The Chugach National Forest has been using prescribed fire as a wildlife habitat management tool since l977. Between 1977 and 1997 about 4,000 hectares have been burned on the Kenai Peninsula to promote regeneration of woody plant species used by moose (Alces alces). Browse species include paper birch (Betula papyrifera),...
Large inelastic strain occurs inside a piece of lumber during drying. The strain consists of several components such as elastic, plastic, creep, shrinkage and mechano-sorptive effect. The mechanical behavior of the whole board during drying is determined by the behavior of individual strain components and their interactions. Whereas limited investigations...
Studies in the lower Lookout Creek-Blue River area have revealed a geomorphic history including glaciation and the development of three alluvial surfaces, presently active alluvial cones and older, deeply dissected cone remnants. Results are based on landform mapping, analysis of the types and distributions of surficial sediments, and the
distribution...
New sources of genetic diversity must be incorporated into plant breeding programs if they are to continue increasing grain
yield and quality, and tolerance to abiotic and biotic stresses. Germplasm collections provide a source of genetic and
phenotypic diversity, but characterization of these resources is required to increase their utility...
The influence of substrate and enzyme concentration on the rate
of saccharification of two defined, insoluble, cellulose substrates,
Avicel and Solka-Floc, by the cellulase enzyme system of Trichoderma
viride has been evaluated. Assays utilized enzyme concentrations
ranging from 0.014 to 0.056 filter paper unit per mL and substrate
concentrations up...
Landslides are an insidious natural hazard, which can result in significant damage to public infrastructure. Limited monitoring tools are available, particularly tools suitable for use in forested environments. These tools often only allow a few locations across the slide to be monitored. Terrestrial Laser Scanning (TLS) shows promise as a...
With the growing trend in use of 3D laser scanning technology for data collection, it is important to study the various potential applications of this revolutionary technology. One such application is the measurement of road roughness at both large and small scales. At larger extents, terrestrial laser scanning (TLS) is...
Terrestrial Laser Scanning (TLS) is an efficient, effective, and precise measurement tool rapidly growing in popularity in a wide variety of fields. Use of TLS data often requires aligning multiple scans for a more complete model of a scene or object, a procedure known as scan registration. Each scan setup...
Many performance tuning tools for parallel software use visual representations of trace data to guide a developer towards code improvements. Most widely used visualization schemes, however, either omit useful information about time dependence of processor use, or include that information but do not scale well to long run times or...
Falls in older adults are an important concern due to the potential injuries associated with falling. Decreases in muscle strength as a result of natural aging could impair the ability of older adults to prevent either a backward or forward fall. Two musculoskeletal models were used to predict the effect...
