... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

... The caption to Color Figure 3 refers to the source 1928+734, which should be 1928+738. In the summary section on page 49 (Murphy et al.), the sentence "In that time, we have observed a variety of structural changes in the inner jet region near the region." should read "In that time, we have observed a variety of structural changes in the inner jet region near the core." In the references on page 175 (Fomalont et al.) and page 182 (Moellenbrock et al.) ...
