Field And Laboratory Testing Of Approaches To Smart Whole-House Mechanical Ventilation Control, Florida Solar Energy Center, Eric Martin

FSEC Energy Research Center®

Whole-house mechanical ventilation is a critical component to a comprehensive strategy for good indoor air quality (IAQ). However, due to lack of integration with standard heating and cooling systems, and perceptions from a portion of the homebuilding industry about risks related to increased energy use, increased cost, and decreased comfort, voluntary and code-required adoption varies amongst regions. Smart ventilation controls (SVC) balance energy consumption, comfort, and IAQ by optimizing mechanical ventilation operation to reduce the heating and/or cooling loads, improve management of indoor moisture, and maintain IAQ equivalence according to ASHRAE 62.2.Suggested Citation:Martin, E.; Fernaughty, K.; Parker, D.; Lubliner, M.; …

Interplay Of Molecular And Nanoscale Behaviors In Biological Soft Matter, Nicholas Ciaffone

Electronic Theses and Dissertations

The complexity of biological soft matter at the sub-micrometer level is fundamentally correlated to the functionalities at the larger scale. Reflecting the level of heterogeneities in the properties of systems remains challenging when probing small scales, due to the mismatch between the area surveyed with the tools offering nanoscale resolution, such as atomic force microscopy (AFM), and the scale of natural variations inherent to biology. Hence, to understand the physiological and mechanical alterations that occur within a single cell relative to a cell population, a multiscale approach is necessary. In this work we show that it is possible to observe …

The Influence Of Family Communication Styles On Campus Experience In College-Aged Children, Madison Kjosa

Honors Undergraduate Theses

As an environment, the modern university setting is diverse and subject students to numerous challenges and opportunities that prepare them to enter careers, build families, and grow as an individual. Yet what a student experiences in college differs greatly and is shaped by internal and external factors in their environment, including campus participation, college self-efficacy, depression and stress. Prior research indicates the impact of family on how a student expresses each of these variables (Schmidtgall, King, Zarski & Cooper, 2000; Bradbury & Mather, 2009; Hannum & Dvorak, 2004; Kenny & Donaldson, 1991; Lopez et al, 2001; Shaver & Mikulincer, 2006). …

Systematic Review And Meta-Analysis: Tuberculosis, Tnfα Inhibitors, And Crohn's Disease, Brent L. Cao

Honors Undergraduate Theses

Inflammation is often a protective reaction against harmful foreign agents. However, in many disease conditions, the mechanisms behind the inflammatory response are poorly understood. Often times, the inflammation causes adverse effects, such as joint pain, abdominal pain, fever, fatigue, and loss of appetite. Thus, many treatments aim to inhibit the inflammatory response in order to control adverse symptoms. Such treatments include TNFα inhibitors. However, a major risk associated with drugs inhibiting tumor necrosis factor alpha (TNFα) is serious infection, including tuberculosis (TB).

Anti-TNFα therapy is used to treat patients with Crohn’s disease, for which the risk of tuberculosis may be …

Development Of Methods To Modulate Natural Killer Cells, Kari A. Shaver

Honors Undergraduate Theses

Natural Killer (NK) cell based immunotherapies have demonstrated success against malignancies and hematological cancers. However, tumors have developed mechanisms to evade detection by and suppress the immune system, commonly through altering the expression of cell-surface proteins. Overexpression of human leukocyte antigen-E (HLA-E), which binds to the inhibitory NKG2A on NK cells, protects malignant cells from lysis. Downregulating the NKG2A receptor on NK cells should release NK cell inhibition, but proves challenging as NK cells are difficult to transfect and no good methods currently exist. This project is designed to investigate the use of exosomes – small vesicles and natural carriers …

Targeted Delivery Of A Therapeutic Protein For The Treatment Of Alzheimer's Disease, Heather Holman

Honors Undergraduate Theses

Neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease are linked to mitochondrial dysfunction and the underexpression of TOM40, a protein with chaperone-like qualities that is responsible for transporting precursor proteins into the mitochondria. Overexpression of TOM40 is reported to partially restore mitochondrial dysfunction and decrease the accumulation of neurotoxic aggregates of α-synuclein. Our goal is to develop an effective method for delivery of TOM40 protein to the brain.

Previous studies have used lentiviruses to carry TOM40 into the hippocampus of α-synuclein transgenic mice. The disadvantage of lentiviral transfection is the random insertions of the target gene into the host …

This survey included a 12 item “Domino scale” on student nursing opinions …

Potential Relationship Between Vascular Depression And Autobiographical Memory Specificity In An Older Adult Population According To The Car-Fa-X Model, Manuel Herrera Legon

Electronic Theses and Dissertations

Vascular depression is a type of depression that has its onset later in life, and it has been associated with cardiovascular or metabolic diseases. Depression can be costly and associated with other health problems, which is why it becomes imperative to uncover the multiple mechanisms of action for depression symptomatology. A proposed mechanism of action for the emergence of depressive symptomatology is poor autobiographical memory specificity according to the CaR-FA-X model. However, it remains unclear whether this mechanism contributes somehow to the vascular depression specific type. The purpose of this research was to determine the potential relationship between the mechanisms …

Openness To Experience: A Predictor Of Technology Use At Any Age?, Olivia Ojalvo

Honors Undergraduate Theses

Technology is an integral part of both modern culture and day-to-day communication. Older adults' relationships with technology are completely different than younger adults' because of the way they have learned to incorporate it into their lives. Past research has shown that certain personality traits can predict technology use in younger adults. The current research hopes to take that finding and see if it applies to older adults, too. Four hypotheses were generated. Participants took a survey that consisted of five different scales and measures. Participants also were asked to answer demographic questions. Independent-sample t-tests and bivariate correlations were run on …

The Effects Of Site-Directed Mutagenesis On Hemerythrin-Like Protein Rv2633c, Kelly M. Rosch

Honors Undergraduate Theses

Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis, one of the top ten causes of death worldwide. One of the genes upregulated in Mtb during macrophage infection is rv2633c, but the structure and function of its gene product remain unknown. Preliminary research has indicated that Rv2633c is a hemerythrin-like protein that exhibits catalase activity and binds two iron atoms using an HHE domain. Additionally, Rv2633c appears to exist as a dimer. The purpose of this project is to identify specific residues outside of the HHE domain that contribute to the protein's iron-binding ability and/or catalase activity, …
