A composition for increasing the bioavailability of oils in humans and animals comprising mixing a first emulsifier and a second emulsifier in a ratio ranging from about 1:1 to about 3:1 with a consumable oil wherein the first emulsifier is polyoxyethylene sorbitan monooleate and the second emulsifier is tocopheryl polyethylene glycol succinate. For this purpose the present invention provides a method for receiving signals by using a plurality of antennas that form a linear array antenna, multiplying a plurality of weight vectors by the received signals, summing the multiplication results for each weight vector, and combining the summing results by using maximum ratio combining. The method also includes terminating main etch step when a predefined etch depth of at least 70 percent of thickness into silicon layer is achieved. The control unit detects at least one series of consecutive unassigned sectors on the optical disc by referring to the read sector information.
