This study was designed to determine cardiorespiratory and energy expenditure responses elicited by recreational divers while finning at a submaximal intensity (35% max) in cold (18°C) and warm (29°C) water with and without wet suits. Male divers (15) volunteered to participate in five experimental procedures. A maximal graded exercise tethered...
Research has been completed that evaluates two methods for the
extraction of polynuclear aromatic hydrocarbons (PNAH) from water.
The two methods compared were EPA Method 610, a liquid-liquid
extraction method, and a method involving PNAH adsorption on
commercially available short C₁₈ bonded phase columns, Sep-Paks,
in series with glass microfiber...

components of forest ecosystems and have been provided increased protection by the
Northwest Forest Plan. However, few studies have examined their distribution,
dynamics, and ecological roles, such as habitat for wildlife. My goal was to provide
additional information on the ecology...
This thesis will cover my work relating to the developing field of terahertz (THz) science and technology. It will present experimental and theoretical studies investigating the optical and electrical properties of various material systems using novel THz imaging and spectroscopy techniques. Due to its low photon energy, THz imaging and...
