Green Salamander Distribution, Abundance, And Physiology In The Southern Blue Ridge, Jillian C. Newman Dec 2017

Green Salamander Distribution, Abundance, And Physiology In The Southern Blue Ridge, Jillian C. Newman

All Theses

Green salamanders, Aneides aeneus, are a priority species throughout their range and have been negatively affected by habitat loss, climate change, disease, and over-collection. Many historical locations for this species in the Blue Ridge Escarpment have not been visited for ~25 years and thus were in need of a status update. I constructed both small-scale and large scale distribution models for green salamanders. For the small-scale distribution model, I conducted visual encounter surveys across three counties in South Carolina using a headlamp to search rock outcrops and binoculars to search trees. I detected green salamanders at 30 of the …

Evaluation Of Shallow Hydraulic Fractures Characterized Using Geophysical Methods, Jessica L.S. Denison Dec 2017

Evaluation Of Shallow Hydraulic Fractures Characterized Using Geophysical Methods, Jessica L.S. Denison

All Theses

Hydraulic fractures are often used to stimulate fluid flow from wells in low permeability geologic units. This capability has been beneficial to the oil and gas industry as well as the remediation industry. The shape and extent of a hydraulic fracture and the distribution of granular proppant affects the performance of a hydraulic fracture during well stimulation. Several methods of tracking the location of hydraulic fractures have been developed (tiltmeter mapping, microseismic detection, and electric potential), but none have the ability to image the distribution of proppants. Electrical resistivity tomography (ERT) has been proposed as a new method to track …

The Human Journey As Work In Progress, Kymberly Day Dec 2017

The Human Journey As Work In Progress, Kymberly Day

All Theses

Sampling gesture, form, and monumentality from Classical figure sculpture, art history becomes an avenue for exploring tropes of the parallels between man and animal. Raw construction and shipping materials comprise these figures, interrupting conventions of display, archive, transport, and institution. Species are spliced and integrated into the human figure in each of the compositions. Traditionally, the animal is used as metaphor for different human conditions, emotions, and behaviors; our relationships to animals is one that stands the test of time in art. The animal becomes an extension of the figure's human-ness, while also acting as mere prop for the figure. …

Effective Parental Cooperation And Communication As Protective Factors For Adult Offspring Of Divorce, Damla Til Ogut Dec 2017

Effective Parental Cooperation And Communication As Protective Factors For Adult Offspring Of Divorce, Damla Til Ogut

Theses and Dissertations

Research and society have focused attention on how divorce affects family dynamics for decades. The clinical literature points to significant discrepancies in psychological variables between offspring from divorced versus intact families, suggesting that divorce contributes to negative psychosocial outcomes. Accordingly, investigations have revealed the adverse effects of co-parental conflict and antagonistic communication on divorce offspring’s psychological outcomes. Although parental cooperation and communication are suggested to serve as protective factors, more research is needed, given the current literature’s reliance on measures of psychopathology, yet making conclusions on psychological wellness. Among 244 college students, results indicated that divorce offspring reported lower levels …

Substance Abuse And Other Factors That Influence Recidivism For Mental Health Court Graduates, Justine Maria Swanson Dec 2017

Substance Abuse And Other Factors That Influence Recidivism For Mental Health Court Graduates, Justine Maria Swanson

Theses and Dissertations

Mental health courts (MHC) were designed to divert the overwhelming number of individuals with mental illness involved in the criminal justice system from incarceration through specialty court proceedings intended to meet their unique needs. Individuals who have both mental health problems and substance use are at a disadvantage. For them, this combination contributes to more severe mental health symptoms, physical health issues, interpersonal challenges, and legal problems. The co-occurrence of mental illness and substance use is increasing in prevalence within both the community and justice system settings; however, few studies have explored the effectiveness of MHCs for this specific population …

Development Of Large-Area Gem Detectors For The Forward Muon Endcap Upgrade Of The Cms Experiment And Search For Sm Higgs Boson Decay In The H → Τ+Τ− → Μ+Μ−¯Νμνμ¯Ντντ Channel At √ S = 13 Tev, Vallary Shashikant Bhopatkar Dec 2017

Development Of Large-Area Gem Detectors For The Forward Muon Endcap Upgrade Of The Cms Experiment And Search For Sm Higgs Boson Decay In The H → Τ+Τ− → Μ+Μ−¯Νμνμ¯Ντντ Channel At √ S = 13 Tev, Vallary Shashikant Bhopatkar

Theses and Dissertations

Gas Electron Multiplier (GEM) technology is being considered for the forward muon upgrade of the Compact Muon Solenoid (CMS) experiment in Phase II of the CERN LHC. The first GEM Endcap (GE1/1) is going to be installed in the 1.5 <| η |< 2.2 region of the muon endcap mainly to control muon level-1 trigger rates after the second long LHC shutdown. A GE1/1 triple-GEM detector is read out by 3,072 radial strips with 453 µrad pitch arranged in eight η-sectors. A meter-long GE1/1 prototype-III was assembled at Florida Tech and tested in 20-120 GeV hadron beams at Fermilab using Ar/CO2 70:30 and the RD51 Scalable Readout System (SRS). Four GEM detectors with 2-D readout and an average measured azimuthal resolution of 36µrad provided precise reference tracks. Construction of this GE1/1 prototype-III detector and its performance in the test beam are described. Strip cluster parameters, detection efficiency, and spatial resolution are studied with position and high voltage scans. The plateau detection efficiency is [97.80 ± 0.2 (stat)]%. The azimuthal resolution is found to be [123.5 ± 1.6 (stat)] µrad when operating in the center of the efficiency plateau and using full pulse height information. The CMS upgrade design calls for readout electronics with binary hit output. When strip clusters are formed correspondingly without charge-weighting and with fixed hit thresholds, a position resolution of [136.8 ± 2.5 stat] µrad is measured, consistent with the expected resolution from strip-pitch/√ 12 = 131.3 µrad. The eight η-sectors of the detector show a similar response and performance. VFAT3 electronics are being considered for the readout system of GE1/1 detectors. The charge that is induced on the GE1/1 readout strips by minimum-ionizing particles is an important parameter that informs the design of the amplifier-shaper input stage of the VFAT3 chip. To estimate the input charge range for these electronics, the most probable value, mean value, and 99th percentile value of the Landau distribution of the charge induced on a single strip are measured and found to be 4 fC, 11 fC, and 115 fC, respectively. The Z/γ∗ → τ τ cross section in proton-proton collisions at √ s = 13 TeV is measured, using data recorded by the CMS experiment at the LHC during 2015 and corresponding to an integrated luminosity of 2.3 fb−1 . The product of the cross section and branching fraction is measured in the dimuon final state to be 1967 ± 121 (stat.) ± 92 (syst.) ± 37 (lumi.) pb, in agreement with the standard model expectation, computed at next-to-next-to-leading order accuracy in perturbative quantum chromodynamics. A search for Standard Model (SM) Higgs bosons decaying into pairs of tau leptons and then to two muons plus (anti)-neutrinos is performed using the data collected by the CMS detector in 2016 with 35.9 fb−1 of integrated luminosity. The upper limits on the cross section relative to SM prediction are calculated in three event categories with different jet multiplicities focusing on Higgs boson signal events produced via gluon-gluon fusion and vector boson fusion. A multivariate analysis with Boosted Decision Trees (BDT) is used to suppress the large Drell-Yan background. The di-tau mass is reconstructed using a Secondary-Vertex fit (SVFit) algorithm using a maximum likelihood approach. Experimental limits are presented in all three categories extracted from the maximum likelihood fit of reconstructed di-tau mass and the visible mass of the dimuon system. The signal strength for the combination of all three categories is estimated as -1.0 ± 1.7. The expected and observed upper limits with 95% CL is at 3.2 and 2.7, respectively, with respect to the SM cross section times branching fraction.

Testing The Wind-Shock Paradigm For B-Type Star X-Ray Production With Θ Carinae, Trisha F. Doyle Dec 2017

Testing The Wind-Shock Paradigm For B-Type Star X-Ray Production With Θ Carinae, Trisha F. Doyle

Theses and Dissertations

We present Chandra X-ray grating spectroscopy of the B0.2V star, θ Carinae. θ Car is in a critical transition region between the latest O-type and earliest B-type stars, where some of these stars are observed to have UV-determined mass-loss rates much lower than theoretically expected. In general, X-ray emission in this low-luminosity regime should be less prominent than in O-star winds, but observations have shown a higher than expected production of X-ray emission from the winds of these stars (e.g., Cohen et al. 2008; Huenemoerder et al. 2012). A hot wind could explain weak UV wind signatures, but this severely …

Surface Modification Of Core-Shell Silver-Titania Nanocomposites With Copper Bipyridine–Phosphonates And Studies On Ag@Tio₂ Mediated Degradation Of Organophosphates, Somayeh Talebzadeh Farooji

Theses and Dissertations

Silver nanoparticles, coated with a titania shell were prepared and were shown to be catalytically active for the rapid degradation of organothiophosphate methyl parathion (MeP). Formation of the degradation product, p-nitrophenolate (PNP) was monitored as a function of pH, using UV-Vis spectroscopy, and 31P NMR spectroscopy confirmed the hydrolysis is the predominant pathway for substrate breakdown under non-photocatalytic degradation. We have demonstrated that the unique combination of TiO2 and silver nanoparticles is required for catalytic hydrolysis with good reproducibility. This work represents the first example of MeP degradation using TiO2 doped with AgNP under mild and ambient conditions. It is …

Gordon

Physics & Astronomy Faculty Publications

Biofilms are communities of microbes embedded in a matrix of extracellular polymeric substances, largely polysaccharides. Multiple types of extracellular polymeric substances can be produced by a single bacterial strain. The distinct polymer components of biofilms are known to provide chemical protection, but little is known about how distinct extracellular polysaccharides may also protect biofilms against mechanical stresses such as shear or phagocytic engulfment. Decades-long infections of Pseudomonas. aeruginosa biofilms in the lungs of cystic fibrosis patients are natural models for studies of biofilm fitness under pressure from antibiotics and the immune system. In cystic fibrosis infections, production of the extracellular …
