Influence of surface tension and concentration of a non-ionic surfactant on the barrier effectiveness of a microporous polypropylene fabric for pesticide protective clothing
… solutions of a non-ionic surfactant on the barrier effectiveness of a fabric containing microporous polypropylene (PP) film that may be used in pesticide protective clothing (PPC). Aqueous solutions of Triton® X-100, a non-ionic surfactant, at various concentrations were prepared, and the γ …

In-situ tests of sound-bubble-strobe light barrier technologies to prevent the range expansions of Asian carp
… and Ship Canal. Sound-bubble-strobe light barrier (SBSLB) technologies may have the potential to slow Asian carp range expansions. A sound-bubble barrier was 95% effective at deterring adult bighead carp passage in a hatchery raceway experiment. In 2009-2010, I tested the effectiveness of a …

A Derivation Of An Empirical Equation For Estimating The Acoustical Shadow Zone Length Of Roadway Noise Barriers
… shadow zone length (SZL) of roadway noise barriers. The acoustical shadow zone is the area behind a noise barrier of reduced sound levels, generally to some stated level at or near background. The ability to predict the SZL can be used as a method to evaluate the performance, and possibly …
