maw?q?t and recently found rules

having briefly been reviewed the historical process of changing the formulae for determining the times of islamic prayers, two newly found formulae and a new rule for establishing the times of prayers would be discussed. these matters have been exploited from four texts, still preserved as manuscript: (1) siyyid ¾?y? al-d?n sh?shtar?’s ¼ad b?b dar macrifa al-a½??rl?b, (2) b?r?n?’s ’ist?c?b f? c...

Photobiological safety of the recently introduced energy efficient household lamps.

OBJECTIVES Nowadays more and more newly introduced light sources (tungsten-halogen, compact fluorescent (CFL) and light-emitting diode (LED) lamps) are used in households. It is important to know whether their radiation poses any possible risk for human health or not. These light sources emit optical radiation not solely in the visible spectrum. Other bands emitted by these sources, i.e., ultra...

The Trapped Heavy Noble Gases in Recently Found Martian Meteorites

Introduction: Noble gases in Martian meteorites are an important source of our knowledge of composition and evolution of the volatile inventory of Mars [1]. Ancient (ALH 84001), fractionated (nakhlites), and recent atmosphere (shock-produced glass in shergottite EETA 79001) as well as at least one component originating from the interior (Chassigny) have been identified based on analyses of the ...

Microwave observation of the "recently found" polar OCS dimer.

Recently Afshari et al. reported on the detection of a new infrared band which was assigned to the "long-anticipated polar isomer of the OCS dimer" [J. Chem. Phys. 126, 071102 (2007)]. The authors report here the microwave confirmation of their results. The lowest energy, nonpolar isomer of (OCS)2 has long been known from IR spectroscopy, while the polar form has only been deduced from qualitat...
