Utilization of P-NIPAM polymeric brushes in the development of thermo-responsive catalytic systems:A study of the effects of self-regulating polymers on molecular transport and reaction kinetics
A developing agenda for Lisbon within the twenty-first century
UID/SOC/04647/2013Divided by interdisciplinary realms of application, both climate change and urbanism are ultimately bound together by cause-and-effect in our ever mutable cities. Although suggested that cities are changing faster than Mankind have been able to adjust out thinking, the yearly dissemination scientific data on climatic change is continually improving the efficiency of urbanism to tackle new looming paradigms. Respectively, it is considered that urbanism encounters its greatest opportunities in this uncertain 'third modernity', where flexible approaches such as 'what if?' scenarios allow urbanism to continuously uphold the ever evolving identity and continuum within eventful horizons. This collaboration between these two interrelating realms of contemporary practice is currently being applied upon the case of Lisbon, where regional and local climate change scenarios are assessed in terms of their potential territorial impacts. This originated the opportunity to evaluate how the city components and functioning within its waterfronts shall be affected by climate change. Resultantly, and embedded within its niche, urbanism presents a new creative laboratory where flexible and innovative urban adaptation strategies can be developed to counter-act the impending impacts upon Lisbon within the XXI century.publishersversionpublishe

Sustainable development goals and climate change in Spanish technology disciplines’ curricula: From LOMCE to LOMLOE
Understanding the prevalence of climate change and sustainable development in the new curriculum of compulsory secondary education (ESO) and the baccalaureate is crucial for educational communities in Spain. However, there was a lack of studies that examined the integration of climate change and Sustainable Development Goals (SDGs) as cross-cutting themes in the new education framework, particularly in the technology disciplines. This study aimed to address this gap by conducting a comparative analysis of the new legislative content (LOMLOE) and the previous legislation (LOMCE). The analysis quantified the presence of keywords related to climate change and sustainable development in both legal texts, focusing on the definition of objectives, level skills, evaluation criteria, and blocks of knowledge. Additionally, the study assessed the inclusion of SDGs and the ethical implications associated with the use and production of technologies at both education levels. The analysis of the curriculum content revealed a significant presence of references to climate change, sustainable development, and SDGs throughout the LOMLOE curriculum, particularly in the baccalaureate. Notably, education’s role in addressing climate change and promoting sustainable development was explicitly recognized as an objective at this level. Regarding technology disciplines, LOMLOE placed considerable emphasis on fostering awareness of the environmental impact of technological development by introducing a new cross-level knowledge block named “Sustainable Technology”, spanning from ESO to the final courses of baccalaureate. This integration was further reinforced by evaluation criteria and specific skills that strongly aligned with sustainability principles, encouraging assessments centred around environmental awareness, ethical responsibilities, and sustainable entrepreneurship. Further studies are required to evaluate the effectiveness of incorporating SDGs and climate change into technology disciplines following the implementation of LOMLOE, with the aim of identifying best practices for effectively combatting climate change and promoting sustainability in technology education.Xunta de Galicia/FEDER | Ref.

Monitoring of atmospheric ozone and nitrogen dioxide over the south of Portugal by ground-based and satellite observations
The SPATRAM (Spectrometer for Atmospheric TRAcers Monitoring) instrument has been developed as a result of the collaboration between CGE-UE, ISAC-CNR and Italian National Agency for New Technologies, Energy and the Environment (ENEA). SPATRAM is a multi-purpose UV-Vis-scanning spectrometer (250-950 nm) and it is installed at the Observatory of the CGE, in Evora, since April 2004. A brief description of the instrument is given, highlighting the technological innovations with respect to the previous version of similar equipment. The need for such measurements automatically taken on a routine basis in south-western European regions, specifically in Portugal, has encouraged the development and installation of the equipment and constitutes a major driving force for the present work. The main features and some improvements introduced in the DOAS (Differential Optical Absorption Spectroscopy) algorithms are discussed. The results obtained applying DOAS methodology to the SPATRAM spectrometer measurements of diffused spectral sky radiation are presented in terms of diurnal and seasonal variations of nitrogen dioxide (NO2)and ozone (O-3). NO2 confirms the typical seasonal cycle reaching the maximum of (6.5 +/- 0.3) x 10(+15) molecules cm(-2) for the sunset values (PM), during the summer season, and the minimum of (1.55 +/- 0.07) x 10(+15) molecules cm(-2) for the sunrise values (AM) in winter. O-3 presents the maximum total column of (433 +/- 5) Dobson Unit (DU) in the spring season and the minimum of (284 +/- 3) DU during the fall period. The huge daily variations of the O-3 total column during the spring season are analyzed and discussed. The ground-based results obtained for NO2 and O-3 column contents are compared with data from satellite-borne equipment (GOME - Global Ozone Monitoring Experiment; SCIAMACHY - Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY; TOMS - Total Ozone Monitoring Spectrometer) and it is shown that the two data sets are in good agreement. The correlation coefficient for the comparison of the ground-based/satellite data for O-3 is of 0.97
Exposição Humana a Micotoxinas: biomonitorização humana e contribuição para a avaliação de risco da população europeia
As populações estão expostas diariamente a uma mistura complexa de substâncias químicas maioritariamente através da alimentação. Por forma a avaliar a exposição humana a estes contaminantes, é importante efetuar a sua biomonitorização, isto é, detetar a sua presença diretamente em amostras biológicas como sangue, cabelo, urina ou leite materno, ou prever precocemente os seus efeitos no organismo, com vista a reduzir a exposição aos químicos e contribuir para melhorar a saúde pública.
A Iniciativa HBM4EU (European Human Biomonitoring Iniciative) é um consórcio europeu que conta com a participação de 30 países, da Agência Europeia do Ambiente e da Comissão Europeia, e tem por objetivo utilizar a biomonitorização humana para avaliar a exposição humana a substâncias químicas, com vista a uma melhor compreensão dos impactos associados na saúde e à melhoria da avaliação dos riscos químicos. Um dos contaminantes químicos estudados neste projeto europeu são as micotoxinas, compostos naturais produzidos por fungos e presentes maioritariamente em alimentos.This project has received funding from
