Eimeria From Bats Of Bolivia: Two New Species From Vespertilionid Bats, Donald W. Duszynski, Damien T. Scott, Xiaomin Zhao

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Between 1985 and 1987, fecal samples were collected from 71 bats representing 14 species (Desmodontidae, Molossidae, Noctilionidae, Phyllostomidae, Vespertilionidae) from 8 localities in 3 states (Beni, Pando, Santa Cruz) in Bolivia, South America. Of these, 2 black myotid bats (Vespertilionidae), Myotis nigricans, and 1 tent-making bat (Phyllostomidae), Uroderma magnirostrum, had oocysts in their feces that represent undescribed species of Eimeria. The new species from M. nigricans (2/4, 50%) has sporulated oocysts that are subspheroidal, 18.9 × 16.9 (17-23 × 14-20) μm, without a micropyle; oocyst residuum of 6-8 spheroidal globules and 1 highly refractile polar granule are …

Aerodrome Bird Hazard Prevention: Case Study At John F. Kennedy International Airport, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

The collision of birds with aircraft is a serious problem at John F. Kennedy International Airport (JFKIA), New York. Gulls (Larus spp.) accounted for 86% of bird strikes (an aircraft striking >1 bird) from 1988-1990, averaging 260 strikes/year. Laughing Gulls (L. atricilla) are present from May- September in association with a protected nesting colony in Jamaica Bay National Wildlife Refuge adjacent to the airport. The colony increased from 15 nests in 1979 to 7,629 nests in 1990. During the 1970s and 1980s, JFKIA implemented various management activities to reduce gull strikes, including maintenance of tall grass, improved sanitation, drainage of …

The Relationship Of Job Congruence, Job Satisfaction, And Social Support On The Mental And Physical Health Of Sport Officials., Paul James Sundell

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this study was to expand the research associated with the effects of stress on sport officials. The study examined the impact that job congruence, job satisfaction, and social support may have on health among sport officials by testing a mediational model of relationships in a system developed through theory and previous research. Data were collected from 125 sport officials sanctioned to officiate in the state of Iowa. They responded to the Vocational Preference Inventory, Minnesota Satisfaction Questionnaire, Social Support Questionnaire, Symptom Checklist-90R, and a demographic data sheet. Statistically significant correlations were found between job congruence and positive …

Brownfields Policies For Sustainable Cities, Joel B. Eisen

Law Faculty Publications

My analysis begins in Part I with a short summary of brownfields law and policy, and a description of our current understanding of "sustainable development." There is no hard and fast definition of the term, but it is increasingly more clear that a body of sustainable development "law" will take shape as the product of a host of decisions made now and in the near future. The optimal way to ensure that brownfields programs mesh with this body of law-whatever it turns out to be-is to incorporate basic norms of sustainable development about which there is widespread agreement. Those agreed-upon …

The Concept Of Familiarity And Pest Resistant Plants, Karen Hokanson, David Heron, Subhash Gupta, Susan Koehler, Craig Roseland, Shanthu Shantharam, John Turner, James White, Michael Schechtman, Sally Mccammon, Rebecca Bech

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Meetings such as this workshop provide an all too rare opportunity for scientists from different disciplines to share their perspectives on a topic of common interest. In this case we examine the use of pest resistant plants in managed ecosystems. USDA-APHIS has a clear interest in this subject because it is involved in regulating transgenic plants, many of which have been engineered with some sort of pest resistance, within its broad authority to protect plants under the Federal Plant Pest Act and the Plant Quarantine Act. Since 1992, when APHIS received its first request to determine non-regulated status for a …

Report Of The Cucurbit Working Group, James D. Mccreight, Jack Staub

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Cucumber (Cucumis sativus L.) originated in India, melon (C. melo L.) and watermelon (Citrullus lanatus) in Africa, and squash, pumpkin, and gourd (Cucurbita spp.) in the Americas. Thus, cucumber, melon, and watermelon (including citron) are relatively recent introductions to the New World. Most domesticated species of Cucurbita were introduced from Mexico, Central America, and South America with the migration of native Americans centuries earlier. Wax gourd (Benincasa hispida (Thunb.) Logr.) is from Southeast Asia. Bottle gourd (Lagenaria siceraria (Molina) Stand.) is of African origin. South Asia is the probable center of …

From Stockholm To Kyoto And Back To The United States: International Environmental Law's Effect On Domestic Law, Joel B. Eisen

Law Faculty Publications

In Part I, I begin my discussion of the relationship between the two legal regimes with a brief introduction to modern international environmental law to assist those whose knowledge is as limited as mine was not too long ago. I also describe how the Allen Chair Symposium and seminar series was designed to facilitate exploration of major trends in international environmental law. Part II provides a more in-depth look at the specific relationship between domestic and international environmental law. I conclude that international environmental law informs domestic law as a wellspring of law leading to domestic innovation, a complement to …

Blocked Pathways: Potential Legal Responses To Endocrine Disrupting Chemicals, Noah M. Sachs

Law Faculty Publications

Over fifty different chemicals may have endocrine disrupting effects, and these chemicals permeate our environment. We may be exposed to them through the products we use, the food we eat, the water we drink, and the air we breath. Although there is a clear need for further research into EDCs, the legal and regulatory communities should begin to consider the types of responses that may be appropriate if the scientific evidence grows stronger.

This article describes and assesses potential legal responses to EDCs, focusing on regulation and litigation, and concludes that existing legal tools will probably be inadequate to respond …

Analysis Of Human Skin Emanations By Gas Chromatography/Mass Spectrometry. 1. Thermal Desorption Of Attractants For The Yellow Fever Mosquito (Aedes Aegypti) From Handled Glass Beads, Ulrich R. Bernier, Matthew M. Booth, Richard A. Yost

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Handled glass has the ability to collect and concentrate nonaqueous human skin emanations while minimizing the collection of aqueous perspiration. Compounds originating from the skin and collected on glass have previously been found to attract the Aedes aegypti species of mosquito. Therefore, glass beads were used as the medium to collect skin emanations from humans for subsequent chemical analysis. This process consisted of a 5-15-min collection of sample on glass beads, followed by loading the beads into a gas chromatograph (GC) injector insert for subsequent desorption of the collected compounds onto the GC column. After cryofocusing by liquid nitrogen at …

The Relative Efficacy Of Computer Assisted Instruction., Dane Edward Huxford

Graduate Theses, Dissertations, and Problem Reports (ETD)

This manuscript examines the relative efficacy of computer assisted instruction (CAI). A review of literature is examined with regard to the positive and negative aspects of the use of CAI in the university classroom. An experimental design was outlined incorporating the use of 3 teachers instructing 3 separate sections of volunteer students on a topic. The design measured the differences between affective learning, cognitive learning and student perceptions of teacher nonverbal immediacy. Participants were randomly assigned to a class, which utilized either: lecture, handout or the use of CAI. Results showed significant differences between teachers and a slight difference in …

The Effects Of Moulting On Muscle Fibre Characteristics Of The Yabby, Cherax Albidus, Tina Marie Lamey

Theses : Honours

In order to grow, crustaceans must shed their exoskeleton in a process known as "moulting'. Although this process is short and intermittent, it remains dominant over the life of a crustacean. Physiological changes in the period between moults (intermoult) are comparatively quiescent as opposed to the periods directly before and after the actual moult, known as premoult, and postmoult respectively (West, 1997). Moulting is associated with distinct physiological changes including the breakdown of muscle (Musgrove and Geddes, 1985). This muscle breakdown, known as atrophy is the diminution in size of the actual muscle mass and is very specific, occurring to …

Investigation Of The Contractile And Regulatory Proteins In Malignant Hyperthermia And Normal Skeletal Muscle, Louise C. Norbury

Theses : Honours

Malignant hyperthermia/hyperpyrexia (MH) is a serious human skeletal muscle disorder that manifests itself during general anaesthesia. Currently, the most reliable method of diagnosing this disease is the in-vitro contracture test (IVCT). This procedure is both highly invasive for the patient and expensive to perform. The skinned muscle fibre technique is less invasive, and could possibly be used as an alternative diagnostic test for MH. In this study, skeletal muscle samples were obtained from B adults (age 23-54 years) undergoing elective surgery at Royal Perth Hospital. Six patients were diagnosed as normal (controls) and two equivocal for MH (MHE). Using the …

Evaluating Oral Histories For Restoration Ecology, Margaret Robertson

Theses : Honours

Significant ecological restoration is required in the agricultural regions of south-western Australia. Environmental history, including local knowledge based on long-term observation of the biophysical environment, can help guide this process. Scientists already use local anecdotal information because other information sources are absent or too recent, yet they are often skeptical of its veracity. This study focused on whether environmental oral histories can be evaluated for factual accuracy and their capacity to be useful in the restoration process. Some of the complexities associated with linking environmental histories with restoration ecology, and the role played by oral histories in establishing the link …

Is There A Need For Speed? : Risky Driving Behaviour And Young Male Drivers : A Review Of The Literature, Catherine A. Ferguson

Theses : Honours

Young male drivers have been identified as a high risk for Motor Vehicle Accident. This paper reviews three components for accident risk: the driving environment, society and individual factors associated with accident histories. Possible predictors for identifying young men at risk for accident involvement are driving behaviour, driving attitude and sensation seeking. Protective factors to reduce the incidence of risky driving in youth might include legal restrictions, increased education and training. The paper recommends that future research tests the above predictors for a relationship with accident involvement in young men.

The Relationship Between Values And Religiosity In Adolescents, Paul F. Russell

Theses : Honours

The current work examined the areas of religiosity, values and adolescent development. The recent literature with regard to the nature of religiosity as a measure of an individual'' commitment to a particular religion was explored. The issues of measurement and definition were outlined, and a position was taken as to the multi-dimensionality of religiosity. The recent work on values by Schwartz (1992) was also explored. Values were defined and the theory of a universal set of values, as well as the relationship of values to each other was outlined, along with the organisation of those individual values into value types. …

Children's Reactions To Aggressive And Submissive Peers, Natalie Honey

Theses : Honours

The purpose of this study was to investigate children's attitudes towards aggressive and submissive peers. A 2 x 2 x 2 factorial design was used to test the hypotheses. The three between-subjects variables were (a) the label given to the target child (aggressive/submissive) in a vignette, (b) the nature of the behaviour displayed in a critical incident (aggressive/nonaggressive response) as described in a vignette, and (c) the sex of the participants. A sample of 169 Year 6 and 7 students was divided into four groups containing at least 20 girls and 20 boys. A survey was administered to measure the …

Carmoviruses (Tombusviridae), Feng Qu, Thomas Jack Morris

School of Biological Sciences: Faculty Publications

Carmovirus is one of two officially recognized genera of Tombusviridae. Members of Tombusviridae all have icosahedral virions of about 30 nm in diameter with T = 3 symmetry that consists of 180 coat protein (CP) subunits of about 38- 43 kDa and a single-stranded (ss) RNA genome ranging in size from 4.0 to 4.7 kb. Carmoviruses share recognizable sequence similarity in both the polymerase and structural genes with members of the other genus, Tombusvirus. Sequence comparisons and phylogenetic analysis of these genes support the view that the genera are distinct but closely related. In addition, the genome organization of the …

Analytical Modeling Of Cake Filtration, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The specific resistance model of cake filtration is based on the assumption that the average cake resistance is constant over time. This implies also that the spatially average values of porosity and pressure differential are also constant over time since specific resistance is a function of both parameters.

An analytical cake filtration model based on Tiller (1975) was derived using constitutive properties of kaolin suspensions in distilled water. Constitutive properties were determined by experiments performed using high-energy X-rays and porewater pressure probes to determine the spatial and temporal distributions of porosity and porewater pressure. Using these constitutive properties, predictions were …

Improvements In Modeling Dissolved Oxygen In Activated Sludge Systems, Jacek Makinia, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The aim of this research was to show the impact of the flow conditions and variations in the aeration intensity on changes in the predicted dissolved oxygen (DO) concentrations in a full-scale activated sludge reactor. The Activated Sludge Model No. 1 was used to describe the biochemical processes. The studies were performed at the Rock Creek wastewater treatment plant in Hillsboro, OR (USA). The simulation results were compared with data originating from two 24-hour experiments. The model that best reflected the spatial and diurnal distributions of the DO concentrations was the one-dimensional advection-dispersion equation with a variable overall oxygen mass …

Coordination Of Krna Editing And Polyadenylation In Trypanosoma Brucei Mitochondria: Complete Editing Is Not Required For Long Poly(A) Tract Addition, Kevin T. Militello, Laurie K. Read

Biology

Mitochondrial RNAs in Trypanosoma brucei are post-transcriptionally modified by the addition and deletion of uridylate residues in a process called kRNA editing. Unedited, partially edited and fully edited RNAs exist in the steady-state RNA population. Previous experiments have demonstrated that T.brucei mitochondrial RNAs contain both short (~ 20 nt) and long (120-200 nt) poly(A) tracts. However, it is unknown exactly what poly(A) tract lengths are present on unedited, partially edited and fully edited RNAs. To gain insight into the role of the poly(A) tract in T.brucei mitochondria, ribosomal protein S12 (RPS12) RNAs with short and long poly(A) tracts were purified …

Inhibition Of Fibronectin Matrix Assembly By The Heparin-Binding Domain Of Vitronectin, Denise C. Hocking, Jane Sottile, Thomas Reho, Reinhard Fässler, Paula J. Mckeown-Longo

Biology

The deposition of fibronectin into the extracellular matrix is an integrin-dependent, multistep process that is tightly regulated in order to ensure controlled matrix deposition. Reduced fibronectin deposition has been associated with altered embryonic development, tumor cell invasion, and abnormal wound repair. In one of the initial steps of fibronectin matrix assembly, the amino-terminal region of fibronectin binds to cell surface receptors, termed matrix assembly sites. The present study was undertaken to investigate the role of extracellular signals in the regulation of fibronectin deposition. Our data indicate that the interaction of cells with the extracellular glycoprotein, vitronectin, specifically inhibits matrix assembly …

The population for this study consisted of eighth grade students at Price Laboratory School on the Campus of the University of Northern Iowa, located in Cedar Falls, Iowa. The study was a one-group pretest-posttest design in which gain in achievement was compared to learning style. Two student groups participated in a four week unit on the structure and function …

Gender, Religion, Causal Attributions, And Correctional Orientations Among Juvenile Justice Personnel, Amy Lynn Lyons

Dissertations and Theses @ UNI

The purpose of this quantitative study is to examine the attitudes and orientations of juvenile justice personnel from four urban counties within the state of Iowa. The nonrandom sample used in the present study is secondary and originally collected for a larger study conducted by Leiber (1993). A closed-ended, self-report survey was administered to each respondent. The total sample for the present research is 263. The hypotheses guiding the present study are based on the assumption that women experience religion differently from men, and in turn, will blame society for youth crime and favor orientations supporting diversion.

Degradation Of Explosives In Solution Using Bacteria, A Fungus (Phanerochaete Chrysosporium), Titanium Dioxide, Ozone, And Electrochemical Peroxidation, Stéphane Debost

Dissertations and Theses @ UNI

As a result of munitions manufacturing and decommissioning, explosive compounds have contaminated groundwater and soils at many sites throughout the U.S. and worldwide. Three of the most commonly occurring explosive contaminants are TNT, ROX, and HMX. Many processes, biological as well as physical, have been developed to remediate the contaminated material. But feasibility studies rarely take into account the three contaminants at once. We chose four of the technologies used to remediate explosives-contaminated water and studied comparatively their effectiveness and efficiency in degrading TNT, ROX, and HMX in solution at their maximal solubilities. The chosen technologies were bacterial and fungal …

The Commonweal In The Heartland: Charles T. Kelly And Iowa's Industrial Army, Ryan James Sprau

Dissertations and Theses @ UNI

Decades before the 1930s, or the period most Americans refer to as the Great Depression, the United States suffered through one of the worst economic crises in national history. While not as devastating nor as prolonged as the economic disaster that affected the United States in the 1930s, the depression that gripped the nation from 1893 to 1897 forced millions out of work. The Commonweal of Christ, more commonly known as the industrial army movement of 1894, offered one solution to the nation's crippling unemployment problem. Crusade founder Jacob S. Coxey planned to lead the nation's unemployed and discontented into …

Tertiary Bats (Mammalia: Chiroptera) From Northern Nebraska, Nicholas J. Czaplewski, Bruce E. Bailey, Richard G. Corner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Scarce remains of bats are reported from five localities in northern Nebraska in which other kinds of vertebrates are much more common. ?Oligomyotis or ?Myotis, possibly of an undescribed species, is represented by fragments of jaws and humeri from an early Arikareean (late Oligocene) locality in Dawes County. Several toothless jaw fragments from the late Hemingfordian (middle Miocene) Companion Quarry in Sioux County represent an indeterminate microchiropteran. An indeterminate species of Myotis was encountered in the middle Clarendonian (late Miocene) Ashfall site in Antelope County. A hairy-tailed bat, Lasiurus sp. indet., occurred in late Clarendonian (late Miocene) …
