Aspects of the autecology of the plethodontid salamander, Aneides ferreus (Cope)

Creator:: McKenzie, Donald Samuel
Abstract:: Laboratory experiments and simulated field conditions were utilized to gain a better understanding of the ecology of the clouded salamander. Animals collected in western Oregon were utilized for studies in habitat selection, where it was shown that there was a significant pattern of selection of litter types (rock, bark, and...

Symmetry allowed charge-transfer transitions between spin-orbit states in the gaseous dihalides of Mn, Co, Ni, and Cu

Creator:: Konopka, Ronald Francis
Abstract:: The spin-orbit states of both the ground and several charge-transfer-excited electronic configurations of gaseous MnX₂, CoX₂, NiX₂, and CuX₂ are derived. Only one-electron transitions from the ground electronic state are considered. The molecules are treated as linear in both the ground and excited states. In each case, the spin-orbit states...

Ecology of benthic microalgae of estuarine intertidal sediments

Creator:: Riznyk, Raymond Zenon
Abstract:: The benthic microalgae of sediments of the two tidal flats in Yaquina Bay, Oregon were investigated to determine the environmental factors limiting the abundance and the horizontal and vertical distribution of these organisms. The Southbeach tidal flat which is under the marine realm of deposition consists of fine to medium...

Methanolysis of tetrakis(trichlorophosphine)nickel(0)

Creator:: Bachman, David Franklin
Abstract:: The methanolysis of phosphorus trichloride coordinated to nickel (0) has been studied. Free phosphorus trichloride reacts with methanol to give dimethyl hydrogen phosphonate, methyl chloride, and hydrogen chloride. The reaction involves a rearrangement on phosphorus using the lone pair, in which the coordination number increases from three to four. In...

Seed dormancy, germination and seedling vigor of some Kentucky bluegrass (Poa pratensis L.) varieties as affected by environmental and endogenous factors

Creator:: Maguire, James Dale
Abstract:: Seed of Cougar and Newport Kentucky bluegrass (Poa pratensis L.) was harvested at Pullman and Spokane at several stages of maturity. Variations in seed attributes resulting from environmental and maturity effects were evaluated through germination tests, tetrazolium staining, seed moisture and seed weight determinations. Seedling vigor was determined by .speed...

A comparison of the inductive and deductive group approaches in teaching selected phonic generalizations to second grade children

Creator:: Britton, Gwyneth E., 1935-
Abstract:: The purpose of this study was to answer three questions in terms of learning methodology: (1) Is the inductive or deductive approach more effective in teaching phonic generalizations to second grade children? (2) Is the inductive or deductive approach more effective in promoting retention ability after a three week interim?...

A study of the biosynthesis of sterols and related compounds by a bovine aorta preparation

Creator:: Walsh, Marilyn Ruth
Abstract:: Previous investigations of the biosynthesis of sterols by the arterial wall have shown that the intact aorta is capable of low level incorporation of labeled precursor into a sterol digitonide. The biosynthesis of sterols and related lipids by a cell-free preparation of bovine aorta was investigated in the present study....

Manganese absorption by barley roots

Creator:: Maas, E. V. (Eugene Vernon), 1936-
Abstract:: An investigation of Mn uptake by five-day-old excised barley roots revealed that a metabolically-mediated process was involved. In short-term experiments, the rate of Mn absorption was comparable to that of the macronutrient cations. Like other metabolically absorbed cations, the Mn absorption rate was a direct function of the ambient concentration...

A comparative study of the in vitro localization of mercury from phenylmercuric acetate and mercuric salt in rat kidney and liver subcellular fractions and their effect on alkaline phosphatase

Creator:: Massey, Thomas H.
Abstract:: Studies were undertaken to determine the extent and rate of binding of Hg-203 labeled phenylmercuric acetate and mercuric ace tate in rat kidney and liver slices and their subcellular fractions after 37°C incubation of the slices in Krebs-Ringer -phosphate solutions containing the mercurials at 10⁻⁴ molar. A fast and parallel...
