The information included in the RPB and Revista Processos Químicos are parts of the results of the thesis: "Chemical characterization, evaluation of toxicity and molluscicidal activity two oils essenciais da folha of Lindic diode pepper, Citrus limon Linneo e Rizoma of Zingiber officinale Roscoe" (https://repositorio.ufpb.br/jspui/handle/tede/7038 ) (2011-05-11) by Romer Pessôa Fernandes, with advisors Victor Elias Mouchrek Filho and Antonio Gouveia de Souza. Editor Committee of RPB, on October 7 and 14, had meetings and conclude that the article will be retracted for duplicate publication and authorship ethical problems. All the authors were mailing on December. 9, 2019. Revista Peruana de Biologia calls for all readers do not cite this work, and apologises to the authors and to readers for the inconvenience caused.Declaración de retracción El Comité editor de la Revista Peruana de Biología (RPB) retracta el artículo: “Barros Gomes P.R., Batista Reis J., Pêssoa Fernandes R., Mouchrek Filho V.E., Gouveia de Souza A., Alves Fontenele M. and Caetano da Silva J. 2019.

First-Year Spectroscopy for the SDSS-II Supernova Survey

This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band light curves of supernovae in the redshift range z = 0.05 - 0.4, complementing existing surveys at lower and higher redshifts. Our goal is to better characterize the supernova population, with a particular focus on SNe Ia, improving their utility as cosmological distance indicators and as probes of dark energy. Our supernova spectroscopy program features rapid-response observations using telescopes of a range of apertures, and provides confirmation of the supernova and host-galaxy types as well as precise redshifts. We describe here the target identification and prioritization, data reduction, redshift measurement, and classification of 129 SNe Ia, 16 spectroscopically probable SNe Ia, 7 SNe Ib/c, and 11 SNe II from the first season. We also describe our efforts to measure and remove the substantial host galaxy contamination existing in the majority of our SN spectra.Comment: Accepted for publication in The Astronomical Journal(47pages, 9 figures
