nanocomposites made of carbon nanotube (cnt) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness. in this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated. first, fea models are created consisting of cnts with different shapes of straight and rope-...
Nanocomposites made of Carbon Nanotube (CNT) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness. In this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated. First, FEA models are created consisting of CNTs with different shapes of straight and rope-...
A bundle-shaped nano-supramolecular assembly possessing numerous luminescent cyclodextrin-Tb polyads and photosensitizing C(60) units has been constructed through the end-to-end inclusion complexation of cyclodextrin cavities with C(60)s, and its properties have been comprehensively characterized. Further investigations on the luminescence properties of the cyclodextrin-Tb polyad and the bundle...
Recent biomechanical studies have shown that an anatomic double-bundle posterior cruciate ligament (PCL) reconstruction is superior in restoring normal knee laxity compared with the conventional single-bundle isometric reconstruction. We describe a modification of an endoscopic PCL reconstruction technique using a double-bundle Y-shaped hamstring tendon graft. A double- or triple-bundle semiten...
A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which...
In this paper we construct a natural geometric structure for the space of shapes of a star-shaped polygon. Roughly speaking we find: The set of similarity classes of marked stars forms a hyperbolic right angle pentagon bundle over the space of external angle sets of inscribed pentagons. The assignment of the shape of its fiber to each angle set forms a hyperbolic plane bundle over the Teichmiil...
مکان یابی مناطق مناسب جهت دفن مواد زاید از اقدامات مهم در فرآیند مدیریت پسماندهای جامد شهری است. هدف از این تحقیق مکان یابی مناطق مناسب جهت دفن مواد زاید با استفاده از تحلیل سلسله مراتبی( ahp) و منطق فازی با بهره گیری از نرم افزار expert choice است. نخست هر یک از عوامل موثر بر مکان یابی در منطقه مورد مطالعه از قبیل شیب، کاربری اراضی، لیتولوژی، فاصله از راه، فاصله از راه آهن، فاصله از آبراهه، فا...
An actin filament bundle approximately 2-5 microns in length is present in the sperm of the blue mussel, Mytilus. In unfired sperm this bundle extends from the midpiece through a canal in the center of the nucleus to terminate on the membrane limiting the inside of the cone-shaped acrosomal vacuole. The bundle is composed of 45-65 actin filaments which are hexagonally packed and regularly cross...
