A method and apparatus are disclosed for transforming information from one semantic environment to another. The RF IC includes a VCO capable of switching oscillation frequency bands, a variable frequency divider, a phase comparator, and a loop filter, which are contained in the PLL loop. A plurality of transactions associated with the context is filtered using the contextual boundary parameters to obtain a pool of filtered transactions. The variable output of the electronic throttle control is in communication with at least the selected one of the electronic control modules. The cross-section of the elongated member, if divided into two parts, includes a generally triangular portion and a generally semi-circular portion which come together to form a teardrop-like shape. The catalysts are useful in hydrogenation and Fischer-Tropsch reactions.
