Authors: Ахмедзянова Мария Рашитовна , Кобелев Александр Викторович , Николаев Александр Петрович , Писарева Аза Валерьевна 
Published: December 2020

Клетки печени наиболее подвержены отрицательным последствиям, т.к. печень принимает активное участие в обменных процессах и в выведении из организма вредных и токсичных веществ. С появлением методов исследования, позволяющих изучать локальный кровоток в различных отделах печени, значительно увеличились возможности распознавания патологии. Реогепатография позволяет оценить функциональное состояние сосудов печени, их тонус, эластичность и кровенаполнение, объемную скорость кровотока и выявить застойные явления в венах. Целью данной статьи являлась разработка технического проекта по созданию прибора для неинвазивной оценки кровотока печени. Разработанный прибор оценивает кровоток печени по изменению ее удельного сопротивления. Метод оценки - электроимпедансная реогепатография. Данный метод позволяет регистрировать динамические изменения в импедансе ткани, вызванные изменениями кровотока печени в период сердечного цикла при пропускании через ткань электрического тока высокой частоты и малой амплитуды. Предложена оптимальная конструкция реографа, состоящего из системы электродов, источника тока, биоусилителя, системы сбора данных и блока питания. Электродная система состоит из 6 электродов (2 токовых и 4 измерительных). Портативный прибор позволяет измерять импеданс в диапазоне 0-250 Ом
Liver cells are most exposed to negative consequences, because the liver takes an active part in metabolic processes and in the removal of harmful and toxic substances from the body. With the introduction of research methods that allow the study of local blood flow in different parts of the liver, the ability to recognize pathology has increased significantly. Rheohepatography can assess the functional state of liver vessels, their tone, elasticity and blood flow, the volume rate of blood flow and to identify stagnation in the veins. The purpose of this article was to develop a technical project to create a device for non-invasive assessment of blood flow in the liver. The developed device evaluates blood flow of the liver by changing its resistivity. The method of evaluation is electroimpedance rheopathography. This method allows to register dynamic changes in tissue impedance caused by changes in blood flow of the liver during the cardiac cycle when passing through the tissue of high frequency and small amplitude electrical current. The optimal design of the rheograph, consisting of a system of electrodes, current source, bioamplifier, data acquisition system and power supply unit is proposed. The electrode system consists of 6 electrodes (2 current and 4 measurement electrodes). The portable device allows measuring impedance in the range of 0-250 Ohm
Problems of economic security and regions’ competitiveness in conditions of decentralization
Authors: Bilyk Rostyslav , Filipchuk Nataliya 
Published: December 2020

The paper characterizes the nature of public regional policy in terms of strengthening of competitiveness and economic security in conditions of decentralization reform. It reveals the problems of institutional background of administrative and territorial reform and shows the threats to economic security of territorial communities. Methodical approaches to organization of monitoring of regional competitiveness and economic security parameters are outlined. The paper argues that suggested estimation indicators can become the ground for assessment of competitiveness and economic security condition in the regions, for detecting of bottlenecks and weaknesses and for elimination of threats. Main threats to realization of competitive advantages and maintaining of economic security in Ukrainian territorial communities are presented and a set of measures to implement efficient regional policy of economy competitiveness increase and economic security maintenance in territorial communities is suggested. The paper provides evidence that reforming of regional development policy should secure: transition from a “single center” policy to consideration of multi-hierarchy interests of economic entities at regional level based on the principle of vertical and horizontal coordination of measures of regional development stimulation and regional security strengthening; complex regulating impact based on the use of hybrid tools and mechanisms of regional development and security stimulation. The paper confirms that the following should become the priorities of such policy in conditions of decentralization: optimization of territorial basics of public authority with distribution of competences of local executive authorities and local governments; improving of regions residents’ life quality, reducing of differentiation by human development index and forming of polycentric system of territorial development; implementation of interregional projects and programs of efficient use of local resources; introduction of criteria of “problem” territories’ assessment in regions as well as efficient mechanisms of public support of interregional integration. Special attention is paid to the fact a region’s economy competitiveness is largely determined not only by its ability to “win” in competition with similar economic systems of the country, but by participation in megaregional groupings as well.
Композити в сучасній англійській мові як складова семантичної конденсації лексики
Authors: Онищенко Ірина , Яновець Анжеліка 
Published: December 2020

У статті окреслено роль композитології – науки про складне слово, що розвивається на фоні автономізації словотворення й обумовлена становленням словотворення як самостійної галузі лінгвістичних досліджень. Доведено, що виникнення композитів – це не специфічний процес, обумовлений широким розповсюдженням в сучасній англійській мові словоскладання, а передусім один із проявів загального процесу семантичної конденсації лексики, що відбувається в багатьох мовах. Обґрунтовано, що ретельне вивчення продуктивних типів формування складних лексем допомагає виявити нові тенденції та закономірності у використанні наявних мовних засобів при формуванні новотворів, що являють собою активно діюче джерело збагачення словникового складу англійської мови на сучасному етапі її розвитку.

Dark Sirens to Resolve the Hubble–Lemaître Tension
Authors: Borhanian Ssohrab , Dhani Arnab , Gupta Anuradha , Arun K. G. , Sathyaprakash B. S. 
Published: December 2020

Abstract
The planned sensitivity upgrades to the LIGO and Virgo facilities could uniquely identify host galaxies of dark sirens—compact binary coalescences without any electromagnetic counterparts—within a redshift of z = 0.1. This is aided by the higher-order spherical harmonic modes present in the gravitational-wave signal, which also improve distance estimation. In conjunction, sensitivity upgrades and higher modes will facilitate an accurate, independent measurement of the host galaxy’s redshift in addition to the luminosity distance from the gravitational-wave observation to infer the Hubble–Lemaître constant H
0 to better than a few percent in 5 yr. A possible Voyager upgrade or third-generation facilities would further solidify the role of dark sirens for precision cosmology in the future.
Pulsational Pair-instability and the Mass Gap of Population III Black Holes: Effects of Overshooting
Authors: Umeda Hideyuki , Yoshida Takashi , Nagele Chris , Takahashi Koh 
Published: December 2020

Abstract
Since the discovery of GW190521, several proposals have been put forward to explain the formation of a black hole (BH) in the mass gap caused by (pulsational) pair-instability (PPI), M = 65–130 M
⊙. We calculate the mass ejection of Population III stars by the PPI process using a stellar evolution and hydrodynamical code. If a relatively small, but reasonable, value is adopted for the overshooting parameter, the stars do not become red supergiants during the PPI phase. We show that in this case most of the hydrogen envelope remains after the mass ejection by PPI. We find that the BH mass could be at most around 110 M
⊙ below the mass range of pair-instability supernovae.
Dynamical Modulation of Solar Flare Electron Acceleration due to Plasmoid-shock Interactions in the Looptop Region
Authors: Kong 孔 Xiangliang 祥良 , Guo 郭 Fan 帆 , Shen 沈 Chengcai 呈彩 , Chen 陈 Bin 彬 , Chen 陈 Yao 耀 , Giacalone Joe 
Published: December 2020

Abstract
A fast-mode shock can form in the front of reconnection outflows and has been suggested as a promising site for particle acceleration in solar flares. Recent developments in the study of magnetic reconnection have shown that numerous plasmoids can be produced in a large-scale current layer. Here we investigate the dynamical modulation of electron acceleration in the looptop region when plasmoids intermittently arrive at the shock by combining magnetohydrodynamics simulations with a particle kinetic model. As plasmoids interact with the shock, the looptop region exhibits various compressible structures that modulate the production of energetic electrons. The energetic electron population varies rapidly in both time and space. The number of 5–10 keV electrons correlates well with the compression area, while that of >50 keV electrons shows good correlation with the strong compression area but only moderate correlation with shock parameters. We further examine the impacts of the first plasmoid, which marks the transition from a quasi-steady shock front to a distorted and dynamical shock. The number of energetic electrons is reduced by ∼20% at 15–25 keV and nearly 40% for 25–50 keV, while the number of 5–10 keV electrons increases. In addition, the electron energy spectrum above 10 keV evolves softer with time. We also find that double or even multiple distinct sources can develop in the looptop region when the plasmoids move across the shock. Our simulations have strong implications to the interpretation of nonthermal looptop sources, as well as the commonly observed fast temporal variations in flare emissions, including the quasi-periodic pulsations.
Identification of Hot Plasma Anomalies in Solar Wind Using Fe Ion Charge Distributions
Authors: Goryaev Farid F. , Slemzin Vladimir , Rodkin Denis 
Published: December 2020

Abstract
A presence of high Fe charge states in the ionic charge state distributions of the solar wind (SW) plasma, commonly characterized by the mean charge Q
Fe, provides valuable information on heating processes in the SW sources. We study the relationship between the parameter Q
Fe and the charge state distributions of Fe ions using the Solar TErrestrial RElations Observatory/PLAsma and SupraThermal Ion Composition data on the beginning of the 24th Cycle (2010 January–2011 July). We find that the Fe charge state distributions related to SW with Q
Fe ≈ 8–10 have an uni-modal shape peaked around Fe8+–Fe9+. When the Q
Fe value increases, the distributions change: at first, the profile extends to higher charge states and then transforms into a bi-modal shape with a second maximum around Fe16+ and a minimum around Fe12+. We discuss possible reasons for such bi-modality through the example of the interplanetary coronal mass ejection (ICME) event on 2011 February 24–26, where it was related to the heating of an eruptive prominence. For such an analysis, it is informative to have a special measure of the fraction of highly charged ions for the Fe ion charge distribution in SW. In addition to Q
Fe, we introduce a parameter q12 equal to a fraction of Fe ions with charges Q ≥ 12 and show that this parameter can be applied for identifying both the large-scale hot plasma enhancements associated with ICMEs and small hot fragments of SW plasma, which may be associated with small-scale solar activity in various coronal structures.
At Least One in Six Galaxies Is Always Dead

Published: December 2020

Abstract
Via numerical experiments, we show that the ∼10%–20% passive fraction seen at z ≳ 3 is consistent with galaxy star formation histories being maximally correlated stochastic processes. If so, this fraction should reflect a time-independent baseline that holds at any epoch or mass regime where mean star formation rates are rising. Data at

Análise comparativa entre métodos de levantamento planialtimétrico para elaboração do plano diretor da comissão regional de obras em Belém - PA
Authors: Lima Gerson Oliveira , Caldeira Mayara Cobacho Ortega , Caldeira Carlos Rodrigo Tanajura 
Published: December 2020

No levantamento topográfico planialtimétrico, os meios mais difundidos de aquisição de dados são através da Estação Total e do posicionamento GNSS (Global Navigation Satellite System). Com a evolução tecnológica ocorrida na área de aquisição de dados planialtimétricos surge o VANT (Veículo Aéreo Não Tripulado), sobretudo pela redução do custo de equipamentos e a rapidez na obtenção dos dados, diante da topografia. Deste modo, o presente trabalho busca comparar os dados de levantamento planialtimétrico, cálculo de área, perímetro e vetorização das edificações geradas por dois métodos de aquisição de dados (topografia e aerofotogrametria por meio de VANT), utilizando as instalações da Comissão Regional de Obras do Exército Brasileiro localizado em Belém-PA. Cabe ressaltar, que os métodos utilizados alcançaram as precisões preconizadas, quais sejam, poligonal Classe II PAC (NBR 13133/1994) para a utilização da Estação Total e PEC (Precisão de Exatidão Cartográfica) classe A no caso da utilização do VANT. Os resultados apresentados na aquisição de dados utilizados na forma comparativa, evidencia que não existe uma técnica perfeita. Assim, pode-se utilizar um ou outro método para situações diferentes e apresentar as vantagens e desvantagens associadas em cada método para elaboração do plano diretor e mapeamento da área em questão.

Published: December 2020

Avrupa’da yükselen sağ popülist hareketlerin ortak noktalarından biri göçmen karşıtlığı olarak kendisini göstermektedir. İktidardaki ya da muhalefetteki popülist liderlerin özellikle seçim zamanlarında sıklıkla vurguladığı biz/onlar ayrımı ve ötekileştirme politikası, sağ popülist seçmeni ulusal kimliğini koruması yönünde politize etme amacı taşımaktadır.
Bu çalışmada öncelikle popülizm literatüründe popülizm kavramına yönelik yaklaşımlar incelenerek popülizmin ne olduğuna dair bir çerçeve ortaya çıkarılacak, daha sonra Avrupa’da yükselişe geçen sağ popülist partilere ve bunların örnek söylemlerine yer verilecektir. Son olarak, Avrupa’da göçmen karşıtlığıyla bilinen en popülist liderlerden biri olan Macaristan başbakanı Viktor Orban’ın göçmen karşıtı söylemleri ve göç politikaları incelenecektir.
Diccionario Biográfico de las Izquierdas Latinoamericanas. Movimientos Sociales y Corrientes Políticas
Authors: Jaramillo Restrepo Sandra 
Published: December 2020

El artículo revisita la producción de diccionarios biográficos del movimiento obrero y de izquierda en América Latina para analizar los principales elementos de su producción, contrastarlos entre sí y reconocer la tradición en la que se inscriben. Ellos constituyen un verdadero acumulado desde el cual posicionarse con firmeza para emprender el ambicioso desarrollo de un Diccionario Biográfico de las Izquierdas Latinoamericanas, el cual sostiene la pretensión de pensarnos como región latinoamericana y establecer puentes entre las disímiles experiencias nacionales. Y es justamente ese diccionario, y su perspectiva teórico-metodológica puesta ya en ejecución, la que aquí se presenta.
Como lo nombrara Francoise Dosse, estamos ante una “apuesta biográfica” más. Una que reivindica el género, el método y el recurso biográficos, sin dejar de atender a la advertencia de que su objeto privilegiado, el héroe de la historia, ha sido superado. Además, subyace el esfuerzo de conectarse con una época que retoma al sujeto, pero acusa recibo de la crítica estructuralista a la biografía. Realizado, necesaria y felizmente, a cientos de manos y “condenado” a la apertura e incompletud, el Diccionario Latinoamericano se abre camino entre fronteras diversas, com la relativa a los campos de especialidad. Y los estudios biográficos, los de las izquierdas y movimientos sociales y la historia intelectual son el trípode productivo que intenta habitar.

Published: December 2020

Este artigo relata a construção, a aplicação e a avaliação de uma proposta de ensino de ondulatória utilizando-se música, tendo como guia a teoria pedagógica de Paulo Freire. Durantes as atividades, procurou-se relacionar a música e em especial o instrumento musical violão, com os princípios e conceitos da física relacionados a ondas e a acústica. Desta forma, procurou-se através da música contextualizar o ensino com aspectos culturais do cotidiano dos alunos dentro de um contexto freiriano. Esta proposta é fruto das atividades do PIBID (Programa Institucional de Bolsas de Iniciação à Docência) do subprojeto da XXXXXXXXXXX do ano de 2019 e foi realizada em 5 encontros com duas turmas do segundo ano na Escola Estadual de Ensino Fundamental e Médio (EEEFM) XXXXXXXXXXX, no município de Vila Velha – ES. Os encontros foram realizados de forma dialogada sempre explorando os conhecimentos prévios dos alunos e priorizando os conceitos físicos. Ao final da intervenção, foi possível constatar que a abordagem conceitual, utilizando a música como tema, despertou considerável interesse dos alunos pela disciplina.
