[The investigation of the composition of liquid radioactive waste].

In investigation the process of composition sediment of liquid unorganic radioactive waste, that are forming in cistern-selectors at PNPI RAS, it was discovered apart from great quantity of ions of different metals and radionuclides considerable maintenance of organic material (to 30% and more from volume of sediment) unknown origin. A supposition was made about its microbiological origin. Investigation shows, that the main microorganisms, setting this sediment, are the bacterious of Pseudomonas kind, capable of effectively bind in process of grow the radionuclide 90Sr, that confirms the potential posibility of using this microorganisms for bioremediation of liquid low radioactive wastes (LRW).

[New method of studying membrane hydrolysis and transport as well as metabolic processes in the small intestine in vitro (everted small intestinal sac with bilateral oxygenation)].

The effect of bilateral oxygenation (from mucosal and serosal surfaces) of the small intestinal preparation on glucose accumulation has been investigated. It has been demonstrated that such a type of oxygenation significantly (two fold) increases the absorption of glucose as compared to that under oxygenation only from musocal surface. This data sugested that oxygenation from serosal site of the small intestine had an important role in the transport of free glucose.
