Authors: Zakharova Natalia , Savinova Olga , Utelbayeva Akmaral
Published: October 2021

Propargylamines are a promising but quite poorly studied category of organic compounds. This work aimed to study the photochemical properties of propargylamines polymers containing porphyrin fragments with electron transfer reactions. The study was carried out in 2019 at the Institute of Organic Chemistry (RAS, Moscow, Russia). The obtained polymer was irradiated with a luminous source. The absorption spectra were studied by electron paramagnetic resonance using a radio spectrometer. The presence of porphyrin and propargylamine in the polymer solution has been established to promote the reaction of complexation. This is due to the presence of double bonds in the amino groups, whereas also porphyrin and bromanil, which is an electron acceptor. The resulting data allow explaining the processes involved in photochemical reactions during the irradiation of the porphyrin complex in the presence of bromanil. In the long-wavelength part of the spectrum (above 540 nm), electron phototransfer inside the polymer molecule to the porphyrin side and between molecules from the porphyrin anion radical to the neutral polymer molecule take place.

Authors: Abaza Bogdan Felician , Spanu Paulina , Jugravu Bogdan Alexandru , Apostol Dragos Alexandru
Published: October 2021

Recycling is a key process in any sustainable development strategy. This paper proposes solutions for the increasing waste collection rates by developing an educational model for developing innovative waste management solutions. The focus in this paper will be on making the correlation between experimental studies on compressive properties of recycling waste and designing a smart waste management compactor. Based on previous achievements on developing an innovative compactor system with selective waste collection, actual experimental trials will be analysed for generating compression patterns for different types of common waste containers which will be used in the conceptual design process of a compactor, impacting concept definition of all 3 subsystems: mechanical, electrical and software. A dedicated software module for compression parameters will be developed for importing experimental data trials and based on these to process and identify relevant compression parameters defining compression pattern for different common waste containers. These parameters will be used to assist the wok mode state machines for compacting wastes. This will improve compactor performance by optimization of compactor usage smart adaptability.

Published: October 2021

Polymethyl methacrylate (PMMA) is one of the common widely accepted biomaterials in prosthetic dentistry due to its acceptable advantages, since 1937. In the present work, PMMA reinforced with Al2O3 nanowires (Al2O3 NWs) and ZrO2 nanoparticles (ZrO2 NPs) were fabricated by a self-curing method. Mechanical and tribological tests were conducted to study the effect of nanofillers on the mechanical and tribological performance of PMMA nanocomposites. Compression and microhardness tests, as mechanical tests, were accomplished to estimate the elastic modulus and microhardness number of the present nanocomposites. Also, tribological properties of unfilled PMMA and its nanocomposites were realized by pin-on-disk tester under dry sliding conditions. Wear test was conducted at room temperature under applied loads of 10, 20, 30, 40, and 50 N at a constant sliding speed and distance of 1.256 m/s and 226 m, respectively to study wear rate and coefficient of friction (COF) of the nanocomposites. Experimental results revealed that the elastic modulus, microhardness, wear rate, and COF were enhanced with increasing nanofiller content up to 0.5 and 0.7 wt. % of Al2O3 NWs and ZrO2 NPs, respectively. Also, wear rate increased with increasing applied loads up to 50 N, while COF decreased with increasing applied loads up to 40 N. Finally, specimens� worn surfaces were examined and imaged using scanning electron microscope (SEM).
Cómo completar algunas de las piezas del Codex Calixtinus
Authors: Asensio Palacios Juan Carlos
Published: October 2021

Los manuscritos litúrgicos medievales con notación musical muy a menudo no copian todo aquello que debiera cantarse. Muchas fórmulas se presentan abreviadas, otras solamente citadas por su íncipit o su cadencia final y, a veces, aunque su escritura sea interválica, utilizan sistemas de notación que recuerdan a las primitivas notaciones in campo aperto, pero que son perfectamente interpretables a la luz de una tradición oral viva que nosotros podemos recuperar gracias a su escritura en otras fuentes. El Codex Calixtinus ejemplifica muchas de estas prácticas que aquí desarrollaremos junto a la presentación de una nueva transcripción del Dum Pater familias, uno de los cantos más emblemáticos de la paraliturgia jacobea.
Tras el rastro de tropos y prosas en el Codex Calixtinus
Authors: Tello Ruiz-Pérez Arturo
Published: October 2021

Todo el mundo conoce el Camino de Santiago y el Codex Calixtinus. Santiago de Compostela fue (y sigue siendo) uno de los más importantes centros de peregrinación de la Cristiandad, junto a Tierra Santa y Roma, durante toda la Edad Media y más allá. Por el mismo hecho de que tanto el Camino como el Codex hayan contribuido a la construcción de la idea de la peregrinación a la tumba de Santiago, merece la pena tratar estos dos temas de forma conjunta. En este contexto, los tropos y las prosas del Codex, como aquellos componentes de una parte más variable durante la celebración, serán tomados como indicadores y guías de la naturaleza de los intercambios culturales a nivel regional y de las transferencias locales mediante el canto.
Sobre este postulado, por tanto, el presente trabajo pretende incidir en los principales planteamientos y problemas que surgen cuando se debe afrontar el estudio de las migraciones en el canto durante la Edad Media, tomando como paradigma la prosa Gratulemur et laetemur contenida en el Codex Calixtinus. A través del análisis de variantes en su edición crítica y musical, adoptando algunas perspectivas de la stemmatica y de la historia de la recepción, esta prosa debe servir en términos metodológicos como muestra sobre la manera, el momento y algunas posibles influencias en la confección del Codex.

Authors: Gómez Murillo María Alejandra , Trujillo Navarrete Balter
Published: October 2021

Se sintetizaron nanovarillas de óxido de manganeso en fase cristalina beta (β-MnO2). Microscopía electrónica de barrido (SEM) y difracción de rayos-X (XRD) confirmaron la morfología y fase cristalina, respectivamente. Mediante la teoría del funcional de densidad (DFT), se calcularon las propiedades mecánicas teóricas de β-MnO2 con el programa CASTEP. Se realizó una optimización de la geometría de la celda unitaria, determinándose las constantes elásticas Cij, calculándose los valores del módulo de Young y de corte, y el coeficiente de Poisson, entre otros. Los resultados fueron comparados con los valores reportados en la literatura, encontrándose una significante similitud en los parámetros analizados. Las relaciones de Cij indicaron la aceptación de los criterios de Born, confirmando la estabilidad de la estructura cristalina de β-MnO2. La constante C44, así como el módulo de volumen y de corte, mostraron valores grandes, lo que indica un material con considerable dureza. Este comportamiento fue confirmado con el valor obtenido de la razón del módulo de volumen entre el módulo de corte por la aproximación de Hill. El entendimiento de las propiedades calculadas en este estudio usando CASTEP permitirá obtener parámetros adicionales de propiedades ópticas, termodinámicas, entre otras, así como el desarrollo de modelaciones y simulaciones que permitan entender y aplicar los conocimientos adquiridos a aplicaciones reales (experimentales), p. ej., en la remoción de contaminantes.

Published: October 2021

Рассматривается вопрос выбора расчетной сетки при моделировании пожара в тоннеле с помощью полевого метода и проводится оценка возможного влияния размеров ячеек сетки, а также граничного условия постоянства давления на результаты расчета. Выполнено моделирование пожара для четырех размеров расчетной сетки. Обоснована возможность применения наиболее грубой из используемых сеток с точки зрения инженерных расчетов, в том числе с оговоркой относительно постановки граничного условия.

The issue of fire safety of road tunnels is currently an urgent task. Road tunnels are usually not standard typical facilities, but the unique structures. Therefore, it is necessary to study the influence of various parameters on the development of fire in order to take into account the characteristics of a particular object and make decisions on its effective fire protection. Implementation of field tests in this case is expensive and time-consuming. In this regard, numerical modeling is one of the most effective methods of such research. Field models are the most common and currently used for numerical calculations. These models are based on the numerical solution of the system of conservation equations for small control volumes of the calculation grid. This paper examines the issues of selection the calculation grid when modeling a fire in tunnels using the field method is considered and the possible influence of the size of the grid cells is estimated. The mathematical model used in this work is based on a set of differential equations of hydrodynamics, heat transfer, as well as the equation of conservation of the masses of components. Four computational grids were selected for a horizontal (without slope) model tunnel to determine the optimal cell size. As a result of conducted calculations it was established the following: the size of calculated grid is not fundamental for the initial stage of the fire; the use of smaller grid may be preferable at further development of fire, accompanied by increase of combustion capacity to the maximum; the maximum temperature values, especially in the far sections, are obtained on the coarsest grid. The use of such a grid for estimated engineering calculations can be allowed.

Рассматривая инвестиционный аспект в срезе применения специальных системных режимов налогообложения (ССРН) субъектами малого предпринимательства (СМП) в регионах, необходимо отметить актуальность данной проблемы. Стратегическими задачами экономической политики страны является выравнивание уровней развития регионов России и выполнение национальных проектов в стране. Налоговый потенциал, являясь комплексным макроэкономическим потенциалом каждого субъекта федерации, содержит в себе не только показатели финансово-экономического развития, но и инвестиционную привлекательность. Системность специальных режимов налогообложения хозяйственной деятельности СМП играет свою финансовую роль как в формировании бюджетов регионов, так и инициируя инвестиционную привлекательность в субъект, имея в своем ресурсе преференциальную основу минимальных налоговых баз и ставок, упрощения процедур администрирования и налоговой отчетности. Предложена авторская множественная регрессионная модель, показывающая влияние применения малым бизнесом ССРН на инвестиционную привлекательность в регионе.

Considering the investment aspect in the context of the application of special systemic taxation regimes (SSTR) by small businesses (SMEs) in the regions, it is necessary to note the urgency of this problem. The strategic tasks of the country's economic policy are to level the levels of development of the regions of Russia and the implementation of national projects in the country. Tax potential, being the complex macroeconomic potential of each constituent entity of the Federation, contains not only indicators of financial and economic development, but also investment attractiveness. The systematic nature of special taxation regimes for the economic activities of the SMEs plays its financial role both in the formation of regional budgets and in initiating investment attractiveness in the subject, having in its resource a preferential basis of minimum tax bases and rates, simplification of administration procedures and tax reporting.

ABOUT TECHNOLOGICAL AND INSTITUTIONAL CIRCUMSTANCES OF MODERN FINANCIAL CRISES
Authors: Салахова Н.Ш.
Published: October 2021

Статья посвящена изучению условий возникновения финансовых пузырей и связанных с их крахом кризисов в условиях современной экономики. Внимание фокусируется на финансовых кризисах 2000 г. и 2008 г. в экономике США. Представлена точка зрения на финансовые пузыри, связывающая их возникновение с недальновидностью и подражательным поведением экономических агентов. Однако инвестиционное поведение и физических, и юридических лиц формируется под влиянием экономических институтов. В этой связи рассмотрены институциональные обстоятельства формирования финансовых кризисов. Существенным изъяном многих современных исследований таких кризисов является недостаточное внимание к связи институционального и технологического развития. Показана трактовка этой связи в работах Карлоты Перес, где кризисы 2000 и 2008 г. предстают последовательными звеньями одного процесса. Государственное регулирование инвестиционных процессов в условиях насыщения рынков новых технологий выделено в качестве основы противодействия такой кризисной связки. В пользу такого подхода свидетельствует опыт некоторых стран, сумевших избежать финансовых пузырей при преодолении нескольких технологических рубежей.

This article is devoted to the study of the conditions of financial bubbles emergence and the crises connected with their collapse in the modern economy. Attention is focused on the financial crises of 2000 and 2008 in the US economy. A point of view on financial bubbles, linking their occurrence with the short-sightedness and imitative behavior of economic agents is presented. However, the investment behavior of both individuals and legal entities is formed under the influence of economic institutions. In this regard, the institutional circumstances of the financial crises formation are considered. A significant flaw in many modern studies of such crises is the lack of attention to the relationship between institutional and technological development. The interpretation of this connection is shown in the works of Carlota Perez, where the crises of 2000 and 2008 appear as successive links of one process. State regulation of investment processes in the conditions of new technology markets saturation is highlighted as the basis for countering such a crisis link. The experience of some countries that have managed to avoid financial bubbles while overcoming several technological lines testifies in favor of this approach.

В данной статье предложен новый подход к имитационному моделированию ключевых бизнес-процессов в агент-ориентированных системах массового обслуживания для финансово-кредитных организаций. Особенностью предлагаемого подхода является применение гибридных методов агентного и дискретно-событийного имитационного моделирования, реализуемых в рамках интегрированной системы поддержки принятия решений. Подобная система может успешно применяться для поиска наилучших альтернатив при операционном управлении финансово-кредитной организации, в частности, при принятии решений о выдаче кредитов физическим лицам, открытии и закрытии депозитов и др. Разработана имитационная модель в AnyLogic и проведены оптимизационные эксперименты, подтверждающие эффективность предлагаемого подхода.

In this paper, a new approach to the simulation of key business processes in agent-based queuing systems (QS) for financial-credit organizations is proposed. A feature of the suggested approach is the use of hybrid methods of agent-based and discrete-event simulation, implemented within the framework of an integrated decision-making system (DMS). Such a system can be successfully used to seek the best trade-offs in operational management for financial and credit organization, in particular, when decision making on awarding loans to individuals, opening and closing deposit accounts, etc. The simulation model has been developed in the AnyLogic simulation tools. Optimization experiments were completed to confirm the effectiveness of the proposed approach.

The transformation of smart supply chains in the context of digitalization is at risk associated primarily with the coronavirus pandemic in 2020. Currently, supply chain management processes are gradually adapting to the pandemic. Traditional linear supply chains are being transformed into digital logistics networks. It is shown that, to a large extent, investments in the digitalization of their logistics activities and the introduction of smart supply chains lay the foundation for trends in the further development of logistics activities in the context of the digitalization of the economy.

We present detailed radio observations of the tidal disruption event (TDE) AT2019dsg, obtained with the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), and spanning 55–560 days post disruption. We find that the peak brightness of the radio emission increases until ∼200 days and subsequently begins to decrease steadily. Using a standard equipartition analysis, including the effects of synchrotron cooling as determined by the joint VLA–ALMA spectral energy distributions, we find that the outflow powering the radio emission is in roughly free expansion with a velocity of ≈0.07 c, while its kinetic energy increases by a factor of about 5 from 55 to 200 days and plateaus at ≈4.4 × 1048 erg thereafter. The ambient density traced by the outflow declines as radius ≈R
−1.7 on a scale of ≈(1–4) × 1016 cm (≈6300–25,000 R

s
), followed by a steeper decline to ≈7 × 1016 cm (≈44,000 R

s
). Allowing for a collimated geometry, we find that to reach even mildly relativistic velocities (Γ = 2) the outflow requires an opening angle of θ

j
≈ 2°, which is narrow even by the standards of gamma-ray burst jets; a truly relativistic outflow requires an unphysically narrow jet. The outflow velocity and kinetic energy in AT2019dsg are typical of previous non-relativistic TDEs, and comparable to those from type Ib/c supernovae, raising doubts about the claimed association with a high-energy neutrino event.
Further Evidence for Tidal Spin-up of Hot Jupiter Host Stars

For most hot Jupiters around main-sequence Sun-like stars, tidal torques are expected to transfer angular momentum from the planet’s orbit to the star’s rotation. The timescale for this process is difficult to calculate, leading to uncertainties in the history of orbital evolution of hot Jupiters. We present evidence for tidal spin-up by taking advantage of recent advances in planet detection and host-star characterization. We compared the projected rotation velocities and rotation periods of Sun-like stars with hot Jupiters and spectroscopically similar stars with (i) giant planets on wider orbits and (ii) lower-mass planets. The hot-Jupiter hosts tend to spin faster than the stars in either of the control samples. Reinforcing earlier studies, the results imply that hot Jupiters alter the spins of their host stars while they are on the main sequence, and that the ages of hot-Jupiter hosts cannot be reliably determined using gyrochronology.
Labour needs a real class analysis and it needs it now
Authors: Byrne David
Published: October 2021

In her book The New Working Class - How to Win Hearts, Minds and Votes, Head of Policy for the Labour Party Clare Ainsley has got class absolutely wrong. She seems to have no sense of the nature of post-industrial capitalism as a form of capitalism, including the role of finance and
property capital, and what that means for the way class is structured, understood and lived. If the Labour Party works to this view of class it will not be able to develop the necessary class base for a transformational politics. It needs a more in-depth analysis of the class implications
of post-industrial capitalism and of work experience within it; this would include, in particular, a recognition of the significance of households (as opposed to individuals) for incomes and wealth, especially in relation to home ownership and pensions, which have benefitted those in possession
of assets and had a major impact on generational inequality. It also needs to understand the experience not just of the poor but also of the 'squeezed middle', a group that - rather than being dismissed as embodying metro-cosmopolitan values (something that applies to only a very small fraction
of the middle class) - needs to be a key focus of political action.
Degrees on the side: student employment and the neoliberal university
Authors: Simpson Jessica
Published: October 2021

This article draws on interviews with 39 female students who work, in order to refute contradictory, and class-blind, narratives that see students as either workshy, or as 'failing' to prioritise their education over paid employment. The data reveals that dominant ideas of the undergraduate
experience are outmoded and fail to represent the multiplicity and complexity of students' lives. The experiences of the interviewees make it clear just how wide of the mark universities and governments are in their understanding of the employment pressures faced by many students. Rather than
being un/employed, young people are now engaging with university and work in 'new' ways, in response to the increased neoliberalisation of higher education and the labour markets. Participants ranged from students with side-jobs to students who were doing their degrees 'on the side'; either
as a strategic form of income generation and/or as a result of structural inequalities. The findings from the study add to scholarship demonstrating the need to rethink higher education and how it is delivered in the UK.

Background/Aims: Tuberculosis has incidence and mortality rates that are among the highest for all communicable diseases. Adverse drug reactions (ADRs) to anti-tubercular drugs are common, and have a major impact on treatment maintenance and prognosis. It is important to understand the characteristics of ADRs and establish a suitable management plan. Methods: We retrospectively reviewed patients with ADRs during treatment with first-line antitubercular drugs such as isoniazid, rifampicin, ethambutol, and pyrazinamide from 2009 to 2018. Age, sex, and total treatment period, and the onset, severity, seriousness, and system organ class of ADRs, were analyzed to understand the characteristics of first-line anti-tubercular drug-related ADRs. Results: A total of 1,606 of 5,482 patients (29.3%) experienced ADRs after administration of first-line anti-tubercular drugs. The incidence of ADRs related to isoniazid, rifampicin, ethambutol, and pyrazinamide was 22.2%, 21.3%, 24.5%, and 29.6%, respectively. A total of 2,098 ADR reports were made (mean of 1.3 ± 0.6 per patient). The rates of mild, moderate, and severe ADRs were 32.4%, 61.1%, and 6.5%, respectively. There were 127 reports (6.1%) of serious ADRs. Skin and appendage disorders were most frequently reported (27.5%), followed by gastrointestinal disorders (17.5%), and liver and biliary system disorders (13.1%). The total treatment period was longer in patients who experienced ADRs (224.0 ± 3.1 days vs. 247.0 ± 4.7 days, p = 0.009). Conclusions: The incidence of ADRs to first-line anti-tuberculosis drugs was 29.3%, and 6.5% were severe ADRS. ADRs prolonged the overall treatment duration, indicating the importance of their detection and management.
A Rare Case of Fibromuscular Dysplasia with Postpartum Renal Artery Rupture in a Non-Hypertensive Woman
Authors: Kim Eun-Eun , Won Yoodong , Kim Yeon-Hee , Shin Inhye , Kim Young Ok
Published: October 2021

Fibromuscular dysplasia (FMD) of the renal artery is a non-atherosclerotic, non-inflammatory vascular disease that causes stenosis, aneurysm, dissection, and occlusion of the vessel. We report a rare case of a postpartum FMD patient who presented with spontaneous acute perirenal hematoma due to renal artery aneurysm rupture after cesarean section. The 40-year-old patient presented with sudden onset of abdominal pain 2 days after an elective cesarean section performed at full gestational term. A computed tomography scan of the abdomen revealed perirenal hematomas with signs of FMD in both renal arteries. The bleeding was successfully controlled by transcatheter arterial embolization. Short-term continuous renal replacement therapy was performed until her renal function recovered. FMD of the renal artery is rare in pregnant patients. Additionally, aneurysm rupture can be life threatening and requires immediate medical attention and prompt management.
