quantification of the habitat available for fish species named rainbow trout (oncorhynchusmykiss) were evaluated in lees ferry, colorado river using water depth, water temperature, sediment transport,flow velocity in 2004 as environmental index. for the flow velocity and temperature distribution calculationsin the river, the navier-stokes equation and energy conservation equations with finite v...
the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
This study compared farmers’ rating of extension effectiveness in technology dissemination to the level of adoption. In conducting the study, 180 farmers participating in extension programme in Cross-River State were randomly selected through multi-stage random sampling technique. The data collected through a structured questionnaire were analyzed using the t-test of significance of difference ...
this study investigated the comparative effect of teaching idiomatic expressions through practicing them in conversation and paragraph writing on intermediate efl learners’ idiom learning. the participants were sorted out of a population of 134 intermediate students in zabansara language school in khorramabad based on their scores on a preliminary english test (pet) and an idiom test piloted in...
Rating curves are widely used for directly assessing changes in the suspended sediment delivery process and indirectly for estimating total yields. Four sampling methods were simulated over a 31-day record of suspended sediment from the North Fork of the Mad River near Korbel, California. The position and size of the four groups of plotted slope/intercept pairs indicated differences in bias and...
Cop Abstract: Event sediment transport and yield were studied for 45 events in the upstream part of the 260 km agricultural Koga catchment that drains to an irrigation reservoir. Discharge and turbidity data were collected over a period of more than a year, accompanied by grab sampling. Turbidity was very well correlated with the sediment concentrations from the samples (r = 0.99), which allowe...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
The sediment load that is transported by rivers can create numerous problems such as sedimentation in the reservoir and storage capacity reduction, developed load in the rivers, destruction of structures along the river and transfer of pollution. Therefore, an accurate estimate of the sediment load in rivers is absolutely essential for river engineering, reservoir design, sediment transportatio...
