the significance of research article (ra) abstract as a key academic genre has recently motivated analysts to focus on this neglected area. considering a summary function for abstracts, most genre researchers have adopted the conventionally proposed introduction- method- results- discussion (or conclusion) (imrd) model for analysis. however, the problems reported, especially for results and dis...

babbitt is a white silvery alloy that composed of tin, lead, copper and antimony. this alloy is the most current bearing alloy in industrial applications. the characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. the target of this study is investigation on the effects of alloy elements on wearing and micro-struct...

Anode-supported micro-tubular solid oxide fuel cell (SOFC) offers many advantages over the electrolyte and cathode-supported confgurations in terms of simplicity, reliability, and efciency. In such design, the anode substrates should possess a highly porous structure, provide active sites reaction as well as serving good mechanical strength. This structure is desired to ...

highly crystalline bi3+-doped cadmium oxide (cdo) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. the reaction was carried out with cadmium nitrate (cd(no3)2.4h2o), bismuth nitrate (bi(no3)3.5h2o) and ethylene glycol (c2h6o2) reactants without any additives at 80°c for 2h. resulting gel was calcined at 900 °c with increasing temperature rate...

among factors that might manipulate translators’ mind while producing a text is the notion of ideology transmission through text or talk. adopting critical discourse analysis (cda) with particular emphasis on the framework of van dijk (1999), the present investigation is an attempt to shed light on the relationship between language and ideology involved in translation in general, and more speci...

We investigate three possible methods of specifying the microstructure of attention feedback: contrast gain, additive and output gain, using simple single node and 3-layer cortical models composed of graded or spiking neurons. Contrast gain and additive attention are also tested in a spiking network which is simplified by mean field methods. The simulation task uses two stimuli, probe and refer...
