Communicative discourse of terminology used in gastronomical media culture

This article aims to analyze and describe the food discourse and terms of the French language, as well as to determine correlations with the French national and cultural worldview. The study also considers the current state of "gastronomical discourse" based on the French food semiotic and communicative mode

Current state of forest mapping with Landsat data in Siberia

We review a current state of a forest type mapping with Landsat data in Siberia. Target algorithm should be based on dynamic vegetation approach to be applicable to the analysis of the forest type distribution for Siberia, aiming at capability of mapping Siberian forest landscapes for applications such as predicting response of forest composition to climate change. We present data for several areas in West Siberian middle taiga, Central Siberia and East Siberia near Yakutsk. Analysis of the field survey, forest inventory data was made to produce forest type classification accounting for several stages for forest succession and variations in habitats and landforms. Supervised classification was applied to the areas were the ground truth and inventory data are available, including several limited area maps and vegetation survey transects. In Laryegan basin in West Siberia the upland forest areas are dominated by mix of Scots pine on sandy soils and Siberian pine with presence of fir and spruce on the others. Abundance of Scots pine decreases to the west due to change in soils. Those types are separable using Landsat spectral data. In the permafrost area around Yakutsk the most widespread succession type is birch to larch. Three stages of the birch to larch succession are detectable from Landsat image. When Landsat data is used in both West and East Siberia, distinction between deciduous broad-leaved species (birch, aspen, and willow) is generally difficult. Similar problem exist for distinguishing between dark coniferous species (Siberian pine, fir and spruce). Image classification can be improved by applying landform type analysis, such as separation into floodplain, terrace, sloping hills. Additional layers of information can be a promising way to complement Landsat data

Properties of filled compositions based on emulsion pvc

Set influence of chalk on the technological and technical properties of plastisol and compounds of PVC emulsion used in the manufacture of children's toys. Studied rheology filled with chalk plastisol and compounds. We studied the stability filled with chalk plastisols. Given the elastic-strength properties filled with plasticized PVC

Toponymic phraseological unit, linguistic thinking and discourse: Russia, France and Italy

Studies phraseological units with a toponymic component on the material of linguistic and discursive manifestations in Russian, French and Italian linguistic cultures. National discourse in correlation with linguistic thinking is studied based on interpretative analysis of phraseology. In the context of the anthropocentric paradigm, the authors carry out a linguistic interpretation of systemic toponymic phraseological mean

Politician's linguistic personality as key figure of institutional discourse

The article deals with the approaches to studying a politician's linguistic personality. The communicative potential of the manifestation means of a politician's personality is analyzed. The authors present the algorithm of studying the characteristics of an institutional linguistic personalit

Features of French, American and Russian intercultural interaction

The article deals with the functioning of cultural stereotypes in French, American and Russian linguistic consciousness. Cross-cultural interaction is interpreted within the framework of mastering linguocultural communication codes and the worldview of allophones. The analysis of factual data is based on the linguosemiotic approach to its interpretation within a discursive utterance

Topological classification of black Hole: Generic Maxwell set and crease set of horizon

The crease set of an event horizon or a Cauchy horizon is an important object which determines qualitative properties of the horizon. In particular, it determines the possible topologies of the spatial sections of the horizon. By Fermat's principle in geometric optics, we relate the crease set and the Maxwell set of a smooth function in the context of singularity theory. We thereby give a classification of generic topological structure of the Maxwell sets and the generic topologies of the spatial section of the horizon.Comment: 22 pages, 6 figure

Actual Issues of Ischemic and Hemorrhagic Events Risk Management During Antithrombotic Therapy in Patients with Acute Coronary Syndrome

Today, optimal duration of double antiplatelet (DAPT) and triple antithrombotic therapy (TATT) in patients with acute coronary syndrome (ACS) remains the subject of scientific and practical discussion on possibilities of ischemic and hemorrhagic risks assessment. Good clinical risk metrics is based on validated risk scales. However, actual clinical guidelines do not provide a universal and generally accepted scale for assessing the balance of risks of ischemic events and bleeding. Is very necessary to determine the optimal content and DAPT or TATT duration is the existence of validated risk assessment scales would allow to optimize the accuracy of risk assessment of ischemic and hemorrhagic events in patients after ACS. One of the probable reasons is absence of validation of existing scales for each specific population of patients with ACS. In this regard, the use of «new» risk assessment systems: PRECISE DAPT and DAPT, in addition to the routine risk assessment scales (GRACE, CRUSADE), could become optimal in all ACS patient categories. In order to identify the initial risk of community-acquired hemorrhagic events during the first 12 months all patients with ACS at the inpatient stage of treatment is used the PRECISE DAPT score. In order to determine the need for prolongation of the standard DAPT. It should be used after 12 months of receiving DAPT in survivors of ACS patients without ischemic events, must be used the DAPT score

Azimuthal dependence of pion source radii in Pb+Au collisions at 158 A GeV

We present results of a two-pion correlation analysis performed with the Au+Pb collision data collected by the upgraded CERES experiment in the fall of 2000. The analysis was done in bins of the reaction centrality and the pion azimuthal emission angle with respect to the reaction plane. The pion source, deduced from the data, is slightly elongated in the direction perpendicular to the reaction plane, similarly as was observed at the AGS and at RHIC.Comment: 5 pages, 2 figure
