Un abanico para la condesa. Apuntes sobre el uso de flabella andalusíes en la Cataluña del alto Medievo
Authors: Duran-Porta Joan
Published: May 2021

En unos conocidos epigramas del autor mozárabe Cipriano de Córdoba se mencionan dos abanicos dedicados a unos condes Guifredo y Guisindis, para los cuales la historiografía ha propuesto su identificación con los condes barceloneses Guifredo el Velloso y Guinedilda. El objetivo del artículo es dar contexto a esta identificación y sostenerla con la única mención documental segura de la presencia de abanicos islámicos en los condados catalanes altomedievales. Esta se halla en una donación de bienes de comienzos de siglo x, firmada por el obispo Riculfo de Elna, hermano menor de Guifredo. Se añade una breve reflexión sobre la idiosincracia formal y material de los abanicos andalusíes a partir de su representación en los discursos iconográficos de los marfiles califales.

Published: May 2021

Objectives: This study aims to evaluate the relationship between sequence polymorphisms (SNPs) in the displacement-loop (D-loop) region of mitochondrial deoxyribonucleic acid (mtDNA) and systemic lupus erythematosus (SLE) in Chinese female patients.

Patients and methods: This cross-sectional study was conducted between May 2017 and October 2017. The mtDNA was extracted from the peripheral blood of 97 female SLE patients (mean age 40.8 years; range, 20 to 79 years) and 108 age-matched healthy controls (mean age 48.7 years; range, 22 to 78 years). The SNPs of mtDNA D-loop were verified by polymerase chain reaction amplification and sequence analysis. The allele frequencies of D-loop region were compared by the Chi-square test between SLE and control groups.

Results: The SNP accumulation in SLE patients was significantly higher than that in the controls (p=0.027, 95% confidence interval [CI]: 0.075, 1.210). The frequencies of the major alleles of the nucleotides 73G/A (p<0.001, odds ratio [OR]=1.241) and 195T/C (p=0.047, OR=4.318) as well as the minor allele of nucleotide 199T/C (p=0.048, OR=0.279) were significantly higher in the SLE patients than in the controls, which indicated that 73G, 195T and 199C allele in the D-loop of mtDNA were associated with the risk of SLE. Further analysis indicated that the reactive oxygen species level in the SLE patients was significantly higher than that of controls (mean fluorescence intensity ± standard deviation: 3054.333±256.099 vs. 2099.167±599.662, p=0.009, 95% CI: 321.243, 1589.091).

Conclusion: This study indicated the SNPs in the mtDNA may associated with the risk of SLE. Analysis of SNPs in the mitochondrial D-loop may help identify individuals who are at high risk of developing SLE.

Published: May 2021

Objectives: The aim of this study was to investigate the frequency of mitral valve prolapse between healthy females with generalized joint hypermobility and healthy controls.

Patients and methods: This observational, cross-sectional, controlled study included female individuals with generalized joint hypermobility (n=39, mean age: 20.5±1.1 years; range, 19 to 23 years) and healthy controls (n=42, mean age: 20.6±1.2 years; range, 18 to 23 years) between July 2017 and November 2017. The generalized joint hypermobility consisted of women with a Beighton score of ≥4, while the control group consisted of women with a Beighton score of ≤3. Echocardiography was performed to all participants. Mitral valve prolapse was defined as having single or bileaflet prolapse of at least 2 mm beyond the long-axis annular plane with or without mitral leaflet thickening.

Results: No significant difference was found in the age, height, body weight, and body mass index between the groups (p>0.05). The median Beighton score was 5 in the generalized joint hypermobility group and 2 in the control group. No mitral valve prolapse was detected in those with generalized joint hypermobility, while non-classical mitral valve prolapse was observed in one participant in the control group, indicating no statistically significant difference between the two groups (p>0.05).

Conclusion: Our study results suggest that the frequency of mitral valve prolapse is comparable between the women with generalized joint hypermobility and healthy controls. Based on these results, routine assessment of mitral valve prolapse is not recommended in this population.

Published: May 2021

Objectives: This study aims to evaluate polysomnography findings and risk factors for sleep-disordered breathing in patients with systemic sclerosis (SSc).

Patients and methods: Thirty-nine patients (2 males, 37 females; mean age: 51.1±12.5 years; range, 21 to 76 years) who attended to the Rheumatology Clinic of Trakya University Medical Faculty between March 2014 and May 2014 were included in the study. Thoracic computed tomography, pulmonary function tests, carbon monoxide diffusion tests, echocardiography, and all-night polysomnography in a sleep laboratory were performed in all patients. Demographic and clinical characteristics of the patients were recorded. The Apnea-Hypopnea Index (AHI) scores were calculated. Disease activity was examined using the Medsger Disease Severity Scale (MDSS). Possible risk factors for sleep-disordered breathing were evaluated.

Results: Using the AHI of ≥5 for obstructive sleep apnea (OSA), 21 (53.8%) of the patients were classified as having OSA. There were no significant differences between the groups with and without OSA in terms of steroid use (p=0.4), CT involvement (p=0.3), and Warrick (p=0.6) and MDSS scores (p=0.5). Age, body mass index (BMI), and mean oxygen desaturation index were found to be significant in the univariate analysis (p<0.1); however, the multivariate analysis revealed only BMI as significant risk factor of OSA (p=0.028). In the multivariate analysis, the mean saturation was found to be significant risk factor for high pulmonary artery pressure (p<0.001).

Conclusion: Although OSA is common in SSc, only increased BMI is a significant risk factor of OSA, but not lung involvement, Warrick scores, or MDSS scores.

Published: May 2021

En las siguientes líneas se pretende un acercamiento al «concepto» de Iglesia que surge del Concilio Vaticano II, especialmente de los ocho primeros números de la Constitución Dogmática Lumen Gentium, donde se define a la Iglesia como misterio. Para ello, en un primer momento, y por medio de una inmersión en los textos teológicos y magisteriales del inminente pre-concilio, comprobaremos cómo la doctrina emanada del Vaticano II engarza perfectamente con la tradición precedente. En un segundo lugar, tomando como base principal los citados números de la Constitución Dogmática sobre la Iglesia, nos adentraremos en el análisis del significado de la noción misterio en cuanto a su aplicación a la Iglesia, principalmente desde la óptica de su relación con Cristo.

O sagrado e a cidade: olhares simbólicos religiosos
Authors: Oliveira Jefferson Rodrigues de , Pacheco Junior Nelson Cortes
Published: May 2021

Durante um determinado período os estudos geográficos referentes as relações existentes entre o sagrado e o urbano foram negligenciados, relegando o fenômeno religioso no urbano a um plano secundário, focado apenas na visão holística de que toda cidade surge através de uma lógica de mercado, que cresce, se reproduz, agrega valores e capitais, favorecendo o processo de acumulação de capital, o desenvolvimento e a expansão do capitalismo. Assim, o objetivo principal deste trabalho é apresentar ao leitor uma outra visão relacionada a abordagem sobre o urbano, ou seja, a análise do sagrado como elo de formação das cidades. Desta maneira, caminharemos em busca de um resgate histórico e geográfico da formação e gênese das primeiras cidades, bem como os fatores que contribuíram para que determinadas localidades passassem a ser conhecidas como hierópolis ou cidades-santuário, devido a vivência de seus habitantes e frequentadores estarem relacionadas diretamente a uma determinada experiência religiosa, predominantes frente as outras funções econômicas. Porém, neste artigo, também debateremos que determinadas estratégias territoriais, também buscam oprimir o outro que não compartilha com as mesmas ideias religiosas impostas por um dado grupo.

Protection of Centrifugal Compressor System
Authors: A. Husayn Khalafullah
Published: May 2021

Surge and Choke phenomenon are the two unstable operating modes of a compression system. That surge mode occurs at mass flows below the so-called surge line, and the chock mode occurs at low pressure and high flow rate. These instability operation modes will reduce the compressor performance or even will be made damage to the compressor system [1-3]. There are many studies to prevent instability phenomenon by establishing control system to the ability to do that, but sometimes surge or chock phenomenon occurs although of this big effort.
So, for this reason, the paper focus on the protection system, introduced to detect and prevent surge and shock stall occurrence to reduce damages possibility and keep the production at minimum losses. This can be achieved by setting the mass flow rate, pressure ratio, and operating speed in a predefined area.
Depending on the data sets including measurements from compression systems of Sirt Oil Company, Libya, and performance characteristics curves and polynomial regression technique to define the operation area. The developed surge protection system was implemented on the Matlab Simulink program and presented in a simple form.

Published: May 2021

West African states have been gravely affected since the outbreak of the dreaded COVID-19 pandemic began. The socio-economic and political aspects of ECOWAS have been affected because most African states have not been able to curtail the virus and a cure has not yet been found. Therefore, economic activities were suspended for a while, but now states are getting and creating ways by which they could work around the global issue they face because things cannot return to the way they werebefore the virus. The paper focuses on the free movement protocol implemented by the Economic Community of West African States (ECOWAS) and how the pandemic has affected its activities, how flexible the protocol has been, and how they adapt to the new normal. This paper however, is based solely on secondary sources of data. This paper concludes that due to the corona virus, ECOWAS had to ban the free movement of persons and free trade due to the lack of a conducive end safe environment. This paper notes that West African states under ECOWAS are losing funds due to the ban, and this has been affecting their development.

This study examined the extent to which defensive silence affects the collaboration and creativity of employees within the banking sector. For the study, self determination theory was adopted as the theoretical framework. The study focused on staff with full employment in deposit money banks in the South-South states of Akwa Ibom, Bayelsa, Cross River, Delta, and Rivers. Focus would be on Rivers, Bayelsa and Akwa Ibom. The choice of these three cities and states was informed by proximity to the researcher. Preliminary investigation shows that a total of one thousand, four hundred and forty-one (1441) management and subordinate staff are in the eighteen (18) selected deposit money banks. The determination of the sample size was done using the Krejcie and Morgan (1970) table and the result was 302. Multiple regression was used to test the null hypotheses. Our findings revealed a significant relationship between defensive silence and both collaboration and creativity. The study further recommended that organizations need to ensure that both managers and employees have the necessary support to be creative and understand how to use it in their particular job situation.
Origin of the Kyaukmyet Low-Sulfidation Epithermal Gold Prospect, Monywa District, Central Myanmar
Authors: Oo Toe , Harijoko Agung , Setijadji Lucas
Published: May 2021

The Kyaukmyet prospect is one of the principal epithermal gold prospects in the Monywa District, Central Myanmar; its gold- and base metal-bearing quartz veins contain around 3 g/t gold. Ore minerals are mainly hosted by volcanic and volcaniclastic rocks of the Late Oligocene to Middle Miocene Magyigon Formation. The distribution of magmatic intrusions in the area is controlled by ENE-WSW trending faults; these faults are likely related to ore mineralization. Common ore minerals at the Kyaukmyet prospect include pyrite, sphalerite, galena, chalcopyrite, and electrum. They occur in mineralized crustiform-textured brecciated quartz veins and banded (colloform) and massive quartz veins. Mineralized rock is accompanied by silicification and propylitic and argillic alterations. The alteration mineral assemblages include quartz, adularia, calcite, chlorite, illite/smectite, sericite, and illite. Fluid inclusions in the quartz veins have homogenization temperatures ranging from 148 °C to 304 °C and salinities from 0.35 wt % to 2.75 wt % NaCl equiv. The quartz in the mineralized quartz veins was most likely precipitated at a depth ranges165-256 m below the paleosurface. The precipitation of gold at the Kyaukmyet prospect may have been formed by mixing large amounts of meteoric fluid with small amounts of magmatic fluid. The coexistence of liquid-rich and vapor-rich inclusions and presence of adularia and bladed calcite indicate that fluid boiling is caused the main mechanism of ore formation. The vein textures, ore mineral assemblages, alteration minerals and fluid inclusion data suggest that the Kyaukmyet prospect is a polymetallic low-sulfidation epithermal gold deposit.

Published: May 2021

A obtenção da cidadania no século XIX era um alvo perseguido por não poucos. Em um país que limitava esse direito a poucos elementos, estrangeiros e elementos que não possuíam um “nome de família” valiam-se de uma série de estratégias para alcançarem uma posição relevante no aristocrático Vale do Paraíba Fluminense. No entanto, também aqueles membros da “boa sociedade” procuravam criar e manter sua imagem diante de todos. Assim sendo, lançavam mão de instituições filantrópicas, religiosas, políticas e outras para se destacarem. Em Valença, situada na província fluminense, encontram-se alguns dos mais destacados exemplos disso, como o Conde de Baependy, criador e primeiro provedor da Irmandade da Santa Casa de Misericórdia, o Visconde do Rio Preto e o Comendador Manoel Antônio Esteves. Esse trabalho procurar demonstrar como agiram esses elementos, em demanda da inserção social, da cidadania e da construção da auto-imagem.

Theoretical Reflection of the Problems of Correlation of Social Ideals and Political Interests
Authors: Rozumyuk V. , Vasyltsiv O.
Published: May 2021

The article explores the theoretical reflection of the ratio of social ideals and political interests. The main approaches to the motivation of political activity and ideas about the most perfect social systemare highlighted. The scientific heritage of K. Marx and K. Mannheim is analyzed in detail on this issue and it is determined that large social groups (classes) present their interests in the form of ideals, or,in other words, social values and ideals are a concentrated expression (incl. and political) class interests. It is proved that ideas about social ideals and political interests have always been determined historically, being formed under the direct influence of the most important events in the international arena and the main domestic political trends. Thus, one can speak not only about theinterdependence of socio-political processes and knowledge about them, when theoretical ideas about society are a kind of reflection of its state and structure, and on the other hand, social relations appear to be objective knowledge about them (i.e., an empirical embodiment of ideas and concepts), but also about the synchronized dynamics of the evolution of social theory and historical practice, when scientific ideas develop in parallel with real social changes, creating two parallel dynamics – the intellectual and factual.

The features of the creation and activities of international left associations in the first third of the XXth century are analyzed, the features of the activities of the Second International on the eve andduring the First World War are clarified, the ideological contradictions between the Social Democratic parties in this period are characterized. The reasons for the splits in the Second International are highlighted; the processes that preceded the formation of the Third International (Communist International) and the Workers’ Socialist International are characterized. The reasons for the separation in the Second International, the processes of the formation of the Third International (Communist International) and the Workers’ Socialist International are investigated, and the organizational structures of the Comintern and the Workers’ Socialist International are compared. It is noted that after the October Revolution in Russia, the Bolsheviks increasingly influenced the world left movement. Promoting the ideas of the socialist revolution and the dictatorship of the proletariat, at the initiative of V. Lenin, they formed the Third International, uniting the communist parties. After the formation of the Comintern, a number of left-wing socialist parties severed relations with the International. The centrist parties rejected the conditions of the Bolsheviks, since the mid-1920s. They united around two centers: the Second International (London) and the Vienna 2½ International.

During autumn 1943 – spring 1944, a planned evacuation of the German population was carried out from the occupied Soviet regions. This contingent was temporarily housed in special camps inGermany, the General Government and the Protectorate of Bohemia and Moravia. Following the established procedure, all evacuated Germans from the USSR were subjected to mandatory checks bythe Central Immigration Office. According to its results, the decision about naturalization was made. Camp filtration was a complex procedure based on the doctrinal principles of Nazi ideology. Itallowed to determine both the level of ethnocultural identity and the racial characteristics of each refugee. The legal basis of filtration was different orders, disposals, and prescriptions of severalauthorities that were part of the SS apparatus. Although the German authorities tried not to deviate from the basic principles of this procedure, it was still forced to take into account that the contingentwho came from the USSR had certain socio-cultural characteristics: first, the national identity of many Germans was at a rather low level and secondly, among evacuees (mainly through mixed marriages)there was a significant percentage of people that belonged to other nationalities.

Energy management in grid-connected Micro-grids (MG) has undergone rapid evolution in recent times due to several factors such as environmental issues, increasing energy demand and the opening of the electricity market. The Energy Management System (EMS) allows the optimal scheduling of energy resources and energy storage systems in MG in order to maintain the balance between supply and demand at low cost. The aim is to minimize peaks and fluctuations in the load and production profile on the one hand, and, on the other hand, to make the most of renewable energy sources and energy exchanges with the utility grid. In this paper, our attention has been focused on a Rule-based energy management system (RB EMS) applied to a residential multi-source grid-connected MG. A Microgrid model has been implemented that combines distributed energy sources (PV, WT, BESS), a number of EVs equipped with the Vehicle to Grid technology (V2G) and variable load. Different operational scenarios were developed to see the behaviour of the implemented management system during the day, including the random demand profile of EV users, the variation in load and production, grid electricity price variation. The simulation results presented in this paper demonstrate the efficacy of the suggested EMS and confirm the strategy's feasibility as well as its ability to properly share power among different sources, loads and vehicles by obeying constraints on each element.

Information system (IS) is crucial in today’s educational institution. Academic information systems that provide reliable and well-presented information are essential for the university to improve strategic performance in management and decision making. To achieve educational-related goals, University makes investments in IS expecting positive impacts but often lacks post-implementation review. Thus, evaluation of IS “success” is an important aspect to ensure successful service delivery. This is indicated by the effective use of the system and the positive influence it has on their customers This is indicated by the effective use of the system and the positive impact on their customers. This study addresses factors that influence the successful implementation of the Academic Information System (AIS) using IS success models. The structural model has been tested using an empirical approach based on data collected from 187 active users of AIS. This study found compared to other quality dimensions, information quality has the greatest influence on user satisfaction. However, perceived system quality is not a significant predictor of system use and user satisfaction

En la actualización del programa de Biología IV del Bachillerato (ENP) de la UNAM señala que los profesores somos facilitadores de la enseñanza de los alumnos, esto significa que el alumno es el centro del proceso de enseñanza-aprendizaje mientras que el profesor proporciona el andamiaje necesario para guiarlo. Del mismo modo, dicho programa hace referencia al empleo de las TIC y las TAC durante el desarrollo de contenidos conceptuales y procedimentales. Por ello, empleamos los e-Books como herramienta digital para la construcción de conocimiento basado en el alumno, para dos temas de la Unidad 1 de dicho programa. El proceso fue el siguiente: primero, los alumnos realizaron búsquedas de información sobre las principales características y servicios ambientales de ecosistemas mexicanos. Después, para estructurar el trabajo, elaboraron un documento en Google Docs donde analizaron y sintetizaron su investigación. Finalmente, los alumnos elaboraron e-books con el fin de plasmar sus ideas y reflexionar sus conclusiones. Dicho material fue presentado en plenaria para desarrollar la difusión de ideas en público. En conclusión, los e-Books son herramientas digitales útiles para la construcción del aprendizaje centrado en el alumno, fomentan el trabajo colaborativo y forman parte de la alfabetización tecnológica, la cual es de suma importancia en la formación de nuestros educandos.
