Search for W H associated production in 5.3 fb(-1) of p(p)over-bar collisions at the Fermilab Tevatron

We present a search for associated production of Higgs and W bosons in pp̄ collisions at a center of mass energy of s=1.96 TeV in 5.3 fb-1 of integrated luminosity recorded by the D0 experiment. Multivariate analysis techniques are applied to events containing one lepton, an imbalance in transverse energy, and one or two b-tagged jets to discriminate a potential WH signal from Standard Model backgrounds. We observe good agreement between data and expected backgrounds, and set an upper limit of 4.5 (at 95% confidence level and for mH=115 GeV) on the ratio of the WH cross section multiplied by the branching fraction of H→bb̄ to its Standard Model prediction, which is consistent with an expected limit of 4.8. © 2011 Elsevier B.V.

Marcação e atenuação de múltiplas de superfície livre, processamento e imageamento em dados sísmicos marinhos

O presente trabalho teve como objetivos a análise e atenuação de múltiplas de superfície livre, o processamento e o imageamento de dados sísmicos marinhos visando obter imagens migradas de utilidade à interpretação geológica voltada à exploração de petróleo. Foi dada uma atenção sistemática ao estudo de múltiplas de superfície livre do ponto de vista do filtro de predição baseado na teoria da comunicação com o objetivo de melhor aplicar o filtro WH de deconvolução preditiva, na etapa de processamento, posterior à correção NMO, embora outros métodos possam ser considerados mais competitivos. A identificação e a atenuação de reflexões múltiplas em dados sísmicos reais continua como um grande desafio no processamento de dados sísmicos, uma vez que elas são consideradas como ruído. No entanto, sendo este ruído classificado como coerente, várias técnicas foram desenvolvidas objetivando sua atenuação para evitar erros em cascata nas etapas posteriores como processamento, marcação de eventos, inversão tomográfica, imageamento, e finalmente na interpretação geológica das imagens obtidas. Outro aspecto do trabalho foi estabelecer um fluxograma de processamento-imageamento sendo a atenuação de múltiplas de superfície livre uma etapa central. Foram obtidas seções migradas em tempo e em profundidade onde se permite a interpretação que se deseja. O desenvolvimento deste trabalho foi realizado com os pacotes CWP/SU e MatLab.

Compreender o trabalho na Atenção Primária à Saúde para desenvolver ações em Saúde do Trabalhador: o caso de um município de médio porte

INTRODUCTION: Attention in Worker's Health (WH) integrality incites expansion of Primary Health Care (PHC) actions. So, it is necessary to understand the work carried out at PHC units and its possibilities to subside WH plans and procedures aiming at workers' health integral attention. OBJECTIVE: To present PHC workers' perception concerning WH actions performed in health care units of a mediumsized municipality in the state of São Paulo. METHODOLOGY: data collected through a 20 question-self-assessment questionnaire prepared by the researcher, using descriptive analysis of closed questions and content analysis of open questions. RESULTS: 45% of all workers answered the questionnaire. All health units in the municipality and all the professional categories part of the PHC teams were enclosed. The answers indicated that the PHC personnel, when providing assistance to users, take their jobs into consideration, and that some actions concerning worker's health are carried out at health care units. The respondents also pointed out that their difficulties to perform these actions are much more related to aspects of the system organization and management, than to the particularities of the worker's health area. CONCLUSION: The study indicates that health care worker's working condition is an important issue for the implementation of PHC worker's health actions

An Ultracapacitor-Based No-Break System for Microcomputers

This work aims at presenting a no-break system for microcomputers using ultracapacitors in replacement of the conventional chemical batteries. We analyzed the most relevant data about average power consumption of microcomputers, electrical and mechanical characteristics of ultracapacitors and operation of no-break power circuits, to propose a configuration capable of working properly with a microcomputer switching mode power supply. Our solution was a sixteen-component ultracapacitor bank, with a total capacitance of 350 F and voltage of 10.8 V, adequate to integrate a low-capacity no-break system, capable of feeding a load of 180 Wh, during 75 s. Our proposed no-break increases the reliability of microcomputers by reducing the probability of user data losses, in case of a power grid failure, offering, so, a high benefit-cost ratio. The replacement of the battery by ultracapacitors allows a quick no-break recharge and low maintenance costs, since these modern components have a lifetime longer than the batteries. Moreover, this solution reduces the environmental impact and eliminates the constant recharge of the energy storage device.

Gramaticalização da construção 'é claro que': padrões na fala e na escrita.

In this paper, we investigate the grammatical construction “é claro (que)”, which is characterized as a matrix clause. As it is produced, an argumentative clause is added to the matrix clause in subject position. We analyze oral speech and writing data of contemporary Portuguese and show that the grammatical construction undergoes processes of change, which are identified by desentencialization clauses and grammaticalization process. In addition, by analyzing parameters such as the position of grammatical construction, the presence of copulation and the use of a complementizer, we show that the absence of copulation and a complementizer in the matrix leads to a reduced clause, i.e., a monoclause, and a categorical change of the matrix adjective, which plays the role of functioning adverb.

Bullfrog hemogram under management stress

Stress is one of the major obstacles in frog culture and can be caused by factors such as inappropriate farming systems; inadequate management among other situations. The objective of the present study was to assess the hemogram, erythrogram and leukogram of bullfrogs (L. catesbeianus) when exposed to stress caused by different types of management: density and handling (manipulation), developed in the laboratory and repeated in the field for the appropriate comparisons in a experimental period of 30 days. The density experiment was conducted with four treatments: 70 animals m(-2) (D70); 100 animals m(-2) (D100), Control; 150 animals m(-2) (D150) and 200 animals m(-2) (D200), with 10, 14, 21 and 28 animals/box in the laboratory, respectively. Each treatment was performed with three simultaneous replicates. The handling experiment was conducted with three treatments: Treatment Without Handling (WH); Treatment with Partial Handling (PH) every 15 days and Treatment with Total Handling (TH) every 15 days. Each treatment was performed with four simultaneous replications. The methodology of the blood analysis followed international recommendations. In the present study we could observe that the animals of the field experiment did not reflect the same stress response observed in the laboratory in both experiment, which demonstrated the plasticity of these animals.
