A conductive member is disposed between a secondary spool and a high tension terminal to shield the wire connecting the secondary coil and the high tension terminal. Also, a diagnostically determined refractive power map for the cornea is created. Placing information of interest to the user in the idle screen makes that information instantly accessible without the user having to navigate to the required function and select it. Full voltage is maintained to a remaining portion of the processor, so that the remaining portion of the processor can continue to operate while the instruction-processing portion of the processor is in reduced power mode. The invention furthermore relates to novel nucleic acid sequences which code for the \u03946-desaturases used in the method, gene constructs comprising these nucleic acid sequences, a vector and transgenic plants comprising at least one nucleic acid sequence or a gene construct. Vaccines composed of r56 protein variants are also disclosed.
