Abstract: A method for administering a composition for exploiting natural gas hydrates. The method includes the following steps: injecting the reagent A into the tube A; injecting the reagent B into the tube B; stretching the tube A and the tube B into a hydrate reservoir by using a reagent injection instrument; regulating a flow rate according to a proportion of each component; allowing the reagents to react at a preset reservoir position; and allowing water in the reservoir to participate in the reaction at the same time, wherein a reaction product is used for supporting the reservoir.

Abstract: The present invention relates to a reagent for exploiting natural gas hydrates, which includes a regent A and a regent B. The reagent A is PEG400-polyurethane prepolymer; the reagent B includes PEG400 and an initiator; and a volume ratio of the PEG400-polyurethane prepolymer, the PEG400 and the initiator is (1-3000):(1-1000):(1-2000). The reagent of the present invention has excellent performance and high stability, and can effectively “replace” the “water” of the natural gas hydrate; and moreover, the reaction is exothermic reaction to effectively increase the reaction rate, which reduces the energy loss on the one hand, and reduces the blockage of a gas passage caused by the secondary generation of the natural gas hydrates in a low-temperature high-pressure pipeline during transferring on the other hand.

Abstract: A method for treating obesity, insulin sensitivity, and related conditions involves administering to the subject a bacterium for overexpressing a N-acyl-phosphatidylethanolamine (NAPE) and/or a N-acylethanolamine (NAE). A composition includes a bacterium for overexpressing a N-acyl-phosphatidylethanolamine (NAPE) and/or a N-acylethanolamine (NAE); and an ingestible vehicle in which the bacterium is provided.

Abstract: A magnetic resonance multi-core array radio frequency device and a magnetic resonance signal receiving method are provided. The device comprises a radio frequency receiver which includes a radio frequency coil (11), a low noise preamplifier (13), a multiplexer (15), a radio frequency band-pass filter (17), a program control amplifier (19), a frequency synthesizer (21), a mixer (23), an analog to digital converter (29) and a controller (31). The controller (31) is used for controlling the multiplexer (15) to select a corresponding radio frequency coil channel, a corresponding filtering channel, gain of the radio frequency band-pass filter (17), and receiving a magnetic resonance digital signal transmitted by the analog to digital converter (29). Due to the multiplexer (15), there is no need to configure different circuits respectively for different nuclear magnetic resonance, redundancy of the circuits is reduced, and cost is reduced.
