Kanoun-Boulé, Myriam; Vicente, Joaquim A. F.; Nabais, Cristina; Prasad, M. N. V.; Freitas, Helenahttp://www.sciencedirect.com/science/article/B6T4G-4TGXP9V-1/2/0652ab94eb95eab94ea56a82c424997b
Fases portadoras do arsénio em solos da área mineira de São Domingos e em solos...
Abreu, Maria Manuela; Santos, E.C.; Magalhães, M.C.F.; Nabais, C.São Domingos mining area is located in the Iberian Pyrite Belt, in south-east Portugal. Intensive gossan gold, copper and silver mining was done in roman times. More recently, mining activities were concentrated in the copper, zinc, arsenic and lead rich sulfide orebodies. To evaluate arsenic hazard, soils developed on the gossan mine waste piles were analysed, using as reference non- contaminated soils from Po...
Capacidade de absorção do chumbo por plantas do género Cistus espontâneas em am...
Abreu, Maria Manuela; Santos, E.S.; Anjos, C.; Magalhães, M.C.F.; Nabais, C.Mining activity can give rise to large quantities of chemically unstable waste rocks and tailings which can drain potential environmentally harmful lixiviates rich in chemical elements. Plants growing in such environments can minimize chemical, physical and visual negative impacts. To evaluate lead absorption by native Cistus growing in Braçal (NW Portugal) and São Domingos (SE Portugal) mining areas, Cistus in...
Sawtooth, Neo-Classical Tearing Mode and Error Field Studies in JET
T. C. Hender; O. Sauter; B. Alper; C. Angioni; M. Baar; M. Benedetti; P. Belo; M. Bigi; D. N. Borba; T. Bolzonella; R. Budny; R. J. ButteryA range of ITER relevant plasma stability issues have been studied in the JET tokamak; these include the effects of fast particles on sawteeth, control of NTMs via sawteeth seeds, scaling of (2,1) NTM thresholds and the effect of error fields on plasma rotation and vice-versa. The sawtooth studies have examined both the effects of ICRF and NBI fast particles, and models used for ITER predictions have been valid...
