Granuloma periapical: tratamiento convencional. Reporte de un caso

Root granulomas are chronic periapical lesions, considered direct sequels of infectious processes resulting from pulp necrosis, extending into the periradicular region. The granulomas can occur due to failures in hard tissues, resulting from caries, fractures and surgical procedures. A conventional endodontic treatment was done with crown down technique in a patient of 15 years old with a diagnosis of periapical granuloma (chronic nonsuppurative apical periodontitis) and subsequent recovery from injury in tooth 36.Los Granulomas radiculares son lesiones periapicales crónicas, consideradas secuelas directas de procesos infecciosos resultantes de la necrosis pulpar, extendiéndose hacia la región perirradicular. Los granulomas se pueden presentar por fallas en los tejidos duros, resultantes de caries, fracturas y procedimientos quirúrgicos. Se realizó tratamiento de endodoncia convencional con preparación invertida a paciente de 15 años con diagnóstico de Granuloma periapical (periodontitis apical asintomática)y su posterior recuperación de la lesión de órgano dentario 36.

To the public space of quality: a look from Barranquilla

Barranquilla en la búsqueda de su Re-conceptualización como ciudad integral y en apuesta a el mejoramiento de su infraestructura urbana, ha propuesto impulsar el potencial que representan los escenarios públicos en la cotidianidad de la ciudadanía, elementos dinamizadores como los parques y plazas, son tomados como piezas fundamentales para el estudio, análisis y critica de su funcionalidad como ente estructurante del urbanismo en el presente artículo. Logrando de esta forma un comparativo entre la cantidad, calidad y eficiencia de los espacios públicos que posee la ciudad, teniendo en cuenta características de su estado, apreciación e importancia que representa para la población y el impacto de este elemento en el ámbito urbano. Obteniendo a raíz de esto, aspectos subjetivos y objetivos que permiten una valoración completa, un abordaje sistémico del concepto de espacio público. Las variantes que se encuentran al analizar el espacio público en la ciudad dependen de su ubicación o contexto, área, componentes y población o área de influencia que es beneficiada con este, esto pone en una disyuntiva de como realmente ser objetivos a la hora de comparar las muestras, en qué criterios se puede basar para lograr una concepción de un espacio público eficiente, pero que al mismo tiempo se rija por las necesidades y requerimientos de quienes lo habitan, el cual es concebido como todo aquel espacio o área exterior que es de interés público; de todos y para todos, donde puedes ser libre de hacer lo que desees pero respetando el derecho de los demás ciudadanos.Barranquilla in the search of its Re-conceptualization as integral city and in bet to the improvement of its urban infrastructure, has proposed to promote the potential that represent the public scenarios in the daily life of the citizens, dynamic elements such as parks and squares, are taken as fundamental pieces for the study, analysis and critique of its functionality as structuring entity of urbanism in this article. Achieving in this way a comparison between the quantity, quality and efficiency of the public spaces that the city possesses, taking into account characteristics of its state, appreciation and importance that it represents for the population and the impact of this element in the urban environment. Obtaining as a result of this, subjective and objective aspects that allow a complete evaluation, a systemic approach of the concept of public space. The variants found when analyzing the public space in the city depend on its location or context, area, components and population or area of influence that is benefited with it, this puts in a dilemma of how to really be objective when comparing the samples, on what criteria can be based to achieve a conception of an efficient public space, but at the same time governed by the needs and requirements of those who inhabit it, which is conceived as all that space or exterior area that is public interest; of all and for all, where you can be free to do what you want but respecting the rights of other citizens

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters

Standalone vertex finding in the ATLAS muon spectrometer

A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson

Measurement of the top quark-pair production cross section with ATLAS in pp collisions at \sqrt{s}=7\TeV

A measurement of the production cross-section for top quark pairs(\ttbar) in $pp$ collisions at \sqrt{s}=7 \TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in two different topologies: single lepton (electron $e$ or muon $\mu$) with large missing transverse energy and at least four jets, and dilepton ($ee$, $\mu\mu$ or $e\mu$) with large missing transverse energy and at least two jets. In a data sample of 2.9 pb-1, 37 candidate events are observed in the single-lepton topology and 9 events in the dilepton topology. The corresponding expected backgrounds from non-\ttbar Standard Model processes are estimated using data-driven methods and determined to be $12.2 \pm 3.9$ events and $2.5 \pm 0.6$ events, respectively. The kinematic properties of the selected events are consistent with SM \ttbar production. The inclusive top quark pair production cross-section is measured to be \sigmattbar=145 \pm 31 ^{+42}_{-27} pb where the first uncertainty is statistical and the second systematic. The measurement agrees with perturbative QCD calculations.Comment: 30 pages plus author list (50 pages total), 9 figures, 11 tables, CERN-PH number and final journal adde
