Abstract:: We examined variability in the natural fluorescence yield of a neritic diatom, Thalassiosira weissflogii, in continuous cultures. In this species, kinetics in natural fluorescence yield over time scales less than a photoperiod were characterized by sharp decreases, occurring at irradiance intensities that presumably coincide with the onset of nonphotochemical fluorescence...

Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...

Creator:: Johnson, Samuel T., Golden, Grace M., Mercer, John A., Mangus, Brent C., and Hoffman, Mark A.
Abstract:: Form skipping has been used to help injured athletes progress to running. Because little research has been done on form-skipping mechanics, its justifi cation as a progression to running exercises is unclear. Objective: To compare groundreaction forces (GRF) during form skipping and running in healthy subjects at clinically relevant speeds,...

Creator:: Desiderio, Russell A., Laney, Samuel R., Letelier, Ricardo M., and Giovannoni, Stephen J.
Abstract:: We constructed an experimental apparatus that used lasers to provide the probe beams for measuring the transient absorption kinetics of bacterioplankton that contain proteorhodopsin, a microbial protein that binds retinal and is analogous to animal rhodopsin. With this approach we were able to observe photocycles characteristic of functioning retinylidene ion...

Abstract:: Oregon is a gardener’s dream. Our varied climates and mild conditions allow us to showcase a wide variety of plants from around the world. In fact, nursery crops are Oregon’s number one agricultural commodity. Unfortunately, a few plants used in gardens and landscapes cause serious ecological harm by ‘jumping the...
