Microhotplates for metal oxide gas sensors are fabricated using platinum microheaters and tested. Power consumption is monitored and temperature distributions are observed using infrared microscopy. Temperature line traces are extracted from the...
Coronary heart disease--Treatment--Cost effectiveness; Angioplasty; Medical laws and legislation--Kentucky
A myocardial infarction (MI) occurs when blood supply to the heart is cut off by a blockage in one of the coronary arteries. Most hospitals treat a patient with thrombolysis or a percutaneous coronary intervention (PC I). The latter has been...
An investigation was made into the relative costs of excavation retention by two systems: conventional soldier pile-wale-tieback support, and support by soil nailing. The investigation included design of excavation supports by the two...
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...
Anxiety in adolescence; Parent and teenager; Parenting
This dissertation examined the prediction of anxiety symptoms over time during
developmentally significant periods - the transition to middle school (12 years old) and
the transition to high school (15 years old). Specifically, relationships...
Determining the etiology of skeletal malocclusion is an important diagnostic step in treatment planning patients with maxillofacial anomalies. Aims: To describe cranial base morphology using cone beam computed tomography (CBCT) images and correlate...
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
Heat pipes; Solar heating--Passive systems; Solar heating--Research; Solar energy--Research
The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
Channel modification has played a vital part in shaping the rivers and streams as
they are seen today. Channel modifications range from the construction of dams and levees
for flood control purposes to channelization of an existing meandering...
Conducting polymers; Polymers in medicine; Myocardium
Hydrophilic and conductive characteristics in polymers are mutually exclusive of each other. Hydrophilic polymer properties allow absorption of water up to several magnitudes above their dry weight. However, due to their molecular structure, they...
Materials management--United States--Data processing; Production control--Data processing; Inventory control--Data processing
Material Requirements Planning (MRP) is one of the earliest production scheduling approaches that utilizes computers. MRP is still regarded as one of the most widely used systems for production scheduling. Even though MRP has made contributions,...
Narrative causal understanding is related to a variety of school-related skills such as reading comprehension, and memory. Previous research shows a developmental trend in the ability to use and understand causal connections that begins at age 4...
Optimizing queries in a distributed database is quite difficult. This work proposes defining new generalized quantifiers which operate on sets rather than tuples. These quantifiers would allow for easier optimization in a horizontally distributed...
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...
Modular hip implants are currently being used in total hip arthroplasty revision procedures because it is common to have little or no bone left in the proximal region of the femur and it is difficult to accurately size implants based off of...
This thesis reports the reactivity of the trithiolato Ru complex PPN[Ru(DPPBT)3] (DPPBT = 2-diphenylphosphinobenzenethiolate) (1a) with alkenes upon oxidation. Complex 1a in acetonitrile shows two redox events at -345 mV and +455 mV in the square...
A potential source of fine grained suspended sediments in a stream system is the
upper hillslopes of the drainage. Quantifying the sediment produced and transported to a
stream from these hillslopes is challenging because of the complex nature of...
Introduction: Autism is a complex developmental disability that typically appears during
the first three years of life, and is the result of a neurological disorder that affects the
normal functioning of the brain, impacting development in the...
Quorum sensing (Microbiology); Cellular signal transduction; Bacterial genetics
Quorum sensing in the oral pathogen Aggregatibacter actinomycetemcomitans is dependent upon the soluble signaling molecule AI-2, but it is not known how the initial detection of AI-2 is coupled to the downstream regulation of gene expression that...
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...
