Analysis of semi-volatile trace metals in basaltic glass by LA-ICP-MS

Creator:: Loewen, Matthew W.
Abstract:: Semi-volatile trace metals (e.g., Cd, Sn, Pb, Zn, Cu, Mo) have been analyzed by using laser ablation ICP-MS in a number of silicate glasses (GSE-1G, GSD-1G, NIST 610, NIST 612, BCR-2G, BHVO-2G). Our work investigates and highlights sources of uncertainty in the analysis of semi-volatile metals using LA-ICP-MS. We identify...

Insights into the Geochemical Evolution of the Youngest Toba Tuff (Sumatra, Indonesia) Magma Chamber Through the Lens of Zircon-hosted Melt Inclusions

Creator:: Lerner, Allan
Abstract:: Supervolcanic eruptions are among the most catastrophic phenomena on Earth, erupting 100s-1000s of cubic kilometers of magma, and producing devastating local effects and global climate perturbations. The largest supervolcanic eruption of the last 28 Ma was the 74 ka Youngest Toba Tuff (YTT) eruption from Sumatra, Indonesia, which erupted 2,800...

A spatially explicit model for allocating conservation efforts : the Grand Ronde River basin, Oregon

Creator:: Watanabe, Michio
Abstract:: The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...

Investigation of Chain Extension Approaches for the Stereoselective Reagent-Controlled Synthesis of alpha-Heteroatom Substituted Alkyl Boronic Esters

Creator:: Barsamian, Adam L.
Abstract:: Two distinct strategies were explored for the enantioselective synthesis of α-heteroatom substituted alkyl boronic esters by stereoselective reagent-controlled homologation using transient chiral carbenoid reagents CHYMX (Y = heteroatom, X = nucleofuge, M = electrofuge). In the first case, a stereospecific reagent-controlled homologation (sStReCH) approach to α-alkoxyalkylboronates using α-metalated S,O- and...

Advection-diffusion in inertial flow through periodically converging-diverging tubes

Creator:: Lambert, Adam
Abstract:: A direct numerical simulation of advection-diffusion in a sinusoidal tube was carried out using the commercial ﬁnite-volume code STAR-CD. The Reynolds numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers, steady-state eddies formed in the diverging sections and significantly inﬂuenced the macroscale dispersion. Long...

Designing and creating the Oregon State age and disability simulation suit

Creator:: Rahrer, Adam P.
Abstract:: Over 54 million people report having disabilities in the United States. In addition, there are 40.3 million people 65 years and older living in America. As the population continues to live longer and problems with obesity continue to increase, the number of people with limited capabilities will escalate as well....

Analysis and modeling of single-ended and differential spiral inductors in silicon-based RFICs

Creator:: Watson, Adam C.
Abstract:: A new comprehensive wide-band compact modeling methodology for single-ended spiral inductors and differential spiral inductors is presented. The new modeling methodology creates an equivalent circuit model consisting of frequency-independent circuit elements for use in circuit simulators. A fast automated extraction procedure is developed for determining the circuit element values from...

The role of the homeodomain transcription factor Pitx2 in regulating skeletal muscle precursor migration and higher order muscle assembly

Creator:: Campbell, Adam L.
Abstract:: Cells of the ventrolateral dermomyotome delaminate and migrate into the limb buds where they give rise to all muscles of the limbs. The migratory cells proliferate and form myoblasts, which withdraw from the cell cycle to become terminally differentiated myocytes. The regulatory mechanisms that control the later steps of this...

STEM Partnerships: Drawing on Historicity to Negotiate Tensions in Engagement

Creator:: Talamantes, Adam C.
Abstract:: This qualitative study examines how FIESTAS (Family Involved in Education, Sociocultural Teaching and STEM) partners (comprised of out-of-school time (OST) educators, university student STEM instructors, and local business representatives) came together to facilitate a local STEM Club located in two dual-immersion elementary schools in the Pacific Northwest. The study addresses...

Essays on natural endowments, conservation policy, and community characteristics

Creator:: Lin, Haixia
Abstract:: To protect and restore environmental quality, efficient and effective conservation policies are needed. Designing policies require a sound understanding of the contributions of natural endowments to economic vitality, and the performance and impacts of conservation programs. This dissertation consists of three essays, and addresses several issues relevant to these two...
