Abstract: The present disclosure discloses a method of promoting rice growth using artificial humic acid synthesized by catalysis of nanoscale Ferric oxide, belonging to the field of nanoscale agriculture. The present disclosure discloses a method for synthesizing artificial humic acid from waste biomass with catalysis of transition metal, including the following steps: adding a mixed solution of an alkali, a transition metal catalyst and water into a biomass raw material, and carrying out catalytic reaction at 160-250° C. for 6-48 hours. The artificial humic acid can accelerate germination of rice, effectively promote growth of the rice (the root activity is improved by 166.76% and the net photosynthetic rate is improved by 72.08%), improve the absorption of water and nutrients and the transport of nutrients by rice roots and improve the ability of rice to resist oxidative stress and salt stress.

Abstract: A glucocerebroside compound, a pharmaceutical composition thereof, and the use of the glucocerebroside compound and the pharmaceutical composition thereof in the preparation of drugs for preventing or treating immune-related diseases.

Abstract: A segmental joint of cast-in-place UHPC bridge beam. The joint comprises a female joints at an end of a first segment and male joints at an end of a second segment, wherein each female joints and the male joints are correspondingly connected to form a tongue-and-groove connection, and each of the male joints is of a structure with big outer part and small inner part. The beam segment joint of the present disclosure improves the structural strength of the bridge and facilitates on-site construction, which not only applies to the joint connection between the segmental cast-in-place UHPC beam segments and the construction of the segmental cast-in-place UHPC beam segment, but also to joint connection of UHPC bridge deck of UHPC-steel composite beam and of full UHPC bridge deck of UHPC composite box girder with corrugated steel webs and to UHPC bridge deck construction.

Abstract: The present disclosure relates to a segmental joint of cast-in-place UHPC bridge beam, and belongs to the field of bridge structure. The joint comprises a plurality of female joints disposed at an end of a first segment and a plurality of male joints disposed at an end of a second segment, wherein each female joints and the male joints are correspondingly connected to form a tongue-and-groove connection, and each of the male joints is of a structure with big outer part and small inner part. The beam segment joint of the present disclosure not only applies to the joint connection between the segmental cast-in-place UHPC beam segments and the construction of the segmental cast-in-place UHPC beam segment, but also to joint connection of UHPC bridge deck of UHPC-steel composite beam and of full UHPC bridge deck of UHPC composite box girder with corrugated steel webs and to UHPC bridge deck construction.
