Carbachol-evoked contractions of descending colon strips from patients with CC (A, B). Dose-response effects of carbachol on the amplitude of contraction of circular (Aa) and longitudinal (Ba) muscle ...

Extremal contractions which contract divisors to points in projective threefolds with ${\Bbb Q}\text{-factorial}$ terminal singularities are studied and divided into two categories: index increasing ...
