Tidal influence on downstream fining in gravel-bed rivers

Creator:: Coles, Derron Rafiq
Abstract:: This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

Modeling protein structure at atomic resolution

Creator:: Berkholz, Donald S.
Abstract:: This thesis includes three studies involving different aspects of modeling protein structure. The first study illustrates the levels of insight available from atomic-resolution protein structures. The second study derives general trends of protein geometry from atomic-resolution structures and shows their implications for modeling. The third study creates a model of...

Canopy Ecology of Swiss Needle Cast in Young and Mature/Old-growth Douglas-fir (Pseudotsuga menziesii)

Creator:: Lan, Yung-Hsiang
Abstract:: Swiss needle cast (SNC) is a foliage disease of Douglas-fir caused by Nothophaeocryptopus gaeumannii, an Ascomycete fungus (Mycosphaerellaceae) that causes growth reductions in Douglas-fir plantations across the Pacific Northwest. Epidemiology of the fungus is generally well known in plantation trees, but the relationship between disease expression and foliage nutrition and...

Regulation of skeletal muscle protein degradation by u-calpain and development of a skeletal muscle-specific inducible expression system

Creator:: Xiao, Ying-Yi
Abstract:: The first goal of this study was to understand the role of u-calpain in skeletal muscle protein degradation in cultured muscle cells. Several strategies were developed to down-regulate endogenous u-calpain activity and m-calpain activity in rat myotubes. These included over-expression of antisense u-calpain (AnsL), dominant negative u-calpain (DN-u-CL), antisense 30K...

Gene Networks of the Skeletal Muscle Cell

Creator:: Singh, Arun J.
Abstract:: Skeletal muscle is the largest organ in the body by mass, comprising roughly 40% of total bodyweight in adults. It plays diverse and unique roles that include movement, locomotion, and support for posture and internal organs, among others. The structural foundation for all skeletal muscle in adults is formed early...

Oxidative stress and muscle dysfunction following anterior cruciate ligament surgery

Creator:: Barker, Tyler
Abstract:: Despite the advances in surgery, physical therapy, and pharmaceutical agents, muscle dysfunction (i.e., atrophy and weakness) continues to impair recovery from an anterior cruciate ligament (ACL) injury and surgery. Ischemia-reperfusion injury during surgery and the subsequent limb disuse are two events experienced by patients having ACL surgery. Oxidative stress and...

Quorum-sensing-controlled public goods in Pseudomonas aeruginosa : regulation and application

Creator:: Mellbye, Brett L.
Abstract:: Cell-to-cell communication by chemical signals, termed quorum sensing (QS), is a common regulatory scheme in the microbial world. Pseudomonas aeruginosa¸ an opportunistic pathogen of burn wounds and cystic fibrosis lungs, uses QS to control the expression of hundreds of genes, particularly those necessary for population level benefits such as biofilm...

Microbial and biochemical dynamics of ectomycorrhizal mat and non-mat forest soils

Creator:: Kluber, Laurel A.
Abstract:: Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...

Alternative splicing in the obligate biotrophic oomycete pathogen, Pseudoperonospora cubensis

Creator:: Cumbie, Jason S.
Abstract:: Oomycetes are some of the most devastating pathogens, causing upwards of billions of dollars of damage each year to plants. They also diminish ecological diversity and health through the destruction of trees and shrubs. The genome sequence of Pseudoperonospora cubensis, an obligate plant pathogen and causative agent of downy mildew...

Evaluation of Driver Behavior during Right Turn Maneuvers at Signalized Intersections: Mitigation of Driver-Pedestrian Conflicts with a Right Turn Flashing Yellow Arrow

Creator:: Jashami, Hisham
Abstract:: Accommodating motor vehicles that are turning (left or right) at signalized intersections requires a careful understanding of the safety and efficiency of design and operational variables. Turning vehicles are the primary collision risk for non-motorized road users at signalized intersections. When turning movements need to be controlled, proper driver response...
