An 80%Ar-10%CO2-10%He ternary gas mixture was used as the shielding during narrow-gap welding of thick Q690E high-strength steel plates. Complete and defect-free welded joints were obtained, microstructure mechanical properties joint investigated. The weld zone consists a solidification area interlayer zone, heat-affected coarse-grain (CG-HAZ) fine-grain (FG-HAZ). microstructures are mainly lat...

Isotropic ultra-thin shells or membranes, as well cable–membrane structures, cannot resist loads at the initial state and always require a form-finding process to reach steady state. After this stage, they can work in pure membrane quickly experience large deflection behavior, even with small amplitude of load. This paper aims improve load-carrying capacity strength structures via exploiting ad...

This paper introduces the concept of Fg-metric Space. We generalize G-metric space. Some supporting examples are given.

Fibrinogen (Fg) has been recognized to play a central role in coagulation, inflammation and tissue regeneration. Several studies have used Fg deficient mice (Fg(-/-)) in comparison with heterozygous mice (Fg(+/-)) to point the proinflammatory role of Fg in diverse pathological conditions and disease states. Although Fg(+/-) mice are considered 'normal', plasma Fg is reduced to ~75% of the norma...
