Laccases are multicopper oxidases that catalyze the oxidation of a broad range of substrates, typically phenols and anilines. Research on laccases in fungi, plants, and bacteria has indicated that they have roles in detoxification, pigmentation, wound healing, morphogenesis and lignin synthesis and degradation. However, there has been relatively little investigation on laccases that exist in in...

In this paper we describes the different algorithms for finding pitch markers in speech signal and it also explain how EEMD is better than EMD algorithm One of the major problem in EMD algorithm is mode mixing. EEMD algorithm helps in solving mode mixing problem. EEMD algorithm is a noise assisted data analysis (NADA) for extracting pitch information for the speech signal. In EEMD signal is dec...

Evidence for the formation of an unstable intermediate in the synthesis of quinolinate from aspartate and dihydroxyacetone phosphate by Escherichia coli was obtained using toluenized cells of nadA and nadB mutants of this organism and partially purified A and B proteins in dialysis and membrane cone experiments. The results of these experiments indicate that the nadB gene product forms an unsta...
