The present invention relates to compositions for use in refrigeration and air-conditioning systems comprising 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxybutane and at least one hydrocarbon. As a user provides or selects customized designs or themes, including color themes, font types, images, and the like, previews of one or more documents or templates to which the user selected designs or themes are applied are dynamically generated and are displayed to allow the user to select an actual document or template for use. The wireless communication device, through its communication using the conductor as an antenna, acts as an indicator of force to an interrogation reader when the wireless communication device is capable of communicating to the interrogation reader using the conductor as an antenna. A control portion changes a period of transmitting the code request signal in accordance with a situation of running the motorcycle to detect dropping of the smart key. This rate is determined to be optimum in hydrophilic solvent systems with an amine.
