G laucoma is a disease characterised by apoptotic ganglion cell death related, at least in part, to intraocular pressure. Any examination for glaucoma must therefore include some comment upon the health of these cells. Unfortunately, it is difficult to examine the ganglion cell layer ophthalmoscopically and so ophthalmologists typically rely on an analysis of a more visible ocular structure—the...

An anisotropic plasticity model is developed based on the non-associated flow rule with hardening. The combines non-quadratic yield function and quadratic plastic potential for orthogonal sheet metals. also expanded to properly reproduce cyclic effect during forming processes. simple formulations can contribute cost saving in parameter acquisition process implementation. was implemented into fi...

Abstract One of the commonly used metal forming processes is deep drawing, in which circular blanks are converted into a cup or shell with good surface finish. In this paper, the forming characteristics of Deep Draw Steel (DDS), a low-carbon steel with many engineering and automotive applications, is investigated by deep drawing. The forming limit diagram is a useful concept in favor of charact...

The intention of this research is to make analyze of deep drawing Cr-Ni stainless steel process. The research is related to forces that appear in machine tool during the process and also to material stress and its behaviour. The results are taken from two sources and their comparison is made. The first source of results are experiments made on hydraulic press, and the other source are results o...

BACKGROUND AND PURPOSE Total hip replacement (THR) with a reverse hybrid (RH), a combination of a cemented polyethylene cup and a cementless femoral stem, has been increasingly used in Scandinavia. In a randomized trial, we compared an RH THR with a proximal hydroxyapatite- (HA-) coated stem to a conventional cemented THR. Both groups received the same polyethylene cup. PATIENTS AND METHODS 5...
