Within a wide class of models, the CERN LEP2 lower limit of 95 GeV on the chargino mass implies gluinos are heavier than similar to 300 GeV. In this case electroweak (W) over tilde(1)(W) over tilde(1) production and (W) over tilde(1)(Z) over tilde(2) production are the dominant supersymmerry (SUSY) processes at the Fermilab Tevatron, and the extensively examined isolated trilepton signal From (W) over tilde(1)(Z) over tilde(2) production assumes an even greater importance. We update our previous calculations of the SUSY reach of luminosity upgrades of the Fermilab Tevatron in this channel incorporating (i) decay matrix elements in the computation of the momenta of leptons from chargino and neutralino decays, (ii) the trilepton background from W*Z* and W*gamma* production which, though neglected in previous analyses, turns out to be the dominant background, and finally, (iii) modified sets of cuts designed to reduce these new backgrounds and increase the range of model parameters for which the signal is observable. We show our improved projections for the reach for SUSY of both the Fermilab Main Injector and the proposed TeV33 upgrade. We also present opposite sign same flavor dilepton invariant mass distributions as well as the p(T) distributions of leptons in SUSY trilepton events, and comment upon how the inclusion of decay matrix elements impacts upon the Tevatron reach, as well as upon the extraction of neutralino masses.

Utilizando resultados de trabalho estatístico com base nos dados da Relação Anual de Informações Sociais (RAIS), que permitem caracterizar a indústria de calçados de Nova Serrana (MG) como um sistema local de produção, e nos resultados de pesquisa de campo efetuada em abril de 2002, quando foram realizadas entrevistas e visitas em empresas e instituições locais, o artigo estuda o sistema local de produção de Nova Serrana tanto em termos do sistema como um todo quanto das empresas e instituições que o compõem. O objetivo é produzir, nesses dois níveis de análise, evidências que possam orientar ações públicas e privadas, visando ao aprimoramento do sistema e das empresas locais em duas esferas: (1) produtiva e tecnológica, em seus vários desdobramentos, e (2) institucional e organizacional. Para isso, caracteriza e dimensiona primeiramente o sistema local em termos de sua localização e região de influência, sua logística, população e empregos gerados, história e evolução, estrutura de produção, instituições de apoio, contexto social, cultural e político. em seguida, caracteriza as empresas em termos de tamanho e quanto a: desenvolvimento de produto, sistemas de comercialização, relações cooperativas, interações com fornecedores, fontes de informação para desenvolvimento de produtos e sobre mercados e processos de fabricação, práticas e políticas quanto à qualidade, ao financiamento e a outros aspectos pertinentes ao caso em estudo. Por fim, ressalta os problemas mais relevantes que podem ser objeto de políticas públicas e/ou de ações conjuntas das empresas e instituições locais.

A prescrição abusiva de medicamentos na odontologia constitui um desafio aos programas de saúde pública que visam corrigir a prescrição inadequada de fármacos. Os anti-inflamatórios não esteróides (AINE) podem alteram a eficácia dos anti-hipertensivos, elevando a pressão arterial, sobretudo em pacientes idosos e/ou com hipertensão arterial sistêmica (HAS). O objetivo foi avaliar o nível de conhecimentos dos cirurgiões-dentistas (CD) da rede pública da saúde da Prefeitura Municipal de São José dos Campos (PMSJC) sobre a prescrição de AINE a pacientes com HAS. Trata-se de estudo descritivo, realizado por meio de questionário aplicado aos 92 CD da PMSJC. Os resultados foram analisados estatisticamente utilizando-se os testes de Wald e de Fisher. A associação entre as variáveis foi estudada por meio da razão de chances (OR) com p-valor<0,05. Os resultados mostraram que o nível de conhecimento para a prescrição de AINE para pacientes com HAS foi insuficiente e as interações medicamentosas entre AINE e anti-hipertensivos são desconhecidas pela quase totalidade da amostra. Concluiu-se que os cursos de atualização em odontologia não estão suprindo as necessidades dos CD no âmbito da farmacoterapia.

This research proposes to apply techniques of Mathematics Morphology to extract highways in digital images of high resolution, targeting the upgrade of cartographic products. Remote Sensing data and Mathematical Morphological techniques were integrated in the process of extraction. Mathematical Morphology's objective is to improve and extract the relevant information of the visual image. In order to test the proposed approach some morphological operators related to preprocess, were applied to the original images. Routines were implemented in the MATLAB environment. Results indicated good performances by the implemented operators. The integration of the technologies aimed to implement the semiautomatic extraction of highways with the purpose to use them in processes of cartographic updating.

The objective of this study was to estimate the prevalence of adverse drug reactions (ADR) related to hospital admission of elderly people, identifying the use of potentially inappropriate medication (PIM), the ADR and the risk factors associated with the hospitalization. A cross-sectional study was conducted in a private hospital of São Paulo State, Brazil. All patients aged ≥ 60 years, admitted in the general practice ward in May 2006 were interviewed about the drugs used and the symptoms/complaints that resulted in hospitalization. More than a half (54.5 %) of elderly hospitalizations were related with ADR. The therapeutic classes involved with ADR were: cardiovascular (37.7 %), central nervous (34.6 %) and respiratory (5.7 %). The ADR observed were disorders in circulatory (28.4 %), digestive (20.0 %) and respiratory (18.9 %) tracts. 27 elderly had made PIM and in 20 of them this was the cause of hospitalization. Polypharmacy was an ADR risk factor (p = 0.021).These data allows the healthcare professionals upgrade, qualifying them in pharmcovigilance.

Acoustic Doppler current profilers are currently the main option for flow measurement and hydrodynamic monitoring of streams, replacing traditional methods. The spread of such equipment is mainly due to their operational advantages ranging from speed measurement to the greatest detail and amount of information generated about the hydrodynamics of hydrometric sections. As in the use of traditional methods and equipments, the use of acoustic Doppler profilers should be guided by the pursuit of data quality, since these are the basis for project and management of water resources constructions and systems. In this sense, the paper presents an analysis of measurement uncertainties of a hydrometric campaign held in Sapucaí River (Piranguinho-MG), using two different Doppler profilers - a Rio Grande ADCP 1200 kHz and a Qmetrix Qliner. 10 measurements were performed with each equipment consecutively, following the literature quality protocols, and later, a Type A uncertainty analysis (statistical analysis of several independent observations of the input under the same conditions). The measurements of the ADCP and Qliner presented, respectively, standard uncertainties of 0.679% and 0.508% compared with the averages. These results are satisfactory and acceptable when compared to references in the literature, indicating that the use of Doppler profilers is valid for expansion and upgrade of streamflow measurement networks and generation of hydrological data.

Studies of the structure of excited baryons are key factors to the N* program at Jefferson Lab (JLab). Within the first year of data taking with the Hall B CLAS12 detector following the 12 GeV upgrade, a dedicated experiment will aim to extract the N* electrocouplings at high photon virtualities Q 2. This experiment will allow exploration of the structure of N* resonances at the highest photon virtualities ever achieved, with a kinematic reach up to Q2 = 12 GeV2. This high-Q 2 reach will make it possible to probe the excited nucleon structures at distance scales ranging from where effective degrees of freedom, such as constituent quarks, are dominant through the transition to where nearly massless bare-quark degrees of freedom are relevant. In this document, we present a detailed description of the physics that can be addressed through N* structure studies in exclusive meson electroproduction. The discussion includes recent advances in reaction theory for extracting N* electrocouplings from meson electroproduction off protons, along with Quantum Chromodynamics (QCD)-based approaches to the theoretical interpretation of these fundamental quantities. This program will afford access to the dynamics of the nonperturbative strong interaction responsible for resonance formation, and will be crucial in understanding the nature of confinement and dynamical chiral symmetry breaking in baryons, and how excited nucleons emerge from QCD. © 2013 World Scientific Publishing Company.
