The purified nerve growth factor consisting of 116 amino acids from the venom of Naja kaouthia snake was fragmented by trypsin digestion. The identifier unit may be configured to identify an assignment type of an assignment of a variable in a part of a program code. The transmission element transmits force to move the instrument carrier so that a dental instrument received in the instrument carrier executes a rotating, reciprocating andor vibrating working movement. A first plurality of three weight members is disposed in the rear member, and each of these three weight members is each made of high density material, such as tungsten. At least one first nozzle is arranged to spray mainly in the area between the object to be extinguished, such as an aircraft, and the floor of the storage space or equivalent at least in a horizontal plane mainly in one first direction. In particular, the invention provides a method of modifying the fiber content andor fiber composition andor starch content andor nitrogen content andor non-sulfur-containing amino acid composition andor anti-nutritional protein content andor fatty acid content andor fatty acid composition of the storage organs of a plant.
