Background: The mucosal epithelial barrier, the first line of immune defense, is vulnerable to allergens, pathogens, and inflammatory cytokines, contributing to CRS development. Our previous studies found high interleukin-17A(IL-17A) expression correlated with CRS severity and low glucocorticoid efficacy. The role of IL-17A in disrupting the nasal mucosal epithelial barrier leading to CRS remains unclear. We aimed to investigate how IL-17A promoting epithelial barrier damage and identify new treatment targets for CRS. Methodology: Nasal tissue samples from 36 CRSwNP, 34 CRSsNP, and 39 controls were examined for the expression of IL-17A and tight junction (TJ) proteins using qRT-PCR, immunohistochemistry and immunofluorescence. The integrity of TJs and signaling pathways activation were observed using western blot, immunofluorescence, TEER and FITC–FD4, transmission electron microscopy before and after IL-17A stimulation in human primary nasal epithelial cells (hNECs). Concurrently, studies were also conducted in an CRS mouse model induced by anti-IL-17A neutralizing antibody administration. Results: TJs expression in the nasal mucosa of CRS patients was lower than in controls. IL-17A stimulation reduced TJs expression and TEER while increasing hNECs permeability. Inhibition of the (ERK/STAT3) pathway reversed the downregulation of TJs and the disruption of the epithelial barrier induced by IL-17A stimulation. In the CRS mouse model, anti-IL-17A antibody treatment rescued the nasal mucosal epithelial barrier. Conclusions: IL-17A disrupts the nasal mucosal epithelial barrier by activating the ERK/STAT3 pathway in patients with CRS.

Published: October 2024

The previous decade, from a global point of view, was characterized by a significant paradigmatic change when it comes to sustainable development policies. In many countries, and especially in Europe, more than ever the focus is on the local level of action, and not only in the domain of local development policies and strategies, but much more deeply at the level of details of planning and designing and building human settlements. At the root of these paradigms is a deep process of scientifically based re-examination of the meaning of the idea of sustainable development, and accordingly the purposes and roles of the discipline of architecture in achieving sustainable development of settlements. This is the reason for the intensification of activities in the field of formulating architectural policies, strategies and paradigms in the European Union, including Serbia, which is in the process of joining. Paradigmatic change within the science of sustainability implies social transformation and redefinition of the social role of architecture and the architectural profession, innovating knowledge and approaches to practice in the area of settlement planning and managing the development of the built environment. The success of this kind of social transformation must be based on the specifics of the local context, but also on the current development processes of the wider region and the global world. National architectural strategy of the Republic of Serbia 2025-2035. is a strategic document that aims to articulate this complex process of social transformation in Serbia, with the aim of creating conditions for qualitative change in accordance with the conscious localization of the sustainable development goals of the 2030 Agenda. However, the success of its implementation depends on social capacities for understanding, acceptance and proactive action towards change. This chapter aims to create a framework for a realistic critical view and understanding of the approach to defining architectural policy in Serbia through an integrated and multi-layered analysis. The result is the systematization of knowledge, a kind of cognitive framework that aims to orient and encourage the actions of very different professional and scientific profiles of architects towards the sustainability of settlements in Serbia – the common value of the human community, not only in this territory but also globally.

The Ministry of Mining and Energy of the Republic of Serbia has issued around 200 exploration rights for various mineral resources, covering approximately 6% of the national territory, encompassing 536,000 hectares. These exploration rights predominantly pertain to gold, lithium, boron, silver, copper, nickel, and antimony reserves. The seekers of exploration rights are mainly private mining companies registered in Serbia, either as subsidiaries of global mining corporations or domestic companies. Exploration areas in certain regions of Serbia range from 50 to 150 km² and are located in stable agricultural and forest areas (the Jadar and Rađevina valleys; Levač; Šumadija; Homolje). The potential issuance of exploitation rights for the excavation and processing of ores implies the application of complex chemical-technological processes involving the use of large quantities of aggressive and highly toxic substances (sulfuric, phosphoric, and hydrochloric acid, sodium cyanide), which carry a significant risk of soil, water, and air pollution, endangerment of living organisms, and deterioration of public health indicators for the local population. Besides the physical destruction of tens of thousands of hectares of arable land and forest areas, the possibility of intensive agricultural production and the survival of local communities would be significantly compromised, thus affecting the identity and cultural values of certain parts of Serbia. Simultaneously, the untapped potential of Serbian agriculture, besides material benefits, could provide complete security in producing quality food, prosperity in rural areas, and overall growth in all economic development indicators, is being neglected. A strategic, structural reassessment of Serbia’s financial model is necessary to objectively evaluate achieved results and define the goals of economic sovereignty based on sustainability and full respect for public interest.

This paper is prepared on activities and some of the results of the COST Action CA18110 project – “Underground Built Heritage as Catalyser for Community Valorisation” (Underground4Value – U4V) (2019-2023). The action brought together more than 200 experts from 32 countries. Underground Built Heritage (UBH) is a unique cultural resource, being a focus of many recent scholarly papers from the fields of conservation, tourism, economy, IT, and others. Natural and human-made caves, underground burial sites, mines and quarries, other human-made caves used for habitation and work, subterranean infrastructures (cisterns, tunnels, ancient drainage systems, etc.), and ancient buried structures and settlements are all examples of the UBH site typologies. They represent very attractive cultural and tourism resources not only for foreign visitors but also for the local community and domestic visitors. Additionally, such sites are often located in the cities or their surroundings, which makes them accessible and suitable for daily visits. Therefore, research on UBH requires an interdisciplinary approach, various techniques, and methodologies. The main goals of the U4V project promote UBH as a valuable resource to preserve and promote sustainable (re)use of cultural heritage, and to valorise its full potential to support local community development. To achieve this overall challenge, the project focuses on managing and treasuring the wide participants’ competencies to identify key areas of scientific, technical, commercial, managerial, political, cultural, and social nature, which are currently perceived as problematic for sustainable use of UBHs. Project partners are interacting with local communities, disseminating innovative thinking, and supporting them to explore alternative social trajectories, such as establishing Living Labs, and experimenting with transition management tools. The main results of the project focus on developing new skills for planners, decision-makers, promoters, and local development facilitators, as well as networking partners from different European and other countries in-situ, online, and on digital platforms.
PLANNING SUSTAINABLE MOBILITY FOR SERBIAN CITIES: INSIGHTS FROM THE FRENCH EXPERIENCE
Authors:   RATP Group, Paris, France, Voisin Mathieu
Published: October 2024

This report addresses the topic of implementing mobility strategies in Serbia by sharing insights from the 40-year-long experience in France. The first part emphasizes the need to set up policies by presenting the impacts of the transport sector on national energy consumption, public health, households’ income and the organization of urban mobility in France. It recalls the national and international objectives to meet in order to mitigate climate change and it explains how shifting to shared and decarbonated mobility solutions can also create opportunities for local economy and territorial development. Eventually, it proposes a new paradigm in which cities and transport networks are designed together to fit one to the other. The second part explains the core content of mobility strategies, whether they address major metropolises, medium cities or rural settlements. Attention is paid to the main methodological steps to follow, on how to build an inclusive approach with citizens, on how to work proactively with all stakeholders and how to implement an enforceable document. The last part of the report explains the respective roles of the State, the Regions and the Local Authorities in implementing mobility strategies through a long-term decentralization process and incremental evolutions of the legal framework. It then describes the content of major French mobility planning tools such as the Urban Mobility Plan (Plan des Déplacements Urbains), which enabled the implementation of comprehensive public transport networks in major metropolises, and it describes its recent evolution towards new tools such as the Mobility Plan (Plan de Mobilité) and the Simplified Mobility Plan (Plan de Mobilité Simplifié) which focus on decarbonated modes, adequacy to the territorial context and coordination between local Mobility Authorities. Based on insights from the French National Observatory for Mobility Strategies and outcomes from official planning documents of the Republic of Serbia, possible transpositions from the French experience to Serbian cities are also proposed.

In a modern educational context, educational software is becoming a key tool for enhancing mathematics teaching. Our study explores the effects of implementing such software on students’ achievements. The motivation for this research stems from the results of the PISA testing, which indicated below-average knowledge among our students. An analysis of factors influencing student achievements was conducted using the Adaptive Neuro-Fuzzy Inference System (ANFIS) method, confirming the importance of educational software in improving students’ mathematical skills. Subsequently, an experiment was conducted over three school years, involving two groups of students. The first, experimental group utilized educational software as the primary tool for learning mathematics, while the second, control group continued with traditional teaching methods. Through carefully designed experimental protocols, data on student achievements were collected via various mathematics knowledge tests, as well as their satisfaction with both traditional teaching methods and interaction with the software. The research results demonstrate that students using educational software achieve significantly better results on mathematics knowledge tests and are more satisfied with their learning compared to the group taught using traditional methods. This study highlights not only the positive impact of educational software on mathematics achievements but also the need for further research and practice in integrating technology into teaching to achieve optimal educational outcomes.

ВЛИЯНИЕ ИЗМЕНЕНИЯ КЛИМАТА НА ЕСТЕСТВЕННЫЕ РЕСУРСЫ ПОДЗЕМНЫХ ВОД ЦЕНТРАЛЬНОГО ВУЛКАНИЧЕСКОГО НАГОРЬЯ РЕСПУБЛИКИ АРМЕНИЯ

Питьевое водоснабжение Армении в основном осуществляется за счет высококачественных подземных вод вулканического нагорья. За последнее десятилетие наблюдается постоянный спад расхода родников, который обусловлен уменьшением осадков. Главную роль в формировании подземных вод играют осадки в зоне питания – на абсолютных отметках свыше 2500 м. Формирование подземных вод происходит в трещиноватых вулканических породах, а накопление и движение – в погребенных речных долинах. Различными научными и политическими организациями разработаны модели по прогнозу изменения климата по различным сценариям (МГЭИК, METRAS), которые различными обществеными организациями использовались для моделирования изменения климата до 2100 г. для территории Армении и опубликованы в виде национальных сообщений. Сравнительный анализ полученных в работе данных с докладами МГЭИК показал, что прогнозы различных сценариев МГЭИК не достоверны. А в прогнозах METRAS указано, что нехватка фактического материала усложняет точность расчетов. Глобальное изменение климата приводит к уменьшению расходов подземных вод Армении и, в частности, подземных вод Центрального вулканического нагорья. Для нахождения зависимости между осадками в области питания и расходом родниковых вод в области разгрузки рассчитано приблизительное время движения подземных вод от зоны питания до зоны разгрузки на примере Арзаканских родников, где расстояние между ними составляет 24 км, а расчетное время – 6,5 лет. Установлено, что с 2013 г․ по 2023 г․ расходы родников уменьшались по линейной зависимости, а уменьшение расхода составляет 24–33%. Изменений химического состава родниковых вод от уменьшения расходов не установлены, кроме сульфат-иона, концентрация которого увеличивается с увеличением расхода родников. Требует дальнейших исследований предположение о том, что повышение содержания сульфат-ионов может служить предвестником увеличения расхода родников. По результатам исследований предполагается, что по количеству осадков в высокогорной зоне возможно обоснованно прогнозировать изменения расходов подземных вод для исследуемых родников на 6–7 лет вперед.
СОСТОЯНИЕ ИЗУЧЕННОСТИ ВОХЧАБЕРДСКОГО ОПОЛЗНЯ

Published: October 2024

Вохчабердский оползень является одним из нескольких крупных сейсмогравитационных оползней, приуроченных к зоне сейсмически активного Гарнийского разлома. Он представляет собой блок размером 2,5–2,8 км2 и предполагаемой мощностью в среднем 70–80 м, сорванный с крутого склона одноименного хребта и сместившийся по линии разлома взбросового характера. На сегодняшний день по Вохчабердскому оползню имеется определенный объем фактического материала (его происхождение, ряд внешних параметров, характер активности, положение грунтовых вод, причиняемые им разрушения сельских строений и автомобильной дороги и др.). Однако отсутствуют достоверные данные по мощности оползневого тела, что не позволяет определить наиболее подходящие для данного участка противооползневые мероприятия. Необходимы капитальные мероприятия для полной остановки смещений оползневой толщи. Для выяснения мощности оползня необходимо пробурить хотя бы 3 скважины по его длине, но обязательно довести бурение до поверхности скольжения.
ФОРМИРОВАНИЕ И РАЗВИТИЕ СКЛОНОВ ВУЛКАНИЧЕСКИХ СООРУЖЕНИЙ АРМЯНСКОГО НАГОРЬЯ
Authors: Бойнагрян Владимир Р.
Published: October 2024

В статье выявлены особенности вулканических склонов Армянского нагорья с учетом того, что их формирование и развитие происходило в условиях относительного дефицита влаги (за исключением высокогорного пояса). Последние в научной литературе освящены довольно скудно, поэтому исследования автора в какой-то мере восполняют имеющийся пробел. Вулканический рельеф с соответствующими склонами сформировался здесь в основном в плиоцен-четвертичное время и относится к так называемому Армянскому вулканическому нагорью. Формирование и развитие вулканических склонов нагорья имеет ряд особенностей: относительная молодость; быстрое их формирование, опережающее во много раз темпы выветривания вулканогенных пород; состав пород (лавы, пирокластический материал), что имеет существенное значение в образовании склона определенной морфологии; водопроницаемость вулканогенных пород; промежуточный базис денудации для большинства вулканических склонов. Склоновый чехол на большинстве вулканических склонов нагорья в целом находится на начальной стадии формирования. Преобладают в основном базальный горизонт и, реже, морфодинамический. Покровный горизонт встречается преимущественно в нижней, более пологой части склона. На нагорье параллельное отступание склонов без значительного выполаживания отмечается у краев лавовых потоков и плато, которые непосредственно обрываются к руслу реки, а последняя успевает удалять обвалившийся материал. Параллельное отступание в этом случае облегчается наличием у лав столбчатых отдельностей.

Землетрясения являются одним из опасных природных явлений, которые невозможно в точности прогнозировать, вследствие чего они в настоящее время относятся к ряду недостаточно изученных. Причиной их возникновения являются сложные геологические и тектонические процессы, протекающие в недрах Земли. Мгновенно высвобождаемая энергия в очаге землетрясения проявляется в виде сейсмических волн, приводящих к разным видам деформаций и смещений в земной коре, зачастую меняющих форму и облик рельефа. К сожалению, подобного рода сильные землетрясения сопровождаются большими разрушениями и огромными человеческими жертвами. К подобным мощным землетрясениям можно отнести два землетрясения, произошедшие 06.02.2023 в Турции, имевшие катастрофические последствия и повлекшие за собой многочисленные человеческие жертвы. По мере развития науки и технологий все больше различных инструментов и методов становятся более доступными для изучения природных явлений. Одними из таких методов являются космические геофизические методы и инструменты изучения атмосферы и земной поверхности. Дистанционное зондирование Земли нашло широкое применение в вопросах качественного, количественного изучения и анализа процессов, протекающих в земной коре и отраженных на поверхности Земли. Данная работа посвящена исследованию одному из таких процессов. В частности, на сегодняшний день широкое применение имеет дистанционный метод исследования Земли с использованием радиолокационной аппаратуры на борту искусственных спутников. Современные радары синтезированной апертуры дают широкие возможности для изучения малейших деформаций и смещений рельефа земной поверхности, а также техногенных объектов. В рамках данного исследования лежит техника интерферометрической обработки InSar данных радиолокационных снимков спутников Sentinel-1. На основе дифференциальных интерферограмм составлены карты смещений исследуемой области, выраженные в долях метра.

Authors:   Institute of Engineering and Technology, Thu Dau Mot University, Binh Duong Province, Vietnam, Thu Hien Nguyen Thi
Published: October 2024

Saanen is a specialized dairy goat breed originating from Switzerland, imported and encouraged to be raised in Vietnam. This article presents the results of a survey of estradiol and progesterone levels during pregnancy in Saanen goats at the Binh Duong Large Livestock Research and Development Center. After monitoring mating, goats were sampled for blood every 7 days until birth, at 6-8 am. Hormone levels were determined by electrochemiluminescence assay, with the Cobas E601 immunoassay system. The results showed that after 14 days of conception, progesterone levels gradually increased (3.21±0.36 ng/ml) and shifted to higher levels, peaking on day 70 of pregnancy (12.28±0.52 ng/ml) (in the 1-2 years old group); corresponding values were 3.18±0.75-11.88±0.92 ng/ml (in the 3-4 years old group). The high value range was maintained throughout pregnancy and decreased rapidly in the 14-21 days before birth in both age groups. Estradiol, maintained at low concentrations from 0.73±0.35 to 2.65±1.25 pg/ml (in the 1-2 years old group); from 0.98±0.48 to 3.27±1.95 pg/ml (in the 3-4 years old group) in the first 21 days of pregnancy and then gradually increased to above 10 pg/ml (in both age groups) on day 28. Estradiol continued to increase and reached a maximum level (205.48±32.81 pg/ml) in group 1 on day 126 and had an average value below 10 pg/ml within 1-2 days after giving birth. The results of this study help diagnose pregnancy, predict gestational age for effective reproductive management, and serve as a reliable reference when using assisted reproductive tools and strategies to improve reproductive performance in goats.

Published: October 2024

There is an observed general low performance of Ethiopian Sport Governing Bodies (SGBs) in service delivery. Evidence shows that the trend can be corrected with proper understanding and insight into the process of organizational and management factors of these SGBs. This study aimed to investigate the contribution of organizational and management factors as determinants in effective service delivery in SGBs. For this study, a cross-sectional research design was employed. Purposive sampling was used to choose 350 samples from 154 internal and 196 external stakeholders. The instruments used for the study were the key informant interview and the questionnaire. Pearson Product Moment Correlation Coefficient and multiple regression were used to analyze the data at the 0.05 significant level while qualitative data were content analyzed. The findings confirmed that organizational and management factor variables had a significant positive relationship with sport service delivery (organizational structure (r=0.515), organizational capabilities (r=0.701), communication (r=0.549), management practice (r=0.571), materials & resources (r=0.527) and stakeholders satisfaction (r=0.742). Management factors jointly predicted effective sport service delivery (F (3, 329)= 165.868, R2= 0.612); organizational factors had a joint significant contribution to effective sport service delivery (F(3, 329) = 148.743, R2= 0.576). Further, organizational and management factor variables had a joint relative significant influence on effective sport service delivery in Ethiopian SGBs (F (6, 326) =130.81, R2= 0.707). Interviews revealed that there are weak relations with stakeholders, an unaligned structure of regional sport bodies with federal bodies, and managers with improper experience and knowledge in sport which influences effective sport service delivery in Ethiopian SGBs. Therefore, working together with stakeholders, structural advancement, designing rules and regulations that can serve a longer time, taking correction based on feedback from stakeholders, networked structures and collaborations with local sports organizations as means of improving service delivery employing shared burden and coordinated effort are recommended.

Published: October 2024

The primary objective of this research was to assess the impact of a structured physical activity program on the health indicators of adult students attending a multicultural Second Chance School (SCS). The study encompassed a total of 62 SCS students aged 19 to 57, who were divided into two groups: experimental and control. The intervention program consisted of two sessions per week spanning 20 weeks, with each session lasting 60 minutes. The exercise intensity ranged from 65% to 85% of HRmax and included various activities such as aerobics, weight exercises, dumbbell routines, and hiking. Measurements were taken at both the commencement and conclusion of the organized physical activity program. Specialized equipment, including a wall-mounted stadiometer, precision scales, a unique tape measure, an automated sphygmomanometer, and the DXA machine, was employed for data collection. Data analysis involved ANOVA variance analyses, descriptive statistics, and T-Tests utilizing the SPSS software. The results revealed a statistically significant primary influence attributed to the 'measurement' factor (p<.001) across all health indicators, except for total BMD and total BMC, when comparing the experimental and control groups. In terms of gender disparities, men exhibited higher measurements in body mass, fat-free mass, belly size, and blood pressure, while women displayed greater fat mass and total body fat. To conclude, the intervention program had a positive impact on improving the health indicators of adult SCS students. Future research endeavors should explore the implementation of Physical Activity programs in other SCSs throughout Greece.

Published: October 2024

Many women experience dysmenorrhea, which affects their daily activities due to physical and psychological symptoms. This study aims to analyze the impact of an ideal body mass index (BMI) and physical fitness level on reducing dysmenorrhea. An experimental research approach with a control group pretest-posttest design was employed. The study involved 92 female students, with a final sample of 80 divided into high and low-fitness groups. Participants were selected through purposive sampling, ensuring they had an ideal BMI, regular menstrual cycles, and experienced dysmenorrhea. Data collection included questionnaires on demographics, BMI, menstrual characteristics, pain intensity, pain quality, and a 2.400 m Cooper physical fitness test. The results revealed that participants with an ideal BMI and high physical fitness showed a significant reduction in dysmenorrhea, with an average decrease of 35,95 and a standard deviation of 4,681. Those with an ideal BMI but low physical fitness also experienced a reduction, with an average decrease of 31,4 and a standard deviation of 1,827. The study concludes that ideal BMI and physical fitness significantly influence the reduction of dysmenorrhea, with a more pronounced effect in those with higher physical fitness levels. Factors such as BMI, diet, and exercise routine are critical in managing dysmenorrhea.

El ejercicio es una de las intervenciones no farmacológicas más prometedoras de la actualidad para prevenir o reducir el deterioro cognitivo asociado con enfermedades neurodegenerativas o el envejecimiento. El objetivo de este estudio fue determinar el efecto de un programa de entrenamiento funcional de alta intensidad (HIFT) sobre la calidad de vida, calidad del sueño, estabilidad y niveles de depresión en una población colombiana de adultos mayores con deterioro cognitivo leve (DCL). Para esto, se llevó a cabo un ensayo clínico controlado aleatorizado con una muestra de 162 adultos mayores con DCL. El grupo intervención (GI) recibió tratamiento con HIFT por 12 semanas 3 veces a la semana, mientras que el grupo control (GC) recibió recomendaciones generales de actividad física y realizó actividades manuales. Se observó que, posterior a la intervención, hubo una mejora significativa en el GI comparado con el GC en la calidad de vida en múltiples dominios (p < 0,05), calidad de sueño (p < 0,001), estabilidad postural (p < 0,001) y depresión (p < 0,001). El análisis de covarianza multivariada mostró la influencia de la edad y los niveles de deterioro cognitivo (MMSE) sobre los resultados. Este estudio demuestra que la implementación de un programa corto de HIFT tiene un efecto positivo sobre la calidad de vida, calidad del sueño, estabilidad y niveles de depresión en adultos mayores con DCL.

The development of technology has revolutionized the world of education. Augmented Reality (AR) is one of the media that is starting to be developed for the learning process. AR has become a potential tool to improve the learning process among children. This study aims to systematically review previous research related to the application of AR to develop students' gross motor skills in early childhood education. The data collection process was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method which was adapted in this study. Identification results from five databases (SCOPUS, Pubmed, OpenAlex, Google Scholar, and Crossref) obtained 2807 publication documents. Bibliometric analysis was conducted on 1938 eligible articles, and 10 articles were selected as a literature review. The results of the bibliometric analysis showed less significant results on AR research in developing early childhood motor skills. However, overall AR research in early childhood education has experienced significant development. More attention and focus is needed regarding the development of early childhood motor skills research through the integration of AR technology. Thus, AR research in early childhood education is not limited to cognitive, but also focuses on motor skills as well.

Cyperus rotundus Linn is a plant that is historically used in traditional medicine with anti-cancer potential. Despite the evidence of C. rotundus anti-cancer effect on various human carcinoma cell lines, its pharmacological mechanism remains unclear, particularly its non-polar fraction. This study was employed to provide mechanistic insight regarding the anti-cancer properties of C. rotundus non-polar fraction by integrating in silico and in vitro approach. The network pharmacology study was used to observe the molecular targets of n-hexane fraction of C. rotundus, confirmed by molecular docking simulation using Autodock 4.2. The in vitro toxicity using BSLT method was used to strengthen the in silico result. The network pharmacology investigation revealed several core targets including PI3K, MAPK1, mTOR, RAF1, and NF-κB in the potential anti-cancer mechanism of C. rotundus. The molecular docking study illustrated that compound 3 (Isopetasol) and compound 9 (alpha-cyperone) as the most promising compound in n-hexane fraction of C. rotundus, with free binding energies consistently less than -7 kcal/mol in all targets. The in vitro BSLT signified the in silico results, highlighting the highest toxicity of fraction 3 exhibited among others. Integrating the network pharmacology and molecular docking simulation along with in vitro toxicity have provided evidence of the anti-cancer potential of n-hexane fraction of C. rotundus. Specific compounds and the molecular targets responsible for its anti-cancer properties have been identified, warranting further investigations.

Published: October 2024

An intensive study on structural, electronic mechanical and optical properties of bulk Niobium
Dichalcogenides NbX2 (X=S, Se) was carried out using the first principle. The structural
parameters such as Equilibrium Lattice Parameters, Volume, Bulk Modulus, and FirstDerivative Modulus were calculated to determine if the materials are energetically stable.
Elastic constants were further obtained from which mechanical properties i.e. bulk, Young's
and shear moduli and consequently Poisson's ratio were obtained. Based on the well-known
Born stability conditions Bulk-NbS2 is most likely mechanically anisotropic ductile material.
While Bulk-NbSe2 for the predicted B/G ratio in all three methods is less than a critical value
of 1.75, hence this shows that NbSe2 is a brittle material exploring its electronic and optical
properties whose motivation was to find out the most stable phase and ascertain if these
materials could be used in various fields that suit their mechanical and optical properties.
Furthermore, from the calculated optical spectra, plasma frequencies were analyzed which
indicated the possibility of applying the material in plasmonic-related fields.

This research study investigates language teachers’ perspectives on the influence of TechSpeak (or TxtSpk) on second language learning and writing skills among students in the College of Education at Central Mindanao University and Bukidnon State University during the second semester of the 2021-2022 academic year. The study aims to 1. identify the common TechSpeak language used by students in academic writing; 2. assess the impact of TechSpeak on students’ second language learning and writing skills; 3. uncover themes and patterns from teachers’ perspectives on TechSpeak. The study involved six language instructors—five females and one male—selected through purposive sampling from both universities. Individual interviews were conducted, focusing on their experiences and observations regarding students’ submissions and feedback. Analysis of the data led to several key themes regarding the impact of TechSpeak. First, TechSpeak affects students’ formal writing, confirming earlier research on the intersection of technology and learning. While students demonstrate an understanding of appropriate TechSpeak usage, its frequent use in formal contexts raises concerns about its potential negative impact on writing skills. The prevalence of TechSpeak, characterized by abbreviations, acronyms, and omissions, suggests an emerging trend that may hinder formal writing capabilities. To mitigate the adverse effects of TechSpeak. educators and parents should promote awareness of the importance of proper spelling, grammar, and punctuation across all forms of communication. Students should be actively encouraged to distinguish between informal and formal writing contexts and adjust their language accordingly. Further research is needed to investigate the long-term impacts of TechSpeak on writing skills and to develop effective strategies for addressing its use within educational settings.

Implementing IFRS 9 in Nigeria brought with it both opportunities and challenges to the banking industry which require a thorough analysis. A lot of questions remain unanswered on how the implementation of IFRS 9 impacts banks’ bottom lines. This study aimed to assess how the adoption of IFRS 9 has affected the financial performance of Nigerian deposit money banks. The impact of the introduction of IFRS 9 on the performance of the DMBs in Nigeria was investigated by analyzing financial performance metrics, including return on assets (ROA) and return on equity (ROE). The study used Access Bank Limited (ACL), Guaranty Trust Bank Limited (GTB), United Bank for Africa Limited (UBA), and Zenith Bank Plc (ZB) as a case study. A paired sample t-test was used to analyze the data from the banks’ financial reports for the five years before and after the adoption of the standard. The results implied that different banks saw different effects from the implementation of IFRS 9. Stability was shown by ABL while UBA showed a significant rise in both ROA and ROE, demonstrating successful planning and transition tactics. Major changes occurred at GTB and ZB, highlighting the significance of strategic financial planning and strong risk management frameworks in sailing through the challenges brought about by IFRS 9. According to the findings, Nigerian DMBs’ ROA and ROE are significantly impacted by the standard’s implementation. The study recommends that banks should maintain a proactive approach to monitor and adjust their financial strategies and operations accordingly given the ongoing evolution of accounting standards and regulatory requirements.

Published: October 2024

Tourism is a vital economic driver for many countries, including Malaysia, where it significantly contributes to GDP, employment, and cultural exchange. However, the rapid expansion of tourism, combined with the escalating impacts of climate change, poses serious threats to the sustainability of tourist destinations in Malaysia. Climate change, manifesting in rising sea levels, extreme weather events, and biodiversity loss, directly affects the natural and cultural assets that attract tourists. Concurrently, over-tourism exacerbates these challenges, leading to environmental degradation, resource depletion, and social conflicts due to the influx of visitors that exceed the carrying capacity of destinations. The aim of this study is to examine the combined impacts of climate change and over-tourism on diverse tourism destinations in Malaysia, including coastal, urban, and highland areas, and to evaluate the current strategies and policies in place to mitigate these impacts. The findings of the study reveal that the intersection of climate change and over-tourism creates a feedback loop, where environmental degradation reduces the quality of the tourist experience and threatens the socio-economic stability of local communities dependent on tourism. This study highlights the need for more integrated management approaches that align sustainable tourism practices with climate adaptation strategies to enhance the resilience of Malaysia’s tourism sector. Furthermore, the research identifies significant gaps in existing knowledge, particularly the need for localized studies that account for the unique geographical, environmental, and socio-cultural characteristics of Malaysian destinations. The findings suggest that comprehensive, context-specific policies are essential to address these dual challenges effectively and ensure the long-term sustainability and resilience of Malaysia’s tourism industry.
