In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...
Modern science was produced by a Christian society,
and although science has had an effect on Christianity, it
could not itself remain unaffected. In the second half of
the nineteenth century, the subject of evolution was as
much a religious as a scientific issue. The battle line
was drawn and...
Fort Hoskins is located near Kings Valley, approximately 16 miles from
Corvallis. The Fort, built after the Rogue Wars of the 1850s, was intended to safeguard
the newly created Indian reserves. During its' ten-years of existence, U.S. Army
Regulars manned the Fort from 1856-1861 while volunteers from California,
Washington, and...
The purpose of this investigation was to locate, organize and
analyze information pertaining to clothing and household textiles of
Aurora Colony, Oregon, which existed from 185 7 to 1877. Aurora
Colony was a communal group, headed by Dr. William Kiel, which
emigrated from Bethel, Missouri to Oregon in 1857. This...
This thesis is a collection of essays about Paxton, a
small town in western Nebraska, and an exploration of the
contradictions and complexities found there. It is also a
reflection on the layers of history and connections that
exist not only among families that have lived in these towns
for...
This dissertation outlines the design and development of the first fully-soft, snake robot and its snake-inspired skin. Soft robotics takes advantage of soft materials to, among other things, improve robot interactions with complex, unstructured environments. Due to the interplay between the soft material and the environment, minor tweaks to the...
The fluid impact forces on a bridge superstructure in horizontal and vertical directions due to tsunamis represented by solitary waves are investigated through a large-scale laboratory experiment and numerical simulations. The experiment is conducted in a two-dimensional wave basin using a 1:5 scaled reinforced concrete bridge deck model tested under...
During the eighteenth century, diagrams increasingly became an important aspect of scientific inquiry. Diagrams employed simplification as a strategy for representing complex information, played a role in standardizing scientific language, and served as instruments of reason to think through and communicate problems and findings in mathematics, physics, chemistry, astronomy, natural...
Situated cognition theory emphasizes the role that social and material contexts have on learning and knowledge application. Several studies of engineering workplace environments have noted differences between the social and material contexts of the workplace and those of undergraduate engineering education. No existing research has studied the social and material...

The Wheat Growers Economic Conference was called in order to formulate a program for agriculture in the Columbia River Basin. Many ideas have been advanced by many people trying to help and stabilize agricultural conditions there. These ideas have varied widely, some being directly opposed to others. The proposals and...
During the early 19th Century, the fur trade brought many Iroquois to the Pacific Northwest as working primarily as voyageurs for the North West Company. When the North West Company merged with the Hudson's Bay Company, the Iroquois employees merged as well. After retirement, some settled in the Willamette Valley...
Ideals of freedom, independence, and land ownership helped form and perpetuate the mythology of ranching in the United States. However, stereotypes emerged as a result of distortion from the media and the move away from the land. Social philosophies changed
regarding the environment, land use, and the health and safety...
Champoeg, located along the Willamette River, developed
as a transportation center for both river and overland
travel and as a shipping point for agricultural products.
Retired employees of the Hudson's Bay Company were the first
to settle in the area, in the 1830s. American settlers
began arriving in large numbers...
Nowadays selective separation processes are sought after more than ever before. They are indispensable to meet the growing demand for individual rare earth elements, minor actinides partitioned from fission-produced lanthanides, as well as, overall, more concentrated and high-purity products. This research focuses on such separation techniques as solvent extraction which...
The Salt Range and Potwar Plateau are part of the currently active
foreland fold-thrust belt of the Himalaya in Pakistan. Seismic reflection data have been combined with surface mapping, drillhole and
paleomagnetic information to construct balanced structural cross-sections of the current frontal thrust zone (Salt Range), and to estimate
the...
There are many existing bridges around the world that were designed without consideration for seismic effects. Many of these bridges were designed before modern earthquake engineering design standards and practices existed and thus are expected to perform poorly during strong ground shaking. Common structural deficiencies are found in their reinforced...
Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...

The majority of low-rise residential structures in the U.S. are constructed with wood. Wood-based composites are primary building materials in these structures, used as structural sheathing, joists, and beam components. Wood composites are susceptible to degradation upon exposure to high levels of moisture. Moisture durability is routinely assessed with accelerated...
John Wesley Powell worked actively for public land system
reform while a director of geographical and geological surveys in
the West from 1869 to 1894. Although this has won him acclaim as a
conservationist, the basis of Powell's linkage of reform with
scientific work is poorly understood.
A study of...
