Effect of thermodynamics on ion mixing

Ion mixing of elemental 4d-5d metallic bilayers at 77 K by 600 keV Xe + + ions has been studied to test the validity of the phenomenological model of ion mixing that predicts a dependence on the chemical heats of mixing, DeltaHmix, and on the cohesive energies, DeltaHcoh, of the bilayer elements. A series of samples was chosen to minimize the variation in kinematical properties between samples while maximizing the variation in heats of mixing. The experimental results agree well with the model's predictions, and the experimentally determined constants K1=0.034 Å and K2=27 agree with those of previous work

Drag Incorporated: The Homonormative Brand Culture of \u3ci\u3eRuPaul\u27s Drag Race\u3c/i\u3e

This thesis argues RuPaul’s Drag Race (RPDR, 2009–) positions itself as a homonormative pathway to LGBTQ+ social inclusion through privileging neoliberal selfbranding and commodity activist practices that reify privileged raced, classed, and sexuality identity markers. Utilizing interdisciplinary and intersectional cultural studies methods to conduct a textual analysis, I examine how RPDR produces homonormative LGBTQ+ identities through the commodification and standardization of drag cultures. In conversation with existing RPDR scholars, I critically survey RPDR’s gender biases and prosocial messaging as an example of brand culture’s reification of hegemony and homonormativity within LGBTQ+ communities. This research considers the utility of media representation in identity, community, and political composition while also engaging with how consumption can communicate personal and relational meaning. RPDR proves the homonormative commodification of niche drag cultures perpetuates existing power imbalances, simultaneously benefitting and hindering aspects of the LGBTQ+ rights movement. In effect, RPDR rejects a radical queer politic and commodifies its cultural and iconographic elements, while the brand’s homonormative privileging exacerbates inequalities within LGBTQ+ communities

End-point Estimates and Multi-parameter Paraproducts on Higher Dimensional Tori

Analogues of multi-paramter multiplier operators on R^d are defined on the torus T^d. It is shown that these operators satisfy the classical Coifman-Meyer theorem. In addition, L log L and L (log L)^n end-point estimates are proved.Comment: This is the author's dissertation from Cornell University. 141 pages, 0 figure

THIS IS NOT A TREND

ABSTRACT Workman, Michael, B.F.A., May 2015 Art THIS IS NOT A TREND Faculty Mentor: Elizabeth Dove This is not a trend is a multi-media art installation that examines the valuation system of contemporary art by creating an absurd situation that mimics a real commercial experience. The manner in which value is placed on art is artificial. Both the monetary and intellectual value of art is decided mostly on the reputation of the artist, their fame, and how well their work is marketed to the public. These characteristics are marketed to art consumers in order to sell them an authentic “art” experience. They are being sold the idea that they can be in the presence of genius; whether the art speaks to them or not is irrelevant, anything the artist touches becomes precious and valuable. Art making then becomes more about celebrity than thought. I am interested in analyzing the idea that an artwork’s value is directly attributed to who the artist is and how well they have established their genius. I address these concerns by creating a multimedia art experience that utilizes these marketing tactics in order to sell the viewer my unique touch as a commercial product. I distill the touch into its most basic and literal form, the finger, in order to disingenuously suggest that all artistic value resides within the unique touch of the finger. Each finger is a plastic resin cast of my right index finger. They are sold for $1.00 out of a vending machine. The unique value of my artistic touch is dismantled through its overt replication and sale. An infomercial manipulates the viewer into buying this product. While a series of art works with fingers mounted highlight the disconnect between the stated goals of some contemporary art and its relative ineffectiveness at commenting on complex social issues. By employing the same tactics used by advertisers I attempt to ultimately sell my touch as a useless consumer product, meant to be bought and tossed aside

Correlation between the cohesive energy and the onset of radiation-enhanced diffusion in ion mixing

A correlation between the cohesive energy of elemental solids and the characteristic temperature Tc for the onset of radiation-enhanced diffusion during ion mixing is established. This correlation enables one to predict the onset of radiation-enhanced diffusion for systems which have not yet been investigated. A theoretical argument based on the current models of cascade mixing and radiation-enhanced diffusion is provided as a basis for understanding this observation

ADAP Faculty Needs Assessment for Improvement of Resident Instruction

The research reported in this publication provides an examination of the inservice training needs for Land Grant faculty in the U.S. affiliated Pacific region. It was conducted to prioritize the topics in a series of "Symposia for the Imporvement of Resident Instruction" under the Agricultural Development of the American Pacific (ADAP) initiative. These inservice training events were presented in 1991 based upon the results herein.Funded through the US Department of Agriculture Cooperative Extension Service

Remodelling of human atrial K+ currents but not ion channel expression by chronic β-blockade

Chronic β-adrenoceptor antagonist (β-blocker) treatment in patients is associated with a potentially anti-arrhythmic prolongation of the atrial action potential duration (APD), which may involve remodelling of repolarising K+ currents. The aim of this study was to investigate the effects of chronic β-blockade on transient outward, sustained and inward rectifier K+ currents (ITO, IKSUS and IK1) in human atrial myocytes and on the expression of underlying ion channel subunits. Ion currents were recorded from human right atrial isolated myocytes using the whole-cell-patch clamp technique. Tissue mRNA and protein levels were measured using real time RT-PCR and Western blotting. Chronic β-blockade was associated with a 41% reduction in ITO density: 9.3 ± 0.8 (30 myocytes, 15 patients) vs 15.7 ± 1.1 pA/pF (32, 14), p < 0.05; without affecting its voltage-, time- or rate dependence. IK1 was reduced by 34% at −120 mV (p < 0.05). Neither IKSUS, nor its increase by acute β-stimulation with isoprenaline, was affected by chronic β-blockade. Mathematical modelling suggested that the combination of ITO- and IK1-decrease could result in a 28% increase in APD90. Chronic β-blockade did not alter mRNA or protein expression of the ITO pore-forming subunit, Kv4.3, or mRNA expression of the accessory subunits KChIP2, KChAP, Kvβ1, Kvβ2 or frequenin. There was no reduction in mRNA expression of Kir2.1 or TWIK to account for the reduction in IK1. A reduction in atrial ITO and IK1 associated with chronic β-blocker treatment in patients may contribute to the associated action potential prolongation, and this cannot be explained by a reduction in expression of associated ion channel subunits
