During the past 10 years the embryos and larvae of oysters and some species of clams have been employed to quickly assess the biological effects of various substances in marine water samples. The best materials have included some insecticides, herbicides, antibiotics, detergents, a variety of other compounds, and a few...
This report contains a summary of three separate continuous flow tests conducted on Pacific and Kumamoto oysters following a series of preliminary spent sulfite liquor (SSL) bioassays in 1958.
Fisheries Laboratory during 1952, in the rearing of the native Pacific Coast oyster, Ostrea lurida Carp., in small containers. The decline of the oyster fishery in Yaquina Bay, Oregon, has been attributed in part to the lack of adequate spat-falls. Investigations were begun in 1947 to devise methods of artificially...
This report is a brief overview of the status of Oregon’s oyster aquaculture in the mid to late 1970s, including discussions of trends in harvests and research into oyster breeding.
Beginning in the late 1960s and throughout the past decade, unusual, perhaps neoplastic, large cells with rather consistent characteristics were described in mussels, clams, and oysters from several bays in the United States and the United Kingdom. The large, characteristic cells are thought by many workers to be abnormal leukocytes...

For oysters, "The objective of these studies was to determine the biological feasibility of using the heated effluent from coastal nuclear power plants for culturing the Pacific oyster, Crassostrea gigas." (p.1) Work included oyster growth experiments, seasonal growth experiments and closed system studies. For salmon, "The objective of these studies...

The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

Abstract Watershed-scale fate/transport modeling of contaminants is a tool that scientists and land managers can use to assess pesticide contamination to stream systems. The Catchment Modeling Framework (CMF) is a catchment-scale fate/transport modeling tool. It was developed to help scientists and land managers assess the effects of possible land-use decisions...
The Oregon State University (OSU), Hydro Mechanical Fuel test Facility (HMFTF) is designed
to hydro-mechanically test prototypic plate type fuel. OSU’s fuel test program is a part of the
Global Threat Reduction Initiative (GTRI), formerly known as the Reduced Enrichment for
Research and Test Reactor program. One of the GTRI’s...
Ein Kultursystem wird beschrieben, das zur Zucht von Decapodenlarven und anderen kleineren Wassertieren geeignet ist. Es besteht aus einem rechteckigen Zuchtgefäß mit schräg abfallendem Boden, an dessen seichtem Ende Wasser einströmt, so daß eine abwärtsgerichtete Bodenströmung entsteht. An dem tiefen Ende des Zuchtbeckens wird durch eingeleitete Luft das Bodenwasser nach...

The formation mechanisms and pathways of intermediate water in the Southern Ocean are analyzed from output of a high-resolution ocean general circulation model. Deep winter mixed layer formation in the Southern Ocean is diagnosed from the model results and is found to be mostly consistent with observations. Diapycnal water mass...
This laboratory bioassay focused on lethal and sublethal effects of five
insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and
mancozeb) on the predatory mired bug Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using
second instars and adult males and females. Formulated...
This publication is one of a set written to help consumers select and care for today's clothing. Three of the publications -- fibers and fabrics; information found on garment labels; and dyeing and colorfastness -- aid consumers in evaluating clothing and household textiles.

To determine if squirrels (Sciurus douglasii var.) cut cones before the seeds are ripe, a series of collection points was established in the Willamette Valley and the Cascade Mountains in the summer of 1954. The areas were inspected at intervals during August, September and October of 1954, and freshly cut...
Radiation damage caused by fission fragments to metal surfaces is an important research topic. Thin titanium foils were irradiated with a continuous wave beam of 132 MeV ¹³²Xe+²⁹ at the current intensity of 2 pnA. Pre- and post-irradiated surface topologies were investigated using atomic force microscopy and the observed defects...

Angiogenesis is an essential process for disease progression in many solid tumors. There are several major cascade events in the angiogenic process that can be targeted to inhibit new blood vessel formation in the tumor tissue. The purpose of this work is to evaluate the inhibitory effect of paclitaxel (PTX)...

Capturing the spatial distribution of high-intensity rainfall over short-time intervals is critical for accurately assessing the efficacy of urban stormwater drainage systems. In a stochastic simulation framework, one method of generating realistic rainfall fields is by multiplicative random cascade (MRC) models. Estimation of MRC model parameters has typically relied on...
Ecosystem process models are important tools for determining the interactive effects of global change and disturbance on forest carbon dynamics. Here we evaluated and improved terrestrial carbon cycling simulated by the Community Land Model (CLM4), the land model portion of the Community Earth System Model (CESM1.0.4). Our analysis was conducted...
