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...

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...

INTRODUCTION A private network that carries sensitive data between local computers requires proper security measures to protect the privacy and integrity of the traffic. When such a network is connected to other networks, or when telephone access is allowed into that network, the remote terminals, phone lines, and other connections become extensions to that private network and must be secured a...

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...

background: tissue expanders are devices which are used to create enough skin to form suitable flap in restoration of great skin deficiencies which are not modified initially. the current study aimed at investigating the patients’ satisfaction and the complications such as rupture, hematoma, wound infection, seroma, leakage, chronic pain, and expander expose of internal (implanted under the ski...

Background. Endotoxin initiates osteoclastic activity resulting in bone loss. Endotoxin leakage through implant abutment connections negatively influences peri-implant bone levels. Objectives. (i) To determine if endotoxin can traverse different implant-abutment connection (IAC) designs; (ii) to quantify the amount of endotoxins traversing the IAC; (iii) to compare the in vitro comportments of ...

OBJECTIVES This study was undertaken to characterize the mechanical response of bare (as-received) and single-layer ceramized zirconia abutments with both internal and external connections that have been developed to enhanced aesthetic restorations. MATERIAL AND METHODS Sixteen zirconia implant abutments (ZiReal Post®, Biomet 3i, USA) with internal and external connections have been analyzed....

Heat EXchangers (HEX) that are used in City Gate Station (CGS) systems are modeled numerically to recover the exhaust waste heat. It was tried to find the best viscous model to obtain results in accordance with experimental results and to change the heat exchanger design. This HEX is used for recovering heat from exhaust flue gas with a mixture of 40% water and 60% ethylene glycol as the coolin...
