abstractof two mcall programs introducing 100 vocabulary items through two im the researcher of the present study was intrigued to compare the effects age modalities (pictures and streaming video) with those of a conventional method (teacher instruction) in an efl context. she set out to investigate whether such multimedia environments could provide a more effective environment for vocabulary...
In this article CuO/water nanofluid was synthesized by using polyvinylpyrolidone (PVP) as the dispersant. Thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. To study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different pH values and PVP surfactant concentrations; also thermal conductivity...
in this study, parsley was dried using three drying methods: hot air (50, 60 and 70 ºc), microwave (90, 180, 360, 600 and 900 w) and a combination of hot air – microwave (60ºc and 360w). selection of the optimum levels for drying in combination method took place with quality tests of dried samples. the drying data of parsley with hot air and microwave methods was fitted with eight models: ...

drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
A novel composite adsorbent, Silica aerogel activated carbon was synthesized by sol-gel process atambient pressure drying method. The composite was characterized by Fourier transform infraredspectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry(DSC) and Nitrogen adsorption / desorption isotherms (BET).In the present study, the mentioned adsorbent was used m...
abstract aims: turbidity in higher than standard levels, indicates failure in the water treatment plant. an electrochemical disinfection process takes place through electricity transition between two or more electrodes. this research aimed to determine the reaction rate of electrochemical process for purification of polluted water. materials & methods: this is a bench scale, experimental study ...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
