The Gd3+ ion has been used to induce quantum splitting in luminescent
materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum
splitting results from a two-step CRET between Gd3+ and Nd3+, first involving a
transition 6G→6I on Gd3+ and an excitation within the 4f3 configuration of Nd3+
followed by...
Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...
This research addressed the complexities of identity development in the lives of seven elementary and middle school preservice literacy teachers during their graduate teacher education program at a private western university using a poststructural feminism theoretical lens. This research investigated two questions: 1) How do preservice teachers develop their identity...
This project analyzes how women have radically changed the world of western print in the 21st century. To conduct this analysis, I examine a series of oral history interviews that I conducted in 2020 with women printers on the West Coast and employ a critical feminist methodology to study the...
The purpose of this study was to explore motivations behind participation in cosplay and the use of social media among cosplayers who maintain Facebook Artist Pages. Further focus was placed on investigating the role of Facebook Artist Pages in building fame. To explore such motivations, two theories were referenced: Deci...
Two strategic approaches to water quality control in Oregon's
Willamette River are presently being utilized: point source treatment
and flow augmentation. Dry weather releases from reservoirs are for
authorized purposes other than water quality. Reservoirs can participate
in pollution control by summer flow augmentation where authorized water
resource objectives (flood...
A high-spectral resolution laser-excited molecular fluorescence
system was developed that utilizes a pulsed supersonic expansion to
simplify the fluorescence excitation spectra of large, gas-phase
aromatic molecules diluted in an excess of a monatomic gas. A
microcomputer was used to control and synchronize the instrumental
components, which included a Chromatix CMX-4...
The purpose of this qualitative research study was to describe the experiences of secondary teachers who were actively involved in positions of teacher leadership in their schools and to discover the meaning that leadership activities had for them in their work. The informal teacher leaders performed their leadership functions in...
