Introduction: Proton therapy is a type of radiation treatment that it uses protons to treat cancer. Because of the protons’ unique ability to distribute the radiation dose more directly to the tumor, it minimizes the damage to nearby healthy tissues. The rate of energy loss by the ion in the target is called stopping power. The total stopping power is sum nuclear and electroni...

Demand of electricity varies on hourly basis whereas the production is quite inelastic. This results in heavy fluctuation in the price of the electrical energy. Consequently many power companies have started offering time based tariffs. Data centers and industrial consumers of electricity are penalized for the peak power demand of their loads. To shave the peak power demand, a battery buffer ca...

Despite the inclusion of beach volleyball as an Olympic discipline with a fully professional world tour, little research has been published that has examined the physical qualities of internationally competitive athletes. Thirty international-standard beach volleyball athletes (14 male, 16 female) performed countermovement jumps (CMJ) and squat jumps (SJ) on a force platform. Ground reaction fo...

The popularity of running and consequently of running injuries has increased tends to develop shoe sole constructions aiming at preventing different injuries. The purpose of this study was to investigate the effect of shoe outsole containing nanoclay particles on knee joint power during stance phase of running. Fourteen healthy male shod runners run 3 times at 3.5 m.s-1 under three shoe condi...
