Abstract. We demonstrate the capability of Sentinel-2 MultiSpectral Instrument (MSI) to detect and quantify anomalously large methane point sources with fine pixel resolution (20 m) rapid revisit rates (2–5 d). present three column retrieval methods that use shortwave infrared (SWIR) measurements from MSI spectral bands 11 (? 1560–1660 nm) 12 2090–2290 atmospheric plumes. The most successful is...
Magnetically enhanced, capacitively coupled radio frequency plasma sources are finding continued use for etching of materials for microelectronics fabrication at a time when multifrequency sources are also being developed. Magnetically enhanced reactive ion etching MERIE sources typically use magnetic fields of tens to hundreds of Gauss parallel to the substrate to either increase the plasma de...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
