We presented a female patient with RA complaining of progressive pain, swelling, and crepitation of the knee joints that was diagnosed with bilateral synovial chondromatosis (SC) of both knees. Radiographies revealed characteristic findings of SC including multiple calcified multifaceted loose bodies within both knees. Removal of cartilaginous segments as well as total synovectomy was performed...

BACKGROUND The risk factors for developmental dysplasia of the hip (DDH) in infants from unifetal pregnancies are commonly known. Many of these factors also apply to multiple pregnancies. The aim of this paper was to evaluate the influence of selected, widely recognized DDH risk factors in unifetal pregnancy on the development of hip joints in infants from multiple pregnancies. The following ri...

The International Thermonuclear Experiment Reactor (ITER) Thermal shield (TS) serves as a cryogenic heat exchanger to maintain the thermal stability of ITER superconducting magnet coil, which is critical control plasma during operation device. TS composed long-length 316L stainless steel (SS) and copper brazed joints. In this case, feasible fabrication design for CCS presented, accomplished by ...

Pipe vibration is often excited in the deep ocean by ship motions, wave forces and vortex shedding. Elastic joints along the pipe are modeled in an attempt to move the resonance frequencies away from the pipe system. The numerical examples focus on the investigation of single and multiple elastic joints along a long pipe and their effect on three-dimensional (3-D) nonlinear coupled pipe respons...

Optimising debris-resisting barriers is of paramount importance on constructing cost-effective and eco-friendly mitigation works. Multiple with basal clearance can potentially serve as an optimal approach because they facilitate flow energy dissipation, reduce the impact force each barrier, ease maintenance resist a large volume. However, design multiple remains empirical. In this study, physic...

in present paper, a point to point optimal path is planned for a mobile manipulator with flexible links and joints. for this purpose, a perfect dynamic modeling is performed for mobile manipulators considering large deformation in links, shear effects, elastic joints, effect of gravitation, and non-holonomic constraints. to study large deformation of links, non-linear relation of displacement-s...
