This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

In order to examine the impact of pure and mixed planting on the production of grasses and also the biological control of weeds an experiment was conducted in the research farm of Alashtar city of Lorestan province between the years 1391 and 1392. This experiment within the design of complete random blocks (RCBD) with 6 protections which included 100:0 (rouph pea pure planting) 0:100 (pure plan...

the aim of this paper is to analyze the undamped second order descriptor systems to show the possibility of transform an undamped second order descriptor system to a pure first order descriptor system ,on different ways, while stating some of its benefits. meanwhile we will introduce pure first order systems and undamped second order systems and indicate that under some assumptions every undamp...

in this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (swcnt) is reported. methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. some physical properties of the methanol-water mixture such as r...

in order to evaluate physiological and morphological characteristics and yield of soybean (glycine max l.) cultivars under different planting ratios a field experiment was conducted based on randomized complete block design with four replications at the gaem shahr agricultural research centre of mazandran province, iran, during 2008. two soybean cultivars (032 and sari) were planted in row inte...
