The Kepler Light Curve Of V344 Lyrae: Constraining The Thermal-Viscous Limit Cycle Instability, John K. Cannizzo, Martin D. Still, Steve B. Howell, Matt A. Wood, Alan P. Smale

Aerospace, Physics, and Space Science Faculty Publications

We present time-dependent modeling based on the accretion disk limit cycle model for a 270 d light curve of the short-period SU UMa-type dwarf nova V344 Lyr taken by Kepler. The unprecedented precision and cadence (1 minute) far surpass that generally available for long-term light curves. The data encompass two superoutbursts and 17 normal (i.e., short) outbursts. The main decay of the superoutbursts is nearly perfectly exponential, decaying at a rate ~12 d mag−1, while the much more rapid decays of the normal outbursts exhibit a faster-than-exponential shape. Our modeling using the basic accretion disk limit cycle can produce the …

Pitch Aangle Scattering In The Outer Heliosheath And Formation Of The Interstellar Boundary Explorer Ribbon, Konstantin V. Gamayunov, Ming Zhang, Hamid K. Rassoul

Aerospace, Physics, and Space Science Faculty Publications

The dominant and unexpected feature in the first Interstellar Boundary EXplorer (IBEX) maps is a ribbon of the enhanced energetic neutral atom (ENA) emissions. Presenting the first results from IBEX,McComas et al. identified six possible mechanisms of ribbon formation. One of the mechanisms, the so-called secondary ENA mechanism, was already quantitatively elaborated by Heerikhuisen et al., and they successfully reproduced the main features of the ribbon. We further study the "secondary ENA" mechanism by quantifying a previously omitted stage of the proton evolution between two consecutive acts of the charge-exchange in the outer heliosheath (OHS). The main findings can be …

Low Endemism, Continued Deep-Shallow Interchanges, And Evidence For Cosmopolitan Distributions In Free-Living Marine Nematodes (Order Enoplida), Holly M. Bik, W. Kelley Thomas, David H. Lunt, P. John D. Lambshead

Hubbard Center for Genome Studies (HCGS)

Background: Nematodes represent the most abundant benthic metazoa in one of the largest habitats on earth, the deep sea. Characterizing major patterns of biodiversity within this dominant group is a critical step towards understanding evolutionary patterns across this vast ecosystem. The present study has aimed to place deep-sea nematode species into a phylogenetic framework, investigate relationships between shallow water and deep-sea taxa, and elucidate phylogeographic patterns amongst the deep-sea fauna. Results: Molecular data (18 S and 28 S rRNA) confirms a high diversity amongst deep-sea Enoplids. There is no evidence for endemic deep-sea lineages in Maximum Likelihood or Bayesian phylogenies, …

The Role Of Quality Labels In Farming Diversification And Rural Development, Eman Vella

Masters Theses, 2010-2019

The European Union promotes marketing of quality food products through a quality labelling scheme having three labels known as PDO, PGI and TSG. Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) are two labels that protect products with an association to a particular region. Such products need to have a traditional link with the area as well as unique attributes (known as specifications) that make the product different from the customary. PDO labels designate a product that is linked with an area in every aspect, while PGI labels indicate that the product has a unique geographical link in …

Sustainable Agricultural Management And Landscaping Through Agroforestry And Permaculture Case Study: Northern Malta, Shawn Sammy Vella

Masters Theses, 2010-2019

The farming industry in Malta is facing severe challenges. Many small patches of arable land are being abandoned following land use conflicts and competition from foreign agricultural products. This reduces the economic capacity of the farming industry which leads to soil erosion and land degradation. On the other hand, the remaining land is being intensively farmed with the use of chemical fertilisers and pesticides. Local government following EU regulations is trying to change this trend by aiming more at promoting a sustainable future for this industry in Malta whilst preserving the natural environments, but still many farmers choose not to …

Modulation Of Alpha-Subunit Visit-Dg Sequence Residues Ser-347, Gly-351 And Thr-349 In The Catalytic Sites Of Escherichia Coli Atp Synthase., Laura Elaine Brudecki

Electronic Theses and Dissertations

Binding of inorganic phosphate (P_i) in ATP synthase catalytic sites is a crucial step for the synthesis of adenosine-5'-triphosphate (ATP). ATP is the fundamental means of cellular energy in almost every organism, and in order to gain insight into the regulation of ATP catalysis, critical amino acid residues responsible for binding P_i must be identified. Here, we investigate the role of highly conserved α-subunit VISIT-DG sequence residues αSer-347, αGly-351, and αThr-349 in P_i binding. Mutations αS347A/Q, αG351Q, αT349A/D/R, βR182A, and αT349R/βR182A were generated via site directed mutagenesis. Results from biochemical assays showed that αSer-347 is required …

Transport Of Nordic Seas Overflow Water Into And Within The Irminger Sea: An Eddy-Resolving Simulation And Observations, Xiaobiao Xu, W.J. Schmitz Jr., Harley E. Hulbert, Patrick J. Hogan, Eric P. Chassignet, H.M. Van Aken

Faculty Publications

Results from a climatologically forced, eddy-resolving (1/12 degrees) Atlantic simulation using the Hybrid Coordinate Ocean Model help clarify some presently unresolved connections between volume transports of Nordic Seas overflow water at key locations in the northernmost North Atlantic Ocean. The model results demonstrate that, in addition to the known westward flow through the Charlie Gibbs Fracture Zone (CGFZ), some Iceland Scotland overflow water (ISOW) flows westward through gaps in the Reykjanes Ridge north of the CGFZ into the Irminger Sea, and some flows southward along the eastern flank of the Mid-Atlantic Ridge into the West European Basin. These results provide …

An Exploration Into How Physical Activity Data-Recording Devices Could Be Used In Computer-Supported Data Investigations, Victor R. Lee, Maneksha Dumont

Instructional Technology and Learning Sciences Faculty Publications

There is a great potential opportunity to use portable physical activity monitoring devices as data collection tools for educational purposes. Using one such device, we designed and implemented a weeklong workshop with high school students to test the utility of such technology. During that intervention, students performed data investigations of physical activity that culminated in the design and implementation of their own studies. In this paper, we explore some of the mathematical thinking that took place through a series of vignettes of a pair of students engaged in analyzing some of their own activity data. A personal connection to the …

Green Buildings: A Maltese Perspective, Kevin Muscat

Masters Theses, 2010-2019

As construction and building development increases in the local scene, and the threat of climate change escalates, addressing green buildings on the national agenda is of vital importance. The building sector has a significant potential to implement positive change and hence become more efficient in terms of resource use. The term ‘green’ has been widely used throughout the last few decades to denote environmentally friendly policies, principles and measures. The ever growing popularity of the term was brought about by increasing concerns and issues such as those pertaining to climate change, energy crisis and resource depletion. Central to this debate …

Examination Of The Death Penalty: Public Opinion Of A Northeast Tennessee University Student Sample., Kyle Aaron Burgason

Electronic Theses and Dissertations

How society views the use of the death penalty as a means of punishment greatly affects the decisions of lawmakers, politicians who use it as a platform for election, and the criminals who commit the crime of murder. This study used 40 different vignettes involving real-life murder scenarios in order for participants to form a more precise opinion of what the correct punishment for the crime should be. Given a choice between the death penalty, life without the possibility of parole, a prison term of their choosing, or other, participants were asked to assign a sanction for each vignette. Respondents …

Molecular Evidence Suggests Multiple Evolutionary Origins Of Sociality In The Polyphenic Spider Anelosimus Studiosus (Araneae: Theridiidae)., Nathaniel O. Weber

Electronic Theses and Dissertations

Anelosimus studiosus exhibits two behavioral phenotypes: subsocial and social. This is the only documented spider inhabiting a temperate climate exhibiting social behavior. While the subsocial phenotype is most common throughout the range, the social behavior occurs in isolated pockets in northern latitudes. This study examines the origins of the social phenotype within a segment of the spider's range. Two hypotheses are tested: 1) pockets of social behavior represent a single origin or 2) pockets of social behavior represent local evolutions, thus leading to multiple origins of evolution. Microsatellite loci were used to determine genetic structure of the population and to …

Wrongful Convictions As A Result Of Public Defender Representation., Annie Elizabeth Ross

Electronic Theses and Dissertations

Our criminal justice system works very hard to prevent criminals from harming other individuals; however, unfortunately mistakes happen. One wrongful conviction is one too many. There are multiple factors that can be assumed to be the cause of wrongful convictions. However, due to the lack of directly related research, the determents are not well established. The following research addresses wrongful convictions as a result of public defender representation. Through the process of theory construction, the research uses critical race theory and social disorganization theory to show the relationship between court appointed representation and wrongful convictions. A new theory is also …

Mosaic Analysis With Double Markers (Madm) As A Method To Map Cell Fates In Adult Mouse Taste Buds., Preston D. Moore

Electronic Theses and Dissertations

Taste buds are chemosensory endorgans embedded in the oral epithelium composed of cells that undergo continuous replacement. Mature taste cells live on average 10-14 days and are replaced by new cells when they die. However, the mechanism by which taste cells are produced and integrated into the taste bud as mature taste cells remains unknown. Previous studies approached this issue from either cell cycle gene expression properties or lineage tracing of precursor cells. In our study, we apply a new fate mapping technique that combines these two ideas. This technique, Mosaic Analysis with Double Markers, allows for simultaneous gene knockout …
