This experiment used a Coulomb balance to determine how the Coulomb force is dependent on the charge of two objects and the distance between these charges. In the first part of the experiment, the charges on the conductive spheres were kept constant, while the distance was varied. The angle at which the suspended sphere returned to its original position was recorded ten times for eight differen...

Purpose The purpose of this study was to determine the results of mobile bearing unicompartmental knee arthroplasty (UKA) with an intentionally increased flexion angle of the femoral component in patients requiring high flexion. Materials and Methods We investigated 45 knees treated by UKA. Clinically, we measured the range of motion (ROM) and the American Knee Society (AKS) score preoperativ...

Due to the increasing energy needs and limited resources that are depleted, more importance is given renewable sources their use with highest efficiency in many areas. In order benefit from solar energy, which one of most important sources, efficiency, various parameters must be optimized. this study, optimization photovoltaic (PV) panel angle emphasized. By using values radiation incident on h...

In accordance with the specifications for the design of the gas station lighting system, the original lighting system was transformed into the overall solar-powered LED lighting system. The original lighting was replaced by using the same illumination LED lamps. Calculations were made to determine the optimum tilt angle of solar components. Based on the reasonable LOLP rate, solar module and ba...

[1] We study channelization and slope destabilization driven by subsurface (groundwater) flow in a laboratory experiment. The pressure of the water entering the sand pile from below as well as the slope of the sand pile are varied. We present quantitative understanding of the three modes of sediment mobilization in this experiment: surface erosion, fluidization, and slumping. The onset of erosi...
