Enantioselective Total Synthesis of (+)-Cassiol
An enantioselective total synthesis of (+)-cassiol is reported. The complex derived from Pd-2(pmdba)(3) and enantiopure t-BuPHOX ligand catalyzes enantioconvergent decarboxylative alkylation to generate the quaternary carbon stereocenter at an early stage. The overall synthetic strategy involves a convergent late-stage coupling of two fragments. The synthesis features a longest linear sequence of eight steps
Theoretical and experimental study of high-pressure synthesized B20-type compounds Mn(Co,Rh)Ge
The search and exploration of new materials not found in nature is one of
modern trends in pure and applied chemistry. In the present work, we report on
experimental and \textit{ab initio} density-functional study of the
high-pressure-synthesized series of compounds Mn(Co,Rh)Ge. These
high-pressure phases remain metastable at normal conditions, therewith they
preserve their inherent noncentrosymmetric B20-type structure and chiral
magnetism. Of particular interest in these two isovalent systems is the
comparative analysis of the effect of (Co) and (Rh) substitution for
Mn, since the orbitals are characterized by higher localization and
electron interaction than the orbitals. The behavior of
Mn(Co,Rh)Ge systems is traced as the concentration changes in the
range . We applied a sensitive experimental and theoretical
technique which allowed to refine the shape of the temperature dependencies of
magnetic susceptibility and thereby provide a new and detailed
magnetic phase diagram of MnCoGe. It is shown that both systems
exhibit a helical magnetic ordering that very strongly depends on the
composition . However, the phase diagram of MnCoGe differs from
that of MnRhGe in that it is characterized by coexistence of two
helices in particular regions of concentrations and temperatures.Comment: 12 pages, 11 figure
Study of olivines from Omolon and Seymchan meteorites using X-ray diffraction and MΓΆssbauer spectroscopy with a high velocity resolution
Study of olivine from Omolon and Seymchan meteorites was performed using X-ray diffraction and MΓΆssbauer spectroscopy with a high velocity resolution. X-ray diffraction patterns were measured at room temperature while MΓΆssbauer spectra were measured at 295 and 90 K. The orthorhombic crystal lattice parameters were evaluated for olivine from Omolon and Seymchan. These parameters appeared to be different for olivines from both meteorites. MΓΆssbauer spectral components related to 57Fe in crystallographically non-equivalent sites M1 and M2 in both olivines were determined and its MΓΆssbauer hyperfine parameters were evaluated. Some differences in the tendencies of temperature dependence of spectral parameters and small variations of 57Fe quadrupole splitting in both M1 and M2 sites of olivines from Omolon and Seymchan were found. On the basis of MΓΆssbauer parameters and chemical data, the temperatures of equilibrium cation distribution were evaluated for both olivines. Β© 2012 American Institute of Physics

VIDEO BLOGGING AS AN INNOVATIVE FORM OF THE PROJECT ACTIVITY IN FOREIGN LANGUAGE TEACHING TO JOURNALISM STUDENTS
Introduction. The appearance of new formats and ways of presenting information inevitably affects the educational process and leads to the necessity to revise the paradigm of pedagogical attitudes and tools of the teaching activity, which in turn generates a number of methodological and didactic problems to be solved. The relevance of the research topic is caused by the current tendency of the distribution of video blogging as an information activity tool that affects the educational environment. There is a steady development of video blogging (a special kind of blog, where the emphasis is made on video information) as a new channel of communication in the educational services market, and using it as a separate form of non-educational project activity within the framework of mastering one or another academic discipline. In the conditions of deficiency of classroom hoursΒ and increase in student independent work, project-based education is becoming more and more demanded type of training. Currently, interdisciplinary projects are being widely disseminated at high school; these projects are aimed at vocational guidance for a foreign language, they meet the requirements of the new communication reality and the needs of modern educational systems. The aim of the publication is to consider video blogging as an innovative form of project-oriented learning a foreign language and to characterize the features of creating and implementing media content within the framework of a foreign language training course. Methodology and research methods. In the course the research, such theoretical scientific methods as analysis, synthesis, concretization, generalization, as well as hypothetical-deductive and design methods were applied. Results and scientific novelty. For the first time the article deals with the structure of video blogging as a project work and as a form of professionally oriented foreign language teaching as well, also there are formulated basic didactic questions in the article. These questions have appeared in the process of the development and the implementation of the media project βEpisch! Deutschβ, created in 2015 within the framework of the subject βGerman languageβ at the Department of Media Linguistics of the Faculty of Journalism of Moscow State University named after M. V. Lomonosov. The conclusion is made that it is necessary to develop methodological criteria and educational standards that regulate video blogging as a way of teaching and methodological work, also a providing an opportunity for development of teachersβ professional qualification. Practical significance. The materials of the present publication can be useful for future and practicing teachers of a foreign language, as well as for other categories of educators engaged in organization of educational project activities.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.

Crystal structure and conductivity of bismuth-containing complex oxides
In the paper, a comprehensive systematic study of different classes of bismuth containing oxide compounds was carried out. The relationship between composition, temperature and concentration regions of existence of stable, specific structure and properties of solid solutions on the basis of vanadates, molybdates, niobates and bismuth was found. The general regularities of synthesis of solid solutions with different variants of solid-phase and soluble methods were determined. On this basis, the optimal conditions for obtaining
single-phase materials were formulated. For the first time the temperature and concentration boundaries of the regions of homogeneity and areas of stable existence of polymorphic modifications of solid solutions were defined and/or refined. The structural parameters of the synthesized phases were determined. By the method of electrochemical impedance spectroscopy the nature and features
of impedance spectra, the temperature and concentration dependences of electrical conductivity of ceramic materials based on bismuth containing complex oxides were identified

MSSM-inspired multifield inflation
Despite the fact that experimentally with a high degree of statistical
significance only a single Standard Model--like Higgs boson is discovered at
the LHC, extended Higgs sectors with multiple scalar fields not excluded by
combined fits of the data are more preferable theoretically for internally
consistent realistic models of particle physics. We analyze the inflationary
scenarios which could be induced by the two-Higgs doublet potential of the
Minimal Supersymmetric Standard Model (MSSM) where five scalar fields have
nonminimal couplings to gravity. Observables following from such MSSM-inspired
multifield inflation are calculated and a number of consistent inflationary
scenarios are constructed. Cosmological evolution with different initial
conditions for the multifield system leads to consequences fully compatible
with observational data on the spectral index and the tensor-to-scalar ratio.
It is demonstrated that the strong coupling approximation is precise enough to
describe such inflationary scenarios.Comment: 27 pages, 4 figures, 5 tables. Version to appear in JHEP. Additions
made to the text of the Introduction dealing with the issues of conformity of
this multifield model and models of N=1 supergravity (pages 2-3). Added new
inflationary scenarios, which are an artifact of such analysis (pages 11-12,
Tables 1-4). Additional comments on page 9 and page 13. New references adde
Preparation and characterization of Bi26β2xMn2xMo10O69-d and Bi26.4Mn0.6Mo10β2yMe2yO69-d(Me = V, Fe) solid solutions
Received: 06.06.2017; accepted: 23.06.2017; published: 14.07.2017.Single phase samples of bismuth molybdate, Bi26Mo10O69, doped with Mn on the bismuth sublattice and V, Fe on the molybdenum sublattice were found to crystallize in the triclinic Bi26Mo10O69 structure at low doping levels and in the monoclinic Bi26Mo10O69 structure - at higher dopant concentration. The assumption that all Mn ions have an oxidation state of +2 was confirmed by means of magnetic measurement results analysis using Curie-Weiss law. Conductivity was investigated using impedance spectroscopy. The conductivity of Bi26.4Mn0.6Mo9.6Fe0.4O69-d was 1.2*10-2 S*cm-1 at 973 K and 2.2*10-4 S*cm-1 at 623 K, and the conductivity of Bi26.4Mn0.6Mo9.2V0.8O69-d was 2.2*10-3 S*cm-1 at 973 K and 2.2*10-5 S*cm-1 at 623 K
