a synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language

terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...

The Spark Spectrum of Neon.

35 kv. as compared to 55 kv. for the arc discharge on an ordinary day. The experiment clearly showed that corona current flow in an atmosphere of high humidity is greatly reduced, and that spark discharges at relatively low voltages are apt to occur. The explanation of this phenomenon very likely is to be found in the reduction of the mobility of negative ions in air of high humidity, although ...

Two-photon transitions in primordial hydrogen recombination

The subject of cosmological hydrogen recombination has received much attention recently because of its importance to predictions for and cosmological constraints from cosmic microwave background observations. While the central role of the two-photon decay 2s! 1s has been recognized for many decades, high-precision calculations require us to consider two-photon decays from the higher states ns, ...
