Abstract A new steel chemical composition is combined with a press hardening process, in which die-quenching interrupted by opening the forming tool to permit slow cooling of hot formed part through anisothermal bainitic ferrite transformation. This promotes carbon partitioning austenite before re-closed and resumed near-ambient temperature. The final microstructure predominantly dispersions ma...

The shell-breaking behavior of the crabs 0:iu.y verrec~uxri Saussure 1853 and Eriphia .squtmwta. Stimpson 1859 from the Bay of Panama is described. The master claws of both these crabs are well designed for breaking shells. Small shells, relative to the size of a crab predator, are crushed by progressively breaking off larger segments of a shell’s apex, while larger shells are peeled by inserti...

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...

purpose: to evaluate the effect of childhood corneal opacity on the anteroposterior length of the globe in adulthood. methods: twenty-three patients with significant unilateral corneal opacity which had developed before the age of 6 years and the normal fellow eyes (controls) were evaluated. a comprehensive ocular examination including measurement of anterioposterior length and anterior chamber...

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...
