The aim of this study is to investigate the effect of boundary conditions on the accuracy and stability of the numerical solution of fluid flows in the context of single relaxation time Lattice Boltzmann method (SRT-LBM). The fluid flows are simulated using regularized, no-slip, Zou-He and bounce back boundary conditions for straight surfaces in a lid driven cavity and the two-dimensional flow ...

wetlands as water resources have a special place in the semi-arid plateau of iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. ecological...

Ocean anoxic events (OAE) are characterized by increased organic content of marine sediment on a global scale with accompanying positive excursions in sedimentary and inorganic δ 13C values. To sustain the C exports burial required to explain isotope excursion, supplies nutrients oceans often invoked during ocean events. The potential source these is investigated this study for Oceanic Anoxic E...

Mass extinction is characterized by the loss of 50 - 90 + percent genetically and ecologically diverse species within 1 3.5 Myr intervals. Three conflicting theories exist: (1) Graded Extinction; (2) Stepwise (3) Catastrophic Extinction. These can only be adequately tested with high resolution (cm-scale) stratigraphic data spanning entire mass interval adjacent strata. Such are presently availa...
