Developing Grammatical Competence in Preschoolers

The article presents a theoretical review of relevant sources on the topic in question and, consequently, formulates the basic principles, obstacles and guidelines for developing grammatically correct speech in preschoolers. The article contains the author’s linguodidactic model for developing grammatically correct speech in preschoolers, as well as pedagogical conditions for its implementation: ensuring the interrelation between the perspective trends in learning, speech activity and speech experience of children; developing preschoolers’ grammatical skills using the specially developed methodology; teaching preschoolers the rules of morphology and methods of word-formation in language lessons; applying different effective forms and methods of organizing learning and speech activity for preschoolers. The article proves that the consideration and implementation of these factors have contributed to developing the suggested linguodidactic model for developing grammatically correct speech in preschoolers. It has also allowed one to create and practically implement it within the framework of the quasi-experimental educational process. The article indicates certain noticeable shifts in children with high and sufficient levels in all parts of the language being analyzed. It indicates that mastering the methods of word-formation as a means of enriching vocabulary helps preschoolers to learn the rules of form change and word-formation. Besides, the article has proved the effectiveness of targeted development of grammatically correct speech in preschoolers. The article may be of interest to university teachers and theorists in teaching East Slavic languages as native (at the beginning of their study) or as foreign.

Mechanical Properties as a Function of Casting Process of Aluminum–Silicon Alloy Matrix Composites

Applying aluminum composite in the defense, aerospace and automotive industries depends on how they behave during the elasto-plastic form change. In addition to the factors responsible for changing the form of the alloy, many other factors have an impact on the behavior of the composite form change. In this study, the effect of casting type on the mechanical properties of Al-Si nano composites has been investigated. Due to the proper distribution of reinforcing particles, tensile strength in compo casting sample in semi-solid state is higher than sand casting and squeeze casting. In all samples, the tensile strength of the heat-treated samples has increased by about 30%. Tensile strength in compo casting sample in semi-solid state was obtained with higher nano particle reinforcing particles, which can be explained by the fact that the percentage of elongation in micro samples was lower than that of nano composite samples.

Study on association solubilization and inhibition of scale in recirculating cooling water system under S-HGMF

The present study conducted an investigation on the effect of Superconducting-High Gradient Magnetic Field (S-HGMF) in the association solubilization of recirculating cooling water and the crystal form change of scale. The effects of magnetic flux density, flow rate and cycle-index on the solubility of scale-forming ions were investigated, and the effects of viscosity and surface tension on the molecular internal energy and order degree of circulating water were analyzed. The scale was ground and mixed with water and placed in a S-HGMF system to study the effect of S-HGMF on the crystal form change of CaCO3. The experimental results showed us that S-HGMF could increase the solubility of scale-forming ions. It could enhance the interaction between water molecules by increasing viscosity and reducing surface tension, so as to improve the stability of water quality, reduce ion precipitation, and achieve the effect of scale inhibition. At the same time, it could also change the crystal structure of CaCO3, promote the transformation of calcite to aragonite, and realize the purpose of scale inhibition. In a word, S-HGMF treatment can effectively solve the scaling problem of recirculating cooling water system, which provides a reference for scale inhibition of recirculating cooling water.

Cheboksary: toponymic sketches

The article is devoted to the problem of studying the history of origin, form change, etymology of the names of various geographical objects in the city of Cheboksary. The thesis is substantiated that, due to the change in the ethnic composition of the settlement, some part of geographic objects change their names, some remain unchanged, and some retaining some basis, begin to combine the specifics of several languages in onyms. On the basis of the reviewed materials on toponymy of the city of Cheboksary, the thesis is affirmed that onyms on the territory of the city of Cheboksary were formed on the basis of three ethno-linguistic sources: Turkic, Chuvash, Mari, and Russian.

Shape Indexes for Dieless Forming of the Elongated Forgings with Sharpened End by Tensile Drawing with Rupture

The criteria for the assessment of the form change in the process of direct profiling of workpieces , applying the stretching method with a rupture are developed, methods for their calculation are proposed with allowance for the volume of the redistributed metal and energy costs for deformation. The nature of the functional connection of these criteria of shape change assessment with the work of deformation is determined.

Polymetric Verse on Stage in Translation

The translators, actors, and directors working with the RSC on their 2004–5 Spanish Golden Age season faced a particular challenge in mounting four full English-language productions of plays written originally in a variety of Spanish verse forms. As script consultant for The Dog in the Manger and Pedro, the Great Pretender, the author discussed the plays’ polymetric structures with members of the company in rehearsal. The influence of the original Spanish versification could be seen, felt, and heard in all four of the English productions, whether or not the translator used verse, due to the structural and dramaturgical function of verse-form change. This chapter shows how a consultant working from the initial phases of translation through to stage production can make full use of the texts’ polymetry in the translation and performance.
