MICRO COLORIMETRIC STUDIES

The colorimetric micro-determination of long-chain fatty acids.

A Colorimetric Micro-method for the Determination of Glutathione.

1. A rapid colorimetric and apparently specific micromethod for the determination of total glutathione in small amounts of tissue is described. Generally, less than 30mg. of tissue is sufficient and this is homogenized in ice-cold 3% metaphosphoric acid. The product is filtered through sintered glass and neutralized or diluted before being added to a cuvette containing phosphate buffer, pH7.1, ...

Analytic and computational studies on micro-propulsion and micro-detonics

Based on a general theory of detonation waves with an embedded sonic locus that we have previously developed, we carry out asymptotic analysis of weakly curved slowly varying detonation waves and show that the theory predicts the phenomenon of detonation ignition and failure. The analysis is not restricted to near ChapmanJouguet detonation speeds and is capable of predicting quasi-steady, norma...

Studies with a new colorimetric test for proteinuria.

URING THE PAST HALF CENTURY a large number of tests for the detection of protein in the urine have been described. Three of these tests have gained outstanding popularity and are widely used in clinical practice. These are the sulfosalicylic acid test, the nitric acid ring test, and the heat and acetic acid test. Because of the wide usage of these tests as a part of “routine urinalysis” there i...

Comparative studies on micro heat exchanger optimisation

Although many methods for dealing with multi-objective optimisation (MOO) problems are available [Deb01] and successful applications have been reported [Coe01], the comparison between MOO methods applied to real-world problem was rarely carried out. This paper reports the comparison between MOO methods applied to a real-world problem, namely, the optimisation of a micro heat exchanger ( HEX). T...
