Authors: AZAM MOHD ASYADI , R.N.A.R. Seman  , M.A. Mohamed  , M.H. Ani
Published: October 2022

One of the major elements in determining the supercapacitor performance is the development of a nano-layered structure through facilitating the surface-dependent electrochemical reaction processes. Carbon-based nanomaterials especially graphene, has attracted tremendous interest in electrical charge and power sources including supercapacitor because of their exceptional properties, which include high conductivity and large specific surface area. In this paper, the effect of polytetrafluoroethylene (PTFE) binder ratio (1, 5, 10, and 15 wt. %) on the electrochemical performance of graphene supercapacitor are evaluated. In addition, the facile and scalable preparation of graphene electrodes by using low-cost slurry technique is proposed. From the conducted experimental works, it was found that the fabricated graphene electrodes exhibit superior electrochemical properties for supercapacitor applications with a specific gravimetric capacitance of up to 373 F g−1. Moreover, the graphene electrode presented excellent cyclic stability with 99 % specific capacitance retention after 10,000 charge/discharge cycles hence promising for long‐lasting supercapacitors. The outcomes from the deliberated study serve as the basis of knowledge in the development of a cost-effective graphene-based materials production for energy storage devices.
Development of a Novel Spiral Duct Particulate Matter Separator for Internal Combustion Engines
Authors: Vashist Devendra , M. Bindra
Published: October 2022

In compliance with the stringent BS-VI emission norms, control of particulate matter in diesel engine exhaust emission is currently achieved through diesel particulate filters, catalytic convertors, and baffle filters of various designs. In the present study a device comprised of a spiral duct with an increasing cross-sectional area over the length is designed and developed. The duct has a lining of heat-resistant and porous material fixed along the inside walls. The inlet of the devices is connected to the outlet of the tailpipe of the exhaust system. The device will collect the particulate matter in the heat-resistant porous lining along the walls of the spiral. The developed device is simple, economical and easily serviceable. The developed spiral duct particulate matter separator was tested on diesel vehicles, and the smoke density of tailpipe emission was measured in terms of the light absorption coefficient. During the analysis it was found that there is a reduction in light absorption coefficient by 25.37%. The developed design also overcomes the clogging problem of the exhaust system, which is a cause of backpressure in the case of conventional particulate filters. The design of the device is such that it can be easily retrofitted in the existing fleet of vehicles, making them compliant with stringent statuary emission norms.
Bolívar, la revolución de Haití y la expansión democrática
Authors: Pachón Soto Damián
Published: October 2022

El artículo presenta una descripción sobre las estructuras coloniales hasta el siglo XVIII, alude a las reformas borbónicas para centrarse posteriormente en la Revolución de Haití de finales de ese siglo y comienzos del siglo XIX con el fin de determinar su influencia en el pensamiento republicano de Simón Bolívar. Se argumenta que la liberación de los esclavos, la eliminación de todo tipo de servidumbre, al igual que otros principios del republicanismo, son tomados por Bolívar de la Revolución haitiana más que del pensamiento político ilustrado francés e inglés. Se sostiene, finalmente, que la apuesta de Bolívar constituye un clásico ejemplo de la lucha por la expansión democrática de los derechos donde la educación, la virtud cívica, la lucha contra la corrupción y la búsqueda de sociedades más igualitarias son constitutivas del republicanismo.
Ser docente: un acto intrínseco de amor pedagógico
Authors: Alonso-Sainz Enrique
Published: October 2022

Volver la mirada hacia la esencia de la educación sin centrarse en lo exterior o lo fácilmente visible es un acto de valentía y rebeldía. En la educación, los focos se han puesto más en las acciones, metodologías y didácticas que entran en juego, que en desvelar y delimitar la definición misma de docente y por consiguiente sus características. En este ensayo, se usará la idea de amor pedagógico como hilo conductor para desgranar la figura del docente desde diferentes miradas y en todas sus etapas y ámbitos. Primeramente, se delimitará el objeto de estudio en torno al profesor capaz de enamorar a sus alumnos para, seguidamente, proseguir con la condición que se debe dar para que ese enamoramiento se haga palpable: estar enamorado previamente; y por último, se realiza una somera radiografía de la formación previa que reciben los profesores y que posibilita convertirse de enamorado a enamorador. Con todo ello, se concluye que el amor que puede albergar el alma de un maestro no es aquel amor romántico o atrayente hacia y por los alumnos, sino un amor pedagógico que convierte al profesor en un ser digno de admiración y de la profesión que asume.
La calidad educativa en Colombia: Factores internos y externos a la escuela asociados al mejoramiento de la misma
Authors: Diaz Palacios Jose Alfredo
Published: October 2022

Este artículo se presenta como resultado de la compilación teórica que, a través de las investigaciones llevadas a cabo por el autor sobre la calidad educativa en Colombia, permite reconocer ciertos factores que hacen referencia a la mejora de la calidad educativa y que en algunas oportunidades no se mencionan, o si se hace no se profundiza en la injerencia que tiene cada uno de ellos en la mejora de la calidad educativa. Dichos factores se han tenido en cuenta desde las diferentes perspectivas que se consideran luego de investigar sobre el concepto. En primer lugar, se presentan elementos que hacen parte del quehacer escolar y que se perfilan como coadyuvantes de la calidad educativa y se tienen en cuenta factores que han aparecido en estudios estadísticos como reportes desde la evaluación docente que se lleva a cabo periódicamente en Colombia o por resultados de las partidas presupuestales que destina el Estado para la mejora de la escuela en aspectos como la infraestructura escolar, los planes académicos de mejoramiento, etc. En segundo lugar, se profundiza en cada uno de estos aspectos, para después analizar su injerencia en la búsqueda de la calidad educativa; proponiendo alternativas a factores que a la postre no revisten la relevancia que esperan desde las entidades territoriales que regulan lo educativo; y al final, después del análisis que permite el artículo, se explica cómo el conjunto de los factores analizados contribuye a la mejora de la calidad educativa.
Etnografiando la escuela: descripciones de estudiantes de Pedagogía Básica en su inserción a la práctica docente
Authors: Bastías Bastías Lady Sthefany , González González Jaime Andrés , González Leiva Karla
Published: October 2022

La formación práctica y la respectiva inserción de los futuros/as profesores a las aulas está mediada por una serie de herramientas y tareas que estos deben realizar en los centros educativos que los reciben. En este contexto se presenta una experiencia pedagógica realizada en una universidad chilena con presencia regional, con el objetivo de implementar el uso de la bitácora etnográfica en la asignatura de Inserción a la Práctica de estudiantes del tercer año de la carrera de Pedagogía Básica. El desarrollo de esta experiencia permitió conocer, a partir del registro en bitácoras, las brechas que los y las estudiantes tienen sobre el hecho de identificar y describir un hecho o situación pedagógica, pero también permitió conocer las temáticas que consideran relevantes durante su experiencia práctica. Los aprendizajes de esta experiencia también mostraron que se debieron focalizar los objetivos, debido a que se dejó de lado la reflexión pedagógica sobre la situación pedagógica descrita.
Programa de acogida para el alumnado de 1.º de Educación Secundaria Obligatoria (ESO) en Institutos de Educación Secundaria (IES) de la Comunidad de Madrid
Authors: Muñoz Agustín
Published: October 2022

Como resultado de la investigación llevada a cabo mediante grupos de discusión con alumnado y profesorado de 1.º de ESO abordada en la realización de mi tesis doctoral «Tutoría en 1.º de la ESO. Necesidad de adultos de referencia en el paso del CEIP al IES en la Comunidad de Madrid», me propongo presentar un programa de intervención en el ámbito educativo para dar respuesta a la necesidad de la acogida en el tránsito del CEIP al IES y evitar, según las propias manifestaciones del alumnado, sentimientos de frialdad en el trato, falta de cariño y soledad, y en el que la figura del tutor jugará un papel primordial según expresan tanto profesores como alumnos. Será pertinente, en primer lugar, fundamentar el marco teórico para sentar las bases acerca de la definición de programa de intervención educativa, cuál sería su situación en el marco general de la intervención y conocer sus ejes vertebradores y características. A continuación, se expondrán las fases concretas que tendremos que recorrer para formular nuestro programa de intervención. Por último, presentaré las evaluaciones recogidas durante 4 cursos educativos en el IES Eijo y Garay de Madrid.
Programa de intervención socioeducativa «Mañanas activas». Una experiencia innovadora en un centro de educación secundaria del noroccidente asturiano
Authors: López Catalán María
Published: October 2022

«Mañanas activas» es un programa de intervención socioeducativa que responde a la necesidad de promover actividades de reflexión y de trabajo colaborativo y cooperativo ante comportamientos disruptivos. La propuesta implica utilizar medidas educativas en lugar de la sanción y la expulsión del alumnado de Educación Secundaria Obligatoria (ESO), actuando sobre los factores de riesgo y protección frente al abandono escolar mediante intervenciones específicas dirigidas a colectivos que estén en riesgo de vulnerabilidad. El programa fue impulsado inicialmente desde el Departamento de Orientación del IES Marqués de Casariego (Asturias), como parte de un Proyecto de innovación pedagógica («Diversidad activa»). Se realizó durante el curso 2020/2021, en el centro educativo y dentro del horario lectivo. Estaba dirigido a alumnado de ESO derivado por el equipo docente por presentar unas características específicas: mostrar comportamientos disruptivos en el aula o centro educativo, presentar baja motivación hacia el aprendizaje y/o experiencias de fracaso durante su historia escolar. La experiencia fue valorada positivamente por el alumnado, el profesorado y las familias del centro educativo. Este trabajo pretende describir las principales características teóricas y metodológicas del programa, su proceso de implementación, así como hacer una breve evaluación del mismo. La intención es abrir la posibilidad de su transferencia a otros contextos.

Artroplastia total de cadera en paciente con enfermedad de Paget: presentación de un caso
Authors: Restrepo-Noriega Victoria Eugenia , Serna Maya Iván Darío , Guzmán-Benedek Diego L. , Corrales-González Manuela
Published: October 2022

Introducción: La enfermedad de Paget es un trastorno metabólico de etiología desconocida, secundario a un incremento en la función de los osteoclastos y la consecuente respuesta de los osteoblastos a la formación exagerada de hueso. Compromete con mayor frecuencia el fémur proximal y, a menudo, se diagnostica incidentalmente. Se presenta el caso de una mujer con antecedente de enfermedad de Paget y pseudoartrosis de cadera izquierda, con indicaciones de prótesis total de cadera izquierda y un episodio único de luxación, sin complicaciones posteriores y una adecuada evolución.

Conclusión: El manejo quirúrgico en casos de fractura de cadera permite restablecer la marcha y mejorar la calidad de vida de los pacientes con enfermedad de Paget. A pesar de ser una patología que dificulta el manejo de los pacientes, la enfermedad de Paget no es una contraindicación para la artroplastia total de cadera y permite mejorar el dolor y recuperar la funcionalidad
¿Es seguro el ácido tranexámico en la cirugía de reemplazo total de rodilla de pacientes con enfermedad coronaria?
Authors: Costantini Julián , Esteves Tomás Alfredo , Nicolino Tomás Ignacio , Carbó Lisandro , Costa Paz Matías
Published: October 2022

Introducción: El ácido tranexámico reduce la pérdida sanguínea y los requerimientos de transfusiones luego de un reemplazo total de rodilla. Una de sus contraindicaciones relativas son los antecedentes de colocación de prótesis intravasculares coronarias, por un supuesto aumento de eventos tromboembólicos.

Materiales y Métodos: Análisis retrospectivo de pacientes sometidos a un reemplazo total de rodilla primario y de revisión que recibieron ácido tranexámico y tenían antecedente de colocación de prótesis intravascular coronaria. Se los comparó con un grupo sin estas prótesis. Se analizó la presencia de cualquier cambio clínico o electrocardiográfico de oclusión coronaria aguda, eventos tromboembólicos, el requerimiento de transfusión sanguínea y el nivel de hemoglobina pre y posoperatorio.

Resultados: 57 pacientes (59 cirugías, 56 reemplazos primarios y 3 revisiones) con colocación de prótesis intravascular coronaria, al menos, un año antes de la artroplastia. Un paciente tuvo síntomas de síndromecoronario agudo y cambios en el electrocardiograma. No hubo diferencias en la cantidad de eventos tromboembólicos. Solo un paciente del grupo de control recibió una transfusión de glóbulos rojos. El sangrado relativo fue menor en el grupo coronario independientemente del uso crónico de aspirina y clopidogrel antes de la cirugía (2,09 vs. 3,06 grupo de control; p = 0,01). En pacientes del alto riesgo, el ácido tranexámico no se asoció con más eventos tromboembólicos.

Conclusiones: El ácido tranexámico impresionó ser seguro y efectivo en nuestro grupo de pacientes con prótesis intravasculares coronarias; sin embargo, se necesita un estudio prospectivo con más casos para confirmar estos resultados

Os filhos indesejados da Nação
Authors: Neto Marcelo de Sousa
Published: October 2022

No Piauí, o que se observou é que o projeto vitorioso de Independência foi o das elites locais, formadas a partir de influentes grupos familiares e que já faziam parte da administração provincial. Para essas elites, transformações político-sociais representavam uma prédica, com vistas na manutenção de seus interesses no novo arranjo político do Brasil. Contudo, no Piauí, o processo se deu de maneira árdua e prolongada, marcado por combates, alianças e contradições internas de diversos setores da sociedade, em que grupos populares, em sua maioria composta pela população empobrecida da Província, se uniram às elites em uma luta comum contra a Coroa portuguesa, àquele instante apresentada como a responsável por todos os seus males e mágoas. Em meio às lutas, os grupos dirigentes buscavam a manutenção de seus interesses, ao tempo que as camadas populares, os filhos indesejados da Nação, lutavam por sua inserção na nova ordem. Dessa forma, são discutidos no presente artigo o processo de adesão dos grupos familiares locais a causa separatista, suas movimentações no cenário local em contraponto às movimentações em outras capitanias e na sede da Colônia e como foram estabelecidas alianças provisórias com grupos populares locais, tomando como metodologia a revisão da literatura existente sobre o tema a partir do estudo da História das Famílias.

Authors: Ferreira Stéphane Figueiredo , Bettega Maria Odette de Pauli
Published: October 2022

O presente artigo teve como objetivo compreender como se constituem as relações de poder entre professor e aluno em sala de aula nos últimos dez anos. A pesquisa transpassa o conceito de autoridade, de poder e sua influência nas organizações. O recorte histórico leva em consideração algumas mudanças na sociedade, como o avanço tecnológico, a violência nas escolas, a constituição da família e as relações de trabalho, com base em referenciais teóricos como: Bauman (2013); Cortella (2000), Castells (2016), Foucault (1987), Furlani (2004), dentre outros autores e dados de institutos de pesquisa. Com abordagem quali-quantitativa, a coleta de dados foi realizada por meio de questionário online, criado a partir da ferramenta Formulários Google e enviado através da rede social Facebook e do aplicativo de mensagens WhatsApp, no período de 15 de outubro a 27 de novembro de 2018. Foram 18 perguntas, sendo que quatro eram fechadas e 14 abertas, com obtenção de 50 respostas. Do total, 44% dos entrevistados eram do Espírito Santo, mas há dados de outros estados da região sudeste, norte e sul do país. A análise dos questionários apontou que mudanças ao longo de dez anos incidiram sobre a escola. O acesso à informação por meio da internet e das redes sociais, a mudança estrutural nas famílias e questões relacionadas ao trabalho puderam ser observadas claramente nas respostas.

Published: October 2022

O objetivo foi verificar como a prática docente, frente ao planejamento, à execução e à avaliação das atividades desenvolvidas em sala de aula, promove ou suprime a negligência de conteúdos do componente curricular de Ciências da Natureza. Realizou-se uma investigação qualitativa do tipo estudo de caso. O locus foi escolas públicas da região metropolitana de Porto Alegre/RS, Brasil. Para a coleta de dados, utilizou-se a entrevista semiestruturada, a partir de uma questão confrontativa baseada na realidade, e a observação direta de aulas. Participaram da entrevista dez professores de Ciências da Natureza do Ensino Fundamental dos anos finais. O método de análise de dados foi a Análise Textual Discursiva. Buscou-se como enfoque a apresentação da categoria emergente “planejamento, execução e avaliação das atividades em aula”, a qual apresenta um maior número de argumentos relacionados àquestão norteadora e ao objetivo da investigação. Por fim, observou-se que a falta de planejamento, a execução das aulas de forma transmissiva e a avaliação baseada na memorização de conceitos, não atendendo às necessidades dos estudantes quanto a sua formação como cidadãos, são fatores relacionados à prática de negligenciar conteúdos no Ensino de Ciências.

The potential addictive mechanism involved in repetitive nonsuicidal self-injury: The roles of emotion dysregulation and impulsivity in adolescents
Authors: Liu Jinmeng , Gao Yemiao , Liang Chunxi , Liu Xia
Published: October 2022

Background and aims

Nonsuicidal self-injury (NSSI) is highly prevalent in adolescents and is associated with various mental health problems. Repetitive NSSI (R-NSSI), as an extreme manifestation of NSSI, is a growing concern and has been proposed as a behavioral addiction. However, little is known about the potential addictive mechanisms of NSSI. This study aimed to examine the mediating effect of emotion dysregulation and the moderating effect of impulsivity using the Interaction of Person-Affect-Cognition-Execution (I-PACE) model in adolescents who repeatedly engage in NSSI.

Methods

A total of 3,915 adolescents (mean age = 13.21 years, SD = 0.87, 57.6% male) were recruited from three middle schools. Relevant questionnaires were used to evaluate childhood maltreatment, emotion dysregulation, impulsivity, and NSSI. Mediation and moderated mediation analyses were conducted separately for adolescents with occasional NSSI (O–NSSI) and R-NSSI to assess the relationship between childhood maltreatment, emotion dysregulation, impulsivity, and NSSI frequency.

Results

Our study found that childhood maltreatment was directly related to NSSI and indirectly related to NSSI through emotion dysregulation in both the R-NSSI and O–NSSI groups. Furthermore, impulsivity played a moderating role in the relationship between emotion dysregulation and NSSI in the R-NSSI group but not in the O–NSSI group.

Discussion and conclusions

The findings suggest that a high level of impulsivity and a high level of emotion dysregulation may be important risk addictive factors of NSSI through childhood maltreatment. Strengthening the emotion regulation skills and inhibitory control of adolescents with NSSI would be helpful to reduce their self-injury behaviors and maintain their mental health. This finding also supports the validity of the I-PACE model for evaluating R-NSSI.
Bounds for the electrical resistance for non-homogeneous conducting body
Authors: Ecsedi István , Baksa Attila
Published: October 2022

A mathematical model is developed to determine the steady-state electric current flow through in non-homogeneous isotropic conductor whose shape has a three-dimensional hollow body. The equations of the Maxwell's theory of electric current flow in a non-homogeneous isotropic solid conductor body are used to formulate the corresponding electric boundary value problem. The determination of the steady motion of charges is based on the concept of the electrical conductance. The derivation of the upper and lower bound formulae for the electrical conductance is based on Cauchy-Schwarz inequality. Two numerical examples illustrate the applications of the derived upper and lower bound formulae.
Theme Songs without Words
Authors: Rosar William H.
Published: October 2022

When Max Steiner arrived at RKO Studios in late December 1929, he came as a seasoned Broadway conductor and arranger to work on musicals. Applying the art and craft of song arranging from musical comedies on the Broadway stage to so-called “theme songs” that were sung in dramatic films in the early talkies, he developed what came to be known as “the big theme” in Hollywood Golden Age film scoring parlance in which a song-like theme was featured instrumentally as background music rather than sung on screen. In conjunction with this practice, Steiner and his Hollywood cohorts continued and adapted the existing dramatic techniques of silent film accompaniment to “talking pictures,” which, because of music playing under dialog, was given the name “underscoring.”
Composing, Casablanca, and the Film Music of the Golden Age
Authors: Wegele Peter
Published: October 2022

Max Steiner was one of the most productive composers in the history of film music. In 1939, for example, he composed twelve scores for feature films, including his magnum opus, Gone with the Wind. Steiner was under constant pressure to meet studio deadlines, yet he always managed to deliver his scores on time. Even during his busiest years, under an enormous workload, Steiner achieved remarkable consistency in the quality of his music. In order to explain the method behind Max Steiner’s ability to work quickly while maintaining high artistic standards, this article will discuss his working routine and will analyze a brief excerpt of his music for the classic film, Casablanca.
Music, Magic, and Humor
Authors: Butler Stephen
Published: October 2022

If you are a student of film music researching the life and work of Max Steiner, there are some things you should know, especially if you are working from a country other than the United States. In 2006–2007, my wife Jane and I traveled to three of the cities with which Steiner is most closely associated (Vienna, London, and Los Angeles) and visited Brigham Young University (BYU) in Provo, Utah, where the composer’s personal papers have been stored since 1981. This article details those journeys, taken in a strange parallel to Steiner’s own. These include Steiner’s experiences as a child prodigy from an established theatrical family in Vienna; conducting in London and the United Kingdom’s theatrical circuit; a career on Broadway, working with Victor Herbert, George Gershwin, Fred Astaire, and many other theatrical legends; and his final, thirty-five-year career as one of the founding fathers of modern film composition in Hollywood. Furthermore, the internet has made many more materials available to the scholar, including BYU’s developing online thematic catalogue. The “net” result is that future students will have an incredible amount of material available to them, much more than those of just thirty years ago.

Published: October 2022

Objective: To synthesize the evidence of the effectiveness of topical treatment compared to the systemic treatment for pain control in Malignant Fungating Wounds (MFWs) in adults.
Introduction: Approximately 14.5% of cancer patients present MFWs due to the increased survival rate of oncology treatments, and 85% report pain in the wound. Previous systematic reviews on the subject have explored MFWs-related symptoms (bleeding, foul odor, and exudate) but without results concerning the pain. A recently published scoping review mapped 20 proposals for topical treatment of MFWs-related pain, originated in different studies designs. Currently, there is a need to carry out an effectiveness review in order to facilitate clinical evidence-based decision-making.
Inclusion criteria: Quantitative studies on the effects of topical therapies for pain control in MFWs compared to systemic treatments in adult patients in English, Portuguese, and Spanish without any time limits. Studies that do not meet 70% of the methodological quality threshold will be excluded.
Methods: A review of effectiveness according to the JBI methodology. The titles and abstracts of identified records will be checked for the inclusion criteria, and the selected papers will be reviewed in their entirety for their relevance to the objective. The selection of the studies will be carried out according to the defined threshold of the assessment of the methodological quality using the JBI Critical Appraisal Checklist instruments, and the data of interest will be extracted by two reviewers. Finally, the data synthesis will be presented in a narrative and/or statistical summary.

EARLY DETECTION AND MANAGEMENT OF THERMAL RUNAWAY IN BATTERIES USING WATER MIST FOR AIR PRECOOLING
Authors: Jana Aritra , Saha Ranadip , Pal Debamita , Sarkar Sourav , Mukhopadhyay Achintya
Published: October 2022

In the present study, the use of air, precooled with a water mist for management of thermal runaway of a lithium ion cell is studied. A lumped capacitance model of the battery based on ordinary differential equations representing thermal transport and chemical kinetics of a 18,650 NCA/graphite cell based on Arrhenius electrochemical equations is used to simulate the thermal behavior, and an efficiency factor is used to account for the venting of the cell. An Eulerian approach is used for the evaporation of water mist. Both convective and radiative heat transfer are considered for modeling the heat transfer for the lithium cell. For convective heat transfer, flow across a cylinder is considered for maximizing heat transfer. Additionally, two basic methods of triggering mist precooling based upon the temperature of the battery and solid electrolyte interphase degradation were tested. Based upon the results, a conclusion was drawn that mist precooling triggered using temperature as a parameter can be an effective method to control thermal runaway.
SELF-QUADPLEXING SLOT ANTENNA FOR S- AND C-BAND APPLICATIONS
Authors: Nigam Padmini , Shenoy Venkatesh
Published: October 2022

This paper demonstrates a novel kind of cavity-backed self-quadplexing slot antenna for S- and C-band applications. The proposed antenna consists of four distinct U-shaped slots of different lengths and produces quad frequency bands for wireless communication systems. These slots are excited through separate and orthogonally placed 50 Ω micro-strip feed lines and generate four distinct operating bands at 3.2, 4.1, 5.8, and 7.2 GHz. Due to the perturbation of the different U-shaped slots over a substrate-integrated waveguide cavity with defined positions, the high intrinsic port isolation value is better than 30.5 dB. Thus, the proposed unique antenna structure combines the four independent operating bands with minimum mutual coupling and negligible interference among the input ports, showing the antenna's self-quadplexing feature. The proposed antenna also has frequency tunability with unidirectional radiation patterns and gains of 5.8, 5.4, 4.01, and 3.47 dBi at corresponding operated frequencies. The cross polarization is below 17.3 dB and the front-to-back ratio is higher than 21.5 dB at all operating quad bands. Good agreement was obtained between the simulated |S| parameter and equivalent circuit model results.
Intervención educativa sobre lactancia materna en estudiantes de quinto semestre de facultades administrativas de la Universidad Cooperativa de Colombia, sede Santa Marta, en 2022
Authors:   Universidad Cooperativa de Colombia, Martínez Ospina Rosa Amalia
Published: October 2022

Colombia es de los países con más fecundidad adolescente en el mundo. Una tercera parte de los embarazos son de jóvenes menores de 18 años, aproximadamente un 20% de 15 años. Existen pocos estudios sobre intervenciones educativas de lactancia materna en el contexto universitario. Que la población se eduque prolonga los conocimientos en las familias a las que pertenece y probablemente sean replicadores de conocimientos científicos y se disminuyan los mitos sobre la lactancia materna en el interior de su círculo social. El objetivo de este estudio es realizar una intervención educativa sobre lactancia materna en estudiantes de quinto semestre de facultades administrativas de la Universidad Cooperativa de Colombia, sede Santa Marta, en el 2022. Se planteó un cuestionario previamente validado que evaluó conocimientos previos sobre lactancia materna. A partir de allí, se pretendió enfocar la intervención educativa con los aspectos por mejorar o fortalecer. La mayoría conoce las complicaciones que puede presentar un niño si no se alimenta con leche materna. El 38% reconoce solo una ventaja de la lactancia. Solo el 37,5 % sabe a quién pedirle ayuda en caso de desconocimiento de la lactancia. El 12 % de las personas encuestadas posee desconocimiento con respecto a la frecuencia con la que se debe amamantar a un bebé. Actualmente, la fase de intervención y evaluación posintervención se encuentra en planeación.
EFFECT OF INITIAL TEMPERATURE ON THE MICROSTRUCTURE AND PROPERTIES OF CRYOGENIC ROLLED AZ31 MAGNESIUM ALLOY
Authors: Wu Zhenyu , Zhi Chenchen , Ma Lifeng , Zheng Zebang , Zhu Yanchun , Jia Weitao
Published: October 2022

By characterizing the properties of a twin cast-rolled AZ31 sheet after cryogenic rolling, the effects of the initial temperature on the microstructure and mechanical properties of the sheet obtained by cryogenic rolling were studied. The results indicate that the hardness of the alloy was a maximum due to the high-density dislocations in the microstructure when the initial temperature was room temperature. The highest yield strength and elongation appeared at the initial temperature of 200 °C, and the microstructure was mainly fine equiaxed grains. It was observed that fine grains increased, and the yield strength and elongation gradually decreased with the increase of the initial temperature. The overall trend of yield strength and elongation increased first and then decreased. Based on the results of different initial temperature treatments, the optimal microstructure and properties of AZ31 magnesium alloy were acquired when the initial temperature was 200 °C.
PLASTER CHARACTERISTICS OF BYZANTINE WALL PAINTINGS IN WESTERN ANATOLIA
Authors: Şerifaki Kerem , Böke Hasan
Published: October 2022

In this study, the execution technique and material characteristics of the plaster layers of Byzantine wall paintings from three archaeological sites (Anaia, Olympos and Aigai) from western Anatolia were examined for the purpose of their conservation. Throughout the study, mineralogical and chemical composition of the plaster layers were determined with a scanning electron microscope coupled with an X-ray energy dispersive system (SEM-EDS) and X-ray diffraction analyses (XRD). Reflected light microscopy (RLM) and SEM studies conducted on polished cross-sections of samples revealed the stratigraphy and microstructural properties of the plaster layers of the Anaia Church (4th–12th centuries), Başpınar Church (13th century) in Olympos and a Byzantine settling and the Chapel (13th century) in Aigai. Throughout the research, pure lime and aggregates in the plasters of Aigai, as well as magnesium-rich lime and straw in the plasters of Anaia and Başpınar were determined. The plasters from the Anaia and Başpınar Churches exhibit characteristics similar to the samples from the post-iconoclastic period due to a similar raw-material use. In the samples from Aigai, plastering techniques such as marmorino, intonachino and cocciopesto, indicating earlier periods, were observed. As a result of this study, it was concluded that the number and characteristics of the plaster layers from the paintings had been applied intentionally in accordance with the technique of the painting. Plaster characteristics of the wall paintings in western Anatolia from the Byzantine period were found to be similar to the ones in İstanbul, the Balkans, Crete and Cyprus. The results of this study will guide the conservation efforts of the wall paintings.
MAGNETICALLY CONTROLLED GROWING RODS FOR THE TREATMENT OF EOS: EXPERIENCE FROM A SINGLE CENTER AND XPS SURFACE ANALYSIS OF THE RODS

Published: October 2022

The treatment of early-onset scoliosis (EOS) remains one of the biggest challenges in paediatric orthopaedics. Magnetically controlled growing rods (MCGRs) have increased in popularity compared to traditional growing rods (TGRs), providing curve correction, spinal growth and a reduction of the associated surgical trauma. Between May 2015 and July 2022, 24 patients with EOS were treated with an MCGR system using a standardized implantation procedure. An ultrasonography- or radiography-controlled distraction of 3 mm every 3 months was performed. Whole spine radiographs were taken pre-operatively, post-operatively, and in six month interval. The Cobb angle, T1-S1 height, and growth were measured. All the patients had a dual-rod construct implantation. The mean age of the surgical patients was 8 years (6–11), and the mean follow up was 39 months (2–84). The etiology of the EOS was syndromic in six patients, congenital in two, idiopathic in three and neuromuscular in 12. One patient had a conversion from TGR, and one patient had a concomitant resection of hemivertebra. The mean preoperative Cobb angle was 69° (30–108°), postoperative was 38° (16–66°), and 38° (9–69°) at final follow-up. The mean pre-operative T1–S1 length was 289 mm, increasing to 326 mm post-operatively, and 353 mm at the final follow-up. The mean spinal growth was 64 mm (26–110 mm). Two retrieved rods were examined using X-ray photoelectron spectroscopy (XPS). A surface analytical technique to determine the surface chemistry after exposure of the rods in the body. The MCGR system represents a safe and less invasive option for the treatment of EOS.

Waste tyre-rubber disposal is a serious global problem, posing a severe danger to the environment. This present study aims to investigate the performance of concrete utilizing recycled tyre-rubber waste as a partial replacement for natural fine aggregate. Three different sizes of crumb rubber were combined to produce a well-graded sample. Based on various trials, mixed proportions of M30 grade concrete and the crumb rubber replacement percentages were determined. The test specimens were prepared. Experimental investigations have been carried out to study the mechanical, durability and temperature properties of the developed Crumb rubber concrete (CRC). In this study, crumb rubber replaced the fine aggregate in various percentages, such as (0, 5, 7.5, 10 and 15) %. Microstructural analysis was also carried out with EDX and scanning electron microscopy (SEM) to visualize the performance of rubber with CSH gel under different temperature conditions. The study found that (CRC5) a 5 % replacement of crumb rubber is the optimum percentage to replace the natural fine aggregate to develop the crumb rubber concrete. The durability tests concluded that the proposed model of rubberized concrete is suitable for any structural elements exposed to acidic environmental conditions.

Authors: ERSOY Ersan
Published: October 2022

This study aims to analyse the factors that influence the capital structure decisions of Turkish listed textile and apparel firms over the period from 2010 to 2019. The results of Driscoll and Kraay’s (1998) panel regression model show that the leverage ratio is significantly and negatively affected by firm size, profitability, liquidity, asset tangibility, and is positively affected by non-debt tax shields, growth opportunities, earnings volatility, and GDP growth. The pecking order theory seems to be the most successful in explaining the determinants of the capital structure of Turkish textile and apparel firms.

Topografik yükselti ve bakının, Uludağ göknarının ölü örtü, toprak özellikleri, toprak organik karbon (TOK), toplam azot (TA) ve diğer toprak besin elementi (C, N Ca, Mg, P, K, S, Fe, Mn, Na, Cu, Zn, Cl, Ni ve Co) konsantrasyonları ve stoklarına etkilerini belirlemek amaçlı Bursa Uludağ Milli Parkı’nda bir çalışma gerçekleştirilmiştir. Bu amaçla, Uludağ göknarının yayılış yaptığı kuzey (K) ve güney (G) bakıların, beş yükselti kuşağından (Z1: 1400–1500 m, Z2: 1500-1600 m, Z3: 1600–1700 m, Z4: 1700-1800 m, Z5: 1800-1900 m) ve dört toprak derinlik kademesinden (D1: 0–10 cm, D2: 10–20 cm, D3: 20-30 cm, D4: 30-40 cm) ölü örtü ve toprak örnekleri alınmıştır. Sonuçlar genel olarak değerlendirildiğinde, Uludağ göknarı toprak organik karbon ve toplam azot konsantrasyonunun ve stokunun yükseltiye bağlı olarak arttığı ve her bir yükselti kuşağının K bakısında G bakıya göre daha yüksek olduğu belirlenmiştir. Örneğin, TOK stoku, K bakıda yükseltiye bağlı olarak hektarda162 tondan 182 tona, G bakıda ise 116 tonda 176 tona doğru bir artış göstermiştir. TOK stoku, K bakıda G bakıdan %19.7 daha fazla bulunmuştur. Benzer şekilde, TA stokuda, K bakıda yükseltiye bağlı olarak hektarda 9.77 tondan 10.9 tona, G bakıda ise 7.64 tondan 10.1 tona doğru bir artış göstermiştir. Diğer yandan, makro besin elementlerinden Ca, Mg ve P konsantrasyonları ve stoklarında yükseltiye bağlı olarak azalırken, K ve S ise yükselti ile önce bir azalma daha sonra ise bir artış gösterme eğiliminde olduğu belirlenmiştir. Yükseltiye bağlı benzer eğilim mikro besin elementleri içinde tespit edilmiştir. Bununla beraber, genel olarak makro ve mikro besin elementleri her bir yükselti kuşağında, kuzey bakılarda güney bakılardan daha yüksek bulunmuştur. Uludağ göknarının yükselti ve bakıya bağlı değişen ölü örtü ve toprak özelliklerinin (özellikle hacim ağırlığı) yanında mikroiklime bağlı ölü örtü miktarının ve ayrışmasının toprak organik karbon, toplam azot ve diğer makro ve mikro besin elementlerinin konsantrasyon ve stoklarında etkili olabileceği sonucuna varılmıştır.

Published: October 2022

In Hungary, post-war housing estates can be categorised according to the time of their construction. Thanks to the development of construction technologies and urban planning, these so-called generations of housing estates demonstrate different features with regard to their physical layout and socio-economic characteristics. Socio-economic transformation that took place after the change of regime (1989) was widely affected by the physical parameters of these neighbourhoods and their dwelling stock. Our results show that different generations of housing estates have followed distinct trajectories in the housing market; thus, in addition to their geographical location within the city, planning, architecture, design, and the dwelling stock play a significant role in the market positions of these generations of housing estates. House prices have risen rapidly in Budapest since 2014 up until the pandemic in 2020, and housing estates became popular segments of the housing market. The main aim of this article is to investigate the role of urban planning, architecture and the built environment in this real estate process. The research is based on empirical real estate investigations, statistical house price analyses, and fieldwork undertaken on housing estates. The case study area is Csepel, a former industrial town which became the administrative district 21 of Budapest in 1950. All types of post-war generations of housing estates co-exist, and the majority of the population lives in such neighbourhoods. This special geographical context makes it possible to explore the influential role of the built environment in the housing market. Empirical results from these low- and mid-rise housing estates can make a major contribution to the more effective and successful development of high-rise neighbourhoods.
