Application of Tracer Techniques to Continuous-flow Toxicity Testing

-Frequent toxicant analyses are essential for good quality data in long-term continuous-flow tests. Due to the time consuming and costly chemical analyses, exposure levels are measured at best on a daily basis. These infrequent determinations may not detect variability in toxicant concentrations that could result in test failures. To minimize repetitive testing and improve data quality, a dye t...

Application of magnetohydrodynamic actuation to continuous flow chemistry.

Continuous flow microreactors with an annular microchannel for cyclical chemical reactions were fabricated by either bulk micromachining in silicon or by rapid prototyping using EPON SU-8. Fluid propulsion in these unusual microchannels was achieved using AC magnetohydrodynamic (MHD) actuation. This integrated micropumping mechanism obviates the use of moving parts by acting locally on the elec...

Application of Model Comparison Techniques to Model Transformation Testing

In this paper, we discuss model-to-model comparison techniques that can be used to assist with model-tomodel transformation testing. Using an existing real-world model transformation, we illustrate and qualitatively evaluate the comparison techniques, highlighting the associated strengths and weaknesses of each in the context of transformation testing.
