steel research international, EarlyView.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

How to Fish With Respect: A Transformation of Human‐Fish Relations in Riverside Amazonia
American Anthropologist, EarlyView.ABSTRACT Riverside inhabitants of the Middle Xingu River Basin, in the Brazilian Amazonia, frequently say that it is important to respect animals and the forest spirits who protect them. In recent decades, however, the development of an iced fish industry in the region has changed what respect means and how it is expressed when it comes to fishing ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater
Groundwater Monitoring &Remediation, EarlyView.Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.
