Métodos O processo de adaptação foi realizado em cinco etapas: tradução, retradução, avaliação da equivalência entre a retradução e a escala original, elaboração de uma versão pré-teste e aplicação na população-alvo composta por 16 idosos (56 a 80 anos), com quatro anos mínimos de escolaridade. Resultados A versão adaptada não gerou problemas de compreensão, aceitabilidade ou impacto emocional negativo. Conclusão Este trabalho torna disponível a primeira versão em Português da LCB, uma escala que tem sido particularmente utilizada para avaliar o tipo de locus de controle (LoC) no que concerne ao prognóstico de tratamentos em saúde mental.

Produção de latex por clones de seringueira (Hevea spp) no planalto e litoral do Estado de São Paulo

A partir dos dados de produção em volume de látex, extraído de clones de seringueira (Hevea spp.), durante 17 anos no Centro Experimental Theodureto de Camargo (Campinas, região de planalto) e 16 anos na Estação Experimental Vale do Ribeira (Pariquera-Açú, região litorânea), ambos pertencentes ao Instituto Agro_ nômico do Estado de São Paulo, Campinas, foi estudado o comportamento da produção de cada clone. Pelo teste de Tukey foi possível determinar, considerando-se as duas regiões, os melhores clones quanto ao potencial produtivo dado pelas médias de produção. Entre os melhores encontram-se: RRIM 600 e BSA 20. 0 primeiro pertence a Estação Experimental e o segundo ao Centro Experimental. Em seguida tem-se um grupo intermediário, formado pelos clones CA 1328, Tjir 16, C 228, RRIm 526, C 297, LCB 510 e Fx 25, todos pertencentes ao Centro Experimental. Os menos produtivos foram: Fx 25, C 290 e RRIM 600, todos pertencentes ao Centro Experimental. 0 clone Fx 25 apresentou baixa produção nas regiões estudadas, porém sua produção na Estação Experimental foi superior à do Centro Experimental, bem como às dos clones C 290 e RRIM 600, cultivados no Centro Experimental.

Adaptabilidade e estabilidade de acessos de uma coleção nuclear de arroz

O objetivo deste trabalho foi determinar o potencial produtivo e a interação entre genótipos e ambientes em 550 acessos da Coleção Nuclear de Arroz da Embrapa. O desempenho, a adaptação e a estabilidade produtiva de cada genótipo foram avaliados por meio da metodologia de análise dos efeitos principais aditivos e interações multiplicativas (AMMI), em nove experimentos de campo, realizados em seis Estados, em condição de sequeiro e irrigada, durante três anos agrícolas. Foi realizada a análise por meio de modelos lineares mistos, e as estimativas de componentes de variância foram obtidas pelo método de máxima verossimilhança residual (REML), com aplicação do procedimento de melhor predição linear não viesada (BLUP) para a predição dos valores genéticos dos efeitos aleatórios (EBLUP) associados a cada um dos acessos. O grupo de acessos com melhor desempenho foi o de linhagens e cultivares brasileiras (LCB), conforme o esperado. No entanto, foram identificadas variedades tradicionais (VT) entre os genótipos mais produtivos, o que mostra o potencial deste grupo de germoplasma em contribuir com novas fontes de variabilidade genética para programas de melhoramento. Foram identificados acessos superiores quanto à estabilidade, adaptabilidade e produtividade de grãos, entre os quais destacam-se CA880078, CA840182 e CNA00091.

Laitteen elinkaaritietoon perustuvien asiakasarvopohjaisten palveluiden kehittäminen

Työssä tutkitaan asiakasarvopohjaisten elinkaaritietoon perustuvien palveluiden kehittämistä. Tavoitteena on löytää asiakasarvo tuulivoimaliiketoiminnassa, selvittää mitä palveluja voidaan tuottaa elinkaaritietoon pohjautuen ja millainen kehitysprosessi palveluille ABB:n ympäristössä voidaan kuvata. Tutkimusongelmaa on tarkasteltuLCB-tutkimusprojektin tulosten ja kirjallisuuden pohjalta. Teoriat voidaan jakaa kolmeen osaan, asiakasarvoon, dataan ja kehitysprosessiin. Ensimmäisessä osassa keskitytään tarjoaman muutokseen, rooleihin liiketoimintaverkostossa ja asiakasarvon laskennalliseen määritykseen. Toisessa osassa keskitytään datan palveluksi jalostamiseen ja kolmannessa palvelun kehitysprosessin tutkimiseen. Tutkimustuloksia on verifioitu case-tutkimuksen avulla ja erästä asiakasta on lähestytty case-tapauksena haastattelun avulla. Asiakas on profiloitu haastattelun perusteella tavoitteena löytää asiakasarvo ja kiinnostus uusia palveluja kohtaan. Uusia palveluita on kehitetty sekä eksplisiittisen että hiljaisen tiedon pohjalta. Näiden pohjalta on luotu toimivia palvelukonsepteja ja ideointivaiheen kehitysprosessi on dokumentoitu. Työstä on tehty kaksi eri versiota, joista tämä on suppeampi.

Eficacia de la ayuda al desarrollo: el debate político sobre la cooperación internacional en Colombia (Tema Central)

Si bien un importante referente sobre la agenda de la eficacia en el mundo de la cooperación lo constituye la Declaración de París (DP) y posteriormente la Agenda de Acción de Accra (AAA), en este ensayo se traerá a colación otro proceso en la búsqueda de eficacia de la cooperación internacional en Colombia; el proceso Londres, Cartagena, Bogotá (LCB). El objetivo de este ensayo consiste en poner en discusión los posibles avances y aportes al desarrollo en Colombia desde la agenda de eficacia de la ayuda. Así como también destacar las críticas que en dicho proceso de implementación se generan desde actores afectados o involucrados en el proceso como las organizaciones de la sociedad civil (OSC).

Quantization of the electromagnetic field outside static black holes and its application to low-energy phenomena

We discuss the Gupta-Bleuler quantization of the free electromagnetic field outside static black holes in the Boulware vacuum. We use a gauge which reduces to the Feynman gauge in Minkowski spacetime. We also discuss its relation with gauges used previously. Then we apply the low-energy sector of this held theory to investigate some low-energy phenomena. First, we discuss the response rate of a static charge outside the Schwarzschild black hole in four dimensions. Next, motivated by string physics, we compute the absorption cross sections of low-energy plane waves for the Schwarzschild and extreme Reissner-Nordstrom black holes in arbitrary dimensions higher than three.

Semiclassical approach to black hole absorption of electromagnetic radiation emitted by a rotating charge

We consider an electric charge, minimally coupled to the Maxwell field, rotating around a Schwarzschild black hole. We investigate how much of the radiation emitted from the swirling charge is absorbed by the black hole and show that most of the photons escape to infinity. For this purpose we use the Gupta-Bleuler quantization of the electromagnetic field in the modified Feynman gauge developed in the context of quantum field theory in Schwarzschild spacetime. We obtain that the two photon polarizations contribute quite differently to the emitted power. In addition, we discuss the accurateness of the results obtained in a full general relativistic approach in comparison with the ones obtained when the electric charge is assumed to be orbiting a massive object due to a Newtonian force.

Non-relativistic spacetimes with cosmological constant

Recent data on supernovae favour high values of the cosmological constant. Spacetimes with a cosmological constant have non-relativistic kinematics quite different from Galilean kinematics. de Sitter spacetimes, vacuum solutions of Einstein's equations with a cosmological constant, reduce in the non-relativistic limit to Newton-Hooke spacetimes, which are non-metric homogeneous spacetimes with non-vanishing curvature. The whole non-relativistic kinematics would then be modified, with possible consequences to cosmology, and in particular to the missing-mass problem.

Is the equivalence for the response of static scalar sources in the Schwarzschild and Rindler spacetimes valid only in four dimensions?

It was shown recently that in four dimensions scalar sources with fixed proper acceleration minimally coupled to a massless Klein-Gordon field lead to the same responses when they are (i) uniformly accelerated in Minkowski spacetime (in the inertial vacuum) and (ii) static in the Schwarzschild spacetime (in the Unruh vacuum). Here we show that this equivalence is broken if the spacetime dimension is more than four.

Scaler radiation emitted from a source rotating around a black hole

We analyse the scalar radiation emitted from a source rotating around a Schwarzschild black hole using the framework of quantum held theory at the tree level. We show that for relativistic circular orbits the emitted power is about 20-30% smaller than what would be obtained in Minkowski spacetime. We also show that most of the emitted energy escapes to infinity. Our formalism can readily be adapted to investigate similar processes.

Intestinal IgG uptake by small intestine of goat kid fed goat or lyophilized bovine colostrum

The immunoglobulin G (IgG) uptake and enterocyte nucleus position in the villous were studied in newborn goat kids fed goat or lyophilized bovine colostrum. Two groups of 15 newborn goat kids, each received 5% of body weight of goat colostrum (GC) or lyophilized bovine colostrum (LBC) containing 55 mg/mL of immunoglobulin G (IgG) at 0, 7 and 14 h of life. Three animals were sampled just after birth, receiving no colostrum intake, to be used as control. Samples of duodenum, medium jejunum and ileum were collected at 0, 18, 36 and 96 h of life. IgG vacuoles were not observed in the duodenum throughout the experiment regardless of all the experimental time points. In this segment, at 0, 18 and 36 h of life, nuclei were found in the apical, medial and basal positions in the enterocytes, and localized in the upper, medial and lower parts in the villous, respectively. At 96 h, a basal nuclei position was observed in the enterocytes, throughout the villous. In jejunum, IgG vacuoles were distributed along the villous at 18 and 36 h. In this segment at Oh the nuclei were positioned predominantly apically in the enterocytes, throughout the villous. At 18 and 36 h, no consistent nuclei pattern was verified: however at 96 h, the nuclei were positioned basally in the enterocytes, throughout the jejunal villous. In the ileum at 0, 18 and 36 h, a great number of vacuoles without IgG were verified in the medial-apical part of the villous. In this segment, at Oh of life and 96 h of life, the predominance of basal nuclei was observed. Nuclei were positioned in medial-apically part of the ileal enterocytes in the upper part of the villous at 18 and 36 h. It was found that the jejunal epithelium was the most important segment related to absorption process. The IgG absorption and nucleus position in the newborn goats were dependent on the small intestine segments and experimental time points, regardless of the colostrum source. GC or LCB. Considering the IgG uptake mechanism observed in the present study, the lyophilized bovine colostrum might be used instead of goat colostrum. (C) 2011 Elsevier B.V. All rights reserved.

MEGARA: the future IFU and MOS of the 10.4 M GTC

In these proceedings we summarize the characteristics and current status of MEGARA, the future optical IFU and MOS for the 10.4 m GTC. MEGARA is being built by a Consortium led by the UCM (Spain) that also includes the INAOE (Mexico), the IAA-CSIC (Spain) and the UPM (Spain). The MEGARA IFU offers two different bundles, one called LCB with a field-of-view of 14 x 12 arcsec^2 and a spaxel size of 0.685 arcsec yielding spectral resolutions between R=6000-19000 and another one called SCB covering 10 x 8 arcsec^2 with 0.48 arcsec spaxels and resolutions R=8000-25000. The MOS component allows observing up to 100 targets in 3.5x3.5 arcmin^2. In September 2010 MEGARA was selected as the next optical spectrograph for GTC. Its PDR is scheduled for March 2012 with First Light on 2015.

Coagent Modified Polypropylene Prepared by Reactive Extrusion: A New Look Into the Structure-Property Relations of Injection Molded Parts

Peroxide-mediated reactive extrusion of linear isotactic polypropylene (L-PP) was conducted in the presence of trimethylolpropane trimethacrylate (TMPTMA) and triallyl trimesate (TAM) coagents, using a twin screw extruder. The resulting coagent-modified polypropylenes (CM-PP) had higher viscosities and elasticities, as well as increased crystallization temperature compared to PP reacted only with peroxide (DCP-PP). Additionally, deviations from terminal flow, and strain hardening were observed in PP modified with TAM, signifying the presence of long chain branching (LCB). The CM-PP formulations retained the modulus and tensile strength of the parent L-PP, in spite of their lower molar mass and viscosities, whereas their elongation at break and the impact strength were better. This was attributed to the finer spherulitic structure of these materials, and to the disappearance of the skin-core layer in the injection molded specimens.
