Shift to The Front II Komplek Sukamukti Banjaran Project is one of the projects implementedby one of the companies engaged in telecommunications. In its implementation, each projectincluding Shift to The Front II Komplek Sukamukti Banjaran has a time limit specified in thecontract. Project scheduling is an important role in predicting both the cost and time in aproject. Every project should be able to complete the project before or just in the time specifiedin the contract. Delay in a project can be anticipated by accelerating the duration of completionby using the crashing method with the application of linear programming. Linear programmingwill help iteration in the calculation of crashing because if linear programming not used,iteration will be repeated. The objective function in this scheduling is to minimize the cost.This study aims to find a trade-off between the costs and the minimum time expected tocomplete this project. The acceleration of the duration of this study was carried out using theaddition of 4 hours of overtime work, 3 hours of overtime work, 2 hours of overtime work, and1 hour of overtime work. The normal time for this project is 35 days with a service fee of Rp.52,335,690. From the results of the crashing analysis, the alternative chosen is to add 1 hour ofovertime to 34 days with a total service cost of Rp. 52,375,492. This acceleration will affect theentire project because there are 33 different locations worked on Shift to The Front II and if allthese locations can be accelerated then the duration of completion of the entire project will beeffective

Need for Assessing the Inhalation of Micro(nano)plastic Debris Shed from Masks, Respirators, and Home-Made Face Coverings During the COVID-19 Pandemic
Authors: Han Jie , He Shanshan
Published: August 2020

This urgent need, as we point out in the manuscript title, stems from the fact that a regulatory gap widely exists in current quality standards and regulations on masks and respirators. By surveying the relevant ASTM, NOISH, EU, China, and ISO standards, as listed in the manuscript, we found no regulation or recommendation pertinent to this type of respirable hazard. Non-medical substitutes, such as face coverings, are also subject to such risks if made with improper household materials.

There are numerous studies on assessing the filtration efficiency of masks, respirators, and recently, cloth face coverings (ACS Nano, 2020, 14, 6339; Nano Lett, 2020, 10.1021/acs.nanolett.0c02211). This particular issue, however, has been widely neglected by the scientific community. Studies on masks and respirators as a source of respirable debris were found to be anecdotal (Ann. Occup. Hyg. 1986, 20, 131−133). Recent discussions on disposable masks and respirators focused on their widespread use during the current pandemic and disposal into the environment (Sci Total Environ 2020, 737:140279; Waste Manage 2020, 108, 202-205).

By putting several top-selling medical face masks and N95 respirators under microscopes, we found plenty of micro(nano)plastic debris on their inner facings, with some appearing to be loosely attached while others still connected to their structural fibers. The two types of debris often appear in the same cluster with similar morphology and texture. Figure 1 in the manuscript shows examples of these, and we have submitted a file containing additional images with methods and QA/QC as further evidence.

With the novel coronavirus still looming in our communities, there is a strong ongoing demand for personal respiratory protection devices. Supported by the latest guidance from WHO, many regulatory bodies have made these a compulsory requirement for the public when using public transport, or in certain settings where it is difficult to maintain adequate physical distancing. Respirable hazards such as micro(nano)plastics in these, if pervasively exist, may pose a public health concern. Children, the elderly, and individuals having chronic respiratory diseases may be particularly sensitive to this type of inhalable contaminants. With a growing body of evidence on their adverse effects, micro(nano)plastics is an active research domain with a quickly expanding scope. Researchers studying their inhalation, via atmospheric or other anthropogenic sources, are now facing the reality that there is a piece of plastic garment on top of the mouth and nose of millions of people every day. With these becoming a necessity for many in their daily life and work, questions must be raised over this apparent regulatory gap concerning their long-term use safety. The current pandemic, if anything, should bring this particular issue under scrutiny.
Interfacial Electro-Epoxidation in Electrospray Ionization Mass Spectrometry for Simultaneous Analysis of Negatively and Positively Charged Unsaturated Glycerophospholipids
Authors: Tang Shuli , Fan Licheng , Cheng Heyong , Yan Xin
Published: August 2020

In this study, we developed an AC-induced interfacial electro-epoxidation reaction for localization of double-bonds in nega-tively and positively charged forms of lipids simultaneously. An AC voltage plays multiple roles in this method, including initiation of the electrochemical epoxidation of double-bonds in both charge states of lipids, and protonation and deprotona-tion of lipid for detection in both ion modes. The advantages of simultaneous detection of negatively changed and positively charged unsaturated lipids, voltage-controlled electrochemical derivatization, and the low sample consumption allow its wide applications in a broad range of lipid-related research.

Shalya Tantra is a significant branch of Ayurveda. The name of the sage-physician Susruta is well known in the field of surgery. Many surgical and para-surgical techniques have been described for the management of various diseases. Vrana is one of them which have been managed by a human being from starting of civilization. Under the circumstances, the first thing which the man came across was the injury from different sources which was causing Vrana (wound). The wound is very common in both developed and developing countries. It is a breach in the normal tissue continuum, resulting in a variety of cellular & molecular sequel. A wound is a major health problem because the incidence of severe complications is high & financial resources are limited. Vrana is an important chapter of Shalya Tantra due to its involvement in many surgical conditions. This, phenomena of Vrana is not only limited to the cutaneous lesion but may also extend up to muscles blood vessels, ligaments, bones, joints, visceral organs and other vital parts of the body. The diagnostic criterion has been dealt in a very detailed manner by Acharya Susruth. In this article, efforts have been made to throw light on the pathology of Vrana, its classification, diagnosis, and it’s healing.

Studying Bibliometrics-Based Heuristics (BBHs): A New Research Program on the use of Bibliometrics in Research Evaluation
Authors: Bornmann Lutz
Published: August 2020

How do decision makers in science use bibliometric indicators and how do they rely on the indicators? Could bibliometric indicators replace the decision makers’ judgments (partly or completely)? Bornmann and Marewski (2019) suggest that these and similar questions can be empirically answered by studying the evaluative use of bibliometrics within the heuristics research program conceptualized by Gigerenzer, Todd, and ABC Research Group (1999). This program can serve as a framework so that the evaluative usage can be conceptually understood, empirically studied, and effectively taught. In this short communication, main lines suggested by Bornmann and Marewski (2019) are summarized in a brief overview.

Science education has been identified as an effective instrument toward the attainment of goals for global competitiveness. Thus, science teachers need to be conversant with different strategies suited for the best classroom interaction. According to Sorden [1] pedagogy on technology integration creates contexts for authentic learning. New technologies when integrated in a meaningful ways will enhance the production of knowledge and the communication and dissemination of ideas. It is in this context why the researcher intended to determine the approaches and strategies utilized in technology oriented-science instruction. Descriptive research method was used in this study with researcher-made questionnaire as the main data gathering instrument which was complemented by interviews. Respondents were 35 science teachers from Oblates of Saint Joseph schools. Weighted mean was the statistical tools used to treat gathered data. Results revealed that science teachers often utilized discussion, collaborative, experiential, reflective, metacognitive and expository practices and approaches in technology-oriented science instruction. Results also indicated that the use of simulations and blended learning were moderately utilized in teaching science. Study recommended that science teachers should be provided with more in-service trainings and seminars relative to teaching-learning resources for technology oriented science instruction particularly on the use of simulations, and blended learning, and the resources for these should also be available for teachers use.

Delignification is a lignin degradation, a preliminary process in industries that used cellulose containing substrates. Sengon logs are often used for the material in pulp industry because it has high levels of cellulose and low level of lignin. The aim of this study was delignification of sengon logs by using T.versicolor. The methods used include observation growth of T.versicolor compared with Phanerochaete chrysosporium, the rate of of lignin degradation (black liquor), delignification of sengon logs using T.versicolor and the chemical assay of sengon logs before and after delignification. The results of this study showed that delignification by T.versicolor was faster compared to P.chrysosporium based on the rate of lignin degradation (black liquor). The result showed that delignification by T.versicolor at room temperature reduced lignin of sengon logs by 37.31% within 20 days. Chemical assay performed on delignified sengon wood showed decreased level of ethanol benzene, soluble extractive substances, holocellulose, and cellulose and an increase of hemicellulose level.

Published: August 2020

Ethanol is considered as the most promising alternative fuel, since it can be produced from a variety of agriculturally-based renewable materials, such as sugarcane bagasse. Lignocellulose as a major component of sugarcane bagasse is considered as an attractive renewable resource for ethanol production due to its great availability and relatively low cost. The major problem of lignocellulose is caused by its need for treatment to be hydrolyzed to simple sugar before being used for bioethanol production. However, pretreatment using acid as hydrolyzing agent creates some inhibitor compounds that reduce ethanol production because these compounds are potential fermentation inhibitors and affect the growth rate of the yeast. Reduction of these by-products requires a conditioning (detoxification and culture starter adaptation). Thus, the aim of this study was to evaluate bioethanol production by fermentation with and without detoxified sugarcane bagasse acid hydrolysate using adapted and non-adapted culture of C. tropicalis. According to this study, the highest ethanol amount was obtained about 0.43 % (v/v) with an ethanol yield of 2.51 % and theoretical yield of 4.92 % by fermentation of sugarcane bagasse hydrolysate with detoxification using the adapted strain of C. tropicalis at 72 hours fermentation time. Furthermore, the addition of 3 % glucose as co-substrate on detoxified-hydrolysate media only achieved the highest ethanol concentration 0.21 % after 24 hours fermentation with the ethanol yield 0.69 % and theoretical ethanol yield 1.35 %, thus it can be concluded that the addition of glucose could not increase the ethanol production.

Published: August 2020

Indonesia has about 450 frog species which is approximately 20% of frog species in the world. Among frog species found in Indonesia are Fejervarya limnocharis dan Limnonectes macrodon belonging to family Dicroglossidae. Frog skin secretion is considered to have a potency to be used as an alternative source of antibacterial agent against Streptococcus pneumoniae multidrug resistant (MDR). The aims of the present study were to analyze antibacterial activity of skin secretions of F. limnocharis and L. macrodon against S. pneumoniae multidrug resistant (MDR) and conduct molecular phylogenetic analysis of the frog used to ensure classification of frog species. The release of skin secretion was stimulated using epinephrine injection. Antibacterial activity of the skin secretions was tested using the well and paper disc methods. Results showed that skin secretions of F. limnocharis have antibacterial activity against S. pneumoniae multidrug resistant (MDR) SPN1307. The activity, however, was lower compared to that of chloramphenicol in both well and paper disc methods. On the other hand, skin secretions of L. macrodon failed to inhibit the growth of S. pneumoniae multidrug resistant (MDR) SPN1307. Molecular phylogenetic analysis was carried out on F. limnocharis based on DNA sequence of a partial fragment of mitochondrial cytochrome oxidase subunit I (COI) gene. Results showed that the frog F. limnocharis is closely related (97%) to Fejervarya sp from Bali. Skin secretions of F. limnocharis, therefore, has the potency to be developed as a source of antibacterial agents against S. pneumoniae multidrug resistant (MDR) SPN1307.

Capsules are very important in the packaging of pharmaceutical preparations. Commercial capsule shell is generally made of gelatin from cows and pigs. Alternatives to gelatin from non-animal raw materials can be obtained from polysaccharides like starch and carrageenan. The purpose of this study was to obtain the optimum formula between amylopectin and carrageenan as a raw material subtitute for gelatin capsule shell. Program Design Expert 7.0.0 (trial version) with Response Surface Methodology (RSM) Central Composite Design was used to optimize formula with three variable factors and three response variables. Based on the analysis by determining the adjusted range, program recommends 29 optimization solution with desirability value 1. Formula 6 and 28 was selected for validation with factors 1,01% of amylopectin, 1.01% of carrageenan, 2.17% of glycerin (formula 6) and 3.00% of amylopectin, 2.00% of carrageenan, 2.90% of glycerin (formula 28). Prediction response value was 12.94% of moisture content, 6.35% of ash content (formula 6) and 12.99% of moisture content, 8.67% of ash content (formula 28). Validation result value was 21.45% of moisture content, 7.58% of ash content, 6.12 minutes of solubility in water (formula 6) and 17.67% of moisture content, 7.78% of ash content, 9.30 minutes of solubility in water.

Authors: Rahmawati Fri , Bintang Maria , Artika I Made
Published: August 2020

Geranium homeanum Turez is a herbaceous plant used as an empirical medicine. This research was carried out to test the antibacterial activity and determine minimum inhibition concentration (MIC) to Staphylococcus aureus and Pseudomonas aeruginosa with agar diffution method and phytochemical analysis of geranium leaves  by Harbone method. The young and old geranium leaves were blended then filtrated. The obtained filtrate was divided into two parts, one part heated by autoclave and the other was unheated. Each filtrate was tested against to Staphylococcus aureus and Pseudomonas aeruginosa. Geranium leaves filtrate having the highest antibacterial activity was heated at 500C until it  become dry powder.  The powder was used to measure MIC and phytochemical analysis.The results showed that the antibacterial activity of young leaves filtrate was higher than the old leaves filtrat, and the unheated leaves filtrate was higher than heated filtrate one. MIC of S. aureus and P. aeruginosa, were as follows 15 mg/ml and 20 mg/mL respectively. The antibacterial activity of powder geranium’s leaves  filtrate was weaker than 100 µg/mL ampicilline. Phytochemical analysis of geranium leaves showed positive contents of alkaloid and triterpenoid.
Jornalismo, ação racional conforme os fins e os valores
Authors: Da Silveira Fonseca Virginia Pradelina
Published: August 2020

A partir de uma concepção sociológica de extração weberiana, este artigo propõe uma reflexão sobre o jornalismo contemporâneo – concebido como ação racional em relação aos fins e racional em relação aos valores. Trata, portanto, de tema que se situa na interface entre a sociologia e a ética. Para isso, primeiramente, faz-se uma reflexão sobre o jornalismo como instituição. A seguir, apresenta-se a tipologia concebida por Max Weber para classificar as ações sociais. Por fim, com essa essa perspectiva teórica, argumenta-se em favor da ideia de que o jornalismo é uma ação racional que tanto persegue fins quanto age guiado por valores.
A linguagem gráfica de quem não vê: primeiros resultados empíricos
Authors: Santos Marcelo
Published: August 2020

Este artigo apresenta os primeiros resultados empíricos de projeto de pesquisa iniciado no ano de 2008, dedicado a investigar a produção de imagens por pessoas cegas. Há duplo objetivo: de um lado, questionar certos cânones da linguagem visual, evidenciando que vários dos seus princípios são apreendidos sem o auxílio da visão, não sendo, pois, exclusivamente característicos da visualidade; de outro lado, busca-se propor metodologias para a construção de imagens táteis, acessíveis bilateralmente a deficientes visuais e videntes. Os dados aqui exibidos foram gerados em estudo qualitativo realizado com um único sujeito cego. Este foi convidado a desenhar representações imagéticas, diagramáticas e metafóricas, interpretadas neste escrito com o auxílio da semiótica peirceana.
Afetos. Estudos Queer e Artifício na América Latina
Authors: Lopes Denilson
Published: August 2020

Buscamos um diálogo entre a discussão sobre afetos como proposta por Deleuze e Guattari e os estudos queer. Deleuze e Guattari, claramente defendem uma compreensão da obra de arte como blocos de sensações, formados por afetos e perceptos. Por sua vez, em obras recentes nos estudos queer em língua inglesa, o termo afeto aparece sem uma clara definição mas como uma estratégia para ir além de uma política de identidades e diferenças, Nossa proposta é que este dialogo pode encontrar uma resposta a este diálogo na genealogia de produção latino-americana centrada no artifício, dando especial ênfase. Como forma de comprovar a rentabilidade da aproximação entre estudos queer e artifício a estética da comunicação e os estudos da arte, faremos uma breve análise do filme Canto de Outono (2014) de André Antonio a partir de uma segunda forma do artifício: o dândismo.
A revolução será memetizada: engajamento e ação coletiva nos memes dos debates eleitorais em 2014
Authors: Chagas Viktor , Santos João Guilherme Bastos
Published: August 2020

O presente artigo tem como proposta desenvolver

uma reflexão sobre a relação entre engajamento

político, conversação informal e ação coletiva através

da brincadeira política (political play). O objetivo é

compreender um tipo particular de informação política

que circula nas mídias sociais, os memes de internet.

Dando sequência a uma agenda de investigações mais

ampla, este trabalho pretende analisar um conjunto de

73 imagens pertencentes a uma amostra original de 599

memes coletados durante o debate eleitoral transmitido

pela Band, em 2014. Em comum, todas essas imagens

foram publicadas no Twitter e apresentam fotografias

de uma televisão que exibia o debate. Interessa-nos

perceber em que medida é possível (1) qualificar essas

imagens como meme político, (2) caracterizá-las como

uma ação coletiva baseada na conversação informal,

e (3) identificar qual é o posicionamento político

predominante expresso por elas. Para dar conta dessas

questões, empreendemos uma análise de conteúdo

conjugada a uma avaliação qualitativa desses materiais.

Os resultados apontam para a necessidade de

repensarmos a conexão entre engajamento cívico e ação

política a partir da perspectiva do envolvimento casual

do cidadão médio com a política na internet.
Entre o rádio e a televisão: gênese e transformações das novelas brasileiras
Authors: Vicente Eduardo , Soares Rosana
Published: August 2020

Este artigo oferece um olhar sobre a radionovela no Brasil e as relações que se estabeleceram entre esse gênero e o das telenovelas. Inicialmente, apresentaremos aquelas que consideramos as duas tendências principais da ficção radiofônica no país: uma mais comercial, ligada ao melodrama e de caráter conservador, outra realista e politicamente engajada. Depois, discutiremos como essa segunda tendência, embora menos presente no rádio, foi de grande importância no desenvolvimento da telenovela. Finalmente, proporemos que a telenovela tornou-se a principal referência para a atualização da linguagem das radionovelas no projeto de produção desenvolvido pela SSC&B Lintas durante os anos 1980.

As interconexões entre violência e juventude, recebem assim um olhar tanto local quanto transnacional.
Nova Orleans não é aqui?
Authors: Fernandes Cíntia Sanmartin , Herschmann Micael Maiolino
Published: August 2020

Tomando especialmente como referência não só as obras de Negus, Maffesoli, Deleuze, Guattari, Straw e Bourdieu, mas também o estudo realizado em 2011 e 2012 (que consistiu em levantamento de matérias veiculadas na imprensa tradicional e alternativa nos últimos dois anos, a organização de entrevistas semiestruturadas com os atores, bem como de trabalho de campo executado em lugares estratégicos), busca-se avaliar neste trabalho: por um lado, se efetivamente nos últimos anos, vem se consolidando no Rio de Janeiro uma cena do jazz; e, por outro, se a “musicabilidade” e a “cultura das ruas” continuam promovendo grande mobilização social nesta cidade.

Sons urbanos e suas escutas através do cinema
Authors: Da Costa Fernando Morais
Published: August 2020

Este trabalho pretende analisar as possibilidades de representação dos ambientes sonoros urbanos pelo cinema. Para tanto, nos detemos, em uma primeira seção, nas chamadas “sinfonias de cidades”, filmes produzidos na passagem do cinema mudo para o cinema sonoro. Em um segundo momento, fazemos uma ponte com o cinema contemporâneo, analisando filmes nos quais a representação do espaço de determinadas cidades é central para as respectivas tramas. Em todos os filmes analisados, sendo-nos aqui indiferente a época em que foram produzidos, nos interessa pensar a parte sonora da representação, ao mesmo tempo em que podemos pensar como as escutas de tais filmes podem

provocar no espectador uma reflexão sobre o modo

com o qual ele se relaciona com os sons que o circundam no cotidiano urbano.

Pela adoção da perspectiva da pertinência em pesquisas comunicacionais
Authors: De Carvalho Carlos Alberto , Lage Leandro
Published: August 2020

Este artigo, de natureza ensaística, propõe a noção de pertinência como elemento balizador em pesquisas comunicacionais. O ponto de partida é que se, há pouco tempo, desafios como a definição do “objeto da comunicação” pareciam indicar os principais percalços para as pesquisas comunicacionais, hoje é a escolha dos melhores caminhos metodológicos a trilhar que permanece em aberto. Se à primeira vista, no entanto, um titubear metodológico pode parecer negativo, visto sob outro prisma, o da riqueza e diversidade das pesquisas comunicacionais, as questões de método aparecerão positivamente como o amadurecimento da área, inclusive quanto a quais são seus “objetos”, afinal, múltiplos e exigindo variadas abordagens metodológicas. A noção de pertinência que aqui desenvolvemos deve ser entendida como parte do esforço metodológico de compreensão da comunicação e suas problemáticas, a partir de três dimensões interconectadas: teórica, empírica e analítica.

Entre mundos: um encontro com o outro na tessitura da narrativa jornalística
Authors: Dionízio Priscila Martins
Published: August 2020

O espaço mediático se constitui como palco privilegiado de trocas simbólicas e compartilhamento de sentidos na sociedade contemporânea. A atividade jornalística, prática

discursiva componente desse espaço, nos coloca em contato com diferentes povos e culturas, tecendo narrativas e figuras de alteridade. É para tais narrativas que nosso trabalho se volta, com o objetivo de pensar a relação desenvolvida com a diferença no processo de produção do jornalismo. Trabalhamos uma série de reportagens chamada Nova África, exibida pela TV Brasil, e buscamos perceber a dinâmica instaurada entre a enunciação jornalística e a intervenção dos entrevistados,

no processo de constituição de sentidos da série. Ao olhar para a participação dos entrevistados, indagamos se o jornalismo consegue acolher as marcas do outro quando fala sobre ele.

Noite e Neblina: um livro sobre um filme na história
Authors: Blank Thais Continentino , Machado Patricia Furtado
Published: August 2020

O livro Nuit et brouillard, un film dans l’histoire (2007), da historiadora e professora da Universidade Paris I, Sylvie Lindeperg, mapeia os diferentes caminhos percorridos pelo documentário Noite e neblina (1956), de Alain Resnais. Enfatizando que as imagens de arquivo não devem ser entendidas como prova factual da história, mas como documentos em constante devir, Lindeperg retraça o percurso das imagens retomadas por Resnais. Ao longo das 283 páginas do livro, a pesquisadora realiza uma investigação minuciosa sobre o processo de realização da obra e sobre os diferentes olhares portados ao longo do tempo sobre as imagens que compõem o documentário. Explorando as relações entre cinema, história e arquivo, Lindeperg elabora um método de análise que permite pensar o gesto de retomada de imagens do passado, para além do filme Noite e neblina.
