since nox family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. in the off-gases of internal combustion engines running with oxygen excess, non-thermal plasmas (ntps) have an oxidative potential, which results in an effective conversion of no to no2. ...

Nonallelic gene conversion has been proposed as a major force in homogenizing the sequences of paralogous genes. In this work, we investigate the extent and characteristics of gene conversion among gene families in nine species of the genus Drosophila. We carried out a genome-wide study of 2855 gene families (including 17,742 genes) and determined that conversion events involved 2628 genes. The...

interesting manner, that one gains pleasure as well as profit from reading them. Those who are not already acquainted with .the author's views should procure this book, which presents them mcst lucidly, and at moderate length. Professor Janet's work has done much to elucidate hysteria by a process of analysis of the psychical phenomena which lie at its root. We may remind our readers that accor...

Very rapid rates of gene conversion were observed between duplicated alpha-amylase-coding sequences in Drosophila melanogaster. This gene conversion process was also seen in the related species Drosophila erecta. Specifically, there is virtual sequence identity between the coding regions of the two genes within each species, while the sequence divergence between species is close to that expecte...
