Abstract: Transgenic eukaryotic (animal, plant and fungal) cells and organisms that contain decreased levels of saturated fatty acids are provided. The transgenic eukaryotic cells and organisms have been genetically engineered to contain and express heterologous prokaryotic enzymes with enhanced desaturase activity. Products made by or from the cells and organisms are also provided.

Abstract: The T-Post Sign Holder is comprised of a t-post receptacle and a sign support. The t-post receptacle is integrally formed to the sign support and the sign support is structurally reinforced onto the t-post receptacle via support webs. The use of the invention is relatively simple: the user slides the invention over the top of a t-post engaging the t-post into the t-post receptacle. The t-post receptacle is comprised of two internal channels into which the flanges of a standard t-post may engage. The user then mounts his sign onto the sign support using fasteners through a plurality of fastener holes formed by the sign support or using adhesive.

Abstract: The amino acid and nucleic acid sequences of a ?5-desaturase enzyme and a ?8-desaturase enzyme are disclosed. The nucleic acid sequences can be used to design recombinant DNA constructs and vectors. These vectors can then be used to transform various organisms, including for example, plants and yeast. The transformed organisms will then produce polyunsaturated fatty acids. The amino acid sequences are useful for generating enzyme-specific antibodies that are useful for identifying the desaturases.

Abstract: Processes and apparatus for treatment of flowing slurries of particulate material mixed in liquid employ a wide, elongated downwardly-slanted, metal tray with upturned edge flanges, cable-suspended for unrestrained vibratory flexing and undulation. The tray is provided with a plurality of ultrasonic transducers mounted on its underside, and the flowing slurry is delivered to the upper tray end, flowing lengthwise down the tray in a shallow flowing sheet. Ultrasonic vibratory energy coupled through the tray to the flowing slurry has a "microscopic scrubbing" action on all particles and agglomerates, breaking the surface tension on the particle, cleaning particle surfaces, and separating different constituent particles and coatings of gels, slimes, algae, clay or mud. Mixtures of fine particles of coal or other valuable minerals with ash, clay, rock or sand particles are separated with unexpected efficiency by these techniques.
