This paper promotes the hypothesis that central grammatical categories must be analysed as pragmatic rather than semantic entities, in order to explain their seemingly redundant typological distribution. A case is made of the relatively complex English past tense system versus the single Russian past tense, and it is shown how the distinctions within the former system can be analysed in terms o...

Abstract A demonstration plant designed for methanol synthesis with steel mill gases was operated continuously the first time over a period of 5 weeks. The reactor represents single tube typical dimensions an industrial bundle boiling water cooling jacket and is incorporated into full loop unreacted gases. Temperature profile along axis gas composition in recycle stream are measured online. In ...

BACKGROUND Numerous designs are used to the treatment of Early Onset Scoliosis. For example, a Thoraco-Lumbo-Sacral Orthosis (TLSO) is constructed using Polyethylene (PE). In addition, a series of castings has been implemented using cast material (3M, BSN Medical). The cast material has some significant advantages over the PE design including: growth preserving, improved compliance, decreased i...

Hybrid excitation synchronous motor has the advantages of uniform and adjustable electromagnetic field, wide speed range high power density. It broad application prospects in new energy electric vehicles, wind generation other fields. This paper introduces basic structure hybrid with modular stator, analyzes operation principle motor. The cooling water-cooled plate is designed, effects thicknes...

Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...

The paper presents the background to expressions adopted in new Eurocode 8—3 for jacketed reinforced concrete columns. These are based on commonly concept of monolithicity factors (ratios resistance section that an identical monolithic one). derived here two ways: (i) by fitting experimental results columns and (ii) extended parametric study substandard (R/C) members were retrofitted adding R/C...

An orthogonal cocyclic framework of the block-wise inverse Jacket transform (BIJT) is proposed over the finite field. Instead of the conventional block-wise inverse Jacket matrix (BIJM), we investigate the cocyclic block-wise inverse Jacket matrix (CBIJM), where the high-order CBIJM can be factorized into the low-order sparse CBIJMs with a successive block architecture. It has a recursive fashi...

In this paper, we propose a new construction method for a novel class of parametric reciprocal-orthogonal jacket transform (PROJT) having 4N parameters for a sequence length N = 2r+1 that is a power of two, based on the reciprocal-orthogonal parametric (ROP) transform and block diagonal matrices. It is shown that the inverse transform of the proposed PROJT is conveniently obtained by the recipr...
