Basic Writers Writing In Their Zone Of Proximal Development Through Intertextual Links, Cynda Alexander

Theses and Dissertations

Students in Basic Writing classes are separated from their peers who are mainstreamed into regular composition classes, stigmatizing them as having substandard skills. Preconditioned to question their ability to write, they arrive in class with zero confidence and varying degrees of ability to construct meaning. Students rely on their prior knowledge to fill in the gaps between texts. Their ability to accommodate and assimilate new information to their prior knowledge is dependent on their ability to link with it. Since semiotician Julia Kristeva first used the term intertextuality in 1967, there has been a great deal of interest in intertextuality, …

Simulation Of Mobile Treatment Monitoring System, Emre Ermisoglu

Theses and Dissertations

Noncompliance is the main reason for treatment failure. Approximately 50 to 75% of patients misuse their medication due to forgetfulness and busy schedule. Instead of heavily depending on patient's memory for following medication deadlines, we propose a new automated medication helper called "Mobile Treatment Monitoring System" to help patients take their medication on time. Among other technologies that help patients to follow up their medication such as Pill Organizers, Medication Reminders, and Pill Dispensers, using remote treatment monitoring system appears to be a promising technology because system creates a direct link between doctor and patient so doctor will be notified …

An Objective Assessment Of Fetal Neurological Maturation Based On The Co-Variation Of Brain And Heart Rate Patterns, Srinivasan Vairavan

Theses and Dissertations

An in-utero neurological assessment would aid clinicians in an early detection of fetal neurological distress. However, accessing the fetal brain signal has remained a major challenge. With the advent of Superconducting Quantum Interference Device (SQUID) technology, magnetoencephalogram (MEG), is now an established technique for recording human brain activity. This technique is non-invasive and records the magnetic fields corresponding to electric currents generated by the neurons in the brain. Based on MEG technology, a first-of-a-kind device, named SARA (SQUID Array for Reproductive Assessment), was specifically designed and installed in the Department of Obstetrics and Gynecology, University of Arkansas for Medical Sciences, …

Hemiscorpius Novaki Sp. N. From Somaliland (Scorpiones: Hemiscorpiidae), František Kovařík, Tomáš Mazuch

Euscorpius

Hemiscorpius novaki sp. n. from Somaliland is described and compared with other African species of the genus. The new species is characterized chiefly by the total length of 40–46 mm; yellow to yellowish-brown color with pedipalp fingers reddish brown to black, darker than the chela; slightly longer metasoma in the male than in the female. These characters distinguish H. novaki sp. n. from H. somalicus Lourenço, 2011. The third African species of the genus, H. tellinii Borelli, 1904, is known only from the female holotype, which differs from females of H. novaki sp. n. in having much less pronounced granulation …

Bistability Versus Bimodal Distributions In Gene Regulatory Processes From Population Balance., Che-Chi Shu, Anushree Chatterjee, Gary Dunny, Wei-Shou Hu, Doraiswami Ramkrishna

School of Chemical Engineering Faculty Publications

In recent times, stochastic treatments of gene regulatory processes have appeared in the literature in which a cell exposed to a signaling molecule in its environment triggers the synthesis of a specific protein through a network of intracellular reactions. The stochastic nature of this process leads to a distribution of protein levels in a population of cells as determined by a Fokker-Planck equation. Often instability occurs as a consequence of two (stable) steady state protein levels, one at the low end representing the “off” state, and the other at the high end representing the “on” state for a given concentration …

Energy-Efficient And Secure Framework For Wireless Sensor Networks, Murat Al

Theses and Dissertations

Protocol designers for wireless sensor networks (WSNs) have to consider many constraints including limited power and computing capacity of the sensing devices that make WSNs more vulnerable to attacks than wired or more resourceful wireless networks. The availability of a message for the adversary is the starting point for attacks on data confidentiality. This work proposes an end-to-end Message Dispersion Mechanism (MDM) to improve data confidentiality by significantly reducing message interception opportunities by potential adversaries in the first place. With MDM, a resource constrained sensor device first divides a message into several segments, encrypts them, and distributes them to a …

Modeling And Simulation Of Hpc System Through Job Scheduling Analysis, William Bradley Hurst

Theses and Dissertations

The sophistication of the devices through which a man shapes his world are the tool-marks of his development upon history. One device currently shaping the lives of man is the High Performance Computer (HPC) system. HPC systems have been described as ``a game changing technology (King and BusinessWeek, 2010).'' The reason for HPC systems to be declared ``a game changing technology (King and BusinessWeek, 2010)'' comes from the fact that it is cheaper for a manufacturer to conduct thousands of tests in virtual space, than it is to try multiple experimental designs in the physical world. Through capabilities of HPC …

A Moderate Elevation Of Circulating Levels Of Igf-I Does Not Alter Erbb2 Induced Mammary Tumorigenesis, Robert K. Dearth, Isere Kuiatse, Yu-Fen Wang, Lan Liao, Susan G. Hilsenbeck, Powel H. Brown, Jianming Xu, Adrian V. Lee

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Background

Epidemiological evidence suggests that moderately elevated levels of circulating insulin-like growth factor-I (IGF-I) are associated with increased risk of breast cancer in women. How circulating IGF-I may promote breast cancer incidence is unknown, however, increased IGF-I signaling is linked to trastuzumab resistance in ErbB2 positive breast cancer. Few models have directly examined the effect of moderately high levels of circulating IGF-I on breast cancer initiation and progression. The purpose of this study was to assess the ability of circulating IGF-I to independently initiate mammary tumorigenesis and/or accelerate the progression of ErbB2 mediated mammary tumor growth.

Modification By Frailty Status Of Ambient Air Pollution Effects On Lung Function In Older Adults In The Cardiovascular Health Study, Sandrah P. Eckel, Thomas A. Louis, Paulo H.M. Chaves, Linda P. Fried, Helene G. Margolis

Johns Hopkins University, Dept. of Biostatistics Working Papers

Older adult susceptibility to air pollution health effects is well-recognized. Advanced age may act as a partial surrogate for conditions associated with aging. The authors investigated whether gerontologic frailty (a clinical health status metric) modified the effects of ambient ozone or particulate matter (PM10) air pollution on lung function in 3382 older adults using 7 years of followup data from the Cardiovascular Health Study (CHS) and the CHS Environmental Factors Ancillary Study. Monthly average pollution and annual frailty assessments were related to up to 3 repeated measurements of lung function using novel cumulative summaries of pollution and frailty histories that …

Intraspecific Aflatoxin Inhibition In Aspergillus Flavus Is Thigmoregulated, Independent Of Vegetative Compatibility Group And Is Strain Dependent, Changwei Huang, Archana Jha, Rebecca Sweany, Catherine Derobertis, Kenneth E. Damann

Faculty Publications

Biological control of preharvest aflatoxin contamination by atoxigenic stains of Aspergillus flavus has been demonstrated in several crops. The assumption is that some form of competition suppresses the fungus's ability to infect or produce aflatoxin when challenged. Intraspecific aflatoxin inhibition was demonstrated by others. This work investigates the mechanistic basis of that phenomenon. A toxigenic and atoxigenic isolate of A. flavus which exhibited intraspecific aflatoxin inhibition when grown together in suspended disc culture were not inhibited when grown in a filter insert-plate well system separated by a.4 or 3 μm membrane. Toxigenic and atoxigenic conidial mixtures (50:50) placed on both …

Stromatolitic Knobs In Storrs Lake, San Salvador, Bahamas: Insights Into Organomineralization, Alexandre J. Fowler

Master's Theses

Storrs Lake, a hypersaline lake on the east coast of San Salvador Island, Bahamas, contains well-developed microbial mats, some of which have developed calcified structures called microbialites. Many of these microbialites are laminated, and therefore classified as stromatolites. This study focuses on small stromatolitic knobs located in the southern portion of Storrs lake, which are still actively forming, to gain insights into the early stages of stromatolite formation. These knobs appear to be forming as the result of in situ micritic precipitation mediated by both photosynthetic and heterotrophic microbial metabolisms. By comparing these small stromatolitic knobs to larger stromatolitic heads …

Automation Of Orthodontic Wire Tester For Performing Three Point Bending Tests, Adithya Venkatesan

Master's Theses

Abstract

Understanding the biomechanical factors in orthodontics is important in order to improve the overall effectiveness of actual clinical treatment. An accurate method to study the threedimensional (3D) force systems and the resulting movements of teeth during orthodontic treatment is needed along with the understanding of the material properties of any orthodontic wire. Until recently, most of the orthodontic biomechanics literature was limited to twodimensional experimental studies. Recent advances in threedimensional computer modeling have also been developed but have been limited to the manual control of tooth movement. Overall, there is very little published evidence in the literature on the …

Fabrication And Characterization Of Zno/Cuo Core-Shell Nanowire Arrays, Kuo-Ting Liao

Master's Theses

Research into nanomaterials has become more and more popular because of their unique properties compared to bulk materials. Amongst various functional materials, zinc oxide (ZnO), with a direct electron energy band gap of 3.34 eV at room temperature, is an important optoelectronic material with an intrinsically n-type semiconducting property. However, to form a p-type ZnO semiconductor is still a challenge. Copper oxide (CuO), compared to ZnO, has a much smaller band gap, 1.2 eV, and shows an intrinsically p-type semiconducting property. It has been suggested that when CuO is alloyed with ZnO properly, a p-n semiconductor heterojunction can be formed …

Effect Of Prostaglandin E2 On Mechanical Stresses Applied By Mc3t3-E1 Osteoblast-Like Cells On A Soft Hydrogel Substrate, Abhijit Deb Roy

Master's Theses

Osteoblasts are sensitive to mechanical stimuli and release Prostaglandin E2 (PGE2) when exposed to a fluid shear stress. The exact mechanism by which these cells sense mechanical stress is not well established. A study of the stresses applied by the osteoblasts, under the influence of PGE2, on a hydrogel provided information regarding intercellular-communication via changes in the substrate surface pattern.

A digital image correlation program was developed using the Levenberg-Marquardt optimization algorithm to analyze images and compare the deformations between pairs of images. Comparisons of images before and after the addition of PE2 to the media showed differences in the …

Dissolved Organic Matter Characterization And Impact On Mercury Binding In An Urbanizing Watershed, Mykel Mendes

Master's Theses

Dissolved organic matter (DOM) is ubiquitous in aquatic ecosystems, interacting with and controlling the bioavailability and transport of mercury (Hg) and other trace metals through complexation. The complexation of ionic Hg (Hg²⁺) with DOM can either limit methyl mercury (MeHg) bioavailability or increase MeHg production by stimulating microbial growth. While substantial investigations have examined Hg-DOM interactions in forested ecosystems, little research has been conducted on the Hg-DOM relationship within an urbanized river setting subjected to various anthropogenic sources. The various runoff and pollutant sources vary in DOM quality and character. Three sources of organic matter from the North …
