The injected CO2 in a target formation can continue to migrate through permeable pathways due to geological heterogeneity as well as buoyancy. This movement drives a countercurrent flow of brine leading to increased residual phase trapping. The purpose of this simulation study is to understand the effects of geological structures, especially faults, on the dynamic behavior of the buoyancy-drive...

residual lignin of wood after mwl isolation was dissolved with 1-butyl-3-methylimidazolium chloride ionic liquid. chemical structure of isolated mwl from poplar wood (popolus deltiodes) and dissolved residual lignin were characterized with gas chromatography and 1d, 2d nmr techniques. analytical results showed that  popolus deltoides wood has more 4-(3-hydroxy-1-propenyl)-2-methoxy phenol units...

Hyperthennal-neutral beams have been proposed as a charge-free alternative to plasmas in select processing steps. Existing prototype sources include three generic types: gas-dynamic, ion-neutral-charge-exchange and ion-surfaceneutralization beam sources. We find that in surface-neutralization type sources, which have the highest flw residual current can still flow to the substrate. However, thi...

A control rod K5 of the 10 MW Budapest Research Reactor was damaged in 2004. We have applied both neutron and X-ray radiography to study the distribution of the residual material in the damaged K5. X-ray radiography visualized the main distribution of the residual materials, like different kinds of B4C and water, and the frozen gas bubbles, while neutron radiography displayed the fine structure...

The FDI approach to model-based diagnosis is considered. We present a method for residual generation that combines integral and derivative causality, and also utilizes equation system solvers and theory of differential-algebraic equation systems. To achieve this, a framework for computation of variables from sets of dependent differential and/or algebraic equations is introduced. The proposed m...

We examine the evolution of residual gas within tidally-limited dwarf galaxies and globular clusters. In systems where the gas sound speed exceeds about 10% of the central velocity dispersion, hydrostatic equilibrium causes the gas to have significant density at the tidal radius. In contrast to the stellar component, gas particles relax rapidly in response to mass loss. Gas lost through the Lag...
