Self-assembly process under a solid-state reaction of β-Si3N4/austenitic stainless-steel composites: stirring conditions and material texture

In the self-assembly process of β-Si3N4 (SN)/316L stainless-steel (SUS316L) composite materials tailored via sintering of powder mixtures, the formation of a SN agglomerate resulting from condensation–dispersion reactions during the stirring of SN/SUS316L was found to play an important role in improving the thermal conductivity. Moreover, the obtained SN secondary particle groups connected to form a network through diffusion-limited aggregation. In particular, it was shown that the sample prepared at the milling speed of 150 r/min has a similar particle group area (about 1.38 μm2) to that at 120 r/min, but a higher κ (increased from 9.5 W m−1 K−1 to 11.5 W m−1 K−1). To quantitatively evaluate the microstructural morphology of the texture of the self-assembled composite material, global parameters τ( q) and D q and local parameters α( q) and f( α) were determined via multifractal analysis. These characteristics of the anisotropy, dispersion, and cohesiveness of the particle network in the material texture could be analyzed together with the capacity dimension D0, information dimension D1 (configuration entropy), correlation dimension D2, and α( q) (related to internal energy). The results suggest that α( q) reflects the differences in the cohesion of the additive particle agglomeration that constitutes the self-assembly process under the solid-state reaction.

Additive particles, prosodic structure and focus sensitivity in Hungarian

The main aim of this article is to investigate the prosody-information structure interface in the analysis of the Hungarian additive particle is ‘also, too’. We present a prosodic study of narratives, collected through guided elicitation, and provide a prosodic basis for a focus-based analysis of is. Standard formal semantic approaches to the interpretation of additive particles regard additive particles as focus sensitive, hence the associate of the particle is focal and the focus interpretation (in terms of alternatives) is a significant part in its semantics. This view is considered crosslinguistically valid, although the discussion mostly concerns English. In Hungarian, the focus sensitivity of the additive particle is not directly transparent and needs more elaboration. In the relevant literature, the issue of focus marking with respect to the additive particle is has been insufficiently studied or merely stipulated. In this article, we argue for the importance of a more elaborate study of the prosody-information structure interface in the analysis of Hungarian additive particles. Accordingly, we provide data and its analysis to support our core argument and claims. Our study contributes to the overall understanding and analysis of is and to the general claims about focus marking and focus types in Hungarian. We aim to complement the standard semantic analyses by providing a prosodic analysis supporting the focus-sensitive analysis of is instead of merely stipulating an association with focus. On a more general level, we show that the various readings of additive particles can be explained by taking the prosodic patterns of the relevant constructions into account.

Added Alternatives in Spoken Interaction: A Corpus Study on German Auch

Particles such as German auch (‘also’) establish an additive relation between expressions in their scope (added constituent, AC) and context alternatives against the background of shared information (common denominator). In spoken interaction, however, explicit alternatives are not necessarily present and expressions can be construed as alternatives against different variants of a common denominator. It is the aim of the present paper to investigate to what extent the presence of alternatives influences the construction of utterances containing an additive particle. This is particularly relevant for German, where speakers can choose between an unstressed and stressed version of auch. We ask whether properties of the alternatives and their common denominators influence the choice to use stressed or unstressed auch. In a corpus study on spoken language, we classified the versions of auch, the particles AC, the alternatives in the preceding context and their common denominator. The results show that the speaker’s choice is influenced by the relation of the utterance to context alternatives. Specifically, the degree of explicitness of alternatives, the number of alternatives, and the degree of abstractness of the common denominator influence the continuation of the discourse, measured by the preference for one of the two variants of the particle auch.

Simulating semantic change: A methodological note

The current work discusses the Human Diachronic Simulation Paradigm (HUDSPA), a method to experimentally probe into historical meaning change set up to (i) scan for configurations similar to attested alterations of meaning but in (typically, but not necessarily, related) languages or varieties which did not actualize the change(s) under investigations; (ii) measure the reactions of native speakers in order to ascertain the verisimilitude as well as the particular semantic and pragmatic properties of the items scrutinized. Specifically, the present paper discusses the relative propensity of a particularizer (German eben) to be interpreted with comparatively high confidence as a scalar additive particle such as even and of a concessive item like English though to be interpreted similar to a modal particle along the lines of German doch.

Seepage Characteristics of Slurry with Particle Additives in the High-Permeability Sand Layer

In the process of the slurry shield construction, the formation of the filter cake is the key to maintain the stability of the excavation face. In high-permeability formation, ordinary pure bentonite slurry is easy to pass through the formation void. Therefore, it is necessary to study the slurry permeability characteristics of the high-permeability sand layer. For the purpose of researching the permeability characteristics of slurry in sandy formation, this paper studies the influence of slurry viscosity on the formation of the filter cake in high-permeability formation under different pressure gradients by the slurry permeability test. The effect of additive particle size on the film-forming gain was studied by adding additives with different particle sizes into pure bentonite slurries with different viscosities. This paper presents a method to determine the optimum slurry viscosity and particle size for high-permeability formation so as to guide the slurry shield construction in high-permeability formation.

The effect of additive particle size on the anti-corrosion behavior of PU coating

Purpose The purpose of this study is to investigate the influence of additive particle size on the anti-corrosion behaviors of polyurethane (PU) coating. Design/methodology/approach The graphite (Gr) and poly-graphite (PGr) were used as large size additive and small size additive, respectively. The immersion test and electrochemical test were used to study the corrosion behaviors. Findings In the immersion test, the surface of the bare steel sample was corroded uniformly. However, for the steel samples with coatings, the surfaces were corroded locally. This phenomenon showed that the coating can isolate artificial sea-water and samples and then decreased the corrosion rate. Furthermore, the most severe corrosion was observed on the sample with the Gr/PU coating compared with other anti-corrosion coatings. The results of the electrochemical measurements indicated that the corrosion rate of the sample with PGr/PU coating was approximately two times lower than that of the sample with the Gr/PU coating and the sample with PGr/PU coating was hardest to be corroded. Originality/value To have a more objective and direct recognition of the particle size effect on the coating quality.

Free Choice-Free Relative Clauses of the Type “Indiferent + Wh-” in Romanian

Free Choice-Free Relative Clauses of the Type “Indiferent + Wh-” in Romanian. The hypothesis of this paper is that the inventory of the free choice items in Romanian can be extended by including, along with the indefinites and the wh- compounds with ori-, a complex structure consisting of the adverb indiferent (‘regardless’) plus a wh-item. Based on syntactic tests, the paper suggests a line of interpretation according to which two patterns of relative clauses are possible with indiferent followed by a wh-item: (i) a headed relative clause licenced by a PP (de) which is syntactically required by the adverb indiferent, and (ii) a pattern in which the preposition de is covert, and the adverb functions as a quantifier that takes scope over the relative node; the clause is adjoined to the matrix together with the adverbial. We are dealing, therefore, with a free relative endowed with the free choice semantics of the adverb. In contexts of this type, the adverb indiferent seems to act like an additive particle to the wh-items, in a semantically similar way in which the prefix ori- contributes to the meaning of the complex free choice wh-words in Romanian. This hypothesis is also supported by the fact that the group formed by indiferent + wh-items is also occurrent in constructions with the ellipsis of the VP in the relative clause, a fact that strengthens the parallelism with the free choice items available in Romanian.

Additive particle uses in Hungarian

In this paper, we investigate empirical data that raise challenging issues with respect to focus sensitivity of the Hungarian additive particle is ‘also, too’. In Hungarian, the additive particle is attached to a constituent, and the is-phrase cannot occupy the structural focus position. This raises the issue how to capture the focus sensitivity of is. We propose a primarily pragmatic, context-based analysis of the Hungarian additive particle, where the particle associates with the pragmatic focus (Lambrecht 1994) determined on basis of the immediate question under discussion (Roberts 2012). Important evidence for this claim is that the Hungarian additive particle can take different semantic associates, corresponding to the pragmatic focus of the sentence. After discussing the Hungarian data, we will present the analysis in the framework of Role and Reference Grammar (Van Valin & LaPolla 1997; Van Valin 2005). To capture Hungarian and English data in a uniform way, important extensions of the framework will be proposed.
