A clear understanding of the dependence of mechanical properties of bone remains a task not fully achieved. In order to estimate the mechanical properties in bones for implants, pore cross-section area, calcium content, and apparent density were measured in trabecular bone samples for human implants. Samples of fresh and defatted bone tissue, extracted from one year old bovines, were cut in lon...

Background: The relationship between airway and facial morphology is one of the components of facial skeleton that has extensively been debated in the literature. Studying this relationship to find conclusive results has clinical importance. Hence, the current study was carried out with the objective to determine association between saddle angle and the cross-section area of upper airway as ass...

in this paper, a novel approximate solution to determine the nusselt number for thermally developed, slug (low-prandtl), laminar, single phase flow in channels of arbitrary cross section is presented. using the saint-venant principle in torsion of beams, it is shown that the thermally developed nusselt number for low-prandtl flow is only a function of the geometrical parameters of the channel c...

We calculate the cross section for the dissociation of J/ψ by kaons within the framework of a meson exchange model. We find that, depending on the values of the coupling constants used, the cross section can vary from 5 mb to 30 mb at √ s ∼ 5 GeV. In relativistic heavy ion collisions J/ψ suppression has been recognized as an important tool to identify the possible phase transition to quark-gluo...

از آنجائیکه فاکتور تجمع نحوه توزیع الیاف در سطح مقطع نخ را بیان می کند در این تحقیق این فاکتور مورد مطالعه قرار گرفت روش مورد استفاده جهت اندازه گیری فاکتور تجمع الیاف در سطح مقطع نخ پردازش تصویر است. که در امر استخراج اطلاعات از سطح مقطع بسیار موثر می باشد دقت و سرعت از خصوصیات بارز این روش است. تاکنون روشهای مطرح شده برای محاسبه فاکتور تجمع این فاکتور را برای الیاف با مقطع دایره ای محاسبه کرد...

A comparison of 4 × 4 multiple-input multiple-output wireless local area network wireless communication characteristics for six different geometrical shapes is investigated. These six shapes include the straight shape corridor with rectangular cross section, the straight shape corridor with arched cross section, the curved shape corridor with rectangular cross section, the curved shape corridor...
