Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...

Introduction: Dental turbine chamber is a suitable reservoir for living microorganisms, so chamber sterilization is necessary for reducing cross contamination risk. On the other hand, in non-vacuum autoclaves, steam penetration into turbine chamber is doubtful, while they are still in use in dental clinics. In this study, performance of small non-vacuum autoclave in turbine chamber sterilizatio...

Abstract To increase productivity when joining galvanised sheet metal, metal inert gas (MIG) and tungsten (TIG) arc brazing are combined in a hybrid process. This coupling of two processes increases speed reduces weld reinforcement the tendency to spatter. Because arcs 6 mm apart, they influence each other. Therefore, blowing action is major challenge brazing. A current modulation optimal relat...

Ag is used as a useful alloying element in brazing filler metals. It clear that the addition of has positive effect on melting temperature, wettability, conductivity and mechanical property For this reason, although very expensive, it still widely many research production. In study, was focused obtaining both high strength cost-effective joints by using metals containing different levels Ag. Me...
