Purpose: The initial and long term bond failure rates of two orthodontic indirect bonding methods were compared. Materials and Methods: A review of 191 bondings provided a data base of bond failures for two indirect bonding methods. One method used...
In this work, micro fabrication techniques are explored not only to simplify the production of complex lab on-a-chip devices (LOC), but also micro fabrication will be utilized to create intelligent design features that will enhance an...
Protective coatings; Microelectromechanical systems
PARYLENE (poly-para-xylylene) is mostly used as a conformal protective polymer pin-hole free coating material to uniformly protect any component configuration on diverse substrates. This thesis describes in detail how the unique properties of...
Introduction: Although orthodontics can correct a variety of dental and skeletal
malocclusions, research has shown an increased risk of enamel demineralization leading
to white spot lesions (WSLs). The purpose of this study was to compare the...
This dissertation deals with various imidazole compounds with emphasis on hydrogen bond interactions and weaker intermolecular forces. New amide functionalized polyimidazole metal binding pockets are able to form intramolecular six-membered...
Background and significance: Even with the advent of direct bonding, decalcification remains a problem in orthodontics today. Glass ionomer cements have been used in dentistry for fluoride release for years and may have beneficial use in...
Understanding of the band structure of the new nano materials is essential to have a deeper insight into their optical and electrical properties. Along with the existing techniques used for characterization of nano-materials, it is also important...
For more than a hundred million years, male plethodontid salamanders have
utilized non-volatile, proteinaceous courtship pheromones to regulate female mating
receptivity and promote mating success. These pheromones - which are delivered...
Assessing the functionality of the endothelium can provide insight into the initiation and formation of arterial diseases. One of the most important functions of the endothelial layer is its permeability. The integrity of the cell monolayer and its...
Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in half the time...
This dissertation provides an examination of contributing factors to high quality teacher-student relationships during adolescence. High quality teacher-student relationships have been linked to better academic, emotional, and social functioning...
This dissertation is an investigation of the influence of individual characteristics and school climate on the participation in deviant behaviors. The literature review provides a review of adolescent development and theories that guide the...
In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated
micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have
been recently developed as stylus for Atomic Force Microscopy (AFM). Integration...
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
The study purpose was three-fold: finding a point of entry for primary prevention of child neglect, assessing for child neglect risk level for both first-time mothers and their partners, and individuals opinions about establishing and administering...
This study expands our efforts to make a new class of Pt (II) compounds analogous to cisplatin and its derivatives using sterically hindered ligands. Pt compounds in this series have been synthesized using specially designed pyridine and...
Cardiac mapping has become an important area of research for understanding the mechanisms responsible for cardiac arrhythmias and the associated diseases. Current technologies for measuring electrical potentials on the surface of the heart are...
Chapter I . Seven novel head-to-tail cyclic pentapeptides and pseudopentapeptides containing the arginine-glycine-aspartic acid (RGD) tripeptide motif were synthesized. All of the peptides were constructed using solid phase peptide synthesis....
The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...
Enzymatic hydrolysis is the most common method of producing fermentable sugars from lignocellulosic biomass. Limitations to this step include the high cost of enzymes, and the time required to process the biomass. To increase the throughput and...
