Occurrence Of Male-Specific Bacteriophage In Feral And Domestic Animal Wastes, Human Feces, And Human-Associated Wastewaters, Kevin R. Calci, William Burkhardt Iii, William D. Watkins, Scott R. Rippey

Past Departments Faculty Publications (CELS)

Male-specific bacteriophage (MSB) densities were determined in animal and human fecal wastes to assess their potential impact on aquatic environments. Fecal samples (1,031) from cattle, chickens, dairy cows, dogs, ducks, geese, goats, hogs, horses, seagulls, sheep, and humans as well as 64 sewerage samples were examined for MSB. All animal species were found to harbor MSB, although the great majority excreted these viruses at very low levels. The results from this study demonstrate that in areas affected by both human and animal wastes, wastewater treatment plants are the principal contributors of MSB to fresh, estuarine, and marine waters.

Molecular Cloning And Sequencing Of Three Granulocytic Ehrlichia Genes Encoding High-Molecular-Weight Immunoreactive Proteins, James R. Storey, Linda A. Doros-Richert, Cindy Gingrich-Baker, Kenneth Munroe, Thomas N. Mather, Richard T. Coughlin, Gerald A. Beltz, Cheryl I. Murphy

Past Departments Faculty Publications (CELS)

Granulocytic Ehrlichia was isolated from canine blood obtained from animals challenged with field-collected Ixodes scapularis and propagated in HL60 cells. PCR primers specific for the 16S ribosomal DNA (rDNA) of the Ehrlichia genogroup comprising E. equi, E. phagocytophila, and the agent of human granulocytic ehrlichiosis (HGE) amplified DNA from extracts of these cells. Sequence analysis of this amplified DNA revealed that it is identical to the 16S rDNA sequence of the HGE agent. A genomic library was constructed with DNA from granulocyticEhrlichia and screened with pooled sera from tick-challenged, granulocytic Ehrlichia-infected dogs. Several clones were isolated …

Conservation And Variation In The Feeding Mechanism Of The Spiny Dogfish Squalus Acanthias, Cheryl D. Wilga, Philip J. Motta

Biological Sciences Faculty Publications

Changes in the feeding mechanism with feeding behavior were investigated using high-speed video and electromyography to examine the kinematics and motor pattern of prey capture, manipulation and transport in the spiny dogfish Squalus acanthias (Squalidae: Squaliformes). In this study, Squalus acanthias used both suction and ram behaviors to capture and manipulate prey, while only suction was used to transport prey. The basic kinematic feeding sequence observed in other aquatic-feeding lower vertebrates is conserved in the spiny dogfish. Prey capture, bite manipulation and suction transport events are characterized by a common pattern of head movements and motor activity, but are distinguishable …

Feeding Mechanism Of The Atlantic Guitarfish Rhinobatos Lentiginosus: Modulation Of Kinematic And Motor Activity, Cheryl D. Wilga, Philip J. Motta

Biological Sciences Faculty Publications

The kinematics and muscle activity pattern of the head and jaws during feeding in the Atlantic guitarfish Rhinobatos lentiginosus are described and quantified using high-speed video and electromyography to test hypotheses regarding the conservation and modulation of the feeding mechanism. Prey is captured by the guitarfish using suction. Suction capture, bite manipulation and suction transport behaviors in the guitarfish are similar to one another in the relative sequence of kinematic and motor activity, but can be distinguished from one another by variation in absolute muscle activation time, in the presence or absence of muscle activity and in the duration of …

Short Term Memory For Tempo In A Motor Timing Experiment, Sari Hooper

Open Access Master's Theses

This study investigated the role of short term memory in the motor reproduction of tempo. Seven undergraduate students participated in a finger-tapping experiment, in which retention intervals were incorporated into the classic continuation tapping paradigm. A two-way within-subjects design was employed, where subjects listen to and then attempt to reproduce a set tempo at 25 sub-second levels after retention intervals of 5 or 25 seconds. Musical Instrument Digital Interface (MIDI) software (Collyer, Boatright-Horowitz, & Hooper, 1997) was used to present stimulus tempos and record subjects tapping. Analyses of the inter-response intervals (IRls) indicated an effect of retention interval on the …

Developing A Theoretical And Empirical Ethnocultural Model Toward Predicting Crying Behavior In White College Women, Brian L. Ragsdale

Open Access Master's Theses

Self reported crying behavior in White college women along with ethnocultural variables which may influence their crying behavior was examined. Another focus of the study was to begin the development of an ethnocultural survey of crying behavior. Questions concerning socioeconomic status, religiosity/ spirituality, interpersonal experiences, family members feeling about crying behavior, perceptions of same race and other race crying, White Racial Identity Attitude (Helms, 1990) and the East/ West Questionnaire (Gilgen & Cho, 1979) were used as ethnocultural variables.

One hundred sixteen White women completed the survey during the first administration and sixty three of them completed the survey during …

Isolation Of The Virulence Gene(S) In The New, Live, Oral Vaccine Candidate Salmonella Typhimurium Sr-11 Fad, James H. Allen

Open Access Master's Theses

A DNA fragment containing the defective virulence gene(s) in the live oral vaccine candidate Salmonella typhimurium SR-11 Fad was isolated. Genomic DNA fragments from the vaccine candidate, constructed by Tn10d::cam transposon mutagenesis, were probed with the 1.4 Kbp chloramphenicol resistance gene contained in Tn10d::cam and analyzed by Southern hybridization. Two of the fragments, an 8.0 Kbp Hind III fragment and a 4.5 Kbp Pst I fragment, were isolated, cloned into E. coli HB 101, and mapped. The Pst I fragment, containing approximately 2.9 Kbp of flanking genomic DNA, was subcloned into the sequencing vector pBluescript …

Land Use Regulation, Takings Legislation, And The Wise Use Movement In Six States, Ronald M. Wolanski

Open Access Master's Theses

This project is the culmination of several months of research and data analysis on the Wise Use movement and takings legislation in six states (Kansas, Maine, Mississippi, Montana, Oregon, and Rhode Island). The aim of the research was to determine the relationship, if any, between the strength of environmental and land use regulation in the states and the prevalence of takings legislation. With a better understanding of the relationship of these factors, legislators, regulators, and planners will be better able address the concerns of constituents. My hypothesis was that the prevalence and strength of takings or property rights legislation is …

Lidocaine Metabolism In Endotoxin Induced Sepsis, Judah Boulet

Open Access Master's Theses

Septic shock is the body's inflammatory response to an infection, and is usually associated with gram negative bacteria. It is characterized by hypotension and hypoperfusion, despite adequate fluid resuscitation, and can lead to multiple organ failure. At these advanced stages there is a high morbidity and mortality rate associated with it. One mediator of this inflammatory response is a lipopolysaccharide (LPS), or endotoxin, found in the gram negative bacterial cell wall.

Besides having effects on the body as a whole, there are many cellular processes affected by endotoxin. In the body, there is a family of enzymes, the cytochrome P450 …

Relationship Between Attachment And Out-Of-Home Placements In Emotionally And Behaviorally Disordered Male Adolescents, Gail M. Curran

Open Access Master's Theses

Since its inception, Bowlby's attachment theory has guided research in the area of attachment. A body of literature supports the conclusion that when attachment needs are not met in the first year of life, serious deficits and problems can occur. The present study adds to the existing literature by examining attachment in adolescents, an age group not frequently researched. Specifically, this study examines the relationship between attachment and multiple out-of-home placements for adolescent males living in a residential treatment facility.

In order to understand the characteristics of youth living in a residential treatment facility, an archival search was completed to …

Logiccity: On-Line Digital Logic Simulator, Jihad Z. Almahayni

Open Access Master's Theses

A primary challenge for science educators is to develop ways to help students understand new ideas that cannot be directly observed. The application of computer simulations is one method instructors may use to address the problem of teaching for conceptual understanding. The use of computer simulations for science teaching is increasing steadily because simulations provide students with the opportunity to witness or "perform" experiments that might otherwise be too expensive, too time consuming, or too dangerous for them to do in the lab. Simulation, in general, is a very effective way for both a student and a professional to visualize …

Response Of Primary Producers To Nutrient Enrichment In A Shallow Estuary, Eleanor H. Kinney, Charles T. Roman

Graduate School of Oceanography Faculty Publications

Shallow coastal systems worldwide are exhibiting increased algal growth in response to nutrient enrichment. This study evaluates primary production patterns in an estuarine system (Bass Harbor Marsh, ME, USA) receiving low levels of anthropogenic nitrogen. Biomass, areal coverage and in situ oxygen production of green macroalgae, Ruppia maritima, and phytoplankton were measured over a growing season to determine net ecosystem production. Macroalgae and R. maritima exhibited seasonal biomass curves with early summer peaks; however, peak biomass of macroalgae [150 g dry weight (wt) m^-2] was substantially greater than R. maritima (33 g dry wt m^-2). …

Effects Of Zooplankton Size And Concentration And Light Intensity On The Feeding Behavior Of Atlantic Mackerel Scomber Scombrus, William K. Macy, Sandra J. Sutherland, Edward G. Durbin

Graduate School of Oceanography Faculty Publications

Atlantic mackerel Scomber scombrus had low clearance rates when fed older stage copepodites of the copepod Calanus finmarchicus at high concentrations and high clearance rates at low concentrations. These rates were consistent with filter feeding at high concentrations and particulate feeding at low concentrations. Intermediate and small copepods presented together at high concentrations were cleared at lower rates than the large C. finmarchicus, suggesting lower filtration efficiencies. Intermediate and small copepods were presented over a range of light intensities (8.2 x 10^-8 to 1.6 x 10⁰ µE m^-2 s^-1). Feeding rate did not change …

Rna:Dna Ratios As Indicators Of Nutritional Condition In The Copepod Calanus Finmarchicus, M. Wagner, Edward G. Durbin, L. Buckley

Graduate School of Oceanography Faculty Publications

As part of an investigation of ribonucleic acid (RNA) content as an index of growth and nutritional condition of zooplankton in the field, we describe here a method for measuring RNA and DNA in individuals, Stage N5 through adult, of the copepod Calanus finmarchicus. We used the technique to compare total RNA and DNA content and RNA:DNA ratios of C. finmarchicus copepodite stages cultured at different food densities. Copepods reared at growth-limiting phytoplankton concentrations (25 µg carbon l^-1) were smaller, had lower RNA:DNA ratios, and contained less total RNA and DNA than did copepods reared in excess …
