The emerging applications of nanoelectromechanical systems (NEMS) in ground-state cooling, quantum manipulation, communication devices, etc., call for a nanoresonator with high frequency, quality factor, and tunability, as well as easy integration. Here we show that such a nanoresonator can be achieved by using a unique assembly technique that transfers the stressed inner shell of carbon nanotubes...
Object: There are several therapies for rupture of long head of biceps tendon, including biceps tenotomy. However, there is still a disagreement on it, because this procedure may change thebiomechanical properties of shoulder and lead to degeneration of rotator cuff. The purpose of this study is to determine the change of stress and strain on shoulder with or without biceps tendon when the joint is...
We observed structure and form of adult anulus fibrous of lumbar intervertebral disc at fibrous layer level. Anulus fibrosus of lumbar interverbral disc was delaminated microsurgical technique. 8 testing points were taken in each layer and the angles between their fibers going and horizontal plane were measured. We got the results: Fiber going angle at each measurement point ceaselessly increased...
