ABSTRACT
The purpose of this study was to determine the effect of Hormax and NPK Mutiara (16:16:16) on sweet potato plants. The design used in this study was a Factorial Complete Randomized Design consisting of two factors. The first factor is Hormax (H) at doses of 0, 1, 3, and 5 ml per liter of water while the second factor is NPK Mutiara (16:16:16) (N) with concentrations of 0, 3.15, 6.3, and 9.45g per plant. The parameters observed were the number of crop tubers (tubers), tuber weight per plot (g), tuber weight per tuber (g), tuber weight per plant (g), wet pruned weight (g), harvest index. The last observation data were analyzed statistically and continued with a BNJ follow-up test at the 5% level. The results showed that the interaction of giving Hormax and NPK Mutiara (16:16:16) significantly affected the number of tubers per plant, tuber weight per plot, tuber weight per fruit, weight. The best treatment is in the combination of H2N2 fertilizer concentration of 3 ml/liter of water and 6.3 g / plant. The main influence of hormax is evident on the parameters of the number of tubers per plant, tuber weight per plot, tuber weight per tuber, tuber weight per plant, wet perched weight, harvest index, the best treatment of 3 ml per liter of water (H2). The main effect of NPK Mutiara fertilizer (16:16:16) is real on the parameters of the number of tubers per plant, tuber weight per plot, tuber weight per fruit, tuber weight per plant, wet perched weight, harvest index, best treatment ie 6.3 g per plants (N2).

ABSTRACT
The purpose of this study was to determine the use of Ageratum by planting among the main plants of cayenne pepper as an effort to control aphids. The design used in this study is the One-way Anova Design (one-lane design), which is planting Ageratum on a chili plant plot combined with ageratum with various densities consisting of 7 experimental treatments, namely: A = Without Ageratum., B = Two clumps / plot, C = Four clumps / plot, D = Six clumps / plot, E = Eight clumps / plot, F = Ten clumps / plot, G = Twelve clumps / plot. Each experimental unit contained 4 chili plants and 2 plants were sampled, making a total of 112 plants and a total of 336 Ageratum plants. The results showed that the planting of Ageratum conyzoides influenced plant height, flowering age, harvest age and fruit weight per plant. The best treatment results in treatments without planting Ageratum (A).The aphids population decreases with the increasing population of Ageratum per plot. planting Ageratum affects the number of pests of each species and the percentage of cayenne pepper affected by the virus is getting lower with increasing population Ageratum per plot. The treatment of Ageratum plants on cayenne pepper plants can control pests and diseases but reduce production.

ABSTRACT
The purpose of this study is to determine the effect of interaction and the main influence of vermicompost and NPK Pearl 16:16:16 on the growth and yield of celery plants. This research was carried out for four months, from August to November 2018. This research used a factorial completely randomized design (RAL) consisting of two factors, where the first factor was vermicompost fertilizer (K) consisting of 4 levels, namely 0, 60, 80, 100 g / polybag and the second factor is NPK Pearl 16:16:16 (N) fertilizer consisting of 4 levels, 0, 0.8, 1.6, 2.4 g/polybag. The observation parameters in this study were plant height (cm), relative growth rate (g), root volume (cm3), number of tillers, number of midribs, wet weight of crop (g), and age of harvest (days). The last observation data were statistically analyzed and continued with a BNJ follow-up test at the 5% level. The results showed that the interaction between vermicompost and NPK Pearl 16:16:16 fertilizer significantly affected plant height from week two to week seven, the relative growth rate in the first week, root volume, number of tillers, number of fronds and wet weight per plant. The best treatment is K3N3 (K3 vermicompost fertilizer = 100 g /polybag and NPK Pearl 16:16:16 N3 = 2,4 g/polybag), but it has no significant effect on the age of harvest and the main effect of vermicompost and NPK Pearl 16:16: 16 significantly affected plant height, relative growth rate, root volume, number of tillers, number of midribs and wet weight of the crop, with the best treatment being K3 (vermicompost fertilizer 100 g/polybag) and N3 (NPK Pearl 16:16:16 2,4 g/polybag).

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.

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.
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.

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.

Background: Cesarean section (CS) rate has increased rapidly over the past two decades in world. It is serious concern for public health experts globally. Various medical and non-medical factors, such as maternal socio-demographics, are found to be responsible for this upsurge. Like in other countries, the rate of caesarean sections has increased in Nepal as well. Therefore, there is a need to investigate the factors behind this increase.
Objectives: To identify the factors associate for caesarean section among mothers attending at teaching hospital, Chitwan
Methods: A cross sectional analytical study was conducted using total enumerative sampling technique in the maternity ward of Chitwan Medical College Teaching Hospital. Interview was done with closed ended Questionnaire for data collection, a total number of 139 mothers after 24 hours cesarean section (CS).
Results: The study shows that, nearly three- quarters (71.2%) of CS were performed as an emergency. There are mainly fetal, maternal and placental indication for cesarean section. The most frequent indications were: previous cesarean section (22.3%), thick Meconium stained liquor (12.2%), fetal distress (10.6%) and oligohydramnios (7.2%).

OBJECTIVE
Arteriovenous malformations (AVMs) present no pathologic tissue, and radiation dose is confined in a clear targeted volume. The authors retrospectively evaluated the role of the biologically effective dose (BED) after Gamma Knife radiosurgery (GKRS) for brain AVMs.

METHODS
A total of 149 consecutive cases of unruptured AVMs treated by upfront GKRS in Lille University Hospital, France, were included. The mean length of follow-up was 52.9 months (median 48, range 12–154 months). The primary outcome was obliteration, and the secondary outcome was complication appearance. The marginal dose was 24 Gy in a vast majority of cases (n = 115, 77.2%; range 18–25 Gy). The mean BED was 220.1 Gy2.47 (median 229.9, range 106.7–246.8 Gy2.47). The mean beam-on time was 32.3 minutes (median 30.8, range 9–138.7 minutes). In the present series, the mean radiation dose rate was 2.259 Gy/min (median 2.176, range 1.313–3.665 Gy/min). The Virginia score was 0 in 29 (19.5%), 1 in 61 (40.9%), 2 in 41 (27.5%), 3 in 18 (12.1%), and 4 in 0 (0%) patients, respectively. The mean Pollock-Flickinger score was 1.11 (median 1.52, range 0.4–2.9). Univariate (for obliteration and complication appearance) and multivariate (for obliteration only) analyses were performed.

RESULTS
A total of 104 AVMs (69.8%) were obliterated at the last follow-up. The strongest predictor for obliteration was BED (p = 0.03). A radiosurgical obliteration score is proposed, derived from a fitted multivariable model: (0.018 × BED) + (1.58 × V12) + (−0.013689 × beam-on time) + (0.021 × age) − 4.38. The area under the receiver operating characteristic curve was 0.7438; after internal validation using bootstrap methods, it was 0.7088. No statistically significant relationship between radiation dose rate and obliteration was found (p = 0.29). Twenty-eight (18.8%) patients developed complications after GKRS; 20 (13.4%) of these patients had transient adverse radiological effects (perilesional edema developed). Predictors for complication appearance were higher prescription isodose volume (p = 0.005) and 12-Gy isodose line volume (V12; p = 0.001), higher Pollock-Flickinger (p = 0.02) and Virginia scores (p = 0.003), and lower beam-on time (p = 0.03).

CONCLUSIONS
The BED was the strongest predictor of obliteration of unruptured AVMs after upfront GKRS. A radiosurgical score comprising the BED is proposed. The V12 appears as a predictor for both efficacy and toxicity. Beam-on time was illustrated as statistically significant for both obliteration and complication appearance. The radiation dose rate did not influence obliteration in the current analysis. The exact BED threshold remains to be established by further studies.
