Use of dialkyldithiocarbamato complexes of bismuth(III) for the preparation of nano- and microsized Bi2S3 particles and the X-ray crystal structures of [Bi{S2CN(CH3)(C6H13)}(3)] and [Bi{S2CN(CH3)(C6H13)}(3)(C12H8N2)]

A range of bismuth(III) dithiocarbamato complexes were prepared and characterized. The X-ray crystal structures of the compounds [Bi{S2CN(CH3)(C6H13)}3] (1) and [Bi{S2CN(CH3)- (C6H13)}3(C12H8N2)] (2) are reported. The preparation of Bi2S3 particulates using a wet chemical method and involving the thermalysis of Bi(III) dialkyldithiocarbamato complexes is described. The influence of several experimental parameters on the optical and morphological properties of the Bi2S3 powders was investigated. Nanosized Bi2S3 colloids were obtained having long-term stability and showing a blue shift on the optical band edge; the presence of particles exhibiting quantum size effects is discussed. Morphological welldefined Bi2S3 particles were obtained in which the fiber-type morphology is prevalent.FCT - POCTI/1999/CTM/ 3545

Representações sociais e expressão tipográfica : criação de logótipos para empresas de calçado

O presente artigo tem como foco a relação entre representações sociais e expressão tipográfica na construção de marcas compostas apenas por logotipo. Seu objetivo norteador é conhecer os processos simbólicos que ocorrem na interação do público com as marcas, a fim de, a partir da análise de logotipos, do ponto de vista do leitor, identificar as conotações legíveis nas características formais da tipografia que os compõe, e então criar efetivamente uma marca para empresa de calçados que tem como público-alvo as classes B e C.ABSTRACT: This Article focuses on the relationship between the social representations and the typographic expression in building brands without symbol. The guiding objective is to know the symbolic process that occurs on the public interaction with the brands in order to create a footwear brand whose audience -target are classes B and C. For it, logos will be analyzed, from the point of view of the reader, to identify the legible connotation in the formal characteristics of the typography that compose brands.info:eu-repo/semantics/publishedVersio

Participation and Institutionalization: Perspectives in urban policies

The democratic crisis expressed by high electoral abstention, distrust in political system and rise of authoritarianism signals the importance of bringing citizens back to the political debate (Fung, 2015). Several authors argue that the renovation of democracy will take place around the political debate about cities, while undergoing intense transformations (Falanga, 2020). It is urgent to rethink participation in urban policies and the evolution of planning instruments and methodologies, helping to confront the decision making with the realityof socio-economic inequalities and environmental imbalances that accompany urban development. Although the urban political discourse contemplates participation, the existing instruments prove to be ineffective and expose known problems. Literature indicates that the effectiveness of participation arises from the interactive dynamics between institutional design - referring to norms and procedures that determine in what, who, how and when one participates, to contextual elements - which include social capital, political will, management implementation capacity and governance issues (Avritzer, 2008; Smith, 2009).info:eu-repo/semantics/publishedVersio

Dynamic critical behaviour in Ising spin glasses

The critical dynamics of Ising spin glasses with Bimodal, Gaussian, and Laplacian interaction distributions are studied numerically in dimensions 3 and 4. The data demonstrate that in both dimensions the critical dynamic exponent $z_{\rm c}$, the non-equilibrium autocorrelation decay exponent $\lambda_c/z_{\rm c}$, and the critical fluctuation-dissipation ratio $X_{\infty}$ all vary strongly and systematically with the form of the interaction distribution.Comment: 8 pages, 4 figures, version to appear in Phys.

Spin and Charge Josephson effects between non-uniform superconductors with coexisting helimagnetic order

We consider the spin and charge Josephson current between two non-uniform Fulde-Ferrel-Larkin-Ovchinnikov superconductors with helimagnetic order. We demonstrate that the presence of the helimagnetic phase generates a spin Josephson effect and leads to additional contributions to both single-particle and Josephson charge current. It is shown that for such systems the AC effect differs more radically from the DC effect than in the case of a BCS superconductor with helimagnetic order considered earlier in the literature [M. L. Kuli\'c and I. M. Kuli\'c, Phys. Rev. B {\bf 63}, 104503 (2001)] where a spin Josephson current has also been found. In our system the most interesting effect occurs in the presence of an external magnetic field and in absence of voltage, where we show that the charge Josephson current can be tuned to zero while the spin Josephson current is non-vanishing. This provides a well controlled mechanism to generate a spin supercurrent in absence of charge currents.Comment: final versio
