Some features of the bioelectric activity of the muscles with prolonged hypokinesia
The effects of prolonged hypokinesia, brought on by confinement to bed and the attendant lack of motor activity, on the bioelectric activity of muscles are studied. Electromyographic measurements of amplitude and frequency indicators of muscular bioelectric activity were analyzed
A method for production of phytomineralsorbent, physical and chemical properties of it, effect on the living systems and the quality of the livestock industry products
Numerous experimental studies have shown that the sorption-active substances can clarify the reservoir, soils, drinking municipal water from unwanted impurities with a sufficient degree of effectiveness; eliminate the potentially toxic for health chemicals of different chemical nature from human body. This is ensuring their using in the animal production practice, veterinary medicine and medicine. The main purpose and focus of this study are associated with the solution of problems of the maintaining physiological and biochemical status of live-stock animals. It provides their productivity and biological value of obtained product
Late Reheating, Hadronic Jets and Baryogenesis
If inflaton couples very weakly to ordinary matter the reheating temperature
of the universe can be lower than the electroweak scale. In this letter we show
that the late reheating occurs in a highly non-uniform way, within narrow areas
along the jets produced by ordinary particles originated from inflaton decays.
Depending on inflaton mass and decay constant, the initial temperature inside
the lumps of the overheated plasma may be large enough to trigger the
unsuppressed sphaleron processes with baryon number non-conservation, allowing
for efficient local electroweak baryogenesis.Comment: 4 pages, 2 figures, revtex
Influence of L-lysine sulfate on containing of vitamins and minerals in the body of broiler chickens
Experimental researches have shownthatthe L-lysine sulfate (the product of microbiological synthesis) has a positive effect on metabolism of vitamins A, E, C in the liver and minerals calcium and phosphorus in the blood and bones of broiler chickens. The dose of L-lysine sulfate of 800 mg-kg" 1 and 1000 mg-kg-1 weight body has influence on increasing vitamins level in the liver. Was observed, that indexes of calcium and phosphorus are increased in the blood but it’s decreased in the bones of broiler chickens. This results are necessary for Veterinary Pharmacology Consults and official practically using in agricultural sectors of Russian Federatio
Some constraints on the Yukawa parameters in the neutrino modification of the Standard Model (nuMSM) and CP-violation
The equations connecting elements of the Yukawa matrix to elements of the
active neutrino mass matrix in the \nu MSM theory (an extension of the Standard
Model by a singlet of three right-handed neutrinos) was analyzed, and explicit
relations for the ratio of the Yukawa matrix elements through elements of the
active neutrino mass matrix were obtained. This relation can be used for
getting more accurate constraints on the model parameters. Particularly, with
the help of the obtained results we investigated CP-violating phase in the \nu
MSM theory. We demonstrate that even in the case when elements of the active
neutrino mass matrix are real the baryon asymmetry can be generated also.Comment: 14 pages, 2 figures, many clarifications and references adde
Where to find a dark matter sterile neutrino?
We propose a strategy of how to look for dark matter (DM) particles
possessing a radiative decay channel and derive constraints on their parameters
from observations of X-rays from our own Galaxy and its dwarf satellites. When
applied to the sterile neutrinos in keV mass range, it allows a significant
improvement of restrictions to its parameters, as compared with previous works.Comment: 5 pp, revtex; v3: 1-sigma limits have been replaced by more
