Authors: Alidmat Mohammad Murwih , Khairuddean Melati , Salhimi Salizawati Muhamad , Al-Amin Mohammad
Published: May 2021

Introduction: A bis-chalcones were prepared by the reaction of terephthalaldehyde with 3-acetyl-2,5-dichlorothiophene or 3-acetyl- 5-chlorothiophene and reaction cyclo ketone derivatives with phenyl aldehyde derivatives in good yields.

Methods: The molecular docking studies were conducted using the Discovery Studio (DSv4.5) and MG. Tools installed in Window 10. The cancer receptor (3ERT) was downloaded from the protein data bank (PDB). All new compounds were characterized by IR, 1H-NMR, 13C-NMR, 2D-NMR, and CHN elemental analysis. The anticancer activity of the synthesized compounds was determined using MTT (3-(4, 5- dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) reduction assay against MCF-7 cells, and then the minimum inhibitory concentration (IC50) was determined with the reference of the standard drug tamoxifen.

Results: The results showed that compound 6 showed more potent activity in inhibiting growth on both types of MCF-7 compared to reference tamoxifen.

Authors: Sy Hoang Van , Toan Dang Quang , Huong Ta Thi-Thanh , Hoa Chau Ngoc , Trang Tran Kim
Published: May 2021

Background: Several studies have investigated Galectin-3 as a promising biomarker for predicting the short-term and long-term mortality of patients with acute heart failure. This study aimed to examine the usefulness of plasma galectin-3 at the time of admission in predicting long-term mortality in Vietnamese patients with acute heart failure (AHF).
Methods: We carried out a cohort study including 117 patients consecutively diagnosed with acute heart failure in a single cardiology department. Plasma galectin-3 and other biomarkers were measured at the time of admission. The patient’s clinical and analytical characteristics were recorded. The main endpoint was one-year all-cause mortality.
Results: There were six patients (5%) lost to follow-up and 59 patients (53.2%) reaching primary outcome within one year after ‎hospital admission.‎ The median plasma galectin-3 level (ng/mL) in patients with acute heart failure was 34.6 (26.7 – 44.1). Plasma galectin-3 in the alive group was significantly higher than that in the deceased group at one-year follow-up. In predicting one-year all-cause mortality, galectin-3 had an area under the curve (AUC) of 0.71 (95% confidence interval (CI), 0.62 – 0.81) representing a good prognostic factor while brain natriuretic peptide (BNP) and troponin I were inferior to galectin-3 with an AUC of 0.69 (95% CI, 0.59 – 0.79) and 0.63 (95% CI, 0.53 – 0.74), respectively. The optimal cut-off value for galectin-3 was 40.75 ng/mL with a sensitivity of 50.1% and a specificity of 88.5%. In a multivariate model, patients with galectin-3 levels > 40.75 ng/mL had a hazard ratio (HR) of 2.8 (95% CI, 1.5 – 5; p = 0.001). The best prediction model was the combined model of galectin-3 and BNP, yielding an AUC of 0.78 (95% CI, 0.70 – 0.86; p < 0.001).
Conclusions: Our study suggested that galectin-3 levels could predict long-term all-cause mortality in patients with acute heart failure with a good prognostic capacity. Combining galectin-3 and BNP could bring up a better risk-stratification.

Published: May 2021

Introduction: Mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) have a potential role in improving wound healing processes. This experimental study aims to compare PRP and MSCs to promote the wound healing process in the animal burn wound model.

Methods: PRP from venous blood and MSCs from lipoaspirates were isolated from six donors. Saline solution was used as control while PRP and MSCs as treatment groups were injected to second-degree burn wounds in the backs of 10 male Sprague-Dawley rats for each group. On day 7, 5 rats from each group were euthanized for analyses VEGF gene, which has a role in angiogenesis. At the end of the study (week 5), the remaining rats were euthanized for histological analysis.

Results: The VEGF expression in MSCs and PRP groups was higher than the control group (not significant). The wound healing rate was also significantly faster until 21 days post-burn in the MSCs and PRP groups and getting slowly afterward. Histological analysis showed the burned skin at day 35 had displayed the best differentiation outcome in the MSCs group. In conclusion, human-derived MSCs and PRP do not accelerate epithelialization duration of rats burn wound model. However, they improved wound’s vascularization and cell differentiation.

Conclusion: MSCs are superior to PRP in enhancing cell differentiation.
Present Status of Research on the Regenerative Potential of Dental Pulp Stem Cells in Malaysia: A Systematic Review
Authors: Haque Nazmul
Published: May 2021

Stem cells from human exfoliated deciduous teeth (SHED) or dental pulp stem cells (DPSCs) from permanent teeth are considered promising sources of mesenchymal stem cells. It requires a less invasive technique to isolate stem cells from exfoliated or permanent teeth. Hence this study aimed to identify the present status of research on the regenerative potential of SHED/DPSCs in Malaysia. The results indicate that only 60 articles were published in regenerative medicine from Malaysia till 5th July 2019. Only 16 tertiary institutes and four industries/clinics were involved in these studies. A poor pattern of collaboration has also been identified. Outcomes of this study have emphasized the conduction of more research on the regenerative potential of SHED/DPSCs, and active collaboration among the tertiary institutes and industries for successful translation of these cells from bench side to bedside.
Master of TESOL students’ conceptions of assessment: questioning beliefs
Authors: Martínez Marín Juan Diego , Mejía Vélez Maria Camila
Published: May 2021

The current descriptive study investigates the conceptions of a group students (pre-service and in-service teachers) enrolled in a Master of TESOL (Teaching English to Speakers of Other Languages) at La Trobe University, Australia, have of assessment in the context of English language teaching. This study was conducted in first place to address a gap in the literature about English teachers’ conceptions of assessment, and I second place to explore the level of agreement among those conceptions and the type of assessment preferred by the participants. For this purpose, 26 active students in the course accepted the invitation to participate in the study and completed an online survey administered through Qualtrics Management Platform. This quantitative descriptive study done in 2020 used Survey as the research method since it promotes the collection of data to describe the research object. The quantitative data obtained through an online survey were summarized and graphed in tables with the objective of answering the research questions. The results showed that participants’ understandings of assessment and forms of assessment were slightly inclined towards the use of summative assessment rather than formative. In contrast, their conceptions of assessment purposes and principles were inclined towards formative assessment features. All in all, it could be said that even though these participants seemed to cope more with summative assessment, they favoured formative purposes and principles of assessment. This suggests that respondents’ summative views of assessment in the use of types and forms of assessment are potentially affected by institutional demands, and do not entirely reflect the respondents’ assessment understandings.
Procesos reflexivos, desde las artes, sobre problemáticas de género en una escuela primaria de Santiago, Chile
Authors: Montenegro-González Catalina , Fierro-Navarro Natalya , Tardón-Gangas Natalia
Published: May 2021

El presente artículo visibiliza el proceso de investigación e intervención en una escuela de la comuna de Santiago de Chile, a partir de dos unidades didácticas de Artes Visuales en sexto grado, donde se incorporaron problemáticas de género, como violencia y estereotipos. El objetivo de la investigación fue rediseñar, contextualizar y realizar intervenciones escolares en la asignatura de Artes Visuales, vinculadas a problemáticas de género presentes en los espacios cotidianos del estudiantado. La metodología de la investigación desarrollada durante 2018 y 2019 es una investigación-acción participativa. Los datos fueron recabados a través de la propia práctica docente y los instrumentos de evaluación dentro del aula (diagnósticos, círculos de conversación, trabajo artístico-creativo y presentación). La propuesta didáctica investigativa nos muestra la importancia de la integración de la reflexión en la creación artística, al lograr el objetivo propuesto. De esta manera, se abrió el espacio de debate sobre situaciones de violencia, la necesidad de valorar las experiencias personales vinculadas a temáticas de género, el respeto por la diversidad y la necesidad de construir aulas más inclusivas y respetuosas de la diversidad sexual y del género. Lo anterior da como principales resultados el desarrollo de una actividad artístico-reflexiva, el cuestionamiento de los estereotipos y las dinámicas sociales, además de propiciar el trabajo artístico-colaborativo como espacio de discusión, confianza y creatividad, dando relevancia al proceso por sobre los resultados, aspectos que perduraron en el grupo de estudiantes más allá de la asignatura de Artes Visuales.
Subjetividades juveniles y narrativas escolares en el Telebachillerato Comunitario en México
Authors: Salgado Escobar Rocío Elizabeth
Published: May 2021

En México, la obligatoriedad de la Educación Media Superior decretada en 2012 todavía es tarea pendiente en los contextos rurales y conurbados en donde los Telebachilleratos Comunitarios son una política educativa en expansión para incorporar jóvenes antes excluidos del sistema escolar. El Telebachillerato tiene sus orígenes en 1980, no obstante, la modalidad escolarizada y comunitaria cuenta con apenas cinco generaciones, y aún es escasa la investigación desde la perspectiva de sus propios actores. Por esta razón, el presente estudio se propuso comprender cómo las condiciones de acceso a este tipo educativo signan las subjetividades juveniles y su experiencia escolar. El estudio de corte cualitativo-interpretativo se desarrolló al sur del estado de México, durante el bienio noviembre 2018-2020, bajo una metodología dialógico-reflexiva desplegada en un taller de narrativa con un grupo de sexto semestre. Las sesiones fueron videograbadas, transcritas y sistematizadas en tres líneas analíticas: condiciones de acceso a la escolaridad, subjetividades juveniles y participación en la escuela. Los resultados visibilizan itinerarios escolares marcados por la implementación precaria de una modalidad en donde la población de jóvenes se enuncia a sí misma como la más abatida, pero en la que también construye otros modos de subjetividad a través de la participación para demandar mejor infraestructura, incidencia en la normatividad escolar y procesos pedagógicos basados en el reconocimiento. Se concluye que las subjetividades y narrativas escolares son fundantes de comunidades educativas construidas en el diálogo reflexivo y emergentes sentidos juveniles que se ponen en juego en el ejercicio del derecho a la educación.
The Costa Rican business sector’s concepts of the transfer of German dual training
Authors: Láscarez-Smith Daniel , Schmees Johannes K.
Published: May 2021

This article analyzes the tripartite social dialogue of an inter-institutional commission in Costa Rica, which took place from February 27 to September 1, 2017. During this time the Costa Rican state the business sector and unions discussed ways to implement dual vocational education and training (VET) in Costa Rica, using the German model as a reference. Here, the focus is on the business sector’s concepts regarding if and how the German dual VET model should be transferred to Costa Rica. the findings are based on two interviews with Costa Rican business representatives and the observation of dialogue table meetings with representatives from the state, the business sector and unions. Based on the premise that discourses express and influence social practices, it is analyzed how the structure of the business sector’s arguments relate to Toulmin’s model of argumentation. It is concluded that from the Costa Rican business sector’s point of view, the policy of dual education in VET is essential to gain economic strength in a global market. However, for these business groups, the model must be “tropicalized” in a way that redefines some of the bases of the German reference model, such as union participation, distribution of training costs as well as the legal status of the apprentice. Therefore, it is concluded that the discussion on the dual model of VET was used as a window of opportunity to promote reforms that would favor the business sector.
Incidencia de la Estrategia para la Gestión del Riesgo en Escuelas de Santo Domingo de Heredia, Costa Rica

Published: May 2021

La Estrategia para la Gestión del Riesgo de Desastre en el Sector Educación de la República de Costa Rica cuenta con abundantes metas y resultados para mejorar el manejo del riesgo en las comunidades educativas, pero su incidencia en el sector escolar de Santo Domingo de Heredia, Costa Rica, no ha sido evaluada todavía. Ese plan fue creado en el 2014 pero aún no hay una medición de su influencia en la capacitación de docentes del área estudiada. El objetivo de la publicación es informar sobre el papel del planteamiento en el manejo del riesgo en 8 escuelas de Santo Domingo. La investigación, cualitativa y básica, se centró en los resultados propuestos por la Estrategia y fue realizada entre 2018 y 2019. Para obtener la información requerida, el grupo investigador solicitó datos a la persona que enseña gestión de riesgos y a la que coordina el comité de gestión de riesgos en cada uno de las escuelas seleccionadas. Ello requirió cuestionarios con preguntas de respuesta corta alusivas a los productos de la Estrategia esperados al 2020. El grupo investigador encontró que algunas personas docentes han sido capacitadas, pero son pocas con respecto a las metas propuestas, y los cursos realizados son más de atención de emergencias que de prevención del riesgo. Los resultados indican que el plan se está usando, pero su incidencia es poca en el manejo de los riesgos en las escuelas de Santo Domingo. Tal conclusión implica que se debe incrementar esfuerzos para que la Estrategia genere los resultados esperados.
A comparative study on the two vibration driven locomotion systems in various friction levels
Authors: La Ngoc-Tuan , Nguyen Thanh-Toan , Nguyen Van-Du
Published: May 2021

This paper presented comparison results of two locomotion models: a pure-vibration driven and a vibro-impact driven system. In experiments, the friction force can be varied without changing the internal and the body masses. The mathematical models of the two systems were developed and experimentally verified. Using dimensionless models, the results can be expanded to other sizes in practice. The two models were compared in the following aspects: the progression rate, the motion direction and the dynamics response. The effect of friction as an important variable on the dynamic response of the two scaled models were examined and compared by means of bifurcation analysis and basin of attraction. It has been found that, the pure-vibration can provide forward motion better than the vibro-impact does. The highest progression rate of the vibro-impact was less than that of the pure-vibration system in the investigated ranges of input parameters. Besides, the pure-vibration always has period-1 motion, whereas the vibro-impact system has a rich and complex dynamic response, including period-1, period-2 as well as chaotic motions. The results obtained would be useful for design and operating the self-propelled locomotion systems.
Os estudos do futebol na Inglaterra
Authors: Hollanda Bernardo Borges Buarque de
Published: May 2021

O artigo apresenta o debate bibliográfico sobre os estudos futebolísticos na Inglaterra, delineando as principais vertentes de análise e interpretação da violência no esporte, fenômeno comportamental associado ao profissionalismo esportivo na segunda metade do século XX. Visa-se expor as matrizes mais importantes de pensamento – autores, obras e instituições – que se debruçaram sobre o comportamento de grupos de torcedores, dentro e fora dos estádios daquele país, entre as décadas de 1960 e o início dos anos 2000. Sustenta-se que a chamada Escola de Leicester, reunida ao redor da figura de Norbert Elias, em especial seu discípulo Eric Dunning, foi capaz de desenvolver o mais extenso referencial teórico de explicação histórico-sociológica para as brigas intergrupais e a sua “busca da excitação”, decorrente das rixas e das emulações entre adeptos de diferentes clubes ingleses. De forma contemporânea aos acontecimentos que procura analisar, entende-se que o subcampo de estudos intitulado “hooliganismo” na Grã-Bretanha é tributário da hegemonia interpretativa eliasiana e balizou a leitura dos sentidos de um “processo civilizador” entre o público seguidor dos esportes modernos, com ênfase a seus períodos conjunturais de “descivilização”. É desse modo que se opera um “antes”, isto é, as correntes que trouxeram as primeiras análises para a explicação da violência hooligan no futebol até os anos 1970, e um “depois”, ou seja, os pesquisadores que a partir dos anos 1990 procuraram rever os paradigmas da Leicester School e, no limite, formularam uma crítica a seus pressupostos, a fim de superá-los.
Tópicas nos trópicos
Authors: Felipe Cleber Vinicius do Amaral
Published: May 2021

Este texto volta-se para um conjunto de lugares-comuns presentes no romance O Guarani (1857), de José de Alencar. Para tanto, buscamos historicizar o paradigma artístico que subsidiou sua escrita, analisar a construção do éthos indígena e mapear algumas figuras mobilizadas para descrever as florestas brasileiras e o cataclismo que encerra a narrativa. Nossa proposta atém-se a uma abordagem estética que não negligencia o caráter datado dos códigos linguísticos, ou seja, tópicas como originalidade e genialidade foram tomadas como convenções ou constructos que o romance alencariano buscou dissimular para atender aos protocolos literários de sua época. Embora seja recorrente a negação dos artifícios retórico-poéticos, o romancista recorreu a novos recursos como, por exemplo, à concepção de sublime. Não há, portanto, ausência de protocolos e prescrições, mas a eleição de outros expedientes letrados articulados às propostas políticas de D. Pedro II, ao projeto indianista e às novas demandas estéticas.
História, república e fundação da cidade de Florença em Coluccio Salutati, Leonardo Bruni e Maquiavel
Authors: Magalhães Pinto Fabrina , Falcão Luís
Published: May 2021

O artigo argumenta que a historiografia humanista e renascentista sobre as origens de Florença produziu, paulatinamente, rupturas com a visão medieval da fundação da cidade pelo Império Romano. Com Salutati, há a primeira declarada defesa da fundação pela República Romana, sustentada em monumentos históricos e textos antigos. Bruni acrescenta o fato de que, por legítima herdeira, Florença recepciona ainda a responsabilidade de levar glória e grandeza às demais províncias da península. Malgrado o contexto de guerra com Milão ser importantíssimo nas explicações dos textos desses humanistas, a continuidade do tema com Maquiavel prova que ele sobreviveu pela sua força teórica, ainda pouco explorada pela bibliografia especializada. Para ele, não se trata apenas de ligar as origens de uma cidade ao seu prestígio e função na contemporaneidade, mas o tema da fundação em si mesmo exige uma reflexão teórica. O artigo apresenta esses marcos atento às inflexões e, sobretudo, aos aspectos teóricos de composição historiográfica.
O problema da forma
Authors: Farias Damião
Published: May 2021

O artigo problematiza o tema da forma na obra Raízes do Brasil, edição de 1936. Para realizar a interpretação, buscamos aporte em autores que tiveram confluências com o modernismo no Brasil e em outros países. Assim trabalhamos, sobretudo, com Nietzsche. Acreditamos ter alcançado êxito em demonstrar os vínculos das abordagens de Holanda em direções estético-expressivas sobre os ajustamentos e dissonâncias entre forma e conteúdo, cultura e Estado na história brasileira, nos períodos do Império e República. Holanda perscrutou os tempos brasileiros e divisou o distanciamento progressivo das formas políticas liberais em relação aos valores culturais do personalismo que caracterizaram a nossa história. Sua proposição é, ainda que difícil de ser vislumbrada, a favor de nova configuração da política em termos congênitos à específica cultura nacional, com o objetivo de melhor expressar os valores personalistas, em regime oligárquico/aristocrático, o que supostamente abriria a história brasileira para a criação de novas possibilidades.
The Analytical Metaphysics of Time and the Recent Theory of History
Authors: Cardoso Jr. Hélio Rebello
Published: May 2021

The longstanding line of research that the analytic tradition calls metaphysics of time remains quite ignored by the theory of history.  To bring them closer, this study proposes to introduce to historians and theorists of history the metaphysics of time theses about the presentism/eternalism and the linear/closed time. For such purpose, we drew correspondences between the theory of history and the analytical metaphysics of time concerning some characteristics of the emerging concepts of historical time. These characteristics are related to the recent debate about presentism regarding the regimes of the historical time (multiple temporalities and pluritemporality); plural time in the analytical metaphysics and synchronous/asynchronous historical time; linear/closed time in the analytic tradition and being affected by historical time. As a result, this article presents how the analytical metaphysics of time theses disclose unnoticed contours related to the history theorists’ understanding about the relation with the past.
What the eyes can’t see
Authors: Medeiros Bruno Franco
Published: May 2021

Over the last years, Monteiro Lobato has been rightfully accused by Brazilian and Latin American scholars of expressing racist and eugenic ideas in his body of work. In this article, we take a step further and add to this traditional portrait of his literary production an analysis of the impact of a new set of technological media during the first decades of the twentieth century on his writings. We discuss how these two main issues – i.e., technology and race – played out in Lobato’s historical representation of Brazil’s past and future and the influence that the United States could play in it. We show how a revisionary and racist version of the United States’ history and the ideal of an American technological prosperity in the 1920s inspired one of Lobato’s most contentious novels, the technological dystopia O Presidente Negro, ou O Choque das Raças, published in 1926.
Hernandez Arregui y la invención de una historiografía para la izquierda peronista
Authors: Caruso Valeria A.
Published: May 2021

Este trabajo tiene por objeto analizar el proceso de configuración de una historiografía de la izquierda peronista, luego de 1955, observable en las intervenciones intelectuales realizadas por Juan José Hernández Arregui por medio de su ensayística histórica. En primer lugar, se exploran las condiciones de posibilidad que intervinieron en el proceso de emergencia de esa ensayística histórica, así como sus características. En segundo término, se analizan las acciones desplegadas por este intelectual para difundir y legitimar su concepción sobre el pasado nacional y el peronismo. Esta indagación sostiene que las luchas por la vigencia del peronismo durante el periodo en el que esa fuerza política estuvo proscripta fueron constitutivas de las formas que ensayó Hernández Arregui para abordar el pasado argentino.
Sérgio Buarque de Holanda e Gilberto Freyre
Authors: Sanches Dalton
Published: May 2021

Propomos que a segunda edição de Raízes do Brasil (1936), publicada em 1948, representa o epítome da guinada negativa de Sérgio Buarque de Holanda quanto ao seu companheiro de geração Gilberto Freyre. As modificações incisivas nessa edição do clássico livro não podem ser, em parte, compreendidas sem que se leve em conta o constrangimento da influência exercida por Casa-grande & Senzala (1933), bem como os mecanismos de consagração apropriados por Holanda no âmbito das instituições, a partir de finais da década de 1940. Para tanto, além das duas primeiras edições de Raízes do Brasil e do clássico de Freyre, lançaremos mão de alguns escritos anteriores e posteriores a esse marco, 1948, a fim de apresentar a historicidade dessa interlocução, que vai da competição literária à disputa pela interpretação do Brasil; perpassa por questões epistemológicas, dentre essas a forma ensaio; e toca as desavenças constituintes das batalhas simbólicas no campo intelectual, a partir das quais anatematiza-se o nome do pernambucano do ensaio revisado.

The corundum is found in the rocks of the Berit metaophiolite in Eastern Anatolia, near Doğanşehir a province of Malatya. Metaophiolitic rocks consist mainly of garnet metagabbro, granulite, amphibolite, mylonitic amphibolite, garnet amphibolite, amphibole schist, pyroxenite, mylonitic pyroxenite, orthopyroxenite, harzburgite, serpentinized dunite and diorite units. Corundum occurrences are mostly found in pyroxenites, amphibolites, peridotites and granulites. Their colors change in range between reddish pink, pink and light pink. They are usually in structure of translucent, vitreous and sometimes cracked. They are seen scattered or clustered together inside the rocks in which they are found. The size of their crystals ranges from 0.5 cm to 10 cm and their euhedral crystals are observed in pseudohexagonal form. As a result of the petrographic examinations, it was observed that pyroxene, amphibole, garnet and plagioclase minerals accompanied with the corundum. The samples of the rocks containing the corundum has qualifications which will be as an object of gemstone and ornament by means of cutting and shining. Large specimens of corundum can be processed alone. Samples, being as scattered and small granules inside the rock can be processed together with the host rock. In the processed samples, it was obtained patterns like the samples of corundum with zoisite which were in great demand in the world gemstone market.
Evaluation of Urban Images: The Case of Adana
Authors: ŞENYİĞİT Özlem , ATAY Gamze
Published: May 2021

The image is a formation of momentary perceptions, past experiences, and memories. From this point of view, the perception of images is not merely visual; it has sociology and history that it represents. In this context, the city of Adana, which has a multicultural history of 8000 years, hosts a wide variety of elements in terms of architectural imagery depending on its historical background, industrialization, and development process. In the study, the historical and new architectural images on the banks of the Seyhan River, which is an important historical, economic and sociological region of the city, were examined with an aim to question how the images related to Adana were interpreted by the public. In line with this objective, the data obtained from photo archives, survey techniques, and the results of statistical analysis performed using the SPSS software package were analyzed together to question the architectural image components. Within this framework, conducted with 60 individuals, the followings were questioned and answers were sought for the city users:
- Primary images of the city,
- The reasons that have created the images, in other words, the values that have been effective in transforming these buildings into images,
- The reasons for the differentiation of the selected historical and new images in their imagery values. The results of the statistical analyses revealed that the urban element/building that has not been utilized actively could not establish the relationship of belonging with urbanites, therefore, the building's imaginative effect has been weakened, and particularly the historical buildings have been the most influential factors that make up the imaginative value due to their traces in urban memory. Therefore, the present study and similar studies on retaining urbanites' relationship with the residential areas are considered valuable in terms of both shedding light on future studies and using them as data in the practices.
Smart Touch Voltage Limitation
Authors: TURHAN Mahmut
Published: May 2021

In modern railway electric infrastructure design there are two major concerns that should be considered as touch voltage and stray current. The first problem is touch and step voltage which endangers human safety even to deathly situations. Second problem is stray current which leads to corrosion of metallic infrastructure. Since human safety has higher priority early on railway systems has grounded the rail voltage to the earth but this caused stray current problem. Thus these two problems should be handled together. In this paper we present a touch voltage control and stray current monitoring solution to handle both problems. Our solution presented here uses thyristor based grounding to limit touch voltage and monitor and report stray current

The metal skin at air vehicles provide an important shielding effectiveness against the effects of high amplitude electromagnetic waves. In recent years, the composite materials with the advantages such as being lighter, causing lower fuel consumption, are used as a replacement of metals. In this paper, electromagnetic shielding performance of composite materials in air vehicle manufacturing industry is investigated. A panel model is used to obtain the shielding performance of these composite materials. Due to the geometrical similarity of air vehicles with a cylinder, a cylindrical shell model is also considered. Analytical calculations for the interaction of an electromagnetic pulse(EMP) with composite materials are carried out for both panel and cylindrical models. Also, the panel and cylindrical models are constructed via Computer Software Technology(CST) program and analytical and simulation results are compared. There is a good agreement with the results.

Tall buildings have the ability to produce wind energy, having been exposed to relatively high airflow speeds at a far distance from ground levels. However, with the introduction of wind energy into urban areas, there are many concerns. These include especially environmental noise impacts since the wind turbines will be located in dense urban areas where tall buildings are mostly located. Therefore, this increasing use of wind energy in the built environment has led to the publication of up-to-date regulations that limit noise levels for wind farms in many European countries. At this point, the following three aspects should be considered for noise emission: the noise source, the distance from the source, and the sound pressure level of the noise source. The choice of wind turbines for urban environments should, therefore, be compatible with low noise levels. In addition, careful positioning of turbines is also important (avoid locations where wind conditions are unfavorable, avoid sensitive places, i.e. areas at which noise levels must be low). It was necessary to calculate the noise in strong winds because the noise from a wind turbine rises with wind velocity. For the measurement of noise emitted from the wind turbine, two potential solutions were proposed until now; either it could be measured in a wind tunnel or it could be measured in the natural wind outside. However, in the early design stage, these types of measurement methods are mostly not preferable due to high financial requirements and long measurement processes. Hence, in this study, wind turbine noise is simulated via software. A case study of a tall mixed-use tower is chosen and the environmental noise distribution due to the wind turbine located on the roof of the tower is simulated. The results may provide an important guideline for architects looking for an acoustically comfortable way to integrate wind turbines into their buildings in the early design stage.

High concentrations of the ambient particulate matter remains a concern on the South African Highveld, particularly in densely populated low-income settlements. These areas have several local emission sources that contribute to poor air quality and are often located close to industrial and other urban areas. The local sources vary in magnitude, space, and time. In South Africa, little has been done to assess the impacts of spatiotemporal variability on the credibility of using isolated ambient observations for regulatory purposes. This study aims to evaluate the intra-urban variability of ambient PM2.5 concentrations in a dense, low-income community. Ambient fine particulate matter (PM2.5) in distinct microenvironments of KwaZamokuhle were simultaneously measured at 4 sites between March and June 2018. These measurements were collected using one permanent ambient monitoring station (AMS) and a temporary network of three E-BAM monitors (Site 2, Site 3, and Site 4). The daily PM2.5 concentrations at AMS, Site 2, Site 3, and Site 4 varied from 10 to 86 µg.m-3, 10 to 103 µg.m-3, 11 to 101 µg.m-3, and 9 to 113 µg.m-3, respectively. Extreme PM2.5 concentrations which exceeded the 24h PM2.5 NAAQS of 40 µg.m-3 were seen during the cold period (May and June); meanwhile, the warm period (March and April) recorded relatively lower PM2.5 episodes across different sections of KwaZamokuhle. During May-June, the highest diurnal concentrations of hourly averaged ambient PM2.5 were recorded at Site 4, in a downward sequence, followed by Site 3, Site 2, and AMS. Furthermore, the results showed that across KwaZamokuhle, Site 4 has the highest proportion of households using solid fuels for domestic purposes (cooking and heating) (55%) and the number of informal dwellings (117 households). Therefore, the study highlights the complexity of quantifying ambient air quality in an area where several local emission sources vary in space and time. Attempts to use monitoring data from a single station to assess ambient air quality, quantify human exposure, or evaluate the potential impacts of mitigation strategies in dense, low-income settlements should be done with care.
Alienation and estrangement in Dinaw Mengestu’s All Our Names
Authors: Openda Ruth Kwamboka
Published: May 2021

In this article I explore issues of negotiating cultural identity in new geopolitical spaces as presented in Dinaw Mengestu’s All Our Names. I examine the portrayal of a liminal character living in Uganda and America and how the author narrates his daily experiences of negotiating identity in order to underscore the power of hierarchies of ethnicity, class, race, and nationalistic discourses at play in determining who belongs and who does not. I analyse the ways in which names are used as narrative strategy to show that identity is never singular or fixed but plural and continuous. I explore how, through Isaac’s unnaming, naming, and renaming, Mengestu contests the fixity of names and identity by indicating naming as a processual act and how a person’s identity is layered and thus cannot be fully contained within a single marker. Drawing upon the concepts of hybridity, third space, and cosmopolitanism, I demonstrate how subject position and cultural identity are not fixed into definite categorical distinctions but are fluid concepts. Mengestu does not only raise possibilities of belonging beyond the confines of a nation or community, but also presents a cosmopolitan world where negotiation and belonging is difficult because of power differences, racism, marginalisation, and discrimination.

Background: Hypoxic ischemic encephalopathy is a serious concern among asphyxiated newbornsdue to the associated long term sequelae like cognitive impairment and cerebral palsy. Though theincidence of hypoxic injury remains higher in preterm babies due to incomplete brain maturation, itcan occur in term babies as well despite institutional deliveries due to an array of unavoidable fetal,maternal and placental causes. Aims: This study was conducted as an attempt to evaluate the riskfactors, to study the correlation between the term of pregnancy with TCUS and MRI imaging findingsin HIE and characterise patterns of CNS involvement. Materials and methods: It was a cross-sectional study carried on 50 neonates with clinically diagnosed HIE presenting to the Department ofRadiodiagnosis, Rajindra Hospital Patiala who were subjected to transcranial sonography and MRI.Results and Conclusion: This study demonstrated term infants have significant involvement ofbasal ganglia thalamus type (central) pattern of involvement and preterm infants haveperiventricular leukomalacia type (white matter injury) of a pattern of involvement. The overallsensitivity and specificity of TCUS in detecting imaging findings in children with clinically diagnosedHIE compared to MRI was found to be 70.45% and 50% respectively, yielding the overall diagnosticaccuracy of TCUS as 68% compared to MRI. TCUS can depict central and white matter abnormalitiesbetter than peripheral lesions. However MRI provides additional diagnostic information in manycases and can detect precisely the extent of brain injury.

AbstractAdult laryngeal hemangiomas (ALH) are clearly defined, with a bluish red color, appearing most often in the glottic and supraglottic region. The principal symptoms are hoarseness, occasional hemoptysis, and in advanced cases, dysphagia and difficulty in breathing. The patient was a 55 year old female suffering from hoarseness for a long time, experiencing shortness of breath for the last 1 year and she was referred to our clinic from the emergency department due to stridor. In the endoscopic examination of the patient, both vocal cords were found to be mobile, and a blue-purple mass lesion was detected, which was filling the subglottic region and allowing air passage only in the posterior part. Emergent tracheotomy was performed for the airway safety. The mass located in the subglottic region was approached with the Laryngofissure technique and was excised. Surgical management is necessary when ALHs became symptomatic for hemorrhagic or infectious complications, or for progressive airway obstruction. In this paper, we present the clinical and radiological features of a large subglottic ALH.
