A mathematical model is developed for the analysis of circular
cell bulkheads subjected to gravity loads of cell fill, backfill, lateral
pressure, and surcharge load using the finite element method. The
finite element circular cell model consists of axisymmetric triangular
and/or quadrilateral ring elements for soil and cylindrical shell elements...

No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...

A single cell in a 12 cell bulkhead was instrumented to observe
its behavior and confirm design assumptions during construction.
Vibrating wire strain gages were employed to measure horizontal
strains in sheetpiling webs. These were converted to interlock

The circular wave basin provides a means of physically modeling the nearshore
without the typical problems associated with end walls. Three different coastal
processes were examined to demonstrate the use of a spiral wavemaker in a circular
wave basin. These were longshore currents, shear waves, and groin circulation. A
beach...
Independent systems theory has been used to interpret the
circular dichroism (CD) spectra in the vacuum uv of three cyclic
dimers of amino acids. First, the theory for rotational strengths is
developed in terms of degenerate and nondegenerate group functions.
All terms to first order in perturbation theory are kept....

Friction factors were measured for water flowing in ducts made
up of two rods held between two flat plates. Three rod diameters of
0.50, 1.00 and 1.50 inches were used. The spacings between rods
varied from 0.0 to 0.32 inch. It was found that the concept of
hydraulic diameter was...
Circular dichroism (CD) spectra were obtained for bacteriophage T4 lysozyme and three of its mutants in the presence and absence of colloidal silica nanoparticles. Mutant lysozymes were produced by substitution of the isoleucine at position 3 with tryptophan, cysteine and leucine. Each substitution resulted in an altered structural stability, quantified...

This publication covers log loading and transportation, including landing organization, road conditions, equipment, and costs. It also treats special concerns for woodland owners.
Carpenter ants are serious pests of buildings in Oregon, particularly west of the Cascade Mountains. Although they normally excavate in logs, stumps, and hollow trees, these ants become pests when they move indoors.
Some grandparents whose grandchildren live far away are concerned
that they might be missing out on their grandchildren’s everyday
lives and special experiences. But living
far apart doesn’t mean you can’t be close
emotionally. Long-distance grandparenting is a challenge,
yet with careful planning you can be in touch
with your...
Not only does the publication of Ovidian adaptations online increase public awareness of Ovid, but it also offers new material for research and pedagogical purposes. Consequently, in this thesis, I explore both the historical tradition of Ovidian adaptations, specifically adaptations of Ovid's Orpheus tale, and the modern presentation of Ovidian...
This publication describes measurements used to buy and sell timber products. Managing woodland property offers you the opportunity to harvest a variety of products, depending on timber quality and quantity, harvest economics, and market availability. Among these products are saw logs, peeler logs, pulpwood, fuelwood, poles, piling, and posts. Knowledge...

Two types of linear random wave simulation methods are investigated;
viz., (1) Deterministic Spectral Amplitude (DSA) and (2) Nondeterministic
Spectral Amplitude (NSA). These linear simulations are extended to
second-order in a perturbation expansion in the frequency domain by
utilizing a Fast Fourier Transform (FFT).
The nonlinear interaction matrix for waves...
Remediation methods and strength predictions were evaluated for wood I-joists with single, circular holes in the webs, leaving utilities in place. A full-scale bending test using four equally-spaced point loads was applied to three depths of joists with varying flange widths and span lengths of 4.88 m and 2.44 m....
The objective of this project was to evaluate methods to remediate a wood I-joist with a single, circular hole in the web while leaving utilities in place. The methods were experimentally evaluated with a full-scale bending test using four equally spaced point loads. There were three depths of joists with...
The circular dichroism spectra of amylose, the maltose
oligomers, cellobiose, and the cycloamyloses are measured in
aqueous solution to 1640 A. Two bands are found in this region. The
long wavelength band is assigned to the ether chromophores; the short
wavelength band is assigned to the hydroxyls and further ether...

A model for analytical study of the attitude stability of an
orbiting satellite consists of a rigid body whose mass center is constrained to move at constant speed in a circular path about the
center of an inverse-square force field. The body is assumed to

The asymptotic boundary layer problem involving an axial
incompressible Newtonian fluid flow past a circular cylinder parallel
to its axis was investigated by Stewartson (1955). He addressed hiself
primarily to the Mangler's (1948) derivation, namely, the
character of the boundary layer on a circular cylinder is equivalent to
that on...
An experimental study was conducted to determine the hydrodynamic
forces on smooth and roughened circular cylinders as
influenced by a nearby plane boundary. The ambient flow was perpendicular
to the cylinder and parallel to the boundary. Measurements
were taken in a water channel and a wind tunnel to obtain the...
Equipment for strip-till planting is under development in wheat-fallow
rotations in the Columbia Basin of Oregon. This involves the
absence of tillage during the fallow season. At planting time, the
strip-till planter creates a narrow band into which the wheat seed is
placed. The area between the rows is undisturbed...
An investigation was made to test the method of Head on the
flow about a circular cylinder with suction. The method of Head is an
approximate method of obtaining solutions to the boundary layer equations.
The method was adapted to the digital computer to facilitate
performing the calculations, and a...
This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...
