Trabalho e sindicalismo: memória dos 30 anos do movimento de Osasco

Nesta entrevista, Regis de Castro Andrade conta sua experiência na famosa greve de Osasco de 1968, quando era membro do POC e lá trabalhava auxiliando a organização das bases operárias. Realça sua visão de que o movimento teve seus fundamentos na própria organização interna dos operários, com a ajuda dos estudantes, em contraposição a outras que vêem aquele movimento como fruto da articulação do movimento estudantil. Conta também algumas de suas experiências de clandestinidade, prisão e exílio nos anos que se seguiram, até a reorganização do movimento operário no fim da década de 70.In this interview, Regis de Castro Andrade tells us about his experience in the famous strike in Osasco in 1968, in wich he was a member who helped in the organization of the moviment. He enfasizes his point of view that the moviment originated from an internal organization among the employees, who were only helped by the students. This idea is a contrary idea if compared to the statements wich asure that the movement was completelly organized by the students. Andrade also tells us about his experiences in the clandestinity, prison and expatriation wich last until the end of 1970’s

Resistance to Meloidogyne enterolobii in sweet potatoes

The present work was designed to select for sweet potatoes clones (Ipomoea batatas) resistant to Meloidogyne enterolobii (Syn. M. mayaguensis) as well as evaluate the efficiency of the selection methods used by estimating their genetic (VCg) and environmental (VCe) variation coefficients as well as broad sense heritability. A total of 142 sweet potato genotypes were tested, including four commercial varieties (Brazlândia Rosada, Brazlândia Roxa, Brazlândia Branca, and Palmas) as well as the Santa Clara tomato cultivar (utilized as a susceptibility standard). The experimental design was completely randomized blocks, in two repetitions of six plants each. Resistance levels were classified according to the numbers of eggs per gram of roots, the reproduction factor (RF), and the reproduction index (RI) relative to the Santa Clara tomato cultivar. The b= VCg/VCe ratio and broad sense heritability were high in terms of the numbers of eggs per gram of roots, as well as in terms of the reproduction factor and reproduction index, demonstrating the efficiency of the methodology used in the selection of resistant genotypes. Thirty-one sweet potato genotypes resistant to M. enterolobii were identified as having significant potential for continuing the breeding program.The present work was designed to select for sweet potatoes clones (Ipomoea batatas) resistant to Meloidogyne enterolobii (Syn.

Resistência à Helicoverpa armigera em genótipos de tomateiro obtidos do cruzamento de Solanum lycopersicum com Solanum galapagense

The objective of this work was to verify the resistance to the Helicoverpa armigera (Lepidoptera: Noctuidae) caterpillar by tomato genotypes obtained from interspecific crossing of Solanum lycopersicum x S. galapagense, and the association of this resistence with the density of type IV glandular trichomes. Genotypes of the F2 population, obtained from the crossing of S. lycopersicum TOM‑684 x S. galapagense LA‑1401, selected for low and high densities of glandular trichomes, respectively, were subjected to two laboratory resistance tests, one for antibiosis and other for antixenosis. Genotypes of the F2 population, with high density of type IV glandular trichomes (BPX‑486‑17, BPX‑486‑62, BPX‑486‑10, BPX‑486‑46 and BPX‑486‑08), showed higher resistance levels, both by antibiosis and antixenosis, than the genotypes with low‑density glandular trichomes (BPX‑486‑313 and BPX‑486‑383) and the witnesses 'Santa Clara' and TOM‑684. Resistance levels were lower than those of the wild parent LA‑1401.O objetivo deste trabalho foi verificar a resistência à lagarta Helicoverpa armigera (Lepidoptera: Noctuidae), em genótipos de tomateiro obtidos do cruzamento interespecífico de Solanum lycopersicum x S. galapagense, e a associação dessa resistência com a densidade de tricomas glandulares do tipo IV. Genótipos da população F2, derivada do cruzamento S. lycopersicum TOM‑684 x S. galapagense LA‑1401, selecionados quanto à baixa e à alta densidade de tricomas glandulares, respectivamente, foram submetidos a dois testes de resistência à lagarta H. armigera em laboratório, um de antibiose e outro de antixenose. Os genótipos da população F2, com alta densidade de tricomas glandulares do tipo IV (BPX‑486‑17, BPX‑486‑62, BPX‑486‑10, BPX‑486‑46 e BPX‑486‑08), apresentam maiores níveis de resistência, tanto por antibiose quanto por antixenose, do que os genótipos com baixa densidade de tricomas glandulares (BPX‑486‑313 e BPX‑486‑383) e do que as testemunhas 'Santa Clara' e TOM‑684. Os níveis de resistência foram menores do que os do genitor silvestre LA‑1401

Search for direct top-squark pair production in final states with two leptons in pp collisions at √s = 8TeV with the ATLAS detector

A search is presented for direct top-squark pair production in final states with two leptons (electrons or muons) of opposite charge using 20.3 fb−1 of pp collision data at √s = 8 TeV, collected by the ATLAS experiment at the Large Hadron Collider in 2012. No excess over the Standard Model expectation is found. The results are interpreted under the separate assumptions (i) that the top squark decays to a b-quark in addition to an on-shell chargino whose decay occurs via a real or virtual W boson, or (ii) that the top squark decays to a t-quark and the lightest neutralino. A top squark with a mass between 150 GeV and 445 GeV decaying to a b-quark and an on-shell chargino is excluded at 95% confidence level for a top squark mass equal to the chargino mass plus 10 GeV, in the case of a 1 GeV lightest neutralino. Top squarks with masses between 215 (90) GeV and 530 (170) GeV decaying to an on-shell (off-shell) t-quark and a neutralino are excluded at 95% confidence level for a 1 GeV neutralino

Search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s = 8 TeV pp collisions with the ATLAS detector

The results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported. The analysis is performed with proton-proton collision data at s√ = 8 TeV collected with the ATLAS detector at the LHC in 2012 corresponding to an integrated luminosity of 20 fb−1. The lightest supersymmetric particle (LSP) is taken to be the lightest neutralino which only interacts weakly and is assumed to be stable. The stop decay modes considered are those to a top quark and the LSP as well as to a bottom quark and the lightest chargino, where the chargino decays to the LSP by emitting a W boson. A wide range of scenarios with different mass splittings between the stop, the lightest neutralino and the lightest chargino are considered, including cases where the W bosons or the top quarks are off-shell. Decay modes involving the heavier charginos and neutralinos are addressed using a set of phenomenological models of supersymmetry. No significant excess over the Standard Model prediction is observed. A stop with a mass between 210 and 640 GeV decaying directly to a top quark and a massless LSP is excluded at 95% confidence level, and in models where the mass of the lightest chargino is twice that of the LSP, stops are excluded at 95% confidence level up to a mass of 500 GeV for an LSP mass in the range of 100 to 150 GeV. Stringent exclusion limits are also derived for all other stop decay modes considered, and model-independent upper limits are set on the visible cross-section for processes beyond the Standard Model

Search for direct top squark pair production in final states with two leptons in √s=13 TeV pp collisions with the ATLAS detector

The results of a search for direct pair production of top squarks in events with two opposite-charge leptons (electrons or muons) are reported, using 36.1 fb−1 of integrated luminosity from proton–proton collisions at √s=13 TeV collected by the ATLAS detector at the Large Hadron Collider. To cover a range of mass differences between the top squark t~ and lighter supersymmetric particles, four possible decay modes of the top squark are targeted with dedicated selections: the decay t~→bχ~1± into a b-quark and the lightest chargino with χ~1±→Wχ~10 , t~→tχ~10 into an on-shell top quark and the lightest neutralino, the three-body decay t~→bWχ~10 and the four-body decay t~→bℓνχ~10. No significant excess of events is observed above the Standard Model background for any selection, and limits on top squarks are set as a function of the t~ and χ~01 masses. The results exclude at 95% confidence level t~ masses up to about 720 GeV, extending the exclusion region of supersymmetric parameter space covered by previous searches
