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.

To design a new semantically interoperable clinical repository, based on ontologies, conforming to CEN/ISO 13606 standard. The approach followed is to extend OntoCRF, a framework for the development of clinical repositories based on ontologies. The meta-model of OntoCRF has been extended by incorporating an OWL model integrating CEN/ISO 13606, ISO 21090 and SNOMED CT structure. This approach has demonstrated a complete evaluation cycle involving the creation of the meta-model in OWL format, the creation of a simple test application, and the communication of standardized extracts to another organization. Using a CEN/ISO 13606 based system, an indefinite number of archetypes can be merged (and reused) to build new applications. Our approach, based on the use of ontologies, maintains data storage independent of content specification. With this approach, relational technology can be used for storage, maintaining extensibility capabilities. The present work demonstrates that it is possible to build a native CEN/ISO 13606 repository for the storage of clinical data. We have demonstrated semantic interoperability of clinical information using CEN/ISO 13606 extracts. Copyright © 2016 Elsevier Inc. All rights reserved.

THE X-RAY HALO OF CEN X-3

2009-01-01

Using two Chandra observations, we have derived estimates of the dust distribution and distance to the eclipsing high-mass X-ray binary Cen X-3 using the energy-resolved dust-scattered X-ray halo. By comparing the observed X-ray halos in 200 eV bands from 2-5 keV to the halo profiles predicted by the Weingartner and Draine interstellar grain model, we find that the vast majority (∼ 70%) of the dust along the line of sight to the system is located within about 300 pc of the Sun, although the halo measurements are insensitive to dust very close to the source. One of the Chandra observations occurred during an egress from eclipse as the pulsar emerged from behind the mass-donating primary. By comparing model halo light curves during this transition to the halo measurements, a source distance of 5.7 ± 1.5 kpc (68% confidence level) is estimated, although we find this result depends on the distribution of dust on very small scales. Nevertheless, this value is marginally inconsistent with the commonly accepted distance to Cen X-3 of 8 kpc. We also find that the energy scaling of the scattering optical depth predicted by the Weingartner and Draine interstellar grain model does not accurately represent the results determined by X-ray halo studies of Cen X-3. Relative to the model, there appears to be less scattering at low energies or more scattering at high energies in Cen X-3.

Following the tradition, the activities of the seven new units created in 1997 on the basis of the former Department of High Energy Physics are presented under a common header, they are: Department of Particle Theory (Dept 5); Department of Leptonic Interactions (Dept 11); Department of Hadron Structure (Dept 12); Department of High Energy Nuclear Interactions (Dept 13); The ALICE Experiment Laboratory (NAL); The ATLAS Experiment Laboratory (NAT); High Energy Physics Detector Construction Group (PBD). The research covers a variety of problems of the experimental and theoretical high energy particle physics: the hadronic and leptonic interactions with nucleons and nuclei (characteristics of particle production, including heavy quark physics), e + e - interactions and tests of the Standard Model (also radiative corrections), ultrarelativistic heavy ion interactions and search for the quark-gluon plasma, as well as the spectra, composition and interactions of high energy cosmic ray particles. Research on detectors and accelerator components as well as the development of the apparatus for the high energy physics experiments at future accelerators: LHC (CERN, Geneva), RHIC (Brookhaven), B-Factory (KEK, Tsukuba) and TESLA (DESY) is also presented. The technology of new materials with unique properties such as carbon-carbon composites is also worked on from the point of view of their application in high energy physics experiments. The Division is located in a separate building on the campus of the University of Mining and Metallurgy (UMM). This location, close to the Jagiellonian University (JU), facilitates the collaboration with the latter and with the UMM. The joint weekly seminars carried out for nearly 40 years prove this long term tradition. A substantial part of the activities is teaching and training students from the academic community in Cracow. Joint research, teaching and academic training in the high energy physics are carried out within the M. Miesowicz

CENS - Annual Report 2002

2003-01-01

It is widely recognized that nuclear safety is one of the most important issues in the world. The process of transformation in the former communist countries of Central and Eastern Europe has created a delicate situation for nuclear regulators, often leaving them without necessary human and financial resources. Therefore, regulatory bodies from Central and Eastern European Countries (CEEC) welcomed the idea of the Center for Nuclear Safety in Central and Eastern Europe (CENS) - a non-profit organization that would help them to achieve independence and greater efficiency. After two years of preparation, the Center was founded in March 2002 in Bratislava. Funding for the project was provided by the Swiss Agency for Development and Cooperation (SDC), which saw the Center as a new approach to technical co-operation between regulatory bodies of East and West. The respective planning involved close collaboration between the Swiss Federal Nuclear Safety Inspectorate (HSK), IAEA, Gesellschaft fuer Anlagen- und Reaktorsicherheit mbH (GRS), and Nuclear Regulatory Authority of the Slovak Republic (UJD). The Center's main aims are to improve the independence, competence, and efficiency of nuclear regulatory bodies, and to improve safety in nuclear facilities, by providing a system of networking and international membership for regulators in CEEC and for technical support organizations from around Europe. In this Annual Report activities of the CENS in 2002 year are reported

New Results on the Nearest OB Association: Sco-Cen (Sco OB2)

Mamajek, Eric E.

2013-01-01

The Scorpius-Centaurus OB association (Sco OB2) is the nearest site of recent massive star formation to the Sun. The primary stellar groups in the Sco-Cen complex (including OB subgroups Upper Sco, Upper Cen Lup, and Lower Cen Cru, the neighboring molecular cloud complexes Lup, Cha, CrA, Oph, and dispersed young groups Eta Cha, Epsilon Cha, TW Hya, and Beta Pic) have been participants in a complex episode of stellar birth (and some stellar death) over the past ~20 Myr. Here I summarize some recent results on the Sco-Cen complex from the U. Rochester group: (1) isochronal analysis of the HR diagram positions for >1 Msun stars in the Upper Scorpius subgroup shows it to be twice as old as previously thought (11 Myr vs. 5 Myr), (2) analysis of high resolution optical echelle spectra show that the subgroups are approximately solar in composition, (3) surveys for lower mass members are showing that the complex shows more substructure than previously recognized, including at least one new subgroup ("Lower Sco"), and the velocity and age data for the nearest OB subgroup Lower Cen Cru argue for a bifurcation into a younger 10 Myr) southern part ("Crux") and an older 20 Myr) northern part ("Lower Centaurus"), (4) an eclipsing, multi-ring dust disk system was serendipitously discovered in the SuperWASP and ASAS light curve for the newly discovered K5-type Sco-Cen member 1SWASP J140747.93-394542.6. With regard to some recent results by other investigators, we find that (1) attempts by some authors to subsume the Sco-Cen subgroups into a single sample of a single age are unnecessarily mixing samples with a wide range in ages, and (2) I have been unable to replicate the expansion age determinations claimed by some investigators for the TW Hya and Beta Pic groups (both purported to have expansion ages of 8 and 12 Myr, respectively), which have been used by some investigators to independently age-date the Sco-Cen subgroups.

The research program at the Department of Nuclear Physical Chemistry of the Niewodniczanski Institute of Nuclear Physics is described. The Department consist of three laboratories. First - Laboratory of Physical Chemistry of Separation Processes on which the activity is concentrated on production and separation of neutron deficient isotopes for medical diagnostic. Recently, the main interest was in 111 In which is a promising tracer for cancer diagnostic. To increase the effectiveness of production of indium 111 In the reaction with deuterons on the enriched cadmium target was carried out instead of the previously used one with alpha particles on natural silver. In the second one - Laboratory of Chemistry and Radiochemistry - the systematic studies of physicochemical properties of transition elements in solutions are carried out. The results of the performed experiments were used for the elaboration of new rapid and selective methods for various elements. Some of these results have been applied for separation of trans actinide elements at U-400 cyclotron of JINR Dubna. The third one laboratory -Environmental Radioactivity Laboratory - conducts continuous monitoring of radioactivity contamination of atmosphere. The investigation of different radionuclides concentration in natural environment, mainly in the forest had been carried out

Increasing numbers of physicists engage in research activities that address biological questions from physics perspectives or strive to develop physics insights from active biological processes. The on-going development and success of such activities morph our ways of thinking about what it is to 'do biophysics' and add to our understanding of the physics of life. Many scientists in this research and teaching landscape are homed in physics departments. A challenge for a hosting department is how to group, name and structure such biophysicists to best add value to their emerging research and teaching but also to the portfolio of the whole department. Here we discuss these issues and speculate on strategies. Creative Commons Attribution license.

Absence of positive selection on CenH3 in Luzula suggests that holokinetic chromosomes may suppress centromere drive.

Science.gov (United States)

Zedek, František; Bureš, Petr

2016-12-01

The centromere drive theory explains diversity of eukaryotic centromeres as a consequence of the recurrent conflict between centromeric repeats and centromeric histone H3 (CenH3), in which selfish centromeres exploit meiotic asymmetry and CenH3 evolves adaptively to counterbalance deleterious consequences of driving centromeres. Accordingly, adaptively evolving CenH3 has so far been observed only in eukaryotes with asymmetric meiosis. However, if such evolution is a consequence of centromere drive, it should depend not only on meiotic asymmetry but also on monocentric or holokinetic chromosomal structure. Selective pressures acting on CenH3 have never been investigated in organisms with holokinetic meiosis despite the fact that holokinetic chromosomes have been hypothesized to suppress centromere drive. Therefore, the present study evaluates selective pressures acting on the CenH3 gene in holokinetic organisms for the first time, specifically in the representatives of the plant genus Luzula (Juncaceae), in which the kinetochore formation is not co-localized with any type of centromeric repeat. PCR, cloning and sequencing, and database searches were used to obtain coding CenH3 sequences from Luzula species. Codon substitution models were employed to infer selective regimes acting on CenH3 in Luzula KEY RESULTS: In addition to the two previously published CenH3 sequences from L. nivea, 16 new CenH3 sequences have been isolated from 12 Luzula species. Two CenH3 isoforms in Luzula that originated by a duplication event prior to the divergence of analysed species were found. No signs of positive selection acting on CenH3 in Luzula were detected. Instead, evidence was found that selection on CenH3 of Luzula might have been relaxed. The results indicate that holokinetism itself may suppress centromere drive and, therefore, holokinetic chromosomes might have evolved as a defence against centromere drive. © The Author 2016.

It is impossible to imagine the medical world today without radioisotopes, and due to rapid technological progress in nuclear medicine their use is still on the rise. An important role of research reactors is the production of molybdenum-99. Around the world this is done primarily by five nuclear research reactors, one of which is the BR2 reactor of SCK-CEN. As a result of checks and maintenance work on three other reactors, for a few years there has been a serious crisis in the availability of this medical isotope. In order to guarantee the worldwide supply of radioisotopes, SCK-CEN expanded its production of molybdenum-99 by 50 percent in 2010.

1987-01-01

The authors characterized the in vivo transcripts of two Cellulomonas fimi genes, which encodes an extracellular endo-β-1,4-glucanase. By Northern blot analysis, cenA mRNA was detected in C. fimi RNA preparations from glycerol- and carboxymethyl cellulose-grown cells but not from glucose-grown cells. In contrast, cex mRNA was detected only in the preparations from carboxymethyl cellulose-grown cells. Therefore, the transcription of these genes is subject to regulation by the carbon source provided to C. fimi. By nuclease SI protection studies with unique 5'-labeled DNA probes and C. fimi RNA isolated in vivo, 5' termini were found 51 and 62 bases before the cenA translational initiation codon and 28 bases before the cex translational initiation codon. S1 mapping with unlabeled DNA probes and C. fimi RNA which had been isolated in vivo but which had been 5' labeled in vitro with guanylyltransferase and [α- 32 P]GTP confirmed that true transcription initiation sites for cenA and cex mRNA had been identified. Comparative analysis of the DNA sequences immediately upstream of the initiation sites of the cenA and cex mRNAs revealed a 30-base-pair region where these two sequences display at least 66% homology. S1 mapping was also used to locate the 3' termini of the cenA and cex transcripts. Three 3' termini were found for cenA messages, whereas only one 3' terminus was identified for cex mRNA. The transcripts of both genes terminate in regions where their corresponding DNA sequences contain inverted repeats

A Bayesian approach to the modelling of α Cen A

Determining the physical characteristics of a star is an inverse problem consisting of estimating the parameters of models for the stellar structure and evolution, and knowing certain observable quantities. We use a Bayesian approach to solve this problem for α Cen A, which allows us to incorporate prior information on the parameters to be estimated, in order to better constrain the problem. Our strategy is based on the use of a Markov chain Monte Carlo (MCMC) algorithm to estimate the posterior probability densities of the stellar parameters: mass, age, initial chemical composition, etc. We use the stellar evolutionary code ASTEC to model the star. To constrain this model both seismic and non-seismic observations were considered. Several different strategies were tested to fit these values, using either two free parameters or five free parameters in ASTEC. We are thus able to show evidence that MCMC methods become efficient with respect to more classical grid-based strategies when the number of parameters increases. The results of our MCMC algorithm allow us to derive estimates for the stellar parameters and robust uncertainties thanks to the statistical analysis of the posterior probability densities. We are also able to compute odds for the presence of a convective core in α Cen A. When using core-sensitive seismic observational constraints, these can rise above ˜40 per cent. The comparison of results to previous studies also indicates that these seismic constraints are of critical importance for our knowledge of the structure of this star.

Full text: The 31 st International Cosmic Ray Conference (31.ICRC) was held in Lodz on 7-15 July 2009. The Conference was organized by the University of Lodz (Department of High Energy Astrophysics and Department of Astrophysics) and IPJ (Department of Cosmic Ray Physics). ICRCs are held every two years and are the largest forums to present and discuss the current status of Cosmic Ray studies. The Conference we co-organized gathered about 750 scientists (including about 50 from Poland). This was a remarkable event. The Department of Cosmic Ray Physics in Lodz is involved in basic research in the field of high energy Cosmic Rays. Cosmic Rays are energetic panicles from outside the Solar System. Most studies of Cosmic Rays address fundamental problems: - the nature of the physical and astrophysical processes responsible for the high energies of the particles. - experimental search for sources of Cosmic Rays, - studies of the astrophysical conditions at the acceleration sites, - properties of particle interactions at very high energies. Presentation of Cosmic Ray registration to high school students has become a popular way to introduce panicle physics detectors and elementary particle detection techniques to young people, in Lodz and Poznan we organize workshops on particle physics for high school students. This is part of the European activity: EPPOG Masterclass - Hands on CERN. Energetic Cosmic Ray particles produce cascades of panicles in the atmosphere, called Extensive Air Showers (EAS). Registering EASs and their properties is the main means of studying experimentally high energy Cosmic Rays: · The satellite experiment JEM-EUSO will observe EASs from the International Space Station. The main target is to find Cosmic Ray Sources for the highest energy Cosmic Rays. JEM-EUSO will collect a large number of events since it will observe a large area of the atmosphere. We are participating in the preparation of this mission. · The KASCADE-Grande addresses

Management of radioactive scrap metal at SCK-CEN

Noynaert, L.; Klein, M.; Cornelissen, R.; Ponnet, M.

2000-01-01

The environmental concern and public perception as well as the steadily increase of the conditioning and disposal costs are pushing the nuclear sector to minimise the amount of radioactive waste. Hence it is a strong incentive to prefer the management option 'recycling and reuse' instead of the option 'disposal and replacement'. The 'recycling and reuse' option requires the availability of decontamination techniques as well as measuring techniques allowing to prove that the release criteria are met. Therefore SCK-CEN has now two decontamination installations for scrap metal on its own site. One installation uses a wet abrasive technique while the other one uses a chemical process based on the Ce 4+ . These two installations, combined with the use of foundries for free release or for radioactive scrap metal recycling are now common practices at SCK-CEN and will allow to reduce the metallic waste to 10% of the metallic scrap production and the costs at least by a factor 2.5.

An astrometric standard field in omega Cen

Science.gov (United States)

Wyse, Rosemary

2003-07-01

We propose to obtain a high-precision astrometric standard in a two-step procedure. First, we will create a ground-based astrometric standard field around omega Cen down to V=22 with a 3 mas accuracy in positions and better than 0.5 mas/yr in proper motions. This standard will be used to obtain precise absolute plate solutions for selected WFPC2 CCD frames and refine the self-calibrated mean distortion solution for the WFPC2 CCD chips. This will eliminate systematic errors inherent in the self-calibration techniques down to the rms=0.3 mas level, thus opening new opportunities to perform precision astrometry with WFPC2 alone or in combination with the other HST imaging instruments. We will also address the issue of the distortion's variation which has a paramount significance for space astrometry such as spearheaded by the HST or being under development {SIM, GAIA}. Second, all reduced WFPC2 CCD frames will be combined into the two field catalogs {astrometric flat fields} of positions in omega Cen of unprecedented precision {s.e.=0.1 mas} down to V=22 and will be available to the GO community and readily applicable to calibrating the ACS.

Assessing the physical service setting: a look at emergency departments.

Science.gov (United States)

Steinke, Claudia

To determine the attributes of the physical setting that are important for developing a positive service climate within emergency departments and to validate a measure for assessing physical service design. The design of the physical setting is an important and contributing factor for creating a service climate in organizations. Service climate is defined as employee perceptions of the practices, procedures, and behaviors that get rewarded, supported, and expected with regard to customer service and customer service quality. There has been research conducted which identifies antecedents within organization that promotes a positive service climate which in turn creates service-oriented behaviors by employees toward clients. The antecedent of the physical setting and its impact on perceptions of service climate has been less commonly explored. Using the concept of the physical service setting (which may be defined as aspects of the physical, built environment that facilitate the delivery of quality service), attributes of the physical setting and their relationship with service climate were explored by means of a quantitative paper survey distributed to emergency nurses (n = 180) throughout a province in Canada. The results highlight the validity and reliability of six scales measuring the physical setting and its relation to service. Respondents gave low ratings to the physical setting of their departments, in addition to low ratings of service climate. Respondents feel that the design of the physical setting in the emergency departments where they work is not conducive to providing quality service to clients. Certain attributes of the physical setting were found to be significant in influencing perceptions of service climate, hence service quality, within the emergency department setting. © The Author(s) 2015.

In spite of drastic reduction of scientific and technical staff (from 16 to 10 persons) the planned works were successfully completed, but requested some extraordinary efforts. In realisation of 6/15 MeV Accelerator Project, the Department was responsible all along the project for calculations of all most important parts (electron gun, accelerating structure, beam focusing, achromatic deviation) and also for construction and physical modelling of some strategic subassemblies. The results of scientific and technical achievements of our Department in this work are documented in the Annex to Final Report on realisation of KBN Scientific Project No PBZ 009-13 and earlier Annual Reports 2000 and 2001. The results of Monte Carlo calculations of narrow photon beams and experimental verification using Varian Clinac 2003CD, Simens Mevatron and CGR MeV Saturn accelerators ended up with PhD thesis prepared by MSc Anna Wysocka. Her thesis: Collimation and Dosimetry of X-ray Beams for Stereotactic Radiotherapy with Linear Accelerators was sponsored by KBN scientific Project Nr T11E 04121. In collaboration with LNF INFN Frascati the electron beam deflectors were designed for CERN CLIC Test Facility CTF3. These special type travelling wave RF structures were built by our Department and are actually operated in CTF3 experiment.

Public Relations for Physics Departments: Convincing the Community that Quarks are Cool

A strong public relations program can be of great importance to a physics department. Not only can effective PR improve the reputation of an individual department, but it can also serve the greater physics community by convincing the public that quarks, quantum dots, and nanostructures are cool. Building a solid reputation with the many constituents that a physics department serves can lead to greater media exposure, improved quality of student applicants, community and industrial partnerships, and even financial support. It isn’t difficult to create a strategic PR program, but it does take planning and commitment of resources. I will discuss the techniques and tactics of effective media, community, alumni, and internal relations, with special emphasis placed on establishing connections with media outlets, creating and publicizing outreach programs for the community, initiating a newsletter, organizing an external board of advisors, and developing an effective alumni relations program. The University of Arizona Physics Department serves as a case study, but other physics departments with similar communications programs will also be incorporated.

Full text: The Department of Cosmic Ray Physics in Lodz is involved in basic research in the area of high-energy physics and cosmic ray physics related to: Experimental and phenomenological studies of Extensive Air Showers induced by cosmic ray particles. Studies of ultra-high energy (above 10 19 eV) cosmic rays: determination of energy and primary particle mass composition. Studies of asymptotic properties of hadronic interactions based on the analysis of cosmic ray propagation through the atmosphere. Studies of mass composition of cosmic rays in the energy range 10 15 -10 17 eV. Registration of cosmic ray intensity variation correlated with solar activity. Theoretical and experimental studies of Extensive Air Shower properties are performed mostly based on the results obtained by the Lodz Extensive Air Shower Array. We have noticed unexplainable delayed signals registered about 500-900 microseconds after the main EAS pulse. We prepared hardware for further experimental study of this effect. In September we have started registration of 5 GeV muon flux with the underground muon telescope. We registered 3 decreases of muon intensity correlated with Forbush decreases registered at lower energies. Variations of primary cosmic ray of energies up to about 100 GeV were responsible for our registrations. These set the upper limits for geometrical size of geomagnetic disturbances in interplanetary space. In construction and data interpretation of cosmic ray experiments, the Lodz group collaborates with many foreign institutes and laboratories: Forschungszentrum in Karlsruhe (Germany), College de France, Institute for Nuclear Studies of the Russian Academy of Sciences and Uppsala University (Sweden). We have organised (together with the Physics Department of the University of Lodz) the 17 th European Cosmic Ray Symposium (24-?8 July 2000) in which about 150 physicists participated (about 100 from abroad).

Full text: The Department of Cosmic Ray Physics in Lodz is involved in basic research in the high energy Cosmic Ray field. Cosmic Rays are energetic particles from outside the Solar System. The energy spectrum (power law energy dependence) suggests a non-thermal origin of these particles. Most studies of Cosmic Rays address fundamental problems: - the nature of the physical and astrophysical processes responsible for high energies of particles (up to about 10 20 eV/particle), - estimation of the astrophysical conditions at the acceleration sites and/or search for sources of Cosmic Rays, - properties of high energy particle interactions at very high energies (nuclear interactions at energies exceeding energy available in laboratories). - Some Cosmic Ray studies might have practical (commercial) implications, e.g. - ''cosmic weather'' forecast - predictions of geomagnetic disturbances related to Solar activity changes (due to large Solar Flares / events of Coronal Mass Ejection); these are important for large electricity networks, gas pipes, radio-wave connections, space missions and satellite experiments. Presentation of Cosmic Ray registration to high school students is a popular way to introduce particle physics detectors and elementary particle detection techniques to young people. Energetic Cosmic Ray particles produce cascades of particles in the atmosphere, called Extensive Air Showers (EAS). Registering the EAS and their properties is the main way of experimental studies of very high energy Cosmic Rays. In our Lodz Department we run an Extensive Air Shower array where EAS are continuously being registered. We concentrate on the studies of detection of neutrons correlated with EAS and interpretation of this phenomenon.

Considerable experience has been gained over the past years in the use of control and treatment technologies, applied to contaminated sites and environments. Although available technologies are adequate in many cases, it is recognized that many technologies are too costly or inadequate to address the multitude of contaminant problems. This insight has led national and international organizations as well as private organizations and universities to sponsor environment technology programmes to address technology needs. The United States Department of Energy for example has initiated an aggressive environmental technology development programme and the Commission of the European Union is sponsoring environmental technology development. An overview is given of innovative and emerging technologies that may become important. Opportunities for SCK/CEN in research, development, and demonstration programmes are outlined.

We present a multi-band photometric catalog of ≈1.7 million cluster members for a field of view of ≈2° × 2° across ω Cen. Photometry is based on images collected with the Dark Energy Camera on the 4 m Blanco telescope and the Advanced Camera for Surveys on the Hubble Space Telescope . The unprecedented photometric accuracy and field coverage allowed us, for the first time, to investigate the spatial distribution of ω Cen multiple populations from the core to the tidal radius, confirming its very complex structure. We found that the frequency of blue main-sequence stars is increasing compared to red main-sequence stars starting from a distance of ≈25′ from the cluster center. Blue main-sequence stars also show a clumpy spatial distribution, with an excess in the northeast quadrant of the cluster pointing toward the direction of the Galactic center. Stars belonging to the reddest and faintest red-giant branch also show a more extended spatial distribution in the outskirts of ω Cen, a region never explored before. Both these stellar sub-populations, according to spectroscopic measurements, are more metal-rich compared to the cluster main stellar population. These findings, once confirmed, make ω Cen the only stellar system currently known where metal-rich stars have a more extended spatial distribution compared to metal-poor stars. Kinematic and chemical abundance measurements are now needed for stars in the external regions of ω Cen to better characterize the properties of these sub-populations.

The antimicrobial effect of CEN1HC-Br against Propionibacterium acnes and its therapeutic and anti-inflammatory effects on acne vulgaris.

Han, Rui; Blencke, Hans-Matti; Cheng, Hao; Li, Chun

Propionibacterium acnes is a commensal bacterium, which is involved in acne inflammation. An antimicrobial peptide named CEN1HC-Br, which was isolated and characterized form the green sea urchin, has been shown to possess broad-spectrum antibacterial activity. Little is known concerning the potential effects of its antibacterial and anti-inflammatory properties against P. acnes. To examine the potency of CEN1HC-Br in acne treatment, we conducted experiments to analyze the antibacterial and anti-inflammatory activities of CEN1HC-Br both in vitro and in vivo. The antimicrobial activity of CEN1HC-Br was evaluated by minimal inhibitory concentration (MIC) assays using the broth dilution method. To elucidate the in vitro anti-inflammatory effect, HaCaT cells and human monocytes were treated with different concentration of CEN1HC-Br after stimulation by P. acnes. The expression of TLR2 and the secretion of the pro-inflammatory cytokines IL-6, IL-8, IL-1β, TNF-α, IL-12, respectively, were measured by enzyme immunoassays. An evaluation of P. acnes-induced ear edema in rat ear was conducted to compare the in vivo antibacterial and anti-inflammatory effect of CEN1HC-Br, the expression of IL-8, TNF-α, MMP-2 and TLR2 was evaluated by immunohistochemistry and real time-PCR. CEN1HC-Br showed stronger antimicrobial activity against P. acnes than clindamycin. CEN1HC-Br significantly reduced the expression of interleukin IL-12p40, IL-6, IL-1β, TNF-α and TLR2 in monocytes, but they were not influenced by clindamycin. Both CEN1HC-Br and Clindamycin attenuated P. acnes-induced ear swelling in rat along with pro-inflammatory cytokines IL-8, TNF-α, MMP-2 and TLR2. Our data demonstrates that CEN1HC-Br is bactericidal against P. acnes and that it has an anti-inflammatory effect on monocytes. The anti-inflammatory effect may partially occur through TLR2 down-regulation, triggering an innate immune response and the inhibition of pro-inflammatory cytokines. Copyright © 2017 The

Improving Climate and Gender Equity in Physics Departments

We need to open the door of science to women and minorities. We need to invite them in and encourage them to succeed. We need to teach them the secret handshake and transfer all the writing on the men's room walls and all-white country clubs into accessible places. We need to promote them to positions of national prominence. We need to do this out of respect to our mothers and the pioneering scientists who have come before us. We need to do this for our daughters and sons, so that our grandchildren may only know this discrimination as a piece of history. We need to do this now -- for the sake of our country, our science, our technical workforce, our economy and because it is the right thing to do. The Committee on the Status of Women in Physics (CSWP) has been helping physics departments improve their climate as a means to enhance gender equity. The CSWP site visit program has been giving departments valuable feedback on their climate for many years. In May 2007, a workshop on ``Gender Equity: Enhancing the Physics Enterprise in Universities and National Laboratories'' was held to address the issue of underrepresentation of women in physics by engaging the stake holders. This fall a new ``Conversation on Gender Equity'' has begun. Successful strategies for improving the climate and increasing the representation of women in physics will be presented. )

Towards Optimality in Online Learning – The OLeCenT Approach

Full Text Available Higher Education Institutions (HEIs employ Learning Management Systems (LMSs primarily for greater efficiency, profitability, technological advancement or survival. The predominantly used LMSs, Moodle and Blackboard account for in excess of 60% usage by the top HEIs. However, the individual international regions do not necessarily bear the percentages of the overall total. Gaps are identified in optimality in course delivery within online learning when one studies LMSs and their functionalities. Advanced Distributed Learning (ADL Initiative which was established to standardize and modernize training and education management and delivery, developed and recommended usage of Sharable Content Object Reference Model (SCORM 2004 and later versions. SCORM 2004 which provides for flexibility in sequencing and navigation for learner-centric course delivery is not supported in any version of the more prevalently used LMSs. It is believed that most people have a preferred way in processing information. We propose codifying one or more Learning Style Instruments (LSIs, diagnosing the preferred teaching approach(es and dominant/existing learning styles within a batch of learners, then providing course delivery as a best-fit per learner. As a proof of concept, OLeCenT allows the input of one or more course learning paths with real-time learning and automatic reconfiguration of the course path where a new trend or pattern is identified. OLeCenT identified disparity in teaching-learning and provided a mechanism towards improving online learner-centric course delivery. OLeCenT also identified comparative levels of similarities among learners and instructors even where they are deemed to be of different teaching-learning styles/mechanisms.

An ongoing analysis of data from large accelerator facilities At CERN SPS: The Compass experiment, ' a flagship of the CERN fixed target program ', studies the structure of the nucleon. Gluon polarization analysis was the main subject this year. Compass is an active experiment, and there is an ongoing effort in data taking and detector development. Two heavy ion experiments, WA98 and NA49, have finished data taking, but continue analysis. In 2008, important results on transverse momentum spectra were published. At COSY: The WASA experiment works with low energy (up to 3.7 GeV) beams of protons and deuterons, studying rare decays of eta mesons. New limits on branching ratios for such decays have been determined. This information is important for the theory of C and CP symmetry, and chiral perturbation theory. II. Preparations for soon-to-be-operating experiments at the LHC Three teams work on LHC experiments: CMS, LHCb and ALICE. The CMS experiment is ready for data taking. The muon trigger system, based on resistive plate chambers RPC, has been installed and tested using cosmic ray muons. Simulations of physical processes predicted by some extensions of the Standard Model were performed. The LHCb experiment team has worked on the system of the Inner Detector positioning station Rasnik, and the beam phase and intensity monitor (together with a P-III team). Simulations of the B decays into vector mesons, for the High Level Trigger, were performed. The ALICE team has worked on the installation of the photon detector PHOS and tests with cosmic muons. Simulations of neutral pion reconstruction were performed. Preparation of the computing base for future large experiments - work within the Worldwide LHC Computing Grid was actively pursued by a dedicated team. In 2008, many activities were directed at information and popularization of LHC physics. Our department members actively

Full Text Available Há crescentes pressões para que sejam adotados hábitos sustentáveis pela sociedade, o que impacta diversos mercados, incluindo os de energia. Combustíveis fósseis são fontes finitas, não renováveis e responsáveis por emissões consideráveis de CO2 na atmosfera. Nesse contexto, o etanol é apontado com umas das alternativas mais viáveis de fornecimento de energia limpa e renovável. O Brasil possui liderança tecnológica no setor devido ao lançamento do Proálcool na década de 1970. Nos anos 2000, o País despontou novamente na produção do biocombustível, passando a enfrentar concorrência maior de players norte-americanos e da União Europeia. Para o futuro, podem ser apontadas diversas incertezas que o setor enfrentará, sendo a prospecção baseada em cenários uma forma de modelar tais incertezas e auxiliar o desenvolvimento de estratégias robustas para as empresas que pretendem investir no setor. O objetivo neste trabalho foi desenvolver quatro cenários para o comércio internacional de etanol em 2020 e discutir as implicações para as estratégias empresariais. Para tanto, foi utilizado o método de elaboração de cenários em uma abordagem exploratória e qualitativa. Os cenários apresentados no estudo podem ser utilizados por empresas e diferentes stakeholders para testar opções estratégicas e de investimentos no setor de etanol.

In the opinion of the authors a department caring for inpatients with acute rheumatic diseases must, as a minimum, have the facilities and equipment necessary for offering thermotherapeutic treatment. Staff trained in physical therapeutic procedures and occupational therapy is also crucial. Moreover, it is desirable that the staff should be trained in manual therapy.

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

Science.gov (United States)

Seeley, Lane

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.

Reactor Physics Training

International Nuclear Information System (INIS)

Baeten, P.

2007-01-01

University courses in nuclear reactor physics at the universities consist of a theoretical description of the physics and technology of nuclear reactors. In order to demonstrate the basic concepts in reactor physics, training exercises in nuclear reactor installations are also desirable. Since the number of reactor facilities is however strongly decreasing in Europe, it becomes difficult to offer to students a means for demonstrating the basic concepts in reactor physics by performing training exercises in nuclear installations. Universities do not generally possess the capabilities for performing training exercises. Therefore, SCK-CEN offers universities the possibility to perform (on a commercial basis) training exercises at its infrastructure consisting of two research reactors (BR1 and VENUS). Besides the organisation of training exercises in the framework of university courses, SCK-CEN also organizes theoretical courses in reactor physics for the education and training of nuclear reactor operators. It is indeed a very important subject to guarantee the safe operation of present and future nuclear reactors. In this framework, an understanding of the fundamental principles of nuclear reactor physics is also necessary for reactor operators. Therefore, the organisation of a basic Nuclear reactor physics course at the level of reactor operators in the initial and continuous training of reactor operators has proven to be indispensable. In most countries, such training also results from the direct request from the safety authorities to assure the high level of competence of the staff in nuclear reactors. The objectives this activity are: (1) to provide training and education activities in reactor physics for university students and (2) to organise courses in nuclear reactor physics for reactor operators

Noynaert, L.; Massaut, V.; Braeckeveldt, M.

1999-01-01

The back-end management of fissile materials at SCK-CEN mainly concerns the HEU spent fuel of the BR2 (MTR) and the LEU and MOX spent fuel of the BR3, the first PWR installed in Western Europe and in decommissioning since 1987. It also concerns the experimental fuels tested in the SCK-CEN facilities. Furthermore as a result of its R and D programs in reprocessing and characterisation of spent fuel, considerable amounts of fissile materials in all kinds of forms and characteristics are stored in the different laboratories. For these, six main types of fissile materials are identified: highly enriched uranium, experimental spent fuel from the fast breeder programmes, MOX fuel, low enriched fuel, natural uranium and lab fissile materials. For the BR2 and BR3 spent fuel, various options, i.e. reprocessing, dry storage in casks and dry storage in canisters were evaluated against criteria, e.g. available techniques, safety, waste production, overall costs and policies. As a result of these studies, it was decided to opt in the case of the HEU from the BR2 reactor for the reprocessing without recovery of uranium while for the LEU and MOX fuel from the BR3 reactor, the dry storage in containers was chosen. For the others, the studies are still in progress. (author)

Full Text Available Estudos de cenários são desenvolvidos por governos e organizações como meio para vislumbrar futuros possíveis e assim realizar o traçado de suas estratégias. Ocorre que existem poucas pesquisas que avaliem a efetividade desses estudos. Normalmente o que se encontra na literatura são atributos destinados a avaliar o documento de apresentação do cenário. Nesse sentido, uma abordagem possível é a distinção entre o conteúdo, ou seja, o produto cenário propriamente dito, e o processo que dá suporte à sua elaboração. Nesse contexto teórico, a pesquisa objetivou propor e aplicar um método para avaliar a maturidade do processo de cenários nas organizações. Em consequência, identificaram-se os componentes e subcomponentes principais do processo de cenários que permitam avaliá-los; definiram-se as métricas que indiquem os estágios de maturidade organizacional em cenários; e realizou-se um exercício de aplicação do método por meio de pesquisa a um conjunto de organizações brasileiras selecionadas. Como uma alternativa possível para basear o método proposto, foi utilizado o modelo de maturidade em gerenciamento de projetos (MMGP. Assim, empreendeu-se um estudo multimetodológico, qualitativo e interpretativo para a coleta e interpretação dos dados, constando de levantamento bibliográfico, entrevistas com expertises do meio acadêmico e uso de técnica de análise de conteúdo. Como resultado, obteve-se uma proposta de avaliação do processo de cenários nas organizações, na qual se consideraram as seguintes etapas: preparação, elaboração, produção do documento e utilização. Para determinar qual o estágio alcançado em cenários, os estágios foram assim classificados: inativo, iniciado, padronizado, gerenciado e otimizado, culminando nos níveis de maturidade muito fraco, fraco, regular, bom, ótimo e excelente. O exercício de aplicação do método com 13 organizações brasileiras identificou

The main problem of clinical prevention and control of multi drug resistant bacteria infection is to strengthen the monitoring of pathogenic bacteria spectrum, this study research on the multi drug-resistant bacteria infection and nursing quality management application in the department of physical examination. The results of this study showed that the number of patients with multiple drug resistant infections showed an increasing trend. Therefore, once the patients with multiple drug-resistant bacteria infection are found, the prevention and control of the patients with multiple drug-resistant bacteria should be strictly followed, and the patient's medication care should be highly valued. Also, the nurses need to be classified based on the knowledge and skill characteristics of the nurses in the department of physical examination, and compare the nursing effect before and after classification and grouping. The physicians and individuals receiving physical examinations in the department of physical examination had a higher degree of satisfaction for nursing effect after classification compared with those before classification. Classification and grouping management helps improve the nursing quality and overall quality of the nurses in the department of physical examination.

Full text: In April 2009 the Department of Materials Studies was united with the Department of Plasma Physics and Technology, This action followed twenty years of close cooperation in the implementation of high-intensity ion-beam pulses for the implantation of materials. In 2009 the activities of the new Department continued previous studies in the following fields of plasma physics, controlled nuclear fusion and plasma engineering: · Development of selected methods for high-temperature plasma diagnostics; · Studies of physical phenomena in pulsed discharges at the Plasma-Focus and RPI-IBIS facilities; · Research on plasma technologies, search for new methods of surface engineering; · Selected problems of plasma theory and computational modelling. In the framework of the EURATOM program. efforts were devoted to the development of diagnostics methods for tokamak-type facilities. Such studies included the elaboration of a special detection system based on a Cherenkov-type detector. Other fusion-oriented efforts were connected with the application of activation methods to the investigation of neutrons from the JET tokamak. Also. solid-state nuclear track detectors of the PM-355 type were used for measurements of energetic protons emitted from ultra-intense laser produced plasmas. In our continuing experimental studies, particular attention was paid to the development and application of optical spectroscopy for diagnostics of high-temperature plasma within the RPI-IBIS device and Plasma-Focus facilities. Fast ions escaping from the plasma were studied with nuclear track detectors, The interaction of plasma-ion streams with different targets was also investigated. A field of research activity was related to plasma technology. Efforts were undertaken to improve the ultra-high vacuum (UHV) deposition of thin superconducting layers. c.g. pure niobium film on the surface of copper resonant cavities of accelerators. The vacuum arc deposition technique was also applied to

Starting with 2000, the expert group Society and Policy Support carries out research on various aspects of risk governance. Measuring several risk perception items at regular intervals with the Belgian population is an important part of this research. SCK-CEN has organised a first risk perception barometer in 2002 and a second one in 2006. The 2006 barometer is based on 1063 Computer Assisted Personal Interviews, with a duration of approximately 35 minutes. The large scale of the survey ensures that general trends can be detected and allows specific and detailed analysis on subgroups of the population. Besides the classical background variables used to obtain a sample representative for the Belgian 18+ population (age, language, habitat, gender and social class), several questions were included assessing the sociological context and the psychological personality profile. A series of questions on risk perception, confidence in authorities and specific nuclear topics were repeated in 2006 and constitute a fixed core, allowing comparison over time in Belgium, as well as with the results from the IRSN French barometer. In addition, a number of topics such as acceptance of legal norms and management options for radioactively contaminated milk, energy, nuclear waste and the perception of the Chernobyl accident were covered in detail in the 2006 edition of the SCK-CEN barometer

Miniature fission chambers are suited tools for instrumenting experimental reactors, allowing online and in-core neutron measurements of quantities such as fission rates or reactor power. A new set of such detectors was produced by CEA to be used during the next experimental program at the EOLE facility starting in 2013. Some of these detectors will be employed in pulse mode for absolute measurements, thus requiring calibration. The calibration factor is expressed in mass units and thus called 'effective mass'. A calibration campaign was conducted in December 2012 at the SCK.CEN BR1 facility within the framework of the scientific cooperation VEP (VENUS-EOLE-PROTEUS) between SCK.CEN, CEA and PSI. Two actions were conducted in order to improve the calibration method. First a new characterisation of the thermal flux cavity and the MARK3 neutron flux conversion device performed by SCK.CEN allowed using calculated effective cross sections for determining detectors effective masses. Dosimetry irradiations were performed in situ in order to determine the neutron flux level and provide link to the metrological standard. Secondly two fission chambers were also calibrated at the CEA CALIBAN reactor (fast neutron spectrum), using the same method so that the results can be compared with the results obtained at the SCK.CEN. In this paper the calibration method and recent improvements on uncertainty reduction are presented. The results and uncertainties obtained in the two reactors CALIBAN and BR1 are compared and discussed. (authors)

Research in the Physics Department covers two main fields: condensed matter physics and plasma physics. The principal activites in these fields are presented in this Progress Report covering the period from 1 January to 31 December 1989. The condensed matter physics research is predominantly experimental utilising diffraction of neutrons and x-rays. The research topics range from studies of two- and three-dimensional structures, magnetic ordering, heavy fermions, phase transitions in model systems to studies of texture and recrystallization kinetics with a more applied nature. The discovery of the high Tc superconductors in 1986 has opened an important new research area, where neutron and x-ray diffraction are used to elucidate the basic mechanism responsible for the superconductivity and in the analysis of the solid state syntheses used in producing the materials. The plasma physics research is partly experimental and partly theoretical. The plasma physics programme is also of a wide scope ranging from fundamental studies of wave propagation, instabilities, solitons and turbulence in plasmas to refuelling a fusion reactor by deuterium-tritium pellets.

problems with DKFZ Heidelberg, where she participates in the development so called scanning collimators. As a result of a collaboration with LNF INFN Frascati, apart from two travelling wave RF structures now operated in the CTF3 experiment at CERN, one additional TW structure was made in our Department. It serves as an experimental unit for further study of TW technology. The collaboration with the DESY TESLA-FEL Project during the past years concerned mainly the RF accelerating super-conducting superstructures. This work ended with good results; it was reported in a common international oral session held during PAC2003 in Portland, USA. The superstructures have a chance to be mass-produced if the TESLA Superconducting Collider gets international financial approval. The work on RF vacuum windows upgrading against the multipactor effects in high power couplers was continued at DESY till the end of 2003. The original new technologies of thin TiN coating of ceramic windows were applied using newly constructed coating set-up. The summary of our 2003 results on coating will be presented in the TESLA Report 2004-02. A prerequisite of practising Accelerator Physics is understanding its importance in the wider context. Looking to professional literature on accelerators applications, one finds that in the developed world roughly 20000 accelerators exist (excluding electron units below 0.2 MeV) and yearly this number increases by at least 10%. More than half are used for material modification and roughly 30 % in radiotherapy. The most advanced technically and technologically are accelerators for subatomic physics and synchrotron radiation sources, where the total number of existing or under construction machines surpasses 200. New solutions, new technologies, cost reductions are still being investigated. So, in spite of difficult financial conditions, there is real motivation to keep accelerator physics alive in our Institute. (author)

BH Cen is a short-period early-type binary with a period of 0.792d in the extremely young star-forming cluster IC 2944. New multi-color CCD photometric light curves in U, B, V, R and I bands are presented and are analyzed by using the Wilson-Devinney code. It is detected that BH Cen is a high-mass-ratio overcontact binary with a fill-out factor of 46.4% and a mass ratio of 0.89. The derived orbital inclination i is 88.9 degrees, indicating that it is a totally eclipsing binary and the photometric parameters can be determined reliably. By adding new eclipse times, the orbital period changes in the binary are analyzed. It is confirmed that the period of BH Cen shows a long-term increase while it undergoes a cyclic oscillation with an amplitude of A 3 = 0.024 d and a period of P 3 = 50.3 yr. The high mass ratio, overcontact configuration and long-term continuous increase in the orbital period all suggest that BH Cen is in the evolutionary state after the shortest-period stage of Case A mass transfer. The continuous increase in period can be explained by mass transfer from the secondary component to the primary one at a rate of Ṁ 2 = 2.8 × 10‑6 M ⊙ per year. The cyclic change can be plausibly explained by the presence of a third body because both components in the BH Cen system are early-type stars. Its mass is determined to be no less than 2.2 M ⊙ at an orbital separation of about 32.5 AU. Since no third light was found during the photometric solution, it is possible that the third body may be a candidate for a compact object.

Adotando a postura prospectiva que informou todo esse projeto, o artigo indica algumas das linhas de força que deverão estabelecer o elo entre o sistema internacional presente e o que haverá no futuro, em um horizonte de vinte anos, destacando entre outros o papel dos EUA, da Europa e da China nesse processo. Quatro cenários são utilizados como base para a análise do caso brasileiro: Desconcentração conflituosa, Multipolaridade benigna, Unipolar consolidado e Ordem liberal cosmopolita. Considera-se aqui o Brasil como um país intermediário, afastado das áreas críticas de tensão internacional, e que, portanto, dispõe de certa margem de manobra e razoável condição para definir suas estratégias internacionais.THIS article presents part of the results of a broad research about Brazil and international scenarios. Assuming the same prospective view of the research project, this article indicates a few current driving forces that will contribute to define international order in the future, in a 20 years perspective. The roles of the USA, Europe and China are highlighted in this analysis. Four scenarios are used as parameters for the analysis of the Brazilian case: conflictive deconcentration, benign multipolarity; consolidated unipolarity and cosmopolitan liberal order. We consider Brazil as an Intermediate State out of the critical areas of international conflict. We also consider that Brazil has certain margin for maneuver and reasonable amount of capacity to define its international strategies.

Mulvey, Patrick; Ivie, Rachel; Campbell, David; Murnane, Margaret; Kirby, Kate; Catlla, Anne

2006-03-01

The decade of the 90's was a period of intense scrutiny of climate issues in physics departments, e.g. the status of women, the job situation for new Ph.D.'s and postdocs, and the preparation of physicists for careers inside and outside of physics. There were many conference sessions on these topics, and both APS members and leadership instigated important efforts to focus on specific areas. These efforts included the program of visiting committees to departments to examine the situation for women by the Committee on the Status of Women in Physics, the AIP's various studies of a statistical nature, and the creation by the APS of a Committee on Careers and the Forum on Graduate Student Affairs, as well as the recent APS-AAPT task force on graduate education. This forum patterned after similar sessions 10 years ago - will examine how physics departments have changed as a result of such efforts. It will begin with short (12-minute) talks by a panel of experts to describe what has happened in key areas. The greater part of the session will be a period of observations, questions, and discussion from the audience and the panel together. The purpose is to have an interchange on these interrelated topics from which we can all learn. THE TOPICS TO BE INTRODUCED IN THE SHORT TALKS AT THE BEGINNING OF THE SESSION ARE: 1) changes in graduate enrollment, composition, and subsequent jobs (Patrick Mulvey); 2) women in physics and astronomy departments 2005 (Rachel Ivie); 3) changes in graduate curricula and environment (David Campbell); 4) CSWP site visits to physics departments what’s been accomplished and learned (Margaret Murnane); 5) survey of ethical issues in physics departments and the physics profession: results and reactions (Kate Kirby); and (6) physics departments from the point of view of younger physicists (Anne Catlla). The bulk of the session will be a public forum, on these and related issues, among the audience and the panel.

A highly important factor in enhancing quality of patient care and job satisfaction of health care staff is inter-professional communication. Due to the critical nature of the work environment, the large number of staff and units, and complexity of professional tasks and interventions, inter-professional communication in an emergency department is particularly and exceptionally important. Despite its importance, inter-professional communication in emergency department seems unfavorable. Thus, this study was designed to explain barriers to inter-professional communication in an emergency department. This was a qualitative study with content analysis approach, based on interviews conducted with 26 participants selected purposively, with diversity of occupation, position, age, gender, history, and place of work. Interviews were in-depth and semi-structured, and data were analyzed using the inductive content analysis approach. In total, 251 initial codes were extracted from 30 interviews (some of the participants re-interviewed) and in the reducing trend of final results, 5 categories were extracted including overcrowded emergency, stressful emergency environment, not discerning emergency conditions, ineffective management, and inefficient communication channels. Tumultuous atmosphere (physical, mental) was the common theme between categories, and was decided to be the main barrier to effective inter-professional communication. Tumultuous atmosphere (physical-mental) was found to be the most important barrier to inter-professional communication. This study provided a better understanding of these barriers in emergency department, often neglected in most studies. It is held that by reducing environmental turmoil (physical-mental), inter-professional communication can be improved, thereby improving patient care outcomes and personnel job satisfaction.

The aim of this study was to determine the perceived verbal and physical violence and related factors experienced by nurses in emergency settings. Studies on violence in emergency departments indicate an increasing frequency of these incidents. However, little is known about the violence experienced by the Turkish nurses working in emergency departments. Survey. The study population included 255 nurses. Data were collected using a questionnaire. Verbal violence was reported with a frequency of 91.4%. Of the nurses, 74.9% had been exposed to physical violence in at least several episodes during the previous 12 months. Patients' relatives were the main perpetrators, followed by patients, most of whom were male. After experiencing violence, most of the nurses reported that, they had felt fear and only 3% described that they took sick leave, while 80% did not report the incidences of violence they experienced. The nurses described that, after a violent incident, they sought support mainly from their colleagues in emergency departments rather than from the administration. Over half of the nurses (65%) felt safe 'none of the time' in emergency departments, and 89.8% of them described that patients and patient relatives may potentially exhibit violent behaviours towards the staff when they are first admitted to emergency department, while 73.7% believed that the staffing pattern and physical environment of their emergency departments were not adequate to prevent violence. Most of the nurses (83.5%) stated that they should be provided with the training that will help them prevent and manage violence as part of their in-service education, whereas 82.7% of them had not received any such training. The findings have implications for occupational health and safety from both employer and employee perspective. © 2010 Blackwell Publishing Ltd.

In 1996 the main activities of Department P-5 (until December 1996 known as the Department of Thermonuclear Research) were concentrated on 5 topics: 1. Selected problems of plasma theory, 2. Studies of phenomena within high-current plasma concentrators, 3. Development of plasma diagnostic methods, 4. Studies in the field of fusion technology, 5. Research on new plasma-ion technologies. Theoretical studies mainly concerned elementary processes occurring within a plasma, and particularly those within near-electrode regions of microwave discharges as well as those within near-wall layers (SOL) of tokamaks. We also developed computational packages for parameter identification and modelling of physical phenomena in pulse plasma coaxial accelerators. Experimental studies were concentrated on the generation of a dense magnetized plasma in different high-current PF (Plasma Focus) facilities and small Z-Pinch devices. We carried out investigations of X-rays, relativistic electron beams (REBs), accelerated primary ions, and fast products of fusion reactions for deuterium discharges. Research on plasma diagnostics comprised the development of methods and equipment for studies of X-ray emission, pulsed electron beams, and fast ions, using special Cherenkov-type detectors of electrons and solid-state nuclear track detectors (SSNTDs) of ions. New diagnostic techniques were developed. Studies in the field of fusion technology concerned the design, construction, and testing of different high-voltage pulse generators. We also developed special opto-electronic systems for control and data transmission. Research on plasma-ion technology concentrated on the generation of pulsed high-power plasma-ion streams and their applications for the surface modification of semiconductors, pure metals and alloys. The material engineering studies were carried out in close collaboration with our P-9 Department and other domestic and foreign research centers

Full Text Available A AMAZÔNIA está entrando em uma era de rápidas mudanças impulsionadas pela previsão de asfaltamento de rodovias que estimularão a expansão da fronteira agrícola e de exploração madeireira. O declínio do custo de transporte tem importantes implicações para a biodiversidade, emissão de gases que contribuem para o efeito estufa e prosperidade da sociedade da Amazônia a longo prazo. Para analisar esse contexto, foi desenvolvido um modelo de simulação de desmatamento na bacia Amazônica, sensível a diferentes cenários de políticas públicas frente à expansão da infra-estrutura de transporte pela região. Resultados do modelo indicam que, dentro de um cenário pessimista, o desmatamento projetado pode eliminar, até meados deste século, 40% dos atuais 5,4 milhões de km² de florestas da Amazônia, liberando o equivalente a 32 Pg (10(9 toneladas de carbono para atmosfera. A modelagem de cenários alternativos aponta que a expansão de uma rede de áreas protegidas, efetivamente implementadas, poderia reduzir em até 1/3 as perdas florestais projetadas.

Research in the Physics Department at Risoe National Laboratory covers three main fields: Condensed Matter Physics, Plasma Physics and Meteorology. The principal activities in these fields for the period from 1 January to 31 December 1983 are described. The condensed matters physics research is predominantly experimental utilising diffraction of neutrons and X-rays. The research topics range from studies of structure, excitations and phase transitions in model systems to studies of ion transport, texture and recrystallization kinetics with a more applied nature.

Physical violence is defined as deliberate use of physical force likely to result in trauma, bodily injury, pain, or impairment. Present study is pioneering effort to evaluate mechanisms and sociodemographic features of physical violence targeting the elderly in Turkey and to investigate preventive measures. Database records and forensic reports were analyzed in this retrospective study of 54 elderly patients with trauma as result of physical violence who were admitted to emergency department of Şanlıurfa Training and Research Hospital between January 2012 and July 2013. Of the 54 patients evaluated, 50 (92.4%) were male. History of experiencing previous violence was described by 55.6% (n=30) of the patients. Instances of repeat violence and firearm injuries most often occurred in the home (p=0.006, p=0.007). Need for surgical treatment was also greater among cases that occurred in the home (p=0.016). Firearm injury, recurrent violence, and surgical treatment rates were higher among cases that occurred in the home. Urgent preventive measures are especially needed for the elderly who have already been victims of physical violence.

Full Text Available Emoções antecedentes ao comportamento pró-social são influenciadas pela forma como os eventos são interpretados. Estudos têm demonstrado que a atribuição de incontrolabilidade do comportamento de alguém está associada à produção de estados afetivos de simpatia ou pena. Esta asserção teórica tem sido corroborada por meio do uso de cenários de simulação experimental. O objetivo deste estudo é avaliar o efeito que a variação dos cenários, como a proximidade social do protagonista e as normas sociais subjacentes ao cenário, possuem sobre a relação atribuição-ajuda. Foi desenvolvido um estudo com 24 cenários do qual participaram 547 estudantes universitários. Os resultados indicaram que, independentemente do cenário, a percepção de incontrolabilidade levou a emoções simpáticas (ou de compaixão que, por sua vez, estão associadas a uma maior intenção de ajuda. Além disto, cenários que emulam normas de reciprocidade estão associados à maior intenção de ajudaProsocial behavior emotions are influenced by how events are interpreted. Studies have shown that the attribution of incontrolabitily to one's behavior is associated with the production of sympathy emotions. This theoretical assertion has been corroborated with experimental scenarios. This study aimed to evaluate the effect of variations of the scenarios, such as the social proximity of the protagonist and social norms have over prosocial behavior intentions. An experimental study with 24 scenarios was conducted and 547 university students took part. The results indicate that regardless of the scenario content perceived misfortune leads to sympathy or pity emotions which, in turn, are associated with greater helping intention. Reciprocity norm scenarios were associated with greater helping intentions

2005-03-01

The education and training of the workforce needed to assure global competitiveness of American industry in high technology areas, along with the proper role of various disciplines in that educational process, is currently being re-examined. Several academic areas in science and engineering have reported results from such studies that revealed several broad themes of educational need that span and cross the boundaries of science and engineering. They included greater attention to and the development of team-building skills, personal or interactive skills, creative ability, and a business or entrepreneurial where-with-all. We will report in this paper the results of a fall 2000 Department of Education FIPSE grant to implement changes in its graduate physics program to address these issues. The proposal goal was to produce next-generation physics graduate students that are trained to evaluate and overcome complex technical problems by their participation in courses emphasizing the commercialization of technology research. To produce next-generation physics graduates who have learned to work with their student colleagues for their mutual success in an industrial-like group setting. And finally, to produce graduates who can lead interdisciplinary groups in solving complex problems in their career field.

Full Text Available This article is the result of a participatory action research project aimed at providing a novel approach for the Northern Central Regional Office of the CEN CINAI [Education and Nutrition Centers (CEN and the Children’s Nutrition and Comprehensive Care Centers (CINAI] to build knowledge on an unfinished process: “Supportive Supervision” (supervisión capacitante.  Based on a naturalistic premise, we tried to answer a question that guided us in the group creation and transformation, switching our meetings from a vertical standpoint to a horizontal relationship providing accompaniment, support and construction, as well as analysis and reflection. The article shows the aspects that justified the development of the participative action research process under a methodological proposal that involves those of us who participated and contributed to build knowledge with our experience and from different locations within the Region.  A total of 29 professionals participated, willing to jointly meet a purpose: construct knowledge based on team work and on a process full of uncertainty that encourages us to constantly revise what has already been built and enables us to re-read and retake what has already been written and to systematize what could not be written before. In order words, to make this process a new way of developing knowledge that implies a more concrete standpoint to understand what “Supportive Supervision” is and how it is done, with the purpose of always looking for improvement within the National Directorate of CEN CINAI.

The Department of Atomic Physics at Plovdiv University has 40 year long experience in educating students in Atomic and Subatomic Physics. We aim at making the knowledge gained in nuclear physics part of the culture of our students. At the core of our educational activities lies our long and successful experience in studying the characteristics of atomic nuclei. In cooperation with JINR-Dubna we have studied the nuclei of approximately 40 percent of the periodic table elements. These studies also serve as a basis for the diverse implementation activities of the Department, which have an impressive geographical spread. In recent years our research has been focusing more specifically on radio-ecological issues with the valuable support of the Nuclear Regulatory Agency (NRA). Future more intense support on behalf of NRA's together with more dynamic links with other specialized units, such as the Kozloduy NPP in the first place, would considerably contribute to optimizing the effect of our overall activity.

Theoretical and experimental studies of Extensive Air Shower properties are performed mostly basing on the results obtained by the Lodz Extensive Air Shower Array. We have noticed unexplainable delayed signals registered about 500-900 microseconds after the main EAS pulse. Neutron transport simulations were performed in collaboration with JINR in Dubna. We prepared hardware for further experimental study of this effect. Continuous registrations of 5 GeV muon flux with the underground muon telescope have been carried on over the year 2001. We have detected several changes of muon intensity correlated with Forbush decreases registered at lower energies. We have also started registrations of muon counting rate in the on-surface scintillation detectors. These measurements will be included to the analysis of the disturbed energy spectrum of primary cosmic rays and its dependence on interplanetary disturbances related to the solar activity.

We aim to determine the absolute parameters of the components of southern Algol-type binaries with deep eclipses RW CrA, DX Vel, V0646 Cen and interpret their orbital period changes. The data analysis is based on a high quality Walraven photoelectric photometry, obtained in the 1960-70s, our recent CCD photometry, ASAS (Pojmanski, 2002), and Hipparcos (Perryman et al., 1997) photometry of the objects. Their light curves were analyzed using the PHOEBE program with fixed effective temperatures of the primary components, found from disentangling the Walraven (B-U) and (V-B) colour indices. We found the absolute parameters of the components of all three objects. All reliable observed times of minimum light were used to construct and analyze the Eclipse Time Variation (ETV) diagrams. We interpreted the ETV diagrams of the detached binary RW CrA and the semi-detached binary DX Vel by a LIght-Time Effect (LITE), estimated parameters of their orbits and masses of their third bodies. We suggest a long term variation of the inclination angle of both eclipsing binaries, caused by a non-coplanar orientation of their third body orbits. We interpreted the detected orbital period increase in the semi-detached binary V0646 Cen by a mass transfer from the less to more massive component with the rate M⊙ = 6.08×10-9 M⊙/yr.

Constraining the inclination of the Low-Mass X-ray Binary Cen X-4

Hammerstein, Erica K.; Cackett, Edward M.; Reynolds, Mark T.; Miller, Jon M.

2018-05-01

We present the results of ellipsoidal light curve modeling of the low mass X-ray binary Cen X-4 in order to constrain the inclination of the system and mass of the neutron star. Near-IR photometric monitoring was performed in May 2008 over a period of three nights at Magellan using PANIC. We obtain J, H and K lightcurves of Cen X-4 using differential photometry. An ellipsoidal modeling code was used to fit the phase folded light curves. The lightcurve fit which makes the least assumptions about the properties of the binary system yields an inclination of 34.9^{+4.9}_{-3.6} degrees (1σ), which is consistent with previous determinations of the system's inclination but with improved statistical uncertainties. When combined with the mass function and mass ratio, this inclination yields a neutron star mass of 1.51^{+0.40}_{-0.55} M⊙. This model allows accretion disk parameters to be free in the fitting process. Fits that do not allow for an accretion disk component in the near-IR flux gives a systematically lower inclination between approximately 33 and 34 degrees, leading to a higher mass neutron star between approximately 1.7 M⊙ and 1.8 M⊙. We discuss the implications of other assumptions made during the modeling process as well as numerous free parameters and their effects on the resulting inclination.

2005-01-01

This is a time when the whole of Europe faces energy and environmental transitions. CEE countries face in addition the challenge of implementing medium- to long-term energy reforms in order to comply with EU legislation and practices. Crucial to the proper managing of these common and fundamental concerns is the cooperation between developed and transforming countries. At a lower level this implies that problems specific to CEE countries, such as fragmentation and lack of performing resources, can be overcome through collaboration and knowledge transfer within a network of concerned and competent entities. As an organization aiming to support environmental protection by enhancing the safety and security of nuclear facilities in CEE countries, CENS is focused on being an independent forum and platform organization for the dissemination of scientific and technical knowledge and of expertise in the nuclear and energy-related communities. In seeking to achieve this objective, CENS has over the past two years provided a system of networking and international membership for nuclear regulators in CEE countries and for technical support organizations from around Europe.

A workshop was held in May 2004 in Toronto, Canada, to introduce the concept of CEN and recruit clinical cytogenetic laboratories at hospitals across the country. Slides were prepared for dicentric assay analysis following in vitro irradiation of blood to a range of gamma-ray doses. A minimum of 50 metaphases per slide were analyzed by 41 people at 22 different laboratories to estimate the exposure level. Dose estimates were calculated based on a dose response curve generated at Health Canada. There were a total of 104 dose estimates and 96 (92.3%) of them fell within the expected range using triage scoring criteria. Half of the laboratories analyzed 50 metaphases in

Full Text Available O uso inadequado dos solos agrícolas vem causando a perda gradual da sua capacidade produtiva e a degradação dos recursos hídricos por sedimentos e poluentes. O uso do solo pode afetar os processos hidrológicos e a erosão do solo na bacia. O objetivo do trabalho foi simular diferentes cenários de uso do solo para a bacia hidrográfica do ribeirão Concórdia, utilizando o modelo SWAT, e analisar os efeitos dessas mudanças no fluxo de água e de sedimentos. Os cenários gerados foram agricultura, mata nativa e pastagem. A bacia está localizada no sul do Brasil e possui uma área de drenagem de 30,74 km². Na etapa de calibração, obteve-se coeficente de eficiência Nash-Sutcliffe mensais de 0,82 para escoamento e 0,83 para sedimento. O cenário mata nativa apresentou o maior decréscimo na vazão média, em relação ao cenário atual, cerca de 8,70%. O cenário agricultura produziu a maior taxa de produção de sedimentos, aproximadamente 3 vezes maior que o cenário atual.Observou-se que alterações no uso do solo impactam o regime e a disponibilidade hídrica da bacia.

Combinando intuição e objetividade na construção de cenários alternativos Combining intuition with objectivity in building scenarios

Directory of Open Access Journals (Sweden)

José Roberto Ribas

2008-12-01

Full Text Available O planejamento por meio de cenários completou 40 anos de existência. No período compreendido entre seu surgimento, em 1967, e o final da década de 70, observou-se um esforço analítico no sentido de aprimorar a técnica como ferramenta de apoio à decisão. Tal mobilização resultou em três linhas metodológicas distintas - as escolas de lógica intuitiva, de tendências probabilísticas e de análise prospectiva. Desde então, a preferência pela adoção da técnica dos cenários no planejamento não cresceu como se esperava. A limitação no seu uso é explicada pelo sucesso moderado que seus praticantes tiveram em balancear a tecnicalidade excessiva por um lado e a superficialidade relapsa por outro. Ademais, Millett (2003 destaca a reclamação da média gerência de que os cenários não tratam das situações competitivas e tampouco das decisões críticas que eles enfrentam em seus negócios. O autor sugere alguns desafios a serem enfrentados: (a resolver a confusão sobre a definição de cenário e as metodologias para a sua construção; (b esclarecer e ampliar as aplicações apropriadas aos cenários; e (c reduzir os recursos requeridos para executar o planejamento por cenários. O presente artigo tem por objetivo propor um procedimento para a construção de cenários que atenda a esses desafios. Por meio de uma abordagem exploratória, a metodologia proposta combina o julgamento subjetivo, obtido a partir da intuição dos especialistas, com métodos analíticos. O procedimento passo a passo foi aplicado ao longo da construção dos cenários alternativos para o consumo residencial de energia elétrica, no Estado do Paraná, até o ano 2015. As entrevistas estruturadas envolveram 14 especialistas selecionados por julgamento, e as informações secundárias foram coletadas de bases de dados socioeconômicos e do setor elétrico.

The European Committee for Standardization (CEN) through its Technical Committee CEN/TC-350 is developing a series of standards for assessing the building sustainability, at both product and building levels. The practical application of the selection (decision making) of structural alternatives made by one-way slabs leads to an intermediate level between the product and the building. Thus the present study addresses this problem of decision making, following the CEN guidelines and incorporating relevant aspects of architectural design into residential construction. A life cycle assessment (LCA) is developed in order to obtain valid information for the decision making process (the LCA was developed applying CML methodology although Ecoindicator99 was used in order to facilitate the comparison of the values); this information (the carbon footprint values) is contrasted with other databases and with the information from the Environmental Product Declaration (EPD) of one of the lightening materials (expanded polystyrene), in order to validate the results. Solutions of different column disposition and geometries are evaluated in the three pillars of sustainable construction on residential construction: social, economic and environmental. The quantitative analysis of the variables used in this study enables and facilitates an objective comparison in the design stage by a responsible technician; the application of the proposed methodology reduces the possible solutions to be evaluated by the expert to 12.22% of the options in the case of low values of the column index and to 26.67% for the highest values. - Highlights: • Methodology for selection of structural alternatives in buildings with one-way slabs • Adapted to CEN guidelines (CEN/TC-350) for assessing the building sustainability • LCA is developed in order to obtain valid information for the decision making process. • Results validated comparing carbon footprint, databases and Env.

Security, a subset of safety, is equally important in the efficient delivery of patient care. The emergency department (ED) is susceptible to violence creating concerns for the safety and security of patients, staff, and visitors and for the safe and efficient delivery of care. Although there is an implicit and growing recognition of the role of the physical environment, interventions typically have been at the microlevel. The objective of this study was to identify physical design attributes that potentially influence safety and efficiency of ED operations. An exploratory, qualitative research design was adopted to examine the efficiency and safety correlates of ED physical design attributes. The study comprised a multimeasure approach involving multidisciplinary gaming, semistructured interviews, and touring interviews of frontline staff in four EDs at three hospital systems across three states. Five macro physical design attributes (issues that need to be addressed at the design stage and expensive to rectify once built) emerged from the data as factors substantially associated with security issues. They are design issues pertaining to (a) the entry zone, (b) traffic management, (c) patient room clustering, (d) centralization versus decentralization, and (e) provisions for special populations. Data from this study suggest that ED security concerns are generally associated with three sources: (a) gang-related violence, (b) dissatisfied patients, and (c) behavioral health patients. Study data show that physical design has an important role in addressing the above-mentioned concerns. Implications for ED design are outlined in the article. © The Author(s) 2016.

ESO, in collaboration with the Breakthrough Initiatives, is working to modify the Very Large Telescope mid-IR imager (VISIR) to greatly enhance its ability to search for potentially habitable planets around both components of the binary Alpha Centauri, part of the closest stellar system to the Earth. Much of the funding for the NEAR (New Earths in the Alpha Cen Region) project is provided by the Breakthrough Initiatives, and ESO mostly provides staff and observing time. The concept combines adaptive optics using the deformable secondary mirror at Unit Telescope 4, a new annular groove phase mask (AGPM) coronagraph optimised for the most sensitive spectral bandpass in the N-band, and a novel internal chopper system for noise filtering based on a concept for longer wavelengths invented by the microwave pioneer Robert Dicke. The NEAR experiment is relevant to the mid-infrared METIS instrument on the Extremely Large Telescope, as the knowledge gained and proof of concept will be transferable.

The author studies the past paths of the run-away star Zeta Oph from the OB association Sco-Cen, and of the run-away stars AE Aur, Mu Col and 53 Ari from the OB association Ori OB1, in connection with the question of the origin of these high velocities. Should the binary-hypothesis be adhered to (supernova explosion of one of the components) or, perhaps, dynamical evolution in young, dense clusters offer a clue to this phenomenon? It is shown that the latter hypothesis is very unlikely to apply to Zeta Oph. For the run-away stars from Orion conclusive evidence may well be obtained in the course of the next decade, from improved accuracy of the proper motions

An overview of SCK-CEN's technological research for the treatment of tritiated waste

International Nuclear Information System (INIS)

Braet, J.; Bruggeman, A.; Vanderbiesen, S.

2004-01-01

The production of fusion energy involves the use of huge amounts of tritium, of the order of 4 x 10 19 Bq/Gwe.a. Therefore operation and dismantling of test installations and future commercial fusion reactors are not possible without the production of tritiated waste. Various categories of tritiated waste are and will be produced which require different detritiation techniques to lower the initial tritium content in the samples and to allow final waste disposal of the partly detritiated material and of all by-products generated in the processes. The current internationally adopted strategy is to convert all kinds of tritiated waste into tritiated water, which can then be treated in one water detritiation installation. Since several years SCK-CEN has been developing techniques for the treatment of tritiated waste. Amongst them technologies for the treatment of tritiated organic liquids, surface contaminated metals, contaminated concrete and most importantly water detritiation. The so-called liquid phase catalytic exchange for water detritiation requires an efficient catalyst that should furthermore be hydrophobic because of the low solubility and hence slow diffusion of hydrogen in the water layer that covers normal catalysts. In the past SCK-CEN invented and developed such a catalyst which has recently been optimized and tested in a bench scale installation. To confirm the performances of our improved catalyst for a longer period of time and in a longer column, we are now doing tests in a 2 meter high trickle bed reactor and the endurance of the catalyst is being tested at ICSI. Using a good performing catalyst, LPCE will be, in combination with electrolysis, a technically and economically sound technology for water detritiation. Other R and D focuses on the development of a system do decontaminate surface contaminated metals and concrete using superheated steam. The resulting water can in its turn be treated in a water detritiation installation. For the purpose of

Full text: The activities of the Department in 2007 continued previous studies in the following fields of plasma physics, controlled nuclear fusion and plasma technology of surface engineering: · Studies of physical phenomena in pulsed discharges in the Plasma-Focus (PF) and RPI-IBIS facilities; · Development of selected methods for high-temperature plasma diagnostics; · Research on plasma technologies; · Selected problems of plasma theory and computational modelling. As for the experimental studies particular attention was paid to the analysis of the correlation of X-ray pulses with pulsed electron beams and other corpuscular emissions from different Plasma-Focus (PF) facilities. A collisional-radiative model, taking into account the Stark effect and strong electric fields in the so called '' hot- spot '' regions of a pinch, was applied in those analyses. The main aim of these studies was to identify the physical phenomena responsible for the emission during the PF-type discharges. The emitted protons were also measured with nuclear track detectors. The measurements made it possible to obtain images of the regions, where the D-D fusion reactions occurred, as well as to determine the angular distribution of the emitted protons. Pulsed plasma streams were also investigated by means of time-resolved optical spectroscopy and corpuscular diagnostics. In a frame of the EURATOM program, efforts were devoted to the development of diagnostic methods for tokamak-type facilities. Such studies include the design and construction of the 4-channel Cherenkov-type detection system for the TORE-SUPRA tokamak at CEA-Cadarache. In the meantime in order to collect some experience a new measuring head was especially prepared for experiments within small facilities. Other fusion- oriented efforts are connected with the application of the solid-state nuclear track detectors for investigation of protons from tokamak plasma and high-energy beams emitted from laser produced plasmas

Managing Nuclear Knowledge: a challenge for SCK-CEN

International Nuclear Information System (INIS)

Ruyssen, M.-L.

2005-01-01

All innovation in nuclear science and nuclear technology for either power or non-power applications relies on knowledge. Preserving and enhancing nuclear knowledge accumulated in the past has become a timely subject of strategic importance. In recent years, political, economical and societal trends urged the need for an efficient management of nuclear knowledge. Foremost, the Belgian government has decided to phase-out nuclear power plants. Privatisation and deregulation rules of the energy market in the European Union drives the nuclear industry to compete in the immediate and near term with other sources of electrical energy. This might result in a reduction of work force and budgets allocated to research and development. These two decisions have as a side effect that fewer young people are attracted by studying nuclear science and nuclear engineering, making the issue of the replacement of the aging nuclear workforce even worse. This changing environment requires therefore the pro-active retention and preservation of our comprehensive nuclear knowledge base and the sustainment of our nuclear education and training efforts. SCK-CEN's initiatives concerning preserving and sharing Nuclear Knowledge and sustaining nuclear education and training are discussed

We present deep and accurate photometry (F435W, F625W, F658N) of the Galactic Globular Cluster omega Cen collected with the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope (HST). We identified ≈ 6,500 white dwarf (WD) candidates and compared their radial distribution with that of Main Sequence (MS) stars. We found a mild evidence that young WDs ( 0.1 ≲ t ≲ 0.6 Gyr) are less centrally concentrated when compared to MS stars in the magnitude range 25 < F435W < 26.5.

Full text: The activity of the Department of Nuclear Methods in the Solid State Physics is focused on experimental research in condensed matter physics. Thermal neutron scattering and Moessbauer effect are the main techniques mastered in the laboratory. Most of the studies aim at better understanding of properties and processes observed in modern materials. Some applied research and theoretical studies were also performed. Research activities of the Department in 2001 can be summarized as follows: Neutron scattering studies concerned the magnetic ordering in TbB 12 and TmIn 3 and some special features of magnetic excitations in antiferromagnetic γ-Mn-alloys. Some work was devoted to optimization of the neutron single crystal monochromators and polarizers grown in Crystal Growth Laboratory. Small angle scattering studies on the surfactant - water ternary system were performed in cooperation with JINR Dubna. Moessbauer effect investigations of dysprosium intermetallic compounds yielded the new data for Pauling-Slater curves. The same technique applied to perovskites and ferrocene adduct to fullerene helped to resolve their structure. X-ray topographic and diffractometric studies were performed on hydrogen implanted semiconductor surfaces employing the synchrotron radiation sources. The X-ray method was applied also to investigations of plasma spraying process and phase composition of ceramic oxide coatings. Large part of studies concerned the structure of biologically active, pharmacologically important organic complexes, supported by modeling of their electron structure. Crystal growth of large size single-crystals of metals and alloys was used for preparation of specimens with mosaic structure suitable for neutron monochromator and polarizer systems. The construction work of the Neutron and Gamma Radiography Station has been completed. The results of first tests and studies proved the expected abilities of the systems.

2004-01-01

The century covered by this book has seen scientific developments unprecedented in human history, so an endeavour has been made to describe something of the careers in physics of our departmental members past and present. The prologue tells of the lack of decisions, academic and governmental, which delayed until 1904 the arrival of the first university professors, who even then could be appointed only through a private benefaction. Chapters I-IV give the general development from 1904 to the present while Chapter V describes the work of the major groups in the department. A review of each group is followed by a brief selection of the work of the individual members. Few, if any, can hope to keep up with the many facets of the subject today, so a glimpse at what is going on at the cutting edge of the whole field may reveal something of the state of physics at the beginning of the twenty-first century. The final chapter (VI) tells of the department's service and outreach beyond the classroom and the honours and awards gained by the individual members.

The DAPNIA is a department of CEA, its main characteristic is to manage scientific teams working on astrophysics, nuclear physics, elementary particles and instrumentation. Every 2 years DAPNIA's activities are submitted to an evaluation made by a scientific committee whose members are experts independent from CEA. This committee reviews the work done, gives an opinion about the options chosen for the projects to come and writes out a report. In 1997 the committee had a very positive opinion of the work done by DAPNIA teams. The contributions to various and important national or international programs have been successful, we can quote: Ulysse mission, soho, iso, integral for spatial programs, aleph, delphi, H1 at Hera, atlas, cms, na48, nomad, babar, antares for particle physics and spiral, smc, compass for nuclear physics. The committee advises DAPNIA to favour more contacts between the theoreticians and the experimentalists who work on quantum chromodynamics and hadron physics. The committee shows its concern about improving the balance between the means dedicated to instrumentation designing and those dedicated to the analysis and interpretation of the experimental data collected.

The first part of this article describes the instruments available at the Standard Temperature Calibration Center of the CEN Saclay. At the moment the Center has been approved by the BNM to make calibrations between 0 and 1050 0 C, but the Center has recently developed some ovens which will allow calibrations up to 2000 0 C. The Center can also perform thermal and mechanical tests on detector components under the influence of external factors. The second part concerns the development of platinum-resistance high temperature thermometer. The calibrations by comparison between 0 and 1000 0 C are, at the moment, made by using platinum resistance thermometer as a reference up to 630 0 C and a platinum-rhodied/platinum thermocouple above 630 0 C. The use of only one reference could represent for a calibration center a great improvement. For this reason a platinum-resistance high temperature thermometer has been developed. Great care was taken during the conceptual design and during the selection and the assembly of each component [fr

taking part in the proficiency test on the determination of 239 Pu, 241 Pu and 241 Am in mineral matrix, organised by the IAEA. Ten dust samples, delivered by the University of Bremen (Germany) were analysed for the presence of 238 Pu, 239+240 Pu, 241 Pu, 241 Am and 244 Cm. In 1999, the equipment of the Environmental Radioactivity Laboratory was enriched with a low- background liquid scintillator spectrometer (Wallac 1414-003 Guardian), which opened a whole new branch of possible work connected with determination of pure beta-emitters. First isotopes of interest were 90 Sr and 241 Pu accumulated in animal bones. For 90 Sr measurements, an extensive library of scintillation quenching corrections was prepared. The spectrometer was also applied for tests of the purity of 32 P for the Laboratory of Physical Chemistry. A new project on transfer of plutonium from forest soil and litter to fungi and plants has been started. It is a pilot study for a planned in-Lab experiment to be performed during the incoming year at the University of Extremadura, Caceres, Spain. Other projects conducted during 1999 in the Environmental Radioactivity Laboratory are described in short abstracts below. In the Laboratory of Physical Chemistry, the project on construction of the internal target assembly for isotope production was continued, in cooperation with the Institute's Division of Mechanical Construction and with the Cyclotron Section. At the same time, much investment was made into necessary renovations in the radiochemical laboratory. Research in the Laboratory was concentrated on preparation and evaluation of 32 P sources for intravascular brachytherapy. With the help of the Institute's Health Physics Laboratory, liquid Na 2 H 32 PO 4 sources were calibrated by TL dosimetry, and in cooperation with the Department of Nuclear Spectroscopy, some solid state sources containing 32 P were prepared. Liquid 32 P sources calibrated in the Institute were first applied in pre-clinical intravascular

Fermi LAT has detected gamma ray emissions from the core of Cen A. More recently, a new component in the gamma ray spectrum from the core has been reported in the energy range of 4 GeV to tens of GeV. We show that the new component and the HESS detected spectrum of gamma rays from the core at higher energy have possibly a common origin in photo-disintegration of heavy nuclei. Assuming the cosmic rays are mostly Fe nuclei inside the core and their spectrum has a low energy cut-off at 52 TeV in the wind frame moving with a Doppler factor 0.25 with respect to the observer on earth, the cosmic ray luminosity required to explain the observed gamma ray flux above 1 GeV is found to be 1.5 × 10{sup 43} erg/sec.

The activities of Department P-10 in 2006 were as follows: - continuation of development of radiographic 5-6 MeV electron accelerator, - study of very compact accelerating standing wave RF structures for electrons and ions, - Monte Carlo simulations applied to ion radiotherapy. The compact 6 MeV electron linac constructed in Department P-10 were further developed. Some equipment (low input impedance amplifier for beam transformer, up-to-date power supplies for beam position steering coils, magnetron frequency control unit) was added or replaced. The old control racks were replaced by a new single more compact control console. This will allow us to introduce a PLC based control system of accelerator (when money for necessary PLCs is granted). After additional amelioration of radiation shielding followed by Radiological Inspection, the permanent permission No D-15917 for routine operation of this accelerator in electron and X-ray mode was issued by the National Atomic Energy Agency. This allows us to render services to external customers. As it was already reported in 2005, two regimes of operation are actually possible: with X ray output beam or electron beam, depending on user demand. The triode gun, originally thought of as a part of the 6/15 MeV medical accelerator is still showing excellent performance on experimental stand; it was opened to air for about 2 hours to repair the broken wire of the beam scanner. This confirms the possibility of repeated formation of gun dispenser cathode. A new pulse modulator was routinely used in these tests. The special set-up, designed and made in our Department for the TiN coating of accelerator components, was routinely used for coating of various types of RF high power vacuum windows for conventional and superconducting 1.3 GHz accelerating structures. Cooperation with foreign enterprises is promising. Accel Instruments GmbH ordered the coating of two sets (in total 18 pieces) of coaxial and cylindrical vacuum windows for

The activities of P-10 Department in year 2005 were devoted to: - development of radiographic 4 MeV electron accelerator, - development of accelerating and deflecting types travelling (TW) and standing wave (SW) RF structures for electrons and ions, - MC simulations applied to photon and ion radiotherapy The compact 6 MeV electron linac constructed in Department P-10 was put in the beginning of reported year into experimental operation. The request for permission to use ionisation source (6 MeV linac) was submitted to National Atomic Energy Agency. On the basis of all necessary documents the permission for routine using of our linac was granted. Actually the e/X conversion tungsten target has been moved from vacuum to air. To improve the safety of accelerator operation, the new collimator and some shielding walls were added. Two regimes of operation are actually possible: X ray output beam or electron beam depending on user demand. Some old non-reliable sub-units of accelerator were replaced, and energy and intensity optimisation for e-/X-ray conversion were made. The MC calculations of photon beams produced on e-/X converter were repeated taking into account the new collimator and additional shields. The triode gun, originally thought of as a part of 6/15 MeV medical accelerator is still on long term tests showing excellent performance; it was twice opened to air to confirm the possibility of repeated formation of gun dispenser cathode. New pulse modulator was routinely used in these tests. The sublimation set-up designed and made in our Department for the TiN coating of accelerator components underwent successfully the technological test including coating quality of several ceramic RF power vacuum windows. Within the German heavy ion therapy program the DKFZ Heidelberg is responsible for medical physics problems of treatment planning and modeling of ion beams for GSI Radiotherapy Facility. The MC simulations are used to calibrate the X-ray CT scanners to obtain

The first centromeric protein identified in any species was CENP-A, a divergent member of the histone H3 family that was recognised by autoantibodies from patients with scleroderma-spectrum disease. It has recently been suggested to rename this protein CenH3. Here, we argue that the original name should be maintained both because it is the basis of a long established nomenclature for centromere proteins and because it avoids confusion due to the presence of canonical histone H3 at centromeres.

Full Text Available Foreign students study physics and Russian as a foreign language at the preparatory Department. They are to be trained to study different courses. During only one year the teachers of physics and Russian should help students from Asia, Africa and Latin America to get ready to study in the university. To help students in a short time to learn physical terms, to understand physics by ear, to read and write, teachers are developing the online multimedia tutorial. It is placed on the cloud OneDrive. Tutorial includes the main themes in the Mechanics. They are physical processes and phenomena, units, physical quantities, kinematics, laws of mechanics and others. The Power Point presentation slides contain information on the topics. These slides help students learn to read Russian texts on physics. There are hyperlinks to sound files on slides. Listening to those recordings, students gain the skills of physical texts listening. After each module we placed the test. Students can prepare for it using the simulator. Tests and exercise equipment made in the form of EXCEL spreadsheets. We provide our students the opportunity to view, read and listen, the tutorial files via their own mobile devices. Thus they can study physics in Russian in the classroom, or at home, but in the library, in the Park etc. Also they have access to it when they are not in Russia, and in their native countries. The tutorial presented seems to be considered as the first attempt to develop the online multimedia aimed to assist foreign students to get success in their efforts to study physics in Russian. It helps our students to learn physics in Russian faster and better. Determined are the directions of further development and improvement of the tutorial.

Physical design correlates of efficiency and safety in emergency departments: a qualitative examination.

Pati, Debajyoti; Harvey, Thomas E; Pati, Sipra

2014-01-01

The objective of this study was to explore and identify physical design correlates of safety and efficiency in emergency department (ED) operations. This study adopted an exploratory, multimeasure approach to (1) examine the interactions between ED operations and physical design at 4 sites and (2) identify domains of physical design decision-making that potentially influence efficiency and safety. Multidisciplinary gaming and semistructured interviews were conducted with stakeholders at each site. Study data suggest that 16 domains of physical design decisions influence safety, efficiency, or both. These include (1) entrance and patient waiting, (2) traffic management, (3) subwaiting or internal waiting areas, (4) triage, (5) examination/treatment area configuration, (6) examination/treatment area centralization versus decentralization, (7) examination/treatment room standardization, (8) adequate space, (9) nurse work space, (10) physician work space, (11) adjacencies and access, (12) equipment room, (13) psych room, (14) staff de-stressing room, (15) hallway width, and (16) results waiting area. Safety and efficiency from a physical environment perspective in ED design are mutually reinforcing concepts--enhancing efficiency bears positive implications for safety. Furthermore, safety and security emerged as correlated concepts, with security issues bearing implications for safety, thereby suggesting important associations between safety, security, and efficiency.

Twelve hundred days of 3-6 keV X-ray data from Her X-1, Vela X-1 and Cen X-3 accumulated with the Ariel-5 all-sky monitor are interrogated. The binary periodicities of all three can be clearly observed, as can the approximately 35-d variation of Her X-1, for which we can refine the period to 34.875 plus or minus .030-d. No such longer-term periodicity less than 200-d is observed from Vela X-1. The 26.6-d low-state recurrence period for Cen X-3 previously suggested is not observed, but a 43.0-d candidate periodicity is found which may be consistent with the precession of an accretion disk in that system. The present results are illustrative of the long-term studies which can be performed on approximately 50 sources over a temporal base which will ultimately extend to at least 1800 days.

VBLUM photometry of RR Lyrae stars in ω Cen and M4

DeBruijn, J.W.; Lub, J.

1987-01-01

Multicolour VBLUW photometry of RR Lyrae stars in the globular clusters M4 and ω Cen is used to derive information on reddening, blanketing, effective temperatures and gravity of these stars. The methods employed in the literature to determine the reddening of globular clusters from the UBV colours of the RR Lyrae stars are in complete agreement with the results from VBLUW photometry. The most important conclusions of the present work are: the close similarity between the RR Lyrae variables in the field and in globular clusters, and the agreement between the reddenings derived for RR Lyrae in the field and in globular clusters. This means that at least one parameter which normally is taken as a free parameter in studying globular cluster colour magnitude diagrams can be constrained very precisely

[Purpose] The purpose of this study is to examine prejudices and attitudes of students in the department of physical therapy, in order to suggest basic data for constructing an effective program to develop a positive attitude toward people with disabilities and lower social distance from them. [Subjects and Methods] For this study, students in the department of physical therapy participate in the survey examining prejudices and attitude towards people with disabilities. [Results] First, there were statistically significant differences in the prejudice against people with disabilities among student groups divided by whether they had contact on a frequent basis currently with those who have disabilities. Second, there were statistically significant differences in the prejudice against people with disabilities among student groups divided by whether they had an experience of being harmed by people with disabilities. Third, there was a correlation among prejudices against people with disabilities with each other that is articulated in the eighth domain. Finally, as a result of regression analysis, the students' attitudes towards people with disabilities were explained appropriately by the prejudices about performance of daily tasks and NIMBY (Not In My Back Yard) syndrome. [Conclusion] It is crucial to create an environment where University students in the department of physical therapy can have positive interactions with people with disabilities, to reduce the overall prejudices, and specifically, the prejudices about performance of daily tasks and about NIMBY syndrome.

Full text: In 2010 the activities of the Department continued previous studies in the following fields of plasma physics, controlled nuclear fusion and plasma engineering: · · Development of selected methods for high-temperature plasma diagnostics; · Studies of physical phenomena in pulsed discharges in the Plasma-Focus (PF), RPI-IBIS, and Impulse Plasma Deposition (IPD) facilities; · Research on plasma technologies; · Selected problems of plasma theory and computational modeling. In the frame of the EURATOM program, efforts were devoted to the development of diagnostics methods for tokamak-type facilities. In 2010 Cherenkov detectors were applied in the ISTTOK and TORE SUPRA facilities to detect energetic electrons (of energy > 60 keV), to determine their spatial and temporal behavior and to estimate their energy spectra. Attention was also paid to measurements of hard X rays emitted from ISTTOK and to their correlations with run-away electrons. The new data on fast electrons, collected within the TORE-SUPRA machine in 2010, confirmed the appearance of intense electron streams (possible ripple-born and runaway ones), which have a similar character to the electron signals recorded by means of other diagnostic techniques. Other fusion-oriented efforts are connected with the application of solid-state nuclear track detectors to detect fast alpha particles in tokamak experiments. As for experimental studies, particular attention was paid to the investigation of fast ion- and electron-beams emitted from high-current plasma discharges in PF and RPI facilities. Ion streams from discharges were studied by means of nuclear track detector, corpuscular diagnostic techniques, and particularly of a miniature Thompson-type mass-spectrometer. A field of research activity was related to plasma technology. Efforts were undertaken to improve the ultra-high vacuum (UHV) deposition of thin superconducting layers, e.g. pure niobium film on the surface of copper resonant cavities

Full Text Available A vantagem competitiva de uma empresa de manufatura em uma economia globalizada está diretamente relacionada com sua capacidade de introduzir novos produtos no mercado, garantindo linhas de produtos atualizadas tecnologicamente e com características de desempenho, custo e distribuição condizentes com o atual nível de exigência dos consumidores. Contudo, uma grande dificuldade do gerenciamento integrado do processo de desenvolvimento de produtos é a existência de poucos profissionais capacitados a atuar eficientemente nesse processo de negócio caracterizado como multifuncional. Ou seja, profissionais possuidores de uma visão ampla e integrada deste processo. Uma forma de auxiliar esta capacitação profissional baseia-se na utilização de uma nova abordagem de aprendizagem caracterizada pela didática ativa, denominada cenário. Tal abordagem é suportada por modelos de referência, a partir dos quais se pode obter os conhecimentos necessários à execução do processo de negócio. Neste contexto, este artigo tem como objetivo abordar a questão da capacitação profissional relacionada ao desenvolvimento de produtos, empregando a abordagem de cenário. O artigo não só apresenta a caracterização do processo de desenvolvimento de produtos e seus requisitos para capacitação, como também descreve um caso prático de capacitação profissional realizado em uma empresa multinacional no Brasil, utilizando a abordagem de cenário e o método científico da pesquisa-ação.

Full Text Available Este estudo objetivou analisar a importância das Áreas de Preservação Permanente (APP para a manutenção dos remanescentes florestais no município de Sorocaba, SP. O mapa desses remanescentes foi elaborado com base em fotografias aéreas de 2006, e mapas de hidrografia e de declividade foram usados para determinação das APP. Compararam-se dois cenários: real (mata atual e ideal (mata atual acrescida da restauração das APP, com base em métricas da paisagem. Os resultados indicaram que 19% do município se enquadra como APP e, dessa área, apenas 45% possui cobertura florestal. As APP preservadas representam 50% do total de cobertura florestal da paisagem. A restauração das APP representaria aumento de 16,68% para 28% de cobertura florestal da paisagem e possibilitaria o surgimento de fragmentos maiores que 3.000 ha, enquanto no cenário real os maiores fragmentos atingem 300 ha. Os remanescentes florestais se apresentaram intimamente ligados às APP: margens de rios, áreas alagáveis e encostas, onde a ocupação urbana foi dificultada e existe o instrumento legal de proteção. Esse quadro evidencia que as APP possuem papel fundamental na conservação florestal em um município bastante urbanizado, onde as áreas naturais sofrem muita pressão. A avaliação dos cenários mostrou que a incorporação dos dispositivos legais no planejamento e ordenamento territorial subsidia as estratégias voltadas para a manutenção de hábitats naturais e, consequentemente, a diminuição dos efeitos negativos sobre a biodiversidade. Entretanto, as mudanças recentes no Código Florestal podem representar um retrocesso no cenário ambiental nacional diante da crescente urbanização.

2006-01-01

In 2005 research activities in Department P-V were concentrated on the continuation of previous studies in the field of plasma physics and CNF, but new investigations were also undertaken, particularly in the field of plasma technology. The main tasks were as follows: 1. Studies of physical phenomena in pulsed discharges producing dense magnetized plasma; 2. Development of methods and tools for high-temperature plasma diagnostics; 3. Research in the field of plasma technologies. As to the first task, particular attention was paid to studies of X-ray pulses and pulsed electron beams, by means of different diagnostic techniques. Measurements of the polarization of the selected X-ray spectral lines and their correlation with pulsed e-beams were performed in the MAJA-PF facility. Taking into account microscopic irreproducibility of so-called 'hot-spots', particular efforts were devoted to the correlation of the X-ray emission from a single hot-spot with corresponding non-thermal electron pulses. Some observations of X-rays were performed also at the PF-1000 facility at IPPLM in Warsaw. Other studies concerned the correlation of fast-neutron pulses with X-rays and other corpuscular emissions. Results of experimental studies carried out in the IPJ-IPPLM collaboration were analyzed and summarized. New measurements, carried out in the MAJA-PF facility, determined the temporal correlation of X-rays pulses, fusion-neutrons, fast electron beams and high-energy ion beams. Other efforts concerned studies of fast (ripple-born) electrons in tokamaks. An analysis of the capability of special Cerenkov-type detectors (based on diamond-crystal radiators) was performed, and measuring heads for the CASTOR and TORE-SUPRA facilities have been designed. Concerning the development of plasma diagnostic techniques, characteristics of PM-355 nuclear track detectors were analyzed and the calibrated detectors (with appropriate absorption filters) were used for measurements of fast (> 3 Me

First results of the deployment of a SoLid detector module at the SCK•CEN BR2 reactor

Ryder, N.

The SoLid experiment aims to resolve the reactor neutrino anomaly by searching for electron-to-sterile anti-neutrino oscillations. The search will be performed between 5.5 and 10 m from the highly enriched uranium core of the BR2 reactor at SCK-CEN. The experiment utilises a novel approach to anti-neutrino detection based on a highly segmented, composite scintillator detector design. High experimental sensitivity can be achieved using a combination of high neutron-gamma discrimination using 6 LiF:ZnS(Ag) and precise localisation of the inverse beta decay products. This compact detector system requires limited passive shielding as it relies on spacial topology to determine the different classes of backgrounds. The first full scale, 288 kg, detector module was deployed at the BR2 reactor in November 2014. A phased three tonne experimental deployment will begin in the second half of 2016, allowing a precise search for oscillations that will resolve the reactor anomaly using a three tonne detector running for three years. In this talk the novel detector design is explained and initial detector performance results from the module level deployment are presented along with an estimation of the physics reach of the next phase.

Lucon, E

1999-04-01

This document describes the experimental and analytical procedures which have been adopted at the laboratories of the Belgian Nuclear Research Centre SCK-CEN for performing dynamic toughness tests on pre-cracked Charpy-V specimens. Such procedures were chosen on the basis of the existing literature on the subject, with several updates in the data analysis stages which reflect more recent developments in fracture toughness testing. Qualification tests have been carried out on PCCv specimens of JRQ steel, in order to assess the reliability of the results obtained; straightforward comparisons with reference data have been performed, as well as more advanced analyses using the Master Curve approach. Aspects related to machine compliance and dynamic tup calibration have also been addressed.

Full text: Research in the Department of Nuclear Physical Chemistry concentrates on three main topics: 1. Radiochemistry of transactinide elements; 2. Environmental radioactivity and related problems; 3. Preparation and applications of radioactive isotopes. The investigations on radiochemistry of transactinide elements are carried out in the Laboratory of Chemistry and Radiochemistry. Practical difficulties due to short half-lives and very low cross sections of formation of the superheavy nuclei are being overcome by developing fast and efficient methods of chemical separation, basing mostly on ion-exchange processes which are thoroughly studied via model experiments on lighter homologues of the elements of interest. During the year 2001, work with composite ferrocyanide sorbents was continued, and the efforts resulted in a patent application. The developed ion-exchangers (whose characteristics are constantly checked and improved in the laboratory) can find practical applications in environmental protection as well as in fundamental studies on the most exotic elements: 104 Rf, 105 Db, 106 Sg, 107 Bh, 108 Hs, and more. As to the latter, the discovery in Dubna of the relatively long-lived element 114 (t 1/2 =30s) gives hope that studies on aqueous chemistry of the elements Z =107 would be feasible. In this context, chemical methods of separation and identification of the heaviest elements are necessary to know the behaviour of the whole decay chains, for example: 114 -α-112 -α-110 -α-108 -α-106. The group is contributing its expertise to the top specialist international co-operation, involving the Joint Institute of Nuclear Research, Dubna, Russia, the Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, Moscow, Russia, and three German institutions: the Technical University of Dresden, the University of Mainz, and the GSI Darmstadt.

Full Text Available Abstract Background The eligibility of breast cancer patients for human epidermal growth factor receptor 2 (HER2-directed therapies is determined by the HER2 gene amplification and/or HER2 protein overexpression status of the breast tumor as determined by in situ hybridization (ISH or immunohistochemistry (IHC, respectively. Our objective was to combine the US Food and Drug Administration (FDA-approved HER2 & chromosome 17 centromere (CEN17 brightfield ISH (BISH and HER2 IHC assays into a single automated HER2 gene-protein assay allowing simultaneous detection of all three targets in a single tissue section. Methods The HER2 gene-protein assay was optimized using formalin-fixed, paraffin-embedded (FFPE samples of the xenograft tumors MCF7 [HER2 negative (non-amplified gene, protein negative] and Calu-3 [HER2 positive (amplified gene, protein positive]. HER2 IHC was performed using a rabbit monoclonal anti-HER2 antibody (clone 4B5 and a conventional 3,3'-diaminobenzidine IHC detection. The HER2 & CEN17 BISH signals were visualized using horseradish peroxidase-based silver and alkaline phosphatase-based red detection systems, respectively with a cocktail of 2,4-dinitrophenyl-labeled HER2 and digoxigenin-labeled CEN17 probes. The performance of the gene-protein assay on tissue microarray slides containing 189 randomly selected FFPE clinical breast cancer tissue cores was compared to that of the separate HER2 IHC and HER2 & CEN17 BISH assays. Results HER2 protein detection was optimal when the HER2 IHC protocol was used before (rather than after the BISH protocol. The sequential use of HER2 IHC and HER2 & CEN17 BISH detection steps on FFPE xenograft tumor sections appropriately co-localized the HER2 protein, HER2 gene, and CEN17 signals after mitigating the silver background staining by using a naphthol phosphate-containing hybridization buffer for the hybridization step. The HER2 protein and HER2 gene status obtained using the multiplex HER2 gene

Facilitating data entry, eliminating redundant effort and providing decision support are some of the factors upon which the successful uptake of Electronic Healthcare Record (EHCR) technology is dependent. The European Standardization Committee (CEN), on the other hand, has proposed a standard EHCR architecture, which allows patient record contents to be highly diverse, customized to individual user needs; this makes their processing a challenging task and poses a demand for specially designed mechanisms. We describe the requirements for a macro-directive mechanism, pertaining to CEN-compatible EHCR software that can automate updating and processing of patient records, thus enhancing the functionality of the software. We have implemented the above-mentioned mechanism in an EHCR application that has been customized for use in the care process of patients suffering from beta-Thalassemia. The application is being used during the last two years in the Thalassemia units of four Greek hospitals, as part of their every day practice. We report on the experience we have acquired so far.

Full Text Available This paper investigates the impacts of the current economic developments, the Euro adoption, and input prices on the consumer food prices. The focus of the analysis is on the consumer food price developments during the Slovenian adjustments towards the European Union membership, the Euro adoption by the followed increased in consumer prices, and the current economic and financial conditions. The empirical analysis on the determinants of the consumer food prices is based on the monthly statistical data, which were obtained from the Statistical Office of Republic of Slovenia. We use three statistical methods of the analyses on the time-series data: principal component analysis, regression analysis, and linear trend analysis. We found that the Euro adoption had only short-term impact on the consumer food prices. The rise in the consumer food prices has been determined by the intermediary costs and the agricultural producers` prices.

NEAR-INFRARED SPECTROSCOPY OF LOW-MASS X-RAY BINARIES: ACCRETION DISK CONTAMINATION AND COMPACT OBJECT MASS DETERMINATION IN V404 Cyg AND Cen X-4

International Nuclear Information System (INIS)

Khargharia, Juthika; Froning, Cynthia S.; Robinson, Edward L.

2010-01-01

We present near-infrared (NIR) broadband (0.80-2.42 μm) spectroscopy of two low-mass X-ray binaries: V404 Cyg and Cen X-4. One important parameter required in the determination of the mass of the compact objects in these systems is the binary inclination. We can determine the inclination by modeling the ellipsoidal modulations of the Roche-lobe filling donor star, but the contamination of the donor star light from other components of the binary, particularly the accretion disk, must be taken into account. To this end, we determined the donor star contribution to the infrared flux by comparing the spectra of V404 Cyg and Cen X-4 to those of various field K-stars of known spectral type. For V404 Cyg, we determined that the donor star has a spectral type of K3 III. We determined the fractional donor contribution to the NIR flux in the H and K bands as 0.98 ± 0.05 and 0.97 ± 0.09, respectively. We remodeled the H-band light curve from Sanwal et al. after correcting for the donor star contribution to obtain a new value for the binary inclination. From this, we determined the mass of the black hole in V404 Cyg to be M BH = 9.0 +0.2 -0.6 M sun . We performed the same spectral analysis for Cen X-4 and found the spectral type of the donor star to be in the range K5-M1 V. The donor star contribution in Cen X-4 is 0.94 ± 0.14 in the H band while in the K band, the accretion disk can contribute up to 10% of the infrared flux. We remodeled the H-band light curve from Shahbaz et al., again correcting for the fractional contribution of the donor star to obtain the inclination. From this, we determined the mass of the neutron star as M NS = 1.5 +0.1 -0.4 M sun . However, the masses obtained for both systems should be viewed with some caution since contemporaneous light curve and spectral data are required to obtain definitive masses.

Certain nuclear activities may have an impact on man and the environment. To understand the precise magnitude of the effect, one must first understand the distribution and behaviour of radioactive substances in the environment. This knowledge is also necessary in order to take appropriate measures to reduce radiation exposure. analysing the environmental effects of MYRRHA and of waste disposal facilities are just some of the applications of SCK-CEN biosphere impact studies.

A multisectoral model promoting sociocultural environmental change to increase physical activity levels among African Americans in Los Angeles County, California, was developed and implemented. This model represents a true collaboration between a local health department and a community lead agency. Community organizations serving targeted areas of the county participated in one or more interventions incorporating physical activity into routine organizational practice, which centered around modeling the behaviors promoted ("walking the talk"). In the current study, level of organizational support for physical activity integration was assessed, as reflected in the extent of organizational commitment associated with each intervention. Individual-level data, characterizing the sociodemography, health status, and health behaviors of organization staff, members, and clients, are presented to document the average risk burden in the targeted population. Nearly half of the more than 200 participating organizations actively embraced incorporating physical activity into their regular work routines, with more than 25 percent committed at the highest level of involvement. Broad capacity and support for organizational integration of physical activity was demonstrated, with the observed level of commitment varying by organization type. Similar to the successful evolution of tobacco control, some of the responsibility ("cost") for physical activity adoption and maintenance can and should be shifted from the individual to organizational entities, such as workplaces.

Scientometric data. The Department of Nuclear Physics and the field of cluster radioactivities

The first attempts to make a quantitative evaluation of scientific activity in the Department of Nuclear Physics date from the seventies. Progress Reports for two-year period have been published regularly since 1972. On this basis we are now able to follow the evolution of the number and visibility of the publications. The number of articles published in refereed journals per graduated person was around 0.4 per year; after 1990 it increases rapidly over unity, reflecting not only the local efforts but also the increased contributions of international cooperation. Similar evolution can be noticed for participation with invited talks, oral contributions and posters at various scientific international conferences, workshops, and summer schools. For the field of cluster radioactivities, which has been opened by a team of researchers from our Institute and the Institute of Theoretical Physics of the Frankfurt am Main University, we can give some specific examples of the most cited publications, showing that their impact during a certain period of time, has been much stronger than mean value of the impact parameter of the corresponding journals.

Full Text Available Physical design of the emergency department (ED has an important effect on its role and function. To date, no guidelines have been introduced to set the standards for the construction of EDs in Iran. In this study we aim to devise an easy-to-use tool based on the available literature and expert opinion for the quick and effective assessment of EDs in regards to their physical design. For this purpose, based on current literature on emergency design, a comprehensive checklist was developed.  Then, this checklist was analyzed by a panel consisting of heads of three major EDs and contradicting items were decided. Overall 178 crude items were derived from available literature. The Items were categorized in to three major domains of Physical space, Equipment, and Accessibility. The final checklist approved by the panel consisted of 163 items categorized into six domains. Each item was phrased as a “Yes or No” question for ease of analysis, meaning that the criterion is either met or not.

In this paper, the doses, due to food consumption, received by three villages placed around CEN Juragua (at present under construction) are calculated in the emplacement zone of the Nuclear Center (15 Km. around the facility). The selected villages have different food habits, so they receive different irradiation levels. The ingestion rate of food, the natural radionuclide concentrations existing in the environment (Cs-137, Sr-90, Ra-226, Th-232, Po-210 and Pb-210) and the dose conversion factors given by the International Commission on Radiological Protection (ICRP) were used in the assessment. More than 300 analysis carried out in a period of 6 years were compiled for the study. The doses received by people of Castillo del Jagua are analyzed in detail because they are high consumer of marine products. Groups of people receiving annual dose around 1 mSv, only by this kind of foods, were detected. (authors). 5 refs., 5 tabs

Screening markers are used in emergency departments (EDs) to identify children who should be assessed for possible physical abuse and neglect. We conducted three systematic reviews evaluating age, repeat attendance and injury type as markers for physical abuse or neglect in injured children attending EDs. We included studies comparing markers in physically abused or neglected children and non-abused injured children attending ED or hospital. We calculated likelihood ratios (LRs) for age group, repeat attendance and injury type (head injury, bruises, fractures, burns or other). Given the low prevalence of abuse or neglect, we considered that an LR of 10 or more would be clinically useful. All studies were poor quality. Infancy increased the risk of physical abuse or neglect in severely injured or admitted children (LRs 7.7-13.0, 2 studies) but was not strongly associated in children attending the ED (LR 1.5, 95% CI: 0.9, 2.8; one study). Repeat attendance did not substantially increase the risk of abuse or neglect and may be confounded by chronic disease and socio-economic status (LRs 0.8-3.9, 3 studies). One study showed no evidence that the type of injury substantially increased the risk of physical abuse or neglect in severely injured children. There was no evidence that any of the markers (infancy, type of injury, repeated attendance) were sufficiently accurate (i.e. LR >or= 10) to screen injured children in the ED to identify those requiring paediatric assessment for possible physical abuse or neglect. Clinicians should be aware that among injured children at ED a high proportion of abused children will present without these characteristics and a high proportion of non-abused children will present with them. Information about age, injury type and repeat attendances should be interpreted in this context.

Wagemans, Jan; Malambu, Edouard; Borms, Luc; Fiorito, Luca

2016-02-01

The BR1 research reactor at SCK•CEN has a spherical cavity in the graphite above the reactor core. In this cavity an accurately characterised Maxwellian thermal neutron field is present. Different converters can be loaded in the cavity in order to obtain other types of neutron (and gamma) irradiation fields. Inside the so-called MARK III converter a fast 235U(n,f) prompt fission neutron field can be obtained. With the support of MCNP calculations, irradiations in MARK III can be directly related to the pure 235U(n,f) prompt fission neutron spectrum. For this purpose MARK III spectrum averaged cross sections for the most relevant fluence dosimetry reactions have been determined. A calibration factor for absolute measurements has been determined applying activation dosimetry following ISO/IEC 17025 standards.

Otero, Valerie; Pollock, Steven; Finkelstein, Noah

2010-11-01

In response to substantial evidence that many U.S. students are inadequately prepared in science and mathematics, we have developed an effective and adaptable model that improves the education of all students in introductory physics and increases the numbers of talented physics majors becoming certified to teach physics. We report on the Colorado Learning Assistant model and discuss its effectiveness at a large research university. Since its inception in 2003, we have increased the pool of well-qualified K-12 physics teachers by a factor of approximately three, engaged scientists significantly in the recruiting and preparation of future teachers, and improved the introductory physics sequence so that students' learning gains are typically double the traditional average.

In this contribution we have tried to point out the way in which the financial management of SCK/CEN is carried out. Despite the fact that research is still very often considered to be an area of activity in which decisions can only be made on the basis of intuition we believe that methods based on the principle of management by objectives and follow-up of expenditure and results, has enabled us to make our managerial staff and personnel ''resource-minded''. However, it should be stressed that in most cases, and contrary to private industry, the output of most R and D work cannot be measured or balanced in terms of cost and income. Cost accounting therefore only provides information on the input, whereas the output has to be evaluated in terms of long-term benefits to the nation. As these are rather diffucult to quantify, no clear balance can be shown and discussions may often arises as to the real output and the necessity to carry out R and D work. (author)

This paper reports on the use of a Community-Engaged Research (CEnR) approach to develop a new research tool to involve members of the community in thinking about priorities for early child health and development in a deprived area of the UK. The CEnR approach involves researchers, professionals and members of the public working together during all stages of research and development.Researchers used a phased approach to the development of a Photo Grid tool including reviewing tools which could be used for community engagement, and testing the new tool based on feedback from workshops with local early years professionals and parents of young children.The Photo Grid tool is a flat square grid on which photo cards can be placed. Participants were asked to pace at the top of the grid the photos they considered most important for early child health and development, working down to the less important ones at the bottom. The findings showed that the resulting Photo Grid tool was a useful and successful method of engaging with the local community. The evidence for this is the high numbers of participants who completed a pilot study and who provided feedback on the method. By involving community members throughout the research process, it was possible to develop a method that would be acceptable to the local population, thus decreasing the likelihood of a lack of engagement. The success of the tool is therefore particularly encouraging as it engages "seldom heard voices," such as those with low literacy. The aim of this research was to consult with professionals and parents to develop a new research toolkit (Photo Grid), to understand community assets and priorities in relation to early child health and development in Blackpool, a socio-economic disadvantaged community. A Community-Engaged Research (CEnR) approach was used to consult with community members. This paper describes the process of using a CEnR approach in developing a Photo Grid toolkit.

2007-01-01

In 2006 research activity of the P-V Department was concentrated on the continuation of previous studies in the field of plasma physics and controlled nuclear fusion (CNF), but several new topics concerning plasma technology were also investigated. The main tasks of the research activities were as follows: 1. Studies of physical phenomena in pulsed discharges producing dense magnetized plasma; 2. Development of methods and tools for high-temperature plasma diagnostics; 3. Research in the field of plasma technologies. In a frame of the first task particular attention was paid to studies of X-ray pulses and fast electron beams emitted from different Plasma-Focus (PF) facilities. The correlation of X-ray pulses with pulsed electron beams and other corpuscular emissions (i.e. accelerated primary ions and fusion reaction products) was investigated in the PF-360 device in Swierk. The X-ray and corpuscular emission was also studied in a PF-1000 facility at IPPLM in Warsaw. Separate efforts were devoted to the investigation of fast electrons escaping from Tokamak-type facilities. Such studies were carried out in a frame of the EURATOM program, using special Cerenkov-type detectors within the CASTOR tokamak, operated at IPP in Prague. Signals from the Cerenkov detector were recorded and interpreted. Other studies concerned the design and construction of a new 4-channel Cerenkov detection system for a TORE-SUPRA facility at CEA-Cadarache. Since thermal loads upon the Cerenkov probe within the TORE SUPRA facility can amount to 1 MW/cm 2 , it was necessary to perform detailed computations of heat transfer in various materials (i.e. diamond-radiators and the probe body). Some efforts were devoted to the calibration of new nuclear track detectors (NTD) and their application for measurements of fusion-produced protons emitted from PF-360 and PF-1000 facilities. In frame of the EURATOM program the calibrated NTD were also applied for measurements of fusion-protons in a TEXTOR

' laboratory. Additional radiation shielding was constructed and the computer assisted system for dosimetric monitoring was installed. Three experimental set-ups for electron and photon beam diagnostics are in course of installation and running -at: 4-5 MeV, 10-15 MeV, and 20 MeV. The 20 MeV unit will also be used for generation and metrology of narrow photon beams applicable in stereotactic radiosurgery. Preliminary design works are advanced, oriented, undertaken on an important project - high-power electron accelerators for radiation technology (10 MeV, 20-50 kW). Financial support for this task is still pending. A substantial part of the Department's activity was oriented to an international collaboration with accelerator physics centres. Two works completed in 1997 were extended in 1998: microwave pulsed generator destined for short beam bunches diagnostics was installed and put in operation at INFN-Frascati; 27 pieces of polarized ''door-knob'' r.f. couplers for superconducting cavities in HERA ring were installed and put in operation. In the course of 1998 we got the message from DESY, that couplers are working well and brought desirable improvement in operation reliability. The new item of collaboration with DESY, is design, construction and r.f. measurements of a copper model of accelerating ''superstructure'' for TESLA collider. If successful, the use of niobium ''superstructure'' can shorten by about a few kilometres the length of the TESLA linear accelerator. First four 1 m sections of model structures were sent to DESY at the end of 1998. The next four are in preparation. Some results of work done in 1998 were presented at conferences in Caen, Stockholm and Cracow

Cerit, N.

2005-01-01

Bringing up the young people who are seen as the guaranty of the future depends on a better education. One of the best ways of forming a high in quality education is connected to developing the quality in teacher training. Most of the developed countries have been carrying on studies in order to develop teacher training. School experience classes are the ones which are planned for the candidate teachers to observe the school in learning and teaching period and to practice in classrooms. Beginning from candidate teachers first years at school, this class should be thought to be beneficial for identifying their future school atmosphere, and it should be run effectively. For this purpose, it has been identified what difficulties the physics undergraduate and physics (with no thesis) master students, who took part in School Experience classes at the practice schools of Konya at which faculty-school cooperation is applied, had during activities, and their success at overcoming these difficulties, and their ideas about the practice school and its teachers. The research was done by making a survey to the physics undergraduate and physics(with no thesis) master students in 2003 Spring semester. The results of the research were analyzed for both girls and boys separately. After analyzed, the results showed that the most striking activity which both the undergraduate physics and physics(with no thesis) master students had difficulty was group activities. Moreover, it showed that 90 percent of the two groups had the idea that school experience activities would be beneficial for being a good physics teacher. It has been also recognized that the physics undergraduate students had a more positive view than physics(with no thesis) master students on the matter of meeting lack of interest from practice teachers, and taking the same course from the same teacher

Full text: The teaching program of nuclear physics at Peking University started in 1955, in answer to the demand of China's nuclear program. In 1958, the Department of Atomic Energy was founded. The name of this department was changed to the Department of Technique Physics in 1961. Graduates in nuclear physics and technical physics had great contribution in China's nuclear program. The nuclear physics specialty from the Department of Technique Physics merged into the School of Physics in 2001. At present, nuclear physics is not any more a major for undergraduate students in the school of physics, but there are Master programs and Ph. D programs in nuclear physics, nuclear techniques and heavy ion physics. About 200 new students are admitted each year in the School of Physics at Peking University. About 20 graduates from the School of Physics work or continue to study in nuclear physics and related fields each year. (author)

Full text: The Department of Training and Consulting concentrates on the dissemination of knowledge on radiation phenomena: the origins, applications and health effects of ionizing radiation in particular. Its activity is open to the public. However, the main recipients are students of secondary schools and teachers. During about 12 years of such activity the number of visitors has exceeded 60 000 persons, while during last few years the average number of our visitors varies between 6 000 and 7 000 per year, which shows how much this kind of activity is needed. It should be noted that the term 'visitor' is not the most appropriate, because what the 'visitor' actually experiences in the Department is a series of lectures with demonstrations, visits to the MARIA reactor or regular experimenting in a specially designed Laboratory of Atomic and Nuclear Physics for schools, teachers and university students. The Department organized two permanent exhibitions. One is connected with the nuclear waste treatment and storage, another one displays a large model. 4x4x4 m. of a nuclear reactor of the WWER-type which was about to be installed at Zarnowiec about 20 years ago. The Department is equally active during annual Picnics and Festivals of Science in Warsaw and other Polish towns. Our staff is often asked to deliver lectures outside the Institute for Nuclear Studies, and participates in discussions on problems of teaching, in addition, the Department leads, together with the Institute of Physics of the Polish Academy of Sciences, Warsaw, the annual competition, named '' Physical Paths '', for high-school students. The competition is arranged in three categories: research, demonstration of physical phenomena, and essays on physics and its relation to civilization. This competition particularly stimulates small educational centers in Poland. This year, 2010, the competition was organized for the fifth time. The Department of Training and Consulting arranges regular courses

Since 1994, the U.S. Department of Energy (DOE) has provided cooperative assistance to the non-nuclear weapons states of the Former Soviet Union. This effort, within DOE's program of Material Protection, Control, and Accounting (MPC ampersand A), identified the Institute of Nuclear Physics (INP) in Uzbekistan and the Ignalina Nuclear Power Plant (INPP) in Lithuania as sites for cooperative MPC ampersand A projects. The INP, located just outside of Tashkent, is the site of a 10-megawatt WWR-SM research reactor. This reactor is expected to remain operational as a major nuclear research and isotope production reactor for Central Asia. The INPP, located 100 kilometers northeast of the capital city of Vilnius, consists of two Russian-made RBMK reactors with a combined power output of 3,000 megawatts (electric). This power plant has been the subject of international safety and security concerns, which prompted DOE's cooperative assistance effort. This paper describes U.S. progress in a multi-national effort directed at implementing physical protection upgrades in Lithuania and Uzbekistan. The upgrades agreed upon between DOE and the INP and between DOE and the INPP have been designed to interface with upgrades being implemented by other donor countries. DOE/INPP upgrade projects include providing training on U.S. approaches to physical protection, access control through the main vehicle portal, a hardened central alarm station, and improved guard force communications. DOE/INP upgrade projects in Uzbekistan include an access control system, a hardened fresh fuel storage vault, an interior intrusion detection and assessment system, and an integrated alarm display and assessment system

Lindner, L.

1977-01-01

In 1946, the Institute for Nuclear Physics Research (IKO) in Amsterdam was founded as a typical post World War II effort to cope with the surge in scientific research, primarily in the USA. At present, the Institute encompasses almost 250 workers - including a Philips research group - out of which nearly 30 are members of the Chemistry Department. In the beginning, the investigations dealt with more or less conventional tracerwork using long-lived radionuclides produced in nuclear reactors. This changed rapidly with the synchrocyclotron coming into operation in 1947. The present can be best characterized as a sort of a transition state. Emphasis has been laid upon more typical chemical aspects of the research program: a shift from ''nuclear'' chemistry to ''radio'' chemistry. The future is determined by the 500 MeV linear electron accelerator, dubbed MEA (Medium Energy Accelerator) already under construction. (T.G.)

2005-11-01

The latest IAEA Co-ordinated Research Project (CRP-8) focuses on the application of the Master Curve approach to monitor fracture toughness of reactor pressure vessels in nuclear power power plants. Three main work areas have been identified: (a) constraint and geometry effects on Master Curve To values; (b) loading rate effects up to impact conditions; (c) potential changes of Master Curve shape for highly embrittled materials. After the kick-off meeting in Vienna in October 2004, the first Research Coordination Meeting was held in May 2005, hosted by AEKI Budapest. The present document focuses on the participation and contribution of SCK-CEN to Topic Area no. 2 (Loading rate effects on Master Curve - Impact Loading), for which E. Lucon acts as co-task leader. A Round-Robin exercise is planned for early 2006, consisting in 10 tests per participant on precracked Charpy-V specimen of JRQ, tested dynamically using an instrumented pendulum; the results will be analysed using the Master Curve procedure (ASTM E1921-05) and compared to data obtained at other loading rates (quasi-static and/or dynamic). Guidelines and detailed specifications have been produced and circulated after the meeting in Budapest. SCK-CEN has also produced data reporting sheets in EXCEL97 form, which will be used for reporting all fracture toughness test results (at quasi-static, dynamic or impact loading rates) performed in the framework of the CRP-8.

As usual we have been visited by over 6400 visitors, mainly students from secondary schools in Poland. In the opinion of the teachers the outcome of all visits was very positive. In addition, special courses on radioactivity and nuclear energy dedicated to teachers were organized. Many lectures have been delivered outside of the Department, in schools, universities and institutes. The Department is constantly developing experiments that can be conducted by students of secondary schools and universities, as well as by professionals. At the moment there are about 28 experiments available for the guests of the Department. The list of experiments and their descriptions can be found on our home page http://dsid.ipj.gov.pl. They cover the measurement of lifetimes, essential elements of radioprotection, absorption of radiation in various materials, excitation of fluorescence radiation, influence of magnetic fields on beta radiation as well as on electrons emitted from a typical electron gun, Compton scattering and elements of gamma spectroscopy, the search for radioactive pollution, the basics of the wave-particle dualism of matter, and the recently added Frank-Hertz experiment and radioactive decay of thoron. For the fifth time the Department has organized (together with the Institute of Physics of the Polish Academy of Sciences, Warsaw) '' The Physical Pathways '' competition for students of secondary schools. The students could choose one of three possibilities (even all of them): either to submit a scientific paper, to present a demonstration of a physical phenomena, or to write an essay on the connection between physics and the development of civilization. They could also submit work prepared by a team of up to 3 persons. The level of the competition turned out to be very high. The competition apparently attracts more and

Full Text Available Education systems are being affected in parallel by newly emerging hardware and new developments    occurring in technology daily. Tablet usage especially is becoming ubiquitous in the teaching‐learning processes in recent years. Therefore, using the tablets effectively, managing them and having a high level of tablet literacy play an important role within the education system. This study aimed at determining the tablet literacy levels of students in the Physical Education and Sports Teaching department at Sakarya University in Turkey, and examining this data with regard to various variables. Some 276 students participated in the study. Findings of the study suggest that the sample has a high tablet literacy level. While no significant difference was found in the tablet literacy  by gender, the students in the 2nd grade are noted to have higher levels of tablet literacy compared to the students in 3rd and 4th grades and tablet owners are more tablet literate when compared to non‐owners. A significant but low level correlation was found between the tablet usage time and tablet literacy.

France has not prohibited all forms of corporal punishment, and the point at which an act is regarded as physical abuse is not clearly determined. The aim of our study was to compare perception of a caregiver's violent behavior toward his child by professionals and parents in an emergency department and determine characteristics associated with that perception. A cross-sectional study was conducted from November 2013 to October 2014 in the emergency department of the pediatric university hospital in Bordeaux, France. An anonymous self-administered questionnaire, including vignettes describing hypothetical situations of violent interaction between a parent and child, and items related to sociodemographic and family characteristics, was administered to professionals and parents. Vignettes included varying child's age and behavior, frequency of caregiver's behavior, hitting with/without an object, and targeted child's body part. Violent behavior was restricted to hitting for reasons of feasibility. Respondents were asked to rate the acceptability of situations on a 100-mm visual analog scale. Analyses were multivariate mixed Poisson regressions. A total of 1,001 participants assessed the vignettes. Participants were predominantly females (64%), married or living with a partner (87%), with a median age of 34 years. Professionals assessed vignettes as acceptable significantly more than parents (mean rating 2.8 times higher; p children were less tolerant. Such findings indicate the need for additional research to better appreciate consequences and severity of violent behavior toward children, and the need to educate parents and professionals.

TEACHING PHYSICS: Connecting with Advancing Physics

Science.gov (United States)

Brown, L. M.

2000-05-01

A case is made for the Institute of Physics to provide services to back up physics courses in the first foundation year in British universities. There are several reasons why it is timely to consider such action. Firstly there are several physics departments in the country which are scarcely large enough to maintain a full four-year honours course while at the same time winning a lucrative research reputation. Secondly, if Advancing Physics, the new A-level initiative sponsored by the Institute of Physics, is successful, there will be a flood of new recruits into the subject, just at a time when the number of places available in universities is static or, more likely, falling. Thirdly, the new students will expect very high standards of presentation, for both practical and theoretical work: standards which, given the resources available to existing departments, will be very hard to provide under the present circumstances. It is proposed that the Standing Committee of Physics Professors should examine whether and in what ways the provision of IOP services to universities might be made. The SCPP is an appropriate body to manage such a resource.

Ma and LLFP transmutation in MTPs and ADSs: the typical SCK.CEN case of transmutations in BR2 and Myrrha. Position with respect to the global needs

The proposed paper indicates the performances, in the domain of the transmutation of MAs and LLFPs, of the high flux materials testing reactor BR2 located at SCK-CEN, and compares them with those of the multipurpose ADS MYRRHA, the pre-design of which is at the present time being finalized at SCK-CEN. With thermal neutron fluxes reaching 9.10 14 n/cm 2 s in thermal positions and 4.10 14 n/cm 2 s in the reactor core and, in the latter position, a fast flux (E>0.1 MeV) of 7.10 14 n/cm 2 s, BR2 has a transmutation throughput of the order of 1.5 kg Np+Am per 200 EFPD. This capacity can be used for investigating at the technological scale the transmutation of MAs and LLFPs in a thermal neutron spectrum with a high contribution of epithermal and fast neutrons. The metallurgical behaviour of the targets can hence be studied. In MYRRHA, higher fast fluxes are expected to be attained in irradiation positions near the spallation source, viz fast fluxes (E>0.75 MeV) up to 10. 15 n/cm 2 s. One of the purposes of MYRRHA is therefore its utilisation for the investigation of actinide transmutation feasibility with ADSs. (author)

Full text: The Department of Training and Consulting regularly serves secondary schools pupils and teachers, university students and the public. Almost 6600 visitors, mainly students from secondary schools in Poland, visited the Department. In addition to regular lectures, demonstrations, visits to the reactor MARIA and two current exhibitions (on nuclear waste and the WWER reactor model), several laboratory experiments have been organized for secondary schools. A one-day summer workshop on '' Basics of nuclear radiation, its properties and use in science, technology and medicine '' offered secondary school teachers a general understanding of the problems connected with radioactivity. The Department is constantly developing experiments that can be conducted by students of secondary schools and universities, as well as by professionals. At the moment, there are about 25 experiments available for the guests of the Department. They cover the measurement of lifetimes, essential elements of radioprotection, absorption of radiation in various materials, excitation of fluorescence radiation, influence of magnetic fields on beta radiation as well as on electrons emitted from a typical electron gun, Compton scattering and elements of gamma spectroscopy, search for radioactive pollutions etc. Three experiments were modernized to enable them to be conducted over the Internet. This project is a bit delayed but should be finished by the end of April 2009. For the third time the Department organized (together with the Institute of Physics of the Polish Academy of Sciences, Warsaw) '' The Physical Pathways '' competition for secondary school students. The students could choose one of three possibilities (even all of them): either to submit a scientific paper, to present a demonstration of a physical phenomenon, or to write an essay on the connection between physics and the development of civilization. They could also submit work prepared by a team of up to three persons. The

Assessment of the pelagic fish populations using CEN multi-mesh gillnets: consequences for the characterization of the fish communities

Directory of Open Access Journals (Sweden)

2008-01-01

Full Text Available The contribution of CEN standard pelagic nets to the assessment of fish communities is tested by comparing three metrics (species composition, species abundance, and size structures measured in accordance with the standard (i.e. using benthic nets only to those calculated from the total effort (i.e. including pelagic nets. Hydroacoustic surveys were used simultaneously to assess fish densities in the pelagic habitat. The results show that in most cases the pelagic nets did not provide any extra information about these three metrics. However, their inclusion in the calculation of CPUE and size structures may affect the picture of the fish communities, especially in lakes containing salmonid populations. This study highlights the need to sample pelagic fish when assessing fish communities in order to determine lake quality.

This report describes early health physics activities from September 30 to October 1 taken by the authors' department after the JCO accident. They firstly knew the accident at around 12:20 (about 2 hr after the criticality). The activities involved the planning of schedule for ending the criticality; calculation of scheduled dose for the work to end it; dose measurement around JCO site; loaning out of devices for measuring neutron and of personal dose-meter; collection and radioactivity measurement of dust and soil, and of drinking water; and examination for contamination of people around the site, of their houses inside and of school gardens and equipments. The dose was scheduled to be firstly 20 mSv and then changed to 50 mSv due to the actual measurement at the accident site. The working time was to be 3 min at the site. The work was on either the dose or time. Radiation monitoring outside the JCO site revealed the presence of Na-24 and Cs-138: neutron dose was 10 times as high as γ-ray dose. The time course of dose rate change was found to be in parallel with the progress of works to end the criticality. (K.H.)

Full Text Available Time spent using various technological equipment increases every day with rapid technology development. Unfortunately, technology addiction is becoming an important issue. Especially with the development and ubiquity of mobile technologies, social media addiction is expanding. The aim of this study is to measure the Facebook addiction levels of 274 students at the Physical Education and Sports Teaching Department in a public university in Turkey and to examine their Facebook addiction levels against a number of variables. Descriptive method was used within the framework of the study and the “Facebook Addiction Survey” developed by Çam and İşbulan (2012 was used as the data collection instrument. The results of the study show the students had low levels of Facebook addiction. On the other hand, when the Facebook addiction level mean scores were compared, male students were seen to have higher scores than female students. Students in the 3rd grade had higher mean scores than those in the 1st and 2nd grades. Although Facebook addiction is not a problem among the students, proactive action is needed to enhance student awareness of the problem and ensure future teachers can be role models in an addiction‐free academic environment.

The principal activities in the fields of solid-state physics (neutron scattering), plasma physics, nuclear spectroscopy and meteorology are presented. The main experimental and theoretical work in solid-state physics has involved: investigation of the static and dynamic properties of magnetic solids; studies of various kinds of phase transitions in solids and liquid-like systems; electronic energy band calculations of metals; and investigations of the structure and lattice dynamics of molecular crystals and adsorbed monolayers. The work of the plasma physics section is centered on technology of interest for future fusion reactors and on basic plasma physics. The technological aspects of plasma phsics are undertaken with one of the possible refuelling schemes for fusion reactors in mind. The main object of the basic research is investigations of waves and instabilites in a relatively cold steady state plasma. The activites in the field of nuclear spectroscopy have concerned an attempt to form the 236 U fission isomer with thermal neutrons and studies of the fine structure in the mass distribution for fission fragments. The meteorology section is primarily engaged in studies of the planetary boundary layer. (B.R.H.)

Full text: The activity of department P-10 is focused on the development of new acceleration techniques and technology, as well as on applications of particle accelerators. In 2008, the following topics were investigated and/or realized: 1. A linear accelerator for protons called TOP (Terapia Oncologica con Protoni, Oncological Proton Therapy). Basically a proton linac of modified Alvarez type working at 3000 MHz frequency and delivering beams in the energy range from 65 MeV to 200 MeV. In 2005, a contract was signed between ENEA and SINS-Swierk for the design, manufacture and delivery to Frascati of the input section of a 65 MeV linac. This section of SCDTL type will increase the proton energy from 7 to 16 MeV. In 2008, the field distribution in the manufactured structure was measured and optimized using available universal test stand. Measurements were also performed in ENEA/Frascati in October; a small difference in results, around 0.25%, is under investigation. Beam dynamics calculations using 3D codes have been started in parallel. 2. Preparation for participation in the international X-FEL project. Calculations of the parasitic Higher Order Modes (HOMs) induced in superconducting accelerating structures by very short electron bunches have been continued. Thanks to the special research grant received by department P-10 the design and completion of the HOM elements has been started for two accelerating modules, where each module consists of eight superconducting accelerating structures and focusing/correcting elements. 3. Superconducting layers; studies in INFN-Roma. Within the European CARE/JRA1/WP4-2 project, serious modification of the Nb-coating stand for the 1.3 GHz single-cell copper resonators using a vacuum arc was performed. Thanks to this stand the internal surface of the resonator was successfully coated. 4. TiN coating vacuum stand for RF components. At this stand the analysis of the TiN layer thickness as a function of reactive atmosphere pressure

Full text: The Department of Training and Consulting is regularly serving secondary school pupils and teachers, university students and the public. As usual we have been visited by more than 5000 visitors, mainly students from secondary schools. Since January 2003, the Department participated in an European program called NUPEX (from Nuclear Physics Experience) that aimed at creating an internet platform of educational material from nuclear physics and its applications. The platform was finally prepared in eight languages (English, French, German, Italian, Flemish, Greek, Hungarian and Polish) and is dedicated to pupils from secondary schools and to science teachers. The whole material can be found at http://www.nupex.org. The Polish part is displayed additionally at http://ipj.gov.pl/pl/szkolenia/nupex. It is worth mentioning that the Polish group played an important role in the whole project. Seven modules were fully prepared by us; we also were active in helping the other Project's participants to understand technicalities connected with preparation of the material for internet. New educational posters have been designed by the Department. The titles of these posters are: Energy and its transformations; typical electric power plants; Nuclear Power Plants; Nuclear Power Plants in Europe and in the World. The posters are offered to visiting schools. The number of possible experiments at our Laboratory of Atomic Physics is still increasing. Recently a computer simulation of the process of start-up of the nuclear reactor was prepared. Although it can be considered as a game, in fact the animation reflects the reality of the process and can be used for training of nuclear reactor's operators. For the first time one, of the leading secondary schools in Warsaw, the Stefan Batory School, participated in a Summer School of Physics organized at our Department, which lasted 10 days. Most of the educational program was filled with the basics of nuclear physics with emphasis

Full text: We deal with environmental physics and the radiation transport physics, both theoretically and experimentally. Some results find their way to practical applications. Our environmental physics research encompasses hydrogeological problems as well as measurements of trace elements in the atmosphere and in the water. Theoretical (analytical and numerical) and experimental issues of the radiation transport and radiation fields are our main field of research. The interest in radiation transport phenomena is stimulated by their importance for the environmental physics, industrial and nuclear facilities and methods of geophysical. Environmental isotopes and noble gases are used in the investigation of water-bearing geological formations in order to determine the origin and age of groundwater. The papers listed below and three ''Reports on research'' present recent achievements in this field. The gas chromatography methods are used for monitoring the anthropogenic trace gases (SF 6 and freons), which participate in the Earth green-house effect. A very high detection level of SF 6 in water, 0.0028 fg/cm 3 H 2 0, has been reached as required for hydrogeological purposes. A preliminary verification of the SF 6 tracer method for dating young groundwaters by the tritium method has been carried out. We carried on the work on a method of radon measurement in soil in connection with geological conditions. The national seminar ''Radon in Environment'' organized at the INP aroused an interest of Polish scientific centres in that field. The seminar gathered 60 participants who presented 24 oral reports and 8 posters. Within the scope of the radiation transport physics we studied thermal neutron transport in finite hydrogenous media. Advantages and limitations of a Monte Carlo code (MCNP) in thermal neutron transport simulations have been examined by both the analytical solution and the experiment on the INP pulsed neutron generator.

Full text: The scope of scientific work of the Department is best characterized as Physics of the Earth. Our studies comprise the physics of the atmosphere, problems of groundwater systems, of outflows of gases (radon and thoron) from tectonic faults and caverns. We are studying the heterogeneity of rock formations and also working on problems of the nuclear geophysics. In the greater part of this research methods of nuclear physics are employed - neutrons as probing particles or radioactive and stable isotopes in tracer technologies. Concentrations of F-11, F-113 and CHCl 3 , CHCCl 3 , CCl 4 , F-12 and SF 6 in Cracow atmosphere were measured by gas chromatography (GS). The five-point interpolation-procedure for calculations of week weight-averaged concentrations of the above-mentioned gases was developed. At the Kasprowy Wierch Station (Tatra Mts.) the measurement of greenhouse effect gases (CH 4 , CO 2 and SF 6 ) has been continued. A method for measuring the SF 6 concentration in water as a hydrologic tracer was developed for determining the ages of young groundwater systems. Similar enrichment is being developed for such potential tracers as freon F-11 and F-12. Studies were continued on models for the interpretation of tracer data and transit time calculations in groundwater systems. Environmental tracer study of the Oligocene aquifer in the Mazovian basin has been completed. It has appeared that in the Late Glacial the recharge of groundwater systems in the Mazovian basin was, to a high degree, from paleolakes. Moderate concentrations of 4 He excess showed that the glacial waters cannot be older than those recharged at the end stages of the Last Glacial. The heterogeneity of a rock medium as: variable density, occurrence of concretions of high neutron absorbers etc. have been studied. The influence of the granulation change on the neutron absorption has been examined. A study of effective neutron parameters of an heterogeneous material containing highly

The Panel recommends the following major roles and missions for the laboratories: perform the Department's national trust fundamental research missions in the physical sciences, including high energy and nuclear physics, and the radiobiological sciences including nuclear medicine; sustain scientific staff core capabilities and specialized research facilities for laboratory research purposes and for use by other Federal agencies and the private sector; perform independent scientific and technical assessment or verification studies required by the Department; and perform generic research and development where it is judged to be in the public interest or where for economic or technical reasons industry does not choose to support it. Organizational efficiencies if implemented by the Department could contribute toward optimal performance of the laboratories. The Panel recommends that a high level official, such as a Deputy Under Secretary, be appointed to serve as Chief Laboratory Executive with authority to help determine and defend the research and development budget, to allocate resources, to decide where work is to be done, and to assess periodically laboratory performance. Laboratory directors should be given substantially more flexibility to deploy resources and to initiate or adapt programs within broad guidelines provided by the Department. The panel recommends the following actions to increase the usefulness of the laboratories and to promote technology transfer to the private sector: establish user groups for all major mission programs and facilities to ensure greater relevance for Department and laboratory efforts; allow the laboratories to do more reimbursable work for others (other Federal agencies, state and local governments, and industry) by relaxing constraints on such work; implement vigorously the recently liberalized patent policy; permit and encourage joint ventures with industry

The Science Faculty of the Comenius University in Bratislava established the nuclear physics specialization in 1962. Students enrolled in the study course acquired basic knowledge in mathematics and physics, foundations of the microstructure of matter and experimental methods of nuclear physics and technics. Since 1976 nuclear physics has been a separate study field which from the fourth year of study has its narrow specializations, namely applied nuclear physics, experimental nuclear physics and physics of the atomic nucleus and elementary particles. A change has recently been made in the system of optional lectures with the aim of providing the students with a wider range of knowledge in the physics of nuclear reactors and the use of computer technology and microelectronics in nuclear physics and technology. In 1980 a postgraduate study course was opened oriented to nuclear power and the environment. (E.S.)

In this contest, it is worth to mention the organization of the two 3-days Workshops '' On the nuclear energy from the very basics '', aimed to offer the teachers of secondary schools general understanding of the problems connected with nuclear energy. The Workshops were organized in collaboration with the International Atomic Energy Agency and Polish Atomic Agency. Also two other one-day courses on the nuclear radiation were organized for teachers from rather remote parts of Poland. In the teachers' opinion all these events were very successful. The Department is constantly developing experiments that can be conducted by students of secondary schools and universities, as well as by professionals. At the moment there are about 20 experiments available for the guests of the Department. They cover the measurements of lifetimes, essential elements of radioprotection, absorption of radiation in various materials, excitation of fluorescence radiation, influence of magnetic field on beta radiation as well as on electrons emitted from a typical electron gun, Compton scattering and elements of gamma spectroscopy, search for radioactive pollutions etc. A new task of preparing some experiments to be driven through the internet was put forward. It is hoped that this project will end within 2008. For the second time the Department has organized (together with the Institute of Physics of the Polish Academy of Sciences, Warsaw) '' The Physical Pathways '' competition for the students of secondary schools.

The principal activities in the fields of solid-state physics (neutron scattering), plasma physics and meteorology are presented in this report that covers the period 1 January to 31 December 1976. In addition, research on nuclear spectroscopy was carried out up until March 31, 1976. The experimental and theoretical work in solid-state physics is roughly divided into the following main subject fields: investigations of the dynamic and static properties of magnetic and superconducting solids; studies of various kinds of phase transitions in magnetic and molecular systems; and investigations of the dynamic and static properties of molecular crystals and adsorbed monolayers. The main object of basic research in plasma physics is to investigate waves and instabilities in a relatively cold steady state plasma (produced in a Q-machine). Turbulence, ion cyclotron waves, and ion-acoustic waves in the presence of electron plasma waves are the chief phenomena investigated. Work on nuclear spectroscopy was concentrated on problems relating to fission. The meteorology section is primarily engaged in studies of the planetary boundary layer. (B.R.H.)

This paper documents the history of photovoltaic use within the Department of Defense leading up to the installation of 2.1 MW of photovoltaics underway today. This history describes the evolution of the Department of Defense's Tri-Service Photovoltaic Review Committee and the committee's strategic plan to realize photovoltaic's full potential through outreach, conditioning of the federal procurement system, and specific project development. The Photovoltaic Review Committee estimates photovoltaic's potential at nearly 4,000 MW, of which about 700 MW are considered to be cost-effective at today's prices. The paper describes photovoltaic's potential within the Department of Defense, the status and features of the 2.1-MW worth of photovoltaic systems under installation, and how these systems are selected and implemented. The paper also documents support provided to the Department of Defense by the Department of Energy dating back to the late 70s. copyright 1997 American Institute of Physics

Jurkiewicz were participating in this project; -ATLAS project at LHC (CERN) - one physicist: K. Piotrzkowski from the department was participating in this project. 11 physicists and 8 engineers and technicians have been involved in carrying above programs. ZEUS experiment is the continuation of the investigation of e ± p interactions at HERA collider which has started over 10 years ago and has a perspective of another 5 years of activity. The upgrade of HERA and the expected 5-7 fold increase of luminosity makes the physics program very attractive. Cracow group is responsible for upgrade of the luminosity monitor to meet the new working conditions after HERA upgrade. An extended proposal for luminosity measurement after HERA upgrade, including the measurements of the Bremsstrahlung events rates by additional detectors apart from the photon calorimeter (i.e. 6m and 40m electron taggers and luminosity spectrometer), has been prepared and was accepted for realization by the ZEUS collaboration and the DESY Physics Research Committee (PRC).

The objective of this study was to examine the experiences of violent incidents by nurses in Indonesian emergency departments. The World Health Organization's structured questionnaire on workplace violence in the health sector was modified and translated into Bahasa. The study participants were 169 nurses working in emergency departments in six hospitals in Jakarta and Bekasi, Indonesia. The gathered data were analyzed using descriptive and multivariate logistic regression. Ten percent of emergency nurses reported experiencing physical violence, perpetrated mostly by patients, whereas more than half of emergency nurses (54.6%) reported experiencing non-physical violence, with patients' relative as the main perpetrators. A majority of nurses (55.6%) did not have encouragement to report workplace violence, and very few nurses (10.1%) had received any information or training about workplace violence. The findings of this study highlighted the seriousness of violence in Indonesian emergency departments. Support from management, encouragement to report violence, and access to workplace violence training were expected to mitigate and manage violence against nurses in emergency departments.

Nowicki, L.

2006-01-01

In 2005 the Department held a steady course. Topics of nuclear physics, atomic physics and materials research that started in previous years were continued. Although our team was smaller than years ago, the scientific activity, estimated by number of published papers is still very high. Scientists of the Department are co-authors or authors of more than 50 papers. Nuclear physics, which is our main-stream activity, covered a wide energy range. It started close to the Coulomb barrier, where 6 He breakup on heavy nuclei were studied, and ended at zones of tens of GeV; such high energies were used to investigate spin structure of deuterons and to explore hadron leptoproduction. Traditionally, experimental investigations in the fields of atomic physics and of physics of materials completed the scene. Our old Van de Graaff accelerator Lech was used for studies of M-shell ionisation of heavy elements, for hardening of Ultra-High Molecular Weight Polyethylene and for characterisation of materials with RBS and NRA techniques. The VdG runs perfectly although it is over 40 years old. Two Ph.D. students finished their theses and were promoted. Izabela Fijal's work concerned multi-ionization and intrashell coupling effects for L-shell x-ray emission induced by heavy ions, while Sergiy Mezhevych showed studies on scattering of 11 B from carbon isotopes. It is obvious that contemporary works on physics do not arise in a single lab. Our contributions to many papers were possible due owing to collaborations involving many institutions. Some of them are listed: GSI, Darmstadt (PANDA Collaboration) DESY, Hamburg (HERMES Collaboration) Institut fuer Kernphysik, Forschungszentrum Juelich Forschungszentrum Rossendorf CSNSM, Orsay GANIL, Caen University of Huelva Institute of Nuclear Research, Kiev SLCJ, Warsaw ITME, Warsaw Some of our colleagues traditionally gave lectures and made physical demonstrations on Warsaw informal learning events: 9 th Science Picnic and 9 th Science Festival

Full text: The department of Training and Consulting is regularly serving secondary schools' pupils and teachers, university students and the public. The year 2003 set up a new record: the Department accepted a bout 7000 visitors, about 2000 more than during 2002. A truly great event was the opening of the permanent exhibition displaying the model of nuclear power plant originally planned to be built in Zarnowiec near Gdansk. The opening was combined with a short symposium on the ''Nuclear Physics and Technology - Today and Tomorrow's Social Education in European Union''. The opening was visited by many prominent guests from Polish Atomic Agency, local governments, universities and institutes. In addition, the Department participated in the organization of a symposium dedicated to the 100 th Anniversary of the first Nobel Prize awarded to Marie Curie-Sklodowska. This was also an occasion for a small exhibition based on photographs and exhibits borrowed from the Maria Curie-Sklodowska Museum in Warsaw, which was co-organiser of the symposium. The main organizer and proposer of the symposium was a social organization, the Interschool Committee of Promotion of the Educational Undertakings ''Europe 2000'', which promotes educational initiatives for the youth from Otwock, a town near to Swierk. It was our pleasure that our Department was chosen as the place for the organization of this symposium in which the best pupils, local authorities from Otwock, and sponsors of the activity of the aforementioned group were present. On the 15 th of October we celebrated the 5 th anniversary of our educational activity that started with the opening of the exhibition on ''Nuclear wastes: problems, solutions''. The exhibition is still displayed and attracts attention. It is a real pleasure to see how much the interest in our activity has grown through all those years. On the other hand, the educational efforts of the Department turned out to be worth our labor: in the all

The studies at CEN-SCK related to the R and D of geological disposal are performed within the research unit `waste and disposal` which also deals with the characterization of waste packages and their compatibility with host clay. The in situ test program developed by the underground research facility is shown. The in situ corrosion and leaching test, the combined radiation/heating test CERBERUS, the in situ migration experiment and the geotechnical survey on the gallery structures and their surrounding clay have been continued, and the main achievements until mid 1993 are reported. New actions have been started since 1991 related to hydrogeological modeling, the migration of gas in clay and the `PARCLAY` demonstration test. Besides the periodic measurement of water level in hydrological observation well network, the critical review of the previous regional hydrological modeling has been carried out. Migration studies were extended to the permeation of hydrogen, and the MEGAS project of the modeling and experiment of gas migration was started. Four main experiments, ARCHIMEDES, PHEBUS, BACCHUS 2 and ATLAS, as the international efforts are explained. (K.I.).

Verbal abuse and physical assault in the emergency department: Rates of violence, perceptions of safety, and attitudes towards security.

Science.gov (United States)

Partridge, Bradley; Affleck, Julia

2017-08-01

Emergency Department (ED) workers are prone to occupational violence, however the extent and impact of this may not be evenly felt across all roles in the ED. Explore: 1) the rate of verbal abuse and physical assaults experienced by ED staff, 2) perceptions of safety, 3) attitudes towards security officers, and 4) formal reporting of incidents. 330 ED workers were surveyed at four public hospitals in one metropolitan health service district in Queensland, Australia, including 179 nurses, 83 medical staff, 44 administration staff, 14 allied health, and 9 operational. Nurses were more likely to have been physically assaulted in the last six months and were less likely to feel safe. Most ED staff across all roles experienced verbal abuse. Nurses were better than medical staff at reporting instances of occupational violence although overall reporting across all roles was low. Staff who thought that security officers respond to incidents quickly and are a visible presence in the ED were more likely to feel safe in the ED. Workers in the ED, particularly nurses, experience high rates of verbal abuse and physical aggression and there may be a case for having designated security guards in the ED.

Full text: Our Department evolved from the Laboratory of Electronic Particle Detectors (originally called the Laboratory of Filmless Detectors) founded in 1972. The department is involved in three running experiments (DELPHI at CERN, H1 at DESY and BELLE at KEK). In 1999, we joined the LHC-b experiment at CERN. In addition, three department members work part-time for the ATLAS collaboration at CERN and our technicians have been working for several years on the construction and testing of superconducting cavities for the TESLA project. This arrangement provides a neat equilibrium between data producing experiments (2000 is the last year of the DELPHI running) and future projects. The main results of work done in 1999 are covered in reports on research. Here we mention only a few highlights. The first runs of the BELLE experiment have shown that the apparatus and the software can cope with the luminosity of 6 x 10 31 cm -2 s -1 presently available at KEK-B. The DELPHI experiment measured the parameters of the W boson with an accuracy comparable to that of the Tevatron. This allowed still more precise tests of the Standard Model. Some of them, like the determination of the cross sections for the production of Z 0 Z 0 and q(anti)q pairs, were actually done in Cracow. A novel study of p-p and Λ-Λ correlations performed in Cracow showed that the size of the particle emitting region decreases with particle mass. The H1 experiment published the first results on open beauty production at HERA. The cross section seems to be higher than the predictions of Quantum Chromodynamics in the Next-to-Leading Order. The work on a prototype detector for the LHC-b has just started in Cracow. One should also mention high-quality carbon-carbon composites designed and produced in collaboration with the High Energy Physics Detector Construction Group. For the first time, there were as many as 47 papers (fulfilling the highest KBN standard) published in a single year, the members of our

In the August 1993 Health Physics Society (HPS) newsletter, the HPS Scientific and Public Issues Committee published a Position Statement entitled {open_quotes}Radiation Protection of the Public and the Environment.{close_quotes}. In this article, this HPS committee made the statement that they were deeply concerned by the trend for agencies to incorporate the ALARA concept as a regulatory requirements, without providing specific guidance as to what it means and how to implement it consistently. The HPS position paper was in response to the DOE notice on proposed rulemaking for Title 10 Code of Federal Regulations Part 834, {open_quotes}Radiation Protection of the Public and the Environment{close_quotes} (10 CFR 834). In the notice of proposed rulemaking for 10 CFR 834, the Department of Energy (DOE) defined ALARA as follows: {open_quotes}As used in this part, ALARA is not a dose limit, but rather a process which has the objective of attaining doses as far below the applicable limit of this part as is reasonably achievable{close_quotes} (10 CFR 834.2, p. 16283 of the Federal Register). The HPS position paper continues, {open_quotes}The section goes on to elaborate on what is meant by a process without providing sufficient guidance to assure uniform applicability of the process.{close_quotes}. Although this concern is directed towards the ALARA process as it relates to the environment, the Office of Health, which is responsible for occupational workers, shares the same definition for ALARA.

Research at the Department of Nuclear Radiospectroscopy of thr H. Niewodniczanski Institute of Nuclear Physics covers three areas: magnetic resonance, magnetic resonance imaging and solid state physics by computer simulation. In first of the mentioned above research directions, we apply magnetic resonance method in studies of molecular rotation in solids. Two ways of rotation have been distinguished: tunneling through the potential barriers and random jumps between distinct orientations. In the second one, the magnetic resonance microscope based on a 6.3 T superconducting magnet was completed. Each part of this system was tested and appropriate software has been written in the Laboratory and used for testing, optimization and running the experiment. In the field of solid state physics the work was concentrated around consequences of tetragonal-orthorhombic phase transition, experimentally observed in high temperature superconducting materials. In this section of the Annual Report, the detail descriptions of mentioned activities as well as the information about personnel employed in the Department, papers and reports published in 1994, contribution to conferences and grants are also given.

Full text: The principal Department's duties in 1999 have not changed and were consequently directed on development in the area of electron and ion accelerators and their applications in science, medicine and technology. Two important events dominated the current and future orientation of R and D activity. The first was finalizing of long time efforts for preparing of the ordered research project granted by the State Committee of Scientific Research and devoted to elaboration and design of a new electron accelerator for radiotherapy, with two energies of X-ray photon beams. This project was formally approved in March 1999 and due to organisatory procedures set in operation after few months. In the second half of 1999, an important progress was done in advancing the project. The second mentioned event is foundation by the government of a Multiyear Research Programme - called ''Isotopes and Accelerators''. This programme formulates a broad spectrum of important tasks oriented on application of isotopes and accelerator techniques in many branches of science and national economy. The expected participation of the Department in this programme comprises following subjects: medical interoperative accelerator, high power electron accelerator for radiation technology, and upgrading of cyclotron for isotopes production. In course of 1999, preparatory studies in these subjects were carried out. Some of the results were presented on conferences and seminars. An interesting experience was the expertise done on technical status of Eindhoven isochronous cyclotron and its possible transfer to Swierk as a professional tool for isotopes production. In the group of medical applications, three subjects were continued during 1999 and brought important results: - completion of microwave measurements of high gradient acceleration structure for low energy accelerators; such structure will be very useful solution for Co-Line and interoperative accelerator; - evaluation of design data and

The main activity of the Department is centered on the education of pupils, students and social groups interested in ionizing radiation. The number of visitors to our Department is steadily growing. Whereas in the year 2000 we were visited by about 2100 students from various secondary schools, this number more than doubled in 2001, when it passed 5200. One day was dedicated to a meeting with a group of science teachers-methodologists. A collaboration with the National Center for Supporting Vocational Education, Warsaw, has started and will hopefully bring interesting results. In addition, the Department organized professional courses on radiation protection for employees (accelerator operators and management personnel) of the Institute. An important innovation in our activity is the opening of the Laboratory of Atomic and Nuclear Physics dedicated mainly to high-schools. However, the equipment gathered in the laboratory permits one to conduct experiments on the level of the university students lab. First groups of both, secondary school pupils as well as students of physics, have already worked in our laboratory. The Department also arranged one month training for pupils from one of the technical schools of environmental protection in Konstancin near Warsaw. In addition to the experimental setups already in the Laboratory, a solid-state AMPTEK detector was put into operation in conjunction with X-ray scattering facility. Because of this innovation, one can now study not only the production of X-rays, their wave properties and transmission through various materials, but also observe Compton scattering, thus seeing the dual nature of X-rays. Because a new set-up which shows diffraction of electrons was also put into operation, one can additionally learn about the wave-particle duality for the case of massive particles. Scientific activity was quite varied which is illustrated by the titles of papers published. However, one should stress that the main experiments were

Department of Particle Theory - Overview

Full text: Research performed at the Department of Particle Theory is devoted to fundamental particles and their interactions. These studies are closely related to the current and future high energy experiments at e + e - and hadron-hadron colliders: LEP, TESLA, Tevatron and LHC. The papers reported below cover a wide range of particle physics from neutrino masses and oscillations to processes involving heavy particles like gauge and Higgs bosons or the top quark. An evidence of neutrino oscillations observed by the SuperKamiokande Collaboration was the most spectacular discovery of the year 1998. In a theoretical investigation performed at our department a relation has been found between the so called see-saw mechanism and the bi-maximal neutrino mixing. Since many years a very important and labour-consuming part of the research activities is related to precision tests of the Standard Model. In the last year successful runs of LEP2 stimulated an impressive progress in theoretical description of processes with two- and four-fermion final states in electron-positron annihilation. It is worth stressing that the results of the calculations have been distributed in the form of the computer programs (Monte Carlo and other types) which serve as an indispensable tool in the analysis of the experimental data. Although the whole scientific program is a natural continuation of the activities started earlier a few results obtained in the last year should be mentioned: Publication of the four-fermion Monte Carlo program KORALW for high energy e + e - colliders; Development of the exponentiation scheme at the spin amplitude level and studies of the anomalous couplings for the e + e - → f (anti)f (nγ) processes; Relation between QCD static potentials in momentum and position spaces, and its consequences for bottom and top quark pair production and spectroscopy; Participation in the preparation of the physics program of the pp experiments on LHC collider particularly for Higgs

Psicologia e Democracia em um Cenário de Cidade como Campo em Disputa

Elisa Martins

Full Text Available Resumo: No Rio de Janeiro, o planejamento urbano e o direito à cidade vêm sofrendo contundentes interferências do modelo neoliberal, colocando em conflito os interesses de quem habita o território e os das grandes corporações do capital financeiro. Tais interferências agravam problemas já conhecidos dos cariocas, como negação de direitos básicos, criminalização da pobreza e aumento do custo de vida. No presente texto, trabalhou-se com a ideia de cidade não como palco de uma disputa sócio-histórica de classes ou como objeto dessa disputa, mas como o emergir da própria disputa. Interessa-nos analisar e discutir os efeitos desse confronto, além de elaborar formas de resistência e de superação das desigualdades que marcam a experiência humana na realidade social brasileira. Nesse cenário, faz-se necessária a construção de outro modo de fazer Psicologia, comprometido em reunir elementos de ação capazes de intervir na realidade que vem sendo imposta a partir da perspectiva de cidade-negócio. Uma Psicologia que tenha a luta e participação política como metas para uma experiência democrática de sociedade, consolidando dessa forma o compromisso social como norteador da profissão.

Enabling department-scale supercomputing

Energy Technology Data Exchange (ETDEWEB)

Greenberg, D.S.; Hart, W.E.; Phillips, C.A.

1997-11-01

The Department of Energy (DOE) national laboratories have one of the longest and most consistent histories of supercomputer use. The authors summarize the architecture of DOE`s new supercomputers that are being built for the Accelerated Strategic Computing Initiative (ASCI). The authors then argue that in the near future scaled-down versions of these supercomputers with petaflop-per-weekend capabilities could become widely available to hundreds of research and engineering departments. The availability of such computational resources will allow simulation of physical phenomena to become a full-fledged third branch of scientific exploration, along with theory and experimentation. They describe the ASCI and other supercomputer applications at Sandia National Laboratories, and discuss which lessons learned from Sandia`s long history of supercomputing can be applied in this new setting.

Diagnostic accuracy of history, physical examination, and bedside ultrasound for diagnosis of extremity fractures in the emergency department: a systematic review.

Joshi, Nikita; Lira, Alena; Mehta, Ninfa; Paladino, Lorenzo; Sinert, Richard

2013-01-01

Understanding history, physical examination, and ultrasonography (US) to diagnose extremity fractures compared with radiography has potential benefits of decreasing radiation exposure, costs, and pain and improving emergency department (ED) resource management and triage time. The authors performed two electronic searches using PubMed and EMBASE databases for studies published between 1965 to 2012 using a strategy based on the inclusion of any patient presenting with extremity injuries suspicious for fracture who had history and physical examination and a separate search for US performed by an emergency physician (EP) with subsequent radiography. The primary outcome was operating characteristics of ED history, physical examination, and US in diagnosing radiologically proven extremity fractures. The methodologic quality of the studies was assessed using the quality assessment of studies of diagnostic accuracy tool (QUADAS-2). Nine studies met the inclusion criteria for history and physical examination, while eight studies met the inclusion criteria for US. There was significant heterogeneity in the studies that prevented data pooling. Data were organized into subgroups based on anatomic fracture locations, but heterogeneity within the subgroups also prevented data pooling. The prevalence of fracture varied among the studies from 22% to 70%. Upper extremity physical examination tests have positive likelihood ratios (LRs) ranging from 1.2 to infinity and negative LRs ranging from 0 to 0.8. US sensitivities varied between 85% and 100%, specificities varied between 73% and 100%, positive LRs varied between 3.2 and 56.1, and negative LRs varied between 0 and 0.2. Compared with radiography, EP US is an accurate diagnostic test to rule in or rule out extremity fractures. The diagnostic accuracy for history and physical examination are inconclusive. Future research is needed to understand the accuracy of ED US when combined with history and physical examination for upper

(full text) In the context of general discussions concerning the activity of the Institute, it was important to look critically at current and future directions at the Department's activity. Attention is given to development of basic accelerator knowledge, realized at home and throughout international collaborations. Of importance is a steady improvement of metrological and experimental basis for accelerator research. Apart of this, some development tendencies were formulated during 1997, oriented to application fields of accelerators. As examples should be named: - medical applications: a) A serious effort was given to an idea of using the existing compact cyclotron C-30 as a source for creation of a diagnostic centre in Swierk. The proposition was formulated in contact with the Nuclear Medicine Department of the Medical Academy, and the ''Brodno'' General Hospital. In spite of declared medical interest in such an installation, the project was not approved, due to lack of proper financial support. b) Model measurements and verification of theoretical assumptions and calculations oriented on the design of a very short, high-gradiented acceleration structure for the low energy accelerator COLINE/1000 were done. This project will enable us to achieve ''source - isocentre distance'', of 1000 mm, instead of existing 800 mm. This is important for therapy. In 1998, this work will be supported by the State Committee for Scientific Research. c) Preliminary discussions, and design approach were undertaken in collaboration with the Centre of Oncology, for elaboration of a movable low-energy accelerator with electron beam output, matched to inter operational irradiation during surgical therapy of tumours. - applications in radiation technology: Comparison of isotope and machine radiation sources indicates that, under Polish conditions it is reasonable to use purpose-oriented high power accelerators. The working group composed of specialists from IChTJ and IPJ prepared the

Department of Nuclear Reactions: Overview

Full text: The Department of Nuclear Reactions had a very productive year. The following reports cover three major domains of our activities: nuclear, material and atomic physics. One of the current questions in modern nuclear physics is question of the phase transitions in nuclear matter. Our physicists, the members of the ALADIN Collaboration at Gesellschaft fuer Schwerionenforschung, participated in new experiments exploring properties of highly excited nuclear matter and the phenomenon of the liquid - gas phase transition. The experiments yielded a number of important results. Details can be found in the three short reports presented in this volume. Structure of a nucleon is another important subject of nuclear science research. In the last year energy region of Δ resonance has been investigated by means of charge exchange reaction. The experiment was performed at Laboratory National Saturne in Saclay by SPESIV-π collaboration consisting of physicist from Institute of Nuclear Physics Orsay, Niels Bohr Institute Copenhagen and from our Department. The main achievement of the experiment was evidence for a Δ - hole attraction in the spin longitudinal channel. Reactions induced by radioactive ion beams such as 6 He recently attract a lot of interest. There exist some evidences that the 6 He nucleus has a two-neutron halo structure similar to that well established for 11 Li. An analysis of 6 He + 4 He scattering data reported in this volume revealed some similarities between the loosely bound 6 Li nucleus and the neutron rich 6 He. Research in material physics has focused on two basic topics: a crystallographic model of uranium dioxide, a material currently used as a nuclear fuel and transformations of defects in GaAs crystals at low temperature. The investigations have been carried out in a wide collaboration with scientists from the University of Jena, Research Center Karlsruhe and Centre de Spectrometrie Nucleaire Orsay. Some experiments have been performed at

2018-01-01

Cornea endothelial cells (CEnCs) tissue engineering is a great challenge to repair diseased or damaged CEnCs and require an appropriate biomaterial to support cell proliferation and differentiation. Biomaterials for CEnCs tissue engineering require biocompatibility, tunable biodegradability, transparency, and suitable mechanical properties. Silk fibroin-based film (SF) is known to meet these factors, but construction of functionalized graft for bioengineering of cornea is still a challenge. Herein, lysophosphatidic acid (LPA) is used to maintain and increase the specific function of CEnCs. The LPA and SF composite film (LPA/SF) was fabricated in this study. Mechanical properties and in vitro studies were performed using a rabbit model to demonstrate the characters of LPA/SF. ATR-FTIR was characterized to identify chemical composition of the films. The morphological and physical properties were performed by SEM, AFM, transparency, and contact angle. Initial cell density and MTT were performed for adhesion and cell viability in the SF and LPA/SF film. Reverse transcription polymerase chain reactions (RT-PCR) and immunofluorescence were performed to examine gene and protein expression. The results showed that films were designed appropriately for CEnCs delivery. Compared to pristine SF, LPA/SF showed higher biocompatibility, cell viability, and expression of CEnCs specific genes and proteins. These indicate that LPA/SF, a new biomaterial, offers potential benefits for CEnCs tissue engineering for regeneration. PMID:29710848

Graduate Medical Education Funding and Curriculum in Physical Medicine and Rehabilitation: A Survey of Physical Medicine and Rehabilitation Department Chairs.

Perret, Danielle; Knowlton, Tiffany; Worsowicz, Gregory

2018-03-01

This national survey highlights graduate medical education funding sources for physical medicine and rehabilitation (PM&R) residency programs as well as perceived funding stability, alignment of the current funding and educational model, the need of further education in postacute care settings, and the practice of contemporary PM&R graduates as perceived by PM&R department/division chairs. Approximately half of the reported PM&R residency positions seem to be funded by Centers of Medicare and Medicaid Services; more than 40% of PM&R chairs believe that their residency program is undersized and nearly a quarter feel at risk for losing positions. A total of 30% of respondents report PM&R resident experiences in home health, 15% in long-term acute care, and 52.5% in a skilled nursing facility/subacute rehabilitation facility. In programs that do not offer these experiences, most chairs feel that this training should be included. In addition, study results suggest that most PM&R graduates work in an outpatient setting. Based on the results that chairs strongly feel the need for resident education in postacute care settings and that most graduates go on to practice in outpatient settings, there is a potential discordance for our current Centers of Medicare and Medicaid Services graduate medical education funding model being linked to the acute care setting.

Classificatory multiplicity: intimate partner violence diagnosis in emergency department consultations.

Science.gov (United States)

Olive, Philippa

2017-08-01

To explore the naming, or classification, of physical assaults by a partner as 'intimate partner violence' during emergency department consultations. Research continues to evidence instances when intimate partner physical violence is 'missed' or unacknowledged during emergency department consultations. Theoretically, this research was approached through complexity theory and the sociology of diagnosis. Research design was an applied, descriptive and explanatory, multiple-method approach that combined qualitative semistructured interviews with service-users (n = 8) and emergency department practitioners (n = 9), and qualitative and quantitative document analysis of emergency department health records (n = 28). This study found that multiple classifications of intimate partner violence were mobilised during emergency department consultations and that these different versions of intimate partner violence held different diagnostic categories, processes and consequences. The construction of different versions of intimate partner violence in emergency department consultations could explain variance in people's experiences and outcomes of consultations. The research found that the classificatory threshold for 'intimate partner violence' was too high. Strengthening systems of diagnosis (identification and intervention) so that all incidents of partner violence are named as 'intimate partner violence' would reduce the incidence of missed cases and afford earlier specialist intervention to reduce violence and limit its harms. This research found that identification of and response to intimate partner violence, even in contexts of severe physical violence, was contingent. By lowering the classificatory threshold so that all incidents of partner violence are named as 'intimate partner violence', practitioners could make a significant contribution to reducing missed intimate partner violence during consultations and improving health outcomes for this population.

Telemedicine allows patients to connect with healthcare providers remotely. It has recently expanded to evaluate low-acuity illnesses such as pharyngitis by using patients' personal communication devices. The purpose of our study was to compare the telemedicine-facilitated physical examination with an in-person examination in emergency department (ED) patients with sore throat. This was a prospective, observational, blinded diagnostic concordance study of patients being seen for sore throat in a 60,000-visit Midwestern academic ED. A telemedicine and a face-to-face examination were performed independently by two advanced practice providers (APP), blinded to the results of the other evaluator. The primary outcome was agreement on pharyngeal redness between the evaluators, with secondary outcomes of agreement and inter-rater reliability on 14 other aspects of the pharyngeal physical examination. We also conducted a survey of patients and providers to evaluate perceptions and preferences for sore throat evaluation using telemedicine. Sixty-two patients were enrolled, with a median tonsil size of 1.0. Inter-rater agreement (kappa) for tonsil size was 0.394, which was worse than our predetermined concordance threshold. Other kappa values ranged from 0 to 0.434, and telemedicine was best for detecting abnormal coloration of the palate and tender superficial cervical lymph nodes (anterior structures), but poor for detecting abnormal submandibular lymph nodes or asymmetry of the posterior pharynx (posterior structures). In survey responses, telemedicine was judged easier to use and more comfortable for providers than patients; however, neither patients nor providers preferred in-person to telemedicine evaluation. Telemedicine exhibited poor agreement with the in-person physical examination on the primary outcome of tonsil size, but exhibited moderate agreement on coloration of the palate and cervical lymphadenopathy. Future work should better characterize the importance of

Laboratory Experiments in Physics for Modern Astronomy With Comprehensive Development of the Physical Principles

CERN Document Server

Golden, Leslie

2013-01-01

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.

Building Undergraduate Physics Programs for the 21st Century

Science.gov (United States)

Hilborn, Robert

2001-04-01

Undergraduate physics programs in the United States are under stress because of changes in the scientific and educational environment in which they operate. The number of undergraduate physics majors is declining nationwide; there is some evidence that the "best" undergraduate students are choosing majors other than physics, and funding agencies seem to be emphasizing K-12 education. How can physics departments respond creatively and constructively to these changes? After describing some of the details of the current environment, I will discuss the activities of the National Task Force on Undergraduate Physics, supported by the American Institute of Physics, the America Physical Society, the American Association of Physics Teachers and the ExxonMobil Foundation. I will also present some analysis of Task Force site visits to departments that have thriving undergraduate physics programs, pointing out the key features that seem to be necessary for success. Among these features are department-wide recruitment and retention efforts that are the theme of this session.

Best Practices in Physics Program Assessment: Should APS Provide Accreditation Standards for Physics?

Science.gov (United States)

Hodapp, Theodore

The Phys21 report, ``Preparing Physics Students for 21st Century Careers,'' provides guidance for physics programs to improve their degree programs to make them more relevant for student career choices. Undertaking such changes and assessing impact varies widely by institution, with many departments inventing assessments with each periodic departmental or programmatic review. American Physical Society has embarked on a process to integrate information from Phys21, the results of other national studies, and educational research outcomes to generate a best-practices guide to help physics departments conduct program review, assessment, and improvement. It is anticipated that departments will be able to use this document to help with their role in university-level accreditation, and in making the case for improvements to departmental programs. Accreditation of physics programs could stem from such a document, and I will discuss some of the thinking of the APS Committee on Education in creating this guide, and how they are advising APS to move forward in the higher education landscape that is increasingly subject to standards-based evaluations. I will describe plans for the design, review, and dissemination of this guide, and how faculty can provide input into its development. This material is based upon work supported by the National Science Foundation under Grant No. 1540570. Opinions expressed do not necessarily reflect those of the NSF.

A Department of Atmospheric and Planetary Sciences at Hampton University

With this presentation we discuss the status of plans for a Department of Atmospheric and Planetary Sciences at Hampton University. Hampton University is a privately endowed, non-profit, non-sectarian, co-educational, and historically black university with 38 baccalaureate, 14 masters, and 4 doctoral degree programs. The graduate program in physics currently offers advanced degrees with concentration in Atmospheric Science. The 10 students now enrolled benefit substantially from the research experience and infrastructure resident in the university's Center for Atmospheric Sciences (CAS), which is celebrating its tenth anniversary. Promoting a greater diversity of participants in geosciences is an important objective for CAS. To accomplish this, we require reliable pipelines of students into the program. One such pipeline is our undergraduate minor in Space, Earth, and Atmospheric Sciences (SEAS minor). This minor concentraton of study is contributing to awareness of geosciences on the Hampton University campus, and beyond, as our students matriculate and join the workforce, or pursue higher degrees. However, the current graduate program, with its emphasis on physics, is not necessarily optimal for atmospheric scientists, and it limits our ability to recruit students who do not have a physics degree. To increase the base of candidate students, we have proposed creation of a Department of Atmospheric and Planetary Sciences, which could attract students from a broader range of academic disciplines. The revised curriculum would provide for greater concentration in atmospheric and planetary sciences, yet maintain a degree of flexibility to allow for coursework in physics or other areas to meet the needs of individual students. The department would offer the M.S. and Ph.D. degrees, and maintain the SEAS minor. The university's administration and faculty have approved our plan for this new department pending authorization by the university's board of trustees, which will

Full text:Due to financial shortages, the Extensive Research Program ''Isotopes and Accelerators'' did not come into effect. This in consequence limited the scope of new design and construction works. As the most important topic remained the continuation of work on Ordered Project for new therapeutical accelerator ''6/15''. It has to be emphasized that during realization of this task, several significant modifications were introduced to get a final solution better matched to future implementation of the prototype. The initially adopted ''classical'' solution of accelerating structure with separate bunching and accelerating sections, was replaced by a single mechanical unit with both incorporated functional subsystems. This solution is more convenient for future production and servicing, but in order to cover the broad range of energy variation is was necessary to recalculate the beam dynamics and to find the method for internal phase correction. Another important feature was an additional design of two possible injection systems, the first with a diode gun for 40 keV energy, and the second one with triode gun 15-20 keV. These solutions provide a contingency for - two production versions of an accelerator equipped with different RF power systems - klystron or magnetron. Substantial effort was directed to completion and operation of an experimental facility for testing accelerating structures. This facility is equipped with a RF high - power source in the form of 6 MW klystron, and high-vacuum pumping system. External apparatus connected to the facility are - magnetic spectrometer and computerized water phantom, which enable the diagnostics of accelerated electron beam. Several structure models were tested, and for the first time an electron energy in the vicinity of 15 MeV was registered. Other important subjects in (he Department's activity were: * Implementation of new versions of MC codes, for analysis of electron and photon beams distribution at the output of

(full text) During the last year our activities were spread over the three major domains: nuclear, atomic and material physics. The nuclear physics experimental programme covered a broad range of nuclear reactions induced by light and heavy ions. New experiments were performed at the compact C-30 cyclotron at Swierk, at University of Jyvaeskylae, GSI Darmstadt, LN Saturne. Prospects for future experiments on nucleon structure at Forschungszentrum Juelich were open. The collaboration with INR Kiev was tightened and work was done in order to prepare experiments at the C-200 heavy ion cyclotron in Warsaw. An effort to install the ion guide isotope separator on line (IGISOL) at the C-200 cyclotron has also to be mentioned A half a year stay of Dr. Nicholas Keeley in the Department, who received The Royal Society/Polish Academy of Science grant, resulted in many interesting results on breakup of light nuclei. Details can be found in the short abstracts presented in this report. As far as atomic physics is concerned, the activity of a group lead by Prof. Marian Jaskola yielded various new results. The experiments were performed at the University of Erlangen, in close collaboration with the Pedagogical University in Kielce and the University of Basel. Fast neutrons generated in the 3 H(d,n) 4 He reaction induced by the 2 MeV deuteron beam from the Van der Graaff accelerator at the Department were used to calibrate solid state-nuclear-track detectors. This was a very good year for material physics research: Jan Kaczanowski and Slawomir Kwiatkawski received Ph.D. degrees based on dissertation research performed in the material physics research programme, while Pawel Kolodziej completed his MSc. thesis in collaboration with the Institute of Electronic Materials Technology in Warsaw, Research Center Karlsruhe, University of Jena and CSNSM Orsay many results were obtained.

Utility of the History and Physical Examination in the Detection of Acute Coronary Syndromes in Emergency Department Patients

Directory of Open Access Journals (Sweden)

Zachary DW Dezman

2017-05-01

Full Text Available Chest pain accounts for approximately 6% of all emergency department (ED visits and is the most common reason for emergency hospital admission. One of the most serious diagnoses emergency physicians must consider is acute coronary syndrome (ACS. This is both common and serious, as ischemic heart disease remains the single biggest cause of death in the western world. The history and physical examination are cornerstones of our diagnostic approach in this patient group. Their importance is emphasized in guidelines, but there is little evidence to support their supposed association. The purpose of this article was to summarize the findings of recent investigations regarding the ability of various components of the history and physical examination to identify which patients presenting to the ED with chest pain require further investigation for possible ACS. Previous studies have consistently identified a number of factors that increase the probability of ACS. These include radiation of the pain, aggravation of the pain by exertion, vomiting, and diaphoresis. Traditional cardiac risk factors identified by the Framingham Heart Study are of limited diagnostic utility in the ED. Clinician gestalt has very low predictive ability, even in patients with a non-diagnostic electrocardiogram (ECG, and gestalt does not seem to be enhanced appreciably by clinical experience. The history and physical alone are unable to reduce a patient’s risk of ACS to a generally acceptable level (<1%. Ultimately, our review of the evidence clearly demonstrates that “atypical” symptoms cannot rule out ACS, while “typical” symptoms cannot rule it in. Therefore, if a patient has symptoms that are compatible with ACS and an alternative cause cannot be identified, clinicians must strongly consider the need for further investigation with ECG and troponin measurement.
