This article deals with the issue of drug usage, narcotics, and psychotropic substances. The Sinar Djati Kemiling Lampung Foundation is one of the institutions where the drug victim service and rehabilitation program is implemented which uses alternative treatment methods in the form of physical, mental, religious, and skills. Sufism therapy is used in overcoming anxiety in clients with drug abuse. It is about how to implement fasting therapy to overcome the anxiety of drug abuse clients, what are the effects of the therapy, and the barriers to it. This research uses a descriptive qualitative method. Data collection methods used are observation, interviews, and documentation. The source person in a study is determined with the use of snowball sampling technique. The fasting therapy is carried out systematically and regularly to overcome anxiety. Apart from the fasting therapy, there are also several activities carried out by clients such as praying, reading the Koran, and praying. Second effect of fasting therapy is to overcome the anxiety of drug clients, it can be said to have succeeded in reducing the level of anxiety in drug clients because the results of interviews with informants were proven to have reduced anxiety among the drug clients. Third, obstacles experienced by researchers when implementing fasting therapy to overcome anxiety i.e., clients find it difficult to manage fasting such as sahur and breaking the fast.

Authors: Fedorov Yuri A. , Trubnik Roman G. , Garkusha Dmitry N. , Dotsenko Irina V.
Published: April 2024

The results of field studies of bottom sediments (peloids) of the hypersaline lakes Belyamin, Baskunchak, Elton and flows into Elton the small Smorogda River are presented. The number of sulfite-reducing clostridia (SRC) in bottom sediments was determined and the perfringens titer was calculated. Based on the perfringens titer, the sanitary and microbiological state of bottom sediments was assessed for the possibility of their use for balneological procedures. Based on the perfringens titer, the possibility of using bottom sediments for balneological procedures was assessed. Research has shown that in samples of individual layers of bottom sediments of Lake Baskunchak and the mouth of the Smorogda River, which flows into Lake Elton, the number of vegetative cells of sulfite-reducing clostridia slightly exceeds the standard values for peloids. The ingress of sewage into the peloids of Lake Baskunchak may be due to the settlements of Verkhny Baskunchak, Sredniy Baskunchak and Nizhny Baskunchak located near the lake. Participation of sulfite-reducing clostridia, along with sulfate-reducing bacteria, in the generation of methane and hydrogen sulfide was noted. The possibility of using data on methane content and the amount of SRC to assess the ecological state of peloids is shown.

Published: April 2024

The northern part of the Agrakhan Bay, which used to play a peculiar role of a receiving reservoir for migratory and semi-migratory fish migrating to spawn and wintering, and served as a kind of nursery for the development of larvae of their young, rolling here from spawning-growing reservoirs and the lower reaches of the Terek, in recent years, as a result of a critical decrease in river flow and a drop in the level of the Caspian. It has ceased to perform its main functions to increase fish stocks in the Terek-Caspian fisheries area. Among semi-migratory fish, the walleye is of particularly important fishery importance, as the largest and most valuable representative of the Percidae family in commercial and food relations. It was found that the structure of the walleye population in the northern part of the Agrakhan Bay in the last 2018-2021 turned out to be the most susceptible to unaccounted withdrawal, and its number is in a depressed state. It was revealed that the current level of reproduction of walleye in the bay turned out to be relatively lower as a result of intensive overgrowth and weak water availability. Histological examination of the gonads showed that the ovaries of walleye in the IV stage of maturity are for five months, from the end of October to April. It is established that the growth rate at different stages of development depends on environmental factors (hydro-hydrochemical and temperature regime of reservoirs, regime, salt balance, etc.) as well as their food supply.

Published: April 2024

Pasture digression is one of the main factors of degradation and desertification of territories in the South of Russia. The impact of unsustainable grazing of agricultural animals on plant and soil cover has significant negative consequences, as a result of which the modern vegetation of the semi-desert of the Northern Caspian region has changed greatly over the decades and has taken on unfavorable dynamics. The object of the study was the soils of the Astrakhan region, subject to various stages of pasture digression. Phytoindication was carried out according to the indicators of germination and intensity of initial growth using a traditional test culture (Raphanus sativus L.). As a result of the study, no dependence was established between the indicators of germination and intensity of initial growth of radish on the stages of pasture digression. Soil phytotoxicity depended on soil properties, such as humus content, mobile phosphorus, soil solution reaction, and soil density.

Published: April 2024

The influence of geothermal waters located on the territory of the city of Makhachkala (Republic of Dagestan), in the composition of solid cultivation media, on the cultural and morphological features of genus Saccharomyces yeast was studied. Changes in cell properties and the formation of specific parameters of giant yeast colonies S. cerevisiae Y-503, S. cerevisiae DAW-3a, S. oviformis M-12x have been established. For YPD and PD media, as a result of a series of experiments, optimal options were selected containing geothermal and distilled water in a ratio of 1:1 (well No. 36) and 2:1 (well No. 26). It was shown that the YPD medium was optimal for yeast growth, while in the population of the tetraploid Y-503 strain, the average cell size was slightly larger than cell strain M-12x and significantly exceeded the DAW-3a values. Installed that the use of diluted water from well No. 36 in the cultivation medium is most effective and leads to accelerated growth of yeast colonies. In the variant geothermal / distilled water, this indicator exceeded the control by 1.3 (Y-503, M-12x) times; in the variant with geothermal water without dilution - by 1.6 (Y-503) and 1.4 (M-12x) times. The cells of the S. cerevisiae Y-503 strain, regardless of the medium used, are characterized by the presence of various forms, including elongated ones; DAW-3a - exceptionally rounded; S. oviformis M-12x - rounded and oval shapes. A comparative analysis of the parameters of the colonies showed that all variants are characterized by a rounded shape, a radially striated surface; flat, with a convex center profile; light beige color and pasty, spreadable texture. As a result of our research, a modified nutrient medium PD has been developed - an agar for growing yeast, containing geothermal water from well No. 36 of the Makhachkala field as an additional source of mineral and organic compounds. The proposed composition of the medium is of interest for its further use in microbiological studies.
Collapse of the Attached Cavity at Low Froude Numbers after a Separation Impact of a Floating Elliptical Cylinder
Authors: Norkin Mikhail V.
Published: April 2024

The plane problem of the collapse of an attached cavity formed as a result of a separation impact of an elliptical cylinder under the free surface of a heavy fluid is considered. It is assumed that after the impact the cylinder moves horizontally with constant velocity. At small Froude numbers, which correspond to small velocities of the cylinder, the free boundaries of the liquid are slightly perturbed and the process of cavity collapse is mainly reduced to the study of dynamics of breakaway points. The solution to this problem is constructed using asymptotic decompositions on a small parameter, which is the Froude number. In the main asymptotic approximation, the mixed boundary value problem of potential theory with one-sided restrictions on the body surface is formulated. On its basis, the dynamics of detachment points, the shape of a thin cavities, and the reaction of the environment to the body are determined. The results obtained can be used for solving practical problems of marine and ship hydrodynamics.
Continuous Dependence of Solutions to the Linearized Initial-Boundary Value Problem of Transport of Multicomponent Sediments on the Input Data of the Problem
Authors: Sidoryakina Valentina V.
Published: April 2024

We consider a chain of problems linearized on a time grid that describe the processes of transport of multicomponent sediments in relation to coastal marine systems. In the author's previous works, the conditions for the existence and uniqueness of a solution to this class of problems were determined, while simultaneously determining the requirements for the smoothness classes of the input data of the problem. The result of this study is related to obtaining an a priori estimate of the norm for solving the problem depending on the integral esti-mates of the right-hand side, boundary conditions and the norm of the initial condition. The obtained a priori estimates allow us to further carry out computationally stable calculations with respect to small errors in the initial data and to errors that arise during calculations.

Authors: Erusalimskiy Iakov M. , Shkuray Irina A.
Published: April 2024

The article is devoted to the history of mathematical modeling at Rostov State University (RSU), now Southern Federal University (SFU). The authors have been describing it since 1950. As elsewhere in the world, its begin-nings are associated with problems of mechanics. At the Rostov State University, its founders are considered to be I.I. Vorovich and N.N. Moiseev, future academicians of the Russian Academy of Sciences. The flourishing of work on mathematical modeling is associated with the opening of a computer center at the Rostov State University (1958), and then a research institute of mechanics and applied mathematics (1971), where a simulation model of the Sea of Azov was created, for which its developers were awarded the USSR State Prize. The article examines not only the history of mathematical modeling as a scientific direction, but also the history of its formation as an academic subject at the Faculty of Mechanics and Mathematics (now the I.I. Vorovich Institute of Mathematics, Mechanics and Computer Science of the SFedU).
Parameters Estimates on Samples with Contamination
Authors: Yao Keyu
Published: April 2024

Parametric estimates based on contaminated samples are considered in the paper. The paper provides an over-view of algorithms for estimating the mean and the variance for a one-dimensional sample, as well as estimating the mean vector and the covariance matrix for a multidimensional sample. The paper uses the Minimal Covariance Determinant (MCD) algorithm adapted for one-dimensional sample and the MCD algorithm for multidimensional sample. The parameters are estimated on a subsample, the size of which is determined by a given confidence probability. Examples for samples with different levels of contamination are considered. In both examples, the sample was a union of two subsamples. The first subsample, the main one, was generated by normal distribution laws. The second subsample, auxiliary, was generated by different distribution laws. The examples demonstrate the dependence of the estimation accuracy on the confidence level and contamination. The figures illustrate the operation of the MCD algorithm. The main idea of the paper is to show the robustness of the MCD algorithm.

Published: April 2024

For the first time, full-scale measurements of methane and carbon dioxide emissions by the chamber method were carried out in summer for groundwater sources discharged in the valley of the Peshernaya Gulch creek, located in the north-west of Lake Baskunchak. pH values, concentrations of CH4, basic ions, gross Fe and Mn were determined in the water of the sources; concentrations of CH4, H2S, organic matter, Eh and pH values, density and humidity were determined in various layers of bottom sediments (up to 27 cm). A detailed description of the identified groundwater sources was carried out, their primary morphometric and morphological characteristics were measured, as well as the flow rate. It was found that more than 10 ascending karst sources of groundwater are discharged in the Peshchernaya beam, 5 of which were active during the research period and mainly confined to the left screw of the beam. The active sources of the left screw of the beam are characterized by a small flow rate and are sodium chloride brines with a mineralization of 93.9–107.1 g/l. The bottom sediments accumulating in the sinkholes of underground sources are characterized by a neutral acid-base environment and restorative conditions. The concentrations of CH4 and ∑H2S in the sediments of the sources varied, respectively, in the range of 0.08–0.77 µg/g vl.o. and 0.023–2.63 mg/g vl.o. with minimal values for both gases in the lower less reduced layer with a low content of Sorg. The concentration of methane in the water of active sources varied from 26.3 up to 38.4 µl/l and was on average 2 times higher than in the waters of a stream fed by them and an inactive source. The specific methane flux from the water surface of active sources varied in the range of 0.6–1.5 mg/(m2∙h), which is 2 orders of magnitude lower than the specific CO2 flux of 46.4–106.1 mg/(m2∙h). The isotopic composition of carbon (δ13C) CH4 and CO2 measured in gas bubbles rising from the bottom of one of the ascending sources indicates the modern biochemical genesis of these greenhouse gases.

Analiza pokazuje sposoby angażowania się w czytelnika tworzenie gazety, polegające na pisaniu tekstów. Owo zaangażowanie najbardziej widoczne jest w czasopismach lokalnych, które znajdują się najbliżej swoich odbiorców. „Nowe Życie Pabianic” ukazuje się od ponad 21 lat, na łamach tej gazety zdążyły więc rozwinąć się rozmaite formy wypowiedzi czytelników.
Do tradycyjnych należą listy do redakcji i amatorskie formy poetyckie czy prozatorskie. Nowe formy to tzw. „migawki ze słuchawki”, czyli głosy opinii publicznej. Kolejny przejaw współuczestniczenia w przekazywaniu treści to tzw. dziennikarstwo obywatelskie.
Nowe formy wypowiedzi, związane także z rozwojem Internetu, uwidoczniają skłonność do wchodzenia czytelnika w rolę dziennikarza. Dziennikarz kształtujący opinię publiczną zyskuje partnera-czytelnika, przedstawiciela opinii publicznej. Ten swoisty paradoks staje się kolejnym przejawem demokratyzacji mediów i społeczeństwa.
Antropologiczna refleksja nad dziennikarstwem prasowym
Authors: Latocha Sebastian
Published: April 2024

Dziennikarstwo prasowe nie istnieje bez gazety, ale gazeta nie jest całością dziennikarstwa prasowego. Wychodząc z tego punktu widzenia, kwestia prasowych gatunków dziennikarskich nie wydaje się istotna. Genologia nie wychodzi poza świat gazety. Tymczasem, antropologiczna refleksja nad dziennikarstwem prasowym obejmuje namysł nad doświadczeniem, które jest czymś więcej niż ślad, jaki po nim zostaje – artykuł w gazecie. W antropologii mówi się o dwóch sposobach poznawania – emic i etic. W moim artykule rozważam możliwości i ograniczenia wykorzystania tych pojęć w stosunku do dziennikarstwa prasowego, zastępując genologię poszukiwaniem w tekstach przede wszystkim doświadczenia poznającego podmiotu. To doświadczenie osiada w nich pod postacią retorycznego osadu.

Authors: Lukovnikov Egor , D'yachenko Leonid , Smirnov Ivan
Published: April 2024

The issue of considering the dynamic interaction of the railway rolling stock and the structures of bridge structures is especially important when solving the tasks of increasing the speeds of trains on the existing railway lines, as well as when prescribing high-speed mode on designed bridges. Rational accounting of the parameters of dynamic interaction allows you to perform complete and reliable calculations of elements of bridge structures, which in turn has a beneficial effect on predicting the period and nature of the operation of structures and, because of the economic component of projects. The modern solution to the problem of dynamic interaction is reduced to determining the degree of influence of each component of the unified mechanical system of the bridge-travel. Objective: the purpose of this study is to determine the parameters of dynamic interaction through experimental measurements of stresses, accelerations, and displacements of structures of the bridge structure located on the existing railway line with an organized high-speed traffic movement. Methods: experimental measurement using high-frequency voltage sensors, accelerations and movements with subsequent statistical processing and analysis of the results. Results: graphs and tables displaying a change in the measured values of relative deformations, accelerations, and movements over time. Practical importance: The practical significance of this study is to assess the degree of influence of the components of the dynamic interaction of high-speed rolling composition and the bridge structure, which allows you to form a holistic picture of the nature of the process of dynamic interaction.
Analysis of the stress-strain state of nodal joints of high-rise buildings taking into account climatic influences
Authors: Belash Tat'yana , Kuznecov Anatoliy , Volodchenko Dina
Published: April 2024

Purpose: to analyze the design solutions of the junctions of floors with external walls in buildings erected using monolithic technology. To identify defects and damages that occur on facades and overlaps with perforations for thermal pads during construction and operation. To investigate by numerical methods the stress-strain state of the overlap disk at the junction with the outer wall, taking into account temperature influences. Materials and methods: the standard version of the nodal connection of a monolithic building of various storeys is considered. The fragment of the junction joint of the overlap disk with the wall was modeled in the Ansys and SCAD software complexes. The model consisted of an anisotropic material — concrete and reinforcement rods included in it. The behavior of the stress-strain state under various temperature influences was studied. Results: numerically, taking into account geometric parameters and temperature loads, the patterns affecting the nature of changes in the values of normal stresses in the characteristic sections of the perforated plate are revealed and the existing types of design solutions are evaluated. The locations of stress concentration zones and their impact on performance are determined. Practical significance: it is shown that the most dangerous cross-section in perforated discs of overlaps takes place at the key joints. It is determined that vulnerability in such compounds is caused by the influence of alternating cyclic temperatures. Patterns leading to an increase in normal stresses at stress concentration sites have been established. Fundamentally new design solutions have been proposed, protected by utility model patents, which allow to reduce stress values and thereby ensure higher performance in monolithic buildings, including high-rise ones.

Authors: Volkova Elena , Gur'yanov Andrey
Published: April 2024

Objective: the article proposes a method for assessing the efficiency of passenger transport hubs, based on the key principles of operation management. Methods: to achieve the goal of the study, methods of calculating coefficients evaluating compliance with the basic principles of operations management, methods of statistical analysis and data processing, and the method of simulation are used. To carry out the research, materials from scientific papers on the chosen topic, periodicals, as well as Internet resources, including open data from the St. Petersburg Transport Committee, were used. Results: the main scientific result is a method developed by the author to evaluate the efficiency of passenger transport hubs, based on the key principles of operations management. The proposed method takes into account the specifics and characteristics of passenger transport hubs and can be used at any stage of their life cycle, including at the design stage. Unlike the available methods, the proposed methodology allows timely detection and elimination of “bottlenecks” in the planning solutions of a passenger transport hub. Practical significance: as a result of testing the methodology on the example of the Volkovskaya transport interchange hub project, practical recommendations were formed to eliminate bottlenecks and increase the capacity of the facility. The author’s developments can be used in the executive bodies of state power responsible for the development of urban transport infrastructure, and in design organizations in the planning processes for the construction and modernization of passenger transport hubs, as well as in evaluating the effectiveness of their work.

Published: April 2024

Objective: show the prospects of using an innovative type of public urban transport - a digital tram on tires with optical guidance along a strip marked on the road or using magnetic markers along the route, as attractive to passengers, cheaper in the arrangement of lines, as well as requiring less time to build than rail tram for urban transportation, allowing to relieve city roads from traffic jams and improve their ecology. Methods: an analysis and generalization of the operating experience of new digital trams built by the Chinese company CRRC, operated in the cities of China: Zhuzhou, Yibin, Yongxiu, Yancheng and Shanghai, as well as the most advanced designs of the operating rolling stock. Results: the operation of the tire tram revealed a number of problems: after a year of operation, severe rutting appeared on a dedicated lane of the road, speeds and capacity were lower than declared. The construction of new tire tram lines required costs for strengthening the roadway, which was not originally intended by the manufacturer. The possibility of their use in winter climate conditions on roads covered with ice and snow has not been proven. Further testing is required to identify and eliminate emerging deficiencies. Practical significance: despite a number of identified shortcomings, it is advisable to use a digital tire tram for cities with a warm climate, with complex terrain and narrow streets as a medium-capacity vehicle that can improve the mobility and quality of life of citizens, as well as reduce the negative impact on the environment. It is advisable to lay it in new residential areas and industrial zones under construction, as well as to use it for mass transportation of passengers in the event of any major one-time events: major exhibitions, forums, Olympic Games, world football championships, etc.

Wine’s Belated Globalization, 1845 to 2022
Authors: Anderson Kym , Pinilla Vicente
Published: April 2024

This summarizes and updates an article originally published as Anderson and Pinilla (2022).Until the 1970s, wine was produced and consumed almost exclusively in the Mediterranean region and the nearby Levant. Today it is enjoyed in a much broader range of countries. Yet notwithstanding the dramatic recent globalization of this product, the total volume consumed is very similar today to what it was in the 1960s. The apparent inconsistency between these two facts is explained by a huge decline in wine consumption in the most wine-focused countries, the rapid growth in wine production in and exports from New World countries, the gradual move by consumers from other alcoholic beverages to wine in previously beer- or spirits-consuming cultures, and most recently a dramatic rise of East Asia as a wine-importing region.
Unrealistic Optimism and Early Recessions
Authors: Doh Hyun Soo , Pan Jiahao
Published: April 2024

In this paper, we consider an economy, in which consumers exhibit unrealistic optimism, and show that such an economy is more likely to undergo early recessions and underinvestment rather than experiencing bubbles or overinvestment. In this model, each consumer incorrectly believes that a negative aggregate preference shock will hit all other consumers, but not herself. When consumers have such an unrealistic optimism, the output price must fall prematurely before the aggregate shock occurs. The reason is that if the price does not plummet today, all consumers would postpone making purchases by falsely expecting that an arbitrage opportunity will arise in the future when the aggregate shock hits the economy, in which case, the output market cannot clear. We also show that the government has the potential to improve welfare of the economy by providing subsidies, if the government judiciously selects the right timing for intervention.
An Entomopathogenic Nematode, Oscheius tipulae, Exhibiting a Wide Pathogenic Spectrum and Its Application to Control Dipteran Insect Pests

Published: April 2024

An entomopathogenic nematode, Oscheius tipulae, was isolated from a soil sample. The identification of this species was supported by morphological and molecular markers. The nematode isolate exhibited pathogenicity against different target insects including lepidopteran, coleopteran, and dipteran insects. The virulence of this nematode was similar to that of a well-known entomopathogenic nematode, Steinernema carpocapsae, against the same insect targets. A comparative metagenomics analysis of these two nematode species predicted the existence of a combined total of 272 bacterial species in their intestines, of which 51 bacterial species were shared between the two nematode species. In particular, the common gut bacteria included several entomopathogenic bacteria including Xenorhabdus nematophila, which is known as a symbiotic bacterium to S. carpocapsae. The nematode virulence of O. tipulae to insects was enhanced by an addition of dexamethasone but suppressed by an addition of arachidonic acid, suggesting that the immune defenses of the target insects against the nematode infection is mediated by eicosanoids, which would be manipulated by the symbiotic bacteria of the nematode. Unlike S. carpocapsae, O. tipulae showed high virulence against dipteran insects including fruit flies, onion flies, and mosquitoes. O. tipulae showed particularly high control efficacies against the onion maggot, Delia platura, infesting the Welsh onion in the rhizosphere in both pot and field assays.

Published: April 2024

The development of reliable predictive algorithm for house price as the housing market is a stand-out among the most involved regarding valuing the price and continues to fluctuate, is constantly a need for socio-economic advancement and welfare of citizen. In this paper, we develop machine learning algorithms for forecasting UK housing Price, and find an optimal algorithm that forecasts housing price accurately on the premises of the presence of many features or covariates. After applying correlation analysis to remove correlated variables in order to avoid multicollinearity, thereby increasing the statistical power, a novel method of using regression analysis to first of all understand and select statistically significant features for the various regions in England based on North South divide is adopted. These features are then used in the machine learning algorithm to further increase the statistical power of the algorithm, increase the level of accuracy for each of them and ultimately increase the predictive values for the algorithms.
The model construction involves 3 stages: 1- correlation analysis to identify and remove correlated variables thereby avoiding multicollinearity and increasing the statistical power of the linear regression, 2 - using linear regression to determine variables that are statistically significant and 3 - building the machine learning algorithms based on the variables that are statistically significant from the linear regression. A comprehensive dataset of UK Paid housing Price from 2010 to 2019 was linked to a number of other datasets to generate a total 21 variables or features used for the models. Catboost, Gradient Boosting, Bagging, Random Forest, Extra Tree all achieved the excellent models performance result in all the regions considered. The comparison of the seven models showed that Extra Tree algorithm consistently achieved the best performance in term of level of accuracy in all the regions. K-Nearest Neighbours (KNN) is the only algorithm with less than 50% level of accuracy. Noticeably, the regions considered had varying or differing insignificant variables, implying that although many variables are common (statistically significant) to all the regions, there are regional differences and impact when modelling or predicting housing prices. This study validates the practicability of developing a machine learning methodology for the prediction of housing price. This research offers a reference for future house price prediction based on machine learning.

Authors: Park Hoon Min , JUNG HYUN-MIN , Lee Dae Hee , Lee Joon-Seong , YOON DAL-HWAN , Jeon Dong Hwan , LIM TAE-YEUNG
Published: April 2024

In this paper, a 100CMM regenerative thermal oxidizer (RTO) system based on a high heating device for low-emission combustion is implemented at a volatile organic compound (VOCs) gas generation workplace. Existing RTO has a structure that repeats the inflow and discharge of VOCs gas into a cylindrical drum-type rotating disk and has excellent energy efficiency with a heat recovery rate of 95% or more. However, when used for a long time, there is a problem that rotation stops or explodes due to the discharge of pollutants due to dust and thermal expansion due to high temperature of 800℃. To overcome this, a RTO based on a high heating device was developed to reduce low-emission combustion emissions and energy use. Through 177 hours of demonstration time, the oxidation efficiency of VOCs was 98.87%; the waste heat recovery rate was reduced by 95.78%, the fuel consumption was reduced by 21.95%, and the nitrogen oxide concentration was 3.9 ppm

Features of Distribution and Spread of Hyalomma marginatum (Acari, Ixodidae) Ticks in the Crimean Hemorrhagic Fever Focus in the Territory of Russia
Authors: Tsapko N. V. , Klimova L. I.
Published: April 2024

The review provides the summarized and updated information on the current distribution of the tick Hyalomma marginatum in the natural Crimean hemorrhagic fever (CHF) focus in Russia. The work is based on the analysis of numerous literature sources, as well as the evidence from the personal collecting of ticks during long-term field research. In addition, the collection of ticks of the Stavropol Research Anti-Plague Institute of the Rospotrebnadzor and the database of H. marginatum collections in various regions of southern Russia were used. When delineating the boundaries of the H. marginatum areal and the CHF focus, we also deployed maps of the epidemiological survey of the focus, weekly and annual final reports on the CHF incidence from the Rospotrebnadzor Administrations. H. marginatum inhabits all regions of the Southern Federal District and the North-Caucasian Federal District, as well as the Crimean Peninsula and the south of the Saratov Region. The northern border of the areal reaches the Lugansk People’s Republic, Rostov, Volgograd, and Saratov Regions. H. marginatum is widely disseminated in the territory of Kalmykia and the Astrakhan Region. In the North Caucasus, it inhabits the entire flatland up to the foothills of the Greater Caucasus. The tick is widely distributed in the Stavropol Territory, populating the entire region. In the mountainous part of the Krasnodar Territory, this species is absent, but common in the rest of the areas. Beyond that, it is found on the Black Sea coast. In Karachay-Cherkessia, Kabardino-Balkaria, North Ossetia and Ingushetia, the tick lives in the northern steppe regions of the republics, in some places it invades the foothills. In Chechnya and Dagestan, the species widely inhabits the steppes and semi-deserts of the Terek-Kuma Interfluve. Moreover, in Dagestan, H. marginatum lives across the plain and foothill territory of the republic and even reaches the highlands up to a height of more than 2000 m above sea level. In addition, it is widely disseminated on the Crimean peninsula, both the flatland and the mountainous part.

At present, bacteriophages are considered as an alternative to antibiotics in prevention and treatment of bacterial infections, in particular cholera.

The aimof the work was to demonstrate a method to obtain synthetic bacteriophage againstVibrio cholerae. Vibriophage N4 was selected as a subject for the study.

Materials and methods. The genome sequence of vibriophage N4 (38.5 kb) was taken from the NCBI GenBank database. The sequence was divided into gene blocks of 1500–2000 bp. The gene blocks, in turn, were split into oligonucleotides. Sequence partitioning was carried out using the BAC-browser software that we have developed. Oligonucleotides were chemically synthesized; gene blocks were assembled from them. After that, the complete genome of vibriophage N4 was synthesized from the obtained gene blocks. The assembly of the synthetic genome took place in two stages. At the first stage, gene block cassettes of 5–7 pieces with sizes ranging from 7 to 10.5 thousand bp were generated via homologous recombination in yeast. The resulting cassettes were then amplified and used forin vitroassembly using 5’-3’ exonuclease and thermostable DNA polymerase. The resulting preparation was used for electroporation ofV. choleraecells.

Results and discussion. The synthetic genome of vibriophage N4 was delivered into theV. choleraestrain M818 O1 biovar El Tor using electroporation. As a result, the formation of lytic plaques on the lawn ofV. choleraewas observed. The range of technologies we have developed: software for assembly design, enzymes and buffers for the synthesis of gene blocks and their crosslinking by homologous recombinationin vitro, the method for producing large-sized assemblies in yeast can be used to obtain artificial bacteriophages with a rational genome design.

The review features the situation on Crimean-Congo hemorrhagic fever (CCHF) in the world and the analysis of the epidemiological and epizootiological situation in the Russian Federation in 2023. The number of CCHF cases (26) in Russia was 2.3 times less than in 2022, and 71.6 % lower than the long-term average (in 2013–2022 – an average of 88.8 cases per year, mortality (8 %) is 2.4 times higher than the long-term average (3.3 %). The epidemically significant indicator of the abundance of the main vector of the CCHF virus, ticks Hyalomma marginatum, was 5 times higher than the threshold value (abundance index for cattle – 15.5) at long-term observation points in April. For the first time, one case of CCHF disease was registered in a new epidemically active territory – in the Botlikh and Novolaksky districts of the Republic of Dagestan. For the first time in the Zaporozhye Region, RNA of the CCHF virus was detected in ticks H. marginatum and Rhipicephalus rossicus. Markers of CCHF virus were found in 0.67–18.27 % of samples, CCHF virus variants of the genetic line Europe 1 were circulating on the territory of Russia in 2023. According to the forecast of the epidemic situation for 2024, CCHF morbidity is likely to increase in the south of the European part of Russia. The recommendations for undertaking preventive measures have been provided.
