introduction: laser tissue soldering using albumin and indocyanine green dye (icg) is an effective technique utilized in various surgical procedures. the purpose of this study was to perform laser soldering of rat skin under a feedback control system and compare the results with those obtained using standard sutures. material and methods: skin incisions were made over eight rats’ dorsa, which w...
Polymer-based nanocomposites due to their advantages such as corrosion resistance,adequate mechanical properties and low cost are widely used in modern technologies. The increasing application of these nanocomposites, and hence their welding seems unavoidable. In this paper, a novel hottool in friction stir welding process is used for butt welding nanocomposite plates of 5 mm thick containing p...
Glycyrrhiza glabra extract is gaining increasing acceptance as a folk remedy for treatment of wound. We studied the effect of its extract on wound tensile strength in albino rats. 20 male albino rats had a linear 3 cm incision made over skin of back. The animals were randomly divided into two experimental groups, as control and treatment. Animals of control group received topical cold cream onc...
in this research formability behavior and texture of st14 low carbon steels produced by foolad mobarakeh plant for deep drawing application had been studied. plate textures were characterized by x-ray diffraction technique. to evaluate formability behavior one dimensional tensile test was carried out and related parameters were recognized. moreover eriksson experiment and spherical pattern prin...
Polyamide 6 / nitrile butadiene rubber / nanoclay (PA6/NBR/clay) nanocomposite has gathered wide acceptance in industry. Laser welding, as a fabrication method, is applied to welding of polymer nanocomposites. In this study, the input parameters (clay (Closite 30B) content, laser power, scan velocity and stand-off-distance) are varied to achieve the best responses (tensile strength of welds). R...
The dynamic characterization of concrete is fundamental to understand the material behavior in case of heavy earthquakes and dynamic events. The implementation of material constitutive law is of capital importance for the numerical simulation of the dynamic processes as those caused by earthquakes. Splitting tensile concrete specimens were tested at strain rates of 10(-7) s(-1) to 10(-4) s(-1) ...
The mechanical properties of bulk metallic glasses (BMGs) and their composites have been under intense investigation for many years, owing to their unique combination of high strength and elastic limit. However, because of their highly localized deformation mechanism, BMGs are typically considered to be brittle materials and are not suitable for structural applications. Recently, highly-toughen...

the spot welding is widely used for joining thin sheets in different industries; such as automotive industry. this method of welding is very easy to automate and maintain. in this study, the effect of nugget diameter on the tensile-shear strength of the spot welding joints was investigated. the specimens were manufactured from aisi 1008 hr sheets with 1.0 mm thickness. the eight different elect...
tendons are frequently targets of injury in sports and work. whether nonsteroidal anti-inflammatory drugs (nsaids) have beneficial effects on tendon healing is still a matter of debate. this study was conducted to evaluate effects of flunixin meglumine (fm) on tendon healing after experimentally induced acute trauma. twenty eight adult male new zealand white rabbits were subjected to complete t...
