Enzimas e vitaminas do embrião e da amêndoa do babaçu

Analisou-se separadamente amêndoas e embriões de cocos de babaçu, (Orbignya martiana) para estudar algumas de suas enzimas e vitaminas tendo em vista seu maior consumo na alimentação. Detetou-se sistematicamente duas frações protéicas fortemente coradas e uma que aparece em algumas amostras e não aparece em outras. Das enzimas constatou-se três leucino-aminoptidase málicas (MDH1, MDH2, MDH3) e duas deidrogenase do glicerol -3-fosfato (GPD). Quanto às vitaminas constatou-se existir em 100 gramas de material: no embrião 0.100mg de riboflovina, 3,4 de vit. C e 30 de alfa-tocoferol; a amêndoa tem pouco menos da metade das vitaminas B1 e C.

Blast loading of masonry infills: testing and simulation

This work intends to present a newly developed test setup for dynamic out-of-plane loading using underWater Blast Wave Generators (WBWG) as loading source. Underwater blasting operations have been, during the last decades, subject of research and development of maritime blasting operations (including torpedo studies), aquarium tests for the measurement of blasting energy of industrial explosives and confined underwater blast wave generators. WBWG allow a wide range for the produced blast impulse and surface area distribution. It also avoids the generation of high velocity fragments and reduces atmospheric sound wave. A first objective of this work is to study the behavior of masonry infill walls subjected to blast loading. Three different masonry walls are to be studied, namely unreinforced masonry infill walls and two different reinforcement solutions. These solutions have been studied previously for seismic action mitigation. Subsequently, the walls will be simulated using an explicit finite element code for validation and parametric studies. Finally, a tool to help designers to make informed decisions on the use of infills under blast loading will be presented.

Measurements of the W production cross sections in association with jets with the ATLAS detector

This paper presents cross sections for the production of a W boson in association with jets, measured in proton--proton collisions at s√=7 TeV with the ATLAS experiment at the Large Hadron Collider. With an integrated luminosity of 4.6fb−1, this data set allows for an exploration of a large kinematic range, including jet production up to a transverse momentum of 1 TeV and multiplicities up to seven associated jets. The production cross sections for W bosons are measured in both the electron and muon decay channels. Differential cross sections for many observables are also presented including measurements of the jet observables such as the rapidities and the transverse momenta as well as measurements of event observables such as the scalar sums of the transverse momenta of the jets. The measurements are compared to numerous QCD predictions including next-to-leading-order perturbative calculations, resummation calculations and Monte Carlo generators.

Measurement of transverse energy-energy correlations in multi-jet events in pp collisions at s√=7 TeV using the ATLAS detector and determination of the strong coupling constant αs(mZ)

High transverse momentum jets produced in pp collisions at a centre of mass energy of 7 TeV are used to measure the transverse energy--energy correlation function and its associated azimuthal asymmetry. The data were recorded with the ATLAS detector at the LHC in the year 2011 and correspond to an integrated luminosity of 158 pb−1. The selection criteria demand the average transverse momentum of the two leading jets in an event to be larger than 250 GeV. The data at detector level are well described by Monte Carlo event generators. They are unfolded to the particle level and compared with theoretical calculations at next-to-leading-order accuracy. The agreement between data and theory is good and provides a precision test of perturbative Quantum Chromodynamics at large momentum transfers. From this comparison, the strong coupling constant given at the Z boson mass is determined to be αs(mZ)=0.1173±0.0010 (exp.) +0.0065−0.0026 (theo.).

Factoriality and the pin-reutenauer procedure

We consider implicit signatures over finite semigroups determined by sets of pseudonatural numbers. We prove that, under relatively simple hypotheses on a pseudovariety V of semigroups, the finitely generated free algebra for the largest such signature is closed under taking factors within the free pro-V semigroup on the same set of generators. Furthermore, we show that the natural analogue of the Pin-Reutenauer descriptive procedure for the closure of a rational language in the free group with respect to the profinite topology holds for the pseudovariety of all finite semigroups. As an application, we establish that a pseudovariety enjoys this property if and only if it is full.

Enhancing longevity of pacemakers through reprogramming. Underutilization and cost-effectiveness

OBJECTIVE: This study was performed to observe the number of pacemakers that had never been reprogrammed after implantation, and the effect of optimised output programming on estimated longevity of pulse generators in patients with pacemaker METHODS: Sixty patients with Teletronics Reflex pacemakers were evaluated in a pacemaker clinic, from the time of the beginning of its activities, in June 1998, until March 1999. Telemetry was performed during the first clinic visit, and we observed how many pulse generators retained nominal output settings of the manufactures indicating the absence of reprogramming until that date. After evaluation of the capture threshold, reprogramming of pacemakers was performed with a safety margin of 2 to 2.5:1, and we compared the estimated longevity based on battery current at the manufacturer's settings with that based on settings achieved after reprogramming. RESULTS: In 95% of the cases, the original programmed setting was never reprogrammed before the patients attended the pacemaker clinic. Reprogramming the pacemaker prolonged estimated pulse generator life by 19.7±15.6 months (35.5%). CONCLUSION: The majority of the pacemakers evaluated had never been reprogrammed. Estimated pulse generator longevity can be prolonged significantly, using this simple, safe, efficacious, and cost-effective procedure.

Qualidade de Vida e Cardiopatia Congenita na Infancia e Adolescencia

Os avanços nas técnicas de cirurgia cardíaca e o diagnóstico precoce têm possibilitado maior sobrevida de indivíduos com cardiopatias congênitas. A investigação da qualidade de vida em crianças e adolescentes com cardiopatias congênitas fornece informações complementares aos dados clínicos que podem auxiliar na tomada de decisão dos profissionais de saúde. Embora muitos estudos tenham sido realizados para investigar a qualidade de vida de crianças e adolescentes com cardiopatias congênitas, os resultados mostram-se contraditórios. Enquanto alguns estudos revelam que as cardiopatias podem impactar a qualidade de vida, outros descrevem melhor percepção da qualidade de vida entre crianças e adolescentes cardiopatas quando comparados com controles saudáveis. O objetivo deste estudo é revisar a literatura sobre a avaliação da qualidade de vida relacionada à saúde em crianças e adolescentes com cardiopatias congênitas, de forma a sistematizar o conhecimento existente sobre esse tema na atualidade. Observa-se que as pesquisas procuram investigar aspectos relacionados à personalidade do paciente cardiopata, às estratégias de enfrentamento utilizadas por ele e ao suporte social percebido, visando à melhor compreensão da associação de tais variáveis com o nível de qualidade de vida nessa população.
