X ray imaging microscope for cancer research
No full textThe NASA technology employed during the Stanford MSFC LLNL Rocket X Ray Spectroheliograph flight established that doubly reflecting, normal incidence multilayer optics can be designed, fabricated, and used for high resolution x ray imaging of the Sun. Technology developed as part of the MSFC X Ray Microscope program, showed that high quality, high resolution multilayer x ray imaging microscopes are feasible. Using technology developed at Stanford University and at the DOE Lawrence Livermore National Laboratory (LLNL), Troy W. Barbee, Jr. has fabricated multilayer coatings with near theoretical reflectivities and perfect bandpass matching for a new rocket borne solar observatory, the Multi-Spectral Solar Telescope Array (MSSTA). Advanced Flow Polishing has provided multilayer mirror substrates with sub-angstrom (rms) smoothnesss for the astronomical x ray telescopes and x ray microscopes. The combination of these important technological advancements has paved the way for the development of a Water Window Imaging X Ray Microscope for cancer research

Enhanced colour encoding of materials discrimination information for multiple view dual-energy x-ray imaging
No full textThis thesis reports an investigation into dual-energy X-ray discrimination techniques. These techniques are designed to provide colour-coded materials discrimination information in a sequence of perspective images exhibiting sequential parallax. The methods developed are combined with a novel 3D imaging technique employing depth from motion or kinetic depth effect (KDE). This technique when applied to X-ray images is termed KDEX imaging and was developed previously by the university team for luggage screening applications at security checkpoints. A primary motivation for this research is that the dual-energy X-ray techniques, which are routinely incorporated into ‘standard’ 2D luggage scanners, provide relatively crude materials discrimination information. In this work it was critical that robust materials discrimination and colour encoding process was implemented as the sequential parallax exhibited by the KDEX imagery may introduce colour changes, due to the different X-ray beam paths associated with each perspective image. Any introduction of ‘colour noise’ into the resultant image sequences could affect the perception of depth and hinder the ongoing assessment of the potential utility of the dual-energy KDEX technique. Two dual-energy discrimination methods have been developed, termed K-II and W-E respectively. Employing the total amount of attenuation measured at each energy level and the weight fraction of layered structures, a combination of the K-II and the W-E techniques enables the computation and extraction of a target objects’ effective atomic number (Zeff) and its surface density (ρS) in the presence of masking layers

The Center for Ray Bradbury Studies: A Case Study in Sustaining a Single Author Archive
No full textIndiana University-Purdue University Indianapolis (IUPUI)The Center for Ray Bradbury Studies (cited also as the “Bradbury Center” or the “Center”) is a single author archive, museum, and outreach center housed in the Institute for American Thought, located in the School of Liberal Arts at IUPUI. This dissertation employs a case study methodology to explore the complex issue of single author archive management and sustainability as it applies to the Bradbury Center by extending the research process beyond working with primary sources and published materials.
The applied research project unfolded in two phases. The first involved an intensive four-day on-site consultation in which five professional archivists and preservation experts from across the Midwest visited the Bradbury Center and examined its collections and policies. Following their visit, the consultants prepared recommendations concerning artifacts, manuscripts, correspondence, physical layout, access, operational procedures, processing priorities, and environmental/climate control for artifacts. The on-site consultation team also informed objectives, goals, and strategies for addressing the preservation needs of the Center’s vast and varied collections, aiding in systematically moving forward with curatorial initiatives, and planning for general organizational development.
The second research phase involved site visits to five peer institutions to tour facilities, interview directors and archivists about best practices, and established a plan for adapting these practices to the Bradbury Center. Findings from both research phases inform the Bradbury Center’s immediate and long-term plans for center staff, fundraising, spatial expansion and renovation, and the Center’s strategy for identifying key constituencies as it endeavors to serve a broad spectrum of public and academic audiences through various outreach and programming initiatives.
Upon completion of the case study field research, a formal report was prepared. That report serves as the cornerstone for this applied dissertation. Additional chapters cast a vision for the Bradbury Center and address potential opportunities to serve the Indianapolis region by tapping into tourism markets, conventions, and local cultural festivals and celebrations while also developing into an international research hub as the sole entity that preserves the material legacy of Ray Bradbury. The introductory chapter situates the Bradbury Center within the legacy of the central figure of the Center—Ray Bradbury

Dear Mr. Kephart:
I thought you would be interested
in knowing that your story "Afoot and Awing in
the Great Smokies", published in the January
issue, was chosen by a committee of judges of
the Franklin Square Agency, which is owned by
Harper Brothers, as one of the ten best stories
of the month.
With the best of the holiday greetings,
I am
Sincerely yours,

Diffuse X-ray scattering from tropomyosin crystals
No full textMotions in proteins are often an important part of their function. Structural information about the protein is hence incomplete without an understanding of the protein dynamics. X-ray crystallography is the technique used in the majority of protein structure determinations; from a crystallographic standpoint as well, the movement of the molecules in the crystal which profoundly affect the X-ray scattering are important. All motions in the crystal affect the Bragg scattering and also give rise to diffuse scattering between and surrounding the Bragg spots. The diffuse X-ray scattering may comprise a large part of the total scattering from the crystal, and it contains information about the correlation of motions that is not available from analysis of the Bragg diffraction peaks.Tropomyosin is a muscle protein that is involved in control of the muscle contraction process. Changes in the structural conformation of the protein are an essential part of this process. Tropomyosin crystals exhibit striking diffuse scattering patterns which are related to its inherent flexibility and motions in the crystal. Diffuse scattering data along all the major directions of the crystal have been measured. A complete three-dimensional diffuse scattering data set has been simulated, and this has been compared to the experimental data in the measured directions. A combination of empirical and analytical methods were used to perform the simulations, and the amplitudes, directions and correlation distances of the motions within the crystal have been calculated.Made available in DSpace on 2011-05-07T13:26:11Z (GMT).

Publishing Lolita. Comment on the Preface of John Ray, Jr., Ph.D.
No full textThis paper discusses the “act” of publishing in the broad sense as a “process” in stages that considers the education and the linguistic skills of the writer, runs the production, the printing and the distribution of the book, makes use of strategies to avoid censorship and judicial prosecution, and monitors the critics and the publics’ reaction to the book; the main point of this paper, however, is the analysis of the acts of publishing and of writing as they are mentioned or hinted at in the story itself or as they are interwoven in the fictional reality. Then, beginning with a comment on the Preface of Lolita, by John Ray, Jr. ph. D., the fictional authors present argumentative strategies for the non banning of the book and point out relevant aspects of the intricate relationship between, on one hand, John Ray and Humbert Humbert, two writers who are immanent in the narrative web, and, on the other hand, the signatory author, Vladimir Nabokov, bringing out, among other issues, the awareness of the boldness of his literary bet against the readership of the “middle-class nosy era” as well as of its confidence in the promising results of Lolita’s publication
