Abstract: A method and system for an improved online auction is provided. The improved online auction fosters a win-win scenario and a sense of fairness between buyers and sellers, whereby the participants know the exact dollar cost to complete the auction process within a predictable timeframe. Auction participants know the entirety of their monetary investment in completing an auction—a registration fee. The present invention is adapted so that such participants can earn bidding units as a function of their skill in playing online games with other participants. Wherein, bidding units are used to buy the auctioned item, thereby fostering a non-dollar based competitive nature that attracts some users to auctions, yet maintaining a sense of level-field fairness so as to not repel other users.

Abstract: The present invention consists in the design of an ELISA test, specific to determine through fecal feces, urine or plasma of birds, reptiles and mammals, the levels of concentration of the hormone testosterone as an indicator of masculine sex in these species for a better handling of the reproduction and the production of birds, reptiles and mammals. The procedure can be applied for practical purposes in any commercial operation that involves these species. With this method a greater efficiency and economic return is obtained, which reports improvement and greater benefits to the producers.
