A single oral dose of DDT, ranging from 40 to 200 mg/kg, had
a drastic effect on the in vivo acetate metabolism in rats. The normal
elimination pattern of the expired ¹⁴CO₂ from ¹⁴C-labelled
acetate was distorted, and the rate of output of the ¹⁴CO₂ was decreased.
The ratio of...
The purpose of this project was to optimize the biomass growth of Schizochytrium limacinum SR21. This was achieved by studying the effect of various concentrations of glucose, use of pure glycerol and purified crude glycerol as alternative carbon sources, and inhibition of cell growth with the presence of copper. The...

This study described how and why a Korean elementary teacher taught mathematics as he did. Specifically, the study sought to describe his beliefs about the teaching and learning of mathematics and relate them to patterns of classroom interaction and norms.
An ethnographic inquiry guided the study of one third grade...
Dissolved organic matter (DOM) is a critical component of the carbon cycle linking terrestrial and aquatic ecosystems. Although many factors influence DOM fluxes and quality in rivers, controls on DOM compositions in catchments of the western U.S. are poorly understood. UV and fluorescent spectroscopy is a simpler, faster, and less...
Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...
Sediment cores were retrieved from a landslide-dammed lake, recording events back to the 5th century AD in a forested, mountainous catchment. These cores provide an opportunity to compare the impacts of known recent perturbations, including floods and timber harvesting with those of the early period of the core, flood, fire,...
In the past, classification systems for the analysis of morphodynamic variability have been developed in an attempt to understand large scale coastal behavior. The motivation behind the creation of these classification systems has been to provide a framework of analysis, in order to understand large scale response to seasonal variability,...
