The shallow, poorly-confined, sand and gravel aquifer underlying the lower
Malheur River basin is contaminated by nitrate and metabolites of the herbicide
dimethyl tetrachloroterephthalate (DCPA), first detected in 1983 and 1985,
respectively. The aquifer supplies water for the Ontario municipal water system,
domestic and industrial uses, and irrigation. In response...
The major purpose of this study was to determine if there were differences between well-trained pre- adolesents and untrained, but normally active counterparts in physical working capacity , body composition and blood lipids. The study hypotheses were that the trained subjects would have a lower mean body fat percentage, lower...
Lagrangean relaxation is presented as a solution
technique to solve flow constrained area-based harvest
scheduling problems. The best set of multipliers in the
Lagrangean approach is obtained through the subgradient
method. Guidelines to set some parameters to compute the
step size in the subgradient algorithm are provided. An
additional procedure...
YBa₂Cu₃0₇₋x was doped with In by a stoichiometrically exact substitution of
Y by In, doping levels ranging from 0% to 20%. Room temperature X-ray diffraction
measurements, Perturbed Angular Correlation spectroscopy using ¹¹¹Cd as nuclear
tracer at a variety of temperatures ranging from room temperature to 950°C and magnetic
flux exclusion...
High concentrations of the fumigant methylisothiocyanate (MITC) will effectively control decay fungi in large wood structures, but the fungitoxicity of low MITC concentrations and the influence of wood moisture content (MC) on its performance are not well understood. The MC of Douglas-fir heartwood greatly influenced the susceptibility of the decay...
Douglas-fir, Pseudotsuga menziesii and white alder,
Alnus rhombifolia, species that are prevalent in the
Pacific Northwest, were fed to larvae of the gypsy moth,
Lymantria dispar L. Gypsy moth larvae from different
familial lines (egg masses) from a single geographic
population were evaluated on these hosts. The larvae
were fed...
