The dynamics of N was studied in field grown Comice/Provence
quince BA29 pears in Medford, Oregon. Total tree biomass, N content,
and ¹⁵N evaluations suggest that young pears require little N (48 kg
N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was
remobilized into new...
L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...
Iodine-129 is a key risk driver at sites where nuclear materials have been fabricated or processed, and it is a predominant isotope of concern in long-term waste storage strategies. I-129 exists primarily as iodate in the subsurface at the Hanford Site in south-central Washington State. Between 15 and 40% of...
Research indicates that child sex abuse contributes to emotional and behavioral
dysfunction in adult survivors. However, no one factor within the abuse experience has
been found to independently affect adult functioning, and it is unclear if several factors
acting together influence degree of dysfunction. This study compared the Global
Assessment...
In general, making optimal decisions is a never ending challenge that decision makers face. A comprehensive model that integrates decisions at all three levels of decision making (i.e., strategic, tactical, and operational) can help the decision maker to find solutions that best serve the organization's performance. However, as organizations expand...
Inheritance of eight enzyme systems, alanine aminopeptidase (AAP), aspartate
aminotransferase (AAT), aconitase (ACON), glucose phosphate isomerase (GPI),
malate dehydrogenase (MDH), 6-phosphogluconate dehydrogenase (6-PGD),
phosphoglucomutase (PGM), and shikimate dehydrogenase (SDH) was studied in
hazelnut (Corylus avellana L.) by either polyacrylamide gel electrophoresis
(PAGE) or starch gel electrophoresis. Three isozymes were detected...
