Little Smalltalk is a small, reasonably fast, easy-to-understand, easy-to-modify Smalltalk system. The system was originally developed in 1984 as a part of an implementation project to develop a minimal Smalltalk system, closely resembling Smalltalk-80. The system was developed in C. The current project is an experiment to port the Little...
The purpose of this study was to examine the relationship between inactive older adults’ physical activity readiness (based on the Physical Activity Readiness Questionnaire [PARQ]) and several biometric, demographic, and physical activity indices. Participants were 181 (91 female, 90 male) inactive 60- to 89-year-old adults (M age = 70.2 ±...
Sloping interfaces of fine over coarse porous material have been considered for use as barriers to infiltration for many years. Previous literature has developed analytical solutions for flow over such interfaces, numerical simulation of such flow, and the effects of anisotropy on the diversion capacity of such a system. In...
A slope stability map is created for the Astoria Basin, northwestern Oregon. The stability analysis is based upon a topographically based model, TOPOG model. The model predicts the occurrence of subsurface water-logging which reduces the shear-strength of a slope-profile. Simply stated, subsurface saturated zones occur wherever the local drainage flux...
Because irrigation can overcome reliance on rainfall, in the past 40 years the majority of peppermint acreage has moved to irrigated regions of the Pacific Northwest.
Pole-size Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were inoculated with two fungi (Ophiostoma pseudotsugae (Rumb.) von Arx and Leptographium abietinum (Peck) Wingf.) associated with the Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) to evaluate their pathogenicity. Pruning the lowermost 30% of the live crown had no
effect on host tree defenses. Inoculation with...
Pollen contamination was investigated in one block (block 4) of a 10-block Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard complex in western Oregon. Blocks (25 clones each) represent different breeding zones; thus, contaminant pollen sources not only included the adjacent natural stand of Douglas-fir, but also other blocks within the...
Six 40-year-old red alders (Alnus rubra Bong.) were harvested from a mixed stand of A. rubra and big-leaf maple (Acer macrophyllum Pursh) in the Oregon Coast Range to evaluate variation in their wood characteristics at two heights. Because the trees had a slight lean (4 to 14°), we sampled along...
