Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleterious effects for calcifiers, but responses vary greatly across taxa and can be influenced by variations in other environmental characteristics. Scaling...
Respiratory infections caused by nontuberculous mycobacteria (NTM), especially Mycobacterium avium, can lead to progressive, recurrent disease that is refractory to therapy. Bacterial biofilms are intrinsically resistant to a variety of stressors and pressures, including host killing mechanisms and antibiotic therapy. Though it is becoming increasingly evident that NTM biofilms are...
Individuals with Senile Dementia of the Alzheimer Type (SDAT) are up to four times more likely to sustain an accidental fall than their non-demented peers. The cause(s) of this elevated risk, however, has not been determined. Prior to the design of balance retraining programs, researchers need to uncover the nature...
Three studies were conducted to characterize and present early-seral
competition between Douglas-fir seedlings and the surrounding vegetation
communities during Pacific Northwest forest establishment. The first experiment
served as the foundation for this dissertation and was designed to quantify tradeoffs
associated with delaying forest establishment activities by introducing a fallow year...
Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching,
and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...
Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...

The back thrust kick is a karate technique used primarily in a
defensive setting. This research described the kinematic
variables involved in the skilled execution of the kick. Variables
examined included movement sequencing, angular position of
the trunk, thigh and leg, angular velocity of the thigh and leg,
linear velocity...
This study investigated the influence of perceptual training on
volleyball serve-reception performance. The subjects were ten female high-school
volleyball players. Subjects were randomly assigned in equal
numbers to a control or an experimental group.
Both groups were tested on two occasions, prior to and following a
three-week perceptual training intervention....
The phenomenon of phantom limb pain has been well documented for centuries, but little clinical work has been done to alleviate it. Physician and neuroscientist Vilayanur S. Ramachandran began researching this condition nearly two decades ago, and has discovered a promising alternative treatment: mirror-box therapy. This therapy is not yet...
Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and
duration of vegetation control on wood quality near the pith...
