Divergência genética entre linhagens de feijão-caupi subclasse comercial fradinho.

O feijão-caupi (Vigna unguiculata (L.) Walp.) é uma espécie de grande importância socioeconômica e alimentar, principalmente em países em desenvolvimento como o Brasil, sobretudo nas regiões Norte e Nordeste. O trabalho foi conduzido no campo experimental da Embrapa Meio-Norte, Teresina, PI, em setembro de 2010, objetivou-se estimar a divergência genética entre 109 linhagens feijão-caupi de ciclo precoce, da subclasse comercial fradinho. O delineamento experimental foi o de blocos aumentados de Federer, com cindo blocos. A partir dos dados quantitativos pode-se observar que os genótipos mais divergentes de acordo com as distância Euclidiana foram MNC06-907-8, MNC06-907-19, MNC06-898-6; MNC06-907-8

Uso dos descritores qualitativos para a estimativa da divergência genética entre linhagens de feijão-caupi subclasse comercial fradinho.

O feijão-caupi (Vigna unguiculata (L.) Walp.) é uma das espécies cultivadas que apresenta ampla capacidade de adaptação. No Brasil, esta cultura apresenta grande importância para as regiões Norte e Nordeste, devido à tradição no seu cultivo, comércio e consumo (ROCHA et al., 2009). O presente trabalho teve como objetivo estimar a divergência genética entre 109 linhagens de feijão-caupi subclasse comercial fradinho. O trabalho foi conduzido no campo experimental da Embrapa Meio-Norte, Teresina, PI, em de setembro de 2010 Foram avaliados 37 descritores morfológicos relacionados à planta, à flor, à vagem e a semente. O delineamento experimental adotado foi o de Blocos Aumentados de Federer, com cinco blocos. Para as características qualitativas o agrupamento de Tocher possibilitou a distribuição dos genótipos avaliados em grupos, dentre os quais os mais distantes geneticamente foram os grupos II e V; e V e VIII

Caries associated with orthodontic care part 2: management

It is recognized that wearing an orthodontic appliance increases the caries risk of the individual. The prevalence of demineralization has been reported to be as high as 73%. When demineralization occurs a number of treatments exist: fluoride application, acid microabrasion, casein phosphopeptide-amorphous calcium phosphate (CCP-ACP), resin infiltration and self-assembling peptides. Of these, topical fluoride has the most evidence to support its use. CPD/Clinical Relevance: Demineralization is the most common complication of orthodontic care. The clinician should understand how to manage this when it occurs

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal

Standalone vertex finding in the ATLAS muon spectrometer

A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson
