Still entrenched in the conflict/cooperation dichotomy? EU–Russia relations and the Ukraine crisis

The article highlights that the traditional conflict/cooperation dichotomy which characterised the dynamic of European Union (EU)–Russia relation during the post-Cold War period has remained stable throughout the Ukraine crisis. It identifies a pattern of continuity rather than change in the main characteristics of the traditional conflict/cooperation dichotomy: the post-Cold War order on the European continent, values and worldviews, perceptions of self and other, and policies towards each other and post-Soviet space. Secondly, in tune with neoclassical realism the article aims to account for the relative persistence of the conflict/cooperation dichotomy. It argues that the dynamic of EU–Russia relations remained rather stable due to the fact that neither the EU nor Russian foreign policy has undergone major transformations (of both power, scope and organisation) that would provide incentive or constrains for a complete overhaul of the conflict/cooperation dichotomy. Moreover, the article claims that the relative stability of world politics since the start of the Ukraine crisis has not given any the EU and Russia incentives – or constrained them – to seek to change the overall dynamic of their relationship.

Influência de polímeros superabsorventes na retracção de argamassas

Hoje em dia, o desenvolvimento dos superplastificantes permite a produção de betões com menor razão água/cimento. Ao usar razões água/cimento mais baixas, os materiais científicos apresentam maior tendência para fissurar devido à retracção autogénea. Este trabalho apresenta um estudo sobre a utilização de polímeros superabsorventes (SAP) no controlo da retracção. O uso de SAPs em materiais comentícios atenua a retracção autogénea pois estes produtos permitem o fornecimento interno de água. Estes produtos podem também afectar outras propriedades, afectando as características mecânicas e a trabalhabilidade. Para análise do efeito dos SAP foram estudadas argamassas com várias concentrações deste produto, tendo como referência argamassas semelhantes sem SAP, determinando-se as retracções autogénea e total, a resistência à compressão e o módulo de elasticidade. Além de SAP, foi também utilizado um agregado leve, um outro tipo de introdutor de água, para comparação com os polímeros em estudo. /ABSTRACT: This work presents a study on the use of superabsorbent polymers (SAP) in the control of shrinkage. The use of SAPs in cementitious materials reduces the autogenous shrinkage because these products enable the internal supply of water. These materials can also affect other properties such as mechanical properties and workability. To analyze the effect of SAP, mortars containing various concentrations of this product were studied, in comparison with reference mortars without SAP. The tests performed were autogenous and total shrinkage, compressive strength and modulus of elasticity. Besides SAP, it was also used a lightweight aggregate, another type of internal supply of water, for comparison with the polymers under study.
