Frequency Of Natural Hybridization Between Saugers And Walleyes In The Peoria Pool Of The Illinois River, As Determined By Morphological And Electrophoretic Criteria, Neil Billington, Ronald C. Brooks, Roy C. Heidinger

Publications

External morphological characteristics and protein electrophoresis at two diagnostic loci were used to determine the proportion of 704 Stizostedion samples collected from the Peoria Pool of the Illinois River during March 1995 that were saugers S. canadense, walleyes S. vitreum, or their hybrids. Morphological analyses indicated that 616 (87.5%) fish were saugers, 58 (8.2%) were walleyes, and 30 (4.3%) were hybrids; electrophoretic analyses indicated that 625 (88.8%) fish were saugers, 50 (7.1%) were walleyes, and 29 (4.1%) were hybrids. Clear discrepancies between the morphological and electrophoretic analyses affected at least 43 (6.1%) fish. Only 2% of saugers were …

Teaching General Biology For Nonmajors Through Community Service Projects, Mary Wells Phillips

Higher Education

For many students, especially for the biology nonmajors, science is often one of the last courses they take before completing their degree. Often, these students enter my course with a previous "bad" experience from courses in high school or have developed anxieties regarding what science is all about. They are reluctant learners who frequently shy from questions and classroom discussions. Their own insecurities and presumed lack of knowledge frequently !eaves them floundering and confused. The message is, "I am here because I need 'x' number of science units before completing my degree."

Adaptation Of The Doubly Labeled Water Method For Subjects Consuming Isotopically Enriched Water, Randall J. Gretebeck, Dale A. Schoeller, Rick A. Socki, Janis Davis-Street, Everett K. Gibson, Leslie O. Schulz, Helen W. Lane

College of Nursing Faculty Research and Publications

The use of doubly labeled water (DLW) to measure energy expenditure is subject to error if the background abundance of the oxygen and hydrogen isotope tracers changes during the test period. This study evaluated the accuracy and precision of different methods by which such background isotope changes can be corrected, including a modified method that allows prediction of the baseline that would be achieved if subjects were to consume water from a given source indefinitely. Subjects in this study were eight women (4 test subjects and 4 control subjects) who consumed for 28 days water enriched to resemble drinking water …

Monte Carlo Simulation Of The Solid To Superliquid Phase Transition Of Langmuir Monolayers. Ii. Characteristics Of Phase Transition, M.D. Gibson, D.R. Swanson, Craig J. Eckhardt, Xiao Cheng Zeng

Craig J. Eckhardt Publications

The restricted-to-free rotator phase transition of fatty acid monolayers has been modeled using a potential which represents the amphiphiles as planar cross sections of fourfold symmetry. Using much larger system sizes than paper I [D. R. Swanson, R. J. Hardy, and C. J. Eckhardt, J. Chem. Phys. 99, 8194 (1993)], Monte Carlo simulations of the isobaric–isothermal ensemble of model systems with varied number of objects were undertaken to study the effect of system size on the characteristics and order of the phase transition. A peak in the specific heat vs temperature curve was observed near the transition. For each system …

Prenatal Cocaine Exposure And Mother–Infant Interaction: Implications For Occupational Therapy Intervention, Heather Miller-Kuhaneck

Occupational Therapy Faculty Publications

The literature from multiple disciplines on in utero cocaine exposure and mother–infant interaction and attachment was examined for possible relationships and implications for occupational therapists. Maternal cocaine use and neurobehavioral deficits in neonates prenatally exposed to cocaine may result in interactional difficulties between mother and infant. Knowledge of child development, sensory regulation, and infant cues will enable therapists to assist the mother in creating positive interactive experiences between herself and her child.

Organizational Configurations And Performance: A Meta-Analysis, David J. Ketchen Jr., James G. Combs, Craig J. Russell, Chris Shook, Michelle A. Dean, Janet Runge, Franz T. Lohrke, Stefanie E. Naumann, Dawn Ebe Haptonstahl, Robert Baker, Brendon Beckstein, Charles Handler, Heather Honig, Stephen Lamoureux

Faculty Publications

The link between organizational configurations and performance has become a central and somewhat controversial focus of research in the strategic management literature, We statistically aggregated results from 40 original tests of the configurations-performance relationship. In contrast to previous qualitative reviews, this meta-analysis demonstrated that an organization's performance is partially explained by its configuration. Tests of four potential moderators showed that organizations' configurations contributed more to performance explanation to the extent that studies used (1) broad definitions of configurations, (2) single-industry samples, and (3) longitudinal designs, Results highlight the need for programmatic research.

Analysis Of Gene Expression During Embryonic Development In Mulberry Silkworm Bombyx Mori, Amit Singh, K. P. Gopinathan

Biology Faculty Publications

We have developed a method for dechorionation and devitellinization of the silkworm eggs without damage, to facilitate the analysis of gene expression during embryonic development of Bombyx mori. Making use of antibodies available from heterologous systems, the spatio-temporal expression patterns of peroxidase and proliferating cell nuclear antigen have been directly visualized in whole mount embryos at various stages of development without the need for generating transformed ·lines carrying specific reporter constructs. The B. mori system, previously unamenable for such studies, could thus serve as an attractive model for molecular analysis of insect development.

Residual Strength Of Equine Bone Is Not Reduced By Intense Fatigue Loading: Implications For Stress Fracture, R. B. Martin, V. A. Gibson, S. M. Stover, J. C. Gibeling, L. V. Griffin

Biomedical Engineering

Fatigue or stress fractures are an important clinical problem in humans as well as racehorses. An important question in this context is, when a bone experiences. fa!igue damage ~uring e~treme use, how much is it weakened compared to its original state? Since there are very ltmtted data on thts quesuon and stress fractures are common in racehorses, we sought to determine the effect of fatigue loading on the monotonic l:trength of equine cortical bone. Beams were machined from the dorsal, medial and lateral cortices of the third metacarpal bones of six thoroughbred racehorses. Beams from left and right bones were …

The Underrepresentation Of Minorities In The Legal Profession: A Critical Race Theorist's Perspective, Alex M. Johnson Jr.

Michigan Law Review

Over the last four years, I have taught a course in Critical Race Theory at the University of Virginia School of Law three times. Although each course is different, given the interplay between the teacher and the students and the integration of new developments into the course, there has been one constant subject that the students and I address: Of what import is the development of Critical Race Theory for the legal profession and larger society? Can Critical Race Theory have a positive or any effect for those outside legal academia? This article represents an attempt to explore that question …

Study Of The Wear Of Dental Composites Using An Atomic Force Microscope, Dale E. Ewbank

Theses

This work presents a study of the wear of four dental composites (Concept, XRV, Maxxim, and Belleglass) which are in commercial use. The wear testing was performed using an Atomic Force Microscope (AFM). Several scanning techniques and various cantilevers were attempted. Finally use of a stainless steel cantilever with a tungsten bead attached resulted in quantifiable wear. AFM imaging in contact mode was used for evaluation of the wear tests. Wear rates are reported as volume per 100,000 scans. The AFM measured wear rates rank the tested composites from most to least wear as follows: Concept highest volume of wear …

Detecting The Abnormal: Machine Learning In Computer Security, Terran Lane, Carla E. Brodley

Department of Electrical and Computer Engineering Technical Reports

TINOpr oblems of importance in computer security are to I) detect the presence of an intruder masquerading as the valid user and 2) detect the perpetration of abusive actions on the part of an otherwise innocuous user. In this paper we present a machine learning approach to anomaly detection, desigined to handle these two problems. Our system learns a user profile for each user account and subsequently employs it to detect anomalous behavior in that account. Based on sequences of actions (UNIX commands) of the current user's input sti:earn, the system compares each fixed-length input sequence with a historical library …

Listeria Monocytogenes Scott A Transports Glucose By High-Affinity And Low-Affinity Glucose Transport Systems, Corinne Parker, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Listeria monocytogenes transported glucose by a high-affinity phosphoenolpyruvate-dependent phosphotransferase system and a low-affinity proton motive force-mediated system. The low-affinity system (K_m = 2.9 mM) was inhibited by 2-deoxyglucose and 6-deoxyglucose, whereas the high-affinity system (K_m= 0.11 mM) was inhibited by 2-deoxyglucose and mannose but not 6-deoxyglucose. Cells and vesicles artificially energized with valinomycin transported glucose or 2-deoxyglucose at rates greater than those of de-energized cells, indicating that a membrane potential could drive uptake by the low-affinity system.

Genetic Variability Among Maize Inbred Lines For Resistance To The High Plains Virus–Wheat Streak Mosaic Virus Complex, A. Marçon, S. M. Kaeppler, S. G. Jensen

Department of Plant Pathology: Faculty Publications

High plains virus (HPV) is a pathogen that causes a severe disease, especially in susceptible corn genotypes. The virus is transmitted by the eriophyid mite Aceria tosichella, which also transmits wheat streak mosaic virus (WSMV). This often results in a mixed infection by these two viruses. Genetic variability for resistance to the HPV exists among maize inbred lines but has not been characterized. The disease reaction of 30 maize inbred lines to the mixed infection and to WSMV alone was characterized in this study. Evaluation was based on symptom expression and virus titer (HPV and WSMV), as measured by …

Encapsidation Of Turnip Crinkle Virus Is Defined By A Specific Packaging Signal And Rna Size, Feng Qu, Thomas Jack Morris

Nebraska Center for Virology: Faculty Publications

A protoplast infection assay has been used to reliably examine the viral RNA encapsidation of turnip crinkle virus (TCV). Analysis of the encapsidation of various mutant viral RNAs revealed that a 186-nucleotide (nt) region at the 3’ end of the coat protein (CP) gene, with a bulged hairpin loop of 28 nt as its most essential element, was indispensable for TCV RNA encapsidation. When RNA fragments containing the 186-nt region were used to replace the CP gene of a different virus, tomato bushy stunt virus, the resulting chimeric viral RNAs were encapsidated into TCV virions. Furthermore, analysis of the encapsidated …

Phylogenetic Analysis Of Nematodes Of The Genus Pratylenchus Using Nuclear 26s Rdna, Luma Al-Banna, Valerie M. Williamson, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We used nucleotide sequences of the large subunit ribosomal genes (26S rDNA) to examine evolutionary relationships among species of the genus Pratylenchus (Order: Tylenchida, Family: Pratylenchidae), commonly known as root-lesion nematodes. Ten species of Pratylenchus were studied including, P. penetrans, P. crenatus, P. minyus, P. vulnus, P. thornei, P. musicale, P. coffeae, P. bexincisus, P. scribneri, and P. brachyurus. The species Hirschmanniella belli, Meloidogyne javanica, Heterorhabditis bacteriophora, Nacobbus eberruns, Radopholus similis, and Xiphinema index were used as outgroups. Based on parsimony analyses of approximately 307 …
