in order to investigating theeffects of crop rotation and applying of herbicides on weed distribution in irrigated wheat fields of kermanshah province, this study was performed during 2011-2012. multivariate analysis (rda) revealed the significant relationship between composition and species frequency and exerted management techniques. the first and second features of rda indicated 57%, 74.9...
The present research investigates the torsional aeroelasticity of the blade of an H-type vertical axis wind turbine subject to stall and post-stall conditions in various Reynolds regimes, which is experienced by the blade in a full revolution. In order to simulate the aerodynamics, a new model based on a combination of the Double Multi Streamtubes (DMST) model and the nonlinear multi-criteria C...
We directly compared recognition for faces following 0 degrees-75 degrees viewpoint rotation about the yaw, pitch, and roll axes. The aim was to determine the extent to which configural and featural information supported face recognition following rotations about each of these axes. Experiment 1 showed that performance on a sequential-matching task was viewpoint-dependent for all three types of...
abstract in order to evaluate the effects of rice conventional herbicides on rotational second crops (lettuce, cress, clover, canola and radish), soil microbial biomass and diversity, a field and glasshouse experiments were conducted in mazandaran province and research glasshouse of ferdowsi university of mashhad, respectively. five experiments were carried out for 5 second crop separately with...
The most important features and phenomena of the deformation behavior of rockfills are stress-dependent stiffness, hardening and dilative (or contractive) behaviors, as well as breakage, rotation and redistribution of particle size. An elasto-plastic constitutive model has been suggested by Vermeer and de Borst to simulate the shear behavior of soils, concretes and rocks. This research has trie...
Introduction: The present study aimed to investigate the psychometricproperties of Grasha-Riechmann Student Learning Styles Scale.Method: The participants included 1039 students (421 students in human and 618 students in technical sciences), selected through the stratified sampling method from Tehran University. They answered the Grasha-Riechmann student learning style scale and the data was an...
