Urinary estriol measurement has been widely accepted as a useful indicator of fetoplacental status. Classically, glucuronide conjugates of estriol have been cleaved with soluble /3-glucuronidase (EC 3.2.1.31) before extraction and measurement. We have developed a system in which urine is injected directly into a “high-performance” liquid chromatograph and the conjugates are cleaved on-line in a...

Effect of porosity on grain growth is both the most frequent and technologically important situation encountered in ceramic materials. Generally this effect occurs during sintering, however, for nuclear fuels it also becomes very important under reactor irradiation conditions. In these cases pores and gas bubbles attached to the grain boundaries migrate along with the boundaries, in some circum...

The dynamic behavior of ozonation with pollutants in a countercurrent bubble column is studied for the model establishment. Bubble columns have been widely used for an ozonation system in the plants and laboratories. In addition, a countercurrent bubble column has been commonly recommended than a cocurrent one because it has a higher ozone transfer efficiency. Therefore, the investigation of th...

In this investigation, CFD simulation is presented to study the hydrodynamic of bubbly flow and mass transfer in bubble column using EulerianEulerian Multifluid approach with a standard kε turbulence model. unsteady state method for modeling the multiphase flow and mass transfer from air to de-aerated water and the column hydrodynamics. Understanding the complexity of the fluid dynamics and mas...

Separation of proteins from whey; namely α – Lactoglobulin and β – Lactalbumin was obtained using the bubble foam column technique. Two types of whey were conducted in this study; yogurt whey and cheese whey. The effect of gas flow-rate and the height of the whey (liquid holdup) inside the column were studied at room temperature and at constant pH of whey. Whey used here obtained from local dai...
