Authors: Petrovicova E. , Knight R. , Twardowski T.E. , Schadler L.S.
Published: May 2022

This paper evaluates the physical properties of nano-reinforced nylon 11/silicon oxide composite coatings produced using high-speed flame spraying as a function of the process technology and the composition. The coatings were created from nylon 11 powders with starting particle sizes of 30 and 60 micrometer and with 5 to 20% by volume of 9 nm reinforcing silicon oxide particles. Corrosion tests on aluminum and steel substrates showed that the metallic substrate is effectively protected and that the corrosion resistance does not change even if the coating is exposed to salt water for 100 hours.

Authors: Borisov Y. , Sviridova I. , Korzhyk V.
Published: May 2022

This paper describes investigation into the effect of the inorganic fillers on structural and physical-mechanical properties of polyethylene-based composite coatings produced by thermal spraying. A comparative analysis of the thermal spraying methods was carried out using spray polymers as an example. It was found that the powder particles made of aluminum and an Fe-B alloy, which were added to the polymeric materials, act as artificial crosslinking centers. This resulted in a decreasing grain size and an improvement in the physical and mechanical properties of the coatings. At low fill levels of the polymeric materials (up to 10% by volume), the degree of oxidation of the coating material decreased during spraying. Paper includes a German-language abstract.

Authors: Chen H.C. , Pfender E. , Dzur B. , Nutsch G.
Published: May 2022

DC plasma spraying has been widely recognized as a quick and economic way to produce all kinds of coatings (metals, alloys, and ceramics) for a variety of applications. There has been a growing interest in using radio frequency (RF) plasmas. Studies have been reported on characterization of plasma-sprayed coatings by TEM, including thermal barrier coatings, alumina coatings, and Ni-Al coatings. There are, however, no detailed studies reported on microstructural comparisons of coatings prepared by RF and DC plasma spraying. In this paper, XRD, SEM, TEM, polarizing OM, four-point bending fracture, and molten particle impact behavior are used to clarify microstructural differences between the RF- and DC-coatings. The results showed that the microstructures were much different for both cases, especially in the interfacial region between the coatings and the substrates.

Simulation of Particle Flattening and Solidification Under Plasma Spraying
Authors: Gromyko G. , Zajats G. , Kundas S. , Ilyuschenko A.
Published: May 2022

In this paper, the flattening and the simultaneous solidification of a liquid particle when it hits a solid surface are described mathematically and numerically simulated in cylindrical coordinates on the basis of the Navier-Stokes equations. The heat transfer in the particle and in the substrate is simulated by solving the 2-D heat conduction problem, whereby hydrodynamic processes in the melted particle as well as pressure forces are taken into account. The particle solidification is investigated using the one-dimensional Stefan problem, taking into account the contact heat conduction at the boundary between particle and substrate. For numerical calculations, computational algorithms were created on the basis of the difference method, which were implemented in the form of an applied program complex.

Versiegeln von thermisch gespritzten Schichten (Sealing of Thermally Sprayed Coats)
Authors: Wielage B. , Hofmann U. , Steinhäuser S.
Published: May 2022

In order to improve the properties profile of thermally sprayed coats (in particular, the corrosion resistance), the coats are, amongst other items, posttreated with organic and/or inorganic posttreatment media. The coat combinations used are Al2O3/TiO2 (87/12), APS-sprayed, and WC-Co (88/12), HVOF-sprayed. Commercially available sealants and two products from other areas of application were used for sealing purposes. The main contribution of the sealing agents to the anti-corrosion protection lies in the fact that they seal open, (inter)connected pores and/or cracks and thus prevent corrosive media from penetrating into the sprayed coat and from reaching the substrate. In this respect, the best results are achieved with sealing agents which form a dense film extending into the pores of the coat. The component underneath can be protected optimally by the combination of the sprayed coat and the sealing agents. Paper text in German.

Authors: Tahara H. , Shibata T. , Andoh Y. , Yasui T. , Kagaya Y. , Yoshikawa T.
Published: May 2022

The quasi-steady magneto-plasma-dynamic (MPD) arcjet generator is a promising plasma accelerator, which has a coaxial electrode structure similar to those of conventional plasma torches. The MPD arcjet generator utilizes principally electromagnetic acceleration of the interaction between the discharge current of kiloamperes and the azimuthal magnetic field induced by the discharge current, although the working gas is accelerated aerodynamically through a nozzle in a thermal arcjet generator. In this paper, ablation-type MPD arcjet generators are developed for ceramic coatings. Discharge voltages and ablation rates of ceramic materials are examined, and front velocities of ablated atoms of ceramic component are also estimated using a streak camera. The Vickers hardness of coating is measured. Their cross sections are observed with a scanning electron microscope, and their surfaces are analyzed by means of x-ray diffraction and x-ray photoelectron spectroscopy.

Published: May 2022

Ammonia and a mixture of nitrogen and hydrogen are used for material processing. Since these gases are chemically active, the processing efficiency is enhanced. This article describes a study to understand the physical properties of ammonia and a mixture of nitrogen and hydrogen plasmas inside and outside an arcjet generator. Spectroscopic measurement is made, and several plasma properties are determined from the data. The result shows that the H-atom electronic excitation temperature and the nitrogen rotational excitation temperature decreased from 7000-11000 K in the constrictor to about 4000 K and to 1000-1500 K, respectively, on the nozzle exit with mass flow rates of 0.1-0.2 g/s at input powers of 7-12 kW. However, the NH rotational excitation temperature did not show a significant axial decrease even in the downstream plume. Paper includes a German-language abstract.

Authors: Dussoubs B. , Vardelle A. , Mariaux G. , Fauchais P. , Themelis N.J.
Published: May 2022

This paper presents a simulation of the simultaneous spraying of a metal and a ceramic powder with different configurations for the injection of the powder into the plasma jet. The plasma jet and the behavior of the injected particles were modeled with a commercially available computational model of the dynamics of liquid bodies. The particles are modeled as discrete Lagrangian objects. Three series of numerical tests were carried out: simultaneous spraying of the powder in a three-dimensional plasma jet in a stable state; simulation of the 3-D plasma flow, assuming that it fluctuates at the same frequency as the arc voltage; and simulation of the effect of the current fluctuation on particle behavior. A pre-calculation with an analytical model made it possible to determine the suitable gas flow rate so that the "average" trajectories of the metal or ceramic powders coincide at the same point on the surface.

Rebel, G. (2018). Turgenev in Russian culture. Moscow, St. Petersburg: Nestor-Istoriya. (In Russ.)
Authors: Vinogradova E. V.
Published: May 2022

G. Rebel’s book contains a series of essays on Turgenev’s life and work. The first part focuses on the problem of the ideological novel in the oeuvre of Turgenev and Dostoevsky. The second part examines personal relationships between Turgenev, Dostoevsky, and L. Tolstoy, as well as Turgenev’s influence on Chekhov. The author proposes a hypothesis about personal (financial) circumstances behind Turgenev’s dispute with Dostoevsky over the novel Smoke [Dym], as well as the parody of Turgenev in The Possessed [Besy]. Yet Turgenev and Dostoevsky are both attracted to the ideological novel, a genre each of them worked to develop. The book offers a detailed description of the roles Turgenev, Tolstoy and Dostoevsky played in the 1880 Pushkin celebration. Even though the emphasis on Turgenev as the key and central character of the study is justified, his single figure sometimes overshadows the literary and cultural context of the period, as presented in the book.

Published: May 2022

O objetivo do trabalho foi estabelecer um protocolo de avaliação métrica da zona pelúcida e aplicar os valores métricos com a relação à viabilidade do oócito. Foram avaliados 32 oócitos coletados de abatedouro e classificados em atrésicos e não atrésicos. Os oócitos não atrésicos passaram primeiramente por avaliação morfológica e posteriormente por avaliação métrica pela qual foi possível realizar a mensuração em mm da corona radiata, zona pelúcida e diâmetro do antro. A partir dos resultados obtidos foi possível calcular a média dos valores mensurados. A corona radiata dos 10 oócitos apresentava leve degeneração com valores médios de 27,10 mm, a zona pelúcida apresentou-se intacta com uma média de 2,45 mm e o diâmetro do antro, que manteve valores quase constantes, apresentou média de 58,75 mm. Quanto à relação morfologia-média da corona radiata, pode-se observar que oócitos com graus morfológicos menores (I e II) apresentaram, em média, maior tamanho médio da corona radiata comparado com os oócitos de graus maiores (III e IV). Não houve relação da morfologia do oócito com a zona pelúcida. Quanto ao diâmetro do antro pode-se observar que o único oócito de grau IV apresentou o menor diâmetro de antro entre os oócitos analisados. A análise métrica pode estabelecer parâmetros de uma célula de boa qualidade e facilitar a escolha para procedimentos.

Authors: Yaqub Humaira , Ahsan Ansa , Iqbal Mubashir
Published: May 2022

The current study discusses the metafunctional diversity of nominalized thematic structures in Achebe’s (1958) English novel, Things Fall Apart and in its Urdu translation, Bikharti Duniya (Ullah, 1991). For statistical measurement, O'Donnell’s (2008) scheme of the UAM Corpus tool has been used to annotate the selected corpus. After annotation, some nominalized themes in English and Urdu have been screened to interpret their grammatical realization, functional significance, thematic progression (McCabe, 1999) and unmotivated displacements of nominalized themes. The results show that the grammatical realization of nominalized themes in English and Urdu varies due to the verbs marked with gender and numbers. Additionally, the English and the Urdu nominalized themes go parallel in theme markedness but the difference is observed when the thematic information units become rhematic information units.

Authors: Zahid Muhammad , Arif Muhammad , Riaz Humaira
Published: May 2022

There has always been a huge debate about the misrepresentation of Pakhtuns. Pakhtuns have always been depicted as barbaric, exotic and uncivilized. Such kind of depiction disenfranchised their actual image throughout the world. Such misrepresentation basically paralyzed the identity and image of the said community. The present study explores Saidian' Co-Optation'' (self-orientalism) as a concept, following the footsteps of colonizers and contributing to the cultural misrepresentation of Pakhtuns. The primary text for the research is The Wandering Falcon (2011) by Jamil Ahmad. Such sort of misrepresentation carries different meanings andserves multiple purposes for the colonizers. The uni-polar, stereotypical and generalized misrepresentation unquestionably clouded the image of Pakhtuns. The research method used for the analysis of the selected text is textual analysis. It argues that howthe said work is keeping the promises of the colonizers to misrepresent their own people. The present study also highlights that how Pakhtuns are still under colonial suppression and are misrepresented by their own people.

Content Analysis of Western Media Framing of Hagia Sophia Reconversion Decision
Authors: Arif Muhammad
Published: May 2022

The decision to change the status of Hagia Sophia from a museum to a mosque stirred up a massive controversy in the non-Islamic world, even to the extent as questioning the secular nature of the Turkish Republic. A Turkish court issued a ruling which ultimately led to the re conversion of Istanbul's Hagia Sophia, annulling a government ruling that dates back to 1934. This decision caused anxiety in the Western capitals, though it is important to explore how the media framed this entire story. This research investigates the portrayal of this decision in the Western media. The method of content analysis was used to analyze various new stories published on the websites of print and electronic media. The theoretical framework used is Framing Theory. The research concludes that western media framed this decision in an overwhelmingly negative light.
Використання ентропійних показників для вимірювання складності економічних систем

Published: May 2022

Останніми роками було використано кілька підходів для ідентифікації механізмів, що лежать в основі розвитку та функціонування складних систем. Особливо корисні результати було отримано при їх дослідженні методами теорії випадкових матриць, моно- та мультифрактального аналізу, теорії хаосу з реконструкцією траєкторії системи у фазовому просторі та визначення її параметрів, таких як кореляційна розмірність, спектр показників Ляпунова, рекурентні карти. Однак, застосування деяких із методів висуває вимоги до стаціонарності досліджуваних даних, потребує довгих часових рядів та комплексного обчислення кількох параметрів. Іншим підходом до розгляду питання вивчення особливостей складних систем є обчислення характеристик ентропії. Метою даної роботи є аналіз сучасних тенденцій використання ентропійних характеристик системи для вимірювання динамічних властивостей складних систем.

Прогнозирование временных рядов является чрезвычайно актуальной темой в исследовании финансово-экономических и других сложных систем. Рассматриваемая технология сложных цепей Маркова содержит в себе принципы практически всех современных методов прогнозирования, включая длинную и короткую память в регрессионные модели, добавляя элементы фракталов в непрерывные эконометрические модели, а также существенно дополняя современный нейросетевой подход. С помощью иерархий времен, методика позволяет прогнозировать временные ряды, максимально используя информацию, поданную в исходном ряде, позволяет учесть закономерности на всех частотных уровнях. Настоящая работа посвящена исследованию и применению новой технологии прогнозирования, использующей сложные цепи Маркова .
Застосування кількісного аналізу рекурентних діаграм для моделювання універсальних властивостей кризових явищ
Authors: Соловйов Володимир Миколайович , Щерба В. В.
Published: May 2022

Рекурентні діаграми (РД) і кількісний аналіз рекурентних діаграм (КАРД) являють собою методології чисельного аналізу сигналів і здатні працювати з нелінійними і нестаціонарними динамічними системами. Крім того вони добре відображають зміни станів динамічної системи. Показано, що РД і КАРД виявляють універсальність критичного режиму в індексах фондового ринку перед крахом. Досліджувались часові ряди довжиною 2000 днів, у яких посередині знаходилась криза. Аналіз проведено на щоденних цінах закриття для індексів Dow Jones і S&P 500 (відповідно, крахи 1 Жовтня 1929 року та 19 жовтня 1987 року). Крах ринку NASDAQ припадає на 17 квітня 2000 року.

Relativistic quantum econophysics – new paradigms in complex systems modelling
Authors: Saptsin Vladimir , Соловйов Володимир Миколайович
Published: May 2022

This work deals with the new, relativistic direction in quantum econophysics, within the bounds of which a change of the classical paradigms in mathematical modelling of socio-economic system is oﬀered. Classical physics proceeds from the hypothesis that immediate values of all the physical quantities, characterizing system’s state, exist and can be accurately measured in principle. Non-relativistic quantum mechanics does not reject the existence of the immediate values of the classical physical quantities, nevertheless not each of them can be simultaneously measured (the uncertainty principle). Relativistic quantum mechanics rejects the existence of the immediate values of any physical quantity in principle, and consequently the notion of the system state, including the notion of the wave function, which becomes rigorously nondeﬁnable. The task of this work consists in econophysical analysis of the conceptual fundamentals and mathematical apparatus of the classical physics, relativity theory, non-relativistic and relativistic quantum mechanics, subject to the historical, psychological and philosophical aspects and modern state of the socio-economic modeling problem. We have shown that actually and, virtually, a long time ago, new paradigms of modeling were accepted in the quantum theory, within the bounds of which the notion of the physical quantity operator becomes the primary fundamental conception(operator is a mathematical image of the procedure, the action), description of the system dynamics becomes discrete and approximate in its essence, prediction of the future, even in the rough, is actually impossible when setting aside the aftereﬀect i.e. the memory. In consideration of the analysis conducted in the work we suggest new paradigms of the economical-mathematical modeling.

Modem market economy of any country cannot successfully behave without the existence of the effective financial market. In the conditions of growing financial market, it is necessary to use modern risk-management methods, which take non-gaussian distributions into consideration. It is known, that financial and economic time series return’s distributions demonstrate so-called «heavy tails», which interrupts the modeling o f these processes with classical statistical methods. One o f the models, that is able to describe processes with «heavy tails», are the а -stable Levi processes. They can slightly simulate the dynamics of the asset prices, because it consists o f two components: the Brownian motion component and jump component. In the current work the usage of model parameters estimation procedure is proposed, which is based on the characteristic functions and is applied for the moving window for the purpose of financial-economic system’ s state monitoring.
