Investigation of mechanisms governing emission of odorants

The literature identifies several models that describe inter-phase mass transfer, key to the emission process. While the emission process is complex and these models may be more or less successful at predicting mass transfer rates, they identify three key variables for a system involving a liquid and an air phase in contact with it: • A concentration (or partial pressure) gradient driving force; • The fluid dynamic characteristics within the liquid and air phases, and • The chemical properties of the individual components within the system. In three applied research projects conducted prior to this study, samples collected with two well-known sampling devices resulted in very different odour emission rates. It was not possible to adequately explain the differences observed. It appeared likely, however, that the sample collection device might have artefact effects on the emission of odorants, i.e. the sampling device appeared to have altered the mass transfer process. This raised the obvious question: Where two different emission rates are reported for a single source (differing only in the selection of sampling device), and a credible explanation for the difference in emission rate cannot be provided, which emission rate is correct? This research project aimed to identify the factors that determine odour emission rates, the impact that the characteristics of a sampling device may exert on the key mass transfer variables, and ultimately, the impact of the sampling device on the emission rate itself. To meet these objectives, a series of targeted reviews, and laboratory and field investigations, were conducted. Two widely-used, representative devices were chosen to investigate the influence of various parameters on the emission process. These investigations provided insight into the odour emission process generally, and the influence of the sampling device specifically

The Military Image in the Poetry of A. E. Housman

This thesis analyzes the military image in the poems of A. E. Housman. The first section is a brief biographical sketch which stresses those incidents of Housman\u27s life that most influenced his personality and poetry. Section two is an introduction to Housman\u27s association and contact with the military and points out influences on his military poems. Section three analyzes those military poems which have autobiographical significance for the author. The fourth section is an explanation of Housman\u27s belief that the military life is the best possible life; it also analyzes the virtues and value system of the soldier. The final section discusses the military as an escape from the misery of life, an escape either through becoming an automatonic soldier, or by reaching the ultimate in life, a brave death. All poems cited are from The Collected Poems of A. E. Housman, published by Henry Holt and Company, New York, in 1940

Planar graphs : a historical perspective.

The field of graph theory has been indubitably influenced by the study of planar graphs. This thesis, consisting of five chapters, is a historical account of the origins and development of concepts pertaining to planar graphs and their applications. The first chapter serves as an introduction to the history of graph theory, including early studies of graph theory tools such as paths, circuits, and trees. The second chapter pertains to the relationship between polyhedra and planar graphs, specifically the result of Euler concerning the number of vertices, edges, and faces of a polyhedron. Counterexamples and generalizations of Euler\u27s formula are also discussed. Chapter III describes the background in recreational mathematics of the graphs of K5 and K3,3 and their importance to the first characterization of planar graphs by Kuratowski. Further characterizations of planar graphs by Whitney, Wagner, and MacLane are also addressed. The focus of Chapter IV is the history and eventual proof of the four-color theorem, although it also includes a discussion of generalizations involving coloring maps on surfaces of higher genus. The final chapter gives a number of measurements of a graph\u27s closeness to planarity, including the concepts of crossing number, thickness, splitting number, and coarseness. The chapter conclused with a discussion of two other coloring problems - Heawood\u27s empire problem and Ringel\u27s earth-moon problem

An Introduction to Police Operations and Methods: The Connection to Law and History

An Introduction to Police Operations and Methods: The Connection to Law and History textbook provides an overview of the complex and evolving role of police in a modern democratic society. Police officers are expected to respond to the demands of competing constituencies and resolve complex societal and individual problems. The invocation of the formal criminal justice system and the use of force to accomplish lawful objectives is sometimes required. In order to understand how and why the police operate as they do, the history of organized law enforcement is examined. Attention is given to the selection and training of qualified officers. Given that patrol work and criminal investigations constitute a significant portion of the police function; police operations, behavior, and culture are also addressed. Underlying the day-to-day work of police officers are the pervasive issues of ethics and discretion that may lead to abuses of power, deviance, and, corruption. The text concludes with an overview of police and the rule of law by identifying significant Supreme Court decisions that have shaped the limits of law enforcement authority.https://aquila.usm.edu/textbooks/1000/thumbnail.jp

Sharing Faculty Collaboration Success Stories

At the University of Southern Mississippi, and across the country in Academic Libraries, the mantra for Public Services Librarians is to develop relationships with your assigned faculty members and to work with them collaboratively. This presentation will highlight three success stories from a new librarian’s first year: a reinvention of basic library instruction for our English 102 course; office hours and a pathfinder for our History 101 course; and, coauthoring an open access textbook (with a cop!). The presenter will encourage the audience to share their own success stories so that we can all grow together. Attendees will leave with a set of tips and tricks for developing their own successful faculty relationships

Identification of the proteins, including MAGEG1, that make up the human SMC5-6 protein complex

The SMC protein complexes play important roles in chromosome dynamics. The function of the SMC5-6 complex remains unclear, though it is involved in resolution of different DNA structures by recombination. We have now identified and characterized the four non-SMC components of the human complex and in particular demonstrated that the MAGEG1 protein is part of this complex. MAGE proteins play important but as yet undefined roles in carcinogenesis, apoptosis, and brain development. We show that, with the exception of the SUMO ligase hMMS21/hNSE2, depletion of any of the components results in degradation of all the other components. Depletion also confers sensitivity to methyl methanesulfonate. Several of the components are modified by sumoylation and ubiquitination

The effect of health insurance coverage and the doctor-patient relationship on health care utilization in high poverty neighborhoods

African Americans have higher rates of mortality than whites who are the same age and sex. We hypothesize that in low socioeconomic status neighborhoods, having health insurance coverage and a regular health care provider increases the likelihood of receiving diagnostic tests for cardiovascular disease and diabetes. We use data from a random two-stage cluster sample of 230 adults living in high poverty census tracts to examine the effects of insurance coverage and having a regular doctor on the likelihood receiving diagnostic tests for high cholesterol, high blood sugar, and blood pressure. We find that health insurance coverage increases the odds of having a regular health care provider (p \u3c 0.05) and of receiving the diagnostic tests (p \u3c 0.05). Having a regular doctor mediates the effect of insurance coverage on the likelihood of receiving the tests, especially when the participant can report the physician\u27s name
