Published: December 2020

Penelitian yang telah dilakukan bertujuan untuk membuat keramik berpori berbasis lempung dan meningkatkan persentase pori keramik menggunakan anodizing technique. Proses pembuatan keramik berpori dilakukan secara manual melalui lima tahapan yaitu penghalusan lempung, pencampuran bahan pembentuk keramik, pencetakan dengan bentuk setengah bola berongga, pengeringan dan sintering pada suhu 945OC. Hasil penelitian menunjukkan nilai susut massa dan susut volume tertinggi setelah fabrikasi berturut-turut sebesar 14,41% dan 33,95%. Proses anodizing technique menggunakan larutan elektrolit HCl 0,2 M dengan rapat arus 25 mA/cm2  dan variasi waktu anodizing yaitu 10, 15, 20, 25 dan 30 menit. Porositas tertinggi diperoleh dari sampel dengan waktu anodizing 30 menit sebesar 49,34%. Namun sampel yang diberi perlakuan anodizing selama 30 menit mengalami penurunan nilai laju alir sekitar 59% dibandingkan sampel tanpa perlakuan anodizing. Hal tersebut diduga disebabkan oleh pembentukan lapisan alumina oksida saat proses anodizing. Nilai laju alir tertinggi justru diperoleh sampel dengan variasi waktu anodizing 10 menit. Berdasarkan hasil uji yang diperoleh, porositas dan laju alir dipengaruhi oleh waktu anodizing. Porositas cenderung meningkat dan laju alir keramik berpori cenderung menurun seiring pertambahan waktu anodizing.

Authors: Setiadi Haris , Azwar Azrul
Published: December 2020

Telah dilakukan studi tentang respons optik nanopartikel perak berlapis SiO2 menggunakan metode aproksimasi kuasi-statik. Hasil studi menunjukkan bahwa spektrum efisiensi hamburan cahaya oleh nanopartikel sangat bergantung pada ketebalan lapisan SiO2 dan jari-jari nanopartikel perak. Pertambahan ketebalan SiO2 akan menyebabkan spektrum efisiensi hamburan cahaya mengalami pelebaran (broadening) dan bergeser ke arah panjang gelombang yang lebih besar (redshift) dengan nilai puncak efisiensi hamburan menurun secara eksponensial. Sebaliknya, pertambahan jari-jari nanopartikel perak akan menyebabkan spektrum efisiensi hamburan cahaya mengalami penyempitan dan bergeser ke arah panjang gelombang yang lebih kecil (blueshift) dengan nilai puncak efisiensi hamburan meningkat secara eksponensial. Selanjutnya, diperoleh pula bahwa panjang gelombang puncak spektrum efisiensi hamburan mengalami redshift secara linier akibat peningkatan indeks bias medium di sekitar nanopartikel. Hal ini mengindikasikan bahwa nanopartikel perak berlapis SiO2 berpotensi dalam aplikasi penginderaan indeks bias. Hasil perhitungan kinerja penginderaan indeks bias nanopartikel perak berlapis SiO2 memiliki sensitivitas sebesar 17 nm/RIU dengan nilai figure of merit(FOM) sebesar 6,789  104 RIU-1.

Photochemical Degradation of Short-Chain Chlorinated Paraffins in Aqueous Solution by Hydrated Electrons and Hydroxyl Radicals
Authors: DiMento Brian , Tusei Cristina , Aeppli Christoph
Published: December 2020

Short-chain chlorinated paraffins (SCCPs) are a complex mixture of polychlorinated alkanes (C10-C13, chlorine content 40-70%). While these compounds are categorized as persistent organic pollutants, there are knowledge gaps about their environmental degradation, particularly the effectiveness and mechanism of photochemical degradation in surface waters. Photochemically-produced hydrated electrons (e-(aq)) have been shown to degrade highly chlorinated compounds in environmentally-relevant conditions more effectively than hydroxyl radicals (·OH), which can degrade a wide range of organic pollutants. This study aimed to evaluate the potential for e-(aq) to degrade SCCPs, and compare this reaction to ·OH-mediated degradation. To this end, the degradation of SCCP model compounds was investigated under laboratory conditions that photochemically produced e-(aq) or ·OH. Resulting SCCP degradation rate constants for e-(aq) were on the same order of magnitude as well-known chlorinated pesticides. Experiments in the presence of ·OH yielded similar or higher second-order rate constants. By compiling literature data for a wide range of chlorinated compounds, it was found that higher chlorine content results in higher rate constants for e-(aq) and lower for ·OH. Above a composition of approximately 60 % Cl, the e-(aq) second-order rate constants were higher than rate constants for ·OH reactions. The results of this study imply that SCCPs are susceptible to photochemical degradation in the environment, facilitated by dissolved organic matter and other sources of reactive intermediates in sunlit surface waters.

Malaysian government started the Movement Control Order (MCO) on 18th March 2020, as one of the initiatives to prevent the more massive outbreak of COVID-19. Recent statistics showed a rapid rise in the numbers of positive COVID-19 patients. However, the statistics on COVID-19 patients being discharged showed that the higher authority was very committed in managing COVID-19 crisis. This online study was conducted among 1,543 Malaysian adults using a validated questionnaire to explore more findings on the Malaysian’s Knowledge, Attitude and Practice (KAP) level towards COVID-19 prevention during the MCO period. Descriptive study and binary logistic regression were performed using SPSS version 22. This study showed that the majority of respondents have good KAP level regarding COVID-19 prevention. WhatsApp and Telegram were the primary sources of information used by the respondents. Education level was the main predictor for knowledge (OR: 2.083, CI: 1.605-2.702), attitude (OR:1.854, Ci; 1.42-2.42) and practice (OR: 1.745, CI; 1.326-2.096) regarding COVID-19 prevention (p<0.001). Knowledge (OR; 1.636, CI: 1.302-2.054) and practice (OR;2.328, CI: 1.858-2.916) were predictors of attitude regarding COVID-19 prevention (p<0.001).

Impact of two non-nutritive sucking patterns on the development of anterior open bite in children of two kindergartens in Baghdad city
Authors: Al Duliamy Munad  J
Published: December 2020

Background: Non-nutritive sucking habit (NNSH) is the main environmental causative factor that disturbs normal orofacial development. In spite of the harmful effect of pacifier as a NNSH, mothers aware from the other types of NNSH like thumb sucking far more than pacifier use. Open bite is one of the most challenging malocclusions in orthodontics due to the high prevalence of relapse after treatment, so preventing the causative factor of its occurrence is essential at early age of child life. This study aims to assess the impact of two non-nutritive patterns on the development of anterior open bite in primary dentition and to compare which of these habits mostly affect open bite development. Materials and Methods: The sample consisted of 313 Iraqi children (135 boys, 178 girls), aged 3-5 years, enrolled at two public kindergartens in Baghdad city, the Capital of Iraq. A pre-tested questionnaire with clinical examination were used to obtain data regarding thumb sucking, pacifier and the presence of open bite. Excel sheets were used for data processing, and Chi square test was used in data analysis. Results: There was a significant association between NNSH and the development of open bite (p value = 0.01). No gender differences in open bite prevalence were observed. The prevalence of non-nutritive sucking habits and open bite was 63.11% and 52.9% respectively with no gender difference. There was no significant differences between the effect of pacifier and thumb sucking habits on the development of an anterior open bite. Conclusion: Both pacifier and thumb sucking at preschool age are significant causative factors that lead to development of open bite in primary dentition. Encouraging mothers to ban and discontinue pacifier and thumb sucking habits as early as possible in the child's life is a crucial factor to prevent open bite development. On the other hand if general health of the child indicates the use of pacifier, mothers should use an orthodontic pacifier and for short time.

间断平衡框架下中国民办高等教育政策变迁分析
Authors: 蔡 金堂
Published: December 2020

中国民办高等教育政策旨在引导民办高等教育的良性发展，伴随着民办高等教育的演进而调整。1949-1956年对民办高校实行公有化，民办高校整体“消失”。中国改革开放把市场“搞活”，促进了民办高校的发展。然而，法律的不完善制约着民办高校的发展，甚至造成民办高校发展的停滞。新《民办教育促进法》对民办高校实施营非分类管理，为营利性民办高校的发展带来了光明的前景。通过运用间断-平衡框架，分析民办高等教育政策的变迁，可以为政策的优化提供新思路。

Ensino de genética no Brasil: um panorama das concepções e estratégias didáticas
Authors: Lopes Eduarda da Silva , Da Costa Güllich Roque Ismael
Published: December 2020

O presente estudo descreve uma pesquisa qualitativa de caráter documental sobre as concepções e metodologias de Ensino presentes nos resumos publicados na seção de Ensino de Genética dos Congressos Brasileiros de Genética, organizados pela Sociedade Brasileira de Genética (SBG), entre os anos de 2012 e 2017. O texto divide-se em dois momentos: incialmente os 38 resumos foram separados em três categorias de análise, sendo as concepções de Ensino: técnico, prático e emancipatório/crítico. Observou-se que a perspectiva técnica do Ensino de Genética correspondeu a 67,2% dos resumos selecionados. Em seguida, verificou-se as metodologias presentes nesses resumos, aparecendo em maior destaque os jogos didáticos (23,7%). Diante da análise e do mapeamento realizado sobre as pesquisas voltadas ao Ensino de Genética, conseguimos compreender as concepções assim como as metodologias de Ensino que estão presentes nas pesquisas. Defendemos a ideia de que as metodologias e as concepções estejam em movimento, em transformação, sendo empregadas de acordo com o contexto escolar, a fim de um Ensino de Genética contextualizado, inovador e sobretudo, que possa ser cada vez mais crítico/emancipatório.
Los Objetivos de Desarrollo Sostenible y las capacidades tecnológicas
Authors: Mayer-Foulkes David , Serván-Mori Edson , Nigenda Gustavo
Published: December 2020

Para lograr los objetivos de desarrollo y salud sostenibles, es esencial incrementar las capacidades tecnológicas de las poblaciones más desfavorecidas. Entrado el siglo XXI, existen las tecnologías necesarias para ello. El déficit en capacidades tecnológicas se debe a la existencia de un gradiente tecnológico entre la producción de gran y de pequeña escalas, debido a la falta de incentivos para la innovación y la difusión en empresas y comunidades pequeñas. En estos ámbitos el cambio tecnológico, punto medular del desarrollo, es un bien público que la economía de mercado no provee eficientemente. Su provisión requiere la aplicación de políticas públicas de innovación y difusión tecnológicas. La reducción del gradiente tecnológico constituye, pues, parte medular de la Agenda 2030 para el Desarrollo Sostenible, de las Naciones Unidas, y la Agenda de Salud Sostenible para las Américas 2018-2030, de la Organización Panamericana de la Salud. Esto es aplicable, así mismo, al desarrollo de los sistemas de salud, que funcionan también como mecanismos de redistribución para romper las trampas de pobreza. Asimismo, las experiencias en esos sistemas tienen relevancia para aplicar políticas de incremento de capacidades tecnológicas que disminuyan la pobreza, mejoren los determinantes sociales de la salud y, con ello, reduzcan la magnitud de la trampa de desarrollo humano.

Possibilities of Graphic Ethnography
Authors: Sopranzetti Claudio , Fabbri Sara , Natalucci Chiara
Published: December 2020

Claudio Sopranzetti, Sara Fabbri, and Chiara Natalucci are the team behind the new graphic ethnography The King of Bangkok (University of Toronto Press 2021). The King of Bangkok tells the story of Nok, an urban migrant from Thailand’s northeastern region as he moves back and forth from his home village and attempts to build a life in the country’s capital across periods of massive economic growth and collapse and periods of democratic expansion, state violence, and political closure. Structured around a series of flashbacks, The King of Bangkok shows how these historical events shaped Nok’s life and how Nok’s life came to shape those events. The book was originally published in Italian (Add Editore, 2019) and was subsequently translated into Thai as Taa Sawaang (Awakening, อ่านอิตาลี 2020). In this interview we ask Claudio, Sara, and Chiara about their experience creating this text, its relationship with more traditional ethnographic genres of writing, and the effects their project has had in Thailand. We are delighted to feature a small section of the book following the interview.

From Synchronous Face-to-Face Group Work to Asynchronous Individual Work: Pivoting an Enterprise Modelling Course for Teaching during a COVID-19 Lockdown
Authors: Drechsler Andreas
Published: December 2020

This paper outlines the challenges faced in a particular instance of an enterprise modelling (EM) course that lost the ability to have face-to-face interactions and describes a solution that proved to be at least equally effective and appreciated when moved online. The revised course design is primarily driven by exercise and assignment work, provides course content in a ‘piecemeal’ fashion, and relies almost exclusively on asynchronous interactions. This paper distils the solution into specific design features of the revised course as well as more general design principles that can be applied to other EM courses (and potentially beyond).
Beyond Assessment: Assuring Student Learning in Higher Education.
Authors: Mabin Victoria , Marshall Stephen
Published: December 2020

Setting up an 'Assurance of Learning' (AoL) system in line with requirements for accreditation is generally perceived to be a challenging task in both theory and practice. This paper provides an overview of the AoL system developed by the Faculty of Commerce and Administration to meet the requirements for accreditation by the Association to Advance Collegiate Schools of Business (AACSB), and describes its rationale, results achieved to date, and current challenges. The Faculty's system draws on the use of graduate attributes (Barrie, 2004), constructive alignment (Biggs, 1999), quality systems (Deming, 1982) and Theory of Constraints (Goldratt, 1994). In particular, individual student assessment is used to provide programme-level assurance of learning of graduate attributes. AoL's focus on 'closing the loop' – using student cohort performance data to inform system level change so that more students achieve the overall programme-level learning goals – is illustrated through a number of examples. While AoL developments have been led largely by business schools, we argue that wider adoption would allow universities to back up their claims about their students' achievement of graduate attributes, moving towards assuring, not just assessing, student learning.

RESUMOO balanço de calor na interação oceano-atmosfera tem forte influência da temperatura da superfície do mar (TSM) e, portanto, pequenas variações podem levar a variações significativas nos fluxos de calor, os quais desempenham um papel importante nos sistemas climáticos. Excesso de calor armazenado nos oceanos vem causando aumentos na temperatura cujo desequilíbrio de energia torna-se uma das formas de quantificar a taxa de aquecimento global. Estudos recentes mostram que em 2019 ocorreu o maior aquecimento em todo período já registrado. Neste trabalho são investigadas tendências nas séries anuais e sazonais da TSM, em seis pontos ao longo da plataforma continental do sul do Brasil, Uruguai e Argentina, bem como, o número de ocorrência (Noc) de extremos acima do percentil de 90, utilizando-se dados de reanálise Era-Interin do European Centre for Medium-Range Weather Forecasts de 1979 a 2018. Testes estatísticos não-paramétricos de Mann-Kendall, declividade Sen e Pettitt foram utilizados para testar a estacionariedade e eventuais mudanças bruscas na média das séries temporais. Resultados da análise descritiva mostram picos nos valores máximos anuais a partir do ano 2000, assim como, tendências positivas nas anomalias e nos Noc de extremos. Os maiores valores de TSM foram verificados no verão (JFM), porém próximo ao sul do Brasil ocorreram, também, em abril e maio de 2018. Testes estatísticos confirmam tendências positivas e mudanças na média entre final de 1990 e início de 2000, principalmente na TSMMáx. Concluímos que no padrão de máximos da TSM na região de estudo ocorreu um aquecimento no período analisado.

A cidade de Juazeiro-BA destaca-se por ser um importante polo de desenvolvimento agrícola em bases irrigadas no Nordeste, no qual a distribuição sazonal da precipitação pluviométrica tem influência decisiva no contexto da relação saúde e saneamento em áreas urbanizadas, na agricultura familiar, no abastecimento de água de famílias isoladas e na economia dessa região. Assim, essa pesquisa tem como objetivo avaliar a distribuição das chuvas no município de Juazeiro-BA, analisando uma série diária de 32 anos de dados pluviométricos, calculando os valores anuais e sazonais do Índice de Concentração da Precipitação (ICP) e realizando um estudo de tendência da precipitação pluviométrica, a partir do método de Mann-Kendall. Os resultados revelaram que, em Juazeiro, o período chuvoso é bem definido, com os maiores índices de precipitação entre os meses de dezembro e março. O ICP anual tem o valor de 28,48 %, indicando alta irregularidade na distribuição das chuvas anuais, possibilitando a ocorrência de eventos extremos, tanto de inundações quanto de escassez hídrica. O teste de Mann-Kendall, para o período em estudo, apresentou tendência de diminuição da média pluviométrica anual em 7,51 mm, o que pode aumentar o déficit hídrico na região.Palavras-chave: Chuvas; Séries Climáticas; Concentração Pluviométrica; Mann-Kendall. Seasonal Variation and Trend in Rainfall in the Municipality of Juazeiro-BA A B S T R A C TThe city of Juazeiro-BA stands out for being an important agricultural development hub on irrigated bases in the Northeast, in which the seasonal distribution of pluviometric precipitation has a decisive influence in the context of the health and sanitation relationship in urbanized areas, in family agriculture, in water supplying of isolated families and the economy of that region. Thus, this research aims to assess the distribution of rainfall in the municipality of Juazeiro-BA, analyzing a daily series of 32 years of rainfall data, calculating the annual and seasonal values of the Precipitation Concentration Index (PCI) and conducting a rainfall trend study, using the Mann-Kendall method. The results revealed that, in Juazeiro, the rainy period is well defined, with the highest levels of precipitation between the months of December and March. The annual PCI has a value of 28.48 %, indicating a high irregularity in the distribution of annual rainfall, enabling the occurrence of extreme events, both floods and water scarcity. The Mann-Kendall test, for the period under study, presented tendency decrease of the annual rainfall average by 7.51 mm, which may increase the water deficit in the region.Keywords: Rainfall; Climate Series; Rain Concentration; Mann-Kendall.

Advances in technology have undoubtedly brought enormous benefits to society. On the other hand, these same advances bring new and even unknown impacts to the environment. When the theme is transportation systems, electric vehicles are the most modern and technological, being considered by the mainstream media as the most environmentally sustainable transportation model. However, little is discussed regarding the impacts and harms that are tied to this type of vehicles. In this way, this study aims at highlighting the main challenges and perspectives of the vehicular electrification technology, through a systematic review on the topic. The results obtained point out that electric cars may be responsible for the increase of eco-toxicity not only with respect to air quality, but also water and metal depletion. And, it also highlights, the existence of other technologies as alternatives to vehicle electrification. Perspectivas e Desafios da Eletrificação Veicular: Uma Revisão Acadêmica R E S U M OOs avanços da tecnologia vêm trazendo enormes benefícios para a sociedade, indubitavelmente. Por outro lado, esses avanços trazem consigo novos e até mesmo desconhecidos impactos ao meio ambiente. Quando o tema é sistemas de transportes, os veículos elétricos são o que há de mais moderno e tecnológico, sendo considerados pelas principais mídias como o modelo de transporte ambientalmente mais sustentável. No entanto, pouco se é discutido com relação aos impactos e malefícios atrelados a estes tipos de veículos. Desta forma, este estudo tem por finalidade destacar os principais desafios e perspectivas da tecnologia de eletrificação veicular, através de uma revisão sistemática sobre o tema. Os resultados apontam que os carros elétricos podem ser responsáveis pelo aumento da eco-toxicidade não apenas no que diz respeito à qualidade do ar e da água, mas também na depleção de metais. E, destaca a existência de outras tecnologias como alternativas à eletrificação veicular.Palavras-chave: Veículos Elétricos, Desafios, Perspectivas, Impacto Ambiental.
