A comparative analysis of geodetic versus seismic moment-rate estimations makes it possible to distinguish between and aseismic deformation, define the style also reveal potential gaps. This has been performed for Egypt where present-day tectonics seismicity result from long-lasting interaction Nubian, Eurasian, Arabian plates. The data used comprises all available geological tectonic informati...

This study reports for the first time the production of chicken germline chimeras by transfer of embryonic germ (EG) cells into recipient embryos of different strain. EG cells were established by the subculture of gonadal tissue cells retrieved from stage 28 White Leghorn (WL) embryos with I/I gene. During primary culture (P(0)), gonadal primordial germ cells (gPGCs) in the stromal cells began ...
