background: the purpose of this study was to evaluate the levels of zinc (zn), copper (cu), iron (fe) and zinc/ cop­per ratio in the serum of patients with cutaneous leishmaniasis in qom province, center of iran. methods: serum levels of zinc and copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an auto analyzer. the study gro...

Novel Fe–28Mn–10Al–C–0.5Nb low-density steel was developed and the room temperature tensile behavior in solid solution state microstructure evolution process during plastic deformation were studied, aiming to clarify dominant mechanisms. The results show that fully austenitic with a low density of 6.63 g/cm3 fairly high stacking fault energy 84 MJ/m2. present exhibited an excellent ultimate str...

Glass is a freezing phase of a deeply supercooled liquid. Despite its simple definition, the origin of glass forming ability (GFA) is still ambiguous, even for binary Cu-Zr alloys. Here, we directly study the stability of the supercooled Cu-Zr liquids where we find that Cu64Zr36 at a supercooled temperature shows deeper undercoolability and longer persistence than other neighbouring composition...

Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...

Evolution of α microstructure on the thermomechanical treated Ti-10Al-1Zr-1Mo-1Nb alloy during annealing was studied. The solution-treated materials were groove-rolled or uniaxially compressed in α+β region and annealed at 1173 K. flow softening behavior crystal rotation platelets revealed an evolution deformation texture. volume fraction equiaxed grains increased annealing. Especially material...

The aim of the present study was to develop and validate the Children's Depression Screener (ChilD-S) for use in pediatric care. In two pediatric samples, children aged 9-12 (N(I) = 200; N(II) = 246) completed an explorative item pool (subsample I) and a revised item pool (subsample II). Diagnostic accuracy of each of the 22 items from the revised pool was evaluated in order to select the best ...
