O Planeta Terra tem vindo a ser fustigado pelas alterações climáticas resultado da poluição ambiental provocada pelo Homem. Com o objectivo de minimizar estes efeitos deletérios, os países mais desenvolvidos estabeleceram compromissos relativamente às emissões de gases com efeito de estufa, tendo por base o Protocolo de Kyoto. A iniciativa «Renováveis na Hora» é uma das medidas previstas no plano para a política de energia e alterações climáticas, apresentado em Fevereiro de 2008, pelo Ministério da Economia e da Inovação Português. Actualmente, em Portugal, existe um mercado emergente para a microgeração, que se rege segundo a legislação aplicada recentemente, que estabelece o novo regime jurídico aplicável à produção de energia por intermédio de unidades de microprodução. Esta iniciativa levará à criação de um novo paradigma de exploração e utilização de energia. Deste modo, é fundamental avançar com alguns alertas das condições de exploração. A energia eólica é umas das fontes renováveis em que o rendimento de conversão pode atingir valores interessantes (poderá ser superior a 50%) e em determinadas regiões o seu potencial é bastante bom, nomeadamente em zonas litorais e em zonas montanhosas. Em ambiente urbano é impraticável a instalação de grandes torres eólicas, mas a micro produção baseada em pequenas turbinas eólicas é perfeitamente possível e desejável. O propósito deste trabalho é realizar um estudo de cariz técnico acerca da instalação de um mini parque eólico num edifício urbano, tendo em conta todas as condicionantes (velocidade do vento, obstáculos na zona, altura de montagem, inter-distância entre aerogeradores). Foi realizado um software que irá auxiliar a escolha dos aerogeradores e inversores para o tipo de local onde vai ser instalado o parque eólico.

Foi realizado um estágio no grupo Porto Bay Hotels & Resorts, um grupo hoteleiro da Região Autónoma da Madeira, com a duração de três meses. Apresenta-se assim no presente trabalho uma perspectiva das Relações Públicas no sector do turismo e hotelaria bem como a discussão do porquê do afunilamento desta função de gestão das relações entre as organizações e os seus públicos nas Guest Relations em algumas das unidades hoteleiras em que trabalhámos. O turismo é actualmente um dos principais sectores da economia mundial. A sobrevivência de um destino turístico, unidade hoteleira ou mesmo de um resort, depende em muito da percepção que os seus stakeholders têm da qualidade dos seus serviços. Assim as Relações Públicas, como em outros sectores, assumem um papel de destaque sendo que estas têm a capacidade de trabalhar a relação entre uma organização e os seus stakeholders, gerindo conflitos e expressando uma identidade positiva sobre a mesma e trabalhando a sua reputação e visibilidade. Em suma este trabalho pretende compreender e reflectir sobre as relações públicas no sector do turismo e hotelaria mesmo quando não o são assim entendidas. Defender-se-á uma perspectiva global, integrada e proactiva das Relações Públicas no sector hoteleiro.

Three commonly consumed and commercially valuable fish species (sardine, chub and horse mackerel) were collected from the Northeast and Eastern Central Atlantic Ocean in Portuguese waters during one year. Mercury, cadmium, lead and arsenic amounts were determined in muscles using graphite furnace and cold vapour atomic absorption spectrometry. Maximum mean levels of mercury (0.1715 ± 0.0857 mg/kg, ww) and arsenic (1.139 ± 0.350 mg/kg, ww) were detected in horse mackerel. The higher mean amounts of cadmium (0.0084 ± 0.0036 mg/kg, ww) and lead (0.0379 ± 0.0303 mg/kg, ww) were determined in chub mackerel and in sardine, respectively. Intra- and inter-specific variability of metals bioaccumulation was statistically assessed and species and length revealed to be the major influencing biometric factors, in particular for mercury and arsenic. Muscles present metal concentrations below the tolerable limits considered by European Commission Regulation and Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO). However, estimation of non-carcinogenic and carcinogenic health risks by the target hazard quotient and target carcinogenic risk, established by the US Environmental Protection Agency, suggests that these species must be eaten in moderation due to possible hazard and carcinogenic risks derived from arsenic (in all analyzed species) and mercury ingestion (in horse and chub mackerel species).

The importance of the organizational relationship (senior managers) with an internal public (employees) is the main focus of this research, aiming to understand how this relationship differs between the different publics. Nowadays, the relevance attributed by Public Relations to this relationship is crucial. The main purpose is to identify two consistent models to measure the impact of an organizational relationship on the internal public. The second purpose is to identify how the internal public react to this organizational relationship, namely by gender. The research was conducted in nine Portuguese companies with a sample of 1.244 subjects in order to study the context of the relationship and validate the identified models. The results show the gender stereotypes in the relationship in these companies and that the organizational relationship has an impact on organizational commitment with a consistent model that highlights the impact of Public Relations on a company's productivity.

A criação artística há muito que evoluí a par com desenvolvimento tecnológico. As novas tecnologias e as novas ferramentas que lhes estão associadas têm possibilitado não só novos meios de expressão, como também contribuído para uma alteração do próprio processo criativo. Desde a câmara obscura utilizada por Canaletto às imagens algorítmicas de George Legrady, muitos são os exemplos da influência das novas tecnologias na expressão e evolução da criação artística. Porém, a esta evolução estão também associadas transformações nos processos de trabalho, e no modo de colaboração entre as várias áreas de saber e suas diferentes especialidades. Os processos condicionam os resultados e no caso concreto do campo artístico representam importantes fatores potenciadores ou condicionadores da interdisciplinaridade e da transdisciplinaridade. Se, por um lado, as tecnologias digitais potenciam uma maior colaboração entre profissionais, por outro poderão ser responsáveis por uma maior fragmentação e hiperespecialização das diferentes fases do processo criativo. As plataformas de convergência, através da standartização de linguagens e ferramentas, induzem a criação artística para uma uniformização dos processos e para uma consequente uniformização dos resultados. A presente comunicação propõe uma reflexão, através da análise de diferentes estudos de caso, sobre a influência dos processos criativos e diferentes metodologias de projeto das artes audiovisuais na inter e transdisciplinaridade.

In previous works we have proposed a hybrid wired/wireless PROFIBUS solution where the interconnection between the heterogeneous media was accomplished through bridge-like devices with wireless stations being able to move between different wireless cells. Additionally, we had also proposed a worst-case timing analysis assuming that stations were stationary. In this paper we advance these previous works by proposing a worst-case timing analysis for the system’s message streams considering the effect of inter-cell mobility.

Recently, there have been a few research efforts towards extending the capabilities of fieldbus networks to encompass wireless support. In previous works we have proposed a hybrid wired/wireless PROFIBUS network solution where the interconnection between the heterogeneous communication media was accomplished through bridge-like interconnecting devices. The resulting networking architecture embraced a Multiple Logical Ring (MLR) approach, thus with multiple independent tokens, where the communication between different domains was supported by the Inter-Domain Protocol (IDP). The proposed architecture also supports mobility of stations between different wireless cells. To that hybrid wired/wireless networking architecture we have proposed a worst-case response timing analysis of the IDP, without considering inter-cell mobility (or handoff) of stations. In this paper, we advance that previous work by proposing a worst-case timing analysis of the mobility procedure.

The marriage of emerging information technologies with control technologies is a major driving force that, in the context of the factory-floor, is creating an enormous eagerness for extending the capabilities of currently available fieldbus networks to cover functionalities not considered up to a recent past. Providing wireless capabilities to such type of communication networks is a big share of that effort. The RFieldbus European project is just one example, where PROFIBUS was provided with suitable extensions for implementing hybrid wired/wireless communication systems. In RFieldbus, interoperability between wired and wireless components is achieved by the use specific intermediate networking systems operating as repeaters, thus creating a single logical ring (SLR) network. The main advantage of the SLR approach is that the effort for protocol extensions is not significant. However, a multiple logical ring (MLR) approach provides traffic and error isolation between different network segments. This concept was introduced in, where an approach for a bridge-based architecture was briefly outlined. This paper will focus on the details of the inter-Domain Protocol (IDP), which is responsible for handling transactions between different network domains (wired or wireless) running the PROFIBUS protocol.

Future industrial control/multimedia applications will increasingly impose or benefit from wireless and mobile communications. Therefore, there is an enormous eagerness for extending currently available industrial communications networks with wireless and mobility capabilities. The RFieldbus European project is just one example, where a PROFIBUS-based hybrid (wired/wireless) architecture was specified and implemented. In the RFieldbus architecture, interoperability between wired and wireless components is achieved by the use specific intermediate networking systems operating at the physical layer level, i.e. operating as repeaters. Instead, in this paper we will focus on a bridge-based approach, which presents several advantages. This concept was introduced in (Ferreira, et al., 2002), where a bridge-based approach was briefly outlined. Then, a specific Inter-Domain Protocol (IDP) was proposed to handle the Inter-Domain transactions in such a bridge-based approach (Ferreira, et al., 2003a). The major contribution of this paper is in extending these previous works by describing the protocol extensions to support inter-cell mobility in such a bridge-based hybrid wired/wireless PROFIBUS networks.

The evolution of the Portuguese Acanthopleuroceratinae is similar to the celto-souabe succession such as it was described in the collects of the Cottards (Cher, France). A subspecies of one of the oldest Acanthopleuroceras (A. carinatum atlanticum) is abundant in the lower part of the Portuguese Ibex zone; this form is described here. The species is recognized in France by several nuclei associated with A. arietiforme (Cottards-22). Generally the similarity between the successive French and Portuguese populations (A. maugenesti, A. valdani, A. alisiense, junior synonym of A. lepidum TUTCHER and TRUEMAN, 1925), is very good. This fact suggests their specific identity. It is typical for A. lepidum of which the greatest populations allow the biometric comparaisons. In Portugal, the mesogean Tropidaceras are missing. This absence of the subboreal Acanthopleuroceras ancestors suggests the straight celto-souabe derivation of the Portuguese Acanthopleuroceras and not a similar local evolution. A. lepidum the last Acanthopleuroceras reaches the western coast of Canada (British Columbia) probably by the Arctic ocean.

Most current-generation Wireless Sensor Network (WSN) nodes are equipped with multiple sensors of various types, and therefore support for multi-tasking and multiple concurrent applications is becoming increasingly common. This trend has been fostering the design of WSNs allowing several concurrent users to deploy applications with dissimilar requirements. In this paper, we extend the advantages of a holistic programming scheme by designing a novel compiler-assisted scheduling approach (called REIS) able to identify and eliminate redundancies across applications. To achieve this useful high-level optimization, we model each user application as a linear sequence of executable instructions. We show how well-known string-matching algorithms such as the Longest Common Subsequence (LCS) and the Shortest Common Super-sequence (SCS) can be used to produce an optimal merged monolithic sequence of the deployed applications that takes into account embedded scheduling information. We show that our approach can help in achieving about 60% average energy savings in processor usage compared to the normal execution of concurrent applications.
