Using a semi-automatic image analyzer MOP Videoplan, a quantitative histomorphometric investigation of sponge bone of tibial metaphyses, iliac crests and lumbar vertebrae of monkeys kept for 14 days in the head-down position (at -10 degrees) was carried out. This exposure was found to cause spongy bone reduction in all the above bones. The lowered number(More)
In the present study, we describe correlates of 30-day cigarette and alcohol use among two samples of high school students, one in the Russian Federation (n = 365), and one in the United States (n = 965). The correlates used in the analyses are based on the theory of triadic influence, which organizes predictors of adolescent substance use into three(More)
We describe correlates of drug use-consequences related variables (addiction concern, problem consequences, and drinking alcohol/using drugs while driving) among two samples of high school students, one in the Russian Federation (n = 365), and one in the United States (n = 965). The correlates used in the analyses are based on the Theory of Triadic(More)

Rabbits were exposed to vertically directed UV-B radiation (280-320 nm) 5 days a week during 10 months with daily dose 6.5 J/m2 (biological effective daily dose 0.83 J/m2). Within the first week expressed photokeratoconjunctivitis was observed, but to the end of third week state of cornea and conjunctiva became practically normal. Transparency of intra-eye(More)
In recent years new methods of nonlinear non-destructive testing (NNDT) have been developed. When ultrasonic waves are passing through the dangerous micro-heterogeneities (microcracks, debondings, delaminations and microstructural material damages) modification of the acoustic contact area between the opposite surfaces of these heterogeneities takes place.(More)
Men and animals (dogs) shared an enclosed environment for 30 days. The microorganisms on their skin and in the air were examined. Specific attention was given to staphylococcal pathogens that are potential causal agents of infectious diseases in enclosed bio-objects. The data obtained suggest that conditional pathogens can be exchanged between men and(More)
