value:
The goal of this paper is to prove: if certain 'standard' conjectures on
motives over algebraically closed fields hold, then over any 'reasonable' $S$
there exists a motivic $t$-structure for the category of Voevodsky's
$S$-motives (as constructed by Cisinski and Deglise). If $S$ is 'very
reasonable' (for example, of finite type over a field) then the heart of this
$t$-structure (the category of mixed motivic sheaves over $S$) is endowed with
a weight filtration with semi-simple factors. We also prove a certain 'motivic
decomposition theorem' (assuming the conjectures mentioned) and characterize
semi-simple motivic sheaves over $S$ in terms of those over its residue fields.
Our main tool is the theory of weight structures. We actually prove somewhat
more than the existence of a weight filtration for mixed motivic sheaves: we
prove that the motivic $t$-structure is transversal to the Chow weight
structure for $S$-motives (that was introduced previously and independently by
D. Hebert and the author; weight structures and their transversality with
t-structures were also defined by the author in recent papers). We also deduce
several properties of mixed motivic sheaves from this fact. Our reasoning
relies on the degeneration of Chow-weight spectral sequences for 'perverse
'etale homology' (that we prove unconditionally); this statement also yields
the existence of the Chow-weight filtration for such (co)homology that is
strictly restricted by ('motivic') morphisms.

title: Liquidity, cash conversion cycle and financial performance: case of Russian companies

dc.description.abstract

value: Managing liquidity and the cash conversion cycle play an important role in running a business successfully. Company officials must be confident that their organization does not suffer a shortage or a surplus of payment means and they must be ready to cover current liabilities when necessary. At the same time, the management’s aim is an increase in the company’s returns. The research covers the influence of the current liquidity ratio and cash conversion cycle on financial performance (as a return on net operating assets, RNOA) of Russian companies. A regression analysis of 720 Russian companies engaged in various economic activities for the period 2001 to 2012 was performed with Stata 12.0. The companies in the sample represent the following industries: telecommunications, transport, electric power industry, trade, metallurgy, mechanical engineering, chemical and petrochemical, oil and gas. The authors find an inverse relation between the Russian companies’ cash conversion cycle and RNOA. Further research revealed that companies should seek to obtain a zero cash conversion cycle in order to increase their rate of return. The study also indicated a positive relation between companies’ current liquidity ratio and RNOA. This means that Russian companies should augment their current liquidity ratio in order to increase the RNOA, but the ratio should only be augmented to a defined value. In the paper we also present the calculations of the recommended intervals of current ratio for the analyzed economic sectors for the contemporary economic situation in Russia.

Despite the fact that there are thousands of programming
languages existing there is a huge controversy about what language is
better to solve a particular problem. In this paper we discuss requirements
for programming language with respect to AGI research. In this article
new language will be presented. Unconventional features (e.g. probabilistic
programming and partial evaluation) are discussed as important
parts of language design and implementation. Besides, we consider possible
applications to particular problems related to AGI. Language interpreter
for Lisp-like probabilistic mixed paradigm programming language
is implemented in Haskell.

dc.description.abstract

value:
Management sociology poses the problem of the quantita
tive interpretation of qualitative research. The article
deals with the corpus-based method, which can be considered as one of the solution tools. Based on ‘grounded
theory’ methodology (Strauss & Corbin, n. d.) and partly de
bating with conceptual analysis (Sartory & Goertz, n.
d.), we propose to elaborate a definition of the concep
t using quantitative research. The authors identified useful
areas of corpus linguistics in the analysis of social and management phenomena and distinguished between
corpus linguistics and sociologi
cal content analysis methods:
- Direct appeal to the everyday use of the lan
guage increases the objec
tivity of the research;
- A corpus provides a large quantity of representative data;
- The possibility of diachronic and synchronic comparative studies;
- The method itself is not time-consuming and expensive.
We chose the category ‘altruism’ as an example to de
monstrate the possibilities of the method. The analysis
shows features in the representation of altruism in Russian that the field of management sociology needs to
address for the prepara
tion of questionnaires, interview guides and transcript analysis

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: Finnish National Certiﬁ cates of Language Proﬁ ciency examination is intended for adults and  assesses language skills in practical situations where adults may generally need to speak, listen, write and read in the foreign language. It comprises three subtests at six levels: Basic (1–2 levels), Intermediate (3–4 levels) and Advanced (5–6 levels). The proﬁ ciency level scale of the Finnish National Certiﬁ cates of Language Proﬁ ciency is linked to the scale of the Common European Framework (CEFR). Finnish National Certiﬁ cates of Language Proﬁ ciency examination tests all four language skills — reading comprehension, listening comprehension, writing and speaking. Applicants for Finnish citizenship have to demonstrate the required level of proﬁciency in Finnish or Swedish. A succesful applicant is required to pass the 3d level (~ level B1) both in oral (listening and speaking) and wtitten (reading comprehension and writing) parts of the test. The article discusses the test results gained by the Russian test takers in all these parts of the test and reveals correspondence of their language skills to the requirements for acquiring Finnish citizenship. The article represents a summary of the test results and survey data conducted among the test takers in 2012 (a total number of the test takers, n = 5097) and 2013 (n = 5996). From the total number of the test takers, the number of the test takers who have Russian as a native language amounts to 30 %. Moreover, the article reveals how variable factors can inﬂ uence the test results, namely gender, education, language preparation courses and use of language in various contexts.

value: Overina, Ksenia

dc.description.abstract

value: The article discusses the problem of the narrative structure and genre transformations in early Chekhov’s stories. “Late-blooming Flowers” is known as one of the serious stories written by Chekhov in the 1880s. Nevertheless, it is written for those readers who prefer popular literature. In terms of severe competition, authors were to make up such literary devices that would allow them not only to satisfy readers’ expectations but also to surprise the audience. “Late-blooming Flowers” represents two narrative strategies: it demonstrates to the reader the fictitious nature of the stories and characters, but at the same time makes the readers identify themselves with the feelings of the characters, understand the feeling of the text.

Чехова. «Цветы запоздалые» имеют репутацию одного из серьезных текстов писателя, созданных в 1880-е гг. Тем не менее, эта повесть ориентирована на массового читателя. В условиях большой конкуренции писатели должны были находить такие литературные приемы, которые позволили бы им не только оправдать читательские ожидания, но и удивить аудиторию. В «Цветах запоздалых» сочетаются две повествовательные стратегии: читателю демонстрируется фикциональная природа произведения и персонажей, но одновременно с этим его вынуждают отождествиться с чувствами героев, вчувствоваться в текст.

value:
Why mathematics can adequately describe the physical reality? How one can rationally
explain the “unreasonable effectiveness” of mathematics in physics and other natural sciences?
In the fi
 rst part of this work we propose an answer to this question within the context of
Classical physics and mathematics. Following Hilbert we distinguish between the real and
the ideal semantics of syntactic operations in mathematics and show how the excessiveness
of mathematical syntax allows one to complement the real semantics with the ideal one. Then
on the basis of our analysis of Kepler’s astronomy we introduce the notion of realistic physical
theory and show that the “unreasonable effectiveness of mathematics” in such theories amounts
to the possibility (not granted a priori but often realized in experiments) to replace a part of the
standard ideal semantics of mathematical syntax with an appropriate real semantics

Почему с помощью математических теорий удается адекватно описывать физическую
реальность? Как рационально объяснить “непостижимую эффективность” математики в
физике и других естественных науках? В первой части данной работы предлагается ответ
на этот вопрос в контексте классической физики и математики. Вслед за Гильбертом мы
различаем реальную и идеальную семантику синтаксических операций в математике и
показываем, каким образом избыточность математического синтаксиса позволяет допол-
нить реальную семантику идеальной. Далее на основании анализа астрономии Кеплера
мы вводим понятие реалистической физической теории и показываем, что “непостижимая
эффективность математики” в такого рода теориях состоит в возможности (не гарантиро-
ванной априори, но часто реализуемой в эксперименте) частичной замены стандартной
идеальной семантики математического синтаксиса подходящей реальной семантикой

value:
In this article, the process of the emergence of Muslim communities in the Arab Vilayet (Province)
of Arminiya, which was formed in early 8th century by the way of occupation of the territories of
Christian principalities in the Armenian Highland and the Southern Caucasus, was investigated the
first time in detail on the basis of the early medieval Armenian and Georgian as well as Muslim writers.
As a result, the author concluded that the Muslim communities in Arminiya were formed due to the
mass migration of Arab tribes, as well as the islamization of the local Iranian-spoken Persians and
autochthonous Caucasus-spoken Albanians, which were not only exempted in this way from paying
a burdensome poll tax, but also could be engaged into management of the Pan-Islamic caliphate. At
the same time the Muslim communities in Arminiya were replenished due to the interpenetration of
an alien Arab and autochthonic Armenian nobility by marriage, as well as the forcible islamization of
Christian rebellious princes, which saved in this way their lives. Refs 25.

В статье на основании сведений раннесредневековых армянских, грузинских, а также му-
сульманских писателей впервые подробно изучен процесс становления мусульманской общ-
ности в арабском вилайете (провинции) Арминийа, который был образован в начале VIII в.
из территорий покоренных христианских княжеств Армянского нагорья и Южного Кавказа.
В результате автор пришел к заключению, что мусульманские общины в Арминийи форми-
ровались за счет массового переселения сюда арабских племен, а также исламизации мест-
ных ираноязычных персов и автохтонных кавказоязычных албанцев, которые таким обра-
зом освобождались и от уплаты обременительной подушной подати и могли быть вовлечены

title: Readership Problem in A. P. Chekhov's Early Parodies (Arabian Frights or a Night of Horrors, Flying Islands)

dc.contributor.author

value: Overina, Ksenia

dc.description.abstract

value: The article is dealing with the problem of the early Anton Chekhov’s parodies, their narrative structure and genre. Using literary devices from great works of Russian and Europian literature and popular Russian fiction of the end of 19th century, Chekhov transforms narrative structure of his texts, develops special kind of communication with the audience and draws readers’ attention not only to a plot, but to a process of reading itself.

dc.description.abstract

value:
In the second part of this work we consider the question of “unreasonable effectiveness”
of mathematics in the context of the 20th century and today’s science. We explain why the
revolutionary changes in mathematics and physics occurred in the beginning of the 20th century
made earlier answers to this question unsatisfactory. The main claim of this part of our work is
the following: the project of new realistic physics formulated by Einstein in his debate with Bohr
nowadays is again pertinent because of some latest developments in foundations of mathematics.
This is why the pattern of Classical realistic science where mathematics serves as an effective
means of theoretical description and experimental design (van Fraassen) remains relevant to
today’s science and may motivate new ambitious research programs.

Во второй части работы вопрос о “непостижимой эффективности” математики
рассмотрен в контексте физики и математики ХХ в. и современности. Показано, каким
образом революционные изменения в математике и физике начала ХХ в. привели к тому,
что старые ответы на этот вопрос перестали быть удовлетворительными. Основной те-
зис второй части статьи состоит в том, что программа развития новой реалистической
физики, которую Эйнштейн сформулировал в дискуссии с Бором, в настоящее время
вновь стала актуальной, в том числе в связи с некoторыми новейшими результатами в
области оснований математики. Поэтому образец классической реалистической науки,
в котором математика играет роль эффективного средства теоретического описания
и экспериментального дизайна (в смысле ван Фраассена), остается релевантным со-
временному состоянию науки и может мотивировать новые амбициозные программы
исследований

title: Efficient processing and classification of wave energy spectrum data with a distributed pipeline

dc.contributor.author

value: Ivan Gankevich

value: Alexander Degtyarev

dc.description.abstract

value: Processing of large amounts of data often consists of several steps, e.g. pre- and post-processing stages, which are executed sequentially with data written to disk after each step, however, when pre-processing stage for each task is different the more efficient way of processing data is to construct a pipeline which streams data from one stage to another. In a more general case some processing stages can be factored into several parallel subordinate stages thus forming a distributed pipeline where each stage can have multiple inputs and multiple outputs. Such processing pattern emerges in a problem of classification of wave energy spectra based on analytic approximations which can extract different wave systems and their parameters (e.g. wave system type, mean wave direction) from spectrum. Distributed pipeline approach achieves good performance compared to conventional “sequential-stage” processing.

dc.description.abstract

value: Two blue mussel lineages of Pliocene origin, Mytilus edulis (ME) and M. trossulus (MT), co-occur and hybridize in several regions on the shores of the North Atlantic. The two species were distinguished from each other by molecular methods in the 1980s, and a bulk of comparative data on them has been accumulated since that times. However, while ME and MT are now routinely distinguished by various genetic markers, they tend to be overlooked in ecological studies since morphological characters for taxonomic identification have been lacking, and no consistent habitat differences between lineages have been reported. Surveying a recently discovered area of ME and MT co-occurrence in the White Sea and employing a set of allozyme markers for identification, we address the issue whether ME and MT are true biological species with distinct ecological characteristics or just virtual genetic entities with no matching morphological and ecological identities. We find that: (1) in the White Sea, the occurrence of MT is largely concentrated in harbors, in line with observations from other subarctic regions of Europe; (2) mixed populations of ME and MT are always dominated by purebred individuals, animals classified as hybrids constituting only ca. 18%; (3) in terms of shell morphology, 80% of MT bear a distinct uninterrupted dark prismatic strip under the ligament while 97% of ME lack this character; (4) at sites of sympatry MT is more common on algal substrates while ME mostly lives directly on the bottom. This segregation by the substrate may contribute to maintaining reproductive isolation and decreasing competition between taxa. We conclude that while ME and MT are not fully reproductively isolated, they do represent clearly distinguishable biological, ecological and morphological entities in the White Sea. It remains to be documented whether the observed differences are of a local character, or whether the basic morphological and ecological differences just have been so far overlooked in other contact zones.

dc.description.abstract

value: The article is focused on the problem of the relations between art of Classical antiquity and that of Byzantium. On the one hand, it is evident that the latter is the successor to the former. On the other hand, it is clear that the latter is quite different, sometimes opposite to the former. Throughout the 20th century scholars dealt with this issue differently. The authors of this article align with the approach that considers the Byzantine millennium as the continuation of Classical tradition spiritually enriched by Christianity. This study shows how some Classical architectural and iconographic models were preserved and gradually transformed into a new artistic system that was able to adequately embody new religious contents.

Изучена зависимость пространственного распространения щучки антарктической
(Deschampsia antarctica) от гнездования двух видов птиц: доминиканской чайки (Larus
dominicanus) и южнополярного поморника (Catharacta maccormicki) в течение сезона 2013/14 гг.
на примере локалитетов о-ва Галиндез (Аргентинские острова, Прибрежная Антарктика). Уста-
новлено, что пространственное распределение щучки антарктической тесно связано с места-
ми гнездования и питания доминиканской чайки. Другими благоприятными для колонизации
щучкой локалитетами острова оказались места случайной потери жизнеспособного материала
чайкой при его транспортировке. В то же время, южнополярный поморник может играть опре-
деленную роль как вторичный переносчик щучки из прибрежной зоны первичной колониза-
ции в глубь острова. Связь распределения D. antarctica с гнездовыми участками на острове под-
тверждается также данными анализов почвенных проб. Вместе с тем наблюдается определенное
антропогенное влияние на пространственное распространение щучки. При осуществлении
дальнейших исследований необходимо установить, насколько обобщения сделанные на приме-
ре о-ва Галиндез, применимы к другим районам Прибрежной Антарктики.

dc.description.abstract

value:
Features of the breakdown of the air gap with a large diameter solid dielectric barrier with pulse
voltage supply are considered. Usually the preliminary closure of the gap by streamers is necessary for the
breakdown of gaps with a length of 5–500 cm; however, in the considered systems the closure is hampered by
the large length of the path in air by passing the barrier. The results of this study make it possible to assume
that at a large diameter of the barrier the streamer–leader transition occurs on both sides of the barrier, then
the pair of leaders propagates along the barrier on its different sides to the closure at the edge of the barrier.
The possibility of the streamer–leader transition at moderate voltages (50–400 kV) can be provided by the
considerable charge value transferred through the streamer channels on the surface of the dielectric barrier.
The accumulation of the considerable charge on the surface of the barrier is possible due to the formation of
a pair of spots of the heteropolar surface charge, a kind of an electric capacity.

Complexes 21–48 demonstrated excellent activity as catalysts in copper-free Sonogashira coupling of aryl iodides and a variety of aromatic terminal alkynes. Catalytic system runs in environmentally benign EtOH ensuring product yields of up to 75–96% and TONs of up to 104. Mechanism of the copper-free Sonogashira catalytic cycle involving 21–48 as catalysts was proposed upon identification of key intermediates using HRESI-mass.

value: Layered HLnTiO4 (Ln=La, Nd) compounds belonging to Ruddlesden–Popper phases were found to form partially hydrated compounds Ln2Ti2O7·xH2O during thermal dehydration as well as defect oxides Ln2□Ti2O7 as final products. Further heating of metastable defect Ln2□Ti2O7 substances leads to the formation of pyrochlore-type oxides Ln2Ti2O7 (p), with subsequent transformation under higher temperatures to stable layered 110-type perovskites Ln2Ti2O7. The occurring structure transformations lead to an increase of photocatalytic activity in the order of HLnTiO4<Ln2Ti2O7·yH2O<Ln2□Ti2O7<Ln2Ti2O7 (p)<Ln2Ti2O7 in the reaction of hydrogen evolution from aqueous isopropanol solution.

dc.description.abstract

value:
Features of the simulation of low velocity inviscid and viscous compressible gas flows are
considered, and a finite volume discretization of gas dynamics equations at low Mach numbers on
unstructured meshes is discussed. Preconditioning based on the use of physical variables is used to
speed up the convergence of time marching to a steady state and to improve the accuracy of the steady
state solution. The structure of the preconditioning matrix and the diagonalization of the Jacobian of
the preconditioned system of equations are discussed. The capabilities of this approach are demonstrated using model gasdynamic simulations in a wide range of Mach numbers.

value: Changes in the stress-strain state of the cornea and in the intraocular pressure (IOP) readings obtained by Goldmann (GAT) and Maklakov (MAT) applanation tonometers after hyperopia correction surgery are discussed. Two types of refractive correction procedures (LASIK and IntraLASIK) are considered. In the ANSYS software package the corneasclera elastic system is presented as two conjugate transversely isotropic spherical segments loaded with internal pressure. The cornea is simulated as a multi-layered transversely isotropic elastic shell and the sclera is modelled by a transversely isotropic homogeneous elastic shell. In order to estimate changes of the IOP readings obtained by GAT and MAT after hyperopia surgery the problem of deformation of the cornea under the load with a flat base is considered. The IOP readings before and after the surgeries for two types of tonometers are compered for the same value of true IOP.

dc.description.abstract

value: The influence of the parameters of annular layer which is removed in surgical LASIK and IntraLASIK correction of hyperopia on the changes of the stress-strain state of the cornea is analized. The elastic system cornea-sclera is presented as two conjugate transversely isotropic spherical segments loaded by internal pressure. In order to estimate changes of the intraocular pressure measurements obtained by Goldmann (GAT) and Maklakov (MAT) applanation tonometers after hyperopia surgery, the problem of deformation of the cornea under the load with a flat base is considered. A comparison of the results of two different operations and a comparison of two methods of measuring intraocular pressure for each of these operations is carried out using in all cases the same true intraocular pressure. As a result of the finite element simulation, it was found that reduction in the cornea thickness as a result of annular layer removing during hyperopia surgical correction reduces the flexural rigidity of the cornea and, as a consequence, leads to decrease in the intraocular pressure readings obtained by GAT and MAT. According to calculations, the changes in the intraocular pressure readings depend on the inner and outer diameters of the annular layer, on the depth of the ablation zone, and on the thickness of corneal flap. Nevertheless it was obtained than changes in the intraocular pressure readings obtained by MAT are significantly less than changes obtained by GAT. Numerical calculations have shown the advantage of the IntraLASIK refractive correction of hyperopia compared to the LASIK correction. Because of the fact that during the LASIK surgery the annular layer with smaller inner and outer diameters is ablated and thicker corneal flap is cut, larger deformations and displacements in the thinning region of the cornea, as well as greater decrease of the flexural rigidity of the cornea, have been observed.

dc.description.abstract

value: As shown for many languages, words are lengthened at ends of major prosodic boundaries, and the lengthening effect is most prominent at ends of intonational phrases and utterances. However, it is not clear whether the deeper boundary—end of utterance—shows more lengthening than the other one—end of intonational phrase. The present paper is aimed at answering this question by analysing the duration of Russian stressed and post-stressed vowels in open and closed syllables in words immediately preceding prosodic boundaries; the study is based on corpus data. The results show that for most speakers boundary depth only affects the lengthening of absolute-final vowels, either stressed or post-stressed; vowels in closed or penultimate syllables show similar lengthening effect for both types of boundaries. Additionally, our data show that in Russian stressed vowels are the main carriers of final lengthening, compared to post-stressed vowels.

dc.description.abstract

value: A method of platinum quantification in whole blood samples after microwave digestion using sector field inductively coupled plasma mass spectrometry has been developed. The following analytical figures of merit have been established: limit of detection 1.1 μg/L for blood samples, dynamic range 3.6-200 μg/L, intra-day precision (relative standard deviation, n = 9) did not exceed 5%. Spiked samples were analyzed for method validation. The method was used for pharmacokinetics studies of a novel anti-cancer drug BP-C1, a complex of cis-configured platinum and benzene-poly-carboxylic acids. Main pharmacokinetic parameters (area under curve, maximum concentration, clearance, half-life times for α- and β-phase) were estimated for two dosage forms of BP-C1 0.05 and 0.125 mass %. Pharmacokinetic curves were assessed for single and course administration. Studies were performed using rabbits (n = 6) as a model. BP-C1 was injected intramuscularly. The study established dose proportionality of the tested dosage forms and suggested clinical dosing schedule: 5 days of injections followed by 2 days' break. Platinum tissue distribution was studied in tissue samples collected 20 days after the last injection. Predominant platinum accumulation was observed in kidneys, liver, and muscles near injection site. 'Slow' phase of platinum excretion kinetics may be related to the muscles at the injection site.

dc.description.abstract

value:
Transformations of 2-azabuta-1,3-dienes, formed in Rh2(OAc)4-catalyzed reactions of diazo carbonyl compounds with 2H-azirines, dramatically depend on the nature of substituents. 4,4-Diphenyl-2-azabuta-1,3-dienes with two electron-acceptor substituents at C1 undergo thermal 1,5-cyclization to give indoles in good yields. The increase in electronwithdrawing ability of C1-substituents facilitates the reaction that proceeds via pseudopericyclic 1,5-electrocyclization of 2-azabutadiene into 7aH-indolium ylide followed by prototropic
shift. 3,4-Diphenyl-2-azabuta-1,3-dienes, resulting from reaction of 2,3-diphenyl-2H-azirine and diazo compounds, do not produce indoles via 1,5-cyclization due to the trans-configuration of the 4-Ph-group and the nitrogen, but undergo 1,4-cyclization to 2,3-dihydroazetes. 1,6-Cyclization into 2H-1,4-oxazines with participation of the oxygen of ester or amide group at C1 of corresponding 2-azabuta-1,3-dienes does not take place due to kinetic and thermodynamic reasons. Instead of this, 1,6-electrocyclization with participation of phenyl substituent at C4 of the 2-azabuta-1,3-dienes, providing isoquinoline derivatives, can occur at elevated temperatures. The DFT-calculations (mPWB1K/6-31+G(d,p)) confirm the dependence of 2-azabuta-1,3-diene transformation type on the nature of substituents.

isolated yield. Compounds 1–4 were characterized by elemental analyses (C, H, N), high resolution
ESI+-MS, IR, 1H and 13C{1H} NMR spectroscopic techniques, and by single-crystal X-ray diffraction for 1
and 2. Coordination polyhedra of these two complexes are intermediate between tetrahedral and trigonal
pyramidal with three isocyanide and one bromide ligands; the fragment M–C–N is bent [171.2(2)–
175.6(2) ]. The influence of crystal packing effects on the geometric parameters of 1 as well as nature
of the coordination Cu–C bonds and bond order of the formal triple C„N bonds in this compound were
also studied theoretically at the DFT level of theory. The crystal packing effects noticeably affect the values
of the Cu–C–N angles and lead to a decrease of these angles approximately 10  relative to the gas
phase geometries. Results of the AIM, NBO, and CDA analyses reveal that the Cu–C coordination bonds
are of the electrostatic nature. Electrostatic interaction, unlike the covalent one, has no orientation,
and it is the reason of the curved shape of the metal–ligand fragment.

value: Nickel(II)-mediated coupling between the cyanamide Me2NCN and the ketoximes Me(R)C=NOH (R = Me, Ph) gives chelates of the general formula [NiClx(H2O)(y){HN=C(NMe2)(ON=C(R)Me)}(2)](n+) ([1](+): R = Me; x = 1, y = 0; salts with both Cl- and [NiCl4](2-) were isolated; [2](2+): R = Me; x = 0, y = 2; salt with Cl- was isolated; [3](+): R = Ph; x = 1, y = 1; salt with Cl- was isolated) and the iminium salts [H2N=C(NMe2)ON=C(R)Me](+) ([4](+): R = Me; salt with [NiCl4](2-) was isolated; [5](+): R = Ph; salt with Cl- was isolated). This reaction demonstrates the difference in the reactivity between conventional nitriles and dialkylcyanamides: whereas nitriles RCN (R = Alk, Ar) react with Ni-II/ketoxime systems to afford (1,3,5-triazapentadiene)Ni-II species, formed by postulated nitrile-oxime coupling intermediates, cyanamides under the same conditions give either stable cyanamide-oxime coupling products or the Busch-type complex [Ni{HN=C(Me)CH2C(Me-2)NH2}(2)]Cl-2 ([6]Cl-2). The reason for the different stability of the coupling products was interpreted theoretically on the basis of quantum chemical calculations (M06-L/6-31G* level of theory). The NMe2 moiety in the chelate ligands leads to an increase in electron-density delocalization and also stabilizes the systems in terms of electrostatic factors.

value: Journal of Organometallic Chemistry 797 (2015) 8-12

dc.description.abstract

value: The hard and soft acids and bases (HSAB) principle together with the density functional theory (DFT) calculations were used to analyze the driving forces of the hypothetical 1,3-dipolar cycloaddition (CA) of the nitrone CH2=N(Me) O to the uncomplexed C  NMe and to isocyanide ligands in various transition metal complexes. The calculated activation (Delta G(s)(not equal)) and reaction (Delta G(s)) energies depend from the electronic chemical potential (mu), the global electrophilicity (omega) and nucleophilicity (N) indexes of the dipolarophiles, the static charge transfer "nucleophile -> electrophile" (Delta N-0), and the maximum amount of electronic charge that the electrophile system may accept (Delta N-max). Thus, the HSAB principle may be successfully apply for the study of reactivity of such compounds. The Delta G(s)(not equal) and Delta G(s) and the calculated stretching vibration frequencies v(C  N) of isocyanides well correlated with each other, i.e. higher values of v(C  N) correspond to lower values of Delta G(s)(not equal) and Delta G(s). The application of the reactivity descriptors discussed in this work is a possible alternative and a complement addition to the estimates based on the classical frontier molecular orbital (FMO) theory.

The results of laboratory experiments on specimens without and with notch for a wide range of loading parameters are given. Strength and deformation characteristics of gabbro-diabase were determined experimentally at high strain rates up to 103 s-1. Mechanical characteristics were found to be strongly depended on the strain rate. A uniform interpretation of the rate effects of fracture of the tested gabbro-diabase is given on the basis of structural-temporal approach based on a set of fixed material constants. It is shown that temporal dependences of both the compressive and tensile strengths of the tested material can be effectively calculated using the incubation time fracture criterion.

Studies of the phase and chemical equilibria in the systems where components chemically react cover a wide range of problems related to both experimental determination of physicochemical characteristics of these systems and various aspects of thermodynamic analysis of the phase and chemical processes occurring there. The main goal of this review consists in systematization and analysis of available experimental data concerning the vapour ± liquid and liquid ± liquid equilibria in multicomponent systems where chemical reactions occur. The studies considered here have been mainly published in recent years, and they include rather detailed data on physicochemical properties, phase transitions and chemical processes in fluid systems, i.e., the data which are essential for thermodynamic analysis. Available approaches to the thermodynamic analysis
of heterogeneous systems with chemical reactions are also discussed. Particular attention is paid to the studies of the simultaneous phase and chemical equilibria. We hope that this review could be useful both for fundamental studies of heterogeneous reaction systems and for solving applied problems on the design of combined reaction and mass-transfer processes.The bibliography includes 79 references.

In the present work,we suggest a novel method for obtaining interpolyelectrolyte complex (IPEC) by free radical
polymerization in water–salt dispersions of polyelectrolyte complexes (PECs) based on an anionic polyelectrolyte
(sodium salt of poly (2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS-Na)) and a cationic surfactant
((11-acryloyloxy) undecyl)-trimethylammonium bromide (AUTAB), as well as on PAUTAB cationic comblike
polyelectrolyte and AMPS-Na monomer. IPEC consisting of PAMPS and PAUTAB was obtained by two
ways. The first one is polymerization of surface active monomers AUTAB in the presence of PAMPS, and the second
one is polymerization of AMPS monomers in the presence of PAUTAB. Molecular hydrodynamics methods
were used to determine the molecular properties of initial components, polyelectrolyte complexes (PECs), and
IPECs. Analysis of the dependence between translational friction coefficient of macromolecules and theirmolecular
masses (which takes into account excluded-volume effects) allowed us to determine the Kuhn segment
length of PAMPS-Na macromolecule (A = 6 nm). Stable polyelectrolyte complexes, PEC, (PAMPS–AUTAB and
PAUTAB–AMPS) were obtained by mixing solutions of components at low concentrations in equimolar ratios;
polymerization of their low molecular weight components was carried out for the purpose of preparing IPECs.
Comparison between scattered light intensity distributions measured for PEC and IPEC demonstrated that in
IPEC solutions, only large aggregates of complex molecules are present, while in PEC solutions, two peaks were
observed (those corresponding to diffusion of individual PECs and their aggregates). When concentrations of
PEC components exceed 3.4 mM, polymerization results in the formation of IPEC precipitate which was studied by small angle X-ray scattering. It was found that the IPEC based on PAMPS-Na forms a film with hexagonal packing, and the PAUTAB-based IPEC forms a lamellar film.

cetyltrimethylammonium 2-acrylamido-2-methylpropane sulfonates
were polymerized in water-dioxane mixtures in a wide
range of concentrations of the solvents and in some organic
solvents as well. The resulting polyelectrolyte-surfactant complexes
precipitated from water-dioxane mixtures. Molecular
weights and polymerization yields of the products were the
highest at high and low water contents in the reaction mixture,
whereas the lowest polymerization degrees and yields conform
to solutions, containing 20 % of water. It has been found
that the morphology of the precipitated aggregates formed in
low-polarity solvents differs considerably from that formed in
water. Polymerization in organic media depends strongly on
the polarity of the solvent. Contributions of electrostatic and
hydrophobic interactions in the structure formation of the
complexes were estimated qualitatively.

dc.description.abstract

value: The 1,3-dipolar cycloaddition of acyclic 2-diazo-1,3-dicarbonyl compounds (DDC) and thioketones preferably occurs with Z,E-conformers and leads to the formation of transient thiocarbonyl ylides in two stages. The thermodynamically favorable further transformation of C=S ylides bearing at least one acyl group is identified as the 1,5-electrocyclization into 1,3-oxathioles. However, in the case of diazomalonates, the dominating process is 1,3-cyclization into thiiranes followed by their spontaneous desulfurization yielding the corresponding alkenes. Finally, carbocyclic diazodiketones are much less reactive under similar conditions due to the locked cyclic structure and are unfavorable for the 1,3-dipolar cycloaddition due to the Z,Z-conformation of the diazo molecule. This structure results in high, positive values of the Gibbs free energy change for the first stage of the cycloaddition process.

Binodal surface and curves, tie-lines and compositions of critical points of LLE were determined. Experimental LLE data were correlated by NRTL model. Experimental LLE data were compared with the values calculated by NRTL models, these data are in good agreement.

title: Rydberg-state mixing in the presence of an external electric field: Comparison of the hydrogen and antihydrogen spectra

value: Solovyev, Dmitryi

dc.description.abstract

value: We analyze the influence of an external electric field on the ns and np Rydberg states. The impact of an electric field leads to a significant modification of the decay rate. Namely, the additional (linear and quadratic in the field) terms arise in the differential transition probabilities. In contrast to the quadratic term, the linear summand leads to a difference of the hydrogen (H) and antihydrogen (H¯) spectra. However, this difference vanishes after the integration over photon-emission directions and does not contribute to the total emission probability. The quadratic term results in the significant change of the total decay rate and level width, respectively. The analysis of the linear and quadratic terms depending on the field strength is discussed.

dc.description.abstract

value: Chemical equilibrium (CE) for the quaternary reactive system of acetic acid–n-butanol–n-butyl acetate– water was studied at 308.15 K and atmospheric pressure. The experimental data on CE were considered in comparison with the data on liquid–liquid equilibrium: the CE is reached both in homogeneous and heterogeneous area of reactive mixture compositions. The crossing of CE and binodal surfaces is presented in a composition tetrahedron and a square of transformed composition variables. The thermodynamic constant of CE at 308.15 K was determined with the use of NRTL and UNIQUAC models.
