Abstract: Provided are recombinant constructs comprising DNA sequences encoding enzymes effective in altering the biosynthesis and accumulation of sterol compounds and tocopherols in transgenic plants. Also provided are methods of using such constructs to produce transgenic plants, seeds of which contain elevated levels of sitostanol and/or sitostanol esters, and ?-tocopherol, as well as reduced levels of campesterol and campestanol and their corresponding esters. These seeds also contain the novel sterol brassicastanol. Oil obtained from seeds of such transgenic plants is also provided. This oil can be used to prepare food and pharmaceutical compositions effective in lowering the level of low density lipoprotein cholesterol in blood serum. In addition, novel DNA sequences encoding plant steroid 5?-reductases are also disclosed.

Abstract: An electrokinetic pump for pumping a liquid includes a pumping body having a plurality of narrow, short and straight pore apertures for channeling the liquid through the body. A pair of electrodes for applying a voltage differential are formed on opposing surfaces of the pumping body at opposite ends of the pore apertures. The pumping body is formed on a support structure to maintain a mechanical integrity of the pumping body. The pump can be fabricated using conventional semiconductor processing steps. The pores are preferably formed using plasma etching. The structure is oxidized to insulate the structure and also narrow the pores. A support structure is formed by etching a substrate and removing an interface oxide layer. Electrodes are formed to apply a voltage potential across the pumping body. Another method of fabricating an electrokinetic pump includes providing etch stop alignment marks so that the etch step self-terminates.

Abstract: Described is a process to synthesize nano-size Zeolite A from an amorphous gel precursor which can be synthesized via reaction of NaAlO2, NaOH, and tetraethoxysilane (TEOS). Zeolite A with particle sizes of ˜150 nm was made by transformation of the amorphous precursor in (CH3)4NOH solution with Zeolite A seeding. The nano-sized Zeolite A can be part of processes for making non-phosphate detergent where the as-synthesized Zeolite A used as builders, for making thin films for separation and/or catalysis, for making secondary ordered patterns.

Abstract: The method of the present invention involves first estimating the common gamut of the colors that this printer is expected to reproduce. Two color test targets are defined, each containing a wide range of color patches spanning color space. Preferably comprising color patches which are expected to be outside the gamut of the printer as well as color patches expected to be within the gamut of the printer. The left-to-right test target is printed in single-pass, uni-directional print mode, (printing on left-to-right scans only) and a color calibration table for left-to-right printing is generated. The right-to-left test target is printed in single-pass, unidirectional print mode, (printing on right-to-left scans only) and a color calibration table specific for right-to-left printing is generated. The next step of the present invention involves determining the mathematical intersection of the gamuts produced by printing in left-to-right mode only and by printing in right-to-left mode only.

Abstract: A computer-aided method for deigning and producing an online course is described. An electronic online course structure is generated using one or more clusters of learning objects corresponding to learning molecules. Each learning molecule defines a course topic around which a learning experience is organized. An XML course structure document is generated from an electronic online course overview. During an initial phase of development, one or more directories of placeholder course web pages are automatically generated to mirror the course structure defined in the course structure document. Each placeholder course web page corresponds to one of the learning objects associated with each learning molecule. During a second phase of development, course content is produced for each learning object, and learning objects are embedded into the placeholder web pages. Web page properties are defined for each course web page.

Abstract: A liquid cooling system utilizing minimal size and volume enclosures, air pockets, compressible objects, and flexible objects is provided to protect against expansion of water-based solutions when frozen. In such a system, pipes, pumps, and heat exchangers are designed to prevent cracking of their enclosures and chambers. Also described are methods of preventing cracking in a liquid cooling system. In all these cases, the system must be designed to tolerate expansion when water is frozen.

Abstract: An automatic wafer loading and pre-alignment system for integrated circuit wafer-mask Aligners. A belt feed track system is employed to transport wafers from a "send" wafer storage carrier to a wafer pre-alignment station. The wafer is machanically pre-aligned with respect to the wafer chuck of the Aligner by means of a roller arm and flat-finder system. After completion of the pre-alignment process, the Aligner turntable is rotated to carry the pre-aligned wafer and chuck to the home position of the turntable and at the same time position another chuck at the pre-alignment station. If the new chuck at the pre-alignment station contains a wafer, the wafer is transported from the chuck to a "receive" wafer storage carrier by means of a belt return track system. The feed and return wafer belt track systems have a common portion between the pre-alignment station and the respective "send" and "receive" wafer storage carriers.
