Thermal regimes of forested headwater streams control the growth and distribution of various aquatic organisms. In a western Oregon, USA, case study we examined: (1) forested headwater stream temperature variability in space and time; (2) relationshi

An experimental X-ray powder diffraction pattern was produced and analyzed for alpha-polymorphic tegafur, also called Ftorafur (an antineoplastic agent). The indexed data matched the powder patterns in the ICDD PDF-4/Organics database calculated from

OBJECTIVE: The objectives of this study were to develop a measure to assess patients' response to civil commitment, to test this measure on two groups of dually diagnosed patients (medically ill alcoholics and patients with dual mental and substance

This report documents the findings of a quasi-experimental study of a new approach to treating medically ill alcoholics. The intervention, the Alcohol Related Disorders (ARD) Clinic, consists of concurrent alcohol treatment and medical care delivered

The amphibian fungal pathogen Batrachochytrium dendrobatidis (Bd) has received considerable attention due to its role in amphibian population declines worldwide. Although many amphibian species appear to be affected by Bd, there is little information

Measurement of optical absorption loss and photorefractive sensitivity (optically induced index changes) in Ti-diffused waveguides and bulk Ti-doped single crystals are reported. The absorption loss of strip guides is found to be 0.3 dB/cm at 0.633 m

Single-pulse and cw measurements of the response of a semi-insulating CdZnTe/ZnTe multiple-quantum-well photorefractive device are presented. In single-pulse experiments, photodiffractive (absorption) gratings have been written with less than 1.8-mic

We have performed photodiffractive four-wave mixing in semi-insulating multiple GaAs/AlGaAs quantum wells at a wavelength of 0.83 microm. The quantum wells were made semi-insulating by proton implantation, which introduces defects that are available

Order-of-magnitude improvement of the quantum efficiency of metal-oxide-metal detectors is achieved in the visible spectrum by fabricating the devices on silica substrates structured with a periodic array of bumps separated by about 0.25 microm. Stru

Absorption, luminescence, and excitation luminescence studies of dye molecules adsorbed onto ultrathin, variable-thickness silver films show strong coupling of the particle plasma resonances to the molecules. Luminescence from the dye is increased by
