OSCILLATION OF THREE DIMENSIONAL NEUTRAL DELAYDIFFERENCE SYSTEMS

This paper deals with the some oscillation criteria for the three dimensional neutral delay difference system of the form Δ xn+pnxn-k =bnynα Δ yn =cn znβ Δ(zn)=-anxn-l+1γ , n=1,2,…, Examples illustrating the results are inserted

On the equisummability of Hermite and Fourier expansions

We prove an equisummability result for the Fourier expansions and Hermite expansions as well as special Hermite expansions. We also prove the uniform boundedness of the Bochner-Riesz means associated to the Hermite expansions for polyradial functions

The trends of infestation of Haplothrips ganglbaueri on Oryza sativa and the weed Echinochloa crusgalli in paddy fields are discussed, along with its biological and taxonomical aspects

Preliminary study on isozyme variation in silkworm germplasm of bombyx mori (L.) and its implication for conservation

Genetic diversity within and among twelve silkworm Bombyx mori races was investigated using metabolic enzymes viz., a-esterase (a- EST), b-esterase (b-EST), glucose fYphosphate dehydrogenase (G6PD) and acid phosphatase (ACP). A perusal of genetic diversity within and among races indicated that 28% of the observed variation occurred among races and the rest of the variation (72%) within races. The average rate of gene flow between pair wise comparisons of the twelve races was found to be very high (0.62). Genetic relatedness of the twelve races revealed fly the UPGMA dendrogram, showed genetic grouping of races in six clusters. NB4D2 and NB18 are genetically similar while BL-24 and Nistari are genetically distant races. Populations of silkworm races ]-112 and NB4D2 showed the highest genetic diversity, %polymorphism and more alleles, respectively. Their rich genetic diversity needs to be exploited in conservation and breeding programme
