Abstract: A biochemical sludge and physicochemical sludge separate sampling device for identifying attributes of sludge, includes a sludge extraction assembly, and a biochemical reaction tank and a physicochemical reaction tank which are respectively connected to the sludge extraction assembly through connection pipelines. The sludge extraction assembly includes an outer shell, a porous plate clamped to an inner bottom of the outer shell, and a sampling dish. A drain pipe is arranged at a lower end of the outer shell. The sampling dish is provided with a biochemical sludge cavity and a physicochemical sludge cavity. Filter cloth is arranged at inner bottoms of the biochemical sludge cavity and the physicochemical sludge cavity. Electric extrusion stems are arranged at an inner top of the outer shell; and the electric extrusion stems are provided with extrusion plug plates.

Abstract: A system for a sandy soil landfill solid waste polluted river channel, includes a ground water interception and diversion system and a river channel ecological remediation system. The ground water interception and diversion system includes a water intake well arranged upstream of ground water in a landfill area, a buffer pool communicated with the water intake well, and a wastewater treatment system communicated with the buffer pool. The water intake well, the buffer pool, and the wastewater treatment system are communicated through a wastewater pipe. An electric wastewater valve and a variable frequency water pump are arranged on the wastewater pipe in sequence. The river channel ecological remediation system includes an impermeable layer arranged at a bottom of a river channel and ecological bank protections arranged on both sides of a river channel slope.

Abstract: Provided is a bispecific antibody, comprising a first antigen-binding moiety and a second antigen-binding moiety, wherein a paired domain of the first antigen-binding moiety comprises an amino acid sequence of engineered HLA-I ?3 and an amino acid sequence of engineered ?2M. Also provided are an expression method for the bispecific antibody, a polynucleotide encoding the bispecific antibody, a vector and host cell containing the polynucleotide, a pharmaceutical composition containing the bispecific antibody, a fusion protein, and a conjugate.

Abstract: Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases associated with the proteasome. The peptide-based compounds include an epoxide or aziridine, and functionalization at the N-terminus. Among other therapeutic utilities, the peptide-based compounds are expected to display anti-inflammatory properties and inhibition of cell proliferation.
