title: EXPLORING ACTIVATION ENERGY EFFECT ON NON-DARCY HYDROMAGNETIC CONVECTIVE HEAT AND MASS TRANSFER FLOW OF THERMALLY RADIATING ETHYLENE GLYCOL BASED TIO2 AND AG NANOFLUIDS IN CYLINDRICAL ANNULUS WITH THERMO-DIFFUSION
description: An examination was carried out by analyzing the movement of water-titanium dioxide and silver nanofluids in a coordinate annulated zone while being subjected to the impact of heat sources for non-uniform. The non-linear equations have been explained by employing quadratic polynomials and the Galerkine finite detail technique. Both of these methods have been successfully utilized. When analyzing different parametric values, it has been shown that greater temperatures and concentrations are created with lower velocities, whereas larger velocities are produced with higher radiative heat flux (Rd)/ nanoparticle volume fraction (f). This phenomenon has been seen for a significant number of parameters.

THE AMHARIC VERSION OF THE WARWICK-EDINBURGH MENTAL WELL-BEING SCALE: THE PSYCHOMETRIC PROPERTIES AND FACTOR STRUCTURE
type: item
description: Purpose: This study aims to assess the psychometric evidence and factor structure of the Amharic version of the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) for use in Ethiopia, addressing the theoretical, cultural, and empirical limitations encountered by the English version. Method: This study utilized a cross-sectional design and collected data from 474 individuals selected from the general population through stratified sampling. The participants included bankers, merchants, laborers, and employees from government institutions. The data were analyzed via SPSS 27 and AMOS 23. Internal consistency reliability and temporal reliability were assessed via Cronbach’s alpha and the test‒retest method, respectively. Exploratory factor analysis (EFA) was performed to identify the factor structure of the scale. Confirmatory factor analysis (CFA) was performed to test whether the observed items accurately loaded onto mental well-being (MW), providing model fitness to ensure theoretical expectations and empirical evidence. Additionally, CFA also provides average variance extracted (AVE) to evaluate discriminant and convergent validity. Results: The scale exhibited internal consistency (r=0.87) and temporal reliability (r=0.89). The EFA revealed a three-factor structure for the WEMWBS-Amharic, comprising 1: Spiritual, 2: Eudaimonic, and 3: Hedonic factors, which accounted for 52.365% of the total variance. The scale retained 21 out of 24 items. CFA validated the structural integrity of the factors within the WEMWBS-Amharic, with indices showing CMIN/DF = 2.088; RMSEA = 0.048; and GFI, AGFI, NFI, RFI, IFI, TLI, and CFI all exceeding 0.90. Both convergent validity (AVE = 0.51 to 0.55) and discriminant validity (√AVE > correlation matrix) were established. The participants demonstrated moderately low levels of social desirability compared with those observed in the original WEMWBS. Conclusion: The WEMWBS-Amharic has shown an acceptable level of validity and reliability for …

FINANCIAL RESOURCE MANAGEMENT PRACTICES THAT ENHANCE QUALITY EDUCATION IN HIGHER EDUCATION: INSIGHTS FROM SOUTHERN ETHIOP
type: item
description: Financial management is a vital tool in the operations of public universities, enabling them to navigate the rapidly changing external environment that impacts the quality of education. However, universities face various technical challenges in the financial system, which hinder overall institutional sustainability, particularly in academics, student support, and research and community service. Consequently, this study examined the linkage between financial management practices and the quality of education in higher education in Southern Ethiopia. The study employed an explanatory research design and collected data from 117 university staff. The study used both descriptive and inferential statistics (correlation and multiple linear regression) to analyze the data. Results revealed that the financial management practices were moderately effective in achieving education quality. Results showed that the internal control systems, budgeting, and financial reporting provide a reliable measure of quality education. Key issues were linked to inadequate financial resources, the bureaucratic nature of operations, and inadequate attention to students’ diverse needs. Key areas of importance include identifying financial risks and corruption in the allocation of financial resources, which undermine the provision of quality education.

SUSTAINABLE GREEN PRODUCTION MODEL FOR CARBON EMISSION AND RECYCLING PRODUCTIVITY IN CIRCULAR ECONOMIC OPTIMIZATION
type: item
description: This study develops a mathematical model for sustainable production inventory management, focusing on carbon impact and recycling in a two-stage production setting. The novel model is based on three perspectives: (a) a sustainable economic production model under carbon emissions from manufacturing and inventory storage, (b) a sustainable economic production model that incorporates the process of recycling and disposal, and (c) circular economic optimization that promotes carbon emissions and recycling. The main objective of this research is to optimize the total cost function and address environmental concerns related to green products. The optimal total cost function, production setup costs, holding costs, screening costs, rework costs, carbon emission costs, and recycling costs are calculated. Managerial insights highlight the importance of effectively managing reusable items and ensuring proper disposal to support environmental sustainability and maintain a circular economy. A numerical example is used to verify the realism of the proposed model in the prediction of cost-effectiveness and visualization via MATLAB software. The sensitivity analysis indicated the importance of reducing production-based carbon emissions and improving recycling levels to minimize the total cost function in the path to enhancing the sustainable environment.

CHILD MALNUTRITION AND SPATIAL ANALYTICS: A COMPREHENSIVE REVIEW OF LITERATURE AND RESOURCES
type: item
description: Background Child malnutrition remains a critical public health challenge, particularly in low and middle-income countries (LMICs), where it contributes to high rates of morbidity, mortality, and long-term developmental impairments. Traditional national-level statistics often obscure significant geographic disparities within countries. Spatial analytics has emerged as a transformative approach to uncovering these hidden patterns and informing more targeted and effective nutrition interventions. Methods This review synthesizes academic literature, including peer-reviewed articles, theses, and books, that apply spatial analysis techniques such as Geographic Information Systems (GIS), spatial regression, and cluster detection to the study of child malnutrition. It also reviews open-access data sources, including Demographic and Health Surveys (DHS), UNICEF's Multiple Indicator Cluster Surveys (MICS), and global nutrition databases, which enable the spatial mapping and analysis of malnutrition patterns. Results Studies from various countries, including India, Ethiopia, Bangladesh, Uganda, Peru, and the Philippines, demonstrate the effectiveness of spatial analytics in identifying malnutrition hotspots, understanding spatial clustering, and revealing regional variations in the impact of risk factors such as poverty, maternal education, sanitation, and environmental conditions. These insights support the development of geographically nuanced public health strategies and interventions. Conclusion The review emphasizes the need to maximize the impact of spatial analytics in addressing child malnutrition by strategically investing in data systems, strengthening capacity, and integrating spatial tools into health and nutrition programs. A multidisciplinary approach that bridges nutrition science, geography, data science, and public health is crucial for translating spatial insights into targeted, evidence-based interventions, especially in diverse and resource-constrained cont…

ENERGY SECURITY INDEX FOR G20 MEMBERS BASED ON THREE DIMENSIONS: HEALTH, ENVIRONMENT, AND DIVERSITY
type: item
description: G20 members are the strongest economies of the world and thus represent global important features and trends of the energy security. Since energy security is an important concept in global settings of energy systems, numerical measures are needed in order to represent the circumstances with meaningful numbers. Therefore, this study aims to conceptually and methodologically construct an energy security (ES indexH,E,D) index based on three dimensions: Health, Environment, and Diversity, with an application on the G20 members. The results clearly show how this index is constructed and show its application on the G20 members. The conclusions provide policymakers with an opportunity to adopt this index in their analysis of energy security, as it gives insights about energy systems and how to achieve higher energy security. For example, adopting clean renewable energy technologies to reduce the death rate attributed to cancer and to reduce GHG emissions are among the recommendations.

CYTOTOXICITY OF NANOPARTICLES ON LIVING CELLS
type: item
description: Nanotechnology, a cutting-edge field, leverages nanoparticles (NPs) with dimensions less than 100 nanometers to revolutionize various industries. These particles exhibit unique physical, chemical, and biological properties, making them integral to advancements in agriculture, engineering, healthcare, and research. However, their widespread use raises critical concerns about potential cytotoxic effects on human health and the environment. Nanoparticles are broadly classified into organic, inorganic, and carbon-based types, synthesized using techniques such as sol-gel methods, spinning disc reactors, and biological processes. Advanced characterization tools like scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are essential for understanding their size, shape, and surface properties, which influence their reactivity and applications. Despite their versatility, nanoparticles often pose toxicity risks due to mechanisms like reactive oxygen species (ROS) generation, mitochondrial damage, and DNA disruption. Metalbased nanoparticles, such as zinc oxide (ZnO) and titanium dioxide (TiO₂), have been shown to induce oxidative stress and inflammation, while carbon-based nanoparticles can interfere with cellular processes. These effects are highly dependent on particle size, shape, and surface charge, which modulate interactions with biological systems. The cytotoxicity of nanoparticles underscores the importance of rigorous safety evaluations and long-term studies to mitigate their risks. By addressing these challenges, researchers can optimize the use of nanoparticles in innovative applications, ensuring their benefits outweigh potential harms. The continued exploration of safer synthesis techniques and thorough toxicity assessments is crucial for balancing the promise of nanotechnology with its implications for health and the environment.

A PANDEMIA PELA COVID- 19 E A VIOLÊNCIA SEXUAL CONTRA AS MULHERES: ANÁLISE ESPACIAL E TEMPORAL DOS ESTUPROS EM PERNAMBUCO, BRASIL
type: item
description: A violência sexual e o estupro são ataques ao corpo e à dignidade de uma mulher; tais agressões têm consequências psicológicas, sociais e econômicas para o resto de sua vida. A pandemia pela COVID-19 expôs e exacerbou as desigualdades dentro dos países, com a maior vulnerabilidade das mulheres a violência doméstica, sexual e feminicídios. Este estudo objetivou analisar a tendência temporal das taxas de estupro contra as mulheres em Pernambuco, no período pré-pandêmico e pandêmico. Foram registrados 8.948 estupros contra as mulheres no período, com 5.076 (56,7%) ocorridos no pré-pandêmico. No período pandêmico observou-se redução nas taxas de estupro contra as mulheres na população adulta e na Região Metropolitana. As reduções na taxa de estupro contra as mulheres encontradas, podem refletir a subnotificação na pandemia, além do estigma, medo, vergonha e culpabilização das vítimas.

COMPARATIVE EFFICACY OF ANTIHYPERTENSIVE DRUGS AMONG ADULTS WITH CHRONIC KIDNEY DISEASE IN A TERTIARY CARE HOSPITAL
type: item
description: Background: Hypertension (HTN) is a leading contributor to chronic kidney disease (CKD) globally and a significant modifiable risk factor for both cardiovascular and renal complications. Effective blood pressure (BP) control is essential in managing CKD, yet the comparative efficacy of different antihypertensive agents remains an area of active research. Objective: To evaluate and compare the antihypertensive efficacy of telmisartan and amlodipine in adult patients with CKD attending a tertiary care hospital. Methods: A prospective, randomized, comparative study was conducted over a six-month period involving 88 hypertensive patients with CKD. Participants were randomized into two groups: Group A received telmisartan 40 mg once daily, while Group B received amlodipine 10 mg once daily. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded at baseline and after six months. The primary endpoint was the mean change in SBP and DBP. Data were analysed using Student’s t-test, with a p-value of <0.05 considered statistically significant. Results: Both treatment groups exhibited significant reductions in BP from baseline. However, telmisartan was associated with a more pronounced reduction in SBP (−30.9 ± 7.4 mmHg vs −2.0 ± 8.5 mmHg, p = 0.0424) and DBP (−21.9 ± 4.1 mmHg vs −2.2 ± 6.3 mmHg, p = 0.0148) compared to amlodipine. No serious adverse events were reported during the study. Conclusion: Telmisartan demonstrated superior antihypertensive efficacy compared to amlodipine in patients with CKD, highlighting the potential preference for angiotensin receptor blockers (ARBs) as first-line agents in this population. Further large-scale, long-term studies are recommended to validate these findings.

type: item
description: The flowers of Michelia champaca .L have been reported to possess certain benzo quinoline alkaloids. Thus, this study was aimed at the anti-arthritic potential and phytochemical screening of two important compounds CMPK-1, tetrahydro benzodioxolo benzo quinolin and CMPK-2, tetrahydro benzodioxolo benzo quinolin-16-ol (alkaloids) of flowers of Michelia champaca from with nHexane fractions of petroleum ether extract. Isolated alkaloids was identified and characterized by chemical tests, M.P., TLC, paper chromatography and spectroscopic methods like UV, Visible, FT-IR, 1HNMR, 13CNMR and Mass spectroscopy. The anti-arthritic activity of the isolated alkaloids were also investigated against standard Diclofenac sodium by Carrageenan induced arthritic in rats. The results demonstrated shows significant anti-arthritic activity of isolated compounds at a dose of 500 mg/kg body weight might prove efficacious for further design and development of agents with significant biological activity. Hence, isolation was done with petroleum extract. Isolated alkaloids CMPK-1 and CMPK-2 may be one of the components responsible for the observed anti-microbial activity of the flowers.

SPECTRAL DECOMPOSITION OF FRACTIONAL SWIFT–HOHENBERG EQUATIONS USING THE FRACTIONAL FOURIER TRANSFORM
type: item
description: This paper introduces a spectral decomposition framework for addressing time–fractional Swift–Hohenberg (S–H) equations through the use of the Fractional Fourier Transform (FrFT). In contrast to classical transforms such as Laplace or Elzaki, the FrFT offers a more versatile spectral mechanism that bridges time and frequency domains, enabling an effective diagonalization of differential operators. Building on this idea, we propose the Fractional Fourier Transform Decomposition Method (FrFT–DM), which integrates the spectral features of FrFT with decomposition strategies to derive convergent series solutions for both linear and nonlinear fractional Swift–Hohenberg models. The theoretical foundation of the method is supported by rigorous results on existence, uniqueness, and convergence, along with a precise truncation error estimate. To ensure stability and boundedness, several new lemmas and corollaries are established, providing spectral justification for the approach. The effectiveness of the method is illustrated through six representative examples, encompassing both linear and nonlinear cases of the Swift–Hohenberg equation. Numerical simulations demonstrate that the approach accurately captures the solution behavior across various fractional orders and reduces to the classical integer–order solutions as .

INVERSE SOURCE PROBLEMS FOR GENERALIZED FRACTIONAL BOUNDARY VALUE MODELS WITH AB–CAPUTO LAPLACIAN OPERATORS
type: item
description: This paper investigates two classes of inverse source problems associated with multi-parameter space–time fractional boundary value models involving the Atangana–Baleanu–Caputo (ABC) Laplacian operator. The first model concerns the recovery of a space-dependent source term from over-specified final data, while the second model addresses the reconstruction of a time-dependent source factor from additional integral conditions. A sequence of lemmas establishes the analytical properties of the generalized fractional kernels and their Laplace representations. Building on these results, existence, uniqueness, and ill-posedness theorems are derived for both inverse models under appropriate regularity assumptions. Several illustrative examples demonstrate how the theoretical framework can be applied to recover unknown sources in boundary value problems with fractional dynamics. The results highlight the flexibility of ABC-based operators in capturing memory effects and offer a foundation for future numerical schemes and practical applications in anomalous diffusion, viscoelasticity, and related fields.

INFLUENCE OF PRINCIPALS' LEADERSHIP BEHAVIOR ON SCHOOL PERFORMANCE: A CASE STUDY IN THE SECONDARY SCHOOLS OF THE SOUTH REGION, ETHIOPIA
type: item
description: This study was designed to investigate the influence of principals' leadership behavior on school performance in Secondary Schools of the Southern Region in Ethiopia. The problem addressed in the research was the effects of principals' leadership behavior on the school performance. The main research question that guided this study was: How does the principals' leadership behavior influence the performance of government secondary schools in the Southern region of Ethiopia? A qualitative method, using a case study design was employed with analyzing documents, observation and interviews as a means of data collection. Through face-to-face and semi- structured, open-ended in-depth interviews with 30 participants, the researcher revealed personal views of principals' leadership behavior on school performance. Principals used the autocratic as well as the democratic and laissez-faire styles depending on school performance. With increasing educational qualifications the employees exhibit more of the democratic leadership tendencies and those who are educated less are inclined towards the autocratic leadership style. The lack of a compelling vision and mission for government schools continues to be a major obstacle in any effort to improve schools. It was developed as a strategy that the principals were well equipped with knowledge and skills in management and leadership to transform the Secondary Schools of the Southern Region of Ethiopia.

BUILDING A SUSTAINABLE AND ENERGY-EFFICIENT GREEN HYBRID CLOUD USING DIGITAL TWIN
type: item
description: The exponential growth of cloud computing has reshaped global information and communication technology (ICT) infrastructures. However, the energy demands of cloud services and associated carbon emissions pose significant challenges to sustainability. Hybrid cloud models, which integrate private and public resources, provide flexibility but introduce orchestration, reliability, and efficiency complexities. This paper proposes a comprehensive framework for designing and deploying a Sustainable and Energy-Efficient Green Hybrid Cloud using Digital Twin (DT). The methodology integrates carbon-conscious provider selection, Green Resource Broker Management Systems (GRBMS), fault tolerance modeling, load balancing, and scheduling via SYL’s Algorithm. Additionally, it presents energy measures like the Clean Energy Index (CEI) and Power Usage Effectiveness (PUE), which are assessed using DTMC (Discrete-Time Markovian Chain) modeling and the GreenCloud Simulator. Experimental simulations on Indian cloud infrastructure patterns show that software optimization can reduce emissions by 41.63%, with hardware optimization yielding an additional 58.37%. Comparative results across ordinary cloud, green cloud, hybrid cloud, and green hybrid cloud deployments highlight the superior efficiency of Digital Twin–enabled orchestration. The findings suggest that integrating DT models with hybrid cloud architectures can significantly enhance sustainability while maintaining service reliability and performance.

THE USE OF BACKWARD DESIGN IN TECHNICAL ENGLISH COURSES FOR ENGINEERING STUDENTS
type: item
description: Pedagogical practices in Spain maintain a traditional format in which the teacher is revealed as the neural axis of the teaching-learning process. This limits the students to a passive role in which they merely reproduce the knowledge transferred without contributing new knowledge through critical, reflective and transformative postures. The national reality demands a modern preparation framed in computational knowledge that can satisfy the current needs that demand a good computer management, without forgetting that the use of new Information and Communication Technologies (ICTs) must be a cornerstone. Added to this reality is the fact that teachers are not totally updated in the use of ICTs, in many cases due to a lack of interest in self-training and in other cases due to the neglect of the relevant bodies. The general objective of this research is to propose the application of the backward design method in an English course in a technical engineering degree in a Spanish university to develop the understanding and transfer of what has been learned in the English subject.

EXPERIMENTAL INVESTIGATION ON WASTE MATERIALS (RECYCLED BRICK AND CONCRETE DUSTS) TO BE USED AS SAND SUBSTITUTES
type: item
description: Concrete is among the most utilized construction materials. Fine aggregate is one of the most crucial elements of concrete. Sylhet sand is frequently utilized as a fine aggregate in the manufacturing of concrete in Bangladesh. Due to a lack of access to the river sand throughout the year, an alternate substance for usage as sand in construction work is required. Recycled brick and concrete dust are two examples of alternatives that can be utilized in construction to partially replace sand. Concrete's compressive strength is determined by its coarse and fine aggregate characteristics. This study aims to examine potential applications for the use of recycled brick and concrete dust as fine aggregates in concrete mixes. In this study, cylindrical concrete specimens have been prepared using Sylhet sand with the replacement of various percentages of recyclable brick and concrete dust as fine aggregates. The concrete mix ratio was 1:1.5:3, and the w/c ratio was kept at 0.5. These specimens were investigated after curing to determine their compressive strength. The concrete's compressive strength was confirmed to be decreasing as a result of the tests when Sylhet sand was replaced with 25%, 50%, 75%, and 100% recycled brick and concrete dust.

RISK ASSESSMENT AND HAZARD MANAGEMENT IN WATER TREATMENT: A CASE STUDY OF BHANDUP COMPLEX WATER TREATMENT PLANT, MUMBAI
type: item
description: Water treatment facilities in India plays a vital role to public health and safety by providing safe drinking water. But these treatment facilities can be a single point of failure in the event of possible shutting down due to any reason. This research focuses on the assessment of risks conducted through Hazard Identification and Risk Assessment (HIRA) in order to assess the characteristics of potential hazards. Such hazards can be related to chemical, physical, and biological processes taking place within a water treatment plant. The present case study focuses on Bhandup Complex Water Treatment Plant, which is located in Mumbai, and has a treatment capacity of 2810 million liters per day. The study employs field observations, semi-structured interviews, analysis of historical data, and laboratory testing to establish risks at various treatment stages, namely pre-chlorination, filtration, and post-chlorination. A systematic likelihood classification that is coupled with a risk matrix enables an objective, structured assessment of possible hazards, focusing on those hazards that have both high probabilities and significant repercussions. This detailed approach emphsises on the importance of effective risk management strategies which are critical to public health protection and ensuring efficiency in operations.

IDENTIFICATION OF FRAUD PATTERNS AND INDICATORS IN VILLAGE FUND MANAGEMENT IN INDONESIA
type: item
description: This study aims to uncover patterns of fraud in village funds, in addition to identifying influencing factors, involved parties, and necessary preventive measures. Detecting patterns of fraud in village fund management is crucial for identifying practices that harm and undermine the integrity of fund utilization. This subsection reviews the efforts to detect fraud patterns in village fund management in Indonesia. The method used is a systematic literature review, and by examining 40 related journals, several patterns of village fund fraud in Indonesia have been identified, such as project price mark-ups, embezzlement of funds, fictitious projects, bogus work, financing projects from other sources, and village fund robbery. Prevention and mitigation efforts should be integrated, involving collaboration between the government, village communities, and relevant stakeholders. The government should enhance supervision over village fund utilization through internal and external audits. Village communities should also participate actively in supervising fund usage through participation in village forums.

TREE SPECIES DIVERSITY, COMMUNITY COMPOSITION, AND FOREST STRUCTURE ACROSS THE ECOLOGICAL TRANSITION ZONE LINKING THE EASTERN AND WESTERN GHATS, SOUTH INDIA
type: item
description: Transitional forest zones that link major biogeographic regions often harbor high ecological complexity and species turnover, yet remain poorly studied. This research assesses tree species diversity, community composition, and forest structure along a 68 km east-to-west ecological gradient spanning four protected areas in Karnataka, South India—Bannerghatta National Park, Cauvery Wildlife Sanctuary, MM Hills Wildlife Sanctuary, and Biligiri Rangaswamy Temple (BRT) Tiger Reserve. A total of 42 plots (20 m × 20 m) were established at 5 km intervals to record all trees with girth at breast height (GBH) >15 cm. Across the transect, 123 tree species representing 42 families were documented. Species richness and diversity indices (Shannon-Wiener H′ and Simpson’s Index) increased progressively from east to west, reflecting a transition from dry deciduous forests in Bannerghatta (25 species, H′ = 2.1) to semi-evergreen and moist deciduous forests in BRT (61 species, H′ = 3.8). Basal area and stem density showed similar trends, increasing from 12.5 m²/ha and 350 trees/ha in the drier forests to 28.7 m²/ha and 550 trees/ha in the wetter forests, suggesting older, more mature stands in the western Ghats. Dominant species varied regionally: Anogeissus latifolia and Albizia amara in dry zones; Tectona grandis in mid-zones; and Syzygium cumini, Terminalia paniculata, and Machilus macrantha in wetter zones. Importance Value Index (IVI) and family-level richness analyses highlighted Fabaceae, Combretaceae, and Rubiaceae as ecologically prominent. Statistical analyses, including ANOVA, correlation matrices, and species accumulation curves, confirmed that elevation, moisture, and forest type significantly influenced diversity and structure. These findings underscore the conservation significance of ecotonal corridors in promoting biodiversity, enhancing ecological connectivity, and supporting forest resilience across climate and disturbance gradients.

DİNLENME POTANSİYELİ VE AKSİYON POTANSİYELİ’NE GİRİŞ
type: item
description: Bu makale, "Dinlenme Potansiyeli ve Aksiyon Potansiyeline Giriş" konusunu açıklamaktadır. İnsan vücudu yaklaşık 60 trilyon (60 × 10¹²) hücreden oluşur. Bunların çoğu boyut ve şekil açısından birbirine oldukça benzerken, sinir ve kas hücreleri gibi belirgin şekilde farklı olanlar da vardır; bu hücreler oldukça uzun, ince ve makroskobik olarak görünürdür. Her hücre, tam genomik bilgiye sahip olmasına rağmen, organlar, sinirler, kaslar, beyin ve deri gibi çeşitli görevleri yerine getirir. Bu çalışmada, dinlenme potansiyeli ve aksiyon potansiyelini açıklamak için yeterli olan oldukça sadeleştirilmiş bir hücre modeli ele alınmaktadır. Aksiyon potansiyeli, reseptörler, sinir hücreleri ve kas dokularının işlevlerini yerine getirebilmesini sağlayan temel elektro-kimyasal bir süreçtir. Ancak bu potansiyelin ortaya çıkabilmesi için, öncelikle hücrelerin dinlenme potansiyeli durumunda bulunması gerekir; bu durum çalışmanın başlangıç noktası olarak incelenmektedir. Hücre zarının elektriksel potansiyelindeki değişiklikler, sinirsel ve kas faaliyetlerinin temelini oluşturan son derece düzenli ve enerjiye bağlı süreçlerdir. Dinlenme potansiyeli, hücrenin iç ve dış ortamları arasındaki iyonik dengenin korunmasıyla sürdürülen, canlılığın temel gerekliliklerinden biridir. Aksiyon potansiyeli ise, bu dengeyi kısa süreliğine bozan ancak sinyallerin iletiminde kritik rol oynayan hızlı ve geçici bir olaydır. Na⁺ ve K⁺ iyonlarının voltaj kapılı kanallar aracılığıyla membran boyunca yönlendirilmesiyle gerçekleşen bu elektriksel olaylar, yalnızca birkaç milisaniye sürmesine rağmen, organizmanın bilgi işleme kapasitesi açısından yaşamsal önem taşır. Bu süreçte, hücre zarı bir kapasitör gibi davranır; zar potansiyelinin değişimiyle birlikte elektriksel yükler birikir ya da boşalır. Hesaplamalar, dinlenme potansiyeli ve aksiyon potansiyelinin oluşması için yalnızca iyonların çok küçük bir kısmının zar boyunca geçmesinin yeterli olduğunu göstermektedir.

THERMAL & MECHANICAL DESIGN AND PRODUCTION OF A COOLING MACHINE HEAT EXCHANGER WITH THERMOPLATES FOR GRANULAR SOLIDS USING THE SOLID-LIQUID-GAS ENERGY TRANSFER MECHANISM
type: item
description: In this article, “Thermal & Mechanical Design and Production of a Cooling Machine Heat Exchanger with Thermoplates for Granular Solids Using the Solid-Liquid-Gas Energy Transfer Mechanism” is considered and explained. The mechanical and thermal design of this “Cooling Machine Heat Exchanger with Thermoplates for Granular Solids Using the Solid-Liquid-Gas Energy Transfer Mechanism” is completely original, unique and belongs to the author of this article who is Emin Taner ELMAS. He and all the technical calculations of this project also realized by him develop the technical project drawings at the conclusion section of this article. There are also original photographs of the “Cooling Machine Heat Exchanger with Thermoplates for Granular Solids Using the Solid-Liquid-Gas Energy Transfer Mechanism” which is manufactured after the thermal and mechanical design works. As it is known, granular solid materials are hygroscopic. When moisture transfers from the product to the air in the space between the granules, the humidity of the air will increase. This can cause condensation on the surface of the cold heat exchanger plates. Condensation on the plates will quickly lead to caking in the cooler. [16], [17], [18], [19] The Cooling Machine for Granular Solids Cooler is designed for long term, reliable operation without the need for regular cleaning. To achieve this, the mechanism of condensation and product caking must be prevented. To prevent condensation the dewpoint of the air in the void space of the cooler needs to be lower than the temperature of the plate exchanger. [16], [17], [18], [19] The dewpoint of the air in the heat exchanger changes relative to the temperature of the product. The relationship between dewpoint and temperature is governed by the critical relative humidity (CRH) of the cooling machine. Each cooling machine has a unique CRH characteristic. [16], [17], [18], [19] As the granular solids cools when it passes through the exchanger, the dewpoint lowers…

ASSESSMENT OF EUPHORBIA HIRTA FOR THEIR PRELIMINARY PHYTOCHEMICAL SCREENING, ANTIBACTERIAL ACTIVITY AND NUTRIENT COMPOSITION
type: item
description: Herbal drugs are amongst the oldest remedies, and India is known for her Ayurvedic treatments. Medicinal plants like Euphorbia hirta Euphorbiaceae-annual herb distributed all over India have been used in traditional medicine for the treatment of female disorders, respiratory problems, digestive troubles, and infections. Despite its immense potential, E. hirta remains one of the least promoted herbal drugs. The present study investigates the phytoconstituents, proximate composition and antibacterial activity of E. hirta was tested for antimicrobial activity against enteric pathogens and incorporated into recipes. Phytochemical screening of the aqueous extract showed the existence of flavonoids, alkaloids, polyphenols, and terpenoids for its antioxidant activities. Extracts made in ethanol were saponin-free and glycoside-free. The proximate nutrient analysis demonstrated a high calcium content in the leaf (342.03±7.01 mg) and whole plant (455.09±8.01 mg). Tested against both Gram-positive (Bacillus subtilis, Staphylococcus aureus) and Gram-negative (Escherichia coli, Proteus vulgaris) pathogens using the disc diffusion method. Results on the antibacterial assay with inhibition zone; Ethanol extract of the whole plant was more effective showing the highest inhibition zone (18.9±0.05 mm) against B. subtilis, though ethanol leaf extract showed no activity against E. coli. Recipe trials were conducted by incorporating dried E. hirta powder into foods. On the other hand, Namakpare having 9% leaf powder showed comparable performance with the standard recipe and Parantha with 3% leaf powder obtained the maximum acceptability score. It signifies that the traditional usage of E. hirta for multiple diseases having antimicrobial property and it has a potential to act as a safer and cost-effective alternative to chemical drugs. Production of natural products using E. hirta might improve the accessibility of primary healthcare services, particularly in developing regions.

ANTIBACTERIAL ACTIVITY OF WITHANIA SOMNIFERA IN COMBINATION WITH ANTIBIOTICS, AGAINST HUMAN PATHOGENIC GRAM- NEGATIVE BACTERIA
type: item
description: Phytochemical analysis of Withania somnifera was carried out using standard techniques. The plant was specifically selected due to its reported antibacterial activity against pathogenic Gram-negative bacteria and its traditional medicinal use. Environmental samples including soil, dog food, and sewage water were collected, and bacteria were isolated using Eosin Methylene Blue (EMB) culture medium. After incubation for 24–48 hrs, three Gram-negative bacteria, Escherichia coli, Enterobacter, and Klebsiella, were identified through morphological and biochemical characterization, with results validated using published literature. Plant extracts of W. somnifera were prepared and subjected to phytochemical screening, which confirmed the presence of bioactive compounds. Antibacterial Susceptibility Testing (AST) was then performed to compare the antibacterial activity of W. somnifera extracts with Ciprofloxacin, a standard antibiotic. The results revealed that W. somnifera exhibited inhibitory effects against the test isolates, although the degree of inhibition varied across bacterial species and extract concentrations. The comparative analysis demonstrated that while Ciprofloxacin showed strong activity, W. somnifera also possessed notable antibacterial potential, suggesting its possible role as a natural alternative in combating antibiotic-resistant Gram-negative pathogens. These findings support the therapeutic value of W. somnifera and highlight its potential contribution to addressing the growing challenge of antimicrobial resistance.

ASSESSING CONSUMER PERCEPTION, SENSORY ACCEPTANCE AND NUTRITIONAL COMPOSITION OF RADISH MICROGREENS
type: item
description: Purpose: Microgreens, young-tender green leafy plants, are being valued for their vibrant appearance, rich flavors and nutrient-rich profile, yet remain an underexplored area. Hence, the study was undertaken to analyze consumer perception towards microgreens, as well as to evaluate the sensory characteristics and nutritional composition of three microgreen varieties (white, purple, and pink radish). Methods: A pre-tested online questionnaire was used to assess consumer awareness and perception using 610 respondents aged 20-35 years. To identify the barriers to purchasing microgreens, a ranking method was applied, while consumer perceptions were evaluated using a 5-point Likert scale. The sensory attributes of microgreen varieties were evaluated using a semi-trained panel comprising 20 members. Additionally, the nutritional composition and antioxidant properties were assessed across the three selected varieties. Results: The study surveyed 610 respondents, out of which 65.58% (400 respondents) were familiar with microgreens and hence were included in the study. The majority of participants had a positive perception regarding microgreens, with 84.25% acknowledging potential health benefits. Sensory evaluation of three radish microgreens revealed that all varieties scored well for overall acceptability, indicating positive inclusion potential of microgreens in daily diets. Proximate analysis revealed high moisture, moderate protein and low-fat among the varieties. Calcium, iron, magnesium, copper and zinc were also present. High levels of ascorbic acid, chlorophyll, total phenol and total flavonoids content were found in all the assessed varieties, with purple radish demonstrating the strongest antioxidant activity. Conclusion: Overall, results highlight positive consumer perception, unique sensory profile and high nutritional potential of radish microgreens.
