WOS:000307679500004 (Nº de Acesso Web of Science) ; “Prémio Científico ISCTE-IUL 2013” ; Two factors increase the threat for individuals' belief in a just world (BJW) posed by an innocent victim: the degree of the observer's explicit endorsement of BJW and the fact that the victim shares a common identity with the observer. In this paper, we aim to investigate whether or not these two factors (BJW and ingroup...
Comunicação apresentada na Global Fashion International Conference que ocorreu entre 11 a 13 de Novembro de 2010 no Porto. ; The success of national fashion brands seems to be vital for the competitiveness of the Portuguese Apparel Sector. This sector continues to play an important role for the country. Recent years have assisted to significant changes due to total liberalization of trade of textiles and clot...
The effect of physical exercise on the treatment of depressive elderly adults has not been investigated thus far in terms of changes in cortical hemispheric activity. The objective of the present study was to identify changes in depressive symptoms, quality of life, and cortical asymmetry produced by aerobic activity. Elderly subjects with a diagnosis of major depressive disorder (DSM-IV) were included. Twenty ...
Um método para avaliar a dureza e o rendimento na moagem de matérias-primas para a fabricação de revestimentos cerâmicos por via seca foi o objetivo deste trabalho. A avaliação do potencial de uso de uma dada matéria-prima argilosa para a indústria de revestimentos cerâmicos por via seca não costuma contemplar características como a dureza e o rendimento na moagem, mas estas características afetam a durabilidad...
Posicionar um ponto, uma linha ou uma área nada mais é do que atribuir-lhe coordenadas. Embora hoje se trate de uma tarefa que pode ser realizada com relativa simplicidade, utilizando-se satélites artificiais apropriados para esse fim, este foi no passado um dos primeiros problemas científicos que o ser humano procurou solucionar. O homem sempre esteve interessado em saber onde estava, inicialmente restrita à v...
O gás natural, atualmente, é a principal fonte de geração de energia térmica utilizada pelas indústrias de revestimentos cerâmicos no mundo e também é um dos itens que tem maior participação sobre o custo do produto acabado. Neste trabalho é apresentado um levantamento do consumo de gás natural realizado em uma indústria de via seca do pólo produtivo de Santa Gertrudes - SP, de modo que foi possível determinar ...
We present, our preliminary results of a systematic theoretical study of the adsorption of N over As-terminated GaAs (100) (2×1) surfaces. We analyzed the changes in the bond-lengths, bond-angles and the energetics involved before and after deposition. Our results show that the N-atoms will prefer the unoccupied sites of the surface, close to the As dimer. The presence of N pushes the As dimer out of the ...
In this work, we presented our preliminary ab initio results for the vibrational modes and the phonon frequencies of the SiC (100) surfaces. Our results are in good agreement with the available experimental data whenever this comparison is possible. For the accepted models of the C-terminated surfaces in the c(2×2) reconstruction, while in the bridge-dimer model there is an acetylene-like vibrational A1 m...
In this work, we present our preliminary ab initio results for the structural and electronic properties of both Si- and C-terminated SiC (100) surfaces in (2×1) and c(2×2) reconstruction patterns. Based on our results, we found that the Si-terminated surfaces are dominated by weak bonded Si-dimers, which are stabilized only at Si-rich conditions, leading to (3×2) or more complex reconstruction...
We have calculated the vibrational modes and frequencies of the crystalline PPP (in both the Pbam and Pnnm symmetries) and PPV (in the P2(1)/c symmetry). Our results are in good agreement with the available experimental data. Also, we have calculated the temperature dependence of their specific heats at constant volume, and of their vibrational entropies. Based on our results, at high temperatures, the PPP is m...
