Analysis of migration processes based on census data

The subject matter of research is the internal migration processes of the Russian population in the period from the 1960s to 2010. The research is based on the data about the territorial population flows published in the all-Union census materials of 1970, 1979, and 1989, and in the all-Russia census materials of 2002 and 2010. The basic migration flows and directions are considered. Methodologically, the analysis of migration is based on the use of end-to-end indicators enabling to assess the dynamics of migration processes over a long period. Special attention is paid to rural-urban internal migrations, the volumes, patterns and consequences of which have not been so far properly investigated or assessed. The authors offer and calculate relative indicators that have never been used to assess the processes in question. To make the census materials of the soviet and post-soviet periods comparable, the economic zoning adopted before 2000 is used, and the administrative-territorial network is unified. The authors confirm the hypothesis that from decade to decade the intensity of territorial mobility of both urban and rural population was reduced. Interregional migration flows are considered, and various tendencies and migration intensity for over four decades are de ned. The authors analyze the dynamics in the structure of migrants by the time they lived in the place of their permanent residence in various regions. The research shows that the tendencies developed at that time and persisting continue to adversely affect the territorial re-distribution of population and the regional social and economic development of the country. The research results can be used in adjusting the regional socio-economic and migration policy.The article has been prepared with the support of the Russian Humanitarian Science Foundation Project № 14–02–00525

Genres of Audiovisual Media Evolving in the Context of Media Technologies Development

The rapid development of audiovisual media at the end of the XX century has been influenced by two interacting reasons. The abolition of censorship allowed journalists to work more freely, the expansion of the radio and TV technical potential made it possible to find new forms of presentation and to use the specific expressive radio means on a broader and more creative scale.В последние годы ХХ века на развитие аудиовизуальных СМИ влияли две взаимодействующих причины: отмена цензуры позволила журналистам смело работать в прямом эфире, расширение технических возможностей радио и ТВ помогло найти новые формы подачи материала, более широко и изобретательно использовать специфические выразительные средства радио

Impact of inter-ventricular lead distance on cardiac resynchronization therapy outcomes

Cardiac resynchronization therapy (CRT) has been shown as an essential treatment of patients with heart failure, leading to improvements in symptoms, left ventricular (LV) function, and survival. However, up to 30% of appropriately selected patients remain non-responders to CRT. The aim of our study was to test a hypothesis on the impact of lead positioning in the ventricular walls on CRT response in patients with advanced chronic heart failure with and without pre-operative inter and intra-ventricular myocardial dyssynchrony. We examined 53 guideline-selected CRT candidates. Response to CRT was defined in 6 months after implantation of CRT devices. All patients underwent standard and Doppler echocardiography for assessment of LV function and mechanical dyssynchrony. Individual right ventricular (RV) and LV lead tip position, inter-lead distance, and the horizontal and vertical components were measured on the radiograph images with using an automated custom made software Our results showed that the RLV inter-lead distance is an essential parameter correlated with the CRT outcomes. A logistic model comprising the RLV inter-lead distance with parameters of dyssynchrony demonstrated a high predictive power for odds of CRT success. © 2017 IEEE Computer Society.

One of the main criteria for health is still a rate of a, which in civilization’s countries is constantly decreasing, which causes the lengthening of life.However, along with this significantly changes the structure of morbidity: reduction of infectious diseases accompanied by increased infectious. All of these diseases can be divided into professional and vocational-conditioned.   Key words: health, disease, occupational diseases, professional diseases due to

Prospects of employing modern European cultivars of spring bread wheat in the breeding for powdery mildew resistance in the Northwestern region of Russia

Background. Powdery mildew of bread wheat caused by the fungus Blumeria graminis (DC.) E.O. Speer f. sp. tritici Em. Marchal is a widespread foliar disease of wheat in regions with cool and wet climate. It infects the foliage, stem and spike of the wheat host and causes yield reduction. Breeding for resistance is the economical way to control this disease. The object of this work was to analyze spring cultivars of wheat (Triticum aestivum L.) for powdery mildew resistance and some productivity indicators.Materials and methods. The study involved 150 European spring bread wheat cultivars whose resistance to the fungus was assessed at the seedling, heading and flowering phases of plant development. The population of the fungus manifested virulence to Pm1, Pm2, Pm3a-d, Pm4a-b, Pm5a, Pm6, Pm7, Pm8, Pm9, Pm16 and Pm19, and avirulence to Pm12. The damage to seedlings was evaluated using the scale from 0 (no damage) to 4 (abundant pustules). Resistance of the adult plants was analyzed according to the scale from 9 (no damage) to 1 (abundant pustules).Results and conclusions. Of the 150 cultivars, resistance at the seedling stage was shown by 12,7%, and at the adult stage by 20,1%. The cultivars ‘Dacke’, ‘SW Estrad’, ‘Sparrow’ and ‘Aranka’ were resistant in all phases of plant growth. ‘Naxos’ was characterized by a short period from seedlings to heading. The cultivars ‘Aranka’, ‘Zuzana’, ‘Septima’, ‘Tercia’ and ‘Sparrow’ had short stems, while ‘Torka’, ‘Sparrow’ and ‘Pasteur’ – large grains

Powdery mildew resistance of Nordic spring bread wheat accessions from the collection of the Vavilov Institute (VIR)

Background. Powdery mildew is one of the harmful and destructive foliar diseases of cereal crops, caused by the fungus Вlumeria graminis (DC.) E.O. Speer f. sp. tritici Em. Marchal. Annual harvest losses may reach 10–15%, and up to 30% in an epidemic year. The VIR collection contains rich diversity of wheat, a valuable source of original material for wheat resistance breeding programs.The aim of this study was to generalize the results of long-term field and laboratory investigations on powdery mildew resistance in spring bread wheat of Nordic origin from the VIR collection and search for accessions resistant in all development phases.Materials and methods. Powdery mildew resistance was analyzed in 279 accessions originated from Sweden, Finland, Norway and Denmark. The tests were performed from 1961 to 2019 against a natural population of the fungus in VIR’s experimental field (Pushkin, St. Petersburg). Field and laboratory studies were carried out in accordance with the guidelines developed by VIR.Results. The analysis of the field data on powdery mildew resistance in spring bread wheat accessions against the Pushkin population of the fungus showed that many Nordic accessions were resistant from 1970 till 1990. These data were retested in 2012–2013. One hundred and five accessions of old landraces and modern cultivars of Nordic origin were studied under field and laboratory conditions for their response to a natural population of the fungus. Accessions resistant in all phases of plant development were identified.Conclusion. Swedish cultivars ‘Sunnan’ (k-58177), ‘Canon’ (k-60992), ‘Sober’ (k-61080) ‘Dragon’ (k-61515) and ‘Dacke’ (k-63479) preserved their resistance to the powdery mildew population beginning from 1993. Spring bread wheat cultivars ‘SW Vals’ (k-64436), ‘SW Milljet’ (k-64434), ‘SW Estrad’ (k-64435), ‘SW Vinjet’ (k-64436), ‘Zebra’ (k-64707), ‘SW Kungsjet’ (k-66036), ‘SW Kronjet’ (k-66097) and ‘Boett’ (k66353) demonstrated adult and seedling resistance in the period from 2005 to 2019
