Disassembly Of Actin Structures By Nanosecond Pulsed Electric Field Is A Downstream Effect Of Cell Swelling, Andrei G. Pakhomov, Shu Xiao, Olga N. Pakhomova, Iurii Semenov, Marjorie A. Kuipers, Bennett L. Ibey

Bioelectrics Publications

Disruption of the actin cytoskeleton structures was reported as one of the characteristic effects of nanosecond-duration pulsed electric field (nsPEF) in both mammalian and plant cells. We utilized CHO cells that expressed the monomeric fluorescent protein (mApple) tagged to actin to test if nsPEF modifies the cell actin directly or as a consequence of cell membrane permeabilization. A train of four 600-ns pulses at 19.2 kV/cm (2 Hz) caused immediate cell membrane poration manifested by YO-PRO-1 dye uptake, gradual cell rounding and swelling. Concurrently, bright actin features were replaced by dimmer and uniform fluorescence of diffuse actin. To block the …

Enhancing Understanding Of Discrete Event Simulation Models Through Analysis, Kara Ann Olson

Computer Science Theses & Dissertations

Simulation is used increasingly throughout research, development, and planning for many purposes. While model output is often the primary interest, insights gained through the simulation process can also be valuable. Insights can come from building and validating the model as well as analyzing its behaviors and output; however, much that could be informative may not be easily discernible through these existing traditional approaches, particularly as models continue to increase in complexity.

This research extends current work in model analysis and program understanding to assist modelers in obtaining more insight into their models and the systems they represent. A primary technique …

Mouse Oocyte Maturation And Embryo Development After Exposure To Vemurafenib (Plx4032), An Anti-Melanoma B-Raf V600e Inhibitor, Bo Liu

Theses and Dissertations in Biomedical Sciences

Vemurafenib is a selective B-Raf^V600E inhibitor in melanoma targeted therapy which also inhibits the wild type B- and C-Raf. In oocyte maturation, the C-Raf/MAPK pathway acts as an important self-enhancing and promoting system, w hereas in embryo development, the C-Raf/M APK pathway participates in pre- and post- implantation embryo proliferation and differentiation.

The hypothesis: Vemurafenib has detrimental effects on oocyte maturation and/or embryo development. Mouse oocytes and one cell (1C) mouse embryos were tested by ex vivo culturing with Vemurafenib in serial dilution. Oocytes were evaluated by cell cycle morphology, spindle formation and chromosomal alignment by im munofluorescence (IF) …

The Impact Of Multiple Nursery Areas On The Population Structure Of Atlantic Menhaden, Brevooria Tyrannus, Kristen A. Anstead

OES Theses and Dissertations

Understanding the population structure and patterns of connectivity in marine fishes is essential when making predictions about a species' resiliency and persistence in an increasingly changing environment. The Atlantic Menhaden Brevoortia tyrannus is a clupeid that plays a critical role in the marine food web and supports one of the largest fisheries on the US East Coast. In addition to a decrease in overall numbers and spawning stock biomass, recruitment levels have remained low since the 1990s. Menhaden use numerous estuaries along the Atlantic coast for juvenile development before recruiting to the adult population and the contribution of each of …

Self-Regulating Smoking And Snacking Through Physical Activity., Hwajung Oh, Adrian H. Taylor

Peninsula Medical School

OBJECTIVE: Emotional snacking contributes to weight gain after smoking cessation. Exercise acutely reduces cravings for cigarettes and snack food. This study examined if different exercise intensities acutely reduces snack and cigarette cravings and attentional bias (AB) to video clips of snacks and cigarettes among abstinent smokers. METHODS: Abstinent smokers (and snackers; N = 23) randomly did 15 mins of moderate and vigorous cycling and a passive control in a cross-over design. Visual initial AB (IAB) and maintained AB (MAB) were assessed pre- and after treatment while watching paired snacking/neutral or smoking/neutral video clips. Desire to snack and smoke were assessed …

A Glimpse Into Modem Danish Poetry, Athena Kildegaard

The Bridge

"It is difficult to get the news from poems yet men die miserably every day for lack of what is found there," wrote the American poet William Carlos Williams. In America, getting the news from Danish poets is even more difficult. That's true in part because there are few translators working, but also because there are few publishers interested in translation. Perhaps, if more of us read and bought poetry in translation, this situation might change. And fewer of us will die "for lack of what is found there."

The Influences Of Poultry Litter Biochar And Water Source On Radish Growth And Nutrition, Julia Allen, David E. Longer, Edward E. Gbur, Lichen Hao

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Many row-crop fields today have declined in soil fertility due to poor management practices and overuse of pesticides. Under these conditions, plant nutrient uptake can be sub-optimal. There are several soil amendments that can be used to improve soil quality and plant growth. This study focused on the addition of biochar to the soil and the use of structured water to enhance plant growth. Biochar is produced by pyrolysis of organic feedstocks. Previous studies which focused on biochar have shown an increase in plant yield, nutrient availability in the soil, and soil water holding capacity. Structured water is the liquid …

Palatability Of Teff Grass By Horses, Rachel R. Cummins, Kenneth Coffey, Nancy Jack, Kathleen Jogan, Edward Gbur, Robert Rhein, Dirk Philipp, Melissa Adams, William Smith, Katherine Clayton

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Most forages commonly used to feed horses have potential detriments including blister beetles or excessive fiber concentrations. Teff grass (T), a warm-season annual forage, has the potential to be a good alternative for horses because of its lack of observed disorders. Our objective was to compare preference by horses for T harvested under different conditions with that of bermudagrass (B) harvested at two maturities. Six different forages were evaluated: T harvested at the late vegetative stage (TLV), at late bloom but that incurred 33 mm of rainfall between mowing and baling (TLBR), with caryopsis visible (TES), or at soft dough …

Situational Context, Philosophical Belief, And Moral Constructs: The Multifaceted Nature Of Moral Judgment, Jessie Huang

CMC Senior Theses

Recent studies have shown that different free will beliefs affect moral behavior. The purpose of the current study was to investigate whether different free will beliefs also influence moral judgment. College students (N = 56) were randomly assigned to one of three framing manipulations: free will, determinism, or neutral. They then read three morally questionable scenarios that differed by situational context. Following each scenario, participants completed a moral judgment questionnaire that measured four moral constructs: moral evaluation, moral responsibility, justification, and punishment. Finally, participants completed a Free Will & Determinism Questionnaire (FWD-Q) that measured their lay beliefs in free …

How Corporations Manage Industry And Consumer Expectations Via The Csr Report, Sarah Bonewits Feldner, Kati Tusinski Berg

College of Communication Faculty Research and Publications

With increased stakeholder scrutiny, it is increasingly salient to consider how corporations make the case that their CSR activities are sufficient, appropriate, and successful. The CSR report is the vehicle by which organizations communicate the breadth of activities they engage in to make a difference in society. Using rhetorical analysis and surveys, we argue that the CSR report functions as a means by which corporations manage stakeholder expectations and seek to legitimate corporate behaviors. Our findings indicate that most reports are structured based on external guidelines but include the use of classic rhetorical strategies of ethos, pathos, and logos to …

Contributions Of The Pre-Bötzinger Complex And The Kölliker-Fuse Nuclei To Respiratory Rhythm And Pattern Generation In Awake And Sleeping Goats, Hubert Forster, Joshua M. Bonis, Katie L. Krause, Julie Wenninger, Suzanne Neumueller, Matthew Hodges, Lawrence Pan

Physical Therapy Faculty Research and Publications

We investigated in three groups of awake and sleeping goats whether there are differences in ventilatory responses after injections of Ibotenic acid (IA, glutamate receptor agonist and neurotoxin) into the pre-Bötzinger complex (preBötC), lateral parabrachial (LPBN), medial (MPBN) parabrachial, or Kölliker-Fuse nuclei (KFN). In one group, within minutes after bilateral injection of 10 μl IA (50 mM) into the preBötC, there was a 10-fold increase in breathing frequency, but 1.5 h later, the goats succumbed to terminal apnea. These data are consistent with findings in reduced preparations that the preBötC is critical to sustaining normal breathing. In a second group, …

Chemosensory Receptors In Tsetse Flies Provide Link Between Chemical And Behavioural Ecology, Daniel Masiga, George Obiero, Rosaline Macharia, Paul Mireji, Alan Christoffels

All Peer-Reviewed Publications

Tsetse flies survive in a variety of environments across tropical Africa, often rising to large numbers, despite their low birth rate of one offspring every seven to nine days. They use olfactory receptors to process chemical signals in their environments to find food, escape from predators, and locate suitable larviposition sites. We discuss the identification of odorant and gustatory receptors in Glossina morsitans morsitans and the role genomics could play in management of nuisance insects. © 2014 Elsevier Ltd.

Storage Of Mung Bean (Vigna Radiata [L.] Wilczek) And Pigeonpea Grains (Cajanus Cajan [L.] Millsp) In Hermetic Triple-Layer Bags Stops Losses Caused By Callosobruchus Maculatus (F.) (Coleoptera: Bruchidae), C. M. Mutungi, H. Affognon, A. W. Njoroge, D. Baributsa, L. L. Murdock

All Peer-Reviewed Publications

Dry mung bean and pigeonpea grains that had sustained some insect damage but fumigated before the start of the experiment were stored in triple-layer hermetic bags (Purdue Improved Crop Storage (PICS™ bags) or woven polypropylene (PP) bags for 6 months. Some of the bags were artificially infested with cowpea bruchid Callosobruchus maculatus (F.) (PICS1, PP1) while others were not (PICS0, PP0). In an additional trial, PP bags containing the grains were treated with Actellic Super® dust before being artificially infested (PP1Ac). Moisture content, live adult C.maculatus count, grain damage, weight loss, and seed germination were determined on a monthly basis. …

Aquaporins Are Critical For Provision Of Water During Lactation And Intrauterine Progeny Hydration To Maintain Tsetse Fly Reproductive Success, Joshua B. Benoit, Immo A. Hansen, Geoffrey M. Attardo, Veronika Michalková, Paul O. Mireji, Joel L. Bargul, Lisa L. Drake, Daniel K. Masiga, Serap Aksoy

All Peer-Reviewed Publications

Tsetse flies undergo drastic fluctuations in their water content throughout their adult life history due to events such as blood feeding, dehydration and lactation, an essential feature of the viviparous reproductive biology of tsetse. Aquaporins (AQPs) are transmembrane proteins that allow water and other solutes to permeate through cellular membranes. Here we identify tsetse aquaporin (AQP) genes, examine their expression patterns under different physiological conditions (blood feeding, lactation and stress response) and perform functional analysis of three specific genes utilizing RNA interference (RNAi) gene silencing. Ten putative aquaporins were identified in the Glossina morsitans morsitans (Gmm) genome, two more than …

Connecting Model Species To Nature: Predator-Induced Long-Term Sensitization In Aplysia Californica, Maria J. Mason, Amanda J. Watkins, Jordann Wakabayashi, Jennifer Buechler, Christine Pepino, Michelle Brown, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Previous research on sensitization in Aplysia was based entirely on unnatural noxious stimuli, usually electric shock, until our laboratory found that a natural noxious stimulus, a single sublethal lobster attack, causes short-term sensitization. We here extend that finding by demonstrating that multiple lobster attacks induce long-term sensitization (>= 24 h) as well as similar, although not identical, neuronal correlates as observed after electric shock. Together these findings establish long-and short-term sensitization caused by sublethal predator attack as a natural equivalent to sensitization caused by artificial stimuli.

Speaking And Rhetoric In The Community: The Implications Of Aristotle's Understanding Of Being, Logan C. Vescio

CMC Senior Theses

This thesis analyzes Martin Heidegger's early interpretation of Aristotelian concepts. The goal is to acquire an increased understanding of the ideas underlying Aristotle's political philosophy, as well as those underlying Heidegger's own later philosophy. The investigation begins with a critique of Kantian logic and the assumptions which underlie it, which are ultimately traced back to Aristotle. The passages that pertain to Kant's interpretation are assessed by Heidegger, who concludes that it is speaking, not explicit definition, that grounds possibility for life in a human sense. To demonstrate Heidegger's argument, the thesis transitions into an assessment of the Greek view of …

The Emergence Of Leadership In Children: The Role Of Play, Athletics, And School, Shelby K. Barthold

Leadership studies and leadership development have become increasingly popular in recent years. However, much of this popularity has been focused on leadership in adults. This thesis explores the emergence and development of leadership skills in children as they gain experience from play, athletics, and school. The definition of leadership is examined as well as the skills needed for proficient leadership. The skills are structured around the Big Five personality factors. Each of the areas discussed – play, athletics, and school – gives children many opportunities to interact with their peers allowing for valuable development. Overall, this thesis asserts that leadership …

Analysis Of Character Translations In Film Adaptations Of Popular Literature, Emmanuel Camarillo

CMC Senior Theses

A brief look at the history of film adaptation studies and its terminology. Character differences between a piece of literature and it's film version are compared in three separate case studies. The film adaptations of a graphic novel, a classic novel, and a play are analyzed on the basis of the changes made to specific characters within their respective stories and the effects of those changes on the overall outcome of the film.

Summiting In The Last Wilderness: A Cultural And Environmental History Of Mountaineering In Alaska, Allison M. Barnwell

CMC Senior Theses

Mountaineering is not typically considered an academic subject. Nor is there much scholarship on the sport, let alone its history in the state with the smallest population, Alaska. Yet through analysis of the sport, deeper connections in the relationship between humans and the environment, the history of colonizing both indigenous peoples and land, and the place of gender and sport in Alaska come to light. Mountaineers that traveled to Alaska in the late 19th century and early 20th century were some of the first advocates for protecting its land, yet also displayed their imperialist and masculine values in the mountains. …

Say Goodbye To Hollywood: The Performance Discrepancy Of Franchise Films Between The Domestic And Foreign Box Office, James H. Havlicek

CMC Senior Theses

The increasing globalization of entertainment appears to be having a major impact on the dynamics of the American film industry. The U.S. box office is no longer predominant, meaning that in order to most effectively capitalize on the state of the theatrical market, domestic studios must now more heavily incorporate foreign preferences into production strategy. This study explores the financial nuances of the global box office in relation to sequel-driven film franchises, which have seemingly come to dominate commercial filmmaking as a result of their risk-minimized profitability. We focus on discrepancies between foreign and domestic performance in order to analyze …

The Rise Of Private Equity In China: A Case Study Of Successful And Failed Foreign Private Equity Investments, June Kim

CMC Senior Theses

China's transition from a planned economy to a market economy has brought about remarkably rapid economic growth. Year after year, China boasted of double-digit growth rates since the early 1990s. Attracted by China's so-called "economic miracle," foreign investors began entering the Chinese market hoping to benefit from the country's vast array of financial opportunities. Private equity, particularly a leveraged buyout, was an unfamiliar concept in China until late 1990s. Now China has become the most attractive destination among emerging markets for private equity investment. Global private equity firms are currently raising billions of dollars for funds focusing on China because …

The Deontological And Utilitarian Cases For Rectifying Structural Injustice In Sweatshop Labor Ethics: A Critical Assessment, Clark J. Kissiah

CMC Senior Theses

Sweatshop labor has been condemned by scholars, activists, students and consumers in more developed countries on charges of wrongful exploitation, and a failure to respect the dignity, and basic needs of sweatshop workers. This paper surveys charges against sweatshop labor, and some of the more influential arguments for, and against, rectifying the background structural injustices that perpetuate it. I argue that in certain sweatshop cases, compensating workers below a prima facie morally acceptable level can be most successful in striving towards the duty of beneficence that employers owe to their employees. Therefore, we ought to pursue utility-maximizing acts over others …

The Grand Strategy: A Study On Hannibal’S Stratagem During The Second Punic War, John T. Medin Iv

CMC Senior Theses

In this paper I sought to determine whether or not Hannibal Barca had a grand strategy to deal with the Romans during the Second Punic War. If Hannibal did have a strategy, I would try to determine what his strategy was and if it was actually feasible. I approached this question by looking into the background leading up to the Second Punic War, the primary sources explanation of Hannibal’s strategy during the Second Punic War, the logistical feasibility of the plan, and Hannibal’s movements throughout Italy during the war. In conclusion I decided that Hannibal did have a Grand strategy …

An Analysis Of The Substantive Effectiveness Of The National Environmental Policy Act: Lessons From Ivanpah, Stephanie C. Oehler

CMC Senior Theses

Nearly 45 years ago, the National Environmental Policy Act (NEPA) was signed into law to become the first national policy for the environment of the United States. As it has evolved over time through implementation and litigation, numerous countries and states around the world have emulated NEPA with similar environmental impact assessment requirements. Many scholars have evaluated the success of the legislation in accomplishing its lofty goals. Most commonly, however, these studies address the procedural performance of agencies through the creation of environmental impact statements. This thesis examines the effectiveness of NEPA in accomplishing its substantive, rather than procedural, goals …

CMC Senior Theses

The oil extraction mechanisms of hydraulic fracturing, horizontal drilling, and acidization have recently spread throughout the state of California. This thesis explores and assesses whether federal and state legislation should approve of fracking operations in California after studying its effects on human health, the environment, and the economy. This thesis assesses the impacts of fracking; analyzes the role of current legislation and regulation; compares California fracking to fracking in other states and countries; and provides recommendations for future action.

Fate Of Antimicrobials And Antimicrobial Resistance Genes In Simulated Swine Manure Storage, Stacey R. Joy, Xu Li, Daniel D. Snow, John Gilley, Bryan L. Woodbury, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions. First-order decay rates were determined for each antibiotic with half-lives ranging from1 day (chlortetracycline) to 10 days (tylosin). ARGs were monitored in the swine manure slurry, and losses of approximately 1 to 3 orders of magnitude in relative abundance were observed during the 40 day storage period. First-order degradation profiles were observed for chlortetracycline and its corresponding resistance genes, tet(X) and tet(Q). Tylosin was degraded to approximately 10% …

On Moral Supervenience, Ramon Alvarado

Open Access Theses & Dissertations

Conventional accounts of moral supervenience are not fit for the moral realist to use against skeptic objections. In particular, they do not provide a sufficiently robust account of dependence or determination needed to counter the argument from queerness.This is shown in their inadequacy to deal with cases of minimal discernibility and cases of moral gradation. A similarity-base account of supervenient seems to be the one that the moral realist ought to incorporate instead.
