A Two-Dimensional MagnetoHydrodynamics Scheme for General Unstructured Grids

We report a new finite-difference scheme for two-dimensional magnetohydrodynamics (MHD) simulations, with and without rotation, in unstructured grids with quadrilateral cells. The new scheme is implemented within the code VULCAN/2D, which already includes radiation-hydrodynamics in various approximations and can be used with arbitrarily moving meshes (ALE). The MHD scheme, which consists of cell-centered magnetic field variables, preserves the nodal finite difference representation of div(\bB) by construction, and therefore any initially divergence-free field remains divergence-free through the simulation. In this paper, we describe the new scheme in detail and present comparisons of VULCAN/2D results with those of the code ZEUS/2D for several one-dimensional and two-dimensional test problems. The code now enables two-dimensional simulations of the collapse and explosion of the rotating, magnetic cores of massive stars. Moreover, it can be used to simulate the very wide variety of astrophysical problems for which multi-D radiation-magnetohydrodynamics (RMHD) is relevant.Comment: 22 pages, including 11 figures; Accepted to the Astrophysical Journal.

Leadership as a Control Method in the Period of Changes

The article provides an overview of the conceptual understanding of leadership in social management development. Authors differentiate between leadership comprehensions. Particular attention has been paid to value-based theories and modern 21st century leadership models, where the world is understood as dynamic, constantly changing and risky. Leadership is considered as a process of effective modern organization management

Problemas de gestión empresarial en la actual situación de crisis

El documento examina los problemas que enfrentan las empresas en el sector real de la economía. Estos problemas no son nuevos; se han debatido en la comunidad científica durante una década,pero en la realidad actual, cuando toda la economía mundial vive en una pandemia, estos problemas se han agravado y requieren un enfoque serio y equilibrado para su solución. Todas las crisis económicas se reflejan principalmente en la actividad inversora. Por eso es necesario resaltar la seguridad económica en el campo de asegurar la efectividad de las inversiones presupuestarias. Es en esta área donde se observan la mayor parte de las violaciones y, en ocasiones, los delitos en el área financiera y de inversión de las relaciones de todos los participantes en los procesos comerciales de la economía. En términos metodológicos generales, el artículo fundamenta y revela una propuesta de organización de un sistema de análisis indicativo y regulación de los volúmenes de producción y actividades productivas y económicas de las empresas y organizaciones del sector real de la economía, como herramienta organizativa para resolver situaciones de crisis en la economía. Se abordan los factores, tanto externos como internos, que causaron el actual estado insatisfactorio de la economía rusa. En un plan concreto, se presentan las propuestas del autor sobre las direcciones y formas de superar los fenómenos de crisis actuales en la economía rus

Linguistic Characterization of Text on Environmental Topics

The article discusses the structural and semantic features of a regional newspaper text on environmental topics. The material contains 30 texts from the socio-political newspaper “Rech” of the city of Cherepovets, Vologda Oblast, published during 2017 - the Year of Ecology in Russia. It is shown that the newspaper text on environmental topics has the structure of an inverted pyramid, when important information is presented at the beginning of the article, and detailing is presented in the second part; the photographs accompanying the texts have a different visual-grammatical structure and can be interpreted as one-part and two-part sentences. In the semantic aspect, it is revealed that a larger number of contextual synonymous pairs than sets are formed; gradual antonyms are used; lexical units are included that fix the anthropocentric model of the interaction of man and nature. It is identified that there is a two-way interaction between the environmental event and the text: the event is the basis for creating the text, and vice versa, a newspaper text covering an environmental problem may precede one event or another. It is indicated that the newspaper text on environmental topics is characterized by a homogeneous presentation of the material, anthropocentricity and polyphonicity; softening the presentation of problematic information is achieved through the use of literary synonyms, gradual antonyms and relevant illustrations

Problemas de gestión empresarial en la actual situación de crisis

The paper examines the problems faced by enterprises in the real sector of the economy. These problems are not new; they have been discussed in the scientific community for a decade, but in today's realities, when the entire world economy lives in a pandemic, these problems have become aggravated and require a serious, balanced approach to their solution. All economic crises are primarily reflected in investment activity. That is why it is necessary to highlight economic security to ensure the effectiveness of budget investments. In this area, the bulk of violations and sometimes crimes are observed in the financial and investment area of relations of all participants in business processes in the economy. In general methodological terms, the article substantiates and reveals a proposal for organizing a system of indicative analysis and regulation of production volumes and production and economic activities of enterprises and organizations of the real sector of the economy as an organizational tool for resolving crisis situations in the economy. Both external and internal factors are touched upon, which caused the current unsatisfactory state of the Russian economy. In a concrete plan, the author's proposals on the directions and ways of overcoming the current crisis phenomena in the Russian economy are presented.El documento examina los problemas que enfrentan las empresas en el sector real de la economía.

Features of the Acoustic Mechanism of Core-Collapse Supernova Explosions

In the context of 2D, axisymmetric, multi-group, radiation/hydrodynamic simulations of core-collapse supernovae over the full 180$^{\circ}$ domain, we present an exploration of the progenitor dependence of the acoustic mechanism of explosion. All progenitor models we have tested with our Newtonian code explode. We investigate the roles of the Standing-Accretion-Shock-Instability (SASI), the excitation of core g-modes, the generation of core acoustic power, the ejection of matter with r-process potential, the wind-like character of the explosion, and the fundamental anisotropy of the blasts. We find that the breaking of spherical symmetry is central to the supernova phenomenon and the blasts, when top-bottom asymmetric, are self-collimating. We see indications that the initial explosion energies are larger for the more massive progenitors, and smaller for the less massive progenitors, and that the neutrino contribution to the explosion energy may be an increasing function of progenitor mass. The degree of explosion asymmetry we obtain is completely consistent with that inferred from the polarization measurements of Type Ic supernovae. Furthermore, we calculate for the first time the magnitude and sign of the net impulse on the core due to anisotropic neutrino emission and suggest that hydrodynamic and neutrino recoils in the context of our asymmetric explosions afford a natural mechanism for observed pulsar proper motions.

Electromagnetohydrodynamics

Interaction of plasma flow with a magnetic obstacle is a frequent process in many laser-plasma experiments in the laboratory, and is an important event in many astrophysical objects such as X-ray pulsars, AGN, GRB etc. As a result of plasma penetration through the magnetic wall we could expect a formation of magnetohydrodynamic (MHD) shock waves, as well as of electromagnetic (EM) ones. To study these processes we need equations following from hydrodynamic and Maxwell equations, which in the limiting situations describe MHD and EM waves, and are valid for the general case, when both phenomena are present. Here we derive a set of equations following from hydrodynamic and Maxwell equations, without neglecting a displacement current, needed for a formation of EM waves. We find a dispersion equation describing a propagation of a weak linear wave in a magnetized plasma along the $x$ axis, perpendicular to the magnetic field $H_y(x)$, which contains MHD, hydrodynamic and EM waves in the limiting cases, and some new types of behaviour in a general situation. We consider a plasma with zero viscosity and heat conductivity, but with a finite electric conductivity with a scalar coefficient.Comment: 8 papers, 8 figures, 1 table, to be submitted in PR
