A comparison of the values obtained with experimental data on noneroding velocity in article shows that soil erosion experiments took place much earlier because our were carried out trapezoidal channels, based wide rectangular channels.

among the all parameters affecting the performance of a downhole de-oiling hydrocyclone, the investigation of internal flow field deserves more attempts especially in the petroleum industry. in this study, the effects of inlet flow rate, inlet oil volume fraction, and oil droplet diameter on the separation efficiency and pressure drop ratio have been investigated along the hydrocyclone body. al...

BACKGROUND AND AIM: Hyposalivation can cause many difficulties for patients like opportunistic infections such as candidiasis, mouth sores, and dysphagia as well as reduced quality of life (QOL). Methods such as using sugar-free chewing gum are recommended to treat this complication. Mastic is a natural substance and since it has various properties in addition ...

conclusions this study indicated that the delivery rate accuracy of elastomeric infusion pumps is preserved after repeated usage. these laboratory findings suggested that elastomeric pumps could be safely refilled in the successive days to provide postoperative analgesia. results the mean flow rate in the three series of measurements showed a gradual increase; however, the difference was not st...
