Numerical investigation of wire coil heat transfer augmentation
No full textThe enhancement of turbulance through the use of turbulators has been studied extensively in the past. The copper coil insert has been tested via experimental research which presented data sufficient enough to conclude that such turbulators would be effective when used in all high-heat load/flux components at the Advanced Photon Source at Argonne National Laboratory. The present investigation discusses the numerical simulation of the wire coil insert using spectral element analysis. The non-dimensionalized heat transfer coefficient, Nusselt Number, and eddy diffusivity are used to draw conclusions regarding main transport mechanisms and optimal design parameters of the wire. The optimal parameter case, as determined by Collins et al. is analyzed here. This analysis confirms the conclusion of previous experimental research, shows that the increase of heat transfer due to the turbulators is not highly correlated to material choice of the turbulator, and maintains that the main heat transfer mechanism is turbulent mixing.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Anne Goering, accepted the attached license on 2016-04-26 at 11:44.The student, Anne Goering, submitted this Thesis for approval on 2016-04-26 at 11:51.This Thesis was approved for publication on 2016-04-27 at 14:14.DSpace SAF Submission Ingestion Package generated from Vireo submission #9505 on 2016-07-07 at 13:50:57Made available in DSpace on 2016-07-07T20:35:19Z (GMT).

ST2249-MRSA-III: a second major recombinant methicillin-resistant Staphylococcus aureus clone causing healthcare infection in the 1970s
No full textTyping of healthcare-associated methicillin-resistant Staphylococcus aureus (MRSA) from Australia in the 1970s revealed a novel clone, ST2249-MRSA-III (CC45), present from 1973 to 1979. This clone was present before the Australian epidemic caused by the recombinant clone, ST239-MRSA-III. This study aimed to characterize the genome of ST2249-MRSA-III to establish its relationship to other MRSA clones. DNA microarray analysis was conducted and a draft genome sequence of ST2249 was obtained. The recombinant structure of the ST2249 genome was revealed by comparisons to publicly available ST239 and ST45 genomes. Microarray analysis of genomic DNA of 13 ST2249 isolates showed gross similarities with the ST239 chromosome in a segment around the origin of replication and with ST45 for the remainder of the chromosome. Recombination breakpoints were precisely determined by the changing pattern of nucleotide polymorphisms in the genome sequence of ST2249 isolate SK1585 compared with ST239 and ST45. One breakpoint was identified to the right of oriC, between sites 1014 and 1065 of the gene D484_00045. Another was identified to the left of oriC, between sites 1185 and 1248 of D484_01632. These results indicate that ST2249 inherited approximately 35.3% of its chromosome from an ST239-like parent and 64.7% from an ST45-like parent. ST2249-MRSA-III resulted from a major recombination between parents that resemble ST239 and ST45. Although only limited Australian archival material is available, the oldest extant isolate of ST2249 predates the oldest Australian isolate of ST239 by 3 years. It is therefore plausible that these two recombinant clones were introduced into Australia separately
How the Nuremberg Trials Set Precedence for Future War Crimes Tribunals to be Conducted: Comparing Reichsmarschall Hermann Goering and Former President of Serbia Slobodan Milosevic
No full textabstract: The purpose of this thesis is to establish how the Nuremberg trials set precedence for future war crime tribunals like the ICTY (the first tribunal since Nuremberg). An analyses of Hermann Goering is given in order to illustrate how his case, from its arguments and indictments to the structure of the court, is similar to Slobodan Milosevic's. These two are the most likely candidates to compare to due to their high ranking position in the political structure of their regime as well as having remarkable similarities to the conditions of their trail by the two tribunal
Computer control of engine-transmission system for improving fuel economy
No full textA control strategy for improving tractor operating efficiency was proposed in this study. The strategy is to control an engine and a continuously variable transmission (CVT) in such a way that the engine works along a line of minimum brake specific fuel consumption (BSFC).Analysis and computer simulation indicated that an engine-CVT system can operate stably and track the desired minimum BSFC curve. Fuel savings of over 25% can be achieved with the proposed control strategy, as compared to a conventional tractor. Design of the control for the engine-CVT system can be achieved by designing engine speed control and CVT ratio control independently, provided the controllers are integrated through the minimum BSFC curve. The engine-CVT system can be viewed as an augmented engine, to which a conventional power train can be added to provide a range of ground speeds. The engine-CVT system can be interpreted as an adaptive control system with the CVT ratio being updated continuously to compensate for load variations.A diesel engine was coupled to a V-belt CVT in the laboratory to validate the proposed control strategy. Test results, indeed, supported the analysis and simulation experiments. Compared to governor-controlled engines on farm tractors, fuel savings of over 15% was achieved with the prototype system, and fuel savings of over 25% could be gained with improved hardware.Made available in DSpace on 2011-05-07T13:50:58Z (GMT).

Allelic variation in genes encoding Panton–Valentine leukocidin from community-associated Staphylococcus aureus
No full textABSTRACTCommunity-associated methicillin-resistant Staphylococcus aureus isolates characteristically contain the genes for Panton–Valentine leukocidin (PVL), which is a proposed virulence factor. To determine whether different alleles of the PVL genes lukS-PV and lukF-PV occur, and whether they are associated with specific genetic lineages of S. aureus, sequences from 28 S. aureus isolates, representing four different multilocus sequence types, and bacteriophages SLT and PVL were compared. Seven nucleotide polymorphisms were identified, which defined three groups of the lukS-PV and lukF-PV sequence. Only one polymorphism resulted in an amino-acid change. Bacteriophage SLT and isolates of bacteriophage type 80/81 contained the prototypic (founder) lukS-PV and lukF-PV sequence. The alleles were not lineage-specific
Google in China : examining hegemonic identification strategies in organizational rhetoric
No full textIndiana University-Purdue University Indianapolis (IUPUI)The author employs Hoffman and Ford’s method for analyzing organizational rhetoric to examine the discourse of Google, Inc. Employing a hybrid method, built on rhetorical criticism which incorporates elements of organizational communication theory, the analysis examines identity rhetoric present in Google’s discourse regarding its operations in China. Using this approach, the author leverages the method to critically examine hegemonic aspects of the discourse in order to examine how Google constructs its Western consumer based audience regarding online privacy and free speech
From Learning to Love: Schools, Pastoral Care and Canon Law in the Middle Ages. Essays in Honour of Joseph W. Goering
No full textR. James Long is a contributing author, The Plurality of Platonic Forms and Trinitarian Simplicity: A Conundrum and its Resolution by the Early Oxford Masters.
Book description: The essays in this volume show how the teaching of law and theology in the medieval schools was part of a pastoral project to foster a just Christian society and to lead souls to contemplation of God. With subjects ranging from scholastic debates about divine simplicity to disputes between parishioners over their reputations, these studies take us across Europe, from the eleventh to the fifteenth centuries, although the heart of the volume covers England and northern France in the decades around 1200. The collection reveals a culture with many threads of mutual influence connecting the learning of the schools, the administration of the Church, the perspectives of professionals in law and theology, and the stories, practices, and devotion of the laity. The first section of the volume considers medieval masters and examines both their subjects of intellectual inquiry and their pedagogical methods, as reflected in the particular textual and manuscript practices developed in the schools. The second section considers how clerics applied learning acquired in the schools in their roles as pastors, judges, and administrators. The final section gathers essays on those aspects of religious culture manifested in popular piety, liturgy, and hagiography. Diverse in methods and scope, these essays nevertheless share a common aim: to honour the remarkable scholarly achievement of Joseph Ward Goering. Although best known for his work on scholastic theology and pastoralia, his interests have ranged from hagiography to visual culture, and this volume reflects the interdisciplinary breadth and coherence of his work. This book presents original studies from many fields, including history, law, language and literature, theology, philosophy, and musicology, along with some editions of hitherto unpublished texts, as a tribute to Joe’s role as a beloved mentor to medievalists from many disciplines.https://digitalcommons.fairfield.edu/philosophy-books/1039/thumbnail.jp
