  • Publication number: 20180161415
    Abstract: Viruses, and particularly genetically engineered, replication deficient viruses such as adenoviruses, poxviruses, MVA viruses, and baculoviruses which encode one or more antigens of interest, such as TB, malarial, and HIV antigens, are spray dried with a mannitol-cyclodextrin-trehalose-dextran (MCTD) to form a powder where the viability of the viruses are maintained at a suitable level for mass vaccinations after spray drying, and where the viability of the viruses are maintained at suitable level over a period of storage time, even in the presence of humidity.

  • Publication number: 20040151336
    Abstract: A handheld device having an auto-volume control means for earphone plugging and the controlling method thereof is provided. A first preset volume value and a second preset volume value are set by a user to adjust the volume of an earphone and a speaker separately. Since output volume to the earphone and the speaker is under separate control, there is no need to readjust volume when the earphone is plugged in or unplugged. In addition, an over-volume protection and earphone volume micro-adjustment function are also incorporated to improve operation.
