Four charges of S-inch paper roll plugs of Oregon maple were kiln-dried at various temperatures and humidities. The charge with the most desirable combination of short drying time and low degrade was dried to 12 per cent moisture content in lit hours, using a dry-bulb temperature of 160 degrees F...
The Willamette River flows north between the Cascade Mountains and Coast Range of western Oregon within a 29,728-km² basin. The fish community in the geologically young basin consists of 36 native species, but introductions of non-native fishes have added 33 additional species for a total of 69 fish species. During...
Graphical methods for displaying uncertainty are often the most concise and informative way to communicate abstract concepts. Presentation methods currently in use for the display and interpretation of scientific uncertainty are reviewed. Numerous subjective and objective uncertainty display methods are presented, including qualitative assessments, node and arrow diagrams, standard statistical...
The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)]
tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions.
The absorption spectra of the
chelates formed were measured with a recording spectrophotometer
between 200 and 700 mμ. The pH of each solution was varied and a
spectrum was scanned...
OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...
A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...
In summary, as detailed below in Section III, we recommend the 2007 Legislature put
Measure 37 back on the track of fair and honest compensation for all claimants, and corral the
threat to Willamette Valley agriculture at the same time, by providing as follows:
• Whether in the form of...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
