  6. Building Climate Resilience at NASA Ames Research Center (United States)

    Iraci, L. T.; Mueller, C.; Podolske, J. R.; Milesi, C.


    NASA Ames Research Center, located at the southern end of the San Francisco Bay (SFB) estuary, has identified three primary vulnerabilities to changes in climate. The Ames Climate Adaptation Science Investigator (CASI) workgroup has studied each of these challenges to operations and the potential exposure of infrastructure and employees to an increased frequency of hazards. Sea level rise inundation scenarios for the SFB Area generally refer to projected scenarios in mean sea level rather than changes in extreme tides that could occur during future storm conditions. In the summer of 2014, high resolution 3-D mapping of the low-lying portion of Ames was performed. Those data are integrated with improved sea level inundation scenarios to identify the buildings, basements and drainage systems potentially affected. We will also identify the impacts of sea level and storm surge effects on transportation to and from the Center. This information will help Center management develop future master plans. Climate change will also lead to changes in temperature, storm frequency and intensity. These changes have potential impacts on localized floods and ecosystems, as well as on electricity and water availability. Over the coming decades, these changes will be imposed on top of ongoing land use and land cover changes, especially those deriving from continued urbanization and increase in impervious surface areas. These coupled changes have the potential to create a series of cascading impacts on ecosystems, including changes in primary productivity and disturbance of hydrological properties and increased flood risk. The majority of the electricity used at Ames is supplied by hydroelectric dams, which will be influenced by reductions in precipitation or changes in the timing or phase of precipitation which reduces snow pack. Coupled with increased demand for summertime air conditioning and other cooling needs, NASA Ames is at risk for electricity shortfalls. To assess the

  7. NASA Ames Sustainability Initiatives: Aeronautics, Space Exploration, and Sustainable Futures (United States)

    Grymes, Rosalind A.


    In support of the mission-specific challenges of aeronautics and space exploration, NASA Ames produces a wealth of research and technology advancements with significant relevance to larger issues of planetary sustainability. NASA research on NexGen airspace solutions and its development of autonomous and intelligent technologies will revolutionize both the nation's air transporation systems and have applicability to the low altitude flight economy and to both air and ground transporation, more generally. NASA's understanding of the Earth as a complex of integrated systems contributes to humanity's perception of the sustainability of our home planet. Research at NASA Ames on closed environment life support systems produces directly applicable lessons on energy, water, and resource management in ground-based infrastructure. Moreover, every NASA campus is a 'city'; including an urbanscape and a workplace including scientists, human relations specialists, plumbers, engineers, facility managers, construction trades, transportation managers, software developers, leaders, financial planners, technologists, electricians, students, accountants, and even lawyers. NASA is applying the lessons of our mission-related activities to our urbanscapes and infrastructure, and also anticipates a leadership role in developing future environments for living and working in space.

  8. NASA Ames Arc Jets and Range, Capabilities for Planetary Entry (United States)

    Fretter, Ernest F.


    NASA is pursuing innovative technologies and concepts as part of America's Vision for Space Exploration. The rapidly emerging field of nanotechnology has led to new concepts for multipurpose shields to prevent catastrophic loss of vehicles and crew against the triple threats of aeroheating during atmospheric entry, radiation (Solar and galactic cosmic rays) and Micrometorid/Orbital Debris (MMOD) strikes. One proposed concept is the Thermal Radiation Impact Protection System (TRIPS) using carbon nanotubes, hydrogenated carbon nanotubes, and ceramic coatings as a multi-use TPS. The Thermophysics Facilities Branch of the Space Technology Division at NASA Ames Research Center provides testing services for the development and validation of the present and future concepts being developed by NASA and national and International research firms. The Branch operates two key facilities - the Range Complex and the Arc Jets. The Ranges include both the Ames Vertical Gun Range (AVGR) and the Hypervelocity Free Flight (HFF) gas guns best suited for MMOD investigations. Test coupons can be installed in the AVGR or HFF and subjected to particle impacts from glass or metal particles from micron to _ inch (6.35-mm) diameters and at velocities from 5 to 8 kilometers per second. The facility can record high-speed data on film and provide damage assessment for analysis by the Principle Investigator or Ames personnel. Damaged articles can be installed in the Arc Jet facility for further testing to quantify the effects of damage on the heat shield s performance upon entry into atmospheric environments.

  9. Unique life sciences research facilities at NASA Ames Research Center (United States)

    Mulenburg, G. M.; Vasques, M.; Caldwell, W. F.; Tucker, J.


    The Life Science Division at NASA's Ames Research Center has a suite of specialized facilities that enable scientists to study the effects of gravity on living systems. This paper describes some of these facilities and their use in research. Seven centrifuges, each with its own unique abilities, allow testing of a variety of parameters on test subjects ranging from single cells through hardware to humans. The Vestibular Research Facility allows the study of both centrifugation and linear acceleration on animals and humans. The Biocomputation Center uses computers for 3D reconstruction of physiological systems, and interactive research tools for virtual reality modeling. Psycophysiological, cardiovascular, exercise physiology, and biomechanical studies are conducted in the 12 bed Human Research Facility and samples are analyzed in the certified Central Clinical Laboratory and other laboratories at Ames. Human bedrest, water immersion and lower body negative pressure equipment are also available to study physiological changes associated with weightlessness. These and other weightlessness models are used in specialized laboratories for the study of basic physiological mechanisms, metabolism and cell biology. Visual-motor performance, perception, and adaptation are studied using ground-based models as well as short term weightlessness experiments (parabolic flights). The unique combination of Life Science research facilities, laboratories, and equipment at Ames Research Center are described in detail in relation to their research contributions.

  10. Applied Computational Fluid Dynamics at NASA Ames Research Center (United States)

    Holst, Terry L.; Kwak, Dochan (Technical Monitor)

A few applications being explored at NASA Ames Research Center will be presented and discussed. The examples presented will range in speed from hypersonic to low speed incompressible flow applications. Most of the results will be from numerical solutions of the Navier-Stokes or Euler equations in three space dimensions for general geometry applications. Computational results will be used to highlight the presentation as appropriate. Advances in computational facilities including those associated with NASA's CAS (Computational Aerosciences) Project of the Federal HPCC (High Performance Computing and Communications) Program will be discussed. Finally, opportunities for future research will be presented and discussed. All material will be taken from non-sensitive, previously-published and widely-disseminated work.

  11. A Perspective on NASA Ames Air Traffic Management Research (United States)

    Schroeder, Jeffery A.


    This paper describes past and present air-traffic-management research at NASA Ames Research Center. The descriptions emerge from the perspective of a technical manager who supervised the majority of this research for the last four years. Past research contributions built a foundation for calculating accurate flight trajectories to enable efficient airspace management in time. That foundation led to two predominant research activities that continue to this day - one in automatically separating aircraft and the other in optimizing traffic flows. Today s national airspace uses many of the applications resulting from research at Ames. These applications include the nationwide deployment of the Traffic Management Advisor, new procedures enabling continuous descent arrivals, cooperation with industry to permit more direct flights to downstream way-points, a surface management system in use by two cargo carriers, and software to evaluate how well flights conform to national traffic management initiatives. The paper concludes with suggestions for prioritized research in the upcoming years. These priorities include: enabling more first-look operational evaluations, improving conflict detection and resolution for climbing or descending aircraft, and focusing additional attention on the underpinning safety critical items such as a reliable datalink.

  13. NASA Ames Research Center 60 MW Power Supply Modernization (United States)

    Choy, Yuen Ching; Ilinets, Boris V.; Miller, Ted; Nagel, Kirsten (Technical Monitor)


    The NASA Ames Research Center 60 MW DC Power Supply was built in 1974 to provide controlled DC power for the Thermophysics Facility Arc Jet Laboratory. The Power Supply has gradually losing reliability due to outdated technology and component life limitation. NASA has decided to upgrade the existing rectifier modules with contemporary high-power electronics and control equipment. NASA plans to complete this project in 2001. This project includes a complete replacement of obsolete thyristor stacks in all six rectifier modules and rectifier bridge control system. High power water-cooled thyristors and freewheeling diodes will be used. The rating of each of the six modules will be 4000 A at 5500 V. The control firing angle signal will be sent from the Facility Control System to six modules via fiberoptic cable. The Power Supply control and monitoring system will include a Master PLC in the Facility building and a Slave PLC in each rectifier module. This system will also monitor each thyristor level in each stack and the auxiliary equipment.

  14. Sixth Annual NASA Ames Space Science and Astrobiology Jamboree (United States)

    Hollingsworth, Jeffery; Howell, Steve; Fonda, Mark; Dateo, Chris; Martinez, Christine M.


    Welcome to the Sixth Annual NASA Ames Research Center, Space Science and Astrobiology Jamboree at NASA Ames Research Center (ARC). The Space Science and Astrobiology Division consists of over 60 Civil Servants, with more than 120 Cooperative Agreement Research Scientists, Post-Doctoral Fellows, Science Support Contractors, Visiting Scientists, and many other Research Associates. Within the Division there is engagement in scientific investigations over a breadth of disciplines including Astrobiology, Astrophysics, Exobiology, Exoplanets, Planetary Systems Science, and many more. The Division's personnel support NASA spacecraft missions (current and planned), including SOFIA, K2, MSL, New Horizons, JWST, WFIRST, and others. Our top-notch science research staff is spread amongst three branches in five buildings at ARC. Naturally, it can thus be difficult to remain abreast of what fellow scientific researchers pursue actively, and then what may present and/or offer regarding inter-Branch, intra-Division future collaborative efforts. In organizing this annual jamboree, the goals are to offer a wholesome, one-venue opportunity to sense the active scientific research and spacecraft mission involvement within the Division; and to facilitate communication and collaboration amongst our research scientists. Annually, the Division honors one senior research scientist with a Pollack Lecture, and one early career research scientist with an Outstanding Early Career Space Scientist Lecture. For the Pollack Lecture, the honor is bestowed upon a senior researcher who has made significant contributions within any area of research aligned with space science and/or astrobiology. This year we are pleased to honor Linda Jahnke. With the Early Career Lecture, the honor is bestowed upon an early-career researcher who has substantially demonstrated great promise for significant contributions within space science, astrobiology, and/or, in support of spacecraft missions addressing such

Researchers in the division are pursuing investigations in a variety of fields including exoplanets, planetary science, astrobiology and astrophysics. In addition, division personnel support a wide variety of NASA missions including (but not limited to) Kepler, SOFIA, LADEE, JWST, and New Horizons. With such a wide variety of interesting research going on, distributed among three branches in at least 5 different buildings, it can be difficult to stay abreast of what one's fellow researchers are doing. Our goal in organizing this symposium is to facilitate communication and collaboration among the scientists within the division, and to give center management and other ARC researchers and engineers an opportunity to see what scientific research and science mission work is being done in the division. We are also continuing the tradition within the Space Science and Astrobiology Division to honor one senior and one early career scientist with the Pollack Lecture and the Early Career Lecture, respectively. With the Pollack Lecture, our intent is to select a senior researcher who has made significant contributions to any area of research within the space sciences, and we are pleased to honor Dr. William Borucki this year. With the Early Career Lecture, our intent is to select a young researcher within the division who, by their published scientific papers, shows great promise for the future in any area of space science research, and we are pleased to honor Dr. Melinda Kahre this year

  17. Atmosphere of Freedom: Sixty Years at the NASA Ames Research Center (United States)

    Bugos, Glenn E.; Launius, Roger (Technical Monitor)


    Throughout Ames History, four themes prevail: a commitment to hiring the best people; cutting-edge research tools; project management that gets things done faster, better and cheaper; and outstanding research efforts that serve the scientific professions and the nation. More than any other NASA Center, Ames remains shaped by its origins in the NACA (National Advisory Committee for Aeronautics). Not that its missions remain the same. Sure, Ames still houses the world's greatest collection of wind tunnels and simulation facilities, its aerodynamicists remain among the best in the world, and pilots and engineers still come for advice on how to build better aircraft. But that is increasingly part of Ames' past. Ames people have embraced two other missions for its future. First, intelligent systems and information science will help NASA use new tools in supercomputing, networking, telepresence and robotics. Second, astrobiology will explore lore the prospects for life on Earth and beyond. Both new missions leverage Ames long-standing expertise in computation and in the life sciences, as well as its relations with the computing and biotechnology firms working in the Silicon Valley community that has sprung up around the Center. Rather than the NACA missions, it is the NACA culture that still permeates Ames. The Ames way of research management privileges the scientists and engineers working in the laboratories. They work in an atmosphere of freedom, laced with the expectation of integrity and responsibility. Ames researchers are free to define their research goals and define how they contribute to the national good. They are expected to keep their fingers on the pulse of their disciplines, to be ambitious yet frugal in organizing their efforts, and to always test their theories in the laboratory or in the field. Ames' leadership ranks, traditionally, are cultivated within this scientific community. Rather than manage and supervise these researchers, Ames leadership merely

  19. NASA's Great Observatories Celebrate International Year of Astronomy (United States)


    A never-before-seen view of the turbulent heart of our Milky Way galaxy is being unveiled by NASA on Nov. 10. This event will commemorate the 400 years since Galileo first turned his telescope to the heavens in 1609. In celebration of this International Year of Astronomy, NASA is releasing images of the galactic center region as seen by its Great Observatories to more than 150 planetariums, museums, nature centers, libraries, and schools across the country. The sites will unveil a giant, 6-foot-by-3-foot print of the bustling hub of our galaxy that combines a near-infrared view from the Hubble Space Telescope, an infrared view from the Spitzer Space Telescope, and an X-ray view from the Chandra X-ray Observatory into one multiwavelength picture. Experts from all three observatories carefully assembled the final image from large mosaic photo surveys taken by each telescope. This composite image provides one of the most detailed views ever of our galaxy's mysterious core. Participating institutions also will display a matched trio of Hubble, Spitzer, and Chandra images of the Milky Way's center on a second large panel measuring 3 feet by 4 feet. Each image shows the telescope's different wavelength view of the galactic center region, illustrating not only the unique science each observatory conducts, but also how far astronomy has come since Galileo. The composite image features the spectacle of stellar evolution: from vibrant regions of star birth, to young hot stars, to old cool stars, to seething remnants of stellar death called black holes. This activity occurs against a fiery backdrop in the crowded, hostile environment of the galaxy's core, the center of which is dominated by a supermassive black hole nearly four million times more massive than our Sun. Permeating the region is a diffuse blue haze of X-ray light from gas that has been heated to millions of degrees by outflows from the supermassive black hole as well as by winds from massive stars and by stellar

  2. Cultivating a Grassroots Aerospace Innovation Culture at NASA Ames Research Center (United States)

    D'Souza, Sarah; Sanchez, Hugo; Lewis, Ryan


    This paper details the adaptation of specific 'knowledge production' methods to implement a first of its kind, grassroots event that provokes a cultural change in how the NASA Ames civil servant community engages in the creation and selection of innovative ideas. Historically, selection of innovative proposals at NASA Ames Research Center is done at the highest levels of management, isolating the views and perspectives of the larger civil servant community. Additionally, NASA innovation programs are typically open to technical organizations and do not engage non-technical organizations to bring forward innovative processes/business practices. Finally, collaboration on innovative ideas and associated solutions tend to be isolated to organizational silos. In this environment, not all Ames employees feel empowered to innovate and opportunities for employee collaboration are limited. In order to address these issues, the 'innovation contest' method was adapted to create the NASA Ames Innovation Fair, a unique, grassroots innovation opportunity for the civil servant community. The Innovation Fair consisted of a physical event with a virtual component. The physical event provided innovators the opportunity to collaborate and pitch their innovations to the NASA Ames community. The civil servant community then voted for the projects that they viewed as innovative and would contribute to NASA's core mission, making this event a truly grassroots effort. The Innovation Fair website provided a location for additional knowledge sharing, discussion, and voting. On March 3rd, 2016, the 'First Annual NASA Ames Innovation Fair' was held with 49 innovators and more than 300 participants collaborating and/or voting for the best innovations. Based on the voting results, seven projects were awarded seed funding for projects ranging from innovative cost models to innovations in aerospace technology. Surveys of both innovators and Fair participants show the Innovation Fair was successful

  3. NASA's Great Observatories Celebrate the International Year of Astronomy (United States)


    [figure removed for brevity, see original site] Click on the image for larger version In 1609, Galileo improved the newly invented telescope, turned it toward the heavens, and revolutionized our view of the universe. In celebration of the 400th anniversary of this milestone, 2009 has been designated as the International Year of Astronomy. Today, NASA's Great Observatories are continuing Galileo's legacy with stunning images and breakthrough science from the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory. While Galileo observed the sky using visible light seen by the human eye, technology now allows us to observe in many wavelengths, including Spitzer's infrared view and Chandra's view in X-rays. Each wavelength region shows different aspects of celestial objects and often reveals new objects that could not otherwise be studied. This image of the spiral galaxy Messier 101 is a composite of views from Spitzer, Hubble, and Chandra. The red color shows Spitzer's view in infrared light. It highlights the heat emitted by dust lanes in the galaxy where stars can form. The yellow color is Hubble's view in visible light. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes. The blue color shows Chandra's view in X-ray light. Sources of X-rays include million-degree gas, exploded stars, and material colliding around black holes. Such composite images allow astronomers to see how features seen in one wavelength match up with those seen in another wavelength. It's like seeing with a camera, night vision goggles, and X-ray vision all at once. In the four centuries since Galileo, astronomy has changed dramatically. Yet our curiosity and quest for knowledge remain the same. So, too, does our wonder at the splendor of the universe. The International Year of Astronomy Great Observatories Image Unveiling is supported by the NASA Science Mission Directorate Astrophysics Division. The project is a

  5. The NASA Ames Life Sciences Data Archive: Biobanking for the Final Frontier (United States)

    Rask, Jon; Chakravarty, Kaushik; French, Alison J.; Choi, Sungshin; Stewart, Helen J.


    The NASA Ames Institutional Scientific Collection involves the Ames Life Sciences Data Archive (ALSDA) and a biospecimen repository, which are responsible for archiving information and non-human biospecimens collected from spaceflight and matching ground control experiments. The ALSDA also manages a biospecimen sharing program, performs curation and long-term storage operations, and facilitates distribution of biospecimens for research purposes via a public website ( As part of our best practices, a tissue viability testing plan has been developed for the repository, which will assess the quality of samples subjected to long-term storage. We expect that the test results will confirm usability of the samples, enable broader science community interest, and verify operational efficiency of the archives. This work will also support NASA open science initiatives and guides development of NASA directives and policy for curation of biological collections.

  11. Consolidated Laser-Induced Fluorescence Diagnostic Systems for the NASA Ames Arc Jet Facilities (United States)

    Grinstead, Jay; Wilder, Michael C.; Porter, Barry; Brown, Jeff; Yeung, Dickson; Battazzo, Steve; Brubaker, Tim


    The spectroscopic diagnostic technique of two photon absorption laser-induced fluorescence (TALIF) of atomic species for non-intrusive arc jet flow property measurement was first implemented at NASA Ames in the mid-1990s. Use of TALIF expanded at NASA Ames and to NASA Johnsons arc jet facility in the late 2000s. In 2013-2014, NASA combined the agency's large-scale arc jet test capabilities at NASA Ames. Concurrent with that effort, the agency also sponsored a project to establish two comprehensive LIF diagnostic systems for the Aerodynamic Heating Facility (AHF) and Interaction Heating Facility (IHF) arc jets. The scope of the project enabled further engineering development of the existing IHF LIF system as well as the complete reconstruction of the original AHF LIF system. The updated LIF systems are identical in design and capability. They represent the culmination of over 20 years of development experience in transitioning a specialized laboratory research tool into a measurement system for large-scale, high-demand test facilities. This paper documents the overall system design from measurement requirements to implementation. Representative data from the redeveloped AHF and IHF LIF systems are also presented.

  12. NASA Ames DEVELOP Interns: Helping the Western United States Manage Natural Resources One Project at a Time (United States)

    Justice, Erin; Newcomer, Michelle


    The western half of the United States is made up of a number of diverse ecosystems ranging from arid desert to coastal wetlands and rugged forests. Every summer for the past 7 years students ranging from high school to graduate level gather at NASA Ames Research Center (ARC) as part of the DEVELOP Internship Program. Under the guidance of Jay Skiles [Ames Research Center (ARC) - Ames DEVELOP Manager] and Cindy Schmidt [ARC/San Jose State University Ames DEVELOP Coordinator] they work as a team on projects exploring topics including: invasive species, carbon flux, wetland restoration, air quality monitoring, storm visualizations, and forest fires. The study areas for these projects have been in Washington, Utah, Oregon, Nevada, Hawaii, Alaska and California. Interns combine data from NASA and partner satellites with models and in situ measurements to complete prototype projects demonstrating how NASA data and resources can help communities tackle their Earth Science related problems.

  13. The NASA Ames Research Center Institutional Scientific Collection: History, Best Practices and Scientific Opportunities (United States)

    Rask, Jon C.; Chakravarty, Kaushik; French, Alison; Choi, Sungshin; Stewart, Helen


    The NASA Ames Life Sciences Institutional Scientific Collection (ISC), which is composed of the Ames Life Sciences Data Archive (ALSDA) and the Biospecimen Storage Facility (BSF), is managed by the Space Biosciences Division and has been operational since 1993. The ALSDA is responsible for archiving information and animal biospecimens collected from life science spaceflight experiments and matching ground control experiments. Both fixed and frozen spaceflight and ground tissues are stored in the BSF within the ISC. The ALSDA also manages a Biospecimen Sharing Program, performs curation and long-term storage operations, and makes biospecimens available to the scientific community for research purposes via the Life Science Data Archive public website ( As part of our best practices, a viability testing plan has been developed for the ISC, which will assess the quality of archived samples. We expect that results from the viability testing will catalyze sample use, enable broader science community interest, and improve operational efficiency of the ISC. The current viability test plan focuses on generating disposition recommendations and is based on using ribonucleic acid (RNA) integrity number (RIN) scores as a criteria for measurement of biospecimen viablity for downstream functional analysis. The plan includes (1) sorting and identification of candidate samples, (2) conducting a statiscally-based power analysis to generate representaive cohorts from the population of stored biospecimens, (3) completion of RIN analysis on select samples, and (4) development of disposition recommendations based on the RIN scores. Results of this work will also support NASA open science initiatives and guides development of the NASA Scientific Collections Directive (a policy on best practices for curation of biological collections). Our RIN-based methodology for characterizing the quality of tissues stored in the ISC since the 1980s also creates unique

  14. Development and operation of a real-time simulation at the NASA Ames Vertical Motion Simulator (United States)

    Sweeney, Christopher; Sheppard, Shirin; Chetelat, Monique


    The Vertical Motion Simulator (VMS) facility at the NASA Ames Research Center combines the largest vertical motion capability in the world with a flexible real-time operating system allowing research to be conducted quickly and effectively. Due to the diverse nature of the aircraft simulated and the large number of simulations conducted annually, the challenge for the simulation engineer is to develop an accurate real-time simulation in a timely, efficient manner. The SimLab facility and the software tools necessary for an operating simulation will be discussed. Subsequent sections will describe the development process through operation of the simulation; this includes acceptance of the model, validation, integration and production phases.

    The astronomical emission features, formerly known as the unidentified infrared bands, are now commonly ascribed to polycyclic aromatic hydrocarbons (PAHs). The laboratory experiments and computational modeling done at the NASA Ames Research Center to create a collection of PAH IR spectra relevant to test and refine the PAH hypothesis have been assembled into a spectroscopic database. This database now contains over 800 PAH spectra spanning 2-2000 μm (5000-5 cm -1 ). These data are now available on the World Wide Web at This paper presents an overview of the computational spectra in the database and the tools developed to analyze and interpret astronomical spectra using the database. A description of the online and offline user tools available on the Web site is also presented.

  16. Development of Implicit Methods in CFD NASA Ames Research Center 1970's - 1980's (United States)

    Pulliam, Thomas H.


    The focus here is on the early development (mid 1970's-1980's) at NASA Ames Research Center of implicit methods in Computational Fluid Dynamics (CFD). A class of implicit finite difference schemes of the Beam and Warming approximate factorization type will be addressed. The emphasis will be on the Euler equations. A review of material pertinent to the solution of the Euler equations within the framework of implicit methods will be presented. The eigensystem of the equations will be used extensively in developing a framework for various methods applied to the Euler equations. The development and analysis of various aspects of this class of schemes will be given along with the motivations behind many of the choices. Various acceleration and efficiency modifications such as matrix reduction, diagonalization and flux split schemes will be presented.

  17. Reduction of Background Noise in the NASA Ames 40- by 80-Foot Wind Tunnel (United States)

    Jaeger, Stephen M.; Allen, Christopher S.; Soderman, Paul T.; Olson, Larry E. (Technical Monitor)


    Background noise in both open-jet and closed wind tunnels adversely affects the signal-to-noise ratio of acoustic measurements. To measure the noise of increasingly quieter aircraft models, the background noise will have to be reduced by physical means or through signal processing. In a closed wind tunnel, such as the NASA Ames 40- by 80- Foot Wind Tunnel, the principle background noise sources can be classified as: (1) fan drive noise; (2) microphone self-noise; (3) aerodynamically induced noise from test-dependent hardware such as model struts and junctions; and (4) noise from the test section walls and vane set. This paper describes the steps taken to minimize the influence of each of these background noise sources in the 40 x 80.

  18. New Diagnostic, Launch and Model Control Techniques in the NASA Ames HFFAF Ballistic Range (United States)

    Bogdanoff, David W.


    This report presents new diagnostic, launch and model control techniques used in the NASA Ames HFFAF ballistic range. High speed movies were used to view the sabot separation process and the passage of the model through the model splap paper. Cavities in the rear of the sabot, to catch the muzzle blast of the gun, were used to control sabot finger separation angles and distances. Inserts were installed in the powder chamber to greatly reduce the ullage volume (empty space) in the chamber. This resulted in much more complete and repeatable combustion of the powder and hence, in much more repeatable muzzle velocities. Sheets of paper or cardstock, impacting one half of the model, were used to control the amplitudes of the model pitch oscillations.

    International Nuclear Information System (INIS)

    Elliott, R.D.


    A series of ablation tests of lithium hydride has been made by NASA-Ames in one of their high-enthalpy arc-heated wind tunnels. Two-inch diameter cylindrical samples of the hydride, supplied by A. I., were subjected to heating on their ends for time periods up to 10 seconds. After each test, the amount of material removed from each sample was measured. The rates of loss of material were correlated with the heat input rates in terms of a heat of ablation, which ranged from 2100 to 3500 Btu/lb. The higher values were obtained when the hydride contained a matrix such as steel honeycomb of steel wool. (U.S.)

  20. Updates on Modeling the Water Cycle with the NASA Ames Mars Global Climate Model (United States)

    Kahre, M. A.; Haberle, R. M.; Hollingsworth, J. L.; Montmessin, F.; Brecht, A. S.; Urata, R.; Klassen, D. R.; Wolff, M. J.


    Global Circulation Models (GCMs) have made steady progress in simulating the current Mars water cycle. It is now widely recognized that clouds are a critical component that can significantly affect the nature of the simulated water cycle. Two processes in particular are key to implementing clouds in a GCM: the microphysical processes of formation and dissipation, and their radiative effects on heating/ cooling rates. Together, these processes alter the thermal structure, change the dynamics, and regulate inter-hemispheric transport. We have made considerable progress representing these processes in the NASA Ames GCM, particularly in the presence of radiatively active water ice clouds. We present the current state of our group's water cycle modeling efforts, show results from selected simulations, highlight some of the issues, and discuss avenues for further investigation.­

  1. Educational Projects in Unmanned Aerial Systems at the NASA Ames Research Center (United States)

    Dahlgren, Robert P.


    Unmanned aerial systems (UAS), autonomy and robotics technology have been fertile ground for developing a wide variety of interdisciplinary student learning opportunities. In this talk, several projects will be described that leverage small fixed-wing UAS that have been modified to carry science payloads. These aircraft provide a unique hands-on experience for a wide range of students from college juniors to graduate students pursuing degrees in electrical engineering, aeronautical engineering, mechanical engineering, applied mathematics, physics, structural engineering and other majors. By combining rapid prototyping, design reuse and open-source philosophies, a sustainable educational program has been organized structured as full-time internships during the summer, part-time internships during the school year, short details for military cadets, and paid positions. As part of this program, every summer one or more UAS is developed from concept through design, build and test phases using the tools and facilities at the NASA Ames Research Center, ultimately obtaining statements of airworthiness and flight release from the Agency before test flights are performed. In 2016 and 2017 student projects focused on the theme of 3D printed modular airframes that may be optimized for a given mission and payload. Now in its fifth year this program has served over 35 students, and has provided a rich learning experience as they learn to rapidly develop new aircraft concepts in a highly regulated environment, on systems that will support principal investigators at university, NASA, and other US federal agencies.

  2. Training for life science experiments in space at the NASA Ames Research Center (United States)

    Rodrigues, Annette T.; Maese, A. Christopher


    As this country prepares for exploration to other planets, the need to understand the affects of long duration exposure to microgravity is evident. The National Aeronautics and Space Administration (NASA) Ames Research Center's Space Life Sciences Payloads Office is responsible for a number of non-human life sciences payloads on NASA's Space Shuttle's Spacelab. Included in this responsibility is the training of those individuals who will be conducting the experiments during flight, the astronauts. Preparing a crew to conduct such experiments requires training protocols that build on simple tasks. Once a defined degree of performance proficiency is met for each task, these tasks are combined to increase the complexity of the activities. As tasks are combined into in-flight operations, they are subjected to time constraints and the crew enhances their skills through repetition. The science objectives must be completely understood by the crew and are critical to the overall training program. Completion of the in-flight activities is proof of success. Because the crew is exposed to the background of early research and plans for post-flight analyses, they have a vested interest in the flight activities. The salient features of this training approach is that it allows for flexibility in implementation, consideration of individual differences, and a greater ability to retain experiment information. This training approach offers another effective alternative training tool to existing methodologies.

(LBNL), Berkeley, CA (United States); Parrish, Kristen [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Bazjanac, Vladimir [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)


    Typical processes of whole Building Energy simulation Model (BEM) generation are subjective, labor intensive, time intensive and error prone. Essentially, these typical processes reproduce already existing data, i.e. building models already created by the architect. Accordingly, Lawrence Berkeley National Laboratory (LBNL) developed a semi-automated process that enables reproducible conversions of Building Information Model (BIM) representations of building geometry into a format required by building energy modeling (BEM) tools. This is a generic process that may be applied to all building energy modeling tools but to date has only been used for EnergyPlus. This report describes and demonstrates each stage in the semi-automated process for building geometry using the recently constructed NASA Ames Sustainability Base throughout. This example uses ArchiCAD (Graphisoft, 2012) as the originating CAD tool and EnergyPlus as the concluding whole building energy simulation tool. It is important to note that the process is also applicable for professionals that use other CAD tools such as Revit (“Revit Architecture,” 2012) and DProfiler (Beck Technology, 2012) and can be extended to provide geometry definitions for BEM tools other than EnergyPlus. Geometry Simplification Tool (GST) was used during the NASA Ames project and was the enabling software that facilitated semi-automated data transformations. GST has now been superseded by Space Boundary Tool (SBT-1) and will be referred to as SBT-1 throughout this report. The benefits of this semi-automated process are fourfold: 1) reduce the amount of time and cost required to develop a whole building energy simulation model, 2) enable rapid generation of design alternatives, 3) improve the accuracy of BEMs and 4) result in significantly better performing buildings with significantly lower energy consumption than those created using the traditional design process, especially if the simulation model was used as a predictive

  4. The NASA Ames Hypersonic Combustor-Model Inlet CFD Simulations and Experimental Comparisons (United States)

    Venkatapathy, E.; Tokarcik-Polsky, S.; Deiwert, G. S.; Edwards, Thomas A. (Technical Monitor)


    Computations have been performed on a three-dimensional inlet associated with the NASA Ames combustor model for the hypersonic propulsion experiment in the 16-inch shock tunnel. The 3-dimensional inlet was designed to have the combustor inlet flow nearly two-dimensional and of sufficient mass flow necessary for combustion. The 16-inch shock tunnel experiment is a short duration test with test time of the order of milliseconds. The flow through the inlet is in chemical non-equilibrium. Two test entries have been completed and limited experimental results for the inlet region of the combustor-model are available. A number of CFD simulations, with various levels of simplifications such as 2-D simulations, 3-D simulations with and without chemical reactions, simulations with and without turbulent conditions, etc., have been performed. These simulations have helped determine the model inlet flow characteristics and the important factors that affect the combustor inlet flow and the sensitivity of the flow field to these simplifications. In the proposed paper, CFD modeling of the hypersonic inlet, results from the simulations and comparison with available experimental results will be presented.

  5. Sources and levels of background noise in the NASA Ames 40- by 80-foot wind tunnel (United States)

    Soderman, Paul T.


    Background noise levels are measured in the NASA Ames Research Center 40- by 80-Foot Wind Tunnel following installation of a sound-absorbent lining on the test-section walls. Results show that the fan-drive noise dominated the empty test-section background noise at airspeeds below 120 knots. Above 120 knots, the test-section broadband background noise was dominated by wind-induced dipole noise (except at lower harmonics of fan blade-passage tones) most likely generated at the microphone or microphone support strut. Third-octave band and narrow-band spectra are presented for several fan operating conditions and test-section airspeeds. The background noise levels can be reduced by making improvements to the microphone wind screen or support strut. Empirical equations are presented relating variations of fan noise with fan speed or blade-pitch angle. An empirical expression for typical fan noise spectra is also presented. Fan motor electric power consumption is related to the noise generation. Preliminary measurements of sound absorption by the test-section lining indicate that the 152 mm thick lining will adequately absorb test-section model noise at frequencies above 300 Hz.

  6. Emission Spectroscopy and Radiometric Measurements in the NASA Ames IHF Arc Jet Facility (United States)

    Winter, Michael W.; Raiche, George A.; Prabhu, Dinesh K.


    Plasma diagnostic measurement campaigns in the NASA Ames Interaction Heating Facility (IHF) have been conducted over the last several years with a view towards characterizing the flow in the arc jet facility by providing data necessary for modeling and simulation. Optical emission spectroscopy has been used in the plenum and in the free jet of the nozzle. Radiation incident over a probe surface has also been measured using radiometry. Plenum measurements have shown distinct radial profiles of temperature over a range of operating conditions. For cases where large amounts of cold air are added radially to the main arc-heated stream, the temperature profiles are higher by as much as 1500 K than the profiles assumed in flow simulations. Optical measurements perpendicular to the flow direction in the free jet showed significant contributions to the molecule emission through inverse pre-dissociation, thus allowing determination of atom number densities from molecular emission. This has been preliminarily demonstrated with the N2 1st Positive System. Despite the use of older rate coefficients, the resulting atom densities are reasonable and surprisingly close to flow predictions.

  7. Viking GCMS Data Restoral and Perceiving Temperature on Other Worlds: Astrobiology Projects at NASA Ames (United States)

    Guzman, Melissa


    The primary task for the summer was to procure the GCMS data from the National Space Science Data Coordinated Archive (NSSDCA) and to assess the current state of the data set for possible reanalysis opportunities. After procurement of the Viking GCMS data set and analysis of its current state, the internship focus shifted to preparing a plan for restoral and archiving of the GCMS data set. A proposal was prepared and submitted to NASA Headquarters to restore and make available the 8000 mass chromatographs that are the basic data generated by the Viking GCMS instrument. The relevance of this restoral and the methodology we propose for restoral is presented. The secondary task for the summer is to develop a thermal model for the perceived temperature of a human standing on Mars, Titan, or Europa. Traditionally, an equation called "Fanger's comfort equation" is used to measure the perceived temperature by a human in a given reference environment. However, there are limitations to this model when applied to other planets. Therefore, the approach for this project has been to derive energy balance equations from first principles and then develop a methodology for correlating "comfort" to energy balance. Using the -20 C walk-in freezer in the Space Sciences building at NASA Ames, energy loss of a human subject is measured. Energy loss for a human being on Mars, Titan and Europa are calculated from first principles. These calculations are compared to the freezer measurements, e.g. for 1 minute on Titan, a human loses as much energy as x minutes in a -20 C freezer. This gives a numerical comparison between the environments. These energy calculations are used to consider the physiological comfort of a human based on the calculated energy losses.

  8. Simulating the Current Water Cycle with the NASA Ames Mars Global Climate Model (United States)

    Kahre, M. A.; Haberle, R. M.; Hollingsworth, J. L.; Brecht, A. S.; Urata, R. A.; Montmessin, F.


    The water cycle is a critical component of the current Mars climate system, and it is now widely recognized that water ice clouds significantly affect the nature of the simulated water cycle. Two processes are key to implementing clouds in a Mars global climate model (GCM): the microphysical processes of formation and dissipation, and their radiative effects on atmospheric heating/cooling rates. Together, these processes alter the thermal structure, change the atmospheric dynamics, and regulate inter-hemispheric transport. We have made considerable progress using the NASA Ames Mars GCM to simulate the current-day water cycle with radiatively active clouds. Cloud fields from our baseline simulation are in generally good agreement with observations. The predicted seasonal extent and peak IR optical depths are consistent MGS/TES observations. Additionally, the thermal response to the clouds in the aphelion cloud belt (ACB) is generally consistent with observations and other climate model predictions. Notably, there is a distinct gap in the predicted clouds over the North Residual Cap (NRC) during local summer, but the clouds reappear in this simulation over the NRC earlier than the observations indicate. Polar clouds are predicted near the seasonal CO2 ice caps, but the column thicknesses of these clouds are generally too thick compared to observations. Our baseline simulation is dry compared to MGS/TES-observed water vapor abundances, particularly in the tropics and subtropics. These areas of disagreement appear to be a consistent with other current water cycle GCMs. Future avenues of investigation will target improving our understanding of what controls the vertical extent of clouds and the apparent seasonal evolution of cloud particle sizes within the ACB.

  9. Recent Progress in Planetary Laboratory Astrophysics achieved with NASA Ames' COSmIC Facility (United States)

    Salama, Farid; Sciamma-O'Brien, Ella; Bejaoui, Salma


    We describe the characteristics and the capabilities of the laboratory facility, COSmIC, that was developed at NASA Ames to generate, process and analyze interstellar, circumstellar and planetary analogs in the laboratory [1]. COSmIC stands for "Cosmic Simulation Chamber" and is dedicated to the study of neutral and ionized molecules and nanoparticles under the low temperature and high vacuum conditions that are required to simulate various space environments such as planetary atmospheres. COSmIC integrates a variety of state-of-the-art instruments that allow forming, processing and monitoring simulated space conditions for planetary, circumstellar and interstellar materials in the laboratory. The COSmIC experimental setup is composed of a Pulsed Discharge Nozzle (PDN) expansion, that generates a plasma in the stream of a free supersonic jet expansion, coupled to two high-sensitivity, complementary in situ diagnostics: a Cavity Ring Down Spectroscopy (CRDS) and laser induced fluorescence (LIF) systems for photonic detection [2, 3], and a Reflectron Time-Of-Flight Mass Spectrometer (ReTOF-MS) for mass detection [4].Recent results obtained using COSmIC will be highlighted. In particular, the progress that has been achieved in an on-going study investigating the formation and the characterization of laboratory analogs of Titan's aerosols generated from gas-phase molecular precursors [5] will be presented. Plans for future laboratory experiments on planetary molecules and aerosols in the growing field of planetary laboratory astrophysics will also be addressed, as well as the implications of studies underway for astronomical observations.References: [1] Salama F., in Organic Matter in Space, IAU S251, Kwok & Sandford eds, CUP, S251, 4, 357 (2008).[2] Biennier L., Salama, F., Allamandola L., & Scherer J., J.

  10. M2-F1 mounted in NASA Ames Research Center 40x80 foot wind tunnel (United States)


    After the first attempted ground-tow tests of the M2-F1 in March 1963, the vehicle was taken to the Ames Research Center, Mountain View, CA, for wind-tunnel testing. During these tests, Milt Thompson and others were in the M2-F1 to position the control surfaces for each test. The wingless, lifting body aircraft design was initially conceived as a means of landing an aircraft horizontally after atmospheric reentry. The absence of wings would make the extreme heat of re-entry less damaging to the vehicle. In 1962, Dryden management approved a program to build a lightweight, unpowered lifting body as a prototype to flight test the wingless concept. It would look like a 'flying bathtub,' and was designated the M2-F1, the 'M' referring to 'manned' and 'F' referring to 'flight' version. It featured a plywood shell placed over a tubular steel frame crafted at Dryden. Construction was completed in 1963. The first flight tests of the M2-F1 were over Rogers Dry Lake at the end of a tow rope attached to a hopped-up Pontiac convertible driven at speeds up to about 120 mph. This vehicle needed to be able to tow the M2-F1 on the Rogers Dry Lakebed adjacent to NASA's Flight Research Center (FRC) at a minimum speed of 100 miles per hour. To do that, it had to handle the 400-pound pull of the M2-F1. Walter 'Whitey' Whiteside, who was a retired Air Force maintenance officer working in the FRC's Flight Operations Division, was a dirt-bike rider and hot-rodder. Together with Boyden 'Bud' Bearce in the Procurement and Supply Branch of the FRC, Whitey acquired a Pontiac Catalina convertible with the largest engine available. He took the car to Bill Straup's renowned hot-rod shop near Long Beach for modification. With a special gearbox and racing slicks, the Pontiac could tow the 1,000-pound M2-F1 110 miles per hour in 30 seconds. It proved adequate for the roughly 400 car tows that got the M2-F1 airborne to prove it could fly safely and to train pilots before they were towed behind a C

  11. Model Deformation and Optical Angle of Attack Measurement System in the NASA Ames Unitary Plan Wind Tunnel (United States)

    Kushner, Laura K.; Drain, Bethany A.; Schairer, Edward T.; Heineck, James T.; Bell, James H.


    Both AoA and MDM measurements can be made using an optical system that relies on photogrammetry. Optical measurements are being requested by customers in wind tunnels with increasing frequency due to their non-intrusive nature and recent hardware and software advances that allow measurements to become near real time. The NASA Ames Research Center Unitary Plan Wind Tunnel is currently developing a system based on photogrammetry to measure model deformation and model angle of attack. This paper describes the new system, its development, its use on recent tests and plans to further develop the system.

  12. Experiences with a high-blockage model tested in the NASA Ames 12-foot pressure wind tunnel (United States)

    Coder, D. W.


    Representation of the flow around full-scale ships was sought in the subsonic wind tunnels in order to a Hain Reynolds numbers as high as possible. As part of the quest to attain the largest possible Reynolds number, large models with high blockage are used which result in significant wall interference effects. Some experiences with such a high blockage model tested in the NASA Ames 12-foot pressure wind tunnel are summarized. The main results of the experiment relating to wind tunnel wall interference effects are also presented.

  13. Construction of a 2- by 2-foot transonic adaptive-wall test section at the NASA Ames Research Center (United States)

    Morgan, Daniel G.; Lee, George


    The development of a new production-size, two-dimensional, adaptive-wall test section with ventilated walls at the NASA Ames Research Center is described. The new facility incorporates rapid closed-loop operation, computer/sensor integration, and on-line interference assessment and wall corrections. Air flow through the test section is controlled by a series of plenum compartments and three-way slide vales. A fast-scan laser velocimeter was built to measure velocity boundary conditions for the interference assessment scheme. A 15.2-cm- (6.0-in.-) chord NACA 0012 airfoil model will be used in the first experiments during calibration of the facility.

  14. Performance of the OVERFLOW-MLP and LAURA-MLP CFD Codes on the NASA Ames 512 CPU Origin System (United States)

    Taft, James R.


    The shared memory Multi-Level Parallelism (MLP) technique, developed last year at NASA Ames has been very successful in dramatically improving the performance of important NASA CFD codes. This new and very simple parallel programming technique was first inserted into the OVERFLOW production CFD code in FY 1998. The OVERFLOW-MLP code's parallel performance scaled linearly to 256 CPUs on the NASA Ames 256 CPU Origin 2000 system (steger). Overall performance exceeded 20.1 GFLOP/s, or about 4.5x the performance of a dedicated 16 CPU C90 system. All of this was achieved without any major modification to the original vector based code. The OVERFLOW-MLP code is now in production on the inhouse Origin systems as well as being used offsite at commercial aerospace companies. Partially as a result of this work, NASA Ames has purchased a new 512 CPU Origin 2000 system to further test the limits of parallel performance for NASA codes of interest. This paper presents the performance obtained from the latest optimization efforts on this machine for the LAURA-MLP and OVERFLOW-MLP codes. The Langley Aerothermodynamics Upwind Relaxation Algorithm (LAURA) code is a key simulation tool in the development of the next generation shuttle, interplanetary reentry vehicles, and nearly all "X" plane development. This code sustains about 4-5 GFLOP/s on a dedicated 16 CPU C90. At this rate, expected workloads would require over 100 C90 CPU years of computing over the next few calendar years. It is not feasible to expect that this would be affordable or available to the user community. Dramatic performance gains on cheaper systems are needed. This code is expected to be perhaps the largest consumer of NASA Ames compute cycles per run in the coming year.The OVERFLOW CFD code is extensively used in the government and commercial aerospace communities to evaluate new aircraft designs. It is one of the largest consumers of NASA supercomputing cycles and large simulations of highly resolved full

  16. Adjoint Method and Predictive Control for 1-D Flow in NASA Ames 11-Foot Transonic Wind Tunnel (United States)

    Nguyen, Nhan; Ardema, Mark


    This paper describes a modeling method and a new optimal control approach to investigate a Mach number control problem for the NASA Ames 11-Foot Transonic Wind Tunnel. The flow in the wind tunnel is modeled by the 1-D unsteady Euler equations whose boundary conditions prescribe a controlling action by a compressor. The boundary control inputs to the compressor are in turn controlled by a drive motor system and an inlet guide vane system whose dynamics are modeled by ordinary differential equations. The resulting Euler equations are thus coupled to the ordinary differential equations via the boundary conditions. Optimality conditions are established by an adjoint method and are used to develop a model predictive linear-quadratic optimal control for regulating the Mach number due to a test model disturbance during a continuous pitch

    NASA Ames Research Center and Rockwell International are partners in a Cooperative Agreement (CA) for the development of Thermal Protection Systems (TPS) for the Reusable Launch Vehicle (RLV) Technology Program. This Cooperative Agreement is a 30 month effort focused on transferring NASA innovations to Rockwell and working as partners to advance the state-of-the-art in several TPS areas. The use of a Cooperative Agreement is a new way of doing business for NASA and Industry which eliminates the traditional customer/contractor relationship and replaces it with a NASA/Industry partnership.

  18. Report of the Interagency Optical Network Testbeds Workshop 2, NASA Ames Research Center, September 12-14, 2005 (United States)


    The Optical Network Testbeds Workshop 2 (ONT2), held on September 12-14, 2005, was cosponsored by the Department of Energy Office of Science (DOE/SC) and the National Aeronautics and Space Administration (NASA), in cooperation with the Joint Engineering Team (JET) of the Federal Networking and Information Technology Research and Development (NITRD) Program's Large Scale Networking (LSN) Coordinating Group. The ONT2 workshop was a follow-on to an August 2004 Workshop on Optical Network Testbeds (ONT1). ONT1 recommended actions by the Federal agencies to assure timely development and implementation of optical networking technologies and infrastructure. Hosted by the NASA Ames Research Center in Mountain View, California, the ONT2 workshop brought together representatives of the U.S. advanced research and education (R&E) networks, regional optical networks (RONs), service providers, international networking organizations, and senior engineering and R&D managers from Federal agencies and national research laboratories. Its purpose was to develop a common vision of the optical network technologies, services, infrastructure, and organizations needed to enable widespread use of optical networks; recommend activities for transitioning the optical networking research community and its current infrastructure to leading-edge optical networks over the next three to five years; and present information enabling commercial network infrastructure providers to plan for and use leading-edge optical network services in that time frame.

  19. Retrospective of photography at NASA Ames Research Center from 1940 to 1996 (Extended Abstract) (United States)

    Ponseggi, Bernard G.


    This paper deals with what is known as photo/optical instrumentation technology and/or technical photography. In 1940 this was called photography, in the late 40's the Civil Service Commission introduced a new classification called photography/technical to differentiate between still photographers and those engaging in recording engineering data. In October of 1958 a historic event took place, Congress transferred all of the duties of NACA to a newly formed agency called NASA, and with it came a call for systems that would keep up with new requirements. There was a need to change the type and style of equipment to keep up with the demands for more accurate information. Existing hardware was modified and new hardware was developed and designed to meet the new requirements of space travel of manned and unmanned orbital vehicles. This family of equipment had to withstand the rigors of space travel such as extremely high `G' forces, temperature changes and `O' gravity, while on earth we needed equipment to document launch of space vehicles as well as wind tunnel testing, rocket sled stands etc.. Some requirements were similar to those of launch vehicles, some were totally different and had other requirements, eventually they were all resolved. As electronic data systems became available NASA experimented with their use in data acquisition. This portion of this session will discuss the changes over the years and their effect on the acquisition of data, those that worked, as well as those that were a disappointment.

  20. Tools for 3D scientific visualization in computational aerodynamics at NASA Ames Research Center

    International Nuclear Information System (INIS)

    Bancroft, G.; Plessel, T.; Merritt, F.; Watson, V.


    Hardware, software, and techniques used by the Fluid Dynamics Division (NASA) for performing visualization of computational aerodynamics, which can be applied to the visualization of flow fields from computer simulations of fluid dynamics about the Space Shuttle, are discussed. Three visualization techniques applied, post-processing, tracking, and steering, are described, as well as the post-processing software packages used, PLOT3D, SURF (Surface Modeller), GAS (Graphical Animation System), and FAST (Flow Analysis software Toolkit). Using post-processing methods a flow simulation was executed on a supercomputer and, after the simulation was complete, the results were processed for viewing. It is shown that the high-resolution, high-performance three-dimensional workstation combined with specially developed display and animation software provides a good tool for analyzing flow field solutions obtained from supercomputers. 7 refs

  1. Simulation of Shuttle launch G forces and acoustic loads using the NASA Ames Research Center 20G centrifuge (United States)

    Shaw, T. L.; Corliss, J. M.; Gundo, D. P.; Mulenburg, G. M.; Breit, G. A.; Griffith, J. B.


    The high cost and long times required to develop research packages for space flight can often be offset by using ground test techniques. This paper describes a space shuttle launch and reentry simulating using the NASA Ames Research Center's 20G centrifuge facility. The combined G-forces and acoustic environment during shuttle launch and landing were simulated to evaluate the effect on a payload of laboratory rates. The launch G force and acoustic profiles are matched to actual shuttle launch data to produce the required G-forces and acoustic spectrum in the centrifuge test cab where the rats were caged on a free-swinging platform. For reentry, only G force is simulated as the aero-acoustic noise is insignificant compared to that during launch. The shuttle G-force profiles of launch and landing are achieved by programming the centrifuge drive computer to continuously adjust centrifuge rotational speed to obtain the correct launch and landing G forces. The shuttle launch acoustic environment is simulated using a high-power, low-frequency audio system. Accelerometer data from STS-56 and microphone data from STS-1 through STS-5 are used as baselines for the simulations. This paper provides a description of the test setup and the results of the simulation with recommendations for follow-on simulations.

  2. Current Background Noise Sources and Levels in the NASA Ames 40- by 80-Foot Wind Tunnel: A Status Report (United States)

    Allen, Christopher S.; Jaeger, Stephen; Soderman, Paul; Koga, Dennis (Technical Monitor)


    Background noise measurements were made of the acoustic environment in the National Full-Scale Aerodynamics Complex 40- by 80-Foot Wind Tunnel (40x80) at NASA Ames Research Center. The measurements were acquired subsequent to the 40x80 Aeroacoustic Modernization Project, which was undertaken to improve the anechoic characteristics of the 40x80's closed test section as well as reduce the levels of background noise in the facility. The resulting 40x80 anechoic environment was described by Soderman et. al., and the current paper describes the resulting 40x80 background noise, discusses the sources of the noise, and draws comparisons to previous 40x80 background noise levels measurements. At low wind speeds or low frequencies, the 40x80 background noise is dominated by the fan drive system. To obtain the lowest fan drive noise for a given tunnel condition, it is possible in the 40x80 to reduce the fans' rotational speed and adjust the fans' blade pitch, as described by Schmidtz et. al. This idea is not new, but has now been operationally implemented with modifications for increased power at low rotational speeds. At low to mid-frequencies and at higher wind speeds, the dominant noise mechanism was thought to be caused by the surface interface of the previous test section floor acoustic lining. In order to reduce this noise mechanism, the new test section floor lining was designed to resist the pumping of flow in and out of the space between the grating slats required to support heavy equipment. In addition, the lining/flow interface over the entire test section was designed to be smoother and quieter than the previous design. At high wind speeds or high frequencies, the dominant source of background noise in the 40x80 is believed to be caused by the response of the in-flow microphone probes (required by the nature of the closed test section) to the fluctuations in the freestream flow. The resulting background noise levels are also different for probes of various

  3. Developing the Infrared PAH Emission Bands Into Calibrated Probes of Astrophysical Conditions with The NASA Ames PAH IR Spectroscopic Database (United States)

    Boersma, Christiaan

    We propose to quantitatively calibrate the PAH band strength ratios that have been traditionally used as qualitative proxies of PAH properties and linking PAH observables with local astrophysical conditions, thus developing PAHs into quantitative probes of astronomical environments. This will culminate in a toolbox (calibration charts) that can be used by PAH experts and non-PAH experts alike to unlock the information hidden in PAH emission sources that are part of the Spitzer and ISO archives. Furthermore, the proposed work is critical to mine the treasure trove of information JWST will return as it will capture, for the first time, the complete mid-infrared (IR) PAH spectrum with fully resolved features, through a single aperture, and along single lines-of-sight; making it possible to fully extract the information contained in the PAH spectra. In short, the work proposed here represents a major step in enabling the astronomical PAH model to reach its full potential as a diagnostic of the physical and chemical conditions in objects spanning the Universe. Polycyclic aromatic hydrocarbons (PAHs), a common and important reservoir of accessible carbon across the Universe, play an intrinsic part in the formation of stars, planets and possibly even life itself. While most PAH spectra appear quite similar, they differ in detail and contain a wealth of untapped information. Thanks to recent advances in laboratory studies and computer-based calculations of PAH spectra, the majority of which have been made at NASA Ames, coupled with the astronomical modeling tools we have developed, we can interpret the spectral details at levels never before possible. This enables us to extract local physical conditions and track subtle changes in these conditions at levels previously impossible. Building upon the tools and paradigms developed as part of the publicly available NASA Ames PAH IR Spectroscopic Database (PAHdb;, the purpose of our proposed research is

  4. Piloted Evaluation of Modernized Limited Authority Control Laws in the NASA-Ames Vertical Motion Simulator (VMS) (United States)

    Sahasrabudhe, Vineet; Melkers, Edgar; Faynberg, Alexander; Blanken, Chris L.


    The UH-60 BLACK HAWK was designed in the 1970s, when the US Army primarily operated during the day in good visual conditions. Subsequently, the introduction of night-vision goggles increased the BLACK HAWK'S mission effectiveness, but the accident rate also increased. The increased accident rate is strongly tied to increased pilot workload as a result of a degradation in visual cues. Over twenty years of research in helicopter flight control and handling qualities has shown that these degraded handling qualities can be recovered by modifying the response type of the helicopter in low speed flight. Sikorsky Aircraft Corporation initiated a project under the National Rotorcraft Technology Center (NRTC) to develop modern flight control laws while utilizing the existing partial authority Stability Augmentation System (SAS) of the BLACK HAWK. This effort resulted in a set of Modernized Control Laws (MCLAWS) that incorporate rate command and attitude command response types. Sikorsky and the US Army Aeroflightdynamics Directorate (AFDD) conducted a piloted simulation on the NASA-Ames Vertical h4otion Simulator, to assess potential handling qualities and to reduce the risk of subsequent implementation and flight test of these modern control laws on AFDD's EH-60L helicopter. The simulation showed that Attitude Command Attitude Hold control laws in pitch and roll improve handling qualities in the low speed flight regime. These improvements are consistent across a range of mission task elements and for both good and degraded visual environments. The MCLAWS perform better than the baseline UH-60A control laws in the presence of wind and turbulence. Finally, while the improved handling qualities in the pitch and roll axis allow the pilot to pay more attention to the vertical axis and hence altitude performance also improves, it is clear from pilot comments and altitude excursions that the addition of an Altitude Hold function would further reduce workload and improve overall

  5. The NASA Space Place: A Plethora of Games, Projects, and Fun Facts for Celebrating Astronomy (United States)

    Leon, N. J.; Fisher, D. K.


    The Space Place is a unique NASA education and public outreach program. It includes a NASA website ( in English and Spanish that targets elementary age children with appealing, content- rich STEM material on space science, Earth science, and technology. The site features science and/or technology content related to, so far, over 40 NASA missions. This overall program, as well as special efforts planned for IYA2009, strongly support many of the objectives of IYA. Some of these are: 1. Stimulate interest in astronomy and science, especially among young people and in audiences not normally reached. 2. Increase scientific awareness. 3. Support and improve formal and informal science education. 4. Provide a contemporary image of science and scientists. 5. Facilitate new astronomy education networks and strengthen existing ones. 6. Improve the gender-balanced representation of scientists at all levels and promote greater involvement of underrepresented groups. The Space Place program has cultivated a large network of community partners (Obj. 5), including museums, libraries, and planetariums, as well as a large network of avocational astronomy societies. We send the community partners monthly mailings of the latest NASA materials for their "NASA Space Place" display boards (Obj. 1, 2, 3, 5). The astronomy societies receive original articles with the latest "insider" news on NASA missions for publication in their newsletters or on their websites (Obj. 2, 5). Through these leveraged partnerships, we reach a large audience of children; parents; formal and informal educators; rural, minority, and otherwise underserved audiences (Obj. 1, 6); and avocational astronomers, many of whom work with children and the general public in the classroom or at special events (Obj. 2, 3). Supporting Obj. 4, are the "Space Place Live" cartoon "talk show" episodes, For IYA 2009, we will specifically prepare our partners to plan and carry

    Joe Mambretti Richard desJardins


    A new generation of optical networking services and technologies is rapidly changing the world of communications. National and international networks are implementing optical services to supplement traditional packet routed services. On September 12-14, 2005, the Optical Network Testbeds Workshop 2 (ONT2), an invitation-only forum hosted by the NASA Research and Engineering Network (NREN) and co-sponsored by the Department of Energy (DOE), was held at NASA Ames Research Center in Mountain View, California. The aim of ONT2 was to help the Federal Large Scale Networking Coordination Group (LSN) and its Joint Engineering Team (JET) to coordinate testbed and network roadmaps describing agency and partner organization views and activities for moving toward next generation communication services based on leading edge optical networks in the 3-5 year time frame. ONT2 was conceived and organized as a sequel to the first Optical Network Testbeds Workshop (ONT1, August 2004, ONT1 resulted in a series of recommendations to LSN. ONT2 was designed to move beyond recommendations to agree on a series of “actionable objectives” that would proactively help federal and partner optical network testbeds and advanced research and education (R&E) networks to begin incorporating technologies and services representing the next generation of advanced optical networks in the next 1-3 years. Participants in ONT2 included representatives from innovative prototype networks (Panel A), basic optical network research testbeds (Panel B), and production R&D networks (Panels C and D), including “JETnets,” selected regional optical networks (RONs), international R&D networks, commercial network technology and service providers (Panel F), and senior engineering and R&D managers from LSN agencies and partner organizations. The overall goal of ONT2 was to identify and coordinate short and medium term activities and milestones for researching, developing, identifying

  7. Model Deformation Measurements of Sonic Boom Models in the NASA Ames 9- by 7-Ft Supersonic Wind Tunnel (United States)

    Schairer, Edward T.; Kushner, Laura K.; Garbeff, Theodore J.; Heineck, James T.


    The deformations of two sonic-boom models were measured by stereo photogrammetry during tests in the 9- by 7-Ft Supersonic Wind Tunnel at NASA Ames Research Center. The models were geometrically similar but one was 2.75 times as large as the other. Deformation measurements were made by simultaneously imaging the upper surfaces of the models from two directions by calibrated cameras that were mounted behind windows of the test section. Bending and twist were measured at discrete points using conventional circular targets that had been marked along the leading and trailing edges of the wings and tails. In addition, continuous distributions of bending and twist were measured from ink speckles that had been applied to the upper surfaces of the model. Measurements were made at wind-on (M = 1.6) and wind-off conditions over a range of angles of attack between 2.5 deg. and 5.0 deg. At each condition, model deformation was determined by comparing the wind-off and wind-on coordinates of each measurement point after transforming the coordinates to reference coordinates tied to the model. The necessary transformations were determined by measuring the positions of a set of targets on the rigid center-body of the models whose model-axes coordinates were known. Smoothly varying bending and twist measurements were obtained at all conditions. Bending displacements increased in proportion to the square of the distance to the centerline. Maximum deflection of the wingtip of the larger model was about 5 mm (2% of the semispan) and that of the smaller model was 0.9 mm (1% of the semispan). The change in wing twist due to bending increased in direct proportion to distance from the centerline and reached a (absolute) maximum of about -1? at the highest angle of attack for both models. The measurements easily resolved bending displacements as small as 0.05 mm and bending-induced changes in twist as small as 0.05 deg.

    A significantly updated version of the NASA Ames PAH IR Spectroscopic Database, the first major revision since its release in 2010, is presented. The current version, version 2.00, contains 700 computational and 75 experimental spectra compared, respectively, with 583 and 60 in the initial release. The spectra span the 2.5-4000 μm (4000-2.5 cm{sup -1}) range. New tools are available on the site that allow one to analyze spectra in the database and compare them with imported astronomical spectra as well as a suite of IDL object classes (a collection of programs utilizing IDL's object-oriented programming capabilities) that permit offline analysis called the AmesPAHdbIDLSuite. Most noteworthy among the additions are the extension of the computational spectroscopic database to include a number of significantly larger polycyclic aromatic hydrocarbons (PAHs), the ability to visualize the molecular atomic motions corresponding to each vibrational mode, and a new tool that allows one to perform a non-negative least-squares fit of an imported astronomical spectrum with PAH spectra in the computational database. Finally, a methodology is described in the Appendix, and implemented using the AmesPAHdbIDLSuite, that allows the user to enforce charge balance during the fitting procedure.

  9. A Tale of Two Small Business Grants: The Best of Times, the Worst of Times from the NASA Ames Small Business Innovative Research (SBIR) Program (United States)

    Kojiro, Daniel R.; Lee, Geoffrey S.


    The purposes of the SBIR Program are to: stimulate technological innovation in the private sector; strengthen the role of Small Business Concerns (SBCs) in meeting Federal research and development needs; increase the commercial application of these research results; and encourage participation of socially and economically disadvantaged persons and women-owned small businesses. The process can be highly rewarding, providing the small business with resources to pursue research and development with a focus on providing NASA with new and advanced capabilities. We present two examples of how the NASA Ames SBIR Program has addressed these purposes, nurturing innovative ideas from small, businesses into commercially viable products that also address analytical needs in space research. These examples, from the Science Instruments for Conducting Solar System Exploration Subtopic, describe the journey from innovative concept to analytical instrument, one successful and one hampered by numerous roadblocks (including some international intrigue}.

  11. The NASA Ames PAH IR Spectroscopic Database: Computational Version 3.00 with Updated Content and the Introduction of Multiple Scaling Factors (United States)

    Bauschlicher, Charles W., Jr.; Ricca, A.; Boersma, C.; Allamandola, L. J.


    Version 3.00 of the library of computed spectra in the NASA Ames PAH IR Spectroscopic Database (PAHdb) is described. Version 3.00 introduces the use of multiple scale factors, instead of the single scaling factor used previously, to align the theoretical harmonic frequencies with the experimental fundamentals. The use of multiple scale factors permits the use of a variety of basis sets; this allows new PAH species to be included in the database, such as those containing oxygen, and yields an improved treatment of strained species and those containing nitrogen. In addition, the computed spectra of 2439 new PAH species have been added. The impact of these changes on the analysis of an astronomical spectrum through database-fitting is considered and compared with a fit using Version 2.00 of the library of computed spectra. Finally, astronomical constraints are defined for the PAH spectral libraries in PAHdb.

  12. Proposed Use of the NASA Ames Nebula Cloud Computing Platform for Numerical Weather Prediction and the Distribution of High Resolution Satellite Imagery (United States)

    Limaye, Ashutosh S.; Molthan, Andrew L.; Srikishen, Jayanthi


    The development of the Nebula Cloud Computing Platform at NASA Ames Research Center provides an open-source solution for the deployment of scalable computing and storage capabilities relevant to the execution of real-time weather forecasts and the distribution of high resolution satellite data to the operational weather community. Two projects at Marshall Space Flight Center may benefit from use of the Nebula system. The NASA Short-term Prediction Research and Transition (SPoRT) Center facilitates the use of unique NASA satellite data and research capabilities in the operational weather community by providing datasets relevant to numerical weather prediction, and satellite data sets useful in weather analysis. SERVIR provides satellite data products for decision support, emphasizing environmental threats such as wildfires, floods, landslides, and other hazards, with interests in numerical weather prediction in support of disaster response. The Weather Research and Forecast (WRF) model Environmental Modeling System (WRF-EMS) has been configured for Nebula cloud computing use via the creation of a disk image and deployment of repeated instances. Given the available infrastructure within Nebula and the "infrastructure as a service" concept, the system appears well-suited for the rapid deployment of additional forecast models over different domains, in response to real-time research applications or disaster response. Future investigations into Nebula capabilities will focus on the development of a web mapping server and load balancing configuration to support the distribution of high resolution satellite data sets to users within the National Weather Service and international partners of SERVIR.

  13. Aeroacoustic Study of a 26%-Scale Semispan Model of a Boeing 777 Wing in the NASA Ames 40- by 80-Foot Wind Tunnel (United States)

    Horne, W. Clifton; Burnside, Nathan J.; Soderman, Paul T.; Jaeger, Stephen M.; Reinero, Bryan R.; James, Kevin D.; Arledge, Thomas K.


    An acoustic and aerodynamic study was made of a 26%-scale unpowered Boeing 777 aircraft semispan model in the NASA Ames 40- by 80-Foot Wind Tunnel for the purpose of identifying and attenuating airframe noise sources. Simulated approach and landing configurations were evaluated at Mach numbers between 0.12 and 0.24. Cruise configurations were evaluated at Mach numbers between 0.24 and 0.33. The research team used two Ames phased-microphone arrays, a large fixed array and a small traversing array, mounted under the wing to locate and compare various noise sources in the wing high-lift system and landing gear. Numerous model modifications and noise alleviation devices were evaluated. Simultaneous with acoustic measurements, aerodynamic forces were recorded to document aircraft conditions and any performance changes caused by the geometric modifications. Numerous airframe noise sources were identified that might be important factors in the approach and landing noise of the full-scale aircraft. Several noise-control devices were applied to each noise source. The devices were chosen to manipulate and control, if possible, the flow around the various tips and through the various gaps of the high-lift system so as to minimize the noise generation. Fences, fairings, tip extensions, cove fillers, vortex generators, hole coverings, and boundary-layer trips were tested. In many cases, the noise-control devices eliminated noise from some sources at specific frequencies. When scaled to full-scale third-octave bands, typical noise reductions ranged from 1 to 10 dB without significant aerodynamic performance loss.

  14. Stereo Photogrammetry Measurements of the Position and Attitude of a Nozzle-Plume/Shock-Wave Interaction Model in the NASA Ames 9- by 7-Ft Supersonic Wind Tunnel (United States)

    Schairer, Edward T.; Kushner, Laura K.; Drain, Bethany A.; Heineck, James T.; Durston, Donald A.


    Stereo photogrammetry was used to measure the position and attitude of a slender body of revolution during nozzle-plume/shock-wave interaction tests in the NASA Ames 9- by 7-Ft Supersonic Wind Tunnel. The model support system was designed to allow the model to be placed at many locations in the test section relative to a pressure rail on one sidewall. It included a streamwise traverse as well as a thin blade that offset the model axis from the sting axis. With these features the support system was more flexible than usual resulting in higher-than-usual uncertainty in the position and attitude of the model. Also contributing to this uncertainty were the absence of a balance, so corrections for sting deflections could not be applied, and the wings-vertical orientation of the model, which precluded using a gravity-based accelerometer to measure pitch angle. Therefore, stereo photogrammetry was chosen to provide independent measures of the model position and orientation. This paper describes the photogrammetry system and presents selected results from the test.

  16. Plans for Testing the NREL Unsteady Aerodynamics Experiment 10m Diameter HAWT in the NASA Ames Wind Tunnel: Minutes, Conclusions, and Revised Text Matrix from the 1st Science Panel Meeting

    Energy Technology Data Exchange (ETDEWEB)

    Simms, D.; Schreck, S.; Hand, M.; Fingersh, L.; Cotrell, J.; Pierce, K.; Robinson, M.


    Currently, the NREL Unsteady Aerodynamics Experiment (UAE) research turbine is scheduled to enter the NASA Ames 80-ft x 120-ft wind tunnel in early 2000. To prepare for this 3-week test, a Science Panel meeting was convened at the National Wind Technology Center (NWTC) in October 1998. During this meeting, the Science Panel and representatives from the wind energy community provided numerous detailed recommendations regarding test activities and priorities. The Unsteady Aerodynamics team of the NWTC condensed this guidance and drafted a detailed test plan. This test plan represents an attempt to balance diverse recommendations received from the Science Panel meeting, while taking into account multiple constraints imposed by the UAE research turbine, the NASA Ames 80-ft x 120-ft wind tunnel, and other sources. The NREL-NASA Ames wind tunnel tests will primarily be focused on obtaining rotating blade pressure data. NREL has been making these types of measurements since 1987 and has considerable experience in doing so. The purpose of this wind tunnel test is to acquire accurate quantitative aerodynamic and structural measurements, on a wind turbine that is geometrically and dynamically representative of full-scale machines, in an environment free from pronounced inflow anomalies. These data will be exploited to develop and validate enhanced engineering models for designing and analyzing advanced wind energy machines.

  17. The Mars Dust Cycle: Investigating the Effects of Radiatively Active Water Ice Clouds on Surface Stresses and Dust Lifting Potential with the NASA Ames Mars General Circulation Model (United States)

    Kahre, Melinda A.; Hollingsworth, Jeffery


    The dust cycle is a critically important component of Mars' current climate system. Dust is present in the atmosphere of Mars year-round but the dust loading varies with season in a generally repeatable manner. Dust has a significant influence on the thermal structure of the atmosphere and thus greatly affects atmospheric circulation. The dust cycle is the most difficult of the three climate cycles (CO2, water, and dust) to model realistically with general circulation models. Until recently, numerical modeling investigations of the dust cycle have typically not included the effects of couplings to the water cycle through cloud formation. In the Martian atmosphere, dust particles likely provide the seed nuclei for heterogeneous nucleation of water ice clouds. As ice coats atmospheric dust grains, the newly formed cloud particles exhibit different physical and radiative characteristics. Thus, the coupling between the dust and water cycles likely affects the distributions of dust, water vapor and water ice, and thus atmospheric heating and cooling and the resulting circulations. We use the NASA Ames Mars GCM to investigate the effects of radiatively active water ice clouds on surface stress and the potential for dust lifting. The model includes a state-of-the-art water ice cloud microphysics package and a radiative transfer scheme that accounts for the radiative effects of CO2 gas, dust, and water ice clouds. We focus on simulations that are radiatively forced by a prescribed dust map, and we compare simulations that do and do not include radiatively active clouds. Preliminary results suggest that the magnitude and spatial patterns of surface stress (and thus dust lifting potential) are substantial influenced by the radiative effects of water ice clouds.

  18. Biological Visualization, Imaging and Simulation(Bio-VIS) at NASA Ames Research Center: Developing New Software and Technology for Astronaut Training and Biology Research in Space (United States)

    Smith, Jeffrey


    The Bio- Visualization, Imaging and Simulation (BioVIS) Technology Center at NASA's Ames Research Center is dedicated to developing and applying advanced visualization, computation and simulation technologies to support NASA Space Life Sciences research and the objectives of the Fundamental Biology Program. Research ranges from high resolution 3D cell imaging and structure analysis, virtual environment simulation of fine sensory-motor tasks, computational neuroscience and biophysics to biomedical/clinical applications. Computer simulation research focuses on the development of advanced computational tools for astronaut training and education. Virtual Reality (VR) and Virtual Environment (VE) simulation systems have become important training tools in many fields from flight simulation to, more recently, surgical simulation. The type and quality of training provided by these computer-based tools ranges widely, but the value of real-time VE computer simulation as a method of preparing individuals for real-world tasks is well established. Astronauts routinely use VE systems for various training tasks, including Space Shuttle landings, robot arm manipulations and extravehicular activities (space walks). Currently, there are no VE systems to train astronauts for basic and applied research experiments which are an important part of many missions. The Virtual Glovebox (VGX) is a prototype VE system for real-time physically-based simulation of the Life Sciences Glovebox where astronauts will perform many complex tasks supporting research experiments aboard the International Space Station. The VGX consists of a physical display system utilizing duel LCD projectors and circular polarization to produce a desktop-sized 3D virtual workspace. Physically-based modeling tools (Arachi Inc.) provide real-time collision detection, rigid body dynamics, physical properties and force-based controls for objects. The human-computer interface consists of two magnetic tracking devices

  19. Comparison of acoustic data from a 102 mm conic nozzle as measured in the RAE 24-foot wind tunnel and the NASA Ames 40- by 80-foot wind tunnel (United States)

    Atencio, A., Jr.; Mckie, J.


    A cooperative program between the Royal Aircraft Establishment (RAE), England, and the NASA Ames Research Center was initiated to compare acoustic measurements made in the RAE 24-foot wind tunnel and in the Ames 40- by 80-foot wind tunnel. The acoustic measurements were made in both facilities using the same 102 mm conical nozzle supplied by the RAE. The nozzle was tested by each organization using its respective jet test rig. The mounting hardware and nozzle exit conditions were matched as closely as possible. The data from each wind tunnel were independently analyzed by the respective organization. The results from these tests show good agreement. In both facilities, interference with acoustic measurement is evident at angles in the forward quadrant.

The LSDA will soon be archiving data and tissues samples collected on the next generation of commercial vehicles; e.g., SpaceX & Cygnus Commercial Cargo Craft. To date over 375 rodent flight experiments with translational application have been archived by the Ames LSDA office. This knowledge base of fundamental research can be used to understand mechanisms that affect higher organisms in microgravity and help define additional research whose results could lead the way to closing gaps identified by the Human Research Program (HRP). This poster will highlight Ames contribution to the existing knowledge base and how the LSDA can be a resource to help answer the questions surrounding human health in long duration space exploration. In addition, it will illustrate how this body of knowledge was utilized to further our understanding of how space flight affects the human system and the ability to develop countermeasures that negate the deleterious effects of space flight. The Ames Life Sciences Data Archive (ALSDA) includes current descriptions of over 700 experiments conducted aboard the Shuttle, International Space Station (ISS), NASA/MIR, Bion/Cosmos, Gemini, Biosatellites, Apollo, Skylab, Russian Foton, and ground bed rest studies. Research areas cover Behavior and Performance, Bone and Calcium Physiology, Cardiovascular Physiology, Cell and Molecular Biology, Chronobiology, Developmental Biology, Endocrinology, Environmental Monitoring, Gastrointestinal Physiology, Hematology, Immunology, Life Support System, Metabolism and Nutrition, Microbiology, Muscle Physiology, Neurophysiology, Pharmacology, Plant Biology, Pulmonary Physiology, Radiation Biology, Renal, Fluid and Electrolyte Physiology, and Toxicology.

  7. Flight and full-scale wind-tunnel comparison of pressure distributions from an F-18 aircraft at high angles of attack. [Conducted in NASA Ames Research Center's 80 by 120 ft wind tunnel (United States)

    Fisher, David F.; Lanser, Wendy R.


    Pressure distributions were obtained at nearly identical fuselage stations and wing chord butt lines in flight on the F-18 HARV at NASA Dryden Flight Research Center and in the NASA Ames Research Center's 80 by 120 ft wind tunnel on a full-scale F/A-18 aircraft. The static pressures were measured at the identical five stations on the forebody, three stations on the left and right leading-edge extensions, and three spanwise stations on the wing. Comparisons of the flight and wind-tunnel pressure distributions were made at alpha = 30 deg, 45 deg, and 60 deg/59 deg. In general, very good agreement was found. Minor differences were noted at the forebody at alpha = 45 deg and 60 deg in the magnitude of the vortex footprints and a Mach number effect was noted at the leading-edge extension at alpha = 30 deg. The inboard leading edge flap data from the wind tunnel at alpha = 59 deg showed a suction peak that did not appear in the flight data. This was the result of a vortex from the corner of the leading edge flap whose path was altered by the lack of an engine simulation in the wind tunnel.

  8. An automated, open-source (NASA Ames Stereo Pipeline) workflow for mass production of high-resolution DEMs from commercial stereo satellite imagery: Application to mountain glacies in the contiguous US (United States)

    Shean, D. E.; Arendt, A. A.; Whorton, E.; Riedel, J. L.; O'Neel, S.; Fountain, A. G.; Joughin, I. R.


    We adapted the open source NASA Ames Stereo Pipeline (ASP) to generate digital elevation models (DEMs) and orthoimages from very-high-resolution (VHR) commercial imagery of the Earth. These modifications include support for rigorous and rational polynomial coefficient (RPC) sensor models, sensor geometry correction, bundle adjustment, point cloud co-registration, and significant improvements to the ASP code base. We outline an automated processing workflow for 0.5 m GSD DigitalGlobe WorldView-1/2/3 and GeoEye-1 along-track and cross-track stereo image data. Output DEM products are posted at 2, 8, and 32 m with direct geolocation accuracy of process individual stereo pairs on a local workstation, the methods presented here were developed for large-scale batch processing in a high-performance computing environment. We have leveraged these resources to produce dense time series and regional mosaics for the Earth's ice sheets. We are now processing and analyzing all available 2008-2016 commercial stereo DEMs over glaciers and perennial snowfields in the contiguous US. We are using these records to study long-term, interannual, and seasonal volume change and glacier mass balance. This analysis will provide a new assessment of regional climate change, and will offer basin-scale analyses of snowpack evolution and snow/ice melt runoff for water resource applications.

  16. Performing Belonging, celebrating invisibility?

    DEFF Research Database (Denmark)

    Juul, Kristine


    Serbian migrants living transnational lives consciously or unconsciously move between visibility and invisibility in their performance of migrant success stories. A case in point are public festivals, performed to make visible migrants’ successful inclusion in Danish society, i.e. celebrating...... invisibility. Meanwhile, other celebrations are consciously relegated to the invisible confines of the Serbian homeland. This article analyses celebrations in Denmark and in Serbia and shows how visible displays of ethnicity and difference tend to turn into easily palatable heritage versions of Serbian culture...... when performed in a Danish context. In turn, the visibility acquired through celebrations of migrants’ belonging in their homeland is inclined to render invisible those who did not take part in the migration experience....

This article argues...... that celebrities are acting as other elite actors in international affairs: investing considerable capital into processes that are highly political. It traces the emergence and practices of the elite politics of celebrities in North-South relations, an evolution made possible by recent changes in aid practices......, media, and NGOs, then considers exemplary cases of Angelina Jolie in Burma, Ben Affleck in the Democractic Republic of Congo, and Madonna in Malawi. These celebrity practices as diplomats, experts, and humanitarians in international affairs illustrate the diverse and contradictory forms of engagement...

    Karcz, J. S.; Bowling, D.; Cornelison, C.; Parrish, A.; Perez, A.; Raiche, G.; Wiens, J.-P.


    The Ames Vertical Gun Range (AVGR) is a national facility for conducting laboratory- scale investigations of high-speed impact processes. It provides a set of light-gas, powder, and compressed gas guns capable of accelerating projectiles to speeds up to 7 km s(exp -1). The AVGR has a unique capability to vary the angle between the projectile-launch and gravity vectors between 0 and 90 deg. The target resides in a large chamber (diameter approximately 2.5 m) that can be held at vacuum or filled with an experiment-specific atmosphere. The chamber provides a number of viewing ports and feed-throughs for data, power, and fluids. Impacts are observed via high-speed digital cameras along with investigation-specific instrumentation, such as spectrometers. Use of the range is available via grant proposals through any Planetary Science Research Program element of the NASA Research Opportunities in Space and Earth Sciences (ROSES) calls. Exploratory experiments (one to two days) are additionally possible in order to develop a new proposal.

  7. Ames Optimized TCA Configuration (United States)

    Cliff, Susan E.; Reuther, James J.; Hicks, Raymond M.


    Configuration design at Ames was carried out with the SYN87-SB (single block) Euler code using a 193 x 49 x 65 C-H grid. The Euler solver is coupled to the constrained (NPSOL) and the unconstrained (QNMDIF) optimization packages. Since the single block grid is able to model only wing-body configurations, the nacelle/diverter effects were included in the optimization process by SYN87's option to superimpose the nacelle/diverter interference pressures on the wing. These interference pressures were calculated using the AIRPLANE code. AIRPLANE is an Euler solver that uses a unstructured tetrahedral mesh and is capable of computations about arbitrary complete configurations. In addition, the buoyancy effects of the nacelle/diverters were also included in the design process by imposing the pressure field obtained during the design process onto the triangulated surfaces of the nacelle/diverter mesh generated by AIRPLANE. The interference pressures and nacelle buoyancy effects are added to the final forces after each flow field calculation. Full details of the (recently enhanced) ghost nacelle capability are given in a related talk. The pseudo nacelle corrections were greatly improved during this design cycle. During the Ref H and Cycle 1 design activities, the nacelles were only translated and pitched. In the cycle 2 design effort the nacelles can translate vertically, and pitch to accommodate the changes in the lower surface geometry. The diverter heights (between their leading and trailing edges) were modified during design as the shape of the lower wing changed, with the drag of the diverter changing accordingly. Both adjoint and finite difference gradients were used during optimization. The adjoint-based gradients were found to give good direction in the design space for configurations near the starting point, but as the design approached a minimum, the finite difference gradients were found to be more accurate. Use of finite difference gradients was limited by the

  8. Celebrity and contemporary context

    Directory of Open Access Journals (Sweden)

    Paula Guimarães Simões


    Full Text Available This paper discusses the hermeneutic power of a celebrity (seen from the concept of event, seeking to understand what it reveals about the contemporary context. Based on this premise, we attempt to recognize some aspects of contemporary social life that emerge from the trajectory of a specific celebrity: the former soccer player Ronaldo Fenômeno. This analysis brings to light the hermeneutic power of Ronaldo, i.e., how his life story reveals characteristics of contemporary social life. Individualism, machismo, emphasis on a heteronormative ideal, shifts in the construction of romantic relationships, and the overlapping spheres of public and private life, are some important aspects of contemporary society revealed by this analysis.

    Mersid Poturak


    Full Text Available The instrument of celebrity endorsement has nowadays become a pervasive element in advertising and communication management. It is unanimously accepted that celebrity endorsement can grant extraordinary characteristics to a product or service that may have lacked otherwise. The great number of celebrities endorsing brands has been increasing over the past decades. The purpose of this study is to examine perceptions of the student population in Bosnia and Herzegovina (hereafter named BiH about the celebrity endorsement. Questionnaire is designed and used to survey a randomly selected sample of university students and 125 usable responses were obtained. During the research, five hypotheses have been tested. Data were analyzed by performing descriptive statistics and Chi-Square test. Chi-Square test was used to analyze relationship between nationality of respondents and factors that influence decision of choosing celebrity endorser by firm. Findings show that students perceive celebrities as a very important factor in advertisements.

    Dr. Alan Chodos; Elizabeth A. Rogan


    LaserFest was the yearlong celebration, during 2010, of the 50th anniversary of the demonstration of the first working laser. The goals of LaserFest were: to highlight the impact of the laser in its manifold commercial, industrial and medical applications, and as a tool for ongoing scientific research; to use the laser as one example that illustrates, more generally, the route from scientific innovation to technological application; to use the laser as a vehicle for outreach, to stimulate interest among students and the public in aspects of physical science; to recognize and honor the pioneers who developed the laser and its many applications; to increase awareness among policymakers of the importance of R&D funding as evidenced by such technology as lasers. One way in which LaserFest sought to meet its goals was to encourage relevant activities at a local level all across the country -- and also abroad -- that would be identified with the larger purposes of the celebration and would carry the LaserFest name. Organizers were encouraged to record and advertise these events through a continually updated web-based calendar. Four projects were explicitly detailed in the proposals: 1) LaserFest on the Road; 2) Videos; 3) Educational material; and 4) Laser Days.

  17. Celebrating women in physics

    CERN Multimedia

    Rolf Heuer


    Next Monday the 8th of March is International Women’s Day. In an ideal world, there would be no need for such an event – equality would be taken as read. But since the world is not there yet, let’s take the opportunity to celebrate women in physics, and indeed the full cultural diversity of our field. Perceived as a discipline dominated by men, reality has been diverging from that perception for a long time. Today at CERN, women play key roles in every aspect of the Organization’s activities.   On Women’s Day, we will be sending a clear message to all young women interested in science and engineering that this is also a field for them. In the CERN Control Centre, half of the Engineers-in-Charge who take responsibility for operating the world’s most powerful particle accelerator are women. In the experiments, in all CERN departments and in the management, women are increasingly represented. That’s because at CERN, and in particl...

  18. IYL 2015 celebrations (United States)

    Adams, Aaron Morgan; Beasley, Gary


    The International Year of Light 2015 was designed to raise awareness of light sciences. In order to raise awareness, events were encouraged to get the public involved. Both Central Carolina Community College (CCCC) and Indian River State College (IRSC) held a total of three lectures in 2015 celebrating the IYL 2015. IRSC hosted lectures on March 6th and June 11th. CCCC hosted a lecture on November 17th. These lectures drew a total of over 400 attendees. Lectures revolved around their own unique themes relating to light sciences in industry and academia. With great support from Laser-Tec, SPIE, and NSF, these lectures were successful at exposing and advertising the optics field to the public, as well as promising up-and-coming students. These lectures hosted several keynote speakers on behalf of both industry and academia. The speakers were successful at keeping the audience engaged through presentations and question-and-answer sessions. In addition, lab tours allowed the attendees a chance to see the programs in action. Many takeaways will prove to be invaluable when pursuing such events in the future. This paper will not only speak to the tremendous success of these lectures, but will take an honest look at the areas for improvement. It is important to note that independent events can be held for the expansion of local programs leading to national, if not global, increase in communal awareness and participation. These events will serve as a continuation for what the IYL 2015 was designed.

  20. Static and wind tunnel near-field/far-field jet noise measurements from model scale single-flow base line and suppressor nozzles. Summary report. [conducted in the Boeing large anechoic test chamber and the NASA-Ames 40by 80-foot wind tunnel (United States)

    Jaeck, C. L.


    A test program was conducted in the Boeing large anechoic test chamber and the NASA-Ames 40- by 80-foot wind tunnel to study the near- and far-field jet noise characteristics of six baseline and suppressor nozzles. Static and wind-on noise source locations were determined. A technique for extrapolating near field jet noise measurements into the far field was established. It was determined if flight effects measured in the near field are the same as those in the far field. The flight effects on the jet noise levels of the baseline and suppressor nozzles were determined. Test models included a 15.24-cm round convergent nozzle, an annular nozzle with and without ejector, a 20-lobe nozzle with and without ejector, and a 57-tube nozzle with lined ejector. The static free-field test in the anechoic chamber covered nozzle pressure ratios from 1.44 to 2.25 and jet velocities from 412 to 594 m/s at a total temperature of 844 K. The wind tunnel flight effects test repeated these nozzle test conditions with ambient velocities of 0 to 92 m/s.

This book examines what the diverse roster of celebrity humanitarians are actually doing in and across North and South contexts.

  13. Celebrity endorsements of cancer screening. (United States)

    Larson, Robin J; Woloshin, Steven; Schwartz, Lisa M; Welch, H Gilbert


    Celebrities often promote cancer screening by relating personal anecdotes about their own diagnosis or that of a loved one. We used data obtained from a random-digit dialing survey conducted in the United States from December 2001 through July 2002 to examine the extent to which adults of screening age without a history of cancer had seen or heard or been influenced by celebrity endorsements of screening mammography, prostate-specific antigen (PSA) testing, or sigmoidoscopy or colonoscopy. The survey response rate was 72% among those known to be eligible and 51% among potentially eligible people accounting for those who could not be contacted. A total of 360 women aged 40 years or older and 140 men aged 50 years or older participated in the survey. Most respondents reported they "had seen or heard a celebrity talk about" mammography (73% of women aged 40 years or older), PSA testing (63% of men aged 50 years or older), or sigmoidoscopy or colonoscopy (52% of adults aged 50 years or older). At least one-fourth of respondents who had seen or heard a celebrity endorsement said that the endorsement made them more likely to undergo mammography (25%), PSA testing (31%), or sigmoidoscopy or colonoscopy (37%).

  16. The effectiveness of celebrities in conservation marketing.

    Directory of Open Access Journals (Sweden)

    Elizabeth Duthie

    Full Text Available Celebrities are frequently used in conservation marketing as a tool to raise awareness, generate funding and effect behaviour change. The importance of evaluating effectiveness is widely recognised in both marketing and conservation but, to date, little research into the effectiveness of celebrity endorsement as a tool for conservation marketing has been published. Using a combination of interviews and an online choice survey instrument, we investigated the extent to which a sample of UK-based conservation organisations, and other charities, evaluate their own usage of celebrity endorsement, and then carried out an experimental evaluation of a hypothetical marketing campaign. This experiment compared participants' willingness-to-engage (WTE with, and recall of, a conservation message presented in versions of an advert featuring one of three prominent UK celebrities (David Beckham, Chris Packham or HRH Prince William or a non-celebrity control treatment (featuring Crawford Allan, a director of TRAFFIC USA. We find that the organisations we interviewed did not routinely evaluate their marketing campaigns featuring celebrities. Furthermore, our experiment provides evidence that celebrity endorsement can produce both positive and negative effects. Participants were more willing to engage when presented with an advert featuring one of the three celebrities than the non-celebrity control, and WTE varied according to the characteristics of the celebrity and the respondent. However, celebrities were less effective at generating campaign message recall than non-celebrities. These findings suggest that celebrity endorsement should be used carefully. Further work is required to fully understand the role celebrity endorsers can play in conservation but, drawing on best practice from the field of marketing, this study introduces an approach to evaluation which could be applied more widely to improve the effectiveness of conservation marketing.

  18. Kids Sell: Celebrity Kids’ Right to Privacy

    Directory of Open Access Journals (Sweden)

    Seong Choul Hong


    Full Text Available The lives of celebrities are often spotlighted in the media because of their newsworthiness; however, many celebrities argue that their right to privacy is often infringed upon. Concerns about celebrity privacy are not limited to the celebrities themselves and often expand to their children. As a result of their popularity, public interest has pushed paparazzi and journalists to pursue trivial and private details about the lives of both celebrities and their children. This paper investigates conflicting areas where the right to privacy and the right to know collide when dealing with the children of celebrities. In general, the courts have been unsympathetic to celebrity privacy claims, noting their newsworthiness and self-promoted characteristic. Unless the press violates news-gathering ethics or torts, the courts will often rule in favor of the media. However, the story becomes quite different when related to an infringement on the privacy of celebrities’ children. This paper argues that all children have a right to protect their privacy regardless of their parents’ social status. Children of celebrities should not be exempt to principles of privacy just because their parents are a celebrity. Furthermore, they should not be exposed by the media without the voluntary consent of their legal patrons. That is, the right of the media to publish and the newsworthiness of children of celebrities must be restrictedly acknowledged.

  19. Consolidating NASA's Arc Jets (United States)

    Balboni, John A.; Gokcen, Tahir; Hui, Frank C. L.; Graube, Peter; Morrissey, Patricia; Lewis, Ronald


    The paper describes the consolidation of NASA's high powered arc-jet testing at a single location. The existing plasma arc-jet wind tunnels located at the Johnson Space Center were relocated to Ames Research Center while maintaining NASA's technical capability to ground-test thermal protection system materials under simulated atmospheric entry convective heating. The testing conditions at JSC were reproduced and successfully demonstrated at ARC through close collaboration between the two centers. New equipment was installed at Ames to provide test gases of pure nitrogen mixed with pure oxygen, and for future nitrogen-carbon dioxide mixtures. A new control system was custom designed, installed and tested. Tests demonstrated the capability of the 10 MW constricted-segmented arc heater at Ames meets the requirements of the major customer, NASA's Orion program. Solutions from an advanced computational fluid dynamics code were used to aid in characterizing the properties of the plasma stream and the surface environment on the calorimeters in the supersonic flow stream produced by the arc heater.

The research tests “the old model of celebrity endorsement” (Chahal, 2013) in a new context using new media. Despite the ample literature (Erdogan, 1999; Keller, 2008) on celebrity appeal, the impact of unpaid messages remains underexplored. The paper addresses this gap, confirming that unpaid messages in relation to...

  4. Celebrity Patients, VIPs, and Potentates. (United States)

    Groves, James E.; Dunderdale, Barbara A.; Stern, Theodore A.


    BACKGROUND: During the second half of the 20th century, the literature on the doctor-patient relationship mainly dealt with the management of "difficult" (personality-disordered) patients. Similar problems, however, surround other types of "special" patients. METHOD: An overview and analysis of the literature were conducted. As a result, such patients can be subcategorized by their main presentations; each requires a specific management strategy. RESULTS: Three types of "special" patients stir up irrational feelings in their caregivers. Sick celebrities threaten to focus public scrutiny on the private world of medical caregivers. VIPs generate awe in caregivers, with loss of the objectivity essential to the practice of scientific medicine. Potentates unearth narcissism in the caregiver-patient relationship, which triggers a struggle between power and shame. Pride, privacy, and the staff's need to be in control are all threatened by introduction of the special patient into medicine's closed culture. CONCLUSION: The privacy that is owed to sick celebrities should be extended to protect overexposed staff. The awe and loss of medical objectivity that VIPs generate are counteracted by team leadership dedicated to avoiding any deviation from standard clinical procedure. Moreover, the collective ill will surrounding potentates can be neutralized by reassuring them that they are "special"-and by caregivers mending their own vulnerable self-esteem.

    Maurer, R.J.


    An aerial radiological survey of the Ames Laboratory and surrounding area in Ames, Iowa, was conducted during the period July 15--25, 1991. The purpose of the survey was to measure and document the terrestrial radiological environment at the Ames Laboratory and the surrounding area for use in effective environmental management and emergency response planning. The aerial survey was flown at an altitude of 200 feet (61 meters) along a series of parallel lines 350 feet (107 meters) apart. The survey encompassed an area of 36 square miles (93 square kilometers) and included the city of Ames, Iowa, and the Iowa State University. The results are reported as exposure rates at 1 meter above ground level (inferred from the aerial data) in the form of a gamma radiation contour map. Typical background exposure rates were found to vary from 7 to 9 microroentgens per hour (μR/h). No anomalous radiation levels were detected at the Ames Laboratory. However, one anomalous radiation source was detected at an industrial storage yard in the city of Ames. In support of the aerial survey, ground-based exposure rate and soil sample measurements were obtained at several sites within the survey perimeter. The results of the aerial and ground-based measurements were found to agree within the expected uncertainty of ±15%

  11. When celebrations go wrong: a case series of injuries after celebrating in sports. (United States)

    Momaya, Amit; Read, Connor; Estes, Reed


    Athletes often engage in various celebration maneuvers during sports events. These celebrations can result in acute injuries. Our objective was to document publicized injuries in collegiate and professional athletes resulting from celebrations and examine associated variables. A retrospective case series study was performed based on internet searches performed using the following major sporting news websites:,,,,,,, and and PubMed. Keywords used during these searches included "celebration injury", "score celebration", and "surgery after celebration". These same sources were used to document the sport, athlete's age at time of injury, celebration action, type of injury, previous play, and whether surgery was required. A total of 62 athletes sustained 62 injuries resulting from various types of celebrations. All but two athletes were males, and the average age was 26.5 years old. The injuries occurred between 1993 and 2015. Sixteen (25.8%) of these injuries required surgery. Professional soccer players accounted for the greatest number of these injuries with a total of 22 injuries. One celebration in a professional soccer player resulted in a cervical spinal cord injury and subsequent death. Common celebration maneuvers included leaping into the air, pile ups, sliding, and somersaults. Serious injuries occur in a diversity of sports after celebrations. The most prevalent celebration maneuvers resulting in injuries included sliding and pile ups. The most common injuries were ACL ruptures and ankle sprains. The most serious injuries were a spinal cord injury and ankle fractures. Sixteen (25.8%) of the injuries required surgery. By encouraging athletes to temper excessive celebrations and prohibiting certain types of celebrations, many injuries may be prevented.

  15. Antarctica Day: An International Celebration (United States)

    Pope, A.; Hambrook Berkman, J.; Berkman, P. A.


    For more than half a century, the 1959 Antarctic Treaty continues to shine as a rare beacon of international cooperation. To celebrate this milestone of peace in our civilization with hope and inspiration for future generations, Antarctica Day is celebrated each year on December 1st , the anniversary of the Antarctic Treaty signing. As an annual event - initiated by the Foundation for the Good Governance of International Spaces ( in collaboration with the Association of Polar Early Carer Scientists ( - Antarctica Day encourages participation from around the world. The Antarctic Treaty set aside 10% of the earth, 'forever to be used exclusively for peaceful purposes in the interest of mankind.' It was the first nuclear arms agreement and the first institution to govern all human activities in an international region beyond sovereign jurisdictions. In this spirit, Antarctica Day aims to: - Demonstrate how diverse nations can work together peacefully, using science as a global language of cooperation for decision making beyond national boundaries, - Provide strategies for students learning about Antarctica through art, science and history at all school levels, - Increase collaboration and communication between classrooms, communities, researchers and government officials around the world, and - Provide a focus for polar educators to build on each year. Through close collaboration with a number of partners. Antarctica Day activities have included: a Polar Film Festival convened by The Explorers Club; live sessions connecting classrooms with scientists in Antarctica thanks to PolarTREC and ARCUS; an international activity that involved children from 13 countries who created over 600 flags which exemplify Antarctica Day (these were actually flown in Antarctica with signed certificates then returned to the classes); a map where Antarctica Day participants all over the world could share what they were doing; an Antarctic bird count

    Whether deviations in the angulation discrepancy between the intercanine and interpupillary line significantly affect attractiveness is unknown. The purpose of this prospective study was to quantify dental and facial esthetics to determine whether smile angulation discrepancies in individuals identified as having attractive smiles are smaller than those in the average population. An Internet search for "best smile" and "celebrity" identified 108 celebrities (Test group). Photographs showing smiles within 10 degrees of a frontal view were gathered. In mannequin testing, small head rotation (line was measured using computer software. Groups were compared using the Mann-Whitney U test (α=.05). Usable photographs were obtained for 94 celebrities (62 women, 32 men) and were compared with photographs of 97 dental students (54 women, 43 men). Significant (P.05). Celebrities identified as having "best smile" had significantly smaller mean angulation discrepancies than the control group.

  2. The Face Management Challenges of Sport Celebrity

    Directory of Open Access Journals (Sweden)

    Diana-Luiza DUMITRIU


    Full Text Available While gaining centrality within the sport field, media accelerated its commodification process and facilitated sport actors becoming competitive on the celebrity market. The aim of this paper is to discuss the reconfiguration that the celebrity logic brought in terms of the mere condition of the sport actor and the face management challenges and remedial strategies that he has to cope with. I will thus focus on two main dimensions that I find to be constitutive for the celebrity status: one related to the augmented media exposure that sport stars are subject to and to the corollary symbolic reconfiguration of the boundaries between his public and his private life, and the second one related to the vulnerability that comes along with the new visibility of the complex repertoire of identities and social roles performed by the sport actors. Within this last dimension of the sport-related celebrity cycle of promotion, I will lay stress not only on the face threatening aspects for the sport stars, but also on the vulnerability transfer within the affinal branding network and the challenges it could bring for the brands that chose to associate their image with a sport celebrity. Thus, I argue that the kaleidoscopic public figures of sport celebrities requires high impression management involvement on their part, as well as more caution on the marketeers part.

  3. Celebrating indigenous communities compassionate traditions. (United States)

    Prince, Holly


    Living in a compassionate community is not a new practice in First Nations communities; they have always recognized dying as a social experience. First Nations hold extensive traditional knowledge and have community-based practices to support the personal, familial, and community experiences surrounding end-of-life. However, western health systems were imposed and typically did not support these social and cultural practices at end of life. In fact, the different expectations of western medicine and the community related to end of life care has created stress and misunderstanding for both. One solution is for First Nations communities to develop palliative care programs so that people can receive care at home amongst their family, community and culture. Our research project "Improving End-of-Life Care in First Nations Communities" (EOLFN) was funded by the Canadian Institutes of Health Research [2010-2015] and was conducted in partnership with four First Nations communities in Canada (see Results included a community capacity development approach to support Indigenous models of care at end-of-life. The workshop will describe the community capacity development process used to develop palliative care programs in First Nations communities. It will highlight the foundation to this approach, namely, grounding the program in community values and principles, rooted in individual, family, community and culture. Two First Nations communities will share stories about their experiences developing their own palliative care programs, which celebrated cultural capacity in their communities while enhancing medical palliative care services in a way that respected and integrated with their community cultural practices. This workshop shares the experiences of two First Nations communities who developed palliative care programs by building upon community culture, values and principles.

    De Backer, Charlotte J S; Nelissen, Mark; Vyncke, Patrick; Braeckman, Johan; McAndrew, Francis T


    In this paper we present two compatible hypotheses to explain interest in celebrity gossip. The Learning Hypothesis explains interest in celebrity gossip as a by-product of an evolved mechanism useful for acquiring fitness-relevant survival information. The Parasocial Hypothesis sees celebrity gossip as a diversion of this mechanism, which leads individuals to misperceive celebrities as people who are part of their social network. Using two preliminary studies, we tested our predictions. In a survey with 838 respondents and in-depth interviews with 103 individuals, we investigated how interest in celebrity gossip was related to several dimensions of the participants' social lives. In support of the Learning Hypothesis, age proved to be a strong predictor of interest in celebrities. In partial support of the Parasocial Hypothesis, media exposure, but not social isolation, was a strong predictor of interest in celebrities. The preliminary results support both theories, indicate that across our life span celebrities move from being teachers to being friends, and open up a list of future research opportunities.

  7. Radiological survey support activities for the decommissioning of the Ames Laboratory Research Reactor Facility, Ames, Iowa

    Energy Technology Data Exchange (ETDEWEB)

    Wynveen, R.A.; Smith, W.H.; Sholeen, C.M.; Justus, A.L.; Flynn, K.F.


    At the request of the Engineering Support Division of the US Department of Energy-Chicago Operations Office and in accordance with the programmatic overview/certification responsibilities of the Department of Energy Environmental and Safety Engineering Division, the Argonne National Laboratory Radiological Survey Group conducted a series of radiological measurements and tests at the Ames Laboratory Research Reactor located in Ames, Iowa. These measurements and tests were conducted during 1980 and 1981 while the reactor building was being decontaminated and decommissioned for the purpose of returning the building to general use. The results of these evaluations are included in this report. Although the surface contamination within the reactor building could presumably be reduced to negligible levels, the potential for airborne contamination from tritiated water vapor remains. This vapor emmanates from contamination within the concrete of the building and should be monitored until such time as it is reduced to background levels. 2 references, 8 figures, 6 tables.

While celebrity endorsement may be a good way to overcome weaknesses, such as liability of...

  13. Celebrity Politics: Correlates of Voting for Celebrities in Philippine Presidential Elections

    Directory of Open Access Journals (Sweden)

    Clarissa C. David


    Full Text Available It is common in the Philippines for celebrities in entertainment, news, and sports to run for public office and win, even with little experience in political life and limited education. The preponderance of celebrities in politics is often identif ied in the public discourse as a problem with important implications on national policy. This paper examines empirical correlates of voter preference for celebrity Presidential candidates with data from a nationally-representative survey. It finds support for the hypotheses that the likelihood of voting for celebrity candidates for President and Vice President is associated with education, television exposure, and residence in the capital city. The findings are discussed in the context of political knowledge and its role in shaping voter preferences.

  14. Materialities of Law: Celebrity Production and the Public Domain

    Directory of Open Access Journals (Sweden)

    Esther Milne


    Full Text Available Celebrity production and consumption are powerful socio-economic forces. The celebrity functions as a significant economic resource for the commercial sector and plays a fundamental symbolic role within culture by providing a shared ‘vocabulary’ through which to understand contemporary social relations. A pivotal element of this allure is the process by which the celebrity figure is able to forge an intimate link with its audience, often producing public expressions of profound compassion, respect or revulsion. This process, however, is complicated by emerging participatory media forms whose impact is experienced as new conditions of possibility for celebrity production and consumption. As Marshall argues, video mash-ups of celebrity interviews, such as those of Christian Bale or Tom Cruise, are dramatically changing the relation between celebrity and audience (Marshall, 2006: 640. Meanings produced by these audience remixes challenge the extent to which a celebrity might control her image. So is the celebrity personality, therefore, a public or private commodity? Who owns the celebrity image within remix culture? Although the celebrity figure has been thoroughly researched in relation to its patterns of consumption; semiotic power; and industry construction; less attention has been focused on the forms of celebrity governance enabled by legislative and case law settings. How might the law deal with the significant economic and cultural power exercised within celebrity culture?

  17. Ames life science telescience testbed evaluation (United States)

    Haines, Richard F.; Johnson, Vicki; Vogelsong, Kristofer H.; Froloff, Walt


    Eight surrogate spaceflight mission specialists participated in a real-time evaluation of remote coaching using the Ames Life Science Telescience Testbed facility. This facility consisted of three remotely located nodes: (1) a prototype Space Station glovebox; (2) a ground control station; and (3) a principal investigator's (PI) work area. The major objective of this project was to evaluate the effectiveness of telescience techniques and hardware to support three realistic remote coaching science procedures: plant seed germinator charging, plant sample acquisition and preservation, and remote plant observation with ground coaching. Each scenario was performed by a subject acting as flight mission specialist, interacting with a payload operations manager and a principal investigator expert. All three groups were physically isolated from each other yet linked by duplex audio and color video communication channels and networked computer workstations. Workload ratings were made by the flight and ground crewpersons immediately after completing their assigned tasks. Time to complete each scientific procedural step was recorded automatically. Two expert observers also made performance ratings and various error assessments. The results are presented and discussed.

  5. Intimate Relationships and Attitudes Toward Celebrities

    Directory of Open Access Journals (Sweden)

    Lynn E. McCutcheon


    Full Text Available Previous research indicates that persons who self-report a high level of preoccupation with celebrities tend to have lower levels of well-being. We administered the “Romantic Partner Conflict Scale”, the “Love Attitudes Scale”, the soulmate subscale from the “Relationship Theories Questionnaire”, and the anxiety subscale from the “Experiences in Close Relationships Scale” to 330 students from four universities to see how well scores on these measures would predict scores on each of the three subscales from the “Celebrity Attitude Scale” (CAS. We predicted that persons whose scores on these measures of intimate relationships indicated a troubled, anxious, or poor quality relationship would have higher scores on the CAS, especially on its two problematic subscales. In three multiple regressions, specific measures of behavior during conflict with a romantic partner and certain love styles significantly predicted scores on all three of the CAS subscales. We discuss the implications of being a celebrity worshiper on one’s relationship with an intimate partner.

  6. Antecedents of Taiwanese adolescents' purchase intention toward the merchandise of a celebrity: the moderating effect of celebrity adoration. (United States)

    Chiou, Jyh-Shen; Huang, Chien-Yi; Chuang, Min-Chieh


    The purpose of the present study was to investigate the relative importance of adolescents' attitude toward an act (the degree to which the person had a favorable or unfavorable evaluation or appraisal of the act's behavior in question), perceived norm, and perceived behavioral control in predicting Taiwanese adolescents' intention to purchase the merchandise of a celebrity when they had different levels of celebrity adoration. The present results showed that the relative strengths of attitude toward the act and the perception of behavioral control in predicting purchase intention toward the merchandise of a celebrity were stronger for adolescents in the celebrity adoration group than for adolescents in the celebrity nonadoration group. On the other hand, the relative importance of the perceived norm in predicting the attitude toward the act and the purchase intention was stronger for adolescents in the celebrity nonadoration group than for adolescents in the celebrity adoration group.

  7. A theoretical reflection of celebrity endorsement in Nigeria

    Directory of Open Access Journals (Sweden)

    Milford I Udo


    Full Text Available The use of celebrities such as movie stars, sports heroes, entertainers, music experts and all the likes as endorsers by marketers in promoting brand awareness, recognition, and preferences, has become the order of the day in advertising practices both in developed and developing economies. It therefore behooves on marketing professionals to design possible techniques to enhance its effective use by companies. This instigated the researchers to theoretically examine what celebrity endorsement is all about, celebrity-worship relationship and endorser effects, risks associated with the use of celebrity endorsement and celebrity endorsement selection criteria. A critical review of extant literature revealed that celebrity endorsement makes advertisement more memorable and the company in the short-run generates high brand awareness as well as an increase in market share. There are certain risks associated with celebrity endorsement such as negative publicity, overshadowing, multiple endorsement, over-endorsement, extinction and cost implications. The study indicated that, successful celebrity endorsement is a combination of attributes such as trustworthiness, expertise, similarity, familiarity, likeability, and a match between the celebrity and the message (brand,. To ensure the effective use of celebrity endorsement, the paper highlighted some strategic options.

  14. Copycat Suicide Induced by Entertainment Celebrity Suicides in South Korea (United States)

    Jang, Soo Ah; Sung, Ji Min; Park, Jin Young


    Objective Throughout the past several years, there have been a number of entertainment celebrity suicides in South Korea. The aim of this study was to investigate the clustering of suicides following celebrities' suicides in South Korea from 2005 to 2008, particularly according to certain characteristics. Methods Seven celebrity suicides were examined and defined using the Korean Integrated Newspaper Database System (KINDS) and from these, we considered four affected periods occurring 28 days after each celebrity's suicide. A Poisson time-series autoregression model was used to estimate the relative risk of the total suicide number for each affected period from 2005 to 2008. Logistic regression analysis was performed to investigate whether there were specific increases in the numbers of suicides in subgroups matching each celebrity. Results There were significant increases in the risk of suicide during the affected periods. Remarkable increases were found in the subgroups matching each celebrity, especially in the group in which all factors (sex, age, and method) were similar. Conclusion This study provides confirmation that a significant copycat effect was induced by these celebrities' suicides, especially among people who identified more with the celebrities. This implies that countermeasures for upright media coverage of celebrity suicides should be discussed and practiced properly in South Korea. PMID:26766949

  16. Functionally enhanced brown adipose tissue in Ames dwarf mice. (United States)

    Darcy, Justin; Bartke, Andrzej


    Reduced insulin-like growth factor 1/insulin signaling (IIS) has been linked to extended longevity in species ranging from yeast to mammals. In mammals, this is exemplified in Ames dwarf (Prop1 df/df ) mice, which have a 40%-60% increase in longevity (males and females, respectively) due to their recessive Prop1 loss-of-function mutation that results in lack of growth hormone (GH), thyroid-stimulating hormone and prolactin. Our laboratory has previously shown that Ames dwarf mice have functionally unique white adipose tissue (WAT) that improves, rather than impairs, insulin sensitivity. Because GH and thyroid hormone are integral to adipose tissue development and function, we hypothesized that brown adipose tissue (BAT) in Ames dwarf mice may also be functionally unique and/or enhanced. Here, we elaborate on our recent findings, which demonstrate that BAT is functionally enhanced in Ames dwarf mice, and suggest that BAT removal in these mice results in utilization of WAT depots as an energy source. We also discuss how our findings compare to those in other long-lived dwarf mice with altered IIS, which unlike Ames dwarf mice, are essentially euthyroid. Lastly, we provide some insights into the implications of these findings and discuss some of the necessary future work in this area.

  17. Celebrity chefs put their left cheek forward: Cover image orientation in celebrity cookbooks. (United States)

    Lindell, Annukka K


    Portrait pose orientations influence perception: the left cheek is more emotionally expressive; females' right cheeks appear more attractive. Posing biases are established in paintings, photographs, and advertisements, however, book covers have not previously been examined. This paper assesses cover image orientation in a book genre that frequently features a cover portrait: the celebrity cookbook. If marketers intuitively choose to enhance chefs' emotional expressivity, left cheek poses should predominate; if attractiveness is more important, right cheek poses will be more frequent for females, with a left or no cheek bias for males. Celebrity cookbook covers (N = 493) were sourced online; identity, portrait orientation, photo type, and sex were coded. For celebrity cookbooks, left cheek covers (39.6%) were more frequent than right cheek (31.6%) or midline covers (28.8%); sex did not predict pose orientation. An interaction between photo type and sex bordered on significance: photo type did not influence females' pose orientation; for males, the left cheek bias present for head and torso images was absent for full body and head only photos. Overall, the left cheek bias for celebrity cookbook covers implies that marketers intuitively select images that make the chefs appear happier and/or more emotionally expressive, enhancing engagement with the audience.

  8. The celebrity appeal questionnaire: sex, entertainment, or leadership. (United States)

    Stever, Gayle S


    The Celebrity Appeal Questionnaire was constructed to operationalize constructs related to why fans are attracted to their favorite celebrities and was developed for use with fan bases for specific celebrities. This revised version asked fans of a specific celebrity to rank order three roles they might see the target celebrity playing in society with an option to not rank them at all. Of 409 respondents attending Josh Groban fan club meetings, 75% said Groban's most important role in society was as a leader and role model in trying to make the world a better place. A factor analysis of correlations of Likert-type scale ratings and an analysis relating those factors back to the rank orderings support the internal reliability and validity of the questionnaire.

  12. The Cosmic Mandala: Celebrating Tibetan Cosmologies (United States)

    Larsen, Kristine


    The past decade has seen an increased establishment of Tibetan cultural centers in North America and increased public interest in and media coverage of Tibetan culture. As a result, interest has grown in all aspects of this rich tradition. Astronomy has long played an important role in the lives of the Tibetan people, from their unique luni-solar calendar to their tradition of combining what they call "astro-science" and medicine. To this day, nomads in northern Tibet will ask the North Star - the "Stable Star of the North" - to protect a wayward animal for the night in the expectation that the star will aid in the animal's return in the morning. In Tibetan cosmology, our universe is symbolized as a series of parallel disks centered around Mount Meru, with the heavenly bodies orbiting around it. Central to this cosmology is the concept that time and space have no absolute beginning or end (paralleling the concept of eternal human reincarnation), but that at any given time there exist a billionfold impermanent universes, each one involved in its own independent 4-stage cycle of emptiness, becoming, unfolding, and dissolution. Two distinct symbolic cosmology systems, the Abhidharma ("Topics of special knowledge") and Kalachakra ("Wheel of time"), are recognized in Tibetan culture. These cosmologies also differ in their geographical description of Mount Meru and the "continents" as well as the specifics of the 4-stage cosmological cycle. This poster will celebrate the richness of Tibetan "astro-science", including the calendar, star names, traditional cosmological systems, and astronomical artwork, and demonstrate ways that this tradition can be directly utilized to celebrate and teach cultural cosmologies during the IYA.

  16. Celebrity endorsed music videos: innovation to foster youth health promotion. (United States)

    Macnab, A J; Mukisa, R


    There are calls for innovation in health promotion and for current issues to be presented in new and exciting ways; in addition to creating engaging messages, novel ways to deliver health messaging are needed, especially where youth are the key target audience. When pupils in WHO Health Promoting Schools were asked what health messages would resonate with them, they also identified celebrities as the 'messengers' they would be particularly likely to listen to. Expanding on these discussions, the pupils quoted celebrity-recorded music videos containing health and lifestyle messaging as an example of where they had learned from celebrities. Their ability to sing phrases from the songs and repeat key health messages they contained indicated the videos had commanded attention and provided knowledge and perspectives that had been retained. We located on YouTube the video titles the pupils identified and evaluated the content, messaging and production concepts these celebrity-recorded music videos incorporated. All are good examples of the health promotion genre known as education entertainment, where educational content is intentionally included in professionally produced entertainment media to impart knowledge, create favorable attitudes and impact future behaviors. The importance of this genre is growing in parallel with the burgeoning influence of social media. Music videos resonate with youth, and celebrity recordings combine young people's love of music with their fascination for the aura of celebrity. Hence, producing videos that combine an effective health message with celebrity endorsement offers potential as an innovative conduit for health promotion messaging among youth.

  17. Drug-related celebrity deaths: A cross-sectional study. (United States)

    Just, Johannes M; Bleckwenn, Markus; Schnakenberg, Rieke; Skatulla, Philipp; Weckbecker, Klaus


    Celebrities are at risk for premature mortality as well as drug-related death. Despite being a vulnerable patient group, celebrities influence people's health behaviours through biological, psychological and social processes. Therefore, celebrity endorsement of the topic could be one way to challenge the current "opioid endemic". Our aim was to better understand the factors surrounding drug-related celebrity deaths by investigating the incidence as well as substances used between 1970 and 2015 using a cross-sectional study design. We searched public databases for drug-related celebrity deaths between 1970 and 2015. They were categorized for sex, profession, age at death, year of death and substances involved. The main outcome measures are descriptive values including number of drug deaths per year and substances involved. Secondary outcome measures are analytical questions to examine whether and which factors influence age at death and year of death (e.g. type of substance use disorder). We identified 220 celebrities who died a drug-related death with a clear indication of involved substances between 1970 and 2015. The average age at death was 38.6 years; 75% were male. Most celebrities died between the age of 25 and 40. The number of drug-related deaths increased in the 21st century, with a significant increase in the use of prescription opioids. Deaths involving prescription opioids and heroin were associated with a significantly lower mean age at death compared to deaths where these substances were not involved. Compared to the 20th century, the total number of celebrities who died from a drug-related death in the 21st century increased, possibly due to an increased involvement of prescription opioids. Negative effects on individual health decisions of celebrity's followers could be the result.

  18. Popular Music Celebrity Endorsements in Food and Nonalcoholic Beverage Marketing. (United States)

    Bragg, Marie A; Miller, Alysa N; Elizee, Juleen; Dighe, Shatabdi; Elbel, Brian D


    Food and beverage marketing has been associated with childhood obesity. We quantified the number and type of food or beverage brands promoted by music celebrities, assessed the nutritional quality of the products, and examined Teen Choice Award data to assess the celebrities' popularity among adolescents. This was a descriptive study. A list of music celebrities associated with the 2013 and 2014 Billboard Hot 100 Chart, which ranks songs according to sales and radio impressions, was compiled. Data on celebrity endorsements were gathered from official company Web sites, YouTube commercials, an advertising database, and media reports. Nutritional quality of foods was assessed according to the Nutrient Profile Index, whereas nonalcoholic beverages were evaluated based on calories from added sugar. Teen Choice Award nominations were used to measure the celebrities' popularity among adolescents. Of the 590 endorsements made by the 163 celebrities in the sample, consumer goods (eg, fragrances, makeup) represented the largest endorsement category (26%), followed by food and beverage (18%) and retail (11%). Sixty-five celebrities were collectively associated with 57 different food and beverage brands owned by 38 parent companies. Of these 65 celebrities, 53 (81.5%) had ≥1 Teen Choice Award nomination. Forty-nine (71%) of the 69 nonalcoholic beverage references promoted sugar-sweetened beverages. Twenty-one (80.8%) of the 26 endorsed foods were energy dense and nutrient poor. Baauer,, Justin Timberlake, Maroon 5, and Britney Spears had the most food and beverage endorsements. This study demonstrates that music celebrities who are popular among adolescents endorse energy-dense, nutrient-poor products. Copyright © 2016 by the American Academy of Pediatrics.

  20. 1998 NASA-ASEE-Stanford Summer Faculty Fellowship Program (United States)


    This report presents the essential features and highlights of the 1998 Summer Faculty Fellowship Program at Ames Research Center and Dryden Flight Research Center in a comprehensive and concise form. Summary reports describing the fellows' technical accomplishments are enclosed in the attached technical report. The proposal for the 1999 NASA-ASEE-Stanford Summer Faculty Fellowship Program is being submitted under separate cover. Of the 31 participating fellows, 27 were at Ames and 4 were at Dryden. The Program's central feature is the active participation by each fellow in one of the key technical activities currently under way at either the NASA Ames Research Center or the NASA Dryden Flight Research Center. The research topic is carefully chosen in advance to satisfy the criteria of: (1) importance to NASA, (2) high technical level, and (3) a good match to the interests, ability, and experience of the fellow, with the implied possibility of NASA-supported follow-on work at the fellow's home institution. Other features of the Summer Faculty Fellowship Program include participation by the fellows in workshops and seminars at Stanford, the Ames Research Center, and other off-site locations. These enrichment programs take place either directly or remotely, via the Stanford Center for Professional Development, and also involve specific interactions between fellows and Stanford faculty on technical and other academic subjects. A few, brief remarks are in order to summarize the fellows' opinions of the summer program. It is noteworthy that 90% of the fellows gave the NASA-Ames/Dryden- Stanford program an "excellent" rating and the remaining 10%, "good." Also, 100% would recommend the program to their colleagues as an effective means of furthering their professional development as teachers and researchers. Last, but not least, 87% of the fellows stated that a continuing research relationship with their NASA colleagues' organization probably would be maintained. Therefore

  2. NASA logo painted on orbiter Endeavour (United States)


    A KSC worker paints the NASA logo on the port wing of the orbiter Endeavour, which is scheduled to launch in December for STS-88. The paint is a special pigment that takes 18 hours to dry; the whole process takes approximately two weeks to complete. The NASA logo, termed 'meatball,' was originally designed in the late 1950s. It symbolized NASA's role in aeronautics and space in the early years of the agency. The original design included a white border surrounding it. The border was dropped for the Apollo 7 mission in October 1968, replaced with royal blue to match the background of the emblem. In 1972 the logo was replaced by a simple and contemporary design -- the 'worm' -- which was retired from use last year. NASA reverted to its original logo in celebration of the agency's 40th anniversary in October, and the 'golden age' of America's space program. All the orbiters will bear the new logo.

  3. NASA Ames Summer High School Apprenticeship Research Program: 1986 research papers (United States)

    Powell, Patricia


    Engineering enrollments are rising in universities; however the graduate engineering shortage continues. Particularly, women and minorities will be underrepresented for many years. As one means of solving this shortage, Federal agencies facing future scientific and technological challenges were asked to participate in the Summer High School Apprenticeship Research Program (SHARP). This program was created to provide an engineering experience for gifted female and minority high school students at an age when they could still make career and education decisions. The SHARP program is designed for high school juniors who are U.S. citizens, are 16 years old, and who have very high promise in math and science through outstanding academic performance in high school. Students who are accepted into this summer program will earn as they learn by working 8 hr days in a 5-day work week. Reports from SHARP students are presented.

    Powell, P.


    Engineering enrollments are rising in universities; however, the graduate engineer shortage continues. Particularly, women and minorities will be underrepresented for years to come. As one means of solving this shortage, Federal agencies facing future scientific and technological challenges were asked to participate in the Summer High School Apprenticeship Research Program (SHARP). This program was created 4 years ago to provide an engineering experience for gifted female and minority high school students at an age when they could still make career and education decisions. The SHARP Program is designed for high school juniors (women and minorities) who are U.S. citizens, are 16 years old, and who have unusually high promise in mathematics and science through outstanding academic performance in high school. Students who are accepted into this summer program will earn as they learn by working 8 hours a day in a 5-day work week. This work-study program features weekly field trips, lectures and written reports, and job experience related to the student's career interests.

  6. Developing questionnaires for educational research: AMEE Guide No. 87 (United States)

    La Rochelle, Jeffrey S.; Dezee, Kent J.; Gehlbach, Hunter


    In this AMEE Guide, we consider the design and development of self-administered surveys, commonly called questionnaires. Questionnaires are widely employed in medical education research. Unfortunately, the processes used to develop such questionnaires vary in quality and lack consistent, rigorous standards. Consequently, the quality of the questionnaires used in medical education research is highly variable. To address this problem, this AMEE Guide presents a systematic, seven-step process for designing high-quality questionnaires, with particular emphasis on developing survey scales. These seven steps do not address all aspects of survey design, nor do they represent the only way to develop a high-quality questionnaire. Instead, these steps synthesize multiple survey design techniques and organize them into a cohesive process for questionnaire developers of all levels. Addressing each of these steps systematically will improve the probabilities that survey designers will accurately measure what they intend to measure. PMID:24661014

    CERN Multimedia


    "(…) An information paper intended to help every staff member to feel at home in the Organization and to maintain the ideal of European co-operation and the team spirit which are essential to the achievement of our final aim: scientific research on an international scale." This quote is taken from the preface of the first issue of the CERN Courier, published in August 1959. "In 50 years, the CERN Courier has changed a lot. It has broadened its scope to become an international magazine on high-energy physics and its readership has grown from a few thousand internal readers to more than 25 000 readers across the world", says Christine Sutton, the present editor of the magazine. The CERN Courier is commemorating its anniversary with a special July/August issue celebrating the past 50 years. "We’ve reproduced the original edition in its entirety", explains Sutton. "It’s amazing to me how much the first editor, Roger Anthoine, achieved in jus...

  8. Celebrating the first of a kind

    CERN Multimedia


    It was on 7 and 8 October 1954 that the first meeting of the CERN Council took place, opened by Frenchman Robert Valeur, retiring Chairman of the interim Council that had overseen the establishment of CERN. On the day we celebrate that first meeting with a special Council Symposium, it’s interesting to look back at the meeting’s minutes.    Penned in the dry official language that is the hallmark of such documents, the momentous nature of what had been achieved nevertheless shines through. “The retiring Chairman stressed the importance of the creation of the Organization which would be the first scientific organization of its kind in the world,” Valeur was reported as saying, before going on to introduce such luminaries as Swiss writer and federalist, Denis de Rougemont, and American Nobel Prize winner, Isidor Rabi, both of whom had played instrumental roles in the creation of CERN. CERN pioneer Pierre Auger would only be present the following ...

  9. Neural predictors of evaluative attitudes toward celebrities. (United States)

    Izuma, Keise; Shibata, Kazuhisa; Matsumoto, Kenji; Adolphs, Ralph


    Our attitudes toward others influence a wide range of everyday behaviors and have been the most extensively studied concept in the history of social psychology. Yet they remain difficult to measure reliably and objectively, since both explicit and implicit measures are typically confounded by other psychological processes. We here address the feasibility of decoding incidental attitudes based on brain activations. Participants were presented with pictures of members of a Japanese idol group inside an functional magnetic resonance imaging scanner while performing an unrelated detection task, and subsequently (outside the scanner) performed an incentive-compatible choice task that revealed their attitude toward each celebrity. We used a real-world election scheme that exists for this idol group, which confirmed both strongly negative and strongly positive attitudes toward specific individuals. Whole-brain multivariate analyses (searchlight-based support vector regression) showed that activation patterns in the anterior striatum predicted each participant's revealed attitudes (choice behavior) using leave-one-out (as well as 4-fold) cross-validation across participants. In contrast, attitude extremity (unsigned magnitude) could be decoded from a distinct region in the posterior striatum. The findings demonstrate dissociable striatal representations of valenced attitude and attitude extremity and constitute a first step toward an objective and process-pure neural measure of attitudes. © The Author (2016).

  10. Students Across Texas Celebrate Astronomy Day (United States)

    Preston, S.; Wetzel, M.; Hemenway, M. K.


    Over the past three years, McDonald Observatory has offered special Astronomy Day videoconference programs to students across Texas—the second largest state in the U.S. (Only Alaska is larger). Videoconferencing allows many students and teachers access to our Observatory, which is remotely located 180 miles (290 kilometers) from any major city. McDonald Observatory partners with Connect2Texas to advertise the Astronomy Day event. Connect2Texas provides the electronic bridge between schools and the Observatory. They also provide an online evaluation for teachers to complete. In 2009 the Astronomy Day videoconference celebrated the International Year of Astronomy and the historic observations made by Galileo Galilei. During the videoconference, the classes explore the Moon or Venus by making real-time telescopic observations. Students also receive an introduction to the Observatory, an opportunity to perform an activity relating to Galileo's observations, and an interview with an astronomer. A website provides teachers pre-and post-video conference materials, instructions, and a certificate of completion that can be customized for each student. The website also lists content alignment with state science education standards.

  15. Ames Laboratory annual site environmental report, calendar year 1996

    International Nuclear Information System (INIS)


    This report summarizes the environmental status of Ames Laboratory for calendar year 1996. It includes descriptions of the Laboratory site, its mission, the status of its compliance with applicable environmental regulations, its planning and activities to maintain compliance, and a comprehensive review of its environmental protection, surveillance and monitoring programs. Ames Laboratory is located on the campus of Iowa State University (ISU) and occupies twelve buildings owned by the Department of Energy (DOE). The Laboratory also leases space in ISU owned buildings. Laboratory activities involve less than ten percent of the total chemical use and approximately one percent of the radioisotope use on the ISU campus. In 1996, the Office of Assurance and Assessment merged with the Environment, Safety and Health Group forming the Environment, Safety, Health and Assurance (ESH and A) office. In 1996, the Laboratory accumulated and disposed of wastes under US Environmental Protection Agency (EPA) issued generator numbers. Ames Laboratory submitted a Proposed Site Treatment Plan to EPA in December 1995. This plan complied with the Federal Facilities Compliance Act (FFCA). It was approved by EPA in January 1996. The consent agreement/consent order was issued in February 1996. Pollution awareness, waste minimization and recycling programs, implemented in 1990 and updated in 1994, continued through 1996. Included in these efforts were a waste white paper and green computer paper recycling program. Ames Laboratory also continued to recycle salvageable metal and used oil, and it recovered freon for recycling. All of the chemical and nearly all of the radiological legacy wastes were properly disposed by the end of 1996. Additional radiological legacy waste will be properly disposed during 1997

  16. Ames Laboratory Site Environmental Report, Calendar year 1991

    International Nuclear Information System (INIS)

    Mathison, L.


    The summarized data and conclusions from the Ames Laboratory environmental monitoring program are presented in this Annual Site Environmental Report. This program is a working requirement of Department of Energy (DOE) Order 5484.1, ''Environmental Protection, Safety, and Health Protection Information Reporting Requirements'' and Order 5400.1, ''General Environmental Protection Program.'' Ames Laboratory is located on the campus of Iowa State University (ISU) and occupies several buildings owned by the DOE. The Laboratory also leases space in ISU-owned buildings. Laboratory research activities involve less than ten percent of the total chemical use and one percent of the radioisotope use on the ISU campus. Ames Laboratory is responsible for a small chemical burial site, located on ISU property. The site was used for the disposal of chemical and metal slags from thorium and uranium production. Samples of water from existing test wells and upstream and downstream sites on the nearby Squaw Creek show no detectable migration of the contents of the burial site. A Site Assessment plan submitted to the State of Iowa Department of Natural Resources (DNR) was approved. A Remedial Investigation/Feasibility Study work plan has been completed for additional studies at the site. This has been reviewed and approved by the DOE Chicago Field Office and the DNR. A National Environmental Policy Act (NEPA) review of the site resulted in a categorical exclusion finding which has been approved by the DOE. Ames Laboratory has an area contaminated by diesel fuel at the location of a storage tank which was removed in 1970. Soil corings and groundwater have been analyzed for contamination and an assessment written. Pollution awareness and waste minimization programs and plans were implemented in 1990. Included in this effort was the implementation of a waste white paper and green computer paper recycling program

  17. Phospholipid composition and longevity: lessons from Ames dwarf mice. (United States)

    Valencak, Teresa G; Ruf, Thomas


    Membrane fatty acid (FA) composition is correlated with longevity in mammals. The "membrane pacemaker hypothesis of ageing" proposes that animals which cellular membranes contain high amounts of polyunsaturated FAs (PUFAs) have shorter life spans because their membranes are more susceptible to peroxidation and further oxidative damage. It remains to be shown, however, that long-lived phenotypes such as the Ames dwarf mouse have membranes containing fewer PUFAs and thus being less prone to peroxidation, as would be predicted from the membrane pacemaker hypothesis of ageing. Here, we show that across four different tissues, i.e., muscle, heart, liver and brain as well as in liver mitochondria, Ames dwarf mice possess membrane phospholipids containing between 30 and 60 % PUFAs (depending on the tissue), which is similar to PUFA contents of their normal-sized, short-lived siblings. However, we found that that Ames dwarf mice membrane phospholipids were significantly poorer in n-3 PUFAs. While lack of a difference in PUFA contents is contradicting the membrane pacemaker hypothesis, the lower n-3 PUFAs content in the long-lived mice provides some support for the membrane pacemaker hypothesis of ageing, as n-3 PUFAs comprise those FAs being blamed most for causing oxidative damage. By comparing tissue composition between 1-, 2- and 6-month-old mice in both phenotypes, we found that membranes differed both in quantity of PUFAs and in the prevalence of certain PUFAs. In sum, membrane composition in the Ames dwarf mouse supports the concept that tissue FA composition is related to longevity.

  18. Is the Moon Illusion a Celestial Ames Demonstration? (United States)

    Brecher, Kenneth


    To most naked eye observers, the Moon appears larger when seen near the horizon than it does when seen near the zenith. This "Moon Illusion” has been reported from as early as the fourth century BC and has been the subject of hundreds of papers and two books. Its explanation does not lie in the realm of physics (atmospheric refraction) or astronomy (eccentric lunar orbit) but, rather, in the realm of visual perception. Theories for the cause of the effect abound but, at present, there is no universally accepted explanation. Because the effect can be easily observed in many locations and during the course of an academic year, the moon illusion can provide a nice astronomical example that involves both direct observations and theoretical analysis. As part of the NSF funded "Project LITE: Light Inquiry Through Experiments", we have been developing inexpensive experiments and demonstrations that can be done at home. One of these is a miniature version of the classic "Ames Room". The life size version was originally developed by Adelbert Ames, Jr. and can be seen in many science museums. Our "digital” Ames Room has been designed to be printed on heavy paper using an inexpensive inkjet printer from a PDF file that is posted on the Project LITE web site and then cut and folded to make the room. When viewed through one wall using a commonly available door viewer, it dramatically demonstrates how the eye and brain system assesses the relative size of objects by making comparisons with the surrounding environment in which the objects are placed. In this presentation we will discuss some insights that the Ames Room provides that may offer clues to the correct explanation for the Moon Illusion. Project LITE is supported by the NSF through DUE Grant # 0715975.

  19. The AMES network strategy developments within and outside the EU

    International Nuclear Information System (INIS)

    Sevini, F.; Debarberis, L.; Davies, L.M.; English, C.


    The AMES (Ageing Materials Evaluation and Studies) network started its activity in 1993 with the aim of studying the consequences and the mechanisms of the ageing process in materials used for nuclear reactor components. Together with ENIQ, NESC, EPERC, it forms the so-called ''Structural Integrity of Industrial Components'' cluster of networks operated by the Joint Research Centre - Institute for Advanced Materials of the European Commission. After two initial phases dedicated to the compilation of state-of-the-art reports on non-destructive monitoring techniques for thermal ageing, dosimetry, survey of regulatory requirements, predictive formulas for irradiation embrittlement, AMES has entered its third strategy phase with the fifth EURATOM Framework Program, Nuclear Fission Safety Key Action. Most of the projects proposed for this program and sustained by the Steering committee were selected for funding. Their focus is on the influence of chemical composition, namely phosphorus and nickel content, on the irradiation embrittlement of reactor pressure vessel materials, on the improvement of surveillance temperature measurement, on the validation of the Master Curve approach, and on ND techniques to monitor ageing of irradiated steels. The paper describes the objectives of the new fifth Framework Program projects and how they are part of the AMES strategy, pointing out the involvement of CEEC and NIS countries. (authors)

    The summarized data and conclusions from the Ames Laboratory environmental monitoring program are presented in this Annual Site Environmental Report. Pollution awareness and waste minimization programs and plans implemented in 1990 are continuing to date. Ames Laboratory (AL) is responsible for a small chemical burial site, located on ISU property. The site was used for the disposal of chemical and metal slags from thorium and uranium production. Samples of water from existing test wells, and upstream and downstream sites on the nearby Squaw Creek, have not detected migration of the buried materials off site. Surface, hand auger and deep boring soil samples have been collected from the site. The analytical results are pending, Six new monitoring wells have been installed and sampled. Analytical results are pending. Ames Laboratory is responsible for an area contaminated by diesel fuel that leaked from an underground storage tank (UST) in 1970. The tank was removed that year. Soil borings and groundwater have been analyzed for contamination and a preliminary assessment written. Nine small inactive waste sites have been identified for characterization. The NEPA review for this work resulted in a CX determination. The work plans were approved by AL and CH. A subcontractor has surveyed and sampled the sites. Analytical results are pending

  1. A theoretical reflection of celebrity endorsement in Nigeria


    Milford I Udo; Nwulu, Chinyere Stella


    The use of celebrities such as movie stars, sports heroes, entertainers, music experts and all the likes as endorsers by marketers in promoting brand awareness, recognition, and preferences, has become the order of the day in advertising practices both in developed and developing economies. It therefore behooves on marketing professionals to design possible techniques to enhance its effective use by companies. This instigated the researchers to theoretically examine what celebrity endorsement...

  3. Trends in Media Reports of Celebrities' Breast Cancer Treatment Decisions. (United States)

    Sabel, Michael S; Dal Cin, Sonya


    Although the increasing use of bilateral mastectomies is multifaceted, one source of influence may be the media, including coverage of celebrity breast cancer treatment. We examined trends in media reporting that might impact decision making among women with breast cancer. We performed searches of two comprehensive online databases for articles from major U.S. print publications mentioning celebrities and terms related to the word "breast" and terms related to cancer treatment. Automated analysis using custom-created dictionaries was used to determine word frequencies over time. An analysis of net media tone was conducted using Lexicoder Sentiment Dictionaries. Celebrity breast cancer media reports significantly increased since 2004 (p celebrity had bilateral mastectomies than unilateral mastectomy or breast conservation (44.8 vs 26.1 %, p celebrities undergoing bilateral mastectomy for cancer had no mention of genetics, family history, or risk. Media reports of celebrity breast cancer present a bias toward bilateral mastectomies in both frequency and tone. This may sway public opinion, particularly when factors such as risk and genetics are excluded. Surgeons need to work with the media to improve cancer reporting and identify methods to better educate patients prior to surgical consultations.

  4. Spatial delayed nonmatching-to-sample performances in long-living Ames dwarf mice. (United States)

    Derenne, Adam; Brown-Borg, Holly M; Martner, Sarah; Wolff, Wendy; Frerking, Morgan


    Ames dwarf mice have an extended lifespan by comparison with normal mice. Behavioral testing has revealed that sometimes Ames dwarf mice also evince superior performances relative to normal mice, but in other cases they do not. In this experiment, Ames dwarf and normal mice were compared on a T-maze test and on a delayed nonmatching-to-sample variant of a T-maze test. On the simple T-maze, Ames dwarf and normal mice committed comparable numbers of errors. On the nonmatching-to-sample task, normal mice mastered the discrimination by the end of the experiment while Ames dwarf mice did not. The apparatus, distances traveled and session duration were equivalent between the two tasks. The poorer performances of Ames dwarf mice on the nonmatching-to-sample task suggests that Ames dwarf mice may not be as capable of learning relatively cognitively complex tasks as normal mice. © 2013.

  12. Groundwater hydrology study of the Ames Chemical Disposal Site

    International Nuclear Information System (INIS)

    Stickel, T.


    The Ames Laboratory Chemical Disposal Site is located in northwestern Ames, Iowa west of Squaw Creek. From 1957 to 1966, Ames Laboratory conducted research to develop processes to separate uranium and thorium from nuclear power fuel and to separate yttrium from neutron shielding sources. The wastes from these processes, which contained both hazardous and radiological components, were placed into nine burial pits. Metal drums, plywood boxes, and steel pails were used to store the wastes. Uranium was also burned on the ground surface of the site. Monitoring wells were placed around the waste burial pits. Groundwater testing in 1993 revealed elevated levels of Uranium 234, Uranium 238, beta and alpha radiation. The north side of the burial pit had elevated levels of volatile organic compounds. Samples in the East Ravine showed no volatile organics; however, they did contain elevated levels of radionuclides. These analytical results seem to indicate that the groundwater from the burial pit is flowing down hill and causing contamination in the East Ravine. Although there are many avenues for the contamination to spread, the focus of this project is to understand the hydrogeology of the East Ravine and to determine the path of groundwater flow down the East Ravine. The groundwater flow data along with other existing information will be used to assess the threat of chemical migration down the East Ravine and eventually off-site. The primary objectives of the project were as follows: define the geology of the East Ravine; conduct slug tests to determine the hydraulic conductivity of both oxidized and unoxidized till; develop a three-dimensional mathematical model using ModIME and MODFLOW to simulate groundwater flow in the East Ravine

    The U.S. Department of Energy completed a voluntary removal action at the Ames chemical disposal site, a site associated with the early days of the Manhattan Project. It contained chemical and low-level radioactive wastes from development of the technology to extract uranium from uranium oxide. The process included the preparation of a Remedial Investigation, Feasibility Study, Baseline Risk Assessment, and, ultimately, issuance of a Record of Decision. Various stakeholder groups were involved, including members of the regulatory community, the general public, and the landowner, Iowa State University. The site was restored and returned to the landowner for unrestricted use.

  14. The Risk of Vampire Effect in Advertisements Using Celebrity Endorsement

    Directory of Open Access Journals (Sweden)

    Tetyana Kuvita


    Full Text Available In the race to get the attention of the target audience, advertisers often use special attention-getting devices. This in turn exposes them to a higher risk of creating a vampire effect when the core message about the brand or a product is “eaten up” by such devices. The concept of a vampire effect in advertising appears to be under-researched in the current literature. Therefore, this paper provides deeper insights into the vampire effect occurrences in printed advertisements using celebrity endorsement. The paper is based on a qualitative study with an eye-tracking device with 12 participants and on the following experiment with 60 university students. The research found that a significantly higher risk of creating a vampire effect exists when using an unrelated celebrity as an attention-getting device than when using a related celebrity or no celebrity at all. Marketers are advised to use related celebrities if choosing to stick to this attention-getting approach. However, the concept of “relatedness” should be pre-tested prior to launching an advertising campaign.

  15. Computational Nanoelectronics and Nanotechnology at NASA ARC (United States)

    Saini, Subhash


    Both physical and economic considerations indicate that the scaling era of CMOS will run out of steam around the year 2010. However, physical laws also indicate that it is possible to compute at a rate of a billion times present speeds with the expenditure of only one Watt of electrical power. NASA has long-term needs where ultra-small semiconductor devices are needed for critical applications: high performance, low power, compact computers for intelligent autonomous vehicles and Petaflop computing technolpgy are some key examples. To advance the design, development, and production of future generation micro- and nano-devices, IT Modeling and Simulation Group has been started at NASA Ames with a goal to develop an integrated simulation environment that addresses problems related to nanoelectronics and molecular nanotecnology. Overview of nanoelectronics and nanotechnology research activities being carried out at Ames Research Center will be presented. We will also present the vision and the research objectives of the IT Modeling and Simulation Group including the applications of nanoelectronic based devices relevant to NASA missions.

  17. Estimation of γ irradiation induced genetic damage by Ames test

    International Nuclear Information System (INIS)

    Hosoda, Eiko


    Mutation by 60 Co γ irradiation was studied in five different histidine-requiring auxotrophs of Salmonella typhimurium. The strains TA98 (sensitive to frameshift) and TA100 (sensitive to base-pair substitution) were irradiated (10-84 Gy and 45-317 Gy, respectively) and revertants were counted. TA98 exhibited radiation-induced revertants, 2.8 fold of spontaneous revertants, although no significant increase was detected in TA100. Then, three other frameshift-sensitive strains TA1537, TA1538 and TA94 were irradiated in a dose of 61-167 Gy. Only in TA94, revertants increased 3.5 fold. Since spontaneous revertants are known to be independent of cell density, a decrease of bacterial number by γ irradiation was confirmed not to affect the induced revertants by dilution test. Thus the standard Ames Salmonella assay identified γ irradiation was confirmed not to affect the induced revertants by dilution test. Thus the standard Ames Salmonella assay identified γ irradiation as a mutagenetic agent. The mutagenicity of dinitropyrene, a mutagen widely existing in food, and dismutagenicity of boiling water insoluble fraction of Hizikia fusiforme, edible marine alga, were tested on γ induced revertant formation in TA98 and TA94. Dinitropyrene synergistically increased γ induced revertants and Hizikia insoluble fraction reduced the synergistic effect of dinitropyrene dependently on the concentration. (author)

  20. Brown Adipose Tissue Function Is Enhanced in Long-Lived, Male Ames Dwarf Mice (United States)

    McFadden, Samuel; Fang, Yimin; Huber, Joshua A.; Zhang, Chi; Sun, Liou Y.; Bartke, Andrzej


    Ames dwarf mice (Prop1df/df) are long-lived due to a loss of function mutation, resulting in deficiency of GH, TSH, and prolactin. Along with a marked extension of longevity, Ames dwarf mice have improved energy metabolism as measured by an increase in their oxygen consumption and heat production, as well as a decrease in their respiratory quotient. Along with alterations in energy metabolism, Ames dwarf mice have a lower core body temperature. Moreover, Ames dwarf mice have functionally altered epididymal white adipose tissue (WAT) that improves, rather than impairs, their insulin sensitivity due to a shift from pro- to anti-inflammatory cytokine secretion. Given the unique phenotype of Ames dwarf epididymal WAT, their improved energy metabolism, and lower core body temperature, we hypothesized that Ames dwarf brown adipose tissue (BAT) may function differently from that of their normal littermates. Here we use histology and RT-PCR to demonstrate that Ames dwarf mice have enhanced BAT function. We also use interscapular BAT removal to demonstrate that BAT is necessary for Ames dwarf energy metabolism and thermogenesis, whereas it is less important for their normal littermates. Furthermore, we show that Ames dwarf mice are able to compensate for loss of interscapular BAT by using their WAT depots as an energy source. These findings demonstrate enhanced BAT function in animals with GH and thyroid hormone deficiencies, chronic reduction of body temperature, and remarkably extended longevity. PMID:27740871

  4. NASA Robotic Neurosurgery Testbed (United States)

    Mah, Robert


    The detection of tissue interface (e.g., normal tissue, cancer, tumor) has been limited clinically to tactile feedback, temperature monitoring, and the use of a miniature ultrasound probe for tissue differentiation during surgical operations, In neurosurgery, the needle used in the standard stereotactic CT or MRI guided brain biopsy provides no information about the tissue being sampled. The tissue sampled depends entirely upon the accuracy with which the localization provided by the preoperative CT or MRI scan is translated to the intracranial biopsy site. In addition, no information about the tissue being traversed by the needle (e.g., a blood vessel) is provided. Hemorrhage due to the biopsy needle tearing a blood vessel within the brain is the most devastating complication of stereotactic CT/MRI guided brain biopsy. A robotic neurosurgery testbed has been developed at NASA Ames Research Center as a spin-off of technologies from space, aeronautics and medical programs. The invention entitled "Robotic Neurosurgery Leading to Multimodality Devices for Tissue Identification" is nearing a state ready for commercialization. The devices will: 1) improve diagnostic accuracy and precision of general surgery, with near term emphasis on stereotactic brain biopsy, 2) automate tissue identification, with near term emphasis on stereotactic brain biopsy, to permit remote control of the procedure, and 3) reduce morbidity for stereotactic brain biopsy. The commercial impact from this work is the potential development of a whole new generation of smart surgical tools to increase the safety, accuracy and efficiency of surgical procedures. Other potential markets include smart surgical tools for tumor ablation in neurosurgery, general exploratory surgery, prostate cancer surgery, and breast cancer surgery.

  7. Physical contact influences how much people pay at celebrity auctions. (United States)

    Newman, George E; Bloom, Paul


    Contagion is a form of magical thinking in which people believe that a person's immaterial qualities or essence can be transferred to an object through physical contact. Here we investigate how a belief in contagion influences the sale of celebrity memorabilia. Using data from three high-profile estate auctions, we find that people's expectations about the amount of physical contact between the object and the celebrity positively predicts the final bids for items that belonged to well-liked individuals (e.g., John F. Kennedy) and negatively predicts final bids for items that belonged to disliked individuals (e.g., Bernard Madoff). A follow-up experiment further suggests that these effects are driven by contagion beliefs: when asked to bid on a sweater owned by a well-liked celebrity, participants report that they would pay substantially less if it was sterilized before they received it. However, sterilization increases the amount they would pay for a sweater owned by a disliked celebrity. These studies suggest that magical thinking may still have effects in contemporary Western societies and they provide some unique demonstrations of contagion effects on real-world purchase decisions.

More so, the relationship between celebrity expertise and perceived quality of the product was established.

  6. Communicating the Science from NASA's Astrophysics Missions (United States)

    Hasan, Hashima; Smith, Denise A.


    Communicating science from NASA's Astrophysics missions has multiple objectives, which leads to a multi-faceted approach. While a timely dissemination of knowledge to the scientific community follows the time-honored process of publication in peer reviewed journals, NASA delivers newsworthy research result to the public through news releases, its websites and social media. Knowledge in greater depth is infused into the educational system by the creation of educational material and teacher workshops that engage students and educators in cutting-edge NASA Astrophysics discoveries. Yet another avenue for the general public to learn about the science and technology through NASA missions is through exhibits at museums, science centers, libraries and other public venues. Examples of the variety of ways NASA conveys the excitement of its scientific discoveries to students, educators and the general public will be discussed in this talk. A brief overview of NASA's participation in the International Year of Light will also be given, as well as of the celebration of the twenty-fifth year of the launch of the Hubble Space Telescope.

  8. Mutagenicity of Flavonoids Assayed by Bacterial Reverse Mutation (Ames Test

    Directory of Open Access Journals (Sweden)

    Eliana Aparecida Varanda


    Full Text Available The mutagenicity of ten flavonoids was assayed by the Ames test, in Salmonella typhimurium strains TA98, TA100 and TA102, with the aim of establishing hydroxylation pattern-mutagenicity relationship profiles. The compounds assessed were: quercetin, kaempferol, luteolin, fisetin, chrysin, galangin, flavone, 3-hydroxyflavone, 5-hydroxyflavone and 7-hydroxyflavone. In the Ames assay, quercetin acted directly and its mutagenicity increased with metabolic activation. In the presence of S9 mix, kaempferol and galangin were mutagenic in the TA98 strain and kaempferol showed signs of mutagenicity in the other strains. The absence of hydroxyl groups, as in flavone, only signs of mutagenicity were shown in strain TA102, after metabolization and, among monohydroxylated flavones (3-hydroxyflavone, 5-hydroxyflavone and 7-hydroxyflavone, the presence of hydroxyl groups only resulted in minor changes. Luteolin and fisetin also showed signs of mutagenicity in strain TA102. Finally, chrysin, which has only two hydroxy groups, at the 5-OH and 7-OH positions, also did not induce mutagenic activity in any of the bacterial strains used, under either activation condition. All the flavonoids were tested at concentrations varying from 2.6 to 30.7 nmol/plate for galangin and 12.1 to 225.0 nmol/plate for other flavonoids. In light of the above, it is necessary to clarify the conditions and the mechanisms that mediate the biological effects of flavonoids before treating them as therapeutical agents, since some compounds can be biotransformed into more genotoxic products; as is the case for galangin, kaempferol and quercetin.

  19. Small Worlds Week: An online celebration of planetary science using social media to reach millions (United States)

    Mayo, Louis


    In celebration of the many recent discoveries from New Horizons, Dawn, Rosetta, and Cassini, NASA launched Small Worlds Week, an online, social media driven outreach program leveraging the infrastructure of Sun-Earth Days that included a robust web design, exemplary education materials, hands-on fun activities, multimedia resources, science and career highlights, and a culminating social media event. Each day from July 6-9, a new class of solar system small worlds was featured on the website: Monday-comets, Tuesday-asteroids, Wednesday-icy moons, and Thursday-dwarf planets. Then on Friday, July 10, nine scientists from Goddard Space Flight Center, Jet Propulsion Laboratory, Naval Research Laboratory, and Lunar and Planetary Institute gathered online for four hours to answer questions from the public via Facebook and Twitter. Throughout the afternoon the scientists worked closely with a social media expert and several summer interns to reply to inquirers and to archive their chats. By all accounts, Small Worlds Week was a huge success with 37 million potential views of the social media Q&A posts. The group plans to improve and replicate the program during the school year with a more classroom focus, and then to build and extend the program to be held every year.

  1. NASA, Building Tomorrow's Future (United States)

    Mango, Edward


    We, as NASA, continue to Dare Mighty Things. Here we are in October. In my country, the United States of America, we celebrate the anniversary of Christopher Columbus's arrival in the Americas, which occurred on October 12, 1492. His story, although happening over 500 years ago, is still very valid today. It is a part of the American spirit; part of the international human spirit. Columbus is famous for discovering the new world we now call America, but he probably never envisioned what great discoveries would be revealed many generations later. But in order for Columbus to begin his great adventure, he needed a business plan. Ho would he go about obtaining the funds and support necessary to build, supply, and man the ships required for his travels? He had a lot of obstacles and distractions. He needed a strong, internal drive to achieve his plans and recruit a willing crew of explorers also ready to risk their all for the unknown journey ahead. As Columbus set sail, he said "By prevailing over all obstacles and distractions, one may unfailingly arrive at his chosen goal or destination." Columbus may not have known he was on a journey for all human exploration. Recently, Charlie Bolden, the NASA Administrator, said, "Human exploration is and has always been about making life better for humans on Earth." Today, NASA and the U.S. human spaceflight program hold many of the same attributes as did Columbus and his contemporaries - a willing, can-do spirit. We are on the threshold of exciting new times in space exploration. Like Columbus, we need a business plan to take us into the future. We need to design the best ships and utilize the best designers, with their past knowledge and experience, to build those ships. We need funding and support from governments to achieve these goals of space exploration into the unknown. NASA does have that business plan, and it is an ambitious plan for human spaceflight and exploration. Today, we have a magnificent spaceflight

  2. Attractive celebrity and peer images on Instagram: Effect on women's mood and body image. (United States)

    Brown, Zoe; Tiggemann, Marika


    A large body of research has documented that exposure to images of thin fashion models contributes to women's body dissatisfaction. The present study aimed to experimentally investigate the impact of attractive celebrity and peer images on women's body image. Participants were 138 female undergraduate students who were randomly assigned to view either a set of celebrity images, a set of equally attractive unknown peer images, or a control set of travel images. All images were sourced from public Instagram profiles. Results showed that exposure to celebrity and peer images increased negative mood and body dissatisfaction relative to travel images, with no significant difference between celebrity and peer images. This effect was mediated by state appearance comparison. In addition, celebrity worship moderated an increased effect of celebrity images on body dissatisfaction. It was concluded that exposure to attractive celebrity and peer images can be detrimental to women's body image. Copyright © 2016 Elsevier Ltd. All rights reserved.

  3. The Brand’s Effect on the Evaluation of Advertising Endorsed by Celebrities: an Experimental Study

    Directory of Open Access Journals (Sweden)

    Leonardo Aureliano-Silva


    Full Text Available Celebrity endorsement aims to influence consumers to buy advertised products. In endorsing products, celebrities transfer their attributes to the objects, making them more desired by consumers. Celebrity endorsement is a promotional technique to better integrate brand, product and message, thus justifying the high investments by companies to engage celebrities. Although well established, the phenomenon lacks scientific studies that explain, based on the concept of celebrity congruence, the alignment between the celebrity’s profile and the product, also considering brand strength. After an extensive literature review, we performed three experiments, involving 713 respondents, to verify the effect of celebrity endorsement with different levels of congruence with the product, while manipulating the brands. The results of analysis of variance indicated a significant positive effect of celebrity endorsement with high congruence for unrecognized brands, but not for recognized brands.

  4. Selebtwits: Micro-Celebrity Practitioners in Indonesian Twittersphere

    Directory of Open Access Journals (Sweden)

    Detta Rahmawan


    Full Text Available Drawn from the notion that Twitter is a suitable context for micro-celebrity practices (Marwick, 2010 this research examines interactions between Indonesian Twitter-celebrities called selebtwits and their followers. The results suggest that several strategies include: stimulated conversation, audience recognition, and various level of self-disclosure that have been conducted by the selebtwits to maintain the relationship with their followers. This research also found that from the follower viewpoint, interaction with selebtwits is often perceived as an “endorsement” and “achievement”. However, there are others who are not particularly fond of the idea of the selebtwits-follower’s engagement. Some selebtwits-followers’ interactions lead to “digital intimacy”, while others resemble parasocial interaction and one-way communication. Furthermore, this study suggests that in the broader context, selebtwits are perceived in both positive and negative ways.

  5. Effect of Celebrity Endorsement in Advertising Activities by Product Type

    Directory of Open Access Journals (Sweden)

    Karasiewicz Grzegorz


    Full Text Available This article seeks to answer two related questions: are celebrity endorsements more likely to be result in a higher evaluation of the product being advertised than use of an anonymous individual (e.g. a typical consumer; and, if present, do these positive effects vary by product category? To answer these two questions research was conducted on a 237 student sample employing a quasi-experiment consisting of four groups (two product categories and two types of endorsers using data collected through an online survey. The results indicate that celebrity endorsements do have a positive impact on the evaluation of durable goods, but do not affect the evaluation of frequently purchased products. This finding largely confirms the assumptions of the match-up model, the meaning transfer model, and the ELM model.

  6. Comets, Charisma, and Celebrity: Reflections on Their Deep Impact (United States)

    In celebration of the Deep Impact Mission, this essay explores the influence of comets on the arts and sciences since the beginning of recorded time. Through images, ranging from the sublime to the humorous, it probes the reasons why comets are among the most charismatic visual spectacles in the universe and why, even as scientific missions unmask their mysteries, they remain iconic symbols and harbingers of change.

  7. A historical review of head and neck cancer in celebrities. (United States)

    Folz, B J; Ferlito, A; Weir, N; Pratt, L W; Rinaldo, A; Werner, J A


    The illnesses of celebrity patients always receive more attention from the general public than those of ordinary patients. With regard to cancer, this fact has helped to spread information about the four major malignancies: breast cancer, prostatic cancer, lung cancer and colorectal cancer. Head and neck cancer, on the other hand, is still not well recognised by the lay public, although the risk factors are similar to those of lung cancer. It was the objective of this analysis to identify cases of celebrity patients, the description of which could help to increase awareness of head and neck cancer, its symptoms and risk factors. The Internet and medical literature databases were searched for celebrity patients who had suffered from head and neck cancer. The search revealed numerous famous head and neck cancer patients. However, only seven cases were documented well in the medical literature. Among the identified persons were one emperor, two United States presidents, a legendary composer, a world-renowned medical doctor, an outstanding athlete and an extraordinary entertainer. In spite of their exclusive position in society, these patients did not have a better prognosis compared with ordinary patients of their time. Only two of the group experienced long term survival and only one was cured. None of these influential figures used their influence to fund research or to promote knowledge about their respective diseases. The identified cases could help increase public awareness of head and neck cancer. Similar to activities in other oncologic fields, current celebrity head and neck cancer patients should be encouraged to discuss their diseases openly, which could have a positive effect on public health.

  8. Celebrity Endorsement & Consumer Behavior : Gender Differences as a Marketing Strategy


    Junhem, Sanna; Adolfsson, Sophie


    Background - Celebrity endorsement is not a new phenomenon and it can be seen in advertisements around the world. Since the content of an advertisement easily can be screened out, it is important to target the right consumer. There has to be a fit between the consumer, the endorser and the product. Since gender plays a crucial part when understanding consumer behavior, knowledge about gender differences needs to be taken into account when creating a marketing strategy.      Purpose - Consumer...

  9. EDITORIAL: STAM celebrates its 10th anniversary STAM celebrates its 10th anniversary (United States)

    Ushioda, Sukekatsu


    I would like to extend my warmest greetings to the readers and staff of Science and Technology of Advanced Materials (STAM), on the occasion of its 10th anniversary. Launched in 2000, STAM marks this year an important milestone in its history. This is a great occasion to celebrate. STAM was founded by Tsuyoshi Masumoto in collaboration with Teruo Kishi and Toyonobu Yoshida as a world-class resource for the materials science community. It was initially supported by several materials research societies and was published as a regular peer-reviewed journal. Significant changes occurred in 2008, when the National Institute for Materials Science (NIMS) became solely responsible for all the costs of maintaining the journal. STAM was transformed into an open-access journal published by NIMS in partnership with IOP Publishing. As a result, the publication charges were waived and the entire STAM content, including all back issues, became freely accessible through the IOP Publishing website. The transition has made STAM more competitive and successful in global publication communities, with innovative ideas and approaches. The journal has also changed its publication strategy, aiming to publish a limited number of high-quality articles covering the frontiers of materials science. Special emphasis has been placed on reviews and focus issues, providing recent summaries of hot materials science topics. Publication has become electronic only; however, selected issues are printed and freely distributed at major international scientific events. The Editorial Board has been expanded to include leading experts from all over the world and, together with the Editorial Office, the board members are doing their best to transform STAM into a leading materials science journal. These efforts are paying off, as shown by the rapidly increasing number of article downloads and citations in 2009. I believe that the STAM audience can not only deepen their knowledge in their own specialties but

  10. Ethnography in qualitative educational research: AMEE Guide No. 80. (United States)

    Reeves, Scott; Peller, Jennifer; Goldman, Joanne; Kitto, Simon


    Ethnography is a type of qualitative research that gathers observations, interviews and documentary data to produce detailed and comprehensive accounts of different social phenomena. The use of ethnographic research in medical education has produced a number of insightful accounts into its role, functions and difficulties in the preparation of medical students for clinical practice. This AMEE Guide offers an introduction to ethnography - its history, its differing forms, its role in medical education and its practical application. Specifically, the Guide initially outlines the main characteristics of ethnography: describing its origins, outlining its varying forms and discussing its use of theory. It also explores the role, contribution and limitations of ethnographic work undertaken in a medical education context. In addition, the Guide goes on to offer a range of ideas, methods, tools and techniques needed to undertake an ethnographic study. In doing so it discusses its conceptual, methodological, ethical and practice challenges (e.g. demands of recording the complexity of social action, the unpredictability of data collection activities). Finally, the Guide provides a series of final thoughts and ideas for future engagement with ethnography in medical education. This Guide is aimed for those interested in understanding ethnography to develop their evaluative skills when reading such work. It is also aimed at those interested in considering the use of ethnographic methods in their own research work.

  11. Mobile technologies in medical education: AMEE Guide No. 105. (United States)

    Masters, Ken; Ellaway, Rachel H; Topps, David; Archibald, Douglas; Hogue, Rebecca J


    Mobile technologies (including handheld and wearable devices) have the potential to enhance learning activities from basic medical undergraduate education through residency and beyond. In order to use these technologies successfully, medical educators need to be aware of the underpinning socio-theoretical concepts that influence their usage, the pre-clinical and clinical educational environment in which the educational activities occur, and the practical possibilities and limitations of their usage. This Guide builds upon the previous AMEE Guide to e-Learning in medical education by providing medical teachers with conceptual frameworks and practical examples of using mobile technologies in medical education. The goal is to help medical teachers to use these concepts and technologies at all levels of medical education to improve the education of medical and healthcare personnel, and ultimately contribute to improved patient healthcare. This Guide begins by reviewing some of the technological changes that have occurred in recent years, and then examines the theoretical basis (both social and educational) for understanding mobile technology usage. From there, the Guide progresses through a hierarchy of institutional, teacher and learner needs, identifying issues, problems and solutions for the effective use of mobile technology in medical education. This Guide ends with a brief look to the future.

    CERN Bulletin


    On 29 September, CERN celebrated its 60th anniversary with a gala celebration. Hundreds of CERN staff members and users, dignitaries from CERN Member States and representatives of international organisations filled the marquee for a ceremony featuring speeches as well as music from the EU Youth Orchestra. CERN Recruitment Unit section leader Anna Cook was called in at the last minute to host the ceremony.   Anna had just got back from a run on her day off when she got the call. On the line CERN60 project leader Sascha Schmeling, Globe manager Bernard Pellequer and video editor Jacques Fichet had a problem.

  14. Praising as bodily practice: the neocharismatic culture of celebration

    Directory of Open Access Journals (Sweden)

    Tuija Hovi


    Full Text Available Rhythmic body movements and dancing, as well as singing, have been used as a means and inspiration for both individual and communal spiritual experience throughout the history of religions. This article takes a tentative look at the contemporary neocharismatic culture of celebration as a means of aiming at religious experience through collective bodily practice; namely praising, which is generally understood to take the form of singing but is, in fact, expressed also in bodily movements such as dancing. In the neocharismatic context, a celebration means a certain type of a meeting with a special focus on contemplative worship and prayer, accompanied with lively music of praise. First, the historical background of the neo­charismatic branch is outlined shortly. Secondly, the tradition of praise itself within this context is described – what are the insider definitions and what kinds of forms praise in the culture of celebration actually includes, especially in Finland. The description is basically based on internet material and the author's previous field experiences in the Word of Life congregational meetings and other charismatic Christian events. In conclusion, acts of praise as a source of religious experience are discussed.

  15. College Women's Responses to a Celebrity Health Disclosure. (United States)

    Drizin, Julia H; Malcarne, Vanessa L; Schiaffino, Melody K; Wells, Kristen J


    Celebrities can have a powerful influence on people's health-related attitudes and behaviors, often by publicly disclosing their own personal health decisions. In May 2013, Angelina Jolie, an internationally recognized actress, director, and author, wrote an op-ed for the New York Times disclosing her decision to undergo a prophylactic double mastectomy to reduce her risk of breast cancer after learning that she carried the BRCA1 gene mutation. This cross-sectional study examined whether exposure to Angelina Jolie and her mastectomy disclosure and parasocial involvement (PSI) with Angelina Jolie were related to female college students' perceived risk of breast cancer and breast cancer screening intentions. Participants were 198 female undergraduate college students. Data were collected anonymously via an online questionnaire and analyzed using bivariate correlations and hierarchical linear regression analyses. Neither exposure to Angelina and her disclosure nor PSI with Angelina Jolie was related to participants' attitudes or behaviors related to breast cancer. However, having a family history of cancer was associated with more exposure to Angelina Jolie and her disclosure. Findings suggest that exposure to and PSI with a celebrity who has disclosed a health-related message may not be sufficient to motivate young women to change their health-related attitudes and behaviors. Future studies should explore how celebrities disclosing different types of health issues might influence the attitudes and behaviors of young women.

  16. Celebrity Endorsement And Attitude A Study To Assess The Impact Of Celebrity Endorsement On Attitude Of Consumers

    Directory of Open Access Journals (Sweden)

    Radhika Wadhera


    Full Text Available The term Celebrity refers to an individual who is known to the public actor sports figure entertainer etc. for his or her achievements in areas other than that of the product class endorsed Friedman and Friedman 1979. The objective of this research paper was to examine the celebrity endorsements impact on companies and buying behaviour of customer.

    The U. S. Department of Energy's Ames Laboratory in Ames, Iowa was a coalition partner for outreach activities connected with NOVA's Making Stuff television series on PBS. Volunteers affiliated with the Ames Laboratory and Iowa State University, with backgrounds in materials science, took part in activities including a science-themed Family Night at a local mall, Science Cafes at the Science Center of Iowa, teacher workshops, demonstrations at science nights in elementary and middle schools, and various other events. We describe a selection of the activities and present a summary of their outcomes and extent of their impact on Ames, Des Moines and the surrounding communities in Iowa. In Part 2, results of a volunteer attitude survey are presented, which shed some light on the volunteer experience and show how the volunteers participation in outreach activities has affected their views of materials education.

  18. Acquisition of steady-state operant behavior in long-living Ames Dwarf mice. (United States)

    Derenne, Adam; Brown-Borg, Holly; Feltman, Kathryn; Corbett, Grant; Lackman, Serena


    Ames dwarf mice have a Prop-1 mutation that has been identified with increased levels of IGF-I in the central nervous system, upregulation of neuroprotective systems, and increased lifespan. To elucidate the behavioral effects of the Prop-1 mutation, 8 Ames dwarf and 7 normal mice (all of whom were 8 months of age or younger) were compared on a differential-reinforcement-of-low-rate-of-responding schedule of reinforcement and a matching-to-sample task. On both tasks, nosepokes were reinforced with access to a saccharin solution. Comparisons were based on several measures of behavioral efficiency: pause durations, intertrial intervals, and numbers of responses. Ames dwarf mice were generally less efficient than normal mice. One possible cause of this outcome is that relatively young Ames dwarf mice show less cognitive development than age-matched normal mice. Copyright © 2011 Elsevier Inc. All rights reserved.

  19. Analysis of Hexanitrostilbene (HNS) and Dipicryethane (DPE) for Mutagenicity by the Ames/Salmonella Assay

    Energy Technology Data Exchange (ETDEWEB)

    Wu, R; Felton, J


    The Ames/Salmonella assay, developed by Professor Bruce Ames at the University of California, Berkeley, is a rapid and sensitive assay for detecting mutagenicity of various chemical compounds (Maron and Ames, 1983). It is a widely accepted short-term assay for detecting chemicals that induce mutations in the histidine (his) gene of Salmonella typhimurium. This is a reverse mutation assay that detects the mutational reversion of his-dependent Salmonella to the his-independent counterpart. Thereby, mutagenic compounds will increase the frequency of occurrence of his-independent bacterial colonies. The assay utilizes the specific genetically constructed strains of bacteria either with or without mammalian metabolic activation enzymes (S9), Aroclor induced rat liver homogenate to assess the mutagenicity of different compounds. In this study, we will use the Ames/Salmonella assay to investigate the mutagenicity of Hexanitrostilbene (HNS) from both Bofors and Pantex, and Dipicryethane (DPE).

  20. Biological, psychological and social processes that explain celebrities' influence on patients' health-related behaviors. (United States)

    Hoffman, Steven J; Tan, Charlie


    Celebrities can have substantial influence as medical advisors. However, their impact on public health is equivocal: depending on the advice's validity and applicability, celebrity engagements can benefit or hinder efforts to educate patients on evidence-based practices and improve their health literacy. This meta-narrative analysis synthesizes multiple disciplinary insights explaining the influence celebrities have on people's health-related behaviors. Systematic searches of electronic databases BusinessSource Complete, Communication & Mass Media Complete, Humanities Abstracts, ProQuest Political Science, PsycINFO, PubMed, and Sociology Abstracts were conducted. Retrieved articles were used to inform a conceptual analysis of the possible processes accounting for the substantial influence celebrities may have as medical advisors. Fourteen mechanisms of celebrity influence were identified. According to the economics literature, celebrities distinguish endorsed items from competitors and can catalyze herd behavior. Marketing studies tell us that celebrities' characteristics are transferred to endorsed products, and that the most successful celebrity advisors are those viewed as credible, a perception they can create with their success. Neuroscience research supports these explanations, finding that celebrity endorsements activate brain regions involved in making positive associations, building trust and encoding memories. The psychology literature tells us that celebrity advice conditions people to react positively toward it. People are also inclined to follow celebrities if the advice matches their self-conceptions or if not following it would generate cognitive dissonance. Sociology explains how celebrities' advice spreads through social networks, how their influence is a manifestation of people's desire to acquire celebrities' social capital, and how they affect the ways people acquire and interpret health information. There are clear and deeply rooted biological

    International Nuclear Information System (INIS)

    Audi, G; Wang, M.; Wapstra, A.H.; Kondev, F.G.; MacCormick, M.; Xu, X.; Pfeiffer, B.


    This paper is the first of two articles (Part I and Part II) that presents the results of the new atomic mass evaluation, Ame2012. It includes complete information on the experimental input data (including not used and rejected ones), as well as details on the evaluation procedures used to derive the tables with recommended values given in the second part. This article describes the evaluation philosophy and procedures that were implemented in the selection of specific nuclear reaction, decay and mass-spectrometer results. These input values were entered in the least-squares adjustment procedure for determining the best values for the atomic masses and their uncertainties. Calculation procedures and particularities of the AME are then described. All accepted and rejected data, including outweighed ones, are presented in a tabular format and compared with the adjusted values (obtained using the adjustment procedure). Differences with the previous Ame2003 evaluation are also discussed and specific information is presented for several cases that may be of interest to various AME users. The second Ame2012 article, the last one in this issue, gives a table with recommended values of atomic masses, as well as tables and graphs of derived quantities, along with the list of references used in both this Ame2012 evaluation and the Nubase2012 one (the first paper in this issue).

  2. Mitochondrial electron transport chain functions in long-lived Ames dwarf mice (United States)

    Choksi, Kashyap B.; Nuss, Jonathan E.; DeFord, James H.; Papaconstantinou, John


    The age-associated decline in tissue function has been attributed to ROS-mediated oxidative damage due to mitochondrial dysfunction. The long-lived Ames dwarf mouse exhibits resistance to oxidative stress, a physiological characteristic of longevity. It is not known, however, whether there are differences in the electron transport chain (ETC) functions in Ames tissues that are associated with their longevity. In these studies we analyzed enzyme activities of ETC complexes, CI-CV and the coupled CI-CII and CII-CIII activities of mitochondria from several tissues of young, middle aged and old Ames dwarf mice and their corresponding wild type controls to identify potential mitochondrial prolongevity functions. Our studies indicate that post-mitotic heart and skeletal muscle from Ames and wild-type mice show similar changes in ETC complex activities with aging, with the exception of complex IV. Furthermore, the kidney, a slowly proliferating tissue, shows dramatic differences in ETC functions unique to the Ames mice. Our data show that there are tissue specific mitochondrial functions that are characteristic of certain tissues of the long-lived Ames mouse. We propose that this may be a factor in the determination of extended lifespan of dwarf mice. PMID:21934186

  3. Hepatic response to oxidative injury in long-lived Ames dwarf mice. (United States)

    Sun, Liou Y; Bokov, Alex F; Richardson, Arlan; Miller, Richard A


    Multiple stress resistance pathways were evaluated in the liver of Ames dwarf mice before and after exposure to the oxidative toxin diquat, seeking clues to the exceptional longevity conferred by this mutation. Before diquat treatment, Ames dwarf mice, compared with nonmutant littermate controls, had 2- to 6-fold higher levels of expression of mRNAs for immediate early genes and 2- to 5-fold higher levels of mRNAs for genes dependent on the transcription factor Nrf2. Diquat led to a 2-fold increase in phosphorylation of the stress kinase ERK in control (but not Ames dwarf) mice and to a 50% increase in phosphorylation of the kinase JNK2 in Ames dwarf (but not control) mice. Diquat induction of Nrf2 protein was higher in dwarf mice than in controls. Of 6 Nrf2-responsive genes evaluated, 4 (HMOX, NQO-1, MT-1, and MT-2) remained 2- to 10-fold lower in control than in dwarf liver after diquat, and the other 2 (GCLM and TXNRD) reached levels already seen in dwarf liver at baseline. Thus, livers of Ames dwarf mice differ systematically from controls in multiple stress resistance pathways before and after exposure to diquat, suggesting mechanisms for stress resistance and extended longevity in Ames dwarf mice.

  11. The colonization of a celebration: The transformations of Krsna Slava

    Directory of Open Access Journals (Sweden)

    Sabina Hadžibulić


    Full Text Available The article discusses the Slava, or Krsna Slava – traditionally, a Serbian Orthodox celebration of a family’s patron saint. During Real Socialism, the custom was disapproved by the régime because of its religious content. After the collapse of Real Socialism and the disintegration of the Yugoslav federal state, the scale, context and meaning of the Slava have all changed. At the same time as the private celebrations have become larger, less secluded, and a target for marketing, a new type of Slavas has emerged as well. They are not related to a family, but to an organization. Both private and public organizations, including public schools and government offices, stage Slavas as public celebrations. The festivities display a mix of religious and nationalist elements. From a neo-institutionalist perspective, we interpret the change as an example of changing relationships between the state and civil society institutions. The Republic of Serbia has taken the course of re-building its citizenry’s national identity on the basis of Serbian ethnicity instead of the former, supra-ethnic Yugoslav identity. In its search for legitimacy, the new state seeks support both from the Serbian Orthodox Church and from traditions that can be understood as distinctly Serbian. During Real Socialism, the Slava contributed to the reproduction of a traditionalist, religious and family-centered identity, which was a competitor to that of the citizen of a Socialist state. Now, the state is instead promoting the Slava, at the same time using it as a means of representing the state as an expression of exclusively Serbian ethnicity.

  19. Ames-2016 line lists for 13 isotopologues of CO2: Updates, consistency, and remaining issues (United States)

    Huang (黄新川), Xinchuan; Schwenke, David W.; Freedman, Richard S.; Lee, Timothy J.


    A new 626-based Ames-2 PES refinement and Ames-2016 line lists for 13 CO2 isotopologues are reported. A consistent σRMS = ±0.02 cm-1 is established for hundreds of isotopologue band origins using the Ames-2 PES. Ames-2016 line lists are computed at 296 K, 1000 K and 4000 K using the Ames-2 PES and the same DMS-N2 dipole surface used previously, with J up to 150, E‧ up to 24,000 cm-1 or 18,000 cm-1 and appropriate intensity cutoffs. The lists are compared to the CDSD-296, CDSD-4000 databases, UCL line lists, and a few recent highly accurate CO2 intensity measurements. Both agreements and discrepancies are discussed. Compared to the old Ames CO2 lists, the Ames-2016 line lists have line position deviations reduced by 50% or more, which consequently leads to more reliable intensities. The line shape parameters in the Ames-2016 line lists are predicted using the newly assigned conventional vibrational polyad quantum numbers for rovibrational levels below 12,000 cm-1 so the quality of the line shape parameters is similar to that of CDSD or HITRAN. This study further proves that a semi-empirically refined PES (Ames-1 and Ames-2) coupled with a high quality ab initio DMS (DMS-N2 and UCL) may generate IR predictions with consistent accuracy and is thus helpful in the analysis of laboratory spectra and simulations of various isotopologues. The Ames-2016 lists based on DMS-N2 have reached the ∼1% intensity prediction accuracy level for the recent 626 30013-00001 and 20013-00001 bands, but further quantification and improvements require sub-percent or sub-half-percent accurate experimental intensities. The inter-isotopologue consistency of the intensity prediction accuracies should have reached better than 1-3% for regular bands not affected by resonances. Since the Effective Dipole Models (EDM) in CDSD and HITRAN have 1-20% or even larger uncertainties, we show that the Ames lists can provide better alternative IR data for many hard-to-determine isotopologue bands

  20. Resolution of contradiction between in silico predictions and Ames test results for four pharmaceutically relevant impurities. (United States)

    Gunther, William C; Kenyon, Michelle O; Cheung, Jennifer R; Dugger, Robert W; Dobo, Krista L


    The ICH M7 Guideline requires low level control of mutagenic impurities in pharmaceutical products to minimize cancer risk in patients (ICHM7, 2014). Bacterial mutagenicity (Ames) data is generally used to determine mutagenic and possible carcinogenic potential of compounds. Recently, a publication on experiences of using two in silico systems to identify potentially mutagenic impurities highlighted the importance of performing a critical review of published Ames data utilized as part of a mutagenicity assessment of impurities (Greene et al., 2015). Four compounds (2-amino-5-hydroxybenzoic acid, 2-amino-3-chlorobenzoic acid, methyl 2-amino-4-chlorobenzoate and 4-morpholinopyridine) reported mutagenic were identified in a two system in silico assessment and expert review of the structuresas non-mutagenic. Likely reasons for mutagenicity could not be identified and the purity of the compounds tested was proposed. In the current investigation, the purest available sample of the four compounds was tested in an OECD-compliant Ames test. The compounds were all found to be non-mutagenic. Possible reasons for the discrepancy between previously reported and current results are discussed. Additionally, important points to consider when conducting an expert review of available Ames data are provided particularly in cases where reported Ames results are discrepant with a two system in silico assessment.

  2. Intense-personal celebrity worship and body image: evidence of a link among female adolescents. (United States)

    Maltby, John; Giles, David C; Barber, Louise; McCutcheon, Lynn E


    The aim of the present study was to examine the relationship between celebrity worship and body image within the theoretical perspective of intense para-social relationships with celebrities. Correlation and multiple regression analyses were used to examine the relationships between celebrity worship and body image. Three samples, 229 (102 males and 127 females) adolescents, 183 (88 males and 95 females) full-time university undergraduate students, and 289 (126 males and 163 females) adults were administered an amended version of the Celebrity Attitude Scale, the Attention to Body Shape Scale, and the Body Shape Questionnaire-Revised. Significant relationships were found between attitudes toward celebrities and body image only among female adolescents. Multiple regression analyses suggested that Intense-personal celebrity worship accounted for unique variance in scores in body image. Findings suggest that in female adolescents, there is an interaction between Intense-personal celebrity worship and body image between the ages of 14 and 16 years, and some tentative evidence has been found to suggest that this relationship disappears at the onset of adulthood, 17 to 20 years. Results are consistent with those authors who stress the importance of the formation of para-social relationships with media figures, and suggest that para-social relationships with celebrities perceived as having a good body shape may lead to a poor body image in female adolescents.

    Bonin, Patrick; Perret, Cyril; Méot, Alain; Ferrand, Ludovic; Mermillod, Martial


    A set of 105 photographs of celebrities has been standardized in French on distinctiveness, proper name agreement, face agreement, age of acquisition (AoA), and subjective frequency. Statistics on the collected variables for photographs are provided. The relationships between these variables have been analyzed. Face naming latencies have also been collected for the photographs of celebrities, and several multiple regression analyses have been carried out on naming latencies and percentages of tip-of-the-tongue (TOT) phenomena. Themain determinants of naming speed included AoA, face agreement, and name agreement. In addition, AoA, together with distinctiveness and face agreement, reliably predicted the percentages of TOTs. The norms, photographs of the celebrities, and spoken naming latencies corresponding to the celebrities are available on the Internet at and should be of great use to researchers interested in the processing of famous people.

  5. The Role of Gender on Consumer Attitudes toward Multiple Celebrity Advertisements

    Directory of Open Access Journals (Sweden)

    Işık Özge YUMURTACI


    Full Text Available Although its has been widely used in advertising, the impact of multiple celebrity endorsement on consumers has not been known. Therefore, the aim of this study is to examine whether consumers’ attitudes towards advertisement and brand, and their purchase intention differ regarding to the gender of consumers in multiple celebrity endorsement. Hence, survey study was conducted with 256 individuals. The findings of this study indicates that when two celebrities are used in an advertisement, based on the consumers’ attitudes towards the celebrities, the attitudes towards advertisement and brand, and purchase intentions may show discrepancies according to the gender of consumers. This study may shed light on how to use multiple celebrities in companies’ marketing strategies in a more accurate and effective way while considering consumer gender differences

  12. Revalidation of the NASA Ames 11-by 11-Foot Transonic Wind Tunnel with a Commercial Airplane Model (United States)

    Kmak, Frank J.; Hudgins, M.; Hergert, D.; George, Michael W. (Technical Monitor)


    The 11-By 11-Foot Transonic leg of the Unitary Plan Wind Tunnel (UPWT) was modernized to improve tunnel performance, capability, productivity, and reliability. Wind tunnel tests to demonstrate the readiness of the tunnel for a return to production operations included an Integrated Systems Test (IST), calibration tests, and airplane validation tests. One of the two validation tests was a 0.037-scale Boeing 777 model that was previously tested in the 11-By 11-Foot tunnel in 1991. The objective of the validation tests was to compare pre-modernization and post-modernization results from the same airplane model in order to substantiate the operational readiness of the facility. Evaluation of within-test, test-to-test, and tunnel-to-tunnel data repeatability were made to study the effects of the tunnel modifications. Tunnel productivity was also evaluated to determine the readiness of the facility for production operations. The operation of the facility, including model installation, tunnel operations, and the performance of tunnel systems, was observed and facility deficiency findings generated. The data repeatability studies and tunnel-to-tunnel comparisons demonstrated outstanding data repeatability and a high overall level of data quality. Despite some operational and facility problems, the validation test was successful in demonstrating the readiness of the facility to perform production airplane wind tunnel%, tests.

    International Nuclear Information System (INIS)


    On March 5, 1992, a Department of Energy (DOE) Tiger Team completed an assessment of the Ames Laboratory, located in Ames, Iowa. The purpose of the assessment was to provide the Secretary of Energy with a report on the status and performance of Environment, Safety and Health (ES ampersand H) programs at Ames Laboratory. Detailed findings of the assessment are presented in the report, DOE/EH-0237, Tiger Team Assessment of the Ames Laboratory. This document, the Ames Laboratory Corrective Action Plan (ALCAP), presents corrective actions to overcome deficiencies cited in the Tiger Team Assessment. The Tiger Team identified 53 Environmental findings, from which the Team derived four key findings. In the Safety and Health (S ampersand H) area, 126 concerns were identified, eight of which were designated Category 11 (there were no Category I concerns). Seven key concerns were derived from the 126 concerns. The Management Subteam developed 19 findings which have been summarized in four key findings. The eight S ampersand H Category 11 concerns identified in the Tiger Team Assessment were given prompt management attention. Actions to address these deficiencies have been described in individual corrective action plans, which were submitted to DOE Headquarters on March 20, 1992. The ALCAP includes actions described in this early response, as well as a long term strategy and framework for correcting all remaining deficiencies. Accordingly, the ALCAP presents the organizational structure, management systems, and specific responses that are being developed to implement corrective actions and to resolve root causes identified in the Tiger Team Assessment. The Chicago Field Office (CH), IowaState University (ISU), the Institute for Physical Research and Technology (IPRT), and Ames Laboratory prepared the ALCAP with input from the DOE Headquarters, Office of Energy Research (ER)

    A major concern in studies related to carcinogenesis is the exposure to the exogenous carcinogens that may occur in food in both natural and polluted human environments. The purpose of the present study is to examine some of food products by Ames test to find out if food products carcinogenic then expose food to gamma radiation to find out the effect of radiation on it as a treatment. In this study, the food samples were examined by Ames test (Salmonella typhimurium mutagenicity test) to find out that a food product could be carcinogenic or highly mutated. Testing of chemicals for mutagenicity is based on the knowledge that a substance which is mutagenic in the bacterium is more likely than not to be a carcinogen in laboratory animals, and thus , by extension, present a risk of cancer to humans. After that food products that showed mutagenicity exposed to gamma radiation at different doses to examine the effect of gamma radiation on food products. This study represent γ radiation effect on carcinogenic food by using Ames test in the following steps: Detect food by Ames test using Salmonella typhimurium strains in which the colony count /plate for each food sample will show if food is slightly mutated or highly mutated or carcinogenic. If food is highly mutated or carcinogenic with high number of colonies /plate, then the carcinogenic food or highly mutated food exposed to different doses of radiation The applied doses in this study were 0, 2.5, 5, and 10 (KGy). Detect the radiation effect on food samples by Ames test after irradiation. The study shows that mutated and carcinogenic food products estimated by Ames test could be treated by irradiation

    Fretter, E. F. (Editor); Kuhns, Jay (Editor); Nuez, Jay (Editor)


    The Ames Arc Jet Complex has a rich heritage of over 40 years in Thermal Protection System (TPS) development for every NASA Space Transportation and Planetary program, including Apollo, Space Shuttle, Viking, Pioneer-Venus, Galileo, Mars Pathfinder,Stardust, NASP,X-33,X-34,SHARP-B1 and B2,X-37 and Mars Exploration Rovers. With this early TPS history came a long heritage in the development of the arc jet facilities. These are used to simulate the aerodynamic heating that occurs on the nose cap, wing leading edges and on other areas of the spacecraft requiring thermal protection. TPS samples have been run in the arc jets from a few minutes to over an hour,from one exposure to multiple exposures of the same sample, in order t o understand the TPS materials response to a hot gas flow environment (representative of real hyperthermal environments experienced in flight). The Ames Arc l e t Complex is a key enabler for customers involved in the three major areas of TPS development: selection, validation, and qualification. The arc jet data are critical for validating TPS thermal models, heat shield designs and repairs, and ultimately for flight qualification.

    Willmar Sauter


    Full Text Available James Joyce had decided that 16 June 1904 should be the one day in the life of Leopold Bloom, about which he wrote his 800 page novel Ulysses. In his book, Joyce actually followed Mr Bloom that entire day, from his getting up and having the nowadays famous kidney breakfast, to the late evening, when he had to break into his own house on 7 Eccle Street to have a drink with Stephen Dedalus, the other main figure of the novel. The centenary of that very day took, accordingly, place in 2004. I have borrowed the identity of Mr Bloom to describe some street scenes from the centennial celebrations of Bloomsday in Dublin. After this intro-ductory presentation, part two of this article will attempt to analyse Bloomsday in terms of a Theatrical Event, embedded in an unusual and striking playing culture. In a third part, Mr Bloom will once more be allowed to make some concluding comments.

    In celebration of the 100th year of International Women’s Day on 8 March, a special colloquium looking at high energy physics from a gender studies perspective was held at CERN.   Addressing a packed conference room, Helene Goetschel, a visiting gender studies researcher from Uppsala University, gave a presentation on a subject unfamiliar to most physicists: sociology. And more specifically, on the findings of gender researchers examining the field of high energy physics. “It was heartening to see so many CERN physicists interested in hearing how sociologists and historians see their community,” said Helene. “Examining our personal issues with gender is difficult, and I applaud anyone who takes an interest in the subject.” Helene Goetschel began her academic career in high-energy physics, but encountered a 'glass ceiling' in her work. In 1990, she decided to change the focus of her studies to the history of science – specifically looking ...

  19. Celebrity Influence and Identification: A Test of the Angelina Effect. (United States)

    Kosenko, Kami A; Binder, Andrew R; Hurley, Ryan


    Angelina Jolie's announcement that she is a BRCA1 carrier and has had a prophylactic bilateral mastectomy was met with widespread support as well as speculation about its possible impact on the public. These speculations were the subject of a Time magazine cover story titled "The Angelina Effect" (Kluger et al., 2013 ). Although there is anecdotal evidence to support this hypothesized Angelina effect, empirical tests are lacking. To explore possible links between Angelina's announcement and public health, we surveyed 356 adults immediately after the announcement. Guided by a model of celebrity influence, the survey assessed participants' demographics and health history, identification and parasocial interaction with Jolie, and genetic testing intentions. Results supported the model's predictions and provided preliminary evidence of an Angelina effect.

  7. Celebrity suicides and their differential influence on suicides in the general population: a national population-based study in Korea. (United States)

    Myung, Woojae; Won, Hong-Hee; Fava, Maurizio; Mischoulon, David; Yeung, Albert; Lee, Dongsoo; Kim, Doh Kwan; Jeon, Hong Jin


    Although evidence suggests that there is an increase in suicide rates in the general population following celebrity suicide, the rates are heterogeneous across celebrities and countries. It is unclear which is the more vulnerable population according to the effect sizes of celebrity suicides to general population. All suicide victims in the general population verified by the Korea National Statistical Office and suicides of celebrity in South Korea were included for 7 years from 2005 to 2011. Effect sizes were estimated by comparing rates of suicide in the population one month before and after each celebrity suicide. The associations between suicide victims and celebrities were examined. Among 94,845 suicide victims, 17,209 completed suicide within one month after 13 celebrity suicides. Multivariate logistic regression analyses revealed that suicide victims who died after celebrity suicide were significantly likely to be of age 20-39, female, and to die by hanging. These qualities were more strongly associated among those who followed celebrity suicide with intermediate and high effect sizes than lower. Younger suicide victims were significantly associated with higher effect size, female gender, white collar employment, unmarried status, higher education, death by hanging, and night-time death. Characteristics of celebrities were significantly associated with those of general population in hanging method and gender. Individuals who commit suicide after a celebrity suicide are likely to be younger, female, and prefer hanging as method of suicide, which are more strongly associated in higher effect sizes of celebrity suicide.

  12. The Role of Synthetic Biology in NASA's Missions (United States)

    Rothschild, Lynn J.


    The time has come to for NASA to exploit synthetic biology in pursuit of its missions, including aeronautics, earth science, astrobiology and most notably, human exploration. Conversely, NASA advances the fundamental technology of synthetic biology as no one else can because of its unique expertise in the origin of life and life in extreme environments, including the potential for alternate life forms. This enables unique, creative "game changing" advances. NASA's requirement for minimizing upmass in flight will also drive the field toward miniaturization and automation. These drivers will greatly increase the utility of synthetic biology solutions for military, health in remote areas and commercial purposes. To this end, we have begun a program at NASA to explore the use of synthetic biology in NASA's missions, particular space exploration. As part of this program, we began hosting an iGEM team of undergraduates drawn from Brown and Stanford Universities to conduct synthetic biology research at NASA Ames Research Center. The 2011 team ( produced an award-winning project on using synthetic biology as a basis for a human Mars settlement.

    Full Text Available The Nigerian economy has experienced increased launching of consumer products; this is occasioned by the level of competition in the country. As such consumers are exposed to large number of product-related communication messages in primetime television and newspaper content. One commonly strategy adopted by manufacturers of consumer products is the use of celebrity endorsement with it attendance cost and other risks. The main objective of this study is to establish if there is a relationship between brand positioning, purchasing decisions, brand equity and celebrity endorsement. A survey of 142 respondents was used and the data was analyzed with Structural Equation Model. The results indicate that trust, level of expertise and the fit between the celebrity and the product have positive impact on product performance. However, it was discovered that attractiveness of the celebrity and the similarities between the celebrity and the receiver has little effect on product performance. Therefore, organizations desirous of making use of celebrity in promoting their products should evaluate the attributes of the celebrities that will enhance product performance.

  17. Ames hypopituitary dwarf mice demonstrate imbalanced myelopoiesis between bone marrow and spleen. (United States)

    Capitano, Maegan L; Chitteti, Brahmananda R; Cooper, Scott; Srour, Edward F; Bartke, Andrzej; Broxmeyer, Hal E


    Ames hypopituitary dwarf mice are deficient in growth hormone, thyroid-stimulating hormone, and prolactin. The phenotype of these mice demonstrates irregularities in the immune system with skewing of the normal cytokine milieu towards a more anti-inflammatory environment. However, the hematopoietic stem and progenitor cell composition of the bone marrow (BM) and spleen in Ames dwarf mice has not been well characterized. We found that there was a significant decrease in overall cell count when comparing the BM and spleen of 4-5 month old dwarf mice to their littermate controls. Upon adjusting counts to differences in body weight between the dwarf and control mice, the number of granulocyte-macrophage progenitors, confirmed by immunophenotyping and colony-formation assay was increased in the BM. In contrast, the numbers of all myeloid progenitor populations in the spleen were greatly reduced, as confirmed by colony-formation assays. This suggests that there is a shift of myelopoiesis from the spleen to the BM of Ames dwarf mice; however, this shift does not appear to involve erythropoiesis. The reasons for this unusual shift in spleen to marrow hematopoiesis in Ames dwarf mice are yet to be determined but may relate to the decreased hormone levels in these mice. Copyright © 2015.

    This paper is the first of two parts presenting the result of a new evaluation of atomic masses (AME2003). In this first part we give full information on the used and rejected input data and on the procedures used in deriving the tables in the second part. We first describe the philosophy and procedures used in selecting nuclear-reaction, decay, and mass spectrometric results as input values in a least-squares evaluation of best values for atomic masses. The calculation procedures and particularities of the AME are then described. All accepted data, and rejected ones with a reported precision still of interest, are presented in a table and compared there with the adjusted values. The differences with the earlier evaluation are briefly discussed and information is given of interest for the users of this AME. The second paper for the AME2003, last in this issue, gives a table of atomic masses, tables and graphs of derived quantities, and the list of references used in both this evaluation and the NUBASE2003 table (first paper in this issue).

    Debarberis, L.; Estorff, U. von; Crutzen, S.; Beers, M.; Stamm, H.; Vries, M.I. de; Tjoa, G.L.


    Within the framework of the European Network AMES, Ageing Materials evaluation and Studies, a number of experimental works on RPV materials embrittlement are carried out at the Institute of Advanced Materials (AIM) of the Joint Research Centre (JRC) of the European Commission (EC). The objectives of AMES are mainly the understanding of the property degradation phenomena of RPV western reference steels like JRQ and HSST, eastern RPV steels like 15X2mFA and 15H2X15, and annealing possibilities. In order to conduct a very high quality irradiation rig, LYRA facility, has been designed and developed at the High Flux Reactor (HFR) Petten. An other dedicated rig, named LIMA, has been developed at the HFR Petten in order to irradiate RPV steels, internals and in-core materials under typical BWR/PWR conditions. The samples can be irradiated in pressurised water up to 160 bar, 320 deg. C, and the water chemistry fully controlled. For irradiation of standard or miniaturised LWR related materials samples, another group of well experienced irradiation devices with inert gas or liquid metals environment are employed. These devices are tailored to their various specific applications. This paper is intended to give information about the structure and the objectives of the existing European network AMES, and to present the various AMES main and spin-off projects, including a brief description on he modelling activities related to RPV materials embrittlement.

    Online surveys were conducted to determine the impact of endorser credibility, endorser effectiveness, and consumers' involvement in direct-to-consumer advertising. In a randomized posttest only study, using the elaboration likelihood model, survey participants (U.S. adults) were either exposed to a fictitious prescription drug ad with a celebrity or a noncelebrity endorser. There was no significant difference in credibility and effectiveness between the celebrity and the noncelebrity endorser. High involvement consumers viewed the ad more favorably and exhibited significantly stronger drug inquiry intentions during their next doctor visit. Further, consumers' involvement did not moderate the effect of celebrity endorser.

  7. Expression of oxidative phosphorylation components in mitochondria of long-living Ames dwarf mice. (United States)

    Brown-Borg, Holly M; Johnson, W Thomas; Rakoczy, Sharlene G


    Reduced signaling of the growth hormone (GH)/insulin-like growth factor-1 (IGF-1) pathway is associated with extended life span in several species. Ames dwarf mice are GH-deficient and live >50% longer than wild-type littermates. Previously, we have shown that tissues from Ames mice exhibit elevated levels of antioxidative enzymes, less H(2)O(2) production, and lower oxidative damage suggesting that mitochondrial function may differ between genotypes. To explore the relationship between hormone deficiency and mitochondria in mice with extended longevity, we evaluated activity, protein, and gene expression of oxidative phosphorylation components in dwarf and wild-type mice at varying ages. Liver complex I + III activity was higher in dwarf mice compared to wild-type mice. The activity of I + III decreased between 3 and 20 months of age in both genotypes with greater declines in wild-type mice in liver and skeletal muscle. Complex IV activities in the kidney were elevated in 3- and 20-month-old dwarf mice relative to wild-type mice. In Ames mice, protein levels of the 39 kDa complex I subunit were elevated at 20 months of age when compared to wild-type mouse mitochondria for every tissue examined. Kidney and liver mitochondria from 20-month-old dwarf mice had elevated levels of both mitochondrially-encoded and nuclear-encoded complex IV proteins compared to wild-type mice (p dwarf mice. Overall, we found that several components of the oxidative phosphorylation (OXPHOS) system were elevated in Ames mice. Mitochondrial to nuclear DNA ratios were not different between genotypes despite the marked increase in PGC-1α levels in dwarf mice. The increased OXPHOS activities, along with lower ROS production in dwarf mice, predict enhanced mitochondrial function and efficiency, two factors likely contributing to long-life in Ames mice.

  9. NASA strategic plan (United States)


    The NASA Strategic Plan is a living document. It provides far-reaching goals and objectives to create stability for NASA's efforts. The Plan presents NASA's top-level strategy: it articulates what NASA does and for whom; it differentiates between ends and means; it states where NASA is going and what NASA intends to do to get there. This Plan is not a budget document, nor does it present priorities for current or future programs. Rather, it establishes a framework for shaping NASA's activities and developing a balanced set of priorities across the Agency. Such priorities will then be reflected in the NASA budget. The document includes vision, mission, and goals; external environment; conceptual framework; strategic enterprises (Mission to Planet Earth, aeronautics, human exploration and development of space, scientific research, space technology, and synergy); strategic functions (transportation to space, space communications, human resources, and physical resources); values and operating principles; implementing strategy; and senior management team concurrence.

  11. NASA systems engineering handbook (United States)

    Shishko, Robert; Aster, Robert; Chamberlain, Robert G.; McDuffee, Patrick; Pieniazek, Les; Rowell, Tom; Bain, Beth; Cox, Renee I.; Mooz, Harold; Polaski, Lou


    This handbook brings the fundamental concepts and techniques of systems engineering to NASA personnel in a way that recognizes the nature of NASA systems and environment. It is intended to accompany formal NASA training courses on systems engineering and project management when appropriate, and is designed to be a top-level overview. The concepts were drawn from NASA field center handbooks, NMI's/NHB's, the work of the NASA-wide Systems Engineering Working Group and the Systems Engineering Process Improvement Task team, several non-NASA textbooks and guides, and material from independent systems engineering courses taught to NASA personnel. Five core chapters cover systems engineering fundamentals, the NASA Project Cycle, management issues in systems engineering, systems analysis and modeling, and specialty engineering integration. It is not intended as a directive.

  12. Three Good Reasons for Celebrating at the ESO/ST-ECF Science Archive Facility (United States)


    Great Demand for Data from New "Virtual Observatory" Summary Due to a happy coincidence, the ESO/ST-ECF Science Archive Facility is celebrating three different milestones at the same time: * its 10th anniversary since the establishment in 1991 * the 10,000th request for data , and * the signing-up of active user number 2000 . This Archive contains over 8 Terabytes (1 Terabyte = 1 million million bytes) of valuable observational data from the NASA/ESA Hubble Space Telescope (HST), the ESO Very Large Telescope (VLT) and other ESO telescopes . Its success paves the way for the establishment of "Virtual Observatories" from which first-class data can be obtained by astronomers all over the world. This greatly enhances the opportunities for more (young) scientists to participate in front-line research. PR Photo 34/00 : Front-page of a new brochure, describing the ESO/ST-ECF Science Archive Facility. Just 10 years ago, on the 1st of January 1991, the ESO/ST-ECF (European Southern Observatory/Space Telescope-European Coordinating Facility) Science Archive Facility opened. It has since served the astronomical community with gigabyte after gigabyte of high-quality astronomical data from some of the world's leading telescopes. The Archive, which is located in Garching, just outside Munich (Germany), contains data from the 2.4-m NASA/ESA Hubble Space Telescope , as well as from several ESO telescopes: the four 8.2-m Unit Telescopes of the Very Large Telescope (VLT) at the Paranal Observatory , and the 3.5-m New Technology Telescope (NTT) , the 3.6-m telescope and the MPG/ESO 2.2-m telescope at La Silla. The Archive is a continuously developing project - in terms of amounts of data stored, the number of users and in particular because of the current dramatic development of innovative techniques for data handling and storage. In the year 2000 more than 2 Terabytes (2000 Gigabytes) of data were distributed to users worldwide. The archiving of VLT data has been described in ESO PR

  13. Accessing Wind Tunnels From NASA's Information Power Grid (United States)

    Becker, Jeff; Biegel, Bryan (Technical Monitor)


    The NASA Ames wind tunnel customers are one of the first users of the Information Power Grid (IPG) storage system at the NASA Advanced Supercomputing Division. We wanted to be able to store their data on the IPG so that it could be accessed remotely in a secure but timely fashion. In addition, incorporation into the IPG allows future use of grid computational resources, e.g., for post-processing of data, or to do side-by-side CFD validation. In this paper, we describe the integration of grid data access mechanisms with the existing DARWIN web-based system that is used to access wind tunnel test data. We also show that the combined system has reasonable performance: wind tunnel data may be retrieved at 50Mbits/s over a 100 base T network connected to the IPG storage server.

  15. RSNA Meeting News: Time for Celebration, Thanksgiving, and Responsibility

    International Nuclear Information System (INIS)

    Lee, Kyung Soo


    From November 25 through 30, 2007, a scientific assembly and annual meeting of the Radiologic Society of North America (RSNA) were held at McCormick Place, Chicago, IL, USA. The RSNA assembly is the largest international medical meeting in the world. Every year, approximately 60,000 people from 80 countries that are radiologists, radiologic technologists, nurses, and people in the vendor companies of radiologic imaging devices or contrast medium gather together to exchange their ideas on radiology, share new techniques of interventional therapeutic procedure, and demonstrate newly-developed radiologic imaging technology. We all Korean radiologists are celebrating these epochmaking events. We achieved much and became prominent internationally as academicians, clinical radiologists, or as radiologic teachers. We owed much to our family, our medical colleagues, our hospitals, and our paramedical colleagues: specifically physicists, radiological technologists and nurses, who helped us to study hard and write good abstracts. We cannot thank them more. I am not worried about which place we will rank in the next year in terms of abstract number accepted for presentation. Can we maintain our achievement (let's say the fourth place) continually? Without further earnest and endeavor, we might not maintain the credit that we now achieved. Nothing is permanent because other countries will do their best to overtake the higher places regarding abstract numbers accepted by the RSNA. I also would like to urge all presenters to submit their papers to the Radiology, Radiographics, or other related journals to refine their abstracts into masterpiece articles

    CERN Multimedia

    CERN Bulletin


    A Chinese proverb says that happiness is when friends coming from far and away meet and talk to each other. These wise words could very well be used to sum up the celebrations in honour of the 80th birthdays of Magda and Torleif Ericson, a couple in the normal sense of the word and often also in the field of physics. Torleif joined CERN's Theory Division in 1960, initially to work at the intersection of nuclear and particle physics at the Synchrocyclotron, and retired in 1995.   During the celebratory event on 17 September, speakers reviewed the depth and breadth of the contributions which both Torleif and Magda have made to theoretical physics in general and to nuclear physics in particular. José Bernabeu, Guy Chanfray, Wolfram Wiese, Achim Richter and Anthony Thomas all covered the considerable research that has been stimulated by the Ericson-Ericson correlation(s) over the past 50 years. A concert by the violinist Jean-Philippe Audoli and the pianist Blandine Eynaud and an informal...

  17. Advances in natural deduction a celebration of Dag Prawitz's work

    CERN Document Server

    Haeusler, Edward; Paiva, Valeria


    This collection of papers celebrating the contributions of Swedish logician Dag Prawitz to Proof Theory, has been assembled from those presented at the Natural Deduction conference organized in Rio de Janeiro to honour his  seminal  research. Dag Prawitz’s work forms the basis of intuitionistic type theory and his inversion principle constitutes the foundation of most modern accounts of proof-theoretic semantics in Logic, Linguistics and  Theoretical Computer Science. The range of contributions includes material on the extension of natural deduction with higher-order rules, as opposed to higher-order connectives, and a paper discussing the application of natural deduction rules to dealing with equality in predicate calculus. The volume continues with a key chapter summarizing work on the extension of the Curry-Howard isomorphism (itself a by-product of the work on natural deduction), via methods of category theory that have been successfully applied to linear logic, as well as many other contributions fr...

    Today the European Southern Observatory is celebrating its 50th anniversary. This article retraces the story of one of Europe's greatest laboratories, which came into being with CERN's support and assistance.   La Silla, June 1968. The three telescopes in the background are (from left to right): the Grand Prism Objectif (GPO, first light in 1968), the ESO 1 metre telescope (1966), and the ESO 1.5 metre telescope (1968). They have been decommissioned. The white dome closest to the viewer is the ESO 1 metre Schmidt telescope, which began work in 1971. Image: ESO/E. Maurice. In the spring of 1953, in Leiden in the Netherlands, a group of astronomers including Walter Baade, Jan Oort, Adriaan Blaauw, Otto Heckmann and Jan Bannier (who was then President of CERN's Provisional Council) for the first time discussed the possibility of founding a European space observatory. The objective was to build it in the southern hemisphere where there were very few observatories with pow...

  19. Celebrity disclosures and information seeking: the case of Angelina Jolie. (United States)

    Juthe, Robin H; Zaharchuk, Amber; Wang, Catharine


    On 14 May 2013, actress Angelina Jolie disclosed that she had a BRCA1 mutation and underwent a prophylactic bilateral mastectomy. This study documents the impact of her disclosure on information-seeking behavior, specifically that regarding online genetics and risk reduction resources available from the National Cancer Institute. Using Adobe Analytics, daily page views for 11 resources were tracked from 23 April 2013 through 25 June 2013. Usage data were also obtained for four resources over a 2-year period (2012-2013). Source of referral that viewers used to locate a specific resource was also examined. There was a dramatic and immediate increase in traffic to the National Cancer Institute's online resources. The Preventive Mastectomy fact sheet received 69,225 page views on May 14, representing a 795-fold increase as compared with the previous Tuesday. A fivefold increase in page views was observed for the PDQ Genetics of Breast and Ovarian Cancer summary in the same time frame. A substantial increase, from 0 to 49%, was seen in referrals from news outlets to four resources from 7 May to 14 May. Celebrity disclosures can dramatically influence online information-seeking behaviors. Efforts to capitalize on these disclosures to ensure easy access to accurate information are warranted.

  20. The sport celebrity endorsement in promotion of products and services

    Dugalić Sretenka


    Full Text Available Celebrity endorsement which includes promotion with engagement of famous athlete is different from other promotional campaigns; the only similarity is in a strong, effective way that defines purchase. The purpose of this paper is to explain how achievements in sports (tennis influence the formation of opinions, attitudes, and habits of individuals. The work is of theoretical and empirical character and consists of three parts. The first part explains theoretical aspects; and in the second part of the methodology necessary for process analysis and obtaining research results that may have practical application in marketing through the transformation of sports results in tangible value. The third part sublimated research results as the basis for discussions and presentation of the conclusions that have been reached in the study. Case studies refer to sports, athletes, tennis players, as well as the creators of the sports experience, and their impact on the target groups that can be commercially exploited. In particular, it explored the impact of individual characteristics of Fame players via variable: experience, intelligence, professionalism and other personal qualities, as well as engagement and activities outside the scope of professional tennis.

    Katarina Anthony


    Last week, former and current computing operations staff, managers and system engineers were reunited at CERN. They came together to celebrate a milestone not only for the IT Department but also for CERN: the 50th anniversary of the CERN Operations group and the 40th birthday of the Computer Centre.   The reunion was organised by former chief operator, Pierre Bénassi, and took place from 26 to 27 April. Among the 44 attendees were Neil Spoonley and Charles Symons, who together created the Operations group back in 1963. “At that time, working in the Operations group was a very physical job,” recalls former Operations Group Leader, David Underhill. “For that reason, many of the first operators were former firemen.” A few of the participants enjoyed a tour of CERN landmarks during their visit (see photo). The group toured the CERN Computing Centre (accompanied by IT Department Head, Frédéric Hemmer), as well as the ATLAS cav...

  2. Consumerism, Celebrity Culture and the Aesthetic Impure in Oscar Wilde

    Directory of Open Access Journals (Sweden)

    Martino, Pierpaolo


    Full Text Available This article investigates the discursive arena in which Oscar Wilde exercised his countercultural and necessarily impure aesthetic taste, focusing on some defining aspects and texts of Wilde's epopee, namely his cult of celebrity, which was nourished, in particular, by his 1882 tour of the United States, his interest in performance – which turned the author into the director and main actor of the very drama entitled Oscar Wilde – and his apparently contradictory approach to consumer culture. Wilde, indeed, seemed to embrace opposite stances in relation to consumerism as it is witnessed by such works as «The Soul of Man Under Socialism» and The Picture of Dorian Gray, on the one side, and «The Decay of Lying», Lady Windermere's Fan and An Ideal Husband, on the other. This essay also reads Wilde's last play The Importance of Being Earnest in terms of a «performance about performance», rooted as Wilde's previous plays in consumer culture and capable of deconstructing the Victorian highly normative (and 'rational' approach to gender and, in particular, to masculinity.

  8. The Public, the Press, and Celebrities in The Return of Sherlock Holmes

    Directory of Open Access Journals (Sweden)

    Thomas Vranken


    Full Text Available Arthur Conan Doyle and his consulting detective had been famous for more than ten years when Doyle came to write The Return of Sherlock Holmes. In the following essay, I argue that this experience of fame shaped the composition of the third series of Holmes stories, in which the detective is resurrected a decade after going over the Reichenbach Falls. The essay approaches celebrity as a competitive interaction in which the public, the press, and the celebrity vie for control. It is argued that the stories in The Return of Sherlock Holmes work to empower the various celebrities that they portray – including not just Holmes but also well-known aristocrats, statesmen, scholars, and female ‘beauties’ – and to disempower their rival co-participants in the celebrity dynamic: the public and the press.

  10. The hot body issue: Weight and caption tone in celebrity gossip magazines. (United States)

    McDonnell, Andrea; Lin, Linda


    While representations of bodies and weight have been studied in regards to fashion and fitness magazines, little research exists that examines such representations in celebrity gossip magazines. Using data collected through content analysis of 262 photo-caption units published in June 2015 issues of American celebrity gossip magazines, this study examines representations of bodies within the genre and the relationship between the gender, race, and body size of pictured celebrities and the tone of accompanying captions. Results indicate that celebrity gossip magazines critique the bodies of both female and male subjects, but that women are more likely to be the subject of negative comments than men. Underweight women and overweight men are especially targeted for criticism. Latinos are praised more often than other racial groups. The implications of these representations are discussed.

    Full Text Available PURPOSE: Suicide is a major health problem in Korea. Extensive media exposure of celebrity suicide may induce imitative suicide, a phenomenon called the Werther effect. We examined the increased suicide risk following the suicides of an entertainer and a politician, and identified the relative suicide risks. METHODS: News articles about the celebrity suicides were obtained from three major newspapers and analysed for quantitative and qualitative features. Imitative suicide risk was investigated by applying a Poisson time series autoregression model with suicide mortality data from the National Statistics Office for 1.5 years before and 1.5 years after each celebrity's suicide. The period with a significantly increased number of suicides immediately after the celebrity's suicide determined the Werther effect band. The relative risk during this period was examined for different ages, genders, and suicide methods. RESULTS: News reports were more numerous and they contained more positive definitions about the entertainer's suicide. The risk of suicide deaths rose markedly after both celebrity suicides. However, the Werther effect band was longer for the entertainer (6 weeks than for the politician (4 weeks. The relative suicide risk was significant for almost all ages and both genders during that of both individuals. Use of the same suicide method was a prominent risk factor after both celebrity suicides. CONCLUSIONS: Our results confirm the existence of imitative suicide behaviours, suggesting a facilitation effect of media reports. Guidelines for responsible media reporting need to be implemented to enhance public mental health in Korea.

  14. Endothelial function and vascular oxidative stress in long-lived GH/IGF-deficient Ames dwarf mice. (United States)

    Csiszar, Anna; Labinskyy, Nazar; Perez, Viviana; Recchia, Fabio A; Podlutsky, Andrej; Mukhopadhyay, Partha; Losonczy, Gyorgy; Pacher, Pal; Austad, Steven N; Bartke, Andrzej; Ungvari, Zoltan


    Hypopituitary Ames dwarf mice have low circulating growth hormone (GH)/IGF-I levels, and they have extended longevity and exhibit many symptoms of delayed aging. To elucidate the vascular consequences of Ames dwarfism we compared endothelial O2(-) and H2O2 production, mitochondrial reactive oxygen species (ROS) generation, expression of antioxidant enzymes, and nitric oxide (NO) production in aortas of Ames dwarf and wild-type control mice. In Ames dwarf aortas endothelial O2(-) and H2O2 production and ROS generation by mitochondria were enhanced compared with those in vessels of wild-type mice. In Ames dwarf aortas there was a less abundant expression of Mn-SOD, Cu,Zn-SOD, glutathione peroxidase (GPx)-1, and endothelial nitric oxide synthase (eNOS). NO production and acetylcholine-induced relaxation were also decreased in aortas of Ames dwarf mice. In cultured wild-type mouse aortas and in human coronary arterial endothelial cells treatment with GH and IGF significantly reduced cellular O2(-) and H2O2 production and ROS generation by mitochondria and upregulated expression of Mn-SOD, Cu,Zn-SOD, GPx-1, and eNOS. Thus GH and IGF-I promote antioxidant phenotypic changes in the endothelial cells, whereas Ames dwarfism leads to vascular oxidative stress.

  15. A non-randomized [corrected] controlled trial of the active music engagement (AME) intervention on children with cancer. (United States)

    Robb, Sheri L; Clair, Alicia A; Watanabe, Masayo; Monahan, Patrick O; Azzouz, Faouzi; Stouffer, Janice W; Ebberts, Allison; Darsie, Emily; Whitmer, Courtney; Walker, Joey; Nelson, Kirsten; Hanson-Abromeit, Deanna; Lane, Deforia; Hannan, Ann


    Coping theorists argue that environmental factors affect how children perceive and respond to stressful events such as cancer. However, few studies have investigated how particular interventions can change coping behaviors. The active music engagement (AME) intervention was designed to counter stressful qualities of the in-patient hospital environment by introducing three forms of environmental support. The purpose of this multi-site randomized controlled trial was to determine the efficacy of the AME intervention on three coping-related behaviors (i.e. positive facial affect, active engagement, and initiation). Eighty-three participants, ages 4-7, were randomly assigned to one of three conditions: AME (n = 27), music listening (ML; n = 28), or audio storybooks (ASB; n = 28). Conditions were videotaped to facilitate behavioral data collection using time-sampling procedures. After adjusting for baseline differences, repeated measure analyses indicated that AME participants had a significantly higher frequency of coping-related behaviors compared with ML or ASB. Positive facial affect and active engagement were significantly higher during AME compared with ML and ASB (p<0.0001). Initiation was significantly higher during AME than ASB (p<0.05). This study supports the use of the AME intervention to encourage coping-related behaviors in hospitalized children aged 4-7 receiving cancer treatment. (c) 2007 John Wiley & Sons, Ltd.

  16. Use of the modified Ames test as an indicator of the carcinogenicity of residual aromatic extracts

    Energy Technology Data Exchange (ETDEWEB)

    Boogaard, P.; Hedelin, A.; Riley, A.; Rushton, E.; Vaissiere, M.; Minsavage, G.; Rohde, A.; Dalbey, W.


    Existing data demonstrate that residual aromatic extracts (RAEs) can be either carcinogenic or non-carcinogenic. CONCAWE had previously concluded that 'Although limited data available indicate that some RAEs are weakly carcinogenic, it is not possible to provide a general recommendation. Classify on a case-by-case basis' (CONCAWE 2005). Therefore CONCAWE's Health/Toxicology Subgroup (H/TSG) has developed a proposal for the use of the modified Ames test as a short-term predictive screening tool for decisions on the classification of RAEs for carcinogenicity. The relationship between RAE chemistry and carcinogenic potential is not as well understood as it is for some other categories of substances, e.g. Other Lubricant Base Oils (OLBO). However, a correlation has been found between the results of the skin carcinogenicity bioassay and the mutagenicity index (MI) obtained from the modified Ames test. Data supporting this correlation are summarised in this report. The H/TSG confirmed that the modified Ames test can be used as a predictive screening tool and that a cut-off value can be established to make a distinction between carcinogenic and non-carcinogenic products. RAEs with a MI > 0.4 demonstrated carcinogenic potential upon dermal application to mouse skin with chronic exposure. RAEs with a MI > 0.4 did not demonstrate a carcinogenic potential. To justify the use of the modified Ames test with RAEs, additional analysis of the repeatability of the test with RAEs was required. With this objective, CONCAWE sponsored a round robin study with different samples of RAEs from member companies, at three different laboratories. The repeatability demonstrated in the round robin study with RAEs support the proposed use of the modified Ames test. As part of the tools available for use by member companies, the H/TSG proposed a standard operating procedure (SOP) (included as an Appendix to this report) on the conduct of the modified Ames test with RAEs. The H

  17. The Impact of Celebrity Suicide on Subsequent Suicide Rates in the General Population of Korea from 1990 to 2010. (United States)

    Park, Juhyun; Choi, Nari; Kim, Seog Ju; Kim, Soohyun; An, Hyonggin; Lee, Heon-Jeong; Lee, Yu Jin


    The association between celebrity suicide and subsequent increase in suicide rates among the general population has been suggested. Previous studies primarily focused on celebrity suicides in the 2000s. To better understand the association, this study examined the impacts of celebrity suicides on subsequent suicide rates using the data of Korean celebrity suicides between 1990 and 2010. Nine celebrity suicides were selected by an investigation of media reports of suicide deaths published in three major newspapers in Korea between 1990 and 2010. Suicide mortality data were obtained from the National Statistical Office of Korea. Seasonal autoregressive integrated moving average models with intervention analysis were used to test the impacts of celebrity suicides, controlling for seasonality. Six of the 9 celebrity suicides had significant impacts on suicide rates both in the total population and in the same gender- or the same age-subgroups. The incident that occurred in the 1990s had no significant impact on the overall suicide rates, whereas the majority of the incidents in the 2000s had significant influences for 30 or 60 days following each incident. The influence of celebrity suicide was shown to reach its peak following the suicide death of a renowned actress in 2008. The findings may suggest a link between media coverage and the impact of celebrity suicide. Future studies should focus more on the underlying processes and confounding factors that may contribute to the impact of celebrity suicide on subsequent suicide rates.

  18. Internal NASA Study: NASAs Protoflight Research Initiative (United States)

    Coan, Mary R.; Hirshorn, Steven R.; Moreland, Robert


    The NASA Protoflight Research Initiative is an internal NASA study conducted within the Office of the Chief Engineer to better understand the use of Protoflight within NASA. Extensive literature reviews and interviews with key NASA members with experience in both robotic and human spaceflight missions has resulted in three main conclusions and two observations. The first conclusion is that NASA's Protoflight method is not considered to be "prescriptive." The current policies and guidance allows each Program/Project to tailor the Protoflight approach to better meet their needs, goals and objectives. Second, Risk Management plays a key role in implementation of the Protoflight approach. Any deviations from full qualification will be based on the level of acceptable risk with guidance found in NPR 8705.4. Finally, over the past decade (2004 - 2014) only 6% of NASA's Protoflight missions and 6% of NASA's Full qualification missions experienced a publicly disclosed mission failure. In other words, the data indicates that the Protoflight approach, in and of it itself, does not increase the mission risk of in-flight failure. The first observation is that it would be beneficial to document the decision making process on the implementation and use of Protoflight. The second observation is that If a Project/Program chooses to use the Protoflight approach with relevant heritage, it is extremely important that the Program/Project Manager ensures that the current project's requirements falls within the heritage design, component, instrument and/or subsystem's requirements for both the planned and operational use, and that the documentation of the relevant heritage is comprehensive, sufficient and the decision well documented. To further benefit/inform this study, a recommendation to perform a deep dive into 30 missions with accessible data on their testing/verification methodology and decision process to research the differences between Protoflight and Full Qualification

    The Ames Laboratory has historically supported the U.S. Department of Energy (USDOE) and its predecessor agencies by providing research into the purification and manufacturing of high purity uranium, thorium, and yttrium metals. Much of this work was accomplished in the late 1950s and early 1960s prior to the legislation of strict rules and regulations covering the disposal of radioactive and chemical wastes. As a result, approximately 800 cubic meters of low-level radioactive wastes, chemical wastes, and contaminated debris were disposed in nine near surface cells located in a 0.75 hectare plot of land owned by Iowa State University in Ames, Iowa. Under a national contract with the U.S. Army Corps of Engineers (USACE), OHM Remediation Services Corp (OHM) was tasked with providing turnkey environmental services to remove, process, package, transport, and coordinate the disposal of the waste materials and contaminated environmental media

    To probe the connection between longevity and stress resistance, we compared the sensitivity of Ames long-lived dwarf mice and control littermates with paraquat, diquat, and dobutamine. In young adult animals, 95% of male and 39% of female controls died after paraquat administration, but no dwarf animals died. When the experiment was repeated at an older age or a higher dosage of paraquat, dwarf mice still showed greater resistance. Dwarf mice also were more resistant to diquat; 80% of male and 60% of female controls died compared with 40% and 20% of dwarf mice, despite greater sensitivity of dwarf liver to diquat. Dwarf mice were also less sensitive to dobutamine-induced cardiac stress and had lower levels of liver and lung F(2)-isoprostanes. This is the first direct in vivo evidence that long-lived Ames dwarf mice have enhanced resistance to chemical insult, particularly oxidative stressors.

    Antimutagenesis against N-nitroso compounds contribute to prevention of human cancer. We have found that Glycyrrhiza aspera ethanolic extract exhibits antimutagenic activity against N-methyl-N-nitrosourea (MNU) using the Ames assay with Salmonella typhimurium TA1535. In the present study, eight purified components from Glycyrrhiza, namely glabridin, glycyrrhetinic acid, glycyrrhizin, licochalcone A, licoricesaponin H2, licoricesaponin G2, liquiritigenin and liquiritin were evaluated for their antimutagenicity against MNU in the Ames assay with S. typhimurium TA1535. Glycyrrhetinic acid, glycyrrhizin, licoricesaponin G2, licoricesaponin H2 and liquiritin did not show the antimutagenicity against MNU in S. typhimurium TA1535. Glabridin, licochalcone A and liquiritigenin reduced revertant colonies derived from MNU in S. typhimurium TA1535 without showing cytotoxic effects, indicating that these compounds possess antimutagenic activity against MNU. The inhibitory activity of glabridin and licochalcone A was more effective than that of liquiritigenin. Thus, Glycyrrhiza contains antimutagenic components against DNA alkylating, direct-acting carcinogens.

    The Ames Laboratory has historically supported the US Department of Energy (USDOE) and its predecessor agencies by providing research into the purification and manufacturing of high purity uranium, thorium, and yttrium metals. Much of this work was accomplished in the late 1950s and early 1960s prior to the legislation of strict rules and regulations covering the disposal of radioactive and chemical wastes. As a result, approximately 800 cubic meters of low-level radioactive wastes, mixed wastes, and contaminated debris were disposed in nine near surface cells located in a 0.75 hectare plot of land owned by Iowa State University in Ames, Iowa. Under a national contract with the US Army Corps of Engineers (USACE), OHM Remediation Services Corp.

    Severe sepsis and septic shock are major causes of morbidity and mortality in patients entering the emergency department (ED) or intensive care unit (ICU). Despite substantial efforts to improve patient outcome, treatment of sepsis remains challenging to clinicians. In this context, early goal directed therapy (EGDT) represents an important concept emphasizing both early recognition of sepsis and prompt initiation of a structured treatment algorithm. As part of the AME evidence series on seps...

  5. 2-Hydroxypyridine-N-oxide (HOPO): Equivocal in the ames assay. (United States)

    Dobo, Krista L; Cheung, Jennifer R; Gunther, William C; Kenyon, Michelle O


    2-Hydroxypyridine-N-oxide (HOPO) is a useful coupling reagent for synthesis of active pharmaceutical ingredients. It has been reported to be weakly mutagenic in the Ames assay (Ding W et al. []: J Chromatogr A 1386:47-52). According to the ICH M7 guidance (2014) regarding control of mutagenic impurities to limit potential carcinogenic risk, mutagens require control in drug substances such that exposure not exceeds the threshold of toxicological concern. Given the weak response observed in the Ames assay and the lack of any obvious structural features that could confer DNA reactivity we were interested to determine if the results were reproducible and investigate the role of potentially confounding experimental parameters. Specifically, Ames tests were conducted to assess the influence of compound purity, solvent choice, dose spacing, toxicity, type of S9 (aroclor vs phenobarbital/β-napthoflavone), and lot variability on the frequency of HOPO induced revertant colonies. Initial extensive testing using one lot of HOPO produced no evidence of mutagenic potential in the Ames assays. Subsequent studies with four additional lots produced conflicting results, with an ∼2.0-fold increase in revertant colonies observed. Given the rigor of the current investigation, lack of reproducibility between lots, and the weak increase in revertants, it is concluded that HOPO is equivocal in the bacterial reverse mutation assay. It is highly unlikely that HOPO poses a mutagenic risk in vivo; therefore, when it is used as a reagent in pharmaceutical synthesis, it should not be regarded as a mutagenic impurity, but rather a normal process related impurity.

    Full Text Available Background: Highly industrialized Upper Silesia Region is particularly polluted by both anthropogenic and natural airborne particulate matters, which may lead to negative health effects in human. Materials and methods: The aim of the study was to assess the mutagenic properties of dust extracts which were collected in six cities in the Silesian Voivodeship. Dust samples were collected on glass fiber filters by the aspirator with air flow ca. 1 m3/min. Extraction of pollution was carried out using dichlorometane. The extracted samples were dissolved in dimethylsulfoxide (DMSO. The mutagenic properties were assessed using microplate Ames assay MPFTM with the use of bacteria Salmonella typhimurium strain TA98 and TA100. Results: In microplate Ames assay MPFTM there was observed a linear dose-response relationship in both metabolic variants of TA98 strain. Similar relationship was observed for TA100 strain with metabolic activation (S9. Mutagenic activity (AM of 100% extracts for TA98 strain in both metabolic variants (S9 exceeded 2, what indicate highly mutagenic effects of dust extracts. There was no mutagenic activity observed in the assay with TA100 (S9, AM 1. In the variant with exogenous metabolic activation (S9 in TA100 strain AM values ranged from AM1,160,15 to AM9,671,02. Mutagenic activity varied between different cities. Conclusions: The study demonstrated that microplate Ames assay MPFTM is fast and complex method of assessing the mutagenic properties of dust pollution, which exert toxic effect on organisms. The use of microplate Ames assay MPFTM together with chemical analyses of air dust pollution may evaluate the level of exposure in the environment and enable to perform health risk assessment in populations exposed to mutagenic, toxic and cytotoxic substances.

  7. Celebrity endorsements versus created spokespersons in advertising: a survey among students

    Directory of Open Access Journals (Sweden)

    Delarey Van der Waldt


    Full Text Available In this study the use of endorsements in advertising was investigated.  Endorsements can either be in the form of a celebrity acting as a spokesperson for an organisation or the organisation can create a spokesperson to act as an endorser.  The problem that faces marketers is that little scientific proof exists if students perceive celebrity endorsements and creative spokespersons differently with regard to their expertise and trustworthiness.  The aim of this study was to determine the attitudes of respondents with regard to expertise, trustworthiness and attractiveness of created spokesperson and celebrity endorsements in advertisements. This knowledge will provide marketing professionals with the strategic advantage of how and when to make use of an endorser. Ohanian’s (1990 measurement scale of perceived expertise, trustworthiness and attractiveness was adopted in a self-administrative questionnaire for this article.  Respondents (n=185 were exposed to six visual images of endorsers namely:  three celebrities and three created spokespersons.  It was found that attractiveness should not be used as a factor when comparing created endorsers with celebrity endorsers.  The respondents perceived both endorsement applications as highly credible and professionals need to consider each application’s advantages and disadvantages when deciding which application will be more effective for their advertising strategy.  In the long term the organisation might find it more cost effective to create its own spokesperson due to the risk of possible characteristics changes or negative associations of celebrity endorsers.  Revoking advertisements after celebrity endorsers have received negative publicity or changed character can lead to great financial losses.  Created endorsers, on the other hand, provide the organisation with greater control and the ability to change to adapt to the organisations market and advertising needs.

  11. Mars Rover Model Celebration: Using Planetary Exploration To Enrich STEM Teaching In Elementary And Middle School (United States)

    Bering, E. A.; Ramsey, J.; Dominey, W.; Kapral, A.; Carlson, C.; Konstantinidis, I.; James, J.; Sweaney, S.; Mendez, R.


    The present aerospace engineering and science workforce is ageing. It is not clear that the US education system will produce enough qualified replacements to meet the need in the near future. Unfortunately, by the time many students get to high school, it is often too late to get them pointed toward an engineering or science career. Since some college programs require 6 units of high school mathematics for admission, students need to begin consciously preparing for a science or engineering curriculum as early as 6th or 7th grade. The challenge for educators is to convince elementary school students that science and engineering are both exciting, relevant and accessible career paths. The recent NASA Mars Rover missions capture the imagination of children, as NASA missions have done for decades. The University of Houston is in the process of developing a prototype of a flexible program that offers children an in-depth educational experience culminating in the design and construction of their own model rover. The existing prototype program is called the Mars Rover Model Celebration. It focuses on students, teachers and parents in grades 3-8. Students will design and build a model of a Mars rover to carry out a student selected science mission on the surface of Mars. The model will be a mock-up, constructed at a minimal cost from art supplies. The students will build the models as part of a project on Mars. The students will be given design criteria for a rover and will do basic research on Mars that will determine the objectives and features of their rover. This project may be used either informally as an after school club or youth group activity or formally as part of a class studying general science, earth science, solar system astronomy or robotics, or as a multi-disciplinary unit for a gifted and talented program. The program culminates in a capstone event held at the University of Houston (or other central location in the other communities that will be involved

  12. Selling safety: the use of celebrities in improving awareness of safety in commercial aviation. (United States)

    Molesworth, Brett R C; Seneviratne, Dimuth; Burgess, Marion


    The aim of this study was to investigate the influential power of a celebrity to convey key safety messages in commercial aviation using a pre-flight safety briefing video. In addition, the present research sought to examine the effectiveness of subtitles in aiding the recall of these important messages as well as how in-cabin aircraft noise affects recall of this information. A total of 101 participants were randomly divided into four groups (no noise without subtitles, no noise with subtitles, noise without subtitles and noise with subtitles) and following exposure to a pre-recorded pre-flight safety briefing video were tested for recall of key safety messages within that video. Participants who recognised and recalled the name of the celebrity in the safety briefing video recalled significantly more of the messages than participants who did not recognise the celebrity. Subtitles were also found to be effective, however, only in the presence of representative in-cabin aircraft noise. Practitioner Summary: Passenger attention to pre-flight safety briefings on commercial aircraft is poor. Utilising the celebrity status of a famous person may overcome this problem. Results suggest that celebrities do increase the recall of safety-related information.

  13. NASA Technology Plan 1998 (United States)


    This NASA Strategic Plan describes an ambitious, exciting vision for the Agency across all its Strategic Enterprises that addresses a series of fundamental questions of science and research. This vision is so challenging that it literally depends on the success of an aggressive, cutting-edge advanced technology development program. The objective of this plan is to describe the NASA-wide technology program in a manner that provides not only the content of ongoing and planned activities, but also the rationale and justification for these activities in the context of NASA's future needs. The scope of this plan is Agencywide, and it includes technology investments to support all major space and aeronautics program areas, but particular emphasis is placed on longer term strategic technology efforts that will have broad impact across the spectrum of NASA activities and perhaps beyond. Our goal is to broaden the understanding of NASA technology programs and to encourage greater participation from outside the Agency. By relating technology goals to anticipated mission needs, we hope to stimulate additional innovative approaches to technology challenges and promote more cooperative programs with partners outside NASA who share common goals. We also believe that this will increase the transfer of NASA-sponsored technology into nonaerospace applications, resulting in an even greater return on the investment in NASA.

  15. Full-Span Tiltrotor Aeroacoustic Model (TRAM) Overview and 40- by 80-Foot Wind Tunnel Test. [conducted in the 40- by 80-Foot Wind Tunnel at Ames Research Center (United States)

    McCluer, Megan S.; Johnson, Jeffrey L.; Rutkowski, Michael (Technical Monitor)


    Most helicopter data trends cannot be extrapolated to tiltrotors because blade geometry and aerodynamic behavior, as well as rotor and fuselage interactions, are significantly different for tiltrotors. A tiltrotor model has been developed to investigate the aeromechanics of tiltrotors, to develop a comprehensive database for validating tiltrotor analyses, and to provide a research platform for supporting future tiltrotor designs. The Full-Span Tiltrotor Aeroacoustic Model (FS TRAM) is a dual-rotor, powered aircraft model with extensive instrumentation for measurement of structural and aerodynamic loads. This paper will present the Full-Span TRAM test capabilities and the first set of data obtained during a 40- by 80-Foot Wind Tunnel test conducted in late 2000 at NASA Ames Research Center. The Full-Span TRAM is a quarter-scale representation of the V-22 Osprey aircraft, and a heavily instrumented NASA and U.S. Army wind tunnel test stand. Rotor structural loads are monitored and recorded for safety-of-flight and for information on blade loads and dynamics. Left and right rotor balance and fuselage balance loads are monitored for safety-of-flight and for measurement of vehicle and rotor aerodynamic performance. Static pressure taps on the left wing are used to determine rotor/wing interactional effects and rotor blade dynamic pressures measure blade airloads. All of these measurement capabilities make the FS TRAM test stand a unique and valuable asset for validation of computational codes and to aid in future tiltrotor designs. The Full-Span TRAM was tested in the NASA Ames Research Center 40- by 80-Foot Wind Tunnel from October through December 2000. Rotor and vehicle performance measurements were acquired in addition to wing pressures, rotor acoustics, and Laser Light Sheet (LLS) flow visualization data. Hover, forward flight, and airframe (rotors off) aerodynamic runs were performed. Helicopter-mode data were acquired during angle of attack and thrust sweeps for

  16. Celebrities' Memorial Afterlives: Obituaries, Tributes, and Posthumous Gossip in the Romanian Media Deathscape. (United States)

    Rusu, Mihai S


    Cross-culturally, dead are protected from posthumous negative evaluations by the universal "nil nisi bonum" precept that governs the ethics within the community of mourners. In this study, we set out to test the observance of this injunction against posthumous gossiping in the Romanian public deathscape. Obituaries and other posthumous articles ( N = 1,148) were collected that covered the deaths of 63 celebrities who passed away between 2013 and 2016. Materials were gathered from the digital archives of three Romanian news sources (a news agency, a "quality" newspaper, and a tabloid), published one week after the moment of death. The findings show that 22% of the articles do contain negative evaluations of the deceased. The percentage rises to 36.4% if we restrict the sample to only those celebrities with a controversial anthumous reputation (19 of 63). These results indicate that celebrities are not spared from critical assessments after they pass away.

  17. Sports celebrities and public health: Diego Maradona's influence on drug use prevention. (United States)

    Brown, William J; de Matviuk, Marcela Alejandra Chavan


    Exposure to a sports celebrity through media and sporting events can have important influences on a public health issue associated with that celebrity. The battle against drug use by Argentinean soccer icon Diego Maradona has provoked concerns about drug abuse and prevention in Argentina, particularly among young people. The present study analyzes how two forms of involvement with Maradona affected the public's concern and perceptions of drug use after Maradona's drug-related health crisis in 2004. Results indicate that those who had a greater degree of parasocial interaction with Maradona were more likely to have an increased awareness of drug abuse, a greater personal concern about drug abuse, abstained from drug use, and more strongly support drug abuse prevention programs. In contrast, identification with Maradona had a mitigating effect on drug use prevention. Implications of these findings regarding the influence of sports celebrities on substance abuse are discussed.

  18. The laureate as celebrity genius: How Scientific American's John Horgan profiled Nobel Prize winners. (United States)

    Fahy, Declan


    When scientists become Nobel laureates, they become famous in science and public life, but few studies have examined the nature of their scientific celebrity. This article examines how Scientific American portrayed laureates in order to identify and explain core features of Nobel fame. It examines the portrayals of seven laureates - Francis Crick, Linus Pauling, Hans Bethe, Murray Gell-Mann, Brian Josephson, Philip Anderson and Subrahmanyan Chandrasekhar - in magazine profiles written between 1992 and 1995 by science writer John Horgan. Its textual analysis finds the scientists are portrayed as combining the sociological characteristics of genius, including enormous productivity and lasting impact, with the representational characteristics of celebrities, such as the merging of public and private lives. Their form of scientific celebrity is grounded in their field-changing research, which is presented as a product of their idiosyncratic personalities. Nobel science is presented as knowledge created by an ultra-elite of exceptional individuals.

The project's unique strength lies in engaging students in the process of spacecraft design and interesting them in aerospace engineering careers. The project is aimed at elementary and secondary education. Not only will these students learn about scientific fields relevant to the mission (space science, physics, geology, robotics, and more), they will gain an appreciation for how this knowledge is used to tackle complex problems. The low cost of the event makes it an ideal enrichment vehicle for low income schools. It provides activities that provide professional development to educators, curricular support resources using NASA Science Mission Directorate (SMD) content, and provides family opportunities for involvement in K-12 student learning. This paper will describe the development of a detailed set of new 5E lesson plans to

  20. NASA Airborne Science Program: NASA Stratospheric Platforms (United States)

    Curry, Robert E.


    The National Aeronautics and Space Administration conducts a wide variety of remote sensing projects using several unique aircraft platforms. These vehicles have been selected and modified to provide capabilities that are particularly important for geophysical research, in particular, routine access to very high altitudes, long range, long endurance, precise trajectory control, and the payload capacity to operate multiple, diverse instruments concurrently.

  2. Ames S-32 O-16 O-18 Line List for High-Resolution Experimental IR Analysis (United States)

    Huang, Xinchuan; Schwenke, David W.; Lee, Timothy J.


    By comparing to the most recent experimental data and spectra of the SO2 628 ?1/?3 bands (see Ulenikov et al., JQSRT 168 (2016) 29-39), this study illustrates the reliability and accuracy of the Ames-296K SO2 line list, which is accurate enough to facilitate such high-resolution spectroscopic analysis. The SO2 628 IR line list is computed on a recently improved potential energy surface (PES) refinement, denoted Ames-Pre2, and the published purely ab initio CCSD(T)/aug-cc-pVQZ dipole moment surface. Progress has been made in both energy level convergence and rovibrational quantum number assignments agreeing with laboratory analysis models. The accuracy of the computed 628 energy levels and line list is similar to what has been achieved and reported for SO2 626 and 646, i.e. 0.01-0.03 cm(exp -1) for bands up to 5500 cm(exp -1). During the comparison, we found some discrepancies in addition to overall good agreements. The three-IR-list based feature-by-feature analysis in a 0.25 cm(exp -1) spectral window clearly demonstrates the power of the current Ames line lists with new assignments, correction of some errors, and intensity contributions from varied sources including other isotopologues. We are inclined to attribute part of detected discrepancies to an incomplete experimental analysis and missing intensity in the model. With complete line position, intensity, and rovibrational quantum numbers determined at 296 K, spectroscopic analysis is significantly facilitated especially for a spectral range exhibiting such an unusually high density of lines. The computed 628 rovibrational levels and line list are accurate enough to provide alternatives for the missing bands or suspicious assignments, as well as helpful to identify these isotopologues in various celestial environments. The next step will be to revisit the SO2 828 and 646 spectral analyses.

  3. Feature combination networks for the interpretation of statistical machine learning models: application to Ames mutagenicity. (United States)

    Webb, Samuel J; Hanser, Thierry; Howlin, Brendan; Krause, Paul; Vessey, Jonathan D


    A new algorithm has been developed to enable the interpretation of black box models. The developed algorithm is agnostic to learning algorithm and open to all structural based descriptors such as fragments, keys and hashed fingerprints. The algorithm has provided meaningful interpretation of Ames mutagenicity predictions from both random forest and support vector machine models built on a variety of structural fingerprints.A fragmentation algorithm is utilised to investigate the model's behaviour on specific substructures present in the query. An output is formulated summarising causes of activation and deactivation. The algorithm is able to identify multiple causes of activation or deactivation in addition to identifying localised deactivations where the prediction for the query is active overall. No loss in performance is seen as there is no change in the prediction; the interpretation is produced directly on the model's behaviour for the specific query. Models have been built using multiple learning algorithms including support vector machine and random forest. The models were built on public Ames mutagenicity data and a variety of fingerprint descriptors were used. These models produced a good performance in both internal and external validation with accuracies around 82%. The models were used to evaluate the interpretation algorithm. Interpretation was revealed that links closely with understood mechanisms for Ames mutagenicity. This methodology allows for a greater utilisation of the predictions made by black box models and can expedite further study based on the output for a (quantitative) structure activity model. Additionally the algorithm could be utilised for chemical dataset investigation and knowledge extraction/human SAR development.

    Energy Technology Data Exchange (ETDEWEB)

    Busch, D.B.; Hatcher, J.F.; Bryan, G.T.


    Recovery from urine of the mutagenic activity of 2-anthramine, cyclophosphamide, 7,12-dimethylbenz(a)anthracene, 6-chloro-9-((3-(2-chloroethylamino)-propyl)amino)-2-methoxyacridine dihydrochloride (ICR-191), mitomycin-C, nitrofurantoin, and quercetin was studied with several of the Ames tester strains using acetone-extracted XAD-2 columns with yields ranging from 27% to 79%. Dose responses of the pure chemicals were also studied, and results showed TA 97 to be far more susceptible to quercetin mutagenesis than TA 1537. Reducing pour plate agar volume enhanced mutagenesis.

  17. NASA Water Resources Program (United States)

    Toll, David L.


    With increasing population pressure and water usage coupled with climate variability and change, water issues are being reported by numerous groups as the most critical environmental problems facing us in the 21st century. Competitive uses and the prevalence of river basins and aquifers that extend across boundaries engender political tensions between communities, stakeholders and countries. In addition to the numerous water availability issues, water quality related problems are seriously affecting human health and our environment. The potential crises and conflicts especially arise when water is competed among multiple uses. For example, urban areas, environmental and recreational uses, agriculture, and energy production compete for scarce resources, not only in the Western U.S. but throughout much of the U.S. and also in numerous parts of the world. Mitigating these conflicts and meeting water demands and needs requires using existing water resources more efficiently. The NASA Water Resources Program Element works to use NASA products and technology to address these critical water issues. The primary goal of the Water Resources is to facilitate application of NASA Earth science products as a routine use in integrated water resources management for the sustainable use of water. This also includes the extreme events of drought and floods and the adaptation to the impacts from climate change. NASA satellite and Earth system observations of water and related data provide a huge volume of valuable data in both near-real-time and extended back nearly 50 years about the Earth's land surface conditions such as precipitation, snow, soil moisture, water levels, land cover type, vegetation type, and health. NASA Water Resources Program works closely to use NASA and Earth science data with other U.S. government agencies, universities, and non-profit and private sector organizations both domestically and internationally. The NASA Water Resources Program organizes its

  19. Representations of celebrities' weight and shape during pregnancy and postpartum: a content analysis of three entertainment magazine websites. (United States)

    Gow, Rachel W; Lydecker, Janet A; Lamanna, Jennifer D; Mazzeo, Suzanne E


    Entertainment magazine websites provide a continuous stream of celebrity news accessed by over 13 million unique viewers each month. Celebrities' experiences of pregnancy and new motherhood appear to be popular topics within these media outlets; however, little research has investigated the content of this coverage. In this study, investigators coded articles (N=387) published between August 1, 2007 and August 1, 2008 on three popular entertainment magazine websites. Relatively few articles about celebrities' pregnancies discussed weight (13%) or shape (30%), and an even smaller proportion (6.2%) included any discussion of postpartum body dissatisfaction. This suggests a gap between portrayal of celebrities' pregnancies and postpartum experiences and those of non-celebrity women. This disparity is concerning as it might lead to unrealistic expectations about pregnancy and postpartum for both pregnant readers and a more general audience. This study provides important initial information about the messages these media provide regarding pregnancy-related appearance. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Rios, Joseph; Mulfinger, Daniel; Homola, Jeff; Venkatesan, Priya


    NASA's Unmanned Aircraft Systems Traffic Management research aims to develop policies, procedures, requirements, and other artifacts to inform the implementation of a future system that enables small drones to access the low altitude airspace. In this endeavor, NASA conducted a geographically diverse flight test in conjunction with the FAA's six unmanned aircraft systems Test Sites. A control center at NASA Ames Research Center autonomously managed the airspace for all participants in eight states as they flew operations (both real and simulated). The system allowed for common situational awareness across all stakeholders, kept traffic procedurally separated, offered messages to inform the participants of activity relevant to their operations. Over the 3- hour test, 102 flight operations connected to the central research platform with 17 different vehicle types and 8 distinct software client implementations while seamlessly interacting with simulated traffic.

    Full Text Available Waterpipe smoking has become a global youth trend especially in the Middle East countries and Iran . The aim of this study was to determine the mutagenic effects of three most popular flavored tobaccos by four different salmonella typhimurium strains and compare the possible mutagenic effects of the test samples. Ames mutagenicity assessment was conducted according to the OECD guideline using TA100, TA98 , YG1024 and YG1029 strains. Charcoal burned flavored tobaccos of three different flavors including Orange, Double Apple, and Lime Mint were filtered and exposed to all strains after strain identification tests and MIC ,MBC determinations. The Ames test results indicated significant mutagenic effects of tobacco samples in all four test strains when compared with negative control (p≤0.0001. The highest Mutagenic Factor (MF was seen in Double Apple samples using TA 98 (MF=11.5±3.3 . In all experiments, TA strains showed higher sensitivity to the samples than YG strains which suggest these two strains for further regulatory toxicity tests ,policy making purposes and tobacco control programs . Present results represents an important step in understanding the genotoxic potentials of three most popular flavored tobaccos samples of a famous brand in the global markets .

  2. Low body temperature in long-lived Ames dwarf mice at rest and during stress. (United States)

    Hunter, W S; Croson, W B; Bartke, A; Gentry, M V; Meliska, C J


    Among homeothermic animals, larger species generally have lower metabolic rates and live longer than do smaller species. Because Ames dwarf mice (dwarfs) live approximately 1 year longer than their larger normal sex- and age-matched siblings (normals), we hypothesized that they would have lower body core temperature (Tco). We, therefore, measured Tco of six dwarfs and six normals during 24-h periods of ad lib feeding, 24-h food deprivation, and emotional stress induced by cage switching. With ad lib feeding, Tco of dwarfs averaged 1.6 degrees C lower than normals; during food deprivation, Tco of both dwarfs and controls was significantly lower than when food was available ad lib; and following cage switch, Tco was elevated in both groups. However, during all three experiments, Tco was significantly lower in dwarfs than in normals. These data support the hypothesis that Ames dwarf mice, which live longer than normal size controls, maintain lower Tco than normals. Because dwarfs are deficient in thyroid stimulating hormone (TSH) and growth hormone (GH), their low Tco may be a result of reduced thermogenesis due to lack of those hormones. However, whether low Tco per se is related to the increased longevity of the dwarf mice remains an interesting possibility to be investigated.

  3. Thyroxine modifies the effects of growth hormone in Ames dwarf mice. (United States)

    Do, Andrew; Menon, Vinal; Zhi, Xu; Gesing, Adam; Wiesenborn, Denise S; Spong, Adam; Sun, Liou; Bartke, Andrzej; Masternak, Michal M


    Ames dwarf (df/df) mice lack growth hormone (GH), thyroid stimulating hormone and prolactin. Treatment of juvenile df/df mice with GH alone stimulates somatic growth, reduces insulin sensitivity and shortens lifespan. Early-life treatment with thyroxine (T4) alone produces modest growth stimulation but does not affect longevity. In this study, we examined the effects of treatment of juvenile Ames dwarf mice with a combination of GH + T4 and compared them to the effects of GH alone. Treatment of female and male dwarfs with GH + T4 between the ages of 2 and 8 weeks rescued somatic growth yet did not reduce lifespan to match normal controls, thus contrasting with the previously reported effects of GH alone. While the male dwarf GH + T4 treatment group had no significant effect on lifespan, the female dwarfs undergoing treatment showed a decrease in maximal longevity. Expression of genes related to GH and insulin signaling in the skeletal muscle and white adipose tissue (WAT) of female dwarfs was differentially affected by treatment with GH + T4 vs. GH alone. Differences in the effects of GH + T4 vs. GH alone on insulin target tissues may contribute to the differential effects of these treatments on longevity.

    Lack of data on safety of herbal medicines have endangered human health and life. The present study evaluated the genotoxic and mutagenic effect of Kalanchoe laciniata to access the safety and usefulness of the medicinal plant. Aqua-methanolic and n-hexane extracts of K. laciniata were evaluated for the genotoxic potential using Ames assay and cytotoxicity was evaluated using MTT assay. Ames assay was conducted using two strains of Salmonella typhimurium TA-100 and TA-102 whereas MTT assay was performed on baby hamster kidney cell line BHK-21. Aqua-methanolic extract of K. laciniata exhibited significant mutagenicity when exposed to TA-102 strain with a mutagenic index of 50.66 and 54.74 at maximum dose 150 mg/plate. The extract was also mutagenic to TA-100 strain but to a lesser extent. M.I of n-hexane extract was 12.15 and 15.51 for TA-100 and TA-102 respectively. n-hexane extract was mutagenic but little difference was observed between results of two strains. Both extracts were found to be cytotoxic with an IC 50 of 321.9 and 638.5 µg/mL for aqua-methanolic and n-hexane extracts respectively. On the basis of results it was concluded that aqua-methanolic and n-hexane extracts of K. laciniata possess mutagenic and cytotoxic potential. It is suggested to explore the plant further to evaluate its safety in rodents and other species.

  5. Application of the Ames mutagenicity test to food processed by physical preservation methods

    International Nuclear Information System (INIS)

    Kooij, J.G. van; Leveling, H.B.; Schubert, J.


    An irradiated (380 krad) mixture of four fresh vegetables - leek, celery, carrot, and cauliflower - was examined for mutagenicity by the Ames mutagenicity test using four different histidine-deficient strains of Salmonellae. Water extracts were prepared from the irradiated and unirradiated vegetables - a freeze dried extract (FDE) and a boiled extract (BE). Several problems were overcome in the mutagenicity testing of a complex substance such as food which contains free histidine, different species of bacteria, and a mixture of low and high molecular weight chemicals. In addition, we eliminated an omission in the usual protocols of the Ames test by testing the positive mutagen controls in the presence and absence of the test samples, thus reducing the possible incidence of false negatives and false positives. The induction and expression of mutagenesis by sodium azide (SA) and ethidium bromide (EB) in TA 100 and TA 98 mutant strains, respectively, decreased with increasing amounts of FDE, while increasing levels of BE suppressed the number of revertants in TA 98 in the presence of EB, but exerted little influence on the mutagenicity of SA in TA 100. No difference was observed in the antimutagenic action between the irradiated and unirradiated vegetable extracts. Both the FDE and BE preparations suppressed the action of a frameshift mutagen, but with a base-pair mutagen only the FDE or uncooked vegetable extracts produced suppression. (author)

  6. Are effects of common ragwort in the Ames test caused by pyrrolizidine alkaloids? (United States)

    Bovee, Toine F H; Helsdingen, Richard J R; Hoogenboom, Ron L A P; de Nijs, Monique W C M; Liu, Xiaojie; Vrieling, Klaas; Klinkhamer, Peter G L; Peijnenburg, Ad A C M; Mulder, Patrick P J


    It has previously been demonstrated by others that acetone extracts of Senecio jacobaea (syn. Jacobaea vulgaris, common or tansy ragwort) test positive in the Salmonella/microsome mutagenicity test (Ames test). Pyrrolizidine alkaloids (PAs) are thought to be responsible for these mutagenic effects. However, it was also observed that the major PA present in common ragwort, jacobine, produced a negative response (with and without the addition of rat liver S9) in Salmonella test strains TA98, TA100, TA1535 and TA1537. To investigate which compounds in the plant extracts were responsible for the positive outcome, the present study investigated the contents and mutagenic effects of methanol and acetone extracts prepared from dried ground S. jacobaea and Senecio inaequidens (narrow-leafed ragwort). Subsequently, a fractionation approach was set up in combination with LC-MS/MS analysis of the fractions. It was shown that the positive Ames test outcomes of S. jacobaea extracts are unlikely to be caused by PAs, but rather by the flavonoid quercetin. This study also demonstrates the importance of identifying compounds responsible for positive test results in bioassays. Copyright © 2015 Elsevier B.V. All rights reserved.

  7. Assessment of diphenylcyclopropenone for photochemically induced mutagenicity in the Ames assay

    Energy Technology Data Exchange (ETDEWEB)

    Wilkerson, M.G.; Connor, T.H.; Henkin, J.; Wilkin, J.K.; Matney, T.S.


    The photochemical conversion of diphenylcyclopropenone to diphenylacetylene has recently been reported. Diphenylcyclopropenone is used in the treatment of alopecia areata and is nonmutagenic in a limited Ames assay. We examined diphenylcyclopropenone and diphenylacetylene, as well as synthetic precursors of diphenylcyclopropenone--dibenzylketone and alpha,alpha'-dibromodibenzylketone--for mutagenicity against TA100, TA98, TA102, UTH8413, and UTH8414. All compounds were nonmutagenic except alpha,alpha'-dibromodibenzylketone, which was a potent mutagen in TA100 with and without S-9 activation. The effect of photochemical activation of diphenylcyclopropenone in the presence of bacteria demonstrated mutagenicity in UTH8413 (two times background) at 10 micrograms/plate with S-9 microsomal activation. 8-Methoxypsoralen produces a mutagenic response in TA102 at 0.1 microgram/plate with 60 seconds of exposure to 350 nm light. In vitro photochemically activated Ames assay with S-9 microsomal fraction may enhance the trapping of short-lived photochemically produced high-energy mutagenic intermediates. This technique offers exciting opportunities to trap high-energy intermediates that may play an important role in mutagenesis. This method can be applied to a variety of topically applied dermatologic agents, potentially subjected to photochemical changes in normal use.

    Kim, Jae-Hyun; Park, Eun-Cheol; Nam, Jung-Mo; Park, SoHee; Cho, Jaelim; Kim, Sun-Jung; Choi, Jae-Woo; Cho, Eun


    Purpose Suicide is a major health problem in Korea. Extensive media exposure of celebrity suicide may induce imitative suicide, a phenomenon called the Werther effect. We examined the increased suicide risk following the suicides of an entertainer and a politician, and identified the relative suicide risks. Methods News articles about the celebrity suicides were obtained from three major newspapers and analysed for quantitative and qualitative features. Imitative suicide risk was investigated by applying a Poisson time series autoregression model with suicide mortality data from the National Statistics Office for 1.5 years before and 1.5 years after each celebrity’s suicide. The period with a significantly increased number of suicides immediately after the celebrity’s suicide determined the Werther effect band. The relative risk during this period was examined for different ages, genders, and suicide methods. Results News reports were more numerous and they contained more positive definitions about the entertainer’s suicide. The risk of suicide deaths rose markedly after both celebrity suicides. However, the Werther effect band was longer for the entertainer (6 weeks) than for the politician (4 weeks). The relative suicide risk was significant for almost all ages and both genders during that of both individuals. Use of the same suicide method was a prominent risk factor after both celebrity suicides. Conclusions Our results confirm the existence of imitative suicide behaviours, suggesting a facilitation effect of media reports. Guidelines for responsible media reporting need to be implemented to enhance public mental health in Korea. PMID:24386428

  14. Food choice and overconsumption: effect of a premium sports celebrity endorser. (United States)

    Boyland, Emma J; Harrold, Joanne A; Dovey, Terence M; Allison, Maxine; Dobson, Sarah; Jacobs, Marie-Claire; Halford, Jason C G


    To determine whether exposure to celebrity endorsement in television (TV) food advertising and a nonfood context would affect ad libitum intake of the endorsed product and a perceived alternative brand. A total of 181 children from the UK aged 8-11 years viewed 1 of the following embedded within a cartoon: (1) a commercial for Walker's Crisps (potato chips), featuring a long-standing celebrity endorser; (2) a commercial for a savory food; (3) TV footage of the same endorser in his well-known role as a TV presenter; or (4) a commercial for a nonfood item. Children's ad libitum intake of potato chips labeled "Walker's" and "supermarket brand" was measured using ANOVA. Children who viewed the endorsed commercial or the TV footage of the endorser outside of a food context consumed significantly more of the Walker's chips compared with children in other groups. These children did not reduce their intake of the supermarket brand product to compensate; thus, the endorser effect contributed to overconsumption. The influence of a celebrity endorser on food intake in children extends beyond his or her role in the specific endorsed food commercial, prompting increased consumption of the endorsed brand even when the endorser has been viewed in a nonfood context. Our data suggest that the ubiquitous nature of celebrity media presence may reinforce unhealthy eating practices in children, although research with other endorsers is needed.

  17. Modern China’s Idols: Heroes, Role Models, Stars and Celebrities

    Directory of Open Access Journals (Sweden)

    Elaine M Jeffreys


    Full Text Available This paper examines the diversity of China’s popular culture idols with reference to a commemorative website called ‘The Search for Modern China’, which was launched in late September 2009 to celebrate the sixtieth anniversary of the founding of the People’s Republic of China (PRC under the leadership of the Chinese Communist Party on 1 October 1949. The website’s framing narrative suggests that the history of idol production and celebrity in the PRC can be viewed crudely as marked by disjuncture: the decline of heavy-handed Party-state involvement in the propagandistic manufacturing of socialist idols of production, followed by the grafted-on rise of western-style media-manufactured celebrities as idols of capitalist consumption. However, an analysis of the website’s pantheon of idols reveals that while some idols from the Maoist and early reform period have been relegated to the realm of fiction, revolutionary kitsch or are now simply passé, others remain very much alive in the popular imagination. A state-led project of promoting patriotic education has ensured the coexistence in commercial popular culture of revolutionary idols and contemporary celebrities, via memory sites associated with broadcast television, DVDs and the Internet, and the historical locations, museums and monuments of ‘red tourism.’

  6. Media coverage of celebrity DUIs: teachable moments or problematic social modeling? (United States)

    Smith, Katherine Clegg; Twum, Denise; Gielen, Andrea Carlson


    Alcohol in the media influences norms around use, particularly for young people. A recent spate of celebrity arrests for drinking and driving (DUI) has received considerable media attention. We asked whether these newsworthy events serve as teachable moments or problematic social modeling for young women. Qualitative analysis of US media coverage of four female celebrities (Michelle Rodriguez, Paris Hilton, Nicole Richie and Lindsay Lohan) was conducted over the year following their DUI arrest (December 2005 through June 2008). The media sample included five television and three print sources and resulted in 150 print and 16 television stories. Stories were brief, episodic and focused around glamorous celebrity images. They included routine discussion of the consequences of the DUI for the individual celebrities without much evidence of a consideration of the public health dimensions of drinking and driving or possible prevention measures. Our analysis found little material in the media coverage that dealt with preventing injury or promoting individual and collective responsibility for ensuring such protection. Media attention to such newsworthy events is a missed opportunity that can and should be addressed through media advocacy efforts.

  7. The synergy in green persuasion: Green celebrity endorsers in green advertising: A study of brand-endorser congruence effects in green advertising


    Blasche, J.; Ketelaar, P.E.


    This study examines celebrity endorser-brand congruence effects in green advertising on the ads' effectiveness. In an experimental survey, Dutch participants (197) saw ads with a congruent or incongruent celebrity endorser. Extending the match-up hypothesis to a novel match-up factor, greenness, the results show that pro-environmental celebrity endorsers yield more favourable attitudes towards the ad, the brand, and purchase intentions compared to non-green celebrity endorsers. Practitioners ...

  8. Pressure-Sensitive Paint Measurements on the NASA Common Research Model in the NASA 11-ft Transonic Wind Tunnel (United States)

    Bell, James H.


    The luminescence lifetime technique was used to make pressure-sensitive paint (PSP) measurements on a 2.7% Common Research Model in the NASA Ames 11ft Transonic Wind Tunnel. PSP data were obtained on the upper and lower surfaces of the wing and horizontal tail, as well as one side of the fuselage. Data were taken for several model attitudes of interest at Mach numbers between 0.70 and 0.87. Image data were mapped onto a three-dimensional surface grid suitable both for comparison with CFD and for integration of pressures to determine loads. Luminescence lifetime measurements were made using strobed LED (light-emitting diode) lamps to illuminate the PSP and fast-framing interline transfer cameras to acquire the PSP emission.

    Rosekind, Mark R.; Lebacqz, Victor J.; Gander, Philippa H.; Co, Elizabeth L.; Weldon, Keri J.; Smith, Roy M.; Miller, Donna L.; Gregory, Kevin B.; Statler, Irving C. (Technical Monitor)


    Since 1980, the NASA Ames Fatigue Countermeasures Program has been conducting research on sleep, circadian rhythms, and fatigue in a variety of flight operations 1. An original goal of the program was to return the scientific and operational knowledge to the aviation industry. To meet this goal, the NASA Ames Fatigue Countermeasures Program has created an Education and Training Module entitled, "Strategies for Alertness Management in Flight Operations." The Module was designed to meet three objectives: 1) explain the current state of knowledge about the physiological mechanisms underlying fatigue, 2) demonstrate how this knowledge can be applied to improve flight crew sleep, performance, and alertness, and 3) offer countermeasure recommendations. The Module is composed of two components: 1) a 60-minute live presentation provided by a knowledgeable individual and 2) a NASA/FAA Technical Memorandum (TM) that contains the presentation materials and appendices with complementary information. The TM is provided to all individuals attending the live presentation. The Module content is divided into three parts: 1) basic information on sleep, sleepiness, circadian rhythms, fatigue, and how flight operations affect these physiological factors, 2) common misconceptions about sleep, sleepiness, and fatigue, and 3) alertness management strategies. The Module is intended for pilots, management personnel, schedulers, flight attendants, and the many other individuals involved in the aviation system.

  11. NASA Systems Engineering Handbook (United States)

    Hirshorn, Steven R.; Voss, Linda D.; Bromley, Linda K.


    The update of this handbook continues the methodology of the previous revision: a top-down compatibility with higher level Agency policy and a bottom-up infusion of guidance from the NASA practitioners in the field. This approach provides the opportunity to obtain best practices from across NASA and bridge the information to the established NASA systems engineering processes and to communicate principles of good practice as well as alternative approaches rather than specify a particular way to accomplish a task. The result embodied in this handbook is a top-level implementation approach on the practice of systems engineering unique to NASA. Material used for updating this handbook has been drawn from many sources, including NPRs, Center systems engineering handbooks and processes, other Agency best practices, and external systems engineering textbooks and guides. This handbook consists of six chapters: (1) an introduction, (2) a systems engineering fundamentals discussion, (3) the NASA program project life cycles, (4) systems engineering processes to get from a concept to a design, (5) systems engineering processes to get from a design to a final product, and (6) crosscutting management processes in systems engineering. The chapters are supplemented by appendices that provide outlines, examples, and further information to illustrate topics in the chapters. The handbook makes extensive use of boxes and figures to define, refine, illustrate, and extend concepts in the chapters.

Particular emphasis will be given to the practices and procedures by which the SVS creates visualizations, from the hardware and software used to the structures and collaborations by which products are designed, developed, and delivered to customers. The web-based archival and delivery system for SVS visualizations at will also be described.

  15. Ariane: NASA's European rival (United States)

    The successful test launch of two three-quarter ton satellites in the European Space Agency's (ESA) Ariane rocket last June firmly placed ESA in competition with NASA for the lucrative and growing satellite launching market. Under the auspices of the private (but largely French-government financed) Arianespace company, ESA is already attracting customers to its three-stage rocket by offering low costs.According to recent reports [Nature, 292, pp. 785 and 788, 1981], Arianespace has been able to win several U.S. customers away from NASA, including Southern Pacific Communications, Western Union, RCA, Satellite Television Corporation, and GTE. Nature [292, 1981] magazine in an article entitled ‘More Trouble for the Hapless Shuttle’ suggests that it will be possible for Ariane to charge lower prices for a launch than NASA, even with the space shuttle.

    Doze, P. E-mail:; Elsinga, P.H.; Vries, E.F.J. de; Waarde, A. van; Vaalburg, W


    S-1'[{sup 18}F]-Fluorocarazolol (FCAR) is a fluorinated analog of the nonmutagenic beta-blocker carazolol (CAR). In former studies FCAR proved to be suitable for quantification of beta-adrenoceptors in vivo with positron emission tomography (PET). We report here that FCAR displays no acute toxicity in either rats or mice. However, FCAR induces a strong dose-related increase in the number of revertants in the Ames test. We conclude that FCAR yields mutagenic activity as measured by the Ames test.

  18. The Use of the Ames Test as a Tool for Addressing Problem-Based Learning in the Microbiology Lab

    Directory of Open Access Journals (Sweden)

    Eliana Rodríguez


    Full Text Available Our environment is full of potential carcinogens such as UV light, industrial pollutants, pesticides, and food additives, among others. It is estimated that 90% of all carcinogens are also mutagens. The Ames test is one of the most common tests for mutagens. In this problem-based learning activity, undergraduate biology students used the Ames test to screen a substance they provided, to see if it could be considered a mutagen. The idea of surveying substances used in everyday life appealed to our students, and helped engage them in this activity.

  19. Investigating the intra-nuclear cascade process using the reaction 136Xe on deuterium at 500 AMeV

    Directory of Open Access Journals (Sweden)

    Rejmund F.


    Full Text Available More than 600 residual nuclei, formed in the spallation of 136Xe projectiles impinging on deuterium at 500 AMeV of incident energy, have been unambiguously identified and their production cross sections have been determined with high accuracy. By comparing these data to others previously measured for the reactions 136Xe  +  p at 1 AGeV and 136Xe  +  p at 500 AMeV we investigated the role that neutrons play in peripheral collisions and to understand the energy dissipation in frontal collisions in spallation reactions.

  20. Report on the Stanford/KACST/AMES UVLED small satellite mission to demonstrate charge management of an electrically isolated proof mass for drag-free operation (United States)

    Saraf, Shailendhar

    A spacecraft demonstration of ultra-violet (UV) LEDs and UV LED charge management based on research done at Stanford University is being developed jointly by the King Abdulaziz City for Science and Technology (KACST) Saudi Arabia and NASA Ames Research Center, with an expected launch date of June 2014. This paper will report on the payload design and testing, mission preparation, satellite launch and payload bring -up in space. Mission lifetime is expected to be at least one month, during which time the ability for the UV LEDs to mitigate actual space-based charging and the effects of radiation on the UV LED device performance will be studied. Precise control over the potential of an electrically isolated proof mass is necessary for the operation of devices such as a Gravitational Reference Sensor (GRS) and satellite missions such as LISA. The mission will demonstrate that AlGaN UV LEDs operating at 255 nm are an effective low-cost, low-power and compact substitute for Mercury vapor lamps used in previous missions. The goal of the mission is to increase the UV LED device to TRL-9 and the charge management system to TRL-7.
