The objective of this work is to innovatively apply the boundary element method (BEM) as a general modeling strategy deal with complicated reservoir problems, especially those related heterogeneity and fracture systems, which are common challenges encountered in practice engineering. transient flow behaviors reservoirs containing multi-scale heterogeneities enclosed by arbitrarily shaped bounda...

When did the Anthropocene begin? A mid-twentieth century boundary level is stratigraphically optimal
We evaluate the boundary of the Anthropocene geological time interval as an epoch, since it is useful to have a consistent temporal definition for this increasingly used unit, whether the presently informal term is eventually formalized or not. Of the three main levels suggested e an ‘early Anthropocene’ level some thousands of years ago; the beginning of the Industrial Revolution at ~1800 CE (...
