This present study aims to investigate 55 herbal products indicated for men’s sexual health from the Malaysian market for adulteration of PDE-5 inhibitors and analogues. The screening and identification of 20 PDE-5 inhibitors and analogues in herbal products of various forms (powder, capsules, tablets, and pastels) were conducted using gas chromatography–electron impact-mass spectrometer (GC-EI-MS). The analysis has shown that 19 herbal products were adulterated with PDE-5 inhibitors and analogues. Unique ion fragmentations and the presence of molecular

The current research aims to determine the requirements of Trends of International Mathematics and Science Study (TIMSS 2019) and to find out the extent to which the content of science textbooks for grades (1-4) in the Sultanate of Oman includes the requirements of (TIMSS 2019). Only the Cognitive Process dimension has been considered when conducting the analysis. The study population includes all science books from the first to the fourth grade for the academic year 2021-2022. The study identified and organized the requirements in the study tool, which is a list of requirements of (TIMSS 2019). After confirming its validity and reliability, the analysis was performed, and data were collected and analyzed statistically using frequencies

Results: The results summarized two goals, the first goal stipulates (to identify the degree of cyberbullying among academically outstanding students in the middle school stage). To achieve this goal, the researchers applied the research tool (electronic bullying scale) and then extracted the arithmetic mean for the sample of the current research, which amounted to (6.28) with a standard deviation of (4.03). Then the researchers applied the t-test for one sample to identify the significance of the differences between the means. The arithmetic mean for the sample and the hypothetical (theoretical) mean, which amounted to (11.5) degrees, and after applying the T-test for one sample, it was found that the calculated T-value, which amounted to

Aimed at the researcher during his research to characterize the elements of internal control under the standards of the state and measurement and analysis of the extent to which those elements in the form of technical education through a selected sample included the three institutes (Institute of Directors Technical Institute for the preparation of the trainees and the Institute of Technology). The researcher used the method of analysis the descriptive terms used questionnaire to collect the necessary information and were subject to analysis using descriptive statistical methods Kalost mean and standard deviation, and research found a set of conclusions, including a commitment to the elements of internal control in the form of technical

Pectin is available in many plants and in this study, the peels of tomatoes and beet were used to be an economical source of pectin production instead of dumping it with waste or using it as animal feed. The pectin extracted from the peels using different solutions, namely citric acid (2 M), oxalic acid (2%) and hydrochloric acid (0.5 M) the outcome of the extraction methods, 7. 1%, 6% and 11% respectively for tomatoes peels, while the pectin of beet peels were 8%, 6.5%, and 8.3%, and the highest percentage obtained in the manner of hydrochloric acid adopted in the manufacture of yogurt.Yogurt was manufactured with four treatments, in the first treatment standard pectin was added and the second treatment in addition to the pectin extracted
