Mechanical Characterization of A2 and D2 Tool Steels By Nanoindentation

Mechanical Characterization of A2 and D2 Tool Steels By Nanoindentation

Date: May 2012
Creator: Okafor, Uzochukwu Chimezie
Description: Nanoindentation technique was used to investigate the surface properties of A2 and D2 tool steel subjected to different heat treatments. the mechanical characteristics of these two easily available tool steels were studied based on microstructural images obtained from SEM, the grain growth after heat treatment using X-ray diffraction method and nanoindentation technique. the investigation showed that a single nanoindentation result can explain how heat treatment influences reliability and failure in A2 and D2 tool steels. in this work, the causes and effects of these variations were studied to explain how they influence reliability and failure in A2 and D2 tool steel. Finally, a cube-corner indenter tip was used to determine the fracture toughness of silicon wafer. the emphasis of this research is on how nanoindentation technique is more extensive in material characterization.

Auditors’ Information Search and Documentation: Does Knowledge of the Client Preference Or PCAOB Accountability Pressure Matter?

Auditors’ Information Search and Documentation: Does Knowledge of the Client Preference Or PCAOB Accountability Pressure Matter?

Date: May 2012
Creator: Olvera, Renee M.
Description: Auditors regularly make judgments regarding whether a client’s chosen accounting policy is appropriate and in accordance with generally accepted accounting Principles (GAAP). However, to form this judgment, auditors must either possess adequate topic-specific knowledge or must gain such knowledge through information search. This search is subject to numerous biases, including a bias toward confirmation of a client’s preference. It is important to further our understanding of bias in auditors’ information search to identify its causes and effects. Furthering our understanding is necessary to provide a basis for recommending and evaluating a potential debiaser, such as accountability. the Public Company Accounting Oversight Board (PCAOB) annually inspects the audit files of selected engagements, which introduces a new form of accountability within the auditing profession. This new form of accountability has come at great cost, however, there is little empirical evidence regarding its effects on auditors’ processes. As such, it is important to understand whether the presence of accountability from the PCAOB is effective in modifying auditors’ search behaviors to diminish confirmation bias. Using an online experiment, I manipulate client preference (unknown vs. known) and PCAOB accountability pressure (low vs. high) and measure search type (information –focus or decision-focus), search depth (shallow or ...

Exploring the Relationships Between Mindfulness, Self-compassion, and Ethnic Identity Development

Exploring the Relationships Between Mindfulness, Self-compassion, and Ethnic Identity Development

Date: May 2012
Creator: Sinha, Aditi
Description: Ethnic identity development is a process that occurs for all individuals, and weakness in ethnic identity is associated with numerous psychosocial difficulties. Security in ethnic identity can be difficult for those exposed to varying attitudes and behaviors in a multicultural society. As such, the current study examined the influence of mindfulness and self-compassion on ethnic identity development. a sample of 479 undergraduate students completed online self-report questionnaires measuring demographic information, mindfulness, self-compassion, ethnic identity status, and self-esteem. Results suggested that mindfulness and self-compassion are significant negative predictors of ethnic identity, and that self-compassion was a better predictor of ethnic identity status than was mindfulness. Self-compassion did not moderate the relationship between mindfulness and ethnic identity status, as was hypothesized. the sample included primarily Caucasian (n = 278) individuals born in the United States, which likely limited generalizability of findings. Implications of the current findings and suggestions for future research are discussed.

Date: May 2012
Creator: Meckfessel, Matthew Harold
Description: The model legume, Medicago truncatula, is able to enter into a symbiotic relationship with soil bacteria, known as rhizobia. This relationship involves a carbon for nitrogen exchange in which the plant provides reduced carbon from photosynthesis in exchange for reduced, or “fixed” atmospheric nitrogen, which allows the plant to thrive in nitrogen depleted soils. Rhizobia infect and enter plant root organs, known as nodules, where they reside inside the plant cell in a novel organelle, known as the symbiosome where nitrogen fixation occurs. the symbiosome is enriched in plant proteins, however, little is known about the mechanisms that direct plant proteins to the symbiosome. Using the M. truncatula ENOD8 (MtENOD8) protein as a model to explore symbiosome protein targeting, 3-cis domains were identified within MtENOD8 capable of directing green fluorescent protein (GFP) to the symbiosome, including its N-terminal signal peptide (SP). the SP delivered GFP to the vacuole in the absence of nodules suggesting that symbiosome proteins share a common targeting pathway with vacuolar proteins. a time course analysis during nodulation indicated that there is a nodule specific redirection of MtENOD8-SP from the vacuole to the symbiosome in a MtNIP/LATD dependent manner. GFP expression by the MtENOD8 promoter revealed spatial ...

Cuff-less Blood Pressure Measurement Using a Smart Phone

Access: Use of this item is restricted to the UNT Community.
Date: May 2012
Creator: Jonnada, Srikanth
Description: Blood pressure is vital sign information that physicians often need as preliminary data for immediate intervention during emergency situations or for regular monitoring of people with cardiovascular diseases. Despite the availability of portable blood pressure meters in the market, they are not regularly carried by people, creating a need for an ultra-portable measurement platform or device that can be easily carried and used at all times. One such device is the smartphone which, according to comScore survey is used by 26.2% of the US adult population. the mass production of these phones with built-in sensors and high computation power has created numerous possibilities for application development in different domains including biomedical. Motivated by this capability and their extensive usage, this thesis focuses on developing a blood pressure measurement platform on smartphones. Specifically, I developed a blood pressure measurement system on a smart phone using the built-in camera and a customized external microphone. the system consists of first obtaining heart beats using the microphone and finger pulse with the camera, and finally calculating the blood pressure using the recorded data. I developed techniques for finding the best location for obtaining the data, making the system usable by all categories of people. ...

Date: May 2012
Creator: Turner, Lindsey Jean
Description: The purpose of this study was to identify the effect of background music in a retail setting on Generation Y students’ shopping behaviors by using the Mehrabian-Russell environmental psychology model. the study examined the impact of genre, volume, and song familiarity on purchase intention, as well as whether these musical factors would produce a change in mood. the influence of involvement with shopping on in-store music was also examined. a total of 251 students completed pre- and post-shopping surveys at the University of North Texas’ Follett Bookstore. Participants were all between 18 and 35 years of age (Generation Y). the surveys aimed to capture the participants’ entry and exit mood as well as information such as level of shopping involvement and intentions, musical awareness, overall shopping experience, and basic demographics. a positive mood change was found between entry and exit among those who were somewhat familiar and not at all familiar with the music, and entry mood affected overall shopping experience. There was a positive correlation between exit mood and the overall experience, and a negative correlation between exit mood and the amount of money spent.

Examination of Sleep Disparities Among a Racially/ethnically Diverse Sample of Adolescents

Examination of Sleep Disparities Among a Racially/ethnically Diverse Sample of Adolescents

Date: May 2012
Creator: Marczyk, Katherine D.
Description: Racial, ethnic and gender disparities have been found among a variety of health variables, but to date no study has comprehensively examined whether similar differences exist between sleep variables such as duration, efficiency and quality, in early adolescence. There is a general consensus among previous literature that adolescence is a time when a decrease in total sleep time and an increase in sleep problems are observed. Previous literature, however, mainly focused on the influence of puberty to explain these changes. the current study examined if differences exist between 1462 Caucasian, Hispanic/Latino, and African American early adolescents (ages 10-14 years) on sleep duration, efficiency and quality. Results showed that adolescent boys reported significantly longer sleep durations, better sleep quality, shorter sleep onset latencies, and later rise times than girls. Results also showed that sixth graders slept longer than seventh and eighth graders, and that seventh graders woke up much earlier than the other two grades. Lastly, results showed that Caucasian students reported longer sleep onset latencies and lower sleep efficiencies than African American students. Trends were observed for boys having greater sleep efficiencies than girls and for Caucasian students sleeping longer than Hispanic students. Based on the differences observed in our ...

Electrostatic Mechanism of Emission Enhancement in Hybrid Metal-semiconductor Light-emitting Heterostructures

Electrostatic Mechanism of Emission Enhancement in Hybrid Metal-semiconductor Light-emitting Heterostructures

Date: May 2012
Creator: Llopis, Antonio
Description: III-V nitrides have been put to use in a variety of applications including laser diodes for modern DVD devices and for solid-state white lighting. Plasmonics has come to the foreground over the past decade as a means for increasing the internal quantum efficiency (IQE) of devices through resonant interaction with surface plasmons which exist at metal/dielectric interfaces. Increases in emission intensity of an order of magnitude have been previously reported using silver thin-films on InGaN/GaN MQWs. the dependence on resonant interaction between the plasmons and the light emitter limits the applications of plasmonics for light emission. This dissertation presents a new non-resonant mechanism based on electrostatic interaction of carriers with induced image charges in a nearby metallic nanoparticle. Enhancement similar in strength to that of plasmonics is observed, without the restrictions imposed upon resonant interactions. in this work we demonstrate several key features of this new interaction, including intensity-dependent saturation, increase in the radiative recombination lifetime, and strongly inhomogeneous light emission. We also present a model for the interaction based on the aforementioned image charge interactions. Also discussed are results of work done in the course of this research resulting in the development of a novel technique for strain measurement ...

Mathematics Anxiety and Mathematics Self-efficacy in Relation to Medication Calculation Performance in Nurses

Mathematics Anxiety and Mathematics Self-efficacy in Relation to Medication Calculation Performance in Nurses

Date: May 2012
Creator: Melius, Joyce
Description: The purpose of this study is to identify and analyze the relationships that exist between mathematics anxiety and nurse self-efficacy for mathematics, and the medication calculation performance of acute care nurses. This research used a quantitative correlational research design and involved a sample of 84 acute care nurses, LVNs and RNs, from a suburban private hospital. the participants filled out a Mathematics Anxiety Scale, a Nurse Self-Efficacy for Mathematics Scale and also completed a 20-item medication calculation test. Significant practical and statistical relationships were discovered between the variables utilizing multiple linear regression statistics and commonality analysis. As the Nurse’s Mathematics anxiety score increased the scores on the medication test decreased and the scores on nurse self-efficacy for mathematics scale also decreased. the demographic item of “Hours a nurse worked in one week” had the greatest significance. the more hours a nurse worked the lower their score was on the medication calculation test. This study agrees with others that nurses are not good at mathematics. This study also correlated that as the number of hours worked increased so did the medication calculations errors. and many nurses have a measurable level of anxiety about mathematics and dosage calculations and this may influence ...

Creator: Zelman, Laura Holsomback
Description: From the earliest civilizations, victorious armies would loot defeated cities or nations. the practice evolved into art theft as a symbol of power. Cultural superiority confirmed a country or empire’s regime. Throughout history, the Greeks and Romans cultivated, Napoleon Bonaparte refined, and Adolf Hitler perfected the practice of plunder. As the tides of Second World War began to shift in favor of the Allied Powers, special commissions, established to locate the Germans’ hoards of treasure, discovered Nazi art repositories filled with art objects looted from throughout Europe. the Soviet Union Trophy Commission and the Western Allies Monuments, Fine Arts, and Archives Commission competed to discover Nazi war loot. the two organizations not only approached the subject of plunder as a treasure hunt, but the ideology motivating both commissions made uncovering the depositories first, a priority. the Soviet trophy brigades’ mission was to dismantle all items of financial worth and ship them eastward to help rebuild a devastated Soviet economy. the Soviet Union wished for the re-compensation of cultural valuables destroyed by the Nazis’ purification practices regarding “inferior” Slavic art and architecture; however, the defeated German nation did not have the ability to reimburse the Soviet State. the trophy brigades implemented ...

Hospital Readmissions: the Need for a Coordinated Transitional Care Model: Analysis and Synthesis of Research on Medicare Policy and Interventions for the Elderly

Hospital Readmissions: the Need for a Coordinated Transitional Care Model: Analysis and Synthesis of Research on Medicare Policy and Interventions for the Elderly

Date: May 2012
Creator: Wolfe, Laura M.
Description: The transition from hospital to home or alternate care setting is a time of vulnerability for all patients and particularly for our elders. If not handled appropriately there is a risk to our elders for readmission to the hospital environment that may decrease their overall quality of life and further compromise their health status. in addition to the individual risks associated with patient readmissions, there are societal impacts that reach far beyond our current generation of elders 65 and older. This impact may have dire implications for the future fiscal health of the next generation. a review of the current and past literature shows that there are a limited number of resources available for hospitals to use in order to comply with the new Value Based Purchasing initiatives that are being implemented by CMS regarding the reduction in readmission rates. the problem of hospital readmissions is confounded by the many processes that are available for study, from pre-hospitalization conditions and care through hospitalization, discharge, and finally to post discharge processes. While most research and literature reviews have focused on individual disease causes, there is a need to provide hospitals with a resource that outlines the available options and interventions that ...

Studies on Plant-aphid Interactions: a Novel Role for Trehalose Metabolism in Arabidopsis Defense Against Green Peach Aphid

Studies on Plant-aphid Interactions: a Novel Role for Trehalose Metabolism in Arabidopsis Defense Against Green Peach Aphid

Date: May 2012
Creator: Singh, Vijay
Description: Myzus persicae (Sülzer), commonly known as the green peach aphid (GPA), is a polyphagous insect that can infest over 100 families of economically important plants and is major pest for vegetable crops. This study utilizes the Arabidopsis-GPA model system with the aim to elucidate the role of the plant disaccharide trehalose in providing defense against GPA. This study demonstrates a novel role for TPS11 in providing defense against GPA. TPS11 expression was found to be transiently induced in Arabidopsis plants in response to GPA infestation and the TPS11 gene was required for curtailing GPA infestation. TPS11, which encodes for trehalose phosphate synthase and phosphatase activities, contributes to the transient increase in trehalose in the GPA infested tissues. This work suggests that TPS11-dependent trehalose has a signaling function in plant defense against GPA. in addition, trehalose also has a more direct role in curtailing GPA infestation on Arabidopsis. This work also shows that TPS11 is able to modulate both carbohydrate metabolism and plant defenses in response to GPA infestation. the expression of PAD4, an Arabidopsis gene required for phloem-based defenses against GPA, was found to be delayed in GPA infested tps11 mutant plants along with increased sucrose levels and lower starch ...

General Paul Von Lettow-vorbeck’s East Africa Campaign: Maneuver Warfare on the Serengeti

Date: May 2012
Creator: Nesselhuf, F. Jon
Description: General Paul von Lettow-Vorbeck’s East African Campaign was a conventional war of movement. Lettow based his operations on the military principles deduced from his thorough German military education and oversea deployments to China and German South West Africa. Upon assignment to German East Africa, he sought to convert the colony’s protectorate force from a counterinsurgency force to a conventional military force. His conventional strategy succeeded early in the war, especially at the Battle of Tanga in October 1914. However, his strategy failed as the war in East Africa intensified. He suffered a calamitous defeat at the Battle of Mahiwa in November 1917, and the heavy losses forced Lettow to adopt the counterinsurgency tactics of the colonial protectorate force.

Adoptive Parenthood: an Exploratory Study of the Influence of Pre-adoption Communication Satisfaction on Post-adoption Family Adjustment and Coping

Date: May 2012
Creator: Seebeck, Lara N.
Description: There are over a million adopted children in the United States, which makes up over 2% of the population. in spite of the fact that the majority of children are adopted into loving and caring homes, early life trauma puts them at higher risk for developing behavioral and emotional problems than non-adopted children. Due to these issues, many adoptive parents encounter post-adoption stress. This stress is often linked to minimal education regarding short- and long-term challenges associated with adoption. the adoption agency is likely the best group for addressing challenges, yet few researchers have studied adoption agency communication and adoptive parent adjustment. in this study I examined pre-adoption communication satisfaction, post-adoption adjustment (life change and parental adjustment), and coping strategies. Hypothesis 1 questioned the relationship between adoptive parents’ pre-adoption communication satisfaction with their social workers and post-adoption family adjustment; this hypothesis was supported only for problems related to home and work life adjustment. Hypothesis 2 predicted coping strategies would mediate the relationship between communication satisfaction and family adjustment. H2 was not supported for both life change and parental adjustment. Research Questions 1a and 1b inquired about the coping strategy that had an impact on life change and parental adjustment; escape-avoidance ...

The Myth of Strategic Superiority: Us Nuclear Weapons and Limited Conflicts, 1945-1954

Date: May 2012
Creator: Morse, Eric
Description: The nuclear age provided U.S. soldiers and statesmen with unprecedented challenges. the U.S. military had to incorporate a weapon into strategic calculations without knowing whether the use of the weapon would be approved. Broad considerations of policy led President Dwight Eisenhower to formulate a policy that relied on nuclear weapons while fully realizing their destructive potential. Despite the belief that possession of nuclear weapons provided strategic superiority, the U.S. realized that such weapons were of little value. This realization did not stop planners from attempting to find ways to use nuclear weapons in Korea and Indochina.

The Choral Music of Ola Gjeilo: a New Vision of the Choral Instrument in the 21St Century

The Choral Music of Ola Gjeilo: a New Vision of the Choral Instrument in the 21St Century

Date: May 2012
Creator: Schmidt, Brian A.
Description: The choral music of Norwegian composer Ola Gjeilo (pronounced “yay-loh”) is gaining international acclaim and is widely performed and commissioned by prominent high school, university, and professional choirs. It represents a philosophical approach and vision of the choral instrument for which the conductor must have a clear understanding in order to prepare a meaningful performance. in particular, his music merges diverse musical influences, which results in a product of unique character among choral compositions in the late 20th and early 21st centuries. Gjeilo draws inspiration from a text but then uses its sonic qualities (the sounds of vowels and consonants) to create an atmosphere of sound instead of following the traditions in choral and vocal music of using musical mechanisms (melody, rhythm, and harmony) to reinforce the text poetically. This study provides an overview of Gjeilo’s background, in Chapter 1, and discusses its influence on his compositional philosophy. Chapter 2 contains musical examples from selected works, which are used to illuminate unique attributes found in Gjeilo’s music. Chapter 3 presents important implications to consider aiding choral conductors in their preparation of future performances of Gjeilo’s music.

Ocean of Forms: for Soprano and Computer

Ocean of Forms: for Soprano and Computer

Date: May 2012
Creator: Price, Lee Scott
Description: Ocean of Forms is a cycle of five songs for solo soprano voice and electronic/computer music accompaniment on poems by noted Bengali poet, musician, philosopher, and author Rabindranath Tagore. This work approaches the song cycle as a vehicle for expressing and highlighting the poet's words. Word and syllabic stress, text painting, melodic development, and formal structure all function in relation to the text and its meaning. the replacement of the traditional piano accompaniment with electronic accompaniment provides further possibilities for new timbral structures and transformations, expressive microtonal intonation, algorithmic and aleatoric formal structures, acousmatic and spatialized sound, and a broad sonic palette. This work strives to provide a more fully developed expression of the text as afforded by these expanded musical means. the critical essay primarily explores the interaction between text and music in the work. the first chapter explores the historical precedents for the genre of the song cycle and other texted music as well as specific influences on the work. the following chapters explore the connections between the text and the vocal line and electronic/computer music, respectively. the final chapter deals with the formal structure of the work, especially the justly-tuned harmonic scheme and its relation to the ...
