Artwork: A glass prism splits white light into a spectrum. Nature recreates Newton's famous experiment whenever you see a rainbow! Everyone loves a rainbow, but where do those amazing colors come from? Most people understand that raindrops split sunlight ("white"light) into its component colors...
frequency between \(\omega _{1}\) and \(\omega _{2}\) for that purpose, which can be combined with an active compensation method involving a tunable delay, e.g., consisting of a movable right-angle prism with a piezo-actuated translation stage, or a piezoelectrically controlled fiber ...
Our results show that the drainage density of tidal channels is linearly related to the landscape-forming prism, although this relation is speculated to hold with reasonable approxima-tion as a statistical tendency rather than as a pointwise, instan-taneous adaptation. Changes in tidal prism rapidly...
Apply magnetic tape to the glass side. (Cleaning, if necessary, should be done by holding the mirror side downward in a bowl of alcohol and swirling it in a circular motion. Do not wipe or touch the mirror sur- face.) No. 45-646 Qty. 2 Optical Elements Triangular Prism The prism ...
The expression levels of the 20 housekeeping genes were analyzed using a qPCR system (Applied Biosystems ABI PRISM 7500). The qPCR analysis was per- formed with a 20-μl solution containing 1 × Premix Ex Taq, (Takara-bio), 1 μM of each primer pair, and 0.25 ...
