Apendicite epiplóica: resolução videolaparoscópica

Appendices epiploicae can be the site of torsion and appendagitis. Diagnosis is currently being made by ultrasonography and computerized tomography. Expectant treatment is proposed based on the assumption that epiploic appendicitis is a self limited affection. A case of torsion of a sigmoid epiploic appendage is described. The condition was missed by abdominal ultrasonography. Correct diagnosis and immediate definite treatment were performed by videolaparoscopy

Corporate philanthropy and community involvement. Analysing companies from France, Germany, the Netherlands and Spain

[EN] This paper analyses the philanthropic behaviour of companies listed on four stock markets: the IBEX 35 (Spain), CAC-40 (France), DAX-30 (Germany) and AEX-25 (Netherlands). A bibliometric method was used to obtain keywords related to corporate philanthropy in literature, while a qualitative content analysis was undertaken to obtain specific philanthropy-related words from company annual reports. 19 groups of words (codes) were defined, indicating the terms used by companies to express corporate philanthropy and community involvement, the forms they use to express such involvement, and the formulas chosen to channel their aid. The word analysis also gave information about the stakeholders that companies take into account when they become involved in community issues. Different hypotheses were stated to determine whether the use of words was related to country, firm size (revenues and employees) or industry. The use of probit regression also allowed us to obtain combinations of these variables that explained the probability of using every term together but not separately. The results indicated that the variables which most affected philanthropic codes were country and revenues. Conversely, the variables which least influenced philanthropic codes were number of employees and industry.Miguel Molina, MBD.; Chirivella González, V.; García Ortega, B. (2016).

The Pierre Auger Observatory scaler mode for the study of solar activity modulation of galactic cosmic rays

Since data-taking began in January 2004, the Pierre Auger Observatory has been recording the count rates of low energy secondary cosmic ray particles for the self-calibration of the ground detectors of its surface detector array. After correcting for atmospheric effects, modulations of galactic cosmic rays due to solar activity and transient events are observed. Temporal variations related with the activity of the heliosphere can be determined with high accuracy due to the high total count rates. In this study, the available data are presented together with an analysis focused on the observation of Forbush decreases, where a strong correlation with neutron monitor data is found.Comision Nacional de Energia Atomica, ArgentinaFundacion AntorchasGobierno De La Provincia de Mendoza, Municipalidad de Malargue, ArgentinaNDM HoldingsValle Las Lenas, ArgentinaAustralian Research Council (ARC)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Financiadora de Estudos e Projetos (FINEP)Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Ministério da Ciência, Tecnologia e Inovação do Brasil (MCTI)Academy of Sciences of the Czech Republic (AVCR) [AV0Z10100502] [AV0Z10100522] [GAAV KJB300100801] [KJB100100904] [MSMT-CR LA08016] [LC527] [1M06002] [MSM0021620859]Centre National de la Recherche Scientifique (CNRS), Centre de Calcul IN2P3/CNRSConseil Regional Ile-de-France, Departement Physique Nucleaire et Corpusculaire [PNC-IN2P3/CNRS]Departement Sciences de l`Univers (SDU-INSU/CNRS), FranceBundesministerium fur Bildung und Forschung (BMBF)Deutsche Forschungsgemeinschaft (DFG)Finanzministerium Baden-WurttembergHelmholtz-Gemeinschaft Deutscher Forschungszentren (HGF)Ministerium fur Wissenschaft und Forschung, Nordrhein-Westfalen, GermanyMinisterium fur Wissenschaft, Forschung und Kunst, Baden-Wurttemberg, GermanyIstituto Nazionale di Fisica Nucleare (INFN)Istituto Nazionale di Astrofisica (INAF)Ministero dell Istruzione, dell Universita e della Ricerca (MIUR), ItalyConsejo Nacional de Ciencia y Tecnologia (CONACYT), MexicoMinisterie van Onderwijs, Cultuur en Wetenschap, Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO)Stichting voor Fundamenteel Onderzoek der Materie (FOM), NetherlandsMinistry of Science and Higher Education, Poland [1 P03 D 014 30] [N N202 207238]Fundacao para a Ciencia e a Tecnologia (FCT), PortugalMinistry for Higher Education, Science, and Technology, Slovenian Research Agency, SloveniaComunidad de Madrid, SpainConsejeria de Educacion de la Comunidad de Castilla La ManchaFondo Europeo de Desarrollo Regional (FEDER)Ministerio de Ciencia e Innovacion, Consolider-Ingenio, SpainGeneralitat ValencianaJunta de AndaluciaXunta de Galicia, SpainScience and Technology Facilities Council, United KingdomU.S. Department of Energy (DOE) [DE-AC02-07CH11359] [DE-FR02-04ER41300]National Science Foundation (NSF) [0450696]Grainger Foundation USAALFA-EC / HELENEuropean Union [MEIF-CT-2005-025057] [PIEF-GA-2008-220240]United Nations Educational, Scientific and Cultural Organization (UNESCO

Search for correlations between the arrival directions of IceCube neutrino events and ultrahigh-energy cosmic rays detected by the Pierre Auger Observatory and the Telescope Array

This paper presents the results of different searches for correlations between very high-energy neutrino candidates detected by IceCube and the highest-energy cosmic rays measured by the Pierre Auger Observatory and the Telescope Array. We first consider samples of cascade neutrino events and of high-energy neutrino-induced muon tracks, which provided evidence for a neutrino flux of astrophysical origin, and study their cross-correlation with the ultrahigh-energy cosmic ray (UHECR) samples as a function of angular separation. We also study their possible directional correlations using a likelihood method stacking the neutrino arrival directions and adopting different assumptions on the size of the UHECR magnetic deflections. Finally, we perform another likelihood analysis stacking the UHECR directions and using a sample of through-going muon tracks optimized for neutrino point-source searches with sub-degree angular resolution. No indications of correlations at discovery level are obtained for any of the searches performed. The smallest of the p-values comes from the search for correlation between UHECRs with IceCube high-energy cascades, a result that should continue to be monitored.ope

The rapid atmospheric monitoring system of the Pierre Auger Observatory

The Pierre Auger Observatory is a facility built to detect air showers produced by cosmic rays above 1017 eV. During clear nights with a low illuminated moon fraction, the UV fluorescence light produced by air showers is recorded by optical telescopes at the Observatory. To correct the observations for variations in atmospheric conditions, atmospheric monitoring is performed at regular intervals ranging from several minutes (for cloud identification) to several hours (for aerosol conditions) to several days (for vertical profiles of temperature, pressure, and humidity). In 2009, the monitoring program was upgraded to allow for additional targeted measurements of atmospheric conditions shortly after the detection of air showers of special interest, e. g., showers produced by very high-energy cosmic rays or showers with atypical longitudinal profiles. The former events are of particular importance for the determination of the energy scale of the Observatory, and the latter are characteristic of unusual air shower physics or exotic primary particle types. The purpose of targeted (or "rapid") monitoring is to improve the resolution of the atmospheric measurements for such events. In this paper, we report on the implementation of the rapid monitoring program and its current status. The rapid monitoring data have been analyzed and applied to the reconstruction of air showers of high interest, and indicate that the air fluorescence measurements affected by clouds and aerosols are effectively corrected using measurements from the regular atmospheric monitoring program. We find that the rapid monitoring program has potential for supporting dedicated physics analyses beyond the standard event reconstruction. </p
