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...
This project strived to develop a prototype road piezoelectric energy harvester RPEH system using five Lead Zirconate Titanate (PZT) PZT 5H modules (stacks) that are embedded in the by means of housing unit harvest from vehicles stressing modules. The work is an extension our previous published same journal. design considered many factors optimize harvested energy. proposed first captures mecha...
Medical linear accelerators (linacs) are used efficiently in radiation therapy for tumor treatments. In these devices interaction of high energy photons (greater than 7 MeV) with the target, flattening filters, collimators and even body and patients bed produce secondary particles such as neutrons(photo-neutron production). The purpose of this study is measuring the neutrons dose produced in me...
Flame bending process is one of the forming processes of steel plates. During this process, plate is formed with heating by gas torch flame followed by controlled cooling along specified paths. Considering simple tools used in the process, it is a popular and economical forming method. At present, this process is manually done on the basis of skilled technician’s experience. Experimental and ...
