We critically evaluate the isovector GMO sumrule for the charged πNN coupling constant using recent precision data from π − p and π − d atoms and with careful attention to systematic errors. From the π − d scattering length we deduce the pion-proton scattering lengths

Phytoextraction is an in situ decontamination technique using metal accumulating plants and appropriate soil amendments to transport and concentrate metals from the soil into the aboveground parts of plants, which are harvested with conventional agriculture methods. Since most of the metal hyperaccumulating plants only produce very low biomass, and most of plants producing high biomass accumula...
