Doutoramento em Gestão ; Although somewhat outdated, the American Marketing Association definition of brand still is largely accepted. In this case, brands are signs for product differentiation. The present research, instead, finds brands and their logos as meaningful signs that belong to the human communicative lexicon. Logos are ideograms, i.e. graphic representations that convey meanings. These meanings are...
The most important processes for the creation of S12+ to S14+ ions excited states from the ground configurations of S9+ to S14+ ions in an electron cyclotron resonance ion source, leading to the emission of K X-ray lines, are studied. Theoretical values for inner-shell excitation and ionization cross sections, including double KL and triple KLL ionization, transition probabilities and energies for the deexcitat...
Este artigo refere uma experiência em curso no ensino superior que está a usar uma metodologia de projecto e uma estratégia de tipo b-learning com recurso a ferramentas da Web 2.0, nomeadamente a Projectic, construída com base no NING, serviço que permite criar redes sociais. A criação deste ambiente virtual tem como finalidade construir um espaço de partilha de recursos sobre a metodologia de trabalho de proje...
In this paper we review the different relativistic and QED contributions to energies, ionic radii, transition probabilities and Landé g-factors in super-heavy elements, with the help of the MultiConfiguration Dirac-Fock method (MCDF). The effects of taking into account the Breit interaction to all orders by including it in the self-consistent field process are demonstrated. State of the art radiative correction...
