Original scientific paper In the pipelines of water supply systems, the water hammer phenomenon often arises during rapid unsteady developments. Pipelines are mostly protected using an air vessel, which is designed by means of equations for oscillations of water mass. In this study, an analysis is made of the impact of pressure increases caused by water hammer on pressure variations in pipeline...
This essay introduces a new featured section, to be published in Small Axe annually, that explores the critical vocabulary of field Caribbean studies.
PURPOSE Vessel damage after clamping may affect the success of surgical operations. A new pressure controlled clamp (SMA clamp) was designed using super elastic property of shape memory alloy (SMA) to realize atraumatic vessel occlusion. The ability and biological effect of the SMA clamp to control pressure was investigated in vivo. METHODS The loading-displacement curves of the SMA clamps (e...
The central aorta acts as a compliant tube that buffers and conducts pulsatile ventricular output (7) and contributes mostly to total compliance of the arterial tree. The mathematical model introduced by O. Frank (7) describing pulse wave propagation and arterial mechanical properties assumes that the arterial tree is an elastic chamber (windkessel) in which the diastolic pressure decays expone...
