  2. Science as theater, theater as science

    Beginning with Bertold Brecht's "Galileo" in 1942 and Friedrich Dürrenmatt's "The Physicists" in 1962, physics and other sciences have served a number of dramatists as backdrops for the exposition of existential problems, as well as the provision of entertainment. Michael Frayn's 1998 play "Copenhagen" broke new ground by giving a central role to the presentation of scientific substance and ideas and to the examination of recent controversial and emotionally charged events in the history of science and of the "real world". A rash of "science plays" erupted. How should we physicists react to this development? Surely, it can be argued, any exposure of science to the public is better than none and will help break down the barriers between the "two cultures". But what if the science or the scientists are badly misrepresented or the play is a weapon to strip science of its legitimacy and its claims to reality and truth? After reviewing a half dozen of the new plays, I conclude that "Copenhagen", though flawed, is not only the best of show, but a positive, even admirable endeavor. The contributions of Bohr, Heisenberg, Born, Schrödinger, and other scientists and their interactions in the golden years of the creation of quantum mechanics are accurately and thrillingly rendered. There may be no better non-technical exposition of complementarity and the uncertainty principle than the one that Frayn puts into the mouths of Bohr and Heisenberg. The treatment of the history of the atomic bomb and Heisenberg's role in Germany's failure to achieve a bomb is another matter. Frayn can also be criticized for applying uncertainly and complementarity to the macroscopic world and, in particular, to human interactions, thereby giving some aid and comfort to the post-modernists. These reservations aside, Copenhagen is a beautiful contribution to the appreciation of science.

    Theater, music, dance, the literary and the visual arts can convey the joys and controversies of science. We describe a program at the Graduate Center entitled Science & the Arts which is designed to communicate to the public the excitement and wonder of science, technology, engineering and mathematics. Over the past few years there have been major successes in communicating science to the public through the arts. This is especially evident in theater, film and opera with such recent plays as Copenhagen, the Oscar winning film A Beautiful Mind and the opera Doctor Atomic at the Met. The performance series Science & the Arts has been developed and tested at the Graduate Center of the City University of New York (CUNY) in mid-Manhattan for more than nine years, see http://web.gc.cuny.edu/sciart/ . We have established working relationships with actors, playwrights, dancers, choreographers, musicians, composers, artists and scientists who work at the intersection of science and the arts. In this presentation we will illustrate many of our collaborations in theater, dance, music and art. Faculty members, professionals and students from the university, other educational institutions, museums, theaters and government laboratories as well as the public with an interest science and arts programs should find this presentation of particular interest.

  14. The Use of Theater and the Performing Arts in Science Education and the Teaching of History

    Science.gov (United States)

    Schwartz, Brian

    2015-03-01

    Over the past 15 years there has been a surge in the general field of the interaction of STEM and the arts including theatre, music dance and the visual arts leading to STEAM. There seems to be no limits to the amount of creativity and diversity of subject matter especially in areas of biography, major science events, scientific and technical innovation, the benefits and dangers of modern science, and science as metaphor. For the past 15 years, I and my colleagues have been running a science outreach series under the title Science & the Performing Arts at the Graduate Center of the City University of New York. The objective is to bring science to students and the public in ways that are engaging, instructive, and artistic and always, content-driven: the medium is the arts; the message is the joy of science. This has resulted in over 120 science and performing arts programs which have been documented on the website http://sciart.commons.gc.cuny.edu/ . The author co-taught a course titled Staging Science, http://sciart.commons.gc.cuny.edu/staging-science/outline-of-the-course-staging-science/ with Marvin Carlson, Professor of Theatre at CUNY. An excellent book, Science on Stage: From Doctor Faustus to Copenhagen by Kirsten Shepherd-Barr, can be used to develop a customized courses on Science, Theatre and History for both science and non-science majors. The book's appendix includes an annotated listing of plays on such subjects as quantum mechanics, chaos theory, evolution, genetics and morality and responsibility. The talk will include many examples how courses on science and theatre can actively engage students and enhance active participation and learning.

    strategies of the 1950s and 20th Century-Fox’s vision of the possibilities of electronic delivery for motion picture exhibition. This paper aims to shed more light in one of the less known chapters of the history of motion picture presentation in the US, whose renewed interest today is closely linked to the digital media revolution. As the exhibition market transitions to digital delivery, the deployment of alternative contents, including gaming, sporting events and concerts, is converting the cinema screen into a multimedia center, a giant high definition television screen. How far is this idea from the theater television concept of the 1950s which Spyros Skouras qualified as “the greatest stimulant our industry has had since the advent of sound” ?

    X-rays and electrons are two of the most fundamental probes of matter. When the Linac Coherent Light Source (LCLS), the world’s first x-ray free electron laser, began operation in 2009, it transformed ultrafast science with the ability to generate laser-like x-ray pulses from the manipulation of relativistic electron beams. This document describes a similar future transformation. In Transmission Electron Microscopy, ultrafast relativistic (MeV energy) electron pulses can achieve unsurpassed spatial and temporal resolution. Ultrafast temporal resolution will be the next frontier in electron microscopy and can ideally complement ultrafast x-ray science done with free electron lasers. This document describes the Grand Challenge science opportunities in chemistry, material science, physics and biology that arise from an MeV ultrafast electron diffraction & microscopy facility, especially when coupled with linac-based intense THz and X-ray pump capabilities.

    2017-12-01

    A new Arts/Lab Student Residence program was developed at the University of Michigan that brings artists into a research lab. Science and Engineering undergraduate and graduate students working in the lab describe their research and allow the artists to shadow them to learn more about the work. The Arts/Lab Student Residencies are designed to be unique and fun, while encouraging interdisciplinary learning and creative production by exposing students to life and work in an alternate discipline's maker space - i.e. the artist in the engineering lab, the engineer in the artist's studio or performance space. Each residency comes with a cash prize and the expectation that a work of some kind will be produced as a response to experience. The Moldwin Prize is designed for an undergraduate student currently enrolled in the Penny W. Stamps School of Art & Design, the Taubman School of Architecture and Urban Planning or the School of Music, Theatre and Dance who is interested in exchange and collaboration with students engaged in research practice in an engineering lab. No previous science or engineering experience is required, although curiosity and a willingness to explore are essential! Students receiving the residency spend 20 hours over 8 weeks (February-April) participating with the undergraduate research team in the lab of Professor Mark Moldwin, which is currently doing work in the areas of space weather (how the Sun influences the space environment of Earth and society) and magnetic sensor development. The resident student artist will gain a greater understanding of research methodologies in the space and climate fields, data visualization and communication techniques, and how the collision of disciplinary knowledge in the arts, engineering and sciences deepens the creative practice and production of each discipline. The student is expected to produce a final work of some kind within their discipline that reflects, builds on, explores, integrates or traces their

    Full Text Available The bibliometric characteristics of electronic journals (e-journals covering the field of information science have been studied. Twenty-eight e-journals were identified and ranked by number of articles on the subject they published. A Bradford plot revealed that the core is not well developed yet, but it will likely contain six journals. The publication of information science articles in e-journals began modestly in 1995 with 26 articles, but it has risen to approximately 250 articles per year. The most prolific authors are identified. The vast majority of them are located in the United States or United Kingdom. Only 26 articles have authors from more than one country, showing that electronic technology has not yet strongly influenced international collaboration. About 2/3 of the articles originate in academic institutions. Common topics of e-journal articles in information science include electronic information, electronic publishing, virtual (digital libraries, information search and retrieval, and use of the Internet. Seven online databases cover these e-journals; Information Science Abstracts is the only one to cover all 28 journals, and it has the highest number of abstracts from them - over 1,100.

Such publications are important for the quantity and the diversity, revealing not only the place occupied by the theater in the capital, but also for the recognition of the press as a means of disclosure of plays, public education and opinion, artist projection, etc, not to mention personal affairs and requests, and the exchange of favors among managers and journalists. Even more, the press production of the dramatic amateurs clubs demonstrate the understanding of its role in the dissemination of ways to act and think beyond the stage and in the everyday life.

    Dastidar, P.R.

    1979-01-01

    Electronics plays a vital role in the field of nuclear research and industry. Nuclear instrumentation and control systems rely heavily on electronics for reliable plant operation and to ensure personnel safety from harmful radiations. Rapid developments in electronics have resulted in the gradual phasing out of pneumatic instruments and replacement by solid-state electronic systems. On-line computers are now being used extensively for centralised monitoring and control of large nuclear plants. The paper covers the following main topics: (i) radiation detection and measurement, (ii) systems for nuclear research and design, (iii) nuclear reactor control and safety systems and (iv) modern trends in reactor control and nuclear instrumentation systems. The methods for radiation detection, ionization chambers, self-powdered detectors and semiconductor detectors are discussed in brief, followed by the description of the electronic systems commonly used in nuclear research, namely the pulse height, multichannel, correlation and fourier analysers. NIM and CAMAC, the electronic system standards used in nuclear laboratories/industries are also outlined. Electronic systems used for nuclear reactor control, safety, reactor core monitoring, failed fuel detection and process control instrumentation, have been described. The application of computers to reactor control, plant data processing, better man-machine interface and the use of multiple computer systems for achieving better reliability have also been discussed. Micro-computer based instrumentation systems, computers in reactor safety and advanced nuclear instrumentation techniques are briefly illustrated. (auth.)

    The use of pump-probe experiments to study complex transient events has been an area of significant interest in materials science, biology, and chemistry. While the emphasis has been on laser pump with laser probe and laser pump with x-ray probe experiments, there is a significant and growing interest in using electrons as probes. Early experiments used electrons for gas-phase diffraction of photostimulated chemical reactions. More recently, scientists are beginning to explore phenomena in the solid state such as phase transformations, twinning, solid-state chemical reactions, radiation damage, and shock propagation. This review focuses on the emerging area of ultrafast electron microscopy (UEM), which comprises ultrafast electron diffraction (UED) and dynamic transmission electron microscopy (DTEM). The topics that are treated include the following: (1) The physics of electrons as an ultrafast probe. This encompasses the propagation dynamics of the electrons (space-charge effect, Child's law, Boersch effect) and extends to relativistic effects. (2) The anatomy of UED and DTEM instruments. This includes discussions of the photoactivated electron gun (also known as photogun or photoelectron gun) at conventional energies (60-200 keV) and extends to MeV beams generated by rf guns. Another critical aspect of the systems is the electron detector. Charge-coupled device cameras and microchannel-plate-based cameras are compared and contrasted. The effect of various physical phenomena on detective quantum efficiency is discussed. (3) Practical aspects of operation. This includes determination of time zero, measurement of pulse-length, and strategies for pulse compression. (4) Current and potential applications in materials science, biology, and chemistry. UEM has the potential to make a significant impact in future science and technology. Understanding of reaction pathways of complex transient phenomena in materials science, biology, and chemistry will provide fundamental

    Theater could be considered as a dramatic game and as an educational method, because it reaches the child as a whole, encompassing creativity and learning through entertainment. This article is a report of nursing students' experience in guiding children through theater in a public nursery located in the interior of São Paulo state. The objective was to report on the benefits of using theatre with children. The methodology to develop the study was a dialogue based on literature review articulated with the account of experience. It was concluded that theater can be used as an important educational tool, diversifying the way of teaching children, surpassing the simple pass on of knowledge, increasing involvement and integration.

    This paper illustrates different operating modes of the electron microscope and shows the image formation in an ideal microscope. Diffraction contrast is used in the study of crystal defects, such as dislocations and planar interfaces. Methods are surveyed which give at least a rudimentary image of the lattice and therefore make use of at least two interfering beams. Special attention is given to images which also carry structural information and therefore imply the use of many beams. The underlying theory is discussed as are the theories of Van Dyck, Spence and Cowley. These are illustrated by means of a number of recent case studies

    Full Text Available The aim of this study is to explore organizational policies and strategies regarding the institutional memory of Belgrade’s repertoire theaters. The concept of institutional (organizational memory has not been developed within the culture of memory theory. The role of theater in the culture of memory has been researched mostly through studies of its repertoire, corresponding to how theaters deal with issues of glory, guilt, or shame. This study explores how theaters rethink their own past and organizational culture, how they use their capacity for re-imagining themselves, for clarifying their role and function in different historical moments. The objective of this research is to identify the main institutional policies and types of strategies used for preserving institutional memory through key narratives of remembering, and key methods of inter-generational transfer. The sample comprises of four Belgrade-based public repertoire theaters: the Yugoslav Dramatic Theater (JDP, the Belgrade Dramatic Theater (BDP, Atelje 212, and Bitef Theater. Specific attention is given to the means of transmission, of individual (episodic memories into the collective consciousness, influencing organizational cultures and shaping a theater’s identity (semantic memory. Research has shown that there are important differences in active policies of preserving institutional memory among Belgrade’s theaters. Different organizational and programming strategies were implemented in order to safeguard institutional identity and memory, particularly in theaters with a permanent ensemble. The major difference is between theaters whose culture of memory might be called “non-existent” (Bitef, or “in storage” (BDP, and those succeeding in creating a functional memory (JDP, Atelje 212.

    Full Text Available We describe a teaching strategy, namely, the Great Theater of Physics, which stages a series of eight nontrivial demonstrations in the areas of mechanics, electricity, magnetism and waves. The aim was to generate feelings and attitudes that would promote the learning of physics, and to explore the motivation of Chemistry and Biology students towards classes in physics. The strategy was applied with a group of new students in Physics and Mathematics at the Faculty of Sciences at the Universidad Central de Venezuela. The method used was exploratory-descriptive.  Information was collected using a questionnaire with closed questions. In general, students from Physics and Mathematics disciplines experienced a significant increase in positive feelings towards physics after attending the theater; and negative feelings decreased, though not significantly. A greater percentage of women than men experienced an increase in positive feelings, though men experienced more intense positive feelings. This was not the case for negative feelings.

    Latina teen pregnancy rates continue to be a health disparity in the United States. This study evaluated a parenting intervention using interactive theater to facilitate Latino parent-adolescent communication about sexuality and pregnancy prevention. The intervention, conducted in Spanish and with teen actors, consisted of scenes involving the audience. Fifty-nine parents participated in this 3-month prospective study. Spanish measures of comfort with communication, general communication, and parent-child sexual communication were employed comparing paired t tests for each scale. Acceptability of the intervention was assessed and demonstrated. Eighty-six percent of parents used information from the performance to talk to their child. Improvements in general communication (p < .02), sexual communication (p < .001), and comfort (p < .001) occurred. Interactive theater is an innovative approach to facilitate Latino parent communication about sexuality and pregnancy prevention.

    To determine the safety of definitive in-theater facial fracture repair on American military personnel wounded during Operation Iraqi Freedom. A retrospective review of all patients with head and neck trauma treated at the 322nd Expeditionary Medical Group/Air Force Theater Hospital, Balad Air Base, Iraq, from May 7, 2005, through September 18, 2005, was performed. This study focused on the outcomes of wounded American military personnel whose facial fractures were definitively repaired in theater. The criteria used to determine candidacy for definitive in-theater facial fracture repair on American military personnel were (1) the fracture site was exposed through either a soft tissue wound or because of an adjacent surgical approach, (2) treatment would not delay evacuation from theater, and (3) treatment would allow the military member to remain in theater. From May 2005 to September 2005, 207 patients were taken to the operating room and required 388 procedures. A total of 175 patients (85%) were operated on for traumatic injuries, and 52 of these patients required open reduction and internal fixation (ORIF) of a facial fracture. Of the 52 patients who underwent an ORIF, 17 were American military personnel. Of the 17 American patients who were definitively treated for their facial fractures in theater, 16 were contacted and/or followed up on the global military medical database. None of these patients developed an Acinetobacter baumannii infection or had a complication caused by the definitive in-theater ORIF. The range of follow-up was 2 months to 11 months, with a mean of 8.3 months. Definitive repair of facial fractures with ORIF on American military personnel in theater is advised when the aforementioned criteria are observed. An otolaryngologist is a crucial member of the head and neck trauma team.

    The creative process is fun, complex, and sometimes frustrating, but it is critical to the future of our nation and progress in science, technology, engineering, mathematics (STEM), as well as other fields. Thus, we set out to see if implementing methods of active learning typical to the theater department could impact the creativity of senior capstone design students in the bioengineering (BE) department. Senior bioengineering capstone design students were allowed to self-select into groups. Prior to the beginning of coursework, all students completed a validated survey measuring engineering design self-efficacy. The control and experimental groups both received standard instruction, but in addition the experimental group received 1 h per week of creativity training developed by a theater professor. Following the semester, the students again completed the self-efficacy survey. The surveys were examined to identify differences in the initial and final self-efficacy in the experimental and control groups over the course of the semester. An analysis of variance was used to compare the experimental and control groups with p engineering design following the semester of creativity instruction. The results of this pilot study indicate that there is a significant potential to improve engineering students' creative self-efficacy through the implementation of a "curriculum of creativity" which is developed using theater methods.

    In the brief period between May 1978 and December 12, 1979, U.S. policy, and the policy of the NATO Alliance, toward theater nuclear forces (TNF) changed dramatically. The consequences of this change now dominate the political agenda in East-West (and West-West) relations. The ultimate outcome of the now renamed intermediate-range nuclear force (INF) debate will have far-reaching consequences for the future of the Atlantic Alliance. How did this issue emerge? Why did the US change its policy? How did it work with its Alliance to change NATO policy? These questions, among others, are now figuring in the debate. The answers to these questions are discussed in detail

    Soviet theater nuclear forces were a major pillar of Soviet superpower strength, rising sharply under Krushchev in the latter 1950s to their zenith under Brezhnev twenty years later. Most recently they have begun their decline under Gorbachev, and while not yet facing extinction, may be headed for a much reduced role under the new thinking in the USSR. This paper deals with the Soviet TNF in six periods of their life: The Post-war Stalin Period (1945-1953), the Post-Stalin Period (1953-1955), The Transition Period (1955-1959), The Period of Nuclear Revolution (1960-1964), The Period of Modern TNF Planning (1965-1980), and The Period of Non-nuclear Planning (1980-1987)

    The paper describes patterns of electronic journal usage in health sciences libraries during the past decade. The paper presents a case study, documenting the pattern of acquisition, management, and usage at the Louis Calder Memorial Library of the University of Miami Miller School of Medicine. Health sciences journals were early to offer electronic alternatives to print. As a result, health sciences libraries, their patrons, and the public at large were early to embrace the new versions and continue to embrace the significant changes in scholarly communication they enable. Although the patterns of electronic journals among health sciences libraries and other special and academic libraries have similarities, they also have differences. Broad studies of electronic journals in non-health sciences libraries have been published, but a retrospective review of electronic journals in health sciences libraries has not.

    Full Text Available From 1948 to 2007, the academic community produced about a hundred titles of theses and dissertations on drama and theater, or made use of data from drama and theater for larger spheres of studies. The current article looked into identifying trends and points of emphasis, as the researches and studies progressed through roughly half a century of research production in the academic setting. Inductive in approach and tentative and exploratory in its analysis, the study identified four trends and points of emphasis in research production. In the fifties and sixties, the emphasis was more on studying the play text or drama; studies veered towards a literary reading and orientation. Eventually, this trend gave way to studying the larger phenomenon of mounting, and the mise en scéne and the spectator became additional units of concern for research. Studies began to have sections on props, costumes, and staging techniques. In the eighties, a larger concern for looking at theater as social production followed. Participant observation, field work and ethnography gave equal emphasis on the social context of theater. Marxism and other perspectives from the social sciences framed theater studies then; correlations between theater and society became useful. Towards the last decade of the century, theater studies aimed at a more conceptual approach, emphasizing core concepts like panata and other related or equivalent terms, elevating and defining the study of theater as a study of culture itself.

    The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

  10. The effect of electronic networking on preservice elementary teachers' science teaching self-efficacy and attitude towards science teaching

    Mathew, Nishi Mary

    Preservice elementary teachers' science teaching efficacy and attitude towards science teaching are important determinants of whether and how they will teach science in their classrooms. Preservice teachers' understanding of science and science teaching experiences have an impact on their beliefs about their ability to teach science. This study had a quasi-experimental pretest-posttest control group design (N = 60). Preservice elementary teachers in this study were networked through the Internet (using e-mail, newsgroups, listserv, world wide web access and electronic mentoring) during their science methods class and student practicum. Electronic networking provides a social context in which to learn collaboratively, share and reflect upon science teaching experiences and practices, conduct tele-research effectively, and to meet the demands of student teaching through peer support. It was hoped that the activities over the electronic networks would provide them with positive and helpful science learning and teaching experiences. Self-efficacy was measured using a 23-item Likert scale instrument, the Science Teaching Efficacy Belief Instrument, Form-B (STEBI-B). Attitude towards science teaching was measured using the Revised Science Attitude Scale (RSAS). Analysis of covariance was used to analyze the data, with pretest scores as the covariate. Findings of this study revealed that prospective elementary teachers in the electronically networked group had better science teaching efficacy and personal science teaching efficacy as compared to the non-networked group of preservice elementary teachers. The science teaching outcome expectancy of prospective elementary teachers in the networked group was not greater than that of the prospective teachers in the non-networked group (at p < 0.05). Attitude towards science teaching was not significantly affected by networking. However, this is surmised to be related to the duration of the study. Information about the

  16. On DESTINY Science Instrument Electrical and Electronics Subsystem Framework

    2009-01-01

    Future space missions are going to require large focal planes with many sensing arrays and hundreds of millions of pixels all read out at high data rates'' . This will place unique demands on the electrical and electronics (EE) subsystem design and it will be critically important to have high technology readiness level (TRL) EE concepts ready to support such missions. One such omission is the Joint Dark Energy Mission (JDEM) charged with making precise measurements of the expansion rate of the universe to reveal vital clues about the nature of dark energy - a hypothetical form of energy that permeates all of space and tends to increase the rate of the expansion. One of three JDEM concept studies - the Dark Energy Space Telescope (DESTINY) was conducted in 2008 at the NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. This paper presents the EE subsystem framework, which evolved from the DESTINY science instrument study. It describes the main challenges and implementation concepts related to the design of an EE subsystem featuring multiple focal planes populated with dozens of large arrays and millions of pixels. The focal planes are passively cooled to cryogenic temperatures (below 140 K). The sensor mosaic is controlled by a large number of Readout Integrated Circuits and Application Specific Integrated Circuits - the ROICs/ASICs in near proximity to their sensor focal planes. The ASICs, in turn, are serviced by a set of "warm" EE subsystem boxes performing Field Programmable Gate Array (FPGA) based digital signal processing (DSP) computations of complex algorithms, such as sampling-up-the-ramp algorithm (SUTR), over large volumes of fast data streams. The SUTR boxes are supported by the Instrument Control/Command and Data Handling box (ICDH Primary and Backup boxes) for lossless data compression, command and low volume telemetry handling, power conversion and for communications with the spacecraft. The paper outlines how the JDEM DESTINY concept

    Mali's branch of the International Planned Parenthood Federation has found a vehicle that effectively conveys the idea of family planning through the use of contraception, a method that blends the country's cultural heritage and modern technology. Despite becoming the first sub-Saharan francophone country to promote family planning, Mali only counted 1% of its population using a modern method of contraception. So with the aid of The Johns Hopkins University/Population COmmunication Services (JHU/PCS), the Association Malienne pour la Protection et la Promotion de la Famille (AMPPF) developed several programs to promote contraception, but none were more successful than the Koteba Project, which used Mali's traditional theater form to communicate the message. While comical, the Koteba generally deals with social issues -- it informs and entertains. This particular Koteba told the story of two government employees, one with two wives and many children, the other with one wife and few children. The first one sees nothing but family problems: fighting wives and delinquent children. The second one, who had used family planning, enjoys a peaceful home. Upon hearing of his friend's successes with family planning, the tormented government employee becomes convinced of its needs, and persuades his wives to accompany him to a family planning clinic. Developed at a cost of approximately US $3000 and televised nationwide, the Koteba proved effective. A survey of 500 people attending an AMPPF clinic revealed that 1/4 of them remembered the program. With the success of the Koteba, JHU/PCS and AMPPF are now exploring other traditional channels of communication.

    2012-11-01

    Full Text Available Jan Fabre is one of the most controversial European scene figures. His interests range from visual arts to theater and dance. His works, disturbing and provocative, are very contemporary in style and language, while referring to the tradition of Flemish painting. With his performances Fabre demolishes traditional theatre conventions. Theatrical device questioning leads him to disorganize dynamics of representation and to elaborate the concept of crisis until death and apocalypse boundaries. In representing death, Fabre revives theater, according to the principle of metamorphosis. His entire choreography can be defined by balance seeking between opposite poles, good and evil, stasis and movement, beauty and chaos, life and death.

    Scientific publication in the electronic media is gaining popularity in academic libraries, research institutions and commercial organizations. The electronic journal may shorten the processes of writing and publication, decrease publication and distribution costs, and enable access from any location in the world. Electronic publications have unique advantages: it is possible to search them, to create hyperlinks to references and footnotes, as well as to information on the web and to include graphics and photographs at a very low cost. Audio, video and tri-dimensional images may also be included. Electronic publishing may also speed up review and publication processes and enable the writer to receive immediate feedback through the web. However, in spite of the advantages, there are certain points that must be considered: accessibility to previously published material is not guaranteed as databases are not always stable and coverage may change without notice. In addition, the price that commercial publishers charge for their services may be very high or be subject to the purchase of a packaged deal that may include unwanted databases. Many issues of copyright and the use of published material are not yet finalized. In this review we discuss the advantages and disadvantages of the electronic scientific publication, the feasibility of keeping appropriate quality and peer-review process, the stability and accessibility of databases managed by the publishers and the acceptance of the electronic format by scientists and clinicians.

    2008-02-01

    Pirate copies of feature films are proliferating on the Internet. DVD rip or screener recording methods involve the duplication of officially distributed media whereas 'cam' versions are illicitly captured with handheld camcorders in movie theaters. Several, complementary, multimedia forensic techniques such as copy identification, forensic tracking marks or sensor forensics can deter those clandestine recordings. In the case of camcorder capture in a theater, the image is often geometrically distorted, the main artifact being the trapezoidal effect, also known as 'keystoning', due to a capture viewing axis not being perpendicular to the screen. In this paper we propose to analyze the geometric distortions in a pirate copy to determine the camcorder viewing angle to the screen perpendicular and derive the approximate position of the pirate in the theater. The problem is first of all geometrically defined, by describing the general projection and capture setup, and by identifying unknown parameters and estimates. The estimation approach based on the identification of an eight-parameter homographic model of the 'keystoning' effect is then presented. A validation experiment based on ground truth collected in a real movie theater is reported, and the accuracy of the proposed method is assessed.

    2016-01-01

    To gather qualitative descriptions of music theater vocal qualities including belt, legit, and mix from expert pedagogues to better define this voice type. This is a prospective, semistructured interview. Twelve expert teachers from United States, United Kingdom, Asia, and Australia were interviewed by Skype and asked to identify characteristics of music theater vocal qualities including vocal production, physiology, esthetics, pitch range, and pedagogical techniques. Responses were compared with published studies on music theater voice. Belt and legit were generally described as distinct sounds with differing physiological and technical requirements. Teachers were concerned that belt should be taught "safely" to minimize vocal health risks. There was consensus between teachers and published research on the physiology of the glottis and vocal tract; however, teachers were not in agreement about breathing techniques. Neither were teachers in agreement about the meaning of "mix." Most participants described belt as heavily weighted, thick folds, thyroarytenoid-dominant, or chest register; however, there was no consensus on an appropriate term. Belt substyles were named and generally categorized by weightedness or tone color. Descriptions of male belt were less clear than for female belt. This survey provides an overview of expert pedagogical perspectives on the characteristics of belt, legit, and mix qualities in the music theater voice. Although teacher responses are generally in agreement with published research, there are still many controversial issues and gaps in knowledge and understanding of this vocal technique. Breathing techniques, vocal range, mix, male belt, and vocal registers require continuing investigation so that we can learn more about efficient and healthy vocal function in music theater singing.

    Directory of Open Access Journals (Sweden)

    Letícia Maria Oliveira

    2016-12-01

    Full Text Available In this work, a creative way to teach Physics to the students in Regular Education is suggested, by presenting the following aspects: how it happened, outcomes, and the way to present it to the readers. The theater was chosen, considering that scientific knowledge can be represented beyond its rigidity, at the same time that art provokes reflections in the actor and in the spectator. A group of scientific theater was created in a school in Brejo Santo, Ceará, and besides staging, a website was elaborated. The characters "Traditional Teaching" and "New Physics" are the protagonists of the story and they will show us in their dialogues, how difficult it is, however possible, to show possibilities of Physics teaching through an entertaining approach in regular schools. Among the results, positive changes were noticed in the group, as the student's posture in classroom, besides receptivity and respect among the friends and with the teacher. Besides, they began to see Physics in another way, becoming more motivated to learn this science. In that sense, considering the current brazilian education, the objective of this work focuses on the teacher's need to act in a differentiated way, through strategies and new methodologies. Therefore, the theatrical practice, more specifically, the scientific theater, can be a tool of great didactic potential in teachers’ practice, contributing for teaching process and learning of Physics.

    Electronic cigarettes (ECIGs), also referred to as electronic nicotine delivery systems (ENDS) or ‘e-cigarettes’, generally consist of a power source (usually a battery) and heating element (commonly referred to as an atomizer) that vaporizes a solution (e-liquid). The user inhales the resulting vapor. ECIGs have been increasing in popularity since they were introduced into the US market in 2007. Many questions remain about these products, and limited research has been conducted. This review will describe the available research on what ECIGs are, effects of use, survey data on awareness and use, and the utility of ECIGs to help smokers quit using tobacco cigarettes. This review will also describe arguments for and against ECIGs, and concludes with steps to move research on ECIGs forward. PMID:25089952

  1. The art in science: electron microscopy and paintings conservation

    International Nuclear Information System (INIS)

    Waters, L.

    2003-01-01

    Full text: When examining a painting, a conservator uses many different and complementary methods of analysis to build an understanding of the materials and way the painting was constructed. Common methods of examination include x-radiography, infrared reflectography, ultraviolet fluorescence and optical microscopy of the surface of the painting. Minute samples of paint prepared as cross-sections are sometimes taken for optical examination under the microscope, and it is these that can, conveniently, be further analysed with electron microscopy to yield another level of information. Electron microscopy has a valuable role to play within the examination of paintings, be it for pigment identification alone, or at the other end of the spectrum, for informing issues around the attribution of works of art. This paper provides an overview of the use of electron microscopy in the conservation of paintings by discussing examples of work undertaken by the National Gallery of Victoria and the CSIRO. Work described includes the problem of distinguishing between restorers' original paint in a landscape by Arthur Streeton, and the examination of the ground or priming layer in a Rembrandt portrait which clarified its attribution to his studio.

Except for nicotine, which can be fatal when ingested at high dose, these components are generally considered as safe. However, the potential effect of long term exposure to inhaled propylene glycol is unknown at this time. As an advantage, toxic compounds responsible for the noxiousness of tobacco smoking (nitrosamines, metals, formaldehyde, carbon monoxide …) are either absent, or present in the smoke of e-cigarette at levels far less compared to conventional cigarette smoke. Finally, efficacy of e-cigarette as a tool for smoking cessation stays to be proven.

    Protein-mediated charge transport is of relevant importance in the design of protein based electronics and in attaining an adequate level of understanding of protein functioning. This is particularly true for the case of transmembrane proteins, like those pertaining to the G protein coupled receptors (GPCRs). These proteins are involved in a broad range of biological processes like catalysis, substance transport, etc., thus being the target of a large number of clinically used drugs. This paper briefly reviews a variety of experiments devoted to investigate charge transport in proteins and present a unified theoretical model able to relate macroscopic experimental results with the conformations of the amino acids backbone of the single protein.

    Sir J. J. Thomson was the first to discover a subatomic particle i. e. electron. Due to this discovery he is remembered in the history as T he Atom Smasher . He was a great experimentalists and a devoted physicist. He himself, his son and his seven pupils earned Noble prizes on the basis of their scientific discoveries. The discovery of electron by Sir Thomson in 1897, at Cavendish Laboratory, has rewritten the entire physical science. Although electron has wide spread applications in almost every field, yet its exact nature is not fully known. This article briefly describes the life of Sir Thomson, his achievements and the impact of his discovery of electron on the twentieth century science and technology. (author)

  12. Waterpipes and electronic cigarettes: increasing prevalence and expanding science.

    2014-08-18

    The prevalence of non-cigarette tobacco product use is on the rise across the globe, especially for waterpipes (also known as hookah, narghile, and shisha) and electronic cigarettes (e-cigarettes). The scientific literature reveals that waterpipe tobacco smoking is associated with exposure to a variety of toxicants that can cause short- and long-term adverse health events. In contrast, there is far less evidence of health harms related to e-cigarette use, although the variety of products in this category makes it difficult to generalize. We searched the PubMed database for all publications on waterpipes and e-cigarettes from January 2000 to March 2014. The number of publications on waterpipes rose in a slow, linear pattern during this time, while the number of publications on e-cigarettes showed exponential growth. The different trends suggest there may be more interest in studying a novel nicotine product (the e-cigarette) over a traditional tobacco product (the waterpipe). We posit that, although the specific research needs for these products are different, public health would be served best by a more equitable research approach. Scientists should continue to devote attention to understanding the unknown long-term health effects of e-cigarettes and their potential to serve as harm reduction or smoking cessation tools while simultaneously investigating how to reduce waterpipe smoking given that it exposes users to toxicants known to cause harm to health. Recent regulatory action in the United States, which proposes to include waterpipes and e-cigarettes under some of the same regulations as tobacco cigarettes, makes such research particularly timely.

    The research and development of radiation technology in Indonesia is mainly conducted at the Center for Application of Isotopes and Radiation of the National Atomic Energy Agency (CAIR-BATAN). During the past 10 years, the center has gained a great progress in the development of gamma irradiation techniques for industrial processing, food preservation, health care products sterilization, and waste treatment. A low energy (300 keV, 50 mA) electron beam accelerator has been installed in cooperation with IAEA/UNDP as a training and demonstration facility for wood surface coating. In spite of the advantages of radiation curing, this technique is still unacceptable in the industries due to the uneconomical reasons and inferiority of the products. The research and development using this facility is also considered expensive, due to the high cost of the liquid nitrogen consumed by the accelerator. The medium energy (2 MeV, 10 mA) accelerator has been installed recently. This is a multipurpose irradiator provided with a belt conveyer, but also designed for wire and cable irradiation. The main technical parameters have been measured under different operating conditions during its commissioning, and the nominal dose measurement has been performed using alanine polyethylene, ethanol-chlorobenzene solution, and FWT-60 film dosimeters. Research and development of polymer cross-linking and shrinkable tubes have become the concern of the accelerator application. The radiation curable polyethylene compound for the cable insulation has been formulated with a characteristic of high voltage and heat resistant. Dosimetry of spices with 0.3-0.6 g/cm 3 density and health care products of 0.2-0.3 g/cm 3 density have been carried out for the promising food preservation and radiation sterilization, energy beam on micro-organism, and surface modification of some synthetic and natural polymers are also carried out.

    Full Text Available The analysis of archival sources, published memories of the corypheus (the leading actors of the Ukrainian theatre Marko Kropivnitskiy, Larisa Staryts’ka-Chernyakhivs’ka, Sofia Tobilevych, materials of the periodical press (the newspapers «Trud», «Zarya», «Kievlianin» allowed to examine the question of the first performance by the Ukrainian Professional Drama Theatre the play «Nazar Stodolya» by Taras Shevchenko in Kyiv in January 1882. The question of what preceded and caused the holding of the first performance in the Ukrainian language by the Ukrainian Professional Drama Theatre in January 1882 in Kyiv was investigated. The importance of this event for the Ukrainian society and the development of the Ukrainian Professional Drama Theatre as a whole was revealed. It is noted that in her memories L.M. Staryts’ka-Cherniakhivs’ka emphasized the value of the performance of Ukrainian Professional Drama Theater in Kyiv for the Ukrainian community. She wrote that the spectators filled the lobby and corridors, faces of all present viewers were burning from ardor and enthusiasm, their eyes were shining, there was a lively noise, the native Ukrainian language rang everywhere in the theater.  She noted that the spectators were dressed in Ukrainian national clothes, there were visible bright suits of Ukrainian women in the theater lodges, many children and parents were dressed in Ukrainian costumes in the theater lodges, there could be heard everywhere the native Ukrainian language in the theater. There was the abundance of the heart everywhere. It is found that the partial lifting of restrictions on the Ukrainian staging plays in 1881, made possible for Kyiviets to see the first performance of the Ukrainian Professional Drama Theatre in the Ukrainian language in 1882. It is found that the very first performance of the play «Nazar Stodolya» by the Ukrainian professional actors’ troupe consolidated the Ukrainian speaking Kyiviets and

  20. PROVOCATIVE PERFORMANCE, PROVOCATIVE THEATER: AESTHETIC INTERACTION

    Directory of Open Access Journals (Sweden)

    ROŞCA ANGELINA

    2017-12-01

    Full Text Available The author directs her attention to an yet-understudied area of theatre science, namely the aesthetic interaction between the provocative performance and the provocative theatre. The article sheds light on the conceptual coordinates of the performance placed among such artistic trends as Actionism, Conceptualism, Fluxus and Happening. Elements of performing arts infiltrated into the theatre long ago. And it is not just a co-occurrence within an artistic act, but an interference indeed. The provocative performance dispossesses the alternative arts of their distinct codes. First in the USA, then in Europe and eventually in the former Socialist Camp and the territory of the ex-USSR, the performance conquered the theatrical territory. This process has been accelerating since the dramatic theatre began to yield its positions to the post-dramatic one. Some of the overlapping points, which unite the performance with the spectacle in contemporary art, are followed in: the strategy of idiocy in provocative practices; the ready made; the corporeality; the pictorial.

The initial contact was made through e-mail and the questionnaire was required to be filled and returned electronically. The questionnaire was also made available online at http://sites.google.com/site/surveydelhi. After 1 month, the forms were distributed physically. Assuming that at least 50% of the approximately 1200 practising anesthesiologists would be able to recognize the greenhouse gases correctly, the target number of responses was 150 with 99% confidence limit. Of the 831 anesthesiologists contacted, only 184 responded. Ninety-eight percent were aware of the greenhouse effect, but only 15.8% (29) could correctly identify all the greenhouse gases. However, 47.28% (87) could identify nitrous oxide and inhalational agents as a cause of greenhouse effect. Ninety percent of the respondents use circle system and 87% use low flows frequently. Ninety-three percent (171) of respondents routinely use nitrous oxide, and 32.1% (59) would, however, not use air even if made available. Seventy-nine percent (145) advocated total intravenous anesthesia as an alternative to reduce the menace. Only 22% were motivated enough to respond to the survey. More than half of these anesthesiologists were not aware about the anesthetic agents contributing to the greenhouse effect. However, their clinical practices inadvertently do not add to the environmental pollution.

    Influenza is an acute respiratory infectious disease with a high incidence rate in the Chinese army, which directly disturbs military training and affects soldiers' health. Influenza surveillance systems are widely used around the world and play an important role in influenza epidemic prevention and control. As a theater centers for disease prevention and control, we established an influenza monitoring platform (IMP) in 2014 to strengthen the monitoring of influenza-like illness and influenza virus infection. In this study, we introduced the constitution, influenza virus detection, and quality control for an IMP. The monitoring effect was also evaluated by comparing the monitoring data with data from national influenza surveillance systems. The experiences and problems associated with the platform also were summarized. A theater IMP was established based on 3 levels of medical units, including monitoring sites, testing laboratories and a checking laboratory. A series of measures were taken to guarantee the quality of monitoring, such as technical training, a unified process, sufficient supervision and timely communication. The platform has run smoothly for 3 monitoring years to date. In the 2014-2015 and 2016-2017 monitoring years, sample amount coincided with that obtained from the National Influenza Surveillance program. In the 2015-2016 monitoring year, due to the strict prevention and control measures, an influenza epidemic peak was avoided in monitoring units, and the monitoring data did not coincide with that of the National Influenza Surveillance program. Several problems, including insufficient attention, unreasonable administrative intervention or subordination relationships, and the necessity of detection in monitoring sites were still observed. A theater IMP was established rationally and played a deserved role in the prevention and control of influenza. However, several problems remain to be solved.

    2006-01-01

    Full Text Available The anthropology of performance, as understood by Victor Turner, provides interesting perspectives for the analysis of what may be referred to as the "theater of bóias-frias". Conversely, this theater may be of special interest for purposes of rethinking some of the main propositions which have arisen on the borders between anthropology and performance. Considering the specificity of "the practice which calculates the place from which one views things" of this theater, several topics present themselves as guidelines for the text which follows: 1 social dramas, 2 relations between social and aesthetic dramas, 3 symbols and montage, and 4 theater paradigms in anthropology. In this exercise to rethink some of the "classic" contributions of Victor Turner, Erving Goffman, and Richard Schechner, "elective affinities" have been found between, on the one hand, the writings of Walter Benjamin and Brechtian theater, and, on the other, the dramaturgical principles of the bóias-frias.

    Researchers have envisioned an electron-ion collider with ion species up to heavy ions, high polarization of electrons and light ions, and a well-matched center-of-mass energy range as an ideal gluon microscope to explore new frontiers of nuclear science. In its most recent Long Range Plan, the Nuclear Science Advisory Committee (NSAC) of the US Department of Energy and the National Science Foundation endorsed such a collider in the form of a 'half-recommendation.' As a response to this science need, Jefferson Lab and its user community have been engaged in feasibility studies of a medium energy polarized electron-ion collider (MEIC), cost-effectively utilizing Jefferson Lab's already existing Continuous Electron Beam Accelerator Facility (CEBAF). In close collaboration, this community of nuclear physicists and accelerator scientists has rigorously explored the science case and design concept for this envisioned grand instrument of science. An electron-ion collider embodies the vision of reaching the next frontier in Quantum Chromodynamics - understanding the behavior of hadrons as complex bound states of quarks and gluons. Whereas the 12 GeV Upgrade of CEBAF will map the valence-quark components of the nucleon and nuclear wave functions in detail, an electron-ion collider will determine the largely unknown role sea quarks play and for the first time study the glue that binds all atomic nuclei. The MEIC will allow nuclear scientists to map the spin and spatial structure of quarks and gluons in nucleons, to discover the collective effects of gluons in nuclei, and to understand the emergence of hadrons from quarks and gluons. The proposed electron-ion collider at Jefferson Lab will collide a highly polarized electron beam originating from the CEBAF recirculating superconducting radiofrequency (SRF) linear accelerator (linac) with highly polarized light-ion beams or unpolarized light- to heavy-ion beams from a new ion accelerator and storage complex.

Whereas the 12 GeV Upgrade of CEBAF will map the valence-quark components of the nucleon and nuclear wave functions in detail, an electron-ion collider will determine the largely unknown role sea quarks play and for the first time study the glue that binds all atomic nuclei. The MEIC will allow nuclear scientists to map the spin and spatial structure of quarks and gluons in nucleons, to discover the collective effects of gluons in nuclei, and to understand the emergence of hadrons from quarks and gluons. The proposed electron-ion collider at Jefferson Lab will collide a highly polarized electron beam originating from the CEBAF recirculating superconducting radiofrequency (SRF) linear accelerator (linac) with highly polarized light-ion beams or unpolarized light- to heavy-ion beams from a new ion accelerator and storage complex.

    To date active research on laser-driven plasma-based accelerators have achieved great progress on production of high-energy, high-quality electron and photon beams in a compact scale. Such laser plasma accelerators have been envisaged bringing a wide range of applications in basic, medical and industrial sciences. Here inheriting the groundbreaker’s review article on “Laser Acceleration and its future” [Toshiki Tajima, (2010)],1) we would like to review recent progress of producing such electron beams due to relativistic laser-plasma interactions followed by laser wakefield acceleration and lead to the scaling formulas that are useful to design laser plasma accelerators with controllability of beam energy and charge. Lastly specific examples of such laser-driven electron/photon beam sources are illustrated. PMID:26062737

    Every professional doing active research in the life sciences is required to keep a laboratory notebook. However, while science has changed dramatically over the last centuries, laboratory notebooks have remained essentially unchanged since pre-modern science. We argue that the implementation of electronic laboratory notebooks (eLN) in academic research is overdue, and we provide researchers and their institutions with the background and practical knowledge to select and initiate the implementation of an eLN in their laboratories. In addition, we present data from surveying biomedical researchers and technicians regarding which hypothetical features and functionalities they hope to see implemented in an eLN, and which ones they regard as less important. We also present data on acceptance and satisfaction of those who have recently switched from paper laboratory notebook to an eLN.  We thus provide answers to the following questions: What does an electronic laboratory notebook afford a biomedical researcher, what does it require, and how should one go about implementing it?

    2014-10-01

    Full Text Available Improvisational theater, creative role-playing and open-ended scenarios are increasingly being used as ways to emphasize the importance of combining planning with flexibility and evolution to respond to changes in context. These skills and capabilities are extremely valuable in teaching, especially for strengthening communication and interpersonal skills, as well as the capacity for critical thinking and problem solving. Further, this combination of planning with flexibility is also a major theme of agile software development and a number of other problem-solving domains, and in the collaborative development of intellectual property in technical areas. With improvisation, the plan becomes less of a fixed framework, and more of a guideline. In software engineering, it becomes a mutable structure on which to hang goals and objectives, progress, processes, artifacts, and properties. In this submission, we explore the ramifications of this approach.

    Combat injuries are more often associated with blast, penetrating, and high-energy mechanisms than civilian trauma, generating controversy about the management of combat colonic injury. Despite implementation of mandatory colostomy in World War II, recent civilian data suggest that primary repair without diversion is safe and feasible. This study describes the modern management of battle-related colonic injuries and seeks to determine whether management strategy affects early complications. Records from the combat theater (downrange) and tertiary referral center in Germany were retrospectively reviewed from 2005 to 2006. Patient characteristics, management strategy, treatment course, and early complications were recorded. Comparison groups by management strategy were as follows: primary repair, diversion, and damage control. A total of 133 (97% male) patients sustained colonic injuries from penetrating (71%), blunt (5%), and blast (23%) mechanisms. Average injury severity score was 21 and length of stay in the referral center was 7.1 days. Injury distribution was 21% ascending, 21% descending, 15% transverse, 27% sigmoid, and 25% rectum. Downrange complications for primary repair, initial ostomy, and damage control groups were 14%, 15%, and 30%, respectively. On discharge from the center, 62% of patients had undergone a diversion. The complication rate was 18% overall and was unrelated to management strategy (P = .16). Multivariate analysis did not identify independent predictors of complications. Early complications were similar by mechanism, anatomic location, severity of injury, and management strategy. More diversions were performed for rectosigmoid injury. Good surgical judgment allows for low morbidity and supports primary repair in selected cases. Damage control surgery is effective in a multinational theater of operations.

  20. Moving social work norms via theater for senior farmers.

    Senior farmers have a 2.6-fold risk of fatal injury compared to their younger counterparts. Usual educational interventions have resulted in limited success in reducing injury. An innovative strategy, didactic readers theater, was piloted. Farmers' stories provided the foundation for the scripts. The approach incorporated adult learning strategies based on Ajzen's Theory of Planned Behavior. The intervention was marketed as a "dinner theater" to farm couples. Three short socio-novels (plays) were presented by local farmers who served as actors. Following each play participants completed a reaction form and participated in a short discussion about the play's content. One week later a phone survey was completed that tapped further reaction to the content and behavior changes. Thirty-three farm household individuals (including 16 couples) participated. Participants expressed favorable reaction to the intervention. Within one week post intervention, 42% had made safety changes and 67% were "thinking about/intending" to make changes. The use of real stories contributed to the success of this intervention. Farmers identified with the stories and began to think and talk about the impact that aging exerts on their health and safety. Interaction among the group identified work modifications which empowered the farmers to make positive changes in their own work behavior. Educational interventions with farmers have met with limited success in reducing farm-related injuries. Moreover, few interventions have utilized the family unit. This novel program, incorporating local organizations and using limited financial resources, resulted in swift behavior changes. Total Worker Health includes not only the worker, but also the family. Interventions that include family units should be considered when possible. This format is effective, easily adapted to local issues, can be delivered using existing infrastructure, and is acceptable to the farm community. It is currently being tested

    The Mars Global Surveyor (MGS) Radio Science (RS) experiment employs an ultrastable oscillator aboard the spacecraft. The signal from the oscillator to Earth is refracted by the Martian ionosphere, allowing retrieval of electron density profiles versus radius and geopotential. The present analysis is carried out on five sets of occultation measurements: (1) four obtained near northern summer solstice (Ls = 74-116, near aphelion) at high northern latitudes (64.7-77.6N), and (2) one set of profiles approaching equinox conditions (Ls = 135- 146) at high southern latitudes (64.7-69.1S). Electron density profiles (95 to 200 km) are examined over a narrow range of solar zenith angles (76.5-86.9 degrees) for local true solar times of (1) 3-4 hours and (2) 12.1 hours. Variations spanning 1-Martian year are specifically examined in the Northern hemisphere.

    Full Text Available Theatrical art had a significant influence on the formation of social and cultural space of the city at all times. Currently Khabarovsk is one of the theatrical art centres in the Russian Far East. In this regional center theaters of different genres and periods exist. To study the Khabarovsk puppet theater is relevant because of growing interest of viewers of different ages to its activity, as well as the increasing role of the theater in the cultural and social development of the Far Eastern region. The puppet theater was created and later revived in the period of social modernization of the 1920s and 1990s. The paper attempts to identify the causes of the popularization of puppet theaters in certain historical periods. The peculiarities of a puppet genre can be explained by the Russian Far East situation at that time that created the appearance of the city puppeteers in the theatrical space whose work accumulated all the best traditions of Russian and the world puppet genre. Archive documentation analysis allowed creating a holistic view of the puppet theater major directions in the period of radical transformation of the 1990s.

    Creative arts have been increasingly implemented in medical education. This study investigated the use of interactive theater and role play with professional actors in teaching breaking bad news to medical students. The objectives were to explore the contexts, approaches, experiences, and reactions in giving and receiving bad news. Second-year medical students participated in a required educational session that utilized interactive theater which helps students learn about the issues of breaking bad news to a patient with cancer. Following the interactive theater piece, professional actors provided students role play experiences in small groups with breaking bad news. Anonymous evaluation surveys were given out to all second-year medical students at the conclusion of the breaking bad news session. Surveys contained quantitative and qualitative responses. Three years of evaluations were analyzed. A total of 451 (88 %) students completed the evaluations. Comments were thematically analyzed. Ninety-four percent agreed that the theater piece prompted reflection on patient-provider communications, and 89 % agreed that it stimulated discussion on complex issues with breaking bad news. The two most common themes in student comments concerned the importance of realism in the theater piece, and the value of experiencing multiple perspectives. Use of professional actors during the role play exercises enhances the realism and pushed the students out of their own "comfort zones" in ways that may more closely approximate real life clinical situations. Interactive theater can be a potentially powerful tool to teach breaking bad news during medical school.

  9. Various Stagings of Cankar’s Works at the Slovenian National Theater in Ljubljana and Other Slovenian Theaters in the Interwar Period (1918–1941

    Full Text Available Plays by Ivan Cankar unequivocally marked Slovenian theater in the period from 1918 to 1941. In addition to Shakespeare’s works, it was Cankar’s plays that were most frequently performed on the Slovenian stage. His works especially appealed to directors that were seeking deeper, symbolic meanings of the text, which they tried to present to the audience to the best of their ability. Thus, Cankar’s narrative was intensified through directing and acting, whereas the scenery was of secondary importance in most performances. These mostly included painted scenes or backdrops to represent the setting. Only the stagings of Pohujšanje v dolini Šentflorjanski (The Scandal in the St. Florian Valley, Kralj na Betajnovi (The King of Betajnova, Hlapec Jernej in njegova pravica (The Servant Jernej and His Justice, and Lepa Vida (The Beautiful Vida contained more developed scenography. However, until the 1930s, scenery design for Cankar’s plays performed on the professional stage varied between painted backdrops and expressionist sets. It was not until the appearance of the director and scenographer Bojan Stupica that the scenery of these plays reached the boundaries of new realism and modern avant-garde. Until then, an unspoken rule had been in force that the scenery of Cankar’s plays should not extend beyond the boundaries of expressionism. This rule was observed even by the avant-garde painter Avgust Černigoj. However, Cankar’s plays were staged completely differently in workers’ theaters and popular theaters. With new avant-garde staging, they often surpassed the development of theater design in professional theaters, and caught up with contemporary formal ideas in Slovenian and European fine arts. Here, Cankar’s works were staged as anti-political propaganda. In order to better express their new ideas, these theaters also used new tools, such as projectors and film clips, and experimented with spotlights. The most original among these

    Metamaterials, which enable us to realize novel physical effects that cannot be achieved using natural materials, have been extensively studied in recent years and significant progress has been made, especially in the field of optics. This game-changing concept has also initiated a rich variety of research activity in vacuum electronics. Here we review the recent development of metamaterial-based vacuum electronics for terahertz (THz) and microwave science and technology. The reversed Cherenkov radiation (RCR) in double-negative (DNG) metamaterials predicted by Veselago back in the 1960s has been experimentally verified in the microwave frequency range by utilizing specially designed DNG metamaterials. The interaction of an electron beam (e-beam) with DNG metamaterials may lead to the realization of novel applications such as microwave and THz radiation sources, accelerators, and even the visualization of invisibility cloaks. Smith-Purcell radiation (SPR) has recently received renewed interest owing to the development of metamaterials and the concept of spoof surface plasmon polaritons, as discussed in this review, and recent results on e-beam-induced directional and wide-band THz radiation with sharp multiple peaks from a graded grating, as well as directional and monochromatic special SPR and their possible application to THz orotron devices, are also reviewed.

    Electronic laboratory notebooks (ELNs) offer significant advantages over traditional paper laboratory notebooks (PLNs), yet most research labs today continue to use paper documentation. While biopharmaceutical companies represent the largest portion of ELN users, government and academic labs trail far behind in their usage. Our lab, a translational science laboratory at New York University School of Medicine (NYUSoM), wanted to determine if an ELN could effectively replace PLNs in an academic research setting. Over 6 months, we used the program Evernote to record all routine experimental information. We also surveyed students working in research laboratories at NYUSoM on the relative advantages and limitations of ELNs and PLNs and discovered that electronic and paper notebook users alike reported the inability to freehand into a notebook as a limitation when using electronic methods. Using Evernote, we found that the numerous advantages of ELNs greatly outweighed the inability to freehand directly into a notebook. We also used imported snapshots and drawing program add-ons to obviate the need for freehanding. Thus, we found that using Evernote as an ELN not only effectively replaces PLNs in an academic research setting but also provides users with a wealth of other advantages over traditional paper notebooks.

    This book is about change: in the Soviet Union, in Eastern Europe, and how we in the West should respond. Few observers of the international scene, even in their wildest dreams, could have imagined the course of events that have taken place in Europe since early 1989. The communist system came to a dead end. Old social, economic, political, and psychological recipes no longer were acceptable, either in the Soviet Union or in Eastern Europe. Soviet leadership had only two choices: repress change in Eastern Europe and demand continued sacrifices from its own people, or press forward on the road of economic reform and political restructuring at home and the pursuit of new relationships abroad. The three volumes on Alternative Conventional Defense Postures in the European Theater contributed significantly to the current debate in Europe and in the United States on the future of European security. As an outgrowth of a German-American workshop at the Army War College in Carlisle, Pennsylvania, the two editors have succeeded in bringing together statesmen, soldiers, and civilian defense specialist from the Federal Republic, the United States, and the Soviet Union, who represent a variety of schools of political and strategic thinking

    2016-01-01

    This study aims to explore the views of members of theater teams regarding the proposed introduction of a workplace-based assessment of nontechnical skills of surgeons (NOTSS) into the Intercollegiate Surgical Curriculum Programme in the United Kingdom. In addition, the previous training and familiarity of the members of the surgical theater team with the concept and assessment of NOTSS would be evaluated. A regional survey of members of theater teams (consultant surgeons, anesthetists, scrub nurses, and trainees) was performed at 1 teaching and 2 district general hospitals in South Yorkshire. There were 160 respondents corresponding to a response rate of 81%. The majority (77%) were not aware of the NOTSS assessment tool with only 9% of respondents reporting to have previously used the NOTSS tool and just 3% having received training in NOTSS assessment. Overall, 81% stated that assessing NOTSS was as important as assessing technical skills. Trainees attributed less importance to nontechnical skills than the other groups (p ≤ 0.016). Although opinion appears divided as to whether the presence of a consultant surgeon in theater could potentially make it difficult to assess a trainee's leadership skills and decision-making capabilities, overall 60% agree that the routine use of NOTSS assessment would enhance safety in the operating theater and 80% agree that the NOTSS tool should be introduced to assess the nontechnical skills of trainees in theater. However, a significantly lower proportion of trainees (45%) agreed on the latter compared with the other groups (p = 0.001). Our survey demonstrates acceptability among the theater team for the introduction of the NOTSS tool into the surgical curriculum. However, lack of familiarity highlights the importance of faculty training for assessors before such an introduction. Copyright © 2015 Association of Program Directors in Surgery.

    Full Text Available The article examines “theater” as a cultural and artistic universal that served as a means ofThe article examines “theater” as a cultural and artistic universal that served as a means of developing mindset and self-identity of the Austrian literary group “Young Vienna” at the thth turn of the 19 and 20 centuries. Theater as a metaphor of the human life becomes integral part of the poetics in the works of the group members. The essay examines ideas and fictional worlds of the writers belonging to the group against the context of their contemporary culture. It touches upon Russian perception of the aesthetics of Viennese theater (A. Block, A.J. Tairov and involves retrospective evidences and reflections of Austrian authors (Stefan thth weig, G. Broch on Vienna at the turn of the 19 and 20centuries. As soon as Habsburgs’ empire loses its political positions, the theatrical illusion becomes more and more important. Yet it is the “Young Vienna” that makes the idea of the theater all-pervading: this concept includes both the motif of hopeless masquerade (Schnitzler and the motif of liberation from the false play of masks (Hofmannsthal. According to the concept of the group’s mastermind H. Bahr, the theater played essential role in the spiritual and aesthetic integration of Austria. References to the mystery genre, the street theater, the puppet theater may be traced in the plays written by the members of the group. Austrian authors reconstructed folk plays that enabled the mactualize primordial theatrical forms and inspired them to subtly play with these forms. For the “Young Vienna” group, theater becomes a projection of doubts and misgivings of their time. In place of a jaded actor, there comes a person without a mask who appears at once unprotected and open to acquire his or her “true” face.

    This report summarizes a 2011 workshop that addressed the potential role of rapid, time-resolved electron microscopy measurements in accelerating the solution of important scientific and technical problems. A series of U.S. Department of Energy (DOE) and National Academy of Science workshops have highlighted the critical role advanced research tools play in addressing scientific challenges relevant to biology, sustainable energy, and technologies that will fuel economic development without degrading our environment. Among the specific capability needs for advancing science and technology are tools that extract more detailed information in realistic environments (in situ or operando) at extreme conditions (pressure and temperature) and as a function of time (dynamic and time-dependent). One of the DOE workshops, Future Science Needs and Opportunities for Electron Scattering: Next Generation Instrumentation and Beyond, specifically addressed the importance of electron-based characterization methods for a wide range of energy-relevant Grand Scientific Challenges. Boosted by the electron optical advancement in the last decade, a diversity of in situ capabilities already is available in many laboratories. The obvious remaining major capability gap in electron microscopy is in the ability to make these direct in situ observations over a broad spectrum of fast (µs) to ultrafast (picosecond [ps] and faster) temporal regimes. In an effort to address current capability gaps, EMSL, the Environmental Molecular Sciences Laboratory, organized an Ultrafast Electron Microscopy Workshop, held June 14-15, 2011, with the primary goal to identify the scientific needs that could be met by creating a facility capable of a strongly improved time resolution with integrated in situ capabilities. The workshop brought together more than 40 leading scientists involved in applying and/or advancing electron microscopy to address important scientific problems of relevance to DOE’s research

The data were obtained by questionnaires sent to (1) the 61 recognized Airway Science Institutions, (2) personal interviews with department chairmen who are members of the Oklahoma City Aviation Aerospace Alliance and (3) personal interviews were also conducted with Electronics Technicians and supervisors at the Mike Monroney Aeronautical Center, Oklahoma City, Oklahoma. It was found that the present area of airway science curriculum encompasses Airway Science Management, Airway Computer Science, Airway Electronics Systems, Aviation Maintenance Management and Aircraft Systems Management. Programs in airway science are designed specifically to help prepare individuals for meeting the requirements for a strong educational background for tomorrow's aviation leaders. The data indicated that the majority of airway science students pursue careers with the FAA but also find even greater opportunities in industry. The data also shows that in the surveyed schools with approved airway science programs, Airway Science Management was the most frequent offered program.

    important role of ET is combined with the existence in the society of an adequate infrastructure which recreates the full development cycle of high technology embracing: people, institutions, finances and logistics, in this also science, higher education, education, continuous training, dissemination and outreach, professional social environment, legal basis, political support and lobbying, innovation structures, applications, industry and economy. The digest of chosen development tendencies in ET was made here from the academic perspective, in a wider scale and on this background the national one, trying to situate this branch in the society, determine its changing role to build a new technical infrastructure of a society based on knowledge, a role of builder of many practical gadgets facilitating life, a role of a big future integrator of today's single bricks into certain more useful unity. This digest does not have a character of a systematic analysis of ET. It is a kind of an arbitrary utterance of the authors inside their field of competence. The aim of this paper is to take an active part in the discussion of the academic community in this country on the development strategy of ET, choice of priorities for cyclically rebuilding economy, in competitive environments. The review paper was initiated by the Committee of Electronics and Telecommunications of Polish Academy of Sciences and was published in Polish as introductory chapter of a dedicated expertise, printed in a book format. This version makes the included opinions available for a wider community.

    Obtaining the eigenvalues and eigenvectors of large matrices is a key problem in electronic structure theory and many other areas of computational science. The computational effort formally scales as O(N(3)) with the size of the investigated problem, N (e.g. the electron count in electronic structure theory), and thus often defines the system size limit that practical calculations cannot overcome. In many cases, more than just a small fraction of the possible eigenvalue/eigenvector pairs is needed, so that iterative solution strategies that focus only on a few eigenvalues become ineffective. Likewise, it is not always desirable or practical to circumvent the eigenvalue solution entirely. We here review some current developments regarding dense eigenvalue solvers and then focus on the Eigenvalue soLvers for Petascale Applications (ELPA) library, which facilitates the efficient algebraic solution of symmetric and Hermitian eigenvalue problems for dense matrices that have real-valued and complex-valued matrix entries, respectively, on parallel computer platforms. ELPA addresses standard as well as generalized eigenvalue problems, relying on the well documented matrix layout of the Scalable Linear Algebra PACKage (ScaLAPACK) library but replacing all actual parallel solution steps with subroutines of its own. For these steps, ELPA significantly outperforms the corresponding ScaLAPACK routines and proprietary libraries that implement the ScaLAPACK interface (e.g. Intel's MKL). The most time-critical step is the reduction of the matrix to tridiagonal form and the corresponding backtransformation of the eigenvectors. ELPA offers both a one-step tridiagonalization (successive Householder transformations) and a two-step transformation that is more efficient especially towards larger matrices and larger numbers of CPU cores. ELPA is based on the MPI standard, with an early hybrid MPI-OpenMPI implementation available as well. Scalability beyond 10,000 CPU cores for problem

  20. Theater and the Discourse on Power: Jose Rizal’s Participation in Philippine Theater in the Last Decades of the Nineteenth Century

    2007-06-01

    Full Text Available The study focuses on Jose Rizal’s participation in Philippine Theater during the last decades of the nineteenth century. It starts with a careful inventory of attitudes towards existing theater forms and a description of the culture of theater as conceived and imagined in Rizal’s Noli Me Tangere (1887 and El Filibusterismo (1891. In Chapter 20: “The Town Council’s Meeting” in Noli Me Tangere, the study zooms in on the debate on what would be the best and most appropriate theatre piece for the town fiesta. Here, Rizal delineates theater enmeshed in issues of power and Spanish colonialism. He notes as significant the ilustrados’ claim to theatre space and ideology, thereby interrogating Spanish hegemony. The debate becomes the central imagery and situation for Rizal’s analysis and construction of the history of Philippine theater in the novel. Conservative and radical elements duel. The conflict becomes sharper as Rizal continues his critique by putting into his fictional world the very historical actors known at that time; namely, Nemesio Ratia, Jose Carvajal and Praxedes Julia Fernandez (also known as “Yeyeng”. They were part of the comedia troupe hired by the town for the fiesta. In Rizal’s second novel, El Filibusterismo, we encounter the events surrounding the presentation by a French opera troupe in Teatro de Variedades, which Rizal considers as the Manila theater model. The features of this model include a particular ticket system, various kinds of audiences, imported dramatic texts which were largely incomprehensible, actors behaving as actors both on-stage and off-stage, and the Teatro de Variedades space as stage for seizure or possession of power. When the students in the audience stage a walk-out in the theatre of the city and when in provincial San Diego, a stampede cuts short a comedia performance, the interrelationships between society and a discourse of power are revealed.Rizal’s annotations of Philippine

    The Radiation Assessment Detector (RAD), on board the Mars Science Laboratory (MSL) rover Curiosity, measures the energetic charged and neutral particles and the radiation dose rate on the surface of Mars. Although charged and neutral particle spectra have been investigated in detail, the electron and positron spectra have not been investigated yet. The reason for that is that they are difficult to separate from each other and because of the technical challenges involved in extracting energy spectra from the raw data. We use GEANT4 to model the behavior of the RAD instrument for electron/positron measurements.We compare Planetocosmics predictions for different atmospheric pressures and different modulation parameters Φ with the obtained RAD electron/positron measurements.We find that the RAD electron/positron measurements agree well with the spectra predicted by Planetocosmics. Both RAD measurements and Planetocosmics simulation show a dependence of the electron/positron fluxes on both atmospheric pressure and solar modulation potential.

    Full Text Available Current theaters of operations are not limited to battlefields, but they are much morediversified, including the fight against the international terrorism phenomenon, the social conflicts (ofreligious, political, economic and separatist nature within several countries, thus supplying somepolitical-military conflicts within different states and areas of the world. The armed interference mustbe done based on some highly accurate information that must be gathered without endangering thehuman lives. This is the role currently played by the unmanned air vehicles (UAVs; they can performseveral functions: surveillance, information gathering, data storage and their transmission to theground stations, including the function of interference, when needed. This paper presents, within theabove context, the status of the current theaters of operations and of the UAVs performing differentmissions within these theaters, together with their role and importance in warfare operations.

    2014-09-01

    Singing styles in Musical Theater singing might differ in many ways from Western Classical singing. However, vocal tract adjustments are not understood in detail. Vocal tract shapes of a single professional Music Theater female subject were analyzed concerning different aspects of singing styles using dynamic real-time magnetic resonance imaging technology with a frame rate of 8 fps. The different tasks include register differences, belting, and vibrato strategies. Articulatory differences were found between head register, modal register, and belting. Also, some vibrato strategies ("jazzy" vibrato) do involve vocal tract adjustments, whereas others (classical vibrato) do not. Vocal tract shaping might contribute to the establishment of different singing functions in Musical Theater singing. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc.

  8. Street Theater and Subject Formation in Wartime China: Toward a New Form of Public Art

    Directory of Open Access Journals (Sweden)

    Xiaobing Tang

    2016-03-01

    Full Text Available Based on archival research, this article presents a succinct history of the street theater movement in China through the 1930s. It examines how complex discourses and competing visions, as well as historical events and practices—in particular the War of Resistance against Japan—both shaped and propelled the movement. The author focuses on theoretical and practical issues that promoters and practitioners of street theater dealt with and reflected on in three succeeding stages. Observing that the street theater movement hastened the formation of a modern national imagination, the author argues that the movement presented a paradigmatic development as it foregrounded the imperative to engage rural China as well as the need for participants to acquire new subject positions.

  9. MGS Radio Science Electron Density Profiles: Interannual Variability and Implications for the Martian Neutral Atmosphere

    Martian electron density profiles provided by the Mars Global Surveyor (MGS) Radio Science (RS) experiment over the 95-200 km altitude range indicate what the height of the electron peak and the longitudinal structure of the peak height are sensitive indicators of the physical state of the Mars lower and upper atmospheres. The present analysis is carried out on five sets of occultation profiles, all at high solar zenith angles (SZA). Variations spanning 2 Martian years are investigated near aphelion conditions at high northern latitudes (64.7 - 77.6 N) making use of four of these data sets. A mean ionospheric peak height of 133.5 - 135 km is obtained near SZA = 78 - 82 deg.; a corresponding mean peak density of 7.3 - 8.5 x l0(exp 4)/ qu cm is also measured during solar moderate conditions at Mars. Strong wave number 2 - 3 oscillations in peak heights are consistently observed as a function of longitude over the 2 Martian years. These observed ionospheric features are remarkably similar during aphelion conditions 1 Martian year apart. This year-to-year repeatability in the thermosphere-ionosphere structure is consistent with that observed in multiyear aphelion temperature data of the Mars lower atmosphere. Coupled Mars general circulation model (MGCM) and Mars thermospheric general circulation model (MTGCM) codes are run for Mars aphelion conditions, yielding mean and longitude variable ionospheric peak heights that reasonably match RS observations. A tidal decomposition of MTGCM thermospheric densities shows that observed ionospheric wave number 3 features are linked to a non-migrating tidal mode with semidiurnal period (sigma = 2) and zonal wave number 1 (s = -1) characteristics. The height of this photochemically determined ionospheric peak should be monitored regularly.

  10. Segmenting the Performing Arts Markets: The Case of Czech National Theater Attenders’ Motivations

    2012-09-01

    Full Text Available Strategic marketing instruments such as segmentation and targeting can benefit performing arts institutions and render their offer more competitive. To segment classical performing arts audiences, however, the traditionally used variable is social class. In this paper, it is argued that such often suggested traditional segmentation criteria can prove to be context-insensitive and as such cannot be applied invariably across different settings. Based on an analysis of Czech National Theater audiences and its motivations, we propose the sought benefit of the theater visit as an alternative segmentation basis that may prove to be more context-sensitive.

    The capabilities of modern semiconductor manufacturing offer remarkable possibilities to be applied in life science research as well as for its commercialization. In this review, the technology modules available in micro- and nano-electronics are exemplarily presented for the case of 250 and 130 nm technology nodes. Preparation procedures and the different transistor types as available in complementary metal-oxide-silicon devices (CMOS) and BipolarCMOS (BiCMOS) technologies are introduced as key elements of comprehensive chip architectures. Techniques for circuit design and the elements of completely integrated bioelectronics systems are outlined. The possibility for life scientists to make use of these technology modules for their research and development projects via so-called multi-project wafer services is emphasized. Various examples from diverse fields such as (1) immobilization of biomolecules and cells on semiconductor surfaces, (2) biosensors operating by different principles such as affinity viscosimetry, impedance spectroscopy, and dielectrophoresis, (3) complete systems for human body implants and monitors for bioreactors, and (4) the combination of microelectronics with microfluidics either by chip-in-polymer integration as well as Si-based microfluidics are demonstrated from joint developments with partners from biotechnology and medicine.

    The primary goals of this project were to: 1. Promote and enhance K-12 earth science education; and enhance the access to and exchange of information through the use of digital networks in K-12 institutions. We have achieved these two goals. Through the efforts of many individuals at the University of Nebraska-Lincoln (UNL), Nebraska Earth Science Education Network (NESEN) has become a viable and beneficial interdisciplinary outreach program for K-12 educators in Nebraska. Over the last three years, the NASA grant has provided personnel and equipment to maintain, expand and develop NESEN into a program that is recognized by its membership as a valuable source of information and expertise in earth systems science. Because NASA funding provided a framework upon which to build, other external sources of funding have become available to support NESEN programs.

    Science.gov (United States)

    1995-05-05

    New York City's decision to close a gay movie theater where inspectors found male patrons engaging in unsafe sexual activity with other men was upheld by Justice Marilyn G. Diamond of the Supreme Court in Manhattan. She rejected the theater owner's argument that the city's March 31, 1995 closure of the New David Cinema on West 54th Street violated the Constitution's guarantee of freedom of speech. The city based its action on a provision in the state health code which prohibits oral, anal or vaginal sex in commercial establishments. Despite several warnings from the city, the movie house did not follow the demands that it move forcefully to prevent high-risk sexual activity among patrons. The New David was one of two theaters and one sex club shut down by the Health Department in recent weeks, but the only one still closed at press time. Some gay activists contend the action was unjustified, since most of the sex that occurs in those establishments in consensual and involves solo or mutual masturbation. Others point out that a good deal of unsafe sex does occur. Because men often have several sexual liaisons during a single night at a theater or club, the risk of HIV transmission is magnified many-fold.

    2018-01-01

    Diabetes treatment involves a demanding self-management regime that is particularly challenging to adolescents. There is a need for qualitative research into the specific contexts in which adolescents attempt to balance self-management demands with the needs and desires of adolescent life. This study investigates the usefulness of image theater, a participatory form of theater using the body as an expressive tool, to articulate these dilemmas in daily life contexts. We performed a qualitative analysis of two image theater workshops with 12- to 18-year-old adolescents living with diabetes. Our results show three areas of application: (a) unraveling the contextual complexity of lived experience, (b) the articulation of implicit understandings and underlying motives, and (c) the playful exploration of new behavior. We conclude that image theater is a promising method, especially with respect to the opportunities of a more contextual and action-oriented understanding of the trade-offs made in self-management provide for diabetes education and counseling.

  9. Net current measurements and secondary electron emission characteristics of the Voyager plasma science experiment and their impact on data interpretation

    Science.gov (United States)

    Mcnutt, Ralph L., Jr.

    1988-01-01

    The Voyager Plasma Science (PLS) instrument is capable of returning integral (DC) current measurements, similar in some respects to measurements made with a Langmuir probe or a retarding potential analyzer, although there are significant differences. The integral measurements were made during a calibration sequence in the solar wind, during Cruise Science Maneuvers, and within the magnetospheres of Jupiter and Saturn by Voyager 1. After the failure of the PLS experiment following the Saturn encounter, that instrument was placed in the DC return mode returning possibly usable data from early 1981 through early 1985. The DC return measurements are difficult to interpret and are above threshold values only for relatively large fluxes; the determination of the measured current level is dependent on the operating temperature of the preamplifiers which further complicates the interpretation. Nevertheless, these measurements can be used to determine the efficiency of the suppressor grid at preventing the loss of secondary electrons off the collector plate. Some DC return measurements have been invaluable in aiding in the interpretation of some electron plasma measurements not previously understood. It is found that electron spectra can be significantly modified by the presence of second generation secondary electrons produced by either first generation secondaries or photoelectrons on the support ring of the negative high voltage modulator grid within the instrument housing.

    Environmental transmission electron microscopy and ultra-high resolution electron microscopic observation using aberration correctors have recently emerged as topics of great interest. The former method is an extension of the so-called in situ electron microscopy that has been performed since the 1970s. Current research in this area has been focusing on dynamic observation with atomic resolution under gaseous atmospheres and in liquids. Since 2007, Nagoya University has been developing a new 1-MV high voltage (scanning) transmission electron microscope that can be used to observe nanomaterials under conditions that include the presence of gases, liquids and illuminating lights, and it can be also used to perform mechanical operations to nanometre-sized areas as well as electron tomography and elemental analysis by electron energy loss spectroscopy. The new instrument has been used to image and analyse various types of samples including biological ones.

    Full Text Available The Radiation Assessment Detector (RAD, on board the Mars Science Laboratory (MSL rover Curiosity, measures the energetic charged and neutral particles and the radiation dose rate on the surface of Mars. Although charged and neutral particle spectra have been investigated in detail, the electron and positron spectra have not been investigated yet. The reason for that is that they are difficult to separate from each other and because of the technical challenges involved in extracting energy spectra from the raw data. We use GEANT4 to model the behavior of the RAD instrument for electron/positron measurements. We compare Planetocosmics predictions for different atmospheric pressures and different modulation parameters Φ with the obtained RAD electron/positron measurements. We find that the RAD electron/positron measurements agree well with the spectra predicted by Planetocosmics. Both RAD measurements and Planetocosmics simulation show a dependence of the electron/positron fluxes on both atmospheric pressure and solar modulation potential.

    Advances and applications of electron holography to the study of electromagnetic fields in various functional materials are presented. In particular, the development of split-illumination electron holography, which introduces a biprism in the illumination system of a holography electron microscope, enables highly accurate observations of electromagnetic fields and the expansion of the observable area. First, the charge distributions on insulating materials were studied by using split-illumination electron holography and including a mask in the illumination system. Second, the three-dimensional spin configurations of skyrmion lattices in a helimagnet were visualized by using a high-voltage holography electron microscope. Third, the pinning of the magnetic flux lines in a high-temperature superconductor YBa 2 Cu 3 O 7-y was analyzed by combining electron holography and scanning ion microscopy. Finally, the dynamic accumulation and collective motions of electrons around insulating biomaterial surfaces were observed by utilizing the amplitude reconstruction processes of electron holography. © 2016 WILEY-VCH Verlag GmbH & Co.

    2016-01-01

    Full Text Available Every professional doing active research in the life sciences is required to keep a laboratory notebook. However, while science has changed dramatically over the last centuries, laboratory notebooks have remained essentially unchanged since pre-modern science. We argue that the implementation of electronic laboratory notebooks (eLN in academic research is overdue, and we provide researchers and their institutions with the background and practical knowledge to select and initiate the implementation of an eLN in their laboratories. In addition, we present data from surveying biomedical researchers and technicians regarding which hypothetical features and functionalities they hope to see implemented in an eLN, and which ones they regard as less important. We also present data on acceptance and satisfaction of those who have recently switched from paper laboratory notebook to an eLN.  We thus provide answers to the following questions: What does an electronic laboratory notebook afford a biomedical researcher, what does it require, and how should one go about implementing it?

    Full Text Available The article deals with the issues of artwork impact on ballet artists’ and ballet masters’ creativity – creation of choreographic works based on artworks. Facts (examples demonstrating such borrowing are involved, but more significantly, the range of potential opportunities, which may enrich modern ballet theater, is outlined. The matter of figurative material takes on particular importance, i.e. the issue to what extent a choreographic work reflects the essence of an artwork accurately, deeply, and adequately. The article considers the connection and mutual benefit of the processes of creative interpenetration of graphics, art, sculpture, arts and crafts, and ballet theater. Different techniques of figurative sources are studied: illustration, statement, demonstration, comparison, event localization, generalization, stylistic device, and their visualization by means of choreographic dynamics. It’s concluded the synthetic nature of ballet theatergives rise to new polygenre structures that can intensify both expressive and semantic content of choreographic image, create original stage solutions.

  1. Participatory Theater, Is It Really? A Critical Examination of Practices in Timor-Leste

    2013-01-01

    Full Text Available Dance, music, and oral narratives are an important and vibrant part of cultural practice and heritage in Timor-Leste. But while Timorese people have used such creative methods and processes during rituals, celebrations, and their fight for independence, today arts and artistic expression become an increasingly popular strategy in development cooperation. Especially diff erent forms of so-called participatory theater with origins in development cooperation, arts, and social movements, present themselves as innovative, participatory, and well applicable in terms of capacity building and stimulating positive social transformation. Based on the author’s experience and observations, this article critically examines the alliance between various stakeholders in Timor-Leste engaging with the fact that the current scene of participatory theater can hardly be seen as an independent grassroots or even social movement, rather than an initiated top-down process by donors with specific agendas.

    2013-08-01

    INtraoperative Video Enhanced Surgical procedure Training (INVEST) is a new training method designed to improve the transition from basic skills training in a skills lab to procedural training in the operating theater. Traditionally, the master-apprentice model (MAM) is used for procedural training in the operating theater, but this model lacks uniformity and efficiency at the beginning of the learning curve. This study was designed to investigate the effectiveness and efficiency of INVEST compared to MAM. Ten surgical residents with no laparoscopic experience were recruited for a laparoscopic cholecystectomy training curriculum either by the MAM or with INVEST. After a uniform course in basic laparoscopic skills, each trainee performed six cholecystectomies that were digitally recorded. For 14 steps of the procedure, an observer who was blinded for the type of training determined whether the step was performed entirely by the trainee (2 points), partially by the trainee (1 point), or by the supervisor (0 points). Time measurements revealed the total procedure time and the amount of effective procedure time during which the trainee acted as the operating surgeon. Results were compared between both groups. Trainees in the INVEST group were awarded statistically significant more points (115.8 vs. 70.2; p < 0.001) and performed more steps without the interference of the supervisor (46.6 vs. 18.8; p < 0.001). Total procedure time was not lengthened by INVEST, and the part performed by trainees was significantly larger (69.9 vs. 54.1 %; p = 0.004). INVEST enhances effectiveness and training efficiency for procedural training inside the operating theater without compromising operating theater time efficiency.

    A 28 GHz electron cyclotron resonance (ECR) ion source is being developed for use as an injector for the superconducting linear accelerator of the Rare Isotope Science Project. Beam extraction from the ECR ion source has been simulated using the KOBRA3-INP software. The simulation software can calculate charged particle trajectories in three dimensional complex magnetic field structures, which in this case are formed by the arrangement of five superconducting magnets. In this study, the beam emittance is simulated to understand the effects of plasma potential, mass-to-charge ratio, and spatial distribution. The results of these simulations and their comparison to experimental results are presented in this paper.

    Since 2001, U.S. military personnel and active duty, uniformed physicians providing medical support have been deployed to Afghanistan. Medical toxicologists are among the physicians deployed. There is a paucity of information present in the literature that has documented cases treated by toxicologists in theater. This prospective observational study describes 15 male patients treated in theater by a military medical toxicologist. We performed a prospective observational study in which a medical toxicologist consulted and reported on deployed toxicology cases occurring during a 5-month deployment to Bagram, Afghanistan. Fifteen toxicology cases were collected during the 5-month period. The patients included three Afghan civilians, three U.S. civilians, and nine U.S. military personnel. Eight cases were attempts at recreational euphoria, two were self-harm attempts, two were from performance-enhancing supplements, two were accidental occupational exposures and one was alcohol withdrawal. Methanol was the most common exposure followed by dextromethorphan, supplements, opiates, and chlorine gas. In our study, we found that toxic alcohols and nonprescription medications were the most common exposures. In addition, this is the first study to describe bedside toxicology consults for U.S. combat forces in theater and the use of an observation unit for critically ill patients.

    2018-02-01

    The importance of maintaining performance of a hospital operating theater is to establish an adequate circulation of clean air within the room. The parameter of air distribution in a space should be based on Air Changes per Hour (ACH) to maintain a positive room pressure. The dispersion of airborne particles in the operating theater was governed by regulating the air distribution so that the operating theater meets clean room standards ie ISO 14664 and ASHRAE 170. Here, we introduced several input parameters in a simulation environment to observe the pressure distribution in the room. Input parameters were air temperature, air velocity and volumetric flow rate entering and leaving room for existing and designed condition. In the existing operating theatre, several observations were found. It was found that the outlet air velocity at the HEPA filter above the operating table was too high thus causing a turbulent airflow pattern. Moreover, the setting temperature at 19°C was found to be too low. The supply of air into the room was observed at lower than 20 ACH which is under the standard requirement. Our simulation using FloVent 8.2™ program showed that not only airflow turbulence could be reduced but also the amount of particle contamination could also be minimized.

    2012-03-01

    Along with the success of the digitally revived stereoscopic cinema, events beyond 3D movies become attractive for movie theater operators, i.e. interactive 3D games. In this paper, we present a case that explores possible challenges and solutions for interactive 3D games to be played by a movie theater audience. We analyze the setting and showcase current issues related to lighting and interaction. Our second focus is to provide gameplay mechanics that make special use of stereoscopy, especially depth-based game design. Based on these results, we present YouDash3D, a game prototype that explores public stereoscopic gameplay in a reduced kiosk setup. It features live 3D HD video stream of a professional stereo camera rig rendered in a real-time game scene. We use the effect to place the stereoscopic effigies of players into the digital game. The game showcases how stereoscopic vision can provide for a novel depth-based game mechanic. Projected trigger zones and distributed clusters of the audience video allow for easy adaptation to larger audiences and 3D movie theater gaming.

    Full Text Available Youth is one of the challenging issues to social development policies in Latin America. When socially vulnerable, this age group is at risk of losing future prospects in case minimum conditions are not ensured for active participation in the process of gaining citizenship. In this sense, it is important to develop actions to enable a reduction of the vulnerability process impacts in their daily lives. In this study, we aimed to describe and analyze the use of drama as a therapeutic resource with young people in occupational social vulnerability in the process of awareness and youth participation. To this end, we carried out a case study with qualitative approach in a philanthropic institution in the state of Minas Gerais. Ten meetings were conducted using drama the activities proposed by Augusto Boal, a theatrical presentation to the community using the technique of the theater-forum and focus groups. Data collection occurred through filming and the production of journals analyzed by Content Analysis. We developed three thematic categories: drama as an instrument of expression of the vulnerability conditions of young people; drama and social microcosm of the group and the family; and Theatre Forum and the development of coping strategies. Throughout the process, the technique of the theater of the oppressed enabled the critical thinking development of young people regarding the problems experienced, which helped to promote a dialogue with the community and the family. The community realized the social role of theater, reflecting on the problems experienced by youth.

  18. 3D imaging by serial block face scanning electron microscopy for materials science using ultramicrotomy.

    Science.gov (United States)

    Hashimoto, Teruo; Thompson, George E; Zhou, Xiaorong; Withers, Philip J

    2016-04-01

    Mechanical serial block face scanning electron microscopy (SBFSEM) has emerged as a means of obtaining three dimensional (3D) electron images over volumes much larger than possible by focused ion beam (FIB) serial sectioning and at higher spatial resolution than achievable with conventional X-ray computed tomography (CT). Such high resolution 3D electron images can be employed for precisely determining the shape, volume fraction, distribution and connectivity of important microstructural features. While soft (fixed or frozen) biological samples are particularly well suited for nanoscale sectioning using an ultramicrotome, the technique can also produce excellent 3D images at electron microscope resolution in a time and resource-efficient manner for engineering materials. Currently, a lack of appreciation of the capabilities of ultramicrotomy and the operational challenges associated with minimising artefacts for different materials is limiting its wider application to engineering materials. Consequently, this paper outlines the current state of the art for SBFSEM examining in detail how damage is introduced during slicing and highlighting strategies for minimising such damage. A particular focus of the study is the acquisition of 3D images for a variety of metallic and coated systems. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

    Full Text Available The study determined the employment status of the graduates of BS Electronics Engineering from 1999 to 2011. It also addressed the relevance of the ECE program outcomes and school factors to their employability. Pertinent data were gathered using a questionnaire and the sample size of 180 was determined using Slovin’s formula. Findings revealed that the graduates are highly employable in a wide range of industry such as electronics manufacturing, electronics design, telecommunications, broadcasting, and data communications and ICT-related areas, were able to pass the licensure examinations and other certifications, currently enjoying regular permanent job positions as supervisors, production engineers, process engineers, educators and others, and are working for companies located in Metro Manila and industrial zones in Laguna and Cavite. A significant number work abroad as OFWs. Only a small number are employed in the province of Camarines Sur mainly due to the lack of electronics industries and employment opportunities in the area. The skills the graduates found most useful to their first jobs are critical thinking, problem solving, and communication skills. Suggestions were given such as the inclusion of industry-utilized software and enhancement of the OJT program, more hands-on activities in the curriculum, exposure to industry while studying, and job familiarization among others. The findings of the study can serve as basis for curriculum review and revision to meet the demands of the industry.

    2012-06-01

    Full Text Available Degradation of the photocathode materials employed in photoinjectors represents a challenge for sustained operation of nuclear physics accelerators and high power free electron lasers (FEL. Photocathode quantum efficiency degradation is due to residual gases in the electron source vacuum system being ionized and accelerated back to the photocathode. These investigations are a first attempt to characterize the nature of the photocathode degradation, and employ multiple surface and bulk analysis techniques to investigate damage mechanisms including sputtering of the Cs-oxidant surface monolayer, other surface chemistry effects, and ion implantation. Surface and bulk analysis studies were conducted on two GaAs photocathodes, which were removed from the JLab FEL DC photoemission gun after delivering electron beam, and two control samples. The analysis techniques include helium ion microscopy, Rutherford backscattering spectrometry (RBS, atomic force microscopy, and secondary ion mass spectrometry (SIMS. In addition, two high-polarization strained superlattice GaAs photocathode samples, one removed from the continuous electron beam accelerator facility (CEBAF photoinjector and one unused, were also analyzed using transmission electron microscopy (TEM and SIMS. It was found that heat cleaning the FEL GaAs wafer introduces surface roughness, which seems to be reduced by prolonged use. The bulk GaAs samples retained a fairly well organized crystalline structure after delivering beam but show evidence of Cs depletion on the surface. Within the precision of the SIMS and RBS measurements, the data showed no indication of hydrogen implantation or lattice damage from ion back bombardment in the bulk GaAs wafers. In contrast, SIMS and TEM measurements of the strained superlattice photocathode show clear crystal damage in the wafer from ion back bombardment.

    The workshop brought together scientists working on the development of x-ray free-electron lasers, and its applications. X-ray free-electron lasers produce high intensity, subpicosecond long, coherent, X-ray pulses, and will open a new frontier to study the structure of matter at the molecular and atomic levels. Some fields of interest are structural changes in chemical reactions, single biological molecule, warm plasmas, nanosystems. Summary of discussions and conclusions of Group 1: Physics and Technology of the XFEL - The main issues that were discussed by the 50 participants in this group were the photo-injector, the production of ultra-short pulses, the effects of wake-fields induced by the electron bunch, the operation at lower charge and emittance, the possibility of harmonic generation and the diagnostics in the undulator. The following is a short summary of the discussions and their conclusions. Summary of discussions and conclusions of Group 2: Science with the XFEL - About 25 people attended sessions to discuss the possible scientific applications of a x-ray FEL. Because of the recent focus on the first experiments with the proposed Linac Coherent Light Source at Stanford, the discussions were mainly focussed on these proposals. The extension of the characteristics beyond the initial stage and the further developments of the source were also part of the program. Six scientific areas were discussed: Atomic Physics, Warm Dense Matter, Femtosecond Chemistry, Imaging/Holography, Bio-molecular Structures and X-Ray Fluctuations Spectroscopy.

    Carbon chars have been synthesized in our laboratory from a variety of starting materials, by means of a highly controlled pyrolysis technique. These chars exhibit electron paramagnetic resonance (EPR) line shapes which change with the local oxygen concentration in a reproducible and stable fashion; they can be calibrated and used for oximetry. Biological stability and low toxicity make chars good sensors for in vivo measurements. Scalar and dipolar interactions of water protons at the surfaces of chars may be utilized to produce dynamic nuclear polarization (DNP) of the 1 H nuclear spin population in conjunction with electron Zeeman pumping. Low-frequency EPR, DNP and DNP-enhanced MRI all show promise as oximetry methods when used with carbon chars. (author)

    An automatic procedure for electron tomography is presented. This procedure is adapted for specimens that can be fashioned into a needle-shaped sample and has been evaluated on inorganic samples. It consists of self-adapting denoising, automatic and accurate alignment including detection and correction of tilt axis, and 3D reconstruction. We propose the exploitation of a large amount of information of an electron tomography acquisition to achieve robust and automatic mixed Poisson–Gaussian noise parameter estimation and denoising using undecimated wavelet transforms. The alignment is made by mixing three techniques, namely (i) cross-correlations between neighboring projections, (ii) common line algorithm to get a precise shift correction in the direction of the tilt axis and (iii) intermediate reconstructions to precisely determine the tilt axis and shift correction in the direction perpendicular to that axis. Mixing alignment techniques turns out to be very efficient and fast. Significant improvements are highlighted in both simulations and real data reconstructions of porous silicon in high angle annular dark field mode and agglomerated silver nanoparticles in incoherent bright field mode. 3D reconstructions obtained with minimal user-intervention present fewer artefacts and less noise, which permits easier and more reliable segmentation and quantitative analysis. After careful sample preparation and data acquisition, the denoising procedure, alignment and reconstruction can be achieved within an hour for a 3D volume of about a hundred million voxels, which is a step toward a more routine use of electron tomography. - Highlights: • Goal: perform a reliable and user-independent 3D electron tomography reconstruction. • Proposed method: self-adapting denoising and alignment prior to 3D reconstruction. • Noise estimation and denoising are performed using wavelet transform. • Tilt axis determination is done automatically as well as projection alignment.

    Mechanical serial block face scanning electron microscopy (SBFSEM) has emerged as a means of obtaining three dimensional (3D) electron images over volumes much larger than possible by focused ion beam (FIB) serial sectioning and at higher spatial resolution than achievable with conventional X-ray computed tomography (CT). Such high resolution 3D electron images can be employed for precisely determining the shape, volume fraction, distribution and connectivity of important microstructural features. While soft (fixed or frozen) biological samples are particularly well suited for nanoscale sectioning using an ultramicrotome, the technique can also produce excellent 3D images at electron microscope resolution in a time and resource-efficient manner for engineering materials. Currently, a lack of appreciation of the capabilities of ultramicrotomy and the operational challenges associated with minimising artefacts for different materials is limiting its wider application to engineering materials. Consequently, this paper outlines the current state of the art for SBFSEM examining in detail how damage is introduced during slicing and highlighting strategies for minimising such damage. A particular focus of the study is the acquisition of 3D images for a variety of metallic and coated systems. - Highlights: • The roughness of the ultramicrotomed block face of AA2024 in Al area was 1.2 nm. • Surface texture associated with chattering was evident in grains with 45° diamond knife. • A 76° rake angle minimises the stress on the block face. • Using the oscillating knife with a cutting speed of 0.04 mms{sup −1} minimised the surface texture. • A variety of material applications were presented.

    An electron energy loss spectral library can be an invaluable tool in materials research from a fundamental as well as a practical standpoint. Although it will not alleviate all the complications associated with quantification, this type of library can help to elucidate details of spectral profiles previously found intractable. This work was supported by the US Department of Energy. The author also wishes to express his gratitude to the organizing committee for partial financial support provided to attend this meeting.

  8. Report of the Panel on Electron Accelerator Facilities, DOE/NSF Nuclear Science Advisory Committee

    International Nuclear Information System (INIS)

    1983-04-01

    This Panel finds that the highest priority for new accelerator construction in the US nuclear physics program is for an electron accelerator of high duty factor capable of producing beams at any energy in the range from 500 to 4000 MeV. After detailed study and consideration of the proposals for such facilities submitted to it, the Panel recommends: that the proposal submitted by the Southeastern University Research Association (SURA) be accepted and funded for the construction of a new National Electron Accelerator Laboratory (NEAL) centering on a 4 GeV linear accelerator-stretcher ring system capable of delivering intense, high duty factor, electron beams in the energy range from 500 to 4000 MeV. Additional recommendations relating to this principal one are to be found in the body of this report. As modified by the Panel consequent to its own studies and analyses, the estimated cost (in 1983 dollars) of the accelerator complex is 111.8 million dollars; of the entire laboratory is 146.8 million dollars; and the operating cost averaged over the first five years of operation is 18.1 million dollars per year. The projected 15 year total cost of the project is 418.3 million dollars. The construction period is estimated to be 4.5 years. The NEAL Laboratory, from the outset will be constructed and managed as a national rather than a regional facility and will provide the United States with a truly unique facility for research in electromagnetic physics

    Berkeley Lab's George Smoot won the 2006 Physics Nobel Prize, together with John Mather of NASA Goddard Space Flight Center, for "the discovery of the blackbody form and anisotropy of the cosmic microwave background radiation." The anisotropy showed as small variations in the map of the early universe. This research looks back into the infant universe and provides a better understanding of the origin of galaxies and stars. The cosmic background radiation is a tool to understand the structure and history of the universe and the structure of space-time. These observations have provided increased support for the big bang theory of the universe's origin. The Cosmic Background Explorer (COBE) NASA satellite, launched in 1989, carries instruments that measured various aspects of cosmic microwave background radiation, and produced the data for these compelling scientific results, which opened up a field that continues very actively today.

    A superconducting magnet for use in an electron cyclotron resonance ion source was developed at the Korea Basic Science Institute. The superconducting magnet is comprised of three solenoids and a hexapole magnet. According to the design value, the solenoid magnets can generate a mirror field, resulting in axial magnetic fields of 3.6 T at the injection area and 2.2 T at the extraction region. A radial field strength of 2.1 T can also be achieved by hexapole magnet on the plasma chamber wall. NbTi superconducting wire was used in the winding process following appropriate techniques for magnet structure. The final assembly of the each magnet involved it being vertically inserted into the cryostat to cool down the temperature using liquid helium. The performance of each solenoid and hexapole magnet was separately verified experimentally. The construction of the superconducting coil, the entire magnet assembly for performance testing and experimental results are reported herein.

    The promises of the ultrahigh-performance properties of superconductivity and Josephson junction technologies have been known for quite some time. This presentation describes the first superconducting electronics and measurement system and its important role as a major tool to advance microwave and millimeter wave technologies. This breakthrough tool is a sampling oscilloscope with 5-ps rise time, 50-μV sensitivity, and a time domain reflectometer with 8-ps rise time. In order to achieve these performance goals, several technological hurdles had to be overcome including perfecting a manufacturing process for building Josephson junction IC chips, developing an innovative cooling technique, developing interfaces and interconnections with bandwidths in excess of 70 GHz, and developing the room-temperature hardware and software necessary to make the instruments convenient, easy to use, easy to learn, in addition to making available functions and features users have come to expect from sophisticated digital test instrumentation. These technological developments are stepping stones leading to the realization of more sophisticated and complex electronic systems satisfying the needs of scientists, technologists, and engineers. The unprecedented speed and sensitivity make it possible to attack new frontiers.

    2017-11-01

    This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The aim is to provide newcomers to the area with insights into: the basic physics of FELs, the qualities of the radiation they produce, the challenges of transmitting that radiation to end users and the diversity of current scientific applications. Initial consideration is given to FEL theory in order to provide the foundation for discussion of FEL output properties and the technical challenges of short-wavelength FELs. This is followed by an overview of existing x-ray FEL facilities, future facilities and FEL frontiers. To provide a context for information in the above sections, a detailed comparison of the photon pulse characteristics of FEL sources with those of other sources of high brightness x-rays is made. A brief summary of FEL beamline design and photon diagnostics then precedes an overview of FEL scientific applications. Recent highlights are covered in sections on structural biology, atomic and molecular physics, photochemistry, non-linear spectroscopy, shock physics, solid density plasmas. A short industrial perspective is also included to emphasise potential in this area. Dedicated to John M J Madey (1943-2016) and Rodolfo Bonifacio (1940-2016) whose perception, drive and perseverance paved the way for the realisation and development of short-wavelength free-electron lasers.

    1976-06-01

    Several techniques for producing positive replicas for materials science applications have been critically examined: 1) Consistent high resolution replicas can be produced by vacuum evaporation of a gold film onto a 'Bioden' (cellulose acetate) negative replica, backing the film with electroplated copper and dissolving the 'Bioden'; 2) negative replicas that are easy to strip and handle may be made using a silicone rubber compound, 'Silastic' RTV 'A' but with highly variable resolution; 3) an epoxy resin, 'Ren', gave good resolution but could not easily be stripped from a specimen surface: it is therefore only suitable for the final (positive) stage of replication. Some possible techniques for obtaining more consistent resolution from 'Silastic' RTV synthetic rubbers are suggested. (author)

    Full Text Available Popularity of the use of free software in the IT industry is much higher than its popular use in educational activities. Disadvantages of free software and problems of its implementation in the educational process is a limiting factor for its use in the education system, however, openness, accessibility and functionality are the main factors for the introduction of free software in the educational process. Nevertheless, for future teachers of mathematics, physics and informatics free software is designed as well as possible because of the specificity of its creation, and therefore, there is a question of the system analysis of the possibilities of using open source software in e-learning for future teachers of mathematics, physics and computer science.

  18. A common body of care: the ethics and politics of teamwork in the operating theater are inseparable.

    Science.gov (United States)

    Bleakley, Alan

    2006-06-01

    In the operating theater, the micro-politics of practice, such as interpersonal communications, are central to patient safety and are intimately tied with values as well as knowledge and skills. Team communication is a shared and distributed work activity. In an era of "professionalism," that must now encompass "interprofessionalism," a virtue ethics framework is often invoked to inform practice choices, with reference to phronesis or practical wisdom. However, such a framework is typically cast in individualistic terms as a character trait, rather than in terms of a distributed quality that may be constituted through intentionally collaborative practice, or is an emerging property of a complex, adaptive system. A virtue ethics approach is a necessary but not sufficient condition for a collaborative bioethics within the operating theater. There is also an ecological imperative-the patient's entry into the household (oikos) of the operating theater invokes the need for "hospitality" as a form of ethical practice.

    Knight, Victoria Floyd

    Supported electronic text (eText), or text that has been altered to increase access and provide support to learners, may promote comprehension of science content for students with disabilities. According to CAST, Book Builder(TM) uses supported eText to promote reading for meaning for all students. Although little research has been conducted in the area of supported eText for students with autism spectrum disorders (ASD), technology (e.g., computer assisted instruction) has been used for over 35 years to instruct students with ASD in academic areas. The purpose of this study was to evaluate the effects of a supported eText and explicit instruction on the science vocabulary and comprehension of four middle school students with ASD. Researchers used a multiple probe across participants design to evaluate the Book Builder (TM) program on measures of vocabulary, literal comprehension, and application questions. Results indicated a functional relation between the Book Builder(TM) and explicit instruction (i.e., model-lead-test, examples and non-examples, and referral to the definition) and the number of correct responses on the probe. In addition, students were able to generalize concepts to untrained exemplars. Finally, teachers and students validate the program as practical and useful.

    This thesis reports on the study of the acoustic properties of 18 theaters belonging to the Andalusian historical and architectural heritage. These theaters have undergone recent renovations to modernize and equip them appropriately. Coincident with this work, evaluations and qualification assessments with regard to their acoustic properties have been carried out for the individual theaters and for the group as a whole. Data measurements for this purpose consisted of acoustic measurements in situ, both before the renovation and after the renovation. These results have been compared with computer simulations of sound fields. Variables and parameters considered include the following: reverberation time, rapid speech transition index, back-ground noise, definition, clarity, strength, lateral efficiency, interaural cross-correlation coefficient, volume/seat ratio, volume/audience-area ratio. Based on the measurements and analysis, general conclusions are given in regard to the acoustic performance of theaters whose typology and size are comparable to those that were used in this study (between 800 and 8000 cubic meters). It is noted that these properties are comparable to those of the majority of European theaters. The results and conclusions are presented so that they should be of interest to architectural acoustics practitioners and to architects who are involved in the planning of renovation projects for theaters Thesis advisors: Juan J.

    This report describes the methodology and results of independent verification and validation performed on a combat model in its design stage. The combat model is the Future Theater Level Model (FTLM), under development by The Joint Staff/J-8. J-8 has undertaken its development to provide an analysis tool that addresses the uncertainties of combat more directly than previous models and yields more rapid study results. The methodology adopted for this verification and validation consisted of document analyses. Included were detailed examination of the FTLM design documents (at all stages of development), the FTLM Mission Needs Statement, and selected documentation for other theater level combat models. These documents were compared to assess the FTLM as to its design stage, its purpose as an analytical combat model, and its capabilities as specified in the Mission Needs Statement. The conceptual design passed those tests. The recommendations included specific modifications as well as a recommendation for continued development. The methodology is significant because independent verification and validation have not been previously reported as being performed on a combat model in its design stage. The results are significant because The Joint Staff/J-8 will be using the recommendations from this study in determining whether to proceed with develop of the model.

    This paper presents ceramic substrates and thick-film metallization based packaging technologies in development for 500C silicon carbide (SiC) electronics and sensors. Prototype high temperature ceramic chip-level packages and printed circuit boards (PCBs) based on ceramic substrates of aluminum oxide (Al2O3) and aluminum nitride (AlN) have been designed and fabricated. These ceramic substrate-based chip-level packages with gold (Au) thick-film metallization have been electrically characterized at temperatures up to 550C. The 96 alumina packaging system composed of chip-level packages and PCBs has been successfully tested with high temperature SiC discrete transistor devices at 500C for over 10,000 hours. In addition to tests in a laboratory environment, a SiC junction field-effect-transistor (JFET) with a packaging system composed of a 96 alumina chip-level package and an alumina printed circuit board was tested on low earth orbit for eighteen months via a NASA International Space Station experiment. In addition to packaging systems for electronics, a spark-plug type sensor package based on this high temperature interconnection system for high temperature SiC capacitive pressure sensors was also developed and tested. In order to further significantly improve the performance of packaging system for higher packaging density, higher operation frequency, power rating, and even higher temperatures, some fundamental material challenges must be addressed. This presentation will discuss previous development and some of the challenges in material science (technology) to improve high temperature dielectrics for packaging applications.

    Full Text Available Theaterplakate gehören zur Tätigkeit des Theaters. Anfangs erfüllten sie eine reine Gebrauchsfunktion, indem sie über ein kulturelles Ereignis informierten, das an einem bestimmten Tag, zu einer bestimmten Uhrzeit, an einem bestimmten Ort stattfinden wird. Mit der Zeit bekamen sie jedoch die Eigenschaften eines Zeugens aus der Vergangenheit, indem sie die Geschichte ihres Urhebers zeigten, das Profil seiner Tätigkeit, die in seiner Struktur vor sich gehenden Veränderungen. Die Wurzeln der Theaterplakate sind schon in der Antike zu suchen, sie wurden von Ägyptern, Römern und Griechen geschaffen. Das älteste neuzeitliche Plakat erschien 1429 in London und ist heute ein Exponat im Londoner Theatermuseum. Die Geschichte der polnischen Plakate reicht bis ins 16. oder 17. Jahrhundert zurück, hier sind sich die Forscher nicht einig, und ist entweder mit einem Jesuitenkollegium oder mit dem königlichen Theater verbunden. Die im Text analysierten Thorner Plakate stammen aus den Jahren 1922-1975 und werden in den Sammlungen der Kopernikus-Bücherei und in den Beständen des Staatsarchivs in Thorn aufbewahrt. Geschaffen wurden sie vom Theater in Thorn. Heute ist es das Wilam-Horzyca-Theater, doch sein Name, sein Tätigkeitsfeld, seine Organisationsstruktur und auch sein Profil und die Art seiner Tätigkeit änderten sich im Laufe der besprochenen Jahre vielmals. Die Plakate wurden in chronologischer Ordnung mit einer Aufteilung in Gruppen besprochen. Die Autorinnen beachteten den Inhalt, seine Anordnung und die Form der Aufzeichnung, das Format der Plakate, ihre Farbgebung, Ornamentik und die verwendete Ikonographie. Jede Gruppe wurde detailliert besprochen und illustriert. Nicht allein das Theater in Thorn schuf in der Stadt Theaterplakate. Eine ähnliche aktenkundliche Analyse lässt sich in Bezug auf das Puppentheater „Baj Pomorski” durchführen, doch ist das schon Material für einen gesonderten Artikel.

  19. Charitable collaborations in Bronzeville, 1928-1944: the "Chicago Defender" and the Regal Theater.

    2011-01-01

    In the twentieth century, race-based residential and commercial segregation that supported racial oppression and inequality became an elemental characteristic of urban black communities. Conflict-ridden, black-white relationships were common. However, the Chicago Defender Charities, Inc., the entity that sponsors the largest African American parade in the country and that emerged in 1947, embodied a tradition of charitable giving, self-help, and community service initiated in 1921 by Chicago Defender newspaper founder and editor, Robert S. Abbott. The foundation of this charitable tradition matured as a result of an early and sustained collaboration between Chicago’s white-owned Regal Theater and the black-owned Chicago Defender newspaper. Thus, in segregated African American communities, black and white commercial institutions, under certain conditions, were able to find important points of collaboration to uplift the African American communities of which they were a part.

    Full Text Available Training medical students to understand the effects of culture and marginalization on health outcomes is important to the future health of increasingly diverse populations. We devised and evaluated a short training module on working with diversity to challenge students’ thinking about the role of both patient and practitioner culture in health outcomes. The workshop combined didactic teaching about culture as a social determinant of health using the cultural humility model, interactive exercises, and applied theater techniques. We evaluated changes in the students’ perceptions and attitudes over time using the Reaction to Diversity Inventory. There was initial significant improvement. Women and students with no past diversity training responded best. However, scores largely reverted to baseline over 12 months.

    This case report describes the first case in intraoperative magnetic resonance imaging operating theater (iMRI OT) (BrainSuite®) of awake craniotomy for frontal lobe glioma excision in a 24-year-old man undergoing eloquent cortex language mapping intraoperatively. As he was very motivated to take pictures of him while being operated upon, the authors adapted conscious sedation technique with variable depth according to Ramsey's scale, in order to revert to awake state to perform the intended neurosurgical procedure. The patient tolerated the situation satisfactorily and was cooperative till the finish, without any event. We elicit in this report the special environment of iMRI OT for lengthy operation in pinned fixed patient having craniotomy. PMID:25885085

    Stigma impacts >50% of persons with epilepsy (PWE) and is a key factory in quality of life. Stigma can be both enacted (external factors) and felt (internal factors). In this article, felt/perceived stigma is more broadly defined as a combination of internal factors and perceptions of external factors. Secondary perceived stigma is felt/perceived stigma by a third party. A key, but often underappreciated, consideration in felt/perceived stigma may occur when a seemingly innocuous statement by a speaker is perceived as stigmatizing by the PWE and/or even by an unintended third party. This autobiographic short report addresses secondary perceived stigma in a social setting, the theater. Copyright © 2016 Elsevier Inc. All rights reserved.

    Just as data from civilian trauma registries have been used to benchmark and evaluate civilian trauma care, data contained within the Joint Theater Trauma Registry (JTTR) present a unique opportunity to benchmark combat care. Using the iterative steps of the benchmarking process, we evaluated data in the JTTR for suitability and established benchmarks for 24-hour mortality in casualties with polytrauma and a moderate or severe blunt traumatic brain injury (TBI). Mortality at 24 hours was greatest in those with polytrauma and a severe blunt TBI. No mortality was seen in casualties with polytrauma and a moderate blunt TBI. Secondary insults after TBI, especially hypothermia and hypoxemia, increased the odds of 24-hour mortality. Data contained in the JTTR were found to be suitable for establishing benchmarks. JTTR data may be useful in establishing benchmarks for other outcomes and types of combat injuries.

    Currently, networking has not progressed in the treatment room. Almost every medical device in the treatment room operates as a stand-alone device. In this project, we aim to develop a networked operating room called "Smart Cyber Operating Theater (SCOT)". Medical devices are connected using Open Resource interface for the Network (ORiN) technology. In this paper, we describe the concept of the SCOT project. SCOT is integrated using the communication interface ORiN, which was originally developed for industry. One feature of ORiN is that the system can be constructed flexibly. ORiN creates abstracts of the same type of devices and increases the robustness of the system for device exchange. By using ORiN technology, we are developing new applications, such as decision-making navigation or a precision guided treatment system.

    Although a number of existing reviews document the health and social benefits of arts participation by older people, there are none which focus specifically on theater and drama. This article presents the findings of a study conducted as part of the UK's Arts and Humanities Research Council "Cultural Value Project." The 2-year (2013-2015) "Cultural Value Project" sought to make a major contribution to how we think about the value of arts and culture to individuals and to society. It made 72 awards: 19 critical reviews of existing bodies of research, 46 research development awards to carry out new research, and 7 expert workshop awards to facilitate discussions among academics and practitioners. Together, these awards explored the components of cultural value and the ways in which cultural value is evidenced and evaluated. Following an extensive search of academic databases and E-mail requests via relevant organizations and networks, 77 publications formed the basis for our own critical review. Our findings highlight the benefits and value of older people's theater and drama participation on health and well-being, group relationships, learning and creativity, and draw attention to the importance of the esthetic value and quality of older people's drama. Despite the recent surge of interest in this field (a third of the reviewed literature was published between 2010 and 2014), we suggest that there are multiple areas for further research. © The Author 2016.

  8. What physiological changes and cerebral traces tell us about adhesion to fiction during theater-watching?

    Directory of Open Access Journals (Sweden)

    Marie-Noëlle Metz-Lutz

    2010-08-01

    Full Text Available Live theater is typically designed to alter the state of mind of the audience. Indeed, the perceptual inputs issuing from a live theatrical performance are intended to represent something else, and the actions, emphasised by the writing and staging, are the key prompting the adhesion of viewers to fiction, i.e. their belief that it is real. This phenomenon raises the issue of the cognitive processes governing access to a fictional reality during live theater and of their cerebral underpinnings. To get insight into the physiological substrates of adhesion we recreated the peculiar context of watching live drama in a functional magnetic resonance imaging experiment, with simultaneous recording of heart activity. The instants of adhesion were defined as the co-occurrence of theatrical events determined a priori by the stage director and the spectators’ offline reports of moments when fiction acted as reality. These data served to specify, for each spectator, individual fMRI time-series, used in a random-effect group analysis to define the pattern of brain response to theatrical events. The changes in this pattern related to subjects’ adhesion to fiction, were investigated using a region of interest analysis. The results showed that adhesion to theatrical events correlated with increased activity in the left BA47 and pSTS, together with a decrease in dynamic heart rate variability, leading us to discuss the hypothesis of subtle changes in the subjects’ state of awareness, enabling them to mentally dissociate physical and mental (drama-viewing experiences, to account for the phenomenon of adhesion to dramatic fiction.

    Musical theater performers are the "triathletes" in the performing arts. The field requires versatility in a combination of skills including dancing, singing, and drama in a high frequency of performances. The aim of this study was to analyze and evaluate the health situation of musical theater students using a complete musical educational institute as an example (n = 37). The basis for the evaluation was a questionnaire survey (standardized F 1000). All students of the school participated (20 males, 17 females). Of the students, 62% have a part-time job for financial reasons, and 67.7% state only a "partial satisfaction" with their body. Regarding injury, 45.9% claim to sustain an orthopaedic injury up to twice a year, and 29.7% up to three or four times. A total of 49 acute injuries (1.3/student) and 42 chronic complaints (1.1/student) were stated. The lower extremity was the most common acutely injured region (65.3%), followed by the spine (16.3%) and upper extremity (14.3%). Of chronic complaints, the lumbar spine was the most commonly affected area, followed by the hip joint and pelvic area. Thirty-three and 24% of acute injuries occurred during "spins" and/or "stretching," respectively. There were various causes for physical and mental problems. The results show both parallels and differences to the relevant literature. It is shown that health hazards already arise in the education of musical performers. This provides particulars for the implementation of injury prevention measures during the theoretical and practical education of musical students.

    The emergence of electronic nicotine delivery systems (ENDS, or "e-cigarettes") has resulted in nicotine and tobacco scientists committing increased resources to studying these products. Despite this surge of research on various topics related to e-cigarettes, it is important to characterize the evolving e-cigarette research landscape as a way to identify important future research directions. The purpose of this review was to broadly categorize published scholarly work on e-cigarettes using a structured, multi-level coding scheme. A systematic literature search was conducted to collect articles on e-cigarettes that were published in peer-reviewed journals from 2006 through 2014. Studies were classified through 3 coding waves. Articles were first divided into research reports, literature reviews and opinions/editorials. Research reports were further categorized to determine the proportion of these studies using human participants. Finally, human studies were classified based on their methodologies: descriptive, predictive, explanatory, and intervention. Research reports (n=224) and opinions/editorials (n=248) were published at similar rates during this time period. All types of articles showed exponential rates of increase in more recent years. 76.4% of human research studies were descriptive in nature, with very little research employing experimental (6.8%) or intervention-based methodologies (5.4%). This review reinforces the idea that e-cigarettes are a disruptive technology exerting substantial influence on nicotine and tobacco science. This review also suggests that opinions on e-cigarettes may be outpacing our scientific understanding of these devices. Our findings highlight the need for more e-cigarette research involving experimental, intervention, and longitudinal designs. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available This article presents an overview of "Performative Social Science," which is defined as the deployment of different forms of artistic performance in the execution of a scientific project. Such forms may include art, theater, poetry, music, dance, photography, fiction writing, and multi-media applications. Performative research practices are in their developmental stage, with most of the major work appearing in the last two decades. Frequently based on a social constructionist metatheory, supporters reject a realist, or mapping view of representation, and explore varieties of expressive forms for constructing worlds relevant to the social sciences. The performative orientation often relies on a dramaturgical approach that encompasses value-laden, emotionally charged topics and presentations. Social scientists invested in social justice issues and political perspectives have been especially drawn to this approach. Performative social science invites productive collaborations among various disciplinary fields and between the sciences and arts. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1101119

    Guerilla Science a non-profit science education organization that, since 2007, has brought live events to unconventional venues for science, such as music festivals, art galleries, banquets, department stores and theaters. Guerilla Science sets science free by taking it out of the lab and into the traditional domains of the arts. By producing events that mix science with art, music and play, they create unique opportunities for adult audiences to experience science in unorthodox ways, such as interactive events, games, live experiments, demonstrations and performances by academics, artists, musicians, actors, and professional science communicators. Much of Guerilla Science's work has focused on astrophysical and terrestrial plasmas, and this presentation will provide an overview of Guerilla Science's work in this area. Guerilla Science has produced over twenty events, receiving international media coverage, and directly reached over fifteen thousand members of the public.

    The scientific complexities of global climate change, with wide-ranging economic and social significance, create an intellectual challenge that mandates greater public understanding of climate change research and the concurrent ability to make informed decisions. The critical need for an engaged, science literate public has been repeatedly emphasized by multi-disciplinary entities like the Intergovernmental Panel on Climate Change (IPCC), the National Academies (Rising Above the Gathering Storm report), and the interagency group responsible for the recently updated Climate Literacy: The Essential Principles of Climate Science. There is a clear need for an American public that is climate literate and for K-12 teachers confident in teaching relevant science content. A key goal in the creation of a climate literate society is to enhance teachers’ knowledge of global climate change through a national, scalable, and sustainable professional development system, using compelling climate science data and resources to stimulate inquiry-based student interest in science, technology, engineering, and mathematics (STEM). This session will explore innovative e-learning technologies to address the limitations of one-time, face-to-face workshops, thereby adding significant sustainability and scalability. The resources developed will help teachers sift through the vast volume of global climate change information and provide research-based, high-quality science content and pedagogical information to help teachers effectively teach their students about the complex issues surrounding global climate change. The Learning Center is NSTA's e-professional development portal to help the nations teachers and informal educators learn about the scientific complexities of global climate change through research-based techniques and is proven to significantly improve teacher science content knowledge.

    (Abstract only) New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth was mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing, scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1-5, following the AAVSO/AAS meetings. World Science Festival was founded by Dr. Brian Greene, Columbia University, and is operated through the World Science Foundation. The Festival is "saturation science" all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in "science" venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend from hard science, with lectures like those by us astronomers, to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee. While almost all events are on Manhattan, effort has been made to geographically disperse them, even to the outer boroughs. The grand finale of World Science Festival is a street fair in Washington Square. Science centers in booths, tents, and pavilions highlight their work. In past years this fair drew 100,000 to 150,000 visitors. The entire Festival attracts about a quarter-million attendees. NYSkies is a proud participant at the Washington Square fair. It interprets the "Earth to the Universe" display, debuting during IYA-2009. Attendance at "Earth..." on just the day of the fair plausibly is half of all visitors in America. The presentation shows the scale and scope of World Science Festival, its relation to the City, and how our astronomers work with it.

    Most critically ill injured patients are transported out of the theater by Critical Care Air Transport Teams (CCATTs). Fever after trauma is correlated with surgical complications and infection. The purposes of this study are to identify the incidence of elevated temperature in patients managed in the CCATT environment and to describe the complications reported and the treatments used in these patients. We performed a retrospective review of available records of trauma patients from the combat theater between March 1, 2009, and March 31, 2010, who were transported by the US Air Force CCATT and had an incidence of hyperthermia. We then divided the cohort into 2 groups, patients transported with an elevation in temperature greater than 100.4°F and patients with no documented elevation in temperature. We used a standardized, secure electronic data collection form to abstract the outcomes. Descriptive data collected included injury type, temperature, use of a mechanical ventilator, cooling treatment modalities, antipyretics, intravenous fluid administration, and use of blood products. We also evaluated the incidence of complications during the transport in patients who had a recorded elevation in temperature greater than 100.4°F. A total of 248 trauma patients met the inclusion criteria, and 101 trauma patients (40%) had fever. The mean age was 28 years, and 98% of patients were men. The mechanism of injury was an explosion in 156 patients (63%), blunt injury in 11 (4%), and penetrating injury in 45 (18%), whereas other trauma-related injuries accounted for 36 patients (15%). Of the patients, 209 (84%) had battle-related injuries and 39 (16%) had non-battle-related injuries. Traumatic brain injury was found in 24 patients (24%) with an incidence of elevated temperature. The mean temperature was 101.6°F (range, 100.5°F-103.9°F). After evaluation of therapies and treatments, 80 trauma patients (51%) were intubated on a mechanical ventilator (P cooling interventions

    Airborne bacterial contamination poses a risk for surgical site infection, and routine surveillance of airborne bacteria is important. Traditional methods for detecting airborne bacteria are time consuming and strenuous. Measurement of biologic particle concentrations using a fluorescent particle counter is a novel method for evaluating air quality. The current study was to determine whether the number of biologic particles detected by the fluorescent particle counter can be used to indicate airborne bacterial counts in operating rooms. The study was performed in an operating theater at a university hospital in Hefei, China. The number of airborne biologic particles every minute was quantified using a fluorescent particle counter. Microbiologic air sampling was performed every 30 minutes using an Andersen air sampler (Pusong Electronic Instruments, Changzhou, China). Correlations between the 2 different methods were analyzed by Pearson correlation coefficients. A significant correlation was observed between biologic particle and bacterial counts (Pearson correlation coefficient = 0.76), and the counting results from 2 methods both increased substantially between operations, corresponding with human movements in the operating room. Fluorescent particle counters show potential as important tools for monitoring bacterial contamination in operating theatres.

  18. HDTV versus electronic cinema

    Science.gov (United States)

    1998-12-01

    We are on the brink of transforming the movie theatre with electronic cinema. Technologies are converging to make true electronic cinema, with a 'film look,' possible for the first time. In order to realize the possibilities, we must leverage current technologies in video compression, electronic projection, digital storage, and digital networks. All these technologies have only recently improved sufficiently to make their use in the electronic cinema worthwhile. Video compression, such as MPEG-2, is designed to overcome the limitations of video, primarily limited bandwidth. As a result, although HDTV offers a serious challenge to film-based cinema, it falls short in a number of areas, such as color depth. Freed from the constraints of video transmission, and using the recently improved technologies available, electronic cinema can move beyond video; Although movies will have to be compressed for some time, what is needed is a concept of 'cinema compression,' rather than video compression. Electronic cinema will open up vast new possibilities for viewing experiences at the theater, while at the same time offering up the potential for new economies in the movie industry.

    Although the ventilation system is widely employed in the operating theater, a strictly sterile surgical environment still cannot be ensured because of laminar disturbance, which is mainly caused by the surgical lighting system. Abandoning traditional products, we propose an LED surgical lighting system, which can alleviate the laminar disturbance and provide an appropriate lighting condition for surgery. It contains a certain amount of LED lens units, which are embedded in the ceiling and arranged around the air supply smallpox. The LED lens unit integrated with an LED light source and a free-form lens is required to produce a uniform circular illumination with a large tolerance to the change of lighting distance. To achieve such a dedicated lens, two free-form refractive surfaces, which are converted into two ordinary differential equations by the design method presented in this paper, are used to deflect the rays. The results show that the LED surgical lighting system can provide an excellent illumination environment for surgery, and, apparently, the laminar disturbance also can be relieved.

    In many parts of the world, young adult women have higher levels of common mental disorders than men. The exacerbation of domestic violence (DV) by migration is a salient social determinant of poor mental health. Ecological models describe factors contributing to DV as operating at individual, family, cultural, and societal levels. We explored the interplay among these factors in an Indian community living in Melbourne, Australia, in a qualitative participatory action research study using a modified Forum Theater approach. We here present findings on connections between migration, societal factors, and social/family/cultural factors in DV. The study captured the voices of women living in the community as they describe how DV contributes to their emotional difficulties. Improved understanding of the sociocultural dynamics of DV and the associated social distress in this migrant Indian community can be used to guide the development of culturally sensitive prevention and response programs to assist migrant women from the Indian subcontinent who present with psychopathology and suicidal behaviors associated with DV. © The Author(s) 2015.

    Full Text Available The Opera of the National Theater in Belgrade was founded in 1920, but it is well known that opera performances were held long before its official opening. Despite the fact that this is the sole opera house in Belgrade (and one of the only two in Serbia, as well as the fact that it did not face any strong audience fluctuation, it is unusual that no one ever tried to investigate and profile its audience. During the last decades we were witnessing the popularization of the opera via various medias, as well as development and extention of the music industry, which surely changed its social status. The aim of the investigation that is going to be presented is to discover if this social life of opera changed its audience and does it still consists of - according to stereotypes - elderly, high educated individuals of certain professions and high material standards, i.e. at which level the opera is present in the private and public sphere of their lives.

  4. IntertextualitY and discourse in Dea Loher’s Theater

    Full Text Available Discourse is made of several voices, a premise that was announced since Bakhtin’s studies. The advances in the field of intertextuality allowed a wider specification of the term and broaden the discussion of many different occurrence of the intertext in literature. The work of a German contemporary playwright, Dea Loher, brings the recurrence of intertext, and the present paper aims to investigate this manifestation in two of her plays, Olgas Raum and Licht. Loher uses citation, references and allusions, cutting pieces of other texts and pasting them into her writing. This game of cutting and pasting is also visible inside her aesthetic, as she uses elements that are part of other theatrical aesthetics and adapts them in her work, creating an original style. Representing the political side of theater, Loher provides her reader with the possibility of reflecting and, in the considered two plays, she does it through the deconstruction of the canonic discourse, showing how discourses are made and how they are connected to power maintenance. This way, intertext, the hybrid aesthetic and other aesthetical and linguistic resources are organized to receive these political themes that come to the reader as questions and inquires.

    Full Text Available Organizational memory studies (OMS frame memory in a managerial mode, treating it as a data storage, limiting the scope from wider field of social memory studies. There is a lack of understanding about how the process of institutional forgetting works and how some memories stay a part of oral narratives and communicative social memory while they are omitted from the official memory represented by the official documents and events of remembering. Inspired by Paul Connerton’s article on the typology of forgetting we explore his typology in selected case studies of three public theaters located in Belgrade, focusing on remembering policy and practices investigating if a type of forgetting typical for a state/society/nation level is possible to be applied in the context of a cultural organization. We agree with Wessel and Moulds that developing common language and terminology would be important and beneficial for cross disciplinary dialogue. In this sense, the study shows how the typology of forgetting in societies can be applied and developed in the organizational memory studies and cultural management. The focus of the research is the dynamics of remembering and forgetting explored through analysis of the interaction between changing context, official institutional memories, and social communicative memories.

    The knowledge-based methodologies for assessing the structural safety and vulnerability of historical buildings are based on the application of an operational approach that is divided into several phases including historical research, the execution of non-destructive or moderately destructive investigations, monitoring and structural analysis. Monitoring is a useful tool to be used throughout the whole process of knowledge not only in the preliminary diagnosis, but also for the control of the quality and effectiveness of the interventions, in the context of appropriate conservation programs e protection of the object being studied. From this point of view, monitoring becomes essential for: (i) the evaluation of the real structural behavior and the identification of vulnerabilities, prior to the execution of any intervention; (ii) minimization and optimization of interventions, firstly by providing indications regarding those that are not necessary and / or invasive. This methodology has been recently applied and valid from the authors to an archaeological site of particular relevance: the Roman Theater of Verona. The deepening of the knowledge phase (historical analysis, survey, study of the subsoil, properties of materials), combined with the installation of a permanent monitoring system and the structural modeling, allowed to obtain a reliable assessment of the site's vulnerabilities with the aim of guaranteeing in an effective and careful protection and enhancement.

  7. Tourniquets and exsanguinators: a potential source of infection in the orthopedic operating theater?

    2009-04-01

    BACKGROUND AND PURPOSE: Fomites are increasingly being recognised as a source of hospital-acquired infection. We have therefore assessed tourniquets and exsanguinators for the presence of bacterial pathogens in 1 elective and 2 trauma orthopedic hospitals. MATERIAL AND METHODS: Swabs were taken prior to and after decontaminating these devices with 1 of 3 different cleaning modalities. These were then assessed for colony counts and organisms identified. RESULTS: Bacteria commonly implicated in surgical site infections such as coagulase-negative staphylococci, Staphylococcus aureus and Proteus spp. were prevalent. We also found a resistant strain of Acinetobacter and Candida. Exsanguinators were the most heavily contaminated devices, and colony counts in the trauma hospitals were up to 400% higher than in the elective hospital. Alcohol- and non-alcohol-based sterile wipes were both highly effective in decontaminating the devices. INTERPRETATION: Infectious organisms reside on the tourniquets and exsanguinators presently used in the orthopedic theater. These fomites may possibly be a source of surgical site infection. We have demonstrated a simple and effective means of decontaminating these devices between cases.

    Full Text Available Objective: To understand the importance of theater as an occupational therapy resource for the prevention of substance abuse by teens enrolled in a community-based psychosocial project. Methods: A qualitative, descriptive study with a critical reflection approach held at a community center in the Community of Dendê, Fortaleza-Ceará, Data were collected from March to May 2009 in a group of ten (10 teenagers of both sexes, aged 12 to 18 years, who lived in socially vulnerable situations and participated in the GESTTO group (Group of Socio-theatrical Expressions in Occupational Therapy. A structured interview was used with a simple observation of groups of theatrical activities and a field book. The analysis of the empirical material was based on Orlandi’s discourse analysis. Results: It was found that theatrical activities used as an occupational therapy resource constitute a powerful tool for the prevention of substance abuse, promoting increased self-esteem, the restructuring of the model of social identity, and the discovery of potentialities and abilities by teenagers so that they can become peer educators for the prevention of substance abuse in the community. Conclusion: The theatrical activity provided teenagers with a clear understanding of the use and abuse of illicit drugs, making them more sensitive to prevention and self-identity, making a significant change in their lives. doi:10.5020/18061230.2013.p333

    Design and construction of an electron linear accelerator by Institute for Research in Fundamental Science (IPM) is considered as Iran’s first attempt to construct such an accelerator. In order to design a linear accelerating tube, after defining the accelerating tube and buncher geometries, RF input and output couplers must be designed. In this article, firstly, a brief report on the specifications of an S-band electron linear accelerator which is in progress in the school of particles and accelerators is presented and then, the design process and construction reports of the couplers required for this accelerator are described. Through performing necessary calculations and tuning the coupling factor and resonant frequency, couplers with desired specification have been fabricated by shrinking method. The final obtained coupling factor and resonant frequency have been respectively 1.05 and 2997 MHz for the first coupler, and 0.98 and 2996.9 MHz for the second one that are close to calculation results

  14. Art in the Service of Science

    Asmus, J. F.

    In fields such as studio art, art conservation, archaeology, anthropology, music, and architecture it is often understood that many of the advances emerge from the introduction of new developments from science and technology. Scientific research is often justified on the basis of its past as well as potential future fallout into other endeavors as diverse as medicine, manufacturing, and the humanities. The diffusion of scientific innovation into the practice of art conservation has been punctuated by the introduction of a series of diverse technologies. Trace element and isotopic analyses, infrared imaging, ultraviolet fluorescence inspection, advanced coatings and adhesives, scanning electron microscopy, and photon/electron microprobes are notable examples. For the past thirty years various laser technologies have demonstrated utility in the practice of art conservation, as well. These include photon cleaning and divestment, holographic display and nondestructive analysis, surface characterization through laser fluorescence, radiation scattering and absorption, as well as laser-induced ultrasound. At the dawn of laser technology's introduction into the art conservation field (1972-74) the Center for Art/Science Studies (CASS) was established at the University of California, San Diego (UCSD) with the hope of accelerating and broadening the diffusion of scientific developments into art conservation practice. Surprisingly, one of the first events in the CASS/UCSD transpired when a Visual Arts Department student employed a primitive laser statue cleaner to "correct" a silk-screen print. In the course of maintaining her laser this art student discovered a dramatically improved method for aligning the complex optical beam train by utilizing her artistic training. A few months later another CASS/UCSD student in the Photographic Arts Program (while modifying a ruby laser to experiment with theater-lighting special effects) discovered an improved laser beam

    Full Text Available Background: Quality communication skills and increased multicultural sensitivity are universal goals, yet teaching them have remained a challenge for educators. Objective: To document the process and participant responses to Interactive Theater when used as a method to teach physician-patient communication and cross-cultural competency. Design, setting, and participants: Three projects are reported. They were collaborations between Theater Delta, the UNC Center for Functional GI and Motility Disorders, the Rome Foundation, the World Gastroenterology Organization, and the American Gastroenterological Association. Outcome measures: 8 forced choice and 6 open ended were collected from each participant using a post-performance evaluation form. Results: Responses to the 8 indicators relating to a positive experience participating in the Interactive Theater. The vast majority either agreed or strongly agreed with the statements on the evaluation form. Written comments explained why. Conclusions: Data indicates that Interactive Theater stimulates constructive dialogue, analysis, solutions, and intended behavior change with regard to communication skills and adapting to patients from multicultural backgrounds. Interactive Theater directly focuses on communication itself (active listening, empathy, recognizing cultural differences, etc. and shows promise as an effective way to improve awareness and skills around these issues.

    Traditionally, surgical education has been confined to operating and lecture theaters. Access to the World Wide Web and services, such as YouTube and iTunes has expanded enormously. Each week throughout Ireland, nonconsultant hospital doctors work hard to create presentations for surgical teaching. Once presented, these valuable presentations are often never used again. We aimed to compile surgical presentations online and establish a new online surgical education tool. We also sought to measure the effect of this educational tool on surgical presentation quality. Surgical presentations from Cork University Hospital and Beaumont Hospital presented between January 2010 and April 2011 were uploaded to http://www.pilgrimshospital.com/presentations. A YouTube channel and iTunes application were created. Web site hits were monitored. Quality of presentations was assessed by 4 independent senior surgical judges using a validated PowerPoint assessment form. Judges were randomly given 6 presentations; 3 presentations were pre-web site setup and 3 were post-web site setup. Once uploading commenced, presenters were informed. A total of 89 presentations have been uploaded to date. This includes 55 cases, 17 journal club, and 17 short bullet presentations. This has been associated with 46,037 web site page views. Establishment of the web site was associated with a significant improvement in the quality of presentations. Mean scores for pre- and post-web site group were 6.2 vs 7.7 out of 9 respectively, p = 0.037. This novel educational tool provides a unique method to enable surgical education become more accessible to trainees, while also improving the overall quality of surgical teaching PowerPoint presentations.

    The purpose of the Health Sciences Library System (HSLS) electronic book (e-book) study was to assess use, and factors affecting use, of e-books by all patron groups of an academic health sciences library serving both university and health system-affiliated patrons. A web-based survey was distributed to a random sample (n=5,292) of holders of library remote access passwords. A total of 871 completed and 108 partially completed surveys were received, for an approximate response rate of 16.5%-18.5%, with all user groups represented. Descriptive and chi-square analysis was done using SPSS 17. Library e-books were used by 55.4% of respondents. Use by role varied: 21.3% of faculty reported having assigned all or part of an e-book for class readings, while 86% of interns, residents, and fellows reported using an e-book to support clinical care. Respondents preferred print for textbooks and manuals and electronic format for research protocols, pharmaceutical, and reference books, but indicated high flexibility about format choice. They rated printing and saving e-book content as more important than annotation, highlighting, and bookmarking features. Respondents' willingness to use alternate formats, if convenient, suggests that libraries can selectively reduce title duplication between print and e-books and still support library user information needs, especially if publishers provide features that users want. Marketing and user education may increase use of e-book collections.

  20. The pedagogical emancipation of Jacques Rancière and the theater of the oppressed as a re-distribution of the sensible

    Pedro Augusto Boal Costa Gomes

    2015-07-01

    Full Text Available The aim of this paper is to demonstrate how Jaques Rancière’s pedagogical theory, intellectual emancipation, esthetics and politics as used as a basis to understand the Theater of the Oppressed as a form of re-distribution of the sensible inside contemporary society. The Theater of the Oppressed practices, able to provide social and political emancipation with esthetical resources, can renew the ways of sensible appropriation, as well as the snip of this appropriation. The “intelligentsia equality” assumption, allied to several mechanisms that can give the oppressed people the artistic means of production, will be exposed here as a voice capable of answering the contemporary challenges of political emancipation. This article has the intention to articulate an interdisciplinary perspective, because it works with conceptions from politics, philosophy, theater and education.

    Sacral Theater has been developed for the toroid magnet Atlas of the CERN LHC project. This three dimensional calculations code calculates the propagation of the transition of a superconducting coil in 25 m long hippodrome. Procedures to study low currents have been included. This work is a part of the magnet safety system because the coils protection is made by warmers activating the quench propagation in case of default detection. This allows the complete dissipation of storage energy that can reach 1080 MJ on Atlas. (N.C.)

    Sun protection in childhood is important to reduce the risk of developing skin cancer later in life. The "Periods-of-Life-Program" for primary prevention of skin cancer introduces a combination of individual and environmental interventions for the preschool period. Within this pilot study, an intervention group received cognitive-behavioral and environmental interventions. A control group had solely received the environmental intervention, and a wait-control group received no intervention. Nursery school children (n = 80, 3 to 6 years of age) of four nursery schools were randomly assigned to these groups on school level. The ability of the cognitive-behavioral intervention (a theater play) to enhance sun protection knowledge was examined. The theater play improved knowledge over all age groups (p < .05 η(2) = .06). Age-specific analyses showed better results for children aged 5 to 6 (p < .05 η(2) = .20) compared to children aged 3 to 4 years (p = .17 η(2) = .04). In combining cognitive-behavioral and environmental interventions, the "Periods-of-Life-Program" is a promising strategy for primary prevention of skin cancer.

    2010-02-01

    Exposure therapy (ET) has been observed to be an effective modality for the treatment of combat-related posttraumatic stress disorder (PTSD). Recently, efforts have been made to use virtual reality (VR) to enhance outcome with modes of ET. How such therapy applies to service members who are facing the reality of a combat deployment has been unknown. This case series documents the first use of VR-based therapy to the treatment of PTSD in a combat theater. Results of therapy are reported from a mental health clinic in Camp Fallujah, Iraq. Combat PTSD constituted a relatively small percentage of overall mental health patients seen. Those who did present with PTSD were offered VR-based ET or traditional ET. Patients who received either treatment modality showed significant gains, and no service member in treatment had to be medically evacuated because of ongoing PTSD symptoms. This demonstrates that ET, with or without the use of VR, can be an effective means of helping service members with mental health issues while they serve in theater.

    Taking advantage of the microgravity environment of space NASA has initiated the preliminary design of a permanently manned space station that will support technological advances in process science and stimulate the development of new and improved materials having applications across the commercial spectrum. Previous studies have been performed to define from the researcher's perspective, the requirements for laboratory equipment to accommodate microgravity experiments on the space station. Functional requirements for the identified experimental apparatus and support equipment were determined. From these hardware requirements, several items were selected for concept designs and subsequent formulation of development plans. This report documents the concept designs and development plans for two items of experiment apparatus - the Combustion Tunnel and the Advanced Modular Furnace, and two items of support equipment the Laser Diagnostic System and the Integrated Electronics Laboratory. For each concept design, key technology developments were identified that are required to enable or enhance the development of the respective hardware.

    There is a lack of research on perceived health effects of electronic cigarettes by adult users. Because more people are choosing electronic cigarettes (e-cigarettes) in addition to, or instead of traditional cigarettes, it is important for the nurse practitioner (NP) to understand why. A comprehensive literature search was conducted using four scholarly databases. The search strategy utilized remained consistent. Qualitative, quantitative, observational studies and meta-analyses were considered for review. Of the 52 articles preliminarily retrieved, 9 met inclusion criteria and were analyzed. The majority of e-cigarette users perceive they are less harmful to health than traditional cigarettes. One reason for use is smoking cessation. Current guidelines recommend against promoting e-cigarette use. More research is needed on the long-term health effects of e-cigarettes as well as regulatory statements to guide future healthcare practice. As prevalence of e-cigarette use increases, it is important for NPs to understand the perceived effects on health by adults who use them and, specifically, how these perceptions motivate use. Armed with this information, the NP can communicate with patients about e-cigarettes, confidently recommend against their use, and begin discussions about reliable smoking cessation tools and resources that will help patients achieve their goals. ©2016 American Association of Nurse Practitioners.

    Objectives: The purpose of the Health Sciences Library System (HSLS) electronic book (e-book) study was to assess use, and factors affecting use, of e-books by all patron groups of an academic health sciences library serving both university and health system–affiliated patrons. Methods: A web-based survey was distributed to a random sample (n = 5,292) of holders of library remote access passwords. A total of 871 completed and 108 partially completed surveys were received, for an approximate response rate of 16.5%–18.5%, with all user groups represented. Descriptive and chi-square analysis was done using SPSS 17. Results: Library e-books were used by 55.4% of respondents. Use by role varied: 21.3% of faculty reported having assigned all or part of an e-book for class readings, while 86% of interns, residents, and fellows reported using an e-book to support clinical care. Respondents preferred print for textbooks and manuals and electronic format for research protocols, pharmaceutical, and reference books, but indicated high flexibility about format choice. They rated printing and saving e-book content as more important than annotation, highlighting, and bookmarking features. Conclusions: Respondents' willingness to use alternate formats, if convenient, suggests that libraries can selectively reduce title duplication between print and e-books and still support library user information needs, especially if publishers provide features that users want. Marketing and user education may increase use of e-book collections. PMID:21753914

    Polymer electronics is the science behind many important new developments in technology, such as the flexible electronic display (e-ink) and many new developments in transistor technology. Solar cells, light-emitting diodes, and transistors are all areas where plastic electronics is likely to, or is already having, a serious impact on our daily lives. With polymer transistors and light-emitting diodes now being commercialised, there is a clear need for a pedagogic text thatdiscusses the subject in a clear and concise fashion suitable for senior undergraduate and graduate students.

  14. Experimental Investigation of Space Radiation Processing in Lunar Soil Ilmenite: Combining Perspectives from Surface Science and Transmission Electron Microscopy

    Energetic ions mostly from the solar wind play a major role in lunar space weathering because they contribute structural and chemical changes to the space-exposed surfaces of lunar regolith grains. In mature mare soils, ilmenite (FeTiO3) grains in the finest size fraction have been shown in transmission electron microscope (TEM) studies to exhibit key differences in their response to space radiation processing relative to silicates [1,2,3]. In ilmenite, solar ion radiation alters host grain outer margins to produce 10-100 nm thick layers that are microstructurally complex, but dominantly crystalline compared to the amorphous radiation-processed rims on silicates [1,2,3]. Spatially well-resolved analytical TEM measurements also show nm-scale compositional and chemical state changes in these layers [1,3]. These include shifts in Fe/Ti ratio from strong surface Fe-enrichment (Fe/Ti >> 1), to Fe depletion (Fe/Ti < 1) at 40-50 nm below the grain surface [1,3]. These compositional changes are not observed in the radiation-processed rims on silicates [4]. Several mechanism(s) to explain the overall relations in the ilmenite grain rims by radiation processing and/or additional space weathering processes were proposed by [1], and remain under current consideration [3]. A key issue has concerned the ability of ion radiation processing alone to produce some of the deeper- penetrating compositional changes. In order to provide some experimental constraints on these questions, we have performed a combined X-ray photoelectron spectroscopy (XPS) and field-emission scanning transmission electron (FE-STEM) study of experimentally ion-irradiated ilmenite. A key feature of this work is the combination of analytical techniques sensitive to changes in the irradiated samples at depth scales going from the immediate surface (approx.5 nm; XPS), to deeper in the grain interior (5-100 nm; FE-STEM).

Databases were cited as the most effective way to locate relevant information (63.1%; PubMed was the most heavily used database (73.7%, although Medline (via EBSCO, Science Direct, and Academic Search Premier were also used.Respondents were asked how they preferred to obtain online research skills (e.g., on their own, via a colleague, via a librarian, or in some other way. The linked data does not answer this question, however, and instead supplies figures on what types of sessions respondents had attended in the past (44.4% attended library instruction sessions, while others were self-taught, consulted colleagues, attended seminars, or obtained skills through their PhD research.Conclusion – Strong public interest in nutritional issues is a growing trend in the Western world. For those faculty members and scholars researching and teaching on nutrition and related areas, more work on their information needs is required. This study begins to address that gap and found that nutrition, food science, and dietetics faculty share strong similarities with researchers in medicine and the other basic sciences with regard to information needs and behaviours. The focus is on electronic journals, PubMed/Medline, and online access to resources. Important insights include the fact that print journals are still in modest use, researchers use grey literature (e.g., government sources and other non-traditional formats (e.g., conference proceedings and electronic mail lists as information sources, and training sessions need to be offered in a variety of formats in order to address individual preferences.

    Widespread use of medical records for research, without consent, attracts little scrutiny compared to biospecimen research, where concerns about genomic privacy prompted recent federal proposals to mandate consent. This paper explores an important consequence of the proliferation of electronic health records (EHRs) in this permissive atmosphere: with the advent of clinical gene sequencing, EHR-based secondary research poses genetic privacy risks akin to those of biospecimen research, yet regulators still permit researchers to call gene sequence data 'de-identified', removing such data from the protection of the federal Privacy Rule and federal human subjects regulations. Medical centers and other providers seeking to offer genomic 'personalized medicine' now confront the problem of governing the secondary use of clinical genomic data as privacy risks escalate. We argue that regulators should no longer permit HIPAA-covered entities to treat dense genomic data as de-identified health information. Even with this step, the Privacy Rule would still permit disclosure of clinical genomic data for research, without consent, under a data use agreement, so we also urge that providers give patients specific notice before disclosing clinical genomic data for research, permitting (where possible) some degree of choice and control. To aid providers who offer clinical gene sequencing, we suggest both general approaches and specific actions to reconcile patients' rights and interests with genomic research.

    2010-09-01

    The harmful effects of noise exposure during leisure-time activities are beginning to receive some scrutiny. We conducted a preliminary study to investigate the noise levels during the showings of 25 different films. During each screening, various sound measurements were made with a dosimeter. The movies were classified on the basis of both their Motion Picture Association of America (MPAA) rating and their genre, and the size of the theater and the size of the audience were taken into consideration in the final analysis. Our findings suggest that the sound levels of many movies might be harmful to hearing, although we can draw no definitive conclusions. We did not discern any relationship between noise levels and either MPAA rating or genre. Further studies are recommended.

  19. S-TEAMS: A Truly Multiprofessional Course Focusing on Nontechnical Skills to Improve Patient Safety in the Operating Theater.

    Stewart-Parker, Emma; Galloway, Robert; Vig, Stella

    Possessing adequate nontechnical skills (NTS) in operating theaters is of increasing interest to health care professionals, yet these are rarely formally taught. Teams make human errors despite technical expertise and knowledge, compromising patient safety. We designed a 1-day, multiprofessional, multidisciplinary course to teach, practice, and apply these skills through simulation. The course, "S-TEAMS," comprised a morning of lectures, case studies, and interactive teamworking exercises. The afternoon divided the group into multiprofessional teams to rotate around simulated scenarios. During the scenarios, teams were encouraged to focus on NTS, including communication strategies, situational awareness, and prompts such as checklists. A thorough debrief with experienced clinician observers followed. Data was collected through self-assessments, immediate and 6-month feedback to assess whether skills continued to be used and their effect on safety. In total, 68 health care professionals have completed the course thus far. All participants felt the course had a clear structure and that learning objectives were explicit. Overall, 95% felt the scenarios had good or excellent relevance to clinical practice. Self-assessments revealed a 55% increase in confidence for "speaking up" in difficult situations. Long-term data revealed 97% of the participants continued to use the skills, with 88% feeling the course had prevented them from making errors. Moreover, 94% felt the course had directly improved patient safety. There is a real demand and enthusiasm for developing NTS within the modern theater team. The simple and easily reproducible format of S-TEAMS is sustainable and inclusive, and crucially, the skills taught continue to be used in long term to improve patient safety and teamworking.

    Full Text Available O presente artigo discute as possibilidades da inserção do teatro na educação profissional em saúde, tendo como referência a proposta estética e pedagógica de Augusto Boal. A concepção de politecnia, ao defender para a formação dos trabalhadores uma integração entre trabalho, ciência e cultura, abre espaço para novas possibilidades nesse campo. Autores como Paulo Freire, na educação, e Augusto Boal, no teatro, convergem para a perspectiva de construção, por parte dos trabalhadores, de uma cultura e estética próprias, que reflitam sua concepção de mundo. Buscamos pensar de que forma as proposições teatrais de Augusto Boal podem ser apropriadas para o campo da educação em saúde, tentando estabelecer afinidades e relações entre essas duas práticas, dentro da ótica de uma educação para os trabalhadores da saúde que lhes propicie uma formação humana para além daquela requerida de forma mais imediatista pelo mercado de trabalho.This article discusses the possibilities of including the performing arts in professional health education based on the aesthetic and pedagogical proposal set forth by Augusto Boal. The polytechnic concept, by advocating that workers' training include an integration of work, science and culture, opens space for new possibilities in this field. Authors such as Paulo Freire, in the field of education, and Augusto Boal, in theater, converge towards the prospect of the workers building both a culture and aesthetics of their own to reflect their world view. Our goal was to think about how Augusto Boal's theatrical propositions may be appropriate for the field of health education in an attempt to establish relationships and affinities between these two practices, from the perspective of health worker education, that they will provide the professionals with a more humanistic type of training that will extend beyond the labor market's more immediate requirements.

    Full Text Available O objetivo deste artigo é promover uma discussão sobre psicologia e teatro, buscando compreender algumas relações e efeitos possíveis quando ambos se aproximam e se voltam para a produção de subjetividade nas comunidades populares. Um conceito central é o de partilha do sensível, formulado por Jacques Rancière. O texto discute as formas que a partilha do sensível configura tanto no teatro quanto na psicologia comunitária quando estes se propõem a ser vetores da transformação social, e aponta entraves quando estes se limitam à representação convencional dos conflitos sociais. Outro aspecto considerado é a necessidade de dar mais relevo aos processos de produção de desejo na comunidade.This essay aims to discuss psychology and theater, their relations and possible effects when they are both involved with the production of subjectivity in popular communities. One main concept is the distribution of the sensible, created by Jacques Rancière. The text analyses the distribution of the sensible performed by the theater and by community psychology when they search social transformation. This study's conclusions indicate that the persistence of the conventional representation of the social conflicts constitutes an obstacle shared by psychology and theater, and point to the necessity of giving more relevance to the production of desire in the community.

    To provide the advanced interventional procedure of zygapophysial joint neurotomy to soldiers meeting the diagnostic criteria in a combat environment and thus reduce medical evacuations of soldiers from a theater of war. Retrospective chart review was performed on three consecutive soldiers who received neuroablation of the lumbar ZP joint. Patients received single MBB with 1 cc of 1% lidocaine at the b/l L3-L5 levels considered diagnostic if >50% analgesia was achieved concordant with duration of anesthetic.   All procedures were co-performed by the two authors at the Ibn Sina hospital in Baghdad, Iraq over a 3-month period. Three consecutive patients with >50% pain relief from diagnostic medial branch blocks were treated with radiofrequency ablation of the bilateral L3-L4 medial branch nerves and L5 posterior primary ramus. Sensory test stimulation at 50 Hz and motor stimulation at 2 Hz were performed at each level. The nerves were then lesioned at 80° Centigrade for 90 seconds after injection of lidocaine and methylprednisolone. Procedure was considered successful if patients were able to wear body armour without significant discomfort (at least 1 hour/day). Medical evacuation from Iraq was prevented and all soldiers returned to rigorous combat duties including the wearing of body armour daily. We believe to be the first to report on the use of RF nerve ablation in a war time setting and with this functional outcome. Wiley Periodicals, Inc.

    As part of ongoing climate science education initiatives, the Science Museum of Virginia hosted Creative Change in March 2017. The event featured multidisciplinary programming created by scientists, artists, and students reacting to and interpreting climate change and resiliency through a variety of artistic mediums and informal science education. Creative Change was developed in consideration of studies conducted at Columbia University that indicate traditional educational approaches, which rely heavily on scientific information and data literacy, fail to engage and inspire action in a majority of people. Our informal science education programming developed for Creative Change, by contrast, is inclusive to all ages and backgrounds, integrating scientific data and an artistic human touch. Our goal was to increase public awareness of climate change and resiliency through the humanities in support of the Museum's mission to inspire Virginians to enrich their lives through science. Visitors were invited to attend Coral Reef Fever, a dance performance of coral bleaching; high school and university art exhibitions; climate data performed by a string quartet; poetry, rap, and theater performances; and a panel discussion by artists and scientists on communicating science through the arts and humanities. Based on 26 post- event survey results, we found as a result that visitors enjoyed the event (mean of 9.58 out of 10), learned new information (9.07), and strongly agreed that the arts and humanities should be used more in communicating science concepts (9.77).

  16. Theaters of time and space: The American planetarium community, 1930-1970

    Science.gov (United States)

    Marche, Jordan Dale, II

    American astronomy education was transformed by the introduction of a remarkable teaching tool---the projection planetarium. Conceived at the Carl Zeiss firm of Jena, Germany, the first prototype was exhibited at the Deutsches Museum, Munich, in 1923. Between 1930 and 1970, more than 700 planetaria were completed or remained under construction in the Unite States, Canada, and Mexico. Members of the American planetarium community united to form the first continent-wide professional association and to launch its quarterly journal, signifying that disciplinary maturity had been achieved. Social developments in the American planetarium community are examined in light of three principal issues (along with the role of gender): patronage, professionalization, and popularization. The analytical narrative is supplemented by quantitative analysis of North American planetaria and their personnel. Utilizing methods employed in collective biography, the Appendix contains further assessments derived from five professional traits of the community's 919 known planetarium directors. On the basis of technological developments and the changing nature of patronage, three distinct periods of historical development are recognized. In the formative stage (1930--1946), the community was dominated by Zeiss-equipped facilities installed at five metropolitan cities. During the second period (1947--1957), inexpensive pinhole-style projectors, marketed by Philadelphia entrepreneur Armand N. Spitz, revolutionized the availability of 'artificial skies'. In response to the "crisis of confidence" triggered by Sputnik's launch, a third developmental period (1958--1970) ensued. The necessity of offering a space science education to rapidly growing numbers of young people justified the construction of hundreds of new planetaria through the 1960s. Originally created for teaching the confirmation of scientific theories, planetaria became important tools for researching other biological and educational

  18. Theater of Memory against a Background of Stars: A Generation Starship Concept between Fiction and Reality

    Caroti, Simone

    2009-03-01

    The concept of the generation starship constitutes a feasible response to the serious travel-time restrictions that the light-speed limit imposes upon human exploration of deep space-``feasible'' in the sense that it could be realized within a reasonably short time span, given our present state of technological advancement. It was Tsiolkovsky, the Russian pioneer of space flight, who first conceptualized the generation starship. In his 1928 paper, The Future of Earth and Mankind, Tsiolkovsky imagines the creation of a fleet of ``Noah's Arks,'' self-sufficient, man-made worldlets that would travel to a distant star system over a period of hundreds or thousands of years, while the crew onboard simply live out their lives maintaining and piloting the ships, and have children whom they teach the necessary skills to do the same once they are gone. Their distant descendants, tens or hundreds of generations in the future, will complete the voyage when the ships finally arrive at their appointed destination. Since Tsiolkovsky's time, science and science fiction have leapfrogged each other in an attempt to imagine what the conditions and consequences of such a venture could be. For example: how could one maintain a stable society throughout such a long period of time-and what sort of governing body should operate during the voyage? How would the composition and number of the crew influence the danger of genetic drift or decay? How might the ship-born generations retain their commitment to the goals of the culture(s) that first built and then equipped the ship back on Earth, when Earth itself has become less than a memory to them? How will space change them, both biologically and psychologically? Is it possible to imaginatively explore the impact of imponderable, unexpected factors-a shipboard emergency, a previously unobserved physical phenomenon, a paradigm-changing discovery? This paper explores the evolution of the generation starship concept between 1940 and 1970, and

    2013-03-01

    Recent advances in the creation and modulation of graphenelike systems are introducing a science of ``designer Dirac materials.'' In its original definition, artificial graphene is a man-made nanostructure that consists of identical potential wells (quantum dots) arranged in an adjustable honeycomb lattice in the two-dimensional electron gas. As our ability to control the quality of artificial graphene samples improves, so grows the need for an accurate theory of its electronic properties, including the effects of electron-electron interactions. Here we determine those effects on the band structure and on the emergence of Dirac points, and discuss future investigations and challenges in this field.

    The University of Nebraska at Omaha has been a state leader in helping Nebraska teachers embrace earth systems science education, with a special emphasis in online coursework. UNO was one of the initial members in the Earth Systems Science Education Alliance (ESSEA) and has offered three different ESSEA courses, with a total of 167 students having taken ESSEA courses at UNO for graduate credit. UNO is currently involved in expanding its earth system science courses, modules, and educational research. We are also integrating these courses into several degree programs, including a Masters of Science in Education, a new Middle School Endorsement, a Certificate in Urban Education, and the Graduate Program for the Department of Geography/Geology. UNO is beginning to examine teacher content learning and science reasoning within its coursework. Feedback surveys from earlier ESSEA offerings already indicate a strongly positive perception of the courses by the teachers enrolled in the coursework. Project impact has been documented in teacher projects, quotes, and lessons associated with the coursework activities. We will describe the UNO earth system science efforts (emphasizing ESSEA coursework), and describe past efforts and teacher perceptions, as well as new strategies being undertaken to more closely examine content learning and science reasoning impact with course participants. We will also describe online course modules being developed within the UNO online course efforts, including one on the global amphibian crisis, and also the impact of urbanization on a local native prairie environment.

  5. Assessment of preventive measures for accidental blood exposure in operating theaters: a survey of 20 hospitals in Northern France.

    Accidental exposures to blood of body fluids (ABE) expose health care workers (HCW) to the risk of occupational infection. Our aim was to assess the prevention equipment available in the operating theater (OT) with reference to guidelines or recommendations and its use by the staff in that OT on that day and past history of ABE. Correspondents of the Centre de Coordination de la Lutte contre les Infections Nosocomiales (CCLIN) Paris-Nord ABE Surveillance Taskforce carried out an observational multicenter survey in 20 volunteer French hospitals. In total, 260 operating staff (including 151 surgeons) were investigated. Forty-nine of the 260 (18.8%) staff said they double-gloved for all patients and procedures, changing gloves hourly. Blunt-tipped suture needles were available in 49.1% of OT; 42 of 76 (55.3%) of the surgeons in these OT said they never used them. Overall, 60% and 64% of surgeons had never self-tested for HIV and hepatitis C virus (HCV), respectively. Fifty-five surgeons said they had sustained a total of 96 needlestick injuries during the month preceding the survey. Ten of these surgeons had notified of 1 needlestick injury each to the occupational health department of their hospital (notification rate, 10.4%). The occurrence of needlestick injury remained high in operating personnel in France in 2000. Although hospitals may improve access to protective devices, operating staff mindful of safety in the OT should increase their use of available devices, their knowledge of their own serostatus, and their ABE notification rate to guide well-targeted prevention efforts.

    Simulation has been used as a learning tool in different disciplines and professions, including medicine and its specialties. Its usefulness is directly related to the integration of objectives, contents, methodologies and specific resources in each area of knowledge. To describe the development of an educational experience implemented in the Pontificia Universidad Javeriana Cali (Cali, Colombia) with medical students of Human Behavior II program, between 2012 and 2013. This experience was performed with simulated patients played by actors of the Altergesto theater group, that were interviewed by students under the supervision of psychiatrists and teachers of the subject, using the Simulated Hospital of the University. A historical development recall of the teaching sequence was made from the first half of 2012 to the second half of 2013, a statement of pedagogical objectives, and a description of the teaching-learning strategies. 158 interviews were conducted over a period of two years during which it was necessary to raise methodological solutions to adapt this teaching sequence to the content and objectives of the subject. The high-fidelity simulation, integrating actors who represent psychiatric patients mixed with the technology of a Simulated Hospital was useful to achieve compliance with the objectives proposed in the course of Human Behavior II, as a part of the program of Medicine at the Pontificia Universidad Javeriana Cali. In parallel, the construction of experience as an interdisciplinary project and the practical approach of this strategy may impact on cognitive, emotional, behavioral dimensions of the participants, encouraging meaningful learning. An easy access database for the collected material and the study of the effects of this strategy in the formation of long-term students is needed.

    Full Text Available Cet article a pour ambition d’interroger le rapport du public à une salle de cinéma précise, au cœur du parc Disneyland Paris à Marne-La-Vallée. Cette salle projette à nouveau depuis juin 2010 l’attraction Captain Eo, film de science-fiction en 3D relief réalisé par Francis Ford Coppola en 1986, avec Michael Jackson dans le rôle-titre. Remplacé depuis 1998 par une autre attraction, Captain Eo fait son retour un an après le décès de la star, et implique dès lors un rapport très particulier à son public, par son statut d’hommage post-mortem. Il s’agira de comprendre la façon dont l’attraction structure son public, et la façon dont celui-ci peut construire à son tour le sens du film qu’il est en train de voir. C’est donc une approche sémio-pragmatique que nous convoquons ici, en nous référant à Roger Odin, afin d’envisager, à partir du film lui-même et de son mode de diffusion, ce que l’attraction Captain Eo révèle théoriquement du lien entre le spectateur et l’image d’une star comme Michael Jackson, qui plus est un an après son décès. Il s’agira de comprendre de quelle manière le film de Coppola ainsi que son contexte de diffusion – le parc d’attraction Disneyland Paris – permettent de penser ou d’interroger un type de pratique spectatorielle différent de celles engendrées par d'autres salles de cinéma.This article tries to question the link between the public and a precise movie theater, in Disneyland Paris Marne-La-Vallée, proposing again since june 2010 the attraction Captain Eo, science-fiction 3D movie by Francis Ford Coppola in 1986, starring Michael Jackson.

    Science field trips can positively impact and motivate students. However, if a field trip is not executed properly, with appropriate preparation and follow-up reinforcement, it can result in a loss of valuable educational time and promote misconceptions in the students. This study was undertaken to determine if a classroom lesson before an out-of-the-classroom activity would affect learner gain more or less than a lesson after the activity. The study was based on the immersive theater movie ``Earth's Wild Ride'' coupled with a teacher-led Power Point lesson. The participants in the study were students in a sixth grade physical science class. The order of lessons showed no detectable effect on final learner outcomes. Based on pre- and post-testing, improvement in mean learning gain came from the teacher-led lesson independent of the movie. The visit to the immersive theater, however, had significant positive effects that did not show up in the quantitative results of the testing.

    Key-words: Polar science, Earth science, Theatre, Hands on activities The legendary Antarctic Expedition of sir E. Shackleton and his crew of 27 aboard the Endurance (1914/16) trapped in the Antarctic ice has become the starting point to learn about Polar Science and Climate Change. While the students were involved into this incredible adventure by the astonishing images of the Australian photographer Frank Hurley (who joined the crew), they discovered the world in which this story happened. Students were then involved in hands-on activities and role plays and have become the writers of the play "Uomini a scienza ai confini del mondo". They act the story of Shackelton's expedition and they tell at the same time to the audience about ice pack, ice cores and their role in understanding the past of the climate, physical and geographical characteristic of polar regions, thermal phenomena related to adaptations of polar animals, solar radiation at different latitude, day/night duration. The theater was the place to "stage" some scientific experiments and to explain the current research carried out in polar regions and their importance in climate change studies and to stress some similarities between Antarctica and space. The project was carried out from teachers of science, letters and geography and was born in collaboration with the "Piccolo Teatro di Milano" and the association "Science Under 18" with the support of a professional actor and director and was played for other schools at "EXPO 2015" in Milano (Italy). In our opinion drama activities improve reading comprehension, and both verbal and non-verbal communication skills. To be able to write and to act, students need a deep understanding of contents. Arts, including theatre, are a good key to involve emotionally students. To have an audience different from their own teachers and classmates offers a real task and the opportunity to play and let grow real skills.

    2013-05-01

    Science Enterprises are problems that students genuinely want to solve, questions that students genuinely want to answer, that naturally entail reading, writing, investigation, and discussion. Engaging students in personally-relevant science enterprises provides both a diagnostic opportunity and a context for providing students the comprehensible input they need. We can differentiate instruction by creating science enterprise zones that are set up for the incremental increase in challenge for the students. Comprehensible input makes reachable, those just-out-of-reach concepts in the mix of the familiar and the new. EcoVoices takes students on field research expeditions within an urban natural area, the San Gabriel River Discovery Center. This project engages students in science enterprises focused on understanding ecosystems, ecosystem services, and the dynamics of climate change. A sister program, EcoVoces, has been launched in Mexico, in collaboration with the Universidad Loyola del Pacífico. 1) The ED3U Science Inquiry Model, a learning cycle model that accounts for conceptual change: Explore { Diagnose, Design, Discuss } Use. 2) The ¿NQUIRY Wheel, a compass of scientific inquiry strategies; 3) Inquiry Science Expeditions, a way of laying out a science learning environment, emulating a field and lab research collaboratory; 4) The Science Educative Experience Scale, a diagnostic measure of the quality of the science learning experience; and 5) Mimedia de la Ciencia, participatory enactment of science concepts using techniques of mime and improvisational theater. BACKGROUND: Science has become a vehicle for teaching reading, writing, and other communication skills, across the curriculum. This new emphasis creates renewed motivation for Scientists and Science Educators to work collaboratively to explore the common ground between acquiring science understanding and language acquisition theory. Language Acquisition is an informal process that occurs in the midst of

To answer, we discuss data science from three perspectives: statistical, computational, and human. Although each of the three is a critical component of data science, we argue that the effective combination of all three components is the essence of what data science is about.

    shape maximizes strength and is not a direct consequence of sapping. Infrequent flash floods of ~1-10 m3/s (woody debris and erosion indicated depth) exceed the magnitude of 1-2 L/s spring discharges by more than three orders of magnitude, and flooding is primarily responsible for sediment transport, particularly imbricated rocks up to tens of cm in size. The tributary canyons are growing headward along their contributing streams rather than up the structural dip, except where the contributing plateau surface is a dip slope (e.g., Fence and Explorer canyons). Few headwalls and contributing streams follow a large exposed tectonic joint; any structural control is primarily due to cumulative smaller fractures. These observations suggest a hybrid model for theater-headed valleys in massive rocks. Seepage weathering is an essential factor in forming steep headwalls and alcoves in Navajo sandstone, but headward retreat and erosion of debris depends on flash floods rather than seepage erosion. Plateau topography, contributing streams, and small joints rather than structural dip or large tectonic fractures control the valley planform.

    Due to Iran's growing need for accelerators in various applications, IPM's electron Linac project has been defined. This accelerator is a 15 MeV energy S-band traveling-wave accelerator which is being designed and constructed based on the klystron that has been built in Iran. Based on the design, operating mode is π /2 and the accelerating chamber consists of two 60cm long tubes with constant impedance and a 30cm long buncher. Amongst all construction methods, shrinking method is selected for construction of IPM's electron Linac tube because it has a simple procedure and there is no need for large vacuum or hydrogen furnaces. In this paper, different aspects of this method are investigated. According to the calculations, linear ratio of frequency alteration to radius change is 787.8 MHz/cm, and the maximum deformation at the tube wall where disks and the tube make contact is 2.7μ m. Applying shrinking method for construction of 8- and 24-cavity tubes results in satisfactory frequency and quality factor. Average deviations of cavities frequency of 8- and 24-cavity tubes to the design values are 0.68 MHz and 1.8 MHz respectively before tune and 0.2 MHz and 0.4 MHz after tune. Accelerating tubes, buncher, and high power couplers of IPM's electron linac are constructed using shrinking method.

  5. Virtual reflections in electronic acoustic architecture

    van Munster, Bjorn

    2005-09-01

    In the era of the ancient Greeks and Byzantines, the first attempts for increasing reverberation time are noted. In the 1950s, the Ambiophonic system accomplished this by means of an electronic device, for the first time. The early systems only increased the reverberation time by delaying the picked-up reverberation. With the introduction of multichannel feedback-based systems, the reverberation level also could be increased. Later, it was understood that it was important to also fill in the missing reflections, address reflection density, frequency dependence, etc. This resulted in the development of the SIAP concept. Current DSP technology led to the development of a processor whereby density, length, level, and the frequency content can be controlled for different areas in the same room or different rooms, leading to the concept of the acoustic server. electronic acoustic architecture has become the current state-of-the-art approach for solving acoustic deficiencies in, among others, rehearsal rooms, theaters, churches, and multipurpose venues. Incorporation of complementary passive acoustic solutions provides an optimum solution for all room problems. This paper discusses the utilization of virtual reflections in the new approach of electronic acoustic architecture for different environments. Measurements performed in the Sejong Performing Arts Centre, Seoul, South Korea, show the power of this approach.

  6. Adults' decision-making about the electronic waste issue: The role of the nature of science conceptualizations and moral concerns in socio-scientific decision-making

    Science.gov (United States)

    Yu, Yuqing

    Socio-scientific issues have become increasingly important in Science-Technology-Society (STS) education as a means to make science learning more relevant to students' lives. This study used the e-waste issue as a context to investigate two aspects of socio-scientific decision-making: (1) the relationship between the nature of science (NOS) conceptualizations and decision-making; and (2) moral concerns involved in the process of decision-making. This study contributes to the field of socio-scientific issue research and STS education in the following ways. First, it is the first study that performed meta-analysis to seek the relationship between the NOS understanding and decision-making. This study concludes that valuable NOS conceptualizations that are highly related to the socio-scientific issue under investigation, rather than general NOS understanding, exert statistically significant influences on decision-making. Second, this study empirically examined the Multiple Responses Model (MRM), which enables the transfer of qualitative NOS responses into quantitative data, and hence, inferential statistics. The current study justifies the significance of unidimensionality to the application of the MRM. It addresses the limitations associated with the MRM and provides implications for future use of the MRM in other contexts. Finally, the study explores the role of moral concerns in socio-scientific decision-making. Eight participants engaged in interviews that were designed to elicit their reactions and feelings regarding the issue of exporting e-waste to poor countries. Qualitative analyses demonstrated that moral considerations were significant influences on decision-making. In addition, participants' action responses revealed that they were motivated to take action to help the environment. The study has implications for socio-scientific issue studies in other contexts and for teacher education programs that use socio-scientific issues to advance teachers' reasoning

    Hard material technologies were surveyed to establish the hard electronic technology which offers superior characteristics under hard operational or environmental conditions as compared with conventional Si devices. The following technologies were separately surveyed: (1) The device and integration technologies of wide gap hard semiconductors such as SiC, diamond and nitride, (2) The technology of hard semiconductor devices for vacuum micro- electronics technology, and (3) The technology of hard new material devices for oxides. The formation technology of oxide thin films made remarkable progress after discovery of oxide superconductor materials, resulting in development of an atomic layer growth method and mist deposition method. This leading research is expected to solve such issues difficult to be easily realized by current Si technology as high-power, high-frequency and low-loss devices in power electronics, high temperature-proof and radiation-proof devices in ultimate electronics, and high-speed and dense- integrated devices in information electronics. 432 refs., 136 figs., 15 tabs.

    Full Text Available It is found that the vacuum triode, transistor, monolithic circuit and microprocessor were the most important inventions of traditional electronics. Thus, the origins of the traditional electronics should be associated with the invention of the vacuum triode, but not with the invention of vacuum diode. It is shown that the science of electronics is not as young as computer science or up-to-date information technologies: electronics, including active electronics, had already celebrated the centenary, and the period of 2004–2008 is the period of numerous already solid jubilees. Thus, the terminology of electronics is not at initial stage of evolution as well – general terms should be already systematized and normalized. However, Lithuanian terms for electronic devices invented before tens of years and terms for old-defined notions associated with these devices are still varying, some are worsened. Especially, the incorrectly motivated terms used for variations of transistors and microcircuits are analyzed in the article. It is motivated which terms are preferable, systematic and exact. The paper is dedicated to the 50th anniversary of monolithic circuit, as well as the 60th anniversary of transistor, the 40th jubilee of microprocessor and centenary of electronics.

  17. An examination of intrinsic errors in electronic structure methods using the Environmental Molecular Sciences Laboratory computational results database and the Gaussian-2 set

    International Nuclear Information System (INIS)

    Feller, D.; Peterson, K.A.

    1998-01-01

    The Gaussian-2 (G2) collection of atoms and molecules has been studied with Hartree endash Fock and correlated levels of theory, ranging from second-order perturbation theory to coupled cluster theory with noniterative inclusion of triple excitations. By exploiting the systematic convergence properties of the correlation consistent family of basis sets, complete basis set limits were estimated for a large number of the G2 energetic properties. Deviations with respect to experimentally derived energy differences corresponding to rigid molecules were obtained for 15 basis set/method combinations, as well as the estimated complete basis set limit. The latter values are necessary for establishing the intrinsic error for each method. In order to perform this analysis, the information generated in the present study was combined with the results of many previous benchmark studies in an electronic database, where it is available for use by other software tools. Such tools can assist users of electronic structure codes in making appropriate basis set and method choices that will increase the likelihood of achieving their accuracy goals without wasteful expenditures of computer resources. copyright 1998 American Institute of Physics

    A system capable of performing radiography using a beam of electrons. Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

A palavra 'ciência' deve ser compreendida aqui em sentido amplo, englobando não apenas as ciências naturais, mas também as ciências humanas, assim como a palavra 'tecnologia' deve ser associada à ciência aplicada. Arte e ciência serão entendidas como processos criativos, como formas de representação do mundo e expressão do conhecimento humano.The article offers some reflections on the main interactions between theater, science, and technology down through the history of theater. Based on our experience at "Science in the Spotlight", part of the Casa de Oswaldo Cruz's Museum of Life, we discuss how these interactions can be part of a science museum's daily activities. We use the word 'science' in its broad sense, encompassing not only the natural but human sciences as well; likewise, we use the word 'technology' as it relates to applied science. Art and science are understood here as creative processes, as ways of representing the world and expressing human knowledge.

    A series of calcium phosphate standards having calcium/phosphorus (Ca/P) molar ratios of 0.50, 1.00, 1.50, and 1.67, respectively, was prepared for bulk specimen analysis using scanning electron microscopy (SEM) and energy-dispersive X-ray microanalysis (EDXA). The standards were mounted on carbon planchettes as either pure crystals or crystals embedded in epoxy resin. Ten different samples of each embedded and non-embedded standard were analyzed in a JEOL 100 CX electron microscope interfaced with a Kevex 8000 EDXA system using a lithium-drifted silicon detector and a multichannel analyzer. The Ca/P ratios were determined by calculating both net peak intensities without matrix corrections and atomic kappa-ratios using the MAGIC V computer program with ZAF correction factors for quantitative analysis. There was such extensive absorption of phosphorus X-rays in standards embedded in an epoxy matrix that the observed Ca/P ratios were statistically compatible with four different standards ranging in theoretical Ca/P ratios from 1.0 to 1.67. Although the non-embedded crystals showed a greater separation in the Ca/P ratios, both methods of preparation produced serious flaws in analysis. Direct application of the discovery of this caveat to the identification of suspected bone fragments for forensic science purposes is discussed

    Identifying fundamental drivers of science and developing predictive models to capture its evolution are instrumental for the design of policies that can improve the scientific enterprise-for example, through enhanced career paths for scientists, better performance evaluation for organizations hosting research, discovery of novel effective funding vehicles, and even identification of promising regions along the scientific frontier. The science of science uses large-scale data on the production of science to search for universal and domain-specific patterns. Here, we review recent developments in this transdisciplinary field.

Close to the condensed matter side, properties and functions might still very well be scalable, whereas close to the atomic and molecular side, the scalability is mostly lost. Properties and functions change qualitatively or quantitatively by orders of magnitude when the dimensions become smaller than a critical size in the nanometer range.

    2011-03-01

    Communicating science to the public is the responsibility of all scientists and necessary for an informed electorate and as an inspiration to young minds. Yet successful national strategies for communicating science and the venues for such communication seem limited. Science museums and TV programs like NOVA reach millions of people but still only a very small fraction of the US population. In terms of daily science reporting very few newspapers have a devoted science reporter and it is only the New York Times which has a significant weekly reporting section on science (and health). What can one do about reaching wider and new audiences? We recently ran an NSF sponsored international conference entitled Communicating Science to the Public through the Performing Arts (www.sciartconference2010.com). At the conference there were sessions on science and theater, science and TV and film, science and dance, science and music and science festivals, cafes and events (web.gc.cuny.edu/sciart). Using these new approaches one can reach a new and wider audience and one can also take advantage of the seemingly insatiable interest of the press in the arts. Examples of successful new strategies for communicating science will be presented, evaluated and shown to be replicable at a relatively modest cost of time and money.

    International Nuclear Information System (INIS)

    Gary, S.P.

    1987-01-01

    The electron acoustic wave becomes a normal mode of an unmagnetized collisionless plasma in the presence of two electron components with similar densities, but strongly disparate temperatures. The characteristic frequency of this mode is the plasma frequency of the cooler electron component. If these two electron components have a relative drift speed several times the thermal speed of the cooler component, the electron/electron acoustic instability may arise. This paper describes the parametric dependences of the threshold drift speed and maximum growth rate of this instability, and compares these with the same properties of the electron/ion acoustic instability. Under the condition of zero current, the electron/ion acoustic instability typically has the lower threshold drift speed, so that observation of the electron/electron acoustic instability is a strong indication of the presence of an electrical current in the plasma

    The Afghanistan Surge saw NATO troops working with their Afghan partners to remove Taliban governance and replace it with a more democratic model. As part of this endeavor, medical support for both trauma and humanitarian cases was needed. Identify and discuss disease trends to better prepare for future combat medical treatments. Retrospective review of operative experience from a neurosurgeon from November 2010 to April 2011. 63 cases were performed on 20 NATO and 43 Afghan patients. Combat-related neurotrauma represented 73% (46/63) of cases and humanitarian cases represented the remainder. The most common diseases among humanitarian cases were benign tumors (29%, 5/17), cranioplasty (23%, 4/17), obstructive hydrocephalus (11%, 2/17), nonobstructive hydrocephalus (11%, 2/17), hemifacial spasm (11%, 2/17), and cerebral angiography (11%, 2/17). There was 1 death from ventriculitis for a complication rate of 6%. In select well-nourished, patients with minimal risk of needing tracheostomy, humanitarian neurosurgery can be safely performed in theater with a complication rate (6%) no worse than patients operated on in the United States.

  7. The Cancelled Duel Between R.B. Apollonsky and V.E. Meyerhold: From the History of Russian Theater During the Epoch of Revolution

    Gordeev Petr Nickolaevich

    2015-04-01

    Full Text Available In the beginning of April 1917 a conflict burst out in the troupe of the Alexandrinsky Theatre: a number of prominent actors brought an accusation of aesthetic and political nature against director V.E. Meyerhold. The immediate reason for this was Meyerhold’s act – the director attended the meeting of “theatrical figures” convened by F.A. Golovin, the Commissioner of the Provisional government, not being among the persons elected to participate in the meeting of the troupe. In particular, artist R.B. Apollonsky compared V.E. Meyerhold with a famous friend of Nicholas II – G.E. Rasputin. Therefore, having ignored the accusations in “modernism”, he reacted harshly to the comparison with Rasputin. Outraged by this, Meyerhold called Apollonsky out to a duel. As a result, the duel did not take place, but the story was covered in press in unfriendly to Meyerhold light. The author concludes that Meyerhold represented in press after the February Revolution as a representative of the “old regime”, during this period was trying to distance himself from the fallen monarchy, actively assimilating the radical vocabulary. The isolation of Meyerhold in the circles of theater community took place after the described incident and was likely to make it easier for him in future to join the party of Bolsheviks.

    Applying environmental education in primate range countries is an important long-term activity to stimulate pro-conservation behavior. Within captive settings, mega-charismatic species, such as great apes are often used to increase knowledge and positively influence attitudes of visitors. Here, we evaluate the effectiveness of a short-term video and theater program developed for a Western audience and adapted to rural people living in two villages around Nouabalé-Ndoki National Park, Republic of Congo. We assessed the knowledge gain and attitude change using oral evaluation in the local language (N = 111). Overall pre-program knowledge about Western gorillas (Gorilla gorilla) was high. Detailed multivariate analysis of pre-program knowledge revealed differences in knowledge between two villages and people with different jobs while attitudes largely were similar between groups. The short-term education program was successful in raising knowledge, particularly of those people with less pre-program knowledge. We also noted an overall significant attitude improvement. Our data indicate short-term education programs are useful in quickly raising knowledge as well improving attitudes. Furthermore, education messages need to be clearly adapted to the daily livelihood realities of the audience, and multi-variate analysis can help to identify potential target groups for education programs. © 2017 Wiley Periodicals, Inc.

    Did you know... that the writing on the bathroom wall isn't just graffiti anymore? Studies have shown that messages in unusual locations can have extraordinary impact. A growing number of companies and non-profit organizations are placing signage in unexpected venues, such as bathroom stalls, sporting arena seatbacks, gas stations, and diaper-changing areas. A 2003 study found that public response to promotional materials posted in restrooms was overwhelmingly positive, and respondents view these materials for up to two minutes instead of the 3 to 5 seconds they spend with traditional print marketing. Recall rates of content and messages are high, and researchers found bathroom signage to be 40% more effective than a typical print sign. It is often difficult to design effective education and outreach programs that reach a broader audience than a fairly self-selective one. Most of our events and projects ask audiences to come to us. This format inherently attracts a science-interested audience. So how do you reach the other half, those non-traditional learners, in an effective manner? Take the science to them! Help your message be more effective by "shocking” them with the science. Placing science, technology, engineering, and mathematical (STEM) content in unexpected venues makes it accessible, memorable, and likely to reach a captive audience that might not otherwise seek it out. The "Did You Know?” campaign brings STEM messages to underserved audiences through innovative placement. Bathroom stalls, movie theaters, and shopping malls are visited by thousands each day and provide a surprising and overlooked venue for outreach.

  13. Electronic emission and electron guns

    International Nuclear Information System (INIS)

    Roy, Amitava

    2010-01-01

    This paper reviews the process of electron emission from metal surface. Although electrons move freely in conductors like metals, they normally do not leave the metal without some manipulation. In fact, heating and bombardment are the two primary ways in which electrons are emitted through the use of a heating element behind the cathode (termed thermionic emission) or as a result of bombardment with a beam of electrons, ions, or metastable atoms (termed secondary emission). Another important emission mechanism called Explosive Electron Emission (EEE) is also often used in various High Voltage Pulse Power Systems to generate very high current (few hundreds of kA) pulsed electron beams. The electron gun is the device in that it shoots off a continuous (or pulsed) stream of electrons. A brief idea about the evolution of the electron gun components and their basis of functioning are also discussed. (author)

    The photo shows a close-up of a Lichtenberg figure – popularly called an “electron tree” – produced in a cylinder of polymethyl methacrylate (PMMA). Electron trees are created by irradiating a suitable insulating material, in this case PMMA, with an intense high energy electron beam. Upon discharge......, during dielectric breakdown in the material, the electrons generate branching chains of fractures on leaving the PMMA, producing the tree pattern seen. To be able to create electron trees with a clinical linear accelerator, one needs to access the primary electron beam used for photon treatments. We...... appropriated a linac that was being decommissioned in our department and dismantled the head to circumvent the target and ion chambers.

    Electrons have played a significant role in the development of many fields of physics during the last century. The interest surrounding them mostly involved their wave-like features prescribed by the quantum theory. In particular, these features correctly predict the behaviour of electrons in various physical systems including atoms, molecules, solid-state materials, and even in free space. Ten years ago, new breakthroughs were made, arising from the new ability to bestow orbital angular momentum (OAM) to the wave function of electrons. This quantity, in conjunction with the electron's charge, results in an additional magnetic property. Owing to these features, OAM-carrying, or twisted, electrons can effectively interact with magnetic fields in unprecedented ways and have motivated materials scientists to find new methods for generating twisted electrons and measuring their OAM content. Here, we provide an overview of such techniques along with an introduction to the exciting dynamics of twisted electrons.

    Microfluidics, a field that has been well-established for several decades, has seen extensive applications in the areas of biology, chemistry, and medicine. However, it might be very hard to imagine how such soft microfluidic devices would be used in other areas, such as electronics, in which stiff, solid metals, insulators, and semiconductors have previously dominated. Very recently, things have radically changed. Taking advantage of native properties of microfluidics, advances in microfluidics-based electronics have shown great potential in numerous new appealing applications, e.g. bio-inspired devices, body-worn healthcare and medical sensing systems, and ergonomic units, in which conventional rigid, bulky electronics are facing insurmountable obstacles to fulfil the demand on comfortable user experience. Not only would the birth of microfluidic electronics contribute to both the microfluidics and electronics fields, but it may also shape the future of our daily life. Nevertheless, microfluidic electronics are still at a very early stage, and significant efforts in research and development are needed to advance this emerging field. The intention of this article is to review recent research outcomes in the field of microfluidic electronics, and address current technical challenges and issues. The outlook of future development in microfluidic electronic devices and systems, as well as new fabrication techniques, is also discussed. Moreover, the authors would like to inspire both the microfluidics and electronics communities to further exploit this newly-established field.

    1991-01-01

    The stupendous successes of the Dirac equation and quantum electro-dynamics have established the electron as the best understood of the fundamental constituents of matter. Nevertheless, physicists agree that the electron still has secrets to reveal. Moreover, powerful new theoretical and experimental tools for probing those secrets have been sharpened during the last decade. This workshop was organized to bring theorists and experimentalists together to discuss their common goal of knowing the electron. Present state and future prospects for progress toward that goal are here described. The theoretical papers encompass a wide range of views on the electron. Several argue that the 'Zitter-bewegung' is more than a mathematical peculiarity of the Dirac equation, that it may well be a real physical phenomenon and worthy of serious study, theoretically and experimentally. Besides generating the electron spin and magnetic moment, the 'Zitterbewegung' may be a vital clue to electron structure and self-interaction. Some of the papers employ a radical new formulation of the Dirac theory which reveals a hidden geo-metric structure in the theory that supports a 'Zitterbewegung' inter-pretation. For the last half century the properties of electrons have been probed primarily by scattering experiments at ever higher energies. Recently, however, two powerful new experimental techniques have emerged capable of giving alternative experimental views of the electron. First, techniques for confining single electrons for long term study have led to the most accurate measurements of the electron magnetic moment. Second, the interaction of high intensity laser fields with atoms and electrons have revealed striking new phenomena such as multiphoton ionization. refs.; figs.; tabs

    2005-01-01

    Financial support for this project has led to advances in the science of single-electron phenomena. Our group reported the first observation of the so-called ''Coulomb Staircase'', which was produced by tunneling into ultra-small metal particles. This work showed well-defined tunneling voltage steps of width e/C and height e/RC, demonstrating tunneling quantized on the single-electron level. This work was published in a now well-cited Physical Review Letter. Single-electron physics is now a major sub-field of condensed-matter physics, and fundamental work in the area continues to be conducted by tunneling in ultra-small metal particles. In addition, there are now single-electron transistors that add a controlling gate to modulate the charge on ultra-small photolithographically defined capacitive elements. Single-electron transistors are now at the heart of at least one experimental quantum-computer element, and single-electron transistor pumps may soon be used to define fundamental quantities such as the farad (capacitance) and the ampere (current). Novel computer technology based on single-electron quantum dots is also being developed. In related work, our group played the leading role in the explanation of experimental results observed during the initial phases of tunneling experiments with the high-temperature superconductors. When so-called ''multiple-gap'' tunneling was reported, the phenomenon was correctly identified by our group as single-electron tunneling in small grains in the material. The main focus throughout this project has been to explore single electron phenomena both in traditional tunneling formats of the type metal/insulator/particles/insulator/metal and using scanning tunneling microscopy to probe few-particle systems. This has been done under varying conditions of temperature, applied magnetic field, and with different materials systems. These have included metals, semi-metals, and superconductors. Amongst a number of results, we have

    Conventional electronics has in the past ignored the spin on the electron, however things began to change in 1988 with the discovery of giant magnetoresistance in metallic thin film stacks which led to the development of a new research area, so called spin-electronics. In the last 10 years, spin-electronics has achieved a number of breakthroughs from the point of view of both basic science and application. Materials research has led to several major discoveries: very large tunnel magnetoresistance effects in tunnel junctions with crystalline barriers due to a new spin-filtering mechanism associated with the spin-dependent symmetry of the electron wave functions new magnetic tunnelling barriers leading to spin-dependent tunnelling barrier heights and acting as spin-filters magnetic semiconductors with increasingly high ordering temperature. New phenomena have been predicted and observed: the possibility of acting on the magnetization of a magnetic nanostructure with a spin-polarized current. This effect, due to a transfer of angular momentum between the spin polarized conduction electrons and the local magnetization, can be viewed as the reciprocal of giant or tunnel magnetoresistance. It can be used to switch the magnetization of a magnetic nanostructure or to generate steady magnetic excitations in the system. the possibility of generating and manipulating spin current without charge current by creating non-equilibrium local accumulation of spin up or spin down electrons. The range of applications of spin electronics materials and phenomena is expanding: the first devices based on giant magnetoresistance were the magnetoresistive read-heads for computer disk drives. These heads, introduced in 1998 with current-in plane spin-valves, have evolved towards low resistance tunnel magnetoresistice heads in 2005. Besides magnetic recording technology, these very sensitive magnetoresistive sensors are finding applications in other areas, in particular in biology. magnetic

  4. Exploring Groundwater origin for theater-headed valleys on the walls of Ius Chasma based on geomorphological analogy to the Saharan Plateaus

    Understanding the origin and evolution of Martian fluvial landforms constrains the ambiguities associated to the variability of paleoclimatic and hydrological conditions. Despite of the significance of understanding the mechanism of formation of theater-headed valleys (THV) in Valles Mariners, where abundant distribution of seasonal liquid water flow is reported, their origin remains debatable. The original groundwater sapping hypothesis is challenged by the capability of springs to cut canyons into massive rocks and alternatively mega-floods and landslides were suggested. On Earth however, widespread THV cutting through the carbonate plateaus in the Sahara are confirmed to be of long-lasting groundwater processes based on recent isotopic, geochemical and hydrogeological evidences. Geomorphological characterizations of the THV in both the Sahara and in Valles Marineris suggest similar settings including: (1) widespread and dense occurrence along the length of escarpments, (2) low relief floors, (3) association with extensive faulting, and (4) lack of well-developed stream networks and small upstream contributing areas. The above suggest that both the Martian and the Saharan THV to be of groundwater origins. Herein, we constraint the geomorphological, lithological and textural characteristics of THV in El Diffa and El-Merir plateaus in the Eastern Sahara as a limited analog to the THV in Ius Chasma using structural and textural mapping derived from ALOS PalSAR scenes and similar settings on Mars using SHARAD, MOLA and HIRISE images. These observations are correlated with several in-situ field and laboratory measurements for hardness, granulometry and channel morphology to support the common phenomenology. Preliminary findings show that in both sets of THV, we observe a spatial confinement of boulders to the sidewalls with relatively finer grains along the channel courses, and association with large-scale hydrated sulphates along the sidewalls and channel bottoms

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

    The roots, stems, leaves, and vascular circuitry of higher plants are responsible for conveying the chemical signals that regulate growth and functions. From a certain perspective, these features are analogous to the contacts, interconnections, devices, and wires of discrete and integrated electronic circuits. Although many attempts have been made to augment plant function with electroactive materials, plants’ “circuitry” has never been directly merged with electronics. We report analog and digital organic electronic circuits and devices manufactured in living plants. The four key components of a circuit have been achieved using the xylem, leaves, veins, and signals of the plant as the template and integral part of the circuit elements and functions. With integrated and distributed electronics in plants, one can envisage a range of applications including precision recording and regulation of physiology, energy harvesting from photosynthesis, and alternatives to genetic modification for plant optimization.

    Electronic voting technology is a two edged sword. It comes with many risks but brings also many benefits. Instead of flat out rejecting the technology as uncontrollably dangerous, we advocate in this paper a different technological angle that renders electronic elections trustworthy beyond...... the usual levels of doubt. We exploit the trust that voters currently have into the democratic process and model our techniques around that observation accordingly. In particular, we propose a technique of trace emitting computations to record the individual steps of an electronic voting machine...... for a posteriori validation on an acceptably small trusted computing base. Our technology enables us to prove that an electronic elections preserves the voter’s intent, assuming that the voting machine and the trace verifier are independent....

    The combination of printing technology with manufacturing electronic devices enables a new paradigm of printable electronics, where 'smart' functionality can be readily incorporated into almost any product at low cost. Over recent decades, rapid progress has been made in this field, which is now emerging into the industrial andcommercial realm. However, successful development and commercialisation on a large scale presents some significant technical challenges. For fully-printable electronic systems, all the component parts must be deposited from solutions (inks), requiring the development of new inorganic, organic and hybrid materials.A variety of traditional printing techniques are being explored and adapted forprinting these new materials in ways that result in the best performing electronicdevices. Whilst printed electronics research has initially focused on traditional typesof electronic device such as light-emitting diodes, transistors, and photovoltaics, it is increasingly apparent that a much wider range of applications can be realised. The soft and stretchable nature of printable materials makes them perfect candidates forbioelectronics, resulting in a wealth of research looking at biocompatible printable inks and biosensors. Regardless of application, the properties of printed electronicmaterials depend on the chemical structures, processing conditions, device architecture,and operational conditions, the complex inter-relationships of which aredriving ongoing research. We focus on three particular 'hot topics', where attention is currently focused: novel materials, characterisation techniques, and device stability. With progress advancing very rapidly, printed electronics is expected to grow over the next decade into a key technology with an enormous economic and social impact.

    2009-01-01

    The use of diamond for advanced applications has been the dream of mankind for centuries. Until recently this dream has been realized only in the use of diamond for gemstones and abrasive applications where tons of diamonds are used on an annual basis. Diamond is the material system of choice for many applications, but its use has historically been limited due to the small size, high cost, and inconsistent (and typically poor) quality of available diamond materials until recently. The recent development of high quality, single crystal diamond crystal growth via the Chemical Vapor Deposition (CVD) process has allowed physcists and increasingly scientists in the life science area to think beyond these limitations and envision how diamond may be used in advanced applications ranging from quantum computing, to power generation and molecular imaging, and eventually even diamond nano-bots. Because of diamond's unique properties as a bio-compatible material, better understanding of diamond's quantum effects and a convergence of mass production, semiconductor-like fabrication process, diamond now promises a unique and powerful key to the realization of the bio-electronic devices being envisioned for the new era of medical science. The combination of robust in-the-body diamond based sensors, coupled with smart bio-functionalized diamond devices may lead to diamond being the platform of choice for bio-electronics. This generation of diamond based bio-electronic devices would contribute substantially to ushering in a paradigm shift for medical science, leading to vastly improved patient diagnosis, decrease of drug development costs and risks, and improved effectiveness of drug delivery and gene therapy programs through better timed and more customized solutions.

    2014-03-01

    In multiphoton photoemission electron microscopy (nP-PEEM) electrons are emitted from surfaces at a rate proportional to the surface electromagnetic field amplitude. We use 2P-PEEM to give nanometer scale visualizations of light of diffracted and waveguide fields around various microstructures. We use Fourier analysis to determine the phase and amplitude of surface fields in relation to incident light from the interference patterns. To provide quick and intuitive simulations of surface fields, we employ two dimensional Fresnel-Kirchhoff integration, a technique based on freely propagating waves and Huygens' principle. We find generally good agreement between simulations and experiment. Additionally diffracted wave simulations exhibit greater phase accuracy, indicating that these waves are well represented by a two dimensional approximation.

  6. Quantum Hall Electron Nematics

    Science.gov (United States)

    MacDonald, Allan

    In 2D electron systems hosted by crystals with hexagonal symmetry, electron nematic phases with spontaneously broken C3 symmetry are expected to occur in the quantum Hall regime when triplets of Landau levels associated with three different Fermi surface pockets are partially filled. The broken symmetry state is driven by intravalley Coulombic exchange interactions that favor spontaneously polarized valley occupations. I will discuss three different examples of 2D electron systems in which this type of broken symmetry state is expected to occur: i) the SnTe (111) surface, ii) the Bi (111) surface. and iii) unbalanced bilayer graphene. This type of quantum Hall electron nematic state has so far been confirmed only in the Bi (111) case, in which the anisotropic quasiparticle wavefunctions of the broken symmetry state were directly imaged. In the SnTe case the nematic state phase boundary is controlled by a competition between intravalley Coulomb interactions and intervalley scattering processes that increase in relative strength with magnetic field. An in-plane Zeeman field alters the phase diagram by lifting the three-fold Landau level degeneracy, yielding a ground state energy with 2 π/3 periodicity as a function of Zeeman-field orientation angle. I will comment on the possibility of observing similar states in the absence of a magnetic field. Supported by DOE Division of Materials Sciences and Engineering Grant DE-FG03-02ER45958.

    2017-12-01

    Full Text Available The research scenario on science teaching in early education indicates emerging issues on the pedagogical practices developed educational level. Furthermore, although the importance of teaching science since the beginning of basic education, there is still residual and limited space of this discipline in the early years of schooling to be recognized. Allied to this complex picture, school practices has performed largely with emphasis on lectures, with reduced participation of students in their learning process. So, some investigations have been developed with the intention to subsidize the construction of pedagogical practices based on specific childhood learning of scientific concepts. Thus, the present study, theoretical in nature, aimed at discussing the main strengths of playful perspective to the work of the multidisciplinary teacher, with possible situations to be held in the school context and to contribute to children's learning in an atmosphere that encourages increasingly interest and curiosity. The literature review indicated several alternatives, and, for this text, were selected: the didactic games, the works of children's literature and theater. The analysis of the use of these resources has concluded that the ludic perspective, when planned and developed in a wise manner, may represent a key element of the teaching process that favors learning qualitatively students.

  9. Science and Improv: Saying "YES" to Creative Collaboration and Scintillating Communication

    Science.gov (United States)

    Wong, G. J.

    2015-12-01

    Communicating research results to a non-specialist audience can be challenging. Strategies that work well in lab group meetings, such as using acronyms and jargon, may fall flat with 7th graders or Congressional staffers. Empowering real-world audiences with our stories helps raise awareness and inform decision-making, whether it's related to family food purchases or national policy. Ideally, we scientists, engineers and researchers directly connect with our audiences, responding spontaneously and actively, distilling our messages into conversational morsels that resonate with them. One tool that I have found useful is deeply rooted in the "tao" of improvisational theater. Why improv? Improv is dancing as if no one is watching, baking from scratch, and playing jazz flute. Improv is Iron Chef, MacGyver with a license to thrill, or the game-winning play. Research is inspired improvisation. And improv can teach us a lot about how to play, how to feel comfortable and present even while flailing, and how to truly listen. Effective science communicators listen. In fact, therein lies the power of "yes …", a building block of improvisational theater. "Yes …" is both collaborative ("yes, and …") and innovative ("yes, because …"), and investment in an attitude of saying "yes …" demonstrates an intent to listen. Improv is not any one specific thing so much as a process by which we do things. Skills that strengthen communication, such as spontaneity, authenticity and connectivity, are honed through philosophies inherent in improv. This presentation highlights improv-based activities that enhance science communication with purpose, vividness, and emotion.

    "Breaking the fourth wall" is a theater convention where the narrator or character speaks directly to the audience. As an Assistant Editor-in-Chief, as I comment on a recent basic science study investigating rotator cuff repair, I break the fourth wall and articulate areas of basic science research excellence that align with the vision that we hold for our journal. Inclusion of a powerful video strengthens the submission. We prefer to publish clinical videos in our companion journal, Arthroscopy Techniques, and encourage basic science video submissions to Arthroscopy. Basic science research requires step-by-tedious-step analogous to climbing a mountain. Establishment of a murine rotator cuff repair model was rigorous and research intensive, biomechanically, radiographically, histologically, and genetically documented, a huge step toward the bone-to-tendon healing research summit. This research results in a model for both rotator cuff repair and the pinnacle of quality, basic science research. Copyright © 2018 Arthroscopy Association of North America.

    Bioresorbable electronics is a new type of electronics technology that can potentially lead to biodegradable and dissolvable electronic devices to replace current built-to-last circuits predominantly used in implantable devices and consumer electronics. Such devices dissolve in an aqueous environment in time periods from seconds to months, and generate biological safe products. This paper reviews materials, fabrication techniques, and applications of bioresorbable electronics, and aims to inspire more revolutionary bioresorbable systems that can generate broader social and economic impact. Existing challenges and potential solutions in developing bioresorbable electronics have also been presented to arouse more joint research efforts in this field to build systematic technology framework.
