Alternative names The term "propagation constant" is somewhat of a misnomer as it usually varies strongly with ω.It is probably the most widely used term but there are a large variety of alternative names used by various authors for this quantity. These include transmission parameter, transmission function, propagation parameter, propagation coefficient and transmission constant.
In acoustics, Stokes's law of sound attenuation is a formula for the attenuation of sound in a Newtonian fluid, such as water or air, due to the fluid's viscosity. It states that the amplitude of a plane wave decreases exponentially with distance traveled, at a rate α given by. where η is the dynamic viscosity coefficient of the fluid, ω is ...
Fluorescamine is a spiro compound that is not fluorescent itself, but reacts with primary amines to form highly fluorescent products, i.e. it is fluorogenic. It hence has been used as a reagent for the detection of amines and peptides.[2] 1-100 μg of protein and down to 10 pg of protein can be detected.[3][4] Once bound to protein the ...
Synthesis YOYO-1 is prepared by alkylation of N,N,N′,N′-tetramethyl-1,3-propanediamine with 2 equivalents of N-(3-iodopropyl) analogue of Oxazole Yellow, [2] which is available in three steps from 2-mercaptobenzoxazole: [3] YOYO-1 synthesis Photophysics The molar attenuation coefficient at the absorption peak of YOYO-1 is nearly 10 5 cm −1 M −1, among the high values of typical organic ...
The page Linear attenuation coefficient would be best removed and merged in a section on the page entitled "Attenuation coefficient". This way the the Linear attenuation coefficient can be described together with the mass attenuation coefficent in one article. Jdrewitt 15:14, 1 October 2007 (UTC) [] ...
Lichtenberg figure: high-voltage dielectric breakdown in an acrylic polymer block. Poly ( methyl methacrylate) ( PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands ...
