On the equations with property Î1
In the qualitative theory, Atkinson’s and Belogorets’ indications of variability of all correct decisions of the second-order nonlinear differential equations are generally well-known. There are no such criteria for the linear equations. The author gives the effective necessary and sufficient condition in order that each not trivial decision of the linear equation was varying or monotonously aspired to infinity at unlimited increase of argument.

Growth, a mineral feed and production of east goat’s-rue (Galega orientalis L.) at applying increasing portions of phosphorous-potash fertilizers
Nowadays the problem of formation of a highgrade forage reserve with the high contents of protein is solved by expansion of crops of zoned varieties of fodder crops, as well as by introduction in manufacture of new cultures with the high contents of protein. One of them is east goat’s-rue. The important factor for increasing east goat’s-rue production is providing crops with phosphorus and potas-sium. During long-term cultivation of this culture it is rational to bring phosphorous-potash fertilizers in a stock for several years that results in a significant economic gain.

Correlation of the basic cytokines in blood of oncologic patients and healthy donors
The following distinctions have been revealed in blood of oncologic patients with solid neoplasms in comparison to donors: disbalance in mole ratios of serum cytokines IL-4/IL-2, absence in blood of L-12 and blocking of expression of mRNA L-12 by mononuclear cells (MNC) of oncologic patients. The significance of the obtained data in immune pathogenesis of neoplasias is discussed.
Studying antagonistic activity of hemolytic E. coli singled out from patients with gastrointestinal diseases
A study was made of antagonistic activity of hemolytic Escherichia (E. coli Hly +) singled out from patients with gastrointestinal diseases in terms of closely related and unrelated microorganisms and its connection with presence of fermentative activity. The author revealed low antagonistic action of bacteriocins of the strains under investigation in relation to “Colibacterin” and to typical E.coli and high, in relation to conditional – pathogenic and pathogenic enterobacteria, lactobacteria and Staphylococcus aureus. Of three groups of E.coli Hly +, the greatest antagonistic activity in the investigated indicator groups is displayed by strains with slightly expressed fermentative activity, the least antagonistic activity is manifested by lactosenegative.

Psychological and physiological features and mechanisms of adaptation of young football players at the children sports school to the increased muscular activity
Researches were carried out of the psychological and physiological status and psychological-emotional state of the young football players engaging in a mode of children-youth sports school of the Olympic reserve. The authors revealed specific features of reaction of nervous system on testing loading, determined speed, lability and a degree of disbalance of nervous processes and established the level of psychological-emotional pressure depending on age and experience in training. On the basis of a combination of the specified factors characterizing psychological and physiological features of the individual, his specific psychological and physiological status was determined. The obtained results are of interest to those who makes choice of tactics and strategy of training taking into account psychological and physiological features of the young sportsman and his current psychological and physiological state.

Object-oriented digital model of the topography
The authors offer the physical and mathematical digital model describing the real Earth’s surface, providing discrete and continual representation and the analysis of the topography and dynamic modelling in three-dimensional geoinformation space. The physical and mathematical model of a topography is created as a result of integration of two models: vector discrete – continual representations of a surface of the topography on the basis of a method of “spherical quadro angulation” and raster physical model of gravitational transfer.
