The present invention includes a control and analysis system, used in conjunction with a signal generation and detection apparatus, for capturing, processing and analyzing images of samples having resonance light scattering (RLS) particle labels. The control and analysis system processes instructions and algorithms for performing multiplexed assays of two or more colors, for example, to allow separation and analysis of detected light that contains information from two or more different types or sizes of RLS particles. The multiplexing analysis software is preferably incorporated within the system of the present invention, and the multiplexing analysis is preferably performed in real-time during a scanning or assay procedure. The invention provides for a computer readable medium containing instructions for carrying out the same.

A particulate filter regenerating device is configured to prevent the uneven distribution of particulate matter that results from interruption of the regeneration process and protect the particulate filter. The frequency with which regeneration is executed is increased by determining that it is time to regenerate the particulate filter at a time t1 when the exhaust gas temperature Texhin has reached or exceeded a prescribed temperature Texh1. Additionally, particulate filter regenerating device determines that it is time to regenerate the particulate filter when the quantity of accumulated particulate matter reaches or exceeds a prescribed value PM1. The particulate filter is regenerated by raising the temperature of the exhaust gas and combusting the accumulated particulate matter.

Recycling a portion of autothermal reformer effluent into the steam-hydrocarbon feed stream with a thermo-compressor ejector is disclosed, using the preheated feed mixture as motive fluid. Syngas recycle-motive fluid molar ratios are 0.2-1.0, selected to optimize the overall configuration. The recycle introduces hydrogen and steam into the feed, and elevates the feed temperature, for operating the reformer in a soot-free regime. There is some pressure drop between the raw feed steam-natural gas mixture and the reformer feed, which requires the raw feed mixture to be supplied at a higher pressure, but this is offset by the lower pressure drop in the process heater and other upstream and downstream equipment due to lower quantities of steam. The feed pre-heater can have a lower duty, and the upstream and downstream equipment can be reduced in size, while the size of the autothermal reformer is about the same compared to the size needed for operation without effluent recycle.

The invention relates to a method for removing impurities from an aqueous stream. The method includes directing the aqueous stream into an adsorbent contact zone and contacting the aqueous stream with an adsorbent material in the adsorbent contact zone so that impurities in the aqueous stream are adsorbed onto the adsorbent material. The aqueous stream and the adsorbent material is then directed to a ballasted flocculation zone where the adsorbent material is mixed with ballast to form sludge. The aqueous stream is then separated from the sludge to produce treated water and the sludge is settled in a settling zone. The ballast is then separated from the sludge and directed to the ballasted flocculation zone while the sludge and the adsorbent material are directed to a transition zone. In addition, the method requires measuring the concentration of the adsorbent material in the adsorbent contact zone and adding adsorbent material to the aqueous stream if the value of the measured concentration of the adsorbent material in the absorbent contact zone is below a predetermined threshold value.

Expression of a messenger RNA which encodes a protein which is expressed by differentiated cells, notably the cells of the skin or appendages thereof, is inhibited by topically administering to said differentiated cells a thus effective amount of at least one double-stranded RNA oligonucleotide, formulated into a topically applicable, physiologically acceptable medium therefor; such regime or regimen is useful for treating a variety of afflictions or conditions, e.g., combating the signs of skin aging, stimulating hair growth or retarding loss thereof, inhibiting cellular proliferation and/or differentiation, etc.

A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts.

A catalyst composition suitable for reacting hydrocarbons, e.g., conversion processes such as fluidized catalytic cracking (FCC) of hydrocarbons, comprises attrition resistant particulate having a high level (30-85%) of stabilized zeolites having a constraint index of 1 to 12. The stabilized zeolite is bound by a phosphorous compound, alumina and optional binders wherein the alumina added to make the catalyst is about 10% by weight or less and the molar ratio of phosphorous (P₂O₅) to total alumina is sufficient to obtain an attrition index of about 20 or less. The composition can be used as a catalyst per se or as additive catalyst to a conventional catalyst and is especially suitable for enhancing yields of light olefins, and particularly ethylene, produced during conversion processes.

A method for producing a fuel or fuel additive comprising providing a reaction mixture comprising oil and an alcohol in an oil-in-alcohol emulsion and a catalyst for converting the oil to the fuel or the fuel additive. The oil and the alcohol are reacted in the presence of the catalyst, at a concentration below that used in a conventional batch process, to produce the fuel or fuel additive. This low level of catalyst reduces the formation of diols and oxidation products that can diminish the quality of the fuel or fuel additive. The fuel or fuel additive produced is continuously removed during the reaction, effectively de-coupling the concentration of catalyst used from the rate of the two phase reaction.

An improved fuel air mixture apparatus which enhances the degree of mixing of fuel with air. The fuel-air mixture device includes a primary air passage having an inlet, an adjustable throttle and an outlet; a secondary air passage having an inlet and an outlet to the primary air passage between its adjustable throttle and its outlet; a nozzle having an orifice opening into the secondary air passage for introducing a flow of fuel therein; a needle arranged co-axially of the nozzle with its small diameter at least normally extending from the orifice into the secondary air passage, the needle being axially moveable to provide variability of the orifice and control of the fuel flow; a control device for directly linking or controlling the position of the needle to the position of the adjustable throttle in the primary air passage for adjustment of the orifice of the nozzle. The arrangement is such that the fuel flow from the nozzle is matched to the position of the adjustable throttle and the fuel flowing from the orifice towards the small diameter end of the needle mixes with air flowing through the secondary passage prior to mixing with the air flowing through the primary air passage.
