Supramolecular Alloys from Fluorinated Hybrid [4+6] Imine Cages
Authors: Kunde Tom , Pausch Tobias , Schmidt Bernd M.
Published: March 2021

To create innovative materials, efficient control and engineering of pore sizes and their characteristics, crystallinity and stability is required. Eight hybrid [4+6] imine cages with a tuneable degree of fluorination and one fully fluorinated [4+6] imine cage are investigated. Although the fluorinated and the non-fluorinated building blocks used herein differ vastly in reactivity, we are able to gain control over the outcome of the self-assembly process, by carefully controlling the feed ratio. This represents the first hybrid material based on fluorinated/hydrogenated porous organic cages (POCs). These alloys with unlimited miscibility in the solid state were obtained as highly crystalline samples after recrystallization and even showed retention of the crystal lattice. All alloys and the fully fluorinated [4+6] imine cage were analysed by MALDI-MS, SCXRD, PXRD and in regards to thermal stability (TGA).

Published: March 2021

Organic π-conjugated polymers are promising heterogeneous photocatalysts that involve photoredox or energy transfer processes. In such settings, the materials are usually applied in the form of a dispersion in liquid medium, which is bound to certain technological limits of applicability. Herein, we present an innovative approach using carbon nitride thin films prepared via chemical vapor deposition (CVD) at different vessel walls and using them as batch and microfluidic photoreactors. This approach allows not only to fabricate technologically relevant and reusable devices, also photophysical properties of carbon nitride, such as singlet-triplet energy gap and lifetime of triplet excited states, are improved, when the material is assembled in thin films. These morphological changes are employed to maximize performance of the materials in photocatalytic reactions, in which the carbon nitride thin films show at least one orders of magnitude higher activity per area unit compared to photocatalysis using suspended particles.

Published: March 2021

Dietary fibre is the name collectively given to the indigestible carbohydrates present in foods. These carbohydrates consist of cellulose, gum, pectin and mucilage. Enzymes of gastro-intestinal tracts in humans do not digest these fibres. Plants are the only source of dietary fibre. It is found in grains, vegetables and fruits. Dietary fibre helps to keep the digestive system healthy, and it is vital in reducing the risk of diseases such as coronary heart disease, diabetes, diverticulosis, haemorrhoids and intestinal cancer. Undigested fibres enter the large intestine where bacteria ferments them. Carbon dioxide, nitrogen, hydrogen and short-chain fatty acids are the by-products of the fermentation. Soluble fibre and resistant starch also serve as prebiotic and supports the necessary probiotic for digestive health. In grapes, peas, beans and barley, much of the soluble fibre is extracted. When dissolved in the water, a gel-like substance is formed. Soluble fibre helps to support the growth of friendly bacteria needed to maintain a healthy intestinal system. They also help in slowing down the time taken by the food to pass through the stomach into the small intestine, which helps to slow down the absorption of glucose and controls the blood sugar levels and helps in managing diabetes mellitus and keeps you feeling fuller for a longer time. The diets with high fibre intakes are known to have beneficial health effects as they have water holding capacity, helps in adsorption of organic molecules and facilitates its excretion, hypoglycemic effects and hypercholesterolemic effect. The inclusion of fibre rich food in weight-reducing diets is found to helpful since it provides a feeling of fullness without consumption of excess calories. The present review discusses the definition, nutritional properties of dietary fibre and therapeutic functions of dietary fibres in health and diseases.

Predicting Bank Defaults in Ukraine: A Macro-Micro Perspective
Authors: Hlazunov Anatolii , Verchenko Olesia
Published: March 2021

This paper develops an early warning model (EWM) for a micro-macro analysis of individual and aggregated bank vulnerabilities in Ukraine. We applied a stepwise logit for predicting defaults at Ukrainian banks based on a panel bank and macro-level data from Q1 2009 to Q3 2019. Next, we aggregated individual bank default probabilities to provide policymakers with information about the general state of the financial system with a particular focus on generating a signal for countercyclical capital buffer (CCB) activation. Our key findings suggest that the probability of default exceeding 11% could signal about a vulnerable state in a bank and, in the aggregated model, in a financial system in general. The aggregated model successfully issues an out-of-sample signal of a systemic crisis four periods ahead of the start of the 2014-2015 turmoil.

Published: March 2021

The objective – to presents the observation of combined treatment of a patient with arteriovenous malformation of the lower jaw.A man, 21 years old, was hospitalized in the Scientific-Practical Center of Endovascular Neuroradiology NAMS of Ukraine with complaints of bleeding from a tooth socket after an attempt to remove the 6th tooth (first painter) of the lower jaw on the left. According to the performed survey radiography of the lower jaw, an aneurysmal bone cyst was revealed in the body of the lower jaw on the left, corresponding to the localization of bleeding. According to cerebral angiography, an arteriovenous malformation of the lower jaw was revealed on the left, the afferent arteries of which were: the right facial artery (a branch of the right external carotid artery (ECA)), the left facial artery (a branch of the left ECA), the lower alveolar artery, the superior-posterior alveolar artery (branches of the maxillary artery ‒ the terminal branch of the left ECA) with drainage into a vein, which was located in the body of the lower jaw. In order to exclude the malformation from the bloodstream and prevent bleeding, a controlled embolization of the malformation was performed using non-spherical emboli – polyvinyl alcohol (PVA) particles from Cook, USA. Using a transfemoral approach, a guide catheter was inserted into the orifice of the ECA, then a Headway 27 microcatheter (Microvention, USA) was passed through it along a Traxes 14 guide wire (Microvention, USA), the afferent arteries of the malformation were selectively cathete-rized in turn, and embolization was performed after superselective angiography. The patient was discharged in a satisfactory condition. Two weeks after the operation, the bleeding resumed. The performed control cerebral angiography revealed a relapse of the malformation with a change in its angioarchitectonics ‒ the filling of the malformation in the late arterial and venous phases of cerebral blood flow was noted. Re-embolization was performed using PVA emboli (Cook), which was supplemented by transcutaneous puncture of the drainage vein in the mandible and its embolization with histoacryl (B. Braun, Germany) and lipiodol (Guerbet, France) in a 1 : 1 ratio. Results. As a result of using this technique, it was possible to turn off the malformation completely. For 6 months from the moment of surgery, no bleeding was noted, and subsequently the patient had a tooth removed without complications.Conclusions. The proposed method for treating arteriovenous malformation of the lower jaw, proposed in this case, showed the effectiveness of a combination of endovascular embolization in combination with transcutaneous embolization of the draining vein and can be successfully used to treat this pathology.

Published: March 2021

This work examines the most promising design solutions for the creation of propulsion systems for ultra-light launch vehicles by small private enterprises in the rocket and space industry. Comparison of the metal consumption of the combustion chambers with the energy characteristics at different operating pressures showed that the most optimal operating pressure is 12,16 MPa. Comparison of the relative and absolute values of the masses of various configurations describes the nature of the relationship between the number of combustion chambers and the total mass of the propulsion system. It was found that nine-chamber propulsion systems with cameras made with extensive use of additive technologies best meet the key requirements. The analysis carried out includes an assessment of the design parameters of both various components and assemblies and the propulsion system as a whole. Various layouts of propulsion systems are considered in detail, the required degree of technological complexity of structures of various units and assemblies, their production cost are estimated. The ratio of the obtained mass-energy characteristics was achieved through the implementation of design solutions that became available due to the use of additive technologies. The obtained results of preliminary calculations demonstrate the applicability and efficiency of design solutions considered for use in the propelled propulsion system for a promising launch vehicle.

Authors: Lu H. , Wang C. , Zabolotnov Yu. M.
Published: March 2021

The dynamic analysis and motion control of a spinning tether system for an interplanetary mission to Mars is considered. The space system consists of two spacecraft connected by a tether with thrusts to control its movement. The movements of the tether system in the sphere of action of the Earth, on the interplanetary trajectory and in the sphere of action of Mars are consistently analyzed. In near-Earth orbit, the transfer of the system into rotation with the help of jet engines installed on the end spacecrafts is considered. The spin of the system is used to create artificial gravity during the interplanetary flight. The tether system spins in the plane perpendicular to the plane of the orbital motion of the center of mass of the system. To describe spatial motion of the system, a mathematical model is used, in which the tether is represented as a set of material points with viscoelastic unilateral mechanical connections. When calculating the movement of the system, an approach based on the method of spheres of action is used. Spacecrafts are considered as material points. The level of gravity and spin of tether system is controlled by thrusters. The structure of the controller for controlling the angular speed of rotation of the tether system is proposed. The simulation results are presented to confirm the effectiveness of the proposed control algorithm, which provides a given level of artificial gravity for th e interplanetary mission under consideration.

Fuzzy Xbar and S Control Charts Based on Confidence Intervals
Authors: Pekin Alakoc Nilufer
Published: March 2021

There have been changes since the companies have realized the important role of quality improvement in their success. If they are able to produce high quality products and satisfy demands, then they can survive in competitive global markets. Quality improvement applications aim to decrease variability, which leads to less cost, production time, number of defects, scrap, rework and more customer satisfaction. Quality can be improved by reducing product variability. On the other hand, uncertainty or subjectivity is a part of many engineering and real life problems. However, these problems cannot be solved by traditional methods. This study focuses on constructing Xbar and S control charts in fuzzy environment. The approach is developed by considering the theoretical structure of the Shewhart control charts. The core of the approach depends on the combination of parametric interval estimation and fuzzy statistics. Control limits and samples are presented by fuzzy numbers which ensures to maintain fuzziness in control charts. An important property of the approach is that the fuzzy charts can be reduced to Shewhart control charts. A simulation study was conducted for the performance evaluation of fuzzy Xbar and S control charts. The proposed fuzzy control chart is sensitive to process mean shifts and variance changes, and outperforms the traditional control charts under the changes of variance. In addition, an example from the literature shows that the approach is an effective way of presenting fuzziness in the quality characteristics, which enables the approach to have high applicability to the real life problems.

Published: March 2021

The article is devoted to the study of the accounts of the Diary written by the Russian academician S. F. Oldenburg who was the head of the First Russian Turkestan expedition organized in East Turkistan in 1909-1910. S. F. Oldenburg’s records have not been studied enough, though they were used by few scholars earlier, one of them being N. V. Diakonova. The full text of the Diary was prepared to publication by М. D. Bukharin, the Corresponding Member of the Russian Academy of Sciences and the author of this article in 2018 in Moscow. Despite the fact that the goal of the First Russian Turkestan expedition was to study ancient archeological sites in East Turkistan and collect manuscripts in ancient languages of East Turkistan, members of the expedition recorded valuable information on modern time and everyday life of the local population, accounts on social and economic relations in the region. The article includes preliminary analysis of the accounts of the Diary of S. F. Oldenburg and describes it as a valuable source for the study of history and culture of the Uigurs and their historical homeland – East Turkistan. The article focuses mainly on materials of the scholar relating to customs, traditions of the Uigurs, sacred Muslim sites (mazars) and folk songs (qoshaq).
ON THE QUESTION OF THE ARCHITECTONICS OF HISTORICAL SHORT STORIES BY B. RINCHEN
Authors:   Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the Russian Academy of Sciences, Dashibalova Darima
Published: March 2021

In the article author attempts to analyze the historical short stories of the outstanding Mongolian scientist and writer Byambyn Rinchen from the point of view of architectonics (external composition) and revealing the ways of expressing the author’s position. On the example of the short stories “Courageous Anu”, “Fatal Letter”, “Hand of the Goddess”, “The Bunia Flyer” it was revealed that they are characterized by freedom of composition, which is combined with a certain subjectivity and dynamism of switching from one stylistic register to another. The final parts of the short stories can be called “epilogues” or “colophons” and commentaries, which is quite consistent with the stylistic traditions of medieval Mongolian literature, but in the XX century they acquire a new, “living” breath.

The article argues that the market economy specifics translates into shifting a focus towards a discrete industrial enterprise, since to withstand in competitive settings, business must adequately and timely respond to changes and challenges of the external environment. A modern industrial enterprise is facing a critical need to carry out integrated systemic analysis to meet market demands, enhance product innovations, trending products in particular as well as to attract qualified staff and constantly upgrade their professional skills and competences by implementing relevant strategies to build flexibility and proactive approaches to respond to socioeconomic changes. The study demonstrates that market demands and the new economic system challenges give rise to certain crisis phenomena that negatively affect the development of domestic industrial enterprises. The article seeks to explore a range of different interpretations to the economic concepts of adaptability, system, management and management system available from academic sources and offers the author's original definitions which laid the basis for a structural decomposition analysis of the content of such notion as "adaptive-oriented enterprise management system based on innovation" which is viewed as a well-organized set of a strong targeted unity of each of the system backbone elements that is able to effectively respond to changes in the internal and external environment through the implementation of creative and intellectual development trends based on the aggregation of the dominant tenets of the innovation theory driven by consolidated effects from active creative innovation. This fosters effective economic and noneconomic accelerated growth through enhanced management performance and achievement of tactical and strategic goals. The theoretical implications of the study by help of structural decomposition analysis contribute to better understanding of the concept of adaptive-oriented enterprise management system based on innovation which is a crucial element in the theoretical and methodological paradigm as well as a framework for developing a methodological toolkit to assess the feasibility and effectiveness of managing transformations of enterprises as integrated business and economic systems. It is concluded that theoretical provisions related to adaptive-oriented enterprise management system based on innovation should be complemented by setting their implementation goals, specifying their functions and outcomes, together with developing and adapting methodological approaches to perform analysis and evaluation. Addressing the above issues will be a step forward in the applied research taxonomy in the theory of economic systems management.

This study focuses on a wide range of issues related to the effects of integration process on the development of economic relations, in particular, in the road transport services market. Special emphasis is put on the critical role of integration in contributing to building circular technological supply chains, ensuring sales coordination and management, reducing unit costs and increasing labor productivity. It is argued that the outcome of integration translates into a cohesive economic mechanism which in addition to its integrated elements is characterized by the presence of a core coordination element. The article offers a definition to a public-private partnership phenomenon, identifies its advantages and disadvantages, explores the mechanisms of public-private partnership implementation as well as suggests a toolkit to optimize the partnership functioning for integrated structures. This is a pioneering study that provides a rationale for the need to use several public-private partnership patterns simultaneously together with developing a mechanism for carrying out public-private partnership which is proposed to be consolidated into the mechanism of integrated partnership viewed as the most preferable one to be implemented in the market of road transport services. It has been verified that the integrated partnership pattern provides an opportunity to develop competitive advantages of all its participants. The research findings have enabled to make the following generalizations: the existing partnerships differ in types of arrangements and institutional support; prior to making a decision to launch a specific integrated partnership project, the mechanism of its implementation should be envisaged; to enhance the efficiency of the integrated partnership project implementation, building relevant infrastructure facilities is paramount; the prospects for further integrated partnership project operation assume the utilization of a network mechanism of public-private partnership which best meets the needs and the specifics of the road transport services market.

La sátira en los Cuentos chinos de Abraham Valdelomar
Authors: Silva-Santisteban Ubilluz Ricardo
Published: March 2021

Abraham Valdelomar nació en Ica en 1888 y falleció trágicamente en Ayacucho en 1919, luego de una corta pero deslumbrante carrera literaria en la que acometió todos los géneros literarios. En Valdelomar se ha privilegiado al admirable cuentista que fue con detrimento del poeta, el ensayista y el dramaturgo en una obra vasta y desigual en que se destacan dos tonos nítidamente diferenciados: uno exotista y artificial y otro en que se respira y palpa el ambiente de su aldea natal. Se trata, pues, de dos facetas del mismo escritor que coexistieron a lo largo de su vida: la esteticista, que podemos asimilar al modernismo, y la moderna que podemos asimilar a la posmodernista. También pueden encontrarse en él otras uniones de contrarios como la trágica y la satí- rica, la dramática y la irónica, la madura y la pueril, la cándida y la engolado.

Las anomalías del uraco representan un bajo porcentaje de las patologías abdominales, no obstante, forman parte del diagnóstico diferencial del abdomen agudo por las complicaciones que puede tener. Aunque son de difícil diagnóstico debido a los síntomas inespecíficos, las imágenes diagnósticas son de gran utilidad para su identificación y caracterización. En pacientes con obesidad mórbida, la presentación del cuadro aumenta el riesgo de morbimortalidad. Por ende, en estos pacientes es necesario un control postoperatorio estricto para evaluar complicaciones secundarias a la resección del uraco. Dado los casos limitados en la literatura, se requieren estudios clínicos adicionales, para brindar un seguimiento adecuado, en aras de identificar complicaciones y el tratamiento precoz de estas.
