the effective parameters of (5, 0) and (5, 5) single-wall carbon nanotubes during the interaction with carbon dioxide as sensors are determined. the interaction of carbon dioxide  molecules with internal and external walls of the nanotubes is studied using gaussian 03 coding by density functional theory (dft) at the b3lyp/6-311g level of theory. co2 rotation around tube axles vertically and par...

background: the treatment of open tibial fractures is still an orthopaedic challenge and full of complications. in many cases the use of external fixator that has been known as a non-:union: machine is obligatory with a high incidence of pin track infection and other complications. the aim of this study was to compare the use of external fixation as a definite method for treatment of open tibia...

The aim of this communication is to show how, depending on the type of the control law (static or dynamic), some fine structures (internal or input-output ones) have to be known precisely, since they completely characterize the solvability of control problems like decoupling, disturbance decoupling or model matching, . . . . These structures mainly describe zeros (finite and at infinity) and ke...

Various studies have shown that the external focus of attention is better than the internal focus of attention. But, so far no study has been investigated the level of electrical activity of the rectus abdominus muscle as a trunk stabilizer muscle. Therefore, the purpose of this study was to investigate the effect of focus of attention on electromyography activity of the rectus abdominus muscle...

Introduction: Cleaner productions in textile industry is achieved by reducing water and chemicals’ consumption, saving energy, reducing production of air pollution and solid wastes, reducing toxicity and noise pollution through many solutions. The purpose of the present research was to apply Strengths, Weaknesses, Opportunities, Threats (SWOT) and Quality Systems Planning Matrix (QSPM) te...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : distraction osteogenesis is an established option for reconstruction of amputated fingers. in contrast to the primary method of distraction osteogenesis, using kirschner wire (k-wire) as an internal fixator is not common today. this study was conducted to evaluate distraction osteogenesis with and without k-wi...
