SUCCESSFUL APPLICATION OF SIGNS OF HEAT INDEX IN MAKING PROGNOSIS FOR EMBRYO DONOR COW PRODUCTIVITY
06.00.00 Agricultural sciences
DescriptionThe researches of the quality of 34 donor cows estrus detection during superovulation induction period, after Pg F2α injections were carried out. The clinical heat index was set up and applied. The clinical heat index is clinical prognostic criterion of successfulness of superovulation induction and embryo productivity. It was shown that donor cows showing signs of oestrus during 48-72 hours after Pg F2α injections had the best embryo collection qualities while certain increase of degenerated or aborted embryos and unfertilized oocytes is determined in embryo collections from cows showing signs of oestrus before or after that period

PARTICIPATION OF KALMYK TRADE UNIONS IN ENSURING WORKERS’ LABOR PROTECTION
DescriptionIn the article, we can analyze the participation of Kalmik trade unions in ensuring workers’ labor protection and safety engineering in 1970-ies. The sources of the article base are the documents of National archive of the Kalmyk Republic. The analysis of the large documental material showed that in 1970ies the trade unions began to study deeper the question of making better the conditions of work, more often raised the questions of labor protection at the meetings of workers committees, drew the community to this work. Kalmik trade unions organizations paid serious attention to safety engineering and industry sanitation, achieved such condition that the workers were completely provided with overalls, means of individual protection, they demanded absolute mechanization of hard processes, fought for high culture of manufacture. In spite of trade-union organizations of the republic did definite work about putting in order in cause of fulfillment of labor laws, the situation did not change

PHYSICAL MODELING OF ODOMETRIC COMPRESSION OF SAND
DescriptionThe odometric compression of sand with constant rate of loading (CRL) or constant rate of deformation (CRD) and continuous registration of the corresponding reaction allows to identify the effect of stepwise changes of deformation (at the CRL) and the power reaction (at the CRD). Physical modeling of compression on the sandy model showed the same effect. The physical model was made of fine sand with marks, mimicking large inclusions. Compression of the soil at the CRD was uneven, stepwise, and the strain rate of the upper boundary of the sandy model changed cyclically. Maximum amplitudes of cycles passed through a maximum. Inside of the sand model, the uneven strain resulted in the mutual displacement of the adjacent parts located at the same depth. The growth of external pressure, the marks showed an increase or decrease in displacement and even move opposite to the direction of movement (settlement) the upper boundary of the model ‒ "floating" of marks. Marks, at different depths, got at the same time different movements, including mutually contradictory. The mark settlements sudden growth when the sufficiently large pressure. These increments in settlements remained until the end of loading decreasing with depth. They were a confirmation of the hypothesis about the total destruction of the soil sample at a pressure of "structural strength". The hypothesis of the "floating" reason based on the obvious assumption that the marks are moved together with the surrounding sand. The explanation of the effect of "floating" is supported by the fact that the value of "floating" the more, the greater the depth

Description
The article defines types of functional stability of reproduction processes. We have proved the need of identification of interrelations between factorial and productive signs, their nature and extent of influence by types of stability (eco-economic, technological-economic, financial and economic) and efficiency (eco-economic, technological, economic). The generalized characteristic of the models and methods used for detection of dependences of the functional interrelations and interferences determining functional stability and efficiency by stages of reproduction process is given. Eco-economic stability of system is provided when the balanced coherence of interrelations and interferences in the optimum range is observed: "ability of self-reproduction – anthropogenous loading", or "an initial (standard) state – resource expenses – compensations", on each element of reproduction processes. Technological and economic stability is formed by an optimality of interrelations "process efficiency – productional effectiveness"; "productional effectiveness – economic efficiency" which allow to determine parameters of rational sufficiency of realization of productional potential of plantings and size of expenses of the economic resources providing the set reproduction level. Level of realization of reproduction potential of structural elements of an agroecosystem in comparability to the level of technogenic loading is determined by each element of an agroecosystem by the empirical and statistical method allowing to give a statistical assessment to the importance of the revealed dependences and to verify the received results. The regression models characterizing interferences of the factors influencing the level of eco-economic, technological - economic and financial and economic stability of reproduction processes are constructed

CHRONOLOGICAL STUDY OF CONFIGURATION OF A WATER – BOILED PROTEIN SYSTEM WHEN DRYING
DescriptionThe article presents results of research on drying a slurry consisting of distilled water and finely chopped cooked chicken protein of table eggs. The suspension is placed in a Memmert oven, which has temperature of 60 °C. In the process of removing moisture when drying the slurry of water - boiled protein we examined kinetics of its drying and performed chronological photographing of conformation of the system of water - boiled protein. The final weight of the protein remaining after evaporation, was 0.06 g corresponding to 26% by weight of cooked protein source in an amount of 0.23 g. The analysis of the system appearance including the evaporation of the water showed that the protein was originally white, and this color does not undergo any changes until 35 minutes of drying, i.e. when the main base is water. Upon further drying of the suspension, starting with 40 minutes, boiled protein literally "melts" in the surrounding water residues; and as it is disappearing, becoming more and more transparent. Meanwhile, the forms of the protein are becoming round and transforming into the form of liquid crystals. The final phase of the protein is a solid transparent film
