Long-term flow-through column experiments and their relevance to natural granitoid weathering rates

Betaproteobacteria growth and nitrification rates during long-term natural dissolved organic matter decomposition experiments

Free Cash Flow, Institutional Ownership and Long-Term Performance

Performance appraisal is a process which help shareholders make informed and optimal investment decisions. In recent decades, a long stream of research has devoted particular attention to the importance and impact of financial decisions on firm performance and firm value. The present study thus is primarily concerned with investigating the association between free cash flow and institutional ow...

Long-term rates of chemical weathering and physical erosion from cosmogenic nuclides and geochemical mass balance

Quantifying long-term rates of chemical weathering and physical erosion is important for understanding the long-term evolution of soils, landscapes, and Earth’s climate. Here we describe how long-term chemical weathering rates can be measured for actively eroding landscapes using cosmogenic nuclides together with a geochemical mass balance of weathered soil and parent rock. We tested this appro...

Strong tectonic and weak climatic control of long-term chemical weathering rates

The relationships among climate, physical erosion, and chemical weathering have remained uncertain, because long-term chemical weathering rates have been difficult to measure. Here we show that long-term chemical weathering rates can be measured by combining physical erosion rates, inferred from cosmogenic nuclides, with dissolution losses, inferred from the rock-to-soil enrichment of insoluble...
