Recent advances in genetic research have produced a surge of student interest in molecular biology/ molecular genetics courses. Molecular biology is a fast-paced field that constantly provides new insights into the living world and the role of humans within it. From a wide area of molecular biology, molecular genetics represents one of the major technological field of the twenty-first century. Its wide ranging, multi-disciplinary activities include polymerase cahin reactions, molecular marker based studies and the gene cloning. One of the main challenges for the instructor in such a course is...

This book investigates the effect of tray spacing on the dimensions, head losses and flooding tendencies in a sieve - tray distillation column. The system under consideration was chosen to be a 50:50 mole % mixture of methanol and water at its boiling point. The saturated liquid feed is separated into products streams of 99.5 mole % purity. For a given sieve tray (holes arranged in a triangular pitch) with fixed specifications of hole diameter, pitch, tray thickness, weir height and proportion of downcomer area, the variables were determined for values of tray spacing ranging from 0.5 feet...
