In 2021, the Government of the Russian Federation set the executive authorities the task of decarbonizing Russian industry and developing an action plan for the transition to carbon regulation and sequestration of carbon dioxide emissions. One of the directions of carbon dioxide sequestration is mineral carbonation. The idea of the work is to use mineral carbonation, as an alternative to natural mineral raw materials, slags from the combustion of solid non-combustible waste. The technology of carbon sequestration by mineral carbonation of technogenic raw materials is at the research stage, therefore it is necessary to assess the potential of using waste incinerators. To solve the tasks, the material composition of the slags of one of the incinerators was studied in detail. The possibility of slag enrichment with the production of copper-containing preconcentrate has been established. The content of minerals capable of participating in carbonation was determined, and the carbonation potential was estimated based on the calculated values. The requirements for man-made waste for their use as raw materials for carbonation are formulated. The factors that have a restraining effect on the introduction of mineral carbonation technologies are highlighted.

Metallurgy and engineering endeavours to develop and implement advanced technologies to save metal and create new metallic materials with improved characteristics. These scientific and technological activities include improvements to existing materials as well as the development of new materials by various methods. One such method is the creation of iron-based materials with a gradient of properties along the cross-section, obtained by locally modifying a given volume of the formed billet by filling the structure with heat-resistant, high-strength, dispersed phases. This paper describes the course and results of a number of experiments on the formation of a gradient of properties in steel castings of various compositions, and analyses the results of experiments on the creation of such materials.

Published: November 2023

In the present work, thin carbon films and nanofibers of different morphologies were obtained by magnetron sputtering on a modernized VUP-2 unit. Information of vibrational properties of carbon films and nanofilaments was obtained by Raman spectroscopy. Carbon nanofilaments were obtained in the G band region 1580-1595 cm-1, which is in good agreement with the known literature data. Apparently, the most fascinating results were achieved when steel-3 was used as a substrate. This is probably due to the presence of carbon in steel-3, which serves as a condensation center for the formation of carbon structures, including carbon tubes. The study of amorphous films and their applications in diverse industries constitutes a significant area of scientific research, and this article offers an overview of synthesis methods and potential material applications.

Authors: Ashrafova Yegana , Aida-zade Kamil
Published: November 2023

The optimization of parameters for concentrated sources that influence the operation of a dynamic network structure is the focus of this study. The network structure comprises numerous one-dimensional objects, each governed by a system of ordinary differential equations with nonlocal boundary conditions to describe their states. Sources affect individual points within these subobjects, as well as their connection points. The optimization process aims to determine the optimal locations and power levels of these sources, based on predefined target functionality criteria. We derive the necessary optimality conditions for the concentrated sources' parameters and present the results of numerical experiments using a test problem as an illustrative example.

Equilibrium state as a compromise in the struggle of opponents
Authors: Koshmanenko Volodymyr , Karatayeva Tetyana , Satur Oksana
Published: November 2023

Mathematical models describing the conflict interaction between alternative opponents are studied. It is assumed that the adversaries are indestructible, located in different regions of the resource space, and receive external support in their struggle with each other. The main questions concern the compromise states of equilibrium (a certain type of fixed points) of the associated dynamic conflict system. Namely, the existence of such states, their stability, and the dominant side in each region. It has been established that states of equilibrium compromise arise only in the presence of external influences (supports) necessarily for both opponents and only some of them are stable with non-trivial basins of attraction. It was also found that with insufficient external support, the dominant opponent in each of the regions can sharply lose its position.

Published: November 2023

We investigate the problems of noise reduction in navigation data supplied by an accelerometer and a gyroscope. The MPU-6050 sensor module, which is often a component of drone navigation systems, was used in the experiments. To smooth the data, the use of "simple averaging method" and "moving average method" is recommended. We show experimentally that the data smoothing methods reduce the errors by more than 10 times. It is also shown that the "simple averaging method" can reduce the hardware load by more than 10 times compared to other data processing methods.

Purpose: to make a semi-quantitative assessment of mudflow risk based on empirical data on mudflows and the consequences of their collapse, obtained during the work at the construction and reconstruction of the Lgovskoe – Grushevka – Sudak highway on the territory of the Republic of Crimea and to develop recommendations on state stabilization, based on the assessment results. Materials and methods. The initial data on mudflows are divided into three groups, for each a step-by-step calculation was performed and points were assigned. The criteria by which the assessment has been made: the level of mudflow hazard and the amount of damage, the dependence of the amount of damage on the protective structures’ state. Calculated indicators such as mudflow velocity, flow rate, etc. have also been determined. Each group is assigned a mudflow risk category based on the results of scoring, taking into account their significance. Results. According to the results of the study, the total score for the third group is 15.18, which corresponds to the second category of mudflow risk, which is characterized by a high probability of significant damage. For the first and second groups, the total score is 9.88 and 11.34, respectively, thus, both groups fall within the boundaries of the third category of mudflow hazard. Conclusions. A semi-quantitative assessment of mudflow risk allows identifying potentially dangerous areas, informing on the threat and taking measures for land protection in advance. In order to protect lands from the destructive power of mudflows within the boundaries of the basins of the third group, it is necessary to erect mudflow protection structures, namely: agroforestry-reclamation erosion protection structures, mudflow retention, mudflow passage, mudflow-preventing structures and other engineering protection facilities of the territory.

Purpose: to develop mechanisms for territory zoning according to demand for land drainage and the volume of substances leaching with drainage runoff and to identify the methods for reducing the pollution of drainage runoff. All calculations are made using the example of macrozonal zoning of drainage when growing strategically important crops: spring wheat and potatoes – using the example of the European part of Russia. Materials and methods. The justification for drainage was carried out using the bioclimatic method of V. V. Shabanov. A dimensional analysis technique and laboratory experiments on leaching soil monoliths for determining the main factors influencing the leaching of substances from soil were used. Results. A justification of reclamation measures (drainage) for regions and districts of the Russian Federation was carried out using the example of grains and potatoes. The main water protection measures reducing the polluting impact on water intakes from drainage runoff include: the creation of biological engineering structures; passive measures – precise reclamation aimed at managing the conditions for the drainage runoff formation, taking into account soil heterogeneity based on the zoning of drainage and the volume of nutrient leaching from drained lands. Conclusions. The European part of Russia has been zoned based on demand for drainage. A low degree of demand for land drainage when growing spring wheat was noted on approximately 40 % of the area and high degree was noted on 50 %. When growing potatoes, these areas account for 20 and 50 % of the area, respectively. The influence of factors on the drainage runoff formation and the volume of substance leaching was revealed. Water protection measures are proposed: construction of biological engineering structures and carrying out precise reclamation as a way to control the water regime of soils.
Reclamation complex in the Don River Basin and suggestions for its improving
Authors:   Russian Scientific Research Institute of Land Improvement Problems, Novocherkassk, Russian Federation, Voyevodinа Lidiya A.
Published: November 2023

Purpose: to analyze the presence and condition of water management systems (WMS) and hydraulic structures (HS), which are in federal ownership (FO) within the Don Basin District (DBD), and to develop proposals to improve the efficiency of WMS and HS functioning. Discussion. In the Don River Basin as of 01/01/2023, there were 11 % of the total number of water management systems in the Russian Federation in the FO, the predominant type was irrigation. The number of hydraulic structures was 6 % of the total number of federal hydraulic structures in the Russian Federation. An insignificant presence of hydraulic structures was noted (about 1 % of the number of hydraulic structures in the DBD), corresponding to the design technical condition, 71 % required routine repairs, about 5 % required major repairs, approximately the same number needed reconstruction, 14 % required disposal. The predominant part of the hydraulic structures was characterized by wear of more than 75 %. To overcome the crisis situation in the reclamation industry, including in the Don river basin, it is proposed to consider a separate reclamation system (RS) and the organization managing it (OMS) as the main management unit. It is advisable for the OMS to be state-owned and have access to any part of the RS. The OMS should be involved in the process of cultivating crops and be interested in high yields and of agricultural products quality. One of the elements of the interest mechanism should be the data on harvesting from reclaimed lands, similar to that provided for by federal statistical observation in the form 29-СХ (chalk); it is advisable to submit this information also to the OMS. To improve the RS management process, geoinformation maps are being developed, the first stage of development was the “Instructions for forming and providing spatial data about RS and HS”. Conclusions. The practical implementation of the above-mentioned proposals can increase the efficiency of organizations operating RS and contribute to the rational use of water resources in the Don Basin.

This study investigates the tear strength properties of a cotton-Lyocell blend siro spun fabric. Lyocell fibre production follows sustainable practices with a closed-loop system and renewable resources, requiring less energy and water. Furthermore, Lyocell is a biodegradable fibre, ensuring its environmentally friendly decomposition. Similarly, cotton offers durability, washability and biodegradability, making it an eco-conscious fabric alternative. Woven fabrics were created using cotton-Lyocell blend siro spun yarns with varying twist multipliers and thread densities in plain, twill and satin weaves. The tear strength of these fabrics was measured and regression analysis was conducted to investigate the impact of different parameters. The results demonstrate that twist multiplier, warp density and weft density significantly affect the tear strength of all fabric types. Furthermore, a comparison was made between the tear strength of the cotton-Lyocell siro spun fabrics and conventional ring-spun cotton fabrics and found that cotton-lyocell siro spun fabrics offer better strength properties compared to conventional ring-spun cotton fabrics. The findings of this study provide valuable insights into fabric strength factors, contributing to future research in textile development for enhanced durability and sustainability.
Oświadczenie woli w celu wspólnego pożycia w małżeństwie w epoce ponowoczesnej
Authors: Stadniczeńko Stanisław
Published: November 2023

Autor wskazuje, że czasy współczesne, czyli tak zwana era ponowoczesna charakteryzuje się wyraźnym wzrostem niepewności wzoru zachowania, poczuciem chwiejności między dobrem i złem, poczuciem daremności wysiłków w opanowaniu chaosu. Osoba uwikłana coraz silniej w skomplikowany układ powiązań społecznych, coraz silniej od tych powiązań uzależniona, coraz częściej będzie narażona na to, że jej jakiekolwiek przejawy autonomii z jej strony będą zawsze miały pewien refleks na sytuację innych uczestników. W sieci władzy jakiej się poddała sprawuje nad nią władzę wpływając na jej umysł przede wszystkim, choć nie wyłącznie, za pomocą multimedialnych sieci komunikacji masowej. To prezentowane pojęcia odpowiednio dobrane i zhierarchizowane nie tylko stanowią niezbędny środek wyrazu, lecz warunkują wstępnie, stojący u podstaw światopoglądu tak zwany obraz świata. Uzależnienie od sieci wyklucza swobodę myśli, ocen, opinii, nie pozwalając na weryfikację informacji uzyskanych w sieci. Technologia zmierza więc do coraz większego kontrolowania ludzkich myśli, poglądów, postaw, ocen wpływając na ich urzeczywistnianie, tworząc model nowego człowieka. To one kształtują prywatne światopoglądy poszczególnych ludzi. Tak więc źródłem władzy jest konstruowanie znaczeń w ludzkich umysłach. Sposób myślenia jednostkowych osób decyduje o losie instytucji, norm i wartości wokół których zorganizowane są społeczeństwa. Zauważyć należy, iż emocje zdominowały rozum a nawet intelekt. Społeczeństwo usieciowione w tym jednostkowe osoby nie potrafią już składać świadomego i swobodnego oświadczenia woli, bowiem podlegają i ulegają wpływom świata oglądu, który prezentowany jest przez sieć. Składa więc oświadczenie woli pod wpływem błędu co do otaczającej go rzeczywistości. W życiu społecznym widoczna jest atrofia woli, a wraz z nią odpowiedzialność za siebie, za innych, która może być ujmowana jako pochodna socjalizacji społeczeństwa ponowoczesnego, m.in. narcyzm, pogoń za ciągłą stymulacją, konsumpcja, kult młodzieńczej niedojrzałości, hedonizm, wydłużający się okres zależności dzieci od nadopiekuńczych rodziców, która w konsekwencji prowadzi do kształtowania u nich osobowości niezdolnych do wysiłku, skupienia, trudów i wyrzeczeń, w celu realizacji aktów woli. Reguły moralne utraciły właściwy swój smak i sens, dobro utożsamiane jest z korzyścią a normy moralne z zasadami działania, których przestrzeganie przynosi jakiś pożytek. Ujawnia się poważny kryzys relacji międzyludzkich, relacje często są pozbawione pozytywnych emocji, związków uczuciowych, więzi, konsekwencji i odpowiedzialności. Temu zjawisku należy położyć kres, ale najpierw trzeba je dobrze zrozumieć.
Development of Competences of the Primate of Poland and the President of the Polish Bishops’ Conference
Authors: Banduła Paweł
Published: November 2023

The rights and privileges of the primates of Poland were considerable. Polish primates crowned Polish kings, blessed royal marriages, and presided over the funeral rites of Polish kings. They were the first senators of the Kingdom, and in the king’s absence they acted as his governor and interrex. They had the right to convene the Sejm, Senate councils and order general mobilisation; they were members of governmental bodies, had precedence before princes and dukes, sat before cardinals, had a princely title and a coat of arms, and wore purple robes. A turning point for the hierarchy came with the new legislation of the universal Church. Canon 438 of the 1983 Code of Canon Law expressly regulates that, apart from the prerogative of honour, the primate no longer has any power of governance, unless otherwise stated for some of them by apostolic privilege or approved custom. Canon 452 prescribes the election of the president of the bishops’ conference. Currently, Primate of Poland is an honorary title for the metropolitan archbishops of Gniezno. The privileges inherent in the functions of the primate are precedence during liturgical celebrations, a permanent place in the Permanent Council of the Polish Bishops’ Conference, the right to wear purple and to have 30 tassels in his coat of arms.

The adoption of such a solution results from the fact that the premises included in the provision refer to the prescriptive or prohibitory laws, which, in the aspect of nullity of the act, are less radical than the invalidating or incapacitating laws (Canon 10), to which the legislator referred in Canon 15 § 1. Moreover, the analysis of the regulations outside the first book of the Code of Canon Law as well as the doctrinal heritage demonstrates that, in relation to the area defined in Canon 15 § 2, in the canonical legal order there still exist prior principles resulting from the systemic assumptions and the general theory of a legal act resulting in the fact that, in certain circumstances, the general rules are not valid.
It is claimed that the introduction of the presumption iuris tantum in the second part of the sentence of Canon 15 § 2 was due to the fact that a non-notorious fact of another is not characterized by such obviousness as one’s own or another’s notorious fact.

Given the steady increase in the number of patients with diabetes mellitus, the need for sufficient and high-quality glucose monitoring forces researchers worldwide to create and study more and more new methods of managing blood sugar. Currently, continuous glucose monitoring demonstrates the best results. However, the use of modern technologies is not always possible in clinical practice. One of the currently discussed methods is the structured 7-point blood glucose monitoring. Such a self-care option contributes to the greater adherence of patients to treatment, improvement of their life quality, and risk reduction of diabetes acute complications. This article presents an overview of foreign studies devoted to assessing the possibilities of the structured 7-point blood glucose monitoring in practice. We also presented our own data demonstrating the benefits of using glucose meters with a mobile application as part of a modern approach to 7-point blood glucose monitoring for 14 days. It was aimed at effectively reducing the glycated hemoglobin level in patients with type 1 and type 2 diabetes mellitus. KEYWORDS: diabetes mellitus, glucose monitoring, hypoglycemia, hyperglycemia, acute complications of diabetes mellitus, mobile application.

Cushing's disease is a severe neuroendocrine disorder caused by excessive release of adrenocorticotropic hormone by pituitary tumor. The rate is 39.1 per 1 million and the incidence is 1.2–2.4 per 1 million. Typical symptoms include rapid weight gain associated with muscle weakness, hypertension, diabetes, and osteoporosis. The key diagnostic tool is brain MRI after laboratory confirmation of a diagnosis of hypercortisolemia. The key treatment is transsphenoidal adenomectomy, which provides remission in 65–90% of patients. This paper describes the severe course of Cushing's disease in a male patient, which has long remained undiagnosed. Diagnostic search steps, differential diagnostic difficulties, and follow-up results (including inferior petrosal sinus sampling) are discussed. A multidisciplinary approach and teamwork ensure timely diagnosis, prevent complications of Cushing's disease, and improve prognosis and quality of life.

The novel Abemaciclib derivative WXJ-8 may be a promising anti-tumour drug; however, its mechanism of action and clinical value need to be further verified in research. Cell cycle regulating systems are critical in parthenogenesis and progression. Because of its involvement in regulating cell cycle checkpoints, the CDK4/6-CyclinD1-Rb-E2F1 signalling pathway has been proposed as a possible therapeutic target for breast cancer. As a result, WXJ-8, a new and highly specific CDK4/6 inhibitor, was developed and synthesized in this investigation. The activity of WXJ-8 against breast cancer cells in vitro was detected by MTT method. The main subjects were MDA-MB-231 and MCF-7 cells. Plate cloning, wound healing, invasion and adhesion experiments revealed that WXJ-8 had strong anti-proliferation, migration, invasion, and adhesion effects on breast cancer cells. Protein blotting revealed significant down regulation of CDK4, CDK6, p-Rb, E2F1 and other cell cycle factors in the CDK4/6-CyclinD1-Rb-E2F1 pathway, as well as activation of Bcl-2, Caspase-3, and Cleaved Caspase-3 apoptotic factor expression, resulting in MDA-MB-231 cell cycle arrest and apoptosis. Finally, our research implies that WXJ-8 might be a potential anti-triple-negative breast cancer medication candidate.

The existence of Adat in Aceh is getting stronger after the MoU between the Indonesian government and the Free Aceh Movement. However, it cannot be denied that customary disputes continue to occur. Lecturers as academics are required to be involved in the customary settlement process because this is a form of lecturer service to the community. This paper aims to look further at the involvement of PTKIN lecturers in Aceh in the customary dispute resolution process. This research resulted from an empirical study using a sociological approach. The sociological approach looks at how the activities of the Acehnese indigenous people contribute to resolving customer disputes. This study focuses on two PTKIN consisting of lecturers at UIN Ar-Raniry and IAIN Lhokseumawe. Data sources were obtained from interviews and observations; data analysis was carried out by means of data reduction obtained from the interviewer, and then analysis was carried out. The results of this study indicate that practically, law lecturers, with their scientific discipline, have contributed to the resolution of customary disputes. The law lecturer at PTKIN has carried out several stages of customary dispute resolution, starting from examining the problem, carrying out mediation, and reviewing legal norms that are used as a reference in dispute resolution. The strategy for resolving disputes is carried out by classifying the problem and bringing it closer to the legal aspect so as to produce a balanced solution both in terms of aspects of religious law and state law. Obstacles and problems that occur are related to the lack of agreement between the parties regarding customary decisions, so the parties choose the path of litigation (court). The litigation route is the last alternative when an agreement cannot be reached through a customary decision.

Background and Objective One of the types of cognitive impairments in patients with multiple sclerosis (MS) is verbal fluency. Clinical characteristics affect verbal fluency. This study investigates the relationship between verbal fluency and some clinical characteristics in patients with MS. Materials & Methods This cross-sectional descriptive study was performed on 71 patients with MS in Rofideh Rehabilitation Hospital. Patients were selected by convenience non-probability sampling method. The study tool included the Pittsburgh sleep quality questionnaire, fatigue severity scale, depression inventory-fast screen, and controlled oral word association test. The collected data were analyzed in SPSS software, version 18. The linear regression model was fitted to evaluate the effect of independent variables on verbal fluency. Results The study included 67.6% of female and 32.4% of male patients. The average age of the patients was 43.9±35.54 years and the average duration of the disease was 13.83±5.62 years. The results showed that some clinical characteristics including fatigue, disease type, first symptom, and sleep status have a significant relationship with the verbal fluency score of patients with MS (P<0.05). No significant relationship was observed between expanded disability status score, depression, and duration of disease with verbal fluency in patients with MS. Conclusion The results showed that patients with the progressive type of the disease and patients whose onset of the disease was reported with visual symptoms had a weaker performance in verbal fluency than other participants. This issue can be considered in the early stages of disease diagnosis.

In the last century، more than 2. 6 billion people in the world have been affected by natural disasters، such as earthquakes، floods، storms، landslides، and climate changes. The delivery of bad news after natural disasters is one of the responsibilities of therapists. The bad news refers to any information that cause negative changes in a patient's view of the future. It is not possible to use the same protocol to deliver bad news for all situations. It is not possible to use the same protocol to deliver bad news for all situations. It is necessary to localize or develop the Persian version of the SPIKES protocol to break bad news during natural disasters in Iran، and it is recommended to be included in the emergency response plan. Such protocol can be used in line with the activity and evaluation of the validity criterion of "breaking bad news to the patient/legal guardian by the ethical principles and predetermined methods"، and also for the use of pre-hospital and hospital cares.
