Earthquake Mitigation in the Lisbon and Lower Tagus Valley area, Portugal
Carvalho, J. F.; Dias, J.; Pinto, Carlos; Cunha, T; Leote, J.; Vilanova, S.; Borges, J. F.; Ghose, R.; Narciso, J.The capital city of Lisbon and the Lower Tagus Valley region of central Portugal mainland are located in the Eurasian plate about 350 Km from the approximately E-W oriented Eurasia-Africa plate boundary. It is characterized by low slip-rates (<0.4 mm/year) and a moderate seismicity, occasionally shaken by some important historical earthquakes causing significant damages and economical losses. The most well know...

RANK, RANKL and osteoprotegerin in arthritic bone loss
Bezerra,M.C.; Carvalho,J.F.; Prokopowitsch,A.S.; Pereira,R.M.R.Rheumatoid arthritis is characterized by the presence of inflammatory synovitis and destruction of joint cartilage and bone. Tissue proteinases released by synovia, chondrocytes and pannus can cause cartilage destruction and cytokine-activated osteoclasts have been implicated in bone erosions. Rheumatoid arthritis synovial tissues produce a variety of cytokines and growth factors that induce monocyte differenti...

Synthesis, crystal growth and characterization of gamma-phase bismuth titanium ...
Lobato,A.R.; Lanfredi,S.; Carvalho,J.F.; Hernandes,A.C.Gallium solubility in the Bi12TiO20 (BTO) matrix was investigated by solid state reaction synthesis and Bi12Ti(1-x)Ga xO20 (BTGaO) single crystals were grown by Top Seeded Solution Growth (TSSG). We determined that it is possible to obtain a continuous solid solution from (x)Bi12TiO20: (1-x)Bi12[Ga0.7Bi0.3]O20 and that Ga replaces Ti in the BTO matrix giving Bi12Ti(1-x)Ga(x)O20 up to x < 0.2. BTGaO single cryst...
Vanadium characterization in BTO: V sillenite crystals
Carvalho,J.F.; Franco,R.W.A.; Magon,C. J.; Nunes,L.A.O.; Pellegrini,F.; Hernandes,A.C.Visible and Infrared Optical Absorption and Electron Paramagnetic Resonance (EPR) techniques have been used to characterize the intrinsic defects in sillenite type crystals: nominally pure Bi12TiO20 (BTO) and doped with vanadium (BTO:V). Optical quality crystals, with the composition Bi12.04±0.08Ti0.76±0.07V0.16±0.02O20, have been grown. Results obtained by these different techniques have shown unambiguously th...
