A Universidade Portuguesa: o abrir do fecho de acesso : o caso dos maiores de 2...

Este artigo integra uma dupla preocupação. Por um lado, procedemos a um enquadramento histórico do processo constitutivo da universidade portuguesa. Por outro, quisemos contemplar uma dimensão empírica. Para darmos seguimento às preocupações enunciadas fizemos (i) uma análise documental onde explorámos diferentes tipos de fontes (manuscritas e impressas) e (ii) aplicámos um questionário a uma amostra de 36 alun...

Modeling intra- and inter-team spatial interaction patterns in invasive team sp...

Doutoramento em Motricidade Humana na especialidade de Treino Desportivo ; Team sports games are recognized as dynamic systems of interaction, where individual and collective patterns of behavior emerge from a confluence of multiple organismic, environmental and task-related constraints on the players. Researchers have been interested in studying the dynamic interaction of these many degrees of freedom for at ...

Territorial gain dynamics regulates success in attacking sub-phases of team sports

Background and objective: Field invasion games, such as rugby union, can be conceptualised as dynamic social systems in which the agents continuously interact to contest ball possession and territorial gain. Accordingly, this study aimed to identify the collective system dynamics of rugby union phases-of-play near the try line by investigating whether ball displacement trajectory on the playing field provides i...

Solubilization of Poly1,4-phenylene-[9,9-bis(4-phenoxy-butylsulfonate)] fluoren...

In the presence of the nonionic alkyloxyethylene surfactant n-dodecylpentaoxyethylene glycol ether (C12E5), the anionic conjugated polyelectrolyte (CPE) poly1,4-phenylene-[9,9-bis(4-phenoxy-butylsulfonate)]fluorene-2,7-diyl (PBS-PFP) dissolves in water, leading to a blue shift in fluorescence and dramatic increases in fluorescence quantum yields above the surfactant critical micelle concentration (cmc). No sign...

Synthesis, spectroscopy, photophysics and thermal behaviour of stilbene-based t...

Novel stilbene-based triarylamines with dehydroabietic acid methyl ester moieties have been synthesised by palladium catalysed C–N coupling reactions. The presence of the bulky dehydroabietic acid group increases solubility, hinders crystallisation and permits their sublimation while preserving their electronic and optical characteristics. This makes them good candidates for various molecular electronic applica...
