In order to quantifying emergence pattern of rapeseed weeds, this experiment was conducted in 40 plots (40 quadrates at Agricultural Sciences and Natural Resources University of Khuzestan, and 30 fields of Bavi (30 quadrates), Ahvaz, Iran, in 2016-2017 growing seasons was monitored, counted and recorded weekly. Three different emergence pattern of nine weed species were identified, Prickly lett...

there are some computer programs to calculate germination related traits such as germin which have using problems. the aim of this work was to adjust germin for calculating germination related traits. seed aging effects on the seedling emergence was modeled using the optimized germin. this study was conducted based on completely randomized design in a factorial combination of five seeds aging t...

a pot experiment laid out in factorial arranged in completely randomized design with three replications was implemented to evaluate the effects of seed priming in ameliorating salinity stress in sesame (sesamum indicam l.) during seedling development and the early vegetative growth. factors included five priming treatments : control (non priming) , hydropriming, halopriming with nacl, kcl , cac...

The urban heat island (UHI) phenomenon is a harmful environmental problem in urban areas affecting both climatic and ecological processes. This paper aims to highlight and monitor the spatial distribution of Surface UHI (SUHI) in the Casablanca region, Morocco, using remote sensing data. To achieve this goal, a time series of Landsat TM/ETM+/OLI-TIRS images was acquired from 1984 to 2016 and an...

We consider a quantum universe composed of small system $S$ and large environment. It has been demonstrated that, for the vast majority randomly chosen wave functions satisfying total energy constraint, reduced density matrix is given by canonical statistical distribution. Here, through Page-Wootters mechanism, we show that time nonequilibrium dynamics can emerge as consequence entanglement bet...
