We compute the strong coupling constant G B B (G D D), where B (D) is the 0 + P?wave b q (c q) state, by QCD sum rules and by light-cone sum rules. The two methods give compatible results in the limit m Q ! 1, with a rather large value of the coupling constant. We apply the results to the calculation of the hadronic widths of the positive parity B and D states and to the chiral loop contributio...

The use of cloud-base height data obtained from a groundbased microwave radiometer in the estimation of total cloud amount has been studied by Chan and Li (2009). The present paper extends the study by considering the performance of the total cloud amount estimation algorithm in different seasons and different years. It is found that the algorithm works generally well in different periods by co...

A detailed safety analysis was performed for the inertial confinement fusion reactor OSIRIS. The radioactivity induced in the carbon fabric chamber concrete shield and Flibe breeder is very low allowing for their disposal at the end of the reactor life as Class A low level waste (LLW). The biological dose rate after shutdown behind the reactor biological shield shield is very low (0.11 μ rem/hr...

The fall of the caliphate proclaimed in June 2014 by Abu Bakr al Baghdadi from Great Mosque Mosul has brought with it return to Europe thousands foreign terrorist fighters, many them accompanied women and children. And, this sense, Spain not been an exception. There is no doubt that, within subjects who have returned other countries West, there a significant number do so considering their exper...

We present a four-probe setup for measuring temperature of Joule-heated silicon in two independent ways from the same voltage measurement: method using thermal dependence resistivity and based on measured sheet power density. The methods are compared to optical measurements made by fitting gray-body model onto data commercial spectrometer. conducted 890 K 1540 K, they converge at temperatures a...

dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. this study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such diseases.saponins were extracted from bauhinia purpurea, madhuca longifolia, celastrus paniculatus and sem...
