Survey of the Floating Photovoltaic Potential of Portugal

Portugal is characterized by a high solar potential with annual global horizontal solar irradiation exceeding 1800 kWh/m2 [1]. Due to this radiation availability and the sharp reduction in costs that has occurred in the last decade, solar photovoltaic has shown a market growth and an increasing penetration in the Portuguese national electricity generation system. The application of floating photovoltaic (FPV) technology brings the advantage of using an otherwise potentially unused area and can present a yield increase due to its installation over water, at the same time providing a reduction in water evaporation [2]. This study provides a comprehensive analysis of the potential for FPV installation in mainland Portugal, using water body data by the Portuguese Environment Agency (APA). This analysis results in a mapping of the potential areas for FPV applications in the national territory, thus establishing a relationship between the availability of solar radiation and the geographical distribution of water bodies in the different regions of the country. This work intends to determine if the FPV potential in Portugal can contribute to the installed capacity target as defined in the Portuguese National Energy and Climate Plan 2030 (PNEC 2030), which defines the goal of 7GW of solar photovoltaic systems in 2030 [3]

Rinometria acústica, rinomanometria computadorizada e espirometria de doentes asmáticos com sintomas de rinite pré e pós-curso de corticóide oral

Resumo: Introdução: Asma e rinite frequentemente coexistem no mesmo paciente. Parece existir uma condição que afecta o tracto respiratório como um todo e que pode produzir sintomas na via aérea inferior e/ou superior.Objetivo: Estudar as alterações funcionais das vias aéreas inferiores e superiores em pacientes em crise de asma antes e pós-curso de corticóide oral.Métodos: No período de Julho de 2000 a Agosto de 2002, dezasseis pacientes (69% do sexo feminino) em crise de asma com sintomas de rinite atendidos no pronto atendimento de pneumologia foram analisados por meio de um ensaio clínico observacional porquestionário de sintomas, exame físico, radiograma, espirometria, rinometria acústica e rinomanometria computadorizada.Resultados: Dezasseis pacientes apresentaram sintomas de comprometimento das vias aéreas superiores. Na espirometria, o VEF1, o VEF1 /CVF e o FEF25-75%, apresentaram diferenças estatísticas significativas. A rinometria acústica apresentou diferença estatística significativa na área variável transversal mínima 1 e 2 do lado esquerdo e volume total nasal, pós-intervenção medicamentosa.Conclusões: Nas avaliações funcionais de vias aéreas inferiores e superiores, foram observadas melhora do VEF1, VEF1 /CVF e FEF, medidos pela espirometria e do volume total nasal, analisado pela 25-75% rinometria acústica pós-intervenção de corticóide oral.Rev Port Pneumol 2005; XI (1): 35-46 Abstract: Introduction: Asthma and rhinitis frequently coexist in the same patient. It may exist a specific condition witch affects the general respiratory activity and also able to produce symptoms into upper and/ or lower airways.Purpose: To analyze the alteration and functional burst of upper and lower airways before and after oral corticoid.Methods: From July of 2000 to August of 2002, sixteen (69 % was female), acute asthmatics patients with rhinitis symptom assisted in the pneumology department, were analyzed through cross-sectional study using: symptoms questionnaire, physical examination, radiogram, spirometry, acoustic rhinometry, and rhinomanometry.Results: Sixteen patients presented compromising symptoms of the upper airways. In the spirometry, FEV1, FEV1 /FVC e FEF, presented major statistically differences. The acoustic rhinometry 25-75% presented important statistical differences in the minimal cross- sectional area 1 e 2 in the left side and total nasal volume, after medicine intervention.Conclusions: The functional evaluations upon lower and upper airways, improvements in FEV1, FEV1 / FVC e FEF, were observed through spirometry 25-75% and total nasal volume, analyzing the acoustic rhinometry after oral corticoid.Rev Port Pneumol 2005; XI (1): 35-46 Palavras-chave: Asma, rinite, rinometria, aústica, rinomanometria computadorizada, espirometria, Key-words: Asthma, rhinitis, acoustic rhinometry, rhinomanometry, spirometr
