Charged-particle nuclear modification factors in PbPb and pPb collisions at √=sNN=5.02 TeV

The spectra of charged particles produced within the pseudorapidity window |η| < 1 at √ sNN = 5.02 TeV are measured using 404 µb −1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in 2015. The spectra are presented over the transverse momentum ranges spanning 0.5 < pT < 400 GeV in pp and 0.7 < pT < 400 GeV in PbPb collisions. The corresponding nuclear modification factor, RAA, is measured in bins of collision centrality. The RAA in the 5% most central collisions shows a maximal suppression by a factor of 7–8 in the pT region of 6–9 GeV. This dip is followed by an increase, which continues up to the highest pT measured, and approaches unity in the vicinity of pT = 200 GeV. The RAA is compared to theoretical predictions and earlier experimental results at lower collision energies. The newly measured pp spectrum is combined with the pPb spectrum previously published by the CMS collaboration to construct the pPb nuclear modification factor, RpA, up to 120 GeV. For pT > 20 GeV, RpA exhibits weak momentum dependence and shows a moderate enhancement above unity

Caracterização epidemiológica, molecular e perfil de resistência aos antimicrobianos de Escherichia coli isoladas de criatórios suínos do sul do Brasil Epidemiology, molecular characterization and resistance to antimicrobials of Escherichia coli isolated from South-Brazilian pig herds

A colibacilose é a enfermidade entérica de maior impacto na suinocultura, sendo ocasionada por cepas enterotoxigênicas de Escherichia coli. Quarenta isolados clínicos de suínos com diarréia e 13 isolados ambientais foram analisados quanto ao perfil genotípico, relação genética e resistência antimicrobiana. O gene que codifica para a toxina Stb foi identificado em 50% dos isolados clínicos, seguido por Sta e Lt, com 35%. Dentre os fatores de adesinas pesquisados, a F18 foi encontrada em 27,5% das amostras. A técnica de ERIC-PCR utilizada para caracterização epidemiológica dos isolados, não demonstrou poder discriminatório esperado, e apesar de permitir a separação dos isolados em grupos, estes não evidenciaram grupos relacionados aos fatores de virulência. No teste de susceptibilidade antimicrobiana a maior resistência foi observada à tetraciclina, em 88,6%. O índice de resistência múltipla aos antimicrobianos (IRMA), variou entre 0 a 0,69.<br>Colibacillosis is an enteric disease with a major impact to the swine industry and is caused by enterotoxigenic strains of Escherichia coli. Forty clinical isolates from pigs with diarrhea and 13 environmental isolates were analysed regarding their genotypic profile, genetic relationship and antibiotic resistance. The most prevalent gene was Stb, identified in 50% of the isolates from clinical cases, and Sta and Lt were detected in 35% of them. Among the adesine factors investigated, F18 was found in 27.5% of the E. coli strains. The ERIC-PCR technique used for epidemiological characterization of the isolates did not show the expected discriminatory power. However, the test allowed separation of the isolates in groups, but did not evidence groups related to virulence factors. In the susceptibility test, the highest values for resistance were to tetracycline, in 88.6%. The index of multiple resistance to antimicrobials varied from 0 to 0.69

EMU: Evolutionary Map of the Universe

Original article can be found at: http://www.publish.csiro.au/ Copyright CSIRO PublishingEMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ~ 10 microJy/beam) radio continuum survey of the entire Southern Sky at 1.3 GHz, extending as far North as +30 degrees declination, with a resolution of 10 arcsec. EMU is expected to detect and catalogue about 70 million galaxies, including typical star-forming galaxies up to z~1, powerful starbursts to even greater redshifts, and AGNs to the edge of the visible Universe. It will undoubtedly discover new classes of object. This paper defines the science goals and parameters of the survey, and describes the development of techniques necessary to maximise the science return from EMU.Peer reviewe
