The Mozambican Roads Administration (ANE) has embarked on a project to establish a Road Research Centre (RRC) in Mozambique aiming to provide the basis for improving the long-term capacity to undertake relevant, high quality research relating to the road sector of Mozambique. This project forms part of the Africa Community Access Programme (AFCAP), which is a research programme supported by the Department of International Development (DFID) of the Government of the United Kingdom and managed by Crown Agents Ltd on behalf of DFID. CSIR, in association with LNEC has been commissioned by Crown Agents to provide Technical Assistance for phase 2 A of the project, which aims to address institutional issues relating to the RRC, draft a strategic research plan and develop a 5-year business plan for the RRC. This monthly progress report dated January 2014 summarises progress made with the identification of the road research needs of Mozambique; the production of recommendations on the institutional structure of the RRC; the establishment of the Road Research Technical Committee (RRTC) and the Road Research Steering Committee (RRSC); and the drafting of the business and strategic research plans for the RRC. The activities planned for February 2014 are also presented.

No presente relatório apresentam-se os dados meteorológicos do ano de 2013, recolhidos na estação meteorológica existente no Núcleo de Materiais Orgânicos do Departamento de Materiais do LNEC, em Lisboa.

Este relatório apresenta os resultados da monitorização do nível piezométrico e da qualidade daságuas subterrâneas efetuada nos furos e nos poços localizados no interior do perímetro do campusdo LNEC, bem como dos volumes de água drenados pelo sistema de bombagem instalado nas cavesdo edifício principal, durante o ano hidrológico 2012-2013.Apresentam-se as principais conclusões obtidas na perspetiva de compreensão da dinâmica entre osfenómenos de precipitação e a sua importância para a reposição dos níveis piezométricos, tendo emvista uma melhor gestão dos recursos hídricos subterrâneos do campus do LNEC

No âmbito das preocupações com a eficiência energética dos edifícios e com as exigências decorrentes do estabelecimento de requisitos mínimos de desempenho energético dos edifícios, baseados em níveis ótimos de rentabilidade em conformidade com as exigências da Diretiva 2010/31/EU recast, o LNEC colaborou na realização do estudo Português aplicável aos edifícios novos de comércio e serviços. Neste relatório, reúne-se parte das contribuições do LNEC para o estudo de edifícios de escritórios novos e apresentam-se as principais conclusões.

This is a mandatory delivery in the scope of European Union LIFE programme, consisting on the first activity report from LIFE Hymemb project and covering the period between January 1st 2014 and July 31st 2014. LIFE Hymemb general objective was to demonstrate the feasibility and sustainability of advanced membrane processes for the treatment of drinking water, in order to provide a safer and more resilient barrier against emerging contaminants, with lower environmental impacts. The project relied on long-term demonstration of the powdered activated carbon/ceramic microfiltration (PAC/MF) technology in Alcantarilha Water Treatment Plant. This report contains 7 chapters, including the executive summary, administrative part, technical part (actions reporting), financial part and annexes.

In this report we describe an experimental study carried out at LNEC within the research project DRYMASS (ref. PTDC/ECM/100553/2008). The study was aimed at evaluating the possibility of increasing the drying rate of porous building materials by means of nano-treatments. It was justified by previous results of other authors that observed an apparently unexplainable increase in the evaporation rate of natural stone after application of nano-calcium hydroxide solutions as consolidating agents. Two commercial treatments, consisting on alcoholic or aqueous suspensions of nano-lime or nanosilica, respectively, were tested on three porous building materials. The treatments are generally used for consolidation. The materials were a lime mortar and two natural stones (Ançã limestone and Bentheimer sandstone). It was concluded that neither of the nano-treatments hinders drying. However, they were also not able to increase the drying kinetics of any of the three substrates.

A Ria Formosa (sul de Portugal) é uma laguna muito produtiva, de elevada importância ecológica eeconómica. Assim, perceber os processos que afetam a produtividade deste ecossistema éfundamental para a sua gestão sustentável. O projeto COALA visa estudar a dinâmica de trocas denutrientes, clorofila e material particulado entre a Ria Formosa e o oceano adjacente, assim como ainfluência dos principais forçamentos (e.g. maré) nesta dinâmica, utilizando uma abordagemmultidisciplinar que combina modelação numérica e campanhas de campo. O modelo hidrodinâmicoSELFE foi aplicado na Ria Formosa, representando adequadamente os principais padrões decirculação. Este modelo foi combinado com um modelo de transporte lagrangeano para estudar ainfluência dos forçamentos ambientais na dinâmica de trocas lagoa

Relatório final do projeto PTDC/ECM/099121/2008

This report aims at performing a selection of a commercial powdered activated carbon (PAC) adequate to control a set of target emerging contaminants through PAC/nanofiltration (PAC/NF) hybrid process (Action B.1.1) and to perform a preliminary assessment of different PAC/NF configurations, which will be further tested in action B3 (Action B.1.2). A list of contaminants to be addressed was created, with these contaminants being classified into classes, based on their size, charge and hydrophilicity/hydrophobicity. Based on the available data of commercial carbons, a pre-selection of four carbons was performed. Adsorption isotherms and kinetics of the selected four representative contaminants supplemented to real effluent of
