A Coptic Historian and “the Caliph of the Armenians”: Cross-cultural Dynamics and Rhetorical Strategies in al-Mufaḍḍal Ibn abī l-Faḍā’il
No full textIn narrating the Mamluk conquest of the Armenian stronghold of Hṙomkla (1292 AD), see of the Armenian Catholicosate, the Egyptian Coptic historian al-Mufaḍḍal Ibn Abī l-Faḍā’il (d. after 1358) described the Catholicos as “Caliph of the Armenians” (khalīfat al-Arman), instead of using the more common expression “Patriarch of the Armenians” (baṭrak al-Arman).
On the one hand, the wording “Caliph of the Armenians” was not completely new and it had already been used by the Muslim historian Ibn al-Dawādārī, who was al-Mufaḍḍal’s direct source on this event. On the other hand, close textual and contextual analysis of al-Mufaḍḍal’s work suggests that, in using such formula, this Coptic author was not passively following his Muslim source but making a deliberate choice, most plausibly related to his peculiar vision of interreligious relations in Mamluk Egyptian society, against the background of the system of “discriminating protection” (dhimma) that was applied to Christians and Jews under Islamic rule.
Although systematic examination of representations of religious diversity throughout al-Mufaḍḍal’s work is still to be done, the elements analyzed so far seem to indicate that al-Mufaḍḍal aimed at connotating foreign Christian communities in ethnic and political terms rather then in religious term, so as to “dechristianize” their image in the eyes of the Muslim “public opinion”. This may be understood as a rhetorical strategy instrumental to deny any possible association between foreign Christian groups – that were actual or potential enemies of the Mamluk “State”- and the Egyptian Coptic Christians, that al-Mufaḍḍal constantly represented, conversely, as loyal subjects and supporters of the Mamluks and of the socio-political order that the Sultan “embodied” and preserved
Quantitative theory of diffraction by cylindrical scroll nanotubes
No full textA quantitative theory of Fraunhofer diffraction by right- and left-handed multiwalled cylindrical scroll nanotubes is developed on the basis of the kinematical approach. The proposed theory is mainly dedicated to structural studies of individual nanotubes by the selected-area electron diffraction technique. Strong and diffuse reflections of the scroll nanotube were studied and explicit formulas that govern relations between the direct and reciprocal lattice of the scroll nanotube are achieved.</jats:p
Ideological and artistic features of Azat Abdullin's dramas
No full textThis article provides a comprehensive analysis of the stage works by the Bashkir playwright, publicist, people's writer of the Republic of Bashkortostan Azat Abdullin "Do not forget me, sun!" and "Garden from Nowhere", dedicated to the creation of an artistic portrait of famous personalities of Russian literature and ballet art with tragic fates such as Sergey Chekmarev and Rudolf Nureyev. The study explored ideological-thematic, problematic, genre-style, plot-compositional features of the works, the writer's skill in revealing the inner world and creating psychological portraits of the characters. With the drama "Do not forget me, Sun!" the playwright entered literature in the 1960s. The psychological drama “The Thirteenth Chairman” written in the 1970s made him famous. The author also wrote the continuation of the drama "The Last Patriarch". The dilogy marked the resurrection of the method of critical realism even before the onset of the reform of the 1980s. Over the last decades of the 20th century, Bashkir playwrights created stage works. These plays were highly appreciated by specialists, loved by the audience and awarded high government awards. The play "Bibinur, ah, Bibinur!" by Florida Bulyakova was one of the first to be awarded the State Prize of the Russian Federation (1980). The dramatic trilogy "Validi" by N. Asanbaev about Akhmet-ZakiValidiTogan is a landmark work which became a truly creative discovery in modern Bashkir literature. One more creative achievement of the Bashkir authors was the play by the same AzatAbdullin– the drama “An Otherworldly Garden

Misfit Layered Compounds: Insights into Chemical, Kinetic, and Thermodynamic Stability of Nanophases
No full textCompounds with layered structures (2D-materials), like transition metal-dichalcogenides (e.g., MoS2), attracted a great deal of interest in the scientific community in recent years. This interest can be attributed to their unique lamellar structure, which induces large anisotropy in their physicochemical properties. Furthermore, owing to the weak van der Waals interaction between the layers, they can be cleaved along the a–b plane, which allows fabricating single layers with physical properties entirely different from the bulk material. Moreover, stacking layers of different 2D-materials on top of each other has led to a wealth of new observations, for instance, by twisting two layers with respect to each other and producing Moiré lattice. Another outstanding property of inorganic layer compounds is their tendency to form nanotubes, reported first (for WS2) many years ago and subsequently from many other layered compounds.Among the 2D-materials, misfit layer compounds make a special class with an incommensurate and nonstoichiometric lattice made of an alternating layer with rocksalt structure, like LaS (O) and a layer with hexagonal structure, like TaS2 (T). The lack of lattice commensuration between the two slabs leads to a built-in strain, which can be relaxed via bending. Consequently, nanotubes have been produced from numerous MLC compounds over the past decade and their structure was elucidated.Owing to their large surface area, nanostructures are generally metastable and tend to recrystallize into microscopic crystallites via different mechanisms, like Ostwald ripening, or chemically decompose and then recrystallize. The stability of nanostructures at elevated temperatures has been investigated quite scarcely so far. In this perspective, electron microscopy as well as synchrotron-based X-ray absorption and reflection techniques were used to elucidate the chemical selectivity and decomposition routes of rare-earth based MLC nanotubes prepared at elevated temperatures (800–1200 °C).As for the chemical selectivity, entropic effects are expected to dictate the random distribution of the chalcogen atoms on the anion sites of the MLC nanotubes at elevated temperatures. Nonetheless, the sulfur atoms were found to bind exclusively to the rare-earth atom (Ln = La, Sm) of the rocksalt slab and the selenium to the tantalum of the hexagonal TX2 slab. This uncommon selectivity was not found in other kinds of nanotubes like WSe2xS2(1–x). In other series of experiments, the lack of utter symmetry in the multiwall nanotubes leads to exclusions of certain X-ray (0kl) reflections, which was used to distinguish them from the bulk crystallites. The transformation of Ln-based MLC nanotubes into microscopic flakes was followed as a function of the synthesis temperature (800–1200 °C) and the synthesis time (1–96 h). Furthermore, sequential high-temperature transformations of the (O-T) lattice into (O-T-T) and finally (O-T-T-T) phases via deintercalation of the LnS slab was observed. This autocatalytic process is reminiscent of the deintercalation of alkali atoms from different layered structure materials. Annealing at higher temperatures and for longer periods of time eventually leads to the decomposition of the ternary MLC into binary metal-sulfide phases, as well as partial oxidation of the product. This study sheds light on the complex mechanism of high-temperature chemical stability of the nanostructures
Nanotubes from Lanthanide-Based Misfit-Layered Compounds: Understanding the Growth, Thermodynamic, and Kinetic Stability Limits
No full textGaining insights into the kinetics and the thermodynamic limits of nanostructures in high-temperature reactions is crucial for controlling their unique morphology, phase, and structure. Nanotubes from lanthanide-based misfit-layered compounds (MLCs) have been known for more than a decade and were successfully produced mostly via a chemical vapor transport protocol. The MLC nanotubes show diverse structural arrangements and lattice disorders, which could have a salient impact on their properties. Though their structure and charge transfer properties are reasonably well understood, a lack of information on their thermodynamic and kinetic stability limits their scalable synthesis and their applicability in modern technologies. In this study, the growth, thermodynamic stability, and decomposition kinetics of lanthanide-based misfit nanotubes of two model compounds, i.e., (LaS)1.14TaS2 and (SmS)1.19TaS2 are elucidated in detail. The nanotubes were carefully analyzed via atomic resolution electron microscopy imaging and synchrotron-based X-ray and electron diffraction techniques, and the information on their morphology, phase, and structures was deduced. The key insights gained would help to establish the parameters to explore their physio-chemical properties further. Furthermore, this study sheds light on the complex issue of the high-temperature stability of nanotubes and nanostructures in general

overview of work that had been done in order for author to develop the final year project.
There will be an in depth discussion of all the findings and also the problems that author
has been facing with the development of this project. The most important sections for this
report are the Literature Review and the Results and Discussions, since they will contain
the bulk of the findings. Initially it was decided that author will concentrate only on the
web application development and then develop the project based on that findings,
however it has now been decided that he will research the various database mechanisms
and thereafter build the application based on the theoretical knowledge that author has
gained from the research but the implementation will be entirely up to the own discretion.
In the sections that follow author will provide all of the aspects that he has been able to
gather up to so far, and also allow the readers to be able to get a better understanding of
the how web application and database works together as a unit
Problematic Issues of Forensic Examinations in the Detection and Investigation of Crimes on Illicit Trafficking of Narcotic Drugs of Plant Origin
No full textThe article discusses the main trends in the illegal trafficking of plants containing psychoactive substances of the hallucinogen class. The author reveals the features of hallucinogens and dissociative anesthetics. The article also provides statistical indicators of the consumption growth of new psychoactive substances, including those contained in plant objects. The main criteria by which plant objects fall under the constructive apparatus of illegal trafficking are identified. The author pays special attention to applying specialized knowledge to expert identification and diagnostics of plants withdrawn from illicit trafficking containing narcotic drugs or psychotropic substances or their precursors. To counteract the illegal trafficking of narcotic plants, the author proposes measures to improve the operational algorithms of experts’ actions when investigating herbal narcotic drugs. On the example of plants species Banisteriopsis caapi, the author demonstrates the lack of the study of taxonomic units of tropical plants containing hallucinogens. To solve this problem, the author proposes to change the level of definition of taxonomic affiliation from species to generic in the List of Plants containing narcotic drugs or psychotropic substances or their precursors
