This invention relates to a vaccine and a method for immune activation which is effective for eliciting both a systemic, non-antigen specific immune response and a strong antigen-specific immune response in a mammal. The method is particularly effective for protecting a mammal from a disease including cancer, a disease associated with allergic inflammation, an infectious disease, or a condition associated with a deleterious activity of a self-antigen. Also disclosed are therapeutic compositions useful in such a method.

An internal combustion engine in which power is generated by burning a mixture of fuel supplied from a port injector and/or an in-cylinder injector and air in a combustion chamber, includes a valve drive mechanism which can change a valve opening characteristic of at least one of an intake valve and an exhaust valve; a turbocharger which supercharges air taken into the combustion chamber; a turbo motor which changes supercharging pressure generated by the turbocharger; a catalyst device including a catalyst which purifies exhaust gas discharged from the combustion chamber; and an ECU which controls the turbo motor such that pressure of the air taken into the combustion chamber becomes larger than back pressure until it is determined that the catalyst has been activated, and which sets a valve overlap period during which both of the intake valve and the exhaust valve are opened.

A shieldable needle device for shielding used needle cannulas. The device generally includes a hub housing and an elongated shield housing. A needle cannula having a distal puncture tip extends from the hub housing, with at least a portion of the needle cannula extending through the passageway of the shield housing. A biasing member acts on the shield housing to bias the shield housing from a first biased position adjacent the hub housing toward a second position covering the distal puncture tip of the needle cannula. An engagement mechanism extends dorsally from the hub housing and is in releasable engagement with a portion of the shield housing for releasably retaining the shield housing in the first biased position adjacent the hub housing. Activation of the engagement mechanism to shield the needle can be effectively accomplished during removal of the needle device from a patient, thereby providing for a passive activation of the device during normal use.

A device detects a wake-up keyword from a received speech signal of a user by using a wake-up keyword model, and transmits a wake-up keyword detection/non-detection signal and the received speech signal of the user to a speech recognition server. The speech recognition server performs a recognition process on the speech signal of the user by setting a speech recognition model according to the detection or non-detection of the wake-up keyword.

By incorporating carbon by means of ion implantation and a subsequent flash-based or laser-based anneal process, strained silicon/carbon material with tensile strain may be positioned in close proximity to the channel region, thereby enhancing the strain-inducing mechanism. The carbon implantation may be preceded by a pre-amorphization implantation, for instance on the basis of silicon. Moreover, by removing a spacer structure used for forming deep drain and source regions, the degree of lateral offset of the strained silicon/carbon material with respect to the gate electrode may be determined substantially independently from other process requirements. Moreover, an additional sidewall spacer used for forming metal silicide regions may be provided with reduced permittivity, thereby additionally contributing to an overall performance enhancement.

The invention provides enhancements to service discovery procedures associated with short-range communication in mobile terminals. In particular, the present invention employs a layered service discovery decision-making process that relies on historical information stored in the mobile terminal and mobile terminal analysis of the information associated with tag to make decisions regarding service discovery. As such, the present invention provides efficient service discovery that limits unnecessary connections to external servers and, thereby accelerates the overall service discovery process.

A process for forming a coordination catalyst system comprising sequentially or substantially simultaneously contacting: (I) pre-catalyst reactants comprising (a) at least one first ligand-containing reactant; and (b) at least one first transition metal reactant suitable to form at least one metallocene or constrained geometry pre-catalyst compound (e.g., rac-ethylene bis(indenyl)zirconiUm dichloride); an optionally (c) at least one second ligand-containing reactant and (d) at least one second transition metal reactant suitable to form at least one non-metallocene, non-constrained geometry, bidentate or tridentate transition metal compound (e.g., tridentate 2,6-diacetylpyridine-bis(2,4,6-trimethylanaline)FeCl₂) and (II) further contacting, jointly or individually, the pre-catalyst compound(s) and optional bidentate or tridentate compound(s) with at least one support-activator agglomerate (e.g., spray dried silica/clay agglomerate). When individually contacted, the supported catalyst components can be mixed or blended. The resulting transition metal catalyst systems are suitable for addition polymerization of unsaturated monomers, e.g., ethylene and propylene.

The invention provides an application method of cold field plasma discharge assisted high energy ball milled powder and a plasma assisted high energy ball milling device using the cold field plasma discharge assisted high energy ball milling method. The method comprises the following steps: utilizing dielectric barrier discharge to generate plasmas, introducing a dielectric barrier discharge electrode bar into a high-speed vibrating ball-milling tank, on one hand, requiring a solid insulating medium on the outer layer of the electrode bar to simultaneously bear high-voltage discharge and mechanical shock failure of the grinding ball, and on the other hand, requiring the high-speed vibrating ball milling device to uniformly process the powder. The method is based on the ordinary ball milling technology; the processing efficiency and the effect of the ball mill can be greatly improved by the following steps: under a non-heat-balance discharge condition of the pressure that the discharge space pressure is set to be about 102-106 Pa, introducing the discharge plasmas to input another effective energy to the processed powder, promoting the powder to be processed to be subjected to combined action of the mechanical stress effect and the heat effect of the external electric field, and further accelerating refining of the powder and promoting the alloying progress.

An antimicrobial polyolefin fiber sheet is provided wherein the polyolefin fiber sheet has one or more spots in which 1/100 or more by volume of individual inorganic antimicrobial agent particles are exposed on surfaces of polyolefin fibers per fiber sheet area of 1.0×10⁻² mm² or has one or more spots in which the inorganic antimicrobial agent particles are exposed on the surfaces of polyolefin fibers each occupying an area of 0.01 μm² or larger per fiber sheet area of 1.0×10⁻² mm². Such polyolefin fiber sheet is arranged as the core layer and this core layer is sandwiched between upper and lower layers of dry nonwoven fabric to form the mask filter in the form of a laminated sheet. Such mask filter is used to form the mask.

A method of co-producing activated carbon in a circulating, fluidized bed gasification process includes gasifying carbonaceous fuel in a fluidized bed to form syngas and char, activating the char to form particles of activated carbon, discharging syngas and particulate solids entrained with the syngas from the reactor, separating entrained solids from the syngas with a particle separator and returning at least a portion of the separated solids to the reaction chamber, but allowing a solids product, including activated carbon and having an average size smaller than a predetermined size, to exit the particle separator with the syngas. The solids product is separated from the syngas in a dust separator to form cleaned syngas, and both the cleaned syngas and the solids product are discharged from the gasifier.
