    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.

    Highlights: • The electronic structure of CeN is studied within the GGA+DMFT approach using SPTF and Hubbard I approximation. • 4f spectral functions from SPTF and Hubbard I are coupled to explain the various spectroscopic manifestations of CeN. • The calculated XPS and BIS spectra show good agreement with the corresponding experimental spectra. • The contribution of the various l-states and the importance of cross-sections for the photoemission process are analyzed. - Abstract: We have studied in detail the electronic structure of CeN including spin orbit coupling (SOC) and electron–electron interaction, within the dynamical mean-field theory combined with density-functional theory in generalized gradient approximation (GGA+DMFT). The effective impurity problem has been solved through the spin-polarized T-matrix fluctuation-exchange (SPTF) solver and the Hubbard I approximation (HIA). The calculated l-projected atomic partial densities of states and the converged potential were used to obtain the X-ray-photoemission-spectra (XPS) and Bremstrahlung Isochromat spectra (BIS). Following the spirit of Gunnarsson–Schonhammer model, we have coupled the SPTF and HIA 4f spectral functions to explain the various spectroscopic manifestations of CeN. Our computed spectra in such a coupled scheme explain the experimental data remarkably well, establishing the validity of our theoretical model in analyzing the electronic structure of CeN. The contribution of the various l-states in the total spectra and the importance of cross sections are also analyzed in detail.

    2008-01-01

    We infer from different seismic observations the energy supplied per unit of time by turbulent convection to the acoustic modes of Alpha Cen A (HD 128620), a star which is similar but not identical to the Sun. The inferred rates of energy supplied to the modes (i.e. mode excitation rates) are found to be significantly larger than in the Sun. They are compared with those computed with an excitation model that includes two sources of driving, the Reynolds stress contribution and the advection of entropy fluctuations. The model also uses a closure model, the Closure Model with Plumes (CMP hereafter), that takes the asymmetry between the up- and down-flows (i.e. the granules and plumes, respectively) into account. Different prescriptions for the eddy-time correlation function are also confronted to observational data. Calculations based on a Gaussian eddy-time correlation underestimate excitation rates compared with the values derived from observations for Alpha Cen A. On the other hand, calculations based on a L...

  10. MUSE discovers perpendicular arcs in Cen A inner filament

    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...

  11. The Hard X-ray Emission of Cen A

    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 ...

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.

    We have conducted a survey for wide common proper motion companions to 512 members of the Upper Cen-Lup (UCL) and Lower Cen-Cru (LCC) subgroups of the Sco-Cen OB association using astrometry and photometry from the SPM4 catalog. Companion candidates were selected within 3 arcminutes (23 kau = 0.11 pc at d = 130 pc). We find that 12% of the Sco-Cen members have stellar companions in the separation range 3-20 kau. Optical spectra of 16 candidate companions were taken with the new COSMOS spectrograph on the Blanco 4-m telescope and the Wide Field Spectrograph on the Australian National University 2.3-m telescope. The spectroscopic survey yielded 14 M-type stars with Na I surface gravity index indicative of pre-MS status, of which half were Li-rich (along with two background giant interlopers). Seven stars in the range M1-M4.5 appear to be Li depleted, but otherwise seem to be pre-MS due to their chromospheric activity, low surface gravity via the Na I index, and their co- movement with other young stars in Sco-Cen. We suggest that these stars represent the Li depletion boundary for UCL and LCC.

  16. 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.

    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.

  19. 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...

    Thanks to its thorough experience in the field of nuclear science and technology, its innovative research and the availability of large and unique nuclear installations, SCK.CEN is not only a renowned nuclear research institution, but also an important partner for nuclear education and training in Belgium as well as at international level. Within the SCK.CEN Academy, more than 60 years of nuclear expertise and experience gained from our different research projects is collected and transferred. In the interest of maintaining a competent workforce in industry, Healthcare, research, and policy, and of transferring nuclear knowledge and skills to the next generations, the SCK.CEN Academy takes it as its mission to: - provide guidance for students and early-stage researchers; - organize academic courses and customized training for professionals; - offer policy support with regard to education and training matters; - care for critical-intellectual capacities for society. Specifically in the domain of nuclear instrumentation the SCK.CEN Academy provides an opportunity to students at Bachelor, Master and PhD level to make use of the SCK.CEN infrastructure to support their thesis research or to perform an internship with the aim to improve and extend their knowledge and skills in a specific research or technical domain. Further, they can contribute to new findings in the field of nuclear instrumentation. The students are guided by our scientists, engineers and technicians who have years of experience in the relevant field. In addition, the SCK.CEN Academy contributes to traditional university education programs and delivers courses in several nuclear topics such as dosimetry. We also coordinate the Belgian Nuclear higher Engineering Network (BNEN), a one year (60 ECTS) master-after-master specialization in nuclear engineering in which 6 Belgian universities and SCK.CEN are involved. Beyond the contributions to academic education, we also provide several customized training

    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. Including overshooting also leads to the possibility of a convective core mostly sustained by the ppII chain energy output. We finally show that roughly 30\\% of the stellar models de...

  4. The Hard X-Ray Continuum of Cen A Observed With INTEGRAL SPI

    Burke, Mark J.; Jourdain, Elisabeth; Roques, Jean-Pierre; Evans, Daniel A.

    2014-05-01

    We revisit the average hard X-ray spectrum from the active galactic nucleus (AGN) of Centaurus A (Cen A) using 10 yr worth of observations with INTEGRAL SPI. This source has the highest flux observed from any AGNs in the SPI bandpass (23 keV-8 MeV). The 10 year light curve of Cen A is presented, and hardness ratios confirm that the spectral shape changes very little despite the luminosity varying by a factor of a few. Primarily, we establish the presence of a reflection component in the average spectrum by demonstrating an excess between 20 and 60 keV, from extending the spectral shape observed at low energy to the SPI regime. The excess in Chandra HETGS and INTEGRAL SPI data is well described by reflection of the dominant power-law spectrum from a neutral, optically thick atmosphere. We find that the reprocessed emission contributes 20%-25% of the 23-100 keV flux. The existence of a cutoff at tens to hundreds of kiloelectron volts remains controversial. Using simulated spectra, we demonstrate that a high energy cutoff reproduces the observed spectral properties of Cen A more readily than a simple power law. However, we also show that such a cutoff is probably underestimated when neglecting (even modest) reflection, and for Cen A would be at energies >700 keV, with a confidence of >95%. This is atypically high for thermal Comptonizing plasmas observed in AGNs, and we propose that we are in fact modeling the more gradual change in spectral shape expected of synchrotron self-Compton spectra.

    2015-01-01

    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.

    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...

    High-quality astrometric, spectroscopic, interferometric and, importantly, asteroseismic observations are available for α 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 α Cen A has a probability of approximately 40 per cent of having a convective core. This probability drops to few per cent if one considers reduced rates for the 14N(p,γ)15O reaction. These convective cores have fractional radii less than 8 per cent when overshoot is neglected. Including overshooting also leads to the possibility of a convective core mostly sustained by the ppII chain energy output. We finally show that roughly 30 per cent of the stellar models describing α Cen A are in the subgiant regime.

    fixed paraffin embedded (FFPE) primary tumor tissue has been suggested as a predictive biomarker of the effect of irinotecan in the treatment of metastatic CRC. Quantification of TOP1 protein levels in FFPE tissue may be difficult and calls for alternative methods.We have recently reported on TOP1 FISH...... analyses on 50 FFPE primary CRC tissues. When compared with results from normal colorectal mucosa, 80 % of the tumors showed increased TOP1 gene copy number and 2/3 had increased TOP1/CEN-20 ratio. MATERIALS AND METHODS FFPE samples from 154 stage III CRC patients not receiving adjuvant chemotherapy were...... included. For each patient TOP1 gene copy number and CEN-20 reference number were determined in 60 nuclei from the malignant tumor by FISH using a TOP1/CEN-20 probe mix. Similarly, the TOP1 gene copy number and and CEN-20 reference number were dertermined in the normal colorectal mucosa in 105 of the 154...

    2014-01-01

    We revisit the average hard X-ray spectrum from the AGN of Centaurus A (Cen A) using ten years worth of observations with INTEGRAL SPI. This source has the highest flux observed from any AGN in the SPI bandpass (23 keV--8 MeV). The 10 year lightcurve of Cen A is presented, and hardness ratios confirm that the spectral shape changes very little despite the luminosity varying by a factor of a few. Primarily, we establish the presence of a reflection component in the average spectrum by demonstrating an excess between 20-60 keV, from extending the spectral shape observed at low energy to the SPI regime. The excess in Chandra HETGS and INTEGRAL SPI data is well described by reflection of the dominant power law spectrum from a neutral, optically-thick atmosphere. We find that the reprocessed emission contributes 20-25% of the 23-100 keV flux. The existence of a cut-off at tens to hundreds of keV remains controversial. Using simulated spectra, we demonstrate that a high energy cut off reproduces the observed spectr...

    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...

    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 ...

    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...

    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.

    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.

    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.

    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.

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

    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.

A full MCNP model of BR1 has been recently developed in order to complement the results that can be obtained from activation dosimetry. After a general presentation of the reactor, this paper pays particular attention to its standard {sup 235}U(n,f) fast neutron field MARK III. This irradiation field is a useful tool for integral measurements and for detector calibrations.

    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 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 ...

    2015-10-01

    Community detection is an important work for discovering the structure and features of complex networks. Many existing methods are sensitive to critical user-dependent parameters or time-consuming in practice. In this paper, we propose a novel label propagation algorithm, called CenLP (Centrality-based Label Propagation). The algorithm introduces a new function to measure the centrality of nodes quantitatively without any user interaction by calculating the local density and the similarity with higher density neighbors for each node. Based on the centrality of nodes, we present a new label propagation algorithm with specific update order and node preference to uncover communities in large-scale networks automatically without imposing any prior restriction. Experiments on both real-world and synthetic networks manifest our algorithm retains the simplicity, effectiveness, and scalability of the original label propagation algorithm and becomes more robust and accurate. Extensive experiments demonstrate the superior performance of our algorithm over the baseline methods. Moreover, our detailed experimental evaluation on real-world networks indicates that our algorithm can effectively measure the centrality of nodes in social networks.

    Chromospheres and coronae are common phenomena on solar-type stars. Understanding the heating of those layers requires the direct access to the relevant empirical data. In particular, the chromospheric temperature minimum, i.e. the region of the atmosphere where the temperature undergoes a reversal and starts increasing to reach values of the order of MK in the corona, can be observed directly in the far infrared and in the submillimetre spectral regime. In this paper we present the results of the observations obtained in those ranges of the solar twin α Cen A. Similar to the Sun, the far infrared emission of this star originates in the temperature minimum above the stellar photosphere. To our knowledge, this is the first time a temperature minimum has been directly measured on a main-sequence star other than the Sun. This contribution is a summary of the the results presented in ``α Centauri in the far infrared. First measurements of the temperature minimum of a star other than the Sun'' (Liseau et al 2013, A&A, 549, L7) based on results from the Herschel} Open Time Key Project DUNES and APEX/LABOCA observations.

    We present preliminary Sloan u',g'-band light curves for a sample of known RR Lyrae variables in the Galactic globular cluster Omega Cen. Results are based on the partial reduction of multi-band time series photometric data collected during six consecutive nights with the visitor instrument ULTRACAM mounted on the New Technology Telescope (La Silla, ESO). This facility allowed us to simultaneously observe in three different bands (Sloan u',g',r') a field of view of about 6x6 arcminutes. The telescope and the good seeing conditions allowed us to sample the light curves every 15 seconds. We ended up with a data set of about 6,000 images per night per filter, for a total of more than 200,000 images of the selected field. This data set allowed us to detect different kind of variables, such as RR-Lyraes, SX Phoenicis, eclipsing binaries, semi-regulars. More importantly, we were able for the first time to sample at high-frequency cluster RR Lyraes in the u',g'-band and to show in detail the pulsation phases across ...

    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 gamma 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 Gamma=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 ...

    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.

Los flujos observados y los índices espectrales de esta fuente son claramente distintos a los predichos por el modelo estándar de un viento estelar de una estrella masiva, y parecen ser consistentes con emisión térmica ópticamente delgada. Aquí investigamos la emisión libre-libre en radio-continuo de un viento estelar con parámetros de inyección dependientes del tiempo, los cuales tienen como resultado la formación de choques internos que se alejan de la estrella central. Aunque nuestro modelo es capaz de predecir los flujos observados y los índices espectrales de la fuente CEN 1a, ´este falla en explicar la variabilidad detectada en el régimen ópticamente delgado. Concluimos que la emisión observada tiene naturaleza compuesta, con contribuciones tanto térmica como no-térmica.

    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.

    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.

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.

    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.

Ocorre que existem poucas pesquisas que avaliem a efetividade desses estudos. Normalmente o que se encontra na literatura são atributos destinados a avaliar o documento de apresentação do cenário. Nesse sentido, uma abordagem possível é a distinção entre o conteúdo, ou seja, o produto cenário propriamente dito, e o processo que dá suporte à sua elaboração. Nesse contexto teórico, a pesquisa objetivou propor e aplicar um método para avaliar a maturidade do processo de cenários nas organizações. Em consequência, identificaram-se os componentes e subcomponentes principais do processo de cenários que permitam avaliá-los; definiram-se as métricas que indiquem os estágios de maturidade organizacional em cenários; e realizou-se um exercício de aplicação do método por meio de pesquisa a um conjunto de organizações brasileiras selecionadas. Como uma alternativa possível para basear o método proposto, foi utilizado o modelo de maturidade em gerenciamento de projetos (MMGP. Assim, empreendeu-se um estudo multimetodológico, qualitativo e interpretativo para a coleta e interpretação dos dados, constando de levantamento bibliográfico, entrevistas com expertises do meio acadêmico e uso de técnica de análise de conteúdo. Como resultado, obteve-se uma proposta de avaliação do processo de cenários nas organizações, na qual se consideraram as seguintes etapas: preparação, elaboração, produção do documento e utilização.

    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.

    2017-02-01

    The SoLid experiment intends to search for active-to-sterile anti-neutrino oscillations at a very short baseline from the SCK•CEN BR2 research reactor (Mol, Belgium). A novel detector approach to measure reactor anti-neutrinos was developed based on an innovative sandwich of composite polyvinyl-toluene and 6LiF:ZnS(Ag) scintillators. The system is highly segmented and read out by a network of wavelength shifting fibers and SiPM. High experimental sensitivity can be achieved compared to other standard technologies thanks to the combination of high granularity, good neutron-gamma discrimination using 6LiF:ZnS(Ag) scintillator and precise localisation of the Inverse Beta Decay products. This technology can be considered as a new generation of an anti-neutrino detector. This compact system requires limited passive shielding and relies on spatial topology to determine the different classes of backgrounds. We will describe the principle of detection and the detector design. Particular focus on the neutron discrimination will be made, as well as on the capability to use cosmic muons for channel equalisation and energy calibration. The performance of the first 288 kg SoLid module (SM1), based on the data taken at BR2 from February to September 2015, will be presented. We will conclude with the next phase, which will start in 2016, and the future plans of the experiment.

    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...

    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...

  16. 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...

    We analyze spectra of 18 stars belonging to the faintest subgiant branch in omega Centauri (the SGB-a), obtained with GIRAFFE@VLT at a resolution o R~17000 and a S/N ratio between 25 and 50. We measure abundances of Al, Ba, Ca, Fe, Ni, Si, and Ti and we find that these stars have =-0.73 +/- 0.14 dex, similarly to the corresponding red giant branch population (the RGB-a). We also measure =+0.40 +/- 0.16 dex, and =+0.87 +/- 0.23 dex, in general agreement with past studies. It is very interesting to note that we found a uniform Al abundance, =+0.32 +/- 0.14 dex, for all the 18 SGB-a stars analysed here, thus supporting past evidence that the usual (anti-)correlations are not present in this population, and suggesting a non globular cluster-like origin of this particular population. In the dwarf galaxy hypothesis for the formation of omega Cen, this population might be the best candidate for the field population of its putative parent galaxy, although some of its properties appear contradictory. It has also been ...

    Long term optical and near-infrared photometric and blue spectroscopic observations were obtained for QS Tel, V834 Cen, and BL Hyi. The optical light curves of all three polars displayed large magnitude changes during our observations. These same high/low state transitions were also apparent in near-infrared JHK photometry, though with decreased amplitude. The color of the polar with respect to its state was examined and found not to be a good indicator of the instantaneous state. During low to high state transitions, a nearly constant magnitude difference was observed in all three polars. This $\\Delta$m value was found to be consistent with the level expected to occur if accretion onto the white dwarf reached the Eddington luminosity during the high state. The high state Balmer decrement was measured for each star and used to estimate that the temperature of the emission line forming region was ~12,000K with N$_H$ near 12.8 dex. No relationship between the Balmer emission line strength and the white dwarf ma...

Este estudo objetivou caracterizar as experiências educacionais dos internos dentro de atividades em Atenção Primária, Secundária e Terciária à saúde, com vistas a otimizá-las. Inicialmente, foi descrita a criação de um estágio em atendimento secundário, antes inexistente na instituição, e avaliada a percepção dos alunos envolvidos. Posteriormente, foram caracterizados os atendimentos prestados pelos alunos em três cenários (primário, secundário e terciário durante 30 dias. A criação do estágio na Unidade de Pronto Atendimento foi bem recebida pelos alunos, que sentiram necessidade de investir mais carga horária neste cenário. Foram avaliadas 201 consultas realizadas por internos, sendo a maioria na Atenção Primária.

    2012-01-01

    We study a sample of 5 dwarf irregular galaxies in the CenA/M83 group, which are companions to the giant elliptical CenA. We aim at deriving their physical properties over their lifetime and compare them to those of dwarfs located in different environments. We use archival HST/ACS data and apply synthetic color-magnitude diagram fitting in order to reconstruct the past star formation activity of the target galaxies. The average star formation rate for the studied galaxies ranges from 10^{-3} up to \\sim 7x10^{-2} M_odot/yr, and their mean metallicities correlate with their luminosities (from [Fe/H]\\sim -1.4 up to \\sim -1.0). The form of the star formation histories varies across the sample, with quiescent periods alternating with intermittent enhancements in the star formation (from a few up to several times the average lifetime value). The dwarfs in this sample formed ~35% to ~60% of their stellar content prior to ~5 Gyr ago. The resulting star formation histories for the CenA companions are similar to those ...

    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...

    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, ...

    2006-01-01

    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...

    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.

  8. Oxygen dependence of metabolic fluxes and energy generation of Saccharomyces cerevisiae CEN.PK113-1A

    2008-07-01

    Full Text Available Abstract Background The yeast Saccharomyces cerevisiae is able to adjust to external oxygen availability by utilizing both respirative and fermentative metabolic modes. Adjusting the metabolic mode involves alteration of the intracellular metabolic fluxes that are determined by the cell's multilevel regulatory network. Oxygen is a major determinant of the physiology of S. cerevisiae but understanding of the oxygen dependence of intracellular flux distributions is still scarce. Results Metabolic flux distributions of S. cerevisiae CEN.PK113-1A growing in glucose-limited chemostat cultures at a dilution rate of 0.1 h-1 with 20.9%, 2.8%, 1.0%, 0.5% or 0.0% O2 in the inlet gas were quantified by 13C-MFA. Metabolic flux ratios from fractional [U-13C]glucose labelling experiments were used to solve the underdetermined MFA system of central carbon metabolism of S. cerevisiae. While ethanol production was observed already in 2.8% oxygen, only minor differences in the flux distribution were observed, compared to fully aerobic conditions. However, in 1.0% and 0.5% oxygen the respiratory rate was severely restricted, resulting in progressively reduced fluxes through the TCA cycle and the direction of major fluxes to the fermentative pathway. A redistribution of fluxes was observed in all branching points of central carbon metabolism. Yet only when oxygen provision was reduced to 0.5%, was the biomass yield exceeded by the yields of ethanol and CO2. Respirative ATP generation provided 59% of the ATP demand in fully aerobic conditions and still a substantial 25% in 0.5% oxygenation. An extensive redistribution of fluxes was observed in anaerobic conditions compared to all the aerobic conditions. Positive correlation between the transcriptional levels of metabolic enzymes and the corresponding fluxes in the different oxygenation conditions was found only in the respirative pathway. Conclusion 13C-constrained MFA enabled quantitative determination of

    De Bremaecker, Anne

    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).

    Aims: We add four warmer late-type supergiants to our previous spectro-interferometric studies of red giants and supergiants. Methods: We measure the near-continuum angular diameter, derive fundamental parameters, discuss the evolutionary stage, and study extended atmospheric atomic and molecular layers. Results: V766 Cen (=HR 5171 A) is found to be a high-luminosity (log L/L⊙ = 5.8 ± 0.4) source of effective temperature 4290 ± 760 K and radius 1490 ± 540 R⊙, located in the Hertzsprung-Russell (HR) diagram close to both the Hayashi limit and Eddington limit; this source is consistent with a 40 M⊙ evolutionary track without rotation and current mass 27-36 M⊙. V766 Cen exhibits Na i in emission arising from a shell of radius 1.5 RPhot and a photocenter displacement of about 0.1 RPhot. It shows strong extended molecular (CO) layers and a dusty circumstellar background component. The other three sources are found to have lower luminosities of about log L/L⊙ = 3.4-3.5, corresponding to 5-9 M⊙ evolutionary tracks. They cover effective temperatures of 3900 K to 5300 K and radii of 60-120 R⊙. They do not show extended molecular layers as observed for higher luminosity RSGs of our sample. BM Sco shows an unusually strong contribution by an over-resolved circumstellar dust component. Conclusions: V766 Cen is a red supergiant located close to the Hayashi limit instead of a yellow hypergiant already evolving back toward warmer effective temperatures as discussed in the literature. Our observations of the Na i line and the extended molecular layers suggest an optically thick pseudo-photosphere at about 1.5 RPhot at the onset of the wind. The stars σ Oph, BM Sco, and HD 206859 are more likely high-mass red giants instead of RSGs as implied by their luminosity class Ib. This leaves us with an unsampled locus in the HR diagram corresponding to luminosities log L/L⊙ 3.8-4.8 or masses 10-13 M⊙, possibly corresponding to the mass region where stars explode as

    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.

    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.

  18. Close stellar conjunctions of α Centauri A and B until 2050 . An mK = 7.8 star may enter the Einstein ring of α Cen A in 2028

    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

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

    2010-01-01

    We present near-infrared (NIR) broadband (0.80--2.42 $\\mu$m) spectroscopy of two low mass X-ray binaries: V404 Cyg and Cen X-4. One important parameter required in the determination of the mass of the compact objects in these systems is the binary inclination. We can determine the inclination by modeling the ellipsoidal modulations of the Roche-lobe filling donor star, but the contamination of the donor star light from other components of the binary, particularly the accretion disk, must be taken into account. To this end, we determined the donor star contribution to the infrared flux by comparing the spectra of V404 Cyg and Cen X-4 to those of various field K-stars of known spectral type. For V404 Cyg, we determined that the donor star has a spectral type of K3 III. We determined the fractional donor contribution to the NIR flux in the H- and K-bands as $0.98 \\pm .05$ and $0.97 \\pm .09$, respectively. We remodeled the H-band light curve from \\citet{sanwal1996} after correcting for the donor star contribution...

    Full Text Available The present paper is a commentary on the talks given by Torres and Álvaro and by Krüger regarding Brazilian Social Psychology in the international context. Starting with a brief contrast with the situation in Portugal, this commentary next approaches, in a synthetic way, questions that cut across social psychology in the international setting, namely, those related with the recurrent dichotomy individual/collective, the great advances in social neuroscience, the study of minorities, the scarcity of psychosocial research about colonialism, and lastly, contemporary issues of science and educational policy.Faz-se aqui um comentário às intervenções de Torres e Álvaro e de Krüger sobre a Psicologia Social brasileira no cenário internacional. Começando por estabelecer um breve contraste com a situação em Portugal, de seguida este comentário aborda, de forma sintética, questões transversais à psicologia social no cenário internacional, designadamente as que se relacionam com a recorrente dicotomia individual/coletivo, os enormes avanços na neurociência social, o estudo das minorias, a escassez de estudos psicossociais sobre o colonialismo e, por último, questões contemporâneas de política científica e de ensino.

    Fraija, N; Perez, M

    2012-01-01

    Recent detections of Fanaroff-Riley Class I AGNs by HESS, MAGIC, and VERITAS suggest that very-high-energy gamma-rays (VHE, E > 100 GeV) may not have a leptonic origin. We present a hadronic model to describe the TeV photons as the neutral pion decay resulting from pgamma and pp interactions. For the pgamma interaction, we assume that the target photons are produced by leptonic processes and apparent at the second spectral peak. For the pp interaction we consider as targets the thermal particle densities in the lobes. We show that this model can describe the TeV spectra of the radio galaxies NCG 1275, M87 and Cen A

    2016-01-01

    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...

    The rapid proper motion of the alpha Cen pair (3.7 arcsec/yr) and its location close to the galactic plane on a rich stellar background combine to make them excellent candidates for stellar conjunctions with distant stars. Adding new astrometry to archival data, we have refined the orbital parameters, barycentric proper motion and parallax of alpha Cen and compute its apparent trajectory on sky over the coming decades. We present a catalog of the expected close conjunctions until 2050. An exceptional event will take place in early May 2028, when alpha Cen A will come within 0.015 +/- 0.135 arcseconds 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 alpha Cen within at least the next three decades. With an angular diameter of LD = 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 th...

  12. Dark energy in the environments of the Local Group, the M 81 group, and the CenA group: the normalized Hubble diagram

    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.

    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...

The developmental cycle of maize was simulated with the Wang and Engel (WE model with genotype-dependent coefficients for the cultivar BRS Missões. The developmental cycle was divided into vegetative phase (from emergence to silking, and reproductive phase (from silking to physiological maturity. Twelve sowing dates throughout the year were considered, resulting in emergences on the day 15 of each month all year round. Climate scenarios used were synthetic time series of 100 years of current climate and with increase in mean air temperature of +1, +2, +3, +4, and +5, with symmetric and asymmetric increases in daily minimum and maximum temperatures. As temperature increased, the number of years in which crop was killed by frost decreased, indicating that if global warming will confirm, the growing season for maize grown in subtropical environment will be longer by the end of this century. Maize vegetative and reproductive development was delayed or hastened depending upon the emergence time of the year, and if the increase in air temperature is symmetric or asymmetric, indicating complex Genotype x Environment interactions and high vulnerability of maize development to climate change.O objetivo deste trabalho foi simular o desenvolvimento da cultura de milho em cenários de aumento de temperatura em Santa Maria, RS, Brasil.

    Full Text Available Os periódicos de qualidade do Brasil alcançaram, nos últimos anos, um notável avanço, com a crescente presença nos índices bibliográficos internacionais e na web, impulsionados principalmente pela comunicação de resultados de pesquisa de autores brasileiros das diferentes áreas do conhecimento e com uso diferenciado dos idiomas inglês e português. 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.

    Full Text Available O cenário internacional contemporâneo é caracterizado por uma multiplicidade de agentes e interesses, gerando uma complexa teia de relações econômicas, sociais e jurídicas. os desafios globais representados pelas inéditas relações exigem respostas rápidas e eficientes por parte do direito. Essa jornada em busca das soluções para os conflitos emergentes do plano internacional requer uma releitura do significado da divisão entre as esferas pública e privada do direito. Seja através do crescimento dos fundos soberanos de riqueza, que traz à luz uma série de novos paradigmas no campo econômico, sobretudo a convergência entre o papel do estado e o papel do investidor internacional; seja através do encontro entre a necessidade de proteção aos direitos humanos e a harmonização do sistema multilateral de comércio internacional; seja através das interseções entre a governança global e a tutela dos direitos difusos, o direito internacional certamente caminha para a convergência.The contemporary international scenario is characterized by a multiplicity of actors and interests, creating a complex web of economic, social and legal relationships. The challenges represented by these new relationships need rapid and efficient responses by law. This journey seeking the solutions to the conflicts arising from the international arena requires a reassessment of the meaning of the division between public and private spheres of law. Through the growth of sovereign wealth funds, which arises several new paradigms in the economic field, noticeably the convergence between the role of the state and the role of the international investor; through the encounter between the necessity to protect human rights and harmonize the multilateral international trade system, or through the intersections between global governance and the protection of diffuse rights, international law is certainly moving towards the convergence.

    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. O conhecimento gerado constitui um marco zero sobre aspectos sociais envolvendo a prática pesqueira na região estudada, e poderá subsidiar o gerenciamento dos recursos pesqueiros, garantindo a sustentabilidade.Las comunidades tradicionales localizadas al margen del Rio Madeira son influenciadas por su estrecha relación con la naturaleza y um conocimiento profundo de sus ciclos.

  8. 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 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.

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.

O estudo leva em consideração o estoque de recursos florestais e o saldo residual entre as emissões e capturas de carbono ou Greenhouse gas (GHG estimadas para cada país, em 2020 e em 2050, de acordo com os relatórios Special Report on Emission Scenarios (SRES A1B1 e A2B2. A pesquisa foi conduzida de forma multidisciplinar, envolvendo conceitos das áreas de biologia das mudanças climáticas, de energia, de geociência, de economia e da contabilidade. Esta última que foi utilizada para delimitar o objeto da pesquisa e servir de método, por meio da técnica Inquired Balance Sheet, para mensuração e classificação dos ativos, dos passivos e dos patrimônios líquidos ambientais. Selecionou-se uma amostra de sete países representantes do BRIC (Brasil, Rússia, Índia e China e de países desenvolvidos da América, Europa e Ásia (EUA, Alemanha e Japão.

    Eliane Vieira

    Full Text Available Considerando o volume e a velocidade da informação que permeia o ambiente organizacional, este artigo tem o objetivo de auxiliar no entendimento e na contextualização dessa informação, por meio da avaliação de lideranças, com o propósito de determinar a percepção da informação e da sua relevância no contexto organizacional. A informação é responsável por contribuir para que a tomada de decisão responda às expectativas da empresa. À luz da teoria proposta por Choo (2003, este artigo reafirma que a informação deve ser processada, visando a reduzir ou evitar a incerteza e apoiar as decisões organizacionais; para isso, a forma como é percebida é vital para que cumpra seu propósito. A metodologia adotada visa a responder às perguntas: "Como a informação é percebida no cenário organizacional?" e "Qual é a relevância da informação?". Trata-se de estudo de caso realizado em uma organização privada, multinacional, do segmento de reflorestamento. Nos resultados, foi possível inferir que os envolvidos possuem uma notável percepção da informação e da sua relevância, embora se tenha observado que, em algumas situações, existe a necessidade de melhorar o fluxo, as ferramentas e a gestão da informação, para que, no contexto organizacional, ela constitua um recurso para decisões efetivas. Identificou-se que a necessidade de informação e sua aquisição, armazenamento, produtos e serviços, uso e disseminação, seguindo o modelo de Choo, realçam a percepção da informação e sua relevância no cenário institucional. A continuidade do estudo sugere a mensuração do impacto e influência da informação e a ampliação da percepção sob a perspectiva de subordinados.

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

    The 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 formação de médicos capacitados para atuar na Atenção Primária à Saúde (APS, cujo intuitoé promover um aprendizado vinculado às necessidades reais de saúde da comunidade, tem sido tema de estudos no Brasil há alguns anos. Em 1975, a Faculdade de Medicina da UFMG (FM/UFMG inseriu seus estudantes em cenários de APS e atualmente busca ampliar essa inserção. Neste sentido, o objetivo desta pesquisa foi investigar a percepção dos estudantes do oitavo período da FM/UFMG sobre as atividades realizadas nos centros de saúde, tomando como referência as propostas do SUS para a APS. Trata-se de estudo qualitativo, que utilizou para a coleta de dados as técnicas de observação e grupos focais com estudantes de Medicina. A experiência de inserção na APS foi considerada válida e importante para a formação médica, contribuindo para construir uma nova visão do processo saúde- -doença e da organização do SUS. Conclui-se que é importante inserir os estudantes de Medicina na APS em seu processo de formação.

    Full Text Available Com base na revisão de literatura, o manuscrito analisa qualitativamente um futuro cenário para a cana-de-açúcar no Brasil, com base na tendência de expansão da cultura observada ao longo da última década, a conjuntura atual do setor e as projeções de mudanças climáticas globais regionalizadas para este século. O principal foco foi associar os resultados científicos sobre a fisiologia da cana-de-açúcar e suas respostas à elevação na concentração de dióxido de carbono atmosférico e eficiência de uso da água com as perspectivas socioeconômicas do setor canavieiro do Brasil. Prováveis efeitos sobre plantas daninhas, pragas e doenças da cana-de-açúcar, também foram abordados. 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

    Thermal neutron capture cross-sections and resonance integrals of 139La(n, γ)140La and 140Ce (n, γ)141Ce are measured with respect to reference reactions 197Au(n, γ)198Au and 55Mn(n, γ)56Mn using the neutron activation technique. Measurements are carried out using neutrons from an Am-Be source located inside a concrete bunker. Two different methods are used for determining self-shielding factors of activation foils as well as for finding the epithermal neutron spectrum shape factor. For 139 La with reference to 197 Au and 55 Mn the measured thermal cross sections are 9.24 ± 0.25 b and 9.28 ± 0.37 b, respectively, while the measured resonance integrals are 12.18 ± 0.67 b and 11.81 ± 0.94 b, respectively. For 140 Ce with reference to 197 Au and 55 Mn the measured thermal cross sections are 0.44 ± 0.01 b and 0.44 ± 0.02 b, respectively, while the measured resonance integrals are 0.55 ± 0.03 b and 0.54 ± 0.04 b, respectively. The present measurements are compared with earlier measurements and evaluations. Presently estimated values confirm the established 139La(n, γ)140La cross-sections. The presently measured thermal capture cross-section 140Ce(n, γ)141Ce , though lower than the evaluated data, is having higher accuracy compared to previous measurements with large uncertainties. The resonance integral measured is higher (like most previous measurements) than most evaluations requiring a revision of the evaluated data.

    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.

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. Não significando, no entanto, que a integralidade fora utilizada como um dos pilares norteadores destes documentos.

    Full Text Available Após situar a homoparentalidade no contexto das novas práticas sociais e médicas referentes à filiação e à reprodução, o artigo apresenta um cenário do debate francês atual sobre essa questão. 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". This presentation intends to dismantle the opposite arguments and demonstrates the legitimacy of the reasoning favorable to homosexual parenthood.

Descrição do caso: Pesquisa intervencionista, de caráter qualitativo descritivo, realizada em uma piscina adaptada do Núcleo de Atenção Médica Integrada (NAMI da Universidade de Fortaleza, Ceará, no período de março a maio de 2005. O sujeito do estudo foi uma criança do gênero feminino, de 10 anos de idade, com diagnóstico de Síndrome de Down. A coleta de dados teve como instrumentos um roteiro de anamnese, uma ficha de avaliação do desenvolvimento neuropsicomotor, além do diário de campo para registro das observações clínicas durante as sessões. Estas informações foram organizadas e analisadas com base no raciocínio clínico do terapeuta ocupacional e, em seguida, descritas como estudo de caso. Observou-se evolução no desenvolvimento das habilidades relacionadas ao esquema corporal, tais como percepção das partes finas do próprio corpo, partes amplas no corpo do outro, imitação de posições, culminando com participação mais ativa nas atividades da vida diária. Considerações Finais: Verificou-se a eficácia das atividades terapêuticas ocupacionais realizadas no ambiente aquático para o desenvolvimento do esquema corporal da criança em estudo. Isso pode ser útil para a realização de novas pesquisas sobre a temática – cuja literatura é escassa – e contribuindo para a crescente atualização das práticas da Terapia Ocupacional

O artigo revisita, entre outras, hipóteses como: a das relações pré-históricas e históricas entre as línguas do tronco Tupi e aquelas da família Karib (hipótese Tupi-Karib; Rodrigues 1985a, 2003b, 2007a; e a do relacionamento genético mais distante envolvendo Tupi, Karib e Macro-Jê (Rodrigues 1990, 2000a e 2007. Ao fazê-lo, busca mostrar caminhos que permitam testar a validade destas e de outras hipóteses, colocando em cena, consequentemente, a questão de seu valor científico e a verificação de seu papel no cenário dos estudos de línguas indígenas e de linguística histórica, sobretudo. Ao mesmo tempo, o artigo lança um olhar sobre os detalhes da argumentação de Rodrigues, da utilização consistente do método que sustenta diferentes trabalhos seus e que lhe permitiu levantar determinadas hipóteses e aperfeiçoá-las, quer com relação à classificação de determinadas línguas, quer com relação a estabelecimento de determinados agrupamentos genéticos e a reconstruções linguísticas, quer ainda com respeito ao fundamento fonético e fonológico de determinadas ideias avançadas – ideias essas que, possuindo consequências para o estudo da mudança linguística, repercutem sobre a própria teoria fonológica, por se caracterizarem por um olhar mais aberto para relações menos familiares (Rodrigues, 1981, 1986a e 2003c.

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. Durante as fases de desenvolvimento da cultura mais sensíveis ao défice de água no solo, as três modalidades de ensaio foram regadas de igual modo (nível de fornecimento de água igual ao valor de ETc.

Codes, norms and legislations used in Brazil are out of date, and in most cases those adopted for both poultry and swine production are based on international standards to meet trade requirements. This research aimed to study and describe an overall scenario of the standards, norms and legislations for animal welfare items applied to broiler and swine production: rearing, handling and transportation. The critical points of these items were identified in accordance to standards and current literature on animal welfare issues, effective on January 2008. The comparison was based on given scores varying from 1-5 (very bad to very good as function of the existence of standard norms and legislations for each country and/or economic block, and for each type of demand, as well as the level of adoption by producers. When compared to counterparts Brazil detained the lowest score for all types of demands, and its mean score of norms is lower (p Brasil é o maior exportador de carne e uma das mais recentes importantes demandas do mercado importador está em torno do bem-estar animal. Os padrões, normas e legislações usadas no país são desatualizadas e, em muitos casos, estas são seguidas na produção animal são baseadas em padrões internacionais, para seguir requisitos do comércio que não atendem necessariamente o esquema brasileiro de alojamento. Esta pesquisa objetivou estudar e descrever o cenário das normas e legislações para as seguintes exigências, aplicadas a produção de frango de corte e suínos: alojamento, manejo e transporte, para subsidiar normas adequadas aplicadas às condições nacionais. Os pontos críticos destes itens foram identificados de acordo com padrões, normas de bem-estar animal e com a literatura vigente até Janeiro de 2008. A comparação foi baseada em escores atribu

    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. Paradoxically, the consumption patterns demand for the expansion in the industrial production based on the exploitation of the non-renewable resources, which technological risks, especially from the petrochemical industry, have put difficulties on the risk control and health surveillance. The petroleum refining is an activity potentially damageable to the environment and human health, particularly to workers. The main objective of this study was to

Por meio das pesquisas produzidas isoladamente por estas instituições, buscou-se, após um intenso trabalho de diálogo entre os pesquisadores, elaborar um método para novas investigações. Ele foi construído a partir das argumentações teóricas que levaram o grupo a uma busca pela integração de pesquisas de diferentes áreas e subáreas do conhecimento, concretizando-se em um projeto de pesquisa interinstitucional. Agora inicia-se a realização dessas pesquisas, com apoio da FAPESP e FAPERJ, que terão dois anos de duração. As investigações estão voltadas para espaços urbanos e periurbanos em suas dimensões socioambientais relacionadas a: comportamento de variáveis climáticas nos espaços urbanos consolidados; avaliação da qualidade da cobertura vegetal nas florestas contíguas a áreas urbanizadas; avaliação de intervenções em áreas de alta vulnerabilidade; localização dos investimentos públicos em habitação e infraestrutura em espaços não edificados; dinâmica das águas urbanas e sua relação com o uso e ocupação do solo e legislação urbanística. O artigo discute as bases teóricas e propõe questões metodológicas aplicáveis a estudos comparativos para a realização de cenários futuros visando a adaptação dos espaços urbanos e periurbanos a mudanças climáticas em curso. O intercâmbio entre os pesquisadores permitiu um primeiro avanço tendo como resultado a construção de um método aqui apresentado. O objetivo do artigo é a apresentação da metodologia para ampliação do debate referente às questões teóricas e metodológicas envolvidas.

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.

Issues related to the articulation of PNAN and future National Policy on Food and Nutrition Security will be analyzed to demonstrate the convergence of agendas among the priorities for the guarantee of the SAN. The authors identify the potential of this field of action, from the current institutional setting, and the need for comprehensive solutions that address the complexity of food and nutrition in health.

    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.

    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.

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. The discussion analyzes the accomplishments of those associations and other voluntary actions also arisen in the 90s in Brazil. The necessity of anchoring to volunteer initiatives the perspective of circuit of exchange, proximity and reciprocity is highlighted in order to avoid relapses to merit actions which reactivate philanthropy and dependence is highlighted as a central conclusion.

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.

En cuanto a las estrategias, se verifico que se emplean principalmente clases con el apoyo de recursos bidimensionales, como películas, textos, mapas y búsqueda en internet. Las principales dificultades fueron la falta de formación específica con respecto a los contenidos de Astronomía, y el nivel de abstracción exigido por los contenidos. De modo general, esos indicadores convergen para los resultados ya encontrados en otros estudios, en el que las deficiencias de la formación inicial de los profesores, o incluso su ausencia, dificulta el adecuado abordaje de la Astronomía en las clases.

Além disso, são analisadas as projeções de precipitação para o cenário RCP8.5 para o século XXI. A avaliação é realizada utilizando-se os dados do Climatic Research Unit (CRU e a reanálise 20th Century Reanalysis V2 do National Oceanic and Atmospheric Administration (NOAA. Os modelos são classificados através de índices que indicam como os padrões de variação sazonal, interanual e decenal são representados. A avaliação apontou como melhores modelos para o NEB as rodadas do modelo CANESM, enquanto para a bacia do Prata, a rodada do modelo francês CNRM_CM5_r1i1p1. Já para a Amazônia, destacam-se as rodadas do modelo GISS-E2-R. Na região NEB, a maioria dos modelos mostra maiores impactos na pré-estação, porém divergem quanto ao sinal da anomalia. Na região Amazônica, os modelos sugerem maiores possibilidades de redução na precipitação, em até 20,5%,33,6 e 39,5% para os períodos de 2010 a 2039, 2040 a 2069 e 2070 a 2099, respectivamente. Na região do Prata, o conjunto dos modelos projeta poucas alterações no período de 2010 a 2039.

    Full Text Available As projeções populacionais para pequenas áreas, como municípios, distritos, bairros e unidades territoriais de planejamento, vêm sendo cada vez mais demandadas em projetos e atividades nos setores público e privado. A elaboração e o acompanhamento de Planos Diretores Urbanos e Planos Plurianuais de Investimento, a avaliação de impacto de grandes projetos urbanos e a alocação de recursos em processos de planejamento participativo são algumas das atividades que vêm sendo executadas em bases tecnicamente mais aprimoradas no país, requerendo estimativas e projeções populacionais para os municípios e suas subdivisões. Assim, este trabalho apresenta uma metodologia de projeção demográfica para pequenas áreas, como bairros, distritos ou sub-regiões de municípios, passível de aplicação no país, tendo em vista as limitações e confiabilidade da informação disponível na escala municipal. Apresenta-se inicialmente o modelo quantitativo, aqui denominado ProjPeq, que permite a especificação de parâmetros relacionados ao crescimento vegetativo e atratividade residencial de cada pequena área. Discute-se em seguida a importância da incorporação do conhecimento e opinião de técnicos e especialistas para especificação de hipóteses sobre o crescimento urbano-regional em cenários prospectivos.

    The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Centauri using Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE), the planet-finder instrument installed at the European Southern Observatory (ESO) Very Large Telescope (VLT) UT3, using its near-infrared modules, InfraRed Dual-band Imager and Spectrograph (IRDIS) and IFS. No planet was detected directly, but we set upper limits on the mass up to 7 au by exploiting the AMES-COND models. Our IFS observations reveal that no planet more massive than ∼6-7 MJup can be present within 1 au. The dual-band imaging camera IRDIS also enables us to probe larger separations than other techniques such as radial velocity or astrometry. We obtained mass limits of the order of 4 MJup at separations of 2 au or larger, representing the most stringent mass limits at separations larger than 5 au available at the moment. We also made an attempt to estimate the radius of possible planets around Proxima using the reflected light. Since the residual noise for the observations is dominated by photon noise and thermal background, longer exposures in good observing conditions could improve the achievable contrast limit further.

    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. It is best reproduced by models of a non-eccentric ring with an inclination of $80\\pm1^{\\circ}$, a position angle of $-93\\pm1^{\\circ}$, and a semi-major axis of $59\\pm3$ au. We also ...

    Full Text Available An approach to schooling failure, within the sphere of contemporary pathologies, requires placing the social relationships in a historical dimension, characteristic of an epoch. When we refer to the aphorism: the unconscious is the social (ASSOUN, 1994; we disengage ourselves from readings that place the individual versus society and think schooling failure to be the reflex of contingencies, historical transformations and unconscious determinations that carry the initials of the social symptom, which is structured as the reflection of discourse production dominant of the period. It is therefore necessary to place discourse and pedagogical practice, which emerged in the Modern era, in order to understand schooling failure, an expression that directly opposes the ideals expected of schooling in terms of excellence of the learning function. What truth is depicted from schooling failure if the symptom results from repressed truth? It refers to the return and insistence stemming from the destination that civilization confers to the discomfort lived by humans. Thus, schooling failure, the return of a truth, attaches itself to a historical contingency or belongs to present day pathologies, wherein, the ideal to transform and to better society with scientific progress and improvement of technique persist as conditions for liberty and happiness. The execution of such an assignment is aligned to a forged model that imprisons the child in a technical childhood. Finally, schooling failure, as it reveals subjective truth, insinuates itself into the wrong direction to social demands that impose equality and cut out expressions of singularity excluded from spaces established by the dominant discourse, which give priority to orthopedics forms in order to sustain the ideal of perfect men.

The survey aims to resolve the disks and detect planets responsible for the disk morphology.

Methods: 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. The disk emission was modeled with the GRaTeR code. Results: We resolve a ring-like structure that extends up to 450 mas ( 50 au) from the star in the IRDIS and IFS data. It is best reproduced by models of a non-eccentric ring with an inclination of 80 ± 1°, a position angle of -93 ± 1°, and a semi-major axis of 59 ± 3 au. We also detect an additional, but fainter, arc-like structure with a larger extension (0.65 arcsec) South of the ring that we model as a second belt of debris at 130 au. We detect ten candidate companions at separations ≥1''. We estimate the mass of putative perturbers responsible for the disk morphology and compare this to our detection limits. Additional data are needed to find those perturbers, and to relate our images to large-scale structures seen with HST/STIS.

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.

    Full Text Available De natureza teórica, este artigo tem por objetivo analisar desafios que se colocam à consolidação de um sistema de governança ambiental global. Considerando que a questão ambiental diz respeito a um bem público global, sobrepondo-se, pois, aos limites estabelecidos pelas fronteiras físicas dos Estados-Nação, é dada especial ênfase à análise das questões da participação e da fragmentação da estrutura organizacional do sistema de governança transnacional em vigor atualmente. Para tal, questiona-se em que medida a estrutura criada sob a égide da ONU viabiliza a expressão democrática dos diferentes interesses envolvidos. Após consulta a importantes publicações sobre o tema, a conclusão a qual se chega, apoiada em Hermet (2005 e Kazancigil (2005, é a de que, para fugir da tendência à concentração do poder em grupos que defendem interesses particulares, seria necessário reafirmar a soberania e a legitimidade do campo político.

    table1.dat lists the background sources identified on deep CCD images of the close environment of Alpha Centauri (up to approximately 2.5'). Our VRIZ photometry has been complemented by JHK photometry extracted from the corresponding 2MASS images (Skrutskie et al., 2006AJ....131.1163S). This catalogue is particularly intended to provide a reference for future searches for faint companions of Alpha Centauri. Unavailable values are replaced by 99.00 in the table. We have revised the coordinates of the catalogue published in 2007. They are now much more consistent with reference astrometric catalogues such as 2MASS (Cat. II/246). There was a shift of typically 2 arcseconds between the 2MASS and SUSI2 coordinates, and now this is reduced to less than 0.5 arcsecond. We have also recomputed the photometric magnitudes using more accurate aperture corrections and instrument zero points The new version of the table is available on 13-Jun-2016, in place of the old one, in Vizier.

All the stars have a B magnitude brighter than 16.5. The median error is less than 2km/s. The stars are numbered using their LID (Leiden Identification Number) from van Leeuwen et.al. (2000, Cat. ). In a companion paper by van de Ven et al. (2006A&A...445..513V), we correct these radial velocities for the perspective rotation caused by the space motion of the cluster. Additionaly 339 stars where measured. These consist of (i) 87 stars with B-Vii) 252 stars not in the van Leeuwen et al. catalog.

    It is realized a study of the corrosion process and the products formed over the carbon steel in different points of the machine-room of the Electronuclear plant of Juragua (Cuba) particularly in the pipelines considering the specific characteristics of corrosion under roof which has been less studied. The determination of corrosiveness grade was carried out by gravimetric methods (lost and gain weight) in the different coats of the machine-room not existing a correlation between them in according to results with those ones obtained by Infrared Spectroscopy, in which there is not a correlation between the band intensities (lepidocrocite/ goethite) and the corrosion; however both explain different parts of corrosive process. Also it is realized the corrosion products analysis by chemical methods and by Atomic Absorption Spectrometry, obtaining the concentration of the major anions and cations of importance for the corrosion, not existing a meaning correlation between them and the corrosion velocity by what it was determined the absorption isotherms, obtaining as result a microporous structure in the formed oxides which was capable to retain and to absorb water and pollutants which could be this the main cause of corrosion. By analyzing the high concentration of iron and the low concentration of the remainder anions and cations it is possible to make the traditional chemical washes which are less expensive and greater effectiveness. All the obtained results are very important to assure the conditions of the pipelines systems installed at the presence of Government and Foreign organizations which are interested for the protection and conservation measures in the pipelines system.

    Full Text Available Buscamos neste trabalho apresentar os resultados de uma estratégia didática para o ensino de astronomia, sob a forma de oficina, desenvolvida junto a estudantes do ensino fundamental de uma Escola Família Agrícola do semiárido baiano, tendo como foco as narrativas míticas das constelações, de modo a avaliar como estas podem contribuir para uma melhor compreensão de noções que envolvem as constelações e estações do ano. Por meio desta oficina, foi possível desenvolver noções importantes sobre as estações do ano e suas relações com as constelações, ampliando os conhecimentos apresentados nos livros didáticos, distantes da realidade dos estudantes. O recurso às narrativas míticas pareceu facilitar a apreensão dos diversos significados conferidos às constelações, até então desconhecidos pelos estudantes.

    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.  .

  15. The genetic diversity of cen-tral and peripheral popula-tions of ratlike hamster(Cricetulus triton)

    Institute of Scientific and Technical Information of China (English)

    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.

    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.

    Full Text Available Com a intensa produção e veiculação de informações científicas, tornou-se difícil para o profissional médico manter-se atualizado com os recursos habituais. A necessidade de conhecer e de participar de processos de formação continuada se impõe. Entre outras iniciativas, a Associação Médica Brasileira e o Conselho Federal de Medicina lançaram o Programa Nacional de Educação Continuada a Distância para médicos, buscando divulgar o conhecimento produzido nos grandes centros para profissionais de áreas mais remotas ou com reduzida disponibilidade de tempo. Tendo como pressu posto que a Sociedade do Conhecimento requer a formação inicial e continuada de profissionais e de cidadãos com um novo conjunto de competências para atuar com eficiência e responsabilidade, esses programas devem ser desenvolvidos com base em abordagens pedagógicas que efetivamente valorizem, além dos conteúdos de ensino, a disposição para a pesquisa, a autonomia na busca da informação, o espírito colaborativo e a postura ética, entre outras. No intuito de contribuir para essa reflexão, este texto tem por objetivos retomar o processo de formalização da educação médica continuada a distância no Brasil em termos didático-pedagógicos e analisar perspectivas dessas ações educativas.

    2007-01-01

    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 A economia do Estado de Mato Grosso, mais acentuadamente nos dez últimos anos, vem experimentando significativas mutações na sua estrutura produtiva, dado que a tradicional base econômica primária está se consolidando como moderna produção agroindustrial. Como causa da abertura comercial decorrente da globalização das economias surgem e/ou se fortalecem inexploradas ligações diretas com o exterior que enfraquecem a unilateralidade das vinculações com a região Sudeste, estruturada no mercado interno. Nesta análise, dedica-se especial atenção às vias de transportes na integração da economia do Estado com a economia nacional e internacional, além das mudanças nas especificidades da interação entre alguns dos seus principais núcleos urbanos.

Por meio da análise e reflexão, constatamos que o Município de Inhambane, Moçambique, apresenta potencial turístico a partir da combinação única das condições do seu litoral – o qual dispõe de uma faixa de areia, condições únicas para a prática de mergulho, pesca desportiva –, com a herança árabe e colonial portuguesa presente na sua cidade antiga, ambos associados à beleza paisagística do patrimônio natural ali presente. Ao refletirmos sobre a importância do patrimônio cultural na diversificação da oferta turística, em atividades complementares e/ou substitutas às tradicionais formas de Turismo, observamos que por meio da [re]ativação deste patrimônio, quase desconhecido dos turistas e das instituições culturais locais, sugerimos que o município pode de forma sustentável [re]apropriar-se e se reconstituir, [re]produzir-se e ser consumido por novas tipologias de Turismo emergente/alternativo, ávidas pela utilização do patrimônio cultural, e não só pelo desfrute do tradicional Turismo de sol e mar, já presente neste município.   Cultural Heritage and Tourism: Setups for the Inhambane Municipality in Mozambique – This article goes through the relationships that can be established between cultural heritage and Tourism, in order to [re]organize the tourist places once constituted almost exclusively by the influence of the natural heritage components.

    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.

    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 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].

    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 Inúmeras são as atividades agrícolas que necessitam de interação humana nos processos decisórios, e entre elas encontra-se a classificação de frutos. O consumo de frutos "in natura" exige altíssimo nível de qualidade, demandando um processo classificatório mais acurado. A classificação de frutos depende do reconhecimento de padrões natural ou artificial, de acordo com algumas categorias pré-definidas. Uma vez que um padrão de um fruto está sendo classificado, esse deve ser comparado com algum outro padrão armazenado. A maior parte da classificação de frutos é baseada na classificação humana.Este trabalho apresenta a possibilidade de uso de redes neurais artificiais no desenvolvimento de modelos de classificação de frutos por meio de vetores de padrões. Este trabalho foi desenvolvido no Departamento de Máquinas Agrícolas da Faculdade de Engenharia Agrícola da Universidade Estadual de Campinas, as redes neurais armazenaram os vetores de padrões de frutos peso, diâmetro. Esses componentes vetoriais associados entre si interagiram, determinando um vetor padrão de saída de acordo com os padrões de frutos armazenados. Para atingir esses objetivos, foi usada uma rede Perceptron de múltiplas camadas, com algoritmo de treinamento tipo retro-propagação para armazenar os vetores de padrões de frutos e para classificação desses padrões de entrada. A rede treinada conseguiu aprender a relação entre vetores de entrada e saída, demonstrando a potencialidade do uso de tais ferramentas na classificação artificial.Agriculture is one of the economic activities that more require the presence human being in the decision taking. Innumerable are the processes that require some type of human being interference in the conclusion of the processes. Fruit Sorting depends on human or artificial pattern recognition according to some pre defined categories. Once a fruit pattern is under classification, this one must be compared to some other ones stored. After that comparison it can be classified. Most sorting fruits jobs are human basis classification. This paper shows that using neural networks is possible to develop capable models of storing fruit pattern vectors. Given any fruit pattern vector to the model it can classify to the closest fruit pattern vector stored. The number of patterns were incremented and presented to the neural networks, classifying the presented fruits and proved the scalability of number of vector components used in fruit pattern vectors stored in the model. This work was developed in the Agricultural Machinery Department of the Agricultural Faculty in State University of Campinas, the neural networks stored fruit pattern vectors such as Weight, Diameter. These vectors components associated itself interacted determining an output pattern vector classifying according to the stored fruit vector patterns. A Multi Layer Perceptron Network with Backpropagation algorithm was used, storing the relationship between input fruit pattern vectors and output classification class vectors. The neural network was trained and tested presenting the desired results, it can be used as a tool for future fruit classification processes.

    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.

    Full Text Available Este estudo empírico-analítico tem por objetivos promover uma comparação dos níveis de regulação da atividade de auditoria em instituições bancárias e avaliar a relação entre esse grau de regulação e características dos sistemas bancários nacionais. Utilizou-se uma base de dados mantida pelo Banco Mundial, contendo pesquisa realizada junto a autoridades supervisoras e regulatórias bancárias nacionais de 172 países. Por meio de estatísticas descritivas, foi constatado que o nível mais elevado de regulação é registrado nas nações mais desenvolvidas e nos países do Oriente Médio, Norte da África, Europa e Ásia Central. Também foi constatado que o Brasil apresenta grau de regulação superior à média verificada internacionalmente. Quanto aos testes realizados, por meio de regressão, para avaliar a relação entre o nível de regulação de auditoria e características do setor bancário, foi evidenciado que há mais requerimentos para a atuação dos auditores nos países em que o crédito doméstico provido pelo setor bancário é maior e onde os bancos são mais rentáveis. Por outro lado, há menor regulação nos países em que há maior participação de bancos estatais no sistema financeiro e onde há mais restrições à atuação das instituições bancárias. Não foi confirmada a hipótese de associação positiva entre grau de concentração do setor bancário e o nível de regulação da atividade de auditoria. Por fim, foi constatado que, em 2000, primeiro ano da pesquisa, o nível de regulação era menor que os níveis apurados nos demais exercícios, enquanto que, em 2007, último ano da pesquisa, o nível de regulação é maior que nos anos anteriores, confirmando o que foi encontrado na literatura de que as normas de auditoria tendem a se tornar mais rigorosas com o passar do tempo, na medida em que a demanda por requerimentos mais estritos se acumula, notadamente em momentos de crise de credibilidade.

Halbwachs (2006, entre otros autores, auxilia la articulación entre la memoria y el contexto sociohistórico reconstruido desde la perspectiva de la historia cultural. El conjunto de indicadores empíricos evidencia un conocimiento integrado al hacer docente en aquella comunidad y la movilización de la misma para que los hijos de los colonos tuvieran escuela. Al desarrollar los procedimientos analíticos se perciben, también, los límites y posibilidades en el uso de la memoria. Entre las conclusiones, la pregunta continúa siendo: un grupo escolar en una región rural germánica podría estar asociado a la “política de nacionalización” que caracterizó el gobierno de Getúlio Vargas?

    Full Text Available O presente artigo possui como objetivo apresentar uma perspectiva das relações internacionais onde novos atores adentram aos processos diplomáticos, até então exclusivos das interações entre Estados-Nação. Na paradiplomacia, o Subnacional (regiões, estados federais e municípios, organizações e sociedade civil começam a dividir espaços antes restritos às governanças, auxiliando o desenvolvimento de políticas públicas. Com a crescente relevância dos estudos conceituais sobre Cultura, demonstra-se cada vez mais o papel importante que esta desempenha nas relações exteriores. Assim sendo, este trabalho terá como objetivo compreender as ações paradiplomáticas e qual a relevância da Cultura, em conjunto com a Teoria das Relações Internacionais, como instrumento de desenvolvimento para estas políticas. Observaremos ações políticas que ocorrem na zona de fronteira entre Brasil e Uruguai, para identificar as ações paradiplomáticas existentes.

    Full Text Available Este caso para ensino foi elaborado a partir dos problemas enfrentados pela DELTA, líder no mercado brasileiro de controle de pragas urbanas, a partir da epidemia de dengue do verão de 2007/2008, quando as vendas de inseticidas e repelentes pelos players do setor atingiram volumes significativamente superiores às expectativas. 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.

    Solid recovered fuels (SRF) are expected to fulfil an important role in Europe. At present no European standards are available for solid recovered fuels. To facilitate the use of these fuels, it is considered to be of key importance to develop standards for terminology, classification,chemical and physical characterisation, and quality management system. For this purpose a Technical Committee under supervision of the European Committee on Standardization is founded. In this framework the Energy Research Centre of the Netherlands (ECN) has represented the Netherlands in a working group on terminology and quality management systems. As a result of the joint effort of several European experts, Technical Specifications on these subjects have been developed. [Dutch] De doelstelling van het onderhavige project is het leveren van de Nederlandse bijdrage - door middel van het overdragen van informatie vanuit de Europese context naar de Nederlandse belanghebbenden en vice versa - aan de ontwikkeling van de terminologie- en kwaliteitsmanagement systeem norm (Quality Management System (QMS)) die onderdeel uitmaakt van de te ontwikkelen Europese normen voor kwaliteitsborging, classificatie en karakterisering van solid recovered fuels (SRF). Een dergelijk terminologiedocument, waarin definities en beschrijvingen van essentiele termen voorkomend in de verschillende deelnormen worden gegeven en het tweede onderdeel, een kwaliteitsmanagementsysteem, zijn vaste onderdelen van dit type normen. Gedurende de looptijd van dit project zullen deze documenten voor SRF worden uitgewerkt in een werkgroep bestaande uit Europese (afval)experts. De doelgroepen van deze norm zijn onder andere overheden, elektriciteitsproducenten, afvalproducenten, -verwerkers en -sorteerders, meetorganisaties en onderzoeksinstituten.

    Full Text Available No intuito de ordenar espaços e devolver aos centros urbanos o papel hegemônico perdido, políticas urbanas contemporâneas vêm procurando fomentar diferentes modos de intervenção designados por "revitalização" ou "requalificação". A cidade, voltada para a valorização de seu patrimônio histórico, torna-se então objeto de remodelações e reformas arquitetônicas, com vistas à preservação, ensejando imagens e marcas. Refletir sobre as intervenções em centros urbanos de metrópoles contemporâneas, incluindo experiências mais recentes realizadas em cidades nordestinas, constitui o objetivo central do presente artigo. Com menos interesse em fazer avaliações propositivas, o artigo analisa concepções e conflitos simbólicos que balizam práticas de "revitalização". A presença de consumidores variados do espaço público (turistas, moradores, comerciantes etc. e as polêmicas estabelecidas em torno dos investimentos culturais e econômicos servirão de baliza para as ideias presentes no texto.

    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.

    Full Text Available O presente trabalho tem por propósito refletir sobre o atual contexto da Educação Superior no Brasil, propiciando o conhecimento de diferentes aspectos que comprovam a importância da ética na formação universitária e a necessidade de contrapô-la à tecnificação do Ensino Superior. Para isso, no primeiro momento, são analisadas as transformações socioculturais ocorridas nas últimas décadas. A apresentação dessas transformações possibilita conhecer as atuais tendências da Educação Superior a partir do processo de globalização, da urbanização, do predomínio do conhecimento e da internacionalização da educação. Com a passagem da "sociedade do trabalho" para a "sociedade do conhecimento", influenciada pelo desenvolvimento das tecnologias da informação, iniciado em meados do século XX, o conhecimento tornou-se uma mercadoria altamente comercializável. A partir de então, os cursos superiores passaram a ser criados sob a ótica do mercado. A abertura do mercado educacional obteve respaldo na década de 1990, após a implementação de políticas educacionais de cunho neoliberal. Tais iniciativas proporcionaram expressivo aumento do número de IES particulares ou privado/mercantis. Ao compreender essa nova dinâmica que configura o mundo contemporâneo e a influência das políticas públicas no âmbito educacional, são apresentadas as consequências do processo de mercantilização do Ensino Superior e os desafios a serem enfrentados pela Universidade.The purpose of this work is to reflect on the current context of higher education in Brazil, providing knowledge of different aspects that prove the importance of ethics in university education and the need to contrast it to the technological development of higher education. For this, at first, we analyze the socio-cultural transformations that occurred in recent decades. The presentation of these transformations makes it possible to know the current trends in higher education from the process of globalization, urbanization, the prevalence of knowledge and internationalization of education. With the passage from the “society of work” to the “knowledge society”, influenced by the development of information technology, started in the mid-twentieth century, knowledge has become a highly marketable commodity. Since then, higher education majors began to be created from the perspective of the market. The opening of the educational market got support in the 1990s, after the implementation of neoliberal educational policies. These initiatives have provided a significant increase in the number of private or private/ commercial HEIs. By understanding this new dynamic that shapes the contemporary world and the influence of public policies in education, this work presents the consequences of the process of commodification of higher education and the challenges faced by universities.

As técnicas de pesquisa conjugaram abordagens quantitativa e qualitativa, com uso de modelo lógico e matriz de julgamento. O componente quantitativo utilizou dados do Sistema de Informação de Agravos de Notificação e dados populacionais do Departamento de Informática do Sistema Único de Saúde. As variáveis foram, idade, sexo, forma clínica, procedência, tipo de entrada, meios diagnósticos e situação de encerramento. Para a população foram feitos cálculos de interpolação geométrica, por faixa etária, sexo e procedência (urbana e rural. O componente qualitativo combinou técnicas e fontes: pesquisa documental; observação e entrevista. O modelo lógico propiciou o entendimento da estrutura, processo e resultado do PCT; e a matriz de julgamento permitiu identificar o grau de implantação. A taxa média de incidência da tuberculose na área urbana foi 27 casos por 100.000 habitantes e de 9,4 por 100.000 habitantes na área rural, com razão masculino/feminino de 1,6. A avaliação do contexto externo, vigilância epidemiológica e operacionalização do PCT mostrou grau de implantação intermediário. No contexto organizacional, estrutura física das Unidades Saúde, recursos humanos e efetividade, o resultado foi incipiente. No geral, o grau de implantação foi intermediário. A flutuação nas notificações e taxas anuais de incidência, associada ao não cumprimento das metas do PCT, à desarticulação entre o PCT e o restante da atenção básica e à não interiorização da assistência indicam sérias dificuldades na operacionalização das ações de controle da tuberculose.This is an evaluative research, a type of study case of the context and degree of implementation of the Tuberculosis Control Program (PCT in the city of Coari, State of Amazonas, 2001-2008. Research techniques combined quantitative and qualitative approaches, using a logical model and a judgment matrix. The quantitative component used data from the Information System for Notifiable Diseases and Population Data from the Department of the Brazilian National Health System. The variables assessed were age, sex, clinical form, origin area, type of entry, diagnostic and outcome. For population there were calculated geometric interpolation, by age, gender and residence (urban or rural. The qualitative component combined techniques and sources: documentary research and observation and interview. The logical model led to the understanding of the structure, process and outcome of the PCT, and with the judgment matrix we identified the degree of implementation. The mean tuberculosis incidence was 27 cases per 100.000 inhabitants in urban area, and 9.4 per 100,000 in rural area, with a male / female ratio of 1.6. The external context assessment, surveillance and operation of the PCT showed intermediate degree of implementation. In the organizational context, the physical structure of the Health Units, human resources and effectiveness, the result was incipient. In general, the level of implementation was intermediate. Oscillations in notifications and annual rates of incidence indicate serious difficulties in the actions of the tuberculosis control. These difficulties are also associated with non-compliance with the goals of the PCT, disconnection between the PCT and the primary health care and absence of health care polices for the interior population.

    Full Text Available A Amazônia Legal foi alvo de políticas desenvolvimentistas no século XX. Com características estruturais diferentes dasdo restante do Brasil e abrigando a maior floresta tropical do mundo, o resultado foi crescimento econômico e desmatamento. Alguns fatores são apontados como determinantes desse desmatamento, como as políticas de incentivo ao desenvolvimento das décadas de 1970 e 1980, os investimentos em infraestrutura, a pecuária e a agricultura. Este artigo apresenta uma metodologia de projeção para o desmatamento nas mesorregiões da Amazônia Legal, decorrente de fatores econômicos e de condicionantes estruturais da região. Para isso, foi usado um modelo de Equilíbrio Geral Computável (EGC dinâmico inter-regional com uma especificação para a ocupação do solo nas regiões, isto é,uma inovação para a literatura.Os resultados para o período estudado(2006-2030 apontaram que as regiões com maior crescimento e desmatamento seriam aquelas situadas no arco do desmatamento(Mato Grosso, Pará e Rondônia, principalmente regiões produtoras de soja e bovinos.

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.

    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.

The project was based on the complementary approach put forth by Murcia and Jaramillo, backed by Schutz's social-hermeneutic phenomenology and social imaginaries as support theory. The design featured three stages. The first involved an approach to reality, which is defined as a scheme of social intelligibility; the second defined the plan for gathering information and delving into each of the categories of the scheme, using the actors themselves as the crux; while the third focused on constructing the sense or meaning through triangulation of the information. The results highlight the fact that dance articulates the corporeality/motor skill technique in a symphony of recognition of others and oneself.

    Exploration into morphofunctional organisation of centromere DNA sequences is important for understanding the mechanisms of kinetochore specification and assembly. In-depth epigenetic analysis of DNA fragments associated with centromeric nucleosome proteins has demonstrated unique features of centromere organisation in chicken karyotype: there are both mature centromeres, which comprise chromosome-specific homogeneous arrays of tandem repeats, and recently evolved primitive centromeres, which consist of non-tandemly organised DNA sequences. In this work, we describe the arrangement and transcriptional activity of chicken centromere repeats for Cen1, Cen2, Cen3, Cen4, Cen7, Cen8, and Cen11 and non-repetitive centromere sequences of chromosomes 5, 27, and Z using highly elongated lampbrush chromosomes, which are characteristic of the diplotene stage of oogenesis. The degree of chromatin packaging and fine spatial organisations of tandemly repetitive and non-tandemly repetitive centromeric sequences significantly differ at the lampbrush stage. Using DNA/RNA FISH, we have demonstrated that during the lampbrush stage, DNA sequences are transcribed within the centromere regions of chromosomes that lack centromere-specific tandem repeats. In contrast, chromosome-specific centromeric repeats Cen1, Cen2, Cen3, Cen4, Cen7, Cen8, and Cen11 do not demonstrate any transcriptional activity during the lampbrush stage. In addition, we found that CNM repeat cluster localises adjacent to non-repetitive centromeric sequences in chicken microchromosome 27 indicating that centromere region in this chromosome is repeat-rich. Cross-species FISH allowed localisation of the sequences homologous to centromeric DNA of chicken chromosomes 5 and 27 in centromere regions of quail orthologous chromosomes.

    with metastatic colorectal cancer. METHODS: From a national cohort, we identified 163 patients treated every third week with irinotecan 350 mg/m(2) as second-line therapy. Among these 108 were eligible for analyses and thus entered the study. Primary tumors samples were collected and tissue microarray (TMA......) blocks were produced. FISH analysis was performed using two probe-mixes: TOP1/CEN-20 and TOP1/CEN-2. Only samples harboring all three signals (TOP1, CEN-20 and CEN-2) using FISH were included in the analyses. RESULTS: In the TOP1/CEN-20 probe-mix the median TOP1- and CEN-20 CN were 4.46 (range: 1.......5-9.5) and 2.00 (range: 0.55-4.55), respectively. The median TOP1- and CEN-2 CN in the TOP1/CEN-2 probe-mix, were 4.57 (range: 1.82-10.43) and 1.98 (range: 1.22-6.14), respectively.

    Centromeric (CEN) chromatin is placed under mechanical tension and stretches as kinetochores biorient on the mitotic spindle. This deformation could conceivably provide a readout of biorientation to error correction mechanisms that monitor kinetochore–spindle interactions, but whether CEN chromatin acts in a tensiometer capacity is unresolved. Here, we report observations linking yeast Topoisomerase II (Top2) to both CEN mechanics and assessment of interkinetochore tension. First, in top2-4 a...

    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.

    Centromeric (CEN) chromatin is placed under mechanical tension and stretches as kinetochores biorient on the mitotic spindle. This deformation could conceivably provide a readout of biorientation to error correction mechanisms that monitor kinetochore-spindle interactions, but whether CEN chromatin acts in a tensiometer capacity is unresolved. Here, we report observations linking yeast Topoisomerase II (Top2) to both CEN mechanics and assessment of interkinetochore tension. First, in top2-4 and sumoylation-resistant top2-SNM mutants CEN chromatin stretches extensively during biorientation, resulting in increased sister kinetochore separation and preanaphase spindle extension. Our data indicate increased CEN stretching corresponds with alterations to CEN topology induced in response to tension. Second, Top2 potentiates aspects of the tension checkpoint. Mutations affecting the Mtw1 kinetochore protein activate Ipl1 kinase to detach kinetochores and induce spindle checkpoint arrest. In mtw1top2-4 and mtw1top2-SNM mutants, however, kinetochores are resistant to detachment and checkpoint arrest is attenuated. For top2-SNM cells, CEN stretching and checkpoint attenuation occur even in the absence of catenation linking sister chromatids. In sum, Top2 seems to play a novel role in CEN compaction that is distinct from decatenation. Perturbations to this function may allow weakened kinetochores to stretch CENs in a manner that mimics tension or evades Ipl1 surveillance.

    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.

    Cut-off Grade Strategy (COGS) is a concept that directly influences the financial, technical, economic, environmental, and legal issues in relation to exploitation of a mineral resource. A decision making system is proposed to select the best technically feasible COGS under price uncertainty. In the proposed system both the conventional discounted cash flow and modern simulation based real option valuations are used to evaluate the alternative strategies. Then the conventional expected value criterion and a multiple criteria ranking system were used to rank the strategies based on the two valuation methods. In the multiple criteria ranking system besides the expected value other stochastic orders expressing abilities of strategies in producing extra profits, minimizing losses and achieving the predefined goals of the exploitation strategy are considered. Finally, the best strategy is selected based on the overall average rank of strategies through all ranking systems. The proposed system was examined using the data of Sungun Copper Mine. To assess the merits of the alternatives better, ranking process was done at both high (prevailing economic condition) and low price conditions. Ranking results revealed that at different price conditions and valuation methods, different results would be obtained. It is concluded that these differences are due to the different behavior of the embedded option to close the mine early, which is more likely to be exercised under low price condition rather than high price condition. The proposed system would enhance the quality of decision making process by providing a more informative and certain platform for project evaluation.

    Characterization of normal age-related changes in resting state brain networks associated with working memory performance is a major prerequisite for studying neurodegenerative diseases. The aim of this study was to investigate the relationship between performing a working memory task (under MRI) and resting-state brain networks in a large cohort of healthy elderly subjects (n=337). Functional connectivity and interactions between networks were assessed within the default mode (DMN), salience (SN), and right and left central executive (CEN) networks in two groups of subjects classed by their performance (low and high). The low performance group showed lower functional connectivity in both the DMN and SN, and higher functional connectivity in the right and left CEN compared to the high performance group. Overall the functional connectivity within the DMN and the CEN were correlated. The lower functional connectivity within the DMN and SN in the low performance group is suggestive of altered attentional and memory processes and/or altered motivation. The higher functional connectivity within the CEN could be related to compensatory mechanisms, without which the subjects would have even lower performances. The correlation between the DMN and CEN suggests a modulation between the lower functional connectivity within the DMN and the higher functional connectivity within the CEN when performance is reduced. Finally, this study suggests that performance modifications in healthy elderly subjects are associated with reorganization of functional connectivity within the DMN, SN, and CEN.

    The clinical benefit of anthracyclines has been connected to HER2 status, TOP2A status and centromere 17 copy numbers (CEN-17). Data from a clinical trial randomizing patients to anthracyclines was used to assess whether the number of CEN-17 in breast cancers may predict incremental responsiveness...... to anthracyclines besides what is obtained when used relatively to TOP2A and HER2. As cut sections of paraffin-embedded tissue are prone to truncation of nuclei, strict definition of ploidy levels is lacking. We therefore used normal breast tissue to assist define ploidy levels in cut sections. Fluorescence in situ...... hybridization (FISH) with centromere 17 (CEN-17) and TOP2A was performed on 120 normal breast specimens. The diploid CEN-17 copy number was reduced from the expected two signals in whole nuclei to an average of 1.68 signals per nucleus in cut sections of normal breast. Ploidy levels determined in normal breast...

  9. Role of four conserved aspartic acid residues of EF-loops in the metal ion binding and in the self-assembly of ciliate Euplotes octocarinatus centrin.

    Ciliate Euplotes octocarinatus centrin (EoCen) is an EF-hand calcium-binding protein closely related to the prototypical calcium sensor protein calmodulin. Four mutants (D37K, D73K, D110K and D146K) were created firstly to elucidate the importance of the first aspartic acid residues (Asp37, Asp73, Asp110 and Asp146) in the beginning of the four EF-loops of EoCen. Aromatic-sensitized Tb(3+) fluorescence indicates that the aspartic acid residues are very important for the metal-binding of EoCen, except for Asp73 (in EF-loop II). Resonance light scattering (RLS) measurements for different metal ions (Ca(2+) and Tb(3+)) binding proteins suggest that the order of four conserved aspartic acid residues for contributing to the self-assembly of EoCen is Asp37 > Asp146 > Asp110 > Asp73. Cross-linking experiment also exhibits that Asp37 and Asp146 play critical role in the self-assembly of EoCen. Asp37, in site I, which is located in the N-terminal domain, plays the most important role in the metal ion-dependent self-assembly of EoCen, and there is cooperativity between N-terminal and C-terminal domain (especially the site IV). In addition, the dependence of Tb(3+) induced self-assembly of EoCen and the mutants on various factors, including ionic strength and pH, were characterized using RLS. Finally, 2-p-toluidinylnaphthalene-6-sulfonate (TNS) binding, ionic strength and pH control experiments indicate that in the process of EoCen self-assembly, molecular interactions are mediated by both electrostatic and hydrophobic forces, and the hydrophobic interaction has the important status.

    Solar-like oscillations detected in both components of the binary system alpha Centauri provide strong constraints on the fundamental parameters of the stellar system. We model alpha Centauri by means of a Levenberg-Marquardt minimization algorithm including seismic and classical constraints. Computations, that were perfomed decreasing significanly the weight of alpha Cen B seismic data in the calibration procedure, predict small separations in good agreement with new observations of solar-like oscillations in alpha Cen B by Bedding (these proceedings).

  14. Tetrameric structure of centromeric nucleosomes in interphase Drosophila cells.

    Directory of Open Access Journals (Sweden)

    Yamini Dalal

    2007-08-01

    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.

    Detection of quiescent X-ray emission from the stellar components of the Alpha Cen system: Alpha Cen A (G2 V) and Alpha Cen B (K1 V) is reported. Contrary to previous theoretical expectations, both stars are found to be X-ray emitters and at about the same level: L sub x = 1.2 x 10 to the 27th and 2.8 x 10 to the 27th ergs/s for A and B, respectively; the sum of these values is in agreement with the emission level previously reported for Alpha Cen by Nugent and Garmire (1978). Comparison with previous chromospheric and transition region measurements suggests that Alpha Cen A and B may have changed in relative strength in recent years. The coronal temperature of the combined Cen AB source, which is dominated (approximately 2/3 of the total) by the K star is (2.1 + or - 0.4) x 10 to the 6th K, similar to that of the average solar corona; it is noted that this value is not consistent with the estimate of 5 x 10 to the 5th K quoted by Nugent and Garmire.

    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.

  17. 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.

  18. Single-epitope recognition imaging of native chromatin

    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.

    Context. The existence of satellite galaxy planes poses a major challenge for the standard picture of structure formation with non-baryonic dark matter. Recently Tully et al. (2015, ApJ, 802, L25) reported the discovery of two almost parallel planes in the nearby Cen A group using mostly high-mass galaxies (MBteam detected a large number of new group member candidates in the Cen A group. This dwarf galaxy sample, combined with other recent results from the literature, enables us to test the galaxy distribution in the direction of the Cen A group and to determine the statistical significance of the geometric alignment. Methods: Taking advantage of the fact that the two galaxy planes lie almost edge-on along the line of sight, the newly found group members can be assigned relative to the two planes. We used various statistical methods to test whether the distribution of galaxies follows a single normal distribution or shows evidence of bimodality as has been reported earlier. Results: We confirm that the data used for the Tully et al. study support the picture of a bimodal structure. When the new galaxy samples are included, however, the gap between the two galaxy planes is closing and the significance level of the bimodality is reduced. Instead, the plane that contains Cen A becomes more prominent. Conclusions: We found evidence that the galaxy system around Cen A is made up of only one plane of satellites. This plane is almost orthogonal to the dust plane of Cen A. Accurate distances to the new dwarf galaxies will be required to measure the precise 3D distribution of the galaxies around Cen A.

  20. The Dynamo Clinical Trial

    Ayres, Thomas R.

    2016-04-01

    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.)

    [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 ...

    2004-08-15

    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.

  3. Intrinsic brain network abnormalities in migraines without aura revealed in resting-state fMRI.

    Directory of Open Access Journals (Sweden)

    Ting Xue

    Full Text Available BACKGROUND: Previous studies have defined low-frequency, spatially consistent intrinsic connectivity networks (ICN in resting functional magnetic resonance imaging (fMRI data which reflect functional interactions among distinct brain areas. We sought to explore whether and how repeated migraine attacks influence intrinsic brain connectivity, as well as how activity in these networks correlates with clinical indicators of migraine. METHODS/PRINCIPAL FINDINGS: Resting-state fMRI data in twenty-three patients with migraines without aura (MwoA and 23 age- and gender-matched healthy controls (HC were analyzed using independent component analysis (ICA, in combination with a "dual-regression" technique to identify the group differences of three important pain-related networks [default mode network (DMN, bilateral central executive network (CEN, salience network (SN] between the MwoA patients and HC. Compared with the HC, MwoA patients showed aberrant intrinsic connectivity within the bilateral CEN and SN, and greater connectivity between both the DMN and right CEN (rCEN and the insula cortex - a critical region involving in pain processing. Furthermore, greater connectivity between both the DMN and rCEN and the insula correlated with duration of migraine. CONCLUSIONS: Our findings may provide new insights into the characterization of migraine as a condition affecting brain activity in intrinsic connectivity networks. Moreover, the abnormalities may be the consequence of a persistent central neural system dysfunction, reflecting cumulative brain insults due to frequent ongoing migraine attacks.

    Full Text Available This study investigated the potential of Casuarina equisetifolia needle (CEN on the removal of two important dyes, methylene blue (MB and malachite green (MG, by batch adsorption experiments. Characterisation of CEN’s functional groups was done using Fourier Transform infrared spectroscopy while elemental analysis was carried out using CHNS analysis and X-ray fluorescence. The experiments were carried out by varying the adsorbent dosage, pH, ionic strength, contact time and initial dye concentration. The pseudo-second-order kinetics model best represented the experimental data for both CEN-MB and CEN-MG systems. The Weber–Morris intraparticle diffusion model showed that intraparticle diffusion is not the rate-limited step for both adsorbates, while the Boyd model suggested both systems could be controlled by film diffusion. The Langmuir, Freundlich and Dubinin–Radushkevich isotherm models were used for describing the adsorption process. Of these, the Langmuir model best represented both adsorbents systems (CEN-MB and CEN-MG giving maximum adsorption capacity (qm of 110.8 and 77.6 mg g−1, respectively, at 25 °C. Thermodynamics studies showed that both adsorption systems are spontaneous and endothermic.

    In 1998, SCK-CEN took the initiative to include social sciences and humanities into its research programme. Within this context, four projects were defined, respectively on sustainability and nuclear development; transgenerational ethics related to the disposal of long-lived radioactive waste; legal aspects and liability; emergency communication and risk perception. Two reflection groups were established, on expert culture and ethical choices respectively, in order to deepen insight while creating exchange of disciplinary approaches of the committed SCK-CEN researchers and social scientists. Within the context of SCK-CEN's social sciences and humanities programme, collaborations with various universities were initiated, teams consisting of young doctorate and post-doctorate researchers and university promotors with experience in interaction processes of technology with society were established and steering committees with actors and external experts were set up for each project. The objectives and main achievements in the four projects are summarised.

    Collaboration between Belgian experts and Argentina on the commissioning of Argentine reactors helped overcome problems caused by delays with construction. Marc Scibetta, deputy manager for nuclear materials science, from the Belgian Nuclear Research Centre (SCK CEN) gave an interview in which he told some facts to Lubomir Mitev of NucNet. The cooperation between SCK CEN an Argentina's Comision Nacional de Energia Atomica (CNEA) started in 2002. The first project was a support for the safety evaluation of the Atucha-1 reactor pressure vessel. When Argentina resumed the construction of Atucha-2 in 2006 - originally, construction started in 1981 but was suspended in 1985 due to financial reasons -, SCK CEN was asked to develop and implement a surveillance programme for the unit.

    Infrared Space Observatory 3 - 25 $\\mu$m spectra of the R Coronae Borealis stars V854 Cen, R CrB, and RY Sgr are presented and discussed. Sharp emission features coincident in wavelengths with the well known Unidentified Emission Features are present in the spectrum of V854 Cen but not of R CrB or RY Sgr. Since V854 Cen is not particularly H-poor and has a 1000 times more H than the other stars, the emission features are probably from a carrier containing hydrogen. There is a correspondence between the features and emission from laboratory samples of hydrogenated amorphous carbon. A search for C$_{60}$ in emission or absorption proved negative. Amorphous carbon particles account for the broad emission features seen between 6 - 14 $\\mu$m in the spectrum of each star.

    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...

  12. 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 $E_{cen}$.

    We present the widest-field resolved stellar map to date of the closest (D˜ 3.8 Mpc) massive elliptical galaxy NGC 5128 (Centaurus A; Cen A), extending out to a projected galactocentric radius of ˜150 kpc. The data set is part of our ongoing Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) utilizing the Magellan/Megacam imager. We resolve a population of old red giant branch (RGB) stars down to ˜1.5 mag below the tip of the RGB, reaching surface brightness limits as low as {μ }V,0˜ 32 mag arcsec-2. The resulting spatial stellar density map highlights a plethora of previously unknown streams, shells, and satellites, including the first tidally disrupting dwarf around Cen A (CenA-MM-Dw3), which underline its active accretion history. We report 13 previously unknown dwarf satellite candidates, of which 9 are confirmed to be at the distance of Cen A (the remaining 4 are not resolved into stars), with magnitudes in the range {M}V=-7.2 to -13.0, central surface brightness values of {μ }V,0=25.4{--}26.9 mag arcsec-2, and half-light radii of {r}h=0.22{--}2.92 {{kpc}}. These values are in line with Local Group dwarfs but also lie at the faint/diffuse end of their distribution; interestingly, CenA-MM-Dw3 has similar properties to the recently discovered ultradiffuse galaxies in Virgo and Coma. Most of the new dwarfs are fainter than the previously known Cen A satellites. The newly discovered dwarfs and halo substructures are discussed in light of their stellar populations, and they are compared to those discovered by the PAndAS survey of M31. This paper includes data gathered with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile.

    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.

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

    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

    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.

    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

  13. Social Sciences in Nuclear Research

    Energy Technology Data Exchange (ETDEWEB)

    Eggermont, G

    2001-04-01

    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.

    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...

  5. 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.

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

    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.

  8. Lanthanides and other spectral oddities in a Centauri

    CERN Document Server

    Cowley, C R; Gonzalez, J F

    2010-01-01

    Context: There is considerable interest in the helium variable a Cen as a bridge between helium-weak and helium-strong CP stars. Aims: We investigate Ce III and other possible lanthanides in the spectrum the of hottest chemically peculiar (CP) star in which these elements have been found. A {Kr II line appears within a broad absorption which we suggest may be due to a high-level transition in C II. Methods: Wavelengths and equivalent widths are measured on high-resolution UVES spectra, analyzed, and their phase-variations investigated. Results: New, robust identifications of Ce III and Kr II are demonstrated. Nd III is likely present. A broad absorption near 4619[A] is present at all phases of a Cen, and in some other early B stars. Conclusions: The presence of lanthanides in a Cen strengthens the view that this star is a significant link between the cooler CP stars and the hotter helium-peculiar stars. Broad absorptions in a Cen are not well explained.

  12. Deriving stellar inclination of slow rotators using stellar activity

    Energy Technology Data Exchange (ETDEWEB)

    Dumusque, X., E-mail: xdumusque@cfa.harvard.edu [Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138 (United States)

    Stellar inclination is an important parameter for many astrophysical studies. Although different techniques allow us to estimate stellar inclination for fast rotators, it becomes much more difficult when stars are rotating slower than ∼2-2.5 km s{sup –1}. By using the new activity simulation SOAP 2.0 which 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 HD 189733, we estimate the stellar inclination to be i=84{sub −20}{sup +6} deg, which implies a star-planet obliquity of ψ=4{sub −4}{sup +18} considering previous measurements of the spin-orbit angle. For α Cen B, we derive an inclination of i=45{sub −19}{sup +9}, which implies that the rotational spin of the star is not aligned with the orbital spin of the α Cen binary system. In addition, assuming that α Cen Bb is aligned with its host star, no transit would occur. The inclination of α Cen B can be measured using 40 radial-velocity measurements, which is remarkable given that the projected rotational velocity of the star is smaller than 1.15 km s{sup –1}.

    The study was performed to investigate the effects of using cow effluent for the cultivation of Spirulina platensis on its biomass production and cell physiology. S. platensis was cultivated in three different cow effluents (CE) used as cultivation medium during 15 days. CE was prepared using dry cow manures, and it was further modified with supplement of NaNO3 (CEN) and NaNO3 + NaCl (CENS). High nitrate value stimulated chlorophyll-a and total protein content of the cyanobacterium and also biomass production in standards medium (SM) and CEN media. Total carbohydrate content of S. platensis grown in CE media was found to be higher (p biomass and biochemical compounds by the cyanobacterium grown on the CE and SM media were evaluated by using multivariate approach. Conductivity, oxidation reduction potential (ORP), salinity, pH, and TDS played important role (p biomass production, filament length, and proline. Canonical correspondence analysis proposed that biochemical compounds of S. platensis were not only affected by salinity and nutrition of media but also by pH and ORP. The present study indicated that CEN as a low cost model medium had high potential for the production of biomass by S. platensis with high protein content.

    The authors described the general principles governing the design of a laboratory for experimenting and handling radioactive substances. The difficulties encountered are of two types: 1) those due to the dangers of external irradiation; 2) those due to the dangers of internal contamination. As an example, the authors describe the French achievements in this field and in particular: - the high-activity laboratories at Saclay; - the laboratory for the examination of irradiated fuels at Saclay; - the 'hot' laboratory of the CEN-Grenoble; - the alpha, beta and gamma laboratories of the CEN-Fontenay-aux-Roses. Finally, the report describes the protective materials used for these installations.

    The effectiveness of enteral and parenteral feeding in supporting a satisfactory nutrition status and/or reversing protein-energy malnutrition was evaluated in nine children, ages 1 to 7 years (eight female), with Wilms' tumors. At the onset of treatment, eight patients received comprehensive enteral nutrition (CEN) which included intense nutritional counseling and oral supplements while one received total parenteral nutrition (TPN). Despite CEN, the initial, intense treatment period was associated with a decreased energy intake (64 +/- 27% Recommended Dietary Allowances), dramatic weight loss (22 +/- 7% by 26 +/- 17 days from the beginning of treatment), decreased skinfold thickness (total lymphocyte count were 3.02 +/- 0.45 g/dl, 155 +/- 40 mg/dl, and, 655 +/- 437/mm3, respectively; all children had abnormal anthropometric measurements and anergy to recall skin test antigens. TPN for 28 or more days supported weight gain (+ 2.44 kg), increased serum albumin (+ 0.58 +/- 0.47 g/dl) and transferrin (+ 76 +/- 34 mg/dl), and reversed anergy despite low total lymphocyte counts. During maintenance treatment, nutritional status was maintained or restored with CEN in the group who responded. These preliminary data document the severity of protein-energy malnutrition which accompanies initial, intense treatment of children with Wilms' tumors, the nutritional and immunological benefits of TPN during continuing intense treatment and the effectiveness of CEN in maintaining a satisfactory nutritional status during maintenance treatment.

  3. Proxima's orbit around Alpha Centauri

    CERN Document Server

    2016-01-01

    Proxima and Alpha Centauri AB have almost identical distances and proper motions with respect to the Sun. Although the probability of such similar parameters is in principle very low, the question whether they actually form a single gravitationally bound triple system has been open since the discovery of Proxima one century ago. Owing to recent high precision radial velocity measurements and the revision of the parameters of the Alpha Cen pair, we show that Proxima and Alpha Cen are gravitationally bound with a high degree of confidence. The orbital period of Proxima is approximately 600 000 years, with a moderate excentricity of 0.42 +0.07 -0.08. Proxima comes within 5.3 -0.9 +1.2 kAU of Alpha Cen at periastron, and the apastron occurs at 12.9 +0.3 -0.1 kAU. This orbital motion may have influenced the formation or evolution of the recently discovered planet orbiting Proxima as well as circumbinary planet formation around Alpha Cen.

  4. 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.

    2014-10-01

    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.

    Centaurus (Cen) A represents one of the best candidates for an isolated, compact, highly polarized source that is bright at typical cosmic microwave background (CMB) experiment frequencies. We present measurements of the 4 degree by 2 degree region centered on Cen A with QUaD, a CMB polarimeter whose absolute polarization angle is known to 0.5 degrees. Simulations are performed to assess the effect of misestimation of the instrumental parameters on the final measurement, and systematic errors due to the field's background structure and temporal variability from Cen A's nuclear region are determined. The total (Q, U) of the inner lobe region is (1.00 +/- 0.07 (stat.) +/- 0.04 (sys.), -1.72 +/- 0.06 +/- 0.05) Jy at 100 GHz and (0.80 +/- 0.06 +/- 0.06, -1.40 +/- 0.07 +/- 0.08) Jy at 150 GHz, leading to polarization angles and total errors of -30.0 +/- 1.1 degrees and -29.1 +/- 1.7 degrees. These measurements will allow the use of Cen A as a polarized calibration source for future millimeter experiments.

  7. Numerical Simulation of Star Formation by the Bow Shock of the Centaurus A Jet

    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.

  8. Constraining fundamental stellar parameters using seismology. Application to Alpha Centauri AB

    CERN Document Server

    Montalban, J

    2005-01-01

    We apply the Levenberg-Marquardt minimization algorithm to seismic and classical observables of the Alpha Cen binary system in order to derive the fundamental parameters of Alpha Cen A+B and to analyze the dependence of these parameters on the chosen observables, on their uncertainty and on the physics used in stellar modelling. The seismological data are those by Bouchy & Carrier (2002) for Alpha Cen A, and those by Carrier & Bourban (2003) for Alpha Cen B. We show that while the fundamental stellar parameters do not depend on the treatment of convection adopted (Mixing Length Theory -- MLT -- or ``Full Spectrum of Turbulence'' -- FST), the age of the system depends on the inclusion of gravitational settling, and is deeply biased by the small frequency separation of component B. We try to answer the question of the universality of the mixing length parameter, and we find a statistically reliable dependence of the alpha--parameter on the HR diagram location (with a trend similar to the one predicted b...

  9. Testing the two planes of satellites in the Centaurus Group

    CERN Document Server

    Müller, Oliver; Pawlowski, Marcel S; Binggeli, Bruno

    2016-01-01

    The existence of satellite galaxy planes poses a major challenge for the standard picture of structure formation with non-baryonic dark matter. Recently Tully et al. (2015) reported the discovery of two almost parallel planes in the nearby Cen A group using mostly high-mass galaxies (M$_B$ $<$ -10 mag) in their analysis. Our team detected a large number of new group member candidates in the Cen A group (M\\"uller et al. 2016). This dwarf galaxy sample combined with other recent results from the literature enables us to test the galaxy distribution in the direction of the Cen A group and to determine the statistical significance of the geometric alignment. Taking advantage of the fact that the two galaxy planes lie almost edge-on along the line of sight, the newly found 13 group members by Crnojevic et al. (2014, 2016) and our 16 new Cen A group candidates (M\\"uller et al. 2016) can be assigned relative to the two planes. We use various statistical methods to test whether the distribution of galaxies follows...

  2. 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...

    2016-01-01

    Empirical evidence for the involvement of nonradial pulsations (NRP's) in the mass loss from Be stars ranges from (i) a singular case (\\object{$\\mu$ Cen}) of repetitive mass ejections triggered by multi-mode beating to (ii) several photometric reports about enormous numbers of pulsation modes popping up during outbursts and on to (iii) effective single-mode pulsators. The BRITE Constellation of nanosatellites was used to obtain mmag photometry of the Be stars $\\eta$ and \\object{$\\mu$ Cen}. In the low-inclination star \\object{$\\mu$ Cen}, light pollution by variable amounts of near-stellar matter prevented any new insights into the variability and other properties of the central star. In the equator-on star \\object{$\\eta$ Cen}, BRITE photometry and {\\sc Heros} echelle spectroscopy from the 1990s reveal an intricate clockwork of star-disk interactions. The mass transfer is modulated with the frequency difference of two NRP modes and an amplitude three times as large as the amplitude sum of the two NRP modes. Thi...

  12. Haunted by ghosts: prevalence, predictors and outcomes of spirit possession experiences among former child soldiers and war-affected civilians in Northern Uganda.

    Phenomena of spirit possession have been documented in many cultures. Some authors have argued that spirit possession is a type of psychopathology, and should be included as a category in diagnostic manuals of mental disorders. However, there are hardly any quantitative studies that report the prevalence of spirit possession on a population level and that provide evidence for its validity as a psychopathological entity. In an epidemiological study that was carried out in 2007 and 2008 with N = 1113 youths and young adults aged between 12 and 25 years in war-affected regions of Northern Uganda we examined the prevalence, predictors and outcomes of cen, a local variant of spirit possession. Randomly selected participants were interviewed using a scale of cen, measures of psychopathology (PTSD and depression) as well as indicators of functional outcome on different levels, including suicide risk, daily activities, perceived discrimination, physical complaints and aggression. We found that cen was more common among former child soldiers then among subjects without a history of abduction. Cen was related to extreme levels of traumatic events and uniquely predicted functional outcome even when the effects of PTSD and depression were controlled for. Our findings show that a long-lasting war that is accompanied by the proliferation of spiritual and magical beliefs and propaganda can lead to high levels of harmful spirit possession. In addition, we provide evidence for the incremental validity of spirit possession as a trauma-related psychological disorder in this context.
