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...

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...
