Calibration of Electric Moisture Meters for Some Wood Species Grown in Hawaii

Oct. 1964; 32 pp.; In English Report No.(s): PB2006-102802; FPL-061; No Copyright; Avail.: CASI: A03, Hardcopy

This Research Note presents species correction data for use with electric moisture meters in measuring the moisture content of five wood species grown in Hawaii, namely: saligna and robusta eucalyptus (Eucalyptus saligna and Eucalyptus robusta), silk-oak (Grevillea robusta), ohia (Metrosideros collina), and koa (Acacia koa). Indexes of direct current electrical resistance and radio frequency power absorption were obtained at a temperature of 80DG F. and at moisture content values ranging from about 6 percent to above the fiber saturation point for each species. The data were obtained using commercial moisture meters of both the resistance and radio frequency power-loss types. True moisture content was defined as that obtained by the ovendrying method. NTIS

Evaluation of Fugitive Emissions at a Former Landfill Site in Colorado Springs, Colorado Using Ground-Based Optical Remote Sensing Technology

Modrak, M.; Hashmonay, R. A.; Varma, R.; Kagann, R.; Apr. 2005; 54 pp.; In English Report No.(s): PB2006-103429; No Copyright; Avail.: CASI: A04, Hardcopy

A former landfill site located in Colorado Springs, Colorado was assessed for landfill gas emissions in support of reuse options for the property. The current owners of the landfill and the State of Colorado requested assistance from the EPARegion 8 Office, and the Office of Superfund Remediation and Technology Innovation, Technology Integration and Information Branch to perform a site assessment to search for the presence of any fugitive gas emissions from the site. The focus of this study was to evaluate fugitive emissions of methane and volatile organic compounds at the site in support of the reuse objectives, using a scanning open-path Fourier transform infrared spectrometer, open-path tunable diode laser absorption spectroscopy, and an ultra-violet differential optical absorption spectrometer. The study involved a technique developed through research funded by the EPA's National Risk Management Research Laboratory that uses ground-based optical remote sensing technology, known as optical remote sensing-radial plume mapping. The horizontal radial plume mapping (HRPM) method was used to map surface concentrations, and the Vertical Radial Plume Mapping (VRPM) method was used to measure emissions fluxes downwind of the site.
