In this paper, using concepts from the nonstandard physical world, the linear effect line element is derived. Previously, this line element was employed to obtain, with the exception of radioactive decay, various experimentally verified special theory relativistic alterations in physical measures. This line element is now used to derive, by means of separation of variables, an expression that p...
sir, the big flooding in thailand in 2011 is one of the problematic flooding in asia. it causes several destroying to many things in the disaster areas. an important concern is on the effect on the setting with the radioactive elements usage. in thailand, there are some places with radioactive elements including to the university, hospital as well as radioactive research center. luckily, during...
Sir, the big flooding in Thailand in 2011 is one of the problematic flooding in Asia. It causes several destroying to many things in the disaster areas. An important concern is on the effect on the setting with the radioactive elements usage. In Thailand, there are some places with radioactive elements including to the university, hospital as well as radioactive research center. Luckily, ...
At late phases the powering of supernova light curves is often provided by the decay of radioactive elements synthesized in the explosions. This is unambiguously revealed when the light curve decline follows the half life time of the decaying elements, and the bolometric luminosity then directly provides the mass of ejected radioactive material. I will focus on the best observed element, Ni, an...
Otto Hahn was a German innovative chemist. He had discovered various radioactive elements, as well as the nuclear fission. He finally received the Nobel Prize for his participation in the atomic energy project, which Hahn and others considered that could be a factor used for peaceful means like cheap electricity and cheap industrial products. His greatest discovery though in oncology was mesoth...
The intravenous administration of emulsified fat in concentrations suitable for nutritional purposes is not applicable for clinical use because an emulsion stabilizer free of undesirable effects has not yet been developed. Pending the availability of a satisfactory stabilizer, the possibility of parenteral administration of fat by other routes deserves further exploration. Data reported on the ...
The Earth’s surface processes are predominantly controlled by the interaction between the Earth’s internal heat and solar radiation. Surface heat-flow measurements reflect the increase in temperature with depth, which results in flow of the Earth’s internal heat from the core, through the mantle, to the surface. Heat-flow is highest in volcanically active regions and is lowest near oceanic tren...
