A VSA search for the extended Sunyaev-Zel'dovich Effect in the Corona Borealis Supercluster
We present interferometric imaging at 33 GHz of the Corona Borealis
supercluster, using the extended configuration of the Very Small Array. A total
area of 24 deg^2 has been imaged, with an angular resolution of 11 arcmin and a
sensitivity of 12 mJy/beam. The aim of these observations is to search for
Sunyaev-Zel'dovich (SZ) detections from known clusters of galaxies in this
supercluster and for a possible extended SZ decrement due to diffuse warm/hot
gas in the intercluster medium. We measure negative flux values in the
positions of the ten richest clusters in the region. Collectively, this implies
a 3.0-sigma detection of the SZ effect. In the clusters A2061 and A2065 we find
decrements of approximately 2-sigma. Our main result is the detection of two
strong and resolved negative features at -70+-12 mJy/beam (-157+-27 microK) and
-103+-10 mJy/beam (-230+-23 microK), respectively, located in a region with no
known clusters, near the centre of the supercluster. We discuss their possible
origins in terms of primordial CMB anisotropies and/or SZ signals related to
either unknown clusters or to a diffuse extended warm/hot gas distribution. Our
analyses have revealed that a primordial CMB fluctuation is a plausible
explanation for the weaker feature (probability of 37.82%). For the stronger
one, neither primordial CMB (probability of 0.33%) nor SZ can account alone for
its size and total intensity. The most reasonable explanation, then, is a
combination of both primordial CMB and SZ signal. Finally, we explore what
characteristics would be required for a filamentary structure consisting of
warm/hot diffuse gas in order to produce a significant contribution to such a
spot taking into account the constraints set by X-ray data.Comment: 16 pages, 10 figures. Accepted in MNRA
New Approaches for Education and Training in Veterinary Public Health: The SAPUVET Projects
Continued contact between humans and animals, in combination with the ever-increasing movement of human and animal
populations that is one effect of globalization, contributes to the spread of diseases, often with detrimental effects on public
health. This has led professionals involved in both animal health and public health to recognize veterinary public health (VPH)
as a key area for their activities to address the human–animal interface. Veterinarians, a profession with major involvement in
this field, are in need of specific knowledge and skills to prevent and control public-health problems. As a result, VPH must be
directly integrated into veterinary educational programs. At present, only few veterinary schools have specific VPH programs;
in most institutions, VPH does not feature as a specific subject in either undergraduate or post-graduate curricula. SAPUVET
and SAPUVETNET II are network projects supported by the ALFA program of the European Union (EU). Their main objectives
are to reach a common understanding between European and Latin American universities in the definition of the areas in
which VPH is important in their respective countries, and to design a harmonized training program for veterinarians in VPH, by
making use of new technological applications and innovative teaching methodologies. The elaboration of educational
material in combination with case studies presenting real-life problems provides a basis to apply the knowledge acquired on
VPH. It is envisaged that the material and modules developed during the two projects will be integrated into the veterinary
curricula of the participating universities, as well as in other partner organizations
Experiences in Teaching Veterinary Public Health across Latin-America and Europe: the SAPUVETNET III Project
Experiences in Teaching Veterinary Public Health across Latin-America and Europe: the SAPUVETNET III Project
SAPUVETNET III (n. DCI-LA/2008/75) is the third phase of a series of projects, co-financed under the EU ALFA programme, aimed to support a VPH network constituted by Faculties of Veterinary Medicine of 12 Latin-american and 6 European countries in addition to various collaborating institutions/organizations both at national and international level (http://www.sapuvetnet.org). The project envisages the development and the implementation of a common VPH curriculum, through the use of innovative teaching methods, mainly based on problem solving approach. The authors present here some teaching material developed by the project as an example of new strategies/approach for teaching VPH: case studies, videos and self-learning programme on meat inspection/food hygiene, an Interactive Manual on VPH, as well as e-conferences on upcoming VPH issues. Project partners use a mail-list and distance learning platforms (e.g. Moodle, Colibri) to organize teaching activities. A Journal, “Una Salud/One Health/Uma Saúde”, is also published and distributed both as hard copy or .pdf through the web. Didactic tools produced by the SAPUVETNET projects have been and/or are being tested and used by the partner faculties and other teaching institutions, both for under and post-graduate courses. Teaching material by SAPUVETNET is distributed according to Creative Common criteria and policy (http://creativecommons.org/). It can be freely circulated and distributed, it can be used for distance learning and can be modified/adapted to the local context at each country/geographical area, even outside Latin-America and Europe. Teaching products produced under the SAPUVETNET projects are available at the URL http://www.sapuvetnet.org, or can be obtained from the project co-ordinator(s) and/or the contact persons at the partner Faculties/Universities.
The Authors would like to acknowledge all participants/collaborators/partners of the current and previous SAPUVETNET projects who greatly contributed –in different moments and at different levels- to the development of the teaching tools herein described
The 13th Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey Mapping Nearby Galaxies at Apache Point Observatory
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2,MaNGA, and eBOSS. In addition, eBOSS contains two major subprograms: TDSS and SPIDERS. This paper describes the first data release from SDSS-IV, Data Release 13 (DR13), which contains new data, reanalysis of existing data sets and, like all SDSS data releases, is inclusive of previously released data. DR13 makes publicly available 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA,the first data released from this survey. It includes new observations from eBOSS, completing SEQUELS. In addition to targeting galaxies and quasars, SEQUELS also targeted variability-selected objects from TDSS and X-ray selected objects from SPIDERS. DR13 includes new reductions ofthe SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification. DR13 releases new reductions of the APOGEE-1data from SDSS-III, with abundances of elements not previously included and improved stellar parameters for dwarf stars and cooler stars. For the SDSS imaging data, DR13 provides new, more robust and precise photometric calibrations. Several value-added catalogs are being released in tandem with DR13, in particular target catalogs relevant for eBOSS, TDSS, and SPIDERS, and an updated red-clump catalog for APOGEE.This paper describes the location and format of the data now publicly available, as well as providing references to the important technical papers that describe the targeting, observing, and data reduction. The SDSS website, http://www.sdss.org, provides links to the data, tutorials and examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned ~6-year operations of SDSS-IV.PostprintPeer reviewe
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Building S.C.A.D.A. Systems in Scientific Installations with Sardana and Taurus
International audienceSardana and Taurus form a python software suite for Supervision, Control and Data Acquisition (SCADA) optimized for scientific installations. Sardana and Taurus are open source and deliver a substantial reduction in both time and cost associated to the design, development and support of control and data acquisition systems. The project was initially developed at ALBA and later evolved to an international collaboration driven by a community of users and developers from ALBA, DESY, MAXIV and Solaris as well as other institutes and private companies. The advantages of Sardana for its adoption by other institutes are: free and open source code, comprehensive workflow for enhancement proposals, a powerful environment for building and executing macros, optimized access to the hardware and a generic Graphical User Interface (Taurus) that can be customized for every application. Sardana and Taurus are currently based on the Tango Control System framework but also capable to inter-operate to some extend with other control systems like EPICS. The software suite scales from small laboratories to large scientific institutions, allowing users to use only some parts or employ it as a whole
As redes da distinção: familiares da Inquisição na América Portuguesa do século XVIII The networks of distinction: inquisitorial officials in Eighteenth century Portuguese America
A familiatura tinha uma dupla função na sociedade portuguesa de Antigo Regime: além do controle social e religioso exercido por este corpo de oficiais inquisitoriais, a obtenção da carta de familiar também nobilitava os indivíduos que a obtinham. O artigo se propõe a estudar a presença dos oficiais leigos do Santo Oficio na América portuguesa setecentista. Procurou-se compreender o significado desse expressivo número de familiares distribuídos pelas diferentes regiões da colônia brasileira, procedendo a uma avaliação da dimensão dessa rede de agentes inquisitoriais, em particular no Rio Grande de São Pedro e na Colônia do Sacramento.<br>The institution of familiatura had a double role in the traditional Portuguese society: besides the social and religious control that was exercised by these inquisitional officials, the attainment of this title also ennobled the individuals that achieved it.
