Male rats of the Wistar strain were examined one day and 26 days after the 20-day space flight on board the Cosmos 690 biosatellite. On the 10th flight day the animals were exposed to 24-hour gamma irradiation: some animals were irradiated at a dose of 220 rad and the others at a dose of 800 rad.

As a result of a combined effect of prolonged weightlessness and ionizing radiation at a dose of 800 rad aboard the biosatellite Cosmos-690, the recovery time of certain parameters of fluid-electrolyte metabolism (hydration of the body, balance of sodium, potassium, calcium) was longer than that for

Rat experiments on the Cosmos biosatellites demonstrated that the percentage of renal excretion of consumed water after flight was lower than after synchronous experiment. This can be attributed not only to water retention but also to a different level of extrarenal losses postflight. Weightless

The conductor-like screening model for real solvents (COSMO-RS) is applied to the prediction of the aqueous solubility of chlorobenzenes (CBZs) in a liquid-liquid and liquid-solid equilibrium. The solubilities of CBZs at temperatures ranging from 5 to 60 degrees C are reported, and the enthalpies of

Bone resorption was measured directly in flight and synchronous control rats during COSMOS 1129. Continuous tracer administration techniques were used, with replacement of dietary calcium with isotopically enriched 40Ca and measurement by neutron activation analysis of the 48Ca released by the

The first representatives of the radical anions of silatranes XSi(OCH2CH2)3N – organic derivatives of the pentacoordinate silicon atom (X = Ph, 1; p-NO2PhO, 2a; m-NO2PhO, 2b; o-NO2PhO, 2c) – were obtained and characterized by EPR spectroscopy. The structure of 1(−˙), 2a(−˙), 2b(−˙), and 2c(−˙) in

A series of new self-buffering ionic liquids (ILs) based on Good's buffers (GBs) anions and the tetrabutylphosphonium cation ([P4444]+) was here synthesized and characterized. The self-buffering behaviour of the GB-ILs was confirmed by measuring their protonation constants by potentiometry. Further,

Sensory and microbiological characteristics of pond-raised freshwater silver perch (Bidyanus bidyanus) fish, during cold storage over a period of 25 days were evaluated. Whole fish (averaging 400 g each) were stored in cold storage rooms at either 0 to 2 degrees C, 5 degrees C, or 5 degrees C +
