Ultrasonic fingerprinting by phased array transducer

Increasing quantity of spent nuclear fuel that must be under national and international control requires a novel approach to safeguard techniques and equipment. One of the proposed approaches is utilize intrinsic features of casks with spent fuel. In this article an application of a phased array ultrasonic method is considered. This study describes an experimental results on ultrasonic fingerprinting of austenitic steel seam weld

Using the scenarios of simulation case assignments in the educational process of students in the specialty "State and Municipal Management", master's degree programme

The article is devoted to the use of simulation case assignments in the learning process of students pursuing a Master's degree in "State and Municipal Management" at Russian State Social University. This university was established in 1991 for the high-quality training of specialists in the social sphere. The specialty "State and Municipal Management" enables students to explore the theoretical and practical levels, the essence and features of management interactions in the system of state and municipal administration, the main objectives, tasks and mechanisms of governance at the state and municipal levels, the methods and means of attracting investments in the economy of the municipality and the region, the features of the management system of the asset portfolio. The discipline "Sociology of Management" is the base for the direction of training "State and Municipal Management". The knowledge and skills acquired during the study contribute to a better understanding of the social, political, and economic patterns of management processes. Management sociology is a science which summarizes all management sciences in terms of targeting and special study of the patterns of managerial relations at all levels of society and its elements' functioning, as well as in all subject areas, the spheres of activity in society. The study of sociology as a science about relationships in the process of governance, connections, and interactions of the subjects of management activity in Russia has started relatively recently. In the mid-1990s, scientific readings and conferences were focused on the definition of the substantive field of science, its structure. Over these years, the situation has been as follows. The sociologists who violently debated and developed this scientific direction, after the appearance of the specialty "Management in Social Sphere" in 1996, in 1999 - the specialty "State and Municipal Management", and in 2002 - the specialty "Personnel Management", handed the study of this discipline to managers. And all of these management specialties found themselves in the consolidated group of professions "Economics and Management". This greatly affected the gap in the subject field of management itself. Most economists imagined that management is economics. The lawyers of those universities where departments of "Public Administration and Legal Support" were established never doubted that management is a legal sphere of activity. None of them paid special attention to the sociological component. However, those universities, which in the course of training in the field of state and municipal government created departments of sociology management in their structure or modules in the curricula, provide the most high-quality preparation of future managers. © 2018 Authors

Synthesis of Euchrestifoline Using Iron- and Palladium-Catalyzed C–H Bond Activations

© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim We describe a short and efficient synthetic route to euchrestifoline. Key steps of our approach are the iron(III)-catalyzed Wacker-type oxidation of a chromene derivative with hexadecafluorophthalocyanine-iron (FePcF16) as catalyst, a palladium(0)-catalyzed Buchwald–Hartwig amination, and the final palladium(II)-catalyzed oxidative cyclization of the resulting diarylamine to the natural product

Enantioselective Total Synthesis and Assignment of the Absolute Configuration of the Furo[3,2- a]carbazole Alkaloid Furoclausine-B

© Copyright 2018 American Chemical Society. We describe the first enantioselective total synthesis and the assignment of the absolute configuration of the furo[3,2-a]carbazole alkaloid furoclausine-B. As key steps for our approach we used a palladium(II)-catalyzed double C-H-bond activation for the construction of the carbazole framework, a Shi epoxidation, and an intramolecular opening of the epoxide for annulation of the dihydrofuran moiety

A new surfactant-copper(ii) complex based on 1,4-diazabicyclo[2.2.2]octane amphiphile. Crystal structure determination, self-assembly and functional activity

© the Owner Societies 2018. A new surfactant-copper(ii) complex [Cu(L)Br3] (where LBr is 1-cetyl-4-aza-1-azoniabicyclo[2.2.2]octane bromide) containing a transition metal in the head group has been synthesized and characterized. Physicochemical properties, thermal stability and 3D structure were determined using X-ray diffractometry, UV-vis spectroscopy, simultaneous thermogravimetry and differential scanning calorimetry combined with mass-spectrometry of evolved vapors. The study of the self-assembly and morphological features of associated structures was performed by potentiometry using a bromide ion selective electrode and fluorescence of pyrene and 1,6-diphenyl-1,3,5-hexatriene. The influence of the metal ion embedded into the surfactant structure on critical micelle concentration, degree of counterion binding, aggregation numbers and morphology of the associates was elucidated. High solubilizing capacity and complexation ability of the metal containing micelles with respect to Orange-OT hydrophobic dye and oligonucleotide were determined. Importantly, the functional properties of this metallosurfactant complex are much better compared to those of classical cationic surfactants bearing cyclic and acyclic head groups, LBr and the LBr-CuBr2 mixture. The new cationic metallosurfactant could be recommended for investigation in gene therapy

Synthesis of new N-acylantipyrylureas and the crystal structure of N-benzoyl-N′-[4-(2,3-dimethyl-1-phenylpyrazol-5-one)]urea

New derivatives of acylheterylureas were synthesized by reactions of acylisocyanates with 4-amino-2,3-dimethyl-1-phenylpyrazol-5-one. The structures of the compounds obtained have been established by IR and 1H NMR spectroscopy. N-Benzoyl-N′-[4-(1-phenyl-2,3-dimethylpyrazol-5-one)]urea has been studied by X-ray structural analysis. It was found that the molecule adopts an anti-syn conformation stabilized by an intramolecular hydrogen bond. In the crystal, molecules are linked in centrosymmetric dimers via intermolecular hydrogen bonds. © 1996 Plenum Publishing Corporation

Molecular structure and conformations of eight-membered cyclic acetals with 1,4-diplanar fragments

The molecular structures of nine eight-membered cyclic acetals containing two planar fragments in the ring, the derivatives of dibenzo- and dinaphtho[d,g][1,3]dioxocines, have been studied by x-ray single crystal diffraction. Steric interactions were found to determine the conformation realized in the crystalline phase. Depending on the type of planar fragments in the cycle and the group bridging them, boat-chair (BC), distorted boat (DB), twist (T) or twist-boat (TB) conformations were observed. The BC conformation was found for derivatives of 6H,12H-dibenzo[d,g][1,3]dioxocine containing methyl groups in the benzo fragments or one methyl substituent in the bridge methylene group. The T and TB conformations are realized for molecules with the carbonyl group bridging the planar fragments. 8H,16H-Dinaphtho[2,1-d,1′2′-g][1,3]dioxocine exhibits the first example of BC conformation among all eight-membered cyclic compounds containing two naphtho groups at the expense of large deviations of its geometrical parameters from their unstrained values. Other dinaphtho derivatives exist in the DB conformation. The molecular geometry and the possibility of weak intramolecular CH⋯O hydrogen bonding are discussed. © 1995
