‘Nordicity’, ‘Imagined North’ or ‘Concept Sphere of Arctic Discourse’?

The relevance of the study is due to the fact that the Arctic is a unique northern territory of the globe, interest in which has recently increased due to geopolitical reasons, its natural resources and the cultural diversity of the peoples inhabiting it. The question of the content of the terms ‘Nordicity’, ‘imagined / imagination of the North’ in the works of foreign and Russian scientists in the humanities is raised in the article. It is revealed that these terms are associated with an ensemble of concepts and discourses united by the themes of the North and the Arctic, objectified in cultural texts: both verbal and non-verbal. The hypothesis that these terms are equivalent in content and structure to the term ‘concept sphere of discourse’, adopted in Russian linguistics is substantiated in the article. The novelty of the study is seen in the fact that the definition of the terms ‘Arctic discourse’ and ‘the concept sphere of the Arctic discourse’ is proposed. ‘The Arctic discourse’ is defined as a complex discourse representing a set of cultural texts united both by the Arctic and by a broader northern theme; its sign correlates can be various socio-cultural practices. ‘The concept sphere of Arctic discourse’ is understood as a set of concepts and images in a complex Arctic discourse dedicated to the representation of the Arctic as a geopolitical and geocultural space

ЗАХИСТ КАРТОПЛІ ВІД ШКІДЛИВИХ ОРГАНІЗМІВ

The Colorado potato beetles and aphids are especially harmful pests for potato crops in the conditions of Kyiv region. So, on the 10th day after mass rebirth of the Colorado potato beetle larvae, potato plants on untreated by insecticide plots were completely destroyed by this phytophagus. Preplanting insecticide treatment of potato tubers provided high effectiveness against the Colorado potato beetle prior to the mass rebirth and development of larvae and reduced their density of population and harmfulness. The highest efficacy (93.2-95.2%) against these pests was noted in variants with Prestige, 290 FS, Emesto Quantum 273.5 FS and Celest Top 312.5 FS. Common scab, dry rot and Rhizoctonia solani were prevailed among the diseases of potato tubers. The greatest effectiveness against the common scab was provided by Prestige, 290 FS. Thus, the infestation of potato tubers by common scab in the variant with application of the Prestige, 290 FS was almost twice lower compared to control. Preparation Celest Top 312.5 FS provided a reduction of dry rot in almost 3 times, and Emesto Quantum 273.5 FS leads to reduction of infestation by Rhizoctonia solani in 4 times, respectively. The treatment of tubers is a reliable protection of potato plants against damage by the Colorado potato beetles and lesion diseases, that made it possible to obtain tuber yields at a level of 24.4-27.4 t per ha. However, preplanting treatment of planting material with insecticides is not always able to provide the protection of potato seedlings against damage by Colorado beetles. The mass reproduction of these pests occurs after planting of tubers and emerging of stalks at high air temperatures. Therefore, it is necessary to provide additionally spraying of plants. Typically, the insecticides used in recommended rates have a long period of protective action, which eliminates the need for further treatments on vegetative plants. The anti-resistant effect of this treatment is associated with the use of the neonicotinoids class insecticides (eg, imidacloprid, thiamethoxam, clothianidin), that have different mechanism of action compared to pyrethroids. Under such conditions, it is important to search, investigate and introduce modern, effective insecticides into agricultural production. For this purpose the research on the preparations from separate classes of chemical compounds with various toxic properties was conducted. The most effective against the larvae of Colorado potato beetles were insecticides Confidor, 20% SC, Calypso, 48% SC and Engeo 24.7% SC when spraying potato plantings. Duration of their protection was prolonged for two weeks after the application of insecticides. The maximum technical efficiency was reached as 99.5% (Confidor, 20% SC), 99.2% (Calypso, 48% SC) and 99.3% (Engeo 24.7% SC) on the third day after application. Other insecticides such as Mospilan, 20% SP and Actara, 24% WG (96.2-97.0%) provided somewhat lower the mortality rate of these phytophages. The highest and prolonged effect against aphids was obtained by spraying potato plantings with the preparations Engeo 24.7% SC and Confidor, 20% SC, the efficiency of which reached 98.2% and 93.1%, that decreased the number of aphids in almost 60 times, compared with the control. Spraying potato plantings with insecticides according to the recommended rates of application allows obtaining the yield of tubers at the level of 25,6-28,2 t per ha.    У статті наведені результати ефективності інсектицидів різних хімічних класів проти основних шкідників картоплі.

Gene Expression Atlas update—a value-added database of microarray and sequencing-based functional genomics experiments

Gene Expression Atlas (http://www.ebi.ac.uk/gxa) is an added-value database providing information about gene expression in different cell types, organism parts, developmental stages, disease states, sample treatments and other biological/experimental conditions. The content of this database derives from curation, re-annotation and statistical analysis of selected data from the ArrayExpress Archive and the European Nucleotide Archive. A simple interface allows the user to query for differential gene expression either by gene names or attributes or by biological conditions, e.g. diseases, organism parts or cell types. Since our previous report we made 20 monthly releases and, as of Release 11.08 (August 2011), the database supports 19 species, which contains expression data measured for 19 014 biological conditions in 136 551 assays from 5598 independent studies

A change in the optical polarization associated with a gamma-ray flare in the blazar 3C 279

It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet pointing close to our line of sight. The size of the emitting zone and the location of this region relative to the central supermassive black hole are, however, poorly known, with estimates ranging from light-hours to a light-year or more. Here we report the coincidence of a gamma-ray flare with a dramatic change of optical polarization angle. This provides evidence for co-spatiality of optical and gamma-ray emission regions and indicates a highly ordered jet magnetic field. The results also require a non-axisymmetric structure of the emission zone, implying a curved trajectory for the emitting material within the jet, with the dissipation region located at a considerable distance from the black hole, at about 10^5 gravitational radii.Comment: Published in Nature issued on 18 February 2010.

AGILE detection of a rapid γ-ray flare from the blazar PKS 1510-089 during the GASP-WEBT monitoring

We report the detection by the AGILE satellite of a rapid gamma-ray flare from the powerful gamma-ray quasar PKS 1510-089, during a pointing centered on the Galactic Center region from 1 March to 30 March 2008. This source has been continuosly monitored in the radio-to-optical bands by the GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT). Moreover, the gamma-ray flaring episode triggered three ToO observations by the Swift satellite in three consecutive days, starting from 20 March 2008. In the period 1-16 March 2008, AGILE detected gamma-ray emission from PKS 1510-089 at a significance level of 6.2-sigma with an average flux over the entire period of (84 +/- 17) x 10^{-8} photons cm^{-2} s^{-1} for photon energies above 100 MeV. After a predefined satellite re-pointing, between 17 and 21 March 2008, AGILE detected the source at a significance level of 7.3-sigma, with an average flux (E > 100 MeV) of (134 +/- 29) x 10^{-8} photons cm^{-2} s^{-1} and a peak level of (281 +/- 68) x 10^{-8} photons cm^{-2} s^{-1} with daily integration. During the observing period January-April 2008, the source also showed an intense and variable optical activity, with several flaring episodes and a significant increase of the flux was observed at millimetric frequencies. Moreover, in the X-ray band the Swift/XRT observations seem to show an harder-when-brighter behaviour of the source spectrum. The spectral energy distribution of mid-March 2008 is modelled with a homogeneous one-zone synchrotron self Compton emission plus contributions from inverse Compton scattering of external photons from both the accretion disc and the broad line region. Indeed, some features in the optical-UV spectrum seem to indicate the presence of Seyfert-like components, such as the little blue bump and the big blue bump

КОНТРОЛЬ ЧИСЕЛЬНОСТІ ШКІДНИКІВ ТОМАТІВ ЗА УМОВ КРАПЛИННОГО ЗРОШЕННЯ

The relevance of the research. The application of insecticides when applying drip irrigation is reasonable for the protection of tomatoes, grown in arid regions of southern Ukraine, against pests, in particular against the Colorado potato beetle. When cultivating these crops, farmers should follow the operation manual for chemicals use, which indicates the optimal time of insecticide application during the irrigation cycle. Methods of the research. The use of insecticides along with drip irrigation in the form of local injections provides high efficiency in the larvae of the Colorado potato beetle control and prolongs a toxic effect of the chemically active ingredients compared to the common spraying method. Research investigation of the insecticides effectiveness against the Colorado potato beetle was carried out on Tomato sorts Lagidny, Kremenchugskiy. Insecticides were used in different ways: common spraying and applying with drip irrigation. Research results. The greatest effectiveness against the Colorado potato beetle on 7th day after insecticides applying was noted on the variants Engeo 24.7% SC (93.1%), Coragen (91.9%) and Voliam Flexi 300 SC (90.3%). The highest efficacy was provided by the combined insecticide Voliam Flexi 300 SC (94.2%) that was applied with drip irrigation. Introduction of insecticides Voliam Flexi 300 SC, Confidor, 20% SL, Mospilan, 20% SP, Calypsо, 48 % SC and Actara 240 SC with water by drip irrigation ensured their high efficiency during 21 days or more, excluding the need for their repeated application. Conclusions. The use of insecticides along with drip irrigation is a perspective area in plant protection and can be successfully used to control various insect pests of vegetable crops. Since many vegetable growers already use drip irrigation, it is easy and convenient to introduce pesticides in their irrigation systems by adding a pump for injection and the necessary equipment for the introduction of soluble pesticides (switches, check valves, etc.).Дослідження ефективності інсектицидів проти колорадського жука проводили на сортах томатів Лагідний, Кременчуцький.

Electrophysical properties and transfer function of the vestibular labyrinth

An experimental and theoretical study of electrical conductive properties of the vestibular labyrinth tissues is carried out. Using the theory of dynamic systems and experimental data on the measurements of amplitudes of electrical signal at the end of the vestibular nerve, the transfer function of the vestibular labyrinth is calculated and its frequency dependence is investigated. It is shown that the transfer function tends to its asymptotic value with increasing frequency. It is found that the transfer function of the vestibular labyrinth for stimulating impulses emanating from the electrode located in the posterior semicircular canal is significantly less than that for stimulating impulses from electrodes located in the superior and horizontal semicircular canals
