Formation of singularities on the surface of a liquid metal in a strong electric field

The nonlinear dynamics of the free surface of an ideal conducting liquid in a strong external electric field is studied. It is establish that the equations of motion for such a liquid can be solved in the approximation in which the surface deviates from a plane by small angles. This makes it possible to show that on an initially smooth surface for almost any initial conditions points with an infinite curvature corresponding to branch points of the root type can form in a finite time.Comment: 14 page

Piezomagnetism and Stress Induced Paramagnetic Meissner Effect in Mechanically Loaded High-T_c Granular Superconductors

Two novel phenomena in a weakly coupled granular superconductor under an applied stress are predicted which are based on recently suggested piezophase effect (a macroscopic quantum analog of the piezoelectric effect) in mechanically loaded grain boundary Josephson junctions. Namely, we consider the existence of stress induced paramagnetic moment in zero applied magnetic field (piezomagnetism) and its influence on a low-field magnetization (leading to a mechanically induced paramagnetic Meissner effect). The conditions under which these two effects can be experimentally measured in high-T_$ granular superconductors are discussed.Comment: 4 pages (REVTEX, epsf.sty), 2 PS figure

Point contact spectroscopy of the electron-doped cuprate superconductor Pr{2-x}Ce{x}CuO4: The dependence of conductance-voltage spectra on cerium doping, barrier strength and magnetic field

We present conductance-voltage (G-V) data for point contact junctions between a normal metal and the electron doped cuprate superconductor Pr{2-x}Ce{x}CuO4 (PCCO). We observe a zero bias conductance peak (ZBCP) for the under-doped composition of this cuprate (x=0.13) which is consistent with d-wave pairing symmetry. For optimally-doped (x=0.15) and over-doped (x=0.17) PCCO, we find that the G-V characteristics indicate the presence of an order parameter without nodes. We investigate this further by obtaining point contact spectroscopy data for different barrier strengths and as a function of magnetic field.Comment: 13 pages, 9 figure

Innovative pedagogical forms of medical education of students of a medical university: the experience of the department of psychology and pedagogy

An experiment of the Department of Psychology and Pedagogy of Ural State Medical University on realization of innovative pedagogical forms of education of students of a medical school is exposed in this article. Such innovative pedagogical forms as story-role modelling of situations, art-therapeutic classes, mediation techniques of conflict management and project activities are presented and described. These pedagogical forms are relevant in the conditions of medical education and are focused on formation of common cultural and professional competences.В статье показан опыт кафедры психологии и педагогики УГМУ по реализации инновационных педагогических форм обучения студентов медицинского вуза. Представлено краткое описание таких форм практических занятий как сюжетно-ролевое моделирование ситуаций, арт-терапевтические занятия, медиативные формы управления конфликтами, проектная деятельность. Эти педагогические формы доказали эффективность при реализации концепции практико-ориентированного медицинского образования и нацелены на формирование как общекультурных, так и общепрофессиональных компетенций будущих медицинских работников

Assessment of practical skills in primary accreditation of the specialist on the methody of «simulated patient»: the results of the piloting station «history in the primary outpatient medical visit”

The description and results of realization of the pilot project within the second stage of primary accreditation of specialists in 2017 (specialty «Medical job») are briefly presented. The pilot project’s goal is to assess the real opportunities of realization examination of the effective communicative skills to with patients during the collection of complaints and anamnesis on a primary outpatient medical appointment. The pilot station was tested in two universities: the First Moscow State Medical University and the Urals State Medical University, Yekaterinburg.Кратко представлены описание и результаты реализации пилотного проекта в рамках второго этапа первичной аккредитации специалистов в 2017 году (специальность «Лечебное дело»). Цель пилота — оценка возможностей реализации экзамена по владению практическими навыками эффективного общения с пациентами при сборе жалоб и анамнеза на первичном амбулаторном врачебном приеме. Пилотная станция проходила апробацию в двух вузах: Первом Московском государственном медицинском университете им. И.М. Сеченова и Уральском государственном медицинском университете, г. Екатеринбург
