Relative clauses (RCs) are considered islands for extraction, yet acceptable cases of overt extraction from RCs have been attested over the years in a variety of languages: Danish, Swedish, Norwegian, Japanese, Hebrew, English, Italian, Spanish, French, and also in Lebanese Arabic and Mandarin Chinese, where covert extraction from an RC is observed. The possibility for extraction has often been presented as evidence against a syntactic theory of locality, and in favor of constraints defined in terms of information structure, or processing limitations and constraints on working memory. Another possibility, still hardly explored, is that locality is determined syntactically, combined with a more fine-grained structure for RCs and a theory of how extraction from this structure interacts with the theory of locality. I argue in favor of the latter approach. I assume the structural ambiguity of RCs and argue that while externally headed RCs do block extraction, extraction is possible, under certain conditions, from a raising RC, and is formally similar to extraction from an embedded interrogative.

In this study, we examined eye movements and comprehension in sentences containing a relative clause. To date, few studies have focused on syntactic processing in dyslexia and so one goal of the study is to contribute to this gap in the experimental literature. A second goal is to contribute to theoretical psycholinguistic debate concerning the cause and the location of the processing difficulty associated with object-relative clauses. We compared dyslexic readers (n = 50) to a group of non-dyslexic controls (n = 50). We also assessed two key individual differences variables (working memory and verbal intelligence), which have been theorised to impact reading times and comprehension of subject- and object-relative clauses. The results showed that dyslexics and controls had similar comprehension accuracy. However, reading times showed participants with dyslexia spent significantly longer reading the sentences compared to controls (i.e., a main effect of dyslexia). In general, sentence type did not interact with dyslexia status. With respect to individual differences and the theoretical debate, we found that processing difficulty between the subject and object relatives was no longer significant when individual differences in working memory were controlled. Thus, our findings support theories, which assume that working memory demands are responsible for the processing difficulty incurred by (1) individuals with dyslexia and (2) object-relative clauses as compared to subject relative clauses.

This paper presents an analysis of the pied-piping phenomenon in Russian relative clauses in the 18th–19th centuries and in present-day Russian. As is well-known, the relative pronoun kotoryj ‘which’ tended to precede its pied-piped head in the 18th–19th centuries and tends to follow it today. This difference, which has mainly been investigated for relativization on genitives, is demonstrated to be valid for a number of heterogeneous syntactic contexts. I propose to account for the syntactic shift undergone by the Russian relative clauses since the 19th century in terms of a more general shift in information structure: I argue that the linear order of the relative pronoun and its head that was acceptable in Russian two centuries ago, is now in contradiction with the modern inventory of felicitous information structure patterns.

Abstract In this paper, we propose the implementation of a full-fledged feature-based lexicalist syntactic theory as a way to represent the possible configurations of features in the learner’s interlanguage and formalize a theory of acquisition based in feature reassembly. We describe gender agreement pronominal coindexation in Spanish using Head-driven Phrase Structure Grammar (HPSG) and use it to analyze the results of a self-paced reading test with L1 and L2 speakers. We find that the specification of the gender feature value at the syntactic level in epicene antecedents facilitates pronominal resolution in L1 Spanish speakers. Conversely, there is a cognitive cost when the gender feature is underspecified at the syntactic level in common gender antecedents; this cost is not found among L2 speakers. The detailed descriptions in terms of feature specification in the HPSG framework allow us to observe differences between the L1 and L2 grammars in fine-grained detail and represent optionality at the lexical level.

Fracture toughness (K1C) of medium carbon steel (0.5% C) has been determined by round notched tensile specimen. Two notch diameters (5.6mm and 4.2mm) and three notch angles (α) namely 45°, 60° and 75° have been used to observe the effect of notch diameters and notch angle on fracture toughness of the steel. By heat treatment the microstructure of the steel is also varied and its effect on the fracture toughness is also observed. It has been found that fine grained structure improves fracture toughness. Lower notch diameter and higher notch angle show higher value of K1C.

Fine Grained Structure

The principles of jet electrodeposition orientated by rapid prototyping were introduced. The nanocrystalline nickel parts with simple shape were fabricated using jet electrodeposition. The microstructure and phase transformation of nanocrystalline nickel were observed under the scanning microscope and X-ray diffraction instrument. The results show that the jet electrodeposition can greatly enhance the limited current density, fine crystalline particles and improve deposition quality. The nickel parts prepared by jet electrodeposition own a fine-grained structure (average grain size 25.6nm) with a smooth surface and high dimensional accuracy under the optimum processing parameters.

The study considers the formation of the structure, texture, and hardness of hot extruded tube of titanium alloy PT-1M. It is shown that hot extrusion at 840 °C, which is higher than the α-phase recrystallization temperature, results to the development of dynamic and primary recrystallization processes and ensures the formation of homogeneous and fine-grained structure through-out the cross section with a two-component tangential texture (0001)TD<100>ED+(0001)TD<110>ED (TD – tangential direction, ED – extrusion direction) and hardness of 155 HV. It has been established that a higher cooling rate of the surface areas of the tube after extrusion results to a less active development of recrystallization processes, which lead to the formation of a finer granular structure near the outer surface. This weakens recrystallization component of (0001)TD<110>ED, compared to other areas of the tube.

In the present study, a mixture of powders (87.9 at.% Ni, 12 at.% Al, 0.1 at.% B) was used as the initial material to produce sintered Ni3Al + B alloy. Spark Plasma Sintering (SPS) method was used to compact the powder. The powder mixtures were previously prepared in two ways: mixing the initial powders in a mortar (М1) and mechanical activation (М2). The microstructure was observed using optical microscope (OM). The addition of small amount of boron to the initial mixture of nickel and aluminum improves the density of the sintered Ni3Al intermetallic compound (98.8%). The results of density, bending and microhardness tests showed, that the provisional three-minute mechanical activation improves almost all properties of the sintered material. The compact obtained by SPS by M2 contributes to the formation of a homogeneous fine-grained structure of the material. It leads to further increase in flexural bending strength up to 2200 MPa. This value is almost 8 times the strength of the intermetallic Ni3Al stoichiometric composition obtained by SPS.
