Supervised exercise interventions can elicit numerous positive health outcomes in
breast cancer survivors. However, to maintain these benefits, exercise needs to
continue long after the supervised program. This may be difficult, as in this
transitional period (i.e., time period immediately following a supervised exercise
program), breast cancer survivors are in...
Many D2d-symmetric 2,2',6,6'-tetrasubstituted biphenyls are
readily prepared via net oxidative dimerization of appropriate
1,3-disubstituted benzenes. Conversion of such proprochiral
compounds to useful C2-symmetric chiral biphenyls requires
formal replacement of two substituents on opposing aryl ring
units with alternate groups. This under exploited
desymmetrization tactic has been demonstrated for the
generation...
Unpaved roads are a critical form of infrastructure in forested landscapes but also a potential source of fine sediment that can degrade sensitive ecosystems nearby. Improved management of aggregate road surfacing can reduce sediment generation, lengthen its useful life span, reduce maintenance costs, and more importantly, mitigate the impacts of...
A cultural landscape analysis of two historic cemeteries in St. Paul, Oregon demonstrates that the residents of this early community were unknowingly using grave markers to express their worldview and the identities that they felt were most important. Because of the historical and cultural development of this community as the...

In this thesis I explore the ways in which twenty-first century Americans have access
to Geoffrey Chaucer and his works. I look at issues surrounding Chaucer within the
canon debate, high school history and literature textbooks, and Chaucer in popular
culture, such as in movies like A Knight's Tale. I...
Nonnegative matrices have a myriad of applications in the biological, social, and physical genres. Of particular importance are the primitive matrices. A nonnegative matrix, M, is primitive exactly when there is a positive integer, k, such that M[superscript k] has only positive entries; that is, all the entries in M[superscript...
7,7'-Dihydroxy-8,8'-biquinolyl (azaBINOL) was prepared from 7-hydroxyquinoline via N,N-dimethyl O-quinol-7-yl carbamate by directed ortho-metallation followed by FeCl₃-mediated oxidative coupling of the 8-lithioquinoline intermediate. Saponification of the resulting dicarbamate provided crystalline (±)-azaBINOL in 56% overall yield. 6,6'-Bis(dimethylaminocarbonyl)-7,7'-dihydroxy-8,8´-biquinolyl was prepared from the same dicarbamate by a double anionic-Fries rearrangement in 43% yield. 7,7'-Bis(diethylamino-carbonyloxy)-6,6'-diiodo-8,8´-biquinolyl...
Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...
Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...
In 1986, researchers from Oregon State University, led by Dr. David Brauner, came to the small Catholic community of St. Paul, Oregon as part of ongoing research on the French-Canadian inhabitants of the Willamette Valley between 1829 and the mid-1860s. They were searching for the remains of the first Catholic...
Current evidence suggests that temporal regulation of gene
expression in eucaryotic organisms relies primarily upon localized
structural modifications of chromatin. One possible means of
changing chromatin structure is through varying the level of
acetylation of the histone proteins. Sodium butyrate has been found
to inhibit the activity of histone deacetylase...
Heavy mineral compositions of sands from Oregon beaches,
rivers and sea cliffs have been determined in order to examine the

It provides a model to investigate coastal erosion associated with sea-level rise. The natural water...
During the period 1970-76, Siletz Spit on the mid-Oregon coast
has suffered foredune erosion. This erosion is associated with high
wave conditions along the coast, produced by intense storms in the
North Pacific.
During the winter of 1972-73 and during January through March
1976 the erosion was particularly severe. The...
Two beaches with significant differences in grain size and thus in beach profile morphology and response to wave conditions were studied on the Oregon coast. Gleneden Beach, just south of Siletz Spit and Lincoln City, has a median grain size of 0.36 mm (medium sand) and a steep beach face...
Straight, radial, erosional channels and fan-like deposits of tephra develop around steep-sided cones and composite volcanoes, but are not characteristic features of shield volcanoes. The channels and deposits normally are formed by explosive volcanic density currents which originate as nuées adrentes or base surges. The physical processes of explosive volcanic...
Theoretical breaking criteria for progressive surface gravity
waves are examined, and laboratory and field experiments concerned

School forests in South Korea are trees and vegetation areas within schoolyards, and they provide natural environments for schools and neighborhoods. After the Korea Forest Service (KFS) and local governments create these school forests, the management of school forests transfers to the host schools. Some studies suggest that experiences with...
Siletz Bay is a drowned river valley filled with Holocene alluvial
and estuarine sediments and is separated from the ocean by a sand
spit 3.8 km in length. Since the area was settled by white man in the
1890's, the bay has apparently experienced rapid siltation, due to
increased farming...
The formation of beach placers primarily involves processes of
waves and currents that selectively sort and concentrate the valuable
minerals according to their densities, sizes and shapes. Black sand
placers are found on the beaches adjacent to the mouth of the Columbia
River. Reviews of historical shoreline changes show that...
Grain-size distributions of gravels transported as bedload in Oak Creek, Oregon,
show systematic variations with changing flow discharges. At low discharges the gravel
distributions are nearly symmetrical and Gaussian. As discharges increase, the
distributions become more skewed and follow the ideal Rosin distribution. The patterns of
variations are established by...
Sea-cliff erosion is a significant problem along the Oregon coast in that many
communities have been built on terraces affected by bluff retreat. There is considerable
coast-wide variability in the rates of cliff erosion. This variability is attributed in part to
tectonic activity that is causing differential interseismic uplift along...

A graph may he drawn in many different ways. We investigate how to draw a graph nicely, in the sense of being visually pleasing. We discuss the history of this field, and look at several algorithms for drawing graphs.
For planar graphs this problem has been algorithmically solved: that is,...
Sequential machines uniquely determine directed graphs. A path in a sequential machine may be specified by a starting state and an input sequence. A uniform Hamiltonian touring sequence (UHTS) is an input sequence that specifies a Hamiltonian path regardless of the starting state. We present a polynomial time algorithm that...
Why are the fast Fourier transform and the fast
Hadamard transform fast? A transform can be computed by
multiplying a matrix times a vector, which normally requires 0(n²) operations. The matrices corresponding to
these transforms can be rearranged to eliminate redundant
computations resulting in O(nlogn) operations.
We investigate algebraic reasons...
Sulfoxide-ligand exchange (SLE) and asymmetric halogen-metal exchange (AHME) processes were separately examined for the enantioselective synthesis of functionalized alpha-haloalkylmetal (carbenoid) reagents. Carbenoids derived from SLE were used to effect stereospecific reagent-controlled homologation (StReCH) of boronic esters and those generated via AHME were engaged in Darzens-type chemistry with aldehydes.
Abstract for...
Polyhedra are geometric representations of linear systems of equations and
inequalities. Since polyhedra are used to represent the iteration domains of nested
loop programs, procedures for operating on polyhedra can be used for doing loop
transformations and other program restructuring transformations which are needed
in parallelizing compilers. Thus a need...
Members of the deltocephaline leafhopper genus Giprus Oman
live on grasses, primarily in the desert-scrub, chaparral, and
marine sand dune communities of western North America. Of 16
known species, 10 are undescribed. Recharacterization of the genus
results in exclusion of Laevicephalus incongruus Oman. Differentiation
of species is primarily dependent on...
Most measures of program complexity gauge either textual or
control flow attributes of a program. A recent addition to the field
of complexity measures, the knot metric, is a function of both these
attributes. A knot measurement reflects the degree of control-flow
