Creator:: Clark, Ervil Delwyn
Abstract:: The behavioral repertoire of the sea anemone, Anthopleura xanthogrammica, was investigated to test for the occurrence of any immediate response to various regions of the electromagnetic spectrum. Monochromatic radiations in the visible and ultraviolet spectral regions were produced by a 150-watt xenon lamp or a ZOO watt mercury vapor lamp...

Creator:: Terhune, James Albert
Abstract:: The purpose of this study was to investigate the relationships between age, sex, eye-hand coordination, the time it takes individuals to learn how to manipulate dental floss between all of their teeth, and the time it takes individuals to learn how to effectively clean their teeth with dental floss. The...

Creator:: Sullivan, Timothy Joseph
Abstract:: Research has been completed which identifies qualitatively and quantitatively the deposition, persistence and fate of polynuclear aromatic hydrocarbons (PNAH) on burned clear-cut sites in Oregon. Eight PNAH were identified and quantified in post-burn litter samples taken from four slash-burned sites. Deposition of lower molecular weight, 3-4 ring compounds was considerably...

Creator:: Ray, Brian Daniel
Abstract:: The purpose was to gain information about the determinants of student behavior with respect to laboratory (lab) and non-laboratory (non-lab) science learning activities. Fishbein and Ajzen's (1975) theory of reasoned action was used to investigate students' salient beliefs, correlations between determinants of intention, and the relative weights of determinants of...

Creator:: Becerra, Michael A.
Abstract:: Rats exposed to one or two doses of 60 mg mirex/kg by gavage exhibited hypertrophied livers and various degrees of hepatobiliary dysfunction. Although single dosed animals demonstrated elevated whole liver bile flow after 96 hours, the single dose was insufficient to significantly inhibit whole liver hepatobiliary performance as measured by...

Creator:: Minear, Paula J.
Abstract:: This study examined channel structure and position and riparian vegetation and land use on the upper 70 km of the McKenzie River, Oregon in the 1940s, compared the 1940s conditions to present conditions, and explored the processes driving change in this system and the implications for aquatic habitat. The hydrologic...
Resource Type:: Masters Thesis

Creator:: Velazquez-Martinez, Alejandro
Abstract:: The objectives of this research were to study: a) the effect of thinning and treatments consisting of pruning and multinutrient fertilization on aboveground biolnass increment, growth efficiency (GE), and foliar nutrients; b) the influence of topoedaphic variables (soil nutrients, slope, aspect, and rock content) and foliar nutrients on both leaf...

Creator:: Whiting, Mark Carlos
Abstract:: Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...
