Gravity-Driven Thin Liquid Films With Insoluble Surfactant: Smooth Traveling Waves, Rachel Levy, Michael Shearer, Thomas P. Witelski

All HMC Faculty Publications and Research

The flow of a thin layer of fluid down an inclined plane is modified by the presence of insoluble surfactant. For any finite surfactant mass, traveling waves are constructed for a system of lubrication equations describing the evolution of the free-surface fluid height and the surfactant concentration. The one-parameter family of solutions is investigated using perturbation theory with three small parameters: the coefficient of surface tension, the surfactant diffusivity, and the coefficient of the gravity-driven diffusive spreading of the fluid. When all three parameters are zero, the nonlinear PDE system is hyperbolic/degenerateparabolic, and admits traveling wave solutions in which the …

An Integrated Social Actor And Service Oriented Architecture (Soa) Approach For Improved Electronic Health Record (Ehr) Privacy And Confidentiality In The Us National Healthcare Information Network (Nhin), Gondy Leroy, Elliot Sloane, Steven Sheetz

CGU Faculty Publications and Research

The emerging US National Healthcare Information Network (NHIN) will improve healthcare’s efficacy, efficiency, and safety. The first-generation NHIN being developed has numerous advantages and limitations. One of the most difficult aspects of today’s NHIN is ensuring privacy and confidentiality for personal health data, because family and caregivers have multiple complex legal relationships to a patient. A Social Actor framework is suggested to organize and manage these legal roles, but the Social Actor framework would be very difficult to implement in today’s NHIN. Social Actor Security Management could, however, be effectively implemented using Service Oriented Architectures (SOAs), which are rapidly becoming …

Diatom Species Composition And Ecology Of The Animas River Watershed, Colorado, Usa, Gerald V. Sgro, John B. Poole, Jeffrey R. Johansen

Biology

The diatom flora of selected sites in the Animas River Watershed, San Juan County, Colorado, was studied. Eighty diatom taxa were identified from 10 sites: 8 sites on the Animas River and 1 site each on the Cement and Cascade tributaries. The sample diatom abundance was dominated by Achnanthidium minutissimum, Encyonema silesiacum, Aulacoseira distans, Hannaea arcus, and Diatoma mesodon. The presence of teratologic specimens of Fragilaria and Achnanthidium in the samples indicated the possibility of metals contamination. Diatom diversity was low and Lange-Bertalot pollution index scores indicated little organic pollution evidenced from diatom composition. There was evidence that diatom composition …

Fisheries Research Report No. 160 - Development Of Biodiversity And Habitat Monitoring Systems For Key Trawl Fisheries In Western Australia., Mervi Kangas, S. Morrison, P. Unsworth, Eva K M Lai, I. Wright, Adrian W. Thomson

Fisheries Research Reports

Final FRDC report - Project 2002/038

The need for this project was identified through the ESD Risk Assessment workshops held for the Shark Bay and Exmouth Gulf trawl fisheries in May and October 2001. Bycatch issues in the Shark Bay and Exmouth fisheries were identified as a moderate risk through an Ecological Risk Assessment workshop. A better understanding of the faunal composition and habitat preferences of bycatch species in both trawled and untrawled areas has assisted in determining the level of risk to bycatch species. The project provided baseline data on biodiversity and variability of trawl bycatch on and off …

Video On The Semantic Sensor Web, Cory Andrew Henson, Amit P. Sheth, Prateek Jain, Josh Pschorr, Terry Rapoch

Kno.e.sis Publications

Millions of sensors around the globe currently collect avalanches of data about our world. The rapid development and deployment of sensor technology is intensifying the existing problem of too much data and not enough knowledge. With a view to alleviating this glut, we propose that sensor data, especially video sensor data, can be annotated with semantic metadata to provide contextual information about videos on the Web. In particular, we present an approach to annotating video sensor data with spatial, temporal, and thematic semantic metadata. This technique builds on current standardization efforts within the W3C and Open Geospatial Consortium (OGC) and …

The Environmental Factors Regulating The Distribution Of Crayfish In The Upper Green River Basin Kentucky, Usa, Eva Ngulo

Masters Theses & Specialist Projects

Despite the importance of crayfish in aquatic systems there are major issues threatening their conservation, including invasive species, habitat alterations, and species with small distributions or have limited geographical ranges. There is limited information regarding native range, habitat requirements, life histories and biological interactions between crayfish species. In order to examine the relationship between lotic crayfish assemblages and environmental variables at both the watershed and reach scales, data were collected from 46 stream segments in the Upper Green River Basin of Kentucky, U.S.A. An independent sample t-test compared crayfish densities between segments with gravel - small cobble, and large cobble …

The Effects Of Human/Wildlife Conflict On The Potential For Community-Based Ecotourism In The Kasigau Region Of Southeast Kenya, Natalie Mountjoy

Masters Theses & Specialist Projects

Many believe community-based ecotourism (CBE) can assist in conservation efforts and community development; however, little research has been done to assess the potential of CBE in a specific region. As part of a large, long-term, international research project, I define three problematic areas that may impede successful CBE efforts in the Kasigau location of southeast Kenya: bushmeat utilization, community attitudes and wildlife abundance. Samples of meat purchased from butcheries and meat markets are identified to species using molecular analysis, community attitudes are ascertained via written social surveys and transect sampling methods are used to determine the relative abundance and diversity …

Auditory Hair Cell Regeneration And Gene Expression In Noise-Exposed Zebrafish (Danio Rerio), Julie Schuck

Masters Theses & Specialist Projects

Fishes are capable of regenerating sensory hair cells in the inner ear after exposure to excessive noise. However, a time course of auditory hair cell regeneration has not been characterized for zebrafish, nor has gene expression following noise exposure. To establish a time course of hair cell regeneration, adult zebrafish were exposed to a 100 Hz pure tone at 179 dB re 1 |u.Pa RMS for 36 hours, and then allowed to recover for 0 to 14 days before morphological analysis. Hair cell loss and recovery were determined using phalloidin and DAPI labeling to visualize hair cell bundles and nuclei, …

Low Back Pain Among College Athletes - A Survey Of Basketball Players, Swimmers, Track And Field Athletes And Nonathletic Controls, Nicholas Bacon

Masters Theses & Specialist Projects

Study Design. Cross-sectional survey among athletes competing at the collegiate level in basketball, swimming, and track and field, as well as a matched nonathletic control group. Objective. To compare the prevalence of low back pain between sports: basketball, swimming, and track and field, as well as nonathletic control group. Summary of Background Data. With conflicting reports, it is not clear whether athletes are at higher risk for low back pain when compared to nonathletic counterparts. Some literature has found that low back pain was less common in former elite athletes when compared to nonathletes; however, much of the literature supports …

An Examination Of The Role Of Anxiety And Obsessive-Compulsive Features In Muscle Dysmorphia Symptomatology, Christopher Chandler

Masters Theses & Specialist Projects

Although Muscle Dsymorphia (MD) has received more attention in recent years, it still lacks an official classification. The current study incorporates trait anxiety and obsessive-compulsive features into an etiological model of MD in the hopes of establishing them as reliable predictors of such MD symptomatology as drive for muscularity, social physique anxiety, and negative body attitude (self). This model was based upon previous research that has linked trait anxiety and obsessive-compulsive features to eating disorders (ED). In this model, it was predicted that trait anxiety and obsessive-compulsive features would predict overall MD symptomatology, drive for muscularity, social physique anxiety, and …

A Novel Zinc-Binding Domain Is Essential For Formation Of The Functional Junin Virus Envelope Glycoprotein Complex, Joanne York, Jack H. Nunberg

Biological Sciences Faculty Publications

The envelope glycoprotein of the Junin arenavirus (GP-C) mediates entry into target cells through a pH-dependent membrane fusion mechanism. Unlike other class I viral fusion proteins, the mature GP-C complex retains a cleaved, 58-amino-acid signal peptide (SSP) as an essential subunit, required both for trafficking of GP-C to the cell surface and for the activation of membrane fusion. SSP has been shown to associate noncovalently in GP-C via the cytoplasmic domain (CTD) of the transmembrane fusion subunit G2. In this report we investigate the molecular basis for this intersubunit interaction. We identify an invariant series of six cysteine and histidine …

Dietary Canola Oil Suppressed Growth Of Implanted Mda-Mb 231 Human Breast Tumors In Nude Mice, W. Elaine Hardman

Biochemistry and Microbiology

Long chain omega 3 (n-3) fatty acids, eicosapentaenoic (EPA) and/or docosahexaenoic acid (DHA), have been shown to suppress growth of most cancer cells. In vivo, alpha linolenic acid (ALA, 18:3n-3) can be converted to EPA or DHA. We hypothesized that substituting canola oil (10% ALA) for the corn oil (1% ALA) in the diet of cancer bearing mice would slow tumor growth by increasing n-3 fatty acids in the diet. Sixty nude mice received MDA-MB 231 human breast cancer cells and were fed a diet containing 8% w/w corn oil until the mean tumor volume was 60 mm ³ . …

Phylogenetic Relationships Within The Centothecoideae + Panicoideae Clade (Poaceae) Based On Ndhf And Rpl16 Intron Sequences And Structural Data, J. Gabriel Sánchez-Ken, Lynn G. Clark

Aliso: A Journal of Systematic and Floristic Botany

The PACCAD clade (Panicoideae, Arundinoideae, Chloridoideae, Centothecoideae, Aristidoideae, Danthonioideae) is well supported in all recent studies of Poaceae. However, phylogenetic relationships within the clade are still unresolved, although several branches are strongly supported. In this study, we focus on the phylogeny of the Centothecoideae + Panicoideae clade, one of the major lineages within the PACCAD clade, and one of the most diverse in the family. Two previously unsampled tribes, Isachneae and Steyermarkochloeae, are included, as are additional taxa of Centothecoideae. Phylogenetic analyses of plastid genome sequences (ndhF gene and rpl16 intron) and structural data show increased support …

Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington

Aliso: A Journal of Systematic and Floristic Botany

Panicoideae (Poaceae) in the New World comprise 107 genera (86 native) and 1357 species (1248 native). As circumscribed herein, Panicoideae include eight tribes: Andropogoneae, Arundinelleae, Centotheceae, Gynerieae, Isachneae, Paniceae, Steyermarkochloeae, and Thysanolaeneae. The two major tribes are Andropogoneae with 230 species (16.95% of all New World panicoids), and Paniceae with 1082 species (79.73%). Andropogoneae are divided into nine subtribes (Andropogoninae, Anthistiriinae, Coicinae, Germainiinae, Ischaeminae, Rottboelliinae, Saccharinae, Sorghinae, and Tripsacinae), while Paniceae are divided into seven subtribes (Arthropogoninae, Cenchrinae, Digitariinae, Melinidinae, Panicinae, Paspalinae, and Setariinae). Brazil is the center of diversity of New World panicoids with 741 species (54.6% of all …

Inflorescence Architecture And Floral Morphology Of Aratitiyopea Lopezii (Xyridaceae), Lisa M. Campbell, Dennis Wm. Stevenson

Aliso: A Journal of Systematic and Floristic Botany

Aratitiyopea lopezii is a robust perennial species of Xyridaceae from seasonally saturated, mid- to high-elevation, sandstone and granite sites in northern South America. The species lacks the scapose inflorescence characteristic of Xyridaceae and, having the gestalt of a rhizomatous bromeliad, it is seemingly aberrant in the family. However, closer examination confirms features consistent with the family and the previously noted morphological similarities to Orectanthe. Details of inflorescence structure and floral morphology are presented and compared to other genera of Xyridaceae.

Systematics Of The Tribe Stipeae (Gramineae) Using Molecular Data, Surrey Jacobs, Randall Bayer, Joy Everett, Mirta Arriaga, Mary Barkworth, Alexandru Sabin-Badereau, Amelia Torres, Francisco Vázquez, Neil Bagnall

Aliso: A Journal of Systematic and Floristic Botany

Internal transcribed spacer (ITS) sequences have been determined for a wide range of stipoid grasses (Poaceae, Pooideae, Stipeae). Nardus was confirmed as the most appropriate outgroup. Anisopogon is consistently included among the stipoid genera. Lithachne and Oryza form a clade and are clearly not close to Stipeae, and there is no support for including Brachyelytrum within Stipeae. Ampelodesmos and Diarrhena do appear among the core taxa in some analyses, but their positions are unstable and the evidence for retaining them is limited. So far there is inadequate support for rejecting them from Stipeae, so they should be included in any …

Global Asymptotic Behavior Of Yn+1 = (Pyn + Yn-1)/(R + Qyn + Yn-1), A. Brett, M. R.S. Kulenović

Mathematics Faculty Publications

We investigate the global stability character of the equilibrium points and the period-two solutions of yn+1 = (pyn + yn-1)/(r + qyn + yn-1), n = 0, 1,..., with positive parameters and nonnegative initial conditions. We show that every solution of the equation in the title converges to either the zero equilibrium, the positive equilibrium, or the period-two solution, for all values of parameters outside of a specific set defined in the paper. In the case when the equilibrium points and period-two solution coexist, we give a precise description of the basins of attraction of all points. Our results give …

Western Gray Whales Off Sakhalin Island, Russia: A Joint Russia-U.S. Scientific Investigation July-September 2007, David W. Weller, Amanda L. Bradford, Aimée R. Lang, Hyun Woo Kim, Maxim Sidorenko, Grigory A. Tsidulko, Alexander M. Burdin, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

A collaborative Russia-U.S. research program on western gray whales (Eschrichtius robustus) summering off northeastern Sakhalin Island, Russia, has been ongoing since 1995 and has produced important new information on the present day conservation status of this critically endangered population. This interim report reviews preliminary findings from 2007 research activities and combines such with data from previous years, in some cases ranging back to 1994. Photo-identification research conducted off Sakhalin Island in 2007 resulted in the identification of 83 whales, including nine calves and two previously unidentified non-calves. When combined with data from 1994-2006, a catalog of 169 photo-identified …

Restoring Wildlife Habitat On Rat Island: Environmental Assessment

United States Fish and Wildlife Service: Publications

Restoration of natural ecosystem function on Rat Island promises to re-establish native seabirds and other native species, thus returning this wilderness island to a healthy natural community. This restoration cannot occur until the island is cleared of the invasive non-native rats that now dominate the living community.

Introduced non-native species are a leading cause of extinctions in island communities worldwide. Increasingly, land managers are removing introduced species to aid in the restoration of native ecosystems. Rats are responsible for 40-60% of all recorded bird and reptile extinctions worldwide. Given their widespread successful colonization on islands and the resulting impact to …

Fda Drug Approvals: Time Is Money!, Andreas Sturm, Michael J. Dowling, Klaus Röder

The Journal of Entrepreneurial Finance

We investigated the stock price behavior of public pharmaceutical and biotechnology companies upon approval of a drug by the Food and Drug Administration (FDA). Using event study methodology, we examine the reaction caused by the approval, seperating it from the asset price movements caused by other factors such as market and industry effects. The results are then used to validate the model developed in this article as an alternative to the explanations given by Sharma and Lacey (2004). The results of this study support the Efficient Market Hypothesis, i.e. that the market reacts to the new information quickly and clearly.

How To Prevent Perioperative Myocardial Injury: The Conundrum Continues, Jian-Zhong Sun, David Maguire

Department of Anesthesiology Faculty Papers

BACKGROUND: Perioperative myocardial injury (PMI) remains a major cause of perioperative morbidity and mortality but clinical strategies to prevent PMI are still uncertain.

METHODS AND RESULTS: We comprehensively searched PubMed for major research articles concerning clinical strategies to prevent PMI. The key findings are as follows: (1) the American College of Cardiology/American Heart Association guideline update for perioperative cardiovascular evaluation for noncardiac surgery is very useful to stratify cardiac risk preoperatively; (2) cardiac troponin has emerged as a biomarker to diagnose postoperative PMI and to predict clinical outcomes; (3) coronary revascularization before noncardiac surgery probably would provide cardiac protection in …

Markov Processes In Single Molecule Fluorescence, David Talaga

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

This article examines the current status of Markov processes in single molecule fluorescence. For molecular dynamics to be described by a Markov process, the Markov process must include all states involved in the dynamics and the first-passage time (FPT) distributions out of those states must be describable by a simple exponential law. The observation of non-exponential FPT distributions or other evidence of non-Markovian dynamics is common in single molecule studies and offers an opportunity to expand the Markov model to include new dynamics or states that improve understanding of the system.
