  1. CENS - Annual Report 2002

    International Nuclear Information System (INIS)

    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

    The wine and beer yeast Dekkera bruxellensis thrives in environments that are harsh and limiting, especially in concentrations with low oxygen and high ethanol. Its different strains' chromosomes greatly vary in number (karyotype). This study isolates two novel centromeric loci (CEN1 and CEN2), which support both the yeast's autonomous replication and the stable maintenance of plasmids. In the sequenced genome of the D. bruxellensis strain CBS 2499, CEN1 and CEN2 are each present in one copy. They differ from the known "point" CEN elements, and their biological activity is retained within ~900-1300 bp DNA segments. CEN1 and CEN2 have features of both "point" and "regional" centromeres: They contain conserved DNA elements, ARSs, short repeats, one tRNA gene, and transposon-like elements within less than 1 kb. Our discovery of a miniature inverted-repeat transposable element (MITE) next to CEN2 is the first report of such transposons in yeast. The transformants carrying circular plasmids with cloned CEN1 and CEN2 undergo a phenotypic switch: They form fluffy colonies and produce three times more biofilm. The introduction of extra copies of CEN1 and CEN2 promotes both genome rearrangements and ploidy shifts, with these effects mediated by homologous recombination (between circular plasmid and genome centromere copy) or by chromosome breakage when integrated. Also, the proximity of the MITE-like transposon to CEN2 could translocate CEN2 within the genome or cause chromosomal breaks, so promoting genome dynamics. With extra copies of CEN1 and CEN2, the yeast's enhanced capacities to rearrange its genome and to change its gene expression could increase its abilities for exploiting new and demanding niches.

    1986-01-01

    The first complete map of the stellar velocity field within 100 arcsec of the nucleus of the bright elliptical galaxy NGC 5128 (Cen A) has been compiled, and complementary long-slit spectra out to 400 arcsec along the optical major axis have been obtained. These data show that the ellipsoidal stellar component is rotating slowly (maximum line-of-sight velocity 40 km/s) approximately perpendicular to the dust lane about a projected axis lying in pa approximately 135 deg and in the opposite sense to that expected if the warp were due to the dust lying in stable orbits round a triaxial potential. The velocity field may be explained by either an effectively stationary oblate triaxial model where the radio jet lies along the major axis perpendicular to the dust lane, or by an effectively stationary prolate model where the jet is not constrained to be perpendicular to the dust lane, but in either case the present warped dust lane configuration must be transient. It is shown that the dust lane can significantly affect the steepness of the rotation curve, the skew of the velocity field, and the magnitude of the dispersion.

    Rizzuto, Aaron C; Zucker, Daniel B

    2011-01-01

    We present an analysis of the WISE photometric data for 829 stars in the Sco-Cen OB2 association, using the latest high-mass membership probabilities. We detect infrared excesses associated with 135 BAF-type stars, 99 of which are secure Sco-Cen members. There is a clear increase in excess fraction with membership probability, which can be fitted linearly. We infer that 41+-5% of Sco-Cen OB2 BAF stars to have excesses, while the field star excess fraction is consistent with zero. This is the first time that the probability of non-membership has been used in the calculation of excess fractions for young stars. We do not observe any significant change in excess fraction between the three subgroups. Within our sample, we have observed that B-type association members have a significantly smaller excess fraction than A and F-type association members.

  9. Metal rich stars in omega Cen: preliminary FLAMES GTO results

    2004-01-01

    I present preliminary results for a sample of ~700 red giants in omega Cen, observed during the Ital-FLAMES Consortium GTO time in May 2003, for the Bologna Project on omega Cen. Preliminary Fe and Ca abundances confirm previous results: while the metal-poor and intermediate populations show a normal halo alpha-enhancement of [alpha/Fe]=$+0.3, the most metal-rich stars show a significantly lower [alpha/Fe]=+0.1. If the metal-rich stars have evolved within the cluster in a process of self-enrichment, the only way to lower their alpha-enhancement would be SNe type Ia intervention.

  10. Cen A as gamma- and UHE cosmic-ray Source

    2011-01-01

    Cen A has been recently detected in the high-energy (HE) and very high energy (VHE) gamma-ray domain by Fermi-LAT and H.E.S.S. We review the observed characteristics and suggest a scenario where the VHE emission originates from the vicinity of the black hole. Motivated by the possible association of some ultra-high energy (UHE) cosmic ray (CR) events with Cen A, we further analyze the acceleration efficiency for a number of a mechanisms (including shock and stochastic acceleration), showing that most of them (apart perhaps from shear) have serious difficulties in accelerating protons beyond a few $10^{19}$ eV.

  16. Managing nuclear knowledge: A SCK-CEN Concern

    International Nuclear Information System (INIS)

    Full text: Managing knowledge can be seen as the processes governing the creation, the dissemination and the utilisation of knowledge. Any organisation and specially a research centre will need a continuously updated body of knowledge as a basis of its sustained existence. Since its very beginning, SCK-CEN has always been a knowledge-based organisation aiming to solve topical problems based on experiences in the field, model-oriented experiments and fundamental research. Preserving and enhancing our institutional memory has become vital for the SCK-CEN. We are therefore pursuing our efforts to stimulating preservation and sharing of Nuclear Knowledge. Our knowledge exists in different forms and formats ranging from dispersed pieces of technical or scientific information on different media to a complex reservoir of people with the required educational background, expertise and acquired insights to apply that knowledge safely and effectively. SCK-CEN decided in 2001 to tackle this strategic concern by adopting a practical knowledge management (KM) approach. Our programme started in 2002 is built on 'what already exists'. KM activities were identified all over our organisation - building databases, assembling nuclear and technical information, implementing QA procedures, conducting training, writing publications - so that every researcher or technical staff can lay claim to it. However, a coordinated approach to Knowledge Management requires an efficient re-use of the recorded knowledge and an effective transfer of the available knowledge. This approach ensures an added value to our research work and guarantees on the long term the preservation of our institutional memory. The objective of the KM programme is the continuous improvement of the information management coupled with the elicitation of tacit knowledge, the stimulation of collaboration and the knowledge transfer. KM also enhances the information objects by adding or linking related additional information and

  17. MUSE discovers perpendicular arcs in Cen A inner filament

    Hamer, Stephen; Combes, Francoise; Salomé, Quentin

    2014-01-01

    Evidence of AGN interaction with the intergalactic medium is observed in some galaxies and many cool core clusters. Radio-jets are suspected to dig large cavities into the surrounding gas. In most cases, very large optical filaments (several kpc) are also seen all around the central galaxy. The origin of these filaments is still not understood. Star forming regions are sometimes observed inside the filaments and are interpreted as evidence of positive feedback (AGN-triggered star formation). Cen A is a very nearby galaxy with huge optical filaments aligned with AGN radio-jet direction. Here, we search for line ratio variations along the filaments, kinematic evidence of shock-broadend line widths and large scale dynamical structures. We observe a 1'x1' region around the inner filament of Cen A with MUSE on the VLT during the Science Verification period. The brightest lines are the Halpha, [NII], [OIII] and [SII]. MUSE shows that the filaments are made of clumpy structures inside a more diffuse medium aligned w...

  18. The Hard X-ray Emission of Cen A

    CERN Document Server

    Beckmann, V; Lubinski, P; Soldi, S; Terrier, R

    2011-01-01

    The radio galaxy Cen A has been detected all the way up to the TeV energy range. This raises the question about the dominant emission mechanisms in the high-energy domain. Spectral analysis allows us to put constraints on the possible emission processes. Here we study the hard X-ray emission as measured by INTEGRAL in the 3-1000 keV energy range, in order to distinguish between a thermal and non-thermal inverse Compton process. The hard X-ray spectrum of Cen A shows a significant cut-off at energies Ec = 434 (+106 -73) keV with an underlying power law of photon index 1.73 +- 0.02. A more physical model of thermal Comptonisation (compPS) gives a plasma temperature of kT = 206+-62 keV within the optically thin corona with Compton parameter y = 0.42 (+0.09 -0.06). The reflection component is significant at the 1.9 sigma level with R = 0.12 (+0.09 -0.10), and a reflection strength R>0.3 can be excluded on a 3 sigma level. Time resolved spectral studies show that the flux, absorption, and spectral slope varied in ...

  19. A Bayesian approach to the modelling of alpha Cen A

    CERN Document Server

    Bazot, M; Christensen-Dalsgaard, J

    2012-01-01

    Determining the physical characteristics of a star is an inverse problem consisting in estimating the parameters of models for the stellar structure and evolution, knowing certain observable quantities. We use a Bayesian approach to solve this problem for alpha 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,... 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, either using two 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 resul...

    Full Text Available O PRESENTE artigo resume parte dos resultados de um amplo projeto sobre o Brasil ante cenários internacionais possíveis. 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.

  3. Managing Nuclear Knowledge: a challenge for SCK-CEN

    International Nuclear Information System (INIS)

    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

  4. Education and Training possibilities at the Belgian Nuclear Research Centre SCK-CEN

    International Nuclear Information System (INIS)

    Thanks to its thorough experience in the field of peaceful applications of nuclear science and technology SCK-CEN has garnered a reputation as an outstanding centre of not only research, but also education and training (E and T). The E and T activities at SCK-CEN cover a. o. reactor physics, reactor operation, reactor engineering, radiation protection, decommissioning and waste management. Our courses are directed to the nuclear industry, the medical and the non-nuclear industry, national and international policy organizations, the academic world and the general public. E and T programs are also organized in cooperation with universities, technical universities, nuclear power plants and public and private health services. In addition, the SCK-CEN is involved in international E and T research networks and programs such as ENETRAP, EUTERP, EUNDETRAF, CETRAD, BNEN and ENEN. Next to courses, SCK-CEN also offers students the possibility to perform their research work at our laboratories. Final-year students and Ph.D. candidates can enter a programme defined by an SCK-CEN mentor, in close collaboration with a university promotor. Post-docs are mainly recruited in specialised research domains that reflect the priority programmes and R and D topics of our institute

  5. CenH3 evolution reflects meiotic symmetry as predicted by the centromere drive model.

    Science.gov (United States)

    Zedek, František; Bureš, Petr

    2016-09-15

    The centromere drive model explaining rapid evolution of eukaryotic centromeres predicts higher frequency of positive selection acting on centromeric histone H3 (CenH3) in clades with asymmetric meiosis compared to the clades with only symmetric meiosis. However, despite the impression one might get from the literature, this key prediction of the centromere drive model has not only never been confirmed, but it has never been tested, because all the previous studies dealt only with the presence or absence instead of the frequency of positive selection. To provide evidence for or against different frequencies of positively selected CenH3 in asymmetrics and symmetrics, we have inferred the selective pressures acting on CenH3 in seventeen eukaryotic clades, including plants, animals, fungi, ciliates and apicomplexa, using codon-substitution models, and compared the inferred frequencies between asymmetrics and symmetrics in a quantitative manner. We have found that CenH3 has been evolving adaptively much more frequently in clades with asymmetric meiosis compared with clades displaying only symmetric meiosis which confirms the prediction of centromere drive model. Our findings indicate that the evolution of asymmetric meiosis required CenH3 to evolve adaptively more often to counterbalance the negative consequences of centromere drive.

  7. The Dispersal of Young Stars and the Greater Sco-Cen Association

    CERN Document Server

    Mamajek, E E

    2001-01-01

    We review topics related to the dispersal of young stars from their birth-sites, and focus in particular on the entourage of young stars related to the ongoing star-formation event in the Sco-Cen OB association. We conduct a follow-up kinematic study to that presented in Mamajek, Lawson, & Feigelson (2000; ApJ 544, 356) amongst nearby, isolated, young stars. In addition to the eta Cha and TW Hya groups, we find several more intriguing Sco-Cen outlier candidates: most notably beta Pic, PZ Tel, HD 199143, and HD 100546. We discuss the connection between Sco-Cen and the southern ``150 pc Conspiracy'' molecular clouds, and in particular, Corona Australis. The kinematic evidence suggests that many of the nearby, isolated ~10 Myr-old stars were born near Sco-Cen during the UCL and LCC starbursts 10-15 Myr ago. We hypothesize that these stars inherited 5-10 km/s velocities moving away from Sco-Cen, either through molecular cloud turbulence, or through formation in molecular clouds associated with the expanding S...

  8. GeoCENS: a geospatial cyberinfrastructure for the world-wide sensor web.

    Science.gov (United States)

    Liang, Steve H L; Huang, Chih-Yuan

    2013-01-01

    The world-wide sensor web has become a very useful technique for monitoring the physical world at spatial and temporal scales that were previously impossible. Yet we believe that the full potential of sensor web has thus far not been revealed. In order to harvest the world-wide sensor web's full potential, a geospatial cyberinfrastructure is needed to store, process, and deliver large amount of sensor data collected worldwide. In this paper, we first define the issue of the sensor web long tail followed by our view of the world-wide sensor web architecture. Then, we introduce the Geospatial Cyberinfrastructure for Environmental Sensing (GeoCENS) architecture and explain each of its components. Finally, with demonstration of three real-world powered-by-GeoCENS sensor web applications, we believe that the GeoCENS architecture can successfully address the sensor web long tail issue and consequently realize the world-wide sensor web vision.

  13. Ghost in the time series: no planet for Alpha Cen B

    Rajpaul, Vinesh; Roberts, Stephen J

    2015-01-01

    We re-analyse the publicly available radial velocity (RV) measurements for Alpha Cen B, a star hosting an Earth-mass planet candidate, Alpha Cen Bb, with 3.24 day orbital period. We demonstrate that the 3.24 d signal observed in the Alpha Cen B data almost certainly arises from the window function (time sampling) of the original data. We show that when stellar activity signals are removed from the RV variations, other significant peaks in the power spectrum of the window function are coincidentally suppressed, leaving behind a spurious yet apparently-significant 'ghost' of a signal that was present in the window function's power spectrum to begin with. Even when fitting synthetic data with time sampling identical to the original data, but devoid of any genuine periodicities close to that of the planet candidate, the original model used to infer the presence of Alpha Cen Bb leads to identical conclusions: viz., the 3$\\sigma$ detection of a half-a-metre-per-second signal with 3.236 day period. Our analysis unde...

    Characterization of the aerosolized dose emitted from a nebulized system can be determined using CEN (prEN13544-1) methodology and more recently with a Next Generation Impactor (NGI), but evaporative effects can influence the results. We have investigated these characteristics using different flows and cooling with the NGI and compared the results to the standard CEN method using two different nebulizer systems. The NGI was operated using flows of 15 and 30 L min(-1) at room (ROOM) temperature and immediately after cooling at 5 degrees C for 90 min (COLD). Two nebulizer systems, the Sidestream jet nebulizer (SIDE) and the Aeroneb Pro (AERO), were used to nebulize terbutaline sulphate respiratory solution. The CEN method was also used to provide the aerodynamic characteristics of the aerosolized dose from these two nebulizer systems. The mean (SD) mass median aerodynamic diameter (MMAD) using 15COLD, 15ROOM, 30COLD, 30ROOM, and CEN for AERO was 5.0(0.1), 4.1(0.3), 4.4(0.2), 2.0(0.3), and 3.0(1.1) microm, respectively, and 4.2(0.4), 2.6(0.4), 3.5(0.1), 1.7(0.1), and 3.2(0.3) microm for SIDE. The fine particle fraction (FPF), using the NGI, followed the expected trend associated with the corresponding MMAD values, ranging from 48.1 to 70.5% from AERO and 57.3 to 87.8% for SIDE. The mean FPF for AERO and SIDE using the CEN methodology was 72.5 and 63.6%. Overall there was a highly significant difference (p < 0.001) between the different operating conditions for the FPF and MMAD of both nebulizer systems. All methods revealed a significant difference between AERO and SIDE except CEN. Both nebulizer systems were prone to evaporation effects during in vitro testing. Cooling and using a slow flow minimizes evaporation effects with the NGI and should be adopted as the recommended compendial method. The CEN method provides different values to those of the NGI operating conditions and could not differentiate between the two nebulizers. PMID:19392586

    An overview is given of the work that has been done on the standardization of methods for the characterization of biofuels and solid recovered fuels (SRF). For biofuels a complete set of prestandards is available, conversion of pre-standards to standards is in good progress. The development of a standard biocarbon content method based on the {sup 14}C isotope measurement is in good progress. This standard could be an important tool for carbon dioxide trading purposes. CEN is the European Commission for Standardization, TC 335 is the Technical Committee 335 on Solid Biofuels, and TC 343 is the Technical Committee on Solid Recovered Fuels. [Dutch] In de periode september 2005 tot december 2006 zijn Europese standaarden voor de karakterisering van biobrandstoffen beschikbaar gekomen. Voor een aantal parameters is nader onderzoek vereist en deels gaande. Dankzij de ervaring die in Nederland is opgedaan met Nationale Technische Afspraken (NTA's) voor vaste biobrandstoffen heeft onze bijdrage aan de Europese normering de invoering daarvan zeker bespoedigd. De 14C groendeel bepaling begint terrein te winnen en zal in de nabije toekomst ook bij verdere implementatie van het Kyoto protocol een rol gaan spelen.

    High-quality astrometric, spectroscopic, interferometric and, importantly, asteroseismic observations are available for $\\alpha$ Cen A, which is the closest binary star system to earth. Taking all these constraints into account, we study the internal structure of the star by means of theoretical modelling. Using the Aarhus STellar Evolution Code (ASTEC) and the tools of Computational Bayesian Statistics, in particular a Markov chain Monte Carlo algorithm, we perform statistical inferences for the physical characteristics of the star. We find that $\\alpha$ Cen A has a probability of approximately 40\\% of having a convective core. This probability drops to few percents if one considers reduced rates for the $^{14}$N(p,$\\gamma$)$^{15}$O reaction. These convective cores have fractional radii less than 8\\% when overshoot is neglected.

    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.

    2010-01-01

    We report here an investigation of the X-ray eclipse transitions of the high mass X-ray binary pulsar Cen X-3 in different intensity states. Long term light curve of Cen X-3 obtained with RXTE-ASM spanning for more than 5000 days shows strong aperiodic flux variations with low and high states. We have investigated the eclipse transitions of Cen X-3 in different intensity states with data obtained from pointed observations with the more sensitive instruments on board ASCA, BeppoSAX, XMM-Newton, Chandra and RXTE. We found a very clear trend of sharp eclipse transitions in the high state and longer transitions in the low state. This is a confirmation of this feature first observed with the RXTE-ASM but now with much better clarity. From the light curves obtained from several missions, it is seen that the eclipse egress in the low state starts earlier by an orbital phase of 0.02 indicating that the observed X-rays originate from a much larger region. We have also performed spectral analysis of the post-eclipse pa...

    This is an overview of pulsar accretion modeling. The physics of pulsar accretion, i.e., the process of plasma flow onto the neutron star surface, can be constrained from the spectral properties of the X-ray source. We discuss a new implementation of the physical continuum model developed by Becker and Wolff (2007, ApJ 654, 435). The model incorporates Comptonized blackbody, bremsstrahlung, and cyclotron emission. We discuss preliminary results of applying the new tool to the test cases of Suzaku data of Cen X-3 and XTE J1946+274. Cen X-3 is a persistent accreting pulsar with an O-star companion observed during a bright period. XTE J1946+274 is a transient accreting pulsar with a Be companion observed during a dim period. Both sources show spectra that are well described with an empirical Fermi Dirac cutoff power law model. We extend the spectral analysis by making the first steps towards a physical description of Cen X-3 and XTE J1946+274.

    The University of Southern Mississippi has established a coastal ocean observing system in the north-central Gulf of Mexico, where there is a dearth of real-time oceanographic observations on the continental shelf. The development of the Central Gulf of Mexico Ocean Observing System (CenGOOS) follows overall guidelines for the Integrated Ocean Observing System as articulated by Ocean.US, and draft regional guidelines set forth by the Gulf of Mexico Coastal Ocean Observing System Regional Association (GCOOS-RA). The present system consists of a 3-m discus buoy measuring both meteorological and oceanographic parameters that are telemetered to the USM Department of Marine Science every three hours via Globalstar satellite communications. Data are served via a web site (www.cengoos.org). The near-term development of the system will include: Further integration with the coastal and near coastal observatories in the region Deployment of a two station, long range, high frequency radar system for mapping surface currents in the Mississippi Bight Deployment of additional instrumented moorings in the Mississippi Bight Development of a data assimilative nowcast/forecast numerical model of the region Regional database of high resolution multibeam and side-scan sonar data The initial plan for development of CenGOOS was formulated based on input solicited from identified stakeholders, regional priorities identified through opinion surveys conducted by the GCOOS-RA, and guidance from both Ocean.US and GCOOS-RA. An overview of our accomplishments, and vision for the future will be presented. This will include the hardware infrastructure, data management and communications plans and implementation, and other activities to integrate CenGOOS with the other observing systems in the Gulf of Mexico.

  5. Detection of the AM Her type cataclysmic variable V834 Cen at radio wavelengths

    International Nuclear Information System (INIS)

    The first detection is reported of the AM Her type cataclysmic variable system V834 Cen at 8.4 GHz, making it the second AM Her system to be detected at radio wavelengths. The radio emission is variable on time-scales as short as 1 min and reaches peak flux densities of 35 mJy. Longer time-scale variations of order of tens of minutes and levels of 12 mJy may be correlated with binary phase. The emission mechanism is probably an electron-cyclotron maser. (author)

    Karyotypes with an interstitial deletion and a marker chromosome formed from the deleted segment are rare. We identified such a rearrangement in a newborn infant, who presented with macrocephaly, asymmetric square skull, minor facial anomalies, omphalocele, inguinal hernias, hypospadias, and club feet. The karyotype 46,XY,del(5)(pter{r_arrow}p13::cen{r_arrow}qter)/47,XY,+dicr(5)(:p13{r_arrow}cen::p13{r_arrow}cen),del(5)(pter{r_arrow}p13::cen{r_arrow}qter) was identified by banding studies and FISH analysis in the peripheral lymphocytes. One breakpoint on the del(5) maps distal to GDNF, and FISH analysis using an {alpha}-satellite probe suggests that the proximal breakpoint maps within the centromere. The dicentric r(5) consists of two copies of the segment deleted in the del(5), resulting in trisomy of proximal 5p (5p13-cen). The phenotype of the propositus is compared with other trisomy 5p cases and possible mechanisms for the generation of this unique chromosomal rearrangement are discussed. 27 refs., 3 figs.

    2015-01-01

    The systems V949 Cen, V358 Pup, and V1055 Sco are triples comprised of an eclipsing binary orbiting with a distant visual component on a much longer orbit. The first detailed photometric analysis of these interesting systems was performed using also the archival data from Hipparcos, ASAS, SuperWASP, OMC, and Pi Of The Sky surveys. The system V358~Pup was also analysed using the archival ESO spectra and the radial velocities were derived. The analyses of their light curves revealed the physical properties of the eclipsing components, while the interferometric data for these systems obtained during the last century show that the binaries are also weakly gravitationally bounded with the third components on much longer orbits. The photometry was carried out with the robotic telescope FRAM (part of the Pierre Auger Cosmic Ray Observatory), located in Argentina. The BVRI light curves were analysed with the PHOEBE program, yielding the basic physical parameters of the systems and their orbits. V949 Cen and V358 Pup ...

  14. SCK-CEN 2006 barometer on risk perception of the Belgian population

    International Nuclear Information System (INIS)

    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

    Using Subaru/Suprime-Cam wide-field imaging and both Keck/ESI and LBT/MODS spectroscopy, we identify and characterize a compact star cluster, which we term NGC 3628-UCD1, embedded in a stellar stream around the spiral galaxy NGC 3628. The size and luminosity of UCD1 are similar to $\\omega$ Cen, the most luminous Milky Way globular cluster, which has long been suspected to be the stripped remnant of an accreted dwarf galaxy. The object has a magnitude of $i=19.3$ mag (${\\rm L}_{\\rm i}=1.4\\times10^{6}~{\\rm L}_{\\odot}$). UCD1 is marginally resolved in our ground-based imaging, with a half-light radius of $\\sim10$ pc. We measure an integrated brightness for the stellar stream of $i=13.1$ mag, with $(g-i)=1.0$. This would correspond to an accreted dwarf galaxy with an approximate luminosity of ${\\rm L}_i\\sim4.1\\times10^{8}~{\\rm L}_{\\odot}$. Spectral analysis reveals that UCD1 has an age of $6.6$ Gyr , $[\\rm{Z}/\\rm{H}]=-0.75$, an $[{\\alpha}/\\rm{Fe}]=-0.10$. We propose that UCD1 is an example of an $\\omega$ Cen-like...

    We have obtained high-resolution, high S/N spectra for six red giants in omega Cen: three belonging to the recently discovered, metal-rich Red Giant Branch (RGB-a, Pancino et al. 2000) and three to the metal intermediate population (RGB-MInt). Accurate Iron, Copper and alpha-elements (Ca and Si) abundances have been derived and discussed. In particular, we have obtained the first direct abundance determination based on high-resolution spectroscopy for the RGB-a population, =-0.60+/-0.15. Although this value is lower than previous estimates based on Calcium triplet measurements, we confirm that this population is the most metal rich in omega Cen. In addition, we have found a significant difference in the alpha-elements enhancement of the two populations. The three RGB-MInt stars have the expected overabundance, typical of halo and globular clusters stars: =+0.29+/-0.01. The three RGB-a stars show, instead, a significantly lower alpha-enhancement: =+0.10+/-0.04. We have also detected an increasing trend of [Cu/...

    We present the first multiplicity-dedicated long baseline optical interferometric survey of the Scorpius-Centaurus-Lupus-Crux association. We used the Sydney University Stellar Interferometer to undertake a survey for new companions to 58 Sco-Cen B- type stars and have detected 24 companions at separations ranging from 7-130mas, 14 of which are new detections. Furthermore, we use a Bayesian analysis and all available information in the literature to determine the multiplicity distribution of the 58 stars in our sample, showing that the companion frequency is F = 1.35 and the mass ratio distribution is best described as a power law with exponent equal to -0.46, agreeing with previous Sco-Cen high mass work and differing significantly from lower-mass stars in Tau-Aur. Based on our analysis, we estimate that among young B-type stars in moving groups, up to 23% are apparently single stars. This has strong implications for the understanding of high-mass star formation, which requires angular momentum dispersal thr...

    Electronic and magnetic properties of CeN are investigated using first-principles calculations based on density functional theory (DFT) with the LDA + U method. Our results show that CeN is a half-metal. The majority-spin electron band structure has metallic intersections, whereas the minority-spin electron band structure has a semiconducting gap straddling the Fermi level. A small indirect energy gap occurs between X and W. The calculated magnetic moment is 0.99 μB per unit cell.

    We report here an investigation of the X-ray eclipse transitions of the high mass X-ray binary pulsar Cen X-3 in different intensity states.The long term light curve of Cen X-3 obtained with RXTE-ASM spanning more than 5000d shows strong aperiodic flux variations with low and high states.We have investigated the eclipse transitions of Cen X-3 in different intensity states with data obtained from pointed observations with the more sensitive instruments onboard ASCA,BeppoSAX,XMM-Newton,Chandra and RXTE.We found a very clear trend of sharp eclipse transitions in the high state and longer transitions in the low state.This is a confirmation of this feature first observed with the RXTE-ASM but now observed with much better clarity.From the light curves obtained from several missions,it is seen that the eclipse egress in the low state starts earlier by an orbital phase of 0.02 compared to the eclipse egress in the high state indicating that the observed X-rays originate from a much larger region.We have also performed spectral analysis of the post-eclipse part of each observation.From BeppoSAX observations,the out-of-eclipse X-ray flux is found to differ by a factor of~26 during the high and low intensity states while the eclipse count rates differ by a factor of only~ 4.7.This indicates that in the low state,there is an additional scattering medium which scatters some of the source photons towards the observer even when the neutron star is completely eclipsed.We could also resolve the three iron line components using XMM-Newton observation in the low state.By comparing the iron line equivalent width during the high and low states,it is seen that the width of the iron line is relatively large during the low state which supports the fact that significant reprocessing and scattering of X-rays takes place in the low state.

    We present early high resolution spectroscopic observations of the nova V1369 Cen. We have detected an absorption feature at 6695.6 \\AA\\, that we have identified as blue--shifted $^7$Li I $\\lambda$6708 \\AA. The absorption line, moving at -550 km/s, was observed in five high-resolution spectra of the nova obtained at different epochs. On the basis of the intensity of this absorption line we infer that a single nova outburst can inject in the Galaxy $M_{Li} =$ 0.3 - 4.8 $\\times 10^{-10}$ M$_{\\odot}$. Given the current estimates of Galactic nova rate, this amount is sufficient to explain the puzzling origin of the overabundance of Lithium observed in young star populations.

  4. Dose received by the village of the Juragua CEN due to food consumption

    International Nuclear Information System (INIS)

    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

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.

    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.

  10. CEN standard for water-soluble chloride, sodium and potassium in solid bio-fuels; CEN standard for vandoploeseligt chlorid, natrium og kalium i faste biobraendsler

    2002-10-01

    In 2000 a European work of standardization for 'Solid bio-fuels' under CEN/TC 335 was started. In Denmark this work is followed through the Danish mirror committee S-358. Denmark was asked to prepare a draft for a European standard concerning determination of the water-soluble content of chloride, sodium and potassium in solid bio-fuels. The draft should be based on the Danish 'Recommended analysis methods' no. 10 and 11 concerning respectively the determination of the water-soluble content of chloride and the water soluble content of sodium and potassium in solid bio-fuels. The content of chlorine, sodium and potassium in a fuel is important for the use of the fuel, as high contents can contribute significantly to utilisation problems such as corrosion, fouling and slagging in furnaces. The gaseous emissions from the thermal processes may also be affected. Concerning sodium and potassium it is furthermore the content of the water-soluble and readily volatile salts which is problematic in relation with energy conversion processes. Sodium and potassium bound in non-water soluble compounds as clay minerals (silicates) normally will not volatilises during the process and therefore do not contribute to the formation of deposits. A determination of the water-soluble content of sodium and potassium is therefore not an alternative routine method for sodium and potassium, but a separate method for a determination of the 'aggressive' contents of sodium and potassium. For some solid bio-fuels the water-soluble contents will however be equal to the total contents, this goes for instance for potassium in straw. There is a very large variation in the content of chlorine, sodium and potassium for the different types of solid bio-fuel, from the low contents in clean wood to contents in percentage in straw. Knowledge of the content of chlorine, sodium and potassium in a bio-fuel is thus important in relation to e.g. plant design and fuel purchasing

    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. Contudo, outras medidas de conservação são ainda necessárias para se manter a integridade funcional das paisagens e bacias hidrográficas amazônicas. Atuais experimentos em conservação florestal em propriedades privadas, mercados de serviços ambientais e zoneamento agro-ecológico devem ser refinados e multiplicados a fim de se buscar uma conservação extensiva.THE AMAZON is entering an era of rapid changes as new transportation corridors traverse the region, stimulating the expansion of logging and agricultural frontiers.

    We present 237 new spectroscopically confirmed pre-main-sequence K and M-type stars in the young Upper Scorpius subgroup of the Sco-Cen association, the near- est region of recent massive star formation. Using the Wide-Field Spectrograph at the Australian National University 2.3 m telescope at Siding Spring, we observed 397 kinematically and photometrically selected candidate members of Upper Scorpius, and identified new members by the presence of Lithium absorption. The HR-diagram of the new members shows a spread of ages, ranging from ~3-20 Myr, which broadly agrees with the current age estimates of ~5-10 Myr. We find a significant range of Li 6708 equivalent widths among the members, and a minor dependence of HR-diagram position on the measured equivalent width of the Li 6708A line, with members that appear younger having more Lithium. This could indicate the presence of either popu- lations of different age, or a spread of ages in Upper Scorpius. We also use Wide-Field Infrared Survey Explorer data to inf...

    2005-01-01

    We present the first determination of the proper motion of the neutron star low mass X-ray binary {Cen X-4} measured from relative astrometry of the secondary star using optical images at different epochs. We determine the Galactic space velocity components of the system and find them to be significantly different from the mean values that characterize the kinematics of stars belonging to the halo, and the thin and the thick disc of the Galaxy. The high metallicity of the secondary star of the system rules out a halo origin and indicates that the system probably originated in the Galactic disc. A statistical analysis of the galactocentric motion revealed that this binary moves in a highly eccentric ($e\\simeq 0.85\\pm0.1$) orbit with an inclination of $\\simeq 110^\\circ$ to the Galactic plane. The large Galactic space velocity components strongly support that a high natal kick as a result of a supernova explosion could have propelled the system into such an orbit from a birth place in the Galactic disc. The high...

  14. Using Beta Cen to Probe the Photosphere-Wind Connection to B Stars

    Science.gov (United States)

    MacFarlane, Joseph J.

    2005-01-01

    The goal of the project was to probe the connection between the photospheric pulsations and the X-ray production in the stellar winds of B stars. The B1 III star Beta Centauri is a Beta Cephei variable with a high X-ray count rate, and was observed by XMM. Analysis of XMM X-ray spectra showed characteristic plasma temperatures of 0.1, 0.2 and 0.6 keV. Analysis of He-like forbidden-to-intercombination lines was performed to determine the dominant locations of the X-ray emission. At Prism, work focused on developing and upgrading spectral models to calculate forbidden-to-intercombination line ratios using more detailed atomic models than the simple models typically used in the analysis of X-ray spectral lines, thereby allowing us to assess the effects of a broader variety of populating and depopulating channels for energy levels contributing to the observed X-ray line emission. Based on Ne IX lines, the source location was determined to be no farther than 4 stellar radii. Examination of the time variability of the XMM data for Beta Cen showed no significant correlation with the known optical pulsation period for the star, and also did not find any significant periods of variation at X-ray wavelengths.

    2014-01-01

    We accurately determine the fundamental system parameters of the neutron-star X-ray transient Cen X-4 solely using phase-resolved high-resolution UVES spectroscopy. We first determine the radial-velocity curve of the secondary star and then model the shape of the phase-resolved absorption line profiles using an X-ray binary model. The model computes the exact rotationally broadened phase-resolved spectrum and does not depend on assumptions about the rotation profile, limb-darkening coefficients and the effects of contamination from an accretion disk. We determine the secondary star-to-neutron star binary mass ratio to be 0.1755+/-0.0025, which is an order of magnitude more accurate than previous estimates. We also constrain the inclination angle to be 32 (+8; -2) degrees, Combining these values with the results of the radial velocity study gives a neutron star mass of 1.94 (+0.37; -0.85) Msun consistent with previous estimates. Finally, we perform the first Roche tomography reconstruction of the secondary sta...

    2014-01-01

    We present the first optical and infrared polarimetric study of the low mass transient X-ray binary Cen X-4 during its quiescent phase. This work is aimed to search for an intrinsic linear polarisation component in the system emitted radiation that might be due, e.g., to synchrotron emission from a compact jet, or to Thomson scattering with free electrons in an accretion disc. Multiband (BVRI) optical polarimetric observations were obtained during two nights in 2008 at the ESO La Silla 3.6 m telescope (EFOSC2) in polarimetric mode. These observations cover about the 30% of the 15.1 hours orbital period. J-band observations were obtained in 2007 with the NICS (TNG) instrument at La Palma, for a totality of 1 hour observation. We obtained 3-sigma upper limits to the polarisation degree in all the optical bands, with the most constraining one being in the I-band (P<0.5%). No phase-correlated variability has been noticed in all the filters. The J-band observations provided a 6% upper limit on the polarisation ...

    2005-01-01

    In this project we began by identifying the large number of emission lines visible in the XMM-Newton RGS spectra of Beta Cen. A comprehensive analysis of the temperature structure of the hot gas was carried out by simultaneously fitting the data from all the instruments on the spacecraft. This resulted in a measured temperature range of 0.1-0.6 keV. In more detailed analysis, three characteristic plasma temperatures were found: 0.1, 0.2, and 0.6 keV. The research carried out at UW-Eau Claire primarily focused on two aspects of the data: the analysis of the forbidden line to intercombination line ratio for He-like ions and the time variability of the overall X-ray flux as detected in the direct X-ray images of the star. The analysis of the lines from He-like ions indicate that the Ne IX lines are formed no farther than about 4 stellar radii from the star's photosphere, while the N VI lines are formed within 11 stellar radii of the photosphere. X-ray flux variability would be particularly interesting for this star because it is a known Beta Cep-type variable as seen in optical light: similar variation in the X-ray region would forge an interesting link between the two wavebands. Initial analysis of the X-ray flux was complicated by spikes in the count rates early in the observation. Detailed analysis of the spectral characteristics these count rate anomalies indicated that these flares were probably not intrinsic to the star, rather they were contaminations of the data due to the passage of the satellite through soft proton clouds in the Earth's magnetosphere. An analysis of the light curve of the uncontaminated portions of the light curve did not reveal any variation on the known optical period of variation for this star, and a general search for periodic variability also did not find any significant periods of variation.

    A structure with a massive group in its center and a cool expansion outflow outside is studied around the Cen A galaxy with the use of the Hubble Space Telescope observations. It is demonstrated that the dynamics of the flow is dominated by the antigravity of the dark energy background. The density of dark energy in the cell is estimated to be near the global cosmological density. This agrees with our previous result from the neighborhood of the Local group. A notion of the ``Hubble cell'' is introduced as a building block of the local structure of the universe.

    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.

    FLOWERING LOCUS T (FT) and CENTRORADIALIS (CEN) homologs have been implicated in regulation of growth, determinacy and flowering. The roles of kiwifruit FT and CEN were explored using a combination of expression analysis, protein interactions, response to temperature in high-chill and low-chill kiwifruit cultivars and ectopic expression in Arabidopsis and Actinidia. The expression and activity of FT was opposite from that of CEN and incorporated an interaction with a FLOWERING LOCUS D (FD)-like bZIP transcription factor. Accumulation of FT transcript was associated with plant maturity and particular stages of leaf, flower and fruit development, but could be detected irrespective of the flowering process and failed to induce precocious flowering in transgenic kiwifruit. Instead, transgenic plants demonstrated reduced growth and survival rate. Accumulation of FT transcript was detected in dormant buds and stem in response to winter chilling. In contrast, FD in buds was reduced by exposure to cold. CEN transcript accumulated in developing latent buds, but declined before the onset of dormancy and delayed flowering when ectopically expressed in kiwifruit. Our results suggest roles for FT, CEN and FD in integration of developmental and environmental cues that affect dormancy, budbreak and flowering in kiwifruit.

    The high-pressure structural stability of CeN is investigated by experiment and theory. Experiments are carried out by energy-dispersive X-ray diffraction and synchrotron radiation, using a diamond anvil cell, to a maximum pressure of 77GPa. The experimental results are in remarkably good agreement...... with ab initio calculations using the full-potential linear muffin-tin orbital method within the generalized gradient approximation (GGA). The experimental zero pressure bulk modulus is B0=156(3)GPa, the pressure derivative being constrained to B0′=4.00. The corresponding calculated data are B0=158.1GPa...... and B0′=3.3. We report here the first experimental observation of the transformation of CeN from the ambient B1 type crystal structure to the B2 type. The onset of the transition is in the range 65–70GPa, and the relative volume change at the transition is ΔV/V=−10.9(3)%. These data compare well...

    UHECR (Ultra High Cosmic Rays) made by He-like lightest nuclei might be solve main of the AUGER extragalactic clustering: He UHECR cannot arrive from Virgo because the light nuclei fragility and opacity above few Mpc; UHECR signals are clustering along Cen-A spreading as observed by horizontal galactic arms magnetic, along a vertical angles as observed clustered ones. As a consequence UHECR He, being fragile should partially fragment in secondaries at tens EeV multiplet (D,He3,p) almost as it occurs in the very recent UHECR multiplet at 20 EeV along Cen A UHECR clustering. However most remaining UHECR spread group seem to show mild correlations with other gamma (MeV-Al26) galactic sources within a wide angle. Moreover a rare UHECR clustering triplet is overlapping on Vela TeV anisotropy; other nearest galactic gamma sources may show links with UHECR. Therefore UHECR might be also heavy radioactive galactic nuclei as Ni56, Ni57 and Co57,Co60 widely bent from the sources whose radioactivity and decay in flight ...

    Based on the first-principles plane wave ultra-soft pseudo potential (USP) method of density function theory pure N and Ce doped and Ce-N codoping anatase TiO2 supercell models were established, respectively, and calculated their energy in this paper. The calculated results show that the three doping systems compared to the pure anatase TiO2 band gap narrowed which results in red-shift of the optical absorption edges and Ce-N codoped anatase TiO2 have the most obvious visible effect. Meanwhile, synergy is very effective for the separation of electron-hole pairs and the electrons have a better lifespan. Research found that the trend of the donor's movements at the shallow level of Ce-N codoped anatase TiO2 is not obvious. This is due to its very thick shell, resulting in shielding effect of the outer layer of the Ce-4f.

    Full Text Available Abstract Saccharomyces cerevisiae CEN.PK 113-7D is widely used for metabolic engineering and systems biology research in industry and academia. We sequenced, assembled, annotated and analyzed its genome. Single-nucleotide variations (SNV, insertions/deletions (indels and differences in genome organization compared to the reference strain S. cerevisiae S288C were analyzed. In addition to a few large deletions and duplications, nearly 3000 indels were identified in the CEN.PK113-7D genome relative to S288C. These differences were overrepresented in genes whose functions are related to transcriptional regulation and chromatin remodelling. Some of these variations were caused by unstable tandem repeats, suggesting an innate evolvability of the corresponding genes. Besides a previously characterized mutation in adenylate cyclase, the CEN.PK113-7D genome sequence revealed a significant enrichment of non-synonymous mutations in genes encoding for components of the cAMP signalling pathway. Some phenotypic characteristics of the CEN.PK113-7D strains were explained by the presence of additional specific metabolic genes relative to S288C. In particular, the presence of the BIO1 and BIO6 genes correlated with a biotin prototrophy of CEN.PK113-7D. Furthermore, the copy number, chromosomal location and sequences of the MAL loci were resolved. The assembled sequence reveals that CEN.PK113-7D has a mosaic genome that combines characteristics of laboratory strains and wild-industrial strains.

    Full Text Available We conducted the first long-term (60 days, multiwavelength (optical, ultraviolet, and X-ray simultaneous monitoring of Cen X-4 with daily Swift observations, with the goal of understanding variability in the low mass X-ray binary Cen X-4 during quiescence. We found Cen X-4 to be highly variable in all energy bands on timescales from days to months, with the strongest quiescent variability a factor of 22 drop in the X-ray count rate in only 4 days. The X-ray, UV and optical (V band emission are correlated on timescales down to less than 110 s. The shape of the correlation is a power law with index γ about 0.2–0.6. The X-ray spectrum is well fitted by a hydrogen NS atmosphere (kT = 59 − 80 eV and a power law (with spectral index Γ = 1.4 − 2.0, with the spectral shape remaining constant as the flux varies. Both components vary in tandem, with each responsible for about 50% of the total X-ray flux, implying that they are physically linked. We conclude that the X-rays are likely generated by matter accreting down to the NS surface. Moreover, based on the short timescale of the correlation, we also unambiguously demonstrate that the UV emission can not be due to either thermal emission from the stream impact point, or a standard optically thick, geometrically thin disc. The spectral energy distribution shows a small UV emitting region, too hot to arise from the accretion disk, that we identified as a hot spot on the companion star. Therefore, the UV emission is most likely produced by reprocessing from the companion star, indeed the vertical size of the disc is small and can only reprocess a marginal fraction of the X-ray emission. We also found the accretion disc in quiescence to likely be UV faint, with a minimal contribution to the whole UV flux.

    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.

    Context. Origin and evolution of blue stragglers in globular clusters is still a matter of debate. Aims. The aim of the present investigation is to reproduce the evolutionary history of four binary blue stragglers in four different clusters, for which precise values of global parameters are known. Methods. Using the model for cool close binary evolution, developed by one of us (KS), progenitors of all investigated binaries were found and their parameters evolved into the presently observed values. Results. The results show that the progenitors of the binary blue stragglers are cool close binaries with period of a few days, which transform into stragglers by rejuvenation of the initially less massive component by mass transfer from its more massive companion overflowing the inner critical Roche surface. The parameters of V209 from \\omega Cen indicate that the binary is substantially enriched in helium. This is an independent and strong evidence for the existence of the helium rich subpopulation in this cluster...

    Selective screening media for the detection and identification of Aeromonas strains are needed to guide primary isolation procedures in the clinical laboratory. This study compared the selective CromoCen® AGN chromogenic agar medium for the detection and identification of Aeromonas strains that were isolated from various samples against the conventional selective agar media that are commonly used for the isolation of this organism in food, environmental and clinical samples. The Miles and Misra and ecometric methods were used to evaluate the microbiological performance of CromoCen® AGN chromogenic agar medium, which was shown to be satisfactory. A total of 14 reference Aeromonas strains, 44 wild strains and 106 clinical stool specimens were examined using both non-chromogenic selective agars that are commonly used for Aeromonas isolation and CromoCen® AGN agar. The latter exhibited 94.73% sensitivity and 100% specificity for the various samples. On CromoCen® AGN agar medium, Aeromonas formed colonies with light green, greenish and salmon pigments with or without a surrounding wide transparent zone (halo) of 2-3mm in diameter around the entire border. This medium is recommended for the isolation and potential identification of the Aeromonas genus.

  18. Adaptation of methodology to select structural alternatives of one-way slab in residential building to the guidelines of the European Committee for Standardization (CEN/TC 350)

    International Nuclear Information System (INIS)

    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.

  1. Effect of pulse profile variations on measurement of eccentricity in orbits of Cen X-3 and SMC X-1

    CERN Document Server

    Raichur, Harsha

    2009-01-01

    It has long been argued that better timing precision allowed by satelites like Rossi X-ray Timing Experiments (RXTE) will allow us to measure the orbital eccentricity and the angle of periastron of some of the bright persistent high mass X-ray binaries (HMXBs) and hence a possible measurement of apsidal motion in these system. Measuring the rate of apsidal motion allows one to estimate the apsidal motion constant of the mass losing companion star and hence allows for the direct testing of the stellar structure models for these giant stars present in the HMXBs. In the present paper we use the archival RXTE data of two bright persistent sources, namely Cen X-3 and SMC X-1, to measure the very small orbital eccentricity and the angle of periastron. We find that the small variations in the pulse profiles of these sources rather than the intrinsic timing accuracy provided by RXTE, limit the accuracy with which we can measure arrival time of the pulses from these sources. This influences the accuracy with which one...

    2016-01-01

    We present an extensive survey for rapid pulsators among Extreme Horizontal Branch (EHB) stars in omega Cen. The observations performed consist of nearly 100 hours of time-series photometry, as well as low-resolution spectroscopy. We obtained photometry for some 300 EHB stars. Based on the spectroscopy, we derive reliable values of log g, Teff and log(N(He)/N(H)) for 38 targets, as well as estimates of the effective temperature for another nine targets. The survey uncovered a total of five rapid variables with multi-periodic oscillations between 85 and 125 s. Spectroscopically, they form a homogeneous group of hydrogen-rich subdwarf O stars clustered between 48,000 and 54,000 K. For each of the variables we are able to measure between two and three significant pulsations believed to constitute independent harmonic oscillations. In addition to the rapid variables, we found an EHB star with an apparently periodic luminosity variation of ~2700 s, which we tentatively suggest may be caused by ellipsoidal variatio...

  3. First results of the deployment of a SoLid detector module at the SCK-CEN BR2 reactor

    CERN Document Server

    2015-01-01

    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 thr...

    We analysed high-resolution UVES spectra of six stars belonging to the subgiant branch of omega Centauri, and derived abundance ratios of 19 chemical elements (namely Al, Ba, C, Ca, Co, Cr, Cu, Fe, La, Mg, Mn, N, Na, Ni, Sc, Si, Sr, Ti, and Y). A comparison with previous abundance determinations for red giants provided remarkable agreement and allowed us to identify the sub-populations to which our targets belong. We found that three targets belong to a low-metallicity population at [Fe/H]~-2.0 dex, [alpha/Fe]~+0.4 dex and [s/Fe]~0 dex. Stars with similar characteristics were found in small amounts by past surveys of red giants. We discuss the possibility that they belong to a separate sub-population that we name VMP (very metal-poor, at most 5% of the total cluster population), which - in the self-enrichment hypothesis - is the best-candidate first stellar generation in omega Cen. Two of the remaining targets belong to the dominant metal-poor population (MP) at [Fe/H]~-1.7 dex, and the last one to the metal-...

    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.

    We add four warmer late-type supergiants to our previous spectro-interferometric studies of red giants and supergiants. V766 Cen (=HR 5171 A) is found to be a high-luminosity log(L/L_sun)=5.8+-0.4 source of Teff 4290+-760 K and radius 1490+-540 Rsun located close to both the Hayashi and Eddington limits; this source is consistent with a 40 Msun evolutionary track without rotation and current mass 27-36 Msun. It exhibits NaI in emission arising from a shell of radius 1.5 Rphot and a photocenter displacement of about 0.1 Rphot. V766 Cen shows strong extended molecular (CO) layers and a dusty circumstellar background component. This suggest an optically thick pseudo-photosphere at about 1.5 Rphot at the onset of the wind. V766 Cen is a red supergiant located close to the Hayashi limit instead of a yellow hypergiant already evolving back toward warmer Teff as previously discussed. The stars sigma Oph, BM Sco, and HD 206859 are found to have lower luminosities of about log(L/Lsun)=3.4-3.5 and Teff of 3900-5300 K, ...

    2013-01-01

    The physics of accretion during quiescence in low mass X-ray binaries (LMXBs) is poorly understood, yet there are signs that accretion must be happening. Several LMXBs show variability during quiescence, particularly striking is the case of the nearby neutron star Cen X-4. With the goal of unveiling the real nature of its quiescent variability we conducted the first long-term, multiwavelength simultaneous monitoring of Cen X-4, thanks to 60 observations performed by Swift on a daily basis. During those observations, Cen X-4 is highly variable in all energy bands on timescales from days to months, with the strongest quiescent short-term variability detected in the X-ray band, a factor of 22 drop in only 4 days. The X-ray and the UV and optical emission are correlated on timescales down to less than 110 s. The shape of the correlation is a power law with index 0.2-0.6. The X-ray spectrum is well fitted by a hydrogen NS atmosphere (kT=59-80 eV) and a power law (spectral index 1.4-2.0). The spectral shape remains...

    Context: Alpha Centauri is our closest stellar neighbor, at a distance of only 1.3 pc, and its two main components have spectral types comparable to the Sun. This is therefore a favorable target for an imaging search for extrasolar planets. Moreover, indications exist that the gravitational mass of Alpha Cen B is higher than its modeled mass, the difference being consistent with a substellar companion of a few tens of Jupiter masses. Aims: We searched for faint comoving companions to Alpha Cen B. As a secondary objective, we built a catalogue of the detected background sources. Methods: We used the NACO adaptive optics system of the VLT in the J, H, and Ks bands to search for companions to Alpha Cen B. This instrument allowed us to achieve a very high sensitivity to point-like sources, with a limiting magnitude of m\\_Ks ~ 18 at 7" from the star. We complemented this data set with archival coronagraphic images from the HST-ACS instrument to obtain an accurate astrometric calibration. Results: Over the observed...

    Saccharomyces cerevisiae CEN.PK113-5D, a strain auxotrophic for uracil belonging to the CEN.PK family of the yeast S. cerevisiae, was cultured in aerated fed-batch reactor as such and once transformed to express human interleukin-1β (IL-1β), aiming at obtaining high cell densities and optimizing IL-1β production. Three different exponentially increasing glucose feeding profiles were tested, all of them "in theory" promoting respiratory metabolism to obtain high biomass/product yield. A non-structured non-segregated model was developed to describe the performance of S. cerevisiae CEN.PK113-5D during the fed-batch process and, in particular, its capability to metabolize simultaneously glucose and ethanol which derived from the precedent batch growth. Our study showed that the proliferative capacity of the yeast population declined along the fed-batch run, as shown by the exponentially decreasing specific growth rates on glucose. Further, a shift towards fermentative metabolism occurred. This shift took place earlier the higher was the feed rate and was more pronounced in the case of the recombinant strain. Determination of some physiological markers (acetate production, intracellular ROS accumulation, catalase activity and cell viability) showed that neither poor oxygenation nor oxidative stress was responsible for the decreased specific growth rate, nor for the shift to fermentative metabolism.

    International Nuclear Information System (INIS)

    We examine the ejecta evolution of the classical nova V1065 Centauri, constructing a detailed picture of the system based on spectrophotometric observations obtained from 9 to approximately 900 days post-outburst with extensive coverage from optical to mid-infrared wavelengths. We estimate a reddening toward the system of E(B-V) = 0.5 ± 0.1, based upon the B - V color and analysis of the Balmer decrement, and derive a distance estimate of 8.7+2.8-2.1 kpc. The optical spectral evolution is classified as P ofe Nne Ao according to the CTIO Nova Classification system of Williams et al. Photoionization modeling yields absolute abundance values by number, relative to solar of He/H = 1.6 ± 0.3, N/H = 144 ± 34, O/H = 58 ± 18, and Ne/H = 316 ± 58 for the ejecta. We derive an ejected gas mass of Mg = (1.6 ± 0.2) x 10-4 Msun. The infrared excess at late epochs in the evolution of the nova arises from dust condensed in the ejecta composed primarily of silicate grains. We estimate a total dust mass, Md , of order (0.2-3.7) x 10-7 Msun, inferred from modeling the spectral energy distribution observed with the Spitzer IRS and Gemini-South GNIRS spectrometers. Based on the speed class, neon abundance, and the predominance of silicate dust, we classify V1065 Cen as an ONe-type classical nova.

    This diploma thesis examines the issue of the roaming regulation. The goal was to find out whether it had been necessary to regulate roaming prices at the EU level and what consequences it has and will have for individuals in the market - especially consumers, mobile operators, politicians, and also for the single European market. The basic hypothesis is that the roaming regulation will ultimately lead to a reduction in consumer utility, and therefore there is no substantial improvement to th...

    Full Text Available The objective of this work was to discuss the Social Psychology that has been developing in Brazil, placing it in the international theoretical-methodological setting. To achieve this goal, we initially present a brief historical account of the founding of the Brazilian Association of Social Psychology and the Latin American Association of Social Psychology, providing insight into the political struggle that surrounded the emergence of these two organizations and that, to a certain degree, is still present today. We then present the results of research conducted with 150 Brazilian social psychologists concerning the definition of social psychology, the academic training perspective, and the theories used in the conduct of research. The results point to the existence of several contradictions, since, among other matters, they highlight the fact that while most participants advocate research practices tied to a more sociological perspective, the definitions given indicate a more psychological view of social psychology.O objetivo deste trabalho foi discutir a psicologia social que vem sendo desenvolvida no Brasil inserindo-a no cenário teórico-metodológico internacional.

  17. Past research and fabrication conducted at SCK•CEN on ferritic ODS alloys used as cladding for FBR's fuel pins

    2012-09-01

    In the 1960s in the frame of the sodium-cooled fast breeders, SCK•CEN decided to develop claddings made with ferritic stainless materials because of their specific properties, namely a higher thermal conductivity, a lower thermal expansion, a lower tendency to He-embrittlement, and a lower swelling than the austenitic stainless steels. To enhance their lower creep resistance at 650-700 °C arose the idea to strengthen the microstructure by oxide dispersions. This was the starting point of an ambitious programme where both the matrix and the dispersions were optimized. A purely ferritic 13 wt% Cr matrix was selected and its mechanical strength was improved through addition of ferritizing elements. Results of tensile and stress-rupture tests showed that Ti and Mo were the most beneficial elements, partly because of the chi-phase precipitation. In 1973 the optimized matrix composition was Fe-13Cr-3.5Ti-2Mo. To reach creep properties similar to those of AISI 316, different dispersions and methods were tested: internal oxidation (that was not conclusive), and the direct mixing of metallic and oxide powders (Al2O3, MgO, ZrO2, TiO2, ZrSiO4) followed by pressing, sintering, and extrusion. The compression and extrusion parameters were determined: extrusion as hollow at 1050 °C, solution annealing at 1050 °C/15 min, cleaning, cold drawing to the final dimensions with intermediate annealings at 1050 °C, final annealing at 1050 °C, straightening and final aging at 800 °C. The choice of titania and yttria powders and their concentrations were finalized on the basis of their out-of-pile and in-pile creep and tensile strength. As soon as a resistance butt welding machine was developed and installed in a glove-box, fuel segments with PuO2 were loaded in the Belgian MTR BR2. The fabrication parameters were continuously optimized: milling and beating, lubrication, cold drawing (partial and final reduction rates, temperature, duration, atmosphere and furnace).

    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.

    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 rapid proper motion of the α Cen pair (≈3.7 arcsec yr-1) and its location close to the galactic plane on a rich stellar background combine constructively to make them excellent candidates for close stellar conjunctions with more distant stars. Adding new differential astrometry to archival data, we have refined the orbital parameters, barycentric proper motion and parallax of α Cen and compute its apparent trajectory on sky over the coming decades. Based on NTT/SUSI2, NTT/SOFI, and VLT/NACO maps of the field stars around the trajectories of α Cen A and B, we present a catalog of the expected close conjunctions until 2050. An exceptional event will take place in early May 2028, when α Cen A will come within ρmin = 0.015 ± 0.135 arcsec of the mK = 7.8 star 2MASS 14392160-6049528 (hereafter S5). In terms of impact parameter and contrast, this is the most favorable stellar conjunction of α Cen within at least the next three decades. With an angular diameter of θLD = 0.47 ± 0.05 mas, it is likely that S5 is a red giant or supergiant located at several kiloparsecs. The approached stars will act as moving light probes in transmission through the environment of α Cen. The observation of these close conjunctions holds great promises to search for planets and other low mass objects in the α Cen system using photometry and astrometry. The relativistic displacement of the approached star images will be observable, with significant deflection angles in the milliarcsecond range. The small impact parameter of the conjunction with S5 means that this star has a probability of 45% of entering the Einstein ring of α Cen A. The gravitational amplification of the flux of S5 could reach a factor five for the combination of the two lensed images. The proper motion, orbital parameters and parallax of α Cen will be measurable with an extreme accuracy from differential astrometry with the S stars. This will be valuable, for example to prepare the recently announced

Leaf appearance was estimated using a multiplicative model that has a non-linear temperature response function which calculates the daily leaf appearance rate (LAR, leaves day-1 and the accumulated number of leaves (LN from crop emergence to the appearance of the upper last leaf. Leaf appearance was estimated during 100 years in the following scenarios: current climate, +1 °C, +2 °C, +3 °C, +4 °C e +5 °C. The LAR model was estimated with coefficients of the Asterix cultivar in five emergence dates and in two growing seasons (Fall and Spring. Variable of interest was the duration (days of the crop emergence to the appearance of the final leaf number (EM-FLN phase. Statistical analysis was performed assuming a three-factorial experiment, with main effects being climate scenarios, growing seasons, and emergence dates in a completely randomized design using years (one hundred as replications. The results showed that warmer scenarios lead to an increase, in the fall, and a decrease, in the spring growing season, in the duration of the leaf appearance phase, indicating high vulnerability and complexity of the response of potato crop grown in a Subtropical environment to climate change.O objetivo, neste trabalho, foi estimar o impacto de cenários de temperaturas elevadas no desenvolvimento foliar da cultura da batata, em Santa Maria-RS, Brasil.

    Low mass X-ray binaries (LMXBs) show evidence of a global correlation of debated origin between X-ray and optical luminosity. We study for the first time this correlation in two transient LMXBs, the black hole V404 Cyg and the neutron star Cen X-4, over 6 orders of magnitude in X-ray luminosity, from outburst to quiescence. After subtracting the contribution from the companion star, the Cen X-4 data can be described by a single power law correlation of the form $L_{opt}\\propto\\,L_{X}^{0.44}$, consistent with disk reprocessing. We find a similar correlation slope for V404 Cyg in quiescence (0.46) and a steeper one (0.56) in the outburst hard state of 1989. However, V404 Cyg is about $160-280$ times optically brighter, at a given $3-9$ keV X-ray luminosity, compared to Cen X-4. This ratio is a factor of 10 smaller in quiescence, where the normalization of the V404 Cyg correlation also changes. We show that once the bolometric X-ray emission is considered and the known main differences between V404 Cyg and Cen X...

    Context: Type Ia supernova observations on scales of thousands of Mpc show that the global expansion of the universe is accelerated by antigravity produced by the enigmatic dark energy contributing 3/4 of the total energy of the universe. Aims: Does antigravity act on small scales as well as large? As a continuation of our efforts to answer this crucial question we combine high accuracy observations of the galaxy flows around the Local Group and the nearby M 81 and CenA groups to observe the effect of the dark energy density on local scales of a few Mpc. Methods: We use an analytical model to describe non-uniform static space-time regions around galaxy groups. In this context it is useful to present the Hubble flow in a normalized Hubble diagram V/Hv Rv vs. r/R_v, where the vacuum Hubble constant Hv depends only on the cosmological vacuum density and the zero-gravity distance Rv depends on the vacuum density and on the mass of the galaxy group. We have prepared the normalized Hubble diagrams for the LG, M 81 and CenA group environments for different values of the assumed vacuum energy density, using a total of about 150 galaxies, for almost all of which the distances have been measured by the HST. Results: The normalized Hubble diagram, where we identify dynamically different regions, is in agreement with the standard vacuum density (Ωv = 0.77~h_70-2), the out-flow of galaxies clearly being controlled by the minimum energy condition imposed by the central mass plus the vacuum density. A high vacuum density 1.6~h_70-2 violates the minimum energy limit, while a low density 0.1~h_70-2 leaves the start of the Hubble flow around 1-2 Mpc with the slope close to the global value obscure. We also consider the subtle relation of the zero-gravity radius Rv to the zero-velocity distance R0 appearing in the usual retarded expansion around a mass M: in a vacuum-dominated flat universe R0 ≈ 0.76 R_v. Conclusions: The normalized Hubble diagram appears to be a good way to

    Full Text Available A crescente oferta de escolha no universo de consumo pode implicar em confusão do consumidor. Frente à falta de uma definição consolidada desse construto, investigou-se a compreensão e conhecimentos acumulados sobre o fenômeno. Utilizou-se o método de teoria fundamentada aplicado a uma revisão sistematizada da literatura, em seleção de 93 artigos publicados na última década. Como resultado, foram identificadas seis compreensões distintas e achados empíricos associados a cada uma delas. Concluiu-se existir uma tendência de compreensão abrangente à trajetória de consumo como um todo, faltando, porém, maior enfoque na confusão relacionada à conectividade do consumidor no cenário multimídia e multicanal. O presente artigo propõe, portanto, uma nova definição do construto e questões a serem exploradas em estudos futuros.

  4. Internal gamma gamma-opacity in Active Galactic Nuclei and the consequences for the TeV observations of M87 and Cen A

    2011-01-01

    Low Luminosity Active Galactic Nuclei (LLAGNs) possess the characteristic features of more luminous Active Galactic Nuclei (AGNs) but exhibit a much lower nuclear Halpha luminosity than their more luminous counterparts. M87 (NGC 4486) and Centaurus A (NGC 5128, CenA) are well-studied nearby LLAGNs. As an additional feature they show gamma-radiation up to TeV (10^{12}eV) energies, but the origin of this radiation is not resolved. The coincident observation of a radio and TeV flare in M87 suggests that the TeV radiation is produced within around 50-100 gravitational radii of the central supermassive black hole, depending on the assumed value of the mass of the black hole. Strong radiation fields can be produced in the central region of an (LL)AGN, e.g., by the accretion flow around the black hole, the jet plasma, or stars closely orbiting the black hole. These radiation fields can lead to the absorption of emitted TeV photons, and in fact high optical depths of such fields can make TeV detection from inner regi...

  6. Human adrenodoxin reductase: Two mRNAs encoded by a single gene on chromosome 17cen → q25 are expressed in steroidogenic tissues

    International Nuclear Information System (INIS)

    Adrenodoxin reductase is a mitochondrial flavoprotein that receives electrons from NADPH, thus initiating the electron-transport chain serving mitochondrial cytochromes P450. The authors have cloned and sequenced two human adrenodoxin reductase cDNAs that differ by the presence of six additional codons in the middle of one clone. The sequence in this region indicates that these six extra codons arise by alternative splicing of the pre-mRNA. Southern blot hybridization patterns of human genomic DNA cut with four restriction enzymes indicate that the human genome has only one gene for adrenodoxin reductase. Analysis of a panel of mouse-human somatic cell hybrids localized this gene to chromosome 17cen → q25. The alternatively spliced mRNA containing the six extra codons represents 10-20% of all adrenodoxin reductase mRNA. The expression of the adrenodoxin reductase gene may be stimulated by pituitary tropic hormones acting through cAMP, but its response is quantitatively much less than the responses of P450scc and adrenodoxin

    The large relative sizes of circumstellar and circumplanetary disks imply that they might be seen in eclipse in stellar light curves. We present photometric and spectroscopic data for a pre-main sequence K5 star (1SWASP J140747.93-394542.6 = ASAS J140748-3945.7), a newly discovered ~0.9 Msun member of the ~16 Myr-old Upper Centaurus-Lupus subgroup of Sco-Cen at a distance of 128+-13 pc. This star exhibited a remarkably long, deep, and complex eclipse event centered on 29 April 2007 (as discovered in SuperWASP photometry, and with portions of the dimming confirmed by ASAS data). At least 5 multi-day dimming events of >0.5 mag are identified, with a >3.3 mag deep eclipse bracketed by two pairs of ~1 mag eclipses symmetrically occurring +-12 days and +-26 days before and after. Hence, significant dimming of the star was taking place on and off over at least a ~54 day period in 2007, and a strong >1 mag dimming event occurring over a ~12 day span. We place a firm lower limit on the period of 850 days (i.e. the o...

  8. On the Optical-X-Ray Correlation from Outburst to Quiescence in Low-mass X-Ray Binaries: The Representative Cases of V404 Cyg and Cen X-4

    Low-mass X-ray binaries (LMXBs) show evidence of a global correlation of debated origin between X-ray and optical luminosity. We study for the first time this correlation in two transient LMXBs, the black hole (BH) V404 Cyg and the neutron star Cen X-4, over six orders of magnitude in X-ray luminosity, from outburst to quiescence. After subtracting the contribution from the companion star, the Cen X-4 data can be described by a single power-law correlation of the form {L}{opt}\\propto {L}{{X}}0.44, consistent with disk reprocessing. We find a similar correlation slope for V404 Cyg in quiescence (0.46) and a steeper one (0.56) in the outburst hard state of 1989. However, V404 Cyg is about 160-280 times optically brighter, at a given 3-9 keV X-ray luminosity, compared to Cen X-4. This ratio is a factor of 10 smaller in quiescence, where the normalization of the V404 Cyg correlation also changes. Once the bolometric X-ray emission is considered and the known main differences between V404 Cyg and Cen X-4 are taken into account (a larger compact object mass, accretion disk size, and the presence of a strong jet contribution in the hard state for the BH system), the two systems lie on the same correlation. In V404 Cyg, the jet dominates spectrally at optical-infrared frequencies during the hard state but makes a negligible contribution in quiescence, which may account for the change in its correlation slope and normalization. These results provide a benchmark to compare with data from the 2015 outburst of V404 Cyg and, potentially, other transient LMXBs as well.

    Highlights: • We develop a MCNPX model of the TAPIRO fast research reactor. • The model has been tested against the result of a late experimental champaign finding on overall agreement. • The source of uncertainties in the nuclear data and in the model assumptions has been discussed. • The model is sufficiently accurate to design irradiation experiment in support to R and D activities on LFR and ADS systems. - Abstract: After Fukushima events, the Italian nuclear program has been redefined leaving space only to activities related to Generation IV nuclear systems. Accordingly with this renewed national scenario, TAPIRO fast reactor facility is gaining a relatively major strategic role. A program is in fact being proposed to host in TAPIRO benchmark experimental activities related to the development of Lead fast reactor and Accelerator Driven Systems. A first step of this program would consist on the validation of neutronic codes, cross section data and reactor models to be adopted for its analysis. Along this line in this work the results of a simulation study has been made relevant to the measurements performed in the SCK-CEN/ENEA experimental campaign carried out in the 1980–1986 period. The calculations have been made using the Monte Carlo MCNPX 2.7.0 Code. In this article the main results are presented and discussed, with particular emphasis on the uncertainties, relevant both to nuclear data and the model layout. The results of this simulation study indicate in particular that TAPIRO's MCNPX model is adequate for the optimization of set-ups of perspective neutron irradiation experiments, this allowing cuts in costs and development time.

Pelo menos 80% dos seus artigos originais e de revisão indexados internacionalmente têm afiliação brasileira e representam cerca de 30% do total da produção científica indexada do Brasil. Porém, essa centralidade nacional é acompanhada de baixo impacto, medido pelo número de citações recebidas nos índices, em comparação ao que obtêm os periódicos dos países desenvolvidos. Embora o desempenho seja compatível com o dos periódicos de países emergentes e a publicação em acesso aberto resulte em cifras extraordinárias de downloads de artigos, boa parte dos periódicos do Brasil enfrenta o desafio de qualificar-se para, de modo concomitante, competir nacional e internacionalmente por manuscritos de melhor qualidade e melhorar o desempenho nos índices internacionais. Essa almejada qualificação requer a superação das limitações inerentes às condições institucionais, de gestão e financiamento nas quais operam e o avanço da profissionalização, internacionalização e inovações nos processos de editoração, publicação e disseminação, alinhados ao estado da arte internacional. Este artigo apresenta um panorama das principais características bibliométricas e de gestão editorial do conjunto dos 400 periódicos do Brasil indexados no SciELO, Scopus e WoS e projeta cenários de mudança na composição atual com a promoção de periódicos de referência internacional e na forma como são avaliados e financiados.

    In the 1960s in the frame of the sodium-cooled fast breeders, SCK-CEN decided to develop claddings made with ferritic stainless materials because of their specific properties, namely a higher thermal conductivity, a lower thermal expansion, a lower tendency to He-embrittlement, and a lower swelling than the austenitic stainless steels. To enhance their lower creep resistance at 650-700 Degree-Sign C arose the idea to strengthen the microstructure by oxide dispersions. This was the starting point of an ambitious programme where both the matrix and the dispersions were optimized. A purely ferritic 13 wt% Cr matrix was selected and its mechanical strength was improved through addition of ferritizing elements. Results of tensile and stress-rupture tests showed that Ti and Mo were the most beneficial elements, partly because of the chi-phase precipitation. In 1973 the optimized matrix composition was Fe-13Cr-3.5Ti-2Mo. To reach creep properties similar to those of AISI 316, different dispersions and methods were tested: internal oxidation (that was not conclusive), and the direct mixing of metallic and oxide powders (Al{sub 2}O{sub 3}, MgO, ZrO{sub 2}, TiO{sub 2}, ZrSiO{sub 4}) followed by pressing, sintering, and extrusion. The compression and extrusion parameters were determined: extrusion as hollow at 1050 Degree-Sign C, solution annealing at 1050 Degree-Sign C/15 min, cleaning, cold drawing to the final dimensions with intermediate annealings at 1050 Degree-Sign C, final annealing at 1050 Degree-Sign C, straightening and final aging at 800 Degree-Sign C. The choice of titania and yttria powders and their concentrations were finalized on the basis of their out-of-pile and in-pile creep and tensile strength. As soon as a resistance butt welding machine was developed and installed in a glove-box, fuel segments with PuO{sub 2} were loaded in Belgian MTR BR2. The fabrication parameters were continuously optimized: milling and beating, lubrication, cold drawing (partial

  15. Mis17 is a regulatory module of the Mis6-Mal2-Sim4 centromere complex that is required for the recruitment of CenH3/CENP-A in fission yeast.

    Directory of Open Access Journals (Sweden)

    Yoshiharu Shiroiwa

    Full Text Available BACKGROUND: The centromere is the chromosome domain on which the mitotic kinetochore forms for proper segregation. Deposition of the centromeric histone H3 (CenH3, CENP-A is vital for the formation of centromere-specific chromatin. The Mis6-Mal2-Sim4 complex of the fission yeast S. pombe is required for the recruitment of CenH3 (Cnp1, but its function remains obscure. METHODOLOGY/PRINCIPAL FINDINGS: Mass spectrometry was performed on the proteins precipitated with Mis6- and Mis17-FLAG. The results together with the previously identified Sim4- and Mal2-TAP precipitated proteins indicated that the complex contains 12 subunits, Mis6, Sim4, Mal2, Mis15, Mis17, Cnl2, Fta1-4, Fta6-7, nine of which have human centromeric protein (CENP counterparts. Domain dissection indicated that the carboxy-half of Mis17 is functional, while its amino-half is regulatory. Overproduction of the amino-half caused strong negative dominance, which led to massive chromosome missegregation and hypersensitivity to the histone deacetylase inhibitor TSA. Mis17 was hyperphosphorylated and overproduction-induced negative dominance was abolished in six kinase-deletion mutants, ssp2 (AMPK, ppk9 (AMPK, ppk15 (Yak1, ppk30 (Ark1, wis4 (Ssk2, and lsk1 (P-TEFb. CONCLUSIONS: Mis17 may be a regulatory module of the Mis6 complex. Negative dominance of the Mis17 fragment is exerted while the complex and CenH3 remain at the centromere, a result that differs from the mislocalization seen in the mis17-362 mutant. The known functions of the kinases suggest an unexpected link between Mis17 and control of the cortex actin, nutrition, and signal/transcription. Possible interpretations are discussed.

    Full Text Available As comunidades tradicionais instaladas às margens do rio Madeira são influenciadas pela estreita relação com a natureza e o conhecimento aprofundado de seus ciclos. O pescado é um dos principais recursos explorados para subsistência e comercialização. Este estudo analisou o perfil socioeconômico e a atividade pesqueira de duas comunidades ribeirinhas do médio rio Madeira, São Carlos e Calama. Entrevistas com questionários semiestruturados foram aplicadas a um membro de cada família de pescadores destas comunidades, entre abril e agosto de 2009, totalizando 189 entrevistados. As questões incluíram o número de pescadores por família, escolaridade, idade, tempo que atua na pesca, associativismo, forma de comercialização, atividades econômicas complementares e rendimento médio mensal por atividade produtiva. Por meio de reuniões coletivas com os pescadores, levantaram-se informações sobre o Conhecimento Ecológico Local (CEL das espécies e o ambiente, conflitos pesqueiros e cenários atuais. Os resultados indicaram que os pescadores destas localidades têm, em média, idade de 39 anos, e exercem a atividade há cerca de 20 anos. Mais de 60% têm apenas o ensino fundamental incompleto. Os principais conflitos estiveram relacionados com a fiscalização considerada inadequada e a falta de área de pesca. A construção dos mapas de cenários mostrou uma expectativa de aumento dos conflitos atribuindo a redução das áreas de pesca e ainda possíveis migrações de pescadores realocados devido à implantação das UHEs Jirau e Santo Antônio.

    Full Text Available O presente artigo trata de uma Pesquisa-Ação, realizada em 2012 no UNIFESO, voltada à criação de novos cenários de aprendizagem. O projeto de pesquisa focalizou a criação de formas de apoio às iniciativas empreendedoras dos estudantes relacionadas ao campo de formação. A fase exploratória confirmou hipótese sobre demanda discente por apoio às suas ideias. A fase principal da pesquisa apontou para um descompasso entre a intenção de participação por parte dos estudantes e efetiva participação destes na ação. Entretanto, apesar da queda da presença discente ao longo do projeto, a proposta obteve representativa adesão de docentes e discentes, numa participação mais qualitativa, que entre outros resultados orientou o grupo para a criação de um empreendimento acadêmico. Um novo cenário de aprendizagem concretizou-se na instituição em 2013, com o desenvolvimento da Solução Empresa Junior de Consultoria, liderada por estudantes dos cursos do Centro de Ciências e Tecnologia.

A técnica de cenários tem sido utilizada em diversas áreas como ferramenta do planejamento estratégico, e foi empregada neste artigo com o objetivo de auxiliar o planejamento da gestão de resíduos sólidos urbanos (RSU em Curitiba. São apresentados dados sobre geração, caracterização e gerenciamento atual dos RSU, bem como dados socioeconômicos de seus habitantes. A caracterização dos resíduos sólidos urbanos em Curitiba indica uma geração de 0,6 kg.hab-1.dia-1, valor considerado baixo em relação à média Brasileira. No entanto, a composição de resíduos recicláveis é de 40% do total destinado ao aterro sanitário. Uma metodologia para a simulação de cenários futuros da produção de RSU em Curitiba foi desenvolvida, e alguns exemplos de prováveis cenários foram construídos e comparados com o intuito de demonstrar uma aplicação da técnica, assim como de contribuir para o gerenciamento dos resíduos sólidos de Curitiba e para o desenvolvimento de estratégias e políticas de gestão. Dentre os cenários simulados para o período de 2008-2020, destaca-se que, para uma redução de 20% do material reciclável, uma economia de R$ 2.410.000,00 e uma redução de 535.00 ton de resíduos sólidos podem ser alcançadas em relação ao cenário atual ("do nothing".In Curitiba, the discussion on solid waste has increased at the popular, academic and political spheres due to the difficulties on finding ways of treatment and disposals to replace the current waste disposition at the Caximba sanitary landfill.

    Full Text Available The objective of this study was to simulate potato (Solanum tuberosum tuber yield in different climate change scenarios of increased carbon dioxide concentration [CO2] and air temperature, considering symmetric and asymmetric increases in minimum and maximum daily air temperatures. Spitters model was used to simulate Asterix cultivar tuber yield considering two growing seasons (spring and fall recommended for Santa Maria, state of Rio Grande do Sul, Brazil. In each growing season, five planting dates were evaluated in climate scenarios of a hundred years with no increase in [CO2] and temperature (current scenario, and in scenarios with doubling [CO2] and temperature increases of 0, 1, 2, 3, 4, 5 and 6ºC. A symmetric increase of 4ºC and an asymmetric increase of 5ºC in air temperature offset the yield beneficial effect of increasing [CO2] during spring, whereas increase in air temperature does not affect potato tuber yield during fall. Anticipating planting date in spring and delaying it in fall decrease the negative impact of the increasing air temperature on potato tuber yield.O objetivo deste trabalho foi simular a produtividade de tubérculos de batata (Solanum tuberosum em diferentes cenários climáticos de aumento da concentração de dióxido de carbono [CO2] e da temperatura do ar, considerando aumentos simétricos e assimétricos nas temperaturas mínimas e máximas diárias do ar.

Unitil the advent of new policy, Cen Chunxuan had performed an extraordinarily important role in the provincial political stage as the first- rank governer, and was compe- tent enough to balance the power of Yuan Shikai the governer of Beiyang Army. Given the reasons, in Chinese history, Cen chunxuan and Yuan Shikai have been tided as "Cen of the South, Yuan of the North". in 1907, Cen Chunxuan' s sudden northern marching in the name of Qingliu Party started furious fight with Yi Kuang and Yuan Shikai, however, the fight was ended in the firements of both Cen and Zhai due to the eliquing. The Empress Dowager Tz' u - hsi' s seem- ingly calm backstage watching actually made this lose -lose consequence, as we say, wars without winner. Through in- vestigating the changing attitude of the Empress Dowager Tz' u - hsi to Cen Chunxuan, the author finds out that instead of simple instigation between the two, many complicated details deserve meditation.

O objetivo deste trabalho foi estimar os impactos das mudanças climáticas sobre a produção leiteira nos estados de Alagoas, Bahia e Sergipe. Os valores do índice de temperatura e umidade (ITU, do declínio da produção de leite (DPL e da redução do consumo alimentar (RCA de vacas leiteiras foram calculados para os cenários climáticos B1 e A1F1 do IPCC. Utilizou-se um modelo multiplicativo para estimar o efeito das alterações de temperatura sobre os valores normais da umidade relativa do ar. Com base em ambos os cenários do IPCC, as regiões produtoras, situadas no norte e litoral do estado da Bahia e áreas litorâneas dos estados de Alagoas e Sergipe, serão afetadas expressivamente em decorrência do aumento do estresse térmico, com reduções marcantes na produção de leite e no consumo alimentar, especialmente de animais com alto potencial genético de produção. Este cenário pode afetar as atuais regiões produtoras dos estados nordestinos, de forma que a exploração leiteira seja limitada aos animais com baixo desempenho produtivo.Milk production is an activity of great importance in the Brazilian context, and it may be directly and indirectly affected if current climate predictions are confirmed until the end of this century.

    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.

This sample contains all cools stars observed with the LETGS presently available to us with integration times sufficiently long to warrant a meaningful spectral analysis. Our sample comprises inactive, moderately active, and hyperactive stars and samples the bulk part of activity levels encountered in coronal X-ray sources. We use the LETGS spectra to carry out density and temperature diagnostics with an emphasis on the H-like and the He-like ions. We find a correlation between line flux ratios of the Lyman-Alpha and He-like resonance lines with the mean X-ray surface flux. We determine densities using the He-like triplets. For active stars we find no significant deviations from the low-density limit for the ions of Ne, Mg, and Si, while the measured line ratios for the i...

    The recent revision of ISO15189 has further strengthened its position as the standard for accreditation for medical laboratories. Both for laboratories and their customers it is important that the scope of such accreditation is clear. Therefore the European co-operation for accreditation (EA) demands that the national bodies responsible for accreditation describe the scope of every laboratory accreditation in a way that leaves no room for doubt about the range of competence of the particular laboratories. According to EA recommendations scopes may be fixed, mentioning every single test that is part of the accreditation, or flexible, mentioning all combinations of medical field, examination type and materials for which the laboratory is competent. Up to now national accreditation bodies perpetuate use of fixed scopes, partly by inertia, partly out of fear that a too flexible scope may lead to over-valuation of the competence of laboratories, most countries only use fixed scopes. The EA however promotes use of flexible scopes, since this allows for more readily innovation, which contributes to quality in laboratory medicine. In this position paper, the Working Group Accreditation and ISO/CEN Standards belonging to the Quality and Regulation Committee of the EFLM recommends using an approach that has led to successful introduction of the flexible scope for ISO15189 accreditation as intended in EA-4/17 in The Netherlands. The approach is risk-based, discipline and competence-based, and focuses on defining a uniform terminology transferable across the borders of scientific disciplines, laboratories and countries.

Dois cenários foram simulados. No primeiro, o uso atual foi mantido numa faixa de mata ciliar de 30 m em toda a extensão dos cursos d'água e de 50 m ao redor das nascentes, de acordo com o Código Florestal. No segundo cenário, como as pastagens ocupavam 30,9 % da área da microbacia, nas encostas mais íngremes, com alto potencial erosivo, as áreas de pastagem foram substituídas por vegetação florestal. As simulações dos dois cenários foram comparadas com as condições do cenário atual em termos de produção de sedimentos. Os cenários geraram diferentes padrões espaciais da produção de sedimentos. Uma redução de 94,0 % na produção de sedimentos foi obtida com a substituição da pastagem por vegetação nativa (cenário 2. No cenário 1, a redução foi de 10,8 %. Esses resultados evidenciam a necessidade de tratar a paisagem em bacias hidrográficas de forma global, identificando as "áreas sensíveis ambientalmente", onde são necessárias práticas de controle dos processos erosivos e não somente práticas de proteção dispensada aos cursos d'água por meio da mata ciliar.The model SWAT (Soil and Water Assessment Tool was used to simulate alternative scenarios of land use in Ribeirão dos Marins watershed, in Piracicaba, State of São Paulo, Brazil, for the biennial period 1999/2000.

A base do conhecimento disponível na literatura indica que a cana-de-açúcar apresentaria uma resposta positiva em relação aos cenários de mudanças climáticas mais prováveis para o Brasil, tanto pela resposta direta da fotossíntese à elevação na concentração do dióxido de carbono quanto ao aumento da eficiência de uso da água. Contudo, é provável que o manejo na cultura necessite de adaptações uma vez que plantas daninhas e doenças poderiam ser favorecidas pelas condições futuras.Based on literature, this paper examines qualitativelly a future scenario for the sugarcane in Brazil. It was done considering the expanding trend of the crop observed over the last decade, the current sector conjuncture, and the down scaled climate change projections for this century. The focus was to associate the scientific findings on the physiology of sugarcane and their responses to the rise in atmospheric CO2 concentration and the water use efficiency with socio-economic prospects for the sugarcane industry in Brazil. Probable effects on weeds, diseases and pest of sugarcane crop were also analysed. Available literature indicates that sugarcane crop would likely show a positive response to probably scenarios of climate change in Brazil due

    The recent revision of ISO15189 has further strengthened its position as the standard for accreditation for medical laboratories. Both for laboratories and their customers it is important that the scope of such accreditation is clear. Therefore the European co-operation for accreditation (EA) demands that the national bodies responsible for accreditation describe the scope of every laboratory accreditation in a way that leaves no room for doubt about the range of competence of the particular laboratories. According to EA recommendations scopes may be fixed, mentioning every single test that is part of the accreditation, or flexible, mentioning all combinations of medical field, examination type and materials for which the laboratory is competent. Up to now national accreditation bodies perpetuate use of fixed scopes, partly by inertia, partly out of fear that a too flexible scope may lead to over-valuation of the competence of laboratories, most countries only use fixed scopes. The EA however promotes use of flexible scopes, since this allows for more readily innovation, which contributes to quality in laboratory medicine. In this position paper, the Working Group Accreditation and ISO/CEN Standards belonging to the Quality and Regulation Committee of the EFLM recommends using an approach that has led to successful introduction of the flexible scope for ISO15189 accreditation as intended in EA-4/17 in The Netherlands. The approach is risk-based, discipline and competence-based, and focuses on defining a uniform terminology transferable across the borders of scientific disciplines, laboratories and countries.

    Full Text Available A articulação da Psicologia com a Educação oportunizou a emergência do psicólogo escolar, profissional que por muito tempo se caracterizou por classificar e ajustar, à escola, os alunos com dificuldades escolares, aplicando o conhecimento psicológico ao contexto escolar. A partir de avanços teóricos e práticos relativos à Psicologia e de uma postura crítica diante da atuação da área nas escolas, a relação Psicologia-Educação se modificou, configurando-se por interdependência de conhecimentos. Nesta nova configuração, a Psicologia Escolar passou a valorizar as relações e o contexto histórico no qual as dificuldades se instalam e, atualmente, caracteriza-se por uma atuação preventiva e relacional que valoriza a participação do professor e o cuidado com sua saúde psíquica. A Psicologia Escolar tem, hoje, o desafio de ampliar seu campo de atuação para outros contextos e níveis educativos e sistematizar ações diferenciadas que promovam o desenvolvimento e a aprendizagem dos envolvidos no cotidiano escolar.

Serão nele confrontados os pensamentos de cinco psicanalistas: Joël Dor, e sua teorização sobre o papel da função paterna e da diferença anatômica entre os sexos na estruturação do sujeito; Pierre Legendre, e sua articulação entre os campos do jurídico e do psíquico na inscrição do ser humano na ordem da filiação; Michel Tort, e sua crítica às teorias de Legendre; Geneviève Delaisi de Parseval, e sua proposta de uma definição mais ampla da família; e, enfim, Sabine Prokhoris, e a sua distinção entre 'sexuação' e 'diferença dos sexos'. Através dessa apresentação, buscar-se-á desmontar os argumentos contrários e indicar a legitimidade da argumentação favorável à filiação homossexual.After situating homoparenthood within the context of the new social and medical practices concerning parenthood and reproduction, the article presents a scenario of the contemporary French debate on this issue. The thinking of five psychoanalysts on this matter will be broached : Joël Dor and his theory about the role of the function of the father and about the anatomic difference between sexes in the structure process of the subject; Pierre Legendre and his articulation between the fields of law and the psych in the involvement of the human being in the order of parenthood; Michel Tort and his criticism of the theories of that author; and Genevieve Delaisi de Parseval and her proposal of a broader definition of the family. And, finally, Sabine Prokhoris, and her distinction between "sexuation" and "difference of the sexes".

Deseja‑se, no entanto, alcançar no processo de formação, o perfil manifesto no ideário que norteia os princípios da integralidade, que enfatiza a importância da atenção primária. Apesar das mudanças curriculares experimentadas na formação superior em Fisioterapia, organizadas de forma integrada e apoiadas na interdisciplinaridade, percebe‑se que o conceito de integralidade não é reproduzido e incorporado de forma efetiva, desde o início da graduação até o momento do estágio prático na clínica/escola da Universidade. Objetivos: Verificar se as propostas presentes na concepção do cenário de ensino foram efetivadas de acordo com as premissas de integralidade de atenção à saúde. Métodos: Na tentativa de buscar respostas para tais questionamentos, foram analisados os documentos diretivos da instituição de ensino – Projeto de Desenvolvimento Institucional (PDI, Projeto Pedagógico Institucional (PPI e o documento Centro Integrado de Saúde (CIS –, para podermos verificar se tais documentos permitem a proposição de estratégias agregadoras da integralidade na atenção à saúde. Resultados e Conclusão: Tais documentos demonstraram uma sinergia com os princípios humanos fundamentais, para com o ser, para com o aluno e para com a sociedade como um todo, agindo assim, em consonância com os preceitos da integralidade.

Surge assim a definição de critérios de gestão da rega em que as dotações são “deficitárias”, isto é, em que se fornece à cultura uma quantidade de água inferior à correspondente à ETc calculada. Durante as campanhas de rega de 2004 e 2005 decorreram ensaios experimentais com “rega deficitária”, em parcelas regadas do Perímetro do Divor: em 2004 avaliou-se e caracterizou-se o comportamento da cultura do girassol, sujeita a diferentes regimes hídricos, com três cenários diferentes de decisão para definir a oportunidade e dotação de rega: 1 considerando como oportunidade de rega (ponto de rega o limite inferior de gestão (ou défice de gestão permissível, tradicionalmente definido por limite do rendimento óptimo (LRO na zona da reserva facilmente utilizável do solo; 2 e 3 considerando como oportunidade de rega (ponto de rega dois limites abaixo do LRO (10 e 30%, respectivamente; em 2005 avaliou-se e caracterizou-se o comportamento da cultura do milho, sujeita a três cenários de gestão da água de rega: 1 regime óptimo de fornecimento de água igual às necessidades hídricas da cultura, traduzidas pela ETc calculada; 2 nível 1 de “rega deficitária” regime de regas 10% abaixo do valor de ETc; 3 nível 2 de “rega deficitária” regime de regas 30% abaixo do valor de ETc.

    Full Text Available O Programa de Agentes Comunitários de Saúde (PACS foi introduzido no Brasil em 1991 como uma tática para o desenvolvimento de atividades relacionadas à prevenção de doenças e educação em saúde. Em 1994, o Ministério da Saúde propôs o Programa de Saúde da Família (PSF como estratégia de reestruturação da atenção à saúde. Essas propostas introduzem, no cenário da saúde, um novo ator, o Agente Comunitário de Saúde (ACS, desempenhando importante papel na atenção básica, ao agir como um elo entre famílias, usuários e serviço de saúde. O estudo toma como objeto o trabalho desenvolvido pelos ACS em uma unidade do PSF do município de Volta Redonda-RJ. Tem como objetivo discutir os aspectos facilitadores e limitantes das atividades designadas aos ACS. Trata-se de uma pesquisa do tipo descritiva, com abordagem qualitativa. A análise de dados se deu por categorias analíticas, que emergiram a partir dos dados encontrados nas entrevistas. Após a apreciação dos dados, pôde-se constatar que os ACS do PSF de Volta Redonda ainda não recebem formação destinada à execução de suas atividades e que consideram a experiência prática como o principal motor para o desempenho delas. O trabalho em equipe é reconhecido como espaço de circulação de saberes científicos e o saber popular como mediador entre a equipe e a população.

    Full Text Available A magnitude dos problemas socioambientais relacionados à urbanização, industrialização e esgotamento de recursos naturais tem impacto crescente sobre a saúde e o ambiente. Paradoxalmente, os padrões de consumo demandam a ampliação da produção industrial, baseada na exploração de recursos não renováveis, cujos riscos tecnológicos, particularmente os da indústria petroquímica, impõem dificuldades reais às medidas de controle e vigilância à saúde. O refino de petróleo é uma atividade potencialmente danosa ao ambiente e à saúde humana, particularmente aos trabalhadores. Esse estudo objetivou caracterizar os cenários de risco para a saúde ambiental decorrentes da instalação de uma refinaria de petróleo na Região Metropolitana de Recife (Pernambuco. Com base em dados secundários e referências da literatura, construiu-se uma matriz de reprodução social para contextualizar os problemas nas dimensões biológica, da consciência e conduta, econômica, política e ecológica, permitindo presumir riscos, com vista a subsidiar o desenvolvimento e a organização das ações de vigilância em saúde no Estado, articuladas intersetorialmente, com participação social, capazes de intervir sobre os riscos e evitar o adoecimento dos trabalhadores e da população nesse território.The magnitude of the environmental and social problems due to urbanization, industrialization and exhaustion of natural resources has shown an increase in the impact on health and environment.

Destarte, a GP não deve ter papel tradicional de suporte, mas, sim, constituir competência essencial organizacional, uma vez que os recursos humanos são responsáveis pela produção de conhecimento, constituindo uma fonte de vantagem competitiva, devendo ser valorizados e desenvolvidos por meio de políticas de GP. Assim, o objetivo precípuo deste trabalho foi apresentar o cenário dos estudos sobre políticas de gestão de pessoas, mostrando os resultados de uma revisão bibliográfica que abrange uma síntese do estado da arte e o cenário dos 108 estudos produzidos nacionalmente nos periódicos científicos de nível superior (maior/igual a Qualis B2 da área de Administração nos últimos dez anos, ou seja, no período compreendido entre 2000 e 2010. Tal revisão permitiu o delineamento de uma agenda de pesquisa. Os resultados engendrados de fato apontaram a relevância estratégica para as organizações dos estudos sobre políticas de gestão de pessoas; não obstante, destacou-se a premência de realizar mais estudos sobre o tema, uma vez que algumas políticas, embora estratégicas, ainda são bem pouco investigadas. Há lacunas na literatura também no que tange ao desenvolvimento e à validação de instrumentos e à realização de ensaios teóricos. Em síntese, sugere-se relacionar as políticas e práticas de GP a outras variáveis do comportamento organizacional e combinar diferentes perspectivas metodológicas para analisar com maior propriedade seus efeitos no bem-estar dos colaboradores e nos resultados organizacionais.

Privilegiou-se, como elemento de análise, a presença de novas mídias no mundo contemporâneo, as quais têm incidido significativamente na forma como alunos e alunas elaboram suas identidades e se relacionam com informações e saberes. Para tanto, perspectivas teóricas sociológicas, psicossociais e educacionais foram utilizadas, tecendo-se um cenário que apresenta dilemas e perspectivas na relação de jovens e adolescentes contemporâneos com as práticas de escolarização que ainda se presentificam nas escolas de ensino médio. Os autores concluem que a escolarização, nesta etapa do ensino, para ser efetivada, não poderá ignorar as novas configurações subjetivas desses sujeitos e as novas mídias utilizadas por eles, o que vem a gerar nova demanda educacional para atuais e futuros professores.In this paper, the authors inquire about the new forms of subjectivity engendered in the contemporary scene and which has had repercussions on the relationship of adolescents and young subjects with high school. As part of the analysis, we focused on the presence of new media in the contemporary world, which have focused significantly on how boys and girls develop their identity and relate to information and knowledge. To that end, sociological theoretical perspectives, psychosocial and educational needs were used, weaving a scenario that presents dilemmas and prospects for young people and teenagers with contemporary practices of schooling that are still present in high school. The authors conclude that for schooling, at this stage of education, to be effected, it cannot ignore the new subjective configurations of these subjects and the new media used by them, which generates new demands for education for

    Full Text Available Neste artigo se examina a não adequação dos EUA ao parecer da OMC no contencioso do algodão. Argumenta-se que tal atitude é irracional do ponto de vista do Estado unitário e racional, mas que pode ser explicada por meio de uma perspectiva fragmentada do Estado. Assim, embora a administração desejasse a adequação, cotonicultores e congressistas potencializados por instituições políticas constrangeram as mudanças necessárias. Ao final são projetados cenários para a modificação da política de subsídios agrícolas dos EUA.The article examines the non compliance of the United States with the WTO report on the cotton dispute. It is argued that that attitude is not rational from the unitary and rational State point of view, but it can be explained through a fragmented perspective of the State. Thus, although the administration desired to comply, cotton growers and congressists, strengthened by political institutions, constrained the needed changes. In the end, scenarios about possible changes in the U.S. agriculture subsidy policy are projected.

En este artículo revisaremos información contemporánea, abordando los diversos escenarios de educación para el manejo del pacientes con ICC.A insuficiência cardíaca congestiva (ICC apresenta, além da magnitude dos dados epidemiológicos, características relevantes, incluindo hospitalizações freqüentes devidas à exacerbação dos sinais e sintomas, que devem ser mais amplamente abordados para reduzir o impacto negativo da doença sobre o sistema público de saúde. Com o advento dos vários ensaios clínicos na área de ICC, o tratamento da doença passou a ser mais complexo, necessitando de uma estrutura organizada para o atendimento de pacientes por ela acometidos. A educação, nesse contexto, é considerada essencial para reduzir a morbimortalidade. O cenário, para o início ou a continuidade do processo educativo, pode ser hospitalar (internação, ambulatorial, domiciliar, hospital-dia ou, ainda, ser uma combinação desses ambientes. Os principais pesquisadores nessa área reconhecem e estimulam a investigação de outros caminhos, que melhorem os resultados no tratamento farmacológico e não-farmacológico.

Em sua base empírica, estão os dados primários advindos de uma pesquisa realizada com dirigentes e/ou fundadores de catorze associações voluntárias brasileiras identificadas por uma filosofia de ação comum. A discussão analisa a ação dessas associações e outras ações voluntárias também surgidas no cenário brasileiro da década de noventa do século XX. Destacamos como conclusão o fato de que às iniciativas voluntárias é preciso ancorar a perspectiva de um circuito de trocas, de proximidade e reciprocidade, às custas de recairmos em ações de benemerência, que reativam a filantropia e a dependência.The present article discusses the theme of volunteer associativism based on the theoretical foundation of the theory of donation (1960. In his empirical base are the primary data of a research carried out with leaders and/or founders of 14 Brazilian voluntary associations identified by a common action philosophy.

    Full Text Available O presente artigo busca situar a obra de Milton Erickson no cenário da transição de paradigmas científicos, particularmente da psicologia clínica. Destaca-se que as contribuições desse autor, ao mesmo tempo em que denunciam as limitações do paradigma dominante, apontam na direção de pressupostos distintos, muito afins com as perspectivas de um paradigma emergente. A metáfora do cavalo de Tróia busca retratar a influência sutil e intensa do trabalho desse autor sobre as perspectivas consagradas, de modo que, enquanto fascina e causa admiração, traz em si um potencial elevado de reflexão crítica e incisiva sobre essas mesmas perspectivas. Destacando três aspectos centrais desse processo - a impossibilidade teórica, o resgate da subjetividade complexa e a busca de novas racionalidades - o artigo é concluído delineando possíveis caminhos para a concepção e o uso do legado de Erickson.This article places Milton Erickson's work in the scenerio of transition of scientific paradigms, especially in clinical psychology. The text shows that Erickson' contribution denounces the limitations of the dominant paradigm and at the same time points to different assumptions that are very similar to the emergent paradigm's perspectives. The trojan horse metaphor aims at showing the powerful and subtle influence of Erickson's work on sacred perspectives. While Erickson's work cause fascination and wonder it simultaneously provoques critical and incisive reflections about the sacred perspectives. This paper makes salient three main aspects - the theorical impossibility, the rescue of a complex subjectivity and, at last, the search of new racionalities. As a conclusion, possible pathways for understanding and using Erickson's legacy in the field of clinical psychology are enphasized.

Para isto utilizam-se cinco modelos globais do IPCC AR4 (CCCMA, GFDL, HadCM3, MIROC e GISS, para o clima do século XX (1961-1990 - 20C3M e para o cenário futuro SRES_A2 (2011-2100. As características em comum que os modelos apresentaram (a exceção do MIROC para as três climatologias futuras (2011-2040, 2041-2070 e 2071-2100, principalmente, no verão e na primavera, foram o deslocamento da baixa continental (associada à baixa do Chaco para o sudoeste da sua posição climatológica (1961-1990, e da Alta da Bolívia para o noroeste. Além disso, os cinco modelos simularam, para o clima presente, uma Alta do Pacífico Sul (APS menos intensa em relação à Reanálise do NCEP, sugerindo menor subsidência sobre a sua região de atuação. Para cenários futuros os modelos GISS e HadCM3 simularam a APS menos intensa. Por outro lado, para a alta do Atlântico Sul, não existiu um consenso nos modelos. Em geral foi simulada mais intensa (a exceção do GISS, sobretudo no outono e no inverno. O modelo HadCM3 simulou a circulação de verão e primavera mais próxima à Reanálise, com uma ZCAS melhor definida, e uma área menor de anomalias negativas de chuva sobre a Amazônia, em relação aos outros modelos. Já para o cenário futuro este modelo modificou seu padrão de chuvas, e anomalias positivas, sobre a costa norte do Peru e Equador, e negativas sobre o Nordeste e leste da Amazônia, foram observadas, associadas a uma APS enfraquecida e deslocada para o sul, o que reforçou a ZCIT do Pacífico sobre 5ºS. Uma diminuição da convergência de umidade sobre a Amazônia também foi observada.In this paper changes in the atmospheric circulation that may occur in the South America (SA as a consequence of climate change were studied for

    2004-01-01

    Centaurus A, the nearest AGN shows molecular absorption in the millimeter and radio regime. By observing the absorption with VLBI, we try to constrain the distribution of the gas, in particular whether it resides in the circumnuclear region. Analysis of VLBA observations in four OH and two H2CO transitions is presented here, as well as molecular excitation models parameterized with distance from the AGN. We conclude that the gas is most likely associated with the tilted molecular ring structure observed before in molecular emission and IR continuum. The formaldehyde absorption shows small scale absorption which requires a different distribution than the hydroxyl.

O Programa de Saúde da Família (PSF coloca a família nas agendas das políticas sociais brasileiras em 1994, refletindo tanto interesses do modelo neoliberal como de forças sociais solidárias.Vê-se que tal inclusão gerou multiplicidade de abordagens tais como: família/indivíduo; família/domicílio; família/indivíduo/domicílio; família/comunidade; família/risco social; família/família. Essas abordagens, por não dialogarem entre si, acabam por compor um quadro insuficientemente identificado, dificultando a assistência.

    Full Text Available Simulações do clima presente foram realizadas no Hadley Center, Reino Unido para o período de 1960 a 1990 com o modelo atmosférico regional HadRM3P aninhado no modelo global HadAM3. Ambos os modelos foram integrados com temperatura da superfície do mar (TSM observada. Os resultados do HadRM3P, disponibilizados pelo CPTEC/INPE, foram investigados sobre o Estado da Bahia comparando-os com dados diários observados por uma rede de 29 estações meteorológicas do INMET. O modelo foi capaz de simular de forma acurada os principais padrões do ciclo sazonal de precipitação, temperatura e umidade relativa a 2 m em quase todo o Estado da Bahia. Entretanto, a magnitude da precipitação ao longo do litoral foi menor do que a observada, e o modelo não produziu nenhuma precipitação no semi-árido e oeste da Bahia durante os meses de junho-julho-agosto, impondo um cenário climático mais drástico que o observado. O HadRM3P foi também integrado aninhado no modelo acoplado oceano-terra-atmosfera HadCM3, recebendo a TSM prescrita produzida por esse modelo, para simular os cenários climáticos A2 e B2 do IPCC no período de 2070 a 2100. Essas simulações sobre o Estado da Bahia indicaram a redução da precipitação anual e o aumento da temperatura média do ar a 2 m em todo o Estado em relação à simulação do clima presente. O mesmo padrão de modificação da temperatura a 2 m e da precipitação foi produzido para os dois cenários, mas com maiores magnitudes para o A2. A maior redução de precipitação foi observada no litoral - cerca de 70% - e o maior aumento de temperatura foi no noroeste e norte - cerca de 5ºC.Simulations of the present climate were performed in the Hadley Center, UK, for the period 1960-1990 with the regional atmospheric model HadRM3P nested in the global model HadAM3 integrated with observed sea surface temperature (SST.

E.N. has garnered a reputation as an outstanding centre of research, training and education. Functioning as a task force within S.C.K. E.N., the international school for Radiological Protection (i.s.R.P.) initiates and manages training and research projects and contributes to related activities on national and international level. I.s.R.P. activities are situated on three axes: Coordination and organisation of training and education programmes on radiological protection The i.s.R.P. training activities deal with all aspects of radiological protection and are directed to the private, medical and industrial nuclear sector, national and international policy organisations, the political and academic world and the general public. Courses are also organised in cooperation with technical high schools, universities and public and private health services. In addition, i.s.R.P. is involved in international research networks and training programmes, such as those of the European Commission and the IAEA. The i.s.R.P. team of lecturers includes technicians, physicists, biologists, medical doctors, engineers and social scientists, who all bring insights and ideas from their specific background into the course programmes. As S.C.K. E.N. staff members, they have a solid knowledge and experience in their field, and can thus directly transfer their theoretical knowledge and practical experience to the various courses. Course programmes are composed together with the customer, drawing from the set of basic and expertise course modules and completed with technical visits. The basic modules textbooks exist in Dutch, French and English. In addition, all course modules and visits can be lectured and guided in Dutch, French or English. Research on trans-disciplinary aspects of education and training Understanding the benefits and risks of radioactivity requires technical insight and training, but also an understanding of the context and a sense for the social and philosophical aspects of the situation. In coordination with the academic sector, the research of i.s.R.P. concentrates on how to integrate this trans-disciplinary approach in education and training programmes for professionals as well as students and pupils. Policy support with regard to applied education and training on a national and international level The implementation of a coherent approach to education and training in radiological protection becomes crucial in a world of dynamic markets and increasing worker mobility.

    Full Text Available Os sistemas biológicos são governados pela soma de todos os genes expressos, proteínas, metabólitos e elementos de um organismo. A análise do ionoma de um tecido auxilia a identificar, entre outros aspectos, genes que contribuam para maior ou menor acúmulo de elementos essenciais e metais pesados, bem como a interação entre processos metabólicos. O conhecimento do ionoma, aliado ao uso de técnicas de biologia molecular, formam um sistema muito eficiente para mapeamento gênico, para estudos de genômica funcional e para caracterização geral do estado fisiológico das plantas em uma determinada condição. Além disso, o estudo do ionoma permite avaliar as interações existentes entre os mais diversos íons das plantas e como a disponibilidade de um íon afeta a absorção e uso de outros. O objetivo desta revisão é apresentar e discutir o ionoma como uma ferramenta importante na elucidação dos mais diversos mecanismos envolvidos na absorção, translocação e acúmulo de elementos essenciais e não-essenciais em plantas e sua relação com o metabolismo delas.Biological systems are governed by the sum of all expressed genes, proteins, metabolites and components of an organism. The analysis of a tissue ionome helps to identify, among others, genes that contribute to a greater or lesser accumulation of essential elements and heavy metals, as well as interaction between metabolic processes. The ionome knowledge, coupled with the use of molecular biology techniques, form a very efficient system for gene mapping, and functional genomic studies, and general characterization of plants physiological status in a given condition. Another interesting process that the ionome study allows to analyse is the interactions among plants' ions and how such ion availability can affect the absorption and use of others. The aim of this review is to present and discuss the ionome as an important tool in the elucidation of several mechanisms involved in absorption, translocation and accumulation of essential and nonessential elements in plant and its relation with their metabolism.

    In 2015, we initiated a survey of Scorpius-Centaurus A-F stars that are predicted to host warm-inner and cold-outer belts of debris similar to the case of the system HR~8799. The survey aims to resolve the disks and detect planets responsible for the disk morphology. In this paper, we study the F-type star HIP~67497 and present a first-order modelisation of the disk in order to derive its main properties. We used the near-infrared integral field spectrograph (IFS) and dual-band imager IRDIS of VLT/SPHERE to obtain angular-differential imaging observations of the circumstellar environnement of HIP~67497. We removed the stellar halo with PCA and TLOCI algorithms. We modeled the disk emission with the GRaTeR code. We resolve a ring-like structure that extends up to $\\sim$450 mas ($\\sim$50 au) from the star in the IRDIS and IFS data.

    Context: We study the structure and evolution of circumstellar discs around evolved binaries and their impact on the evolution of the central system. Aims: To study in detail the binary nature of RUCen and ACHer, as well as the structure and mineralogy of the circumstellar environment. Methods: We combine multi-wavelength observations with a 2D radiative transfer study. Our radial velocity program studies the central stars, while our Spitzer spectra and broad-band SEDs are used to constrain mineralogy, grain sizes and physical structure of the circumstellar environment. Results: We determine the orbital elements of RUCen showing that the orbit is highly eccentric with a rather long period of 1500 days. The infrared spectra of both objects are very similar and the spectral dust features are dominated by Mg-rich crystalline silicates. The small peak-to-continuum ratios are interpreted as being due to large grains. Our model contains two components with a cold midplain dominated by large grains, and the near- an...

    Full Text Available Social Psychology in Brazil has been showing a progressive scientific growth since the 1970's. Such development justifies the current interest in performing an evaluation of scientific contributions of Brazilian Social Psychologists within the international context. In this respect, a literature review allowed the identification of 10 evaluative models in Social Psychology. Such models are applied to the psychological and sociological currents in Social Psychology, which are the most prominent internationaly. Even though such evaluative models are well designed, they present limitations with regard to their spectrum of application within Social Psychology. Thus a 5 - dimensional conceptual model has been developed: Philosophical assumptions; Research subject; Research methods and techniques; Conceptual matrix; Applications. Main results of the literature review were obtained from this 5 - dimensional model.A Psicologia Social no Brasil vem apresentando uma crescente maturidade científica desde a década de 1970. Esse desenvolvimento justifica o atual interesse em proceder a uma avaliação das contribuições científicas de psicólogos sociais brasileiros numa perspectiva internacional. Nesse sentido, foi conduzido um estudo bibliográfico, que possibilitou a identificação de 10 modelos de avaliação da Psicologia Social. Esses modelos são aplicados às vertentes psicológica e sociológica da Psicologia Social, que são as que mais se destacam no plano internacional. Embora esses modelos avaliativos estejam tecnicamente bem fundamentados, apresentam limitações quanto à abrangência do objeto a avaliar, que é a Psicologia Social. Assim, propõe-se um modelo baseado em cinco dimensões: pressupostos filosóficos; objeto de investigação; métodos e técnicas de pesquisa; matriz conceitual; e, aplicações. Os principais resultados deste estudo bibliográfico foram obtidos mediante a aplicação do modelo dessas cinco dimensões básicas.

    Full Text Available Abstract Taking the “principles of historical phonology” – formulated in the 30s by Jakobson – as a starting point, my aim in this article is to show that the traditional “life-cycle” model of creole grammar formation is not the best one. It presupposes the problematic concepts of pidgin and nativization. I show that a better alternative would be to consider that creole grammar is formed when the mixed medium of interethnic communication resulting from the contact of mutually unintelligible languages becomes the primary language of the emerging community. Therefore, communalization is more important than nativization. Additionally, I show that the processes which occur in creole formation are very common elsewhere.  .

    2002-01-01

    The impact of habitat fragmentation and isolation on the genetic diversity of populations has attracted much attention in studies of meta-population and conservation biology. In this work, using the randomly amplified polymorphic DNA (RAPD) technique, we studied the genetic diversity of central, peripheral and peninsular populations of ratlike hamster, which were collected in five locations of the North China Plain and its surrounding areas, in 1999. The study revealed that, ⅰ) the genetic diversity of central population of Raoyang County>the sub-central populations of Gu'an County and Taikang County>the peripheral population of Shunyi District>the peninsular population of Mentougou District; ⅱ) the genetic diversities of the five populations were positively correlated to the nearest distances to the peripheral line of population distribution; ⅲ) there were significant differences of gene frequencies of some RAPD fragments among the five populations. More RAPD fragments disappeared in peripheral populations than in central or sub-central populations. The frequencies of two RAPD fragments were correlated to the latitude. This study clearly indicated that the variation of the genetic diversities of the five populations was caused by edge effect and frag- mentation through the enhanced inbreeding and genetic drift, and thus supported the view that habitat fragmentation and related edge effect reduce the population genetic diversity.

Trata-se de saber em que medida essas relações hoje se afastam do modelo de "associação prática" em direção a um modelo, normativamente mais exigente, de "associação de objetivos".Despite the lack of a common legitimate authority the international relations after Westphalia share enough elements of order for being characterized as a form of "practical association": (equal national sovereignty, diplomacy, international law and the balance of power. The fit-ness of those pilars of the post-Westphalian world order for thinking the international relations after the Cold War is discussed. It is asked how far those relations are leaving the model of a practical association towards another normatively more demanding model, of "goals association".

  7. Cenários criminosos e pecaminosos nos livros de ocorrência de uma escola pública

    2002-01-01

    Full Text Available The text identifies relations between the theme of confession and the narration extant in the recent registers of occurrences of a public school in Curitiba, based on post-structuralist analytical references. These registers relate cases of students considered by the school as problematic and undisciplined and contain 517 occurrences for the years 1998 and 1999. In the records of the registers, we focus on elements that produce criminal and sinful scenarios in daily school life, with regard to that which they may express in terms of confessional practices of a juridical and religious type. From the juridical point of view, confession is seen in some of its possible articulations with other elements present in the narrative of the registers, like evidence, proof, clues, making part of a kind of daily miniinquiry of the school, and in so doing producing accusations, crimes and punishment. From the religious point of view, the confessional dynamic is seen through these registers as a part of the process of "circulation of sins", in which the traditional battle between Good and Evil, between God and the Devil, is presented and, in a certain way, taught.

  10. The use of single-specimen techniques for measuring upper shelf toughness properties under impact loading rates. Convention TRACTEBEL/SCK-CEN 2005 Task 1.1.5

    International Nuclear Information System (INIS)

    The multiple-specimen method (low-blow or stop-block tests) is the conventional approach for measuring the upper shelf fracture toughness of metallic materials under impact loading rates, typically fatigue precracked Charpy specimens tested on an instrumented pendulum machine. The method is fairly simple but requires a relatively large number of specimens. Nowadays, several single-specimen methods are available, which are purely based on the analysis of the instrumented force/displacement trace; they don't need any dedicated instrumentation for the measurement of crack extension during the test. Three of these techniques have been applied in this work to low-blow tests performed at different temperatures on two significantly different RPV steels (20MnMoNi55 and JSPS): the Normalization Data Reduction (NDR) technique, Schindler's Analytical 3-Parameter Approach and Chaouadi's method. Analyses have been performed after applying a double fitting approach to the raw test data, which allows selecting a limited set of force/displacement data which are representative of the whole instrumented trace. Results show that all three methods provide acceptable accuracy in terms of both ductile crack initiation and resistance to crack propagation (tearing modulus). However, for this type of analysis we recommend the use of the more widely accepted NDR technique, which is described in detail in the ASTM E1820-01 standard (although the limitations on data smoothness presently enforced in the standard seem incompatible with the oscillations of a typical dynamic PCCv curve).

    Full Text Available O presente artigo tem por propósito mostrar como a competição política em âmbito municipal foi afetada pelo impacto do novo arranjo federativo brasileiro pós-1988 e pela introdução do sistema multipartidário. A análise comparada de mais de 400 municípios detectou importantes alterações no processo de competição eleitoral e partidária nas disputas municipais: houve modificações no padrão descrito pela literatura que se dedica a estudar o fenômeno do poder local. A tese central, presente na literatura municipalista, declarava que a causa da “oligarquização” dos subsistemas partidários locais era a centralização de recursos e decisões no Executivo Federal. A alteração das regras objetivando descentralizar as competências e funções provocou um realinhamento das disputas eleitorais e políticas nos contextos tidos como oligárquicos[1].

    2013-09-01

    Full Text Available Resumo: Reconhecida por seu trabalho como crítica literária, Lúcia Miguel Pereira é pouco conhecida como romancista. O presente estudo tem o propósito de ‘apresentar’, de modo sucinto, as três narrativas de ficção Maria Luísa, Em Surdina e Amanhecer publicadas na década de 30 tendo em vista a vinculação da ficção aos acontecimentos daqueles tempos e, sobretudo, ao espírito ideológico predominante naquele contexto. Se a crítica literária contemporânea dos anos 30 reconheceu, na literatura nacional desse período, duas vertentes de escrita, a literatura social ou proletária e a literatura intimista ou psicológica, este estudo pretende ainda discutir a observação de Jorge Amado que acusa a autora de produzir romance engajado, subordinando conscientemente a criação a uma doutrina. Frente a esse apontamento do escritor baiano, notamos que, mais relevante que a vinculação da autora ao pensamento de direita ou de esquerda é o trabalho de representação de aspectos muito sutis da condição política e social daqueles tempos que foram ‘recriados’ pela autora, e transformados em elementos internos conduzindo a trajetória das personagens, principalmente femininas, e configurando, dessa forma, a razão de ser, sobretudo da obra Em Surdina. Se, para Jorge Amado, esses aspectos impediram o desenvolvimento da narrativa, a nosso ver, eles revelaram inquietações, anseios e temores femininos que integraram tanto a ficção quanto a crítica de Lúcia Miguel Pereira, dando forma assim a uma escrita intimista bastante coerente com o discurso predominante. Sendo assim, por vezes, a leitura dos relatos de ficção conduzem a uma revisão da subjetividade da autora associando-a àquelas subjetividades construídas em suas ‘criaturas de papel’.Palavras-chave: Ficção; história; crítica; década de 30; mulher. Abstract: Recognized for her work as a literary reviewer, Lucia Miguel Pereira is little known as a novelist. The present study aims to ‘present’, succinctly, the three fiction narratives Maria Luísa, Em Surdina e Amanhecer, published in the 30s, in order to link the fiction to the events of those times, especially, to the ideological spirit prevailing in that context. If the contemporary literary criticism of the 30s recognized, in the national literature of that period, two lines of writing, that is, the social or proletarian literature and the intimate or psychological literature, this study also intends to discuss Jorge Amado’s observation which accuses the author of producing novels inspired by personal interests, thus consciously subordinating the creation to a doctrine. Considering that remark by the writer from Bahia, we note that more relevant than the author’s bond to conservative or liberal thought is her effort of depicting very subtle aspects of political and social condition of those times which have been ‘recreated’ by her and changed into internal elements, leading the characters’ path, especially the female characters, and, therefore, setting the reason for being, mainly in the work Em Surdina. If, for Jorge Amado, those aspects have hindered the narrative’s development, in our view, they have revealed concerns, anxieties and women’s fears, which had made part of Lucia Miguel Pereira’s work, both in the fiction and in textual criticism, thus shaping an intimate written style quite consistent with the prevailing discourse. So, at times, the reading of the fiction narratives lead to a revision of the author’s subjectivity, by associating it to those subjectivities which have been framed in her “paper creatures”.Keywords: Fiction; history; criticism; decade of 30; woman.

    Full Text Available Partindo da constatação de que a moral é um dos mais discutidos e polêmicos temas da sociedade contemporânea, o autor observa uma relação entre a visibilidade do debate moral e a gravidade das práticas imorais. Na tentativa de encontrar caminhos que conduzam à mudança dessa realidade, desenvolve o argumento de que os problemas morais não se restringem apenas ao comportamento desse ou daquele grupo social, desse ou daquele indivíduo, mas que eles se encontram intrinsecamente relacionados às tradições, aos costumes e aos valores que constituem o ethos histórico-cultural da sociedade. Por isso, entende que a superação da barbárie moral não pode ser alcançada mediante intervenções e sanções tópicas, locais, superficiais, mas que é necessário um repensar amplo e corajoso dos arquétipos de nossa cultura no que se refere aos conceitos de cidadania, democracia, justiça social e espaço público. O autor defende a tese de que a educação moral, para além da tradicional disciplinarização, deve centrar-se na formação dialógica do sujeito moral, tendo como escopo a virtude da justiça.From the statement of fact that moral is one of the most discussed and polemical topics in our contemporaneous society, the author observes a relationship between the visibility of the moral debate and the seriousness of immoral practices. In an attempt to find paths that lead to change this reality, he develops the argument that the moral problems are not restricted to the behavior this or that social group or individual, but that they are intrinsically related to the traditions, customs and values that constitute the historical-cultural ethos of society. He thus understands that moral barbarism cannot be overcome through interventions and topical, local or superficial sanctions, but that we need rethinking widely and courageously the archetypes of our culture in what regards the concepts of citizenship, democracy, social justice and public space. The author advocates the thesis that, beyond the traditional disciplinarization, moral education must focus on the dialogical training of the subject's moral, with the virtue of justice in our scope.

    2015-10-01

    Full Text Available This paper presents an embryonic exercise for building up relationships between information design and the city. It starts from the principle that information design is an important mediator for the use of urban environments and that the city, as a technical informational media, has its use boosted from its environmental assets. The article is based on important studies on the city that question current urban uses. Thus, besides the basics of information design, the article takes into account authors who discuss the city, like Lucrecia D’Aléssio Ferrara and David Harvey, or space, technique and policies like Maldonado and Agamben, as well as Norman’s affordance theory as potential contributions to the relationship between information design and context. An initial look, derived from a pedagogical teaching experience in the classroom, is proposed. The objective is to demonstrate how since the beginning of an undergraduate course it is possible to think about design development from context and relationships.

  16. Lasers in odontology: survey of work carried out in the laboratories of the CEN/Saclay Service of Advanced techniques and Physical Chemistry

    International Nuclear Information System (INIS)

    After carbon dioxide laser treatment the mineralised dental tissues (enamel, dentine) of humans and animals were examined by photon microscopy and subjected to Vickers microdurometric tests. They show a melted zone and a heat-affected zone which are compared with synthetic hydroxyapatite. The plates illustrate the resulting structural changes, micro-hardness increase and resistance to acid attack. The thermal diffusiveness of these tissues being slight, the heat-affected zone is not very deep under pulsed conditions. For a surface temperature of 2000C on the dental enamel the thermal gradient is 10-40C m-1 over a layer of 1 mm for a 1-second pulse duration. Bacterial cultures have demonstrated the sterilising effect of the laser. This laboratory research has so far given rise to 1200 clinical treatments on humans

    2009-01-01

    Polars (or AM Her systems) are cataclysmic variables without a disc due to the strong magnetic field of the white dwarf. Most of their emission comes from the region where the accretion column impacts the white dwarf and cools through cyclotron and bremsstrahlung processes. We present a new code, CYCLOPS, to model the optical emission from these systems including the four Stokes parameters. It considers a three-dimensional region with the electronic density and temperature varying following a \\textit{shock-like} profile and a dipolar magnetic field. The radiative transfer is solved in steps considering the solution with non-null input radiation. The footprint of the column in the white-dwarf surface is determined by the threading region in the equatorial plane, i.e., the region from where the flow follows the magnetic lines. The extinction caused by Thomson scattering above the emitting region is optionally included. The fittings of observational data are done using a hybrid approach: a genetic algorithm is u...

    Full Text Available The introduction of international guidelines on Good Clinical Practices (GCP in 1996, immediately followed by the publication of Resolution CNS 196/96 in Brazil, created a great opportunity for Brazilian research centers to participate in international trials. Such studies must be strictly monitored in order to assure compliance with the regulations, as well as with the standards of patient safety. Clear agreement among the investigator, the sponsor and the institution carrying out the study must be previously defined in order to avoid any conflicts of interest during or after the study. Operational aspects, such as the time needed to gain regulatory approval of the study design, strategies for patient recruitment/retention and appropriate logistics, are also important. In 2005, the Brazilian National Clinical Research Network was established, bringing together a number of research centers in teaching hospitals. The objective was to subsidize public clinical research with state-of-the-art practices and appropriate technical/scientific training programs. The development of research protocols that prioritize public health care needs in Brazil is other fundamental goal of this network. This article addresses general aspects of clinical research, as well as some specific issues in psychiatry. Improving the health and quality of life of the global population is certainly the major objective of all of the work done in this area.A introdução de diretrizes internacionais de Boas Práticas Clínicas, em 1996, imediatamente seguida pela publicação da Resolução do Conselho Nacional de Saúde 196/96, abriu uma grande oportunidade para a participação de centros de pesquisa brasileiros em estudos internacionais. Tais estudos devem ser estritamente monitorados, a fim de assegurar a adesão às legislações, assim como garantir a segurança dos pacientes envolvidos. A fim de evitar possíveis conflitos de interesse durante e após o estudo, todos os aspectos relacionados devem ser claramente definidos previamente entre o pesquisador, o patrocinador e a instituição. Aspectos operacionais, tais como tempo para aprovação regulatória do estudo, métodos de recrutamento e retenção de pacientes e a logística em geral, também são importantes. Em 2005, a Rede Nacional de Pesquisa Clínica foi criada no Brasil, somando a experiência de vários centros de pesquisa ligados a hospitais de ensino. Seu objetivo é reforçar a atividade de pesquisa clínica no país, com práticas atualizadas e adequado treinamento técnico-científico. O desenvolvimento de protocolos de pesquisa que foquem as prioridades de saúde do país é outro objetivo fundamental da Rede. Aspectos gerais da pesquisa clínica e algumas particularidades em Psiquiatria são discutidos no artigo. O objetivo final de todo o trabalho nesta área de pesquisa é, sem dúvida, a busca de melhores condições de saúde e qualidade de vida da população.

Falhas na previsão de demanda causaram escassez de produtos nos pontos de venda, desgastes no relacionamento da empresa com seus revendedores, dificuldades nas unidades de produção e também perda de participação de mercado da DELTA e da vice-líder GAMA para marcas alternativas. A natureza dos problemas levantados sugere questionamentos que envolvem a estrutura da indústria e a constituição da arena do mercado, bem como decisões de governança, gestão e gerência envolvidas na configuração do próprio negócio. Construída a partir de dados coletados por meio de pesquisa bibliográfica, investigação documental e técnicas de observação direta, a narrativa se desdobra a partir das idéias de incerteza, transformação organizacional e integração, proporcionando possibilidades de aproveitamento do caso em disciplinas de Estratégia, Marketing, Produção e Ética, preferencialmente em cursos de graduação ou em matérias básicas de programas de pós-graduação.This case was based on the problems facing the Delta, a leader in the Brazilian urban pest control, from the dengue epidemic in the summer of 2007/2008, while sales of insecticides and repellants by industry players reached volumes significantly higher than expectations. Failures in forecasting demand caused shortages of products to sell, wear the company's relationship with its dealers, difficulties in production and also loss of market share from DELTA and GAMMA deputy leader for alternative brands. The nature of the problems suggests questions involving the structure of industry and the establishment of the marketing arena, as well as decisions on governance, administration and management involved in setting up own business. Constructed from data collected through literature review, desk research and direct observation techniques, the narrative unfolds from the ideas of uncertainty, organizational transformation and integration by providing opportunities for exploiting the case in disciplines of Strategy, Marketing, Production and Ethics, preferably at the graduate level or raw materials of post-graduation.

    Full Text Available ResumoMesmo após a publicação da Lei 8213, em 1991, que institui cotas para contratação de pessoas com deficiência, a inclusão delas no trabalho ainda é um desafio para a sociedade brasileira. Para tentar entender as principais barreiras que impedem este processo foi realizada uma pesquisa qualitativa no município de Belo Horizonte. Este estudo contou com entrevistas com atores importantes no processo de inclusão; e grupos focais com pessoas com deficiência e seus familiares. As principais barreiras encontradas foram: preconceito e discriminação; a relação familiar; o Benefício da Prestação Continuada; a baixa qualificação das pessoas com deficiência; a falta de acessibilidade; e o despreparo das empresas. Conclui-se que a elaboração de leis não é suficiente para a inclusão no mercado de trabalho e que os governos devem implementar políticas públicas que auxiliem este processo.

    Full Text Available ABSTRACT: Thirty five patient with unstable fractures of the lower thoracic and lumbar spine managed uniformly with Hartshill fixation and subla minar wiring were analyzed. On admission, 18 patients had complete neurologic deficit and 17 had incomplete lesions. The neurologic recovery and functional activities were assessed after an averag e follow up for 20.4 months. Improvement of neural function was seen in 71 % patients. Positive correlation was found between the level of injury and Frankel grades. The cord lesions tended to demo nstrate more severe neurologic deficit than cauda equina lesions. A component of dislocation to the injury also resulted in a more severe neural deficit. The complications were minor. Stable fixat ion of thoracolumbar spine fractures was helpful in decreasing hospital stay and recumbency period, the reby facilitating early rehabilitation of the spine injured patients.

    Full Text Available The field of mechanical engineering production is very important for many industries. Companies seek to improve their processes, methods, philosophies, mechanisms and technologies to achieve a competitive edge, win over consumer preference, and gain a greater share of a strained market. The aim of this paper is to carry out a behavioral analysis of demand for a company in the automotive sector by simulating a scenario that entails implementing an expansion of visibility of the steps of the manufacturing process, transit and storage. The methodology involves an extensive review of several cases, where the simulation tool is used to provide visibility of the different stages of production. It is expected to show that linear demand can equalize the level of stock when allied to the application of a marketing policy model of product and service demand along with the expansion of its dealer network’s visibility, allowing the placement of orders at any stage of the chain of production.

    Full Text Available O artigo trata da construção recente de novos diagnósticos médicos e de um correspondente mercado consumidor em potencial considerando o caso do distúrbio androgênico do envelhecimento masculino ou andropausa, "doença" que afetaria os homens a partir dos 35-40 anos de idade. A perspectiva utilizada centra-se nos estudos sociais da ciência e gênero e particularmente na necessidade de investigar as redes criadas no processo de construção dessa nova categoria. Por meio da análise da produção científica e da trajetória da construção da andropausa como fenômeno de interesse público, elabora-se um processo inédito de medicalização do homem e da sexualidade masculina, via o reforço na centralidade dos hormônios como modelo preponderante de entendimento corporal. Além disso, destaca-se a promoção de uma intrincada conexão simbólica que associa juventude, saúde, beleza e atividade sexual nos processos de patologização das fases ou de condições de vida e na recusa do envelhecimento.The article deals with the recent construction of new medical diagnoses and a corresponding potential consumer market by considering the case of Androgen Disorders of the Male Aging, or Andropause, "disease" that supposedly affected men from 35-40 years old. The approach used focuses on the social studies of science and gender and in particular the need to investigate the networks created in the process of the construction of this new category. Through the analysis of scientifi c production and the trajectory of construction of Andropause as a phenomenon of public interest, an unprecedented process of medicalization of men and male sexuality is enacted, by strengthening the centrality of hormones as predominant model for understanding the body. Moreover, there is the promotion of an intricate symbolic connection that links youth, health, beauty and sexual activity in the pathologization of the phases or conditions of life and the refusal of aging.

A ideia principal defendida é a de que políticas de QVT adotadas em empresas podem aliviar momentaneamente alguns sintomas, mas não ferem as causas estruturais dos problemas.

  9. A legal analysis of the use of ionising radiation in medical hospital practice: an inquiry into the influence of prevention and precaution on health protection and liability. Doctoral thesis prepared at SCK-CEN and defended in 2004

    International Nuclear Information System (INIS)

    The article refers to an abstract of a doctoral thesis. From a legal perspective there exists a clear need for a general framework describing conditions and consequences of risk management in the field of high technology. Despite the existence of many kinds of Safety Procedures and Soft Law, specific guidelines are lacking for regulators and courts, especially in case of scientific controversy and uncertainty about the health effects of an activity or a product such as low doses of ionising radiation, electro-magnetic fields, genetically modified organisms, PCB's in salmon etc. The research of the PISA Project on Legal Aspects and Liability has been focussed on the medical applications of ionising radiation. The safety approach depends on the risk characterisation and differs for stochastic and deterministic effects. The most important objective was to find liability or funding systems which can cope with these differences, in particular between dose limits (as for the nuclear industry), reference dose levels foreseen in the EC medical Directive (as for nuclear medicine), and Optimisation referring to the ALARA principle. Risk assessment and risk management that are based on traditional narrow risk-assessment models have to be revised in the light of the Precautionary Principle. This principle urges policy-makers to adopt a broader, more pluralistic approach, considering the societal equilibrium, i.e. the general interest of the activity at stake, the general impact of individual protective measures and the existence of reasonable alternatives from a sociological, economical, scientific and technological point of view. One of the characteristics of the Precautionary Principle relates to our opinion to the collective damage to human health, i.e. a detriment that relates to a group of people. Nevertheless, as a result of the application of the Precautionary Principle, we believe that in case of individual damage the standard of care shall be more and more defined, following the risk characterisation and assessment which has to be introduced once a scientific or societal problem occurs with regard to medical practices, already subject to the legal duty of Justification and of Informed Consent. For some specific cases, as paediatric CT doses, the 2003 report of the Belgian Health Council gives a clear warning and refers to collective doses that are significantly higher than in the neighbouring countries. It cannot be denied that such a repeated warning urges decision makers and hospitals to take corrective actions, in particular when poor optimisation is put in place. Causality in the nuclear field is another complex problem, where worldwide alternatives are under consideration, such as probability of causation. However, such a concept, based on statistical proof, can hardly be implemented in Belgian law since our tort- and insurance-system is based on the individual relationship between liable actor and victim

    In the molecule of the the title compound, [Fe(C5H5)(C28H22F6N2PS)], the absolute configuration is R C ,SFe . The dihedral angle between the trifluoro-methyl-substituted phenyl ring and the thio-urea plane is 41.8 (9)°. The iron atom is bound to the cyclo-penta-dienyl rings in the typical η(5)-manner in a close to eclipsed conformation. The crystal structure features N-H⋯S hydrogen bonds, with the S atom as an acceptor for both N-H groups, forming a layered arrangement parallel to (1-10). The two -CF3 groups are each disordered over two positions with refined occupancy rates for the major components of 0.66 (7) and 0.55 (5). The crystal was grown from mixed solvents (n-hexane and ethyl acetate). These solvents are disordered in the crystal and the resulting electron density was found to be uninterpretable. The solvent contribution to the structure factors was taken into account by back-Fourier transformation of all density found in the disordered solvent area using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. The formula mass and density do not take account of the solvent. PMID:23723760

Se trata de un estudio documental, con una muestra de 43 artículos. Los datos se analizaron con el uso de análisis de contenido. El análisis epistemológico mostró una preferencia por los temas relacionados con la contabilidad de los usuarios externos y los mercados de capitales, lo que favorece el uso de datos secundarios, a través de la investigación documental. Se observó la presencia unánime de estudios positivistas y uso de modelos econométricos para explicar la realidad observó sin ninguna teoría para apoyar estos modelos. Por lo tanto, se concluyó que el campo científico contable permanece sin cambios teóricos debido a productivismo que llevaron a la creación de una especie de "forma ideal" de legitimado, institucionalizada y difícil de modificar.

    The teak (Tectona grandis L. f. wood properties direct an intense process of domestication and plantation outside its original habitat. The interest in the species as an alternative for the traditional forest plantations in Brazil is growing. This review contributes with the recovery of technical and scientific information regarding teak aiming the subsequent proposition of a genetic breeding program. In this paper it is presented a brief review of the silvicultural methods for the species in Brazil. The positive perspectives and the main risks related to the teak plantation were explored. In  general, in the most recent genetic improvement  programs the employment of clones was a common strategy. The initial emphasis of the improvement programs were the growth rate and wood property (generally density. As for other species the proper choice of the selection methods resides in observing the genetic variances (additive and non-additive, herdability (broad and narrow, and the genetic correlations among characters. As in other forest  breeding programs the conversion of progeny tests in seedling seed orchards is common for a faster seed production and development of commercial clones
    or clonal seed orchards.

Neste documento, é apresentada uma breve revisão sobre os métodos silviculturais para a espécie no Brasil. Foram explorados aspectos positivos inerentes ao cultivo assim como os principais riscos. De forma geral, verificou-se que os programas recentes de  melhoramento genético concentraram-se no  desenvolvimento de clones. A ênfase inicial dos programas de melhoramento tem sido a taxa de crescimento e propriedades da madeira (geralmente densidade. Para a aplicação e escolha dos métodos de seleção em teca são importantes as variâncias genéticas aditivas e não aditivas, as herdabilidades no sentido restrito e amplo, e as correlações genéticas entre caracteres. Como em outros programas de melhoramento florestal, é comum a conversão de testes de progênies em pomares de sementes para a produção mais rápida de clones comerciais ou de pomares clonais de sementes.

    Full Text Available O artigo aborda a temática do financiamento e o processo de descentralização tendo como objetivo examinar a composição, a direção e a gestão dos recursos na área da saúde. A amostra investigada foi constituída por 14 municípios do Estado do Rio Grande do Norte. A pesquisa envolveu coleta de dados referente às transferências, recursos próprios municipais e gastos com atenção básica. Na análise da gestão foi realizado um levantamento junto aos dirigentes locais e conselheiros. Observa-se que o financiamento do Sistema Único de Saúde se faz às expensas das transferências federais e receitas municipais, com pequena participação dos recursos estaduais. A direção dos gastos tem privilegiado a atenção básica. No processo de gestão, verifica-se centralização das ações nas prefeituras. As secretarias municipais e os conselhos cumprem em parte a legislação e apresentam dificuldades na autonomia e o controle social. Os resultados mostram que os instrumentos de planejamento e gestão são limitados em função das contradições presentes no contexto institucional, político e cultural no âmbito regional.This article investigates the issue of funding and the decentralization process in order to examine the composition, application and management of resources in the healthcare area. The sample surveyed involved 14 municipalities in the state of Rio Grande do Norte, Brazil. The research involved data gathering of financial transfers, the municipality's own resources and primary healthcare expenses. Management analysis included a survey of local managers and counselors. It was seen that the Unified Health System is funded mainly by federal transfers and municipal revenues and to a far lesser extent by state resources. Funds have been applied predominantly in primary healthcare. The management process saw centralization of actions in the city governments. Municipal secretarial offices and councils comply partially with legislation, though they have problems with autonomy and social control. The results show that planning and management instruments are limited, due to the contradictions inherent to the institutional, political and cultural context of the region.

Methods:518 ultrasound examinations in 359 singleton pregnant women with accurately established gestational age was chosen in this prospective study to ex-plore the associations between gestational age and distal femoral second ossification center ( DF-SOC),proximal tibial second ossification center (PTSOC) and placental grading. In addition, 184 women performed ultrasound in one week before birth with complete data,were divided into RDS group (15 cases) and non-RDS group (169 cases). The rates of visibilities about DF-SOC ,PTSOC and placental grading were compared between two groups. Logistic regression anal-ysis was used to explore the relationship between the development of RDS and DFSOC,PTSOC or placental grading. Results:(1) Fetal DFSOC,PTSOC and placental grading were positively correlated with gestational weeks (spearman coefficient 0. 831,0. 716 and 0. 859,respectively, P0 . 05 ) . Conclusion:Fetal DFSOC,PTSOC and placental grading can be useful in estimating some spe-cific and critical gestational age,but may not be reliable markers to assess fetal lung maturity.

  6. Binding of Euplotes octocarinatus centrin with target peptide melittin

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Interactions between model target peptide melittin (ME) and Euplotes octocarinatus centrin (EoCen) were investigated by fluorescence spectra, circular dichroism (CD) spectra and native polyacrylamide gel electrophoresis (PAGE). In 0.1 mol/L N-2-hydroxyethylpiperazine-N-2-ethanesulfonic acid (Hepes) and 150 mmol/L NaCl at pH 7.4, EoCen and isolated short C-terminal domain of EoCen (SC-EoCen) form 1:1 peptide:protein complexes. However, no detectable signal changes can be observed while isolated N-terminal domain of EoCen (N-EoCen) or isolated long C-terminal domain of EoCen (LC-EoCen) was added into solution of ME. The interaction between EoCen and ME is specified exclusively for the short C-terminal domain of EoCen. On the basis of fluorescence titration curves, the conditional binding constants of ME with EoCen and SC-EoCen were calculated to be logKME-EoCen = 6.81±0.33 and logKME-SC-EoCen = 6.51±0.45, respectively.

  12. Influence of food components on lipid metabolism: scenarios and perspective on the control and prevention of dyslipidemias Influência de componentes dos alimentos no metabolismo lipídico: cenários e perspectiva no controle e prevenção de dislipidemias

    Full Text Available Cardiovascular diseases (CVD are the main causes of death in the Western world. Among the risk factors that are modifiable by diet, for reducing cardiovascular disease risks, the total plasma concentrations of cholesterol, triglycerides, LDL-C, and HDL-C are the most important. Dietary measures can balance these components of the lipid profile thus reducing the risk of cardiovascular diseases. The main food components that affect the lipid profile and can be modified by diet are the saturated and trans fats, unsaturated fats, cholesterol, phytosterols, plant protein, and soluble fiber. A wealth of evidence suggests that saturated and trans fats and cholesterol in the diet raise the total plasma cholesterol and LDL-C. Trans fats also reduce HDL-C, an important lipoprotein for mediating the reverse cholesterol transport. On the other hand, phytosterols, plant proteins, isoflavones, and soluble fiber are protective diet factors against cardiovascular diseases by modulating plasma lipoprotein levels. These food components at certain concentrations are able to reduce the total cholesterol, TG, and LDL-C and raise the plasma levels of HDL-C. Therefore, diet is an important tool for the prevention and control of cardiovascular diseases, and should be taken into account as a whole, i.e., not only the food components that modulate plasma concentrations of lipoproteins, but also the diet content of macro nutrients and micronutrients should be considered.As doenças cardiovasculares (DCV são a principal causa de morte no mundo ocidental. Entre os fatores de risco modificáveis pela dieta para reduzir os riscos de doenças cardiovasculares destacam-se as concentrações plasmáticas de colesterol total, triglicérides, LDL-C e HDL-C. Medidas dietéticas podem ser adotadas para equilibrar estes componentes do perfil lipídico e, assim, prevenir doenças cardiovasculares. Os principais componentes dos alimentos que afetam o perfil lipídico e cuja ingestão pode ser modificada pela dieta são as gorduras saturadas e gorduras trans, gorduras insaturadas, colesterol, fitosteróis, proteínas vegetais e fibras solúveis. Há uma riqueza de evidências de que gorduras saturadas e trans e colesterol da dieta aumentam as concentrações do colesterol plasmático total e do LDL-C. As gorduras trans também reduzem o HDL-C, uma lipoproteína importante para mediar o transporte reverso do colesterol. Por outro lado, fitosteróis, proteínas vegetais, isoflavonas e fibras solúveis são fatores da dieta protetores na doença cardiovascular, modulando os níveis plasmáticos de lipoproteína. Estes componentes dos alimentos em determinadas concentrações são capazes de reduzir o colesterol total, TG e LDL-C e elevar os níveis plasmáticos de HDL-C. A dieta é, portanto, uma importante ferramenta para a prevenção e controle das doenças cardiovasculares, sendo importante considerá-la como um todo, não apenas os componentes dos alimentos que modulam as concentrações plasmáticas de lipoproteínas, mas também o conteúdo da dieta de macronutrientes e micronutrientes.

    Full Text Available A educação inclusiva envolve dimensões político-administrativas e pedagógicas. O currículo é umas dessas dimensões, e as adequações curriculares aparecem como uma estratégia para que sejam atendidos os princípios de uma escola para todos. Este estudo objetiva caracterizar o campo de estudos da educação inclusiva, por meio de uma revisão da literatura publicada entre os anos 2000 e 2010, em periódicos da área de educação, disponíveis no banco de dados Scielo. As palavras-chave utilizadas foram curricular, currículo, deficiência, educação especial e necessidades especiais. Os resultados demonstram que as produções na área são escassas no que diz respeito às estratégias para efetivação da educação inclusiva, limitando-se, prioritariamente, a reflexões e discussões teóricas que envolvem os princípios e políticas educacionais, pouco retratando experiências didático-pedagógicas que promovam ajustes curriculares e/ou formas de flexibilização do ensino.The Inclusive Education involves political, administrative and pedagogical dimensions. The curriculum is one of these dimensions, and adaptation of curriculum appears as a strategy to comply the principles of a school for all.

    The stoichiometries of kinetochores and their constituent proteins in yeast and vertebrate cells were determined using the histone H3 variant CENP-A, known as Cse4 in budding yeast, as a counting standard. One Cse4-containing nucleosome exists in the centromere (CEN) of each chromosome, so it has been assumed that each anaphase CEN/kinetochore cluster contains 32 Cse4 molecules. We report that anaphase CEN clusters instead contained approximately fourfold more Cse4 in Saccharomyces cerevisiae...

    Genes in the phosphatidyl-ethanolamine-binding protein (PEBP) family are instrumental in regulating the fate of meristems and flowering time. To investigate the role of these genes in the monocotyledonous plant Crocus (Crocus sativus L), an industrially important crop cultivated for its nutritional and medicinal properties, we have cloned and characterized a CENTRORADIALIS/TERMINAL FLOWER1 (CEN/TFL1) like gene, named CsatCEN/TFL1-like, the first reported CEN/TFL1 gene characterized from such a perennial geophyte. Sequence analysis revealed that CsatCEN/TFL1 shows high similarity to its homologous PEBP family genes CEN/TFL1, FT and MFT from a variety of plant species and maintains the same exon/intron organization. Phylogenetic analysis of the CsatCEN/TFL1 amino acid sequence confirmed that the isolated sequences belong to the CEN/TFL1 clade of the PEBP family. CsatCEN/TFL1 transcripts could be detected in corms, flower and flower organs but not in leaves. An alternative spliced transcript was also detected in the flower. Comparison of expression levels of CsatCEN/TFL1 and its alternative spliced transcript in wild type flower and a double flower mutant showed no significant differences. Overexpression of CsatCEN/TFL1 transcript in Arabidopsis tfl1 plants reversed the phenotype of early flowering and terminal flowering of the tfl1 plants to a normal one. Computational analysis of the obtained promoter sequences revealed, next to common binding motifs in CEN/TFL1-like genes as well as other flowering gene promoters, the presence of two CArG binding sites indicative of control of CEN/TFL1 by MADS-box transcription factors involved in crocus flowering and flower organ formation.

    As part of the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) we report the discovery of a pair of faint dwarf galaxies (CenA-MM-Dw1 and CenA-MM-Dw2) at a projected distance of $\\sim$90 kpc from the nearby elliptical galaxy NGC5128 (CenA). We measure a tip of the red giant branch distance to each dwarf, finding $D=3.63 \\pm 0.41$ Mpc for CenA-MM-Dw1 and $D=3.60 \\pm 0.41$ Mpc for CenA-MM-Dw2, both of which are consistent with the distance to NGC5128. A qualitative analysis of the color magnitude diagrams indicates stellar populations consisting of an old, metal-poor red giant branch ($\\gtrsim 12$ Gyr, [Fe/H]$\\sim-1.7$ to -1.9). In addition, CenA-MM-Dw1 seems to host an intermediate-age population as indicated by its candidate asymptotic giant branch stars. The derived luminosities ($M_V=-10.9\\pm0.3$ for CenA-MM-Dw1 and $-8.4\\pm0.6$ for CenA-MM-Dw2) and half-light radii ($r_{h}=1.4\\pm0.04$ kpc for CenA-MM-Dw1 and $0.36\\pm0.08$ kpc for CenA-MM-Dw2) are consistent with those of Local Group dwarfs.

    Full Text Available Research on practices to share and reuse data will inform the design of infrastructure to support data collection, management, and discovery in the long tail of science and technology. These are research domains in which data tend to be local in character, minimally structured, and minimally documented. We report on a ten-year study of the Center for Embedded Network Sensing (CENS, a National Science Foundation Science and Technology Center. We found that CENS researchers are willing to share their data, but few are asked to do so, and in only a few domain areas do their funders or journals require them to deposit data. Few repositories exist to accept data in CENS research areas.. Data sharing tends to occur only through interpersonal exchanges. CENS researchers obtain data from repositories, and occasionally from registries and individuals, to provide context, calibration, or other forms of background for their studies. Neither CENS researchers nor those who request access to CENS data appear to use external data for primary research questions or for replication of studies. CENS researchers are willing to share data if they receive credit and retain first rights to publish their results. Practices of releasing, sharing, and reusing of data in CENS reaffirm the gift culture of scholarship, in which goods are bartered between trusted colleagues rather than treated as commodities.

    Centrin is a low molecular mass (20 KDa) protein that belongs to the EF-hand superfamily. In this work, the interaction between the Tb{sup 3+}-saturated C-terminal domain of Euplotes octocarinatus centrin (Tb{sub 2}-C-EoCen) and 2-p-toluidinylnaphthalene-6-sulfonate (TNS) was investigated using difference UV-vis spectra and the fluorescence spectra methods. In 100 mM N-2-hydroxy-ethylpiperazine-N-2-ethanesulfonic acid (Hepes) at pH 7.4, with the addition of Tb{sub 2}-C-EoCen, four new peaks were observed at 265 nm, 278 nm, 317 nm and 360 nm by absorptivity compared with blank solution of TNS. At the same time, the reaction could be measured by fluorescence spectra. The fluorescence emission of TNS was shifted from 480 nm to 445 nm in the presence of Tb{sub 2}-C-EoCen. Meanwhile, its fluorescence intensity was increased markedly. The 1:1 stoichiometric ratio of C-EoCen to TNS was confirmed by fluorescence titration curves. The conditional binding constants of TNS with C-EoCen and Tb{sub 2}-C-EoCen were calculated to be log K{sub (C-EoCen-TNS)}=5.32{+-}0.04 M{sup -1} and log K{sub (Tb2-C-EoCen-TNS)}=5.58{+-}0.12 M{sup -1}, respectively. In addition, the protein of Tb{sub 2}-C-EoCen binding with melittin was also studied. Based on the fluorescence titration curves, the 1:1 stoichiometric ratio of Tb{sub 2}-C-EoCen to melittin was confirmed. And the conditional binding constant of C-EoCen with melittin was calculated to be log Ka Prime =6.79{+-}0.17 M{sup -1}. - Highlights: Black-Right-Pointing-Pointer Tb{sup 3+} induced conformational changes of protein C-EoCen from closed state to open state. Black-Right-Pointing-Pointer Conformational changes resulted in the exposure of hydrophobic surfaces on C-EoCen. Black-Right-Pointing-Pointer Tb{sub 2}-C-EoCen may bind with target peptide melittin.

  11. Insular dysfunction reflects altered between-network connectivity and severity of negative symptoms in schizophrenia during psychotic remission

    Full Text Available Schizophrenia is characterized by aberrant intrinsic functional connectivity (iFC within and between intrinsic connectivity networks (ICNs, including the Default Mode- (DMN, Salience- (SN and Central Executive Network (CEN. The anterior insula (AI of the SN has been demonstrated to modulate DMN/CEN interactions. Recently, we found that the dependence of DMN/CEN interactions on SN´s right AI activity is altered in patients with schizophrenia in acute psychosis and related to psychotic symptoms, indicating a link between aberrant AI, DMN, CEN and psychosis. However, since structural alterations of the insula are also present during psychotic remission and associated with negative symptoms, impaired AI interaction might be relevant even for psychotic remission and corresponding symptoms. Twelve patients with schizophrenia during psychotic remission and 12 healthy controls were assessed using resting-state fMRI and psychometric examination. High-model-order independent component analysis (ICA of fMRI data revealed ICNs including DMN, SN, and CEN. Scores of iFC within (intra-iFC and between (inter-iFC distinct subsystems of the DMN, SN and CEN were calculated, compared between groups and correlated with the severity of symptoms. Intra-iFC was altered in patients’ SN, DMN, and CEN, including decreased intra-iFC in the left AI within the SN. Patients’ inter-iFC between SN and CEN was increased and correlated with the severity of negative symptoms. Furthermore, decreased intra-iFC of the left AI correlated with both severity of negative symptoms and increased inter-iFC between SN and CEN. Our result provides first evidence for a relationship between AI dysfunction and altered between-network interactions in schizophrenia during psychotic remission, which is related to the severity of negative symptoms. Together with our previous results, data suggest specific SN/DMN/CEN reorganization in schizophrenia with distinct insular pathways for distinct

    In the presence of 1.0 mM Ca 2+, the interaction between Euplotes octocarinatus centrin (EoCen) and melittin (ME) was studied by means of fluorescence spectra. In 0.1 M N-2-hydroxyethylpiperazine- N-2-ethanesulfonic acid (Hepes) and 150 mM NaCl at pH 7.4, fluorescence peak of ME was observed at about 353 nm indicating that micro-environment of Tryptophan (Trp) residue in ME was hydrophilic. With the addition of 3.2 × 10 -4 M calcium saturated EoCen (holoEoCen), the peak of ME was blue-shifted to 339 nm, which may be resulted from micro-environmental changes of the peptide. At the same time, fluorescence emission of ME was increased significantly suggesting that new complex of ME-holoEoCen was formed under the experimental conditions. Based on the fluorescence titration curves, the 1:1 stoichiometric ratio of holoEoCen to ME was confirmed. In addition, the conditional binding constant of holoEoCen with ME was calculated to be log KME-holoEoCen = 6.59 ± 0.14.

    Full Text Available Abstract: The objective of this work was to evaluate Trichoderma harzianum isolates for biological control of white mold in common bean (Phaseolus vulgaris. Five isolates were evaluated for biocontrol of white mold in 'Perola' common bean under field conditions, in the 2009 and 2010 crop seasons. A commercial isolate (1306 and a control treatment were included. Foliar applications at 2x109 conidia mL-1 were performed at 42 and 52 days after sowing (DAS, in 2009, and at 52 DAS in 2010. The CEN287, CEN316, and 1306 isolates decreased the number of Sclerotinia sclerotiorum apothecia per square meter in comparison to the control, in both crop seasons. CEN287, CEN316, and 1306 decreased white mold severity during the experimental period, when compared to the control.

    We present the first result of the Ital-FLAMES survey of red giant branch (RGB) stars in omega Cen. Radial velocities with a precision of ~0.5 km/s are presented for 650 members of omega Cen observed with FLAMES-Giraffe at the Very Large Telescope. We found that stars belonging to the metal -poor (RGB-MP), metal-intemediate (RGB-MInt) and metal-rich (RGB-a) sub -populations of Omega Cen are all compatible with having the same rotational pattern. Our results appear to contradict past findings by Norris et al., who could not detect any rotational signature for metal -rich stars. The slightly higher precision of the present measurements and the much larger sample size, especially for the metal-richer stars, appear as the most likely explanation for this discrepancy. The result presented here weakens the body of evidence in favour of a merger event in the past history of omega Cen.

  9. Inbreeding drives maize centromere evolution.

    Science.gov (United States)

    Schneider, Kevin L; Xie, Zidian; Wolfgruber, Thomas K; Presting, Gernot G

    2016-02-23

    Functional centromeres, the chromosomal sites of spindle attachment during cell division, are marked epigenetically by the centromere-specific histone H3 variant cenH3 and typically contain long stretches of centromere-specific tandem DNA repeats (∼1.8 Mb in maize). In 23 inbreds of domesticated maize chosen to represent the genetic diversity of maize germplasm, partial or nearly complete loss of the tandem DNA repeat CentC precedes 57 independent cenH3 relocation events that result in neocentromere formation. Chromosomal regions with newly acquired cenH3 are colonized by the centromere-specific retrotransposon CR2 at a rate that would result in centromere-sized CR2 clusters in 20,000-95,000 y. Three lines of evidence indicate that CentC loss is linked to inbreeding, including (i) CEN10 of temperate lineages, presumed to have experienced a genetic bottleneck, contain less CentC than their tropical relatives; (ii) strong selection for centromere-linked genes in domesticated maize reduced diversity at seven of the ten maize centromeres to only one or two postdomestication haplotypes; and (iii) the centromere with the largest number of haplotypes in domesticated maize (CEN7) has the highest CentC levels in nearly all domesticated lines. Rare recombinations introduced one (CEN2) or more (CEN5) alternate CEN haplotypes while retaining a single haplotype at domestication loci linked to these centromeres. Taken together, this evidence strongly suggests that inbreeding, favored by postdomestication selection for centromere-linked genes affecting key domestication or agricultural traits, drives replacement of the tandem centromere repeats in maize and other crop plants. Similar forces may act during speciation in natural systems. PMID:26858403

    Full Text Available Centromeres, the specialized chromatin structures that are responsible for equal segregation of chromosomes at mitosis, are epigenetically maintained by a centromere-specific histone H3 variant (CenH3. However, the mechanistic basis for centromere maintenance is unknown. We investigated biochemical properties of CenH3 nucleosomes from Drosophila melanogaster cells. Cross-linking of CenH3 nucleosomes identifies heterotypic tetramers containing one copy of CenH3, H2A, H2B, and H4 each. Interphase CenH3 particles display a stable association of approximately 120 DNA base pairs. Purified centromeric nucleosomal arrays have typical "beads-on-a-string" appearance by electron microscopy but appear to resist condensation under physiological conditions. Atomic force microscopy reveals that native CenH3-containing nucleosomes are only half as high as canonical octameric nucleosomes are, confirming that the tetrameric structure detected by cross-linking comprises the entire interphase nucleosome particle. This demonstration of stable half-nucleosomes in vivo provides a possible basis for the instability of centromeric nucleosomes that are deposited in euchromatic regions, which might help maintain centromere identity.

  16. Isolation and characterization of a novel endoglucanase from a Bursaphelenchus xylophilus metagenomic library.

    Lin Zhang

    Full Text Available A novel gene (designated as cen219 encoding endoglucanase was isolated from a Bursaphelenchus xylophilus metagenomic library by functional screening. Sequence analysis revealed that cen219 encoded a protein of 367 amino acids. SDS-PAGE analysis of purified endoglucanase suggested that Cen219 was a monomeric enzyme with a molecular mass of 40 kDa. The optimum temperature and pH for endoglucanase activity of Cen219 was separately 50 °C and 6.0. It was stable from 30 to 50 °C, and from pH 4.0 to 7.0. The activity was significantly enhanced by Mn(2+ and dramatically reduced by detergent SDS and metals Fe(3+, Cu(2+ or Hg(2+. The enzyme hydrolyzed a wide range of β-1, 3-, and β-1, 4-linked polysaccharides, with varying activities. Activities towards microcrystalline cellulose and filter paper were relatively high, while the highest activity was towards oat gum. The Km and Vmax of Cen219 towards CMC was 17.37 mg/ml and 333.33 U/mg, respectively. The findings have an insight into understanding the molecular basis of host-parasite interactions in B. xylophilus species. The properties also make Cen219 an interesting enzyme for biotechnological application.

    Full Text Available The objective of this work was to evaluate isolates of Trichoderma harzianum regarding biocontrol of common bean seed-borne pathogens, plant growth promotion, and rhizosphere competence. Five isolates of T. harzianum were evaluated and compared with commercial isolate (Ecotrich, Carboxin+Thiram, and an absolute control. Bean seeds of the cultivar Jalo Precoce, contaminated with Aspergillus, Cladosporium, and Sclerotinia sclerotiorum, were microbiolized with antagonists, and seed health tests were carried out. Isolates were evaluated on autoclaved substrate and in field conditions. Ten days after sowing (DAS, plant length was measured. To test rhizosphere competence, isolates were applied in boxes containing autoclaved washed sand, and root colonization was evaluated at 10 DAS, using five plants per box. The most effective isolates in the seed health tests were: CEN287 and CEN289 to control Aspergillus; the commercial isolate to control Cladosporium; and CEN287 and CEN316 to control S. sclerotiorum. Isolates CEN289 and CEN290 promoted bean growth in greenhouse and field. Seed treatment with T. harzianum reduces the incidence of Aspergillus, Cladosporium, and S. sclerotiorum in 'Jalo Precoce' common bean seeds.

  3. Decadal changes in zooplankton of the Northeast U.S. continental shelf.

    Hongsheng Bi

    Full Text Available The abundance of the subarctic copepod, Calanus finmarchicus, and temperate, shelf copepod, Centropages typicus, was estimated from samples collected bi-monthly over the Northeast U.S. continental shelf (NEUS from 1977-2010. Latitudinal variation in long term trends and seasonal patterns for the two copepod species were examined for four sub-regions: the Gulf of Maine (GOM, Georges Bank (GB, Southern New England (SNE, and Mid-Atlantic Bight (MAB. Results suggested that there was significant difference in long term variation between northern region (GOM and GB, and the MAB for both species. C. finmarchicus generally peaked in May - June throughout the entire study region and Cen. typicus had a more complex seasonal pattern. Time series analysis revealed that the peak time for Cen. typicus switched from November - December to January - March after 1985 in the MAB. The long term abundance of C. finmarchicus showed more fluctuation in the MAB than the GOM and GB, whereas the long term abundance of Cen. typicus was more variable in the GB than other sub-regions. Alongshore transport was significantly correlated with the abundance of C. finmarchicus, i.e., more water from north, higher abundance for C. finmarchicus. The abundance of Cen. typicus showed positive relationship with the Gulf Stream north wall index (GSNWI in the GOM and GB, but the GSNWI only explained 12-15% of variation in Cen. typicus abundance. In general, the alongshore current was negatively correlated with the GSNWI, suggesting that Cen. typicus is more abundant when advection from the north is less. However, the relationship between Cen. typicus and alongshore transport was not significant. The present study highlights the importance of spatial scales in the study of marine populations: observed long term changes in the northern region were different from the south for both species.

  4. Single-epitope recognition imaging of native chromatin

    Directory of Open Access Journals (Sweden)

    Wang Hongda

    2008-12-01

    Full Text Available Abstract Background Direct visualization of chromatin has the potential to provide important insights into epigenetic processes. In particular, atomic force microscopy (AFM can visualize single nucleosomes under physiological ionic conditions. However, AFM has mostly been applied to chromatin that has been reconstituted in vitro, and its potential as a tool for the dissection of native nucleosomes has not been explored. Recently we applied AFM to native Drosophila chromatin containing the centromere-specific histone 3 (CenH3, showing that it is greatly enriched in smaller particles. Taken together with biochemical analyses of CenH3 nucleosomes, we propose that centromeric nucleosomes are hemisomes, with one turn of DNA wrapped around a particle consisting of one molecule each of centromere-specific CenH3, H4, H2A and H2B. Results Here we apply a recognition mode of AFM imaging to directly identify CenH3 within histone core particles released from native centromeric chromatin. More than 90% of these particles were found to be tetrameric in height. The specificity of recognition was confirmed by blocking with a CenH3 peptide, and the strength of the interaction was quantified by force measurements. These results imply that the particles imaged by AFM are indeed mature CenH3-containing hemisomes. Conclusion Efficient and highly specific recognition of CenH3 in histone core particles isolated from native centromeric chromatin demonstrates that tetramers are the predominant form of centromeric nucleosomes in mature tetramers. Our findings provide proof of principle that this approach can yield insights into chromatin biology using direct and rapid detection of native nucleosomes in physiological salt concentrations.

    Consistent structural and functional abnormities have been detected in the salience network (SN) and the central-executive network (CEN) in schizophrenia. SN, known for its critical role in switching CEN and default-mode network (DMN) during cognitively demanding tasks, is proved to show aberrant regulation on the interaction between DMN and CEN in schizophrenia. However, it has not been elucidated whether there is a direct alteration of structural and functional connectivity between SN and CEN. 22 schizophrenia patients and 21 healthy controls were recruited for functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) in present study. The results show that schizophrenia patients had lower fractional anisotropy (FA) in right inferior long fasciculus (ILF), left inferior fronto-occipital fasciculus (IFOF) and callosal body than healthy controls. Significantly reduced functional connectivity was also found between right fronto-insular cortex (rFIC) and right posterior parietal cortex (rPPC). FA in right ILF was positively correlated with the functional connectivity of rFIC-rPPC. Therefore, we proposed a disruption of structural and functional connectivity and a positive anatomo-functional relationship in SN-CEN circuit, which might account for a core feature of schizophrenia.

    Full Text Available O presente estudo apresenta dois diferentes cenários de aproveitamento energético dos Resíduos Sólidos Urbanos (RSU, para o Município de Nova Iguaçu. O “Cenário I” contempla o ganho energético, proveniente do metano gerado do aterramento de 100% dos RSU, gerado na localidade. Já o “Cenário II” estima o ganho energético com a reciclagem de materiais como papel/papelão, plástico, metal e vidro, que geralmente, são depositados no aterro, e do metano gerado proveniente da fração orgânica do RSU, deste município. A quantidade de energia elétrica gerada do metano proveniente do aterro, mais a energia elétrica conservada levando em conta os índices de Morris proveniente da reciclagem, ambos do Cenário II corresponderam a um ganho energético de 5.633 MWh dia-1, aproximadamente 64%, maior que a quantidade de energia elétrica gerada, somente do metano proveniente do aterro no Cenário I, que corresponde a 2.034 MWh dia-1.

  7. Holocentromeres are dispersed point centromeres localized at transcription factor hotspots.

    Centromeres vary greatly in size and sequence composition, ranging from 'point' centromeres with a single cenH3-containing nucleosome to 'regional' centromeres embedded in tandemly repeated sequences to holocentromeres that extend along the length of entire chromosomes. Point centromeres are defined by sequence, whereas regional and holocentromeres are epigenetically defined by the location of cenH3-containing nucleosomes. In this study, we show that Caenorhabditis elegans holocentromeres are organized as dispersed but discretely localized point centromeres, each forming a single cenH3-containing nucleosome. These centromeric sites co-localize with kinetochore components, and their occupancy is dependent on the cenH3 loading machinery. These sites coincide with non-specific binding sites for multiple transcription factors ('HOT' sites), which become occupied when cenH3 is lost. Our results show that the point centromere is the basic unit of holocentric organization in support of the classical polycentric model for holocentromeres, and provide a mechanistic basis for understanding how centromeric chromatin might be maintained.

    The Dynamo Clinical Trial evaluates long-term stellar magnetic health through periodic X-ray examinations (by the Chandra Observatory). So far, there are only three subjects enrolled in the DTC: Alpha Centauri A (a solar-like G dwarf), Alpha Cen B (an early K dwarf, more active than the Sun), and Alpha Canis Majoris A (Procyon, a mid-F subgiant similar in activity to the Sun). Of these, Procyon is a new candidate, so it is too early to judge how it will fare. Of the other two, Alpha Cen B has responded well, with a steady magnetic heartbeat of about 8 years duration. The sickest of the bunch, Alpha Cen A, was in magnetic cardiac arrest during 2005-2010, but has begun responding to treatment in recent years, and seems to be successfully cycling again, perhaps achieving a new peak of magnetic health in the 2016 time frame. If this is the case, it has been 20 years since A's last healthful peak, significantly longer than the middle-aged Sun's 11-year magnetic heartbeat, but perhaps in line with Alpha Cen A's more senescent state (in terms of "relative evolutionary age," apparently an important driver of activity). (By the way, don't miss the exciting movie of the Alpha Cen stars' 20-year X-ray dance.)

    March 2003 the Executive Committee of the International Energy Agency's Implementing Agreement on Advanced Motor fuels (IEA/AMF) decided to continue annex XXVII 'Standardization of alternative fuels' with a second phase. The purpose of the second phase was to go further in the contacts with the International Organization for Standardization (ISO) as well as the European Committee for Standardization (CEN) and their technical committees, to better understand their needs and to investigate how IEA/AMF could contribute to their work. It was also scheduled to put forward proposals on how IEA/AMF could cooperate with CEN and ISO and their technical committees (TC: s), primarily ISO/TC 28 'Petroleum Products and Lubricants' and CEN/TC 19 'Petroleum Products, Lubricants and Related Products'. The main part of the work in IEA/AMF annex XXVII phase two has focused on personal contacts within CEN/TC 19 and ISO/TC 28, but also on data and information collection from websites and written information. Together with the analysis of this information, the internal organization of a cooperation between IEA/AMF and ISO/TC 28 and of a cooperation between IEA/AMF and CEN/TC 19 have also been discussed and analysed.

    [Abridged] Debris discs around main-sequence stars indicate the presence of larger rocky bodies. The components of the nearby binary aCentauri have higher than solar metallicities, which is thought to promote giant planet formation. We aim to determine the level of emission from debris in the aCen system. Having already detected the temperature minimum, Tmin, of aCenA, we here attempt to do so also for the companion aCenB. Using the aCen stars as templates, we study possible effects Tmin may have on the detectability of unresolved dust discs around other stars. We use Herschel and APEX photometry to determine the stellar spectral energy distributions. In addition, we use APEX for spectral line mapping to study the complex background around aCen seen in the photometric images. Models of stellar atmospheres and discs are used to estimate the amount of debris around these stars. For solar-type stars, a fractional dust luminosity fd 2e-7 could account for SEDs that do not exhibit the Tmin-effect. Slight excesses ...

    Proxima Centauri b provides an unprecedented opportunity to understand the evolution and nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its star's habitable zone, multiple plausible evolutionary paths could have generated different environments that may or may not be habitable. Here we use 1D coupled climate-photochemical models to generate self-consistent atmospheres for evolutionary scenarios predicted in our companion paper (Barnes et al., 2016). These include high-O2, high-CO2, and more Earth-like atmospheres, with either oxidizing or reducing compositions. We show that these modeled environments can be habitable or uninhabitable at Proxima Cen b's position in the habitable zone. We use radiative transfer models to generate synthetic spectra and thermal phase curves for these simulated environments, and instrument models to explore our ability to discriminate between possible planetary states. These results are applicable not only to Proxima Cen b, but to other terre...

  13. Enrichment by supernovae in globular clusters with multiple populations

    2009-01-01

    The most massive globular cluster in the Milky Way, omega Centauri, is thought to be the remaining core of a disrupted dwarf galaxy, as expected within the model of hierarchical merging. It contains several stellar populations having different heavy elemental abundances supplied by supernovae -- a process known as metal enrichment. Although M22 appears to be similar to omega Cen, other peculiar globular clusters do not. Therefore omega Cen and M22 are viewed as exceptional, and the presence of chemical inhomogeneities in other clusters is seen as `pollution' from the intermediate-mass asymptotic-giant-branch stars expected in normal globular clusters. Here we report Ca abundances for seven globular clusters and compare them to omega Cen. Calcium and other heavy elements can only be supplied through numerous supernovae explosions of massive stars in these stellar systems, but the gravitational potentials of the present-day clusters cannot preserve most of the ejecta from such explosions. We conclude that these...

  14. Safety culture in a Belgian nuclear research centre from a social science point of view

    International Nuclear Information System (INIS)

    This paper is the result of a reflection within the framework of a Ph.D. research at SCK-CEN (Belgian Nuclear Research Centre) in collaboration with the University of Liege. The starting point of the work was the 'safety culture' model presented in the IAEA report 75-INSAG-4. This model is applied to the working organization of the SCK-CEN, also considering the safety culture as an open concept given its multi dimensionality. The methodology is based on three methods: observations, focus groups and interviews. The fieldwork was limited to two main installations: a research reactor, and a dismantling site. The preliminary findings are based on the data resulting from 4 Focus Groups. The most prominent components of a safety culture and the multiplicity of safety cultures in a large organization such as SCK-CEN will be discussed. (author)

    The BR2 reactor is a 100 MW{sub th} High-Flux 'Material Testing Reactor' which first became operational in 1963 and has since been refurbished in 1995 to 1997. It is operated by the Belgian Nuclear Research Centre, SCK CEN, in the framework of programmes related to the development of structural materials and nuclear fuels for fission and fusion reactors. Serious maintenance efforts are currently made by SCK CEN to secure its safe operation until at least 2023. This would guarantee the continuity of the activities in which the BR2 reactor is involved through its replacement by an Accelerator Driven System (ADS), MYRRHA, scheduled to be operated by SCK CEN from 2023.

    Omega Centauri, the Milky Way's most massive and enigmatic old stellar cluster, offers a treasure trove of astronomical discovery and controversy, including debate about the existence of an intermediate mass black hole (IMBH) buried in the cluster's core. We report preliminary results of deep 290 ksec) Chandra ACIS-I imaging of Omega Cen, which reveals no X-ray source at the cluster center reported by Anderson and van der Marel (2010), or at any other proposed center for the cluster. We discuss the significance of this new X-ray limit for the possible presence of an IMBH in Omega Cen. We also briefly describe our multiwavelength imaging and spectroscopic campaigns, which probe Omega Cen's binary populations, and the light they shed on the cluster's dynamical history.

    The objective of SCK-CEN's R and D programme on decision strategies is (1) to develop theories, methods and software tools which help decision makers shape, analyse and understand their decisions; (2) to study group processes in decision making; (3) to apply theories, methods and tools in a context related to nuclear emergency preparedness and more generally to support in a context dealing with ionising radiation; (4) to increase SCK-CEN's knowledge on general emergency preparedness and to introduce SCK-CEN staff to computer supported decision techniques. Ongoing R and D has two components: (1) the study of the use of information and knowledge transfer in group decision processes, and more specific studying important factors when computers are used as information source and communication tool; and (2) the study of preference modelling individually and during group decision processes. Principal achievements in 1999 are described.

  19. Effects of self-consistency violation in Hartree-Fock RPA calculations for nuclear giant resonances revisited

    2006-01-01

    We provide accurate assessments of the consequences of violations of self-consistency in Hartree-Fock (HF) based random phase approximation (RPA) calculations of the centroid energy $E_{cen}$ of isoscalar and isovector giant resonances of multi-polarities $L=0-3$ in a wide range of nuclei. This is done by carrying out highly accurate HF-RPA calculations neglecting the particle-hole (ph) spin-orbit or Coulomb interaction in the RPA and comparing with the fully self-consistent HF-RPA results. We find that the shifts in the value of $E_{cen}$ due to self-consistency violation associated with the spin-orbit and Coulomb interactions are comparable or larger than the current experimental errors in $E_{cen}$.

  20. Two-component signal transduction pathways regulating growth and cell cycle progression in a bacterium: a system-level analysis.

    2005-10-01

    Full Text Available Two-component signal transduction systems, comprised of histidine kinases and their response regulator substrates, are the predominant means by which bacteria sense and respond to extracellular signals. These systems allow cells to adapt to prevailing conditions by modifying cellular physiology, including initiating programs of gene expression, catalyzing reactions, or modifying protein-protein interactions. These signaling pathways have also been demonstrated to play a role in coordinating bacterial cell cycle progression and development. Here we report a system-level investigation of two-component pathways in the model organism Caulobacter crescentus. First, by a comprehensive deletion analysis we show that at least 39 of the 106 two-component genes are required for cell cycle progression, growth, or morphogenesis. These include nine genes essential for growth or viability of the organism. We then use a systematic biochemical approach, called phosphotransfer profiling, to map the connectivity of histidine kinases and response regulators. Combining these genetic and biochemical approaches, we identify a new, highly conserved essential signaling pathway from the histidine kinase CenK to the response regulator CenR, which plays a critical role in controlling cell envelope biogenesis and structure. Depletion of either cenK or cenR leads to an unusual, severe blebbing of cell envelope material, whereas constitutive activation of the pathway compromises cell envelope integrity, resulting in cell lysis and death. We propose that the CenK-CenR pathway may be a suitable target for new antibiotic development, given previous successes in targeting the bacterial cell wall. Finally, the ability of our in vitro phosphotransfer profiling method to identify signaling pathways that operate in vivo takes advantage of an observation that histidine kinases are endowed with a global kinetic preference for their cognate response regulators. We propose that this

    Fresh mung bean sprouts have been identified as a source of many Salmonella outbreaks worldwide. The aim of this study was to develop a rapid and accurate detection methodology for low levels of healthy and sanitizer-injured Salmonella on mung bean sprouts using real-time PCR coupled with either immunomagnetic separation (PCR-IMS) or centrifugation (PCR-cen). Initially, three parameters of IMS; specificity/sensitivity, bacterial concentration and bead incubation time were optimized. Secondly, limit of detection (LOD) was determined for the optimized PCR-IMS and PCR-cen. These two methods were compared against PCR alone (PCR) and the standard culture method (ISO) for their ability to detect Salmonella using inoculated and uninoculated sprouts. Under optimum IMS conditions (10(5)CFU/ml for 30 min), capture efficiency of Salmonella in sprout suspensions was lower than 40%, most probably due to the non-specific binding of the background microbiota. PCR-IMS and PCR-cen had a similar LOD at 10(3)CFU/ml, which was one log unit lower than PCR. Enrichment of 10h was sufficient to detect 100% of the inoculated sprouts with both PCR-IMS and PCR-cen, which was significantly faster compared to PCR and the ISO method. Moreover, the validation study using uninoculated sprouts revealed that PCR-IMS and PCR-cen were equally effective on Salmonella detection, showing 98.3% accuracy. These results suggest that PCR-cen would be the effective and less costly method for the detection of both healthy and sanitizer-injured Salmonella on mung bean sprouts.

    Full Text Available Visceral leishmaniasis (VL is a neglected tropical disease and is fatal if untreated. There is no vaccine available against leishmaniasis. The majority of patients with cutaneous leishmaniasis (CL or VL develop a long-term protective immunity after cure from infection, which indicates that development of an effective vaccine against leishmaniasis is possible. Such protection may also be achieved by immunization with live attenuated parasites that do not cause disease. We have previously reported a protective response in mice, hamsters and dogs with Leishmania donovani centrin gene knock-out parasites (LdCen-/-, a live attenuated parasite with a cell division specific centrin1 gene deletion. In this study we have explored the effects of salivary protein LJM19 as an adjuvant and intradermal (ID route of immunization on the efficacy of LdCen-/- parasites as a vaccine against virulent L. donovani.To explore the potential of a combination of LdCen-/- parasites and salivary protein LJM19 as vaccine antigens, LdCen-/- ID immunization followed by ID challenge with virulent L. donovani were performed in hamsters in a 9-month follow up study. We determined parasite burden (serial dilution, antibody production (ELISA and cytokine expression (qPCR in these animals. Compared to controls, animals immunized with LdCen-/- + LJM19 induced a strong antibody response, a reduction in spleen and liver parasite burden and a higher expression of pro-inflammatory cytokines after immunization and one month post-challenge. Additionally, a low parasite load in lymph nodes, spleen and liver, and a non-inflamed spleen was observed in immunized animals 9 months after the challenge infection.Our results demonstrate that an ID vaccination using LdCen-/-parasites in combination with sand fly salivary protein LJM19 has the capability to confer long lasting protection against visceral leishmaniasis that is comparable to intravenous or intracardial immunization.

    Species of the legume genera Lathyrus and Pisum possess chromosomes that exhibit a unique structure of their centromeric regions, which is clearly apparent during metaphase by the formation of extended primary constrictions which span up to a third of the length of the chromosome. In addition, these species express two different variants of the CenH3 protein which are co-localized in multiple domains along the poleward surface of the primary constrictions. Here, we show that the constrictions represent a distinct type of chromatin differing from the chromosome arms. In metaphase, histone phosphorylation patterns including H3S10ph, H3S28ph, and H3T3ph were observed along the entire constriction, in a way similar to holocentric chromosomes. On the other hand, distribution of phosphorylated H2AT120 was different from that previously reported from either, holocentric and monocentric chromosomes, occurring at chromatin surrounding but not overlapping CenH3 domains. Since some of these phosphorylations play a role in chromatid cohesion, it can be assumed that they facilitate correct chromosome segregation by ensuring that multiple separate CenH3 domains present on the same chromatid are oriented toward the same pole. The constrictions also displayed distinct patterns of histone methylation marks, being enriched in H3K9me2 and depleted in H3K4me3 and H3K27me2 compared to the chromosome arms. Super-resolution fluorescence microscopy revealed that although both CenH3 protein variants are present in all CenH3 domains detected on metaphase chromosomes, they are only partially co-localized while there are chromatin subdomains which are mostly made of only one CenH3 variant. Taken together, these data revealed specific features of extended primary constrictions of Lathyrus and Pisum and support the idea that they may represent an intermediate stage between monocentric and holocentric chromosomes.

  6. Altered intrinsic functional coupling between core neurocognitive networks in Parkinson's disease

    2015-01-01

    Full Text Available Parkinson's disease (PD is largely attributed to disruptions in the nigrostriatal dopamine system. These neurodegenerative changes may also have a more global effect on intrinsic brain organization at the cortical level. Functional brain connectivity between neurocognitive systems related to cognitive processing is critical for effective neural communication, and is disrupted across neurological disorders. Three core neurocognitive networks have been established as playing a critical role in the pathophysiology of many neurological disorders: the default-mode network (DMN, the salience network (SN, and the central executive network (CEN. In healthy adults, DMN–CEN interactions are anti-correlated while SN–CEN interactions are strongly positively correlated even at rest, when individuals are not engaging in any task. These intrinsic between-network interactions at rest are necessary for efficient suppression of the DMN and activation of the CEN during a range of cognitive tasks. To identify whether these network interactions are disrupted in individuals with PD, we used resting state functional magnetic resonance imaging (rsfMRI to compare between-network connectivity between 24 PD participants and 20 age-matched controls (MC. In comparison to the MC, individuals with PD showed significantly less SN–CEN coupling and greater DMN–CEN coupling during rest. Disease severity, an index of striatal dysfunction, was related to reduced functional coupling between the striatum and SN. These results demonstrate that individuals with PD have a dysfunctional pattern of interaction between core neurocognitive networks compared to what is found in healthy individuals, and that interaction between the SN and the striatum is even more profoundly disrupted in those with greater disease severity.

Characterization of the two resulting strains in two standard conditions revealed that the S288c background strain...... produced up to 10-fold higher amounts of vanillin-β-glucoside compared to CEN.PK. This study demonstrates that yeast strain background may play a major role in the outcome of newly developed cell factories for production of a given product....

    This paper studies the collinear equilibrium points of the restricted three-body problem under the effects of the oblateness of the bigger primary and the radiation pressure of the smaller primary. Using a semi-analytical and numerical approach, the positions and linear stability of these points are investigated for the binary systems RXJ 0450.1-5856 and Nova Cen 1969 (Cen X-4), and found to be affected by the oblateness and radiation pressure. The collinear points remain unstable in the sense of Lyapunov.

In order to work better and more ethically, SCK-CEN has invested 3 million euros in a brand-new animal facility. This makes it possible to carry out research under the best possible conditions for both humans and mice.

  16. Cepheid Companions and the Masses of Cepheids

    Science.gov (United States)

    Bohm-Vitense, E.; Borutzki, S.; Harris, H.

    The authors have observed in the ultraviolet the hot companions of the Cepheids SV Per, RW Cam, SY Nor and KN Cen. The study of the absolute and relative intensities reveals that all, except the companion for KN Cen are evolved stars which should fit on almost the same mass track as the Cepheid. The authors find however that with generally accepted reddening values the companions of at least SV Per and RW Cam are too faint. Either the Cepheid loops are more luminous than presently calculated or the reddening is larger than presently accepted.

    Context. Debris discs around main-sequence stars indicate the presence of larger rocky bodies. The components of the nearby, solar-type binary Centauri have metallicities that are higher than solar, which is thought to promote giant planet formation. Aims. We aim to determine the level of emission from debris around the stars in the Cen system. This requires knowledge of their photospheres.Having already detected the temperature minimum, Tmin, of CenA at far-infrared wavelengths, we here attempt to do the same for the moreactive companion Cen B. Using the Cen stars as templates, we study the possible eects that Tmin may have on the detectability of unresolveddust discs around other stars. Methods.We used Herschel-PACS, Herschel-SPIRE, and APEX-LABOCA photometry to determine the stellar spectral energy distributions in thefar infrared and submillimetre. In addition, we used APEX-SHeFI observations for spectral line mapping to study the complex background around Cen seen in the photometric images. Models of stellar atmospheres and of particulate discs, based on particle simulations and in conjunctionwith radiative transfer calculations, were used to estimate the amount of debris around these stars. Results. For solar-type stars more distant than Cen, a fractional dust luminosity fd LdustLstar 2 107 could account for SEDs that do not exhibit the Tmin eect. This is comparable to estimates of fd for the Edgeworth-Kuiper belt of the solar system. In contrast to the far infrared,slight excesses at the 2:5 level are observed at 24 m for both CenA and B, which, if interpreted as due to zodiacal-type dust emission, wouldcorrespond to fd (13) 105, i.e. some 102 times that of the local zodiacal cloud. Assuming simple power-law size distributions of the dustgrains, dynamical disc modelling leads to rough mass estimates of the putative Zodi belts around the Cen stars, viz.4106 M$ of 4 to 1000 msize grains, distributed according to n(a) a3:5. Similarly, for filled-in Tmin

  5. Transposons play an important role in the evolution and diversification of centromeres among closely related species

    Directory of Open Access Journals (Sweden)

    Scott eJackson

    2015-04-01

    Full Text Available Centromeres are important chromosomal regions necessary for eukaryotic cell segregation and replication. Due to high amounts of tandem repeats and transposons, centromeres have been difficult to sequence in most multicellular organisms, thus their sequence structure and evolution are poorly understood. In this study, we analyzed transposons in the centromere 8 (Cen8 from the African cultivated rice (O. glaberrima and two subspecies of the Asian cultivated rice (O. sativa, indica and japonica. We detected much higher transposon contents (>69% in centromere regions than in the whole genomes of O. sativa ssp japonica and O. glaberrima (~35%. We compared the three Cen8s and identified numerous recent insertions of transposons that were frequently organized into multiple-layer nested blocks, similar to nested transposons in maize. Except for the Hopi retrotransposon, all LTR retrotransposons were shared but exhibit different abundances amongst the three Cen8s. Even though a majority of the transposons were located in intergenic regions, some gene-related transposons were found and may be involved in gene diversification. Chromatin immunoprecipitated (ChIP data analysis revealed that 165 families from both Class I and Class II transposons were found in CENH3-associated chromatin sequences. These results indicate essential roles for transposons in centromeres and that the rapid divergence of the Cen8 sequences between the two cultivated rice species was primarily caused by recent transposon insertions.

  13. Structure, Function, and Evolution of Rice Centromeres

    Energy Technology Data Exchange (ETDEWEB)

    Jiang, Jiming

    2010-02-04

    The centromere is the most characteristic landmark of eukaryotic chromosomes. Centromeres function as the site for kinetochore assembly and spindle attachment, allowing for the faithful pairing and segregation of sister chromatids during cell division. Characterization of centromeric DNA is not only essential to understand the structure and organization of plant genomes, but it is also a critical step in the development of plant artificial chromosomes. The centromeres of most model eukaryotic species, consist predominantly of long arrays of satellite DNA. Determining the precise DNA boundary of a centromere has proven to be a difficult task in multicellular eukaryotes. We have successfully cloned and sequenced the centromere of rice chromosome 8 (Cen8), representing the first fully sequenced centromere from any multicellular eukaryotes. The functional core of Cen8 spans ~800 kb of DNA, which was determined by chromatin immunoprecipitation (ChIP) using an antibody against the rice centromere-specific H3 histone. We discovered 16 actively transcribed genes distributed throughout the Cen8 region. In addition to Cen8, we have characterized eight additional rice centromeres using the next generation sequencing technology. We discovered four subfamilies of the CRR retrotransposon that is highly enriched in rice centromeres. CRR elements are constitutively transcribed and different CRR subfamilies are differentially processed by RNAi. These results suggest that different CRR subfamilies may play different roles in the RNAi-mediated pathway for formation and maintenance of centromeric chromatin.

    We present new wide-field observations of Centaurus A (Cen A) and the surrounding region at 118 MHz with the Murchison Widefield Array (MWA) 32-tile prototype, with which we investigate the spectral-index distribution of Cen A's giant radio lobes. We compare our images to 1.4 GHz maps of Cen A and compute spectral indices using temperature-temperature plots and spectral tomography. We find that the morphologies at 118 MHz and 1.4 GHz match very closely apart from an extra peak in the southern lobe at 118 MHz, which provides tentative evidence for the existence of a southern counterpart to the northern middle lobe of Cen A. Our spatially-averaged spectral indices for both the northern and southern lobes are consistent with previous analyses, however we find significant spatial variation of the spectra across the extent of each lobe. Both the spectral-index distribution and the morphology at low radio frequencies support a scenario of multiple outbursts of activity from the central engine. Our results are consi...

    CERN Document Server

    Gardner, Carl L; Scannapieco, Evan; Windhorst, Rogier A

    2016-01-01

    Recent Hubble Space Telescope (HST) observations of the extragalactic radio source Centaurus A (Cen A) display a young stellar population around the southwest tip of the inner filament 8.5 kpc from the Cen A galactic center, with ages in the range of 1-3 Myr. Crockett et al. (2012) argue that the transverse bow shock of the Cen A jet triggered this star formation as it impacted dense molecular cores of clouds in the filament. To test this hypothesis, we perform three-dimensional numerical simulations of induced star formation by the jet bow shock in the inner filament of Cen A, using a positivity preserving WENO method to solve the equations of gas dynamics with radiative cooling. We find that star clusters form inside a bow-shocked molecular cloud when the maximum initial density of the cloud is > 40 H2 molecules/cm^3. In a typical molecular cloud of mass 10^6 M_sun and diameter 200 pc, approximately 20 star clusters of mass 10^3 M_sun are formed, matching the HST images.

    Detection of gas-phase chemicals finds a wide variety of applications, including food and beverages, fragrances, environmental monitoring, chemical and biochemical processing, medical diagnostics, and transportation. One approach for these tasks is to use arrays of highly sensitive and selective sensors as an electronic nose. Here, we present a high performance chemiresistive electronic nose (CEN) based on an array of metal oxide thin films, metal-catalyzed thin films, and nanostructured thin films. The gas sensing properties of the CEN show enhanced sensitive detection of H2S, NH3, and NO in an 80% relative humidity (RH) atmosphere similar to the composition of exhaled breath. The detection limits of the sensor elements we fabricated are in the following ranges: 534 ppt to 2.87 ppb for H2S, 4.45 to 42.29 ppb for NH3, and 206 ppt to 2.06 ppb for NO. The enhanced sensitivity is attributed to the spillover effect by Au nanoparticles and the high porosity of villi-like nanostructures, providing a large surface-to-volume ratio. The remarkable selectivity based on the collection of sensor responses manifests itself in the principal component analysis (PCA). The excellent sensing performance indicates that the CEN can detect the biomarkers of H2S, NH3, and NO in exhaled breath and even distinguish them clearly in the PCA. Our results show high potential of the CEN as an inexpensive and noninvasive diagnostic tool for halitosis, kidney disorder, and asthma. PMID:27456161

    DY Cen has shown a steady fading of its visual light by about one magnitude in the last 40 yr, suggesting a secular increase in its effective temperature. We have conducted non-local thermodynamic equilibrium (LTE) and LTE abundance analyses to determine the star's effective temperature, surface gravity, and chemical composition using high-resolution spectra obtained over two decades. The derived stellar parameters for three epochs suggest that DY Cen has evolved at a constant luminosity and has become hotter by about 5000 K in 23 yr. We show that the derived abundances remain unchanged for the three epochs. The derived abundances of the key elements, including F and Ne, are as observed for the extreme helium stars resulting from a merger of a He white dwarf with a C-O white dwarf. Thus DY Cen by chemical composition appears to also be a product of a merger of two white dwarfs. This appearance seems to be at odds with the recent suggestion that DY Cen is a single-lined spectroscopic binary.

  8. Social Sciences in Nuclear Research

    International Nuclear Information System (INIS)

    In 1998, an initiative was taken by SCK-CEN to include social sciences and humanities into its research programme. As a result, two working groups were created to discuss two broad items: (1) ethical choices in radiation protection; and (2) the role and culture of nuclear experts. The general objectives of SCK-CEN's social sciences programme are: (1) to improve the nuclear research approach by integrating social sciences - where needed- to solve complex problems in interaction with society; (2) to stimulate university collaboration with social disciplines in learning process towards transdisciplinary and improved social responsibility; (3) to improve the training of nuclear experts of SCK-CEN by gaining insight in their expert culture and implicit ethical choices; (4) to develop projects and an original transdisciplinary programme and project management by involving young and senior scientists, a variety of university opinions and relevant actors from industry and society. Along these lines, projects were developed on sustainability and nuclear development, transgenerational ethics related to disposal of long-lived radioactive waste and cognitive dissonance effects, legal aspects and liability, non-radiological aspects of nuclear emergencies and safety. Progress and major achievements in SCK-CEN's social science programme in 2000 are summarised

  11. CENP-A exceeds microtubule attachment sites in centromere clusters of both budding and fission yeast.

    Science.gov (United States)

    Coffman, Valerie C; Wu, Pengcheng; Parthun, Mark R; Wu, Jian-Qiu

    2011-11-14

    The stoichiometries of kinetochores and their constituent proteins in yeast and vertebrate cells were determined using the histone H3 variant CENP-A, known as Cse4 in budding yeast, as a counting standard. One Cse4-containing nucleosome exists in the centromere (CEN) of each chromosome, so it has been assumed that each anaphase CEN/kinetochore cluster contains 32 Cse4 molecules. We report that anaphase CEN clusters instead contained approximately fourfold more Cse4 in Saccharomyces cerevisiae and ~40-fold more CENP-A (Cnp1) in Schizosaccharomyces pombe than predicted. These results suggest that the number of CENP-A molecules exceeds the number of kinetochore-microtubule (MT) attachment sites on each chromosome and that CENP-A is not the sole determinant of kinetochore assembly sites in either yeast. In addition, we show that fission yeast has enough Dam1-DASH complex for ring formation around attached MTs. The results of this study suggest the need for significant revision of existing CEN/kinetochore architectural models. PMID:22084306

  14. Photometry of the long period dwarf nova MU Centauri

    Science.gov (United States)

    2016-07-01

    Even among the brighter cataclysmic variables an appreciable number of objects exist about which not much is known. One of them, MU Cen, was observed as part of a small project to better characterize these neglected systems. The temporal variations of the brightness of MU Cen during quiescence were studied in order to find clues to the structure of the system and its behavior on time scales of hours and shorter. Light curves observed in white light at a time resolution of a few seconds and with a duration of several hours, obtained in six nights and spanning a total time base of five months, were investigated using different time series analysis tools, as well as model fits. The light curve of MU Cen is dominated by ellipsoidal variations of the secondary star. The refined orbital period is Porb = 0.341883 days. Model fits permit to constrain the temperature of the secondary star to ˜5000 K and the orbital inclination to 50° ≤ i ≤ 65°. The latter result permits estimates of the component masses which are probably somewhat smaller that derived in previous publications. A second persistent period of P2 = 0.178692 days was also identified. Its origin remains unclear. As all cataclysmic variables, MU Cen exhibits flickering, however, on a rather low level. Its frequency behavior is normal for quiescent dwarf novae. There are indications that the individual flickering events are not always independent but can lead to effects reminiscent of quasi-periodic oscillations.

    2002-01-01

    We present results of a spectroscopic survey of X-ray- and proper motion-selected samples of late-type stars in the Lower Cen-Cru (LCC) and Upper Cen-Lup (UCL) subgroups of the nearest OB association: Sco-Cen. The primary goals of the survey are to determine the star-formation history of the OB subgroups, and to assess the frequency of accreting stars in a sample dominated by ``post-T Tauri'' pre-MS stars. We investigate two samples: (1) ACT and TRC proper motion candidates with X-ray counterparts in the ROSAT All-Sky Survey BSC, and (2) G and K-type Hipparcos candidate members (de Zeeuw et al. 1999). We obtained optical spectra of 130 candidates with the MSSSO 2.3-m DBS. Pre-MS stars were identified by (1) strong Li 6707A absorption, (2) subgiant surface gravities, (3) proper motions consistent with Sco-Cen membership, and (4) HRD positions consistent with being pre-MS. We demonstrate that measuring the gravity-sensitive band-ratio of Sr II 4077A to Fe I 4071A is a valuable means of discriminating pre-MS and...

  12. Euchromatic subdomains in rice centromeres are associated with genes and transcription.

    Wu, Yufeng; Kikuchi, Shinji; Yan, Huihuang; Zhang, Wenli; Rosenbaum, Heidi; Iniguez, A Leonardo; Jiang, Jiming

    2011-11-01

    The presence of the centromere-specific histone H3 variant, CENH3, defines centromeric (CEN) chromatin, but poorly understood epigenetic mechanisms determine its establishment and maintenance. CEN chromatin is embedded within pericentromeric heterochromatin in most higher eukaryotes, but, interestingly, it can show euchromatic characteristics; for example, the euchromatic histone modification mark dimethylated H3 Lys 4 (H3K4me2) is uniquely associated with animal centromeres. To examine the histone marks and chromatin properties of plant centromeres, we developed a genomic tiling array for four fully sequenced rice (Oryza sativa) centromeres and used chromatin immunoprecipitation-chip to study the patterns of four euchromatic histone modification marks: H3K4me2, trimethylated H3 Lys 4, trimethylated H3 Lys 36, and acetylated H3 Lys 4, 9. The vast majority of the four histone marks were associated with genes located in the H3 subdomains within the centromere cores. We demonstrate that H3K4me2 is not a ubiquitous component of rice CEN chromatin, and the euchromatic characteristics of rice CEN chromatin are hallmarks of the transcribed sequences embedded in the centromeric H3 subdomains. We propose that the transcribed sequences located in rice centromeres may provide a barrier preventing loading of CENH3 into the H3 subdomains. The separation of CENH3 and H3 subdomains in the centromere core may be favorable for the formation of three-dimensional centromere structure and for rice centromere function.

  13. Genome-wide mapping of cytosine methylation revealed dynamic DNA methylation patterns associated with genes and centromeres in rice.

    Science.gov (United States)

    Yan, Huihuang; Kikuchi, Shinji; Neumann, Pavel; Zhang, Wenli; Wu, Yufeng; Chen, Feng; Jiang, Jiming

    2010-08-01

    We conducted genome-wide mapping of cytosine methylation using methylcytosine immunoprecipitation combined with Illumina sequencing. The chromosomal distribution pattern of methylated DNA is similar to the heterochromatin distribution pattern on rice chromosomes. The DNA methylation patterns of rice genes are similar to those in Arabidopsis thaliana, including distinct methylation patterns asssociated with gene bodies and promoters. The DNA sequences in the core domains of rice Cen4, Cen5 and Cen8 showed elevated methylation levels compared with sequences in the pericentromeric regions. In addition, elevated methylation levels were associated with the DNA sequences in the CENH3-binding subdomains, compared with the sequences in the flanking H3 subdomains. In contrast, the centromeric domain of Cen11, which is composed exclusively of centromeric satellite DNA, is hypomethylated compared with the pericentromeric domains. Thus, the DNA sequences associated with functional centromeres can be either hypomethylated or hypermethylated. The methylation patterns of centromeric DNA appear to be correlated with the composition of the associated DNA sequences. We propose that both hypomethylation and hypermethylation of CENH3-associated DNA sequences can serve as epigenetic marks to distinguish where CENH3 deposition will occur within the surrounding H3 chromatin.

  14. Deriving stellar inclination of slow rotators using stellar activity

    CERN Document Server

    Dumusque, X

    2014-01-01

    Stellar inclination is an important parameter for many astrophysical studies. Although different techniques allow us to estimate stellar inclinationt for fast rotators, it becomes much more difficult when stars are rotating slower than $\\sim2$-2.5 \\kms. By using the new activity simulation SOAP 2.0 that can reproduce the photometric and spectroscopic variations induced by stellar activity, we are able to fit observations of solar-type stars and derive their inclination. For HD189733, we estimate the stellar inclination to be $i=84^{+6}_{-20}$ degrees, which implies a star-planet obliquity of $\\psi=4^{+18}_{-4}$ considering previous measurements of the spin-orbit angle. For $\\alpha$ Cen B, we derive an inclination of $i=45^{+9}_{-19}$, which implies that the rotational spin of the star is not aligned with the orbital spin of the $\\alpha$ Cen binary system. In addition, assuming that $\\alpha$ Cen Bb is aligned with its host star, no transit would occur. The inclination of $\\alpha$ Cen B can be measured using 40...
