摘要:
An exemplary heat dissipation device includes a fin assembly, a heat pipe, and a protective member. The fin assembly includes stacked fins and air passages between fins. Each fin includes a main body, an extending hole defined in the main body, and a flange extending from the main body around the extending hole. The heat pipe is received in the extending holes of the fins and abuts the flanges of the fins. The protective member includes a plurality pairs of elastic arms. Each pair of elastic arms is sandwiched between a free end of the flange of a corresponding fin and the main body of a corresponding adjacent fin to prevent solder associated with the heat pipe from flowing into the corresponding air passage.

Operation of a spark ignition, direct injection engine having an aftertreatment system including an oxidation catalyst and a selective catalyst reduction device is described. The method includes controlling to a stoichiometric air/fuel ratio and retarding spark ignition timing. Engine fueling is then controlled to a lean air/fuel ratio and spark is retarded. The engine is then operated to generate ammonia reductant. Engine operation then comprises operating at a preferred air/fuel ratio and controlling spark ignition timing to a preferred timing.

In accordance with embodiments, there are provided mechanisms and methods for the transient storage of user interface configurations. These mechanisms and methods for the transient storage of user interface configurations can provide accessibility of user interface configurations prior to such user interface configurations being saved by the respective author. The ability to provide accessibility of user interface configurations prior to such user interface configurations being saved by the respective author can enable the user interface configurations to be used in many different ways even before they are saved, such as enabling the re-use of a user interface configuration across multiple different user interfaces, enabling multiple different users to apply further configurations to the user interface, enabling future access to the user interface configuration, etc.

Compositions having a combination of specific biological components have been found to exert a number of useful effects in mammalian cells, including modulating TGF β signaling, apoptosis, and proliferation of mammalian cells, as well as decreasing inflammation in mice. These components can be obtained commercially, or can be prepared from biological tissues such as placental tissues. Placental amniotic membrane (AM) preparations described herein include AM pieces, AM extracts, AM jelly, AM stroma, and mixtures of these compositions with additional components. The compositions can be used to treat various diseases, such as wound healing, inflammation and angiogenesis-related diseases.

An exhaust aftertreatment system that includes a suitable combination of particulate catalyst materials is used to effectively reduce an amount of NOX to N2 and water in a high-oxygen content exhaust flow from an engine that is controlled to operate by cyclically burning lean and rich mixtures of air and fuel. The catalyst materials of the exhaust aftertreatment system comprise (1) lanthanum-based perovskite oxide particles to oxidize NO to NO2, (2) barium oxide particles to temporarily store NO2, (3) copper oxide nanoparticles chemically deposited onto particles of cerium oxides to reduce NOX to N2 and to generate NH3, and (4) particles of a selective reduction catalyst to temporarily store NH3 and to reduce any residual NOX to N2 and water before the exhaust flow from the engine is discharged to the atmosphere.
摘要:
A user can define a filter to applied be to one or more datasets. The filter includes a specification of a field to filter. Upon applying the filter to a dataset, if the specified field cannot be found in the dataset, a field in the dataset is selected as a default field to filter. Selecting what field in the dataset should be the default field is based on evaluating a set of rules. The default field is then filtered according to the filter criteria.
摘要:
A wound healing composition comprising an amount of heat shock protein effective to promote wound healing and a method thereof to apply the composition. A preferred heat shock protein is either full-length hsp90α or the middle domain plus the charged sequence of hsp90α. The composition is topically applied to skin wounds, covering the outer surface of the wound. The heat shock protein acts by promoting migration of both human epidermal keratinocyte and dermal fibroblasts to the wound in order to close, heal, and remodel the wound.

A black silicon based metal-semiconductor-metal photodetector includes a silicon substrate and a black silicon layer formed on the silicon substrate. An interdigitated electrode pattern structure is formed on the black silicon layer, which can be a planar or U-shaped structure. A thin potential barrier layer is deposited at the interdigitated electrode pattern structure. An Al or transparent conductive ITO thin film is deposited on the thin potential barrier layer. A passivation layer is provided on the black silicon layer. In the black silicon based metal-semiconductor-metal photodetector, the black silicon layer, as a light-sensitive area, can respond to ultraviolet, visible and near infrared light.
摘要:
A transcatheter delivery device for delivering a slide-and-lock stent to a stenosed lumen consists of an outer cannula (3), an inner sheath (2) and a balloon catheter (1). The distal end of the balloon catheter (1) is a balloon (5). The length and diameter of the balloon (5) can be chosen according to the requirement of the stent. A cone (4) is attached to the distal end of the balloon (5) to prevent the stent sliding to the distal end. The proximal part of the cone (4) can be inserted into the outer cannula (3) to maintain the external surfaces of the cone (4) and the outer cannula (3) on the same level. The inner sheath (2) is a little shorter than the balloon catheter (1) and extends to the proximal end of the balloon (5) so as to prevent the stent sliding to the proximal end.
