Product R, a novel therapeutic composition for treating viral infections and stimulating the immune system, comprises a unique peptide having 31 amino acids and another unique peptide having 21 amino acids and connected with an oligo-nucleotide through a diphosphodiester or diphosphodithioate ester linkage. The leakage current is controlled by adjusting a switching speed of switches in the output inverter. The plurality of contacts of the card connector are arranged to correspond to respective plural external contact points of the SIM card. If the attempt to store-mark the cache line fails because a second thread holds a store-mark on the cache line, and if obtaining the store-mark will ensure forward progress for the first thread, the system forces the second thread to release the store-mark, so the first thread can acquire a store-mark for the cache line. The upper body is installed at its front surface with a display device. Furthermore, the porous layer of the hydrogen permeable material bonds to the solid layer, thereby greatly increasing the effective surface area of the solid layer that is exposed to hydrogen gas.
