Authors: Okwuraiwe Azuka Patrick , Osuntoki Akinniyi Adediran , Ebuehi Osaretin Albert , Audu Rosemary Ajuma
Published: September 2022

At least 33 million people worldwide are living with human immunodeficiency virus (HIV) infection, and about 20-30% of these are also infected with hepatitis C virus (HCV). Co-infection with HIV and HCV is a major public health concern. Co-infected persons develop cirrhosis and end-stage liver disease more quickly than individuals infected with HCV only. The particular HCV strain or genotype is a major factor for HCV prognosis. The pattern of HCV genotypes in a cohort of HIV/HCV co-infected patients was investigated. One hundred (100) adult patients were recruited from the Nigerian Institute of Medical Research (NIMR), Yaba, Lagos, with age ranging from 18 to 65 years (58% male). Upon recruitment, they were placed on appropriate antiretroviral drugs; 300 mg tenofovir (TDF), 200 mg emtricitabine (FTC) plus 600 mg efavirenz (EFV) once daily dosage. HCV genotyping was done using the Linear Array hepatitis C virus genotyping kit (Roche Molecular Systems, Inc. USA). HCV genotyping revealed prevalence of genotypes 1 (65.6%) and 4 (34.4%), respectively. These are the hard-to-treat genotypes that previously required a long duration of HCV therapy until newer drugs were introduced. The nature of HCV genotypes in HIV/HCV co-infected people has serious implications for further HCV therapy. These findings are pertinent for decisions about the best possible time for and kind of HCV treatment in the setting of co-morbid HIV infection.

Published: September 2022

Retro-rectal tumors are asymptomatic in most cases. Rarely they manifest as a rectal syndrome as in the case of our patients, or as a result of superinfection or malignant degeneration. Positive diagnosis is based on digital rectal examination, rectoscopy, echo-endoscopy and especially pelvic MRI and CT scan. Once the diagnosis has been made, surgical removal is required as soon as possible. Several surgical approaches have been proposed: perineal or transacral approach (adopted in our first case); abdominal approach or combined approach. The decision of the approach depends on the size of the tumor, its location and its histological nature. In case of malignant degeneration, the prognosis is poor.

We report 3 cases of retro-rectal tumors operated on in the department of digestive cancer surgery and liver transplantation of the CHU Ibn Rochd of Casablanca with the support of data from the literature.

Impact of hydrocarbon oxidizing strains Serratia grimesii and Bacillus sp.3 on microcenosis of molluscs and ecosystem components under oil pollution impact
Authors: Kanieva Nuria Abdrakhimovna , Badzhaeva Olga Vladimirovna , Popova Ksenia
Published: September 2022

Bivalved molluscs are natural filter feeders of the aquatic environment due to their physiological characteristics. Passing sea water containing emulsified oil through them, they bind its droplets in pseudofeces, thereby accel-erating water self-purification. Mussels prove to be resistant to oil pollution. Experiments have shown that in aquariums with mussels the content of petroleum hydrocarbons decreases faster than in the tanks without mussels. The interaction of mussels with oil has been studied in detail. It has been established that when passing through the body

of mussels the group composition of oil products changes. Oil resignification is noted, which is also observed during its natural weathering. Currently, for the post-purification of natural ecosystems from oil pollution, the method of introducing active hydrocarbon-oxidizing microorganisms is widely used, often with the simultaneous incoming of additional biogenic elements, the so-called bioaugmentation. In this regard, the study of the interaction of oil-oxidizing microorganisms and molluscs is of practical and scientific interest. The aim of the work was to study the interaction

of hydrocarbon-oxidizing microorganisms on molluscs Unio and other components of the microecosystem when modeling the process of oil pollution. A study was made of river water, soil and molluscs Unio from model microecosystems for contamination by saprophytic and hydrocarbon-oxidizing microflora with the additional introduction of hydrocarbon-oxidizing microorganisms – Serratia grimesii and Bacillus sp.3 under conditions of Caspian oil pollution.The values of the bacterial composition of saprophytic and hydrocarbon-oxidizing microflora obtained in the experiment suggest that the processes of restoration and reclamation of a water body take place due to the structural and functional organization of ecosystems and communities.

Authors: Moi Subhas Chandra , Pal Pradip Kumar , Bandyopadhyay Asish , Rudrapati Ramesh
Published: September 2022

This paper presents the study of effect of heat input on the joint quality of tungsten inert gas (TIG) welded specimens. Three different heat input combinations selected as low heat (0.75kJ/mm), medium heat (0.90kJ/mm) and high heat (1.05kJ/mm) have been applied during the operation of TIG welding process on 316L austenitic stainless steel. Welded joints being prepared using a semiautomatic TIG welding machine, the effect of heat input is investigated on the weld bead geometry and mechanical-metallurgical characteristics of the joints. It is observed that as heat input increases, the width of weld bead increases, where as height of weld bead decreases with increasing heat input. Tensile strength as well as hardness increases with increase of heat input up to a threshold value and thereafter it start decreasing. The results of the investigation indicate that the joint prepared using medium heat input depicts higher tensile strength, percentage elongation, yield strength and higher micro hardness value than those joints made using low and high heat input due to smaller dendrite size and lesser interdendritic spacing in the weld zone and formation of very fine skeletal δ-ferrite in plain austenitic matrix. A large number of very fine and shallow dimples are observed in SEM fractograph of the joint made using medium heat input.

Published: September 2022

Surface roughness is often used as a measure to identify surface integrity of machined parts. The objective of this study was to optimise part surface roughness by investigating the effects of cutting speed, feed rate, depth of cut and tool nose radius on the surface roughness of Aluminium 6061. A five-level L25 Taguchi orthogonal array was modified to accommodate a four-level process parameter. The optimization was conducted on the prediction model generated by use of Response Surface Methodology (RSM) together with Analysis of Variance (ANOVA), and confirmation test validated the predicted values obtained from the Genetic Algorithm (GA). The best combination of parameters for minimum surface roughness was found to be a cutting speed of 250 m/min, feed rate of 0.03 mm/rev, depth of cut of 0.2 mm and tool nose radius of 0.503 mm. The study proves the efficacy of the GA approach in optimisation of machining parameters for improved surface roughness.

Authors: Hendronursito Yusup , Isnugroho Kusno , Birawidha David Candra , Amin Muhammad
Published: September 2022

Hammer-mill crusher is the main component of crushing machine, used to crush the material into smaller size. In this study the crusher was produced by casting in an induction furnace, which composition consisted of 1.64% C, 8.77% Mn, 2.56% Cr, and 3.75% Cu. Unfortunately, the production process frequently yielded undesirable defects such as blowhole, gas porosity and smooth - walled cavities, and the welding process was required to repair such defects. This study aimed to determine the welding parameters for hammer-mill crusher welding with Shielded Metal Arc welding (SMAW) process that covered the effect of welding current of 90A, 120A, 150A, welding speed of 0.8 mm/s, 1 mm/s, 1.7 mm/s and filler metal of AWS A5.5 (E7016) and AWS A5.13 (E7-UM-300K). The qualification standard for welding refered to The American Society of Mechanical Engineers (ASME) Section IX Welding and Brazing Qualification. The testing refered to ASME IX QW - 140 (purpose of the testing and inspection of welds) for tention test (QW-141.1) and visual examination (QW-144), ASME IX QW – 190 (other tests and examination) for Radiographic examination (QW – 191). The hardness test was performed to determine whether the hardness of weld pool is the same or close to the value of the hammer-mill crusher hardness. This parameter was important considering the function of hammer-mill as hard material crusher. The results showed that the optimum welding condition are: welding speed of 1 mm/ s, welding current 120A and filler metal AWS A5.13 (E7-UM-300K). The best results of mechanical properties include hardness 254 HV, elasticity modulus 277.261 MPa, and tensile strength283.605 Mpa.

Authors: Lian Oh Chai , Wee Lee Siong , Md Zain Mohd Raizamzamani
Published: September 2022

This research focuses on the mechanical properties of Engineered Cementitious Composites (ECC). Few ECC mixtures were designed and tested under direct tensile test and compression test. The novelty of this research is the utilization of available local materials in Malaysia, which is significantly different from the ingredients employed by previous researchers in the US, Japan and other countries. The ingredients used for ECC mixtures in this research were Ordinary Portland Cement (OPC), ground granulated blast-furnace slag (GGBS), sand, water, superplasticizer (SP) and polypropylene (PP) fibers. Local ingredients such as river sand and GGBS were used to replace micro silica sand and fly ash in the standard mix of ECC. Test results demonstrated that tensile ductility and compressive strength in ECC improved as compared to normal concrete. The effect of cement replacement ratio and fibres content are discussed based on the performance in both tensile and compressive properties. Comparison with previous studies was carried out to identify the weaknesses of the current ECC mixture, so that improvement can be done in future studies. The best ECC mixture is proposed according to the performance in mechanical properties.

Authors: ÖZCAN Cansu , GÜCÜM Yrd.doç.dr.berna
Published: September 2022

Examination of hands-on activities in science education necessitates reforms that enable development and improvement in science programs, which coincides with the dynamic structure of education. Distance education, which is a result of the pandemic period that has affected the whole world since the beginning of 2020, has also affected science education and the studies carried out in this period have gained im-portance. Investigation of the effects of inquiry approaches on science learning especially in the distance education process can be considered as an important contribution to the literature. In this respect, the re-search aims to examine the effect of the guided inquiry approach on students' achievement and retention in the sixth-grade science course when the effects of reading comprehension skills are controlled. The sample of the research is comprised of sixth graders attending a public school. The students were assigned into two groups as experimental and control groups. In the experimental group, the guided inquiry approach was applied and in the control group, the traditional method was used. The Systems in Our Body Achievement Test, which was developed as a data collection tool in the research, was applied to both groups as an immediate post-test and delayed post-test to determine the achievement of the students. As a result, it was concluded that the inquiry approach applied in the distance education process, where reading skills were statistically controlled, increased the success of the students in the science lesson compared to the traditional application

Abstract in English

Clean drinking water supply is a major concern to the population of the urban municipality of Boké, Republic of Guinea. This study is aimed to investigate the favourable geological structure for the accumulation of groundwater in Boké. Apparent resistivity data was collected by using the Schlumberger-type vertical electrical sounding technique. The apparent resistivity values were obtained on a bi-logarithmic scale in which the distances AB/2 were plotted on the abscissa and the resistivities are on the ordinate. It found the number of terrains and their characteristics (resistivity and thickness) in the area and the behaviour of the current in the soil through a curve. The results show that the structures favourable to the accumulation of groundwater were fractured dolerites, cracked shales and cracked or crushed sandstones. The sandstones were the most important in terms of the amount of water. They are located at a depth of more than 100 metres. It was also found that dolerites and shales are located at shallower depths (less than 100 m).

Easy Risk Assessment for Unmanned Aircraft Systems: Outline of the Method
Authors: Wyszywacz Wiktor
Published: September 2022

The key element of safety systems in air transport is risk management. The rules for the safety of unmanned aircraft system (UAS) operations are established by the Commission Implementing regulations (European Union [EU]) and national regulations. Risk assessment is the foundation of all activities. The broadest scope is covered by the special category of flights for which the Joint Authorities for rulemaking on Unmanned Systems (JARUS) developed the Specific Operations risk Assessment (SORA) analysis. The primary purpose of the SORA analysis is to create a comprehensive safety portfolio, which is attached to the National Aviation Authority (NAA) application for permission to perform specific category flights. Aviation authorities may accept the use of other risk analysis methods to demonstrate risk reduced to a safe level. Easy risk Assessment (erA) for UASs is an attempt to determine the risk for UAS flights in a simple way by considering a range of factors influencing risk management in a similar way to the SORA. It is an uncomplicated method, which determines threats and their sources, provides risk management, and allows the determination of the level of risk tolerance. The ERA is intended to be an alternative to the SORA methodology for those looking to carry out risk assessment.

Authors: Osiewicz Maciej , Cieślak Sławomir , Bielecki Marcin
Published: September 2022

The article presents an experimental method of determining the geometric properties of jet engine rotor airfoils based on modal vibration testing. The procedure is based on adjusting the results of analytical calculations to the laboratory outcomes. Experimental tests were carried out on a set of 20 jet engine fan blades made of AL7022-t6 aluminium alloy. Each blade differed in weight and geometric dimensions within the accepted design tolerance. Numerical analysis of five airfoils that differed in thickness was performed. Modal vibration test results were summarised and compared with the results obtained by the numerical method. The comparison revealed a high similarity of the frequency and form of vibrations acquired by numerical simulation for each of the blades in relation to the executed vibration testing. Based on the verification of the theoretical model with the results obtained through experimental testing, conclusions were drawn about the object’s dynamic behaviour and its technological quality and geometric properties, whereby each of airfoil was probably thinned.

Authors: Козин Виктор Михайлович , Лебедев Артем Алексеевич
Published: September 2022

Показаны возможности повышения энергоэффективности резонансного метода разрушения ледяного покрова, осуществляемого судами на воздушной подушке. Поясняются физические основы этого метода разрушения льда. Резонансный метод может использоваться для продления навигации на внутренних водных путях, разрушения ледяного покрова в замерзающих портах, заливах и бухтах посредством более раннего вскрытия рек и водохранилищ. Как показала зарубежная и отечественная практика эксплуатации судов на воздушной подушке в ледовых условиях, резонансный метод может успешно применяться для предотвращения наводнений посредством разрушения возникающих в периоды ледостава и ледохода ледяных заторов и зажоров. Подобные ледовые осложнения, как правило, возникают в условиях мелководья или на предельно малых глубинах, где не могут работать ледоколы из-за их большой осадки. Амфибийные свойства судов на воздушной подушке позволяют успешно выполнять ледокольные работы в этих условиях. Показаны способы маневрирования СВП при разрушении заторов вблизи населенных пунктов, где проведение взрывных работ для их ликвидации из-за риска повреждения зданий невозможно. Установлено, что эффективность резонансного метода можно повысить, используя интерференции изгибно-гравитационных волн, возбуждаемых в ледяном покрове одновременно несколькими судами. Приведены защищенные патентами РФ на изобретения и подтвержденные экспериментами в лабораторных и натурных условиях результаты эффективного использования групповой работы судов на воздушной подушке (движение судов фронтом, кильватерным строем и пр.). Показаны способы повышения энергоэффективности разрушения ледяного покрова: использование ледовых условий, разработка дополнительных конструкций и оснащение ими судов на воздушной подушке.

Introdução: As mulheres indígenas costumam enfrentar formas diversas de discriminação em virtude do gênero e etnia, interferindo, assim, na qualidade de vida, nas taxas de morbidade e mortalidade e no acesso aos serviços de saúde. Objetivo: Compreender o processo saúde-doença das mulheres indígenas na América do Sul. Método: Tratase de uma revisão integrativa sistemática com pesquisa nas bases de dados ScieLO, PUBMED e LILACS utilizando quatro descritores em ciências da saúde (DeCS) nos idiomas português, espanhol e inglês. Sendo aplicadas as seguintes combinações “saúde AND indígenas AND mulheres AND Brasil” e “saúde AND indígenas AND mulheres AND NOT Brasil”. Os critérios de inclusão foram artigos em português, inglês e espanhol, que abordassem estritamente a relação entre saúde e mulheres indígenas da América Latina nos últimos cinco anos. Resultados: Foram identificadas 3337 publicações e, após a aplicação dos critérios de inclusão e exclusão, foram selecionadas, ao final, 28 artigos, a maioria publicada no Brasil (46,43%), seguido de Colômbia (17,86%) e Paraguai(14,29%). A partir dos artigos selecionados foram extraídas 03 categorias: Enfermidades gerais, Acesso aos serviços de saúde e Aspectos culturais. Conclusão: As barreiras culturais, geográficas, socioeconômicas e linguísticas resultam em consequências negativas para a saúde da mulher indígena como: infecções, doenças sexualmente transmissíveis, altas taxas de mortalidade materna e aumento da presença de doenças crônicas. Dessa forma, percebe-se uma negligência no cuidado dessas mulheres. Urge a formulação de políticas públicas e o reforço das já existentes, a fim de combater a desigualdade e promover a igualdade no cuidado, respeitando a interculturalidade.

Authors: Inaniyan Yashasvi , Tak Pooja , Naga Pramila , Purohit Priyanka
Published: September 2022

The kinetics of oxidation of four vicinal, four non-vicinal diols by tributylammonium chlorochromate (TBACC) has been studied in dimethylsulphoxide (DMSO). The main product of oxidation is the corresponding hydroxycarbonyl compound. The reaction is first order each in TBACC. Michaelies-Menten type of kinetics is observed with respect to the diols. The reaction is catalysed by hydrogen ions. The hydrogen ion dependence is taking the form: kobs = a + b[H+]. The oxidation of [1,1,2,2-2H4] ethanediol exhibits a substantial primary kinetic isotope effect (kH/kD = 5.81 at 298 K). The reaction has been studied in nineteen different organic solvents and the solvent effect has been analysed using Taft's and Swain's multiparametric equations. The temperature dependence of the kinetic isotope effect indicates the presence of a symmetrical transition state in the rate-determining step. A suitable mechanism has been proposed.

Authors: Pinkovetskaia I. S.
Published: September 2022

The article deals with the problem of development and methodological tools application for a comprehensive assessment of regional features of the digital and communication technologies use by organizations in Russia. The purpose of the study is to evaluate the indicators characterizing the use of digital and communication technologies in organizations located in different Russian regions. The official information of Rosstat agency for 2020 was used as empirical data. Modeling of empirical data was carried out according to the author’s methodology, based on the development of density functions of the normal distribution of three indicators by region. The variance analysis of indicators by regions with their minimum and maximum values was based on the ANOVA method. The study showed that about 82.2 % of organizations used digital technologies. The level of use of communication technologies was significantly lower. 66.1 % of organizations used the Internet to provide statistical, tax and other reporting. The share of organizations involved in electronic procurement for state or municipal needs was 38.6 %. Lists of regions were compiled in which the maximum and minimum values of indicators characterizing the use of digital and communication technologies by organizations were noted in 2020. The results of the work can be used in the activities of federal and regional structures related to the regulation and planning of the development of these technologies and the justification for allocating additional resources to regions with a low level of their use.

Published: September 2022

China and Russia aim to increase bilateral trade to 200 billion USD by 2024. In addition to the enormous potential for cooperation in the field of traditional energy and mineral products, agriculture, investment and engineering contracts, as well as scientific and technological cooperation, have developed rapidly. The latter is expected to become a new pillar of Sino-Russian economic and trade cooperation. The subject of this study is the ongoing innovation in the banking sector in the organization of settlements in the yuan between Russia and China. The international system of settlements and payments includes the transfer of financial information and the distribution of assets, it is a key link in global economic cooperation. However, the Sino-Russian system of payments and settlements is severely restricted by the United States. Against the background of abuse of the US financial hegemony and acceleration of internationalization of the yuan, the settlement system between China and Russia faces real demand for dedollarization, which lead to mutual settlements between China and Russia in the national currency, especially the RMB calculations. Based on the analysis of the actual and potential demand for Chinese yuan in the Russian market, the political environment of settlements in yuan and the technical conditions for calculating the amount, the authors concluded that the prospects for the Sino-Russian system of settlements and payments in yuan are high.
ELECTRE methodology and automation of alternative ranking
Authors: Tereliansky P. V. , Kuznetsov S. Yu.
Published: September 2022

The authors consider the stages of applying the ELECTRE methodology: multi-criteria ranking of alternatives to. This approach assumes taking into account the values of the features characterizing the evaluated alternatives and the significance levels of these features. Based on these expert assessments, the indices of agreement and disagreement are calculated. Their values determine the validity of the assumption of the superiority of alternatives over each other. The implementation of strictly defined stages of the methodology makes it possible to identify the order of dominance of alternatives and rank them in accordance with the priorities of the decision-maker. The algorithms of ELECTRE family offers a deterministic approach to decision-making, in which methods and models are considered as practical means of tactical and strategic analysis of the situation. Automated decision support systems implementing these methods make it possible to document an understanding of the actual preferences of decision makers. The ELECTRE I method uses verbal statements stating binary relationships between alternative strategies. Binary relations are expressed by the indices of agreement and disagreement. The results obtained indicate effectiveness of the methodology under study.

The subject of research is the Internet trading in the American and European financial markets for individuals from the Russian Federation. The relevance of the topic is due to the huge influx of Russian private investors into the global financial market over the past few years, caused by the simplification of the process of opening brokerage accounts, automation of taxation, the possibility of trading via web terminals, as well as significantly changed conditions of online trading in 2022. The whole work is the development of a report on investing in the financial markets of the United States of America and the European Union for citizens of the Russian Federation. The study was conducted using the methods of systematization, grouping and comparison, with their help, analysis and generalization of the results obtained were carried out, conclusions were drawn. It has been established that in the current geopolitical situation and the restrictive measures taken by many multinational banks and companies, private investors of Russian origin have risks of freezing their own assets on brokerage accounts, which can be reduced by opening a brokerage account in companies registered in the territory of countries friendly to the Russian Federation. The article suggests two least risky options for investing in securities of issuers from Europe and USA.

Authors: Jiang Yanlong , Renata Hans
Published: September 2022

Cotylenin A and fusicoccin A are two flagship members of the fusicoccane diterpenoid family that are capable of acting as molecular glues to stabilize the interaction between the 14-3-3 proteins and their clients. Herein, we report a concise che-moenzymatic synthesis of cotylenol, the aglycone of cotylenin A. Key features that contribute to the brevity of the route include the union of two cyclopentene fragments in an allylative coupling, a one-pot Prins cyclization-transannular hydride shift sequence, and a late-stage enzymatic oxidation to install the key tertiary alcohol at C3.

Dicarbofunctionalization is an important efficient synthetic technique for adding two chemical moieties across an alkene. Here, a novel method of reductive dicarbofunctionalization has been developed using a single alkenyl triflate as the electrophile, combined with an unactivated alkene. The reaction does not require an external auxiliary and proceeds with complete regioselectivity.
Physics-Guided Curve Fitting for ab Initio Diatomic Spectroscopy
Authors: Irikura Karl
Published: September 2022

When using ab initio calculations to predict the spectra of diatomic molecules, discrete ab initio data must be converted to continuous form. As in other applications of interpolation throughout science and engineering, high-resolution (i.e., fine-mesh) data are desirable so that the method of interpolation does not affect the final results. However, high-resolution data are seldom available, because of their high cost. Current practice to is use splines, polynomials, or Morse-like fitting functions for interpolation and even for extrapolation. The choice is arbitrary and affects the spectroscopic results more than is generally recognized. Here we suggest an alternative procedure, in which the physics of the problem is leveraged to provide more robust results. A high-resolution data set, from a less costly ab initio model of the system of interest, is used as a guiding function. The residuals must still be fitted using splines or polynomials, but the smaller magnitude and weaker structure of the residuals leads to improved stability and accuracy of the spectroscopic results. When two or more guiding potentials are available, they can be used to guide the selection of geometries to be computed at high level, thus improving computational efficiency.

Published: September 2022

Background: This study was conducted to evaluate the surface roughness and dimensional accuracy of commercially obtainable alginate impression material in terms of imbibition after immersion in two different media. Materials and method: Two disinfecting agents, ethanol 70% and povidone-iodine 4%, were used to access the dimensional accuracy and surface roughness of alginate impression material. Weights of specimen discs of alginate impressions were measured before and immediately after immersion to gain a measure of imbibition. For surface roughness, disinfected specimens rectangle was examined before and after disinfection. Results: Minimal changes in weight were observed after disinfection, but a statistically non-significant difference was found before and after immersion. It did not affect the surface roughness of alginate impression material Conclusion: Disinfection of alginate impression material with ethanol and povidone iodine had no significant effect on dimensional accuracy and surface roughness.
Factors influencing the system of legal responsibility: problem formulation
Authors:   University of Prosecutor’s Office of the Russian Federation, Kuzmin I.A.
Published: September 2022

The problem of factorial influence on the system of legal responsibility, insufficiently explored and actual for modern jurisprudence, is studied. Based on the previous research results, the author raises the question of the need to develop a conceptual vision of the system of factors influencing the system of legal responsibility and its subsystems. The main meanings of the term “legal factor” are revealed. The author’s interpretation of the concept of “factor of law” is proposed. The disadvantages of the “traditional” approach to the differentiation of factors influencing the system of legal responsibility in the spheres of public life are indicated. In particular, it was noted that such an approach has an excessively high degree of generalization and does not provide for the possibility of the existence of complex and mixed factors (socio-political, economic-ideological and others), as well as extra-social factors (natural, technical and others). It is determined that, along with the indicated (general) factors, special factors – factors of law – have a direct impact on the system of legal responsibility. Examples of the positive and negative impact of certain factors of law on the system of legal responsibility are given using official statistics and information about the problems of lawmaking and law enforcement. Recommendations are given on the implementation of factor analysis in relation to the subsystems of legal responsibility, dichotomous series of factors to be taken into account are proposed, semantic blocks for identifying the degree of factor impact are named. In general, the methodological starting points for further knowledge of the factorial prerequisites of the system of legal responsibility are justified. The results of the research are summed up.
