The present invention relates to excision of explant material comprising meristematic tissue from cotton seeds. The cam member 5 is non-rotatably connected to a rotor 3 through a connection shaft portion 52 piercing into a piston 4. A method of reducing separation of airflow from a surface of the vehicle includes generating plasma in air surrounding the surface at a position where the airflow would separate from the surface in the absence of the plasma. The monitoring controller monitors measurable characteristics associated with the executing application process, multi-function resources and tasks, each of the measurable characteristics being one of a status characteristic and a logistical characteristic.
