Feline mammary hyperplasia is a non-neoplastic condition, characterized by daily hypertrophy and hyperplasia or proliferation of the stroma and ductal epithelium of the mammary glands and usually affects young uncastrated cats. The most affected cats manifest enlarged, swollen, ulcerated breasts, in addition to other nonspecific signs. The diagnosis can be given through the history and clinical examination, but confirmed only with histopathological examination of the lesion. This study reports the case of an uncastrated cat, only 3 months old. It was attended with complaints of an increase in volume in the abdominal region about 3 weeks ago, with rapid growth 7 days ago. In this case, the clinical and historical aspect of the still very young patient, without having manifested his first estrus, were atypical. Thus, in addition to the fact that the imaging test was suspected, it was first suggested to be another pathology, which was discarded at the surgical moment, where the mass was removed by partial mastectomy, being confirmed the diagnosis of feline mammary hyperplasia at histopathological examination.

Purpose: to identify the relationship of sorption of a complex sorbent with a temperature factor and its mathematical substantiation. Material and methods. As a material for the study, a complex sorbent obtained from a mixture of perlite and agroionite in a ratio of 27:73 was used. The experiment was carried out in laboratory conditions at different temperatures. At certain intervals, when measuring the total salinity of the solutions, the temperature parameter was also measured. During the study, the air temperature was measured. For the experiment, a model water of three salinity levels: 3.1; 5; 7 g/l was used. The weighed portions of a mixture of sorbents weighing 27.5 g with model solutions, 300 ml each, were placed in a reservoir. Measurements were carried out after 5; 10; 20; 30 min; 1; 2; 24; 48 h using a HI 8733 conductometer from Hanna. Results. As a result of the study, the dynamics of the salinity of the model water under the action of a complex sorbent was obtained, a scatter diagram was constructed. It is a statistical analysis tool, with the help of which the dependence and the nature of the relationship between the two process parameters are revealed. According to the results obtained, it can be concluded that there is a positive relationship in the experiments performed. The efficiency of the process depends on temperature readings with a slight deviation. Thus, at an average temperature of 26.3 °C, the total mineralization index is lower than at an average temperature of 19.8 °C. Conclusions. By constructing a scatter diagram and a matrix scatter diagram, a nonlinear relationship between sorption by a complex sorbent and the temperature factor was revealed.

Published: December 2020

Purpose: analysis of the impact of industrial waste storage facilities on surface and underground water supply sources. Materials and methods: according to the data of Federal Service for Supervision of Natural Resources, an annual significant increase in the volume of generated and stored waste was determined. One of the global problems associated with the impact of waste ponds on the environment is the contaminated filtrate formed in its body. As a rule, the absence of proper waterproofing at the basis of storage ponds of various purposes leads to contamination of ground and surface water supply sources, soil and adjacent territories. Previous measures aimed at the construction of a “clay castle” with a thickness of 0.5 to 1.0 m are insufficiently effective, and the polymer films used in the base of the storage ponds were characterized by rapid damage and low durability. Results: the analysis and review of the studies carried out by various authors showed that to reduce the pollution of surface and ground waters with harmful substances during the waste ponds operation, a set of measures to prevent the penetration of polluting components into water bodies should be taken. Conclusions: to prevent contamination of surface and groundwater sources at the base of the reservoir, it is necessary to use impervious and drainage facilities, which allow to eliminate the flow of contaminated leachate into the soil and underlying beds in advance. The impervious screen and a drainage system facility of modern geosynthetic materials (for example, three-layer drainage mats combined with impervious geomembranes and geotextiles) will not only effectively remove contaminated filtrate from the waste ponds, but also reduce the flow of pollutants into the aquifers.
ON ISSUE OF CALCULATION AND USE OF PARSHALL FLOW-METERING FLUME WITH MODERN WATER METERING DEVICES
Authors:   Russian Scientific Research Institute of Land Improvement Problems, Yuchenko L. V. , Vasilchenko A. P. ,   Russian Scientific Research Institute of Land Improvement Problems
Published: December 2020

Purpose: the use of a flow-metering flume and a modern metering device for water metering in an open canal with a flow rate of up to 1.5 cubic meters per second with the subsequent prospect of automating the measurement process. Materials and methods: the main function of the hydrometric structure – giving the fluid flow a given regime and pattern within a limited channel is theoretically used in the article. With the help of a hydrometric structure (Parshall flume) using the well-known “velocity-area” method, it is possible to determine the functional dependence of the water flow rate on one measured parameter, in this case on the level. With the use of modern sensors or devices for metering this parameter, it is easy in the future to automate the process of its metering, registration and transmission over a distance. Results and Discussion: the calculation of the maximum flow rate of the chute according to the selected empirical formula showed the correct selection and calculation of its parameters for the structure in accordance with a given maximum flow rate (up to 1.5 cubic meters per second), which does not require additional calibration of the chute during application. Conclusions: recently, more and more attention has been paid to the accuracy of used water metering in open irrigation canals with a low flow rate. With introduction of new modern devices that convert the measured parameter into the amount of measured water flow, the relevance of their use together with hydrometric devices increases. To measure water flow in an open canal, it is proposed to use Parshall flume with a modern measuring device, consisting of a submersible pressure sensor and a remote control and monitoring unit installed in a stilling well. The description of design and an example of clarifying the geometric dimensions of a flume with a measured water flow rate of up to 1.5 cubic meters per second is provided. The design diagrams of the flume and stilling well with the placement of a modern measuring device are presented.

Purpose: analysis of existing ultrasonic methods and devices for metering water flow in irrigation and drainage systems. The problem of rational use of water resources exists in all areas, including agriculture. It cannot be resolved without considering the issue of water metering and water distribution. The main task of the water accounting system in irrigation and drainage systems is measuring the volume of water taken from the water intake and delovered to the irrigation network. For these purposes, flow meters – devices that measure the flow of water, are used. Ultrasonic (acoustic) flow meters are flow meters capable of solving complex problems in flow measurement. Currently, there are several measurement methods to determine the water flow rate at reclamation facilities: ultrasonic, radar, Doppler method, cross-correlation method and Transit-Time method. Based on these methods, a large number of modifications of devices for determining water flow rates have been created: level gauges, radar flow meters, Doppler flow meters, submersible cross-correlation flow meters, pulse-time flow meters. Conclusions. Flow meters based on level gauges and radar flow meters are impractical to use in commercial water metering units. They have high flow measurement errors, since level gauges measure only the level, and the speed is taken as a constant value, while radar flow meters measure the flow rate, but this is not the speed of the entire flow, but only of the surface layer. The flow rate measured by Doppler and cross-correlation meters depends on the amount of solids in the flow. But since the water in canals and closed pipelines on irrigation and drainage systems has a large number of solids, these flow meters have a high accuracy of flow measurement. Pulse time meters, as well as Doppler and cross-correlation meters, have high measurement accuracy, but do not depend on the amount of solids in the flow.

Materials and methods. The theoretical and empirical basis for the development was made up of well-known recommendations on design and construction of pond complexes and survey data of operating fish-breeding facilities and their structures. During the development, the technologies of search design of engineering projects in compliance with fish breeding requirements and restrictions were used. Results. The fish-breeding complex includes: two fish-breeding ponds with a common dividing dam and a water supply system including a pumping station; water supply pipe system; a system of devices and structures that ensure the release of fish grown in ponds into a fish trap; spillway devices for discharging water from ponds and a fish trap with a set of regulating elements. Fish ponds are located on the floodplain lands of the river Don and are formed by protecting dikes. The bed of the reservoirs is planned with sections with longitudinal and transverse slopes to the water-fish collecting and-transporting ditches arranged in their bottom, allowing them to be emptied and the fish grown in the ponds to be directed to the outlet structures. The release of fish from the ponds is carried out by two tower water outlets. The design of the fish trap provides for the accumulation and seine fishing, it is equipped with means for regulating water discharge and maintaining conditions for fish. Conclusions. The developed layout and design solution for a two-pond fish-breeding complex with one fish trap is adapted to the local relief and the difference in water levels in ponds and in water intake. The implemented layout and design solutions can be used in the development of similar objects

Afanasy Afanasyevich Fet as a poet-thinker
Authors: Fedorov Alexey V.
Published: December 2020

The article proposes to consider the creative individuality of A.A. Fet as a poet-thinker. It places a special emphasis on his ideological views, expressed in his enthusiasm for the teachings of A. Schopenhauer’s and in disputes with L.N. Tolstoy; extensive epistolary material is involved (this correspondence with Ya.P. Polonsky, L.N. and S.A. Tolstoy, N.N. Strakhov, K.R. and others); a brief overview of the critical reviews of contemporaries on the poet’s poetry collections is given. Here, Fet’s philosophical lyrics are analyzed in particular detail (first of all – the late, period of “Evening Lights”, in which there is an understanding of the universal categories of being – life and death, good and evil, the world and man, time and eternity), some parallels are drawn with F.I. Tyutchev. The article traces the development of spiritual and religious issues in the work of Fet’s (gospel stories and motives, the image of the Lord, the genre of prayer, etc.). The article raises the question of expanding the concept of “poet-thinker” taking into account the category “mind of the heart” designated by Fet himself. From these positions, his poem “I am waiting, embraced by anxiety...” from the “Evening Lights” collection is analyzed. Considering Fet’s work as “the poetry of thought” does not cancel, but enriches his airy image in our minds, allows us to present Fet’s personality in more volume, to clarify and expand the idea of the real complexity and versatility of his artistic nature, to come closer to understanding “lyrical insolence” as “the property of great poets” (words of L.N. Tolstoy about A.A. Fet).

It justifies the need for the state to pursue a social policy as the implementation of a function to combat social risks in modern society, in particular with the risk of old age. In the course of the study, key features and methods of state influence on pension legal relationships at each of the three levels of the Russian pension system were identified, and problems in the implementation of its state regulation, which includes the formation of a legislative base, control and supervision and distribution functions, were shown. The difficulty lies in the fact that state regulation of the pension system is carried out in conditions of limited financial resources, which leads to halfness of the decisions, adoption of populist measures and contradictions between current and long-term tasks. However, there is no alternative to state regulation, since only state regulation is able to balance the interests of all participants in the pension system.

Lobbying is essential part of a democratic society and it is impossible to deny its existence in modern Russia. Despite that fact, Russia had not officially recognized the existing phenomenon, and the relations in this area had not been regulated by law. Examine the experience of other countries and comparing it with known manifestations of lobbying in Russia, it is necessary to relate it to known models. This will make it possible to identify the state of development of this institution in our country, avoid the specific errors of the system, predict the possible direction of development and improvement of this mechanism. The study of the phenomenon of the emergence of vested interests, their place in the political system, as well as the concept of ‘lobbyism' and the mechanisms of its legal regulation led to the conclusion that a model of state corporatism has developed in Russia, and a continental model of the legal regime-regulation of lobbying. Research had revealed the need to improve and establish new institutions for the articulation of group interests, the adoption of a law on lobbying and the establishment of a public register of lobbyists.
Algorithmic transparency and bureaucratic discretion: The case of SALER early warning system
Authors: Criado J. Ignacio , Valero Julián , Villodre Julián
Published: December 2020

The governance of public sector organizations has been challenged by the growing adoption and use of Artificial Intelligence (AI) systems and algorithms. Algorithmic transparency, conceptualized here using the dimensions of accessibility and explainability, fosters the appraisal of algorithms’ footprint in decisions of public agencies, and should include impacts on civil servants’ work. However, although discretion will not disappear, AI innovations might have a negative impact on how public employees support their decisions. This article is intended to answer the following research questions: RQ1. To what extent algorithms affect discretionary power of civil servants to make decisions?RQ2. How algorithmic transparency can impact discretionary power of civil servants? To do so, we analyze SALER, a case based on a set of algorithms focused on the prevention of irregularities in the Valencian regional administration (GVA), Spain, using a qualitative methodology supported on semi-structured interviews and documentary analysis. Among the results of the study, our empirical work suggests the existence of a series of factors that might be linked to the positive impacts of algorithms on the work and discretionary power of civil servants. Also, we identify different pathways for achieving algorithmic transparency, such as the involvement of civil servants in active development, or auditing processes being recognized by law, among others.
Interactive effects between monetary policy and fiscal policy based on dynamic stochastic general equilibrium model
Authors: Xie Ying
Published: December 2020

From the beginning to the end, monetary policy has focused too much on the control of the supply side. At present, the single supply-based monetary policy is ineffective. Therefore, it is urgent to change the current single direct supply-side regulation and control policy and replace it with a non-single and indirect control policy that combines supply and demand. Based on machine learning algorithms, this paper constructs a monetary policy analysis model based on dynamic stochastic general equilibrium methods to analyze the interactive effects of monetary policy and other policies. Moreover, this paper uses the dynamic stochastic general equilibrium model to simulate and analyze the economic effects of fiscal policy. In addition, this paper compares the economic effects of monetary policy and other policies and conducts verification and analysis through actual data. The obtained results show that the model constructed in this paper achieves the expected effect.

Published: December 2020

In marketing, problems such as the increase in customer data, the increase in the difficulty of data extraction and access, the lack of reliability and accuracy of data analysis, the slow efficiency of data processing, and the inability to effectively transform massive amounts of data into valuable information have become increasingly prominent. In order to study the effect of customer response, based on machine learning algorithms, this paper constructs a marketing customer response scoring model based on machine learning data analysis. In the context of supplier customer relationship management, this article analyzes the supplier’s precision marketing status and existing problems and uses its own development and management characteristics to improve marketing strategies. Moreover, this article uses a combination of database and statistical modeling and analysis to try to establish a customer response scoring model suitable for supplier precision marketing. In addition, this article conducts research and analysis with examples. From the research results, it can be seen that the performance of the model constructed in this article is good.
Analysis of heterogeneity of inflation expectation based on genetic algorithm and time series model
Authors: Tan Haoyang , Zhang Qiang
Published: December 2020

The heterogeneity of inflation expectations, especially the residents’ inflation expectations, has a great influence on controlling the actual inflation rate and the effective implementation of my country’s monetary policy. In the process of monetary policy formulation, the monetary authorities need to pay more attention to the heterogeneous expectations among microeconomic individuals. This paper introduces the genetic algorithm, a new artificial intelligence method, to analyze the demand for the heterogeneity of inflation expectations and explains the basic steps to use it and how to apply it to explain problems in economics. Moreover, this paper uses a genetic algorithm-based generation overlap model to simulate the dynamic evolution of inflation heterogeneity among residents and the equilibrium selection process of price levels in a wide search space. The results of the simulation experiment show that it is of practical significance to use genetic algorithms to simulate the dynamic process of the heterogeneity of residents’ inflation expectations.

Published: December 2020

The regional real estate price bubble regulation policy is an external factor for the real estate industry. The effect of real estate regulation is difficult to determine, which is a typical problem of uncertain system analysis and forecasting, and the gray Bayesian network forecasting model is to solve the forecasting problem of economic system subject to external regulation. Based on machine learning and factor analysis models, this paper constructs a real estate bubble financial risk analysis model based on machine learning and factor analysis models. Moreover, starting from the real estate price bubble, which is a hot and difficult issue of the social economy, this paper discusses the causes of the formation of real estate price bubbles and the mechanism of the formation of real estate price bubbles, looks for the importance of policy regulation of real estate price bubbles, and clarifies the functional game model of policy regulation of real estate price bubbles. In addition, this paper uses examples to study the model constructed in this paper. The results show that the model constructed in this paper has a certain effect.
Lyapunov approach based design of a gain adaptive interval type-2 fuzzy controller for servo systems

Published: December 2020

This paper focuses on the development of a stable Mamdani type-2 fuzzy logic based controller for automatic control of servo systems. The stability analysis of the fuzzy controller has been done by employing the concept of Lyapunov. The Lyapunov approach results in the derivation of an original stability analysis that can be used for designing the rule base of our proposed online gain adaptive Interval Type-2 Fuzzy Proportional Derivative controller (IT2-GFPD) for servo systems with assured stability. In this approach a quadratic positive definite Lyapunov function is used and sufficient stability conditions are satisfied by the adaptive type-2 fuzzy logic control system. Illustrative simulation studies with linear and nonlinear models as well as experimental results on a real-time servo system validate the stability and robustness of the developed intelligent IT2-GFPD. A comparative performance study of IT2-GFPD with other controllers in presence of noise and disturbance also proves the superiority of the proposed controller.
