    Young and Intermediate-age Distance Indicators

    Distance measurements beyond geometrical and semi-geometrical methods, rely mainly on standard candles. As the name suggests, these objects have known luminosities by virtue of their intrinsic proprieties and play a major role in our understanding of modern cosmology. The main caveats associated with standard candles are their absolute calibration, contamination of the sample from other sources and systematic uncertainties. The absolute calibration mainly depends on their chemical composition and age. To understand the impact of these effects on the distance scale, it is essential to develop methods based on different sample of standard candles. Here we review the fundamental properties of young and intermediate-age distance indicators such as Cepheids, Mira variables and Red Clump stars and the recent developments in their application as distance indicators.Comment: Review article, 63 pages (28 figures), Accepted for publication in Space Science Reviews (Chapter 3 of a special collection resulting from the May 2016 ISSI-BJ workshop on Astronomical Distance Determination in the Space Age

    Volume I. Introduction to DUNE

    The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. This TDR is intended to justify the technical choices for the far detector that flow down from the high-level physics goals through requirements at all levels of the Project. Volume I contains an executive summary that introduces the DUNE science program, the far detector and the strategy for its modular designs, and the organization and management of the Project. The remainder of Volume I provides more detail on the science program that drives the choice of detector technologies and on the technologies themselves. It also introduces the designs for the DUNE near detector and the DUNE computing model, for which DUNE is planning design reports. Volume II of this TDR describes DUNE\u27s physics program in detail. Volume III describes the technical coordination required for the far detector design, construction, installation, and integration, and its organizational structure. Volume IV describes the single-phase far detector technology. A planned Volume V will describe the dual-phase technology

The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume III of this TDR describes how the activities required to design, construct, fabricate, install, and commission the DUNE far detector modules are organized and managed. This volume details the organizational structures that will carry out and/or oversee the planned far detector activities safely, successfully, on time, and on budget. It presents overviews of the facilities, supporting infrastructure, and detectors for context, and it outlines the project-related functions and methodologies used by the DUNE technical coordination organization, focusing on the areas of integration engineering, technical reviews, quality assurance and control, and safety oversight. Because of its more advanced stage of development, functional examples presented in this volume focus primarily on the single-phase (SP) detector module

    Teor de ácido cianídrico em variedades de mandioca cultivadas em quintais do estado de São Paulo Cyanide contents in cassava cultivars used for "in natura" consumption in the state of Sao Paulo, Brazil

    No Estado de São Paulo, além das culturas comerciais que destinam sua produção às indústrias de transformação ou aos mercados hortifrutigranjeiros, a mandioca (Manihot esculenta Crantz) é muito difundida em culturas denominadas de "fundo de quintal". Nesse caso, muitas variedades são cultivadas e utilizadas precipuamente para consumo doméstico, tendo o presente trabalho por objetivo avaliar a amplitude de variação do seu teor de ácido cianídrico (HCN). Foram analisadas raízes de 206 variedades originárias de uma coleta sistemática realizada em 126 municípios paulistas, utilizando-se o método de Liebig, com maceração por 24 horas. Os resultados mostraram que a amplitude máxima de variação do ácido cianídrico foi de 16 a 482 mg.kg-1 na polpa crua das raízes. A maioria das variedades (67,0%) apresentou até 100 mg.kg-1 de HCN, que, apesar de alto em relação aos citados na literatura, sugere que possa ser considerado o limite superior de segurança para variedades de mesa.<br>Cassava (Manihot esculenta Crantz) is widely cultivated in the State of Sao Paulo, Brazil, mostly as raw material for industrial purposes (production of cassava flour, starch, etc.). A small proportion of cassava production is destinated to "in natura" consumption, obtained essentially from backyard plantations. In this case, many varieties are used, with unknown cyanide contents, which can cause severe human intoxication. The main aim of this research was to evaluate the cyanide content range of these varieties. Roots of 206 varieties, collected at 126 sites in the State of São Paulo, Brazil, were analyzed as to their cyanide contents, using the Liebig method, with maceration for a 24-hour period. Results showed a cyanide content variation from 16 to 482 mg.kg-1 of HCN in the tuber root fresh pulps. On the other hand, most of the varieties (67%) under testing presented root cyanide contents below 100 mg.kg-1. So, this cyanide content may be considered as the uppermost level to be used with security on the selection of new genetic materials with lower HCN contents
