Abstract: A solar chimney is described. The solar chimney comprising: an elongated enclosure configured to provide a fluid passage to receive light from at least one side of the elongated enclosure; and absorbers arranged in a staggered configuration within the fluid passage wherein at least one of the absorbers is offset in a direction along the fluid passage relative to at least one other absorber, each absorber being adapted to absorb energy from the light for heating up fluid in the fluid passage to create an updraft of the fluid. A method of ventilating a building using a solar chimney is also described.

Abstract: Provided are a continuous post-treatment method and device for a penem compound. The method includes the following steps: S1, performing continuous extraction on a reaction crude product of a penem compound, to obtain an extraction heavy phase and an extraction light phase; S2, performing continuous solid-liquid separation on the extraction heavy phase, to obtain a liquid phase separation product; S3, performing continuous pH adjustment on the liquid phase separation product until a pH value thereof is 6.1-6.3, to obtain pH-adjusted solution; and S4, performing continuous crystallization treatment on the pH-adjusted solution by a first crystallization solvent, to obtain a penem compound product. The use of the method for the post-treatment of the reaction crude product of the penem compound has the advantages of high treatment speed and high efficiency, and stable material properties and a low deterioration rate during the treatment, and has better control over the yield and purity of a target product.

Abstract: The present disclosure describes a semiconductor MRAM device and a manufacturing method. The device reduces magnetic field induction “interference” (disturbance) phenomenon between adjacent magnetic tunnel junctions when data is written and read. This semiconductor MRAM device comprises a magnetic tunnel junction unit and a magnetic shielding material layer covering the sidewalls of the magnetic tunnel junction unit. The method for manufacturing a semiconductor device comprises: forming a magnetic tunnel junction unit, depositing an isolation dielectric layer to cover the top and the sidewall of the magnetic tunnel junction unit, and depositing a magnetic shielding material layer on the isolation dielectric layer.

Abstract: An accounting method, system, device, and a computer-readable medium. The accounting method, system, device, and a computer-readable medium provide for measuring a time interval between arrival of two adjacent packets, comparing the measured time interval to a predetermined threshold, and determining whether the measured time interval is an active packet transfer time based on the comparison. Accordingly, an active packet transfer time in a connection is obtained.
