Published: November 2023

As embalagens e garrafas são responsáveis pela geração de uma grande quantidade de resíduos na cadeia produtiva do Polietileno Tereftalato (PET). A Indústria da Construção Civil, preocupada com a sustentabilidade urbana, tem indicado a viabilidade de reciclagem desse polímero como insumo para a produção de artefatos de concreto. O objetivo deste trabalho é investigar o desempenho térmico de telhas de concreto fabricadas por extrusão, com substituição parcial de agregado miúdo (areia natural) por resíduos de PET, comparando-as com telhas de referência (sem a substituição). Foram realizadas as seguintes etapas metodológicas para amostras de telhas de referência (sem PET) e com PET: definição do traço para fabricação de telhas, avaliação das propriedades físicas de absortância, emissividade e condutividade térmica, e medição do comportamento térmico das telhas em condição in situ. O PET apresentou pouca interferência nas propriedades físicas de absortância e emissividade das telhas, mantendo-as dentro dos limites normativos. As telhas com PET, devido ao maior calor específico, resultaram em um maior isolamento e armazenamento de energia, ou seja, uma maior retenção do calor dentro dos ambientes, gerando maior consumo energético para refrigeração durante o período noturno. Portanto, a sua instalação deve ocorrer preferencialmente em edificações com uso diurno.

Published: November 2023

O estudo do conforto térmico em áreas externas é importante para a compreensão dos níveis de conforto dos indivíduos e para o planejamento urbano sensível ao clima. A percepção térmica dos usuários dos espaços abertos é influenciada por diversos fatores, sendo a utilização da climatização artificial nos ambientes fechados um desses aspectos. Este estudo busca verificar a percepção térmica dos usuários dos espaços abertos da cidade de Pelotas - RS, sob o aspecto do impacto gerado pelo uso prolongado do ar-condicionado nos ambientes fechados. Foram realizadas 53 campanhas de monitoramento de dados simultaneamente à aplicação de questionários à população entre julho de 2019 a março de 2020. Para o registro das variáveis foi utilizado o medidor de estresse térmico TGD-400 e os questionários foram estruturados conforme as normas ISO 8996 (2004), 7730 (2005), 9920 (2007) e 10551 (2015). O índice Temperatura Fisiológica Equivalente (PET) foi utilizado para comparar os resultados obtidos para aqueles que utilizam a climatização artificial e os que usam a ventilação natural. Os resultados apontam que o impacto causado pela utilização da climatização artificial altera a percepção térmica dos indivíduos, influenciando, portanto, nos limites das faixas de conforto térmico.

Published: November 2023

O objetivo do estudo foi investigar o impacto econômico no consumo de energia elétrica em função da variação da orientação de uma edificação escolar na cidade de Maceió/AL e do coeficiente de performance (COP) de aparelhos condicionadores de ar. Em algumas regiões quentes e úmidas, particularmente em Maceió/AL, muitas edificações são construídas de modo único, quer sejam ventiladas naturalmente ou climatizadas de forma artificial. Diante desse cenário, os parâmetros acima mencionados foram simulados no EnergyPlus para temperaturas no intervalo entre 21°C e 28°C, definidas segundo critérios adotados pela Instituição de ensino analisada. Os resultados apontaram para a economia no consumo de energia de até 14% para fachadas orientadas a norte e sul e de até 34% para a variação do COP. Tais resultados reforçam o impacto gerado pela adequada implantação do edifício no lote bem como na especificação técnica de aparelhos condicionadores de ar, de forma a promoverem o conforto térmico através do uso racional de energia elétrica.

Published: November 2023

Este artigo visa estudar a influência da obstrução causada pela espacialização dos blocos de edifícios do condomínio Morada das Artes localizado em Maceió – AL, na incidência de luz natural nas edificações e no ofuscamento em um de seus ambientes internos. A qualidade da iluminação natural em ambientes internos depende, entre outras coisas, da forma urbana e da relação da edificação com o entorno, parâmetros definidos pela legislação municipal da cidade, como, por exemplo, o afastamento entre as edificações, o impacto deste afastamento deve ser investigado de modo a proporcionar bases para elaboração de legislações e normas para edificações e ambientes urbanos. Este estudo se baseou em simulações computacionais utilizando o software Troplux e avaliou a iluminação incidente na fachada e o ofuscamento em espaços internos. Como resultados, constatou-se que para a distância adotada neste projeto (6,10m) embora a obstrução promova uma diminuição da iluminância incidente na edificação, ela não compromete a iluminação natural interna no centro do ambiente, chegando em alguns momentos a promover ofuscamento e indicando a necessidade de utilização de algum dispositivo de controle. Este trabalho pretende contribuir para a produção habitacional multifamiliar brasileira que se encontra em um período de constante ascensão com os programas de financiamento habitacional do Governo Federal.
Desempenho térmico associado ao envelhecimento de fachadas em edificações multifamiliares nas zonas bioclimáticas 5 a 8
Authors: Cavalcanti Fernando Sá , Monteiro Leonardo Marques
Published: November 2023

Este artigo apresenta uma análise do desempenho térmico de uma edificação padrão (multifamiliar vertical) na tipologia “H” considerando o envelhecimento dos sistemas de fachadas ao longo dos anos para quatro zonas bioclimáticas brasileiras seguindo os requisitos da norma de desempenho para edificações (PHFTUH e Tomáx). Além do desgaste natural pelas intempéries proposto pela normativa brasileira, foi investigado o desempenho destas edificações em cenários climáticos futuros, para 2050 e 2080 o que representa uma avaliação considerando o período de vida útil destes sistemas. Esta avaliação se deu por meio de simulações computacionais para três padrões de absortância e seu comportamento ao longo deste período utilizando o software energyplus. Os resultados apontam que para cores claras o desempenho térmico desta edificação se comportou de modo satisfatório ao longo dos anos, no entanto, embora a TOmáx tenha obtido valores dentro do estabelecido em norma, o PHFTUH não se comportou da mesma forma, o que pode comprometer o uso e ocupação destes espaços, principalmente para fachadas com cores médias e escuras.

Authors: Santos Ronaldo Soares dos , Morais Juliana Magna da S. Costa
Published: November 2023

Em João Pessoa/PB, a poluição sonora é a que apresenta maior número de denúncias e queixas por parte da população, segundo dados da Secretaria do Meio Ambiente – SEMAM. Isso se dá, em parte, devido à acelerada urbanização registrada nas últimas décadas aliada ao crescimento da frota veicular/malha viária na capital paraibana – principal agravante desse tipo de poluição ambiental. Diante disto, o mapeamento do ruído urbano é uma importante ferramenta para viabilizar um planejamento territorial articulado com a gestão ambiental, identificando pontos críticos, diagnosticando a qualidade sonora dos espaços e auxiliando na construção de políticas públicas para mitigação do ruído. Dessa forma, o presente trabalho objetiva mapear o ruído de tráfego do bairro Jardim Oceania, um dos setores imobiliários mais valorizados na cidade de João Pessoa/PB, visando realizar dignóstico quali-quantitativo do seu cenário acústico. Para tal utilizou-se metodologicamente da elaboração de mapa de ruído do bairro através do software SoundPLAN. Oservou-se, com a concepção dos mapas de ruído de tráfego, a predominância de níveis de pressão sonora entre 60 dB(A) e 70 dB(A), na maioria das quadras do bairro – valores já considerados nocivos à saúde humana pela OMS– bem como superiores ao que se preconiza para estas áreas segundo a NBR 10151.Assim, de modo espacializado consegue-se demonstrar a poluição sonora no bairro, o qual por ser muito valorizado do ponto de vista imobiliário e ainda possuir algumas áreas livres para expansão, precisa ter atenção da gestão pública para este quesito.

Operation and maintenance of step up transformers require constant monitoring of electrical and temperature parameters during operations, as well as periodic control of oil quality and electrical tests of the insulation system and measurement of winding and magnetic circuit parameters. The transformer that is the subject of this paper was in operation for about 35 years. Through periodic analyzes of the insulating oil and complex diagnostics of the condition, it was concluded that there is increased heating in the transformer that affects the cellulose insulation, but it is estimated that it does not cover a large area (hot spots possibly on the insulated winding joints or in the magnetic core). On-line monitoring system with continuous monitoring of the content of dissolved gases and water is installed. During the overhaul in 2022, it was observed that the insulating elements and parts of the magnetic shunts – fluxflow guides, between the winding and the upper yoke of the magnetic circuit, were partially disintegrated and scattered in parts. It was decided to dismantle the transformer and replace it with a spare one. The paper will present the history of transformer operation, the results of analyzes and diagnostics of the condition during exploitation, as well as a detailed description of transformer repairs in the field.

Trends in the modern development of electricity transmission lead to greater use of cable networks and GIS facilities. There is a need to test, monitor and diagnose partial discharges at GIS facilities. Various standard and non-standard approaches are used for PD measurements, which, according to the type of sensor used, are called UHF measurements, HFCT measurements, TEV, ultrasonic (acoustic) and other measurements. In accordance with the given sensors, adequate acquisitions are used. Signal analysis can detect the intensity, type and position of the source of partial discharges. The system can be used in production for test or handover tests that can indicate deficiencies within the GIS, the presence of a foreign body and its position in the chamber, and other deviations. Tests and state diagnostics during exploitation can indicate changes and improve GIS maintenance. Research in this paper should show the possibilities of realization of tests, monitoring and diagnostics in GIS 110kV plants in Serbia and their integration into the monitoring system.

The imperfection of the insulating dielectric in the form of microcavities and various shapes of cracks of and material of different chemical composition leads to the appearance of an inhomogeneous electric field. This results in an increase in electrical stress, and therefore a greater probability of insulation breakdown. In this paper is been analyzed the influence of imperfection in the structure of the solid dielectric of the high voltage cable, in the form of hollows, impurities, as well as the appearance of electric and water treeing, on the distribution of the electric field and electric scalar potential inside the cable. Calculations were performed using the COMSOL Multiphysics software package, which is based on the finite element method. The analysis was performed on the model of single-core cable 64/110 kV, type A2XS(FL)2Y. The results showed that inside gas-filled cracks there is a significant increase in the intensity of the electric field strength vector, while the probability of partial discharges, which eventually lead to electrical treeing, also increases. In the case of cracks filled with water, a drastic increase in the intensity of the electric field strength vector was observed on the outer surface of the crack, which proved that the development of water treeing begins at the place of increased intensity of the electric field strength vector, spreading in the direction of its action. In the end, it was shown that with the appearance of water treeing, the risk of insulation breakdown is greater, and the importance of monitoring the development of water treeing was determined.

Published: November 2023

Kitle iletişim araçlarının dünya çapında yaygınlaştığı, toplumların yazılı kültürden görsel kültüre geçiş yaptığı günümüzde, Fransız teorisyen Guy Debord'un seneler önce tanımını yapmış olduğu “gösteri toplumu” varlığını halen sürdürmektedir. İçeriklerin tamamının gösteri formatına dönüştüğü enfo-eğlence çağında, medyanın en etkili aracı olan televizyonun öncelikli işlevi, insanlara eğlence, haz ve keyif sunmak haline gelmiştir. Televizyon programlarında bu kaygılarla ortaya konulan büyüleyici gösteriler, bilginin içeriğinin yeniden tanımlanmasına ve gösteri toplumunun değerlerinin yaşama derinlemesine nüfuz etmesine aracılık etmektedir. Kapitalist sisteme hizmet eder şekilde ödüle giden yolda bir araç olarak yeniden tanımlanan “bilgi”nin, kitlelerin ilgisini çekebilmek amacıyla eğlence unsuru ile harmanlanarak “bilgi yarışması” adı altında bir “medya gösterisi”ne dönüştürülmesi, Debord’un çıkarımları kapsamında irdelenenebilecek bir olgu olarak ele alınabilir. Popülerliğini uzun bir süredir korumakta olan “Kim Milyoner Olmak İster” adlı televizyon programı, gösteri toplumunda bilginin gösterinin yapı taşlarından birine dönüştürüldüğü ve başta eğlence olmak üzere tüketim kültürüne dair unsurların ön plana çıkarıldığı bir bilgi yarışması olarak önemli bir örnek teşkil etmektedir. Bu bağlamda, bu çalışmada, bilginin metalaştırılarak ihtişamlı bir medya gösterisi haline getirilmesinde öncülük etmiş olan “Kim Milyoner Olmak İster” yarışma programının Türkiye’deki uyarlamasının program formatına dair unsurları olan yarışma kuralları, soru içerikleri, seyirci profili, sunucu profili ve yarışmacı profili, gösteri toplumu ve medya gösterisi kavramları bağlamında ele alınarak detaylı bir çözümlemesi yapılmıştır.

Bu çalışmanın amacı, 1950’lerin Türkiye’sinde gayrimüslim azınlıkların yaşadığı sorunları, dönemin sosyo-kültürel ve siyasi yapısına uygun olarak Kulüp dizisi özelinde ötekilik/ötekileştirme bağlamında analiz etmektir. Bu bağlamda dizide geçen diyaloglar, sözcükler üzerinden analiz edilerek gayrimüslim azınlıklara yönelik o dönemde kullanılan kalıplaşmış yargılar deşifre edilmiş, gayrimüslim azınlıklara dönemsel bakışın hangi anlamlar muhteva ettiği objektif bir bakışla irdelenmiştir. Medyada çok fazla değinilmeyen azınlıklık grubun (İstanbul’da yaşamlarını sürdüren Sefarad Yahudilerin) kültürel değerlerinin dizide nasıl yansıtıldığı, unutulmuş bir kültürün tekrardan ayyuka çıkması adına kıymetli olmakla birlikte bu çalışmanın önemini de ortaya çıkarmaktadır. 10 bölüm olarak yayınlanan dizide gayrimüslimleri ötekileştiren 18 söylemin olduğu saptanmıştır. Söylemler, Norman Fairclough tarafından geliştirilen söylem çözümlemesi yöntemi ile analiz edilmiştir. Fairclough’un analiz yönteminin tercih edilme nedeni, film ya da dizi sanatında görüntü kadar karakter diyaloglarının geniş bir şekilde yer tutmasıdır. Yöntem bu haliyle diyalogların dilsel yapısını anlamaya yardımcı olması, dizide kurulan ideolojik düşüncelerin nasıl temellendirildiğini ortaya çıkarması bakımından önemli veriler sunabilmektedir. Yapılan analizler sonucunda Kulüp dizisi özelinde 1950’ler Türkiye’sinde gayrimüslim ve Türk vatandaşların ötekileştirme pratiklerine maruz kaldıkları tespit edilmiştir.

Published: November 2023

Purpose: This study examined the anthropometric and biochemical indices of infants fed complementary foods developed from millets (M), orange-fleshed sweet potatoes (OFSP), carrot (CF), periwinkle meat (PMF) and oyster meat flour (OMF) blends.

Materials and Methods: Six different blends of flour were formulated using the recommended guideline for the formulation of complementary food for infants 6 – 12 months. The blends were as follows 89: 11 M/C; 70:30 M/OFSP; 57:32:11 M/OFSP/C; 65:20:5:10 M/OFSP/C/OMF; 49:29:7:15 M/OFSP/C/PMF and 70:13:3: 7:7 M/OFSP/C/PMF/OMF while Cerelac was used as the control diet. Thirty-five children aged 6-12 months enrolled in this study. Seven groups comprising of 5 children each consumed cerelac (control diet), millet/carrot (Test diet I) millet/OFSP (test diet II), millet/OFSP/carrot (test diet III), millet/OFSP/carrot/oyster (test diet IV), millet/OFSP/carrot/periwinkle (test diet V), and millet/OFSP/carrot/periwinkle/oyster (test diet VI), respectively.

Findings: The children were fed with 50 g/day of the diets over a 6 months period during which anthropometric (weight, length, mid-upper arm circumference, head circumference, and chest circumference) and biochemical assessments (iodine level, hemoglobin level, calcium level, and vitamin A level) were carried out before and after test product ingestion. All children fed on the test diets had an increase in anthropometric parameters. Test diet VI had the highest percentage effect on biochemical and anthropometric parameters at the end of the study. The effect of test diet VI on the hemoglobin levels of the infants was significantly (p<0.01) higher than other test diets.

Implication to Theory, Practice and Policy: Dietary interventions incorporating carrots, OFSP, periwinkle, and oyster exhibited favorable impacts on the nutritional well-being of infants. Consequently, it ought to be regarded as a superior choice when devising nutrition initiatives aimed at enhancing the nutritional condition of children residing in regions where millet-based porridge prevails as the primary complementary food.

Published: November 2023

The Reserve Bank conducted its sixth triennial Consumer Payments Survey (CPS), which provides detailed information on how Australians make their payments. The 2022 CPS provides the first comprehensive snapshot of consumer payment behaviour following the changes brought on by the COVID-19 pandemic. The survey shows that most in-person payments are made by tapping cards or mobile devices, even for small purchases. This means the share of in-person transactions made with cash halved, from 32 per cent to 16 per cent, over the three years to 2022. The demographic groups that traditionally used cash more frequently for payments – such as the elderly, those on lower incomes and those in regional areas – saw the largest declines in cash use. Cash usage has generally been replaced with card payments. While Australians are aware of and use a range of other newer payment methods, such as digital wallets and buy now, pay later services, they still make up a small share of payments.

This research abstract presents an assessment of the perceptions of parents and learners towards online and modular learning in the junior and senior high school education setting in Baguio City. The study aimed to investigate the perceptions of both parents and learners regarding various aspects of online and modular learning. The research employed a quantitative data collection method. A structured survey questionnaire was distributed to parents and learners to gather quantitative data, and this included questions related to the time allocated for learning activities, the distribution and retrieval of modules, the effectiveness of learning assessments and activities, the delivery of learning, efficiency of the educational process, accessibility to learning materials, teaching methods, and the overall comfort of the learning experience. The survey utilized a Likert scale to measure responses, allowing for the calculation of mean ratings. In addition to the quantitative data insights were gathered through open-ended questions in the survey, where participants could provide detailed feedback and comments on their experiences with online and modular learning. The findings revealed that both parents and learners generally held positive perceptions of online and modular learning, with parents showing particularly high satisfaction with the time allocation for learning activities, module distribution, and the effectiveness of assessments. Learners, on the other hand, expressed strong satisfaction with the delivery of learning and the efficiency of the educational process. This research demonstrates the positive reception of online and modular learning among parents and learners in Baguio City, highlighting the potential effectiveness of these educational approaches in junior and senior high school settings.
