The purpose of the present study is to investigate the effect of explicit affective strategy instruction on the speaking performance of Freshmen English majors at Faculty of Education, Suez University, Egypt. The design of the study is a pre-post quasi experimental one. The instrument is a pre/post speaking performance test (designed by the researcher). Participants were eighty Freshmen English majors, randomly divided into two groups: a control group (N=40) and an experimental one (N=40). During the experiment, the experimental group was explicitly taught some affective strategies (lowering anxiety, encouraging yourself and monitoring emotions) while the control group was taught using the traditional method. All participants were tested using the pre/post speaking performance test before and after the intervention. The difference between the post test&rsquo;s mean scores of the control and experimental groups were calculated using Independent Samples t-test and the difference in the mean scores between the pre- and post tests of speaking performance was calculated for each group separately using Paired Samples t-test. A significant difference was found between the post test&rsquo;s mean scores of the control and the experimental groups in favor of the experimental group. Moreover, a significant difference was found between the mean scores of the pre and post test of the experimental group in favor of the post test. It was concluded that participants&rsquo; level of speaking performance significantly improved after receiving the explicit affective strategy instruction.

Abstract Dam construction is one of the most popular solutions for managing water resources. In recent years, changes in patterns of regional seismicity associated with large impoundment dams have raised concerns among environmentalists. In this study, five large dams located in Iran were studied from this perspective. The Gutenberg-Richter, linear regression and T-test were used to examine the seismic changes in the radius of 100 km of each of the dams during a twenty-five-year period before and after the construction of the dams. The results revealed that the seismicity level and relative density of large and small earthquakes in three of these dams have increased after dam construction. A significant difference between the magnitude of earthquakes, as well as the number of earthquakes before and after the construction of dams in the region, was recognized. However, the results of the T-test statistical analysis indicated that the mean depth of the earthquakes and their distance from the dams before and after construction have not changed significantly. Overall, these results indicated that the construction of large impoundment dams has been associated with some changes in patterns of regional seismicity. The findings would guide researchers to further investigate the type of impacts that dam construction may have on seismicity patterns.

PURPOSE: The biodistribution of sodium pertechnetate, the most used radiopharmaceutical in nuclear medicine, has not been studied in details after bariatric surgery. The objective was to investigate the effect of Roux-en-Y gastric bypass (RYGB) on biodistribution of sodium pertechnetate (Na99mTc-) in organs and tissues of rats. METHODS: Twelve rats were randomly divided into two groups of 6 animals each. The RYGB group rats were submitted to the Roux-en-Y gastric bypass and the control group rats were not operated. After 15 days, all rats were injected with 0.1mL of Na99mTc- via orbital plexus with average radioactivity of 0.66 MBq. After 30 minutes, liver, stomach, thyroid, heart, lung, kidney and femur samples were harvested, weighed and percentage of radioactivity per gram (%ATI/g) of each organ was determined by gama counter Wizard Perkin-Elmer. We applied the Student t test for statistical analysis, considering p<0.05 as significant. RESULTS: Significant reduction in mean %ATI/g was observed in the liver, stomach and femur in the RYGB group animals, compared with the control group rats (p<0.05). In other organs no significant difference in %ATI/g was observed between the two groups. CONCLUSION: This work contributes to the knowledge that the bariatric surgery RYGB modifies the pattern of biodistribution of Na99mTc-.
