Abstract: The invention consists of an improved heat exchange conduit formed between pre-fabricated building panels and a daylighting section integral within pre-fabricated, structural panels. The daylighting section has the capability to take ceiling air (or air below free-standing arrays) and either return it to the building during heating months, reject the heat, or shunt it for other uses after being warmed through a dual pane glazing assembly with infrared rejection. During summer days, this allows for dramatic reduction in building cooling demand. Heat exchange surfaces within the conduit are thermally tied to the exterior components of the panels to allow heating by solar insolation or cooling to night sky or air. An advanced insulation system adds to thermal performance and sealed insulation cavities prevent moisture degradation of R-Values. Passage through the heat exchange conduit allows for active whole roof solar collection in spring/fall and night cooling capability during summer night operation.

Abstract: Bioprosthetic tissues are treated by immersing or otherwise contacting fixed, unfixed or partially fixed tissue with a glutaraldehyde solution that has previously been heat-treated or pH adjusted prior to its contact with the tissue. The prior heat treating or pH adjustment of the glutaraldehyde solution causes its free aldehyde concentration to decrease by about 25% or more, preferably by as much as 50%, and allows a “stabilized” glutaraldehyde solution to be obtained at the desired concentration and pH for an optimal fixation of the tissue at high or low temperature. This treatment results in a decrease in the tissue's propensity to calcify after being implanted within the body of a human or animal patient.
