Abstract. The paper represents the chronorhythmologic structure of the excretory function of the kidneys under the influence of monooxide nitrogen (NO) block a background of pineal hypofunction (PG). The obgect of the research was establishing an inter relationship between the functional condition of the PG and the synthesis of NO, us well as ascertaining the pathophysiological mechanisms of disturbances of the chronorhythmic organization of the excretory function of the kidneys. It has been established for the first time that NO is an important intracellular messenger of regulating chronorhythms of the excretory function of the kidneys. It has been demonstrated that the effects of Nω-nitro-L-arginine blocking (L-NNA) of NO synthesis depend on the functional activity of the PG. L-NNA blocking of NO synthesis under the conditions PG hypofunction results in more marked changes of the integral characteristics of chronorhythms of the principal parameters in the functional condition of the kidneys as compared with blocking NO synthesis with underlying PG hyperfunction. The changes of quantitative parameters of the chronorhythms of the excretory function of the kidneys determine the expediency of updating the methods of early diagnostics and preventing renal diseases.

O.А. Dulo Study the level of physical health of boys, which are living in mountain area of Transcarpathia by the metabolic level of anaero- bic energy ensuring
Abstract. The work is devoted to study the level of physical health of boys of the age of 17-21 which are living in the mountainous area of Transcarpathia. Level of anaerobic productivity of mountain boys is addicted to their somatotypes. Determinating the power of alactate 10-WAT and lactate 30-WAT anaerobic processes by the relative value showed us probably low level of the results of ectomorphic somatotype and high level of mezomorphic somatotype. High avarage results of MCEWabs had persons with ectomorphic 2111,4±51,2 kgm min-1 and mezoectomorphic – 2204,3±43,4 kgm min-1 somatotypes (p<0,05). Low results of MCEWrel had boys with endomezomorphic somatotype. The presence of fat in mountain boys (under hypoxic) is like ballast because they need more oxygen for oxidation this fat which cause less results of work for 1 min to boys with endomezomorphic somatotype.

V.P. Feketa, K.P. Meleha, O.S. Palamarchuk The dynamics of heart rate variability indices in healthy young persons under the influence of diaphragmatic breathing in the biofeedback mode
Abstract. The influence of deep diaphragmatic breathing in biofeedback mode using handheld computer device StressEraser (“Helicor”, USA) and without this device on heart rate variability (HRV) in healthy young men was investigated. It was established that breathing exercises lasting of about 15 minutes significantly affect the functional state of the autonomic nervous system (ANS). According to the HRV the deep breathing increases the overall tone of ANS activity and redistributed the relationship between its central and peripheral parts. The most effective influence on the functional state of ANS provides the device StressEraser.

D. Holis, E. Simon Influence of Zn on the survival rate and heart rate of guppy larvae
Abstract: Nowadays the research of different heavy metals in surface and ground waters became a crucial part of ecological researches. Because of different anthropogenic factors that caused and still cause the pollution of all aquatic systems. In our research we used different concentrations of Zn solutions (0,5 and 1 mg/l) to study the influence of Zn on the guppy (Poecilia reticulata) survival rate and heart rate. The examinations were repeated 3 times. Mineral water with optimal ion concentration was used as control solution. Our results showed that Zn influences both the survival rate and the heart rate of guppy, though the Zn sensitivity decreases with age of fish fry. Both survival rate and heart rate significantly decreased in solutions containing Zn.

O. Budko The morphostructure of Kostopil denudation plain
Abstract. Geostructural position of Kostopil denudation plain in relation to higher order morphostructures is exposed in the article. Fourth-order morphostructures is first distinguished, their detailed description is given. In particular, the morphostructures borders are described, relief’s relation with tectonic and geological structure of a plain is shown. Drawn conclusion about the role of one or another factors in morphostructures forming. Not all borders of Kostopil morphostructure is expressed identically well. On territory of Kostopil morphostructure it is possible to distinguish such morphostructures of IV order: Zlaznensko-Derazhnivska, Suska, Berestovetsko- Bazaltivska, Borshchivska, Zirnenska and Vedmedivska. Zlaznensko-Derazhnivska morphostructure is characterized by a high position of chalky sedimentations and separated from nearby morphostructures by tectonic break, that passes on a Goryn valley. Berestovetsko- Bazaltivska morphostructure agreed with the Volyn trap cover, which has a north-east direction. This morphostructure is well represent- ed in relief by declivous rises, build by volcanic rocks – basalts and tuffs. Within a bounds of Zirnenska morphostructure role of turonian deposits diminishes in relief forming. The quaternary deposits value is increases, considerable areas occupy by the reclamated bog arrays. Vedmedivska morphostructure is characterized by the presence of denudation chalky flat humps in the absolute marks of a 200-205 m. The east border of morphostructure is expressed by the crystalline breeds, coming to the Earth surface along the river valley of Sluch.

M.Yu. Skulsky, M.I. Stodilka Solar irradiance five-minute oscillations
Abstract. We examined a possible nature and a origin of the solar irradiance five-minute oscillations. Using solar observations we solved inverse radiative transfer problem and reproduced height stratification of the local and global temperature oscillations of low l in the solar photosphere. The pseudoglobal oscillations were extracted from photosphere oscillations; so we studied contribution of acoustic modes into the solar irradiance oscillations. It is shown, the latter ones originate from the scattering p-modes of low spherical harmonics on the solar granulation with the subsequent constructive interpherence.

E.I. Borkach, V.P. Ivanitsky, V.S. Kovtunenko Methods of description of the structure of amorphous substances
Abstract. Today to describe experimentally the structure of the amorphous substances the alternative methods are being sought actively. These methods must require only setting a small number of structural parameters of the atomic network easily sought experimentally. The best of such methods is the method that requires the least number of the initial a priori information about the system under study.The most of the above experimental methods are based on the use of the binary correlation functions of the mutual spatial location of atoms or other structural particles (or radial distribution function). As of today, the methods that will allow the structure of the whole macrosample to be described on the basis of the structure of its small fragments are being actively sought. The main problem of such approach is the optimal choice of the elementary minimal typical microregions of the amorphous atomic network, which demonstrate the properties that agree with the experimentally determined properties of the macrosample. The studies of the amorphous state must be based also on the clear distinguishing of the ideal disordered atomic network and its structural defects. The notion of the defective structural particles must be taken as a basis of such distinguishing. Their pointing out among the main structural particles may be based on the two conditions: a) the concentration of the defective particles must be much less that the atomic density of the substance; b) the relevant property or the physical and chemical parameter of the defective particle must lie beyond the limits of the distribution function of this property for the main structural particles.

V.A. Temnikov, A.V. Peteichuk The efficiency improvement of the permanent voice control over the ATC actions
Abstract. Security in transport, energy and other industries that use the dispatcher labor significantly depends on their actions correctness. Traffic controller’s mistakes can be caused by their being in a nervous and emotional stress that are constantly experienced in relation to high responsibility for their decisions. One of the ways to reduce the accidents number that may occur during the dis- patchers personal mistakes proposes to perform an automatic permanent control over the traffic controller’s actions during their operations. Current article describes the concepts and main stages of voice control over the air traffic controller (ATC) actions. Proposed control allows preventing staying on the ATC working place unauthorized person or ATC staying in appropriate emotional state (ES). Conclusion about violations is made by means of authentication and monitoring results of ATC. These results are based on analysis of ES informative parameters of the speech signal taken from the microphone output. Presents the study’s results of phonemes pitch frequency values of Russian language in a different words and phrases. These results justify the usefulness of monitoring by selected from ATC continuous speech key fragments which are parts of words (phrases) commonly used in the traffic controllers operation. Key speech fragments informative parameters are determined based on separate frames (during authentication by means of short-term analysis) and single phonemes (during ES monitoring) on which key fragments are segmented. Leads the principles of the subsystems construction of recognition and identification the key speech fragments from continuous speech, also developed authentication control system over the ATC actions. The work of the first mentioned subsystems is based on developed approach to the automatic words recognition in continuous speech taken into account the specific of ATC operation. Authentication subsystem is based on trained ANN to recognize the controlled persons. Grounded choices of informative parameters allow increasing the percentage of accurate authentication above 98% and significantly reduce the implementation time, which provided subsystem operation in real time.

V. Melnik, Yu. Blіnder, O. Pіskunova Mathematic–statistical analysis of morphometric characteristics of the relief
Abstract. The article deals with two methods of mathematical approximation of digital elevation models in a rectangular and spherical coordinate system. The first method offers the appliance of Chebyshev polynomials, the second – ordinary spherical functions without application of Legendre functions. The common features between these methods are orthogonality and possibility of getting the system of these functions by recurrence relations. In case of significant “noise” impact and the appearance of impropriety after Adamar, academician A. Tikhonov’s regularized solution method is offered. The effectiveness of regularization is illustrated. Probabilistic estimation of morphometric characteristics of the relief is possible on the basis of receiving hexadimensional covariance matrix and application of a simplified version through calculation of variograms and planar diagrams of anisotropy.

Abstract. The article deals with the issue of getting a cylindrical map projections of variable-metric scale and varivalent types. Variable scale projections are useful if you need to display dominance of socio-economic factors, indicators and so on. In mathematical models of varivalent projections as an arguments, besides geographical coordinates are entered additional indicators that more accurately reflects the spread of mapping phenomena, such as ecological situation, the state of urbanization and others. In solving the problems of zoning of settlements in addition to traditional maps are often used anamorfoza maps. Such maps are characterized by unusual topology, and their construction is a nontrivial task. Accordingly, this paper deals with the theory and practice of receiving such maps.
