Description
The level of development of modern medical equipment for the past 20-30 years is in constant development, many of the technologies and methods of treatment of certain diseases that were previously only available for the treatment of a person with success began to penetrate in the veterinary practice. The objective aim at the initial stage was the establishment of testing and suitability for the cultivation of autologous dermal fibroblasts animals of previously known techniques and the modernization of the existing techniques. Next, we had to carry out measurements of morphometric parameters and to identify structural features and functional activity of fibroblasts of different kinds of agricultural animals. Conclusions: The study showed the conducted morphometric autologous dermal fibroblasts tests allowed us to obtain the correlation line. In addition, to identify common patterns in the development and growth of fibroblasts derived from different species of agricultural animals. And also, to obtain material for comparative evaluation of the quality of the obtained cell cultures using entropy equivalent

A METHOD OF CALCULATING THE COMBINE PARK IN VARIOUS CONDITIONS OF CLEANING
DescriptionThe article discusses the technique of calculating the combine harvester under various harvesting conditions. The authors consider two options for optimizing the fleet of combines: the first, when the harvested area is set, the second, when the harvested area is not specified. In the first case, the harvester park is calculated for a known area with different harvesting times, but within the boundaries of the agro-industry. In the second variant, a park of harvesters is justified and it is calculated how much space it will be able to clean for a different duration of harvesting operations

Description
In this article, we show the necessity of formation of a new concept "the sustainable development of qualitatively new economy of the pre-business structures", which emphasize human capital, knowledge economy and scientific and technological progress with access to new technological way. The author substantiates the necessity of using a systematic approach to quantitative and qualitative evaluation of sustainability of small and medium enterprises. The article describes three types of economic goals of small and medium enterprises, the achievement of which is aimed at sustainable development. The main emphasis in the sustainable development of small and medium enterprises is done on a new quality of economic growth. We have developed a methodology for assessing the sustainability of development of small and medium business organizations. The proposed method of multicriteria evaluation of the pace and quality of economic growth of small and medium-go business to identify the priority criteria and determining the factor indicators. Summarizing the conducted researches allowed the author to establish that when combining the categories of sustainability, quality of growth and efficiency of business activities in a single integrated system it is necessary to consider the whole set of conditions and factors of the business environment to achieve set goals in the individual subsystems

RESEARCH METHODOLOGY OF THE SPRAY ALIGNMENT EFFECT ON QUALITY INDICATORS OF THE SPRAYER WORK
DescriptionThe article discusses the methodology of the study of influence of the angles of the spray nozzles on the quality indicators. The authors considered three options for placement of dispensers with preset angles. To determine the quality indicators we used a special technique based on the use of a personal computer equipped with a scanner with high resolution for entering information directly to the trapping surfaces

METHODS AND RESULTS OF THE SEED MATERIAL FRICTION COEFFICIENT DETERMINING USING AN AUTOMATED DEVICE
05.20.00 Processes and machines of agroengineering systems
DescriptionThe article describes the automated method of friction coefficient determination of row crops seeds using different types of surface, including modern polymer and composite materials. It is revealed that the friction coefficient characterizes the friction properties of seeds arising in the process of mechanical action during harvesting, transportation, storage and processing, as well as changes over time depending on the state of the surfaces, contact time, humidity, relative velocity and other parameters. The problem of lack of friction coefficients values for rest and dynamic friction coefficients for the polymeric and composite materials which are actively applied today at industrial production of agricultural machinery is designated. The design and general view of the device which helps to determine friction coefficient excluding the human factor (operator error) are presented. The operation principle of the developed device is described and the processing method of experimental data is given. Experimental data were obtained and statistical processing was carried out to identify the static and dynamic friction coefficients of seeds. Integral ( ) and differential ( ) graph for the distribution of friction coefficient average values for pairs "type of seed material – type of friction surface" are constructed
