Abstract: The present disclosure discloses a method for targeted regulation of soil microbes to synchronize heavy metal/metalloid transformation and greenhouse gas emission reduction and use. The present disclosure discovers that by compounding methionine with an organic acid salt, the obtained formulation can significantly increase the ability of the soil microbes to promote arsenic methylation in a targeted mode, and meanwhile, and the methane production is effectively reduced in the presence of the methionine. In the present disclosure, the methionine/organic acid salt formulation is further loaded into a modified biochar material of a porous structure, so as to achieve the effect of slow release. The method of the present disclosure may effectively reduce absorption of inorganic arsenic by rice, achieve a significant reduction in the proportion of inorganic arsenic in the total arsenic in the rice and inhibit methane emission of the soils and reduce methane emission at the same time.

Abstract: The present disclosure provides an intelligent cataloging method for all-media news based on multi-modal information fusion understanding, which obtains multi-modal fusion features by unified representation and fusion understanding of video information, voice information, subtitle bar information, and character information in the all-media news, and realizes automatic slicing, automatic cataloging description, and automatic scene classification of news using the multi-modal fusion features. The beneficial effect of the present disclosure is that it realizes the complete process of automatic comprehensive cataloging for the all-media news, and improves the accuracy and generalization of the cataloging method, and greatly reduces the manual cataloging time by generating stripping marks, news cataloging descriptions, news classification labels, news keywords, and news characters based on the fusion of multi-modes of video, audio, and text.

Abstract: An iron-carbon composite material and a preparation method thereof are disclosed. The iron-carbon composite material includes a three-layer core-shell structure, which successively includes a porous graphite carbon outer layer, an iron carbide intermediate layer and a nano zero-valent iron core from outside to inside. The present invention wraps nano zero-valent iron in porous graphite carbon and iron carbide, which can prevent the oxidation of nano zero-valent iron, while iron carbide effectively improves the ability to fix arsenic, realizing high efficiency and long-term use of nano zero-valent iron. Iron carbide may effectively adsorb and fix arsenic, and especially efficiently oxidize As(III) to relatively low-toxic As(V).

Abstract: A single-point dual sensor-based leakage method and system for a gas-liquid stratified flow pipeline includes a single-point dual sensor-based leakage formula for a pipeline to be detected; installing two sensors at the same point of one end of the pipeline, a signal collected by the bottom sensor being an acoustic wave propagated by liquid in the pipeline, and a signal collected by the top sensor being an acoustic wave propagated by gas in the pipeline; processing the two acoustic waves to obtain a time difference; and substituting the acoustic velocity in a gas and the time difference into the single-point dual sensor-based leakage formula. The installation of sensors at two ends of a pipeline, avoids missing detection of leakage acoustic wave signals by a single sensor, reduces the number of installed sensors, and is low in cost, high in safety and strong in applicability to a gas-liquid stratified flow pipeline.

Abstract: A portable workstool suitable for carrying or use by a human subject is provided. The workstool includes a stoolmember having a frame and a pad. A detachable pouch having two handles for portability is connected to the stoolmember. The stool is placed in a functional mode for sitting and working in the conventional fashion. The pouch is configured to provide ergonomic storage and access to tools and the like while providing space-efficient storage of such because the pockets are immediately beneath the user.

Abstract: An article transport and organizer which can conveniently be used either as a tote bag for transport and storage of small articles or alternatively can be used in connection with an empty container such as a five-gallon bucket for the transport and storage of larger articles as well as for the transport of smaller articles and tools. The apparatus includes a removable shoulder strap that can be used to conveniently transport the apparatus when it is being used as a tote bag. The inner and outer skirt-like walls of the apparatus are provided with a plurality of spaced-apart pockets which are adapted to receive and organize hand tools and other small articles. Easy-to-operate zipper mechanisms are provided for interconnecting together the lower margins of the outer skirt-like walls so as to convert the apparatus from a bucket organizer into a tote bag.
