Typically, no requirements and design specifications exist and, therefore, also no traceability information. While especially the long-term utility of such information is well known, an important question in reengineering is whether installing it can have immediate benefits in the course of th...

متن کاملPhytosterols Are Minor Components of All Vegetable
Supercritical carbon dioxide (SC-CO,). fractionation technique was evaluated as an altemativeprocess for reducing the free-fatty-acid (FFA) content and minimizing the phytosterolloss of rice bran oil (REO) during the process. The effects of pressure (20.5 to 32.0 MPa) and temperature (45 to 80 DC) for isothermal operation of the column on the composition of the resultant fractions were exarnine...
