Far Eastern Federal University is an institution of higher education located in Vladivostok, Russia. Established in 1899, the university was closed in the late 1930s under Joseph Stalin, and reopened in 1956, two years after Nikita Khrushchev visited Vladivostok. The university is going to be reorganized in the near future to form the core of the Far Eastern Federal University with new campus on the Russky Island south of Vladivostok. The campus is currently under development and its buildings will serve as facilities for 2012 APEC summit in Vladivostok.Formerly named Far Eastern State University, the university officially changed its English name in 2000 into Far Eastern National University. References to the university under its old name are common. Wikipedia.

Objectives: Numerous elderly patients with overactive bladder (OAB) demonstrate insuffcient treatment results under antimuscarinic monotherapy with dose increase. To reduce the OAB symptoms and to estimate safety and tolerability of non-invasive treatment, we evaluated the use of combined antimuscarinics as the alternatives. Methods: Eighty-one patients older than 65 years, both male and female, who earlier received (for 6 months or more before our study) double-dose antimuscarinic monotherapy (trospium), whose initial symptoms did not resolve (or the improvement was short lived), and who experienced mild or no side effects, were included in this study. The patients demonstrated urodynamic-proven overactive bladder with daily incontinence, increased intravesical pressure, and reduced bladder capacity. Taking into account the strength of the initial study treatment, they were distributed into 3 groups and treated with 2 antimuscarinics. The patients underwent urodynamic examination before enrollment in the sixth week and in the fourth month. During the whole treatment period, they kept special bladder diaries where they, among other issues, described side effects during treatment. results: Significant changes were noted at the 6-week follow-up in all 3 groups. The average number of daily incontinence events decreased from 6 to 2 events. The average maximum bladder capacity (177 to 356 mL) and refex volume (149 to 284 mL) increased; detrusor compliance also improved (average, 16 to 37 mL/cm H2O). Twenty-four patients reported side effects; 3 of them discontinued the successful treatment due to this reason. Seven other patients did not receive any noticeable improvement of detrusor dysfunction, although they did not report any side effects. conclusion: The majority of elderly patients, who previously demonstrated unsatisfactory results under dose-escalated monotherapy, were treated successfully with combined high-dosage antimuscarinics (87.6%). The quantity of side effects was comparable to that of normal-dosed antimuscarinics. take-Home Message: The majority of elderly patients, who continued to suffer from symptoms of overactive bladder after dose-escalated antimuscarinic monotherapy, showed subjective and objective treatment success. The therapy used the combination of high-dosed antimuscarinics (87.6%). Obtained side effects were comparable to (did not exceed) the single-drug treatment. ©2013 Digital Science Press, Inc.

The invention relates to the field of small-scale power generation and can be used to produce wind farms. The wind power plant comprises blades mounted on an annular pontoon. The pontoon is rotatable about a vertical axis. An energy converter, capable of converting rotational energy, is situated on a platform that is encircled by the annular pontoon. A kinematic mechanism is designed so as to be capable of transmitting the rotational energy of the annular pontoon to the receiving unit of the energy converter. The floating platform is equipped with positioning means that include at least six anchors located on the bottom of a body of water. The anchors are connected to the platform by flexible members and are offset in a direction opposite to the direction of rotation of the annular pontoon relative to the point at which the flexible member is attached to the platform. The technical result is an increase in the number of places where the wind power plants can be installed and an increase in electric power generation.

To determine the optical sign of an investigated crystal plate, a conoscopic pattern of the latter is changed in an optical system without a polarizing microscope. To change the conoscopic pattern, an auxiliary plane-parallel crystal plate of arbitrary thickness and known optical sign is used. Such a plate, which is either capable of rotation about its vertical axis or fixed at a small angle to the investigated plate, is introduced into the optical system. Upon rotation of the auxiliary crystal plate, isochromatic rings on the conoscopic pattern are offset. Based on the direction of the offset from the centre of the pattern, a conclusion is drawn about the optical sign of the investigated crystal plate. When the auxiliary crystal plate is fixed at a small angle to the investigated plate, either two or three conoscopic patterns are observed on the screen. The optical sign of the investigated crystal plate is determined by the number of conoscopic patterns on the screen. If there are three patterns, then the optical signs of the auxiliary and the investigated plates are the same. If there are two patterns, then the optical signs of the auxiliary and the investigated plates are opposite. © 2010 International Union of Crystallography Printed in Singapore-all rights reserved.

During the SoJaBio expedition, the deep sea fauna of the north-western Sea of Japan was sampled in August-September 2010. From this study, 11 epibenthic sledge stations are analyzed, with a focus on species composition, diversity and distribution patterns of polychaetes. A total of 92 polychaete taxa belonging to 70 genera and 28 families and 3 indeterminate species were found. Twelve species and eight genera have not been reported from the Sea of Japan before, but were registered from other deep-sea basins. Calculation of diversity (Shannon-Wiener Index, Pielou's Evenness) showed that the upper bathyal of the Sea of Japan is an area of higher polychaete diversity than the abyssal plain. The increased richness and diversity here could possibly be explained by a zoogeographic overlapping with the shallower species' assemblages of the shelf. At a higher taxonomic level the polychaete fauna of the deep Sea of Japan does not seem to differ from that of other deep-sea regions world-wide. In depths below 2000. m about 30% polychaete species have wide distributional ranges. © 2012 Elsevier Ltd.

Two new nemertean species from the deep-sea, Cephalothrix iwatai sp. nov. and Micrura bathyalis sp. nov., are described and illustrated from material collected in the Sea of Japan during the SoJaBio (Sea of Japan Biodiversity Studies) expedition in the summer 2010. Both species represent the deepest benthic nemerteans reported to date. In addition, the diagnosis of the genus Cephalothrix is modified to accommodate recent data on cephalotrichid morphology. © 2012 Elsevier Ltd.


Results of determinations of proton magnetic relaxation time (T 1) in the liquid phase of frozen sea water at temperatures between -2°C and -38°C, with variable rate and direction of temperature change, are presented. Temperature hysteresis corresponding to the crystallization range of certain sea-water salts, mainly NaCl which partially precipitates as the crystalline hydrate NaCl·2H2O at temperatures below -23°C, is detected in the temperature dependence of T1, as in the analogous dependence of brine content. It is shown that formation of crystalline hydrates in brine is preceded by complete solvation of ions at -5 to -6°C. The main causes of hysteresis in temperature dependence of T1 and the extension of loop limits compared with the analogous loop for liquid brine content are indicated. Additional potentialities of using the nuclear magnetic resonance method for investigating sea-ice properties are presented.

The gas flow in the gravity field through the porous objects with heat sources, which may arise from natural or man-caused disasters, is investigated when the object's outlet is partially closed. The mathematical model and original numerical method, based on the combination of explicit and implicit finite difference schemes, are developed for researching the time-dependent regimes of the gas flow through two-dimensional porous objects with heat sources. The influence of partial closure of the object's outlet on the cooling process of the axisymmetric porous objects with a non-uniform distribution of heat sources is analyzed by means of computational experiment. © 2014 Elsevier Ltd.

A mathematical model and a numerical method, based on the combination of explicit and implicit finite difference schemes, have been developed for investigating the unsteady gas flows in porous objects with zones of heterogeneous combustion when gas pressure at object boundaries is known. Used approach enables to solve problems of filtration combustion for both forced filtration and free convection, so it can be efficiently applied for modeling the combustion zones in porous media, which may arise from natural or man-caused disasters. One-dimensional unsteady processes of heterogeneous combustion in porous object under free convection have been investigated using numerical experiment. Two regimes of combustion wave propagation have been revealed-wave movement up and down in the object-and it is shown that these regimes are significantly different in degree of burn of solid combustible material, the temperature in the combustion zone and propagation velocity of combustion wave. © 2012 The Combustion Institute.

In the majority of cases electric spark and arc discharges developed in condensed media result in the formation of micro- or nanosized particles. Micro- or nano-formations of different types are always present on the surface of oxide coatings formed under effect of electric spark and arc discharges (the approach is referred to as the method of plasma electrolytic oxidation (PEO) or microarc oxidation (MAO)). These formations (particles) can be extremely active in physical-chemical terms and determine the properties of a system at large. Nevertheless, the structure, composition, and mechanism of formation of the above micro- and nanostructures and their control on the surface of PEO-coatings of different chemical composition as well as their effect on the functional properties of the systems obtained using the PEO-method have not yet been studied in sufficient detail. The present paper is devoted to the examination of micro- and nano-formations on the surface of PEO-coatings: their shape, composition, and effect on the coatings properties. The objective of the paper was to generalize our earlier obtained data on micro- and nano-formations on the surface of PEO-coating on aluminum and titanium and emphasize the importance of the poorly developed field of knowledge related to PEO-coatings, their structure and formation mechanisms, and the possibilities of controlling their composition and functional properties. © 2013 Elsevier B.V.

During the KuramBio expedition, the abyssal plain adjacent to the Kuril-Kamchatka Trench was sampled in July-August 2012. More than 5200 individuals of Polychaeta belonging to 38 families, 108 genera and about 144 species were found. Six genera have been reported for the Northwest Pacific for the first time. About 50% of the collected polychaete species are considered as new to science. One of these, Sphaerephesia lesliae sp. n., is described herein. The detailed description of the new species is presented and its differences from similar species are shown. This eighth species of the genus is characterized by the presence of macrotubercles with two paired terminal papillae. The genus Sphaerephesia Fauchald, 1972 is newly recorded in the Northwest Pacific. An updated key to the species of the genus Sphaerephesia is provided. © 2014 Elsevier Ltd.
