Multiyear Measurements of the Aerosol Absorption Coefficient Near the Surface i...

Measurements of the aerosol absorption coefficient, between 2007 and 2013, were made at the ground level in Évora, a Portuguese small town located in the southwestern Iberia Peninsula. Such a relatively long time series of absorbing aerosols is unique in Portugal and uncommon elsewhere.The average aerosol absorption coefficientwas close to 9Mm−1 and clear cycles at both daily and seasonal time scales were found...

Forest Fire Smoke Layers Observed in the Free Troposphere over Portugal with a ...

Vertically resolved optical and microphysical properties of biomass burning aerosols, measured in 2011 with a multiwavelength Raman lidar, are presented.Thetransportation time, within 1-2 days (or less), pointed towards the presence of relatively fresh smoke particles over the site. Some strong layers aloftwere observedwith particle backscatter and extinction coefficients (at 355 nm) greater than 5Mm−1 sr−1 and...

Educational policies and the quality of teaching : perceptions of Portuguese te...

The educational and curricular policies of the last two decades reflect attention to the quality of teaching by associating it with educational success, the improvement of student learning and the professional development of teachers. In this article we present some of the results of an investigation carried out with Portuguese teachers from the first cycle of basic education, who had, as their main objective, ...

The construction of professional knowledge : a comparative study of Social Assi...

This work is centred on the dynamics of identity and professional development of two socio-professional groups; namely, Social Assistants and Mediators. It takes as its point of departure the characterisation of these socio-professional groups and their professionalization. The professionalization of the social groups matches the dynamics of identity development and presupposes social recognition of their profe...

Ties between Portugal and Brazil: A contribution from dental morphology

O Brasil foi descoberto pelos Portugueses, que introduziram Europeus e Africanos em territórios previamente ocupados unicamente por Ameríndios. Caracteres não-métricos dentários foram usados para testar afinidades biológicas entre Brasileiros e Portugueses, para exemplificar a utilidade desta abordagem na interpretação da história das populações humanas. A morfologia dentária, maioritariamente determinada genet...

A relevância do controlo de gestão em empresas de sucesso: estudo de caso Delta...

Dissertação de Mestrado em Ciências Empresariais ; A globalização, em resultado do progresso tecnológico, conducente a uma maior velocidade na circulação da informação, bem como a melhoria dos meios de transporte, permitindo maior proximidade entre os territórios, implicam uma maior criatividade na gestão dos negócios, uma maior capacidade de inovação e um espírito mais empreendedor, dado que os clientes se to...

In search of homelands: using strontium isotopes to identify biological markers...

This study uses strontium isotopes (87Sr/86Sr) in dental enamel from burial populations related to the fortified Chalcolithic settlement site of Zambujal (c. 2800–1800 BC) to distinguish the presence of non-local individuals. Zambujal is located in the Estremadura region of Portugal near the Atlantic coast and has long been considered a central location of population aggregation, craft production, and trade dur...

Mitochondrial complex I dysfunction induced by cocaine and cocaine plus morphin...

Mitochondrial function and energy metabolism are affected in brains of human cocaine abusers. Cocaine is known to induce mitochondrial dysfunction in cardiac and hepatic tissues, but its effects on brain bioenergetics are less documented. Furthermore, the combination of cocaine and opioids (speedball) was also shown to induce mitochondrial dysfunction. In this work, we compared the effects of cocaine and/or mor...

Nearly 20 years of satellite remote sensing at CGE

The first steps in satellite remote sensing at CGE were made in 1993, in the first years in close cooperation with the Remote Sensing Division of the Institute of Meteorology. The interest in the study of the atmospheric and surface properties using satellite images was first introduced in CGE by Ana Maria Silva and as a first year Master student, the first author here willingly accepted the challenge of develo...
