Abstract

Introduction:
During the COVID-19 pandemic, Bangladeshi students had to deal with drastic changes. In-person education was suspended, and online education was introduced along with movement restrictions within the community. This study aimed to assess the prevalence of stress, depression, and their combination among Bangladeshi students and evaluate their association with demographic factors and media usage during the pandemic.

Methods:
A cross-sectional study was conducted online using a structured questionnaire between January 2021 and January 2022 on 1377 students by a convenience sampling method. Demographic factors along with media usage frequency were recorded. The Perceived Stress Scale-10 was used to assess stress. Depression was evaluated by the WHO-5 Well-Being Index.

Results:
The average age of the participants was 20.8 ± 3.1 years; 51.6% of them were male. The prevalence of high stress, depression, and a coexistence of high stress and depression (CHSD) was 24.8%, 49.5%, and 20.9%, respectively. These indices significantly increased in females and with increasing age groups of participants. Students with inferior self-perceived health had higher odds of suffering from stress and CHSD, whereas students with general/poor health had the highest odds of high media usage and to suffer from high stress, depression, and CHSD. Students with high stress were found to have 9.49 times and 27.9 times higher probability to suffer from depression than students with moderate and low stress, respectively.

Conclusion:
This study has identified some important factors that can act as possible indicators to evaluate the prognosis of mental health problems among Bangladeshi students during public health emergencies.

soumission à EpisciencesUnder-resourced languages encounter substantial obstacles in speech recognition owing to the scarcity of resources and limited data availability, which impedes their development and widespread adoption. This paper presents a representation learning model that leverages existing frameworks based on self-supervised learning techniques—specifically, Contrastive Predictive Coding (CPC), wav2vec, and a bidirectional variant of CPC—by integrating them with multilingual learning approaches. We apply this model to three African languages: Wolof, Swahili, and Fongbe. Our evaluation of the resulting representations in a downstream task, automatic speech recognition, utilizing an architecture analogous to DeepSpeech, reveals the model’s capacity to discern language specific linguistic features. The results demonstrate promising performance, achieving Word Error Rates (WER) of 61% for Fongbe, 72% for Wolof, and 88% for Swahili. These findings underscore the potential of our approach in advancing speech recognition capabilities for under-resourced languages, particularly within the African linguistic landscape.Les langues sous-dotées rencontrent d'importants obstacles en reconnaissance vocale en raison du manque de ressources et de la disponibilité limitée des données, ce qui freine leur développement et leur adoption à grande échelle. Cet article présente un modèle d'apprentissage de représentations qui s'appuie sur des cadres existants basés sur des techniques d'apprentissage auto-supervisé — en particulier le Contrastive Predictive Coding (CPC), wav2vec, et une variante bidirectionnelle du CPC — en les intégrant à des approches d'apprentissage multilingue. Nous appliquons ce modèle à trois langues africaines : le wolof, le swahili et le fongbe. L'évaluation des représentations obtenues dans une tâche en aval, la reconnaissance automatique de la parole, en utilisant une architecture similaire à DeepSpeech, montre la capacité du modèle à discerner des caractéristiques linguistiques propres à chaque langue. Les résultats démontrent des performances prometteuses, avec des taux d'erreur de mots (WER) de 61 % pour le fongbe, 72 % pour le wolof et 88 % pour le swahili. Ces résultats soulignent le potentiel de notre approche pour faire progresser les capacités de reconnaissance vocale des langues sous-dotées, en particulier dans le contexte linguistique africain.

Restoration of degraded ecosystems is crucial for the conservation of biodiversity and the provision of ecosystem services. In this study, we evaluated the success of forest restoration efforts in Buner District, Pakistan, by assessing tree species diversity and forest structure. The study area was divided into assisted natural regeneration sites and plantations. Altogether thirty sites (by fifteen for assisted natural regeneration and for plantations) were randomly selected, covering the entire area. The result revealed that the assisted natural regeneration sites comprised thirteen diverse species dominated by Pinus roxburghii (54.78%), followed by Dodonaea viscosa (12.14%). In comparison, the plantation sites consisted of sixteen various species dominated by Eucalyptus camaldulensis (77.45%), followed by Robinia pseudoacacia (8.77%). The results further indicated that the average survival rate of the study area was 58.49% with the highest survival rate of 82.45% at the Ambela site and the lowest survival rate of 37.04% at the Budal site. Moreover, the number of exotic species used in plantations was limited; however, their proportion in the study area was much higher (91.15%) than that of the indigenous species (8.85%). A correlation matrix was developed to understand the relationship between seedling density (as a dependent variable) in naturally regenerating sites and influencing factors (as explanatory variables). Results showed that grazing, grass cutting, mean temperature and disturbance negatively correlated with seedling density, whereas elevation and annual precipitation positively correlated. Also, a stepwise linear regression model between seedling density and influencing factors was developed.

Introduction: Humans as social creatures need help from other humans in living their daily lives. Because, there are things that humans cannot do without the help of other people. Apart from this, humans in their lives also have 3 (three) basic needs, namely: primary, secondary and tertiary needs. Facing these needs, both humans and companies always want to fulfill them all because they basically want to live a decent life and always have enough. To be able to meet these needs, what often happens is that people and companies do not buy goods in cash but rather in installments or on credit.Purposes of the Research: Can a collection agency be said to be an employee? and what is the form of legal protection for collection agencies that take motor vehicles that are objects of credit guarantee.Methods of the Research: The research method used is a normative or literature legal research method.Results of the Research: The legal relationship between the debt collector and the debtor, namely the Billing Agency in doing its work acts as a lessor based on a power of attorney. The legal basis for the Billing Agency in carrying out its duties is carried out based on the granting of power of attorney from the lessor to the Billing Agency as stipulated in Article 1792 and Article 1795 of the Civil Code regarding special power of attorney.
Electron Diffraction: An Essay Solely based on Classical Electromagnetic Theory
Authors:   Independent Researcher, Brazil, R Panicali Antônio 
Published: February 2025

This paper discusses up to what point the fundamental two slits electron diffraction experiment can be modelled as a purely classical electromagnetic
scattering problem [1]. The trajectories of single point charges (electrons with no spin) are computed as they pass, one by one, between two ungrounded
perfectly conducting spheres, all computations being exclusively based on classical electromagnetic theory [2]. The computed particles trajectories clearly
exhibit “interference like” behavior like those predicted by quantum theory, namely
•	Particles trajectories deviations depending on the accelerating voltage, spheres radii, separation (gap) and initial particle coordinates
•	Trajectories exhibiting velocity/energy discontinuities similar to quantum trajectories
•	Depending on the overall system dimensions, the energy jumps associated to observed trajectory discontinuity have been found to bear a clear
association to the energy jumps in quantum systems as expressed in terms of Pank´s constant h.

Published: February 2025

This paper deals with the issue of Affirmative Action policies, specifically their applicability, through the system of racial quotas used by higher education institutions in Brazil and the United States of America to guarantee rights denied to vulnerable groups accumulated throughout history. It emphasizes the appreciation of the principle of equality from the point of view of materiality, as enshrined in the 1988 Political Charter. It analyzes the decisions handed down by the Supreme Courts of those countries, focusing on the most recent decisions, such as the STUDENTS FOR FAIR ADMISSIONS, INC. V. PRESIDENT AND FELLOWS OF HAVARD COLLEGE. This work, therefore, allows us to understand the importance of adopting these special measures as an instrument capable of minimizing historical inequalities and building a society founded on the dignity of the human person, more just for all.

Abstract. Andreybulakhite, ideally Ni(C2O4) ⋅ 2H2O, is a new member of the humboldtine group, named in honour of Andrey Glebovich Bulakh of Saint Petersburg State University. The mineral was discovered at the Nyud-II (Nud-II) Cu–Ni sulfide deposit, Monchegorsk mafic–ultramafic pluton, Kola Peninsula, Russia. Andreybulakhite forms segregations of platy to prismatic crystals up to 2×1×1 µm in size that are localized in the upper part of the fruiting bodies (apothecia) of Lecanora cf. polytropa lichen, whose colonies overgrow the oxidized surfaces of pyrrhotite–pentlandite–chalcopyrite ore. The mineral is monoclinic, with space group C2/c, a=11.8392(5) Å, b=5.3312(2) Å, c=9.8357(7) Å, β=126.723(5)°, V=497.59(3) Å3 and Z=4. The Raman spectrum of andreybulakhite contains the following bands (cm−1): 1701 (C=O stretching vibrations and/or multiphonon processes); 1621 (H2O bending vibrations); 1454 and 924 (C–O and C–C stretching modes); 597 (Ni–O stretching, C–C–O and O–C–O bending vibrations); and 550, 307 and 226 (predominantly Ni–O stretching and deformation modes). The absorption bands of the infrared spectrum are (cm−1) 3389 (O–H stretching vibrations), 1640 (H2O bending vibrations), 1357 and 1315 (C–O stretching, C–C stretching), and 818 (Ni–O stretching, C–O and C–C stretching, C–C–O and O–C–O bending vibrations). The empirical formula calculated on the basis of (Ni + Cu + Mg + Co) =1 atom per formula unit is (Ni0.63Cu0.27Mg0.08Co0.02)Σ1.00(C2O4) ⋅ 2H2O. The absence of iron in the mineral is a result of oxidative Ni2+/Fe3+ fractionation during the secondary aqueous alteration of Ni- and Cu-rich sulfides. Andreybulakhite has synthetic Ni and Co counterparts; the latter implies the possibility of formation of its Co analogue in a related cobalt-rich environment.

The functional purpose of the parts is largely determined by the quality parameters of their work surfaces. Currently, surface plastic deformation is an effective method of finishing and hardening treatment, ensuring high quality of the working surfaces of the parts. This method provides a complete change in the initial roughness and forms a new regular surface profile of the part. The study was carried out within the framework of the AP 19680395 project "Study of the stress-strain state of deposited parts and development of a method for reducing their deformations in the processes of surface plastic deformation" under grant funding of the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan. The article investigates the effect of finishing and hardening treatment modes by surface plastic deformation on the formation of a new microrelief of the treated surface of the part. The results of experimental studies on the influence of finishing and hardening treatment modes on the surface roughness of the part are presented. It is determined that the deformation of surface roughness irregularities is of an elasto-plastic nature and working forces during processing due to an increase in the contact area. The analysis of the results indicates an almost linear dependence of the roughness on the modes of finishing and hardening treatment. It was found that in the range of variable parameters with increasing speed, number of passes and decrease in feed, the roughness value approaches the optimal ones, which are regulated by technical conditions. Under the same processing conditions, the roughness of shafts made of 50X steel exceeds the roughness parameters of shafts made of 45 steel by 15-30%.

В данной статье представлены методические принципы выбора оптимального варианта развития транспортно-логистической структуры. Рассмотрены четыре категории методов для исследования мощности транспортно-логистического объекта, представлены результаты сравнительного анализа методов с выделением преимуществ и недостатков их применения при наличии инфраструктурных ограничений. Инфраструктурные ограничения выражаются в недостатке пропускных и перерабатывающих способностей отдельных элементов в общей транспортно-логистической структуре, в наличие «узких» мест, препятствующих доступу на инфраструктурные объекты. На примере железнодорожной станции, обслуживающей два направления и три терминала, представлены результаты аналитических расчетов, которыми установлено наличие лимитирующих элементов в инфраструктуре станции, ограничивающих дальнейший рост размеров движения и переработки поездов. В целях предотвращения истощения мощности железнодорожной станции требуется разрабатывать ряд технических мероприятий по снятию инфраструктурных ограничений. В статье обосновано применение комбинированного подхода к анализу и оценке работы объекта, который базируется на аналитических методах и методах имитационного моделирования.
Skeptical Baconianism: David Hume, Scientific Christianity, and the Controversy Surrounding Miracles
Authors: Morales Alexander W. 
Published: February 2025

Abstract
This article shows how David Hume’s notable essay “Of Miracles” responds to the exigency of scientific Christianity by articulating a rationale for divorcing the concerns of English empiricism and Protestantism while also attempting to liberate secular inquiry from religious interference. What it calls skeptical Baconianism denotes how Hume altered Francis Bacon’s cultural grammar to reveal the epistemological incommensurability between science and religion and appeal to the strong anti-Catholic and proscientific sentiments of British culture by way of equivocation. In so doing, it shows how Hume attacks the epistemological foundations of scientific Christianity while also exploiting the theological prejudices of English Protestants in the eighteenth century.
