Sensitivity Of Cellular Oxidative Damage To Biosynthetic Rate And Metabolic Rate, Palihawadana Walauwe Kamalika Kaushalya Amunugama

Masters Theses

"The relationship between energy expenditure and longevity is a long standing question in aging studies. The empirical results have contradictory effects on the existing theories. A theoretical model and an experimental test of it were presented, revealing the detailed tradeoffs between metabolic rate, biosynthetic rate and cellular damage level. The dissipative mechanisms of oxidative metabolism cause various forms of cellular damages. To counteract the accumulation of damage, organisms have evolved highly efficient maintenance mechanisms. If there is no other energy demand possess, then most of the cellular damage would be repaired, regardless of how metabolic rate varies. However, the repairing …

"Accurately detecting and classifying vesicle-plasma membrane fusion events in fluorescence microscopy, is of primary interest for studying biological activities in a close proximity to the plasma membrane. In this paper, we present a novel Gaussian mixture model for automated identification of vesicle-plasma membrane fusion and partial fusion events in total internal reflection fluorescence microscopy image sequences. Image patches of fusion event candidates are detected in individual images and linked over consecutive frames. A Gaussian mixture model is fit on each image patch of the patch sequence with outliers rejected for robust Gaussian fitting. The estimated parameters of Gaussian functions over …

A Force Feedback Haptic Interface For Atomic Force Microscopy, Abdulmohsen Alabdulmuhsin

Masters Theses

"Integrating a force feedback haptic device with atomic force microscopy (AFM) improves the capability to investigate and manipulate the objects on a micro- and nanoscale surface. The haptic device provides the researcher with a sense of touch and movement by changing the position of the stylus or amount of force on it. The developed system's concept is to provide the user a sense and feel and control of the AFM probe at the nanoscale. By positing the haptic stylus, the user generates reference to commands to the AFM probe. In turn, forces experienced by the probe are communicated to the …

Mr4rf: Mem-Device With Impedance And Their Usage With Impedance Matching Networks For Passive Rfid Tags In The Uhf, George H. Harris

Masters Theses

"The passive RFID tag in the UHF has been employed in several different applications including, tracking, logistics, and as a sensing platform for the Internet of things (IoT). The tag is ideal for this industry due to its unique design. It harvests all of its energy from the environment, and is small, cheap, and requires little to no maintenance. However, there are two major issues limiting the potential of the passive RFID systems: the limited power harvested by the tag, and the high susceptibility to interference and coupling. In particular, dynamic environments render the traditionally fixed, RF impedance matching network …

Discrete-Time Neural Network Based State Observer With Neural Network Based Control Formulation For A Class Of Systems With Unmatched Uncertainties, Jason Michael Stumfoll

Masters Theses

"An observer is a dynamic system that estimates the state variables of another system using noisy measurements, either to estimate unmeasurable states, or to improve the accuracy of the state measurements. The Modified State Observer (MSO) is a technique that uses a standard observer structure modified to include a neural network to estimate system states as well as system uncertainty. It has been used in orbit uncertainty estimation and atmospheric reentry uncertainty estimation problems to correctly estimate unmodeled system dynamics. A form of the MSO has been used to control a nonlinear electrohydraulic system with parameter uncertainty using a simplified …

Bridging In Vi Tro & In S Il Ico Techniques: Uncovering The Structural Characteristics And Light-Dependent Modifications Of The Light-Response Btb Proteins In Arabidopsis Thaliana, Nicholas Reitz

Masters Theses

The conjugation of the NEDD8 protein has been found to cause a wide range of changes to the overall function of a protein. The addition of NEDD8 to a conserved lysine on Cul proteins has been found to provide Cul with increased flexibility, while the transcription factor protein p53 was prevented from binding to DNA after NEDD8 conjugation. Using Arabidopsis thaliana, we investigated the potential conjugation of NEDD8 to the AtLRB1 and AtLRB2 proteins, which are both members of Cul3-RING E3 Ubiquitin Ligase complexes, using both in vitro and in silico techniques. The AtLRBs are negative regulators of the red …

Researching The Historical Representations Of Ancient Egypt In Trade Books, Lieren Schuette

Masters Theses

State and national education initiatives require that historical information be introduced in the classroom through the utilization of multiple diverse texts. The role of non-fiction in the English/language arts classroom, as well as informational texts in the history/social studies classroom, increased considerably. The use of trade books allows teachers to connect the two curricula, while also meeting the standards. Primary sources can assist in filling the informational gap left by trade books and textbooks, which allow students to gain a more balanced view of historical events. Teachers, however, are not given direction as to which specific curricular materials are most …

Political Intolerance In The 21st Century: The Role Of Ideology And Emotion In Determining Intolerant Judgments, Matthew Cain

Masters Theses

Decades of research in Social Psychology have demonstrated that political intolerance is not displayed equally with respect to ideology. In particular, conservatives and those with right-wing beliefs are much more likely to display intolerant judgments than those with liberal or left-wing beliefs. This "prejudice gap" has been found to be so ubiquitous that it is now the conventional wisdom regarding the relationship between ideology and intolerance. However, a small, but growing literature challenges this presumed ideological asymmetry and has instead found that liberals and conservatives display intolerance under certain circumstances. Synthesizing the recent research showing ideological symmetry in intolerance judgments, …

From Trade Deficit In Goods To Trade Surplus In Services: An Eclectic And Extended Gravity Model Approach In Analyzing The Determinants Of Service Trade Of The United States, Tofayel Ahmmad

Masters Theses

This paper employs an eclectic and extended gravity model of trade to assess the most important determinants of real export and import of services of the United States by analyzing US service trade with its 33 partner countries for 15 years. Distance affects US real export of services negatively, but has no influence on US real import of services. A devaluation of the US dollar increases service export of the United States. We find a positive relationship between US goods trade and US service exports. US outward FDI has a positive impact on US real export of services, but has …

The four academic enablers identified by DiPerna and Elliott (2000) and measured by the Academic Competence Evaluation Scales (DiPerna & Elliott, 2000) include engagement, interpersonal skills, motivation, and study skills. A wealth of literature has detailed the critical importance of academic enablers to academic success, as well as identified specific ways which teachers can instruct students in development of these skills. While DiPerna and Elliott (2000) note that teachers' perceptions of the importance of these skills and related behaviors can assist in informing intervention for individual …

Effects Of Treated Wastewater Effluent On Microbial Community Structure In A Natural Receiving Aquatic System, Matthew D. Hladilek

Masters Theses

Despite our dependency on treatment facilities to condition wastewater for eventual release to the environment, our knowledge regarding the effects of treated water on the local watershed is extremely limited. Responses of these lotic systems to the treated wastewater effluent have been traditionally investigated by examining the benthic macroinvertebrate assemblages and community structure; however, these studies do not address the microbial diversity of the water systems. In the present study, planktonic and benthic bacterial community structure were examined at fourteen sites (from 60 m upstream to 12,100 m downstream) and at two time points along an aquatic system receiving treated …

Same-Sex Peer Influence On Female Undergraduate Body Image Perception, Caitlyn Buchanan

Masters Theses

Regardless of age, race, or socioeconomic class, women throughout western cultures are well documented for having body image related insecurities. These insecurities can be the result of pressure to look and behave a certain way from a variety of sources including media and peers. This study explored the role that same-sex peers play in undergraduate women's perception of body image. Four undergraduate women at a public, Midwestern university who lived within campus housing were interviewed. Results of the study showed that same-sex peers did not play a significant role in the women's perception of body image. The results of this …

Written Discourse Performance After Blast Injury, Brittany M. Loomis

Masters Theses

A blast injury (BI) is caused by a wave from a bomb which damages organs, specifically the brain. Once soldiers/veterans have sustained a BI, they will most likely present with a cognitive-communication deficit resulting from the traumatic brain injury. Language related symptoms are most apparent in written language skills due to the high level of cognitive function required for writing. This study investigated written discourse skills following a BI. Written discourse samples were collected from four participants and four controls. A description of the Butcher Picture from the Aphasia Diagnostic Profile was analyzed for productivity, efficiency, and local and global …

Predictive Power Of Aggregate Accounting Earnings Growth For Growth Of Future Gdp, Meng Huang

Masters Theses

Konchitchki and Patatoukas (2014a) suggest that aggregate accounting earnings growth is a significant leading indicator of future nominal Gross Domestic Product (GDP) growth in the United Sates, and that earnings growth adds power to contemporaneous GDP growth in predicting future GDP growth. The future GDP growth used in their model is based on the third estimate of GDP for a given quarter, which is released by the U.S. Bureau of Economic Analysis (BEA) three months after the end of the quarter. My study is also centered on predictability of future GDP growth but it provides a useful extension of the …

Gendered Pathways To Office For Members Of The 112th U.S. House Of Representatives, Samantha Sarich

Masters Theses

Research both asserts that there is a particular path through careers in either business or law that many political candidates take to Congress and that female candidates do not always follow this standard path. Female candidates have been found to emerge from a wider array of experiences outside of business and law. Differences in pathways male and female candidates take to public office have been widely studied, yet little attention has been focused on whether or not female candidates having experience serving on the board of a non-profit organizations can be a part of a viable alternate pathway to public …

In order to assess the impact of the lessons, fruit and vegetable plate waste were gauged prior to and …

The Art Of Voluntelling: Research On Mandated And Altruistic Volunteers, Tyler Kalahar

Masters Theses

A comparison of mandated and altruistic volunteers that completed community service hours was conducted. Participants were enrolled at a mid-sized, mid-Western university. T-test and correlational analysis were conducted on data gathered through the Community Service Attitudinal Scale (2000). The data was used to compare and contrast the characteristics of mandated and altruistic volunteers. Mandated volunteers (M = 5.73, SD = 1.40) reported feeling like they were not making as much of an impact performing community service compared to altruistic volunteers (M = 6.61, SD = 1.17) at significance level (t(72) = 2.88, p< 0.01). Altruistic (M=6.25, SD=1.35) …

Comparison Of Agency And Volunteer Stream Assessments Using Macroinvertebrate Assemblages, David William Petry

Masters Theses

Professional stream assessments can be both time and cost intensive. Many states have developed citizen science programs in an effort to provide reliable data to supplement agency assessments. To test how two of these protocols and their conclusions compare, I sampled 16 sites in seven streams within east central Illinois using techniques from two different organizations: Illinois RiverWatch and Illinois Environmental Protection Agency. Overall, spring RiverWatch, fall RiverWatch, and fall IEPA sampling all produced unique results and conclusions. Compared to fall IEPA assessments, spring RiverWatch was affected by differences in both sampling protocol and season. RiverWatch sampling in fall reduced …

Breaking The Chains Of Trafficking: An Educational Program, Amanda K. Feder

Masters Theses

With popular television shows and films focusing on the issue of sex trafficking, many discursive constructions of the issue allow for a "script" to be followed and replicated in many anti-trafficking discourses. Ultimately, the constructions of the issue become a basis of understanding on sex trafficking, which can consequentially limit the availability and accuracy of anti-trafficking resources. From examining popular discourses and their construction of sex trafficking on a global and U.S. scale, to creating an educational program designed for college-level courses on the realities of trafficking, this project focuses on de-bunking the myths of sex trafficking on a local …

Dysfunctional Text Messaging As Related To Social Anxiety, Self-Esteem, Emotional Intelligence, And Attentional Control, Sean E. Nelson

Masters Theses

Despite the widespread and increasing use and popularity of text messaging since the mid 1990's, the extent of the psychological literature regarding this technology is scarce. Chief amongst these underexplored areas is the relationship that text messaging, as a mode of Nonverbal Asynchronous Communication, has with Verbal Synchronous Communication abilities. For this study, these abilities have been operationalized as social anxiety, self-esteem, emotional intelligence, and attentional control. The available research implies a relationship between these concepts. Despite mostly theoretical links in the literature, no study had attempted to measure many of these relationships empirically. This study examined the relationship between …

Contextual Conditions Related To The Undergraduate Experience And The Nature Of Alumni Involvement: A Qualitative Study, Kasey G. Evans
