Application of flood index in monitoring Flood-plain ecosystems (by the example of the Middle Ob flood-plain)

The concept of regional hydroecological monitoring has been developed for the flood-plain of the Middle Ob. Its object is to control the state of flood-plain ecosystem productivity for organization of scientific, regional-adopted and ecologically regulated nature management. For this purpose hydroecological zoning of flood-plain territory performed, the most representative stations of water-gauge observations for each flood-plain zone organized, the scheme of flood-plain flooding was prepared. On the basis of observations within more than 50_years flood hydrographs were composed, the part which forms the flood influence was calculated. It was presented through the complex factor - index of flood influence. The graphs of the flood influence index changes at reference water stations from 1935 to 2000 were presented

Multiphase turbulence mechanisms identification from consistent analysis of direct numerical simulation data

Direct Numerical Simulation (DNS) serves as an irreplaceable tool to probe the complexities of multiphase flow and identify turbulent mechanisms that elude conventional experimental measurement techniques. The insights unlocked via its careful analysis can be used to guide the formulation and development of turbulence models used in multiphase computational fluid dynamics simulations of nuclear reactor applications. Here, we perform statistical analyses of DNS bubbly flow data generated by Bolotnov (Reτ= 400) and Lu–Tryggvason (Reτ= 150), examining single-point statistics of mean and turbulent liquid properties, turbulent kinetic energy budgets, and two-point correlations in space and time. Deformability of the bubble interface is shown to have a dramatic impact on the liquid turbulent stresses and energy budgets. A reduction in temporal and spatial correlations for the streamwise turbulent stress (uu) is also observed at wall-normal distances of y+= 15, y/δ = 0.5, and y/δ = 1.0. These observations motivate the need for adaptation of length and time scales for bubble-induced turbulence models and serve as guidelines for future analyses of DNS bubbly flow data.

STREAM AS A NEW HYPERMEDIA GENRE

The relevance of the study is due to changes in media culture evoked by new technologies that stimulate the emergence of a new hypertext genre-stylistic reality. The article examines a new media phenomenon – stream.The stream is considered as public communicative flow that takes place in real time and includes text, as well as video and audio content, organized by the streamer (the author) – information and media personality with the active involvement of other media participants of different types; it is implemented in live Internet broadcasting; it creates a variety of opportunities for any participant (from commenting, polling, to participation in action). The stream emerged from the instrumental-service approach to the development and comprehension of various relevant topics in the content presentation. The aim of the participants in this media process is self-expression and self-actualization, the incentive to be active and interact (from personal motives to socially significant ones). As a hypermedia genre it is considered on the material of media discourse “#daiDudya” with the participation of A.A. Venediktov, taking into account his linguistic and extralinguistic characteristics. The study of the stream as a new and insufficiently investigated phenomenon of modern media communication, the development of a methodology for its analysis are of interest for communicative and cognitive linguistics, media linguistics, sociology, psychology, discourse, and cultural linguistics

Peculiarities of argumentation in media discourse of language personality of syncretic type (on the material of blogs by social and political journalist G. I. Mirskiy)

The article considers specific character of argumentation activity of famous public language personality in the aspect of typological and individual peculiarities on the example of media discourse of G. I. Mirskiy (a scientist, social and political journalist, political scientist, blogger) as a personality of syncretic type. The character of argumentation is presented as an important feature of definition of informational and media language personality type subject to specificity of its communicative, cognitive and speechcultural peculiarities. The blog as one of the media genres is viewed in the capacity of representative type of text which allows judging the individual specificity of discursive activity of language personality. Media discourse of G. I. Mirskiy in the blog genre with a glance to selection and organizing language means in the context of real situations and orientation on mass addressee reflects its belonging to elite type of speech culture, which shows opened social appraisal and allows to conclude its communicative roles, communicative tactics and strategies of communication typical for argumentation in textual activity of social and political journalist, and also on his mental and psychological peculiarities, author’s individual demonstrations of concept sphere, thematic preferences, scale and character of world’s knowledge and belonging of this language personality to informants of empiric substyle of cognitive style.На примере медиадискурса Г. И. Мирского — ученого, публициста, политолога, блогера как личности синкретичного типа рассмотрена специфика аргументативной деятельности известной публичной личности в аспекте типологических и индивидуально-авторских особенностей. Характер аргументации представлен как важная черта в определении типа информационно-медийной языковой личности с учетом специфики ее коммуникативных, когнитивных и культурно-речевых особенностей. Блог как один из медийных жанров рассмотрен в качестве репрезентативного типа текста, позволяющего судить об индивидуальном своеобразии дискурсивной деятельности языковой личности. Медиадискурс Г. И. Мирского в жанре блога с учетом отбора и организации языковых средств в контексте конкретных ситуаций и ориентации на массового адресата отражает его принадлежность к носителям элитарной речевой культуры, проявляющим открытую социальную оценочность, позволяет судить о его коммуникативных ролях, коммуникативных тактиках и стратегиях общения, характерных для аргументации в текстовой деятельности публициста, о некоторых его ментально-психологических особенностях, индивидуально-авторских проявлениях концептосферы, тематических предпочтениях, масштабе и характере знаний о мире, а также о принадлежности данной языковой личности к носителям эмпирического субстиля когнитивного стиля.Публикация подготовлена в рамках поддержанного РГНФ научного проекта № 15-04-00216
