Application Of Electrospray Ionization Mass Spectrometry For Ionic Liquids And Their Biodegradation Products, Sepideh Rahbarirad

Masters Theses

Ionic liquids (ILs) are organic salts with unique physico-chemical properties and are used as green alternatives to volatile organic solvents. ESI-MS is a sensitive technique to detect these stable, permanent ions. My research focused on (1) Identification of biodegradation products of ionic liquids and (2) Multiplexed tandem MS by modulation of ionization efficiency.

Studies, have demonstrated that ILs are toxic to the environment, which makes their biodegradability an important consideration. In this work, metabolites generated during the biodegradation of 1-butyl-3-methylimidazolium chloride (BMIM), a degradation resistant and commonly used ionic liquid, are identified using high performance liquid chromatography-mass spectrometry (LC-MS).

The Role Of Sexual Self-Disclosure In Partner Relational Satisfaction And Uncertainty, Riley Richards

Masters Theses

Sexual communication and sexual self-disclosure (SSD) are often viewed as taboo and uncomfortable when discussed between sexual partners. Prior research has demonstrated a strong connection between SSD and other relational factors in current dating and married partners. To that end, this study uses an Actor-Partner Independence Model (APIM) with current cross-sex sexual and romantic partners to understand how emergent adults experience SSD and the role it plays in their relational satisfaction and uncertainty. Social Penetration Theory (Altman & Taylor, 1973) undergirds this study as a theoretical foundation in fleshing out the ways emergent adults self-disclose about their sexual lives to …

Slug Tests In Unconfined Aquifers, Rozkar Izzaddin Ismael

Masters Theses

This research presents a hydraulic conductivity (K) analysis of unconfined aquifers using slug tests. Slug tests are used to determine in situ aquifer hydraulic conductivity more quickly and economically than by a pump test. This study examines how to best conduct a slug test using a physical slug. Different common slug test analysis methods are compared, including Bouwer and Rice (1976), Hvorslev (1951), Dagan (1978) and Kansas Geological Survey (KGS, 1994). Questions that motivated this study include: Which methods are better for performing and analyzing slug tests? Does the size of the physical slug affect the results? Do large initial …

Targeting Interventions To Reduce Chlamydia-Related Disparities In Kalamazoo County Using Gis And Statistical Analysis, Claudio Owusu

Masters Theses

The annual incident rates of chlamydia continue to rise within Kalamazoo County despite an increase in public health campaign, particularly for persons between the ages of 15-24. This trend in incidence rates of chlamydia by age also shows strong disparities in race/ethnicity and gender at state and county levels. With the increasing burden on the cost of treatment of chlamydia, which is one of the many sexually transmitted infections, targeting high risk populations offers a means of reducing the cost and the spread of the infection. This has shaped attention of researchers and policy makers to the complexity of the …

Extent Of Capillary Rise In Sands And Silts, Rachel Lynn Salim

Masters Theses

The values reported in literature for the height of capillary rise in fine sands, silts, and clays are contradictory. Most of the values were based on mathematical models, which used estimated rather than measured input data. This work measured capillary rise values in laboratory experiments in fine-grained sands and silts.

Two uniform sands with grains 0.35--0.7 mm in diameter and 0.3-0.6 mm in diameter, silt with an average grain size below 40 microns, and 0.35--0.7 mm sand coated with a water-repellant spray were carefully packed into two-inch diameter glass columns. These columns were placed into clear plastic tanks with water …

Investigating Student Approaches To Learning With Structured Or Unstructured Client Collaboration, Cara E. Masselink

Masters Theses

As a profession, occupational therapists pride themselves on providing client-centered treatment. It is hypothesized that increased structured client collaboration as well as incorporating reflective journaling in the fieldwork setting (to meet the students at their level of learning) will improve student's critical thinking skills, and encourage them to seek deeper learning techniques to ensure they are providing 'best practice' occupational therapy for the client and his/her family. In this pilot study, the learning approaches of students in two existing University-based clinic programs were measured over the course of one semester. The treatment group was required to participate in structured, intentional …

Political Utopias Of The Renaissance: An Analysis Of Thomas More’S Utopia, Johann Valentinus Andreae’S Christianopolis, And James Harrington’S The Commonwealth Of Oceana, Brittany Page Brake

Masters Theses

Utopian works have entertained generations throughout history. Much like more recent genres including science-fiction novels or movies, utopian works stimulate the mind and ultimately cause its readers to question whether an author’s design of such a place, or society, is possible in the real world. While some may perceive the purpose of utopias to be completely fantasy-driven, there is a great deal of scholarly literature that dedicates itself to proving otherwise. More specifically, many scholars argue that utopias are serious and practical, ultimately aimed at re-shaping the entire political structure of a society.

This thesis aims to understand the more …

Environmental Applications Of Chromatography-Mass Spectrometry, Wisam Abdulabbas Flayyih Al Isawi

Masters Theses

Gas chromatography-mass spectrometry (GC-MS) and liquid chromatographymass spectrometry (LC-MS) are powerful analytical techniques that combine the separation power in a stationary phase with the detection power of mass spectrometry. GCMS and LC-MS have gained dominant positions in identifying and quantifying different analyte species due to their high selectivity, high sensitivity, and high reproducibility.

My research utilizes the analytical power of LC-MS and GC-MS to address two environmental issues: 1) Identification of biodegradation products of the ionic liquid 1- butyl-3-methylimidazolium chloride (BMIMCl) by an activated sludge microbial community using LC-MS and 2) identification and quantification of polycyclic aromatic hydrocarbons (PAHs) in …

The Value Of The Arts In Education, Thorin Teague

Masters Theses

Art is a subject that has no substitute, as the learning and production of art satisfies a uniquely human need to communicate and connect with other human beings. The marriage of art and society can (and should) be thought of as culture. This author intends to assert that the arts have a critical place in education and indeed human society itself, bringing ancillary benefits to bear on the subject without relying on them as the primary justification for the retention and even expansion of arts programs; education (which could in turn be thought of the dissemination of cultural knowledge) of …

Shifting Gears Of Safety: Women Truck Drivers Experience Added Safety Concerns Over The Road, Stephanie A. Sicard

Masters Theses

Of the over 500,000 professional truck drivers within the United States, only six percent are women. Ten in-depth interviews focus on the safety issues that women truck drivers face over1 the road. Stereotypical masculine norms are encouraged in male dominated fields, and it is when stereotypical masculinity is endorsed that sexual harassment and assault is much higher. I argue that women truck drivers are forced into a double-bind situation in which they attempt to make themselves visible as equals, while simultaneously hiding themselves for safety. I aim to not only broaden the understanding of the issues faced by professional women …

Geochemical And Petrological Characterizations Of Peridotite And Related Rocks In Marquette County, Michigan, Andrew Lloyd Sasso

Masters Theses

This study characterizes the following rock units in Marquette County, Michigan in terms of geochemistry and petrology: (1) Presque Isle Peridotite, (2) Deer Lake Peridotite, (3) Yellowdog Peridotite, and (4) Black Rock Point Gabbro. Analyses were conducted to determine if any petrological or geochemical relationships exist between these units, and to assess the potential of these units to host magmatic sulfide deposits.

The generated data and chosen geotectonic proxies indicate that Black Rock Point Gabbro and Deer Lake Peridotite crystallized from unrelated magmas, probably during the formation of the Great Lakes Tectonic Zone (2.7-1.85 Ga). No evidence was found which …

Strengthening Tier 1 Elementary Reading Within A Multi-Tiered System Of Support, Carla N. Osborn

Masters Theses

Training teachers about the foundational reading skills is an important step in creating students who are proficient readers. However, training is not enough. Teachers need support through instructional coaching. Even with coaching support, sustainability of these practices will be a challenge if systems are not in place throughout the district to support ongoing implementation. By combining the processes of creating a Multi-Tiered System of Support, reading training, and instructional coaching, sustainability of practices can be possible. Research does not currently exist as to whether the combination of these efforts has increased student achievement in reading at the elementary level. This …

A Feasibility Study To Develop A Missions Training Center To Recruit African-American Young Adults For Global Missions Through Education And Training, Linda Saunders

Masters Theses

African-Americans have too long been disengaged from global missions; they represent less than one half of one percent of all global missionaries. Re-engaging the African-American church community in global missions can be accomplished by recruiting African-American young adults to participate in global missions by way of a global missions training center focused on education and training. For the African-American church to become engaged in global missions there are a myriad of obstacles to overcome; namely, the lack of global missions education and training within the African-American church community. While obstacles exist, they are not insurmountable. The key components for engaging …

Changes In The Eeg Spectrum Of A Child With Severe Disabilities In Response To Power Mobility Training, Nadina Zweifel

Masters Theses

Literature suggests that self-generated locomotion in infancy and early childhood enhances the development of various cognitive processes such as spatial awareness, social interaction, language development and differential attentiveness. Thus, having access to a power mobility device may play a crucial role for the overall development, mental health, and quality of life of children with multiple, severe disabilities who have limited motor control. This study investigates the feasibility of using electroencephalography (EEG) as an objective measure to detect changes in brain activity in a child due to power mobility training. EEG data was collected with a modified wireless neuroheadset using a …

Formula 1 racing is one of the most advanced technological sports. The aerodynamic on open wheel race cars is essential for the performance during a race. The front wing on a race car produces about 30 percent of the entire downforce of a race car. Several studies on front wings for open wheel race cars are conducted by various authors. A number of research studies include single element airfoils in ground effect and undisturbed flow. Numerical and experimental studies show that by decreasing the ground clearance, the downforce increases. The most efficient ground clearance is reported to be approximately 10 …

Investigating Ph Banding Kinetics Of Chara Corallina In Alternating Light Conditions With Rectangular Pulse Voltammetry, Matthew C. Zandee

Masters Theses

Chara corallina is an important biological model due to its large internodal cells, the simple shape, and the wide range of techniques that can be used to study it. The alternating acidic and basic banding pattern of Chara corallina upon illumination has been studied and well described over the past several decades. However, much of this complex mechanism is not fully understood. Few studies have shown how the acidic and basic regions have responded in real time as lighting conditions change. Utilizing rectangular pulse voltammetry (RPV) and pH-sensitive carbon microelectrodes along the cell wall allows for a real time profile …

The Effect Of Seasonal Fish Migration On Energy Budgets In Two Coastal Michigan Streams, Emily M. Dean

Masters Theses

Migratory fish are known to seasonally enter coastal stream systems but the magnitude of the effects these migrations have on stream energy budgets is not fully understood. The Laurentian Great Lakes have several introduced and native adfluvial fish, where only a few studies have investigated the impacts of their migration on energy budgets in Michigan coastal streams. We quantified the contribution of energy from Chinook salmon (Oncorhynchus tshawytscha) muscle and eggs, steelhead (Oncorhynchus mykiss) eggs, and larval white suckers (Catostomus commersonii) to coastal stream energy budgets. Energy densities and energy delivered to streams were estimated using bomb calorimetry and annual …

Coming Home: How Identity Plays A Role In Students Who Study Abroad In An Area That Is Representative Of Their Heritage, Mariana I. Naddaf

Masters Theses

Study abroad participation has more than tripled over the past two decades in the United States and has led to increased research efforts on topics such as the benefits of study abroad and the development of students who study abroad; however, little research exists on students who have heritage connections to the area in which they study abroad. In order to address this need within the field of higher education and study abroad, a hermeneutic phenomenological qualitative study was conducted to explore what factors, if any, affect changes in identity salience for students who study abroad in areas that are …

Retaining Staff Members Of Color At A Midwestern Predominantly White Institution, Tiffany L. Steele

Masters Theses

There continues to be a gap between the growing multicultural student body and predominantly White faculty and staff members who work with students. One factor in increasing the likelihood of persistence in college for minoritized students is the presence of a mentor with a similar ethnic background. Nevertheless, as of 2004, the populations of faculty, staff and administrators are still disproportionately dominated by White Americans. This study investigated how a university or college can better retain staff members of color. The participants were current and past staff members of color who worked at one university within the Midwestern United States. …

Categorization Of Food Value Via Crayfish Aggression, Justin Thanh-Tuan Tran

Masters Theses

In numerous species, social interactions play a key role in deciding the allocation of resources. Aggression is a tactic that crayfish utilize to become dominant, which allows them to acquire higher quality resources. Many studies of aggression and agonistic interactions have used crayfish because they are known to be innately aggressive and are quick to become involved in agonistic interactions that may escalate into fighting. The primary objective of this study is to elucidate the relationship between differing food resources and their effect on aggression of crayfish. It is hypothesized that increased desirability for the food resource will induce more …

Becoming Self: A Jungian Approach To Paradise Lost, Geoffrey Kishbaugh

Masters Theses

When addressing Paradise Lost, the reader is not encountering static characters but is interacting with and being acted upon by highly symbolic manifestations of the primitive condition of humanity‟s collective psyche. In dealing with the figures of Christianity‟s mythos, John Milton creates a text that stimulates the collective unconscious of the reader and draws out the primordial expressions of the self—archetypal manifestations. Subsequently, these manifestations are projected back onto the figures within the text and the reader engages in a dynamic relationship with the poem as both the reader and the figures of Adam and Eve experience the process of …

Registration And Segmentation Of Multimodality Images For Post Processing Of Skeleton In Preclinical Oncology Studies, Vineeth Radhakrishnan

Masters Theses

Advancements in medical imaging techniques provide biomedical researchers with quality anatomical and functional information inside preclinical subjects in the fields of cancer, osteopathic, cardiovascular, and neurodegenerative research. The throughput of the preclinical imaging studies is a critical factor which determines the pace of small animal medical research. The time involved in manual analysis of large amount of imaging data prior to data interpretation by the researcher, limits the number of studies in a time frame.

In the proposed solution, an automated image segmentation method was used to segment individual vertebrae in mice. Individual vertebrae of MOBY atlas were manually segmented …

Bsent From The Body, Present With The Lord: A Traditional Evangelical Critique Of Traditional Roman Catholic And Non-Traditional Evangelical Teachings Regarding Purgatory, Thomas Gentry

Masters Theses

Traditional Roman Catholic theology and certain non-traditional expressions of evangelical theology teach that Christians who die without realizing perfect holiness will enter into a postmortem state called purgatory for the purpose of preparing them to behold the beatific vision of God in heaven. The purpose of this work is to refute these teachings by proving that they are unbiblical. The procedure for doing is to first summarize the traditional Roman Catholic teaching of purgatory; second, present interpretations of select biblical and apocryphal texts related to purgatory from the pro-purgatory perspective, followed by a traditional evangelical response; third, present a four-fold …

The Gĩkũyũ Mũtũrĩrũ: Preserving A Piece Of Kenya's Agrarian Past Through Flute Music, Jennifer Larue

Masters Theses

The Agĩkũyũ people of Kenya are one of the largest people groups in Kenya. However, systematic repression of Gĩkũyũ culture led to many traditional elements being forgotten, put aside, if not lost completely. The mũtũrĩrũ, a bark flute used when herding and in certain ritual dances, was one such element. The mũtũrĩrũ was initially a temporary instrument, which evolved into more permanent bamboo versions. These may have between two and six finger holes. Another version, called a "spider web mũtũrĩrũ" has no finger holes but has a paper membrane over one end to create a buzzing timbre effect. Research was …
