    摘要： The system and method spatially predict the condensation of water and acid from the flue gas in the condensing heat exchanger installed in fossil power plant flue gas treatment system or similar environment. By modifying the operational conditions, the heat exchanger can control rates and areas of condensations. The system and method adjust either the cooling water temperature or the flowrate ratio of flue gas to cooling water to control the condensation rates of water or acids. The system and method also estimate actual coverage areas to apply for anti-corrosive coating onto the tube or duct surfaces to resist corrosion due to acid condensation. The system and method also optimize or customize condensation rates of water and acids in boiler flue gas under operating conditions given at a power plant.

    摘要： Ascorbate protects tissues against damage caused by reactive oxygen species (ROS) produced through normal metabolism or generated from stress. The inositol route to AsA involves four enzymes: myo-inositol oxygenase, glucuronate reductase, gluconolactonase (GNL), and L-gulono-1,4-lactone oxidase (GulLO). Eighteen putative GNLs were identified in Arabidopsis, one of which, AtGNL, is interesting because it possesses a chloroplastic signal peptide. Knockouts on this gene had lower foliar AsA and stunted growth compared to controls. The functional gene restored the phenotype of the knockouts, and those plants had higher AsA content, enhanced photosynthetic capacity, and higher seed yield.

    摘要： The system effectively manipulates the operation of a charged particle flow device by approximating the total force on each ion during a trajectory calculation. The system applies the method in massively parallel general-purpose computing with GPU (GPGPU) to test its performance in simulations with thousands to over a million ions. The method calculates the forces on an ion using ions within an active region near the ion of interest. To decrease computation time, the method approximates the forces by calculating the ion-ion interactions within a first zone and the ion-ion cloud interactions within a second zone. The system adjusts settings of the charged particle flow device to affect the flow and positioning of the charged particles. Such setting may include adjusting the positioning of the charged plates, adjusting the voltage of the plates, and adjusting the pressure within the charged particle flow device.

    摘要： A method or process to increase the production of products of interest in plant material including plant cultures, such as, for example, cell suspension cultures, root cultures, and hairy root cultures is provided. In one embodiment, the method is to contacting the plant material with a precursor or xenobiotic when producing a product of interest from a plant. In another embodiment the plant material is also contacted with a trapping agent. The process may also provide for contacting an elicitor of the product of interest with the plant material. An embodiment provides for contacting an elicitor, precursor and trapping agent with the plant material. The ability to produce novel compounds such as glucosides and glucuronides is provided.

    摘要： The process and system led to the identification of prenyltransferase genes from elicitor-treated peanut hairy roots. One of the prenyltransferases, AhR4DT-1 catalyzes a key reaction involved in the biosynthesis of prenylated stilbenoids, in which resveratrol is prenylated at its C-4 position to form arachidin-2, while another, AhR3′DT-1, was able to add the prenyl group to C-3′ of resveratrol. Each of these prenyltransferases has a high specificity for stilbenoid substrates, and their subcellular location in the plastid was confirmed by fluorescence microscopy. Structure analysis of the prenylated stilbenoids suggest that these two prenyltransferase activities represent the first committed steps in the biosynthesis of a large number of prenylated stilbenoids and their derivatives in peanut.
