A golf ball having a cured polyurethane cover which includes an isocyanate group terminated polyurethane prepolymer comprising a specific alicyclic diisocyanate as a polyisocyanate component, and a specific 4,4\u2032-diaminodiphenylmethane derivative as a curing agent. The compounds have excellent effects of reducing blood lipid level, inhibiting cholesterol metabolism-related enzymes and preventing and treating blood lipid level-related diseases. If relatively flexible anti-ballistic materials are selected as components, the panels may be designed to collapse into rolls when not inflated. The update information identifies an update package for a respective application of the plurality of installed applications. The output node of the switch is connected to the output node of the first HBT via the output matching circuit, and an impedance looking into an output side of the radio frequency power amplifier from the output node of the switch is higher than an impedance looking into the output side of the radio frequency power amplifier from the output node of the first HBT. The method may include the steps of selecting a polymeric film, laser drilling at least one frustoconical pore in the film, depositing a layer of metal suitable for use as an electrode over a wall of the pore, and depositing a membrane capable of detecting an analyte in the pore over the metal layer.
