Modern Museum Communications as a Means of Visitors Attracting
The purpose of the study is to analyze the websites of museums in Russia in the European context. The Fine Arts museums in five regional centers of Russia and European Union, namely, in France, Germany, Poland, Croatia, and Lithuania were chosen for the assessment of their websites by four criteria: design, content, usability, and dynamism. A rating of the target Russian museum websites was compiled based on a comparative analysis of their compliance with these criteria. The findings allow concluding that some of the web resources of Russian regional museums meet the European standards, which let them powerfully join the modern virtual space and win both Russian and foreign audiences. The scienŃe-based approach to a single virtual cultural space, which is currently on the focus of the museum institutions, supports the assumption of the museum websites to be a potent tool for the art communication with society. The practical value of the study is determined by possible uses of the results in streamlining and upgrading the museum sites, as well as in courses and training programs on museology, management, and marketing of social and cultural activities
Reduction of power consumption during arc welding operation
The work is devoted to energy saving during arc manual welding operations. Power sources for arc manual welding are rectifiers with slow or steeply falling current-voltage characteristics. The paper considers two ways of energy saving during arc welding operations. The first way is to increase the efficiency of welding by replacing the ballast rheostat with a special electronic device that regulates the welding current instead of the ballast rheostat. The second way is to increase the efficiency of the welding equipment by replacing a traditional one-bridge rectifier with the two-bridge economical rectifier. An approximate calculation of the annual economic effect from the replacement of a ballast rheostat by the electronic regulating device is given on the example of welding operations in a typical assembly shop

Bounds for the Tail Distributions of Suprema of Sub-Gaussian Type Random Fields
The paper presents bounds for the distributions of suprema for particular classes of Ï-sub-Gaussian random fields. Results stated depend on representations of bounds for increments of the fields in different metrics. Several examples of applications are provided to illustrate the results, in particular, to random fields related to stochastic partial differential equations and partial differential equations with random initial conditions

It has been experimentally proven that it is possible to produce nanoporous materials of the nuclear filter group from the film polycyanurates. As the prospect of progress in the technology of nanoporous films from polycyanurates, the possibility of involvement of radiation polymerization mechanisms to obtain filter materials with desired physicochemical properties and structure is considered.

Le plurilinguisme Ă lâĂ©preuve de la traduction
Le prĂ©sent recueil dâarticles explore certaines marges de la traduction, des domaines pĂ©riphĂ©riques oĂč tant le traduire que le traduit posent problĂšme. Câest le cas textes oĂč la langue Ă©trangĂšre se prĂ©sente comme un objet, une image reprĂ©sentative de lâAutre. La situation linguistique particuliĂšre de certains pays et aires culturelles peut rendre possible lâĂ©criture de textes mettant deux ou plusieurs langues en contact. Il importe de rendre ce plurilinguisme, câestâĂ âdire ne pas traduire ce qui se prĂ©sente comme un corps Ă©tranger dans le texte dâorigine. Mais comment faire lorsque le lecteur de lâĆuvre de la langue cible ne possĂšde pas potentiellement les mĂȘmes compĂ©tences linguistiques que le lecteur de la langue source ? Les mots Ă©trangers peuvent ĂȘtre transcrits fidĂšlement, phonĂ©tiquement ou encore ĂȘtre mĂ©langĂ©s Ă la langue du locuteur, ce qui dĂ©note des attitudes diffĂ©rentes envers lâAutre, sa communautĂ© linguistique ou, plus largement, envers lâunivers Ă©tranger, et peut se prĂ©senter comme un jugement. Les articles qui suivent examinent les questions de la restitution de la langue mĂȘlĂ©e Ă des ancrages culturels spĂ©cifiques dans la traduction. Ils sâinterrogent Ă©galement sur la possibilitĂ© de restituer lâeffet de la lecture produit dans une culture cible, la possibilitĂ© dâimiter une situation de diglossie ou encore reprĂ©senter lâĂ©trangetĂ© avec ses spĂ©cificitĂ©s dâorigine
Thermally stable nanoporous cyanate ester resin/linear polyurethane hybrid networks created by nuclear technologies
International audienceThermally stable nanoporous polymer films have been created as promising materials for membrane technologies. Thermosetting Cyanate Ester Resins (CERs) and linear polyurethane (LPU) were combined by stepwise thermal curing, and the films of resulting hybrid polymers were irradiated with α-particles followed by chemical etching. Well-defined highly regular nanoporous structures were developed in the films as evidenced by using SEM. No significant changes in chemical structure of the polymer systems obtained after α-irradiation were observed by FTIR spectroscopy measurements. The polymer films obtained on the basis of hybrid networks with the CER/LPU composition equal to 90/10 wt.% had quite narrow pore diameter distribution with average pore diameters around 12 nm. DSC and TGA measurements showed that the thermal characteristics of the nanoporous films were sufficiently high (Đąg ~ 167 °C to ~199 °C, Đąd5% ~ 293-359 o C, and Đąd max ~ 429-457 o C). The CER/LPU nanoporous thermosetting materials demonstrated effective gas transport properties tested with gases, such as Đ2, ĐĄĐ2, N2, and ĐĄĐ4. The combination of an additional sensitization step using -rays and longer time of chemical etching improved the properties of the nanoporous systems developed. Such materials open the way to numerous applications, for example, as ultrafiltration membranes for advanced technologies, especially under extreme conditions
Propos sur l'intraduisible
Alors que lâactivitĂ© de traduction est universelle, se pose la question de la part du traduisible et de lâintraduisible et, surtout, celle de la nature de ce dernier. La traductologie (Jakobson, Mounin, Meschonnic, Berman) a thĂ©orisĂ© de diverses maniĂšres la traduction, ses processus et ses acteurs, de lâauteur en langue source jusquâau lecteur en langue dâaccueil, le possible, le nĂ©cessaire et lâimpossible Ă traduire. Dans la pratique, tout traducteur littĂ©raire est confrontĂ© Ă des Ă©lĂ©ments quâil juge « intraduisibles », mais les textes traduits proposĂ©s Ă la lecture se prĂ©sentent implicitement comme les Ă©quivalents exacts des originaux et comportent rarement la trace des hĂ©sitations et interrogations des traducteurs, le plus souvent sous la forme de notes explicatives en bas de page. Lâintraduisible peut ĂȘtre dâordre rĂ©fĂ©rentiel : lâinexistence dans la langue dâune culture donnĂ©e dâune entitĂ© quelconque, matĂ©rielle ou notionnelle, peut aller de pair avec une existence de moyen lexical. Ce fait a Ă©tĂ© dĂ©crit Ă propos des traductions de la Bible, dans la confrontation du vocabulaire liĂ©e Ă la neige chez les Inuits, etc. Lâintraduisible est ici tout relatif et relĂšve encore du domaine de lâexplicable. Lâintraduisible peut ĂȘtre plus proprement linguistique : les jeux de mots, mais aussi certains traits grammaticaux, faits de morphologie ou tournures syntaxiques peuvent gĂȘner, voire empĂȘcher la traduction, ou au contraire, contraindre le traducteur Ă prendre des dĂ©cisions que lâauteur nâa pas eu Ă prendre. Est-il possible et nĂ©cessaire dâexpliquer une assonance, lâemploi dâune structure syntaxique ? Il sâagit dâĂ©tudier lâintraduisible dans la pratique du traducteur, la nature de lâintraduisible, les « techniques » dâĂ©vitement ou dâaffrontement mises en Ćuvre pour produire un texte cohĂ©rent et lisible. Les langues mises en prĂ©sence seront le français, lâallemand et les langues slaves
