Dartmouth Scholarship

Transmission of HIV-1 during breastfeeding is a significant source of new pediatric infections in sub-Saharan Africa. Breast milk from HIV-positive mothers contains both cell-free and cell-associated virus; however, the impact of breast milk on HIV-1 infectivity remains poorly understood. In the present study, breast milk was collected from HIV-positive and HIV-negative Tanzanian women attending antenatal clinics in Dar es Salaam. Milk was analyzed for activity in vitro against both cell-free and cell-associated HIV-1. Potent inhibition of cell-free R5 and X4 HIV-1 occurred in the presence of milk from all donors regardless of HIV-1 serostatus. Inhibition of cell-free HIV-1 infection positively …

Vers Une Ecocritique Postcoloniale Africaine: L’Environnement Dans Les Litteratures Africaines De Langue Française, Marie Chantale Mofin Noussi

Foreign Languages & Literatures ETDs

This work was motivated by two major facts: the African environment is at the heart of the continents relationships with colonialism, neocolonialism and globalization; but there is not enough literary emphasis on this environmental centrality. This work contributes in bridging the gap between African Francophone Literatures and the environmental discourses. This dissertation is the literary analysis of the representation, the transformation, and the exploitation of the African environment in the operating policies of colonial, neocolonial and global power structures. These environmental policies in the colonial and current global world tend to mold the African environment in a way that the …

Students' Perceptions Of The Use Of Peer-To-Peer Esl Text Chat: An Introductory Study, Dale Arthur Garratt

Language, Literacy, and Sociocultural Studies ETDs

Thousands of international ESL students come to the United States every year to learn English for the purpose of matriculating into an American university. Teaching these diverse students can be a challenge for educators and despite the students significant investment of time and money, many of them are inadequately prepared for the demands of university work. Text chat has been studied by some scholars as a means of assisting ESL students to write more effectively. However, greater understanding is needed of the affective experiences and perceptions of students toward peer-to-peer ESL text chat. That is the thrust of this study, …

Efl To Esl: A Case Study Of University International English L2 Students In Transition, Michael W. Schwartz

Language, Literacy, and Sociocultural Studies ETDs

This is a case study of four international English L2 students transitioning from their home countries into the academic context of a US university. It investigates the intersections of identity and investment as English L2 students interact with English resources, and how proficiency may or may not mitigate the type and quality of access to English resources. Furthermore, the study proposes a learner as agent framework for understanding the processes of gaining access to English resources. Finally, the study argues that proficiency is a complex issue that needs to be analyzed and defined locally rather than globally and that decontextualized …

Surfactant Incorporated Nanostructure For Pressure Drop Reduction In Oil And Gas Lines [Div], Sudipta Seal, Sameer Deshpande, Paul Jepson, Suresh Kuiry, Patil Swanand

UCF Patents

Nano-sized rare earth metal oxide particles are prepared from aqueous reverse micelles. The engineered nanoparticles have large surface area to volume ratios, and uniformly incorporate a surfactant in each particle, so that when applied to the inner surface of a pipeline or sprayed onto a fluid stream in a pipeline, the particles reduce the roughness of the inside surface of pipe being used to transport fluid. The application of a nanolayer of this novel nanoceria mixture causes a significant reduction in pressure drops, friction, and better recovery and yield of fluid flowing through a pipeline.

The Visual Exchange: The Intersection Of Vision, Gender, And Empire In Nineteenth-Century British Literature, Stacey L. Kikendall

English Language and Literature ETDs

This dissertation examines key moments in fictional and autobiographical texts when gender construction and colonization intersect and create the possibility for reciprocal visual exchange between disparate people. In a visual exchange, the participants actively and meaningfully look at one another, at the same time acknowledging the others subjectivity. I argue that these moments hint at the subliminal utopian desire by the author, and perhaps the reader, for a more equal, even democratic, community. I study a range of texts written during the long nineteenth century by male and female authors, including Sydney Owenson's The Wild Irish Girl (1806), The History …

The synthesized LiFePO₄/C composite was in pure phase of olivine-type, …

Electrochemical Performances Of Layered Polypyrrole/Chemically Reduced Graphene Oxide Nanocomposites As Supercapacitor Electrodes, Si-Zhe Xu, Xue-Jiao Zhou, Kun Wu, Yong-Qiang Yang, Hai-Xia Wu

Journal of Electrochemistry

Nanocomposites of polypyrrole (Ppy) and chemically reduced graphene oxide (CRGO), Ppy/CRGO, have been fabricated through in-situ polymerization of pyrrole on graphene oxide (GO) sheets. The as-synthesized Ppy/CRGO composites were characterized complementarily using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and Fourier transformed infrared spectroscopy (FT-IR). By controlling the initial ratio of the GO to pyrrole, the layered composites could be obtained and their thickness could be tuned properly. The Ppy/CRGO electrodes were prepared using a mechanical compressing technique and their electrical conductivity and electrochemical properties were characterized systematically. We demonstrated that as electrodes for supercapacitor, the Ppy/CRGO composites with Ppy …

Electrochemical Corrosion And Protection Of Copper Foil Treated By Surface Siloxane Filming, Wei-Jun Miao, Yu-Bao Zhang, Ning-Yu Gu, Feng Liu

Journal of Electrochemistry

Copper foil specimens were immersed in hydro-alcoholic solution of 3-amino-propyl-trimethoxy-silane (γ-APS) to prepare a protective self-assembled siloxane membrane on the surface. Potentiodynamic polarization and electrochemical impedance spectroscopic tests were performed in 0.1 mol.L^-1 NaCl to evaluate the effects of the self-assembled siloxane membranes prepared at different pH of γ-APS on corrosion of copper foil. The surface morphology of siloxane membrane was studied by SEM. Experimental results revealed that the γ-APS self-assembled siloxane membranes effectively inhibited the corrosion of copper foil and the optimum anti-corrosion effect was found when the pH value of the silane solution was 7.

Electrochemical Immunosensor Based On Polycalconcarboxylic Acid Modified Electrode For The Determination Of Alpha-Fetoprotein, Xiao Lin, Shao-Huang Weng, Jian-Zhang Zhou, Ai-Lin Liu, Xin-Hua Lin, Yong-Ji You

Journal of Electrochemistry

A highly sensitive electrochemical immunosensor based on novel electropolymerized polycalconcarboxylic acid modified electrode (poly-CCA/GC) has been fabricated for the detection of alpha-fetoprotein (AFP). The differences of the poly-CCA/GC electrodes before and after the immobilization of AFP antibody were characterized via scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The immobilization of antibody/antigen/antibody-HRP sandwich was formed on the poly-CCA modified electrode for the determination of special AFP concentrations. The electrochemical signals generated from the HRP which catalyzed the TMB substrate were measured. Experiment results indicated that the developed immunosensor showed a good sensitivity and precision.

Electrocatalytic Activities Of Mb/Aunps/Mwnts/Gc Electrode For Hydrogen Peroxide Reduction, Zheng-Juan Huang, Hua-Ping Peng, Dai-Jun Cha, Ai-Lin Liu, Wei Chen, Xin-Hua Lin, Yong-Ji You

Journal of Electrochemistry

Using myoglobin (Mb) as a model, the direct electrochemistry of the immobilized proteins on the AuNPs/MWNTs composite was studied. The results showed that the AuNPs/MWNTs composite can maintain the bioactivity and facilitate the direct electrochemistry of Mb in the Mb/AuNPs/MWNTs/GC electrode. Based on the direct electron transfer of the immobilized Mb, the protein electrode exhibited excellent electrocatalytic activity to the reduction of H₂O₂ with a linear range …

Identification Of The Functional Binding Pocket For Compounds Targeting Small-Conductance Ca2+-Activated Potassium Channels, Miao Zhang, John M. Pascal, Marcel Schumann, Roger S. Armen, Ji-Fang Zhang

Pharmacy Faculty Articles and Research

Small- and intermediate-conductance Ca2+-activated potassium channels, activated by Ca2+-bound calmodulin, play an important role in regulating membrane excitability. These channels are also linked to clinical abnormalities. A tremendous amount of effort has been devoted to developing small molecule compounds targeting these channels. However, these compounds often suffer from low potency and lack of selectivity, hindering their potentials for clinical use. A key contributing factor is the lack of knowledge of the binding site(s) for these compounds. Here we demonstrate by X-ray crystallography that the binding pocket for the compounds of the 1-EBIO class is located at the calmodulin-channel interface. We …

Exploring The Iron Triangle: Predicting Student Success At A Large Rural Community College, Clint Ewell

Teacher Education, Educational Leadership & Policy ETDs

The Iron Triangle is the belief that Access, Cost, and Quality are linked in such a way that to change one, we must change one or both of the others. For example, to expand Access, some leaders in higher education believe that they must, by definition, either increase Costs or decrease Quality. Winston has proposed an economic model for higher education which states that Price = Costs - Subsidies. In this model, Price is what students pay to colleges to attend classes, while costs are the expenses incurred by colleges to provide those classes. Subsidies come from a variety of …
