In order to elucidate the role of Cyp19a in sex differentiation of Schizothorax kozlovi, the full length cDNA of Cyp19a was cloned from the mature ovary of S. kozlovi by using rapid amplification of cDNA ends method, and then its relative mRNA expression levels among tissues and temperature groups were determined by using quantitative real-time PCR. The complete Cyp19a cDNA of 1795 bp of S. kozlovi...
The generation mechanism of Lg wave from underground nuclear explosion is still not clear at present. The general viewpoint is that the S wave generated by the near-source scattering of explosion-generated Rg appears to be the primary contributor to the low-frequency Lg (0.2–2.0 Hz) from nuclear explosions. The viewpoint is supported by the analysis of regional data from several Yucca Flats, NTS explosions...
