Background: Medication complexity is a large determinant of adherence. Few studies have explored the relationship between cognitive impairment and medication complexity.
Objective: To evaluate whether cognitive impairment is associated with medication complexity for prescription and over-the-counter (OTC) medications.
Methods: In this cross-sectional analysis, we studied the association between cognitive impairment...
Between Oregon State University and DHBW Ravensberg, Global Formula Racing produces two Formula style vehicles every year for competition. This thesis has served as a pre-development project in the ergonomics and driver interface of the team's vehicles. This project will determine the position of the seat back, steering wheel, and...
A physical model study was performed to examine the forces and response of 1:6 scale wood-frame coastal residential structures subjected to storm surge and waves. An on-grade and an elevated specimen were tested and exposed to regular waves with varying water depths and wave heights to simulate Hurricane Sandy’s conditions....
As a way to improve safety and economics, one area of research and commercialization of new nuclear power plants has focused on the development of small modular reactors (SMRs). NuScale Power has developed a 50 MWe natural convection cooling SMR coupled with a regenerative Rankine cycle. Current estimates place the...
Chlorella is a genus of unicellular, enkaryotic green algae. Chlorella-like algae
are found as endocellular symbionts within a number of animal species. Two chloroplast
genes were sequenced from the exsymbiotic strain Chlorella N la, originally isolated
from Paramecium bursaria. The genes for the large subunit of ribulose-1,5-bisphosphate
carboxylase/oxygenase (rbcL) and...
The purpose of this thesis is to increase the positional accuracy of Global Position System (GPS) modules using an artificial intelligence algorithm. Three basic and identical GPS modules were setup in an equilateral triangle formation with side lengths of one meter. The triangle was placed in four separate locations where...
Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...
Knowledge of stand structure, stand dynamics, and production ecology of species mixtures lags well behind that of single-species, even-aged stands. Two mixed-species spacing trials in central Oregon allowed investigation of mixed-species dynamics in a controlled experimental setting. The first site, Pringle Butte, is a mixture of ponderosa pine (Pinus ponderosa...
The synthesis of isoindazoles bearing α-ketoester and α-hydroxyester groups via the coarctate cyclization of ester terminated azo-ene-yne precursors is described. Whereas previous studies on isoindazole formation have shown the reaction to proceed through a kinetic coarctate pathway, functionalization of the terminal acetylene with a methyl ester sufficiently stabilizes the carbene...
Capacity reduction programs in the form of buybacks or decommissioning programs have had relatively widespread application in fisheries in the US, Europe and Australia. A common criticism of such programs is that they remove the least efficient vessels first, resulting in an increase in average efficiency of the remaining fleet....
