According to the European Union Water Framework Directive requirements, diatom metrics were used to assess the ecological status of surface waters in the Gaziantep central catchment (Turkey). A total of 42 diatom taxa were identified. A few environmental factors (especially lead, copper, orthophosphate, and chromium) played significant roles on the distribution of diatom assemblages among the sampling stations. The first two axes of the canonical correspondence analysis elucidated 91.6 % of the species–environment correlations with 13.9 % of the cumulative variance of species. The applied diatom indices (TIT – Trophic Index Turkey, TI – Trophic Index, and EPI-D – Eutrophication and/or Pollution Index-Diatom) showed different results in the evaluation of the ecological status of sampling stations. The results of TIT and TI indicate that Kıratlı creek has a poor ecological condition, while a good ecological condition was reported by the EPI-D index. This creek is associated with relatively high nutrient values (e.g., 91.1 µg L–1 P-PO4, 8.6 mg L–1 N-NO3, 0.59 mg L–1 N-NO2, and 97.5 mg L–1 SO4) and characterized by pollution-tolerant taxa (e.g., Amphora ovalis Cocconeis placentula Cyclotella meneghiniana Gomphonema parvulum Fragilaria biceps, and Navicula trivialis). The results of the Spearman correlation analysis reveal that TIT has a significant positive correlation with P-PO4 (p < 0.01, r = 0.780), conductivity (p < 0.01, r = 0.769), N-NO3 (p < 0.01, r = 0.714), and N-NO2 (p < 0.01, r = 0.778). Our results show that TIT is a suitable diatom metric to assess the ecological status of surface waters in the Gaziantep central catchment and for the Mediterranean region in general.
The current research examines the employment of indicators of stereotypes and the dimensions of organizational clarification to achieve planned organizational behaviour on a sample of employees in a number of departments of the Faculties of Engineering, University of Kufa, for a sample of (122) teaching staff. This research proposes the use of positive indicators of stereotypes for both the organization and employees and their awareness of what they want to obtain and what should be done for both parties and the removal of organizational clarity represented by the functional dimension that explores to what degree the employee's understanding of the internal strategy of the organization and the strategic dimension that searches fo

There is no statistically significant difference at the significance level (0.05) between the average differences in the posttest scores of the experimental group taught according to Daniel's model and the control group taught according to the traditional method in the measure of critical thinking. 2. There is no statistically significant difference at the significance level (0.05) between the average differences in the preand post-tests scores of the experimental group taught according to Daniel's model in the measure of critical thinking.

There is evidence suggesting that consuming high level s of protein may in fact have negative side effects for health. The current study included 29 young Iraqi building muscles in two different groups (taken and not protein supplements) (age range=17-31 years), the cases were selected from family, friends, college students, and Gyms), from November 2014 to March 2015. A careful history was obtained from each volunteer including age, duration of sports, type of supplements, and family history of diseases. Some biochemical parameters like (glucose, urea, uric acid, creatinine, bilirubin, serum protei
