Much of the attention on simulation software in recent years has been focused on the modelling of bulk metal forming processes such as forging, rolling and extrusion. However, there are numerous applications for the simulation of sheet forming processes and indeed many pressings suppliers in the automotive industry are more advanced in the use of simulation than their forging counterparts. The ...

The present invention provides a new process for the preparation of 2S,3S-N-isobutyl-N-(2-hydroxy-3-amino-4phenylbutyl)-p-nitrobenzenesulfonylamide hydrochloride, wherein this compound is prepared directly from the chloromethylalcohol. Importantly, the process of the present invention results in higher yields of 2S,3S-N-isobutyl-N-(2hydroxy -3 -amino -4-phenylbu tyl) -pnitrobenzenesulfonylamide...

Abstract During deep drawing processes of fiber metal laminates, such as the newly developed in-situ hybridization process, fibers and sheets come into contact while dry fabric is infiltrated by a reactive matrix system. The viscosity increases polymerization starts during deep-drawing. In laminate drawn thermoplastic system injected glass layer in resin transfer molding process. forming lamina...

During the course of drawing up this information sheet we took into account to comply with the provisions of Directive 2011/83/EU on consumer rights, Directive on labelling, presentation and advertising of foodstuffs (2000/13/EC) and the Unfair Commercial Practices Directive (2005/29/EC) with respect to the aim of the above regulations to provide the consumers with the most possible detailed in...

OBJECTIVES To reduce the contamination rate of blood cultures taken in the Accident and Emergency (A&E) department. METHODS The standard blood culture sampling kit was supplemented with an instruction sheet on the optimal method for drawing blood cultures and a large 62% ethyl alcohol impregnated wipe. RESULTS There was a statistically significant reduction in the number of contaminants (p ...

A combined experimental and numerical study of the effect of temperature on anisotropy in warm forming of AA 6016-T4 aluminum was performed. The anisotropy coefficients of the Vegter yield function were calculated from crystal plasticity models with an adequate combination of extra slip systems. Curve fitting was used to fit the anisotropy coefficients calculated at discrete temperatures. This ...

Abstract In forming processes, friction is a local phenomenon influenced by the contact conditions at tool-sheet metal interface. A multi-scale model applicable for coated sheets developed boundary lubrication regime which accounts physical behavior of coating and measured surface topographies sheet tools. The patches therefore real area determined interface different loading conditions. single...

This paper summarizes our theoretical understanding of supernova events in a “back of the envelope” way. It is intended to aid in the recognition and understanding of those events which are not “standard”, and which may provide the most insight.

In German art history, drawing assumed a leading role in two periods: around 1500, the age of Dürer, and around 1800, the age of Goethe or the Romantic era. The correspondences between ideas, themes, and practices in the drawings of these periods are the subject of this article. I will first discuss the interesting phenomenon of the parallels between the ages of Dürer and Goethe in the developm...
