The millipede genus Sphaerobelum Verhoeff, 1924, in Thailand, with descriptions of three new species (Diplopoda, Sphaerotheriida, Zephroniidae)
Authors: Srikampha Khanet , Wesener Thomas , Likhitrakarn Natdanai , Sutcharit Chirasak , Srisonchai Ruttapon
Published: February 2025

Three new species of the giant pill-millipede genus Sphaerobelum Verhoeff, 1924, from Thailand and Laos, are described based on an integrative approach that combines morphological characters and COI data; these are S. nonghinensis Srikampha & Srisonchai, sp. nov., S. onyx Srikampha & Srisonchai, sp. nov., and S. petramurum Srikampha & Srisonchai, sp. nov. Additionally, new material of previously described species, S. aesculus Rosenmejer & Wesener, 2021, S. truncatum Wongthamwanich, 2012, and S. turcosa Srisonchai & Pimvichai, 2023, were collected and examined. The new species can be distinguished from all congeners by a combination of unique characters, including body colour, endotergum, vulva, and details of the telopods. The validity of these new species is further supported by high genetic distances from their congeners in the 658 base pairs of the COI barcoding fragment, ranging from 13.24–30.12%. Preliminary phylogenetic analyses using Bayesian inference and maximum likelihood indicate that each new species forms a distinct clade, supporting their morphological uniqueness, though the interrelationships with most other congeners remain unsupported. All new species are restricted to narrow distribution areas in Thailand and Laos, suggesting they are endemic to these regions. Morphological characters of the new species are illustrated, and an identification key and a distribution map for known Sphaerobelum species in Thailand are also provided.
Faire le deuil de l’idéalisation et réparer les idéaux dans le climat humain
Authors: Thompson Caroline , Weintrobe Sally
Published: February 2025

Weintrobe soutient que la plupart des gens sont dans un retrait psychique collectif face à la gravité de la crise climatique. C’est la bulle climatique. La crise climatique fait référence à la crise dans le climat humain, qui détermine l’état des climats sociaux et physiques. Reconnaître et posséder son « exception intérieure », un coin ordinaire mais tenace de narcissisme, est une des clés pour sortir de la bulle climatique. Qu’il s’agisse du soi ou des groupes, l’exception idéalise le sentiment d’avoir le droit d’ignorer les limites et les frontières et elle sape les idéaux de soin. L’exception entrave le travail sur la culpabilité. Weintrobe explore différents types de culpabilité, les liant à différents types de sentiment « de se sentir le droit de » et de cupidité, les illustrant par des scènes de L’Enfer de Dante.
Comment les usages de la vidéo 360° facilitent l’apprentissage d’habiletés en Éducation Physique et en Sport
Authors: Rolland Cathy , Roche Lionel , Hagin Vincent , Cunningham Ian
Published: February 2025

L’analyse SWOT que nous avons réalisée porte sur les études scientifiques de ces dix dernières années dont l’objet d’étude concerne l’usage de vidéos 360°. Ces dernières constituent un nouvel outil technologique au service d’objectifs d’optimisation de la performance sportive. Elles rejoignent ainsi la vidéo 2D, le chronomètre ou le capteur de fréquence cardiaque traditionnellement utilisé dans l’entraînement. La plupart des études révèlent qu’elles peuvent constituer des outils bénéfiques d’accompagnement des processus d’apprentissage des habiletés et de soutien de la motivation. Cette potentialité dépend des circonstances particulières de leurs usages (niveau d’expertise des athlètes, conditions de visionnage notamment). La littérature révèle que l’usage de vidéos 360° ne peut se substituer aux processus adaptatifs générés par l’exécution effective des tâches à réaliser. De plus amples recherches permettront une compréhension plus fine de l’efficacité des usages de la vidéo 360°. Les faiblesses et les menaces dévoilées dans cette SWOT constituent des éléments à considérer pour améliorer l’usage de la vidéo 360° dans une perspective de soutien aux processus d’apprentissages en éducation physique et en sport.

Authors: Gaudin Cyrille , Isserte Simon , Chaliès Sébastien
Published: February 2025

Cet article vise à présenter et étudier un dispositif expérimental d’entraînement de football proposant des usages originaux et articulés de technologies numériques au service de l’apprentissage d’actions collectives. Élaborés conjointement par des chercheurs et des formateurs, ces usages sont conceptualisés à partir d’un cadre théorique singulier. Sur cette base, un protocole de recherche transformatif constitué de deux phases a été mis en œuvre auprès de trois entraîneurs de football engagés dans le Brevet d’Entraîneur de Football (BEF). La première, dite de formation, consistait à former ces trois entraîneurs à formaliser, enseigner, accompagner et évaluer des actions collectives à l’aide de technologies numériques. La seconde, dite d’intervention consistait à les engager dans la mise en œuvre de ce dispositif dans leur propre contexte d’entraînement. À partir d’entretiens d’autoconfrontation avec les entraîneurs et de remise en situation avec les joueurs, l’étude présentée ici vise à analyser leurs activités lors de cette phase d’intervention. Les résultats mettent en exergue que, dans certaines circonstances, les technologies numériques constituent de véritables technologies cognitives au sens où elles peuvent soutenir et enrichir les activités des entraîneurs, mais également des joueurs, face à la complexité de l’objet d’entraînement action collective .

Authors: Zhang Qi , Shi Qiang , Alatas Bilal , Yuan Yu-His
Published: February 2025

In response to the challenges posed by globalization and rapid technological advancements, traditional static pricing models are no longer sufficient to capture the dynamic nature of consumer behavior and market fluctuations. This study proposes a “Multi-dimensional Dynamic Pricing Optimization and Consumer Behavior Prediction Model Driven by Big Data,” which integrates multi-source data and reinforcement learning to improve dynamic pricing strategies. Through a hybrid model architecture using Random Forest and LSTM, it captures both static and time-series features. Experimental results show that the proposed model significantly outperforms baseline models, achieving a 43% reduction in Mean Squared Error (MSE), a 28% decrease in Mean Absolute Percentage Error (MAPE), a 6.5% increase in Accuracy, and a 14.7% increase in Cumulative Revenue. These findings confirm the model's ability to enhance prediction accuracy, optimize pricing strategies, and maximize revenue, demonstrating its potential for real-world applications in industries like e-commerce, finance, and advertising.
An evaluation of church planting models in contemporary Pentecostal missions enterprise in Ghana
Authors: Kenin Emmanuel A.
Published: February 2025

Background: Over the centuries, various generations have used various models to not only evangelise people but organise them in communities of believers (or churches) for effective discipleship of these Christian converts as commanded by Jesus Christ. The various church planting models employed by mission organisations and churches have served different purposes at different times. A major hindrance to the church planting enterprise of missional churches is inadequate human resources. This is especially profound in the rural and peri-urban areas where the scourge of the impact of rural-urban migration is felt most. This phenomenon tends to put a limitation on the availability of human capital for the successful manning of newly planted churches. In most of these places, the common mantra among church planters and missionaries is ‘we lack leaders here so we are unable to plant more churches’.Objectives: This research evaluates the various church planting models in the Church of Pentecost and proposes an indigenous model for planting Indigenous local churches and raising indigenous leaders for the same.Method: This research employs participant observation, review of church reports as well as personal conversations with mission practitioners in the rural and peri-urban areas of Ghana.Results: The Jesus Mission Model (JMM) proposed by this research seeks to proffer a contextual solution for challenges confronting church planting efforts in rural and peri-urban areas of Ghana.Conclusion: The model proposed in this research addresses the challenge of raising indigenous leaders for sustainable indigenous churches in Ghana’s rural and peri-urban areas.Contribution: The study proposes a contextualised church planting model, the JMM for rural and peri-urban areas in Ghana.

Authors: Hoang Tung T. , Lo-Cao Edward , Girgis Shenouda , Lim Ridia
Published: February 2025

Background: Early post-operative intraocular pressure (IOP) control following Baerveldt tube (BVT) implant is critical, especially in cases with advanced glaucoma.Aim: This study aimed to review the efficacy and safety of a releasable wick suture for early control of post-operative IOP in patients implanted with a 350 mm2 BVT.Setting: This study is a retrospective chart review of all patients implanted with BVT and a releasable 9–0 Vicryl wick placement, performed under one surgeon.Methods: Efficacy data of IOP and number of glaucoma medications were collected pre-operatively and on post-operative day 1 and weeks 1, 4, 6, 8 and 12. Safety, visual acuity and wick removal data were also collected.Results: The utilisation of a releasable wick suture with BVT implantation gives early post-operative IOP control and fewer medications day 1 post-operatively. The IOP and number of medications significantly decreased at each time point while the visual acuity did not significantly change compared to the pre-operative level after 12 weeks in the total population. Mean IOP of patients with wick removal increased in hypotony cases and decreased in high pressure cases. There was no difference in terms of safety profile between cases with wick remaining and wick removal.Conclusion: The use of a releasable wick suture with BVT implantation gives early IOP control with fewer glaucoma medications in the first three post-operative months and the option of suture removal when IOP is too high or low.Contribution: The study introduced a novel method for early IOP control after BVT implant.
Hypercoagulation after neoadjuvant immunochemotherapy as a new prognostic indicator in patients with locally advanced gastric cancer undergoing surgery
Authors: Li Tian-Hao , Sun Xiong , Li Cheng-Guo , Yin Yu-Ping , Tao Kai-Xiong
Published: February 2025

BACKGROUND

Coagulation status is closely related to the progression of malignant tumors. In the era of neoadjuvant immunochemotherapy (NICT), the prognostic utility of coagulation indicators in patients with locally advanced gastric cancer (LAGC) undergoing new treatments remains to be determined.

AIM

To determine whether hypercoagulation is an effective prognostic indicator in patients with LAGC who underwent radical resection after NICT.

METHODS

A retrospective analysis of clinical data from 104 patients with LAGC, who underwent radical resection after NICT between 2020 and 2023, was performed. D-dimer and fibrinogen concentrations were measured one week before NICT, and again one week before surgery, to analyze the association between these two indicators and their combined indices [non-hypercoagulation (D-dimer and fibrinogen concentrations within the upper limit of normal) vs hypercoagulation (D-dimer or fibrinogen concentrations above the upper limit of normal)] with prognosis. After radical resection, patients were followed-up periodically. The median follow-up duration was 21 months.

RESULTS

Data collected after NICT revealed that the three-year overall survival (OS) and disease-free survival (DFS) rates the non-hypercoagulation group were significantly better than those in the hypercoagulation group [94.4% vs 78.0% (P = 0.019) and 87.0% vs 68.0% (P = 0.027), respectively]. Multivariate analysis indicated that hypercoagulation after NICT was an independent factor for poor postoperative OS [hazard ratio (HR) 4.436, P = 0.023] and DFS (HR 2.551, P = 0.039). Pre-NICT data demonstrated no statistically significant difference in three-year OS between the non-hypercoagulation and hypercoagulation groups (88.3% vs 84.1%, respectively; P = 0.443).

CONCLUSION

Hypercoagulation after NICT is an effective prognostic indicator in patients with LAGC undergoing radical gastrectomy.

Authors: Mao Yucheng , Liu Fulan
Published: February 2025

The advent of artificial intelligence has led to the emergence of a novel form of machine translation (MT), namely neural machine translation (NMT), which has significant potential for application in the field of second language (L2) writing. This review aims to synthesize the various approaches to effectively integrating NMT into L2 writing pedagogy and practice. A comprehensive search was conducted in a well-established database based on specific criteria. The findings indicate that NMT is an effective tool for developing L2 writing skills and that it is particularly well-suited to advanced L2 writers, as higher proficiency levels result in more critical reflection on NMT output. Finally, this review demonstrates that NMT has significant pedagogical implications. It serves as an invaluable online reference tool for L2 writing, provided that teachers introduce students to its benefits and limitations by implementing various teaching approaches.

Теоретико-методичні основи визначення договірних показників процесу обробки суден
Authors: Kirillova E. , Pavlova N. , Magamadov A. , Muradian A. , Kirillova V.
Published: February 2025

Вперше у транспортній науковій літературі запропоновано узагальнений підхід до створення механізму узгодження умов щодо прийняття договірних показників процесу обробки суден у формі алгоритму досягнення компромісу, консенсусу та довготривалої згоди між учасниками договірного процесу. Установлено, що операції цього алгоритму належить виковувати за схемою: дискусія (початок, «середина», закінчення) – діалог І – досягнення компромісу – діалог ІІ – досягнення консенсусу – діалог ІІІ – досягнення довготривалої згоди. Визначена змістовна структура алгоритму з характеристикою обов’язкових операцій його кроків (етапів). Показано, що механізм узгодження управління слід ґрунтувати на поєднанні потенціалу координації й взаємодії, що забезпечує гармонізацію відносин між сторонами договору. Наведено сучасну трактовку указаних понять у термінах ділового спілкування суб’єктів підприємницької діяльності. Доведено, що взаємодію як складову управління потрібно визначати в якості не тільки сприяння (співробітництва) але й протидії (конкуренції). Установлено режими реалізації алгоритму – за усіма кроками (для довготривалої згоди) й за кроками від початку дискусії до досягнення компромісу (для оперативної перспективи). Показано, що прояв «людського» фактору при діловому спілкуванні учасників договірного процесу у формі суб’єктивізму й «ринкового егоїзму» переборюється шляхом створення для етапів діалогів І-ІІІ й досягнення компромісу, консенсусу та довготривалої згоди адекватного й суворого у формальному сенсі методичного інструментарію. Розроблено методичне забезпечення розв’язання завдань щодо встанов- лення договірних рівнів показників: ставки диспачу, норми завантаження/ розван- таження суден і акордної ставки на перевалювання вантажу в ймовірнісній постановці. Визначено, що наступний етап досліджень належить зв’язувати з розвитком алгоритму узгодження договірних умов і розробкою комп’ютерних технологій реалізації методів встановлення згаданих показників ПОС.

Показано, що в малих безпілотних морських суднах найчастіше використовують електромеханічні системи різного типу. Ці системи забезпечують керування рулем судна, його рушійними пристроями, використовуються для інших допоміжних механізмів судна. З аналізу джерел встановлено, що електро-механічні системи ефективні в системах стабілізації руху суден, наприклад, у системах автопілоту. При технічній реалізації автопілотів і електрорушіїв використовують різного типу контролери і до цього часу відсутні апробовані рішення щодо алгоритмів керування ними. Показані основні принципи створення ефективних математичних моделей електромеханічних систем, побудованих на основі електричних двигунів. Ця побудова проходить за допомогою спрощення математичного опису двигунів і використання при моделюванні структурних схем. Наведено можливості використання та обрання асинхронних трифазних електродвигунів, призначених для застосування у різних механізмах і системах електроприводу морських суден і, зокрема, у електрорушіях невеликих безпілотних плавальних апаратів. Пропонується регулювання швидкості для таких двигунів здійснювати за допомогою керованого силового перетворювача при постійній частоті джерела живлення. Наведена послідовність побудови моделі електромеханічної системи, яка регулює швидкість асинхронного двигуна. Модель враховує нелінійні залежності двигуна (формула Клоса), «вентиляторне» навантаження та нелінійні елементи типу «обмеження» системи регулювання. Запропоновано використання у такій системи спрощеного нечіткого контролера, який відрізняється симетричною побудовою процедур фазіфікації. Наведені результати моделювання електрорушійної системи малого безпілотного судна при використанні нечіткого контролера. Запропоноване рішення дозволяє ефективно проводити подальший синтез контролерів керування автопілотів, рушіїв тощо, дозволяє попередньо визначати енергетичні втрати процесів регулювання.

QR Code Integration in Retail Pharmacy: A Service Quality Framework Analysis using PLS-SEM on Customer Outcomes
Authors:   University of Santo Tomas Graduate School, Tulinao Catrina Mae S. , Bool Nelson C. ,   University of Santo Tomas Graduate School, Garcia Dante R. ,   University of Santo Tomas Graduate School
Published: February 2025

This study critically examines the influence of QR code integration within the retail pharmacy context on key performance metrics, including service quality, store attributes, waiting time, customer satisfaction, trust, and repurchase intention. Employing partial least squares structural equation modeling (PLS-SEM), this research analyzed data from customers to elucidate the underlying interdependencies of variable and service delivery outcomes. Instrumental to the analysis is the assurance of minimal collinearity, as evidenced by the Inner VIF values consistently falling below the threshold of 3, thereby confirming the reliability of the estimated model. Empirical findings indicate that QR code deployment exerts a statistically significant positive effect on service quality (β = 0.43, p < 0.001), store attributes (β = 0.45, p < 0.01), and waiting time (β = 0.38, p < 0.001), collectively accounting for 52% of the variance in customer satisfaction (R² = 0.520). Moreover, customer satisfaction emerged as a pivotal mediator, robustly influencing trust and repurchase intention, with indirect pathways and direct effects substantiating its role in shaping customer loyalty. Although the variance explained by trust is modest (R² = 0.123), the cascading effect on repurchase intention (R² = 0.332) underscores the systemic importance of a holistic digital integration strategy. This study contributes to the extant literature by delineating the multifaceted impact of digital tools in healthcare service environments and underscores the necessity for comprehensive infrastructural support to fully harness the potential of QR code technology.

Authors: Costa de Almeida Felipe , Ferreira Lima José Júlio , Cassiano Lima Alberto Patrick
Published: February 2025

Tomé-Açu, localizado no nordeste do estado do Pará, tem se destacado pelo emprego de Sistemas Agroflorestais (SAFs) na produção agrícola do município. Para além da perspectiva ambiental e econômica, este trabalho apresenta uma análise da estruturação socioespacial de Tomé-Açu, a fim de explicar como os SAFs estão inseridos na forma de assentamentos urbanos e periurbanos do município. Dois pontos são levados em consideração para a elaboração da pesquisa: o primeiro é a expansão do tecido urbano em Tomé-Açu e a formação de um território fragmentado; e o segundo é a dispersão dos SAFs no território municipal. Sabe-se que os SAFs foram tão reproduzidos pelo município a ponto de estarem presentes em diferentes ocupações espaciais. As conclusões indicam que a expansão de agroflorestas em Tomé-Açu estabelece um sistema espacial de transição entre fragmentos florestais e áreas de usos do solo distintos. Além disso, dentre as categorias morfológicas estudadas, conclui-se que os SAFs podem ser elementos estruturantes da organização espacial de núcleos urbanos e protonúcleos ao estarem presentes nas franjas urbanas e, principalmente, de aglomerados rurais, onde os SAFS aparecem articulados aos demais espaços e as atividades rurais são mais expressivas.

We present the case of a 42-year-old male patient with a history of bilateral lung transplantation and chronic graft dysfunction. The patient presented to the adult emergency department due to acute heart failure. During his stay in the emergency room and in outpatient follow-up, cardiac multi-imaging led to the diagnosis of double-chambered right ventricle with associated hypertrophic cardiomyopathy. Given the presence of advanced lung disease and poor adherence to immunosuppressant medication as well as clinical follow-ups, the patient was deemed unsuitable for re-lung transplantation. The optimization of his immunosuppressive medication was prioritized, and beta-blockers were added as part of the treatment for dynamic right ventricular  outflow obstruction. He was referred to pulmonary rehabilitation, currently showing a partially favorable  evolution to functional class II.

Radon gas, a naturally occurring radioactive element, presents significant health risks, particularly in areas with fractured basement geology, where subsurface characteristics can elevate its concentration. As the second leading cause of lung cancer globally, after smoking, radon exposure is a critical public health concern. This study seeks to evaluate the concentration levels of radon gas, analyze its potential health risks to the residents, and provide insights into the environmental factors influencing radon accumulation in this area. Thirty (30) samples were collected for groundwater from various locations within the study area. Groundwater samples were collected from selected drinking water sources using 1.5 litre plastic bottles. Radon gas concentration was measured using a RAD7 electronic radon detector for soil and RAD7 H2O for groundwater. The data obtained was analysed using a statistical tool to perform a one-way Analysis of Variance (ANOVA). The samples were also subjected to decay corrections to ensure the accuracy of the results. The data were analysed using descriptive and inferential statistics, with statistical significance set at p<0.05. Groundwater radon concentrations ranged from 0.576Bq/L to 6.54Bq/L with a mean concentration value of 2.81 Bq/L and a standard deviation of 1.73 Bq/L. The mean annual effective dose for radon due to inhalation, ingestion and whole- body are 0.0254 mSvy^(-1), 0.00987 mSvy^(-1) and 0.0352 mSvy^(-1) respectively. The results were all below the recommended threshold of 0.1 mSvy^(-1) set by the World Health Organization (WHO). The Excess Lifetime Cancer Risk (ELCR) value of 12.34 × 10^(-5) was obtained which corresponds to about 1.23 in 10,000 risk of developing cancer over a lifetime due to radon exposure through water. The study on radon concentration in groundwater from the Ayetoro Housing Scheme, Oyo, found an average radon level of 2.82 Bq/L, below the EPA's maximum contaminant level (MCL) of 11.1 Bq/L. This indicates that residents in the area are not at significant risk from radon exposure at the time of the study. However, it was observed that inhalation of radon from water presents a higher radiological hazard than ingestion. The study recommends regular radon monitoring in the area to ensure continued safety
Research on the Differences between Expectations and Reality in Primary School Classroom Teaching - From the Perspective of Teacher Education Internship Experience
Authors:   School of Education Science, Shaoguan University, HUANG Xiaoru , YANG Lian ,   School of Education Science, Shaoguan University
Published: February 2025

Against the backdrop of current education reform, primary school classroom teaching is undergoing unprecedented changes. However, have these changes truly met the expectations of teacher trainees? The study attempts to explore this issue in depth from the perspective of the graduation internship experience of normal university students. By interviewing ten normal university students (grade 4) , we aim to understand their educational internship experiences, with a focus on the gap between expectations and actual teaching in primary school classrooms, and analyze the underlying reasons for this gap. Research has found that normal school students generally expect diversified and innovative teaching methods, hoping that education can respect and meet the personalized needs of each student, and they expect the classroom to have more interactive features or greater interactivity. However, in actual teaching, traditional teaching methods still dominate primary school classrooms, and personalized education is difficult to effectively implement. Most classrooms have problems such as low student participation and limited teacher-student interaction. This difference is due to various reasons such as traditional teaching concepts, teachers􀆳 professional qualities, and school resource limitations. Therefore, schools, teachers, and students should work together to improve teaching methods, promote personalized education, and strive to enhance classroom interactivity.
No-maternidades en deconstrucción. Experiencias disruptivas de género y parentesco
Authors:   , Bogino Larrambebere Mercedes
Published: February 2025

This research explores the experience of non-motherhoods in contemporary sociocultural contexts. The study proposes a feminist ethnography, understood as a focus, method and text, used to understand the perspective of the female subjects. It analyses biographical stories from women who are not mothers, due to various reasons and sociostructural conditions. The research confirms the influence of gender and kinship norms over constructing the desire for motherhood and the duty to procreate, and on (non)reproductive decisions. Five key ideas stand out among the contributions from this thesis: 1) the social price of non-motherhood is lack of prestige; 2) non-motherhood as a “hidden desire” and the search for “a place of one’s own”; 3) the hegemony of motherhood is altered and re-thought by disruptive social practices that question it; 4) the role of social mothers, who perform chosen or delegated mothering practices; and 5) building new reference points in gender and kinship relations, and in different living spaces. The thesis concludes that autonomy practices recounted by the informants become resistance or transgression practices, shaping disruptive experiences of gender and kinship.
Utilization and Application of Essential Oils for Managing Stored Grain Insect Pests
Authors: Dr. Seema Kodesia
Published: February 2025

Essential oils are natural phytochemicals produced as secondary metabolites in aromatic plants. These complex mixtures of volatile compounds typically consist of 20 to 60 different molecules in varying concentrations. Due to their lipophilic nature and lower density compared to water, essential oils can interfere with key metabolic, biochemical, physiological, and behavioral processes in insects. Many essential oils and their components have demonstrated repellant, antifeedant, ovicidal, oviposition-inhibitory, and developmental-inhibitory effects on insects. These effects are believed to result from disruptions to the respiratory and nervous systems of the insects.
As a source of bioactive molecules, essential oils offer an eco-friendly alternative to traditional insect control agents. They are largely selective in their action and have minimal or no adverse effects on the environment or non-target organisms, including humans. Consequently, essential oil-based formulations hold promise as sustainable methods for insect management, particularly in the context of protecting stored grains.

The reproductive processes of fish and their early developmental stages are profoundly influenced by climate change, particularly through temperature variations and ocean acidification. Seasonal temperature shifts are essential for initiating spawning activities, with cooler temperatures stimulating reproduction in autumn-spawning species and warmer temperatures triggering spring spawners. However, rising global temperatures have been shown to disrupt these cycles, leading to shortened spring spawning periods and delayed autumn spawning. The extent and duration of temperature increases can cause significant reproductive challenges, from altered spawning schedules to complete reproductive failure, especially in species with narrow geographic distributions.
Furthermore, temperature changes affect the endocrine system by reducing ovarian estrogen production, directly inhibiting reproductive success. Early life stages, such as eggs and larvae, are especially vulnerable to environmental changes, experiencing reduced survival rates, altered development, and disrupted growth patterns. Ocean acidification compounds these effects by impairing larval sensory functions and behavior, disrupting ecological interactions and hindering population replenishment. These combined effects highlight the critical need for understanding and mitigating the impacts of climate change on aquatic ecosystems to preserve biodiversity and maintain ecological balance.

The second wave of COVID-19 in India, was new, potentially more virulent
strain of SARS-CoV-2, identified as B.1.617.2, not only led to widespread
infection but also contributed to the sudden rise of COVID-19-associated
mucormycosis (CAM). This condition, commonly referred to as "Black
Fungus" due to the rapid necrosis and eschar formation, became a
significant concern. The most prevalent form of CAM is Rhino-Orbito-
Cerebral Mucormycosis (ROCM), which typically progresses from the nose
and sinuses to the orbit and, ultimately, to the brain. Maharashtra was the
most affected state, followed by Gujarat, with a noticeable correlation
between the seasonality of mucormycosis cases and the high incidence
observed in these regions during the study period. This review aims to
present the patterns of mucormycosis cases across India from May to July
2021, along with demographic characteristics, such as age and gender, of
the affected population.

Abstract. Carbonate U–Pb dating has become a key tool for Quaternary palaeoclimatology and palaeoanthropology beyond the ∼800 ka age limit of Th–U disequilibrium dating. U–Pb geochronology is based on the paired radioactive decay of 238U to 206Pb and of 235U to 207Pb. Current carbonate U–Pb data processing algorithms rely mostly on the 206Pb/238U clock and attach little weight to the 207Pb/235U data. A key weakness of this approach is the need to correct the 206Pb/238U data for initial 234U/238U disequilibrium, which may cause an excess (or deficit) in radiogenic 206Pb compared to secular equilibrium. We introduce a new disequilibrium correction algorithm, using matrix exponentials. This algorithm can be used to undo the effects of U-series disequilibrium using either an assumed initial composition, or a measured set of modern 234U/238U (and optionally 230Th/238U) activity ratios. Using a deterministic Bayesian inversion algorithm, we show that disequilibrium corrections work well for relatively young samples but become unreliable beyond 1.5 Ma and impossible beyond 2 Ma. Using theoretical models and real world examples from Siberia, South Africa and Israel, we show that the uncertainty of the disequilibrium correction of such old samples exceeds the correction itself. Previous ‘Monte Carlo’ error propagation methods underestimate these uncertainties by up to an order of magnitude. We advocate the use of the 207Pb/235U isochron method as a more accurate and precise alternative to 206Pb/238U geochronology for >2 Ma carbonates that are suspected to have experienced significant levels of initial 234U/238U disequilibrium.

Abstract. The new mineral, heimaeyite, was found among the fumarolic encrustations collected on Eldfell volcano, on the island of Heimaey, Iceland. The mineral formed as microscopic rounded aggregates (<50 µm) and rounded grains (<10 µm) mixed with tiny needles of koryakite and a mineral phase with an NaMgAl(SO4)3 composition. It was formed in scoria consisting of anhydrite, hematite, and cristobalite. Other associated minerals are tamarugite, hexahydrite, löweite, and langbeinite. Heimaeyite is orange with a yellowish streak. It is translucent with a vitreous lustre. The calculated density is 2.783 g cm−3. The chemical analysis gives a composition of Na2.93Al0.82Fe0.25S2.99O12.05. The ideal formula is Na3Al(SO4)3 with 10 % to 25 % replacement of Al with Fe. Single-crystal X-ray diffraction analysis shows that it is trigonal and has a space group of R3‾ with unit cell parameters of a=13.4326(9) Å, c=8.9818(7) Å, V=1403.5(2) Å3, and Z=6. The X-ray powder diffraction resembles that of Na3V(SO4)3 (PDF 39-0243), with which it is isostructural. They both belong to the K7Nb(SO4)6 structure type. In the crystal structure, the octahedral coordinations of the cation (in heimaeyite this is Al) are connected by sulfate tetrahedra in a “pin-wheel” arrangement into chains extending along [001]. The chains are interconnected by [NaO6] distorted trigonal prism coordinations. Fe substitutes for Al in the larger of the two symmetry-independent octahedral sites. Synthetic pure Na3Al(SO4)3 was prepared through a solid-state reaction at 550 °C, and its structure was refined by the Rietveld method. It shows a smaller difference in size between the two octahedral sites than the natural sample.
Exploring Students’ Perspective on Online Teaching-Learning Process: Opportunities and New Challenges
Authors: Batool Muazma , Khurshid Khalid
Published: February 2025

This study aimed to analyze students’ perspectives on the nature, opportunities, and new challenges of the online teaching-learning process at the higher education level. A quantitative approach was used to collect survey data from 751 students (358 males and 393 females) across five public sector universities in South Punjab, Pakistan. The study employed a Likert-type scale questionnaire designed by the researcher. Data were analyzed using SPSS. The findings revealed no statistically significant differences based on gender, faculty, or program concerning perceptions of online learning. While students agreed on the opportunities provided by online learning, the challenges varied among different universities. Key opportunities included digital literacy enhancement, flexible learning, and exposure to global learning platforms. Challenges included lack of interaction, network connectivity issues, and technical difficulties. Higher education institutions (HEIs) should provide workshops on digital literacy and guidance services to support students in overcoming online learning challenges. An asynchronous learning mode is recommended for flexibility.

Aging is a predominant risk factor for several diseases associated with reduced life expectancy. To address this risk factor, several studies have proposed the combined use of porang glucomannan and a high-protein diet to improve various aging markers. The aim of this study was to determine the effects of porang glucomannan and high-protein combination diet as an anti-aging agent. An experimental study using a post-test-only control group design was conducted using Sprague Dawley white rats. The animals were randomly divided into four groups with different treatments as follows: normal control, D-galactose, high-protein diet, and a combination of porang glucomannan and high-protein combination diet. Blood samples were then collected from the ophthalmic vein on day 58 for biomarker measurement using the enzyme-linked immunosorbent assay (ELISA) method. The parameters measured were superoxide dismutase (SOD), malondialdehyde (MDA), interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), insulin growth factor-1 (IGF-1), NOD-like receptor family pyrin domain-containing protein 3 (NLRP3), growth differentiation factor-11 (GDF11), and α-Klotho levels. The results showed that the combination of porang glucomannan and high-protein diet could improve oxidative stress, inflammation, and aging markers. The analysis of variance (ANOVA) test followed by post-hoc least significant difference (LSD) showed significant differences between the combination diet and high protein group (p<0.0001). In addition, the average levels of oxidative stress markers (SOD and MDA) in porang glucomannan and high-protein combination group were improved significantly. Similar results were also obtained for inflammatory markers (IL-6 and TNF-α) and aging markers (NLRP3, IGF-1, GDF-11, and α-Klotho). The mean NRLP-3 levels in glucomannan and high-protein combination group were not significantly different compared to control. The study highlights that the combination of porang glucomannan and a high-protein diet effectively improved various aging markers.
