O Dispositivo Fotográfico, o Contemporâneo e a Fratura do Tempo: um ensaio a partir da produção fotográfica Inframargem – margens de um mundo infravermelho, de Gustavo Bettini
Authors: Barreto Francisco Sá , Medeiros Izabella
Published: April 2021

Concebendo o contemporâneo, para além de sua dimensão coetânea, como a revelação do tempo em que se vive como objeto possível da reflexão, partimos da ideia de que ele traduz uma agenda política renovada, tendo as descontinuidades como importantes instrumentos de (re)construção de sentidos para o mundo público. Tomando como referência a imagem fotográfica enquanto dispositivo de fratura do tempo e seus desafios contemporâneos, lançamos nosso olhar para a produção Inframargem: margens de um mundo infravermelho, do fotógrafo Gustavo Bettini. Nosso objetivo é entender o dispositivo fotográfico enquanto instrumento possível de suspensão e sofisticação das lógicas de racionalização do tempo. A margem, o estranho, a fratura, o não familiar, o desconhecido são pontos de partida para a o desafio da experiência do contemporâneo. O dispositivo fotográfico, nesse cenário, ocupa um lugar de destaque possível à medida que desestabiliza, desprotege a realidade de seus lugares vazios de sentido comum.

Bartleby, o Fotógrafo: notas sobre a negatividade nas imagens fotográficas
Authors: Carvalho Paulo
Published: April 2021

Estas são algumas notas em que levanto hipóteses sobre as condições de possibilidades da enunciação da inapetência. Busco através de certa sintomatologia da negatividade analisar não apenas o discurso de personagens literários como Bartleby, de Herman Melville, mas aquilo que está agenciado a este dizer, sem contudo ser-lhe correspondente ou representante. Procuro um plano dos visíveis, uma arquitetura assignificante, como pode vir a ser a maneira indicial de abordar a imagem fotográfica. Trata-se de uma busca sobre a produção e a rejeição de subjetividades inapetentes; de como a negatividade pode tanto vir a restabelecer o giro vazio dos dispositivos em torno de suas formas de expressão e conteúdo, como pode produzir pequenas rupturas nessas relações, acenar para linhas de fuga.
REVIEW ON THE FATIGUE BEHAVIOR OF THE WHEELS OF RAILWAY VEHICLES IN CONTACT WITH RAIL
Authors: TOTH Constantin Silviu , MĂCUȚĂ Silviu Dănuți
Published: April 2021

Rail transport is essential to the EU's strategy for a more sustainable transport sector, economic and social cohesion and connecting Europeans at and between each Member State. EU trend is to support the railway sector as a clean, main mode of transport at European level. The European rail system carries around 1.6 billion tones of freight and 9 billion passengers each year. The railway sector has a substantial contribution to the EU economy, directly employing over 1 million people. With the technological evolution of railway vehicles, it is important to focus on safety issues. Wheels are one of the most critical components of railway vehicles, as their failure can lead to derailment. Therefore, an exact project on the control of the problem of wheel fatigue and knowledge of the effective parameters on their life, can improve the life of the whole structure. Due to the fact that the nature of the loads applied to the wheels is repeated, fatigue is  very common mechanism of damage that can occur in several ways, such as: nucleation and growth of fatigue cracks, spalling, shelling, and so forth. The main sources of these phenomena are the rolling contact loads, the thermal loads between the wheel-rail and the wheel-brake block, created in the braking phase, the presence of structural defects in the wheel material; it follows that they cannot be omitted in a rigorous design. Increasing of speed aggravates these factors and exacerbates the problem of thermal fatigue of the wheels. In this paper we present a series of studies that focused on the wear of the wheels of railway vehicles in contact with the steering track (rail) to fatigue.
ASPECTS REFERRING TO FATIGUE TESTING OF EPOXY POLYMERIC MATERIALS
Authors: HUMELNICU Costel , AMORTILA Valentin , NOVETSCHI Monica , GINGARASU Mihai
Published: April 2021

Concomitant with the development of new technologies in usage of renewable energies and with the necessity of replacing metal, epoxy polymeric materials are becoming more frequently used. Their main advantages are the reduced weight, high mechanical and corrosion resistance, the possibility to recover, recondition and reutilise the components. Thus, they become suitable for various industries, such as: automobile manufacturing, wind turbine blades, naval industry etc. Increased fragility and low resistance in initiating and developing cracks lead to varied fatigue performance. One way of reducing these disadvantages is to test fatigue in order to observe and analyse its manifestation, before projecting components. This paper presents tests carried on cylindrical epoxy polymeric samples. The samples were manufactured through casting in tubular moulds because of great advantages of this method. The manufacturing time is short, the material usage is maximised and after casting, the samples are smooth and don’t have sharp edges. Hence, the risk of unwanted concentrated stress is eliminated. The testing means assessing the samples to variable loading in rotating bending. For a better precision of test results, it is very important that his method could be accurately repeated with samples, preparing them in similar conditions. The results are used to draw Wohler`s curve using stress-number of cycles (S-N) as coordinates, specific to the tested material. Finally, the level of maximum stress of a material that resists fatigue, without having any ulterior damage can be determined.

2007 ve 2018 Deprem Yönetmelikleri Kullanılarak Farklı Zeminlere Göre ve Farklı Kentler İçin Elde Edilen Tasarım İvmelerinin Karşılaştırılması, Kapadokya Örneği
Authors: KARACA Hakan
Published: April 2021

2019 itibarı ile yürürlüğe girmiş olan Türkiye Bina Deprem Yönetmeliği (TBDY-2018) ile zemin parametrelerinde çok önemli yenilikler getirilmiş ve zemin-yapı etkileşiminin daha gerçeğe yakın modellenebilmesini mümkün hale gelmiştir. Zeminin özellikle büyütme ve küçültme etkisinin yeni şartnamede yer alması, yönetmeliğin bilimsel verilere daha uygun hale gelmesini sağlamıştır. Bu kapsamda, TBDY-2018’den resmi olarak yürürlüğe girmeden önce yürürlükte olan Deprem Bölgelerinde Yapılacak Binalar Hakkında Yönetmelik (DBYBHY-2007) kapsamında yapıların tasarımında kullanılan tasarım ivmeleri ile yeni deprem şartnamesine göre uygulanacak tasarım ivmelerini karşılaştırılması yapılmış ve Kapadokya bölgesi illerinin il merkezlerinde zemin koşullarına bağlı olarak tasarım ivmelerinin ne kadar artıp azaldığını belirlenmiştir. Çalışmanın sonunda, herhangi bir salınım periyodu için, 2018 deprem yönetmeliğine göre tasarlanacak yapıların tasarımında kullanılacak tasarım ivmelerinin 2007 yönetmeliğine göre nasıl değiştiği ile ilgili bir örüntüye rastlanmamıştır. Sadece salınım periyotları büyüdükçe, yeni deprem şartnamesine göre kullanılacak olan tasarım ivmelerinin, eski yönetmelik değerlerine oranının azaldığı görülmüştür. Böylelikle, salınım periyotları daha yüksek olan yapıların tasarımında kullanılacak tasarım ivmelerinin eski yönetmelik değerlerine oranı, düşük salınım periyotlara sahip yapıların tasarım ivmeleri oranlarına göre daha düşük olacaktır.

Published: April 2021

The processing of refractory minerals of gold and / or silver occluded in quartz in sizes less than 1 μm is not viable, due to the chemical inertness of the silica. The treatment of these minerals is usually carried out by reduction of particle size by fine grinding that allows the release of the occluded particles. As an alternative to processing these minerals, has proposed the partial dissolution of the silica with diols in basic medium; in these studies partial dissolution of the matrix has been observed in 25% with triisopropanolamine and 3% mol KOH. The present work shows the effect of the type of base (organic-amines) in the dissolution of the matrix, observing a greater dissolution with the basic character of these and with the chelating effect of the same ones. Et3N was the weak base that showed the highest dissolution of the matrix, observing a dissolution rate (0.67 mmolmin-1) 2.5 times lower than that observed with KOH (1.66 mmolmin-1), similarly the observed effective diffusion coefficient was of an order of magnitude lower than that observed with KOH.

This work presents the study of a circuit used as a Soft Starter for a single-phase AC motor connected to a photovoltaic system. The direct start of a motor connected to an inverter activates its protection because it is not able to withstand the current that the motor demands in its start, that is why a technique is proposed that minimizes and eliminates the high peaks of current that generate Currently there are soft starters or frequency variations and other soft start techniques that are used for three-phase motors, what is required for this case is a soft starter for single phase motors. The circuit used as a test for Soft Starter allows performing the phase control by varying the firing angle. The photovoltaic system with which the soft starter tests were carried out has an inverter of 1,500 W to which a single-phase motor of a quarter of Hp was connected. Measurements were made with a digital multimeter, a hook Wattmeter, a digital oscilloscope and a washing machine motor. The main bases for the development of Soft Starters are left connected to a photovoltaic inverter for the start of single-phase motors.

Over time, wireless sensor networks (WSN) have been used for a variety of applications. Extensive work has been dedicated to various WSN applications. It is important to note that, due to their physical limitations, the sensors are prone to several types of faults. These restrictions can pose serious problems in event detection applications. Especially if the WSNs are deployed in hostile environments, such as the industrial or environmental sector. The detection of anomalies has recently attracted the attention of the scientific community, due to its relevance in real-world applications. The proposed solutions depend to a large extent on supervision and communication, using techniques based on tools such as Machine Learning and Neural Networks. In this context, we introduce the most commonly used anomaly detection techniques in WSN. Compiling and comparing the main methods applied in specific scenarios, we analyze the advantages and conveniences of using any of them.

Published: April 2021

In recent years, the implementation of solar energy facilities has grown, as it is considered an environmentally friendly way to produce electricity. Solar energy can be exploited under different configurations or connection schemes. The most useful connection schemes are the string connection, the power optimizers and the microinverters. Microinverters have a wide advantage compared to the other schemes due to their ability to take advantage of solar energy under different environmental conditions, such as partial shading, temperature and irradiation. The implementation of microinverters has been slowed down because of its high cost and reduced lifetime. In general, the design of microinverters commonly includes elements such as transistors, electrolytic capacitors, sensors and a microcontroller. Electrolytic capacitors are commonly used as decoupling stages, even though they present a lower lifetime due to high frequencies of operation and current rises. In this paper, a new microinverter topology is presented, it uses a low-cost array of multilayer capacitors to filter high frequencies and get a low-cost topology.

Published: April 2021

This article discusses the relationship between precocious puberty and the peer relationships of preadolescent girls in public primary schools in Kiambu County, Kenya. This article is based on a case study of twelve selected public primary schools (representing the 12 constituencies) of Kiambu County, Kenya. The sample population was a total of four hundred and ten pre-teenage girls drawn from eight to twelve-year-old girls, and eight class teachers, who were purposively sampled from twelve randomly selected public primary schools in the study location. This was a mixed study that utilized both quantitative and qualitative data collection methods. The self-rating scale for pubertal maturation and the peer connectedness scale was used to assess for signs of precocious puberty and the quality of peer relationships respectively. In addition, structured interviews and focus group discussions were used to gather additional primary data. The instruments were pilot-tested on a sample of thirty-six respondents who were purposively sampled from three public primary schools in the sample location, and who were omitted from the actual study sample. The quantitative data was analysed using the Statistical Package for Social Sciences (SPSS) version 26, while the qualitative data was analysed using the content analysis approach. Analysed data was presented using both figures and tables. This study found a significant relationship (β=0.258, p=0.011) between precocious puberty and peer relationships among preadolescent girls. This was confirmed by the interview responses and the focus group narratives. The study concluded that earlier pubertal maturation led to strained peer relationships among preadolescent girls. This article recommends that forums to educate children on the stages of development and how to handle each of them be incorporated in the curriculum, to prepare girls for pubertal maturation whenever it occurs.

Authors: Lin Yuan-Horng , Tsai Liang-Ting
Published: April 2021

The purpose of this study is to evaluate the psychometric properties of mathematics reading assessment based on structural equation model (SEM) and item response theory (IRT). The mathematics reading assessment is conducted in the form of text-reading related to real-life probability and statistics issues. The sample is 789 sixth graders from 13 primary schools in Taiwan. The latent construct of mathematics reading includes three factors which are based on the content area reading components provided by M. C. McKenna and R. D. Robinson. These three factors of mathematics reading assessment in this study are general reading comprehension, prior knowledge of mathematics, and mathematics-specific skills respectively. Firstly, the researcher develops the mathematics reading assessment and confirms the item difficulties, item discriminations, and reliability of assessment. A structural equation model (SEM) is adopted to test the factor construct of the mathematics reading assessment. According to the analysis, it shows that the item difficulties, item discriminations, and reliability are very well. The structural equation model reveals there exist three factors that conform to the assumption of content area reading components mentioned above. Secondly, this study calibrates item characteristics by the three-parameter logistic model of item response theory (IRT). Results indicate that all item fitness performs well. Items belonging to prior knowledge of mathematics have the highest item discriminations. Items of mathematics-specific skills have the highest item difficulties. This study establishes a well-structured mathematics reading assessment. Results could also provide references for instruction and assessment of mathematics reading. Finally, based on the findings of this study, some recommendations and suggestions for future researches and methodologies are also discussed.

Published: April 2021

The integration of mobile augmented reality technology (MART) into the education system since the last two decades have brought to the topic of discussion among many scholars. Although numerous studies have highlighted its huge potentials and benefits toward both teacher's and students' teaching and learning process, several researchers reported that teachers’ readiness to integrate mobile augmented reality technology is still uncertain. Given the importance and consideration of research that has been undertaken, the present study was set to examine the Malaysian pre-service teachers’ readiness toward integrating MART into their learning and future teaching process. The Technology Acceptance Model (TAM) was adapted as the theoretical grounding of the study in explaining and predicting pre-service teachers’ decision to integrate mobile augmented reality technology. Data of the study was gathered from 303 Malaysian pre-service teachers and were analysed using the descriptive analysis of SPSS and Partial Least Square (PLS) of Structural Equation Modelling (SEM). Findings from the study demonstrate that pre-service teachers’ readiness to integrate MART is at a moderate level. The study also suggested that pre-service teachers’ perceived usefulness has the most significant direct effect on their decision to integrate MART. On the basis of these findings a purpose model is developed, and implications of theory development, practices, and policymaking are discussed in this paper.

There is lacking technology application in black pepper farming to automate daily routine activities in monitoring black pepper vines growth and nutrient need. With the revolution of Industry 4.0 (IR4.0), and tremendous improvement in the internet of things (IoT), the application of precision agriculture to pepper farming is a thing to consider for its benefit. This paper to explore the use of IoT to monitor fertilizer requirement for pepper vines using pH sensor. The pH sensor attached to Raspberry Pi 3 will be collecting the data and forwarding it to the cloud database for farmer reference and take decision based on data presented in form of a digital report from the database. The Python environment provides the space for coding in Raspberry Pi. SQL and PHP software is used to design the user interface and data management in the relational database management system. The information about pH provides a better understanding of how pH parameter affects the growth of pepper vines. The farmer will be able to access the information anywhere and anytime. Therefore, our proposed system will greatly help the pepper farmers in Sarawak in managing the usage of fertilizer as a way to minimize farm inputs, thus increase their profit.

This research aims to create a model for acculturation dialogue between representatives of religion, local wisdom, and power. The study uses a socially defined paradigm as an approach to cultural acculturation and adopts the theory of institutional development acculturation of Islam (almuhaafadhatu ala al-qadiimi al-shaalih wa al-akhdu bi al-jadiidi al-ashlah). This research found five models for acculturation dialogue between religion, local wisdom and power, namely, 1) taggayyur /deculturating /changing, 2) takammul /additive/ perfecting, 3) tahammul /considerate /tolerant, 4) tasallum /inclusive /receptive, and 5) tamsarrub /institutive /absorbing. The first acculturation model tends to reject the other cultures. The second model tends to be open and cross-sectoral in its approach. The third model is tolerant and accepting of all. The fourth model tends to be open and objective in recognizing truth and goodness from outside of itself, an acculturation model that has the potential to create peace and harmony. The fifth model seeks to absorb universal values so that together cultures are institutionalized into a new cultural unity.

This article develops a method of modeling meta-analytical structural equations (MASEM) which merge meta-analysis and modeling of structural equations on infrastructural issues in underdeveloped areas of Java Island in Indonesia. The implementation of this research is MASEM modeling using the approach of generalized least squares. The modeling is used to analyze the factors affecting the infrastructure of the underdeveloped areas in the provinces located on Java Island. This study uses three exogenous latent variables (economy, accessibility, and regional characteristics) and one endogenous latent variable (infrastructure). The results of the implementation of this study indicate that the "accessibility factor", which is an indicator of the average distance from the capital/district to access to health services, has a positive and significant effect on the infrastructure of underdeveloped areas of Java Island. This result can be used as a reference for the government in determining policy directions to tackle the problems of underdeveloped areas; in particular, in the infrastructure dimension.

This article describes online learning in early childhood education in Indonesia. Particular attention is paid to the Greater Jakarta area, which is a buffer area of the capital city of Indonesia. This study used a survey method with a questionnaire containing five open-ended questions that the respondents could fill in freely. The questionnaire was distributed through an online form to early childhood education teachers and parents of young children. Respondents' answers were grouped based on their similarity and sorted based on the number of answers, then analyzed quantitatively and descriptively. The results showed that online learning is difficult to implement in early childhood education. The enforced application of online learning in early childhood actually creates many obstacles and causes an unfavorable impact on early childhood behavior while learning. However, online learning in early childhood must still be implemented during a pandemic as it is the only option. The solution to increase the abilities and skills of teachers in planning and implementing online learning include the ability to involve parents. The results of this study are expected to be a reference by teachers, parents, and early childhood education providers in implementing effective online learning in early childhood education in a fun way and paying attention to the characteristics of early childhood.
