Generated by zinc hydrometallurgical production and containing several toxic species, jarosite has been little used or beneficiated to date. Utilization of can save mining resources producing valuable products, reduce potential hazards from disposal. To avoid high energy consumption as in the roasting steps current process, hydrometallurgy various an original process aimed at zinc-iron alloys i...

The localized corrosion behavior of precipitation-hardened UNS N07718 was investigated by immersion tests in 6 wt% FeCl<sub>3</sub> + 1.0 HCl and the use electrochemical techniques a simulating solution diluted-sour environment 25 NaCl 0.5 CH<sub>3</sub>COOH. Ti carbides Nb-Mo with 1-10 µm size were distributed alloy. After at temperature higher than 45<sup>o</s...

The objective for this study was to investigate whether the postural control adaptation during galvanic stimulation of the vestibular nerve were similar to that found during vibration stimulation to the calf muscles. A method for adaptation analysis was used to analyze the evoked changes of posture, stimulus responses and the motion dynamics. The adaptive adjustments of postural control were si...

We investigated film thickness effects of sulfuric acid anodized aluminum when galvanically coupled with carbon fiber reinforced plastic（CFRP）. The CFRP was electrically to alloys 1050, 5052, 6061, and 7075 in 3.5 wt.% NaCl solution at 35 ℃. Galvanic current passing from the 1050 6061 decreased as anodic oxide thickened. For galvanic between 5052 CFRP, elapsed time until corrosion density value...

In this paper, a novel step-up converter is proposed, which has the particular features of single semiconductor switch, ultra-high conversion ratio, galvanic isolation, and easy control. Therefore, the proposed converter is suitable for the applications of fuel-cell power system. Coupled inductors and switched capacitors are incorporated in the converter to obtain an ultra-high voltage ratio th...

Background and aims. This study compared the galvanic corrosion of orthodontic wires and brackets from various manufacturers following exposure to a fluoride mouthwash. Materials and methods. This study was conducted on 24 lower central incisor 0.022" Roth brackets of four different commercially available brands (Dentaurum, American Orthodontics, ORJ, Shinye). These brackets along with stainles...

Magnesium (Mg) has drawn increasing attention as a tissue engineering material. However, there have been very few studies of laser-melted Mg-Zn alloys. In this study, four binary Mg-xZn (x = 2, 4, 6 and 8 wt. %) alloys were fabricated by laser melting. The influence of zinc (Zn) content and technique on the degradation behavior and mechanical properties of Mg were discussed. Results revealed th...

aim and background: emotion focused couple therapy is one of the methods that has focused on the negative cycles of interaction caused from deep emotional vulnerability. the purpose of this study was to determine the effect of emotionally focused couple therapy on reducing the damage caused by marital infidelity. methods and materials: the statistical sample included 30 couples that were select...

The intra-body communication is an emerging wireless communication technology. It gives rise to slight wound without any infection, makes relevant devices positioned more easily and plays an important role in realtime monitoring of human body. According to coupling modes of electrodes, the intra-body communication is classified into two types, the capacitive and the galvanic coupling intra-body...
