Abstract Thermodynamic analysis of the precipitation behavior, growth kinetic, and control mechanism of MnS inclusion in U75V heavy rail steel was conducted in this study. The results showed that solute element S had a much higher segregation ratio than that of Mn, and MnS would only precipitate in the solid–liquid (two-phase) regions at the late stage during the solidification process at the solid fraction of 0.9518. Increasing the cooling rate had no obvious influence on the precipitation time of MnS inclusion; however, its particle size would be decreased greatly. The results also suggested that increasing the concentration of Mn would lead to an earlier precipitation time of MnS, while it had little effect on the final particle size; as to S, it was found that increasing its concentration could not only make the precipitation time earlier but also make the particle size larger. Adding a certain amount of Ti additive could improve the mechanical properties of U75V heavy rail steel due to the formation of TiO x –MnS or MnS–TiS complex inclusions. The precipitation sequences of Ti3O5 → Ti2O3 → TiO2 → TiO → MnS → TiS for Ti treatment were determined based on the thermodynamic calculation.

Alkali Activated

This study aims to model grinding of a Polish ferronickel slag and evaluate the particle size distributions (PSDs) of the products obtained after different grinding times. Then, selected products were alkali activated in order to investigate the effect of particle size on the compressive strength of the produced alkali activated materials (AAMs). Other parameters affecting alkali activation, i.e., temperature, curing, and ageing time were also examined. Among the different mathematical models used to simulate the particle size distribution, Rosin–Rammler (RR) was found to be the most suitable. When piecewise regression analysis was applied to experimental data it was found that the particle size distribution of the slag products exhibits multifractal character. In addition, grinding of slag exhibits non-first-order behavior and the reduction rate of each size is time dependent. The grinding rate and consequently the grinding efficiency increases when the particle size increases, but drops sharply near zero after prolonged grinding periods. Regarding alkali activation, it is deduced that among the parameters studied, particle size (and the respective specific surface area) of the raw slag product and curing temperature have the most noticeable impact on the compressive strength of the produced AAMs.

Abstract Mirativity is a distinct grammatical category. In the literature, no mirative marker has been identified so far in Mandarin Chinese. This paper aims to argue that Mandarin Chinese is a language that has grammatical means of expressing mirativity. The sentence-final particle le (SF le) in Mandarin is a mirative marker in its own right. It encodes the information as newsworthy or surprising and occurs with different time references and Illocutions. Based on the data from SF le, this paper extends the definition of mirativity given by Hengeveld & Olbertz (2012) by proposing that mirativity can not only be targeted towards either the speaker or the addressee, but also towards both. Lastly, it is argued that mirativity should be accounted for at the layer of Communicated Content at the Interpersonal Level in Functional Discourse Grammar.

Abstract This study examined second language (L2) Chinese learners’ developmental patterns of pragmatic competence in two computer-mediated communication (CMC) conditions: (1) CMC with data-driven instruction embedded in the course of CMC and (2) CMC without data-driven instruction. Learners’ pragmatic competence was operationalized as their ability to use a Chinese sentence final particle (SFP) ne during CMC with a native speaker partner. The study investigated: (1) whether learners (as a group) developed their use of ne over time in the two CMC conditions, and (2) how individual learners changed their use of ne (if any) in the two conditions. The quantitative analysis (token and type frequency of ne) revealed that CMC itself did not promote learners’ use of ne. However, it promoted learners’ production of ne when data-driven instruction was incorporated into CMC. Supporting the quantitative findings, the qualitative analysis showed that one learner in the CMC with data-driven instruction outperformed his counterpart in the CMC without data-driven instruction group in the diverse use of ne.

This article investigates the syntax of the phrase-final focus particles kuphela and qha ‘only’ in Zulu and Xhosa (Nguni; Bantu). We show that kuphela’s and qha’s associations with a focused constituent respect the complex topography of information structure in Nguni and, like English only, a surface c-command requirement. However, unlike English only, the Zulu and Xhosa particles typically follow the focus associate they c-command, a fact that poses a serious challenge for Kayne’s (1994) antisymmetry theory. We demonstrate that the Nguni facts are incompatible with recent Linear Correspondence Axiom–inspired approaches to phrase-final particles in other languages and, after weighing the merits of several approaches, we conclude that kuphela is an adjunct and that syntax is only weakly antisymmetric: adjuncts are not subject to the LCA.
