Seasonal pattern of secondary growth in stems of northern white spruce (Picea glauca (Moench) Voss)

Creator:: Gregory, Robert A.
Abstract:: Cambial activity in white spruce stems in Alaska was observed from April, 1964 to September, 1965 in over 300 samples taken from 50- to 60-year-old natural stands. Mitotic index was used as a measure of the rate of periclinal division of fusiform cells in the cambial zone. Anticlinal divisions are...

The uptake, transformation, and physiological response of the marine red macroalga Portieria hornemannii to the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT)

Creator:: Cruz-Uribe, Octavio T.
Abstract:: The capability of the marine red macroalga Portieria hornemannii to remove and detoxify the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT) in a seawater environment was evaluated using an axenic microplantlet suspension culture system. Microplantlets were challenged with TNT dissolved in seawater at concentrations of 1 to 50 mg L-1 in well-mixed photobioreactors...

Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

Creator:: Gestson, Sean Lyle
Abstract:: Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

Adrenergic receptors for glycogenolysis and cardiac contractile force

Creator:: Griffin, Claude Lane
Abstract:: It is common to characterize adrenergic receptors by placing them in one of two categories, alpha or beta. The receptors responsible for adrenergically induced increase in cardiac contractile force and glycogenolysis are usually classified as beta receptors, but such a classification is not definitely established. Therefore, an attempt was made...

The economics of land gains taxation : the Vermont case

Creator:: Daniels, Thomas L.
Abstract:: Governments have employed special capital gains taxes to curb speculation in real estate and raise public revenue. Economic theory suggests that the introduction of a gains tax with a declining rate structure over time will induce prospective buyers to reduce their demand for land and will induce sellers to offer...

Conversion of biomass constituents to hydrogen-rich gas by supercritical water in a microchannel reactor

Creator:: Goodwin, Aaron K.
Abstract:: Microreactors offer high rates of heat transfer able to intensify highly endothermic biomass reforming reactions in supercritical water. In this study, two continuous flow microreactor configurations were used to gasify biomass constituents in supercritical water. The first reactor configuration was a micro diameter stainless steel or Hastelloy tube (508 µm...

Riparian and adjacent upslope beetle communities along a third order stream in the western Cascade Mountain Range, Oregon

Creator:: Brenner, Gregory John
Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...

An investigation of the absorption spectra of EGTA metal complexes and the development of spectrophotometric methods for the analyses of copper, erbium, europium, holmium, neodymium, and praseodymium

Creator:: Holmes, Ivan Gregory
Abstract:: The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)] tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions. The absorption spectra of the chelates formed were measured with a recording spectrophotometer between 200 and 700 mμ. The pH of each solution was varied and a spectrum was scanned...

Effects of light, nutrients, and grazing on periphyton communities in streams

Creator:: Gregory, Stanley Vincent
Abstract:: Relative effects of light, nutrients, and grazing on primary production were investigated in streams in the Cascade Mountains of Oregon and in laboratory streams. Relative magnitudes of primary production and associated processes were examined for one year in a stream that flowed through a clearcut and an old-growth forest in...

Pheromonal mediation of reproductive behavior in the brown tree snake

Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...
