High Temperature Materials for Aerospace Applications
(2011-08-08)
Further crosslinking of the fluorinated polyimide was examined to separate the
cure reactions from degradation and to determine the optimum post curing conditions.
Glass transition/melting temperatures were ascertained ...
Effect of Bioreactor Mode of Operation on Mixed-Acid Fermentations
(2012-10-19)
Using mixed-culture fermentation, the carboxylate platform produces carboxylic acids, which are chemically converted into chemicals and fuels. To optimize the mixed-acid fermentation, different bioreactor configurations ...
CTCF Contributes to the Regulation of the Ribosomal DNA in Drosophila melanogaster
(2012-02-14)
The 35S rDNA gene clusters on the X and Y chromosomes of Drosophila melanogaster are repeats of approximately 150 to 225 copies. Each are transcribed as a single unit by RNA Polymerase I and modified into the 18S, 5.8S, ...
Synthesis and Characterization of Iso-Reticular Metal-Organic Frameworks and Their Applications for Gas Separations
(2011-10-21)
Nanoporous metal-organic frameworks (MOFs) have attracted tremendous
interest due to their potential applications in gas-storage, gas separation, gas sensing, and
catalysis. MOFs consist of metal-oxygen polyhedera ...
Numerical Investigation of Flow Fields and Forces for 2-D Squeeze Film Dampers
(2011-08-08)
A numerical method is used to predict flow fields and forces for squeeze film dampers (SFDs). A two dimensional SFD is modeled with different amplitudes and frequencies of the journal orbiting inside the wall. In addition ...
Intelligent executive guidance agent for general aviation aircraft under free flight
(Texas A&M University, 2002)
Conflict detection and resolution is a critical capability for the realization of free flight, a new concept of air traffic management that allows pilots to select their own flight paths and airspeeds in real time. A ...
