data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Photosynthetic bacteria (PSB) have been extensively used in agriculture to promote plant growth and to improve crop quality. Their potential application in plant disease management, however, is largely overlooked. In this study, the PSB strain Rhodopseudomonas palustris GJ-22 was investigated for its ability to induce resistance against a plant virus while promoting plant growth. In the field, ...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
this study aimed to investigate the effects of listening strategy training on iranian efl learners listening comprehension and use of such strategies. this work, employing an experimental methodology, was conducted among 60 adult efl learners from a language institute in isfahan, iran, as participants. the participants, who were selected based on the results of a placement test, were assigned t...
Two strains of Proteus isolated from tea plantation soil were tested for their ability to colonise the roots of gram (Cicer arietinum), bean (Phaseolus radiatus) and mung (Phaseolus mungo) using a gnotobiotic system. Seeds bacterized with the two strains grew faster and showed significant increase in root and shoot enlargement of the plants tested. The bioactive fractions obtained from the cult...
Enterobacter sp. strain R4-368 is one of the few characterized Jatropha endophytic diazotrophic bacteria and was isolated from surface-sterilized roots. This bacterium shows strong growth-promoting effects, being able to increase plant biomass and seed yields. Enterobacter sp. R4-368 is the second fully sequenced diazotrophic Enterobacter species. The sequence information shall facilitate the e...
A total of twenty five endophytic bacteria were isolated from green gram Vigna radiata (L.) plant. Four isolates which have shown better response for plant growth promoting effects on green gram plants were used as Plant Growth Promoting Bacteria (PGPB) in this study. It has been detected that up to 40% of the genomic 16S rRNA of isolated bacteria belongs to the Azotobacter genus. The result fo...
Rhizosphere microorganisms are a heterogenous group of bacteria, including plant growth promoting bacteria, which can improve extent or quality of plant growth direct and indirect. Generally large array of bacteria, including species of Pseudomonas, Azospirillum, Azotobacter, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus and Serratia have been reported to enhance p...
