in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

  To evaluate the effect of plant density on yield and quantitative characteristics of two greenhouse cucumber cultivars, this experiment was planned as factorial, based on completely randomized blocks design with three replications, during two years in the greenhouse of Jiroft Agricultural Research Center, Jiroft, Iran. The experimental factors were width of planting strip (15, 30 and 45 cm), ...

To evaluate the effects of row spacing and plant density on yield and yield components of sweet corn, variety KSC403, an experiment was conducted in Research Farm of Isfahan University of Technology, Isfahan, Iran, in 2007, as randomized complete block design with a split-plot layout and three replications. The main plots were allocated to two row spacing (60 and 75 cm) and the sub-plots accomm...

In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...

A greenhouse experiment was conducted in order to evaluate the influence of different nitrogen (N) and zinc (Zn) levels on yield, yield components, seed quality and N and Zn contents of two cultivars of rapeseed (Brassica napus L.). In this study, two cultivars of rapeseed (Talayeh and Opera), three N levels (100, 200 and 300 mg/kg) and three Zn levels (0, 5 and 10 mg/kg) with three replication...
