Thiomicrospira Crunogena: A Chemoautotroph With A Carbon Concentrating Mechanism, Kimberly P. Dobrinski Jul 2009

Thiomicrospira Crunogena: A Chemoautotroph With A Carbon Concentrating Mechanism, Kimberly P. Dobrinski

USF Tampa Graduate Theses and Dissertations

Gammaproteobacterium Thiomicrospira crunogena thrives at deep-sea vents despite extreme oscillations in the environmental supply of dissolved inorganic carbon (DIC; =CO2 + HCO3- + CO3-2). Survival in this habitat is likely aided by the presence of a carbon concentrating mechanism (CCM). Though CCMs are well-documented in cyanobacteria, based on this study T. crunogena is the first chemolithoautotroph to have a physiologically characterized CCM. T. crunogena is capable of rapid growth in the presence of 20 micrometers DIC, has the ability to use both extracellular HCO3- and CO2, and generates intracellular DIC concentrations …

Glycosylation Modulates Cardiac Excitability By Altering Voltage-Gated Potassium Currents, Tara A. Schwetz Jul 2009

Glycosylation Modulates Cardiac Excitability By Altering Voltage-Gated Potassium Currents, Tara A. Schwetz

USF Tampa Graduate Theses and Dissertations

Neuronal, cardiac, and skeletal muscle electrical signaling is achieved through the highly regulated activity of several types of voltage-gated ion channels to produce an action potential (AP). Voltage-gated potassium (Kv) channels are responsible for repolarization of the AP. Kv channels are uniquely and heavily glycosylated proteins. Previous reports indicate glycosylation modulates gating of some Kv channel isoforms; often, terminal sialic acid residues alter Kv channel gating. Here, we questioned whether alterations in glycosylation impact Kv channel gating, thus altering APs and cardiac excitability. ST3Gal-IV, a sialyltransferase expressed at uniform levels throughout the heart, adds …

Spoken Word Recognition In Quiet And In Noise By Native And Non-Native Listeners: Effects Of Age Of Immersion And Vocabulary Size, Astrid Zerla Doty Jun 2009

Spoken Word Recognition In Quiet And In Noise By Native And Non-Native Listeners: Effects Of Age Of Immersion And Vocabulary Size, Astrid Zerla Doty

USF Tampa Graduate Theses and Dissertations

In spoken word recognition, high-frequency words with few neighbors and less frequently occurring minimal pair neighbors (lexically easy words) are recognized more accurately than low-frequency words with many and more frequently occurring neighbors (lexically hard words). Bradlow and Pisoni (1999) found a larger easy hard word effect for non-native than native speakers of English. The present study extends this work by specifically comparing word recognition by non-native listeners with either earlier or later ages of immersion in an English-speaking environment to that of native English speakers. Listeners heard six lists of 24 words, each composed of 12 lexically easy and …

The Role Of Interference In Moderating The Relationship Between Working Memory Capacity And Cued-Recall, Umit Akirmak Jun 2009

The Role Of Interference In Moderating The Relationship Between Working Memory Capacity And Cued-Recall, Umit Akirmak

USF Tampa Graduate Theses and Dissertations

Although much research has been done on how well working memory predicts processing of consciously activated information, research on the possible influences of working memory on automatically activated information is scarce (Barrett, Tugade, & Engle, 2004). Working memory capacity (WMC) may be related to how much information is activated automatically by either aiding ease of access to relevant information or by its role in inhibiting irrelevant thoughts and information (i.e., noise). The purpose of the present study was to examine the contribution of individual differences in WMC on implicit and explicit processes in cued recall. Participants studied target words and …

Studying The Effects Of Motivation On The Emergence Of Untrained Verbal Operants, Alysia Gilliam Jun 2009

Studying The Effects Of Motivation On The Emergence Of Untrained Verbal Operants, Alysia Gilliam

USF Tampa Graduate Theses and Dissertations

In Skinner's (1957) analysis of verbal behavior, the tact and mand are suggested to be functionally independent verbal operants. Many studies evaluating the verbal operants have provided results consistent with Skinner's notion of functional independence. For example, previous studies have yielded results showing that responses taught as tacts failed to emerge as mands unless they were directly trained as such. However, in many of the studies evaluating the functional independence of the verbal operants it is unclear whether the mand conditions were designed to actually evaluate that response function. The current study replicated and extended the findings of Wallace, Iwata, …

Thyroid Hormone Regulation Of Cholesterol Metabolism, Lindsey R. Boone Jun 2009

Thyroid Hormone Regulation Of Cholesterol Metabolism, Lindsey R. Boone

USF Tampa Graduate Theses and Dissertations

In this study, we examined the effects of thyroid hormone on regulatory processes of cholesterol metabolism. Specifically, the pathways of cholesterol synthesis and cholesterol efflux were investigated. Hepatic HMG-CoA reductase (HMGR) is the rate-limiting enzyme in cholesterol synthesis. Hypothyroid rats exhibit decreased expression of this gene, which can be induced by subsequent treatment with thyroid hormone. The mechanism of this activation was previously unknown. Utilizing in vivo electroporation, we identified HMGR promoter elements necessary for the induction of HMGR by thyroid hormone. The -316/-321 element, the sterol response element, and nuclear factor-y site were all found to be necessary to …

An Inconsistency-Based Approach For Sensing Assessment In Unknown Environments, Jennifer Diane Gage Jun 2009

An Inconsistency-Based Approach For Sensing Assessment In Unknown Environments, Jennifer Diane Gage

USF Tampa Graduate Theses and Dissertations

While exploring an unknown environment, an intelligent agent has only its sensors to guide its actions. Each sensor's ability to provide accurate information depends on the environment's characteristics. If the agent does not know these characteristics, how can it determine which sensors to rely on? This problem is exacerbated by sensing anomalies: cases where sensor(s) are working but the readings lead to an incorrect interpretation of the environment, e.g. laser sensors cannot detect glass. This work addresses the following research question: Can an inconsistency-based sensing accuracy indicator, which relies solely on fused sensor readings, be used to detect and …

Toward Understanding Low Surface Friction On Quasiperiodic Surfaces, Keith Mclaughlin Jun 2009

Toward Understanding Low Surface Friction On Quasiperiodic Surfaces, Keith Mclaughlin

USF Tampa Graduate Theses and Dissertations

In a 2005 article in Science [45], Park et al. measured in vacuum the friction between a coated atomic-force-microscope tip and the clean two-fold surface of an AlNiCo quasicrystal. Because the two-fold surface is periodic in one direction and aperiodic (with a quasiperiodicity related to the Fibonacci sequence) in the perpendicular direction, frictional anisotropy is not unexpected; however, the magnitude of that anisotropy in the Park experiment, a factor of eight, is unprecedented. By eliminating chemistry as a variable, the experiment also demonstrated that the low friction of quasicrystals must be tied in some way to their quasiperiodicity. Through various …

A Greener Vertical Habitat: Creating A Naturally Cohesive Sense Of Community In A Vertical Multi-Family Housing Structure, Justin Onorati Jun 2009

A Greener Vertical Habitat: Creating A Naturally Cohesive Sense Of Community In A Vertical Multi-Family Housing Structure, Justin Onorati

USF Tampa Graduate Theses and Dissertations

Throughout multiple dense, tropical, urban contexts, high rise residential environments have created a sense of social detachment, where public and private green spaces do not often exist. It is through these varieties of green spaces that social interaction is encouraged, and without these social activities taking place, this vertical community becomes almost a meaningless entity within the urban realm. The issue being addressed within this thesis is the scarcity of public and private green spaces within our high density tropical urban fabrics that help to create a sense of community. The majority of dense urban settings that we inhabit today …
