Two-spotted spider mite) Tetranychus urticae) is one of the most important pests of common bean (Phaseolus vulgaris) in Iran. Common bean seedlings are susceptible to the mite and greenhouse is a suitable environment for two spotted spider mite reproduction. Accordingly, to evaluate the mite resistance, 19 common bean genotypes were planted in a completely randomized design arrangement with t...
Nowadays, spraying and foliar feeding represent one of the most effective techniques of applying essential nutrient elements to crops and to optimize the application of fertilizers in agriculture. In this research, effect of foliar application of different concentrations of ammonium sulfate on quantity and quality traits of cucumber under greenhouse conditions was investigated. The research was...
a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
The use of evolutionary algorithms for calculation of the optimal control of the states of a greenhouse system will be presented. The integrated model employed (greenhouse climate, crop growth, outside weather conditions and control equipment) predicts temperature, air humidity and CO2 concentration in a time interval of 15-60 minutes (short time-scale model). The paper presents the optimizatio...
mprovement of N2 fixation might be an effective strategy in peanut breeding for high yield under drought stress conditions. However, under water limited conditions peanut varieties having high water-use efficiency (WUE) are favorable. A pot experiment was conducted under greenhouse conditions at Khon Kaen University, Thailand during December 2002 to May 2003, and repeated during June 2003 t...
