Airborne discrete-return lidar is an active remote sensing technology capable of obtaining accurate, fine-resolution three-dimensional measurements over large areas. Discrete-return lidar data produce three-dimensional object characterizations in the form of point clouds defined by precise x, y and z coordinates. The data also provide intensity values for each point that...
In the midst of the sixth mass extinction, understanding wildlife disease spillover is critical to maintaining protected wildlife areas. Studying ecoimmunology and wildlife disease ecology helps to understand immune and disease traits in an ecological context, which is invaluable in preventing pathogen spillover between livestock and wildlife. To investigate this...
The neurohypophysial peptide system is involved in modulating a
variety of physiological, neurological, and behavioral responses in
vertebrates. The principal forms of these peptides in non-mammalian
tetrapods are vasotocin (VT) and mesotocin (MT). The studies described
in this thesis used pharmacological, molecular, and biochemical
techniques, along with phylogenetic analyses, to...
Partitioning of trivalent actinides (in particular, americium and curium) from the
fission produced light lanthanides is a major concern of used nuclear fuel reprocessing for
the purposes of waste disposal. Several solvent extraction processes have been developed
to address these chemically difficult separations. The historically employed TALSPEAK
Process utilizes di-2-ethylhexyl...
In this dissertation, time-based signal processing techniques and their applications in oversampling and noise-shaping data converters are examined. These techniques demonstrate the ability to shift the burden of high performance analog circuits from the compressed voltage-domain to the augmented time-domain. First, the potential of high order noise-shaping and phase-domain feedback...
Relative lifetimes, and the closely related quadrupole moments (Q[subscript]i values), of the
six superdeformed (SD) bands in ¹⁹³Hg and the yrast SD band in ¹⁹²Hg were determined
by a Doppler-shift attenuation method measurement. The experiment was performed
using the Gammasphere array and Lawrence Berkeley National Laboratory's 88-inch
Cyclotron. The Q[subscript]i...
The studies presented here use the B- to Z-DNA transition and Z-DNA
crystallization as model systems to determine the contribution of solvent interactions to
macromolecular structures. The substituent groups of naturally occurring and modified
nucleotide bases affect the hydration and thus the stability of right-handed B-DNA and
left-handed Z-DNA. The...
Chlamydia is an obligate intracellular bacterial pathogen that causes a variety of disease in animals and humans worldwide. Veterinary chlamydial pathogens can lead to chronic infections and serious consequences that result in millions of dollars of losses in animals and resources in the agricultural industry in countries that rear ruminants....
The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...
Recent state and national standards have increased the interest in engineering at the K-12 level. Science standards, in particular, have begun to make the case for including engineering throughout the K-12 scope of study. Despite the increased attention to engineering, the characteristics and uniqueness of the field of engineering are...
