The focal mechanism provides seismological constraints on the geological faults that generate the earthquakes and thus is important for regional seismotectonic research. Focal mechanism calculation ...

Design, fabrication and characterization of a compatible multi-polarity control signals multi-octave 180/spl deg/ MMIC phase shifter with either digital or anal ...

The desulfurization activity and selective hydrogenation of Cu/ZnO adsorbents on the different polarity ratios of ZnO as supports was investigated in reactive adsorption desulfurization. The ZnO ...
