breeding and cropping cultivars with high weed competitiveness have played an important role in the non-chemical weed management. this experiment was carried out in order to study the effect of nitrogen on weed tolerance and competition indices of five wheat cultivars at the research field of agricultural faculty, university of mohaghegh ardabili, during 2010-2011 growing season. experimental f...

The “phantasmagoria” is a term that originally referred to the ghost lantern shows first staged in France at end of 18th Century by Belgian inventor and entertainer Étienne-Gaspard Robertson. question be addressed this review concerns link between phantasmagoria (defined as ghostly visual entertainment) multisensory sensorium (or sensory overload) fairground even, several other cases, Gesamtkun...

We consider parameters estimation problems involving a set of m physical observations, where an unknown vector of n parameters is defined as the solution of a nonlinear least-squares problem. We assume that the problem is regularized by a quadratic penalty term. When solution techniques based on successive linearization are considered, as in the incremental four-dimensional variational (4D-Var)...

the friction properties of granular materials play an important role in the determination of specifications for designing hoppers, transporting passages, dryers, silos and machines through which grain flows. in this study, the angle of repose and internal friction coefficient were determined for three common wheat varieties (sardary, gaspard and saysoter) at four moisture contents (12, 15, 18, ...
