The evolution of student understanding of the concept of derivative

Creator:: Zandieh, Michelle J.
Abstract:: This research seeks to answer the question, "What does it mean for a student to understand the concept of derivative?" A structured way to describe an individual student's understanding of derivative is developed and applied to analyzing the evolution of that understanding for each of nine high school seniors during...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:: Biel, Reuben G.
Abstract:: Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

High resolution spectroscopic studies of ³²S¹⁶O₃ and ³⁴S¹⁶O₃

Creator:: Barber, Jeffrey
Abstract:: The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...

Inelastic scattering of 17-MeV protons from ¹⁴N and ¹⁵N

Creator:: Rogers, Charles William
Abstract:: An inelastic scattering experiment was done in which 17-MeV protons from the Oregon State University cyclotron were scattered from ¹⁴N and ¹⁵N gas targets. Angular distributions are shown for the ground, 6.32-, 7.56-, 8.31-, and 8.57 -MeV states and the 5.3- and 7.2-MeV unresolved doublets of ¹⁵N, and for the...

Larval systematics of the Troginae in North America, with notes on biologies and life histories (Coleoptera: Scarabaeidae)

Creator:: Baker, Charles William, 1937-
Abstract:: A study of the immature stages of the subfamily Troginae in North America was conducted from the spring of 1963 through the spring of 1965, Larvae of Trox and Omorgus were easily reared in the laboratory, but all attempts to rear the larvae of Glaresis were unsuccessful, The suberosus group,...

Surface Modification to Enhance Corrosion Resistance of Carbon Steels using Additive Manufacturing

Creator:: Murkute, Pratik V.
Abstract:: Low carbon steels (LCS) due to their high strength-to-cost ratio are one of the most ubiquitous materials used for a wide range of applications, including but not limited to automotive, construction, and transportation. However, the low corrosion resistance of LCS in neutral, acidic, or saline environments limits its utilization and...

Malonaldehyde : certain chemical and biological properties

Creator:: Crawford, David Lee
Abstract:: Malonaldehyde, a three carbon dialdehyde, is one of the numerous carbonyl compounds associated with oxidative deterioration of food lipids. It is assumed to be formed as a product of lipid autoxidation occurring according to the generally accepted free radical mechanism. This compound is of great interest because of its potential...
