Indicators of Mold Growth in Indoor Environments
… idea of using metabolic byproducts produced by mold as indicators of its presence in indoor environments in place of investigating airborne fungi by traditional particulate sampling techniques. VOCs and carbon dioxide are both examined in order to evaluate their usefulness as possible metabolic …

Design and Aerodynamic Analysis of Continuous Mold-line link flap
… the noise generated. A concept called continuous mold-line (CML) link flap has been studied rigorously for its impact on the acoustic behavior of the wing. These studies found that eliminating the blunt side tips with a continuous mold-line reduces the noise generated by the wing, drastically. …
