    Abstract:
    GoalsThe causative/anticausative alternation has been the topic of much typological and theoretical discussion in the linguistic literature.This alternation is characterized by verbs with transitive and intransitive uses, such that the transitive use of a verb V means roughly 'cause to Vintransitive' (see Levin 1993).The discussion revolves around two issues: the first one concerns the similarities and differences between the anticausative and the passive, and the second one concerns the derivational relationship, if any, between the transitive and intransitive variant.With respect to the second issue, a number of approaches have been developed.Judging the approach conceptually unsatisfactory, according to which each variant is assigned an independent lexical entry, it was concluded that the two variants have to be derivationally related.The question then is which one of the two is basic and where this derivation takes place in the grammar.Our contribution to this discussion is to argue against derivational approaches to the causative/anticausative alternation.We focus on the distribution of PPs related to external arguments (agent, causer, instrument, causing event) in passives and anticausatives of English, German and Greek and the set of verbs undergoing the causative/anticausative alternation in these languages.We argue that the crosslinguistic differences in these two domains provide evidence against both causativization and detransitivization analyses of the causative/anticausative alternation.We offer an approach to this alternation which builds on a syntactic decomposition of change of state verbs into a Voice and a CAUS
    Porous SiC ceramics with multiple pore structures were fabricated via gelcasting and solid state sintering.A novel gelling agent of Isobam was applied and PMMA was used as both foam stabilizer and pore forming agent.The mechanical properties of porous SiC ceramics were investigated as functions of PMMA content, rotating speed of ball mill, and sintering temperature.With PMMA content increasing from 5wt% to 20wt%, the foaming effect was inhibited while the stability of bubbles increased.When the rotating speed was 220 r/min, the open porosities of the as-prepared SiC ceramics sintered at 2100 varied ℃ from 51.5% to 72.8%, and compressive strength varied from 7.9 to 48.2 MPa.With the rotating speed increasing from 220 to 280 r/min, the foaming effect was aggravated and the porosities of SiC ceramics sintered at 2100 increased.℃ While the sintering temperature increasing from 2050 to 2150 , ℃ the SiC ceramics prepared with PMMA content of 20wt% at rotating speed of 220 r/min decreased in the open porosities while increased in compressive strength.

    ZrB2 based composites containing 10 vol.-% carbon nanotubes (CNTs) are synthesised by spark plasma sintering at temperatures ranging from 1600 to 18008C and at an applied pressure of 25 MPa. The effects of sintering temperature on densification behaviour, microstructural evolutions and mechanical properties are presented. Results indicate that ZrB2-CNT composites fabricated at 16508C have the optimal combination of dense microstructure and properties. The fracture toughness is sensitive to the temperature change and reaches 7.2 MPa m1/2 for the CNT toughened ZrB2 ceramics, which is higher than the measured result for monolithic ZrB2 (3.3 MPa m1/2). The crack deflection and CNT pullout are the dominant toughening mechanisms.
