Neutrino Magnetic Moment and the Process $\nu e \rightarrow \nu e \gamma$
The contribution of a neutrino magnetic moment $\mu_{\nu}$ to the cross section of the process $\nu e^{-}\rightarrow \nu e^{-} \gamma $ has been calculated and compared with the Standard Electroweak one. The radiative process allows to reach low enough values of $Q^2$ without the need to operate at very small energies of recoil electrons. Regions in the phase space which are more favourable to set bounds on $\mu_{\nu}$ are suggested.
Factors Influencing Digitalis Obscura Mesophyll Protoplast Development
In a previous work (1), we found that a combination of liquid-over-agar-solidified MS (2) modified medium was superior to either all liquid or all solid medium for culture of Digitalis obscura L. mesophyll protoplasts. In order to achieve optimum culture conditions we now report on the influence of a different gelling agent (agarose) as well as the effect of several nutrient media on D. obscura mesophyll protoplasts development.
