The present invention is a method and apparatus to assist a user in optimizing a relationship with a contact person. A logout strategy is provided to include a set of security levels of varying sensitivity, with each security level having a set of permissions associated therewith and that are enforced upon occurrence of an event. A section of the carbon nanotube is removed to form at least one exposed end defining a first gap. Thus, the injected reaction gas is dissolved, and a large number of ultra-fine particles are produced. After deposition of an a-Si or polysilicon layer in a trench formed in a semiconductor, the a-Si or polysilicon is exposed to hydrogen at an elevated temperature.
