    Notes: Abstract A new polyazoxyphosphonate was synthesized by reaction of 4-4′-dihydroxyazoxybenzene and dichlorophenyl phospine oxide by interfacial polycondensation using a phase transfer catalyst. The polymer was characterized and the results obtained by various analytical techniques indicate that it is mostly amorphous, low molecular weight and soluble in organic solvents such as DMF, DMAC, NMP, etc. The high char residue (∼40%) and limiting oxygen index indicate flame retardancy of the polymer which is due to phosphorus. Thermal stability of this polymer is moderate. TheT g appears to be at 152°C.

    Notes: Summary Three populations (Poliya, Deshi, and Tiyor) of the Koch ethnic group have been studied for the distribution of three serum protein and four red cell enzyme polymorphisms. There was no significant difference in the allelic frequencies of these systems in the three populations of the Koch ethnic group. The overall gene frequencies were as follows:Hp 1, 0.21;Gc 1F, 0.34;Gc 1s, 0.36;Gc 2, 0.30;Tf C1, 0.66;Tf C2, 0.26;Tf C3, 0.001;Tf D, 0.06;GLO 1, 0.21;PGI 2, 0.04;AK 2, 0.01;PGM 1+, 0.80;PGM 1−, 0.06;PGM 2+, 0.11 andPGM 2−, 0.02. The phenotypic distribution at all the loci was at Hardy-Weinberg equilibrium.
