Dynamic Simulation Of A Solar Powered Hybrid Sulfur Process For Hydrogen Production, Satwick Boddu

Theses and Dissertations

The Hybrid Sulfur process is a thermo-electrochemical cycle used to produce hydrogen from water. The process requires a high temperature energy source for H2SO4 decomposition with temperature reaching 800°C. This step is followed by SO2 - depolarized water electrolysis. Using solar energy as the high temperature energy source allows for efficient environmentally friendly production of hydrogen. This method is an alternative to traditional photovoltaic electrolysis for hydrogen production. Making the process economically competitive is a major challenge. Operating the process with changes in the availability of solar energy also increases process complexity. The dependence of the process on solar energy …

Impacts Of Drainage Systems On Stormwater Hydrology: Rocky Branch Watershed, Columbia, South Carolina, Logan Ress

Theses and Dissertations

The effects of urbanization and associated land use changes, specifically increases in impervious surfaces, have long been the focal point of urban hydrologic research. However, studies and calculations that consider impervious surfaces alone do not encompass all factors that influence urban hydrologic response. Artificial structures such as storm sewer (SS) systems and road networks increase rates of stormwater conveyance, yet these artificial networks are rarely considered in computations of drainage densities and associated hydrologic alterations. This study examines several hydrologically relevant descriptors that can be used to better understand the impact of urbanization on small watersheds. Rainfall and stormflow data …

Individual Differences In Music Discrimination And Their Relation To Reading And Reading-Related Skills In Children, Elaina C. Hill

Theses and Dissertations

Research suggests that there may be a relationship between music and reading. Some researchers have found that musical rhythm is related to reading in children, while others have found that it is musical pitch and not rhythm that correlates with reading. Prosody is the melodic element of language that encompasses both pitch and rhythm. In the past, these have been studied separately. In the present study, we analyzed pitch and rhythm discrimination skills, phonological awareness, prosody and reading in thirty-nine seven and eight year old children. We predicted that music and reading skills would be related, and that prosody would …

A Mixed Method Feasibility Assessment Of A Youth Participatory Action Research Program To Promote Physical Activity: Evaluating Implementation Within Two Pre-Existing Aftercare Programs Serving Middle School Youth, Michelle Abraczinskas

Theses and Dissertations

Obesity interventions to date have had small effects, which may be due to youth disengagement. In youth participatory action research (YPAR), youth become involved in research to make changes that impact their lives. Thus, integrating YPAR into a physical activity intervention, like we do in the current study, is a novel strategy to engage youth and increase empowerment for health behavior change. YPAR is typically implemented with high school youth, standalone, and within elective classrooms or focused after school programs; yet, YPAR can benefit all youth, so we expanded its reach into pre-existing aftercare programs. Participating youth were predominantly minority, …

Reading Material: Personal Libraries And The Cultivation Of Identity In Revolutionary South Carolina, Gabriella Angeloni

Theses and Dissertations

In South Carolina, a colony known for its wealth and transatlantic connections, private libraries offer a unique lens through which to explore the culture of reading and book ownership that was an essential part of daily provincial and early national life. Largely overlooked by historians, personal libraries functioned as statements of wellrounded, often cosmopolitan identities before, during, and after the Revolutionary War. A careful reading of newspaper advertisements, probate inventories, loyalist claims, and correspondence, in conjunction with extant books, bookcases, portraiture, and spaces allows us to reconstruct the culture of reading and book-ownership that dominated Lowcountry society before 1800. Doing …

The Effect Of Mindful Practices On The Independent Learning Process Of Third-Grade Montessori Students, E. Simone Mori

Phenotypic Response Of Marine Cryptophytes To Varying Spectral Irradiance, Kristin M. Heidenreich

Theses and Dissertations

Cryptophytes are eukaryotic algae found in a variety of aquatic ecosystems, that vary in the color of light available for photosynthesis. This algal division displays a diversity in necessary photosynthetic pigments, possessing either phycoerythrin (Cr-PE; “pink”) phycocyanin (Cr-PC; “green”). According to the theory of complementary chromatic adaptation, this diversity should help maximize absorption of light within natural environments. The objective of this study was to determine if pigmentation related to growth performance in environments of differing spectral irradiance. Eight species of marine cryptophytes (5 Cr-PE and 3 Cr-PC species) were grown under four different spectral light environments. Growth rates, cellular …

Progress Monitoring Timing Effects In Speech And Written Language Therapy, James P. Blaida

Theses and Dissertations

Progress monitoring is a crucial aspect of speech-language pathology. Without it, speech-language pathologists (SLPs) have little way of determining if patients are making progress with the implemented therapy. Currently, most SLPs perform progress monitoring during therapy. This study compared the traditional, status-quo, method of progress monitoring to that of progress monitoring performed before therapy begins in an effort to determine if a timing change would affect therapy outcomes. 2 boys, receiving articulation therapy, and 1 girl, receiving spelling therapy, each had 1 treatment goal for the during condition and 1 treatment goal for the before condition. The children all received …

Fandom In Politics: Scale Development And Validation, Won-Ki Moon

Theses and Dissertations

Despite the importance of fandom in politics to understanding individuals’ political behaviors, reliable scales measuring political fandom are lacking. To fill this gap, the present study constructs and validates a new scale for political fandom. First, by reforming existed questions and making new questions, the author derived 42 questions belonging to seven dimensions as an initial item pool based on conceptualization. Second, to refine and develop the scale, the researcher conducted exploratory factor analysis and confirmatory factor analysis. According to the result of the studies, the final factor model of political fandom retained 25 questions and seven dimensions. In addition, …

Beyond Preservation: Reconstructing Sites Of Slavery, Reconstruction, And Segregation, Charlotte Adams

Theses and Dissertations

The Secretary of the Interior’s Standards for the Treatment of Historic Properties define reconstruction as “the act or process of depicting, by means of new construction, the form, features, and detailing of a non-surviving site, landscape, building, structure, or object for the purpose of replicating its appearance at a specific period of time and in its historic location.”1 Reconstruction is a controversial treatment method among historic preservationists, so this thesis seeks to answer the question of why stewards of historic sites still choose to reconstruct nonextant buildings. It explores three case studies: (1) the slave buildings of Mulberry Row at …

Understanding The Adsorption And Nucleation Of Transition Metals On A Model Carbon Support, Grant S. Seuser

Theses and Dissertations

Heterogeneous catalysis plays a vital role in the commercial production of chemicals. However, much is still unknown about the fundamental surface chemistry involved in catalyst preparation and the surface chemistry of the catalysts themselves. In the first part of this work, a surface science approach was employed to develop a fundamental understanding of the surface chemistry of strong electrostatic adsorption (SEA) of metal precursors on a model carbon support, highly oriented pyrolytic graphite (HOPG). SEA is a wet impregnation method in which anionic/cationic metal precursors are adsorbed onto positively/negatively charged functional groups by adjusting the pH of the solution above …

State Specific Poverty Thresholds Adjusted For Cost Of Living Differences, Melissa Gentry

Theses and Dissertations

While poverty is undoubtedly one of the most widely used domestic indicators of social wellbeing, its measurement has a critical shortcoming. Using national poverty thresholds ignores the potential differences in the cost of living across states. States use the national poverty threshold when conducting poverty research and assessing community demographics. Theoretically price level differences between states could mean that, if poverty thresholds were adjusted for cost-of-living by state, the adjusted poverty rate could be different than the official poverty rate Using data specific to individual states that can be found in the Census Bureau’s American Community Survey, geographically specific thresholds …

Assessment Of An Educational Intervention To Increase Knowledge And Intention To Take Hpv Vaccine And Cervical Cancer Screening In Nigeria, Chigozie Anastacia Nkwonta

Theses and Dissertations

Nigeria has some of the highest rates of cervical cancer morbidity and mortality in sub-Saharan Africa. Both the human papillomavirus vaccine (HPV) and cervical screening are effective prevention strategies against both HPV infection and cervical cancer. Lack of awareness, limited knowledge, limited decision-making agency, lack of spousal support and stigma are barriers to uptake of these preventive measures. Given patriarchal structures and norms through which men control family resources and dominate decisions, male involvement in initiatives aimed at improving sexual and reproductive health is necessary. Community-based health education is an effective intervention to improve knowledge and reduce stigma. The aim …

Neuroanatomical Correlates Of Speech And Melody Repetition In Chronic Stroke, Sarah Elizabeth Bradford

Theses and Dissertations

The ability to repeat speech is impaired in most individuals with aphasia. Recent evidence suggests damage to area Spt (boundary of the parietal and temporal lobes at the Sylvian fissure) may cause the repetition difficulties commonly seen in aphasia. This study examined if such repetition impairments are specific to speech or reflect a more general repetition deficit, and determined how regional and network brain damage predict repetition impairments. Participants in the chronic phase of stroke (N=47) listened to a series of ten five-second melodies that consisted of six tones and repeated the melody (by humming) following its presentation. The participants’ …

Visions For The Viewer: The Influence Of Two Unique Easel Paintings On The Late Murals Of Pierre Puvis De Chavannes, Geoffrey Neil David Thomas

Theses and Dissertations

While certainly not lost to the history of art, Pierre Puvis de Chavannes has never enjoyed the status of the titans of the modern canon who openly expressed their indebtedness to him. Georges Seurat, Vincent van Gogh, Pablo Picasso, and so many other artists known to the general public the world over paid tribute to the artist once dubbed “The Painter of France” at a banquet held in his honor to coincide with a retrospective exhibition on the occasion of his seventieth birthday.

Interestingly enough, defenders of the old, academic guard, such as William-Adolphe Bouguereau, Alexandre Cabanel, and Jean-Léon Gérôme …

The Popular Education Question In Antebellum South Carolina, 1800-1860, Brian A. Robinson

Theses and Dissertations

This dissertation reviews the struggle for popular education in Antebellum South Carolina. It contends that the failure of popular education in South Carolina was not a foregone conclusion nor was it mistake by school administration or state leaders, but instead, the failure to provide education for the white majority was the result of an intended goal. This project concludes that South Carolina remained without a system of public schools for the majority of citizens because those who opposed general education firmly believed popular education held the seeds of revolution while ignorance the better tool to perpetuate the status quo.
