EVENT-CANCELLING SEMANTICS OF THE ENGLISH ASPECTUALIZER START AND ITS SERBIAN EQUIVALENT KRENUTI

The paper revisits the issue of semantic equivalency of two aspectual verbs, start and krenuti, which is proposed by xxx (2021a, 2021b). The present analysis focuses on the causative and dynamic semantic features of start and krenuti, with the aim of a contrastive analysis of the aspectual constructions headed by these two verbs. It is shown that both start and krenuti, provided that the necessary linguistic conditions are met, have the ability to “cancel” the event initiated via constructional phase modification. The conditions for such event-cancelling result from the lexical semantics of start and krenuti, as well as from the semantic co-composition on the level of the aspectual construction as a whole. The theoretical frame of the analysis is the presupposition and consequence account by A. Freed (1979). The contrastive analysis and presented theoretical conclusions are backed by a parallel corpus of 200 English and Serbian sentences compiled from the Corpus of Global Web-Based English (GlowBE 2013) and the Corpus of Contemporary Serbian Language (SrpKor 2013). Key words: aspectualizers, aspectual constructions, aspectual event, temporal structure, presupposition and consequence, event-cancelling

Microstructural Improvement of Eutectic Al + Mg2Si Phases on Al–Zn–Si–Mg Cast Alloy with TiB2 Particles Additions

In this study, the effects of adding TiB2 particles to eutectic Al + Mg2Si phases in aluminum alloys were analyzed. The eutectic Al + Mg2Si phases were modified effectively when a large amount of TiB2 was added, and changes in the shape, size, and distribution of the eutectic Al + Mg2Si phases were confirmed using a polarizing microscope and FE-SEM. The crystal structure of the TiB2 particles and Mg2Si phases were analyzed using HR-TEM, and the analysis confirmed that the TiB2 particles can act as heterogeneous nucleation sites. This paper intends to clarify the principle of phase modification of the eutectic Al + Mg2Si phases by TiB2 particles and proposes a new mechanism to improve Mg2Si phase modification when TiB2 particles are added.
