Hypervelocity spectroscopy from impacts in polymeric materials

Creator:: Buettner, Douglas J.
Abstract:: Stacked sheets of polyethylene terephthalate andpolystyrene provide a means for recovering projectiles travelling at hypervelocities. The transparency of these multiple diaphragms is utilized so that light generated from hypervelocity impacts can be studied. A method for gathering visible as well as ultraviolet light from less transparent polymer foams has been...

Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Effects of physiological state upon nitrosoguanidine-mediated allelic recombination in Saccharomyces cerevisiae

Creator:: Buettner, Michael John
Abstract:: Saccharomyces cerevisiae strain XS-380, a. heteroallelic diploid strain, carries six genetically analyzed loci on the left arm of chromosome VII. Nitrosoguanidine (NMG) at low concentrations was observed to cause allelic recombination (either mitotic recombination or gene conversion) of the heteroallelic loci with low lethality. The NMG-inducible heteroallelic system was used...

Gut content analysis of juvenile shortnose suckers Chasmistes brevirostris Cope, 1879

Creator:: McDonald, Pat
Abstract:: Ontogenetic niche shifts are critical times in a fish's life that need to be passed for survival, growth and recruitment (Gerking 1994, Osenberg et al. 1994). These niche shifts are identified by a change in feeding from one prey type to another. These shifts in feeding occur throughout growth and...

Patterns of retention and vagrancy in larval Lost River and shortnose suckers from Upper Klamath Lake, Oregon

Creator:: Reithel, Susan A.
Abstract:: Larval transport and retention of two endangered suckers were studied in a highly altered lacustrine/riverine complex. The endangered populations of Lost River sucker, Deltistes luxatus, and shortnose sucker, Chasmistes brevirostris, in Upper Klamath Lake (UKL), Oregon are the largest remnant populations of these suckers. Downstream of UKL, the Keno Impoundment...

An evaluation of the use of tarif tables in second growth Douglas-fir

Creator:: Marshall, David D.
Abstract:: The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...

Age and growth of young-of-the-year Lost River suckers Deltistes luxatus and shortnose suckers Chasmistes brevirostris of Upper Klamath Lake, Oregon

Creator:: Logan, Daniel Joseph
Abstract:: Upper Klamath Lake in southern Oregon has two species of lacustrine suckers, Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris that were historically abundant. Results of surveys performed in the mid-1980's indicated that populations of both species were declining and ageing with apparent recruitment failure in most years...

Species identification of Klamath Basin suckers (Pisces : Catostomidae) and an assessment of hybridization using anonymous nuclear loci

Creator:: Wagman, David Wolfe
Abstract:: Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...

The chemistry and device applications of amorphous thin-film interfaces

Creator:: Knutson, Christopher C.
Abstract:: Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...
