The German supreme court (BGH [1]) summons that by proclaiming four or five single measuring values of every blood alcohol determination to prove that the resulting standard deviation lies under the highest amount stated in the official verdict of 1989 (10). On the one hand the control of the proceedings must be guaranteed by the successful participation of the ring tests, yet on the other hand...

HYPOTHERMIA appears to have a definite place in surgery, and the production and control of this state is often the responsibility of the anaesthetist. It is, therefore, important that he should be familiar not only with the means by which cooling may be achieved, about which much has been written, but also with methods of measuring the temperature. The concept of "body temperature" whilst adequ...

While von Willebrand factor (vWF) is secreted from endothelial cells as a very large polymer, it circulates as a series of multimers that are reducible to a 225-kD polypeptide and three proteolytic fragments of 189, 176, and 140 kD. Cleavage at the Tyr-842/Met-843 bond of the vWF polypeptide creates the 140- and 176-kD fragments. In the process of understanding vWF multimer formation, the role ...

Analytical buckling models are important for down-hole operations to ensure the structural integrity of the drill string. A literature survey shows that most published analytical buckling models do not address the effects of inclination angle, boundary conditions or friction. The objective of this paper is to study the effects of boundary conditions, friction and angular inclination on the heli...
