Geochemistry of Ni in the Cretaceous-Tertiary succession Fiskeler (Fish Clay) at Stevns Klint (Denmark): cheto-smectite of the black marl [PDF]
The Cretaceus-Tertiary (KT) boundary at Stevns Klint (the Højerup succession), Fiskeler, consists of a thin red clay layer overlain by a thick one of black marl. These two layers are made up mainly from cheto-smectite and biogenic calcite. The black marl

Summary: Let \(R\) be a ring. It is well-known that \(R\) is \(NI\) if and only if \(\sum_{i=0}^nRa_iR\) is a nil ideal of \(R\) whenever a polynomial \(\sum_{i=0}^na_ix^i\) is nilpotent, where \(x\) is an indeterminate over \(R\). We consider a condition which is similar to the preceding one: \( \sum_{i=0}^nRa_iR\) contains a nonzero nil ideal of \(R\)

Occurrence data of nickel in feed and animal exposure assessment
Abstract Nickel (Ni) is a silvery‐white, hard, ductile metal existing in oxidation states; in biological systems, Ni2+ is the prevalent form. All analytical results used to estimate animal dietary exposure were reported as Ni', without providing information on specific chemical species. Considering the data provided by Member states, among FoodEx level
