The article presents analysis of the problem of increasing the quality of the implementation of mechanized operations to harvest crops and seed dressing chemicals. The quality of grain harvesting combine harvesters was considered for the new modern harvesters in terms of crop losses, grain crushing and microdamages. The quality of seed treatment is considered on the basis of the ejection slot-spraying nozzles at ultra low seed coming down with a conical distribution surface, ending rounded shape logisticians. The problem of improving the quality of the grain harvest is mainly due to its losses for the combine and injury. By the way, the amount of grain crushing almost half its losses determines the percentage of the combine. The greatest fragmentation occurs in the threshing and separating device (LSG) combines with a hammer drums and several times lower - in the axial rotor LSG. At last there is a big advantage - high performance combines that preference when replacing obsolete machines with a hammer apparatus. Quality depends on the etching uniformity of distribution of atomized liquid droplets and completeness of etching. The proposed new flowsheet Dressers fixed flow distribution and ejection-slotted spray solution of the working fluid has significant advantages: reliable processing of seeds, completeness (not less than 97%) and uniformity (98%) of dressing material. Optimal duty cycle flow of seeds created by a fixed cone with an angle of 45 degrees, the spatial arrangement of ejection nozzles relative to the flow of processed seeds provide good quality of work
The impact of pectins and its concentration on probiotic characteristics of the beverages has been studied for developing the formulation and technology of pectin beverages. Samples of sour-milk products with dry pectin (Unipectin OB 700) and liquid one (pectin apple extract is produced by SunLand) was made. Sour milk microorganisms and bifidobacteria content were defined. High sour milk microorganisms and bifidobacteria content as well as high rate in souring were revealed in the preparatory samples. However, liquid pectin is easier in use. Consequently, the formulation of pectin extract beverages was developed and optimized by using Mathematical Modeling. The samples of beverages were produced and their quality characteristics were evaluated. An optimal fruit/vegetable fillers / whey ration was defined to get the product which combined balanced micronutrient composition, its functional activities and gustatory qualities. For that a three-factor simplex-centroid design was used. The samples produced according to the design matrix were tasted and evaluated by color, flavor, aroma and consistency according to the ten score points scale. The findings were processed with statistical and graphical analysis. The last one used the construction of ternary graphs with the help of «Statistica 7,0» program that allowed to define the most acceptable ranges of fruit/vegetable fillers / whey components in the beverages: fruit juice – 4-16%; pumpkin juice-4-16%; whey -4%. Chemical composition, organoleptical indicators and physicochemical parameters of ready-to drink beverages were examined. As a result, these beverages have been recommended for school feeding as the source of dietary fiber, minerals and vitamins
The author of the article compares native and foreign approaches to teachers’ of health and safety training and specifically to their realization in the republic of Poland. Acquired experience and data are applied by the author of the investigation for teaching the health and safety discipline; they are explored and used in realization of teaching courses of health and safety. The prime object of the discipline is to provide students with information in the aspect of safety and to form the conduct in real extreme conditions, being in habit of preventing risks, to equip them with information about risks of modern life. Students also must be able to feel confident in quite a deep field, that is: framework of civil protection, rules of behavior in case of risk, first-aid treatment in case of emergency, protection from various threats, debridement and sanitary, warning others of danger. In graduate classes of secondary school we observe understanding of the structure of national defense, compliance with obligations in the area of defense by authorities and citizens, threats in peacetime and in the war-time. Essential principles of an elective course in health and safety for graduate classes in schools and gymnasiums are peace maintaining, cooperation and unification of countries as a guaranty of safety, factors of ecological risks, International Humanitarian Law. Having conducted a detailed analysis of curriculums in health and safety in Poland, the author draws a conclusion that it is largely alike the realized Russian one
Modern society development makes higher demands to personality education and development. Formation of the comprehensive and harmoniously developed personality acts not only as the objective requirement, but also becomes the main goal (ideal) of modern education. Nowadays graduate of comprehensive school, lyceum, gymnasium or military school is the potential patriot, professional, and leader. The researches made allowed to state: formation of senior cadets leadership qualities is impossible without teachers assistance, and comprehensively thought over and purposeful program. The formation program of senior cadets’ leadership qualities is reasonably considered in this article as well as its pedagogical
methods realization. Individual approach application features are discussed as one of the main principles of pedagogy in education of future leaders
In the article we consider some main tendencies which are characteristic for development of modern natural sciences and for ontology and the theory of knowledge’s process. Features of synergetic as interdisciplinary scientific direction, the concept of a universal evolutionism, value of information in nature development are discussed. Methodological basis of the process of integration of scientific knowledge is the interdisciplinary direction of the research which important component is the synergetic. It plays an important role in the concept of coevolution realization which considers mutual relation of the person and the nature, the micro- and the mega-world. The article demonstrates that having revealed the laws of functioning of complexly evolutionizing, nonlinear systems, synergetic thus posed the fundamental questions of both epistemological and ideological and value nature. Conceptual shifts occurring in cognition open up the new sides in the interpretation of not just order and disorder but also the categories they generate. The author points out on the features of synergy, which using the linearity аnd nonlinearity in the theory expresses the aspects of material unity of the world, linked to the general properties of self-development of complex systems. The universe is seen as a dissipative system with periodically removable elements (elementary dissipative systems)
The problem of transition from the abstract and general dialectics to the concrete and common theory of development, the problem of diachronic of dialectic and synergetic cognition’s culture in the context of comporation between the philosophic and natural science are discussed in the article. The hypothese of cosmologic singularity the birth of tte world from «nothing» and the role of «dark materia» in the developing’s process of our Universe are also described. The author points out on the features of synergy, which using the linearity аnd nonlinearity in the theory expresses the aspects of material unity of the world, linked to the general properties of self-development of complex systems. The universe is seen as a dissipative system with periodically removable elements (elementary dissipative systems). The spontaneous disbalance of symmetry and the appearance of new physical forms of existence are characteristic for the elementary parts. The order? The symmetry and the spontaneous disorder in the symmetry are the phenomena of self-organization of the material. The scientific results which we found with the quantum theory of field, can give us the theoretical descriotions of such forms of existence that’s why the structural unity in all levels of materia can be explained in the quantum and field image of the world
The article discusses the concept of "institutional infrastructure" and clarifies its essential content in relation to market cars. In terms of the industry market the main purpose of the institutional infrastructure is achieving the maximum economic benefit within limited resources. The main tasks that need to be solved in order to achieve this goal were formulated. We have developed and proved structurally-logical chart of the elements of the institutional infrastructure. The content of the institutional infrastructure of the car are presented and justified. The analysis condition of the car market’s institutional infrastructure showed the problems associated with the state of institutions which have an impact on the functioning of the car market. Measures to stimulate the car market does not cover entire sector as a whole, and imported institutions do not give the expected effect because of inconsistency formal and informal elements of the institutional infrastructure. Presented assessment of the institutional infrastructure of the car market confirms the dependence of the state of the industry market cars from institutional infrastructure. Only reforming the institutions at all levels of the industry, from production to car sales can have a positive effect on the industry. Changes in the institutional infrastructure should be focused on improving the competitiveness, stability and independence from external factors
The article considers the issues of actualization of the problems of formation of professional competence in the process of studying the course of "Mat-mathematics" on the example of economic specialties. Noting the fact that economic specialty is the specialty that integrates information from the mathematical, natural, gum humanitarian and socio-economic subjects, and the approach to the selection of the content of the mathematics course must be focused on the mate-automatic machine for all cycles, forms of relevant abilities and skills. Therefore, the importance of the problem of developing these tasks and exercises that would help to create such skills for effective application of the theoretical material and the development of research skills. In this article we have discussed some of the design techniques and examples of using the so-called mo-practical problems. The efficiency of the use of model problems in the study of mathematics teaching clarifies the fact that most knowledge activity of students achieved in the research of the issues directly related to their willing profession. They are developed in accordance with the program of the mathematics course and cover all of its major sections. Model-specific tasks may be offered to students in the form of the model calculations, the execution of which should last for a long time, in the form of records insistent or control work directly in the classroom, in the form of term papers, etc. This article also contains the justification of the need of development of didactic materials, designed to optimize student learning professional mathematical competencies
The effectiveness of disinfection depends on used disinfecting materials for vans, their actions and technological parameters of the installation for applying disinfectants. Hot mist generators provide uniform distribution of particles of disinfectant solution inside the van for transportation of agricultural products. The parameters of the generator of hot mist affecting the quality of disinfection were investigated. Tests were conducted for the vans used to transport agricultural products. For studies we used the vans in operation, which transport farm animals (pigs) and had been disinfected before. Sampling for the research on contamination was performed with pre-prepared swabs. Factorial experiment was planned with using scheme #32, and as a result of significant factors in the univariate experiments we set a temperature of the aerosol disinfectant solution and the duration of surface treatment. As an optimization function we have chosen disinfection efficiency of bodies of vehicles carrying agricultural products. Comparing the results of the experiments on different groups of microorganisms we have found that the optimal mode of hot mist generator with a dispersing device are: the processing time of 1 m2 - 8.5 at the processing temperature - 65º C
Potatoes in our country are one of the most cultivated cultures in agriculture. The most time-consuming process in the production of potatoes is harvesting. Currently for potato harvesting potato harvesters or diggers are used. Existing machines are not sufficiently well-behaved in adverse operating conditions such as the high and low humidity. Quality of work of the units and devices of potato harvesters depends on the digging working parts. In the process of potato harvesting up to 1000 tons of heaps from 1 hectare go through the units of the machine, which includes plant residues and dense soil out of row spacing. To eliminate or reduce the impact of this lack, on either side of the coulter we set cutting discs which prevent ingress of heaps out of row spacing. However, due to the imperfections of the design they are slipping during operation what causes accumulation and enhancing traction resistance. Based on these facts, the work on improving the digging working parts in the actual and future challenges for the country's agriculture
