T-tubes are generally safe artificial airways used to stent and maintain the laryngotracheal airway in patients with stenosis or after laryngotracheal reconstruction. T-tube related airway complications are uncommon but potentially life-threatening. T-tube aspiration is rarely reported in the literature and may occur after coughing episodes and deep inspiration. Two cases of T-tube aspiration i...

Migration of a biliary stent from the intrahepatic biliary tract into the duodenum is a known complication after endoscopic retrograde cholangiopancreatography (ERCP). The procedure to remove these stents has also been reported in the literature. We report on a case of T-tube migration into the duodenum, and describe the cause of migration and the technique to remove the migrated T-tube. This h...

From the study of the material collected during the Polychaete Workshop held in Lizard Island (Great Barrier Reef, Australia) in August 2013, six species belonging to the genus Armandia (Polychaeta, Opheliidae) are newly described. Armandia bifida n. sp. is characterised by the bifid shape of the prechaetal lobe in CH1-CH3, A. dolio n. sp. by the barrel-shaped anal (=pygidial) tube (=funnel), A...

A44yearoldwomanwas referredfromanotherhospital with a retained T-tube, She had an open cholecystectomy during which common bile duct was divided, This was recognised and an end-to-end anastomosis was performed about a number 12 T-tube, Postoperative recovery was uneventful and an early T-tube cholangiogram indicated satisfactory alignment without significant leak out of the ductal system. T tub...

This study is focused on the removal of leachable lead present in CRT (cathode ray tube) glass employing different chelating agents, NTA (nitrilotriacetic acid) and ATMP (amino trimetilen phosphonic acid), and then on the evaluation of their extractive capability. The operating conditions are the following: T=80°C, t=1h, pH=10, solid/liquid weight ratio=1/10, reagent concentration= 0.1 M. After...

Rubber based forming process is a versatile metal fabrication process used in commercial aerospace, automotive and defence applications. It is well suited for prototyping and production of small quantities of sheet metal parts. Rubber based forming employs a rubber pad contained in the rigid chamber or flexible diaphragm as one tool half, requiring only one solid half to form a part to final sh...

Abstract Impact hydroforming (IHF), as a novel sheet metal forming technology with the advantages of high strain rate and flexible liquid loading, is highly suitable for efficiently manufacturing aluminum complex-shaped parts. In this paper, deformation characteristics complex parts under IHF are systematically investigated. The mechanical properties 2024 alloy wide range rates (10 ?3 s ?1 –3.3...
