legal rights, including the right to participate in lawsuits. Stone suggested that there was nothing absurd in this view, and noted that many entities now regarded as having legal rights were, in the past, regarded as "things" ...

| | | | | free radicals: Encyclopedia II - Environmental movement - Role of science Largely due to this political critique and confusion, and a growing concern with the environmental health problems caused by pesticides, some serious biologists and ecologists created the scientific ecology movement which would not confuse empirical data with visions of a desirable future world.
Today it is the science of ecology, rather than any aesthetic goals, that provide the basis of unity to most environmentalists. All would accept some level of scientific input into decisions about biodiversity or forest use. Conserva ...
