A Simple Leapfrog Integration Scheme to Find Optimal Interplanetary Trajectories

Creator:: Kelley, Scott M.
Abstract:: The calculation of interplanetary trajectories is a numeric problem which requires a high degree of precision for the results to be accurate. A computer program was written for this project which uses leapfrog integration combined with Newton’s method of iterative root finding to find ideal interplanetary trajectories. Reasonable initial conditions...

Melting Stage Analysis for Indirect Freeze Desalination

Creator:: Pratt, Mason G.
Abstract:: To investigate the melting stage of indirect freeze desalination three numerical models were developed. A zeroth, ﬁrst, and second order analyses modeled the melting of ice around the outside of a pipe as a function of time. The zeroth order analysis assumes the system to be steady state. The ﬁrst...

Reliability Analysis of a Freeze Desalination System

Creator:: Boschetti Tofano, Francisco A.
Abstract:: The unsustainable use of fresh water sources and unavailability of fresh water in certain parts of the world have created a demand for water desalination systems. Desalination methods are effective at producing consumable water, but often require large scale setups, high energy consumption, and careful maintenance. A team of students...

Coaching teachers to implement innovations in STEM

Creator:: Giamellaro, Michael and Siegel, Deborah R.
Abstract:: STEM is evolving as a discipline and includes challenging educational practices. Teachers need support to address these challenges and implement STEM. We present an intervention in which a STEM coach supported teachers implementing STEM across a school district. The coach role was valued for (1) connecting to outside resources, (2)...

The Willamette Valley (Oregon) Prairie Plant Trait Dataset

Creator:: Clark, Deborah and Wilson, Mark V.
Abstract:: The Willamette Valley (Oregon) Prairie Plant Trait Dataset is a compilation of plant traits of species important in upland prairies, wetland prairies, vernal pools, and emergent wetlands, and in the restoration of prairies and wetlands of the Willamette Valley of Oregon. These species are also found widely throughout the Pacific...

Hydroacoustic monitoring of oceanic spreading centers: Past, present, and future

Creator:: Dziak, Robert P., Bohnenstiehl, Delwayne R., and Smith, Deborah K.
Abstract:: Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means available to observe seafloor-spreading events in real time is via the remote detection of the seismicity...

A Dysfunctional System: Policy Recommendations for the Adult (18-65) Homeless and Severely Mentally Ill Population in Oregon

Creator:: Miller, Donielle F.
Abstract:: Adults with severe and persistent mental illness (SPMI) are overrepresented in the homeless population, and Oregon’s homeless population has expanded in recent years. In the 1950s, the mentally ill were moved out of the state hospitals and into the community. However, due to a lack of support services in the...

"You're Really Gonna Kick Us All Out?" Sustaining Safe Spaces for Community-Based HIV Prevention and Control among Black Men Who Have Sex with Men

Creator:: Garcia, Jonathan, Parker, Caroline, Parker, Richard G., Wilson, Patrick A., Philbin, Morgan M., and Hirsch, Jennifer S.
Abstract:: Black men who have sex with men (BMSM) experience among the highest rates of HIV infection in the United States. We conducted a community-based ethnography in New York City to identify the structural and environmental factors that influence BMSMs vulnerability to HIV and their engagement with HIV prevention services. Methods...

Assessment of fecal steroid and thyroid hormone metabolites in eastern North Pacific gray whales

Creator:: Lemos, Leila S., Olsen, Amy, Smith, Angela, Chandler, Todd E., Larson, Shawn, Hunt, Kathleen, and Torres, Leigh G.
Abstract:: Baleen whale fecal samples have high potential for endocrine monitoring, which can be used as a non-invasive tool to identify the physiological response to disturbance events and describe population health and vital rates. In this study, we used commercial enzyme-linked immunosorbent assays to validate and quantify fecal steroid (progestins, androgens...

Volcanic Eruptions in the Deep Sea

Creator:: Rubin, Kenneth H., Soule, S. Adam, Chadwick, William W., Jr., Fornari, Daniel J., Clague, David A., Embley, Robert W., Baker, Edward T., Perfit, Michael R., Caress, David W., and Dziak, Robert P.
Abstract:: Volcanic eruptions are important events in Earth’s cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary ejecta, transfer heat and magmatic volatiles from Earth’s interior to the overlying air or seawater, and significantly modify the landscape and perturb...
