Turkish policy in the South Caucasus
Authors: Suvanova M. S.
Published: August 2018

The South Caucasus region traditionally has an important role to play in global politics. This region for centuries has been an arena of confrontation for geopolitical and geostrategic interests between regional states and world powers; this affected the main transport routes, different cultures and religions. With the collapse of the USSR, the South Caucasus became an important and strategic place for Western countries; this bolstered the weakening of Russian influence in the region and the creation of a catalyst for further strengthening of its partners. Western countries sought to establish control over the extraction and diversification of Azerbaijani hydrocarbons. To fulfill these goals Western countries have relied on their ally Turkey, which also pursues its interests in the South Caucasus region.

Since the early 1990s, Turkey’s policy towards the countries of the South Caucasus has intensified. Turkey developed policies of expanding its influence in the region. These policies were complex; it included both economic, energy and cultural components. A key element of Turkey’s policy in the region was the energy aspect. In the issue of diversifying the energy resources of the South Caucasus Turkey has made significant progress by implementing projects of pipelines going through its territory, she achieved the status of an energetic conveyor. Another important area of Turkey’s policy in the South Caucasus was the cultural and educational aspect. It is based on the policy of «neo-Ottomanism», which includes elements of «pan-Turkism». The main purpose of this idea was to expand Turkey’s influence by educating pro-Turkic youth in the countries of the region, and also create a positive image for Turkey among various segments of the population that would support its policies.

The peculiarity of Turkey’s policy is a multilateral and flexible policy that includes both economic integration, energy cooperation, and a soft and effective policy that includes cultural interaction based on ethnic and linguistic similarity.
Modern hydro-energy problems in Central Asia
Authors: Zakharova K. S.
Published: August 2018

One of the most complex problems for Central Asia is scarcity of fresh water and related transboundary water-sharing. The current situation is the result of countries` economic policy, lack of regional engagement on water use, global climate change, population growth and increased consumption of water resources, what has already influenced on reducing water availability.

Feature of Central Asian drainage system is extremely uneven distribution of water resources not only throughout the region, but also throughout each country, what does not let republics take full advantage of water resources in its ensuring of the national interests. The major water sources of the region located on the territory of two countries as Kyrgyz Republic and Republic of Tajikistan, what causes difficulties in relations of these countries with Republic of Kazakhstan, Turkmenistan and Republic of Uzbekistan. Furthermore, situation is compounded by different approaches of Central Asian countries to water use.

Since the early 1990s, water issues became a factor of regional security. The potential of conflict in current mechanisms for water distribution is notably high, that is why water issues one of the priorities on the list of Central Asian problems and requires constant monitoring. Despite many discussion and attempts to resolve regional water problem, the sides have not come to an agreement. Involvement of other countries and international organizations in development of water problem solution has not been successful.

With the election of a new President of Republic of Uzbekistan, there have been a warming of relations in the region and trend towards joint policy-making with respect to Central Asian development. That could have a positive impact on the situation with hydro-energy resources.

Published: August 2018

In this paper, we present our new computer program, D+, which uses the reciprocal-grid (RG) algorithm to efficiently compute X-ray scattering curves from solutions of complex structures at high-resolution. Structures are defined in hierarchical trees in which subunits can be represented by geometric or atomic models. Repeating subunits can be docked into their assembly symmetries, describing their locations and orientations in space. The scattering amplitude of the entire structure can be calculated by computing the amplitudes of the basic subunits on 3D reciprocal-space grids, moving up in the hierarchy, calculating the RGs of the larger structures, and by repeating this process for all the leaves and nodes of the tree. For very large structures, a Hybrid method can be used to avoid numerical artifacts. In the Hybrid method, only grids of smaller subunits are summed and used as subunits in a direct computation of the scattering amplitude. D+ can accurately analyze both small- and wide-angle solution X-ray scattering data. We present how D+ applies the RG algorithm, accounts for rotations and translations of subunits, processes atomic models, accounts for the contribution of the solvent as well as the solvation layer of complex structures in a scalable manner, writes and accesses RGs, interpolates between grid points, computes numerical integrals, enables the use of scripts to define complicated structures, applies fitting algorithms, accounts for several coexisting uncorrelated populations, and accelerates computations using GPUs. D+ may also account for different X-ray energies to analyze anomalous solution X-ray scattering data. An accessory tool that can identify repeating subunits in a protein data bank (PDB) file of a complex structure is provided. The tool can compute the orientation and translation of repeating subunits needed for exploiting the advantages of the RG algorithm in D+. In addition, a python wrapper is also available, enabling more advanced computations and integration of D+ with other computational tools. Finally, we present a large number of tests and compare the results of D+ with other programs when possible and demonstrate the use of D+ to analyze solution scattering data from dynamic microtubule structures with different protofilament number. D+ and its source code are freely available (https://scholars.huji.ac.il/uriraviv/software/d-software) for academic users and developers.
Molecular Level Interpretation of Vibrational Spectra of Ordered Ice Phases
Authors: Moberg Daniel R. , Sharp Peter J. , Lab Paesani
Published: August 2018

We build on results from our previous investigation into ice Ih using a combination of classical many-body molecular dynamics (MB-MD) and normal mode (NM) calculations to obtain molecular level information on the spectroscopic signatures in the OH stretching region for all seven of the known ordered crystalline ice phases. The classical MB-MD spectra are shown to capture the important spectral features by comparing with experimental Raman spectra. This motivates the use of the classical simulations in understanding the spectral features of the various ordered ice phases in molecular terms. This is achieved through NM analysis to first demonstrate that the MB-MD spectra can be well recovered through the transition dipole moments and polarizability tensors calculated from each NM. From the normal mode calculations, measures of the amount of symmetric and antisymmetric stretching are calculated for each ice, as well as an approximation of how localized each mode is. These metrics aid in viewing the ice phases on a continuous spectrum determined by their density. As in ice Ih, it is found that most of the other ordered ice phases have highly delocalized modes and their spectral features cannot, in general, be described in terms of molecular normal modes. The lone exception is ice VIII, the densest crystalline ice phase. Despite being found only at high pressure, the symmetry index shows a clear separation of symmetric and antisymmetric stretching modes giving rise to two distinct features.
QUANTITATIVE METHOD OF ESTIMATE OF AERODROME BIRDS HAZARD RISK
Authors: Yudkin V. A. , Grabovski M. A.
Published: August 2018

The formalized parameters of bird hazard assessment at the aerodrome are presented. The size of total biomass of all birds that are in a zone of aircraft movement reflects the aggregate characteristic of ornithological hazard. This is a dynamic parameter, its dimensionality is kg/hour‧km2. The size of biomass is differentiated on high-altitude layers and the directions of its movement. In addition, it is necessary to estimate activity of each bird species at the aerodrome as component parts of bird hazard. Its dimensionality is individuals/hour‧km2. One more parameter of aerodrome bird hazard in the assessment process of activity of each bird species is the behavior pattern of birds in aerodrome airspace. This parameter will allow to reveal the sources of bird arrivals at the airfield and to detect the causes of it. Assessment of this share is necessary to choose the effective measures to decrease bird strike risk. The birds recording technique at airfield has been designed to obtain quantitative values of main parameters of bird hazard. The birds recording is carried out from the observation points located on the opposite sides of the runway. The birds recording technique is based on visual detection of birds, identification of species, sex and age determination, expert estimate of altitude and direction of their movement. Except the flying birds, the foraging and resting birds on the ground are also considered. The contribution of these birds to the aggregate value of ornithological hazard is bigger than overflying birds. The birds recording technique is described in detail. The norms and frequency of birds recording to obtain data on daily and seasonal dynamics of aerodrome bird hazard are substantiated. The algorithm of processing the results of birds recording and calculation of the main parameters value of bird hazard is stated. Gradations of bird hazard and relevant measures to decrease quantity of birds at airfield are proposed.
Parallel mathematical models of dynamic objects
Authors: Voliansky Roman , Pranolo Andri
Published: August 2018

The paper deals with the developing of the methodological backgrounds for the modeling and simulation of complex dynamical objects. Such backgrounds allow us to perform coordinate transformation and formulate the algorithm of its usage for transforming the serial mathematical model into parallel ones. This algorithm is based on partial fraction decomposition of the transfer function of a dynamic object. Usage of proposed algorithms is one of the ways to decrease calculation time and improve PC usage while a simulation is being performed. We prove our approach by considering the example of modeling and simulating of fourth order dynamical object with various eigenvalues. This example shows that developed parallel model is stable, well-convergent, and high-accuracy model. There is no defined any calculation errors between well-known serial model and proposed parallel one. Nevertheless, the proposed approach’s usage allows us to reduce calculation time by more than 20% by using several CPU’s cores while calculations are being performed.

Published: August 2018

O estudo objetiva analisar se há conflito entre direito ao conhecimento da ascendência biológica e direitos da personalidade (anonimização ou confidencialidade de dados) do doador do material biológico humano armazenado em biobancos, consoante o §3º do art. 17 do Provimento do Conselho Nacional de Justiça n. 63/2017. A relevância do problema é evidente porque o tema estudado carece de regulamentação legal e envolve o embate de interesses próprios de sujeitos vulneráveis. A pesquisa é jurídico-teórica, sobretudo bibliográfica. Como resultado, conclui-se que o conhecimento da ascendência biológica pela criança gerada por técnicas de reprodução humana assistida não viola os direitos da personalidade do doador.
Balancing Graduate School and Mothering: Is There a Choice?
Authors: Prikhidko Alena , Haynes Cliff
Published: August 2018

Aim/Purpose: Multiple emotional and cognitive resources are needed for graduate students to overcome stress associated with balancing studies and personal life. This research aimed to explore the difficulties, which graduate student-mothers face while balancing school and parenting, and describe mechanisms of the balancing process.

Background: Graduate student-mothers need to structure their time so that they can equally distribute their energy between their children and graduate school work. Mothers face challenges in balancing graduate school and parenting, making choices between school and family responsibilities. This paper addresses the perceptions and experiences of graduate student-mothers who navigate coping with multiple role responsibilities.

Methodology: Researchers conducted semi-structured interviews with eight graduate student-mothers who studied at a research-intensive university. Thematic analysis was used to explore the process of balancing graduate school and mothering.

Contribution: In this paper we describe the mechanisms of the balancing process among graduate student-mothers and lay a foundation for the future research on coping strategies utilized by this population.

Findings: Student-mothers may perceive balancing graduate school and mothering as a challenge, feeling guilty for not spending enough time at school and with their children, and experiencing stress choosing between school and mothering responsibilities. The coping mechanisms for balancing graduate school and parenting roles are compartmentalization, changing behavior, and changing thoughts.

Recommendations for Practitioners : Graduate student-mothers could benefit from specific psychotherapeutic services within their institutions, learning to deal with the stress of balancing graduate school and mothering. Compartmentalization is a balancing mechanism that mothers may learn to use in counseling, separating life experiences of school and family in their mind and preventing feelings from one area of life – graduate school – to intervene with emotions related to mothering.

Impact on Society: Current research highlights the necessity of counseling services tailored specifically for graduate student-mothers, who may have increased levels of stress due to multiple responsibilities.

Future Research: The research on the effectiveness of suggested counseling strategies should follow.
Comparative Study of Pure Mg and AZ91D as Sacrificial Anodes for Reinforced Cement Concrete Structures in Chloride Atmosphere
Authors: Murthy Yogesh Iyer , Gandhi Sumit , Kumar Abhishek
Published: August 2018

Comparative study of the corrosion behavior of pure Magnesium and AZ91D anodes in reinforced cement concrete was undertaken in the present work. The steel reinforcements were kept in contact with these anodes electrochemically in chloride atmosphere and the half-cell potential drop was observed. Bare steel reinforcements were tied to the anodes and were also kept in high chloride atmosphere to test the mechanical properties. The yield stress and ultimate tensile stress were found to decrease by approximately 50MPa while the reduction in percentage elongation is approximately 25% for reinforcements tied to AZ91D and pure Mg at the end of 80 days compared to fresh steel reinforcement. The rate of corrosion of pure Mg was reportedly slightly higher compared to AZ91D due to the presence of inter-metallics as inferred through micro-graphs.

Authors: Amhudo Rasyiid Lathiif , Tavio Tavio , Putu Raka I Gusti
Published: August 2018

Concrete is the most widely used construction material in the world. Along with the increasing economic needs in the development of construction, precast technology has become a primary solution that leads to the industrialization. The use of precast concrete system offers several advantages, such as rapid erection, higher product quality, lower project cost, better sustainability, and improved occupational health and safety. In general, there are two casting methods used in concrete placement, namely wet- and dry-castings. The dry-cast concrete has also been used for its advantages particularly in precast concrete industries, e.g. its rapid hardening time for fast mold removal (it significantly increases the plant productivity). The use of Portland Pozzolana Cement (PPC) as a replacement to Ordinary Portland Cement (OPC) has become increasingly popular for the past decade. Hence, its application in dry-cast method needs to be further investigated for its mechanical properties such as its compressive and splitting tensile strengths. An experimental work was carried out to examine the properties of dry-cast concrete using both types of cements (PPC and OPC). The development of its compressive strength was also monitored at 1, 7, 14, 21, 28, and 56 days of age. The splitting test was conducted to describe the tensile strength of dry-cast concrete. The observation of crack and failure behaviour of all concrete specimens were also carried out.

Published: August 2018

The high demand of tensile strength in concrete is always a critical issue for engineers, as 10% of the compressive strength is not sufficient to withstand higher loadings. Lesser ductility and strain capacity is another major issue of normal concrete. In the queue of modern researches, this paper is an attempt to study Engineered Cementitious Composite (ECC) from research of Professor Victor Li, the University of Michigan. ECC is an ultra-ductile cementitious composite which is highly crack resistant, with a high tensile strain capacity over that of normal concrete. The composite replaces coarse aggregates and fine aggregates by sand and fly ash respectively. ECC is made up of OPC, sand (passing from 250 µm and retained on 150µm), Fly Ash (Class F) with addition of Polypropylene fiber on different percentages i.e. 0%, 0.25%, 0.5%, 0.75%, 1.0% were studied. Tensile Strength of ECC was measured by casting & testing cylinders of 4”x 8” in Universal Testing Machine (UTM). The experimental results revealed that 111.40% increment in tensile strength was found at 0.5% PP fiber at ECC 1:1:1 and an increment of 74.74% was observed at ECC 1:0.8:1.2 at 1% PP fiber. The study concludes that this composite could substitute the normal concrete where high tension is the ultimate requirement with higher strain capacity.
Effect of Cyclic Stress Level and Overconsolidation Ratio on Permanent Deformation Behaviour of Clayey Subsoil
Authors: Sun Lei
Published: August 2018

This paper presents the results of a series of one-way cyclic triaxial tests carried out to investigate the role of cyclic stress level and overconsolidation ratio (OCR) on the permanent deformation behaviour of saturated clayey subsoil during long-term cyclic loading. Based on the test results and shakedown concept, two cyclic threshold deviator stress ratios can be defined: the plastic shakedown limit cyclic deviator stress ratio CSRpt (0.46) and the plastic creep shakedown limit cyclic deviator stress ratio CSRpc (0.75). It was found that, below CSRpt, the soil experiences slight deformation and gradually achieves a long-term steady state response. Within the range of CSRpt<CSR<CSRpc, the plastic strain will accumulates substantially and becomes unstable. Once the CSRpc is exceeded significant deformation and failure may occur. In the practical engineering, CSRpt can be used for preliminary design of pavement foundation. In addition, based on the test results, a simplified permanent axial strain model that explicitly considers the effects of CSR and OCR is developed.

Authors: Luo Xiaoyu , Zhang Chong , Xiong Shishu , Liu Zhenqing
Published: August 2018

The downburst is an extreme weather condition whose resulting load will affect the stability of the building structures. The characteristic of downbursts is required during the design of buildings. In order to achieve the characteristics of the downbursts, large eddy simulation (LES) is adopted. The method impinging jet is used to reproduce the downbursts, meanwhile smooth and rough ground conditions are examined. The setting of the rough layer of the ground is done by using the immersion boundary method (IBM). After the simulation, the wind field is decomposed into the mean component and the turbulence component. In this paper, the radial wind speed profile and the wind speed time diagram of the simulation experiment are compared with the previous measured data and the simulation results. This paper reveals that the radial wind speed is the key part of the downburst wind speed, and it rapidly increases with height. It is also found that the rough ground will cause the peak radial velocity to move up, which is consistent with the change of the main annular vorticity in vortex cloud image analysis. Finally, the turbulence intensity is found to be relatively small at the position where the radial wind speed is relatively large.

Published: August 2018

The paper builds a physical model of testing in the laboratory with the parametric tempered glass box 0.5  0.5 1.2 m (length  width  depth) containing saturated clay to study the settlement and consolidation when loading increased gradually over time. The research covers herein to present the monitoring of settlement and pore water pressure, settlement calculation, numerical simulation using PLAXIS software V8.2 based on the results of soil physical and mechanical tests before and after loading in case of having or not prefabricated vertical drain (PVD). In case of no PVD, the calculation and numerical simulation using the soil parameters before loading have the differential settlement from the monitoring data, approximately 3.86 mm (10.45%), 0.41 mm (1.11%) respectively. Meanwhile, the deviation in the case using data after loading is about 2.29 mm (6.20%), 0.21 mm (0.56%) respectively. In case of PVD, the calculation and numerical simulation with the testing result of before loading deviation from the settlement monitoring by subsidence meter is 2.91 mm (7.88%), 44.42 mm (120.28%), calculation and simulation with the testing result of after loading deviation is 0.80 mm (2.17%), 1.26 mm (3.41%). In the case of having PVD, the difference in calculation, subsidence observation, and numerical simulation between the mechanical properties before and after loading is significant, when using the mechanical data after loading then the results are quite close to the subsidence of observation and simulation rather than before loading.
An Enhanced Hybrid MobileNet
Authors: Chen Hong-Yen , Su Chung-Yen
Published: August 2018

Complicated and deep neural network models can achieve high accuracy for image recognition. However, they require a huge amount of computations and model parameters, which are not suitable for mobile and embedded devices. Therefore, MobileNet was proposed, which can reduce the number of parameters and computational cost dramatically. The main idea of MobileNet is to use a depthwise separable convolution. Two hyper-parameters, a width multiplier and a resolution multiplier, are used to the trade-off between the accuracy and the latency. In this paper, we propose a new architecture to improve the MobileNet. Instead of using the resolution multiplier, we use a depth multiplier and combine with either Fractional Max Pooling or the max pooling. Experimental results on CIFAR database show that the proposed architecture can reduce the amount of computational cost and increase the accuracy simultaneously.

Published: August 2018

The aim of this work is to develop an intelligent optimization software based on enhanced VNS meta-heuristic to tackle Vehicle Routing Problem with Simultaneous Pickup and Delivery (VRPSPD). An optimization system developed based on enhanced Variable Neighborhood Search with Perturbation Mechanism and Adaptive Selection Mechanism as the simple but effective optimization approach presented in this work. The solution method composed by combining Perturbation based Variable Neighborhood Search (PVNS) with Adaptive Selection  Mechanism (ASM) to control perturbation scheme. Instead of stochastic approach, selection of perturbation scheme used in the algorithm employed an empirical selection based on each perturbation scheme success along the search. The ASM help algorithm to get more diversification degree and jumping from local optimum condition using most successful perturbation scheme empirically in the search process. A comparative analysis with a well-known exact approach is presented to test the solution method in a generated VRPSPD benchmark instance in limited computation time. Then a test to VRPSPD scenario provided by a liquefied petroleum gas distribution company is performed. The test result confirms that solution method present superior performance against exact approach solution in giving best solution for larger sized instance and successfully obtain substantial improvements when compared to the basic VNS and original route planning technique used by a distributor company.

Published: August 2018

Raising of economic efficiency and sustainability of the national agroindustrial production in conditions of fast development of science, machinery and technology, high market competition, and integration processes expansion is largely conditioned by development activation, implementation and investment support of innovations. Enough attention is paid to the issues of sustainability, innovative development and investment activity in modern economic literature. At the same time, the problem of investment support for sustainable innovative development of agroindustrial complex is still studied poorly, which makes scientific research in this field relevant. Based on brief retrospective analysis, an improved understanding of the sustainable development of the agroindustrial complex, as well as in the context of its components, is proposed in the paper. It is shown that the basis for sustainable agroindustrial complex development in modern conditions is the increase of innovative activity at all the management levels. As a result of the study, a list of the main regulatory and legal acts regulating the issues of innovation activity and the privileges and incentives established by them for business entities, including agrarian ones, were systematized. The main problems preventing activation of innovative development of agroindustrial production are listed. In order to solve these problems the authors within the research framework developed a concept of investment support for sustainable innovative development of the agrarian sector, which includes eight interrelated consecutive blocks. Implementation of the proposed concept will contribute to more complete involvement of potential financing sources and their effective use in the investment activities, thereby ensuring competitiveness of the national agroindustrial complex and its sustainable development, considering interests of the current and future generations.

Breeding of new domestic varieties of economically useful plants for different purposes (food, fodder, technical, medicinal, decorative, etc.) is the basis for food, environmental and social security of the republic population. Therefore, preservation, study, mobilization and rational use of genetic resources in the context of global climate change and steady increase of anthropogenic pressure on nature is a planetary problem. The welfare and life of the present and future generations of mankind depends on successful solution of this problem. The paper presents history in chronicles of genetic resources preservation in the Republic of Belarus – from conception of this trend to the present day. Particular attention is paid to the presentation of the results obtained by the implementing organizations of the State Program “Plant Gene Pool” over a 17-year period (2000-2017), including 11 academic institutions and 2 higher educational institutions of the republic. The contribution of each organization to the national genetic bank formation is reflected. Basic, active, working, field, double, target, indicative, core and training collections of the main resource crops, economically significant crops and forest-forming species were formed by their efforts. The largest and most valuable genetic collections of 7 implementing organizations are included in the State Register of Scientific Objects, which constitute the national treasure of the Republic. These collections are a source of valuable genetic material and, at the same time, they are successfully used in scientific, environmental, educational and other programs. Currently, genetic collections in general include over 78,300.00 specimens belonging to 1,680.00 species of crop plants and their wild relatives. 1,016.00 varieties of crop plants were created based on them. The paper also reflects the main approaches and perspectives of preservation and rational use of the plant gene pool. Sophisticated and time-consuming processes of genetic collections formation in modern hard economic and regional natural conditions, taking into account the results of similar studies of other states, will serve as a scientific and information basis for increasing efficiency and improving work in this direction. In practical terms, the high level of species, variety and form biological diversity of genetic collections serves as a guarantee for their efficient use in crop production and selection as sources and donors of valuable genetic material.
MATHEMATICAL SIMULATION FOR IMPROVEMENT OF RELIABILITY OF EVALUATION OF THE FIELD AGRONOMIC EXPERIMENT RESULTS
Authors: Likhatsevich A. P.
Published: August 2018

The programming (simulation) of yield in the area of “risky farming” that Belarus belongs to according to data from a single-factor experiment considering only the food mode, can lead to unacceptably large errors in the calculations. These errors can easily be avoided by increasing the factorality of agronomic experiment by using standard meteorological data processed using mathematical model of crop yields. A mathematical model of environmental factors effect on crop yields is proposed and tested. It is shown that the accuracy of yield simulation (calculation) increases with the growing number of crop-forming factors taken into account. The possibilities of mathematical simulation allowing to switch from one-factor to multifactorial agronomic research are demonstrated, involving meteorological data characterizing the moisture and heat availability of the vegetation period when analyzing the results of the experiment as additional information. The moisture supply conditions can be characterized quite accurately by atmospheric precipitation during the vegetation period, and the heat supply – by the maximum daily air temperatures in the same period. Inclusion in analysis of additional water and heat factors of yield makes it possible not only to increase the factorality of field experiment, but also to substantially increase the conclusions validity according to the results based on the proposed mathematical model.
DEVELOPMENT OF MODE PARAMETERS OF IR IRRADIATION OF WEANERS ACCORDING TO ANALYSIS OF ANIMAL BEHAVIOUR USING VIDEO SURVEILLANCE SYSTEM
Authors: Gerasimovich L. S. , Sheyko I. P. , Kosko A. N.
Published: August 2018

The research relevance is determined by the need to reduce the energy intensity of intensive livestock production. The latter is possible on the basis of innovative methods and technical means of intelligent management of complex biotechnical systems with identification of animal behaviour and control using video surveillance systems. The paper presents the results of experimental researches of the energy efficiency of an automated infrared irradiation system for weaners with irradiation modes set according to analysis of video surveillance of animal behaviour. A sign for the location of animals along the floor area relative to a warm source – a dark infrared irradiator, was defined as an ethological sign for the analysis of animal behaviour. As a result of experimental studies, based on the video surveillance data, IR-irradiation modes were determined by statistical analysis of the ethological sign of the location of animals relative to the thermal source of IR-irradiation. These modes were recorded in the program of the microcontroller, within 20 days the experimental group of animals was exposed to IR-irradiation according to the established modes. It was determined that the developed irradiation modes ensure additional profit of 2.97 roubles per animal, including economic effect for heating of 0.89 roubles per animal. The developed IR irradiation modes for weaners exclude general heating requirement. The IKOV-1 automated plant allows to develop energy-efficient zoology hygienic modes for animals management based on data processing and video surveillance equipment using air temperature sensor in the IR irradiation area.

Published: August 2018

One of the important fields of carp breeding work is improvement of the commercial traits of created carp breeds or cross-breed commercial crosses. The main indicator determining the value of commercial fish is edible carcass yield depending on the interior (relative weight of carcass edible parts) and the exterior (high spin, ratios of head and body girth, type of scale) indices. The paper presents the results of researches on interior indicators (body parts ratio) of twoyearlings of two-breed crosses obtained from crossing of adapted fourth generation imported breeds grown in Belarus with carp lines of Belarusian selection. The edible part of carcass size varied from 60.7 % (three prim x fresinet) to 66.7% (GermançLahvinsk scaly), averaging 64.0 % in the two-breed crosses studied. Compared with the average population yield of carcass in twobreed crosses, statistically significant advantages were determined in combinations of crossing with German carp. In this regard, quite high indicators were also observed in combinations with the Yugoslav carp, where it was used as the maternal component of crosses, and in combinations obtained from crossing the Mirror Isobelin carp with a Butterfly breed. Based on comprehensive assessment of interior indicators, a number of crosses have been determined with increased nutritional value of carcasses, among which the maximum nutritional value was shown by the cross Germançthree prim. The obtained data are of practical importance for creation of industrial hybrids with attractive commercial traits.

One can obtain high yields of crops only when seeds with high varietal and sowing qualities are used for sowing. Various methods of presowing processing are used to improve the seed quality. Presowing seed treatment not only improves germination, but also eliminates seeds from pathogens, significantly increases their viability and improves young crops yield. One of the most promising ways of presowing treatment of small and irregular shape seeds is pelleting. This method helps to increase the seeds size and acquire a spherical shape, which greatly simplifies their sowing and allows to accurately observe the seeding rate. The paper presents design of a centrifugal pelleter with blade reflector, the results of studying the process of buckwheat seeds pelleting, and its best design and technological parameters are determined based on those when organic fertilizers based on humic acids were used as material for pelleting. Factors significantly affecting seed pelleting in a centrifugal pelleter with blade reflector were determined, the choice of objective function and criterion for improving the process are substantiated. A dependence describing the process of seed pelleting in a pelleter was obtained as a result of the regression analysis of the obtained results of experimental studies. The obtained results can be used in the field of crop production in agricultural production during presowing treatment of small seed crops and agricultural engineering during development of centrifugal pelleters with blade reflectors.

Increase of vegetable oils production provides for the further improvement of oily raw materials storage technology. It is known that technological quality of oilseeds is formed in close relation to its morphological characteristics, as well as peculiarities of biochemical processes inside of seeds, depending on external conditions and their development phase. The paper presents comparative results of researches of dynamics of qualitative and biochemical parameters of rape and brown mustard oilseeds with and without post-harvest ripening during storage. Research has shown that in order to produce high-quality fat-and-oil products, oilseeds must necessarily undergo the ripening process in artificial conditions, where the seeds are taken after they reach ripeness level enough for harvesting. Considering that the main period of oilseed storage is mainly destructive, seeds that have not undergone post-harvest ripening have active disintegration process even in case they are stored in perfect conditions. This process considerably reduces quality of seeds and their storage period. Based on the researches, practical recommendations were developed for post-harvest ripening and storage of oilseeds. The presented research data can be used to optimize the existing technologies of oily raw material post-harvest ripening and storage, to increase process quality of processed seeds and obtain high-quality fat-and-oil products.

In
this research, impacts of relative humidity on current parameters of solar
cells are investigated. An experimental methodology is considered in the
research. Outdoor tests are carried out for two different cell technologies,
monocrystalline (m-Si) and polycrystalline silicon solar cell (p-Si), under
various humidity conditions. Current-voltage (I-V) and power-voltage (P-V)
characteristics are achieved simultaneously for each sample, and the
relationship between the short circuit current (Isc) and relative
humidity is discussed. During the tests, cell temperature of m-Si and p-Si
sample is measured to be in the range of 22.9-36.1 and 21.2-38.9 oC,
respectively. It is unequivocally reported in literature that current
parameters are not noticeably affected by the rise in cell temperature up to 20
oC. Therefore, any deviation from the linearity between solar
intensity level (G) and Isc is attributed to the impact of relative
humidity. The tests repeated for low and moderate solar intensity levels
(257-482 W/m2) reveal that the linear relationship between G and Isc
is maintained for different humidity levels. In  this respect, the impact of humidity level on
current parameters of solar cells is found to be insignificant

Diabetic nephropathy (DN) is the most common microvascular complication that may lead to chronic renal failure in diabetic patients. Till now microalbuminuria, with its restrictions, is the early marker of DN, appeared after the disease exacerbation. Thus, new biomarkers are required to predict the early onset of DN before the appearance of microalbuminuria. The aim of this study is to investigate the possible use of uVDBP in the early prediction of DN. Fifty diabetic patients with DN and 40 diabetic patients without DN for both types of diabetes were enrolled in this study. All patients were tested for uACR, uVDBP (measured by ELISA), and blood HbA1c. The results demonstrated a highly significant elevation of uACR, HbA1c and uVDBP in diabetic patients with DN compared to those without DN. uVDBP exhibited a strong positive correlation with HbA1c and uACR in DN patients. ROC curve analysis showed a greater AUC (0.93), and cutoff value was >152 ng/ml with 94% sensitivity and 82% specificity for early detection of DN. These findings suggesting the sensitive and potential role of uVDBP in the early prediction and diagnosis of DN in type 1 and type 2 diabetes.
