Authors: Saif Othman Aziz  , Ali Shawqi Saadoon
Published: April 2022

Blood loss is a common surgical complication, but patient complications and healthcare costscan be exacerbated by needless blood transfusions. Non-invasive and continuous monitoring ofhemoglobin concentrations is possible with the Radical-7 Pulse CO- Oximeter. These determinedvalues are identical to those obtained by blood sampling for hemoglobin concentrations, andthe technique enables continuous monitoring over time of changes in Hemoglobin levels. Aims ofStudy: to investigate whether noninvasive, continuous, and real-time monitoring of Hemoglobincould estimate the timing for further Hemoglobin measurements more accurately than clinicians’discretion during surgery. Patients and Methods: 54 Patients eligible for the study wereunderwent different surgeries with planned invasive venous blood gas sampling for bloodHemoglobin for hemoglobin measurement while Radical-7 Pulse CO-Oximeter continuouslyreading Hemoglobin noninvasively during each surgery. Blood samples were obtained 5 minafter induction of anesthesia (other samples was taken multiple time during operations accordingto time of operation). The Conventional venous blood gas measurements were compared with radical7 co-oximeter obtained at the time of the blood sampling. Results: In our study There was nostatistically significant differences (p>0.05) in mean hemoglobin level, whether measured by SpHbor by conventional laboratory. in addition, Bland–Altman plot was utilized and show no markeddifference between invasive and noninvasive method. All these factors signify a good compatibilitybetween the two methods. Conclusions: The radical 7 satisfactorily follows hemoglobin shifts andmore reliably predicts the required timing for early Hemoglobin management decisions throughoutsurgery.

In Silico Approaches for the Identification of Novel Inhibitors against Breast Cancer Up-Regulated Protein
Authors: Aloufi Bandar , Alshammari Ahmed
Published: April 2022

Breast cancer is a type of cancer that develops in the breast tissues. When some breast cells begin to grow abnormally, breast cancer develops. These cells grow and divide at a faster rate than healthy cells and continue to grow, generating a lump or mass. Cancer cells in the breast may spread to lymph nodes or other places of the body. The hormone estrogen encourages cancer growth when it binds to the receptor of the targeted protein. The purpose of this study is the rational screening of a 15,000 phytochemicals library against the estrogen receptor alpha protein. The library was employed for molecular docking to find the binding affinities and simulation analysis of the top-selected compounds. The top four compounds, Mangostenone E, Exiguaflavanone M, Sanggenon A, and Flaccidine were identified as direct inhibitors of estrogen receptors as evident from their high binding affinity and occupancy of specific binding sites. Mangostenone E was the leading phytochemical that showed a high docking score—15.97 (kcal/mol)—and bonding interaction at the active site of Mangostenone E. Leading phytochemicals were subjected to analysis for drug-like properties that further reinforced their validation. Potential molecules identified in this study can be considered lead drugs for the treatment of breast cancer.

A Sufficient Condition for the Global Convergence of Conjugate Gradient Methods for Solving Unconstrained Optimisation Problems
Authors: Yousif Osman , Abdelrahman Awad , Mohammed Mogtaba , Saleh Mohammed
Published: April 2022

Due to their remarkable convergence properties and performance in practice, conjugate gradient (CG) methods are widely used for solving unconstrained optimisation problems, especially those of large scale. From the 1950s until now, many studies have been carried out to propose new ones to improve existing CG methods. In this paper, we present a condition that guarantees the global convergence of CG methods when they are applied under the exact line search. At the same time, based on this condition, we did a minor modification on the CG methods of Polak-Rebiere-Polyak (PRP) and of Hestenes-Stiefel (HS) to propose new modified methods. Furthermore, to support the theoretical proof of the global convergence of the modified methods in practical computation, a numerical experiment based on comparing the proposed methods with other well-known CG methods was done. It has been found that the new modified methods have the fewest number of iterations and require the shortest time for solving the problems. In addition, they have the highest percentage of the test problems that solved successfully. Hence, we conclude that they can be used successfully for solving unconstrained optimisation problems.

The state and the church as regulators of pro-social behavior of Russians: an institutional analysis
Authors: Kislyakov Pavel A. , Shmeleva Elena A. , Sergeev Sergey E.
Published: April 2022

The issue of understanding socio-cultural challenges and threats to the state, society and the individual requires justification of socially approved, positive value-semantic grounds for maintaining the unity of Russian society. Political philosophy and social evolutionism show that the state and religion may act as institutional regulators of pro-social human behavior. The moral and doctrinal obligations acquired on the basis of religious identity play an important role in the formation of pro-social behavior. Modern research conducted by Western sociologists and social psychologists does not give a clear answer to the issue of the influence of the Christian faith on pro-sociality. Since the second half of 2012, Russia has been developing a new strategy for the development of society, building it on a traditionally conservative basis based on the cultural and Orthodox traditions of charity, mutual assistance and care. Orthodox faith and ecclesiasticism have an impact on the pro-social behavior of Russians. At the same time, our study showed that among Russians there is an ambivalent idea of a pro-socially oriented person in terms of religiosity and traditionalism. The development of ideas and practices of pro-social behavior, voluntary service to the needy finds a significant response in Christianity. The Russian Orthodox Church is rapidly developing both types of various diaconal practices of volunteering and their mass popularization, which indicates a qualitative modification of socio-cultural attitudes in the church and public space: there is a certain shift to institutional trends.
“Bread and house, shared alike…”: mythopoetic aspect of understanding friendship in K. Simonov`s poetry
Authors: Korzhova Inessa N.
Published: April 2022

The paper examines the poems of K. Simonov dedicated to the theme of friendship. They share high stability of semantics, leitmotif connections and speech embodiment. The strongest is the connection between the themes of friendship and death. It is not the community of views and similarity of characters, but the unity of trial by death, that constitutes the basis of comradeship. The act of dividing bread, less often beverage, is recurrent in the description of the life of friends. The stability of this component, its interpreting as an action that binds friendship, transfers it from the everyday plan to the ritual one and requires an appeal to the mythopoetic approach. The paper examines religious and folk variants of the rite of breaking bread and takes into account the reflection of this mythologeme in a Soviet poetry. We conclude that a poet does not reproduce any real rite, but uses a dominant in the folk consciousness connection of bread with a collective fate and lot. Friendship is conceived by Simonov as an introducing to a common destiny. This leads to the deindividualization of friends` image and the opposition of friendship to a personal category of love highlighted in a number of poems.
Evolution of folk art motifs in domestic printed textiles of the 40–60s of the 20th century
Authors: Morozova Ekaterina V. , Shcherbakova Аnzhela V.
Published: April 2022

The paper deals with design features of drawings using motifs of folk art at domestic enterprises producing printed textiles. Domestic textiles of the post-war years may be roughly divided into three periods. The patterns of the first post-war years and the beginning of the 1950s keep a stylistic unity with the pre-war period. Most of the drawings associated from our perspective with the image of the 60s were created in a rather short period of 1956–1965 and expressed themselves in bright rich ornaments. In the last four years, there has been a gradual evolution of textile patterns towards the organic plastics of Art Nouveau and “refinement” of forms, which create uniform filling of the fabric`s plane. The restoration of the textile industry began even before the end of the war. Since 1944, the unaffected enterprises resumed producing printed textiles for the population. In the first post-war years, drawings with the use of folk motifs most often represented an imitation of embroidery and weaving. The end of the 1950s and the beginning of the 1960s came to be a time of radical changes in a social and political life of the USSR. The artistic design of textiles comes under the influence of ideas of “international style”, the experimental search for unofficial art of the time, and international contacts. The motifs of folk art receive a figurative and emotional interpretation.
The work of a lifetime… The history of Song collection of Piotr Kireyevsky
Authors: Yudina Vera I.
Published: April 2022

Piotr Vasilievich Kireyevsky entered the history of culture as one of the founders of Russian folkloristics. The present paper is an attempt to provide a systematic analysis of the work of researcher` entire life — the Collection of Russian Folk Songs, which became the first monumental set of works of folk art in Russian culture. P. Kireyevsky's song collection is considered in the aspect of interaction of various factors — cultural, historical, socio-ideological, artistic and aesthetic. Much attention is paid to the cultural and historical context of appearance of this work, which summarized the efforts of progressive public of the first half of the 19th century: A. S. Pushkin stood at its origins, among “depositors” of the Collection were N. V. Gogol, V. I. Dahl, A. V. Koltsov, P. I. Yakushkin. The paper also touches upon the circumstances of Kireyevsky's turning to folk songwriting, determined by the combination of personal life experiences, ideological attitudes and Russian realities of the first half of the 19th century. The author traces the stages of Kireyevsky`s formation as a folklorist as well as the milestones of his collecting activities. The history of work on the collection of Russian folk songs is presented in accordance with the evolution of the scientist`s folkloristic views. The paper addresses the history of publications of the Song Collection, from its lifetime editions of the 19th century to our times (beginning of the 21st century) and dwells on the issue of establishing scientific methodology, relevant for various fields of modern ethnography.

Diagnosis and treatment of masses due to fungal infection of the central nervous system is often difficult. Radiologic features are often non-specific and are often confused with malignant lesions so that a new diagnosis can be made by histological examination after resection. The combination of medical and surgical treatment of fungal infections of the central nervous system is optimal in shortening the duration of antifungal therapy, providing a definitive diagnosis and improving patient outcome. A 57-year-old male patient was conscious with complaints of weakness in the left half of the body, progressive chronic headache for 6 months and seizures, with physical examination results in the form of papilledema dextra, paresis N VI dextra et sinistra, paresis N VII S supranuclear, hemiparesis flaccid of left with grade 2/3, chronic progressive cephalgia and with a history of partial seizures become secondary common. Non-reactive HIV, CT scan of the head supporting a primary brain tumor with suspicion of intratumoral bleeding and cerebral edema. After surgery, histopathological examination results suitable for cerebral abscess, leading to fungal infection that is Cryptococcus neoformans. The patient was treated with 600 milligrams of Fluconazole every 12 hours intraoral for 6 months, the complaints improved and the head MRI was evaluated as normal. Conclusions. Diagnosis of fungal infection is still a challenge. The combination of surgical medical therapy in a mass fungal infection of the central nervous system is optimal in shortening the duration of antifungal treatment, providing a definitive diagnosis, and improving patient outcomes.

Stroke is a leading cause of death and disability worldwide. The advent of acute reperfusion therapy, intravenous thrombolysis and endovascular thrombectomy, has revolutionized the field of stroke medicine, and neurology in general. Recent studies have implicated a major role of cerebral collaterals in the trajectory of acute ischemic stroke patients receiving reperfusion therapy. Collaterals sustain blood supply to the tissue in the setting of acute ischemia which prevents further expansion of the hypo perfused tissue, playing an important role in determining outcomes after acute ischemic stroke. The use of collateral assessment in routine practice in acute ischemic stroke, let alone in reperfusion therapy, is far from universal and limited. Future work in embedding collateral assessment in standards of care in acute stroke and management is warranted. This article provides a comprehensive update on the diagnostic and prognostic utility of collaterals in acute ischemic stroke and recommendations on collateral-based decision making in acute stroke and steps that can be taken for its rapid uptake in clinical practice.

Published: April 2022

The current research determines the most recent developments in natural fibres reinforced polylactic acid composites. Polylactic acid (PLA) is derived from renewable resources and is capable of degrading microorganisms, eliminating the pollution caused by petrochemical-based plastic. PLA is the most promising biodegradable material among biodegradable polymers since it is easily attacked by bacteria PLA decomposes easily, releasing H2O, CO2, and humus, the black material found in soil. PLA is a thermoplastic polymer that is widely used in the production of plastic bags, large planting cups, paper coating, fibres, films, packaging, and as a matrix material in composites. This review also discussed the physical and mechanical properties of several natural fibre reinforced polylactic acid composites. Several natural fibres have been used to reinforce PLA as a reinforcement for natural fibre composites in the field of composite manufacturing.

Published: April 2022

Chitosan nanoparticles can be used in many types of applications such as food packaging, cosmetics and biomedical field. Chitosan can be modified to form chitosan-based hydrogels for antiviral purpose. Chitosan-based hydrogels are commonly used in wound healing, tissue engineering and drug delivery. This study explains about the properties and the applications of chitosan-based hydrogels since there were not much paper or research about chitosan-based hydrogels used as antiviral agent. Usually, many researchers did some studies about antiviral application focusing only on chitosan itself but not specifically into chitosan-based hydrogels. The properties of chitosan are also not well explained in some research. The purpose of this study is to investigate the antiviral application of chitosan-based hydrogels based on chitosan properties.

Published: April 2022

This research is being driven by environmental legislation that requires the consumption and usage of environmentally friendly products. The focus of this research is to develop and characterize thermoplastic arrowroot starch (TPAS) based biocomposite films incorporating arrowroot fibre (AF) at various compositions (0–10 wt.%) using the solution casting method. The biodegradation behaviour of newly developed composite films was examined. The average degradation rates of TPAS and TPAS/AF–10 films were 8 and 9.84%/day, respectively. The soil burial results revealed that the weight loss of TPAS/AF biocomposite films was higher compared to TPAS film. The biocomposite films revealed arrowroot fibre, a novel waste resource that is both eco-friendly and simple to produce. Overall, incorporating arrowroot fibre with TPAS film improves biodegradability, making them more suitable for environmentally friendly food packaging.

Authors: Y M Vijaya Kumar , B S Seema , R L Natraj , L Yashaswini
Published: April 2022

The global gas emission is keeping on increasing for which cement industry alone contributes 5%. The enormous water is required for curing of concrete in construction industry which can effectively be used for various purposes. The accelerated carbonation curing shows a way to reduce these emissions in a very effective way by sequestering it in concrete elements. In this paper the effect of accelerated carbonation curing was reviewed on non-reinforced concrete elements (cubes) and reinforced concrete elements (prisms). The CO2 curing showed 60% in strength of cubes and prisms, respectively when compared to water cured specimens. This early age strength through waste gas proves beneficial in terms of reducing in atmospheric pollution and saving the water which is a critical resource now-a-days.
An Experimental Study on Curing of Mortar Cubes by Carbon Dioxide
Authors: B S Seema , Kumar Y M Vijaya , L Yashaswini , R L Natraj
Published: April 2022

Carbon dioxide (CO2) is the predominant greenhouse gas resulting from human industrial Activities. A significant fraction of CO2 discharged into the atmosphere comes from Industry point sources. Cement production alone contributes approximately 5% of global CO2 emissions. This emitted carbon dioxide, however, can be partially recycled into mortar through early age curing to form thermodynamically stable calcium carbonates. The carbonation reaction between carbon dioxide and appropriate calcium Compounds results in permanent fixation of the carbon dioxide in a thermodynamically stable calcium carbonate. Carbon dioxide and water can be found in almost every environment and thus all concretes will be subjected to carbonation. The experimental study on water cured and CO2 specimens for compression strength were carried out. The results show that mortar cubes has achieved increasing value as comparing with water curing.
Iron-60 in the Early Solar System Revisited: Insights from In Situ Isotope Analysis of Chondritic Troilite
Authors: Kodolányi János , Hoppe Peter , Vollmer Christian , Berndt Jasper , Müller Maren
Published: April 2022

We measured the nickel isotope composition of troilites from chondritic meteorites using the NanoSIMS to put constraints on the abundance of iron-60 in the early solar system. The troilites were selected from petrologic type 3 ordinary and carbonaceous chondrites. Based on petrographic observations and mineral chemistry, the troilites targeted for isotope analysis crystallized from melts, most likely in a nebular setting. Our isotope analyses did not reveal any significant correlation between nickel-60 enrichments and Fe/Ni ratios, either in the entire set of troilite grains or in individual troilites. The average inferred initial 60Fe/56Fe ratio of the studied troilites (i.e., the 60Fe/56Fe ratio calculated for the entire troilite population) is 1.05 (±1.48) ×10−8. This value is very similar to those estimated in the past for Semarkona chondrules, angrites, as well as diogenites and eucrites, based on the isotope analyses of bulk samples (10−9–10−8), but about two orders of magnitude smaller than the average initial 60Fe/56Fe ratios inferred previously for Semarkona troilites and many chondrules from ordinary and carbonaceous chondrites (10−7–10−6) using in situ analysis techniques. Based on petrographic evidence, and the generally unequilibrated nature of our samples, as well as on the timing of chondrule formation and planetary evolution, the lack of discernible signs of in situ iron-60 decay in the studied troilites is probably unrelated to metamorphic re-equilibration, and it is also not the result of a late formation of the troilites. We suggest that the highest inferred initial 60Fe/56Fe ratios reported in the literature are probably inaccurate.
Coronal Seismology Using Damping of Propagating Kink Waves
Authors: Pascoe D. J. , Van Doorsselaere T. , De Moortel I.
Published: April 2022

We consider the use of propagating kink waves, such as those observed by the Coronal Multi-channel Polarimeter, as a diagnostic technique. The transverse structuring of the plasma may be inferred by the frequency-dependent wave damping, which is attributed to resonant absorption. We include the effect of reflection of waves at the loop footpoints, which leads to the asymmetry parameter, describing the ratio of driven wave power at the footpoints becoming weakly constrained. The classical model of resonant absorption based on an exponential damping profile significantly overestimates the damping rate in coronal loops with low density contrast ratios. The use of the exponential profile in an analysis of observations therefore leads to underestimates for the density contrast ratio and associated parameters such as the heating rate following phase mixing.
Variations of the Plasma Environment Revealed by the Evolution of the Supra-arcade Fan in the 2017 September 10 Flare

Published: April 2022

Based on observations from the Interface Region Imaging Spectrograph and Hinode, we analyze the thermodynamic evolution of the supra-arcade fan (SAF) in the 2017 September 10 flare. The SAF presents discontinuous characters during the rising process, indicating a nonuniform process of magnetic reconnection in the solar eruption. The intensity peaks of the high-temperature spectral lines (Fe xxi 1354.08 Å, Fe xxiii 263.76 Å, and Fe xxiv 255.10 Å) basically correspond to the valley of the Doppler velocity and Doppler width. The temperature and density increase spatially at the upper boundary of the SAF. These results indicate that a compressed interface may exist in the SAF, where the plasma environment shows remarkable changes in density, temperature, and turbulence. In view of the fact that the height of the SAF is close to the hard X-ray source, we conclude that the interface could be related to termination shocks (TSs), taking into account the synthetic spectral profiles obtained from numerical experiments. In turn, the variations of the spectral profiles might be useful tools for identifying TSs from EUV spectral observations.

This paper explores the long-term stability of six Neptunian Trojans. In contrast with other Neptunian Trojans, these objects have previously unknown lifetimes and larger orbital uncertainties due to their shorter observational arcs. We obtained new astrometry of the six Trojans using the Magellan telescope, refit their orbits, and performed Gyr-long numerical integrations to estimate their lifetimes. The results show that five of these six objects are stable over Gyr timescales. The remaining object, 2015 VV165, has a calculated lifetime of 0.691 ± 0.001 Gyr, which is similar to the previous estimate of 0.65 Gyr. As a result, the shorter lifetime of this latter object is most likely physical (rather than due to uncertainties in its orbital determination).
Bubble mediated polymerization of RNA and DNA
Authors: Marks Roman
Published: April 2022

Research dedicated to trace rotational motion of bubbles in saline water revealed that these may generate either single cationic or cationic/anionic motions, including spliced double helix flow. In all cases, the aggregated ionic flows propagate in spiraling as well as rotational manner. However, if bi-ionic or double helix motion is generated, the flow is oppositely directed and has opposite electric charges. Next, the assembled flow is forced to pirouette within the bubble vortex. During that processing the narrowing of spiraling flow takes place and result in increase of revolutions to even millions per second. As a result, a significant friction is induced between revolving ionic hydrates allowing continuous detachment of electrons from covalent atomic shells of electropositive elements. Then, free electrons may be attracted by electronegative elements that are dissolved in seawater. Afterwards, that negatively charged elements may undergo electrical condensation around cationic centers of revolutions. That explain a unique mechanism which operates when negatively charged phosphate compounds and pentagonal blocks found in RNA and DNA as ribose as well as pentagonal rings in nitrogenous bases A and G are being winded. The compensative anionic flow and revolutions may conduct winding of hexagonal blocks found in nitrogenous bases A, G and C, T or U. These assume to gather more positive charge needed to bridge negatively charged sugar molecules in nucleic acids. Thus, the continuity in generation of electronegative compounds and spiral manner of arranging them within the sub-bubble vortices should be regarded as a mechanism responsible for precise, rotational-electric polymerization of elongated macromolecules of RNA/DNA architecture. Reported research refers mainly to physical processes activated by rising bubbles thus should be confronted with other experimental methods used in genetics, microbiology and chemistry.

Generalized perimantanes diamondoid structure and their edge-based metric dimensions
Authors: Ahmad Al-Nashri Al-Hossain , Ahmad Ali
Published: April 2022

Due to its superlative physical qualities and its beauty, the diamond is a renowned structure. While the green-colored perimantanes diamondoid is one of a higher diamond structure. Motivated by the structure's applications and usage, we look into the edge-based metric parameters of this structure. In this draft, we have discussed edge metric dimension and their generalizations for the generalized perimantanes diamondoid structure and proved that each parameter depends on the copies of original or base perimantanes diamondoid structure and changes with the parameter $ {\lambda} $ or its number of copies.
Two-dimensional pseudo-steady supersonic flow around a sharp corner for the generalized Chaplygin gas
Authors: Yao Aidi
Published: April 2022

In this paper, the expansion problem which arises in a two-dimensional (2D) isentropic pseudo-steady supersonic flow expanding into vacuum around a sharp corner for the generalized Chaplygin gas is studied. This expanding problem catches the interaction of an incomplete centered simple wave with a backward planar rarefaction wave and the interaction of a non-planar simple wave with a rigid wall boundary of the 2D self-similar Euler equations. Using the methods of characteristic decompositions and invariant regions, we get the hyperbolicity in the wave interaction domains and prior $ C^{1} $ estimates of solutions to the two interaction problems. It follows the global existence of the solution up to infinity of the gas expansion problem.
Una visión del papel territorial de la oferta de transporte público de pasajeros por carretera en la comunidad Autónoma andaluza. Fundamentos para su reforma.
Authors: López Lara Enrique
Published: April 2022

Se exponen en este artículo la metodología y las conclusiones a que han dado pie la elaboración de las «Directrices para la ordenación de los servicios de transporte público de viajeros por carretera en la Comunidad Autónoma de Andalucía». Se trata de un análisis de la actual estructura territorial y empresarial de la oferta de transporte público de pasajeros por carretera en Andalucía, diagnosticando su nivel de adecuación al nuevo modelo de descentralización que señala el Sistema de Ciudades de Andalucía. Se concluye con el apunte de la necesidad de aprovechar las potenciales ventajas que la Ley de Ordenación de los Transportes Terrestres (1987) ofrece -posibilidad de planificar y gestionar el sector priorizando criterios de rentabilidad social sobre los de rentabilidad económica-, en función de lograr un mayor equilibrio tanto socio-territorial como económico-funcional.

Las redes de teleflujos y su estructuración territorial en España: Los flujos telefónicos.
Authors: Seguí Pons Joana María , Picornell Bauza Climent , Petrus Bey Joana María
Published: April 2022

El objetivo fundamental del trabajo es analizar la configuración del territorio español en grandes áreas a partir de la interacción espacial de los flujos telefónicos. Las redes que se articulan a partir de los flujos de telecomunicación y telemática cuentan con unas características muy diferenciadas de las del conjunto de redes de transporte. De su estudio se desprenden dos características muy significativas: la jerarquía de control, ya que los flujos son marcadamente asimétricos, y ponen de relieve una vea más las desigualdades existentes entre las distintas provincias y, lo que es más importante, entre éstas y las grandes áreas metropolitanas; y la independencia espacial, puesto que la distancia juega un papel menor en la configuración espacial de los mismos, especialmente en el nivel más alto de la jerarquía metropolitana. Los flujos principales se dirigen siempre hacia aquellas provincias donde el nivel de actividad terciaria y la concentración poblacional es, independientemente de la distancia, mayor. Madrid domina la estructura nacional de los flujos telefónicos, seguida, a mayor distancia, de Barcelona.

Les réseaux que s'articulent à partir des fluxes de télécommunication et de télématique comptent avec des caractéristiques très différénciées des de l’ensemble de réseaux de transport. Deux caracteristiques trés significatives on se détachent de leur étude: la hiérarchie de domination, puis que les fluxes sont vraiement asymétriques et ils ressortent, une autre fois, les inégalités éxistentes entre les différentes provinces et, le plus important, entre elles et les grandes aires métropolitaines; et l'indépendance spatiale, puis que la distance joue un role moins important a la confifsUration spatiale des memes, sur tout au niveau le plus haut de la hiérarchie metropolitaine. Les fluxes les plus importants toujours s'adressent jusqu’à les provinces oú le niveau d'activité tertiaire et la concentration de population sont, indépendamment de la distance, le plus hautes. Madrid domine la structure nationale des fluxes téléphoniques, et après, un peu plus loin, on y trouve Barcelona.
