The current paper presents the results of a full-scale study of the fluorescence features of pollutants ( diesel fuel, Urals oil), as well as an alcoholic solution of oleic acid, which imitates oil by visco-elastic characteristics. The experiment was carried out on the Gorky Reservoir under conditions of wind waves. Local areas of artificial slicks were created for multiple intersections at different angles to the wind and waves with continuous lidar sounding of the upper water layer. Signals were recorded by the ninth generation UVL-9 laser ultraviolet fluorescent lidar developed by the Institute of Oceanology of the Russian Academy of Sciences. At signal analysis, spectral intensities and fluorescence features of the studied substances are determined, possibilities of slick detecting as well as film thickness estimation are made, examples of surfactant film detecting behind the oleic slick where visual observation of pollutants does not give a result are showed. The obtained results are useful for the further development of fluorescent methods and devices for operational remote sensing of surface pollution on wave water surface.

Данная статья посвящена анализу первых учебных книг, заложивших основу для дальнейшего развития учебного книгоиздания по вопросам изучения французского языка в России. Проанализированы наиболее известные первые учебники по французскому языку: «Новая францусская грамматика…» В.Е. Теплова, «Французская азбука» А. де Лави, «Наставление как по-французски…» Я. Сигезбека, «Французская азбука» Академии наук, «Новый французский словарь» П.И. Богдановича и др. Автор приходит к выводу, что все учебники французского языка рассматриваемого периода выступают своеобразным «зеркалом», отражающим прогресс, имевший место в российской педагогической мысли. Важным наблюдением признается тот факт, что многие французские азбуки, целевой аудиторией которых выступали учащиеся гимназий, приобретали популярность среди изучавших французский язык самостоятельно. Иными словами, они переходили в разряд самоучителей, в значительной степени расширяя тем самым их функциональную характеристику. The article is devoted to the analysis of the first educational books that laid the foundation for the further development of educational publishing on the study of the French language in Russia. The most famous first textbooks on the French language are analyzed: «New French grammar ...» by V. Ye. Teplov, «French alphabet» by A. de Lavi, «Manual...» by J. Sigesbek, «French alphabet» by the Academy of Sciences, «New French Dictionary» by PI Bogdanovich, etc. The author comes to the conclusion that all French textbooks of the period under review act as a kind of ‘mirror’ which reflects the progress that took place in Russian pedagogical thought. An important observation is the fact that many French alphabets, aimed for students, gained popularity among those who studied French on their own. In other words, they passed into the category of self-instruction manuals, thereby significantly expanding their functional characteristics.

Relevance . The article provides an analysis of the infectious mor-bidity in the Russian Federation of humans, domestic animals and birds for 2016-2019. The aim of the study is to compare the epizootological and epidemiological situation and to establish a correlation between individual types of zoonoses, anthro-ponoses and zoonoses with anthroponoses. Materials and Methods . The study was carried out by processing statistical data obtained from open sources of Rosstat and the Federal State University of the Russian Academy of Sciences of the IAC of the Department of Veterinary Supervision of Vladimir. Collected data were processed using Excel and STATISTICA-10 programs. Results and Discussion . A sample of infectious diseases (IB) was formed, which, during the specified period, infected peo-ple, pets, incl. cattle and small ruminants, pigs, horses and poultry. The average per-centage of patients with a specific type of infectious diseases was calculated, taking into account the differentiation by zoonoses, anthroponoses and the average percent-age of sick animals for all identified types of IB, which made it possible to establish IB, which are most common in each of the groups, and in general in all animals and birds. The assessment of the distribution of information security in differentiated groups has been carried out, distribution graphs have been constructed and formulas have been established by which it is possible to predict the dynamics of their further development. The STATISTICA-10 software was used to calculate the correlation coefficients ( r ) between zoonoses (XX), anthroponoses (YY), as well as zoonoses and anthroponoses (XY). Conclusion . Stably significant positive correlations were determined for zoonoses and anthroponoses. The data obtained prove the existence of a close connection of a person with the environment and his responsibility for the health of animals and birds, in order to prevent the risk of infectious diseases.

Turbulent Statistics

New experiments have been carried out in a large laboratory channel to explore the structure of turbulent motion in the water layer beneath surface gravity waves. These experiments involve pure wind waves as well as wind-ruffled mechanically generated waves. A submersible two-component LDV system has been used to obtain the three components of the instantaneous velocity field along the vertical direction at a single fetch of 26 m. The displacement of the free surface has been determined simultaneously at the same downstream location by means of wave gauges. For both types of waves, suitable separation techniques have been used to split the total fluctuating motion into an orbital contribution (i.e. a motion induced by the displacement of the surface) and a turbulent contribution. Based on these experimental results, the present paper focuses on the structure of the water turbulence. The most prominent feature revealed by the two sets of experiments is the enhancement of both the turbulent kinetic energy and its dissipation rate with respect to values found near solid walls. Spectral analysis provides clear indications that wave–turbulence interactions greatly affect energy transfers over a significant frequency range by imposing a constant timescale related to the wave-induced strain. For mechanical waves we discuss several turbulent statistics and their modulation with respect to the wave phase, showing that the turbulence we observed was deeply affected at both large and small scales by the wave motion. An analysis of the phase variability of the bursting suggests that there is a direct interaction between the waves and the underlying turbulence, mainly at the wave crests. Turbulence budgets show that production essentially takes place in the wavy region of the flow, i.e. above the wave troughs. These results are finally used to address the nature of the basic mechanisms governing wave–turbulence interactions.

AbstractElectromagnetic interference (EMI) shielding for visual observation applications, such as windows utilized in military or aerospace, is important but difficult to realize due to conventional materials having difficulty in achieving sufficient transparency and EMI shielding simultaneously. In this paper, we present multilayered structures based on salt water for simultaneous highly optical transparency (OT) and EM shielding effectiveness (SE) performance. In the proposed structures, planar acrylic and glass were used as two types of clear substrates to hold salt water. The measured OT of both acrylic/salt water/acrylic and glass/salt water/glass structures was higher than 90% with a nearly uniform light transmission, which introduced a negligible impact on optical observation. Furthermore, both simulations and experimental results demonstrated that the SE of the multilayer structure was higher than 20 dB in the X-band from 7.5 to 8.5 GHz. Moreover, the SE was significantly enhanced by increasing the thickness of the salt water layer. Especially, both OT and SE of the multilayered structures were improved simultaneously by increasing the salinity of the salt water. These proposed structures demonstrate great potential in EMI shielding observation applications.

The helium-cooled Gas Fast Reactor (GFR) is one of the six reactor concepts selected for further development in the frame of the Generation IV International Forum (GIF). Since no gas cooled fast reactor has ever been built, a small demonstration reactor is necessary on the road towards the full-scale GFR reactor. A concept of this demonstrator is called ALLEGRO. The French Commissariat à l’énergie atomique et aux énergies alternatives (CEA) developed between 2001–2009 a pre-conceptual design of both the full-scale GFR called GFR2400 and the small demonstration unit called ALLEGRO (75 MWt). Since 2013 ALLEGRO has been under development by several partners from Czech Republic, France, Hungary, Poland and Slovakia. No severe accident study of ALLEGRO using a dedicated computer code has been published so far. This paper is the first attempt to perform computer simulations of the ALLEGRO CEA 2009 concept, using MELCOR version 2.1. A model of the ALLEGRO CEA 2009 concept has been developed with the aim to perform safety analyses; to confirm that MELCOR can be used for such a study, to investigate what scenarios lead to a severe accident and to study in detail the progression of the severe accident during the in-vessel phase. Several pressurized and depressurized protected scenarios were investigated; four of them are presented in this paper. It was observed that even long-lasting station blackout (SBO) without further failures of the passive safety systems does not lead to a severe accident as long as there is enough water in the decay heat removal (DHR) system. Loss of coolant (LOCA) transients with DHR system in the forced-convection mode can lead to peak cladding temperatures causing limited core damage in the early phase of the accidents, but without further development into core meltdown. On the other hand, LOCA combined with SBO leads to excessive core melting in orders of minutes, which represents a weak point of ALLEGRO 2009 concept. Recommendations were formulated for the further development of the ALLEGRO concept.

The paper presents a comparative analysis of some selected Latvian and Russian paremias, the bulk of which has been collected in the time period since the 1970s till nowadays in the south-eastern part of Latvia – Latgale, and studied in the context of Latvian proverbs included in folklore collections and phraseological dictionaries, as well as the archival materials of the Latvian Academy of Sciences and works by Latvian folklorists. The aim of the study is to analyse prototypical paremias from the Holy Scripture and trace the history of their existence and further development among the Latvians and the Russians in the Latgale region based on the qualitative data analysis. The conducted research allows concluding that similar worldview patterns of the Latvians and the Russians are to be searched for in Christianity. The analysed proverbs testify to the fact that culture is a unifying factor for different ethnic groups living in the same region.

Achievements in development of the technique of operational measurements of the water structure in the bottom layer, based on vertical profiling of the water column using standard multiparameter probes operated with an armored cable in a free fall mode from surface to bottom are presented. Instead of cable winches, simpler devices operating on the principle of longline houler have been proposed. Full-scale tests have shown that the new universal Underway CTD system is not inferior to its counterparts and has prospects for further development.

Large Municipality

The restructuration of municipalities which has been decided by the Belgian government, is not only a purely technical operatzon but rather, and in the first place, a social problem. The shape and duty-profile of a local authority should not, indeed, be attuned only to fast changing expectations as far as services are concerned, but to consultation and participation as well.Public administration research cannot keep aloof from this debate, but is considerably hampered by the institutional confusion and the insufficient explicitation of the aims of the present reform. A starting-pointcan, however, be found in the mergers of municipalities that were realized in 1964 and in 1970/1971. In 67 of these municipalities an inquiry was held concerning the consequences of the merger, and moreover, in twotest-cases (Oudenaarde and Brugge) this inquiry grew to a full-scale systematic policy analysis.This research shows that, as a rule, the former municipalities are reasonably represented in the new entity's council, but it also reveals that few efforts are made to give this representation a broader impact along formal or informal participation-channels. Integration of employees has not caused insurmountable problems. However, in large sized municipalities, resulting from mergers, one could notice a drastic increase in municipal personnel, not only with regard to new duties and objectives but to traditional administrative and police duties as well. Such a phenomenon points to the far-reaching changes which a substantial scale-increase provokes in a municipality's structure and policy profile. A large municipality resulting from mergers is no langer a simple sum of component parts, but a completely new entity, wishing to catch up as fast as possible with comparable municipalities that passed through a progressive growth process. Therefore, scale-increase is not only a means of economizing or an intra-administrative matter, but rather a way of creating chances for further development or wealth and well-being.

The article provides an assessment of perspectives of quinoa (Chenopodium quinoa L.) cultivation in Ukraine, based on international experience and original fi eld tests, with the aim of ensuring further development and diversifi cation of crop production in Ukraine and expanding modern crop rotation systems. The data on the taxonomic position of quinoa and its relationships with other species of the genus Chenopodium and the history of species domestication are provided. Quinoa is a crop of high nutritional value and can be used in gluten-free diets, which are important components of human ration. The results of test cultivation of quinoa in 2013–2014 under conditions of the experimental agricultural farm of the Institute of Plant Physiology and Genetics, Na- tional Academy of Sciences of Ukraine, located in Vasylkiv District (rayon) of Kyiv Region (oblast), are pro- vided. It is concluded that quinoa is a promising crop for domestic grain producers. The introduction of quinoa into crop rotation systems can improve ecological conditions of agroecosystems and promote restoration of soil fertility in the country without diminishing the revenues of farmers.

Term Analysis

This paper presents a method for predicting extreme roll motion on an FPSO using long-term statistics. The method consists of a long-term simulation where a database of consecutive short-term sea states with combined weather conditions, including direction and magnitude of wind, wind waves and swell waves, is used. The vessel heading in given weather conditions is simulated. For each combined sea state, the short-term roll motion maxima are calculated to form a long-term probability distribution, and the extreme roll motion, e.g. the 100-year value, can be estimated from the distribution. For an example FPSO, the results from the long-term analysis have been compared with full-scale measurements, giving a validation of the method. This paper is a shortened version of [1].
