The current search aims to identify First: To measure the level of authoritarian personality among the students of the sample as a whole. Second: Measurement of differences in the level of authoritarian personality among students in the middle school according to the following variables 0.Science (literary, scientific) 8. Sex (male - female) Third: the level of control site level among the students of the sample as a whole. Ra'aa: Measurement of differences in the level of the control site among junior students according to the following variables 0.Science (literary, scientific) 8. Sex (male - female) Fifth: Explain the relationship between the authoritarian personality and the locus of control among the students of the research sample. In order to achieve the objectives of the current research, the sample was randomized by the random method of 061 students from the middle school of the third directorate in accordance with the gender variables (male and female) and the academic and academic specialization (8105-8106) In order to measure the level of authoritarian personality in the students, the researcher built the measure of authoritarian personality, the number of paragraphs (51), after being presented to a committee of arbitrators and experts in this field, which is the apparent truth, extracted the strength of the standard of the scale paragraphs using the method of the two extremes and using the test of two independent samples, (1.15) except two paragraphs (2,82) were excluded from the scale because it is less than the level of significance required so that the number of paragraphs of the scale (42) (3) areas. After the calculation of the construction accuracy of the scale and the stability of the scale was calculated in the Vaccronbach method with a consistency coefficient (1.26). As for the measurement of the site of control, the researcher adopted the measure of sweetness 0121 (52), after it was modified. The necessary cytometric properties of the apparent honesty and the validity indicators of the structure of the two extremes were obtained and using Pearson correlation coefficient (2) were excluded because they were less than the required level of significance. If the scale became final (51), it was divided into (1) fields. The consistency of the scale was obtained by the Vaccronbach method with a consistency coefficient of 1.28. The researcher reached the following results: 0. The middle school students overcome them with a tolerant personality in their behavior. 8. There are no statistically significant differences in the authoritarian personality by gender. 3. There are no statistically significant differences for the authoritarian personality by variable (specialization). 4 - that the junior high school students in the direction of internal control and external in general. 5. There are statistically significant differences in the location of the locality according to the sex variable. The males tend to control their position internally. 6. There are no statistically significant differences in the location of the control by variable (specialization). 2. There is no statistically significant correlation between the authoritarian personality and the locus of control. In the light of the findings of the researcher, I made a number of conclusions, recommendations and suggestions mentioned in chapter .
Background: This in vitro study evaluated the effect of canal dryness and flaring on the accuracy of two electronic apex locators for working length (WL) determination. Materials and methods: Sixty extracted teeth were used, after access opening was done, the occlusal surface was flattened to create stable reference point. The teeth were randomly divided into two equal main groups of flared and unflared group each one of 30 teeth. The flaring was done with Gates Glidden drills. The two main groups were further subdivided into two subgroups: dry canal and wet canal using 5.25% sodium hypochlorite groups, Electronic WL of each sample was determined using both Root ZX and i-Root apex locator. Consequently, histologic WL was determined by shav

Show MoreThe results of analyzing BVRI CCD photometry of the spiral galaxies NGC 7339, NGC 7537, and NGC 7541 are presented using the observations acquired with the 1.88m Kottamia telescope (Egypt). The overall structure of the galaxies is analyzed together with isophotal contour maps. The surface brightness profiles of the galaxies are decomposed to bulge and disk components by fitting a de Vaucouleurs law for the bulge and an exponential law for the disk to obtain photometric parameters for each component. The corrected total and absolute magnitudes and integrated color are also obtained and found to be close to the published values. The radial profiles of ellipticity, major-axis position angle, and color are also obtained and discussed.
This study was designed to evaluate the effect of anesthesia on thyroid hormones (T3, T4, rT3), thyrotropin(TSH), and cortisol levels in patients undergoing major urological surgery. The study included fifty patients scheduled for elective major urological surgery where 70% of the patients underwent general anesthesia, while30% underwent regional anesthesia. All patients were in stable control general conditions. The study showed that the thyroid hormones, thyrotropin and cortisol levels were affected with general anesthesia more than regional. The levels of these hormones responded to anesthetics and surgical stresses. This response was thought to be mainly mediated by afferent neurogenic impulses from the area of injury. Therefore, ab

Thus, to fully address this imbalance, therapies should reduce bone resorption and promote bone formation. Dietary factors such as phyto-oestrogens and Zn have beneficial effects on osteoblast and osteoclast activity. However, the effect of combinations of these factors has not been widely studied. We therefore examined the effect of coumestrol, daidzein and genistein in the presence or absence of zinc sulphate (Zn) on osteoclast and osteoblast activity. Osteoclast differentiation and bone resorption were significantly reduced by coumestrol (10- 7 m), daidzein (10- 5 m) and genistein (10- 7 m); and this direct anti-osteoclastic action was unaffected by Zn (10-
... Show MoreThe object of the presented study was to monitor the changes that had happened in the main features (water, vegetation, and soil) of Al-Hammar Marsh region. To fulfill this goal, different satellite images had been used in different times, MSS 1973, TM 1990, ETM+ 2000, 2002, and MODIS 2009, 2010. A new technique of the unsupervised classification called (Color Extracting Technique) was used to classify the satellite images. MATLAP programming used the technique and separated Al-Hammar Marsh from other water features (rivers, irrigated lands, etc.) when calculated the changes in the water content of the study region. ArcGIS 9.3 (arcMAP, arcToolbox) were used to achieve this work and calculate area of each class.
Experimental results on harmonic distortions in 13.56 MHz RF Argon glow discharge using different grounded electrodes areas and electrodes spacing are presented. The experiment is carried out at four pressure values. RF power values used are between 20 and 90 watts. The results indicate significant increase in distortions at two specific values of the cone angle enclosing the two electrodes within its geometrical volume. The computation of the cone head angle gave the symmetry discharge or asymmetry as well as when the angle is small the condition is near symmetry discharge associated with decrease in the nonlinearity.
