Scratch test and scanning electrochemical microscopy (SECM) were applied to study the effects of thiosulfate on stress corrosion cracking (SCC) of Alloy 800 in simulated crevice solutions. The results showed that thiosulfate cathodically shifted the pitting potential of Alloy 800 significantly and t
This study investigated the relative and absolute effects of pause-and-talk and response cost on the stuttering rates of four stutterers ages 10 to 17. Ten sessions of pause-and-talk and 10 sessions of response cost presented in a semi random order were provided over a 40-day period within an altern
Association Mapping of Genes Using Whole Genome Polymorphism Arrays: Identification of Markers of Breast Cancer Susceptibility in Alberta Women.
Breast cancer is a heterogeneous, polygenic disease and is influenced by genetic, environmental and life-style factors. Many single nucleotide polymorphisms (SNPs) associated with breast cancer risk have been identified in genome-wide association studies (GWASs) by several research groups for differ
This study describes in detail the processes, interventions, challenges, and selfreported changes associated with implementing the Health-Promoting Schools (HPS) project in Zhejiang Province, China. It is a descriptive study, based on a case study model, using illustrative examples from nine schools
This thesis is designed to identify the major issues involved in the environmental regulation of the oil and gas industry in Nigeria and Alberta. The failure of the regulatory agencies to control environmental degradation experienced in the Nigerian industry is due to existing legislative and admini
In-stent restenosis has always been an important issue to deal with after cardiovascular stent implantation. Various strategies have been proposed to overcome the issue. In our strategy we have combined the drug delivery principle with strategies of tissue engineering to develop the stent scaffold.
Three dimensional dynamic analysis of the human hand for predicting tendon, ligament and nerve wear in the carpal tunnel during typing.
The hand is one of the most complex parts of the human body. The hands contain forty percent of the bones and fifty percent of the muscles in the human body. In addition, the opposable thumb is one of two features that separates primates from other animals.; This study develops a three dimensional,
Tremendous growth in wireless technology comes with added complexity in testing these networks before deploying them for commercial use. For many years, testbeds and simulators were the ideal choices for performance analysis. However due to their limitations with respect to accuracy, complexity and
The relationship between early childhood caries and caregivers' oral health knowledge and behavior among Medicaid-eligible children in North Carolina.
Dental caries is increasing among low-socio economic children. A demonstration project, "Into the Mouths of Babes" (IMB), utilized physicians to prevent dental caries in Medicaid-enrolled children. The purpose of this study is to characterize oral health knowledge and behaviors among caregivers of M
In 3 essays, regime switching and structural break models are explored and used in the fields of International Economics, Health Economics, and Macroeconomics. (1) Characterizing the Real Exchange Rate in a Switching AR(1) and Unit Root Model best represents its behavior in our long horizon data for
This thesis describes 3 thematically linked projects exploring outcomes for hospitalized medical patients. Project 1 examines the accuracy of various models in predicting post-discharge outcomes in patients with heart failure (HF). Project 2 explores the relationship between teaching and non-teachin
The present study explored the cue-reactivity associated with reports of gambling wins. A 61-item questionnaire administered via the Internet collected information on gambling behaviours, effects of reports of large gambling wins, and thoughts that might underlie either the activation or the inhibit
Studies of an end-on inductively coupled plasma atomic emission spectrometer (ICP-AES) and a direct sample insertion inductively coupled plasma atomic emission spectrometer (DSI-ICP-AES).
The studies undertaken in this thesis are the effect of plasma operating parameters on analyte signals in Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) with axial viewing plasma and Direct Sample Insertion Inductively Coupled Plasma Atomic Emission Spectrometry (DSI-ICP-AES), the
Influenza is an enveloped virus, consisting of two surface glycoproteins, neuraminidase and hemagglutinin. The viral receptor is a glycoconjugate on which sialic acid is the terminal sugar. Neuraminidase catalyses the cleavage of the terminal sialic acid from the adjoining carbohydrate moiety, there
A fluorometric enzyme assay was developed to evaluate the ability of a variety of compounds to bind and/or inhibit pyroglutamyl aminopeptidase. Among these compounds were a series of chloromethyl ketone analogs of thyrotropin releasing hormone (TRH) which had been shown to possess TRH-like activity
It is expected by the completion of the Human Genome Project more than 100,000 human disease genes will be discovered, resulting in an increase of genes available for genetic testing. Unfortunately, not enough is known about the meaning of this genetic information and the implications of genetic tes
The objectives of this study were to develop dissolution test methods that can be used to predict the oral absorption of two drug products, etoricoxib (ArcoxiaRTM) and montelukast sodium (SingulairRTM), and to assess the capability of computer simulations using GastroPlus(TM) to establish in vitro/
Using a lens of historical materialism with a Gramscian understanding of hegemony, historic bloc and the state, I argue that President Fernando Henrique Cardoso implemented a model of development under the Washington Consensus that reproduced and accelerated Brazil's situation of dependency. I ask w
Effect of compatibilizer, copolymer and polypropylene type on mechanical properties of polypropylene/recycled EPDM blend.
Incorporation of waste (ethylene propylene diene rubber) EPDM into polyolefins has emerged as a new recycling technique that is eco-friendly and cost effective. The purpose of this study was to recycle EPDM, as well as to develop new impact modified blends. This study, which involved reactive blendi
Internal gravity waves grow in amplitude as they propagate upwards in a non-Boussinesq fluid and weakly nonlinear effects develop due to interactions with an induced horizontal mean flow. In this work, a new derivation for this wave-induced mean flow is presented and nonlinear Schrodinger equations
