In the present study, a eco-friendly, low cost and biocompatible route to synthesize the NiNPs, has been proposed using the Pyrus calleryana (Callery pear) leaves extract, which is comprised of polyphenols, flavonoids and reducing sugar, which act as an excellent reducing and stabilizing agent. The as prepared NiNPs were characterized by various methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIF), atomic force microscopy (AFM), and UV-Vis spectroscopy. XRD proved crystalline tetragonal structure of NiNPs and SEM and AFM showed the homogeneous distribution of nanoparticles with particlesized ranging between 18.75 - 32.43 nm. Functional groups (hydroxyl, carbonyl and aromatic rings) essential in nanoparticle stabilization were characterized with FTIR, whereas UV-Vis, evidenced an absorption peak at ∼380 nm, corresponding to NiNP formation. The phytochemical composition of the P. calleryana extract was an important factor for nanoparticle synthesis as polyphenols and flavonoids served to nucleate and prevent aggregation. This research featured the potential of plant-assisted synthesis as a green approach for nano-synthesis and provided structural and functional attributes of bio-mediated NiNPs for environmental and industrial applications.

Involuntary hospitalization for the treatment of patients with psychiatric disorders is a necessity in modern scientific psychiatric practice. Hospitalization, in general, of the mentally ill is an important and complex issue. The purpose of this study is to investigate the attitudes and perceptions of nurses working in the psychiatric field regarding involuntary hospitalization. In order to achieve this, a questionnaire on "Attitudes and perceptions of nursing staff working in psychiatric clinics and psychosocial rehabilitation structures regarding involuntary hospitalization" was created as a research tool. Results were analyzed with the IBM Statistical Package for Social Sciences (SPSS), version 25.0. The results showed that the opinions of the respondents are consistent with those resulting from surveys, both in Greece and abroad. The majority agree with the process of involuntary hospitalization, while staff in psychiatric units are knowledgeable about the legislation governing this type of hospitalization. In conclusion, it is necessary to investigate the legal framework that governs involuntary hospitalization in Greece, as well as the conditions that prevail in the hospitals that accept such cases.

To investigate the nature of job commitment among Human Resource Manager according to job experience, and type of job. A cross-sectional survey design was employed with a purposive sample of 100 managers. Job commitment were measured using the Organizational Commitment Scale (Mooday, Steer & Porter, 1979). The results of one-way ANOVA tests revealed significant differences in job commitment scores by human resource manages job type and job experience. However, significant job commitment were found based on job type ((F = 66.587; P < .01)), and job experience (F = 3.914; P < .01). Regression analysis further indicated that human resource manager’s job type and job experience were modest but significant predictors, explaining 39.5% (R² = .395, p = .001), and 14.2% (R² = .142, p = .001) of the variance in job commitment scores, respectively. Organizational commitment in human resource management was the main focus of this study. Despite the fact that this idea has been extensively researched in many academic settings, no study has been conducted in Bangladeshi private institutions as of yet.

This paper examines the overall quality of healthcare in Saudi Arabia and then explores the relationship between the health insurance (public and private) and the overall quality of health care. By reviewing publications such as journals, books, internet articles, presentations, dissertation, online sources and the fourth, this research is conducted by literature review methodology. We are interested in the following research questions: 1) What is the influence of health insurance on gaining access to quality health care services? 2) How can health insurance help in enhancing patient satisfaction and reducing financial distress and medical debts? And 3) What is the role of health care insurance in providing opportunities for timely medical interventions and reducing the cost of medical care? This study discovers that there has been an improvement in the quality of health care services in the Kingdom of Saudi Arabia because of the private and public health insurance policies. It can be concluded from the study that Saudi Arabia has come far enough in providing the health care insurance to its pilgrims and also the employees from the foreign countries but there is always a place to make changes and introduce policies that can help everyone irrespective of the regional differences, socio-economic differences or religious differences, and everyone can get the best quality of health care. We propose an integrated theory of factors impacting on the quality of healthcare in the context of Saudi Arabia.

This paper uses the Differential Evolution (DE) algorithm to optimize essential antenna parameters for maximum communication system performance. The research concentrated on improving antenna performance through performance indicator enhancement, including energy concentration and gain, while optimizing return loss, beamwidth, and efficiency to support reliable distant communications, especially under difficult operating conditions. The optimized parameters of the VHF air-to-ground antenna system reached 76.73 MHz frequency along with 45.00 dB gain, 10.00 degrees beamwidth and 0.92 efficiency, which demonstrates broad operational coverage while preserving low power dissipation. The impedance matching is effective because a return loss measurement shows 5.00 dB. The investigation applied the optimization structure to optimize a 5G millimetre-wave (mmWave) antenna system for dealing with propagation issues caused by high frequencies. The system achieved optimized parameters at 33.00 GHz frequency with 29.61 dB gain and 5.00 degrees beamwidth while maintaining 0.98 efficiency, proving its ability to handle dense deployments through minimal interference mechanisms and maximum spatial utilization capacity. The antenna's high return loss value of 28.14 dB demonstrates the signal integrity performance. A DE algorithm optimization succeeded with a validity cost of 1.173050, which confirmed its precision in calculations and demonstrated a steady MAE reduction, which proved the algorithm had reached its correct solution path. Findings from the research show that the DE algorithm optimizes antenna design problems in VHF frequencies and future 5G systems with both efficiency and robustness. The developed research findings deliver practical and methodological contributions to antenna optimization, enhancing energy efficiency and system performance for upcoming wireless communication networks.

This study examines the effect of Low-Density Polyethylene (LDPE) modification on the brittleness and stiffness of bituminous concrete mixtures and develops a regression model to predict the brittleness ratio (SR). Experimental results reveal that adding LDPE significantly increases stiffness, with brittleness ratios ranging from 1.998 to 3.169. While higher stiffness improves resistance to permanent deformation and rutting, brittleness ratios above the critical limit of 3.0 indicate a risk of premature cracking, especially at low temperatures. This highlights the need to optimize LDPE content to balance stiffness and ductility. A regression model was created to predict brittleness based on proportions of granite (Z₁), sand (Z₂), bitumen (Z₃), and LDPE (Z₄). The model showed good statistical validity, with an F-calculated value of 1.382 (below the critical 2.48 at 5% significance) and an R² of 70.38%, explaining a significant portion of brittleness variability. The Mean Absolute Percentage Deviation of 7.2% between predicted and experimental values confirms its accuracy within acceptable engineering limits. These findings suggest that LDPE-modified bituminous concrete offers improved mechanical performance but requires careful LDPE dosage control to avoid excessive brittleness. The validated model serves as a practical tool for designing durable, sustainable asphalt pavements balancing stiffness and flexibility across diverse environments.

The Blind Assassin, is the masterpiece by Canadian author Margaret Atwood, whose complex structure, various themes and identity concerns have always been the focus of controversy among literary critics. However, few of them explore the otherization of male and female characters’ collective identities in the novel through narrative focalization. Thus, based on some theories relevant to identity concerns and feminist narratology, the paper tries to investigates how camera focalization simulating objective observation——constructs and others the collective identities of both sexes through embedded news clippings. The analysis reveals that female collective identity is othered through patriarchal mechanisms and the reduction of women to decorative objects under the gaze. Meanwhile, male collective identity undergoes otherization through intra-group power struggles. Thus, the paper exposes the co-domination and the co-shaping of both sexes by masculinity and patriarchal culture, and Atwood’s advocation of decentralized gender view and harmonious relationship between the two sexes, providing a reference for the relevant studies on identity politics and narrative forms.

This paper addresses the concept of sustainable urban design by examining three prominent theories: New Urbanism, Compact City, and Green Urbanism. It analyzes the application of these theories through three significant urban projects: Celebration, Florida (New Urbanism), Hammarby Sjöstad (Compact City), and Atlanta BeltLine (Green Urbanism), based on six core principles of sustainable urban design, including mixed-use integration, sustainable mobility, social equity, environmental efficiency, quality of life, and urban resilience. The analysis reveals that the application of these principles faces considerable challenges. For instance, Celebration demonstrates success in improving public spaces and supporting sustainable mobility but fails to address social equity and environmental responsiveness. Hammarby Sjöstad, on the other hand, integrates urban density with sustainable systems, but economic challenges remain in fully implementing environmental solutions. Atlanta BeltLine offers a strong example of how green urbanism can repurpose old infrastructure into green networks, although social challenges, such as real estate inflation, threaten its social equity goals. The paper concludes with a discussion on the gap between theory and practice, highlighting how social and economic factors play a significant role in limiting the realization of sustainable urban design goals. Finally, it emphasizes the need for collaboration between urban planners, designers, policymakers, and local communities to develop flexible design solutions that balance environmental, social, and economic considerations. This research underscores the complexity of sustainable urban design, emphasizing the importance of adapting theories to real-world challenges in order to create cities that are resilient, inclusive, and sustainable for future generations.

This work is set out to make an appraisal of the contributions of World Trade Organization (WTO) towards enhancing trade in developing countries. Many developing countries have joined the WTO in order to protect themselves against the unfair market practices common in international trade. Developing countries represent the majority members of the institution and participate actively in the WTO trading system. The WTO has provided in its agreements, some Special and Differential (S&D) treatment to developing countries. It is rather a paradox that most of these provisions to a greater extent have not been effective towards enhancing trade in developing countries. The objective of this work is to examine the extent to which the WTO has contributed towards enhancing trade in developing-member countries. The method adopted in this research is doctrinal wherein, both primary and secondary sources of data were collected. The findings reveal among others that, the S&D treatment provisions accorded to developing countries who are vulnerable members of the institution have not been effectively implemented. The WTO lacks an efficient mechanism to ensure the effective implementation of its rules. It is therefore recommended that, the WTO should put in place an effective mechanism to ensure that developed member countries comply with the S&D treatment accorded to developing countries. The organization should equally provide more assistance (tariffs reduction) to developing countries to enable them achieve their economic growth and development. Developing countries on the other hand should establish transparent domestic trade policies necessary to implement the WTO rules.

Background: The term toxoplasmosis is reserved to describe the clinical or pathological disease caused by Toxoplasma gondii and T. gondii infection for an asymptomatic primary infection or persistence of the parasite in tissues (chronic or latent infection). Objective: To evaluate the significance of detecting Toxoplasma gondii antigens in diagnosing and predicting the prognosis of acute toxoplasmosis, assessing its potential role in early intervention and treatment monitoring. Materials and Methods: The samples of the present study consisted of 39 women,31 of them infected with toxoplasmosis and 6 of them did not have toxoplasmosis, their age range was between (17-41) years, the blood samples were collected from Central Public health Laboratories (CPHL) in the period from (May 2022 to November 2022). Human Toxoplasma gondii ELISA kit is for the qualitative determination of Toxo-gondii in human serum. Results: The results of the present study showed in Table (1) since there were 26(96.3%) of housewife women had IgG Abs of T.gondii, while there was 1(3.7%) of employment women had IgG Abs of T.gondii , there were a significant differences between job categories and antibodies (IgG Abs) of T.gondii P=0.32. Conclusions: IgG Abs and IgM Abs of T.gondii presents more in housewife women than employment women. The Ag of T.gondii present in aborted women more than in non-aborted women. The Ag of T.gondii present more in women who had IgG Abs of T.gondii more than in women who had IgM Abs of T.gondii.

Introduction: Hypertension is a leading global health issue, especially in low-income countries, and is strongly associated with dyslipidemia, a key risk factor for cardiovascular disease. Despite known associations, the specific relationship between lipid profiles and hypertension remains inadequately explored in local populations. This study aimed to assess the association between lipid profile components and hypertension among adults. Methods: A cross-sectional study was conducted on 100 participants (50 hypertensive and 50 normotensive individuals) at Sirat e Mustaqeem health care center, Karachi, from October to December 2024. Patients aged 30–60 years, with no prior antihypertensive treatment or chronic comorbidities, were enrolled using purposive sampling. Blood pressure was measured using standard procedures. Fasting venous blood samples were collected for lipid profile analysis, including total cholesterol (TC), triglycerides (TG), LDL-C, and HDL-C. Statistical analysis was performed using SPSS v21, with significance set at p < 0.05. Results: The study population included 65% males and 35% females. Most hypertensive patients exhibited elevated levels of TC, LDL-C, and TG, while HDL-C levels were comparable between groups. ANOVA analysis showed a significant association of cholesterol with BMI (F = 25, p < 0.05) and LDL levels (F = 20, p < 0.05). However, no within-group variability was observed, suggesting potential data homogeneity or recording issues. Conclusion: The findings suggest a significant association between dyslipidemia—particularly elevated TC, LDL-C, and TG—and hypertension. Routine monitoring of lipid profiles in hypertensive patients is recommended to reduce the risk of cardiovascular complications.

Early prediction of nurses’ turnover and turnover intention is essential to enhancing staff retention, ensuring job satisfaction, and maintaining the quality of patient care. This systematic review evaluated studies that used machine learning techniques to predict either actual nurse turnover or turnover intention, with the goal of identifying key predictive variables and assessing model performance. A comprehensive search was conducted across PubMed, CINAHL, Cochrane Library, PsycINFO, and Google Scholar, following PRISMA guidelines. Out of 596 records screened, eight studies met the inclusion criteria. These studies were appraised using the CASP Clinical Prediction Rule Checklist. The most frequently reported predictors were salary and age. While several models, such as Decision Tree and Random Forest, demonstrated high internal predictive accuracy, external validation was lacking across all studies, limiting generalizability. Future research should focus on validating models in diverse populations and healthcare settings and on improving standardization in outcome measures and reporting practices to enhance the applicability of predictive models in nursing workforce planning.

Introduction: Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease of unknown etiology that can lead to cirrhosis and liver failure if left untreated. Environmental triggers, particularly viral infections, have been implicated in disease onset. Case Presentation: We report the case of a 24-year-old woman who presented with abdominal pain, nausea, and cholestatic jaundice. Initial serological workup revealed acute hepatitis A (HAV) infection. Despite conservative management, liver function continued to deteriorate. Autoimmune screening showed high-titer antinuclear antibodies (ANA), and liver biopsy revealed interface hepatitis with portal lymphoplasmacytic infiltrates and fibrosis (A3F1), consistent with AIH. Conclusion: This case highlights the potential role of HAV infection as a trigger for autoimmune hepatitis. In cases of persistent liver dysfunction after acute viral hepatitis, clinicians should maintain a high index of suspicion for evolving autoimmune liver disease.
