Abstract: The invention provides compositions and methods for modulating GDP-L-Galactose Guanyltransferase (also known as GDP-L-Galactose phosphorylase) activity; and/or GDP-D-Mannose epimerase activity; and/or ascorbate content in plants. The invention provides plants and plant cells with increased GDP-L-Galactose Guanyltransferase activity; and/or GDP-D-Mannose epimerase activity. The invention provides plants and plant cells with increased ascorbate content as a result of: over-expression of GDP-L-Galactose Guanyltransferase; over-expression of GDP-D-Mannose epimerase; or in particular over-expression of a combination of GDP-L-Galactose Guanyltransferase and GDP-D-Mannose epimerase.

Abstract: The described systems and methods are directed at configuring a server based on a selected role. An installation application is configured to install core components in a server where these core components enable the server to perform the basic functions of a network computing device. A role management application is configured to enable a system administrator to select a role for the server and to automatically determine software components associated with the selected role. The role management application is then configured to build the software components and install the components on the server. The role management application is further configured to configure the components for the selected role. The automated installation process performed by the role management application enables a server to be efficiently configured for a particular role without installing other unnecessary components unrelated to the role.

Abstract: A portable audio player stores a large amount of compressed audio data on an internal disk drive, and loads a portion of this into an internal random access memory (RAM) which requires less power and less time to access. The audio player plays the data stored in RAM and monitors the amount of unplayed data. When the amount of unplayed data falls below a threshold, additional data is copied from the disk drive into RAM. Because the time necessary to copy a block of data from the disk drive to RAM is much less than the amount of time it takes to play the same block of audio data from RAM, this approach minimizes the amount of time that the disk drive must be operated, and thus minimizes the amount of power consumed by the system.
