Abstract
The present research work is focused on the production of aluminum alloy 8011 with 12 wt.-% fly ash composite by using the stir casting method. A three-level central composite design experiment is developed using response surface methodology (RSM) with various parameters. Load, time and sliding velocity are varied in the range of (5-15 N), (5-15 min) and (1.5-4.5 m × s-1), respectively. Dry sliding wear tests are performed as per the experimental design using a pin-on-disc at room temperature. This paper describes how optimization studies were carried out on a dry sliding wear process with multi-response characteristics based on MCDM using the TOPSIS approach. The process parameters, load, time and sliding velocity are optimized with multi-response characteristics, including the wear rate (WR), and the coefficient of friction (COF). A sensitivity analysis is also carried out and compared with the relative impact of input parameters on wear behavior in order to verify the measurement errors on the values of the uncertainty in estimated parameters. The experimental results indicate that the multi-response characteristics of aluminum alloy 8011 with 12 wt.-% fly ash composite used during the wear behavior process can be enhanced through the TOPSIS method.

Abstract
In this study, DAMASK was used to model and elucidate the microstructural deformation behavior of sintered X3CrMnNi16-7-6 TRIP steel. The recently developed TRIP-TWIP material model was used within the DAMASK framework. Material optimization was performed using the least computationally expensive method, which yielded the desired results. The physical parameters of the material model were identified and tuned to fit the experimental observations. This tuned material model was used to run simulations utilizing 2D EBSD data. The local deformation, transformation, and twinning behaviors of the material under quasi-static tensile and compressive loads were analyzed. The results of this are in good agreement with previous experimental observations. The phenomena of dislocation glide, twinning, martensitic transformation, stress evolution, and dislocation pinning in different deformation stages are discussed.
Influence of nanostructured Cu on the mechanical properties of Cu–MWCNTs composites
Authors: Kumar Lailesh , Sahoo Santosh Kumar , Alam Syed Nasimul 
Published: May 2020

Abstract
In the present investigation, Cu-multiwalled carbon nanotubes (MWCNTs) nanocomposites were developed through mechanical milling using nanostructured Cu as a matrix and MWCNTs as nanofillers. The influence of nanostructured Cu on the microstructure, microhardness, and wear behavior of Cu-MWCNTs nanocomposites was also studied. The crystallite size of nanostructured Cu powder via mechanical milling for 25 h was found to be 16 nm. The major challenge associated with the development of Cu-MWCNTs nanocomposites is the uniform dispersion of the CNTs in the Cu matrix, which was addressed by incorporating nanostructured Cu, leading to the homogeneous distribution of CNTs and good bonding between the CNTs and the Cu matrix. A significant improvement in relative density and microhardness with <3 wt.% MWCNTs was observed compared to pure asreceived Cu and its composites. The hardness of Cu-3 wt.% MWCNTs nanocomposite developed using nanostructured Cu were achieved at <800 MPa, which is about 2.3 times higher than that of the as-received Cu sample (~ 359 MPa). The significant increment in mechanical and wear properties mainly originates from fine-grain strengthening effects and solid solution strengthening. The wear mechanisms in the various nanostructured Cu-MWCNTs composites were studied in detail and oxidation wear was identified as one of the main wear mechanisms.

Published: May 2020

Abstract
The effects of the Zn content on the mechanical and corrosion properties of MgZnMnCa alloys were investigated. The results revealed that with increasing Zn content up to 4 wt.%, the Mg-4Zn-0.2Mn-0.2Ca (wt.%) alloy after solution treatment at 400°C for 24 h (ZM40-S) exhibited a volume fraction of 1.56 ± 0.05 (vol.%) of secondary phases with an average grain size of 83.6 ± 1.6 µm. This alloy in the at-cast condition exhibited indentation hardness (Hit) of 657.1 ± 17.8 MPa, which increased to 723.5 ± 29.8 MPa after solution treatments. In addition, the alloy also exhibited a Vickers hardness value of 66.8 ± 2.7 HV and an elastic modulus of 33.8 ± 0.6 GPa, close to the values for human bone. Further, the corrosion properties of this alloy were analyzed: it exhibited a cathodic polarization curve attributed to a hydrogen evolution reaction and an anodic curve corresponding to a passivation tendency, indicating the formation of an oxide layer at the surface; further, its corrosion rate was 0.23 mm/year.

Gerakan Perempuan di Jawa (1912-1941)
Authors: Sujati Budi , Ilfa Harfiatul Haq  
Published: May 2020

Permasalahan Gender di Indonesia dapat dilihat dari aspek ruang dan waktu atas dasar kultur yang berlaku di berbagai tempat dan dalam waktu tertentu. Pada masa itu, kultur budaya Jawa khususnya menempatkan kaum perempuan sebagai kaum yang memiliki hak-hak sosial yang lebih sempit dibandingkan dengan kaum laki-laki di tengah kondisi penjajahan Belanda. Penelitian ini bertujuan untuk melacak jejak langkah gerakan perempuan di Jawa pada masa Pergerakan Nasional. Penelitian ini menggunakan Metode Penelitian Sejarah yang melalui tahapan: Heuristik, Kritik, Interpretasi, dan Historiografi. Gerakan Perempuan mulai melakukan perjuangannya dengan mendirikan sekolah-sekolah, lalu disertai dengan pendirian organisasi-organisasi dan pada perkembangannya menyelenggarakan kongres-kongres. Melalui sarana pendidikan tentunya akan menghasilkan perempuan-perempuan terdidik yang nantinya akan dapat memperjuangkan haknya dengan menuangkan gagasan dan pemikiran, baik secara lisan maupun tulisan.
Conventional and Inverse Magnetocaloric Effect in Ni-Rich Ni-Mn-Ga and Ni-Mn-Sn Heusler Alloy: A Comparison
Authors: Pal D. 
Published: May 2020

Magnetic and magnetocaloric effect of Ni-rich Ni52Mn34Sn14 (Ni-Mn-Sn) and Ni54Mn17Ga29 (Ni-Mn-Ga) Heusler alloys have been investigated up to a magnetic field of 5T and within a temperature range of 4.2 – 325 K. In this study, we report a systematic comparison between Ni-rich Ni52Mn34Sn14 and Ni54Mn17Ga29 alloys in the light of their magnetocaloric effect (MCE). In both the samples, a large magnetic entropy change was observed (~96 J kg-1 K-1 for Ni-Mn-Ga), but for the alloy Ni-Mn-Sn the MCE becomes negative/inverse. From various magnetic measurements it have been observed that in Ni-Mn-Sn alloy the martensite to austenite transition accompanied by lower to higher magnetization whereas for Ni-Mn-Ga alloy reverse situation occurred. The different type of magnetocaloric effect, i.e. inverse and direct can be explained by considering magneto-crystalline anisotropy and different state of magnetization of the martensite and austenite phase of the alloys.

Filhos da Música
Authors: Mion Luciana , Pacheco Reinaldo 
Published: May 2020

A produção e consumo musicais são compreendidos como resultantes de aspectos histórico-sociais e sobre os quais pesam fatores de aptidão e facilidade cognitiva tanto na criação quanto na fruição. Também são reflexo de questões interiores e da identidade do compositor, constituído e constituinte do meio social. A música é uma expressão cultural submetida às forças de mercado e sua dinâmica é de categorização vaga que vai do entretenimento à arte. O artigo aborda o processo do consumo à criação, influenciado pelos hábitos de consumo musical no tempo livre e seus fatores sociais bem como as forças dinâmicas de mercado e de propensão musical. Para tanto, foram apresentados dados de entrevistas com alguns músicos - compositores, quer sejam profissionais ou amadores, pois detecta-se nas entrevistas que a relação entre o trabalho e o tempo livre se mescla para esse público. Como resultado, vimos que o fenômeno da pós-modernidade permeia tal processo e que não há fórmulas para a produção, apenas a verificação de algumas determinantes que se mesclam e são interpretadas e reinterpretadas pelo receptor ativo (compositor), resultando na variação artística.
Developing critical thinking skills to improve reading comprehension
Authors: Rivadeneira-Barreiro María Piedad 
Published: May 2020

The aim of this study is to determine the relationship between critical thinking skills and reading comprehension. Data was collected from treatment sessions, a self-evaluation and a test on critical thinking skills with two groups of learners from a language department at an Ecuadorian university. The results showed insignificant relation between critical thinking skills and learners' reading comprehension. The findings also revealed both groups had small differences during the pretest and posttest. The pretest and posttest showed minimal changes between groups, as well. Participants’ lack of concentration in texts, the unawareness and scarce use of their critical thinking skills were evidenced in their grammar, syntactic and semantics’ mistakes. The implications of these findings suggest further research in this area, exploring teaching practices that foster students’ critical thinking skills and reading comprehension.

Optimización estructural y arquitectónica desde lógicas topológicas a soluciones constructivas de arquitectura en tierra en Pelaya Cesar
Authors: Cadena Gonzalez Innias Miguel , Delgado-Rojas Julio Alfredo , Vergel-Ortega Mawency 
Published: May 2020

La investigación se centra en la problemática actual de los sistemas constructivos basados en acero y concreto con alto valor contaminante que han remplazado en gran medida el uso de materiales vernáculos como la tierra en procesos constructivos, subestimando por completo los factores de sostenibilidad que el material posee. El uso de sistemas sustentable se justifica por la necesidad de nuevos modelos de desarrollo sostenible en la construcción tras la crisis energética de la actualidad, donde a nivel mundial y nacional la tendencia de su uso es positiva pero regionalmente, el Cesar refleja poca apropiación del material, por lo que la investigación presenta como objetivo general el Aplicar lógicas de optimización topológica estructural y arquitectónica a la arquitectura en tierra en el municipio de Pelaya, Cesar, logrando determinar ventajas de las técnicas de arquitectura de tapia y bahareque para optimización topológica, con resultados que sugieren la intervención de estos modelos de diseño para generar sistemas constructivos que respondan a la normativa estructural de construcción colombiana articulados con sistemas constructivos en tierra con alto confort térmico.

Published: May 2020

Este artículo se centra en torno a la construcción de imaginarios y representaciones sobre los docentes por parte de estudiantes universitarios, quienes mediante la metaforización expresan opiniones compartidas sobre el quehacer pedagógico y educativo de sus profesores e incluso sobre su comportamiento en la cotidianidad. Se ofrece además un repertorio de apodos de maestros colocados por jóvenes universitarios, quienes entre otras estrategias semánticas, utilizan la metáfora como eje central para nombrar a sus profesores.
El texto comprende además elementos de tipo descriptivo y explicativo acerca de la acción de apodar en un contexto académico. Asimismo se destacan los recursos sintácticos y semánticos de los que se vale el estudiante apodador para crear el nuevo nombre y se habla de las motivaciones y características del apodo en su proceso de formación, un tema novedoso e interesante en el ámbito de la investigación educativa. La investigación es sociodialectal, pues se aborda una parte de la lengua y se intenta establecer relaciones entre lo lingüístico y lo sociocultural. Para ello se recopiló un corpus de 700 apodos a través de encuestas y entrevistas realizadas a 2000 estudiantes entre 16 y 35 años.
