The digestibility of four types of grain screenings, No. 1 screenings, rapeseed screenings, mixed feed oats and refuse screenings was measured with pigs, rats and sheep. For the pig diets, hammermilled screenings replaced 60% of a complete basal diet, with the exception of the rapeseed screenings, where replacement level was 10% (hammermilled) and 20% (whole). Digestibility values were determined by difference. In the rat diets screenings were incorporated to provide 1.5 g N 100 g−1 dry matter (DM) and the biological value (BV) of the protein was also measured. In the sheep diets, all screenings except rapeseed were provided as the sole dietary component, with the No. 1 feed screenings and the mixed feed oats pelleted without prior grinding and the other screenings ground before pelleting. For rapeseed screenings, incorporation in the sheep diets was at a level of 30%. For No. 1 screenings, apparent digestibility of organic matter (OMD) and nitrogen (ND) for pigs was 82.3 and 83.2%, respectively; BV for rats was 77.4%, while OMD and ND for sheep was 73.9 and 72.7%, respectively. For rapeseed screenings, OMD and ND for pigs for the hammermilled screenings were 46.1 and 50.7%, respectively, and for the whole screenings were 30.3 and 11.5%, respectively. Biological value (rats) was 80.0%, while for sheep OMD and ND it was 63.9 and 77.4%, respectively. For mixed feed oats, OMD and ND for pigs were 63.8 and 82.6%, respectively; BV (rats) was 61.1% and OMD and ND for sheep were 64.2 and 73.4%, respectively. For refuse screenings, OMD and ND for pigs were 63.8 and 65.4%, respectively; BV (rats) was 83.8%, while OMD and ND for sheep were 59.9 and 65.3%, respectively. Number 1 feed screenings are of a high nutritive value and are suitable as a grain for both pigs and sheep. Unprocessed rapeseed screenings are unpalatable for pigs with both dry matter and protein poorly utilized. With sheep, pelleted rapeseed screenings are readily accepted, and the nitrogen is well digested. If mixed feed oats are ground, protein is well digested by both species although dry matter digestibility is low. Refuse screenings appear to be suitable only for ruminant diets.

Abstract Sweet cherry is a thermophilic and whimsical crop that reacts painfully to unfavorable meteorological conditions, such as frost, drought or high humidity in the air and soil. At the same time, this crop requires a uniform supply of heat and moisture during the growing season. In the climatic conditions of the Volgograd region, stressful situations often arise that can partially or completely reduce the yield of fruit crops, especially those introduced to our region from other regions. To reduce the risk of losing the yield of fruit plantations, including sweet cherry, it is necessary to pay special attention to the choice of the variety, as well as the rootstock on which this variety is grafted. The publication presents the results of studying the influence of rootstocks on the qualitative and quantitative indicators of sweet cherry fruits, such as taste, weight, uniformity, color, and productivity. According to the results of the study in the field (in the garden), varietal-rootstock combinations were identified that have one-dimensional, crack-resistant, large fruits, while maintaining high and stable productivity. According to the results of research, it was found that the rootstock affects not only the strength of growth and the shape of the crown, but also the quality of the fruit. The most dependent of the studied varieties on the type of rootstock is Euphoria, the lowest weight of berries was observed on the rootstock VSL-1. At the same time, this rootstock has a higher percentage of resistance to cracking of the fruit. Based on the conducted research, it can be concluded that with the help of rootstock, it becomes possible to influence the quality indicators of fruits.

Daily Milk

The aim of research was to study the effect of different amounts of cobalt citrate produced by nanotechnology on biochemical processes in cows, their productivity and biological value of milk in the first two months of lactation. To achieve this goal the subsequent problems have been solved. We investigated the effect of different amounts of cobalt citrate on biochemical parameters of blood and milk of cows and controlled their average daily yield. The experiment has been conducted in 3 groups of cows (5 cows each) of Ukrainian black and white dairy cattle, analogue by body weight (590–620 kg), performance (6,5–6,8 thousand kg of milk per past lactation) and lactation (3–4 lactation). Unlike the control cows, animals experimental (ІІ) group for two months were fed by mineral supplements in the form of cobalt citrate in an amount of 19 mg Co/kg of dry matter of diet and research (ІІІ) – cobalt citrate in an amount of 34 mg Co/kg of dry matter of diet. Duration of cobalt citrate feeding of cows of research groups was 2 months. In all groups of cows the samples of venous blood were taken in preparation for feeding additives period and during 60 day of additives feeding period in order to determine the concentration of total protein, ceruloplasmin, sialic acids, hexoses bound to proteins and activity of amino transferases. The milk production has been controlled in days of sampling with the definition of daily milk yield per cow and taking an average sample for the determination of milk fat, protein, lactose, inorganic phosphorus and calcium. It has been established that the inclusion in the diet of cows of experimental (ІІ) group of mineral supplements contributed to an increase in animal blood total protein content by 11.9% (P < 0.05), inorganic phosphorus by 15.3% (P < 0.05) and hexoses bound protein by 8.8% (P < 0.05). Under these conditions milk content of inorganic phosphorus increased by 5.6% (P < 0.05) and average daily milk production increased by 4.5%. The use of mineral additives in third experimental group of animals within two months contributed to an increase in blood ceruloplasmin content by 5.1% (P < 0.05) and hexoses bound protein by 11.5% (P < 0.01). Mineral supplements promote 5.4% raise of average daily milk production and increase it to the lactose content by 0.10% (in absolute).

A peculiarity of pension relations is that the right to a pension should actually arise before the appointment of a pension, that is, before the emergence of a pension legal relationship. Insurance pensions are fully covered by this provision. This indicates not only the connection between pension and labor relations, but also that qualitative and quantitative indicators of labor should be reflected in the employee's pension rights.

Introduction. Smokes are aerosols that contain sublimating substances and condensing vapors, as well as products of chemical and photochemical reactions. In addition to solid and liquid particles, they contain gaseous products of both complete and incomplete decomposition during combustion process, as well as nitrogen and the remains of unreacted oxygen during combustion. The aerosol substance of smoke that has settled on any surface is called soot, which often acts as an object of fire-technical expertise, and the aggregate of soot particles that form zones of various configurations is called smokiness. Goals and objectives. The aim of the work is to study soot and its components for the development of a comprehensive methodology for the study of fires in determining both the focus and the cause of the fire, as well as the pathways of the spread of hazardous factors of fire at different stages of fire development. The main task of the work is to determine the dependence of the qualitative and quantitative indicators of soot and its component composition on the temperature conditions of combustion of various materials in order to establish the conditions for the course of a fire. Research methods. Field and laboratory methods for the study of soot are considered. Field methods include visual analysis of soot deposits (identifying the configuration of soot, color and intensity of the soot layer) and measuring the electrical resistance of the soot layer using a field contact probe. Laboratory methods include the method of microscopic morphological analysis, the method of thermal analysis, molecular spectroscopy and gas chromatography, which are indirect and direct methods for studying extracted organic components of soot. Results and its discussion. The modern methods of research of soot are analyzed. A scheme of laboratory methods is proposed. It allows carry out full morphological analysis, to evaluate the behavior of soot components during heating and composition of extracted components for solving the problems of studying fires. Regression dependences of the content of bituminous components on the logarithm of the electrical resistance of the soot layer were obtained, which showed that, regardless of the type of combustible material, a transition zone is observed on them, in which, with a relatively small change in electrical resistance, a significant increase in the content of bituminous components is observed. Conclusion. The paper considers an comprehensive approach to the study of extractable components of soot. The obtained dependences of the qualitative and quantitative indicators of soot and its component composition on the temperature conditions of combustion of various materials will improve the quality and level of reliability of information in the study of fires in order to determine the focus and cause of a fire, as well as the ways of spreading hazardous factors of a fire at different stages of its development. Key words: smoke, soot, extractable organic compounds, bitumen components, soot layer electrical resistance, molecular spectroscopy, Boltzmann function, fire investigation.

Russia is the largest country in the world and occupies one of the leading places on the planet in terms of natural resources, but the bulk of deposits were explored to some extent more than a quarter of a century ago, back in the Soviet era. Due to the changes in the sources of financing for the reproduction of mineral resources and geological exploration of the subsurface, qualitative and quantitative indicators are reduced by an order of magnitude, which leads to greater risks in the development of mineral deposits. Even despite the large number of scientific papers, the economic situation forces us to search for more modern and multi-parametric methods for evaluating the efficiency of mining. The article considers the main economic methods for evaluating the efficiency of mining, determines their essence and application features. On the basis of conducted analysis, disadvantages and advantages of using the studied methods were identified, and the author's interpretation of the economic assessment of efficiency of mining resources was given.
