Effects Of Aquatic Acidification On Calcium Uptake In White River Shrimp Litopenaeus Setiferus Gills, Maria-Flora Jacobs

UNF Graduate Theses and Dissertations

Previous research regarding aquatic acidification has examined the protonation of the carbonate and does not consider calcium to be a limiting factor. This is the first study to suggest that pH may affect the uptake of calcium in crustacean gills. This project describes ion transport mechanisms present in the cell membranes of white river shrimp Litopenaeus setiferus gill epithelium, and the effects of pH on the uptake of calcium by these means. Partially purified membrane vesicles (PPMV) of shrimp gills were prepared through a homogenization process that has been used previously to define ion transport in crab and lobster gill …

Generation Z'S Positive And Negative Attributes And The Impact On Empathy After A Community-Based Learning Experience, Amanda Nicole Moscrip

UNF Graduate Theses and Dissertations

Generation Z, also known as the iGeneration, iGenners, GenZ, and Generation Now, consists of those born in the mid-1990s through the late 2010s. Historical events important for this generation have influenced their perception of safety as well as how they interact with others. As compared to previous generations, technological advances (i.e., Smartphones, social media) changed how GenZ communicates, socializes, and receives information. Unique experiences and attributes influenced Generation Z’s empathy because living through these events and seeing their impact changes how they can understand and take the perspective of others. The relation between three factors was examined across University students …

Experimental Analysis Of Protective Headgear Used In Defensive Softball Play, John Scott Strickland

UNF Graduate Theses and Dissertations

Every year in the United States, an estimated 1.6 to 3.8 million people sustain sports-related traumatic brain injuries (TBIs), with an appreciable number of these injuries coming from the sport of softball. Several studies have analyzed the impact performance of catcher’s masks within the context of baseball; however, virtually no studies have been performed on fielder’s masks within the context of softball. Thus, the main objective of the present work was to evaluate the protective capabilities of softball fielder’s masks. To better understand the injury mechanisms and frequency associated with softball head/facial injuries, epidemiological data from a national database was …

An Fmri Exploration Of Information Processing In Electronic Networks Of Practice, Thomas O. Meservy, Kelly J. Fadel, C. Brock Kirwan, Rayman D. Meservy

Faculty Publications

Online forums sponsored by electronic networks of practice have become an important source of information for individuals seeking solutions to problems online. However, not all information available in a forum is helpful or accurate, requiring knowledge seekers to evaluate and filter the solutions they encounter. Most forums offer contextual cues to help knowledge seekers make evaluation decisions, yet little is understood about the cognitive processes and neural mechanisms that underlie how information on these forums is filtered and evaluated. This paper draws on literature in cognitive neuroscience and NeuroIS to develop exploratory research questions about the role of both content …

Moral Development In Business Ethics: An Examination And Critique, Kristen Bell Detienne, Carol Frogley Ellertson, Marc-Charles Ingerson, William R. Dudley

Faculty Publications

The field of behavioral ethics has seen considerable growth over the last few decades. One of the most significant concerns facing this interdisciplinary field of research is the moral judgment-action gap. The moral judgment-action gap is the inconsistency people display when they know what is right but do what they know is wrong. Much of the research in the field of behavioral ethics is based on (or in response to) early work in moral psychology and American psychologist Lawrence Kohlberg’s foundational cognitive model of moral development. However, Kohlberg’s model of moral development lacks a compelling explanation for the judgment-action gap. …

Unclogging The Pipeline: Advancement To Full Professor In Academic Stem, Helga Van Miegroet, Christy Glass, Ronda R. Callister, Kimberly Sullivan

Detecting Soil Macrofauna Using Ground-Penetrating Radar, Melanie N. Stock, David J. Hart, Nicholas J. Balster

Plants, Soils, and Climate Faculty Publications

Fossorial amphibians spend up to ten months belowground, but research into this critical habitat has been impeded by a lack of noninvasive detection methods. Ground-penetrating radar (GPR), however, offers a promising tool because amphibians have theoretically strong electromagnetic (EM) contrasts relative to the soil matrix, and thus potentially high detectability. The objectives of this study were to (1) evaluate GPR by (2) experimentally-inducing three soil thermal regimes that promote stratification in the burrowing depths of 15 Eastern American Toads (Anaxyrus americanus americanus) during the winter of 2011–2012 in Madison, WI, USA. We calculated reflectability and established the unique …

Analysis Of Spermatogenesis In Young Male Hybrids Bred From Domestic Cattle(Bos Taurus) And European Bison (Bison Bonasus), Andrzej Zyczynski, Marta Kloch, Wanda Olech

Turkish Journal of Veterinary & Animal Sciences

A new attempt was undertaken to check the reproductive capabilities of male hybrids bred from European bison (Bison bonasus) and domestic cattle (Bos taurus). The analysis concerned two hybrids aged 1.5?2.5 years (the latter being sampled twice at 6-month intervals), and additionally one 1.5-year-old backcross hybrid. Examination of testicular tissue revealed halting of spermatogenesis, which was hardly ever able to proceed further than meiosis I. Spermatogenesis was arrested at the stage of spermatogonia and primary spermatocytes. Spermatozoa were found only in the case of one hybrid and these were mostly malformed. To summarize, all the males studied were sterile, despite …

Tax Experimentation, Michael B. Abramowicz

GW Law Faculty Publications & Other Works

Random experiments could allow the government to test tax policies before enactment into general law. Such experiments can be revenue-neutral, with the tax authority ensuring ex post that average tax revenues received from taxpayers in the treatment and control groups are equal. Taxpayers might thus volunteer even for experiments that would broaden the tax base, for example by eliminating deductions. Continued participation by taxpayers in such experiments would indicate that the proposed reforms are efficient at least if externalities are disregarded. Non-revenue-neutral experiments raise greater concerns about horizontal inequity, but may be helpful in addressing questions about effects of tax …

Graphene Nanoflake Uptake Mediated By Scavenger Receptors, Fatima Alnasser, Valentina Castagnola, Luca Boselli, Margarita Esquivel-Gaon, Esen Efeoglu, Jennifer Mcintyre, Hugh Byrne, Kenneth A. Dawson

Articles

The biological interactions of graphene have been extensively investigated over the last 10 years. However, very little is known about graphene interactions with the cell surface and how the graphene internalization process is driven and mediated by specific recognition sites at the interface with the cell. In this work, we propose a methodology to investigate direct molecular correlations between the biomolecular corona of graphene and specific cell receptors, showing that key protein recognition motifs, presented on the nanomaterial surface, can engage selectively with specific cell receptors. We consider the case of apolipoprotein A-I, found to be very abundant in the …

Vibrational Characterization Of Granulosa Cells From Patients Affected By Unilaterial Ovarian Endometriosis: New Insights From Infrared And Raman Microspectroscopy, Valentina Notarstefano, Giorgia Gioacchini, Hugh Byrne, Carlotta Zaca, Eleni Sereni, Lisa Vaccari, Andrea Borini, Oliana Carnevali

Articles

Endometriosis is a chronic gynaecological disease characterised by the presence of endometrial cells in extra-uterine regions. One of the main factors impacting on the fertility of women affected by endometriosis is the poor oocyte quality. Granulosa Cells (GCs) regulate oocyte development and maintain the appropriate microenvironment for the acquisition of its competence; hence, the dysregulation of these functions in GCs can lead to severe cellular damages also in oocytes. In this study, luteinized GCs samples were separately collected from both ovaries of women affected by Unilateral Ovarian Endometriosis and analysed by infrared and Raman microspectroscopy. The spectral data were compared …

Articles

A methodology is proposed, based on Raman spectroscopy coupled with multivariate analysis, to determine the Limit of Detection (LOD) and Limit of Quantification (LOQ) for therapeutic drug monitoring in human serum, using the examples of Busulfan, a cell cycle non-specific alkylating antineoplastic agent, and, Methotrexate, a chemotherapeutic agent and immune system suppressant. In this study, ultrafiltration is employed to fractionate spiked human pooled serum to efficiently recover the drug in the filtrate prior to performing Raman analysis. The drug concentration ranges were chosen to encompass the recommended therapeutic ranges and toxic levels in patients. Raman spectra were collected from the …

Improved Performance Of Near Infrared Excitation Raman Spectroscopy Using Reflective Thin-Film Gold On Glass Substrates For Cytology Samples, Sinead Barton, Kevin O'Dwyer, Marion Butler, Hugh Byrne, Luke O'Neill, Bryan M. Hennelly

Articles

Confocal near-infrared Raman spectroscopy has been shown to have applications in the area of clinical biology. A source wavelength in the near infrared is preferred over visible wavelengths for inspecting biological samples due to superior wave number resolution and reduced photo damage. However, these excitation sources have a number of drawbacks when compared to lasers in the visible wavelength region, including the requirement to use expensive highly pure crystal substrates such as Raman grade calcium fluoride as well as long acquisition times due to the lower Raman scattering efficiency. This paper investigates the use of a reflective substrate comprising a …

Numerically Modelling Time And Dose Dependent Cytotoxicity, Hugh Byrne, Marcus A. Maher

Articles

Dose-response curves are fundamental tools of in vitro toxicology, extensively employed in toxicant or drug screening. They are expressed by a variety of end-points and assays, measured at different time-points in a choice of cell-lines, but are typically quantified only using the mean concentration for 50% response (e.g. drug efficacy or pathway inhibition) as an indicator of overall effect. However, the response is the result of a complex and dynamic cascade of events which occur between the initial exposure and the measured end-point, and the characteristic rates of the contributing stages govern the dose response and ultimately the measured characteristic …
