Defensive strategies of Norway spruce and Kurile larch heartwood elucidated on the micron-level

Scientific Reports, 2021
To decarbonize the building sector, the use of durable wood materials must be increased. Inspiration for environmentally benign wood protection systems is sought in durable tree species depositing phenolic extractives in their heartwood.

Mechanism of the strong earthquake triggered by high pressure fluid in reservoir: A case study of the 5.12 Wenchuan earthquake

Dizhi lixue xuebao, 2021
At present, the mechanism of earthquake is still based on elastic rebound theory—Earthquake is caused by the release of elastic energy of rock strata due to fault dislocation.

Southern Tibetan rifting since late Miocene enabled by basal shear of the underthrusting Indian lithosphere

Nature Communications, 2023
Syncontractional extension is prominent in present-day Tibet, but its origin remains vigorously debated. Several deep-seated geodynamic processes (e.g., Indian underthrusting, horizontal flow, and mantle upwelling) have been linked to Tibetan rifting ...

Reconstruction of critical coalbed methane logs with principal component regression model: A case study

Energy Exploration & Exploitation, 2020
Wireline logging plays a critical role in coalbed methane exploration. However, the lack of crucial log data, such as neutron and sonic logs, makes coalbed methane exploration difficult.

The Impact of Unimplemented Large-Scale Land Development Deals

Frontiers in Sustainable Food Systems, 2022
Although many land deals are never implemented to production stage, little is known about how abandoned projects affect local communities and the government agencies that promote them. This article analyses the effects on local actors, their land access,

A systematic look at chromium isotopes in modern shells – implications for paleo-environmental reconstructions [PDF]

Biogeosciences, 2018
The chromium isotope system (53Cr ∕ 52Cr, expressed as δ53Cr relative to NIST SRM 979) in marine biogenic and non-biogenic carbonates is currently being evaluated as a proxy for the redox state of the ocean.

Craton Destruction Induced by Drastic Drops in Lithospheric Mantle Viscosity

Earth and Space Science, 2022
The disruption of the mantle roots of cratons is common after cratonization. Craton destruction, which is characterized by severe lithospheric thinning, extensive thrust and extensional deformation, basin filling, and intense thermal activities, is ...
