A mathematical model of the external respiratory system is presented which integrates component models of airway mechanics and gas exchange at the pulmonary capillaries. The respiratory system is lumped into: (1) a conducting ...

In this work, rapid TNT ($>$150 mg/L) transformation by Clostridium acetobutylicum via a reductive pathway to monoaminonitrotoluenes, diaminonitrotoluenes, and on to undetectable end products was observed. The maximum ...

Vascular endothelium responds to hemodynamic forces such as shear stress by altering the synthesis and genetic expression of several proteins. Shear stress sensitive promoter elements and transcription factors may be ...

The rpoS protein, $\rm\sigma\sp{s},$ is responsible for regulating the expression of a wide array of proteins. Believed to induce $\rm\sigma\sp{s},$ homoserine lactone (HSL), a threonine pathway derivative, has been ...
