Abstract: An artificial fishing lure for use in trolling. The lure has a body with a leading edge, a tail, a top surface, a bottom edge, a first side and a second side. At least three line passages are positioned in spaced relation along the top edge between the leading edge and the tail; including a lead line passage, a mid-body line passage, a knot hole line passage. A holding clip is positioned on the second side of the body next to the knot hole passage. The holding clip is adapted to maintain a shank of a hook in friction fit engagement with the hook generally oriented toward the tail when casting or trolling. The clip releases the hook from the body when a fish strikes. The body holds its position on the line when the line is taut due to friction resulting from the manner the line is woven through lead line passage, the mid-body line passage and the knot hole line passage.

Abstract: A nuclear quadrupole resonance (NQR) or nuclear magnetic resonance (NMR) apparatus which includes a probe and a variable impedance spectrometer. The probe emits a signal towards a specimen which causes the specimen to produce a resonance signal. After a recovery period from emitting the signal, the probe receives the resonance signal produced by the specimen. The variable impedance spectrometer is connected to the probe and has a total Q factor therewith. The spectrometer causes the total Q factor during the recovery period to be lower than the total Q factor before and after the recovery period by varying the impedance of the spectrometer, without changing the electrical configuration of the probe.
