Relevance. The most important influence on the yield, the timing of growing vegetables in greenhouses and the cost of the resulting crop, in addition to the arrival of solar radiation, is exerted by the presence of a system of artificial lighting in greenhouses and its capacity.It is no exaggeration to say that today artificial lighting in greenhouses is more effective than natural lighting. So, to obtain one kilogram of vegetables using artificial lighting, it is necessary to spend 4.5-5.0 thousand J/cm2, and in the case of natural lighting: 5.0-6.5 thousand J/cm2. This is due to the fact that when using artificial lighting in the greenhouse, we create the most comfortable growing conditions for the plants. Of course, every culture, every hybrid requires its own illumination parameters, so you should not try to formulate what the ideal artificial lighting will be. Proper lighting means getting the maximum yield from your crops at the lowest cost. An increase in the productivity of plants when grown under photoculture conditions occurs not only due to an increase in the lighting power per unit area of greenhouses, but also due to correctly selected hybrids. The cultivated hybrid is one of the most important criteria for both increasing its productivity and improving the quality of the fruit. But not all tomato hybrids recommended by breeding companies for growing under artificial lighting are ideal for such conditions.Methods. The methods used in agronomic science were used. The information base of the research was made up of reference materials from specialized publications on the subject under study (catalogs of breeding companies); materials received from participants in the greenhouse vegetable market (breeding companies, greenhouse plants); own research, articles and reviews in specialized journals.Results. Correctly selected tomato hybrids provide a significant increase in productivity in greenhouses, an improvement in fruit quality and a balanced cultivation technology under these conditions. An assortment of recommended tomato hybrids for growing in photoculture conditions is presented, an analysis of their advantages and disadvantages is made, and the main requirements for hybrids for these conditions are formulated.

The article analyzes the world experience in methods of applying of stomach nutritional fistula. Different methods of gastrostomy are described, their classification is given. The advantages and disadvantages of common surgeries are outlined. The most often used traditional surgeries are: gastrostomy by Stamm, Topver and tubular gastrostomy. Complication rate of these operations led to a further search for minimally invasive techniques: percutaneous puncture, laparoscopic gastrostomy, and laparoscopically- assisted percutaneous endoscopic gastrostomy. A significant disadvantage of minimally invasive puncture techniques is the need to purchase relatively expensive disposable sets for primary installation and replaceable low profile tubes. The cost of these supplies in Russia is much higher than the money allocated in the obligate medical insurance system, which makes the method economically unprofitable for medical institutions and patients. Partially, the costs could be reduced by the use, as a gastrostomy tube, a Foley urinary catheter. There are several studies that have confirmed economic advantages and absence of a reliable difference in the number of complications and duration of use such tubes. However, some complications are reported: migration of catheter into the duodenum with the development of obstruction, decreased comfort and quality of life. The conducted study showed absence of classification of gastrostomy types and their complications. The final consensus in clinical use of different types of gastrostomy in different situations is absent. There is a tendency to decrease rate of traditional laparotomical operations in favor of less invasive interventions making it difficult for adequate analyzing. In cases with need for revision, biopsy and fundoplication, laparoscopic or laparoscopically-assisted percutaneous endoscopic gastrostomies are preferred which has proven itself in children. For a group of palliative patients of elderly age with high risk and doubtful prognosis, minimally invasive puncture gastrostomes are more appropriate.

Исследовано влияние подготовки зернового сырья на качество получаемого комбикорма. Объектом исследования было зерно пшеницы фуражной, кукурузы, сои, ячменя. Для получения комбикорма зерно измельчали на плющильном станке Neuero (Германия), на котором в зависимости от технологических свойств перерабатываемого зерна можно измельчать его или получать плющеные продукты. Установлено, что при измельчении зерна пшеницы фуражной, кукурузы, сои, ячменя влажностью до 12 полученные частицы зерна разных культур значительно различаются по величине и образуется до 25 мелкодисперсной фракции, что ухудшает в дальнейшем процесс смешивания, а также увеличивает потери продукта. При плющении зерна пшеницы фуражной, кукурузы, сои, ячменя после его увлажнения до 13,513,9 и отволаживания в течение двух часов количество мелкодисперсной фракции в полученном продукте уменьшается в 34 раза, частицы плющеного зерна разных культур незначительно отличаются по величине, а показатель модуля крупности увеличивается в 1,33 раза в зависимости от культуры, поэтому полученные плющеные продукты из зерна разных культур легко смешиваются. Производство комбикорма с использованием плющильного станка Neuero по предложенной схеме подготовки зернового сырья на животноводческих предприятиях и в личных подсобных хозяйствах экономически выгодно, поскольку сократит транспортные и энергетические расходы, что, в свою очередь, существенно снизит себестоимость животноводческой продукции. Influence of preparation of grain raw materials on quality of the obtained compound feed is investigated. Grain of fodder wheat, corn, soybeans, barley was the object of research. To obtain feed grain was processed on the flattening machine Neuro (Germany), which, depending on the technological properties of the processed grain can grind it or obtain flattened products. It was found that when grinding grain of feed wheat, corn, soybeans, barley with humidity up to 12, the obtained grain particles of different cultures differ significantly in size and up to 25 of the fine product is formed, which further worsens the mixing process, and also increases product losses. With the flattening of wheat forage, corn, soybeans, barley after the moisture up to 13,513,9 and binning within two hours the amount of fine fraction in the resulting product is reduced in 34 times, particles flattened grain different cultures differ slightly in size, and an indicator module size increases are 1,33 times, depending on the culture, so the resulting flattened products of grain of different cultures are mixed easily. The production of compound feed using flattening machine Neuro on the proposed scheme of preparation of grain raw materials for livestock enterprises and household farms cost-effective, as it will reduce transport and energy costs, which in turn will significantly reduce the cost of livestock production.

Entomopathogenic nematodes (in the genus Steinernema and Heterorhabditis) have been studied and successfully commercialized as biological control agents. These organisms are highly virulent and safe for the non-target environment, animals and humans. For at least 200 target species, the nematode-bacteria complex has the potential to become a mass-marketed agricultural biopesticide. However, before nematodes can be successfully integrated into the agricultural system as a regular-use, “go-to” biopesticide, it is necessary to develop economical manufacturing processes. There are several manufacturing platforms: in vitro solid fermentation; in vitro liquid fermentation; and in vivo production. This review presents an analysis of each approach and discusses the advantages and disadvantages relative to the cost of production, technical expertise required, and quality of the final product.

The paper proves the relevance of the importance and determining role of the internal control system in the design and modeling of transport and warehousing processes. The peculiarities of warehousing and transportation of the researched material are investigated and systematized. A number of methods for controlling the quantity and quality of the studied material are described, and their advantages and disadvantages are described. One of the main factors that must be taken into account when developing a design model of the transport and warehousing process is the ability of this process to conduct quality control procedures for its implementation. That is, if the process cannot be controlled, it cannot be controlled. It is necessary to take into account the cost of control procedures, in relation to the project itself. It is possible that the cost of control will exceed the cost of the project itself, which with all the forecast indicators of profitability and investment attractiveness may make its implementation impractical. The purpose of the paper is to study the control aspect of transport and warehouse modeling. The analysis of the scientific literature indicates the need for additional development of methodological and organizational support for internal control systems in the modulation of transport and warehousing processes. The study of this issue allowed to reveal a number of features of warehousing and transportation of certain groups of material values, on the example of the studied material – cement. There are also a number of typical methods for controlling the quantity and quality of cement in the warehouse. This approach allows us to identify the features of the control environment of this material, which must be taken into account in the transport – warehouse modeling.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

Cloud computing has been envisioned as the definite and concerning solution to the rising storage costs of IT Enterprises. There are many cloud computing initiatives from IT giants such as Google, Amazon, Microsoft, IBM. Integrity monitoring is essential in cloud storage for the same reasons that data integrity is critical for any data centre. Data integrity is defined as the accuracy and consistency of stored data, in absence of any alteration to the data between two updates of a file or record.  In order to ensure the integrity and availability of data in Cloud and enforce the quality of cloud storage service, efficient methods that enable on-demand data correctness verification on behalf of cloud users have to be designed. To overcome data integrity problem, many techniques are proposed under different systems and security models. This paper will focus on some of the integrity proving techniques in detail along with their advantages and disadvantages.
