A method of magnetic resonance analysis of a body having therein at least one molecular species and water is disclosed. The expression cassettes may include various elements for improved expression, stability of the expressed protein or efficient purification of the expressed protein, including signal sequences, protease cleavage sites for release of the target protein, trafficking peptides for trafficking of the expressed protein to various plant compartments, andor various tags. A property of the wind approaching the wind turbine may be determined based on the property of wind measured at at least two predefined locations.
