In silico clinical trial comparing predicted subsequent malignant neoplasms in photon versus proton therapy of a pediatric cohort with intracranial tumors

Creator:: Gallagher, Kyle J.
Abstract:: The leading cause of death 20 years after treatment for children surviving a cancer of the central nervous system was from a subsequent malignant neoplasm (SMN) (1). Although it was been shown that proton therapy considerably reduces the risk of a fatal SMN in children receiving craniospinal irradiation compared to...

Beaver ecology in Bridge Creek, a tributary to the John Day River

Creator:: Maenhout, Julie L. (Harper)
Abstract:: The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...

Properties of low-level marine clouds as deduced from advanced very high resolution radiometer satellite observations

Creator:: Chang, Fu-Lung
Abstract:: A radiation model was developed for retrieving cloud visible optical depth, droplet effective radius, and cloud top emission temperature using AVHRR satellite observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity of the retrieved properties to various approximations often employed in such retrievals. Droplet...

The effects of native plants on non-native plant abundance in a restoration setting : differences among native species and the predictive ability of species traits

Creator:: Goodridge, Jennifer M.
Abstract:: Reducing the cover of non-native species is one of the challenges of ecosystem restoration. The goal of this study is to identify native species traits that will increase native species cover and reduce non-native species cover in the first growing season at upland and wetland prairie restoration sites. Native and...

The weather pattern and trends associated with Gulf Stream turbulent heat loss events

Creator:: Loyd, Nicholas
Abstract:: The weather pattern and trends associated with heat flux events (HFEs) over the Gulf Stream (GS) are examined as part of the CLIMODE project. A large portion of GS turbulent heat loss occurs during distinct synoptic scale events with a duration of one to two days. Forty percent (40%) of...

Toxicity of methyl bromide to fungi inhabiting Dahurian larch wood

Creator:: Rhatigan, Ronald G.
Abstract:: Concerns over the possibility of exotic pest introductions from eastern Russia to the West Coast of the United States due to proposed log imports raises the question of the effectiveness of possible mitigation measures. Toxicity of methyl bromide to representative pathogenic fungi was tested by exposing Armillaria ostoyae, Heterobasidion annosum,...

Effects of solar heating on the indirect effect of aerosols as deduced from observations of ship tracks

Creator:: Christensen, Matthew W.
Abstract:: One kilometer Moderate Resolution Imaging Spectroradiometer (MODIS) observations for Terra (morning) and Aqua (afternoon) satellites were used to follow the morning to afternoon evolution of marine stratocumulus clouds that were affected by ship stack exhaust. The observations covered the summer months of 2002-2003 and August 2007 for marine layers off...

Nitrogen dynamics across silvicultural canopy gaps in young forests of western Oregon

Creator:: Thiel, Aaron L.
Abstract:: Silvicultural canopy gaps are emerging as an alternative management tool to accelerate development of complex forest structure in young, even-aged forests of the Pacific Northwest. I investigated patterns of nitrogen (N) availability along transects through 0.1 and 0.4 ha silvicultural gaps in three 50-70 year old Douglas-fir forests of western...

Development of a synoptic map-pattern climatology to supplement current weather forecasting methods

Creator:: Frey, Melissa D. (Melissa Dawn)
Abstract:: Many meteorologists rely heavily on their experience of past weather events to supplement their forecasting tools, such as using past experience to help decide between conflicting numerical weather prediction models. Experiential knowledge is an important piece of forecasting, however it is highly subjective and variable from one forecaster to another....
