Bonfá & P. Rodrigues.</p> <p> <b>Remarks.</b> The adult was described for the first time in a river from the central zone of Minas Gerais, in the Serra do Cipó (Novaes & Bispo 2014). Our specimens were also found in a river, Manhuaçú River, with similar proportions to the type-locality. The material examined here presents a considerable variation in size compared to the holotype. The male forewing length of our specimens is 7.5–8.5mm (n=4), while the holotype is 16.1mm. This variation could be due to the difference in elevation between these localities: 761 m a.s.l. in Cipó River, while 123 m a.s.l. in Manhuaçú River. Also, the color pattern varies, being dark brown in our material, and yellowish in the original description. This variation, however, could be related to the fading of the material originally described. Additionally, the shoulders of the penial armature of our material are wider compared to the illustrations provided in the original description (Novaes & Bispo 2014). This species was described based only on one specimen; therefore, it is necessary to examine more specimens from the type locality in order to obtain more information regarding the status of the individuals from this study. With this new record for the Doce River basin, this species expands its distribution to the east of Minas Gerais.</p>Published as part of <i>Castillo-Velásquez, R. M., Gonçalves, M. C., Correia, M.

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
APC/C and SCFcyclin F Constitute a Reciprocal Feedback Circuit Controlling S-Phase Entry
No full textSummaryThe anaphase promoting complex/cyclosome (APC/C) is an ubiquitin ligase and core component of the cell-cycle oscillator. During G1 phase, APC/C binds to its substrate receptor Cdh1 and APC/CCdh1 plays an important role in restricting S-phase entry and maintaining genome integrity. We describe a reciprocal feedback circuit between APC/C and a second ubiquitin ligase, the SCF (Skp1-Cul1-F box). We show that cyclin F, a cell-cycle-regulated substrate receptor (F-box protein) for the SCF, is targeted for degradation by APC/C. Furthermore, we establish that Cdh1 is itself a substrate of SCFcyclin F. Cyclin F loss impairs Cdh1 degradation and delays S-phase entry, and this delay is reversed by simultaneous removal of Cdh1. These data indicate that the coordinated, temporal ordering of cyclin F and Cdh1 degradation, organized in a double-negative feedback loop, represents a fundamental aspect of cell-cycle control. This mutual antagonism could be a feature of other oscillating systems

Integrating land use change estimates at state level in the ecoinvent database structure v3.3.
No full textAbstract: Land use change (LUC) emissions have a major importance to agricultural products, especially in countries where agriculture is a relevant economic activity, as in Brazil. Despite its importance, methodologies for LUC estimation are still under debate and there is a lack of regionalized data. To contribute in filling this gap, BRLUC method was developed by Novaes et al (2017), providing estimates of direct LUC and derived CO2 emission rates disaggregated for 64 crops, pasture and forestry for each Brazilian state and a period of 20 years. However, to enhance its potential for use, BRLUC data should be also available in widely used LCA databases. The aim of this article is to present the general structure and adaptations needed to integrate Brazilian LUC estimates from BRLUC into the ecoinvent database v3.3, one of the main international life cycle databases. The main adaptation needs were diagnosed by a joint effort of Embrapa and ecoinvent teams and were: a) the inclusion of new products and land classes (e.g pasture, man-made and forest, intensive), b) segregation of emissions between ?land transformation? and ?land occupation? datasets; c) the conversion of the data structure to the ?land tenure? product model; d) the conversion of LUC substitution percentages into ?land tenure? production volumes and e) the inclusion and adaptation of new emission exchanges. By the automation of the data conversion through an algorithm in R, 418 datasets were generated for incorporation into ecoinvent database, which will increase and ease access to regionalized Brazilian LUC estimates to LCA practitioners
Measurement of the Dependence of the Hadron Production Fraction Ratios and on Meson Kinematic Variables in Proton-Proton Collisions at
No full textThe dependence of the ratio between the B s 0 and B + hadron production fractions, f s / f u , on the transverse momentum ( p T ) and rapidity of the B mesons is studied using the decay channels B s 0 → J / ψ ϕ and B + → J / ψ K + . The analysis uses a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment in 2018 and corresponding to an integrated luminosity of 61.6 fb - 1 . The f s / f u ratio is observed to depend on the B p T and to be consistent with becoming asymptotically constant at large p T . No rapidity dependence is observed. The ratio of the B 0 to B + meson production fractions, f d / f u , is also measured, for the first time in proton-proton collisions, using the B 0 → J / ψ K * 0 decay channel. The result is found to be within 1 standard deviation of unity and independent of p T and rapidity, as expected from isospin invariance
Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays
No full textMeasurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of phi_s=-0.019^{+0.173+0.004}_{-0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found
E-logística: onde Bill Gates e Karl Marx se encontram
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção.As vias, os veículos e os terminais, como componentes básicos do Sistema de Transportes (ST), devem prover a capacidade necessária para a movimentação das cargas e seu manuseio; entretanto, o aumento desta infra-estrutura física, por si só, não é condição suficiente para a melhoria da competitividade regional e nacional. Na era da informação, da globalização, dos mercados voláteis, da economia de escopo, e da ascensão do imaterial, o valor do ST para o Sistema Produtivo (SP) está cada vez menos relacionado com a redução pura e simples do custo das trocas materiais entre processos produtivos, medido, p.ex., pela acessibilidade. Intervenções na infra-estrutura geradas pela avaliação do ST unicamente nestes termos, se favoráveis à competitividade-preço, podem ser até negativas quanto à competitividade-valor, o novo determinante da inserção internacional. É necessário, pois, desenvolver novos métodos para a avaliação de intervenções sobre o ST, que considerem, além dos setores industriais tradicionais, que agregam pouco valor, e cujos fluxos estratégicos são os de matéria e energia, também os setores industriais de ponta, que têm na informação seus fluxos estratégicos, e que agregam alto valor. Para distinguir os requisitos de mobilidade do continuum entre estes dois pólos da organização industrial, este trabalho propõe uma nova conceituação do SP, como o sistema evolutivo que lidera o processo evolucionário universal. Foi o último estágio deste processo, o da integração social, que tornou possível a sistematização da cognição coletiva no sistema científico, bem como da ação coletiva no sistema industrial. O desenvolvimento deste sistema bi-face é impulsionado, em última instância, pelo desejo humano de descobrir ou construir o mundo real à imagem da intuição humana. No entanto, a impossibilidade lógica de racionalizar toda a intuição humana, demonstrada por Gödel, significa que o descasamento entre o que é pensado e o que é produzido pode ser reduzido mas nunca eliminado, e esta tensão essencial constitui a mola fundamental da atividade econômica e de sua dinâmica. O processo infinito de adaptação mútua entre cognição social e ação social explica a crescente especificidade da produção científica, e também a crescente especificidade da produção industrial. A manifestação concreta do desenvolvimento econômico, i.e. uma economia, é uma rede de processos produtivos interligados, pares cognição-ação, que, à medida que progride dos recursos mais genéricos à demanda mais específica, exige uma convergência progressiva entre ação e cognição, e, em conseqüência, entre transporte e comunicação, as faces correspondentes da mobilidade. Com a evolução da produção em massa para a produção diferenciada, a partir do meio da década de 70, isto é demonstrado pela ascendência do moderno conceito de logística, designando o transporte modulado por informação, que já agora evolui para o conceito de logística virtual. No limite, este processo leva à ação em tempo virtual, ao "aniquilamento do espaço pelo tempo" previsto por Karl Marx no século XIX, ou, na versão moderna, à "empresa na velocidade do pensamento" preconizada por Bill Gates
