摘要:
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit; injects an ozone-containing gas into the portion to provide an ozonated portion; recombines the ozonated portion with the flow of water in the conduit; and regulates the diverted portion to provide a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.

摘要:
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit, injects ozone into the portion to provide an ozonated portion, and recombines the ozonated portion with the flow of water in the conduit. Another method and system identifies a species-destructive reaction product of ozone with a water constituent, determines a life of the reaction product, and contacts ozone with a water containing the species for a period determined according to the determined life of the reaction product.

A target biokill of species for water to be discharged from a ballast tank of a sea faring vessel is determined. A diverted portion of sea water is regulated prior to charging the water into the ballast tank. Regulation of the diverted portion of water and a rate of injection of the ozone into the portion are adjusted to attain the target biokill. Then ozone at the determined rate into the regulated diverted portion to attain the target biokill when the portion is recombined into the water for charging to the ballast tank.

A miniature electret microphone includes a housing, a back plate/diaphragm assembly, an integrated circuit and a filter circuit. The housing for the microphone includes a sound inlet port. The back plate/diaphragm assembly is disposed within the housing and the assembly has an output responsive to sound pressure incident on the diaphragm. The integrated circuit includes a floating ground substrate and a p-n junction disposed within the housing coupled to the output. The filter circuit is formed within the integrated circuit, the filter circuit including a capacitor formed by the p-n junction.

A method and apparatus for detecting split brain in a distributed system is provided. After determining that a rogue instance is no longer an active member of the cluster, a recovery instance detects activity associated with a redo log that is updated by the rogue instance to store log records that describe changes made by the rogue instance to data associated with the cluster.

The present invention is an encapsulated sensor suite that deploys remotely. After deployment, an imager in the sensor suite is raised by a variety of means and is capable of being turned by a motor that locks on to sounds coming from a potential target. The motor is actuated by three microphones that when used in concert, point the imager to the direction of the sound's origination. The imager is also activated by a seismic detector which is deployed at the base of the encapsulation. The encapsulation may be righted by soft to hard metal contacts that release the hard metal with sufficient force to flip the sensor to the correct side for deployment.

An exercising device includes a disc shaped member capable of rotating about a point of rotation. The exercising device also includes an elongated supporting member connected to the point of rotation of the disc shaped member. Further, the exercising device includes a braking mechanism carried by the elongated supporting member. The braking mechanism is capable of contacting the disc shaped member to apply a resistance to the rotation of the disc shaped member. Moreover, the exercising device includes a foot engaging member connected to the disc shaped member. The foot engaging member is adapted to be operated by feet of an individual. The operation of the foot engaging member by the individual against the resistance to the rotation applied by the braking mechanism exercises the individual.
摘要:
The invention provides a new stringent starvation protein Salmonella sspA promoter and expression system suitable for expression of heterologous nucleic acids and proteins. The invention also relates to the use of an expression construct comprising either a Salmonella or an E. coli sspA promoter, or a bacterium into which the construct has been introduced, and their use in a pharmaceutical composition. The pharmaceutical composition is suitable for use as an immunotherapeutic composition and in particular, a vaccine delivery system. The expression vector is capable of being maintained extra-chromosomally or by integration into a bacterial host genome, whereby proteins may be expressed.
