Abstract: A solar power plant includes central receiver modules arranged in a regular pattern. Each central receiver module includes a tower, a central receiver mounted on the tower, and a heliostat array bounded by a polygon. The heliostat array includes heliostats with mirrors for reflecting sunlight to the central receiver. The heliostats are grouped in linear rows and each of the rows is parallel to another row. The locations of the heliostats are staggered between adjacent rows. The power plant also includes a power block for aggregating power from the central receivers and power conduits for transferring power from the central receivers to the power block.

Abstract: Loss of flow battery electrode catalyst layers during self-discharge or charge reversal may be prevented by establishing and maintaining a negative electrolyte imbalance during at least parts of a flow battery's operation. Negative imbalance may be established and/or maintained actively, passively or both. Actively establishing a negative imbalance may involve detecting an imbalance that is less negative than a desired threshold, and processing one or both electrolytes until the imbalance reaches a desired negative level. Negative imbalance may be effectively established and maintained passively within a cell by constructing a cell with a negative electrode chamber that is larger than the cell's positive electrode chamber, thereby providing a larger quantity of negative electrolyte for reaction with positive electrolyte.

Abstract: The invention relates to novel sulfolipids extracted from spirulins, to the process for obtaining them, to the compositions containing them and to their use as HIV-1 and HIV-2 inhibitors. The invention further relates to a spirulin biomass rich in sulfolipids which has an inhibitory activity towards HIV-1 and HIV-2 reverse transcriptase, and to the use of said sulfolipids, or of an extract of spirulin biomass rich in sulfolipids, for the preparation of a drug for the prophylactic or curative treatment of AIDS.

Abstract: A library stores individual component files of software distribution kits (SDKs) on a file storage server. When an SDK is to be added to the library, a file extractor copies component files from SDK volume master(s) and stores the copies in the library. The library includes a database to store information about the SDKs, such as how many SDK volumes are in each SDK and which component files are in each SDK volume. The database also stores the name and version of each SDK, thereby enabling a user to browse the library and select an SDK, or an individual SDK volume, for production. An SDK builder then creates the selected SDK volume(s). The SDK builder can “burn” CDs using, for example, a CD burner connected to the user's computer or a central, high-capacity robotic CD burner.
