The ~5 km3, 4.54 to 4.09 Ma Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex (APVC) of the Central Andes records the eruption of an andesite and two distinct rhyolitic magmas. It provides a unique opportunity to investigate the production of silicic magmas in a continental arc flare-up, where small volumes...
Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...
The purpose of this study was to provide exploratory understanding of the nature of academic prestige in the field of sociology, and to provide insights into the history of the discipline. The primary research question was: does academic prestige act as a factor in controlling academic knowledge production in the...
For decades, sexual violence has been a persistent crisis and challenge for universities and colleges across the United States. In order to address this problem and adhere to the strict legal obligations that require post-secondary institutions to prevent sexual violence on their campuses, universities and colleges have implemented a range...
The thesis area consists of 42 square miles located
in Madison and Gallatin counties, Montana, in the southern
part of the Madison Range. The strata exposed in the
area range in age from Precambrian to Quaternary and have
an aggregate thickness of more than 7,600 feet.
The Paleozoic rocks, about...
Land management policies are ideas about nature projected onto the landscape. Culminations of social, economic, and scientific influences, these policies create standards affecting the function of ecological systems. In the case of riparian lands in the Oregon Coast Range, policy requirements vary considerably across federal, state, and private land ownerships....
The morphology and genesis of soils of the Willamette series
and of some Willamette-associated soils and their relationships to
geomorphic surfaces were studied in an area near McCoy, Polk
County, Oregon. Influences of regional extent, such as climate and
parent material, were related to the soils and landforms. The soils...
This research has focussed upon both the in vitro and in vivo characterization
of the recycling pathway leading from 5'-deoxy-5'-methylthioadenosine
to methionine in fruit. In addition to contributing towards polyamine
biosynthesis and other important cellular functions, in plant tissues
these events also serve to generate the hormone ethylene. A broad...
The central focus of the present study was to assess the International Program (IP) and the Regular Thai Program at Satit Kaset in Bangkok, Thailand. The problem involved the gathering of both statistical and survey information from IP students, parents, and teachers in Grades 1-4 at the school. The primary...
