A screening of amorphous, heptahydrate, and tetrahydrate forms disodium guanosine 5′-monophosphate is investigated using an antisolvent crystallization process with the aim to selectively produce each solid form. The concentrations solution are monitored by in situ Raman spectroscopy a calibration tool. Particle sizes particle counts measured elapsed time focal beam reflection measurement. Conc...

Although discriminating between all efficient decision making units (DMUs) with identical efficiency is a very important subject in data envelopment analysis (DEA), it may not be an easy task, particularly when the decision maker wants to select one and only one efficient DMU among all. There are some papers that have proposed methods for finding an efficient DMU as the most efficient one but h...
