A fuel vapor control device include a fuel tank for storing fuel, a canister for adsorbing fuel vapor produced in the fuel tank, and an evaporation path communicating between the fuel tank and the canister. The skill assessment tool of the preferred embodiment may include a large skill set of possibly-unrelated skills. In the present invention it is shown eleven cyclic peptides with different aminoacid sequences which inhibit the CKII phosphorylation in vitro, exhibit cytotoxicity on HPV-16 transformed cells and also increase the sensitivity of these cells to the cytostatic effect of interferon. This pattern is compared against current neural activity. In one example, the adjoining lateral surfaces are in abutting engagement with one another.
