Establishment on the chloride resistant clad rebar weld process in simulated seawater
To enhance the weld process of the new type of clad rebar construction in the marine environment, the weld process of the clad rebar was established. Four different weld processes were used to weld the clad rebars. The microscopy of the welded joints was

Ignition of Welding Arc and UV Actinic Hazard Evaluation
Welding arcs emit strong ultraviolet (UV) radiation, which could pose serious health risks for skin and eyes. According to Directive 2006/25/EC, UV hazard evaluation has to be performed in the working environment.

Mechanical and microstructural properties of S1100 UHSS welds obtained by EBW and MAG welding
The microstructures and mechanical properties of welds consisting of 20-mm-thick thermo-mechanically rolled and directly quenched S1100MC ultra high-strength steel (UHSS) plates were investigated. The welds were produced by means of metal active gas (MAG) welding and electron beam welding (EBW). Different heat inputs of the welding processes influenced

Settler Sociology: Eugenic Responses to Imperial Crises in the 20th Century
ABSTRACT In the twentieth century, academic concerns about changes in the racial demographics of the United States emanated from the potential crisis of settler colonial decline. In their references to previous empires, stories of contact between people groups, and changes in demographics, settler scholars worked to provide solutions to the ever ...
