Petrographic characterization of Archaean impact spherule layers from Fairview Gold Mine, northern Barberton Greenstone Belt, South Africa
No full textThe oldest known evidence of large impacts in Early Earth history are Archaean to Palaeoproterozoic impact spherule layers of the Barberton Greenstone Belt in South Africa and the Pilbara craton in Western Australia. Four drill core sections (BH5901, BH5907, BH5911 and BH5949) containing spherule layers were intersected in exploration drilling at Fairview Gold Mine in the northern Barberton Greenstone Belt. Here, we provide a first detailed mineralogical study of these new spherule layer intersections. The spherule layers are densely packed with sand-sized, spherical to ovoid, i.e., in part strongly deformed, “beads”. They generally have morphological and textural features similar to other 3.4–3.2 Ga old spherule layers of the Barberton Greenstone Belt. The Fairview spherule layers are stratigraphically positioned at the contact between the silicified volcanic tuff of the uppermost unit of the Onverwacht Group and the lowermost siliciclastic rocks of the Fig Tree Group, like the S2 and S4 layers in the southern, and S3 layer in the northern, domain of the greenstone belt. Micro-XRF scanning allowed (i) to distinguish spherule layers from their host rocks by their major element distribution, and (ii) to characterize secondary alteration and micro-deformation features in the SL and host rocks. Ni–Cr spinel, the only primary mineral in evidence in these sections, is not distributed uniformly along a spherule layer intersection, and occurrences can not be stratigraphically correlated between the four layer intersections either. Spinel crystals vary with respect to Ni, Cr, Fe and Zn contents and respective zonation patterns for these elements. Zinc abundances are likely related to post-depositional hydrothermal overprint. The results of this investigation comprising geological, petrographic, semiquantitative micro-X-ray fluorescence spectrometry, and quantitative electron microprobe analysis on spinel support a complex and heterogeneous genetic process that must have taken place during spherule formation in an impact vapor plume and in post-depositional times. The Fairview spherule layers are thought to possibly represent the product of a single impact event. They represent fallout into deep-water conditions, as they lack evidence for reworking or sorting by current or wave action. The heterogeneous Ni–Cr spinel concentrations are similar to what has been reported for spinel occurrences in the S3 layer, but considering the complex tectonic overprint on this lithostratigraphic sequence at the changeover from the Onverwacht to the Fig Tree Group it is not possible to conclude whether or not these spherule layers represent the same impact event162CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQGD-142442/2015-1SWE 290132/2017-
Drought in the semiarido baiano and the hydrometeor (rainfall) in the context of published media in the Bahia state
No full textA mídia cada vez mais tem se encarregado de divulgar informações relacionadas aos fenômenos climáticos e meteorológicos, assim como, também, é crescente o número de pesquisas que buscam investigar a forma como os temas referentes ao clima, ao tempo e ao comportamento deles vem sendo apresentado nas diversas mídias (jornais, revistas, rádio, internet, televisão). Sendo assim, a presente pesquisa buscou analisar as notícias relacionadas ao hidrometeoro (chuva), na região do semiárido baiano, no período de 2012 a 2015, publicadas pelos jornais (Correio da Bahia e A Tarde) de grande circulação no Estado da Bahia. Observou-se que as notícias fazem apologia a expectativa da chuva, e que muitas delas colocam que o sofrimento da população está diretamente conectado ao fenômeno climático. Os adjetivos utilizados pela mídia aos eventos climáticos são pejorativos e favorecem para a construção de um significado equivocado sobre o clima da região131249255The media has been in charge of disseminating information related to climatic and meteorological phenomena, as well as increasing the number of researches investigating how the themes related to climate, weather and their behavior, have been presented by the media (newspapers, magazines, radio, internet, television). Therefore, this research aimed to analyze the news related to the hydrometeor (rainfall), in the region of Bahia’s semiarido, from 2012 to 2015 period, published by two newspapers with a great circulation in the State of Bahia (Correio da Bahia and A Tarde). We observed
that most of the news reported the expectation of rain and, generally, they highlight that the population misery is directly connected to the climatic phenomenon. The adjectives used by the media to the climatic events are depreciatory and negative promoting a wrong concept about the region’s climat
Water Resource Management in Brazil and Colombia, a Comparison of its instruments
No full textBrasil y Colombia son considerados países con una alta disponibilidad hídrica, actualmente presentan grandes avances en la implementación de una Gestión Integrada del Recurso Hídrico, sim embargo, exhiben problemáticas comunes en relación con los diversos usuarios y los múltiples usos del recurso dentro de sus territorios. Este trabajo analiza comparativamente cinco instrumentos de gestión (planeación, clasificación de los cuerpos de agua, concesiones y cobro por uso del agua y finalmente el uso de los sistemas de información sobre recursos hídricos), renovando la discusión acerca de los modelos establecidos, donde se denotan deficiencias de aplicación normativa para ambos países. Se encontró un sistema más maduro en su proceso de instalación y con mayores garantías de participación ciudadana en Brasil, en cuanto que el sistema colombiano se encuentra en una etapa más temprana de desarrollo, existiendo una fuerte conexión con la gestión ambiental. La adopción de la cuenca hidrográfica como unidad de gestión es un punto conflictuante por no coincidir con los límites político-administrativos tradicionales. Se toma a la cuenca del río Alto Lebrija en Colombia y las cuencas de los ríos Piracicaba, Capivari y Jundiaí, en Brasil, como ejemplos locales para un mejor entendimiento de la comparación propuesta22217319
Of actors, functions, and fuels: Exploring a second generation ethanol transition from a technological innovation systems perspective in Brazil
No full textThis article analyzes the transition towards second-generation (2G) biofuels during the 2005–2018 period in Brazil, which is a world leader of first-generation (1G) biofuels. In the case of Brazil 2G technologies are associated with sugarcane and the technologies of this transition considered in this article are enzymatic hydrolysis and energy cane. The analytical background used is the technological innovation systems (TIS) framework. The functioning of the innovation system is studied using scientific papers, patents, reports, newspaper information, and other data from Brazilian funding agencies. The paper examines how the functions of the Brazilian bioethanol TIS related to 2G biofuels operated and were interconnected in this period. We found that the knowledge development and resource mobilization functions operated positively but others did not, especially guidance of the search, market formation and creation of legitimacy, revealing an unbalanced system transformation. During this period there were two important phases, one dominated by academic actors and the other by the federal development bank. However, we found that the functions were not enough to explain the TIS evolution, and that the external context of the global TIS and the Brazilian macroeconomic dynamic were also very important to explain this evolution. We conclude that the transition was not completed and that in the future policies should consider system dynamics and context evolution70FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP2017/03407-
Student enrolment in geology from a systemic earth science education perspective: an italian case study
No full textThe knowledge of our planet should represent a common background for active and responsible citizenship and should be provided by the school. Although earth science is present in all Italian school curricula, most teachers do not have a strong geological background and that affects earth science education. On the other hand, the number of students that enrol in geology as an academic major has significantly decreased in the last 20 years. In this paper we suggest that the teaching should be suggested to geology students as a career possibility, so to improve the quality of the geological education in school and also on the enrolment in geology courses503438La connaissance de notre planète doit représenter un fond commun pour une citoyenneté active et responsable et doit être apportée par l'école. Bien que les sciences de la terre soient présentes dans tous les programmes scolaires italiens, la plupart des enseignants n'ont pas une solide formation
géologique et cela affecte l'enseignement des sciences de la terre. D'autre part, le nombre d'étudiants qui s'inscrivent en géologie en tant que discipline académique a considérablement diminué au cours
des 20 dernières années. Dans cet article, nous suggérons que l'enseignement soit proposé aux étudiants en géologie comme une possibilité de carrière, afin d'augmenter la qualité de l'enseignement géologique à l'école ainsi que l'inscription aux cours de géologi

The ratios of the inclusive cross sections as functions of transverse momentum p(T) and rapidity y, for R in the range 0.1 to 1.2 to those using R = 0.4 are presented in the region 84 < p(T)< 1588 GeV and y < 2.0. The results are compared to calculations at leading and next-to-leading order in the strong coupling constant using different parton shower models. The variation of the ratio of cross sections with R is well described by calculations including a parton shower model, but not by a leading-order quantum chromodynamics calculation including nonperturbative effects. The agreement between the data and the theoretical predictions for the ratios of cross sections is significantly improved when next-to-leading order calculations with nonperturbative effects are used.12143CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçãoSem informaçãoSem informaçãoSem informaçãoWe congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort.

Observation of electroweak production of W gamma with two jets in proton-proton collisions at root s=13 TeV
No full textCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPA first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalance in transverse momentum. The two jets are required to have a high dijet mass and a large separation in pseudorapidity. The measurement is based on data collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1). The observed (expected) significance for this process is 4.9 (4.6) standard deviations. After combining with previously reported CMS results at 8 TeV, the observed (expected) significance is 5.3 (4.8) standard deviations. The cross section for the electroweak W gamma jj production in a restricted fiducial region is measured as 20.4 +/- 4.5 fb and the total cross section for W gamma production in association with 2 jets in the same fiducial region is 108 +/- 16 fb. All results are in good agreement with recent theoretical predictions. Constraints are placed on anomalous quartic gauge couplings in terms of dimension-8 effective field theory operators.811127CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçãoSem informaçãoSem informaçãoSem informaçãoWe congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort.

Studies of charm quark diffusion inside jets using Pb-Pb and pp collisions at root s(NN)=5.02 TeV

The measurement is performed using jets with p(T)(jet) gt; 60 GeV/c and D-0 mesons with p(T)(D) gt; 4 GeV/c in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of root s(NN) = 5.02 TeV, recorded by the CMS detector at the LHC. The radial distribution of D-0 mesons with respect to the jet axis is sensitive to the production mechanisms of the meson, as well as to the energy loss and diffusion processes undergone by its parent parton inside the strongly interacting medium produced in Pb-Pb collisions. When compared to Monte Carlo event generators, the radial distribution in pp collisions is found to be well described by PYTHIA, while the slope of the distribution predicted by SHERPA is steeper than that of the data. In Pb-Pb collisions, compared to the pp results, the D-0 meson distribution for 4 < p(T)(D) < 20 GeV/c hints at a larger distance on average with respect to the jet axis, reflecting a diffusion of charm quarks in the medium created in heavy ion collisions. At higher p(T)(D), the Pb-Pb and pp radial distributions are found to be similar.12510118CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçãoSem informaçãoSem informaçãoSem informaçãoWe congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort.

Deep Underground Neutrino Experiment (DUNE): far detector technical design report: Volume III. DUNE far detector technical coordination - Executive summary
No full textSem informaçãoThe 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. 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.1581193Sem informaçãoSem informaçãoSem informaçãoThis document was prepared by the DUNE collaboration using the resources of the Fermi National Accelerator Laboratory (Fermilab), a U.S. Department of Energy, Office of Science, HEP User Facility.

The J/psi meson yield is measured at midrapidity (vertical bar y vertical bar < 0.9) in the dielectron channel, for events selected based on the charged-particle multiplicity at midrapidity (vertical bar eta vertical bar < 1) and at forward rapidity (-3.7 < eta < -1.7 and 2.8 < eta < 5.1); both observables are normalized to their corresponding averages in minimum bias events. The increase of the normalized J/psi yield with normalized dN(ch)/d eta is significantly stronger than linear and dependent on the transverse momentum. The data are compared to theoretical predictions, which describe the observed trends well, albeit not always quantitatively.810114CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçãoSem informaçãoThe ALICE Collaboration would like to thank all its engineers and technicians for their invaluable contributions to the construction of the experiment and the CERN accelerator teams for the outstanding performance of the LHC complex.
