This work set out to examine the methodologies of dry hopping, compare different hop materials, and look at the extraction behavior of different types of hop compounds. This work consists of two discrete studies, where the first study informed the design of the second.
The first study measured the concentrations...
Hypermediation, as described by Jay Bolter and Richard Grusin in their book Remediation, is a style of writing, recording, presenting, etc. that “makes us aware of the medium or media and (in sometimes subtle and sometimes obvious ways) reminds us of our desire for immediacy” (34). This mode of production...
A series of four trials was conducted to evaluate activated
sewage sludge (AcSS) as a protein source. In the first trial the protein
efficiency ratio (PER) of sun-dried and auto-claved, sun-dried
AcSS was measured with rats. Growth of AcSS-fed rats was extremely
poor as compared to those rats fed casein,...
Objectives: Nitrate, found abundantly in green leafy vegetables, may improve exercise performance by increasing the availability and utilization of metabolic fuels that require less oxygen for energy production. However, it is not known if this performance effect occurs at the peak exercise intensity. We hypothesize that supplemental nitrate treatment will...
This research examines the impact of low health literacy among patients with End Stage Renal Disease. The sample included individuals who participated in a health education class (Pre-Renal Education Program) offered at the Samaritan Dialysis Services in Corvallis, Oregon. Data collection techniques included participant observation, individual interviews, evaluation of the...
A major objective of this investigation was to determine the
possible roles, if any, of poly-β-hydroxybutyrate and products of
its metabolic breakdown in symbiotic nitrogen fixation by nodule
bacteroids. Changes in poly -β- hydroxybutyrate content and in
activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and
isocitrate lyase were studied under various conditions...
Based upon the Pearson Type VIII distribution function,
a general retention function which relates the saturation to
the capillary pressure in disturbed soils has been discovered.
This simple and yet complete function has been
shown to describe precisely the imbibition as well as the
drainage branch of the retention curve....
PART I. The concentration of nickel in some soils may be
insufficient to meet the requirements of enzymes such as
urease in soybeans and hydrogenase in Rhizobium. Nickel
availability in soils was examined by measuring microbial
urease activity in soils which were treated with glucose
and urea. Supplemental nickel was...
Experiments are reported which demonstrate that a cobalt deficiency
in R. meliloti results in a decreased cytochrome content of
bacterial cells. It is concluded that the effect of cobalt deficiency
on cytochrome content of Rhizobium cells and on the leghemoglobin
content of nodules possibly may be explained by an effect...
Alnus rubra (Bong. ) seedlings were grown in sand culture and
irrigated with nutrient solution containing CdCl₂
ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks
with 50 and 100 mg CdCl₂
per liter of nitrogen-free nutrient solution
decreased in situ nitrogenase...
