Changes of melamine–formaldehyde resin (MF-R)particles occurring in complex dusty plasma
have been investigated. Using a specially developed method, plasma-modified MF-R particles have been
extracted from a dust trap after levitation for various periods of time and studied by electron microscopy techniques. Changes in the surface structure of MF-R particles are determined, and quantitative data on the variation in particle dimensions depending on the time of occurrence in plasma are obtained.

An approach providing yttrium-stabilized zirconia coatings deposition on titanium is
suggested. High-quality YSZ coatings with 5-6 m thickness were studied using SEM and XRD,
the mechanical properties (Brenell and Moos hardness) of covered samples were compared
with pure titanium characteristics. The regimes of titanium wafer pretreatment were optimized. It
was shown that both 8Y2O3-92ZrO2 and 9Y2O3-10TiO2-92ZrO2 coatings increase the materialhardness.

dc.description.abstract

value: A new mineral, mendigite (IMA no. 2014-007), isostructural with bustamite, has been found in the In den Dellen pumice quarry near Mendig, Laacher Lake area, Eifel Mountains, Rhineland-Palatinate (Rheinland-Pfalz), Germany. Associated minerals are sanidine, nosean, rhodonite, tephroite, magnetite, and a pyrochlore-group mineral. Mendigite occurs as clusters of long-prismatic crystals (up to 0.1 × 0.2 × 2.5 mm in size) in cavities within sanidinite. The color is dark brown with a brown streak. Perfect cleavage is parallel to (001). D calc = 3.56 g/cm3. The IR spectrum shows the absence of H2O and OH groups. Mendigite is biaxial (–), α = 1.722 (calc), β = 1.782(5), γ = 1.796(5), 2V meas = 50(10)°. The chemical composition (electron microprobe, mean of 4 point analyses, the Mn2+/Mn3+ ratio determined from structural data and charge-balance constraints) is as follows (wt %): 0.36 MgO, 10.78 CaO, 37.47 MnO, 2.91 Mn2O3, 4.42 Fe2O3, 1.08 Al2O3, 43.80 SiO2, total 100.82. The empirical formula is Mn2.00(Mn1.33Ca0.67) (Mn0.50 2+ Mn0.28 3+ Fe0.15 3+ Mg0.07)(Ca0.80 (Mn0.20 2+)(Si5.57 Fe0.27 3+ Al0.16O18). The idealized formula is Mn2Mn2MnCa(Si3O9)2. The crystal structure has been refined for a single crystal. Mendigite is triclinic, space group P1¯; the unit-cell parameters are a = 7.0993(4), b = 7.6370(5), c = 7.7037(4) Å, α = 79.58(1)°, β = 62.62(1)°, γ = 76.47(1)°; V = 359.29(4) Å3, Z = 1. The strongest reflections on the X-ray powder diffraction pattern [d, Å (I, %) (hkl)] are: 3.72 (32) (020), 3.40 (20) (002, 021), 3.199 (25) (012), 3.000 (26), (012¯, 12¯0), 2.885 (100) (221, 21¯1, 12¯1), 2.691 (21) (222, 21¯0), 2.397 (21) (022¯, 211¯, 203, 031), 1.774 (37) (412, 32¯1). The type specimen is deposited in the Fersman Mineralogical Museum, Russian Academy of Sciences, Moscow, registration number 4420/1.

«Комплексное изучение психологических факторов возникновения кризисов
профессионального развития в периоды юности и ранней взрослости»

dc.description.abstract

value:
Данная работа направлена на комплексное изучение психологических факто-
ров возникновения кризисов профессионального развития. Изучены характери-
стики профессионального развития на этапах выбора профессии, профессиональ-
ного обучения в средних профессиональных и высших учебных заведениях и на
начальном этапе профессиональной деятельности. Комплексность исследования
обеспечивалась включением в исследование характеристик профессионального
развития, изучения наличия, степени выраженности и характера кризисных про-
явлений. Мы считали важным также рассмотрение факторов, которые могут спо-
собствовать возникновению кризисов профессионального развития, либо смягчать
кризисные проявления, способствовать их преодолению. В качестве таких факто-
ров были изучены внешние социальные факторы — условия и типы образователь-
ной среды; условия семейного воспитания — состав и структура семьи, ее сплочен-
ность, стили воспитательных воздействий. Большую роль в профессиональном
развитии играют и внутренние, индивидуально-психологические факторы. В каче-
стве таковых были выделены пол, возраст, отношение к выбору профессии, пока-
затели профессионального развития, личностные ресурсы человека. Все эти подхо-
ды мы реализовали в организации исследования. Исследование было выполнено
на выборках старшеклассников, студентов средних и высших профессиональных
учебных заведений, начинающих профессионалах. Общий объем выборки соста-
вил более 1500 человек. Программа исследования охватывает различные аспекты
профессионального функционирования человека как субъекта деятельности и на-
целена на выявление закономерностей профессионального развития человека в со-
отношении с периодами его онтогенетического возрастного развития. В работе по-
следовательно рассматриваются показатели профессионального самоопределения
и развития личности на этапах выбора профессии, получения среднего профессио-
нального и высшего образования (в процессе обучения от первого курса до выпуск-
ного), на этапе начала профессиональной деятельности. Применительно к каждому
из выделенных этапов всесторонне анализируются возникающие кризисы профес-
сионального развития, их источники и факторы возникновения. Помимо этого уде-
ляется внимание рассмотрению ресурсов личности и внешней среды, способствую-
щих предотвращению и успешному преодолению кризисов.

В статье исследуется проблема адекватности отражения в действующем российском уголовном законе общественной опасности деяний, сопряженных с введением в заблуждение потерпевших.
Автор приходит к выводам о том, что в УК РФ недооценена общественная опасность обманных действий, в том числе и различного рода фальсифи-каций:
криминологически необоснованно исключение обмана как возможного способа совершения некоторых преступлений, что нарушает принципы криминализации деяний, дифференциации и индивидуализации уголовной ответственности;
наличие в УК РФ самостоятельного состава обмана (фальсификации) само по себе не решает вопроса об уголовно-правовой защите интересов, способом нарушения которых выступает обман;
законодательную практику усиления ответственности за дополнительные общественно опасные последствия, неизбежно или с высокой вероятностью наступающие в результате обманных действий, следует признать обоснованной. При ее реализации целесообразно рассмотреть вопрос о включении признака наступления тяжких последствий в качестве квалифицирующего, как это сделано в отношении составов преступлений, предусмотренных в ст. 285, 286 УК РФ.

dc.description.abstract

value:
Non-adiabatic transitions from the I2(E0+g, D0+u, β1g and D′2g) states to first tier ion-pair (IP) states induced by collisions with Ar atoms have been investigated. The stepwise laser excitation schemes have been used for selective population of close-lying vibronic states: E, vE = 13, D, vD = 18, β, vβ = 19 and D′2g, vD′ = 23. Rate constants of population of the first tier ion-pair states from the optically populated rovibronic states as well as rate constants of depopulation of the states have been determined. Analysis of the mechanism of the transitions has been carried out.

We find that the 3410 A luminescence band in the case of optical population of the D and β states cannot be described assuming the collision-induced non-adiabatic transitions only. We conclude that there is an additional radiative channel for population of the states, probably, due to the formation of the ArI2(IP) van der Waals complexes.

It has been shown that luminescence from the I2(δ2u) state becomes observable due to interaction between the rovibronic levels of the D0+u and δ2u states described by the nonadiabatic operator Vn of the heterogeneous interaction taken in the second order of the perturbation theory where the main intermediate state contribution is provided by the γ1u state.

title: Wave-function-based embedding potential for ion-covalent crystals

dc.contributor.author

value: Abarenkov, I

value: Boyko, M

dc.description.abstract

value:
Many important properties of crystals are the result of the local defects. However, when one address directly the problem of a crystal with a local defect one must consider a very large system despite the fact that only a small part of it is really essential. This part is responsible for the properties one is interested in. By extracting this part from the crystal one obtains a so-called cluster. At the same time, properties of a single cluster can deviate significantly from properties of the same cluster embedded in crystal. In many cases, a single cluster can even be unstable. To bring the state of the extracted cluster to that of the cluster in the crystal one must apply a so-called embedding potential to the cluster. This article discusses a case study of embedding for ion-covalent crystals. In the case considered, the embedding potential has two qualitatively different components, a long-range (Coulomb), and ashort-range. Different methods should be used to generate different components. A number of approximations are used in the method of generating an embedding potential. Most of these approximations are imposed to make the equations and their derivation simple and these approximations can be easily lifted. Besides, the one-determinant approximation for the
wave function is used. This is a reasonably good approximation for ion-covalent systems with closed shells, which simplifies the problem considerably and makes it tractable. All employed approximations are explicitly stated and discussed. Every component of generation methods is described in details. The proofs of used statements are provided in a relevant appendix.

title: The WEBT campaign on the BL Lac object PG 1553+113 in 2013. An analysis of the enigmatic synchrotron emission

dc.contributor.author

value: Morozova, Daria

dc.description.abstract

value:
A multifrequency campaign on the BL Lac object PG 1553+113 was organized by the Whole
Earth Blazar Telescope (WEBT) in 2013 April–August, involving 19 optical, two near-IR,
and three radio telescopes. The aim was to study the source behaviour at low energies during
and around the high-energy observations by the Major Atmospheric Gamma-ray Imaging
Cherenkov telescopes in April–July. We also analyse the UV and X-ray data acquired by the
Swift and XMM–Newton satellites in the same period. The WEBT and satellite observations
allow us to detail the synchrotron emission bump in the source spectral energy distribution
(SED). In the optical, we found a general bluer-when-brighter trend. The X-ray spectrum
remained stable during 2013, but a comparison with previous observations suggests that it be-
comes harder when the X-ray flux increases. The long XMM–Newton exposure reveals a curved
X-ray spectrum. In the SED, the XMM–Newton data show a hard near-UV spectrum, while
Swift data display a softer shape that is confirmed by previous Hubble Space Telescope/Cosmic
Origins Spectrograph and International Ultraviolet Explorer observations. Polynomial fits to
the optical–X-ray SED show that the synchrotron peak likely lies in the 4–30 eV energy range,
with a general shift towards higher frequencies for increasing X-ray brightness. However, the
UV and X-ray spectra do not connect smoothly. Possible interpretations include: (i) orienta-
tion effects, (ii) additional absorption, (iii) multiple emission components, and (iv) a peculiar
energy distribution of relativistic electrons. We discuss the first possibility in terms of an
inhomogeneous helical jet model.

It has been stated that the substitution at the phenyl cycles of the porphyrin had no significant influence on the anionic selectivity of the membrane, whereas the introduction of the axial nitrogen-containing ligand reduced the membrane specificity, the selectivity series approaching the classical Hofmeister series. All the studied electrodes have exhibited the enhanced (as compared to the Hofmeister series) selectivity towards nitrite, hydrocarbonate, and hydrophosphate anions.

dc.description.abstract

value: Cu3(SeO4)2(SeO3OH)2(H2O)16 (1) is a novel copper selenate hydrate and the first inorganic compound to contain linear octahedral–tetrahedral heptamers. The heptamers are formed by successive polymerization of two SeO3OH tetrahedra, two SeO4 tetrahedra, and three Cu(H2O)4O2 octahedra. The linkages between the octahedra and tetrahedra are in the trans-configuration, which is in agreement with the Jahn–Teller distortion of the octahedral coordination geometry of Cu2+.

dc.description.abstract

value: An extended version of the multi-pomeron exchange model for the description of pp-collisions in a wide energy range (from ISR to LHC) is presented by accounting of strange particle yields. This model effectively includes the interaction of the quark-gluon strings in the form of fusion. Differentiation of yields of various particle types is carried out in accordance with the Schwinger mechanism of string hadronization. The results on the multiplicity of strange particles, their transverse momentum and correlations are presented. A comparison with experimental data is performed. The possible influence of higher resonances on the observables, as well as the applicability of the Schwinger mechanism is discussed.

The comparative analysis of magnetic behavior of manganese-containing solid solutions
Bi3Nb1 xMnxO7 δ (x¼0.01 0.10) of cubic and tetragonal modifications was performed. Based on the
results of magnetic susceptibility studies paramagnetic manganese atoms in solid solutions of cubic and
tetragonal modifications were found to be in the form of Mn(III), Mn(IV) monomers and exchangecoupled dimers of Mn(III)–O–Mn(III), Mn(IV)–O–Mn(IV), Mn(III)–O–Mn(IV). The exchange parameters
and the distribution of monomers and dimers in solid solutions as a function of the content of paramagnetic atoms were calculated.

dc.description.abstract

value:
The main goal of this paper is to prove the following: for a triangulated
category $ \underline{C}$ and $E\subset \operatorname{Obj} \underline{C}$ there
exists a cohomological functor $F$ (with values in some abelian category) such
that $E$ is its set of zeros if (and only if) $E$ is closed with respect to
retracts and extensions (so, we obtain a certain Nullstellensatz for functors
of this type). Moreover, for $ \underline{C}$ being an $R$-linear category
(where $R$ is a commutative ring) this is also equivalent to the existence of
an $R$-linear $F: \underline{C}^{op}\to R-\operatorname{mod}$ satisfying this
property.
  As a corollary, we prove that an object $Y$ belongs to the corresponding
"envelope" of some $D\subset \operatorname{Obj} \underline{C}$ whenever the
same is true for the images of $Y$ and $D$ in all the categories $
\underline{C}_p$ obtained from $ \underline{C}$ by means of "localizing the
coefficients" at maximal ideals $p\triangleleft R$. Moreover, to prove our
theorem we develop certain new methods for relating triangulated categories to
their (non-full) countable triangulated subcategories.
  The results of this paper can be applied to the study of weight structures
and of triangulated categories of motives.

dc.description.abstract

value: Electronic tongue technology based on arrays of cross-sensitive chemical sensors and chemometric data processing has attracted a lot of researchers' attention through the last years. Several so far reported applications dealing with pharmaceutical related tasks employed different e-tongue systems to address different objectives. In this situation, it is hard to judge on the benefits and drawbacks of particular e-tongue implementations for R&D in pharmaceutics. The objective of this study was to compare the performance of six different e-tongues applied to the same set of pharmaceutical samples. For this purpose, two commercially available systems (from Insent and AlphaMOS) and four laboratory prototype systems (two potentiometric systems from Warsaw operating in flow and static modes, one potentiometric system from St. Petersburg, one voltammetric system from Barcelona) were employed. The sample set addressed in the study comprised nine different formulations based on caffeine citrate, lactose monohydrate, maltodextrine, saccharin sodium and citric acid in various combinations. To provide for the fair and unbiased comparison, samples were evaluated under blind conditions and data processing from all the systems was performed in a uniform way. Different mathematical methods were applied to judge on similarity of the e-tongues response from the samples. These were principal component analysis (PCA), RV' matrix correlation coefficients and Tuckeŕs congruency coefficients.

value: The article is a brief presentation of the voluminous book by the Moscow archivist and historian of architecture Mariia V. Nikolaeva Sankt-Peterburg of Peter I: The History of Household Possession -Site Development, Owners and Builders, released in Russian by the Progress-Tradition Publ. in 2014. It is a successful combination of scientific research and publication of archival documents (from the RGADA funds) clearly seen in the book structure. Comprehensive introductory part, in addition to the “Foreword”, includes chapters “The Sources Survey”, “The Archeographic Entry” and “An Essay on the History of Private Construction in St. Petersburg of Petrine time”. The first part of the monograph contains a detailed analysis of house possession on the Vasilieskii isle and along the Neva embankments of Admiralteiskii and Gorodskoi islands and Moskovskaia district. In the second part Nikolaeva lists the contract registers and cites their text. A lot of black-and-white reproductions of plans and drawings of the first half of the 18th century is an essential part of the research. The vast application comprises a glossary, an index, a list of abbreviations. The relevance of the book lies not only in introducing into the scientific use and a deeply serious and compelling analysis of new documents on the history of the Petrine Petersburg architecture, but also, first and foremost, in fixing the household possession topics in modern Russian historiography and developing methods of its comprehensive studies.

Saint-Petersburg macro urban landscape is situated in the most important part of the Baltic environment.
Th is urban landscape is situated in the Neva Lowland and is known as the most anthropogenically
transformed part of Russian North-West and Scandinavian region. Saint-Petersburg city has a huge area
of hydraulically constructed (alluvial) soils or soil-like bodies, situated on the banks of the Gulf of Finland.
Th ese constructed grounds form the territory of parks in residential areas. Soils of the alluvial territories,
created by human, play an important role in landscapes functioning and formation of ecological stability.
Alluvial fi lled territories are considered as a semi-natural environmental model of landscape development
in urban conditions. New formed soils of artifi cial landscapes have been described and their ecological
functions are discussed as well. Constructed ground is characterized by problematic physical properties,
which are not favourable for plants, soils of new formed plots show evidences of increased hyrdomorphism,
gleyfi cation and formation of contrast layers phenomena. Artifi cial grounds of new hydraulically formed
lands are characterized by number of soil-ecological problems.

dc.description.abstract

value: Карьеры по добыче медного колчедана изучены в Башкирском Зауралье как проблемные экологические объекты региона. Установлено, что при полуселективной укладке вскрышных пород на поверхности отвалов нередко оказываются токсичные грунты – токсилитостраты, неблагоприятность которых связана во многом с сильнокиcлой реакцией среды вследствие выветривания серосодержащих минералов. Рекультивация отвалов частично снимает эту проблему. Тем не менее почвообразование на отвалах почти не выражено, проявляется местами в формировании слаборазвитых гумусовых горизонтов небольшой мощности. Биологическая активность почвы низка, что связано с неразвитостью микробного сообщества, это касается даже рекультивированных почв. Содержание тяжелых металлов (подвижных и валовых форм) не превышает уровни ПДК, принятые в РФ. Это связано с низкой аккумулятивной и сорбционной способностью новообразованных почв.

value:
The main goal of this paper is to define a certain {\it Chow weight
structure} $w_{\operatorname{Chow}}$ on the category
$\mathcal{DM}_c(S)$ of (constructible) $cdh$-motives over an equicharacteristic
scheme $S$. In contrast to the
previous papers of D.~H\'ebert and the first author on weights for
relative motives (with rational coefficients), we can achieve our goal for motives
with integral coefficients (if $\operatorname{char} S=0$; if $\operatorname{char} S=p>0$ then we
consider motives with ${\mathbb{Z}}[\frac{1}{p}]$-coefficients). We prove that the
properties of the Chow weight structures that were previously
established for ${\mathbb{Q}}$-linear motives can be carried over to this "integral"
context (and we generalize some of them using certain new methods). In this paper we mostly study
the version of $w_{\operatorname{Chow}}$ defined via "gluing from strata"; this enables
us to define  Chow weight structures for a wide class of base schemes.

As a consequence, we certainly obtain certain (Chow)-weight spectral
sequences and filtrations on any (co)homology of motives.

dc.description.abstract

value: The paper presents the technique for computing current–time characteristics of the transient regime, taking place after the pulsed application or change of high voltage, and dynamical current–voltage ones obtained with the voltage sawtooth modulation. The basis of the simulation is the complete set of electrohydrodynamic equations with both the convective and the migration mechanisms of charge transport being taken into account jointly. The numerical calculations were performed using commercial software package COMSOL Multiphysics based on the finite element method. The simulation was carried out for the needle–plane electrode system. The unsteady-state current passage processes, including electrohydrodynamic flow formation, were calculated. The interrelation between the latter and the total current passing through the electrical circuit were investigated. The shape and features of the current–voltage characteristics obtained with the voltage sawtooth modulation were shown to be dependent on the mechanism of charge formation. The qualitative comparison between the simulated dynamical current–voltage characteristics and the original experimental data has shown a good agreement.

value: Photochemical properties of regioregular poly(3-hexylthiophene) (P3HT), fullerene derivative [6,6]phenyl C61-butyric acid methyl ester (PC60BM) and their 1:1 mixture in argon-saturated toluene solution were studied by optical spectroscopy and nanosecond laser flash photolysis (lambda(ex) = 532 nm). Separate excitation of components leads to formation of corresponding triplet state of fullerene ((PC60BM)-P-3*, lambda(max) = 710 nm, epsilon(max) = 22400 M-1 cm(-1), phi(T) = 0.29) and polymer ((3)P3HT*, lambda(max) = 850 nm, epsilon(750 nm) <= 10(5) M-1 cm(-1), phi(T) >= 0.19). Excitation of P3HT/PC60BM mixture leads to effective energy transfer from (3)P3HT* to the ground state of fullerene with a formation of (PC60BM)-P-3*. No evidence of ion-radical P3HT(+center dot) and PC60BM-center dot formation was obtained though electron transfer between (3)P3HT* and (PC60BM)-P-1 is energetically favorable in studied system. Presumably ultrafast back electron transfer takes place in geminate P3HT(+center dot)/PC60BM-center dot pair with regeneration of the ground states of P3HT and PC60BM. (C) 2015 Elsevier B.V.

dc.description.abstract

value: In clinical analysis creatinine is a routine biomarker for the assessment of renal and muscular dysfunctions. Although several techniques have been proposed for a fast and accurate quantification of creatinine in human serum or urine, most of them require expensive or complex apparatus, advanced sample preparation or skilled operators. To circumvent these issues, we propose two home-made platforms based on a CD Spectroscope (CDS) and Computer Screen Photo-assisted Technique (CSPT) for the rapid assessment of creatinine level in human urine. Both systems display a linear range (r(2) = 0.9967 and 0.9972, respectively) from 160 μmol L(-1) to 1.6 mmol L(-1) for standard creatinine solutions (n = 15) with respective detection limits of 89 μmol L(-1) and 111 μmol L(-1). Good repeatability was observed for intra-day (1.7-2.9%) and inter-day (3.6-6.5%) measurements evaluated on three consecutive days. The performance of CDS and CSPT was also validated in real human urine samples (n = 26) using capillary electrophoresis data as reference. Corresponding Partial Least-Squares (PLS) regression models provided for mean relative errors below 10% in creatinine quantification.

value:
Upper-mantle xenoliths in Cenozoic basalts of northwestern Spitsbergen are rocks of peridotite (spinel lherzolites) and pyroxenite
(amphibole-containing garnet and garnet-free clinopyroxenites, garnet clinopyroxenites, and garnet and garnet-free websterites) series. The
upper-mantle section in the depth range 50–100 km is composed of spinel peridotites; at depths of 80–100 km pyroxenites (probably, dikes
or sills) appear. The equilibrium conditions of parageneses are as follows: in the peridotites—730–1180 ºC, 13–27 kbar, and oxygen fugacity
of –1.5 to +0.3 log. un.; in the pyroxenites—1100–1310 ºC, 22–33 kbar. The pyroxenite minerals have been found to contain exsolved
structures, such as orthopyroxene lamellae in clinopyroxene and, vice versa, clinopyroxene lamella in orthopyroxene. The formation
temperatures of unexsolved phases in orthopyroxene and clinopyroxene are nearly 100–150 ºC higher than the temperatures of the
lamellae–matrix equilibrium and the equilibrium of minerals in the rock. The normal distribution of cations in the spinel structure and the
equilibrium distribution of Fe2+ between the M1 and M2 sublattices in the orthopyroxenes point to the high rate of xenolith ascent from the
rock crystallization zone to the surface. All studied Spitsbergen rock-forming minerals from mantle xenoliths contain volatiles in their structure:
OH–, crystal hydrate water H2Ocryst, and molecules with characteristic CH and CO groups. The first two components are predominant, and
the total content of water (OH- + H2Ocryst) increases in the series olivine → garnet → orthopyroxene → clinopyroxene. The presence of
these volatiles in the nominally anhydrous minerals (NAM) crystallized at high temperatures and pressures in the peridotites and pyroxenites
testifies to the high strength of the volatile–mineral bond. The possibility of preservation of volatiles is confirmed by the results of comprehensive
thermal and mass-spectral analyses of olivines and clinopyroxene, whose structures retain these components up to 1300 ºC. The composition
of hypothetic C–O–H fluid in equilibrium (in the presence of free carbon) with the underlying mantle rocks varies from aqueous (>80% H2O)
to aqueous–carbonic (~60% H2O). The fluid becomes essentially aqueous when the oxygen activity in the system decreases. However, there
is no strict dependence of the redox conditions on the depth of formation of xenoliths.

dc.description.abstract

value: The measurement of the mass differences for systems bound by the strong force has reached a very high precision with protons and anti-protons1, 2. The extension of such measurement from (anti-)baryons to (anti-)nuclei allows one to probe any difference in the interactions between nucleons and anti-nucleons encoded in the (anti-)nuclei masses. This force is a remnant of the underlying strong interaction among quarks and gluons and can be described by effective theories3, but cannot yet be directly derived from quantum chromodynamics. Here we report a measurement of the difference between the ratios of the mass and charge of deuterons (d) and anti-deuterons ( ), and 3He and nuclei carried out with the ALICE (A Large Ion Collider Experiment)4 detector in Pb–Pb collisions at a centre-of-mass energy per nucleon pair of 2.76 TeV. Our direct measurement of the mass-over-charge differences confirms CPT invariance to an unprecedented precision in the sector of light nuclei5, 6. This fundamental symmetry of nature, which exchanges particles with anti-particles, implies that all physics laws are the same under the simultaneous reversal of charge(s) (charge conjugation C), reflection of spatial coordinates (parity transformation P) and time inversion (T).

dc.description.abstract

value: This paper studies a class of systems with discontinuous right-hand side, which is commonly used in various applications. The notion of discontinuous system is closely linked to the notion of differential inclusion, which was first considered by Marchaud and Zaremba. In this paper three different notions of solutions of differential equations will be considered: Filippov, Aizerman-Pyatnitskiy and Gelig-Leonov-Yakubovich solutions. For the class of systems considered in the paper it is discussed when these definitions coincide and when they differ. The application of definitions is also demonstrated by numerical modelling of hidden attractor in Chua's circuit.

dc.description.abstract

value: Recently the question on drilling rigs failures due to hidden oscillations was actively discussed. For instance, it was shown by the scientific group from Eindhoven University of Technology that such oscillations may appear in drilling rigs actuated by DC motor. In the works of the authors same effect was found for models of rigs with induction motor. Here a new mathematical model of a drilling rig activated by a salient pole synchronous motor is considered. Numerical modelling of the obtained model is performed.

dc.description.abstract

value: We have suggested a novel approach for classification of flow methods according to the conditions under which the mass transfer processes and chemical reactions take place in the flow mode: dispersion-convection flow methods (1) and forced-convection flow methods (2). The first group includes continuous flow analysis, flow injection analysis, all injection analysis, sequential injection analysis, sequential injection chromatography, cross injection analysis, multicommutated flow analysis, multisyringe flow injection analysis, multi-pumping flow systems, loop flow analysis and simultaneous injection effective mixing flow analysis. The second group includes segmented flow analysis, zone fluidics, flow batch analysis, sequential injection analysis with a mixing chamber, stepwise injection analysis and multicommutated stepwise injection analysis. The offered classification allows to systematize a large number of the flow methods. Recent development and application of dispersion-convection flow methods and forced-convection flow methods are presented. [Figure: see text].

value: В диссертации предложена логико-когнитивная формализованная теория аргументации, предназначенная для моделирования трех видов аргументации – обоснования, убеждения и практической аргументации при помощи абстрактных аргументационных структур. Аргументация – это интеллектуальная познавательная деятельность, в ходе которой участники спора изучают, насколько выдвигаемые ими позиции состоятельны, т.е. способны противостоять критике, что формально представлено как определенный способ упорядочивания выражающего ее аргументационного множества на аргументационной структуре данного спора. Объектом аргументации выступает когнитивный агент – участник спора в аспекте своих знаний, убеждений, целей и намерений, составляющих его позицию в споре. Формальная часть теории включает три формализма - минимальную, стандартную и относительную аргументационные системы и проиллюстрирована на примерах известных споров: Кухонного спора Н.Хрущева и Р.Никсона и спора Протагора и Эватла. В  диссертации дается классификация современных подходов к анализу аргументации.

dc.description.abstract

value: The reaction of [Cu(NCMe)4][PF6] with aromatic acetylenes HC2R and triphosphine 1,1,1-tris(diphenylphosphino)methane in the presence of NEt3 results in the formation of hexanuclear Cu(I) clusters with the general formula [Cu6(C2R)4{(PPh2)3CH}2][PF6]2 (R = 4-X-C6H4 (1-5) and C5H4N (6); X = NMe2 (1), OMe (2), H (3), Ph (4), CF3 (5)). The structural motif of the complexes studied consists of a Cu6 metal core supported by two phosphine ligands and stabilized by σ- and π-coordination of the alkynyl fragments (together with coordination of pyridine nitrogen atoms in cluster 6). The solid state structures of complexes 2-6 were determined by single crystal XRD analysis. The structures of the complexes in solution were elucidated by (1)H, (31)P, (1)H-(1)H COSY NMR spectroscopy, and ESI mass spectrometry. Clusters 1-6 exhibit moderately strong phosphorescence in the solid state with quantum yields up to 17%. Complexes 1-5 were found to form solvates (acetone, acetonitrile) in the solid state. The coordination of loosely bound solvent molecules strongly affects emission characteristics and leads to solvato- and vapochromic behavior of the clusters. Thus, solvent-free and acetonitrile solvated forms of 3 demonstrate contrasting emission in orange (615 nm) and blue (475 nm) regions, respectively. The computational studies show that alkynyl-centered IL transitions mixed with those of MLCT between the Cu6 metal core and the ligand environment play a dominant role in the formation of excited states and can be considerably modulated by weakly coordinating solvent molecules leading to luminescence vapochromism.

value: Bondarenko, Anton

dc.description.abstract

value: Using scanning electron microscopy in the cathodoluminescence mode, it is shown that straight segments of a-screw dislocations introduced by plastic deformation at room temperature into unintentionally doped low-resistance gallium nitride luminesce in the spectral range 3.1–3.2 eV at 70 K. The spectral composition of dislocation luminescence shows a fine doublet structure with a component width of ∼15 meV and splitting of ∼30 meV, accompanied by LO-phonon replicas. Luminescent screw dislocations move upon exposure to an electron beam and at low temperatures, but retain immobility for a long time without external excitation. Optical transitions involving the quantum-well states of a stacking fault in a split-dislocation core are considered to be the most probable mechanism of the observed phenomenon.

title: New Facts about James Walker in Russia

dc.description.abstract

value:
The English mezzotint engraver James Walker (c. 1760 – c. 1823), a pupil of the famous Valentine Green,  was invited to Russia by Empress Catherine the Great and spent nearly twenty years at  her court, from 1784 to 1802. A number of English engravers – most of them mediocre – emigrated because of the fierce competition in Britain and the demand for their art on the Continent. Walker, however, was a notable exeption: one of the most eminent masters of mezzotint, he chose to link his destiny with Russia.
The present article reports some new facts about Walker’s print production and life, gleaned from two unpublished mnuscripts on Russian-English artistic links compiled by Alexandra Müller in the 1920s or 1930s, preserved in the Department of Manuscripts of the Russian national library, St Petersburg, and from entries in a contemporary Russian newspaper. An updated version of Anthony Cross’s 1993 list of Walker’s plates made in Russia is provided in the Appendix.

Англию обычно покидали посредственные мастера: не способные выдержать конкуренцию на родине, они искали себе применение на континенте, где меццотинто было весьма востребовано.

dc.description.abstract

value:
Humic acids (HAs) and fulvic acids (FAs) of two Polar soils were investigated by 13C NMR and ESR spectroscopies, investigating
the degree of humification and the molecular structure. One soil, from Bolshoi Lyakhovsky Island, contains two humus horizons:
modern and buried. The other soil, fromWrangel Island, had only one modern humus horizon.The HAs and FAs of the two soils
investigated show essential differences.The HAs show fewer oxygen-containing groups in comparison with the FAs, whereas the
degree of aromaticity is two or three times higher in the HAs. The 13C NMR data also show that HAs are very different from FAs in
terms of their molecular composition and hydrophobicity. Humification in the Arctic is limited by the very low content of ligninderived
compounds, due to the restricted vascular flora. As a result, the HAs, isolated from Polar soils, are more similar to the
corresponding FAs than to the typical HAs of temperate soils. This was confirmed by ESR data, which show similar levels of free
radical concentration for HAs and FAs and are related to the low level of aromaticity of both materials investigated. Apparently, the
humification process in the soils of Polar Arctic deserts is in an initial stage.

dc.description.abstract

value: We consider gravity interacting with matter scalar fields and quantized in the superspace approach in which the wave functional is described by the Wheeler–DeWitt equations. Assuming the dominance of the homogeneous and isotropic geometry, we investigate the leading contribution to the wave functional in the minisuperspace approximation with the Friedmann–Robertson–Walker metric and scalar fields depending on the time parameter. We construct a model of several scalar fields with exponential potentials and kinetic terms admitting a special mixing such that it is ultimately possible to separate the variables in the Wheeler–DeWitt equation and find its exact solution in terms of special functions. We study the semiclassical approximation in detail and choose boundary conditions that allow selecting the physical solution for classical cosmologies.

dc.description.abstract

value: Настоящее пособие ставит своей целью привлечение пристального внимания студентов к важности корректного перевода в сложившихся на сегодня условиях информационных войн. Одной из основных трудностей для переводчика является проблема адекватного перевода субъективного содержания различных текстов. Для этого недостаточно знать значения отдельных языковых единиц, необходимо также суметь распознать все те связи, в которых они существуют в тексте (в нашем случае, в прессе и информационном пространстве интернета).  Именно эти текстовые связи расширяют (трансформируют и переосмысляют) исходное значение слов. Задачей курса общественно-политического перевода является овладение и закрепление навыков последовательного и синхронного перевода самых разнообразных по жанру текстов общественно-значимой тематики.

dc.description.abstract

value: Вторая часть учебного пособия по аналитическому чтению для II курса румынского отделения содержит адаптированные тексты, представляющие народную прозу (сказки).   Языковые материалы снабжены разного рода комментариями и справочными сведениями. Акцент делается не просто на запоминании и воспроизведении исходного текста, а на развитии у студента способности квалифицировать прочитанное с точки зрения стилистики текста, его жанровой принадлежности. Целью является формирование навыков не только лингвистического, но и литературоведческого анализа на румынском языке (в приложении даются соответствующие термины). Контрольные задания на итоговых обсуждениях с привлечением широкого спектра информации по культуре Румынии помогут закрепить полученные умения и научат самостоятельно рассуждать при выполнении переводов текстов художественной литературы в дальнейшей профессиональной деятельности.

Tam, editors, Proceedings of the British Machine Vision Conference (BMVC), pages 162.1-162.12. BMVA Press, September 2015.

dc.description.abstract

value: We propose a new method for camera pose estimation with unknown focal length (PnPf problem). We combine projection equations and distance constraints in a single statistically significant cost function in the form of least squares. We fix the space of the search as a linear combination of several right singular vectors of the least squares system matrix. We use linear programming techniques to find feasible solutions faster. Then we do nonlinear refinement with Levenberg-Marquardt. Numerical experiments demonstrated that the method is faster than the state-of-the-art methods for point numbers up to several hundreds, and real-life structure-from-motion demonstrates its applicability for models having $10^3$-$10^5$ points. It has the same accuracy of estimates as the the state-of-the-art methods. We show that the method offers a tradeoff between speed and accuracy, allowing the estimation to run several times faster while slightly increasing the mean reprojection error.


title: A gas-diffusion flow injection method coupled with online solid-liquid extraction for the determination of ammonium in solid samples

dc.description.abstract

value: A simple, rapid and reliable gas-diffusion flow injection (GD-FI) method for ammonium determination in building materials has been developed. It is based on leaching ammonium from a ground solid sample into an alkaline solution with subsequent ammonia gas generation. Ammonia is then transported in a nitrogen stream to the GD cell of the FI system where it is absorbed into its acceptor solution containing a mixture of the acid-base indicators cresol red and thymol blue. The maximum increase in the absorbance of the acceptor solution at 580 nm is related to the ammonium concentration in the solid sample. The proposed method is characterized by a linear concentration range of 0.1-5.0 mg NH4(+) kg(-1), a limit of detection of 8 μg NH4(+) kg(-1) and a sample throughput of 10h(-1). A successful application of this method for the determination of ammonium in building materials such as concrete, cement and sand is reported.

value: Single crystals of seven novel uranyl oxysalts of selenium with protonated methylamine molecules, [C2H8N]2[(UO2)(SeO4)2(H2O)] (I), [C2H8N]2[(UO2)2(SeO4)3(H2O)] (II), [C4H15N3][H3O]0.5[(UO2)2(SeO4)2.93(SeO3)0.07(H2O)](NO3)0.5 (III), [C2H8N]3[H5O2][(UO2)2(SeO4)3(H2O)2]2(H2O)5 (IV), [C2H8N]2[H3O][(UO2)3(SeO4)4(HSeO3)(H2O)](H2SeO3)0.2 (V), [C4H12N]3[H3O][(UO2)3(SeO4)5(H2O)] (VI), and [C2H8N]3(C2H7N)[(UO2)3(SeO4)4(HSeO3)(H2O)] (VII) have been prepared by isothermal evaporation from aqueous solutions. Their crystal structures have been solved by direct methods and their uranyl selenate and selenite–selenate units investigated using black-and-white graphs from the viewpoints of topology of interpolyhedral linkages and isomeric variations. The crystal structure of IV is based upon complex layers with unique topology, which has not been observed previously in uranyl selenates. Investigations of the statistics and local distribution of the U–Obr–Se bond angles demonstrates that shorter angles associate with undulations, whereas larger angles correspond to planar areas of the uranyl selenite layers.

value: Thiourea  derivatives  have  been  actively  used  in  technology    of    rare    and    scattered    elements,    for    example,  as  the  specific  ligands  for  isolation  of  the  platinum    group    metals    from    the    solutions    of  radioactive  wastes.  The  compounds  are  interesting  in  view  of  investigation  of  the  processes  leading  to  in vivo  inactivation  of  cytostatic  drugs  in  the  course  of  therapy of oncological diseases. Herein we report on synthesis and X-ray diffraction analysis of new mononuclear complex of palladium(II) with     (4-thioxo-2,3,5,6-tetrahydro-1,3,5-triazin-1-yl)-acetic  acid  (HL).

title: Интерпретация спектров ЯМР на ядрах 1H, сборник упражнений

dc.contributor.author

value: Толстой, П.М.

dc.description.abstract

value: Настоящий сборник упражнений является учебным пособием к курсу «Магнитный резонанс» и предназначен студентов, начинающих знакомство с ЯМР как с методом определения структуры органических соединений. Материалом для упражнений служат оригинальные экспериментальные данные, полученные на спектрометре ЯМР с рабочей частотой 60 МГц для ядер 1H. Для спектроскопии ЯМР данная частота не является современной, ее можно даже назвать архаичной (современные спектрометры высокого разрешения работают на частотах 400-1000 МГц). Однако, существенным преимуществом, определившим выбор частоты, является наглядность: в этом случае константы спин-спинового взаимодействия отчетливее видны на спектрах (реже требуется делать «врезки» для отдельных линий, чтобы показать расщепление), ярче проявляются эффекты взаимодействия мультиплетов («эффект крыши»), студенты лучше усваивают связь шкал химических сдвигов и частот. Знания и навыки, полученные при решении предложенных в сборнике упражнений, с легкостью переносятся на спектры, зарегистрированные на других приборах.

value: The lattice model for a star-shaped polymer with a total number of up to 72 segments is considered. The number of arms varied, ranging from 2 to 6. Entropic sampling Monte Carlo simulation is used to obtain the equilibrium, thermal and structural properties of the considered systems over a wide range of temperatures. The coil-globule transition is observed and the transition temperature is shown to shift toward lower temperatures with an increase in the number of arms. This study demonstrates how the structure of the star-shaped polymer affects its equilibrium properties.
