Elemental and chemical analyses and physical tests were conducted on 36 samples of Middle and Upper Pennsylvanian coals from southeastern Kansas. Concentrations of 35 minor and trace elements in these coals were statistically compared with concentrations in coals of similar rank and age from other areas in the western region of the Interior Coal Province, showing that Kansas coals have significantly higher concentrations of copper, arsenic, and lead. The zinc content in Kansas coal samples ranges from 160 to 51,000 ppm (whole-coal basis), the maximum value being the highest zinc value reported for U.S. coals. Cadmium content also has an extreme range, from less than 1.0 to 160 ppm (whole-coal basis), the maximum value being one of the highest cadmium values reported in U.S. coals. The apparent ranks of these coal samples range from high-volatile B to high-volatile A bituminous coal. Most samples of Middle Pennsylvanian coals from the major coal-mining area in Bourbon, Crawford, and Cherokee counties are high-volatile A bituminous coal. Arithmetic mean values for proximate analyses of coals (as-received basis; n = 25) show these coals to be 15.5% ash, 35.3% volatile matter, 45.9% fixed carbon, and 3.3% moisture and to have a heat of combustion of 11,910 Btu/lb. Arithmetic mean values for ultimate analyses of the coals show these coals to be 4.9% hydrogen, 65.3% carbon, 1.2% nitrogen, 5.5% sulfur, and 7.7% oxygen. The geometric mean values of these Kansas coals are 3.03% pyritic sulfur, 1.25% organic sulfur, and 0.2% sulfate sulfur.

Abstract Indoor radon (222Rn) was surveyed in a total of 141 individual houses and apartments used precalibrated passive PicoRad Detectors. The radon activity in the soil gas around the dwellings was simultaneously measured. The arithmetic mean values of indoor radon concentrations for detached houses, old buildings (up to four-stories), prefabricated blocks of flats (mostly five stories) and high-rise residential buildings (10-stories) were:, 70.9; 46.5; 38.4, and 56.6 Bq m−3, respectively. The average arithmetic mean value for all measured rooms equals 51.8 Bq m−3. The calculated average effective dose from indoor radon for the local population was equal to 2.2 mSv.

The article presents theoretical substantiation and empirical research of the problem of the influence of the family structure on the development of creativity of children of preschool age. The relationship between creativity and family type, number of children in the family, birth order, and intervals between births is analyzed. Peculiarities of influence of family structure (by the number of children) for the development of creativity of children of preschool age are researched. The absence of significant differences in partial (productivity, flexibility, originality) and a general indicator of verbal creativity of children with one child, small and large families has been experimentally established. Research of figurative creativity allowed to identify significant differences in partial indicators of productivity and originality, and the general indicator of figurative creativity: the highest arithmetic mean values are determined in the group of children from small families, and the lowest - in the group of children from large families. In children brought up in single children families, the highest arithmetic mean value is revealed by the partial indicator of the name, and the lowest - in children from large families. In children of preschool age from single, small, and large families no significant differences by partial indicators of the development and resistance to the closure were found. The heterogeneity of verbal and figurative creativity structure is determined in children of preschool age in all types of families. Significant differences were found in the general indicators of creativity: the highest arithmetic mean value was determined in the group of children from small families, and the lowest - in children from large families. Conclusions are made that children from small families are the most creative, and children from large families - the least.

The aim of the study - to analyze the content of the muscular component of the body in girls of 16-20 years old belonging to different constitutional groups. Material and methods. 729 girls (400 at the age of 16-17 years, and 329 at the age of 18-20 years) were explored by the method of complex anthropometry and bioimpedance. Statistical processing of digital materials was to calculate the arithmetic mean values, their errors. The evaluation of the reliability of differences in arithmetic mean values was carried out by the method of confidence intervals. Results. Girls of leptosomic groups of the constitutions are identified in 20.5% of cases, mesosomic group - in 34,2% of cases, megalosomic group at 35,7% of cases, the indeterminate group and in 9,6% of cases. The obtained data on the content of muscle mass indicate that the studied indicators significantly depend on the belonging of girls to a particular constitutional group. The absolute content of muscular components of the girls of leptosomic group of the constitution is substantially less than women of other constitutional groups. Conclusion. The study received a quantitative of girls of different constitutional groups in the studied population; obtained data on the characteristics of the absolute and the percentage of muscular component of the body depending on the type of constitution, allow us to conclude about the individual variability of the severity of these indicators and the data obtained can be used to create the passport's physical development in contemporary conditions.

ABSTRACT The concentration of testosterone (ng/100 ml; mean ± sd) has been determined in peripheral venous plasma at 4 hourly intervals for 24 h from 9 non-pregnant women (39.8 ± 11.8) and 9 during late pregnancy (70 ± 32). In addition, the level of this hormone has been measured in samples of plasma removed daily (between 08.30 and 10.00 h) throughout 9 ovarian cycles (41.6 ± 11.8), and weekly from 10 women during gestation (57.6 ± 14.7). The results show that there is considerable individual variation in both the concentration and pattern in serial samples over the respective time scales. The values of the arithmetic mean from non-pregnant subjects show that there is a tendency for the concentration to be lower between 20.00 and 04.00 h. However, the differences between the values at defined times over a 24 h period are not statistically significant. During the ovarian cycle 3 subjects had peak values during the peri-ovulatory phase, 2 in the luteal, 1 in the follicular and 3 showed no consistent pattern. There was no significant difference in values (40.9 ± 11.8, 41.9 ± 11.9 and 41.8 ± 11.9) for the 3 phases of the cycle. There is a significant rise in the concentration of plasma testosterone during pregnancy (P< 0.0005), but the pattern of the arithmetic mean is not related to the corresponding values for progesterone or oestradiol. During late pregnancy (34 weeks to term) there is a change in the nycterohemeral pattern, with the highest mean values occurring between 16.00 and 04.00 h. The results are discussed.

The article deals with the results of studies related to the testing of the proposed method of rapid diagnosis of plants conducted in the production conditions of Agrocomplex "Churilovo". It was found that the absorption spectrum of the leaf apparatus of cucumber plants in the control variant (substrate – mineral wool) and the experimental variant (substrate - agroperlite) differed insignificantly: the arithmetic mean values of chlorophyll absorption in the control and experiment were 3,668 and 3,772, respectively; carotenoid absorption - 3,560 and 3,403; cytochrome absorption - 2,681 and 2,645, respectively. There were minor differences in the content of micro - and macronutrients in plant leaves and yield. It is revealed that the proposed method of rapid diagnosis, based on the analysis of the absorption spectra of the sheet apparatus, allows to obtain results comparable to the results of chemical analysis and yield assessment, and can be used to diagnose the condition of plants.

Male and female Ss made comparative judgments of paired sets of simultaneously presented income stimuli. The pairs were constructed so that the sum of the values was higher in one set than in the other, while the mean income was simultaneously higher in the latter set than in the former. When the incomes within a set were represented as all belonging to the same person or when the incomes were attributed to different members of a family, both men and women tended to rate higher in economic status whichever sets of stimuli had the higher sums in direct relation to the manipulated discrepancy between sums. When the same stimuli were attributed to different members of a group, both sexes rated higher in economic status whichever sets had the higher arithmetic mean values in direct relation to the manipulated discrepancy between arithmetic means. The significance of this finding is in demonstrating that the stimulus-combination rule in impression formation is at least partially predicated upon situational determinants and that neither simple summation nor simple averaging is an exclusively valid or invalid combinatory principle.

The aim of the study was to investigate the content of the muscular component of the body in girls, aged 16–20, with different somatotypes.Material and methods. The study included 500 females, aged 16–20, representatives of the Slavic ethnic group, residents of Moscow and the Moscow region. They were divided into two groups: 16–17 and 18–20 years old (250 girls in each group). The diameter of the wrist and ankle, wrist and calf circumferences (mm), thickness of the dermal-fat fold of the back, shoulder, abdomen and thigh (using a calipometry method) were calculated in girls of all groups. The content of the muscular component of the soma was also calculated by bioimpedansometry (using a Russian device "ABC-01 Медасс"). Statistical processing of findings included calculation of their arithmetic mean values, errors. The significance of differences was determined using parametric and nonparametric criteria (Student and Fisher criteria) depending on the type of distribution in the sample.Results. Heterogeneity of the population was revealed when determining a somatotype: inclusion into a particular constitutional group insignificantly modifies with the transition from 16–17 to 18–20 years of age. Mesosomy was a predominant feature in girls of both age groups (48% of all studied girls aged 16–17 and 40.0% of all studied girls aged 18–20). Girls with megalosomal body type constituted 24.0 and 26.5%, respectively; girls with leptosomal body type constituted 20% in all age groups; girls with undefined body type constituted 8.0% and 13.5%, respectively. The content of the muscular component of the soma demonstrated significant constitutional differences between these parameters. In comparison of the studied groups, there was an insignificant increase in the absolute indices of the muscle component with a decrease in the relative indices - the mass of the muscle component to body weight – with increasing age.Conclusion. The data obtained demonstrate significant constitutional features of the absolute and relative (percentage) content of the muscle component of the body as an important aspect of the female physical status. This information is relevant for both theoretical and practical medicine.
