Comparison Of Earth-Air And Earth-Water Ground Tube Heat Exchangers For Residentialal Application, Christophe T’Joen, Liping Liu, M. De Paepe

International Refrigeration and Air Conditioning Conference

Earth-air systems are already commonly applied as a passive technique to reduce the overall energy use of buildings by reducing the required cooling or heating demand. However, they often require large surface area for their installation, and make use of large diameter tubes to reduce the pressure drop. As an alternative, waterearth systems are being considered. To explore these two options, one dimensional analytical models were derived. The impact of different design parameters, including tube length, tube diameter, fluid flow rate, etc., have been investigated. For the earth-air system, it is shown that for high Reynolds numbers, the soil resistance …

Domestic Hot Water Supply For Multiple Familiy Dwellings Using Heat Pumps, Bernhard Vetsch, Andreas Gschwend, Stefan S. Bertsch

International Refrigeration and Air Conditioning Conference

In multiple family dwellings of central Europe heat pumps are not only used for space heating but also increasingly for domestic hot water (dhw) supply. The water is often heated in a centralized or decentralized installation with a large distribution network. This leads to the combination of heat pumps with various trace heating systems to ensure both comfort and protection from legionella disease. The COP of the heat pump can be greatly affected by the choice of the heat tracing system which influences the overall efficiency (OE) of the domestic hot water supply system significantly. In this study several heat …

Efficient Coding And Statistically Optimal Weighting Of Covariance Among Acoustic Attributes In Novel Sounds, Keith Kluender R., Christian E. Stilp

Department of Speech, Language, and Hearing Sciences Faculty Publications

To the extent that sensorineural systems are efficient, redundancy should be extracted to optimize transmission of information, but perceptual evidence for this has been limited. Stilp and colleagues recently reported efficient coding of robust correlation (r =. 97) among complex acoustic attributes (attack/decay, spectral shape) in novel sounds. Discrimination of sounds orthogonal to the correlation was initially inferior but later comparable to that of sounds obeying the correlation. These effects were attenuated for less-correlated stimuli (r =. 54) for reasons that are unclear. Here, statistical properties of correlation among acoustic attributes essential for perceptual organization are investigated. Overall, simple strength …

Conceptual Changes To The Definition Of Borderline Personality Disorder Proposed For Dsm-5, Douglas B. Samuel, Joshua D. Miller, Thomas A. Widiger, Donald R. Lynam, Paul A. Pilkonis, Samuel A. Ball

Department of Psychological Sciences Faculty Publications

The DSM-5 Personality and Personality Disorders Work Group proposed the elimination of diagnostic criterion sets in favor of a prototype matching system that defines personality disorders using narrative descriptions. Although some research supports this general approach, no empirical studies have yet examined the specific definitions proposed for DSM-5. Given the wide interest in borderline personality disorder (BPD), it is crucial to determine how this methodological shift might affect the content and conceptualization of the diagnosis. Eighty-two experts on BPD provided ratings of the DSM-IV-TR or DSM-5 version of BPD in terms of 37 traits proposed for DSM-5. Analyses revealed significant …

Learning And Transfer Of Category Knowledge In An Indirect Categorization Task, Sebastien Helie, F Gregory Ashby

Department of Psychological Sciences Faculty Publications

Knowledge representations acquired during category learning experiments are ‘tuned’ to the task goal. A useful paradigm to study category representations is indirect category learning. In the present article, we propose a new indirect categorization task called the “Same” – “Different” categorization task. The same-different categorization task is a regular same-different task, but the question asked to the participants is about the stimulus category membership instead of stimulus identity. Experiment 1 explores the possibility of indirectly learning rule-based and information-integration category structures using the new paradigm. The results suggest that there is little learning about the category structures resulting from an …

Development And Evaluation Of An Instrument To Measure Mother-Infant Togetherness After Childbirth, Carol Lawrence

Electronic Theses and Dissertations

No existing measure to date captures mother-infant togetherness. A valid measure of togetherness is essential to engage in evidence-based practice, evaluate obstetric delivery models and nursing interventions, and measure the level of togetherness which promotes optimal maternal-infant outcomes. When together and in close proximity, a women and her infant have access to one another to allow for mutual caregiving or caregiving on cue. A new measure entitled the Mother-Infant Togetherness Scale (MITS) was developed based on a review of the literature and conceptual framework of Mother-Newborn Mutual Caregiving. The MITS is a 35- item instrument composed of four subscales that …

A New Semantic Similarity Join Method Using Diffusion Maps And Long String Table Attributes, Bilal Hani Hawashin

Wayne State University Dissertations

With the rapid increase of the distributed data sources, and in order to make information integration, there is a need to combine the information that refers to the same entity from different sources. However, there are no global conventions that control the format of the data, and it is impractical to impose such global conventions. Also, there could be some spelling errors in the data as it is entered manually in most of the cases. For such reasons, the need to find and join similar records instead of exact records is important in order to integrate the data. Most of …

Hallowed Ground: Literature And The Encounter With God In Post-Reformtion England, C. 1550 - 1704, Michael Thomas Martin

Wayne State University Dissertations

This dissertation examines the ways in which the encounter with God is figured in post-Reformation English writing between the years 1550 and 1704. The introduction contextualizes the ways in which individuals might encounter God within cultural and historical circumstances of the period: the gradual disappearance of the tradition of spiritual direction that accompanied the suppression of Catholicism in England during the period and the growing influence of more purely "scientific" modes of inquiry, especially after Descartes. Because of these changes, the ways the encounter with God could be experienced were also changing. The introduction also shows how developments in religious …

Wayne State University Dissertations

The details of the dual-fuel combustion of n-heptane and ethanol were investigated in an optically accessible engine representative of light-duty applications. Experimental work involved the application of optical diagnostics such as high-speed imaging of combustion chemiluminescence and soot radiation, spectral measurements and laser induced fluorescence. At the same time, the experimental conditions have been replicated using numerical simulation of chemically reactive in-cylinder flow.

The numerical simulation results, which showed good agreement with the experimental data across several validation approaches, provided an improved understanding of the mechanism responsible for the control of the rate of combustion for dual-fuel operation. The comparison …

Epistemic Communities And Regional Governance: Policy Development In Municipal Finance Reform, Shanthi Karuppusamy

Wayne State University Dissertations

In recent times, the US has undergone significant changes in how regional governance is conceptualized and the focus has shifted from government to governance and from governmental consolidation to problem solving (Barnes and Foster, 2011). Policy makers' quest for interjurisdictional responses to the financial crisis and the recession has rekindled interest in the topic of regional governance. However, the economic, social and technical changes of the recent decades, which have now assimilated in US urban regions, fundamentally challenge existing dominant ways of thinking about regional governance and call for more useful analytic frameworks (Bollens, 1997; Barnes and Foster, 2011). This …

However, the role of this downregulation in arterial pathogenesis is unknown. Hypothesis : Downregulation of SM22 may actively contribute to arterial pathogenesis. Methods : Five Sm22 knockout (Sm22^-/-) mice and their wild type littermates were subjected to carotid artery denudation, an artery injury model. Analyses were conducted on carotid arteries 2 weeks after injury. Primary VSMCs were isolated from mouse aortas and investigated individually at passage 2 to 4. Sm22 knockdown was …

Determinants Of Cns Adult Neurogenesis Are Sex, Hormones, Mouse Strain, Age, And Brain Region, Carrie Lynn Tatar

Wayne State University Dissertations

Multiple sclerosis is a sexually dimorphic (SD) disease that causes oligodendrocyte death but SD of glial cells is poorly studied. Here, we analyze SD of neural progenitors in 6-8wk and 6-8mo normal C57BL/6, SJL/J and BALB/c mice in the subventricular zone (SVZ), dorsolateral horn (DLC), corpus callosum (CC), and parenchyma. With a short 2 h BrdU pulse, no gender and strain differences are present at 6-8wk. At 6-8mo, the number of BrdU+ cells decreases 2-fold in both sexes, strains and regions indicating a common aging mechanism regulates BrdU incorporation. Strikingly, 2X more BrdU+ cells are found in all brain regions …

Finally, a mechanism is proposed for the first time in the literature …

Investigation Of The Absorptive Potential Of Polymeric Nanoparticles Across The Lungs And Their Development For Efficient Systemic Delivery Following Pulmonary Administration, Abdul Khader Mohammad

Wayne State University Dissertations

The lungs are an attractive route for drug delivery due to their high epithelial surface area available for absorption, a thin epithelium and extensive vasculature to name a few. Accordingly, a vast number of small molecule drugs, peptides, and proteins have been used to investigate their translocation across the lungs with many of the tested candidates showing excellent pharmacokinetics following pulmonary administration. Findings from all these studies over the years have strongly established the lungs as a route for drug delivery of small molecules and proteins. Nanoparticles on the other hand have gained increasing interest in drug delivery due to …

Identification Of Transcriptional Mechanisms Downstream Of Nf1 Gene Defeciency In Malignant Peripheral Nerve Sheath Tumors, Daochun Sun

Wayne State University Dissertations

Malignant peripheral nerve sheath tumor (MPNST) is a type of soft tissue sarcoma that occurs in carriers of mutations in the neurofibromatosis type I gene (Nf1) as well as sporadically. Plexiform neurofibromas in NF1 patients have a significant risk of developing into MPNSTs leading to increased morbidity and mortality from this syndrome. Surgery is the primary intervention but it is not always effective due to the tendency of MPNSTs to infiltrate the surrounding tissue or grow in an inoperable location. Neurofibromin, the protein coded by the Nf1 gene, functions as a GTPase activating protein (GAP) whose mutation leads to constitutive …

Patients become paralyzed shortly after symptom onset and typically die within one to five years of pulmonary complications. ALS is a relatively rare disease, with an overall incidence of approximately 2 in 100,000 people per year and a prevalence of about 5 in 100,000 people. It is typically associated with increasing age and has a slight male prevalence, with a male to female ratio of approximately 3:2. ALS is classified as either familial (the less …

Examining Autoimmune Sequelae During Cancer Immunotherapy In A Combined Autoimmune Thyroiditis And Tumor Mouse Model, Suresh Kari

Wayne State University Dissertations

Some clinical trials of immunotherapeutic agents against cancers have resulted in the development of autoimmune sequelae, including autoimmune thyroiditis. It has been suggested that the immunotherapy resulted in an alteration in the immunoregulatory mechanism(s). Using experimental autoimmune thyroiditis (EAT), a mouse model of Hashimoto's thyroiditis (HT), the importance of regulatory T cells (Tregs) has been well established; inhibition of Tregs leads to enhanced thyroiditis with repeated doses of mouse thyroglobulin (mTg) without adjuvant. To simulate cancer patients, we developed a combined EAT and tumor model in our EAT-susceptible mice (CBA/J). In first establishing the tumor model, we found Treg depletion …
