Hotel Boulevard Atlántico: un trabajo de cooperación cultural para su recuperación

El Patrimonio ocupa un lugar importante en el Turismo, una de sus etapas fundamentales son aquellas acciones vinculadas a cómo comunicar y difundir su importancia, sus alcances, sus connotaciones y la necesidad y el porqué de su preservación. En este sentido, el Grupo de Extensión en Gestión Cultural de la Facultad de Arquitectura, Urbanismo y Diseño de la Universidad Nacional Mar del Plata, la Dirección de Cultura del Partido de General Alvarado y el Programa de Rehabilitación de Áreas Históricas de Cochabamba de la Universidad Mayor de San Simón-Bolivia trabajaron en la investigación histórica del entorno de Mar del Sud y del Hotel Boulevard Atlántico. Asimismo, se realizó un relevamiento planimétrico y fotográfico del bien como también el análisis tipológico, estilístico y artístico. Este relevamiento permitió realizar un registro del estado actual de los componentes del hotel con la finalidad de establecer el estado de conservación y contribuir en recuperar la legitimidad del documento. A partir de este trabajo se busca potenciar la identidad local; esto nos llevó a determinar que el desarrollo económico local depende de la capacidad de integrar el aprovechamiento sostenible de los recursos naturales y paisajísticos que conforma el entorno del majestuoso Hotel, único en su estilo en la provincia de Buenos Aires

Relationship Between Land Use and Water Quality in a Subtropical River Basin

This study investigated the influence of land use on water quality parameters in the subtropical basin of Jundiaí-Mirim river. Water samples were collected to measure nutrients concentration and direct measurements by multiparameter probe were performed, as well as landscape analysis, using satellite images and visits in the sampling sites, besides analysis of population density data. Data were standardized and the correlation between the variables was measured using Spearman approach. Land use in the surrounding area of the sampling points had strong and significant correlations (p < 0.05) with some of the water quality parameters evaluated. These correlations had different causes, explained by the land use in a 50 m radius, or 500 m radius, or even beyond these environments studied. Landscape analysis has proved to be an important tool for understanding the interaction between water quality and land use.A influência do uso do solo sobre a qualidade da água foi investigada na bacia hidrográfica subtropical do rio Jundiaí-Mirim. Amostras de água foram coletadas para determinação de nutrientes e medidas diretas por meio de sonda multi-parâmetros foram realizadas, assim como a análise da paisagem, por meio de sensoriamento remoto e visitas nos locais de amostragem, além da avaliação de dados sobre da densidade populacional. Os dados foram padronizados e o grau de correlação entre as variáveis foi analisado usando a abordagem de Spearman. O uso da terra no entorno dos pontos de amostragem apresentou fortes e significativas correlações (p < 0,05) com alguns dos parâmetros da qualidade da água avaliados. Essa correlação se deu por diferentes causas, explicadas pelo uso da terra em um raio de 50 m, ou 500 m, ou mesmo além desses entornos estudados. A análise da paisagem demonstrou ser uma importante ferramenta para o entendimento da interação qualidade da água e uso da terra

Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb−1 of s√=7TeV proton-proton collisions

Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb−1 of pp collision data at s√=7TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from ≥6 to ≥9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m 0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV

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

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

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

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
