Abstract: An induced earthquake evaluation method for hydraulic fracturing activated faults includes obtaining an induced earthquake evaluation unit, cumulative injection equivalent energy, induced earthquake probability of fault type, induced earthquake probability of fault distance, hydraulic fracturing fluid diffusion capacity in fractured formation, new effective fault stress after fracturing, formation fluid pressure change rate and cumulative released equivalent energy. The probability of induced earthquake by hydraulic fracturing can be obtained. The induced earthquake possibility of each evaluation unit or single well under different stages of hydraulic fracturing, different construction injection methods and production conditions can be quantitatively evaluated. The method provides a quantitative result that can provide data support for optimizing hydraulic fracturing and reducing induced earthquake hazards.

Abstract: A highly parallel microfluidic blood separation device for isolation of variety of analytes for large-scale clinical trials. The device can be utilized for isolation of number of different target analytes, which may be the starting materials for variety of diagnostic methods including NGS, PCR, FISH, IHC, and others. Separation is achieved via magnetic sheath flow principals and is highly parallel. The separation device achieves effective magnetic separation, functions during sample flow in a vertical geometry and may fasten to standard multi-well plates for highly multiplexed sample recovery. Operating in vertical orientation allows multiplexing, more cards/slot/bay on instrument, allows effective use of real estate on instruments and bench tops.

Abstract: Disclosed is an external gas heating device of a coal pyrolyzing furnace. The external gas heating device is positioned on the middle part of a coal pyrolyzing furnace body and around the outer wall of a carbonizing chamber and comprises more than one group of first gas heater and second gas heater that have the same structure and a gas reversing device. The gas reversing device supplies air and purified gas into a combustion chamber of the first gas heater to be combusted and meanwhile sucks hot waste gas from a combustion chamber of the second gas heater. In the same way, the gas reversing device supplies air and purified gas into the combustion chamber of the second gas heater to be combusted and meanwhile sucks hot waste gas from the combustion chamber of the first gas heater.
