Control Of Hydrogen Sulfide Emissionsusing Autotrophic Denitrificationlandfill Biocovers, Daoroong Sungthong
Electronic Theses and Dissertations
Hydrogen sulfide (H2S), a major odorous component emitted from construction and demolition debris landfills, has received increasing attention. Besides its unpleasant odor, long-term exposure to a very low concentration of H2S can cause a public health issue. Although cover materials such as soil and compost are recommended to be used routinely to control an odor problem from the landfills, the problem still remains. Autotrophic denitrification may have environmental applications including treatment of water, groundwater, wastewater or gaseous streams contaminated with sulfur and/or nitrogen compounds. However, there have been no studies reported in the literature on H2S removal using autotrophic denitrification …
Experimental Analysis On The Effects Of Superficial Liquid And Gas Velocities In The Removal Of Hydrogen Sulfide From A Brine/Oil Mixture, Joshua Lee
Electronic Theses and Dissertations
Hydrogen Sulfide (H2S) is a harmful gas produced during petroleum extraction that leads to corrosion of drilling tools and pipelines. However, a H2S-scavenging liquid compound, when added to pipelines, interacts with liquids that absorbed H2S to create a non-corrosive bi-product. The interaction is associated with the mixing of gases and liquids. This thesis is a study on the effect of superficial gas and liquid velocities on the scavenger's efficiency. This study employs two experimental setups designed to simulate the mixing of gases and liquids within pipelines. A high pressure closed loop was designed and fabricated to determine the influence of …

Assessment Of Aquifer Storage And Recovery Impact On Phosphorus Stability In Lake Sediment, Sha Liu
Electronic Theses and Dissertations
Lake Okeechobee, the second largest natural freshwater lake in the United States, had experienced a historical drought in 2007-2008 and the inflow to Lake Okeechobee has been reduced by 40% of the average daily mean between warm phase and cold phase due to the impact of Atlantic Multidecadal Oscillation in the past six decades. To cope with this water resources management problem, the US Army Corps of Engineers (USACE) proposed the largest national implementation plan of aquifer storage and recovery (ASR) project in the Kissimmee River Basin. Routine operation of ASR will deliver recovered water from ASR wells into the …
A New Development Of Feedback Controller For Left Ventricular Assist Device, Yu Wang
A New Development Of Feedback Controller For Left Ventricular Assist Device, Yu Wang
Electronic Theses and Dissertations
The rotary Left Ventricular Assist Device (LVAD) is a mechanical pump surgically implanted in patients with end-stage congestive heart failure to help maintain the flow of blood from the sick heart. The rotary type pumps are controlled by varying the impeller speed to control the amount of blood flowing through the LVAD. One important challenge in using these devices is to prevent the occurrence of excessive pumping of blood from the left ventricle (known as suction) that may cause it to collapse due to the high pump speed. The development of a proper feedback controller for the pump speed is …

Habermas And The Feminist Engagement With Communicative Ethics: Solidarity And Utopian Interests As A Corrective To Normative Political Problematics, Taine Duncan
Electronic Theses and Dissertations
My dissertation subjects Habermas to a critique inspired by ethical and political feminist philosophy. Whereas Habermas believes particularized political interests are foundational for communicative ethics, neo-Marxist feminists argue that he makes naïve assumptions about the separation of public from private interests. Habermas, on one hand, sees communication as politically oriented dialectics that culminates in rational consensus and normative guidelines. Seyla Benhabib, on the other hand, claim that Habermas' notion of consensus is obtained through false dialectical syntheses. In her view, Habermas cannot preserve the utopian goals cherished by diverse and marginalized members of society. Benhabib thus attempts to reconcile contemporary …

Synthesis Of Analogues Based On The Opioid Alkaloid Mitragynine, Marco A. Arribas
Synthesis Of Analogues Based On The Opioid Alkaloid Mitragynine, Marco A. Arribas
Electronic Theses and Dissertations
Opioid analgesics such as morphine and its derivatives are the most frequently prescribed narcotics for the treatment of severe and chronic pain. Among other side effects caused by the administration of these opioid analgesics, physical dependence and addiction are the most undesirable ones. Currently, pharmacological approaches to treat opioid dependence include mainly methadone and LAAM (mu-agonists), buprenorphine (mu-partial agonist) and clonidine (alpha2-adrenergic agonist). Considering the negative aspects of the relapsing nature correlated to opioid dependence, it is important to search for new ways to overcome this problem. The scope of this work is to study novel compounds based on the …

Religion And Identity Formation A Cross National Comparison Of College Students In India & The Usa, Niyatee Sukumaran
Religion And Identity Formation A Cross National Comparison Of College Students In India & The Usa, Niyatee Sukumaran
Electronic Theses and Dissertations
With the exception of a few studies (Leak, 2009; Fulton, 1997), psychological research on religion has not been studied from an Eriksonian identity status perspective (Erikson, 1959; Marcia, 1966). Further, Erikson’s (1963) concept of identity appears to be inherently individualistic and may be conceptualized differently in Eastern/Asian cultures (Cloninger, 2008; Paranjpe, 2010). This study aims to understand the relationship of religiosity and quest to identity development across two cultures: USA and India. A total of 326 undergraduate students (mean age= 19.47, sd= 1.58) participated from two urban colleges in Mumbai, India (n= 159) and one in Orlando, USA (n= 167). …

Preparation And Characterization Of Lyophilized Cyclodextrin Complexes Of A Hemisuccinate Ester Of Delta-9-Tetrahydrocannabinol For Transmucosal Delivery, Sampada Bhaskar Upadhye
Electronic Theses and Dissertations
Delta-9- Tetrahydrocannabinol (THC) is the primary active ingredient of the plant Cannabis sativa (marijuana), responsible for the majority of the pharmacological effects. The most promising clinical applications of THC approved by the Food and Drug Administration (FDA) are for the control of nausea and vomiting associated with chemotherapy and for appetite stimulation of AIDS patients suffering from anorexia and wasting syndrome. The only dosage form currently approved by FDA is an oral, soft gelatin capsule (e.g. Marinol®). In addition, orally administered THC from Marinol® has shown slow and variable absorption due to low oral solubility and first pass metabolism. Our …
The Role And Effectiveness Of Proactive Behaviors As Coping Strategies In The Stress Process, Laura Anne Williams
The Role And Effectiveness Of Proactive Behaviors As Coping Strategies In The Stress Process, Laura Anne Williams
Electronic Theses and Dissertations
Within the organizational sciences, researchers have examined the stress process in an effort to identify the antecedents and consequences of strain as well as moderating variables which exacerbate or ameliorate the negative effects of strain on individuals and organizations. Limited research has considered the role proactive behaviors may play as neutralizers of the negative consequences of stress. In this study, I seek to expand our knowledge of the role and effectiveness of proactive behaviors within the stress process. Using a job crafting framework, three categories of proactive behaviors (task-oriented, cognitive-oriented, and relationship-oriented) will be examined and are hypothesized to be …

This research is prerequisite to determining structural health and estimating wear-limited life of contact/impact machinery components. Prevention, or at least early notification, of impact-induced wear is essential for preventing economic loss and enhancing personnel safety. Thus, an efficient model which is discrete in time and continuous in space was undertaken; an euler-bernoulli beam with adjustable boundary conditions and variable impact is numerically studied under a pulse loading. Structural stiffness, material modulus, contact stiffness, contact location, damping ratio, pulse duration, clearance and boundary conditions are investigated. A reference system is used as the basis for parameter studies and solution convergence is …
Determinants Of Bone Mineral Density In African-American And Caucasian College-Aged Women, Andrea K. Johnson
Determinants Of Bone Mineral Density In African-American And Caucasian College-Aged Women, Andrea K. Johnson
Electronic Theses and Dissertations
Osteoporosis is a serious health issue affecting 10 million Americans, with an additional 44 million being at risk. Due to the morbidity and mortality associated with fractures caused by osteoporosis, it is an important public health concern. Some researchers suggest that African-American women fracture at a lower rate when compared to Caucasians with the same bone mineral density (BMD). However, when African-American women do fracture, they have higher mortality and morbidity rates. Data regarding risk factors and prevalence of low BMD among African American and Caucasian college-aged women are limited. Purpose. The primary purpose of this research was to explain …

A Screen Of One's Own The Tpec And Feminist Technological Textuality In The 21st Century, Amy J. Barnickel
Electronic Theses and Dissertations
In this dissertation, I analyze the 20th century text, A Room of One's Own, by Virginia Woolf (2005), and I engage with Woolf's concept of a woman's need for a room of her own in which she can be free to think for herself, study, write, or pursue other interests away from the oppression of patriarchal societal expectations and demands. Through library-based research, I identify four screens in Woolf's work through which she viewed and critiqued culture, and I use these screens to reconceptualize "a room of one's own" in 21st Century terms. I determine that the new "room" is …
