case report: we report a 44-year-old man with right femoral nerve palsy following delayed reduction of an anterior dislocation of hip. conclusion: two months after closed reduction, complete clinical recovery of right femoral nerve was achieved and the patient was able to resume his job. introduction: incidence of nerve injury in traumatic hip dislocations is up to 10 %. sciatic nerve is the mo...

In this work, doping-defect interactions relevant to self-compensation in p-type GaN were investigated using atom probe tomography. The 3D visualization of ion distribution revealed the formation spherical Mg-rich clusters and segregation Mg dopant towards dislocations MOCVD-grown GaN:Mg. Impurities related self-compensation, such as oxygen hydrogen, identified detected adjacent dislocations. C...

Solutions are obtained for the stress and pore pressure due to sudden introduction of plane strain dislocations in a linear elastic, fluid-infiltrated, Biot, solid. Previous solutions have required that the pore fluid pressure and its gradient be continuous. Consequently, the antisymmetry (symmetry) ofthe pore pressure p about y = Orequires that this plane be permeable (p = 0) for a shear dislo...

The dislocation densities, surface morphology, and strain of Gal _ x In" As/GaAs epitaxial interfaces as a function of indium composition and layer thickness have been investigated by transmission electron microscopy, medium energy ion blocking, and double-crystal x-ray diffractometry. The electron microscopy shows that in the thinnest dislocated films (90 and 160 nm, x = 0.07) 60· a dislocatio...

A series of Ge quantum dot superlattices were prepared to study the relationship of the dot morphology evolution with the number of layers. Strain relaxation was observed in thicker films and the dots transited from broad size distribution to size equalization and eventually to broad size distribution again as a result of the generation of threading dislocations in the quantum dot superlattice ...

Hydride vapour phase epitaxy grown allepitaxial p-i-n structures were studied by synchrotron X-ray topography. Three types of process induced dislocations were found: short threading dislocations, long straight interfacial dislocations and circular arc dislocations. The majority of the dislocations observed are short straight threading dislocations, the density of which is typically about 5000 ...

a 25-yr-old iranian woman with incomplete abortion who was diagnosed and scheduled for dilatation and curettage procedures under general anesthesia. after premedication with fentanyl 50µg and midazolam 2mg and enough pre-oxygenation, anesthesia was induced by sodium thiopental 250 mg and succynilcholine 60 mg with mask ventilation. after completion of procedure, the patient had a period of lary...
