The growth and food consumption of juvenile coho salmon [Oncorhynchus kisutch (Walbaum)] exposed to natural and elevated fluctuating temperatures were studied in the laboratory with wild fish
collected from a salmonid rearing stream. Control temperatures were similar to the temperature regime of a natural stream and the elevated temperatures were...
This thesis is the first third of a coming of age novel called i. In this selection the central character, Bea Bouvier, prepares to see her estranged mother on a cruise ship to the Bahamas. She hopes her parents will decide to reunite as a family, though it becomes increasingly...
The purpose of this study is to use an integrated biocultural perspective to examine the decision-making processes of young survivors as they navigate breast cancer treatment and reproductive health care options. This retrospective study utilizes a mixed-methods approach that integrates quantitative survey data (Phase I) with interview (Phase II) and...
This dissertation aims to provide a comprehensive portrayal of doula care in the lives of pregnant and parenting adolescent mothers. The purpose of this research was to examine the relationships between psychosocial stress, social support, institutionalized constraints, and their impacts on health and well-being among adolescent mothers in the Northwestern...
Because of competition from abroad, the U. S. Steel
industry has begun research into the processes involved
with electric arc steelmaking. This paper addresses the
mathematical background of these furnaces and the electro-magneto-
hydrodynamical effects used to melt the large
quantities of steel. A classical approach to the
derivation of...
The extensive and expanding use of radioactive materials
(RAM) in the production of power, industry, the healing
arts, and various branches of research has inevitably
resulted in a sizable increase of hazardous material
transportation in the state of Oregon. The location of the
Hanford facility just north of the Oregon...
The hydrophobicity of soils of the Deschutes National Forest was
studied. The soils are Cindery Typic Cryorthents, formed in cinders
and ash from Mt. Mazama. Ponderosa pine is the dominant overstory
vegetation. Of particular interest was the effect of prescribed
burning on hydrophobicity. Fire has been shown to cause a...
Nonlocal theories of continuum mechanics are used to model the
fracture behavior of particleboard in tension perpendicular to the plane
of the board. Classical theories of fracture are examined in comparison
to a nonlocal crack solution which has removed the stress singularity
at the crack tip. With the removal of...
INTRODUCTION:
Data on the safety of waterbirth in the United States are lacking.
METHODS:
We used data from the Midwives Alliance of North America Statistics Project, birth years 2004 to 2009. We compared outcomes of neonates born underwater waterbirth (n = 6534), neonates not born underwater nonwaterbirth (n = 10,290),...
Science inquiry is central to the science education reform efforts that began in the early 1990's. It is both a topic of instruction and a process to be experienced. Student engagement in the process of scientific inquiry was the focus of this study. The process of scientific inquiry can be...
Gaseous transport through soil in the presence of soil
microorganisms has been investigated. More recently, modeling of
gaseous transport in the unsaturated zone has been investigated.
However, the problem of mathematical model of oxygen and carbon
dioxide transport through soil, as affected by the climatic
conditions, the transport of soil...
Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...
This thesis is a work of literary non-fiction. It
is divided into six sections. The first, "A Sense of
Place," and the last, "Pulling a Geographical," are
collage essays which establish and then reiterate major
themes in the work: movement, work, geography,
climate, people, and education--some curricular, some
not. The...
The main focus of this study was to determine how community college
administrators used certain personality traits (cues) in judging the
success potential of female and male administrative applicants.
The following hypotheses were tested:
1. There will be no significant difference in the weights
attached to the following cues when...
This literature seeks to broadly examine historical literature and information pertaining to developmental education in the community colleges and its relationship with the college success. Contextually, the review will examine factors that affect student perception to academic success while being required to participate in remedial course work. Although issues surrounding...

This literature review seeks to broadly examine historical literature and
Freeze/thaw cycles are numerous in agricultural soils of the Pacific Northwest. Potential loss of soil by erosion is high whenever a soil thaws from the surface creating a saturated soil overlying an impermeable frozen layer. Field studies were conducted to investigate the effect of surface residue on soil freezing. Residue...
