The high-temperature hydrogenation of CF4 in mixtures and H2 is assumed to involve the reaction H + → HF CF3. hydrogen atoms here are either formed by F CF3 (i.e., products thermal dissociation CF4) with H2, or H2. In former case, a complicated chain process started, while proceeds more direct way latter. This article determines rate constant CF3, characterizing its transition state quantum-che...

Background: Old age is accompanied by impaired musculoskeletal and nervous system, which may result in low mobility and cognitive problems. This study aims to evaluate the relationship between Physical Activity (PA) and Cognitive Function (CF) among the elderly population. Objectives: ?? Materials & Methods: This is a descriptive cross-sectional study conducted on 200 old people who were memb...

The present study investigated EFL teachers’ beliefs about oral corrective feedback (CF), their CF-provision practices across elementary and intermediate levels, and their beliefs-practices correspondence. To this end, the researchers conducted a semi-structured interview with the teachers and went on an overall forty-hour observation of their classrooms across both levels. The findings reveale...

This study evaluated causative factors in landslide susceptibility assessments and compared the performance of five models based on certainty factor (CF), logistic regression (LR), analytic hierarchy process (AHP), coupled CF–analytic (CF-AHP), CF–logistic (CF-LR). Kaiyang County, China, has complex geological conditions frequent disasters. Based field observations, nine influencing factors, na...

The Kolleru Lake is a famous Ramsar wetland of international significance. In this study heavy metal contents in water and sediment samples are reported. It is found that certain potentially toxic metal ions like chromium (4.5-80 µg/L), copper (1-20 µg/L), manganese (1-313 µg/L) and zinc (1.2-57 µg/L) are present in variable quantities in the lake water. When normalized with respect to concentr...
