L'autoapprendimento multimediale del russo per principianti: Kraski
Liudmila Buglakova,Simona Berardi
Studi Slavistici , 2004,
Abstract: Multimedia self-study of the Russian language at beginners' level: Kraski Kraski was developed at the Interfaculty Language Centre of Forlì (University of Bologna) and is intended for use for self-study of the Russian language in an academic context. The Interfaculty Language Centre in Forlì decided not to use a ready-made software for the realization of this project but, instead, designed software which takes into account not only the language-learning aims but also the needs of the user. Kraski is divided into four topic units which become increasingly more difficult as regards linguistic ability and communicative competence. Each unit presents three situations through the use of a video clip, each of these is followed by six exercises designed to consolidate vocabulary and morphological knowledge. In most of the exercises, the user is helped by the use of the grammar cards: as the course is designed to improve communicative competence, the grammar explanations are given solely as an aid to the learner within the context of the course and are presented schematically. If an exercise includes unknown vocabulary then a hypertext link allows the user to consult a multimedia vocabulary card which includes images and sounds. At the end of every topic unit, we find the section Talking about . which contains different speaking activities which act as a sort of self-evaluation of the progress made and help to improve communicative ability. The self-study user is also helped by the presence of several aids which can be consulted at any time: Cyrillic Alphabet, The Sounds, Grammar Cards, Vocabulary Cards, Dictionary.

Vladimir Mukhomorov, Liudmila Anikina
Open Journal of Soil Science (OJSS) , 2011, DOI: 10.4236/ojss.2011.11001
Abstract: It is presented the results of a long-term and intensive experiment, which models the processes of primary soil formation under controlled agro-ecosystems. The influence of mineral substrate transformation is analyzed on the content of chemical elements in plants tomato, and wheat. For the first time have been established dynamic synergistic and antagonistic interrelations between the chemical elements in a various bodies of the plant (roots, reproductive bodies, stems, and leaves). Using methods of the theory of information was revealed dynamics of collective state of chemical elements in the plants. It is shown that the collective states of the chemical elements which defined by the information function is strictly differentiated for different plant bodies, and have hierarchic order. We analyzed the following chemical elements Si, Al, Fe, Mg, Ca, K, P, S, Cl, Na, Mn, Zn.
An Analogy between the Properties of “Dark Energy” and Physical Vacuum Consisting of Quantum Harmonic Oscillators Characterized by Zero-Point Energy  [PDF]
Liudmila B. Boldyreva
Journal of Modern Physics (JMP) , 2019, DOI: 10.4236/jmp.2019.101003
Abstract: In quantum field theory, the physical vacuum, free from magnetic and electric fields (without regard to gravitational energy), is defined not as an empty space but as the ground state of the field consisting of quantum harmonic oscillators (QHOs) characterized by zero-point energy. The aim of this work is to show that such physical vacuum may possess the properties similar to the properties of dark energy: the positive density, the negative pressure, and the possibility of so-called accelerated expansion. In the model discussed, the mass of QHOs determines the positive density of dark energy. The observed electric polarization of physical vacuum in an electric field means the existence of electric dipole moment of QHO, which, in turn, suggests the existence inside the QHO of a repulsive force between unlike charges compensating the attractive Coulomb force between the charges. The existence of such repulsive force may be treated as the existence of omniradial tensions inside every QHO. In terms of hydrodynamics, it means that the vacuum with this property may be regarded as a medium with negative pressure. The electric dipole-dipole interaction of QHOs under some condition may result in the expansion of physical vacuum consisting of QHOs. It is shown also that the physical vacuum consisting of QHOs is a luminiferous medium, and based on this concept the conditions are discussed for the emergence of invisiblity of any objects (in particular, dark matter). The existence of luminiferous medium does not contradict the second postulate of special relativity (the principle of constancy of the velocity of light in inertial systems), if to take into account the interaction of photons with QHOs and with virtual photons (the virtual particles pairs) created by quantum entities that constitute the inertial systems.
Regional models of metal production in Western Asia in the Chalcolithic, Early and Middle Bronze Ages
Avilova, Liudmila
Trabajos de Prehistoria , 2008,
Abstract: The objective of this work is the reconstruction and comparative analysis of regional models of metal production in the Chalcolithic, Early and Middle Bronze Ages. The work is based on the statistical analysis of unique computer database on archaeological metal finds from four regions of the Near East: Anatolia, Mesopotamia, the Levant, and Iran. The materials are analysed by four indicators: distribution by the chronological periods, artefacts’ function, proportion of used metals and copper- based alloys. The author presents a series of conclusions concerning the preconditions for the beginnings of metal production in Western Asia and the pioneering role of Iran in its emergence, the important role the piedmont territories played in the development of metal production, the leap-like pattern of production dynamics shown by the periods, and its relation to the spread of a producing economy, long-distance exchange, and the emergence of the early civilizations. El objetivo de este trabajo es la reconstrucción y análisis comparativo de modelos regionales de producción metalúrgica del Calcolítico y la Edad del Bronce Inicial y Media. Se basa en el análisis estadístico de una base de datos única sobre hallazgos metálicos de cuatro regiones del Próximo Oriente: Anatolia, Mesopotamia, el Levante e Irán. Los materiales se analizan atendiendo a cuatro variables: períodos cronológicos, función de los artefactos, proporción de los metales usados y las distintas aleaciones del cobre. La autora aporta una serie de conclusiones respecto a las precondiciones para los inicios de la producción metalúrgica en el Oeste Asiático; sobre el papel pionero de Irán en su aparición; la importancia de los piedemontes en su desarrollo; el patrón no continuo que se observa en las dinámicas de producción por periodos; y su relación con la expansión de la economía de producción, el intercambio a larga distancia y la aparición de las primeras civilizaciones.
Assessing and Increasing the Competitiveness of Republic of Moldova Wine Sector
Liudmila ANTOHI
Annals of Dun?rea de Jos University. Fascicle I : Economics and Applied Informatics , 2011,
Abstract: Competitiveness is the capacity of countries to create an enabling environment for indigenous business development; using low-cost strategies, differentiation, substitution, leading to increased productivity; creating opportunities to penetrate foreign markets and added value through their form; citizens by providing jobs with high pay, increasing the purchasing power; contributing to economic growth and to establish a balanced social environment. Enhancing competitiveness of national economy is one of five strategic priorities of the Republic of Moldova, stated in the draft National Development Plan. The wine industry is one of the most important branches of national economy in Moldova. But for Moldova's wine production to be competitive on the world market, wine industry itself should become a branch of modern, efficient, with high economic efficiency, which will not be achieved without investment and without attracting high quality production.

Liudmila Mikalayeva
European Integration Online Papers , 2009,
Abstract: This paper conducts a multi-value Qualitative Comparative Analysis (QCA) of the formal adoption and sustainability of minority protection rules in four new EU member states (Poland, Romania, Estonia, Latvia) over a twelve-year period including pre- and post-accession phases (1997-2008) and five minority protection related issue areas (non-discrimination, language use, education, citizenship, integration of Roma) based on four conditions (external incentives, government position, veto players, size of minorities), in order to investigate under which external and domestic conditions minority protection and non-discrimination measures are adopted, maintained or revoked in new member states before and after accession to the EU.
Toward a New Gold Standard for Early Safety: Automated Temperature-Controlled hERG Test on the PatchLiner?
Liudmila Polonchuk
Frontiers in Pharmacology , 2012, DOI: 10.3389/fphar.2012.00003
Abstract: The Patchliner? temperature-controlled automated patch clamp system was evaluated for testing drug effects on potassium currents through human ether-à-go-go related gene (hERG) channels expressed in Chinese hamster ovary cells at 35–37°C. IC50 values for a set of reference drugs were compared with those obtained using the conventional voltage clamp technique. The results showed good correlation between the data obtained using automated and conventional electrophysiology. Based on these results, the Patchliner? represents an innovative automated electrophysiology platform for conducting the hERG assay that substantially increases throughput and has the advantage of operating at physiological temperature. It allows fast, accurate, and direct assessment of channel function to identify potential proarrhythmic side effects and sets a new standard in ion channel research for drug safety testing.
Dynamics in Nonlocal Cosmological Models Derived from String Field Theory
Liudmila Joukovskaya
Physics , 2007, DOI: 10.1103/PhysRevD.76.105007
Abstract: A general class of nonlocal cosmological models is considered. A new method for solving nonlocal Friedmann equations is proposed, and solutions of the Friedmann equations with nonlocal operator are presented. The cosmological properties of these solutions are discussed. Especially indicated is $p$-adic cosmological model in which we have obtained nonsingular bouncing solution and string field theory tachyon model in which we have obtained full solution of nonlocal Friedmann equations with $w=-1$ at large times. The possibility of obtaining realistic value of cosmological constant from nonlocal cosmological models is also discussed.
Construction Of Difference Schemes For Nonlinear Singular Perturbed Equations By Approximation Of Coefficients
Liudmila Rozanova
Mathematics , 2010,
Abstract: Mathematical modeling of many physical processes such as diffusion, viscosity of fluids and combustion involves differential equations with small coefficients of higher derivatives. These may be small diffusion coefficients for modeling the spreading of impurities, small coefficients of viscosity in fluid flow simulation etc. The difficulty with solving such problem is that if you set the small parameter at higher derivatives to zero, the solution of the degenerate problem doesn't correctly approximate the original problem, even if the small parameter approaches zero; the solution of the original problem exhibits the emergency of a boundary layer. As a result, the application of classical difference schemes for solving such equations produces great inaccuracies. Therefore, numerical solution of differential equations with small coefficients at higher derivatives demands special difference schemes exhibiting uniform convergence with respect to the small parameters involved. In this article author investigates two nonlinear boundary value problems on a finite interval, resulting in exponential and power-law boundary layers.
