The nutritional and functional composition of barley varieties' samples were analyzed using AOAC methods. The moisture content of the samples ranged from 7.3% to 12.8%, while the ash content varied from 0.5% to 13%. The crude fiber content ranged from 0.5% to 1.5%, and the crude protein content ranged from 0.73% to 3.4%. Furthermore, the crude fat content ranged from 0.11% to 0.8%. The carbohydrate content of the samples were found to be between 69.5% and 82.5%, with an energy value ranging from 338.2 to 382.02 kcal/100 g. In terms of mineral content, the samples exhibited varying levels of calcium (310-670 mg/100 g), iron (34.9-65 mg/100 g), zinc (8.9-16 mg/100 g), and magnesium (Mg) (520-1122 mg/100 g). In addition, the range of the total phenolic content was 1.2 to 3.1 mg/100 g, while the range of the total flavonoid content was 0.41 to 0.55 mg/100 g. Therefore, barley, a selenium-rich food, acts as an antioxidant, protecting cells from free radical damage, reducing inflammation, and reducing the risk of chronic illnesses. The highest content of stearic acid (3.4 g/100 g) followed by myristic acid (2.6 g/100 g) were found in barley varieties.

Consequently, it is essential to thoroughly examine how various coping mechanisms might affect the relationship between stress and quality of life (QOL). This study aimed to examine the mediation effect of both problem-focused coping (PFC) and emotion-focused coping (EFC) mechanisms on mitigating the effect of stress on the QOL among Jordanian nurses. A multisite cross-sectional descriptive correlational design was used in this study. An online survey was completed by 203 nurses using a convenience sampling technique between October 2023 and January 2024. The study included nurses working in different Jordanian healthcare sectors including governmental, private, and university-affiliated hospitals. Several measures were used to collect data, including questionnaires on sociodemographics, QOL, coping, and stress. Two models were hypothesized for this study. The two models were analyzed using Andrew Hayes Process Macro Model 4 for testing the mediation effects. Additionally, descriptive and correlational analyses were run prior to the main analysis. The results showed that coping significantly mediated the relationship between stress and QOL with variations between PFC and EFC. In conclusion, psychological distress symptoms were common among Jordanian nurses; psychological distress, coping, and QOL are correlating variables. Nurses' stress levels and coping modalities can predict QOL with a superior effect of PFC compared with EFC. Strategies should be put in place to improve effective coping to improve nurses' QOL.

In addition, the perspective of dental care providers who care for patients with SCN and the factors affecting the provision of treatment was also appraised. The Eastern Province of Saudi Arabia served as the site of this cross-sectional study from 1 February 2020 to 31 January 2022. Caregivers of 272 patients with SCN, regardless of age and gender, were recruited in the study. The caregiver's proforma sought information on the demographic characteristics, type of disability, cooperation, medical history, occupation of the parent and patient's behaviour towards oral hygiene and dental healthcare. The second proforma had the dental care provider's perspective about the common disabilities, factors that affect the decision to provide treatment, difficulties patients face in getting their dental treatment and, from the dentist's experience, recommendations to improve the access to dental care for patients with SCN. Statistical analysis was carried out by using SPSS version 22.0. The demographic features, caregiver's perception about oral healthcare accessibility and dental professional's point of view were presented as frequencies and percentages. Chi-square test was applied to compare the proportions. The majority of the caregivers were satisfied with the dental service providers (91.9%) for their patients with SCN. The dental care provider's survey results indicated a shortage of dentists (54.7%) in the region and other factors that pose challenges to special care, like the severity of the disability of patients with SCN (50%), family structure (46.7%), treatment cost (35.6%) and transportation (32.8%). Patients with SCN in Saudi Arabia had a high appraisal of access to dental care and were very satisfied with dental treatment results.

Preference ranking, direct matrix ranking, and informant consensus factor were used for data analysis. A total of 63 medicinal plant species belonging to 59 genera and 41 families were documented.

The mathematical model was developed based on modified classical annular circular plate theory under dynamic loading, and all its formulas were solved using MATLAB 2023. The mathematical model was also verified with real experimental work involving the vibration test of the fabricated composite plate. The composite plate was processed by reinforcing the polyester matrix with E-glass fibers with a 50% volume fraction each by using the handy lay-up method. After fabrication, the composite plate was tested with a universal vibration tester, where the plate was impacted and released to free vibration, and the deflection was measured experimentally to compare it with the theoretical value calculated from the derived model. The plate was tested under two boundary conditions, namely, simply and built-in supported. The findings show good agreement between theoretical and experimental plate deflections at different angles, particularly at built-in supported boundary conditions. Also, a higher natural frequency was recorded at this condition compared to others, and this may be ascribed to the higher shear stresses involved due to large moments at the ends along with supporting.
