Pienemann (1998, 2015) put forward Processability Theory to enlighten why language learners follow definite developmental paths. The aim of the present study was to run a comparative investigation into the difficulty order of different grammatical structures for male and female Iranian EFL learners predicted by Processability Theory. 185 Iranian university students took part in this study. They...

Processability Theory, a component of the cognitive approach to second language acquisition tries to enhance understanding of how the interlanguage knowledge systems can be restructured by second language learners (Pienemann, 1998, 2015). The present study intended to run a similar investigation into the syntactic development of Right-Brain and Left-Brain Dominant Iranian EFL learners based on ...

The processability of a phenylethynyl terminated imide resin matrix (designated as PETI-5) composite is investigated. Unidirectional prepregs are made by coating an N-methylpyrrolidone solution of the amide acid oligomer (designated as PETAA-5/NMP) onto unsized IM7 fibers. Two batches of prepregs are used: one is made by NASA in-house, and the other is from an industrial source. The composite p...
