We proposed a novel numerical method for the reliable prediction of decarburization with CO2. In our method, mass, momentum, and energy conservation equations are solved simultaneously, where reactive mass transfer, compressibility, moving interface between gas liquid fully considered. reaction model, we assumed that rate-limiting processes transfer in phase interfacial rate. Our quantitatively...

Fourier transform infra red (FTIR) and energy band gap of potassium lithium borate glasses of different composition have been studied using Fourier FTIR and UV-VIS spectroscopy techniques. The glasses were melted in the alumina crucible in an electric furnace at 1100°C for 30 min until homogenous melt was obtained. The X-ray diffraction analysis was adopted for confirming the amorphous nature o...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...

My proposal is that we should formulate our nomothetic theories in a way that will allow an immediate individual-differences test. I am proposing this because, among other benefits, I believe this approach will make individual differences a crucible in theory construction. The argument I advance is applicable to theory construction in all areas of experimental psychology, but my illustrations c...

The study of a well-preserved crucible fragment from the Middle Kingdom Egyptian fortress in Buhen lower Nubia revealed unexpected presence numerous prills very arsenic- and nickel-rich copper alloy what looks like smelting slag. Based on optical scanning electron microscopy polished section, this paper discusses potential metallurgical process that was carried out type crucible. Strongly reduc...
