The fluid force on a sphere with dimples has been investigated in Reynolds number range from 0.4×10 5 to 1.7×10 5. Two spheres of diameter 42.6 and 100mm were studied with 328 dimples on their surface. In the present study, the dimples in the form of three types (arc, cone and trapezoid type) were used. And more, the depth ratio of arc type dimple (k/d) (k(More)
PURPOSE Some reports suggest that the high level expression of thymidine phosphorylase (TP), which is known as one of angiogenic factors, is related to high malignancy and also poor prognosis in the field of gastrointestinal cancer. So the authors investigated the expression of TP in bladder cancer. MATERIALS AND METHODS The expression of TP in cancer(More)
The purpose of this study is to investigate the characteristics of the flow through the Jonangu channel which is used for ceremonial game called as 'Kyokusui-no-En' in Japanese. The geometry of the channel is measured, a visualization technique is used to measure the actual flow characteristics, and then a numerical flow model is used to represent the flow(More)
PURPOSE A commercial 6D carbon fiber radiotherapy treatment couch (Imaging Couch Top, BrainLAB) has recently been reported to attenuate photon beams and increase skin dose. To prevent skin toxicity and ensure the target dose, it is important to correct the attenuation properties of the treatment couch with the treatment planning system (TPS). In this study,(More)
