The influence of ionizing radiation, photoperiod, and environmental temperature on cell proliferation in the intestinal epithelium of the rough-skinned newt (Taricha granulosa)

Creator:: Filipy, R. E.
Abstract:: Kinetics of cell division in the intestinal epithelial proliferative cells (cell nests) of the rough-skinned newt, Taricha granulosa, were studied using tritiated thymidine autoradiography and the mitotic arresting properties of colcemid. Percent labeled mitoses (PLM) curves were drawn from the autoradiographic data from two separate experiments in which the newts...

Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

An assessment of rival British theories of biogeography, 1800-1859

Creator:: Kinch, Michael P.
Abstract:: At the beginning of the nineteenth century most theorizing British naturalists supported a Biblical account of the distribution of life which was based upon the notion that life had been dispersed from the resting place of the ark. This implied a relatively even dispersion of life about the Earth, but...

Aspects of the geographic ecology of the Acorn Woodpecker (Melanerpes formicivorus)

Creator:: Doerge, Katherine Fortner
Abstract:: Population and habitat characteristics of Acorn Woodpeckers (Melanerpes formicivorus) were examined in oak stands (Quercus garryana) in Benton County, Oregon. Characteristics of eight oak stands not containing Acorn Woodpeckers were also examined. The data were used to determine which factors might be related to woodpecker presence and abundance within the...

John Turberville Needham (1713-1781) and eighteenth century theories of generation

Creator:: Benson, Keith Rodney
Abstract:: There were two viable theories of generation, preformation and epigenesis, existing in the Seventeenth and Eighteenth Centuries. Due to their irreconcilable nature, they were often at loggerheads during this time interval. The status of these generation theories can be effectively understood in terms of Thomas Kuhn's conception of preparadigm science....

Reactions of the sea anemone, Anthopleura xanthogrammica, to electromagnetic radiations in the visible, ultraviolet, and X-ray ranges

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...

The Oregon eugenic movement : Bethenia Angelina Owens-Adair

Creator:: Currey, Linda Lorraine
Abstract:: In 1906, applying Charles Darwin's evolutionary theories to the human race, Sir Francis Galton introduced the concept of eugenics, "the science of the improvement of the human race by better breeding." The rediscovery in 1900 of Mendel's laws of genetic inheritance and an upsurge in hereditarian thought set the stage...

Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

Creator:: Chorzempa, Mary André, Sister
Abstract:: Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...

Denison Olmsted (1791-1859), scientist, teacher, Christian : a biographical study of the connection of science with religion in antebellum America

Creator:: Schoepflin, Gary Lee
Abstract:: A biographical study of Denison Olmsted, focusing upon his own Christian world view and its connection with his various activities in science, supports the view that religion served as a significant factor in the promotion of science in America during this time period. Olmsted taught physics, meteorology and astronomy at...
