macrophomina phaseolina is an important soil-borne pathogen causing charcoal rot in many important crop plants including sesame, in iran. a total of 60 isolates of m. phaseolina were collected from the main sesame producing regions in ten provinces of iran. the genetic diversity among m. phaseolina populations was estimated using inter-simple sequence repeat (issr), focusing particularly on geo...
in the current study, five different atomistic water models (awms) are implemented, in order to investigate the impact of awms treatment on the water velocity profile and density number. for this purpose, molecular dynamics simulation (mds) of poiseuille flow in a nano-channel is conducted. considered awms are spc/e, tip3p, tip4p, tip4pfq and tip5p. to assessment of the ability of each model in...
Although not very common, forensic investigation related to projectile ricochet on water can be required when undesirable collateral damage occurs. Predicting the ricochet behavior of a projectile is challenging owing to numerous parameters involved: impact velocity, incident angle, projectile stability, angular velocity, etc. Ricochet characteristics of different projectiles (K50 BMG, 0.5-cal ...
conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...
We report the results of a medium-resolution spec-troscopic investigation of the O(f) supergiant HD 192639. Particular attention is paid to the He ii λ 4686 line. This line displays strong profile variability on time scales of a few days, changing from a P-Cygni profile with a double-peaked emission component to a pure blue-shifted emission line. It appears that the variability of most of the a...
Relativistic Turbulence provides an alternative to internal shocks as a mechanism for producing GRBs’ variable light curves with efficient conversion of energy to radiation. In this model the relativistic outflow is broken into small eddies moving relativistically in the outflow’s rest frame. Variability arises because an observer sees an eddy only when its velocity points towards him and only ...
Methods for sizing single chamber tanks to remove different amounts of total suspended solids (TSS) have been available for some time. One method found in the literature uses the concept of upflow velocity (v) or the critical settling velocity of a particle in a tank to determine what size particles will be removed in the tank. The critical settling velocity depends on the relationship between ...
We present a review of novel techniques developed by our research group to improve quantitative assessment of human movement, especially assessments related to symmetric and asymmetric gait patterns. These new methods use motion capture data of the lower limb joints (e.g., joint and body segment angular position and/or velocity, or joint center locations) and include: (1) Regions of Deviation (...
Social judgments about other people are often made based on visual appearance. In this study, we investigated whether visual appearance of an interaction partner influences action coordination in social interactions. In a novel interactive augmented reality setup participants interacted (i.e. carried out a high-five) with a life-sized 3D avatar that was either humanlooking or robot-looking. Imp...
