Summary. Purpose of the study. Formulation of the concept of creating a system for monitoring the health status and risk management of personnel of enterprises supervised by the Federal Medical and Biological Agency of Russia, and the population of adjacent territories. Results. The proposed concept provides for the formation of a Register – a distributed database of personnel of enterprises supervised by the FMBA of Russia and the population of adjacent territories. In the structure of the Register (code name “FMBA-health”) the main link is the PERSON section. Each person included in the Register (employee of supervised enterprises or residing in territories supervised by FMBA of Russia) has his own strictly unique code. Identification data about the person is linked to this code (subject to the requirements of the Personal Data Law). The register provides the following main data sections: “Health” (with possible subsections “Oncology”, “Occupational diseases”, “Disability”, etc.), “Enterprise” contains information about the employee of the enterprise (or part of it in the pilot project) and working conditions, associated with the analyzed hazard factors, “Place of residence” (with data on natural or technogenically modified characteristics of the natural environment). The mathematical theory of assessing the total production risk is presented on the basis of published works with the participation of the authors. The most developed and actually functioning is the ESCID system of the FMBA of Russia – collecting information about the radiation factor. The theoretical provisions of the concept of man-made risk management are given within the framework of a three-tier system of social protection and medical assistance to personnel of production facilities with hazardous and especially hazardous working conditions: the first link is related to working conditions, the second – with the provision of specialized medical care, including in-depth early diagnosis for medical reasons, and the third – associated with the possibility of compensation payments to sick employees based on establishing a cause-and-effect relationship between working conditions and a diagnosed disease (insured event).

Published: April 2024

Purpose. Analysis of the dynamic characteristics of the cargo in the presence of the speed of its carrier, taking into account the influence of the external environment and the determination of factors that affect the operational characteristics and parameters for the dynamic system control. Methodology. An approximate analytical approach to solving the nonlinear problem of external ballistics of a system with time-dependent parameters, which is implemented using the asymptotic perturbation method, and a numerical algorithm for modeling a dynamic process using a 3D software complex and the finite element method, which allows to visualize the nature of the flow around the object under wind load conditions. Findings. An analytical approach to solving the nonlinear problem of external ballistics of a system with time-varying parameters is proposed, as well as a numerical model, solution and visualization of a dynamic process that can be applied in problems of mathematical physics and engineering calculations. Originality. The use of an approximate analytical approach to solving the nonlinear problem of external ballistics, which includes a system of time-varying parameters, is a significant innovative step. For the first time, a three-dimensional distribution of the free fall parameters under atmospheric conditions was obtained depending on the time of free fall under the condition of an initial velocity different from zero. Obtaining the characteristics of the distribution, taking into account the aerodynamic quality of the object, made it possible to adapt the methods of analytical mechanics and differential equations with variable coefficients to the solution of the applied problem. The obtained characteristic three-dimensional surface allows to perform a study of the aerodynamic quality of the object under study using numerical methods and to visualize dynamic processes in three-dimensional space in order to obtain a qualitative picture of the perturbation of the object by the air flow. This integrated approach to the study of ballistic characteristics of cargo forms the scientific principle to perform engineering calculations to solve the problem of controlling dynamic systems. Practical value. An approximate analytical approach and a calculation model of the dynamic process of a mechatronic unmanned system make it possible to increase its efficiency in the presence of an initial speed and ensure the accuracy of the application of ballistic cargo delivery systems in real operating conditions.
Study of the influence of the mode of rotation of pipe in the cold rolling process on the microstructure, mechanical properties and accuracy
Authors: Нolovchenko O
Published: April 2024

Goal. Obtaining experimental results on the influence of the turning mode during cold rolling on the microstructure, mechanical properties and accuracy of the geometry of the pipes to improve their quality. Method. Experiments were carried out on equipment used in production and having appropriate inspections. We used a grinding machine, a device for electrolytic etching, a MIM 7 microscope, and a press for stretching samples. The accuracy of the geometric dimensions was determined using tube micrometers. Rolling route 25×2.5 mm → 16×1.5 mm. Steel 08Х18Н10Т. The results. Two rotation modes were performed: mode 1 – feed 2, 3, 4, 5 mm in front of the straight one, and the rotation before the reverse movement of the cage; mode 2 – feed 2, 3, 4, 5 mm in front of the straight, and turn in front of the straight and reverse movement of the cage.For mode 2, in comparison with mode 1, the grain size near the inner surface of the pipes is visually smaller than near the outer surface.The strength limit, yield strength and relative elongation for modes 1 and 2 were found to be close in value.With regard to the accuracy of the geometry of the pipes, it was determined that in mode 2 compared to mode 1: – the transverse thickness of the pipes decreases by 1.4–1.6 times; – the ovality of the pipes is reduced by 1–2 times (feeds from 2 to 5 mm); – the spread of the diameter along the length of the pipe decreased almost twice. Scientific novelty. For the first time, new experimental industrial data on the influence of the rotation mode on the microstructure were obtained. It is shown that the grain size near the inner surface of the pipes is smaller than near the outer surface.For the first time, obtained experimental industrial data on the effect of the tube rotation mode on the values of strength limit, yield strength and ultimate elongation showed that the rotation mode did not affect their change.Additional experimental dependences on the influence of the pipe rotation mode on the transverse variation, ovality and spread of the outer diameter of the pipes during cold rolling of the pipes were obtained - the reduction of the transverse variation was 1.4–1.6 times, ovality 1–2 times, and the diameter variation was almost 2 times. Practical significance. The obtained results are needed in the development of technologies for the production of pipes with increased quality requirements (microstructure, heterogeneity, ovality, diameter dispersion).

Purpose. To perform an analysis of the stress-strain state in cylindrical drums of mine hoisting machines. To study the impact of the stiffness parameters of the elastic lining, made of composite material, and the drum's flange on the stress distribution in its shell. Based on the analysis results, it is necessary to identify the optimal design characteristics of the lining that would minimize these stresses. The methods. A theoretical analysis of existing scientific research in this field of mechanical engineering has been conducted. Based on it, an algorithm was developed to determine the most effective lining parameters. It was found that applying semi-analytical calculation methods allows for a more accurate assessment of the influence of the geometric and stiffness properties of the design on the intensity of the stress-strain state in the drums of mine machines. Findings. The analysis of the stress-strain state in the cylindrical drums of mine hoisting machines revealed two key stress zones in its shell, the intensity of which directly depends on the radial and bending stiffness of the flange. The application of the developed algorithm makes it possible to significantly reduce the level of stress in the metal shell of the drum, on average by about 20%. This will increase the strength and durability of the structures. The originality. The study proposes an approach to determining the optimal parameters of the elastic lining. For the first time, it has been demonstrated how using an elastic coating made of composite material can improve lifting characteristics and extend the operational life of the ropes. Practical implementation. The application of the research results should contribute to increasing the efficiency and reliability of mine hoisting machines, as well as reducing the risks of their operation being interrupted due to reduced stresses in the metal shells of the drums.

Published: April 2024

Understanding Islam poses a significant challenge for newly converted individuals and groups, underscoring the necessity of companionship and guidance to facilitate their learning and exploration of faith. Recognizing this imperative, the Indonesian Chinese Islamic Unity Institute (PITI) in Surabaya has initiated mentoring activities tailored specifically for new converts of Islam. Employing a persuasive communication approach between mentors and converts, the program aimed to deepen their understanding of faith.  This study evaluated the effectiveness of persuasive communication in the development of conversion to Islam at the Indonesian Chinese Islamic Association Institute in Surabaya. Using qualitative research methods with a descriptive approach, in-depth interviews with key informants were conducted to gather data. The analytical framework is rooted in the AIDDA concept, encompassing Attention, Interest, Desire, Decision, and Action. The findings reveal that the Surabaya PITI Institute adeptly implements the AIDDA concept in the context of persuasive communication. Beginning with capturing converts' attention through the introduction of the ta'aruf program by da'i, the program proceeds to generate interest by delivering engaging and relevant content. The da'i employs a gentle and persuasive language when imparting Quranic teachings and avoiding coercion. As a result, converts make informed decisions to embrace Islamic practices such as regular prayer, zakat, and fasting, signifying a meaningful behavioral shift towards adherence to Islamic principles. Consequently, converts integrate the teachings presented by the da'i, prioritizing Islamic doctrines derived from the Quran and Hadith while gradually distancing themselves from conflicting Chinese cultural practices. This research provides insights into the role of persuasive communication in guiding converts and offers implications for the development of effective Da'wah strategies and approaches.

Published: April 2024

Taha Abdurrahman, a contemporary maqasid figure, has different concepts and ideas from the Shatibi maqasid concept. The concept of maqasid Taha Abdurrahman also has a paradigm and classification of values that are different from the concept of maqasid Shatibi. This study aims to describe the paradigm of reform of maqasid values according to Taha Abdurrahman. In addition, this study also describes the classification of new maqasid values according to Taha Abdurrahman. This research uses a qualitative approach that explains and analyzes the concepts and ideas of maqasid al-shari'ah reform according to Taha Abdurrahman. This research uses a library method with the main data source of Taha Abdurrahman's work entitled Tajdid al-Manhaj fi Taqwim al-Turath, and Su’al al-Manhaj fi Ufuqi al-Ta’sisi Liunmudhaji Fikri Jadidi. The results of this study show that the paradigm of reform of maqasid values according to Taha Abdurrahman is based on the hadith of the Prophet “Innama Buitstu Liutamimma Makaarimal Akhlak” which is holistic in nature encompassing all levels of needs that are an integral part of Islamic law. The classification of new maqasid values according to Taha Abdurrahman is contained in the concept of “al-qiyam al-akhlaqiyyah” Include al-masalih al-hayawiyyah, al-masalih al-‘aqliyyah, and al-masalih al-ruhiyyah namely maqasid values  with dimensions  of materialism, rationalism, and spiritualism.   Taha Abdurrahman's classification of maqasid al-shari'ah revises the conception of the Shatibi maqasid.
Rethinking Islamic Feminist Thought on Reinterpreting the Qur'an: An Analysis of the Thoughts of Aminah Wadud, Fatima Mernissi, Asma Barlas, and Riffat Hassan

Published: April 2024

This article aims to revisit Islamic feminist thought on the reinterpretation of the Qur'an by analyzing the views of four major figures in the movement: Aminah Wadud, Fatima Mernissi, Asma Barlas, and Riffat Hassan. This study uses a critical text analysis approach to understand the arguments and interpretations they put forward in interpreting Qur'anic verses related to gender. Through an in-depth analysis of their work in articles, books, and papers of their views. In addition, the article explores the ways in which these Islamic feminists reconstruct an understanding of sacred texts, highlighting differences in approach and common themes in their interpretations. In addition, it evaluates the impact of their reinterpretations of the Qur'an on traditional views in Muslim societies and their implications in the context of social change and gender equality. When examining Islamic feminist views on the Qur'anic reinterpretation, it is important to thoroughly understand the cultural and linguistic context of Arabic. Misconceptions regarding the interpretations of classical Muslim intellectuals, which are often considered discriminatory against women, are often due to a lack of understanding of the cultural and linguistic context of Arabic. Therefore, it is important to pay attention to linguistic and cultural contexts when interpreting sacred texts. On the other hand, feminists should also note that interpretations of the Qur'an do not always result in interpretations that are in line with their principles of gender equality. The theoretical implication is that, in an effort to understand the verses of the Qur'an related to gender issues, it is important to consider the cultural context, language, and comprehensive interpretation. There is room for dialog and deeper understanding between feminist views and traditional interpretations, by taking an approach that combines an understanding of classical Arabic culture with the values of gender equality championed by feminists.

Published: April 2024

The article deals with the issues of ensuring the goals of criminal punishment through the implementation of certain means of correction of convicts, which are regulated by the penal enforcement legislation of the Russian Federation. The solution of certain tasks assigned to the criminal law is possible through the introduction of amendments to the legal regulation and practice of the use of basic means of correction of convicts. The author actualizes such a means of correcting convicts in the execution of a custodial sentence as vocational training. The analysis of the impact of the considered remedy on the subsequent re-socialization of persons who have served their sentences and the integration of these subjects into civil society is also carried out. The subject of the study is the norms of penal enforcement law regulating the maintenance of means of correction of convicts, as well as the practice of their application. The purpose of the study is to scientifically substantiate and update the priority means of correction of convicts. The current state of the use of means of correction of convicts can be characterized as an institution requiring certain changes. The necessity of strengthening the work of the administrations of institutions and bodies executing punishments within the framework of vocational training of convicts is argued.

The article examines the problems related to the legal regulation of incentive measures and their application in penitentiary practice. The legal incentives existing in the Russian penal enforcement legislation, represented by incentive and a number of other norms, are not a fully integrated and consistent system. Only certain criteria for assessing the personality and behavior of a person sentenced to imprisonment are fixed, there is no systematization of them, there is no unified approach to their formulation, they are mainly evaluative (or too general. As a result of the conducted research, the author came to the conclusion that it is necessary to expand the list and disclose the content of the criteria for the correction of convicts in order to ensure their uniform interpretation by the law enforcement officer. This will make it possible to use the measure of encouragement in which the convict will be most interested and the application of which will help correctional officers achieve maximum correctional and educational impact.

Published: April 2024

The article is devoted to the problems of realization of legal advantages within the framework of the legal status and legal status of persons sentenced to imprisonment. The author, based on the available scientific points of view, comes to the conclusion that it is necessary to fully incorporate legal advantages into the content of the legal status and legal status of convicts through normative legal consolidation. Proper regulatory regulation of legal advantages will help to minimize risks and negative consequences in ensuring the rights of convicts. Modern general scientific and special methods of cognition were used in the work: analysis, synthesis, historical and legal, structural and functional, normative and logical, complex. At the same time, the article reflects the author’s subjective position on this issue.

The article gives a positive assessment of the work of the team of authors on the preparation of the textbook «Penal Enforcement law of the Russian Federation and the Republic of Azerbaijan. The general part» edited by A. P. Skiba and M. G. Gumbatov. Special attention is paid to issues of high scientific interest and disclosed in the textbook on penal enforcement policy, the legal status of convicts, the list of institutions and bodies executing sentences and the powers of their employees, types of control over their activities (judicial, public, etc.), the introduction and implementation of various forms of probation in the Russian Federation and the Republic of Azerbaijan. The probable direction of further work in this area has also been determined: it is advisable to concretize a comparative analysis of the legislation of the Russian Federation and the Republic of Azerbaijan, including institutions of purely penological (means of correction, powers of employees of institutions and bodies executing punishments, etc.) and intersectoral (list of punishments and other criminal legal measures or types of early release from serving punishments) of a nature.
Accumulation of microcystins, bacterial community composition and mlrA gene abundance in shrimp culture ponds

Cyanobacteria blooms occur frequently in low-salinity shrimp culture ponds. To provide useful information about the potential harm and in situ biodegradation pathway of microcystins (MCs) in these ponds, we investigated accumulation of MCs in shrimp hepatopancreas and sediments, bacterial community composition and mlrA gene abundance in intestines and sediments in 11 Litopenaeus vannamei culture ponds from 9 farms in China. MCs (MC-LR, MC-RR and MC-YR) accumulated in shrimp hepatopancreas and sediments in each sampled pond. Higher bacterial richness and diversity were observed in sediments than in intestines. Two MC-degrading genera (Sphingobium and Roseomonas) were detected in the intestine bacterial community, and 3 MC-degrading genera (Sphingobium, Rhizobium and Acinetobacter) were detected in the sediment bacterial community. The mlrA gene was easier to detect and more abundant in shrimp intestines than in sediments. These results suggest that there was a potential MC hazard in shrimp culture ponds, and the biodegradation pathway in shrimp intestines seemed to be more dependent on the mlr pathway than that in the sediments.
Effects of Estradiol Benzoate and Progesterone on Superoxide Dismutase Activity in the Thymus of Rats

Published: April 2024

The activity of mitochondrial superoxide dismutase (MnSOD) and cytosol superoxide dismutase (CuZnSOD) was measured in corresponding subcellular fractions prepared from the thymi of intact and chronically gonadectomized (GX) rats of both sexes, as well as of GX male and female rats injected subcutaneously with a single dose of 5 mg estradiol benzoate (EB) and/or 2 mg progesterone (P). Animals were sacrificed 2 h or 24 h following hormone treatment. In the females, the activity of MnSOD in the thymus was stable during the estrous cycle and did not change after ovariectomy. Treatment of GX females with estradiol benzoate resulted 2 h later in a significant elevation of MnSOD activity, whereas 24 h later the activity returned back to control values. On the other hand, treatment of GX females with progesterone had no effect on the MnSOD activity. However, combined hormone treatment, in which EB injection preceded progesterone injection by one hour, enhanced the effect on MnSOD activity similar to that of estradiol benzoate alone. The activity of CuZnSOD in cycling rats was increased in proestrus, whereas removal of the ovaries kept the values at low diestrus and estrus levels. Contrary to MnSOD, CuZnSOD activity did not change after EB treatment of GX females, while progesterone increased the enzyme activity at 2 h and 24 h after hormone treatment. However, combined EB+P treatment proved to be ineffective. In the males, neither MnSOD nor CuZnSOD activity was affected by the removal of testes or by progesterone treatment of GX animals. Only EB injection to GX rats significantly increased CuZnSOD activity 24 h later.
