Sex and romance are part of everyday life and therefore are part of the contemporary tourism experiences. Tourism, such as has been stressed by the literature, consists of a rupture with the everyday life – a liminal space-time which enables liminal behaviours. In these behaviours one can include a greater willingness for romance and sexual relationships. One of the dimensions of the theoretical articulation be...
This study hypothesizes the existence of three groups of sea lamprey Petromyzon marinus L. in Portugal (North/Central group, Tagus group, and Guadiana group), possibly promoted by seabed topography isolation during the oceanic phase of the life cycle. Within this context, our purpose was to analyze the existence of a stock structure on sea lamprey populations sampled in the major Portuguese river basins using b...
The influence of humidity content on the electrical and dielectric properties of a composite made from recycled TetraPak® containers and granulated cork was studied. The material components have been dried before preparation and after the composite was conditioned by keeping the samples in a dry environment (desiccator) or in an oven at high temperature (70oC in air). The differences observed in electrical prop...
A carne de pescado deve corresponder às expectativas do consumidor no que se refere aos atributos de qualidade sanitária, organolética e nutritiva. Os lípidos são constituintes importantes dos alimentos na medida em que influenciam e determinam o aspeto sensorial do alimento, o sabor, o odor, a maciez, a suculência, a aparência e a sensação de saciedade após a refeição. Estes atributos estão especialmente relac...
Dissertação de mest., Sociologia (Mobilidades e Identidades), Faculdade de Economia, Univ. do Algarve, 2012 ; O sexo e o romance fazem parte da vida quotidiana, mas tendem a ser mais proeminentes durante as férias. O turismo também faz parte das necessidades humanas e representa uma ruptura com a rotina do dia-a-dia. A relação entre turismo, sexo e romance tem sido estudada ao longo dos anos, permitindo uma ma...
This study proposes to evaluate the use of heart tissue fatty acid signature and multivariate analysis of fatty acid profile as a possible discriminating tool for sea lamprey P. marinus populations sampled in Portuguese river basins. Local fisherman collected adult sea lampreys in eight Portuguese river basins (Minho, Lima, Cávado, Douro, Vouga, Mondego, Tagus and Guadiana) at the beginning of their spawning mi...
The electrical properties of natural cork, commercial cork agglomerates (for floor and wall covering) and a composite of cork/TetraPak® were studied. The composite was developed at LNEG/Portugal and is made of recycled cork and TetraPak® containers. Measurements of isothermal charge and discharge currents (ICC/IDC) and dielectric relaxation spectroscopy (DRS) were made. The isothermal currents characteristics a...
Neste trabalho experimental procedeu-se à medição da espessura e à caracterização histológica de lesões ateroscleróticas, em suínos de raça Alentejana, procurando-se estabelecer uma relação entre estas e os valores dos parâmetros sanguíneos associados ao desenvolvimento deste processo patológico. As concentrações plasmáticas de triacilgliceróis, fosfolípidos, colesterol total, colesterol livre, LDLc e HDLc fora...
Abstract The ‘‘Outwelling Theory’’ states that salt marshes play a major role in exporting production to adjacent estuarine and coastal ecosystems. However, it has been found that some marshes act as net importers instead of net exporters of organic matter and nutrients. Once we include mangroves and refine the analysis to comprehend bacterioplankton, organic and stable isotope tracers, the picture became, more...
Apesar da relevância biológica e do impacto económico associado à sua exploração comercial, a informação existente acerca dos hábitos alimentares na fase marinha parasitária da lampreia-marinha é muito limitada e poucos estudos têm examinado a organização metabólica desta espécie. A inactividade alimentar associada à migração reprodutora confere algumas garantias de que a composição em ácidos gordos dos lípidos...
