Study of spatial-time inhomogeneity of serrated plastic flow Al-Mg alloy: using DIC-technique

The aim of the present paper is the investigation of temporal instabilities and spatial localizationdue to the Lüders behavior, the Portevin–Le Chatelier effect and the shoulder or necking effect during uniaxialtension tests of aluminum-magnesium alloy. This paper presents the brief description of the test procedure andexperimental results of carrying out research by the combined use of a servo-hydraulic biaxial test systemInstron 8850 and a non-contact 3-D digital image correlation measurement system Vic-3D. The digital imagecorrelation is a highly effective computer-vision-based technique, which provides estimation of thedisplacement and strain fields on specimen surface by matching the reference subsets in the undeformed image(before loading) with the target subsets in the deformed images (captured during test). The evolution ofinhomogeneous axial strain and axial strain rate fields has been illustrated for each stage of material’sdeformation. To estimate the kinematics of serrated or jerky flow due to the strain bands propagation, the strainversus time curves and strain diagrams are given here. The experimental results show the recurrence in thestrain distribution leveling along the specimen gauge. The changing between the macroscopic localization of theplastic flow, namely the running of the Lüders and PLC bands and the recovery of strain field homogeneity, hasbeen observed

Role of the laws of psychology in personal and implementation of professional doctor

The article raised the issue of the relationship between two scientific fields – medicine and psychology. The authors, considering the demands of the profession and the individual doctor, formulate the laws of psychology that operate in the power of the psychological characteristics of the medical profession, as it relates to the system «man – man»Ставится проблема взаимосвязи двух научных областей – психологии и медицины. Авторы, учитывая требования профессии к деятельности и личности врача, формулируют законы психологии, во многом определяющие качество, результативность деятельности и личностное развитие врача, чья профессия относится к системе «человек – человек

Migration safety in education: Adaptation of migrant students to conditions at higher educational establishments

The topicality of the problem under study stems from the changed geopolitical and socioeconomic conditions in Russia, which resulted in uncontrollable international and migration processes, changes in the ethnic composition of territories, worsening of ethnic and social relations of migrants and members of the society receiving them, search for educational paradigms complying with new conditions of the country's development. The aim of the research is to determine specific features relating to adaptation of migrant students to conditions at higher educational establishments and to draw up a programme of social, psychological and pedagogical activities to adapt migrant students to conditions at higher educational establishments. The leading research method is an experimental one, which enables us to fully consider the problem of adapting migrant students to conditions at higher educational establishments. The article outlines a system of social, psychological and pedagogical help to migrant students needed to optimise a process of their adaptation to an educational environment. The programme is aimed at creating social, psychological and pedagogical conditions for the efficient interaction of all members of an educational process, as well as full fulfillment of a person in conditions of a poly-cultural educational process. Teachers, curators, heads of subdivision and administrations of higher educational establishments may find the materials of the article useful. © Authors
