STATIC BENDING MECHANICAL PROPERTIES OF PRESTRESSED CONCRETE COMPOSITE SLAB WITH REMOVABLE RECTANGULAR STEEL-TUBE LATTICE GIRDERS

Static Bending Mechanical Properties of Prestressed Concrete Composite Slab with Removable Rectangular Steel-Tube Lattice Girders

In recent years, with the development of building technology, the Chinese construction industry has begun to gradually promote the prefabricated buildings to save on construction costs.Among them, composite slabs, as essential components of prefabricated buildings, have been widely used by designers mainly in favor of their low cost.However, is it

A transcontinental challenge--a test of DNA barcode performance for 1,541 species of Canadian Noctuoidea (Lepidoptera).

This pentair hose study provides a first, comprehensive, diagnostic use of DNA barcodes for the Canadian fauna of noctuoids or "owlet" moths (Lepidoptera: Noctuoidea) based on vouchered records for 1,541 species (99.1% species coverage), and more than 30,000 sequences.When viewed from a copyright-wide perspective, DNA barcodes unambiguously discrim
