Lignin-Derived Thermosetting Vinyl Ester Resins For High Performance Applications, Daniel Rogers

Theses and Dissertations

Vinyl ester (VE) resins are utilized to produce polymer matrix composites for use in a wide range of applications due to possessing relatively high moduli, strengths, and glass transition temperatures while maintaining low weight and cost. VE resins often contain high concentrations of a petroleum-based reactive diluent (RD), such as styrene. Many of the commonly used RDs have been designated as hazardous air pollutants, potential carcinogens, and volatile organic compounds. Renewable VE resins and RDs with similar performance to petroleum-based RDs are desired to potentially mitigate the aforementioned hazards as well as to facilitate the transition from petrochemical feedstocks to …

Energy Dissipation And Constitutive Modeling For A Mechanistic Description Of Pad Scratching In Chemical-Mechanical Planarization, David Ponte, D.M.L. Meyer

Mechanical, Industrial & Systems Engineering Faculty Publications

A thermomechanical model to describe the mechanisms of polishing pad scratching in chemical–mechanical planarization (CMP) has been formulated and investigated. CMP is a necessary process in integrated circuit (IC) fabrication to planarize wafers with nanoscale features after patterned layer deposition. Polishing pad asperities can produce microscale scratches on the wafer surface during CMP, reducing IC manufacturing yields. The constructed thermomechanical model accounts for stresses of the pad and wafer contact and also provides the means to track input energy dissipation during CMP. Tracking energy dissipation offers information about processes that may influence scratch production. This knowledge ultimately produces a greater …

The Corpus Callosum In Primates: Processing Speed Of Axons And The Evolution Of Hemispheric Asymmetry, Kimberley A. Phillips, Cheryl D. Stimpson, J. B. Smaers, Mary Ann Raghanti, B. Jacobs, A. Popratiloff, Patrick R. Hof, Chet C. Sherwood

Psychology Faculty Research

Interhemispheric communication may be constrained as brain size increases because of transmission delays in action potentials over the length of axons. Although one might expect larger brains to have progressively thicker axons to compensate, spatial packing is a limiting factor. Axon size distributions within the primate corpus callosum (CC) may provide insights into how these demands affect conduction velocity. We used electron microscopy to explore phylogenetic variation in myelinated axon density and diameter of the CC from 14 different anthropoid primate species, including humans. The majority of axons were less than 1 µm in diameter across all species, indicating that …

“Adulthood” By Whose Definition?: The Complexity Of Emerging Adults’ Conceptions Of Adulthood, Larry J. Nelson, Stephanie S. Luster

Faculty Publications

The beginning of adulthood may well be the most nebulous transition of the life course. It is fair to say that no clear-cut universal marker indicates the beginning of adulthood, leading to widespread cultural and individual diversity in the beliefs of you people aged 18–29 regarding what it means to be an adult and how the transition into adulthood should occur. This chapter examines this complexity. The authors review the literature exploring the conceptions of adulthood of young people begging at age 18 and continuing through the third decade; examining how these conceptions have been linked to beliefs, behaviors, and …

Principal Leadership Practices In High Poverty K-5 Model Schools In Oregon, Janice Marie Adams

Dissertations and Theses

Children living in poverty in the United States face some of life's greatest challenges, including achieving academic success in school. Evidence is also emerging of a growing income disparity in America that affects families, communities and local labor markets in ways that can undermine the effectiveness of schools serving disadvantaged populations (Duncan & Murnane, 2011). Evidence exists, however, that high academic performance is within the reach of all children in high poverty schools, and that principal leadership is a contributing factor.

This study examined principal leadership practices in three high poverty K-5 elementary schools in Oregon identified as Model schools …
