Methylisothiocyanate as a wood fumigant : fungitoxicity to Poria carbonica in wood and gelatin encapsulation for use in wood products

Creator:: Zahora, Andrew Roy
Abstract:: Experiments were conducted to determine both the influence of wood moisture content on the fungitoxicity of methylisothiocyanate (MIT) to the wood-decay fungus Poria carbonica, and the ability of gelatin to safely en-capsulate MIT for efficient treatment of wood products. The fungitoxicity of MIT was studied by determining the product of...

Interactions of the fumigant methylisothiocyanate with Douglas-fir wood and their influence on fumigant effectiveness

Creator:: Zahora, Andrew Roy
Abstract:: Experiments investigated how the fumigant methylisothiocyanate (MIT), Douglas-fir wood at various moisture contents (MC), and the wood decay fungus Poria carbonica Overh., interacted to govern overall fumigant effectiveness. MIT decomposed in wood to form non-MIT residues at rates of about 0.16%, 0.9%, and 1.6% of the total bound MIT per...

The influence of wood moisture content on the fungitoxicity of methylisothiocyanate in Douglas-fir heartwood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: 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...

A Note on the Sensitivity of A Closed-Tube Bioassay To Volatile Methylisothiocyanate Residues In Fumigant-Treated Wood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: A closed-tube bioassay with Poria placenta was used to measure residual fungistatic vapors in wood fumigated with methylisothiocyanate (MIT). This bioassay showed an inverse linear relationship between fungal growth and the amount of MIT in the wood samples. For fumigated increment-core sections of unseasoned Douglas-fir heartwood (4.8 mm in diameter...

Diffusion and sorption of the fumigant methylisothiocyanate in Douglas-fir wood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: The influence of moisture content (MC) and conventional preservative treatment on methylisothiocyanate (MIT) sorption and diffusion were investigated in Douglas-fir wood. In wood at 0% MC, the ratio of equilibrium MIT adsorption to desorption concentrations was low (0.2), but it increased rapidly to about 0.94 above 18% MC. Partition coefficients...

Water residence time and runoff generation in the western Cascades of Oregon

Creator:: McGuire, Kevin J.
Abstract:: The age, or residence time of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways and source of water in a single integrated measure. While there has been tremendous recent interest in residence time to characterize catchments, there are few studies that quantify residence...

Performance analysis of network based file systems

Creator:: Garimella, Krishna S.
Abstract:: The performance of multi-user workstations that access files over a local area network is studied. Such file systems, called distributed file systems, provide access of remote file systems with a great degree of transparency. The main objectives are To study the principles of distributed file systems. specifically NFS from Sun...

Comprehensive multiyear carbon budget of a temperate headwater stream

Creator:: Argerich, Alba, Haggerty, Roy, Johnson, Sherri L., Wondzell, Steven M., Dosch, Nicholas, Corson-Rikert, Hayley, Ashkenas, Linda R., Pennington, Robert, and Thomas, Christoph K.
Abstract:: Headwater streams comprise nearly 90% of the total length of perennial channels in global catchments. They mineralize organic carbon entering from terrestrial systems, evade terrestrial carbon dioxide (CO₂ ), and generate and remove carbon through in-stream primary production and respiration. Despite their importance, headwater streams are often neglected in global...

An efficient data transfer protocol for Ethernet

Creator:: Hegde, Anoop R.
Abstract:: Most general purpose protocols are found to suffer from inefficiency in an Ethernet LAN environment when used for large volume data transfer. This is especially true with the TCP/IP family which was designed for a wide area network. This research work presents a proof of this inefficiency and proposes a...

A graphical ethernet monitoring system (GEMS)

Creator:: Park, Chung Min
Abstract:: GEMS (Graphical Ethernet Monitoring System) is an enhancement to the SU-PC/IP NETWATCH program, for the graphical display and recording of computer network packets. SU-PC/IP (Stanford University Personal Computer/Internet Protocol) NETWATCH displays one line of information per packet, including the packet type, IP addresses, packet size, and protocol type, etc. This...
