Bioethics has become a prominent part of the American landscape. In only a few short decades this interdisciplinary field permeated academia and the public sphere. Despite the recent scholarly effort to chronicle its history, there is still quite a bit of controversy surrounding bioethics’ origin and rapid evolution. Bioethics’ emergence has already been thoroughly examined through the lens of ...

In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...

shape error due to elastic recovery of formed part in unloading known as springback, is one of the most important problems of tool design in sheet metal forming processes. many researches have been performed for proposing an efficient method to decrease or compensate springback error in sheet forming processes. these methods are usually based on iterative finite element algorithms. in this pape...

conclusion these data show that the identified gene encoded tet resistance gene as mfs–type multi-substrate efflux transporter, which contributes to intrinsic resistance on range of structurally unrelated compounds in salmonella species. background tetracyclines (tcs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. these antibiotics ev...

frictional shear stress is usually determined by utilizing the coefficient of friction or the constant friction factor models. the present study deals with finite element analysis of double cup extrusion process to determine the relationship between constant friction factor (m) and coefficient of friction (µ), since the metal flow in this process is very sensitive to frictional conditions. ther...

determination of the deformation length is one of the first steps in roll forming design. roll forming industries are very interested in explicit simple relationsfor prediction the deformation length without using trail-and-error methods at workshop or time consuming finite element simulations. in this paper, elastic properties and work-hardening behaviour of the strip are considered in additio...
