Galactic Evolution of Beryllium and Oxygen [PDF]
, 2000 We discuss the early evolution of beryllium and oxygen in our Galaxy by comparing abundances of these elements for halo and disk metal-poor stars. Both, O and Be rise as we go progressively to more metal-rich stars, showing a slope 0.41 +-0.09 ([Be/O] vs

Looking beyond stratification: a model-based analysis of the biological drivers of oxygen deficiency in the North Sea [PDF]
, 2016 Low oxygen conditions, often referred to as oxy- gen deficiency, occur regularly in the North Sea, a temperate European shelf sea. Stratification represents a major process regulating the seasonal dynamics of bottom oxygen, yet, low- est oxygen ...

Chemical evolution models with a new stellar nucleosynthesis [PDF]
, 1994 Numerical models for the chemical evolution of the Galaxy have been computed with the new stellar yields published by Maeder (1992). These metallicity dependent yields represent an important improvement in the chemical evolution of galaxies but there are
