Voiding dysfunction is a common complication after radical pelvic surgery. To reduce this complication, nerve-sparing radical pelvic surgery was introduced. However, several patients experienced voiding difficulty despite nerve-sparing radical pelvic surgery. Thus, we investigated the functional and molecular changes of the bladder in rats, which demonstrated voiding dysfunction induced by nerv...

BACKGROUND The aim of this study was to construct an alternative classification system for occupational hand injuries based on etiologic mechanisms and to analyze the injury patterns resulting from various mechanisms. METHODS A retrospective analysis of patients operated between January 2005 and December 2007 in two hand surgery units staffed by a team of hand surgeons was made. The patient f...

in this paper, numerical simulation of frp composite cylinder tubes progressive crushing processes is conducted using ls-dyna. details on the numerical modeling strategy are given and discussed. it is found that triggers introduced in the numerical simulation can effectively model the bevel trigger at the end of the tubular specimens. it is also found that two-layer finite element model based o...

Metal matrix syntactic foams have been fabricated via counter-gravity infiltration of a packed bed of recycled expanded glass particles (EG) with A356 aluminum alloy. Particle shrinkage was studied and has been utilized to increase the particles' strength and tailor the mechanical properties of the expanded glass/metal syntactic foam (EG-MSF). The crushing strength of particles could be doubled...

Breakage occurs in several particulate systems that are simulated using the discrete element method (DEM), namely crushing and grinding as well inadvertently others include transportation, handling, mixing, separation geotechnical applications. Different approaches may be used to describe particle breakage DEM, but cases which influences significantly flow behaviour of material, imbedding descr...
