The evaluation of vegetation covers using conventional methods is difficult over arid areas due to several reasons such as lack of the suitable roads to these regions. Moreover, this task is time-consuming. For these reasons, remote sensing has been considered as an economic alternative for conventional field work. In this study, the feasibility of using IRS images in vegetation cover evaluatio...

Recent theoretical investigations [M. Beneke et al. Phys. Rev. Lett. 83, 1914 (1999)] of two-body hadronic B decays have provided justification, at least to order αs, for the use of the factorization ansatz to evaluate the B decay matrix elements provided the decay meson containing the spectator quark is not heavy. Motivated by this, we present simplified formulae for a wide range of B decays i...
