THE RESULTS OF IMPLEMENTATION OF CATTLE EMBRYOS TRANSPLANTATION
DescriptionThe results of the analysis of the level of implementation of the method of cattle breeding by embryo transfer in an agricultural company from the Krasnodar region with a developed sector of cattle breeding. We have assessed the level of development of all stages of the method in the household, identified errors in the selection of animals and the increased value of culling donor cows and recipients, reduced duration of using recipient cows and high cost of all phases of the transplant process. We have raised a question of the need to change the criteria of economic evaluation of the results of the method

EXPANDING THE RANGE OF GLUTEN-FREE FLOUR CONFECTIONERY PRODUCTS BASED ON BUCKWHEAT AND QUINOA
DescriptionExpanding the range of flour confectionery products for people suffering from intolerance to wheat protein is relevant in the circumstances of import substitution. The domestic market of gluten-free confectionery products fully meets the demand of this category of people, which are dominated by sweet tooth children, requiring constant variety of confectionery. Therefore, the purpose of the work, which consists in expanding the range of pastry products based on buckwheat and quinoa, is relevant. The study presents a shortbread recipe based on buckwheat flour with different dosages of quinoa, a block diagram of the production and evaluation of the quality of the finished confectionery. Sensory evaluation of quality was carried out by a tasting analysis by a special system of scores: quantified indicators of quality - color, taste, smell, surface, shape and form in a break - is presented in the form of balls, followed by mathematical processing. We have defined physical and chemical indicators of quality biscuits, including moisture, alkalinity, absorption, fat and sugar content. Based on the assessment of quality of gluten-free shortbread we have set the optimal ratio of buckwheat flour and quinoa is equal to 70:30. The developed formulation will expand the range of gluten-free flour confectionery and can be adapted to the process and the equipment installed on the existing confectionery businesses

ESTIMATION AND SELECTION OF THE MOST OPTIMAL VARIANT DRAINING PONDS
DescriptionThis article gives estimation of drying (liquidation) ponds with subsequent selection of the most optimal variant. For example, ponds № 1, 2 have the calculations for the four drainage options: bottom outlet, using a mobile diesel pumping stations, through the siphon outlet, as well as the combined option of draining (via a bottom outlet and mobile pumping stations). The results of the calculation for each of the cases were examined; the article summarizes the estimated parameters, which allow to visualize and choose the most optimal variant of drying, depending on the time of evacuation

DEVELOPMENT OF ECOLOGICALLY SAFE EXPRESS-METHOD FOR QUALITY EVALUATION OF SOYBEAN LECITHINS
DescriptionThe article presents data, on the basis of which we have concluded that the oil and phospholipids contained in soy lecithins, the degree of unsaturation of fatty acids differ significantly from oil and phospholipids contained in sunflower lecithins, with differences in the degree of unsaturation of fatty acids of oil and phospholipids contained in sunflower and soy lecithins, leads to differences in the content of resonating protons, and, consequently, the level of amplitude values of NMR signals of protons of the investigated lecithins. It is established that the values of the amplitudes of the NMR signals of protons of each of the four components of sunflower lecithins differ from the values of the amplitudes of the NMR signals of protons the component of soy lecithins, which confirms the differences in the composition and content of fatty acids lecithins studied. Considering quantitative characteristic of mass fraction of substances insoluble in acetone, i.e. phospholipids, is the sum of the amplitudes of the NMR signals of protons of the third (A3) and fourth (A4) component, was built the graphical dependence of the mass fraction of substances insoluble in acetone, from the value of (A3+A4)/ASIS, % which is described by the equation (correlation coefficient R2 =0,9911) of the following form: y=0,8177x +2.52. Based on these data, we have developed a rapid method of determining the mass fraction of substances insoluble in acetone, soy lecithin, eliminating the use of toxic organic solvents, is environmentally safe, which is protected by RF patent for the invention

A CORN HARVESTER CONSTRUCTION AND CALCULATION METHOD DEVELOPMENT FOR CORN COBS SEPARATION FROM STEM
DescriptionThe article presents research results of a corn harvester device for corn cobs separation from the stalks, constructed as a separate picker. Each picker unit consists of three pairs of flat conveying belts arranged in parallel to vertical planes, namely an upper pair of conveying belts, the lower pair of conveying belts and fixed to corn harvester sweep frame, kinematically is not connected to other mechanisms and is provided with electric power with the possibility of adjusting the width of the aisle and the rapid replacement of the failed module with a spare unit in the field repairs. Picker module provides simultaneous rotation of corn ear on its axis and motion relative to the stem that reduces corn cobs defect and energy consumption for separating cob from stalk. The method of calculation of the basic design parameters of the picker module is developed

Description
The article presents results of design development and calculation methodology for corn harvesters stalks shearing mechanism constructed as a module with a storage device. According to the number of engagement rows, these modules are mounted on the sweep frame of corn harvesters. All modules have the ability to accumulate energy, the rotation of saws in which at each time point does not depend on saws rotation in other modules and they are not connected with each other and with other mechanisms. Constructive execution of corn stalks shearing mechanism with accumulation device allows rapid separation of each module from the frame of the corn harvester in order to eliminate possible problems (change of saw or the entire module assembly). The methods of the energy storage calculation and electric motor power selection for each module are presented

DEVELOPMENT AND RESEARCH OF A CORN HARVESTER WITH SWEEP FRAME DESIGN
DescriptionThe article demonstrates a possibility of creation of a corn harvester with a sweep frame mounted from individual modules. Such corn harvesters include modules for cutting stalks, snapping modules, conveyor modules for turning, stacking and feeding the stalks in the shredding unit, conveyor modules for supplying corncobs to the cleaning device placed on the sweep frame, leading and managing bridges, power unit, as well as conveyor belt for cobs and auger for discharging the crushed plant matter. The technique for calculating the grinding module drive was shown. The arrangement of the modules on the corn harvester sweep frame was demonstrated. Corn harvesting with the suggested module corn harvester allows not only reducing combine metal consumption and reducing corn ears injuring, but improving maintainability as well

DescriptionMulticriterial formulation for centers placement problem on many-weighted prefractal graph is proposed. Estimation of the radial criterion of prefractal graph generated by seed-star is shown. Polynomial algorithm centers placement on prefractal graph with preserving contiguity old edges is suggested. Estimation of computational complexity of the algorithm and the example of the work algorithm are considered

THE DEVELOPMENT OF THE THEORY OF THE INFORMATIONAL SOCIETY AND CYBERSPACE
DescriptionThe modern informational technologies and the Internet as a part of them are changing our world. These changes are the reason for genesis of new theoretical concepts in the middle of XX century, which research the influence of informational technologies on spheres of social life. Step by step we developed different theoretical concepts of “Informational society”, which try to predict the prospects of society. We have formed a new term of “cyberspace”, but scientists still argue about its meaning. One part thinks that it has only “network” meaning, which means that cyberspace is only the Internet, another part understands this term more widely, include the hardware part in this term. In this article, the author analyzes different theoretical concepts which research the question of genesis and development of informational society, and the process of forming of the term of “cyberspace”, research of the process of transformation of “postindustrial society” into “informational society”, highlight the main ideas of informational society concepts
