Plate loading tests in rock are deceptively simple tests to perform.
Consequently, many varieties have been developed in the past
60 years. From each of the varieties various investigators have added
their own developments and modifications, some good, and some not so
good. The result has been a confusion of...
Three studies on Douglas-fir beetle (DFB), Dendroctonuspseudotsuae, were conducted to investigate its basic and applied biology. Studies included investigations into the spatial relationship of DFB infestations over multiple years and multiple landscapes, relationships between DFB brood adult lipid levels and position of development along the length of tree boles, and...
Monitoring the sources and fate of freshwater in the
East Greenland Current (EGC) is important, as this water
has the potential to suppress deep convection in the Nordic
and Labrador Seas if the outflow of freshwater from the
Arctic Ocean increases in response to climate change. Here,
hydrographic, oxygen isotope...
Within the United States, the number of "out" Lesbian, Gay, and Bisexual (LGB) individuals attending a college or university is on the rise (Rosario, Schrimshaw, Hunter & Braun, 2006). With this increase, the new and/or different ways that lesbian and gay individuals can present and express their sexual orientation has...
An examination of the technical and historical literature
concerning the discovery and development of antibiotics suggests the
possible existence of an era of discovery. This era appears to have
a well-defined beginning (about 1940) and a well-defined close (about
1960). It is the purpose of this dissertation to examine the...
Samarium-neodymium data for authigenic ferromanganese
sediments from the oceans indicate that the Atlantic, Pacific, and
Indian Oceans each have a distinct range in Nd isotopic composition,
all of which are far less than ¹⁴³Nd/¹⁴⁴Nd ratios of source rocks with
oceanic affinities. Direct measurements of the Nd isotopic composition
of seawater...
Centuries of continuous grain cropping in northern Africa have
reduced N levels in soils to a degree such that agricultural production
is now largely dependent upon nitrogen fertilizer. Through the
identification of highly effective legume and Rhizobium strain combinations,
the production of protein-rich livestock forage and green
manure can be...
This thesis asserts that faculty are the critical resource for the integration of distance
education by postsecondary institutions. The major barriers to the participation and
adoption of distance education center around faculty. This manuscript thesis incorporates a
series of articles to develop applied frameworks and strategies that place faculty at...
Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...
