A SEMIANALYTICAL MODEL FOR SIMULATING FLUID FLOW IN TIGHT SANDSTONE RESERVOIRS WITH A BOTTOM AQUIFER


Characteristics and Rates of Microbial Processes in Clays of Different Mineral and Elemental Composition in Relation to Safety Prediction for ESB Clay Materials

Microbial activity in clay barrier materials during radioactive waste disposal can lead to a violation of important physicochemical properties of the barrier system as a whole, thereby reducing the safety of the storage facility.This work evaluates the activity of the microbial complex of five bentonite and two kaolin clays.All clay materials were

Phylogeny, ancestral ranges and reclassification of sand dollars

Abstract Classification of the Class Echinoidea is under significant revision in light of emerging molecular phylogenetic evidence.In particular, the sister-group relationships within the superorder Luminacea (Echinoidea: Irregularia) have been considerably updated.However, the placement of many families remains largely unresolved due to a series o
