Reabilitação de estruturas edificadas: Casa Sommer, Cascais

Esta pesquisa tem como objetivo o desenvolvimento de um modelo de avaliação e diagnóstico das causas das patologias, num processo de remodelação de um edifício do princípio do século XX e ainda no estudo das possíveis medidas corretivas, numa fase primária de avaliação. Neste tipo de intervenção será sempre necessário recorrer às tecnologias atuais e à compreensão da tectónica original, a fim de se poder optimi...

Effect of syngas composition on hydrogen permeation through a Pd–Ag membrane

Hydrogen separation from a syngas mixture with different compositions was studied by using a Pd–Ag membrane. The effect of temperature (from 300 C to 600 C) and of relative pressure (from 0.2 MPa to 0.5 MPa) was studied. In general, rises of both these parameters allowed increasing H2 permeate flux. The Pd–Ag membrane showed to have a great selectivity, as when inlet gas mixture contained different compositio...

Recursos turísticos no concelho do Bombarral : identificação e potencial

Dissertação de Mestrado em Marketing e Promoção Turística apresentada à ESTM - Escola Superior de Turismo e Tecnologia do Mar do Instituto Politécnico de Leiria ; Vivendo no presente um mundo cada vez mais global, em que as distâncias entre países está cada vez mais curta, um destino turístico não está em competição apenas com os que lhe estão mais próximos, sendo uma competitividade a nível planetária. Um dos...

Gasification study of cynara cardunculus to produce hydrogen rich gas

The need to substitute fossil fuel feedstocks with endogeneous biomass to produce energy with lower environmental impact makes necessary to develop innovative and technologically more advanced processes for energy production. Gasification of Cynara cardunculus L. (cardoon) alone and mixed with Eucalyptus was carried out in a bench scale fluidized bed gasifier to study the influence of operating parameters that ...

Fluidised bed combustion of two species of energy crops

The use of biomass fuels for energy production through combustion has a growing application worldwide mainly for two reasons: first, the utilization of biomass for energy contributes to mitigate emission of green house gases; second, its use decreases the dependence of imported fossil fuels in Europe. The objective of this work was to study the combustion behaviour of two endogenous biomass species: cardoon (cy...

Diffuse alveolar hemorrhage resulting from Pauci-immune pulmonary capillaritis

A 27 year-old female patient, cocaine user, presenting hemoptysis and progressive dyspnea with onset 48 hours prior to hospital admission, without any other signs or symptoms. Serum tests for infectious diseases, collagen disorders and vasculitis were negative. Urinalysis was normal. Computed tomography of the chest showed diffuse alveolar infiltrate, affecting mainly the lower left lobe. A thoracoscopic lung b...

Experimental analysis of pressure drop and flow redistribution in axial flows i...

Fuel elements of PWR type nuclear reactors consist of rod bundles, arranged in a square array, and held by spacer grids. The coolant flows, mainly, axially along the rods. Although such elements are laterally open, experiments are performed in closed type test sections, originating the appearance of subchannels with different geometries. In the present work, utilizing a test section of two bundles of 4x4 pins e...
