Congestion Avoidance Energy Efficient Mac Protocol For Wireless Sensor Networks, Alexander Sundling

Boise State University Theses and Dissertations

Wireless Sensor Network (WSNs) are generally energy-constrained and resource-constrained. When multiple simultaneous events occur in densely deployed WSNs, nodes near the base station can become congested, decreasing the network performance. Additionally, multiple nodes may sense an event leading to spatially-correlated contention, further increasing congestion. In order to mitigate the effects of congestion near the base station, an energy-efficient Media Access Control (MAC) protocol that can handle multiple simultaneous events and spatially-correlated contention is needed. Energy efficiency is important and can be achieved using duty cycles but they could degrade the network performance in terms of latency. Existing protocols either provide …

Analysis Of Electromagnetic Stimulation Of Transport In Water For Geoenvironmental Applications, Mahsa Azad

Boise State University Theses and Dissertations

Air sparging is a popular soil and groundwater remediation technique, which enables the removal of volatile organic compounds (VOCs) through diffusing contaminant-free air into saturated zones of soil. However, the VOC removal process is slow due to the soils' low permeability, and might take months to years depending on the type of the soil and contaminant. The goal of this thesis is to study the effect of electromagnetic (EM) waves —with minimal heat generation— on transport mechanisms such as diffusion, in order to improve airflow and expedite the cleanup process using air sparging or similar technologies. Because water dipole molecules …

Nitrite Oxidation In Geothermal Springs: Evidence Of An Upper Temperature Limit For Thermophilic Nitrite-Oxidizing Bacteria Of 60 - 65 °C, Tara Edwards

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite growing evidence of the importance of nitrification in terrestrial geothermal environments, little is known about nitrite oxidation in these environments. In order to further our knowledge, this study combined cultivation-dependent and -independent approaches with measurements of nitrogen speciation along the outflow channels of two Great Basin geothermal springs. Enrichment cultures were inoculated with sediment slurries from sites ranging in temperature from 42 - 87 °C at the sources and along the outflows of >15 hot springs. While attempts to enrich nitrite-oxidizing bacteria (NOB) from sites greater than or equal to 61 °C were unsuccessful, NOB were enriched from five …

Sociosexuality, Mate Preferences, And Sex Steroid Hormone Levels Among Breastfeeding Women In Manila, Michelle Escasa

UNLV Theses, Dissertations, Professional Papers, and Capstones

This project investigates the influence of lactation on female sociosexuality and mate preferences in urban Manila, a population with long-term breastfeeding, low contraceptive use, and quick return to ovulatory cycling. Physiological and evolutionary considerations suggest that lactating women face important life history allocation trade-offs between mating and parenting effort that may be manifest in their sociosexual behavior and mate preferences. Breastfeeding (n=155) and control (n=105) women were recruited to provide a saliva sample (for testosterone and estradiol analyses), complete a questionnaire, and complete a face and voice preference task to determine preferences for masculinity. Breastfeeding women reported differences in commitment …

Innovators And Laggards? Faculty Adoption Of Online Distance Education, Thomas Tailor Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over the past decade, institutions of higher education have seen enrollments in distance education, especially in the form of online learning, proliferate in striking numbers. In fact, some traditional colleges and universities are only experiencing real institutional growth in the areas of online learning. Even though a major push to increase the availability of distance education technology has occurred, effective adoption has not always followed suit. In hopes of speeding up the diffusion process, many colleges and universities have begun to contemplate the increased integration and institutional adoption of online learning. One of the most critical factors administrators must consider …

Hematopoietic Stem Cell Threshold Sensing Controls Regulatory Pathways Facilitating Clinically Relevant Ex Vivo Expansion For Stem Cell Transplantation, Andrew D. Lasiter

Theses and Dissertations (ETD)

The ex vivo expansion of hematopoietic stem cells (HSCs) for transplantation has threefold importance: 1.) First, because of the rarity of stem cells there often isn’t a sufficient supply obtainable from common sources for larger children and adults. 2.) Secondly, patient morbidity and time to hematopoietic reconstitution following myeloablative preconditioning is improved by administering a larger pool of HSCs. 3.) Lastly, gene therapies for hematological diseases still require a robust supply of HSCs to offset varying degrees of inefficiency in vector mediated transfection protocols. These reasons, and others, have been an impetus for many discoveries made within four primary subdivisions …

Effect Of Compression Force On Agglomeration Of Micronized Active Pharmaceutical Ingredients: Techniques To Prevent Api Agglomeration During Compression, Suresh Potharaju

Theses and Dissertations (ETD)

Micronization is one of the common processes for size reduction to increase surface area of poorly soluble Active Pharmaceutical Ingredient’s (API). This size reduction improves the dissolution rate and permeability thereby increasing the bioavailability for hydrophobic API’s.

Tablets and capsules are the most marketed and easy to manufacture solid dosage forms. During manufacturing of tablets, high compression forces are applied uniaxially on the powder bed to get a coherent consolidated compact with good tensile strength. So, diluents are required to mix with API’s and compress into tablets. When this mixture is compressed into tablets, there is a possibility of agglomeration …

Order Without Judges: Customary Adjudication, Joseph Blocher

Duke Law Journal

Scholarship on custom and law has largely focused on the creation and enforcement of informal rules, demonstrating and in some cases endorsing the existence of "order without law." But creating and enforcing rules are only two of the three functions of governance, corresponding roughly with what in other contexts are called the legislative and executive branches. The third function—adjudication—has not played such a prominent role in the scholarly literature on informal governance. As one leading scholar puts it: "Custom has no constitution or judges." But if customs can be created and enforced by nonstate actors, why should scholars assume that …

The Plymouth Student Scientist

This study investigated the effects of priming a Lad’s magazine brand on women’s perceptions of the sexual harassment of other women and their notions of women as sex objects. Previous research has demonstrated perceptions of women can be affected by media exposure. Past studies were reviewed and a gap was identified in the current knowledge of the effects of exposure to sexualised media on women’s perceptions of the sexual harassment of other women. One-way ANOVAs did not demonstrate any statistically significant differences in women’s perception of the sexual harassment of other women or notions of women as sex objects in …

Fluorescent Proteins And Chromoproteins In Phylum: Cnidaria, Mario Lewis

The Plymouth Student Scientist

Green fluorescent protein was first discovered in Aequorea victoria. Its significance in a continually expanding range of scientific applications led to the discovery of an abundance of homologous fluorescent proteins and non-fluorescent chromoproteins in a variety of species in the phylum Cnidaria. The document reviews the various proposed hypotheses on the biological functions and biochemistry of fluorescent proteins and chromoproteins, wherein a full resolution remains elusive and is the subject of on-going debate. Mutagenesis has provided novel variants and insights into the relationship between the spectral characteristics and chromophore structures of fluorescent proteins that encompass the visible spectrum. Fluorescent proteins …

Effects Of Algal Toxicity On The Clearance Rate Of The Blue Mussel (Mytilus Edulis), Samantha Bowgen

The Plymouth Student Scientist

The purpose of this study was to investigate the effect of toxic strains of Karlodinium veneficum on the clearance rate of Mytilus edulis. Suspensions of the toxic strain and the non-toxic strain of K. veneficum, mixed with an alternative non-toxic species, Prorocentrum micans, were made and performed as parallel experiments in order to compare their effects on clearance rate. Clearance rate was measured by taking samples from suspensions every five minutes up to 30 minutes, and counting the algal cells found within each sample using a Sedgewick rafter slide. No significant difference was found between the two experiments (F (9.322, …

The Effect Of Itgd Sensitivity And Contact On Attitudes Towards Burqas, Sophie Augarde

The Plymouth Student Scientist

The presented research investigates whether intergroup disgust sensitivity (affect-laden construct reflecting individual differences to experience revulsion towards outgroups) predicts greater prejudicial attitudes towards burqas. In addition to investigating the effect of ITGD sensitivity on prejudicial attitudes, types of contact (no contact, imagined contact and physical contact) between participants and an outgroup member were investigated to assess the efficacy of reducing prejudice towards women who wear burqas. ITGD sensitivity along with attitude towards burqas was measured over two sessions. Results indicated that there was no statistically significant effect of ITGD sensitivity or contact type on attitudes towards burqas. However, mean score …

Biologging Science: Advances In Our Knowledge Of Seabirds And Their Behaviours, David Evans

The Plymouth Student Scientist

The use of miniature tags attached to free-living animals to record data is termed ‘biologging’. This procedure has been used to study seabirds since the 1970’s and our knowledge of their behaviour, physiology and migration has advanced through the decades, along with the potential for conservation of species. Technological advances in recent years have improved data resolution and storage, enabling a better understanding of seabirds and their environment

Mood Affective Outcomes From Alternate Learning Strategies: Cognitive Flexibility And Dyslexic Education, Dylan Williams

The Plymouth Student Scientist

It is theorized that persons with dyslexia and associated conditions may be vulnerable to negative wellbeing, alongside academic deficiency, which has been focused on more widely. This study aims to investigate this theory in teenagers, and to draw relationships with teaching methods. Participants were interviewed, and completed the PANAS (Positive and Negative Affect) scale for children, the Matson Evaluation of Social Skills for Youngsters, and the Educational Environment Survey (an assessment of perceptions on education and ability). Participants with dyslexia and associated conditions showed reduced wellbeing compared to controls, and identified distinct experiential differences of education. This study was successful …

From Future Homemaker Of America To The Lesbian Continuum: The Queering Of Mary Ann Singletone In Armistead Maupin's Tales, Sara Katherine White

Masters Theses and Doctoral Dissertations

Armistead Maupin's Tales of the City is a turning point in homosexual literature in twentieth century America. This paper mainly examines the character of Mary Ann Singleton and the "queering" of her character. The writings of Michael Foucault, Judith Butlter, Adrienne Rich, Eve K. Sedgewich, and Simone de Beauvoir are vital in understanding how a straight woman journeys onto the lesbian continuum as a revolt against gender roles (defined by Butler and Beauvoir) and as a result of her friendship with Michael Tolliver. Michael's character provides a discourse (as defined by Foucault) on homosexuality and through this discourse, he provides …

The purpose for this study was to examine the relationship between specific variables involved in co-teaching (preparation for co-teaching training, collaborative practices, selection process of co-teaching pairs, and use of specialized instruction) and student mathematics achievement as reported by a standardized test administered in the spring of each year. The study focused on the mathematics test results of fifth and eighth grade special education students in co-taught math classrooms.

The researcher conducted the study …

Polymer Surface Engineering Via Thiol-Mediated Reactions, Ryan Matthew Hensarling

Dissertations

Synthesis of polymer brushes to decorate a surface with desired functionality typically involves surface-initiated polymerization (SIP) of functional, but non-reactive monomers. This approach suffers major drawbacks associated with synthesizing sufficiently thick polymer brushes containing surface-attached polymer chains of high molecular weight at high grafting density (i.e. cost, synthetic effort and functional group intolerance during polymerization). The research herein seeks to circumvent these limitations by the decoration of surfaces with polymer chains bearing specific pendent functional groups amenable to post-polymerization modification (PPM). In particular, this dissertation leverages PPM via a specific class of click reactions – thiol-click – that 1) enables …

Singing Songs In A Strange Land: The Plight Of Haitian Children In The Space Of International Adoption., Glenys P. Spence

The Scholar: St. Mary's Law Review on Race and Social Justice

The best interests of children are not served by severing the familial bonds contemplated by international adoption law. Nonetheless, because of the high costs of the international adoption process, efforts to adopt their Haitian orphan relatives are ignored. In attempts to guarantee the “best interests of the child” are met, the United Nations Convention on the Rights of the Child (CRC) and the Hague Convention on the Protection of Children Co-Operative Respect of Intercountry Adoptions (Adoption Convention) were created as the two governing bodies of international adoption law. Global South countries, including Haiti, however, have not ratified the Adoption Convention. …

The Thirteenth Amendment Won't Help Free Willy., Sheri Flannery

The Scholar: St. Mary's Law Review on Race and Social Justice

Orcas are not afforded any relief under the Thirteenth Amendment. Animal rights advocates, namely People for the Ethical Treatment of Animals (PETA), alleged animals have the right to be free from slavery and involuntary servitude as guaranteed by the Thirteenth Amendment. Although the Thirteenth Amendment has been extended beyond African slavery, its protections have never been granted to anything other than human beings. The United States Supreme Court’s examination and interpretation of the Thirteenth Amendment concluded that animals are not afforded such protections under this amendment. The Court reasoned that the Thirteenth Amendment only applied to humans and not animals. …

Racial Identity Attitudes, Perceived Barriers, Career Self-Efficacy, And Career Outcome Expectations Among African American Male Adolescents., Norman L. Townsel 1960-

Electronic Theses and Dissertations

Social Cognitive Career Theory (SCCT) holds that self-efficacy and outcome expectations are primary predictors of career choice goals and actions, with contextual influences moderating those choices and actions. Racial identity research indicates that African American adolescents perceive more barriers than their White counterparts. The current study hypothesized that chronological age, racial identity attitudes, and the perception of barriers would be significant influences on self-efficacy and outcome expectations for African American adolescents. The study explored the research question using two separate stepwise regression analyses. The first analysis explored racial identity attitudes, age, and perceived barriers in relation to self efficacy. The …
