N/A A micromachined fluidic structure for the introduction of liquid samples into a chip-based sensor array composed of individually addressable polymeric microbeads has been developed. The structure consists of a separately attached cover glass, a single silicon chip having micromachined channels and microbead storage cavities, and a glass carver. In our sensor array, transduction occurs via colorimetric and fluorescence changes to receptors and indicator molecules that are covalently attached to termination sites on the polymeric microbeads. Data streams are acquired for each of the individual microbeads using a CCD. One of the key parts of the structure is a passive fluid introduction system driven only by capillary force. The velocity of penetration of a horizontal capillary for the device having a rectangular cross section has been derived, and it is quite similar to the Washburn Equation calculated for a pipe with a circular cross section having uniform radius. The test results show that this system is useful in a p.-TAS and biomedical applications.

There is increasing worldwide interest in transforming building fire safety design from a prescriptive to a performance-basedenvironment. This interest is driven by the need to provide more cost effective fire protection, to provide greater flexibility infire safety design for complex and unusual buildings, and to provide tools to mitigate fire related hazards that folow otherextreme events, including earthquakes and terrorist atacks. Steel buildings are a class of structure that pose significanthehigh thermal conductivity of steel combined with the loss of stifness and strength of steel at elevated temperatures. This paperprovides a general discussion on the importance of improved structural-fire protection design for stel buildings. Recent majorfire events in steel buildings are reviewed, and key aspects of performance-based structural fire engineering are discussed.Building fire safety in general and structural fire safety in particular, provide good opportunities for implementing new sensorsensing and monitoring the overall thermal environment in a building and the temperature of steel building elements duringa fire.
