Rimcazole (BW 234U) is a potential antipsychotic agent which in open-clinical trials appears to be effective in acute schizophrenic patients. In the present study, rimcazole was found to block the specific binding of [3H]-(+)-SKF 10,047 to sigma sites in rat and guinea pig brain (IC50 = 5.0 X 10(-7) M).

Uranium is accumulated in granites and sedimentary rocks by the geological process. The most common uranium-containing minerals are; uraninite which is a complex of uranium oxides (UO 2 /UO 3), autunite (a hydrated calcium uranium phosphate) Ca (UO 2) 2 (PO 4) 2.10-12H 2 O, brannerite (a uranium calcium cerium-titanium iron oxide) UTi 2 O 6, and carnotite (a hydrated potassium uranium vanadate

Mark; Abstract High internal radiation doses can result from food, contaminated by radionuclides from for example nuclear fallout. Uranium (234U/238U) and oxygen (δ18O) isotopes were measured in eight boreal streams and in seven deep groundwater wells adjacent to these streams. The measurements covered an entire spring flood cycle from winter baseflow conditions, through the peak flow and into the early summer, thereby capturing much of the hydrological dynamics in these systems.

In natural uranium and in uranium ore, 234 U occurs as an indirect decay product of uranium-238, but it makes up only 0.0055% (55 parts per million) of the raw uranium because its half-life of just 245,500 years is only about 1/18,000 as long as that of 238 U. 234 U is an indirect decay product of 238U. 238 U decays via alpha decay (by way of thorium-234 and protactinium-234) into 234 U. 234 U decays via alpha decay into 230 Th, except very small fraction (on the order of ppm) of nuclei which decays by spontaneous fission.

Each ejected alpha particle has kinetic energy of approximately 5.6 MeV. How fast is this particle moving, i.e. what is its velocity in m/s? How does this velocity compare to the speed of light in a vacuum?
