BACKGROUND The purpose of this study was to investigate the lifting characteristics of elders with functional limitations using burden lifting smoothness, trunk angular momentum, and back and hip torque, and to correlate these characteristics with strength and functional measures. METHODS Thirty elders (65-89 years old) consented to biomechanical analysis of lifting, gait, and chair rise, and...

Abstract The process of ground motion selection and scaling is an integral part hazard‐ risk‐consistent seismic demand analysis structures. Due to the lack records that naturally possess high amplitude intensity, research community generally relies on match a target hazard intensity level. factors used are frequently as 10. criticism received in previous studies, extent its has become matter de...

Peak aortic blood acceleration is recognized to be a sensitive index of global left ventricular performance. In the present study peak acceleration was assessed noninvasively in patients with a continuous-wave Doppler velocity meter. Peak aortic blood velocity and peak blood acceleration were measured by placing the ultrasonic transducer at the suprasternal notch. Measurements were obtained in ...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

objectives: to evaluate the reliability of head and trunk acceleration measured by mtx sensors during walking on level and irregular surfaces and to compare the differences between healthy young and old adults. methods: participants were 20 young female university students and 20 non-faller elderly women in iran, 2013. two mtx sensors were used to measure head and trunk accelerations in the ver...

Previous studies of respiratory disorders in workers exposed to pulverised fuel ash (PFA) have been confined to radiological effects that were found to be minimal. The present survey included 268 men (88% of the defined population) with a history of more than 10 years exposure to PFA in six power stations in the south east of England. Respiratory questionnaires with full occupational histories ...
