Heterogeneous catalysts for production of linear α-olefins from ethylene were prepared by the direct reaction of the α-diimine ligand [L: R-N=C(R')-C(R')=N-R; R' = Me and R = 2,6-Me2Ph (L5), 2,5-Me2Ph (L1), 2-MePh (L2), or Ph (L3); R' = 1,8-naphth-diyl and R = Ph (L4)] and Ni ion-exchanged fluorotetrasilicic mica. Only high molecular weight polyethylene was(More)
Abstract Purpose. Intravesical instillation of epirubicin (EPI) is one of the most effective adjuvant therapies for non-muscle-invasive bladder cancer after transurethral resection. We evaluated the optimal duration of EPI instillation in a multi-institution prospective randomized clinical study. Methods. Between June 1995 and May 1998, a total of 125(More)
