Purpose. We show the main directions of work of the West Siberian archaeological detachment (team) of the Institute of Archaeology and Ethnography SB RAS, demonstrate the methods used and present the results and the possibilities of their interpretation. Results. In 2018, the West Siberian archaeological detachment celebrates the 45th anniversary of its formation. The long-term head of the team is academician V. I. Molodin. All studies are carried out within the framework of a multidisciplinary approach starting from the search for archaeological objects (sites Tartas-1, Vengerovo-2, -2A, -6, Staryi Tartas-5, Ust’-Tartas-1,-2; Chicha-1, Vengerovo-6 and others) to their laboratory investigation. We widely apply a range of analytical methods in all of our activities including almost all stages of research: from the search for archaeological sites to their processing in close cooperation with various scientists. We collaborate with specialists from the Institute of Geology and Mineralogy SB RAS, Novosibirsk, Russia; the Institute of Petroleum Geology and Geophysics SB RAS, Novosibirsk, Russia; the Institute of Solid State Chemistry and Mechanochemistry SB RAS, Novosibirsk, Russia; the Institute of Cytology and Genetics SB RAS, Novosibirsk, Russia; the Institute of Nuclear Physics SB RAS, Novosibirsk, Russia; Novosibirsk National Research State University, Novosibirsk, Russia; the Center of Collective Use (CCU) “Geochronology of Cenozoic”, Novosibirsk, Russia; Heidelberg University, Heidelberg, Germany; Ludwig-Maximilian Munich Institute, Munich, Germany; the Center of Archaeology of Kurt Engelhorn, Mannheim, Germany and others. Conсlusion. Studies of the West Siberian archaeological detachment, which were carried out over the recent two decades, have provided new data that develop existing points of view, clarify existing concepts or allow to build new concepts of historical and cultural processes. It is obvious that the modern paradigm of science requires participation of specialists in natural sciences at all stages of archaeological research.

The article examines the role and place of the Mystery within the structure of Mamleev’s metaphysics. The author of the article implicates the concept of “chaosmos’’, introduced by James Joyce in the experimental novel “Finnegans Wake”, to the Mamleev’s Universe. This leads to the transformation of the formula “chaos – osmosis – cosmos”, actualized by postmodern discourse, into the formula “Chaos – Osmosis – Cosmos”. Chaos here is Sacred Chaos, being one of the metaphysical manifestations of Eternal Russia. Osmosis appears to be an antinomic Russian life, which combines the incompatible, and sets itself fundamentally impossible tasks. The Сosmos brings us to the tradition of Russian cosmism with its problem of microcosm and macrocosm conformity. The author of the article points out that the all-pervading and unifying element of Mamleev’s chaos is the Mystery. It is one of the five key metathemes of Mamleev’s oeuvre. The particularity of the Mystery is that it provides a link between other metathemes: utrism “I”, Death, the Abyss and Russia. In the plane of utrism “I” the Mystery is seen as the mystery of man (his higher “I”). The Mystery is related to Death by the person’s interest of his own destiny and finiteness. The problem of overcoming death and the passion for eternal life are the central themes that concern almost all the heroes of Mamleev’s novels and short stories. For Mamleev they are the source of values aimed at the human need to achieve a higher “I”. The connection between the Mystery and the Abyss, as well as the connection between the Mystery and Russia are the strongest and the most important for Mamleev. Consideration of these connections prompts the author to conclude that Yuri Mamleev describes such dimensions of the Mystery, which go beyond the categories “unfathomable-to-us” and “unfathomable-in-itself”, introduced by S. Frank. This requires the introduction of new concepts that would bring out the essence of Mamleev’s innovations. The author of the article proposes to consider the Abyss as a “Last Mystery” by the fact it is transcendent to the transcendents themselves, that is it goes beyond the Absolute, as well as to consider Eternal Russia as a Russia-Mystery on the grounds that Mamleev gives it the status of the third metaphysical Beginning, along with the Absolute and the Abyss.

Abstract From 1909, Stravinsky manifested a keen interest in composing theatre music, as proves the many and various dedicated scores. Almost all of his large works, from the ballet The Firebird (1909-10) to the one-act opera buffa Mavra (1921-22), are written for the stage. Stravinsky thus worked most of the time with scenic presentations, with questions on movement, dance, gestures or scenic tableaus. He develops a particular theatrical instinct: his works have a good scenic orientation, and the correlation with modernism and the new currents in theatre aesthetics is more than obvious. Critics have already analysed and discussed the parallels with such contemporary theatrical concepts as by Bertold Brecht (1898-1956) or Vsevolod Meyerhold (1874-1940). After three great ballets, whose new conception by Stravinsky and Sergei Diaghilev (1872-1929) brought about a fundamental revolution in dance aesthetics, the composer crystallises his notion of incidental music. The aesthetics of L’Histoire du soldat, a work “to be read, played and danced”, is opposed to that of Richard Wagner (1813-83) and his Gesamtkunstwerk (a work blending various arts, a total work of art): a new artistic idea, frozen in gesture and movement, compressed, finding its concentrated expression. Stravinsky establishes a brilliant draft of the issues of Opera, to which he would from now on dedicate himself. Stravinsky’s theatre music reveals a tendency to introduce new concepts in the works written between Sacre du printemps and Pulcinella. A quick look at his stage works before and after L’histoire is necessary in order to fit it in his artistic view.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).

In attempting to use the SEM to investigate the transition from the vegetative to the floral state in oat (Avena sativa L.) it was discovered that the procedures of fixation and critical point drying (CPD), and fresh tissue examination of the specimens gave unsatisfactory results. In most cases, by using these techniques, cells of the tissue were collapsed or otherwise visibly distorted. Figure 1 shows the results of fixation with 4.5% formaldehyde-gluteraldehyde followed by CPD. Almost all cellular detail has been obscured by the resulting shrinkage distortions. The larger cracks seen on the left of the picture may be due to dissection damage, rather than CPD. The results of observation of fresh tissue are seen in Fig. 2. Although there is a substantial improvement over CPD, some cell collapse still occurs.Due to these difficulties, it was decided to experiment with cold stage techniques. The specimens to be observed were dissected out and attached to the sample stub using a carbon based conductive paint in acetone.

Plasma Spraying Process

Plasma spraying is a technique which is used to apply coatings to metallic substrates for a variety of purposes, including hardfacing, corrosion resistance and thermal barrier applications. Almost all of the applications of this somewhat esoteric fabrication technique involve materials in hostile environments and the integrity of the coatings is of paramount importance: the effects of process variables on such properties as adhesive strength, cohesive strength and hardness of the substrate/coating system, however, are poorly understood.Briefly, the plasma spraying process involves forming a hot plasma jet with a maximum flame temperature of approximately 20,000K and a gas velocity of about 40m/s. Into this jet the coating material is injected, in powder form, so it is heated and projected at the substrate surface. Relatively thick metallic or ceramic coatings may be speedily built up using this technique.

One of the most important requirements for a high-performance EM, especially an analytical EM using a fine beam probe, is to prevent specimen contamination by providing a clean high vacuum in the vicinity of the specimen. However, in almost all commercial EMs, the pressure in the vicinity of the specimen under observation is usually more than ten times higher than the pressure measured at the punping line. The EM column inevitably requires the use of greased Viton O-rings for fine movement, and specimens and films need to be exchanged frequently and several attachments may also be exchanged. For these reasons, a high speed pumping system, as well as a clean vacuum system, is now required. A newly developed electron microscope, the JEM-100CX features clean high vacuum in the vicinity of the specimen, realized by the use of a CASCADE type diffusion pump system which has been essentially improved over its predeces- sorD employed on the JEM-100C.

Although the physiological significance of the gap junction remains unspecified, these membrane specializations are now recognized as common to almost all normal cells (excluding adult striated muscle and some nerve cells) and are found in organisms ranging from the coelenterates to man. Since it appears likely that these structures mediate the cell-to-cell movement of ions and small dye molecules in some electrical tissues, we undertook this study with the objective of determining whether gap junctions in inexcitable tissues also mediate cell-to-cell coupling.To test this hypothesis, a coupling, human Lesh-Nyhan (LN) cell was fused with a non-coupling, mouse cl-1D cell, and the hybrids, revertants, and parental cells were analysed for coupling with respect both to ions and fluorescein and for membrane junctions with the freeze fracture technique.

X-ray microanalysis and Convergent Beam Electron Diffraction (CBD) studies were conducted to characterize the second phase particles in two commercial aluminum alloys -- 7075 and 7475. The second phase particles studied were large (approximately 2-5μm) constituent phases and relatively fine ( ∼ 0.05-1μn) dispersoid particles, Figures 1A and B. Based on the crystal structure and chemical composition analyses, the constituent phases found in these alloys were identified to be Al7Cu2Fe, (Al,Cu)6(Fe,Cu), α-Al12Fe3Si, Mg2Si, amorphous silicon oxide and the modified 6Fe compounds, in decreasing order of abundance. The results of quantitative X-ray microanalysis of all the constituent phases are listed in Table I. The data show that, in almost all the phases, partial substitution of alloying elements occurred resulting in small deviations from the published stoichiometric compositions of the binary and ternary compounds.

Scanning Electron

With the development of scanning electron microscope (SEM) with ultrahigh resolution, SEM became to play an important role in not only cytology but also molecular biology. However, the preparation methods observing tiny specimens with such high resolution SEM are not yet established.Although SEM specimens are usually coated with metals for getting electrical conductivity, it is desirable to avoid the metal coating for high resolution SEM, because the coating seriously affects resolution at this level, unless special coating techniques are used. For avoiding charging effect without metal coating, we previously reported a method in which polished carbon plates were used as substrate. In the case almost all incident electrons penetrate through the specimens and do not accumulate in them, when the specimens are smaller than 10nm. By this technique some biological macromolecules including ribosomes, ferritin, immunoglobulin G were clearly observed.Unfortunately some other molecules such as apoferritin, thyroglobulin and immunoglobulin M were difficult to be observed only by the method, because they had very low contrast and were easily damaged by electron beam.
