Title: Effect of RRA Heat Treatment Parameters on Mechanical Properties Of 7075 High Strength Aluminum Alloy Authors: Al-Nifawi, Muhammed; Dhahya, Fouad Abstract: Retrogression and Re-Aging Heat Treatment improves tensile and wear resistance of aluminum alloys, to study the effect of Retrogression temperature and Retrogression time on the tensile strength, Toughness Impact and Hardness of 7075 aluminum alloy, we have applied in this research Retrogression treatments at different temperatures are 150°C, 180°C, 240°C and 370°C for 15 min, 30 min and 90 min. When the retrogression temperature was 180°C for 30 min, the alloy has reached its highest tensile strength and hardness it was respectively 586 Mpa and 165 HB, While the alloy has reached its highest impact toughness it was 32.7 J\Cm2, When the retrogression temperature was 370°C for 30 min.

The re-searcher used the analytical descriptive method because of its suitability for the purposes of the study. The sample of the study was chosen in the cluster method from 27 schools with 879 students. The researcher prepared a questionnaire consisting of (30) verifiable items. Statistical packages (SPSS) were used for data processing through the use of the following statistical processors: Percentages and arithmetic averages, single-variance analysis, alpha-Cronbach correlation coefficient, the study found the following important results: There were statistically significant differences in the use of the elementary students of the social networking sites due to the sex variables and the grade for the benefit of males and the eighth grade, respectively. There were also no differences according to the variables: place of residence, level of the father's education, level of mother's education, and access to social networking sites. The study recommended that experimental studies should be carried out in order to provide awareness programs for students to fill their leisure time and guide them in the and safe way to use social net-working sites.

Title: Valuating the Reality of Using E-Learning System (Moodle) in University Learning under the Pandemic of Covid 19 Among Physical Education Students (PES) At West Bank Universities-Palestine Authors: Salameh, Hamed; Qadoume, Ali; AbuAlia, Motasem; Qadoumi, Mohamed Abstract: The study aimed to identify the degree of benefit and difficulty in using e-learning system (Moodle) in university learning Under the pandemic of Covid 19 among PES at West Bank universities-Palestine, in addition to determining the differences according to variables of gender, study level & university. The researchers used descriptive& analytic approach. The study was conducted on a random sample of (103) students Which represents a percentage of (17.13) from PTUK &An-Najah National University. In order to collect data, the researchers prepared two scales are They are (degree of benefit, degree of difficulty) from students' use of the educational Moodle system. The results of the study revealed the following: -The degree of benefit from using e-learning system (Moodle) in university learning Under the pandemic of Covid 19 among study sample were low. -The degree of difficulty from using e-learning system (Moodle) in university learning Under the pandemic of Covid 19 among study sample were middle. -There weren't statistically significant differences in benefit & difficulty from using e-learning system (Moodle) in university learning Under the pandemic of Covid 19 among study sample according to variables of gender, study level& university. The researchers recommend the need to Hold training courses on the use of the various e-learning systems in Palestinian universities for students and academic staff.
