Effect of metformin exposure on growth and photosynthetic performance in the unicellular freshwater chlorophyte, Chlorella vulgaris

Creator:: Cummings, Brittany M., Needoba, Joseph A., and Peterson, Tawyna D.
Abstract:: Many pharmaceuticals have negative effects on biota when released into the environment. For example, recent work has shown that the commonly prescribed antidiabetic drug, metformin (N,N-dimethylbiguanide), has endocrine disrupting effects on fish. However, effects of metformin on aquatic primary producers are poorly known. We exposed cultured isolates of a freshwater...

Comparison of energy systems in Small Island Developing States

Creator:: Surroop, Dinesh, Raghoo, Pravesh, and Bundhoo, Zumar M. A.
Abstract:: Small Island Developing States (SIDS) have been amongst the most neglected group with regard to energy access until recently when several voices were raised to highlight the vulnerabilities of these small nations. Since then, their levels of energy access have become the focus of significant attention. These levels vary over...

Internal photoemission spectroscopy determination of barrier heights between Ta-based amorphous metals and atomic layer deposited insulators

Creator:: Jenkins, M. A., McGlone, J. M., Wager, J. F., and Conley, J. F., Jr.
Abstract:: The energy barrier heights between two recently reported Ta-based amorphous metals (TaWSi and TaNiSi), TaN, and atomic layer deposited Al2O3 and HfO2 insulators are measured in metal/insulator/metal (MIM) structures with Au top electrodes using internal photoemission (IPE) spectroscopy. For Al2O3, the Ta-based metal barrier heights, phi(Bn), increase with increasing metal...

Greater sage-grouse vital rates after wildfire

Creator:: Foster, Lee J., Dugger, Katie M., Hagen, Christian A., and Budeau, David A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) have been subject to long-term and continuing declines in population and habitat since European settlement of western North America. Increased wildfire activity constitutes a primary threat to the species in western portions of their range, with documented declines in wildfire-affected populations. Following a 187,000-ha wildfire in...

Variations in Gas and Water Pulses at an Arctic Seep: Fluid Sources and Methane Transport

Creator:: Hong, Wei-Li, Torres, Marta E., Portnov, A., Waage, M., Haley, B., and Lepland, A.
Abstract:: Methane fluxes into the oceans are largely dependent on the methane phase as it migrates upward through the sediments. Here we document decoupled methane transport by gaseous and aqueous phases in Storfjordrenna (offshore Svalbard) and propose a three-stage evolution model for active seepage in the region where gas hydrates are...

Community Water Improvement, Household Water Insecurity, and Women's Psychological Distress: An Intervention and Control Study in Ethiopia

Creator:: Stevenson, E. G. J., Ambelu, A., Caruso, B. A., Tesfaye, Y., and Freeman, M. C.
Abstract:: Background: Over 650 million people worldwide lack access to safe water supplies, and even among those who have gained access to ‘improved’ sources, water may be seasonally unreliable, far from homes, expensive, and provide insufficient quantity. Measurement of water access at the level of communities and households remains crude, and...

Spec Kit 360: Learning Analytics

Creator:: Perry, Michael R. , Briney, Kristin A., Goben, Abigail, Asher, Andrew, Jones, Kyle M. L. , Robertshaw, M. Brooke, and Salo, Dorothea
Abstract:: This SPEC Kit examines current practices, policies, and ethical issues around libraries and learning analytics. It explore how ARL member institutions are navigating the balance between gathering and managing data in support of learning analytics initiatives and attending to the profession’s ethics commitments. To these ends, it seeks to answer...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...

Remodeling of skeletal muscle mitochondrial proteome with high-fat diet involves greater changes to beta-oxidation than electron transfer proteins in mice

Creator:: Dasari, Surendra, Newsom, Sean A., Ehrlicher, Sarah E., Stierwalt, Harrison D., and Robinson, Matthew M.
Abstract:: Excess fat intake can increase lipid oxidation and expression of mitochondrial proteins, indicating remodeling of the mitochondrial proteome. Yet intermediates of lipid oxidation also accumulate, indicating a relative insufficiency to completely oxidize lipids. We investigated remodeling of the mitochondrial proteome to determine mechanisms of changes in lipid oxidation following high-fat...

Benthic Habitat Mapping: eCognition Rule Set

Creator:: O’Neil-Dunne, Jarlath P. M., Parrish, Christopher E., and Dijkstra, Jennifer A.
Abstract:: This publication consists of a rule set for benthic habitat classification implemented in eCognition (Trimble Navigation Limited). The details of the procedure are described in Parrish et al., 2016: http://www.jcronline.org/doi/abs/10.2112/SI76-017. The input to the classification consists of high-resolution true color orthophotos, seafloor DEMs from topobathymetric lidar, and gridded lidar reflectance...
