como se fosse a crítica: uma correspondência para Ana Martins Marques
Authors: Belúzio Rafael Fava
Published: July 2021

Bilhete: Leitor, se quiser vasculhar essa carta, você precisará ter a permissão da Ana Martins Marques. Escrevi para ela pensando em conversar um pouco sobre como se fosse a casa (2017) e tentei abordar alguns assuntos que me chamam a atenção na poética da autora. Eu estava aqui, no Edifício JK, em Belo Horizonte, e fiquei comparando os textos da poetisa e determinados aspectos do prédio de Niemeyer, local em que Ana e eu, migrantes, moramos por algum tempo. Também fiquei refletindo sobre o modo de a escritora desenvolver a musicalidade nos enjambements de seus versos, além de notar que a sua obra mais recente está em diálogo com as anteriores A vida submarina (2009), Da arte das armadilhas (2011) e O livro das semelhanças (2015). Enfim, ainda há nessas páginas fotos pessoais e assuntos delicados. Conto com a sua discrição. Um abraço.
A praga escarlate e o vírus da linguagem
Authors: Carvalho André
Published: July 2021

: Este artigo discute A praga escarlate (The Scarlet Plague), novela publicada em 1912 pelo escritor estadunidense Jack London. A obra detalha um futuro alternativo em que o planeta foi devastado por uma pandemia e a população restante vive em condições próximas à barbárie. A obra é examinada em relação a teorias de contágio e é interpretada como uma instância exemplar das transformações intelectuais e políticas da chamada Era Progressista. Detalhamos como teorias da microbiologia e da epidemiologia influenciaram conceitos nascentes de multidão e cultura, particularmente em teorias nascentes de sociologia e comunicação. Argumentamos que a novela pode ser lida como uma reflexão sobre as atitudes e as ambivalências de uma classe de intelectuais reformistas da época, que buscava encontrar métodos e linguagens originais para representar a nova realidade social dos centros urbanos industrializados na passagem para o século XX.
Poesia esparsa, destino esparso. Leminski em Santa Catarina
Authors: Clesar Rosana , Wolff Jorge Hoffmann
Published: July 2021

Na contramão dos itinerários de artistas brasileiros que historicamente se dirigem ao eixo Rio-São Paulo, o presente trabalho resgata a relação do poeta Paulo Leminski (Curitiba, 1944-1989) com o estado de Santa Catarina, através de suas visitas para eventos literários, em três momentos: em 1976 em Florianópolis e Blumenau, e em 1985, novamente, na capital catarinense. O trabalho lança mão de documentos localizados em acervos públicos e particulares e em hemerotecas nacionais que permaneciam pouco ou nada estudados. Foram recuperados depoimentos, reportagens, ensaios, fotografias e poemas inéditos em livro que podem oferecer novas percepções a respeito de sua obra. A partir deste material esparso são apresentadas relações intelectuais também pouco exploradas, com destaque para a poesia corpórea do poeta Lindolf Bell (Timbó, 1938 - Blumenau, 1998).
O chamado órfico da literatura: as desastrosas imagens da impossibilidade na obra Moby Dick
Authors: Dos Santos Amaral Marcos Roberto
Published: July 2021

Com o intuito de problematizar as imagens que defletem a impossibilidade de a literatura chegar a um termo, figurando como escrita errante, inútil e sem-fim cotejaremos as vicissitudes de algumas particularidades da obra Moby Dick, de Melville. Nesse sentido, questionaremos, sob a perspectiva blanchotiana (2005; 2001; 1997; 1987), de que forma as imagens da impossibilidade figuram em torno do aniquilamento: do autor, tornado refém da própria escrita, que se absolutiza; da desordem do cânone clássico, diluído num discurso caótico e na fragmentação e dispersão da escrita, nos quais vozes, identidades e instituições desestabilizam-se enquanto totalidade teleológica e universal; e da rarefação das ideologias burguesas, relativizadas pela crítica da palavra útil e pela abertura da obra à escrita do anódino, desautorizado e sem-sentido.
Cleópatra e os antigos Césares sem a letra ‘o’, por Fulgêncio, o Mitógrafo: tradução lipogramática do Livro XIV da De aetatibus mundi et hominis
Authors: Santos Júnior Cristóvão José dos
Published: July 2021

Esta é a primeira tradução lipogramática do Livro XIV da obra De aetatibus mundi et hominis. Tal escrito é o mais antigo lipograma atestável, sendo atribuído ao autor norte-africano e tardo-antigo Fábio Plancíades Fulgêncio, o Mitógrafo, que teriavivido entre os séculos V e VI d.C. Nesta última seção, Fulgêncio descreve a vida de imperadores romanos a partir de sua óptica moral cristã sem empregar unidades lexicais que apresentem a letra ‘o’. Ressalte-se, por fim, que essa marca estilística foi cultivada no texto de chegada, proposto a partir da edição crítica estabelecida pelo filólogo latinista Rudolf Helm (1898), haja vista sua relevância para a História da Arte e para a tradição de Escrita Constrangida.

A voz do verme híbrido e transtemporal de Pedro Kilkerry
Authors: De Oliveira Leonardo Davino , Dos Santos Gabriel Costa Resende Pinto Bastos
Published: July 2021

Pedro Militão Kilkerry (1885-1917) é um poeta simbolista baiano pouco conhecido, pouco pesquisado, e definitivamente muito evitado por sua fama de “difícil”. Nosso trabalho concentra-se no poema “O verme e a estrela” de Pedro Kilkerry e na adaptação cancional do mesmo, levada a cabo por Cid Campos e registrada no disco A fábrica do poema (1994), de Adriana Calcanhotto, e no projeto verbivocovisual Poesia é risco (1995), de Augusto de Campos. O objetivo é elaborar uma reflexão sobre a potência viva e vivificante da voz e de sua vocoperformance, que expande o meramente gráfico para novas potências somente sugeridas e ocultas em estado-página, a partir de um poema tão extraordinário.
Comentários online e as noções de estereótipo e lugar no quadro da argumentação polêmica
Authors: Catelão Evandro de Melo , De Oliveira Amanda Bueno
Published: July 2021

Este estudo se debruça sobre uma análise descritiva de comentários online em uma publicação com temática homoafetiva no Instagram. Buscamos realizar um exame argumentativo dos dados utilizados pelos comentaristas em relação à presença e ao uso de estereótipos, lugares-comuns e as chamadas evidências comuns no interior de uma interação polêmica. Delimitamos um tipo de análise com noções e métodos da linguística de texto, ou mais particularmente, da Análise Textual/Discursiva (espaços textual e discursivo), assim como da Teoria da Argumentação no Discurso (delimitação dos tipos de dados utilizados) e da Análise do Discurso Digital (noções de tecnodiscurso e comentário online). Os comentários coletados apresentam características do que é definido como interação polêmica, ou seja, de uma argumentação envolta no dissenso. As análises permitem concluir que há uma forte tendência ao uso de argumentos com marcas estereotipadas ou como o que caracterizamos como evidências comuns, tanto em defesa quanto contra o tema da polêmica. Esse dado representa uma forte demarcação de espaço discursivo no momento de combate do ponto de vista e dos valores de grupos adversários.
Contemporâneos – o sertão, a literatura e a tragédia
Authors: Oliveira Viviane Cristina
Published: July 2021

Muitos são os sentidos possíveis, literais e literários, para a palavra sertão. Neste artigo, aciono especialmente um sentido topográfico mais geral, ligado à ruralidade, como destacado está em verbetes como o do dicionário Houaiss, para ensaiar uma leitura do caráter trágico de textos de autores contemporâneos, como Ronaldo Correia de Brito. É partindo do sertão como toponímia, física, subjetiva e imaginada, espaço marcante na ficção nacional, que no texto aqui apresentado se desdobram algumas considerações sobre a refiguração da tragédia na literatura brasileira contemporânea. Refiguração que possibilita a percepção de múltiplas e heterogêneas experiências que, no presente, embaralham corpos, narrativas, tempos e espaços, de forma a permitir novas miradas para conceitos polêmicos, e não menos interessantes, como literatura regional ou regionalista.
José de Alencar e a ruína das categorias
Authors: Da Silva Felipe Lima
Published: July 2021

O presente artigo propõe uma leitura do romance O Guarani, de José de Alencar, por meio de uma perspectiva retórica que permita compreender o enredo do livro pelos condicionamentos e pelas categorias vigentes no próprio século XVII, época em que se passa a história. Em oposição à leitura de visão nacionalista, propõe-se uma perspectiva que veja no romance um enredo tecido pelas categorias retórico-político-teológicas que, aparentemente, estavam em ruínas no romantismo oitocentista. A leitura apresentada busca dialogar com a crítica literária que observa no romance as categorias da política católica seiscentista na mesma medida em que dialoga com as leituras que consagram o autor como o maior indianista da literatura brasileira.

Published: July 2021

Salmonella typhi is a gram negative, rod shaped bacteria that features a polysaccharide capsule, flagella for motility and fimbria for adhesion to the epithelial cells of intestinal mucosa. The organism is responsible for causing enteric fever and in severe cases it leads to complications such as intestinal perforation which can lead to death. The mainstay of treatment of typhoid fever is antibiotic therapy but unfortunately the emergence of MDR (multidrug resistant) and XDR (extensively drug resistant) strains pose a major threat to the successful treatment of typhoid. Around 200,000 global deaths can be associated with typhoid and most cases are seen in low socioeconomic countries with inadequate healthcare infrastructure particularly those that are densely populated, among them Pakistan is considered as high-risk country according to WHO criteria. Prevention strategies include education of the masses regarding hand hygiene, cleanliness and consumption of clean food and water. In 2019 Pakistan encountered an epidemic of XDR typhoid and to control it, Government introduced typhoid vaccine in its nationwide vaccination program, and is hopeful that it will decrease the burden of disease on state and its citizens.

The intercropping method is one way to maximize plants and soil's utilization in a dry land. This study aimed to determine the cultivation (cropping methods and fertilization) that could increase mungbean grain yield in dry land in the dry climate of East Sumba, East Nusa Tenggara Province. The experiment was conducted at dry land in a dry climate in Laipori Village, Pandawai District, East Sumba Regency in 2017. The experiment was laid out in a split-plot design with four replications. The main plot was a cropping pattern, namely (1) intercropping mungbean with maize. Mungbean plant spacing was 30 cm ´ 20 cm, two plants per hole, and maize plant spacing was (50 cm ´ 50 cm) ´ 120 cm, one plant/hole and (2) mungbean monoculture with a plant spacing of 40 cm ´ 10 cm, two plants/hole. The subplot was dosage and type of fertilizer, namely (1) 150 kg Phonska/ha, (2) 5000 kg cow manure/ha, and (3) 75 kg Phonska + 2500 kg cow manure/ha. The mungbean variety used was Vima 1, and the maize variety was Bima. The results showed that intercropping mungbean with maize could increase the yield of mungbean seeds yield by 0,28 t/ha (51,85%) and increase the mungbean biomass by 0,31 t/ha (22,30%) compared to the monoculture system. Different types and dosages of Phonska inorganic fertilizer and cow manure did not cause differences in the mungbean yield.

The study of the influence of the temperature of polyethylene printing on the dimensional stability of samples obtained by the method of FDM printing has been carried out. It is shown that a change in the temperature of the nozzle from 200 to 260 °C leads to a decrease in the deviation from the plane by a factor of eight. In this case, the tensile strength remains practically unchanged, and the elongation increases by 30 %. It has been established by the methods of rheological and microstructural studies that the observed effect is associated with a change in the structure of polyethylene, which is initiated by an increased temperature of the printer's extruder head. It has been suggested that the likely reason for the change in the structure of polyethylene is a change in the course of the crystallization process due to partial thermal oxidative destruction of the polymer matrix in the extruder head of a 3D printer.

Published: July 2021

Traditional study has discovered that natural materials such as wood are scarce and that synthetic materials can serve as suitable substitutes. Polymer chemicals, plant materials, chemical compounds, inorganic compounds, and other corrosion inhibitors all use metals. When technology fails, corrosion is one of the most severe consequences, causing harm to the financial system, natural resources, and people's lives. Natural materials such as wood are scarce, according to traditional research, and synthetic materials may serve as suitable replacements. Polymers as corrosion inhibitors have piqued researchers' attention from both a theoretical and practical standpoint. It has been seen from the research that natural polymer inhibitors exhibits more than 90% efficiency and good surface cover on carbon steel surface. A summary of forms of corrosion, corrosion processes, and recent work on the application of polymer inhibitors on the basis of parameters such as cost, convenience of use, environmental impact, and reliability has been reviewed.

Background: Pigeonpea is second most important pulse crop grown after chickpea in India. Pigeonpea is versatile crop can be grown in vast agro climatic condition with low input. Although the yield is very less as compare to the potential yield, so we need to increase the yield of pigeonpea using modern techniques such as drip fertigation and mulching. Both these techniques are resource saving and realized maximum yield as compare to conventional practices. Methods: The experiment was laid out in factorial complete randomized block design with three replications. The experiment consisted of two levels of irrigation (0.50 CPE and 0.75 CPE) as one factor and three fertility levels (100% RDF,75% RDF and 50% RDF) as second factor and two levels of mulching (without mulching and with plastic mulching 25 micron) as third factor. Result: The results revealed that the combination of higher level of irrigation with 100 per cent RDF and with plastic mulching recorded significantly higher seed yield, water productivity and B.C ratio compared to the rest of the treatment combination.

The COVID-19 influenced global pandemic severely affected the market of small industries and had a deep impact on the agri economic of the farmer community across the globe. The main objective of this article is to emphasize on the influence of global pandemic with agriculture and food sector. The lockdown made ambivalent in agriculture, the point of concern is that, at the first phase of lockdown in India, Rabi crops are at harvest stage, due to the lockdown the breakdown of supply chain has been interrupted and left a noticeable impact on the marketability of agriculture crops even though it has registered moderate growth in terms of yield. At present globally mankind is experiencing the waves of pandemic and it caused significant loss to the yield of crops. If the situation continuous, the world is going to experience the hunger deaths. To overcome the issue discussed, agriculture sector needs to adapt new technologies, right from the cultivation, harvest and supply chain with marketing to bring the new normal life back to mankind. This is the right time to have transition from conventional agri practices to the technology invented smart agriculture. Indian agriculture sector should adapt and the former community need to be educated in applying ICT based smart agriculture practices such as utilization of automated machinery, AI (artificial intelligence) enabled cultivation methods, Internet of Things (IoT) and Wireless Sensor Networks based monitoring and maintenance of the agriculture practice. The application ICTs methods in agriculture practices facilitate to choose good quality seeds, optimum quantity of manures required for the enhanced crop yield, and direct monetary of the agriculture firm in order to show resilience to the global pandemic impact on agriculture sector. In the present review authors emphasised on various smart agriculture methods and their importance in promoting the agriculture practice as profitable venture and also how this ICT methods helps the sector to overcome the impact of global pandemic and to bring back the new normal life.

Published: July 2021

Background: Climate change is expected to be a major constraint for chickpea as it increases the frequency of drought and temperature extremes. The aim of this study was to investigate the effect of drought and heat stress conditions on chickpeas’ physical, quality and bioactive traits, along with antioxidant activity of five chickpea genotypes in normal and late sowning conditions. Methods: Field trials were carried out at Institute of Industrial and Forage Crops. All the five genotypes were planted at two different sowing dates, one during the normal sowing period (February 28, 2019) and one off-season (April 1, 2019) in order to achieve dry-heat conditions during the chickpea’s critical stages of off-season sowing. Result: Sowing period significantly affected cooking time and bioactive traits, resulted in decreased cooking time and increased bioactive traits values, in the later sowing period. Genotype’s effects were significant for all the traits studied. Amorgos appeared to be a promising variety with high nutritive value as it showed the highest values in terms of bioactive traits and antioxidant activity in both sowing periods, combined with low cooking time and high protein content at the off-season sowing.

Some characteristics of the proposed distributions as the joint survival function, hazard rate function, cross factorial moment and stress-strength parameter are also derived. The inferences for the parameters or even functions of the parameters of the models are obtained under a Bayesian approach. An extensive numerical application using simulated data is carried out to evaluate the accuracy of the obtained estimators to illustrate the usefulness of the proposed methodology. To illustrate the usefulness of the proposed model, we also include an example with real data from which it is possible to see that the proposed model leads to good fits to the data.

This study introduces a generalization of the odd power Cauchy family by adding one more shape parameter togain more flexibility modeling the complex data structures. The linear representations for the density, moments, quantile,and generating functions are derived. The model parameters are estimated employing the maximum likelihood estimationmethod. The Monte Carlo simulations are performed under different parameter settings and sample sizes for the proposedmodels. In addition, we introduce a new heteroscedastic regression model based on the special member of the proposedfamily. Three data sets are analyzed with competitive and proposed models.

The entomopathogenic fungus Paecilomyces fumosoroseus (common name: Isaria fumosorosea) can utilize to control white fly population. Bemisia tabaci or white fly has become key pest in soybean cultivation. It reported became resistance due to chemical pesticide. Some of new strain has been emerge as chemical pesticide resultant However, to develop P. fumosoroseus as biopesticide hide a problem. The environmental drought factor (temperature and water stress) become major problem. This research aimed to determine effect of environmental factor like temperature and water stress to growth and effectivity of P. fumosoroseus, due to selection an isolat were persist to drought factor. In this research has been used two different isolat of P. fumosoroseus, that is Wirowongso 1 isolat and Mumbulsari 5 isolates. This research had been conducted with five different treatments. First is a growth test under temperature stress, in vitro germination test under temperature stress and in vitro germination test under water stress, and virulence test under temperature and under water stress. The result showed that the increase a temperature and of water stress, directly make decreased of growth, germination and effectively. That effect has made different effect to growth, germination and effectivity on both isolat. The results showed that the isolat WR 1 test result showed the isolat WR 1 more persist to each drought factor. It became more valuable to develop as biopesticide among other.Keywords: Bemicia tabaci, germination, isolat, Isaria fumosorosea, in-vivo.

Hadirnya teknologi media baru membuat pola baru dalam ber-media, kemudahan akses dan fasilitas yang dihadirkan oleh teknologi baru membuat semua orang dengan sangat mudah memanfaatkannya, tidak terkecuali anak muda. Teknologi pada media baru dalam era ini sangat compatible dengan karakteristik anak muda zaman sekarang. Tak jarang anak muda sekarang menjadikan teknologi media baru menjadi acuan utama dalam preferensi sumber informasi. Remaja hidup dalam bukan realitas yang sebenarnya, sebab New media memberikan ruang pada remaja untuk memproduksi informasi “lain” selain dirinya, ada realitas baru yang diciptakan oleh remaja dalam ber-media. Teknologi New Media telah mengubah cara anak muda dalam akses waktu luang, serta perilaku dan pengalaman waktu luang mereka. Komputer, ponsel pintar dan tablet bersama dengan perangkat New Media lainnya telah menciptakan interaktivitas yang dimana ada sebuah layar yang menciptakan ruang bebas. Kemudahan fasilitas mampu memenuhi anak muda zaman sekarang bukannya tidak memiliki resiko, ketidakmampuan anak muda dalam menggunakan dan masalah penggunaan teknologi media baru merupakan hal yang tidak bisa dianggap remeh. Perubahan yang terjadi dalam aktivitas menggunakan media khususnya penggunaan media baru muncul di lingkungan keluarga pada anak muda, ada istilah domestifikasi, domestikasi dalam konteks ini mengacu pada teknologi dalam internal keluarga yang membantu menjalankan fungsinya dalam kehidupan sehari-hari dan mengubah budaya keluarga dan pola interaksi, keluarga juga dianggap sebagai penyumbang pemakaian teknologi media baru dikalangan anak muda. Hadirnya new media diharapkan mampu diimbangai dengan kemampuan berliterasi media pula. Literasi dalam ber-media setidaknya mampu mengarahkan remaja/anak muda dalam penggunaan teknologi Media baru.
Organ commercialism, trafficking and transplant tourism

The gap between demand and supply of organs continues to widen worldwide, encouraging transplant commercialism. While solid organ commerce is most prevalent in impoverished countries, commercialisation of body parts such as tissues is prevalent in economically developed countries. A number of international legal instruments and transplant societies define, condemn, and criminalise these practices and have issued statements related to organ commercialism. In contrast, limited attention has been paid to illicit and unethical activities associated with the procurement and clinical use of tissues. In India, The Transplantation of Human Organs (Amendment) Act, 2011, has taken multiple measures to combat organ and tissue commerce and as a result the number of such instances seems to be on the decline. However, the fight against unethical organ procurement through the internet and the social media is challenging and requires the cooperation of global bodies.
Rt-Qpcr Diagnostics: The “Drosten” Sars-Cov-2 Assay Paradigm

The reverse transcription quantitative polymerase chain reaction (RT-qPCR) is an established tool for the diagnosis of RNA pathogens. Its potential for automation has caused it to be used as a presence/absence diagnostic tool even when RNA quantification is not required. This technology has been pushed to the forefront of public awareness by the COVID-19 pandemic, as its global application has enabled rapid and analytically sensitive mass testing, with the first test targeting three viral genes published within days of the publication of the SARS-CoV-2 genomic sequence. One of those, targeting the RNA-dependent RNA polymerase gene, has been heavily criticised for supposed scientific flaws at the molecular and methodological level and this criticism has been extrapolated to doubts about the validity of RT-qPCR for COVID-19 testing in general. We have analysed this assay in detail and our findings reveal some limitations, but also highlight the robustness of the RT-qPCR methodology for SARS-CoV-2 detection. Whilst our data show that some errors can be tolerated, it is always prudent to confirm that primer and probe sequences complement their intended target as when errors do occur, they may result in a reduction in the analytical sensitivity. However, in this case it is unlikely that a mismatch will result in poor specificity or significant number of false positive SARS-CoV-2 diagnoses, especially as this is routinely checked by diagnostic laboratories as part of their quality assurance.
FEASIBILITY AND ISSUES OF RURAL TOURISM BASED ON INTER-INDUSTRY COOPERATION
Authors: Sakurai Seiichi , Teraoka Shingo
Published: July 2021

The study described herein was conducted to identify general aspects of rural tourism based on the Inter-Industrial Cooperation Project in Japan and to investigate factors and background obstacles to sustainable development of rural tourism management through collaborative organization of various actors. Most approved projects are engaged in producing and marketing local specialty goods. The numerous projects aiming at initiating tourism activities are extremely small. Some approved projects targeting tourism management have already been abandoned.  The authors conducted interview surveys to elucidate some typical cases, which elicited the following points about hindrances to sustainable development of rural tourism management based on the Inter-Industrial Cooperation Project: difficulty of maintaining collaborative networks among actors of various types; unexpected tourism-related risks; vulnerability to demands of tourism industry; and the mismatch between the system of national projects and needs for the practice of tourism activities. Results of two case studies underscored these obstacles. The authors finally described the role played by actors outside the rural village and local government officers for improving future collaboration projects.

Published: July 2021

This descriptive study was conducted to determine the coping strategies of farm laborers in San Jose, Occidental Mindoro towards farm mechanization. It was conducted at Barangay Central, San Jose, Occidental Mindoro, one of the top rice producing barangays in the province. The 123 of the 215 farm laborers listed in the different Kabesilya or farmers labor group were selected using simple random sampling. The farm laborers were engaged in planting and harvesting of rice for at least three years in Central, San Jose, Occidental Mindoro. The researcher used an interview schedule in gathering data. The study used descriptive statistics such as mean, frequency, and percentage. Pearson’s Product Moment Correlation was also used. Result shows that the farm laborers were in their middle aged, literate and with medium household size. The farm laborers generally “agree” that farm mechanization had affected their employment, food security level, education of children, monthly income, and agricultural production operations. The farm laborers “moderately practiced” the different coping strategies to meet the undesired effect of farm mechanization. Further, the “highly practiced” coping strategies were minimizing food expenses and seasonal migration of some household members to find odd jobs. Moreover, years spent in formal education and household size has a significant relationship on the extent of which farm laborers experience the effect of farm mechanization. Years spent in formal education have significant relationship on the coping strategies employed by farm laborers on advent of farm mechanization in the area.
