Ferrocenium salts [(C 5 H 5 ) 2 Fe]X (X = BF 4 , PF 6 ) ( I + · ) react with tertiary phosphines PR 3 (PMe 3 , PEt 3 , P n Bu 3 , PMe 2 Ph, and PMePh 2 ) in dichloromethane at room temperature to form a mixture of the corresponding ferrocenylphosphonium salts [(C 5 H 5 )FeC 5 H 4 PR 3 ]X ( III ), ferrocene ( I ), and phosphonium salts [HPR 3 ]X. The same reaction was carried out in an electrochemical cell as the electrolysis of a solution of ferrocene and phosphine in dichloromethane at the oxidation potential of ferrocene. Possible reaction ...

Abstract The paper deals with the elaboration of the algorithm for multicomponent gas flows simulation in the presence of strong shock waves. In order to deal with strong shock wave properly the exact Riemann solver for multicomponent flow and non-perfect gases is used. Standard finite volume Godunov-type scheme gives the effect of numerical pressure oscillations on a contact discontinuity. In order to fix the situation the convenient modification of double flux method is described and tested. The ...

The paper describes unexpected properties of hypercross-linked polystyrenes with ultimate cross-linking degrees of 300, 400, and 500%, where three, four, or five methylene links, respectively, could bind each polystyrene phenyl ring to its spacious neighbors. The polymers exhibit a strong electron spin resonance signal, unusual spectra in IR, UV, and visible ranges, and they are not typical dielectrics. The nonfunctionalized hypercross-linked polymers absorb significant amounts of inorganic acids, ...

In this paper, we analyzed B chromosome variation in Korean field mouse Apodemus peninsulae Thomas 1907 (Rodentia, Muridae) based on a 40-year study of karyotypes collected from geographically distant populations in East Siberia, North Mongolia, China, the Russian Far East, and Japan (Hokkaido). We developed the database of individual variants of B chromosome systems in A. peninsulae. In Siberian populations all animals had Bs. The karyotypes of the studied animals contain from 1 to 30 Вs differing ...

We revealed two vast areas of polymorphism for diagnostic chromosomes of karyotypic races Białowieża (gr, hn, ik, mp) and Kiev (gm, hi, ko) with low frequency of metacentrics. The frequencies of the Białowieża diagnostic metacentrics decreased towards the east and the frequency of the Kiev metacentrics decreased towards the north. A high level of chromosomal ...

C(60) was reacted in the ionization chamber of a mass spectrometer under electron impact (EI) with aldehydes, RCHO (R = Ph, p-FC(6)H(4), F(5)C(6), p-MeOC(6)H(4), α-thienyl, o-HOC(6)H(4), o-BrC(6)H(4), m-BrC(6)H(4) and t-Bu), with the transfer of R• radicals and with Me•-transfer from i-PrCHO and t-BuCHO. Paramagnetic fullerene derivatives were stabilized by the addition of the next R• radical or a hydrogen atom, or hydrogen or bromine atom loss. A detailed study showed that the reaction between C(60) ...

Abstract Signalling pathway activation analysis is a powerful approach for extracting biologically relevant features from large-scale transcriptomic and proteomic data. However, modern pathway-based methods often fail to provide stable pathway signatures of a specific phenotype or reliable disease biomarkers. In the present study, we introduce the in silico Pathway Activation Network Decomposition Analysis (iPANDA) as a scalable robust method for biomarker identification using gene expression data. ...

The G-banded karyotype of S. satunini was compared with the karyotype of Sorex araneus. Extensive homology was revealed. The major chromosomal rearrangements involved in the evolutionary divergence of these species have been identified as centric fusions and centromeric shifts. From the known palaeontological age of S. satunini it is obvious that the vast chromosomal polymorphism of the S. araneus group originated during the middle Pleistocene.

Analysis of the frequency of karyotypes and chromosomal rearrangements in the distributional ranges of four metacentric races of Sorex araneus Linnaeus, 1758 has revealed features that are not typical for polymorphic populations of this species. The frequency of the acrocentric karyotype and heterozygotes for fusion of acrocentric chromosomes turned out to be significantly higher than expected in case of random crossing. As an explanation for the unusual polymorphism, it has been suggested that ...

The behavior of N-methylidenemalonates of 3-arylaminoindoles and p-dimetylamino-N-phenylanyline (M = ANa) was studied during their analysis with ESI mass spectrometer operated in negative (NI) and positive (PI) ion modes. Anions [A] and both [M + H]+ and [M + Na]+ were recorded under conditions of the NI-ESI and PI-ESI, respectively. The fragmentation processes of [A] and [M + H]+ were found that probably occurred as "insource collusion induced dissociation". The main paths for [A] proved to be elimination of CO2 ...

The application of dielectric measurements for the characterisation the crosslinking process is considered. Possibilities and problems of the method are discussed. It is proposed to use microwave methods in the case when low frequency methods can not characterise the crosslinking process. To prove the efficiency of the microwave methods a number of thermosets (urea, melamine, melamine-phenolic and phenolic resins) during curing and elastomers (carbon black filled rubbers) during vulcanisation was ...

The morphology of virgin reactor powder (RP) of high-density polyethylene (HDPE) with MW = 160,000 g/mol was investigated using DSC, SEM, SAXS, and WAXS methods. The morphological SEM analysis showed that the main morphological units of RP are macro- and micro-shish-kebab structures with significantly different geometric dimensions, as well as individual lamellae of folded chain crystals. A quantitative analysis of an asymmetric SAXS reflection made it possible to reveal the presence of several periodic ...

The system of Navier–Stokes equations for a multicomponent reacting gas is used as a mathematical model; chemical reactions are described by a detailed kinetic scheme. The general solution algorithm is based on the splitting scheme for the types of processes under consideration: convection–diffusion–chemical reactions, an approach ...
