pH-sensitive gels: By using a cyclohexane-based scaffold to which various amino acid based substituents can be connected, low-molecular-weight compounds were obtained that can gelate water at very low concentrations. Their modular design (see picture: AA = amino acid(s), X = hydrophilic substituent, …

A new method to study sudden ankle inversions during human walking and jumping is presented. Ankle inversions of 258wereelicited using a box containing a trap door. During the gait task, subjects walked at a speed of 4 km/h. At a pre-programmed delayafter left heel strike, an electromagnet released the …

The quality and efficacy of political-military decision making and command depends to a large extent on the quality of the ongoing intelligence cycle. In other words, the more errors organizations and decision makers make during the ongoing cycles of information collection, analysis, information dissemination, …

The specific fibrinolytic properties of both high molecular weight (55 kd) and low molecular weight (30 kd) pro-urokinase from a monkey kidney cell culture were evaluated in a plasma clot lysis system and compared with those of human urokinase. The system was composed of a radiolabelled plasma clot immersed …

Heart-rate changes after transition from a supine to a standing posture were measured in 12 hypertensive and 12 normotensive primigravid women, in their last trimester of gestation. The subjects beat-to-beat heart-rate (HR) changes were recorded on both an ordinary cardiotocograph and on magnetic tape. …
