Column Profiles for Membrane Column Sections

A novel graphical method of analysing continuous membrane separation systems has been developed. The method is applicable to all counterand co-current membrane modules – single-stage, cascades, and membrane columns. All configurations can be broken down into “column sections”, no matter how complex the arrangement. Each column section, which resembles a typical single-stage separator, is modell...

Column Generation

Column generation is an indispensable tool in computational optimization to solve a mathematical program by iteratively adding the variables of the model. Even though the method is simple in theory there are many algorithmic choices and we discuss the most common ones. Particular emphasis in put on the dual interpretation, relating column generation to Langrangian relaxation and cutting plane a...

Clinical Skills Centers Standards

Introduction. Setting up “Clinical Skills Labs” has been started in some Iranian medical universities since five years ago. In an educational workshop for Clinical Skills Labs managers in January 2001, many managers stated that if there were standards for these centers it would help them define the necessities of the center. These standards would also make the basis for internal and external ev...
