A method for providing 11C-labeled cyanides from 11C labeled oxides in a target gas stream retrieved from an irradiated high pressure gaseous target containing O2, wherein 11C labeled oxides are reduced with H2 in the presence of a nickel catalyst under a pressure and a temperature sufficient to form a product stream comprising at least about 95% 11CH4, the 11CH4 is then combined with an excess of NH3 in a carrier/reaction stream flowing at an accelerated velocity and the combined 11CH4 carrier/reaction stream is then contacted with a platinum (Pt) catalyst particulate supported on a substantially-chemically-nonreactive heat-stable support at a temperature of at least about 900° C., whereby a product stream comprising at least about 60% H11CN is provided in less than 10 minutes from retrieval of the 11C labeled oxide.

An internal antenna module and a wireless communication apparatus having the same are disclosed. The internal antenna module includes a carrier having a partition formed on a surface thereof and a space defined by the partition; and a radiator disposed on the partition of the carrier. The space is formed in a region of the surface of the carrier excluding a region required to support the radiator. Therefore, influence of the carrier is minimized so that the radiation performance may be improved.

Provided is a method of inhibiting the formation of coke in an ethylene dichloride to vinyl chloride monomer pyrolysis cracker. The coke formation, which occurs during an ethylene dichloride pyrolysis reaction, is inhibited by contacting a heat-transfer surface of the cracker and a boron compound. The amount of coke generated when a coke formation-inhibiting material is used is 50% or less of that when a coke formation-inhibiting material is not used. In this case, however, the ethylene chloride conversion and the selectivity to a vinyl chloride monomer during the pyrolysis reaction are not affected. Accordingly, the efficiency of the pyrolysis cracker can be maximized.

The present invention relates to a portable terminal, and to a method and apparatus for improving broadcasting reception performance of the portable terminal by filtering a transmission frequency of a radio frequency unit introduced to a broadcasting reception path without experiencing broadcast signal loss. The filtering can be achieved using a filter that includes a variable capacitor in the broadcasting reception path. Accordingly, the transmission frequency of the radio frequency unit may be filtered without a broadcast signal loss. A capacitance of the variable capacitor may be controlled according to the broadcast channel.
