The study focuses on the medium modifications to the three twist-two quark lightcone momentum distributions and associated structure functions. To achieve this, the Nambu-Jona-Lasinio model was utilized, with the proper-time regularization scheme, in which confinement is simulated by eliminating unphysical thresholds for nucleon decay into quarks. The EMC effect was readily reproduced. However the main focus of this study was on a new ratio, referred to as the polarized EMC effect. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1275563 / Thesis (Ph.D.) -- University of Adelaide, School of Chemistry and Physics, 2006
