Avaliando o impacto do uso de super-heróis no ensino de ciências sobre a motivação intrínseca de estudantes no ensino básico.
Authors: Miranda Lucas Mascarenhas de
Published: September 2020

Este relato de experiência visa apresentar a aplicação de um projeto para o ensino de ciências em um colégio da rede privada de Juiz de Fora (Minas Gerais), que consiste em utilizar discussões sobre super-heróis e seus superpoderes, bem como outros elementos da cultura pop, para dar mais sentido ao estudo das ciências e propiciar visões mais críticas sobre a figura do cientista e o fazer científico. Para tanto, elaborei onze atividades diferentes, fundamentadas em textos previamente publicados no blog de divulgação científica Ciência Nerd, e conduzi discussões sobre a ciência presente em determinados filmes, séries e quadrinhos em três diferentes turmas de ensino fundamental e médio. Através da observação destas discussões e da análise de resenhas críticas produzidas posteriormente pelos alunos, avaliei o potencial do uso destas temáticas no aumento da motivação intrínseca dos alunos. Os resultados sugerem um aumento substancial nos estudantes: da autonomia, da autodeterminação, da motivação intrínseca, da percepção sobre o caráter interdisciplinar da ciência e do senso de pertencimento à ciência. Concluo com este relato que o potencial desta ferramenta ficou evidente, justificando a necessidade de estudos futuros a esse respeito.
Utilização e implicações dos antimicrobianos: a percepção de professores em formação
Authors: Menezes Jones Baroni Ferreira de , Melo Eliane Dos Santos , Oliveira Josilene Ferreira
Published: September 2020

Antibióticos são medicamentos com a finalidade de matar bactérias ou inibir seu crescimento. Representam claramente um dos maiores avanços na medicina, porém o uso indiscriminado e abusivo dessa classe de fármaco contribuiu para o grande problema de saúde pública, a resistência bacteriana. Nessa perspectiva, essa pesquisa foi proposta com o objetivo de compreender os saberes de licenciandos em Ciências Biológicas sobre uso e problemáticas dos medicamentos antimicrobianos. A pesquisa caracteriza-se como um estudo de caso descritivo e longitudinal, de abordagem quantitativa. Os dados foram coletados por meio da aplicação de um questionário a 33 discentes do nono semestre do curso de licenciatura em Ciências Biológicas da Faculdade de Educação de Crateús (FAEC), no qual se abordou o conhecimento a respeito dos antibióticos e seu uso, sobre resistência bacteriana, e os conhecimentos adquiridos no decorrer do curso. De acordo com os resultados, constatou-se que 67% demostram um conhecimento adequado a respeito do conceito de antibióticos. Sobre a resistência bacteriana, todos os alunos compreendem sua conceituação e problemática. Ademais, a maioria dos discentes afirmaram fazer uso incorreto desses fármacos, utilizando de forma errônea ou por automedicação. Portanto, esse tema precisa ser mais abordado nas aulas levando ao conhecimento satisfatório, tanto para práticas de uso individual como para que a aprendizagem seja transmitida de forma eficiente para os estudantes.

Published: September 2020

As pesquisas na área da educação superior e de gênero sobre carreiras das ciências exatas, ainda são recentes no Brasil. As mulheres, apesar de terem conquistado lugar em profissões ditas “masculinas”, esses espaços não são amigáveis. Elas entraram em massa nas universidades, mas não necessariamente como professoras, até mesmo no serviço público, onde já não existem barreiras ao ingresso das mulheres, sua ascensão nos ambientes “masculinos” ainda encontra muitos obstáculos. Este artigo apresenta reflexões sobre a carreira de uma professora do departamento de Física de uma universidade federal, a partir de sua narrativa biográfica. A investigação partiu da seguinte questão norteadora: as relações de gênero afetam a carreira de uma docente do curso de Física? O principal objetivo foi identificar a percepção da discriminação de sexo e gênero na relação entre colegas de trabalho no departamento de Física de uma IFES do nordeste brasileiro, sob o ponto de vista de uma das docentes. O embasamento teórico foi pautado nas discussões sobre as relações de gênero e a divisão sexual do trabalho, considerando a cultura e o campo acadêmico. A técnica de coleta de dados empregada foi a de entrevista narrativa biográfica, e foi realizado um ciclo de três entrevistas. Os dados foram analisados, a partir da construção da (auto) biografia, utilizando a análise do discurso. Nos resultados foi possível identificar que as relações de gênero interferiram na trajetória profissional da docente biografada e as diferenças entre homens e mulheres se apresentam e se reproduzem em todos os tipos de atividades

Keempat Insan, Penggunaan kata insan dalam al-qur’an untuk menggambarkan manusia dengan segala totalitasnya. Kelima Konsep al-ins mengisyaratkan ari “tidak liar” atau “tidak biadab”. Dalam konteks ini menusia merupakan kebalikan dari jin yang menurut dalil aslinya bersifat metafisik KeenamAn- Nas dalam Al- Qur’an umumnya dihubungkan dengan fungsi manusia sebagai makhluk sosial.

Published: September 2020

Maninjau lake uses ships designed in a simple way without significant innovation from time to time. This case is caused by design methods that are based on hereditary knowledge from  generations to generations, so that the ships that are made tend to have the same shape and size. Innovation is needed to get a higher level of efficiency and effectiveness on a ship. The innovation that needs to be done is the design of ships with a multi-hull shape or catamaran. The pre-design of the catamaran hull is based on using the comparation method as the dimension ratio of the ship, so that the dimensions of the ship are LWL = 4 m; LPP = 3.96 m; B = 1.7 m; B1 = 0.36 m; D = 0.7 m; d = 0.307 m. After that, testing the resistance (resistance) while determining the amount of Power needed. The next step is to analyze Stability and Seakeeping to determine the efficiency and effectiveness of the hull type. Analysis carried out on this type of hull was applied to several models, then the best hull design was found. Each design is distinguished by hull shape, but has the same displacement which is equal to 0.448 tons. The first model of the catamaran hull with the type of Flat Inside Symmetry; second with the type of symmetry Flat Outside; and the third type with gastric Asymmetry.

The distance between the Dharmasraya district and the provincial capital has an impact on the contrast of the quality of education carried out which causes the community to not understand the importance of education. So that some of the human resources in Dharmasraya have become manual labourers in plantations and factories. The purpose of implementing this service activity is to provide a solution to the problems faced by the community, especially for school dropouts. Most of the dropout youths who are junior high school (SMP) level do not have special competencies that make them have added value. The work carried out by this young man is only limited to gardening and does not guarantee economic prosperity. Through this service activity, TIM strives to provide competency in the welding field that can be used to open a business that is much needed by the community. The training activities were designed for 3 days which will be held from October 12 to October 14 2018. The speakers in this activity were Drs. Purwantono, M.Pd, who has a BNSP level I welding certificate and the second speaker is Junil Adri, M.Pd.T who has a BNSP level III welding certificate. On the first day, the speaker will convey the basic concepts in the welding process and demonstrate how to make weld grooves and connect the plate in the welding process. On the second day, the speakers began to invite participants to design products that could be made through welding activities in accordance with the needs of the community. In this activity, TIM directed to make a trellis fence. TEAM began to guide participants in the process of making a trellis. On the third day, the TEAM provided direction on how to weld entrepreneurial opportunities in the field. The chairperson of the service with TIM asked the kenagarian to be able to accommodate the birth of new entrepreneurs for youth who could make independent and productive people.

Published: September 2020

Stone chisels produced by blacksmiths which are made using leaf spring steel are often too brittle or fragile so that when they are used, they often occur in the form of cracks and breaks. This study aims to determine the appropriate hardness level for stone chisels. The process is carried out by comparing the hardness level of stone chisels that have been used but still in good condition and those that have been damaged. Broken stone chisels have a high adequate hardness compared to good stone chisels so that damaged stone chisels can be reconditioned to get the right rock chisel hardness. Heat treatment is given to damaged stone chisels to improve the hardness level by normalizing the process to restore the initial mechanical properties of the steel and increasing the hardness of the chisel by heating the steel and then quenching it using water cooling media. Based on the experimental process carried out that the hardness level of a good stone chisel is between 228 HB to 320 HB by heating the duan spring steel to a temperature of 780ºC with a hold time of 10 minutes then cooling it quickly using water and stone chisels can break when it is used because it has a very high hardness.

The strength of the welding result is strongly influenced by several factors, one of which is the selection of high current. This study aims to determine the effect of high current of welding on the strength of low carbon steel welding joints. The process of welding the material uses the open V seam connection type. The variations of the high current used were 80 A, 100 A and 130 A. The specimen used was a carbon steel plate with code of 1.0038 with thickness of 8 mm and the electrode used was the E7018 electrode with diameter of 3.2 mm. The strength of the welding results is influenced by arc voltage, amount of current, welding speed, amount of penetration and electric polarity. Determination of the amount of current in metal joints using arc welding affects the work efficiency and welding materials. Based on the research, it was found that welding using high current of 100 ampere produced the highest tensile strength value of all test specimens that were given welding treatment and good penetration results.

Published: September 2020

This study aims to observe the amount of deviation that occurs due to the influence of spring back on the forming process. spring back in question is the back force when the plate undergoes a forming process, but when the load is released, the plate condition will reverse or return to its initial condition. This reversal is due to the factor of the elasticity of the material that is owned. Other factors that influence the bending process include thickness, width, angle of bending and others. object of this research is a sheet metal plate with a thickness of 1 mm - 4 mm. Forming process is done by bending process. This bending process is widely used in the plate forming process, namely to bend the sides of the plate to make it stiffer. This bending process is carried out in cold conditions where the process is carried out at room temperature. This research was conducted by preparing slices of the same width and length and then the process of bending them to form an angle of 20 ° to 120 °. results of this test indicate that the thicker the bent material has the tendency to produce small deviations. This means that the value of the spring back ratio also decreases. The value of the spring back ratio in this study ranges from 1% to 9%. This means that if the bending process is carried out on a steel plate with the resulting bending angle of 90 °, the bending angle of the shoe must be more than 90 °, the excess is 1 ° - 9 °. So that when the load is released, the position of the susdut bends closer to 90 °.
Magnetic Saturation Impact on Three-Phase Shunt Active Power Filters

Published: September 2020

The problem of controlling three-phase shunt active power filters (SAPF) is addressed in presence of nonlinear loads. Previous works generally design control for SAPF based on standard models that assume the involved magnetic coil to be linear. In reality, the magnetic characteristics of these components are nonlinear (especially in the presence of large magnetic flux density in the ferromagnetic core). In this paper, a new oriented control model for SAPF-load system, taking into account for the nonlinearity of coil characteristics, is developed. The control objective is twofold: (i) compensating for the current harmonics and the reactive power absorbed by the nonlinear load; (ii) regulating the inverter DC capacitor voltage. To this end, based on the new model, a nonlinear controller is developed, using the backstepping technical design. It is therefore able to ensure good performances over a wide range of variation of the load current. The performances of the proposed adaptive controller are formally analyzed using tools from the Lyapunov stability and the averaging theory. The performances of the proposed controller is illustrated through simulation

Published: September 2020

Microgrids (MG) are becoming a definitive solution for the integration of renewable energies sources in the energy matrix. As it becomes an independent cluster of energy apart from the main grid, it needs a specialized control called Microgrid Central Controller (MGCC) and consequently a robust communication layer with the primary controllers in order to prevent failure and disturbances to the grid. In Brazil, an effort has been made to build a laboratory structure to simulate a microgrid environment, but with a field approach. This paper proposes a solution to the communication layer, physical and logical, that meet the requirements of a real field application allowing interconnection of real physical equipment to the testbed. The results indicate that the communication should use a physical interconnection with an Ethernet Based Protocol, considering time synchronization and redundancy.

Authors: S. Vergura
Published: September 2020

The field of the Electric Vehicles (EVs) is becoming a strategic laboratory for new solutions focused on the energy saving and/or the renewable energy sources. Regenerative brakes are well known and already applied in recent cars. In this paper, instead, the attention is focused on a regenerative Shock Absorber (SA), which converts its vibration - induced by the road roughness - in electrical energy. The vibration is transmitted to an electric generator through a mechanical component. Finally, the produced energy can be stored in a super capacitor for a future use. The paper proposes a Simulink-based model of this regenerative SA and compares the energy performance when the vehicle travels roads with different roughness, scientifically defined by means an index, said IRI.

Published: September 2020

The purpose of this study was to study the performance of silica gel-air adsorption chiller on two types of adsorber fins by conducting experiments at several cycle times, namely 500, 600, 700 and 800 seconds with specific mass recovery times, heat recovery times, and also variations on the input of the cooling fluid, so that optimal cycle times can be obtained related to COP and SCP. The adsorber fin-spacing which has more tightly fin distance does not determine the better performance of the adsorber for chiller application because the shorter distance of the fin, the cross-sectional area of the silica gel surface that has initial contact with the adsorbate will decrease so that the performance of the adsorber will decrease. The highest cooling capacity and COP obtained are 3.1 kW and 0.52, respectively. The results are obtained on adsorber with 3 mm fin distance and 700 s cycle with hot water inlet temperature of 79°C, cooling water inlet temperature of 29.4°C and chilled water outlet temperatures of 8.5°C
