We report the phenomenon of abrupt reduction of the threshold velocity of ultrasound at a frequency of 6 MHz in a dilute homochirality solution when it undergoes a transition into the phase of the anisometric gel. The decrease observed was equal to 13% when the solute concentration was varied in the range from 0.6 to 0.8 mg/ml, i.e. when the density of the solution was changed by 0.02% (solutions of achiral analogues at these concentrations remain liquid). This is, apparently, due to the resonant interaction of ultrasonic waves with an irregular grid of the strings formed in the solution. This phenomenon allows one to evaluate the gelation threshold and is a new method for studying chiral solutions.

The methods for measuring circular dichroism, optical rotation and UV spectroscopy revealed threshold phenomena in solutions of chiral trifluoroacetylated amino alcohols. The results obtained are an independent experimental confirmation of the threshold nature of the formation of the strings and the thermally activated process of dissolution of strings in chiral solutions, which was previously established by direct microscopic examination and confirmed by IR spectroscopy and fluorescence.

During the research conducted we have found that xylomycobiota of tree plants (trees and shrubs) that are used in greening of Azerbaijan cities (Baku and Ganja) includes 31 species. It is shown that 9.7% of fungi are biotrophic, 22.6% are saprotrophic and the rest (67.7%) belong to polytrophic fungi. Among tree plants, poplar exhibits the richest xylomycobiota with 22 species of fungi found, whereas eastern sycamore has the poorest mycobiota of 9 species. Inonotus hispidus are the most widespread fungi in Baku, whereas Phellinus pomaceus and Fomes fomentarius are the most widespread fungi in Ganja

We present the results of the experimental study of the influence of selenium preparations on the morphological and biochemical reactivity of rabbit blood (puberty period) under biogeochemical conditions of the Orenburg region, which is endemic in essential micronutrients. It is found that selenium preparations can stimulate the processes of plastic exchange, hemopoiesis and lymphopoiesis. Despite the fact that ‘E-Selen’ is less efficient than ‘Selenolin®’, its effect is of more uniform and dose-sparing type.

We present the results of studies aimed to assess the ecological status of the soil cover of urban areas (Elektrougli, Moscow region) using test organisms, as well as give a comparative evaluation of soil contamination in various technogenic areas and phytotoxicity assessment of soils with different levels of anthropogenic stress. The main criteria for assessment are such integral factors as the energy of germination, seed germination of radish, development of the aerial part, and the length of the root system of seedlings.

We have studied the composition of species of activated sludge and biocenosis of Myriophyllum verticillatum. Bacteriological cultivation on a solid breeding ground for the detection of the associated microflora has shown: 1453 colonies sprouted in the activated sludge and 496 - in Myriophyllum verticillatum, which indicate a better filtration activity of whorled water milfoil. The biocenosis of the activated sludge is more variable than that of Myriophyllum verticillatum.

The structure and composition of Achillea millefolium S.L. are critically reviewed. Necessary changes are introduced in the taxonomy of the group. The nomenclature of its representatives and a set of diagnostic features are specified. The main specific forms and signs by which they differ are presented. Ecology and plant community confinement of these groups are described. It is shown that Achillea millefolium represents a single taxon with signs of continuity. The taxon comprises seven species groups. Initially these forms have been described from single samples. However, the study of a large number of specimens shows that the distinction between specific forms is purely formal.

It is shown that use of automatic control of set physical activity by the Multi Doctor program, and also a preparation trekrezan in the conditions of aero-bic fitness, promotes reduction of degree of obesity, and also gives additional motiva-tion to the engaged. Use in the course of aerobic fitness of automatic, objective con-trol of physical activity in real time improves techniques of improving and adaptive physical culture. Efficiency aerobic fitness - the trainings directed on correction of a condition of persons, having certain deviations in a state of health, increases when us-ing trekrezan in the form of biologically active additive. Trekrezan can be used, as an additional tool for increase of motivation of visitors fitness - clubs.

We consider the composition of the microflora of the river Yauza within the Mytischi city. The total microbe number is estimated on the water surface and in the depth before and after seasonal snow melting. The maximal number of bacteria is found at a depth of 50 cm to 1 m. A significant increase in the number of bacteria is observed after snow melting. The total microbe number in the river waters within the Mytishchi city is 2.5 times higher than that outside the city.

Practically healthy girls, depending on the age group, exhibit an activation of serotonin in the blood. In addition, the serotonin level is dependent on the degree of physical activity, which is established during examination of female volleyball players. Activation of serotonin is also associated with the type of nervous system and individual characteristics of the athlete. After a heavy workout (delayed training effect) the serotonin activity in the blood is relatively reduced. Apart from the degree of physical activity, we observed that the individual characteristic of psychophysiological adaptation influences the serotonin level. This relationship creates conditions for normal physiological activity in the functional system of the body and mental well-being during the training process, as well as for prevention of stress during competitions.

Under conditions of the NaCl salinity, the structural and functional organization of the chloroplasts significantly changes. Variation in the level of accumulation of pigments, in turn, leads to a change in the rate of photosynthesis. The general content and the ratio of the components of the photosynthetic apparatus, and the intensity of the process are determined by the biological nature of the plant, the phase of its development and the concentration of salts in the soil solution.

It is found that the heart rate depends on the addition to smoking. We have studied the parameters of heart rate, blood pressure and tissue oxygenation in young smokers. We have compared the parameters of heart rate, blood pressure, tissue oxygenation before and after smoking, at rest and after physical exercises. Reversible physiological abnormalities are found in the cardiovascular system in young smokers with the addiction up to 5 years.

We present the results of ecological and biogeochemical studies at the N.R. Asyka regional experimental agricultural station, which made it possible to assess the bioaccumulation of lead and cadmium in woody plants of roadside shelter belts and in field crops adjacent to roadsides and agricultural lands. It is found that the soil of shelter belts accumulates mostly lead, while the level of cadmium in soils of both the shelterbelt and adjoining agricultural lands is characterized by stability. Analysis of lead and cadmium content in the leaves of woody plants of the shelter belts and in field crops shows a comparable accumulation capacity of plants. It is found that American maple and ash have a higher accumulation capacity as compared with acacia.

We present the data on the state of blood of newborn calves with antenatal hypotrophy. It is shown that alterative processes in liver, arising in the early stages of postnatal ontogenesis, are accompanied by complex morphofunctional hematological abnormalities, including the appearance of atypical and degenerative cell forms. The data obtained supplement the information about the implementation of the compensation and reparation processes in newborn calves with a low adaptive potential and can be used for diagnostic (prognostic) purposes and the development of effective means of correction and prevention of neonatal pathology.

The scale of contamination, the range and level of fusarium toxins is estimated in winter grains of wheat and its products. We have analyzed the possible health risks associated with exposure of the population to fusarium toxins and substantiated the necessity of a systematic microbiological monitoring of fusarium to prevent them. We have improved the algorithm of studying the grain quality, providing the examination of three interrelated parameters: humidity, Fusarium, and contamination by mycotoxins. Using the data obtained we have proposed concrete and practical recommendations and further ways of scientific research to improve the grain quality.

Children with different levels of mental disorders demonstrate different locomotive abilities, which calls for the necessity of a differentiated approach to the process of their physical improvement. We present the results of investigations in age-related changes of power abilities in students of popular educational institutions and children with different levels of mental disorders. The results confirm similarity of general mechanisms of psychomotor development in normal and intellectually affected genesis. The special features of the development are noted under the conditions of intellectually affected genesis.

We describe the subject and tasks of psychogeography as a new interdisciplinary area of scientific knowledge. The special role of philosophy (dialectics, systems theory, synergetics) and psychological (environmentalism, behaviorism, neurolinguistic programming) studies is noted in the formation of geographical ideas concerning the interaction between man, nature, and society. We present a review of conceptual studies on the effect of man on geosystem and of geosystems on man and society: behavioral, cognitive, humanistic, humanitarian and imagi-nal geography, anthropogeography and cultural geography.
