Authors: Barbosa Breno , Ribeiro Paulo Ronaldo Jube
Published: January 2025

Background: Langerhans cell histiocytosis (LCH) is a rare disease involving the cervical spine. This condition is present firstly in the thoracic spine, commonest, followed by the lumbar spine and cervical spine. In Langerhans cell histiocytosis there is excessive proliferation of pathologic Langerhans cells. It is commonly found in males with a ratio of 2.5:1. The etiology of LCH is unknown. There are three defined entities classified on their severities. Letterer-Siwe disease involves multiple organs, Hand-Schuller-Christian disease presents with bony lesions and endocrine abnormalities, and eosinophilic granuloma (EG) presents with isolated bony lesions. We describe a case-report a girl with Langerhans cell histiocytosis in cervical vertebrae.The objective of this study is to show the rare case of Cervical Spine Langerhans Cell Histiocytosis.
Method: We were a literature review with inclusion and exclusion criteria and we described a case-report.
Case-Report: A 9-month-old girl had neck pain associated with right upper limb weakness. Imaging showed infiltrative and expansive lesions in the vertebral body from C1 to C6 with spinal cord and root compression. The patient underwent a laminectomy from C2 to C5. Histopathological was suggestive of LCH.
Conclusion: Despite the rarity of the disease, Langerhans cell histiocytosis can be treated with a surgical approach when neurologic deficits are present.

Published: January 2025

In recent years, there has been an increasing practice of Virtual Exchanges (VEs) to help EFL learners, especially ESP graduates develop their intercultural abilities and language skills. This research study aims to gain insight into how e-collaborative learning can serve as a fertile environment that supports their intercultural development. To this end, we used an online non-participant observation to record students' talk-in-interactions that were later analysed following a deductive theme-based approach using Byram (1997) model of intercultural competence, and Kramsch (1993) “sphere of interculturality” was adopted to describe the how of intercultural development. The sample population consisted of 19 ESP students from the Department of English Language at Abou Bakr Belkaid University, Algeria paired with students from East Carolina, Colombia and India. Results revealed that e-collaborative learning in VE is beneficial and could help ESP students enhance their intercultural abilities by co-constructing a third culture space. Overall, the researchers encourage ESP students to go through VE experiences to meet modern society’s needs.

Evolution of radial stresses in direct simple shear testing: integration of principal stress rotation theory and SANISAND constitutive modeling
Authors: Azeddine Chehat
Published: January 2025

This investigation presents a comprehensive analysis of radial stress evolution during Direct Simple Shear (DSS) testing through the integration of principal stress rotation theory and advanced constitutive modeling. The study addresses a fundamental limitation in DSS testing: the inability to directly measure radial stresses during shearing. Two complementary approaches are implemented to investigate this phenomenon. First, a theoretical framework based on principal stress rotation demonstrates distinct evolution patterns between loose (φ = 33°) and dense (φ = 37°) sands, revealing that radial stresses can exceed vertical confining pressure in dense configurations. Second, the implementation of the SANISAND constitutive model validates these findings while extending the analysis to both monotonic and cyclic loading conditions. The model successfully captures sophisticated aspects of sand behavior, including the exceedance of vertical confining pressure by radial stresses while maintaining constant volume conditions. This dual approach provides unprecedented insights into stress evolution mechanisms during DSS testing, challenging traditional assumptions and establishing a robust framework for analyzing granular material behavior under simple shear conditions. The findings have significant implications for geotechnical engineering practice, particularly in applications involving cyclic loading and density-dependent soil response.

The Vagaries of Restorative Justice: Borders Between Restorative Justice and Justice as Punishment
Authors: Bulatović Aleksandra , Fatić Aleksandar
Published: January 2025

This paper explores the complex interplay between restorative justice and traditional punitive
justice systems. While proportional and rationalistic justice focuses on establishing some kind
of disturbed equilibrium between crime and a normal state of affairs in society, or on preventing
future crimes by increasing the costs of committing it for the offender, restorative justice
focuses on the actual restoration of the type of social capital that has been degraded by time.
Restorative justice thus works on healing and reconciliation, and tends to contrast sharply with
punitive justice, which emphasizes retribution and deterrence. One of the main obstacles to a
broad implementation of restorative justice is connected with community expectations. Most
communities have been habituated to expect punitive justice and have internalized these
expectations as their psychological way to achieve “closure” after a crime has victimized some
members of the community or, indirectly, the community as a whole. Thus one of the
challenges of modern restorative justice in practice is how to integrate it with more traditional
views on punitive justice, which is the preoccupation of this brief paper.
Exploring the Profiles of Drug Offenders in Croatia
Authors: Ćudina Vicko , Sokić Katarina , Sučić Ines , Barić Martina , Glavak Tkalić Renata
Published: January 2025

In Croatian prisons, there is a relatively high prevalence of offenders convicted for abuse of narcotic drugs (Art173/2, CC/97) who are heterogeneous in terms of their characteristics. Determining the relationship between the characteristics of those offenders and their behaviour before and during the execution of prison sentences helps predict their future behaviour. Therefore, this study aims to determine the profile of perpetrators of crimes related to the abuse of narcotic drugs, to investigate potential differences among subgroups of these perpetrators, and to examine whether they differ in the assessed risk for future criminal behaviour/probability of recidivism, penitentiary opinion on conditional release (CR), and Conditional release Committee decision on CR. We analysed penitentiaries’ reports with the opinion on CR for 111 male drug abuse offenders (Mage = 31; SDage = 6.51), containing rich data related to various offenders’ characteristics and behaviours. Specifically, we analysed offenders’ socio-demographic and anamnestic data, previous convictions, imposed security measures with sentence, proposed special obligations with CR, elements from the individual programs for the execution of prison sentence, mitigating and aggravating circumstances of committing the crime, positive reasons in prisoners’ application for CR, and penitentiaries’ explanations in support of the prisoners’ application for CR. The conducted cluster analysis did not show statistically significant differences between subgroups of offenders in the assessed risk for future criminal behaviour/probability of recidivism, penitentiary opinion on CR, and Conditional release Committee decision on CR, but there were low to moderate correlations between specific offenders' characteristics and these variables.

In this article, we discuss the effect of earth’s oblateness and magnetic force on the motion and stability of the system for elliptic orbit of the centre of mass. We have got a set of non-linear, non-homogenous and non-autonomous equations. Generally, a system moving in space has to face some perturbative forces. These forces compel the system to change its orbit from circular to elliptic orbit. On account of this we have studied in details the problem in elliptic orbit of the centre of mass. This is simply the generalization of the particular case of the Keplerian orbit i.e. circular orbit. So, we analysed the effect of the earth’s oblateness and magnetic force on the existence and behavior of different equilibrium position of the system. Also, discuss the Jacobian Integral of the averaged equations of motion of the system, Two equilibrium solutions of the problem and after Hooke’s modulus of elasticity.

Implementing the Reverse Acute to Chronic Workload Ratio Model to Improve Movement Capacity and Roster Availability: An Example Using Data from the NFL
Authors: Short Trevor , Yamada Paulette M
Published: January 2025

American football athletes require the development of workload capacity for repeated high-intensity efforts, and successful athletes are adept at accelerating, decelerating, and changing directions. The prescription of appropriate training volume stimulus can be difficult to determine, as there are very few guidelines for prescribing sport-specific acceleration, deceleration, and maximum velocity efforts. Preparatory training stimulus has to closely match in-game demands, but at the same time, practitioners need to avoid excessive workloads and undertraining to mitigate workload progression-related injuries and maximize roster availability. The acute-to-chronic workload ratio (ACWR) approach is based upon the fitness: fatigue ratio, which allows practitioners to monitor workloads.  New technology allows for in-game positional tracking and these advancements are accessible to the public. By measuring in-game movement, coaches can quantify key metrics like the number of accelerations and average distance covered. These metrics provide a snapshot of in-game demands and performance requirements. Using a reverse engineering approach, coaches can utilize ACWRs to calculate predefined targets to ensure athletes are adequately prepared for gameplay. Here we use the ACWR concept and previously reported in-game data derived from the National Football League to show how to reverse engineer the targeted number of efforts and distances to assist in preparatory pre-season training program design. This approach, which we term the Reverse ACWR Method, can be used to set guidelines for training volumes and workload progressions and provides a systematic, quantitative approach that complements periodization. As such, the Reverse ACWR Method allows practitioners to calculate target sport-specific workloads and training progressions derived from scientific-grounded methodology, which may enhance performance, readiness, and roster availability. Although this paper presents an example of how to use positional in-game data to prescribe American football training workloads, this model can be applied to any sport and team that has access to positional in-game movement data.

FREE TIME NORM AS A MEASURE OF SOCIAL WEALTH (CROSS-COUNTRY COMPARISON)
Authors: MINAT V.N.
Published: January 2025

The aim of the work is to empirically confirm the possibility of using the political and economic category of “free time norm” and public free time included in its structure to assess the level of social wealth. The level of the study covers cross-country comparison based on the ratio of elements of labor activity and free time of employed citizens of a number of countries. The methodological basis of this study is the definition of the free time norm and public free time by means of a mathematical relationship of the elements of productive and unproductive labor time, on the one hand, and the free time of society, on the other hand. Absolute (in hours) and relative (in percent) indicators allow us to establish the amount of labor costs and results in the context of ten social groups. The average annual number of the studied groups is determined based on national statistics, and the duration of the components of labor time and free activity is based on time budget data. The results of the empirical study showed the greatest appropriateness of an up-to-date assessment of social wealth from the position of the ratio of labor and consumption, excluding cost values. The diversity of the compared countries in their progress towards a reduction in the level of real wealth, reflected in the reduction in the share of socially free time as useful for personal development in the formation of human potential, is revealed.

Authors: Alharbi Mohammad Ali , Misnan Mohd Saidin , Abidin Nur Izieadiana
Published: January 2025

The construction industry in Saudi Arabia, like many developing countries, has a high rate of accidents, and MSMCs are disproportionately affected due to limited resources, a lack of expertise, and competitive pressures that prioritize cost reduction over safety. This research paper examines the challenges and opportunities faced by Micro, Small, and Medium Companies (MSMCs) in complying with safety regulations in the Saudi Arabian construction industry. The study employed a mixed-methods approach, combining quantitative data from questionnaires with qualitative insights from interviews with industry professionals. Quantitative analysis highlighted specific challenges, while qualitative analysis revealed the complexities and contextual factors contributing to these challenges. The study identifies 15 major occupational health and safety problems faced by MSMCs. These problems include a lack of skilled workers, employee constraints, communication gaps, reliance on temporary workers, high competition, limited access to external advice and support, constraints related to market share, time, and finances, limitations in business expertise, the absence of dedicated safety personnel on construction sites, low educational levels, employers’ lack of safety knowledge, a dearth of safety motivation and campaigns, and the tendency to prioritize profit over safety in project tenders. Poor communication, financial constraints, and the competitive nature of the industry, which pressures MSMCs to cut costs at the expense of safety, were identified as key challenges. The paper concludes by offering recommendations to address the identified safety challenges. These recommendations include developing targeted training programs, providing financial support for safety equipment and training, and fostering partnerships with larger firms to share safety resources.

Published: January 2025

The study was carried out to assess gender differentials in income diversification among farm households in Oyo state, Nigeria. A three-stage sampling technique was adopted to select one hundred and twenty respondents (120). Descriptive statistics, Mean of Income Shares, Simpsons Index of Diversity and Tobit regression model was used to analyze the data. The results show that, the average age of the respondents was 47.49 years, average household size is 7 and majority (74.36%) of household members were within 18-60 years of age bracket. The average farm size of the farmers is 1.94 ha and 68.4% had a minimum of primary school education. The mean farming experience was 12.34years while the average annual income of respondents is N113,170.83. Female respondents generated highest proportion of income (0.352) from Food Crop Production while male respondents generated highest proportion of income (0.383) from Cash Crop Production. Also, 90% of male respondents and 85% of female respondents embraced income diversification. The result of the probit model shows that age, number of households members >60 age bracket and education status all have negative coefficients which imply a negative probability relationship with the probability of income diversification. It does mean that any increase in any of these variables will leads to a decrease in probability of income diversification in among male farmers in the study area. However, household size, number of households members within 18- 60 age bracket and income has positive probability relationship with income diversification status of the male farmers. Again, household size, number of households members between 18-60 age bracket, farm size and income have positive probability relationship with income diversification status significantly influence the probability of income diversification among the female farmers.. The study concluded that the respondents’ socio-economic characteristics influences the degree of income diversification in the study area. It was therefore recommended that relevant stakeholders should introduce more gender specific enterprises.

Published: January 2025

As we know, all living things have direct or indirect relationships with each other. Some living things are alive that we cannot normally see with our eyes; that is, they have very small structures, but most of these living things have vital importance in our lives. This paper explores the complex and intimate relationships between certain microorganisms, such as plants, bacteria, and fungi, to include the relationship between mycorrhiza, nitrogen-fixing bacteria, and host mortality. It also highlights the importance of these relationships in nutrient cycling, stress tolerance, and disease resistance. The effects of these relationships on plant fitness and community structure, as well as the complex signaling pathways that control them, are also being studied. However, it emphasizes the importance of understanding such interactions for sustainable agriculture and ecosystem conservation, as well as harnessing these associations to promote resilient and sustainable global ecologies. The microbial plant association is a huge and ever-changing field, ready for scientific exploration. Therefore, this abstract is a call for better understanding to discover hidden features of the life dance, which can help us make our plants healthier and our agriculture practices more sustainable.

YTTRIUM AS A MODIFIER IN CATALYSTS FOR SULFUR REMOVAL AND IMPROVED STABILITY
Authors: B. Yamaltdinov
Published: January 2025

This study delves into the use of yttrium-modified catalysts in hydrotreatment processes, focusing on how they enhance sulfur removal efficiency and improve catalyst stability. By introducing yttrium into various catalyst systems, such as palladium-platinum (Pd-Pt) supported on Y-modified USY zeolite and Y-doped Ni₂P phosphides, researchers observed significant advancements in catalytic performance. These included better removal of hard-to-treat sulfur compounds like 4,6-dimethyldibenzothiophene (4,6-DMDBT), improved dispersion of active metals, and fewer strong acidic sites, which collectively reduced coke formation.
The study emphasizes yttrium’s unique ability to tackle persistent challenges in hydroprocessing, including the removal of refractory sulfur compounds that conventional catalysts struggle to address. Additionally, yttrium enhanced the structural and operational stability of the catalysts, minimizing coke buildup and maintaining efficiency during extended use. Combining experimental findings with theoretical insights, the research positions yttrium as a pivotal modifier for developing next-generation catalysts capable of achieving ultra-deep desulfurization.
These catalysts not only meet stringent environmental standards but also demonstrate excellent durability, making them ideal for industrial applications, particularly in diesel fuel hydrotreatment. Future work will focus on refining yttrium incorporation methods and scaling these advancements for widespread industrial adoption.

В исследовании изучен полиморфизм генов CSN3, LEP и LALBA и их связь с молочной продуктивностью и воспроизводительными способностями коров красной степной породы, разводимых в степной зоне Сибири. Установлены частоты генотипов: CSN3AA (41,0 %), CSN3AB (44,0 %), CSN3BB (15,0 %); LEPCC (31,0 %), LEPCT (45,0 %), LEPTT (24,0 %); LALBAAA (39,0 %), LALBAAB (50,0 %), LALBABB
(11,0 %). Генное равновесие не нарушено (χ2 = 0,308–0,930). Генотип LEPTT ассоциирован с повышенным содержанием жира в молоке в первой лактации (на 0,06–0,07 %) и белка во второй (на 0,11 %), а также сокращением сервис-периода на 34,7 дня по сравнению с LEPCC. Генотип LALBAAA обусловил увеличение удоя в первой лактации на 624,5 кг, а также повышение содержания белка на 0,06 %. При этом у коров с LALBAAA наблюдалось снижение содержания жира в третьей лактации на 0,07 %. Выявленные корреляции генотипов с продуктивными признаками подтверждают их значение для селекции. Результаты требуют дальнейшей проверки на расширенной выборке, однако представляют потенциальную ценность для совершенствования племенной работы.
Ключевые слова: красная степная порода, ген, генотип, удой, воспроизводительные способности.

В данной статье рассматривается влияние сезонных сточных вод реки Иртыш и проанализированы основные показатели загрязняющих веществ, также рассмотрена принципиальная технологическая схема очистных сооружений г. Павлодар. Сброс сточных вод с очистных сооружений сточных вод оказывает серьезное пагубное воздействие на здоровье водных экосистем. Рассмотрен ежеквартальный контроль за качеством вод реки Иртыш по основным створам контроля: вход в область (в районе села Подпуск и села Акку), на протяжении области, выше и ниже сброса городских очистных сооружений, выход из области (с. Прииртышское). Также важно заметить, в статье проанализированы в каких сезонных периодах связанное с увеличением нагрузки деятельности промышленных и хозяйственно – бытовых предприятий (АЗС, химчистки, бани и сауны и т.д.). Это в свою очередь приводит к увеличению концентраций тяжелых химических металлов: цинка (Zn), железа (Fe), а также нефтепродуктов. Промышленные сточные воды загрязняют водоемы токсичными химическими веществами, что приводит к ряду изменений в их характеристиках. Это включает изменение органолептических свойств воды, таких как цвет, вкус и запах, замедление или полное прекращение процесса самоочищения водоемов, а также нарушение природного баланса. Растворенный кислород в воде уходит на дно, оседают отложения, снижается численность планктона, что негативно сказывается на рыбе, особенно в весенне-летние и осенние месяцы.
В этот период наблюдается превышение концентрации химических веществ, что связано с усиленной деятельностью промышленных и бытовых предприятий

La Bioética es un campo de trabajo interdisciplinario propuesto por Van R. Potter en la década de 1970. Se caracteriza por su orientación hacia la supervivencia de la especie humana y su reconocimiento de la existencia de valores naturales objetivos que permiten vincularla con el discurso de la sustentabilidad. Por ello, la Bioética se presenta como una opción para trabajar la dimensión ética de la educación para la sustentabilidad. Los cursos de Ética, sin embargo, no son la única opción para transformar las actitudes y los valores de los educandos. En este artículo, se aborda la importancia de enfocarse en construir espacios de convivencia en los que puedan ponerse en práctica de manera cotidiana los hábitos y los valores que consideremos virtuosos, en este caso, desde la perspectiva de la bioética y de la sustentabilidad.
Reconfiguración pedagógica pospandemia: exploración de la incidencia de la pandemia en métodos de enseñanza universitaria

Published: January 2025

Durante la emergencia sanitaria, reconfiguramos aspectos pedagógicos y adaptamos tiempos, espacios y contenidos mediante el uso de tecnologías para mantener la enseñanza. En la actualidad, atravesamos un entrecruzamiento de espacios presenciales, sincrónicos y asincrónicos, mediados por plataformas digitales que potencian la retroalimentación, el diálogo y el aprendizaje colaborativo.Este trabajo explora la transformación de la educación superior en la era pospandémica mediante una metodología que incluye encuestas a docentes de la Universidad Nacional de La Plata y observaciones sobre clases híbridas. Las encuestas, realizadas a docentes de las carreras de Comunicación Social y Bibliotecología, relevan su adaptación a las tecnologías, los retos y las oportunidades percibidas, así como la incidencia en la interacción con estudiantes. Los resultados indican que la emergencia sanitaria actuó como un catalizador para la articulación de modelos híbridos y la gestión adecuada de la crisis para transformarlas en posibilidades, y se concluye que las metodologías híbridas pueden promover la educación y acompañar la integralidad en esta nueva era.

Los ecosistemas relacionados con el agua aportan importantes beneficios económicos y sociales en todos los países por lo que su protección se ha convertido en prioridad estratégica. Particularmente en Cuba, la disponibilidad de agua representa un gran desafío para lograr el desarrollo económico y la seguridad alimentaria. Esta investigación realizó un estudio de la variación espacio temporal de los principales embalses de la provincia Mayabeque durante los años 2000 al 2020, tomando como línea base el quinquenio 2000 – 2004. Fue aplicada la metodología aprobada por la Organización de Naciones Unidas para el seguimiento del indicador 6.6.1 de los Objetivos de Desarrollo Sostenible. Se emplearon los índices espectrales MNDWI y AWEIsh calculados de las imágenes satelitales Landsat 5, 7 y 8. Los resultados mostraron marcada tendencia a la disminución de las áreas de los embalses analizados lo cual se corresponde con el comportamiento del clima en Cuba en las últimas décadas y señala la necesidad de lograr una gestión integral y sostenible del agua que no comprometa la integridad ecológica de las cuencas y la respuesta a la creciente demanda de este recurso vital.Palabras claves: variación espacio temporal, teledetección, índices MNDWI y AWEIsh, ODS 6.6.1.
