Numbering-Up of Microscale Devices for Megawatt-Scale Supercritical Carbon Dioxide Concentrating Solar Power Receivers

Creator:: Zada, Kyle R., Hyder, Matthew B., Drost, M. Kevin, and Fronk, Brian M.
Abstract:: Concentrated solar power (CSP) plants have the potential to reduce the consumption of nonrenewable resources and greenhouse gas emissions in electricity production. In CSP systems, a field of heliostats focuses solar radiation on a central receiver, and energy is then transferred to a thermal power plant at high temperature. However,...

Evaluation of Heat and Mass Transfer Models for Sizing Low-Temperature Kalina Cycle Microchannel Condensers

Creator:: Fronk, Brian M. and Zada, Kyle R.
Abstract:: Waste heat driven ammonia/water Kalina cycles have shown promise for improving the efficiency of electricity production from low-temperature reservoirs (T < 150 °C). However, there has been limited application of these systems to utilize widely available, disperse, waste heat streams for smaller scale power production (1–10 kWe). Factors limiting increased deployment of these...

High-Flux Thermal Management With Supercritical Fluids

Creator:: Fronk, Brian M. and Rattner, Alexander S.
Abstract:: A novel thermal management approach is explored, which uses supercritical carbon dioxide (sCO2) as a working fluid to manage extreme heat fluxes in electronics cooling applications. In the pseudocritical region, sCO2 has extremely high volumetric thermal capacity, which can enable operation with low pumping requirements, and without the potential for...

Limitations of Species Delimitation Based on Phylogenetic Analyses: A Case Study in the Hypogymnia hypotrypa Group (Parmeliaceae, Ascomycota)

Creator:: Wei, Xinli, McCune, Bruce, Lumbsch, H. Thorsten, Li, Hui, Leavitt, Steven, Yamamoto, Yoshikazu, Tchabanenko, Svetlana, and Wei, Jiangchun
Abstract:: Delimiting species boundaries among closely related lineages often requires a range of independent data sets and analytical approaches. Similar to other organismal groups, robust species circumscriptions in fungi are increasingly investigated within an empirical framework. Here we attempt to delimit species boundaries in a closely related Glade of lichen-forming fungi...

Evaluating carbon storage, timber harvest, and habitat possibilities for a Western Cascades (USA) forest landscape

Creator:: Kline, Jeffrey D., Harmon, Mark E., Spies, Thomas A., Morzillo, Anita T., Pabst, Robert J., McComb, Brenda C., Schnekenburger, Frank, Olsen, Keith A., Csuti, Blair, and Vogeler, Jody C.
Abstract:: Forest policymakers and managers have long sought ways to evaluate the capability of forest landscapes to jointly produce timber, habitat, and other ecosystem services in response to forest management. Currently, carbon is of particular interest as policies for increasing carbon storage on federal lands are being proposed. However, a challenge...

Complexity Increases Predictability in Allometrically Constrained Food Webs

Creator:: Iles, Alison C. and Novak, Mark
Abstract:: All ecosystems are subjected to chronic disturbances, such as harvest, pollution, and climate change. The capacity to forecast how species respond to such press perturbations is limited by our imprecise knowledge of pairwise species interaction strengths and the many direct and indirect pathways along which perturbations can propagate between species....

Creator:: Salas, Jacqueline
Abstract:: A poster explaining how the transtheoretical model can be applied to a case management intervention to help reduce BMI among a specific population. Specifically, this piece depicts the application of it to obese African American children by examining their eating habits and increasing their physical activity.

Non-forest Plant Communities of the Northern Oregon Coast Range and Vicinity Draft Report

Creator:: Glavich, Doug
Abstract:: DRAFT REPORT. In 2013 – 2015, reconnaissance observations were made across non-forest habitats on FS and BLM land in the Coast Range and Cascade foothills within the Salem and Eugene BLM district areas for plant communities that did not fit the USFS Northwest Oregon Non-forest Plant Community guide. Surveys were...

Article Deposit Services in Support of Federal Agency Public Access Requirements

Creator:: Boock, Michael, Zhang, Hui, and Clark, Erin
Abstract:: INTRODUCTION: Academic libraries have experimented with a variety of services to encourage article deposit to institutional repositories, with varying degrees of success. Universities now face the challenge of meeting federal agency public access requirements. Following the White House Office of Science Technology and Policy public access directive in 2013, Oregon...

Toward a digital resilience

Creator:: Wright, Dawn J.
Abstract:: As we contend with human impacts on the biosphere, there is rightfully a great emphasis now on community adaptation and resilience to climate change. Recent innovations in information technologies and analyses are helping communities to become more resilient. However, not often discussed in this vein is a path toward digital...

Perchlorate Exposure Reduces Primordial Germ Cell Number in Female Threespine Stickleback

Creator:: Petersen, Ann M., Earp, Nathanial C., Redmond, Mandy E., Postlethwait, John H., von Hippel, Frank A., Buck, C. Loren, and Cresko, William A.
Abstract:: Perchlorate is a common aquatic contaminant that has long been known to affect thyroid function in vertebrates, including humans. More recently perchlorate has been shown to affect primordial sexual differentiation in the aquatic model fishes zebrafish and threespine stickleback, but the mechanism has been unclear. Stickleback exposed to perchlorate from...

Trait-mediated indirect interactions among residents of rocky shore tidepools

Creator:: Morgan, Steven G., Gravem, Sarah A., Lipus, Adam C., Grabiel, Marcos, and Miner, Benjamin G.
Abstract:: Trait-mediated indirect interactions (TMIIs) are an important component of food web structure and dynamics. We determined whether TMIIs occur in rocky tidepool communities on the west coast of the USA. In the laboratory, both adults and juveniles of the keystone predator Pisaster ochraceus and adults of a smaller predatory seastar...

The Power of Three: Coral Reefs, Seagrasses and Mangroves Protect Coastal Regions and Increase Their Resilience

Creator:: Guannel, Greg, Arkema, Katie, Ruggiero, Peter, and Verutes, Gregory
Abstract:: Natural habitats have the ability to protect coastal communities against the impacts of waves and storms, yet it is unclear how different habitats complement each other to reduce those impacts. Here, we investigate the individual and combined coastal protection services supplied by live corals on reefs, seagrass meadows, and mangrove...

The Impact of Intramammary Escherichia coli Challenge on Liver and Mammary Transcriptome and Cross-Talk in Dairy Cows during Early Lactation Using RNAseq

Creator:: Moyes, K. M., Sørensen, P., and Bionaz, M.
Abstract:: Our objective was to identify the biological response and the cross-talk between liver and mammary tissue after intramammary infection (IMI) with Escherichia coli (E. coli) using RNAseq technology. Sixteen cows were inoculated with live E. coli into one mammary quarter at ~4–6 weeks in lactation. For all cows, biopsies were...

The Role of Seagrass Traits in Mediating Zostera noltei Vulnerability to Mesograzers

Creator:: Martínez-Crego, Begoña, Arteaga, Pedro, Tomas, Fiona, and Santos, Rui
Abstract:: Understanding how intra-specific differences in plant traits mediate vulnerability to herbivores of relevant habitat-forming plants is vital to attain a better knowledge on the drivers of the structure and functioning of ecosystems. Such studies, however, are rare in seagrass-mesograzer systems despite the increasingly recognized relevance of mesograzers as seagrass consumers....

Creator:: Kirkwood, Jay S., Miranda, Cristobal L., Bobe, Gerd, Maier, Claudia S., and Stevens, Jan F.
Abstract:: The differentiation of precursor cells into mature adipocytes (adipogenesis) has been an area of increased focus, spurred by a rise in obesity rates. Though our understanding of adipogenesis and its regulation at the cellular level is growing, many questions remain, especially regarding the regulation of the metabolome. The 3T3-L1 cell...

Three-Dimensional Reflectance Traction Microscopy

Creator:: Kim, Jihan, Jones, Christopher A. R., Groves, Nicholas Scott, and Sun, Bo
Abstract:: Cells in three-dimensional (3D) environments exhibit very different biochemical and biophysical phenotypes compared to the behavior of cells in two-dimensional (2D) environments. As an important biomechanical measurement, 2D traction force microscopy can not be directly extended into 3D cases. In order to quantitatively characterize the contraction field, we have developed...
