Over the past 2 decades, biologists have come to appreciate that hybridization, or genetic exchange between distinct lineages, is remarkably common-not just in particular lineages but in taxonomic groups across the tree of life. As a result, the geno

In this paper, a grey iron was submitted to low temperature isothermal heat treatment, austempering, in order to obtain austempered grey iron (AGI). Tensile strength, Brinell hardness and tribological properties were determined for the as-cast condit

Carburizing implies the existence of a carbon gradient from the surface to the core of the steel, which in turn will affect both the critical temperature for austenite formation and the kinetics of the bainitic transformation during the austempering

Background Nutritional programming takes place in early development. Variation in the quality and/or quantity of nutrients in early development can influence long-term health and viability. However, little is known about the mechanisms of nutritional

Across the tree of life, species have repeatedly evolved similar phenotypes. While well-studied for ecological traits, there is also evidence for convergent evolution of sexually selected traits. Swordtail fish (Xiphophorus) are a classic model syste

Carbo-austempering processes have been established as a viable alternative to conventional carburized—quenched and tempered (Q&T) steels for components subjected to wear and contact fatigue conditions. However, little information is available about
