The Euler-MacLaurin sum formula has appeared in the titles
of two quite recent papers whose authors were primarily interested
in certain applications. In this paper a somewhat different approach
to the myriad of formulas for summation, integration, differentiation,
etc. , is based on the simple identity which defines the set...

North American beavers (Castor canadensis) are ecological engineers that improve biodiversity and can improve the health of riparian ecosystems. Beavers are generalist herbivores with some evidence of species preference, utilizing woody material for both food source and dam construction. In the South Slough National Estuarine Research Reserve, Charleston, Oregon, a...
Growing concern regarding the health effects of PFAS exposure through drinking water remains an issue at the forefront of many regulatory hurdles. Current data suggests that PFAS can be the cause of many negative health effects including changes in birth weight, thyroid disease, decreased fertility, and some forms of cancer....
This follow-up study investigated the effect of a systems-oriented graduate
training program upon system thinking among practitioners who had completed training,
using a post-test only, treatment-comparison group design. The subjects consisted of
practitioners matriculated through two counselor-related programs at a medium-sized
college in the Northwest during the years 1985-1991. A...
Pesticides are widely used to control undesirable pests and may be applied directly to water or lands directly adjacent to water. There can be unintended consequences, however, to native, threatened, and endangered species. There is little information on the impacts of aquatic pesticides and best management practices (BMPs) to NOAA...
Gamma irradiation survival curves of Salmonella enteriditis,
Salmonella paratyphi A, Salmonella cholerasuis, Salmonella
pullorum and Streptococcus pyogenes were determined in crabmeat
and in Hartsell's broth. The survival pattern of Staphylococcus
aureus in crabmeat was also determined.
A "tailing off" was found in the survival patterns of
Salmonella paratyphi A, Salmonella...
Part of the responsibility of maintaining the sanitary quality
of individual water supply systems has been placed on the local sanitarian
of Oregon. Because of this, he must be knowledgeable about
individual water supply systems. One such source of knowledge has
been the supply of written reference materials available in...
A procedural manual for sampling and analyzing sanitary landfill
leachate was designed to guide sanitarians and other public health
officials in monitoring mineral and organic material drainage from
landfill sources. The manual was constructed to allow flexibility of
conducting analytical tests in a field or laboratory environment.
Step-by-step procedures for...
This thesis examines depictions of medievalism in three central texts: Sir Walter Scott's Ivanhoe, Mark Twain's A Connecticut Yankee in King Arthur's Court, and George R.R. Martin's A Game of Thrones. Each of these texts provides an entry point for exploring the ways in which English and American writers have...
Gamma irradiation inactivation kinetics were studied using
fifteen organisms naturally contaminating seafoods. Survival curves
for seven Salmonella, three Shigella, two Streptococcus species and
a Staphylococcus, Escherichia and Proteus species were determined
using Hartsell's broth and fresh oysters. Also, the Shigella species
and one species of Streptococcus, Escherichia and Proteus were...
Studies were conducted under controlled conditions in order
to observe the resulting survival patterns in solid crabmeat of
Salmonella typhosa, Salmonella paratyphi B, and SaImonella wichita
following individual exposure to various doses of gamma radiation.
As shown in their survival curves, these species of Salmonella
exhibited in varying degrees a...
Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...
The purposes of this study were to determine whether the generally accepted procedure of campus elections as a method of choosing student government representatives (1) appears to encourage the candidacy of students who hold perceptions of the university environment similar to other students who do not choose to become candidates;...
The study was conducted to identify variables, from
among the theory related and demographic/biographic variables
included in the study, which were able to discriminate
between groups of male and groups of female freshmen
who differed in their level of self-actualization.
Five hundred and forty freshmen (277 males and 263
females)...
The purpose of this investigation was to determine the nature of the extractives from red alder bark in an effort to discover the materials which cause the red stain in red alder wood. Samples of bark and wood were obtained and successively extracted with hexane, benzene, ether, ethanol, and hot...
Six experiments were carried out with Single Comb White Leghorn laying chickens to
assess the effect of feeding a source of direct-fed microbials (Lactobacillus; Lacto) and its
carrier [condensed cane molasses solubles (CCMS)] on the retentions of fat, nitrogen and
several minerals; on the status of the pH of the...
Decentralizing resource control for community-based natural resource management (CBNRM) is a widely promoted scheme for natural resource governance worldwide. Researchers and policymakers have suggested that this approach has the potential to achieve positive social outcomes and succeed where centralized resource conservation has been inadequate. In reality, the powers transferred are...
Transcriptomics and gene expression profiling enables the elucidation of the genetic response of an organism to various environmental cues. Transcriptomics enables the deciphering of differences between two closely related organisms to the same environment and in contrast, enables the elucidation of genetic responses of the same organism to different environmental...
