Dynamic Optical Model Of The Primate Crystalline Lens And Implications For The Restoration Of Accommodation, David Borja

Open Access Dissertations

The human crystalline lens is a complex, inhomogeneous and dynamic optical element which enables the eye to adjust focus in a process known as accommodation. Age related changes in the optical and mechanical properties of the lens cause a loss in accommodative ability leading to a condition known as presbyopia. Several experimental surgical techniques are under development for the correction of presbyopia. The goal of this dissertation is to better understand the relationship between the crystalline lens shape, its non-uniform refractive index gradient and its optical power and their changes with age and accommodation. In this study direct lens power …

Towards The Total Synthesis Of Thioviridamide: Thiyl Radical Approach To The Beta-Thioenamide Linkage Formation, Jung-Hoon Kang

Theses and Dissertations

We developed an approach to the β-thioenamide linkage contained in the S-(2-aminovinyl)cysteine (avCys) residue of thioviridamide.1,2 Kinetic and thermodynamic control of radical additions of thiols to ynamides were studied for the formation of β-thioenamide linkage. Thiyl radicals are electrophilic and ynamides are electron-rich alkynes. This complementary polarity of the radical and acceptor increases the likelihood of a successful radical addition reaction. Because little is known about these types of compounds (β-thioenamides), we were unsure what kinds of yields and stereoselectivities (cis vs. trans) to expect. The adduct stability is another issue to consider. Fortunately, under typical radical addition conditions, the …

Attitude Estimation And Maneuvering For Autonomous Obstacle Avoidance By Miniature Air Vehicles, James K. Hall

Theses and Dissertations

Utilizing the Euler-Rodrigues symmetric parameters (attitude quaternion) to describe vehicle orientation, we develop a multiplicative, nonlinear (extended) variation of the Kalman filter (MEKF) to fuse data from low-cost sensors. The sensor suite is comprised of gyroscopes, accelerometers, and a GPS receiver. In contrast to the common approach of using the complete vehicle attitude as the quantities to be estimated, our filter states consist of the three components of an attitude error vector. In parallel with the time update of the attitude error estimate, we utilize the gyroscope measurements for the time propagation of the attitude quaternion. The accelerometer and the …

Parentage Statements And Paired Stelae: Signs Of Dynastic Succession For The Classic Maya, Daniel Moroni Stewart

Theses and Dissertations

The purpose of this thesis is to describe and document parentage statements and paired stela found on Maya monuments or portable objects. While the existence of parentage statements, within the Maya text, has been known since the late 1970s, no thesis or major research project has ever been published pertaining to this class of glyphs within the Maya script. In 1977 Christopher Jones is credited with the discovery of parentage statements in Maya hieroglyphic texts (Jones 1977). His discovery was followed by a detailed analysis of parentage statements by Floyd Lounsbury, Peter Mathews, and Linda Schele (1977). They introduced most …

Synthesis And Characterization Of Polymer Brushes For Controlled Adsorption Of Proteins, Olha Hoy

All Dissertations

Performance of biomedical devices to a large extent depends on the interactions between the device surface and the biological liquids/protein molecules. To achieve controllable interactions between the device and biomolecules and still retain the required mechanical strength on the whole, modification of the surface is often done.
In the present study surface properties were modified through a polymer brush approach. After the modification, surfaces gain tunability toward protein adsorption. Mixed polymer brushes consisting of protein repelling and protein attractive components were used, with a 'grafting to' method employed for the synthesis of polymer layers. First, poly(ethylene glycol), the protein repelling …

Ck2 Contributes To The Synergistic Effects Of Bmp7 And Bdnf On Smad 1/5/8 Phosphorylation In Septal Neurons, Florence Chaverneff

Open Access Dissertations

The combination of bone morphogenetic protein 7 (BMP7) and neurotrophins (e.g. brain-derived neurotrophic factor, BDNF) protects septal neurons during hypoglycemic stress. I investigated the signaling mechanisms underlying this synergistic protection. BMP7 (5 nM) increased phosphorylation and nuclear translocation of BMP-responsive Smads 1/5/8 within 30 min in cultures of rat embryonic septal neurons. BDNF (100 ng/ml) enhanced the BMP7-induced increase in phospho-Smad levels in both nucleus and cytoplasm; this effect was more pronounced after a hypoglycemic stress. BDNF increased both Akt and Erk phosphorylation, but pharmacological blockade of these kinase pathways (with wortmannin and U0126, respectively) did not reduce the Smad …

Teacher Efficacy And Its Impact On Student Achievement, Carissa Freeman

Regis University Student Publications (comprehensive collection)

It is apparent that student achievement is of great concern to the stakeholders of the U.S. educational system. School reform not only heavily depends on teachers, but their belief in their own ability to impact student achievement, otherwise known as teacher efficacy. Teacher leaders, administrators, and policy makers have examined various philosophies, methodologies and strategies to support efficacious teachers so that their talent and skills are retained within the classroom, and thereby positively impact student achievement.

Quality In Education: Perspectives Regarding Baldrige-Based Practices And Instructional Leadership In Middle Schools, Felicia Maria Vaughn Coleman

LSU New Orleans Theses and Dissertations

School systems nationwide confront declines in the number of principal applicants while facing increasing student accountability concerns. The idiosyncrasies of adolescent development and the social nature of the educational environment reflect the declines in applicants and impact student accountability. Using a three-tiered case study, the present research inquiry identified perspectives of superintendents, middle school principals, and middle school teachers regarding Baldrige-based practices in the four Malcolm Baldrige National Quality Award-winning school districts in the United States. This study's data illuminated how a non-prescriptive framework such as the Baldrige National Quality Program (BNQP) combined with Baldrige Education Criteria for Performance Excellence …

Spring Break: The Economic, Socio-Cultural And Public Governance Impacts Of College Students On Spring Break Host Locations, John Laurie

LSU New Orleans Theses and Dissertations

Spring Break, which has been transformed from a rather mild mid-winter vacation to a cultural rite over the past seventy-years, allows students to bring their values en masse to the host locations they visit. While only visiting these locales for a short time, college students nonetheless significantly impact the economic, public governance and socio-cultural processes of their Spring Break host locations. This dissertation explores the process of how and why students choose these locations and the impacts that occur as a result. A quantitative approach is used to determine the level of impact on a host location's economic, socio-cultural and …
