Breeding institutions of Russia and their contribution to improving the apple tree assortment

The requirements for apple cultivars are constantly increasing due to the improvement of their cultivation techniques. Even cultivars, which satisfied consumers 20-30 years ago, now do not meet due to the changed requirements. One of the main reasons for this lag of breeders is the duration of the juvenile period in hybrid apple seedlings. According to our data, it takes 27 years to create one cultivar (from hybridization to inclusion of the cultivar in the State Register of Breeding Achievements). The task is to reduce this period to at least 20 years. This reduction depends on the breeders. The final assessment of the apple cultivar largely depends on the State Commission of the Russian Federation for Testing and Evaluation of Cultivars. Below is information on the number of apple cultivars created in large Russian breeding institutions. 57 apple cultivars have been created and zoned in the Russian Research Institute of Fruit Crop Breeding, of which 4 cultivars have already been zoned in 4 regions, 4 apple cultivars are zoned in 3 regions, 10 cultivars are zoned in 2 regions, the remaining cultivars are zoned in one region so far. FSBSI FSC named after I. V. Michurin (former CSL named after I. V. Michurin and Russian Research Institute of Horticulture named after I. V. Michurin). 37 apple cultivars were created and zoned. Of particular interest, in our opinion, are such new cultivars as Academic Kazakov, Blagovest, Bylina, Vishnevaya, Vympel, Pamyat Nesterova, Krasnoye Rannye, Munster, Flagman and Fregat. FSBSI FSC of Horticulture (Birulyovo). 18 apple cultivars have been created and zoned. All of them are zoned in the Central Region of Russia. North Caucasian FSSC of Horticulture, Viticulture, Winemaking. 34 apple cultivars have been created and zoned, of which 5 cultivars are already cultivated in two regions. Crimea. Nikitsky Botanical Garden. Scientific Center (Crimean Experimental Gardening Station). 14 apple cultivars have been developed. FSBSI Ural Federal Agrarian Research Center of the Ural Branch of RAS. 37 apple cultivars have been developed. In this article, the authors tried to show the tremendous work that apple breeders are doing in different regions of Russia.

The yields of industrial cultivars of primocane raspberry in the Central region of Russia

Industrial raspberry plantations in Russia occupy just over 10 % of all plantings and do not fully meet the needs of the population and the berry processing industry. One of the ways to increase the production efficiency of this crop is the use of high-yielding cultivars for planting new plantations. The aim of the researches was to evaluate the industrial assortment of primocane raspberry type in the conditions of the Central region of the Russian Federation in terms of productivity components and to isolate the most productive ones of them. The work was carried out in 2019-2022 on the basis of the genetic collection of berry crops of the Kokino base station of the FSBSI FRC of Horticulture. 8 cultivars of the primocane raspberry type of domestic selection, included in the register of breeding achievements and meeting the requirements for the industrial cultivar: Atlant, Zhar-ptista, Caramel’ka, Medvezhonok, Pingvin, Podarok Kashiny, Poklon Kazakovy, Salyut served as researches objects. It was established that the largest fruits were formed by the cultivars Salyut (4.6 g), Poklon Kazakovy (4.8 g), Medvezhonok (5.0 g), Podarok Kashiny (5.1 g). The multi-fruited cultivars Medvezhonok, Zhar-ptista and Podarok Kashiny were among the best in terms of stem loading by generative organs (194-216 pcs.). The cultivars Zhar-ptista, Poklon Kazakovy, Atlant, Salyute, Medvezhonok and Podarok Kashiny were distinguished by high yields (15.0-20.0 t/ha). The ripening degree of their harvest on average over the years of researches was 75.4-100 %.

The results and perspectives for breeding of the green manure narrow-leafed lupine varieties for the productivity and morph-and-biological characters

The narrow-leafed lupine (Lupinus angustifolius L.) has long been used as a green manure crop. Alkaloid content which is incompatible with forage varieties is a desirable trait for green manure ones. Alkaloids presented in plowed biomass of the green manure lupine have disinfected action for soil resulted in the lower infection of the next crops. The undemanding nature of green manure lupine to growing conditions consists of several features: it is an active nitrogen accumulator and provides 70 % of nitrogen for own needs, and its deeply penetrated root system allows make up the deficit of nutritional substances in arable layer with use of sub-soil horizons. The aim of the study was to reveal perspective narrow-leafed lupine’s green manure varieties and breeding lines for grain and green mass yield, for length of the vegetation season, alkaloid content and other morphological and biological characters. The tests have been done under Bryansk region’s conditions (the South-West zone of the Central region of Russia) on soddy-podzolic loamy cultivated soils with the moderate fertility level. The objects of the research were seven green manure varieties and breeding lines of the narrow-leafed lupine which have been tested in competition tests of 2021-2022. The breeding line Siderat 265-19 stand out for grain (2.62 t/ha), green mass (31.9 t/ha) yield and for early maturing (84 days). Alkaloid content in its seeds made 1.003 %, the standard level. The article presents the results of structural analyses for morphological peculiarities and productivity elements of new green manure hybrid lines (the standard variety – Tshutchinskiy).). The No. 1764 (Siderat 46 x Kormovoy 344) had the best index for plant height. The No. 1749 (Siderat 46 x Bryanskiy siderat) picked out for grain productivity. The seed weight per a plant was 14.3 g and the pod’s seedingwas 5.2 seeds.

The Alba variety is characterized by increased drought resistance. Designed for lawn and pasture use. In the conditions of the Central Chernozem region, the yield of green mass is 27.3–34.5 t/ha, seeds — depending on the year of use of the herbage, 412–194 kg/ha. When lawn varieties are used, the density of shoots in the herbage of the second year of life can reach 76.0 thousand pcs/m2. In conditions of sufficient moisture, with the observance of lawn care technology, a high density of shoots can be maintained for 6 years. The varieties are resistant to disease.

Идентификация: проблемы, тенденции, методические аспекты

For a commercial enterprise, the identification process as an element of the quality and safety assurance system is very important, as well as for consumers who come to a trading organization and choose the right and safe high quality product. Development of methodological aspects of its implementation is relevant. The methods of the process and system approaches used in the research process made it possible to build a logical chain, where identification, as a common denominator between quality and safety, is the dominant link in the process of selling goods at an enterprise, which is ensured by state regulation of system requirements and its components. A unified methodology for all trade enterprises has been developed on the basis of identifying requirements for the identification process and comparing it with the requirements for quality, safety and with the trade technological process. This methodology for the identification process was developed for the first time, which ensures the novelty and significance of the study. The approach to the formation of the methodology was based on the research of various scientists, who partially touched upon the problems of this development, the legal aspects of the problem in general and the reasons for the appearance of negative results of identification, which in turn causes scientific novelty, reflected in the improvement of the methodological approach to solving the problems of trade enterprises associated with ensuring the quality and safety of goods at the stages of acceptance and display. Ultimately, the developed methodology contributes not only to improving the quality of retail trade services at the regional level, but also allows local trade organizations to reach the level retailers from central regions of Russia, especially in the context of change management.

Adaptation of the Method of Analytical Control of the Content of α-Amylase in Triticale Grain

Triticale grain crop is promising for cultivation in various regions of central Russia. Stable yield, high resistance to adverse conditions, allow us to consider this cereal plant as a reliable source of food production. The purpose of this study was to quantify the content of active α-amylase in triticale grain to provide a forecast of agrotechnical measures. The analysis of the quantitative content of α-amylase was carried out on a laboratory spectrofluorimeter using standard bioassays conducted on the basis of a set of reagents for determining the activity of α-amylase in blood serum and urine; the conversion factor for calculating enzyme activity was calculated using a multiparametric calibrator of biochemical analyzers. To improve the methodology for the determination of α-amylase in real samples of plant raw materials, flour of winter triticale varieties grown in the field was used. Based on the results of measuring the activity of α-amylase in triticale grain, a comparative assessment of the enzyme content in the flour of grain crops of 2020 and 2021 was carried out; the dependence of pre-harvest seed germination on the content of α-amylase in grain of various varieties, lines and hybrids was shown. Based on the data obtained on the content of α-amylase in triticale grain, a comparative assessment of the characteristics of pre-harvest seed germination was carried out. The indicator of the quantitative content of α-amylase can be recommended for use in the diagnosis of pre-harvest germination of grain, as well as in breeding work when creating new varieties of grain crops.

Роль установок на авторитаризм и социальное доверие в проявлениях гражданской и онлайн-активности

<p style="text-align: justify;">Attitudes towards authoritarianism, social dominance, social competition and social trust are important regulators of social behavior. Therefore, correlating attitudes with commitment to various forms of activity is an important step towards understanding and specifying their role in behavior. The purpose of the study is to identify the role of attitudes towards authoritarianism and social trust in the manifestations of civic and on-line activity of Russian youth. Participants. The study involved young people aged 17-35 years (average age M=21.8; SD=6.2) in the number of 442 people (men - 33.5%, women - 66.5%). The sample is representative of the provincial regions of central Russia of economically different strata. Methods. The forms of social activity were measured using direct scaling, the types of activity were determined based on factor analysis. To determine the settings, the J. Dakkit’s scale was used in D.S. Grigoriev's adaptation. Indicators of trust are determined using the Scale of interpersonal trust of J. Rotter in the adaptation of I.Y. Leonova, I.N. Leonova. Correlations have been established between indicators of right-wing authoritarianism, institutional trust with commitment to civic (positive) and Internet network (negative) activity; belief in a competitive world — with a commitment to civic (positive) and protest (negative) activity. As a result of structural modeling, the hypothesis about the direct effect (directed connection) of right-wing authoritarianism and belief in a competitive world on commitment to civic and Internet network activity is confirmed. The role of different attitudes in adherence to certain types of activity varies. Their isolated contribution to activity can reach 16-19%, together with age, religiosity and trust - 19-26% of variations. Trust plays the role of a mediator of a direct connection between attitudes and activity, and at the same time, right-wing authoritarianism also plays the role of a mediator of a direct causal connection between age, subjective religiosity and civic and Internet network activity.</p>

Погребальный звон в центральной части России и в Сибири: преемственность и различия

The traditional Orthodox funeral knells in Siberia are an understudied topic requiring thorough investigation. After the Siberians had gained a rich cultural and spiritual experience of the Russian Orthodoxy, they developed it in accordance with local traditions. First of all, the Siberian bishops, who often had liturgical practice in central Russia, were the bearers of the experience. Before coming to Siberia, funeral knells evolved from single strikes in a special bell to change ringing in all the bells followed by a chord, and their two-part form was developed. A rhythmic pattern of funeral knells for the laity, priests and bishops had its own features. The performance of funeral knells for the Siberians could have a status of a posthumous award at the end of a saintly life; one could be also disappointed of the award in case of a formal attitude to the Church. The resettlers from the Little Russia had a special influence on the performance of funeral knells in Siberia in the early 20th century by introducing their own customs in resettlement villages. One of them was the ringing “for the soul”, unknown in Siberia, which was performed immediately after the death of a layman. The funeral knells for the laity were officially permitted in Siberia in 1911, however people had been used them even before that time in some regions of central Russia. Funeral knells fit into the general palette of Orthodox church bell ringing, acting, at the same time, as a signal, an art and a mass medium. The liturgical instructions survived to our days are fragmentary. The attitude to funeral knells shall be rethought in the modern liturgical practice.

Prvu glad u Ukrajini organizovao je Komunistički režim Rusije 1921-1923: Na 100. godišnjicu žrtava tragedije

The article presents a comprehensive analysis of the Ukrainian famine of 1921-1923, challenging the widely held view that it was a tragic consequence of the civil war, as claimed by Lenin. Instead, the authors argue that the famine was a deliberate result of the Russian Bolsheviks' establishment of a social system reminiscent of feudal Russia. Drawing on the insights of Russian philosopher A. Zinoviev in his seminal work "Communism as Reality," the authors shed light on the underlying causes and motivations behind this man-made disaster. During the brutal war of aggression, the Moscow Bolshevik regime employed various means of mass physical, political, and economic terror to suppress the national liberation movement of the Ukrainian people. One of the most insidious tactics was the imposition of a food dictatorship and the orchestration of the famine itself between 1921 and 1923. This deliberate policy was designed to crush any resistance and consolidate Bolshevik rule over Ukrainian lands. The famine served a dual purpose for the Moscow regime. On the one hand, it ensured a steady supply of vital resources such as food, coal, and metals from Ukraine to sustain the famine-stricken central regions of Russia, the North Caucasus, and Crimea. On the other hand, it enabled the Bolsheviks to establish their power on Ukrainian soil by subjugating and exploiting the population through the terror of famine. The consequences of this policy were catastrophic and far-reaching. The Ukrainian famine resulted in the destruction of the country's most productive agricultural resources, severely impairing the country's ability to feed its own population. In addition, a significant number of children, the future of the Ukrainian nation, died of starvation. Entire villages were devastated, and the subsequent influx of people from the Russian territories changed the ethnic composition of the affected regions, exacerbating the process of Russification. This demographic transformation further eroded Ukrainian cultural distinctiveness, including its scientific, educational, literary, and artistic sectors. The loss of cultural heritage and the erosion of national identity created long-lasting socio-psychological problems that continue to hinder the revival of Ukrainian statehood and its progress toward integration into the European community. The authors contend that the threat to the preservation of the Ukrainian nation and the restoration of an independent, united, and democratic Ukrainian state extends beyond the immediate Russian aggression. These acts of aggression include support for Transnistria, the wars with Chechnya and Georgia, the annexation of Crimea, the conflict in the Donbass, and the full-scale invasion of Ukraine in 2022. The authors argue that severely punishing Russia for its actions is essential to preventing the recurrence of such atrocities in the future. The responsibility to confront the aggressor does not lie with Ukraine alone; it requires the collective efforts of the international community. The article calls for a united front among nations and international organizations to hold Russia and other perpetrators accountable for their actions. It emphasizes the importance of implementing robust legal mechanisms, such as international tribunals, to punish those responsible for crimes against humanity, ensuring that they face the full force of justice. Moreover, the call for a united front extends beyond Russia, recognizing that crimes against humanity are not confined to a single nation or region. It highlights the necessity of addressing and preventing such atrocities on a global scale, emphasizing the shared responsibility of all nations to protect human rights and uphold international law.

On the issue of creating the optimal last stage of powerful steam turbines of nuclear power plants

THE PURPOSE. To estimate the most effective length of the working blade of the last stage of a powerful wet-steam turbine in terms of obtaining its maximum efficiency and to optimize the parameters of this stage in the design mode. For this stage, perform multi-mode optimization to select the main characteristics of the stage operating with maximum efficiency according to a given model daily load schedule.METHODS. When solving this problem, the method of calculating the axisymmetric flow of steam in the flow part of the turbine stage as an inviscid single-phase working fluid relative to a stationary guide device and rotating with an angular velocity ω of the impeller used, and the losses energy calculated according to the axisymmetric method of the MPEI.RESULTS. The article describes the relevance of the topic, discusses the features of the use of the author's software in solving the tasks. The characteristics of the stages with different lengths of the working blades presented and the results of their calculation in the nominal mode are given. A model daily schedule selected for a nuclear power plant turbine operating in the central region of Russia. The results of calculations of variable modes of the last stage of the turbine operating according to this daily schedule presented.CONCLUSION. The choice of the maximum length of the working blade is limited not only by its strength characteristics, but also by the increase in wave losses in the gratings due to an increase in the optimal available heat drop, or rather the associated increase in supersonic speeds near the meridional contours. So for a high-speed turbine To-1200-6,8/50 the maximum efficiency of the last stage is achieved at a length of 1400 mm, both when the turbine is configured with both three two-flow LPC and four. Selection of the main characteristics of these stages, such as the available heat drop, the degree of reactivity, etc. it should be made taking into account the variable operating modes of the turbine on the basis of the forecast of daily schedules of loads of turbine units. When using a typical daily load schedule, the average internal relative efficiency in the range of operating modes according to this schedule is higher by 0.6 % when choosing a 10% increased available heat drop compared to the optimal one in the design mode.

The article presents the results of the selection work of the laboratory of breeding and seed production of table root crops of the Federal Scientific Vegetable Center for the culture of Chinese radish (loba). From the collection material (a total of 23 samples were studied), a promising material was selected under the number No. 600 for a complex of economically valuable features. The purpose of the research is to create a variety of Chinese radish – loba for open and protected ground. Based on this goal, the objectives of the research included: to evaluate a promising variety of loba in a nursery of competitive variety testing in open and protected ground conditions, to assess alignment according to the main morphobiological parameters, as well as to assess the safety and resistance to diseases during storage.Results. As a result of repeated individual and family selection in the direction of productivity, resistance to premature stem formation and diseases of vegetation and storage, as well as improvement of taste qualities, a new variety of Chinese radish Serdtse Podmoskovya was bred. The new variety belongs to the pink-red rounded varietal type. The root crop is flat-rounded, large in size. The flesh is white, juicy, with a slightly spicy taste. The variety is medium-ripened, the growing season is 65-75 days, suitable for use in early summer, autumn and winter, resistant to longterm storage (95-96% preservation) and low light. The yield of the variety in protected ground is 2.7 kg/m2, marketability – 88.7%, root crop weight – 533 g; dry matter content – 6.26%, sugars – 2.56%, ascorbic acid – 19.36 mg%. The variety on this background was distinguished by the absence of flowering and diseased plants. The yield in the open ground was 31.2 t/ha (3.12 kg/m2), marketability – 81.2%, root crop weight – 281 g. The variety under these conditions was characterized by a higher content of dry matter –11.0%, sugars – 3.2% and ascorbic acid – 20.13 mg%; a small percentage of flowering (9.4%) and affected plants (6.3%) was noted. For this variety, a technology has been developed for obtaining original and elite seeds according to a one-year development cycle in the conditions of the Central region ща Russia.

Herbarium of the Institute for Biological Problems of Cryolithozone (SASY): Plant type specimens

This article presents an annotated list of plant type specimens stored in the Herbarium of the IBPC SB RAS (SASY), which is one of the largest in northeast Russia. The Herbarium fund is represented by five departments (vascular plants, mosses, lichens, aphylophore fungi, and algae), where about 95000 herbarium samples are stored exluding algae tests. The Herbarium has a collection of plants from Western and Eastern Siberia, the Far East, and some central regions of Russia. The exchange fund contains more than 3000 species of plants. Typical samples stored in Herbaria are of a particular value. In total, 14 species and 2 subspecies of liverworts, mosses, and vascular plants from 11 families were isolated from the main collection of the SASY Herbarium, which are represented by 14 types, 16 isotypes, 14 paratypes, and 5 epitypes (Frullania ignatovii Sofronova, Mamontov et Potemkin, Barbula jacutica Ignatova, Grimmia jacutica Ignatova, Bednarek-Ochyra, Afonina, J.

Physiological status and genetic abnormalities of imported cattle in extreme Arctic zone conditions

Blood in the body of animals performs various functions aimed at maintaining its vital activity. The main indicators of blood make it possible to judge the state of the body, since the processes associated with the growth, development of productivity. According to the researchers, the composition of peripheral blood is greatly influenced by the age of the animal, sex, physiological state, feeding and maintenance conditions. The current intensification of livestock development contributes to the strengthening of a number of adverse environmental factors that may lead to insufficient animal adaptation mechanisms. The most significant stress factor affecting the animal body is the seasonal factor. It was revealed that the most stressogenic for productive livestock are the winter and spring seasons of the year. At the same time, local (indigenous) animal breeds are well resistant to extreme environmental influences, but, as a rule, they have low productivity. Therefore, there has recently been a trend towards a qualitative improvement in livestock production in these areas by importing highly productive animals into them in order to acclimate them and use them to create new breeds based on crossing with natives. Yakut animals in the world gene pool of cattle in terms of distribution range occupy the northernmost part and are known for good adaptation abilities to harsh conditions of detention, resistance to many diseases. In world practice, there are no analogues to the Republic of Sakha (Yakutia) in animal husbandry as a self-functioning system in the Arctic. The history of the development of cattle breeding shows that due to extreme natural and climatic conditions in Yakutia, a special approach to breeding work is needed. This is primarily due to the prolonged winter stall period. The basis of rational zoning accurate knowledge of the history of their development and formation of adaptive capabilities should be established. In this regard, the study of adaptive features, morphophysiological systems that cause increased resistance of animals to adverse environmental factors, in particular, to low temperatures, is of great theoretical and practical importance. Currently, in the republic, many farms are engaged in breeding specialized breeds of cattle of the dairy and meat direction. At the same time, animals are imported not only from the central regions of Russia, but even from foreign countries. In recent years, 3683 goals have been brought to the territory of Yakutia. livestock, including dairy – 2377 heads (64.5%). Among the introduced cattle there are completely new breeds for cattle breeding in the republic - such as Hereford, Kalmyk, red steppe, red-variegated, black-variegated and Sychov.

The results of the field accounting of medicinal plants in the forest and forest-steppe zones of Central Russia

To assess the potential of the raw material base of medicinal plants and search for new plant sources of biologically active substances, it is necessary to monitor and record the biological diversity of plants, their number and abundance in natural plant communities. Plants are counted by the transect method. In the course of field research in 2022, the biodiversity, abundance, and abundance of medicinal plants in three regions of Central Russia were assessed. In the Lipetsk Region (the lower reaches of the Chichera River, the valley of the Sukhaya Lubna River), the most notable species of the Ranunculaceae families were identified: Adonis vernalis L. (spring adonis); Rosaceae: Agrimonia eupatoria L. (common agrimony); Filipendula vulgaris Moench (six-petalled meadowsweet). In the Samara region (floodplain of the Sok River) - Rosaceae: Sanguisorba officinalis L. (burnet officinalis); Filipendula vulgaris Moench; Ranunculaceae: Adonis vernalis L. In the Moscow, Ryazan region (Meshchera) species of families - Rosaceae: Potentilla argentea L. (silver cinquefoil) (Rosaceae), Fragaria vesca L. (wild strawberry), Potentilla erecta L. (upright cinquefoil), Comarum palustre L. (marsh cinquefoil); Onagraceae: Chamaenerion angustifolium (L.) Scop. (fireweed narrow-leaved); Asteraceae: Helichrysum arenarium (L.)

(horsetail); Lamiaceae: Stachys palustris L. (marsh weed); Primulaceae: Lysimachia vulgaris L. (common loosestrife). A total of 65 species of medicinal plants have been identified. Species with a noticeable abundance are characterized as a source of a certain group of chemical compounds. To assess the potential of the raw material base of medicinal plants and to search for new plant sources of biologically active substances, it is necessary to monitor and account for the biological diversity of plants, their size and abundance in natural plant communities. Accounting of plants is carried out by the transect method. In the course of field research 2022 year, the biodiversity, size and abundance of medicinal plants in three regions of Central Russia were evaluated. In the Lipetsk region (the lower reaches of the Chicher River, the valley of the Sukhaya Lubna River), the most notable species were identified - Ranunculaceae: Adonis vernalis L.; Rosaceae: Agrimonia eupatoria L.; Filipendula vulgaris Moench. In the Samara region (floodplain of the Sok river) - Rosaceae: Sanguisorba officinalis L.; Filipendula vulgaris Moench; Ranunculaceae: Adonis vernalis L.

Scop.; Asteraceae: Helichrysum arenarium (L.) Moench.; Caprifoliaceae: Valeriana officinalis L.; Hypericaceae: Hypericum maculatum L.; Equisetaceae: Equisetum arvense L.; Lamiaceae: Stachys palustris L.; Primulaceae: Lysimachia vulgaris L. A total of 65 species of medicinal plants have been identified. Species with a noticeable number are characterized as a source of a certain group of chemical compounds.

Reputation core of Russian authorities: the case of the regional level of executive power

The importance of studying the reputation of authorities is connected, on the one hand, with the formation of a consolidated system of political power and, on the other hand, with the highly social orientation of the category of the ‘reputation of authorities’, reflecting the value-based attitude of citizens towards them. The article presents the results of research aimed at the analysis of the reputation of Russian authorities, with a special focus on the regional branch of executive power. The paper examines the reputation of Russian authorities of different levels and branches using the example of regional executive bodies. The author determines the structure and features of the reputation core of the conceptual category ‘Russia’s authorities’ understood both as federal and municipal authorities of the Russian Federation as a whole. The article also offers a comparison of the reputation core of regional executive authorities with that of ‘Russia’s authorities’ in general. The methods used in this research are expert assessment and population surveys conducted in six regions of Central Russia. The study has revealed the main characteristics constituting the reputation core of executive authorities and described their specificity in different regions. Based on the results of the theoretical and empirical analyses, the author proposes a novel approach to defining the structure of the reputation core characteristic of the federal and regional executive authorities. The reputation core is a multi-component conceptual construct dominated by several integrating characteristics such as honesty, responsibility, justice, concern for and protection of citizens. No differences in the structure of the reputation core of the federal and regional executive authorities have been identified. However, the degree to which these characteristics manifest themselves varies. The reputation of regional authorities is assessed based on a system of values, expectations and the results of their work with the federal centre, citizens’ experience of communication with regional authorities and the assessment of their activity. The reputation of the regional executive authorities is characterised by lesser stability of the conceptual characteristics of the near periphery and greater dynamism of the outer conceptual boundaries, especially in specific regions.

Transport infrastructure development issues affecting the socio-economic situation in Arctic

The object of the research in this article is the transport infrastructure of the regions that are part of the Arctic zone of the Russian Federation. The authors aim to study the main socioeconomic problems that exist in the region due to the underdevelopment of transport infrastructure, as well as ways to solve them. To fulfil their research objectives, the authors used a comparative analysis method, a correlation analysis method, and a legal analysis. The study identified the specifics of the construction of transport infrastructure in the far north regions. The length of the road and rail network in the Arctic has been analysed compared with the regions of Central Russia, and the factors that limit the development of transport infrastructure have been identified. The strong dependence of freight traffic volumes on population size was revealed using the example of the Murmansk Oblast, and the main problems affecting the demographic situation in the region were identified. The problem of low passenger flow in air transportation was considered. The authors suggested the following ways of solving the problems: increasing the number of contracts PPP in their classic form, reducing the number of concession agreements, creating a transport system project based on the example of the US Interstate Highway System in the Russian Arctic, drafting a unified transport budget for all territories that make up the Arctic zone, creating a single executive authority for the Arctic zone to distribute the budget evenly.

It is shown that in the agricultural sector alternative agriculture has been formed due to activation of biological processes. The directions of digital transformation of biological agriculture in the south-west of the Central region of the country are studied in the paper. It is established that smart farming technologies are currently being used in the Bryansk region; they are based on the application of geoinformation and satellite systems, as well as equipment monitoring systems. Digital solutions are being introduced in animal husbandry. The areas and specifics of consulting services to economic entities in order to develop biological agriculture are substantiated.

Protozoal infections of young turkeys in the conditions of industrial farms

The article presents the results of monitoring of parasitic protozoa of young turkeys in industrial-type farms of the Central region of Russia. Fecal samples, scrapings from the floor and passages, and the contents of the gastrointestinal tract during slaughter were systematically examined in birds of different ages. The age and seasonal dynamics of their infection with eimeria, as well as contamination of environmental objects by protozoan oocysts, were established. At the same time, the following species were identified in turkeys: Eimeria meleagrimitis (80%), E. meleagridis (15%), E. adenoids (5%). The prevalence in males of 35-49 days old, and in females of 35-49-63 days old was the maximum and amounted to 30–45 and 5–30%, respectively. The obtained results should be used in the organization of therapeutic and preventive measures against parasitic protozoa of young turkeys.

Mycotoxin contamination of fresh berries and fruits marketed in the central region of Russia

New emerging strains of toxigenic molds in agricultural areas and insufficient data on levels of their toxic metabolites occurring in domestic horticultural fruits and berries require risk assessment of MT contamination for this plant group of mass consumer products. This study concentrated on samples of fresh fruits and berries sold on the consumer market (185 samples, including 127 intact and 58 with signs of deformation and molding). We applied our own developed technique for quantification of mycotoxins based on HPLC-MS/MS. In this study, we were the first in the RF to examine contamination of garden strawberries, raspberries, currants, huck-leberries, blueberries, gooseberries, dogwood, plums, blackthorn, apples, pears) with 27 MT including poorly studied emergent MT (EMT), produced by Aspergillus, Penicillium, Fusarium and Alternaria. Strawberries, gooseberries, black currants and raspberries turned out to be the most contaminated with MT; red currants, apples and pears were less contaminated. The greatest variety of MT and EMT species was found in strawberries (23 MT), gooseberries (8 MT), black currants (7 MT) and raspberries (6 MT). Among the regulated MT, fumonisins B1 and B2, deoxynivalenol, zearalenone, T-2 toxin, ochratoxin A and aflatoxin B1 were detected in intact strawberries; patulin, in raspberries; deoxynivalenol and zearalenone, in black currant. As for damaged and moldy berries and fruits, the list of detectable toxins was expanded, primarily due to the detection of several types of unregulated EMTs. EMT tenuazonic acid was mainly detected in moldy berries; its levels increased manifold in almost all species, except for strawberries in which penicillic acid prevailed. These new data on MT contamination in fruits and berries indicate the necessity to perform in-depth hygienic assessment of such products sold on the Russian market to identify MT, EMT and their producers. The obtained results will be used to identify hazards at the first stage in risk assessment with its focus on MT and EMT contamination of fresh fruits and berries.
