PURPOSE To analyse change in distance between the humeral head and the glenoid fossa during traction in the maximally loose-packed position (MLPP) and the maximally closed-packed position (MCPP) under standardized conditions. SUBJECTS Six healthy subjects (three male and three female) with a mean age of 40.5 years, volunteered to participate in this study. MATERIALS AND METHODS Subjects wer...

Focal contacts act as mechanosensors allowing cells to respond to their biomechanical environment. Force transmission through newly formed contact sites is a highly dynamic process requiring a stable link between the intracellular cytoskeleton and the extracellular environment. To simultaneously investigate cellular traction forces in several individual maturing adhesion sites within the same c...

induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. speed identification is needed for the induction motor drives. however, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. ther...

It was previously demonstrated in isolated renal vascular smooth muscle cells (VSMCs) that integrin-mediated mechanotransduction triggers intracellular Ca(2+) mobilization, which is the hallmark of myogenic response in VSMCs. To test directly whether integrin-mediated mechanotransduction results in the myogenic response-like behavior in renal VSMCs, cell traction force microscopy was used to mo...

Traction spoofing is an important component of Global Navigation Satellite System (GNSS) intermediate attacks, and the traction scheme directly determines concealment spoofing. However, via conventional strategies can be easily detected using Time Arrival (TOA) power detection. Based on a BPSK-modulated signal, novel strategy code proposed to suppress part authentication signal form ideal corre...

Eight to 12 million people in United States have PAD (Allison et al. 2007). Only ~10% of patients with PAD have classic intermittent claudication (IC), ~50% have atypical leg symptoms and ~40% are asymptomatic (Hiatt 2001). Its prevalence significantly increases with age; 12 – 20% of those above the age of 65 years suffer from PAD (Ostchega al. 2007). The prevalence of PAD is similar in men and...

Intervention Preoperatively, patients were allocated to have a pillow placed under the ipsilateral thigh of the injured hip in the resting position of the extremity (n=50, pillow group) or to placement of 5 pounds of skin traction, applied by fitting a foam traction boot to the injured extremity and then suspending a 5 pound weight over a pulley at the foot of the bed (n=50, traction group). Al...

This article describes a novel splinting technique for the temporizing management of pediatric femur fractures. The J-splint is a reliable, simple, and rapidly applied splint that prevents many of the complications and pitfalls of other described temporizing measures, such as skeletal traction, skin traction, traction splinting, and posterior splinting. This technique of J-splinting femur fract...

the single wheel tester is an experimental device used to measure wheel forces when studying the relation of soil and wheel in a soil bin or in the field. in the model under development, a special frame holding the test wheel is connected to a loading carriage by two pairs of vertical rails and four rollers to provide a floating connection. by applying a driving torque to the test wheel shaft, ...
