Abstract: The heat output, e.g., megawatt product or steam generation, of a combustor is increased, preferably while plume is mitigated, by targeting treatment chemicals to locations in a furnace. The process improves heat output from the fuel in the region of the combustor optimum for heat recovery and also maintains good heat transfer characteristics for the heat exchange surfaces. The effectiveness of targeted in furnace injection, in-fuel introduction and in-furnace introduction of slag and/or corrosion and/or plume control chemicals are preferably determined, as are the effectiveness of targeted in furnace injection, in fuel introduction and in furnace introduction of combustion catalysts. Then, the effectiveness of various combinations of the above treatments are determined, and a treatment regimen employing one or more of the above treatments is selected. Preferred treatment regimens will contain at least two and preferably three of the treatments.

Abstract: A corrosion control process is described. The process is especially useful in the control of chloride corrosion in waste to energy boilers. Corrosion of high temperature surfaces can be assessed by the monitor and controlled introduction of treatment chemicals by targeted in furnace injection reduces corrosion while maximizing combustion efficiency. A corrosion monitor is also described. Before and following selection of corrosion control chemicals and the locations for targeted in furnace injection, injection regimen and chemical selection and introduction parameters are monitored with the aid of the method and apparatus of the invention to adjust one or more control parameters to reduce corrosion. A preferred method will employ a treatment chemical that comprises an SO2 or SO3 reagent, e.g., sulfuric acid, sulfur, a sulfate salt or a bisulfite salt.

Abstract: The invention relates to factor D inhibitors, which bind to factor D and block the functional activity of factor D in complement activation. The inhibitors include antibody molecules, as well as homologues, analogues and modified or derived forms thereof, including immunoglobulin fragments like Fab, F(ab?)2 and Fv, small molecules, including peptides, oligonucleotides, peptidomimetics and organic compounds. A monoclonal antibody which bound to factor D and blocked its ability to activate complement was generated and designated 166-32. The hybridoma producing this antibody was deposited at the American Type Culture Collection, 10801 University Blvd., Manassas, Va. 20110-2209, under Accession Number HB-12476.

Abstract: The present invention provides methods for the directed differentiation of embryonic stem cells along the endodermal lineage, especially the pancreatic lineage.

Abstract: NOx and SO3 emissions from combustion of a sulfur containing carbonaceous fuel are reduced simultaneously. The combustion gases comprising NOx and SO2 are mixed with a NOx control agent into the combustion gases at a point upstream of a selective catalytic reduction catalyst for reduction of NOx. Following an SCR catalyst or other equipment that can oxidize SO2 to SO3 and prior to contact with an air heater for heating incoming combustion air, magnesium hydroxide is introduced in amounts and with droplet sizes and concentrations effective to form nano-sized particles in the effluent and reduce SO3 caused by the oxidation of SO2 in the catalyst. Computational fluid dynamics is employed to determine flow rates and select reagent introduction rates, reagent introduction location(s), reagent concentration, reagent droplet size and/or reagent momentum.

Abstract: A preferred apparatus arrangement utilizes the enthalpy of the flue gas, which can be supplemented if need be, to convert urea (30) into ammonia for SCR. Urea (30), which decomposes at temperatures above 140.degree. C., is injected (32) into a flue gas stream split off (28) after a heat exchanger (22), such as a primary superheater or an economizer. Ideally, the side stream would gasify the urea without need for further heating; but, when heat is required it is far less than would be needed to heat either the entire effluent (23) or the urea (30). This side stream, typically less than 3% of the flue gas, provides the required temperature and residence time for complete decomposition of urea (30). A cyclonic separator can be used to remove particulates and completely mix the reagent and flue gas. This stream can then be directed to an injection grid (37) ahead of SCR using a blower (36).

Abstract: A tongue stabilizer includes a tongue-engaging plate that is held on a laryngoscope blade by pressure sensitive adhesive, with a foam strip in-between to compensate for any irregularities between the tongue-engaging plate and the laryngoscope blade. The tongue-engaging plate is cup shape to cradle the tongue to prevent the tongue from interfering with the visibility and process of intubation. A protective strip can be used to cover the adhesive.

Abstract: This invention relates to novel human organic anion transporter polypeptides and genes encoding such polypeptides. The invention is directed towards the isolation, characterization and use of human organic anion transporter polypeptides for pharmacological screening of substrates, analogues of substrates, and modulators of human organic anion proteins. This invention also provides cell cultures, which stably contain nucleic acid sequences encoding human organic anion transport polypeptides. Such cell lines are useful for screening compounds in vitro to identify and characterize modulators, inhibitors and substrates of human organic anion transporter polypeptides.

Abstract: To elucidate molecular mechanisms in learning and memory, the expression of mRNAs in brains of rabbitsundergoing eyeblink conditioning was analyzed. Infusion of the transcription inhibitor actinomycin D (ActD) into the cerebellar nuclei reversibly blocked learning but not performance of the CR. Differential display PCR (DD-PCR) analysis of cerebellar RNAs from trained and pseudo-trained rabbits identified a 207-bp band that was induced with learning. The fragment was used to isolate a cDNA from a &lgr;gt11 rabbit brain library containing a 1698-bp open-reading frame. The genomic sequence also has been obtained and is reported. The deduced amino acid sequence contains the KKIAMRE motif, which is conserved among cdc2-related kinases. These results suggest that there is a new category of cdc2-related kinases in the brain whose function may be important in learning and memory.
