Absorption Coefficients for Exciton Absorption Lines
Physical Review, 1957The absorption coefficient for excitons is calculated in the effective-mass approximation. The coefficient is shown to be decreased over what one would expect for a collection of free atoms by the factor ${\ensuremath{\epsilon}}^{\ensuremath{-}1}{(\frac{{a}_{0}}{{a}_{B}})}^{3}$, where $\ensuremath{\epsilon}$ is the dielectric constant and $\frac{{a}_{0}

Absorption takes place when a compound enters an organism, which occurs as soon as the molecules enter the first cellular bilayer(s) in the tissue(s) to which is it exposed. At that point, the compound is no longer part of the environment (which includes the alimentary canal for oral exposure), but has become part of the organism.

Absorption of Chlorhydroxyquinoline
Nature, 1963THERE has been some uncertainty about the fate of halogenated derivatives of oxine in the body1, but only a small part of an oral dose of Chlorhydroxyquinoline could be detected in the urines of rats1,2. In further experiments, traces were found in the blood of rats but the amount could not be estimated.

Material in the review on light absorption spectrometry is classified as chemistry, physics, and applications. Separate tables are given for photometric methods for metals, nonmetals, and organic compounds. 535 references are given to reports, patents, and U. S. and foreign journals and books published from September 1959 to October 1961.

Abstract.It is desirable to improve metabolic control in diabetics receiving insulin. Studies on insulin kinetics provide information that may be useful in the optimization of the injection scheme. Absorption has been measured using 1251‐insulin as marker and counting the residual activity with a crystal detector.

Abstract Carbohydrates, mostly as starch, are digested by salivary and pancreatic amylases to di-, tri- and oligosaccharides, then to monosaccharides by saccharidases on the wall of the small intestine, following which they are absorbed. Proteins are absorbed as amino acids and small peptides that are broken down further, in the cell, to amino acids ...
