while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
Prioritization of watershed basins includes classification of sub-basins on the basis of the existing conditions and erosion intensity, which ultimately leads to protective operations and watershed management in more significant and susceptible sub-basins. In this research, in order to prioritize Ghezel Owzan-Sefidrud sub-basins against sensitivity to erosion, linear and form-based morphometric...
Morphometric attributes of 705 stromatoporoid specimens from a number exposures the Silurian Podolia (Ukraine) and Devonian Holy Cross Mountains (Poland), representing wide array shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape skeleton, final growth form (living surface profile), upper character, latilaminae arrange...
multivariate analyses of the morphological variation in five geographical populations of the pod borer, helicoverpa armigera (hã¼bner), was performed using 15 and 12 landmarks selected from the fore- and hindwings respectively. using their geometric morphometric characters (26 in the forewings and 20 in the hindwings), 287 and 277 images of fore- and hindwings were made respectively. analyses o...
this research explains the morphometric characteristics of varroa destructor anderson and trueman in tehran province. 180 adult female mites were collected from three different colonies of apis mellifera l. in three apiaries during september 2003 to may 2004. these colonies were divided according to three altitudes-less than 1000m, 1000-1500m and more than 1500m above the sea level. the morphol...
