Abstract: Disclosed are a shield tunnel segment structure and a construction method thereof. The shield tunnel segment structure includes segment blocks sequentially spliced in a circumferential direction. Each segment block forms a closed annular segment structure, and outer diameters of adjacent annular segment structures gradually increase in an axial direction. At least two adjacent segment blocks of the same annular segment structure form an annular inner groove, and at least one segment block of the adjacent annular segment structures is provided with an inner bump which matches the annular inner groove. At least two adjacent segment blocks of the same annular segment structure form an annular outer groove, and at least one segment block of the adjacent annular segment structures is provided with an outer bump which matches the annular outer groove. The annular outer grooves and the annular inner grooves are staggered in the circumferential direction.

Abstract: Described is an adhesive coating that can be applied, for example, to a surface of the insulation product. The adhesive coating includes between about 15-40% by weight of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA), between about 15 and 50% by weight of the adhesive coating of a polyvinyl alcohol, between about 0.05% and 1.0% by weight of a homogenizer, and between about 20 and 40% by weight of the adhesive coating of a starch paste. The adhesive is activated with the application of liquid water.

Abstract: A fiberglass reinforced aerogel composite may include coarse glass fibers, glass microfibers, aerogel particles, and a binder. The coarse glass fibers may have an average fiber diameter between about 8 ?m and about 20 ?m. The glass microfibers may have an average fiber diameter between about 0.5 ?m and about 3 ?m. The glass microfibers may be homogenously dispersed within the coarse glass fibers. The aerogel particles may be homogenously dispersed within the coarse glass fibers and the glass microfibers. The fiberglass reinforced aerogel composite may include between about 50 wt. % and about 75 wt. % of the aerogel particles. The binder bonds the coarse glass fibers, the glass microfibers, and the aerogel particles together.

Abstract: A method of breeding a hypoxia-tolerant Megalobrama amblycephala strain, including: (1) screening genes associated with hypoxia tolerance in Megalobrama amblycephala based on transcriptome data; (2) screening SNP sites from the genes associated with hypoxia tolerance; and (3) applying a haplotype of the SNP sites in the molecular marker-assisted breeding of Megalobrama amblycephala to obtain the hypoxia-tolerant Megalobrama amblycephala strain. The genes associated with hypoxia tolerance include Epo, Hif1?, Hif2?, VhI, Hif1an, Vegfaa Egln1a, Egln1b, Egln2 and Egln3, and the haplotype of the SNP sites is T397T715 of gene Egln2.

Abstract: Systems and methods for making a waterproofed concrete wall assembly, such as for a basement wall. A form is constructed. At least a first side of the form is made of one or more boards having a polymer foam and a fibrous facer. At least some of the boards have perimeter edges shaped such that some adjacent boards overlap at the shaped perimeter edges. Concrete is poured into the gap between the sides of the form, and is allowed to harden. The other side of the form may be removed, while leaving the boards of the first side of the form in place adjacent the hardened concrete. Some of the concrete is infused into the fibrous facers of at least some of the boards.

Abstract: A method for producing an insulation product may include providing an aqueous solution. The aqueous solution may include coarse glass fibers, glass microfibers, aerogel particles, and a binder.
