A method of restoring a lake that has a high saline level is disclosed herein. A graphical representation of the menu structure is generated and communicated to an on-line user. The thickness and crystallinity of the graphite layer can be freely controlled. The length of the cylinder and the width of the crown are of the range of one quarter of the average wavelength for which the antenna is dimensioned. Further, the signals in the ring oscillator are complementary to each other, so that by arranging these signals close to each other in a wiring, it is possible to realize low sensitivity to a mixed external signal. In further embodiments: the secondary handle is mounted to the top of the blade at a fixed angle of 45 degrees degrees between the long axis of the secondary handle and the long axis of the knife blade; and attachments are described to convert single handle knifes into double handle knives functioning identical to those described above.
