Podredumbre negra en Yuca amarilla (Manihot esculenta Crantz) causada por Thielaviopsis basicola

96-108Por primera vez se reporta al hongo Thielaviopsis basicola (Berk. Broome) Ferris, como causa de podredumbre negra en las raíces comestibles de yuca amarilla. Para aislar el patógeno se utilizaron cebos preparados con raíces frescas y sanas de zanahoria. El hongo produjo sus estructuras reproductivas sobre raíces de yuca infectadas naturalmente y de zanahoria inoculadas experimentalmente. La identidad del organismo se determinó sobre la base de las características morfométricas de sus estructuras reproductivas y a través de análisis molecular por secuenciación de la región génica del rDNA, incluyendo las regiones variables ITS1 e ITS2. Pruebas de patogenicidad y reaislamientos confirmaron los postulados de Koch

Obstáculos epistemológicos para el aprendizaje de la estructura y el funcionamiento del Sistema Circulatorio Sanguíneo Humano (SCSH) en estudiantes de grado séptimo y décimo: un constructo teórico desde la perspectiva sistémica

Esta investigación abordó la problemática del aprendizaje de conceptos científicos a través de la identificación de los obstáculos epistemológicos asociados con la comprensión de la estructura y el funcionamiento del Sistema Circulatorio Sanguíneo Humano (SCSH) por parte de estudiantes de séptimo y décimo en dos colegios oficiales. El estudio de las concepciones sirvió como insumo para el diseño de una propuesta didáctica y teórica que incorpora la perspectiva sistémica. El enfoque metodológico utilizado fue cualitativo a través del método de teoría fundamentada, la recopilación de la información se realizó de forma directa a través de la aplicación de dos instrumentos tipo cuestionario, cuyo diseño se llevó a cabo por etapas. El análisis de las concepciones de los estudiantes permitió identificar obstáculos epistemológicos que limitan la comprensión del SCSH, pero a su vez sirven de base para avanzar en el aprendizaje pues están relacionados con el mecanismo que utilizan los estudiantes para interpretar la realidad, dentro de estos obstáculos encontramos la utilización de modelos de explicación teleológicos finalistas, predominio de un nivel de representación intuitivo basado en un pensamiento causal-lineal y la inadecuada interpretación del material didáctico usado para la divulgación del saber científico que en ocasiones refuerza concepciones contrarias a las científicas. La propuesta teórica y didáctica desde lo sistémico permite integrar diferentes ramas del conocimiento logrando una serie de interacciones que podrían permitir romper con el predominio del pensamiento causal-lineal antes mencionado.This research addressed the problem of learning scientific concepts through the identification of epistemological obstacles associated to the understanding of the structure and functioning of the Human Blood Circulatory System (HBCS) by seventh and tenth grade students in two public schools. The study of the conceptions served as an input for the design of a didactic and theoretical proposal that incorporates the systemic perspective. It was used the qualitative methodological approach through the grounded theory method. The collection of information was carried out directly through the application of two questionnaire type instruments, whose design was carried out in stages. The analysis of the students' conceptions allowed us to identify the epistemological obstacles that limit the understanding of the HBCS, but they serve as well as a base to advance in the learning because they are related to the mechanism that students use to interpret reality. Within these obstacles we find the use of finalist teleological explanation models, predominance of a level of intuitive representation based on linear-causal thinking and the inadequate interpretation of didactic material used for the dissemination of scientific knowledge that sometimes reinforces conceptions that are contrary to the scientific ones. The theoretical and didactic proposal from the systemic allows to integrate different branches of knowledge, achieving a series of interactions that could break with the predominance of the linear-causal thought mentioned above.Magíster en EducaciónMaestrí

The impact of gender-role-orientations on subjective career success: a multilevel study of 36 societies

International audienceWe investigate the relationships between gender-role-orientation (i.e., androgynous, masculine, feminine and undifferentiated) and subjective career success among business professionals from 36 societies. Drawing on the resource management perspective, we predict that androgynous individuals will report the highest subjective career success, followed by masculine, feminine, and undifferentiated individuals. We also postulate that meso-organizational culture and macro-societal values will have moderating effects on gender role's impact on subjective career success. The results of our hierarchical linear models support the hypothesized hierarchy of the relationships between gender-role-orientations and subjective career success. However, we found that ethical achievement values at the societal culture level was the only variable that had a positive moderating impact on the relationship between feminine orientation and subjective career success. Thus, our findings of minimal moderation effect suggest that meso- and macro-level environments may not play a significant role in determining an individual's perception of career success

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of √s = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pT≥20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60≤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2≤{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal

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

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

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
