if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
A field experiment was conducted to evaluate the competition of soybean intercropped with niger in different planting ratios using randomized complete block design with four replications at Sari agricultural sciences and natural resources university in 2018 and 2019. The intercropping ratios were 0:100, 25:75, 50:50, 75:25, and 100:0 (soybean:niger, respectively) using the replacement series. R...
Cereal-legume intercropping practices improve the sustainability of production and productivity. However, identification suitable crop plant density component crops is essential. A field experiment was conducted to evaluate varietal effects soybean intercropped with maize effect densities varieties on yield components associated productivity system at Wama-Hagelo District, western Ethiopia duri...
introduction weed infestation causes an extremely reduction of crops yield. on the other hand, increasing the diversity of crops in agro-ecosystems will change the biomass distribution of weeds community, thereby reducing the number and density of different weed species. weed management in the past few decades has been in conflict with ecological principles and sustainability of the production ...
Intercropping is a breakthrough in land-use optimization. This work aimed to study the effects of intercropping patterns on growth, yield, root morphological characteristics, and interspecific competition maize soybean, as well provide reference for development soybean Northwest China. Three different cropping were designed: monocropping maize, maize-soybean intercropping. Agronomic traits, ind...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
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...
in order to study the effect of inter cropping (blend) of three sesame (sesamum indicum l.) cultivars (sabzevar, kashmar, kalat) an experiment was conducted as a factorial based on complete randomized block desing with 3 replications at research farm ferdowsi university in 2009. the experimental treatments were obtained: sole cultivation of sabzevar, kalat, kashmar, and their mixed crops (1. sa...
abstract this study evaluated and compared medical terminology and english for the students of medicine (ii) as two representatives of the textbooks available on the iranian market for teaching english to the students of medicine. this research was performed on the basis of a teacher’s and a number of students’ attitudes and the students’ needs analysis for two reasons: first, to investigate...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
