Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

Creator:: Kimbrel, Jeffrey A.
Abstract:: Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...

The effects of engineered coatings and natural organic matter on nanoparticle aggregation

Creator:: McDowell, Shannon A.
Abstract:: In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

A macroscale measurement and modeling approach to improve understanding of the hydrology of steep, forested hillslopes

Creator:: Graham, Christopher Brian
Abstract:: The dominant controls on flow generation in steep, forested hillslopes are poorly understood. This dissertation examined the dominant flow processes operating at the hillslope scale, using a combined macroscale measurement and model development and analysis framework. Irrigation experiments at two steep forested hillslopes were conducted to isolate individual hillslope flow...

Developing a Standard to Assess Water Repellency and Dimensional Stability of Preservative Treated Railroad Ties or Other Large Timbers

Creator:: Trebelhorn, Daniel B.
Abstract:: Untreated wood is inherently hygroscopic and moisture content variations can have substantial effects on dimensional stability leading to the development of deep surface checks that further enhance moisture uptake and ultimately encourage deterioration. The horizontal exposure of wood crossties makes water repellency and dimensional stability particularly important in railroad applications....

Construct validation of self-report with assistance to measure physical activity behavior in adults with intellectual disabilities

Creator:: Johnson, Marquell J.
Abstract:: The purpose of this study was to examine the evidence of construct validity for self-report with assistance from a secondary source as a measure of physical activity (PA) in adults with intellectual disabilities (ID) in free-living environments. Thirty-seven participants (21 females, 16 males) with mild to moderate ID aged 19-74...

Participation of adults with mental retardation in a voluntary physical activity program

Creator:: Stanish, Heidi Isabel
Abstract:: This study compared the effect of two sources of instruction and verbal encouragement on the participation of individuals with mental retardation (MR) in a 10-week physical activity program. Participants were 17 adult employees of a sheltered workshop (5 females, 12 males) ranging in age from 30 to 65 years. The...

The effectiveness of a static and dynamic balance training program for children with cerebral palsy

Creator:: Senisi, Michael
Abstract:: Balance is the ability to establish an equilibrium between the body and its environment. Balance is a key component which is associated with a variety of movements and postural control. Children with cerebral palsy (CP) have difficulties with movement and postural control due to physical and neurological limitations. The purpose...

A comparison of bone mineral density between active and nonactive men with spinal cord injuries

Creator:: Eddins, William C.
Abstract:: The purpose of this study was to compare the levels of bone mineral density (BMD) of the whole body (WB) and proximal femurs of physically active men with spinal cord injuries (SCI) to nonactive men with spinal cord injuries. Also, the lean muscle mass (LMM) of active men with SCI...

Effects of a resistance exercise program on activities of daily living of elderly women

Creator:: DeVries, Christine L.
Abstract:: The purpose of this study was to determine if a 5-month progressive-resistance exercise program would affect measures of activities of daily living (ADLs) and functional stability in elderly women. All subjects were ambulatory women, 80 to 93 years old, who lived in assisted-care facilities. Eight exercise and 7 control subjects...
