Abstract: Methods and systems provide the automatic tracking of the physical location of information technology components in a data center. These systems automatically identify where a given IT component, such as a server, router, switch or other device, is located. They automatically identify which slot the IT component is located in a given rack in the data center. When a server is added or removed from a particular slot, the tracking database is automatically notified and updated, and users of the database have instantaneously accurate information about the location of each IT component in a data center. If the server is changed to a different slot or rack, the system immediately identifies that the given server or device is located in a different location. Users can rely on the information in the database when remotely managing the data center's IT assets.

Abstract: A heat exchanger (10?) for the air supply circuit of a motor vehicle engine, comprises a heat exchange core (100) and at least one header tank (210?). The heat exchanger (10?) comprises an air flow rate control valve (300) arranged in the header tank (210?) of the exchanger, and the control valve (300) is a valve comprising a body (310) with three openings (311; 313) and a moving rotary member (320) inside the body (310) so as to control the circulation of air through the heat exchange core (100) and/or through a duct (13?) bypassing the heat exchange core (100) according to a law defined as a function of the angular position of the rotary member (320) in the body (310). The heat exchanger (10?) is particularly applicable to motor vehicles with a supercharged engine.

Abstract: The construction of a mutant in the phoP gene by means of homologous recombination from a clinically isolated Mycobacterium tuberculosis reduces the virulence thereof in mouse bone marrow macrophage. Moreover, the phoP mutant reduces the virulence thereof in the experimental mouse model. Said phoP mutant can persist without being eliminated both in the macrophage and in the mouse. Mice inoculated with the phoP mutant are protected against M. tuberculosis infection. The use of mutants of mycobacteria in which the phoP gene or the genes regulated by phoP have been inactivated are candidates for vaccines against human and animal tuberculosis as well as possible recombinant vaccines against other pathogens.
