Methods for fabricating a CMOS structure use a first gate stack located over a first orientation region of a semiconductor substrate. A single device may be used to both stabilize and fasten the two pieces of tissue, or a separate stabilizing device may be used in conjunction with a fastening device. The fiber reduces the differential mode delay among modes. Nucleic acids encoding the enoyl reductases, the enoyl reductases, and anitbodies for the enoyl reductases are also included. In this manner, an inexpensive and accurate measuring mechanism is provided for measuring the temperature.
