Science
All compounds were detected with a refractive index detector, except for HMF and furfural which were detected with a UV-detector (210 nm).
Science
This prospective study examined forty-six eyes (only the right eye) of 46 healthy volunteers without ophthalmological disease except for refractive error, whose mean age was 31.4 ± 11.2 years (range: 20 to 57 years), whose mean spherical equivalent refractive error was −2.44 ± 2.31 D (range: −6.50 to +1.36 D), and whose mean corneal astigmatism was −1.19 ± 0.65 D (range: −3.00 to −0.25 D).
Fifteen eyes of 9 healthy volunteers who did not have any ocular diseases except for refractive errors were studied.
Twelve healthy volunteers (six males and six females) aged 21 to 47 years (mean 32.6 (SD 8.2) years), who had no history of eye disease except for refractive errors, were enrolled in the study.
Except for some particular refractive indices, where resonances are observed, the optical torque first grows as N im increases from low values, thus reinforcing the fact that absorption is directly related to the SAM transfer.
Science
The buried amorphous layer possesses a significantly reduced refractive index thus acting as a refractive index barrier for waveguiding.
A refractive index detector was used for compound detection for both columns.
Science
Ice has a refractive index of 1.31, for example; air has an index of 1.
