Lyzogub V.S., Chernenko N.P., Kozhemyako T.V., Dziuban I.O. Individual reactions of cerebral hemodynamics and heart rate during mental activity with high rate of information presentation
Abstract. Analysis of parameters of heart rate variability (HRV), wave structure of heart rate (WSHR) and cerebral hemodynamics (CH) during differentiation and information processing at high rate of its presentation allowed to distinguish three types of indi- vidual reactions dependent on functional mobility of nervous processes (FLNP). Normoreactive type of reaction determined in 61% of subjects with high FLNP was characterized by optimal and coordinated reaction of intracranial vessels tonus and systemic sym- pathicoadrenal mechanisms of heart rate regulation. Another type, hyperreactive, was determined in 63% subjects with low FLNP. This type of vegetative support control of mental activity was characterized by marked activation of systemic sympathicoadrenal and minor activation of regional control mechanisms. The third type of reaction, hyporeactive, was characterized by minor changes of regional and absence of compensatory reactions of systemic control mechanisms and was detected in 6% of subjects with high FLNP and in 10% of subjects with low FLNP.

Bogdanovskaya N.V., Malikov N.V. Evaluation of Dynamics of Changes in Different Ways Arginine Metabolism Activity under Adaptation 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.

Barkáts N. Anomalies of palmaris longus muscle, their significance in medicine, the use of muscle in surgery
Abstract. The palmaris longus is one of the most variable muscles in human body. Its variability was caused by the loss of anatomi- cal and physiological function it had in the primates, during the evolution of human hand. Though the muscle lost its function, this function loss made it an important muscle in plastic and reconstructive surgery as the most frequently used tendon donor. Also this function loss made it an important muscle in medicine and surgery, since different variations of palmaris longus may cause various pathological processes. Most frequently nerve inflammation, caused by nerve compression by an anomalous variation of palmaris longus muscle. The described above features made the palaris longus a frequent subject of the anatomical, morphological, and physi- ological studies.

Kurtyák Á., Csoma Z. Spatial changes in water quality of Verka-channel
Abstract. Our research is based on the water quality measurements of the Vérke canal which flows from south-east to north-west in the Beregszász district. Our results may contribute to a deeper understanding of the problem, since very few investigation dealt with this topic. Unlike previous researches we can form a much more detailed picture of the ecological state of the canal, as the area of the research covers the whole length of the Vérke. According to the results in some sections several water quality parameters crossed the official Ukrainian permissible limits. The field works confirm that it is caused by strong anthropogenic effects such as: communal wastewater and dissolved salts from thermal baths. The serious problem is that in Beregszász the sewage network has a coverage of 40% only and due to the lack of the proper drainage system and the appropriate use of thermal water the problem is still unsolved.

Zubchenko S. Prognostic value of regulatory T lymphocytes in Epstein -Barr virus infection
Abstract. It was conducted a comprehensive clinical and specific immunological study of the 52-patients in order to assess the num- ber of regulatory T cells in different stages of chronic Epstein-Barr virus (EBV) process. On the basis of polymerase chain reaction (PCR) in 48,1% of patients revealed EBV DNA, indicating that EBV infection relapse with replicative activity of the virus which was confirmed by high titers of specific EBV-VCA-IgG+ and clinical manifestations. In 51.9% of patients chronic EBV infection in a latent stage was verified on the basis of availability of EBNA-IgG+ and low titers of specific EBV-VCA-IgG + amid a lack of DNA EBV. It was determined that patients with EBV-infection in a replication step the absolute number of T-reg-cells (CD4+/CD25+) were significantly lower (0,34 0,08 g/l, p <0,05) in compression with with patients in latent stage (0,47±0,09 g/l) and healthy people (0,50 0,16 g/l), which may be a predictor of forming an autoimmune or allergic disease.

Dulo O.А., Furman Y.M. Study the level of physical health of young men of mountainous area transcarpathia by the meta- bolic level of aerobic productivity of providing of energy
Abstract. The work is devoted to the study of the level of physical health of young men of the age of 17-21, which are living in the mountain area Transcarpathia. Level of physical fitness was assessed for indicators of aerobic efficiency, namely determined physical productivity, maximum oxygen consumption, using the method veloergometry. To assess the level of aerobic productivity and use the scale Y.P. Pyarnata. We surveyed young men using the method Heath-Carter somatotype determined conditionally distributed them into five groups: with endomezomorfic somatotype, mesomorphic somatotype, somatotype mezoektomorfic, ectomorphic somatotype and balanced somatotype. The greatest number of young men identified with endomezomorfic somatotype (33,9 %), with minimal ectomorphic somatotype (4,8%). The level of aerobic efficiency, which displays the physical health of the young men with endomezomorfic and balanced somatotypes correspond to the level “below average” and the relative performance of maximum oxygen consumption in mountain young men somatotype these are below the “safe level of health” and constitute 39,1±0,93 ml∙min-1∙kg- 1 and 41,6±2,13 ml∙min-1∙kg-1, respectively. Average values VO2 max rel. mesomorphic, mezoektomorfic and ectomorphic somatotypes meet the “average” level of aerobic productivity and the level of physical health of these young men somatotype corresponds to the “safe level of health”. Significantly the lowest average values VO2 max rel. observed representatives mountain endomezomorfic soma- totype (p0,05). The highest average values of VO2 max rel. representatives have ectomorphic somatotype – 45,8±1,48 ml∙min-1∙kg-1 and mezoektomorfic somatotype 43,3±1,29 ml∙min-1∙kg-1, and was significantly different from other somatotypes 14,6 %, and 9,7 %, respectively (p0,05). Average values of VO2 max rel. young men mountain with mesomorphic, mezoektomorfic, ectomorphic and balanced somatotypes among themselves were not significantly different (p>0,05).

Brem V.V., Kozhukhar V.Ya, Savich S.L., Buga S.P., Dmitrenko I.V. Electrochemical doping of remelted steels by hydride elements
Abstract. The task of obtaining high quality steela is not always achieved in ussual steel-melting aggregates of traditional metallur- gy. In this connection the methods of additional treating of ready steel are intensively developed. One of such methods is the method of electroslag remelting (esr). However, the practical usage of this method, both in metallurgical and machinery industry, has revealed that in some cases the electroslag remelting of steels is accompanied by significant additional hydriding. This circumstance is still holding back widespread usage of esr method for remelting of many structural alloy steels with increased flakes sensibility (i.e, a tendency to form hydrogen cracks – so-called flakes). In the work the relationship between the degree of destoichiometrization of flux melts АНФ-6 and АНФ–32 and flakes sensibility of remelted steel 15Х3НМФА in the molten state in industrial conditions is evaluated. Given the forms of existence of hydrogen in iron the original method (by the parameter Фн) of quantitative assessment of flakes sensibility of structural steels was developed. In the production conditions the effect of degree of reduction destoichiometriza- tion of fluxes АНФ-6 and АНФ-32 (defined by incorporation of different amounts of cerium or aluminum) on flakes sensibility of remelted steel 15Х3НМФА in the molten state was studied. It was established that additive of reduces to fluxes in an amount of 0.08 … 0.16 wt. % allows to reduce flakes sensibility of steel 2 … 3 times as compared with the esr processes in usual fluxes. It was also found that at equal powers of destoichiometrization the specificity of this effect depends on the composition of the flux. With the results of experimental melts with the introduction in the original slag melts (based on flux АНФ-6 and АНФ-32) of fluoride СеF3 and cerium during the esr it was confirmed that flakes sensibility of remelted structural steels (15Х3МФА and 40ХН) is determined by the residual content of cerium in them. However, this relationship has clearly expressed minima, whose position is due to both the composition of remelted metal, and the composition of the used flux.

Brem V.V., Kozhukhar V.Ya, Savich S.L., Buga S.P., Dmitrenko I.V. Desorption of hydrogen from fluxes of fluoride-oxide systems
Abstract. Thermal decontamination of industrial granular fluxes in the mode of continuous rise of the temperature is a sequential series of stages of thermal degassing of different forms of existence of hydrogen in them. In accordance with the requirement of ensuring of full desorption of hydrogen from the fluoride-oxide fluxes of ESR the limiting stage of the process of thermal degassing is the last stage. This stage corresponds to the area of maximum temperature of degassing. It is established, that in this temperature range specified for each brand of flux, from the fluxes highlight dissolved in them hydrogen-containing gases. Taking into account the thermodynamic characteristics of dissolution of hydrogen in the fluoride-oxide melts and taking into account features of industri- al technology of smelting and granulation of fluxes of ESR from the latter must be released during thermal desorption, mainly, such hydrogen-containing gases, as H2O, HF, HCl and H2. Investigation of kinetics of thermal dehydration and degassing of hydrogencontaining compounds from the granules of fluxes of different sizes have shown that the relative distribution of hydrogen of different forms of its existence (crystalline, hydroxides and dissolved hydrogen) for this brand is approximately the same for all factions. Dissolved in phase components of the fluxes hydrogen-containing gases produce at temperatures higher then 650…700 °C. The limit- ing stage of the multi-stage process of thermal degassing of the fluoride-oxide fluxes is the desorption of dissolved hydrogen- containing gases from crystalline and glassy phases of granules. With the help of the kinetic curves of thermal desorption of hydro- gen in the isothermal mode for fluxes of different brands a degree of desorption of hydrogen at different temperatureswas defined.

Eraizer L.N., Ivanchenko L.V. Halurgical processing of potash polymineral ores by a method of sulfate leaching of circulat- ing solutions based on shenit
Abstract. By the existing technology the leaching of potassium-containing minerals from the crushed ore lead selectively by circulating solutions saturated in sodium chloride. The bulk of halite, however, remains in a heap and outputs together with gravel – clay fraction and sparingly soluble potassium-containing minerals (langbeinite, etc.) from the process. This leads to loss of valuable raw materials and creates environmental problems associated with the formation of waste tonnage. In this regard, an important and urgent task is to develop new technical solutions for the implementation of an integrated waste-free processing of the PMO. These include the method of ore leaching by a sulfate solutions. Unlike conventional technology of chlorine leaching in this method extraction from the ore of all soluble minerals including halite is carried. The resulting brine is processed to a potash, sodium chloride and magnesium chloride in the usual way. The remaining depleted cake containing gravel-clay fraction and insoluble potash minerals serves as a long-acting potash fertilizer with trace elements. By the same way all the components of the ore are disposed. By the results of studies on the salt, water and soda projections of called system was constructed a flow chart of the process that reflects specificity of sulfate ore leaching by the solutions of shenit and extends the knowledge of the physico-chemical metric charts. The technological scheme of moderniza- tion of the main reactor process with the maximum use of existing equipment, which is suitable for processing of the backlog halite- langbeynit dumps was developed.

Borkach E.I., Ivanitsky V.P., Kovtunenko V.S. Amorphous state in the substance hierarchy classification
Abstract. It is justified that the amorphous state are such substances, which are realized in the solid area of the phase diagram. At the same time ordered or disordered by a particular physical parameter can be any aggregate state of matter. Therefore, solid state combines two large classes of substances: ordered solids (mostly crystals) and disordered solids (or amorphous). It is shown that the main parameters of this separation are the geometric characteristics of the spatial arrangement of the particles of matter among themselves, which defines a topological order of the solid. Thus, the terms “disordered” can be applied to any state of matter, and the term “amorphous ” – only for solid systems.
