The present study examines the dynamic behavior of a variable displacement wobble plate compressor which makes it possible to control the cooling capacity continuously. The continuous cooling capacity control Is achieved by the complicated motion of the piston, the piston rod, the wobble plate, the rotating journal and the drive shaft. In order to analyze the complicated motion of each moving e...

BACKGROUND Hip displacement is the second most common deformity in cerebral palsy (CP). The risk for hip displacement is related to the Gross Motor Function Classification System (GMFCS). Recently, the head-shaft angle (HSA) has been identified as a predictor for hip displacement and the aim of this study is to assess the predictive value of the HSA for hip displacement in CP. METHODS In this...

We report a rare case of dislocation of second to fourth carpometacarpal (CMC) joints of the right hand with combined dorsal and ulnarward displacement of the second to fourth digits and fracture of the shaft of the first metacarpal associated with degloving injury. These injuries were diagnosed early and treated successfully with closed reduction and internal fixation using Kirschner wires. Th...

The configuration of a marine propulsion system is selected with regard to the maximum power resulting from its maximum design speed and displacement. The propulsion systems of high speed vessels use three or even four propellers, and each propulsion unit may be multi-engine. High speed vessels are designed for maximum speeds, but their factual exploitation speed parameters are usually consider...

Pursuant to the high usage of rotating the disk in aircraft gas turbine engine, turbo pumps in oil and gas industries, steam and gas turbines in power plants, marine gas turbine and other industrial rotary machines designing and getting under the mechanical and thermal loading casued this design and analysis to be as a special significance. These disks are subjected to mechanical and thermal lo...

In fractures of the femoral neck there may be displacement of different types accounting for the well recognised abduction and adduction fractures with valgus and varus displacement (Nystrom 1938). Between these types there is a transitional form that was described by Waldenstr#{246}m (1924) as the “ fracture impacted in adduction “ and by this author as “ the intermediary type “ (Linton 1944)....
