Effects of Short-term Low Intensity Laser and Ultraviolet Radiation on Embryos of Daphnia Magna [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2011 Short-term impact of the low intensity electromagnetic radiation on in vitro growing Daphnia magna Straus embryos was studied. Embryos were exposed to laser radiation (633 nm, 0.05 mW/cm2) and ultraviolet radiation (365 nm, 0.16 mW/cm2) separately as ...

Ultraviolet Background Radiation
Annual Review of Astronomy and Astrophysics, 1973 The results are reported of observations in narrow bands centered on 1115, 1425, and 1446 A of the flux from an empty high-galactic-latitude region and from several stars. The observations had been obtained with the aid of three ultraviolet-sensitive Geiger counters which were carried on an Aerobee-150 rocket launched from the White Sands missile ...
