The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...

This study aimed to investigate if a thermal barrier coating (TBC) affected the energy efficiency of 3D printers. In accordance with this purpose, used TBC technique is clearly explained and adapted nozzle in simulation environment. Brass, copper, hardened steel were selected be materials for nozzles. The reason usage method that are made low conductivity, which reduces conductivity losses. Ytt...

insulator, and this in turn carries a 1-, in. brass rod, Q, fixed and sealed in position by a screw cap, R, and 0-ring gasket. The tungsten-anode wire, S (0-1 mm. diameter), is sheathed by a copper tube, T (diameter i16in.) to which it is soldered at its upper end. This is held in the rod, Q, by a small grubscrew. By this means the whole anode assembly is easily taken apart for cleaning and cha...

Two experimental groups of abutments were prepared: (1) 4.3-mm platform width implant abutment with a 6.5-mm height (control), and (2) a 4.3-mm platform width implant abutment with a 5.5-mm height (shorter). Each abutment had 5 zirconia copings (custom designed) fabricated through a 3-dimensional computer-assisted design (3-D CAD) process by scanning an identical wax pattern. The zirconia copin...

aged 26, a brass moulder, was knocked down by a tram car and run over. On admission to the hospital on June 20th, 1884, immediately after the accident,
