Abstract: A method of testing the peritoneal function characterized in that providing that MTACun means the overall mass transfer/membranous area coefficient of urea nitrogen while MTACc means the overall mass transfer/membranous area coefficient of creatinine, the ratio of MTACun/MTACc calculated from the MTACun and MTACc is used as a check index of peritoneal function. Thus, patient~s future peritoneal function (peritoneal function increase mechanism) can be checked by the use of the ratio MTACun/c. In particular, the MTACun and MTACc can be obtained by performing an arithmetical operation of Pyle-Popovich model. Furthermore, in the method of testing the peritoneal function, the cell pore water permeability coefficient LpSc and overall water permeability coefficient LpS are calculated from Three Pore Theory model, thereby obtaining the ratio of LpSc/LpS, and this ratio of LpSc/LpS together with the above ratio of MTACun/MTACc can be used as a check index of peritoneal function.

Title: Dynamic membrane wafer assembly and method
Inventor: KAUL BAL K
IPC: B01D61/00
Filed: 2004-11-09
Abstract: A method for separating aromatic hydrocarbons from a feed stream. The method includes flowing the feed stream through a first channel within a first wafer assembly that may contain an underflow distribution weir. Next, the feed stream is exposed to a first thin film polymer membrane comprising at its feed-side surface a powdered adsorbant to enhance permeation of a desired component. A stream permeates through the first thin film polymer membrane, and the permeate is produced from the first wafer assembly. The retentate is directed via a redistribution channel (such as a tube) to a second wafer assembly that may contain an underflow distribution weir. This retentate is exposed to a second thin film polymer membrane. A second permeate stream is created that permeates through the second thin film polymer membrane. The second permeate stream is conducted into the permeate zone and ultimately produced from the second wafer assembly. An apparatus for separating aromatic components from a feed stream is also disclosed. In the preferred embodiment, the apparatus includes a series of tandem wafer assemblies. The wafer assemblies comprise a first wafer, second wafer and third wafer. First and second membrane members are disposed within the wafer assemblies.
