Saari’S Homographic Conjecture Of The Three-Body Problem, Florin Diacu, Toshiaki Fujiwara, Ernesto Pérez-Chavela, Manuele Santoprete

Mathematics Faculty Publications

Saari’s homographic conjecture, which extends a classical statement proposed by Donald Saari in 1970, claims that solutions of the Newtonian n-body problem with constant configurational measure are homographic. In other words, if the mutual distances satisfy a certain relationship, the configuration of the particle system may change size and position but not shape. We prove this conjecture for large sets of initial conditions in three-body problems given by homogeneous potentials, including the Newtonian one. Some of our results are true for n ≥ 3.

Un Autre Monde Est Possible: Création Et Résistance Dans L’Oeuvre D’Ousmane Sembène, David Murphy

Présence Francophone: Revue internationale de langue et de littérature

During an artistic career that spanned half a century, Ousmane Sembène often played a pioneering role. However, although the many awards he received constitute recognition of the artistic quality of his work, his literary and cinematic output is best known for its denunciation of colonial and neo-colonial injustices. This article argues that Sembène’s importance is not solely political, and nor should it be limited to his role as a pioneer of African cinema. Sembène was also a great artist who developed a profound refl ection on his practice both as a writer and as a filmmaker. The article will trace …

Du Néoréalisme En Afrique: Une Relecture De Borom Sarret, Sada Niang

Présence Francophone: Revue internationale de langue et de littérature

Critical evaluations of African cinema have tended in the past to confi ne the analysis of this corpus to its content. In books and articles published earlier, the colonial and postcolonial history of the continent abound, social dramas are explained at length, thefts at all levels, cultural mystifi cation, corruption as well as violence are amply described. The insights of such an approach notwithstanding, the aesthetic sources of African cinema are not limited to the rural and the traditional. Through a comparison of Vittorio De Sica Bicycle Thief and Sembène’s Borom Sarret, this paper argues that african cinema inserted itself …

Numerical Modeling Of A Stenosed Artery Using Mathematical Model Of Variable Shape, S. Mukhopadhyay, G. C. Layek

Applications and Applied Mathematics: An International Journal (AAM)

The intention of the present work is to carry out a systematic analysis of flow behavior in a two-dimensional tube (modeled as artery) with a locally variable shaped constrictions. The simulated artery, containing a viscous incompressible fluid representing the flowing blood, is treated to be complaint as well as rigid tube. The shape of the stenosis in the arterial lumen is chosen to be symmetric as well as asymmetric about the middle cross section perpendicular to the axis of the tube in order to improve resemblance to the in-vivo situation. The constricted tube is transformed into a straight tube and …

Finding Life: An Organic Model Of Renewal For Existing Churches, Thomas E. Rester Jr.

Doctor of Ministry

Statistics reveal most existing mainline churches are small, declining, and unable to minister effectively in their current environment. Rising stress is the result for these congregations. For mission and ministry to continue in many of these places, the stress must become an opportunity to release a deeper organic understanding of identity and ministry within the fluid postmodern context.

Chapter 2 presents biblical materials from the book of Acts. Focusing on Acts 15, we discover that in a moment of fil"eat stress and confusion, the church was able to e change and evolve to find new life in the midst of …

La Inmigración Africana A España Y Argentina En La Época De La Globalización, Laura K. Cullenward

Hispanic Studies Honors Projects

International migration, with its complex web of economic, social, demographic, and political consequences, is a theme that dominates national and international interests. This thesis explores a connection between illegal African immigration to Spain and a recent phenomenon of Senegalese immigration to Argentina through an examination of historical trajectories of immigration, legal and illegal entries, and migration legislation. In particular the focus will be on the role of Spanish national migration law and border control as a deterrent against illegal African immigration and a resultant wave of Senegalese immigrants representing a new phenomenon of ecologically pushed migration from Sub-Saharan Africa.

For example, a few of the most prevalent variables on the Web sites were the general contact information, staff information, e-mail …

Hydraulic Actuated Automotive Cooling Systems - Nonlinear Control And Test, John Wagner, M H. Salah, P M. Frick, D M. Dawson

Publications

The replacement of traditional automotive mechanical cooling system components with computer controlled servo-motor driven actuators can improve temperature tracking and reduce parasitic losses. The integration of hydraulic actuators in the engine cooling circuit offers greater power density in a smaller package space when compared with electric actuators. In this paper, a comprehensive nonlinear backstepping robust control technique is developed to regulate the engine coolant temperature by controlling a hydraulic coolant pump and radiator fan. An experimental test bench has been assembled to investigate the hydraulic automotive thermal system performance. Representative numerical and experimental results are presented and discussed. Overall, the …

Reviewing Existing Knowledge Prior To Conducting Animal Studies, Andrew Knight

Experimentation Collection

Highly polarised viewpoints about animal experimentation have often prevented agreement. However, important common ground between advocates and opponents was demonstrated within a discussion forum hosted at www.research-methodology.org.uk in July–August 2008, by the independent charity, SABRE Research UK. Agreement existed that many animal studies have methodological flaws — such as inappropriate sample sizes, lack of randomised treatments, and unblinded outcome assessments — that may introduce bias and limit statistical validity. There was also agreement that systematic reviews of the human utility of animal models yield the highest quality of evidence, as their reliance on methodical and impartial methods to select significant …

Increasing Our Compassion Footprint: The Animals’ Manifesto, Marc Bekoff

Human and Animal Bonding Collection

Our relationships with animals are wide-ranging. When people tell me that they love animals and then harm or kill them I tell them I’m glad they don’t love me. Many individuals, including scientists, ignore their responsibility when they interact with animals and fail to recognize that doing something in the name of science, which usually means in the name of humans, is not an adequate reason for intentionally causing suffering, pain, or death. “Good welfare” usually is not “good enough.” Existing regulations allow animals to be treated in regrettable ways that demean us as a species. Compassion is the key …

Developmental Toxicity Testing: Protecting Future Generations?, Jarrod Bailey

Experimentation Collection

A recent editorial is discussed, which implied that animal-based developmental and reproductive toxicology tests will continue to be crucial, that the thalidomide disaster could have been prevented by more animal testing, and that tests on juvenile animals would help to protect children (as developing adults) from the adverse effects of pharmaceuticals. It is argued that animal tests in these scientific areas do not provide reliable data that are predictive for human responses and, even if they did, the tests are too expensive and time-consuming for application to the very large number of substances that need to be tested. It is …

Faecal-Centric Approaches To Wildlife Ecology And Conservation; Methods, Data And Ethics, C. T. Darimont, T. E. Reimchen, H. M. Bryan, P. C. Paquet

Ethics and Conservation Biology Collection

Abundant and commonly encountered in the field, wildlife faeces have long attracted scientists. Recent advances in molecular techniques, however, especially when coupled with creative study designs, can now yield a great variety of high quality data. Herein, we review the opportunities and challenges of faecal-centric approaches to address ecological and conservation questions using wolves of coastal British Columbia, Canada, as a case system. We begin by discussing methodological considerations, which should have broad applicability to any wildlife study system. We then summarize the extensive and unique variety of data that has emerged from our ‘facts from faeces’ approach with wolves, …

Understanding The Human Aspects Of Animal Hoarding, Amanda I. Reinisch

Passive Cruelty to Animals Collection

The Hoarding of Animals Research Consortium reviewed the case records of 71 incidents from across the United States and Canada to determine what characterizes a typical animal hoarding case (5). Of the cases reviewed, 83% involved women (71% involved individuals, who were widowed, divorced, or single); 53% of the animal hoarding residences were home to other individuals including children (5%), elderly dependents and disabled people (21%). Often essential utilities and major appliances such as showers, heaters, stoves, toilets, and sinks were not functional. Residential home interiors were usually unsanitary, 93%; 70% had fire hazards; and 16% of residences involved in …

Utilizing Quantum Dots To Enhance Solar Spectrum Conversion Efficiencies For Photovoltaics, Richard N. Savage, Hans Mayer, Matthew Lewis, Dan M. Marrujo

Materials Engineering

Silicon-based photovoltaics typically convert less than 30% of the solar spectrum into usable electric power. This study explores the utilization of CdSe based quantum dots as spectral converters that absorb the under utilized UV portion of the solar spectrum and fluoresce at wavelengths near the band-gap of silicon-based solar cells. A flexible 1 mm thick thin-film structure that contains an array of microfluidic channels is designed and fabricated in polydimethylsiloxane (PDMS) using soft-lithographic techniques. The channels are approximately 85 microns wide by 37 microns tall and are filled with a solution containing the quantum dots. The thin-film structure can easily …

Dispersal Of The Hudson River Plume In The New York Bight: Synthesis Of Observational And Numerical Studies During Latte, Robert J. Chant, John Wilkin, Weifeng Zhang, Byoung-Ju Choi, Eli Hunter, Renato Castelao, Scott Glenn, Joe Jurisa, Oscar Schofield, Robert Houghton, Josh Kohut, Thomas K. Frazer, Mark A. Moline

Biological Sciences

Observations and modeling during the Lagrangian Transport and Transformation Experiment (LaTTE) characterized the variability of the Hudson River discharge and identified several freshwater transport pathways that lead to cross-shelf mixing of the Hudson plume. The plume’s variability is comprised of several different outflow configurations that are related to wind forcing, river discharge, and shelf circulation. The modes are characterized by coastal current formation and unsteady bulge recirculation. Coastal currents are favored during low-discharge conditions and downwelling winds, and represent a rapid downshelf transport pathway. Bulge formation is favored during high-discharge conditions and upwelling winds. The bulge is characterized by clockwise …

Direct Extraction Of Normal Mapped Meshes From Volume Data, Mark Barry, Zoë J. Wood

Computer Science and Software Engineering

We describe a method of directly extracting a simplified contour surface along with detailed normal maps from volume data in one fast and integrated process. A robust dual contouring algorithm is used for efficiently extracting a high-quality "crack-free" simplified surface from volume data. As each polygon is generated, the normal map is simultaneously generated. An underlying octree data structure reduces the search space required for high to low resolution surface normal mapping. The process quickly yields simplified meshes fitted with normal maps that accurately resemble their complex equivalents.

The Structure Of The Gospel Of Mark: Revisiting The Implications Of Repetition And Characterization, Gregory Michael

Master of Sacred Theology Thesis

The search for a distinctive and coherent structure to the Gospel of Mark has long been a challenge for scholarship. While denying redaction and narrative criticism's slavish adherence to their methodology, this thesis utilizes repetition and characterization to assess the matter of Markan structure. Key points of repetition addressed within the text are repetition of words and phrases, forms, and thematic items. The discussion of words and phrases highlight: θάλασσα, πάλιν, εἰς π̍εραν, ἐν τ̂ηὁσ̂ω, and Jewish leaders. The forms addressed are call narratives, exorcisms, and passion predictions. The thesis presents six key repeated thematic elements: geopolitical locations, the senses …

Teen Pregnancy Prevention Programs: A Systematic Review Of Effects On Pregnancy Rates, Lorry E. Staufer

Regis University Student Publications (comprehensive collection)

Teen pregnancy is responsible for numerous negative outcomes for adolescent mothers, their offspring, and society. Myriad programs exist to address this problem; however, many programs administered do not monitor pregnancy rates. A systematic review was performed to assess programs that use pregnancy rates as an outcome measure. For primary prevention programs, components that address life skills and provide contraception information were found to be the most effective. For secondary prevention programs, successful programs provided immediate access to contraceptives.

The Nursing Shortage: A Fresh Perspective, Mary K. Wallenburg

Regis University Student Publications (comprehensive collection)

The current nursing shortage in the United States has the potential to become a major public health crisis (US Department, 2004). In recent years, a trend has developed that demonstrates a lack of interest on the part of young adults aged fifteen to eighteen years old towards nursing careers (Hoke, 2006). This research examines the attitudes and perceptions of young people, aged fifteen to eighteen years old; towards the field of nursing. The Methodology used to answer the research question was a survey tool developed by the author. The survey was created using the survey development site, Zoomerang©. Following IRB …

Individuals And Populations: How Biology's Theory And Data Have Interfered With The Integration Of Development And Evolution, David S. Moore

Pitzer Faculty Publications and Research

Research programs in quantitative behavior genetics and evolutionary psychology have contributed to the widespread belief that some psychological characteristics can be “inherited” via genetic mechanisms. In fact, molecular and developmental biologists have concluded that while genetic factors contribute to the development of all of our traits, non-genetic factors always do too, and in ways that make them no less important than genetic factors. This insight demands a reworking of the Modern Evolutionary Synthesis, a theory that defined evolution as a process involving changes in the frequencies of genes in populations, and that envisioned no role for experiential factors now known …

Pugnacité Et Pouvoir: La Représentation Des Femmes Dans Les Fi Lms D’Ousmane Sembène, Sheila Petty

Présence Francophone: Revue internationale de langue et de littérature

As a pioneer of African fi lmmaking, Ousmane Sembène has demonstrated a remarkable dedication to exploring the importance of women in African society. From the struggle against colonial oppression by Diouana in La Noire de… (1966) at the beginning of his career, to the character of Kiné and her struggle to build a life for her children in postcolonial Senegal in Faat Kiné (2000), Sembène has portrayed African women as agents of change and courage in their societies. This essay explores women’s representations in two fi lms from Sembène’s oeuvre, including Black Girl (1966) and Faat Kine (2000). Using narrative …
