2014 Fast ellipsometers have made feasible real-time assessment of heterostructure growth in a vapour phase ambient. A fast ellipsometer/MO-VPE experimental system is described and the possibilities of in situ ellipsometry are investigated in the case of GaAs-(Al, Ga)As structure growth : qualitative assessment in real-time and quantitative assessment (growth rate, composition determination and...

Spectral measurements of various solidand liquid-propellent rocket plumes have shown the presence of strong emissions from sodium (589.6 nm) and potassium (766.5 nm). Theoretical calculations indicate that emissions near 589.6 nm should be efficiently transmitted through the atmosphere and clouds and thus should be easily detectable by a downward-looking sensor positioned above the clouds. To t...

Introduction Otitis media with effusion is the fluid in the middle ear with no signs or symptoms of acute ear infection. Objective This study aims to research the frequency of serous otitis media in patients referred to the pediatric clinic between 3-16 years of age without any active ear, nose, and throat complaints. Methods This study included 589 children patients (280 boys, 309 girls; mean ...

A graphic method of Drude equation was applied to a series of aldonic acid 1,4-lactones 1-7 to investigate possible Cotton effects below 200nm. The calculation shows three bands at 220nm, 170 nm and 130 nm to reflect the stereochemistries at C-2, C-4 and rtng conformations and vicinal OH at C-3 and C-4, respectively. The sum of the rotational contributions at 589 nm of these bands explained the...
