Hydraulic fracturing in cells and tissues: fracking meets cell biology [PDF]
The animal body is fundamentally made of water. A small fraction of this water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and chromatin.

Hydraulic fracturing or also know as fracking, the removal of natural gas and oil from shale rock, took off in the 1990s, but the anti-fracking movement didn't start taking notice until 2005. Fracking began to take place in the the south and the middle of the United States, because those areas are not known for have environmental activists.

The Human Right to Water and Unconventional Energy [PDF]
Access to water, in sufficient quantities and of sufficient quality is vital for human health. The United Nations Committee on Economic, Social and Cultural Rights (in General Comment 15, drafted 2002) argued that access to water was a condition for the ...

Study on variation law of coal disturbance stress in hydraulic fracturing test
In order to explore the variation of disturbance stress in the coal seam around the fracturing borehole in the process of hydraulic fracturing, taking the 1703 coal face of Junlian Jinzhong Coal Mine Company as the test site, on the basis of determining
