Instabilities Of Volatile Films And Drops, Nebojsa Murisic

Dissertations

We report on instabilities during spreading of volatile liquids, with emphasis on the novel instability observed when isopropyl alcohol (IPA) is deposited on a monocrystalline silicon (Si) wafer. This instability is characterized by emission of drops ahead of the expanding front, with each drop followed by smaller, satellite droplets, forming the structures which we nickname “octopi” due to their appearance. A less volatile liquid, or a substrate of larger heat conductivity, suppress this instability. In addition, we examine the spreading of drops of water (DJW)-JPA mixtures on both Si wafers and plain glass slides, and describe the variety of contact …

Data Allocation In Disk Arrays With Multiple Raid Levels, Jun Xu

Dissertations

There has been an explosion in the amount of generated data, which has to be stored reliably because it is not easily reproducible. Some datasets require frequent read and write access. like online transaction processing applications. Others just need to be stored safely and read once in a while, as in data mining. This different access requirements can be solved by using the RAID (redundant array of inexpensive disks) paradigm. i.e., RAIDi for the first situation and RAID5 for the second situation. Furthermore rather than providing two disk arrays with RAID 1 and RAID5 capabilities, a controller can be postulated …

Optimal Allocation Of Blood Products, Godson A. Tetteh

Dissertations

The high cost of collection and the short shelf life of apheresis platelets demand efficient inventory management to reduce outdates and shortages. Apheresis platelets are licensed for seven days, and blood centers are keen on knowing the consequences of various product collection and distribution strategies. To reduce outdates, inventory managers typically distribute the older units first, thereby following first-in first-out (FIFO) policy; however, hospital blood banks would prefer that the blood center issues out the freshest units first, equivalent to a last-in first-out (LIFO) policy. This study addresses the optimal distribution policy to achieve a desired outdate, shortage and average …

Vector Support For Multicore Processors With Major Emphasis On Configurable Multiprocessors, Hongyan Yang

Dissertations

It recently became increasingly difficult to build higher speed uniprocessor chips because of performance degradation and high power consumption. The quadratically increasing circuit complexity forbade the exploration of more instruction-level parallelism (JLP). To continue raising the performance, processor designers then focused on thread-level parallelism (TLP) to realize a new architecture design paradigm. Multicore processor design is the result of this trend. It has proven quite capable in performance increase and provides new opportunities in power management and system scalability. But current multicore processors do not provide powerful vector architecture support which could yield significant speedups for array operations while maintaining …

An Analysis Of Mer1 Function During Meiotic Splicing Regulation In Saccharomyces Cerevisiae, Frederick William Scherrer

Dissertations

The transition from mitosis to meiosis in the yeast Saccharomyces cerevisiae requires a significant change to gene expression profiles. Regulation of pre-messenger RNA splicing patterns during meiosis assists in this transition by fine tuning expression of essential meiotic genes. Produced only during meiosis, Mer1p is linked to the splicing of at least three mRNAs: MER2, MER3, and AMA1. Previous evidence suggests that Mer1p activates splicing by directly recruiting snRNPs or stabilizing intermediate splicing complexes formed on pre-mRNA that contains an intronic Mer1p enhancer element. However, some splicing factors, especially accessory/non-snRNP factors, have critical roles in retaining unspliced pre-mRNAs in the …

A Systematic And Taxonomic Review Of The Family Pseudotanaidae (Crustacea: Peracarida: Tanaidacea) Based Primarily On Morphometry Cladistic Analyses, Jerry Alan Mclelland

Dissertations

Species of the tanaid family Pseudotanaidae, established by Jurgen Sieg in 1973, have been reported from all the world's oceans in depths ranging from near the surface to below 6,000 m. The family currently consists of 46 characteristically small tanaidomorph species residing in two subfamilies, the Cryptocopinae (seven species) and the Pseudotanainae (39 species). Members of the more ancestral Crytocopinae differ from the Pseudotanainae by having females with four rather than three antennule articles and a complete separation of the maxilliped endites. The primary objective of this study was to test the hypothesis that the current structure of the family …

Power Base Perceptions Of School Administrators At Residential Schools For The Culturally Deaf, Allison Washington Moffett

Dissertations

Residential schools fill a significant role in the academic and social education of deaf and hard-of-hearing students worldwide. Progress has been made in these schools as a result of a collaborative effort between schools and community working together. Administrators at the residential schools play essential roles in the academic and social processes of education and as such they must be aware of their own power bases and usages. Hersey and Blanchard (1993) maintained that it is essential for school administrators to be able to distinguish the power sources and to be knowledgeable about which power sources to use in a …

Attacking Ethos: The Rhetorical Use Of Uncertainty In The 2004 Election, Theron Allen Verdon

Dissertations

The rhetorical use of uncertainty in political communication (and other areas) has many implications. Uncertainty plays a major role in everyday life. Therefore, it likely plays a major role in political decision-making. Research has shown that uncertainty about a candidate affects a voter's voting preference. Uncertainty usually affects voter decisions. Uncertainty was a factor in the 2004 presidential election. The Bush-Cheney Campaign used uncertainty to corrupt the ethos of the Democratic nominee, Senator John Kerry. The Bush-Cheney campaign rhetorically manipulated information about Senator Kerry to create a perception of a leader whose actions revealed an unpredictable flip-flopper. A lack of …

Economic Inequality In The New European Union: Are Monetary Policies In The European Union Unfair For Certain Countries?, Gregory Eric Banach

Dissertations

This research is focused on the affect one uniform monetary policy will have on the less developed countries that entered the European Union (EU) in 2004. One of the challenges facing the new entrants involves the required implementation of monetary policy goals, even though these new entrants do not have a vote on how the monetary policy is determined. Monetary policy in the EU is the responsibility of the European Central Bank (ECB) who has a stated goal price stability. It is possible to use the Taylor Rule to test whether the ECB focuses on price stability for both old …

We Become Delicate Boats: Poems And Essays, Deja Anne Earley

Dissertations

My collection of poems and essays, We Become Delicate Boats, takes inspiration from a broad range of sources that shift into each other: paintings, pop culture, literary figures, dreams, relationships, faith, family, history. For example, some poems throw together unexpected bedfellows, like Kafka's Gregor Samsa and Marie Antoinette; others are anecdotal, like one that describes going on a blind date with a man who actually turns out to be blind, some re-imagine stories we already know, like one in the voice of Medusa, talking about which occasions call for her various snake "wigs." Although quite a few pieces are playful, …

How Spirituality Impacts Ethical Leadership: A Cross-Case Analysis Of Eleven Corporate Chief Executive Officers, Mary Rose Johnson Edd

Dissertations

Almost weekly, there are news accounts of corporate and government leaders breaching ethical and moral standards. Indeed, in recent years, corporate corruption and misrepresentation of the truth have appeared overwhelming. At the very least, corporate and government scandals suggest that there is currently a crisis in leadership. A Spiritual Audit of Corporate America by Mitroff and Denton, a book called a “landmark contribution” by prominent leadership scholar Warren Bennis, found that individuals and organizations that have a strong sense of spirituality are “far less likely to compromise their basic beliefs and values.” Their data suggested that spirituality may serve as …

An Ethnography Study Of Hiv Positive Midlife Black Women, Charlotte Stoudmire Phd

Dissertations

Black women, ages 45 and older, are disproportionately affected by the HIV/AIDS epidemic. In 2001, Black women comprised 11% of all older women in the United States; however, they accounted for more than 50% of AIDS cases and more than 65% of HIV cases (Winningham et al., 2004). The literature review reflected little research specifically looking at the reason(s) for the increase in HIV in Black women, ages 45 to 60. Furthermore, few research studies focused on HIV patient health beliefs and their experiences in living with HIV. This study was conducted with an ethnography research method coupled with the …

Instrumental Tango Idioms In The Symphonic Works And Orchestral Arrangements Of Astor Piazzolla. Performance And Notational Problems: A Conductor's Perspective, Alejandro Marcelo Drago

Dissertations

Tango performance practices and notational conventions included in the orchestral works of Astor Piazzolla belong in two groups. The first is tango performance manner, or the specific way of rendering the written musical text; and the second is tango special effects, which could be defined as a group of non-traditional (for European music) instrumental techniques specific to tango music. Both groups are part of a performance style that has been poorly systematized, if at all, and kept alive only by means of face-to-face transmission. The purpose of this dissertation is to identify and analyze the challenges that Piazzolla faced while …

A Comparative Analysis Of Poetic Structure As The Primary Determinant Of Musical Form In Selected A Cappella Choral Works Of Gerald Finzi And Benjamin Britten, Andrew Malcolm Jensen

Dissertations

Numerous scholars have identified the relationship linking words and music as the prime factor in the success of both Gerald Finzi's and Benjamin Britten's vocal music. However, few authors provide a satisfactory discussion concerning the specific musical elements used to achieve that success. Those that do, typically focus upon textual/musical correspondences that highlight poetic meaning at the phrase or single word level. Additionally, no known source draws connections between the text-setting practices of these composers. This dissertation seeks to identify the association of text and music on a larger scale: specifically, the influence of poetic structure as the primary determinant …

An Analytical Conductor's Guide To The Satb A Capella Works Of Arvo Part, Kimberly Anne Cargile

Dissertations

Arvo Part (b. 1935) is an Estonian composer whose works include film scores, piano and organ works, chamber music, choral/orchestral works, and unaccompanied choral works. This dissertation is limited to the composer's SATB a cappella works. During an eight-year "period of silence" from 1968 to 1976, Part ceased serious composition in order to find his true compositional "voice." During this hiatus, Part abandoned his Lutheran faith, converting to the Russian Orthodox Church, and discovered a fascination with sacred Medieval and Renaissance music, which had been denied him as a student in the USSR. These events, added to the lingering influence …

First, a series of diacid functional trithiocarbonate chain transfer agents (CTA's) were synthesized and examined for their effectiveness as mediating agents in controlling the polymerization of «-butyl acrylate (nBA). Overall, CTA26 demonstrated good control in the homopolymerization of nBA with respect to the molecular weight and the molecular weight distribution, as well as its ability to form block copolymers with high reinitiating efficiency, and thus was chosen as the CTA for …

The Effects Of Flaxseed Sdg On Perimenopausal Women With Mild Hyperlipidemia, Bonnie Marblestone Phd

Dissertations

In 2001, the National Cholesterol Education Program (NCEP) expanded their guidelines for evaluation and treatment of hyperlipidemia which includes not only a low cholesterol diet and exercise, but also the use of plant stanols such as Flaxseed and Soluble fiber. According to the NCEP III guidelines, women with mild hyperlipidemia and low risk cardiac factors would not qualify for drug therapy to control their cholesterol. However, the use of plant stanols could be used as an alternative. As there are limited studies involving postmenopausal women in regards to treatment of heart disease, there is virtually no information or research on …
