Nanocrystalline graphite films nucleation by the radio frequency bias pretreatment.

New method for nucleation of different nanocrystalline carbon films upon monocrystalline Si substrate was proposed. The process is based on a combination of microwave and radio frequency plasma assisted chemical vapor deposition methods. Potential of the method for nucleation was demonstrated by deposition of nanocrystalline diamond film in pure microwave plasma in one process, immediately after "seeding" procedure.

[Complex technogenic load and morbidity of workers engaged in synthetic rubber production].

Workers engaged into synthetic rubber production are exposed to multicomponent chemical mixtures, noise, general vibration (in excretion workshops), unfavorable microclimate parameters, physical and psychoemotional overload.

[Prevention of health status impairment in children under conditions of the Extreme North].

Under the influence of climatic and geographic conditions of the Arctic, 7-9-year-old children develop some functional tension, as evidenced by studies of their thermal reactions and cardiorespiratory system. Ethnic thermoregulatory features were found, which involved retained sensations of thermal comfort at lower skin temperatures and a higher gradient of skin temperatures in the trunk and extremities. In the morbidity pattern of young school-children, there is a prevalence of acute and chronic respiratory diseases whose major causes are cooling and recooling.

[Impact of the climate of the Extreme North and education conditions on young school children].

The scientifically grounded sound regimen is required for schoolchildren, younger ones in particular, who most experience unfavourable environmental factors. Particular emphasis should be laid on the regulation of educational burden at primary school since the irrational distribution of classes leads to the development of fatigue mainly in young schoolchildren and hence to lower working capacities and poor comprehensibility. The investigations have supported the earlier data that the children show the strained body's functional status which is deteriorated by the influence of educational burden.

[Psychoemotional status of primary schoolchildren in the Far North].

Social and natural factors, environmental pollution and general school reforms create prerequisites for deterioration of children's mental health in the Arctic. Therefore, it is necessary to modify an educational process, especially to transfer classes to later hours than those in the temperate zone of the country.
