Formation of helium spectrum in solar quiescent prominences

We present new non-LTE modelling of the helium spectrum emitted by quiescent solar prominences. The calculations are made in the frame of a one-dimensional plane-parallel slab. The physical parameters of our models are the electron temperature, the gas pressure, the slab width, the microturbulent velocity and the height above the solar surface. In this paper, we present isothermal isobaric models for a large range of temperature and pressure values. This work brings considerable improvements over the calculations of Heasley and co-workers (Heasley et al. 1974, Heasley and Milkey 1976, 1978, 1983) with the inclusion in our calculations of partial redistribution effects in the formation of the HI Lyα, Lyβ, HeI λ 584 Å and HeII λ 304 Å lines. In addition we consider detailed incident profiles for the principal transitions. The statistical equilibrium equations are solved for a 33 bound levels (HeI and HeII) plus continuum atom, and the radiative transfer equations are solved by the Feautrier method with variable Eddington factors. In this way we obtain the helium level populations and the emergent line profiles. We discuss the influence of the physical parameters on the helium level populations and on the main helium spectral lines. The effect of helium abundance in the prominence plasma is also studied. Some relations between singlet and triplet lines are given, as well as between optically thin or thick lines, HeI and HeII lines, and between the HeI λ 5876 Å and HI λ 4863 Å lines. In a future work this numerical code will be used for the diagnostic of the prominence plasma by comparing the results with SUMER observations

Upper-class women reading celebrity news : audience reception study on celebrity news viewed through the lens of class

The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Title from PDF of title page (University of Missouri--Columbia, viewed on November 17, 2009).Thesis advisor: Dr. Yong Volz.M.A. University of Missouri--Columbia 2009.This research attempts to understand the reception of celebrity news magazines among upper class women in the U.S. The ultimate goal of this research is to identify cultural repertoires about the consumption and use of celebrity news. These repertoires are compared to ones found in Joke Hermes (1995) study on British tabloid readers. Qualitative research methods provide the framework for this study and in-depth interviews were conducted in order to collect detailed data. Data was collected from the interviews and analyzed for common themes and repertoires. I found most of the subjects read celebrity news with resistance to its dominant message. In fact, most readers negotiated the text and imprinted their own meanings onto it. Celebrity news permeates nearly all media outlets and has seen a recent surge of popularity and press time over the past ten years. Understanding what attracts readers to celebrity news is useful information for media scholars and professionals. A more intimate understanding of how women use celebrity news also helps to illuminate how being a celebrity newsreader affects women's lives.Includes bibliographical references

Any Shape or Form: An Online Module for Teaching Medical Students Citation Management in Residency Settings

Objective: To describe how the library’s online tutorial for medical students, “Introduction to Citation Management Tools,” was created and integrated into the College of Medicine’s Residency Preparation Boot Camp. Implemented in 2017, passing the tutorial is still a requirement for completing the boot camp. Methods: In 2017, the Maguire Medical Library was asked by undergraduate and graduate medical education faculty to create a citation management tutorial for 4th-year medical students preparing to commence their respective residency programs. As part of the College of Medicine’s Residency Preparation Boot Camp, the tutorial needed to provide students with an overview of citation management tools that could be used at a variety of different institutions depending on access and availability. Two librarians created an online tutorial with content presented in slides that contained text and video, and that were organized by topic. A hands-on section was incorporated for students to practice using Zotero, a free citation management tool. To assess student knowledge of slide content, students must correctly answer questions after each section; questions could be retaken until passed. The tools used for creating the module included Springshare’s LibWizard tool, Camtasia and Snagit for screen recordings and screenshots, and Canva for graphics and images. Each year, new content has been added to the module based on feedback from faculty, students, and other users. Results: From 2017 to 2019, there have been 444 submissions. Since data collection and analysis for program improvement is ongoing, remaining results will be presented during the poster session. Conclusions: Online tutorials can be a positive educational and interactive way to learn about citation management tools. For the future, we hope to continue refining and adapting the current tutorial as needed, while exploring additional opportunities to use this technology in other subject areas

The modelling of the solar upper photosphere and lower chromosphere based upon ATM data

Spectral data obtained by the SO82B experiment aboard SKYLAB were used to critically evaluate existing models of the solar upper photosphere and lower chromosphere. These spectral diagnostics were used to develop new solar models

2D non-LTE radiative modelling of He I spectral lines formed in solar prominences

The diagnosis of new high-resolution spectropolarimetric observations of solar prominences made in the visible and near-infrared mainly, requires a radiative modelling taking into account for both multi-dimensional geometry and complex atomic models. Hereafter we contribute to the improvement of the diagnosis based on the observation of He I multiplets, by considering 2D non-LTE unpolarized radiation transfer, and taking also into account the atomic fine structure of helium. It is an improvement and a direct application of the multi-grid Gauss-Seidel/SOR iterative scheme in 2D cartesian geometry developed by us. It allows us to compute realistic emergent intensity profiles for the He I 10830 A and D3 multiplets, which can be directly compared to the simultaneous and high-resolution observations made at THeMIS. A preliminary 2D multi-thread modelling is also discussed.Comment: 6 pages, 9 figures, A&

Young people’s views concerning their voice in Education, Health and Care planning meetings: A participatory Q-study

A recent Code of Practice (DfE & DoH, 2015) for working with children and young people (YP) described as having special educational needs and disabilities (SEND) has been published in the UK. It extends the rights of children and YP and their parents, to have a say in their education and demands greater collaboration between agencies. This research explores the experiences of YP described as having SEND participating in Education, Health and Care (EHC) planning meetings. It focusses particularly on ideas around the voice of the child. • What are young people’s views concerning their voice in Education, Health and Care planning meetings? • What are the implications of young people’s views concerning their voice in Education, Health and Care planning meetings for Educational Psychology Practice? The study included 21 YP aged between 11 and 19. To limit the reliance on language skills (Hughes 2016), Q-methodology has been used to support them to think about their experience. Q-methodology offers statements encompassing the range of things YP might say about having a say in EHC planning meetings and asks participants to arrange them based on how much they agree or disagree with the statements. The research is participatory in that young people were involved in the study as co-researchers and helped to develop and pilot the statements. The study found that despite many similarities in participants’ descriptions of meetings, there was considerable variation in how YP experienced them. Some expressed having little or no voice while others had some level of voice. Implications for Educational Psychology practice and possible future directions for research are discussed

Autonomy in the Institution: An Institute for Detroit Techno and Rave Culture

The institution, in physical form, requires spatial and visual separation to replace its socio-economic history in the urban and physical landscape. An Institute for Detroit Techno will test this assertion through the establishment of techno music as an autonomous art form and the manipulation of the physical context of the project through collage and situating the project along the freeway, which is an autonomous spatial condition within the city

Atomic layer deposition of Zn(O,S) thin films with tunable electrical properties by oxygen annealing

Zinc oxysulfide, Zn(O,S), films grown by atomic layer deposition were annealed in oxygen to adjust the carrier concentration. The electron carrier concentration of Zn(O,S) can be reduced by several orders of magnitude from $10^{19}$ to $10^{15} cm^{−3}$ by post-deposition annealing in oxygen at temperatures from 200 °C to 290 °C. In the case of Zn(O,S) with S/Zn = 0.37, despite the considerable change in the electron carrier concentration, the bandgap energy decreased by only ∼0.1 eV, and the crystallinity did not change much after annealing. The oxygen/zinc ratio increased by 0.05 after annealing, but the stoichiometry remained uniform throughout the film.Chemistry and Chemical BiologyEngineering and Applied Science
