Abstract: A method of making a data centre is disclosed, comprising making a data centre in an existing building (3010) having a floor, walls and a roof, an air inlet and an air outlet. The method includes: installing prefabricated data centre elements by (a) connecting to the inlet an air handling module (3001, 3002); and (b) installing cold aisle services modules (3011) each having one or more integrated blanking portions and one or more data centre services extending along its length terminating with a connection to an adjacent module (3011); and installing racks of IT equipment arranged in parallel rows; the method being so performed that the floor, racks, and cold aisle services modules (3011) together define parallel cold aisles for entraining cooling air flows to the IT equipment. Also disclosed are a data centre, a service carrying frame and a cold aisle services module for a data centre and a supporting frame for supporting prefabricated data centre elements.

Abstract: A method of cooling a data centre, and a data centre, is disclosed. Optionally, the data centre comprises: a cooling air source (201); at least one rack room (202) having a floor and rack storage areas (203a-203d) on the floor, each rack storage area accommodating racks in which items of electronic equipment having at least one fan (204) are housed; one or more cold aisles (205) in the rack room, each cold aisle being adjacent to a rack storage area; one or more hot aisles (206) in the rack room, each hot aisle being adjacent to a rack storage area; and an air supply corridor (207) for transporting cooling air, above the floor, from the cooling air source to the one or more cold aisles. The method optionally comprises transporting cooling air from the cooling air source (201) to the one or more cold aisles (205) substantially under the control of the fans (204) of the items of electronic equipment.

Abstract: Provided are nanoparticle-based vaccines that have an adjuvant coating attached to the external surface thereof to serve as an immunopotentiator. Most advantageously the nanoparticle vaccines have IgM antibodies attached to the external surface of an antigenic nanoparticle to serve as an immunopotentiator. The IgM may be attached by specifically binding to an epitope of the underlying nanoparticle including, but not limited to, the target vaccine immunogen. Since, however, the availability of specific IgMs is limited and less than the number of potential antigens that may be used as vaccines, attaching an IgM of the disclosure may require a hapten molecule that can be attached to the nanoparticle. By selecting a hapten that can be specifically recognized and bound by an IgM, it is possible to attach the hapten-specific IgM to a wide-variety of vaccine antigens.

Abstract: A method of providing cooling air for cooling data centre IT equipment, an evaporative humidifier and an air handling unit is disclosed. The method comprises operating an evaporative humidifier (201) to humidify air for supply as IT equipment cooling air, the evaporative humidifier preferably comprising a deformable wettable matrix (207). Preferably, the method comprises steps of wetting the deformable wettable matrix (207), passing air through the wetted matrix (207) thus producing humidified air, and expelling water from the wettable matrix (207) by subjecting the wettable matrix to compressive deformation.
