Influence of seismic activity on the atmospheric electric field in Lisbon (Port...
Silva, H.G.; Oliveira, M.M.; Serrano, C.; Bezzeghoud, M.; Reis, A.H.; Rosa, R.N.; Biagi, F.In the present study, we considered the influence of seismic activity on the atmospheric electric field recorded at Portela meteorological station (Lisbon, Portugal) for the period from 1955 to 1991. To this end, an exploratory method was developed, which involved the selection of events for which the distance from the atmospheric electrical field sensor to the earthquake epicenter is smaller than the preparati...
Physics of Seismo-electromagnetic Phenomena
Silva, Hugo Gonçalves; Bezzeghoud, Mourad; Borges, J.F.; Bento, C.; Moita, P.; Serrano, C.; Reis, A.H.; Rosa, R.N.; Tlemçani, M.; Biagi, P.F.The seismo-electromagnetic phenomena (SEMG) are integrated in a relatively recent research field that studies diverse phenomena such as: unusual seismo-electrical signals [1], abnormal ultra-low-frequency (ULF) seismo-electromagnetic emissions [2], very-low-frequency (VLF) and low-frequency (LF) radiobroadcast anomalies associated with ionosphere perturbations [3], variation of total electron content of the ion...
Remoção e metabolização de Dexametasona por plantas da família das macrófitas
Silva, M.; Serrano, C.; Pires, T.; Carvalho, A. P.; Dordio, A. V.; Pinto, A. P.; Teixeira, D. M.A presença de compostos farmacêuticos e seus metabolitos no ambiente aquático tornou-se nos últimos anos um problema ambiental emergente. Assim, tornou-se essencial o desenvolvimento de processos de remoção mais eficientes, como o tratamento de efluentes com leitos construídos de macrófitas (LCM) que, em muitos casos, tem permitido a obtenção de águas residuais finais de boa qualidade. Este trabalho teve como o...
Atmospheric electrical field suppression in the time of the M =4.1 Sousel earth...
Silva, Hugo Gonçalves; Serrano, C.; Reis, A.H.; Bezzeghoud, Mourad; Rosa, R.N.; Borges, J.F.; Caldeira, B.; Tlemçani, M.In recent years different phenomena associated with seismic events have been referred in the literature. These include: unusual ultra-low-frequency electromagnetic emissions [1]; anomalies in very-low and low-frequencies radio transmissions [2]; variation of the ionosphere total electron content [3]; and anomalous levels of different geochemical elements (in particular radon) in the earthquake preparation zone ...
