Cartografia da encenação do "Auto da Barca do Inferno": do processo ao espectáculo

Um dos pressupostos deste trabalho de projecto é de cartografar o trabalho prático de encenação realizado a partir do Auto da Barca do Inferno de Gil Vicente encenado para o Teatro Universitário de Coimbra (T.E.U.C) em 2010 e que constitui a matéria de análise do ensaio aqui sugerido. Neste ensaio levanto algumas questões que alimentaram o processo de criação, e que surgiram do confronto da encenação com um texto clássico, como se poderá verificar no primeiro capítulo. Posteriormente, no segundo capítulo, documento o período de preparação anterior aos ensaios. Finalmente, no terceiro capítulo, defino quais as lógicas que estiveram por trás do processo e que levaram à criação do espectáculo, através da análise à documentação feita diarísticamente no caderno de encenação que dá conta do processo de ensaios até à concretização do espectáculo.

Impact of flavor-changing neutral current top quark interactions on BR(t -> bW)

We study the effect that flavor-changing neutral current interactions of the top quark will have on the branching ratio of charged decays of the top quark. We have performed an integrated analysis using Tevatron and B-factories data and with just the further assumption that the Cabibbo-Kobayashi-Maskawa matrix is unitary, we can obtain very restrictive bounds on the strong and electroweak flavor-changing neutral current branching ratios Br(t -> qX)< 4.0x10(-4), where X is any vector boson and a sum in q=u, c is implied.

Perfil do empreendedor social em Portugal

Com esta investigação pretende-se compreender o perfil do empreendedor social em Portugal, tomando como referência o caso da Bolsa de Valores Sociais. Para estudar as características psicográficas e demográficas que os mentores destes projetos apresentam, a investigação adota um método quantitativo, através de um inquérito por questionário on-line. Para o tratamento e a análise dos dados foram aplicadas técnicas de análise descritiva e de redução de dados (análise fatorial por componentes principais). A investigação sugere que a par de uma componente inata, os fatores demográficos, contingenciais ao indivíduo, influenciam a criação de projetos sociais. Os dados revelam que os empreendedores sociais partilham de traços de personalidade comuns, apresentando um perfil marcado por um elevado nível de extroversão, de abertura à experiência e de conscenciosidade. A análise de dados revela uma forte presença de empreendedores do género feminino e com idades compreendidas entre os 18 e 55 anos. Verifica-se que os empreendedores sociais possuem um elevado nível de formação e em diferentes quadrantes científicos. São indivíduos que antes de se envolverem no lançamento do projeto social na maioria dos casos se encontravam empregados (em particular no setor sem fins lucrativos e no setor empresarial) e satisfeitos com a sua situação ocupacional. A maioria dos indivíduos não possui uma experiência empreendedora anterior (não tendo nem o indivíduo, nem os seus pais, criado previamente qualquer tipo de organização), embora maioritariamente possuam experiência na gestão de organizações. O desenvolvimento do projeto não é precedido por grandes mudanças na vida pessoal do empreendedor, surgindo o contacto com a questão social frequentemente anos antes da decisão de criação da iniciativa e sendo comum que o indivíduo tenha tido um envolvimento anterior em outros projetos sociais.

Search for flavour-changing neutral current top quark decays t → Hq in pp collisions at √s=8 TeV with the ATLAS detector

A search for flavour-changing neutral current decays of a top quark to an uptype quark (q = u, c) and the Standard Model Higgs boson, where the Higgs boson decays to bb¯¯, is presented. The analysis searches for top quark pair events in which one top quark decays to Wb, with the W boson decaying leptonically, and the other top quark decays to Hq. The search is based on pp collisions at s√=8 TeV recorded in 2012 with the ATLAS detector at the CERN Large Hadron Collider and uses an integrated luminosity of 20.3 fb−1. Data are analysed in the lepton-plus-jets final state, characterised by an isolated electron or muon and at least four jets. The search exploits the high multiplicity of b-quark jets characteristic of signal events, and employs a likelihood discriminant that uses the kinematic differences between the signal and the background, which is dominated by tt¯→WbWb decays. No significant excess of events above the background expectation is found, and observed (expected) 95% CL upper limits of 0.56% (0.42%) and 0.61% (0.64%) are derived for the t → Hc and t → Hu branching ratios respectively. The combination of this search with other ATLAS searches in the H → γγ and H → WW *, ττ decay modes significantly improves the sensitivity, yielding observed (expected) 95% CL upper limits on the t → Hc and t → Hu branching ratios of 0.46% (0.25%) and 0.45% (0.29%) respectively. The corresponding combined observed (expected) upper limits on the |λ tcH | and |λ tuH | couplings are 0.13 (0.10) and 0.13 (0.10) respectively. These are the most restrictive direct bounds on tqH interactions measured so far.

Anti-TNF Therapy in the Swiss Inflammatory Bowel Disease G8 Cohort

Background: A nti-TNF d rugs (Infliximab (IFX), Adalimumab (ADA), Certolizumab pegol (CZP)) are effective in inducing and maintaining response a nd remission in i nflammatory bowel disease (IBD). Insufficient response or side effects may lead to a switch o f the anti-TNF d rug. W e aimed to e valuate the frequency and reasons for anti-TNF switches. Methods: Analysis of data from the Swiss Inflammatory Bowel Disease Cohort (SIBDCS). Eighty percent of included patients were recruited in hospitals and 20% from private practice. Results: From 2,058 patients ( 1,172 with Crohn's disease (CD), 842 with ulcerative colitis (UC) and 44 with indeterminate colitis (IC)), 772 received at least one anti-TNF. Forty-eight % of patients w ith CD, 23% with U C, a nd 30% with IC w ere ever treated with an anti-TNF drug. There was no gender difference with respect to the frequency of a nti-TNF treatment. A total of 584 patients (76%) were treated with one, 142 (18%) with two, and 46 (6%) with three anti-TNF (of which 32 were female). A total of 89% patients were treated with IFX, 28% ADA and 13% with CZP. Overall response rate (defined as drop in CDAI >100 points) to anti-TNF was 50%, with best response rates for the first used anti-TNF. Reasons t o switch t he anti-TNF w ere in 11% a primary non-response, in 38% a loss of response and in 36% anti-TNF s ide effects o r intolerance ( reasons for 15% of treatment failures not documented). Conclusion: A nti-TNF d rugs were used in h alf of the CD patients a nd in o ne quarter of U C patients. Anti-TNF d rug switch d ue to insufficient response a nd/or side effects w as necessary in one quarter of IBD patients. IFX was mainly used as first-line therapy. Best response rates were observed for the first used anti-TNF. Following analyses will identify risk median treatment duration as well as risk factors for anti-TNF switch.

Mechanical and elemental characterization of solder joints and welds using a gold-palladium alloy

Purpose. This study was conducted to determine whether newer infrared or laser welding technologies created joints superior to traditional furnace or torch soldering methods of joining metals. It was designed to assess the mechanical resistance, the characteristics of the fractured surfaces, and the elemental diffusion of joints obtained by four different techniques: (1) preceramic soldering with a propane-oxygen torch, (2) postceramic soldering with a porcelain furnace, (3) preceramic and (4) postceramic soldering with an infrared heat source, and (5) laser welding. Material and methods. Mechanical resistance was determined by measuring the ultimate tensile strength of the joint and by determining their resistance to fatigue loading. Elemental diffusion to and from the joint was assessed with microprobe tracings. Scanning electron microscopy micrographs of the fractured surface were also obtained and evaluated. Results. Under monotonic tensile stress, three groups emerged: The laser welds were the strongest, the preceramic joints ranged second, and the postceramic joints were the weakest. Under fatigue stress, the order was as follows: first, the preceramic joints, and second, a group that comprised both postceramic joints and the laser welds. Inspection of the fractographs revealed several fracture modes but no consistent pattern emerged. Microprobe analyses demonstrated minor diffusion processes in the preceramic joints, whereas significant diffusion was observed in the postceramic joints. Clinical Implications. The mechanical resistance data conflicted as to the strength that could be expected of laser welded joints. On the basis of fatigue resistance of the joints, neither infrared solder joints nor laser welds were stronger than torch or furnace soldered joints.

Linee guida della consensus conference dell'ANGP per il monitoraggio plasmatico dei farmaci (TDM) in psichiatria. Aggiornamento 2011 =AGNP consensus guidelines for therapeutic drug monitoring in psychiatry: update 2011

Therapeutic drug monitoring (TDM), i.e., the quantification of serum or plasma concentrations of medications for dose optimization, has proven a valuable tool for the patient-matched psychopharmacotherapy. Uncertain drug adherence, suboptimal tolerability, non-response at therapeutic doses, or pharmacokinetic drug-drug interactions are typical situations when measurement of medication concentrations is helpful. Patient populations that may predominantly benefit from TDM in psychiatry are children, pregnant women, elderly patients, individuals with intelligence disabilities, forensic patients, patients with known or suspected genetically determined pharmacokinetic abnormalities or individuals with pharmacokinetically relevant comorbidities. However, the potential benefits of TDM for optimization of pharmacotherapy can only be obtained if the method is adequately integrated into the clinical treatment process. To promote an appropriate use of TDM, the TDM expert group of the Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie (AGNP) issued guidelines for TDM in psychiatry in 2004. Since then, knowledge has advanced significantly, and new psychopharmacologic agents have been introduced that are also candidates for TDM. Therefore the TDM consensus guidelines were updated and extended to 128 neuropsychiatric drugs. 4 levels of recommendation for using TDM were defined ranging from "strongly recommended" to "potentially useful". Evidence-based "therapeutic reference ranges" and "dose related reference ranges" were elaborated after an extensive literature search and a structured internal review process. A "laboratory alert level" was introduced, i.e., a plasma level at or above which the laboratory should immediately inform the treating physician. Supportive information such as cytochrome P450 substrateand inhibitor properties of medications, normal ranges of ratios of concentrations of drug metabolite to parent drug and recommendations for the interpretative services are given. Recommendations when to combine TDM with pharmacogenetic tests are also provided. Following the guidelines will help to improve the outcomes of psychopharmacotherapy of many patients especially in case of pharmacokinetic problems. Thereby, one should never forget that TDM is an interdisciplinary task that sometimes requires the respectful discussion of apparently discrepant data so that, ultimately, the patient can profit from such a joint effort.

Nitric Oxide Induces the Expression of the Monocarboxylate Transporter MCT4 in Cultured Astrocytes by a cGMP-Independent Transcriptional Activation

The monocarboxylate transporter MCT4 is a proton-linked carrier particularly important for lactate release from highly glycolytic cells. In the central nervous system, MCT4 is exclusively expressed by astrocytes. Surprisingly, MCT4 expression in primary cultures of mouse cortical astrocytes is conspicuously low, suggesting that an external, nonastrocytic signal is necessary to obtain the observed pattern of expression in vivo. Here, we demonstrate that nitric oxide (NO), delivered by various NO donors, time- and dose-dependently induces MCT4 expression in cultured cortical astrocytes both at the mRNA and protein levels. In contrast, NO does not enhance the expression of MCT1, the other astrocytic monocarboxylate transporter. The transcriptional effect of NO is not mediated by a cGMP-dependent mechanism as shown by the absence of effect of a cGMP analog or of a selective guanylate cyclase inhibitor. NO causes an increase in astrocytic lactate transport capacity which requires the enhancement of MCT4 expression as both are prevented by the use of a specific siRNA against MCT4. In addition, cumulated lactate release by astrocytes over a period of 24 h was also enhanced by NO treatment. Our data suggest that NO represents a putative intercellular signal to control MCT4 expression in astrocytes and in doing so, to facilitate lactate transfer to other surrounding cell types in the central nervous system.
