Animated PowerPoint presentations: Help or Hindrance?  

NASA Astrophysics Data System (ADS)

It is common practice to use PowerPoint presentations as the primary method of lecturing. PowerPoint has a number of useful features that can aid in the delivery of lesson material, the most common being the animation of PowerPoint slides. While anecdotal evidence suggests that PowerPoint animations aid in the presentation of lesson material, does it aid in student learning, or is it simply a distraction to the students? A recent study of an Introductory Management of Information Systems class (Mahar et al. 2009) suggests that the latter may be the case, but the authors acknowledge that their results may be subject dependent. We will discuss preliminary results of a study to determine if the inclusion of basic animation techniques provides an additional learning aid to students in an introductory astronomy course, or if in fact it inhibits learning. We will present our analysis of data obtained from two sections of our introductory Stars & Galaxies course. The material in both classes was alternately introduced via PowerPoint either with or without animations (in this case, "animated" refers to material being incrementally presented one line at a time on a slide, as opposed to everything appearing all at once.). We will address not only a comparison of the level of student understanding achieved via both methods of instruction, but also student perception of the usefulness of the animations. We will also discuss further plans to investigate the effect of more advanced animations, such as the animation of figures in order to convey motion or progression.

Hawaii's "7 by 7" for school health education: a PowerPoint presentation on integrating the national health education standards with priority content areas for today's school health education in grades kindergarten through 12.  

PubMed

School-based health education can help young people develop the knowledge, skills, motivation, and support they need to choose health-enhancing behaviors and resist engaging in behaviors that put them at risk for health and social problems and school failure. The health of school-age youth is significantly associated with their school achievement. However, in the midst of today's increased emphasis on school accountability in the areas of reading, writing, and mathematics, subject areas such as health education tend to receive less prominence in the school curriculum. Recalling their own lackluster school experiences related to health topics, decision makers may not realize that today's skills-based school health curriculum involves a highly interactive and engaging approach to promoting good health and preventing the most serious health problems among youth. Health education is one important component of a coordinated school health program that includes health education, physical education, school health services, nutrition services, school counseling and psychological services, a healthy school environment, school promotion for faculty and staff, and involvement of family and community members. The purpose of this PowerPoint presentation--Healthy Keiki, Healthy Hawaii: Hawaii's "7 by 7" for School Health Education--is to educate health and education decision makers, teachers, parents, and community members on how Hawaii has integrated seven health education standards with seven priority health content areas to create an effective approach to school health education in grades kindergarten through 12. The goal of Hawaii's "7 by 7" curriculum focus is to ensure that all of Hawaii's keiki (children) have well-planned opportunities at school to become fit, healthy, and ready to learn. PMID:16539804

Using Keynote to present radiology images.  

PubMed

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

The objective is to provide original unlabeled as well as labeled sections of the human body of high quality and resolution on the Internet, for use in basic and continuing medical education. For a representative overview of the body, 370 axial sections were selected from the male and female data base of the VHP with special regard to regions of clinical interest. Each section is accompanied by its corresponding computer tomography (CT) image and, if available, magnetic resonance images (MRI) for quick and easy comparison of morphologic and radiologic structures. The sections can be studied unlabeled or labeled according to the current Terminologia Anatomica. A linked vocabulary with more than 850 terms explains the labeling. Animations of the sections as well as of CT and MR images allow for further visualization of the topographic relationships of anatomical structures. The responses to the project indicate that students and physicians regard the Internet Atlas of Human Gross Anatomy as a most useful aid for learning and reviewing anatomical details. The atlas is accessible on: http://www.uni-mainz.de/FB/Medizin/Anatomie/workshop/vishuman/Eready.html. PMID:12373730

Physicists in Primary Schools (PIPS) Project: Fun Presentations for Physicists to Take into Schools Worldwide (abstract)  

NASA Astrophysics Data System (ADS)

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.

Academic detailing.  

PubMed

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

Complex Management of a Patient with a Contiguous Xp11.4 Gene Deletion Involving Ornithine Transcarbamylase: A Role for Detailed Molecular Analysis in Complex Presentations of Classical Diseases  

PubMed Central

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.

New Methods of Presenting Scale the Universe Concepts  

NASA Astrophysics Data System (ADS)

Traditional scale of the universe activities involve building a scale model solar system, expressing distances in light travel time, and doing powers-of-ten animations. Free NASA materials will provide a sorting/ordering activity to teach this concept in a different way and at the same time introduce vocabulary and concepts involving some of the most distant objects in the universe. In addition, the author has used two novel methods of teaching universe scaling concepts: using a video of a drive representing the distance to a nearby star translates the distance concept into a more personal time-based experience, and a new version of a scale the universe powerpoint that uses power-of-1000 slides to compress each view of the universe into a single pixel of the next slide to help visualize the vast scales encompassing the universe and how far humanity's influence actually extends.

Effective Presentations  

PubMed Central

Where the purpose of presentations is to inform, effective delivery is important to ensure that audiences receive the educational message. We offer six suggestions: introduce the topic in an interesting way; speak loudly enough; do not read; involve the audience actively; respect the attention span of the audience; and limit the amount of content. We conclude that the skills of live public presentation can be learned, but that the art of presentation is innate. Imagesp2063-ap2064-a

Detailed Debunking of Denial  

NASA Astrophysics Data System (ADS)

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.

Comment: Detailed balance revisited.  

PubMed

The concept of detailed balance is central to the field of chemical kinetics and provides important constraints on relationships between equilibrium and rate constants. Miller et al. [Phys. Chem. Chem. Phys., 2009, 11, 1128] have recently proposed that having the ratio of forward and reverse rate constants equal to the equilibrium constant--a relationship they equate with detailed balance--is a sufficient condition to guarantee that a chemical system eventually relaxes to equilibrium. This assertion is true, however, only for an isolated system. In a closed system, where energy exchange between the system and the environment occurs, input of energy in the form of an externally driven oscillation of a thermodynamic parameter (e.g. pressure or electric field strength), can maintain a chemical system in a stationary state away from equilibrium even if the ratio of the forward and backward rate constants for each elementary reaction equals the equilibrium constant at every instant. This fact allows appropriately designed molecules to serve as free-energy transducers and molecular machines. PMID:19830346

Route visualization using detail lenses.  

PubMed

We present a method designed to address some limitations of typical route map displays of driving directions. The main goal of our system is to generate a printable version of a route map that shows the overview and detail views of the route within a single, consistent visual frame. Our proposed visualization provides a more intuitive spatial context than a simple list of turns. We present a novel multifocus technique to achieve this goal, where the foci are defined by points of interest (POI) along the route. A detail lens that encapsulates the POI at a finer geospatial scale is created for each focus. The lenses are laid out on the map to avoid occlusion with the route and each other, and to optimally utilize the free space around the route. We define a set of layout metrics to evaluate the quality of a lens layout for a given route map visualization. We compare standard lens layout methods to our proposed method and demonstrate the effectiveness of our method in generating aesthetically pleasing layouts. Finally, we perform a user study to evaluate the effectiveness of our layout choices. PMID:20075484

Influences on physicians' adoption of electronic detailing (e-detailing).  

PubMed

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

Engaging the Audience: Developing Presentation Skills in Science Students  

PubMed Central

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.

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

NASA Astrophysics Data System (ADS)

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,1 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.

Detailing the human tail.  

PubMed

There have been 23 true vestigial tails reported in the literature since 1884. A new case is described, and its magnetic resonance imaging and pathological features are presented. A review of the literature and analysis of the pathological characteristics reveal that the vestigial human tail may be associated with other abnormalities. Vestigial tails contain adipose and connective tissue, blood vessels, and nerves and are covered by skin. Bone, cartilage, notochord, and spinal cord elements are lacking. Tails are easily removed surgically without residual effects. Since 29% (7 of 24) of the reported tails have been associated with other malformations, careful clinical evaluation of these patients is recommended. PMID:3284435

Public speaking: creating presentations that are awe inspiring not yawn producing.

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

Recognition of detail in mammography  

NASA Astrophysics Data System (ADS)

In radiological practice the term recognition of detail is widely used. We examined how the term can be defined and interpreted, and how recognition of detail relates to radiological phantoms such as CDMAM (Contrast Detail Mammography). For tasks in visual perception a processing hierarchy can be assumed: The perception of a structure can occur at different processing levels, such as required in detection, discrimination, identification and recognition, with an ascending order of hierarchical relation. It is not always possible to predict from results at one hierarchy level those at another level. If an observer detects a structure, there is no prediction whether the observer will be able to discriminate the structure from another or whether he or she is even able to interpret the structure. Furthermore, the perceptibility of a detail is influenced by surrounding or overlapping anatomical noise. The presence of noise elevates visual thresholds and may change the overall perceptual behavior with regard to the examined parameter. Thus, perceptibility of structures (details) is strongly bound to the type of perceptual task and the image background used. Speaking of recognition of detail should not liberally extended to evaluating performance parameters of a technical system. If the term is applied, it needs to be specified how detail is characterized and which perceptual task is used for operationalizing recognition.

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

NASA Astrophysics Data System (ADS)

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.

NOSS Altimeter Detailed Algorithm specifications  

NASA Technical Reports Server (NTRS)

The details of the algorithms and data sets required for satellite radar altimeter data processing are documented in a form suitable for (1) development of the benchmark software and (2) coding the operational software. The algorithms reported in detail are those established for altimeter processing. The algorithms which required some additional development before documenting for production were only scoped. The algorithms are divided into two levels of processing. The first level converts the data to engineering units and applies corrections for instrument variations. The second level provides geophysical measurements derived from altimeter parameters for oceanographic users.

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

PubMed

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.

Detailed Studies of Electron Cooling Friction Force  

SciTech Connect

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 VORPAL 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.

Making your presentation fun: creative presentation techniques  

SciTech Connect

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.

Implementation details of the coupled QMR algorithm  

NASA Technical Reports Server (NTRS)

The original quasi-minimal residual method (QMR) relies on the three-term look-ahead Lanczos process, to generate basis vectors for the underlying Krylov subspaces. However, empirical observations indicate that, in finite precision arithmetic, three-term vector recurrences are less robust than mathematically equivalent coupled two-term recurrences. Therefore, we recently proposed a new implementation of the QMR method based on a coupled two-term look-ahead Lanczos procedure. In this paper, we describe implementation details of this coupled QMR algorithm, and we present results of numerical experiments.

Detailed fuel spray analysis techniques  

NASA Technical Reports Server (NTRS)

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.

The Finer Details: Climate Modeling  

NASA Technical Reports Server (NTRS)

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.

Detailed mechanism for oxidation of benzene  

NASA Technical Reports Server (NTRS)

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.

Picornavirus uncoating intermediate captured in atomic detail  

PubMed Central

It remains largely mysterious how the genomes of non-enveloped eukaryotic viruses are transferred across a membrane into the host cell. Picornaviruses are simple models for such viruses, and initiate this uncoating process through particle expansion, which reveals channels through which internal capsid proteins and the viral genome presumably exit the particle, although this has not been clearly seen until now. Here we present the atomic structure of an uncoating intermediate for the major human picornavirus pathogen CAV16, which reveals VP1 partly extruded from the capsid, poised to embed in the host membrane. Together with previous low-resolution results, we are able to propose a detailed hypothesis for the ordered egress of the internal proteins, using two distinct sets of channels through the capsid, and suggest a structural link to the condensed RNA within the particle, which may be involved in triggering RNA release.

Present-day plate motions  

NASA Technical Reports Server (NTRS)

A data set comprising 110 spreading rates, 78 transform fault azimuths and 142 earthquake slip vectors was inverted to yield a new instantaneous plate motion model, designated RM2. The mean averaging interval for the relative motion data was reduced to less than 3 My. A detailed comparison of RM2 with angular velocity vectors which best fit the data along individual plate boundaries indicates that RM2 performs close to optimally in most regions, with several notable exceptions. On the other hand, a previous estimate (RM1) failed to satisfy an extensive set of new data collected in the South Atlantic Ocean. It is shown that RM1 incorrectly predicts the plate kinematics in the South Atlantic because the presently available data are inconsistent with the plate geometry assumed in deriving RM1. It is demonstrated that this inconsistency can be remedied by postulating the existence of internal deformation with the Indian plate, although alternate explanations are possible.

Devil in the details? Developmental dyslexia and visual long-term memory for details  

PubMed Central

Cognitive theories on causes of developmental dyslexia can be divided into language-specific and general accounts. While the former assume that words are special in that associated processing problems are rooted in language-related cognition (e.g., phonology) deficits, the latter propose that dyslexia is rather rooted in a general impairment of cognitive (e.g., visual and/or auditory) processing streams. In the present study, we examined to what extent dyslexia (typically characterized by poor orthographic representations) may be associated with a general deficit in visual long-term memory (LTM) for details. We compared object- and detail-related visual LTM performance (and phonological skills) between dyslexic primary school children and IQ-, age-, and gender-matched controls. The results revealed that while the overall amount of LTM errors was comparable between groups, dyslexic children exhibited a greater portion of detail-related errors. The results suggest that not only phonological, but also general visual resolution deficits in LTM may play an important role in developmental dyslexia.

Characteristics and Impact of Drug Detailing for Gabapentin  

PubMed Central

Background Sales visits by pharmaceutical representatives (“drug detailing”) are common, but little is known about the content of these visits or about the impact of visit characteristics on prescribing behavior. In this study, we evaluated the content and impact of detail visits for gabapentin by analyzing market research forms completed by physicians after receiving a detail visit for this drug. Methods and Findings Market research forms that describe detail visits for gabapentin became available through litigation that alleged that gabapentin was promoted for “off-label” uses. Forms were available for 97 physicians reporting on 116 detail visits between 1995 and 1999. Three-quarters of recorded visits (91/116) occurred in 1996. Two-thirds of visits (72/107) were 5 minutes or less in duration, 65% (73/113) were rated of high informational value, and 39% (42/107) were accompanied by the delivery or promise of samples. During the period of this study, gabapentin was approved by the US Food and Drug Administration only for the adjunctive treatment of partial seizures, but in 38% of visits (44/115) the “main message” of the visit involved at least one off-label use. After receiving the detail visit, 46% (50/108) of physicians reported the intention to increase their prescribing or recommending of gabapentin in the future. In multivariable analysis, intent to increase future use or recommendation of gabapentin was associated with receiving the detail in a small group (versus one-on-one) setting and with low or absent baseline use of the drug, but not with other factors such as visit duration, discussion of “on-label” versus “off-label” content, and the perceived informational value of the presentation. Conclusions Detail visits for gabapentin were of high perceived informational value and often involved messages about unapproved uses. Despite their short duration, detail visits were frequently followed by physician intentions to increase their future recommending or prescribing of the drug.

So far events have been organised in Belgium, Finland, Portugal, Sweden, Switzerland and the United Kingdom. The purpose of these presentations is to raise the awareness of ESO amongst decision-makers, academia and the media. Over time, the scope and specific focus of the national events have varied, considering the particular circumstances and the wishes of the national hosts, and accordingly, the presentation in Denmark was primarily oriented towards industry. The meeting was initiated by the Royal Danish Consulate General in Munich in conjunction with the Confederation of Danish Industries and the Ministry for Science, Technology and Innovation. Leading up to the meeting, several articles about ESO had appeared in the Danish press and the 2nd TV Channel featured a report on the ESO projects also in connection with the event.

Major Element Control Presentation  

NSDL National Science Digital Library

The presentation is an introduction to the control of magma chemical compositions by the fractionation of crystallizing phases. It is followed by a lab exercise where students interpret volcanic rock petrology and a geochemical data set (from Iceland) in terms of sequences of fractionating phases. It is a useful as an introduction because it shows clearly, with data points, interpreted lines, and oral explanation how fractionating crystals can, in principal, control the chemical composition of derivative magmas. In context, this presentation is shown after phase diagram lectures and exercises, and it is linked to them by examining phase diagrams that illustrate the crystallization sequence (Olivine-plagioclase-augite). Further, a following lab exercise has the students deduce somewhat similar crystal fractionation controls for a set of Iceland lavas (for phenocryst petrology) and geochemical data sets (with which control lines are plotted). The presentation itself is not enough to make the connection between liquid composition changes, phase diagrams, and chemistry, but in the context of earlier phase diagrams, presentation, return to phase diagrams, and the petrology-geochemistry Iceland exercise, it helps get across the idea of how crystal fractionation can control magma evolution.

Graphical presentation of diagnostic information  

PubMed Central

Background Graphical displays of results allow researchers to summarise and communicate the key findings of their study. Diagnostic information should be presented in an easily interpretable way, which conveys both test characteristics (diagnostic accuracy) and the potential for use in clinical practice (predictive value). Methods We discuss the types of graphical display commonly encountered in primary diagnostic accuracy studies and systematic reviews of such studies, and systematically review the use of graphical displays in recent diagnostic primary studies and systematic reviews. Results We identified 57 primary studies and 49 systematic reviews. Fifty-six percent of primary studies and 53% of systematic reviews used graphical displays to present results. Dot-plot or box-and- whisker plots were the most commonly used graph in primary studies and were included in 22 (39%) studies. ROC plots were the most common type of plot included in systematic reviews and were included in 22 (45%) reviews. One primary study and five systematic reviews included a probability-modifying plot. Conclusion Graphical displays are currently underused in primary diagnostic accuracy studies and systematic reviews of such studies. Diagnostic accuracy studies need to include multiple types of graphic in order to provide both a detailed overview of the results (diagnostic accuracy) and to communicate information that can be used to inform clinical practice (predictive value). Work is required to improve graphical displays, to better communicate the utility of a test in clinical practice and the implications of test results for individual patients.

Leprosy: uncommon presentations.  

PubMed

The uniqueness of the clinical-dermatologic elements of leprosy recommends that control programs worldwide should diagnose the disease based on the so-called main clinical signs: cutaneous-neurological lesions with sensitivity-motor alterations without obligatory bacteriologic or histopathologic examination. The recognition of initial signs and symptoms of Hansen disease sometimes presents difficulties for its diagnosis, especially considering the relevance of an early diagnosis and the present guidelines for performance of decentralized treatment of the patient in the basic health-care network. The clinical cases illustrating this article were selected because of the degree of difficulty found in the confirmation of their diagnoses that required a histopathologic and/or bacteriologic examination.

How breast cancer presents.  

PubMed Central

A study of 501 new breast cancers in patients seen in a consulting surgical practice revealed that 87% were in patients 45 years of age or older. The patients had found 83% of the cancers. The distributions of size and stage were the same for the tumours found by the patients and those found by the referring physicians. Two thirds of the cancers had an associated visible clinical sign, demonstrating the importance of inspection in the examination of the breast. Dimpling, sometimes apparent only on manipulation of the tumour, was present with 264 of the cancers and was often associated with "minimal" lesions. Mammography was done for 63 of the breast cancers but it missed 27. Of the physician-found cancers 15 were in patients who had already had breast cancer, 4 were in patients presenting with symptomatic metastases and 14 were in women presenting with other disorders. Of the 52 cancers found by periodic examination 3 were locally advanced and 21 had axillary metastases, while among the 28 "early" cancers 12 were in women who were senile, mentally defective or psychotic. Only four of the cancers found by the physicians were in women under age 45; two were rapidly fatal, one had an axillary metastasis, and the fourth was in a woman who had had cancer of the opposite breast. The remaining 284 lesions found by periodic or routine examination in women under age 45 were benign. Thus, periodic or routine examination for unsuspected breast cancer in women under age 45 seems unjustified except in those who have already had breast cancer. Images FIG. 1 FIG. 2

Presenting Newtonian gravitation  

NASA Astrophysics Data System (ADS)

The basic principles of the Newtonian theory of gravitation are presented in a way which students may find more logically coherent, mathematically accessible and physically interesting than other approaches. After giving relatively simple derivations of the circular hodograph and the elliptical orbit from the inverse-square law, the concept of gravitational energy is developed from vector calculus. It is argued that the energy density of a gravitational field may reasonably be regarded as -g2/8?G, and that the inverse-square law may be replaced by a Schwarzschild-like force law without the need to invoke non-Euclidean geometry.

Group Oral Presentation  

NSDL National Science Digital Library

One topic I suggest to students is under the umbrella topic of Tectonics and Igneous Activity: Mt. Vesuvius. I expect the student group to research the area, explain WHY Mt. Vesuvius is there, what's gone on in the past, and evaluate whether or not they think the threat still exists. Once the physical world is addressed, I also enjoy when students discuss cultural aspects of the area. With this particular topic, we always hear about the 79AD eruption, and this adds a richness to each presentation.

Exit Presentation -- Maintaining Balance  

NASA Technical Reports Server (NTRS)

This slide presentation reviews the projects which the author engaged in during an internship at Johnson Space Center. Project 1 was involved with Stochastic Resonance (SR). Stochastic resonance is a phenomenon in which the response of a non-linear system to a weak input signal is optimized by the presence of a particular non-zero level of noise. The goal of this project was to develop a countermeasure for sensorimotor disturbances that are experienced after long duration space flight. The second project was a pilot study that was to examine how adaptation to a novel functional task was affected by postural disturbance.

Wind for Schools (Presentation)  

SciTech Connect

Schools are key to achieving the goal of producing 20% of the nation's electricity demand. Most significantly, schools are training the scientists, technicians, businesspeople, decisionmakers, and teachers of the future. What students learn and believe about wind energy will impact the United States' ability to create markets and policy, develop and improve technology, finance and implement projects, and create change in all of our public and private institutions. In the nearer term, school districts have large facility costs, electrical loads, and utility costs. They are always in search of ways to reduce costs or obtain revenue to improve educational programs. Schools value teaching about the science and technology of renewable energy. They are important opinion leaders, particularly in rural communities. And their financial structures are quite different from other institutions (funding, incentives, restrictions, etc.). Learning objectives: The presentation will use case studies, project experience, and discussion with the audience to convey the current status of wind energy applications and education in U.S. schools and understanding of the elements that create a successful school wind energy project. The presentation will provide attendees with a background in the current level of knowledge and generate discussion on several themes.

Rhinosporidiosis: An unusual presentation.  

PubMed

Rhinosporidiosis is a chronic granulomatous disease that primarily affects the mucous membranes of the nose and nasopharynx. It is caused by Rhinosporidium seeberi. Clinically it presents as a reddish, bleeding, polypoid mass with a characteristic strawberry-like appearance on its surface, which is caused by the presence of mature sporangia. In the case described here, a 35-year-old man presented with a 6-month history of a slowly growing polypoid mass in his left nasal cavity. The surface of the mass was smooth, pale, and covered with nasal mucosa. It was attached to the nasal septum. Fine-needle aspiration cytology was suggestive of a parasitic cyst. The mass was excised with the use of local anesthesia. Histopathologic examination of the resected specimen revealed rhinosporidiosis. Prior to this diagnosis, the patient had not exhibited most of the typical clinical features that are suggestive of rhinosporidiosis. In the case of a nasal mass, a diagnosis of rhinosporidiosis is important to establish prior to any surgery because bleeding during and after surgery is usually profuse and can be life-threatening. The site of the excised mass should be cauterized to prevent recurrence. PMID:25025417

Giving effective presentations.  

PubMed

Apprehension about oral communication, or public speaking is rated as the number one fear among most individuals. Developing skill in, and comfort with, public speaking is important whether we are presenting oral reports and proposals, responding to questions, or training co-workers. Effective speakers are able to communicate information in a way that stimulates interest, helps the audience to understand and remember, and influences attitudes and behaviours. Many of us think that effective speakers are born rather than made. In truth most successful speakers work hard and invest a great deal of time and effort in to improving their speaking capabilities. Effective public speaking is a learned skill and activity that requires lots of practice. Like other learned skills, having a strategy with clear action steps can help you achieve your goal.

Water Past and Present  

NASA Technical Reports Server (NTRS)

This image of sulfate and water ice deposits in the Olympia Undae region of Mars was taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) at 2213 UTC on October 2, 2006 (6:13 p.m. EDT) near 81.6 degrees north latitude, 188.9 degrees east longitude. CRISM's image was taken in 544 colors covering 0.36-3.92 micrometers, and shows features as small as 20 meters (66 feet) across.

Olympia Undae is a large dune field that stretches some 1,100 kilometers (684 miles) across the northern polar region of Mars, just south of the ice cap. The region holds a vast expanse of complex, shifting dunes and is best described as a sand sea or erg similar to the Sahara.

The two images above provide interesting clues into Mars' history by revealing the planet's wet past and frozen present. The left image is an infrared, false-color image that reveals dark-colored dunes overlying a lighter substrate. Spectral data from CRISM and its sister instrument OMEGA suggest similar compositions of these dunes and the dark basal, or lowermost, unit of the north polar layered deposits. HIRISE images revealed cross-bedding (crossed layers that are oriented at a different angle to the main layer) in this dark unit. On Earth, cross-bedded sediments can form in both windy and watery environments. The dark polar basal unit on Mars is interpreted as a sand sheet underlying and pre-dating the ice, and now being eroded to dunes by the Martian winds.

The mineralogy of the Olympia Undae region holds a record of past water. CRISM spectral data (right image) shows that the darker dunes are rich in polyhydrated sulfate (sulfates with more than one water molecule incorporated into each molecule of the mineral). The mineral gypsum is a polyhydrated sulfate, and the most likely constituent in these dunes. The gypsum probably formed by evaporation of ancient, saline water or by aqueous alteration of the silicate portion of the dune material. Areas shaded in red are cover by dust.

Blue areas in both images indicate water ice, outliers of the polar cap that persist well into or even through the Martian summer. CRISM has observed these water ice outliers in shadows on north-facing slopes that are located at relatively low latitudes. In the images above, water ice is found on the northern slopes of both the inner and outer portions of a crater rim. CRISM also found that these icy outliers are concentrated in bright areas that reflect more of the sun's warming rays and thus stay cold, and that they are less common in darker regions that absorb the sun's ray and become warmer.

The combination of hydrated sulfates and water ice provides an interesting view into Mars' geologic history. In one image we see a record of past water trapped in sulfates and present water persisting as surface ice. As CRISM continues to gather data about the mineralogy and atmosphere of Mars, a clearer picture of the planet's wet past and frozen present emerges.

CRISM is one of six science instruments on NASA's Mars Reconnaissance Orbiter. Led by The Johns Hopkins University Applied Physics Laboratory, Laurel, Md., the CRISM team includes expertise from universities, government agencies and small businesses in the United States and abroad. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter and the Mars Science Laboratory for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the orbiter.

MSG RAO Presentation  

NASA Astrophysics Data System (ADS)

BACKGROUND The Meteosat Second Generation (MSG) Research Announcement of Opportunity (RAO) was released by ESA and EUMETSAT in 1999, after a first warning issued in September 1998. The RAO main objective is to promote the scientific use of the new MSG satellites outside the operational meteorological user community, also in synergy with ERS and Envisat data. The variety and quality of the selected proposals proved the usefulness of such joint initiative. 2. STATUS OF THE RAO A total of 43 proposals were selected in 1999. Following the delay in the MSG-1 launch (which operational name is Meteosat-8), the PIs were contacted in early 2003 in order to confirm the interest to continue with the project. There were 5 withdrawals due to various reasons. The PIs have been receiving news through a dedicated WEB site or by emails. Each PI has been assigned a correspondent from ESA or EUMETSAT to follow up the project through the site: http://eopi.esa.int/esa/esa where the papers presented at this Workshop will be included as the first report. 3. THE MSG RAO WORKSHOPS In the framework of the MSG RAO, a series of workshops are organised which goal is to establish a structured dialogue and interactions among the MSG Principal Investigators (PIs) and ESA/EUMETSAT, respectively. Each of these workshops is focusing on a specific aspect, in addition to the necessary exchange of information. 4. OBJECTIVES OF THE BOLOGNA WORKSHOP The focus of the first workshop (17-19 May 2000) was on the presentation of MSG features and of all selected RAO projects. It was a starting point for continued interaction within the MSG RAO community (selected PIs and their co-Investigators, Co-Is). The first MSG RAO workshop provided a forum for discussion among scientists, and ESA and EUMETSAT, leading to a continuous scientific co-operation. Requirements and possibilities with regard to data delivery were formulated and discussed at this workshop. In particular, PIs were asked to specify the minimal and nominal data requirements for the first year after the end of the MSG commissioning. PI's recommendations formulated at this first workshop resulted in an increase of delivery capability of SEVIRI data from the archive and the development of a simple IDL interface to handle SEVIRI data.

Bilirubin present in diverse angiosperms  

PubMed Central

Background and aims Bilirubin is an orange-yellow tetrapyrrole produced from the breakdown of heme by mammals and some other vertebrates. Plants, algae and cyanobacteria synthesize molecules similar to bilirubin, including the protein-bound bilins and phytochromobilin which harvest or sense light. Recently, we discovered bilirubin in the arils of Strelitzia nicolai, the White Bird of Paradise Tree, which was the first example of this molecule in a higher plant. Subsequently, we identified bilirubin in both the arils and the flowers of Strelitzia reginae, the Bird of Paradise Flower. In the arils of both species, bilirubin is present as the primary pigment, and thus functions to produce colour. Previously, no tetrapyrroles were known to generate display colour in plants. We were therefore interested in determining whether bilirubin is broadly distributed in the plant kingdom and whether it contributes to colour in other species. Methodology In this paper, we use HPLC/UV and HPLC/UV/electrospray ionization-tandem mass spectrometry (HPLC/UV/ESI-MS/MS) to search for bilirubin in 10 species across diverse angiosperm lineages. Principal results Bilirubin was present in eight species from the orders Zingiberales, Arecales and Myrtales, but only contributed to colour in species within the Strelitziaceae. Conclusions The wide distribution of bilirubin in angiosperms indicates the need to re-assess some metabolic details of an important and universal biosynthetic pathway in plants, and further explore its evolutionary history and function. Although colour production was limited to the Strelitziaceae in this study, further sampling may indicate otherwise.

Spectrophotometry: Past and Present  

NASA Astrophysics Data System (ADS)

I describe the rise of optical region spectrophotometry in the 1960's and 1970's when it achieved a status as a major tool in stellar research through its decline and near demise at present. With absolutely calibrated fluxes and Balmer profiles usually of H-gamma, astronomers used model atmospheres predictions to find both the effective temperatures and surface gravities of many stars. Spectrophotometry as I knew it was photometrically calibrated low dispersion spectroscopy with a typical resolution of order 25 A. A typical data set consists of 10 to 15 values covering most of the optical spectral region. The strengths and shortcomings of the rotating grating scanners are discussed. The accomplishments achieved using spectrophotometric data, which were obtained with instruments using photomultipliers, are reviewed. Extensions to other spectral regions are noted and attempts to use observations from space to calibrate the optical region will be discussed. There are two steps to fully calibrate flux data. The first requires the calibration of the fluxes of one or more standard stars against sources calibrated absolutely in a laboratory. The use of Vega as the primary standard has been both a blessing as it is so bright and a curse especially as modeling it correctly requires treating it as a fast rotating star seen nearly pole-on. At best its calibration has errors of about 1%. The other step is to apply extinction corrections for the Earth's atmosphere and then calibrate the fluxes using the fluxes of standard stars. Now the ASTRA Spectrophotometer promises a revitalization of the use and availability of optical flux data. Its design specifications included solutions to the problems of past optical spectrophotometric instruments.

Indian aerosols: present status.  

PubMed

This article presents the status of aerosols in India based on the research activities undertaken during last few decades in this region. Programs, like International Geophysical Year (IGY), Monsoon Experiment (MONEX), Indian Middle Atmospheric Program (IMAP) and recently conducted Indian Ocean Experiment (INDOEX), have thrown new lights on the role of aerosols in global change. INDOEX has proved that the effects of aerosols are no longer confined to the local levels but extend at regional as well as global scales due to occurrence of long range transportation of aerosols from source regions along with wind trajectories. The loading of aerosols in the atmosphere is on rising due to energy intensive activities for developmental processes and other anthropogenic activities. One of the significant observation of INDOEX is the presence of high concentrations of carbonaceous aerosols in the near persistent winter time haze layer over tropical Indian Ocean which have probably been emitted from the burning of fossil-fuels and biofuels in the source region. These have significant bearing on the radiative forcing in the region and, therefore, have potential to alter monsoon and hydrological cycles. In general, the SPM concentrations have been found to be on higher sides in ambient atmosphere in many Indian cities but the NOx concentrations have been found to be on lower side. Even in the haze layer over Indian Ocean and surrounding areas, the NOx concentrations have been reported to be low which is not conducive of O3 formation in the haze/smog layer. The acid rain problem does not seem to exist at the moment in India because of the presence of neutralizing soil dust in the atmosphere. But the high particulate concentrations in most of the cities' atmosphere in India are of concern as it can cause deteriorated health conditions. PMID:12492171

FEL optics - present and future  

SciTech Connect

As free-electron lasers advance to both higher average powers and shorter wavelengths, the requirements on the optical system become more and more stringent. In this paper, the physical reasoning behind these requirements and how they are met in both current and proposed oscillators are examined. The cavity being used in a current FEL experiment will be considered in some detail. Future glancing incidence ring cavities are also discussed with an emphasis on concept rather than engineering detail. 9 references.

Eros details enhanced by computer processing  

NASA Technical Reports Server (NTRS)

The NEAR camera's ability to show details of Eros's surface is limited by the spacecraft's distance from the asteroid. That is, the closer the spacecraft is to the surface, the more that details are visible. However mission scientists regularly use computer processing to squeeze an extra measure of information from returned data. In a technique known as 'superresolution', many images of the same scene acquired at very, very slightly different camera pointing are carefully overlain and processed to bright out details even smaller than would normally be visible. In this rendition constructed out of 20 image frames acquired Feb. 12, 2000, the images have first been enhanced ('high-pass filtered') to accentuate small-scale details. Superresolution was then used to bring out features below the normal ability of the camera to resolve.

Built and managed by The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, NEAR was the first spacecraft launched in NASA's Discovery Program of low-cost, small-scale planetary missions. See the NEAR web page at http://near.jhuapl.edu for more details.

Third Sound Amplification and Detailed Balance  

NASA Astrophysics Data System (ADS)

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.

Contrast-detail phantom scoring methodology.  

PubMed

Published results of medical imaging studies which make use of contrast detail mammography (CDMAM) phantom images for analysis are difficult to compare since data are often not analyzed in the same way. In order to address this situation, the concept of ideal contrast detail curves is suggested. The ideal contrast detail curves are constructed based on the requirement of having the same product of the diameter and contrast (disk thickness) of the minimal correctly determined object for every row of the CDMAM phantom image. A correlation and comparison of five different quality parameters of the CDMAM phantom image determined for obtained ideal contrast detail curves is performed. The image quality parameters compared include: (1) contrast detail curve--a graph correlation between "minimal correct reading" diameter and disk thickness; (2) correct observation ratio--the ratio of the number of correctly identified objects to the actual total number of objects multiplied by 100; (3) image quality figure--the sum of the product of the diameter of the smallest scored object and its relative contrast; (4) figure-of-merit--the zero disk diameter value obtained from extrapolation of the contrast detail curve to the origin (e.g., zero disk diameter); and (5) k-factor--the product of the thickness and the diameter of the smallest correctly identified disks. The analysis carried out showed the existence of a nonlinear relationship between the above parameters, which means that use of different parameters of CDMAM image quality potentially can cause different conclusions about changes in image quality. Construction of the ideal contrast detail curves for CDMAM phantom is an attempt to determine the quantitative limits of the CDMAM phantom as employed for image quality evaluation. These limits are determined by the relationship between certain parameters of a digital mammography system and the set of the gold disks sizes in the CDMAM phantom. Recommendations are made on selections of CDMAM phantom regions which should be used for scoring at different image quality and which scoring methodology may be most appropriate. Special attention is also paid to the use of the CDMAM phantom for image quality assessment of digital mammography systems particularly in the vicinity of the Nyquist frequency. PMID:15839353

Past and present Aral Sea  

NASA Astrophysics Data System (ADS)

The tragedy of disappearing of Aral Sea is well known to the World. Before and after collapse of Soviet Union, a huge quantity of scientific and popular editions described with grief the situation around the Aral Sea. After the NIS states became independent, World Bank, UNDP, UNEP in proper competition with each other had provided some assessment of the situation through presentation of some small and medium grants, but after 2000, the local population remained alone with own problems. Although on the eyes of the present generation a unique transformation of great water body into deserts took place, the global scientific community did not find forces and financing for real and detail investigation of the processes accompanying the Sea shrinking and land formation. We should acknowledge and give big respect to NATO, later to German Government that through GTZ (now GIZ) - German International Collaboration Agency - and GFZ (Potzdam) paid attention to this area of environment crisis and organized scientific and protective design in the so-called Priaralie - the territory around the drying Sea and delta of the two rivers - Amudarya and Syrdarya. Thank to this assistance, the local specialists in collaboration with limited a number of foreign scientists (N.Aladin, P.Zavialov, Joop de Schutter, Hans Wilps, Hedi Oberhansli) organized significant works for detail socioeconomic, ecological and hydrological assessment situation in Priaralie and on the Aral sea coast. On this base, Ministry of Agriculture and Water resources of Uzbekistan and State Committee of Water resources of Kazakhstan developed a plan of rehabilitation of Amudarya and Syrdarya deltas and started implementation of these projects. If Kazakh water authority moved ahead in wetland restoration faster, a forestation of delta and drying bed of Aral Sea got big success in Uzbek territory. 244 thousands hectares of saxsaul and tamarix were planted for protection of the Priaralie. By request of GTZ SIC, ICWC organized in 2005-2009 sixth expeditions for complex remote sensing and ground investigations Aral Sea former bottom that were complemented in 2010 -2011 by two expeditions with GFZ. As a result, the landscape, soils and environment mapping was done with determination of ecologically unstable zones and assessment total change of lands situation compared with the pre-independence time. Moreover - methodic of monitoring water, environment and hydro geological indicators on the all deltas area was elaborated, organized its testing and combined with remote sensing data on Amudarya delta for 2009-2012. It permits to SIC ICWC to organize systematic permanent (decadal) monitoring and recording of size, volume and level of water in Aral Sea. Since the beginning of regular observations over the Aral Sea level, 2 periods can be emphasized: 1. Conditionally natural period - 1911-1960 - characterized by a relatively stable hydrological regime, with fluctuations in the level around 53 m and the range of inter-annual fluctuations at no more than 1 m., when the sea received annually about a half of the run-off in the Syrdarya and Amudarya Rivers, i.e. 50-60 km3/yr. 2. Intensive anthropogenic impact period - since the 1960s, a vast extension of irrigable land was carried out in Central Asia that resulted in intensive diversion of river run-off. Since then, the sea level has been falling steadily, causing a dramatic reduction in the water surface area, a decrease in water volume and depths, great changes in shoreline configuration and an expansion of the desert areas adjacent to the Aral Sea. From 1960-1985, when the sea was an integral water body, slight lowering in the sea level took place until the 1970s, when the sea-level decreased with the mean level lowering 1 m. The desiccation process accelerated visibly from the mid 1970s. In 1975-1980, the level decreased by 0.65 m a year on average. Moreover, the level dropped greatly, when the run-off of the Amudarya did not reach the Aral Sea any more (1980-1990). Kokaral was the first of the large islands becoming a peninsula, separa

Structural concepts and details for seismic design  

SciTech Connect

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.

Detailed design of a 100-We multicell thermionic power supply.  

NASA Technical Reports Server (NTRS)

Confirmation of the general trends of a previously reported parametric study of plutonia-fueled thermionic generators in a detailed 100-We generator design. The detailed design takes into account the additional weight of system-integration components and shows that design refinements of all aeroshell components are possible when a specific generator configuration is considered. An optimized 100-We thermionic power supply design is presented, reflecting a 0.98 reliability goal after five years of operation. The optimum multicell array consists of 28 isomite converters, each producing approximately 3.6 We at end-of-life. The optimum arrangement of converters in the aeroshell is a four-column, seven-row stacking configuration connected electrically as a two-column, 14-row array.

Ho?ava-Lifshitz gravity: Detailed balance revisited  

NASA Astrophysics Data System (ADS)

We attempt a critical reconsideration of “detailed balance” as a principle that can be used to restrict the proliferation of couplings in Ho?ava-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.

Numerical optimization of conical flow waveriders including detailed viscous effects  

NASA Technical Reports Server (NTRS)

A family of optimized hypersonic waveriders is generated and studied wherein detailed viscous effects are included within the optimization process itself. This is in contrast to previous optimized waverider work, wherein purely inviscid flow is used to obtain the waverider shapes. For the present waveriders, the undersurface is a streamsurface of an inviscid conical flowfield, the upper surface is a streamsurface of the inviscid flow over a tapered cylinder (calculated by the axisymmetric method of characteristics), and the viscous effects are treated by integral solutions of the boundary layer equations. Transition from laminar to turbulent flow is included within the viscous calculations. The optimization is carried out using a nonlinear simplex method. The resulting family of viscous hypersonic waveriders yields predicted high values of lift/drag, high enough to break the L/D barrier based on experience with other hypersonic configurations. Moreover, the numerical optimization process for the viscous waveriders results in distinctly different shapes compared to previous work with inviscid-designed waveriders. Also, the fine details of the viscous solution, such as how the shear stress is distributed over the surface, and the location of transition, are crucial to the details of the resulting waverider geometry. Finally, the moment coefficient variations and heat transfer distributions associated with the viscous optimized waveriders are studied.

Detailed chemical kinetic oxidation mechanism for a biodiesel surrogate  

SciTech Connect

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. Computed results have been compared with methyl decanoate experiments in an engine and oxidation of rapeseed oil methyl esters in a jet stirred reactor. An important feature of this mechanism is its ability to reproduce the early formation of carbon dioxide that is unique to biofuels and due to the presence of the ester group in the reactant. The model also predicts ignition delay times and OH profiles very close to observed values in shock tube experiments fueled by n-decane. These model capabilities indicate that large n-alkanes can be good surrogates for large methyl esters and biodiesel fuels to predict overall reactivity, but some kinetic details, including early CO2 production from biodiesel fuels, can be predicted only by a detailed kinetic mechanism for a true methyl ester fuel. The present methyl decanoate mechanism provides a realistic kinetic tool for simulation of biodiesel fuels.

Optimum detailed design of reinforced concrete frames using genetic algorithms  

NASA Astrophysics Data System (ADS)

This article presents the application of the genetic algorithm to the optimum detailed design of reinforced concrete frames based on Indian Standard specifications. The objective function is the total cost of the frame which includes the cost of concrete, formwork and reinforcing steel for individual members of the frame. In order for the optimum design to be directly constructible without any further modifications, aspects such as available standard reinforcement bar diameters, spacing requirements of reinforcing bars, modular sizes of members, architectural requirements on member sizes and other practical requirements in addition to relevant codal provisions are incorporated into the optimum design model. The produced optimum design satisfies the strength, serviceability, ductility, durability and other constraints related to good design and detailing practice. The detailing of reinforcements in the beam members is carried out as a sub-level optimization problem. This strategy helps to reduce the size of the optimization problem and saves computational time. The proposed method is demonstrated through several example problems and the optimum results obtained are compared with those in the available literature. It is concluded that the proposed optimum design model can be adopted in design offices as it yields rational, reliable, economical, time-saving and practical designs.

A Detailed Chemical Kinetic Model for TNT  

SciTech Connect

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.

Why a detailed examination after acute pancreatitis?  

PubMed

During the 1965-9 period, we studied the consequences of acute pancreatitis in a group of 53 patients (1). Using the 1963 Marseille classification of pancreatitis (2), we pointed, inter alia, to the incidence of changes in exocrine and endocrine functions of the pancreas in some patients (something that we would refer to as residua after acute pancreatitis, today), and emphasized the need for a detailed examination of patients, following an attack of acute pancreatitis. In this article we wish to reemphasize the need for such detailed examination, this time in connection with new classifications of pancreatitis, i.e., the Revised Classification of Pancreatitis--Marseille, 1984 (3), and the Pancreatitis Classification of Marseille-Rome 1988 (4,5). The latter classification, based on studies of lesions and causes of pancreatitis, constitutes yet another attempt to integrate pathology into the prerequisites for clear-cut definition of the disease. However, a definition of pancreatitis, based on pathological findings, remains an aim yet to be attained in everyday clinical practice. That is why the clinician will rely on the Marseille classification (1984), taking into account the Marseille-Rome classification (1988). PMID:1946317

HUBBLE CAPTURES DETAILED IMAGE OF URANUS' ATMOSPHERE

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.

Detailed observations of the source of terrestrial narrowband electromagnetic radiation  

NASA Technical Reports Server (NTRS)

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.

Second-generation heliostat development. Volume 1. Detailed design report  

SciTech Connect

The results of a second-generation heliostat development program completed to date are presented. This includes a presentation of the detailed design of the second-generation heliostat with the supportive analyses and component test data; preliminary design of the manufacturing plant; and the projected cost to manufacture, transport, install, and maintain 50,000 heliostats per year installed in 50-MWe fields. The heliostat design presented is the mass production design on which the cost estimates were based. The prototype heliostats to be tested will be as close to the mass production design as practical. Due to the absence of mass production tooling, the prototype heliostats have some differences from the mass production heliostats. These differences are described at the component level where applicable.

Scurvy Is Still Present in Developed Countries  

PubMed Central

Introduction Scurvy, while uncommon, still occurs in developed countries despite the widespread availability of vitamins and fortified foods. A vitamin C deficiency prevalence of 10 to 14% in adults was reported in the National Health and Nutrition Examination Survey (NHANES) in 1994. Objective We report the case of a 57-year-old male who presented with a combined vitamin C deficiency (scurvy) and a Zinc deficiency. Interventions He came to the emergency department complaining of a painful swollen ecchymotic leg and dyspnea. Prescriptions for narcotics did not relieve his symptoms. When a detailed dietary history was obtained, we added scurvy to the differential diagnosis. An extensive evaluation excluded trauma, coagulopathies, neoplasia, and vasculitides. Main Result The combination of a classic skin biopsy and a low vitamin C level confirmed the diagnosis. Conclusion This presentation illustrates the necessity of including scurvy in the differential diagnosis of ecchymoses and demonstrates specific populations at risk: single adults and the elderly with deficient diets.

NASA Astrophysics Data System (ADS)

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.

Detailed fluctuation theorem for mesoscopic modeling  

NASA Astrophysics Data System (ADS)

The detailed fluctuation theorem is derived. The basic assumptions are phase space incompressibility (Liouville’s theorem) and time reversibility on the microscopic level. The theorem relates the conditional probability to end up in a mesoscopic state ?B at time tB , starting from ?A at time tA , to the time-reversed process. The ratio of these two probability densities is related to the entropy difference of the two mesoscopic states. The fluctuation theorem remains valid even far from equilibrium as long as the local equilibrium condition is obeyed. It is shown that the theorem imposes constraints on the form mesoscopic equations can take. For stochastic differential equations a generalized kinetic form is derived. The fluctuation theorem can be used to derive thermodynamically consistent simulation techniques. At the end of this paper the relation with the GENERIC formalism is discussed.

Detailed structure within a tropical cyclone ``eye''  

NASA Astrophysics Data System (ADS)

The characteristics of the ``eye'' and eyewall of a Tropical Cyclone (TC) are examined with a wind profiler and upper-soundings around a small island belonging to Japan. There are few observations of wind behavior in the eye of a TC with high time and height resolutions. In the eye of the TC, weak cyclonic wind and updraft formed like a cylinder centered on the TC. The updraft did not form clouds and precipitation because stable and relatively dry air existed in the middle troposphere. There were dry layers above the middle troposphere in the eye, especially in the lower layers on the front side of the TC. Therefore, the rainfall associated with the eyewall was strengthened and developed. This is the first time that the detailed wind behavior in the eye of the TC in the developing and mature stage has been observed.

Hubble Captures Detailed Image of Uranus' Atmosphere  

NASA Technical Reports Server (NTRS)

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.

Detailed and reduced chemical-kinetic descriptions for hydrocarbon combustion  

NASA Astrophysics Data System (ADS)

Numerical and theoretical studies of autoignition processes of fuels such as propane are in need of realistic simplified chemical-kinetic descriptions that retain the essential features of the detailed descriptions. These descriptions should be computationally feasible and cost-effective. Such descriptions are useful for investigating ignition processes that occur, for example, in homogeneous-charge compression-ignition engines, for studying the structures and dynamics of detonations and in fields such as multi-dimensional Computational Fluid Dynamics (CFD). Reduced chemistry has previously been developed successfully for a number of other hydrocarbon fuels, however, propane has not been considered in this manner. This work focuses on the fuels of propane, as well propene, allene and propyne, for several reasons. The ignition properties of propane resemble those of other higher hydrocarbons but are different from those of the lower hydrocarbons (e.g. ethylene and acetylene). Propane, therefore, may be the smallest hydrocarbon that is representative of higher hydrocarbons in ignition and detonation processes. Since the overall activation energy and ignition times for propane are similar to those of other higher hydrocarbons, including liquid fuels that are suitable for many applications, propane has been used as a model fuel for several numerical and experimental studies. The reason for studying elementary chemistry of propene and C3H4 (allene or propyne) is that during the combustion process, propane breaks down to propene and C3H4 before proceeding to products. Similarly, propene combustion includes C3H4 chemistry. In studying propane combustion, it is therefore necessary to understand the underlying combustion chemistry of propene as well as C3H 4. The first part of this thesis focuses on obtaining and testing a detailed chemical-kinetic description for autoignition of propane, propene and C 3H4, by comparing predictions obtained with this detailed mechanism against numerous experimental data available from shock-tube studies and flame-speed measurements. To keep the detailed mechanism small, attention is restricted to pressures below about 100 atm, temperatures above about 1000 K and equivalence ratios less than about 3. Based on this detailed chemistry description, short (or skeletal) mechanisms are then obtained for each of the three fuels by eliminating reactions that are unimportant for the autoignition process under conditions presented above. This was achieved by utilizing tools such as sensitivity and reaction pathway analyses. Two distinct methodologies were then used in order to obtain a reduced mechanism for autoignition from the short mechanisms. A Systematic Reduction approach is first taken that involves introducing steady-state approximations to as many species as analytically possible. To avoid resorting to numerical methods, the analysis for obtaining ignition times for heptane, presented by Peters and co-workers is followed in order to obtain a rough estimate for an expression of propane ignition time. The results from this expression are then compared to the ignition times obtained computationally with the detailed mechanism. The second method is an Empirical Approach in which chemistry is not derived formally, but rather postulated empirically on the basis of experimental, computational and theoretical observations. As a result, generalized reduced mechanisms are proposed for autoignition of propane, propene and C3H 4. Expressions for ignition times obtained via this empirical approach are compared to the computational results obtained from the detailed mechanism.

Simulating What You See Presentation  

NSDL National Science Digital Library

This invited talk shows how the Tracker video analysis and modeling program enables students to create particle model simulations based on Newton's laws and to compare their behavior directly with that of real-world objects captured on video. Tracker's "model builder" provides a gentle introduction to dynamic modeling by making it easy to define and modify force expressions, parameter values and initial conditions while hiding the numerical algorithm details. Because the model simulations synchronize with and draw themselves right on the video, students can test their models experimentally by direct visual inspection, a process that is both intuitive and discerning. A digital library browser enables users to open videos and models directly from web-based collections such as the ComPADRE National Science Digital Library.

A detailed spectroscopic study of an Italian fresco  

NASA Astrophysics Data System (ADS)

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.

Detailed aeromagnetic investigation of the Arctic Basin. II  

NASA Technical Reports Server (NTRS)

Remote sensing techniques must be employed to determine the nature of the regional geologic and tectonic structure of the Arctic Basin. Magnetic measurements from aircraft are the most commonly used method. Since 1972 the U.S. Navy has been engaged in a long-term program of mapping, in relative detail, the earth's magnetic field over that portion of the Arctic Basin accessible to the P3 aircraft. A description is presented of the results of the 1977 and 1978 field efforts. The description represents a continuation of an investigation reported by Vogt et al. (1979). The efforts currently considered were directed towards understanding the nature, age, and origin of the major physiolographic features of the western Arctic Basin. Particular attention was given to the Canada and Makarov basins (Fletcher Abyssal Plain) and the Alpha Ridge. The aeromagnetic data are interpreted with respect to the theory of origin presented by Carey (1958).

Revisiting the Concept of Level of Detail in 3d City Modelling  

NASA Astrophysics Data System (ADS)

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.

Detailed surveys of offshore Peru margin  

SciTech Connect

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.

Murky details of the Miocene Atlantic Ocean  

NASA Astrophysics Data System (ADS)

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.

Parabiosis in mice: a detailed protocol.  

PubMed

Parabiosis is a surgical union of two organisms allowing sharing of the blood circulation. Attaching the skin of two animals promotes formation of microvasculature at the site of inflammation. Parabiotic partners share their circulating antigens and thus are free of adverse immune reaction. First described by Paul Bert in 1864(1), the parabiosis surgery was refined by Bunster and Meyer in 1933 to improve animal survival(2). In the current protocol, two mice are surgically joined following a modification of the Bunster and Meyer technique. Animals are connected through the elbow and knee joints followed by attachment of the skin allowing firm support that prevents strain on the sutured skin. Herein, we describe in detail the parabiotic joining of a ubiquitous GFP expressing mouse to a wild type (WT) mouse. Two weeks after the procedure, the pair is separated and GFP positive cells can be detected by flow cytometric analysis in the blood circulation of the WT mouse. The blood chimerism allows one to examine the contribution of the circulating cells from one animal in the other. PMID:24145664

Tuberculous involvement of the pleura usually presents as pleural effusion, empyema or pleural thickening. Pleural tuberculosis presenting with multiple masses without parenchymal involvement or lymphadenopathy has been reported rarely in the English literature. We report a case of a 68-year-old male with unilateral pleural tuberculosis presenting as multiple different sized nodular masses evident on computed tomography (CT) of the chest with a large hemorrhagic pleural effusion, which initially raised a possibility of mesothelioma. Pleuroscopy also revealed multiple pleural masses. Pathological examination of the biopsy specimen showed multiple epitheloid cell granulomas confirming the diagnosis.

No Presentism in Quantum Gravity  

NASA Astrophysics Data System (ADS)

This essay offers a reaction to the recent resurgence of presentism in the philosophy of time. What is of particular interest in this renaissance is that a number of recent arguments supporting presentism are crafted in an untypically naturalistic vein, breathing new life into a metaphysics of time with a bad track record of co-habitation with modern physics. Against this trend, the present essay argues that the pressure on presentism exerted by special relativity and its core lesson of Lorentz symmetry cannot easily be shirked. A categorization of presentist responses to this pressure is offered. As a case in point, I analyze a recent argument by Monton (Presentism and quantum gravity, 263-280, 2006) presenting a case for the compatibility of presentism with quantum gravity. Monton claims that this compatibility arises because there are quantum theories of gravity that use fixed foliations of spacetime and that such fixed foliations provide a natural home for a metaphysically robust notion of the present. A careful analysis leaves Monton's argument wanting. In sum, the prospects of presentism to be alleviated from the stress applied by fundamental physics are faint.

Explanation, Special Relativity, and Presentism  

NASA Astrophysics Data System (ADS)

Which aspects of our experience of time can special relativity be used to explain? In this paper I focus on those aspects of our experience of time associated with presentism. Special relativity has been used to argue against presentism, and to insist that those aspects of our experience of time that are central to the presentist thesis are to be "explained away" as somehow illusory. In this paper I offer a version of special relativistic presentism that has the potential to explain (rather than explain away) these aspects of our experience of time, including the short duration of the present and temporal becoming.

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.

A Detailed Modeling Study of Propane Oxidation  

SciTech Connect

A detailed chemical kinetic mechanism has been used to simulate ignition delay times recorded by a number of experimental shock tube studies over the temperature range 900 {le} T {le} 1800 K, in the pressure range 0.75-40 atm and in the equivalence ratio range 0.5 {le} {phi} {le} 2.0. Flame speed measurements at 1 atm in the equivalence ratio range 0.4 {le} {phi} {le} 1.8 have also been simulated. Both of these data sets, particularly those recorded at high pressure, are of particular importance in validating a kinetic mechanism, as internal combustion engines operate at elevated pressures and temperatures and rates of fuel oxidation are critical to efficient system operation. Experiments in which reactant, intermediate and product species were quantitatively recorded, versus temperature in a jet-stirred reactor (JSR) and versus time in a flow reactor are also simulated. This data provide a stringent test of the kinetic mechanism as it must reproduce accurate quantitative profiles for all reactant, intermediate and product species. The JSR experiments were performed in the temperature range 1000-1110 K, in the equivalence ratio range 0.5 {le} {phi} {le} 4.0, at a pressure of 5 atm. These experiments are complemented by those carried out in a flow reactor in the temperature range 660-820 K, at 10 atm and at an equivalence ratio of 0.4. In addition, burner stabilized flames were simulated, where chemical species profiles were measured at atmospheric pressure for two propane-air flat flames. Overall, reasonably good agreement is observed between the model simulations and the experimental results.

Detailed modeling of Martian ice clouds as observed by SPICAM  

NASA Astrophysics Data System (ADS)

MARSBOX is a newly developed model with detailed size-resolved microphysics for Martian dust and ice clouds, which is based on a state-of-the-art model for cirrus and PSCs on the Earth [Larsen, 2000; Daerden et al, 2007]. This box model has been applied in a 1D stacked mode, allowing for sedimentation and vertical eddy mixing. The 1D model is driven by the meteorology and water vapor of the Global Mars Multiscale Model, or GM3 [Moudden and McConnell, 2005], a recent Mars 3D GCM. We present simulations for selected case studies in the Tropical Cloud Belt region and compare to ice cloud optical thickness retrieved from SPICAM UV nadir observations [Mateshvili et al, 2007]. The differences in ice formation between the detailed microphysical MARSBOX model and the simple bulk ice scheme of GM3 are assessed. The neglect of the process of nucleation and activation of available condensation nuclei in the simple scheme leads to an overestimation of the water content in the clouds. This may have consequences for the modeling of the global water cycle on Mars. We illustrate that MARSBOX is able to reproduce the SPICAM measurements, although the microphysical calculations are highly sensitive to small variations in the GCM fields.

A data-management system for detailed areal interpretive data  

USGS Publications Warehouse

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.

Urticarial vasculitis: a unique presentation.  

PubMed

Urticarial vasculitis is a relatively rare diagnosis in a patient presenting with urticaria. The process is classically described as a generalized eruption, painful more so than pruritic, lasting longer than 24 hours. Two forms of urticarial vasculitis have been described: ahypocomplementemic form more commonly associated with systemic disease, and a normocomplementemic form that is generally limited to the skin. We report on a uniquely distributed vasculitic eruption restricted mainly to the anterior belt line area in a patient presenting with urticaria and intense pruritus. Urticarial vasculitis as a unique entity is reviewed along with its clinical and histopathologic presentation and the pharmacologic agents used for treatment. PMID:19373142

A centralized audio presentation manager  

SciTech Connect

The centralized audio presentation manager addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Time dependence of sound means that certain auditory messages must be scheduled simultaneously, which can lead to perceptual problems due to psychoacoustic phenomena. Furthermore, the combination of speech and nonspeech audio is examined; each presents its own problems of perceptibility in an acoustic environment composed of multiple auditory streams. The centralized audio presentation manager receives abstract parameterized message requests from the currently running programs, and attempts to create and present a sonic representation in the most perceptible manner through the use of a theoretically and empirically designed rule set.

Multiple presentation of mitochondrial disorders  

PubMed Central

The aim of this study was to assess the heterogeneous clinical presentations of children with mitochondrial disorders evaluated at a metabolic neurogenetic clinic. The charts of 36 children with highly suspected mitochondrial disorders were reviewed. Thirty one children were diagnosed as having a mitochondrial disorder, based on a suggestive clinical presentation and at least one of the accepted laboratory criteria; however, in five children with no laboratory criteria the diagnosis remained probable. All of the patients had nervous system involvement. Twenty seven patients also had dysfunction of other systems: sensory organs in 15 patients, cardiovascular system in five, gastrointestinal system in 20,urinary system in four, haematopoietic system in four, and endocrine system in nine. The clinical presentation was compatible with an established syndrome in only 15 children. Severe lactic acidosis or ragged red muscle fibres were encountered in very few patients. These results suggest that mitochondrial disorders should be evaluated in children presenting with a complex neurological picture or multisystem involvement.?

Detailed structure of spinning detonation in a circular tube  

SciTech Connect

A single spinning detonation wave propagating in a circular tube, discovered experimentally in 1926, is simulated three-dimensionally with a detailed chemical reaction mechanism. The detonation front obtained numerically rotates periodically with a Mach leg, whiskers, and a transverse detonation. A long pressure trail, which is distributed from the transverse detonation to downstream, was reproduced, clearly showing that the pressure trail also spins synchronously with the transverse detonation. The formation of an unburned gas pocket behind the detonation front was not observed in the present simulations because the rotating transverse detonation completely consumed the unburned gas. The calculated profiles of instantaneous OH mass fraction have a keystone shape behind the detonation front. The numerical results for pitch, track angle, Mach stem angle, and incident shock angle on the tube wall agree well with the experimental results. (author)

Adult Presentation of PHACES Syndrome  

PubMed Central

Summary A significant percentage of children with hemangiomas may have PHACES syndrome which refers to the association of posterior fossa malformations, facial hemangiomas, arterial cerebrovascular abnormalities, cardiovascular anomalies, eye abnormalities and ventral defects like sternal clefting or supraumbilical raphe. A variety of factors have led to under diagnosis of PHACES syndrome in the past including lack of awareness and limited imaging modalities. Also, patients with PHACES syndrome with arterial cerebrovascular abnormalities can present with acute ischemic stroke. However, these patients usually present before one year of age. We describe a 29-year-old woman with no history of cerebrovascular disease who initially presented with symptoms of a stroke and was subsequently diagnosed to have PHACES syndrome exhibiting an array of multiple unusual imaging findings. We also discuss the current literature and recommendations about PHACES syndrome.

Organizing MHC Class II Presentation  

PubMed Central

Major histocompatibility complex (MHC) class II molecules are ligands for CD4+ T cells and are critical for initiating the adaptive immune response. This review is focused on what is currently known about MHC class II organization at the plasma membrane of antigen presenting cells and how this affects antigen presentation to T cells. The organization and diffusion of class II molecules have been measured by a variety of biochemical and microscopic techniques. Membrane lipids and other proteins have been implicated in MHC class II organization and function. However, when compared with the organization of MHC class I or TCR complexes, much less is known about MHC class II. Since clustering of T cell receptors occurs during activation, the organization of MHC molecules prior to recognition and during synapse formation may be critical for antigen presentation.

Autophagy Host defenses against microorganisms include targeting the pathogens for degradation in acidic lysosomal organelles, generating adaptive immune responses by orchestrating successful antigen presentation and maintenance of cellular homeostasis. Infected cells employ evolutionarily-conserved cellular autophagic machinery that is normally used in the degradation of intracellular protein aggregates and damaged organelles to accomplish these responses. This catabolic pathway, known as autophagy, helps cells survive under starvation conditions by restoring nutrient balance.

Sheehan's syndrome presenting as psychosis: a rare clinical presentation  

PubMed Central

Sheehan's syndrome (SS) refers to the occurrence of varying degree of hypopituitarism after parturition (1). It is a rare cause of hypopituitarism in developed countries owing to advances in obstetric care and its frequency is decreasing worldwide. However, it is still frequent in underdeveloped and developing countries. Sheehan's syndrome is often diagnosed late as it evolves slowly (2,3). Reports of psychoses in patients with Sheehan's syndrome are rare. Herein, a case report of psychosis in a 31 year old woman who developed Sheehan's syndrome preceded by postpartum haemorrhage is presented. Treatment with thyroxine and glucocorticoids resulted in complete remission after attaining euthyroid and eucortisolemic state.

Detailed Experimental Data for CFD Code Validation  

NASA Technical Reports Server (NTRS)

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.

Plasma predictions: past, present and future  

NASA Astrophysics Data System (ADS)

Tools for predictions of plasma properties in the last 50 years have evolved from largely analytic representations, for example using Bessel functions, to the present methods, which extensively use computers. Furthermore, there is a marked unification of predictive capabilities, spanning the use of basic atomic and molecular data such as electron-atom cross-sections, leading to the calculation of transport coefficients such as thermal and electrical conductivities and finally to detailed predictions of plasma processing, e.g. the influence of fluxes on weld profiles in arc welding. Present calculations in the range of different directions are outlined, all likely to lead to new developments in the future. The examples are (1) predictions spanning collisionless to collision-dominated plasmas—such as are required for understanding the role of cathode voltages of non-thermionic cathodes. (2) Plasma chemistry predictions—such as are required to understand electrical breakdown in air to include the role of nitrogen metastables. (3) Predictions of the interactions of ion flow and insulating surfaces—such as could explain the existence of ball lightning. Finally, (4) the greater consideration of magnetic forces on astrophysical plasmas, which may explain the regular properties of the solar system.

Unusual presentation of metastatic adenocarcinoma  

PubMed Central

Background The most common tumours of the adrenal gland are adenoma, pheochromocytoma, adrenocortical carcinoma, and metastases. Although the imaging features of these tumours are established, the imaging characteristics of uncommon adrenal masses are less well known. In patients with extradrenal tumour, incidental discovery of an adrenal mass necessitates excluding the possibility of metastatic malignancy. Case presentation A 52 year-old female was diagnosed with oesophageal adenocarcinoma and treated with oesophagectomy and adjuvant chemotherapy. Sixteen months later on staging CT scan a 2 × 2 cm adrenal mass was detected, which increased in size over a period of time to 3 × 3 cm in size. Adrenalectomy was performed and histological examination revealed metastatic adenocarcinoma within an adrenal adenoma. Conclusion The present case highlights the unusual behaviour of an oesophageal adenocarcinoma causing metastasis to an adrenocortical adenoma.

Intrapartum management of breech presentation.  

PubMed

Breech presentation is associated with significantly increased risk of perinatal morbidity and mortality. Most of the morbidity and mortality associated with breech delivery results from cord compression, nuchal arm, and difficulty in the delivery of the aftercoming head. Routine cesarean delivery of term breeches may not be an unreasonable option, according to many physicians. In our view, the best results for vaginal delivery are achieved using strict protocols that select term or near-term frank breeches of normal size and with proper demonstration of pelvic dimensions. Serious consideration for cesarean delivery should be given to all others. If cesarean delivery is chosen for the very low-birth-weight infant, it is important to use a vertical uterine incision and appropriate anesthesia techniques to ensure atraumatic delivery and optimize out-come. ECV is safe and effective for reducing the incidence of breech presentation but will have little, if any, impact on the overall cesarean delivery rate. PMID:8689802

Remembering the Details: Effects of Emotion  

PubMed Central

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.

Antigen presentation in celiac disease  

PubMed Central

Celiac disease is caused by an inappropriate immune response to ingested gluten proteins. As a dietary antigen, gluten undergoes extensive but incomplete proteolytic digestion in the intestinal lumen. The resultant peptide fragments of gluten require deamidation, but not necessarily further intracellular processing for presentation. Recent studies reveal why the disease associated HLA-DQ2 molecule is particularly suited for binding proline-rich gluten peptides. In comparison, DQ8 exhibits different binding characteristics, which may explain the lesser risk for disease in association with this molecule.

Hereditary disorders presenting with urticaria.  

PubMed

The latest clinical guideline includes three major hereditary disorders presenting with urticaria: urticaria pigmentosa (mastocytosis), hereditary angioedema, and cryopyrin-associated periodic syndromes. Understanding the genetic cause and the consequent pathogenesis of such disorders helps in providing disease-specific essential therapeutic regimens. In recent years, distinct hereditary autoinflammatory syndromes with cold urticaria have been reported: NLRP12-associated periodic syndrome, and PLCG2-associated antibody deficiency and immune dysregulation. Moreover, some familial cases with urticaria still remain to be genetically defined. Rapid progress in genetic analysis and further insights into undefined hereditary urticaria promise the development of novel therapeutics in the near future. PMID:24262697

Tonsilloliths are calcifications within a tonsillar crypt, involve primarily the palatine tonsil caused by dystrophic calcification as a result of chronic inflammation. Tonsilloliths are very uncommon and are microscopic. Tonsillar concretions sometimes produce symptoms which include non-specific chronic halitosis, irritable cough, dysphagia, otalgia and foreign body-like sensation or foul taste. Patients with tonsillolithiasis may also be asymptomatic, with their lesions being discovered incidentally on panoramic radiographs. This article presents an unusual case of multiple bilateral and asymptomatic tonsilloliths which were found during a routine panoramic radiographic examination.

Tonsilloliths are calcifications within a tonsillar crypt, involve primarily the palatine tonsil caused by dystrophic calcification as a result of chronic inflammation. Tonsilloliths are very uncommon and are microscopic. Tonsillar concretions sometimes produce symptoms which include non-specific chronic halitosis, irritable cough, dysphagia, otalgia and foreign body-like sensation or foul taste. Patients with tonsillolithiasis may also be asymptomatic, with their lesions being discovered incidentally on panoramic radiographs. This article presents an unusual case of multiple bilateral and asymptomatic tonsilloliths which were found during a routine panoramic radiographic examination. PMID:24298535

Leriche's syndrome presenting as sciatica.  

PubMed

Sciatica is a common cause of lower back pain and claudication; the true etiology is often misunderstood. We report a case of a 53-year-old man who presented with sciatica. Clinically, there was evidence of aortoiliac obstruction with the absence of femoral pulses and a vascular index of 0.4 at the ankle. An aortogram revealed a very tight irregular stenosis of the aortic bifurcation and bilateral proximal common iliac arteries. After resection of diseased aorta, an aortoiliac graft was inserted. The symptoms subsided. This case highlights the importance of performing a complete vascular evaluation in patients diagnosed with sciatica. PMID:20488654

Neuromodulation: present and emerging methods  

PubMed Central

Neuromodulation has wide ranging potential applications in replacing impaired neural function (prosthetics), as a novel form of medical treatment (therapy), and as a tool for investigating neurons and neural function (research). Voltage and current controlled electrical neural stimulation (ENS) are methods that have already been widely applied in both neuroscience and clinical practice for neuroprosthetics. However, there are numerous alternative methods of stimulating or inhibiting neurons. This paper reviews the state-of-the-art in ENS as well as alternative neuromodulation techniques—presenting the operational concepts, technical implementation and limitations—in order to inform system design choices.

Constrictive pericarditis presenting as chylothorax.  

PubMed

Chylothorax is a rare clinical condition that can be attributed to a damaged thoracic duct. The condition is suggested by aspiration of milky white fluid from the pleural cavity and is commonly associated with either malignant diseases or trauma (e.g. cardiothoracic surgery). We present the case of a 15-year-old boy with chylothorax, whose effusion was due to constrictive pericarditis. The definitive treatment of chylothorax involves identification and management of the underlying pathology. We suggest that when dealing with cases of chylothorax, constrictive pericarditis should be considered among the causes. PMID:21947162

Effect of Anticipatory Guidance Presentation Methods on the Knowledge and Attitude of Pregnant Women Relative to Maternal, Infant and Toddler's Oral Health Care  

PubMed Central

Objective: The prenatal period is the best time for health interventions. The aim of this study was to evaluate the effects of different methods of anticipatory guidance presentation on the change of knowledge and attitude of pregnant women regarding oral healthcare in the mother, infant and toddler. Materials and Methods: In this quasi-experimental study, 90 pregnant women attended one health center in Zahedan, Iran; they were divided into direct intervention, indirect intervention and control groups. A self-reported questionnaire was completed before intervention. The guidance was presented to the direct intervention group, by PowerPoint and to the indirect group by pamphlet. Immediately after the intervention, the questionnaire was completed by intervention groups and two months later by all participants. Difference in the scores at start and end was calculated. Mann-Whitney, Kruskal-Wallis with Dunn’s post hoc and Friedman with K-W post-hoc tests were used for statistical analysis. The data was analyzed using SPPS version 19 software at a significance level of 0.05. Results: The change in scores of knowledge relevant to maternal, infant and toddler’s oral health and attitude toward maternal oral healthcare had significant differences in the three studied groups (P>0.05), The changes of scores in the four mentioned variables in the intervention groups were significantly higher than controls. In comparison between the intervention groups, the change in score of knowledge about maternal oral healthcare was significantly higher in the direct intervention group (P=0.023). Conclusion: Anticipatory guidance presentation led to change in the score of knowledge about maternal, infant and toddler’s oral health and attitude towards maternal oral health in comparison to no presentation. The direct presentation had superiority over indirect in increasing knowledge about maternal oral healthcare.

The Observing Programme, Present Status  

NASA Astrophysics Data System (ADS)

Corotweeks after Corotweeks, the observing programme has become more and more precise. Requirements from the Core Programme, as described in the Scientific Specification document, and recalled in chapter II of this volume lead to select first the long runs. Some delay in the launch date has lead to modify the programme for the first semester, substituting two "Initial runs" to a long run in the anticentre direction. This paper presents the status of the choices made by the Scientitific Committee till its 19th session on June 2006 in Nice. After the basic choice of the selected regions around principal targets, the successive pointings (Runs) are presented, in a sort of chronological order: - The two initial runs - The first centre pointings : LRc1 and SRc1 - The first anticentre pointings: LRa1 and SRa1 - The second centre pointing: LRc2, still to be tuned (SRc2 is not yet chosen) - The second anticentre pointing : LRa2, still to be confirmed by the exoplanet programme (SRa2 is not yet chosen). The following ones have not been decided yet. It is clear that the first results from space may lead to slight modifications, and orient differently the choices for the later phases.

Configuration Aerodynamics: Past - Present - Future  

NASA Technical Reports Server (NTRS)

The Configuration Aerodynamics (CA) element of the High Speed Research (HSR) program is managed by a joint NASA and Industry team, referred to as the Technology Integration Development (ITD) team. This team is responsible for the development of a broad range of technologies for improved aerodynamic performance and stability and control characteristics at subsonic to supersonic flight conditions. These objectives are pursued through the aggressive use of advanced experimental test techniques and state of the art computational methods. As the HSR program matures and transitions into the next phase the objectives of the Configuration Aerodynamics ITD are being refined to address the drag reduction needs and stability and control requirements of High Speed Civil Transport (HSCT) aircraft. In addition, the experimental and computational tools are being refined and improved to meet these challenges. The presentation will review the work performed within the Configuration Aerodynamics element in 1994 and 1995 and then discuss the plans for the 1996-1998 time period. The final portion of the presentation will review several observations of the HSR program and the design activity within Configuration Aerodynamics.

Presentation Extensions of the SOAP  

NASA Technical Reports Server (NTRS)

A set of extensions of the Satellite Orbit Analysis Program (SOAP) enables simultaneous and/or sequential presentation of information from multiple sources. SOAP is used in the aerospace community as a means of collaborative visualization and analysis of data on planned spacecraft missions. The following definitions of terms also describe the display modalities of SOAP as now extended: In SOAP terminology, View signifies an animated three-dimensional (3D) scene, two-dimensional still image, plot of numerical data, or any other visible display derived from a computational simulation or other data source; a) "Viewport" signifies a rectangular portion of a computer-display window containing a view; b) "Palette" signifies a collection of one or more viewports configured for simultaneous (split-screen) display in the same window; c) "Slide" signifies a palette with a beginning and ending time and an animation time step; and d) "Presentation" signifies a prescribed sequence of slides. For example, multiple 3D views from different locations can be crafted for simultaneous display and combined with numerical plots and other representations of data for both qualitative and quantitative analysis. The resulting sets of views can be temporally sequenced to convey visual impressions of a sequence of events for a planned mission.

Cutaneous sporotrichosis: unusual clinical presentations.  

PubMed

Three unusual clinical forms of sporotrichosis described in this paper will be a primer for the clinicians for an early diagnosis and treatment, especially in its unusual presentations. Case 1, a 52-year-old man, developed sporotrichosis over pre-existing facial nodulo-ulcerative basal cell carcinoma of seven-year duration, due to its contamination perhaps from topical herbal pastes and lymphocutaneous sporotrichosis over right hand/forearm from facial lesion/herbal paste. Case 2, a 25-year-old woman, presented with disseminated systemic-cutaneous, osteoarticular and possibly pleural (effusion) sporotrichosis. There was no laboratory evidence of tuberculosis and treatment with anti-tuberculosis drugs (ATT) did not benefit. Both these cases were diagnosed by histopathology/culture of S. schenckii from tissue specimens. Case 3, a 20-year-old girl, had multiple intensely pruritic, nodular lesions over/around left knee of two-year duration. She was diagnosed clinically as a case of prurigo nodularis and histologically as cutaneous tuberculosis, albeit, other laboratory investigations and treatment with ATT did not support the diagnosis. All the three patients responded well to saturated solution of potassium iodide (SSKI) therapy. A high clinical suspicion is important in early diagnosis and treatment to prevent chronicity and morbidity in these patients. SSKI is fairly safe and effective when itraconazole is not affordable/available. PMID:20445301

Detailed simulation of morphodynamics: 1. Hydrodynamic model  

NASA Astrophysics Data System (ADS)

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.

Detailed Burnup Calculations for Testing Nuclear Data  

NASA Astrophysics Data System (ADS)

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.

Neurocysticercosis presenting as pseudobulbar palsy  

PubMed Central

Neurocysticercosis (NCC) is the most common helminthic infestation of the central nervous system (CNS) and a leading cause of acquired epilepsy worldwide. The common manifestations of NCC are seizures and headache. The NCC as a cause of pseudobulbar palsy is very unusual and not reported yet in the literature. A pseudobulbar palsy can occur in any disorder that causes bilateral corticobulbar disease. The common etiologies of pseudobulbar palsy are vascular, demyelinative, or motor neuron disease. We report a 38-year-old female patient who presented with partial seizures and pseudobulbar palsy. The MRI brain showed multiple small cysts with scolex in both the cerebral hemispheres and a giant intraparenchymal cyst. Our patient responded well to standard treatment of neurocysticercosis and antiepileptics.

Opposing views on contraceptives presented.  

PubMed

This article presents two opposing views on the importance of artificial contraceptives. It is noted that in the April 19 issue of the Manila Bulletin, Ms. Ethel Soliven wrote in her column that the position of the Catholic Church on artificial contraceptives is standing in the way of success of the Philippine family planning campaign. To this effect, Sister Mary Pilar Versoza of the Religious of the Good Shepherd, sent a letter of rebuttal saying that the church has never been remiss in emphasizing the true meaning of sexual act, love and relationship, marriage, and family responsibilities. Sister Pilar contended that ligation and condoms do not solve husbands¿ selfishness. In response, Soliven argued in another issue of the Manila Bulletin that she believes in the need to provide access to artificial contraceptives. Soliven asserted that destitute couples who cannot provide their families with even the barest necessities of life should be provided with the means with which to prevent unwanted pregnancies.

Hodgkin's Lymphoma Presenting as Alopecia.  

PubMed

Alopecia is a rare manifestation of Hodgkin's disease. It may be due to follicular destruction due to direct infiltration by the disease, or it may be a secondary or paraneoplastic manifestation. In this patient, hair loss, diffuse yperpigmentation, and generalized itching preceded other manifestations of the disease. The pattern of hair loss was diffuse and generalized in nature involving scalp, eyebrows, axilla, and groin. Subsequently, the patient was diagnosed to be a case of Hodgkin's lymphoma, based on clinical and histopathological features. Earlier reports on alopecia accompanying Hodgkin's disease have also been discussed. This case highlights the importance of keeping a high suspicion of an underlying malignancy in patients presenting with such cutaneous manifestations. PMID:23180928

Integrons: past, present, and future.  

PubMed

Integrons are versatile gene acquisition systems commonly found in bacterial genomes. They are ancient elements that are a hot spot for genomic complexity, generating phenotypic diversity and shaping adaptive responses. In recent times, they have had a major role in the acquisition, expression, and dissemination of antibiotic resistance genes. Assessing the ongoing threats posed by integrons requires an understanding of their origins and evolutionary history. This review examines the functions and activities of integrons before the antibiotic era. It shows how antibiotic use selected particular integrons from among the environmental pool of these elements, such that integrons carrying resistance genes are now present in the majority of Gram-negative pathogens. Finally, it examines the potential consequences of widespread pollution with the novel integrons that have been assembled via the agency of human antibiotic use and speculates on the potential uses of integrons as platforms for biotechnology.

Functional membranes. Present and future  

NASA Technical Reports Server (NTRS)

The present situation and the future development of the functional membrane are discussed. It is expected that functional membranes will play increasingly greater roles in the chemical industry of the coming decade. These membranes are formed from polymer films, liquid membranes or bilayer membranes. The two most important technologies based on the polymeric membrane are reverse osmosis and ion exchange. The liquid membrane is used for separation of ionic species; an extension of the solvent extraction process. By using appropriate ligands and ionophores, highly selective separations are realized. The active transport is made possible if the physical and chemical potentials are applied to the transport process. More advanced functional membranes may be designed on the basis of the synthetic bilayer membrane.

Adrenomyeloneuropathy Presenting With Adrenal Insufficiency  

PubMed Central

Adrenomyeloneuropathy (AMN), one of the variants of X-linked adrenoleukodystrophy (ALD), is inherited peroxisomal disorder associated with the accumulation of very long chain fatty acids (VLCFA). AMN is characterized primarily by involvements of long ascending and descending tracts of the spinal cord and peripheral neuropathy, which leads to spastic paraparesis and urinary and erectile dysfunction. We experienced the AMN case of a 33-year-old man presenting bilateral progressive spastic paraparesis, impotence and urge incontinence with primary adrenal failures, as confirmed by increased serum of VLCFA concentrations. Considering that somatosensory evoked potentials in posterior tibial nerve was the only abnormal finding in electrophysiologic findings when compared with the severe spastic gait pattern shown, it is necessary to follow up with electrophysiologic studies.

PSYCHIATRY-PAST, PRESENT & FUTURE  

PubMed Central

An overview of psychiatry during the last three decades as practised in a general teaching hospital is presented. Psychiatry as an academic subject has matured tremendously during this period. The empirical treatments of the 1950s and the 1960s which evoke nostalgic memories, have been replaced by modern methods of treatment. However, there is a need to exercise caution against the blind acceptance of new and sophisticated research findings in biological psychiatry. Inspite of the bright future facing psychiatry, the identity of psychiatry as a medical discipline must be preserved at all cost. Psychiatrists should also realise the dangers of gradual fractionation and impersonalisation which threatens the speciality, and makes all possible efforts to prevent this.

Tritium practices past and present  

SciTech Connect

History of the production and use of tritium, as well as handling techniques, are reviewed. Handling techniques first used at Lawrence Livermore National Laboratory made use of glass vacuum systems and relatively crude ion chambers for monitoring airborne activity. The first use of inert atmosphere glove boxes demonstrated that uptake through the skin could be a serious personnel exposure problem. Growing environmental concerns in the early 1970's resulted in the implementation by the Atomic Energy Commission of a new criteria to limit atmospheric tritium releases to levels as low as practicable. An important result of the new criteria was the development of containment and recovery systems to capture tritium rather than vent it to the atmosphere. The Sandia National Laboratories, Livermore, Tritium Research Laboratory containment and decontamination systems are presented as a typical example of this technology. The application of computers to control systems is expected to provide the greatest potential for change in future tritium handling practices.

Exercise suppresses macrophage antigen presentation.  

PubMed

This study determined the effects of exercise on the ability of macrophages (Mphi) to present antigen to T cells. Pathogen-free male Balb/c mice (8 +/- 2 wk of age) were randomly assigned to either home cage control, moderate exercise (Mod; 18 m/min, 5% grade, 0.5 h/day), exhaustive exercise (Exh, 18-30 m/min, 3 h/day), or treadmill control groups. The mice underwent treatments for 4 days during peritoneal thioglycolate inflammation. Peritoneal Mphi were harvested, purified, and incubated with chicken ovalbumin (C-OVA; 0-10 mg/ml) for 18 h. Mphi were then cocultured with C-OVA-specific T cells for 48 h, and the supernatants were analyzed via ELISA for interleukin-2 as an indication of Mphi antigen presentation (AP). Exh exhibited suppressed ( approximately 25-34%) Mphi AP across a wide range of C-OVA doses when measured immediately, 3, and 24 h postexercise. In contrast, Mod had reduced Mphi AP only at 3 h postexercise. Mphi AP was also lower in the treadmill control (4-27%) compared with the home cage control group, but was significantly higher than Exh. The reduction in Mphi AP was not due to exercise-induced differences in Mphi number, percentage, or expression of intercellular adhesion molecule-1, B7-2, or major histocompatability complex II, molecules important in AP. In conclusion, our data lend evidence that may help explain the increased incidence of infection observed after prolonged exhaustive exercise or overtraining. PMID:10601175

Teratology - past, present and future.  

PubMed

Teratology is the science that studies the causes, mechanisms, and patterns of abnormal development. The authors present an updated overview of the most important milestones and stages of the development of modern teratology. Development of knowledge and society led to the recognition that causes of congenital developmental disorders (CDDs) might be caused by various mechanical effects, foetal diseases, and retarded or arrested development of the embryo and foetus. Based on the analysis of the historical development of hypotheses and theories representing a decisive contribution to this field, we present a survey of the six Wilson's fundamental principles of teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realise that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in CDDs. Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called "low dose-hypothesis", particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural. PMID:23554558

Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called “low dose-hypothesis”, particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural.

Detailed mechanism of toluene oxidation and comparison with benzene  

NASA Technical Reports Server (NTRS)

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.

Locating Pd in Transformers through Detailed Model and Neural Networks  

NASA Astrophysics Data System (ADS)

In a power transformer as one of the major component in electric power networks, partial discharge (PD) is a major source of insulation failure. Therefore the accurate and high speed techniques for locating of PD sources are required regarding to repair and maintenance. In this paper an attempt has been made to introduce the novel methods based on two different artificial neural networks (ANN) for identifying PD location in the power transformers. In present report Fuzzy ARTmap and Bayesian neural networks are employed for PD locating while using detailed model (DM) for a power transformer for simulation purposes. In present paper PD phenomenon is implemented in different points of transformer winding using threecapacitor model. Then impulse test is applied to transformer terminals in order to use produced current in neutral point for training and test of employed ANNs. In practice obtained current signals include noise components. Thus the performance of Fuzzy ARTmap and Bayesian networks for correct identification of PD location in a noisy condition for detected currents is also investigated. In this paper RBF learning procedure is used for Bayesian network, while Markov chain Monte Carlo (MCMC) method is employed for training of Fuzzy ARTmap network for locating PD in a power transformer winding and results are compared.

Routing the asteroid surface vehicle with detailed mechanics  

NASA Astrophysics Data System (ADS)

The motion of a surface vehicle on/above an irregular object is investigated for a potential interest in the insitu explorations to asteroids of the solar system. A global valid numeric method, including detailed gravity and geomorphology, is developed to mimic the behaviors of the test particles governed by the orbital equations and surface coupling effects. A general discussion on the surface mechanical environment of a specified asteroid, 1620 Geographos, is presented to make a global evaluation of the surface vehicle's working conditions. We show the connections between the natural trajectories near the ground and differential features of the asteroid surface, which describes both the good and bad of typical terrains from the viewpoint of vehicles' dynamic performances. Monte Carlo simulations are performed to take a further look at the trajectories of particles initializing near the surface. The simulations reveal consistent conclusions with the analysis, i.e., the open-field flat ground and slightly concave basins/valleys are the best choices for the vehicles' dynamical security. The dependence of decending trajectories on the releasing height is studied as an application; the results show that the pole direction (where the centrifugal force is zero) is the most stable direction in which the shift of a natural trajectory will be well limited after landing. We present this work as an example for pre-analysis that provides guidance to engineering design of the exploration site and routing the surface vehicles.

Detailed Cretaceous reconstruction model for the South Atlantic  

NASA Astrophysics Data System (ADS)

The temporal resolution of plate reconstruction models linearily depends on the frequency at which the geomagnetic field flipped its polarity. Accordingly, past plate motions during the long period of the Cretaceous normal superchron (CNS, 83.5-120.6 Ma) is poorly resolved. Recent findings on the behaviour of the geomagnetic field during the CNS (Granot et al., 2012) provide two new time markers that may be used to define internal isochrons within the Quiet zones. Here we present preliminary results of the first attempt to utilize these magnetic anomalies (Q2 and Q1, 108 and 92 Myr ago, respectively) in the South Atlantic Cretaceous Quiet zones. We have calculated six sets of finite rotation parameters for Anomalies M4 (126.5 Ma), M0 (120.6 Ma), Q2 (108 Ma), Q1 (92 Ma), C34 (83.5 Ma) and C33r (79 Ma) that illuminate in detail the break-up of Africa and South America. We confirm the validity of the results by tracing the fracture zones with synthetic flowlines and predictions of magnetic anomalies location outside of our studied area. Based on these new rotation parameters, we present kinematic analysis that shed new light on the major changes in plate motion that took place in the South Atlantic during the Cretaceous.
