Probing Protein And Organothiol Interactions With Gold Nanoparticles, Karthikeshwar Vangala

Theses and Dissertations

Proteins and organothiols are known for their high binding affinity to noble metal surface including gold nanoparticles (AuNPs). Numerous reports have been dedicated to AuNP interaction with protein or organothiol alone. Competitive protein and organothiol (OT) interaction is, however, mostly an unexplored area. The research reported here focused on developing a fundamental understanding of sequential and simultaneous protein and organothiol interaction with AuNPs in which protein and OT are added either simultaneously or sequentially into the colloidal AuNP solutions. In studies of OT interactions with bovine serum albumin (BSA) stabilized AuNPs, we found that the protein coating layer is highly …

Cryopreservation Of Equine Spermatozoa: Identification Of Good And Poor Freezer Stallions And Effect Of Sperm Density Per Straw, Abed Sharqy Fahad

Theses and Dissertations

This study was carried out primarily to evaluate the cryo-tolerance of equine semen from four stallions through assessing the spermatozoa motion characteristics with Computer-Assisted Sperm Analysis (CASA). Four stallions were collected during the breeding season (summer). For each ejaculate, fresh and cryopreserved samples were taken for sperm motility characteristics evaluation. Data analysis demonstrated that sperm cells of stallions were significantly affected by (P<0.05) cryodamage. Stallion (A) was cryotolerant, and was classified as a good freezer, whereas stallion (D) was not and classified as a poor freezer regardless of the concentration of sperm. In addition, a concentration of 0.4 x 109 sperm cells/ml had higher percentages of rapid sperm and velocity parameters (P<0.05) compared to 0.8 x 109 sperm/ml. Further research is necessary to identify potential biomarkers for good and poor freezer stallions.

Conceptual Change: The Integration Of Geologic Time Into The Teaching Of Evolution, David L. Ramseyer

Theses and Dissertations

This study attempts to discern if geologic time is a threshold concept for student understanding of evolutionary theory. A threshold concept enables the learner to unpack other concepts because of its importance in thought construction. In this study three teachers and ten sections of biology were investigated from the same high school. Each teacher used the same activities, in the same sequence, and with identical evaluation methods. Students in the treatment group covered a unit on geologic time prior to completing course work on evolutionary theory. Student misconceptions in both control and treatment groups were assessed using a composite concept …

Evaluation Of B-Mode And Color Doppler Ultrasound As Alternative Tools For The Study Of Reproduction, Temperament, And Milk Production- Related Variables In The Bovine, Hector Luis Sanchez-Rodriguez

Theses and Dissertations

An adequate vascular perfusion status is essential not only to maintain life, but to ensure the proper physiology of the different systems that form the animal’s body. Due to its role in the transport of oxygen and nutrients toward, and the removal of cellular waste products away from the body’s tissues, the circulatory system is responsible for the maintenance of body homeostasis. Production related functions in farm animals are not an exception, and directly depend on sufficient vascular physiology. In the past, the study of blood flow in large domestic species was restricted to highly invasive techniques. However, even when …

Factors That Influence The Participation Of Immigrant Latino Parents In The Special Education Process Of Their Children With Disabilities, Maria Isolina Ruiz

LSU New Orleans Theses and Dissertations

The Individuals with Disabilities Education Act emphasized the importance of parents’ participation in all educational decisions concerning their children with disabilities. However, parents’ ability to actively participate in, and contribute to, their children’s special education process is influenced by a variety of parent and school related factors. For immigrant Latino parents, these factors may include additional issues related to cultural and linguistic diversity not experienced by most parents. This study examined the experiences of immigrant Latino parents when navigating the special education system as well as the impact that such experiences had on parents’ participation in the special education process …

Conflict Resolution: Cultural Understanding Imperative, Livingston S. Tindal

The Journal of Values-Based Leadership

Business transactions and other potential incidences of conflict resolution must be met by participants who have transcended the isolating and often arrogant traits of individualism and must expand to embrace the collective — to realize the importance of learning and understanding cultural differences and whatever creates the uniqueness of the individual. This is particularly critical for success in the global marketplace.

Values-Based Leadership: A Shift In Attitude, Joseph Hester

The Journal of Values-Based Leadership

To genuinely refer to leadership as “values-based,” a shift in attitude is required and the “ethics of care” must be embraced. This modification will ostensibly involve a subjective commitment to reason consistently and prudently, to care for others, and to dedicate oneself to reconsider his or her actions and behaviors.

Pat Pratt awoke frantic with the thought that it was raining. He was at the window, drawing the curtain, before fully awake. Long shadows of trees and mailboxes cut across the neighborhood lawns. His heart lifted. This was the day he’d been waiting for since he’d become mayor and somehow, in the last few weeks, it had snuck up on him.

A Descriptive Analysis Of The Effects Post Discharge Phone Calls Have On Readmission Rates For Medicare Beneficiaries, Heaven Owens

Regis University Student Publications (comprehensive collection)

One in five Medicare patients is readmitted within 30 days of a previous hospitalization, which impacts patients and the healthcare system with exponential expenditures (Allaudeen, Vidyarthi, Maselli, Auerbach, 2011). The Centers for Medicare and Medicaid Services have mobilized recovery audits to begin recapturing funds related to readmission, and medical institutions must take an active role to ensure their financial integrity and protect their clinical reputation. For the purpose of this project, the population of interest was Medicare beneficiaries age 50 through 88 with a primary diagnosis of Chronic Obstructive Pulmonary Disease (COPD) or Congestive Heart Failure (CHF). The intervention included …

Data Integration: A Case Study In The Financial Services Industry, Louis Epie

Regis University Student Publications (comprehensive collection)

Current economic conditions result in banks participating in multiple mergers and acquisitions. This results in banks inheriting silo and heterogeneous systems. For banks to remain competitive, they must create a strategy to integrate data from these acquired systems in a dynamic, efficient, and consumable manner. This research considers a case study of a large financial services company that has successfully integrated data from different sources. In addition this research investigates endeavors that experts in the field have undertaken to develop architectures that address the problems with data integration and appropriate solutions.

The Effect Of Co-Teaching On Student Achievement In Ninth Grade Physical Science Classrooms, Karen M. Lafever

Dissertations

Co-teaching is a method that is increasing within schools across the US as educators strive to leave no child behind. It is a costly method, having two paid instructors in one classroom, with an average of 24 students shared between them. If it significantly increases the achievement of all students, it is well worth the costs involved. However, few studies have analyzed the effectiveness of this method on student achievement. This research follows the academic accomplishments of students in a ninth grade physical science course. Nine sections of the course “Force and Motion” were taught with a single teacher, and …

Structural Design Of Flexible Etfe Atrium Enclosures Using A Cable-Spring Support System, Ryan Paul Bessey

Theses and Dissertations

This research designed and analyzed an innovative structural support system for ETFE (ethylene tetrafluoroethylene) atrium roofs between buildings. A cable-spring system was conceived, which is much lighter and more flexible than arches, frames, trusses, and beams which usually support ETFE roofs. Flexibility was a desirable property because the displacements may vary significantly among the buildings supporting the ETFE atrium roof during wind and seismic loading. The springs in the cable-spring system allow large differential displacements without exerting large support reactions on the buildings. The flexibility of the cable-spring system was compared to the cable-strut system which is used to support …

Viewpoints: Liberatory Ensemble And Character, Christopher Layton Clark

Theses and Dissertations

This dissertation, submitted in article format, explores how the physical movement theories of Anne Bogart's Viewpoints may lead to a liberatory setting, one which echoes the theories of Paolo Freire, for college theatre students. It examines whether Viewpoints is effective in creating a studio classroom culture and whether the Viewpoints exercises can lead to a heightened clarity in individual performance, with a much more satisfying and involved learning experience for students of the theatrical arts. In addition, this dissertation applies the theory of Mead's symbolic interactionism to the discoveries that students make while using Viewpoints exercises. Research methods include autoethnography, …
