Possibilities to influence the deep drawing process during its duration are limited and generally consist of influences at the flange of the thin sheet, mainly by the contact pressure (the blank holding force). The common characteristics of previous... see more

The precise knowledge of frictional behavior is highly relevant for accurate modelling in sheet metal forming simulations. This allows e.g., the precise prediction of restraining forces which, in turn, determines an optimal draw bead strategy and blank-te... see more

The present work investigated the permeation of indium ions through a polymer inclusion membrane (PIM), prepared with cellulose triacetate (CTA) as the base polymer, tris(2-butoxyethyl) phosphate (TBEP) as the plasticizer and di-(2-ethylhexyl)phosphoric a... see more

In this study quantitative interpretation of some 14 Vertical Electrical Sounding (VES) points using the Schlumberger array and data from 10 boreholes were applied to study the aquifer geoelectrical/hydrogeological parameters in the southern governorates ... see more

Upgrading crude yellow cake was done by 0.05 M Tris 2-ethylhexyl Phosphate / kerosene from 5 M nitrate solution.  More than 98 % of uranium extracted after 5 stages of contact, shaking time 5 minutes and volume phase ratio 1/1. Uranium stripping effi... see more

To improve current collector dynamic characteristics, it is offered to use as basis graphite contact inserts whose side parts are coated by copper or aluminium. It leads to the reduction of the detachment factor and to the increase of current.
