Integrating large-scale wind energy in modern power systems necessitates high-efficiency mathematical models to address classical assumptions in power systems. In particular, two main assumptions for wind energy integration in power systems have not been adequately studied. First, nonlinear AC power flow equations have been linearized in most of the literature. Such simplifications can lead to inaccurate power flow calculations and result in technical issues. Second, wind power uncertainties are inevitable and have [...]

Calcareous corneal degeneration is a rare disease characterized by calcium phosphate deposition into the deep corneal layers. Corneal calcification has a multifactorial origin and is associated with various systemic and ocular conditions. Several treatment options showed promising results in the management of this disorder. Herein, two cases of calcareous degeneration occurring postoperatively in patients undergoing surgery for retinal detachment (case #1) and glaucoma (case #2) were reported. Despite normal serum [...]

Non Alcoholic Fatty Liver Disease (NAFDL) is a condition in which an individual suffers from an accumulation of fat in the liver. This is a disease condition with a multifactorial etiology. Some potent causes of such conditions are altered thyroid condition, abnormal metabolism in the body due to aging or menopause, or any other hormonal imbalance. Most of these causes are regulated by genetics, lifestyle, and environmental factors. Menopause comes with tremendous hormonal turmoil in the human body and brings vario [...]

In this study, we prepared a fine-grained, aluminum-reinforced alumina support matrix of the active mass of catalysts, which showed activity in heterogeneous catalytic reactions stimulated by electromagnetic radiation in the microwave range. The support absorbed microwave radiation of 2.45 GHz. We compared the textural characteristics of samples of Al/Al2O3 supports obtained by conventional heat treatment to those synthesized by heat treatment in a microwave field. We found several advantages of heat treating poten [...]

In this study, by producing bifunctional material, hydrolysis, and supercapacitor applications were investigated. The carbon nanotube-supported Pt catalyst was prepared using the sodium borohydride (NaBH4) reduction. Surface characterization of the synthesized Pt/CNT catalyst was performed using scanning electron microscopy-energy dıstrıbutıon X-ray spectrometer (SEM-EDX), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Hydrolysis experiments were performed after deciding on the appropriate ato [...]

This paper reviews the growing importance of satellite imagery to provide Normalized Difference Vegetative Index (NDVI) maps, relevant to environmental land management assessment, in the context of resource and climate-related conflict based upon our own humanitarian project-related support. Near real-time space-based monitoring benefits land assessment, human rights observers, and Non-Governmental Organizations (NGOs), in the presence of unstable regimes or socio-economic upheaval. Access to areas to validate clai [...]

Carnauba straw (Copernicia prunifera), residual biomass derived from wax extraction, was evaluated as a potential feedstock for bioenergy production. The characterization was carried out using elemental analysis, proximate analysis, Higher Heating Value (HHV), FTIR spectroscopy, SEM, and FRX. The carbonization, using a Muffle Furnace, was applied as a thermal conversion technique to improve the fixed carbon content, and preliminary densification was done to assess the potential for future production of briquettes.

The present research was part of a cross-sectional project involving children aged 8 to 10 years in Porto, Portugal. The project involved a first research part at primary schools where the health tests and a questionnaire were performed and a second research part concerning environmental conditions. Two groups emerged from the health questionnaire answers: one group that reported “asthma diagnosed by a doctor” and/or “wheezing or whistling in the chest during last 12 months” and another that answered negatively to [...]

Water scarcity is one of the most pressing global challenges, particularly in arid and semi-arid regions. In this context, the Gaza Strip, where groundwater is the only available natural water resource, faces severe water stress due to overexploitation and drought conditions. This study aimed to review the recent water budget for the Gaza Strip by collecting data for the years (2021-2022) which was analyzed, discussed, and compared with other studies. The results showed a sharp deterioration in the Gaza Strip in te [...]

According to 2019 WHO data, neurological conditions contribute to 1503.39 disability-adjusted life years (DALYs) per 100,000 population. Approximately 57% of office-based physicians use EHR systems and the natural place to incorporate standardized ePRO is into EHR. However, implementing patient-reported outcomes (PROs) for neurological conditions is challenging because many patients are elderly, have comorbidities, and experience cognitive impairment. As healthcare digitization increases, we propose a framework for [...]
