Characteristics of the snow cover distribution on the coast of Lake Baikal
Get PDFThe paper presents results of studies of the dynamics of snow cover characteristics along the Lake Baikal coast for the years 1961–2009. Statistical characteristics of the following elements: snow depth, duration of the period with snow cover, dates of onset and destruction of snow cover, were calculated from data of local meteorological stations. Mean annual snow depth in the region varies from 1 to 36 cm, while the maximal ten-day values changes from 12 cm on the West coast up to 60–86 cm on the East coast. Mean duration of the snow cover in the Baikal region is 138 days, while on the East coast it lasts for 178 days, and on the West one – for 126 days. Long-term trends of the snow cover characteristics are mostly statistically insignificant. However, at the end of the above period dates of the snow cover onset and destruction has been shifted to earlier dates. The inter-annual variability of these dates reaches 30 days. A linear dependence of the snow cover depth on the mean air temperature and the precipitation amount for the cold season was revealed with correlation coefficients from 0.31 to 0.89
Comparative characteristics of the state of the motor function of boys and girls aged 4-5 years
No full text<p>It was considered the reliability of differences in the state of motor function between boys and girls aged 4-5 years. The study was conducted on the basis of pre-school establishments of Kirovohrad involving girls (n = 212) and boys (n = 188) aged 4-5 years. It is used a set of indicators that characterize motor skills, physiological and functional capacity of children. Identified the absence of significant differences in most parameters, except flexibility, performance of boys and girls of 4 years old. In 5 years old children differences in motor function of the state of most of the indicators are significant differences, except high-speed performance abilities and functional capacity of the system. At the organization of the educational process in physical education should be differentiated pedagogical influence on sexual differences.</p
Dual-pulse laser-induced breakdown spectrometry of bronze alloys and coatings
No full textThe possibilities of using dual-pulse laser atomic-emission spectroscopy for both the estimation of elemental
concentrations in bronzes and layer-by-layer analysis of a bronze coating on steel bead wire have been examined. Two methods have been proposed to lower the radiation flux density q in studies of thin metallic layers. These were based respectively on using optical filters and defocusing the radiation with respect to a
sample surface. It has been found that the decrease of q results in reducing the influence of tin on copper
evaporation under dual-pulse laser irradiation

Clinical psychological parallels in cardiovascular pathology and possibility of psychoprophylaxis
No full textВ останні роки приділяється суттєва увага вивченню особливостей психосоматичної дисфункції у пацієнтів з кардіоваскулярною патологією та розробці методик психокорекції. Проведене нами дослідження клініко-психологічних характеристик у 85 хворих з серцево-судинними захворюваннями дозволило виявити певні співвідношення патогенних і саногенних психологічних чинників, що відбивають виразність адаптивних ресурсів у обстежених. При ішемічній хворобі серця (ІХС) (38 чол.) у нашому дослідженні були виявлені психологічні фактори структури особистості хворих, що містили патогенні адаптивні особливості у вигляді ігнорування виникаючих почуттів і емоцій, категоричності домагань, регуляторної пасивності і соціальної ізольованості, які визначені мішенями психокорекції при даному захворюванні
