[Purpose] This study investigated the association between floating toe and toe grip strength. [Subjects and Methods] A total of 635 Japanese children aged 9-11 years participated in this study. Floating toe was evaluated using footprint images, while toe grip strength was measured using a toe grip dynamometer. All 1,270 feet were classified into a floating toe group and a normal toe group accor...
در سدهای خاکی سه فرآیند مختلف باعث ایجاد پدیده فرسایش داخلی می گردد که عبارت اند از فرسایش پیشرونده به سمت بدنه بالادست، نشت متمرکز و اشباع بودن مصالح سد. برای کاهش انرژی جریان نشتی اشباع در بدنه سد خاکی تدابیر مختلفی اتخاذ می گردد که عبارت اند از استفاده از هسته رسی نفوذناپذیر در سدهای منطقه بندی شده و استفاده از زهکش های افقی، دودکشی و پنجه در سدهای همگن. هدف از این پایان نامه بررسی زهکش افقی...
in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...
Untouched toe is a condition in which a toe does not touch the ground while standing. It is frequently observed in women even under physiological conditions. Deformities or symptoms of the toes are not observed in these women. The clinical significance of untouched toe has not been fully elucidated. Two hundred young healthy women were recruited into the present study after informed consent. We...
Abstract Cavitation is among the most complex and common damage occurring in spillway structures, which one of expensive parts a dam. The cavitation index, as efficient approaches, can be used to analyze this important hydraulic phenomenon. present study examines changes index caused by convergence angle an ogee spillway's sidewalls with arc plan. To end, was constructed on 1:50 scale. Then, it...
AIMS To assess the usefulness of three-dimensional transoesophageal echocardiography (3D-TOE) vs. two-dimensional (2D)-TOE in the evaluation of morphological and dynamic findings of aortic dissection, and compare the results with those obtained by multi-slice computed tomography (CT). METHODS AND RESULTS Twenty-six patients (21 men and 5 women, median age: 67 years, range: 28-74 years) diagno...
BACKGROUND Minimum toe clearance is a critical gait event because it coincides with peak forward velocity of the swing foot, and thus, there is an increased risk of tripping and falling. Trans-tibial amputees have increased risk of tripping compared to able-bodied individuals. Assessment of toe clearance during gait is thus clinically relevant. In able-bodied gait, minimum toe clearance increas...
