Wood plastic composites (WPCs) are composite materials made from thermoplastic polymers, wood flour, and a small amount of process- and property-enhancing additives; they are principally used in the automotive industry and as secondary building materials. Although the WPC market is expected to keep growing, it is still relatively small when...
In the context of forest products, a cutting order is a list of dimension parts along with demanded quantities. The cutting-order problem is to minimize the total cost of filling the cutting order from a given lumber grade (or grades). Lumber of a given grade is supplied to the production...
Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...
Natural products from both terrestrial and marine sources represent a significant source of novel drug leads, and have previously been developed into clinically-approved agents for the treatment of various human diseases. This work represents the biological characterization of the mechanistic basis for activity of several natural product structures in models...
The purpose of this study was to determine the accuracy of placing
adults in reading materials based on scores from a word-opposite test.
The population was randomly selected from students attending
developmental education classes at three Oregon community colleges.
The Word Opposite Reading Placement Instrument (WOPI) was derived
from a...
Background: Spina bifida (SB) is the most common birth defect, affecting approximately 1 to 2 in 10,000 live births. SB is a complex disability with many associated, secondary, and chronic conditions that require lifelong medical care. Individuals with spina bifida (SB) are living longer with advances in medical care, and...
Experiments were performed to determine the nature of
maize influence on bean disease in additive-type
intercrops. Overall effects of intercrops on angular leaf
spot (caused by Phaeoisariopsis griseola) in Kenya
indicated >23% reductions (P<0.05) in area under the
disease progress curve (AUDPC) in two of three season-site
combinations. Fertilization tended...
