Furthermore, a recent independent scientific study found there are significant "unknowns" about the safety of future UK fracking wells.
"These are significant unknowns to investors, but they are pretty important to determining the future of the industry".
The lack of publicly available data on the UK's onshore oil and gas drilling means there are significant "unknowns" about the safety of future fracking wells, according to a new study.
"There are significant unknowns about the local and global impacts of fracking, illustrated by the conclusion by seismologists that recent fracking in the North West was responsible for a minor earthquake".
The timing of release, the amount of available energy released, how and why it is partitioned into different energy forms and pathways, and the factors controlling these properties are significant unknowns in our understanding of substorm dynamics [ Koskinen and Tanskanen, 2002; Freeman and Morley, 2004; Morley et al., 2007].
Note, however, that there are significant limitations and unknowns involved in quantifying viral particles without direct data gathered from field tests (see Discussion).
However, this method can have limitations when deriving correlations or empirical models, as potential biological expression differences can create a large set of unknowns, especially where HCP profile differences are significant.
Such unknowns are compounded by significant inter-subject variations of the biliary tract microbiota were also observed (Additional file 6: Figure S4).
Some "unknown unknowns" are actually knowable.
Unknown unknowns are far more interesting.
In business, known unknowns are preferable to unknown unknowns.
