In the disk clamping mechanism of the present invention, a turntable has a columnar section capable of fitting a disk-shaped medium and a circular supporting section capable of supporting the disk-shaped medium. A method of mounting the sub-frame on a motorcycle includes: fixedly securing a drop seat sub-frame portion onto a main frame portion, wherein the drop seat sub-frame portion is configured for receiving and securing thereon a drop seat. The anionic surfactant component is present in an amount at least as great as about 2% by weight. The scanner device also includes a display device that displays images in response to the metallurgical, nondestructive testing. The contactor further includes a fastening device arranged for mechanically and electrically connecting one of the output terminals to a corresponding input terminal of the coil, and the module is designed such that the fastening device connects the output terminal of the circuit board to the input terminal of the coil while at the same time the module is connected to the frame. The invention further relates to nutraceutical or dietary supplement composition comprising a physiologically acceptable salt of magnesium, quercetin, resveratrol, and hesperidin.
