NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

A drug is infused continuously intravenously (IV) for treatment of a particular disease. The volume of the body fluid V = 16 liters. The drug is excreted (removed) through the kidneys at rate ke , proportional to the concentration of the drug in the body fluids. The drug is ineffective and not used by the body if its concentration is below Cmin and becomes poisonous if the concentration goes over Cmax . It is metabolized at a rate km as the concentration is >=Cmin. Let the parameter values Cmin= 4 mg/l, Cmax =40 mg/l, ke = 0.2/hr and km = 0.3/hr.a. How much is the maximum possible rate of infusion of the drug?b. How long the drug would continue to be effective if the infusion has been stopped as the concentration reached at the maximum level?
Polycarbonate, PC, is used for aircraft canopies. A batch of this polymer was found to fail prematurely when impacted by a 4 pound bird during qualification studies.
