A NEW MATHEMATICAL MODEL FOR OPTIMIZING FRACTURE LENGTH IN THE IRANIAN OIL SAND RESERVOIR
DescriptionCreation of hydraulic fracturing in the physical structure of the reservoir rock is one important way to improve the productivity of oil and gas wells. These artificial channels increase ability of the reservoir rock for conducting hydrocarbons to the wellbore. In this study a new approach has been proposed for optimization of fracture half length in hydraulic fracturing operation. Also, this new method that is a combination of various fracturing geometry models has been proposed for modeling the hydraulic fracturing geometry. We have shown that there is a reasonable agreement between the result of pseudo 3D fracture geometry model and the predicted results from the proposed approach

QUANTITATIVE AND QUALITIVE ASSESSMENT OF SEEDS TRAUMATIZING WHILE USING MACHINES
DescriptionIncrease of gross grain collecting and minimization of cost of its production essentially depends on technologies and technical means, which are used while grain crops cultivation. At the same time the existing industrial seed farming and the grain’s production are assumed the multiple mechanical and thermomechanical impacts on grain from working tools of cars and units that leads to weevils’ traumatizing. Grain damage negatively affects its technological and fodder characteristics; seeds’ traumatizing causes the decrease in their sowing and fruitful features. It isn't possible to extract injured seeds from the pile because working tools damage the weevils itself and also there are small differences between damaged and undamaged weevils. It is possible to reduce grain traumatizing while machine preparation by reducing the quantity and extent of mechanical and thermomechanical impacts on weevils, by optimization of technological operations and by controlling the regimes and adjustments of working tools. The work of winnower machines M-819 KAS-10+SBVS-5 and AS- 10+ was researched while developing a technique of complex quantitative and quality standard of machines’ and tools’ influence on weevils’ traumatizing. It was ascertained that on different stages of weevils’ mechanical preparation it get different injuries in quantitative and qualitative expressions. It was offered to estimate the injuring ability of machines by the impact of seeds’ injures influence on its sowing features. Also there was a conception of traumatizing coefficient which includes either quantitative or qualitative debriefing influences of the traumatizing on grains features

Description
The level of competitiveness of the agricultural sector depends on the effective implementation of the import substitution policy and food security in the region in which all categories of the population at any one time must have physical and economic opportunities needed to get enough and safe food for an active, full and healthy life. In this context, the problem of increasing the competitiveness of regional agriculture in the new economic environment is relevant. Competitiveness characterizes the concentrated expression of the totality of possibilities of managing subjects of agriculture produce and to bring the products (goods, works, services) to the consumer. Solving the problem of increasing the competitiveness of regional agriculture is closely linked to an increase in the effectiveness of the quality management of products, increasing profitability of production, improving the system of state regulation of the agrarian sector of the economy. Principles of creation of an effective mechanism of state regulation and support the competitiveness of the agro-industrial complex include: agro-industrial protectionism; program-targeted regulation and maintenance of the guaranteed state support for agribusiness; efficient use of resources. The priority areas to ensure the competitiveness of regional agriculture are: to create conditions for the development of innovation and investment environment, the improvement of financial and economic state of the industry and agribusiness organizations, improvement of state support of the agrarian sector mechanisms

Description
Nowadays there is a deficit of irreplaceable and physiologically necessary nutrients in everyday ration to a large extent connected with unfavorable environmental conditions and the increase of morbidity of humans of all ages cause the cute necessity in the creation of functional food that is products with additional functions which are healthy nutritive and physiological characteristics. One of the main demands under their creation is in the positive influence of introduced products on the food value of products because they must be enriched with ingredients which have antioxidant properties. Therefore, nowadays the introduction of functional meat-plant products will promote the effective improvement in the direction of prophylaxis of different diseases. In Russia, the concept of healthy nutrition became a part of state politics. The aim of this politics is the conservation and consolidation of population’s health and the prophylaxis of diseases. In this work, there was considered the technology of the production of meat-plant tinned food of functional purpose enriched with nutrients and intended for preventive human nutrition, for those who are in the conditions of harmful influence of environment and professional activity. There were described the advantages of the given developing, there were recommended the introduced into the product components of functional purpose

IMAGES OF POT PLANTS IN ART, AS A RESOURCE OF INFORMATION ON THE AGRONOMY HISTORY
DescriptionThe article analyzes pot culture as a part of agronomy history. The basic emphasis focuses on plant species diversity, the collection of certain groups of plants and their role in the history of agronomy. The tool of analysis was the visual images of the plants in the paintings of artists of different periods. Earlier, we performed the work on the history of introduction the number of agriculture crops. This approach is a method of visual sketches or notes; it gives a capacious and complete view of the agronomy development, where the illustrations are the paintings. For the analysis, we have created the base of image on the basis on 170 paintings by artists of different periods.The approach used in the work, enables the development of observation, stimulates cognitive function in students and teaches to make comparisons and visual analysis. In the work, on the basis of visual analysis, we show that the spread of flowering plants was conducted very actively in Russia. "Exotic plants" have been firmly established in the Russian farmstead life and became its daily life. Love to plants has no clear social boundaries, everyone has this feeling. Modern approaches are noted in the breeding and preparation of new crops based on tissue culture , genetic engineering, which allow to receive new exotic pot plants, not demanding growing conditions

Description
The article is devoted to the development of a compressor type ozonator. It describes the design of a high-productivity compressor ozone generator, which can be used for industrial decontamination of mixed feeds, water, milk, and in the system of presowing treatment of seeds. This construction allows generating ozone with high concentration to 5 g/m3 at high feed air or oxygen from the compressor station (up to 2000 l/min). The article describes the design of the basic elements of tubular ozone generator, examines the factors influencing the productivity of the ozonator. The proposed mathematical model allows calculating the productivity of the ozonator when considering multiple influencing factors. These factors take into account: the parameters of supply voltage, such as the magnitude and frequency of the supply voltage; the configuration and geometrical parameters of electrodes such as, the area of the electrodes, the configuration of the surface of the electrodes and distance between electrodes; parameters dielectric barrier; and the transported gas parameters such as volume, temperature, pressure and composition. Special attention is paid to the design of the electrodes made of woven wire mesh with mesh sizes from 1.5×1.5 to 2.0×2.0 mm. It is noted, that such electrodes allow obtaining the maximum productivity of an ozonator, and they do not lead to overheating of the dielectric barrier, and do not output down the generator. In the same way, the article presents the results of the mathematical modeling of ozone generator productivity while changing various factors

DETERMINATION OF ACUTE TOXICITY OF BIO HUMATES
DescriptionIn the work, we present the results of the investigation of acute toxicity of bio humates obtained by the method vermicultivation on laboratory animals. In the diets of farm animals and Pets to fill in the missing nutrients in the past years, we had an extensive use of various feed additives. Among them, mineral (macro - and micronutrients), protein and fat supplements, vitamins, biostimulants, complex natural compounds (sapropel, peat), synthetic products (enzymes, hormones, antibiotics, adaptogens, antioxidants). The search for new ways of improvement and increase of efficiency of agricultural animals using feed additives with high demands on ecology of meat and dairy foods naturally led to increased studies on the use in livestock farming of water-soluble alkaline salts of natural humic acids - humates. Their environmental safety and the unique ability to improve metabolism and increase energy cells very positively manifested in living organisms. Numerous studies Russian and foreign scientists installed a high efficiency natural humates as biostimulators and immunomodulators in animal husbandry and veterinary medicine. Accumulated extensive experimental material, proving that the use of humates leads to faster growth of animals, reducing morbidity and mortality, increase the body's resistance to toxins in feed and resistance to adverse environmental conditions. Improving with the help of humates ecological purity of the ecosystems "water — soil — plant", as well as the health of birds, animals and fish will ultimately lead to strengthen health and to prolong human life as a consumer of agricultural products. Currently, the livestock market is intensively increasing the humates produced in Russia and abroad from brown coal, peat, sapropel. A special place among them has been occupied by the newest formulations because of a unique combination of safety, efficiency, and value, which, thanks to its amazing properties to increase energy cells, stimulate vital processes and to enhance the beneficial effects of other substances called energine. They are harmless to animals and humans; do not have allergologie, anaphylactogenic, teratogenic, embryotoxic and carcinogenic properties when used in recommended doses. This allows you to create on their basis organic natural feed additives and veterinary medicines for agricultural animals, birds, fish, fur animals and Pets, and preventive and therapeutic drugs for humans

Description
Expansion and increasing of the Krasnodar region transport infrastructure during the construction of the Olympic facilities together with the new land development created a necessity for construction in the remote areas of landslide slopes with the complex engineering-geological conditions. Constructions of bored piles, jammed by in nondisplaceable soil are often used as one of the measures for the protection of surface rocks landslide movement and tightening the slope weak sections. Such constructive solution is often being considered the best, and sometimes the only acceptable solution. When designing engineering protection it is recommended to consider the use of a number of active protection activities, aimed at the landslide processes stabilization. However, in case of construction production impossibility due to terms of organization, it is necessary to provide passive protection which would secure that the landslide streamlines the construction. Currently, the mechanism of the soil landslides interaction with constructions of detached objects spot protection isn’t studied enough. Known methods adopt simplifications and assumptions which lead to definite significant errors in the design of slope protection structures. Security and reliability of such structures can only be achieved with the adoption of high factor of safety values. This leads to increased material consumption and labor input for the erection of defensive structures also reduces the economic efficiency of these structures. In addition the process of designing protective structures in the Krasnodar region is further complicated by fact that the landslide of construction area is mainly folded by flowing clay soils
