The objective of this research was to clarify the basis
of subfertility in Delaware roosters. It was anticipated
that a sensitive method would be needed to compare seminal
plasma protein composition between subfertile and fertile
roosters. Consequently, the applicability of two-dimensional
electrophoresis was tested as a tool for the
analysis...
Dekalb XL Single Comb White Leghorn pullets were
immunized against poly-L-glutamic acid (PGA) complexed with
methylated bovine serum albumin (MBSA) at 9 weeks of age.
Pullets immunized against MBSA as well as non-immunized
pullets served as controls. At 18 weeks of age, pullets
were moved from a floor pen into...
Twelve rock units, from upper Eocene to middle Miocene are exposed in the Nicolai Mountain-Gnat Creek area. They are, from oldest to youngest: Pittsburg Bluff Formation; Oswald West mudstone; Big Creek sandstone, upper Silver Point mudstone, and
Pipeline mudstone members of the Astoria Formation; Depoe Bay Basalt; Grande Ronde Basalt;...
Anaerobic digestion of lipid-extracted algal biomass has been proposed as a method to
recover and recycle nutrients in algal biofuel systems. The purpose of this study was to quantify recoverable nitrogen and phosphorus from anaerobically digested C. vulgaris. Recoverable nutrients were deemed those present in the liquid phase of anaerobic...

Large scale production requires substantial inputs of nutrients
Agonistic behavior among three species of Microtus live-trapped
near Corvallis, Oregon was recorded in order to interpret habitat
segregation by the species in areas of syrnpatry. The method used to
measure agonistic interaction was similar to that of Colvin (1970).
Agonistic behavior was recorded under red light in a neutral...
Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic
studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment
depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...
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...
