Lizogub V.S., Makarenko N.V., Yukhimenko L.I., Khomenko S.N., Kozhemyako T.V. The role of the properties of the basic nervous processes and psycho-physiological functions in activity of the operators of cellular connections
Abstract. Functional activity (FANP) power (PNP) and balance (BNP) neural processes, evoked activity and hemodynamics of the brain, memory function and attention, sensorimotor and autonomic reactivity in mobile operators was investigated with using of computer techniques. First in the processing of auditory information was identified individual psychophysiological features ensure operators professional activity. Persons with high and medium level properties of the basic nervous processes were more capable of processing information. Operators of low level of basic nervous processes had fewer redactions, low reactivity of the nervous system, sustained attention and memory, shorter intervals between N1-P2, P2-N2, N2-P3, P3-N3 and large latent periods components N1, P2, N2, P3 evoked cognitive potentials of P300. They were had higher power values of SDNN, LF and HF heart rate and low amplitude- frequency component, high bisferious index and high values of the tone of the large vessels of the brain.

Bogdanovskaya N.V., Malikov N.V. Evaluation of Dynamics of Changes in Different Ways Arginine Metabolism Activity under Adapttion to Physical Stress
Abstract. A survey of 29 trained and untrained youths aged 18 to 20 years was carried out. It has been shown that the optimal level of adaptation of a trained body to prolonged and intense physical exercise is provided by the activation of not only the constitutive calcium-dependent nitric oxide synthesis, but also by oxidative arginase metabolism of arginine, which yields a range of important low-molecular bioregulators and antioxidants, including urea. Significant reduction in the functionality of the body of trained youths at the end of competition period and as a consequence the manifestation of disadaptation signs correlates with increased oxidative calcium independent nitric oxide synthesis and its non-oxidative synthesis due to reutilization of stable circulating NO metabolites.

Kovalenko S.O., Kudij L.I., Lutsenko O.I. Peculiarities of male and female heart rate variability
Abstract. In 118 healthy men and women parameters of wave structure of heart rate at rest in the lying position, during tilt-test and psychoemotional load were determined. In 32 women the registration was realized three times, namely during follicular phase, ovula- tion and luteal phase of ovarian-menstrual cycle. It was observed that variability of male and female heart rate at rest in the lying po- sition is substantially different due to greater general power of R-R-interval oscillation spectrum in men. In vertical position and un- der psychoemotional load the decreasing of general spectrum power in women was greater than in men. Also the power reactivity and its distributions in heart rate low frequency range considerably differ in direction and amplitude. Observed during the repeated measurements female lower reproducibility of the parameters of heart rate wave structure can be explained by changes in female or- ganism that depend on ovarian-menstrual cycle.

Bukov Y.A., Burbanova O.N. Performance evaluation of respiratory mechanics in pulmonological degree of risk in older women
Abstract. The respiratory system undergoes regular changes in the aging process of life. There have morphological and functional changes in all parts of the respiratory system. Especially expressed considerable range of changes recorded in indices mechanics of breathing: breathing rhythm quickens, increased minute ventilation to vary the ratio between the lung and alveolar ventilation, signif- icantly increased respiratory physiological dead space and reduced the proportion of the alveolar ventilation in the structure of the minute volume of respiration. This situation contributes to their stagnant processes in the bronchi. The studies of mechanics of breathing and ventilatory function in elderly women revealed various levels of ventilatory capacity. In this regard, in order to identify patterns that define a certain level of ventilatory capacity, all the women were divided into three groups: surveyed with ventilatory abilities within the age norm, with moderately reduced and with sharply reduced ventilatory abilities. The study noted features of respiratory mechanics suggest a pulmonary risk in all subjects, the extent of which is most pronounced in women with low ventilatory capacity. In the parameters of pulmonary ventilation all subjects exceeded the value of the physiological norm. Important is the role in the manifestation of which is given indicators of expiratory vital capacity, inspiratory reserve volume, expiratory reserve vol- ume and inspiratory volume. As is known, increased pulmonary ventilation, resulted in increased energy expenditure of respiratory muscles. In this context the increase in resting energy expenditure reflects the violation of the principle of economizing function and may indirectly indicate a decrease in reserves and more effort of the bronchi. Obviously, identified ventilation high reactivity at rest in elderly women is determined by morphological changes in the lungs and the respiratory structure can also be seen in a manifesta- tion of pulmonary risk. At the same time maintaining a stable pulmonary ventilation was provided in the surveyed reciprocal rela- tionship between respiratory rate and tidal volume, thus, leveling the isocapnic fluctuation pattern of breathing. Important to note in- dicators of pulmonary ventilation, which in all subjects exceeded the value of the physiological norm. Obviously, a sufficiently high level of ventilation at this age should be regarded as the manifestation of age structural and functional changes. However, breathing pattern characterizing ventilation in general is somewhat different in women with different ventilatory capacity. Women are the first group match the type of breathing pattern – bradypnea. In women of the second and third groups breathing pattern is of the normopnoea type, but with high values of depth of breathing. Also identified features of the mechanics of breathing and the fac- tors contributing to its change, lead to the development of pulmonary risk.

Grabovskaya E. Correction of non-specific adaptation reactions of athletes by means of ultra-high frequency electromagnetic field (UНF EMF)
Abstract. The effect of ultra-high frequency electromagnetic field (UНF EMF) on the development of adaptive reactions of the body and the functional state of the sympathetic nervous system of athletes of different specializations. It is shown that in all three groups of subjects under the influence of UHF EMF has changed the initial level of adaptive reactions of the body, and to the course of UHF reaction reactivation was detected in 50-67 % of cases in all groups surveyed. After 10 sessions of UHF-therapy, depending on the group of subjects, the reaction reactivation fixed in no more than 17-33%, reaction training, calm and increased activation were de- tected in 67-83% of subjects. Also, after 10 sessions of UHF-therapy in groups of athletes and students who are not involved in sports, opposite changes were observed cytochemical indicator of catecholamines in erythrocytes. Do football players and wrestlers was a transient increase followed by a decrease cytochemical indicator of catecholamines in peripheral blood erythrocytes. Students who are not involved in sports, the level of catecholamines cytochemical index gradually decreased. The daily half-hour effects of UHF EMF on biologically active point VC17 the subjects of all three groups, has led to a decrease in sympathetic nervous system ac- tivity. The degree of severity of reactions in different groups of athletes was different.

Korzh A.P. Sustaining the livelihoods of populations as a basis of the carrying capacity formation of their living environment
Abstract. Human society is a certain model for the development of the corresponding scientific understanding of the general biological laws. For an explanation of the relationship in the system “organism – environment” term “survivability”, widely used in various fields of science is quite appropriate to be involved. The term “life-support”, in our opinion, should be understood as a full realization of the organism (or other biological systems) of its vital functions. The loss of a normal reproduction, which is the most demanding to the conditions of existence, is the first sign of the deterioration in the livelihoods of organisms. The quantitative expression of the relationship of the organism with the environment is the mostly realized through a comprehensive index that takes into account a lim- iting determine impact of environmental factors. Such indicator may be a carrying capacity, which provides the possibility for the ex- istence of organisms or their aggregates of full value. The existing capacity has a peculiar pressure on the relevant group of organ- isms, which may in some way limit its different manifestations of life. Anthropogenic impact on the environment leads to the trans- formation first of all the breeding habitats, which causes the break of reproductive functions of the species populations. As a result security measures the not always give the desired effect, and an increasing number of species goes into the category of endangered. Population dynamics of any kind (or groups of individuals) under specific conditions will directly depend on the livelihoods and fluc- tuate within the available capacity of the environment. Without the proper livelihoods, manifested by a particular container environ- ment, the preservation of any natural objects is not possible. Increasing the productivity of the exploited elements of the biosphere requires a corresponding increase of their livelihoods to the possibility of all life processes realization and to expanding of the medi- um capacity. Impact on the carrying capacity of the species helps to activate microevolution processes that comply with the rule of Le Chatelier – Brown. At the same time, these processes are not only poorly controlled by man, but mostly going counter to our wishes. Human impacts predominantly acquire the form of r-selection, helping to improve the biotic potential of the species. These processes are mostly negative for the people.

Brem V.V., Buga S.P., Dmitrenko I.V. Influence of oxides of silicon and aluminum on the solubility of hydrogen fluoride-oxide melts
Abstract. One of the most significant factors that determine the strength of steels, is the content of dissolved hydrogen. Using any method of production of steel, it definitely depends on the permeability of the slag cover, that is, ultimately, on the composition of the gas phase over the system slag – metal. In addition you need to find a correlation between the composition of the fluoride oxide flux and composition of the gas phase. This factor determines the solubility of hydrogen in the melt. The final result should be the obtaining of the equations that would count the solubility of hydrogen in fluoride-oxide melts of given composition. ETC.

Ausheva N. Modeling of minimal surfaces based on isotropic curves and quasiconformal change of parameter
Abstract. The paper is proposed constructing of minimal surfaces based on spatial isotropic Bezier curves. Modeling of isotropic curves is realized in a complex space. Several methods of constructing such curves: based on analytic functions of a complex varia- ble, based on a specified real curve in the plane and based on the deformation of a plane curve in the complex space are proposed. Conditions of isotropy of the Bezier curve of the nth order are found and the curve of the 3d order is constructed as an example. A special case of constructing a Bezier curve based on isotropic sides of the characteristic quadrilateral is examined, in this case the real curve will be on the plane in three-dimensional space. The resulting curves were used as a guide curve for constructing surfaces. To create a surface the quasiconformal change of parameter in the equation of an isotropic curve is done. By separating the real and im- aginary parts we get the equations of the surfaces. The analysis of the coefficients of the first and second quadratic forms is done. It was proved that the resulting surface are minimal surfaces.

Steblyanko P., Kravchuk T. The construction of three-dimensional spline basis for solving problems of mathematical modeling
Abstract. Currently splines to date have proven themselves good enough for interpolating and solutions to various problems of mathematical modeling. This work also deals with the problem of constructing a type of spline functions, namely the construction of a three-dimensional spline basis. It provides a perspective view of a three-dimensional spline as the product of three third-order poly- nomials. The essence of the work is to find the unknown coefficients of the spline. The area of designing three-dimensional spline basis is a cube that splits into eight equivalent blocks, which in turn are divided into eight equal more pairs of equivalent parts. In the application of all conditions, including the values of the derivatives at the vertices of a cube, a system of ten equations, solving which we find the coefficients of three-dimensional spline, but depending on several parameters, which are a result of substitution in the general equation of the contract and obtain a formula of general form of three-dimensional cubic spline basis. Also in this paper we consider three separate cases, namely the case where the constant term of one of the factors in the three-dimensional spline is equal to zero, a case where two free members are zero, and when all three independent coefficients equal to zero. For each of the four cases is an example of building a specific surface formed by the base spline, and as it turned out, each individual case is the construction of the spline in different cubes of its design.

Abstract. The work deals with an experimental study of vibrations of centrifugal fire pump PN-40UV with defect. A worn-out bear- ing assembly was selected as internal defect. The vibration accelerations signals have been analyzed by their spectral structure. It was determined that the presence of the worn bearing in the pump leads to an appearance of additional harmonics with specific frequen- cies. This harmonics arises in the most dynamically loaded regime of operation – the usage of a pump filled with a water but without its filing. These vibrational symptoms of the analyzed type of hidden defects could be used in the procedures of fire pumps technical diagnostics.

Abstract. The aim of work is development of mathematical equations that describe the process of stationary heat conductivity and al- low to expect the temperature field in the cross section of environment “soil – air” at her heating by the linear pipeline sources of heat and to optimize the parameters of sources of heat. The decision of task is executed with the use of mathematical vehicle of law of heat conductivity, equations of indissolubility and methods of numeral decision of reverse nonlinear regional tasks on conformal and quasi-conformal reflections. In the derivation of mathematical equations the process of heating of piece-homogeneous environment is considered “soil-air” infinitely largenesses with the sources of heat accommodated in parallel in soil. Thus the sources of heat are in- terpreted by points. The calculation area of task is certain as a piece-homogeneous environment with the line of division on the sur- face of soil as a straight line. Soil and air environment are characterized the considerably differing permanent coefficients of heat conductivity. The sources of heat are interpreted by the points placed on identical distance in soil (on soil), and in mid air, according- ly, the flows of heat are interpreted as the symmetrically placed points. Mathematical transformations are get equations for determi- nation of values of thermal potentials and thermal streams in overhead and lower semi planes of calculation area. The equations are got for determination of height of placing of sources of heat for providing of the set temperature of air. Calculations are conducted with the use of complex of the programs of MATLAB and results are got as isothermal areas of distribution of temperatures at the different placing of sources of heat on a depth and at heating of soil by six sources of heat, placed on her surface. Offer methodology of formulation and calculation of tasks of heat conductivity in an environment “soil-air” allows to expect the temperature condition of environment and optimize the parameters of sources of heat and calculation area, and also to take into account reverse influence of descriptions of process of heat transfer on descriptions of calculation environment.

Melnik K.V., Glushko V.N. Application of Bayesian networks for data processing from medical cards
Abstract. Medical information technologies are the essential tool for solving various health problems. It is reflected in a large number of publications. Nowadays medical facilities have started to use electronic documents. There are many reasons for this: a conven- ient storage of the patient information, easy and quick access to information, increasing the efficiency of the healthcare facility in medical data processing. Using statistical information from the electronic database of patients helps to identify risk factors for vari- ous diseases in the service area. Patients don’t visit medical institutions regularly, so the diagnosis is a classification task on incomplete information. Bayesian networks are the appropriate mathematical tool to solve such problems. An overview of the application of Bayesian networks for disease diagnosis is provided in the article. Analysis of practical implementations of Bayesian networks showed the feasibility of this approach for diagnosis. Therefore, Bayesian belief networks are encouraged to apply for early diagnosis in uncertain and incomplete information from patients cards. The paper proposes a network, which helps to detect violations of the cardiovascular system. The information used to construct a Bayesian network was divided into three groups: the first group is risk factors that influence the emergence and development of certain diseases, the second group is a collection of diagnoses under consid- eration, and the third group is a doctor’s supervision, a variety of symptoms and results of laboratory or instrument-computer analyses. The article shows how to use the developed Bayesian network.

Romanko R.M., Petrakovska O.S. Methods and models of land monitoring affected by the exogenous geological processes
Abstract. Close relationship of land monitoring and monitoring of the geological environment is approved. The need to improve in- formation interaction between them within the implementation of the state environmental monitoring system is highlighted. The system of EGP indicators that should be considered in land monitoring is determined. The close relationship of the geological environ- ment monitoring and land monitoring systems necessitates the improvement of information exchange between them within the state environmental monitoring system at all levels. The combination of these information systems based on a GIS environment will significantly reduce the costs associated with the creation, operation and support of various types of users. This in turn will increase the effectiveness of management tasks to eliminate, minimize and prevent negative influence of geological processes and phenomena as on land resources in particular and the environment in general.
Keywords: land monitoring, geological monitoring, indicators and factors of exogenous geological processes.

Khryschuk S.Yu., Bespal’ko R.I. Anthropogenic transformation as a criterion of optimization of land-tenures at regional level
Abstract. In the article the regional features of land-tenure of territory of the Chernivtsi area are considered at regional level. A concept “level of anthropogenic transformation ” as important criterion of optimization of land-tenures is investigational. It is expected degree of anthropogenic transformation and her differentiation within the limits of administrative units of area. As a result of researches next conformity to law is educed such conformity to law: than greater area of type of landtenure and higher index of depth of transformation territory, that in a greater degree anthropogenic regenerate region. The most low level of anthropogenic transformation is inherent for territories of administrative district in the zone of Ukrainian Carpathians. The structure of landtenure within the limits of the investigated territory and level of anthropogenic transformation are considerably differentiated; it needs further research from the exposure of factors of such situation and by the ground of events on optimization of land-tenure. The natural ecosystems of the investigated region closely interlace with anthropogenic; such situation was folded as a result ecologically groundless mastering of territory for the conduct of industrial and economic activity, that stipulated violation of betweenness by earth of forest fund, agricultural setting, housing building.
Keywords: land-tenure, rational use, anthropogenic transformation, optimization of land-tenure, ecologically landscape approach.

Chikunov P.A. Physical and formal statement of the operative management salt producing enterprise
Abstract. Delivered and formalized in the form functional purpose of the task determine the best options of the gross output of gen- eralized products for the season (strategic planning) and a month of the season (tactical planning). These purposes are subject to the problem of determining the production program processing plant mines enterprises, taking into account the perturbations arising from the current fluctuations in market conditions and the deterioration of the equipment that enables decisions to be accompanied by a minimum costly mechanism. These functionals are different from the existing subject area and recurrent adaptation procedure that al- lows the calculation of indicators of the production program of the company for seasonal operational management. The results will enable design of DSS processing and mining enterprises two-tier structure, which helps expand the range of applications of distribut- ed control systems.
Keywords: production and processing of miner salt, order book, production costs, decision support in management, operational management.

Iushchuk I.V., Ovcharuk V.O., Vovkodav N.I., Metlov S.G. Investigation of the influence of the diameter of the saturator for the absorption of carbon dioxide in sugar production
Abstract. The main task of cleaning of the crude juice by lime and kiln gas – the maximum possible removal of various nonsugar components and receive deposit with high sedimentation and filtration performance. One radical methods to improve the filtrationsedimentation properties of deposit – before carbonation treatment. Therefore, in industrial practice, especially in foreign countries, were spread purification and where to get sludge with good sedimentation, filtration properties used predefecosaturation or previous defecation in combination with predefecosaturation. As a result of macromolecular substances and substance coagulated colloidal dispersion with simultaneous dehydration and adsorbed on the surface of the formed crystals of calcium carbonate. The Department of Computer Science (NUFT, Kyiv) work on optimization calculation process equipment intended for the absorption of carbon diox- ide with calcium hydroxide to neutralize cleansing crude juice in sugar production. For this purpose was developed a mathematical model calculation process carbonation. The first carbonation of calcium carbonate with the forming of deposit required for its isolation sedimentation and filtration properties. Resulted in a determination that the theoretical size saturator lower than those devices that are used in the sugar factories and varies from 2,5 to 2,1 meters with increasing content of carbon dioxide gas in carbonation. Saturation with carbon dioxide gas carbonation negative impact on rate of its use. With the increase of CO2 in the gas twice the efficiency of its use is reduced by 25%.
Keywords: optimization of calculation, purifying crude juice, sugar production.
