Identification of microorganisms, esp. Eisseria type -- pass through the chromogenic reaction with specific substrate and dyestuff

摘要

A building structure apparatus combining techniques for solar energy collection, heat storage and fresh air supply as an integral part of the actual structure, together with improved insulating value for the structure that makes possible the saving of energy also without solar radiation. Solar rays pass through an exterior covering layer (1), e.g., a glass plate, and air situated in an intermediate space (3) between said layer (1) and a heat absorbent/heat storing body (2) is heated, also by stored heat in the body (2) when the air is transported through the air-exposed body (2) with the aid of negative pressure in an inner building space (4). To improve the heat collection capability of the body (2), this may be provided with an air penetrable solar heat absorbent stratum (12) on the side facing the intermediate space (3) and an air penetrable insulating body (15) which is positioned between the heat storing body (2) and the building space (4). Utilization in buildings, vessels or installations associated with industry. The apparatus may be employed vertically or at a slant and may advantageously be combined with other energy saving techniques.
