Due to its high ability to absorb ultraviolet rays in a wide spectrum, zinc oxide has emerged as the most important element used in the manufacture of sunscreens and cosmetics. This study aimed to determine the composition of zinc oxide nanorods and nanoparticles, as well as their impact on UV ray absorption. This was done by using Field Emission Scanning Electron Microscopy (FESEM-EDS) and Ultra Violet (UV-Visible) spectroscopy to look at sunscreen samples that had different amounts of zinc oxide added to them. We prepared two types of commercial zinc oxide powder using a chemical bath deposition method. After characterizing samples of the two powders using FESEM-EDS spectroscopy, various shapes emerged, with rods dominating in both powders. The length of the structure was 224.7 nm, 9.443 ?m, and the diameter was 75.65 nm, 859.9 nm, respectively. The sun protection factor and the critical wavelength for the prepared samples were calculated using UV-Visible spectroscopy to measure the absorbance. An increasing zinc oxide to a certain extent led to an increase in UV ray absorption in all regions of the UV ray wavelength, with the ideal zinc oxide ratio being. The sunscreen had a concentration of 27.5%, and the use of zinc oxide provided broad protection from ultraviolet rays in all samples at the critical wavelength. In conclusion, increasing zinc oxide concentration in sunscreen increased the sun protection factor, critical wavelength, and UV ray protection.

Patient: Female, 38-year-oldFinal Diagnosis: Parasitic acute cholecystitusSymptoms: Abdominal painClinical Procedure: —Specialty: SurgeryObjective: Rare diseaseBackgroundClonorchis sinensis is a common liver fluke that typically inhabits the bile ducts, with infections primarily reported in endemic regions such as Northeast China, Korea, Taiwan, and Vietnam. Diagnosing parasitic infections of the biliary system can be challenging, particularly because their clinical presentation often overlaps with that of more common conditions such as acute or chronic cholecystitis. In regions where such parasites are not endemic, these infections are often overlooked, potentially leading to delayed or inappropriate treatment. Increased awareness is therefore essential.Case ReportWe present a case of a 38-year-old woman from Irbid, Jordan, with no prior medical or surgical history, who presented with symptoms consistent with acute cholecystitis. Imaging showed a distended gallbladder with pericholecystic fluid, and laparoscopic cholecystectomy was performed. Histopathological examination revealed features of acute-on-top-of-chronic cholecystitis with a mixed inflammatory infiltrate including eosinophils. A fluke-shaped parasite, measuring approximately 2×1 millimeters in size and containing eggs, was morphologically consistent with Clonorchis sinensis. This finding was unexpected given the patient’s lack of travel to endemic areas or known dietary exposure risks, such as consumption of raw freshwater fish. She was treated successfully with anti-helminthic medication and recovered completely without complications. Post-treatment follow-up confirmed full resolution without recurrence.ConclusionsAlthough Clonorchis sinensis is not native to Jordan, this case highlights the importance of considering parasitic infections in the differential diagnosis of cholecystitis, even in atypical settings. As global travel and food importation increase, healthcare providers must remain vigilant for uncommon infectious etiologies presenting in non-endemic areas.

ABSTRACT The applicative significance of electroactive microswimmers is pivotal in the field of biotechnology. Using an undulating sheet model, this article presents the biomechanics of electrically regulated spermatozoa motility. This complex wavy sheet, which is self-propelling in the negative axial direction, is enclosed by two stiff walls. The fluid surrounding the spermatozoa is thought to be an electroosmotic Jeffrey fluid. Momentum equations are reduced as a consequence of using the lubrication approximation. To find the exact solution, the resulting ODE is solved by using integration. The numerical root-finding approach refines the unknowns that are contained in the boundary conditions. Graphs are used to display power losses, cell speed, flow rate, fluid velocity, and streamline patterns. Exposure to an electric field can enhance or reduce cell activity effectively.

Abstract Marine ecosystems, particularly in the Gulf of Aqaba, face growing threats from anthropogenic activities and industrial pollution, necessitating advanced monitoring for sustainable management. This study presents a real-time remote monitoring (RTRM) system that integrates wireless sensor networks and machine learning (ML) to enhance water quality assessment. By continuously capturing key parameters, dissolved oxygen (DO), pH, conductivity, turbidity, and sediment concentration, the system enables dynamic tracking of ecological health. Biosensors and physicochemical sensors were combined with geographic information system-based spatial analysis. At the same time, random forest and artificial neural network models were trained on 6 months of data and validated through 10-fold cross-validation, DO: RMSE = 0.45 mg/L, R 2 = 0.92. The RTRM system provided automated analytics and early warnings for environmental risks, including coral bleaching and pollutant spills. Results showed that DO levels generally supported aquatic life, though northern coastal areas were more vulnerable due to localized pollution. Turbidity and sediment patterns highlighted recreational disturbances, particularly from boating. Compared to traditional methods, the RTRM system improved predictive accuracy by 20% and reduced monitoring costs by 30%. By unifying in situ sensing, remote sensing, and ML-based forecasting, this framework offers a scalable, cost-effective tool for real-time marine ecosystem management in the Red Sea and comparable regions.
