Rationale:
The sampling of sequential, annually formed bone growth layers for stable carbon (δ¹³C values) and nitrogen (δ¹⁵N values) isotope analysis (SIA) can provide a time series of foraging ecology data. To date, no standard protocol exists for the pre-SIA treatment of cortical samples taken from fresh, modern, bones.

(2015). Effects of
Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

To assess the conversion and embedment of yttrium nitrate to yttrium oxide using selective laser melting, a thermodynamic approach for laser power and scan speed predictions on surface temperature, recoil pressure, and resulting track morphology window are employed. Inkjet printing is used to deposit the liquid film of yttrium nitrate...
Emerging applications for robotic data collection include ocean monitoring, emergency response and urban search and rescue. At the core of these applications is a robot's ability to make informed decisions on incomplete data. This dissertation addresses this problem by developing novel techniques for modeling and estimating structured environments using deep...
Local property-owning residents maintain high levels of interest
and awareness regarding a neighboring natural resource complex.
Factors, however, such as proximity, personal interests, use patterns
and economic considerations cause local inhabitants to have an
inaccurate perception of the natural resource complex. The nature
of local resident perception can be analyzed...

A THESIS
In this study, we explored the relationships among gender, age, daily stressors, positive and negative affect, and neuroticism on cortisol outcomes in older men and women. We were particularly interested in whether variation in positive affect would have an effect on variation in negative affect and if this relationship would...
