Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...
Functional programming is concerned with referential transparency, that is, given a certain function and its parameter, that the result will always be the same. However, it seems that this is violated in applications involving uncertainty, such as rolling a dice. This thesis defines the background of probabilistic programming and domain-specific...
In forest trees from temperate and boreal regions, cold acclimation is an important
adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...
Two studies used DNA markers to assess their usefulness in germplasm identification and evaluation of genetic stability in four cryopreserved Rubus accessions that were stored for over 10 years in liquid nitrogen. In the first study, 12 robust Simple Sequence Repeat (SSR) markers were developed from two microsatellite-enriched libraries of...
Standard methods of measuring fecal pollution in water do not distinguish between human and non-human sources. Molecular technology enabled the development of host-specific markers that distinguish fecal sources. Human specific PCR primers, HF183F and HF134F, were designed based on phylogenetic analyses of partial 16S rRNA gene sequences from the Bacteroidales...
Biocompatible hydrogels composed of covalently crosslinked, chemically modified hyaluronan (HA), gelatin (Gtn), and heparin (Hp) were synthesized for controlled release of human vascular endothelial growth factor (VEGF) or basic fibroblast growth factor (bFGF). We hypothesized that inclusion of small quantities of heparin in these gels would result in regulated growth...
Glucose was gasified in supercritical water within a microchannel reactor at 650°C 750°C, and 250 bar to yield H2 rich gas with a low concentration of CO. The feed glucose concentration was 0.1 M. Two microchannel reactor configurations were tested at fluid residence times ranging from 0.5 sec to...
Oregon's estuarine wetland landscapes have been changed, especially since the nineteenth century, by diking, dredging, fills, and other alterations. These alterations have removed wetlands from the estuaries, and with them, have removed wetland functions. Currently, efforts are being made to restore estuarine wetlands. The first step in
selecting a site...
The isoprenoid pathway is one of the major biosynthetic pathways of secondary metabolites. Isoprenoids with a C₂₀ skeleton are known as diterpenoids and are derived from the common precursor, geranylgeranyl diphosphate (GGPP). This dissertation describes approaches to discover the diterpene synthase enzymes which provide the backbone structures for pleuromutilin and...
Two experiments were conducted looking at both acute and sub-acute laminitis. An acute nutritional induction model was used to examine whether blood profiles and gene expression are similar to other studies conducted using an endotoxin induction model. Twelve sheep were randomly assigned to three treatment groups which were control, 4-hour...
