摘要:
An internal combustion engine provided with a first port of a helical shape and second port of a straight shape opened to the combustion chamber. The first port provides a swirl motion in the cylinder, while the second port is opened to the combustion chamber at a position near the spark electrodes located at the upper portion of the combustion chamber in the center thereof. An intake control valve selectively opens or closes the second intake port in accordance with operating conditions of the engine. A main injector is arranged in the second port downstream of the intake control valve. The injector is so controlled that it opens substantially during the intake stroke when the intake control valve is closed. The injector is controlled to inject at the period substantially not located in the intake stroke.

When a camera server receives an instruction involving invalidation of viewing limitation (masking processing) of video from a privileged client, the camera server limits viewing of video data with respect to a general client and a recording client. The camera server stores the video data of a limited period in a secondary storage device. When the camera server receives an instruction involving validation of the viewing limitation from the privileged client, the camera server transmits the stored video data of the limiting period to the recording client.

Mobile nodes are allowed to move around within an intermittent communication environment. A mobile node wirelessly communicates with an access node when approaching the access node, and stores data. The access node stores an action history for each mobile node, and generates a forwarder list in association with a destination node, based on action histories of the mobile nodes. The forwarder list stores one or more identifies each identifying a first mobile node in the order of an arrival probability indicating a probability that the first mobile node succeeds in delivering the data to the destination node. The access node selects second mobile nodes that are to carry the data to the destination node, based on the forwarder list, and transfers the data to one of the second mobile nodes when a communication link is established between the access node and the one of the second mobile nodes.

Method and compositions for reducing the inflammation after cytokine exposure of an islet cell transplant without affecting the viability and potency are disclosed herein. The present invention describes a composition comprising Withaferin A (WA), a steroidal lactone derived from Withania somnifera to effectively block NF-kB activation in beta cells, minimize cytokine-induced cell death and improve survival of transplanted islets. The method of the present invention involves identifying a subject having islet cells in need of treatment; and providing a effective amount of a Withaferin A composition disposed in a pharmaceutically acceptable carrier in an amount sufficient to reduce the inflammation after cytokine exposure without affecting the viability and potency of the islet cell population.

摘要:
The present invention provides a solid electrolyte with high ion-conductivity which is cheap and exhibits high conductivity in an alkaline form, and stably keeps high conductivity because of a small amount of the leak of a compound bearing conductivity even in a wet state. The invention is useful in an electrochemical system using the solid electrolyte, such as a fuel cell.The solid electrolyte with high ion-conductivity comprises a hybrid compound which contains at least polyvinyl alcohol and a zirconic acid compound, and also a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine, obtained by hydrolyzing a zirconium salt or an oxyzirconium salt in a solution including water, polyvinyl alcohol, a zirconium salt or an oxyzirconium salt and a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine coexist, removing a solvent and contacting with alkali.

An electronic camera system includes a photographing ordering system and a photographing system. The photographing system includes an image sensor which photographs a subject and generates an image signal; a camera-side communication unit which communicates with the photographing ordering system; a subject judging unit which judges whether or not the subject is the person to be photographed based on the person identifying data when or after the subject is photographed; an image processing unit which generates the image data with the image signal; and a camera-side control unit which extracts the image data of which the person to be photographed has been photographed based on a judged result of the subject judging unit and transmits the extracted image data to the photographing ordering system.
摘要:
A metal oxide catalyst carrier particle has a center portion and an outer skin portion each containing a first metal oxide and a second metal oxide. The center portion and the outer skin portion are different in composition. The mole fraction of the metal of the first metal oxide is higher in the center portion than in the outer skin portion and the mole fraction of the metal of the second metal oxide is higher in the outer skin portion than in the center portion. The second metal oxide is selected from the group consisting of rare earth oxides, except for ceria, and alkali earth metal oxides. In addition, platinum is supported on the metal oxide catalyst carrier particle, thus forming an exhaust gas purification catalyst.

A fuel cell system of the invention includes a tubular switching member 70 with slits 70a to shift their position and thereby vary an opening area of outlets of oxidizing gas conduits 36 in respective unit fuel cells 30 constituting a fuel cell stack 20. The system further includes a drive roller 74 and a stepping motor 79 that function to change over the position of the slits 70a. An electronic control unit controls rotation of the stepping motor 79 to actuate the tubular switching member 70 first to narrow the opening area of the outlets of the oxidizing gas conduits 36 to or toward 0 and then to widen the opening area of the outlets of the oxidizing gas conduits 36, thereby generating pulsation in the oxidizing gas conduits 36. Water droplets flocculated in the oxidizing gas conduits 36 are thus discharged to the outlets with high efficiency. The structure of the embodiment does not require any bypass in the respective unit fuel cells 30. The characteristic structure of the invention uses the frame of the unit fuel cell 30 equivalent to the existing one and does not substantially increase the size of the fuel cell stack 20.
