One of the byproducts of shrinking features is increasingly complex film stacks and masking structures. Especially at critical levels, the simple deposit, pattern, and then etch process flows are no longer adequate. As an example, today’s etch processes often must account for anti-reflective coatings, hard masks, cap layers, and stop layers in the process recipe, while accurately etching the pr...
The present study aimed to investigate the interaction among grade dropping and reflective thinking abilities of the participants and to also check if action research enhances learners’ reflective thinking. A cyclic action research was run for 8 sessions. Kember et al.’s (2010) reflective thinking questionnaire and three in-term quizzes were administered. Students also made questions based on t...
The present study is aimed at investigating the relationship among Iranian EFL teachers’ reflective teaching, reflective thinking and classroom management ability. To this purpose, 102 male and female EFL teachers, aged between 25 and 40, with different academic background who were teaching at different levels, were chosen to fill in three questionnaires on reflective thinking, reflective teach...
This manuscript presents a first study of the contamination observed on some of the x-ray mirrors for the Linac Coherent Light Source (LCLS) free-electron laser, the implications to the mirror lifetime properties and an evaluation of candidate techniques towards successful recovery of these B4Cand SiC-coated mirrors. Initial experimental results and plans for upcoming mirror recovery experiment...
Reflective Teaching and Its Impact on Students' Achievement in English F. Ghorbaan Dordinejaad, Ph.D. M. Rashvand Reflective teaching as a style in teaching has shown to be effective across different academic areas, in which teaching English is no exception. To demonstrate its effectiveness, a sample of 70 English teachers in Ghazvin was asked to answer two sets of questions o...
Introduction: Reflective practice is a generic term for intellectual and affective activities that create new understanding and appreciation of experiences. Various studies have emphasized on the benefits of reflection in nursing. This article reviewed benefits and barriers of reflective practice in nursing. Methods: In this review article, library references, some scientific databases (Elsevi...
Laser refrigeration of solids has emerged as a viable solution for vibration-free and compact cooling that does not require any moving parts or cryogenic liquid. So far, rare-earth doped glasses are the only bulk materials that have provided efficient laser cooling based on the anti-Stokes process. These materials have low indices of refraction and are suitable for efficient luminescence extrac...
and Introduction: There are currently no electrically-pumped semiconductor lasers that can operate in the 1-5 terahertz (THz) spectral range at room temperature. An alternative method of producing room temperature THz light is based on intra-cavity difference frequency generation (DFG) in dual wavelength mid-infrared quantum cascade lasers. Our THz DFG sources can provide tunable output of over...
characterisation and corrosion performance of multilayernano nickel coatings on az31 magnesium alloy
ni-p and ni layers multilayer coatings were applied to az31 magnesium alloy utilizing electroless and electrodeposition procedures. the aim of the project was to decrease cracks and increase corrosion resistance of the coatings. in order to compare the coatings, the effect of single layer electroless ni-p coatings with different thicknesses was also investigated. the microstructure and phase co...
