This study determined annual and monthly fluctuations in concentration of 20 fungal genera. The selection of taxa was made based upon their high frequency in the air as well as their well-known allergenic properties. Air samples were collected using a spore trap of Hirst design at an urban site where the trap continuously worked throughout a 5-year survey. Weather data were acquired from a meteorological station co-located with the air sampler. Influence of several meteorological parameters was then examined to reveal species–environment interactions and the potential location of fungal spore sources within the urban area. The maximum monthly sum of mean daily spore concentration varied between genera, and the earliest peaks were recorded for Pleospora sp. in April and Ustilago sp. in June. However, the majority of investigated spore types occurred in the greatest concentrations between August and September. Out of the 20 studied taxa, the most dominant genus was Cladosporium sp., which exceeded an allergenic threshold of 3000 s m-3 40 times during very rainy years and twice as much during dry years. A Spearman’s rank test showed that statistically significant (p B 0.05) relationships between spore concentration and weather parameters were mainly rs B 0.50. Potential sources of spores at Worcester were likely to be localised outside the city area.

G.H. Mead (1863-1931) oriented much of his intellectual efforts around three unavoidable questions for anyone living in a modern society: how are selfhood, knowledge, and politics understood and organized in such a society? Modern individuals continually seek answers to questions although nobody has ever come up with a definitive answer to them. Modernity, in other words, confronts us with inevitable problematics that fundamentally shape the way in which we think about certain topics. For the purposes of my discussion of Mead, I focus upon three of these modern problematics: science, selfhood, and democratic politics. But before I discuss Mead’s treatment of these problem areas, allow me to briefly situate Mead as a pragmatist in relation to Dewey and James within pragmatism.

In 1968, Herbert Marcuse believed that a Great Refusal was possible, one that would deny the exploitative power of corporate capitalism. Marcuse's vision was never realised. This essay argues that society today is in an advanced state of that which the Frankfurt School termed repressive desublimation and questions whether a liberationary praxis is still possible. It claims that Bret Easton Ellis's fiction choreographs an internalising of the forms of critique that marked 1968 and about which Marcuse writes. It is Ellis's act of double voicing that allows him to develop a duplicitous recalcitrant voice within the state of assimilation and it is double voicing which emerges as the key technique in Ellis's work that effects an ongoing critique in commodity society. Looking at Slavoj iek's recent revisionism of the notion of repressive desublimation, which connects Marxism and psychoanalysis, the essay considers how Ellis's novels, American Psycho, Glamorama and Lunar Park, function to address and reconfigure the relationship between the status of the Marxist fetishised object and the psychoanalytic phobic object in the present-day era of late capitalism. This essay seeks to illuminate how Ellis's fiction, through an involution of Marcuse's political theories, enacts a contemporary refusal from within the state of reification.

A new procedure for determining eleven organochlorine pesticides in soils using microwave-assisted extraction (MAE) and headspace solid phase microextraction (HS-SPME) is described. The studied pesticides consisted of mirex, α- and γ-chlordane, p,p’-DDT, heptachlor, heptachlor epoxide isomer A, γ-hexachlorocyclohexane, dieldrin, endrin, aldrine and hexachlorobenzene. The HS-SPME was optimized for the most important parameters such as extraction time, sample volume and temperature. The present analytical procedure requires a reduced volume of organic solvents and avoids the need for extract clean-up steps. For optimized conditions the limits of detection for the method ranged from 0.02 to 3.6 ng/g, intermediate precision ranged from 14 to 36% (as CV%), and the recovery from 8 up to 51%. The proposed methodology can be used in the rapid screening of soil for the presence of the selected pesticides, and was applied to landfill soil samples.

A procedure for the determination of seven indicator PCBs in soils and sediments using microwave-assisted extraction (MAE) and headspace solid-phase microextraction (HS-SPME) prior to GC-MS/MS is described. Optimization of the HS-SPME was carried out for the most important parameters such as extraction time, sample volume and temperature. The adopted methodology has reduced consumption of organic solvents and analysis runtime. Under the optimized conditions, the method detection limit ranged from 0.6 to 1 ng/g when 5 g of sample was extracted, the precision on real samples ranged from 4 to 21% and the recovery from 69 to 104%. The proposed method, which included the analysis of a certified reference material in its validation procedure, can be extended to several other PCBs and used in the monitoring of soil or sediments for the presence of PCBs.

A necessidade de construir que se manifesta em todos os sectores, desde o da habitação, em que o homem recupera da fadiga física e intelectual, consequência da sua actividade diária, até àquele em que exerce a sua actividade de produção ou onde realiza as suas ocupações sociais dos tempos livres, obriga a procurar soluções, para a limitação de espaços - cada vez mais económicos em tempo, dinheiro, materiais e mo de obra. Este objectivo levou ao desenvolvimento de técnicas de pré-fabricação,e bem assim a industrializar a construção, por elementos cada vez maiores - de acordo com os meios mecânicos de que se pode dispor na zona industrial, nos transportes e no estaleiro. Assim, conforme os elementos de construção a colocar em obra são manuseáveis ou, pelas suas dimensões e peso, careçam de meios mecânicos para poderem ser utilizados, a pré fabricação está diferenciada em: a) Pré fabricação ligeira b) Pré fabricação pesada Por outro lado, os diversos materiais que se utilizam na construção permitem a pré fabricação industrial de elementos de construção: metálicos, de madeira, de betão, de pedra, de argila cozida, de vidro, etc.

The integration of wind power in eletricity generation brings new challenges to unit commitment due to the random nature of wind speed. For this particular optimisation problem, wind uncertainty has been handled in practice by means of conservative stochastic scenario-based optimisation models, or through additional operating reserve settings. However, generation companies may have different attitudes towards operating costs, load curtailment, or waste of wind energy, when considering the risk caused by wind power variability. Therefore, alternative and possibly more adequate approaches should be explored. This work is divided in two main parts. Firstly we survey the main formulations presented in the literature for the integration of wind power in the unit commitment problem (UCP) and present an alternative model for the wind-thermal unit commitment. We make use of the utility theory concepts to develop a multi-criteria stochastic model. The objectives considered are the minimisation of costs, load curtailment and waste of wind energy. Those are represented by individual utility functions and aggregated in a single additive utility function. This last function is adequately linearised leading to a mixed-integer linear program (MILP) model that can be tackled by general-purpose solvers in order to find the most preferred solution. In the second part we discuss the integration of pumped-storage hydro (PSH) units in the UCP with large wind penetration. Those units can provide extra flexibility by using wind energy to pump and store water in the form of potential energy that can be generated after during peak load periods. PSH units are added to the first model, yielding a MILP model with wind-hydro-thermal coordination. Results showed that the proposed methodology is able to reflect the risk profiles of decision makers for both models. By including PSH units, the results are significantly improved.

À medida que o mundo Ocidental se apresenta cada vez mais subjugado ao primado da tecnologia (Forman, 2007:1), a possibilidade de ignorar o crescente impacte da Ludologia vai-se gradualmente inviabilizando. Através da adopção de uma perspectiva anglo-portuguesa, a presente dissertação focar-se-á no amplamente popular jogo de vídeo Sid Meier’s Civilization V: Brave New World (2013). Ao (re)interpretar as relações luso-britânicas no espaço de tempo compreendido entre 1890 (Ultimatum britânico) e 1910 (implantação da Primeira República Portuguesa), a presente dissertação tem em vista não só estudar a imprensa periódica portuguesa e inglesa, mas também demonstrar o modo como o jogo de vídeo em questão permite ao jogador desconstruir o “prepotente” domnio britânico sobre o “little Portugal”. Neste contexto, atribuir-se-á um lugar de destaque ao evolucionismo de Herbert Spencer. Profundamente respeitado por toda a Europa, durante a segunda metade do século XIX e princípios do século XX, o pensamento spenceriano revelou-se fundamental para compreender, por um lado, e em toda a sua extensão, o discurso jornalístico de finais do século XIX e inícios do XX, e, por outro, a narrativa e a estética do jogo Sid Meier’s Civilization V: Brave New World. De um modo geral, a presente análise visa, acima de tudo, questionar o cariz pós-colonial do jogo de vídeo sob observação e, simultaneamente, a sua capacidade de desafiar, de forma subversiva, o que pode ser tido como uma arrogante soberania britânica sobre um Portugal militar, económica e politicamente indefeso.

If an opening to the argument of this dissertation is of imperative necessity, one might tentatively begin with Herbert Quain, born in Roscommon, Ireland, author of the novels The God of the Labyrinth (1933) and April March (1936), the short-story collection Statements (1939), and the play The Secret Mirror (undated). To a certain extent, this idiosyncratic Irish author, who hailed from the ancient province of Connacht, may be regarded as a forerunner of the type of novels which will be considered in this dissertation. Quain was, after all, the unconscious creator of one of the first structurally disintegrated novels in the history of western literature, April March. His first novel, The God of the Labyrinth, also exhibits elements which are characteristic of structurally disintegrated fiction, for it provides the reader with two possible solutions to a mysterious crime. As a matter of fact, one might suggest that Quain’s debut novel offers the reader the possibility to ignore the solution to the crime and carry on living his or her readerly life, turning a blind eye to the novel itself. It may hence be argued that Quain’s first novel is in fact a compound of three different novels. It is self-evident that the structure of Quain’s oeuvre is of an experimental nature, combining geometrical precision with authorial innovation, and one finds in it a higher consideration for formal defiance than for the text itself. In other words, the means of expression are the concern of the author and not, interestingly, the textual content. April March, for example, is a novel which regresses back into itself, its first chapter focussing on an evening which is preceded by three possible evenings which, in turn, are each preceded by three other, dissimilar, possible evenings. It is a novel of backward-movement, and it is due to this process of branching regression that April March contains within itself at least nine possible novels. Structure, therefore, paradoxically controls the text, for it allows the text to expand or contract under its formal limitations. In other words, the formal aspects of the novel, usually associated with the restrictive device of a superior design, contribute to a liberation of the novel’s discourse. It is paradoxical only in the sense that the idea of structure necessarily entails the fixation of a narrative skeleton that determines how plot and discourse interact, something which Quain flouts for the purposes of innovation. In this sense, April March’s convoluted structure allows for multiple readings and interpretations of the same text, consciously germinating narratives within itself, producing different texts from a single, unique source. Thus, text and means of expression are bonded by a structural design that, rather than limiting, liberates the text of the novel.
