A body composition model to estimate mammalian energy stores and metabolic rates from body mass and body length, with application to polar bears

Derocher, Andrew E., Klanjscek, Tin, Molnár, Péter K., Lewis, Mark A., Obbard, Martyn E.
Many species experience large fluctuations in food availability and depend on energy from fat and protein stores for survival, reproduction and growth. Body condition and, more specifically, energy stores thus constitute key variables in the life history of many species. Several indices exist to...

Astronomy was a culturally prominent practice during the nineteenth century in Britain. In this thesis I examine the development of astronomy in one area, Wales. Astronomy became an important subject in the lecturing industry that emerged during the century as lecturers promoted astronomical...

Neutron stars provide the key to understanding the equation of state at the highest pressure and density. Constraining the mass-radius relation of neu- tron stars will provide opportunities to test the currently conflicting candidates for the equation of state. Next generation instruments, such...

Neutron stars (NSs) are some of the densest objects in the universe. In this thesis, I focus on studying X-ray thermal emission from neutron stars, using X-ray observations of different varieties of NSs. X-ray observations can put constraints on the mass and radius of NSs, and thus on density and...

Connecting galactic to local scales in the neutral interstellar medium across the Local Group
DownloadFall 2020
Star formation drives secular galaxy evolution by linking stars and gas in galaxies. This link forms part of the "baryonic cycle," where stars form from interstellar gas, and a portion of that gas is returned to the interstellar medium upon the star’s death. Understanding the baryonic cycle and...

Density, Microstructure, and Strain‑Rate Effects on the Compressive Response of Polyurethane Foams
Download2021-11-09
Bhagavathula, Kapil Bharadwaj, Meredith, Christopher S., Ouellet, Simon, Satapathy, Sikhanda S., Romanyk, Dan L., Hogan, James D.
Background A better understanding of the efect of density, microstructure, and strain rate on the mechanical response of polymeric foam materials is needed to improve their performance. Objective The objective of this paper is to study the combined infuence of density, microstructure, and...

Microstructure evolution and infrared thermography applied to tensile failure of a dilatant polymeric foam
Download2021-11-01
Bhagavathula, K.B., Parcon, J.S., Azar, A., Ouellet, S., Satapathy, S., Dennison, C.R., Hogan, James D.
In this work, the authors study the thermo-mechanical response of a dilatant polymeric foam in quasistatic tension and compression, focusing on the links between microstructure, mechanical response, and associated temperature rises in these materials. The authors study these links for a...

Muscle Abnormalities in cancer patients: Exploring the biological characteristics of skeletal muscle of cancer patients
DownloadFall 2019
Computed tomography-derived muscle measures of sarcopenia and low muscle radiodensity have been associated with poor outcomes in cancer patients, however, the biological characteristics of the muscle in this population are not well understood. This research was conducted to first evaluate muscle...
