Selective extraction of heavy metals in bottom sediments from Tietê River, São Paulo

Sediment samples from Tietê river were submitted to chemical and sequential extractions of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn). It was followed a single extraction by using 0.1 mol L-1 hydrochloric acid and a sequential procedure to evaluate possible chemical associations described as exchangeable, carbonate, reducible oxides, sulfide, organic matter and residual fractions. High concentrations of heavy metals were determined at Pirapora reservoir, which is closer to the Metropolitan Area of São Paulo while for Barra Bonita reservoir, the results showed low concentrations for such elements. Acid volatile sulfides, grain size distribution and carbon contents were also determined.CNP

Family network of children with special health needs: implications for Nursing

OBJECTIVE: to describe appropriate sources and resources for caregivers of children with special health needs in the community. METHOD: A qualitative study that used the creativity and sensitivity dynamics speaking map, part of the sensitive creative method, involving 11 caregivers of children with special health needs who are assisted in a university hospital located in the South of Brazil. RESULTS: the maps graphically represented through the genogram and ecomap showed that the caregiving women consistently and regularly use the resources of the internal and external family network; they eventually and irregularly access the community social network for physical and psychological support. CONCLUSION: the reclusive nature of care for these children inside the family circle contributes to their social invisibility. Based on this new information, it is recommended that Nursing participate in the care that is focused on these children's families, with particular attention to their socio-cultural conditions

Temas de investigação em direitos humanos para o século XXI

Edição comemorativa do 10.º aniversário do Mestrado em Direitos Humanos da Universidade do Minho.Este livro é uma celebração do ensino e da investigação em direitos humanos que têm vindo a ser desenvolvidos, na Escola de Direito da Universidade do Minho, há já mais de uma década. A sua publicação num momento em que se avolumam os riscos para valores fundamentais subjacentes à proteção dos direitos humanos – como a igualdade e a não discriminação, a proibição da escravatura e de tratamentos cruéis, desumanos e degradantes, a liberdade de religião ou crença, entre muitos outros –, torna-o especialmente oportuno. Os sinais de aparente retrocesso no consenso das nossas sociedades a respeito desses valores – visíveis no triunfo político de discursos abertamente racistas, xenófobos, sexistas, etc. – recordam-nos que, também no mundo ocidental, os direitos humanos são um work in progress, não um dado adquirido. Os novos riscos para a dignidade da pessoa humana associados aos avanços tecnológicos andam de par com velhas formas de subalternização e de opressão. O campo para a reflexão crítica é muito vasto. Os temas que hoje (pre)ocupam académicos, decisores políticos e ativistas de direitos humanos são também aqueles que estruturam o plano de estudos do Mestrado em Direitos Humanos da Universidade do Minho. Todos estes temas surgem ao longo do presente livro, que reúne contributos de muitos dos membros da comunidade científica e académica que o Mestrado em Direitos Humanos mobilizou e ajudou a dinamizar ao longo da última década, entre docentes do Mestrado, colaboradores em júris de provas públicas e/ou na orientação de mestrandos, oradores convidados e estudantes. Os textos aqui reunidos refletem bem as sinergias interdisciplinares, interinstitucionais e inter-nacionais que o Mestrado em Direitos Humanos foi capaz de criar, não apenas pela variedade de campos disciplinares representados – Direito, Filosofia, Relações Internacionais, Antropologia –, mas também pela participação de autores que são docentes e/ou investigadores em diversas instituições nacionais e estrangeiras, como a Faculdade de Direito da Universidade do Porto, a Faculdade de Economia da Universidade de Coimbra, a Universidade Federal da Paraíba e a Pontifícia Universidade Católica de São Paulo.info:eu-repo/semantics/publishedVersio

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.

Measurement of the inclusive and differential Higgs boson production cross sections in the decay mode to a pair of τ Leptons in pp collisions at sqrt[s]=13 TeV

Measurements of the inclusive and differential fiducial cross sections of the Higgs boson are presented, using the τ lepton decay channel. The differential cross sections are measured as functions of the Higgs boson transverse momentum, jet multiplicity, and transverse momentum of the leading jet in the event, if any. The analysis is performed using proton-proton collision data collected with the CMS detector at the LHC at a center-of-mass energy of 13  TeV and corresponding to an integrated luminosity of 138  fb^{-1}. These are the first differential measurements of the Higgs boson cross section in the final state of two τ leptons. In final states with a large jet multiplicity or with a Lorentz-boosted Higgs boson, these measurements constitute a significant improvement over measurements performed in other final states

Search for top squarks in the four-body decay mode with single lepton final states in proton-proton collisions at s \sqrt{s} = 13 TeV

A search for the pair production of the lightest supersymmetric partner of the top quark, the top squark (t∼1), is presented. The search targets the four-body decay of the t∼1, which is preferred when the mass difference between the top squark and the lightest supersymmetric particle is smaller than the mass of the W boson. This decay mode consists of a bottom quark, two other fermions, and the lightest neutralino (χ∼01), which is assumed to be the lightest supersymmetric particle. The data correspond to an integrated luminosity of 138 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC. Events are selected using the presence of a high-momentum jet, an electron or muon with low transverse momentum, and a significant missing transverse momentum. The signal is selected based on a multivariate approach that is optimized for the difference between m(t∼1) and m(χ∼01). The contribution from leading background processes is estimated from data. No significant excess is observed above the expectation from standard model processes. The results of this search exclude top squarks at 95% confidence level for masses up to 480 and 700 GeV for m(t∼1) − m(χ∼01) = 10 and 80 GeV, respectively

Measurement of Energy Correlators inside Jets and Determination of the Strong Coupling Formula Presented

Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of $\sqrt{s}$=13 TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3 fb$^{−1}$. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom. By comparing the ratio of the measured three- and two-particle energy correlator distributions with theoretical calculations that resum collinear emissions at approximate next-to-next-to-leading-logarithmic accuracy matched to a next-to-leading-order calculation, the strong coupling is determined at the Z boson mass: α$_S$ (m$_Z$)=0.1229 $\frac{0.0040}{-0.0050}$ , the most precise α$_S$m$_Z$ value obtained using jet substructure observable
