Rationale is determined by rapid lexical growth of English language, caused by processes of integration and globalization, and up-to-date lack of research in neology. The determination of euphemistic neologisms translation distinctions is subject to future research, aimed to unhide its way of creation. The necessity of studying neologisms in English and Ukrainian languages is based on a great amount of uncharted word-borrowing processes and incomplete key notions determinations. Terms and types of neologisms and euphemisms have been determined as contents those form the notion of euphemistic neologism. Different ways of neologisms and euphemisms classifications were examined. In addition to this, specifications of its formation and use have been examined, based on English language publicistic texts, such as interview, articles, reportages those are published in world-wide BBC Corporation. Euphemistic neologisms general functionality in English and Ukrainian languages has been studied out, translation methods and transformations those are used by author, solving communicative tasks, have been determined. Particular attention has been paid to analysis of euphemistic neologism functions in English language and to methods and transformations of its translation into Ukrainian language. The quantitative analysis results of performed research are produced in current paper.ΠΠ°Π½Π½Π°Ρ ΡΡΠ°ΡΡΡ ΠΏΠΎΡΠ²ΡΡΠ΅Π½Π° Π°Π½Π°Π»ΠΈΠ·Ρ Π°Π½Π³Π»ΠΈΠΉΡΠΊΠΈΡ

Β© 2015, Pleiades Publishing, Ltd. Electrochemical properties of the [NiBr2(bpy)2] complex, where bpy = 2,2β²-bipyridyl, have been studied in the presence of derivatives of ortho-phosphine phenol: 2-diphenyl phosphanyl-4-methyl phenol CH3C6H3(PPh2)OH (1), 2-diphenyl phosphanyl-4-methylphenyldiphenyl phosphinate CH3C6H3(PPh2)OP(O)Ph2 (2), and 2-diphenylphosphoryl-4-methyl phenol CH3C6H3(P(O)Ph2)OH (3). It is found that interaction of products of electrochemical reduction of complex [NiBr2(bpy)2] with 1 and 2 results in formation of active catalysts of the process of homogeneous oligomerization/polymerization of ethylene
Tracking of the formation of binuclear nickel complexes of [Ni<inf>2</inf>(Β΅-O<inf>2</inf>PR<sup>1</sup>R<sup>2</sup>)<inf>2</inf>(bpy)<inf>4</inf>]Br<inf>2</inf> type by ESI and MALDI mass spectrometry
Β© 2017 Elsevier LtdThe formation of binuclear nickel complexes of type [Ni2(Β΅-O2PR1R2)2(bpy)4]Br2, where R1Β =Β H, R2Β =Β phenyl (Ph), 2,4,6-trimethylphenyl (Mes), 2,4,6-triisopropylphenyl (Tipp) or R1R2Β =Β [sbnd]OCH2CH(Et)NHCH(Ph)[sbnd]; bpyΒ =Β 2,2β²-bipyridine, in solution and their fragmentation behavior have been investigated by ESI and MALDI mass spectrometry. It was found that binuclear cationic fragments [Ni2(Β΅-O2PR1R2)2(bpy)2Br]+ are characteristic ions displaying the formation of binuclear nickel(II) complexes in solution
Electrochemical properties and reactivity of organonickel sigma-complex [NiBr(Mes)(bpy)] (Mes = 2,4,6-trimethylphenyl, bpy = 2,2β²-bipyridine)
Β© 2015, Pleiades Publishing, Ltd. Electrochemical properties and reactivity of electrochemically activated forms of organonickel sigma-complex [NiBr(Mes)(bpy)] (where Mes = 2,4,6-trimethylphenyl, bpy = 2,2β²-bipyridine) were studied. The activation of the organonickel sigma-complex was found to proceed under both electrochemical reduction and oxidation conditions to give coordinatively unsaturated forms of the complex: radical [Ni(Mes)(bpy)]β’ and cationic complex [Ni(Mes)(bpy)]+, respectively. It was shown experimentally that the active forms of organonickel complex [NiBr(Mes)(bpy)] can react with organic substrates (cyclohexene, octene-1, tetrahydrofuran) and convert nitriles (acetonitrile, acetonitrile-d3, chloroacetonitrile) into corresponding imines containing 2,4,6-trimethylphenyl fragment
Comparative analysis of the binding of thiacalix[4]arene-monocrown-ethers with monovalent metal salts using MALDI mass spectrometry
Β© 2016, Pleiades Publishing, Ltd.MALDI mass spectrometry is used for the first time for the rapid assessment of the binding of thiacalix[4]arene-monocrown-ethers with metal cations (Li, Na, K, Cs, Cu, Ag). The work is performed on examples of thiacalix[4]arene-monocrown-ethers in 1,3-alternate conformation with various numbers (m) of ethylene oxide units and various substituents in phenol groups. It is shown that thiacalix[4]arene-monocrown- ethers with m = 3, 4, 5, and 6 bind lithium, sodium, potassium, and cesium cations, respectively; in addition, the binding of cesium cations is stronger in the presence of aromatic substituents in the lower rim of thiacalix[4]arene-monocrown-ethers. Silver cations bind with calixarenes under study more intensely than copper ions. When aromatic substituents are present, the binding of silver cations is stronger than that of alkali metal ions with the studied thiacalix[4]arene-monocrown-ethers
Echocardiographic screening of children and teenagers during routine physical examination
Objective: to study the frequency of occurrence of diseases of the cardiovascular system in the course of routine physical examination of the child population, with the purpose of early recognition of various pathological conditions, including structural anomalies of the heart and large vessels.Material and methods: total examined 260 childrens aged 6 to 14 years, 118 girls (45.3 %) and 142 boys (54.6 %). Screening survey was performed in the parasternal, apical and subcostal positions. Time to research occupied from 7 to 20 minutes.Results: out of 260 children who passed clinical examination a structural anomalies of the heart was detected in 56 patients (21,5 % of all researches).Conclusions: the clinical examination of children population has a colossal medical and social important not only in Russia, but all over the world. Echocardiographic screening of children of preschool age is necessary for timely detection of cardiovascular pathology, especially occurring asymptomatically
The formation of secondary arylphosphines in the reaction of organonickel sigma-complex [NiBr(Mes)(bpy)], where Mes = 2,4,6-trimethylphenyl, bpy = 2,2β²-bipyridine, with phenylphosphine
Β© 2016 Taylor & Francis Group, LLC.The reactivity of organonickel sigma-complex [NiBr(Mes)(bpy)], where Mes = 2,4,6-trimethylphenyl, bpy = 2,2β-bipyridine towards phenylphosphine (PhPH2) has been investigated. It was found that this interaction leads to secondary mesitylphenylphosphine and dimesitylphosphine by formation of new carbon-phosphorus bond involving mesityl fragment of starting organonickel sigma-complex
First example of organonickel complex bearing three cyclic substituents in the Ο-bonded aromatic ring: Bromo[(2,2' -bipyridine)-2,4,6-tricyclohexylphenylnickel]
Β© 2016 Mendeleev Communications. Published by ELSEVIER B.V.The electrochemical reduction of [NiBr2(bpy)] (bpy is 2,2'-bipyridine) complex in the presence of 2,4,6-tricyclohexylphenylbromide (TchpBr) in undivided electrochemical cell supplied with a sacrificial nickel anode results in the one-pot formation of an organonickel complex [NiBr(Tchp)(bpy)] bearing three cyclic substituents in the s-bonded aromatic ring. The synthesized complex was characterized by various methods including single crystal X-ray analysis
Nonperturbative XY-model approach to strong coupling superconductivity in two and three dimensions
For an electron gas with delta-function attraction we investigate the
crossover from weak- to strong-coupling supercoductivity in two and three
dimensions. We derive analytic expressions for the stiffness of phase
fluctuations and set up effective XY-models which serve to determine
nonperturbatively the temperature of phase decoherence where superconductivity
breaks down. We find the transition temperature T_c as a monotonous function of
the coupling strength and carrier density both in two and three dimensions, and
give analytic formulas for the merging of the temperature of phase decoherence
with the temperature of pair formation in the weak-coupling limit.Comment: Few typos corrected. Emails that were sent to the address
