    PubMed

    Collins, Jannette

    2004-01-01

    Most radiologists are now creating their own image and text slides for oral presentations. PowerPoint software offers a tremendous number of options for personalizing slides. Having choices of font, color scheme, display options, sound, and graphics provide an opportunity to enhance a presentation in ways that were not possible with 35-mm slides and slide projectors. However, inappropriate use of PowerPoint features can substantially degrade the quality of a presentation. Many of the "rules" for creating an effective presentation given with slide projectors apply to electronic presentations, but some of the options available with only electronic presentations (eg, building, transitioning, and sound) necessitate new "rules." The article provides tips on how to develop effective text and image slides for electronic presentation by using PowerPoint, including the appropriate use of text, font, color, sound, graphics, slide display, and radiologic images.

  6. Increased interestingness of extraneous details in a multimedia science presentation leads to decreased learning.

    PubMed

    Mayer, Richard E; Griffith, Emily; Jurkowitz, Ilana T N; Rothman, Daniel

    2008-12-01

    In Experiment 1, students received an illustrated booklet, PowerPoint presentation, or narrated animation that explained 6 steps in how a cold virus infects the human body. The material included 6 high-interest details mainly about the role of viruses in sex or death (high group) or 6 low-interest details consisting of facts and health tips about viruses (low group). The low group outperformed the high group across all 3 media on a subsequent test of problem-solving transfer (d = .80) but not retention (d = .05). In Experiment 2, students who studied a PowerPoint lesson explaining the steps in how digestion works performed better on a problem-solving transfer test if the lesson contained 7 low-interest details rather than 7 high-interest details (d = .86), but the groups did not differ on retention (d = .26). In both experiments, as the interestingness of details was increased, student understanding decreased (as measured by transfer). Results are consistent with a cognitive theory of multimedia learning, in which highly interesting details sap processing capacity away from deeper cognitive processing of the core material during learning.

    2015-12-01

    PowerPoint presentations (PPTs) have become routine in medical colleges because of their flexible and varied presentation capabilities. Research indicates that students prefer PPTs over the chalk-and-talk method, and there is a lot of debate over advantages and disadvantages of PPTs. However, there is no clear evidence that PPTs improve student learning/performance. Furthermore, there are a variety of learning styles with sex differences in classrooms. It is the responsibility of teacher/facilitator and student to be aware of learning style preferences to improve learning. The present study asked the following research question: do PPTs equally affect the learning of students with different learning styles in a mixed sex classroom? After we assessed students' predominant learning style according to the sensory modality that one most prefers to use when learning, a test was conducted before and after a PPT to assess student performance. The results were analyzed using Student's t-test and ANOVA with a Bonferroni post hoc test. A z-test showed no sex differences in preferred learning styles. There was significant increase in posttest performance compared with that of the pretest in all types of learners of both sexes. There was also a nonsignificant relationship among sex, learning style, and performance after the PPT. A PPT is equally effective for students with different learning style preferences and supports mixed sex classrooms. PMID:26628661

  4. Education techniques for lifelong learning: giving a PowerPoint presentation: the art of communicating effectively.

    PubMed

    Collins, Jannette

    2004-01-01

    Effectiveness of an oral presentation depends on the ability of the speaker to communicate with the audience. An important part of this communication is focusing on two to five key points and emphasizing those points during the presentation. Every aspect of the presentation should be purposeful and directed at facilitating learners' achievement of the objectives. This necessitates that the speaker has carefully developed the objectives and built the presentation around attainment of the objectives. The best presentations are rehearsed, not so that the speaker memorizes exactly what he or she will say, but to facilitate the speaker's ability to interact with the audience and portray a relaxed, professional, and confident demeanor. Rehearsal also helps alleviate stage fright. The most useful method of controlling nervousness is to visualize success. When showing images, it is important to orient the audience with an adequate description, point out the relevant findings, and allow enough time for the audience to assimilate the information before moving on. This can be facilitated with appropriate use of a laser pointer, cursor, or use of builds and transitioning. A presentation should be designed to include as much audience participation as possible, no matter the size of the audience. Techniques to encourage audience participation include questioning, brainstorming, small-group activities, role-playing, case-based examples, and directed listening. It is first necessary to motivate and gain attention of the learner for learning to take place. This can be accomplished through appropriate use of humor, anecdotes, and quotations. Attention should be given to posture, body movement, eye contact, and voice when speaking, as how one appears to the audience will have an impact on their reaction to what is presented.

    2001-08-01

    Carousel slide presentations have been used for academic and clinical presentations since the late 1950s. However, advances in computer technology have caused a paradigm shift, and digital presentations are quickly becoming standard for clinical presentations. The advantages of digital presentations include cost savings; portability; easy updating capability; Internet access; multimedia functions, such as animation, pictures, video, and sound; and customization to augment audience interest and attention. Microsoft PowerPoint has emerged as the most popular digital presentation software and is currently used by many practitioners with and without significant computer expertise. The user-friendly platform of PowerPoint enables even the novice presenter to incorporate digital presentations into his or her profession. PowerPoint offers many advanced options that, with a minimal investment of time, can be used to create more interactive and professional presentations for lectures, patient education, and marketing. Examples of advanced PowerPoint applications are presented in a stepwise manner to unveil the full power of PowerPoint. By incorporating these techniques, medical practitioners can easily personalize, customize, and enhance their PowerPoint presentations. Complications, pitfalls, and caveats are discussed to detour and prevent misadventures in digital presentations. Relevant Web sites are listed to further update, customize, and communicate PowerPoint techniques. PMID:11496193

    The phrase "death by PowerPoint" was not born in the offices of Microsoft's competitors; it came straight from the hearts of victimized meeting attendees. Microsoft estimates that at least 30 million PowerPoint presentations are made daily, with many rightfully warranting death verdict assessment. Death sentences often result from a "construction…

  3. PowerPoint in the Classroom

    PubMed Central

    2004-01-01

    Note from the Editors Points of View (POV) addresses issues faced within life science education. Cell Biology Education has launched the POV feature to present two or more opinions published in tandem on a common topic. We consider POVs to be Op-Ed pieces designed to stimulate thought and dialog on significant educational issues. Each author has the opportunity to revise a POV after reading drafts of the other POVs. In this issue, we ask the question, Is PowerPoint the best instructional medium to use in your class? Everyone seems to have an opinion on Microsoft, but the intellectual merits of using PowerPoint (or similar software) is a growing question as states and institutions put more and more money into information technology and distance learning. Four POVs are presented: 1) David Keefe and James Willett provide their case why PowerPoint is an ideal teaching software. Keefe is an educational researcher at the Center for Technology in Learning at SRI International. Willett is a professor at George Mason University in the Departments of Microbial and Molecular Bioscience; as well as Bioinformatics and Computational Biology. 2) Kim McDonald highlights the causes of PowerPointlessness, a term which indicates the frequent use of PowerPoint as a crutch rather than a tool. She is a Bioscience Educator at the Shodor Education Foundation, Inc. 3) Diana Voss asks readers if PowerPoint is really necessary to present the material effectively or not. Voss is a Instructional Computing Support Specialist at SUNY Stony Brook. 4) Cynthia Lanius takes a light-hearted approach to ask whether PowerPoint is a technological improvement or just a change of pace for teacher and student presentations. Lanius is a Technology Integration Specialist in the Sinton (Texas) Independent School District. The authors span the range of teaching experiences and settings from which they bring different points of view to the debate. Readers are encouraged to participate in the online discussion forum hosted by CBE at www.cellbioed.org/discussion/public/main.cfm and/or contact the authors directly. PMID:15526063

  5. Presenting the Shuttle Main Engine Software

    NASA Technical Reports Server (NTRS)

    Schreur, Barbara

    1998-01-01

    Originally, this project was to produce an animated Powerpoint presentation of the 'Shuttle Engine and its Software' and to produce a web page with animation including the same materials but with greater detail in the description of the software. The principal emphasis was to be on the web page. Midway through the first year of the project, we were advised by the technical coordinator of this work at MSFC to concentrate on the web page alone. Also, the project was expanded to include a web presentation of the MRECS (Modular Rocket Control System). For the SSME project, the web page presentation has been completed. The integration of the animation into the web page is complete although we have been asked to speed up the animation. Also, the addition of greater detail to the description of the SSME controller software has been added. Much of the work on this program was done by students as their task for their senior project course, the capstone course of their program of study. The students gained a great deal from this project. They have learned to use VISIO, POWERPOINT, PHOTOSHOP, and several web page software packages. The starting point for this project was a PowerPoint presentation by the PI while on a Summer Faculty Fellowship at MSFC. For this project, about half of the drawings of the SSME were improved and about half were completely redrawn. The original still drawings have been animated to illustrate the fuel flow through the SSME system.

  18. Using Keynote to present radiology images.

    PubMed

    Ghoshhajra, Brian B; Techasith, Tust; Choy, Garry; Rojas, Carlos A; Pomerantz, Stuart R

    2011-10-01

    Numerous articles have offered instructions for working with advanced radiology images in Microsoft PowerPoint (Redmond, WA); however, no articles have detailed instructions to do the same on alternative presentation software. Apple Macintosh (Cupertino, CA) computers are gaining popularity with many radiologists, due in part to the availability of a powerful, free, open-source Digital Imaging and Communications in Medicine (DICOM) viewing and manipulating software OsiriX ( http://www.osirix-viewer.com ). Apple's own presentation software, Keynote, is particularly effective in dealing with medical images and cine clips. This article demonstrates how to use Apple's Keynote software to present radiology images and scrollable image stacks, without third-party add-on software. The article also illustrates how to compress media files and protect patient information in Keynote presentations. Lastly, it addresses the steps to converting between PowerPoint and Keynote file formats. Apple's Keynote software enables quick and efficient addition of multiple static images or scrollable image stacks, compression of media files, and removal of patient information. These functions can be accomplished by inexperienced users with no software modifications. PMID:20978920

    2010-01-01

    There are a number of sources available to prescribers to stay up to date about medicines. Prescribers in rural areas in developing countries however, may not able to access some of them. Interventions to improve prescribing can be educational, managerial, and regulatory or use a mix of strategies. Detailing by the pharmaceutical industry is widespread. Academic detailing (AD) has been classically seen as a form of continuing medical education in which a trained health professional such as a physician or pharmacist visits physicians in their offices to provide evidence-based information. Face-to-face sessions, preferably on an individual basis, clear educational and behavioural objectives, establishing credibility with respect to objectivity, stimulating physician interaction, use of concise graphic educational materials, highlighting key messages, and when possible, providing positive reinforcement of improved practices in follow-up visits can increase success of AD initiatives. AD is common in developed countries and certain examples have been cited in this review. In developing countries the authors have come across reports of AD in Pakistan, Sudan, Argentina and Uruguay, Bihar state in India, Zambia, Cuba, Indonesia and Mexico. AD had a consistent, small but potentially significant impact on prescribing practices. AD has much less resources at its command compared to the efforts by the industry. Steps have to be taken to formally start AD in Nepal and there may be specific hindering factors similar to those in other developing nations. PMID:21209521

    2015-12-01

    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    Web-based presentation tools are sometimes referred to as "next generation presentation tools" (EDUCAUSE, 2010). At the most basic level, these tools are simply online versions of traditional presentation software, such as Microsoft's PowerPoint or Apple's Keynote, but some services offer features like web-based collaboration, online presentation…

  13. Marketing your dental practice using microsoft powerpoint.

    PubMed

    Kotlow, L A

    2001-12-01

    Educating the parents of my patients about the techniques and specialized care pediatric dentists provide has always been a challenge. When I began my dental practice in 1974, the materials and audiovisual programs that were available for parental and patient education were of poor quality and often did not reflect my office philosophy. The multimedia material for pediatric dentistry was limited in scope and of little value in conveying to the parents and patients pediatric restorative procedures, causes of dental disease, caries prevention and patient management. Effective communication to the public can be divided into two areas: in-office marketing; and outside advertising. The primary focus of this discussion will be on in-house marketing of your dental practice using Microsoft PowerPoint. PMID:11862912

  19. Course Management Systems: Traveling Beyond Powerpoint Slides Online

    NASA Astrophysics Data System (ADS)

    Gauthier, A. J.; Impey, C. D.

    2004-12-01

    Course management systems (CMS) like WebCT, Blackboard, Astronomica, etc., have reached and surpassed their tipping point in higher education. They are no longer a technology-trendy item to use in a course, but rather an expected supplement to undergraduate courses. There is a well known disconnect between the student population of ''digital natives'' (1) and higher education instructors, the ''digital immigrants'' (1). What expectations and technology skills do the new generations of undergraduates have? How can instructors easily meet their students' needs? What needs do instructors have and what resources are available to meet those needs? In the past, instructors would create their own HTML web pages to post class materials like PowerPoint slides, homework, and announcements. How does an instructor-created web resource differ from a secure university run CMS? How can you make your university or college's CMS system into a productive learning tool and not just a repository for class materials and grades? How can the astronomy instructor benefit from integrating a CMS into their course? What are common student attitudes regarding CMS usage in a course? How are instructors using CMSs in innovative ways? Where on your campus can you get free help designing and implementing a CMS resource for your students? This presentation aims to answer these questions. Extensive literature reviews, formal surveys, case study reports, and educational research from the instructional technology community inform our astronomy teaching community of the answers. Highlights from innovative systems and uses of CMSs in undergraduate Astro 101 classrooms will be presented. Resources and further references will be made available as handouts. (1) M. Prensky.

    A male infant was diagnosed prenatally with a partial ornithine transcarbamylase (OTC) gene deletion and managed from birth. However, he displayed neurological abnormalities and developed pleural effusions, ascites and anasarca not solely explained by OTC deficiency (OTCD). Further evaluation of the gene locus using exon-specific PCR and high density SNP array copy number analysis revealed a 3.9Mb deletion from Xp11.4 to Xp21.1 including five additional gene deletions, three causing the known genetic diseases: Retinitis pigmentosa (RP3), X-linked chronic granulomatous disease (CGD) and McLeod syndrome. The case illustrates (1) the complexities of managing a patient withneonatal onset OTCD, CGD, RP3 and McLeod syndrome, (2) the need for detailed evaluation in seemingly “isolated” gene deletions and (3) the clinical utility of high density copy number analysis for rapidly characterizing chromosomal lesions.

  18. Adding power to PowerPoint. Add-ons and plug-ins.

    PubMed

    Giannavola, S

    2001-01-01

    Microsoft's PowerPoint (PPT) has been around for about ten years. It works on both the Macintosh and Windows platforms. Many users have a Macintosh at home and a Windows PC in the office and files can be easily transferred. Presentations magazine estimated that 85 percent of all presentations given in the U.S. last year used PPT. These presentations can be done as 35 mm slides, black and white or color overhead transparencies, electronic lectures or the software can be used to produce pages for Web sites. PPT has become the "Swiss Army Knife" for presenters and can be found everywhere. Since PPT has such a large share of the marketplace, a secondary market has developed to cater to PPT users who need something that didn't come in the box. These products are referred to as add-ons or plug-ins. They are available as commercial products, shareware or even directly from Microsoft. This article will look at several of these add-ons and discuss their possible use in a health care media production environment. PMID:11447780

    2009-04-01

    The Physicists in Primary Schools (PIPS) project is a joint venture initiated by the UK Women in Physics Group. A team from the University of Sheffield, with Engineering and Physical Sciences Research Council funding, has developed fun presentations and novel class activities using everyday articles for physicists to take into primary schools. The objectives are to instill enthusiasm in young children-including girls-through the enjoyment and excitement of physics, and support primary school teachers with a curriculum which includes many abstract concepts. All PIPS material is free to download from the Institute of Physics website (www.iop.org/pips), providing PowerPoint presentations and detailed explanations, as well as videos of the activities in classrooms. The topics are suitable for children age 4 to 11 years. There is interest in translating the presentations into other languages as there are few words on the slides and the material is likely valuable for older age groups. The presentations therefore have the potential to be useful worldwide.

  8. Effect of differing PowerPoint slide design on multiple-choice test scores for assessment of knowledge and retention in a theriogenology course.

    PubMed

    Root Kustritz, Margaret V

    2014-01-01

    Third-year veterinary students in a required theriogenology diagnostics course were allowed to self-select attendance at a lecture in either the evening or the next morning. One group was presented with PowerPoint slides in a traditional format (T group), and the other group was presented with PowerPoint slides in the assertion-evidence format (A-E group), which uses a single sentence and a highly relevant graphic on each slide to ensure attention is drawn to the most important points in the presentation. Students took a multiple-choice pre-test, attended lecture, and then completed a take-home assignment. All students then completed an online multiple-choice post-test and, one month later, a different online multiple-choice test to evaluate retention. Groups did not differ on pre-test, assignment, or post-test scores, and both groups showed significant gains from pre-test to post-test and from pre-test to retention test. However, the T group showed significant decline from post-test to retention test, while the A-E group did not. Short-term differences between slide designs were most likely unaffected due to required coursework immediately after lecture, but retention of material was superior with the assertion-evidence slide design.

    2012-12-01

    The disinformation campaign against climate science has been compared to a guerilla war whose tactics undermine the traditional checks and balances of science. One comprehensive approach has to been produce archives of generic responses such as the websites of RealClimate and SkepticalScience. We review our experiences with an alternative approach of detailed responses to a small number of high profile cases. Our particular examples were Professor Ian Plimer and Christopher Monckton, the Third Viscount Monckton of Brenchley, each of whom has been taken seriously by political leaders in our respective countries. We relate our experiences to comparable examples such as John Mashey's analysis of the Wegman report and the formal complaints about Lomborg's "Skeptical Environmentalist" and Durkin's "Great Global Warming Swindle". Our two approaches used contrasting approaches: an on-line video of a lecture vs an evolving compendium of misrepresentations. Additionally our approaches differed in the emphasis. The analysis of Monckton concentrated on the misrepresentation of the science, while the analysis of Plimer concentrated on departures from accepted scientific practice: fabrication of data, misrepresentation of cited sources and unattributed use of the work of others. Benefits of an evolving compendium were the ability to incorporate contributions from members of the public who had identified additional errors and the scope for addressing new aspects as they came to public attention. `Detailed debunking' gives non-specialists a reference point for distinguishing non-science when engaging in public debate.

As students, you are no exception the prospect of an oral presentation can be daunting, the pressure is on to make a good impression with your research. That we are scientists presenting sometimes very complicated scientific ideas and results need not necessarily be a recipe for a sleep inducing "death by PowerPoint" presentation, rather there are simple ways in which we can all try and make our presentations effective and captivating. This session aims to give you some all-round pointers on preparing and delivering an effective presentation that best conveys your ideas smoothly, understandably and, most important, succinctly.

    This color photo of Neptune's large satellite Triton was obtained on Aug. 24 1989 at a range of 530,000 kilometers (330,000 miles). The resolution is about 10 kilometers (6.2 miles), sufficient to begin to show topographic detail. The image was made from pictures taken through the green, violet and ultraviolet filters. In this technique, regions that are highly reflective in the ultraviolet appear blue in color. In reality, there is no part of Triton that would appear blue to the eye. The bright southern hemisphere of Triton, which fills most of this frame, is generally pink in tone as is the even brighter equatorial band. The darker regions north of the equator also tend to be pink or reddish in color. JPL manages the Voyager project for NASA's Office of Space Science, Washington, DC.

    22 September 2005 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows details among some of the eroded layer outcrops of the martian south polar region. Much of the south polar region of Mars is covered by a thick unit of layered material. For decades, the layers have been assumed to consist of a mixture of dust and ice, but it is equally possible that the materials are sedimentary rocks. This image was captured during southern spring, at a time when some of the surface was still covered by seasonal carbon dioxide (CO2) frost.

  16. Crowdsourcing detailed flood data

    NASA Astrophysics Data System (ADS)

    Walliman, Nicholas; Ogden, Ray; Amouzad*, Shahrzhad

    2015-04-01

    Over the last decade the average annual loss across the European Union due to flooding has been 4.5bn Euros, but increasingly intense rainfall, as well as population growth, urbanisation and the rising costs of asset replacements, may see this rise to 23bn Euros a year by 2050. Equally disturbing are the profound social costs to individuals, families and communities which in addition to loss of lives include: loss of livelihoods, decreased purchasing and production power, relocation and migration, adverse psychosocial effects, and hindrance of economic growth and development. Flood prediction, management and defence strategies rely on the availability of accurate information and flood modelling. Whilst automated data gathering (by measurement and satellite) of the extent of flooding is already advanced it is least reliable in urban and physically complex geographies where often the need for precise estimation is most acute. Crowdsourced data of actual flood events is a potentially critical component of this allowing improved accuracy in situations and identifying the effects of local landscape and topography where the height of a simple kerb, or discontinuity in a boundary wall can have profound importance. Mobile 'App' based data acquisition using crowdsourcing in critical areas can combine camera records with GPS positional data and time, as well as descriptive data relating to the event. This will automatically produce a dataset, managed in ArcView GIS, with the potential for follow up calls to get more information through structured scripts for each strand. Through this local residents can provide highly detailed information that can be reflected in sophisticated flood protection models and be core to framing urban resilience strategies and optimising the effectiveness of investment. This paper will describe this pioneering approach that will develop flood event data in support of systems that will advance existing approaches such as developed in the in the UK in the more generalised RASP project (DEFRA and the Environment Agency), and in line with the expressed needs of the ABI (Association of British Insurers) and National Flood Forum. The detailed data produced will also support improved flood risk assessment for the provision of affordable insurance.

    A detailed quantitative mechanism for the oxidation of benzene in both argon and nitrogen diluted systems is presented. Computed ignition delay time for argon diluted mixtures are in satisfactory agreement with experimental results for a wide range of initial conditions. An experimental temperature versus time profile for a nitrogen diluted oxidation was accurately matched and several concentration profiles were matched qualitatively. Application of sensitivity analysis has given approximate rate constant expressions for the two dominant heat release reactions, the oxidation of C6H5 and C5H5 radicals by molecular oxygen.

    2010-01-01

    Objectives Due to the increasing use of electronic patient records and other health care information technology, we see an increase in requests to utilize these data. A highly level of standardization is required during the gathering of these data in the clinical context in order to use it for analyses. Detailed Clinical Models (DCM) have been created toward this purpose and several initiatives have been implemented in various parts of the world to create standardized models. This paper presents a review of DCM. Methods Two types of analyses are presented; one comparing DCM against health care information architectures and a second bottom up approach from concept analysis to representation. In addition core parts of the draft ISO standard 13972 on DCM are used such as clinician involvement, data element specification, modeling, meta information, and repository and governance. Results Six initiatives were selected: Intermountain Healthcare, 13606/OpenEHR Archetypes, Clinical Templates, Clinical Contents Models, Health Level 7 templates, and Dutch Detailed Clinical Models. Each model selected was reviewed for their overall development, involvement of clinicians, use of data types, code bindings, expressing semantics, modeling, meta information, use of repository and governance. Conclusions Using both a top down and bottom up approach to comparison reveals many commonalties and differences between initiatives. Important differences include the use of or lack of a reference model and expressiveness of models. Applying clinical data element standards facilitates the use of conceptual DCM models in different technical representations. PMID:21818440

    Alkhateeb, Fadi M; Doucette, William R

    2009-01-01

    E-detailing means using digital technology: internet, video conferencing and interactive voice response. There are two types of e-detailing: interactive (virtual) and video. Currently, little is known about what factors influence physicians' adoption of e-detailing. The objectives of this study were to test a model of physicians' adoption of e-detailing and to describe physicians using e-detailing. A mail survey was sent to a random sample of 2000 physicians practicing in Iowa. Binomial logistic regression was used to test the model of influences on physician adoption of e-detailing. On the basis of Rogers' model of adoption, the independent variables included relative advantage, compatibility, complexity, peer influence, attitudes, years in practice, presence of restrictive access to traditional detailing, type of specialty, academic affiliation, type of practice setting and control variables. A total of 671 responses were received giving a response rate of 34.7%. A total of 141 physicians (21.0%) reported using of e-detailing. The overall adoption model for using either type of e-detailing was found to be significant. Relative advantage, peer influence, attitudes, type of specialty, presence of restrictive access and years of practice had significant influences on physician adoption of e-detailing. The model of adoption of innovation is useful to explain physicians' adoption of e-detailing. PMID:19306198

  8. Using Microsoft PowerPoint as an Astronomical Image Analysis Tool

    NASA Astrophysics Data System (ADS)

    Beck-Winchatz, Bernhard

    2006-12-01

    Engaging students in the analysis of authentic scientific data is an effective way to teach them about the scientific process and to develop their problem solving, teamwork and communication skills. In astronomy several image processing and analysis software tools have been developed for use in school environments. However, the practical implementation in the classroom is often difficult because the teachers may not have the comfort level with computers necessary to install and use these tools, they may not have adequate computer privileges and/or support, and they may not have the time to learn how to use specialized astronomy software. To address this problem, we have developed a set of activities in which students analyze astronomical images using basic tools provided in PowerPoint. These include measuring sizes, distances, and angles, and blinking images. In contrast to specialized software, PowerPoint is broadly available on school computers. Many teachers are already familiar with PowerPoint, and the skills developed while learning how to analyze astronomical images are highly transferable. We will discuss several practical examples of measurements, including the following: -Variations in the distances to the sun and moon from their angular sizes -Magnetic declination from images of shadows -Diameter of the moon from lunar eclipse images -Sizes of lunar craters -Orbital radii of the Jovian moons and mass of Jupiter -Supernova and comet searches -Expansion rate of the universe from images of distant galaxies

The high-quality visualizations of large and strongly deformed bubbles disclose so far unseen features of the dynamics inside the bubble, such as a mushroom-like flattened jet-tip, crown formation and micro-droplets. We also find that jetting near a free surface reduces the collapse time relative to the Rayleigh time.

    PubMed

    De Wael, K; Lepot, L

    2015-01-01

    During the commission of crimes blood can be transferred to the clothing of the offender or on other crime related objects. Bloodstain particles are sub-millimetre sized flakes that are lost from dried bloodstains. The nature of these red particles is easily confirmed using spectroscopic methods. In casework, bloodstain particles showing highly detailed morphological features were observed. These provided a rationale for a series of experiments described in this work. It was found that the "largest" particles are shed from blood deposited on polyester and polyamide woven fabrics. No particles are lost from the stains made on absorbent fabrics and from those made on knitted fabrics. The morphological features observed in bloodstain particles can provide important information on the substrates from which they were lost. PMID:25437904

    Detailed fuel spray analyses are a necessary input to the analytical modeling of the complex mixing and combustion processes which occur in advanced combustor systems. It is anticipated that by controlling fuel-air reaction conditions, combustor temperatures can be better controlled, leading to improved combustion system durability. Thus, a research program is underway to demonstrate the capability to measure liquid droplet size, velocity, and number density throughout a fuel spray and to utilize this measurement technique in laboratory benchmark experiments. The research activities from two contracts and one grant are described with results to data. The experiment to characterize fuel sprays is also described. These experiments and data should be useful for application to and validation of turbulent flow modeling to improve the design systems of future advanced technology engines.

    Ohzeki, Masayuki; Ichiki, Akihisa

    2015-07-01

    An improved method for driving a system into a desired distribution, for example, the Gibbs-Boltzmann distribution, is proposed, which makes use of an artificial relaxation process. The standard techniques for achieving the Gibbs-Boltzmann distribution involve numerical simulations under the detailed balance condition. In contrast, in the present study we formulate the Langevin dynamics, for which the corresponding Fokker-Planck operator includes an asymmetric component violating the detailed balance condition. This leads to shifts in the eigenvalues and results in the acceleration of the relaxation toward the steady state. The numerical implementation demonstrates faster convergence and shorter correlation time, and the technique of biased event sampling, Nemoto-Sasa theory, further highlights the efficacy of our method.

    2005-09-18

    High-energy electron cooling for RHIC presents many unique features and challenges. An accurate estimate of the cooling times requires detailed simulation of the electron cooling process. The first step towards such calculations is to have an accurate description of the cooling force. Numerical simulations are being used to explore various features of the friction force which appear due to several effects, including the anisotropy of the electron distribution in velocity space and the effect of a strong solenoidal magnetic field. These aspects are being studied in detail using the VORFAL code, which explicitly resolves close binary collisions. Results are compared with available asymptotic and empirical formulas and also, using the BETACOOL code, with direct numerical integration of less approximate expressions over the specified electron distribution function.

    Abstract Conferences and Meetings feature many presentations on a tight schedule. The Session Timer system provides an electronic display for showing the remaining time in a presentation. It provides continuous feedback so the speaker can judge the pace throughout a presentation. The timer automates the job so the session chairman does not have to awkwardly interrupt the speaker.

  13. The Finer Details: Climate Modeling

    NASA Technical Reports Server (NTRS)

    2000-01-01

    If you want to know whether you will need sunscreen or an umbrella for tomorrow's picnic, you can simply read the local weather report. However, if you are calculating the impact of gas combustion on global temperatures, or anticipating next year's rainfall levels to set water conservation policy, you must conduct a more comprehensive investigation. Such complex matters require long-range modeling techniques that predict broad trends in climate development rather than day-to-day details. Climate models are built from equations that calculate the progression of weather-related conditions over time. Based on the laws of physics, climate model equations have been developed to predict a number of environmental factors, for example: 1. Amount of solar radiation that hits the Earth. 2. Varying proportions of gases that make up the air. 3. Temperature at the Earth's surface. 4. Circulation of ocean and wind currents. 5. Development of cloud cover. Numerical modeling of the climate can improve our understanding of both the past and, the future. A model can confirm the accuracy of environmental measurements taken. in, the past and can even fill in gaps in those records. In addition, by quantifying the relationship between different aspects of climate, scientists can estimate how a future change in one aspect may alter the rest of the world. For example, could an increase in the temperature of the Pacific Ocean somehow set off a drought on the other side of the world? A computer simulation could lead to an answer for this and other questions. Quantifying the chaotic, nonlinear activities that shape our climate is no easy matter. You cannot run these simulations on your desktop computer and expect results by the time you have finished checking your morning e-mail. Efficient and accurate climate modeling requires powerful computers that can process billions of mathematical calculations in a single second. The NCCS exists to provide this degree of vast computing capability.

    1992-01-01

    The small subunit rRNA sequence of twenty archaea, members of the Methanomicrobiales, permits a detailed phylogenetic tree to be inferred for the group. The tree confirms earlier studies, based on far fewer sequences, in showing the group to be divided into two major clusters, temporarily designated the "methanosarcina" group and the "methanogenium" group. The tree also defines phylogenetic relationships within these two groups, which in some cases do not agree with the phylogenetic relationships implied by current taxonomic names--a problem most acute for the genus Methanogenium and its relatives. The present phylogenetic characterization provides the basis for a consistent taxonomic restructuring of this major methanogenic taxon.

    For those that can see stereo, stereo scatterplots provide a powerful method of displaying data that has three dimensional structure. While not the best quality stereo presentation method, color anaglyph stereo is easily produced on raster color devices. This simplicity makes color anaglyph stereo a useful tool for exploratory interactive data analysis. Attention to several details can enhance anaglyph scatterplots. Issues of perspective projection ambiguity, pixel-rounding noise, crosstalk between images, and the use of additional depth cues including overplotting, and shifts in point size, intensity, and hue are addressed.

  3. Adult recollections of childhood memories: What details can be recalled?

    Wells, Christine; Morrison, Catriona M; Conway, Martin A

    2014-01-01

    In a memory survey, adult respondents recalled, dated, and described two earliest positive and negative memories that they were highly confident were memories. They then answered a series of questions that focused on memory details such as clothing, duration, weather, and so on. Few differences were found between positive and negative memories, which on average had 4/5 details and dated to the age of 6/6.5 years. Memory for details about activity, location, and who was present was good; memory for all other details was poorer or at floor. Taken together, these findings indicate that (full) earliest memories may be considerably later than previously thought and that they rarely contain the sort of specific details targeted by professional investigators. The resulting normative profile of memory details reported here can be used to evaluate overly specific childhood autobiographical memories and to identify memory details with a low probability of recall.

    1990-07-16

    More oil property data, in the form of recent crude oil assays, have been made available for two Vietnamese crude oils, Bach Ho (White Tiger) and Dai Hung (Big Bear). Crude oil data presented earlier gave limited properties of the crudes,which are from the Miocene formations. Further analyses have been conducted on Bach Ho crude from the Oligocene formations. Production from Oligocene is far more representative of the oils produced from the Bach Ho field and marketed worldwide. Currently, Bach Ho is the only producing field. Dai Hung is expected to be in production during the next few years. Bach Ho is currently producing at the rate of 20,000 b/d. That figure is projected to grow to 100,000 b/d by 1992 and to 120,000 b/d by 1995. Detailed assays of both crude oils are presented.

  7. Recovering and preventing loss of detailed memory: differential rates of forgetting for detail types in episodic memory.

    Episodic memories undergo qualitative changes with time, but little is known about how different aspects of memory are affected. Different types of information in a memory, such as perceptual detail, and central themes, may be lost at different rates. In patients with medial temporal lobe damage, memory for perceptual details is severely impaired, while memory for central details is relatively spared. Given the sensitivity of memory to loss of details, the present study sought to investigate factors that mediate the forgetting of different types of information from naturalistic episodic memories in young healthy adults. The study investigated (1) time-dependent loss of "central" and "peripheral" details from episodic memories, (2) the effectiveness of cuing with reminders to reinstate memory details, and (3) the role of retrieval in preventing forgetting. Over the course of 7 d, memory for naturalistic events (film clips) underwent a time-dependent loss of peripheral details, while memory for central details (the core or gist of events) showed significantly less loss. Giving brief reminders of the clips just before retrieval reinstated memory for peripheral details, suggesting that loss of details is not always permanent, and may reflect both a storage and retrieval deficit. Furthermore, retrieving a memory shortly after it was encoded prevented loss of both central and peripheral details, thereby promoting retention over time. We consider the implications of these results for behavioral and neurobiological models of retention and forgetting. PMID:26773100

Comparisons are also presented with geoid heights from satellite solutions for geocentric station coordinates in North America, the Caribbean, and Europe.

  11. Detailed Chemical Kinetic Modeling of Hydrazine Decomposition

    NASA Technical Reports Server (NTRS)

    Meagher, Nancy E.; Bates, Kami R.

    2000-01-01

    The purpose of this research project is to develop and validate a detailed chemical kinetic mechanism for gas-phase hydrazine decomposition. Hydrazine is used extensively in aerospace propulsion, and although liquid hydrazine is not considered detonable, many fuel handling systems create multiphase mixtures of fuels and fuel vapors during their operation. Therefore, a thorough knowledge of the decomposition chemistry of hydrazine under a variety of conditions can be of value in assessing potential operational hazards in hydrazine fuel systems. To gain such knowledge, a reasonable starting point is the development and validation of a detailed chemical kinetic mechanism for gas-phase hydrazine decomposition. A reasonably complete mechanism was published in 1996, however, many of the elementary steps included had outdated rate expressions and a thorough investigation of the behavior of the mechanism under a variety of conditions was not presented. The current work has included substantial revision of the previously published mechanism, along with a more extensive examination of the decomposition behavior of hydrazine. An attempt to validate the mechanism against the limited experimental data available has been made and was moderately successful. Further computational and experimental research into the chemistry of this fuel needs to be completed.

  16. Detailed mechanism for oxidation of benzene

    NASA Technical Reports Server (NTRS)

    Bittker, David A.

    1990-01-01

    A detailed mechanism for the oxidation of benzene is presented and used to compute experimentally obtained concentration profiles and ignition delay times over a wide range of equivalence ratio and temperature. The computed results agree qualitatively with all the experimental trends. Quantitative agreement is obtained with several of the composition profiles and for the temperature dependence of the ignition delay times. There are indications, however, that some important reactions are as yet undiscovered in this mechanism. Recent literature expressions have been used for the rate coefficients of most important reactions, except for some involving phenol. The discrepancy between the phenol pyrolysis rate coefficient used in this work and a recent literature expression remains to be explained.

    Color constancy is an important problem in machine vision and image processing fields. We propose a new method in this paper that is based on detail information description to estimate the chromaticity of the light source and restore the real color property of captured images. The main idea of the proposed approach is that according to human vision characteristics use the interest information in an image to estimate the lighting condition of real scene. To approve the proposed method, two well-known algorithms are selected and their contrast results are also presented. It is shown in this paper that the proposed approach performs better than other traditional methods for color constancy most of the time.

    2015-05-26

    The screening of a reduced yet diverse and synthesizable region of the chemical space is a critical step in drug discovery. The ZINC database is nowadays routinely used to freely access and screen millions of commercially available compounds. We collected ∼125 million compounds from chemical catalogs and the ZINC database, yielding more than 68 million unique molecules, including a large portion of described natural products (NPs) and drugs. The data set was filtered using advanced medicinal chemistry rules to remove potentially toxic, promiscuous, metabolically labile, or reactive compounds. We studied the physicochemical properties of this compilation and identified millions of NP-like, fragment-like, inhibitors of protein-protein interactions (i-PPIs) like, and drug-like compounds. The related focused libraries were subjected to a detailed scaffold diversity analysis and compared to reference NPs and marketed drugs. This study revealed thousands of diverse chemotypes with distinct representations of building block combinations among the data sets. An analysis of the stereogenic and shape complexity properties of the libraries also showed that they present well-defined levels of complexity, following the tendency: i-PPIs-like < drug-like < fragment-like < NP-like. As the collected compounds have huge interest in drug discovery and particularly virtual screening and library design, we offer a freely available collection comprising over 37 million molecules under: http://pbox.pharmaceutical-bioinformatics.org , as well as the filtering rules used to build the focused libraries described herein.

    A collection of documents provides further detailed information about an optoelectronic instrument that measures the pH of an aqueous cell-culture medium to within 0.1 unit in the range from 6.5 to 7.5. The instrument at an earlier stage of development was reported in Optoelectronic Instrument Monitors pH in a Culture Medium (MSC-23107), NASA Tech Briefs, Vol. 28, No. 9 (September 2004), page 4a. To recapitulate: The instrument includes a quartz cuvette through which the medium flows as it is circulated through a bioreactor. The medium contains some phenol red, which is an organic pH-indicator dye. The cuvette sits between a light source and a photodetector. [The light source in the earlier version comprised red (625 nm) and green (558 nm) light-emitting diodes (LEDs); the light source in the present version comprises a single green- (560 nm)-or-red (623 nm) LED.] The red and green are repeatedly flashed in alternation. The responses of the photodiode to the green and red are processed electronically to obtain the ratio between the amounts of green and red light transmitted through the medium. The optical absorbance of the phenol red in the green light varies as a known function of pH. Hence, the pH of the medium can be calculated from the aforesaid ratio.

    Emotional arousal and negative affect enhance recall of central aspects of an event. However, the role of discrete emotions in selective memory processing is understudied. Undergraduates were asked to recall and rate autobiographical memories of eight emotional events. Details of each memory were rated as central or peripheral to the event. Significance of the event, vividness, reliving and other aspects of remembering were also rated for each event. Positive affect enhanced recall of peripheral details. Furthermore, the impairment of peripheral recall was greatest in memories of anger, not of fear. Reliving the experience at retrieval was negatively correlated with recall of peripheral details for some emotions (e.g., anger) but not others (e.g., fear), irrespective of similarities in affect and intensity. Within individuals, recall of peripheral details was correlated with less belief in the memory’s accuracy and more likelihood to recall the memory from one’s own eyes (i.e., a field perspective).

  12. Detailed modelling of the 21-cm forest

    NASA Astrophysics Data System (ADS)

    Semelin, B.

    2016-01-01

    The 21-cm forest is a promising probe of the Epoch of Reionization. The local state of the intergalactic medium (IGM) is encoded in the spectrum of a background source (radio-loud quasars or gamma-ray burst afterglow) by absorption at the local 21-cm wavelength, resulting in a continuous and fluctuating absorption level. Small-scale structures (filaments and minihaloes) in the IGM are responsible for the strongest absorption features. The absorption can also be modulated on large scales by inhomogeneous heating and Wouthuysen-Field coupling. We present the results from a simulation that attempts to preserve the cosmological environment while resolving some of the small-scale structures (a few kpc resolution in a 50 h-1 Mpc box). The simulation couples the dynamics and the ionizing radiative transfer and includes X-ray and Lyman lines radiative transfer for a detailed physical modelling. As a result we find that soft X-ray self-shielding, Ly α self-shielding and shock heating all have an impact on the predicted values of the 21-cm optical depth of moderately overdense structures like filaments. A correct treatment of the peculiar velocities is also critical. Modelling these processes seems necessary for accurate predictions and can be done only at high enough resolution. As a result, based on our fiducial model, we estimate that LOFAR should be able to detect a few (strong) absorptions features in a frequency range of a few tens of MHz for a 20 mJy source located at z = 10, while the SKA would extract a large fraction of the absorption information for the same source.

  13. Ancillary-service details: Dynamic scheduling

    Hirst, E.; Kirby, B.

    1997-01-01

    Dynamic scheduling (DS) is the electronic transfer from one control area to another of the time-varying electricity consumption associated with a load or the time-varying electricity production associated with a generator. Although electric utilities have been using this technique for at least two decades, its use is growing in popularity and importance. This growth is a consequence of the major changes under way in US bulk-power markets, in particular efforts to unbundle generation from transmission and to increase competition among generation providers. DS can promote competition and increase choices. It allows consumers to purchase certain services from entities outside their physical-host area and it allows generators to sell certain services to entities other than their physical host. These services include regulation (following minute-to-minute variations in load) and operating reserves, among others. Such an increase in the number of possible suppliers and customers should encourage innovation and reduce the costs and prices of providing electricity services. The purpose of the project reported here was to collect and analyze data on utility experiences with DS. Chapter 2 provides additional details and examples of the definitions of DS. Chapter 3 explains why DS might be an attractive service that customers and generators, as well as transmission providers, might wan to use. Chapter 4 presents some of the many current DS examples the authors uncovered in their interviews. Chapter 5 discusses the costs and cost-effectiveness of DS. Chapter 6 explains what they believe can and cannot be electronically moved from one control area to another, primarily in terms of the six ancillary services that FERC defined in Order 888. Chapter 7 discusses the need for additional research on DS.

    This article describes a graduate class in presentation skills ("PClass") as a model for how a class with similar objectives, expectations and culture might be mounted for undergraduates. The required class is given for students in neuroscience and physiology programs at the University of North Carolina at Chapel Hill; I describe the class in the years I led it, from 2003-2012. The class structure centered on peer rehearsal, critiquing of PowerPoint, and chalk talks by the students; video-recording of student talks for later review by the student with the instructor; and presentation of polished talks in a formal setting. A different faculty visitor to the class each week gave the students a variety of perspectives. The students also gained insight into their own evolving skills by discussing the strengths and weaknesses of seminars given by visitors to the campus. A unique feature of the class was collaboration with a professional actor from the University's Department of Dramatic Arts, who helped the students develop techniques for keeping the attention of an audience, for speaking with confidence, and for controlling nervousness. The undergraduate campus would be expected to lend itself to this sort of interdisciplinary faculty cooperation. In addition, students worked on becoming adept at designing and presenting posters, introducing speakers graciously and taking charge of the speaker's question session, and speaking to a lay audience.

  16. Ubiquitous Presenter: A Tablet PC-based System to Support Instructors and Students

    NASA Astrophysics Data System (ADS)

    Price, Edward; Simon, Beth

    2009-12-01

    Digital lecturing systems (computer and projector, often with PowerPoint) offer physics instructors the ability to incorporate graphics and the power to share and reuse materials. But these systems do a poor job of supporting interaction in the classroom. For instance, with digital presentation systems, instructors have limited ability to spontaneously respond to student questions. This limitation is especially acute during classroom activities such as problem solving, Peer Instruction, and Interactive Lecture Demonstrations (ILDs).2 A Tablet PC, a laptop computer with a stylus that can be used to "write" on the screen, provides a way for instructors to add digital ink spontaneously to a presentation in progress. The Tablet PC can be a powerful tool for teaching,3,4 especially when combined with software systems specifically designed to leverage digital ink for pedagogical uses. Ubiquitous Presenter (UP) is one such freely available system.5 Developed at the University of California, San Diego, and based on Classroom Presenter,6 UP allows the instructor to ink prepared digital material (such as exported PowerPoint slides) in real time in class. Ink is automatically archived stroke by stroke and can be reviewed through a web browser (by both students and instructors). The system also supports spontaneous in-class interaction through a web interface—students with web-enabled devices (Tablet PCs, regular laptops, PDAs, and cell phones) can make text-, ink-, or image-based submissions on the instructor's slides. The instructor can review and then project submitted slides to the class and add additional ink, so that material generated by students can be a focus for discussion. A brief video showing UP in action is at http://physics.csusm.edu/UP. In this article, we describe UP and give examples of how UP can support the physics classroom.

    A current research effort is underway at the NASA Langley Research Center to achieve a detailed understanding of important phenomena present when a supersonic flow undergoes chemical reaction. A computer program has been developed to study the details of such flows. The program has been constructed to consider the multicomponent diffusion and convection of important species, the finite-rate reaction of these species, and the resulting interaction between the fluid mechanics and chemistry. Code results from the analysis of a spatially developing and reacting mixing layer are presented, and conclusions are drawn regarding the structure of the evolving layer and its associated flame.

  20. Making detailed predictions makes (some) predictions worse

    NASA Astrophysics Data System (ADS)

    Kelly, Theresa F.

    In this paper, we investigate whether making detailed predictions about an event makes other predictions worse. Across 19 experiments, 10,895 participants, and 415,960 predictions about 724 professional sports games, we find that people who made detailed predictions about sporting events (e.g., how many hits each baseball team would get) made worse predictions about more general outcomes (e.g., which team would win). We rule out that this effect is caused by inattention or fatigue, thinking too hard, or a differential reliance on holistic information about the teams. Instead, we find that thinking about game-relevant details before predicting winning teams causes people to give less weight to predictive information, presumably because predicting details makes information that is relatively useless for predicting the winning team more readily accessible in memory and therefore incorporated into forecasts. Furthermore, we show that this differential use of information can be used to predict what kinds of games will and will not be susceptible to the negative effect of making detailed predictions.

  1. Contrast-detail curves for liver CT.

    1992-01-01

    Contrast-detail curves were constructed for liver computed tomographic (CT) images using an objective method. Stimuli were created by superimposing disks at specified locations on sets of 92 normal liver CT images. Bright and dark disks of 9 sizes and 36 possible image contrasts were used. Sets of 92 stimuli were rendered on film at five window widths (64, 128, 256, 512, and 1024 HU). The contrast-detail (CD) curve flattened substantially for disks larger than 7-mm diameter, and its slope (on a log-log plot) was less than predicted from signal-detection theory. Manipulation of display window manipulation had little impact on this disks' visibility. The results indicate that human observers have difficulty visualizing large, low-contrast details on liver CT scans, and suggest that narrowing the display window will have little effect on this limitation.

  2. Strain Analysis of Stretched Tourmaline Crystals Using ImageJ, Microsoft Excel and PowerPoint

    2012-12-01

    This poster describes an undergraduate structural geology lab exercise utilizing the Mohr's circle diagram for finite strain, constructed using measurements obtained from stretched tourmaline crystals. A small building housing HVAC equipment at the south end of West Chester University's Recitation Hall (itself made of serpentinite) is constructed of early-Cambrian Chickies Quartzite. Stretched tourmaline crystals, with segments joined by fibrous quartz, are visible on many surfaces (presumably originally bedding). While the original orientation of any stone is unknown, these rocks provide an opportunity for a short field exercise during a two-hour lab period and a great base for conducting strain analysis. It is always fun to ask how many in the class have ever noticed the tourmaline (few have). Students take photos using their cell phones or cameras. Since strain is a ratio the absolute size of the tourmaline crystals is immaterial. Nonetheless, this is a good opportunity to remind students of the importance of including a scale in their photographs. The photos are opened in ImageJ and the line tool is used to determine the original and final lengths of selected crystals. Students calculate strain parameters using Microsoft Excel. Then, we use Adobe Illustrator or the drafting capabilities of Microsoft PowerPoint 2010 to follow Ramsay and Huber's techniques using a Mohr's circle construction to determine the finite strain ellipse. If a stretching direction can be estimated, elongation of two crystals is all that is required to determine the strain ratio. If no stretching direction is apparent, three crystals are required for a more complicated analysis that allows for determination of the stretching direction, as well as the strain ratio.

    Many physicians want to be good platform speakers; however, few of us have the background and training necessary to be an outstanding public speaker. Yes, we all have slide decks and PowerPoint programs provided to us so that we can turn our backs to the audience and read the verbiage on the slides. But does that technique generate useful information to the audience? Or if speaking to a lay audience, does that kind of talk make the audience members get out their cell phones and call the office to make an appointment in our practice? Probably not. This article will provide suggestions that will enhance your speaking and presentation skills. This, in turn, will make you a darling of the pharma industry and encourage potential patients in your audience to become patients in your practice. PMID:24765742

    Condensation of atoms from the vapor into a third sound resonance is expected to be capable of acoustic amplification. This results from normal to superfluid conversion that coherently accommodates atoms into the third sound velocity field. Consideration of third sound in light of the equilibrium detailed balance between vapor particles and the superfluid film provides further evidence that acoustic amplification is attainable.

    Today's PCs incorporate multiple CPUs and GPUs and are easily arranged in clusters for high-performance, interactive graphics. We present an approach based on hierarchical, screen-space tiles to parallelizing rendering with level of detail. Adapt tiles, render tiles, and machine tiles are associated with CPUs, GPUs, and PCs, respectively, to efficiently parallelize the workload with good resource utilization. Adaptive tile sizes provide load balancing while our level of detail system allows total and independent management of the load on CPUs and GPUs. We demonstrate our approach on parallel configurations consisting of both single PCs and a cluster of PCs.

    2014-11-01

    In order to surmount the infrared-image object differentiation difficulty caused by the blurred image edge, a kind of adaptive filter based infrared-image nonlinear edge enhancement technology was proposed in this paper. This technology integrates image nonlinear edge-sharpening and Multi-scale analyze method. The approach of Gauss pyramid structure can enhance detail information by using non-linear algorithms in different scales. The enhanced detail information is then added back to the original image iteratively. While saving the image edge information it can filter image noise and edge distortion caused by edge-sharpening and improve image's clarity and SNR obviously. Gray scale grads was defined based on gray linear increment, image edge enhancement arithmetic can be real time realized, and has been applied in high performance thermal imager. As it is shown in experiments, this algorithm has practicality and potential application value in the field of infrared images contrast enhancement

    This manual discusses building and building component behavior during earthquakes, and provides suggested details for seismic resistance which have shown by experience to provide adequate performance during earthquakes. Special design and construction practices are also described which, although they might be common in some high-seismic regions, may not be common in low and moderate seismic-hazard regions of the United States. Special attention is given to describing the level of detailing appropriate for each seismic region. The UBC seismic criteria for all seismic zones is carefully examined, and many examples of connection details are given. The general scope of discussion is limited to materials and construction types common to Department of Energy (DOE) sites. Although the manual is primarily written for professional engineers engaged in performing seismic-resistant design for DOE facilities, the first two chapters, plus the introductory sections of succeeding chapters, contain descriptions which are also directed toward project engineers who authorize, review, or supervise the design and construction of DOE facilities. 88 refs., 188 figs.

    A detailed chemical kinetic model for ethanol oxidation has been developed and validated against a variety of experimental data sets. Laminar flame speed data obtained from a constant volume bomb, ignition delay data behind reflected shock waves, and ethanol oxidation product profiles from a turbulent flow reactor were used in this study. Very good agreement was found in modeling the data sets obtained from the three different experimental systems. The computational modeling results show that high temperature ethanol oxidation exhibits strong sensitivity to the fall-off kinetics of ethanol decomposition, branching ratio selection for c2h5oh+oh=products, and reactions involving the hydroperoxyl (HO2) radical.

    2005-01-13

    A detailed chemical kinetic mechanism for 2,4,6-tri-nitrotoluene (TNT) has been developed to explore problems of explosive performance and soot formation during the destruction of munitions. The TNT mechanism treats only gas-phase reactions. Reactions for the decomposition of TNT and for the consumption of intermediate products formed from TNT are assembled based on information from the literature and on current understanding of aromatic chemistry. Thermodynamic properties of intermediate and radical species are estimated by group additivity. Reaction paths are developed based on similar paths for aromatic hydrocarbons. Reaction-rate constant expressions are estimated from the literature and from analogous reactions where the rate constants are available. The detailed reaction mechanism for TNT is added to existing reaction mechanisms for RDX and for hydrocarbons. Computed results show the effect of oxygen concentration on the amount of soot precursors that are formed in the combustion of RDX and TNT mixtures in N{sub 2}/O{sub 2} mixtures.

  9. HUBBLE CAPTURES DETAILED IMAGE OF URANUS' ATMOSPHERE

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Hubble Space Telescope has peered deep into Uranus' atmosphere to see clear and hazy layers created by a mixture of gases. Using infrared filters, Hubble captured detailed features of three layers of Uranus' atmosphere. Hubble's images are different from the ones taken by the Voyager 2 spacecraft, which flew by Uranus 10 years ago. Those images - not taken in infrared light - showed a greenish-blue disk with very little detail. The infrared image allows astronomers to probe the structure of Uranus' atmosphere, which consists of mostly hydrogen with traces of methane. The red around the planet's edge represents a very thin haze at a high altitude. The haze is so thin that it can only be seen by looking at the edges of the disk, and is similar to looking at the edge of a soap bubble. The yellow near the bottom of Uranus is another hazy layer. The deepest layer, the blue near the top of Uranus, shows a clearer atmosphere. Image processing has been used to brighten the rings around Uranus so that astronomers can study their structure. In reality, the rings are as dark as black lava or charcoal. This false color picture was assembled from several exposures taken July 3, 1995 by the Wide Field Planetary Camera-2.

  10. Detailed balance of the Feynman micromotor

    NASA Astrophysics Data System (ADS)

    Abbott, Derek; Davis, Bruce R.; Parrondo, Juan M. R.

    1999-09-01

    One existing implication of micromotors is that they can be powered by rectifying non-equilibrium thermal fluctuations or mechanical vibrations via the so-called Feynman- micromotor. An example of mechanical rectification is found in the batteryless wristwatch. The original concept was described in as early as 1912 by Smoluchowski and was later revisited in 1963 by Feynman, in the context of rectifying thermal fluctuations to obtain useful motion. It has been shown that, although rectification is impossible at equilibrium, it is possible for the Feynman-micromotor to perform work under non-equilibrium conditions. These concepts can now be realized by MEMS technology and may have exciting implications in biomedicine - where the Feynman- micromotor can be used to power a smart pill, for example. Previously, Feynman's analysis of the motor's efficiency has been shown to be flawed by Parrondo and Espanol. We now show there are further problems in Feynman's treatment of detailed balance. In order to design and understand this device correctly, the equations of detailed balance must be found. Feynman's approach was to use probabilities based on energies and we show that this is problematic. In this paper, we demonstrate corrected equations using level crossing probabilities instead. A potential application of the Feynman-micromotor is a batteryless nanopump that consists of a small MEMS chip that adheres to the skin of a patient and dispense nanoliter quantities of medication. Either mechanical or thermal rectification via a Feynman- micromotor, as the power source, is open for possible investigation.

  13. Report Details Solar Radiation Alert and Recommendations

    NASA Astrophysics Data System (ADS)

    2006-06-01

    High-energy particles from the Sun and from regions beyond the solar system constantly bombard Earth. Thanks to the planet's atmosphere and magnetic field, comsic radiation is not a significant threat to those rooted on terra firma. But airline crew and passengers flying at high altitudes, or over the poles where the Earth's magnetic field provides no protection, are particularly vulnerable to unpredictable flares on the Sun's surface that launch streams of sub-atomic particles toward Earth. The report, ``Solar Radiation Alert System,'' published by the Federal Aviation Administration (FAA) and the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado, Boulder, in July 2005 (www.faa.gov/library/reports/medical/oamtechreports/2000s/media/0514.pdf) details in alert system designed to estimate the ionizing radiation at aircraft flight altitudes and, depending on the resulting dose rate, issue a warning.

    1994-07-11

    In a continuing effort to be more candid about Department of Energy nuclear weapons programs, Energy Secretary Hazel R. O'Leary recently declassified a substantial amount of information. On June 27, she revealed details about total US weapons-grade uranium production, testing of a bomb made of reactor-grade plutonium, radiation experiments conducted on humans since the 1920s, and underground and atmospheric nuclear weapons tests. O'Leary explains the new revelations by saying thousands of people in meetings across the country this year have told her that openness in government is very important. DOE is responding today in a manner that both satisfies the strong public interest and respects critical national security requirements.

    2005-01-01

    This new Hubble image -- one among the largest ever produced with the Earth-orbiting observatory -- shows the most detailed view so far of the entire Crab Nebula ever made. The Crab is arguably the single most interesting object, as well as one of the most studied, in all of astronomy. The image is the largest image ever taken with Hubble's WFPC2 workhorse camera.

    The Crab Nebula is one of the most intricately structured and highly dynamical objects ever observed. The new Hubble image of the Crab was assembled from 24 individual exposures taken with the NASA/ESA Hubble Space Telescope and is the highest resolution image of the entire Crab Nebula ever made.

    Rowley, N.; Grar, N.; Trotta, M.

    2007-10-15

    The 'experimental barrier distribution' provides a parameter-free representation of experimental heavy-ion capture cross sections that highlights the effects of entrance-channel couplings. Its relation to the s-wave transmission is discussed, and in particular it is shown how the full capture cross section can be generated from an l=0 coupled-channels calculation. Furthermore, it is shown how this transmission can be simply exploited in calculations of quasifission and evaporation-residue cross sections. The system {sup 48}Ca+{sup 154}Sm is studied in detail. A calculation of the compound-nucleus spin distribution reveals a possible energy dependence of barrier weights due to polarization arising from target and projectile quadrupole phonon states; this effect also gives rise to an entrance-channel 'extra-push'.

  17. Hubble Captures Detailed Image of Uranus' Atmosphere

    NASA Technical Reports Server (NTRS)

    1996-01-01

    Hubble Space Telescope has peered deep into Uranus' atmosphere to see clear and hazy layers created by a mixture of gases. Using infrared filters, Hubble captured detailed features of three layers of Uranus' atmosphere.

    Hubble's images are different from the ones taken by the Voyager 2 spacecraft, which flew by Uranus 10 years ago. Those images - not taken in infrared light - showed a greenish-blue disk with very little detail.

    The infrared image allows astronomers to probe the structure of Uranus' atmosphere, which consists of mostly hydrogen with traces of methane. The red around the planet's edge represents a very thin haze at a high altitude. The haze is so thin that it can only be seen by looking at the edges of the disk, and is similar to looking at the edge of a soap bubble. The yellow near the bottom of Uranus is another hazy layer. The deepest layer, the blue near the top of Uranus, shows a clearer atmosphere.

    Image processing has been used to brighten the rings around Uranus so that astronomers can study their structure. In reality, the rings are as dark as black lava or charcoal.

    This false color picture was assembled from several exposures taken July 3, 1995 by the Wide Field Planetary Camera-2.

    The Wide Field/Planetary Camera 2 was developed by the Jet Propulsion Laboratory and managed by the Goddard Spaced Flight Center for NASA's Office of Space Science.

    2004-04-28

    A new opacity code, TOPAZ, which explicitly includes configuration term structure in the bound-bound transitions is being developed. The goal is to extend the current capabilities of detailed term accounting opacity codes such as OPAL that are limited to lighter elements of astrophysical interest. At present, opacity calculations of heavier elements use statistical methods that rely on the presence of myriad spectral lines for accuracy. However, statistical approaches have been shown to be inadequate for astrophysical opacity calculations. An application of the TOPAZ code will be to study the limits of statistical methods. Comparisons of TOPAZ to other opacity codes as well as experiments are presented.

  19. Description of Axial Detail for ROK Fuel

    SciTech Connect

    Trellue, Holly R; Galloway, Jack D

    2012-04-20

    For the purpose of NDA simulations of the ROK fuel assemblies, we have developed an axial burnup distribution to represent the pins themselves based on gamma scans of rods in the G23 assembly. For the purpose of modeling the G23 assembly (both at ORNL and LANL), the pin-by-pin burnup map as simulated by ROK is being assumed to represent the radial burnup distribution. However, both DA and NDA results indicate that this simulated estimate is not 100% correct. In particular, the burnup obtained from the axial gamma scan of 7 pins does not represent exactly the same 'average' pin burnup as the ROK simulation. Correction for this discrepancy is a goal of the well-characterized assembly task but will take time. For now, I have come up with a correlation for 26 axial points of the burnup as obtained by gamma scans of 7 different rods (C13, G01, G02, J11, K10, L02, and M04, neglecting K02 at this time) to the average burnup given by the simulation for each of the rods individually. The resulting fraction in each axial zone is then averaged for the 7 different rods so that it can represent every fuel pin in the assembly. The burnup in each of the 26 axial zones of rods in all ROK assemblies will then be directly adjusted using this fraction, which is given in Table 1. Note that the gamma scan data given by ROK for assembly G23 included a length of {approx}3686 mm, so the first 12 mm and the last 14 mm were ignored to give an actual rod length of {approx}366 cm. To represent assembly F02 in which no pin-by-pin burnup distribution is given by ROK, we must model it using infinitely-reflected geometry but can look at the effects of measuring in different axial zones by using intermediate burnup files (i.e. smaller burnups than 28 GWd/MTU) and determining which axial zone(s) each burnup represents. Details for assembly F02 are then given in Tables 2 and 3, which is given in Table 1 and has 44 total axial zones to represent the top meter in explicit detail in addition to the other 26 zones. Note that the MCNP files for F02 were created using the Monte Carlo burnup linkage code Monteburns, which saves MCNP input files with detailed compositions as a function of burnup. The 'intermediate burnup files' produced for F02 include a cooling time of 27 years. The axial location of 5 spacers was also included in the ROK F02 assembly in which each spacer contained a length of 3.81 cm. Note that due to the nature of Monteburns, which was run in a special fashion for this problem, the step number increments after the 27 year decay, so the second column of Table 2 refers to the step number that should be used in the Monteburns files.

  3. Collaborative recall of details of an emotional film.

    Collaborative inhibition refers to the phenomenon that when several people work together to produce a single memory report, they typically produce fewer items than when the unique items in the individual reports of the same number of participants are combined (i.e., nominal recall). Yet, apart from this negative effect, collaboration may be beneficial in that group members remove errors from a collaborative report. Collaborative inhibition studies on memory for emotional stimuli are scarce. Therefore, the present study examined both collaborative inhibition and collaborative error reduction in the recall of the details of emotional material in a laboratory setting. Female undergraduates (n = 111) viewed a film clip of a fatal accident and subsequently engaged in either collaborative (n = 57) or individual recall (n = 54) in groups of three. The results show that, across several detail categories, collaborating groups recalled fewer details than nominal groups. However, overall, nominal recall produced more errors than collaborative recall. The present results extend earlier findings on both collaborative inhibition and error reduction to the recall of affectively laden material. These findings may have implications for the applied fields of forensic and clinical psychology. PMID:24628679

  4. Inverse sequential simulation: Performance and implementation details

    For good groundwater flow and solute transport numerical modeling, it is important to characterize the formation properties. In this paper, we analyze the performance and important implementation details of a new approach for stochastic inverse modeling called inverse sequential simulation (iSS). This approach is capable of characterizing conductivity fields with heterogeneity patterns difficult to capture by standard multiGaussian-based inverse approaches. The method is based on the multivariate sequential simulation principle, but the covariances and cross-covariances used to compute the local conditional probability distributions are computed by simple co-kriging which are derived from an ensemble of conductivity and piezometric head fields, in a similar manner as the experimental covariances are computed in an ensemble Kalman filtering. A sensitivity analysis is performed on a synthetic aquifer regarding the number of members of the ensemble of realizations, the number of conditioning data, the number of piezometers at which piezometric heads are observed, and the number of nodes retained within the search neighborhood at the moment of computing the local conditional probabilities. The results show the importance of having a sufficiently large number of all of the mentioned parameters for the algorithm to characterize properly hydraulic conductivity fields with clear non-multiGaussian features.

    This paper describes the ACPMAPS computing system -- its purpose, its hardware architecture, how the system is used, and relevant programming paradigms and concepts. Features of the hardware and software will be discussed in some detail, both quantitative and qualitative. This should give some perspective as to the suitability of the ACPMAPS system for various classes of applications, and as to where this system stands in the spectrum of today's supercomputers. The ACPMAPS project at Fermilab was initiated in 1987 as a collaborations between the Advanced Computer Program (now the Computer R D department) and the lattice gauge physicists in the Theory department. ACPMAPS is an acronym for Advanced Computer Program Multiple Array Processor System -- this acronym is no longer accurate, but the name has stuck. Although research physics computations were done on ACPMAPS as early as 1989, the full-scale system was commissioned as a reliable physics tool in early 1991. The original ACPMAPS was a 5 Gflop (peak) system. An upgrade by a factor of ten in computer power and memory size, but substituting a new CPU board, will occur during early 1991 -- this is referred to as the new ACPMAPS Upgrade or 50 GF ACPMAPS. The appellation ACPMAPS II has also been applied to the upgrade; this is somewhat of a misnomer, since only one of five major components was changed.

    2016-04-01

    This study depends on KIC 9641031 eclipsing binary with a chromospherically active component. There are three type variations, such as geometrical variations due to eclipses, sinusoidal variations due to the rotational modulations, and also flares, in the light curves. Taking into account results obtained from observations in the Kepler Mission Database, we discuss the details of chromospheric activity. The sinusoidal light variations due to rotational modulation and the flare events were modelled. 92 different data subsets separated using the analytic models were modelled separately to obtain the cool spot configuration. Acording to the model, there are two active regions separated by about 180° longitudinally between the latitudes of +50° and +100°. 240 flares, whose parameters were computed, were detected. Using these parameters, the OPEA model was derived, in which the Plateau value was found to be 1.232±0.069 s, and half-life parameter was found as 2291.7 s. The flare frequency N1 was found as 0.41632 h-1, while the flare frequency N2 was found as 0.00027. Considering these parameters together with the orbital period variations demonstrates that the period variations depend on chromospheric activity. Comparing the system with its analogue, the activity level of KIC 9641031 is remarkably lower than the others.

    The complex and highly variable structure of the submarine continental margin of central Peru is revealed by geophysical surveys and geologic sampling completed in 1985. The surveys were conducted in preparation for deep scientific drilling to be undertaken by the Ocean Drilling Program in November-December 1986. More than 11,000 km/sup 2/ of sea floor were mapped using the SeaMARC II side-scan sonar and bathymetry system; 1500 km of multichannel seismic reflection profiles and 4000 km of single-channel seismic data were shot; and many coring, dredging, and heat-flow stations were obtained. The data permit construction of detailed three-dimensional geologic maps of the region. These maps show that the ancient metamorphic rocks of South America extend close to the trench axis and apparently have undergone a history of truncation and subsidence related to the subduction of the Nazca oceanic plate. Adjacent segments of the Peru forearc have dramatically different structure and appear to have had differing tectonic histories. The margin is disrupted by extensive (primarily tensional) faulting; the larger faults extend perpendicular to the strike of the trench and often serve as conduits for diapirs and mud volcanoes. Living chemosynthetic clams were dredged from 3800-m depth along one of these fault trends, suggesting that active fluid venting occurs at depth on the continental wall of the Peru Trench.

    Differences in speech articulation among four emotion types, neutral, anger, sadness, and happiness are investigated by analyzing tongue tip, jaw, and lip movement data collected from one male and one female speaker of American English. The data were collected using an electromagnetic articulography (EMA) system while subjects produce simulated emotional speech. Pitch, root-mean-square (rms) energy and the first three formants were estimated for vowel segments. For both speakers, angry speech exhibited the largest rms energy and largest articulatory activity in terms of displacement range and movement speed. Happy speech is characterized by largest pitch variability. It has higher rms energy than neutral speech but articulatory activity is rather comparable to, or less than, neutral speech. That is, happy speech is more prominent in voicing activity than in articulation. Sad speech exhibits longest sentence duration and lower rms energy. However, its articulatory activity is no less than neutral speech. Interestingly, for the male speaker, articulation for vowels in sad speech is consistently more peripheral (i.e., more forwarded displacements) when compared to other emotions. However, this does not hold for female subject. These and other results will be discussed in detail with associated acoustics and perceived emotional qualities. [Work supported by NIH.

  10. Details of tetrahedral anisotropic mesh adaptation

    Jensen, Kristian Ejlebjerg; Gorman, Gerard

    2016-04-01

    We have implemented tetrahedral anisotropic mesh adaptation using the local operations of coarsening, swapping, refinement and smoothing in MATLAB without the use of any for- N loops, i.e. the script is fully vectorised. In the process of doing so, we have made three observations related to details of the implementation: 1. restricting refinement to a single edge split per element not only simplifies the code, it also improves mesh quality, 2. face to edge swapping is unnecessary, and 3. optimising for the Vassilevski functional tends to give a little higher value for the mean condition number functional than optimising for the condition number functional directly. These observations have been made for a uniform and a radial shock metric field, both starting from a structured mesh in a cube. Finally, we compare two coarsening techniques and demonstrate the importance of applying smoothing in the mesh adaptation loop. The results pertain to a unit cube geometry, but we also show the effect of corners and edges by applying the implementation in a spherical geometry.

    2013-12-01

    We examine Atlantic Ocean circulation during the Miocene based on published modelling and data. It has long been recognised that the Atlantic Ocean played a key role in climate changes throughout the Quaternary and determining whether this was the case earlier in the Cenozoic may be important for understanding the details of Miocene climate evolution. Current geochemical, sedimentological and micropaleontologic evidence allows for multiple interpretations of deep water activity, which is further hampered by a lack of precise dating of ocean gateway closures. Previous ocean modelling studies have shown strong increases in deep water formation due to closure of the Panama gateway but have disagreed on the oceanographic importance of the Tethys gateway and bathymetry of the far North Atlantic. This combination of ambiguous data and conflicting modelling results leaves the current state of knowledge of the Miocene ocean lacking. We propose several avenues of research to improve our knowledge of the Miocene Atlantic Ocean, which will ultimately improve our understanding of its response to climate change and vice versa.

    A semi-empirical model is presented which describes the operating characteristics of resistojet and arcjet engines. Propellants considered include hydrogen, ammonia and hydrazine. Specific engine design and performance correlations are derived from previously published contractor reports, conference and journal papers of the past three decades. Fundamental performance relationships are identified and correlating parameters derived to describe engine operation over a wide range of input powers and propellant mass flow rates. Outputs are presented from a computer program formulated using these modeling relationships. Comparisons are made with present electrothermal engine designs and examples are presented to illustrate the usefulness of the models in predicting engine operation as a function of changes in engine geometry and operating modes. 33 refs.

  14. Local detailed balance: a microscopic derivation

    NASA Astrophysics Data System (ADS)

    Bauer, M.; Cornu, F.

    2015-01-01

    Thermal contact is the archetype of non-equilibrium processes driven by constant non-equilibrium constraints when the latter are enforced by reservoirs exchanging conserved microscopic quantities. At a mesoscopic scale only the energies of the macroscopic bodies are accessible together with the configurations of the contact system. We consider a class of models where the contact system, as well as macroscopic bodies, have a finite number of possible configurations. The global system, with only discrete degrees of freedom, has no microscopic Hamiltonian dynamics, but it is shown that, if the microscopic dynamics is assumed to be deterministic and ergodic and to conserve energy according to some specific pattern, and if the mesoscopic evolution of the global system is approximated by a Markov process as closely as possible, then the mesoscopic transition rates obey three constraints. In the limit where macroscopic bodies can be considered as reservoirs at thermodynamic equilibrium (but with different intensive parameters), the mesoscopic transition rates turn into transition rates for the contact system and the third constraint becomes local detailed balance; the latter is generically expressed in terms of the microscopic exchange entropy variation, namely the opposite of the variation of the thermodynamic entropy of the reservoir involved in a given microscopic jump of the contact system configuration. For a finite-time evolution after contact has been switched on, we derive a fluctuation relation for the joint probability of the heat amounts received from the various reservoirs. The generalization to systems exchanging energy, volume and matter with several reservoirs, with a possible conservative external force acting on the contact system, is given explicitly.

    Orbis World Globes creates inflatable globes-Earthballs-in many sizes that depict Earth as it is seen from space, complete with atmospheric cloud cover. Orbis designs and produces the most visually authentic replicas of Earth ever created, and NASA took notice of Orbis globes and employed a 16-inch diameter EarthBall for an educational film it made aboard the STS-45 shuttle mission. Orbis later collaborated with NASA to create two 16-foot diameter world globes for display at the 2002 Olympic Winter Games in Salt Lake City, using more detailed satellite imagery. The satellite image now printed on all Orbis globes displays 1-kilometer resolution and is 21,600 by 43,200 pixels in size, and Orbis globes are otherwise meteorologically accurate, though the cloud cover has been slightly reduced in order for most of the landforms to be visible. Orbis also developed the exclusive NightGlow Cities feature, enabling EarthBalls to display the world's cities as they appear as the Earth revolves from daylight into night. Orbis inflatable globes are available in sizes from 1 to 100 feet in diameter, with the most common being the standard 16-inch and 1-meter diameter EarthBalls. Applications include educational uses from preschools to universities, games, and for a variety of display purposes at conferences, trade shows, festivals, concerts, and parades. A 16-foot diameter Orbis globe was exhibited at the United Nations' World Urban Forum, in Vancouver, Canada; the Space 2006 conference, in San Jose, California; and the X-Prize Cup Personal Spaceflight Exposition in Las Cruces, New Mexico.

    2015-01-01

    Rhinoscleroma (RS) is a chronic specific disease of nose and upper respiratory passages caused by Klebsiella rhinoscleromatis bacilli. It is endemic in Egypt and in sporadic areas worldwide. Diagnosis of RS depends on identification of the pathognomonic Mickulicz cells (MCs) which is most prominent during granulomatous phase but spares or absent during catarrhal or sclerotic phases of the disease. This study aimed to identify the potential diagnostic features of nasal RS when MCs are absent. Nasal biopsies from 125 patients complaining of chronic nasal symptoms were retrieved for this study; including 72 chronic non specific inflammatory lesions and 53 RS diagnosed by PAS and Geimsa stains. The detailed histological differences among the two groups were measured statistically. RS was frequently a bilateral disease (P < 0.05) of young age (P < 0.001) with a female predominance (P < 0.05) and usually associated with nasal crustations (P < 0.001). Five strong histological indicators of RS were specified by univariate binary logistic regression analyses including squamous metaplasia (OR 27.2, P < 0.0001), dominance of plasma cells (OR 12.75, P < 0.0001), Russell bodies (OR 8.83, P < 0.0001), neutrophiles (OR 3.7, P < 0.001) and absence of oesinophiles (OR 12.0, P < 0.0001). According to Multivariate analysis, the diagnostic features of RS in absence of MCs can be classified into major criteria including dominance of plasma cells infiltration and absence of oesinophiles and minor criteria including young age, female gender, bilateral nasal involvement, nasal crustation, squamous metaplasia, Russell bodies, and neutrophiles. The diagnostic model using the two major criteria confirmed or excluded RS in 84.3% of the investigated cases. PMID:26339415

    Herbinet, Olivier; Pitz, William J.; Westbrook, Charles K.

    2008-08-15

    A detailed chemical kinetic mechanism has been developed and used to study the oxidation of methyl decanoate, a surrogate for biodiesel fuels. This model has been built by following the rules established by Curran and co-workers for the oxidation of n-heptane and it includes all the reactions known to be pertinent to both low and high temperatures.

    A detailed chemical kinetic mechanism has been developed and used to study the oxidation of methyl decanoate, a surrogate for biodiesel fuels. This model has been built by following the rules established by Curran et al. for the oxidation of n-heptane and it includes all the reactions known to be pertinent to both low and high temperatures.

  2. Hořava-Lifshitz gravity: Detailed balance revisited

    NASA Astrophysics Data System (ADS)

    Vernieri, Daniele; Sotiriou, Thomas P.

    2012-03-01

    We attempt a critical reconsideration of “detailed balance” as a principle that can be used to restrict the proliferation of couplings in Hořava-Lifshitz gravity. We reexamine the shortcomings that have been usually associated with it in the literature and we argue that easy remedies can be found for all of them within the framework of detailed balance, and that the most persistent of them are actually related to projectability. We show that, once projectability is abandoned, detailed balance reduces the number of independent couplings by roughly an order of magnitude and imposes only one restriction that constitutes a phenomenological concern: the size of the (bare) cosmological constant is unacceptably large. Remarkably, this restriction (which is present in the projectable version as well) has been so far underappreciated in the literature. Optimists might prefer to interpret it as a potential blessing in disguise, as it allows one to entertain the idea of a miraculous cancellation between the bare cosmological constant and the (still poorly understood) vacuum energy contribution.

  5. On detailed 3D reconstruction of large indoor environments

    2015-03-01

    In this paper we present techniques for highly detailed 3D reconstruction of extra large indoor environments. We discuss the benefits and drawbacks of low-range, far-range and hybrid sensing and reconstruction approaches. The proposed techniques for low-range and hybrid reconstruction, enabling the reconstruction density of 125 points/cm3 on large 100.000 m3 models, are presented in detail. The techniques tackle the core challenges for the above requirements, such as a multi-modal data fusion (fusion of a LIDAR data with a Kinect data), accurate sensor pose estimation, high-density scanning and depth data noise filtering. Other important aspects for extra large 3D indoor reconstruction are the point cloud decimation and real-time rendering. In this paper, we present a method for planar-based point cloud decimation, allowing for reduction of a point cloud size by 80-95%. Besides this, we introduce a method for online rendering of extra large point clouds enabling real-time visualization of huge cloud spaces in conventional web browsers.

    1982-01-01

    Detailed observations are presented of a region near the terrestrial plasmapause where narrowband electromagnetic radiation (previously called escaping nonthermal continuum radiation) is being generated. These observations show a direct correspondence between the narrowband radio emissions and electron cyclotron harmonic waves near the upper hybrid resonance frequency. In addition, electromagnetic radiation propagating in the Z-mode is observed in the source region which provides an extremely accurate determination of the electron plasma frequency and, hence, density profile of the source region. The data strongly suggest that electrostatic waves and not Cerenkov radiation are the source of the banded radio emissions and define the coupling which must be described by any viable theory.

    PubMed

    Libbey, M

    1989-01-01

    This symposium was devoted to the consideration of Dr. Mary Libbey's treatment of a 22-year-old woman. The unfolding of the analysand's symbiotic attachment to her mother, the devastating sequelae of her having been the stable center of a pathological family that devoted itself to the care of a severely handicapped sibling, and her immersion in unresolved mourning form the center of this richly detailed and carefully reported case study. In addition, four verbatim sessions are reported, one from each year of the first two years of treatment, and two from the third year of treatment. Dr. Epstein's discussion, praising Dr. Libbey's therapeutic skill, makes note of the issues in the patient's family of origin that served to prepare her to feel endangered in the treatment. Dr. Epstein's view is that the analyst has created an analytic situation that, because it is minimally impinging, allows the patient to become increasingly aware of her unmet needs in a way that is tolerable and minimally "destabilizing to the symbiotically based organization of her internal self and object world." In the climate of safety created in the treatment, the patient can begin to complete the work of mourning for her sister, friend, and aunt, a process of mourning that would be impossible in the context of her nuclear family, centered as it is on a mother who cannot tolerate separation. Limit-setting in the treatment is seen to be reassuring to the patient, facilitating as it does the analyst's commitment to maintaining the integrity of the analytic situation. Dr. Schafer's discussion, while in agreement with Dr. Epstein in recognizing the excellence of the presentation and the sensitivity and hard work that had gone into both the treatment and the clinical presentation, included some specific and focused observations about the transference and countertransference situations prevailing in this treatment and also some suggestions for creating a more consistently safe analytic atmosphere for this particular patient and others like her. Dr. Schafer proposes that the therapist acknowledge to herself and accept as well as possible the inevitable feeling of helplessness such patients provoke. In a more concrete vein, he advocates talking in the first person declarative as much as possible, preferring "I don't understand" to the more standard "What do you mean?" or "Why?" The therapist is encouraged to eschew interpreting what the patient says about the therapeutic relationship for a long time, and, further, he suggests not quickly connecting or easily reducing the therapeutic relationship to childhood prototypes.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:2516334

    We investigated the sleep problems and sleep habits of adolescents at three public primary schools and two high schools. Our study included 428 Turkish school children (244 girls and 184 boys). We used a questionnaire to determine the time they went to sleep at night; waking time in the morning; incidence of nightmares, snoring, daytime sleepiness, and intrafamilial physical trauma; concentration difficulty in class; and school success. The students were divided into age-related groups (group 1 = 11 to 13 years of age; group 2 = 14 to 15 years; group 3 = 16 to 18 years). The time they went to sleep was mostly between 10 and 11 p.m. in groups 1 and 2, and 11 to 12 p.m. in group 3. Difficulty in falling asleep was reported by 16.8 to 19.6% of the students in the three groups. Difficulty in waking up in the morning was reported by 12.7% of group 1, 16.0% of group 2, and 16.8% of group 3. Snoring was present in 12.1% of females and 22.0% of males. The occurrence of one nightmare in the preceding 3 months was reported by 11.3% of the students; 17.9% of the students reported having nightmares several times. Daytime sleepiness was present in 65.1%, and concentration difficulty was present in 56.8% of the students. We conclude that difficulty in falling asleep, snoring, and daytime sleepiness may be seen in adolescents who are in both primary and high schools. Watching inappropriate programs and movies on television and intrafamilial physical trauma may cause nightmares and sleeping problems in these adolescents. Students and families should be educated about the importance of sleep in academic performance. Countries' public health policies should address sleep problems and related educational activities.

    1998-01-01

    Recent interest in low cost, reliable access to space has generated increased interest in advanced technology approaches to space transportation systems. A key to the success of such programs lies in the development of advanced propulsion systems capable of achieving the performance and operations goals required for the next generation of space vehicles. One extremely promising approach involves the combination of rocket and air-breathing engines into a rocket-based combined-cycle engine (RBCC). A key element of that engine is the rocket ejector that is utilized in the zero to Mach two operating regime. Studies of RBCC engine concepts are not new and studies dating back thirty years are well documented in the literature. However, studies focused on the rocket ejector mode of the RBCC cycle are lacking. The present investigation utilizes an integrated experimental and computation fluid dynamics (CFD) approach to examine critical rocket ejector performance issues. In particular, the development of a predictive methodology capable of performance prediction is a key objective in order to analyze thermal choking and its control, primary/secondary pressure matching considerations, and effects of nozzle expansion ratio. To achieve this objective, the present study emphasizes obtaining new data using advanced optical diagnostics such as Schlieren photography and Raman spectroscopy, and CFD techniques to investigate mixing in the rocket ejector mode. A new research facility for the study of the rocket ejector mode has been developed. In the last milestone report, the operational capabilities of this research facility were described. In this milestone report, the experimentally obtained measurements for CFD code validation are presented and discussed.

    A woven coronary artery is a rare congenital vascular variation that involves the separation of the artery into several thin channels, which later merge distally to form a single lumen. This mesh of intertwining small vessels may occur anywhere along the vessel and may be present in multiple coronaries. Although generally a benign incidental finding, there have been reported cases of associated ischemia, thrombus and atherosclerotic plaque formation and complications with cardiac intervention procedures. In this review, we have analyzed and compiled all the reported data pertaining to woven coronary arteries and highlighted its relevance to clinical practice. Clin.

    1977-07-01

    The twins presented in this article showed similarities in their physical make-up to a very high degree. Statistically, however, it is the blood picture which holds the "trump card" in this plethora of evidence supporting monozygous twinning, and it is an essential prerequisite in any presentation of this nature. It is perhaps noteworthy that, while only one of the twins sucked his thumb habitually, there was no difference in the degree of postnormality of the posterior teeth but merely a change in the interincisor relation and in the palatal height. It can clearly be seen from the study of these two twins that the differences between them were very small indeed and could quite easily be classed as individual variations within the same identical genetic pattern. Similarly, in any other identical twins, the way in which one differs from another must be to a similarly small degree or the cause of the difference must clearly be attributable to environmental or acquired influences. Differences which cannot be classed as other than genetic show us that the twins are fraternal or dizygous and, therefore, no more alike than would be two brothers of differing ages. PMID:267437

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

    Though emotion conveys memory benefits, it does not enhance memory equally for all aspects of an experience nor for all types of emotional events. In this review, I outline the behavioral evidence for arousal’s focal enhancements of memory and describe the neural processes that may support those focal enhancements. I also present behavioral evidence to suggest that these focal enhancements occur more often for negative experiences than for positive ones. This effect of valence appears to arise because of valence-dependent effects on the neural processes recruited during episodic encoding and retrieval, with negative affect associated with increased engagement of sensory processes and positive affect leading to enhanced recruitment of conceptual processes.

    2014-12-01

    Due to Titan's uniquely thick atmosphere and organic haze layers, the most detailed images (with resolution of 300 meters per pixel) of the Saturnian moon's surface exist as Synthetic Aperture Radar (SAR) images taken by Cassini's RADAR instrument. Using the SAR data, we have been putting together detailed geomorphological sketch maps of various Titan regions in an effort to piece together its geologic history. We initially examined the Afekan region of Titan due to extensive SAR coverage. Features described on Afekan fall under the categories (in order of geologic age, extrapolated from their relative emplacement) of hummocky, labyrinthic, plains, and dunes. During our mapping effort, we also divided each terrain category into several different subclasses on a local level. Our map offers a chance to present and analyze the distribution, relationship, and potential formation hypotheses of the different terrains. In bulk, we find evidence for both Aeolian and fluvial processes. A particularly important unit found in the Afekan region is the unit designated "undifferentiated plains", or the "Blandlands" of Titan, a mid-latitude terrain unit comprising 25% of the moon's surface. Undifferentiated plains are notable for its relative featurelessness in radar and infrared. Our interpretation is that it is a fill unit in and around Afekan crater and other hummocky/mountainous units. The plains suggest that the nature of Titan's geomorphology seems to be tied to ongoing erosional forces and sediment deposition. Other datasets used in characterizing Titan's various geomorphological units include information obtained from radiometry, infrared (ISS), and spectrometry (VIMS). We will present the detailed geomorphological sketch map with all the terrain units assigned and labeled.

    2012-12-01

    We present a three-dimensional high-resolution hydrodynamic model for unsteady incompressible flow over an evolving bed topography. This is achieved by using a multilevel Cartesian grid technique that allows the grid to be refined in high-gradient regions and in the vicinity of the river bed. The grid can be locally refined and adapted to the bed geometry, managing the Cartesian grid cells and faces using a hierarchical tree data approach. A ghost-cell immersed-boundary technique is applied to cells intersecting the bed topography. The governing equations have been discretized using a finite-volume method on a staggered grid, conserving second-order accuracy in time and space. The solution advances in time using the fractional step approach. Large-eddy simulation is used as turbulence closure. We validate the model against several experiments and other results from literature. Model results for Stokes flow around a cylinder in the vicinity of a moving wall agree well with Wannier's analytical solution. At higher Reynolds numbers, computed trailing bubble length, separation angle, and drag coefficient compare favorably with experimental and previous computational results. Results for the flow over two- and three-dimensional dunes agree well with published data, including a fair reproduction of recirculation zones, horse-shoe structures, and boiling effects. This shows that the model is suitable for being used as a hydrodynamic submodel in the high-resolution modeling of sediment transport and formation and evolution of subaqueous ripples and dunes.

  8. Detailed Burnup Calculations for Testing Nuclear Data

    NASA Astrophysics Data System (ADS)

    Leszczynski, F.

    2005-05-01

    A general method (MCQ) has been developed by introducing a microscopic burnup scheme that uses the Monte Carlo calculated fluxes and microscopic reaction rates of a complex system and a depletion code for burnup calculations as a basis for solving nuclide material balance equations for each spatial region in which the system is divided. Continuous energy-dependent cross-section libraries and full 3D geometry of the system can be input for the calculations. The resulting predictions for the system at successive burnup time steps are thus based on a calculation route where both geometry and cross sections are accurately represented, without geometry simplifications and with continuous energy data, providing an independent approach for benchmarking other methods and nuclear data of actinides, fission products, and other burnable absorbers. The main advantage of this method over the classical deterministic methods currently used is that the MCQ System is a direct 3D method without the limitations and errors introduced on the homogenization of geometry and condensation of energy of deterministic methods. The Monte Carlo and burnup codes adopted until now are the widely used MCNP and ORIGEN codes, but other codes can be used also. For using this method, there is need of a well-known set of nuclear data for isotopes involved in burnup chains, including burnable poisons, fission products, and actinides. For fixing the data to be included in this set, a study of the present status of nuclear data is performed, as part of the development of the MCQ method. This study begins with a review of the available cross-section data of isotopes involved in burnup chains for power and research nuclear reactors. The main data needs for burnup calculations are neutron cross sections, decay constants, branching ratios, fission energy, and yields. The present work includes results of selected experimental benchmarks and conclusions about the sensitivity of different sets of cross-section data for burnup calculations, using some of the main available evaluated nuclear data files (ENDF-B-VI-Rel.8, JEFF-3.0, JENDL-3.3), on an isotope-by-isotope basis as much as possible. The selected experimental burnup benchmarks are reference cases for LWR and HWR reactors, with analysis of isotopic composition as a function of burnup. For LWR (H2O-moderated uranium oxide lattices) four benchmarks are included: ATM-104 NEA Burnup credit criticality benchmark; Yankee-Rowe Core V; H.B.Robinson Unit 2 and Turkey Point Unit 3. For HWR (D2O-moderated uranium oxide cluster lattices), three benchmarks were selected: NPD-19-rod Fuel Clusters; Pickering-28-rod Fuel Clusters; and Bruce-37-rod Fuel Clusters. The isotopes with experimental concentration data included in these benchmarks are: Se-79, Sr90, Tc99, Ru106, Sn126, Sb125,1129, Cs133-137, Nd143, 145, Sm149-150, 152, Eul53-155, U234-235, 238, Np237, Pu238-242, Am241-243, and Cm242-248. Results and analysis of differences between calculated and measured absolute and/or relative concentrations of these isotopes for the seven benchmarks are included in this work.

    In the present work we characterized samples of plasters and pictorial layers taken from a fresco in the Acireale Cathedral. The fresco represents the Coronation of Saint Venera, patron saint of this Ionian town. By performing a detailed spectroscopic analysis of the plaster preparation layer by Fourier-transform infrared (FTIR) spectroscopy and x-ray diffraction (XRD), and of the painting layer by FTIR and confocal Raman microspectroscopy, scanning electron microscopy+energy dispersive x-ray spectroscopy, and XRD, we were able to identify the pigments and the binders present. In particular, Raman investigation was crucial to the characterization of the pigments thanks to the high resolution of the confocal apparatus used. It is worth stressing that the simultaneous use of complementary techniques was able to provide more complete information for the conservation of the artifact we studied.

    In the present work we characterized samples of plasters and pictorial layers taken from a fresco in the Acireale Cathedral. The fresco represents the Coronation of Saint Venera, patron saint of this Ionian town. By performing a detailed spectroscopic analysis of the plaster preparation layer by Fourier-transform infrared (FTIR) spectroscopy and x-ray diffraction (XRD), and of the painting layer by FTIR and confocal Raman microspectroscopy, scanning electron microscopy+energy dispersive x-ray spectroscopy, and XRD, we were able to identify the pigments and the binders present. In particular, Raman investigation was crucial to the characterization of the pigments thanks to the high resolution of the confocal apparatus used.

  11. How seductive details do their damage: A cognitive theory of interest in science learning

    When interesting irrelevant adjuncts, known as seductive details, are included in a passage, readers are less able to recall structurally important information and are less able to solve problems based on the main ideas in the passage as compared with readers who read the same passage without seductive details. This phenomenon is known as the seductive details effect. To investigate how seductive details interfere with learning a series of four experiments was conducted in which college students read a scientific explanation about the formation of lightning that either contained or did not contain seductive details. The seductive details effect was replicated in each of the 4 experiments. Students who read passages containing seductive details recalled significantly fewer main ideas and generated significantly fewer transfer solutions than students who read the passage with no seductive details. In Experiment 1, students read passages with or without seductive details, and with or without typographical highlighting of the main ideas. Highlighting the main ideas did not reduce the seductive details effect for either the retention of main ideas or for problem-solving performance. In Experiment 2, students read passages with or without seductive details, and with or without a statement of learning objectives prior to reading the passage. Providing learning objectives did not reduce the seductive details effect for retention of main ideas or for problem-solving performance. In Experiment 3, students read passages with or without seductive details, and with or without organizational signaling. Signaling the main ideas in the passage did nd reduce the seductive details effect for retention or for problem-solving performance. In Experiment 4, the placement of the seductive details was varied, such that they were presented before the passage, after the passage, or they were interspersed within the passage. A control group read a passage with no seductive details. Early placement of the seductive details resulted in relatively poor recall and transfer performance, whereas late placement resulted in relatively good recall and transfer performance. Taken together, these results are inconsistent with the distraction hypothesis, i.e., that seductive details distract readers' selection processes, and are inconsistent with the disruption hypothesis, i.e., that seductive details disrupt the coherence of the passage. These results are consistent with the diversion hypothesis, i.e., that seductive details prime an inappropriate context for the reading, by confusing readers as to what a passage is about.

  12. The Devil's Hole Is In The Details

    NASA Astrophysics Data System (ADS)

    Wallace, M. G.

    2012-12-01

    As the granularity of Quaternary paleoclimatic proxy signatures from continental and oceanic sources continues to resolve, increasingly integrated studies such as Shakun et. al. (2012), and Kohfeld and Ridgewell (2009) have emerged, with far-reaching but sometimes conflicting paleo-global climate interpretations. Accordingly, none of the competing empirical and phenomenological narratives regarding the time series of Quaternary temperature patterns fit with sufficient fidelity to the observational record. Among other examples, the Shakun et al. study reviewed and processed 80 proxy sites worldwide for paleotemperature reconstruction, but left out the premier Devil's Hole poxy site in the continental Southwestern U.S. The Devil's Hole site presents a nominally earlier record of an interglacial warming signal (Landwehr and Winograd 2012). Both cite similar data (NOAA, 2005) as confirmation of their competing interpretations. Clearly both cannot be right. Epistemic origins of this apparent conflict may be rooted on the ongoing controversy concerning the importance of orbital forcings to the 100K year Quaternary glacial oscillations. Orbital forcings had been intrinsically posited as the only possible extraterrestrial driver of global temperature cycles over the Quaternary time frame. Yet other extraterrestrial climate forcing parameters are now conceivable. This paper reexamines past 3He marine core measurements conducted on two oceans and two hemispheres, and alternatives to the associated interpretations of researchers Patterson and Farley (1998). This study includes a new phenomenological and empirical exploration of an alternate extraterrestrial Quaternary global climate forcing model. This new interpretation is possible based on improved mapping of the Local Interstellar Medium (ISM), as documented in recent works such as those by Frisch and Mueller (2011).

  13. Turbidity Determination from Broadband Irradiance Measurements: A Detailed Multicoefficient Approach.

    NASA Astrophysics Data System (ADS)

    Gueymard, Christian A.

    1998-04-01

    A physically modeled method is presented to obtain accurate turbidity determinations from broadband direct irradiance measurements. The method uses parameterizations of various extinction processes affecting the transfer of shortwave radiation in a cloudless atmosphere. The integration over the shortwave solar spectrum is performed with a more realistic weighting function than is conventionally used. The calculation and properties of the broadband aerosol optical depth are discussed in detail as a function of the aerosol optical characteristics. The method is general, as it can predict any one of the four turbidity coefficients currently used in climatological studies as defined by Ångström, Linke, Unsworth-Monteith, and Schüepp. Formal interrelationships are proposed so that climatological data based on different coefficients can be consistently intercompared without recourse to empirical formulas. The new parameterizations are more detailed than those of the literature, particularly regarding the optical depth of the clean dry atmosphere that now depends explicitly on the stratospheric ozone and nitrogen dioxide amounts. This inevitably induces changes in the prediction of the broadband turbidity coefficients (Linke and Unsworth-Monteith), particularly at small zenith angles when compared to older calculations. These coefficients are also shown to depend on zenith angle and precipitable water, causing parasitic variations of turbidity during a day or the year even if the aerosol characteristics do not vary. The masking effect of tropospheric nitrogen dioxide is presented, as well as a method to correct the predicted turbidity for circumsolar radiation. A detailed error analysis is discussed, showing that the instrumental error and the estimation error on precipitable water are the main limiting factors of the method. Although smaller potential error is obtained at larger zenith angles, accurate estimates of precipitable water are necessary for valid turbidity predictions when applied to clean dry atmospheres. A limited test of the method is presented, using spectral radiative data from five different sites as the reference. The method performs well, provided that accurate precipitable water data can be obtained. In contrast, the older Louche's method is shown to produce unrealistic negative values under clean dry conditions. Monthly average turbidity over 3-4 years was also obtained from hourly irradiance at two sites with widely different aerosol regimes. Compared to the present results, Louche's method is found to overpredict the Unsworth-Monteith coefficient at both sites, while simultaneously underpredicting the Ångström coefficient at the clearest site.

  14. Detailed Study of Ozone Response to Large SEP Events

    Solar Energetic particle (SEP) events, in particular Solar Proton Events (SPEs), have been shown to affect chemical balance of the middle atmosphere (in particular, from 60 to 90 km in altitude). Energetic protons of energies above 1 MeV penetrate into the middle atmosphere and temporarily increase production of chemically active odd hydrogen species (HOx) which in turn causes ozone (O3) destruction. However, many questions remain as to how the detailed HOx-O3 chemical system responds to various types of SEPs, i.e., gradual or impulsive, or to different characteristics of SEP events. The Microwave Limb Sounder (MLS) launched on board Aura satellite in 2004 provides daily simultaneous measurements of HOx, O3 and related parameters such as H2O and temperature on a global scale during both day and night. This is the first time that global measurements of both odd hydrogen species (OH and HO2) are made simultaneously on a daily basis. We will present first results of detailed analysis of several large SEP events in 2004-2006 and corresponding middle atmospheric signatures. We will demonstrate enhancements in nighttime odd hydrogen and ozone densities concomitant with the SEP events. For a detailed study we will use GOES and ACE observations in combination with MLS/Aura measurements to evaluate factors determining nighttime OH and O3 responses to SEP events, such as strength and duration of an SEP event, its spectrum and phenomenology. We will discuss the main contributing factors and characterize odd oxygen and hydroxyl response to large SEP events.

  15. A data-management system for detailed areal interpretive data

    USGS Publications Warehouse

    Ferrigno, C.F.

    1986-01-01

    A data storage and retrieval system has been developed to organize and preserve areal interpretive data. This system can be used by any study where there is a need to store areal interpretive data that generally is presented in map form. This system provides the capability to grid areal interpretive data for input to groundwater flow models at any spacing and orientation. The data storage and retrieval system is designed to be used for studies that cover small areas such as counties. The system is built around a hierarchically structured data base consisting of related latitude-longitude blocks. The information in the data base can be stored at different levels of detail, with the finest detail being a block of 6 sec of latitude by 6 sec of longitude (approximately 0.01 sq mi). This system was implemented on a mainframe computer using a hierarchical data base management system. The computer programs are written in Fortran IV and PL/1. The design and capabilities of the data storage and retrieval system, and the computer programs that are used to implement the system are described. Supplemental sections contain the data dictionary, user documentation of the data-system software, changes that would need to be made to use this system for other studies, and information on the computer software tape.

    Bax and Bid are pro-apoptotic members of the Bcl-2 protein family. Upon cleavage by caspase-8, Bid activates Bax. Activated Bax inserts into the mitochondrial outer membrane forming oligomers which lead to membrane poration, release of cytochrome c, and apoptosis. The detailed mechanism of Bax activation and the topology and composition of the oligomers are still under debate. Here molecular details of Bax activation and oligomerization were obtained by application of several biophysical techniques, including atomic force microscopy, cryoelectron microscopy, and particularly electron paramagnetic resonance (EPR) spectroscopy performed on spin-labeled Bax. Incubation with detergents, reconstitution, and Bid-triggered insertion into liposomes were found to be effective in inducing Bax oligomerization. Bid was shown to activate Bax independently of the stoichiometric ratio, suggesting that Bid has a catalytic function and that the interaction with Bax is transient. The formation of a stable dimerization interface involving two Bcl-2 homology 3 (BH3) domains was found to be the nucleation event for Bax homo-oligomerization. Based on intermolecular distance determined by EPR, a model of six adjacent Bax molecules in the oligomer is presented where the hydrophobic hairpins (helices α5 and α6) are equally spaced in the membrane and the two BH3 domains are in close vicinity in the dimer interface, separated by >5 nm from the next BH3 pairs.

    2014-01-01

    Background and objective Intermountain Healthcare has a long history of using coded terminology and detailed clinical models (DCMs) to govern storage of clinical data to facilitate decision support and semantic interoperability. The latest iteration of DCMs at Intermountain is called the clinical element model (CEM). We describe the lessons learned from our CEM efforts with regard to subjective decisions a modeler frequently needs to make in creating a CEM. We present insights and guidelines, but also describe situations in which use cases conflict with the guidelines. We propose strategies that can help reconcile the conflicts. The hope is that these lessons will be helpful to others who are developing and maintaining DCMs in order to promote sharing and interoperability. Methods We have used the Clinical Element Modeling Language (CEML) to author approximately 5000 CEMs. Results Based on our experience, we have formulated guidelines to lead our modelers through the subjective decisions they need to make when authoring models. Reported here are guidelines regarding precoordination/postcoordination, dividing content between the model and the terminology, modeling logical attributes, and creating iso-semantic models. We place our lessons in context, exploring the potential benefits of an implementation layer, an iso-semantic modeling framework, and ontologic technologies. Conclusions We assert that detailed clinical models can advance interoperability and sharing, and that our guidelines, an implementation layer, and an iso-semantic framework will support our progress toward that goal.

  7. A Comparison of Detailed Level and Superconfiguration Models of Neon

    SciTech Connect

    Hansen, S B; Fournier, K B; Bauche-Arnoult, C; Bauche, J; Peyrusse, O

    2005-01-03

    The superconfiguration (SC) approach to collisional-radiative modeling can significantly decrease the computational demands of finding non-LTE level populations in complex systems. However, it has not yet been fully determined whether the statistical averaging of SC models leads to a significant loss of accuracy. The present work compares results from two independent models: a detailed-level accounting (DLA) model based on HULLAC data and the SC model MOST. The relatively simple level structures of the K- and L-shell ions of the neon test system ensure a tractable number of levels in the DLA model but challenge the statistical assumptions of the SC approach. Nonetheless, we find fair agreement between the two models for average ion charges, SC populations, and various effective temperatures.

  8. Detailed characteristics of intermittent current pulses due to positive corona

    SciTech Connect

    Liu, Yang Cui, Xiang; Lu, Tiebing; Wang, Zhenguo; Li, Xuebao; Xiang, Yu; Wang, Xiaobo

    2014-08-15

    In order to get detailed characteristics of intermittent current pulses due to positive corona such as the repetition rate of burst-pulse trains, the peak value ratio of the primary pulse to the secondary pulse, the number of pulses per burst, and the interval of the secondary pulses, a systematic study was carried out in a coaxial conductor-cylinder electrode system with the conductor electrode being set with a discharge point. Empirical formulae for the number of pulses per burst and the interval of the secondary pulses are first presented. A theoretical model based on the motion of the space-charge clouds is proposed. Analysis with the model gives explanations to the experimental results and reveals some new insights into the physical mechanism of positive intermittent corona.

  9. A Detailed Spectroscopic Analysis of The EQ Pegasi System

    NASA Astrophysics Data System (ADS)

    Schlieder, Joshua E.; Murphy, Simon; Riedel, Adric R.

    2015-01-01

    EQ Pegasi (GJ 896, HIP 116132 ) is a resolved binary system comprised of mid-M dwarfs at a distance of only 6.2 pc. The system has been studied extensively over a broad range of wavelengths from the X-ray to the radio. These observations reveal both components are variable, flare, and exhibit high levels of magnetic activity. The pair were recently proposed as members of a nearby young kinematic association on the basis of consistent Galactic kinematics, strong X-ray emission, and color-magnitude diagram position. Thus, they may be the closest pre-main-sequence system to the Sun. Here we present a detailed analysis of EQ Peg A and B using medium resolution spectra covering ~0.5-2.5 microns. We investigate spectral types, chromospheric activity indicators, lithium depletion, and gravity sensitive alkali lines and molecular bands to characterize the system and place constraints on its age.

    1980-01-01

    A single stage fan and quarter stage booster were designed for the energy efficient engine. The fan has an inlet radius ratio of 0.342 and a specific flow rate of 208.9 Kg/S sq m (42.8 lbm/sec sq ft). The fan rotor has 32 medium aspect ratio (2.597) titanium blades with a partspan shroud at 55% blade height. The design corrected fan tip speed is 411.5 M/S (1350 ft/sec). The quarter stage island splits the total fan flow with approximately 22% of the flow being supercharged by the quarter stage rotor. The fan bypass ratio is 6.8. The core flow total pressure ratio is 1.67 and the fan bypass pressure ratio is 1.65. The design details of the fan and booster blading, and the fan frame and static structure for the fan configuration are presented.

  12. Detailed modeling of three-dimensional chemical vapor deposition

    NASA Astrophysics Data System (ADS)

    Ern, Alexandre; Giovangigli, Vincent; Smooke, Mitchell D.

    1997-10-01

    In this paper we investigate computationally a metalorganic chemical vapor deposition reactor. Our model combines a three-dimensional solution of the coupled Navier-Stokes/energy equations in a vorticity-velocity form, new and accurate multicomponent transport algorithms, and detailed finite rate chemistry in the gas phase and on the crystal surface. We apply a modified Newton method along with efficient Jacobian evaluation and linear algebra procedures in order to obtain a numerical solution. The present study focuses primarily on film uniformity and carbon incorporation levels. Our numerical results show the critical importance of transport modeling for an accurate description of the growth process. Furthermore, three growth regimes arise as a function of susceptor temperature: a kinetics-controlled regime at low temperatures, a diffusion-controlled regime at intermediate temperatures, and a desorption-controlled regime at high temperatures. These results are further supported by a sensitivity analysis with respect to both gas phase and surface chemistry.

  13. Near Real-Time Call Detail Record ETL Flows

    NASA Astrophysics Data System (ADS)

    Cochinwala, Munir; Panagos, Euthimios

    Telecommunication companies face significant business challenges as they strive to reduce subscriber churn and increase average revenue per user (ARPU) by offering new services and incorporating new functionality into existing services. The increased number of service offerings and available functionality result in an ever growing volume of call detail records (CDRs). For many services (e.g., pre-paid), CDRs need to be processed and analyzed in near real-time for several reasons, including charging, on-line subscriber access to their accounts, and analytics for predicting subscriber usage and preventing fraudulent activity. In this paper, we describe the challenges associated with near real-time extract, transform, and load (ETL) of CDR data warehouse flows for supporting both the operational and business intelligence needs of telecommunication services, and we present our approach to addressing these challenges.

  14. Detailed drive balance for NTMs on the MAST tokamak

    NASA Astrophysics Data System (ADS)

    Snape, Jack; Gibson, Kieran; O'Gorman, Thomas; Wilson, Howard; MAST Team

    2011-10-01

    The neoclassical tearing mode (NTM) is a performance limiting instability for tokamaks. Though well established, many uncertainties remain in the modified Rutherford equation for NTM evolution. We build on previous work,, focussing on 2/1 NTMs (the most detrimental) and making use of a large suite of diagnostics, including upgraded Thomson scattering and charge exchange systems. Novel diagnostic triggering techniques are used to capture temperature and density profiles at specific NTM phases and amplitudes. Using this data as an input for the Fitzpatrick transport model we directly measure the transport threshold width, usually obtained by a simple heuristic formula. We extend this model to include the asymmetric nature of the NTMs that are observed on MAST. We combine these measurements with information from equilibrium codes and present a detailed drive balance calculation to determine the relative significance of different terms in the Rutherford equation.

    We present newly derived stellar parameters and the detailed abundances of 19 elements of seven stars with small planets discovered by NASA's Kepler Mission. Each star save one has at least one planet with a radius less than 2 REarth, suggesting a primarily rocky composition. The stellar parameters and abundances are derived from high signal-to-noise ratio, high-resolution echelle spectroscopy obtained with the 10-m Keck I telescope and HIRES spectrometer using standard spectroscopic techniques. We compare the abundances to those of a general Galactic disk population and investigate possible abundance trends with condensation temperature of the elements.S.C.S. acknowledges support provided by grant NNX12AD19G to S.C.S. from the National Aeronautics and Space Administration as part of the Kepler Participating Scientist Program.

    2008-09-01

    Creations of brain are called intellect. Since these creations have good commercial value, are called as property. Inventions are intellectual property and can be protected by patents provided the invention is novel, non-obvious, useful and enabled. To have fare trade among member countries, World Trade Organisation proposed TRIPS agreement. India had taken necessary initiation by signing the World Trade Organisation agreement and transformed to global needs. The aim of this article is to enlighten pharmaceutical professionals especially in the field of research and development about planning inventions by thorough review of prior-art, which saves time and money. A thorough understanding is made possible by providing details of origin; present governing bodies, their role along with the Act that is safeguarding the patent system. PMID:21394248

  17. Detailed modeling of cluster galaxies in free-form lenses

    NASA Astrophysics Data System (ADS)

    Lam, Daniel

    2015-08-01

    The main goal of the Frontier Fields is to characterize the population of high redshift galaxies that are gravitationally lensed and magnified by foreground massive galaxy clusters. The magnification received by lensed images has to be accurately quantified in order to derive the correct science results. The magnification is in turn computed from lens models, which are constructed from various constraints, most commonly the positions and redshifts of multiply-lensed galaxies.The locations and magnification of multiple images that appear near cluster galaxies are very sensitive to the mass distribution of those individual galaxies. In current free-form lens models, they are at best crudely approximated by arbitrary mass halos and are usually being completely neglected. Given sufficient free parameters and iterations, such models may be highly consistent but their predictive power would be rather limited. This shortcoming is particularly pronounced in light of the recent discovery of the first multiply-lensed supernova in the Frontier Fields cluster MACSJ1149. The proximity of its images to cluster galaxies mandates detailed modeling on galaxy-scales, where free-form methods solely based on grid solutions simply fail.We present a hybrid free-form lens model of Abell 2744, which for the first time incorporates a detailed mass component modeled by GALFIT that accurately captures the stellar light distribution of the hundred brightest cluster galaxies. The model better reproduces the image positions than a previous version, which modeled cluster galaxies with simplistic NFW halos. Curiously, this improvement is found in all but system 2, which has two radial images appearing around the BCG. Despite its complex light profile is being captured by GALFIT, the persistent discrepancies suggest considering mass distributions that may be largely offset from the stellar light distribution.

  19. Extrapulmonary presentation of sarcoidosis.

    PubMed

    Rizzato, G

    2001-09-01

    Sarcoidosis is a systemic disease that usually has a pulmonary presentation. Extrapulmonary presentation of the disease is often unrecognized because the clinical signs ( eg, peripheral lymph nodes) and more important symptoms ( eg, renal stones or uveitis) do not usually indicate systemic disease. In three different long-term studies of patients with sarcoidosis, 1.5% of the patients presented with uveitis, 11.7% presented with peripheral lymph nodes, and 3.6% presented with renal stones; a total of 16.6% of the patients had extrapulmonary presentation of sarcoidosis. Two of the three studies were retrospective. Many patients may have skin, parotid gland, spleen, liver, central nervous system, bone, or heart presentation; 16.6% is only the tip of an iceberg. A well-conducted, prospective, long-term study could indicate that more than 30% of patients with sarcoidosis have extrapulmonary presentations of the disease. PMID:11584179

  6. Detailed mechanism of toluene oxidation and comparison with benzene

    NASA Technical Reports Server (NTRS)

    Bittker, David A.

    1988-01-01

    A detailed mechanism for the oxidation of toluene in both argon and nitrogen dilutents is presented. The mechanism was used to compute experimentally ignition delay times for shock-heated toluene-oxygen-argon mixtures with resonably good success over a wide range of initial temperatures and pressures. Attempts to compute experimentally measured concentration profiles for toluene oxidation in a turbulent reactor were partially successful. An extensive sensitivity analysis was performed to determine the reactions which control the ignition process and the rates of formation and destruction of various species. The most important step was found to be the reaction of toluene with molecular oxygen, followed by the reactions of hydroperoxyl and atomic oxygen with benzyl radicals. These findings contrast with the benzene oxidation, where the benzene-molecular oxygen reaction is quite unimportant and the reaction of phenyl with molecular oxygen dominates. In the toluene mechanism the corresponding reaction of benzyl radicals with oxygen is unimportant. Two reactions which are important in the oxidation of benzene also influence the oxidation of toluene for several conditions. These are the oxidations of phenyl and cyclopentadienyl radicals by molecular oxygen. The mechanism presented successfully computes the decrease of toluene concentration with time in the nitrogen diluted turbulent reactor. This fact, in addition to the good prediction of ignition delay times, shows that this mechanism can be used for modeling the ignition and combustion process in practical, well-mixed combustion systems.

  7. A thermoacoustic-Stirling heat engine: Detailed study

    SciTech Connect

    Backhaus, S.; Swift, G. W.

    2000-06-01

    A new type of thermoacoustic engine based on traveling waves and ideally reversible heat transfer is described. Measurements and analysis of its performance are presented. This new engine outperforms previous thermoacoustic engines, which are based on standing waves and intrinsically irreversible heat transfer, by more than 50%. At its most efficient operating point, it delivers 710 W of acoustic power to its resonator with a thermal efficiency of 0.30, corresponding to 41% of the Carnot efficiency. At its most powerful operating point, it delivers 890 W to its resonator with a thermal efficiency of 0.22. The efficiency of this engine can be degraded by two types of acoustic streaming. These are suppressed by appropriate tapering of crucial surfaces in the engine and by using additional nonlinearity to induce an opposing time-averaged pressure difference. Data are presented which show the nearly complete elimination of the streaming convective heat loads. Analysis of these and other irreversibilities show which components of the engine require further research to achieve higher efficiency. Additionally, these data show that the dynamics and acoustic power flows are well understood, but the details of the streaming suppression and associated heat convection are only qualitatively understood.

    Rai, Durgesh; Anunciado, Divina; Heller, William; O'Neill, Hugh; Urban, Volker; Qian, Shuo

    2015-03-01

    Alzheimer's disease (AD) is the most common form of dementia and is predicted to affect 1 in 85 people around the world by 2050. Amyloid beta (A β) -peptide, a peptide composed of 40- 42 amino acids that is the product of cleavage from the amyloid precursor protein (APP), is regarded to play a major role in the development of AD. In addition, accumulating evidence points to a positive association between cholesterol and AD. Here, we present results from our studies about A β-peptide and cholesterol in bilayer by small-angle neutron scattering (SANS) using a combination of dimyristoyl, phosphocholine (DMPC) and partially deuterated cholesterol (cholesterol-d7) with and without A β. We compare the results using grazing incidence and transmission SANS on lipid bilayer films and unilamellar vesicles respectively. The structural details on vesicles and bilayers work in conjunction with the circular dichroism on peptide in solution and oriented circular dichroism in bilayer films. The studies confirm a positive association of A β with the membrane layers. The results from different studies will be compared and contrasted in presentation.

    2013-09-01

    This review paper discusses the concept of level of detail in 3D city modelling, and is a first step towards a foundation for a standardised definition. As an introduction, a few level of detail specifications, outlooks and approaches are given from the industry. The paper analyses the general uncertainties and shortcomings around the concept of level of detail in 3D city modelling such as ordinality and inconsistencies, and identifies factors that constitute a specific level of detail. The paper proposes a framework for a new consistent LoD definition which would consolidate present and future LoD paradigms, gives an example of an LoD specification, discusses open questions such as the contexts for which 3D city models are used in practice, and gives prospects for a future quantification and sorting of levels of detail.

    2008-01-01

    Aims and Objectives: Delayed management of anorectal malformation (ARM) increases the surgical and functional complications for the patient. We defined “delayed presentation of ARM” and reviewed our patients with ARM to find out the incidence and causes of delayed presentation. Materials and Methods: Patients satisfying the criteria of “delayed presentation of ARM” were involved. Detailed information of each patient including the mode of presentation, associated anomalies, plan of management and follow-up was obtained from the hospital records. Results: Between 2003 and 2006, 43 patients satisfied our criteria of “delayed presentation of ARM”. There were 21 males and 22 females. Seventeen of these males presented with low-type ARM. Eleven of them were managed by a single-stage procedure. These “delayed presenters” had to live with constipation, inadequate weight gain and parental anxiety for a greater time. Analysis of the outcomes showed more functional complications in patients who had undergone failed perineal surgery previously. In females with low ARM, the procedure of choice was anterior sagittal anorectoplasty (ASARP). Single stage surgery provides good outcomes for most of low type of ARMs. High-type ARMs in males and females were managed by a staged procedure. Conclusion: “Delayed presentation of ARM” is a major group of ARM in our setup. The management and results of their treatment are not different from those of the early presenters. The most common cause of delayed ARM is wrong advice given by the health care providers followed by inadequate treatment elsewhere. Corrective surgeries taking second attempt in perineum always produces poor outcomes. PMID:20011470

    2009-12-01

    The interpretation of volcanic eruptions is usually derived from direct observation and the thorough analysis of the deposits. Processes in vent-proximal areas are usually not directly accessible or likely to be obscured. Hence, our understanding of proximal deposits is often limited as they were produced by the simultaneous events stemming from primary eruptive, transportative, and meteorological conditions. Here we present a method that permits for a direct and detailed quasi in-situ investigation of loose pyroclastic units that are usually analysed in the laboratory for their 1) grain-size distribution, 2) componentry, and 3) grain morphology. As the clast assembly is altered during sampling, the genesis of a stratigraphic unit and the relative importance of the above mentioned deposit characteristics is hard to achieve. In an attempt to overcome the possible loss of information during conventional sampling techniques, we impregnated the cleaned surfaces of proximal, unconsolidated units of the 1957-58 Capelinhos eruption on Faial, Azores. During this basaltic, emergent eruption, fluxes in magma rise rate led to a repeated build-up and collapse of tuff cones and consequently to a shift between phreatomagmatic and magmatic eruptive style. The deposits are a succession of generally parallel bedded, cm- to dm-thick layers with a predominantly ashy matrix. The lapilli content is varying gradually; the content of bombs is enriched in discrete layers without clear bomb sags. The sample areas have been cleaned and impregnated with a two-component glue (EPOTEK 301). For approx. 10 * 10 cm, a volume of mixed glue of 20 ml was required. This low-viscosity, transparent glue allowed for an easy application on the target area by means of a syringe and permeated the deposit as deep as 5 mm. After > 24 h, the glue was sufficiently dry to enable the sample to be laid open. This impregnation method renders it possible to cut and polish the sample and investigate grain-size distribution, componentry, and grain morphology in situ in a 2D-plane. In a first step, the sample surface has been scanned and analysed by means of image analysis software (Image J). After that, selected areas were investigated through thin section analysis. We were able to define depositional units in the (sub)-mm scale and the show the varying relative importance of 1) eruptive style, 2) transportation mode, and 3) the influence of wind and (air) humidity. The presented method is an easy and efficient tool for a detailed stratigraphic investigation of unconsolidated pyroclastic units.

    The interpretation of volcanic eruptions is usually derived from direct observation and the thorough analysis of the deposits. Processes in vent-proximal areas are usually not directly accessible or likely to be obscured. Hence, our understanding of proximal deposits is often limited as they were produced by the simultaneous events stemming from primary eruptive, transportative, and meteorological conditions. Here we present a method that permits for a direct and detailed quasi in-situ investigation of loose pyroclastic units that are usually analysed in the laboratory for their 1) grain-size distribution, 2) componentry, and 3) grain morphology.

    Presentism is generally regarded as a necessary evil in historiography. This paper explores the upside of that inevitability. Using a philosophical approach to discourse analysis in the tradition of new cultural history, the paper distinguishes between a strategic use of presentism on the one hand, and a rationalistic approach to history on the…
