A.A. Chuprov – An Outstanding Russian Statistician (to the 150th Anniversary of his Birth)
Authors: Eliseeva I. I. , Dmitriev A. I.
Published: February 2025

Among the great names of representatives of the St. Petersburg school of probability theory – P.L. Chebyshev, A.M. Lyapunov, A.A. Markov – Alexander Alexandrovich Chuprov stands on a par, but apart. However, his contribution to world statistics is no less valuable. The paper offers a brief overview of A.A. Chuprov’s life path and the influence that his father, Alexander Ivanovich Chuprov, had on him, helping his son obtain a double education – both in mathematics and the humanities, and introducing him to zemstvo statistics. The authors highlight the significance of A.A. Chuprov’s book «Essays on the Theory of Statistics» which evoked a keen response from leading Russian scientists and brought him to the forefront of Russian statistical science. In this work, A.A. Chuprov substantiated the need for a statistical method in both social and natural sciences. He consistently advanced the idea of a stochastic world, arguing that all data statisticians work with are nothing more than a sample: they necessarily contain a random component. All of A.A. Chuprov's works focus on finding a priori (true) characteristics based on a posteriori (observed) data. The authors of the article draw attention to A.A. Chuprov's characteristic approach to considering the logic of the statistical method in studying the stability of statistical series, the nature of the correlation relationship, and his broad outlook and understanding of the laws of development of statistical science. The cognitive potential of A.A. Chuprov was formed by a combination of Russian and European education and later by diverse scientific contacts with the foreign scientific community.

The article identifies A.A. Chuprov's place as a teacher who managed to create his school of teaching statistics. His contribution to demographic research is emphasized, especially in establishing proportions in the sex ratio and the effect of war on marriage rates. Alexander Chuprov's expertise in philosophy and mathematics, combined with his understanding of the problems of practical statistics, enabled him to foresee the future development of the theory of statistics as a mathematical statistics, i.e. a science in the centre of which are the problems of statistical estimates of general distributions and parameters.
Vespa velutina : le frelon asiatique à pattes jaunes, une espèce exotique envahissante. Historique, biologie et plan de lutte en France
Authors: Boucher Samuel
Published: February 2025

Le frelon asiatique à pattes jaunes, Vespa velutina, est une espèce exotique envahissante qui menace les écosystèmes européens depuis sa détection en France en 2005. Originaire d'Asie du Sud-Est, son introduction accidentelle s'est produite par le biais de cargaisons de poteries importées. Depuis, l'espèce s'est propagée rapidement, couvrant presque tout le territoire français en 2020 et colonisant récemment la Corse en août 2024. Morphologiquement identifiable par ses pattes jaunes et son thorax noir, Vespa velutina construit des nids souvent sphériques et situés en hauteur. Son cycle de vie annuel comprend quatre phases : fondation au printemps, croissance en été, reproduction à l'automne et hibernation hivernale. Prédateur opportuniste, il se nourrit d'abeilles, de fruits et d'autres insectes, menaçant particulièrement l'apiculture et la biodiversité. Face à cette menace, la France a adopté un plan national de lutte en 2022. Les stratégies incluent le piégeage sélectif des fondatrices, l'installation de dispositifs pour protéger les ruchers et la destruction ciblée des nids. Ces efforts nécessitent une coordination entre acteurs locaux, scientifiques et apiculteurs. Bien que ces mesures aient réduit les impacts, la vigilance reste essentielle pour limiter les dégâts écologiques et apicoles causés par cet envahisseur.
Concepciones sobre la disciplina escolar en estudiantes de primaria y secundaria

Published: February 2025

El objetivo de esta investigación fue identificar las concepciones sobre la disciplina escolar en un grupo de estudiantes de una escuela privada de Lima Metropolitana que implementa un sistema disciplinario basado en el uso de recompensas y castigos. Se entrevistaron doce estudiantes: seis de primaria (entre los 7 y 12 años de edad) y seis de secundaria (entre los 14 y 17 años de edad), haciendo uso de una entrevista semi estructurada que buscaba indagar sus concepciones acerca de la disciplina escolar y sus objetivos. Los resultados indican que los participantes de primaria y secundaria conciben la disciplina escolar como un mecanismo regulador de la conducta. En primaria, este mecanismo es reconocido con poca precisión, mientras que en secundaria se entiende como un conjunto de reglas al que atribuyen la función de manejar la conducta de las personas. A la base de esta concepción tradicional sobre la disciplina escolar se encuentra la creencia de que los estudiantes son incapaces de regular su propio comportamiento, por lo que, para los participantes, se hace necesaria la implementación de agentes externos (reglas y castigos) que faciliten la consecución de conductas deseadas por la escuela. Los resultados son discutidos a partir de la concepción piagetiana de autonomía moral. El estudio concluye con recomendaciones para la institución educativa y futuras líneas de investigación.

The Effect of Different Substrates on H₂S and N₂ Production in Biogas Production
Authors: Filikci Cevat , Marakoğlu Tamer
Published: February 2025

The gases in the biogas content, which constitute an obstacle to the more effective use of biogas for fuel purposes, are subjected to a number of physical, chemical and biological processes and are removed from the biogas. This is important in order to purify from toxic effects. Many studies have been carried out especially to remove H2S and N2 gases in biogas, which cause corrosion and bad odors.
In this study, different mixtures were determined and biogas was produced. As a result of the measurements, the biogas components of each mixture were measured using the optima gas analyzer device. H2S and N2 ratios obtained from different substrates were determined. The effect of these ratios on biogas production was analyzed. In the research, a laboratory scale application setup was established for biogas production. In this context, 3 different applications were determined and an experimental design was created. In the established application setup, biogas measurements were recorded in the computer environment for 16 days, 30 days and 43 days, taking into account the end of biogas production of the materials. During the measurements, the temperature and pH values were checked periodically and the mixing process was carried out by hand shaking every day. The applications were carried out considering 10% dry matter rate.

Authors: Vishaka K. S. , Sri Samyuktha Yadav P. , Roselin Jenifer D. , Preethi Jesia Persis , Abbiramy K. S.
Published: February 2025

Euphorbia resinifera, a member of the Euphorbiaceae family, is notable for its significant medicinal properties. Originally endemic to Morocco, this species has become cosmopolitan, spreading widely across tropical regions worldwide. This review focuses on the phytochemical properties of Euphorbia resinifera, providing a comprehensive overview of its diverse phytochemicals and their potential therapeutic applications. The review also highlights the potential for further exploration of phytochemicals in less-studied parts of the plant, such as the flowers. Our primary sources were peer-reviewed research articlesand reports from scientific databases including Scopus, PubMed, Web of Science, and SpringerLink identifying numerous novel compounds, particularly from the latex of Euphorbia resinifera. Various studies have investigated latex, while fewer studies have examined the whole plant, stem, leaves, flowers, and honey. This review underscores the need for detailed studies on the unexplored parts of Euphorbia resinifera and suggests that the identified phytochemicals, traditionally used in ethnomedicine, could be further investigated for drug development. Such research could lead to the discovery of new treatments for diseases that pose significant challenges to human health.
The Multifaceted Nature of a Woman’s Self-Existence – A Study Based on Anar’s Poems
Authors: Arivalagan Vinothini
Published: February 2025

In the world of Eelam poetry, a dedicated space for female poets emerged only after the 1980s. Over time, female poets have expanded their presence, articulating deep feminist thoughts and structuring their poetry with profound linguistic frameworks, establishing a unique identity for themselves. A poet derives themes from society, shaping not only their own literary voice but also influencing the community. In this context, this study explores the multifaceted nature of a woman’s self-existence through the deeply personal and evocative poetry of Anar, the pseudonym of IssathReehaana Muhammad Azeez. Anar, hailing from Saindamaruthu in Eastern Sri Lanka, has made a distinct mark as a female poet, crafting a powerful and authentic voice in Tamil literature.
Современные тенденции изменений месячных потоков суммарной солнечной радиации, поступающей на Азиатскую территорию России
Authors: Холопцев А.В. , Шубкин Р.Г. , Бабенышев С.В.
Published: February 2025

Актуальной проблемой безопасности при чрезвычайных ситуациях является развитие существующих представлений о факторах, значимо влияющих на межгодовые вариации пожароопасности по условиям погоды на различных участках Азиатской территории России. Одним из таких факторов в те или иные месяцы пожароопасного сезона на некоторых участках могут служить изменения месячных потоков поступающей на них суммарной солнечной радиации. На многих участках к числу значимых причин этих изменений относятся вариации оптической плотности, формирующейся над ними облачности, обусловленные динамикой температуры и влажности воздуха соответствующих слоев тропосферы, а также концентраций в них атмосферных ядер конденсации. К весьма активным ядрам конденсации относятся ионы, образующиеся в воздухе в результате входа в атмосферу космических лучей, преодолевших геомагнитное поле. Следовательно, приближение к Азиатской территории России Северного Магнитного полюса способно порождать в изменениях потоков суммарной солнечной радиации, поступающей в рассматриваемые месяцы на некоторые ее участки, те или иные значимые тенденции.

The urgent problem of safety in emergency situations is the development of existing ideas about the factors that significantly affect the inter-annual variations of fire danger by weather conditions in different parts of the Asian territory of Russia. One of such factors in certain months of the fire-hazardous season in some areas can be changes in monthly flows of total solar radiation arriving at them. At many sites, the significant causes of these changes include variations in the optical density of clouds formed above them due to the dynamics of air temperature and humidity of the corresponding troposphere layers and concentrations of atmospheric condensation nuclei in them. The very active condensation nuclei include ions formed in the air as a result of the entry into the atmosphere of cosmic rays that have overcome the geomagnetic field. Consequently, the approach of the North Magnetic Pole to the Asian territory of Russia is capable of generating certain significant trends in the changes in the fluxes of total solar radiation arriving in the months under consideration to some of its areas.
О некоторых особенностях осуществления государственного пожарного надзора в современных условиях
Authors: Седов Д.В. , Кузьмин Д.В.
Published: February 2025

В статье рассматривается ряд современных тенденций в законодательстве, которые оказывают значительное влияние на деятельность надзорных органов МЧС России. Первая тенденция («мораторий» на проверки) является вынужденной, экономически обоснованной и состоит в ослаблении контроля над деятельностью коммерческих организаций, сокращении плановых и внеплановых проверок соблюдения противопожарных норм. Вторая тенденция состоит в растущем количестве профилактических визитов, которые имеют рекомендательный характер и не оказывают административного давления на контролируемых лиц. Третья тенденция связана с отсутствием в правовом поле определения понятия «угроза жизни и здоровья людей», которое играет принципиальную роль при осуществлении государственного пожарного надзора. Указанные тенденции вызваны как объективными факторами, так и некоторыми правовыми пробелами. Целью статьи является анализ данных тенденций и их влияния на эффективность государственного пожарного надзора. В результате проведенного анализа сделан вывод о том, что «мораторий» на проверки привел к снижению внимания со стороны коммерческих организаций к вопросам обеспечения пожарной безопасности. Профилактические визиты, количество которых ежегодно увеличивается, не оказывают существенного воздействия на данную ситуацию. Отсутствие юридически закрепленного понятия «угроза жизни и здоровью людей» приводит к тому, что надзорные органы МЧС России и органы прокуратуры используют различные подходы к определению данной угрозы.

The article examines a number of modern trends in legislation that have a significant impact on the activities of the supervisory bodies of the Ministry of Emergency Situations of Russia. The first trend (the "moratorium" on inspections) is forced, economically justified and consists in weakening control over the activities of commercial organizations, reducing scheduled and unscheduled inspections of compliance with fire safety regulations. The second trend is the growing number of preventive visits, which are advisory in nature and do not exert administrative pressure on the supervised persons. The third trend is associated with the absence in the legal field of a definition of the concept of "threat to life and health of people", which plays a fundamental role in the implementation of state fire supervision. These trends are caused by both objective factors and some legal gaps. The purpose of the article is to analyze these trends and their impact on the effectiveness of state fire supervision. As a result of the analysis, it was concluded that the "moratorium" on inspections led to a decrease in attention from commercial organizations to fire safety issues. Preventive visits, the number of which increases annually, do not have a significant impact on this situation. The absence of a legally enshrined concept of “threat to human life and health” leads to the fact that the supervisory bodies of the Russian Emergencies Ministry and the prosecutor’s office use different approaches to defining this threat.

Published: February 2025

Системы пожарной сигнализации играют ключевую роль в обеспечении пожарной безопасности зданий и сооружений. Своевременное обнаружение пожара и оповещение людей о нем позволяет минимизировать материальный ущерб и, что самое главное, спасти жизни. Однако, нередки случаи, когда системы работают некорректно, выдавая ложные срабатывания или, напротив, не срабатывая при реальной угрозе пожара. В статье рассматриваются основные причины возникновения ложных срабатываний и отказов систем пожарной сигнализации, приводятся примеры типичных нарушений. Действительно, проблемы обнаруживаются еще на стадии проекта, когда заказчик пытается минимизировать затраты, иногда без учета особенностей здания, степени пожарной нагрузки. В дальнейшем, трудности могут возникнуть при эксплуатации оборудования из-за неблагоприятных условий окружающей среды, электромагнитных помех, некачественном и несвоевременном техническом обслуживании. По результатам анализа в работе представлена причинно-следственная диаграмма Исикавы, учитывающая широкий комплекс факторов, влияющих на надежность системы пожарной сигнализации. Предлагаются пути повышения надежности и эффективности работы данных устройств. Перспективным решением авторы считают внедрение многокритериальных пожарных извещателей. При этом, авторы указывают на отставание их метрологического обеспечения (в частности, методики испытаний).

Fire alarm systems play a key role in ensuring the fire safety of buildings and structures. Timely detection of a fire and notification of people about it allows you to minimize material damage and, most importantly, save lives. However, it is not uncommon for systems to work incorrectly, giving false alarms or, conversely, not working with a real threat of fire. The article discusses the main causes of false alarms and failures of fire alarm systems, provides examples of typical violations. Indeed, problems are found even at the project stage, when the customer tries to minimize costs, sometimes without taking into account the characteristics of the building, the degree of fire load. In the future, difficulties may arise during the operation of the equipment due to adverse environmental conditions, electromagnetic interference, poor-quality and untimely maintenance. Based on the results of the analysis, the paper presents the Ishikawa causal diagram, which takes into account a wide range of factors affecting the reliability of the fire alarm system. Ways to improve the reliability and efficiency of these devices are proposed. The authors consider the introduction of multi-criteria fire detectors to be a promising solution. At the same time, the authors point to the lag in their metrological support (in particular, test methods).

Published: February 2025

This research aims to exploit the potential of sappan wood (Caesalpinia sappan L.) as a bioacaricide on Boophilus microplus ticks. This research used a completely randomized design method with ticks as the research object. There were five treatments in this study, two of which were in the positive control group (Kututox) and negative control (Aquades), and three treatments in the group were given sappan wood infusion with concentrations of 25%, 50%, and 75%. Each treatment consisted of 5 replications, each replication using five ticks. The sappan wood infusion bioacaricide test was carried out in vitro, and tick death was observed for 5 hours with observation time every hour after spraying. The data obtained were analyzed using one-way variance, followed by the LSD test. Then, a probit analysis of LC50 and LC90 was performed to determine the concentration of sappan wood infusion that can kill ticks, and LT50 and LT90 were used to determine the time of death of B. microplus ticks. The research results showed that sappan wood infusion with a concentration of 75% effectively killed 50% of Boophilus microplus ticks at 0.67 hours and killed 90% of Boophilus microplus ticks at 1.17 hours. Sappan wood infusion can be an alternative bioacaricide to kill Boophilus microplus ticks

Access to published, peer-reviewed articles in special education is important to researchers and practitioners alike. However, much of the published literature base lies behind paywalls, inaccessible to many potential consumers. Although researchers can make their published work openly accessible in multiple, there is limited information on the prevalence of open-access publishing, predictors of open-access publishing, and the costs of and options for accessing paywalled articles in special education. To address these gaps in the literature, we examined articles published in 2022 in 43 special education journals (n = 1,678) and found that 55% of articles were openly accessible; reporting funding for the research, non-U.S. corresponding authors, and journal impact factor were positively associated with open-access publishing; and the average cost to access a paywalled article was approximately $36. Implications for equity, scientific progress, and the research-to-practice gap are discussed.

Published: February 2025

This research aims to compare the performance of two types of recurrent neural network models, Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), in forecasting gold prices based on historical closing price data. Historical gold price data from December 14, 2017, to March 14, 2024, was downloaded using the yfinance library. The data was normalized using MinMaxScaler and split into training and testing sets with an 80:20 ratio. LSTM and GRU models were constructed with two recurrent layers followed by a Dense layer for output. Both models were trained using the training data and evaluated using Mean Squared Error (MSE), Mean Absolute Error (MAE), and R-squared (R²) metrics. The experimental results indicate that the GRU model outperformed the LSTM model in predicting gold prices. GRU achieved an MSE of 337.70, MAE of 14.05, and R² of 0.933, whereas LSTM achieved an MSE of 808.98, MAE of 22.71, and R² of 0.839. Based on the model performance evaluation, it can be concluded that GRU consistently produced more accurate predictions closer to the actual values of gold prices compared to LSTM. This finding suggests that GRU may be a preferable choice in applications for forecasting gold prices using historical data.
