During the Cold War the United States developed an espionage style that reflected its love affair with technology (technophilia) whereas the Soviet Union and the East Bloc continued a tradition of using humans to collect intelligence. This essay places the origins and development of these espionage styles during the Cold War in historical and social context, and assesses their strengths and wea...

Cold drawing is widely applied in the industrial production of seamless tubes, employed for various mechanical applications. During pre-processing, deviations in tools and their adjustment lead to inhomogeneities in the geometry of the tubes and cause a gradient in residuals. In this paper a three dimensional finite element (3D-FE)-model is presented which was developed to calculate the change ...

In this work, the influence of composition and cold-drawing on nanoand micro-scale morphology and tensile mechanical properties of PE/organoclay nanocomposite fibers was investigated. Nanocomposites were prepared by melt compounding in a twin-screw extruder, using a maleic anhydride grafted linear low density polyethylene (LLDPE–g–MA) and an organomodified montmorillonite (Dellite 67G) at three...
