The late holocene atmospheric methane budget reconstructed from ice cores

Creator:: Mitchell, Logan E.
Abstract:: Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...

Towards a Better Understanding of How the Dietary Supplement Xanthohumol Can Improve Health

Creator:: Logan, Isabelle E.
Abstract:: Xanthohumol, a prenylated flavonoid found in hops and beer, possesses a long-standing reputation to improve health. Xanthohumol’s cytotoxicity to a wide variety of cancer cell lines is well-established. Herein we provide further insight into the cytotoxicity of not only xanthohumol, but also its non-estrogenic derivatives, to a number of colonic...

Some factors affecting absorption and translocation of phenoxyalkylcarboxylic acids in plants

Creator:: Norris, Logan A. (Logan Allen)
Abstract:: Studies were conducted to determine the influence of formulation and molecular configuration of some chlorinated-phenoxyalkylcarboxylic acid herbicides on their absorption, translocation and metabolism in bigleaf maple, Acer macrophyllum, Pursh. Five to eight year old bigleaf maple seedlings were treated with one percent solutions of carbon 14-labeled herbicids. After three days...

Alcohol use, knowledge and attitudes among freshman women

Creator:: Hazen, Logan Rhodes
Abstract:: The purpose of this study was to investigate the influence of alcohol on freshman women during the critical transition into college. Specifically, the study focused on differences in knowledge of alcohol facts and attitudes toward use of alcohol among freshman women prior to college. Further, the study focused on changes...

Physical Activity Promotion for Emerging Adults with Intellectual and Developmental Disabilities Transitioning from High School into the Community: A Virtual Intervention Grounded in Self-Determination Theory

Creator:: Raja Vora, Joseline
Abstract:: People with intellectual and developmental disabilities (IDD) engage in lesser physical activity (PA) and more time in sedentary activities as compared to those without disabilities. A subset of people with IDD who are most vulnerable to develop habits detrimental to health is the emerging adults who are transitioning from adolescence...

Target Value Uncertainty and Goodwill Impairment: Public & Private Targets

Creator:: Mikus, Brad
Abstract:: In this study, I investigate how target value uncertainty may lead to acquirer mispricing of an acquisition target and how the mispricing may be a determinant of goodwill impairment. To the extent the mispricing leads to both high and low industry-adjusted purchase price multiples (PPMs are my proxies for overpayment...

Forest Response to Water Availability and Disturbance in the Western United States

Creator:: Berner, Logan T.
Abstract:: Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...

Nitrate and Nitrite Differentially Affect Respiration in Zebrafish During Exercise

Creator:: Logan, Christiana R.
Abstract:: A decline in the oxygen cost of exercise enhances exercise tolerance and performance. Substantial research has shown that dietary nitrate lowers the oxygen cost of exercise in sedentary humans; however, the metabolic determinants regarding how dietary nitrate influences oxygen consumption in skeletal muscle is not known. We addressed this gap...

C-SHIFT, Quantile Theory, and Assessing Monotonicity

Creator:: Logan, Paul R.
Abstract:: DNA microarray technology is a powerful tool for analyzing patterns in gene expression data for thousands of genes. Due to a number of systematic variations in microarray experiments, the raw gene expression data is often obfuscated by undesirable technical noises. Various normalization techniques were designed in an attempt to remove...

Full-Scale Experimental Investigation of the Seismic Capacity of Reinforced Concrete Column-Footing Specimens Retrofitted with Titanium Alloy Bars Considering Effects of Soil-Structure Interaction on Vintage and Retrofitted Column-Footing Specimens

Creator:: McGinn, Logan
Abstract:: Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...
