It has been known for some time that an Ss(3, 4, v) exists iff v is even. The constructions which prove this result, in general, give designs having repeated blocks. Recently, it was shown that a simple Ss(3, 4, v) exists if v is even and v 3.4 (mod 12). In this paper we give an elementary proof of

The existence of doubly near resolvable (v, 2,1)-BZBDs was established by Mullin and Wallis in 1975. In this article, we determine the spectrum of a second class of doubly near resolvable balanced incomplete block designs. We prove the existence of DNR(v,3,2)-BZBDs for v = 1 (mod 3), v 2 10 and v @

PbBi6O4 (PO4)4 obtained at room temperature is isomorphous with the high-temperature phase Bi6.67O4 (PO4)4. The Pb atom replaces 0.67 Bi in the same crystallographic site. The vanadate and arsenate with the composition PbBi6O4(XO4)4 were synthesized and yielded isomorphic phases at room temperature.
