Equity Research : Portugal Telecom

In the distinct fields of valuation, and in particular in Equity Research, theory and practice should be accurately combined as way to obtain the most consistent outcome which adheres to reality. The present dissertation aims at answering this need through bridging the review of relevant literature with the valuation of the leading telecommunications operator Portugal Telecom in practical terms. The year-end 2012 price target derived from the company’s stock is 5,01Euro per share, implying a Buy recommendation. Caixa Banco de Investimento’s research is additionally analyzed and used as basis for comparison for both the methodologies followed and results yielded

Glyphosate application associated to different concentrations of non-purified residue of biodiesel production

A busca por fontes energéticas renováveis tem estimulado a implantação de unidades de produção de biodiesel no Brasil. Porém, para que o biodiesel seja considerado plenamente sustentável, deve-se encontrar destinos adequados para os resíduos de sua produção, com destaque para a glicerina bruta. Assim sendo, este trabalho foi desenvolvido com o objetivo de avaliar a eficácia do herbicida glyphosate no controle de plantas daninhas quando associado a diferentes concentrações de resíduo não purificados da produção de biodiesel. Dois experimentos foram realizados, um em viveiro experimental, utilizando o capim-amargoso (Digitaris insularis) como bioindicador; e outro em campo, avaliando a comunidade natural de plantas daninhas. A adição de resíduo da produção de biodiesel à calda de pulverização não elevou a eficácia do herbicida glyphosate no controle do capim-amargoso. Ainda, foi observada redução na eficácia do glyphosate após adição de resíduo à calda de pulverização em doses iguais ou superiores a 0,6% v/v. Não foram encontrados resultados que justifiquem a adoção de resíduo da produção de biodiesel como adjuvante agrícola. Os pontos positivos observados foram mínimos, sem consistência entre espécies ou momentos de aplicação, permanecendo o glyphosate puro como a melhor opção de aplicação e recomendação.Searching for renewable energy sources has motivated the development of biodiesel production units in Brazil. However, for biodiesel being considered fully sustainable, suitable destinations for its production waste should be found, especially for crude glycerin. Therefore, this work was developed to evaluate glyphosate herbicide efficacy on weed control when combined to different concentrations of non-purified residue of biodiesel production. Two experiments were carried out, one in an experimental plant nursery, using sourgrass (Digitaria insularis) as bioindicator, and another one in field condition, assessing the natural weed community. Adding biodiesel production waste to the spray mix solution has not increased glyphosate efficacy in controlling sourgrass. Furthermore, there was a reduction in glyphosate effectiveness after addition of waste to the spray mix solution at doses equal to or higher than 0.6% v/v. No results were found justifying the adoption of biodiesel production residue as an agricultural adjuvant. Positive points observed were minimal, with no consistency between species or application times, and glyphosate remains as the best application and recommendation option

Glyphosate application associated to non-purified residue of biodiesel production: analysis of different prototypes

O herbicida glyphosate é um defensivo agrícola de grande importância mundial. Neste sentido, diversos trabalhos têm sido desenvolvidos no intuito de selecionar adjuvantes que elevem a eficácia do produto. Dois experimentos foram realizados com o objetivo de avaliar a eficácia do herbicida glyphosate quando associado a diferentes protótipos experimentais de adjuvantes agrícolas, elaborados a partir de resíduos não-purificados da produção de biodiesel. Foi utilizado resíduo bruto da produção de biodiesel, bem como sua diluição em água, adição de sulfato de amônio, KOH e/ou óleo de soja. Avaliou-se o controle da corda-de-viola (Ipomoea triloba L.) em viveiro experimental, bem como a infestação de plantas daninhas em condição de campo. Em geral, a presença de protótipos de adjuvante na calda do herbicida glyphosate não resultou em incrementos de controle em nenhuma condição experimental, porém, também não prejudicou a eficácia do produto.Glyphosate is an agricultural pesticide of great importance in the world. In this sense, several studies have been developed in order to select adjuvants which elevate the efficacy of the product. Two experiments were performed with the goal to evaluate the efficacy of the glyphosate herbicide when associated to different experimental prototypes of agricultural adjuvants, elaborated from non-purified residue ofbiodiesel production. Gross residue from the biodiesel production was used, as well as its dilution in water, and addition of ammonium sulfate, KOH and/or soybean oil. Control of morning glory (Ipomoea triloba L.) was evaluated in experimental plant nursery, as well as the infestation of weeds in the field condition. In general, the presence of adjuvant prototypes in glyphosate herbicide spray did not result in an increase of the control in any experimental condition, as well as, it did not reduce the efficiency of the product

Thrombus aspiration in patients with ST-elevation myocardial infarction: results of a national registry of interventional cardiology

BACKGROUND: We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in 'real-world' settings. METHODS: We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006-2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). RESULTS: We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54-1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35-0.98; 3500 patients). CONCLUSIONS: The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensity-score matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI..info:eu-repo/semantics/publishedVersio

Highlights of the Brazilian Thoracic Association guidelines for interstitial lung diseases

Interstitial lung diseases (ILDs) are heterogeneous disorders, involving a large number of conditions, the approach to which continues to pose an enormous challenge for pulmonologists. The 2012 Brazilian Thoracic Association ILD Guidelines were established in order to provide Brazilian pulmonologists with an instrument that can facilitate the management of patients with ILDs, standardizing the criteria used for the diagnosis of different conditions and offering guidance on the best treatment in various situations. The objective of this article was to briefly describe the highlights of those guidelines.As doenças pulmonares intersticiais (DPIs) são afecções heterogêneas, envolvendo um elevado número de condições, cuja abordagem ainda é um grande desafio para o pneumologista.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Measurement of the differential cross-section of B+B^{+} meson production in pp collisions at s\sqrt{s} = 7 TeV at ATLAS

The production cross-section of B+ mesons is measured as a function of transverse momentum pT and rapidity y in proton--proton collisions at center-of-mass energy sqrt(s) = 7 TeV, using 2.4 fb-1 of data recorded with the ATLAS detector at the Large Hadron Collider. The differential production cross-sections, determined in the range 9<pT<120 GeV and y<2.25, are compared to next-to-leading-order theoretical predictions.Peer Reviewe

Dynamics of isolated-photon plus jet production in pp collisions at (s)=7\sqrt(s)=7 TeV with the ATLAS detector

The dynamics of isolated-photon plus jet production in pp collisions at a centre-of-mass energy of 7 TeV has been studied with the ATLAS detector at the LHC using an integrated luminosity of 37 pb^-^1. Measurements of isolated-photon plus jet bin-averaged cross sections are presented as functions of photon transverse energy, jet transverse momentum and jet rapidity. In addition, the bin-averaged cross sections as functions of the difference between the azimuthal angles of the photon and the jet, the photon-jet invariant mass and the scattering angle in the photon-jet centre-of-mass frame have been measured. Next-to-leading-order QCD calculations are compared to the measurements and provide a good description of the data, except for the case of the azimuthal opening angle.Peer Reviewe
