An electronic apparatus is provided with an electric part which can be attached to an outer wall of the apparatus body. An expansive horizontal structure parallel to the surface of the water confines one or more horizontal layers of water, a distributed array of heat transfer structures gathers solar energy and imparts it to the confined water, and one or more heat engines produce electricity utilizing the temperature differential between the confined water and ambient water. An elevated compartment lip engages a lid interior over the lip to seal the cards from wind and water. Upon subsequent receipt of that identification tag, the receiving computer streams the video segment to a destination computer on the network. By appropriately maneuvering each member and applying radiofrequency energy between the proximal and distal ends of the occlusion, a continuous channel is created. Specifically, in one embodiment it relates to utilizing Lng105 to determine the risk of lung cancer.
