VIII. METHYL VIOLET TEST PAPER.

Photobleaching of cresyl violet in poly(methyl methacrylate)

This study investigates the rapidity with which an optical dye in a solid plastic host irreversibly degrades when it is brightly illuminated by visible light. Specifically, the organic dye cresyl violet perchlorate dispersed in plexiglas was optically excited by a continuous-wave dye laser pumped by an argon-ion laser. After resonantly absorbing and emitting many times, an individual dye molecu...

Removal of Methyl Violet and Auramine Yellow from Stishovite Clay

The adsorption behaviour of Methyl violet and Auramine yellow from aqueous solution onto Stishovite clay was investigated as a function of parameters such as initial dye concentration, contact time, p and temperature. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. Adsorption followed pseudo-second order model. The experimental data fitted well ...

The Agglutinatiun Test with Brucella Sera Absorbed into Filter Paper

Paper chromatography of methyl esters of porphyrins.

A micromethod for detecting and determining various porphyrins extracted from biological materials, especially nervous tissues (I), is needed. The technique of filter paper chromatography by Consden, Gordon, and Martin (a), with modification by Williams and Kirby’s capillary ascent (3), has been applied to the problem in this study. The recent paper by Nicholas and Rimington (4) on partition ch...

SSC01-VIII-6 A Highly Modular Scientific Nanosatellite: TEST

A powerfully instrumented, reliable, low-cost 3-axis stabilized nanosatellite is in final design using novel technologies. The Thunderstorm Effects in Space: Technology (TEST) nanosatellite implements a new, highly modular satellite bus structure and common electrical interface that is conducive to satellite modeling, development, testing, and integration flow. TEST is a low-cost ($0.1 – 0.2 M)...
