The conversion of natural ecosystems into agricultural or urban areas can alter geomorphological processes, particularly in landslide-prone regions. Landslides in such areas can be triggered by natural events like heavy rainfall or earthquakes, as well as human activities such as deforestation and unplanned urbanization. Their impacts can be severe, resulting in significant socio-economic damage. Uvira Territory, in the western part of the East African Rift Valley, frequently experiences these events. It is located between the Ruzizi Plain to the east and the Mitumba Mountains to the west, with diverse geology comprising precambrian formations and quaternary sediments. The topography has a stepped relief with altitudes ranging from 770 to 3250 meters. The climate is tropical and humid, with a rainy season from September to May and a dry season from June to August. The area features coastal plains and mountain slopes, with many waterways flowing into Lake Tanganyika or the Ruzizi River. Detailed studies on landslide susceptibility mapping in this area are limited. This study aimed to map landslide susceptibility in the Kiliba River catchment to assist policymakers in land management. It used Google Earth images, GPS surveys, and field observations, applying a Frequency Ratio (FR) model that considered seven geo-environmental factors: slope, aspect, elevation, distance to watercourses, topographic wetness index, vegetation cover, and land use/landcover. The inventory identified 106 landslides in the study area, with densities of up to 11.25 landslides per km². Key factors in predicting landslide susceptibility were slope, elevation, and vegetation cover. The prediction model had an accuracy rate of 72.2%. The study shows that regions at medium elevation with steep slopes and low vegetation cover are mostly at risk for landslides. These findings are key for land management and disaster prevention. Future studies should consider more factors and a broader geographic range to enhance risk management
A Subject Review on Application of Analytical Chemistry in the Mitochondrial Medicine
Authors: Jasim M. S. Jamur
Published: June 2024

Understanding energy metabolism and intracellular energy transmission requires knowledge of the function and structure of the mitochondria. Issues with mitochondrial morphology, structure, and function are the most prevalent symptoms. They can damage organs such as the heart, brain, and muscle due to a variety of factors, such as oxidative damage, incorrect metabolism of energy, or genetic conditions. The control of cell metabolism and physiology depends on functional connections between mitochondrial and biological surroundings. Therefore, it is essential to research mitochondria in situ or in vivo without isolating them from their surrounding biological environment. Finding and spotting abnormal alterations in mitochondria is the primary research technique for understanding mitochondrial illnesses. The purpose of this review is to collect original studies and papers describing a variety of analytical chemistry tasks carried out in mitochondria. Analytical chemistry is essential to the biological and medical sciences. Several analytical methods have been used in this field, such as chromatographic, spectroscopic, spectrophotometric, electrochemical analysis, and electrospray ionization mass spectrometry. While spectroscopic techniques in particular have yielded important information in certain cases, the nature of these techniques nevertheless limits the information that can be collected. Mass spectrometry may, however, produce incredibly detailed datasets.

Nanotechnology deals with the application of atoms, molecules, or macromolecules with sizes ranging from 1 to 100 nm to create and utilize materials with distinct and novel characteristics. Nanotechnology has gained popularity over the past few decades and is now widely regarded as a revolutionary technology in the food industry. Various nanoencapsulation techniques have been spawned by the boom in interest in nanotechnology and its application in food products. One of the most exciting encapsulating and delivering methods in the food sector is nanoemulsion. 
A nanoemulsion is a mixture of two immiscible liquids and a surfactant that takes the form of tiny droplets less than 200 nm in size. Delivery methods based on nanoemulsions increase the bioavailability of the bioactive substances that are encapsulated and improve food stability. Since nanoemulsions are thermodynamically unstable, they need a certain amount of energy to create them. The preparation technique chosen determines the creation and permanence of nanoemulsions.
This review provides an overview of nanoemulsion terminology and formulation; and also addresses various approaches for producing nanoemulsions, including both high- and low-energy techniques. In addition, the applications of nanoemulsions in the food industry.

Microwave Pyrolysis of Automotive Polypropylene Based on a Microwave Atmosphere Tube Furnace
Authors: Pan Guanghao , Zhang Hongshen , Chen Tianyi
Published: July 2024

Plastics have light weight and excellent performance, which are widely used in all kinds of automobiles. Polypropylene (PP) and its reinforcing materials are used in automotive components, where the surfaces of bumpers and fenders are coated with paint. Traditional recycling can frequently generate various pollutants, such as paint sludge. Microwave pyrolysis is a more environmentally friendly pyrolysis method with a higher heating coefficient than traditional electric pyrolysis. This study first explores the elemental composition of two types of automotive PP plastics and uses thermo-gravimetric analysis and the Kissinger-Akahira-Sunose method to preliminarily calculate the activation energy of automotive PP. The calculation results show that the activation energy of PP containing paint ranges from 189.145 kJ/mol- 199.513 kJ/mol, with an average value of 193.903 kJ/mol. The activation energy of PP without paint is between 215.506 kJ/mol-265.794 kJ/mol, with an average value of 242.425kJ/mol. Then, pyrolysis experiments on PP for vehicles without paint are conducted using a microwave atmosphere tube furnace at different temperatures and microwave powers. The experimental results showed that, when the pyrolysis temperature increased from 500oC to 620 oC, the total proportion of gas products rose from 0.75 wt.% to 4.81 wt.%, and the content of alkanes in the liquid products improved from 26.21 wt.% to 34.37 wt.%; when the microwave power increased from 900 W to 1100 W, the gas product rose to 20.77 wt.%, and the content of aromatic compounds in the liquid product improved to 17.78 wt.%. In addition, the pyrolysis experiment of automotive PP containing paint showed that paint had a relatively minor effect on the pyrolysis products of automotive PP. This study shows that using microwave pyrolysis to treat automotive PP and PP with paint is feasible, which provides a reference for the clean treatment of automotive polymers.

The main findings of the study are as follows First, in the meta-analysis of studies by time period, the keywords 'Jeonse', 'Jeonse price', and 'apartment' appeared in all periods, and the keyword 'long-term Jeonse housing' began to appear after 2009. Based on this, it was found that the main topics of interest to researchers expanded to studies centered on rental issues such as 'Jeonse rate' and 'offset', and recently reached major social issues of Jeonse housing such as 'Jeonse deposit', 'Jeonse fraud', and 'reverse Jeonse'. In addition, the topics classified through topic modeling were named as 10 in total, and the 10 topics were classified into 3 research topic groups:“Jeonse market and status in Seoul,” “Jeonse-related laws and systems,” and “Jeonse price and market analysis.” Based on the above analysis results, we can confirm that the trend of Jeonse research is expanding to price analysis, market status analysis, and law and system analysis, and finally, it is meaningful to understand the overall research trend by focusing in detail on the central word of “real estate Jeonse research” and to present future research topics in a way to understand social issues.
Prioritization of Soviet-Finnish negotiations of 1938-1939.
Authors: Chernetsov Boris
Published: June 2024

This article examines the complex of Soviet-Finnish negotiations through the lens of the issue of priority of Soviet demands in the period of the autumn negotiations of 1939. The negotiation process between the USSR and Finland, concerning the relations between the two states against the background of Germany's aggressive policy, began not in the fall of 1939, but a year and a half earlier - in the spring of 1938. The points of the Soviet demands voiced by the Soviet side during the negotiation process were changed and adjusted. Moreover, in comparison with the Soviet proposals of 1938, there were new points that had not appeared before. The study of the reasons for the changing rhetoric in the negotiation process between the USSR and Finland will help to understand the nature of the breakdown of the negotiations in the fall of 1939.
The problem of the article is the question of the correctness or incorrectness of the thesis about the priority of the goal of moving the land border on the Karelian Isthmus away from Leningrad during the negotiations between the Soviet Union and Finland in 1938-1939. This thesis has not been questioned in domestic historiography, apparently because only the Soviet demands of 1939 were taken as a basis and less importance was attached to the proposals put forward by the Soviet side during the negotiations of 1938 and the spring of 1939. The confirmation or refutation of the thesis about the priority of the clause in the text of the memorandum on the movement of the land frontier on the Karelian Isthmus should be the outcome of this study.

Dalam rangka meningkatkan pendapatan masyarakat dan kampung, diperlukan sarana perekonomian melalui pasar kampong sebagai pusat interaksi sosial masyarakat perkampungan. bentuk interaksi sosial di Kecamatan Baiturahman juga hadir pasar kampong, baik yang yang direncanakan secara permanen maupun pasar dadakan. Kecamatan Baiturahman memiliki beberapa pasar yang bersifat permanen yaitu; pasar pagi Setui, Pasar Mini Kampong Baro dan pasar pagi Peniti. Ketiga pasar inilah yang menjadi objek pengamatan. Objek pengamatan difokuskan pada pasar ikan dengan mengamati sistem pengolahan air limbah pada ketiga pasar ikan tersebut. Metode yang dilakukan melalui pengamatan dan wawancara terhadap pelaku pasar baik pengelola, pedagang dan pembeli. Berdasarkan Identifikasi Sistem Pengolahan Limbah pada ketiga Pasar Ikan di Kecamatan Baiturrahman ini, dapat disimpulkan bahwa: Terdapat dua jenis limbah di pasar ikan, yaitu limbah padat dan limbah cair. Limbah padat berupa bagian ikan yang tidak dipakai seperti: tulang, kepala, ingsang, kulit, usus, perut dan sisik. Limbah cair berupa darah ikan serta air dari hasil penyiraman dan pembersihan ikan. Sistem pengolahan limbah pada masing-masing pasar berbeda-beda. Sistem pengolahan limbah pada Pasar setui dilakukan dengan memisahkan limbah padat dan limbah cair. Limbah padat diolah menjadi kompos dan limbah cair dialirkan melalui bak kontrol ke bak penguraian kemudian ke bak pengolah dan terakhir dibuang ke drainase. Pada Pasar Gemilang Kampung Baru dan Pasar Pagi Peniti, pengaliran limbah cair langsung dialirkan ke saluran yang ada di lingkungan tanpa pengontrolan jenis limbah, sedangkan limbah padat langsung dibuang ke tempat pembuangan sampah. Proses pembuangan limbah cair pada pasar pagi peniti dilakukan melalui proses penyaringan namun tidak melalui proses pengolahan dengan sistem Instalasi Pengolahan Air Limbah (IPAL). Kondisi ketiga pasar tersebut sudah tersedia drainase khusus untuk mengalirkan limbah cair ke luar bangunan pasar. Namun proses pengolahan limbah baik padat maupun cair hanya dilakukan oleh Pasar Pagi Setui.
Metering of the Oil and Natural Gas System Emissions using Aerial Site Measurement
Authors: Agbi Best Eromosele
Published: June 2024

Aerial methane surveys of oil and natural gas systems have discovered large emissions, which are missing or vastly undercounted in official estimates. We integrate approximately one million aerial site measurements into regional emissions inventories, employing empirically grounded emissions simulations to estimate small emissions. We infer emissions inventories for six regions in the United States comprising 52% of onshore oil and 29% of gas production over fifteen aerial campaigns. Total estimated emissions range from 9.63% [9.03%, 10.37%] of natural gas production, roughly nine times the US government estimate, to 0.75% [0.65%, 0.85%] in a high-productivity gas-rich region. Aerially measured emissions at 0.05%-1.44% of well sites contribute 50%-81% of total emissions in twelve of fifteen campaigns. The social cost of methane emissions from these measured regions is roughly $9.4 billion per year, in addition to roughly $1 billion in lost sales. This highlights the importance of incorporating comprehensive remote sensing surveys into emissions inventories and efforts to benchmark and reduce methane emissions.
Development of Process Safety Cumulative Risk Assessment in Niger-Delta Region, Nigeria
Authors: Popoola Mobolaji Adekunle
Published: June 2024

One of the key challenges in preventing major process safety accidents in an operating plant is the lack of an integrated system/model that brings together the risks posed by the deficiencies / deviations on the safety critical barriers, for operational decision making. Based on this context, an exploratory study was undertaken to develop a model/framework for visualizing the accumulation of process safety risks arising from safety critical barriers impairments in petroleum facilities in Niger-Delta Nigeria. The results indicate that the process safety cumulative risk assessment framework/model offers a transparent mechanism for assessing and visualizing the cumulative risks arising from the barrier impairment problems. For the facility in the first case study, 3.2% of the total number of safety-critical barriers was deviated and the model revealed risk accumulation in the gas compression functional location. For the facility in the second case study, 1.7% of the total number of safety-critical barriers was deviated and the model revealed risk accumulation in the gas dehydration functional location. When applied properly, the model/framework will reduce the risk of major accident in petroleum facilities by (a) aiding better management of safety critical barriers deviations through improved risks visual and (b) eliminate variability in human interpretation of process safety risk levels. One improvement area identified in the model/framework is the need for a web-based software for automation of barrier impairment data collection and real-time visualization of the cumulative risk picture.

Methods and information system for automated selection of a decision-maker
Authors: Afanasev Mikhail A. ,   Plekhanov Russian University of Economics
Published: July 2024

The effectiveness of management activities is largely determined by the degree of reasonableness and efficiency of selecting a decision-maker and delegating the necessary powers to him. To solve this problem, it is advisable to use mathematical methods and information technologies that ensure the specified selection in an automated mode. This approach involves the creation of a DSS using unpopulated decision-making technologies. This allows you to identify employees or groups of employees who are most suitable for the implementation of managerial functions in terms of certain quality indicators. The use of unpopulated decision-making technologies in the interests of economic entities makes it possible to reduce the time and cost of their adoption by automating the transit management level. The purpose of the study considered in this article is to solve the problem of organizing the effective selection of a decision maker (DPR), or a group of people, as well as transferring the task to be performed automatically. To achieve this goal, the mathematical modeling of the LPR selection algorithm (LPR group) was carried out by performing operations on sets containing significant indicators and solving a mathematical programming problem. The proposed mathematical apparatus makes it possible to create a subsystem of the DSS responsible for the selection of a DSS (group of DSS) capable of making a high-quality management decision under given constraints, and transferring tasks to it for execution. The specified restrictions contain the type of task to be solved, the possibility of its implementation with the help of unpopulated decision-making technologies, competence limitations of LPR (groups of LPR), time constraints. The DSS subsystem, created on the basis of the proposed mathematical apparatus containing the task of optimizing the selection of LPR (LPR group) according to the cost criterion, makes it possible to minimize the cost of decision-making.

Authors: Чалова Л.Р. , Локшин В.Н. , Киян В.С. , Кинжибаев А.А. , Турдалиева Б.С.
Published: July 2024

Актуальность: Использование донорской спермы в программах вспомогательных репродуктивных технологий (ВРТ) в последнее время набирает большую актуальность в связи с новыми социальными вызовами. Казахстан не стал исключением, и многие клиники на практике широко используют мужской донорский материал. Остается открытым вопрос отношения к использованию донорской спермы различных социологических групп, в том числе самих медицинских работников. Нет общего понимания, какими правилами должны регулироваться процедуры с использованием донорского материала, истинной цели доноров и качества предоставляемого биологического материала.
Цель исследования – определение актуальности использования донорской спермы (ДС) в программах ВРТ с позиции медицинских работников в Республике Казахстан, важность ведения учета за использованием ДС.
Материалы и методы: Анализ и сбор данных был проведен методом анонимного онлайн опроса Google Формы среди медицинских работников клиник ВРТ Казахстана. В опросе приняли участие 69 респондентов. Опрос проводился на протяжении двух месяцев, февраль-март 2023 года. Статистическая обработка исходно полученных показателей проведена с применением программы описательной статистики пакета компьютерных программ «Statistica 8.0» (StatSoft, Россия). Для сравнения категориальных переменных использован Z-критерий, хи квадрат. Достоверность различий сравниваемых параметров определяли начиная со значения р<0,05. Качественные переменные описаны абсолютными (n) и относительными (%) значениями с указанием доверительного интервала (ДИ).
Результаты: Результаты проведенного опроса показали, что большинство респондентов, непосредственно выполняющих программы ВРТ являются специалистами-экспертами, которые работают в данной сфере более 10 лет. По мнению 80,7% респондентов альтруизм не является мотивирующим фактором для участия доноров гамет в программах ВРТ и большинство доноров преследуют конкретную материальную цель. Финансовая мотивация может быть причиной недостоверной или неполноценной информации, очень важной для реципиентов. Несмотря на это большинство медицинских работников, связанных со сферой репродуктивной медицины, высказались в пользу использования донорского материала, а также объективного контроля, программ с использованием донорских гамет.
Заключение: Готовность и согласие специалистов в области ВРТ к введению учета и контроля за использованием донорского материала послужило основанием для инициирования процесса создания единого учетного электронного регистра доноров половых гамет в стране.

Актуальность: Депрессия после родов является распространенным и серьезным заболеванием, влияющим на качество жизни женщин и их способность к адаптации, к новой роли матери. Послеродовый период считается временем повышенного риска развития депрессии из-за физиологических, психологических и социальных изменений, сопровождающих беременность, роды и ранний послеродовый период. Понимание взаимосвязи между методом родоразрешения и развитием послеродовой депрессии имеет большое значение для разработки эффективных стратегий профилактики и лечения этого расстройства, а также для улучшения здоровья и благополучия матерей и их детей.
Цель исследования – определение связи между методом родоразрешения и послеродовой депрессией.
Материалы и методы: Обзор литературы включает анализ зарубежных научных публикаций научных электронных баз, данных Elsevier, PubMed, Web of Science, Google Scholar, а также результатов исследований, представленных в отечественных изданиях. Критериями для включения в этот обзор были: исследования, содержащие данные о послеродовой депрессии, у женщин с различными видами родоразрешений на английском и русском языках за последние 10 лет (1 января 2013 года – 31 декабря 2023 года).
Результаты: Физиологические роды отмечены низким риском развития послеродовой депрессии, однако развитие травм усиливает болевой симптом, соответственно, повышает риск депрессии. Частота родовозбуждений и случаев послеродовой депрессии имеют обратную корреляцию. Установлено, что введение эпидуральной анестезии снижает вероятность формирования послеродовой депрессии. Кесарево сечение, в особенности экстренное, как процесс с развитием болевого симптома, кровопотерей, ограничением подвижности является фактором риска послеродовой депрессии.
Заключение: Исходя из изученных материалов, следует, что проблема депрессивных состояний в послеродовом периоде у женщин значительна, к которой необходимо привлечь внимание для улучшения качества оказания профессиональной медицинской помощи женщинам и их родившимся детям, в результате это позволит снизить младенческую заболеваемость и смертность.

The sample, composed of 74 young people from the Guillermo Mensi Educational Unit in Cuenca, Ecuador, was intentionally chosen. During data collection, A survey was administered to educators to investigate their use of social-emotional tools, and two questionnaires, the TMMS-24 and the SDQ-Cas, were applied to students to evaluate their emotions, skills, and emotional difficulties. The results reveal that teachers recognize the importance of training in social-emotional skills. However, significant deficiencies were identified in the emotional awareness of adolescents, who also experienced emotional difficulties, behavioral problems, hyperactivity, and challenges in their interpersonal relationships. Despite these findings, positive attitudes toward socialization, empathy, and support stood out among students. The need to train teachers and implement effective socio-emotional education programs is emphasized to improve students’ quality of life and prepare them to face emotional and social challenges in their personal and academic endeavors.

This paper presents aspects related to the creation of an automatic classifier designed to evaluate and categorize the level of sexism present in the lyrics of songs of the urban music genre. The classification system assigns lyrics to three different categories: "A", indicating content suitable for audiences of all ages; "B", indicating content requiring adult supervision; and "C", representing adult-oriented material. The classifier was implemented in Python by applying the following algorithms: Naïve Bayes, nearest neighbours, decision tree, support vector machine and logistic regression. For the model training process, a dataset composed of 479 observations was created, divided into 75% for training and 25% for testing. The training dataset included both expressions with sexist connotations and those without. The classifier that achieved the highest degree of accuracy was the model based on the logistic regression algorithm with 77% accuracy. In order to facilitate the exploitation of the classifier in production environments, the model was integrated with a graphical user interface that facilitates the usability of the system for potential beneficiaries.

Implementing Energy Storage Systems (ESS) is increasingly significant in power electrical systems. This is attributed to their ability to store surplus electricity generated by renewable energy sources such as wind and solar, contributing to the balance between generation and demand. Literature studies indicate that this practice enhances network stability and diminishes the need for expensive redesigns in infrastructure. This paper presents an exhaustive experimentation-based study of the dynamic response provided by three energy storage system technologies: supercapacitors, Lithium-Ion batteries, and Vanadium redox flow batteries, technologies with significant academic, research, and industrial interests nowadays. The objective of this research is the experimental evaluation of the performance of such technologies in real electrical system operations, focusing on determining the efficiency of charge and discharge, as well as the tracking of active and reactive power achieved through the associated grid interface. The experimental tests performed in a microgrid laboratory show these technologies’ advantages and limitations in different grid-integration applications, with the Lithium-Ion battery-based ESS demonstrating the highest efficiency and faster power response. The results achieved and reported in the article can serve as an essential input for researchers and technology developers to feed their models with more precise parameters and data that might provide results closer to the actual behaviour of the studied prototypes. The methodological framework used in this research is descriptive, experimental, and quantitative.

The study addresses gender disparities in digital skills among computer science students at the Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López. Using a descriptive quantitative approach and stratified sampling, 212 students were selected for the study. A questionnaire validated by another research work and adapted to the needs of the study was used, including sections on artificial intelligence and ChatGPT, to assess basic and advanced digital skills. Data were collected through Google Forms, and analyzed with statistical software, using descriptive and inferential statistics, including t-tests and Mann-Whitney U tests. The descriptive analysis showed a predominance of male participation, a trend towards the use of mobile devices, and limited formal technological training. Significant gender-based differences were noted in programming and AI use, with pronounced disparities in interactions with ChatGPT and understanding of prompts, indicating gender variations in the perception and use of technology. The study concludes that there are evident gender disparities in areas such as prompt comprehension and the academic use of ChatGPT, aligning with previous studies on gender gaps in technological education. It suggests the need for educational strategies to address these disparities, contributing to more equitable digital competence in higher education.
