  • Jogos de Fortuna ou Azar - Criminalização ou Descriminalização? Uma questão "simples" com uma resposta complexa
    Publication . Esteves, Sílva Ângela Oliveira dos Reis; Dias, Jorge de Figueiredo
    Os jogos de fortuna ou azar os quais dependem exclusiva ou fundamentalmente da sorte, designadamente os jogos de casino, estão presentes no cotidiano português, quer seja de forma legal ou ilegal. Ao discutir-se a possibilidade de existir uma descriminalização da sua exploração sem a devida autorização, não se pode deixar de considerar as implicações que estariam subjacentes a esta. Os reflexos da descriminalização poderiam deixar sem proteção bens jurídicos constitucionalmente protegidos, além de que a exploração ilícita de jogos de fortuna ou azar, estará associada a outros crimes como a fraude fiscal, o branqueamento ou uma associação criminosa. A preocupação com as consequências de uma exploração ilícita de jogos de fortuna ou azar foi reforçada na recente legislação do jogo online em Portugal, pelo que não será de desprezar a situação dos intervenientes neste processo, em que tem um papel essencial o jogador, o qual poderá inclusivamente ser um jogador patológico, mas visa igualmente a proteção dos menores e da família.

  • Pharmacogenetic: screening relevant polymorphisms on antiretroviral therapy in a HIV Portuguese population
    Publication . Fernandes, A.; Cruz, J. P.; Paixão, P.; Valadas, E.; Morais, J. G.; Ribeiro, A. C.
    "Several factors cause heterogeneity of response to antiretroviral therapy. Genetic polymorphisms, particularly in metabolizing enzyme, cytochrome P450 isoenzymes and transport proteins MDR, MRP and SLC, may cause pharmacokinetic variability in some ARVs, leading to viral failure, drug toxicity and may explain the interpatient variability for drug absorption pathways."

  • The Pierre Auger Cosmic Ray Observatory
    Publication . Pierre Auger collaboration (567 authors); Abreu, Pedro; Andringa, Sofia; Assis, Pedro; Brogueira, Pedro; Cazon, Lorenzo; Conceição, Ruben; Diogo, Francisco; Espadanal, Joao; Gonçalves, Patrícia; Oliveira, Micael; Pimenta, Mário; Santo, Catarina E; Santos, Eva; Sarmento, Raul; Tomé, Bernardo
    The Pierre Auger Observatory, located on a vast, high plain in western Argentina, is the world's largest cosmic ray observatory. The objectives of the Observatory are to probe the origin and characteristics of cosmic rays above $10^{17}$ eV and to study the interactions of these, the most energetic particles observed in nature. The Auger design features an array of 1660 water-Cherenkov particle detector stations spread over 3000 km$^2$ overlooked by 24 air fluorescence telescopes. In addition, three high elevation fluorescence telescopes overlook a 23.5 km$^2$, 61-detector infilled array with 750 m spacing. The Observatory has been in successful operation since completion in 2008 and has recorded data from an exposure exceeding 40,000 km$^2$ sr yr. This paper describes the design and performance of the detectors, related subsystems and infrastructure that make up the Auger Observatory.

  • Summary of the ATLAS experiment’s sensitivity to supersymmetry after LHC Run 1 — interpreted in the phenomenological MSSM
    Publication . ATLAS collaboration (2866 authors); Aguilar-Saavedra, Juan Antonio; Amor Dos Santos, Susana Patricia; Anjos, Nuno; Araque, Juan Pedro; Cantrill, Robert; Carvalho, João; Castro, Nuno Filipe; Conde Muiño, Patricia; Da Cunha Sargedas De Sousa, Mario Jose; Fiolhais, Miguel; Galhardo, Bruno; Gomes, Agostinho; Gonçalo, Ricardo; Jorge, Pedro; Lopes, Lourenco; Machado Miguens, Joana; Maio, Amélia; Maneira, José; Onofre, António; Palma, Alberto; Pedro, Rute; Pina, João Antonio; Santos, Helena; Saraiva, João; Silva, José; Tavares Delgado, Ademar; Veloso, Filipe; Wolters, Helmut
    A summary of the constraints from the ATLAS experiment on R-parity-conserving supersymmetry is presented. Results from 22 separate ATLAS searches are considered, each based on analysis of up to 20.3 fb$^{−1}$ of proton-proton collision data at centre-of-mass energies of $ \sqrt{s}=7 $ and 8 TeV at the Large Hadron Collider. The results are interpreted in the context of the 19-parameter phenomenological minimal supersymmetric standard model, in which the lightest supersymmetric particle is a neutralino, taking into account constraints from previous precision electroweak and flavour measurements as well as from dark matter related measurements. The results are presented in terms of constraints on supersymmetric particle masses and are compared to limits from simplified models. The impact of ATLAS searches on parameters such as the dark matter relic density, the couplings of the observed Higgs boson, and the degree of electroweak fine-tuning is also shown. Spectra for surviving supersymmetry model points with low fine-tunings are presented.
