Abstract: A process for treating contaminated liquid, in which the liquid to be treated is contacted with a charged polymeric material and with a second, oppositely charged polymeric material. The polymeric materials are soluble in the liquid, and at least one of the soluble polymeric materials is a branched polymeric material. Floc formation is allowed and the flocs are separated from the liquid. The first and second polymeric materials may be selected from the group consisting of polysaccharides, proteins, lipids and polyhydroxy alcohols.

Abstract: A system and method are provided for implementing real-time antialiasing, transparency and motion blur of animated images displayed on a video monitor. Each pixel of an image to be displayed is associated with three attributes--a foreground color, a background color and a transparency factor. These attributes are used by a system processor to generate an index into a table of mixed colors that is stored in system memory. The table associates each combination of foreground color, background color and transparency factor with a color that appears to be a mixture of the foreground color and background color attributes for a pixel, with the weight of the mixture being defined by the transparency factor.

Abstract: A non-soluble particulate coloring material comprises dry ground red microalgae-derived material as the base coloring matter.

Abstract: A method of growing microalgae is described, which uses the outdoor sunlight as a source of energy. Growth is confined to an assembly of vertical, transparent tubes through which nutrient and air is carried with carbon dioxide. The microalgae is periodically harvested from the tubes.
