A Study to Determine the Effectiveness of Polyethylene Glycol 1000 for Forming Wood Veneer Projects from Green Lumber

Description: The problem was to determine the effectiveness of using polyethylene glycol 1000 in the treatment of green wood for the purpose of forming projects made of wood veneer and of simple design for use in junior high or high school woodworking classes. The purpose of this study was to seek answers to the following questions. 1. Is polyethylene glycol 1000 an effective stabilizing agent for green wood veneer that can be used in school woodworking classes? 2. Can green wood veneer treated with polyethylene glycol 1000 be bent to form simple woodwork projects? 3. Can green wood veneer treated with polyethylene glycol 1000 be successfully used in junior high and high school woodworking classes? 4. What length of treatment time is best for green wood veneer that is to be used to form simple bent wood projects? 5. Is one-fourth inch thickness suitable for green wood veneer that is to be treated with polyethylene glycol 1000 and used to form simple bent wood projects?

The Formulation of Wood Stain Solvents and Color Formulas Suitable for Use in the School or Home Laboratory

Description: The problem with which this study was concerned was that of developing wood stain formulas from a small supply of materials. These formulas should produce a wide variety of colors from which to select, the use of which should be suited to the school or home laboratory.

To Determine as Many Distinguishing Characteristics as Possible of Wood-Carving Designs of Other Nations

Description: The purpose of this study is to determine the characteristic wood-carving designs of England, France, Italy, Germany, and China. It attempts to present the findings in a form which will be of assistance to both college and public school teachers of wood-carving and to aid in classification of typical types of furniture.

Molecular Phylogeny and Evolution of the American Woodrats, Genus Neotoma (Muridae)

Description: The evolutionary relationships of woodrats (Neotoma) were elulcidated through phylogenetic analyses of mitochondrial DNA restriction site and allozyme data. DNA samples from eleven nominal species from the genus Neotoma and two outgroup taxa, Ototylomys phyttotis and Xenomys nelsoni, were cleaved using a suite of 17 Type II restriction endonucleases. Mitochondrial DNA restriction profiles were visualized following electrophoresis of restriction digests via methods of Southern transfer and hybridization with 32P- and digoxigenin-labeled mtDNA probes. Restriction mapping resulted in the identification of 37 unique mtDNA haplotypes among the woodrat taxa examined. Proteins representing 24 presumptive structural gene loci were examined through starch gel electrophoresis. Binary-coded allozyme data and allozyme frequency data were analyzed using PAUP and FREQPARS, respectively. Phylogenetic analyses of the mtDNA restriction site data incorporated three different character type assumptions: unordered binary characters, Dollo characters, and differentially weighted unordered characters employing the STEPMATRIX option of PAUP. Proposed phylogenies for Neotoma are based on majority-rule consensus trees produced using bootstrap procedures. Phylogenetic analyses of the woodrat data sets revealed a distinct dichotomy among populations of white-throated woodrats (N. albigula) suggesting the presence of cryptic species within that taxon. MtDNA and allozyme data support the specific status of N. devia as distinct from N. lepida, and additionally reveal the presence of a third cryptic species referable to N. intermedia among the desert woodrats. Phylogenetic analyses of the genetic data also suggest subgeneric status for the desert woodrats, which is in agreement with evidence from morphology. The genetic data revealed a sister group relationship between N. stephensi and samples of N. mexicana, suggesting the placement of N. stephensi into the N. mexicana species-group. Neotoma fuscipes and N. cinerea formed a monophyletic lineage basal to the remaining members of the subgenus Neotoma which supports the assignment of N. fuscipes to the subgenus Teonoma with ...

Alaska Wood Biomass Energy Project Final Report

Description: The purpose of the Craig Wood Fired Boiler Project is to use waste wood from local sawmilling operations to provide heat to local public buildings, in an effort to reduce the cost of operating those buildings, and put to productive use a byproduct from the wood milling process that otherwise presents an expense to local mills. The scope of the project included the acquisition of a wood boiler and the delivery systems to feed wood fuel to it, the construction of a building to house the boiler and delivery systems, and connection of the boiler facility to three buildings that will benefit from heat generated by the boiler: the Craig Aquatic Center, the Craig Elementary School, and the Craig Middle School buildings.

Supplies and production of aircraft woods

Description: The purpose of this report is to present in brief form such information as is available regarding the supplies of the kinds of wood that have been used or seem likely to become important in the construction of airplanes, and the amount of lumber of each species normally put on the market each year. A general statement is given of the uses to which each kind of wood is or may be put.
