Evidence for sporadic Coxiella burnetii excretion in sheep milk, central Portugal
Pires, Humberto; Silva, S. Santos; Cruz, A.; Cardoso, Luís; Lopes, A.P.; Pereira, M.A.; Nóbrega, C.; Mega, A.C.; Santos, C.; Cruz, R.; Esteves, F.Coxiella burnetii, the causative agent of Q fever, is a globally distributed zoonosis, with cattle, sheep, and goats considered the main reservoirs of the disease (Agger et al,., 2013; Bento et al., 2023). Human transmission primarily occurs through inhaling infections aerosols from milk, faeces, urina, and birth products from infected ruminants. This study used a 2-year longitudinal approach to investigate C. ...
Using gradient forest to predict climate response and adaptation in Cork Oak
Vanhove, M.; Pina-Martins, F.; Coelho, A.C.; Branquinho, C.; Costa, A.; Batista, D.; Silva, A.; Sousa, P.; Henriques, A.; Marques, I.; Belkadi, B.Climate change is impacting locally adapted species such as the keystone tree species cork oak (Quercus suber L.). Quantifying the importance of environmental variables in explaining the species distribution can help build resilient populations in restoration projects and design forest management strategies. Using landscape genomics, we investigated the population structure and ecological adaptation of this tre...
Organic light emitting diodes with europium (III) emissive layers based on β-di...
Santos, G.; Fonseca, F.J.; Andrade, A.M.; Deichmann, V.; Akcelrud, L.; Braga, S.S.; Coelho, A.C.; Gonçalves, I.S.; Peres, M.; Simões, W.; Monteiro, T.This work shows a comparative study of organic light emitting diodes based on four different europium complexes with the general formula, Eu(CLs)3bipyridine, where the central ligands are DBM [tris(dibenzoylmethane)], TTA [tris(1-(2-thieneyl)-4,4,4-trifluoro-1,3-butanedione)], NTA [tris(1-(2-naphthoyl)-3,3,3-trifluoroacetone)] and BTA [tris(1-(2-benzoyl)-3,3,3-trifluoroacetone)]. All devices have a driving volt...
Luminescence properties of the TRIMEB inclusion compound of a europium tris-β-d...
Braga, S.S.; Coelho, A.C.; Gonçalves, I.S.; Santos, G.; Fonseca, F.J.; Andrade, A.M.; Peres, M.; Simões, W.; Monteiro, T.; Pereira, L.The adduct TRIMEB:Eu(BTA)3 · 2H2O was prepared and primarily characterized by photoluminescence (PL), and compared with free Eu(BTA)3 · 2H2O. Both spectra show the Eu3+ ion emission, with subtle differences between lines for the free and encapsulated complex. The temperature dependence and chemical stability were studied, taking into account (in the latter case) the PL changes with time. The use of this new mat...
