Levantamento diferencial evidenciado pelas escadarias de terraços marinhos do Cabo Espichel e do Cabo Raso durante o Plistocénico

This study focuses on two marine terrace staircases of central Portugal: Cabo Raso (west of Lisboa) and Cabo Espichel (western Arrábida chain). Four emerse marine terraces were found in the Cabo Raso area, while twelve were found at Cabo Espichel, according to geomorphological and stratigraphical studies. Electron Spin Resonance and luminescence dating were used to establish a chronology for the coastal staircases, from which uplift rates were calculated. The present elevations of the culminating marine abrasion platform represented at Cabo Raso and Cabo Espichel, express the differential uplift between these areas over the last ~3,7 Ma

A Avifauna Plistocénica de Portugal: especificidades evolutivas, anatómicas e o seu contexto paleontológico, geológico e arqueológico

[ES]El estudio de los restos de las aves del Pleistoceno juega un papel importante en la comprensión de la paleoecología, porque algunas especies de aves viven en entornos específicos y puede permitir de este modo una mejor comprensión el ambiente en que vivían las comunidades humanas del Paleolítico, objetivo que se pretende en este estudio. Algunos de los sitios arqueológicos del Paleolítico en Portugal son ricos en restos óseos de vertebrados. El estudio da testimonio de la fauna, original se ha centrado principalmente en los mamíferos, en especialmente los mamíferos grandes a expensas de otros grupos de vertebrados, como las aves, la herpetofauna y los peces. Esta tesis tiene entre sus objetivos principales explorar la avifauna fósil de Portugal y contribuir en el conocimiento de estas aves, a partir de vestigios antiguos hasta vestigios del Pleistoceno, que conforman el tema central de esta tesis.[EN]The study of Pleistocene birds remains plays an important role on the understanding of palaeoecology, once different birds lived on specifically distinct environments, leading thus to a better perspective of the environment where the human communities from the Palaeolithic lived. The characterization of that environment it is one of the objectives of this study. Some archaeological sites of the Portuguese Palaeolithic are rich in bones of vertebrates. The study of this palaeofauna has mainly focused on mammals, particularly on great mammals, in determent of other vertebrate groups, such as birds, reptiles and fishes. These theses find its main goal the research of Portuguese fossil avifauna and thus contribute to the knowledge of these birds from the oldest vestiges to the Pleistocene ones, who end up being the central focus of this thesis

Pleistocene Birds of Gruta da Furninha (Peniche-Portugal): A Paleontological and Paleoenvironmental Aproach

This paper reports the practicability of using coffee residues to remove widely used basic dyes like MB (Methylene Blue) from wastewaters. The effect of different batch system parameters, namely stirring speed, pH, initial dye concentration and contact time were studied. Moreover, in continuous fixed-bed column systems, the effects of parameters such as bed-depth, flow rate and initial dye concentration were examined. The experimental batch systems data were simulated using (a) Freundlich, Langmuir and Sips isotherm models and (b) 1st order, 2nd order, and intra-particle kinetic models. The results revealed that the MB is fairly adsorbed on coffee residues. This process could be a low cost technique for the removal of basic dyes from aqueous systems
