metals in sludge extracted by BCR sequential extraction procedure (F1: Acid soluble/exchangeable fraction; F2: Reducible fraction; F3: Oxidizable fraction; F4: Residual fraction) Fractions of Cu, Zn, Pb... proportion of metal extracted from F1 (12.70% to 42.29%), F2 (9.6% to 57.85%), and F3 (15.10% to 40.20%). Zn thus appeared to have high bioavailability and potential ecotoxicity, a result that reflects......

The maximum likelihood (ML) multiuser detector estimated the vector b...; (2) with the constraint where Re{?} denoted the real part of a complex number. The ML data estimates were given by  ......
tests, such as the shear test, are also required for enhanced material models [3-5]. However, complex models require a considerable number of parameters to be determined, which leads to a high cost... with large strain, non-uniform deformation and complex deformation states. Some works have reported in this direction [4,9-16]. Since the punch stretch test can be introduced to evaluate the effect......
