Published: January 2025

Hybrid teaching, which integrates traditional in-person learning based on students’ perspectives where online learning offers a flexible approach to education, combines the benefits of technology with face-to-face interactions. Moreover, teaching and learning in a hybrid way met several challenges for both teachers and learners, including technological problems, time management, communication difficulties, and assessment complexities. This systematic review investigates six main research questions: (1) What pedagogical frameworks are used in hybrid teaching and learning? (2) How can we enhance students’ engagement in hybrid teaching and learning? (3) What is the impact of technological integration on hybrid learning scenarios, both for students and teachers? (4) How do training and support measures influence the willingness and ability of university teachers to implement hybrid teaching formats? (5) How do formative assessment and feedback methods in hybrid learning environments enable teachers to effectively monitor student progress and provide tailored support? (6) How does the implementation of hybrid learning affect student learning outcomes? This study identifies the following key themes: technological integration, pedagogical innovation, faculty support, student engagement, assessment practices, and learning outcomes. Our contribution of this literature review is related to teaching and learning by showing teachers the most appropriate way to avoid the challenges encountered when teaching in a hybrid way. These include strong technology integration, innovative pedagogical strategies, strong academic development and support, active student engagement, effective assessment practices, and positive learning outcomes.

Authors: Quisbert-Trujillo Ernesto , Ben Rejeb Helmi
Published: January 2025

Digitalization is reshaping the landscape of sustainability in enterprises by enhancing information flows within socio-technical systems and enabling more informed decision-making through advanced communication and data capabilities. However, while digitalization creates opportunities to adopt environmental practices and deploying sustainable strategies, it also introduces complexities and challenges. This study examines the information-centered drivers of digitalization that push enterprises toward sustainable practices, such as technological advancements and the increased demand for transparency, while identifying challenges, including integration costs, technological readiness, and managerial hesitation. Using a multidimensional framework that combines capabilities, environmental practices, and motivations, we provide insights into how technology can both support and challenge sustainability efforts in industry. Our aim is to introduce a methodology to guide the development of strategies for facilitating environmental transitions of enterprises. Within the context of informational capabilities, this scoping review identifies two environmental archetypes—spontaneity and planning—that represent common workforce mindsets toward sustainability. It also classifies universal practices and motivations, with associations being validated through a focus group of members from a French industrial consortium, which also facilitates understanding how digitalized capabilities impact environmental actions and behavioral dynamics. The key findings reveal that while digital communication capabilities significantly enhance the return on investment for environmental practices, barriers remain, such as insufficient alignment of digital tools with sustainable outcomes and variable technology access across industries. The results also underscore the role of product-data and sensor-based analytics in reducing environmental impacts, inviting a further exploration of digitalization’s role in sustainability within the frameworks of behavioral and organizational theories.
Effect of Freeze–Thaw Cycles on the Microstructure Characteristics of Unsaturated Expansive Soil
Authors: Li Xinyu , Cong Shengyi , Tang Liang , Ling Xianzhang
Published: January 2025

The term “engineering cancer” refers to expansive soil, whose properties threaten the stability and safety of structures. As a result, appropriate steps must be taken to guarantee the sustainable development of buildings. To explore the impact of freeze–thaw cycles (FTCs) on the microscopic characteristics of unsaturated expansive soil in the cold region, the mineralogical composition and microstructure were analyzed using X-ray diffraction (XRD), thermogravimetric analysis, and scanning electron microscopy (SEM). The influence of repeated FTCs on the characteristics of particle morphology and pore structure in expansive soil was quantitatively examined. The findings indicate that, in comparison to other expansive soil samples, the Yanji expansive soil is particularly susceptible to failures due to its high sand content and low liquid limit. The FTCs significantly alter the microstructure, leading to increased complexity in the particle edge shapes, a transition in particle distribution from dispersed to more concentrated, a reduction in larger particles, and a more intricate spatial arrangement of particles. As moisture content rises, the impact of FTCs becomes increasingly pronounced. The particle distribution’s area probability index and fractal dimension are identified as medium-variability parameters, with a high-variation coefficient before the 3rd FTC, which then gradually decreases. The repeated FTCs result in particle breakage and agglomeration, causing the particle size to become more uniform and the soil’s microstructure to stabilize after 3–5 FTCs. These findings contribute to understanding the FTC behavior of expansive soils, provide theoretical support and scientific guidance for disaster prevention and control measures, as well as for the sustainable development of engineering projects involving expansive soil sites.

High-Performance Carrier Phase Recovery for Local Local Oscillator Continuous-Variable Quantum Key Distribution
Authors: Ma Jiayu , Zhou Chao , Qi Dengke , Chen Ziyang , Sun Yongmei , Yu Song , Wang Xiangyu
Published: January 2025

Continuous-variable quantum key distribution (CV-QKD) has been increasingly studied, which offers the advantage of compatibility with modern coherent optical communication systems. In contrast to CV-QKD with a transmitting local oscillator, the local local oscillator CV-QKD avoids the security vulnerabilities of a local oscillator by generating a local oscillator at the receiver. In practice, the frequency offset of the two lasers introduces extra phase noise, which is generally suppressed by various carrier phase recovery algorithms. However, the accuracy of carrier phase recovery can be influenced by the power of the pilot tone, particularly as the transmission distance increases. To further improve accuracy, we propose a method based on the unscented particle filter algorithm, to increase the accuracy of phase estimation, effectively restore the quantum signal and reduce excess noise. In our work, we demonstrated a local local oscillator CV-QKD experiment with a finite-size block of 1×108 under a transmission distance of 50 km. Through our method, we achieved a secret key rate of 525 kbps, which represents a 28% improvement. These results confirm that our proposed method not only improves the accuracy of carrier phase recovery, but also provides a new approach for future research on algorithms for long-distance CV-QKD. Furthermore, our study improves the phase compensation performance, enabling the orthogonal components of the quantum signal to exhibit enhanced symmetry in phase space.
Maximizing Information Dissemination in Social Network via a Fast Local Search
Authors: Tian Lijia , Ji Xingjian , Zhou Yupeng
Published: January 2025

In recent years, social networks have become increasingly popular as platforms for personal expression, commercial transactions, and government management. The way information propagates on these networks influences the quality and expenses of social network activities, garnering substantial interest. This study addresses the enhancement of information spread in large-scale social networks constrained by resources, by framing the issue as a unique weighted k-vertex cover problem. To tackle this complex NP-hard optimization problem, a rapid local search algorithm named FastIM is introduced. A fast constructive heuristic is initially used to quickly find a starting solution, while a sampling selection method is incorporated to minimize complexity during the local search. When the algorithm stalls in local optima, a random walk operator reorients the search towards unexplored regions. Comparative tests highlight the proposed method’s robustness, scalability, and efficacy in maximizing information distribution across social networks. Moreover, strategy validation trials confirm that each element of the framework enhances its overall performance.

Published: January 2025

Marine life exploration is constrained by factors such as limited scuba diving time, depth restrictions for divers, costly expeditions, safety risks to divers’ health, and minimizing harm to marine ecosystems, where traditional diving often risks disturbing marine life. This paper introduces Nu (named after an ancient Egyptian deity), a 3D-printed Remotely Operated Underwater Vehicle (ROUV) designed in an attempt to address these challenges. Nu employs Long Range (LoRa), a low-power and long-range communication technology, enabling wireless operation via a manual controller. The vehicle features an onboard live-feed camera with a separate communication system that transmits video to an external real-time machine learning (ML) pipeline for fish species classification, reducing human error by taxonomists. It uses Brushless Direct Current (BLDC) motors for long-distance movement and water pump motors for precise navigation, minimizing disturbance, and reducing damage to surrounding species. Nu’s functionality was evaluated in a controlled 2.5-m-deep body of water, focusing on connectivity, maneuverability, and fish identification accuracy. The fish detection algorithm achieved an average precision of 60% in identifying fish presence, while the classification model achieved 97% precision in assigning species labels, with unknown species flagged correctly. The testing of Nu in a controlled environment has met the system design expectations.

Authors: Landeta-Bejarano Nathalie , Ruiz-Sinoga José , Orden-Mejía Miguel , Díaz-Chong Enrique
Published: January 2025

This study addresses the persistence of patriarchal structures and the reproduction of traditional gender roles in rural settings. In particular, this research explores agritourism, an emerging sector of rural tourism that, while providing economic opportunities in rural areas, also ends up perpetuating female subordination. In response to this issue, the manifestation of symbolic gender-based violence in the field of agritourism was analyzed, and a reliable and validated psychometric measurement scale was developed. The instrument identified and quantified the specific dimensions of symbolic gender-based violence in this context. To meet these objectives, the Delphi Method was used asynchronously for the design of the questionnaire, and an exploratory factor analysis was applied with a sample of 299 participants to validate its internal structure. The results indicate the existence of a robust structure made up of six key factors: feminized entrepreneurship, occupational self-segregation, stereotyped roles, limited access to land, glass ceiling, and wage discrimination. These findings contribute to a deeper understanding of the symbolic mechanisms of gender-based violence in agritourism and offer an analytical tool for future research in the field of gender studies and rural tourism.

Authors: Black Kristian , Ølgaard Sofie , Khoei Amelia A. , Glazer Clara , Ohl Dana A. , Jensen Christian Fuglesang S.
Published: January 2025

Infertility is a significant global health issue, affecting 8–12% of couples of reproductive age, with male factor infertility contributing to 30–50% of cases. Despite advances in assisted reproductive technologies, particularly intra-cytoplasmic sperm injection, male infertility remains understudied compared to female infertility. This review aims to explore the genetic underpinnings of male factor infertility, including identified genetic mutations, chromosomal abnormalities, and epigenetic factors, and to investigate the broader health implications for affected men. The emerging data suggest that male infertility is not only a reproductive issue but also a potential predictor of chronic diseases, including autoimmune disorders, cancer, and premature death. Additionally, the inheritance of male factor infertility and its potential effects on offspring health remains indeterminate. Studies have shown conflicting results regarding the impact of parental infertility and fertility treatments on the semen quality and reproductive health of offspring. This review summarizes the current understanding of the genetic causes of male infertility, highlights the impact of chromosomal disorders, reviews the spectrum of sperm quality and hormonal profiles, and discourses on the need for further research to clarify the relationships between parental subfertility, male infertility, and offspring health. By investigating these complex interrelationships, future research can help shape more effective diagnostic and treatment strategies for male infertility and its broader implications for men’s health and future generations.
Transcytosis of T4 Bacteriophage Through Intestinal Cells Enhances Its Immune Activation
Authors: Carroll-Portillo Amanda , Barnes October , Coffman Cristina N. , Braun Cody A. , Singh Sudha B. , Lin Henry C.
Published: January 2025

Interactions between bacteriophages with mammalian immune cells are of great interest and most phages possess at least one molecular pattern (nucleic acid, sugar residue, or protein structure) that is recognizable to the immune system through pathogen associated molecular pattern (PAMP) receptors (i.e., TLRs). Given that phages reside in the same body niches as bacteria, they share the propensity to stimulate or quench immune responses depending on the nature of their interactions with host immune cells. While most in vitro research focuses on the outcomes of direct application of phages to immune cells of interest, the potential impact of their transcytosis through the intestinal barrier has yet to be considered. As transcytosis through intestinal cells is a necessary step in healthy systems for access by phage to the underlying immune cell populations, it is imperative to understand how this step may play a role in immune activation. We compared the activation of macrophages (as measured by TNFα secretion) following direct phage application to those stimulated by incubation with phage transcytosed through a polarized Caco2 epithelial barrier model. Our results demonstrate that phages capable of activating TNFα secretion upon direct contact maintain the stimulatory capability following transcytosis. Furthermore, activation of macrophages by a transcytosed phage is enhanced as compared to that occurring with an equivalent multiplicity of directly applied phage.
Phosphorus Retention in Treatment Wetlands? A Field Experiment Approach: Part 1, Hydrology
Authors: Moustafa Mohamed Z. , Lal Wasantha A. M.
Published: January 2025

Stormwater Treatment Areas (STAs) are large wetlands constructed to reduce phosphorus (P) from agricultural and urban runoff into the Everglades Protection area. Wetland vegetation in these STAs reduce P in surface water, affects flow resistance, and causes delays of water deliveries. Vegetation resistance is commonly determined by the flow regime and vegetation porosity. Field experiments were conducted to seek alternative ways to estimate vegetation resistance in STAs. We generated small sinusoidal discharge perturbations superimposed on near-steady state flow conditions and measured in situ water levels inside the wetland. The elapsed time for the generated waves to reach various locations and wave amplitude attenuations inside the wetland were used to calculate porosity/transmissivity (K), a single parameter representing vegetation resistance. The vegetation index combined with calculated K distribution indicated that transmissivity is a straightforward way to represent vegetation resistance. High K values indicate sparse vegetation density or open water (low vegetation index), resulting in low vegetation resistance. Low K values indicate high vegetation density (high vegetation index), resulting in high vegetation resistance independent of vegetation and flow type. This manuscript describes a field experiment and discusses the relationship between K and the vegetation index (representing vegetation density). Part II will present the consequences of water movement on P retention in these systems.

Published: January 2025

In this study, we analyzed the effectiveness of a data visualization tool (dashboard) designed to provide insights to decision-makers about the vulnerability of water resources in the tri-national Upper Lempa River Basin (CARL) in the face of future climate and land use uncertainties. The effectiveness of the dashboard was assessed using three methods: (1) a user survey for evaluating dashboard clarity, completeness, and ease of use using seven parameters proposed by Stephen Few. The result of the survey overwhelmingly indicated a positive experience when interacting with the dashboard; (2) pre- and post-use tests were used to assess knowledge acquisition. The users’ correct answers increased by an average of 35%, and incorrect answers decreased by an average of 25% for questions assessing an understanding of water demands, the effects of climate change on the basin’s water security, land use trends, and the sub-basins with the highest vulnerability in the region; and, significantly, (3) user reports on insights drawn from their interaction with the dashboard. Users drew insights on the extent to which different regions will likely experience increased vulnerability regarding water resources and on strategies that could reduce this vulnerability. The key issues that need to be addressed to ensure that the dashboard fosters greater transparency and public participation in governance and is used by decision-makers to improve the management of water resources in this watershed are the following: (1) the incorporation of user feedback and the inclusion of adaptation strategies and their impacts on the dashboard; (2) the commitment and training of a local institution to host and maintain the dashboard and to make it available to the public; (3) the engagement of decision-makers from the three countries regarding the use of the dashboard to understand future uncertainties and the potential impact of adaptation strategies on performance metrics.

Authors: Orfi Jamel , Sherif Raed , AlFaleh Musaad
Published: January 2025

This work develops a comprehensive review of the main conventional and emerging desalination processes. It presents the state of knowledge of the most known and investigated techniques, highlights their advantages and drawbacks, and draws appropriate conclusions on their respective performances from various angles including their energy consumption and efficiency, environmental impacts, reliability, and flexibility in operations. This review reveals the recent large dominance and deployment of the reverse osmosis technology in the Gulf countries, mainly in Saudi Arabia; the importance of hybridization; and the slow penetration of promising processes including membrane distillation and forward osmosis into the industrial desalination market. In addition, this work aims to develop some comparison exercises between these processes using specific criteria. A cross approach allowing an easier comparison between various desalination processes could help identify the advantages and drawbacks of each technology and select the appropriate process. Therefore, various criteria allowing a clear picture to be drawn of the performance and capabilities of the main conventional and emerging desalination processes have been proposed in the frame of sustainable development. As an illustration of this general approach from sustainability prospects and considering specific weights for each proposed criterion for the case of Saudi Arabia, a comparison exercise reveals that the superiority of reverse osmosis (RO) is confirmed. Multiple effect distillation (MED) and membrane distillation (MD) processes are potentially competitive to RO while multi-stage flash (MSF) comes last due to several drawbacks.

Authors: Al-Hamawi Hala , Davies Philip A. , Mayouf Mohammad , Nikologianni Anastasia
Published: January 2025

In refugee camps, Water, Sanitation, and Hygiene (WASH) services are essential for health and well-being, yet they face sustainability challenges in post-emergency contexts. Despite considerable research on WASH services in urban and rural areas, a gap exists in addressing sustainability within refugee camps. This study fills that gap by proposing a framework for evaluating WASH system sustainability in such settings. Through a convergent mixed methods research design, sustainability dimensions, metrics, and indicators were first identified via a literature review. These were then validated through expert interviews. The study applies a five-dimensional FIETS (financial, institutional, environmental, technical, and social) framework to assess WASH sustainability. Findings reveal that financial sustainability is the most critical dimension, followed by institutional, technical, social, and environmental factors. The research also identifies key challenges such as limited funding, political barriers, and limited water resource availability. It underscores the importance of coordinated efforts among stakeholders to overcome these obstacles and achieve long-term sustainability. This framework provides a structured approach for practitioners and policymakers to assess and improve WASH services in refugee camps, contributing to broader discourse on sustainable development and water resource management.
Dialdehyde Cellulose Fabric Membranes Enable Chemical Adsorption of Amino-Containing Dyes for Wastewater Treatment
Authors: Zhang Zhaoju , Ma Hongyang , Hsiao Benjamin S.
Published: January 2025

Dialdehyde cellulose fabric (DACF) membranes with varying degrees of oxidation were fabricated using periodate oxidation and were employed for the chemical adsorption of amino-groups containing dyes from wastewater. The aldehyde group contents of DACF membranes were adjusted by altering oxidation time, which was confirmed by titration experiments. The chemical structure and morphology of DACF membranes were characterized using ATR-FTIR, TGA, SCA, SEM, XPS, and XRD measurements. The optimized DACF membrane, which was treated for an oxidation time of 24 h and has an aldehyde content of 2.97 mmol/g, was used for the chemical adsorption of amino-containing dye molecules. This process relies on the Schiff base reaction between the amino groups of the target dye molecule and the aldehyde groups of the membrane. Two typical cationic dyes, fuchsin basic and chrysoidine, containing aromatic amino groups, were chosen to determine the adsorption capacity of the DACF membrane. The adsorption kinetics, isotherms, and thermal dynamics of the DACF membrane were investigated comprehensively, while both pseudo-first- and pseudo-second-order kinetics models fit well, indicating the complicated chemical/diffusion adsorption process, where the hydrophobic properties of the DACF membrane retarded the adsorption rate. The maximum adsorption capacities of the DACF membrane against fuchsin basic and chrysoidine were 108.69 and 46.29 mg/g, respectively, as determined by Langmuir isotherm simulations. Various competing ions such as Na+, Ca2+, Cl−, and SO42− at high concentrations of 10,000 ppm were used to challenge the adsorption capability of the DACF membrane, with negligible effects observed. A new adsorption mechanism based on chemical/diffusion interaction was proposed. Bovine serum albumin (BSA), fuchsin basic, and chrysoidine were mixed to simulate the multicomponent wastewater containing dissolved organic nitrogen (DON) and demonstrated the adsorption process; the direct adsorption capacity of the DACF membrane was up to 63.0%. This work offers a new method for the highly efficient removal of organic pollutants by a chemical reaction approach.
Quantile-Based Approach for Improving the Identification of Preferential Groundwater Networks
Authors: Schiavo Massimiliano
Published: January 2025

Identifying preferential paths for groundwater flow is one of the basics for understanding aquifer systems. Shallow free-surface aquifers often have flow directions (locally) similar to those of their surface counterparts, especially if surface and groundwater bodies are directly connected. This work proposes a novel and simple framework to improve the identification of Preferential Groundwater Networks in free-surface aquifers. This is possible by proposing a quantile mapping procedure borrowed from stochastic hydrology, usually employed to adjust rainfall simulations (for example, achieved via climate models) upon available gauge-based data. This well-known procedure is applied to redistribute simulations of the aquifer bottom elevation for a real case study in Lombardy, Northern Italy. The result is a spatial redistribution of the elevation quantiles that leads to aquifer bottom surfaces carved with Preferential Groundwater Networks that are spatially consistent with the surface river network. This way, groundwater flow directions are redistributed to mimic their surface counterparts, but aquifer bottom elevations and slopes are far gentler as they were previously simulated from borehole data information. Furthermore, the errors in the spatial reframing of borehole data and the discrepancy of variogram structures before and after the redistribution procedure are not dramatically dissimilar.
Evaluating Agro-Based Waste Materials for Cyanotoxin Sorption for Future Incorporation in Nature-Based Solution Units (NBSUs)
Authors: Bavithra Guna , Azevedo Joana , Campos Alexandre , Almeida C. Marisa R. , Carvalho Pedro N.
Published: January 2025

Toxic cyanobacterial blooms are a growing environmental problem, persisting in freshwater bodies globally, and potentially hazardous to populations that rely on surface freshwater supplies. Nature-based solution units (NBSUs) are effective and sustainable approaches for water treatment, with sorption being an important process. The purpose of this study was to evaluate unmodified agro-based waste materials (rice husks, olive pulp pomace pellets (OP), cork granules) and the benchmark NBSU substrates (biochar, light expanded clay aggregate (LECA), and sand) for their microcystin-LR (MC-LR) and cylindrospermopsin (CYN) sorption potential. The kinetics and sorption mechanism of the two best sorbent materials were studied for future incorporation into NBSUs. Pre-screening of the sorbents showed highest sorption with biochar (>86% MC-LR and >98% CYN) and LECA (78% MC-LR and 80% CYN) and lower sorption with rice husk (<10%), cork (<10%), and sand (<26%). Leaching from OP made them unsuitable for further use. The sorption of both the cyanotoxins onto biochar was rapid (8 h), whereas onto LECA it was steadier (requiring 48 h for equilibrium). The pseudo-second-order kinetic model fit the sorption of both cyanotoxins onto biochar and LECA (R2: 0.94–0.99), suggesting that the sorption rate is limited by chemisorption. The sorption of MC-LR and CYN to biochar and LECA fit the Freundlich and D–R models better, suggesting multilayer sorption, high heterogeneity, and porosity in the sorbents (which was also confirmed by SEM/EDS). The sorption capacity was observed to be higher for biochar (Kf: MC-LR = 0.05, CYN = 0.16) than LECA (Kf: MC-LR = 0.02, CYN = 0.01).

Одним из важнейших условий устойчивого развития молочного животноводства является системный подход к формированию модели нормированного кормления продуктивных животных. Особое внимание при этом должно быть направлено на оптимизацию и контроль полноценности питания. В одном из сельхозпредприятий Вологодской области при применении общепринятых методик в животноводстве изучены качественные характеристики кормов, система рационов, физиолого-биохимический статус коров. Установлено, что оно располагает достаточным набором кормов для разработки рационов, обеспечивающих физиолого-биологические потребности у высокопродуктивных молочных коров. Последовательность процесса, формирующего модель полноценного кормления с использованием адресных рационов, высокоэффективных кормов и подкормок с учетом биохимических показателей крови коров, биоценоза рубца позволит сельскохозяйственным предприятиям увеличить молочную продуктивность до 5—10%.

One of the most important tasks of sustainable development of dairy cattle breeding is a systematic approach to the formation of a model of normalized feeding of productive animals. Particular attention should be paid to optimization and control of nutrition adequacy. We studied the qualitative characteristics of forages, ration system, physiological and biochemical status of cows using generally accepted methods in animal husbandry. We have established that the agricultural enterprise of the Gryazovetsky district of the Vologda Region has a sufficient set of forages for the development of rations that provide physiological and biological needs of high-yielding dairy cows. The sequence of the process forming the model of high-grade feeding with the use of targeted rations, high-efficiency forages and supplements taking into account biochemical indicators of cows’ blood, rumen biocenosis will allow agricultural enterprises to increase milk productivity up to 5—10%.

В опытах на 3 группах новотельных половозрелых коров, по 10 голов в каждой, с живой массой 560—610 кг и удоем за предыдущую лактацию 6,5—8,2 тыс. кг, изучено влияние скармливания дополнительно к основному рациону белковой и энергетической добавок на протяжении 60 дней. Группа I (контрольная) на протяжении всего эксперимента получала основной рацион, по нормам обменного протеина исходя из текущей продукции молочного белка. Коровы II и III опытных групп дополнительно к основному рациону получали: 0,5 кг белковой добавки на основе смеси соевого жмыха и подсолнечного шрота, подвергнутых тепловой обработке (II группа) для повышения уровня обменного белка на 10% и 0,5 кг зерновой смеси (III группа) для повышения уровня ОЭ, сопоставимого с этим показателем во II группе. Сравнивали удой по группам за текущую и предыдущую лактации. По сравнению с контролем, он увеличился на 11% во II группе и на 7% — в III. Различий в качестве молока, параметрах рубцового пищеварения и общем физиологическом состоянии между показателями животных всех групп установлено не было. Полученные данные могут быть использованы для разработки методик оценки полноты реализации молочного потенциала коров и новых способов поддержания высокой продуктивности при сохранении физиологического гомеостаза животных и качества молока.

In experiments on 3 groups of newly calved sexually mature cows, 10 heads per group, with a live weight of 560—610 kg and milk yield for the previous lactation of 6.5—8.2 thousand kg, the effect of feeding protein and energy supplements in addition to the main ration for 60 days was studied. The first group received the main ration throughout the experiment, according to the norms of exchangeable protein based on the current production of milk protein. Cows of the 2nd and 3rd groups received 0.5 kg of the protein supplement based on a mixture of soybean meal and sunflower meal subjected to heat treatment to reduce protein breakdown (2nd group) in addition to the main ration to increase the level of exchangeable protein by 10% and 0.5 kg of grain mixture (3rd group) to increase the level of ME comparable to that of the 2nd group. Milk yields were compared by groups for the current and previous lactations. Milk yield in the experimental groups increased compared to the control group: by 11% in the second group and by 7% in the third. No differences in milk quality, rumen digestion parameters, or the general physiological state of cows were found between the groups. The data obtained can be used to develop methods for assessing the full realization of cows' milk potential and new ways to maintain high productivity while maintaining physiological homeostasis of animals and milk quality.
Mindful Music Instruction as a Strategy for Music Listening
Authors: Obja-an John Roger A.
Published: January 2025

The purpose of the study was to describe how mindful music instruction strategy helps in the assessment of music listening skills and how it makes the students understand and appreciate western classical music. Mindful music instruction is a concept as described by Anderson (2016) and Langer (2016) where constructs of mindfulness can be done thru direct instruction to the listener. Creative Music Listening Response by Kratus (2017) was used to describe successful music responses. Quantitative and qualitative descriptive research methods were used. The study was implemented to nineteen (n=19) all girls’ school in the Philippine capital. Mindful music instruction was given before listening to music selections which range from classical to romantic styles. Findings show that the students described a clearer image/emotion/story of the music with thorough explanations from beginning to end. These images/emotions/stories were well supported with descriptions of musical elements although accuracy and consistency of the terms needs to be given attention. The summary of scores of each student showed that seven had proficient level of music listening response while twelve have advanced level. Results of student self-assessment checklist, self-reflection and interview validated the facts of the findings as students show more appreciation and understanding of western classical music and become more aware and attentive to the music they listen to. Results of students’ checklist seem to agree on the inaccuracy of using musical elements. Recommendations were given in the further use of mindful music instruction in music education in different settings, across different levels.

فكرة البحث الرئيسة تتمحور حول بيان أخلاقيات الروبوتات الجراحية وفق التأصيل الشرعي لطبيعتها، وتكمن أهمية البحث في ضرورة انعكاس أخلاقيات مهنة الطب على الروبوتات الجراحية وفق ضوابطها الشرعية، إذ إن إشكالية البحث تدور حول الإجابة عن أخلاقيات الروبوتات الجراحية التي تضبط استخدامها من الوجهة الشرعية في ظل اختلاف أراء القانونيين في تحديد طبيعتها من جهة وفي تنظيم آثار استخدامها من جهة أخرى. ولذا يهدف البحث إلى بيان الأخلاقيات اللازم توافرها في الروبوتات الجراحية من جهة، وبيان ضـوابط استخدام الروبوتات الجراحية من جهة أخرى على ضوء المقاصد الشرعية وفق الشرعية.  وقد اعتمد البحث على كل من المنهج الوصفي في تحديد مصدر الأخلاق في النظر الشرعي، والمنهج الاستقرائي لبيان الموقف الشرعي من الروبوتات الجراحية بناء على التصور الإسلامي للكون والحياة. والمنهج التحليلي لتحديد الأخلاقيات الحاكمة لبرمجة الروبوتات الجراحية من جهة، وضوابط استخدامها من جهة أخرى وذلك على ضوء المقاصد الشرعية. وقد انتهى البحث إلى عدد من النتائج من أهمها : ضرورة أن يُراعى في الأخلاقيات الحاكمة لبرمجة الروبوتات - وباتباع استخدامها -؛ التصور الإسلامي للإنسان والكون والحياة المستند إلى التوحيد والإيمان بالله وفي كون الإنسان خليفة الله على الأرض من جهة، ومفهوم المنفعة والمصلحة بمعناها وضوابطها الشرعية من جهة أخرى. ولذا أوصى البحث في ختامه بضرورة سن التشريعات اللازمة التي تنظم برمجة واستخدام الروبوتات الجراحية وفق الضوابط الشرعية العامة للعمليات الجراحية الروبوتية من جهة و وفق التصور الشرعي لطبيعتها من جهة أخرى.
The 50-Year CO₂ Balance: Crucial Roles of Agriculture, Forestry and the Ocean
Authors: Muller-Feuga Arnaud
Published: January 2025

CO₂ exchanges between continents, oceans and atmosphere are analyzed over the last 50 years, correcting for the importance of agriculture and forestry. To do this, we simply considered their commercial production statistics and their 40 to 50% of dry weight carbon content. These vital activities have captured on average 39.9 GtCO₂/year from the atmosphere over the last decade. This carbon capture and storage (CCS) by plants has more than doubled since 1970 and compensated for 36.0 GtCO2/year of fossil emissions. After mineralization by respiration and combustion, the carbon mobilized in those biomasses returned to the atmosphere as CO2 . This release, which takes a quarter of a century after harvest on average, has stabilized at around 10.2 GtCO₂/year over the last half-century, leading to a continental balance, including the combustion of fossil hydrocarbons, of 6.8 GtCO₂/year emitted on average. Contrary to what is generally accepted, CCS by plant cultivation has completely offset emissions from the combustion of fossil hydrocarbons. As a result of this new balance, the ocean appears to have been an increasingly important source of CO₂, going from neutral in the 1970s to an average of 10.6 GtCO₂/year over the last decade. Over the half-century, the ocean has contributed 52% to the increase in atmospheric CO₂ concentration, with the remainder coming from the continents

Лимфатические узлы - это небольшие железы, необходимые, для фильтрации жидкости из лимфатической системы. Лимфаденопатия - это пальпируемое увеличение лимфатического узла диаметром более 1 см. Этиология включает в себя инфекционные и аутоиммунные заболевания, злокачественные новообразования, лимфопролиферативные нарушения, прием определенных лекарственных препаратов. Лимфаденопатии могут быть генерализованными и локализованными. Зачастую, пациенты не знают об увеличении лимфоузлов, и лимфаденопатия выявляется врачом при объективном осмотре. Генерализованная лимфаденопатия, с поражением 2-х и более групп лимфатических узлов, может указывать на основное онкологическое или системное заболевание. В статье представлен случай генерализованной лимфаденопатии неизвестной этиологии, которая сопровождалась полисерозитом и другими клиническими проявлениями, указывающими на наличие основного онкологического или системного заболевания.

Lymph nodes are small glands needed to filter fluid from the lymphatic system. Lymphadenopathy is a palpable enlargement of a lymph node with a diameter of more than 1 cm. Etiology includes infectious and autoimmune diseases, malignant neoplasms, lymphoproliferative disorders, and taking certain medications. Lymphadenopathy can be generalized and localized. Often, patients are unaware of enlarged lymph nodes and lymphadenopathy is detected by a doctor during an objective examination. Generalized lymphadenopathy, with lesions 2 or more groups of lymph nodes may indicate an underlying cancer or systemic disease. The article presents a case of generalized lymphadenopathy of unknown etiology, which was accompanied by polyserositis and other clinical manifestations indicating the presence of an underlying oncological or systemic disease.

The Taming of the (Post)Modern Shrew in Literature and on Stage
Authors:   aculty of Letters, Alexandru Ioan Cuza University, PETRARU Ana-Magdalena
Published: January 2025

The present paper aims to analyse the postmodern Shakespearean shrew from Anne Tyler’s bestseller Vinegar Girl and this year’s staging at the Athenaeum in Iasi, Romania. The former is a modern adaptation, while the latter preserves the Italian setting with music and dance inserts from our time. Testifying to the imagination of the novelist/stage director, the texts show once more the immortality of Great Will’s genius and the need to update his plays for contemporary audiences.
The Intersection of Theatre, Motion Capture, and Digital Avatars Exploring New Horizons in Children's Theatre
Authors:   Theatre and Film Faculty, Babeș-Bolyai University, Cluj-Napoca, MATEI Cosmin
Published: January 2025

The integration of Motion Capture (MoCap) technology and digital avatars into children’s theatre offers transformative potential for both artistic innovation and educational development. These technologies enable immersive, dynamic performances that captivate young audiences while introducing new forms of storytelling. However, they also present challenges regarding emotional manipulation and the erosion of authentic human connection. MoCap complicates the traditional actor-audience relationship, as digital avatars assume increasingly active roles in shaping the narrative. This article critically examines the role of MoCap and avatars in reshaping children’s theatre, drawing insights from two interviews with a theatre professional and a tech entrepreneur. The interviews explore the implications of these technologies on performance ownership, identity, and the blurred boundaries between human and digital expression. Additionally, the paper discusses how the integration of MoCap into educational environments is essential for preparing actors and audiences to engage responsibly with these innovations. Ultimately, the article argues for a balance between creative exploration, ethical considerations, and the critical engagement of both performers and spectators in a digitally evolving theatrical landscape.
The Psychological Gesture in The Theater of Animation - Case Study of the Performance The Butler Directed by Ciprian Hușanu
Authors:   Faculty of Theatre, George Enescu National University of Iași, PETCU Ioana
Published: January 2025

Animated theater uses, when directorially appropriate, theories and methods from dramatic theater. In this article, we aim to find the landmarks of the psychological gesture, a method of theatrical pedagogy initiated by Michael Chekhov, in animated theater performances. In this sense, we analyze the show The Butler, an adaptation of the novel The Remains of the Day by Kazuo Ishiguro, a production of the Faculty of Theater and the Synchret Company, from 2024. Following the director's (Ciprian Huțanu) message about a society with its declining customs, in the troubling historical context of the beginning of World War II, we detect how key principles of psychological realism or psychological gesture are involved in the animated spectacle. The intersection between the bunraku style adapted to the European stage, the scenic image, the sound universe build a cohesive production that appeals to the viewer's affective memory, creating emotional and powerful moments.
