Decomposition of metham sodium to methylisothiocyanate as affected by wood species, temperature, and moisture content

Creator:: Morrell, Jeffrey J.
Abstract:: The effect of various wood characteristics on decomposition of metham sodium to methylisothiocyanate in sixteen North American and Southeast Asian hardwoods and softwoods was investigated. While marked differences were noted in the degree of decomposition among some species, the relationship between decomposition and lignin content, extractive levels, wood pH, or...

Occurrence of preservative-treated wood in a wood recovery center in Western Oregon

Creator:: Morrell, Jeffrey J.
Abstract:: The amounts of treated wood present at a wood recycling center in western Oregon were surveyed over a 10-year period. Treated wood was found at 106 of 112 inspections, but the levels never exceeded 2 percent of the volume present. The amount of treated wood averaged 0.15 percent of the...

Resistance of Selected Wood-Based Materials to Fungal and Termite Attack in Non–Soil Contact Exposures

Creator:: Morrell, Jeffrey J.
Abstract:: The resistance of three naturally durable heartwood species and a stranded giant bamboo product to fungal and termite (Coptotermes formosanus) attack was evaluated at a test site located near Hilo, Hawaii. Merbau (Intsia bijuga or I. palembanica) and ipe (Tabebuia spp.) were both exceptionally resistant to fungal and termite attack,...

Bioassaying wood preservatives with Aspergillus niger

Creator:: Morrell, Jeffrey J.
Abstract:: The bioassay with Aspergillus niger is a simple way of determining the presence and amount of pentachlorophenol or tributyltin oxide in wood, but it does not appear useful for measuring strongly fixed chemicals such as chromated copper arsenate, borate, and fluoride. Its effectiveness in detecting other preservatives has not been...

On the Economics of Virtual Water Trade

Creator:: Reimer, Jeffrey J.
Abstract:: Virtual water trade is increasingly recognized as a useful metaphor for thinking about freshwater resources in an international context. Its legitimacy in terms of economic theory has been questioned by a number of authors, however. In this article I develop new theoretical results that place the virtual water concept on...

Impacts of disturbance on the terrestrial carbon budget of North America

Creator:: Kasischke, Eric S., Amiro, Brian D., Barger, Nichole N., French, Nancy H. F., Goetz, Scott J., Grosse, Guido, Harmon, Mark E., Hicke, Jeffrey A., Liu, Shuguang, and Masek, Jeffrey G.
Abstract:: Because it is an important regulator of terrestrial carbon cycling in North America, extensive research on natural and human disturbances has been carried out as part of the North American Carbon Program and the CarboNA project. A synthesis of various components of this research was carried out, and the results...

Fourfold amplification of solitary-wave Mach reflection at a vertical wall

Creator:: Knowles, Jeffrey and Yeh, Harry
Abstract:: With the use of a higher-order Euler formulation, we numerically study the reflection of an obliquely incident solitary wave at a vertical wall and compare results with the higher-order Kadomtsev-Petviashvili theory. A maximum amplification of 3.91 is achieved along the wall, nearly realizing the fourfold prediction by Miles (J. Fluid...

Production of fungal protoplasts from selected wood-degrading fungi

Creator:: Rui, Chen and Morrell, Jeffrey J.
Abstract:: Studies of the effects of various chemicals on fungal growth are difficult to perform on filamentous fungi because of the difficulty of observing the protoplasm through the rigid hyphal wall, and because most activity occurs in the region near the hyphal tip. However, hyphae can be exposed to certain enzymes...

Assessing Biocide Effects on Protoplasts of Wood Decay Fungi

Creator:: Rui, Chen and Morrell, Jeffrey J.
Abstract:: Hyphal fragments and protoplasts of two wood-degrading fungi, Postia placenta and Trametes versicolor, were used to examine the effects of two fungicides, copper sulfate and azaconazole, on fungal health (as measured by oxygen consumption, glucose utilization, potassium levels, cell regeneration, and copper uptake). Although both cell systems responded to the...
