the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
We report high-resolution transmission electron microscopy (HRTEM) observation of a high density of dislocations with edge components (;10 m ) in nanocrystalline (NC) body-centered cubic (bcc) Mo prepared by high-pressure torsion. We also observed for the first time of the 1⁄2,111. and,001. pure edge dislocations in NC Mo. Crystallographic analysis and image simulations reveal that the best way...
Immunization of Lewis rats with acetylcholine receptor (AChR) purified from either Electrophorus electricus electric organ or syngeneic rat muscle induced experimental autoimmune myasthenia gravis (EAMG). This was demonstrated by clinical signs of weakness and by electromyographic evidence of imparied neuromuscular transmission. The amount of rat AChR required to induce an autoimmune response w...
With our recently developed deformation device, the in situ tensile tests of single crystal molybdenum nanowires with various size and aspect ratio were conducted inside a transmission electron microscope (TEM). We report an unusual ambient temperature (close to room temperature) super-plastic elongation above 127% on single crystal body-centred cubic (bcc) molybdenum nanowires with an optimize...
in o rder to stud v the possible use o r bhc against dln resistant a. stephensi mysorensis and with a view to determining the va lue of this insecticide in the control or malaria transmitted by th is vector, a field experiment (a rea sca le) was ca rried o ut in the khesht area. kazcroun, southern iran. during 1963. 32 vi llages with a population or 11 . 173 persons were sprayed wit h gamma-bhc...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
The discharge muffler of the rotary compressor is used to reduce the discharge noise produced by pressure pulsations. In order to obtain the transmission loss of discharge muffler, four microphone experimental devices used to measure the transmission loss of the muffler is established. The device is based on the transfer function method on the assumption that there is only plane wave in the tub...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
The buried hetero-structure (BH) InGaAsP-InP waveguide is used for asystem of double microring resonators (DMR). The light transmission and location ofresonant peaks are determined for six different sets of ring radii with different ordermode numbers. The effect of changing middle coupling coefficient on the box likeresponse is studied. It is found that the surge of coupling coefficient to the ...
