New guidelines and suggestions for taking reliable effective relative permeability measurements in heterogeneous rocks are presented. The results based on a combination of high resolution 3D core-flooding simulations semi-analytical solutions the cores. Synthetic “data sets” generated using TOUGH2 subsequently used to calculate curves. A comparison between input curves “calculated” is assess ac...

environmental stresses trigger a wide variety of plant responses, such as altered gene expression to changes in cellular metabolism and growth. the several plant reactions exist to circumvent the potentially harmful effects caused by light, drought, salinity, pathogen infections and other stresses. a-tocopherol is the major vitamin e compound found in leaf chloroplasts. this antioxidant deactiv...

1. The relative permeability of the native P2X receptor channel to monovalent and divalent inorganic and organic cations was determined from reversal potential measurements of ATP-evoked currents in parasympathetic neurones dissociated from rat submandibular ganglia using the dialysed whole-cell patch clamp technique. 2. The P2X receptor-channel exhibited weak selectivity among the alkali metal...

A capillary pressure function is proposed for interpreting core-scale flow experiments. This function has been found suitable for a wide range of rock/fluid systems with different pore geometry and wettability characteristics. The petrophysical controls are reflected in the asymptotic values relating to irreducible saturation, and threshold capillary pressure, and in the shape parameters relati...
