Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The removal of fine materials from surface water represents a challenge. This research tries to improve the efficiency of flocculation process of low turbidity water by dividing the process into stage of gradual descending velocity gradient. A three stages flocculator model of continuous flow was designed and constructed. Combinations of three levels of velocity gradient of 60, 45 and 30 sec-1 were applied in the experiments in descending order. Tigris river water was used as raw water with 8-12 NTU turbidity. Alum was used as a coagulant at the optimum dosage. Turbidity removal percent was considered as an indicator of flocculation efficiency. The results showed a significant increase in turbidity removal percent with the decrease of velocity gradient at stage III. On the other hand, velocity gradient at stage I shows a direct relationship with turbidity removal, while the relationship is not clear at stage II. The best turbidity removal percent of more than 80% was obtained by the combinations 60*30*30 and 45*45* 30 sec-1. A regression model shows that velocity gradient at stage III was the most contributor to turbidity removal variation. The research recommended descending gradual velocity gradient flocculation at two stages
This study was conducted to analysis the effect of Time-OF-Day on physical fitness components for students of Physical Education Department-Duhok University.The aim of this study was to compare the level of some physical fitness components between students of the morning shift and evening shift studies of the first stage in the college of Physical Education, The selected variables for the study were speed by (sprint 60 M test), abdominal endurance by (Abdominal muscles test) , anaerobic power and agility by (5-m multiple shuttle run test) and explosive strength of the arms by (Medicine ball throw test) of both groups were compared by using the statistical package for Scientific Sciences SPSS. The data of this study is not normally distributed. Therefore, non-parametric methods were used to analyze this data (Chi-square and Phi methods). Statistical analysis methods were applied to compare between the students’ level in the morning shift and evening shift. When the data were collected for both shift from the physical education department in Duhok University. significant relation was found between all variables and Time-OF-Day except the year of study as there is no significant relation between Time-OF-Day and the year of study
