Cosmic Origin of Fluorine: The Open Cluster Perspective
Authors:   , Bijavara Seshashayana Shilpa
Published: September 2024

The study of open clusters enables the determination of accurate values for a multitude of variables, as the stars within them are expected to have a con­sistent age, distance, and chemical content. Consequently, they are optimal for elucidating the cosmic genesis of complex elements, such as Fluorine. The objective of this project is to analyze the abundance of Fluorine in 13 open clusters, in which we have observed 31 stars in total. Additionally, eight field stars have been included in the analysis. This is the most exhaus­ tive and homogeneous database to date, which has been designed to derive Fluorine abundances across the galactic disk. While the principal objective is to comprehend the distribution of galactic Fluorine, the abundances of Cerium are also derived in order to elucidate the interrelationship between Fluorine and s­process elements. In addition to the aforementioned elements, the abundances of Magnesium are derived in order to facilitate the categorization of the field stars in the low­𝛼­ and high­𝛼 sequences, which is of importance for our method of determining stellar parameters. The abundances of Fluorine and Cerium are compared with metallicities, ages, and galactocentric distances in order to provide valuable insights into the origin of these elements through galactic chemical evolution models. The spectra were collected using the high­resolution GIANO­B instrument, which operates at the 3.58­meter Galileo National Telescope in the near­ infrared wavelength range. The Python version of Spectroscopy Made Easy was employed to analyze the spectra and derive stellar parameters as well as abundances. The H­band region was used to derive stellar parameters. The stellar parameters were obtained by analyzing the OH, CN, and CO molecular lines and band heads in addition to Fe I lines. K­band HF lines (𝜆𝜆 2.28, 2.33 𝜇m), three K­band Mg I lines (𝜆𝜆 2.10, 2.11, 2.15 𝜇m), and two H­band Ce II lines (𝜆𝜆 1.66, and 1.71 𝜇m) were used to derive Fluorine, Magnesium, and Cerium abundances, respectively. When compared with theoretical models, the observed trends suggest that both asymptotic giant branch stars and massive stars—including a proportion of fast rotators that are likely to increase with declining metallicity—are necessary to explain the cosmic origin of Fluorine.
Exploring ways of empowering pupils inphysical education through circus: an action research project
Authors:   , Lindberg Matilda
Published: September 2024

The empowerment of children is emphasized in a variety of contexts. For example, the Convention on the Rights of the Child mandates opportunities for children to be heard and to express their opinions, and the Swedish compulsory school curriculum advocates democratic teaching methods. Despite this, research shows that children’s influence in school remains limited and that democratic ways of working are particularly lacking in physical education. Therefore, this study proposes changes to physical education. The aim of this action research project was to explore ways of empowering pupils in physical education. The study involves ten-year-old children from diverse cultural and linguistic backgrounds, their physical education teacher, and a teacher-researcher. The study is at the intersection of three different fields in relation to physical education: influence, language, and creativity. Exploratory circus activities are used as a means to empower pupils and challenge the conventional structure of the subject. The study offers multiple contributions, such as practical suggestions for empowering pupils in physical education and the complex interplay between theory and practice. The findings show that physical education can serve as a platform for children to be creative, express themselves in a variety of ways, and exert influence. However, the findings reveal that empowering pupils can be a challenging process for a teacher because of prevailing norms in school, ingrained teaching habits, and both the teacher’s and pupils’ previous experiences and preconceptions of what education, and physical education in particular, entails. Finding ways to empower pupils means finding ways for teachers to share power equitably with pupils. Teaching and learning circus in physical education contributes significantly to critical thinking and acting upon how education is constructed and conducted.

Children with cancer can experience various problems both physically and psychologically. The high symptom burden experienced by children can cause children to feel depressed and can affect the children’s quality of life. This study aimed to see the influence of symptom burden in children’s quality of life. This study used descriptive correlative design with a cross sectional approach. The research was conducted in the pediatric ward at Prof. I.G.N.G Ngoerah Hospital. The sample in this study was 32 children who were selected using a purposive sampling technique. The data collected in this study included demographic data of respondents, child’s symptom burden assessed using the Memorial Symptom Assessment Scale (MSAS) (7-12) and children’s quality of life assessed using the PedsQL 3.0 Cancer Module. Data analysis was performed by simple linear regression. It was found that there was a significant relationship between symptom burden and the quality of life children with cancer (p=0.00005; ?=0.05). Symptom burden and quality of life had a strong relationship (r=0,685) and had a negative pattern. Symptom burden was also found to affect children's quality of life by 46,9%.

Liver fibrosis and conversion from normal liver architecture to abnormal nodules in patients with hepatic cirrhosis cause the liver to fail to perform its function (decompensate) and cause complications, namely hepatic encephalopathy, whether it is latent/asymptomatic hepatic encephalopathy (covert hepatic encephalopathy) or overt hepatic encephalopathy. The Animal Naming Test (ANT), which is a test with simple verbal questions to identify a person's mental function, can be used to determine mental function disorders associated with hepatic encephalopathy. This study aimed to identify the application of Evidence Based Nursing (EBN), namely the use of the ANT as a simple cognitive function test that can be used as an initial screening for cognitive impairment, especially latent/covert in patient with hepatic cirrhosis who is  not identified with routine clinical assessments available, namely verbal questions to assess orientation in time, place and person; and clinical assessments using West Haven Criteria (WHC). This study is an EBN application study that took a total sampling of 16 people, all patients with hepatic cirrhosis who underwent hospitalization in one internal medicine ward in one national referral center hospital in Jakarta. The application of EBN is done by using ANT to identify the presence or absence of cognitive function impairment in cirrhotic patients and comparing it with routine assessments performed. ANT applied to 16 cirrhotic patients was able to identify 12 patients with cognitive impairment, which is 8 more people when compared to using the WHC assessment of 4 people, and not detected or 0 people when using the assessment of verbal questions of time, place and person orientation. ANT can be used as one of the initial assessments and screenings to detect impaired cognitive function in patients with hepatic cirrhosis.

Patients are hospitalized often experience impaired sleep quality, especially in patients with critical conditions resulting from failure to adapt to a new environment such as patients in the High Care Unit (HCU). This study aims to determine the relationship between coping mechanisms and sleep quality in HCU patients at Ngimbang Hospital. This study used a correlational analytic design with a cross-sectional approach on 35 patients at Ngimbang Hospital, which were taken using consecutive sampling techniques in March-April 2023. Data were collected using a questionnaire on coping mechanisms and sleep quality. Data were analyzed using the pearson test. The results showed that 21 patients had maladaptive coping mechanisms and 14 patients had adaptive coping, while 31 patients had fairly good sleep quality, 3 patients had poor sleep quality and 1 patient had good sleep quality. The result of the statistical test was the Pearson correlation value of rs = 0,581 with a significance value of p = 0,000 meaning that there is a relationship between coping mechanisms and sleep quality in HCU patients at Ngimbang Hospital with a positive correlation strength. Coping mechanisms are needed in controlling one's emotions. This can cause anxiety so that it can result in good quality sleep. Other factors that can cause HCU patients to have moderate sleep quality are the environment such as the sound of monitors from other patients and room light. To improve the quality of good sleep, patients can self-identify emotionally so that anxiety does not arise which can lead to stress.

Published: September 2024

Objective: The article analyzes whether there is an association between the different levels of the BoP and the area of residence with the variables of access to essential utilities in a region of Colombia.
 
Theoretical Framework: The literature review addresses the concepts of access to essential utilities and the BoP Population.
 
Method: The data analyzed comes from 2,394 homes in the Norte de Santander region (Colombia), which were segmented by poverty conditions, resulting in 1,521 in the BoP. To establish the association between variables, the Mann Whitney U test was used; the magnitude of the association has been determined using Cramér's V coefficients.
 
Results and Discussion: Results show that cooking fuel, excreta disposal, and urban waste management services have a high association with the socioeconomic levels at the BoP; while the drinking water service has a moderate association, yielding a Cramer V value of 0.47. Regarding the area of residence, the independence between the variables Access to essential utilities and Area of residence is rejected; that is, they are associated. Little interest was evident on the part of public and private organizations in the essential services sector in serving this market segment, by not including it in their marketing targeting strategies. The finding was also that people from the BoP in Norte de Santander, Colombia, who reside in urban areas, have better access to these services than those in rural areas, confirming the hypotheses raised based on similar studies carried out in regions from Asia.
 
Research Implications: These results leads to recommending that companies in the essential services sector that have the BoP as their target market make a distinction in marketing strategies between the urban and rural markets of the BoP.
 
Originality/Value: The study uses an innovative socioeconomic level classification method that facilitates comparison with other regions by not using income level as the only variable.

Investigating the Funding of Teacher Education and Teacher Employment Prospects in the Face of National Student Financial Aid Scheme (NSFAS) and Fundza Lushaka Bursary Scheme in South Africa
Authors: Dr. Barber Mbangwa Mafuwane
Published: September 2024

The funding of education in South Africa, particularly post-secondary education, has proved to be a difficult and highly contentious issue. The funding challenges in this sphere sit high in the agendas of organizations such as Section 27 (though one of its priority areas is basic education), and at the very extreme and radical end, the 'fees must fall campaign.' These organizations emerged through the provisions of section 29 of the Constitution of South Africa, section 29 1(b), which obliges the state to provide further education through reasonable measures and make the same progressively available and accessible. This paper argues for clarity on the binary funding models, specifically for teacher education and the concomitant discrimination that emerges when those who were funded through the Fundza Lushaka bursary scheme are preferred for employment while their NSFAS counterparts are not. The central argument is that both models source their funds from the national treasury, but one is more preferred than the other. Secondly, a question arises as to why we have two funding models for the same purpose instead of channelling the funds through one model and ensuring that, in the end, all the beneficiaries stand the same chances of employment. This paper, therefore, hypothesizes that the government deliberately discriminates against some of the recipients of educational support, given that the two models have different qualification criteria for funding.
Perceived Social Determinants of Women Criminality in Informal Settlements in Kiambu County, Kenya
Authors: Ibrahim Mulinge Pius  , Monicah Buyatsi Oundo  , Agnes Karambu Maigallo
Published: September 2024

There is an inclination of there being more men than women in prisons despite the point that most incarcerated men have close women allies in crime. This social collaboration suggests the existence of relatively similar numbers of men and women criminality with more protective dynamics that keep women offenders away from contact with law enforcement officers. The presence of unprosecuted female offenders in the general population poses the risk of the propagation of criminal activities in society through social interaction. To mitigate this trajectory, there was a need to examine perceived social determinants of women's criminality in informal settlements in Kiambu County in Kenya. The study employed the descriptive survey research design. A sample of 380 respondents was selected using purposive sampling, proportionate sampling, and simple random sampling techniques from a population of 40,050 residents of the informal settlements. Questionnaires and focus group discussion guides were used to collect the required data. The chi-square test statistics, frequencies and percentages were adopted for data analysis. The findings indicated that family structure, marital status, alcohol and drug abuse, peer pressure, level of education, cultural norms and media exposure were determinants of women's criminality. It was recommended that Law enforcement officers consider eradicating the use and misuse of alcohol and drugs in an attempt to curb women criminality in informal settlements; women in informal settlements consider living within family structure setups in order to mitigate the tendencies of engaging in criminal activities and policymakers in the ministry of education to initiate programs aimed at increasing literacy levels and reinforcing value-based cultural practices among women in informal settlements.

Published: September 2024

One of the ways used by the Indonesian government so that people living in and around the forest can participate in managing the forest while getting economic and environmental benefits is through Social Forestry (Perhutanan Sosial) with five schemes offered according to the characteristics of the community. One of the schemes implemented by the people of Intu Lingau and Sembuan Villages is the Village Forest  (the so-called Hutan Desa-HD). The Village Forest is still in the initial stages of implementation; of course, it is interesting to study how the community manages the village forest, what the benefits are, what problems they face and how they are resolved. The aim of this research was to examine the implementation of Village Forests, the problems or conflicts that arise and the mechanisms for resolving the problems.
This research was carried out in Intu Lingau and Sembuan Villages, East Kalimantan Province, Indonesia, from 2023 to 2024 with a focus on Village Forest management, which is operationally carried out by the Village Forest Management Board (so-called LPHD-Lembaga Pengelola Hutan Desa). Data was collected using direct field surveys, focus group discussions (FGD) with LPHD and in-depth interviews with key respondents. The information and data collected were analyzed using the descriptive qualitative method. The Sustainability principles of Ostrom and Successful Principles of Agrawal were also used for validation of the implementation of Village Forest. 
The results of the research showed that the implementation of the Village Forest that has been carried out by the LPHD includes taking steps to secure the Village Forest area by making boundary marks around the area, carrying out area patrols, and operationally managing the Village Forest through five Social Forestry Business Groups (so-called Kelompok Usaha Perhutanan Sosial-KUPS) in Intu Lingau and seven KUPS in Sembuan. In the implementation of Forest Village, there were several internal and external conflicts. The conflict resolution mechanism used is negotiation and consensus because it depends on the intensity and who was involved in the conflict. It is recommended that the management board strongly support KUPS in running the Program for the benefit of the community.
Gendered Property Rights in Farmer-Led Irrigation Development in Nyando Sub-County, Kenya: Myth or Reality?
Authors: Elizabeth Achieng Aduma  , Dr. George Mark Onyango  , Dr. Mathews Dida
Published: September 2024

Gendered Property Rights are considered the decision-making powers of women over the disposition of a resource. This entails the access and control of the resource, and in this study, we use Farmer-led Irrigation Development (FLID) as the arena in which we determine whether decision-making has changed for women. FLID is an emerging form of irrigation that places the individual as the focal person in decision-making and therefore provides a rich environment for testing the true nature of Gendered Property Rights. The status of women in irrigated agriculture has received extensive coverage in current studies, with the studies showing men as having control over key resources and, therefore, having decision-making power over the same. How resources are used, what crops are planted, how the income generated is prioritized as well, and how labour is divided in the household are decisions made by men. However, gaps still exist in FLID, and this paper set out to explore how FLID has influenced Gendered Property Rights; the focus is on who has control over resources and whether there has been a shift in the everyday narrative of control being male-dominated. We use identified indicators to monitor outcomes in two different aspects: control over key resources (household assets, livestock, farming tools, and irrigation equipment) and decision-making about key issues (land, household, income generation, and water management). The study uses snowball sampling to identify 385 FLID irrigators in Nyando Sub County, Kenya, and twelve participants in 4 gender-differentiated FGDs from Ahero and Kabonyo/Kanyagwal wards. Results demonstrate that there has been a shift in the control over key resources, with the narrative moving towards joint control. Further, the study shows that joint control in key resources directly translates to joint control in decision-making and greatly increases the benefits accrued from irrigation practices. However, this gap is narrowing at a very slow pace and requires a shift in mindset as well.
Grandparents’ Characteristics by Age, 2022
Authors: Westrick-Payne Krista
Published: September 2024

The average age of grandparents in the U.S. in 2022 was 68 years. Grandparenthood is more common among older adults (aged 65 and older) than those in midlife (aged 40-64). In 2022, the percentage of older adults who were grandparents (67%) was more than 2.5 times greater than the percentage among those in midlife (24%). Data from the 2023 panel of the Survey of Income and Program Participation (SIPP) are used to update Wu, 2018 & Westrick-Payne, 2023 comparing midlife grandparents to those at older ages across demographic characteristics in 2022. The SIPP is a nationally representative household-based survey that directly asks respondents if they are a grandparent, making it one of the few national surveys that identify non-resident grandparents. This profile is number three in our 2024 series on grandparents in the U.S.
Continual Extraction of Semantic Relations using Augmented Prototypes with Energy-based Model Alignment
Authors: Pham Trang
Published: September 2024

Continual relation extraction (CRE) is a critical task in natural language processing thataims to learn new relation types incrementally while preserving knowledge of previously learnedrelations. However, existing CRE models often struggle with catastrophic forgetting and inefficientutilization of memory. In this paper, we propose a CRE model that leverages class-specific prototypesand energy-based latent alignment to address these challenges. Our approach stores relation prototypes instead of real data points, enriching them with Gaussian noise during training. We incorporatecontrastive learning to obtain effective representations for memory prototype data and introduce anEnergy-based Latent feature space Alignment (ELI) module to mitigate representational shift acrosstasks. We evaluate our model on two benchmark datasets: FewRel, a balanced few-shot relationclassification dataset, and TACRED, a large-scale imbalanced relation extraction dataset. Extensiveexperiments demonstrate that our proposed method consistently outperforms state-of-the-art CREmodels across multiple tasks, with improvements of up to 4% over existing methods. This consistentsuperior performance highlights our model effectiveness in addressing the challenges of continual relation extraction, particularly in maintaining performance across a sequence of tasks while mitigatingcatastrophic forgetting.

Published: September 2024

The in-situ moisture conservation and mulching are techniques that help retain moisture at the root zone, reduce evapotranspiration, and increase the time of infiltration for maize production. This study was focused on the evaluation of the best moisture conservation techniques in combination with mulching under rain-fed conditions for maize production in the study area. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Five treatments, namely, control (without structure and mulching), mulching, furrow ridge with open-ended furrow with mulching, furrow ridge with closed-ended furrow with mulching, and tied ridge with mulching, were compared for two consecutive seasons (2021 and 2022) in terms of soil moisture conservation and maize grain yield. The highest mean grain yield (6134.84 kg ha-1) and soil moisture content were recorded from the plot of T5 (Tied Ridge + Mulching). The result revealed that tied ridges with mulching showed better grain yield and conserved moisture over the others, followed by furrow ridges with close-ended furrows with mulching, respectively. Therefore, tied ridges with mulching as in-situ moisture conservation practices is an effective technique for storing moisture and increasing the time of infiltration as compared to other practices.

O presente artigo propõe apresentar a poética de Ana Mafalda Leite, evidenciada a partir das seguintes obras: Outras fronteiras: fragmentos de narrativa (2017) e O amor, essa forma de desconhecimento (2010). A proposta se faz pertinente ao considerar as discussões acerca de trânsitos e poesia, buscando envolver os elementos constituintes dos versos da poeta e uma leitura atrelada à perspectiva de pertença afetiva. De forma que a relação da pertença afetiva com Moçambique, como também uma perspectiva que considera a presença do Oceano Índico como elemento literário nas produções moçambicanas e reitera esse elo, promove um lugar de importância e paradoxos do lirismo nessa produção. Além das representações do amor nas duas obras e as vozes que o sujeito lírico apresenta a partir dos movimentos que interpelam essas construções. Ao considerar como também a noção das travessias e as ambivalências que constituem a produção literária, elegemos as discussões e críticas de pesquisadores como Bhabha (2003), Noa (2017), Cunha (2010), Secco (2015). Falconi (2013), Maquêa (2020).

Invasive pituitary adenoma presenting with cerebrospinal fluid rhinorrhea and meningitis – A case report
Authors: Javed Zanib , Saeed Zunaira , Khan Sibgha , Ali Laghari Altaf
Published: September 2024

Background:

Most pituitary neuroendocrine tumors are benign, except some adenomas that show invasiveness and are called invasive pituitary adenomas. These are challenging and rare pathologies.

Case Description:

We present a case of a 40-year-old male who presented to the emergency with seizures, rhinorrhea, headache, and drowsiness. Radiology images showed a sellar mass with supra-sellar extension and pneumocephalus. The pituitary profile was within normal limits. The patient underwent bifrontal craniotomy and maximum safe resection of the lesion with cerebrospinal fluid (CSF) leak repair and lumbar drain insertion. Histological examination and immunohistochemical stain were consistent with pituitary adenoma. Postoperatively, there was no CSF leak, and the patient’s Glasgow Coma Scale improved.

Conclusion:

Rhinorrhea is a unique presentation for pituitary adenoma. According to the current literature, surgery is the only effective treatment as part of the management of invasive pituitary adenomas, along with a multidisciplinary approach.
Spontaneous spinal epidural hematoma in infants: A case report and review of the literature
Authors: Hammoud Marouane , Mohammed Hmamouche Oualid , Chakour Khalid , Chaoui Mohammed El Faiz
Published: September 2024

Background:

Spontaneous spinal epidural hematomas (SSEHs) are exceedingly uncommon, especially in infants, with only two reported cases. Diagnosis can be delayed due to the nonspecificity of presenting symptoms.

Case Report:

We present a case of SSEH in a 10-month-old boy admitted to the pediatric emergency department with a 5-day history of progressive lower extremity motor weakness. There was no history of prior trauma. Magnetic resonance imaging of the spine revealed a posterior epidural hematoma extending from C7 to L4. After hematoma evacuation, the patient’s neurological status gradually improved, and no sensorimotor deficit was present 3 weeks postoperatively.

Conclusion:

Our case suggests that surgical intervention can lead to an excellent prognosis for SSEH in infants, even if the diagnosis is delayed.

Рассматриваются вопросы рационального распределения функций между звеньями комплекса управления беспилотными летательными аппаратами и оптимизации режимов их загрузки для повышения автономности и надежности. Функции распределяются между тремя системными составляющими (звеньями) комплекса управления: наземными автоматическими станциями командно-измерительных систем, бортовыми системами управления летательных аппаратов и операторами. Часть функций назначается однозначно без альтернатив, а функции, которые могут существенно пересекаться и выполняться разными элементами системы управления, требуют специального рассмотрения. В ряде случаев распределение функций, установка режимов загрузки и вложение средств в построение многофункционального комплекса управления допускают постановку оптимизационных задач, что представляет существенный интерес. Приведены примеры возможных постановок некоторых оптимизационных задач в общем виде, даны обобщающие выводы.

The article considers the issues of rational distribution of functions between the links of the unmanned aerial vehicles control complex and optimization of their loading modes for increasing autonomy and reliability. Functions are distributed between the three system components (links) of the control complex: ground automatic stations of command and measurement systems, onboard control systems of aircraft and operators. Some functions are assigned definitely without any alternatives, and functions that can significantly overlap and be performed by different elements of the control system require special consideration. In some cases, the distribution of functions, the installation of loading modes and investment in the construction of a multifunctional management complex allow the formulation of optimization problems, which is of considerable interest. The examples of possible statements of some optimization problems in general form are given, as well as general conclusions are made.

В статье приводятся результаты теоретического обоснования метода идентификации сложных динамических объектов при штатных условиях эксплуатации на основе запасов работоспособности и результатов статистических испытаний (метод Монте-Карло). Доказано, что имеет место монотонная зависимость вероятности выполнения заданных ограничений на допустимые отклонения невязок между результатами летных испытаний и расчетов по методу Монте-Карло и предложенной формой запасов работоспособности. Определяется случайная реализация, которая ближе всего по вероятности идентификации подходит под летные испытания и которая однозначно определяет весь перечень возмущенных параметров, внешних и внутренних возмущений. На примере применения разработанной методики и программного обеспечения идентификации к анализу пуска ракеты-носителя «Союз-2» (Л/И № 2) с космическим аппаратом «Метеор-М2.1» с полигона «Восточный» 28.11.2018 г. показана эффективность метода, позволившая выявить ряд важных неточностей математической модели системы по сравнению с результатом летных испытаний.

This paper provides the results of theoretical validation of identifi cation approach for complex dynamical plants nominal operating conditions. The proposed approach based on efficiency margins and the results of probabilistic tests (Monte-Carlo method). It is proved that there exists the monotonic dependency of fulfillment probability of feasible errors deflection specifi ed constraints between flight test results and Monte-Carlo estimations, and provided efficiency margins form. In this method we determine the random realization, which is closer in terms of identifi cation probability to fl ight tests and which is explicitly defi nes full list of disturbed parameters, internal and external disturbances. The effi ciency of the approach is shown on the example of application of this approach and corresponding identifi cation software to the analysis of carrier rocket «Soyuz-2» launch (flight tests № 2) with the spacecraft «Meteor-M2.1»… from the «Vostochny» space center 28/11/2018. This application allows us to detect the number of signifi cant inaccuracies of mathematical model versus the flight test results.

На основании статистики столкновений космических аппаратов с мелкоразмерным техногенным мусором в околоземном космическом пространстве, в статье показана актуальность создания контактных бортовых детекторов для контроля мелкой фракции космического мусора. Представлено описание конструкции, принцип действия и преимущества устройства для пространственной регистрации, измерения динамических параметров и неразрушающего улавливания мелкодисперсных частиц. Согласно данным по количественному распределению техногенного мусора и его динамических характеристик на околоземных орбитах, а также степени использования тех или иных орбит, сделаны выводы о наиболее рациональном применении данного устройства для контроля засоренности околоземного пространства.

Based on the statistics of spacecraft collisions with small-sized technogenic debris in near-earth space, the article shows the relevance of creating contact onboard detectors to control the small fraction of space debris. The design, operating principle and advantages of the device for spatial registration, measurement of dynamic parameters and non-destructive capture of fine particles are described. According to the data on the quantitative distribution of technogenic debris and its dynamic characteristics in near-earth orbits, as well as the degree of use of certain orbits, conclusions are made about the most rational use of this device for monitoring the debris of near-earth space.

На основе системного подхода разработана информационно-технологическая модель кислородного баланса водотоков при загрязнении нефтяными выбросами от аварийных разрушений подводных переходов нефтепроводов. Разработаны алгоритмы решения дифференциальных уравнений системного кислородного баланса в одномерном приближении в зависимости от времени для оценки динамики биохимической потребности, дефицита и концентрации кислорода в воде, реализованные в прикладной среде MathСad. Решена практическая задача по вычислению расстояния от створа аварийного выброса нефти до створа максимального дефицита кислорода в водотоке при равномерной и постоянной скорости течения. Полученные результаты могут быть использованы при разработке автоматизированных имитационных моделей оценки ущерба окружающей среды при аварийных разливах нефти от аварийных разрушений подводных переходов нефтепроводов.

In this paper, based on the system approach, an information and technological model for the oxygen balance of watercourses was developed in the event of pollution by oil spills from accidental destruction of underwater oil pipeline crossings. Algorithms for solving the differential equations of the system oxygen balance in the one-dimensional approximation as a function of time have been developed to estimate the dynamics of the biochemical demand, oxygen deficiency and concentration in water, realized in the MathСad application environment. A practical problem was solved for calculating the distance from the emergency discharge line to the maximum oxygen defi cit in the watercourse with a uniform and constant fl ow velocity. The obtained results can be used in the development of automated simulation models for assessing environmental damage in emergency oil spills from accidental destruction of underwater oil pipeline crossings.
THE BIRTH OF FRUMKIN ELECTROCHEMICAL SCHOOL UPON KARPOV PHYSICO-CHEMICAL INSTITUTE

Published: September 2024

В работе рассмотрены направления исследований основателя известной электрохимической школы акад. А.Н. Фрумкина в конце 20-х–начале 30-х гг. XX века, после его переезда в Москву. Этот начальный период становления школы был отмечен награждением А.Н. Фрумкина премией имени В.И. Ленина (1931). Доминирующая тематика работ по сорбционным процессам на углях указывает на то, что премия была присуждена именно за эти исследования, имеющие высокую практическую значимость. Научные биографии соавторов работ А.Н. Фрумкина по «угольной» тематике (Р.Х. Бурштейн, Б.П. Брунс, С.Д. Левина, С.С. Васильев) показывают, что генетически школа Фрумкина связана с выдающимися представителями более раннего периода развития электрохимии в России и Украине (в том числе И.А. Каблуковым, В.А. Плотниковым, В.А. Кистяковским).

We consider the research topics of academician A.N. Frumkin, the founder of a famous electrochemical school, at the end of 1920th and beginning of 1930th (shortly after he moved to Moscow). During this starting period of Frumkin school its founder had been awarded the Lenin Prize (1931), the highest USSR state award. As the articles devoted to sorption processes on the coals dominated during this period, one can conclude that the Prize was awarded just for this coal research, being of high interest for applications. Scientific biographies of coautors of Frumkin’s coal articles (R.Kh. Burshtein, B.P. Bruns, S.D. Levina and S.S. Vasil’iev) demonstrate that Frumkin school is genetically linked to the outstanding Russian electrochemists of the previous period, including I.A. Kablukov, V.A. Plotnikov, and V.A. Kistyakovskii.
THE FOUNDATION OF THE RUSSIAN ORTHODOX SPIRITUAL MISSION IN KOREA

В статье рассматривается начало миссионерской работы в Корее представителя Русской православной церкви архимандрита, а в дальнейшем епископа Хрисанфа (Щетковского). Содержится материал, раскрывает особенности православной миссионерской деятельности среди местного населения Кореи. Говориться о тех трудностях и с чем пришлось столкнуться на начальном этапе в деятельности миссии. Автор приходит к выводу о том, что успехи деятельности нашей миссии были менее впечатляющими, чем успехи западных миссий, в виду того, что Русская православная миссия исполняла роль только лишь своеобразного «проводника» религиозно – культурного влияния и не стремилась вмешиваться во внутренние дела этой страны в отличии от западных миссий.

The article deals with early missionary work in Korea, the representative of the Russian Orthodox Church Archimandrite and later Bishop Chrysanthus (Shatkovskogo). It contains material that reveals the peculiarities of Orthodox missionary activity among the local population of Korea. The difficulties encountered and the diffi culties encountered in the initial phase of the mission are described. The author comes to the conclusion that the success of our mission was less impressive than the achievements of the Western missions, in view of the fact that the Russian Orthodox mission played the role only a kind of «conductor» of the religious and cultural infl uence and did not seek to interfere in the internal Affairs of this country in contrast to the Western missions.
