Collisions between bicycles and motor vehicles have caused severe life and property losses in many countries. The majority of bicycle-motor vehicle (BMV) accidents occur at intersections. In order to reduce the number of BMV accidents at intersections, a substantial understanding of the causal factors for the collisions is required. In this study, intersection BMV accidents were classified into...

-DC brush motor undergoes rigorous performance testing to predict the failures occurring. Acceptance test levels are set with margin expected flight/operations levels and qualification test levels are set above the expected operation levels to check for the survivability of DC brush motor in space. Performance testing is important to design and integration in a planned test process in which DC ...

This study examined the relationship between perceived physical competence and actual motor skill competence in African American preschool children at risk of school failure and/or developmental delay (N = 59). A secondary purpose was to determine gender differences and the accuracy of self-perceptions. All children completed a perceived physical competence subscale (Harter & Pike, 1984). Actua...

OBJECTIVE To examine the clinical and pathological factors associated with survival in autopsy-confirmed frontotemporal lobar degeneration (FTLD). METHODS The final analysis cohort included 71 patients with pathologically proven FTLD, excluding patients with clinical motor neuron disease (MND), evaluated at the University of Pennsylvania or at the University of California, San Francisco. We a...

The aim of the study was to identify the motor structures that determine achievement of top results in karate. The study included a sample of 85 karateka aged 18-29 years, competing as senior category athletes of the Croatian Karate Society. Fourteen motor tests (9 basic motor tests and 5 specific motor tests) were used to assess technical efficiency; fighting efficiency was estimated on the ba...

introduction: the most common manifestation of disturbed neurological function following stroke is motor weakness. muscle weakness has been implicated as a factor underlying deficits in gait performance in subjects who have suffered strokes . the purpose of this study was to investigate the relationship between involved lower extremity isometric muscle strength and two functional tasks: gait ab...

PURPOSE Cross-sectional evidence has demonstrated the importance of motor skill proficiency to physical activity participation, but it is unknown whether skill proficiency predicts subsequent physical activity. METHODS In 2000, children's proficiency in object control (kick, catch, throw) and locomotor (hop, side gallop, vertical jump) skills were assessed in a school intervention. In 2006/07...

OBJECTIVE To evaluate the effects of two different spinal isobaric levobupivacaine doses on spinal anesthesia characteristics and to find the minimum effective dose for surgery in patients undergoing transurethral resection (TUR) surgery. MATERIALS AND METHODS Fifty male patients undergoing TUR surgery were included in the study and were randomized into two equal groups: Group LB10 (n=25): 10...
