Abstract: A method for making a genetically modified plant expressing a transgene with a desirable trait that is transmitted poorly, the trait being lost in ensuing generations due to excision of the transgene. The method involves hybridizing a first plant regenerated from a plant cell that has been transfected with DNA  sequences comprising a first gene whose expression results in an altered plant phenotype linked to a promoter, the cassette of gene and promoter flanked on each side by the first specific excision sequences, a second gene that encodes a recombinase specific for the first specific excision sequences linked to a transiently active promoter, the gene and promoter being separated by a blocking sequence flanked on each side by the a second specific excision sequeces to a second plant regenerated from a second plant cell that has been transfected with DNA sequences comprising a third gene that encodes a recombinase specific for the second specific excision sequences linked to a promoter, and growing a hybrid plant from the hybrid seed. Alternatively, a single plant can be stably transformed with all of the above sequences to effect the same result.

Patent CA-2438732-A1 (CA)
Inventor: PABON JAHIR
IPC: G10K11/178
Filed: 2003-08-25
Abstract: A sonic logging tool that can be positioned within a fluid-filled borehole includes an axially distributed active vibration control system to reduce tool borne noise. The tool includes an acoustic transmitter, an axial array of acoustic receivers, and actuator assemblies that are coupled to cancel tool mode vibrations at stations along the receiver section of the tool. In a preferred embodiment, force is applied in feedback mode based on tool mode vibrations sensed at each station. The force at each station is applied by a real-time computational algorithm using feedback. The feedback includes weighting to accommodate monopole or dipole tool mode vibration. The computational algorithm includes FIR processing of signals received from a vibration sensor assembly. The force applied at a given station is a function of tool mode vibration measured at that station and the predetermined values of a set of FIR filter coefficients associated with the given station.  The predetermined FIR filter coefficients are determined by an iterative optimization technique.  Alternatively, the force at each station may be applied using feed-forward.
