The results of the CMS tracker alignment analysis are presented using the data from cosmic tracks, optical survey information, and the laser alignment system at the Tracker Integration Facility at CERN. During several months of operation in the spring and summer of 2007, about five million cosmic track events were collected with a partially active CMS Tracker. This allowed us to perform first a...
Using data from the German Socio-Economic Panel, we investigated the role of childbearing history in later-life health and mortality, paying particular attention to possible differences by sex and region. Higher parity is associated with better self-rated health in West German mothers and fathers aged 50+, but its relationship with East German women's physical health and survival is negative. E...
It has been known for over six decades that the dissolution of minute amounts of high molecular weight polymers in wall-bounded turbulent flows results in a dramatic reduction in turbulent skin friction by up to 70%. First principles simulations of turbulent flow of model polymer solutions can predict the drag reduction (DR) phenomenon. However, the essential dynamical interactions between the ...
Stiff ceramic platelets (or bricks) that are aligned and bonded to a second ductile phase with low volume fraction (mortar) are a promising pathway to produce stiff, hightoughness composites. For certain ranges of constituent properties, including those of some synthetic analogs to nacre, one can demonstrate that the deformation is dominated by relative brick motions. This paper describes simul...
Abstract: the article provides a calculation justification of proposed railway structure on reinforced concrete sleeper-free base, for which an analysis existing methodology calculating track strength is carried out, according to dynamic loads acting from rolling stock are determined. The applied sleeper-less structures and results measurements emerging stresses in substructure, measured depth ...
Navicular stress fractures mainly occur in sprinting and push-off athletes. Numerous predisposing factors have been implicated in their development. Within a six-week interval in the summer of 2009, twin brothers, both elite track and field athletes, presented to us with medial foot pain. Plain radiographs were negative but a radioisotope bone scan and CT scan revealed an incomplete navicular f...
