The bogie has good dynamic performance, higher structural safety, reliability and economic efficiency, and can be adapted to the requirement of the rapid development of high-speed railways.

Provided is a flow distribution device, which comprises a flow distribution member (50) in a concave structure, wherein the concave structure forms a flow distribution cavity (53) having an opening, the flow distribution member (50) is arranged inside a pressure container (10) in a hung fashion and located right below a nuclear reactor core (30), the opening of the flow distribution member (50) faces towards the nuclear reactor core (30), a central hole (54) is further formed in the centre of the bottom of the flow distribution member (50) in a penetrating fashion, the central hole (54) is located right below the nuclear reactor core (30), and a plurality of flow splitting holes (55) are further formed in the flow distribution member (50) in a penetrating fashion; and under the actions of the central hole (54) and the flow splitting holes (55), a coolant can uniformly and stably flow into the nuclear reactor core (30), and the coolant is effectively prevented from generating a vortex under the action of the central hole (54) so that the uniformity and stability of the coolant flow distribution are further improved; moreover, since no vortex is generated, the safety and reliability of the nuclear reactor are guaranteed and the occurrence of nuclear safety accidents is reduced. Also disclosed is a nuclear reactor assembly with the flow distribution device.

Systems and methods enable convenient and accurate searching, filtering, reviewing, and classification of electronic documents without the loss of metadata. A communication data source file is parsed into conversation-specific files that include message content and metadata. The message content and metadata are displayed on a computing device operated by a reviewer. To streamline the review process, the reviewer can filter display of the message content according to various metadata categories as well as search conversation-specific files using the metadata categories.

The present invention discloses methods and systems for transmitting data packets through a plurality of connections and through a gateway at a network node. The network node receives network performance observation report (NPOR) from the gateway. Based on the NPOR, the network node determines at least one of the plurality of wide area network (WAN) interfaces of the gateway for transmitting data packets. The network node then creates and transmits an in¬ struction to the gateway. When the network node transmits the data packets to the gateway, the network node also creates and transmits an instruction to the gateway to determine the WAN interface(s) of the gateway for transmitting the packets.

Micro-electro-mechanical systems lost circulation materials (MEMS-LCMs) of various sizes, shapes, and specific gravities may be used in a drilling fluid to determine the preferred LCMs for use in wellbore strengthening of the wellbore. For example, a method may include drilling at least a portion of a wellbore penetrating a subterranean formation with a drilling fluid that comprises a base fluid, a plurality of MEMS-LCMs, and a plurality of LCMs, wherein the MEMS-LCMs and the LCMs are substantially similar in size, shape, and specific gravity; measuring a first concentration of the MEMS-LCMs in the drilling fluid before circulating the drilling fluid through the wellbore; measuring a second concentration of the MEMS-LCMs in the drilling fluid after circulating the drilling fluid through the wellbore; performing a comparison of the first and second concentrations of the MEMS-LCMs; and changing a composition of the drilling fluid based on the comparison.

A container comprises a body of plastics material with a "bag-on-valve" arrangement. The bag depends from a valve and contains a post-foaming gel cleansing composition. A propellant is provided in the container outside the bag, so as to exert a pressure on the post-foaming gel cleansing composition in the bag, such that when the valve stem is depressed to open the valve the post-foaming gel cleansing composition is expelled through the valve stem. The container comprises a cap and the cap is provided with a conduit therethrough to guide the composition from the valve stem to an exit orifice. The conduit comprises an expansion chamber for receiving the composition from the valve stem, a neck having a smaller diameter than the expansion chamber for receiving the composition from the expansion chamber, and a nozzle provided with an exit orifice and having a diameter larger than the neck.
