Reference...
Background: There is a long-term interest in running the fission reaction backward, i.e., studying the "inverse fission" of uranium. The recent availability of beams of n-rich fission fragments has stimulated interest in this endeavor.
Purpose: To search for inverse fission in the reactions Sn-¹²⁴,Sn-¹3² + Mo-¹⁰⁰.
Method: In the Sn-¹²⁴...
Air pollution epidemiological studies suggest that elevated exposure to fine particulate matter (PM₂.₅) is associated with higher prevalence of term low birth weight (TLBW). Previous studies have generally assumed the exposure–response of PM₂.₅ on TLBW to be the same throughout a large geographical area. Health effects related to PM₂.₅ exposures,...
Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...
During the Canterbury Earthquake Sequence (CES) in Christchurch, NZ, an estimated $15B in damages occurred due to liquefaction-induced phenomena, illustrating the importance of understanding site-specific responses to seismic ground motions, as well the importance of accurately predicting liquefaction severity. One potential method for improving the understanding of how a site...
Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...
A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...
Most existing analyses of the blade loads on horizontal
axis wind turbines are conducted using linear steady-state
aerodynamics, but evaluation of loads resulting from wind
turbulence or gusts may not be adequate using these
techniques. This study develops single-parameter
approximations for both the shed wake and trailing wake
components of...
Techniques have been developed for measuring the
temperature, stable species concentrations, and atomic
radical concentrations during a transient combustion
event. They combine the features of direct sampling with
two spectroscopic techniques to produce relatively simple
diagnostic techniques to obtain time-resolved
measurements. In this study, a transient event was
provided by...
The term Euclidean zoning is derived from the famous case
of Euclid vs. Ambler Realty Company in which the U.S. Supreme
Court upheld the right of the town of Euclid to zone land on the
basis of land use categories (e.g. residential, commercial, and
industrial). Since Euclid, the field of...
This paper considers the regulation of a natural resource within a dynamic common agency framework. In setting harvest quotas, the regulator responds to lobbying pressure (contributions) from harvesters and conservationists. The truthful Markov perfect equilibrium stock is then an increasing function of the effective political weight for conservationists. Since the...
Two direct elicitation of utility (D.E.U.) techniques
were used to estimate risk attitudes of a group of agricultural
producers. The two elicitation techniques used in the
study were 1) an error-in-response model using a modified
Ramsey method, and 2) stochastic dominance with respect to a
function (SDF). The primary objective...
The "unusual" behavior of agricultural land prices is the subject of considerable debate and controversy and is the object of this research. There is little doubt that land prices have been increasing steadily since 1959 and dramatically throughout the decade of the 1970's. However, there is widespread disagreement among economists,...

A laboratory investigation was performed to determine the influence of 2,4-dichlorophenol on the flavor of fish. The study was conducted at the Oak Creek Fisheries Laboratory of the Department of Fisheries and Wildlife, Oregon State University. The three experimental apparatus used in this study were designed to deliver 250 ml/min...
Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...
As part of the effort to evaluate TRIM (Timber Resource Inventory
Model) for the next RPA National Assessment, a study was conducted

The supply of raw material to the Norwegian fish processing industry has always fluctuated heavily, both as far as volumes and quality are concerned. These fluctuations have had major impact on planning of for instance product mix and production capacity. Thus, sea farming has been considered a promising alternative source...
The impact of vertical integration (VI) on performance is an often-addressed topic in both management and
economic studies. The contradicting conclusions based on different theoretical perspectives regarding this impact cause
need for empirical studies. Empirical work, however, has lagged behind. In fact, few studies have in a convincing way
demonstrated...
On the background of the abolishment of traditional subsidies this paper discusses the persistency of the major remaining subsidy scheme in Norwegian fisheries: exemption from fuel taxes. The reimbursement scheme stems from the late 1980s, and has been persistent since, under different governments. This paper gives the background for this...
A vegetation classification based on concepts and methods developed by Daubenmire was used to identify five habitat types and their related phases on the Medicine Bow National Forest: Abies lasiocarpa/Vaccinium scoparium, including the Pinus contorta/Vaccinium scoparium community; Abies lasiocarpa/Carex geyeri, including the Pinus contorta/Carex geyeri community; Populus tremuloides/Carex geyeri; Pinus...
We have expanded on the results of an earlier paper [J. Chem. Phys. 72, 221 (1980)] which deals with a method for determining the response of a static, partially ordered ensemble of molecules to various types of electromagnetic probes. In this paper we consider types of spectroscopy whose response depends...
This paper discusses the persistency of one of today’s major subsidy schemes in Norwegian fisheries: exemption from fuel taxes in the fishing fleet. The reimbursement scheme stems from the late 1980s, and has been persistent since, under different governments. Here we provide the background for this support and discuss it’s...
Though the commercial value per pound of Pacific halibut (Hippoglossus stenolepis) is greater than that of most target species in trawl fisheries off Alaska, halibut retention is prohibited for trawlers and individual groundfish target trawl fisheries are subject to closure if they attain either their seasonal or annual limit of...
The event-scale variability of across-shelf transport was investigated using observations made in 15 m of
water on the central Oregon inner shelf. In a study area with intermittently upwelling-favorable winds and
significant density stratification, hydrographic and velocity observations show rapid across-shelf movement of
water masses over event time scales of...
The spatial and temporal variability of inner-shelf circulation along the central Oregon coast during the
2004 upwelling season is described using a 70-km-long array of moorings along the 15-m isobath. Circulation
at three stations located onshore of a submarine bank differed from that of a station north of the bank,...
We use data from a series of small (three to five stations) overlapping magnetovariational (MV) arrays to image variations of vertically integrated electrical conductivity in the crust of southwestern Washington. Two principal structures are revealed: a large north-south trending anomaly (the southern Washington Cascades Conductor (SWCC), which has been detected...
In a companion paper (Egbert et al., this issue) we describe the estimation of very long period (0.16 < T < 91 days) magnetotelluric (MT) impedances from 11 years of data collected at the Tucson geomagnetic observatory. Here we discuss the implications of these data for mantle conductivity. Using minimum...
