Olympic weightlifting movements and their variations are believed to be among the most effective ways to improve power, strength, and speed in athletes. This study investigated the effects of two Olympic weightlifting variations (hang cleans and hang snatches), on power (vertical jump height), strength (1RM back squat), and speed (40-yard sprint) in female collegiate athletes. 23 NCAA Division ...
A novel method of measuring the relative headmedium spacing based on a measurement in the servo sectors is developed and simulated using a read back signal model. The spacing measurement is tested experimentally on a spin stand where the flying height is varied using the resistance heater element in a thermal flying height control slider. In addition, voltage step response measurements were obt...
OBJECTIVE To investigate the risk factors for low back pain in hospital nurses, with particular emphasis on the role of specific nursing activities. METHODS A cross sectional survey of 2405 nurses employed by a group of teaching hospitals was carried out. Self administered questionnaires were used to collect information about occupational activities, non-occupational risk factors for back sym...
Carpet weavers suffer from musculoskeletal problems mainly attributed to poor working postures. Their posture is mostly constrained by the design of workstations. This study was conducted to investigate the effects of 2 design parameters (weaving height and seat type) on postural variables and subjective experience, and to develop guidelines for workstation adjustments. At an experimental works...
Reconstruction of Global Monthly Upper-Level Temperature and Geopotential Height Fields Back to 1880
This report describes parallelization techniques for accelerating a broad class of recurrences on processors with instruction level parallelism. We introduce a new technique, called blocked back-substitution, which has lower operation count and higher performance than previous methods. The blocked back-substitution technique requires unrolling and non-symmetric optimization of innermost loop it...
LTCC-M (Low Temperature Co-fired Ceramic on Metal) technology is described in terms of structural characteristics, materials and processes. Much works on material systems to minimize thermal mismatches and barrier formation processes to have uniform height and shape are introduced and some results from the fabrication of back panels having barrier ribs in 165 μm pitch are shown. Finally, furthe...
The aim of this investigation was to analyze the external forces and biomechanical loading on the musculoskeletal system during wheelchair pushing, in relation to different push handle heights. In addition, recommendations for wheelchair pushing in accordance with push handle height are made. Eight young, female subjects carried out three different wheelchair transport tasks at five different p...
PURPOSE Many factors such as lumbar instability and spinopelvic alignment are associated with low back pain. Our purpose was to analyze the pelvic incidence - one of spinopelvic alignment parameters- and spine instability correlations in patients with chronic low back pain. METHODS Fifty-two patients suffering from chronic low back pain entered this case control study. Lateral spine radiograp...
