In this study, 14 advanced chickpea genotypes selected from regional experiments with Adel and Azad, as control cultivars, were cultivated in a randomized complete block design with three replications in eight environments (Gonbad, Gachsaran, Ilam and Khorramabad in three, two, two and one years, respectively) in Iran during 2017-2020 growing seasons. Combined analysis of variance showed that e...
microwave assisted green synthesis of α, ά- bis (substituted- benzylidene) alkanones by the crossed- aldol condensation reaction of substituted aryl aldehydes with ketones in the presence of catalytic amount of nbcl5 in good to excellent yields. this reaction is carried out under solvent-free conditions. the results showed that aldehydes bearing electron–donating substituent's on phenyl-ring fa...
The effect of NO2 on secondary organic aerosol (SOA) formation from ozonolysis of α-pinene, β-pinene, 1-carene, and limonene was investigated using a dark flowthrough reaction chamber. SOA mass yields were calculated for each monoterpene from ozonolysis with varying NO2 concentrations. Kinetics modeling of the first-generation gasphase chemistry suggests that differences in observed aerosol yie...
in the last decades, rice yields in south asian countries grew tremendously in one hand and a noticeable yield fluctuation on the other. the objective of this study was to examine the rice yield distributions, estimate yield risks at country level, and compare risks between five countries namely afghanistan, bangladesh, nepal, sri lanka, and pakistan. anderson darling (ad) test was applied to t...
the purpose of this two-phase, sequential mixed methods study was to find out whether there were any decencies between male and female ma students’ theses regarding the common features of academic writing such as syntactic complexity, means of integrating cited information, and organizing arguments. i chose 10 male written theses and 15 female written theses in tefl and linguistics. in the firs...
