A method to detoxify municipal sewage sludge containing heavy metals comprises the steps of mixing sewage sludge (CS), at least one catalytic oxidant (CO) such as a ferric salt, at least one regenerative oxidant (RO) and an acid (A) to form a reacting slurry having a solids fraction and a liquid fraction and, after a suitable retention time, separating the solids fraction from the liquid fraction....

A method of detecting coded labels with at least two amorphous magneto-elastic tapes in a detection zone with a biasing magnetic field is described. The resonance frequencies and the modulation frequencies for each tape are detected at the same time. A tape whose detected resonance frequency is the same as the detected modulation frequency for another tape is registered as belonging to the same la...

An optical body 1 in an intraocular prosthetic lens is made up of a first planoconvex optic element 3 and a second planoconvex optic element 4, both interconnected by their bases. An optic axis 5 of the first planoconvex optic element 3 is offset with respect to the optic axis 6 of the second planoconvex optic element 4.
