BACKGROUND This study aimed to assess the clinical short-term results of a primary closure following laparoscopic common bile duct exploration (LCBDE) combined with intraoperative choledochoscopy and D-J tube drainage for choledocholithiasis treatment. MATERIAL AND METHODS Twenty-five patients (14 women and 11 men) who underwent LCBDE with primary duct closure and D-J tube drainage for choledoc...

Light-weight and high strength alloys such as Al-Mg alloys are used in order to reduce the weight of industrial components. However these materials should be formed at elevated temperatures due to their poor formability at room temperature. Hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. Recent investigation on tube hydroforming showed positiv...

This paper describe the high-voltage pulsed discharge generated in water with different types of bubbling gases as well as no gas in a reactor with a point-mesh electrode configuration. The pulsed discharges are a promising technique in environmental remediation to treatment of wastewater. Acid orange 7organic dye solution was treated as a common wastewater sample to elucidate chemical efficien...

In this study, hot metal gas forming process of AA6063aluminumtubeis studied with a focus on heat transfer of both fluid and solid phases numerically. An experimental study is simultaneously conducted to validate the numerical method. Some of the most important outputs of the present study, are velocity distribution of fluid inside the tube as well as the fluid in the gap between tube and matri...
