Abstract This article argues that Emile Ollivier's 1991 novel, Passages, offers a representation of the migrant's body as a contact zone, as a space of entanglement of several processes of encounter and cultural productivity. The migrant's body will become the space where senses, cultural movements, memories, encounter each other, and the space of intersection of various forces. The body builds itself up at the intersection of the processes at stake, which each part of this article will focus on: movement, memory and solidarity between female migrants. In light of these processes, the migrant characters present in Ollivier's novel will be able to reclaim parts of their agency, previously lost in the wake of their displacements.

The work conducts laboratory tests on the rubber of the first group of GOST 8752-70 with the introduction of the metal components. The filler is introduced into the rubber mixture on laboratory rollers. Fine powders of copper (Cu), tin (Sn) and lead (Pb) are used as fillers. The dependences of the temperature in the contact zone of the sample and the body of revolution on the concentration of the filler and the dependence of wear on the concentration of the filler for the same loads and sliding speeds are obtained, the fillers that give the rubber the greatest wear resistance are revealed, and the rational amount of the filler is determined. The positive results of laboratory tests give grounds to recommend various equipment including aerospace equipment for use in sealing devices of hydraulic systems, rubber products with metal fillers in the indicated concentrations, which will extend their service life and increase their reliability

Beauty Care

This article analyses three issues: (i) female migration from northeastern states of India to two southern cities of India, Chennai and Bangalore, employed in the beauty-care sector; (ii) the broad socio-demographic characteristics of female migrants; and (iii) the role of social and cultural capital in inclusion and exclusion of these migrants in the two southern cities. The article discusses the migration process using an intersectionality approach and focuses on how women have become the central players in Migration Studies. The article explores the broad socio-demographic factors associated with their migrations and also examines the problems and harassment faced by the female migrants from northeastern states working in the beauty-care sector. The article advocates the analysis of migratory processes within the broader framework of gender, race, ethnicity and the changing labour market in urban regions of India.

Orthogonal Metal Cutting

In recent papers it has been suggested that over part of the tool-chip contact zone the chip does not slide but sticks to the tool, chip flow taking place by shear within the body of the chip. Sticking contact is inconsistent with steady state cutting and in this paper a slip-line field model of chip flow is presented which does not include sticking contact and which is consistent with the relevant experimental observations.

Bimaterial Interface Crack

A complete set of Comninou’s bimaterial interface crack-tip fields with and without friction in the contact zone (Comninou, 1977a,b) is given in terms of several arbitrary analytic functions. When the bimaterial becomes homogeneous, the complex function representation fully describes the crack-tip field for a cracked body under conditions of crack surface contact and slip, which can occur when the body is subjected to combined compression and shear loadings.

The relative actuation of the tool is considered, which makes it possible not to take into account the hard-to-determine technological coefficients depending on external conditions, as well as the physical, mechanical and technological properties of the processed material. This response is determined by the distribution of the relative sliding speeds and pressure in the contact zone of the tool and the work-piece, as well as the processing time, which are characterized by the geometric and kinematic parameters of the machine operating mechanism and processing modes. A phased simulation of the actuation process of the tool working surface is proposed: without oscillation of  the upper link and with its return-rotational  movement. According to this approach, at the first stage, the distribution of the relative sliding speeds and pressure in the contact zone of the grinding surfaces is calculated, and at the second stage, when determining the relative response at the points of the lower link (tool), the movement of these points from the areas of the contact zone with same values of the indicated quantities in the area with others is monitored. A mathematical model of the process of shaping a flat surface under conditions of free grinding of the body and counter-body is obtained, which establishes quantitative relationships between the machining modes and the shape of the treated surface and is a simulation numerical model, since it allows to obtain the distribution of relative triggering over the working surface of the tool for pre-selected time points.

Intraspecific Taxonomy

Background The application of molecular-phylogenetic approaches to taxonomy has had a dramatic effect on our understanding of the diversity of reptiles. These approaches have allowed researchers to reveal previously hidden lineages as well as taxonomic overestimation in morphologically plastic taxa. Slow worms, legless lizards of the genus Anguis (Squamata: Anguidae), were previously considered to comprise either one or two species, and morphology-based intraspecific taxonomy of Anguis fragilis remained controversial throughout the 20th century. After the discovery of deep genetic divergences within the genus, its taxonomy was reconsidered, and as a result, five extant species have been recognized. In order to better understand the patterns of their interspecific differentiation, here we studied phenotypic differences between the two most widespread of them—A. fragilis and A. colchica, and their putative hybrids across the contact zone of both species in Central Europe. Methods We used multivariate and univariate statistics and analyzed ten metric, eleven meristic, and six categorical phenotypic variables in material comprising a total of 326 individuals. We also genotyped individuals from the contact zone for one mitochondrial and two nuclear DNA fragments in order to delineate the distribution of individuals of hybrid and non-hybrid origin. The clines in morphological traits were studied using HZAR. Results We show that the two species are morphologically differentiated. Anguis fragilis has a less robust head, fewer scales covering the body, lower frequency of the external ear opening presence, lower frequency of separated prefrontal scales, higher frequency of prefrontal scales in contact with each other, and body coloration more similar to the juvenile coloration than A. colchica. Slow worms from the contact/hybrid zone are characterized by an intermediate morphology, with more similarities to A. fragilis than to A. colchica. Discussion None of the analyzed characters alone proved to be fully diagnostic, although more than 90% of all individuals could be successfully assigned to one or another species based on numbers of scales around the body. Our results indicate concordant, coincident, and steep clines in character states change. We present several hypotheses on the origin and evolutionary maintenance of the morphological divergence between both species and suggest that different evolutionary histories of the taxa rather than recently acting selection explain the observed morphological variation.

Abstract Comprehensive accounts of resource-rational attempts to maximise utility shouldn't ignore the demands of constructing utility representations. This can be onerous when, as in humans, there are many rewarding modalities. Another thing best not ignored is the processing demands of making functional activity out of the many degrees of freedom of a body. The target article is almost silent on both.

The simplicity of the developing nervous system of oligochaetes makes of it an excellent model for the study of the relationships between glia and neurons. In the present communication we describe the relationships between glia and neurons in the early periods of post-embryonic development in some species of oligochaetes.Tubifex tubifex (Mull. ) and Octolasium complanatum (Dugès) specimens starting from 0. 3 mm of body length were collected from laboratory cultures divided into three groups each group fixed separately by one of the following methods: (a) 4% glutaraldehyde and 1% acrolein fixation followed by osmium tetroxide, (b) TAPO technique, (c) ruthenium red method.Our observations concern the early period of the postembryonic development of the nervous system in oligochaetes. During this period neurons occupy fixed positions in the body the only observable change being the increase in volume of their perikaryons. Perikaryons of glial cells were located at some distance from neurons. Long cytoplasmic processes of glial cells tended to approach the neurons. The superimposed contours of glial cell processes designed from electron micrographs, taken at the same magnification, typical for five successive growth stages of the nervous system of Octolasium complanatum are shown in Fig. 1. Neuron is designed symbolically to facilitate the understanding of the kinetics of the growth process.
