In an effort to expand the disciplinary discussions on transfer in L2 writing and because most studies have focused on transfer as reuse and not as an adequate adaptation of writing knowledge in new contexts, the present study as the first of its kind aimed to explore the issue of adaptive transfer in an English for General Academic Purposes (EGAP) writing course. The study thus focused on type...

proton transfer (pt) and methyl group transfer (mgt) occurring in small biomimetic systems, formamide-formamidic acid (fa-fi), and n-formyl-n-methylformamide-(e)-methyl n-formylformimidate (nmfa-nmfi) are investigated in the gas phase and in single-walled carbon nanotubes by using the density functional theory and the oniom approach. it is shown that pt reaction is disfavoured in single-walled ...

using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...
