Natural weathering on coated tropical woods

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Teak and pine are common wood species in Indonesia. The purpose of this research is to evaluate the performance of the coating layer in these wood species after six months natural weathering. The durability on natural weathering is evaluated due to microbial disfigurement (fungi or algae), checking and cracking, whereas ...

Contrasted Chemical Weathering Rates in Cratonic Basins: The Ogooué and Mbei Rivers, Western Central Africa

Frontiers in Water, 2021
Despite the absence of tectonic activity, cratonic environments are characterized by strongly variable, and in places significant, rock weathering rates. This is shown here through an exploration of the weathering rates in two inter-tropical river basins

Climate‐Smart Dairy Practices: The Role of Practice Clusters in Enhancing the Performance of Dairy Farms in Kenya

Agribusiness, EarlyView.
ABSTRACT Climate variability is affecting the productivity, profitability, and resilience of smallholder dairy producers in developing countries. The adoption of climate‐smart (CS) dairy practices has been promoted to mitigate these negative effects. However, while interest in dairy CS practices is growing, empirical evidence on their adoption patterns

Study of an abnormal occurrence of Oxisols in strongly undulated relief in the south of Minas Gerais, Brazil, with support of pXRF and geomorphology

Ciência e Agrotecnologia, 2021
Oxisols are the main soils in Brazil and they classically occur in stable and gentle geomorphic surfaces. However, in the south of Minas Gerais State, Oxisols have been observed under strongly undulated relief, a very rare condition for these soils in ...

Flowpath Partitioning Controls Chemical Weathering Fluxes in the Tropics

Water Resources Research
Tropical watersheds are thought to exert a strong control on the global carbon cycle because elevated temperature and rainfall rates promote the chemical weathering of silicate rocks.
