Plasma dynamic synthesis of ultradispersed copper oxides

Copper oxide is necessary material for production of superconductors. The issue of obtaining high purity and nanosides CuO is actual. This article shows the results on the obtaining of nanodispersed copper oxide by plasma dynamic method in system based on coaxial magneto plasma accelerator with copper electrodes. Such analyses of ultradispersed synthesized products as X-Ray diffractometry, IR-spectroscopy and thermal analysis were carried out. According to XRD such phases as copper Cu, copper oxide (I) Cu[2]O, copper oxide (II) CuO, and copper hydroxide hydrate Cu(OH)[2]xH[2]O were identified in the product. It was found that with the gradual heating of the initial product up to 800°С the phase content changed dramatically in terms of enhancing copper oxide phase (up to 97%)

Constitutional and Legal Regulation of State Authority Interaction on Citizen Appeals: Foreign Experience

The purpose of this article is to identify the foreign experience of constitutional legalization of the basic foundations of interaction between government bodies regarding citizens' appeals. The study was built based on a dialectical approach to the disclosure of legal phenomena and processes using general scientific (systemic, logical, analysis and synthesis) and private scientific methods. The claimed interaction becomes relevant in modern conditions because that there is the coordination of the interests between an individual and the state in this process that is demanded to strengthen democratic values. Systematization of foreign constitutional experience, which appears in the comparative legal aspect as part of the general human rights theory

Possibility of obtaining TiO2 material by plasma dynamic method into an air atmosphere

Using the X-ray diffractometry it is shown that the obtained product contains two main crystalline phases: anatase and rutile with tetragonal syngony. The size of the coherent scattering region is less 100 nm

Comparing predation on forest grouse nests by avian and mammalian predators in two contrasting boreal forest landscapes by the use of artificial nests

The article can also be located on the Ornis Fennica webpage: http://www.ornisfennica.org/index.htmEgg predation is an important determinant of breeding success among boreal forest grouse, but the relative roles ofmammalian and avian predators are poorly known. During spring/early summer of 2010, predation on artificial nests was studied by placing nests on the ground and on 1.5-m tall poles at two forested areas. One study site was highly fragmented due to intensive forestry (Varaldskogen, Norway) and the other site was a pristine, natural forest in north-western Russia (Pinega Forest Reserve). The nests on poles were subject to predation by birds and those on the ground by both mammals and birds. Total predationwas significantly higher inVaraldskogen than in Pinega. Ground nests suffered ca. 2.5 times higher losses than nests on poles. In Pinega, predation did not differ between the two nest types. The difference between the two areas was probably due to different predator guilds:mammalian generalist predators, such as theRed Fox (Vulpes vulpes) and Badger (Meles meles), were common in Varaldskogen but scarce or absent in Pinega. Canopy cover explained most of the variation in predation rate in Varaldskogen, but no significant relationship with canopy or nest concealment was detected in Pinega. Predation on pole nests varied across habitat types in a similarmanner at the two areas, but predation on ground nests did not. As Raven (Corvus corax) and Hooded Crow (Corvus corone cornix)were rare in both areas, these findings suggest similar searching and predatory behaviour of the two main (smaller) corvids, the Eurasian Jay (Garrulus glandarius) in Varaldskogen and the Siberian Jay (Perisoreus infaustus) in Pinega. Although the study design allowed a comparison between avian andmammalian nest predators, the lack of a clearer relationship between predation and certain variables suggests that nest predation is a complex process involving components of predator behaviour

Riistaeläinten populaatioiden dynamiikka Pohjois-Euroopassa: tiivistelmä : 7. kansainvälinen symposium. 24. – 28. Syyskuuta

We have studied Black Grouse population abundance and its dynamics in large regions of North-Europe and Urals’ taiga (Finland, Russian Karelia, Murmansk, Arhangel, Kirov and Komi regions and). The data is based on Winter Track Counts (WTC, Priklonski, 1973), where all grouse sightings are recorded. We also studied the longterm Black Grouse abundance changes in Russian and Belarus Natural Reserves (by “Chronical of Natural” Programme, including summer counts of forest grouses): Pinezhsky, Pechoro-Ilychskiy, National Park "Mechera", Nature Reserve "Kivach", "Bryansk Forest", Kostomuksha Nature Reserve Volzhsko-Kamsky National Nature Biosphere Reserve and Visimskiy State Nature Reserves. The highest and most stable abundances of Black Grouse were recorded from East Fennoscandia (Karelia – 3.6 birds per 10 km; Finland – 4.4, coefficient of variation – 12% and 27%, respectively), whereas in the Murmansk and Arkhangelsk Regions and Komi republic, e.g. the species abundance indices were 0.5, 2.5 and 1.1 birds per 10 km, respectively. The “Peak” and minimal abundance years do not concur in different regions of north-European taiga. In Komi in the period from 2001 to 2013, the number of the black grouse declined twice, in Arhangel in the period 30 years – decreased fivefold. In Tatarstan Republic (Volzhsko-Kamsky National Nature Biosphere Reserve) after 1980 abundance decreased rapidly and at last 10 tears – disappeared. In Central Siberia BG are small in numbers and rare. The data suggest Black Grouse abundance varies significantly across Northern Eurasia and among years. One may presume there are some factors acting in different directions: towards convergence and towards divergence of the trends.Peer reviewe

Механизмы нарушений эритропоэза при сепсисе

Objective: to determine the mechanisms responsible for impairments in the space-time organization of erythropoiesis (SPOE) in experimental sepsis. Materials and methods. The diurnal changes in the titer of erythropoietin, the content of red blood cells, and their distribution by volume, the peripheral blood levels of hemoglobin and reticulocytes, life span, the production of erythrocytes, malonic dialdehyde (MDA), the statokinetic erythroid cell index, and bone marrow 59Fe incorporation were studied in 240 Wistar rats with multimicroial sepsis and 80 intact animals. Results. In sepsis, SPOE desynchronism was found to be due to increases in MDA and in the population of microcytes with shorter life span. The maximum duration was increased for erythropoiesis and decreased for erythrocytic production with the decreased peripheral blood level of ery-throcytes and hemoglobin. The progressive rise in the titer of erythropoiesis was accompanied by decreases in the statoki-netic index and bone marrow 59Fe incorporation with a simultaneous increase in the population of microcytes and with a reduction in the life span of erythrocytes. Conclusion. Endotoxicosis was established to play the leading role in the mechanisms of SPOE desynchronism. Activation of lipid peroxidation in the red blood cell membranes enhances their rigidity, by initiating the development of anemia and microcirculatory disorders. The decreases in erythrocytic production, statokinetic index, and bone marrow 59Fe incorporation with an inadequately high titer of erythropoiesis suggest the inhibition of ery-thropoietin-dependent processes in the target cells, which promotes the progression of septic anemia. Key words: bio-rhythms, erythropoiesis, erythropoietin, anemia, sepsis.Цель исследования — определить механизмы нарушения пространственно-временной организации эритропоэза при экспериментальном сепсисе. Материал и методы. У 240 крыс Вистар с полимикробным сепсисом и 80 интактных животных изучена суточная динамика титра эритропоэтина, содержания эритроцитов и их распределения по объему, гемоглобина и ретикулоцитов в периферической крови, продолжительности жизни и продукции эритроцитов, малонового диальдегида, статмокинетического индекса эритроидных клеток и инкорпорации Fe59 костным мозгом. Обнаружено, что при сепсисе десинхроноз ПВОЭ обусловлен ростом МДА и популяции микроцитов с укороченной продолжительностью жизни. Продолжительность максимума для эритропоэза увеличена, для продукции эритроцитов — сокращена на фоне снижения уровня эритроцитов и гемоглобина в периферической крови. Прогрессирующий рост титра эритро-поэза сопровождается снижением статмокинетического индекса и инкорпорации Fe59 костным мозгом при одновременном увеличении популяции микроцитов и сокращении продолжительности жизни эритроцитов. Заключение. Установлено, что в механизмах десинхроноза ПВОЭ ведущая роль принадлежит эндотоксикозу. Активация процессов липопероксидации в мембранах эритроцитов повышает их ригидность, инициируя развитие анемии и нарушения микроциркуляции. Снижение продукции эритроцитов, статмокинетического индекса и инкорпорации Fe59 костным мозгом на фоне неадекватно высокого титра эритропоэза свидетельствует о торможении эритропоэтинзависимых процессов в клетках-мишенях, что способствует прогрессии септической анемии. Ключевые слова: биоритмы, эритропоэз, эритро-поэтин, анемия, сепсис
