The normal incidence sound absorption coefficient
([alpha]) is defined by the following equation

of Ekoprena latex foam at different densities
According to the Beer-Lambert Law, the optical density at the fixed wavelength is proportional to the absorption coefficient
of chemical compositions of bacteria.
The absorption coefficient
is ten times smaller in pure silica that in the nanostructured samples with embedded SiQDs according spectroscopic measurements.
To investigate the correlation between the penetration behaviors of chloride and water, the relationship between the maximum absorbed water amount and the maximum chloride content, as well as the capillary absorption coefficient
of water and diffusion coefficient of chloride, is described in Figures 5(a) and 5(b), and the results show that they follow a linear relation.

Such simulations provide analytical parametrization for emission and absorption coefficients
in a wide range of [gamma]-ray energies (frequencies) produced in microquasar jets [12,28].
(1) Sound absorption coefficient
(SAC) of all OPT fiber with an average density of 200 kg/m3 showed minimum value of around 0.60 at frequency range from 3000 - 6400 Hz.
The recorded signals in the analyzer in terms of the transfer function between the microphones were processed using Bruel & Kjaer material testing software to obtain the absorption coefficient
of the sample under test.

of "pure" seawater in the range of 350-550 nm inverted from remote sensing reflectance.
The intensity attenuation is mainly caused by the evanescent field absorption coefficient
[[gamma].sub.m] of the MF.
where [tau] is the transmittance of a medium and [kappa] [[m.sup.-1]] is the medium absorption coefficient
. Here, [kappa] depends on the composition of the medium (i.e., particular mixture of molecules along the channel) as follows:
