abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...

Identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. In order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in Minoodasht region in Golestan province (north of Iran) were evaluated. Traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...

Identification of rice germplasm is necessary for aplication of genetic resources for rice breeding. In this purpose 30 rice genotypes evaluated based on important agronomic traits and RAPD markers. The maximum variation coefficient belonged to unfilled grain (76.6%) and minimum to panicle iength (18.46%). results of Euclidean similarity coefficient and UPGMA algorithm indicated 3 distanced gro...

To study grain quality traits and their relationships with high molecular weight (HMW) and low moleculor weight (LMW) glutenin subunits, 104 durum wheat genotypes were used. Six grain quality characteristics comprising wet and dry gluten content, test weight, grain hardiness, protein content and SDS sedimentation volume were studied. HMW and LMW glutenin subunits were evaluated using SDS-polyac...

power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
