Japanese Encephalitis (JE) is a mosquito-borne viral disease responsible for 30,000 to 50,000 reported cases and up to 15,000 reported deaths every year. The disease is a significant public health concern in Bangladesh, but there is no regular surveillance or immunization for JE…

Retaining walls are earth retention structures that are essential in the majority of the construction projects for the overall project's engineering performance, as well as its budget and schedule. These elements constitute a key role in urban development, industrial facilities …
Stress corrosion cracking (SCC) is a major degradation mechanism of Alloy 600 steam generator (SG) tubes composed of three main stages: crack incubation, crack initiation and crack propagation. Since SG tubes act as a barrier between the radioactive material and the atmosphere, …
Arid and semi-arid countries are facing the exhaustion of their water resources and are being forced to use saline water (brackish groundwater and drainage water) for irrigated agriculture. The result is often disastrous as extensive productive regions become salinized. Neverthe…
An area of Shetland is examined in order to identify how Iron Age settlements might have related to each other. The study area contains two brochs. An inter-disciplinary approach is used to identify evidence for other Iron Age settlements and the information is presented as a mo…
Alteration in the tone of pulmonary arteries may lead to disease such as pulmonary hypertension often associated with major cardiac complications. This dysfunction is partly in the pulmonary arterial smooth muscle cells (PASMCs) where the excitation-contraction coupling is modif…
A series of studies were conducted with the aim of showing that the Representational Redescription (RR) model (Karmiloff-Smith, 1992) can be used a general model of cognitive development. In this thesis, 3 aspects of the RR model were explored. The first set of experiments invol…
A computer simulation model of the table contact phase of gymnastics vaulting was developed to gain an understanding of the mechanics of this phase of the vault. The model incorporated a gymnast and a vaulting table, and used a novel two-state contact phase representation to sim…
Mega construction projects are complex undertakings. The complexity is increased during a construction boom in a city such as Dubai where more than 80% of material and labour resources are imported. The complexities inherent in mega construction projects include uncertainty and …
Comparatively little is known about the ability of commercially raised poultry and gamebirds to metabolize therapeutic drugs. The goal of this research was to use a combination of in vitro, in vivo and physiologically-based pharmacokinetic (PBPK) studies to characterize metaboli…
I use GPS velocity field and published geologic slip rates to constrain an elastic block model for Anatolia and surrounding regions. The elastic block model allows us to define plate motion and both strike and tensile slip rates along the major faults. Previous studies (eg., McC…
Scientists face an unprecedented challenge of increasing food production by 100% within the next fifty years to meet demand while responding to the undetermined effect and impact of climate change. To respond to these challenges, scientists are turning to models to assist them i…
Research on the success of women’s entrepreneurship in developing nations is limited. The paucity of information is particularly pronounced in studies related to women-led ventures in conflict and post-conflict economies. Moreover, very little is known about entrepreneurship “be…
Bu çalışmada lise öğrencilerinin matematiksel modelleme becerilerinin incelenmesi amaçlanmaktadır. Araştırmada aşağıdaki sorulara cevap aranmıştır: • Lise öğrencilerinin mantık konusundaki matematik başarısı hangi düzeydedir? • Lise öğrencilerinin matematiksel modelleme becerile…
In this document a highly detailed stochastic soot model limited to 0D simulations is coupled to 3D domains through the use of a Lagrangian parcel-Eulerian fluid method. Although both the stochastic soot model used and the Lagrangian parcel-Eulerian fluid method have long histor…
Complex ecological processes determine whether and how fish species survive in the ocean. For some fishes such as Pacific salmon (Oncorhynchus spp.), these processes are thoroughly studied and modeled. For eulachon (Thaleichthys pacificus), however, these processes are more myst…
Submarine groundwater discharge (SGD) at a continental scale is one of the least constrained components of the hydrologic cycle and may represent a significant flux of iron and silica waters to the global ocean. Quantifying SGD along the Antarctic margin is complicated by comple…
Presented in this dissertation are novel models and techniques to analyze the whirling vibration of drillstrings during oil and gas (O&G) operations. Mathematical models are developed to solve for the dynamic whirl response. For this purpose, the drillstring is modeled by a syst…
The project director created a model for the Baptist State Convention of North Carolina to help pastors lead their churches into a disciple-making strategy of ministry. In chapter 1, the project director provided a description of his ministry context, the rationale for the proje…
