Chemical and physical influences of the atmosphere upon the spatial and temporal characteristics of atomic fluorescence in laser microprobe plumes

Creator:: Lewis, Arnold Leroy
Abstract:: The temporal and spatial characteristics of the plume produced by a laser microprobe, are dependent upon the composition and pressure of the atmosphere surrounding it. It has been shown that certain atmospheres can enhance the analytical signal by increasing the free atom lifetime. Improvements were made to the existing laser...

Senftenbergia oregonensis (Arnold) comb. nov. (Filicales): Delimiting Relationships Among Paleozoic Tedeleaceae

Creator:: Hillier, Kaitlin G. and Rothwell, Gar W.
Abstract:: Reexamination of fossilized plant material from the westernmost Pennsylvanian-age wetland flora in North America reveals that material of Pecopteris oregonensis Arnold represents a filicalean fern frond with annulate sporangia and anatomically preserved vascular tissues of the rachis. The frond, which is redescribed as Senftenbergia oregonensis (Arnold) Hillier et Rothwell comb....

Cyperus esculentus control with glyphosate : time of application and addition of ammonium sulfate

Creator:: Costa, Jaime
Abstract:: Cyperus esculentus L. var. esculentus is a serious weed problem in northwest Spain. Long-term control from glyphosate and other herbicides has been inconsistent. Field, greenhouse, and laboratory studies were conducted on factors influencing the activity of glyphosate on C. esculentus. In field studies, glyphosate controlled foliage growth at most growth...

Effect of a pre-irrigation period on the activity of ethofumesate applied to dry soil

Creator:: McAuliffe, David
Abstract:: Applications of ethofumesate in Oregon have been observed from previous research and from commercial use to be less effective when applied to dry soils, even if subsequent precipitation occurred within a few days. Two field studies were established in the summer of 1979 using sweet corn (Zea mays L. 'Jubilee')...

Application of algebraic topology to graphs and networks

Creator:: Gerlach, Siegfried
Abstract:: In this thesis some applications of algebraic topology are given. Kirchhoff's circuit laws are translated into the language of algebraic topology: If G is the graph of a network N, if i is a current distribution and if v is a voltage distribution of N, then the two Kirchhoff laws...

Stimulation of plant growth by sub-lethal concentrations of herbicides

Creator:: Wiedman, Steven John
Abstract:: Studies were conducted to determine the extent and nature of sub-lethal effects of herbicides on plant growth. At least one herbicide from each major chemical class of herbicides was evaluated under greenhouse conditions. Oat plants were grown in sand culture to eliminate soil interferences. Herbicides were applied pre-emergence in nutrient...

Naphthalene resistance in a house fly strain : its inheritance and characteristics

Creator:: Schafer, James Arnold
Abstract:: A combination of genetical and biochemical methods were utilized in investigating house fly resistance to naphthalene. The inheritance of resistance was determined by crossing a naphthalene resistant strain of Musca domestica L. with a susceptible mutant marker strain. Biochemical comparisons were made on substrains isolated from the progeny of these...
