Graphical coding data and operational guidance for implementation or modification of a LabVIEW®-based pHstat system for the cultivation of microalgae

Creator:: Golda, Rachel L., Needoba, Joseph A., Golda, Mark D., and Peterson, Tawnya D.
Abstract:: The influence of pH on phytoplankton physiology is an important facet of the body of research on ocean acidification. We provide data developed during the design and implementation of a novel pHstat system capable of maintaining both static and dynamic pH environments in a laboratory setting. These data both help...

Development of an economical, autonomous pHstat system for culturing phytoplankton under steady state or dynamic conditions

Creator:: Golda, Rachel L., Golda, Mark D., Hayes, Jacqueline A., Peterson, Tawnya D., and Needoba, Joseph A.
Abstract:: Laboratory investigations of physiological processes in phytoplankton require precise control of experimental conditions. Chemostats customized to control and maintain stable pH levels (pHstats) are ideally suited for investigations of the effects of pH on phytoplankton physiology, for example in context of ocean acidification. Here we designed and constructed a simple,...

Determination of intracellular pH in phytoplankton using the fluorescent probe, SNARF, with detection by fluorescence spectroscopy

Creator:: Golda-VanEeckhoutte, Rachel L., Roof, Lauren T., Needoba, Joseph A., and Peterson, Tawnya D.
Abstract:: The maintenance of pH homeostasis is critical for a variety of cellular metabolic processes. Although ocean acidification is likely to influence cellular metabolism and energy balance, the degree to which intracellular pH in phytoplankton differs from the external environment under varying environmental pH levels is not well characterized. While there...

Assessing the Influence of Environmental pH on Algal Physiology Using a Novel Culture System

Creator:: Golda, Rachel
Abstract:: Since the Industrial Revolution, surface ocean pH has declined due to the input of anthropogenically derived carbon dioxide, termed ocean acidification. Examinations of phytoplankton physiology in the face of changing pH are becoming more important as anthropogenically-driven pH decreases in the surface ocean progress (termed ocean acidification). Previous research has...

Public Perception of Natural Gas Export: The Jordan Cove Energy Project

Creator:: Mooney, Rachel L.
Abstract:: Fracking and natural gas have been widely studied in public opinion research over the years, but few studies evaluate natural gas export and the perceptions of its associated economic benefits and environmental risks. Since the shale revolution in the early 2000s, the U.S. transitioned from a net natural gas importer...

Exploring the relationship between engineering design project characteristics and risk indicators

Creator:: Yim, Rachel L.
Abstract:: Engineering design projects are implemented to accomplish a variety of goals in organizations. As the complexity of each project grows, the risk and uncertainty accompanying each project increases as well. As a result project managers must identify potential risks to projects and create plans to avoid realized risks leading to...

Highway finance and the impacts on road quality

Creator:: Knutson, Rachel L.
Abstract:: In recent years there has been concern over the deterioration and lack of adequate funding for the US road and highway system. The main goals of this study are to examine how increasing use of general financing methods effects road quality, to determine if capital outlay and maintenance expenditure impact...

Classification of Native Vegetation of Oregon - 2019

Creator:: Kagan, James S., Brunner, Rachel L., and Christy, John A.
Abstract:: This classification is an update of the 2004 classification of native vegetation of Oregon by Kagan, Christy, Murray and Titus. As before, this classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were part of the presettlement landscape of...

Creator:: Palmer, Rachel M., Billman, E. J., Danley, C., Sharpe, C., and Noakes, D. L. G.
Abstract:: As juvenile salmon migrate from freshwater into saltwater, physiological changes must occur to allow fish to osmoregulate in the marine environment. Juvenile spring Chinook salmon migrate to the ocean at different time periods, most notably in the fall (August – November; i.e. fall smolts) and spring (February – May; i.e....
