Land subsidence has created major ecological problems in China because 90% of the coal is mined from underground mining using high extraction longwall mining systems, in contrast to several other large producers of coal around the globe (USA, India, and Australia) who produce a significant amount of their coal production using surface mining methods (BP Statistics).
The Quebec mine cohort, in contrast, suffers from several exposure assessment limitations, such as incomplete job history information and undocumented moving between mines and mills; the exposure response was relatively flat.
Note that in [60], the determination of significance thresholds for subgraph size dependent density is incorporated into a mining algorithm which, in contrast to our approach, partitions the networks into a fragmentary collection of subgraphs hence outputs an incomplete, non-overlapping collection of modules.
Consequently, the majority of this research has focused on regions with large open pit mining activities, and, in contrast, the environmental effects of in-situ extraction are relatively unknown.
Slag piles from mining activities are common worldwide, but in contrast to mine tailings the environmental impact of runoff from slag piles is less documented.
In contrast, annual mining production has plunged to $27 million, less than 10percentt of the 1996 level.
In contrast, text mining of literature-based information relies on published miRNA to mRNA target interactions, most of which have been confirmed experimentally.
Locus-by-locus de novo development is costly and time consuming, in contrast to mining from EST sequence databases.
Impacts on forest communities were in large part negative and huge investment in mining were in sharp contrast with levels of poverty and environmental degradation.
In contrast, [10] proposed mining with a minimum "improvement" threshold.
