Seismic imaging of the western Iberian crust using ambient noise: Boundaries and internal structure of the Iberian Massif

We present new Rayleigh-wave dispersion maps of the western Iberian Peninsula for periods between 8 and 30 s, obtained from correlations of seismic ambient noise, following the recent increase in seismic broadband network density in Portugal and Spain. Group velocities have been computed for each station pair using the empirical Green's functions generated by cross-correlating one-day-length seismic ambient-noise records. The resulting high-path density allows us to obtain lateral variations of the group velocities as a function of period in cells of 0.5 degrees x 0.5 degrees with an unprecedented resolution. As a result we were able to address some of the unknowns regarding the lithospheric structure beneath SW Iberia. The dispersion maps allow the imaging of the major structural units, namely the Iberian Massif, and the Lusitanian and Algarve Meso-Cenozoic basins. The Cadiz Gulf/Gibraltar Strait area corresponds to a strong low-velocity anomaly, which can be followed to the largest period inverted, although slightly shifted to the east at longer periods. Within the Iberian Massif, second-order perturbations in the group velocities are consistent with the transitions between tectonic units composing the massif. (C) 2013 Elsevier B.V.

Análise e melhoria de processo de pintura e vulcanização na Continental

A indústria automóvel é um dos setores mais exigentes do mercado global, por este motivo empresas como a Continental Mabor S.A, líderes de mercado, necessitam estar na linha da frente no que toca a programas de melhoria contínua e de uma gestão orientada para um crescimento rentável e sustentado. Nesta perspetiva, este estudo de dissertação tem como objetivo encontrar uma solução para a gestão de stock e FiFo (First in First out) de pneus em verde na supracitada empresa, situada em Lousado, Vila Nova de Famalicão. Este projeto de dissertação iniciou-se com uma análise e diagnóstico do processo produtivo do pneu, entre a Construção e a Vulcanização. Nesta análise, foi possível identificar vários problemas, sendo o mais crítico associado à logística interna de transporte do pneu “em curso”, de fabrico entre as fases do mesmo, Construção e Vulcanização. Devido a condicionantes estruturais e de organização, a logística interna de transporte entre estes dois sectores enfrenta estrangulamentos nos fluxos, a falta de espaço para acomodar o material em curso, problemas organizacionais de controlo e monitorização do processo produtivo, dificuldades de regulação do fluxo e localização dos carros de transporte dos pneus em verde. Face aos problemas detetados ao longo do estudo, foram analisadas várias soluções para a resolução ou minimização dos mesmos. Entre as soluções propostas salientam-se: o alargamento do sistema de transporte por tapetes rolantes GTC (Green Tire Conveying) a todos os módulos de construção. Esta solução diminui o fluxo de carros para a área da construção, descongestionando a zona próxima do sistema de carregamento automático GTAL (Green Tire Automatic Loading) na vulcanização. A implementação dum sistema Wi-Fi RFID, que permite identificar e localizar artigos em curso utilizando etiquetas inteligentes numa rede wireless, conseguindo melhorar a programação de produção e o respetivo sequenciamento. Sabendo também que a Continental se encontra numa fase de expansão, designada Projeto Route 17/20, as soluções propostas tomaram em consideração essa nova realidade futura. Assim, foram estudados e propostos novos layouts para esse atual processo. Nestes novos layouts, procurou-se uma reorganização dos processos de fabrico, bem como um redimensionamento dos espaços de parqueamento de carros de pneus verdes adequado aos volumes produtivos. De igual forma, adequou-se os espaços físicos à possível implementação de um sistema de FiFo de pneus em verde na planta fabril, quando concluída a expansão. Este trabalho de dissertação apresenta como vantagens diretas da sua implementação: gerar a menor perturbação no atual método de trabalho seguido na empresa; previsivelmente aumentar a eficiência do processo produtivo; potenciar o crescimento tecnológico programado pela empresa; e oferecer uma boa relação custo/benefício no investimento necessário. Como apreciação final, pode-se concluir que este estudo foi finalizado com sucesso, visto que as soluções propostas foram apreciadas positivamente pela Administração da Continental Mabor S.A. e estão correntemente a ser avaliadas pelo grupo.

Pulmonary tuberculosis in Continental Portugal 2000-2010: temporal trends clustering as a tool for control evaluation

Clustering analysis is a useful tool to detect and monitor disease patterns and, consequently, to contribute for an effective population disease management. Portugal has the highest incidence of tuberculosis in the European Union (in 2012, 21.6 cases per 100.000 inhabitants), although it has been decreasing consistently. Two critical PTB (Pulmonary Tuberculosis) areas, metropolitan Oporto and metropolitan Lisbon regions, were previously identified through spatial and space-time clustering for PTB incidence rate and risk factors. Identifying clusters of temporal trends can further elucidate policy makers about municipalities showing a faster or a slower TB control improvement.

Contributions à la paleontology du Miocène moyen continental du basin du tage

This study on middle Miocene Charophytes from the Tagus'basin indicates the presence of two species. hitherto undescribed from these strata in Portugal, Correlation diagrams of height and width of gyrogonite demonstrate that the populations of Nitellopsis (Tectochara) etrusca from the localities Póvoa de Santarém and Pêro Filho are identical to that from La Grenatière (Hérault, France), The population of Lychnothamnus duplicicarinatus from Tremês is identical to that already known from Anwill (Switzerland). The age of this flora is therefore suggested as being the upper part of the middle Miocene. The results of Charophyte studies are in accordance with stratigraphical conclusions from previously conducted mammalian studies (Antunes and Mein), A table showing the distribution of species in the three portuguese localities is given.

The lignite-clays of Póvoa de Santarém dated as Upper «Vindobonian» (mammalian zone MN6), fielded abundant remains of animals and plants (spores, pollens, seeds, etc.). The forms identified are indicative of several environments. Plants, either aquatic or belonging to swampy areas are predominant (Nuphar sp., Sparganium sp., Stratiotes kaltennordheimensis, cf. Ranunculus sp.). There are also remains of plants characteristiques of a humid rather than a swampy soil such as Polypodiaceae, Myrica ceriferiformis, Toddalia maii, Spirematospermum wetzeleri. The genera Vitis and Ephedra, although rare, point fowards the existence of drier regions in the neighbourhood. The presence of polens such as Picea indicate the presence at some distance less warm upland forest areas.

Sobre alguns problemas do Permo-Carbónico Continental português

1 - The author presents a synopsis about the non-marine Carboniferous formations represented in the sheets 9A (Póvoa de Varzim), 9C (Porto), 13B (Castelo de Paiva) and, still in preparation, 9D (Penafiel) of the 1/50,000 Geological Map of Portugal. 2 - Conclusions of the detailed petrological research conducted on the Douro Coalfield peranthracites and, also, a new geological interpretation, which originates from those investigations, are presented. 3 - It is discussed how the elements reported and 2 necessitate the revision of some concepts stilt prevailing, namely about the Carboniferous of São Felix de Laundos (Póvoa de Varzim), Ervedosa (Valongo), and their lengthenings. 4 - The geological history of the region since the deposition of the Coblenzian until the end of the Paleozoic is sketched.

Contributions à la Paléontologie du Miocène moyen continental du Bassin du Tage. I - Quelques mollusques - Pero Filho, Póvoa de Santarém, Sítio do Mirante

Some land and freshwater mollusks (Gastropoda, Pelecypoda) from three middle Miocene localities: Pêro Filho, Póvoa de Santarém, Sítio do Mirante, all in Ribatejo province, Portugal, are summarily studied. On a systematical viewpoint it has been shown (see also Tableau): - the presence of the genus Janulus, whose species only survive now at Madeira and Canary's islands; - the presence of "Helix" cotteri that may indeed belong in the genus Megalotachea, common in western Europe since "Helvetian" to Messinian times; - Limax, Testacella, Acroloxus and Pseudamnicola are quoted for the first time in portuguese tertiary formations; Ferrisia has been identified for the first time in Iberian Peninsule; - the presence of other forms previously quoted by ANTUNES & ZBYSZEWSKI (1973), is confirmed: Bithynia, Theodoxus, Pisidium. Such faunules are compatible with a middle Miocene age. On a paleobiogeographical viewpoint, some forms suggest mediterranean affinities. Fossil associations do correspond ecologically to either palustrine or stagnant, calm and shallow water conditions (Sítio do Mirante, and essentially also Póvoa de Santarém), or to fluviatile conditions (Pêro Filho).

The study of Cyprinid fish pharyngeal teeth, collected by M. Telles Antunes in continental "Helvetian" sediments from Póvoa de Santarém, makes possible to demonstrate the occurrence of two distinct species. One remains undetermined. The other belongs to the recent genus Leuciscus CUV. Several dental types of this genus are described and figured as Leuciscus antunesi nov. sp. Palaeoclimatical and palaeoecological interpretations are proposed.

This study on middle Miocene mammalian faunas from Tagus'basin deals particularly with some small mammals hitherto undescribed from Portugal, including a new Glirid (Paraglirulus scalabicensis nov. sp.); it allows an accurate datation by biostratigraphical standards, Megacricetodon crusafonti, Fahlbuschia darocensis, Cricetodon jotae being characteristic of mammalian MN6 unit, thus their age is nearly that of Sansan and Manchones (however the presence of Peridyromys hamadryas and Lagopsis verus do suggest, amidst this biozone, a somewhat later age than Sansan's); it contributes with indirect correlation data with marine formations, as underlying oyster-bearing beds most probably are in correspondance to the apogee of the same transgression that deposed near Lisbon ”schlier" facies from VI-a division (Serravalian, Blow's zones 10-13, Globorotalia meyeri zone); the diversity of mammalian assemblages is surely related to an environement with varied biotopes, whose characterisation becomes easier if account is taken of the preceding papers on mollusks (G. Truc) and Cyprinid fishes (J. Gaudant), and also according to some unpublished paleobotanical data (J. Pais). A table with a synthesis of all paleontological data so far known is presented.

Fontes de fósforo total e o estado trófico de albufeiras em Portugal continental

O estudo realizado incidiu sobre 260 albufeiras, identificadas em diferentes fontes de informação e localizadas em Portugal continental. De entre as massas de água identificadas procedeu-se à classificação do estado trófico de 92 albufeiras, todas para as quais se dispõe de dados de qualidade da água para o efeito. Destas, de acordo com o critério de classificação adoptado em Portugal, 60 foram classificadas como eutróficas, em resultado principalmente das concentrações de fósforo total. Após a delimitação das bacias drenantes de 194 albufeiras, foram implementadas metodologias de quantificação de fósforo total afluente a essas massas de água. Com recurso a um modelo de balanço de massas foram simuladas as concentrações de fósforo total em 80 albufeiras, tendo sido considerados adequados os resultados obtidos em 42 albufeiras. Com base nos resultados obtidos concluiu-se que as metodologias de quantificação de fósforo total de origem urbana e de origem difusa são adequadas ao desenvolvimento de estudos de planeamento e de identificação das principais fontes de fósforo total, em águas doces superficiais.

Critical reappraisal of Late Mesozoic-Cenozoic Central and North Atlantic, Caribbean and Mediterranean evolution

(l) The Pacific basin (Pacific area) may be regarded as moving eastwards like a double zip fastener relative to the continents and their respective plates (Pangaea area): opening in the East and closing in the West. This movement is tracked by a continuous mountain belt, the collision ages of which increase westwards. (2) The relative movements between the Pacific area and the Pangaea area in the W-EfE-W direction are generated by tidal forces (principle of hypocycloid gearing), whereby the lower mantle and the Pacific basin or area (Pacific crust = roof of the lower mantle?) rotate somewhat faster eastwards around the Earth's spin axis relative to the upper mantle/crust system with the continents and their respective plates (Pangaea area) (differential rotation). (3) These relative West to East/East to West displacements produce a perpetually existing sequence of distinct styles of opening and closing oeean basins, exemplified by the present East to West arrangement of ocean basins around the globe (Oceanic or Wilson Cycle: Rift/Red Sea style; Atlantic style; Mediterranean/Caribbean style as eastwards propagating tongue of the Pacific basin; Pacific style; Collision/Himalayas style). This sequence of ocean styles, of which the Pacific ocean is a part, moves eastwards with the lower mantle relative to the continents and the upper-mantle/crust of the Pangaea area. (4) Similarly, the collisional mountain belt extending westwards from the equator to the West of the Pacific and representing a chronological sequence of collision zones (sequential collisions) in the wake of the passing of the Pacific basin double zip fastener, may also be described as recording the history of oceans and their continental margins in the form of successive Wilson Cycles. (5) Every 200 to 250 m.y. the Pacific basin double zip fastener, the sequence of ocean styles of the Wilson Cycle and the eastwards growing collisional mountain belt in their wake complete one lap around the Earth. Two East drift lappings of 400 to 500 m.y. produce a two-lap collisional mountain belt spiral around a supercontinent in one hemisphere (North or South Pangaea). The Earth's history is subdivided into alternating North Pangaea growth/South Pangaea breakup eras and South Pangaea growth/North Pangaea breakup eras. Older North and South Pangaeas and their collisional mountain belt spirals may be reconstructed by rotating back the continents and orogenic fragments of a broken spiral (e.g. South Pangaea, Gondwana) to their previous Pangaea growth era orientations. In the resulting collisional mountain belt spiral, pieced together from orogenic segments and fragments, the collision ages have to increase successively towards the West. (6) With its current western margin orientated in a West-East direction North America must have collided during the Late Cretaceous Laramide orogeny with the northern margin of South America (Caribbean Andes) at the equator to the West of the Late Mesozoic Pacific. During post-Laramide times it must have rotated clockwise into its present orientation. The eastern margin of North America has never been attached to the western margin of North Africa but only to the western margin of Europe. (7) Due to migration eastwards of the sequence of ocean styles of the Wilson Cycle, relative to a distinct plate tectonic setting of an ocean, a continent or continental margin, a future or later evolutionary style at the Earth's surface is always depicted in a setting simultaneously developed further to the West and a past or earlier style in a setting simultaneously occurring further to the East. In consequence, ahigh probability exists that up to the Early Tertiary, Greenland (the ArabiaofSouth America?) occupied a plate tectonic setting which is comparable to the current setting of Arabia (the Greenland of Africa?). The Late Cretaceous/Early Tertiary Eureka collision zone (Eureka orogeny) at the northern margin of the Greenland Plate and on some of the Canadian Arctic Islands is comparable with the Middle to Late Tertiary Taurus-Bitlis-Zagros collision zone at the northern margin of the Arabian Plate.
