Cyanonews (Vol. 13, No. 1, July 1997), Jeff Elhai

CyanoNews

CyanoNews was a newsletter that served the cyanobacteriological community from 1985 to 2003, with content provided by readers (sort of a blog before there were blogs). The newsletter reported new findings from the lab, summaries of recent meetings (often provided by graduate students and post-docs entering the field), positions sought or available, life transitions, a compendium of recent cyanobacteria-related articles, and other items of interest to those who study cyanobacteria.

Diffusion Behavior Of Lipid Vesicles In Entangled Polymer Solutions, X. Cao, R. Bansil, D. Gantz, E.W. Moore, N. Niu, Nezam H. Afdhal

Internal Medicine Publications

ABSTRACT

Dynamic light scattering was used to follow the tracer diffusion of phospholipid/cholesterol vesicles in aqueous polyacrylamide solutions and compared with the diffusive behavior of polystyrene (PS) latex spheres of comparable diameters. Over the range of the matrix concentration examined (Cp = 0.1-10 mg/ml), the diffusivities of the PS spheres and the large multilamellar vesicles exhibited the Stokes-Einstein (SE) relation, while the diffusivity of the unilamellar vesicles did not follow the increase of the solution's viscosity caused by the presence of the matrix molecules. The difference between the diffusion behaviors of unilamellar vesicles and hard PS spheres of similar size …

Editor's Note, Faythe Tumer

Ethnic Studies Review

This issue of the Journal of the National Association of Ethnic Studies presents an interesting cross section of ethnic groups in the United States: Native American, Vietnamese, Latino, African American. Several of the articles involving these groups raise the persistent question of assimilation versus acculturation and where the health and welfare of the children of immigrants or the younger generation of immigrants lies. Shaw N. Gynan in "Hispanic Immigration and Spanish Maintenance as Indirect Measures of Ethnicity: Reality and Perceptions" has found that the newest generation of Latinos not only are more involved ethnically with their Spanish heritage than earlier …

An Examination Of Social Adaptation Processes Of Vietnamese Adolescents, Fayneese Miller, My Do, Jason Sperber

Ethnic Studies Review

The purpose of the study was to examine the factors that affect the ways in which Vietnamese youth feel about themselves and their "place" in society. More specifically, the purpose was to determine the relationship between sociocultural factors (L e. language proficiency, length of residence, socioeconomic class, ethnic identity, and cultural continuity) and such person-oriented variables as depression and alienation. Thrity-one college and fifteen high school students responded to a series of questions about themselves, family, relationships, personality, and achievement motivation. It was found that perceived problems with one's ethnic group, cultural continuity, and parental attitudes toward schooling significantly predicted …

Analysis Of Phosphorescence In Heterogeneous Systems Using Distributions Of Quencher Concentration, A.S. Golub, A.S. Popel, L. Zheng, R.N. Pittman

Physiology and Biophysics Publications and Presentations

ABSTRACT

A continuous distribution approach, instead of the traditional mono- and multiexponential analysis, for determining quencher concentration in a heterogeneous system has been developed. A mathematical model of phosphorescence decay inside a volume with homogeneous concentration of phosphor and heterogeneous concentration of quencher was formulated to obtain pulse-response fitting functions for four different distributions of quencher concentration: rectangular, normal (Gaussian), gamma, and multimodal. The analysis was applied to parameter estimates of a heterogeneous distribution of oxygen tension (P02) within a volume. Simulated phosphorescence decay data were randomly generated for different distributions and heterogeneity of PO2 inside the excitation/emission volume, consisting …

The Perception Of Non-Perception: Lessons For Art Education With Downcast Eyes (Part One: Trompe-L’Oeil And The Question Of Radical Evil), Jan Jagodzinski

Journal of Social Theory in Art Education

The Roman historian Pliny recounts a story that occurred during Periclean Athens. I will utilize this story, as a trope to undertake an interrogation of perception as it is commonly understood and currently practiced by art educators in schools. In order to deconstruct vision/blindness, or the perception/non-perception binary, I have examined the psychoanalytic paradigm of Jacques Lacan. His current interpreters provided the conceptual tools for such an undertaking. Given that the question of representation has become a key sign-post of postmodernism, art educators must conceptualize a trajectory for itself in the 21st century. Part One of such a trajectory questions …

Electrophysiological Effects Of Lysoplasmenylcholine On Rabbit Ventricular Myocytes, Ray Caldwell

Theses and Dissertations

Myocardial ischemia activates a phospholipase A2 that targets plasmalogen phospholipids and liberates 1-0-alkenyl-Iysoplasmenylcholine (LPLC) in preference to 1-0- acyl-Iysophosphatidylcholine (LPC). Although LPC is a pro arrhythmic ischemic metabolite, the effect of LPLC on cardiac electrophysiology is unknown. At the lowest doses investigated, LPLC induced spontaneous contractions in otherwise quiescent rabbit ventricular myocytes significantly faster than LPC. Spontaneous contractions developed with median times of 16.4 (n = 64), 27.4 (n = 36), and >60 min (n = 25) during exposure to 5, 2.5, and 1 JlM LPLC compared with 38.0 (n = 48) and >60 min (n = 29) for 5 …

The Seated Cleopatra In Nineteenth Century American Sculpture, Kelly J. Gotschalk

Theses and Dissertations

This thesis explores Cleopatra as presented in the work of three nineteenth century American sculptors: Thomas Ridgeway Gould, Edmonia Lewis and William Wetmore Story. It illuminates their work in the context of the nineteenth century and within the history of Cleopatra's image. Victorian opinions of Cleopatra's nature are exposed by examining the Egyptian Queen in essays and literature of the period, including works by Anna Jameson, Emily Dickinson, Charlotte Bronte, Nathaniel Hawthorne and Theophile Gautier. By studying the role of Cleopatra in these literary examples, the notion of some recent scholars of Cleopatra as a feminist symbol is dispelled and …

Toward The Universal, Jennifer Bracy

Theses and Dissertations

This creative project is concerned with archetypal forms expressed in art, design and communication, from Neolithic rock carvings and native American Indian petroglyphs to individual graphic languages that look to the 'primitives' like those of Joan Miro and Neville Brody. It is my belief that through the study of this diverse collection of graphic signs and archetypal forms, one can develop a system of signs that cross barriers of language and culture. A morphology, a collection of possibilities, derived from such archetypal forms, could provide designers with a foundation for the development and use of symbol signs and sign systems.

Estimation Of The Ld100p When P Is Small, Daniel Bettendorf

Theses and Dissertations

This thesis concerns the estimation of extreme quantiles on a dose-response curve. It focuses on the Robbins-Monro and up-and-down procedures. Simulation studies run in search of the LD15 and LD30 using a variety of methods suggest that the Robbins-Monro procedure is optimal in terms of Monte Carlo MSE and bias. The up-and-down procedure's performance differs in many cases only slightly from that of the Robbins-Monro process, therefore indicating its value as a practical alternative to the Robbins-Monro process for extreme-quantile estimation.

Comparison Of Epidural And Intravenous Fentanyl Patient-Controlled Analgesia After Cesarean Section Under Epidural Anesthesia With Chloroprocaine, Kim M. Larsen

Theses and Dissertations

This study compared two methods of postcesarean fentanyl patient- controlled analgesia (PCA). Fentanyl was administered intravenously (PCA_I) or epidurally (PCA_E) following cesarean section under epidural chloroprocaine anesthesia. Twenty-one ASA I and II parturients were randomly assigned to receive fentanyl PCA_I (n = 9) or PCA (n = 12). At surgical completion fentanyl 1.0 mcg/kg was given and the PCA initiated with a dose of 30 mcg, a lockout interval of 10 minutes, a maximum dose of 180 mcg/hr, and no basal rate. Data were collected over 24 hours including visual analog scale (VAS) pain scores, …

Contemporary Couple Enrichment: A Critical And Meta-Analytic Review Of Methodology, Terry L. Hight

Theses and Dissertations

The purpose of this study was to examine the effectiveness of contemporary couple enrichment using currently-accepted standards of meta-analytic research. Twenty-seven published studies that compared enrichment groups to control groups were included in the analyses. The overall mean effect size (0.32), post-treatment effect size (0.35), and follow-up effect size (0.35) for couple enrichment were heterogeneous, positive, and significantly different than 0. Mean effect sizes for both post-treatment and follow-up did not differ significantly, Moderator variables associated with program type, measure type, nature of dependent variable, quality of methodology, measure reactivity, measure specificity, and researcher allegiance significantly improved homogeneity across effect …

Tumor Immunity Following Adenovirus Mediated Herpes Simplex Thymidine Kinase Gene Transfer To Experimental Rat Gliomas, Maulik Raj Shah

Theses and Dissertations

Previous studies have determined adenovirus mediated herpes simplex thymidine kinase gene transfer (AV-TK) to be effective for the treatment of experimental gliomas. In this study we report three distinct phenomenon. First, animals with complete regression of subcutaneous tumors upon intratumoral injections of AV-TK with concomitant Ganciclovir® (GCV) administration developed tumor immunity. These animals had the ability to reject a subsequent inoculum of lethal doses of tumor cells. This tumor immunity was long standing and protective as far as 6 months from the time of initial tumor ablation. Of interest, adoptive transfer of splenocytes from AV-TK treated-tumor ablated animals to naive …

Race And Birthweight: The Influence Of Socio-Economic Status And Utilization Of Prenatal Care, Lena C. Frennborn

Theses and Dissertations

The purpose of this research was to determine how much of the variance in birthweight can be explained by socio-economic status and utilization of prenatal care in Blacks and Whites. Rather than defining race in genetic terms, race was understood here as a social construction. The methodological approach was an analysis of the National Survey of Family Growth Cycle IV, 1988. The first, singleton, live birth for each interviewed woman was included, resulting in a sample of 911 women, of whom 313 were Black women and 598 White women.

Consistent with previous research, Black mothers were twice as likely to …

Vcu Voice (1996-12-09)

VCU Voice, 1988-1998

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.
