The fishery complex is an integral part of the national economy. Fish and its processed products are an important part of a balanced and healthy diet. They do not have an alternative replacement, therefore, an efficiently functioning fishery complex plays a big role in ensuring the country's food security and preserves aquatic biological resources. In coastal areas, it is a center of labor force employment, since fishing cannot do without related industries: shipbuilding, production of gear, processing, packaging and transportation of fish products, and therefore it is the core of production and port infrastructure, an incentive for the development of the social sphere and a center attraction of innovation. Currently, the industry is experiencing difficulties associated with both internal and external problems. For further progressive development of the complex, it is necessary to attract investors and financing from various sources for the technical re-equipment of the existing material and technical base, as well as create completely new production assets. A potential investor needs information about the possible pluses and minuses, acquisitions and losses. Therefore, the purpose of this study is to analyze the potential investment attractiveness of the domestic fisheries complex. In theoretical science there is no definition of investment attractiveness. Therefore, when conducting this study, the authors followed the canons of classical economic theory and used comparison methods, historical, deduction and induction, statistical and others. Analyzing the legislation, regulatory documents, scientific articles, monographs, reviews, they came to the following conclusions: the fishery complex has an investment attractiveness under a set of certain conditions. The potential for investment attractiveness of the fishery complex at the present stage is characterized by the presence of a legislative base, increasing demand for fish in world markets and domestically, the stability of the conditions for obtaining quotas for fishing and aquatic biological resources, government participation in co-financing projects, the availability of a state order for finished products, and scientific opportunities capacity etc.

The Stability

In the context of the modern global financial world order, an important element of the stability of the national monetary unit of the overwhelming majority of countries in the world, especially developing countries, is foreign exchange earnings. For some countries with favorable natural and climatic conditions, the production, processing and export of agricultural products plays a significant role in the overall structure of foreign exchange earnings in the country. The constantly increasing demand from consumers for fruits, berries, nuts and their processed products allows economic entities of national fruit and berry subcomplexes to increase the volume of growing and exporting these types of products. This study analyzes the change in the volume of exports and imports of fruit and berry products in value terms for the period 2010-2019. It is revealed that some states, being the largest exporters of fruits, berries, nuts and products of their processing, occupy significant positions in the import of these types of products from abroad. Based on the author’s calculations, the top 30 countries of the world have been compiled in terms of net foreign exchange earnings from international trade in this type of product. According to this indicator, the first line with a level of $ 7.506 billion was occupied by Spain, while it increased it by $ 1.675 billion over 10 years. As for Russia, despite the counter-sanctions against the countries of the European Union and some other countries of the world, as well as the ongoing policy of import substitution, including in domestic gardening, it continues to be one of the main importers of fruits, berries, nuts and their processing products in the world. Thus, our country supports both foreign producers and other commercial structures that carry out the processes of commodity circulation of fruit and berry products, and the receipt of foreign exchange earnings in these powers.

Thomas More is often called a “humanist,” and rightly so if the word has its usual meaning in scholarship on the Renaissance. “Humanist” has by now acquired so many different and contradictory meanings, however, that it needs to be applied carefully to the likes of More. Many postmodernists tend to use the word, pejoratively, to mean someone who believes in an autonomous self, the stability of words, reason, and the possibility of determinable meanings. Without quite arguing that More was a postmodernist avant la lettre, this essay suggests that he was not a “humanist” who stalks the pages of much recent postmodernist theory and that in fact even while remaining a devout Catholic and sensible lawyer he was quite as aware as any recent critic of the slipperiness of human selves and human language. It is time that literary critics tightened up their definition of “humanist,” especially when writing about the Renaissance.

AbstractObjectivesThe stability of the analytes most commonly used in routine clinical practice has been the subject of intensive research, with varying and even conflicting results. Such is the case of alanine aminotransferase (ALT). The purpose of this study was to determine the stability of serum ALT according to different variables.MethodsA multicentric study was conducted in eight laboratories using serum samples with known initial catalytic concentrations of ALT within four different ranges, namely: <50 U/L (<0.83 μkat/L), 50–200 U/L (0.83–3.33 μkat/L), 200–400 U/L (3.33–6.67 μkat/L) and >400 U/L (>6.67 μkat/L). Samples were stored for seven days at two different temperatures using four experimental models and four laboratory analytical platforms. The respective stability equations were calculated by linear regression. A multivariate model was used to assess the influence of different variables.ResultsCatalytic concentrations of ALT decreased gradually over time. Temperature (−4%/day at room temperature vs. −1%/day under refrigeration) and the analytical platform had a significant impact, with Architect (Abbott) showing the greatest instability. Initial catalytic concentrations of ALT only had a slight impact on stability, whereas the experimental model had no impact at all.ConclusionsThe constant decrease in serum ALT is reduced when refrigerated. Scarcely studied variables were found to have a significant impact on ALT stability. This observation, added to a considerable inter-individual variability, makes larger studies necessary for the definition of stability equations.

It has recently been shown that the interpretation by partial differential equations (PDEs) of a class of convolutional neural networks (CNNs) supports definition of architectures such as parabolic and hyperbolic networks. These networks have provable properties regarding the stability against the perturbations of the input features. Aiming for robustness, we tackle the problem of detecting changes in chest X-ray images that may be suggestive of COVID-19 with parabolic and hyperbolic CNNs and with domain-specific transfer learning. To this end, we compile public data on patients diagnosed with COVID-19, pneumonia, and tuberculosis, along with normal chest X-ray images. The negative impact of the small number of COVID-19 images is reduced by applying transfer learning in several ways. For the parabolic and hyperbolic networks, we pretrain the networks on normal and pneumonia images and further use the obtained weights as the initializers for the networks to discriminate between COVID-19, pneumonia, tuberculosis, and normal aspects. For DenseNets, we apply transfer learning twice. First, the ImageNet pretrained weights are used to train on the CheXpert dataset, which includes 14 common radiological observations (e.g., lung opacity, cardiomegaly, fracture, support devices). Then, the weights are used to initialize the network which detects COVID-19 and the three other classes. The resulting networks are compared in terms of how well they adapt to the small number of COVID-19 images. According to our quantitative and qualitative analysis, the resulting networks are more reliable compared to those obtained by direct training on the targeted dataset.

The computation of angular acceleration of a rigid body from measured linear accelerations is a simple procedure, based on well-known kinematic principles. It can be shown that, in theory, a minimum of six linear accelerometers are required for a complete definition of the kinematics of a rigid body. However, recent attempts in impact biomechanics to determine general three-dimensional motion of body segments were unsuccessful when only six accelerometers were used. This paper demonstrates the cause for this inconsistency between theory and practice and specifies the conditions under which the method fails. In addition, an alternate method based on a special nine-accelerometer configuration is proposed. The stability and superiority of this approach are shown by the use of hypothetical as well as experimental data.

Abstract If, in a vertical, downward miscible displacement, the transition zone between the displacing and displaced fluids is neglected, a criterion for stable displacement can be obtained by considering a small hypothetical protrusion of one of the fluids into the other. This criterion leads to the definition of the well-known critical rate, uc = kg ??/?µ. The consideration is further extended by taking into account the transition zone that develops as a result of diffusion and mixing. A generalization of the previous criterion leads to the definition of another characteristic rate, the stable rate, which in actual miscible drives will be less than the critical rate. In such drives, the entire transition zone is stable at rates less than the stable rate. At rates between the stable and critical rates, the displacement is only partly stable, i.e. part of the transition zone adjacent to the displaced fluid is in an unstable position. From that part of the transition zone viscous fingers will develop. At rates greater than the critical rate the entire displacement is unstable and viscous fingers will develop more strongly. Results of laboratory experiments are in agreement with the expected behavior based on the theoretically deduced stability of the displacement. INTRODUCTION The simplest form of miscible drive in an oil-bearing formation is the injection of a fluid that is completely miscible* with the oil under reservoir conditions. In general, such a fluid, a solvent for example, is less dense and less viscous than the oil present in the formation. If it is injected into a horizontal homogeneous layer, gravitational forces will lead to the formation of a gravity tongue of solvent in the upper part of the layer and the adverse solvent-oil viscosity ratio will cause viscous fingers to develop. If, however, the solvent is injected up-structure into a dipping layer, gravity has a favorable effect, because it tends to keep the less dense solvent up-structure. Tongue formation and viscous fingering are consequently reduced and it is even possible that they will be suppressed completely. Viscous fingering and gravity tonguing are the consequences of the instability of the displacement. A stable displacement cannot result in growing viscous fingers and/or growing gravity tongues. Since large amounts of oil can be bypassed if there is viscous fingering and/or gravity tonguing, the stability of a miscible drive is very important with respect to the recovery efficiency of the drive. The stability is of particular importance in miscible-slug drives, as it determines how quickly the miscible slug between the displaced and displacing fluids will be distorted and broken up, after which the drive is no longer completely miscible. Stability is thus a most important factor in determining the success of a miscible drive, and it is considered that the aspects of stability considered in this paper will make a useful contribution to existing theories. Consideration is given only to vertical downward displacements, in which no gravity tongues can develop and which are therefore simpler than downward displacements in sloping layers.

In a market economy, it becomes important to improve the organization of enterprise management and, above all, the production process, efficient use of financial, material resources and inventories. Effective management of material resources increases profits and provides the necessary investment. To maintain high profitability and liquidity, the management of current activities of enterprises, in particular inventory management plays a significant role. The categorical apparatus of material resources management at the enterprise is considered, the definition of “material resources” is generalized, the definition of "material resources management" is offered, and also the system of material resources management at the enterprise is considered. In the management of material resources at the enterprise there are 2 approaches – logistics and reengineering. The main tasks of the mechanism of management of material resources of the enterprise of building materials are defined. These are: increasing the efficiency of material resources and choosing cheap sources of funding; introduction of new production, resource-saving technologies; minimization of costs for procurement, production and marketing activities; increasing the interest of employees of all services in the effective performance of their duties; product quality management. The analysis of efficiency of use of material resources at the enterprises of building materials which has shown, that manufacture of production is rather material-intensive is carried out. This is evidenced by the share of material costs in the cost of work, and the value of the utilization factor of materials indicates the economical use of material resources in production. Reserves for improving the efficiency of material resources at construction materials enterprises have been identified. The ways of the most rational use of material resources of construction materials enterprises are offered, in particular it is improvement of a design and technology of manufacturing of products, introduction of more progressive norms of expenses of resources, use of substitute materials, and reduction of losses at stages of transportation, storage and industrial use.

The steadily increasing demand for semi-finished meat products is provided by the constantly expanding product range and improving its quality. In turn, quality stability is an important criterion for increasing sales. The article presents data on the effect of a natural antioxidant-dihydroquercetin on the stability of consumer properties of chopped semi-finished moose meat with the addition of beet fiber when stored at a negative temperature for 216 days. Dihydroquercetin was added in an amount of 0.05% by weight of the raw material. In the course of the work, generally accepted methods of studying organoleptic and microbiological quality indicators were used. The degree of oxidative deterioration of the product was checked by determining the acid, peroxide and thiobarbituric numbers. The conducted studies allowed us to conclude that the use of this food additive allows us to preserve the organoleptic and microbiological properties of the semi-finished product for a longer period by inhibiting the formation of oxidation products. The use of dihydroquercetin contributed to a decrease in the experimental sample of the semi-finished product on day 216 of the peroxide and acid number by 2 times, and the thiobarbituric number by 1.8 times in relation to the control. Thus, by reducing the oxidative damage of the semi-finished product, it is possible to influence its characteristics during storage.

 The article discusses the distribution of financial resources with a preference   for land assets and production of deep processed products with the highest added value, which simultaneously increases the incomes of producers and improves government revenues by increasing tax receipts. It is noted that the progressive development of agriculture depends on the technical modernization of the industry, which also requires investment. Therefore, it is necessary to subsidize the modernization and reconstruction of fixed assets - granaries, greenhouses. Potential profit, which will become an important component of investment, can give a boost to the investment activity. An analysis was carried out on the conceptual foundations of building economic relations in modern agricultural production. The conditions for the agricultural development have been assessed, and critical insights on mechanisms for implementing state and regional target programs have been provided. In terms of a systemic approach to the State economic management, the economic processes should be considered as a system of financial relations that interacts with other systems. In this regard, the paper presents a model that reflects the conceptual framework for managing financial flows. This model provides an overview of managing economic processes, and may take into account many elements and factors.
