摘要:
A gasoline engine having an exhaust system comprises means for trapping particulate matter (PM) from the exhaust gas and a catalyst for catalysing the oxidation of the PM by carbon dioxide and/or water in the exhaust gas, which catalyst comprising a supported alkali metal. The invention further includes a method of combusting PM from a gasoline engine in CO2 and/or H2O from the exhaust gas at temperatures in excess of 500 ° C., which method comprising trapping the PM and contacting it with a catalyst comprising a supported alkali metal.

A system for converting propelling thrust to produce a continuous flow is provided. The system can be integrated and/or retrofitted to the body of an aircraft. The system includes a pressure-lowering device and a sample chamber. The pressure-lowering device is used produce a low-pressure, continuous flow from a high-velocity propelling thrust source. Moreover, the pressure-lowering device is a passive flow generator that does not require a power source in order to produce a continuous flow from a propelling thrust. The design of the pressure-lowering device produces a flow rate that is independent of the aircraft motion. The sample chamber is used to measure and analyze ambient gases which are pulled through the sample chamber by the pressure-lowering device, as a result of the high-velocity air stream produced by the propelling thrust source.

Embodiments of the invention relate to generating security permissions for applications. A static analysis on an application is carried out to determine security exceptions and to determine the application components responsible for the security exceptions. The determined security exceptions are analyzed to calculate permissions required for each component. A security policy file that includes a hierarchy of the required permissions suitable for the type of application is formatted and applied to the application to provide a security enabled application.

A request for a navigated content associated with a browsing session can be received. The navigated content can be an electronic artifact which can be presented within an interface during the browsing session. The navigated content can be associated with a data source. The interface can be associated with a computing device. A usage metric associated with the navigated content can be collected. The usage metric can be a frequency and/or a duration measurement. The usage metric can be determined to be equivalent to a threshold value of a usage ruleset and can automatically persist within an offline cache the navigated content. A non-navigated content within the offline cache can be programmatically stored. The non-navigated content can be an electronic artifact linked to the navigated content wherein the non-navigated content is not presented within the interface during the browsing session.

Polyolefin fibers and filaments, and fabrics made therefrom, are rendered dyeable via a combination of dyeability additives. The dyeability additive combination comprises at least one compound selected from the group consisting of the polyamides, copolyamides and polyetherpolyamides and at least one ethylene vinyl acetate. The dyed polyolefin fibers and fabrics are rendered light stable via the use of a combination of stabilizers, which comprises at least one compound selected from the group consisting of the ultraviolet light stabilizers and at least one compound selected from the group consisting of the hindered amine light stabilizers. The ultraviolet light stabilizers are for example hydroxyphenylbenzotriazoles or tris-aryl-s-triazines. The hindered amine light stabilizers are for example of high molecular weight, for instance greater than 1000 g/mol. The dyes are for example anthraquinone blue dyes, anthraquinone red dyes, diazo red dyes or nitro yellow dyes.
