Background: Malocclusion can affect an individual's quality of life. Unfortunately, access to orthodontic treatment is limited for many children. Access is improved when orthodontists select practice locations where their services are most needed....
INTRODUCTION: Attention Deficit/Hyperactivity Disorder (ADHD) is a disorder that is prevalent throughout the world. It is believed that 5% of school aged children suffer from ADHD, with some estimates indicating as high as 10% may suffer from the...
DNA microarrays--Statistical methods; Gene expression--Statistical methods
Data derived from gene expression microarrays are frequently used to identify candidate genes which can characterize and distinguish between two biological phenotypes. A key step in this process is the selection of an appropriate test statistic to...
In this dissertation research, we aim to solve problems of two types of survival data, clustered survival data with potentially informative cluster size and sojourn time data. The methods for these two types of data are different. However, both...
The phase II clinical trial is a critical step in the drug development process. In the oncology setting, phase II studies typically evaluate one primary endpoint, which is efficacy. In practice, a binary measurement representing the response to the...
Three lab concrete mixes and one field concrete mix were evaluated to establish
the Air Void Analyzer (AVA) as a means of real-time, ���In-the-Field��, Quality Control
testing method. In this study, both the Air Void Analyzer and...
Clustered longitudinal data is often collected as repeated measurements on subjects over time arising in the clusters. Examples include longitudinal community intervention studies, or family studies with repeated measures on each member. Meanwhile,...
The performance of pediatric circulatory support devices depends on the properties of pediatric blood. This study reports the measurement of the viscoelastic properties of pediatric blood at 37°C [body temperature]. The results were compared with...
A blinded observational cross-sectional in vitro study was conducted to compare the diagnostic accuracy of observers viewing images made using cone beam computerized tomography (CBCT), panoramic radiography and linear tomography. The sample...
Aims. The primary aim of this randomized, blinded, controlled clinical trial was to compare the percent root coverage obtained using a coronally positioned tunnel surgery plus an acellular dermal matrix allograft (ADM) with single tooth sling...

In order to allow quality healthcare to be available to more people, healthcare must be as affordable as possible. Ideally this will be done through the elimination of the waste that is built into the current healthcare system. One area that is...
The following thesis examines the relationship between site geology and ground motion amplification for medium sized earthquake events in the Ohio Valley area. This thesis also includes a Rapid Screening Guide that can be used to estimate...
The airline regulatory communities are interested in methods that can access degradation in the polymer insulation of aging aircraft wiring. This study investigates the response of bulk polymer films and aircraft wiring under indentation; changes...
The Kosair Children's Hospital, located in Louisville, Kentucky, is the only children's hospital in the state. Recently, the hospital's emergency department has developed concerns with patient satisfaction. Patients have experienced excessive...
Air void structure in hardened concrete is critical to its durability. This project mainly focuses on investigating the air void system in hardened concrete with the microscopic analysis Linear Traverse Method specified by ASTM Specification...
A combination of three techniques – high resolution micro computed tomography (micro CT) scanning, Archimedes-based volume fraction measurement and serial sectioning or milling – were used to determine the volume fraction, trabecular thickness,...
Prostate cancer (PCA) development may be influenced by genetic variations within oxidative stress response (OSR) related mechanisms, such as antioxidation (e.g.,
carcinogen metabolism/detoxification), DNA repair, and apoptotic regulation. Excessive...
Emergency medicine--Diagnosis; Emergency medical services
A retrospective study involving the secondary analysis of public health surveillance records was undertaken to characterize the reliability and validity of an EMS dispatch data-based scheme for assigning emergency patients to surveillance syndromes...
Polymorphisms in the adrenergic receptor beta-2 (ADRB2) gene have been studied in relation to risk of Type 2 diabetes and obesity, but few studies have investigated associations with breast cancer. The purpose of this research was to evaluate the...
Rising concerns about dependency on fossil fuels in the 21st century has sparked a growth in research for renewable energy sources. One renewable energy production process of interest is the reduction of cellulose into fermentable sugars by means...
