Estimation of rock properties by NMR relaxation methods
Two often used permeability models, which are based on logarithmic mean of relaxation time distribution and irreducible water, were examined. The model based on irreducible water was found to be more suitable than the model ...
Analysis and modelling of the effects of micellar solubilization on the degradation rates of n-alkanes
The transport, uptake and degradation of hydrocarbons by microorganisms has been a subject of interest for many years. The inherent low solubility of most hydrocarbons has been thought to be one of the limiting factors in ...
Methane emission from irrigated rice cultivation: Quantities, models and practice
Three experiments focused on the contribution of rice productivity to methane emission were conducted in Texas flooded rice paddy soils during 1994-95 growing seasons. Measurements of methane emission from different rice ...
Transient permeate flux analysis, cost estimation, and design optimization in crossflow membrane filtration
A generalized model is formulated to predict the time-dependent permeate flux by extending previous models to include the particle transport mechanisms of Brownian diffusion, shear-induced diffusion, inertial lift and ...
In vivo phosphorus-31 and carbon-13 nuclear magnetic resonance spectroscopy to study cellular metabolism
Nuclear magnetic resonance spectroscopy has emerged as a valuable tool for engineers for noninvasive, real-time studies of cellular metabolism. Two applications of NMR for studying cellular metabolism were investigated in ...
