The formation of PZT from the oxides Pb3O4, TiO2 and ZrO2 in the presence of NiO, Fe2O3 and Ta2O5 additives has been investigated by thermal analysis...

The plate hierarchical finite element in this paper utilizes trigonometric hierarchical shape functions rather than the more usual forms of orthogonal...

We construct a sequence ofd-dimensional classical orthogonalpolynomials (d[ges]2) that generalize the Gegenbauer polynomials.The cased=2 is fully stud...

A V(IV) tetraphosphate K2(VO)2P4O13has been synthesized for the first time, and crystals of this new phase can be grown in air. It crystallizes in the...

At some Early Palaeolithic sites (e.g. Ain Hanech, Algeria and el ’Ubeidiya, Israel), archaeologists have uncovered interesting and enigmatic ar...
