Unloaded rat Achilles tendons continue to grow, but lose viscoelasticity.
Tendons can function as springs and thereby preserve energy during cyclic loading. They might also have damping properties, which, hypothetically, could reduce risk of microinjuries due to fatigue at sites of local stress concentration within the tendon. At mechanical testing, damping will appear as hysteresis. How is damping influenced by training or disuse? Does training decrease hysteresis, ...

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
Substantial creep in healing human Achilles tendons
The early tendon regenerate after an Achilles tendon rupture is a watery tissue, likely to show time-dependent deformation during load. To our knowledge the extent of such deformation has not previously been estimated in humans. Estimations of mechanical properties of intact tendons have usually applied ultrasonography1. This method measures the entire length of the tendon, and is therefore unl...
متن کاملHistopathological, biomechanical, and behavioral pain findings of Achilles tendinopathy using an animal model of overuse injury
Animal models of forced running are used to study overuse tendinopathy, a common health problem for which clear evidence for effective and accessible treatments is still lacking. In these models, pain evaluation is necessary to better understand the disease, help design and evaluate therapies, and ensure humane treatment of the animals. Therefore, the main objective of this study was to evaluat...
