Seventy-eight supracondylar fractures of the humerus in children were reviewed to compare four kinds of treatment: closed reduction and immobilization in a cast or splint, overhead skeletal traction, side-arm skeletal traction, and Dunlop's skin traction. The skeletal traction device usually used was a winged screw of our own design. The arms treated in overhead traction had significantly less ...
the arithmetic mean roughness, ra, values were determined by scanning electron microscopic technique of different core models (furazolidone, nitrofurantoin and acetyl salicylic acid), coated by hpmc film forming solution containing 10 wt% of various molecular weight pegs. the results showed that both plasticizer molecular weight and core surface free energy could have a significant influence on...
effects of some thermo-physical parameters on free convective heat and mass transfer over a vertical stretching surface at lowest level of heat energy in the presence of suction is investigated. the viscosity of the fluid is assumed to vary as a linear function of temperature and thermal conductivity is assumed constant. a similarity transformation is applied to reduce the governing equations i...
in this article, finite difference method (fdm) is used to study the size-dependent free vibration characteristics of rectangular nanoplates considering the surface stress effects. to include the surface effects in the equations, gurtin-murdoch continuum elasticity approach has been employed. the effects of surface properties including the surface elasticity, surface residual stress and surface...
1 With guided-wave approaches becoming prevalent for structural health monitoring, the need has arisen for more effective models employing these methods using piezoelectric transducers. This paper describes an analytical formulation to couple transducer dynamics with axisymmetric guided-wave excitation models for isotropic plates. The finite-dimensional piezo-actuator dynamics are modeled using...
مقدمه : استعمال سیگار و مواد مخدر از جمله معضلات رایج بهداشتی محسوب می شوند. نه تنها استعمال سیگار، بلکه مواجه با دود آنها نیز عواقب زیادی را برای انسان ایجاد می نماید. در معرض دود سیگار بودن نیز خطر ابتلا به سرطان و بیماری های قلبی و عروقی را افزایش می دهد. یکی از عوامل مطرح شده در مورد مصرف سیگار اختلال در روند التیام زخم می باشد. بر همین اساس بر آن شدیم که به بررسی اثر مصرف سیگار بر روی باز ...
Focal adhesions (FAs) are integrin-based transmembrane assemblies that connect a cell to its extracellular matrix (ECM). They are mechanosensors through which cells exert actin cytoskeleton-mediated traction forces to sense the ECM stiffness. Interestingly, FAs themselves are dynamic structures that adapt their growth in response to mechanical force. It is unclear how the cell manages the plast...
