    Notes: Ion-ion coincidence measurements following K-shell absorption in the carbon dioxide molecule were performed by applying time-of-flight mass spectrometry in conjunction with monochromatic synchrotron radiation and electron impact. Identification of particularly sensitive electronic transitions and the consecutive molecular fragmentation in real time was performed. Analysis of coincidence recordings from decomposition of carbon dioxide reveals one distinct pathway in which three cations are formed following excitation of oxygen Is electrons.

    Topics: Physics
    Notes: The application of fast-atom bombardment mass Spectrometry and collisiorutlly induced dissociation with mass-analysed ion kinetic energy (CID/MIKE) Spectrometry of representative inositol mono-, bis- and trisphos-phates is described. Based on their CID/MIKE spectra, inositol polyphosphates containing vicinal phosphate groups could be distinguished from isomers in which adjacent phosphate groups were absent. The potential value of this procedure in studies of the biochemistry of intracellular second messengers is discussed.

    Characterization of glucuronic acid conjugates of a novel angiotensin receptor antagonist (1994)
    New York, NY : Wiley-Blackwell

    Notes: Nanogram quantities of glucuronic acid conjugates of GR117289 in rat and dog bile have been analysed by semi-microbore high-performance liquid chromatography (HPLC)/ionspray mass spectrometry with on-line UV diode array detection. The determination of drug metabolites in bile has often proved problematical due to the large number of endogenous components in this biological matrix, in particular the bile acids. Semi-microbore HPLC is useful for concentrating small quantities of material and, in combination with an on-line diode array detector, for distinguishing between drug related and endogenous components. A novel angiotensin II receptor antagonist, GR117289, had proved difficult to analyse by thermospray mass spectrometry because of its thermal lability. The use of the less thermally dependent technique of ionspray mass spectrometry allowed the characterization of nanogram quantities of glucuronic acid metabolites of GR117289 in bile.

    Structures of zearalenone and zearalanone in solution: A high-field NMR and molecular modelling study (1990)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 28 (1990), S. 835-845 
    Details
    ISSN: 0749-1581
    Keywords: Zearalenone ; Zearalanone ; 1H and 13C NMR ; Molecular modelling ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: The complete 1H and 13C NMR spectra of the mycotoxin zearalenone are described. An analysis of all the vicinal proton-proton coupling constants, together with molecular modelling results, leads to a three-dimensional structure very similar to those observed x-ray crystallographically for related systems. Analogous data on zearalanone reveal that whereas the overall molecular geometry is similar to that of zearalenone, the alkyl terminus of the 12-membered bridging moiety is now oriented almost orthogonally to the aromatic ring plane.

    Topics: Chemistry and Pharmacology
    Notes: The analysis of the 1H and 19F NMR spectra of the corticosteroid fluocinonide and five related steroids is reported. The 500 MHz 1H NMR spectra revealed several previously undetected long-range 1H-19F coupling constants. These couplings were assigned by the application of the heteronuclear equivalent of the COSY pulse sequence. The fluorine substituent effects and long-range heteronuclear couplings were examined in relation to structures derived from molecular mechanics (MMX) calculations.

    An Overview of the NASA Fundamental Aeronautics Program Subsonic Fixed Wing Project and Ultra High Bypass Partnership Research Goals (2009)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: An overview of the NASA Fundamental Aeronautics Program (FAP) mission and goals is presented. One of the subprograms under the FAP, the Subsonic Fixed Wing Project (SFW), is the focus of the presentation. The SFW system environmental metrics are discussed, along with highlights of planned, systematic approach to research to reduce the environmental impact of commercial aircraft in the areas of acoustics, fuel burn and emissions. The presentation then focuses on collaborative research being conducted with U.S. Industry on the Ultra High Bypass (UHB) engine cycle, the propulsion cycle selected by the SFW to meet the system goals. The partnerships with General Electric Aviation to investigate Open Rotor propulsion concepts and with Pratt & Whitney to investigate the Geared Turbofan UHB engine are highlighted, including current and planned future collaborative research activities with NASA and each organization.

    Piloted Simulation of Various Synthetic Vision Systems Terrain Portrayal and Guidance Symbology Concepts for Low Altitude En-Route Scenario (2008)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: In support of the NASA Aviation Safety Program's Synthetic Vision Systems Project, a series of piloted simulations were conducted to explore and quantify the relationship between candidate Terrain Portrayal Concepts and Guidance Symbology Concepts, specific to General Aviation. The experiment scenario was based on a low altitude en route flight in Instrument Metrological Conditions in the central mountains of Alaska. A total of 18 general aviation pilots, with three levels of pilot experience, evaluated a test matrix of four terrain portrayal concepts and six guidance symbology concepts. Quantitative measures included various pilot/aircraft performance data, flight technical errors and flight control inputs. The qualitative measures included pilot comments and pilot responses to the structured questionnaires such as perceived workload, subjective situation awareness, pilot preferences, and the rare event recognition. There were statistically significant effects found from guidance symbology concepts and terrain portrayal concepts but no significant interactions between them. Lower flight technical errors and increased situation awareness were achieved using Synthetic Vision Systems displays, as compared to the baseline Pitch/Roll Flight Director and Blue Sky Brown Ground combination. Overall, those guidance symbology concepts that have both path based guidance cue and tunnel display performed better than the other guidance concepts.

    Terrain Portrayal for Synthetic Vision Systems Head-Down Displays Evaluation Results: Compilation of Pilot Transcripts (2007)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: The Terrain Portrayal for Head-Down Displays (TP-HDD) simulation experiment addressed multiple objectives involving twelve display concepts (two baseline concepts without terrain and ten synthetic vision system (SVS) variations), four evaluation maneuvers (two en route and one approach maneuver, plus a rare-event scenario), and three pilot group classifications. The TP-HDD SVS simulation was conducted in the NASA Langley Research Center's (LaRC's) General Aviation WorkStation (GAWS) facility. The results from this simulation establish the relationship between terrain portrayal fidelity and pilot situation awareness, workload, stress, and performance and are published in the NASA TP entitled Terrain Portrayal for Synthetic Vision Systems Head-Down Displays Evaluation Results. This is a collection of pilot comments during each run of the TP-HDD simulation experiment. These comments are not the full transcripts, but a condensed version where only the salient remarks that applied to the scenario, the maneuver, or the actual research itself were compiled.

    Terrain Portrayal for Synthetic Vision Systems Head-Down Displays Evaluation Results (2007)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: A critical component of SVS displays is the appropriate presentation of terrain to the pilot. At the time of this study, the relationship between the complexity of the terrain presentation and resulting enhancements of pilot SA and pilot performance had been largely undefined. The terrain portrayal for SVS head-down displays (TP-HDD) simulation examined the effects of two primary elements of terrain portrayal on the primary flight display (PFD): variations of digital elevation model (DEM) resolution and terrain texturing. Variations in DEM resolution ranged from sparsely spaced (30 arc-sec) to very closely spaced data (1 arc-sec). Variations in texture involved three primary methods: constant color, elevation-based generic, and photo-realistic, along with a secondary depth cue enhancer in the form of a fishnet grid overlay.
