Breakthrough Propulsion Physics Project: Project Management Methods

Science.gov (United States)

Millis, Marc G.

2004-01-01

To leap past the limitations of existing propulsion, the NASA Breakthrough Propulsion Physics (BPP) Project seeks further advancements in physics from which new propulsion methods can eventually be derived. Three visionary breakthroughs are sought: (1) propulsion that requires no propellant, (2) propulsion that circumvents existing speed limits, and (3) breakthrough methods of energy production to power such devices. Because these propulsion goals are presumably far from fruition, a special emphasis is to identify credible research that will make measurable progress toward these goals in the near-term. The management techniques to address this challenge are presented, with a special emphasis on the process used to review, prioritize, and select research tasks. This selection process includes these key features: (a) research tasks are constrained to only address the immediate unknowns, curious effects or critical issues, (b) reliability of assertions is more important than the implications of the assertions, which includes the practice where the reviewers judge credibility rather than feasibility, and (c) total scores are obtained by multiplying the criteria scores rather than by adding. Lessons learned and revisions planned are discussed.

Revisiting the physics education projects in a Bakhitinian perspective

Directory of Open Access Journals (Sweden)

José Ortega

2017-12-01

Full Text Available In this article, we point out correlations between the 1970s social-historical context and the of physics teaching sphere at the time, through the analysis of utterances expressed in two educational projects texts: The Physics Project at Harvard University and the Project of Physical Education at the University of Sao Paulo. Given the infinity and complexity of mediations between society and projects, we focus on mediations that refer to the broader spheres of social activity. We want to outline the socio-historical mediations that allow us to identify the social and historical limits to which they were submitted. Therefore, it is in this dialectical relationship between educational work and the historical horizon of a society that we take the bakhtinian concept of discursive genre, which allows representing the relations between history and discourse. Within this relationship social teleology, communicative intentions and the discursive choices of the subjects of human activity are established. Thus our discursive, social, and historical perspective of analysis indicates that the educational discourses they produced, is an expression of the needs, values and commitments of organized social groups of those societies, and that their ideological productions were reflected and refracted in the thematic content, composition and genre style produced within the teaching in that context.

1986-01-01

The Tennessee Valley Authority (TVA) is actively involved in decommissioning a uranium mill located near the town of Edgemont, South Dakota. The Edgemont Mill Decommissioning Project, which is unique in many respects, will involve dismantlement of the old inactive mill building and excavation and transportation of several million tons of uranium mill tailings to a permanent disposal site. To ensure that workers are adequately protected from radiation exposure during decommissioning operations, a health physics program appropriate for the decommissioning situation was developed. The Edgemont Mill Decommissioning Project Health Physics Manual (HPM) gives the programmatic requirements for worker radiation protection. The requirements of the HPM are implemented by means of detailed onsite operating procedures. The Edgemont project health physics program was developed using currently available regulations and guidance for an operating uranium mill with appropriate modifications for decommissioning. This paper discusses the development, implementation, and documentation of that program

The "Finding Physics" Project: Recognizing and Exploring Physics Outside the Classroom

Science.gov (United States)

Beck, Judith; Perkins, James

2016-11-01

Students in introductory physics classes often have difficulty recognizing the relevance of physics concepts outside the confines of the physics classroom, lab, and textbook. Even though textbooks and instructors often provide examples of physics applications from a wide array of areas, students have difficulty relating physics to their own lives. Encouraging students to apply physics to their own surroundings helps them develop the critical analysis skills of a scientifically literate and competent citizen. Fink, in his book Creating Significant Learning Experiences, emphasizes the importance of constructing opportunities to help students connect what they learn in their academic courses with past and current life experiences and link them to possible future life experiences. Several excellent papers in this journal have presented labs and activities that address this concern by encouraging teachers to bring real-world examples into the classroom or to take students into the field for data collection and observation. Alternatively, Smith suggests a writing exercise in which his students identify and explain an event in terms of their understanding of physics. In this paper we present a multiphase exercise that challenges students to find their own examples of physics from outside the classroom and analyze them using the conceptual understanding and quantitative skills which they are developing in the classroom. The ultimate goal of the "Finding Physics" project is to improve students' learning through enhancing their recognition that, to quote one participant's end-of-course survey, "Physics is everywhere!"

A project for space observations of solar flares for the coming solar maximum phase is briefly described. The main objective is to make a comprehensive study of high energy phenomena of flares through simultaneous imagings in both hard and soft X-rays. The project will be performed with collaboration from US scientists. The HESP (High Energy Solar Physics) WG of ISAS (Institute of Space and Astronautical Sciences) has extensively discussed future aspects of space observations of high energy phenomena of solar flares based on successful results of the Hinotori mission, and proposed a comprehensive research program for the next solar maximum, called the HESP (SOLAR-A) project. The objective of the HESP project is to make a comprehensive study of both high energy phenomena of flares and quiet structures including pre-flare states, which have been left uncovered by SMM and Hinotori. For such a study simultaneous imagings with better resolutions in space and time in a wide range of energy will be extremely important.

A project-based course about outreach in a physics curriculum

Science.gov (United States)

Bobroff, Julien; Bouquet, Frédéric

2016-07-01

We describe an undergraduate course where physics students are asked to conceive an outreach project of their own. This project-based-learning course alternates between the project conception and teaching activities about outreach. It ends in a public show. Students decide the topic and format on their own. An analysis of the students’ productions over three years shows that all physics fields were equally covered, and various formats were used (experimental devices, animation or fiction movies, games, live events, photography). Some typical examples are described. We also analyse the benefits of this approach from the students’ perspective, through a survey done over three classes. Students showed an overall very good assessment of the course (average of 4.5(0.6) on an appreciation scale from 1 to 5) and recognised having developed outreach skills but also project-management and group-work know-how. They acknowledged this course to be a unique opportunity to share with an audience their interest in physics compared to other courses. They further mentioned that it served as an intermission in a classical academic curriculum. They also point out some challenges, especially the time-consuming issue. This survey together with the practical description of the course implementation should help other universities develop similar courses.

1987-01-01

The Shippingport Atomic Power Station consists of the nuclear steam supply system and associated radioactive waste processing systems, which are owned by the United States Department of Energy, and the turbine-generator and balance of plant, which is owned by the Duquesne Light Company. The station is located at Shippingport, Pennsylvania on seven acres of land leased by DOE from Duquesne Light Company. The Shippingport Station Decommissioning Project is being performed under contract to the DOE by the General Electric Company and its integrated subcontractor, Morrison-Knudsen Company. as the Decommissioning Operations Contractor. This paper describes the current status of the physical decommissioning work, which started September 1985. The preparations required to start a major decommissioning work effort in a safe and cost effective manner are discussed including the development and implementation of a cost/schedule control system. The detailed plan required to ensure that people, property, and procedures are ready in sufficient time to support the start of physical decommissioning is also discussed. The total estimated cost of the Shippingport Station Decommissioning Project should be $98.3 M, with the Project scheduled for completion in April 1990. As the decommissioning of the first commercial-scale nuclear power plant, the Shippingport Project is expected to set the standard for safe, cost-effective demolition of nuclear plants

Terms - project, projecting and the method of projecting - are nowadays frequently used in different relations. Those terms, especially as methods (of a cognitive process), are also transferred to the educational process. Before a new educational method comes to practice, the teacher should be familiar with it and preferably when it is done so during his university studies. An optional subject called Physics in a system of science subjects has been included into physics curricula for students of the fourth year of their studies at the Faculty of Science of Constantine the Philosopher University in Nitra. Its task is to make students aware of ways how to coordinate knowledge and instructions presented in these subjects through analysis of curricula and textbooks. As a part of their seminars students are asked to create integrated tasks and experiments which can be assessed from the point of view of either physics or chemistry or biology and which can motivate pupils and form their complex view on various phenomena in the nature. Therefore the article discusses theoretical and also practical questions related to experience that originates from placing the mentioned method and the subject Physics in a system of science subjects into the preparation of a natural sciences teacher in our workplace.

Moscow State University physics alumni and the Soviet Atomic Project

International Nuclear Information System (INIS)

Kiselev, Gennadii V

2005-01-01

In this paper, two closely related themes are addressed: (1) the role that M V Lomonosov Moscow State University (MSU) played in training specialists in physics for the Soviet Atomic Project, and (2) what its alumni contributed to the development of thermonuclear weapons. In its earlier stages, the Soviet Atomic Project was in acute need of qualified personnel, without whom building nuclear and thermonuclear weapons would be an impossible task, and MSU became a key higher educational institution grappled with the training problem. The first part of the paper discusses the efforts of the leading Soviet scientists and leaders of FMD (First Main Directorate) to organize the training of specialists in nuclear physics at the MSU Physics Department and, on the other hand, to create a new Physics and Technology Department at the university. As a result, a number of Soviet Government's resolutions were prepared and issued, part of which are presented in the paper and give an idea of the large-scale challenges this sphere of education was facing at the time. Information is presented for the first time on the early MSU Physics Department graduates in the structure of matter, being employed in the FMD organizations and enterprises from 1948 to 1951. The second part discusses the contribution to the development of thermonuclear weapons by the teams of scientists led by Academicians I E Tamm, A N Tikhonov, and I M Frank, and including MSU physics alumni. The paper will be useful to anyone interested in the history of Russian physics. (from the history of physics)

Oakley, Christopher

2016-03-01

Research suggests that students benefit from peer interaction and active engagement in the classroom. The quality, nature, effect of these interactions is currently being explored by Physics Education Researchers. Spelman College offers an introductory physics sequence that addresses content and research skills by engaging students in open-ended research projects, a form of Project-Based Learning. Students have been surveyed at regular intervals during the second semester of trigonometry-based course to determine the frequency of interactions in and out of class. These interactions can be with current or past students, tutors, and instructors. This line of inquiry focuses on metrics of Social Network analysis, such as centrality of participants as well as segmentation of groups. Further research will refine and highlight deeper questions regarding student performance in this pedagogy and course sequence.

Kinoshita, F.M. Pipkin, K. Strauch, R. Wilson, and H. Yamamoto. Professor G.J. Feldman currently serves as chair of this committee. Dr. Brandenburg is the Director of the High Energy Physics Laboratory and administers the DOE high energy physics contract. In the fall of 1991 S. Mishra will join this committee. Harvard is planning to make one or two additional senior faculty appointments in experimental high energy physics over the next two years. The principal goals of the work described here are to carry out forefront programs in high energy physics research and to provide first rate educational opportunities for students. The experimental program supported through HEPL is carried out at the major accelerator centers in the world and addresses some of the most important questions in high energy physics. Harvard's educational efforts are concentrated in graduate education, where they are currently supporting thirteen research students. In addition, undergraduate students work in projects at HEPL during the academic year and over summers. These budget projections cover all of the Harvard based high energy physics experimental activities. The open-quotes umbrellaclose quotes nature of this contract greatly simplifies support of essential central technical and computer services and helps the group to take advantage of new physics opportunities and to respond to unexpected needs. The funding for the operation of the HEPL facility is shared proportionally by the experimental groups. Harvard financially supports this high energy physics research program in many ways

Health human resources continue to emerge as a critical health policy issue across the United States. The purpose of this study was to develop a strategy for modeling future workforce projections to serve as a basis for analyzing annual supply of and demand for physical therapists across the United States into 2020. A traditional stock-and-flow methodology or model was developed and populated with publicly available data to produce estimates of supply and demand for physical therapists by 2020. Supply was determined by adding the estimated number of physical therapists and the approximation of new graduates to the number of physical therapists who immigrated, minus US graduates who never passed the licensure examination, and an estimated attrition rate in any given year. Demand was determined by using projected US population with health care insurance multiplied by a demand ratio in any given year. The difference between projected supply and demand represented a shortage or surplus of physical therapists. Three separate projection models were developed based on best available data in the years 2011, 2012, and 2013, respectively. Based on these projections, demand for physical therapists in the United States outstrips supply under most assumptions. Workforce projection methodology research is based on assumptions using imperfect data; therefore, the results must be interpreted in terms of overall trends rather than as precise actuarial data-generated absolute numbers from specified forecasting. Outcomes of this projection study provide a foundation for discussion and debate regarding the most effective and efficient ways to influence supply-side variables so as to position physical therapists to meet current and future population demand. Attrition rates or permanent exits out of the profession can have important supply-side effects and appear to have an effect on predicting future shortage or surplus of physical therapists. © 2016 American Physical Therapy

2010-03-15

This poster describes the Fast Physics Testbed for the new FAst-physics System Testbed and Research (FASTER) project. The overall objective is to provide a convenient and comprehensive platform for fast turn-around model evaluation against ARM observations and to facilitate development of parameterizations for cloud-related fast processes represented in global climate models. The testbed features three major components: a single column model (SCM) testbed, an NWP-Testbed, and high-resolution modeling (HRM). The web-based SCM-Testbed features multiple SCMs from major climate modeling centers and aims to maximize the potential of SCM approach to enhance and accelerate the evaluation and improvement of fast physics parameterizations through continuous evaluation of existing and evolving models against historical as well as new/improved ARM and other complementary measurements. The NWP-Testbed aims to capitalize on the large pool of operational numerical weather prediction products. Continuous evaluations of NWP forecasts against observations at ARM sites are carried out to systematically identify the biases and skills of physical parameterizations under all weather conditions. The highresolution modeling (HRM) activities aim to simulate the fast processes at high resolution to aid in the understanding of the fast processes and their parameterizations. A four-tier HRM framework is established to augment the SCM- and NWP-Testbeds towards eventual improvement of the parameterizations.

Analysis model for the physical dimension in the environmental studies of electric transmission projects

2001-01-01

This study makes a description and analysis of the physical aspects of the environment, which are contemplated, in the environmental studies of the projects of high voltage for electric transmission lines. Its meaning and out reach are defined in this projects, in its different phases of implementation; that is in the stages of design, construction and operation, making proposals to improve the adequate incorporation of physical dimension in the environmental activities. A very important aspect, worked out in the investigation, has to do with the way as this dimension is described in the real terms of reference for EIA of the Ministry of Environment; that is why it is analysed and some elements are proposed which are to correct and to articulate properly the information in these studies, because some problems were found in the articulation and contents of the physical aspects in the studies of environmental impact (EIA). Another very important aspect, which was obtained with this research, is the methodological proposal for the integration of the components of the physical dimension in which s ynthesis units are defined in different scales for the integration of those components. These facts will facilitate a better understanding of the natural processes in the areas of influence of the projects and a better understanding of the reciprocal relations between the project and the physical surroundings. In the process of searching a methodology for integration of the components of the physical dimension it is hoped that the studies be more congruent from the environmental point of view

Abe Pacini, A.; Tegbaru, D.; Max, A., Sr.

2017-12-01

We present here the concept and state-of-art of the new space physics youth education and outreach initiative called "Girls InSpace project". The project goal is to spread quality scientific information to underrepresented groups, motivate girls in STEM and promote gender equality in the Space Physics area. Initially, the "Girls InSpace project" will be available in two languages (Portuguese and English) aiming to reach out to the youth of Brazil, United States, Nigeria, South Africa, Ethiopia and Angola. Eventually, the material will be translated to French and Spanish, focusing on French-speaking countries in Africa and Latin America. The project spans a collection of four books about a group of young girls and their adventures (always related to the sky and simultaneously introducing earth and space science concepts). Ancillary content such as a webpage, mobile applications and lesson plans are also in development. The books were written by a Space Physicist PhD woman, illustrated by a Brazilian young artist and commented by senior female scientists, creating positive role models for the next generation of girls in STEM. The story lines were drawn around the selected topics of astronomy and space physics, introducing scientific information to the target readers (girls from 8-13 years old) and enhancing their curiosity and critical thinking. The books instill the readers to explore the available extra web-content (with images, videos, interviews with scientists, real space data, coding and deeper scientific information) and game apps (with Virtual Reality components and real space images). Moreover, for teachers K-12, a collection of lesson plans will be made available, aiming to facilitate scientific content discussed in the books and inside classroom environments. Gender bias in STEM reported earlier this year in Nature and based on a study of the American Geophysical Union's member database showed a competitive disadvantage for women in the Earth and Space

The SuperB Project: Status and the Physics Reach

The SuperB experiment is a next generation Super Flavour Factory expected to accumulate 75 ab −1 of data at the Υ(4S) in five years of nominal running, and will be built at the recently established Cabibbo Laboratory on the outskirts of Rome. In addition to running data at the Υ(4S), SuperB will be able to accumulate data from the ψ(3770) up to the Υ(6S). A polarized electron beam enables unique physics opportunities at SuperB. The large samples of B, D and τ decays that will be recorded at SuperB can be used to provide both stringent constraints on new physics scenarios, and over-constraints on the Standard Model. We present the status of the project as well as the physics potential of SuperB.

This sample management plan provides guidelines for sectioning, preparation, acceptance criteria, analytical path, and end-of-life disposal for the fuel element segments utilized in the Global Threat Reduction Initiative (GTRI), Fuel Thermo-Physical Characterization Project. The Fuel Thermo-Physical Characterization Project is tasked with analysis of irradiated Low Enriched Uranium (LEU) Molybdenum (U-Mo) fuel element samples to support the GTRI conversion program. Sample analysis may include optical microscopy (OM), scanning electron microscopy (SEM) fuel-surface interface analysis, gas pycnometry (density) measurements, laser flash analysis (LFA), differential scanning calorimetry (DSC), thermogravimetry and differential thermal analysis with mass spectroscopy (TG /DTA-MS), Inductively Coupled Plasma Spectrophotometry (ICP), alpha spectroscopy, and Thermal Ionization Mass Spectroscopy (TIMS). The project will utilize existing Radiochemical Processing Laboratory (RPL) operating, technical, and administrative procedures for sample receipt, processing, and analyses. Test instructions (TIs), which are documents used to provide specific details regarding the implementation of an existing RPL approved technical or operational procedure, will also be used to communicate to staff project specific parameters requested by the Principal Investigator (PI). TIs will be developed, reviewed, and issued in accordance with the latest revision of the RPL-PLN-700, RPL Operations Plan. Additionally, the PI must approve all project test instructions and red-line changes to test instructions.

Evolving Understanding of Antarctic Ice-Sheet Physics and Ambiguity in Probabilistic Sea-Level Projections

Mechanisms such as ice-shelf hydrofracturing and ice-cliff collapse may rapidly increase discharge from marine-based ice sheets. Here, we link a probabilistic framework for sea-level projections to a small ensemble of Antarctic ice-sheet (AIS) simulations incorporating these physical processes to explore their influence on global-mean sea-level (GMSL) and relative sea-level (RSL). We compare the new projections to past results using expert assessment and structured expert elicitation about AIS changes. Under high greenhouse gas emissions (Representative Concentration Pathway [RCP] 8.5), median projected 21st century GMSL rise increases from 79 to 146 cm. Without protective measures, revised median RSL projections would by 2100 submerge land currently home to 153 million people, an increase of 44 million. The use of a physical model, rather than simple parameterizations assuming constant acceleration of ice loss, increases forcing sensitivity: overlap between the central 90% of simulations for 2100 for RCP 8.5 (93-243 cm) and RCP 2.6 (26-98 cm) is minimal. By 2300, the gap between median GMSL estimates for RCP 8.5 and RCP 2.6 reaches >10 m, with median RSL projections for RCP 8.5 jeopardizing land now occupied by 950 million people (versus 167 million for RCP 2.6). The minimal correlation between the contribution of AIS to GMSL by 2050 and that in 2100 and beyond implies current sea-level observations cannot exclude future extreme outcomes. The sensitivity of post-2050 projections to deeply uncertain physics highlights the need for robust decision and adaptive management frameworks.

Information Theoretic Characterization of Physical Theories with Projective State Space

Science.gov (United States)

Zaopo, Marco

2015-08-01

Probabilistic theories are a natural framework to investigate the foundations of quantum theory and possible alternative or deeper theories. In a generic probabilistic theory, states of a physical system are represented as vectors of outcomes probabilities and state spaces are convex cones. In this picture the physics of a given theory is related to the geometric shape of the cone of states. In quantum theory, for instance, the shape of the cone of states corresponds to a projective space over complex numbers. In this paper we investigate geometric constraints on the state space of a generic theory imposed by the following information theoretic requirements: every non completely mixed state of a system is perfectly distinguishable from some other state in a single shot measurement; information capacity of physical systems is conserved under making mixtures of states. These assumptions guarantee that a generic physical system satisfies a natural principle asserting that the more a state of the system is mixed the less information can be stored in the system using that state as logical value. We show that all theories satisfying the above assumptions are such that the shape of their cones of states is that of a projective space over a generic field of numbers. Remarkably, these theories constitute generalizations of quantum theory where superposition principle holds with coefficients pertaining to a generic field of numbers in place of complex numbers. If the field of numbers is trivial and contains only one element we obtain classical theory. This result tells that superposition principle is quite common among probabilistic theories while its absence gives evidence of either classical theory or an implausible theory.

Verification of Electromagnetic Physics Models for Parallel Computing Architectures in the GeantV Project

Amadio, G.; et al.

2017-11-22

An intensive R&D and programming effort is required to accomplish new challenges posed by future experimental high-energy particle physics (HEP) programs. The GeantV project aims to narrow the gap between the performance of the existing HEP detector simulation software and the ideal performance achievable, exploiting latest advances in computing technology. The project has developed a particle detector simulation prototype capable of transporting in parallel particles in complex geometries exploiting instruction level microparallelism (SIMD and SIMT), task-level parallelism (multithreading) and high-level parallelism (MPI), leveraging both the multi-core and the many-core opportunities. We present preliminary verification results concerning the electromagnetic (EM) physics models developed for parallel computing architectures within the GeantV project. In order to exploit the potential of vectorization and accelerators and to make the physics model effectively parallelizable, advanced sampling techniques have been implemented and tested. In this paper we introduce a set of automated statistical tests in order to verify the vectorized models by checking their consistency with the corresponding Geant4 models and to validate them against experimental data.

2007-01-01

Since ICNC 2003, the International Criticality Safety Benchmark Evaluation Project (ICSBEP) has continued to expand its efforts and broaden its scope. Criticality-alarm/shielding type benchmarks and fundamental physics measurements that are relevant to criticality safety applications are not only included in the scope of the project, but benchmark data are also included in the latest version of the handbook. A considerable number of improvements have been made to the searchable database, DICE and the criticality-alarm/shielding benchmarks and fundamental physics measurements have been included in the database. There were 12 countries participating on the ICSBEP in 2003. That number has increased to 18 with recent contributions of data and/or resources from Brazil, Czech Republic, Poland, India, Canada, and China. South Africa, Germany, Argentina, and Australia have been invited to participate. Since ICNC 2003, the contents of the ''International Handbook of Evaluated Criticality Safety Benchmark Experiments'' have increased from 350 evaluations (28,000 pages) containing benchmark specifications for 3070 critical or subcritical configurations to 442 evaluations (over 38,000 pages) containing benchmark specifications for 3957 critical or subcritical configurations, 23 criticality-alarm-placement/shielding configurations with multiple dose points for each, and 20 configurations that have been categorized as fundamental physics measurements that are relevant to criticality safety applications in the 2006 Edition of the ICSBEP Handbook. Approximately 30 new evaluations and 250 additional configurations are expected to be added to the 2007 Edition of the Handbook. Since ICNC 2003, a reactor physics counterpart to the ICSBEP, The International Reactor Physics Experiment Evaluation Project (IRPhEP) was initiated. Beginning in 1999, the IRPhEP was conducted as a pilot activity by the by the Organization of Economic Cooperation and Development (OECD) Nuclear Energy Agency

International Reactor Physics Experiment Evaluation (IRPhE) Project. IRPhE Handbook - 2017 edition

International Nuclear Information System (INIS)

2017-01-01

The International Reactor Physics Evaluation (IRPhE) Project was initiated as a pilot in 1999 by the Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). The project was endorsed as an official activity of the NSC in June 2003. While the NEA co-ordinates and administers the IRPhE Project at the international level, each participating country is responsible for the administration, technical direction and priorities of the project within their respective countries. The information and data included in this handbook are available to NEA member countries, to all contributing countries and to others on a case-by-case basis. The IRPhE Project is patterned after the International Criticality Safety Benchmark Evaluation Project (ICSBEP). It closely co-ordinates with the ICSBEP to avoid duplication of efforts and publication of conflicting information. Some benchmark data are applicable to both nuclear criticality safety and reactor physics technology. Some have already been evaluated and published by the ICSBEP, but have been extended to include other types of measurements in addition to the critical configuration. Through this effort, the IRPhE Project will be able to 1) consolidate and preserve the existing worldwide information base; 2) retrieve lost data; 3) identify areas where more data are needed; 4) draw upon the resources of the international reactor physics community to help fill knowledge gaps; 5) identify discrepancies between calculations and experiments due to deficiencies in reported experimental data, cross-section data, cross-section processing codes and neutronics codes; 6) eliminate a large amount of redundant research and processing of reactor physics experiment data, and 7) improve future experimental planning, execution and reporting. This handbook contains reactor physics benchmark specifications that have been derived from experiments performed at nuclear facilities around the world. The benchmark specifications are intended for use by

Final Report Sustained Spheromak Physics Project FY 1997 - FY 1999

This is the final report on the LDRD SI-funded Sustained Spheromak Physics Project for the years FY1997-FY1999, during which the SSPX spheromak was designed, built, and commissioned for operation at LLNL. The specific LDRD project covered in this report concerns the development, installation, and operation of specialized hardware and diagnostics for use on the SSPX facility in order to study energy confinement in a sustained spheromak plasma configuration. The USDOE Office of Fusion Energy Science funded the construction and routine operation of the SSPX facility. The main distinctive feature of the spheromak is that currents in the plasma itself produce the confining toroidal magnetic field, rather than external coils, which necessarily thread the vacuum vessel. There main objective of the Sustained Spheromak Physics Project was to test whether sufficient energy confinement could be maintained in a spheromak plasma sustained by DC helicity injection. Achieving central electron temperatures of several hundred eV would indicate this. In addition, we set out to determine how the energy confinement scales with T c and to relate the confinement time to the level of internal magnetic turbulence. Energy confinement and its scaling are the central technical issues for the spheromak as a fusion reactor concept. Pending the outcome of energy confinement studies now under way, the spheromak could be the basis for an attractive fusion reactor because of its compact size, simply-connected magnetic geometry, and potential for steady-state current drive

International Reactor Physics Experiment Evaluation (IRPhE) Project

2013-01-01

The International Reactor Physics Experiment Evaluation (IRPhE) Project aims to provide the nuclear community with qualified benchmark data sets by collecting reactor physics experimental data from nuclear facilities, worldwide. More specifically the objectives of the expert group are as follows: - maintaining an inventory of the experiments that have been carried out and documented; - archiving the primary documents and data released in computer-readable form; - promoting the use of the format and methods developed and seek to have them adopted as a standard. For those experiments where interest and priority is expressed by member countries or working parties and executive groups within the NEA provide guidance or co-ordination in: - compiling experiments into a standard international agreed format; - verifying the data, to the extent possible, by reviewing original and subsequently revised documentation, and by consulting with the experimenters or individuals who are familiar with the experimenters or the experimental facility; - analysing and interpreting the experiments with current state-of-the-art methods; - publishing electronically the benchmark evaluations. The expert group will: - identify gaps in data and provide guidance on priorities for future experiments; - involve the young generation (Masters and PhD students and young researchers) to find an effective way of transferring know-how in experimental techniques and analysis methods; - provide a tool for improved exploitation of completed experiments for Generation IV reactors; - coordinate closely its work with other NSC experimental work groups in particular the International Criticality Safety Benchmark Evaluation Project (ICSBEP), the Shielding Integral Benchmark Experiment Data Base (SINBAD) and others, e.g. knowledge preservation in fast reactors of the IAEA, the ANS Joint Benchmark Activities; - keep a close link with the working parties on scientific issues of reactor systems (WPRS), the expert

Developing a project-based computational physics course grounded in expert practice

Burke, Christopher J.; Atherton, Timothy J.

2017-04-01

We describe a project-based computational physics course developed using a backwards course design approach. From an initial competency-based model of problem solving in computational physics, we interviewed faculty who use these tools in their own research to determine indicators of expert practice. From these, a rubric was formulated that enabled us to design a course intended to allow students to learn these skills. We also report an initial implementation of the course and, by having the interviewees regrade student work, show that students acquired many of the expert practices identified.

A research project for introductory physics students, involving an estimate of the surface temperature of the Sun using a parked car, was carried out in the Summer 1995 Research Apprenticeships in Science Program, sponsored by Edison Industrial Systems Center, for local-area high school students. This activity entails both outdoor quantitative observations and theoretical analysis, and yields a result within 12 percent of the accepted value. It was demonstrated that the use of everyday materials and outdoor observations, such as those in this project, is not only educational but also intriguing. The success of this experiment as a summer research project will be discussed.

An interview record with MATSUURA Kiyokata, Professor Emeritus at Nagoya University, is given on the Reacting Plasma Project (R-project), which was proposed and investigated in 1980's by the Institute of Plasma Physics, Nagoya University (IPP Nagoya). The project was planned to aim at producing a DT reacting plasma in tokamak to explore its physics and technology. But after intensive studies on design work, together with some R and D efforts and related investigations, the project could not be realized. The circumstances of the R-Project at its initiation and termination stages are the major topics of the present interview, held as a round-table talk with Prof. Matsuura, the project leader.

The various elements of the Physical/Chemical Closed-Loop Life Support Research Project (P/C CLLS) are described including both those currently funded and those planned for implementation at ARC and other participating NASA field centers. The plan addresses the entire range of regenerative life support for Space Exploration Initiative mission needs, and focuses initially on achieving technology readiness for the Initial Lunar Outpost by 1995-97. Project elements include water reclamation, air revitalization, solid waste management, thermal and systems control, and systems integration. Current analysis estimates that each occupant of a space habitat will require a total of 32 kg/day of supplies to live and operate comfortably, while an ideal P/C CLLS system capable of 100 percent reclamation of air and water, but excluding recycling of solid wastes or foods, will reduce this requirement to 3.4 kg/day.

2016-12-01

Project for Solar-Terrestrial Environment Prediction (PSTEP) is a Japanese nation-wide research collaboration, which was recently launched. PSTEP aims to develop a synergistic interaction between predictive and scientific studies of the solar-terrestrial environment and to establish the basis for next-generation space weather forecasting using the state-of-the-art observation systems and the physics-based models. For this project, we coordinate the four research groups, which develop (1) the integration of space weather forecast system, (2) the physics-based solar storm prediction, (3) the predictive models of magnetosphere and ionosphere dynamics, and (4) the model of solar cycle activity and its impact on climate, respectively. In this project, we will build the coordinated physics-based model to answer the fundamental questions concerning the onset of solar eruptions and the mechanism for radiation belt dynamics in the Earth's magnetosphere. In this paper, we will show the strategy of PSTEP, and discuss about the role and prospect of the physics-based space weather forecasting system being developed by PSTEP.

Family physicians have a key role in the promotion of physical activity, in particular in identifying and counseling persons who have a sedentary lifestyle. Some patients could benefit from intensive individual counseling. Physicians are often not aware of all physical activity promotion activities in the community that they could recommend their patients. In a pilot study, we have tested and adapted the referral of patients from family physicians to specialists in adapted physical activity (APAs). APAs are trained to assess and guide persons towards physical activities adapted to their needs and pathologies and thus towards an increase in physical activity. Pilot data suggest that, while few patients were oriented to the APAs in the pilot project, family physicians appreciate the possibility of collaborating with the APAs.

The ATLAS experiment at the Large Hadron Collider at CERN has a substantial collaborative Education and Outreach project. This article describes its activities and how it promotes physics to students around the world. With the extraordinary possibility to make groundbreaking discoveries, the ATLAS Experiment [1] at the Large Hadron Collider at CERN can play an important role in promoting contemporary physics at school. For many years ATLAS has had a substantial collaborative Education and Outreach (E and O) project in which physicists from various parts of the world take part. When the experiment begins in 2007, students from around the world will be analyzing data using cutting-edge technology. The unprecedented collision energies of the Large Hadron Collider allow ATLAS to decode the 'events' that unfold after the head-on collisions of protons (Fig. 1). The scientific results from these events will reveal much about the basic nature of matter, energy, space, and time. Students and others will be excited as they try to find events that may be signs for dark matter, extra dimensions of space, mini-black holes, string theory, and other fundamental discoveries. Science education and outreach and the promotion of awareness and appreciation of physics research have become important tasks for the research community and should be recognized as a natural and logical part of science research and as an important link between research and society. To be successful these activities have to be done in a systematic and professional way. Leading scientists together with multimedia experts can form a powerful team with teachers and educators in disseminating physics information to school and universities. The ATLAS collaboration has fully recognized the importance of education and outreach. The ATLAS E and O project can be a model for today's large science experiments in promoting science at schools and universities

Students and others will be excited as they try to find events that may be signs for dark matter, extra dimensions of space, mini-black holes, string theory, and other fundamental discoveries. Science education and outreach and the promotion of awareness and appreciation of physics research have become important tasks for the research community and should be recognized as a natural and logical part of science research and as an important link between research and society. To be successful these activities have to be done in a systematic and professional way. Leading scientists together with multimedia experts can form a powerful team with teachers and educators in disseminating physics information to school and universities. The ATLAS collaboration has fully recognized the importance of education and outreach. The ATLAS E&O project can be a model for today's large science experiments in promoting science at schools and universities.

Urban ninth-grade girls interactions with and outcomes from a design-oriented physics project

Higginbotham, Thomas Eric Miksad

Past literature has documented a shrinking but persistent gap in physics and engineering for females, both in school and in the workforce. A commonly recommended strategy to invite girls into science at the school level is to have students work on design-projects in groups, which has been shown to increase all students' learning outcomes and attitudes towards science. Students (n=28) in a ninth-grade inner-city physics class participated in such a project, in which they built remotely operated underwater vehicles (ROV's) over the course of one month. Students (n=23) in a comparison classroom learned the same content using the Active Physics curriculum during the same time frame. Mixed methods were used to study the ROV classroom. Students in both classes were given pre- and post-physics content tests. Qualitative data collected during the project included field notes, video, and teacher interviews. Macro-level data analysis was done, which informed further micro-analysis. Macro-analysis revealed significantly higher learning outcomes for the ROV class than for the non-ROV class. Within the ROV class, girls, and in particular, girls in female-majority groups had increased learning outcomes and high levels of interest and engagement with the project, while girls in mixed-sex and male-majority groups did not. Qualitative macro-analysis revealed that in all of the female-majority groups, females took leadership roles within the groups, while in all of the non female-majority groups, males took leadership roles. The only groups in which girls completely disengaged from the project were mixed-sex or male majority groups. Case studies and cross case analysis suggested that girls foregrounded group process over product, and used the level of group unity as a metric of the groups' success. Groups led by girls were more cooperative and exhibited distributed leadership and participation. These findings were interpreted through lenses of expectation states theory and social

Thorough elucidation of the biological effects of ionizing radiation requires full participation of physical scientists, together with life scientists. Therefore, a key point in the federal research strategy will be to ensure involvement of all physicists actively engaged in radiation research and to recruit more physicists for work in this area. Many new developments in physics, both basic and applied, will occur in dosimetry, spectroscopy, and other physical techniques for studying radiations and their interactions with matter in general. Experiments in radiation biology will be made more precise and accurate in the near future, provided that the outcome of contemporary physical research is to be fully used. Likewise, physics research will continue to provide new kinds of radiation sources and other instrumentation, indispensable for progress in life sciences and their applications. Finally, and most importantly, physical research has provided, and will continue to provide, the soundest possible basis for elucidating detailed mechanisms of molecular and cellular processes that lead to the biological effects of radiation. Even from this point alone, it is amply clear that basic research in radiation physics should be a key element of the federal research strategy

2011-09-01

Since the International Conference on Nuclear Criticality Safety (ICNC) 2007, the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) have continued to expand their efforts and broaden their scope. Eighteen countries participated on the ICSBEP in 2007. Now, there are 20, with recent contributions from Sweden and Argentina. The IRPhEP has also expanded from eight contributing countries in 2007 to 16 in 2011. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Criticality Safety Benchmark Experiments1' have increased from 442 evaluations (38000 pages), containing benchmark specifications for 3955 critical or subcritical configurations to 516 evaluations (nearly 55000 pages), containing benchmark specifications for 4405 critical or subcritical configurations in the 2010 Edition of the ICSBEP Handbook. The contents of the Handbook have also increased from 21 to 24 criticality-alarm-placement/shielding configurations with multiple dose points for each, and from 20 to 200 configurations categorized as fundamental physics measurements relevant to criticality safety applications. Approximately 25 new evaluations and 150 additional configurations are expected to be added to the 2011 edition of the Handbook. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments2' have increased from 16 different experimental series that were performed at 12 different reactor facilities to 53 experimental series that were performed at 30 different reactor facilities in the 2011 edition of the Handbook. Considerable effort has also been made to improve the functionality of the searchable database, DICE (Database for the International Criticality Benchmark Evaluation Project) and verify the accuracy of the data contained therein. DICE will be discussed in separate papers at ICNC 2011. The status of the

Physical activity is a cost-effective and non-pharmaceutical strategy that can help mitigate the physical and psychological health challenges associated with breast cancer survivorship. However, up to 70% of women breast cancer survivors are not meeting minimum recommended physical activity guidelines. Project MOVE is an innovative approach to increase physical activity among breast cancer survivors through the use of Action Grants, a combination of microgrants (small amounts of money awarded to groups of individuals to support a physical activity initiative) and financial incentives. The purpose of this paper is to describe the rationale and protocol of Project MOVE. A quasi-experimental pre-post design will be used. Twelve groups of 8-12 adult women who are breast cancer survivors (N=132) were recruited for the study via face-to-face meetings with breast cancer-related stakeholders, local print and radio media, social media, and pamphlets and posters at community organisations and medical clinics. Each group submitted a microgrant application outlining their proposed physical activity initiative. Successful applicants were determined by a grant review panel and informed of a financial incentive on meeting their physical activity goals. An evaluation of feasibility will be guided by the reach, effectiveness, adoption, implementation, maintenance (RE-AIM) framework and assessed through focus groups, interviews and project-related reports. Physical activity will be assessed through accelerometry and by self-report. Quality of life, motivation to exercise and social connection will also be assessed through self-report. Assessments will occur at baseline, 6 months and 1 year. Ethical approval was obtained from the University of British Columbia's Behavioural Research Ethics Board (#H14-02502) and has been funded by the Canadian Cancer Society Research Institute (project number #702913). Study findings will be disseminated widely through peer-reviewed publications

We present a short overview of the current status of the new accelerator project FAIR at GSI with the new double synchrotron rings and the multi-storage rings. The key features of the new facility, which provides intense relativistic beams of stable and unstable nuclei, are introduced and their relation to the anticipated experimental programs in nuclear structure physics and antiproton physics is shown. The main emphasis in this overview is given to the atomic physics program with unique opportunities which will be provided e.g. by bare U{sup 92+} ions with kinetic energies continuously variable between relativistic energies corresponding to {gamma} up to {approx_equal}35 down to kinetic energies of such ions in traps corresponding to fractions of a Kelvin.

Computer Hardware, Advanced Mathematics and Model Physics pilot project final report

International Nuclear Information System (INIS)

1992-05-01

The Computer Hardware, Advanced Mathematics and Model Physics (CHAMMP) Program was launched in January, 1990. A principal objective of the program has been to utilize the emerging capabilities of massively parallel scientific computers in the challenge of regional scale predictions of decade-to-century climate change. CHAMMP has already demonstrated the feasibility of achieving a 10,000 fold increase in computational throughput for climate modeling in this decade. What we have also recognized, however, is the need for new algorithms and computer software to capitalize on the radically new computing architectures. This report describes the pilot CHAMMP projects at the DOE National Laboratories and the National Center for Atmospheric Research (NCAR). The pilot projects were selected to identify the principal challenges to CHAMMP and to entrain new scientific computing expertise. The success of some of these projects has aided in the definition of the CHAMMP scientific plan. Many of the papers in this report have been or will be submitted for publication in the open literature. Readers are urged to consult with the authors directly for questions or comments about their papers

Bess, John D.; Gullifor, Jim

2015-03-01

The purpose of the International Reactor Physics Experiment Evaluation (IRPhE) Project is to provide an extensively peer-reviewed set of reactor physics-related integral data that can be used by reactor designers and safety analysts to validate the analytical tools used to design next-generation reactors and establish the safety basis for operation of these reactors. This work of the IRPhE Project is formally documented in the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments', a single source of verified and extensively peer-reviewed reactor physics benchmark measurements data. The evaluation process entails the following steps: Identify a comprehensive set of reactor physics experimental measurements data, Evaluate the data and quantify overall uncertainties through various types of sensitivity analysis to the extent possible, verify the data by reviewing original and subsequently revised documentation, and by talking with the experimenters or individuals who are familiar with the experimental facility, Compile the data into a standardized format, Perform calculations of each experiment with standard reactor physics codes where it would add information, Formally document the work into a single source of verified and peer reviewed reactor physics benchmark measurements data. The International Handbook of Evaluated Reactor Physics Benchmark Experiments contains reactor physics benchmark specifications that have been derived from experiments that were performed at nuclear facilities around the world. The benchmark specifications are intended for use by reactor designers, safety analysts and nuclear data evaluators to validate calculation techniques and data. Example calculations are presented; these do not constitute a validation or endorsement of the codes or cross-section data. The 2015 edition of the International Handbook of Evaluated Reactor Physics Benchmark Experiments contains data from 143 experimental series that were

Physics meets fine arts: a project-based learning path on infrared imaging

Infrared imaging represents a noninvasive tool for cultural heritage diagnostics, based on the capability of IR radiation to penetrate the most external layers of different objects (as for example paintings), revealing hidden features of artworks. From an educational viewpoint, this diagnostic technique offers teachers the opportunity to address manifold topics pertaining to the physics and technology of electromagnetic radiation, with particular emphasis on the nature of color and its physical correlates. Moreover, the topic provides interesting interdisciplinary bridges towards the human sciences. In this framework, we present a hands-on learning sequence, suitable for both high school students and university freshmen, inspired by the project-based learning (PBL) paradigm, designed and implemented in the context of an Italian national project aimed at offering students the opportunity to participate in educational activities within a real working context. In a preliminary test we involved a group of 23 high school students while they were working as apprentices in the Laboratory of Applied Physics for Cultural Heritage (ArcheoLab) at the University of Calabria. Consistently with the PBL paradigm, students were given well-defined practical goals to be achieved. As final goals they were asked (i) to construct and to test a low cost device (based on a disused commercial camera) appropriate for performing educational-grade IR investigations on paintings, and (ii) to prepare a device working as a simple spectrometer (recycling the optical components of a disused video projector), suitable for characterizing various light sources in order to identify the most appropriate for infrared imaging. The proposed learning path has shown (in the preliminary test) to be effective in fostering students’ interest towards physics and its technological applications, especially because pupils perceived the context (i.e. physics applied to the protection and restoration of cultural

At present, there is an urgent need to preserve integral reactor physics experimental data including separate or special effects data for nuclear energy and technology applications and the knowledge and competence contained therein. The International Reactor Physics Evaluation Project (IRPhEP) was initiated as a pilot activity in 1999 by the Organization of Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). The project was endorsed as an official activity of the NSC in June of 2003. While coordination and administration of the IRPhEP takes place at an international level, each participating country is responsible for the administration, technical direction, and priorities of the project within their respective countries. This document outlines the general presentation guidelines that evaluators should follow for the description of the experiments and all relevant experimental data in order to ensure the consistency between the evaluations published in the final Handbook. Publication templates will be used to ensure this consistency and will follow the general scheme below: 1 - Experiment identification number; 2- Date; 3 - Name of experiment (Purpose of experiment, Phenomena measured and scope); 4 - Name or designation of experimental programme; 5 - Description of facility; 6 - Description of test or experiment (Experimental configuration, Core life cycle, Experimental limitations or shortcomings); 7 - Phenomena measured (Description of results and analysis, Special features and characteristics of experiment, Measurement systems/methods and uncertainties); 8 - Duplicate or complementary experiments / other related experiments; 9 - Status of completion of the evaluation; 10 - References (pointer to evaluation, archive if available, otherwise generic bibliographic reference); 11 - Authors/ organisers 12 - Material available

MESA. An ERL project for particle physics experiments

Hug, Florian [Institut fuer Kernphysik, Universitaet Mainz (Germany)

2016-07-01

The Mainz Energy-recovering Superconducting Accelerator (MESA) will be constructed at the Institut fuer Kernphysik of the Johannes Gutenberg University of Mainz. The accelerator is a low energy continuous wave (CW) recirculating electron linac for particle physics experiments. MESA will be operated in two different modes serving mainly two experiments: the first is the external beam (EB) mode, where the beam is dumped after being used with the external fixed target experiment P2, whose goal is the measurement of the weak mixing angle with highest accuracy. The required beam current for P2 is 150 μA with polarized electrons at 155 MeV. In the second operation mode MESA will be run as an energy recovery linac (ERL). In an ERL the energy of the electrons is recovered after their experimental use by decelerating them in the superconducting acceleration cavities. The experiment served in this mode is a (pseudo) internal fixed target experiment named MAGIX. It demands an unpolarized beam of 1 mA at 105 MeV. In a later construction stage of MESA the achievable beam current in ERL-mode shall be upgraded to 10 mA. Within this talk an overview of the MESA project will be given highlighting the challenges of operation with high density internal gas targets and the (*new*) physics applications.

2001-07-01

Motivating nonscience majors in science and mathematics studies became one of the most interesting and important challenges in contemporary science and mathematics education. Therefore, designing and studying a learning environment, which enhances students' motivation, is an important task. This experimental study sought to explore the implications of student autonomy in topic choice in a project-based Physical Science Course for nonscience majors' on students' motivational orientation. It also suggested and tested a model explaining motivational outcomes of project-based learning environment through increased student ownership of science projects. A project, How Things Work, was designed and implemented in this study. The focus of the project was application of physical science concepts learned in the classroom to everyday life situations. Participants of the study (N = 59) were students enrolled in three selected sections of a Physical Science Course, designed to fulfill science requirements for nonscience majors. These sections were taught by the same instructor over a period of an entire 16-week semester at a large public research university. The study focused on four main variables: student autonomy in choosing a project topic, their motivational orientation, student ownership of the project, and the interest in the project topic. Achievement Goal Orientation theory became the theoretical framework for the study. Student motivational orientation, defined as mastery or performance goal orientation, was measured by an Achievement Goal Orientation Questionnaire. Student ownership was measured using an original instrument, Ownership Measurement Questionnaire, designed and tested by the researchers. Repeated measures yoked design, ANOVA, ANCOVA, and multivariate regression analysis were implemented in the study. Qualitative analysis was used to complement and verify quantitative results. It has been found that student autonomy in the project choice did not make a

Preliminary evaluation of the physical impacts of a nearshore sand extraction project

International Nuclear Information System (INIS)

Anctil, F.; Ouellet, Y.

1991-01-01

A review is presented of the potential physical impacts of a nearshore sand extraction project in the Gulf of St. Lawrence. In Canada, sand extraction is mainly limited to the Beaufort Sea area, where in 1982 alone 15 million tonnes of aggregate was dredged to satisfy the requirements of offshore petroleum exploration; but there is much experience in nearshore dredging in Europe. Criteria related to impacts, developed for conditions prevailing in the North Sea (England) and the Gulf of Gascogne (France) are adapted to meet the more moderate hydrodynamic impacts of an extraction project in the Gulf of St. Lawrence. Potential impacts of extraction projects include destruction of sand bars or dunes, direct erosion resulting from beach drawdown or sedimentation interference, and impacts on littoral drift due to modified wave refraction patterns. Three schemes for the sand extraction are considered, and from the results, a fourth scheme is elaborated in such a way as to limit the negative impacts to the minor category. 17 refs., 5 figs., 4 tabs

2015-01-01

AAPM projects and collaborations in Africa Adam Shulman (AA-SC Chair) The African Affairs Subcommittee (AA-SC) of the AAPM will present a multi-institutional approach to medical physics support in Africa. Current work to increase the quality of care and level of safety for the medical physics practice in Senegal, Ghana, and Zimbabwe will be presented, along with preliminary projects in Nigeria and Botswana. Because the task of addressing the needs of medical physics in countries across Africa is larger than one entity can accomplish on its own, the AA-SC has taken the approach of joining forces with multiple organizations such as Radiating Hope and TreatSafely (NGO’s), the IAEA, companies like BrainLab, Varian and Elekta, medical volunteers and academic institutions such as NYU and Washington University.

AAPM projects and collaborations in Africa Adam Shulman (AA-SC Chair) The African Affairs Subcommittee (AA-SC) of the AAPM will present a multi-institutional approach to medical physics support in Africa. Current work to increase the quality of care and level of safety for the medical physics practice in Senegal, Ghana, and Zimbabwe will be presented, along with preliminary projects in Nigeria and Botswana. Because the task of addressing the needs of medical physics in countries across Africa is larger than one entity can accomplish on its own, the AA-SC has taken the approach of joining forces with multiple organizations such as Radiating Hope and TreatSafely (NGO’s), the IAEA, companies like BrainLab, Varian and Elekta, medical volunteers and academic institutions such as NYU and Washington University. Elements of current projects include: 1) Distance training and evaluation of the quality of contouring and treatment planning, teaching treatment planning and other subjects, and troubleshooting using modern telecommunications technology in Senegal, Ghana, and Zimbabwe; 2) Assistance in the transition from 2D to 3D in Senegal and Zimbabwe; 3) Assistance in the transition from 3D to IMRT using in-house compensators in Senegal; 4) Modernizing the cancer center in Senegal and increasing safety and; 5) Training on on 3D techniques in Ghana; 6) Assisting a teaching and training radiation oncology center to be built in Zimbabwe; 7) Working with the ISEP Program in Sub-Saharan Africa; 8) Creating instructional videos on linac commissioning; 9) Working on a possible collaboration to train physicists in Nigeria.

Full Text Available Abstract: Physics learning should be able to provide opportunities for learners to be creative in understanding the things that learned. One of the efforts made to improve the quality of physics learning was to apply the model of project based learning with virtual media. This study aimed to examine the effect of virtual media-aided model toward students’ creativity. This quasi experimental study used pretest-posttest control group design. The research instrument used a verbal and figural creativity test which had been validated by experts. Hypothesis test used employed variance test. The increase in creativity was determined based on the results of the N-gain test. The results showed that there was an increase of students' creativity in both classes. The experiment class had a higher creativity increase than the control class. Verbal and figural creativity improved in both classes. Verbal creativity increased higher than figural creativity. This shows that the model of project based learning with virtual media that applied successfully improve the students’ creativity in physics learning.

Several data suggest that physical activity and cognitive stimulation have a positive effect on the quality of life (QoL) of people with Alzheimer's disease (AD), slowing the decline due to the disease. A pilot project was undertaken to assess the effect of cognitive stimulation, physical activity, and socialization on patients with AD and their informal caregiver's QoL and mood. Fourteen patients with AD were randomly divided into active treatment group and control group. At the end of treatment, a significant improvement in apathy, anxiety, depression, and QoL in the active treatment group was found. Considering caregivers, those of the active treatment group exhibited a significant improvement in their mood and in their perception of patients' QoL. This study provides evidence that a combined approach based on cognitive stimulation, physical activity, and socialization is a feasible tool to improve mood and QoL in patients with AD and their caregivers.

"Teaching Physics as one of the humanities": The history of (harvard) project Physics, 1961-1970

Science.gov (United States)

Meshoulam, David

In the United States after World War II, science had come to occupy a central place in the minds of policy makers, scientists, and the public. Negotiating different views between these groups proved a difficult task and spilled into debates over the role and scope of science education. To examine this process, this dissertation traces the history of Harvard Project Physics (HPP), a high-school physics curriculum from the 1960s that incorporated a humanistic and historical approach to teaching science. The narrative begins with the rise of General Education in the 1940s. Under the leadership of Harvard president James Conant, faculty at Harvard developed several Natural Science courses that connected science to history as a way to teach students about science and its relationship to culture. By the late 1950s this historical approach faced resistance from scientists who viewed it as misrepresenting their disciplines and called for students to learn specialized subject matter. With the support of the National Science Foundation (NSF), in the early 1960s scientists' vision of science education emerged in high-school classrooms across the country. By the mid 1960s, with the passage of the Civil Rights Act, the Elementary and Secondary Education Act, and the Daddario Amendment to the NSF, the political and education landscape began to change. These laws transformed the goals of two of the NSF and the Office of Education (USOE). These organizations faced demands to work together to develop projects that would speak to domestic concerns over equity and diversity. Their first joint educational venture was HPP. In order to succeed, HPP had to speak to the needs of disciplinary-minded scientists at the NSF, equity-minded educators at the USOE, and results-focused politicians in Congress. This work argues that HPP succeeded because it met the needs of these various stakeholders regarding the roles of science and education in American society.

Interferometric observations have demonstrated that a significant fraction of single-dish submillimetre (submm) sources are blends of multiple submm galaxies (SMGs), but the nature of this multiplicity, i.e. whether the galaxies are physically associated or chance projections, has not been determined. We performed spectroscopy of 11 SMGs in six multicomponent submm sources, obtaining spectroscopic redshifts for nine of them. For an additional two component SMGs, we detected continuum emission but no obvious features. We supplement our observed sources with four single-dish submm sources from the literature. This sample allows us to statistically constrain the physical nature of single-dish submm source multiplicity for the first time. In three (3/7, { or} 43^{+39 }_{ -33} {per cent at 95 {per cent} confidence}) of the single-dish sources for which the nature of the blending is unambiguous, the components for which spectroscopic redshifts are available are physically associated, whereas 4/7 (57^{+33 }_{ -39} per cent) have at least one unassociated component. When components whose spectra exhibit continuum but no features and for which the photometric redshift is significantly different from the spectroscopic redshift of the other component are also considered, 6/9 (67^{+26 }_{ -37} per cent) of the single-dish sources are comprised of at least one unassociated component SMG. The nature of the multiplicity of one single-dish source is ambiguous. We conclude that physically associated systems and chance projections both contribute to the multicomponent single-dish submm source population. This result contradicts the conventional wisdom that bright submm sources are solely a result of merger-induced starbursts, as blending of unassociated galaxies is also important.

The NURESIM project, the numerical simulation platform, is developed in the frame of the NURISP European Collaborative Project (FP7), which includes 22 organizations from 14 European countries. NURESIM intends to be a reference platform providing high quality software tools, physical models, generic functions and assessment results. The NURESIM platform provides an accurate representation of the physical phenomena by promoting and incorporating the latest advances in core physics, two-phase thermal-hydraulics and fuel modelling. It includes multi-scale and multi-physics features, especially for coupling core physics and thermal-hydraulics models for reactor safety. Easy coupling of the different codes and solvers is provided through the use of a common data structure and generic functions (e.g., for interpolation between non-conforming meshes). More generally, the platform includes generic pre-processing, post-processing and supervision functions through the open-source SALOME software, in order to make the codes more user-friendly. The platform also provides the informatics environment for testing and comparing different codes. The contribution summarizes the achievements and ongoing developments of the simulation platform in core physics, thermal-hydraulics, multi-physics, uncertainties and code integration

Deepening interest in didactical problems of teaching physics can be from the beginning associated with the creation of the subject of physics, especially at secondary schools. In the 20th century it was no longer possible to ignore the rapid development of physical science and application of its results in practice. The subject of physics required the definition of its content, development of textbooks and, amongst others, new ways of teaching in comparison with the past. The interest of teachers focused mainly on increasing the clarity of explanation - the creation of experiments and teaching aids. Since 1926 Association of Mathematicians and Physicists in the first Czechoslovak Republic issued a didactic-methodological annex to the Journal of Mathematics and Physics, as a discussion in order to increase the quality of teaching. However, this action was spontaneous and subjective. In the second half of the 20th century didactics of physics became a study discipline, part of the training of future secondary school teachers and the development of scientific work in the field of Theory of teaching physics started.

We describe the evaluation by students of a scheme of open-ended, research-based group project work which has become a standard component of first-year physics courses at the University of Sydney and is now in its 19th year of operation. Data were gathered from two sources: direct observations of the classes and a written survey. A summary of the classroom observations and the results from a detailed analysis of the survey responses are presented. The feedback from the cohort of approximately 800 students is largely positive but we identify a few discrepancies between stated course goals and the results from the survey. (paper)

Social Sciences, Art and Physical Activity in Leisure Environments. An Inter-Disciplinary Project for Teacher Training

Directory of Open Access Journals (Sweden)

Full Text Available Factors such as social change and increasing urbanization processes in the early years of the 21st century have caused a reduction in the amount of time that children devote to leisure activities in the open-air, resulting in more sedentary lifestyles than children in previous decades. An education in healthy habits from early ages to increase children’s physical and mental well-being together with their level of cultural knowledge contributes to the acquisition of a Leisure Culture that allows children to perceive the close environment as a scene for learning and enjoyment. It is thus be necessary for schools to foster pedagogical experiences, taking the physical and cultural environment as teaching resources. An innovation project is proposed which will be implemented with 25 university students from the School of Teacher Training and Education at the University of Oviedo (Oviedo, Spain. The project will consist of the proposal of educational itineraries through the city of Oviedo and Mount Naranco. As teachers-to-be, students must combine knowledge of the related areas and generate inter-disciplinary activities throughout the routes that will foster respect for the environment and leisure based on culture and physical activity, attitudes that they will transmit to their own students in the future.

Rehabilitation started early during an intensive care unit (ICU) stay is associated with improved outcomes and is the basis for many quality improvement (QI) projects showing important changes in practice. However, little evidence exists regarding whether such changes are sustainable in real-world practice. To evaluate the sustained effect of a quality improvement project on the timing of initiation of active physical therapy intervention in patients with acute lung injury (ALI). This was a pre-post evaluation using prospectively collected data involving consecutive patients with ALI admitted pre-quality improvement (October 2004-April 2007, n = 120) versus post-quality improvement (July 2009-July 2012, n = 123) from a single medical ICU. The primary outcome was time to first active physical therapy intervention, defined as strengthening, mobility, or cycle ergometry exercises. Among ICU survivors, more patients in the post-quality improvement versus pre-quality improvement group received physical therapy in the ICU (89% vs. 24%, P quality improvement versus pre-quality improvement group, there was a shorter median (interquartile range) time to first physical therapy (4 [2, 6] vs. 11 d [6, 29], P quality improvement period was associated with shorter time to physical therapy (adjusted hazard ratio [95% confidence interval], 8.38 [4.98, 14.11], P quality improvement period. The following variables were independently associated with a longer time to physical therapy: higher Sequential Organ Failure Assessment score (0.93 [0.89, 0.97]), higher FiO2 (0.86 [0.75, 0.99] for each 10% increase), use of an opioid infusion (0.47 [0.25, 0.89]), and deep sedation (0.24 [0.12, 0.46]). In this single-site, pre-post analysis of patients with ALI, an early rehabilitation quality improvement project was independently associated with a substantial decrease in the time to initiation of active physical therapy intervention that was sustained over 5 years.

We evaluate different ridge-enhancement and segmentation methods to automatically extract the network architecture from time-series of Physarum plasmodia withdrawing from an arena via a single exit. Whilst all methods gave reasonable results, judged by precision-recall analysis against a ground-truth skeleton, the mean phase angle (Feature Type) from intensity-independent, phase-congruency edge enhancement and watershed segmentation was the most robust to variation in threshold parameters. The resultant single pixel-wide segmented skeleton was converted to a graph representation as a set of weighted adjacency matrices containing the physical dimensions of each vein, and the inter-vein regions. We encapsulate the complete image processing and network analysis pipeline in a downloadable software package, and provide an extensive set of metrics that characterise the network structure, including hierarchical loop decomposition to analyse the nested structure of the developing network. In addition, the change in volume for each vein and intervening plasmodial sheet was used to predict the net flow across the network. The scaling relationships between predicted current, speed and shear force with vein radius were consistent with predictions from Murray’s law. This work was presented at PhysNet 2015.

The VPH/Physiome Project is developing the model encoding standards CellML (cellml.org) and FieldML (fieldml.org) as well as web-accessible model repositories based on these standards (models.physiome.org). Freely available open source computational modelling software is also being developed to solve the partial differential equations described by the models and to visualise results. The OpenCMISS code (opencmiss.org), described here, has been developed by the authors over the last six years to replace the CMISS code that has supported a number of organ system Physiome projects. OpenCMISS is designed to encompass multiple sets of physical equations and to link subcellular and tissue-level biophysical processes into organ-level processes. In the Heart Physiome project, for example, the large deformation mechanics of the myocardial wall need to be coupled to both ventricular flow and embedded coronary flow, and the reaction-diffusion equations that govern the propagation of electrical waves through myocardial tissue need to be coupled with equations that describe the ion channel currents that flow through the cardiac cell membranes. In this paper we discuss the design principles and distributed memory architecture behind the OpenCMISS code. We also discuss the design of the interfaces that link the sets of physical equations across common boundaries (such as fluid-structure coupling), or between spatial fields over the same domain (such as coupled electromechanics), and the concepts behind CellML and FieldML that are embodied in the OpenCMISS data structures. We show how all of these provide a flexible infrastructure for combining models developed across the VPH/Physiome community. Copyright © 2011 Elsevier Ltd. All rights reserved.

Axani, S. N.; Conrad, J. M.; Kirby, C.

2017-12-01

This paper describes the construction of a desktop muon detector, an undergraduate-level physics project that develops machine-shop and electronics-shop technical skills. The desktop muon detector is a self-contained apparatus that employs a plastic scintillator as the detection medium and a silicon photomultiplier for light collection. This detector can be battery powered and is used in conjunction with the provided software. The total cost per detector is approximately 100. We describe physics experiments we have performed, and then suggest several other interesting measurements that are possible, with one or more desktop muon detectors.

Practicum in adapted physical activity: a Dewey-inspired action research project.

Science.gov (United States)

Standal, Øyvind; Rugseth, Gro

2014-07-01

The purpose of this study was to investigate what adapted physical activity (APA) students learn from their practicum experiences. One cohort of APA students participated, and data were generated from an action research project that included observations, reflective journals, and a focus group interview. The theoretical framework for the study was Dewey's and Wackerhausen's theories of reflections. The findings show the objects of students' reflections, the kind of conceptual resources they draw on while reflecting, and their knowledge interests. In addition, two paradoxes are identified: the tension between reflecting from and on own values, and how practicum as a valued experience of reality can become too difficult to handle. In conclusion, we reflect on how practicum learning can be facilitated.

Elementary particle physics in early physics education

CERN Document Server

Wiener, Gerfried

2017-01-01

Current physics education research is faced with the important question of how best to introduce elementary particle physics in the classroom early on. Therefore, a learning unit on the subatomic structure of matter was developed, which aims to introduce 12-year-olds to elementary particles and fundamental interactions. This unit was iteratively evaluated and developed by means of a design-based research project with grade-6 students. In addition, dedicated professional development programmes were set up to instruct high school teachers about the learning unit and enable them to investigate its didactical feasibility. Overall, the doctoral research project led to successful results and showed the topic of elementary particle physics to be a viable candidate for introducing modern physics in the classroom. Furthermore, thanks to the design-based research methodology, the respective findings have implications for both physics education and physics education research, which will be presented during the PhD defen...

This article reviews 10 years of engineering and physics achievements by the Large Helical Device (LHD) project with emphasis on the latest results. The LHD is the largest magnetic confinement device among diversified helical systems and employs the world's largest superconducting coils. The cryogenic system has been operated for 50,000 h in total without any serious trouble and routinely provides a confining magnetic field up to 2.96 T in steady state. The heating capability to date is 23 MW of NBI, 2.9 MW of ICRF and 2.1 MW of ECH. Negative-ion-based ion sources with the accelerating voltage of 180 keV are used for a tangential NBI with the power of 16 MW. The ICRF system has full steady-state operational capability with 1.6 MW. In these 10 years, operational experience as well as a physics database have been accumulated and the advantages of stable and steady-state features have been demonstrated by the combination of advanced engineering and the intrinsic physical advantage of helical systems in LHD. Highlighted physical achievements are high beta (5% at the magnetic field of 0.425 T), high density (1.1 x 10 21 m -3 at the central temperature of 0.4 keV), high ion temperature (T i of 5.2 keV at 1.5 x 10 19 m -3 ), and steady-state operation (3200 s with 490 kW). These physical parameters have elucidated the potential of net-current free helical plasmas for an attractive fusion reactor. It also should be pointed out that a major part of these engineering and physics achievements is complementary to the tokamak approach and even contributes directly to ITER.

The A4 project: physics data processing using the Google protocol buffer library

International Nuclear Information System (INIS)

Ebke, Johannes; Waller, Peter

2012-01-01

In this paper, we present the High Energy Physics data format, processing toolset and analysis library A4, providing fast I/O of structured data using the Google protocol buffer library. The overall goal of A4 is to provide physicists with tools to work efficiently with billions of events, providing not only high speeds, but also automatic metadata handling, a set of UNIX-like tools to operate on A4 files, and powerful and fast histogramming capabilities. At present, A4 is an experimental project, but it has already been used by the authors in preparing physics publications. We give an overview of the individual modules of A4, provide examples of use, and supply a set of basic benchmarks. We compare A4 read performance with the common practice of storing unstructured data in ROOT trees. For the common case of storing a variable number of floating-point numbers per event, speedups in read speed of up to a factor of six are observed.

Despite the physical and psychological health benefits associated with physical activity (PA) for breast cancer (BC) survivors, up to 70% of female BC survivors are not meeting minimum recommended PA guidelines. The objective of this study was to evaluate acceptability and satisfaction with Project MOVE, an innovative approach to increase PA among BC survivors through the combination of microgrants and financial incentives. A mixed-methods design was used. Participants were BC survivors and support individuals with a mean age of 58.5 years. At 6-month follow-up, participants completed a program evaluation questionnaire (n = 72) and participated in focus groups (n = 52) to explore their experience with Project MOVE. Participants reported that they were satisfied with Project MOVE (86.6%) and that the program was appropriate for BC survivors (96.3%). Four main themes emerged from focus groups: (1) acceptability and satisfaction of Project MOVE, detailing the value of the model in developing tailored group-base PA programs; (2) the importance of Project MOVE leaders, highlighting the value of a leader that was organized and a good communicator; (3) breaking down barriers with Project MOVE, describing how the program helped to address common BC related barriers; and (4) motivation to MOVE, outlining how the microgrants enabled survivors to be active, while the financial incentive motivated them to increase and maintain their PA. The findings provide support for the acceptability of Project MOVE as a strategy for increasing PA among BC survivors. © 2018 The Authors. Psycho-Oncology Published by John Wiley & Sons Ltd.

This article presents a model of educational planning held on the curricular component of physical education, developed in a collective planning context, under an extension project offered by LECEF. We underline the principles and assumptions leading the planning process adopted. We emphasize that the collective work gives us dialogue, exchange of experience, inclination to listen, overcoming the difficulties of individualism and isolation presents in the organization and realization of pedagogical work routine.

1978-01-01

Details on two versions of a computerized model for the transportation system of the NRC Physical Protection Project are presented. The Version I model permits scheduling of all types of transport units associated with a truck fleet, including truck trailers, truck tractors, escort vehicles and crews. A fixed-fleet itinerary construction process is used in which iterations on fleet size are required until the service requirements are satisfied. The Version II model adds an aircraft mode capability and provides for a more efficient non-fixed-fleet itinerary generation process. Test results using both versions are included

Process of establishing JHP project

Institute for Nuclear Study, University of Tokyo was a Japanese central research institute as regards to nuclear physics, high energy physics, and cosmic ray physics. After the foundations of National Laboratory for High Energy Physics, KEK, and Institute for Cosmic Ray Research, University of Tokyo, in early 1970s, the nuclear physics community worked out so-called NUMATRON project, which involved building a large heavy-ion synchrotron. It was, however, not successful in competition with TRISTAN project which was proposed by KEK to build a 30 GeV electron-positron collider. Alternative project of the nuclear physics community was so-called JHP (Japanese Hadron Project), to build 1 GeV proton linac in KEK site in collaboration with KEK, which included that the Institute for Nuclear Study should be consolidated to KEK leaving from The University of Tokyo. The reorganized KEK proposed in collaboration with JAEA, Japan Atomic Energy Agency, to build a big proton accelerator facility in JAEA site. This plan was realized as J-PARC, Japanese Proton Accelerator Research Complex, operating 50 GeV proton synchrotron. (author)

MO-E-18C-02: Hands-On Monte Carlo Project Assignment as a Method to Teach Radiation Physics

Energy Technology Data Exchange (ETDEWEB)

Pater, P; Vallieres, M; Seuntjens, J [McGill University, Montreal, Quebec (Canada)

2014-06-15

Purpose: To present a hands-on project on Monte Carlo methods (MC) recently added to the curriculum and to discuss the students' appreciation. Methods: Since 2012, a 1.5 hour lecture dedicated to MC fundamentals follows the detailed presentation of photon and electron interactions. Students also program all sampling steps (interaction length and type, scattering angle, energy deposit) of a MC photon transport code. A handout structured in a step-by-step fashion guides student in conducting consistency checks. For extra points, students can code a fully working MC simulation, that simulates a dose distribution for 50 keV photons. A kerma approximation to dose deposition is assumed. A survey was conducted to which 10 out of the 14 attending students responded. It compared MC knowledge prior to and after the project, questioned the usefulness of radiation physics teaching through MC and surveyed possible project improvements. Results: According to the survey, 76% of students had no or a basic knowledge of MC methods before the class and 65% estimate to have a good to very good understanding of MC methods after attending the class. 80% of students feel that the MC project helped them significantly to understand simulations of dose distributions. On average, students dedicated 12.5 hours to the project and appreciated the balance between hand-holding and questions/implications. Conclusion: A lecture on MC methods with a hands-on MC programming project requiring about 14 hours was added to the graduate study curriculum since 2012. MC methods produce “gold standard” dose distributions and slowly enter routine clinical work and a fundamental understanding of MC methods should be a requirement for future students. Overall, the lecture and project helped students relate crosssections to dose depositions and presented numerical sampling methods behind the simulation of these dose distributions.

2013-01-01

Projection installations are part of Spatially Augmented Reality, where the projection medium is used to enrich a fixed, bounded physical space with digital content. Projection technology enables us to turn many kinds of physical objects into displays. In this paper we develop and present...... a conceptual framework that addresses three aspects of a projection installation: the contentassociated with the object, the digital content, and the relation between the two. We conclude the paper with a set of strategies commonly used in projection installations: Enhancing or emphasizing physical aspects......; Transforming materiality; Adding virtual objects; 3D effects; Complex content on simple objects or simple content on complex; Strong versus loose connections between the physical object and the digital content. This paper is based on four cases, two of which concern cultural heritage installations, the others...

Geraksiev, N. S.; MPD Collaboration

2018-05-01

The Nuclotron-based Ion Collider fAcility (NICA) is a new accelerator complex being constructed at the Joint Institute for Nuclear Research (JINR). The general objective of the project is to provide beams for the experimental study of hot and dense strongly interacting QCD matter. The heavy ion programme includes two planned detectors: BM@N (Baryonic Matter at Nuclotron) a fixed target experiment with extracted Nuclotron beams; and MPD (MultiPurpose Detector) a collider mode experiment at NICA. The accelerated particles can range from protons and light nuclei to gold ions. Beam energies will span\\sqrt{s}=12-27 GeV with luminosity L ≥ 1 × 1030 cm‑2s‑1 and \\sqrt{{s}NN}=4-11 GeV and average luminosity L = 1 × 1027cm‑2 s ‑1(for 197Au79+), respectively. A third experiment for spin physics is planned with the SPD (Spin Physics Detector) at the NICA collider in polarized beams mode. A brief overview of the MPD is presented along with several observables in the MPD physics programme.

ANL/Star project: a new architecture for large scale theoretical physics computations

International Nuclear Information System (INIS)

Rushton, A.M.

1985-01-01

The project reported consists of two phases, each of which has goals of substantial physics content on its own. In Phase 1, we have selected Star Technologies' ST-100 as the array processor for the prototype coupled system and have installed one on a Vax 11/750 host. Our goals with this system are to institute a substantial program in computational physics at Argonne based on the power provided by this system and thereby to gain experience with both the hardware and software architecture of the ST-100. In Phase II, we propose to build a prototype consisting of two coupled array processors with shared memory to prove that this design can achieve high speed and efficiency in a readily extensible and cost-effective manner. This will implement all of the hardware and software modifications necessary to extend this design to as many as 64 (or more) nodes. In our design, we seek to minimize the changes made in the standard system hardware and software; this drastically reduces the effort required by our group to implement such a design and enables us to more readily incorporate the companies' upgrades to the array processor. It should be emphasized that our design is intended as a special purpose system for theoretical calculations; however it can be efficiently applied to a surprisingly broad class of problems. I shall discuss first the architecture of the ST-100 and then the physics program being currently implemented on a single system. Finally the proposed design of the coupled system is presented

The aim of this paper is to identify and show examples of good practice of public health promotion. For this, uniform quality criteria were worked out under consideration of national and international scientific literature.For the identification of examples of good practice, a comparison of different quality criteria was carried out and combined with each other in a first step. In the following step, examples of good practice were identified after a comprehensive search. The choice of the "good-practice" projects is exemplary and lays no claim to completeness.6 main quality criteria (QC) of programs promoting physical activity could be identified in the national and international context. The analysis showed altogether 10 projects which can exemplarily be classified as examples of good practice of the target groups of children and teenagers, adults, older people and people with pre-existing illnesses. These projects, however, show major differences in their (methodological) quality.The analysis reports a lack of "Good-Practice" examples. Deficits lie mainly in documentation and sustainability. Because of incomplete documentation, an assessment as a "Good-Practice" example is only possible to a limited extent; a lot of information, particularly in the evaluation, is missing. © Georg Thieme Verlag KG Stuttgart · New York.

Harnessing motivational forces in the promotion of physical activity: the Community Health Advice by Telephone (CHAT) project.

Physical inactivity among middle- and older-aged adults is pervasive, and is linked with numerous chronic conditions that diminish health and functioning. Counselor-directed physical activity programs may enhance extrinsic motivation (reflected in social influence theories, such as self-presentation theory) and, in turn, physical activity adherence, while the counselor is in charge of program delivery. However, external influences can undermine intrinsic motivation, making it more difficult to maintain physical activity once counselor-initiated contact ends. In contrast, programs that diminish the socially evaluative and controlling aspects of the counseling interchange may promote intrinsic motivation (described in cognitive evaluation theory), and, thus, physical activity maintenance, even when counselor-initiated contact ceases. The objective of the Community Health Advice by Telephone (CHAT) project is to compare these two theories by conducting a randomized controlled trial evaluating the effects of a telephone-administered counseling program delivered by a person (social influence enhancement) or computer (cognitive evaluation enhancement) on physical activity adoption and maintenance over 18 months. Healthy, sedentary adults (n = 225) aged 55 years and older are randomized to one of these programs or to a control arm. This study will contribute to advancing motivational theory as well as provide information on the sustained effectiveness of interventions with substantial public health applicability.

Full text: Since the Ukraine voluntarily accepted the status of a non-nuclear-weapons state and concluded a Safeguards Agreement with the IAEA, the Kharkov Institute of Physics and Technology (KIPT) as a nuclear facility using the nuclear material of category 1, has become a Ukrainian priority object for the international community's efforts to ensure nuclear non-proliferation measures and to bring the existing protection systems to the generally accepted security standards. In March 1996, at the meeting held under the auspices of the IAEA in Kiev, the representatives from Japan, Sweden and the USA agreed to provide technical assistance concerning improvement of the nuclear material accountancy and control and physical protection system (MPC and A) available at KIPT. The Technical Secretariat of the Japan-Ukraine Committee for Co-operation on Reducing Nuclear Weapons and Swedish Nuclear Power Inspectorate undertook to solve the most expensive and labour-consuming task namely, the upgrading of the perimeter protection system at KIPT. This included that the current perimeter system, comprising several kilometers, should be completely replaced. Besides the above-mentioned problem, the upgrading should be carried out with the institute in operation. Thus, it was not allowed to replace the existing protection system by a new one unless KIPT was constantly protected. This required the creation of a new protected zone that to a large extent was occupied by the communication equipment, buildings, trees and other objects interfering with the work. All these difficulties required very comprehensive development of the project design as well as a great deal of flexibility during the implementation of the project. These problems were all successfully resolved thanks to a well working project organization, composed of experts from KIPT, JAERI and ANS, involving the highly qualified Swedish technical experts who played a leading role. In the framework of implementation of the

The geriatric population is projected to increase dramatically over the next 10 years, and the number of abused individuals is projected to increase also. It is critical that health care providers feel competent in addressing physical elder abuse. This article presents cases illustrating the variety of presenting symptoms that may be attributed to physical elder abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

Ignitor physics assessment and confinement projections

International Nuclear Information System (INIS)

Horton, W.; Porcelli, F.; Zhu, P.; Aydemir, A.; Tajima, T.; Kishimoto, Y.

2001-01-01

An independent assessment is presented of the physics of Ignitor, a physics demonstration experiment for achieving thermonuclear ignition (where fusion alpha heating compensates for all forms of energy losses). Simulations show that a pulse of particle power up to 10-20 MW is produced for a few seconds. Crucial issues are the production of peaked density profiles over several energy confinement times, the control of current penetration for the optimization of ohmic heating, and sawtooth avoidance. The presence of a 10-20 MW ion cyclotron radio frequency system and the operation of a high-speed pellet injector are considered essential to provide added flexibility in order to counter unexpected, adverse plasma behavior.

Problems of angular momentum projection in nuclear physics

Energy Technology Data Exchange (ETDEWEB)

Sorensen, R A [Carnegie-Mellon Univ., Pittsburgh, Pa. (USA)

1977-05-09

In nuclear models approximate wave functions are often used which do not have sharp angular momentum as required of the exact wave functions. It seems obvious that model wave functions of this type should be improved by projection onto states of good angular momentum. It is not the purpose of this paper to discuss the technical difficulties of projection (which can be formidable for many particle systems), but rather to present in an elementary way certain fundamental ambiguities in the use of projection. An application to high spin states near the yrast line is suggested.

Physical, biological and clinical basis of light ions using in radiotherapy: EULIMA project

International Nuclear Information System (INIS)

Chauvel, P.

1991-01-01

Improving the efficiency of radiotherapy is a constant concern in oncology: more than half of the patients who contract cancer receive radiotherapy at some stage. Use of charged particles in radiotherapy represents indisputable progress in localization of the dose delivered to tumour masses, thereby allowing reduction of dose received by adjacent healthy tissues. Protons improve the physical selectivity of the irradiation, i.e. the dose distribution. High-LET (Linear Energy Transfer) radiations produce different biological effects, decreasing the differences in radiosensitivity, and allowing radiation therapy to control radioresistant tumours. Fast neutrons represent the most known of these high-LET particles, but they suffer of a relatively poor physical selectivity. The two approaches (physical selectivity and biological advantages) are joined in by light ions (Carbon, Oxygen, Neon). Highly selective high-LET radiation therapy can be performed for radioresistant tumours without damage to healthy tissues. Preliminary results obtained in Berkeley (USA) demonstrate an improved local control of unresectable, slowly growing tumours, confirming what could be extrapolated from proton and neutrontherapy. Furthermore, radioactive light ion beams can be used to verify the accuracy of treatment planning by checking the range of the particle with a PET camera, and in the future for the treatment itself. In the framework of its programme Europe against Cancer, the Commission of the European Communities participates in the funding of the EULIMA (European Light Ion Medical Accelerator) project feasibility study, aiming to design an hospital-based light ion therapy facility in Europe [fr

What is beautiful is good because what is beautiful is desired: physical attractiveness stereotyping as projection of interpersonal goals.

Science.gov (United States)

Lemay, Edward P; Clark, Margaret S; Greenberg, Aaron

2010-03-01

The authors posit that the attribution of desirable interpersonal qualities to physically attractive targets is a projection of interpersonal goals; people desire to form and maintain close social bonds with attractive targets and then project these motivations onto those targets. Three studies support this model. Tendencies to see attractive novel targets depicted in photographs (Study 1), attractive romantic partners (Study 2), and attractive friends (Study 3) as especially interpersonally receptive and responsive were explained by perceivers' heightened desires to bond with attractive individuals. Additional findings regarding response latencies (Study 1) also supported this model. Many instances of the "beautiful is good" effect may not reflect stereotyping as it is typically construed. Rather, they may reflect projection of heightened desires to bond with beautiful people.

There is large number of ambitious accelerator projects with promising performances in the near (and short term) future which aims at exploring energy and/or luminosity frontiers and Complementary aspects of various particles species. High Energy Physics requirements are extremely demanding with challenging parameters: entering into the new territories of the tera-scale data, high Energy or/and High (Integrated) Luminosity, high performance, high availability, long lifetime, luminosity leveling etc.. New projects are more and more challenging: larger, more powerful, more expensive, technology above present standard. Innovative ideas and breakthrough on novel technologies are key for HEP adventure. Aggressive R and D is imperative on beam and Technology related, on cost and power consumption mitigation.. There is ambitious Test Facilities to address feasibility. More and more time and (M and P) resources are required from first ideas to project proposal: it is of prime importance to launch R and D early, explore all possible options of schemes and technologies (anticipating future Physics requests), make realistic status and schedule estimates (preserve credibility and make reasonable plans). Global Collaboration is mandatory from the R and D phase to the construction and operation in order to make best use of limited resources and available expertise as inspired from successful collaborations on Detectors. The global strategy of new accelerator projects in truly world-wide collaboration aims at: - defining all various Projects and Technology options worth exploring, - taking advantage of global teams made of world-wide experts, and of synergies to address common issues (generic R and D) of various projects, - preparing together plethora of project proposals to cover Physics Landscape (ready for window opportunity), - developing Collaborative/Competition (Experts in Collaboration, Technology and Projects options in Competition), - Joining resources on (few) selected

An inadequate diet and physical inactivity may compound the many deleterious effects of smoking on health. Some research indicates that smoking behavior is related to other health behaviors, but little research has examined how smoking may be related to dietary intake of key nutrients, consumption of fast food, sedentary lifestyle, or weight status. The purpose of this study was to describe smoking frequency among adolescents and its relationship to physical activity and dietary patterns. The research study employed a cross-sectional, population-based design. Adolescents self-reported cigarette smoking, physical activity, and eating behaviors on the Project EAT (Eating Among Teens) survey and reported dietary intake on a food frequency questionnaire completed in school classrooms. The sample included 4746 middle school and high school students from Minneapolis-St. Paul public schools. Mixed-model regression, which was controlled for sex, race and ethnicity, socioeconomic status, grade level (middle school or high school), and school, was used to examine the association of smoking with diet and physical activity patterns. Overall, reported smoking frequency was inversely related to participating in team sports, eating regular meals, and consuming healthful foods and nutrients. Smoking frequency was directly related to frequency of fast-food and soft drink consumption. Adolescents who smoke cigarettes may be less likely to engage in health-promoting lifestyle behaviors. Interventions are needed to prevent smoking and the unhealthy dietary practices and physical activity behaviors that may be associated with it.

Schultz, W. E.; Stephen, L. A.; Usher, L. H.

1976-01-01

Engineering studies were performed for the Zero-G Cloud Physics Experiment liquid cooling and air pressure control systems. A total of four concepts for the liquid cooling system was evaluated, two of which were found to closely approach the systems requirements. Thermal insulation requirements, system hardware, and control sensor locations were established. The reservoir sizes and initial temperatures were defined as well as system power requirements. In the study of the pressure control system, fluid analyses by the Atmospheric Cloud Physics Laboratory were performed to determine flow characteristics of various orifice sizes, vacuum pump adequacy, and control systems performance. System parameters predicted in these analyses as a function of time include the following for various orifice sizes: (1) chamber and vacuum pump mass flow rates, (2) the number of valve openings or closures, (3) the maximum cloud chamber pressure deviation from the allowable, and (4) cloud chamber and accumulator pressure.

This report is a needs assessment and project schedule for the Health Physics Analysis Laboratory (HPAL) upgrade project at Los Alamos National Laboratory (LANL). After reviewing current and projected HPAL operations, two custom-developed laboratory information management systems (LIMS) for similar facilities were reviewed; four commercially available LIMS products were also evaluated. This project is motivated by new regulations for radiation protection and training and by increased emphasis on quality assurance (QA). HPAL data are used to: protect the health of radiation workers; document contamination levels for transportation of radioactive materials and for release of materials to the public for uncontrolled use; and verify compliance with environmental emission regulations. Phase 1 of the HPAL upgrade project concentrates on four types of counting instruments which support in excess of 90% of the sample workload at the existing central laboratories. Phase 2 is a refinement phase and also integrates summary-level databases on the central Health, Safety, and Environment (HSE) VAX. Phase 3 incorporates additional instrument types and integrates satellite laboratories into the HPAL LIMS. Phase 1 will be a multi-year, multimillion dollar project. The temptation to approach the upgrade of the HPAL program in a piece meal fashion should be avoided. This is a major project, with clearly-defined goals and priorities, and should be approached as such. Major programmatic and operational impacts will be felt throughout HSE as a result of this upgrade, so effective coordination with key customer contacts will be critical

Aravind, Vasudeva

Clarion University is located in the rolling hills of western Pennsylvania. We are a primarily undergraduate public institution serving about 6000 students. We graduate students who take different career paths, one of them being teaching physics at high schools. Since educating teachers of tomorrow requires us to introduce currently trending, research proven pedagogical methods, we incorporate several aspects of physics pedagogies such as peer instruction, flipped classroom and hands on experimentation in a studio physics lab format. In this talk, I discuss some of our projects on physics education, and seek to find potential collaborators interested in working along similar lines.

The present project is a case study founded on the decreasing motivation and engagement in physical education. The project suggests inquiry based learning (IBL) as an educational methodology. This may help to turn the trend as IBL has shown to engage and motivate students at different educational...... levels and within different subjects. In this pilot research project performed at a physical education teacher education program, qualitative methods were chosen to investigate students’ motivation and engagement within an IBL-unit in physical education and to accentuate challenges, advantages...... and disadvantages within the IBL-methodology in relation to students’ motivation. Instructed in guided inquiry, 32 students of physical education in a teacher training college worked with inquiry based learning in physical education over a four week period. During the IBL-unit, qualitative data such as the students...

1992-01-01

The basic idea of the 'AUSTRON' Project is to create an international and interdisciplinary centre of excellence, devoted to fundamental and applied research in the field of experimental physics and related topics of high technology RandD. Three alternatives have been proposed as the basic facility of this centre: either an electron-positron ring collider for a tau-charm factory, or a smaller ring for a phi factory, or a proton accelerator for a spallation source. That should be complemented by a synchrotron radiation facility, constituting an important link between physics, biology, medicine and the industry. 'AUSTRON' should also include a test beam facility for radiation detector development, a RandD laboratory for micro-electronics, a scientific computing centre linked to international networks, and a centre of education.

The prevalence of non-communicable diseases (NCDs) is increasing worldwide, also among children. Information about primary prevention of NCD's is increasing; however, convincing strategies among children is needed. The present paper describes the design and methods in the Health Oriented Pedagogical Project (HOPP) study. The main objective is to evaluate the effects of a school-based physical activity intervention program on cardio-metabolic risk factors. Secondary objectives include assessment of physical, psychological and academic performance variables. The HOPP study is a 7 years longitudinal large-scale controlled intervention in seven elementary schools (n = 1545) with two control schools (n = 752); all aged 6-11 years at baseline. The school-based physical activity intervention program includes an increase in physical activity (PA) of 225 min/week as an integrated part of theoretical learning, in addition to the curriculum based 90 min/week of ordinary PA. Primary outcomes include cardio-metabolic risk factors measured as PA level, BMI status, waist circumference, muscle mass, percent fat, endurance test performance, total serum cholesterol, high-density lipoprotein (HDL), non-HDL, micro C-reactive protein (mCRP) and long-term blood sugar (HbA1c). In addition, secondary outcomes include anthropometric growth measures, physical fitness, quality of life (QoL), mental health, executive functions, diet and academic performance. HOPP will provide evidence of effects on cardio-metabolic risk factors after a long-term PA intervention program in elementary schoolchildren. School-based PA intervention programs may be an effective arena for health promotion and disease prevention. The study is registered in Clinical trials (ClinicalTrials.gov Identifier: NCT02495714 ) as of June 20 th - 2015, retrospectively registered. The collection of baseline values was initiated in mid-January 2015.

Sexuality and physical contact in National Social Life, Health, and Aging Project Wave 2.

Galinsky, Adena M; McClintock, Martha K; Waite, Linda J

2014-11-01

Wave 2 of the National Social Life, Health, and Aging Project (NSHAP) includes new measures of sexual interest and behavior, as well as new measures of the context of sexual experience and the frequency and appeal of physical contact. This is the first time many of these constructs have been measured in a nationally representative sample. We describe the new measures and compare the distributions of each across gender and age groups, in some cases by partnership status. Two components of sexuality decrease with age among both men and women: frequency of finding an unknown person sexually attractive and receptivity to a partner's sexual overtures. In contrast, the inclination to make one's self sexually attractive to others was a more complicated function of partner status, gender, and age: partnered women and unpartnered men made the most effort, with the more effortful gender's effort decreasing with age. Both men and women find nonsexual physical contact appealing but sexual physical contact is more appealing to men than women. Finally, two fifths of men and women report dissatisfaction with their partner's frequency of caring behaviors that make later sexual interactions pleasurable, and a fifth of women and a quarter of men who had vaginal sex in the past year report dissatisfaction with amount of foreplay. These data offer the opportunity to characterize sexual motivation in older adulthood more precisely and richly and to examine how the context of sexual experience and the nonsexual aspects of physical intimacy correlate with sexual behavior, enjoyment, and problems. © The Author 2014.

The laboratory 'Physics of ionic and molecular interactions' (PIIM) is a mixed research unit (UMR6633) between the CNRS and the Provence University in Marseille. PIIM is in the Provence region the leading laboratory for the study of dilute matter, and brings together physicists and physico-chemists for studying gases and plasmas, and their interactions with matter and radiation. Our research activities are principally fundamental, and most often mobilize our interdisciplinary talent. They mainly belong to three research axis: atomic physics and radiation, plasma physics, and surface reactivity. The first axis corresponds to fundamental atomic physics experiments performed in ion traps, and to many studies using the atom and ion radiation for diagnosing the gases and plasmas. Experimental and theoretical researches of the dynamic and radiative properties of plasmas constitute the second research axis. The third axis concerns the analysis of reactivity on surfaces in a neutral or ionized environment. PIIM has a permanent staff of 14 CNRS researcher, 36 professors, and 19 engineers or technicians. Our flux of graduate students, postdoctoral fellows is of about twenty. The laboratory provides a management staff, and workshops for mechanics, electronics, instrumentation and computers. We are structured in six research teams developing 12 experiments. Ion confinement and laser manipulations (CIML): The research developed by this team consists in the confinement of ions in an electromagnetic trap. Experiments at the forefront of atomic physics master the confinement of a single ion. A metrology project aims to the achievement of a frequency standard in the optical range. Gas and plasma diagnosis (DGP): The modeling of radiative properties of different types of plasma is the main activity for this team. Numerous national and international collaborations result in the diagnostic of laboratory, astrophysical and thermonuclear fusion plasmas, and in the development of

A physical activity and nutrition community intervention called the Oxford Hills Healthy Moms (OHHM) Project was developed using a multifaceted social marketing process, including review of state surveillance results, key informant interviews, and a survey and focus group discussions with low-socioeconomic-status (low-SES) mothers. This formative work was used to make key decisions on the selection of the intervention region, segmentation of the audience, and design of intervention strategies addressing multiple levels of the socioecological model. The OHHM Project aims to increase fruit and vegetable consumption and physical activity levels among low-SES mothers in the Oxford Hills region of Maine. The OHHM Project includes five components: (a) physical activity buddy program, (b) cooking club with education, (c) fruit and vegetable discount buying club with education, (d) increased access to produce vendors, and (e) increased access to places for physical activity.

Accelerators are the largest and most costly scientific instruments of the Department of Energy, with uses across a broad range of science, including colliders for particle physics and nuclear science and light sources and neutron sources for materials studies. COMPASS, the Community Petascale Project for Accelerator Science and Simulation, is a broad, four-office (HEP, NP, BES, ASCR) effort to develop computational tools for the prediction and performance enhancement of accelerators. The tools being developed can be used to predict the dynamics of beams in the presence of optical elements and space charge forces, the calculation of electromagnetic modes and wake fields of cavities, the cooling induced by comoving beams, and the acceleration of beams by intense fields in plasmas generated by beams or lasers. In SciDAC-1, the computational tools had multiple successes in predicting the dynamics of beams and beam generation. In SciDAC-2 these tools will be petascale enabled to allow the inclusion of an unprecedented level of physics for detailed prediction

The Office of Material Management and Minimization (M3) Reactor Conversion Fuel Thermo-Physical Characterization Project at Pacific Northwest National Laboratory (PNNL) was tasked with using PNNL facilities and processes to receive irradiated low enriched uranium–molybdenum (LEU-Mo) fuel plate samples and perform analysis in support of the M3 Reactor Conversion Program. This work is in support of the M3 Reactor Conversion Fuel Development Pillar that is managed by Idaho National Laboratory. The primary research scope was to determine the thermo-physical properties as a function of temperature and burnup. Work conducted in Fiscal Year (FY) 2014 complemented measurements performed in FY 2013 on four additional irradiated LEU-Mo fuel plate samples. Specifically, the work in FY 2014 investigated the influence of different processing methods on thermal property behavior, the absence of aluminum alloy cladding on thermal property behavior for additional model validation, and the influence of higher operating surface heat flux / more aggressive irradiation conditions on thermal property behavior. The model developed in FY 2013 and refined in FY 2014 to extract thermal properties of the U-Mo alloy from the measurements conducted on an integral fuel plate sample (i.e., U-Mo alloy with a thin Zr coating and clad in AA6061) continues to perform very well. Measurements conducted in FY 2014 on samples irradiated under similar conditions compare well to measurements performed in FY 2013. In general, there is no gross influence of fabrication method on thermal property behavior, although the difference in LEU-Mo foil microstructure does have a noticeable influence on recrystallization of grains during irradiation. Samples irradiated under more aggressive irradiation conditions, e.g., higher surface heat flux, revealed lower thermal conductivity when compared to samples irradiated at moderate surface heat fluxes, with the exception of one sample.

Physical activity, social network type, and depressive symptoms in late life: an analysis of data from the National Social Life, Health and Aging Project.

Science.gov (United States)

Litwin, Howard

2012-01-01

To clarify whether physical activity among older Americans is associated with depressive symptoms, beyond the effects of social network type, physical health, and sociodemographic characteristics. The analysis used data from a sub-sample, aged 65–85, from the National Social Life, Health and Aging Project (N=1349). Hierarchical regressions examined the respective effects of selected network types and extent of engagement in physical activity on depressive symptoms, controlling for physical health and sociodemographic background. The findings showed that physical activity was correlated inversely with late life depressive symptoms. However, when interaction terms for the selected social network types and the extent of physical activity were also considered, the main effect of social network on depressive symptoms increased, while that of physical activity was eliminated. The results show that older American adults embedded in family network types are at risk of limited physical activity. However, interventions aimed to increase their engagement in physical activity might help to reduce depressive symptoms within this group.

The Reactor Physics and Department of SCK-CEN offers expertise in various areas of reactor physics, in particular in neutronics calculations, reactor dosimetry, reactor operation, reactor safety and control and non-destructive analysis on reactor fuel. This expertise is applied within the Reactor Physics and MYRRHA Research Department's own research projects in the VENUS critical facility, in the BR1 reactor and in the MYRRHA project (this project aims at designing a prototype Accelerator Driven System). Available expertise is also used in programmes external to the Department such as the reactor pressure steel vessel programme, the BR2 reactor dosimetry, and the preparation and interpretation of irradiation experiments. Progress and achievements in 1999 in the following areas are reported on: (1) investigations on the use of military plutonium in commercial power reactors; (2) neutron and gamma calculations performed for BR-2 and for other reactors; (3) the updating of neutron and gamma cross-section libraries; (4) the implementation of reactor codes; (6) the management of the UNIX workstations; and (6) fuel cycle studies

The Cea multi-scale and multi-physics simulation project for nuclear applications

Full text of publication follows. Today numerical modelling is everywhere recognized as an essential tool of capitalization, integration and share of knowledge. For this reason, it becomes the central tool of research. Until now, the Cea developed a set of scientific software allowing to model, in each situation, the operation of whole or part of a nuclear installation and these codes are largely used in nuclear industry. However, for the future, it is essential to aim for a better accuracy, a better control of uncertainties and better performance in computing times. The objective is to obtain validated models allowing accurate predictive calculations for actual complex nuclear problems such as fuel behaviour in accidental situation. This demands to master a large and interactive set of phenomena ranging from nuclear reaction to heat transfer. To this end, Cea, with industrial partners (EDF, Framatome-ANP, ANDRA) has designed an integrated platform of calculation, devoted to the study of nuclear systems, and intended at the same time for industries and scientists. The development of this platform is under way with the start in 2005 of the integrated project NURESIM, with 18 European partners. Improvement is coming not only through a multi-scale description of all phenomena but also through an innovative design approach requiring deep functional analysis which is upstream from the development of the simulation platform itself. In addition, the studies of future nuclear systems are increasingly multidisciplinary (simultaneous modelling of core physics, thermal-hydraulics and fuel behaviour). These multi-physics and multi-scale aspects make mandatory to pay very careful attention to software architecture issues. A global platform is thus developed integrating dedicated specialized platforms: DESCARTES for core physics, NEPTUNE for thermal-hydraulics, PLEIADES for fuel behaviour, SINERGY for materials behaviour under irradiation, ALLIANCES for the performance

The CPT project came to an end in December 2006 and its original scope is now shared among three new areas, namely Computing, Offline and Physics. In the physics area the basic change with respect to the previous system (where the PRS groups were charged with detector and physics object reconstruction and physics analysis) was the split of the detector PRS groups (the old ECAL-egamma, HCAL-jetMET, Tracker-btau and Muons) into two groups each: a Detector Performance Group (DPG) and a Physics Object Group. The DPGs are now led by the Commissioning and Run Coordinator deputy (Darin Acosta) and will appear in the correspond¬ing column in CMS bulletins. On the physics side, the physics object groups are charged with the reconstruction of physics objects, the tuning of the simulation (in collaboration with the DPGs) to reproduce the data, the provision of code for the High-Level Trigger, the optimization of the algorithms involved for the different physics analyses (in collaboration with the analysis gr...

The role of physics departments in the recruitment, preparation and support of pre-college teachers of physics

2008-05-01

The United States faces a critical shortage of qualified physics and physical science teachers. The number of high school students taking physics is increasing but the number of physics majors pursuing careers in pre-college teaching is not nearly sufficient to meet the demand. College and university physics departments have content expertise and ready access to potential future teachers of physics. In order to address the crisis in physics and physical science education, APS, AAPT, and AIP have developed the PhysTEC project. Seattle Pacific University is one of six fully funded PhysTEC sites. The PhysTEC project also supports a coalition of more than one hundred institutions that are committed to improving K-12 physics and physical science education. This talk will describe the national PhysTEC project along with our local PhysTEC program. We will explore ways in which physics departments can more fully integrate the preparation of pre-college physics teachers within existing departmental priorities. We will discuss opportunities for regional partnerships between 2-year and 4-year colleges, school districts, and teacher preparation programs. We will also highlight ways in which our research on the learning and teaching of physics informs the development of tools that teachers and teacher educators can use to diagnose student ideas and to design subsequent instruction that capitalizes on these ideas.

Nelson, D.O.

1995-05-01

One of the great success stories of modern molecular genetics has been the ability of biologists to isolate and characterize the genes responsible for serious inherited diseases like fragile X syndrome, cystic fibrosis and myotonic muscular dystrophy. This dissertation concentrates on constructing high-resolution physical maps. It demonstrates how probabilistic modeling and statistical analysis can aid molecular geneticists in the tasks of planning, execution, and evaluation of physical maps of chromosomes and large chromosomal regions. The dissertation is divided into six chapters. Chapter 1 provides an introduction to the field of physical mapping, describing the role of physical mapping in gene isolation and ill past efforts at mapping chromosomal regions. The next two chapters review and extend known results on predicting progress in large mapping projects. Such predictions help project planners decide between various approaches and tactics for mapping large regions of the human genome. Chapter 2 shows how probability models have been used in the past to predict progress in mapping projects. Chapter 3 presents new results, based on stationary point process theory, for progress measures for mapping projects based on directed mapping strategies. Chapter 4 describes in detail the construction of all initial high-resolution physical map for human chromosome 19. This chapter introduces the probability and statistical models involved in map construction in the context of a large, ongoing physical mapping project. Chapter 5 concentrates on one such model, the trinomial model. This chapter contains new results on the large-sample behavior of this model, including distributional results, asymptotic moments, and detection error rates. In addition, it contains an optimality result concerning experimental procedures based on the trinomial model. The last chapter explores unsolved problems and describes future work

Active target detection systems, where the gas used as the detection medium is also a target for nuclear reactions, have been used for a wide variety of nuclear physics applications since the eighties. Improvements in Micro-Pattern Gaseous Detectors (MPGDs) and in micro-electronics achieved in the last decade permit the development of a new generation of active targets with higher granularity pad planes that allow spatial and time information to be determined with unprecedented accuracy. A novel active target and time projection chamber (ACTAR TPC), that will be used to study reactions and decays of exotic nuclei at facilities such as SPIRAL2, is presently under development and will be based on MPGD technology. Several MPGDs (Micromegas and Thick GEM) coupled to a 2×2 mm{sup 2} pixelated pad plane have been tested and their performances have been determined with different gases over a wide range of pressures. Of particular interest for nuclear physics experiments are the angular and energy resolutions. The angular resolution has been determined to be better than 1° FWHM for short traces of about 4 cm in length and the energy resolution deduced from the particle range was found to be better than 5% for 5.5 MeV α particles. These performances have been compared to Geant4 simulations. These experimental results validate the use of these detectors for several applications in nuclear physics.

To explore cross-sectional adherence to cancer prevention recommendations by adults enrolled in a prospective cohort in Alberta, Canada. Questionnaire data were used to construct a composite cancer prevention adherence score for each participant, based on selected personal recommendations published by the World Cancer Research Fund/American Institute for Cancer Research (2007). Data were self-reported on health and lifestyle, past-year physical activity and past-year FFQ. The scores accounted for physical activity, dietary supplement use, body size, and intakes of alcohol, fruit, vegetables and red meat. Tobacco exposure was also included. Scores ranged from 0 (least adherent) to 7 (most adherent). Alberta's Tomorrow Project; a research platform based on a prospective cohort. Adult men and women (n 24 988) aged 35-69 years recruited by random digit dialling and enrolled in Alberta's Tomorrow Project between 2001 and 2009. Of the cohort, 14 % achieved adherence scores ≥5 and 60 % had scores ≤3. Overall adherence scores were higher in women (mean (sd): 3·4 (1·1)) than in men (3·0 (1·2)). The extent of overall adherence was also associated with level of education, employment status, annual household income, personal history of chronic disease, family history of chronic disease and age. Reported adherence to selected personal recommendations for cancer prevention was low in this cohort of adults. In the short to medium term, these results suggest that more work is required to identify behaviours to target with cancer prevention strategies at a population level. Future work will explore the associations between adherence scores and cancer risk in this cohort.

Projection-based curve clustering

International Nuclear Information System (INIS)

Auder, Benjamin; Fischer, Aurelie

2012-01-01

This paper focuses on unsupervised curve classification in the context of nuclear industry. At the Commissariat a l'Energie Atomique (CEA), Cadarache (France), the thermal-hydraulic computer code CATHARE is used to study the reliability of reactor vessels. The code inputs are physical parameters and the outputs are time evolution curves of a few other physical quantities. As the CATHARE code is quite complex and CPU time-consuming, it has to be approximated by a regression model. This regression process involves a clustering step. In the present paper, the CATHARE output curves are clustered using a k-means scheme, with a projection onto a lower dimensional space. We study the properties of the empirically optimal cluster centres found by the clustering method based on projections, compared with the 'true' ones. The choice of the projection basis is discussed, and an algorithm is implemented to select the best projection basis among a library of orthonormal bases. The approach is illustrated on a simulated example and then applied to the industrial problem. (authors)

The Office of Material Management and Minimization Fuel Thermo-physical Characterization Project at Pacific Northwest National Laboratory (PNNL) is tasked with using PNNL facilities and processes to receive irradiated low enriched uranium-molybdenum fuel plate samples and perform analyses in support of the Office of Material Management and Minimization Reactor Conversion Program. This work is in support of the Fuel Development Pillar that is managed by Idaho National Laboratory. A key portion of the scope associated with this project was to measure the thermal properties of fuel segments harvested from plates that were irradiated in the Advanced Test Reactor. Thermal diffusivity of samples prepared from the fuel segments was measured using laser flash analysis. Two models, one developed by PNNL and the other developed by the Technische Universität München (TUM), were evaluated to extract the thermal diffusivity of the uranium-molybdenum alloy from measurements made on the irradiated, layered composites. The experimental data of the “TC” irradiated fuel segment was evaluated using both models considering a three-layer and five-layer system. Both models are in acceptable agreement with one another and indicate that the zirconium diffusion barrier has a minimal impact on the overall thermal diffusivity of the monolithic U-Mo fuel.

Project U-Turn: increasing active transportation in Jackson, Michigan.

Science.gov (United States)

TenBrink, David S; McMunn, Randall; Panken, Sarah

2009-12-01

Jackson, Michigan, is a medium-sized city suffering from a bad economy and obesity-related health issues. Nearly 20% of the 36,000 residents live below the poverty line. It is a relatively young city (median age of 30 years) with a mixed ethnicity (20% black, 73% white, 4% Hispanic). The city offers many structured, active recreational opportunities, but has not integrated physical activity into daily life. Project U-Turn aimed to increase active transportation (e.g., biking, walking, and transit use) through an integrated approach to Active Living by Design's community action model and the Michigan Safe Routes to School model. Resources were focused on active living promotions and programs; partnership meetings were the source of changes in policy and physical projects. Each initiative was designed to introduce each of the 5Ps (preparation, promotion, programs, policy, and physical projects) to build support for the partnership's overall work. The partnership collected snapshot data of community walking and biking behavior, percentage of students walking to school, participation in events and programs, and new physical projects. Jackson saw a vast improvement in physical infrastructure and policy and a related increase in walking and biking in the community. The project engaged in purposeful partnership building to implement effective programs and promotions that built support for policy and physical projects.

Mais especificamente, o objeto de discussão deste texto são os projetos de ensino. Atualmente,no âmbito dos debates sobre organização curricular, a Pedagogia de Projetos tem se mostrado como uma alternativa de trabalho que permite a construção do conhecimento em sua totalidade. Mas como isso acontece? Ainda se faz necessária a discussão sobre o que é Pedagogia de Projetos, como esta vem sendo trabalhada na educação infantil e também como a Educação Física pode ser construída dentro dessa proposta. Este texto se compromete a realizar algumas indicações, possíveis caminhos em busca de uma legítima presença da Educação Física na educação infantil. PALAVRAS-CHAVE: Pedagogia de Projetos - Educação Física - Educação infantil. This article discusses the presence of Physical Education in the education of children, analysing the conceptions about Infancy, Infant Education and Physical Education and how these concepts influence the construction of pedagogical propositions and educational interventions at school. More specifically, the object of discussion of this text are the teaching projects. Currently, in the sphere of the debates over syllabus organization, Project Pedagogy has presented itself as an alternative that allows knowledge building in its totality. But how does it happen? There still needs to be more debate over what Project Pedagogy really is, how it has been used in Infant Education and also how Physical Education can be built within this proposal. This text aims at indicating possible paths in search of a legitimate presence of Physical Education in Infant Education. KEY WORDS: Project Pedagogy - Physical Education - Infant education.

International Atomic Energy Agency(IAEA) had established security-related department and has been strengthening security measures against possible sabotage. IAEA enforces the recommendations for the physical protection of NPPs in the INFCIRC/ 225/Rev.5 to the member states and U.S. NRC also enforces the similar requirements in 10 CFR 73.55. Thus, in order to let Korean NPPs meet the new requirements in INFCIRC/225/Rev.5 or U.S. NRC requirements, Korea nuclear licensee should develop or establish appropriate physical protection system (PPS) design methods for the physical protection of the operating NPPs and new NPPs. KHNP is doing the project of 'Development of APR1400 Physical Protection System Design (2012- 2015, KHNP/KAERI /KEPCO E-C)'. This paper describes overview of a physical protection system (PPS) design and evaluation for an advanced nuclear power plant. It found that a new physical protection system (PPS)design and evaluation. KHNP is doing the project of Physical Protection System design according to U.S. NRC requirements and IAEA requirements in INFCIRC /225 /Rev.5 and will complete by 7.31, 2015 for development of APR1400 Physical Protection System. After completing this project, the results of project are expected to apply new NPPs.

The Tokamak Fusion Test Reactor decontamination and decommissioning project and the Tokamak Physics Experiment at the Princeton Plasma Physics Laboratory. Environmental Assessment

Energy Technology Data Exchange (ETDEWEB)

1994-05-27

If the US is to meet the energy needs of the future, it is essential that new technologies emerge to compensate for dwindling supplies of fossil fuels and the eventual depletion of fissionable uranium used in present-day nuclear reactors. Fusion energy has the potential to become a major source of energy for the future. Power from fusion energy would provide a substantially reduced environmental impact as compared with other forms of energy generation. Since fusion utilizes no fossil fuels, there would be no release of chemical combustion products to the atmosphere. Additionally, there are no fission products formed to present handling and disposal problems, and runaway fuel reactions are impossible due to the small amounts of deuterium and tritium present. The purpose of the TPX Project is to support the development of the physics and technology to extend tokamak operation into the continuously operating (steady-state) regime, and to demonstrate advances in fundamental tokamak performance. The purpose of TFTR D&D is to ensure compliance with DOE Order 5820.2A ``Radioactive Waste Management`` and to remove environmental and health hazards posed by the TFTR in a non-operational mode. There are two proposed actions evaluated in this environmental assessment (EA). The actions are related because one must take place before the other can proceed. The proposed actions assessed in this EA are: the decontamination and decommissioning (D&D) of the Tokamak Fusion Test Reactor (TFTR); to be followed by the construction and operation of the Tokamak Physics Experiment (TPX). Both of these proposed actions would take place primarily within the TFTR Test Cell Complex at the Princeton Plasma Physics Laboratory (PPPL). The TFTR is located on ``D-site`` at the James Forrestal Campus of Princeton University in Plainsboro Township, Middlesex County, New Jersey, and is operated by PPPL under contract with the United States Department of Energy (DOE).

The DataGrid Project

Ruggieri, F

2001-01-01

An overview of the objectives and status of the DataGrid Project is presented, together with a brief introduction to the Grid metaphor and some references to the Grid activities and initiatives related to DataGrid. High energy physics experiments have always requested state of the art computing facilities to efficiently perform several computing activities related with the handling of large amounts of data and fairly large computing resources. Some of the ideas born inside the community to enhance the user friendliness of all the steps in the computing chain have been, sometimes, successfully applied also in other contexts: one bright example is the World Wide Web. The LHC computing challenge has triggered inside the high energy physics community, the start of the DataGrid Project. The objective of the project is to enable next generation scientific exploration requiring intensive computation and analysis of shared large-scale databases. (12 refs).

Health Physics Laboratory - Overview

Olko, P.

2000-01-01

Full text: The activities of the Health Physics Laboratory at the Institute of Nuclear Physics in Cracow are principally research in the general area of radiation physics, and radiation protection of the employees of the Institute of Nuclear Physics. Theoretical research concerns modelling of radiation effects in radiation detectors and studies of concepts in radiation protection. Experimental research, in the general area of solid state dosimetry, is primarily concerned with thermoluminescence (TL) dosimetry, and more specifically: development of LiF:Mg, Ti and CVD diamond detectors for medical applications in conventional and hadron radiotherapy and of LiF:Mg, Cu, P for low-level natural external ionising radiation. Environmental radiation measurements (cosmic-rays on aircraft and radon in dwellings and soil) are also performed using track CR-39 and TLD detectors. The Laboratory provides expert advice on radiation protection regulations at national and international levels. Routine work of the Health Physics Laboratory involves design and maintenance of an in-house developed TL-based personnel dosimetry system for over 200 radiation workers at the INP, supervision of radiation safety on INP premises, and advising other INP laboratories on all matters pertaining to radiation safety. We provide personal and environmental TLD dosimetry service for several customers outside the INP, mainly in hospitals and nuclear research institutes in Poland. We also calibrate radiation protection instruments for customers in southern Poland. The year 2000 was another eventful year for the Health Physics Laboratory. We started three new research projects granted by the Polish State Committee of Scientific Research. Mr P. Bilski co-ordinates the project on the measurements of radiation doses on board of commercial aircraft of Polish LOT Airlines. Dr B. Marczewska and I worked on the application of artificial diamonds for dosimetry of ionising radiation. We also participate in a

We report on the work done in massively parallel processing with a view to studying possible solutions for extracting interesting high-energy physics particle events at future high-luminosity hadronic colliders operating in the TeV energy domain. We concentrate on a special Single Instruction Multiple Data (SIMD) architecture: the Associative String Processor (ASP). The Massively Parallel Processing Collaboration (MPPC) Project, grouping nine European institutes, was launched by CERN to carry out this RandD programme. This report, written by partners of the MPPC collaboration, describes the main results achieved at the end of the project: construction of ASP machines, parallel software development and application studies in high-energy physics and in other fields of science. A final, positive assessment of the ASP concept has been made by the Collaboration. (orig.)

Navigating Earthquake Physics with High-Resolution Array Back-Projection

Science.gov (United States)

Meng, Lingsen

Understanding earthquake source dynamics is a fundamental goal of geophysics. Progress toward this goal has been slow due to the gap between state-of-art earthquake simulations and the limited source imaging techniques based on conventional low-frequency finite fault inversions. Seismic array processing is an alternative source imaging technique that employs the higher frequency content of the earthquakes and provides finer detail of the source process with few prior assumptions. While the back-projection provides key observations of previous large earthquakes, the standard beamforming back-projection suffers from low resolution and severe artifacts. This thesis introduces the MUSIC technique, a high-resolution array processing method that aims to narrow the gap between the seismic observations and earthquake simulations. The MUSIC is a high-resolution method taking advantage of the higher order signal statistics. The method has not been widely used in seismology yet because of the nonstationary and incoherent nature of the seismic signal. We adapt MUSIC to transient seismic signal by incorporating the Multitaper cross-spectrum estimates. We also adopt a "reference window" strategy that mitigates the "swimming artifact," a systematic drift effect in back projection. The improved MUSIC back projections allow the imaging of recent large earthquakes in finer details which give rise to new perspectives on dynamic simulations. In the 2011 Tohoku-Oki earthquake, we observe frequency-dependent rupture behaviors which relate to the material variation along the dip of the subduction interface. In the 2012 off-Sumatra earthquake, we image the complicated ruptures involving orthogonal fault system and an usual branching direction. This result along with our complementary dynamic simulations probes the pressure-insensitive strength of the deep oceanic lithosphere. In another example, back projection is applied to the 2010 M7 Haiti earthquake recorded at regional distance. The

Haugen, Tommy; Ommundsen, Yngvar; Seiler, Stephen

2013-02-01

The aim of this study was to investigate if physical fitness (strength/power, endurance, flexibility and coordination) mediates the cross-sectional relationship between physical activity and physical self-perception (athletic competence and physical appearance) in a sample of 15-year old adolescents. We wanted to investigate the relative strength of each indirect effect. The present data are taken from two waves of a larger data collection for the project "Youth in Balance", and was collected in the autumn of 2005 (N = 1207) and 2008 (N = 632). A total of 1839 students (889 girls and 950 boys) from 12 schools in Kristiansand took part. A bias-corrected bootstrapping technique was used to examine indirect effects. Results revealed that cardiovascular endurance, lower-body strength/power, and upper-body strength stood out as unique mediators in the relationship between physical activity and athletic competence in both genders. Furthermore, there was an indirect effect of physical activity on physical appearance through physical strength/power and flexibility in males. No indirect effects of physical activity on physical appearance through actual physical fitness indices were detected in females.

This report summarizes the accomplishments of the project ''Studies of nuclear reactions at very low energies''. This project was undertaken in 1987 and completed in 1993. All but one of the major objectives of this study have been accomplished. Specifically the authors have completed their investigation of the (p,γ) on light nuclei, a study of the Oppenheimer-Phillips effect, a measurements of the astrophysically interesting reaction D(α,γ) 6 Li at low energies and an extension of the reaction D(d,γ) 4 He to lower energies than previously observed. Preliminary investigation of te reaction 7 Li( 3 He,p) 9 Be was begun and is continuing under a separate DOE grant. In addition to these tasks, they have completed some very interesting projects which were not included in the original proposal. These include a study of the (d,γ) reactions on 6 Li, 7 Li and 10 B and an investigation of the possibility of observing terrestrial antineutrinos from the beta decay chains of U and Th as a diagnostic of terrestrial heat flow

Projected regression method for solving Fredholm integral equations arising in the analytic continuation problem of quantum physics

International Nuclear Information System (INIS)

Arsenault, Louis-François; Millis, Andrew J; Neuberg, Richard; Hannah, Lauren A

2017-01-01

We present a supervised machine learning approach to the inversion of Fredholm integrals of the first kind as they arise, for example, in the analytic continuation problem of quantum many-body physics. The approach provides a natural regularization for the ill-conditioned inverse of the Fredholm kernel, as well as an efficient and stable treatment of constraints. The key observation is that the stability of the forward problem permits the construction of a large database of outputs for physically meaningful inputs. Applying machine learning to this database generates a regression function of controlled complexity, which returns approximate solutions for previously unseen inputs; the approximate solutions are then projected onto the subspace of functions satisfying relevant constraints. Under standard error metrics the method performs as well or better than the Maximum Entropy method for low input noise and is substantially more robust to increased input noise. We suggest that the methodology will be similarly effective for other problems involving a formally ill-conditioned inversion of an integral operator, provided that the forward problem can be efficiently solved.

Zimbabwe faces an acute generalized HIV/AIDS epidemic combined with rapidly deteriorating economic and political conditions, under which levels of domestic violence are on the rise. We aimed to determine possible demographic and behavioral factors associated with physical domestic violence in a rural setting in order to better inform both national and local domestic violence and HIV prevention policies. Using the Project Accept baseline data set, we selected demographic, socio-economic, and behavioral variables that might be associated with physical domestic violence based on a review of the literature. Univariate and multivariate analyses were carried out, and odds ratios (OR) were computed using logistic regression. Women reporting physical domestic violence were significantly more likely to report (i) a history of childhood domestic violence (OR=2.96, Peconomic status as measured by type of homestead (OR=1.4, P=0.04) than women who reported no experience of physical domestic violence. Married women were less likely to experience physical domestic violence than unmarried women (OR=0.65, P=0.011). Women at greatest risk of domestic violence include those with a personal history of violence or sexual abuse, multiple lifetime partners, and low or medium socio-economic status. Risk assessments and joint interventions for both domestic violence reduction and HIV prevention should target these population groups, which are effective both on the public health and global heath diplomacy levels.

Experimental plasma research project summaries

International Nuclear Information System (INIS)

1992-06-01

This is the latest in a series of Project Summary books going back to 1976 and is the first after a hiatus of several years. They are published to provide a short description of each project supported by the Experimental Plasma Research Branch of the Division of Applied Plasma Physics in the Office of Fusion Energy. The Experimental Plasma Research Branch seeks to provide a broad range of experimental data, physics understanding, and new experimental techniques that contribute to operation, interpretation, and improvement of high temperature plasma as a source of fusion energy. In pursuit of these objectives, the branch supports research at universities, DOE laboratories, other federal laboratories and industry. About 70 percent of the funds expended are spent at universities and a significant function of this program is the training of students in fusion physics. The branch supports small- and medium-scale experimental studies directly related to specific critical plasma issues of the magnetic fusion program. Plasma physics experiments are conducted on transport of particles and energy within plasma and innovative approaches for operating, controlling, and heating plasma are evaluated for application to the larger confinement devices of the magnetic fusion program. New diagnostic approaches to measuring the properties of high temperature plasmas are developed to the point where they can be applied with confidence on the large-scale confinement experiments. Atomic data necessary for impurity control, interpretation of diagnostic data, development of heating devices, and analysis of cooling by impurity ion radiation are obtained. The project summaries are grouped into these three categories of plasma physics, diagnostic development and atomic physics

`I'm doing a physics that is pulling me towards it.' `I like the course being more up to date.' `You learn the physics but you also think ``well I actually see a point in knowing this physics''.' `This course presents physics in a more interesting way as it focuses on practical activity and applications of physics.' `The industrial visit gives students the opportunity to look for science in action.' These are just some of the comments from students and teachers piloting the new Salters Horners Advanced Physics course (SHAP). Contexts and applications drive the course, providing interest and motivation for students and alerting them to some of the many career areas that involve physics. For example, the operation of a CD player leads to a study of waves and superposition; archaeological surveying and analysis brings in d.c. circuitry and x-ray diffraction; consideration of safety in rail transport involves learning about mechanics and electromagnetism. The course is produced by a team directed from the University of York and funded by a consortium of industrial and charitable sponsors. It is examined by Edexcel and support materials are published by Heinemann. The pilot, involving some 50 centres, began in September 1998 with the new subject core and the AS qualification intermediate between GCSE and the full A-level standard. The course has been fully approved by QCA, and from September 2000 it will be open to all. For comprehensive information about SHAP, visit the project's website: www.york.ac.uk/org/seg/salters/physics . Pilot materials for students, teachers and technicians are available from Heinemann. They will be re-edited and published in full colour for September 2000. Members of the team will attend the annual ASE meeting in Leeds this month; there will be a talk and a hands-on workshop where student activities can be sampled. Materials will be on view at the University of York stand. In addition, Edexcel and the York team are running a series of

As automotive fuel economy requirements increase, the push for reducing overall vehicle weight will likely include the consideration of materials that have not previously been part of mainstream vehicle design and manufacturing, including carbon fiber composites. Vehicle manufacturers currently rely on computer-aided engineering (CAE) methods as part of the design and development process, so going forward, the ability to accurately and predictably model carbon fiber composites will be necessary. If composites are to be used for structural components, this need applies to both, crash and quasi-static modeling. This final report covers the results of a five-year, $6.89M, 50% cost-shared research project between Department of Energy (DOE) and the US Advanced Materials Partnership (USAMP) under Cooperative Agreement DE-EE-0005661 known as “Validation of Material Models for Automotive Carbon Fiber Composite Structures Via Physical and Crash Testing (VMM).” The objective of the VMM Composites Project was to validate and assess the ability of physics-based material models to predict crash performance of automotive primary load-carrying carbon fiber composite structures. Simulation material models that were evaluated included micro-mechanics based meso-scale models developed by the University of Michigan (UM) and micro-plane models by Northwestern University (NWU) under previous collaborations with the DOE and Automotive Composites Consortium/USAMP, as well as five commercial crash codes: LS-DYNA, RADIOSS, VPS/PAM-CRASH, Abaqus, and GENOA-MCQ. CAE predictions obtained from seven organizations were compared with experimental results from quasi-static testing and dynamic crash testing of a thermoset carbon fiber composite front-bumper and crush-can (FBCC) system gathered under multiple loading conditions. This FBCC design was developed to demonstrate progressive crush, virtual simulation, tooling, fabrication, assembly, non-destructive evaluation and crash testing

Robinson, S.J.; Faust, H.; Piotrowski, A.E.

1996-05-01

This report summarizes work carried out during the period 1991-1995 in connection with the refinement of the concepts and detailed designs for nuclear and fundamental physics research instrumentation at the proposed Advanced Neutron source at Oak Ridge National Laboratory. Initially, emphasis was placed on refining the existing System Design Document (SDD-43) to detail more accurately the needs and interfaces of the instruments that are identified in the document. The conceptual designs of these instruments were also refined to reflect current thinking in the field of nuclear and fundamental physics. In particular, the on-line isotope separator (ISOL) facility design was reconsidered in the light of the development of interest in radioactive ion beams within the nuclear physics community. The second stage of this work was to define those instrument parameters that would interface directly with the reactor systems so that these parameters could be considered for the ISOL facility and particularly for its associated ion source. Since two of these options involved ion sources internal to the long slant beam tube, these were studied in detail. In addition, preliminary work was done to identify the needs for the target holder and changing facility to be located in the tangential through-tube. Because many of the planned nuclear and fundamental physics instruments have similar needs in terms of detection apparatus, some progress was also made in defining the parameters for these detectors. 21 refs., 32 figs., 2 tabs

Fleming, Quentin W

2010-01-01

Organizations that follow the principles of good Earned Value Management (EVM) create an environment that allows teams to successfully operate and thrive ? even in the face of challenges that could negatively impact their projects. Earned Value Project Management (EVPM) is a methodology used to measure and communicate the real physical progress of a project taking into account the work completed, the time taken and the costs incurred to complete that work. As a result, EVPM allows more educated and effective management decision-making, which helps evaluate and control project risk by measuring project progress in monetary terms. In the first two editions of Earned Value Project Management, Quentin W. Fleming and Joel M. Koppelman provided guidance for project management practitioners already familiar with EVPM, was well as those who were new to the use of this technique. The third edition expanded the information available on of EVPM for medium and smaller projects while still being relevant for larger projec...

Full Text Available Abstract Background This paper describes Project FIT, a collaboration between the public school system, local health systems, physicians, neighborhood associations, businesses, faith-based leaders, community agencies and university researchers to develop a multi-faceted approach to promote physical activity and healthy eating toward the general goal of preventing and reducing childhood obesity among children in Grand Rapids, MI, USA. Methods/design There are four overall components to Project FIT: school, community, social marketing, and school staff wellness - all that focus on: 1 increasing access to safe and affordable physical activity and nutrition education opportunities in the schools and surrounding neighborhoods; 2 improving the affordability and availability of nutritious food in the neighborhoods surrounding the schools; 3 improving the knowledge, self-efficacy, attitudes and behaviors regarding nutrition and physical activity among school staff, parents and students; 4 impacting the 'culture' of the schools and neighborhoods to incorporate healthful values; and 5 encouraging dialogue among all community partners to leverage existing programs and introduce new ones. Discussion At baseline, there was generally low physical activity (70% do not meet recommendation of 60 minutes per day, excessive screen time (75% do not meet recommendation of rd-5th grade children (n = 403.

This project had two major goals. Final Goal: obtain spectrally resolved, absolutely calibrated x-ray emission data from uniquely uniform mm-scale near-critical-density high-Z plasmas not in local thermodynamic equilibrium (LTE) to benchmark modern detailed atomic physics models. Scientific significance: advance understanding of non-LTE atomic physics. Intermediate Goal: develop new nano-fabrication techniques to make suitable laser targets that form the required highly uniform non-LTE plasmas when illuminated by high-intensity laser light. Scientific significance: advance understanding of nano-science. The new knowledge will allow us to make x-ray sources that are bright at the photon energies of most interest for testing radiation hardening technologies, the spectral energy range where current x-ray sources are weak. All project goals were met.

[The CHILT I project (Children's Health Interventional Trial). A multicomponent intervention to prevent physical inactivity and overweight in primary schools].

Graf, C; Dordel, S

2011-03-01

Child and juvenile obesity is increasing worldwide; therefore, effective preventive strategies are warranted. The stepwise project CHILT (Children's Health Interventional Trial) was initiated in 2000 and combines in its multicomponent school-based arm CHILT I health education and physical activity for primary school children to prevent physical inactivity and overweight. The effect on obesity and physical performance was studied in 12 primary schools (intervention schools, IS) compared with 5 control schools (CS). Anthropometric data were recorded. Physical performance was measured by a coordination test for children (the "Körperkoordinationstest für Kinder", KTK) and the 6-minute run. Anthropometric and motoric data of 436 children in IS (55.0% of the population) and 179 children in CS (62.8%) were available at baseline and at follow-up. No difference in the incidence of overweight was found between the IS and CS after 4 years of intervention. Remission of overweight was higher in IS (23.2% versus 19.2%), but not significant. The increase in BMI was significantly lower in IS, in which the program was regularly performed. There was an improvement in selected items of the KTK in IS. In particular, endurance performance tended to be higher at final examination. School-based preventive intervention seems to have a positive influence on physical motor skills and the remission of overweight. To optimize the effects, a consistent and quality assured implementation and the integration of the children's whole environment are warranted.

Physical activity has positive effects on cancer patients. Dancing addresses diverse bio-psycho-social aspects. Our aim was to assess the evidence on ballroom dancing and to develop the setting for a pilot project. We performed a systematic review, extracted the data and designed a pilot training based on standard curricula. We included cancer patients during or after therapy. Training duration was 90 min with one regular pause and individual pauses as needed. We retrieved two systematic reviews and six controlled studies. Types of dancing varied. Only one study used ballroom dancing. Dance training might improve well-being, physical fitness, fatigue and coping during and after therapy. Yet, evidence is scarce and data to derive the effect size are lacking; 27 patients and their partners took part in the pilot training. Patients and partners needed more time to learn the steps than is planned in regular ballroom classes. Participants were very satisfied with the adaptation of the training to their physical strength and estimated the training in a sheltered group. No side effects occurred. In spite of a high rate of participants reporting fatigue, 90 min of physical activity with only a few minutes of rest were manageable for all participants. Ballroom dancing may offer benefits for patients with respect to quality of life. Cancer patients prefer sheltered training setting and curricula of regular ballroom classes must be adapted for cancer patients. Strict curricula might reduce motivation and adherence and exclude patients with lower or variable fitness.

We use single-dish radio spectra of known 22 GHz H{sub 2}O megamasers, primarily gathered from the large data set observed by the Megamaser Cosmology Project, to identify Keplerian accretion disks and to investigate several aspects of the disk physics. We test a mechanism for maser excitation proposed by Maoz and McKee (1998), whereby population inversion arises in gas behind spiral shocks traveling through the disk. Though the flux of redshifted features is larger on average than that of blueshifted features, in support of the model, the high-velocity features show none of the predicted systematic velocity drifts. We find rapid intra-day variability in the maser spectrum of ESO 558−G009 that is likely the result of interstellar scintillation, for which we favor a nearby (D ≈ 70 pc) scattering screen. In a search for reverberation in six well-sampled sources, we find that any radially propagating signal must be contributing ≲10% of the total variability. We also set limits on the magnetic field strengths in seven sources, using strong flaring events to check for the presence of Zeeman splitting. These limits are typically 200–300 mG (1σ), but our most stringent limits reach down to 73 mG for the galaxy NGC 1194.

Pre-test data and lessons learned from a group research project examining changes in physical activity behavior following construction of a rails-to-trails facility.

Built environments in rural settings may provide greater challenges than those in urban settings due to physical characteristics inherent to low-density population areas. Multiuse recreational trails, such as those that repurpose abandoned railroad lines, may provide a physical activity resource that is well suited to rural areas. However, the direct impact of trail availability on physical activity behavior is not generally known because it is unclear whether activity reported in most trail research represents increases in physical activity or displacement of activity in individuals who previously exercised in other locations. This research, initiated by a group of students in a graduate seminar, represents to our knowledge, the first instance in which PA was assessed prior to the availability of an entirely new rails-to-trails facility. The research was implemented using a nonequivalent dependent variable design to counter the lack of a control group; the nonequivalent dependent variable chosen was weekly servings of fruit and vegetables. Participants responding to intercept interviews classified days of activity during the prior week as mild, moderate or vigorous. Baseline results for 244 participants suggested generally low levels of activity prior to trail availability; number of reported days of activity decreased with described intensity. We also discuss several issues encountered in planning and implementing this group project including those related to data collection, variable levels of commitment among student members, and inconsistent project management, and offer potential solutions to these concerns.

Project Energize, a multicomponent through-school physical activity and nutrition programme, is delivered to all primary school children in the Waikato region. The programme aim is to improve the overall health and reduce the rate of weight gain of all Waikato primary school children. An existing economic model was used to extrapolate the programme effects, initial costs, lifetime health treatment cost structures, quality-adjusted-life-years gained and increased life expectancy to the general and Māori child population of New Zealand. In March 2011, a sample of 2474 younger (7.58 ± 0.57 years, mean ± SD) and 2330 older (10.30 ± 0.51 years) children (36% Māori) attending Energize schools had body mass index measured and compared using mixed effect modelling with unEnergized comparison children from 2004 and 2006 from the same region. In 2011 the median body mass index reduction compared with the comparison younger children was -0.504 (90% CI -0.435 to -0.663) kg/m(2) and in the older children -0.551 (-0.456 to -0.789) kg/m(2). In 2010 there were 42,067 children attending Energize schools and in the same year NZ$1,891,175 was spent to deliver the programme; a cost of $44.96/child/year. Compared to the comparison children the increment in cost/quality-adjusted-life-year gained was $30,438 for the younger and $24,690 for the older children, and lower for Māori (younger $28,241, older $22,151) and for the middle socioeconomic status schools ($23,211, $17,891). Project Energize would improve quality and length of life and when compared with other obesity prevention programmes previously assessed with this model, it would be relatively cost-effective from the health treatment payer's perspective.

Physics of intense, high energy radiation effects

2011-01-01

This document summarizes the work done in our three-year LDRD project titled 'Physics of Intense, High Energy Radiation Effects.' This LDRD is focused on electrical effects of ionizing radiation at high dose-rates. One major thrust throughout the project has been the radiation-induced conductivity (RIC) produced by the ionizing radiation. Another important consideration has been the electrical effect of dose-enhanced radiation. This transient effect can produce an electromagnetic pulse (EMP). The unifying theme of the project has been the dielectric function. This quantity contains much of the physics covered in this project. For example, the work on transient electrical effects in radiation-induced conductivity (RIC) has been a key focus for the work on the EMP effects. This physics in contained in the dielectric function, which can also be expressed as a conductivity. The transient defects created during a radiation event are also contained, in principle. The energy loss lead the hot electrons and holes is given by the stopping power of ionizing radiation. This information is given by the inverse dielectric function. Finally, the short time atomistic phenomena caused by ionizing radiation can also be considered to be contained within the dielectric function. During the LDRD, meetings about the work were held every week. These discussions involved theorists, experimentalists and engineers. These discussions branched out into the work done in other projects. For example, the work on EMP effects had influence on another project focused on such phenomena in gases. Furthermore, the physics of radiation detectors and radiation dosimeters was often discussed, and these discussions had impact on related projects. Some LDRD-related documents are now stored on a sharepoint site (https://sharepoint.sandia.gov/sites/LDRD-REMS/default.aspx). In the remainder of this document the work is described in catergories but there is much overlap between the atomistic calculations, the

We examined the association between physical function and the risk for reported elder abuse. In the Chicago Health and Aging Project (N = 8,932), 238 participants had reported elder abuse. The independent variable was objectively assessed physical function using both directly observed physical performance testing and self-reported physical function (Katz activity of daily living scale, Nagi physical activity scale, and Rosow Breslau mobility scales). Outcomes were elder abuse and specific subtypes of elder abuse. After adjusting for confounders, lower levels of physical performance testing (OR, 2.71[1.58-4.64]), Katz impairment (OR, 1.84[1.29-2.59]), Nagi impairment (OR, 1.65[1.15-2.37]) and Rosow Breslau (OR, 1.76[1.26-2.47]) were associated with increased risk for elder abuse. Lowest levels of physical performance testing were associated with increased risk for psychological abuse (OR, 2.69[1.27-5.71]), caregiver neglect (OR, 2.66[1.22-5.79]), and financial exploitation (OR, 2.35 [1.21-4.55]). Our results may have important implications to healthcare professional, social services and other disciplines to prevent and treat elder abuse. © The Author(s) 2012.

A major accomplishment of this project in the past year is the completion of a fairly comprehensive paper describing the survey of radiative capture reactions of protons on light nuclei at low energies. In addition we have completed a preliminary set of measurements of (d,p)/(d,α) cross section ratios on the charge symmetric nuclei 6 Li and 10 B as a test of the Oppenheimer-Phillips effect. While the 6 Li data remain inconclusive, the 10 B data show solid evidence for the Oppenheimer-Phillips enhancement of the (d,p) reaction relative to the (d,α) reaction for deuteron bombarding energies below about 100 keV. We have continued our investigation of fusion reaction products from deuterium-metal systems at room temperatures with the startling observation of intense burst of energetic charged particles from deuterium gas loaded thin titaium foils subject to non-equilibrium thermal and electrical conditions. We have completed two projects involving the application of the low energy particle accelerator to material science problems; firstly a study of the transformation of crystalline to amorphous Fe-Zr systems by proton irradiation and secondly the effects of ion bombardment on the critical temperature of YBCO high-temperature superconductors. Finally we have made progress in several instrumentation projects which will be used in some of the up-coming measurements of nuclear cross sections at very low energies

Department of Physics' Involvement of the Impact Testing Project of the High Speed Civil Transport Program (HSCT)

Science.gov (United States)

VonMeerwall, Ernst D.

1994-01-01

The project involved the impact testing of a kevlar-like woven polymer material, PBO. The purpose was to determine whether this material showed any promise as a lightweight replacement material for jet engine fan containment. The currently used metal fan containment designs carry a high drag penalty due to their weight. Projectiles were fired at samples of PBO by means of a 0.5 inch diameter Helium powered gun. The Initial plan was to encase the samples inside a purpose-built steel "hot box" for heating and ricochet containment. The research associate's responsibility was to develop the data acquisition programs and techniques necessary to determine accurately the impacting projectile's velocity. Beyond this, the Research Associate's duties include any physical computations, experimental design, and data analysis necessary.

We aimed (1) to report age-specific physical fitness levels in people with fibromyalgia of a representative sample from Andalusia; and (2) to compare the fitness levels of people with fibromyalgia with non-fibromyalgia controls. This cross-sectional study included 468 (21 men) patients with fibromyalgia and 360 (55 men) controls. The fibromyalgia sample was geographically representative from southern Spain. Physical fitness was assessed with the Senior Fitness Test battery plus the handgrip test. We applied the Generalized Additive Model for Location, Scale and Shape to calculate percentile curves for women and fitted mean curves using a linear regression for men. Our results show that people with fibromyalgia reached worse performance in all fitness tests than controls (P fitness levels among patients with fibromyalgia and controls in a large sample of patients with fibromyalgia from southern of Spain. Physical fitness levels of people with fibromyalgia from Andalusia are very low in comparison with age-matched healthy controls.

Theory of Abelian projection

International Nuclear Information System (INIS)

Ogilvie, M.C.

1999-01-01

Analytic methods for Abelian projection are developed. A number of results are obtained related to string tension measurements. It is proven that even without gauge fixing, Abelian projection yields string tensions of the underlying non-Abelian theory. Strong arguments are given for similar results in the case where gauge fixing is employed. The methods used emphasize that the projected theory is derived from the underlying non-Abelian theory rather than vice versa. In general, the choice of subgroup used for projection is not very important, and need not be Abelian. While gauge fixing is shown to be in principle unnecessary for the success of Abelian projection, it is computationally advantageous for the same reasons that improved operators, e.g., the use of fat links, are advantageous in Wilson loop measurements. Two other issues, Casimir scaling and the conflict between projection and critical universality, are also discussed. copyright 1999 The American Physical Society

Effective Physics Study Habits

Zettili, Nouredine

2011-04-01

We discuss the methods of efficient study habits and how they can be used by students to help them improve learning physics. In particular, we deal with ideas pertaining to the most effective techniques needed to help students improve their physics study skills. These ideas were developed as part of Project IMPACTSEED (IMproving Physics And Chemistry Teaching in SEcondary Education), an outreach grant funded by the Alabama Commission on Higher Education. This project is motivated by a major pressing local need: A large number of high school physics teachers teach out of field. In the presentation, focus on topics such as the skills of how to develop long term memory, how to improve concentration power, how to take class notes, how to prepare for and take exams, how to study scientific subjects such as physics. We argue that the student who conscientiously uses the methods of efficient study habits will be able to achieve higher results than the student who does not; moreover, a student equipped with the proper study skills will spend much less time to learn a subject than a student who has no good study habits. The underlying issue here is not the quantity of time allocated to the study efforts by the student, but the efficiency and quality of actions. This work is supported by the Alabama Commission on Higher Education as part of IMPACTSEED grant.

Full Text Available Understanding the mechanisms of increasing the number of physics teachers educated per year at institutions with thriving physics teacher preparation programs may inspire and support other institutions in building thriving programs of their own. The Physics Teacher Education Coalition (PhysTEC, led by the American Physical Society (APS and the American Association of Physics Teachers (AAPT, has supported transformation of physics teacher preparation programs at a number of institutions around the country for over a decade. In 2012–2013, PhysTEC supported an independent study on the sustainability of its sites after project funding ends. The study sought to measure the extent to which programs have been sustained and to identify what features should be prioritized for building sustainable physics teacher preparation programs. Most of the studied sites have sustained increases in the number of physics teachers educated per year as well as funding for physics teacher preparation. About half of the programs are thriving, in that in the post-award period, they have further increased both the number of physics teachers educated per year and funding for physics teacher preparation. All studied sites that sustained increases in the number of physics teachers educated per year have two features in common: a champion of physics teacher education and institutional commitment. The thriving physics teacher preparation programs in this study implemented different elements of physics teacher preparation according to diverse local priorities and opportunities, including the unique expertise of local personnel.

Only one-third of the European population meets the minimum recommended levels of physical activity (PA). Physical inactivity is a major risk factor for non-communicable diseases. Walking and cycling for transport (active mobility, AM) are well suited to provide regular PA. The European research project Physical Activity through Sustainable Transport Approaches (PASTA) pursues the following aims: (1) to investigate correlates and interrelations of AM, PA, air pollution and crash risk; (2) to evaluate the effectiveness of selected interventions to promote AM; (3) to improve health impact assessment (HIA) of AM; (4) to foster the exchange between the disciplines of public health and transport planning, and between research and practice. PASTA pursues a mixed-method and multilevel approach that is consistently applied in seven case study cities. Determinants of AM and the evaluation of measures to increase AM are investigated through a large scale longitudinal survey, with overall 14,000 respondents participating in Antwerp, Barcelona, London, Örebro, Rome, Vienna and Zurich. Contextual factors are systematically gathered in each city. PASTA generates empirical findings to improve HIA for AM, for example, with estimates of crash risks, factors on AM-PA substitution and carbon emissions savings from mode shifts. Findings from PASTA will inform WHO's online Health Economic Assessment Tool on the health benefits from cycling and/or walking. The study's wide scope, the combination of qualitative and quantitative methods and health and transport methods, the innovative survey design, the general and city-specific analyses, and the transdisciplinary composition of the consortium and the wider network of partners promise highly relevant insights for research and practice. Ethics approval has been obtained by the local ethics committees in the countries where the work is being conducted, and sent to the European Commission before the start of the survey.

Schult, Tamara M; Schmunk, Sandra K; Awosika, Ebi R

2016-12-01

The aim of this study was to describe a comprehensive approach to decrease physical inactivity in the Veterans Health Administration (VHA) employee population. The approach included (1) initiatives to decrease physical inactivity in the workplace; (2) two operational surveys to assess system-wide service provision; and (3) two national employee surveys. From 2010 to 2012, 86 employee fitness centers were completed in VA medical centers. A grants program (2010 to 2015) funded smaller projects designed to decrease physical inactivity in the workplace. Projects involved the provision of equipment to decrease sedentary behaviors, including stability balls, treadmill and sit-to-stand desks, stairwell projects, and funding for on-site fitness classes, bicycle racks, and outdoor par courses and walking paths among others. A comprehensive approach to decrease physical inactivity in VHA employees was successful. Overall, self-reported, age-adjusted physical inactivity in VHA employees decreased from 25.3% in 2010 to 16.1% in 2015.

Configuration management is designed as a project management tool to determine and control baselines, and ensure and document all components of a project interface both physically and functionally. The purpose is to ensure that the product acquired satisfies the project's technical and operational requirements, and that the technical requirements are clearly defined and controlled throughout the development and acquisition process. 5 figs

Physics of intense, high energy radiation effects.

2011-02-01

This document summarizes the work done in our three-year LDRD project titled 'Physics of Intense, High Energy Radiation Effects.' This LDRD is focused on electrical effects of ionizing radiation at high dose-rates. One major thrust throughout the project has been the radiation-induced conductivity (RIC) produced by the ionizing radiation. Another important consideration has been the electrical effect of dose-enhanced radiation. This transient effect can produce an electromagnetic pulse (EMP). The unifying theme of the project has been the dielectric function. This quantity contains much of the physics covered in this project. For example, the work on transient electrical effects in radiation-induced conductivity (RIC) has been a key focus for the work on the EMP effects. This physics in contained in the dielectric function, which can also be expressed as a conductivity. The transient defects created during a radiation event are also contained, in principle. The energy loss lead the hot electrons and holes is given by the stopping power of ionizing radiation. This information is given by the inverse dielectric function. Finally, the short time atomistic phenomena caused by ionizing radiation can also be considered to be contained within the dielectric function. During the LDRD, meetings about the work were held every week. These discussions involved theorists, experimentalists and engineers. These discussions branched out into the work done in other projects. For example, the work on EMP effects had influence on another project focused on such phenomena in gases. Furthermore, the physics of radiation detectors and radiation dosimeters was often discussed, and these discussions had impact on related projects. Some LDRD-related documents are now stored on a sharepoint site (https://sharepoint.sandia.gov/sites/LDRD-REMS/default.aspx). In the remainder of this document the work is described in catergories but there is much overlap between the atomistic

The Salton Sea Scientific Drilling Project, was spudded on 24 October 1985, and reached a total depth of 10,564 ft. (3. 2 km) on 17 March 1986. There followed a period of logging, a flow test, and downhole scientific measurements. The scientific goals were integrated smoothly with the engineering and economic objectives of the program and the ideal of 'science driving the drill' in continental scientific drilling projects was achieved in large measure. The principal scientific goals of the project were to study the physical and chemical processes involved in an active, magmatically driven hydrothermal system. To facilitate these studies, high priority was attached to four areas of sample and data collection, namely: (1) core and cuttings, (2) formation fluids, (3) geophysical logging, and (4) downhole physical measurements, particularly temperatures and pressures.

Risk factors for physical domestic violence in a high-prevalence HIV setting: findings from Project Accept baseline data (HPTN-043

Full Text Available Zimbabwe faces an acute generalized HIV/AIDS epidemic combined with rapidly deteriorating economic and political conditions, under which levels of domestic violence are on the rise. We aimed to determine possible demographic and behavioral factors associated with physical domestic violence in a rural setting in order to better inform both national and local domestic violence and HIV prevention policies. Using the Project Accept baseline data set, we selected demographic, socio-economic, and behavioral variables that might be associated with physical domestic violence based on a review of the literature. Univariate and multivariate analyses were carried out, and odds ratios (OR were computed using logistic regression. Women reporting physical domestic violence were significantly more likely to report (i a history of childhood domestic violence (OR=2.96, P<0.001, (ii two or more lifetime partners (OR=1.94, P<0.001, (iii some form of sexual abuse as a child (OR=1.82, not significant, and (iv low or medium socio-economic status as measured by type of homestead (OR=1.4, P=0.04 than women who reported no experience of physical domestic violence. Married women were less likely to experience physical domestic violence than unmarried women (OR=0.65, P=0.011. Women at greatest risk of domestic violence include those with a personal history of violence or sexual abuse, multiple lifetime partners, and low or medium socio-economic status. Risk assessments and joint interventions for both domestic violence reduction and HIV prevention should target these population groups, which are effective both on the public health and global heath diplomacy levels.

After physics

Albert, David Z

2015-01-01

After Physics presents ambitious new essays about some of the deepest questions at the foundations of physics, by the physicist and philosopher David Albert. The book’s title alludes to the close connections between physics and metaphysics, much in evidence throughout these essays. It also alludes to the work of imagining what it would be like for the project of physical science—considered as an investigation into the fundamental laws of nature—to be complete. Albert argues that the difference between the past and the future—traditionally regarded as a matter for metaphysical or conceptual or linguistic or phenomenological analysis—can be understood as a mechanical phenomenon of nature. In another essay he contends that all versions of quantum mechanics that are compatible with the special theory of relativity make it impossible, even in principle, to present the entirety of what can be said about the world as a narrative sequence of “befores” and “afters.” Any sensible and realistic way of...

Sedentary behavior has been proposed as a risk factor for obesity that is distinct from physical inactivity. This study aimed to examine the association between occupational sedentary behavior and obesity, and to determine if this association is independent of leisure-time physical activity (LTPA). Fully employed participants enrolled between 2001 and 2008 to Alberta's Tomorrow Project, a prospective cohort study in Alberta, Canada, were studied (n = 12,409). Associations between occupational sedentary behavior and waist circumference (WC), waist-to-hip ratio (WHR), and body mass index (BMI) were examined using multiple binary and multinomial logistic regressions. In men, a positive association was observed between daily occupational sedentary hours and WC, WHR, BMI, and with high risk profiles that incorporated both BMI and WC (P < .01). Controlling for vigorous-intensity LTPA in all models strengthened associations between sedentary behavior and measures of obesity. In contrast, inverse associations were observed for occupational sedentary hours and WHR for women (P < .05). In fully employed men, occupational sedentary behavior was positively associated with obesity risk that was not attenuated by physical activity. In women, an increase in obesity risk was not observed with sedentary behavior. Gender differences in the health effects of sedentary behavior require further study.

The FabrIc for Frontier Experiments (FIFE) project is an initiative within the Fermilab Scientific Computing Division designed to steer the computing model for non-LHC Fermilab experiments across multiple physics areas. FIFE is a collaborative effort between experimenters and computing professionals to design and develop integrated computing models for experiments of varying size, needs, and infrastructure. The major focus of the FIFE project is the development, deployment, and integration of solutions for high throughput computing, data management, database access and collaboration management within an experiment. To accomplish this goal, FIFE has developed workflows that utilize Open Science Grid compute sites along with dedicated and commercial cloud resources. The FIFE project has made significant progress integrating into experiment computing operations several services including a common job submission service, software and reference data distribution through CVMFS repositories, flexible and robust data transfer clients, and access to opportunistic resources on the Open Science Grid. The progress with current experiments and plans for expansion with additional projects will be discussed. FIFE has taken the leading role in defining the computing model for Fermilab experiments, aided in the design of experiments beyond those hosted at Fermilab, and will continue to define the future direction of high throughput computing for future physics experiments worldwide.

Purpose: This study's aim was to characterize the nature of students' research conducted for a Master of Science in Physical Therapy (MScPT) degree programme at a Canadian university and evaluate the lead advisors' perspectives of its impact on their research capacity, education, clinical practice, knowledge translation, and health policy. Methods: We conducted a quantitative, cross-sectional, retrospective review of research reports from 2003 to 2014 to characterize the MScPT students' research and a quantitative, cross-sectional e-survey of lead research advisors to evaluate the impact of this research. Results: Data were abstracted from reports of 201 research projects completed between 2003 and 2014. Projects were conducted primarily in university-affiliated hospitals (41.6%) or the university's physical therapy department (41.1%), and the majority (52.5%) had a clinical focus. Of the 95 lead advisors of 201 projects, 59 advisors (response rate 62.1%) of 119 projects completed the survey questionnaire. The respondents most frequently identified clinical practice (45.1%) and advisors' research capacity (31.4%) as areas positively affected by the students' research. Conclusions: The MScPT students' research projects facilitate the conduct of extensive research internally and across affiliated hospitals. This research appears to advance not only clinical practice but also the ability of lead advisors to undertake research.

The ICARUS project aims at the realization of a large-mass, high-sensitivity observatory at the Gran Sasso underground Laboratory for the observation of rare astro-particle reactions, such as the interaction of astrophysical and accelerator neutrinos, and the nucleon decay. The detection technique exploits large-volume Time Projection Chambers filled with liquid Argon (LAr TPC). The general principles of this technique are briefly recalled, together with the milestones in the establishment of the present status. The main focus is given to the realization and tests of the first large-mass (600 ton) detector module, built with fully industrial methods, suitable to be cloned in order to reach the final detector mass of about 3000 ton by 2006.

The Numerical Tokamak Project (NTP) simulation of turbulent transport in the core plasma: A grand challenge in plasma physics

International Nuclear Information System (INIS)

1993-12-01

The long-range goal of the Numerical Tokamak Project (NTP) is the reliable prediction of tokamak performance using physics-based numerical tools describing tokamak physics. The NTP is accomplishing the development of the most advanced particle and extended fluid model's on massively parallel processing (MPP) environments as part of a multi-institutional, multi-disciplinary numerical study of tokamak core fluctuations. The NTP is a continuing focus of the Office of Fusion Energy's theory and computation program. Near-term HPCC work concentrates on developing a predictive numerical description of the core plasma transport in tokamaks driven by low-frequency collective fluctuations. This work addresses one of the greatest intellectual challenges to our understanding of the physics of tokamak performance and needs the most advanced computational resources to progress. We are conducting detailed comparisons of kinetic and fluid numerical models of tokamak turbulence. These comparisons are stimulating the improvement of each and the development of hybrid models which embody aspects of both. The combination of emerging massively parallel processing hardware and algorithmic improvements will result in an estimated 10**2--10**6 performance increase. Development of information processing and visualization tools is accelerating our comparison of computational models to one another, to experimental data, and to analytical theory, providing a bootstrap effect in our understanding of the target physics. The measure of success is the degree to which the experimentally observed scaling of fluctuation-driven transport may be predicted numerically. The NTP is advancing the HPCC Initiative through its state-of-the-art computational work. We are pushing the capability of high performance computing through our efforts which are strongly leveraged by OFE support

Full text: The activities of the Health Physics Laboratory at the Institute of Nuclear Physics (IFJ) in Cracow are principally research in the general area of radiation physics, dosimetry and radiation protection of the employees of the Institute. Theoretical research concerns modelling of radiation effects in radiation detectors and studies of concepts in radiation protection. Experimental research, in the general area of solid state dosimetry, is primarily concerned with thermoluminescence (TL) dosimetry, and more specifically: development of LiF:Mg, Ti, CaF 2 :Tm and CVD diamond detectors for medical applications in conventional and hadron radiotherapy and of LiF:Mg, Cu, P and LiF:Mg, Cu, Si, Na for low-level natural external ionising radiation. Environmental radiation measurements (cosmic-rays on aircraft and radon in dwellings and soil) are also performed using track CR-39 and TLD detectors. The Laboratory provides expert advice on radiation protection regulations at national and international levels. Routine work of the Health Physics Laboratory involves design and maintenance of an in-house developed TL-based personnel dosimetry system for over 200 radiation workers at the INP, supervision of radiation safety on IFJ premises, and advising other INP laboratories on all matters pertaining to radiation safety. We provide personal and environmental TLD dosimetry services for several customers outside the IFJ, mainly in hospitals and nuclear research institutes in Poland. We also calibrate radiation protection instruments (400 per year) for customers in the southern region of Poland. The year 2001 was another eventful year for the Health Physics Laboratory. M. Waligorski has received his Professor of Physics state nomination from A. Kwasniewski, the President of Poland. P. Bilski and M. Budzanowski were granted their Ph.D. degrees by the Scientific Council of the Institute of Nuclear Physics. We continued several national and international research projects. Dr

Physically detached 'compact groups'

Science.gov (United States)

Hernquist, Lars; Katz, Neal; Weinberg, David H.

1995-01-01

A small fraction of galaxies appear to reside in dense compact groups, whose inferred crossing times are much shorter than a Hubble time. These short crossing times have led to considerable disagreement among researchers attempting to deduce the dynamical state of these systems. In this paper, we suggest that many of the observed groups are not physically bound but are chance projections of galaxies well separated along the line of sight. Unlike earlier similar proposals, ours does not require that the galaxies in the compact group be members of a more diffuse, but physically bound entity. The probability of physically separated galaxies projecting into an apparent compact group is nonnegligible if most galaxies are distributed in thin filaments. We illustrate this general point with a specific example: a simulation of a cold dark matter universe, in which hydrodynamic effects are included to identify galaxies. The simulated galaxy distribution is filamentary and end-on views of these filaments produce apparent galaxy associations that have sizes and velocity dispersions similar to those of observed compact groups. The frequency of such projections is sufficient, in principle, to explain the observed space density of groups in the Hickson catalog. We discuss the implications of our proposal for the formation and evolution of groups and elliptical galaxies. The proposal can be tested by using redshift-independent distance estimators to measure the line-of-sight spatial extent of nearby compact groups.

CERN, ESA and ESO Put Physics On Stage [1] Summary Can you imagine how much physics is in a simple match of ping-pong, in throwing a boomerang, or in a musical concert? Physics is all around us and governs our lives. The World-Wide Web and mobile communication are only two examples of technologies that have rapidly found their way from science into the everyday life. [Go to Physics On Stage Website at CERN] But who is going to maintain these technologies and develop new ones in the future? Probably not young Europeans, as recent surveys show a frightening decline of interest in physics and technology among Europe's citizens, especially schoolchildren. Fewer and fewer young people enrol in physics courses at university. The project "Physics on Stage" tackles this problem head on. An international festival of 400 physics educators from 22 European countries [2] gather at CERN in Geneva from 6 to 10 November to show how fascinating and entertaining physics can be . In a week-long event innovative methods of teaching physics and demonstrations of the fun that lies in physics are presented in a fair, in 10 spectacular performances, and presentations. Workshops on 14 key themes will give the delegates - teachers, professors, artists and other physics educators - the chance to discuss and come up with solutions for the worrying situation of disenchantment with Science in Europe. The European Science and Technology Week 2000 "Physics on Stage" is a joint project organised by the European Organisation for Nuclear Research (CERN) , the European Space Agency (ESA) and the European Southern Observatory (ESO) , Europe's leading physics research organisations. This is the first time that these three organisations have worked together in such close collaboration to catalyse a change in attitude towards science and technology education. Physics on Stage is funded in part by the European Commission and happens as an event in the European Science and Technology Week 2000, an

Projected coupled cluster theory.

Science.gov (United States)

Qiu, Yiheng; Henderson, Thomas M; Zhao, Jinmo; Scuseria, Gustavo E

2017-08-14

Coupled cluster theory is the method of choice for weakly correlated systems. But in the strongly correlated regime, it faces a symmetry dilemma, where it either completely fails to describe the system or has to artificially break certain symmetries. On the other hand, projected Hartree-Fock theory captures the essential physics of many kinds of strong correlations via symmetry breaking and restoration. In this work, we combine and try to retain the merits of these two methods by applying symmetry projection to broken symmetry coupled cluster wave functions. The non-orthogonal nature of states resulting from the application of symmetry projection operators furnishes particle-hole excitations to all orders, thus creating an obstacle for the exact evaluation of overlaps. Here we provide a solution via a disentanglement framework theory that can be approximated rigorously and systematically. Results of projected coupled cluster theory are presented for molecules and the Hubbard model, showing that spin projection significantly improves unrestricted coupled cluster theory while restoring good quantum numbers. The energy of projected coupled cluster theory reduces to the unprojected one in the thermodynamic limit, albeit at a much slower rate than projected Hartree-Fock.

Paratte, J.M.

1982-07-01

The LWR-Core behaviour project concerns the mathematical simulation of a light water reactor in normal operation (emergency situations excluded). Computational tools are assembled, i.e. programs and libraries of data. These computational tools can likewise be used in nuclear power applications, industry and control applications. The project is divided into three parts: the development and application of calculation methods for quantisation determination of LWR physics; investigation of the behaviour of nuclear fuels under radiation with special attention to higher burnup; simulation of the operating transients of nuclear power stations.

The core activity of the medical physics expert (MPE) is to ensure optimal use of ionising radiation in health care. It is essential that these health care professionals are trained to the highest level, defined as European Qualifications Framework for Lifelong Learning (EQF) level 8 by the European Commission's Radiation Protection Report 174 'Guidelines on the MPE'. The main objective of the EUTEMPE-RX project is to provide a model training scheme that allows the medical physicist in diagnostic and interventional radiology (D and IR) to reach this high level. A European network of partners was brought together in this FP7 EC project to ensure sufficient expertise in all aspects of the subject and to create a harmonised course programme. Targeted participants are medical physicists in D and IR in hospitals, engineers and scientists in medical device industries and officers working in regulatory authorities. Twelve course modules will be developed at EQF level 8, with radiation safety and diagnostic effectiveness being prevalent subjects. The modules will combine online with face-to-face teaching using a blended learning approach. (authors)

EDITORIAL: Student undergraduate laboratory and project work

During the last decade 'labwork' courses at university level have changed significantly. The beginning of this development was indicated and partly initiated by the EU-project 'Labwork in Science Education' funded by the European Community (1999-2001). The present special issue of the European Journal of Physics focuses on a multitude of different aspects of this process. The aim of this publication is to improve the exchange of experience and to promote this important trend. In physics research labs a silent revolution has taken place. Today the personal computer is omnipresent. It controls the experiment via stepping motors, piezo-microdrives etc, it monitors all parameters and collects the experimental data with the help of smart sensors. In particular, computer-based modern scanning and imaging techniques open the possibility of creating really new types of experiments. The computer allows data storage and processing on the one hand and simulation and modelling on the other. These processes occur in parallel or may even be interwoven. The web plays an important role in modern science for inquiry, communication, cooperation and publication. Traditional labwork courses do not prepare students for the many resulting demands. Therefore it is necessary to redefine the learning targets and to reconsider the learning methods. Two contributions show exemplarily how modern experimental devices could find their way into students' labs. In the article 'Infrared thermal imaging as a tool in university physics education' by Klaus-Peter Möllmann and Michael Vollmer we can see that infrared thermal imaging is a valuable tool in physics education at university level. It can help to visualize and thereby enhance understanding of physical phenomena of mechanics, thermal physics, electromagnetism, optics and radiation physics. The contribution 'Using Peltier cells to study solid-liquid-vapor transitions and supercooling' by Giacomo Torzo, Isabella Soletta and Mario Branca proves

This paper describes Project FIT, a collaboration between the public school system, local health systems, physicians, neighborhood associations, businesses, faith-based leaders, community agencies and university researchers to develop a multi-faceted approach to promote physical activity and healthy eating toward the general goal of preventing and reducing childhood obesity among children in Grand Rapids, MI, USA. There are four overall components to Project FIT: school, community, social marketing, and school staff wellness - all that focus on: 1) increasing access to safe and affordable physical activity and nutrition education opportunities in the schools and surrounding neighborhoods; 2) improving the affordability and availability of nutritious food in the neighborhoods surrounding the schools; 3) improving the knowledge, self-efficacy, attitudes and behaviors regarding nutrition and physical activity among school staff, parents and students; 4) impacting the 'culture' of the schools and neighborhoods to incorporate healthful values; and 5) encouraging dialogue among all community partners to leverage existing programs and introduce new ones. At baseline, there was generally low physical activity (70% do not meet recommendation of 60 minutes per day), excessive screen time (75% do not meet recommendation of < 2 hours per day), and low intake of vegetables and whole grains and high intake of sugar-sweetened beverages, French fries and chips and desserts as well as a high prevalence of overweight and obesity (48.5% including 6% with severe obesity) among low income, primarily Hispanic and African American 3rd-5th grade children (n = 403).

Barber, James; Buckley, James

2003-01-01

Fluor Fernald, Inc. (Fluor Fernald), the contractor for the U. S. Department of Energy (DOE) Fernald Environmental Management Project (FEMP), recently submitted a new baseline plan for achieving site closure by the end of calendar year 2006. This plan was submitted at DOE's request, as the FEMP was selected as one of the sites for their accelerated closure initiative. In accordance with the accelerated baseline, the FEMP Waste Management Project (WMP) is actively evaluating innovative processes for the management and disposition of low-level uranium, fissile material, and thorium, all of which have been classified as waste. These activities are being conducted by the Low Level Waste (LLW) and Uranium Waste Disposition (UWD) projects. Alternatives associated with operational processing of individual waste streams, each of which poses potentially unique health physics, industrial hygiene and industrial hazards, are being evaluated for determination of the most cost effective and safe met hod for handling and disposition. Low-level Mixed Waste (LLMW) projects are not addressed in this paper. This paper summarizes historical uranium recycling programs and resultant trace quantity contamination of uranium waste streams with radionuclides, other than uranium. The presentation then describes how waste characterization data is reviewed for radiological and/or chemical hazards and exposure mitigation techniques, in conjunction with proposed operations for handling and disposition. The final part of the presentation consists of an overview of recent operations within LLW and UWD project dispositions, which have been safely completed, and a description of several current operations

Teaching physics using project-based engineering curriculum with a theme of alternative energy

Science.gov (United States)

Tasior, Bryan

The Next Generation Science Standards (NGSS) provide a new set of science standards that, if adopted, shift the focus from content knowledge-based to skill-based education. Students will be expected to use science to investigate the natural world and solve problems using the engineering design process. The world also is facing an impending crisis related to climate, energy supply and use, and alternative energy development. Education has an opportunity to help provide the much needed paradigm shift from our current methods of providing the energy needs of society. The purpose of this research was to measure the effectiveness of a unit that accomplishes the following objectives: uses project-based learning to teach the engineering process and standards of the NGSS, addresses required content expectations of energy and electricity from the HSCE's, and provides students with scientific evidence behind issues (both environmental and social/economic) relating to the energy crisis and current dependence of fossil fuels as our primary energy source. The results of the research indicate that a physics unit can be designed to accomplish these objectives. The unit that was designed, implemented and reported here also shows that it was highly effective at improving students' science content knowledge, implementing the engineering design standards of the NGSS, while raising awareness, knowledge and motivations relating to climate and the energy crisis.

Bangladesh requires 200 radiotherapy facilities, 4 are in use; 400 medical physicists are needed, 3 are employed. On a private basis, a DGMP working group started in 1996, annual workshops on medical physics in cancer diagnosis and treatment, joined by many working physicists interested to become medical physicists. Basic topics were the principles, applications, acceptance, dosimetry and planning of 60 Co radiotherapy. In 1998, the Bangladesh association of physicists in medicine (BMPA) was founded, a young scientific society requiring international co-operation. The long experience in Medical Physics in India, its neighbouring country, could be very helpful in providing excellent medical physics courses. To absorb new technology and science, it is necessary to change the education policy; creativity and innovativeness must be valued more than the old knowledge, being replaced quickly by new knowledge and new technologies.

Outline of J-PARC and development of J-PARC from nuclear physics future plan

International Nuclear Information System (INIS)

Nagamiya, Shoji

2006-01-01

The origin of the Nuclear Physics Future Plan was the NUMATRON project, with which high energy heavy ions were to be accelerated. This project was not successful and another project 'Large Hadron Project' was proposed in 1986 to deliver both of high energy heavy ions and high intensity protons. This project was somewhat modified to build a 1GeV 200μA proton linac in KEK (Institute for High Energy Physics) site to produce pulsed neutrons, pulsed muons and unstable nuclei as a first step to 'Japan Hadron Project'. The linac was expected also to be an injector for KEK 12GeV synchrotron. In 2001 accelerator projects under the Ministry of Education and the Science and Technology Agency were unified to form J-PARC project, which was approved on a chance when the former two government organizations were integrated. J-PARC project aims at performing the materials and life sciences by 3GeV protons, nuclear and elementary particle physics by 50GeV protons and the researches on nuclear transmutation by 0.6GeV protons.

The past, present and future of cyber-physical systems: a focus on models.

Science.gov (United States)

Lee, Edward A

2015-02-26

This paper is about better engineering of cyber-physical systems (CPSs) through better models. Deterministic models have historically proven extremely useful and arguably form the kingpin of the industrial revolution and the digital and information technology revolutions. Key deterministic models that have proven successful include differential equations, synchronous digital logic and single-threaded imperative programs. Cyber-physical systems, however, combine these models in such a way that determinism is not preserved. Two projects show that deterministic CPS models with faithful physical realizations are possible and practical. The first project is PRET, which shows that the timing precision of synchronous digital logic can be practically made available at the software level of abstraction. The second project is Ptides (programming temporally-integrated distributed embedded systems), which shows that deterministic models for distributed cyber-physical systems have practical faithful realizations. These projects are existence proofs that deterministic CPS models are possible and practical.

Remote sensing is defined as data acquisition of an object, deprived physical contact. Fundamentally, most remote sensing applications are referred to as the use of satellite- or aircraft-based sensor technologies to detect and classify objects mainly on Earth or other planets. In the last years there have been efforts to bring the important subject of remote sensing into schools, however, most of these attempts focused on geography disciplines - restricting to the applications of remote sensing and to a less extent the technique itself and the physics behind it. Optical remote sensing is based on physical principles and technical devices, which are very meaningful from a theoretical point of view as well as for "hands-on" teaching. Some main subjects are radiation, atom and molecular physics, spectroscopy, as well as optics and the semiconductor technology used in modern digital cameras. Thus two objectives were outlined for this project: 1) to investigate the possibilities of using remote sensing techniques in physics teaching, and 2) to identify its impact on pupil's interest in the field of natural sciences. This joint project of the DLR_School_Lab, Oberpfaffenhofen of the German Aerospace Center (DLR) and the Earth and Planetary Image Facility (EPIF) at BGU, was conducted in 2016. Thirty teenagers (ages 16-18) participated in the project and were exposed to the cutting edge methods of earth observation. The pupils on both sides participated in the project voluntarily, knowing that at least some of the project's work had to be done in their leisure time. The pupil's project started with a day at EPIF and DLR respectively, where the project task was explained to the participants and an introduction to remote sensing of vegetation was given. This was realized in lectures and in experimental workshops. During the following two months both groups took several measurements with modern optical remote sensing systems in their home region with a special focus on flora

The research programs under the cognizance of the Office of Energy Research (OER) are directed toward discovery of natural laws and new knowledge, and to improved understanding of the physical and biological sciences as related to the development, use, and control of energy. The ultimate goal is to develop a scientific underlay for the overall DOE effort and the fundamental principles of natural phenomena so that these phenomena may be understood, and new principles, formulated. The DOE-OER outlay activities include three major programs: High Energy Physics, Nuclear Physics, and Basic Energy Sciences. Taken together, these programs represent some 30 percent of the Nation's Federal support of basic research in the energy sciences. The research activities of OER involve more than 6,000 scientists and engineers working in some 17 major Federal Research Centers and at more than 135 different universities and industrial firms throughout the United States. Contract holders in the areas of high-energy physics, nuclear physics, materials sciences, nuclear science, chemical sciences, engineering, mathematics geosciences, advanced energy projects, and biological energy research are listed.

Hours spent and energy expended in physical activity domains: Results from The Tomorrow Project cohort in Alberta, Canada

Science.gov (United States)

2011-01-01

Background Knowledge of adult activity patterns across domains of physical activity is essential for the planning of population-based strategies that will increase overall energy expenditure and reduce the risk of obesity and related chronic diseases. We describe domain-specific hours of activity and energy expended among participants in a prospective cohort in Alberta, Canada. Methods The Past Year Total Physical Activity Questionnaire was completed by 15,591 Tomorrow Project® participants, between 2001 and 2005 detailing physical activity type, duration, frequency and intensity. Domain-specific hours of activity and activity-related energy expenditure, expressed as a percent of total energy expenditure (TEE) (Mean (SD); Median (IQR)) are reported across inactive (<1.4), low active (1.4 to 1.59), active (1.6 to 1.89) and very active (≥ 1.9) Physical Activity Level (PAL = TEE:REE) categories. Results In very active women and amongst all men except those classified as inactive, activity-related energy expenditure comprised primarily occupational activity. Amongst inactive men and women in active, low active and inactive groups, activity-related energy expenditure from household activity was comparable to, or exceeded that for occupational activity. Leisure-time activity-related energy expenditure decreased with decreasing PAL categories; however, even amongst the most active men and women it accounted for less than 10 percent of TEE. When stratified by employment status, leisure-time activity-related energy expenditure was greatest for retired men [mean (SD): 10.8 (8.5) percent of TEE], compared with those who were fully employed, employed part-time or not employed. Transportation-related activity was negligible across all categories of PAL and employment status. Conclusion For the inactive portion of this population, active non-leisure activities, specifically in the transportation and occupational domains, need to be considered for inclusion in daily routines

An overview of the human genome project

Energy Technology Data Exchange (ETDEWEB)

Batzer, M.A.

1994-01-01

The human genome project is one of the most ambitious scientific projects to date, with the ultimate goal being a nucleotide sequence for all four billion bases of human DNA. In the process of determining the nucleotide sequence for each base, the location, function, and regulatory regions from the estimated 100,000 human genes will be identified. The genome project itself relies upon maps of the human genetic code derived from several different levels of resolution. Genetic linkage analysis provides a low resolution genome map. The information for genetic linkage maps is derived from the analysis of chromosome specific markers such as Sequence Tagged Sites (STSs), Variable Number of Tandem Repeats (VNTRs) or other polymorphic (highly informative) loci in a number of different-families. Using this information the location of an unknown disease gene can be limited to a region comprised of one million base pairs of DNA or less. After this point, one must construct or have access to a physical map of the region of interest. Physical mapping involves the construction of an ordered overlapping (contiguous) set of recombinant DNA clones. These clones may be derived from a number of different vectors including cosmids, Bacterial Artificial Chromosomes (BACs), P1 derived Artificial Chromosomes (PACs), somatic cell hybrids, or Yeast Artificial Chromosomes (YACs). The ultimate goal for physical mapping is to establish a completely overlapping (contiguous) set of clones for the entire genome. After a gene or region of interest has been localized using physical mapping the nucleotide sequence is determined. The overlap between genetic mapping, physical mapping and DNA sequencing has proven to be a powerful tool for the isolation of disease genes through positional cloning.

Chaos: a topic for interdisciplinary education in physics

International Nuclear Information System (INIS)

Bae, Saebyok

2009-01-01

Since society and science need interdisciplinary works, the interesting topic of chaos is chosen for interdisciplinary education in physics. The educational programme contains various university-level activities such as computer simulations, chaos experiment and team projects besides ordinary teaching. According to the participants, the programme seems useful and good. In addition, we discuss some issues which can be important to interdisciplinary education in physics: for example the possible difficulties in programme design, the expertise barriers of non-major fields, the role of non-theoretical education in understanding and the project-type team activities

Physics potential of the CERN-MEMPHYS neutrino oscillation project

Campagne, J.E.; Maltoni, M.; Mezzetto, M.; Schwetz, T.

2006-03-01

We consider the physics potential of CERN based neutrino oscillation experiments consisting of a Beta Beam (βB) and a Super Beam (SPL) sending neutrinos to MEMPHYS, a 440 kt water Cerenkov detector at Frejus, at a distance of 130 km from CERN. The θ 13 discovery reach and the sensitivity to CP violation are investigated, including a detailed discussion of parameter degeneracies and systematical errors. For βB and SPL sensitivities similar to the ones of the phase II of the T2K experiment (T2HK) are obtained, where the results for the CERN-MEMPHYS experiments are less affected by systematical uncertainties. We point out that by a combination of data from βB and SPL a measurement with antineutrinos is not necessary and hence the same physics results can be obtained within about half of the measurement time compared to one single experiment. Furthermore, it is shown how including data from atmospheric neutrinos in the MEMPHYS detector allows to resolve parameter degeneracies and, in particular, provides sensitivity to the neutrino mass hierarchy and the octant of θ 23 .

2001-01-01

This paper presents the results of a 12-week single-sex, family-based physical activity intervention grounded in Social Cognitive Theory. Mother/daughter pairs and triads (n = 20) attended physical activity and classroom sessions twice weekly. Physiological data (VO2peak, height, and weight), psychological data (physical self-perception profile subscale scores), information about physical activity participation (PAP, d x wk(-1)) and qualitative impressions (QI) of the program were collected pre- and post-intervention. PAP and QI were also collected 6-months after completing the intervention. Although no significant increases in physical activity were reported, significant improvements in perceived sport competence, physical condition, and strength and muscularity were reported over time. The social cognitive theory, as used to plan this physical activity intervention, offered a promising theoretical perspective for facilitating improved physical self-perception in adolescent girls and their mothers.

TCs are typically underprepared for teaching science, and physics in particular. In response to these challenges, we created P4 . P4 is an innovative model for peer learning, creating interdisciplinary partnerships that help college physics instructors train their students in the ``soft skills'' prized in both academia and industry, while helping teacher educators infuse more content knowledge into science methods courses. In P4, PGs plan a lesson and deliver physics content to TCs. TCs then use this content to design and execute a 15-minute elementary science lesson. Framed by the concept of peer learning, we expected P4 would help PGs develop their teaching and communication skills, and TCs learn more physics. We studied the affordances and constraints of P4 to inform future iterations. Overall, P4 was successful, with both PGs and TCs reporting benefits. Affordances for PGs included the chance to plan and teach a class; TCs benefitted from working with experts to increase content knowledge. We will share the full findings and implications of our study, and outline next steps for P4.

Drawing from past experience to improve the management of future underground projects

The high-energy physics community is currently developing plans to build underground facilities as part of its continuing investigation into the fundamental nature of matter. The tunnels and caverns are being designed to house a new generation of particle accelerators and detectors. For these projects, the cost of constructing the underground facility will constitute a major portion of the told capital cost and project viability can be greatly enhanced by paying careful attention to design and construction practices. A review of recently completed underground physics facilities and related literature has been undertaken to identify some management principles that have proven successful in underground practice. Projects reviewed were constructed in the United States of America and Europe using both Design-Build and more traditional Engineer-Procure-Construct contract formats. Although the physics projects reviewed tend to place relatively strict tolerances on alignment, stability and dryness, their overall requirements are similar to those of other tunnels and it is hoped that some of the principles promoted in this paper will be of value to the owner of any underground project

Becoming physics people: Development of integrated physics identity through the Learning Assistant experience

Science.gov (United States)

Close, Eleanor W.; Conn, Jessica; Close, Hunter G.

2016-06-01

[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] In this study, we analyze the experience of students in the Physics Learning Assistant (LA) program at Texas State University in terms of the existing theoretical frameworks of community of practice and physics identity, and explore the implications suggested by these theories for LA program adoption and adaptation. Regression models from physics identity studies show that the physics identity construct strongly predicts intended choice of a career in physics. The goal of our current project is to understand the details of the impacts of participation in the LA experience on participants' practice and self-concept, in order to identify critical elements of LA program structure that positively influence physics identity and physics career intentions for students. Our analysis suggests that participation in the LA program impacts LAs in ways that support both stronger "physics student" identity and stronger "physics instructor" identity, and that these identities are reconciled into a coherent integrated physics identity. Increased comfort in interactions with peers, near peers, and faculty seems to be an important component of this identity development and reconciliation, suggesting that a focus on supporting community membership is useful for effective program design.

After publishing its first strategy plan in 2008, the AStroParticle European Research Area (ASPERA) – a network of European national funding agencies responsible for astroparticle physics – has just published an update. The new document provides an overview of the activities of the astroparticle physics community, makes recommendations for future projects and emphasizes the role of networking and sharing among the funding agencies.   The new strategies for Astroparticle Physics (ApP) – the research field at the intersection of astrophysics, particle physics and cosmology – were discussed at a meeting held in Paris on 21 and 22 November, when a new roadmap was presented to the community. “An update of the strategic plan published in 2008 was needed because of the significant progress made in recent years,” explains Arnaud Marsollier, ASPERA press officer. “In this new roadmap, ASPERA gives an updated overview of ApP Projects ...

Gender differences in introductory university physics performance: The influence of high school physics preparation and affect

Science.gov (United States)

Hazari, Zahra Sana

The attrition of females studying physics after high school is a concern to the science education community. Most undergraduate science programs require introductory physics coursework. Thus, success in introductory physics is necessary for students to progress to higher levels of science study. Success also influences attitudes; if females are well-prepared, feel confident, and do well in introductory physics, they may be inclined to study physics further. This quantitative study using multilevel modeling focused on determining factors from high school physics preparation (content, pedagogy, and assessment) and the affective domain that influenced female and male performance in introductory university physics. The study controlled for some university/course level characteristics as well as student demographic and academic background characteristics. The data consisted of 1973 surveys from 54 introductory physics courses within 35 universities across the US. The results highlight high school physics and affective experiences that differentially influenced female and male performance. These experiences include: learning requirements, computer graphing/analysis, long written problems, everyday world examples, community projects, cumulative tests/quizzes, father's encouragement, family's belief that science leads to a better career, and the length of time students believed that high school physics would help in university physics. There were also experiences that had a similar influence on female and male performance. Positively related to performance were: covering fewer topics for longer periods of time, the history of physics as a recurring topic, physics-related videos, and test/quiz questions that involved calculations and/or were drawn from standardized tests. Negatively related to performance were: student-designed projects, reading/discussing labs the day before performing them, microcomputer based laboratories, discussion after demonstrations, and family

Research into the fundamental nature of matter at the high energy frontier takes place in three main areas: accelerator-based particle physics, high energy astrophysics, and the cosmology of the early universe. As a consequence the study of astroparticle physics can have significant implications for collider physics at the LHC. Likewise, the LHC project provides the laboratory to perform measurements of great importance for cosmic ray astrophysics and cosmology. This paper reviews some of the important synergistic links between astroparticle and LHC physics. (topical review)

Espey, Michael Graham

In 2009, the NCI launched the Physical Sciences - Oncology Centers (PS-OC) initiative with 12 Centers (U54) funded through 2014. The current phase of the Program includes U54 funded Centers with the added feature of soliciting new Physical Science - Oncology Projects (PS-OP) U01 grant applications through 2017; see NCI PAR-15-021. The PS-OPs, individually and along with other PS-OPs and the Physical Sciences-Oncology Centers (PS-OCs), comprise the Physical Sciences-Oncology Network (PS-ON). The foundation of the Physical Sciences-Oncology initiative is a high-risk, high-reward program that promotes a `physical sciences perspective' of cancer and fosters the convergence of physical science and cancer research by forming transdisciplinary teams of physical scientists (e.g., physicists, mathematicians, chemists, engineers, computer scientists) and cancer researchers (e.g., cancer biologists, oncologists, pathologists) who work closely together to advance our understanding of cancer. The collaborative PS-ON structure catalyzes transformative science through increased exchange of people, ideas, and approaches. PS-ON resources are leveraged to fund Trans-Network pilot projects to enable synergy and cross-testing of experimental and/or theoretical concepts. This session will include a brief PS-ON overview followed by a strategic discussion with the APS community to exchange perspectives on the progression of trans-disciplinary physical sciences in cancer research.

Examples from Astronomy for High School Physics

Science.gov (United States)

Dieterich, Sergio

2016-01-01

A formal course in physics is increasingly becoming a standard requirement in the high school curriculum. With that dissemination comes the challenge of reaching and motivating a population that is more diverse in their academic abilities and intrinsic motivation. The abstract nature of pure physics is often made more accessible when motivated by examples from everyday life, and providing copious mathematical as well as conceptual examples has become standard practice in high school physics textbooks. Astronomy is a naturally captivating subject and astronomical examples are often successful in capturing the curiosity of high school students as well as the general population. This project seeks to diversify the range of pedagogical materials available to the high school physics instructor by compiling and publishing specific examples where an astronomical concept can be used to motivate the physics curriculum. This collection of examples will consist of both short problems suitable for daily homework assignments as well as longer project style activities. Collaborations are encouraged and inquiries should be directed to sdieterich at carnegiescience dot edu.This work is funded by the NSF Astronomy and Astrophysics Postdoctoral Fellowship Program through NSF grant AST-1400680.

Plasma simulation studies using multilevel physics models

International Nuclear Information System (INIS)

Park, W.; Belova, E.V.; Fu, G.Y.; Tang, X.Z.; Strauss, H.R.; Sugiyama, L.E.

1999-01-01

The question of how to proceed toward ever more realistic plasma simulation studies using ever increasing computing power is addressed. The answer presented here is the M3D (Multilevel 3D) project, which has developed a code package with a hierarchy of physics levels that resolve increasingly complete subsets of phase-spaces and are thus increasingly more realistic. The rationale for the multilevel physics models is given. Each physics level is described and examples of its application are given. The existing physics levels are fluid models (3D configuration space), namely magnetohydrodynamic (MHD) and two-fluids; and hybrid models, namely gyrokinetic-energetic-particle/MHD (5D energetic particle phase-space), gyrokinetic-particle-ion/fluid-electron (5D ion phase-space), and full-kinetic-particle-ion/fluid-electron level (6D ion phase-space). Resolving electron phase-space (5D or 6D) remains a future project. Phase-space-fluid models are not used in favor of δf particle models. A practical and accurate nonlinear fluid closure for noncollisional plasmas seems not likely in the near future. copyright 1999 American Institute of Physics

De Sitter projective relativity

CERN Document Server

Licata, Ignazio; Benedetto, Elmo

2017-01-01

This book presents the Projective approach to de Sitter Relativity. It traces the development of renewed interest in models of the universe at constant positive curvature such as "vacuum" geometry. The De Sitter Theory of Relativity, formulated in 1917 with Willem De Sitter's solution of the Einstein equations, was used in different fields during the 1950s and 1960s, in the work of H. Bacry, J.M. LevyLeblond and F.Gursey, to name some important contributors. From the 1960s to 1980s, L. Fantappié and G. Arcidiacono provided an elegant group approach to the De Sitter universe putting the basis for special and general projective relativity. Today such suggestions flow into a unitary scenario, and this way the De Sitter Relativity is no more a "missing opportunity" (F. Dyson, 1972), but has a central role in theoretical physics. In this volume a systematic presentation is given of the De Sitter Projective relativity, with the recent developments in projective general relativity and quantum cosmology.

The Past, Present and Future of Cyber-Physical Systems: A Focus on Models

Science.gov (United States)

Lee, Edward A.

2015-01-01

This paper is about better engineering of cyber-physical systems (CPSs) through better models. Deterministic models have historically proven extremely useful and arguably form the kingpin of the industrial revolution and the digital and information technology revolutions. Key deterministic models that have proven successful include differential equations, synchronous digital logic and single-threaded imperative programs. Cyber-physical systems, however, combine these models in such a way that determinism is not preserved. Two projects show that deterministic CPS models with faithful physical realizations are possible and practical. The first project is PRET, which shows that the timing precision of synchronous digital logic can be practically made available at the software level of abstraction. The second project is Ptides (programming temporally-integrated distributed embedded systems), which shows that deterministic models for distributed cyber-physical systems have practical faithful realizations. These projects are existence proofs that deterministic CPS models are possible and practical. PMID:25730486

Some important questions in charmonium physics

International Nuclear Information System (INIS)

Seth, K.

1994-01-01

This paper is devoted to three propositions: (1) Some of the most basic questions in heavy-quark physics remain unanswered; (2) Charmonium physics is the best place to address those questions at the required level of precision; (3) A tau-charm factory, with a commensurate state-of-the-art detector, are mandatory for doing the job. While open-charm and tau physics will certainly be done at beauty factories, charmonium physics will not. It must, therefore, form an important part of the physics program at a tau charm factory. With this as an introduction, the author then reviews the status of charmonium studies at this point, and ongoing work, with its projected weaknesses

This book presents experiments which will teach physics relevant to astronomy. The astronomer, as instructor, frequently faces this need when his college or university has no astronomy department and any astronomy course is taught in the physics department. The physicist, as instructor, will find this intellectually appealing when faced with teaching an introductory astronomy course. From these experiments, the student will acquire important analytical tools, learn physics appropriate to astronomy, and experience instrument calibration and the direct gathering and analysis of data. Experiments that can be performed in one laboratory session as well as semester-long observation projects are included. This textbook is aimed at undergraduate astronomy students.

The Physics Division is organized into three major research areas: Fusion Physics, Weapons Physics, and Basic Research. In Fusion Physics, the KrF laser project reached two important milestones: successful testing of a 1-m 2 electron diode for KrF gas excitation and completion of a combined aperture demonstration showing the feasibility of accurate alignment of spherical mirrors. In the CO 2 program, the 5-kJ Helios lasers were used to evaluate many physics issues concerning the use of 10-μm light for inertial fusion and the 30- to 40-kJ Antares laser construction projects is on schedule for completion in October 1983. In Weapons Physics, significant progress was made on developing continuous time-dependent imaging systems using tomographic techniques with 400-ps shuttering capability, fiber-optic Cerenkov detector systems for fast fusion measurements, and iron-doped indium-phosphide detectors with 70-ps impulse response. A proposal to build x-ray beam lines at the National Synchrotron Light Source was approved and we expect funding in 1984. In Basic Physics Research, we have begun new initiatives to study biomagnetism in collaboration with the Life Sciences Division and to develop a neutrino physics program. During this period numerous significant experiments were completed in our nuclear physics, condensed matter physics, and thermal physics programs

HTGR reactor physics, thermal-hydraulics and depletion uncertainty analysis: a proposed IAEA coordinated research project

International Nuclear Information System (INIS)

Tyobeka, Bismark; Reitsma, Frederik; Ivanov, Kostadin

2011-01-01

The continued development of High Temperature Gas Cooled Reactors (HTGRs) requires verification of HTGR design and safety features with reliable high fidelity physics models and robust, efficient, and accurate codes. The predictive capability of coupled neutronics/thermal hydraulics and depletion simulations for reactor design and safety analysis can be assessed with sensitivity analysis and uncertainty analysis methods. In order to benefit from recent advances in modeling and simulation and the availability of new covariance data (nuclear data uncertainties) extensive sensitivity and uncertainty studies are needed for quantification of the impact of different sources of uncertainties on the design and safety parameters of HTGRs. Uncertainty and sensitivity studies are an essential component of any significant effort in data and simulation improvement. In February 2009, the Technical Working Group on Gas-Cooled Reactors recommended that the proposed IAEA Coordinated Research Project (CRP) on the HTGR Uncertainty Analysis in Modeling be implemented. In the paper the current status and plan are presented. The CRP will also benefit from interactions with the currently ongoing OECD/NEA Light Water Reactor (LWR) UAM benchmark activity by taking into consideration the peculiarities of HTGR designs and simulation requirements.
