A three-dimensional model based on fundamental principles to simulate heat and mass transfer and mat densification during hot pressing of wood-based composites is presented. Mechanisms included in the analysis are wate ...

A hypothesis used to explain the relationship between timber harvesting and landslides is that tree roots add mechanical support to soil, thus increasing soil strength. Upon harvest, the tree roots decay which reduces ...

Automated size exclusion chromatography with a differential refractometer detector was employed to study the molecular weight distribution patterns in various types of wood pulp cellulose. The results obtained were cor ...

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 a ...

I studied riparian forests of four western Oregon watersheds (dry south to wet north) to determine the multiscale controls on woody riparian vegetation. I conducted separate analyses of controls on plant distribution, di ...

The algorithm RLS-PLUS was developed to yield solutions to the multivariate control problem of diameter and species optimization for mixed conifer and hardwood stands. The problem is specified with twenty-five state va ...

A greenhouse bioassay was used to compare ectomycorrhiza formation and diversity in soils from undisturbed and clearcut and burned areas in moist mesic, moist montane and dry montane forest types representing a gradi ...

The response to various levels of stand density by natural Douglas-fir regeneration, shrub and sprouting hardwood species was studied in the mixed-evergreen-forests of southwest Oregon. Partial-cut old growth (harveste ...

White pitch deposits originated from the wood extractives, synthetic polymers, and additives used in the papermaking process, etc. may cause numerous problems to the papermaking process and also degrade the product qu ...

Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability eithe ...
