The commercial profile of the Amoco CD MgCl2 supported polypropylene catalyst is presented. The development, the unique method of preparation/production, with emphasis on particle morphology, and the parameters affecting particle size (PS), particle size distribution (PSD), and particle shape are discussed in detail. The outstanding performance of the catalyst, tailoredmade for the Amoco-Chisso...

Sentential negation in spoken Brazilian Portuguese (BP) has three possible structures: containing a negative particle only preverbally (NEG1), pre and post verbally (NEG2) or only post-verbally (NEG3). The choice of structure depends on sociolinguistic and pragmatic factors. This study investigates whether these structures also differ in prosodic patterns. NEG3 is of particular interest: since ...

This study examined the relationship between verb retrieval and verb-argument-structure properties in seven agrammatic aphasic patients using tasks requiring access to the verb's lexicon for both comprehension- and productionlike processes. Results showed intact comprehension of both nouns and verbs and noun naming, but impaired naming of verbs. Subjects also demonstrated near-normal performanc...

The topic of this paper is a kind of morphological structure that looks as if it might be formed within the syntax: Noun Incorporation. This is a feature of a wide range of languages, including (in its purest form) Mohawk, Chuckchee, Southern Tiwa, Classical Nahuatl, and many others; and it has attracted attention for quite some time. Adopting a classical formulation, Noun Incorporation is a co...

Verb alternations have been researched extensively in linguistics, but they have not yet received a systematic treatment in natural language generation systems; consequently, generators cannot make informed choices among alternatives. As a step towards overcoming this discrepancy, we review some linguistic work on several prominent alternations, revise and extend it, and suggest a set of rules ...
