Educação escolar, tradição e oralidade Negro-Brasileira
The present text was elaborated from a case study on black-Brazilian education and orality, and consists of an academic-reflective approach on some aspects of black school education; of African traditions and cultures; and of the black-Brazilian orality. This approach is based, in particular, on the following works, with their respective authors: Traditional Culture Banto, by Raul Ruiz de Asúa Altuna; The Place of Culture, by Homi Kuane Bhabha; Living Tradition, by Hampâté Bâ; and, Public Policies of Affirmative Actions: Education and Abá (thought) Black-Brazilian Diásporico, by Jorge Manoel Adão. At the same time we find that oral tradition is a constituent part of the formative matrix of Brazilian culture, in its artistic, festive, religious and popular expressions; we realize that, from the indicators, we have an educational system still not attractive to pardos and blacks for not aggregating their cultural identity and for not recognizing the singularities of this specific group. Singularities such as: early entry into the labor market; the lack of a social quality in public education, in which most of them have access; and to a programmatic content that does not recognize the cultural universe, from its roots, of the blacks and that does not encourage the construction of an identity knowledge. As well as racism and prejudice in the school environment and in the classroom, which consequently translates into avoidance and discontinuity of studies and lack of references, perspectives for the achievement of a trajectory of personal, academic and professional success.O presente texto foi elaborado a partir de um estudo de caso sobre educação e oralidade negro-brasileira e consiste em uma abordagem acadêmico-reflexiva sobre alguns aspectos da educação escolar de negros; da tradição e culturas africanas; e, da oralidade negro-brasileira. Esta abordagem se embasa teoricamente, em especial, nas seguintes obras, com seus respectivos autores: Cultura Tradicional Banto, de Raul Ruiz de Asúa Altuna; O Local da Cultura, de Homi Kuane Bhabha; Tradição Viva, de Hampâté Bâ; e, Políticas Públicas de Ações Afirmativas: Educação e Abá (pensamento) Negro-Brasileiro Diásporico, de Jorge Manoel Adão. Ao mesmo tempo em que constatamos que a tradição oral é parte constituinte da matriz formadora da cultura brasileira, em suas expressões artísticas, festivas, religiosas e populares; percebemos que, desde os indicadores, temos um sistema educacional ainda pouco atraente aos pardos e pretos por não agregar a sua identidade cultural e por não reconhecer às singularidades deste grupo específico. Singularidades como: a entrada precoce no mercado de trabalho; a falta de uma qualidade social no ensino público, em que majoritariamente estes têm acesso; e, a um conteúdo programático que não reconhece o universo cultural, a partir de suas raízes, dos negros e que não incentiva a construção de um saber identitário. Assim como o racismo e o preconceito no ambiente escolar e em sala de aula que, consequentemente, se traduz em evasão e descontinuidade dos estudos e falta de referenciais, de perspectivas para a realização de uma trajetória de sucesso pessoal, acadêmico e profissional
Supplementary taxonomic description of Demidospermus pinirampi (Monogenoidea, Dactylogyridae), with a new host record and an expansion of its distribution range
During a survey conducted in the Lajeado Reservoir of the Tocantins River, in the state of Tocantins, Brazil, dactylogyrids were recovered from the gills of Pimelodina flavipinnis. Initial morphological analysis showed these dactylogyrids shared aspects of character with species of Demidospermus, with affinity to Demidospermus pinirampi, despite exhibiting differences with the original description by Kritsky et al. (1987) regarding the vagina, the base of the male copulatory organ and the shape and length of the bars. The analysis of the holotypes of D. pinirampi and its most morphologically close species, Demidospermus luckyi, revealed that these dactylogyrids were indeed D. pinirampi. This study therefore reports a new host and locality of occurrence, and reviews some measurements of the original description, supplementing and enhancing the morphological diagnosis of D. pinirampi.Fundacao de Amparo a Pesquisa do Estado de Sao Paulo - FAPESPFAPESPCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior - CAPESConselho Nacional de Desenvolvimento Cientifico e Tecnologico - CNPqUniv Estadual Campinas, Programa Posgrad Biol Anim, Predio PG IB, Bloco O,CP 6109,Ave Bertrand Russel S-N, BR-13083865 Campinas, SP, BrazilUniv Fed Tocantins, Programa Posgrad Ecol Ecotonos, Rua 03,Quadra 17,Lote 11 S-N, BR-77500000 Porto Nacl, Tocantins, BrazilUniv Taubate, Dept Biol, Av Tiradentes 500, BR-12030180 Taubate, SP, BrazilUniv Fed Sao Paulo, Dept Ecol & Biol Evolut, Rua Prof Artur Riedel 275, BR-09972270 Diadema, SP, BrazilUniv Fed Sao Paulo, Dept Ecol & Biol Evolut, Rua Prof Artur Riedel 275, BR-09972270 Diadema, SP, BrazilFAPESP: 2013/21374-6FAPESP: 2013/20770-5CNPq: 305630/2013-0Web of Scienc
PREVISÃO HIDROLÓGICA DE CHEIA SAZONAL DO RIO XINGU,ALTAMIRA-PA
No presente trabalho foram investigados os aspectos climatológicos do regime hidrológico do rio Xingu, incluindo a elaboração de um modelo estatístico de previsão das cheias sazonais no município de Altamira-PA. Os resultados mostraram que o pico das cheias ocorre entre os meses de março a maio (MAM) e a variabilidade fluviométrica é dependente da ocorrência de precipitação do rio Xingu (entre os estados do Pará e Mato Grosso), bem como dos padrões de temperatura da superfície do mar no Pacífico e Atlântico que influenciam nas bandas de nuvens convectivas da Zona de Convergência do Atlântico Sul e Zona de Convergência Intertropical. O modelo estatístico de previsão hidrológica do rio Xingu (Altamira-PA), desenvolvido através da regressão linear múltipla para prever a cota da cheia sazonal (MAM) levando em consideração as variáveis preditoras (explicativas) temperatura da superfície do mar e a precipitação, obteve resultado satisfatório, pois acompanhou bem a cota observada e, além disso, apresentou correlação significativa entre as varáveis e valor considerado adequado e bom para o coeficiente de Nash Sutcliffe, além de baixo erro

Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

The production of tt‾ , W+bb‾ and W+cc‾ is studied in the forward region of proton–proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of 1.98±0.02 fb−1 . The W bosons are reconstructed in the decays W→ℓν , where ℓ denotes muon or electron, while the b and c quarks are reconstructed as jets. All measured cross-sections are in agreement with next-to-leading-order Standard Model predictions.The production of , and is studied in the forward region of proton-proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of 1.98 0.02 \mbox{fb}^{-1}.

Multidifferential study of identified charged hadron distributions in -tagged jets in proton-proton collisions at 13 TeV
Jet fragmentation functions are measured for the first time in proton-proton
collisions for charged pions, kaons, and protons within jets recoiling against
a boson. The charged-hadron distributions are studied longitudinally and
transversely to the jet direction for jets with transverse momentum 20 GeV and in the pseudorapidity range . The
data sample was collected with the LHCb experiment at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 1.64 fb. Triple
differential distributions as a function of the hadron longitudinal momentum
fraction, hadron transverse momentum, and jet transverse momentum are also
measured for the first time. This helps constrain transverse-momentum-dependent
fragmentation functions. Differences in the shapes and magnitudes of the
measured distributions for the different hadron species provide insights into
the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any
