Buoyancy regulation by hatchery and wild coho salmon during the transition from freshwater to marine environments

Creator:: Weitkamp, Laurie A.
Abstract:: One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter their whole-fish density (WFD) or they will become positively (float) or negatively (sink) buoyant as they change environments....

Reproductive biology and behavior of the brown tree snake (Boiga irregularis) on Guam.

Creator:: Waye, Heather L.
Abstract:: While there are many more species of reptiles in the tropics than in temperate latitudes, relatively little is known about the natural history of tropical species of snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate...

Dixy Lee Ray, marine biology, and the public understanding of science in the United States (1930-1970)

Creator:: Ellis, Erik
Abstract:: This dissertation focuses on the life of Dixy Lee Ray as it examines important developments in marine biology and biological oceanography during the mid twentieth century. In addition, Ray's key involvement in the public understanding of science movement of the 1950s and 1960s provides a larger social and cultural context...

The role of competition, community, and priority in the discovery of the tau lepton

Creator:: Swanner, Leandra
Abstract:: This study examines the interactions between the scientific communities of the Lawrence Berkeley Laboratory (LBL) and the Stanford Linear Accelerator Center (SLAC) in the discovery of the tau lepton by physicist Martin Perl between 1973- 1977. Perl became interested in searching for heavy leptons through positron-electron collision experiments using the...

Alteration of cholesterol disposition by chlordecone is not explained by induction of cyp7a or cyp4a1

Creator:: Lee, JungA
Abstract:: Liver X receptor (LXR), farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) are adopted orphan nuclear receptors that function as lipid sensors. These receptors respond to cellular lipid levels and regulate the expression of target gene. Previously, it was demonstrated that low doses of chlordecone (CD) pretreatment disturbed exogenous...

Modeling the Oregon State University TRIGA Reactor Using the Attila Three-Dimensional Deterministic Transport Code

Creator:: Keller, S. Todd
Abstract:: Attila is a state-of-the-art radiation transport based code that is efficient, accurate and straightforward to use. Geometric information is input to the code as CAD drawings. Material property information is input as a cross section library. The user has full control over standard transport options and output reports. In phase...

Understanding the principles and procedures to retain green and red pigments in thermally processed peels-on pears (Pyrus communis L.)

Creator:: Ngo, Thao Xuan
Abstract:: Thermal stabilization of chlorophyll and anthocyanin on pear peels during thermal process was investigated in this study. The green color of peels-on thermally processed (canned) pears was successfully retained by complexation of magnesium-free chlorophyll with zinc ions, and the red pigments were stabilized through anthocyanin-stannous complexation and polymerization of pear...

Interactions of auxin with ethylene and gravity in regulating growth and development in tomato (Lycopersicon esculentum, Mill.)

Creator:: Madlung, Andreas
Abstract:: Plant growth, development, and environmental responsiveness are dependent on hormone-induced gene expression. This dissertation reports multiple interactions between the plant hormones auxin and ethylene and investigates their contribution to the gravitropic response, elongation growth, adventitious root formation, callus and tracheary element initiation and growth, and flower development. Four mutants of...

A study of adult student learning strategies for a web based teacher licensure program

Creator:: Twomey, Sylvia Mary
Abstract:: The purpose of this study was to understand how adult learners in an online teacher licensure program selected and used learning strategies, transformed existing strategies or developed new strategies. Also examined was whether the environment itself facilitated or impeded usage of transformed strategies, or development of new strategies. Participants in...
