The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...
Nanostructured material has been projected to be the next generation material for the detection of ionizing radiation due to the uniquely superior physical processes associated with charge creation and by virtue of their optoelectronic tunablility. Semiconducting Nanocrystal (NC) detectors, by nature of their low band gap material, low fabrication costs,...
Satellite imagery has become an efficient and time effective tool that
may aid in the development of regional terrestrial and aquatic resource management
schemes. A methodology utilizing National Oceanic and Atmospheric
Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR)
imagery, 1.1 kilometer spatial resolution at nadir, was developed for delineating...
Understanding how the latitudinal distribution of methane sources changed between stadial and interstadial climate states during the last glacial period can provide important clues about how terrestrial hydroclimate and ecosystems evolved between these different states. The punctuation of the millennial-scale structure by Heinrich events is also of interest in this...
The objective of this study was to identify the varying effects of altering the rumen fluid: substrate ratio on the outcomes of in vitro rumen fermentation. In vitro fermentation is a useful tool for evaluating the energy value of feedstuffs and the effect of feed additives on Volatile Fatty Acid...
The objectives of this study were to determine the diets of
cattle at risk to DABPE on stress and inciting pastures and to determine
if segregated feeding groups of cattle displayed differential
susceptibility to DABPE.
Stress pastures were classified and mapped by plant communities
and segregated feeding group areas. Cattle...
In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...
A major challenge to the study of the peopling of the Americas is that much of the Bering Land Bridge (Beringia), the geographic area that people migrating from Northeast Asia into North America would presumably have passed through, is now submerged due to sea-level rise since the last glacial maximum....
In the highly alkaline environment of concrete, carbon steel rebar is protected against corrosion by a passive oxide/oxyhydroxide film. Understanding the characteristics of this passive film, and how it depassivates, is the key for mitigating problems associated with steel corrosion in concrete. Although a large number of electrochemical and analytical...
A Digital Earth is a visualization tool that uses the latest technologies to embed vast
quantities of geographic data into easily understood information. By creating three-dimensional
landscape visualizations that look as photorealistic as current technology
allows, it becomes possible to see, explore, and spatially understand parts of the Earth as...
