A60-year-old woman was hospitalized for oliguria with bilateral impediment of both renal pelvises. Bilateral nephrostomies were necessary. Twelve months earlier, two titanium stents (Engineers & Doctors) had been implanted in the distal parts of both ureters because of diffuse ureteral stenosis after irradiation therapy for cervical carcinoma 17 years earlier. At admission, retrograde pyelograp...

Aim: To estimate and compare the frictional forces engendered by three types of aestheticselfligating brackets with two straight wire alloys. Materials: The study comprised of a total of 90 brackets, of which 30 passive (Damon clear 2),30 active(GAC In-Ovation C) and 30 interactive (Empower clear) orthodontic brackets with a slot size of .022X.028 MBT prescription in combination with stainless ...

Earlier studies have shown that it is possible to successfully obtain Ti6Al4V-Cu alloys with various copper concentrations using the double-wire electron beam additive manufacturing. Obtaining these of a practical interest for creating titanium-base composite material reduced risk spontaneous combustion, which could be used in friction units at elevated temperatures. This article presents study...

The local electrochemical properties of galvanic corrosion for three coupled metals in a desalination plant were investigated with three wire-beam electrodes as wire sensors: aluminum brass (HAl77-2), titanium (TA2), and 316L stainless steel (316L SS). These electrodes were used with artificial seawater at different temperatures. The potential and current-density distributions of the three-meta...

Twin-wire plasma arc additive manufacturing (TW-PAAM) is an innovative process for titanium aluminide manufacture which low in equipment cost and high efficiency. However, as situ alloying process, the composition homogeneity typically a source of concern. The present work investigates this subject by observing element input mode at various welding wire positions with high-speed camera system p...

Abstract Hot-wire laser welding is additive manufacturing (AM) technique that allows for the direct creation of complicated objects by melting layers wire. This process characterized use hot-wire process, unification with (LW) in AM process. The empirical investigation employing a on titanium alloy (grade 2) workpiece presented this research. There are three parameters namely wire current, spee...

OBJECTIVE The purpose of this study was to compare the outcome of wire osteosynthesis with bone plating in the management of zygomatic complex (ZMC) fractures. The rationale was to enable the oral and maxillofacial surgeon to select either of the treatment procedure with confidence. METHODS In this quasi experimental study, Sixty five patients of ZMC fractures were randomly allocated in group...

OBJECTIVE The objective this work was to assess the friction coefficient between brackets and wires of different materials under conditions simulating the oral environment. MATERIAL AND METHODS Stainless steel (SS) and titanium-molybdenum alloy (TMA) wires of 0.019x0.025-in diameter (American Orthodontics) and polycarbonate bracket (American Orthodontics), ceramic bracket (American Orthodonti...
