Published: October 2021

Abstract
The results of experimental studies to determine the values of cryoscopic temperatures of the following (commercial) fish species are presented: blue shark (prionace glauca), stellate stingray (amblyraja radiata), Pacific herring (clupea pallasii), Atlantic salmon (salmon) (salmo salar), pink salmon (oncorhynchus) gorbusha), West African mackerel (scomberomorus tritor), red salmon (oncorhynchus nerka), mullet (mugil cephalus), Far Eastern navaga (eleginus gracilis), muksun (coregonus muksun), sea pollock (theragra chalcogramma), white-bellied flounder (lepidopsetta bilineata), bluebore halibut (reinhardtius hippoglossoides), black sea red mullet (mullus barbatus ponticus), pike-perch (sander lucioperca), Pacific cod (gadus macrocephalus), scrub hake (hake) (merluccius bilinearis), sea bass (sebastes alutus), icefish (champsocephalus gunnari), lacedra yellowtail (seriola quinqueradiata), sardine (sardinops) (sardinops ocellatus), haddock (melanogrammus aeglefinus), pike (esox lucius), crucian carp (carassius gibelio). A wide range of values of cryoscopic temperatures of the studied objects confirms the need for their accumulation, systematization and classification. It is proposed to use the value of cryoscopic temperature as a classification factor necessary to unify and simplify the substantiation of the modes of their refrigerated storage.

Published: October 2021

Abstract
The paper is devoted to the problems of using modern digital technologies to manage the implementation of programs for the development of the regional economy’s agro-industrial cluster. An approach based on the use of intelligent (knowledge-oriented) information systems for analyzing the progress of program implementation is proposed. As a model for representing knowledge about the subject area, it is proposed to use the apparatus of the linguistic variable theory and fuzzy production rules, which makes it possible to take into account the high level of uncertainty inherent in the agricultural sector of the economy. The inference engine included in the information system is based on explicitly interpreted Mamdani’s procedure of fuzzy logical inference, which makes it possible to form explanations of the course of reasoning. The developed structure of the intelligent information system is a concretization and extension of the traditional one, taking into account the reflection of the specifics of the tasks of managing the implementation of programs for the development of the agro-industrial cluster. The preliminary results of the experimental operation of the research prototype of the developed system can serve as confirmation of the effectiveness of the proposed design solutions.
Landscape approach in assessing the bioresource potential of specially protected natural areas
Authors: Tymchuk N A , Potasheva Yu I 
Published: October 2021

Abstract
There are many different approaches to studying the structure and organization of natural ecosystems. Among those are: geomorphological, landscape and ecosystem. It is generally accepted that a landscape approach has the greatest resolution, completeness and hierarchical depth. Landscape consideration of natural-territorial complexes is a key to understanding the regularities occurring in typological and biogeocenotic structure of natural ecosystems of any rank. A landscape approach to forest areas involves considering a specific forest community along with other spatially adjacent areas that form a system of a higher rank in a specific geographic environment. Any forest area within the facies should be considered taking into account other biogeocenoses existing next to it, not only forest, but also others (bog, meadow, etc.). Landscape properties are determined in many respects by the type of forest and their biogeocenotic composition, configuration of stands, their size and spatial relationship. Typological structure of forests determines many aspects of forest management strategy. The resource potential of the territory, economic value and economic accessibility are directly related to it. Landscape characteristics of forest lands often determine the degree of their development and general level of forestry activities. Forest cover, swampiness, basis of erosion, slope, length, steepness and exposure of slopes, type of geochemical circulation are main interesting characteristics of forest landscapes. The listed number of characteristics is included in the forestry-biogeocenotic attributes in the study of natural-territorial complex.

Published: October 2021

AbstractWood pulp industry generates tons of lignosulfonate by-product waste every year. Rational utilization of lignosulfonates is limited due to non-uniform structure and complex chemical composition. However, presence of different functional groups allows for a broad range of industrial applications, including catalysis in polymer chemistry. Therefore, the aim of this study was to analyze structural composition of sodium lignosulfonate and its modified forms using Fourier transform infrared spectroscopy (FTIR). Sulfuric acid treatment of sodium lignosulfonate was hypothesized to enhance catalytic capacity of the original lignosulfonate by increasing the amount of sulfonic acid catalytic active sites inside the structure of the macromolecule. FTIR analysis identified structural features of the lignosulfonate-based catalysts and their catalytic potential was assessed via alcohol dehydration reaction. As a result, polymeric forms of lignosulfonate were successfully used as a carbon-based catalyst matrix.

Abstract
The article considers the classification of financial risks in order to determine their impact on the level of economic security of an agricultural enterprise. For this purpose, the assessment of the indicators of liquidity and financial stability was carried out on the example of a specific economic entity operating in the agro-industrial complex industry. In addition, the factors of the external environment are considered, which include natural conditions, production innovations, market conditions that determine the economic security of the agricultural enterprise. The results of the risk assessment indicate that the agricultural enterprise is on the verge of a critical risk zone in terms of financial stability. Thus, a timely assessment of financial risks helps to prevent the occurrence of threats to the loss of sustainable development by an agricultural enterprise.

The recommendations for support setting mine workings have been developed.
Contemporary global production and consumption of cocoa: an assessment
Authors: Gavrilova Nina G 
Published: October 2021

Abstract
The paper is dedicated to an analysis of the production of cocoa, which is a critical component for many sectors of the economy. Scientists on a regular basis identify new valuable properties of cocoa, and the scope of its application expands accordingly. Since the 1960s, the global production of cocoa beans has grown fivefold. The key areas of production of the crop include Africa, America, Asia and Oceania. The three countries that in 2019 accounted for almost 60% of the production were Ghana, Cote d’Ivoire and Nigeria. In 2019, the volume of the world market for cocoa and its derivatives exceeded $50 billion. Most of the produce is imported by the USA, UK, Netherlands and France. Prior to the beginning of COVID-19, it was forecasted that in 2020-2024 the market for cocoa and its derivatives would grow by an average of 5% per annum. The pandemic has dampened such expectations as productions chains have been disrupted. In Europe and America, the demand has fallen, but recent forecasts are more optimistic. Nonetheless, specialists disagree on the prospects of the industry. While some note great challenges that the industry faces, others count on the introduction of new technologies to kick-start the sector.

Published: October 2021

Abstract
The article presents the results of studying the problems of the quality of life of the rural population in the Krasnoyarsk Territory. A feature of the work is the conduct of research at the level of individual municipal districts of the region. In accordance with the research methodology, the authors formed an initial list of indicators of quality of life. Using the index method of data aggregation, quantitative indicators of the quality of life and its individual components were obtained for the rural population as a whole in the region, as well as within the municipal districts. The main results of the work: the rural population of the region lives in extremely unfavourable conditions. The most critical is the situation with the provision of the rural population of the region with teachers, consumer services, and the availability of infrastructure for child development and upbringing. The consumption of goods and services is low compared to the urban environment, there is a high level of rural unemployment (over 13%) and the general morbidity of the population (679 new cases per 1000 people annually). The share of living space provided with minimum centralized communal conditions does not exceed 27%, about 89.3% of the rural population have difficulties in obtaining high-quality medical services. For only 3 out of 44 municipal districts, the quality of life of the rural population can be defined as acceptable. Among the main proposals of the authors: revision of the system of redistribution of tax revenues by budgeting levels; increasing the share of regional budget expenditures on rural areas from the current 4.78% to 15%; creation of special institutional conditions for rural areas, through a special regional law and an interdepartmental regional development program.

Abstract
This article presents the results of the study to determine the effect of zeolite-mineral feed additives when feeding young Simmental cattle in the conditions of Yakutia. Scientific and economic experiments to determine the optimal norms of local mineral feed additives were carried out in the conditions of Central Yakutia. The experiment was performed on young bulls of the Simmental cattle breed during the age of between 12 and 18 months. The experimental animals were selected by the analog method, which took into account the indicators of age, live weight and clinical indicators. During the experiment animals were kept under identical conditions. The difference was that the experimental groups were additionally given a mineral feed supplement – hongurin in different doses and Kempendyai salt with the daily basic diet. Animals in the cold season were kept in a small cattle house, fastened. During the experiments the optimal rate of inclusion of a zeolite-mineral feed additive was established, which allowed to maximize the growth rates of live weight while maintaining all clinical and physiological norms of the body. Thus, at the end of the experiment the animals of the II and III experimental groups were heavier than their peers from the test group by 2.93% and 4.28%. As a result, the animals of the experimental groups reached a live weight of 382.5 and 385.3 kg versus 371.6 kg in the test group. Growth rate indicators in test group bulls equaled 564.44 g, and for bulls in the II and III experimental groups 630 g and 650.56 g, respectively (indicators are higher by 11.62% and 15.26%). Thus, the use of zeolite-mineral feed additives in feeding young Simmental cattle in Yakutia has shown efficiency.

Published: October 2021

Abstract
For a long time the domestic black-and-white cattle was systematically improved by adding the blood of the world’s best dairy breed – i.e. the Holstein breed. In 2002 a new Ural type of black-and-white breed was officially registered. In first heifers with live weight of less than 550 kg an average negative correlation of milk yield is observed, in the first heifers with live weight of 625 kg or more this correlation is low negative to an average positive. In cows a positive correlation between live weight and milk yield per lactation is noted, except for group of cows with a high live weight where this correlation is not established. It should be noted that along with an increase in live weight from 550 kg or less to a weight of 599 kg, the correlation between these signs decreased, but this correlation increased among the cows with a live weight of 600-624 kg. The correlation between live weight and milk quality parameters per lactations is also ambiguous and ranged from high positive (0.89, 1 lactation, weight up to 550 kg) to low negative (-0.19, 1 lactation, weight 625 kg or more) in terms of correlation between live weight and mass fraction of fat (MFF) in milk.

Abstract
Holsteinized black-and-white cattle are used for milk production. The genealogical structure of the herd is represented by animals from the following genealogical lines: Vis Back Ideal 1013485, Reflection Sovering 198998, Montwick Cheiftain 95679, Pabst Governor 882933 and Annas Adema 30587. Animals of these types feature high milk productivity indices. In particular, the cows of all the researched lines have high milk productivity indices - more than 9,000 kg of milk per lactation. The highest milk yields are achieved by cows of the Montwick Cheiftain 95679 line. The yields are 16-339 kg higher than ones of the animals from the Annas Adema 30587 and Pabst Governor 882933 lines, respectively. According to the quality indices of milk, cows of all lines exceed the requirements of the breed standard. Data on amount of milk fat confirms the level of breeding value of the cattle breeding stock used in the farm. They exceed the breed standard in terms of milk fat yield by more than 2 times. The highest coefficient of the cows’ biological efficiency was recorded in the cows groups of Annas Adema 30587 and Montwick Cheiftain 95679 lines, and the biological full-value was confirmed for the Montwick Cheiftain 95679 and Pabst Governor 882933 lines.

Published: October 2021

Abstract
The article presents the results of a study of the amino acid and fatty acid composition of the liver of Arbor Acres broilers, which were fed with ultrafine particles of silicon dioxide at a dose of 100, 200, 300 and 400 mg per kilogram of mixed feed. It was found that the use of UFP SiO2 in the cultivation of broilers contributes to an increase in the liver of poultry I-IV experimental groups of arginine content by 0.45-0.70%, histidine by 0.75-1.60%. The content of leucine, isoleucine, valine, threonine, and phenylalanine increased in the liver of broilers of the III-IV experimental groups by 0.11-0.96%, 0.1-0.6%, 0.10-0.13%, 0.13-0.47%, 0.23-0.53% compared to the control group. The content of linoleic acid in the liver samples of broilers of the I-IV experimental groups increased by 1.80-36.4%, the content of linolenic acid in the liver of experimental chickens of the III-IV experimental groups increased by 0.1-0.2%, and oleic acid – by 0.6-3.3%, respectively. A sharp increase in the content of AST and ALT in the blood of broiler chickens of the experimental groups was not observed, although there is a dose-dependent increase in the activity of these enzymes, which indicates an increase in liver function against the background of the action of ultrafine silicon dioxide.

Published: October 2021

Abstract
The article deals with the regulation of the number of ixodid ticks in the Non-Chernozem zone using mathematical modeling of ixodid ticks that live in the Kaluga region of the Russian Federation. Statistical data is taken for the period of the decade of the research. In the Kaluga Region, two species of ixodid ticks are presented, which are Ixodes ricinus (European forest) and Dermacentor reticulatus (pasture), both demonstrating two regular peaks of their activity in spring and autumn. Analytical and calculated mathematical models of the population of ixodid ticks are obtained based on the composition of three or four factors, including: average monthly air temperature per year, average monthly relative humidity per year, average atmospheric pressure per year. The analysis of the results shows that it makes sense to take into account the composition of the first three factors, excluding cloud cover, as long as the cloud value is minimal is minimal in the Kaluga Region and thus cannot affect the results of the mathematical calculations. There are theories which are based on the hypothesis that both the temperature and humidity have an effect on the size of the ixodid ticks’ population. The obtained models presented in the article prove strong influence of these parameters, but moreover accents the monthly average atmospheric pressure having the greatest influence on the parasites’ population.
