Refractive index of solutions at high concentrations

Applied Optics, 1988
The refractive index of liquid solutions at the He-Ne laser wavelength, 0.6328 microm, is presented. The measurements were carried out using the conventional minimum deviation method of an equilateral hollow glass prism. The refractive indices of sucrose, sodium chloride, glucose, and caster sugar solutions for a range of density varying from distilled

A note on the decomposition of the health concentration index

Health Economics, 2002
AbstractIn recent work, the concentration index has been widely used as a measure of income‐related health inequality. The purpose of this note is to illustrate two different methods for decomposing the overall health concentration index using data collected from a Short Form (SF‐36) survey of the general Australian population conducted in 1995.

Refractive Index of Concentrated Protein Solutions

Nature, 1954
AN accurate knowledge of the specific refraction increment α, or dn/dC, of proteins is important in measurements which involve the use of the ultra-centrifuge, electrophoresis and light-scattering. Recently, it has become important in connexion with cytological methods of refractometry1 and mass determination2 of living cells.

Uniqueness of concentration index

Journal of Financial Engineering, 2014
This paper establishes axioms for concentration index (CI) and its allocation function. It proves that the Herfindahl index (HI) and the square allocation function are the only one that satisfies these rules.

Open Concentration Index

Proceedings of the 12th International Symposium on Open Collaboration, 2016
The market concentration is a measure of competition and, as such, is closely monitored by public competition authorities in the European Union or the United States. Among recent claims in Europe, we study the case of the mobile operating system Google Android, despite its open source quality and the fact it can as such be regarded as presenting no ...

A note on zenga concentration index

Journal of the Italian Statistical Society, 1995
The Zenga index, , is shown to be a concentration index, in the sense that, ifX andY are non negative random variables with ...

A comparison between the g‐index and the h‐index based on concentration

Journal of the Association for Information Science and Technology, 2015
I discuss how, given a certain number of articles and citations of these articles, the h‐index and the g‐index are affected by the level of concentration of the citations. This offers the opportunity for a comparison between these 2 indices from a new perspective.

The Apparent Free Testosterone Concentration, An Index of Androgenicity

The Journal of Clinical Endocrinology & Metabolism, 1971
ABSTRACT As free non-protein bound testosterone is generally considered to represent the active androgen fraction in plasma, we developed a method, based on equilibrium dialysis of diluted plasma, by which the “apparent free testosterone concentration” (AFTC) in undiluted plasma is obtained. This AFTC was determined in normal adult, (pre)adolescent and

Graded-index planar waveguide solar concentrator

Optics Letters, 2014
Planar waveguides are useful to transport, concentrate and distribute light uniformly over large dimensions. Their capacity to collect and gather light efficiently over a large distance is interesting for many applications, like backlighting and solar concentration.

The Lerner index and measures of concentration

Economics Letters, 1979
Abstract The paper investigates the relationship between price-cost margins (the Lerner index) and measures of seller concentration. It shows that previous disparate conclusions on the appropriate concentration measure are special cases that can be reconciled in a more general formulation.
