Authors: Sun Hao , Heo Young-Jung , Park Ji-Hye , Rhee Kyong Yop , Park Soo-Jin
Published: January 2021

Recently, photocatalysis technology has been widely considered as an effective method for solving environmental pollution issues and addressing the energy crisis. Hybrids of layered double hydroxide (LDH) exhibit excellent photocatalytic properties for use in the field of wastewater treatment due to the large interlayer spaces, chemical stability, and low cost. However, pristine LDH suffers from numerous limitations, such as insufficient visible light utilization and a high recombination rate of electron–hole pairs, resulting in degradation of photocatalytic performance. Recent advancements have demonstrated that LDH-based hybrids are suitable nanocomposites for photocatalytic applications when combining LDH with other semiconductors. This article summarizes the progress in the field of LDH-based ternary composites with emphasis on the removal of organic pollutants and heavy metal ions from aqueous media. Moreover, the applications and synthesis of LDH-based ternary composites, including corresponding examples, are discussed. In addition, the interaction mechanisms between photocatalysts and contaminants in water are comprehensively explained. Finally, the review provides insights into the challenges and prospects for the advancement of LDH-based photocatalysts.

Nanofluid bioconvective channel flow is an essential aspect of the recent healthcare industry applications, such as biomedical processing systems. Thus, the present work examined the influence of nth order chemical reaction in an unsteady nanofluid bioconvective channel flow in a horizontal microchannel with expanding/contracting walls. The suitable form of the similarity transformation is exercised to transform the governing boundary layer equations into a more straightforward form of system to ease the computation process. The Runge–Kutta method of fifth-order integration technique solved the reduced boundary layer system and generated the numerical results as the governing parameters vary. It is found that the destructive second-order chemical reaction enhances the mass transfer rate at the lower wall but deteriorates the mass transfer rate at the upper wall. The upper channel wall has a better heat transfer rate than the lower wall when the Reynolds number increases.

Published: January 2021

The purpose of this proposed investigation is to study unsteady magneto hydrodynamic (MHD) mixed initial-boundary value problem for incompressible fractional Maxwell fluid model via oscillatory porous rectangular duct. Considering the modified Darcy’s law, the problem is simplified by using the method of the double finite Fourier sine and Laplace transforms. As a limiting case of the general solutions, the same results can be obtained for the classical Maxwell fluid. Also, the impact of magnetic parameter, porosity of medium, and the impact of various material parameters on the velocity profile and the corresponding tangential tensions are illuminated graphically. At the end, we will give the conclusion of the whole paper.
Analytical approaches and preparation of biological, food and environmental samples for analyses of zearalenone and its metabolites
Authors: Gadzała-Kopciuch Renata , Kuźniewska Anna , Buszewski Bogusław
Published: January 2021

Zearalenone (ZEN) is a mycotoxin that occurs in all stages of plant growth and development and exerts harmful effects on humans and animals. Zearalenone is easily absorbed in the digestive tract, and it is metabolized in the intestinal wall and the liver. Zearalenone has several derivatives: zearalenone, zearalanone (ZAN), α-zearalenol (α-ZEL), β-zearalenol (β-ZEL), α-zearalanol (α-ZAL) and β-zearalanol (β-ZAL). These substances have a high affinity for estrogen receptors, and they can gradually affect the endocrine system. Excess ZEN and its metabolites are excreted with urine and bile. This paper analyzes ZEN metabolism and investigates the presence of ZEN and its metabolites in urine. Since the isolation of ZEN and its metabolites from different matrices still poses a significant problem, the paper also presents various sample preparation methods (including liquid-solid extraction, liquid-liquid extraction and other techniques) as well as sensitive and specific chromatographic techniques, including liquid chromatography (LC) with fluorescence and mass spectrometry detection, gas chromatography (GC) and thin-layer chromatography (TLC).
Detection of broken rotor bars of induction motors based on the combination of Hilbert envelope analysis and Shannon entropy
Authors: Kabul Ahmet , Ünsal Abdurrahman
Published: January 2021

Broken rotor bar (BRB) is one of the most common fault types of induction motors. One of the common methods to detect the broken rotor bars is the observation of the characteristic sideband frequencies in the stator current. If the motor is lightly loaded, the sideband harmonics are attached to the fundamental frequency of the main supply and the amplitudes of these harmonics are quite low. Therefore, it is difficult to detect the broken rotor bars under light loading conditions by using conventional motor current signature analysis (MCSA) methods. Moreover, in some cases, the sideband harmonics of fundamental frequency may exist although there is no rotor fault in induction motors due to load oscillations. Therefore, there is a risk for false broken rotor bars alarm with the existence of lower amplitude of harmonics. This paper provides an alternative approach for the detection of broken rotor bars by applying Hilbert envelope analysis along with Shannon entropy to stator current signals. The proposed method includes two-stage evaluation system to eliminate false BRB alarms such as detecting sidebands from envelope spectrum and calculating entropy rates from envelope signals. The results are verified experimentally under 25 %, 50 %, 75 % and 100 % loading conditions.

Authors:   University of Costa Rica, Rojas Carolina
Published: January 2021

This paper is about the simulations' systematization and evaluation, implemented over 13 years, as part of the training of Social Work students at the University of Costa Rica. As a product of the systematization, the simulations' theoretical foundation is detailed, integrated by student-centered approach, situated learning, and cultural-historical theory. Besides, the didactic process had two moments: first, the strategy preparation and implementation, and second the debriefing with all the participants. The evaluation was implemented in 2017, 2018, and 2019. A questionnaire was developed and completed by 60 students in these three years. The students consider the simulations as a more dynamic approximation to the knowledge provided by the course, through the practical approach to situations they will face in their professional practice. The students acquired several learnings with this training, on a theoretical, methodological, and technical level, as well as the development of skills for the attention of crises.

Cuarta parte. Pensar el medio ambiente: un desafío en américa latina. Capítulo 17. Cuando la tierra explotó: comunidad y territorio cambiantes por la extracción de petróleo en México
Authors: Svenja Schöneich
Published: January 2021

El camino para llegar hasta la comunidad nombrada por el héroe nacional Emiliano Zapata desde la ciudad de Papantla de Olarte, conduce a través del área verde y fértil del norte de Veracruz, conocido históricamente, más allá de los bordes del país, por el cultivo de vainilla. Hoy en día se estrechan grandes plantaciones de naranjales y limonares bordeando el camino, atravesando el paisaje accidentado con pequeños cultivos de maíz entre los cítricos. Siguiendo la carretera, pasando pastizales con ganado y más naranjales, el verde del paisaje es, otra y otra vez, entrecortado por plantas en forma cuadrada, pavimentadas con diferentes tipos de bombas o ajustadores en dónde se encuentran las conexiones de líneas y tubería de diferentes colores. Algunas se encuentran bajo tierra y se ven solamente elementos reguladores en las plantas, otras van en la superficie atravesando las plantaciones. Finalmente llegando a la comunidad Emiliano Zapata los visitantes son bienvenidos con la visión de una gran planta, justo en la entrada hacia la comunidad al lado de la carretera, en dónde en algunas horas del día el aire está lleno de olores ajenos de gas. Más adelante, ya llegando al centro de la comunidad, se ve una flama de varios metros de altura saliendo de una torre visible, atrás de unos árboles y se escucha las turbinas que producen un sonido fuerte, audible por casi todas las casas. Abajo del pequeño puente pasa un arroyo repetidamente contaminado por residuos o crudo que a veces son perceptible hasta arriba del puente, donde pasa la gente platicando en voz alta para acallar el ruido de las turbinas.

Published: January 2021

In this study, a wood-based X-type lattice sandwich structure was fabricated by an insertion glue method using medium density fiberboard (MDF) and plywood as panels. Birch was used for the core. The mechanical properties and failure modes of the wood-based X-type lattice sandwich structure were investigated by an out-of-plane compressive test, a short beam shear test, and their matching analytical models. The out-of-plane compressive test and the compression analytical model showed that the failure mode of the plywood and birch combination was mainly shear failure in the core. The cores were broken or had sliding surfaces, while the failure mode of the MDF and birch combination was mainly shear failure of the core at both ends. Although the compression properties of the MDF and birch combination were better, the specific strength and modulus of the plywood and birch combination was larger, which align with the characteristics of lightweight and strong strength. The failure mode of the plywood and birch combination was delamination at both ends of the panel or core breakage, which indicated that this combination had better short beam shear properties. The theoretical models of the compressive /short beam shear properties were in good agreement with experimental results obtained for the plywood and birch combination.
The Importance of Task-Based Learning and Focus on Form in Teaching Phraseology
Authors: Chrissou Marios
Published: January 2021

A controversial issue for teachers of German as a foreign language is the balance between content and form. This also applies to vocabulary work in the field of phraseology. The modeling of language competence in the communicative approach is based on the understanding of language as a means of communication. Accordingly, the primary claim of communicative language didactics is to go beyond the description of structures of the foreign language and to place appropriate, situated linguistic action at the center of teaching. Against this theoretical background, content-oriented approaches such as Task-Based Learning have emerged in foreign language didactics, which emphasize the communicative aspect of language and place the didactic emphasis on situated, authentic tasks. Nevertheless, this emphasis did not lead to the suppression of form-based approaches which consider precision in language mastery by focusing on formal aspects through exercises to be necessary and desirable.This paper examines the question of the importance of exercises and tasks in phraseology-based vocabulary work. Against the theoretical background of the approaches of Task-Based Learning (TBL) and Focus on Form (FoF), possibilities for the integration of content-oriented and form-focussing teaching concepts for the promotion of phraseological competence are shown by means of concrete examples. Furthermore, the question of their balance in teaching is discussed.

Published: January 2021

Com o rápido avanço da tecnologia e a globalização da economia, as cadeias de suprimentos tornaram-se mais complexas e evoluíram rapidamente para o que hoje é conhecido como redes de suprimentos. As empresas estão enfrentando os desafios não apenas da alta demanda de variabilidade e requisitos personalizados, mas também da influência das decisões operacionais de seus parceiros. Todos esses desafios tornam as cadeias de suprimentos mais instáveis e, portanto, mais vulneráveis a riscos e interrupções. Para contribuir com a relação do tema Riscos e Colaboração, é intenção dessa pesquisa apresentar se existem pontos comuns na abordagem literária a respeito destes dois temas em redes de suprimentos. O estudo apresenta possíveis convergências entre os temas, correlacionando o entendimento comum dado pela literatura e apontando perspectivas futuras. Também, estabelece atributos comuns aos dois temas, e sugere proposições e insights para novas pesquisas a respeito.

Authors: Vo Khoi Diep Ngoc
Published: January 2021

The paper presents the results of the evaluation of sludge decomposition ability from a municipal wastewater treatment plant by an aerobic process on the Mishimax device (MK-50). The principle of the process was based on the microorganisms activated by the bulking agent as a bio-carrier to decompose organics composition and increase the evaporation by heating. An average sludge amount of 30 kg/day was added into MK-50, with the moisture of 80.2 – 83.6 %, with the C/N ratio of around 22 - 35. The heated air with 50 oC in temperature was supplied into a rotary bioreactor during the experiment period. After every 30 days of fermentation, the results from three experiments showed that the sludge volume decreased from 83 - 85 %, the stabilization efficiency by dry weight of sludge reached at 32 - 39 %, corresponding to the average decomposition rate is 12 g/kg.day, the evaporation efficiency was more than 95 %. Sludge after stabilization process had the colour of brown-grey, pH of about 6.5 - 7.2, the humus particles with the size of less than 1 mm accounted for over 60 %, the evaluation of product indexes according to nutrients like TOC, T-N meet the standard of 10TCN 526:2002/BNN&PTNT. The stabilized sludge was used for growth plant test and compared to a market organic fertilizer under the same conditions of cultivation and monitoring. The initial results of this study were a basis for research of sludge treatment technology approaches to waste recycling orientation in urban areas in Vietnam.

Published: January 2021

El presente trabajo elabora una revisión interdisciplinar entre el concepto del “principio de incertidumbre” utilizado en Economía y su aplicación en el cuento “El guardagujas” de Juan José Arreola. La extrapolación del principio economista (Nieto de Alba, 1989) será trasladado hacia un análisis literario según las pautas que sugiere la metáfora narrativa (Garayalde, 2018). De esta manera, proponemos encontrar que el estado de incertidumbre, además de ser el detonante de la trama, funciona como un catalizador positivo al momento de tomar decisiones. Asimismo, este tipo de construcción del cuento, fomenta un papel participativo en el lector al brindar en la refiguración de la lectura, escenarios recreados o representados que lo auxilien en la toma de dichas decisiones. La incertidumbre aparece en la trama del cuento como un tipo de antagonista que pone en estado de alerta al protagonista ante el devenir de la vida. Juan José Arreola utiliza la disposición de su texto de una manera simbólica, plasmando a la vez los rasgos característicos de su escritura
Ante la ley y la experiencia del sentido en F. Kafka
Authors:   Universidad de Granada, Martín Arnedo Santiago
Published: January 2021

Me propongo en este artículo analizar la estructura y el sentido del relato breve Ante la ley de F. Kafka. No solo el autor lo consideró especialmente relevante, a juzgar por las veces que lo publicó, sino que condensa ejemplarmente su estrategia narrativa, pues muchos de sus rasgos se reflejan de nuevo por extenso en la novela donde se inscribe, El proceso. Las circunstancias de su gestación y la radicalidad de su planteamiento lo sitúan en una tesitura de carácter teológico, frente a otros enfoques interpretativos de perfil más sociológico o antropológico. Esta hipótesis queda reforzada cuando surgen sin dificultad paralelismos con otros relatos bíblicos. Además, las propias opiniones del autor, en quien vida y literatura aparecen tan inexorablemente unidas, apuntan más bien a una problematización de la existencia en su conjunto, y no concretamente a alguno de sus aspectos, de ahí la angustia y la incertidumbre que envuelve tanto al protagonista de sus escritos como al lector, que en vano desea encontrar una última pieza que dé sentido al conjunto

Authors: Mallik B. Basu , Nanda Saktipada
Published: January 2021

A mathematical model is developed in this investigation for studying the axi-symmetric flow of blood through a catheterized artery with multiple stenoses. Consideration of Newtonian character of blood is described following the report of Young (1968) and Srivastava (2009) with the
appropriate constitutive equation governing the flow. The boundary conditions appropriate to the problem under study are the standard no slip conditions at the artery and the catheter wall. Analytical expressions for impedance (flow resistance), the wall stress distribution in the stenotic
region and the shear stress at the stenosis throat in their non dimensional form are derived by using the model. The derived expressions are computed numerically and the results are presented graphically for different values of the rheological and other parameters. The study provides an insight
into the effects of catheter radius and stenosis height on impedance, wall stress distribution in the stenotic region and the shear stress at the stenotic throat.

RESUMO Entre as principais doenças que acometem o gênero Heliconia, destaca-se a antracnose (Colletotrichum sp.) interferindo na produção, no desenvolvimento e na qualidade das flores. Como alternativa de manejo tem-se a indução de resistência utilizando indutores bióticos e abióticos. Dessa forma, o presente estudo teve por objetivo testar indutores de resistência no controle da antracnose em genótipo de Heliconia psittacorum x sparthocircinata cv. Golden Torch cultivada em ambiente sombreado e a pleno sol e determinar a ativação de enzimas relacionadas à patogênese. Foram utilizados dois indutores de resistência usados em conjunto, um indutor biótico Bacillus subtilis e um abiótico o produto Acibenzolar-smetílico (ASM). O delineamento experimental empregado foi de blocos casualizados, num esquema fatorial 2x2 (duas condições de cultivo [telado nível de sombreamento (50%) e a pleno sol] x duas condições de indução de resistência [com e sem aplicação de indutores]), com três parcelas subdivididas de 3x3m, contendo 9 repetições com 2 perfilhos em cada subparcela para avaliação da severidade da doença e 5 perfilhos em cada subparcela para determinação das proteínas relacionadas à patogênese (PRP’s). Para a avalição da produtividade foi determinada uma área de 2x2m dentro de cada subparcelas. As coletas para análise enzimática de peroxidase, β-1,3-glucanase e proteínas totais iniciaram 24 horas após uma aplicação de indutores e foram coletadas nos tempos de 24, 48, 72, 96 e 120 horas após o tratamento. Os indutores de resistência usados em conjunto atuaram como elicitores na atividade da peroxidase e β-1,3 glucanase, além disso, as plantas cultivadas no ambiente sombreado apresentaram menor severidade e menor Área Abaixo da Curva de Progresso da Severidade (AACPS) quando comparadas com as plantas cultivadas a pleno sol. Nas subparcelas com tratamento os indutores reduziram a severidade da doença, mas não houve interferência para AACPS. Os indutores proporcionaram incrementos na produtividade de hastes florais, sendo de 68,65% nas plantas cultivadas em ambiente sombreado e 26,86% nas cultivadas a pleno sol.

RESUMO Este estudo teve como objetivo analisar a mudança nas práticas de trabalho no artesanato do Alto do Moura, em Caruaru-PE, diante dos desafios enfrentados para manutenção econômica e modos de fazer no século XXI. Recorremos à noção bourdieusiana de habitus como construto a partir da qual elaboramos a noção de tensão emergente como um instrumento teórico-empírico para orientar as observações e análises das permanências e mudanças nas disposições, relativas ao modo de atuar no ofício e à manutenção econômica, dos pesquisados. A pesquisa teve natureza qualitativa e adotou a análise de conteúdo temática das 36 entrevistas realizadas com artesãos-proprietários, proprietários de outros negócios e formadores de opinião e demais materiais empíricos. As tensões disposicionais emergentes na dimensão econômica foram identificadas na concorrência predatória entre membros da comunidade, na ambivalência do papel do atravessador e nas diferentes formas de gestão do negócio do barro. Na dimensão laboral, foram evidenciadas tensões entre os tipos de produção (por cópia, em série e autoral), na invasão das bonecas e no sentimento em relação ao tipo de produção.

Resumo Neste artigo discutimos as relações entre corpo, saúde, tecnologias e gênero, a partir da análise de aplicativos de monitoramento de ciclos menstruais e da gravidez. Nosso interesse central é analisar, da perspectiva de gênero, que corpos se constituem a partir das interfaces dos aplicativos, e que tipos de dados são produzidos nesses ambientes. Articuladas aos ativismos feministas ligados à tecnologia, propomos uma análise desses aplicativos que tratam da saúde reprodutiva feminina, procurando situá-los no contexto da ampliação das tecnologias da informação ligadas à saúde e ao monitoramento dos corpos (Lupton, 2014).
Em busca da cegonha: “tentantes”, “instamigas” e possíveis ativismos em redes sociais*
Authors: Allebrandt Débora , Freitas Camilla Iumatti
Published: January 2021

Resumo Pessoas que estão tentando ter filhos têm acessado redes virtuais e se identificando através da categoria “tentante”. Esse movimento se insere na ativação de redes sociais na busca por informações. Há na busca de redes sociais por “tentantes” uma quebra da regra de silêncio que permeia a infertilidade e o uso de reprodução assistida. Tais práticas foram, frequentemente, agenciadas por tabus, segredo e inseridas na esfera da intimidade. Nesse artigo nos propomos a refletir sobre como a criação de grupos e canais de tentantes em redes sociais pode ser vista ora como um fórum de busca de informações especializadas, ora como uma prática de ativismo virtual visando através de redes de biossocialidade desmistificar e eliminar os preconceitos relacionados à infertilidade. No entanto, a centralidade de mulheres como protagonistas desses canais e postagens parece manter um desses tabus: a culpabilização e a responsabilização das mulheres pela infertilidade. Para compreendermos esse complexo universo, analisaremos as trocas e as publicações no Instagram a partir do perfil de duas tentantes. Nossa aproximação com essas publicações problematiza o modo como as postagens agenciam práticas e têm impacto no universo on/offline. “Curtidas”, emojis e “intamigas” nos permitem uma chave para compreender como a tecnologia mais do que mediar relações, as constrói.

Authors: Fagundes-Pereyra Walter José , Petroianu Andy
Published: January 2021

Resumo: Este estudo foi realizado com o objetivo de avaliar o interesse por pesquisa científica dos estudantes de Medicina da Faculdade de Ciências Médicas de Minas Gerais. Foram avaliados 60 estudantes, que responderam a um questionário sobre a importância da pesquisa na formação médica, participação em evento médico-científico e ocorrência de publicação em periódicos. Observou-se que 90% dos estudantes têm interesse por pesquisa científica, 97,3% acham-na importante na formação médica e 95% gostariam de realizar trabalhos científicos na Faculdade (p < 0,05). Apesar disso, apenas um terço deles já haviam participado de trabalho científico e somente 7% possuíam publicação médicocientífica. Os alunos apontaram a falta de orientação específica, a falta de estímulo institucional e a falta de estrutura física adequada como os principais motivos para a não realização de pesquisa. Conclui-se que a falta de orientadores e de programas de incentivo para o desenvolvimento científico, além da falta de estrutura apropriada parecem ser os principais responsáveis pelo número reduzido de pesquisas, uma vez que os alunos estão dispostos a realizá-las e parecem compreender sua importância na formação acadêmica.

Resumo: Introdução: A integração entre as instituições de ensino e os serviços de saúde na formação de residentes médicos requer mudanças em ambas as partes envolvidas, principalmente no cenário assistencial, fazendo-se necessária remodelação da cultura dos atores sociais que constituem o SUS. Objetivo: O objetivo deste estudo foi efetuar, pelo mapeamento das forças, fraquezas, oportunidades e ameaças, o diagnóstico situacional da integração ensino-serviço em um Programa de Residência em Medicina de Família e Comunidade (PRMFC). Método: Trata-se de pesquisa-intervenção com preceptores e gestores de saúde de um município do estado do Ceará, no Brasil. Os dados foram coletados pela entrevista semiestruturada, submetidos à Classificação Hierárquica Descendente (CHD) com auxílio do software IRaMuTeQ, analisados conforme eixos da matriz SWOT (forças, fraquezas, oportunidades, ameaças) e discutidos com apoio da literatura. Resultados: As classes de cada CHD originaram os fatores de cada eixo da matriz SWOT, delineando como pontos fortes: parceria entre os agentes de integração e inclusão do residente no cotidiano das equipes; pontos fracos: distanciamento entre preceptor e instituição de ensino e ausência de estratégias de valorização da preceptoria; oportunidades: perspectiva de o programa servir como ferramenta de gestão da saúde; e ameaças: problemas na gestão dos equipamentos da saúde, com reflexos sobre a estrutura dos serviços, gestão do programa e qualidade da formação. Conclusões: A análise da matriz SWOT viabilizou a identificação de pontos fortes e fragilidades no PRMFC, viabilizando a elaboração de estratégias para o fortalecimento da integração ensino-serviço, na perspectiva de melhoria da gestão, formação e execução do cuidado em saúde.
Direitos reais secundários e planejamento urbano: uma alternativa às estratégias clássicas de pensar o território
Authors: Vieira Anderson Henrique , Alves Larissa da Silva Ferreira
Published: January 2021

Resumo O mais amplo dos institutos de direito real secundário, a enfiteuse, se insere de modo confortável em um rol de titularidades aptas a ampliar o acesso ao solo urbano bem como fomentar a segurança habitacional pela grande extensão de direitos de propriedade que dispõe o enfiteuta. Além disso, traz incluso o dever jurídico de edificar e melhorar o imóvel, podendo servir como uma eficiente ferramenta de gestão urbana pelas suas características de flexibilidade, justiça e funcionalização. Nesse cenário, o desenvolvimento deste instituto, conjugado ao planejamento urbano, é fator primordial para minimizar a perspectiva exclusiva, excludente e absoluta da propriedade e favorecer a promoção de políticas públicas de acesso à terra. Assim, objetiva-se neste artigo compreender como o planejamento urbano, estruturado sob o desenvolvimento de direitos reais secundários, pode contribuir para democratizar o espaço urbano. Para tanto, aplicou-se o método dedutivo e pesquisa bibliográfico-documental como procedimentos metodológicos. O principal resultado indica que a política liberal não admite um maior desenvolvimento dos direitos reais secundários, estruturando o planejamento urbano, porque tal arranjo é mais conectado com uma dimensão social/funcional da cidade e vai de encontro ao que o capital precisa manter para justificar e legitimar sua violência simbólica e fática de exploração.
El patrimonio contemporáneo en la ciudad histórica de Sevilla. La protección del Movimiento Moderno (1925-1975) desde el planeamiento urbanístico
Authors: Rodríguez-Lora Juan-Andrés , Navas-Carrillo Daniel , Pérez-Cano María Teresa
Published: January 2021

Resumen El concepto de patrimonio no ha dejado de evolucionar desde principios del siglo XX hasta la actualidad. Entre otros avances, se ha conseguido superar el valor de antigüedad como criterio principal a la hora de considerar un elemento como patrimonio. Como consecuencia, ha surgido el concepto de patrimonio contemporáneo para referirse al proceso de patrimonialización de edificios construidos a lo largo de los siglos XIX y XX, incluidos los surgidos del Movimiento Moderno (1925-1975). El presente artículo estudia la evolución en el reconocimiento de este patrimonio emergente en el caso de Sevilla, la capital de Andalucía (España). Su protección es analizada desde un enfoque eminentemente urbano, a través del instrumento urbanístico de Plan Especial de Protección. La investigación se centra en analizar la inserción progresiva del patrimonio contemporáneo en el planeamiento urbanístico de protección, en base al año en que se desarrolla el plan para cada sector de la ciudad (26 sectores en total). En consecuencia, el trabajo identifica las principales diferencias entre la salvaguarda del patrimonio ya consolidado y el patrimonio contemporáneo como un problema. La menor protección de este último supone un mayor riesgo de pérdida de valores y de su desaparición.

ABSTRACT Purpose: the objective of this paper is to verify the effect of speech therapy intervention program in patients with non-fluent aphasia due to stroke in language tasks related to verbal fluency in semantic and phonological categories. Methods: Patients with aphasia due to stroke were selected to take part in this study. Two groups were formed: diagnosed patients with Broca/transcortical motor aphasia (GA), and a control group (healthy individuals). GA took a fluency verbal task (FAS, other complementary categories: phonological /p/ /l/ and semantic: “fruits” and “names”). These patients were all engaged in a language intervention program developed by the authors of this study. GA received speech therapy sessions (ten sessions lasting for an hour once a week), following a specific language program. After the sessions, the patients were re-evaluated. Results: GA had statistical significant improvement in the verbal fluency task after the speech therapy program (p-value < 0,001). Conclusion: The speech language therapy program we proposed was efficient enough to show improvement in the results for GA in the verbal fluency task.

The aim of this study was to improve the acid resistance of a metakaolin-based geopolymer (MKG) by substituting metakaolin with calcium aluminate cement (CAC). The CAC was added at weight ratios of 5% and 10%. The raw materials were activated with a mixture of sodium hydroxide solution and sodium silicate solution. The cured MKG mortars were immersed in a sulfuric acid solution with a pH of 2 for 75 days. Tests for the volume of permeable voids, unconfined compressive strength (UCS) tests, thermogravimetric analysis and Fourier transform infrared spectroscopy were conducted before sulfuric acid immersion. It was found that the addition of CAC facilitated geopolymerisation and reduced the volume of permeable voids of the MKGs. Changes in UCS, ultrasonic pulse velocity, mass and length were monitored to evaluate acid resistance. It was found that the addition of CAC dramatically improved the acid resistance of the MKG due to the reduced volume of permeable voids and enhanced neutralisation capacity. The mixture with 10% CAC showed the lowest deterioration.
Improved drawdown facilities at three flood storage reservoirs
Authors: Pepper Andrew
Published: January 2021

The Hertfordshire and North London Area of the Environment Agency has 18 flood storage reservoirs (FSRs) which come within the remit of the Reservoirs Act 1975. Many have fixed flow control orifices, which cannot be changed when the reservoir is in operation. A review was carried out to determine the ability of the flow control systems to provide drawdown at these reservoirs, considering both the latest guidance on drawdown rates and the ability of the reservoirs to empty quickly to accommodate subsequent floods. The ratio of full storage volume to maximum allowable outflow was used to rank the 18 reservoirs, in order to identify whether investigations into additional drawdown facilities were needed. Three reservoirs were found to require alterations to their outflow controls so that they could provide adequate emergency drawdown. The works required at these three FSRs are described, all of which involve penstocks with differing methods of operation – two being remotely operated.

Published: January 2021

The article describes the great importance of the analysis of a work of art in the formation of socio-cultural competencies of students in accordance with the requirements of modern education. A curriculum is proposed for a specific solution to the problem. Methodological tool when learning the poem Mamytova “Burul tan will Gomoku” are the methods of self-building roles in the work to ensure active participation of each student. The teacher, who accepts the question from each student, through his individual ideas wants to explain to the aesthetic value, distributes the roles of the characters among the students, on the basis of which the student, depending on his role, participates in the disclosure of the ideological content of the poem. The lesson of such role-based learning also involves a proper understanding of the idea of the artwork, as well as bringing personal emotions and revealing his role belonging to him .If the student learns the established competencies and the ability to use them, the article conducts a scientific and theoretical analysis of the subject for its use in the pedagogical process.
