Radiation resistance studies of amorphous silicon films

Hydrogenated amorphous silicon thin films were irradiated with 2.00 MeV helium ions using fluences ranging from 1E11 to 1E15 cm(-2). The films were characterized using photothermal deflection spectroscopy and photoconductivity measurements. The investigations show that the radiation introduces sub-band-gap states 1.35 eV below the conduction band and the states increase supralinearly with fluence. Photoconductivity measurements suggest the density of states above the Fermi energy is not changing drastically with fluence

Moving feelings, intimate moods and migrant protest in Cardiff

In a public mood of marked hostility around asylum, emotion overflows protest media produced as part of recent migrant mobilisations. Protest media seeks to touch audiences, to stir public feeling for migrants, to build a sense of collectivity, and to move the collective to action, but the emotional modes used also work sideways to produce uneasy and unpredictable affects. This article examines the ‘cultural politics of emotion’(Ahmed 2004) in three pieces of media produced as part of recent refugee protests in Cardiff, Wales: a book of asylum-seeking women’s testimonies, a series of antideportation blog posts and videos, and a ‘Refugee House’ museum installation. Feelings declared outright, such as love, rage and despair, work to move publics outright, but also relegate participants into confined genres of action and subjectivity. Uneasy effects generated through the media’s aesthetics and materiality stir up other, more ambivalent and mobile emotional modes. This article explores the qualities of these uneasy affects, and how they might alter moods around asylum for political effect

Annealing characteristics of irradiated hydrogenated amorphous silicon solar cells

It was shown that 1 MeV proton irradiation with fluences of 1.25E14 and 1.25E15/sq cm reduces the normalized I(sub SC) of a-Si:H solar cell. Solar cells recently fabricated showed superior radiation tolerance compared with cells fabricated four years ago; the improvement is probably due to the fact that the new cells are thinner and fabricated from improved materials. Room temperature annealing was observed for the first time in both new and old cells. New cells anneal at a faster rate than old cells for the same fluence. From the annealing work it is apparent that there are at least two types of defects and/or annealing mechanisms. One cell had improved I-V characteristics following irradiation as compared to the virgin cell. The work shows that the photothermal deflection spectroscopy (PDS) and annealing measurements may be used to predict the qualitative behavior of a-Si:H solar cells. It was anticipated that the modeling work will quantitatively link thin film measurements with solar cell properties. Quantitative predictions of the operation of a-Si:H solar cells in a space environment will require a knowledge of the defect creation mechanisms, defect structures, role of defects on degradation, and defect passivation and annealing mechanisms. The engineering data and knowledge base for justifying space flight testing of a-Si:H alloy based solar cells is being developed

Dirty pretty language: translation and the borders of English

This article analyses the politics of English, and translation into Englishness, in the film Dirty Pretty Things (Frears). With a celebrated multilingual cast, some of whom did not speak much English, the film nevertheless unfolds in English as it follows migrant characters living illegally and on the margins in London. We take up the filmic representation of migrants in the “compromised, impure and internally divided” border spaces of Britain (Gibson 694) as one of translation into the imagined nation (Anderson). Dirty Pretty Things might seem in its style to be a kind of multicultural “foreignized translation” which reflects a heteropoetics of difference (Venuti); instead, we argue that Dirty Pretty Things, through its performance of the labour of learning and speaking English, strong accents, and cultural allusions, is a kind of domesticated translation (Venuti) that homogenises cultural difference into a literary, mythological English and Englishness. Prompted by new moral panics over immigration and recent UK policies that heap further requirements on migrants to speak English in order to belong to “One Nation Britain” (Cameron), we argue that the film offers insights into how the politics of British national belonging continue to be defined by conformity to a type of deserving subject, one who labours to learn English and to translate herself into narrow, recognizably English cultural forms. By attending to the subtleties of language in the film, we trace the pressure on migrants to translate themselves into the linguistic and mythological moulds of their new host society

Thermodynamic properties in the normal and superconducting states of Na(x)CoO(2)*yH(2)O powder measured by heat capacity experiments

The heat capacity of superconducting Na(x)CoO(2)*yH(2)O was measured and the data are discussed based on three different models: The thermodynamic Ginzburg-Landau model, the BCS theory, and a model including the effects of line nodes in the superconducting gap function. The electronic heat capacity is separated from the lattice contribution in a thermodynamically consistent way maintaining the entropy balance of superconducting and normal states at the critical temperature. It is shown that for a fully gapped superconductor the data can only be explained by a reduced (about 55 %) superconducting volume fraction. The data are compatible with 100 % superconductivity in the case where line nodes are present in the superconducting gap function.Comment: Revised, 19 pages, 3 figure

Vocal Velocity: A Strategic Public Relations Plan for the Contemporary A Cappella Society of America

The Contemporary A cappella Society of America (CASA) is a not-for-profit organization whose mission is, “to foster and promote contemporary a cappella music around the world through education, recognition, and the creation of performance opportunities.” In order to fulfill this mission, CASA must develop and maintain fruitful relationships with two key publics: a cappella groups and a cappella fans. My Honors capstone will be two-tiered, including a short-term public relations strategy aiming to strengthen the organization\u27s relationship with a cappella groups, along with a long-term strategy to increase its recognition and presence in the world of a cappella fans. The people of CASA work primarily as volunteers, which means that their “PR strategy is admittedly somewhat piecemeal,” according to CASA\u27s Communications & Public Relations volunteer director, Matt Emery (M. Emery, personal communication, September 14, 2011). Most non-profit organizations do not have the time or resources to develop a research-based strategic outreach plan. My project assists them by developing a strategic public relations plan for CASA, based on primary research on two of its key publics
