The Given

This paper is concerned with embodied processes of joint imagination in young children’s narrative interactions. Based on Karl Bühler’s notion of ‘deixis in the imagination’, it examines in detail how a 19-month-old German-speaking child, engaged in picture book reading with his mother, brings about different subtypes of deixis in the imagination by either ‘displacing’ what is absent into the given order of perception (e.g. by using the hand as a token for an object) or displacing his origo to an imagined space (e.g. by kinaesthetically aligning his body with an imagined body and animating his movements). Drawing on multimodal analysis and the concept of layering in interaction, the study analyses the ways in which the picture book as well as deictic, depictive, vocal and lexical resources are coordinated to evoke a narrative space, co-enact the storybook character’s experiences and produce reciprocal affect displays. Findings demonstrate that different types of displacement are in play quite early in childhood; displacements in the dimension of space and person are produced through layerings of spaces, voices and bodies.

The energy resolution, i.e. the precision with which the energy of a showering particle can be measured, is one of the most important characteristics of a calorimeter. This resolution is determined by fluctuations in the absorption and signal formation processes. In this chapter, the different types of fluctuations that may play a role are examined, and their relative practical importance is addressed. Sources of fluctuations include fluctuations in the number of signal quanta, sampling fluctuations, fluctuations in shower leakage, as well as a variety of instrumental effects. Since the energy dependence of the different types of fluctuations is not the same, different types of fluctuations may dominate the energy resolution at low and and at high energies. An important type of fluctuations is part of the non-compensation phenomena. It concerns fluctuations in the strength of the electromagnetic component of hadronic showers. The effects of these fluctuations, which typically dominate the energy resolution for hadron and jet detection, are examined in detail. In sampling calorimeters, one particular shower particle may sometimes have catastrophic effects on the calorimeter performance. Several examples of such cases are discussed.

Objective: To compare the characteristics of hydraulic potential in worn steel pipes with internal deposits subjected to cleaning by mechanical and chemical methods. Methods: Calculated dependencies are used for hydraulic calculation of new metal pipes and pipes with internal deposits. Results: A calculated dependence was obtained to determine the value of the inner diameter of pipes with any thickness of the layer of internal deposits. The concept of an efficient pipeline is introduced and a comparison made of the values of head losses in new pipes and in pipes with internal deposits. A specific practical example is considered. For the given example, compare the values of energy consumption of pumping equipment for two methods of cleaning the inner surface of pipes. Measures are indicated to ensure the efficiency of operation of water supply networks. Practical importance: It is shown that the chemical method of technical regulation of the hydraulic characteristics of new steel pipes provides an extension of the period of their further use.

The Given

Abstract The telicity behavior of degree achievements has been a puzzling problem to many linguists. The most successful and currently standard theory (Kennedy & Levin 2008) treats them as degree expressions lexicalizing different types of scales, which in turn influence the resulting evaluative or non-evaluative interpretation. While it may account for English, this theory does not hold up cross-linguistically. We challenge the scalar theory with new Slavic data and show that verbal prefixes influence the (non-)evaluative interpretation of degree achievements more than their underlying scales do. This proposal is formalised as an addition of two type shifters, morphosyntactically realised as prefixes, which, in result, have an evaluative/non-evaluative effect on the given degree achievement.

Abstract The management of given and new information is one of the key components of accomplishing coherence in oral discourse, which is claimed to be a problematic area for language learners (Celce-Murcia, Dörnyei, and Thurrell 1995: 14). Research on discourse intonation proposes that instead of the given/new dichotomy, givenness should be viewed as a continuum, with different types of accessibility (Baumann & Grice 2006). Moreover, Prince (1992) previously categorized information structure into Hearer-old/Hearer-new and Discourse-old/Discourse-new information. There is consensus on the fact that focus or prominence associated with new information is marked with nuclear pitch accent, and its main acoustic cue, fundamental frequency (f0) (Ward & Birner 2001: 120). Non-native intonation has been reported to display numerous differences in f0 range and patterns compared to native speech (Wennerstrom 1994; Baker 2010). This study is an attempt to address the issue of marking information structure in existential there sentences by means of f0 in non-native spontaneous speech. Data originates from task-based interactions in the Wildcat Corpus of Native- and Foreign-Accented English (Van Engen et al. 2010). This paper examines two issues: (1) information structure in relation to the notions of givenness and different types of accessibility (Baumann & Grice 2006) and to Prince’s (1992) multidimensional taxonomy and (2) the use of f0 peaks to mark the prominence of new information. Several differences were measured among native speakers regarding the use of f0, sentence type, and complexity.

Pectin Substances

Viscosity is one of the characteristic properties of pectin substances, as well as other lyophilic colloids. Pectin molecules are easily associated with each other or with large molecules of related substances. This article contains the results of the study of dynamic viscosity, internal friction, thixotropic index of aqueous solutions (1 % and 4%) of various types of pectin substances and their combinations. The article presents the results of the study of the influence of different types of pectin substances and their combinations on the dynamic viscosity of pectin solutions and their internal friction. The analysis of values of dynamic viscosity and friction force depending on the type of pectin substances and their combinations is given. It is established that in cases where information on dissipative processes in pectin structures at low speeds and shear loads is required, it is necessary to rely on data on internal friction, in others - on the given information on their viscosity. The thixotropic index is calculated. It is established that the internal friction in pectin solutions and their dynamic viscosity depend on the type of pectin substances and their combinations. In pectin solutions, the internal friction is maximum for Apple pectin, and the dynamic viscosity – for a combination of citrus pectins with beet. When combining pectins, both indicators are most important for the combination of citrus with beet. The obtained data on the viscosity, internal friction and thixotropic index of solutions of different types and combinations of pectins make it possible to regulate the rheological properties of food systems with the addition of pectin substances.

The need of typewriting skill is ever increasing in our lives. The prevalence of personal computers and mobile devices has transformed the way people communicate with each other. Although many different types of human interfaces have been introduced over the decades, the dominant form of computer interface remains to be that of typing on a keyboard. [...] Whilst typing has become one of the common everyday skills within the last two decades, experimental psychologists have been studying it as a research subject for more than a hundred years. [...] Apart from its practical importance in the modern lifestyle, the act of typing involves the right amount of complexity as well as well-defined and measurable actions. These features of typewriting makes it an ideal testbed to gain our understanding of the control and acquisition of complex skills. This review article first presents a brief overview of the classic studies of typewriting skill in the early 20th century, discusses the developments that took place after the mid-20th century, and concludes with the current status and issues that remain for future investigations in the 21st century.

The Euclidean plane and Euclidean space themselves do not contain imaginary elements by definition, but are inextricably linked with them through special cases, and this leads to the need to propagate geometry into the area of imaginary values. Such propagation, that is adding a plane or space, a field of imaginary coordinates to the field of real coordinates leads to various variants of spaces of different dimensions, depending on the given axiomatics. Earlier, in a number of papers, were shown examples for solving some urgent problems of geometry using imaginary geometric images [2, 9, 11, 13, 15]. In this paper are considered constructions of orthogonal and diametrical positions of circles on a complex plane. A generalization has been made of the proposition about a circle on the complex plane orthogonally intersecting three given spheres on the proposition about a sphere in the complex space orthogonally intersecting four given spheres. Studies have shown that the diametrical position of circles on the Euclidean E-plane is an attribute of the orthogonal position of the circles’ imaginary components on the pseudo-Euclidean M-plane. Real, imaginary and degenerated to a point circles have been involved in structures and considered, have been demonstrated these circles’ forms, properties and attributes of their orthogonal position. Has been presented the construction of radical axes and a radical center for circles of the same and different types. A propagation of 2D mutual orthogonal position of circles on 3D spheres has been made. In figures, dashed lines indicate imaginary elements.
