This paper represents a pilot investigation of primed accentuation patterns produced by advanced Dutch speakers of Italian as a second language (L2). Contrastive accent patterns within prepositional phrases were elicited in a semispontaneous dialogue entertained with a confederate native speaker of Italian. The aim of the analysis was to compare learner’s contrastive accentual configurations in...

Purpose: The purpose of this experiment is to observe chemical reactions characteristic of common organic functional groups. The observations will be used to identify a set of unknown compounds Introduction: Most organic and biochemical compounds are composed of carbon, hydrogen, and a few other elements (such as oxygen, nitrogen, and sulfur). These compounds participate in a wide variety of re...
