This paper examines how digital governance systems enable public administration organisations in Thailand and Indonesia to enhance the effectiveness of their management of migrant populations. It employed qualitative methods, including document assessment and interviews with public administration personnel and migrant community representatives, to conduct a comparative study between Thailand and Indonesia. It evaluates digital governance systems, their associated policies, and execution methods for migrant service delivery. It shows that Thailand uses digital governance to enhance migrant service delivery through comprehensive system integration, real-time data management, and stakeholder participation. The research reveals that Indonesia faces two primary obstacles, stemming from inadequate infrastructure and inconsistent policies. In addition, the research provides essential knowledge about digital governance in public administration, demonstrates its value in addressing the complexities of migration management, and offers guidance to policymakers facing similar challenges.

Background: Oral tumors comprise a wide spectrum of lesions with variable biological behavior and represent a significant health concern worldwide. In Libya, epidemiological and clinicopathological data on oral tumors remain scarce and fragmented. Methods: A retrospective observational study was conducted using medical and histopathological records of 152 patients diagnosed with oral tumors between April 2024 and December 2025. Data on age, sex, anatomical site, histopathological diagnosis, tumor nature (benign or malignant), and treatment modalities were collected and analyzed descriptively. Results: The mean age of patients was 46.3 ± 15.8 years, with a male predominance (61.8%) and a male-to-female ratio of 1.6:1. The most affected age group was 41–60 years. The tongue was the most common anatomical site (34.2%), followed by the gingiva and buccal mucosa. Malignant tumors accounted for 64.5% of cases, with oral squamous cell carcinoma being the predominant histopathological type. Benign tumors constituted 35.5% of cases and were mainly odontogenic, particularly ameloblastoma and odontoma. Surgical treatment was the primary management approach, with adjuvant therapy applied in selected malignant cases. Conclusion: Malignant oral tumors, particularly oral squamous cell carcinoma, were predominant among middle-aged male patients, with the tongue as the most frequently involved site. These findings highlight the importance of early diagnosis, histopathological confirmation, and timely surgical intervention, and emphasize the need for improved awareness and preventive strategies to reduce the burden of oral tumors in Libya.

In order to develop a sustainable and reliable hybrid energy generation system model in Southern Libya using concentrated solar power (CSP) with thermal energy storage (TES) to improve the overall efficiency, flexibility and sustainability of the energy generation facilities located in this area, this study has developed an energy generation system that integrates CSP using molten salts as TES with a gas turbine based on the equilibrium conditions defined by the use of sodium nitrate-potassium nitrate (NaNO3-KNO3); essentially, a two-tank molten salt system that can store heat at temperatures up to 565 degrees Celsius. The heat is then captured and produces electricity during non-solar times thereby allowing power generation to continue on demand and ensure continuity of electrical service. The researchers will utilize the System Advisor Model (SAM) to simulate performance of the solar field and the TES, while the Engineering Equation Solver (EES) will be used to conduct a thermal analysis of the thermodynamic processes associated with the Brayton gas turbine cycle. The researchers found that the addition of molten salt TES to a CSP energy system increased thermal efficiency by approximately 22 percent compared to a standard fossil fuel generation system, reduced fuel consumption by 26 percent and reduced carbon dioxide emissions by 18 percent versus a similar thermal generation system. Additionally, when the levelized cost of electricity (LCOE) from the integrated CSP, molten salt TES and gas turbine system was compared with that of traditional fossil fuel generation systems the total LCOE decreased from $0.22/kWh to $0.16/kWh indicating that this hybrid energy generation system provides an economically viable alternative for use in regions that are primarily arid and/or remote such as Ubari in Southern Libya, while addressing both fuel supply and grid stability challenges Keywords: CSP, TES, molten salt storage, Brayton cycle, hybrid energy system, LCOE, CO2, solar thermal.

Abstract Rhesus D alloimmunization remains a preventable cause of fetal anemia and perinatal morbidity, yet anti-D immunoglobulin prophylaxis continues to face limitations related to availability, cold-chain logistics, and incomplete protection. This systematic review examined whether intravenous immunoglobulin (IVIG) can functionally replace anti-D prophylaxis and explored its translational mechanisms across maternal–fetal contexts. Comprehensive searches of PubMed, Scopus, and Embase identified 1,277 records. Following PRISMA-guided screening and eligibility assessment, 38 studies were included, encompassing randomized trials, cohort and case-control studies, meta-analyses, and mechanistic reports. Evidence synthesis demonstrated that IVIG administration was associated with reduced maternal antibody titers, delayed need for intrauterine transfusion, lower exchange-transfusion rates, and improved neonatal survival, without increased adverse effects. Mechanistic data indicated that IVIG may exert immune modulation through Fc-receptor blockade, B-cell down-regulation, and FcRn saturation, mirroring the immunologic tolerance induced by anti-D. Emerging evidence integrating cfDNA-based fetal RhD genotyping further refines patient selection, minimizing unnecessary prophylaxis. Despite heterogeneity in study design and dosing, pooled outcomes supported a protective effect of IVIG comparable to or exceeding conventional anti-D in high-risk pregnancies. The evidence map highlights current gaps in large randomized prophylactic trials and underscores the translational potential of IVIG as a globally accessible immune-tolerant strategy. These findings call for next-generation clinical programs to redefine alloimmunization prevention, integrating molecular diagnostics, personalized immune monitoring, and sustainable biologic replacement of anti-D prophylaxis.

Health and beauty are essential aspects of a Muslimah’s life, which Islamic values should maintain as a form of gratitude and responsibility for the body entrusted by Allah. However, a lack of education regarding proper, healthy, and halal self-care practices remains an issue. This community service program aims to enhance Muslim women's understanding of healthy and Islamic-compliant skincare through a seminar and beauty class themed "Care about Beauty, Care about Health". The activities consisted of an educational seminar on skincare awareness and a hands-on beauty class using halal-certified products. The implementation methods included lectures, demonstrations, interactive Q&A sessions, and evaluation via questionnaires. The program involved both academics and halal beauty practitioners from Wardah. The results showed a significant increase in participants' knowledge of skincare techniques and awareness in selecting safe, halal beauty products. Program outputs included an educational self-care module, an article publication, and visual documentation, serving as a reference and evaluation material for future programs. This initiative is expected to have a lasting impact on raising awareness among Muslim women about the importance of maintaining a balanced approach to personal care, one that combines physical wellness with spiritual integrity.

The global energy crisis caused by the limits of oil reserves urges the need for alternative energy solutions, including pyrolysis-based oil energy. In this study, we investigate the pyrolysis of corn cob biomass with varying particle sizes (3 mesh, 5 mesh, 7 mesh, and 10 mesh) to evaluate its effect on product yields and physical properties. Each experiment was conducted for 90 minutes using 300 grams of feedstock, which had been pre-dried in a microwave oven at 120°C for 2 hours. The results revealed that the bio-oil yield decreased with smaller particle sizes, from 31.52% at 3 mesh to 26.12% at 10 mesh. Conversely, bio-char yield increased from 37.48% to 46.47%, while bio-gas yield decreased from 31.00% to 27.42%. This suggests that excessively small particle sizes reduce bio-oil yield due to uncontrolled reactions despite their higher surface area. The bio-oil density ranged between 1.0235 and 1.0353 g/ml, indicating consistent physical properties across particle sizes. The inlet and outlet temperatures of the reactor (T1 and T2) and condenser (T3 and T4) remained relatively stable, indicating consistent condensation of pyrolysis gases into liquid bio-oil. This study has successfully provided insight into the optimization of a particle size of the waste processing of corn cob into energy by using the pyrolysis method
