3063) Pressure Loss in Outlet with Straight Vanes

Artificial Heart Rejects High Tech? Lessens Learnt from Non-pulsatile VAD with Straight Impeller Vanes

Despite the progresses in developing pulsatile impeller pump and impeller total heart, as well as in applying streamlined impeller vanes, the best results in application of artificial heart pumps have been achieved by nonpulsatile univentricular assist pump with straight impeller vanes until now. It seems all efforts and successes have been done in vain because artificial heart rejects Hi-Tech!...

A Simulation App based on reduced order modeling for manufacturing optimization of composite outlet guide vanes

Composites manufacturing processes usually involve multi-scale models in both space and time, highly non-linear and anisotropic behaviors, strongly coupled multi-physics and complex geometries [1]. In this framework, the use of simulation for real-time decision making directly in the manufacturing facility is still precluded nowadays [2]. In this work, a process-specific simulation tool based o...

Association between Tooth Loss and Cognitive Function among 3063 Chinese Older Adults: A Community-Based Study

BACKGROUND Oral health has been found to be associated with cognitive function in basic research and epidemiology studies. Most of these studies had no comprehensive clinical diagnosis on cognitive function. This study firstly reported the association between tooth loss and cognitive function among Chinese older population. METHODS The study included 3,063 community dwelling older adults aged...

Failure pressure of straight pipe with wall-thinning under internal pressure

The failure pressure of pipe with wall-thinning was investigated by using three-dimensional elastic-plastic finite element analyses (FEA). With careful modeling of the pipe and flaw geometry in addition to a proper stress-strain relation of the material, FEA could estimate the precise burst pressure obtained by the tests. FEA was conducted by assuming three kinds of materials: line pipe steel, ...
