an investigation into oral interaction in language classes: a conversation analytic point of view the aim of this thesis is to analyze the interaction between language teachers and students in english language institutes. this work is done in the context of yasuj city. learning another language, which is in most cases english, involves many variables. one of these variables is the linguistic...
nano-cus powders were synthesized with chemical solution method. xrd and sem and spectrophotometry were used for characterization of the cus powders. xrd analysis indicated that tetragonal cus was the main phase with particle size of 16.2nm and little cu2s phase was present. scanning electron microscopy (sem) analysis revealed that powder was plate like and had very little aspect ratio in morph...
Photoinjectors are the main high brightness electron sources for x-ray free lasers (XFELs). Photoinjector emittance reduction is one of key knobs improving XFEL lasing, so precise measurement critical. It well known that rms very sensitive to low intensity tails particle distributions in phase space, whose depends on signal noise ratio and image processing procedures. Such sensitivities make in...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
in recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. these two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. in this paper i will consider the linear differential equations on the plane (phase diagram) and elements of nonl...
