Due to recent increasing water demand, planning and projecting of water resources has resulted in increased costs. There-fore, it is important to obtain optimum results in project planning. In this study, dimensioning of open channels used espe-cially for irrigation purposes has been studied using a particle swarm optimization algorithm to investigate optimum base width, channel height, and slope angles. The results are summarized in graphs and tables. In the study, it was found that the optimum slope angle varied between 0. 200. 45. Furthermore, it was found that increasing the slope angle significant-ly increased costs. Finally, the increase in flow increases costs but the rate of increase diminishes.

Aksakal, B.; Demirel, M.
Background: Syntesizing alternative bone graft materials are important in biomedical applications. Their morphology, mechanical properties and cell viability plays an important role in tissue engineering. OBJECTIVE: Bioglass (B) based bone grafts with Gelatin (G) substitution were syntesized via the sol-gel method and were compared with various Gelatin and Bioglass concentrations (wt%). METHODS: Syntesized bone grafts were characterized by Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD) to show the structural and morphological changes of the fabricated B-based bone grafts. RESULTS: It was demonstrated that the concentration of pore size increased with increasing amounts of Gelatin in wt%. The biograft-B40G20 produced the highest flexture strength and hardness. Increasing the pore size caused a decrease in hardness and flexture stress of B-based biografts. CONCLUSIONS: Cell viability tests were conducted on the fabricated biografts and it was shown that the cell viability increased in fabricated B-based bone grafts.
