Swiss needle cast (SNC) is a disease specific to Douglas-fir (Pseudotsuga menziesii) caused by the ascomycete Phaeocryptopus gaeumannii. Here we examine characteristics of the EM fungus community that are potentially useful in predictive models that would monitor forest health. We found that mean EM density (number of colonized root tips/soil...
The amine extraction process is evaluated for pulse column
operation. A 0.1 M solution of Primene JM-T (a commercial mixture
of tertiary-alkyl primary amines) in a kerosene-base diluent is
the extractant for thorium feed in aqueous acidic sulfate solutions.
Equilibrium isotherms at room temperature are presented at
aqueous acidities of...
Electrical stimulation of beef carcasses (n=18) did not cause a
significant reduction in microbial population on three different sampling
positions immediately following slaughter. In constrast, significant
microbial reduction (P > 0.05) was found at position 2 (muscle
above aitch bone), but not at position 1 (inside of neck) or position...
The mycorrhizal rootlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) and red alder (Alnus rubra Bong.) were extensively investigated. A jet-black mycorrhiza was found to be dominant on Douglas-fir rootlets. The fungal symbiont was identified as Cenococcum graniforme (Sow.) Ferd. and Winge. Two forms of mycorrhizae predominated on root systems of...
This thesis presents a study of applications and techniques for molecular dynamics simulations. Three studies are presented that are intended to improve our ability to simulate larger systems more realistically. A comparison study of two- and three-body potential models for liquid and amorphous Si0₂ is presented. The structural, vibrational, and...
