in order to study of the effect of nitrogen source, operation method and weed control methods on weed biomass, yield and yield components of corn (zea mays l.) an experiment was carried out as split plot factorial based on randomized complete block design (rcbd) with four replications in shahrood university of technology. the treatments included weed control methods at four levels (hand weeding...

OBJECTIVE This paper concerned the perceived suffering/side effects caused by various well-known treatments for personal problems. It looked at whether people understood whether potentially painful treatments that confront negative aversive affect were effective or not. METHOD In total, 106 participants completed a long questionnaire assessing the 'psychological pain' ratings of 30 psychother...

introduction integrated nutrient management involving crop residue/green manures and chemical fertilizer is potential alternative to provide a balanced supply of nutrients, enhance soil quality and thereby sustain higher productivity. the present experiment was undertaken to evaluate the effect of different crop residue management practices and npk levels on yield components and yield of wheat....

In this paper we compute the tree-level four-point scattering amplitude of two dilatini and two axion-dilaton fields in type IIB supergravity in AdS5 × S5. A special feature of this process is that there is an “exotic” channel in which there are no singleparticle poles. Another novelty is that this process involves the exchange of a bulk gravitino. The amplitude is interpreted in terms of N = 4...
