Published: August 2022

Sediment is a collection of particles that come from weathering both soil and rock, biological and an anthropogenic process. Sediment flows from upstream to downstream areas. Topographic conditions are one of teh factors in sedimen distribution. The topography in the Wonorejo area tends to be low because it is located in a coastal area. The purpose of this study is to determine the effects of topographic changes in Wonorejo on the distribution of sediments in the area. The method used in this study is descriptive method by collecting data including primary data and secondary data. The primary data used are Landsat 7 and Landsat 8 satellite imagery, while the secondary data used is in the form of Surabaya village administration map data, Surabaya DEM data and Indonesian SHP data. Data processing was performed using ArcGIS 10.3 software. The results indicated that the topographic conditions of the region did not have a significant influence on the distribution of sediments in the Wonorejo area. The distribution of sediment in those area was more influenced by hydro-oceanographic factors such as currents, tides and waves. Other factors that influence are anthropogenic factors such as development and land conversion

Published: August 2022

Oil pollution in the waters is one of the factors that affect the abundance of phytoplankton, especially the diatom. The waters of Lalang Strait, Mengkapan Village, are used as international shipping lanes and industrial areas. The research was conducted in the Waters of Lalang Strait Mengkapan Village, Siak Regency, Riau Province. The research was conducted at 3 stations with different location characteristics. Station 1 is near Tanjung Button Port, station 2 is in the mangrove ecotourism area, and station 3 is in the fishing port and near the settlement. The result of oil content analysis obtained an average value of 0,00016 ppm. The highest oil content at station 3 is 0,00035 ppm and the lowest at station 2 is 0,00011 ppm. The results of the calculation of the abundance of planktonic diatoms ranged from 5.014 to 22.062 cells/l. The highest abundance at station 1 was 17.716 cells/l. The lowest abundance was at station 2 which was 9.694 cells/l. Simple linear regression test result, obtained equation Y= 14,2644+(-3802,27x). The coefficient of determination (R2)= 0,002 states 0,2 % of the abundance of planktonic diatoms is influenced by oil content and the rest is influenced by other environmental factors. Correlation coefficient (r) = 0,053, so the relationship of total oil content with the abundance of planktonic diatoms is very weak

Pearl catfish has the main advantage of fast growth. To maximize this growth, one of the things that must be considered is the feed given. The use of factory feed for catfish seeds is common, so it is necessary to use feed raw materials that are around to be used as raw materials for homemade feed. Vegetable waste such as cabbage and tofu dregs can be used as fish feed which is processed into pellets. Cabbage vegetable waste, tofu dregs, bamboo shoots and bran have protein and carbohydrates that can be used for fish growth. This study consisted of 2 stages, namely stage 1 analyzing the comparison between factory feed and homemade feed and stage 2 analyzing the difference in dosage of homemade feed on the growth and efficiency of pearl catfish (C. gariepinus) seed feed. Data were analyzed using 2 independent samples (unpaired) t-test and ANOVA test. The results showed that the provision of factory feed and homemade feed did not have a significant effect on the growth of length, weight, and feed efficiency of catfish fry. Catfish seeds can be fed homemade feed with ingredients from fermented cabbage waste, tofu dregs flour, rebon flour, bran flour, plus vitamins and minerals. The results of the analysis of variance in the treatment of different feed doses (4%, 5%, 6%, 7%, and 10% per fish body weight), had a significant effect on the growth of catfish length and weight, and had no significant effect on feed efficiency. The higher the dose given for the maintenance period of 30 days of catfish fry gave a good effect with the best dose of 10% per fish body weight

Although this article is more like scientific fantastic, the creation of “talking” dogs through genetic engineering cannot be ruled out in the near future. The transcription factor FOXP2, which is responsible for communication abilities and articulate speech in humans, may become a key target. This protein is very conservative and differs in different organisms by single amino acid substitutions. FOXP2 of humans and its closest relative chimpanzees differ by two amino acids, while humans and dogs differ by only one amino acid (p.N303T), caused by a single nucleotide substitution, which can be corrected using CRISPR/Cas genome editing technology. Attempts to create talking dogs can make a significant contribution to the development of research on the effects of normal and defective human FOXP2 genes. In this case, dogs may serve as a more suitable model object for this kind of research. Of greatest interest in terms of giving the ability to talk to dogs are breeds of companion dogs, as well as decorative breeds due to their greater demand and accordingly commercial attractiveness. The barking of dogs, which is practically not used by their wolf ancestors, can be considered a kind of independent attempt by dogs to establish communication with humans during domestication. Undoubtedly, the appearance of talking dogs will entail the development of new bioethical principles.

Goal Substantiation of the theoretical basis on the directions of improving the formation of the financial support mechanism of social services in terms of general trends in the development of the financial mechanism of social services based on international experience. Method. The analysis of the formation of the mechanism of financial support of social services is based on the methods of theoretical generalization, grouping and comparison. Results. Emphasis is placed on the problem of developing methods of forming effective social instruments in the modern economy of Ukraine, which is manifested in promising areas of improving the formation of the financial support mechanism of social services. A comparison of the definition of the term "financial security mechanism" is performed. It is argued that the system of the mechanism of financial provision of social services of Ukraine has excessive social obligations of the state, which are not supported by real financial resources. Reasonably, the category of "financial security" can be considered as a component of the financial mechanism, which is aimed at the formation of financial resources and their use through and in the activities of various entities. The process of financial provision of social services is proposed, which can be divided into two stages: the formation of financial sources and the use of financial resources. Emphasis is placed on the fact that the budgetary mechanism, as a component of the financial mechanism, regulates the process of financial provision of social services, in view of this, the financial methods of social security are defined. The connection between the specifics of social services and the peculiarities of the financial provision mechanism is analyzed. The main directions of improvement of the mechanism of financial provision of social services are offered, which should be considered on the basis of international experience from the point of view of formation as much as possible not only from the financial incentives connected with subsidies through target intergovernmental transfers. social services. Scientific novelty. The expediency of optimizing the mechanism of financial support of social services through the optimization of a set of tools for regulating financial relations in this area is substantiated. Practical significance. The results of the study form a scientific and practical basis for conducting various analytical and forecasting studies in terms of substantiating the optimal directions for further innovative development of the mechanism of financial support of social services based on international experience.

Development of theoretical and methodological basis for analysis of economic efficiency of regional landscape parks based on determining the level of capacity in terms of taking into account the interests and requests of visitors, seasonality factors and environmental and economic characteristics of the protected area. The proposed scientific and methodological approach to substantiation of the capacity of the regional landscape park is designed to use the theory of statistics, the law of normal distribution of random variables, methods of analysis and synthesis, comparison, general and comparison. It is substantiated that the management of all protected areas has a positive effect on visitor issues, which provide growth sufficient for the financial stability of the economy, economic independence, self-sufficiency of RLP, and do not affect biodiversity in RLP. It is shown that the income of this enterprise is a justification for filling cash flows, which provides expanded reproduction of natural components of RLP in the territory, allows for self-financing measures to restore the natural resource potential of visitors in developing and implementing new services for tourist cars. It is concluded that in the aggregate the justification of the capacity becomes the basis for the development of strategic plans for the development of RLP and the strategy of socio-economic development of the region as a whole. The proposed author's methodology is based on seasonal factors, the level of demand for tourists and visitors in the consumption of services offered by the regional landscape park, the list of economic activities and the capacity of the protected area provide the maximum number of people visiting the park per unit time. Based on the results of practical use of the proposed methodology, the state and territorial economy can develop an effective strategy for socioeconomic development, increase the effectiveness of the current strategy and ensure the objectivity of management tools for planning and regulating economic activities of regional landscapes

. The issues of optimization of the composition of energy sources and storage units in hybrid autonomous microgeneration systems are considered. The development of renewable energy, namely its decentralization and autonomy, is today the main issue in the energy sector. At the same time, it is a solution to the problems of an increasing level of electricity consumption and an increase in carbon dioxide emissions into the atmosphere during electricity production. The introduction of small-scale power generation, namely autonomous microgeneration systems, is an extraordinary task that needs an immediate substantiated solution. The use of one type of power supply in stand-alone systems is unreliable and inefficient. In the process of evolution of autonomous systems, so-called hybrid systems have appeared, using several power sources with different principles of generating electricity. The article presents a new approach to the classification of hybrid autonomous systems based on the degree of hybridization of its components. Justification of the optimal composition of a hybrid autonomous microgeneration system, namely the optimal composition of sources and storage of electricity, is closely related to the determination and optimization of its operating modes. An integrated approach to optimizing the composition and operating modes of an autonomous microgeneration system with renewable energy sources and active consumers of electricity is considered. The algorithm developed in the article for a comprehensive substantiation of the composition and operating modes of a hybrid autonomous system is based on the calculation and comparative analysis of the energy characteristics of the hybrid components of an autonomous system, taking into account the needs of power supply of a particular consumer and with reference to the climatic conditions of its location. On the basis of the analysis, the structure of the optimal hybrid autonomous microgeneration system is proposed, which has high energy performance due to the rational choice of the installed capacities of generating and accumulating sources. The system has a high level of reliability and environmental friendliness, which is an important aspect of the development of decentralized energy. For the proposed structure, an algorithm for controlling the operating modes of a system with renewable hybrid energy sources and a hybrid energy storage system has been developed. A mathematical model of the proposed hybrid autonomous microgeneration system is presented.

An important factor in improving the energy efficiency of the electric arc steelmaking furnace (EAF) is utilization of the flue gas energy to preheat the initial charge. Implementation of the process in existing EAF requires the measures to synchronize with the carbon monoxide post combustion and to prevent of the toxic PCDD/F formation when conventional scrap heating, which is significantly complicated in a traditional scheme of CO afterburning with a single-stage air inflow through a temperature and concentration factors. The technological basics of medium-temperature scrap preheating by EAF flue gas have been developed and substantiated. Numerical study of carbon monoxide burning thermodynamics and kinetics shown that implementation of two-stage inflow of air into postcombustion chamber for stoichiometric combustion of CO and cooling the heat carrier provides a comprehensive solution of mentioned problems. The ratio of primary and secondary flows 1 to 3.5 provides allowable concentration of carbon monoxide in the ducts; obtaining gas mixture with a temperature of up to 500 °C, which prevents PCDD/F formation; acceptable temperature operating conditions of bag fabric filters of the gas cleaning system within 100 °C regardless of scrap preheating. Numerical simulation of the heat exchange process between the charge layer and the gaseous heat carrier reveal that shredder scrap of standard bulk density 0.9 t/m3 and mass of half EAF capacity can be preheated up to temperature of 450 °C in 18-20 minutes. Given value corresponds to the duration of technological period in the EAF heat cycle, characterizing by comparatively stable emission and maximal temperature of the flue gas flow. Reduction of the scrap fragments bulk density and the average size, as well as increasing the ratio of the heating chamber height to its diameter in the range from 0.7 to 2.0, promotes the heating rate magnification. The technology provides specific energy savings within 20-30 kW.h per ton of steel and can be implemented in existing electric steelmaking shop of the mini-mill without additional CO2 emissions. The payback period for a 50-ton EAF with annual productivity of 400-450 thousand tons of steel is 14-18 months.

The article identifies the main measures for energy saving, among which the need to develop and implement methods and devices for reactive power compensation. It was noted that the sign of energy systems of industrial enterprises is irrational management of reactive power flows, the presence of a wide range of harmonic oscillations in the network, violation of temperature modes of individual components of electrical equipment, which leads to reduced equipment life, increased costs. The main reasons for the low value of the power factor in energyintensive industries are the presence and use in technological processes of a large number of induction motors, the power factor of which according to passport data is 0.8 under nominal operating conditions. It is noted that in practice there are often cases when the engines run in modes other than nominal - they are underloaded or overloaded, there are frequent starts of engines under load and their long operation at idle. These modes of operation of induction motors are characterized by an increased level of reactive power. The low value of the power factor leads to increased losses in the conductors, which are directly proportional to the "square" of reactive power, which requires the use of conductors of increased cross-sectional area. The paper proposed design solutions for energy saving in existing technological schemes of power supply: by analyzing the existing situation and calculating the real value of the power factor were calculated and selected reactive power compensation units.
