In order to evaluate the effects of plastic bed mulch and sowing date on early maturity, growth and yield of Ahvazi-Okra and obtaining the highest production during the peak price period, an experiment was executed in Agricultural and Natural Resources Research Center of Khuzestan. The experiment was laid out as split plot design in RCBD with four replications. Four sowing dates including Feb. ...
We discuss the effects of the δ2 and Lubkin acceleration methods on the partial sums of Fourier Series. We construct continuous, even Hölder continuous functions, for which these acceleration methods fail to give convergence. The constructed functions include some interesting trigonometric series whose properties were investigated by Hardy and Littlewood.
We developed a cohort model to evaluate the expected public health impact of accelerated regimens for immunization against rotavirus gastroenteritis (RVGE). Alternative strategies for vaccination with the pentavalent human-bovine reassortant vaccine, Rotateq(®) (RV5, Merck) and the oral live attenuated human rotavirus vaccine, Rotarix(®) (RV1, GlaxoSmithKline Vaccines) were considered, includin...
Experiments were conducted in a previously described crossed electron/molecular beam instrument1. In brief, an electron beam (~110 meV resolution) is generated with a trochoidal electron monochromator and crossed with an effusive beam of HFeCo3(CO)12 supplied through a capillary tube by sublimation at 348-353 K. The electron energy is scanned by ramping the acceleration voltage of the monochrom...
Hard X-ray sources from femtosecond (fs) laser-produced plasmas, including the betatron X-rays from laser wakefield-accelerated electrons, have compact sizes, fs pulse duration and fs pump-probe capability, making it promising for wide use in material and biological sciences. Currently the main problem with such betatron X-ray sources is the limited average flux even with ultra-intense laser pu...
A new method to admit large Courant numbers in the numerical simulation of multiphase flow is presented. The governing equations are discretized in time using an adaptive -method. However, the use of implicit discretizations does not guarantee convergence of the nonlinear solver for large Courant numbers. In this work, a double-fixed point iteration method with backtracking is presented, which ...
We describe the first demonstration of plasma mirrors made using freely suspended, ultra-thin films formed dynamically and in-situ. We also present novel particle-in-cell simulations that for the first time incorporate multiphoton ionization and dielectric models that are necessary for describing plasma mirrors. Dielectric plasma mirrors are a crucial component for high intensity laser applicat...
