NUCLEAR ENGINEERING SCIENCES / 227 tion to complex variables. If the student's background is considered deficient for his planned course of study, an articulation program of background courses will be required. In certain cases, depending on the student's professional objectives, he may omit the master's thesis and substitute 12 credits of graduate-level course work, of which at least 9 credits are in nuclear engineering sciences, including a 6-credit (minimum) special project (NES 691). In such cases the com- pletion of 48 credits will meet the requirements for the non-thesis master's degree, with major in nuclear engineering sciences. The following Engineering Common Courses are available for graduate major credit: EGC 508-Fundamentals of Radiation Protection; EGC 578- Nuclear Chemical Technology; EGC 671--Introduction to Plasmas; EGC 672-Plasma Theory; EGC 675-Plasma Laboratory; EGC 677-Gas Lasers and Their Engineering Applications.
