the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...

Plant roots, with respect to their intrinsic characteristics, have important role in both improvement and development of germplasms of drought resistant plants. This experiment was conducted to study direct and indirect effects of root morphological traits on grain yield of four triticale genotypes (three promising lines of ET-82-8, ET-82-15 and ET-79-17 along with the conventional Junillo-92...

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...

Among the crops, cereals have been special important and triticale is the most successful man made cereal. In present research, water deficit stress effects on 19 triticale genotypes (X Triticosecale wittmack) and two wheat cultivars (Triticum aestivum), Shiraz (sensitive to water deficit stress) and Kavir (tolerant to water deficit stress) were tested. Therefore, two separate field experiments...

At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...
