Representation models are very important in Applied Computational Mathematics (Requicha, 1980), (Gomes & Velho, 1992). In this work we introduce a model for color space representation. Using this model we construct a mathematical framework that enables us to develop systematically the classical results in the area of colorimetry without the need to use Grassmann Laws as a basic set of axioms fo...

Results are presented of a continued investigation of the infrared colorimetry of the Martian bright and dark areas. Laboratory comparisons indicate that the infrared color profile of the Martian deserts matches that of a naturally occurring limonite stain which forms and is preserved on igneous rocks in a terrestrial desert environment. The co]orimetry of the Martian dark regions is compared t...

The book consists of fourteen chapters with an appendix and an index. Chapters 1 to 10 and 13 deals with experiments on carbohydrates, lipids, proteins, en?ymes, saliva, milk, gastric digestion, pancreatic digestion, bile, blood and urine. Chapter II deals with colorimetry and chapter 12 deals with estimations of various constituents of blood. The book will be very useful to students of biochem...

We compared thiobarbituric acid colorimetry and boronate chromatography for measuring glycation of serum proteins. With 14C-glycated human albumin as a test material, both methods were acceptably linear and precise. However, comparable estimates (mmol/L) of albumin glycation ranged from 0.22 for thiobarbituric acid to 0.05 for boronate, representing yields relative to [14C]glycosylprotein of 42...

In this nonenzymatic colorimetric method, dichlorobenzoquinone chloroimine is used as a color reagent to measure uric acid in urine. This method is less subject to the interferences that make enzymatic methods unreliable and is inexpensive, simple, and fast.

This article is the second in a series of review articles discussing the applications of color science in the clinical practice of dentistry. This installment discusses the colorimetry, which is the science and technology used to quantify and describe physically the human color perception. Theories of color space and clinically portable colorimetric devices developed for determining tooth shade...
