abstract the balvard metamorphic assemblage (bma) crops out at the northeastern margin of the southeastern part of the sanandaj-sirjan zone (ssz) in contacting to the dehshir-baft ophiolitic mélange. this location prepared a special situation to resolve some of the complicated tectonic problems of this part of iran. petrology, micro-tectonics and satellite image investigation were carried out ...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...

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...

Abiotic stresses such as salinity, are factors that severely affects agricultural production. To evaluate the effects of salinity on some morphological and physiological traits related to salt tolerance of 22 genotypes of spring rapeseed cultivars in the vegetative growth stage, an experiment was conducted as a split plot form based on Randomized Complete Blocks Design using levels of salinity:...

In order to investigate the effects of irrigation water salinity on root traits and absorption of sodium (Na+) and potassium (K+) by wheat cultivars, a factorial experiment, based on completely randomized design with 3 replications, was ‎conducted under greenhouse conditions. The main factor was 7 wheat genotypes ]Ghods, Marvdasht and Bahar (sensitive to salinity) and Arg, Bam, Sistani and Sing...

  Understanding the reaction form and biochemical response of wheat cultivars about the salinity stress can help to better understand the defense mechanisms and identify the indicators and biomarkers of tolerance screening for salinity stress in this strategic plant and other field crop. For this purpose, biochemical traits related to salinity tolerance of wheat cultivars were evaluated as a f...

why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...

To examine the response of three rapeseed varieties to salinity stress, a pot experiment was conducted in a glasshouse using a factorial experiment based on a randomized complete block design with three replications. Three levels of NaCl (0, 100 and 200 mM NaCl) were imposed as the salinity treatments at root establishment (leaf 4) stage. In this study, sodium (Na+) and potassium (K+) concentra...
