This paper investigates the load frequency analysis (LFC) of two area interconnected realistic power system with multi-fuel generating units. Each area consists of thermal, hydro and gas power generating plants. A new evolutionary algorithm is proposed, named Hybrid artificial electric field (HAEFA) optimization algorithm and integral square error (ISE) performance index is utilized to find classical PI/PID controller gains. Later, total analysis is carried out in presence of PID an account of its superiority functioning rather than PI. Moreover, the efficacy of the presented algorithm is deliberated by testing on two area conventional power system model of thermal unit with structure of non-reheat turbines and also on sphere benchmark function. As the load variation is dynamic in nature, mitigating the area frequency fluctuations and tie-line power variations could not been fulfilled by primary regulator and secondary controller. Effective governing needs additional devices. Therefore, superconducting magnetic energy storage (SMES) devices are incorporated in both areas in addition to Thyristor controlled series capacitor (TCSC) is connected in tie-line. Results, shows the system performance has been significantly improved with SMES and TCSC in the presence of HAEFA based PID controller. The potency of the HAEFA algorithm is compared with other optimizations covered in literature.

Authors: Editorial Article
Published: January 2021

В октябре 2020 г. Союз педиатров России провел цикл научно-образовательных онлайн вебинаров «Образовательные дни в педиатрии». В связи с обеспокоенностью педиатров всего мира проблемой полипрагмазии и избыточного назначения детям антибиотиков, в том числе при лечении вирусных инфекций, стремительным ростом устойчивости микроорганизмов к антибактериальным препаратам, особенно во время пандемии COVID-19, отсутствием разработок новых противомикробных средств одной из особо актуальных стала тема «Доказательная фитомедицина и фармакотерапия в педиатрии», в рамках которой рассматривается применение натуральных лекарственных средств — фитопрепаратов, обладающих комплексным противовоспалительным и противоин фекционным действием, — как возможного альтернативного способа лечения и борьбы с нерациональной антибиотикотерапией для снижения роста антибиотикорезистентности. Необходимо подчеркнуть, что важнейшими условиями эффективного и безопасного применения таких лекарственных средств, как фитопрепараты, являются стандартизация лекарственного растительного сырья и совершенствование методов производственного контроля.

Authors: Schulze Adina , Mitterer Fabian , Pombo Joao P. , Schild Stefan
Published: January 2021

Notably, bacterial biofilm formation is increas-ingly recognized as a passive virulence factor facilitating many infectious disease processes. In this review we will focus on bacterial biofilms formed by human pathogens and highlight their relevance for diverse diseases. Along biofilm composition and regulation emphasis is laid on the intensively studied biofilms of Vibrio cholerae, Pseu-domonas aeruginosa and Staphylococcus spp., which are commonly used as biofilm model organisms and therefore contribute to our general understanding of bacterial bio-film (patho-)physiology. Finally, therapeutical interven-tion strategies targeting biofilms will be discussed.
A novel BR-SMAD is required for larval development in barber’s pole worm Haemonchus contortus
Authors: Li Fangfang , Qin Peixi , Ye Lisha , Gupta Nishith , Hu Min
Published: January 2021

SMAD proteins mediate TGF-β signaling and thereby regulate the metazoan development; however, they are poorly defined in Haemonchus contortus–a common blood-sucking parasitic nematode of small ruminants. Here, we characterized an R-SMAD family protein in H. contortus termed HcSMA2, which is closely related to Caenorhabditis elegans SMA2 (CeSMA2) involved in the bone morphogenetic protein (BMP) signaling. Hcsma2 is transcribed in all developmental stages of H. contortus but highly induced in the adult male worms. The RNA interference with Hcsma2 retarded the transition of infective L3 into L4 larvae. Besides, the bimolecular fluorescence complementation revealed the interaction of HcSMA2 with a TGF-β-activated-R-SMAD (HcDAF8). Together these results show a BMP-like receptor-regulated SMAD in H. contortus that is required for larval differentiation and underscore an adaptive functional repurposing of BMP-signaling in parasitic worms.

Behaviour of an interface between pavement layers obtained using Digital Image Correlation
Authors: Attia T. , Di Benedetto H. , Sauzéat C. , Pouget S.
Published: January 2021

To improve pavement design methods, the behaviour of the interfaces between pavement layers must be precisely taken into account. This paper describes the thermomechanical behaviour of an interface in the small strain domain. Thanks to the innovative 2T3C Hollow Cylinder Apparatus (2T3C HCA), the behaviour of an interface was observed directly with 3D Digital Image Correlation (3D DIC). The studied samples were constituted of two layers of bituminous mixtures with a bitumen emulsion at the interface. From cyclic tests performed at four different frequencies (from 0.01 to 0.3 Hz) and four different temperatures (from 10 to 40 °C), the complex interface stiffnesses in the tension–compression mode and in the shear mode were obtained. The time–temperature superposition principle was verified for the abovementioned stiffnesses. Knowing a 2S2P1D (2 Springs, 2 Parabolic elements, 1 Dashpot) model of the bitumen of the tack coat, the norms of the complex interface stiffnesses were modelled with 2S2P1D models by using a SHStS (Shift, Homothety, Shift and time Shift) transformation.
Effect of hybridization on the buckling behavior of perforated CFRP/BFRP laminates
Authors: Sajid Zubair , Karuppanan Saravanan , Azmi Mohd Asyraf Azim Bin Mohd
Published: January 2021

Structural instability, which is often referred to as buckling, is a major concern for the safe and reliable design of composite structures. Thin-walled composite structures are vulnerable to buckling. The problem is exacerbated when a hole in a thin-walled composite structure significantly reduces the buckling strength of the structure. Therefore, the objective of the current research is to reduce the significant drop in buckling strength due to the hole by hybridizing with a stiffer material. Basalt fiber reinforced plastics (BFRP) was used for the current research work because it exhibits mechanical properties comparable with those of glass fiber reinforced plastics (GFRP) but at a reduced price, making it a prospective substitute for GFRP. Experimental and numerical methods were employed to study the buckling behavior of seven different hybrid laminates. A strut buckling apparatus was used for the experimental work. Furthermore, non-linear buckling analysis in combination with eigenvalue buckling analysis was used to estimate the non-linear behavior of the composite. It was found that the hybridization of BFRP with carbon fiber reinforced plastics is effective in reducing the effect of a hole in the buckling strength reduction. Furthermore, the buckling resistance is influenced by the orientation of outer plies, the location of the stiffer material in the laminate and the location of less stiff material in the laminate.

Published: January 2021

Introducción: las migraciones humanas, especialmente cuando son forzadas e irregulares, pueden incrementar la violencia perpetrada hacia las mujeres. El actual fenómeno migratorio entre Colombia y Venezuela es una migración masiva, con una alta participación de mujeres, gran parte de ellas en condición irregular y vulnerabilidad socioeconómica a las violencias basadas en género (VBG). Este estudio describe las características de las mujeres gestantes migrantes venezolanas en las dos principales ciudades receptoras del Caribe colombiano (Barranquilla y Riohacha), así como también estima las prevalencias de VBG; finalmente, se identifican los principales factores socioeconómicos asociados.Metodología: estudio de corte trasversal con aplicación de un cuestionario cerrado estructurado a 836 gestantes migrantes irregulares que incluyó preguntas sobre violencias, así como sus determinantes socioeconómicos. Se ajustaron modelos de regresión logística para la presencia de cada forma de violencia. Resultados: la violencia psicológica (81,4 %), seguida de la violencia económica (35,3 %), fueron las más prevalentes. Por su parte, la violencia física tuvo una prevalencia de 14,5 % y la sexual de 2,2 %. En los modelos de regresión logística, se encontró una asociación estadísticamente significativa del bajo nivel educativo con la ocurrencia de violencia física, siendo mayor la fuerza de asociación con aquellas con un nivel educativo de primaria (OR: 5,51; IC95 %: 2,10-14,49), seguida de secundaria o técnica (OR: 3,18; IC95 %: 1,24-8,17).Conclusiones: estos resultados revelan la necesidad de incorporar al análisis de las migraciones y a las intervenciones en salud pública, una perspectiva de género que considere la mayor vulnerabilidad de las mujeres con bajo nivel educativo.

Published: January 2021

This paper addresses the experimental wireless MIMO channel modeling and validation based on channel sounding data using the approximation of the full channel correlation matrix. Measurement were carried out in indoor laboratory environment at central frequency 2.3 GHz. An analytical MIMO channel model is presented based on optimal approximation of channel covariance matrix. Approximation of a full channel covariance matrix is based on the optimal Kronecker product series expansion of the sample covariance matrix. The channel correlation matrices calculated from the measured channel coefficients were decomposed using Van Loan and Pitsanis approximation algorithm. Experimental validation of such model is presented. The accuracy of the MIMO channel modeling was evaluated by the correlation matrix distance and by calculating of CDF of channel capacity. The results show that these models have good agreement with the MIMO channel measured data. Also two popular analytical MIMO channel models – Kronecker and Weichselberger models are evaluated and compared with the presented channel model.
Antropología del sufrimiento social
Authors: Antón Hurtado Fina
Published: January 2021

El sufrimiento social no está causado exclusivamente por el dolor físico y su repercusión emocional, más bien se refiere a una expresión de la condición humana más extraordinaria, que es la base de la evolución cultural, y que consiste en que en los seres humanos, no hay acción sin intención, y esa intencionalidad se fundamenta en el conjunto de creencias, valores y normas que se forjan a través de la cultura, por tanto, el sufrimiento social se produce cuando hay un choque entre las creencias y los valores de la sociedad y las de las personas o la imposibilidad de aplicarlas. En este caso, es la tensión de la adaptación cultural la que induce la aparición de enfermedades, tanto físicas (enfermedades laborales), como psicológicas (depresión, estrés, ansiedad, etc.) tan frecuentes en las sociedades complejas y que responden a la carencia de sentido. La globalización económica coloniza no solo culturas sino, y sobre todo, los cuerpos y las mentes de las personas. La realidad virtual nos sitúa ante un espejismo de felicidad inexistente. Asistimos a un salto cognitivo-emotivo sin precedentes, cuya selección de las emociones que comunicamos a los demás, invisibiliza las que no son socialmente valoradas, pero no nos salva de sufrirlas. El individualismo imperante en las sociedades occidentales, encapsula el sufrimiento agravándolo y patologizando su gestión cultural. En esta contribución pretendo esbozar la presencia del sufrimiento social a lo largo del ciclo vital, a través de la mirada antropológica, rescatando, no sólo las palabras, sino también, los gestos, los sonidos y las emociones de nuestros informantes.

Authors: Pedroza Flores René
Published: January 2021

Las comunidades universitaria y escolar son objeto de ataques violentos que van desde la intimidación hasta el asesinato de estudiantes, padres de familia, maestros, directivos y demás personal involucrado en la educación. Atacar de forma violenta al sistema educativo es una práctica realizada por terroristas con el propósito de fortalecer su legitimidad y debilitar el poder del Estado: Secuestran, asesinan y destruyen instalaciones. Esta problemática es objeto de este artículo, se analizan los informes de la UNESCO y de Global Coalition to Protect Education from Attack (GCPEA) para conocer la evolución y expansión mundial de los ataques terroristas hacia las instituciones educativas durante el período de 2007-2019, mostrando las consecuencias de la violencia terrorista en el proceso educativo. Se establece como conclusión que existe una parálisis educativa en los países que padecen ataques terroristas porque se atenta contra el derecho de una educación digna y de calidad para todos. El artículo se divide en tres partes: En la primera parte, se abordan los actos de violencia y terrorismo que padecen la universidad y la educación en el contexto global; en la segunda parte, se muestra la evolución histórica de los ataques violentos y terroristas en el mundo; y en la tercera parte, se exponen los impactos del terrorismo en la universidad y en la educación.

Published: January 2021

Digitized Mandarin paediatric speech perception tests are limited in Malaysia for measuring outcomes among children fitted with amplification devices. Mandarin speech perception tests from other countries may not be suitable to be used in Malaysia due to regional vocabulary differences. This study aimed to develop digitized test materials to test Mandarin-speaking preschool children in Malaysia. This is a two-phased cross-sectional study where Mandarin words (n=113) were gathered with test item pictures developed and tested on 40 Mandarin-speaking children (aged 2;0 to 5;11 years old) with normal hearing in Study I. A total of 80 of 113 words with high familiarity among children were selected in Study I. In Study II, digital recordings of the words was conducted, followed by acoustic analysis, and sound quality evaluation. In total, 94 out of the 480 recorded word tokens were excluded in acoustic analysis. The remaining 386 tokens received good quality rating by three professionals. Validation of the recorded word tokens and pictures to select the final test items involved 20 Mandarin-speaking young adults in Study II. A total of 160 tokens were selected as final items and all pictures corresponding to these test items were validated as suitable representation of the test items. In conclusion, digitally recorded stimuli and pictures have been developed for a Mandarin speech perception test appropriate for Mandarin-speaking pre-school children in Malaysia. Ongoing research includes collecting normative data for the test and future research involves evaluating the test application in local audiology clinics.

Published: January 2021

Lip print is useful in forensic investigations for individual identification. The present study aimed to discriminate sex based on lip print patterns in Malaysian Malay population in Klang Valley using a scanning technique. Lip prints of 360 subjects (180 males and 180 females) were taken using the lipstick-cellophane tape technique, pasted onto A4 papers. These papers were then scanned using Brother DCP-J100 printer (300dpi resolution). The images were analysed using a software based on Suzuki and Tsuchihashi’s classification. The lip print images were divided into six sections which are upper left, upper middle, upper right, lower right, lower middle and lower left. The Pearson chi-square test showed that there are significant differences between sexes in each section except for the upper middle section. In males, type V (irregular pattern) was the dominant pattern for upper left, upper right, lower right and lower left sections (ranging from 71.1% to 86.7%) while type IV (reticular pattern) was dominant at upper and middle sections (ranging from 57.2% to 66.1%). Type IV (48.3%) was dominant in upper middle section for female, while for the rest of the sections, type V was the dominant lip print pattern (ranging from 40% to 82.8%). These results showed that sex discrimination between males and females in Malaysian Malay population, Klang Valley can be suggested for identification in forensic investigation.

Published: January 2021

Soil sample is one of the important evidence that can be found in crime scene. Unknown soil sample can be analysed and compared with reference sample in order to determine the origin as its physical and chemical components possess unique characteristics. The purpose of this study is to determine the physical and chemical characteristics of soil from oil palm plantations in Perak, Malaysia to assist forensic investigation. Total of 97 topsoil samples were collected from three different oil palm plantations in Perak. Particle size distribution was obtained using dry sieving technique and colour of soil sample was examined under three conditions that are dry, moist and ashed. Soil pH was measured using pH meter and percentage of composition of soil organic matter (SOM) was determined by weighing the sample before and after ignition. Result showed that the composition of particle size <0.18mm was within the range of 5.57-21.11% whereas for particle size between 0.18mm - 0.6mm was within 31.62 - 52.96% and 25.78-66.86% for particle size >0.6mm. The color mode of soil after oven dried, moistened and ashed was greyish brown (10YR 5/2), very dark greyish brown (10YR 3/2) and light yellowish brown (10YR 6/4) respectively. Soil pH was in the range of 5.79 – 6.70. The percentage of SOM was between 3.29 - 20.48%. The physical and chemical characteristics of soil analysed in this study from three different locations of oil palm plantations varied and it is possible to discriminate these locations based on the analysis highlighted in this study.

Published: January 2021

Chemical constituents and biological activities of the Mitrella kentii leaf oil were investigated in this study. Gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) were used to determine the chemical constituents of the oil. The oil was evaluated for its ability to inhibit prostaglandin E2 (PGE2) and thromboxane B2 (TXB2) productions in human whole blood using a radioimmunoassay technique. Its inhibitory effect on platelet-activating factor (PAF) receptor binding with rabbit platelets using 3H-PAF as a ligand and its free radical scavenging effect on DPPH were also investigated. Caryophyllene oxide (33.8%), E,Z-farnesol (6.9%), benzyl benzoate (6.5%) and viridiflorol (6.5%) were among the major components of the oil. Even though weak inhibitory activities were observed in both PGE2 and TXB2 assays, significant results were obtained in both PAF receptor binding inhibition and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging effect with IC50 value of 6.6 µg/mL and 155.6 µg/mL respectively. These promising activities warrant the development of the oil as an anti-inflammatory agent.
A Knot Not to Be Cut? The Legacy of Brexit over the CJEU
Authors: Simoncini Marta , Martinico Giuseppe
Published: January 2021

What was the role of the Court of Justice of the European Union (CJEU) in the Brexit saga? And what will the impact of Brexit be over the future structure and activity of the CJEU? This article deals with this twofold question and explores three different issues. Firstly, we will offer a reflection on the questions and the risks raised by the Wightman case, where the CJEU ruled on the unilateral revocation of the UK notification of its intention to withdraw from the European Union under Art. 50 Treaty of the EU. Secondly, we will analyse the impact of Brexit on the composition of the CJEU and, particularly, the risks for the independence of the Court raised by the advanced termination of the mandate of the British Advocate General. Thirdly, we will provide some insights on the scope of the jurisdiction of the CJEU in the post-Brexit Union, emphasising how the Withdrawal Agreement maintained its jurisdiction during and even beyond the transition period. This article reflects the events that took place up to 6 October 2020.
Lobbying Brexit Negotiations: Who Lobbies Michel Barnier?
Authors: Coen David , Katsaitis Alexander
Published: January 2021

Interest groups have a vital role in international negotiations and carry the potential to influence their outcome. This article contributes to discussions surrounding Brexit and institutional change in the EU, focusing on Article 50 negotiations and stakeholder engagement. Drawing from theories on deliberative democracy and institutional legitimacy, we argue that different groups are given access to the Chief Negotiator depending on the resources they can contribute. Assessing our expectations, we inspect the entire interest group population that held meetings with Michel Barnier and his team from 2016 onwards. On the aggregate, we observe a pluralist approach. A closer inspection reveals a tightly knit circle of insiders that hold unparalleled access. To the extent that these meetings offer a glance into the future of EU lobbying, European trade and professional associations are likely to observe growing cohesion and significance. Conversely, UK private interests will see their presence and influence diluted as their relevance grows smaller in Brussels. Following the trends we observe, think tanks and socioeconomic interests are likely to experience a continuous surge in their involvement in stakeholder activities.
Is the Grass Greener on the Other Side? Norwegians’ Assessments of Brexit
Authors: Fossum John Erik , Vigrestad Joachim
Published: January 2021

To what extent has Brexit affected Norwegians’ perceptions of their current relationship with the EU? What are the considerations that central political and societal actors bring up to explain their stances? What are the broader lessons for the EU’s relations with non-members? We argue that Norway’s EU affiliation is so close that we can draw on Catherine De Vries’ benchmark theory to assess whether Brexit affects Norwegians’ assessments of Norway’s relationship with the EU. We focus on the Norwegian government’s stance. Further, we consider opinion polls to understand the strength of domestic support for the EEA Agreement, and whether that support has changed as a consequence of Brexit. We thereafter look for political entrepreneurs or political change agents, in political parties, in interest groups, and among civil society activists. We find that Brexit has not served as a benchmark. It has not set in motion efforts to change Norway’s EU affiliation. Opponents diverge on alternatives, although share concerns about what they see as the EU’s neoliberal orientation. The analysis shows that we cannot assess Brexit as a benchmark without paying attention to the sheer size and magnitude of the EU–Norway power asymmetry.

Published: January 2021

A hipótese com a qual este dossiê trabalha é que desigualdades e violência são prismas produtivos para análises e temas fundamentais do debate urbano, conectando-nos diretamente às cidades e aos territórios. Nesse sentido, os artigos exploram a violência a partir de diferentes perspectivas que giram em torno dos conflitos urbanos decorrentes das práticas de roubo. Nosso objetivo é duplo: de um lado, procuramos refletir sobre práticas criminais contra o patrimônio a partir de suas especificidades, apreendidas em pesquisas qualitativas de caráter etnográfico centradas em interações e situações empíricas, mas sem perder de vista suas implicações sociológicas mais amplas. De outro, mais do que uma abordagem criminológica, interessam-nos as relações entre o fenômeno dos roubos e a questão urbana.
AN OVERVIEW AND FUTURE PROSPECTS OF CROATIAN GEOTECHNOLOGICAL HERITAGE
Authors: Briševac Zlatko , Maričić Ana , Brkić Vladislav , Bralić Vladi
Published: January 2021

Industrial heritage plays an important role in the economical, historical, and cultural identity of contemporary European society. A significant part of the industrial heritage consists of historical buildings which have remained after mining and petroleum exploitation. Moreover, industrial heritage can be also nurtured in countries in which mining and petroleum activities are not fully developed. It is inevitably associated with geological heritage. Furthermore, geological heritage is essential for a better understanding of nature, its wider appreciation and better protection. Mining has always played a significant industrial role, but it has recently lost its significance due to increasing environmental requirements regarding the European green deal and transforming the economy for a sustainable future. However, old mining and petroleum heritage sites can become attractions and they can contribute to the development of tourism and the community itself. A new term “geotechnological heritage”, presented in this paper, is related to mining, geological and petroleum heritage due to their significant interaction. This paper presents the used and unused touristic potential of heritage on selected sites in the Republic of Croatia. In addition, an analysis of the Croatian undervalued geotechnological heritage has been performed after the exploitation of stone and other nonmetallics, coal, metals, and petroleum. Unlike Croatia, the potential of geotechnological heritage has been recognized and exploited in most European countries. Therefore, Croatia has a great opportunity to develop heritage based on the experience of more successful members of the European Union.
HYDRAULIC FRACTURING DESIGN IMPROVEMENTS BY PROPPANT FLOWBACK MITIGATION METHOD APPLICATION DURING HYDROCARBON PRODUCTION
Authors: Jatykov Temirlan , Sagindykov Bimurat , Bimuratkyzy Kuralay
Published: January 2021

Proppant flowback after hydraulic fracturing treatment is quite a serious challenge that causes damage to both downhole and surface equipment, leading to unwanted workovers and production suspension, or other negative outcomes. Some special methods including preventive as well as corrective measures already exist in the industry to overcome the proppant flowback problems. However, there is no clear guidance on how to choose the method for certain conditions, particularly during the hydraulic fracturing design stages. Therefore, the authors conducted a comprehensive review of fourteen preventive technologies to systematize them and to propose an initial decision-making approach. The following methods were considered in this paper: Resin Coated Proppants (RCP), RCP with Activator, RCP with Nanoparticles, Proppant with Liquid Resin Systems (LRS), Proppant with Surface Modification Agents (SMA), Proppant with Proppant Consolidation Aid (PCA), Cylindrical Proppant, Microfibers, Thermoset Resin Fibers, Thermoset Film Strips, Deformable Isometric Particles (DIP), Expandable Proppants, Polymer Surface Modified Proppants, and In-situ Formulated Proppants. The review reveals physical, chemical, and technological properties of each method to select criteria for effective screening. So, the reader could find the appropriate proppant flowback mitigation method corresponding to a particular reservoir and the well conditions during the initial hydraulic fracturing design stages.
Fundamentos estructurales del verso libre en Taller de arquitectura, de José Agustín Goytisolo
Authors: Ayala Gallardo Francisco Javier
Published: January 2021

El presente artículo ahonda en el estudio del verso libre y, más en particular, de la silva libre impar, una de las formas de versolibrismo más características de la poesía española contemporánea. Se examinan los mecanismos métricos y rítmicos que intervienen en la con"guración estructural de Taller de arquitectura, de José Agustín Goytisolo, un texto formalmente unitario en el que el poeta proyecta su particular visión de la arquitectura y el urbanismo. En la silva libre, Goytisolo encuentra su mejor expresión de lo conversacional. Mediante el uso del encabalgamiento y la pausa, o de la rima como recurso expresivo, el poeta alcanza ese "no equilibrio entre tradición y modernidad que le permite lograr acercarse a lo narrativo sin tener que renunciar al componente rítmico del verso.

The complex tectonic setup of eastern Europe—resulting in strong spatial variations of the local seismic hazard—caused relevant institutions of neighboring countries to form a research cooperation to ease seismological research cooperations across borders.

Here, we briefly introduce the original and new Central and Eastern Europe Earthquake Research Network (CE3RN) parties, with a synthesis of the common results achieved so far and an indication of possible future developments. Since the formal establishment of CE3RN, several common projects have been initiated, such as the SeismoSAT Project for the seismic data center connection over satellite and the Historical and Recent Earthquakes in Italy and Austria Project, both funded by the European Union INTERREG Italy–Austria Program.

The most recent 22 March 2020 earthquake near Zagreb, resulting in considerable damage in the capital of Croatia, demonstrated the importance of fast data exchange, thus facilitating reliable analysis of the earthquake. In addition, a recent breakdown of data lines in Austria demonstrated the usefulness of alternative data transmission via satellite.

En este artículo se presenta una propuesta orientada a promover la modificación de los paradigmas del docente con el fin de descolonizar sus saberes y se refleje en su práctica pedagógica; la intención es que, durante las clases y espacios escolares, se le otorgue gran importancia al acervo cultural colombiano y se potencie la construcción de voz de los estudiantes. El componente metodológico se enmarca en la investigación acción participativa, se lleva a cabo una sistematización de la experiencia en el aula de primero de primaria de la Institución Educativa Oficial Técnica José Joaquín Casas, Chía, Cundinamarca, Colombia, por medio de la cual se identifica una problemática específica, se realiza una revisión documental y se triangula en el planteamiento de una secuencia didáctica, que otorga gran valor a las artesanías colombianas como componente cultural determinante en la descolonización de los saberes del docente. Los resultados del análisis permiten reconocer la importancia de emancipar los saberes del docente y así desarrollar prácticas de enseñanza significativas para sus estudiantes, en donde se reconozca la importancia del acervo ancestral, costumbres e ideologías propias de la cultura colombiana y se genere un espacio democrático, de libertad, seguridad y confianza donde los estudiantes construyan su voz a partir de las interacciones con sus compañeros, el docente y su entorno.
ENHANCING SCIENTIFIC SUPPORT FOR NATIONAL SECURITY POLICY MAKING: INTERNATIONAL EXPERIENCE
Authors: Alekseeva T. , Nazarov V. , Afinogenov D.
Published: January 2021

The article examines evolution of scholarly approaches towards the phenomenon of the “national security.” By the early 21st century this notion found its way in the official strategic documents of a wide range of states. The authors examine the Russian and international record of analysis in the field of national security, and assess the adequacy of existing views on this subject taking in the account emerging threats, risks and challenges, as well as the tasks of sustainable development of a country in the social, economic, political, information, spiritual and other areas. They start by presenting the early conceptualizations of this term in the debates of American experts in the 1950s and the 1960s. An important innovation of that period was disentanglement of the national security from purely territorial and military threat, by preparing for other types of contingencies. The article additionally examines the struggle between two alternative approaches towards protecting the national security in the United States: the one founded on unilateral domination and the other prioritizing collective actions. It demonstrates that the one important result of the Western debates was the emergence of a new field of study defined by policy relevant studies, which produce useful, original, and verifiable inferences, which are then injected in decision-making process. In order to promote a similar institutionalized expertise, the article suggests seceding the study of the national security in a separate discipline. This step will enable to further promote the training of specialists not only in the field of national security and strategic planning, but also political scientists and future specialists for the public service. The need for this is obviously related to the tasks of improving the quality of policy making and strategic planning in the Russian Federation, the implementation of national projects in an extremely complex international environment.

Published: January 2021

The aim of this research is to give a detailed description of local media working in Basque language, hence, providing a backdrop for other minority language local media. Our approach is to offer data based on a questionnaire distributed among 65 local media with a response rate of 84%, ten in-depth interviews and a focus group. The data revealed a total publication of 200.000 copies with potential for a 70 page newspaper, 400.000 readers, almost 300 employees and more than 1.000 collaborating individuals. However, in spite of seeking to collaborate within a common framework, diversity and economic insecurity limit the potential of these local media groups to do so.
Ethnic Identity Formation Among Basque-American Adolescents
Authors: Petrissans Catherine M.
Published: January 2021

This article focuses on the ethnic identity formation among one hundred Basque-American youth between the ages of nine and fifteen who were interviewed at the beginning and end of a two week long Udaleku held in Bakersfield California in 2013. This project explores four key questions related to the internal thought processes used by camp attendees to account for or try to make sense of their ethnicity. First, were camp attendees confident or confused about their ethnicity? Second, have participants attempted to “explore” their ethnicity and, if so how? Third, what does “being Basque” mean to camp participants and is their understanding primarily derived from the self or from significant others? And fourth, how do the above questions vary in terms of age, gender, family composition and club affiliation.
The Basques of New Orleans
Authors: San Sebastian Koldo
Published: January 2021

Basques have found their way to many corners of the world, and one of those is the distinctive city of New Orleans in the United States. The relationship of Basques with Louisiana antedates the independence of the United States, and, of course, incorporation of that territory into the American Union. The Basque presence was most evident throughout the nineteenth century and the first half of the twentieth, when a significant community of Basque mariners resided in New Orleans. This article provides a historical overview of the Basque connection to Louisiana, from the expulsion of the Acadians that sent Basques south, the arrival of Basque mariners, and those relocated Basques from Mexico. General immigrants found their way there as merchants, storekeepers, accountants and blacksmiths and in time a Basque District emerged. There was also a Basque religious presence. The article brings to light the Basque presence.
NUMERICAL ANALYSIS OF HEAT TRANSFER IN MULTILAYERED SKIN TISSUE EXPOSED TO 5G MOBILE COMMUNICATION FREQUENCIES
Authors: KAUR Jagbir
Published: January 2021

Rapid growth in wireless communications has triggered the advent of 5G mobile communication systems. The use of millimeter waves (30-300 GHz) in 5G system has generated global concern about its biological safety. In present paper, we have numerically analyzed the heat transfer in a 3D multilayered skin tissue exposed to 5G frequencies. The numerical scheme comprises coupling of solution of Maxwell's equation of wave propagation within tissue to Pennes’ bioheat equation. Temperature variations are analyzed at 28 GHz, 38 GHz, and 60 GHz. Additionally, electric field and specific absorption rate distribution are also studied. Highest values of electric field and specific absorption rateare estimated in epidermis layer of skin tissue. For all considered frequencies, highest transient temperature (37.36°C) is predicted in subcutaneous fat layer of the skin. However, the steady state temperature is nearly same as core body temperature (37°C). The results show that 5G mobile phones do not cause any thermal damage to the skin tissue and can be considered safe.
From Culture to People: Thinking Anthropologically with Jesus and Paul
Authors: Merz Johannes
Published: January 2021

The culture concept has been crucial to anthropology. Yet, I argue against its use. I examine how Jesus and Paul interacted with, and focused on, people and contend that we shift our attention from culture to people. Human diversity and difference should no longer be categorized into different cultures as relative, bounded and divisive units. Rather, we should view it as an integral part of humanity’s commonality. Shifting our attention to people as cultural beings also means a move beyond a preoccupation with knowledge by embracing practical, reflexive, and ontological engagements with others. It is only when we try to understand specific people’s diverse perspectives and the way they see themselves and the world, that we can take them seriously. This opens up anthropology, both at a theoretical level and by collaborating with other disciplines, including theology.

SCIENTIFIC APPROACHES TO STUDYING THE CYCLICITY OF INDUSTRIAL REGIONAL CYCLES
Authors: Semenychev V. K. , Khmeleva G. A.
Published: January 2021

The relevance of generalizing scientific approaches to studying the cyclicity of industrial regional cycles is associated with the insufficient studying of the appropriate methodological support and tools. The authors singled out normative, balance and evolutionary approaches as the main ones presented in the scientific literature on this topic. It is proposed to rely on the evolutionary approach and the paradigm of econophysics in the development of tools for the assessment and forecasting of industrial cycles, since they have high predictive potential.
