Portuguese SMEs: Strategies for collaborative R&D and participation in the fram...
Abreu, R.; Antunes, J.; Escada, M.; Pádua, M.; Patrício, M. T.The European Union Framework Programme can create and/or strengthen research networks and cooperation, namely between SMEs and higher education institutions. However, in Portugal, SMEs represent only 16,7% of allocated funds, falling below the European Commission’s target (Agência Nacional de Inovação, 2020). Low SME participation can result from factors particularly related to SMEs, such as organizational char...
R&D cooperation and innovation networks: Lessons from SME participation in H2020
Abreu, R.; Antunes, J.; Escada, M.; Pádua, M.; Patrício, M. T.Portuguese SMEs are ‘catching-up’ to the European Commission’s goal of 20% for SME participation in H2020, representing16,7% of allocated funds.. Previous R&D experience, and especially R&D cooperation, have been identified as key determinants of participation in Framework Programmes, such as H2020. Thus, it is important to know SMEs that engage in these experiences and the drivers that lead them to it. This pa...
Overcoming environmental problems of biocides: Synthetic bile acid derivatives ...
Neves, A.R.; Almeida, J.R.; Carvalhal, F.; Câmara, A.; Pereira, S.; Antunes, J.; Vasconcelos, V.; Pinto, M.; Silva, E.R.; Sousa, E.Marine biofouling represents a global economic and ecological challenge. Some marine organisms produce bioactive metabolites, such as steroids, that inhibit the settlement and growth of fouling organisms. The aim of this work was to explore bile acids as a new scaffold with antifouling (AF) activity by using chemical synthesis to produce a series of bile acid derivatives with optimized AF performance and unders...
Relevância do VANT no processo de representação e produção de Arquitetura
Antunes, J.; Eloy, S.; Pinto, P.The emergence of the airplane as an influential element for architects of the twentieth century’s modern movement, has transformed the knowledge and modes of interpreting the landscape, which has a reflection in planning and interacting with the territory. In the 21st Century, the relevance of the aircraft is perpetuated with the emergence of the Unmanned Aerial Vehicles (UAV) - commonly designated as drones - ...
Marine biofilms: diversity of communities and of chemical cues
Antunes, J.; Leão, P.; Vasconcelos, V.Surfaces immersed in seawater are rapidly colonized by various microorganisms, resulting in the formation of heterogenic marine biofilms. These communities are known to influence the settlement of algae spores and invertebrate larvae, triggering a succession of fouling events, with significant environmental and economic impacts. This review covers recent research regarding the differences in composition of biof...
A multi-bioassay integrated approach to assess the antifouling potential of the...
Antunes, J.; Pereira, S.; Ribeiro, T.; Plowman, J.E.; Thomas, A.; Clerens, S.; Campos, A.; Vasconcelos, V.; Almeida, J.R.The cyclic peptides portoamides produced by the cyanobacterium Phormidium sp. LEGE 05292 were previously isolated and their ability to condition microcommunities by allelopathic effect was described. These interesting bioactive properties are, however, still underexplored as their biotechnological applications may be vast. This study aims to investigate the antifouling potential of portoamides, given that a cha...
Domestic violence: The impact of a nature-based holistic development program on...
Silva, A.; Antunes, J.; Peixoto, J.; Gonçalves, Mariana; Alves, F.; Silva, J.; Garrido, N.; Matos, MarleneSeveral studies have highlighted the benefits of nature for human well-being. Nevertheless, the incorporation of nature as an operative resource in social support processes of vulnerable groups such as domestic violence victims is not a common practice. The complexity and prevalence of domestic violence result in a growing need for innovative intervention modalities that can contribute to provide more effective...
Potential of synthetic chalcone derivatives to prevent marine biofouling
Almeida, J.R.; Moreira, J.; Pereira, D.; Pereira, S.; Antunes, J.; Palmeira, A.; Vasconcelos, V.; Pinto, M.; Correia-da-Silva, M.; Cidade, H.Biofouling represents a major economic, environmental and health concern for which new eco-friendly solutions are needed. International legislation has restricted the use of biocidal-based antifouling coatings, and increasing efforts have been applied in the search for environmentally friendly antifouling agents. This research work deals with the assessment of the interest of a series of synthetic chalcone deri...
Sphaerocyclamide, a prenylated cyanobactin from the cyanobacterium Sphaerosperm...
Martins, J.; Leikoski, N.; Wahlsten, M.; Azevedo, J.; Antunes, J.; Jokela, J.; Sivonen, K.; Vasconcelos, V.; Fewer, D.P.; Leão, P.N.Cyanobactins are a family of linear and cyclic peptides produced through the post-translational modification of short precursor peptides. A mass spectrometry-based screening of potential cyanobactin producers led to the discovery of a new prenylated member of this family of compounds, sphaerocyclamide (1), from Sphaerospermopsis sp. LEGE 00249. The sphaerocyclamide biosynthetic gene cluster (sph) encoding the n...
A study on the use of eye tracking to adapt gameplay and procedural content gen...
Antunes, J.; Santana, P.This paper studies the use of eye tracking in a First-Person Shooter (FPS) game as a mechanism to: (1) control the attention of the player’s avatar according to the attention deployed by the player; and (2) guide the gameplay and game’s procedural content generation, accordingly. This results in a more natural use of eye tracking in comparison to a use in which the eye tracker directly substitutes control input...
