Obesity has been related to postural instability during static standing. It remains unknown how obesity influences stability during dynamic movements like gait. The primary aim of this study was to investigate the effects of obesity on dynamic gait stability control in young adults during gait. Forty-four young adults (21 normal-weight and 23 obese) participated in this study. Participants walk...

Walking speed was timed for male and female pedestrians on a public sidewalk with fast, slow, or no music playing in the background (n = 20 per condition). Pedestrians in the fast music condition walked more rapidly than those in the other two conditions. Slow music did not reduce walking speed, relative to the no music condition. Walking speed did not differ by gender in any of the three condi...

People frequently analyze the actions of other people for the purpose of action coordination. To understand whether such self-relative action perception differs from other-relative action perception, the authors had observers either compare their own walking speed with that of a point-light walker or compare the walking speeds of 2 point-light walkers. In Experiment 1, observers walked, bicycle...

L- asparaginase enzyme is a renown enzyme due to its chemotherapeutic properties. This enzyme could also be employed in food processing technology. The present study aimed, optimizing the agitation and aeration rate in L-asparaginase production, using Candida utilis, ATCC 9950 in batch fermentation system. Beet molasses used as the carbohydrate source for enzyme production. A maximum asparagina...

In this article we are interested in the propagation speed for solution of hyperbolic boundary value problem in the WR class. Using the Holmgren principle, we show that this speed is finite and we are able to give an explicit expression for the maximal speed. Due to propagation phenomenon along the boundary specific to the WR class, the maximal speed can be larger than the propagation speed for...

This study investigated the temporal characteristics of gait initiation and gait termination. Ten nondisabled adult volunteers and ten people with unilateral transtibial limb loss performed starting and stopping for slow, normal, and fast walking speeds. We used kinematic and anthropomorphic data to determine the body center of mass (BCOM) position of each subject. The BCOM acceleration was der...

A substantial body of evidence points to a cue-based direct-access retrieval mechanism as a crucial component of skilled adult reading. We report two experiments aimed at examining whether poor readers are able to make use of the same retrieval mechanism. This is significant in light of findings that poor readers have difficulty retrieving linguistic information (e.g., Perfetti, 1985). Our expe...

This study recorded basic gait data from 656 healthy primary school-aged children (5-13 years) and 81 young adults (18-27 years) whilst walking over-ground across a level walkway at varying speed. It investigated the effect of gait speed and re-examined the issue of gait maturation. Participants completed 6-8 walks at self-selected slow, free and fast speed along a GAITRite walkway whilst weari...
