CDF recently measured the quantity σ(B + c ) σ(B+) BR(B c →J/ψlν) BR(B+→J/ψK+) , from which we determine the ratio σ(B + c ) σ(b̄) to be (2.08 −0.95) × 10−3. If we interpret this ratio as a fragmentation probability, we show that this ratio is consistent with the prediction by perturbative QCD Bc fragmentation function of Braaten, Cheung, and Yuan. We also estimate the parameter mc (charm quark ...

there has been considerable inconsistency regarding the potential relationship between dyslipidemia and bone metabolism. the inflammatory stimulation through the receptor activator of the nuclear factor kappa-b ligand (rankl)/ receptor activator of the nuclear factor kappa-b (rank)/ osteoprotegerin (opg) pathway could be the infrastructural mechanism for hypercholesterolemia-induced bone loss. ...

in order to study the effect of different water potential on anethum graveolens l. an experiment was conducted. this study was carried out based on completely randomized design with three replications. in this experiment, morpho-physiological characteristics were assessed under hydroponic. stress was established with peg 6000, and drought potentials were: 0 (control), -1.5, -2, -2.5 and -3 bar....
