The 33 ku protein,prepared from NaCl-treated PSⅡ particles,has shown an single band by SDS-PAGE.After being dialyzed against the low-osmotic medium at 4℃,it h
In2O3, MgO and Fe2O3 were doped in LiNbO3 and Czochralski method was used to grow In:Mg:Fe:LiNbO3 crystals. The OH- extension transmission spectra, light scatte
Here we report the first direct Rb-Sr dating of pyrites and ores using sub-sampling from lode gold deposits in Linglong, Jiaodong Peninsula, which is a supra-la
A class of higher order neutral difference equations is considered and some sufficient conditions are obtained for all solutions to oscillate or tend to zero.
Stability criteria for a weak relativistic beam-plasma interaction in a strong magnetic field are found.Two beam modes occur,ω≈kzc and ω≈kzc-ωc.The dispers
A new approach to model viscosity in the conservation of momentum equations is presented and discussed. Coefficient of viscosity is modeled in such a way that i
Because of wide variation in gray levels and particle dimensions and the presence of many small gravel objects in the background, as well as corrupting the imag
