ENVIRONMENTAL CHARACTERISTICS AND FORMATIONS OF POLYBROMINATED DIBENZO-P-DIOXINS AND DIBENZOFURANS


Perception of livestock ecosystem services in grazing areas

This study investigates how the ecosystem services (ES) linked to livestock grazing are perceived across countries.A total of 82 case studies collected from 42 countries via survey (53.7% cases from Europe and 46.3% from outside of Europe) have been analysed through a multivariate approach.In all, 18 non-provisioning ES were considered.Overall, the

Macro-fracture mode and micro-fracture mechanism of shale

Through the study of fabric characteristics, mechanical characteristics, crack and microstructure characteristics of shale, the micro-mechanism, controlling factors and fracture modes of shale macro-fracture are revealed.The macro-fracture of shale is affected by fabric characteristics, coring direction, confining pressure etc, and occurs when the
