Plant roots navigate in the soil environment following the gravity vector.Cell divisions in the meristem and rapid cell growth in the elongation zone propel the root tips through the soil.Actively elongating cells acidify their apoplast to enable cell wall extension by the activity of plasma membrane AHA H+-ATPases.The phytohormone auxin, central r

The high intensity proton accelerator complex (HIPA) at the Paul Scherrer Institute (PSI) delivers a 590 MeV CW proton beam with currents up to 2.4 mA (1.4 MW).Besides two spallation targets for thermal/cold neutrons (SINQ) and for ultracold neutrons (UCN), the Shaving Cream beam feeds two meson production targets Target M and Target E.The targets
