Afghanistan＇s Military-Political Situation and Regional Security

引用

Contemporary International Relations 2012年第C期22卷 50-51页

作者： Vladimir ivanenko Mr. Vladimir ivanenko is a Senior Researcher at the Russian Institute for Strategic Studies.

NATO＇ s ＂Operation Enduring Freedom＂ was launched in 2001 under the guise of the fight against terrorism and it is still the defining factor in Afghanistan today. This operation has resulted in more than 10 years of war and a substantial increase in terrorism and drugs production in Afghanistan. An agreement on strategic cooperation between Washington and Kabul aims to create a series of long-term American military bases in Afghanistan even after the withdrawal of U.S. troops planned for 2014.

New methods for processing and interpreting marine magnetic anomalies:Application to structure,oil and gas exploration,Kuril forearc,Barents and Caspian seas

引用

Geoscience Frontiers 2013年第1期4卷 73-85页

作者： A.M.Gorodnitskiy Yu.V.Brusilovskiy A.N.ivanenko A.M.Filin N.A.Shishkina Shirshov Institute of Oceanology MoscowRussia

New methods are presented for processing and interpretation of shallow marine differential magnetic data, including constructing maps of offshore total magnetic anomalies with an extremely high reso- lution of up to 1-2 nT, mapping weak anomalies of 5-10 nT caused by mineralization effects at the contacts of hydrocarbons with host rocks, estimating depths to upper and lower boundaries of anom- alous magnetic sources, and estimating thickness of magnetic layers and boundaries of tectonic blocks. Horizontal dimensions of tectonic blocks in the so-called ＂seismic gap＂ region in the central Kuril Arc vary from 10 to 100 km, with typical dimensions of 25-30 km. The area of the ＂seismic gap＂ is a zone of intense tectonic activity and recent volcanism. Deep sources causing magnetic anomalies in the area are similar to the ＂magnetic belt＂ near Hokkaido. In the southern and central parts of Barents Sea, tectonic blocks with widths of 30-100 kin, and upper and lower boundaries of magnetic layers ranging from depths of 10 to 5 km and 18 to 30 km are calculated. Models of the magnetic layer underlying the Mezen Basin in an inland part of the White Sea-Barents Sea paleorift indicate depths to the lower boundary of the layer of 12-30 km. Weak local magnetic anomalies of 2-5 nT in the northern and central Caspian Sea were identified using the new methods, and drilling confirms that the anomalies are related to concentrations of hydrocarbon. Two layers causing magnetic anomalies are identified in the northern Caspian Sea from magnetic anomaly spectra. The upper layer lies immediately beneath the sea bottom and the lower layer occurs at depths between 30-40 m and 150-200 m.

研究磷酸钛离子交换剂(Li-TiOP)在饱和LiNO_(3)溶液中对Cu^(2+)、Co^(2+)、Mn^(2+)、Ni^(2+)和Cr^(3+)离子的吸附性能。采用XRD、SEM、TG、DSC、NGSP和元素分析对固体样品进行表征。采用原子吸收光谱法(AAS)和电感耦合等离子体质谱法(ICP MS)测定溶液中离子的浓度。采用Langmuir、Freundlich、Temkin和Nikolsky模型计算金属离子的吸附等温线。在研究金属离子吸附时,必须考虑吸附剂的溶剂化状态。Li-TiOP对所研究离子的选择性为:Cr^(3+)>Cu^(2+)>Mn^(2+)>Co^(2+)>Ni^(2+),且对上述4种模型均适用。吸附过程热力学参数的变化与吸附剂离子电位的变化有关。磷酸钛能有效去除多组分溶液中的微量金属离子,使LiNO_(3)纯度高于99.999%(质量分数)。

Relationships between a Thiol-Disulfide System and Liposoluble Antioxidants with Cytogenetic Indices in Humans Exposed to Low Doses Radiation

引用

Engineering（科研） 2013年第10期5卷 62-67页

作者： G. F. ivanenko E. B. Burlakova Russian Academy of Sciences Emanuel Institute of Biochemical Physics Moscow Russia

This work presents the results of biochemical examination of people exposed to irradiation as a result of the Chernobyl catastrophe. In remote period ( in 4, 5, 6 and 7 years) after Chernobyl accident we studied the state of the redox system of glutathione(GSH, GSSG) and the response of the system of essential lipid antioxidants (vitamin E, A) in blood plasma of people of various ages. An analysis of correlations between cytogenetic indices in lymphocytes and levels of reduced glutathione and liposoluble antioxidants in the plasma of peripheral blood in children born after the Chernobyl accident and liquidators is presented. The cumulative doses for the examined group of children received by their mothers from 0.8 to 70 cSv and liquidators received, on average, the highest irradiation doses from 0.1 to 150 cSv. A complex relationship between lipo-and water-soluble antioxidants level in plasma in human population (children living in radionuclide-contaminated regions and the Chernobyl liquidators) exposed to chronic low-level radiation after the Chernobyl accident was demonstrated. The obtained experimental data indicate different responses of the human population water-and fat-soluble antioxidants system to low (from 0.1 to 20 cSv) and high (from 20 to 150 cSv) doses of ionizing radiation.

Journal of Electrical Engineering 2014年第1期2卷 34-38页

作者： Tetiana A. Dontsova Iryna M. ivanenko Igor M. Astrelin Svitlana V. Nagimyak Department of Chemistry National Technical University of Ukraine “KPI” Kyiv 03056 Ukraine

Surface of oxidized multiwalled carbon nanotubes was investigated for stabilization of nanosized tin（IV） oxide. The synthesis of nanosized tin（IV） oxide on the surface of carbon nanotubes was carried out with the use of three soft chemical methods： sol-gel, precipitation, and thermal. The synthesized tin（IV） oxide particles on the surface of carbon nanotubes were studied by thermal analysis, X-ray diffraction and electron microscopy. The lattice parameters of tin（IV） oxide on the surface of multiwalled carbon nanotubes were calculated.
