In transboundary river basins, political borders oftentimes trace shared rivers across a basin. A border between territories can be seen as a space that is separated; however, it is actually one with the potential to unite populations and environments. A river basin is generally defined by its topography and hydrology....
Pre-Tertiary metamorphic rocks, Jurassic granitic intrusions,
and Eocene basalts are exposed along the North Fork of the John Day
River at its confluence with Granite Creek. Geochemical and textural
evidence suggest greenschist-metamorphosed, strongly sheared,
volcanogenic rocks originated in an island-arc environment. These
greenstones were apparently intruded during the Late Permian...
The spatial distribution and geologic histories of submarine volcanoes provide insight into submarine eruptive behavior, deep earth processes and plate tectonics.

Farmlands, grasslands, and savannas in semi-arid sub-Sahelian Africa have the potential to store
carbon (C) in soil. There is a great need to manage ecosystems to increase C storage in semipermanent
soil pools. This will improve soil quality, impede desertification and by reducing
atmospheric CO₂ levels, will slow climate change....
In wood-based composites, the glue-line (interface) between wood-strands affects the stress transfer from one member to the next. The glue-line properties determine the rate of load transfer between phases and these properties depend on wood species, surface preparation, glue properties, glue penetration into wood cells, and moisture content of the...
