The invention provides methods and oligonucleotide primers for assaying Brassica napus plants for the presence or absence of mutations that confer resistance to imidazolinone herbicides. Inner columns can be provided for supporting the housing and for the ground connection; outer columns can be provided for the electrical connection and are connected to the component structures by means of conductor tracks that are electrically insulated from the frames. The lipid and polyamine combination displays physical attributes that mimic the crystalline structures of saturated lipids and fats without the incurring the associated negative health implications of such saturated lipids and fats. When the coating solution contains a phosphorus source, the molality of protons is 0. The processor, or another entity, may be used to determine whether the current state of the processor is the same as said one of the states used to pre-decode the instructions when one of the pre-decoded instructions in the cache is needed by the processor.
