This study presents a comprehensive and systematic description as well as statistical analysis of the natural fractures that cut through the QS outcrop in the Tabuk Basin, NW Saudi Arabia. These analyses were used to identify the factors that control the development of a fracture system in this ...
Measurements were performed using activation and off-line γ -ray spectrometric techniques. The experimental flux-averaged cross-section σ (E γ max) m for the nat Mo (γ , x n p) 95 m Nb reaction at the bremsstrahlung end-point energy range of 38–...
Forests harbor extensive biodiversity and act as a strong global carbon and nitrogen sink. Although enhancing tree diversity has been shown to mitigate climate change by sequestering more carbon and nitrogen in biomass and soils in manipulative experimen
The Department of Defense (DOD) is responsible for managing and maintaining nearly 27 million acres of land, water, and airspace on and around 320 installations and ranges across the United States. As a major land management agency, DOD invests significant resources to preserve natural landscapes,...
People now realize that this unhealthy situation must be changed,and that we must be able to develop in sustainable(可持续的)ways.That means growth with low carbon or development of sustainable products.In other words,we should keep the earth healthy while using its supply ...

Different types of natural resources - Natural resources conservation, exhaustible (sun, air) and inexhaustible (fuels) natural resources, renewable & non renewable resources. Water is a key natural resource for human society.
Gas sweetening is the major process used for the separation of acid gases (CO2 and H2S) from raw NG. CO2 removal from NG controls atmospheric pollution, improves the energy content of NG, and lowers the volume of gas delivered to the pipelines or stored into cylinders. The large hydrogen ...
