Alerting effects of short-wavelength (blue) and long-wavelength …
SpletIn each application, the long-wavelength tracer was superior to the short-wavelength tracer regarding depth of penetration, signal-to-background ratio, and frequency of event. Pafolacianine was more effective for detecting subpleural lesions (mean signal-to-background ratio=2.71 vs 1.73 for folate-fluorescein, P <0.0001). Spletpolychromatic short-wavelength-enriched light on a cognitive per-formance task during the first hour after waking.

Alerting and Circadian Effects of Short-Wavelength vs. Long …
SpletWhen aiming two pyrometers, one with a carefully selected short wavelength (Pyrometer A) and one with a long wavelength (Pyrometer B) about 2 meters into the soaking zone (where the combustion gas and the product temperature are about the same) both sensors will read the same temperature value. SpletThe impact of wavelength and pulse duration in laser cleaning of hard blackish contaminants crust from archaeologically significant Pleistocene bone is investigated in this research. The objective is to determine the practical cleaning procedures and identify adequate laser parameters for cleaning archaeological bone from Sima de los Huesos … SpletTwo molecules in which the intensity of shorter-wavelength fluorescence from a strong fluorophore is modulated by longer-wavelength irradiation of an attached merocyanine–spirooxazine reverse photochromic moiety have been synthesized and studied. This unusual fluorescence behavior is the result of quenching of fluorophore … how can cashless transactions help an economy
