McCabe v Goliath: The case against British American tobacco Australia Services Ltd

Significance of the decision in McCabe v British American Tobacco Australia Services Ltd - ramifications for the possibilities for success of future litigation of this nature in Australia and overseas - ethical and public policy issues regarding the duties of lawyers to the courts and to their clients - whilst a lawyer's implication in the destruction of documents to prevent a fair trial ultimately involves stricter duties, it exposes a need for vigilance against the possibilities for corporations to act outside the public interest, if not the justice system.

Desenfumagem em edifícios: parque de estacionamento coberto (retail - Oeiras parque)

Os parques de estacionamento surgiram da necessidade de disponibilização de espaço de parqueamento de veículos que fazem parte do quotidiano do Homem, no entanto devido ao facto de poderem ser confinados ou subterrâneos requerem a instalação de ventilação forçada (ventiladores axiais e ventiladores de impulso). Este trabalho tem como objectivo a análise, utilizando métodos de simulação numérica da ventilação forçada criada pelos ventiladores de impulso e pelos ventiladores axiais instalados num parque de estacionamento subterrâneo. Vão ser comparadas várias simulações com situações diferentes em termos de condições de fronteira, obstruções ao escoamento, etc., por forma a tirar conclusões sobre o comportamento do parque numa situação de emergência, ou seja, num incêndio. Este comportamento vai ter em conta a eficiência de evacuação dos gases libertados, as temperaturas no parque que permitem verificar onde estão localizados os gases mais quentes e os campos de velocidade do ar que permitem uma visualização do escoamento e até certo ponto a turbulência do mesmo. No final pretende-se concluir por meio de comparação com outros documentos consultados, a “confiabilidade” do software usado (FDS-Fire Dynamics Simulator) e adicionalmente tirar conclusões sobre o projecto do parque, nomeadamente sobre a necessidade de introdução de alterações.

The 27th British liquid crystal society annual meeting 2013, Cambridge

Attending the British Liquid Crystal Society’s (BLCS) Annual Meeting was a formative experience in my days as a PhD student, starting way back in the 1990s. At that time, this involved travelling to (to me) exotic parts of the United Kingdom, such as Reading, Oxford or Manchester, away from Southampton where I was based. Some postdoctoral years in a different country followed, and three BLCS Meetings were missed, until in 1997 and 1998, I was able to attend again, in Southampton and Leeds, respectively. Not much had changed from my student days, the size and the format were still about the same, many of the leading characters were still around, and the closing talk would still be given by John Lydon. Well, at some point, I got myself a proper academic job on the Continent and stopped attending BLCS Annual Meetings altogether. The fond memories of my youth started to fade. Were the Meetings still on? It seemed so, as old friends and acquaintances would occasionally recount attending them, and even winning prizes at them. But, it all seemed rather remote now. Until, that is, it came to pass that the 27th BLCS Meeting would be held in Selwyn College, Cambridge, just down (or up, depending on how you look at it) the road from the Isaac Newton Institute, where I was spending part of my sabbatical leave. The opportunity to resume attendance could not be missed. A brief e-mail exchange with the organisers, and a cheque to cover the fee, duly secured this. And thus, it was with trepidation that I approached my first BLCS Annual Meeting in more than a decade.

Survey of trace elements (Al, As, Cd, Cr, Co, Hg, Mn, Ni, Pb, Se, and Si) in retail samples of flavoured and bottled waters

Concentrations of eleven trace elements (Al, As, Cd, Cr, Co, Hg, Mn, Ni, Pb, Se, and Si) were measured in 39 (natural and flavoured) water samples. Determinations were performed using graphite furnace electrothermetry for almost all elements (Al, As, Cd, Cr, Co, Mn, Ni, Pb, and Si). For Se determination hydride generation was used, and cold vapour generation for Hg. These techniques were coupled to atomic absorption spectrophotometry. The trace element content of still or sparkling natural waters changed from brand to brand. Significant differences between natural still and natural sparkling waters (p<0.001) were only apparent for Mn. The Mann–Whitney U-test was used to search for significant differences between flavoured and natural waters. The concentration of each element was compared with the presence of flavours, preservatives, acidifying agents, fruit juice and/or sweeteners, according to the labelled composition. It was shown that flavoured waters generally increase the trace element content. The addition of preservatives and acidifying regulators had a significant influence on Mn, Co, As and Si contents (p<0.05). Fruit juice can also be correlated to the increase of Co and As. Sweeteners did not provide any significant difference in Mn, Co, Se and Si content.
