This presentation and the 1986 visit to Oregon were by invitation from Oregon State University and the Wine Advisory Board, and supported by the Sokol Foundation. The ideal cooperation of Professor Porter Lombard and Mr. Steve Price is most gratefully acknowledged. We were in a learning experience, and humble in...
The synthesis of superheavy element evaporation residues is described by the product of the capture cross section, fusion probability, and survival probability. Capture cross sections are moderately well known. The fusion probability is the least known with many uncertainties. The formalism for the survival probability is known, but the parameters...
Grape powdery mildew (GPM, causal agent Erysiphe necator) is the most economically important disease of grapevine in the Western U.S. Low levels of GPM infection on clusters (1-5%) can negatively affect wine sensory quality, so intensive fungicide programs are common. This may lead to problems like excessive fungicide use and...
Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...
A tracer method utilizing stable activable tracers (involving rare earth nuclides with short-lived t[subscript 1/2] < 1 day} activation products) for tracing fluid bound substances in fresh water is explored. Simulated laboratory studies showed these tracers (Dy and in) when chelated with diethylenetriamine2entaacetic acid a7i1W to be stable ( <20%)...
The atmospheric trace element abundances associated with
several major sources of air pollution in Western Oregon, such as the
paper industry, the metallurgical processing industry, the plywood
industry and agricultural field burning have been measured by instrumental
neutron activation analysis (INAA). Air samples were collected
directly from industrial stacks and...
The purpose of the present study was to determine the association
of initial weight, average daily gain, days on feed, percent total
digestible nutrients (TDN) and percent digestible protein in the ration
with USDA carcass grade, marbling score, conformation score, back
fat thickness and area of longissimus dorsi of beef...
Podosphaera macularis causes one of the most important diseases, powdery mildew, of Humulus lupulus (hop). If left unmanaged, hop powdery mildew can cause total crop loss due to disease or browning of hop cones rendering the cones unmarketable to buyers. The Hop Powdery Mildew Infection Risk Index (HOPS) is heavily...
