Subsurface flow problems are inherently multiscale in space due to the large variability of material properties and in time due to the coupling of many different physical processes, such as advection, diffusion, reaction and phase exchange. Subsurface flow models still need considerable development. For example, nonequilibrium effects, entrapped air, anomalous dispersion and hysteresis effects can still not be adequately described. Moreover, parameters of the models are diffcult to access and often uncertain. Computational issues in subsurface flows include the treatment of strong heterogeneities and anisotropies in the models, the effcient solution of transport-reaction problems with many species, treatment of multiphase-multicomponent flows and the coupling of subsurface flow models to surface flow models given by shallow water or Stokes equations. With respect to energy and the environment, in particular the modelling and simulation of radioactive waste management and sequestration of CO2 underground have gained high interest in the community in recent years. Both applications provide unique challenges ranging from modelling of clay materials to treating very large scale models with high-performance computing. This book brings together key numerical mathematicians whose interest is in the analysis and computation of multiscale subsurface flow and practitioners from engineering and industry whose interest is in the applications of these core problems.

Students revisit Europe during the Middle Ages through guided practice activities, poems, songs, and an educational play packaged into a unique teacher resource book. This title integrates creative arts, innovative activities, and original music. Content is selected to coordinate with national standards in art, history and language arts. Two other important components of the book are a musical play and a pantomime. While entertaining students, it develops varied educational concepts and expands critical thinking skills. Students may: Stage the musical for an audience; act it out in class; or read it silently. All lyrics can be used as songs or read as poetry. Everything is reproducible. Grade 4-8.

Hidden Glory reveals the life and times of a plantation house, now over 250 years old. Human lifespan rarely exceeds one century; therefore this biography necessarily includes generations of owners and occupants in order to acquaint the reader with the main character, Hampton Plantation.

In 1816, Henry and Septima Rutledge left the security of Charleston, SC to establish a county seat on the Elk River in Franklin County, Tennessee. This book brings an emerging nation into focus, from colonial Charleston to frontier Nashville, from the Revolution to the War Between the States. Illustrated and indexed.

The content is selected to coordinate with National Standards for History, Standards for Grades K-4 and National Standards for United States History, Standards for Grades 5-12.
