Decision-making criteria to shape mulching techniques for fire-prone landscapes
Petratou, Dapne; Nunes, J.P.; Guimarães, Maria; Prats, SergioContext Wildfires have severe impacts on landscapes’ hydrological and sediment processes. They are linked to events such as flash floods and droughts, and high erosion rates which lead to loss of soil organic matter and detachment of seeds and seedlings. Mulching is an effective measure implemented directly after a fire to reduce soil erosion and increase soil water retention. However, its implementation has pr...
Rethinking ecosystem service indicators for their application to intermittent r...
Pastor, A.V.; Tzoraki, O.; Bruno, D.; Kaletová, T.; Mendoza-Lera, C.; Alamanos, A.; Brummer, M.; Datry, T.; De Girolamo, A.M.; Jakubínský, J.; Logar, I.In these times of strong pressure on aquatic ecosystems and water resources due to climate change and water abstraction, intermittent rivers and ephemeral streams (IRES) (rivers that periodically cease to flow and/or dry) have become valuable assets. Indeed, not only do they supply water but they also offer services for humanity. Despite a growing recognition towards IRES, information for assessing their ecosys...
Sandwiched composites in aerospace engineering
Nunes, J.P.; Silva, João F.This chapter considers sandwiched composites used in aerospace applications. It discusses new developments in the types of face and core materials, production methods and joining and repair techniques. It also discusses various properties as well as their main design methods. Both existing and future applications of sandwiched composites are discussed.
Pultrusion of fibre reinforced thermoplastic pre-impregnated materials
Novo, P.J.; Silva, João F.; Nunes, J.P.; Marques, A.T.Fibre reinforced thermoplastic pre-impregnated materials produced continuously by diverse methods and processing conditions were used to produce composites using pultrusion. The processing windows used to produce these materials and composites profiles were optimized by using the Taguchi/DOE (Design of Experiments) methods. Those composites were then submitted to mechanical testing and microscopy analysis. The ...
Impacts of climate and land use changes on the hydrological and erosion process...
Serpa, D.; Nunes, J.P.; Santos, J.; Sampaio, E.; Jacinto, R.; Veiga, S.; Lima, J.C.; Moreira, M.; Corte-Real, J.; Keizer, J.J.; Abrantes, N.The impacts of climate and land use changes on streamflow and sediment export were evaluated for a humid (São Lourenço) and a dry (Guadalupe) Mediterranean catchment, using the SWAT model. SWAT was able to produce viable streamflow and sediment export simulations for both catchments, which provided a baseline for investigating climate and land use changes under the A1B and B1 emission scenarios for 2071–2100. C...

Satellite-derived estimation of environmental suitability for malaria vector de...
Benali, Akli; Nunes, J.P.; Freitas, F.B.; Sousa, C.A.; Novo, M.T.; Lourenço, P.M.; Lima, J.C.; Seixas, J.; Almeida, A.P.G.Malaria was endemic in Europe for more than two millennia until it was eradicated in the 1970s. Recent autochthonous cases registered in Greece have increased the awareness regarding the threat of malaria re-emergence in Southern Europe. Currently, the presence of competent vectors, suitable environmental conditions and the evidences of a changing climate may increase the widespread re-emergence of malaria in S...
