This paper adopts a constructional approach to grammatical structure (Goldberg 1995; 2006) and a corpus-based method for investigating pairs of semantically similar constructions and the lexemes that occur in them. The method, referred to as distinctive-collexeme analysis (Gries and Stefanowitsch 2004a), is used to determine which of the lexemes occurring in two constructions are most distinctive for either of them. On the basis of the case study concerning the imminent-NOUNconstruction versus the impending-NOUN construction, the paper demonstrates that one construction attracts some nouns more strongly than the other does. Moreover, the results of the distinctive-collexeme analysis of this pair of constructions reveal that there are clearly distinctive collexemes for each of the two constructions, and that the frame-constructional semantics is a contributing factor in the selection between these two patterns.

The electrostatic impulse method is an established method for producing microbeads or capsules. Such particles have found application in biomedical engineering and biotechnology. The geometric properties of the droplets – constituting precursors of microbeads and capsules – can be precisely controlled by adjusting the geometry of the nozzle system, the physical properties and the flow rate of the fluids involved, as well as the parameters of the electrostatic impulse. In this work, a method of mathematical modeling of the droplet generation process using the electrostatic impulse method in a single nozzle system is presented. The developed mathematical model is an extension of the standard Volume of Fluid (VOF) model by addition of the effect of the electric field on the fluid flow. The model was implemented into the OpenFOAM toolkit for computational fluid dynamics (CFD). The performed CFD simulation results showed good agreement with experimental data. As a result, the influence of all process parameters on the droplet generation process was studied. The most significant change in droplet generation was caused by changing the electrostatic impulse strength. The presented modeling method can be used for optimization of process design and for studying the mechanisms of droplet generation. It can be extended to describe multi nozzle systems used for one-step microcapsule production.
