A canola protein isolate useful in aquaculture is formed by a procedure in which canola oil seed meal is extracted to cause solubilization of protein in the canola oil seed meal to form an aqueous protein solution having a protein content of about 5 to about 40 gL and a pH of about 5 to about 6. The method includes running a lithographic model for a target tool and running a lithographic model on the matching tool for a plurality of different settings using lens numerical aperture, numerical aperture of the illuminator and annular ratio of a pattern which is produced by an illuminator. The monitoring database includes a list of contacts to be contacted in an emergency for each user of each user device. The passive torque device has a pair of null positions or detents at the retracted and extended positions.
