A method and system of providing access privileges to records of members of a community may comprise storing an assignment of a member of a community to a first position in the community to generate a first relationship. The invention also concerns a method for increasing and enhancing the taste of flavours and other factors of taste present in domestic animal foods. A movable portion 28 on the free end side is a lightweight coupling member 19 provided by bend-processing an aluminum thin plate, to which a rare-earth magnet 25 is adhered. 01 to 50 percent by weight; a metal chelating agent, from approximate 0 to 10 percent by weight; and a compound for lowering a surface tension of the combination of water, hydrogen peroxide, pH buffering agent, and metal chelating agent. A motor reciprocally rotates the sonotrode relative to the support assembly, thereby moving the flanges relative one another to generate frictional heat and create a friction weld therebetween.
