Tsunami inundation of coastal communities can impose a wide array of forces on the
built environment. Forces generated by tsunami-driven debris damming have the potential to
cause failure of coastal structures and further accumulate flow-entrained debris. Since tsunami-resilient design standards were adopted by ASCE in 2016, debris damming considerations have...
There are about 80 million single-family dwellings (SFD) in the United States,
predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is
typically the largest single investment of a family, and is often not covered by earthquake
insurance, even where it is available. Of all the houses...
The absence of tsunami load provisions in coastal infrastructure design has led to unchecked resistance capacity of bridges against
one of the most eminent natural hazards on the U.S. west coast. The Spencer Creek Bridge, which was completely rebuilt on the Oregon coast in
2009, is a unique example to...
In the 1990s, Bartlett and Youd introduced empirical equations for predicting
horizontal displacement from liquefaction-induced lateral spreading; these equations have
become popular in engineering practice. The equations were developed by multilinear
regression (MLR) of lateral spreading case history data compiled by these researchers. In 2002,
these equations were revised and...
This paper presents a case study on the application of a dynamic framework for the intelligent
control of flooding in the Boise River system in Idaho. This framework couples a robust
and numerically efficient hydraulic routing approach with the popular multi-objective Non-dominated
Sorting Genetic Algorithm II (NSGA-II). The novelty of...
Bearing or compressive strength capacity perpendicular to the grain of timber beams is a troublesome issue. Not only do many different load cases occur in practice that are not covered by structural timber design codes but also these codes provide only a basic provision and vary throughout continents. Code design...
The nature of a natural antioxidant present in shrimp was
investigated.
Shrimp extracts were prepared using different solvents to
ascertain the best extraction method. The antioxidant activity was
determined using the (β-carotene-linoleate model system and the
oxygen weighing method. Ethanol proved to be the best solvent for
extracting the natural...
The effect of washing machine separated rockfish flesh on
composition, quality and desirability was investigated.
Washing machine separated rockfish flesh resulted in a
36.88% loss of solids. The greatest reductions were found in the ash
(80.32%) and lipid (65.13%) levels in the washed flesh. Most of the
sarcoplasmic proteins were...
The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...

In a paper now in press as a Bulletin of the U. S. Fish and Wildlife Services the writer has discussed the downward trend of the catch of Columbia River Chinook salmon since 1920 and has stated that the decline is doubtless an indication that the runs of this species...
By inverting EarthScope long-period magnetotelluric (MT) data from the southeastern United States (SEUS), we obtain electrical conductivity images that provides key insights into the geodynamics of this region. Significantly, we resolve a highly electrically resistive block that extends to mantle depths beneath the modern Piedmont and Coastal Plain physiographic provinces....

Let H be a cyclically-presented group on n generators with a single defining relator. Attempts have been made to classify such groups by their order, their status as a 3-manifold group, and the asphericity status of their presentations. For groups with a defining relator of length 3 these classifications are...
In the summer of 2009, a full-scale midrise wood-frame building was tested under a series of simulated earthquakes on the world's largest shake table in Miki City, Japan. The objective of this series of tests was to validate a performance-based seismic design approach by qualitatively and quantitatively examining the building's...
The objective of this project was to evaluate system effects and further define load paths within a light-frame wood structure under extreme wind events. The three-dimensional 30- by 40-ft (9.1- by 12.2-m) building, designed to be representative of typical light-frame wood construction in the southeastern coastal region of the United...

Investigations were conducted to (1) determine the original
pattern of deposition and thickness of ash in the Ochoco and Blue
Mountain areas of Oregon, (2) determine if discontinuities exist in
the parent material of these soils, (3) determine the degree of mixing
of ash with other materials and evaluate reworking...
The study of the question of why Shakespeare's Hamlet delays killing
Claudius in revenge for his father's murder is examined in light of the major
critical theories from neo-classical to modern scholarship. An expanded
treatment of the works of Fredson Bowers, Eleanor Prosser, Bertram Joseph,
and Roland Frye, is provided...
Oregon has the most extensive land-use planning program of any state in this country. Every acre of privately owned land in this state is zoned. Every acre is subject to a comprehensive plan. Planning affects the cost of your home, the distance you drive to work or shop, your property...

This study investigates the applicability of the database-assisted design (DAD) methodology to predict structural reactions in a light-framed wood structure subjected to fluctuating wind pressures. Structural influence functions were determined on a 1/3-scale light-frame wood structure, which was then subjected to a wind flow, while the surface pressures and structural...
