A composition comprising an albumin-based colloid and its use in treating hypovolemic conditions such as capillary leak syndrome and shock are disclosed. The system has a heat source located at a position that is spaced from the mirror, a control system that controls the operation of the heat source, a working fluid that is heated by the heat source and used to transfer heat from the source to the mirror, and a delivery system that constrains the heated working fluid and delivers it from the heat source to the mirror. 10 \u03bcm or above, and the value obtained by dividing the thickness of the tin layer 3b by the thickness of the copper layer 3a is 0. The shielding cover is heat-conductive and electrically-conductive material, and defines a cavity therein. Further, an off the record mode may be selectively enabled by the user to preclude remote users from recording the communications being transmitted during a chat session. The platform section has a frame attached to the extension members and a padded member on top of the frame.
