Authors: Stanislavskaya Ekaterina B. , Melnikova Elena I. , Fedorova Arina R. , Danyliv Maksim M. , Vasilenko Olga A.
Published: November 2020

The annual increase in the production of protein-sensitive dairy products leads to an increase in the available amount of their by-product of production – whey. A promising direction in the implementation of its biotechnological potential is the production of a protein imitator of the fat properties – whey protein microparticulate. The aim of this work was to study the possibility of its use in the technology of semi-hard cheeses. The introduction of a fat simulator in a normalized mixture changes its composition, including the ratio of protein fractions, the ratio of fat to protein, and calcium content. With a mass fraction of microparticulate more than 10 %, a flabby clot forms, which is extremely difficult to undergo further processing to obtain elastic cheese grain. High hydration of whey proteins increases the moisture content in the cheese mass after pressing and in the ripening process. Hydrolysis of paracasein and its fractions proceeds more intensively in the cheese with fat simulator. The developed product is characterized by a higher value of the moisture content, which, together with the preservation of the protein clot particles of the simulator by the mesh structure, increases the yield of cheese.

Published: November 2020

The paper considers the experimentally confirmed data on marl efficiency in the zones with increased level of radionuclides in the soil (5–10 and 15–40 Ki/km2) in the last third of female pig pregnancy in the amount of 2.0 % of the diet dry matter. Feeding with local mineral supplement increases the reproductive functions of breeding pigs, in particular, the number of stillborn piglets decreased by 1.64–7.70 % and their safety to weaning increased by 4.8–11.9 %. The increase of redox and metabolic processes in the animal body of the experimental groups positively affected the milking capacity of the breeding stock increasing it by 6.8–21.9 % and the growth of piglets, which was confirmed by their larger body weight by 3.3 and 4.6 %. The sorption properties of marl allowed reducing the concentration of toxic lead in the body of breeding pigs (by 40.17 and 42.01 %) and cadmium (by 20.57 and 24.42 %), decreasing the transition of cesium-137 isotope to beestings milk by 1.34 and 1.28 times. In areas with high soil pollution with radiocesium in Bryansk region, the use of natural marl sorbent in breeding pigs’ diets activates their immunity, hematopoietic functions, accelerates assimilation of protein and mineral exchange.

Published: November 2020

Antibiotics widely used in poultry farms can have a harmful effect on meat consumers through chemical residues. Thus, it is important for the safety of customers to find a natural alternative. The purpose of this study was to evaluate the effectiveness of adding a poly-enzyme preparation “Universal”, containing amylosubtilin (1300 U/g), protosubtilin (67 U/g) and celloviridine (2000 U/g), on the productivity of broiler ducklings of the Cherry Valley breed. The results of research have shown that the addition of the “Universal” drug in the diet helped increase the meat productivity of broiler ducks. The use of the “Universal” drug contributed to the better development of internal organs (heart, liver and stomach) in broiler ducks. The improvement in duck weight and meat yield may be attributed to the fact that the feed protein is best consumed under the influence of protosubtilin, one of the “Universal.” It is understood that protosubtilin supplies digestible peptides and amino acids with hydrolysis of plant proteins from grain raw materials, enhances the gastrointestinal tract’s enzymatic history, compensates for the loss of depleted digestive enzymes and at the early stages of animal growth. Thus, the results of the experiment showed that the use of the drug “Universal” in the cultivation of broiler ducks of the cherry valley breed increases the pre-slaughter and slaughter weight, meat yield and reduces feed conversion, which is economically profitable. Therefore, it is recommended to use the drug “universal” as part of ration for broiler ducklings.

Published: November 2020

The study was carried out in the Republic of Tatarstan (Volga Federal District of the Russian Federation) in grey forest middle loamy soil with weak acid reaction of the medium, low humus content, increased content of labile forms of phosphorus and potassium. The soil was deliberately contaminated with oil at a dose of 25 l/m2. There is close positive linear relationship (R2=0.845) between the amount of bens(a)pyrene (BP) and petroleum substances in soil. The BP content in oil-contaminated horizons (0–15, 15–30, 30–45 cm) of soil exceeded the maximum allowable concentration by 10.5–19.5 times that demonstrates a serious threat to vegetable products growing on oil-contaminated lands. Due to oil contamination, the content of most labile forms of nutrients (N, P, K, B, Mo, Zn) decreased and others remained unchanged (Cu, Co) or increased (Mn). At the same time, these changes were not so significant, because the groups of soil supply with labile forms of nutrients, except phosphorus and potassium, did not change under the influence of oil.

Published: November 2020

The paper presents the results of preclinical studies of the allergenic properties of a new drug bisphenol-5, which has pronounced anti-radical activity. An experimental study of the antioxidant was carried out in doses of 2, 5, 20 mg/kg in guinea pigs and rabbits. It was shown that bisphenol-5 is not able to cause a general anaphylaxis reaction (anaphylactic shock). By the method of skin applications, the absence of allergenic effects of the drug in animals was found. During the formulation of conjunctival tests in experimental and control animals, signs of hypersensitivity, both immediate and delayed, were not observed with respect to the test drug. Changes in body temperature, pulse rate, and the number of respiratory movements as a result of clinical studies of the state of the animal organism after applying bisphenol-5 were also not recorded. Thus, the drug Besphenol-5 in the studied doses and under the selected experimental conditions does not have a negative effect on the body of laboratory animals and does not have allergenic properties.

The purpose of this work is to study the fundamentals of doing business in the form of small businesses in the Russian Federation, the general goals of state support for small businesses, identifying the main problems of agricultural producers in the countryside, and developing recommendations for solving existing problems in the framework of developing small and medium-sized businesses in country. Agricultural entrepreneurship in Russia began to develop actively in the 1990s; at present, due to the not very favorable economic situation in the country and in the world in general, entrepreneurship in agriculture is going through difficult times. The main reasons for this state of affairs can be considered the lack of funds from producers for the material and technical supply of their production, the lack of domestic and foreign investors in this risky industry. Also, with a change in the dollar exchange rate, it is difficult for entrepreneurs to purchase expensive foreign equipment and many other tools that are necessary when doing business, all these factors substantiate the relevance of this study: the need to increase the level of state assistance to small and medium-sized enterprises. The practical significance of the study consists in the development of certain measures for the organizational and economic development of small agribusiness and its support from the state.
Efficiency of using Vitaferm in broiler poultry farming
Authors: Reznichenko Aleksei
Published: November 2020

The cultivation of poultry without the use of antibacterial drugs is a vital direction of modern production, since the entry of domestic poultry products to the foreign market involves their absence in raw materials of animal origin. As experience confirms, enrichment of feed rations with enzyme preparations and vitamins reduces the waste of young animals, significantly increases the feed absorption, and reduces their feed-gain relations per production unit. This allows enhancing the productivity of poultry farming while simultaneously improving the quality of resulting products. We have studied the effect of the new vitamin-enzyme complex Vitaferm on the broiler-chickens body against the background of the antibacterial drugs exclusion from their antiepizootic measures. Studies have shown a positive effect of Vitaferm on the poultry body which is manifested by an increase in average daily growth, livability enlargement and reduced feed-gain relations per production unit. These changes can be explained by the normalization of the digestive system of broiler-chickens with the Vitaferm use. It is known that antibiotics inhibit the body’s immune system and disturb the balance of intestinal microflora. Thus, the use of vitamin-enzyme complex Vitaferm with broiler-chicken feed at the rate of 15.0 g/kg, starting from the day-old up to 10 days, is proposed for the complete or partial exclusion of antibacterial drugs from the antiepizootic measures scheme.

Currently, there are a lot of applications of vortex technologies. The vortex effect is used in gasdynamic cold generators and vortex cooling chambers. Vortex devices are also used as dehumidifiers, separators, for cooling and heating hydraulic fluids, separating two-phase media, gas mixtures, evacuating, etc. Scientists study the applicability of vortex equipment for traditional and freeze-drying of agricultural products. However, the influence of geometric parameters of vortex devices on the productivity and energy efficiency of temperature separation of gas flows is poorly studied. Research aimed at finding opportunities and expanding the field of application of vortex tubes is an urgent task. The paper describes twodimensional and three-dimensional mathematical models of the swirling gas flow arising in a vortex tube. It presents results of its implementation in the Anсs-Fluent software package. Thermodynamic and hydrodynamic characteristics confirm the effect of temperature separation in a vortex tube. The dependences of temperature separation on the swirl angle and inlet pressure were obtained. For a two-dimensional vortex tube model, calculations were carried out using various turbulence models. The influence of the cross-sectional area at the hot gas flow outlet on temperature separation was studied.

Published: November 2020

Due to high athropogenic loads on the environment, issues surrounding public health and safety in consumable products are being raised with ever-increasing frequency. One toxic metal, whose consumption results in irreparable harm to the health of animals and human is cadmium. To antagonize such toxic effects to human health, magnesium and zinc are considered being essential elements and their combination effects warrant further studies. To this end, we developed a Wistar rat model to look at the combinatorial effects of cadmium with magnesium and zinc consumption on the accumulation of iron and zinc ions in kidney and liver tissues. Our findings suggested that exposure to cadmium ions reduced zinc ion levels in the liver and kidneys, reduced iron ions in the liver (but were increased in the kidneys), decreased magnesium ions in the kidneys but increased their levels within the liver. Moreover, while the consumption of magnesium and zinc ions individually, partially reduced the effects caused by cadmium consumption alone, the simultaneous consumption of zinc and magnesium ions proved to be significantly more effective.

The relevance of the topic is due to the need to study features of the rural economic development in the current social and economic environment. The aim of the article is to develop recommendations for improving the efficiency of rural business by analyzing the current situation and identifying features of development of agricultural businesses. The article describes results of an analysis of characteristics of the development of sectors of the rural economy over the past seven years. It has been established that the annual growth rates of the economy of the Republic of Tatarstan in general and the agricultural sector, in particular, are decreasing. In the next five years, they may amount to only 1–1.5 %; in 2014–2016, GRP of the agricultural sector amounted to 11–12 %, in 2017–2019 – 10 %. According to the existing trend, its share may decline to 8–9 %; 50 % of the production volume are produced by small businesses, which have a strong influence on volume indicators and are characterized by growth instability depending on demand and price fluctuations in the market. It is necessary to create conditions for the stable functioning of large agricultural producers, take measures to create a system of agricultural consumer cooperatives and diversify the rural economy in order to achieve stable development of rural territories.
The effect of fertigation on salinization and stability of soil aggregates, taking into account the effectiveness of precipitation on their natural desalination in central Europe
Authors: Ziganshin Bulat , Galiev Ilgiz , Khusainov Rail , Abdelfattah Ahmed
Published: November 2020

The effect of fertigation on the physicochemical properties of soil was estimated. Three fertigation procedures with different salinity levels were tested. The effect of precipitation on soil desalination through salt leaching was controlled by comparing changes in soil electrical conductivity during and after vegetation. Soil aggregate stability was measured as an indicator of soil degradation. The electrical conductivity of soil during pre-sowing (or after sowing) treatment was higher than at the end of the growing season. This difference decreased significantly, becoming insignificant after winter due to the effective dissolving effect of rain and snow. The article considers the issues of natural soil desalination, taking into account precipitation. Studies of soil desalination by leaching of salts were described. It was revealed that in the short term fertigation is not harmful to the soil if the amount of precipitation is sufficient.

Published: November 2020

The article outlines the results of the research into the influence of feed composition on the amino acid value of African catfish meat. It has been shown that quality characteristics of fish meat depend on protein and fat content. It has been proved that high-protein feed ensures increase in the content of all amino acids in African catfish meat. Nevertheless, protein and fat content in the muscles of the studied fish is more than 2 times higher than the same indicator in the fish on low-protein and low-fat diet. Meat of the African catfish is rich in two amino acids – leucine and lysine. Two amino acids, tryptophan and methionine, are limitative at a high protein diet. At a lower protein diet, isoleucine amino acid is also added. The amino acid composition of African catfish meat is highest at high-protein feeds. The amino acid index of African catfish muscles at high-protein feeds is 0.48, significantly exceeding the index of fish bred on feeds with a reduced protein content. The conducted studies have shown that the use of high-protein feeds in catfish breeding stimulates protein metabolism, enriching the amino acid composition of muscle tissue and increasing the nutritional value of fish as a food product. The research has been funded by the Russian Foundation for Fundamental Research, project No. 18-016-00127.

Published: November 2020

The impacts of climate change in the last decade are tropical storms, rising sea levels, and forest fires. These impacts damage human health, natural resources, and gender equality. This study aimed to identify the effects of climate change in the community, cultural development, and gender roles in addressing climate change in Central Kalimantan. This study used a cross-sectional design with questionnaires. Data collection was carried out using interview and observation techniques with a purposive sampling method. Interviews were conducted with 30 respondents in each district. The results of the study showed that the community has long felt climate change in Central Kalimantan. Still, they do not yet understand that changes in rainfall and temperature patterns reduce environmental conditions and forests’ function to support daily life. The openness of access to natural resources for women gives the responsibility of maintaining families during climate change, for example, utilizing plants to be used as weaving material in managing wet and dry forest ecosystems that increase deforestation rates. In the future, stakeholders, including regional government, will issue policies that protect women’s rights and interests to ensure that women get the same access and benefits related to information and decision-making, especially in natural resources management.

Published: November 2020

As one of the sustainable food, hydroponic vegetables begin to attract consumer attention. Previous studies focus on how to increase the willingness to pay (WTP). The cost of growing hydroponic might cause it as higher than traditional (soil agriculture) that drives higher prices. Instead of only focus on WTP, attitude and purchase intention are two constructs that important to estimate actual purchase behavior. However, a study about the antecedents of hydroponic vegetable’ purchase intention is still limited. This study aims to identify factors that can enhance purchase intention, group respondents based on those factors, and profile each respondent’s group. By online survey, 981 respondents were collected, and multiple regressions and cluster analysis analyzed further data. The result shows eight factors that could drive purchase intention (attitude, subjective norm, perceived behavioral control, perceived quality, price, availability, health consciousness, and knowledge), while environmental concern was not significant. Cluster analysis generates 3 clusters of respondents that have different profiles based on all factors and demographics variables. This study contributes to portraying respondents’ responses toward hydroponics that could deliver implications for entrepreneurs or marketers to attract target consumers based on all factors and develop a strategy based on their profiles.

The curtailment of infectious diseases is facilitated through observance of good hand hygiene, a habit which tends to be low less observed in developing countries. This paper investigated the level of availability and adequacy of water, sanitation and hygiene (WASH) materials in secondary schools in Lagos State, Nigeria. The sample size is made up of 620 respondents, selected through a combination of purposive, stratified, and simple random sampling methods. Research instruments adopted included questionnaires, focus group discussion guide, document observation, and unobtrusive observation. Quantitative data were analyzed through the Statistical Package for Social Sciences (SPSS). The study showed that the majority of the respondents (87.4%) admitted that the most typical type of toilet facility is a water closet, followed by pit latrine (13.7%) and open space (1.6%) for defecation. A majority of the respondents considered the provision of a wash hand basin as grossly inadequate. Therefore, researchers recommended improvement of structures, facilities, and materials relating to WASH in schools across Lagos State, Nigeria.

Industrialization and the attraction of the city have generated urbanization from the villages to the big cities. The downgrading scheme can be seen through the agricultural sector which suffers several serious problems toward the increase of a mass urbanization, ageing society, and the decline of the young farmers’ population. The data of this research is analyzed with qualitative methods using content analysis of the literature studies. The explanation will be provided by analyzing what aspects which could make Workaway projects sustainable, including the cultural exchange form and the tourism attraction aspect. The projects mainly tend to focus in finding the workers using counterurbanization attraction of the tourism magnetism around the place. There are approximately 60 projects which are related to agriculture projects around Japan. The purpose of this research is to identify and explain how Workaway Project in Yufuin can provide the network between the local community and the international society to contribute in helping the local farmers. This research found that the project is helpful in solving part of the problems in Japanese agriculture in rural areas.

Straight-bladed Darrieus blade is a type of vertical axis wind turbine that requires low wind speed to operate but is considered less efficient due to conventional blade geometry. To increase its performance by means of dynamic torque, the study used a statistical method, central composite design, through DesignExpert software. The computational fluid dynamics (CFD) through SolidWorks Reynolds-Averaged Navier Stokes Equation (RANS) k – epsilon turbulence model was used to simulate the Design of Experiments. The study was composed of two phases, namely 2D and 3D simulations. The 2D simulation studied the effect of varying the camber, camber location, and thickness to the dynamic torque, while the 3D simulation varied the blade height, rotor radius, and materials. The camber’s optimal conditions, camber location, and thickness in 2D simulations are 4.75%, 45%, and 15.50% of the chord, respectively. These optimal design values could reach the dynamic torque equivalent to 60.6571 Newton-meter. Meanwhile, the blade height and rotor radius of the 3D simulations have optimal design values of 4.41 meters and 4.75 meters, respectively. These optimal values could increase the dynamic torque to 2310.01 Newton-meter. The dynamic torque of the optimal design obtained a 133% significant increase compared to the conventional blade. Thus, the research has proven the increase in the Darrieus Wind turbine’s performance by varying its blade geometry.
Oil spill detection in the east of Sri Lanka with Sentinel-1 SAR
Authors: Mahindapala W. Kamal M.
Published: November 2020

In September 2020, two major fires broke out in a large crude oil tanker in Sri Lanka’s maritime zones. An island with a vast sea area in the Indian Ocean, Sri Lanka, is prone to vessel sourced pollution. Crude oil can have a damaging impact on the environment, and therefore tracking the spill in the water is essential. Spaceborne sensors support monitoring oil pollution; however, optical sensors need clear skies for observation. The detection of pollution caused by vessels; in Sri Lanka’s maritime zones has previously been investigated by the author. This study examines the data collected by the Sentinel-1 satellite, whose sensing corresponds to the oil spill event, manually and using algorithms to detect the presence of oil spills. Two detected oil spill areas were measured to be 0.6 km and 1.4 km long. Further, in this study, the SAR sensor’s vertical signal transmission and reception mode produced acceptable results in detecting the spills and the vessel. Sentinel-1 SAR data is essential, in this case, to detect the presence of the oil spills and the vessels.

Environmental education during a pandemic is something that must be focused especially on natural disasters. One of the skills needed to solve natural disasters is Higher Order Thinking Skills (HOTS). The purpose of this study was to describe student HOTS to develop a Disaster Mitigation of Flood based on the Online Learning (DIFMOL) model. The research method used descriptive with data collection techniques using surveys. The results showed that the student’s HOTS score was still in the very low category (33.09). This makes DIFMOL need to be developed for students, especially in aspects related to HOTS, which are still weak for aspects of flood disasters. Environmental education innovation is important to improve students’ ability to overcome environmental problems. DIFMOL in this case, acts as an environmental education innovation related to the disaster that can be developed. This study concludes that students’ HOTS scores are still in the very low category and need improvement. DIFMOL is suggested to be developed in the next research.

To control environmental pollution, the Wastewater Treatment Plant (WWTP) plays a vital role in treating wastewater to comply with quality standards before being discharged into the environment. However, not all WWTPs have worked optimally, so the periodic evaluations must be carried out to determine problems and what efforts can be made to improve WWTP processing quality. This study aims to evaluate the Jababeka 1 WWTP, which functions to treat wastewater in Industrial Area 1 and Industrial Area 7, which are in the Jababeka Industrial Estate (KIJ). Evaluation is carried out by comparing the actual processing efficiency with the related literature. Evaluation is also carried out by simulating the process and operation of WWTP using STOAT software. STOAT is one of the WWTP system modeling software mostly used to predict the wastewater treatment plant’s performance. The test results show that for the efficiency of Jababeka 1, WWTP removal for parameters BOD, COD, and TSS are 90%, 93.02%, and 96.12%. Based on the data obtained, modeling based on sensitivity analysis was also carried out using STOAT software to determine the most significant WWTP performance parameters. It was found that the wastewater discharge was the most critical parameter affecting the removal efficiency of TSS and BOD.

Published: November 2020

Traffic accidents are the fundamental yardstick for road safety. In South Sulawesi, particularly the four road sections which become the main focus of this study are Jeneponto-Bantaeng, Bantaeng-Bulukumba, Bulukumba-Tondong, and Sengkang-Impa-impa. Topographic conditions in South Sulawesi generally have various surfaces, including road sections area of this study focus. These various topographical conditions cause a chance of a traffic accident to occur at a certain point on the geometric features of the road, either on a straight or bend road/ curve road, grad (+) or grad (-), or the influence of the average International Roughness Index (IRI) value of a road. This study aims to analyze significant road geometric features that determine the fatality rate of the traffic accident. The results obtained from this study are significant factors of geometric road features that statistically affect and determine the fatality rate of traffic accidents; namely road geometry, road gradient, and IRI value, or with the conclusion is that all predictor variables are significant factors in influencing fatality rate of the traffic accident.
