Assessing The Reuse Potential Of Wastewater For Irrigation: The Removal Of Helminth Eggs From A Uasb Reactor And Stabilization Ponds In Bolivia, Matthew Eric Verbyla

USF Tampa Graduate Theses and Dissertations

Extreme hunger, malnutrition, and the lack of access to sanitation are among the most pressing development challenges, but the world is not on track to meet the targets that have been established by the Millennium Development Goals. The integration of wastewater treatment and food production systems allows for the recovery of resources from wastewater, and can provide an important solution to meet the sanitation needs of growing urban populations and provide periurban farmers with a consistent supply of water and nutrients. Stabilization ponds have been long considered to be an appropriate technology for wastewater reuse systems in developing countries, but …

Ontogeny And Littoral Structure Of Lakes Created On Phosphate Mined Lands Of Central Florida, Chrysoula Mitraki

USF Tampa Graduate Theses and Dissertations

Created lakes are an end product of phosphate mining in Florida. Beginning in 1975, Florida reclamation rules set criteria for phosphate created lakes aiming to approximate the structure of natural lakes, and emphasizing extensive littoral zones with both emergent and submersed vegetation.

Lake development relative to lake age and design were examined for 22 phosphate lakes representing a 40-year age trajectory, utilizing water quality and benthic invertebrate communities from littoral and deep-water locations (Chapter 1). The relative importance of morphometry and lake age in the development of littoral plant communities was examined using multiple vegetation surveys throughout the year, in …

Impaired Cleanance And Enhanced Pulmonary Inflammatory/Fibrotic Response To Carbon Nanotubes In Myeloperoxidase-Deficient Mice, Anna A. Shvedova, Alexandr A. Kapralov, Wei Hong Feng, Elena R. Kisin, Ashley R. Murray, Robert R. Mercer, Claudette M. St. Croix, Megan A. Lang, Simon C. Watkins, Nagarjun V. Konduru, Brett L. Allen, Jennifer Conroy, Gregg P. Kotchey, Bashir M. Mohamed, Aidan Meade, Yuri Volkov, Alexander Star, Bengt Fadeel, Valerian E. Kagan

Articles

Advancement of biomedical applications of carbonaceous nanomaterials is hampered by their biopersistence and pro-inflammatory action in vivo. Here, we used myeloperoxidase knockout B6.129X1-MPO (MPO k/o) mice and showed that oxidation and clearance of single walled carbon nanotubes (SWCNT) from the lungs of these animals after pharyngeal aspiration was markedly less effective whereas the inflammatory response was more robust than in wild-type C57Bl/6 mice. Our results provide direct evidence for the participation of MPO – one of the key-orchestrators of inflammatory response – in the in vivo pulmonary oxidative biodegradation of SWCNT and suggest new ways to control the biopersistence …

Achieving Development Impact Among Pastoral And Agro-Pastoral People: Lessons Learned In Southern Ethiopia, 2000-2009, D. Layne Coppock, Seyoum Tezera, Solomon Desta, Getachew Gebru

Environment and Society Faculty Publications

The outreach and action-research component of the Pastoral Risk Management (PARIMA) project began with a focus on the Borana Plateau of southern Ethiopia in 2000. Our goal was to use participatory methods to learn about development needs and apply the knowledge gained to benefit local communities. Today it is clear that the project has had positive impacts on the lives of thousands of people. This report helps tell this story by emphasizing the process we used.

At the start we knew that the traditional pastoral system was under intense pressure as poverty and hunger were common. Community-based problem diagnosis confirmed …

Cholesterol Dyshomeostasis And Age Related Macular Degeneration, Bhanu Chandar Dasari

Theses and Dissertations

This dissertation work focused on retinal modifications that are relevant to Age-related macular degeneration (AMD) in cholesterol-fed rabbit model of Alzheimer's disease (AD), as AD and AMD share common features. It is unknown whether cholesterol-fed rabbit model of AD displays any AMD features in retina. Previous research showed 27-hydroxycholesterol (27-OHC) involvement in AD like pathology in organotypic hippocampal slices of rabbit brain and human SHSY-5Y neuroblastoma cells. The extent to which and the mechanisms by which 27-OHC may also cause pathological hallmarks related to AMD are not known. Various studies suggested estrogen's (E2) role in AMD development. 27-OHC is a …

Effects Of A Large-Scale Wind Farm In The Prairie Pothole Region Of North And South Dakota On Survival And Habitat Use Of Breeding Female Mallards (Anas Platyrhynchos) And Blue-Winged Teal (A. Discors), Charles Tanner Gue

Theses and Dissertations

The Prairie Pothole Region (PPR) is the most important breeding habitat for North American ducks. However, much of the PPR is suitable for large-scale wind energy development and conflicts for waterfowl populations may occur if wind energy alters habitat in a way that reduces survival or productivity. Adult survival of breeding female ducks has a disproportionately large effect on population growth. Thus, populations might be particularly sensitive to increased mortality in this cohort because of direct collisions with wind turbines. Additionally, large home ranges are energetically taxing. If females avoid resources near wind turbines during breeding season activities, females may …

Genetic Relationships Of Wild Pigs (Sus Scrofa) In The United States: Geographic Origins And Genotypic Distribution Of The Species With Implications For Management, Blake Eugene Mccann

Theses and Dissertations

Wild pigs are a damaging invasive species with a long history in the United States. However, during the last 30 years wild pigs have drastically expanded their invasive range and are now present in 44 U.S. states. Though historic records provide insights regarding original introduction histories in areas where pigs are long-established, little is known regarding sources for new populations. To develop a better understanding of recent invasions, I utilized an array of molecular markers (mitochondrial DNA sequence, nuclear microsatellites, and nuclear single nucleotide polymorphisms) to evaluate both the evolutionary history of introduced pigs and gene flow between populations indicative …

Perceived Deployment Stressors And Well-Being Among Veterans Of Iraq And Afghanistan, Abigail Fuller

Theses and Dissertations

The current wars in Iraq and Afghanistan are unlike previous wars and present new challenges for service members post deployment. Currently, service members deployed to Iraq and Afghanistan are experiencing a number of stressors that may have implications during their post deployment adjustment (Kline et al., 2010; La Bash et al., 2009; McNulty, 2005). Few studies were found that examined the stressors of deployment and their relationship to the health and well-being of veterans upon return home. Therefore, a more complete understanding of the deployment experiences of Iraq and Afghanistan veterans is needed in order to have an adequate understanding …

Endorsement Clauses In A Post-White Legal System: Why These Restrictions Do Not Violate A Judicial Candidate's First Amendment Right To Free Speech, Shawna M. Portner

Georgia Law Review

Elections have remained an integral method of state
judicial appointments for over two centuries. However,
because the Founding Fathers imposed upon judges the
duty to neutrally uphold the U.S. and state constitutions,
state legislatures, per the recommendation of the ABA,
have imposed certain restrictions on the speech and
actions of judicial candidates to maintain impartiality. In
2002, the Supreme Court struck down one category of
these provisions in Republican Party of Minnesota v.
White. The Court declared Minnesota's announce clause,
which prohibited judicial candidates from voicing their
opinions on issues likely to come before the bench, to be an
unconstitutional …

Columbia Crossroads, Chad Deitchley

Institute of Metropolitan Studies Publications

Although often overlooked by residents of the urban centers that surround it, Hayden Island -- located in the midst of the Columbia River between Portland, Oregon and Vancouver, Washington -- exemplifies the kind of diverse community that defines the metroscape. With a local population of well over 2,000 and a sizable retail shopping district, Hayden Island struggles to be recognized as a destination location known for a distinctive mix of commercial, residential, and natural attributes. Its unique geographical position, however, offers both the possibility of prosperity and the threat of exploitation.

Survey Of Aquatic Invasive Species In Selected Umpqua National Forest Lakes And Ponds, Mark D. Sytsma, Rich Miller

Center for Lakes and Reservoirs Publications and Presentations

Eleven lakes and ponds within the Umpqua National Forest were surveyed for invasive aquatic macrophytes, snails, bivalves, and crayfish during the summer of 2011. Yellow floating heart (Nymphoides peltata), an invasive floating leaf macrophyte species, was detected in Willow Sump within the Little River drainage. European ear snails (Radix auricularia), an invasive species present in several Umpqua National Forest waterbodies, were detected in Beaver Pond within the Steamboat Creek drainage. One native crayfish species, the signal crayfish (Pacifastacus leniusculus), was observed in Crayfish Lake within the Brice Creek drainage. Diverse assemblages of native plant species were observed in the lakes …

Changing The Narrative Of Child Welfare, Matthew I. Fraidin

Georgetown Law Faculty Publications and Other Works

In child welfare, the difference we can make as lawyers for parents, children, and the state, and as judges, is to prevent children from entering foster care unnecessarily. And we can end a child’s stay in foster care as quickly as possible. To do that, we have to fight against a powerful narrative of child welfare and against the accepted “top-down” paradigm of legal services.

In this essay, Professor Fraidin suggests that we can achieve our goals of limiting entries to foster care and speeding exits from it by looking for the strengths of the people involved in our cases, …

Concrete Private Interest In Regulatory Enforcement: Tradable Environmental Resource Rights As A Basis For Standing, Danieli Evans

Articles

This Note proposes a novel solution to standing problems faced by environmental plaintifs seeking to enforce, or to compel agencies to enforce, environmental regulation. It argues that environmental plaintifs should be able to obtain standing to bring an Administrative Procedure Act (APA) review action or a citizen suit based on ownership of private tradable environmental resource rights, created by increasingly popular environmental privatization programs. These rights should operate as a basis for standing even for plaintifs who would otherwise be unable to meet standing requirements of individual injury, causation, and redressability. Relying on tradable rights to environmental resources as a …

The study was also designed to examine the differences in performance among different auditory memory tasks. A total of ten participants were recruited for the study. Five typically developing individuals served in the control group and five individuals with a clinical diagnosis of CAPD served in the experimental group. Results from the study indicated that individuals with a diagnosis of CAPD performed significantly lower than the control group on …

Non-Traditional Distance Learners: Student Persistence In A Rural Remote Community, Paula Ann Sundet Wolf

Theses and Dissertations

Cook County Higher Education (CCHE), a non-profit distance education resource center located in rural northeastern Minnesota, has student completion rates of 90% and higher. CCHE has attributed the student persistence to its external support services, such as mentoring, technology support, study skills, attitude, and financial resources. With the national call for increased degrees per capita, there is also increased incentive for higher education institutions to become more creative in offering external support services to their non-traditional distance learning students. This grounded theory method research project explored rural students' perceptions of what motivates them to persist in distance learning programs. Thick, …

The Five-Factor Model As Predictor Of Performance On Decision-Making Tasks, Darci Van Dyke

Theses and Dissertations

Prior research on personality and decision-making has failed to use adequate measurement of both constructs. The current research extended the previous literature by incorporating multiple measures of decision-making as well as the NEO-PI-3, a psychometrically sound measure of the five-factor model of personality. Five measures of decision-making were used which addressed various aspects of adequate decision-making. The current research also included a measure of cognitive ability (WAIS-IV Vocabulary) as previous research has noted a strong correlation between cognitive ability and decision-making. Results indicated that cognitive ability significantly predicted performance on three decision-making tasks. In regard to personality, Agreeableness was the …

The Urotsa Bladder Cell Model For Heavy Metal Carcinogenesis: Characterization With Respect To The Role Of Beclin-1 And Sparc Expression, Jennifer Larson

Theses and Dissertations

The development of bladder cancer is known to have a strong association with environmental toxins. This laboratory employs the human Urotsa cell line model to explore the relationship between As+3 and Cd+2 exposure and the development of urothelial cancer.

The parental Urotsa cells and their As+3 and Cd+2 transformed counterparts have been used to define the mechanism of cell death (apoptosis and/or necrosis). A third mechanism of cell death, autophagy, has not yet been investigated. The hypothesis for the current study is that the autophagy pathway involving beclin-1plays a role in Urotsa cell death mechanisms. A combination of real time …

'Reel' Gangs Or 'Real' Gangs: A Qualitative Media Analysis Of Street Gangs Portrayed In Hollywood Films, 1960-2009, Christopher J. Przemieniecki

Theses and Dissertations

The purpose of this qualitative study is to explore the portrayals of street gangs as presented by a select sample of Hollywood films from 1960 to 2009. Using the theoretical framework of social constructionism and cinematic realism, a content analysis of 25 `street gang' films was conducted to (a) determine the comparability of depictions of street gangs in Hollywood films with those characteristics of defining a street gang in the law enforcement and academic literature, (b) identify emergent themes and patterns, including changes over time, and (c) address the representations of realism in the portrayal of street gangs as depicted …

Roles Of Ccaat/Enhancer-Binding Protein [Beta] And [-Delta] In Immunoglobulin G Immune Complex-Induced Inflammation, Chunguang Yan

Theses and Dissertations

CCAAT/enhancer-binding protein (C/EBP) &beta and C/EBP&delta are known to participate in the regulation of many genes associated with inflammation. However, little is known about the activation and function of C/EBP&beta and -&delta in inflammatory responses elicited by Fc&gamma receptor (Fc&gammaR) activation. Here I showed that C/EBP&beta and -&delta activation were induced in immunoglobulin G immune complex (IgG IC)-treated macrophages by using gel shift assays. The increased expression of C/EBP&beta and -&delta occurred at both mRNA and protein levels. Furthermore, induction of C/EBP&beta and -&delta was mediated, to a large extent, by activating Fc&gammaRs. Using small interfering RNA (siRNA)-mediated knockdown as …

Evaluation Of A Low Corrosion Method To Increase Mercury Oxidation And Scrubber Capture, Shuchita Sanjay Patwardhan

Theses and Dissertations

The taconite industry located in the Mesabi iron range has been identified as one of the major contributors of the atmospheric mercury in the Lake Superior basin by the Lake Superior Lakewide Management Plan (LaMP). Mercury is a leading concern among air toxic metals due to its volatility, persistence and bioaccumulation as methylmercury in the environment, and its neurological health impacts.

Previous research work performed at taconite processing plants by Minnesota Department of Natural Resources (DNR) identified the taconite ore as the main source of mercury during the taconite processing. Magentite iron ore pellets are produced by balling moist concentrates …

A Phenomenological Exploration Of The Childfree Choice In A Sample Of Australian Women, Joanne Doyle, Julie Ann Pooley, Lauren Breen

Research outputs 2012

Choosing not to have children is considered a deviation from cultural norms, particularly the dominant pronatalist discourse; this is especially so for women. However, little research has documented the experience of Australian women who have consciously chosen to remain childless. Ten voluntarily childfree women participated in unstructured interviews about their choice and its ramifications. The data analysis revealed three broad themes – the experiences and processes of making the choice; the ongoing effects of their choice, ranging from support and acceptance to pressure and discrimination; and no regret as the women described engaging in meaningful, generative activities that contributed to …

The Use Of Naltrexone In Pregnancy In Opiate-Dependent Mothers, Sadie Geraghty, Carly Dixon

Research outputs 2012

There is an absence of sufficient evidence regarding naltrexone use in pregnancy due to the limited range of human studies. Naltrexone implants are being used in Western Australia as a treatment for opioid dependency, and although contraindicated for insertion during pregnancy, there are a number of women who conceive while undergoing treatment. A review of the available data revealed that naltrexone is associated with improved maternal and fetal outcomes. Extensive research into this area in the form of large, multicentre trials is required to confirm the results of the current research.
