Modified correction for predicting slip velocity of oil-water two-phase bubble flow in large-diameter pipes
The slip velocity between phases is an important parameter for evaluating the volumetric flow rate of each phase in vertical pipes. This paper presents an improved empirical correction for calculating the slip...

Contributions of pore-throat size distribution to reservoir quality and fluid distribution from NMR and MIP in tight sandy conglomerate reservoirs
Overall pore-throat size distribution is a critical foundation for evaluating tight sandy conglomerate reservoirs. However, the pore-throat size cannot be easily obtained from a single technic due to the compl...

l-Asparaginase release from Escherichia coli cells with aqueous two-phase micellar systems
A method was proposed to release and separate l-asparaginase (EC 3.5.1.1) from Escherichia coli ATCC 11303 cells with aqueous two-phase micellar systems. The systems were composed of K2HPO4 and Triton X-100. The ...
