A Topological Proof for a Version of Artin’s Induction Theorem
Authors: Saadetoğlu Müge
Published: October 2022

We define a Euler characteristic χ(X,G) for a finite cell complex X with a finite group G acting cellularly on it. Then, each Ki(X) (a complex vector space with basis the i-cells of X) is a representation of G, and we define χ(X,G) to be the alternating sum of the representations Ki(X), as elements of the representation ring R(G) of G. By adapting the ordinary proof that the alternating sum of the dimensions of the chain complexes is equal to the alternating sum of the dimensions of the homology groups, we prove that there is another definition of χ(X,G) with the alternating sum of the representations Hi(X), again as elements of the representation ring R(G). We also show that the character of this virtual representation χ(X,G), with respect to a given element g, is just the ordinary Euler characteristic of the fixed-point set by this element. Finally, we give a topological proof of a version of Artin’s induction theorem. More precisely, we show that, if G is a group with an irreducible representation of dimension greater than 1, then each character of G is a linear combination with rational coefficients of characters induced up from characters of proper subgroups of G.

Published: October 2022

Improving the signal-to-noise ratio (SNR) by amplifying the outputting signal or reducing nonspecific binding (NSB) are the key techniques in multiple immunoassay. Aiming at these issues, this paper presents an improved multiple indirect competitive immune surface-enhanced Raman scattering (ci-SERS) assay for the rapid screening of highly toxic rodenticides in food and biological samples, which ensured remarkable accuracy, ultra-sensitivity and reproducibility. The non-fouling polymer brush grafted magnetic beads (the MB@P-CyM) were prepared as multiple competitive recognition substrates after conjugating triplex haptens (the MB@P-CyM-hap). It was demonstrated that the particular 3D hair-like structures of P-CyM not only facilitate conjugate high-density hapten but reduce the steric hindrance from SERS probes recognition, thus enhancing SNB. On the other hand, Au nanoflowers (AuNFs) of high SERS activity were synthesized using a simple one-pot hydrazine reduction. For simultaneously detecting three highly toxic rodenticides, i.e., diphacinone (DPN), bromadiolone (BRD) and tetramine (TET), the obtained AuNFs were fabricated as a SERS-encoded nanoprobe cocktail after successively labeling mono-antibodies/Raman probes. By integrating the MB@P-CyM-hap with the SERS-encoded cocktail, a highly sensitive multiple SERS assay was achieved in less than 2 h with a limit of detection of 0.62 ng mL−1 for BRD, 0.42 ng mL−1 for TET and 1.37 ng mL−1 for DPN, respectively. The recoveries of these rodenticides in spiked food and biological samples were determined and ranged from 72 to 123%. Above all, the proposed modifications show remarkable improvements for high efficient multiple chemical toxin immunoassay.

Authors: Abdellatif Asmaa , Ghamry Essam , Sobh Mohamed , Fathy Adel
Published: October 2022

The current work makes use of the geometrical configuration of the two lower-altitude Swarm satellites (Swarm A and C), moving side by side with a longitudinal distance of 1.4°, to estimate a two-dimensional (2D) model of the lithospheric magnetic anomaly field over Egypt using gradient data. The gradient in both the north–south and the east–west directions have been inverted using the weighted damping least-squares fit technique to estimate the best model coefficients of the 2D model. The best model coefficients have been obtained under the expansion of the Legendre polynomial from degree n = 7 to n = 56. Results showed that the gradient of the field in the north–south direction is always much smoother than that in the east–west direction. The noise in the east–west direction is attributed to the different environmental conditions surrounding both satellites. The modeled field always showed smoother variations than the observed data, even for the horizontal components (Bx and By).

Vaccination with live attenuated vaccines is a key element in the prevention of lumpy skin disease. The mechanism of virus attenuation by long-term passaging in sensitive systems remains unclear. Targeted inactivation of virulence genes is the most promising way to obtain attenuated viruses. Four virulence genes in the genome of the lumpy skin disease virus (LSDV) Dermatitis nodulares/2016/Atyrau/KZ were sequentially knocked out by homologous recombination under conditions of temporary dominant selection. The recombinant LSDV Atyrau-5BJN(IL18) with a knockout of the LSDV005, LSDV008, LSDV066 and LSDV142 genes remained genetically stable for ten passages and efficiently replicated in cells of lamb testicles, saiga kidney and bovine kidney. In vivo experiments with cattle have shown that injection of the LSDV Atyrau-5BJN(IL18) at a high dose does not cause disease in animals or other deviations from the physiological norm. Immunization of cattle with the LSDV Atyrau-5BJN(IL18) induced the production of virus-neutralizing antibodies in titers of 4–5 log2. The challenge did not cause disease in immunized animals. The knockout of four virulence genes resulted in attenuation of the virulent LSDV without loss of immunogenicity. The recombinant LSDV Atyrau-5BJN(IL18) is safe for clinical use, immunogenic and protects animals from infection with the virulent LSDV.

Peptides constitute an alternative and interesting option to develop treatments, vaccines, and diagnostic tools as they demonstrate their scope in several health aspects; as proof of this, commercial peptides for humans and animals are available on the market and used daily. This review aimed to know the role of peptides in the field of veterinary diagnosis, and include peptide-based enzyme-linked immunosorbent assay (pELISA), lateral flow devices, and peptide latex agglutination tests that have been developed to detect several pathogens including viruses and bacteria of health and production relevance in domestic animals. Studies in cattle, small ruminants, dogs, cats, poultry, horses, and even aquatic organisms were reviewed. Different studies showed good levels of sensitivity and specificity against their target, moreover, comparisons with commercial kits and official tests were performed which allowed appraising their performance. Chemical synthesis, recombinant DNA technology, and enzymatic synthesis were reviewed as well as their advantages and drawbacks. In addition, we discussed the intrinsic limitations such as the small size or affinity to polystyrene membrane and mention several strategies to overcome these problems. The use of peptides will increase in the coming years and their utility for diagnostic purposes in animals must be evaluated.

Published: October 2022

The summer maize-winter barley (or wheat) rotation system is a conventional farming method in coastal areas of east China. However, researchers have paid little attention to the increasing soil degradation after successive crop rotation in coastal saline agriculture. In the current study, a two-year field experiment was conducted to investigate the changes in soil physio-chemical properties and crop grain yields under the maize-barley rotation system. Wheat straw derived biochar (BC) was applied to topsoil (0~20 cm) at four different rates (0, 7.5, 15 and 30 Mg ha−1) before summer maize cultivation, and no biochar was added in the cultivation of the winter barley. Bulk density (BD), water holding capacity (WHC), water stable aggregate (WSA), soil electrical conductivity (EC), pH (1:5 water w/v) and soil organic carbon (SOC), at the harvesting time of maize and barley, were analyzed. The application of biochar increased WHC and macro-aggregate (>2 mm) content after barley harvest. Soil EC was mainly affected by the rain during maize cultivation and increased only slightly under BC treatments. However, no difference in EC was found among all treatments after barley harvest. The application of BC at 30 Mg ha−1 increased the maize yield by 66% but produced no difference in the barley yield. We concluded that biochar could be an effective option to mitigate soil degradation and improve crop productivity in coastal saline agriculture.
Temperature Estimation of a Deep Geothermal Reservoir Based on Multiple Methods: A Case Study in Southeastern China
Authors: Lin Wenjing , Yin Xiaoxiao
Published: October 2022

Estimating deep geothermal reservoir temperatures is an essential mission of geothermal exploration and development. The thermal reservoir temperature estimated directly using geothermometry without comparative analysis is often far from the actual temperature. In this paper, taking the typical geothermal systems in the Xiamen Island–Zhangzhou area of southeastern China as an example, different methods such as a water–rock equilibrium analysis, SiO2 geothermometer, multi-mineral equilibrium diagram, and silica-enthalpy mixing model are used to make a quantitative and qualitative analysis of the chemical equilibrium of minerals and fluids in the geothermal system. Finally, the applicability of different methods was compared and analyzed, and the geothermal reservoir temperature was estimated using the appropriate method. The results show that the calculated results of the Si-enthalpy mixing model of a typical geothermal system in southeastern China are significantly high. At the same time, the SiO2 geothermometer (without vapor loss), which is closest to the results of the multi-mineral equilibrium diagram, was chosen as the geothermal reservoir temperature of the geothermal system in the study area. This study can provide a reference for the future selection of methods of deep geothermal reservoir temperature estimation in similar areas.
Introducing a Framework for Analyzing Weaknesses in Institutional Service Delivery and the Human Rights to Water and Sanitation: Case Studies from the Democratic Republic of Congo, Haiti, Mozambique, and Niger
Authors: Borja-Vega Christian , Grabinsky Jonathan , Kløve Eva
Published: October 2022

This article discusses how weaknesses in the governance of the water, sanitation, and hygiene (WASH) sector may present barriers to the assurance of human rights to WASH. The analytical framework in this article involves four key actors involved in the service-delivery process, operating across a three-way accountability connection linking the State, service providers, and citizens. The framework, drawn from the World Bank’s 2004 World Development Report, is applied to the following countries: the Democratic Republic of Congo, Haiti, Mozambique, and Niger. The findings suggest that breakdowns in provision can be strongly linked to disruptions in the accountability association between the State and WASH providers. Informed by the human-rights literature, suggestions are made as to how to increase financing and coverage for the sector. These include encouraging greater coordination across different levels of government, improving the governance structure, and reducing funding gaps.
Assessment of Artificial Sweeteners as Wastewater Co-Tracers in an Urban Groundwater System of Mexico (Monterrey Metropolitan Area)
Authors: Ramos Edrick , Padilla-Reyes Diego , Mora Abrahan , Barrios-Piña Hector , Kant Shashi , Mahlknecht Jürgen
Published: October 2022

Contamination from wastewater infiltration, typically from leaky sewers, poses a threat to urban groundwater resources. Artificial sweeteners (Asws), used as sucrose substitutes in many products of daily consumption, are released into groundwater systems and may be used as tracers of wastewater in urban groundwater environments, because most of these compounds are discharged directly into sewer systems. Here, for the first time, we investigated the occurrence of Asws in an urban groundwater system in Mexico. Artificial sweetener concentrations of acesulfame (ACE), aspartame (ASP), cyclamate (CYC), saccharin (SAC), and sucralose (SUC) were tested in 42 production wells in the Monterrey Metropolitan Area (MMA). The detection frequencies of quantified Asws observations were in the order ACE (57%) > SUC (54%) > SAC (7%), with SUC being the most abundant Asws, with concentrations below the quantification limit (BQL) of 2.9 µg/L, followed by ACE (BQL 0.73 µg/L) and SAC (BQL 1.4 µg/L). ASP and CYC were not detected at any sampling site. Considerable Asws ingestion amongst the MMA population is the main input source of Asws into the city’s wastewater network, percolating into the urban groundwater system due to leaky sewers. Our work shows that the application of Asws as wastewater tracers (SUC and ACE) effectively determines wastewater sources affecting urban groundwater.
Substitution of Fishmeal in a Diet for the Carnivorous Marine Fish Pagrus auratus (Bloch and Schneider) from Southeastern Australia
Authors: QUARTARARO N.
Published: October 2022

The growth of Australian snapper (Pagrus auratus)(Bloch and Schneider) fed diets based on different sources of protein was compared. Two commercial diets for other carnivorous species and two experimental diets for snapper were compared. Fishmeal was the predominant source of protein for one experimental diet (60% content), while the other contained only 10% fishmeal with the remainder of the protein sourced from soybean meal and poultry offal meal. Replacement of fishmeal gave a lower growth rate and higher (poorer) apparent food conversion ratio (FCR, weight of feed given/ live weight gain) compared to the fishmeal diet. The growth rate and FCR obtained with the soybean meal and poultry offal meal diet was similar to that of the two commercial diets tested. Fatty acid analysis of the two experimental diets indicated that concentrations of essential fatty acids exceeded those reported to reduce growth of snapper. Concentration of lysine in the experimental diet associated with reduced growth was lower than that in the diet based on fishmeal.

Isolation of Aeromonas hydrophila from Oreochromis niloticus during Fish Disease Outbreaks in the Philippines
Authors: YAMBOT A. V.
Published: October 2022

The study focused on the bacteriological examination of Nile tilapia, Oreochromis niloticus, during fish disease outbreaks in various aquaculture farms and projects in Luzon, Philippines. Farm sites and aquaculture research projects which had outbreaks were visited from January 1994 to February 1996. Fish samples were observed to have disease signs like skin lesions, ulcerations, fin rot, body discoloration, mouth sore, eye opacity, exophthalmia, dislodged eyeball, and sluggishness. High mortalities of Nile tilapia were monitored in cage culture projects notably during the rainy season and cold months. Streaking into plates of nutrient agar, trypticase soy agar and Rimler-Shotts media was done for primary isolation of bacteria. Isolates were obtained from different tissues of diseased Nile tilapia samples such as ulcerated skin and muscle, liver, kidney, spleen, gall bladder and opaque eyes. All isolates had heavy growth of yellow colonies in Rimler-Shotts media. In primary characterization tests, they were gram negative, rod-shaped, motile, oxidase positive, fermentative, 0/129 resistant and novobiocin resistant, suggesting that the colonies were aeromonads. Detailed examination using differential tests and AP! 20E showed the isolates to be Aeromonas hydrophila. All isolates were sensitive to chloramphenicol and oxolinic acid but resistant to ampicillin. Reaction to other antibiotics such as streptomycin, erythromycin and oxytetracycline varied from resistant, intermediate and sensitive. Experimental infection of the disease by immersion route was done and mortalities were monitored for 96 hrs. Results showed LC50 at 1.5 x 106 at 96 h, LC100 at 108, and no mortality at 103 and control. Moribund fish manifested the same clinical signs as the naturally infected Nile tilapia. Consistent isolation of A. hydrophila from various tissues of diseased Nile tilapia during disease outbreaks shows a recurring septicemia. Occurrence of the disease has been observed in low-volume and high-density aquaculture of Nile tilapia during the rainy season and cold months when temperatures are low. Regular disease outbreaks pose a threat to the Nile tilapia industry, necessitating steps to control the disease and minimize economic losses.

RESEARCH OF THE OPERATION OF LOW-POWER SOLID-FUEL HEAT GENERATORS UNDER THE CLIMATIC CONDITIONS OF THE NORTH
Authors: Slobodchikov E.
Published: October 2022

The growth trend of individual housing construction in the country decides the socio-economic role in solving the housing issue of the population. The development of housing construction in Yakutia is characterized by ensuring the pace of construction and various social programs in rural areas. Due to geographic and transport and logistics difficulties, connecting many settlements and microdistricts to centralized power supply sources is difficult and incurs large budget costs. On the market there are various solid fuel heat generators of low power (up to 100 kW) with an upper fuel ignition method, using coal and wood fuel. Practice shows that these heat generators and their chimney systems experience difficulties when operating at low outdoor temperatures, which is reflected in the formation of soot on heating surfaces and acid condensate in chimneys. One of the reasons is the unsatisfactory mode of fuel combustion due to the design features of the boiler furnace. To study the influence of climatic and external factors on the operation of a solid fuel heat generator, during the heating period, measurements were made of the operation parameters of the boiler furnace and its chimney system. It has been established that with a decrease in the volume of fuel as it burns out in the furnace, the combustion temperature and heat output are significantly reduced, which is associated with an increase in the excess air coefficient.

Published: October 2022

Досліджено зимову орнітофауну семи полігонів твердих побутових відходів (полігонів ТПВ) протягом 2019–2022 року у Харківській області. Визначено 37 видів птахів з 14 родин, що живляться та відпочивають на територіях полігонів в зимовий період. Серед них 38% видів знаходяться на полігонах протягом року, 13% виключно взимку та 49% рідкісні для даного періоду. Абсолютно характерними для усіх полігонів ТПВ у Харківській області в зимовий період є 14 видів. Домінантами в досліджений період визначено представників родини Воронові (Corvidae) – грак (Corvus frugilegus) та галка (Corvus monedula). Кількість представників родини воронових у зимові місяці подекуди сягала до 6 тис. особин. Серед найбільш масових видів також шпак (Sturnus vulgaris), голуб сизий (Columba livia) та мартин жовтоногий (Larus cachinnans). Проаналізовано динаміку знаходження видів на полігонах ТПВ, що дало розуміння про роль полігонів для окремих видів. Так, мартини жовтоногі (L. сachinnans) використовують полігони ТПВ виключно як кормову базу, тоді як шпаки (St. vulgaris) – як простір для перечікування найбільш холодних періодів, а голуб сизий (C. livia) як постійне місце перебування. Визначено фактори прямого та опосередкованого впливу на формування видового складу птахів, серед яких біотопічна характеристика полігону ТПВ, частота наповнення полігонів відходами, географічне положення території, близькість природних і штучних водойм та населених пунктів, погодні умови та ін. Визначено коефіцієнт подібності Жакара для усіх територій, який варіював в межах 0,50 – 0,75 значення показнику. Що свідчить про значну подібність між видовим складом птахів причетних до полігонів ТПВ, а отже значну роль даних територій у життєдіяльності птахів. Найбільша подібність серед семи полігонів у Дергачівського та Роганського пояснюється тим, що вони мають найменшу відстань один від одного і обслуговують одне місто. Полігони ТПВ визначено територіями, що відіграють значну роль для птахів регіону в зимовий період, а також були зафіксовані як простір збору для ночівель великих зграй птахів родини воронових

Current state of forest carbon budget accounting both in Russia and abroad is characterized by wide variety of

methodological approaches and models. Therefore, final estimates have discrepancies. The results of comparative analysis of methods used to assess carbon sequestration in pine-birch forest stands are presented. The composition, growth

and biological productivity of forest stands were analyzed as well as carbon stock was calculated for pine-birch forest

stands in various age groups in the Central Forest-Steppe. The dynamics of biological productivity of modal forest

stands with mixed composition is investigated. Significant differences were found in quantitative assessment of carbon

deposited by forest stands obtained with three different methodologies. Discrepancies in carbon content estimations in

forest stands with different age and composition obtained by different methods vary from 2.0 to 33.9%. The problem of

reliable assessment of carbon sequestration by forest ecosystems of the Central Forest-Steppe requires regional approaches in development of assessment methods to provide precise results and minimize uncertainty of evaluations

Published: October 2022

The AISI 316L steel is a material used to manufacture prostheses and medical instruments due to its high corrosion resistance. However, its wear resistance is low, but it can be improved by synthesizing thin films of titanium nitride (TiN) on the surface. This compound is a hard material that improves its tribological and corrosive properties, in addition to presenting good adhesion to the substrate. In this work, a Ti/TiN thin film was obtained using the Physical Vapor Deposition (PVD) technique. This coating was characterized by scanning electron microscopy, energy dispersion spectroscopy (EDS), and light microscopy; additionally, tribological tests under wet conditions and adhesion tests were conducted. The coating showed good adhesion to the substrate according to the VDI standard. In tribological tests, a low coefficient of friction vs. a polyethylene pin in a wet environment (bovine serum) was obtained. The EDS showed a high concentration of Ti and N on the substrate even after wear tests.

Conceitos bakhtinianos na compreensão do texto literário: dialogismo e plurilinguismo como princípios de construção do sentido
Authors: Fernandes Otávia Pinheiro Pedrosa , Barreto Filho Ricardo Rios
Published: October 2022

Este artigo tem como objetivo trazer ao leitor/professor dois conceitos bakhtinianos que podem contribuir na elaboração de atividades sobre a compreensão de um texto literário. Entendendo que a natureza da linguagem é social, Bakhtin revela que a construção e produção do sentido surge para sujeitos historicamente situados e envolvidos em relações discursivas. Assim, cada ato de fala é repleto de assimilações e reestruturações destas diversas vozes, ou seja, cada discurso é composto de vários discursos. Essas vozes dialogam dentro do discurso, não se tratando, apenas, de uma retomada. Esse diálogo é construído histórica e socialmente. A partir dele se dá a construção da consciência individual do falante. Só pensamos graças a um contato permanente com os pensamentos alheios, pensamentos estes expressos no enunciado. Dessa forma, a consciência individual é resultante de um diálogo interconsciências. Através de um estudo qualitativo, analisamos uma atividade, proposta pela TV5, sobre contos de Charles Perrault. Vimos que, quando o professor está atento à dialogia e ao plurilinguismo presente na interação atividade - professor – aluno, a compreensão literária pode ser mais rica e prazerosa na sala de aula.
A representação social sobre o surdo: um estudo de caso
Authors: Menezes Tayana Dias de , Monteiro de Barros Kazue Saito
Published: October 2022

A finalidade desse artigo é analisar a Representação Social (RS) sobre o surdo sob a perspectiva do próprio grupo, ou seja, procuraremos averiguar como os surdos ancoram noções como a deficiência; a normalidade; dentre outras, no processo de categorização de pares. Para tanto, revisaremos a base teórica da Teoria da Representação Social (TRS), desenvolvida por Moscovici, e os conceitos fundamentais das abordagens dos discípulos moscovicianos. Além disso, explicaremos o aparato teórico construído, sob o sustentáculo de insumos teóricos de Moscovici (1978; 2003; 2015) e Doise (2002; 2014; 2015), para dar conta da análise sobre a (re)construção da RS enquanto um processo cognitivo complexo que possui marcas sociais. As análises foram feitas por meio dos discursos de alunos e professores surdos do curso de Letras-Libras da UFPE, colhidos por meio de questionários/ entrevistas. Procuramos, dessa forma, observar a complexa relação entre o sujeito, a cognição e a sociedade. Os resultados também foram analisados com base em Vala (1986; 1997; 1999; 2002; 2004; 2010 2015) que estabelece parâmetros para novas formas de expressão de preconceito.
A gordofobia no gênero notícia em uma análise textual-discursiva da representação discursiva e da responsabilidade enunciativa
Authors: Vasconcelos Roberta Guimarães de Godoy e , Bernardino Rosângela Alves dos Santos , Queiroz Maria Eliete De
Published: October 2022

Este artigo objetiva analisar o modo como se manifesta a representação discursiva (Rd) e a (não) assunção da responsabilidade enunciativa (RE) em uma notícia sobre um episódio de gordofobia publicada na revista Claudia, em fevereiro de 2020, tendo em vista a gestão dos pontos de vista (PDV) no texto pelo locutor-enunciador primeiro (L1/E1). Para isso, assumimos uma perspectiva que articula os planos de análise do texto e do discurso, centrando o foco nas dimensões semântico-pragmática, enunciativa e sociodiscursiva, sob a ancoragem da Análise Textual dos Discursos (ADAM,2019, 2011, 2010) e da teoria do ponto de vista (RABATEL, 2016a, 2016b). Metodologicamente, o trabalho norteia-se pelas seguintes categorias: a referenciação e a modificação, para análise das Rd; as modalidades e as indicações de quadros mediadores, para análise da RE; as formações sociodiscursivas e o interdiscurso, para compreensão da relação entre as escolhas linguísticas evidenciadas na materialidade do dizer e as condições sócio-históricas de produção dos sentidos. Na análise, mostramos que a gestão das vozes pelo L1/E1 é, de um lado, prototípico do gênero notícia, nos momentos em que essa instância discursiva focaliza outros enunciadores e atribui a eles a responsabilidade pelo conteúdo dos PDV; mas, de outro lado, as escolhas lexicais (referenciais e modificadores), a organização dos signos linguísticos (verbais e imagéticos) orientam argumentativamente o texto, conduzindo o interpretante a perceber as diferentes Rd e os elos de responsabilização do L1/E1 com o PDV da vítima do episódio de gordofobia e com aqueles que se manifestaram em seu apoio e acolhimento.PALAVRAS-CHAVE: Notícia; Pontos de vista; Representação discursiva; Responsabilidade enunciativa; Gordofobia.
A contingência da coerência à luz da noção de contexto: análise de tuítes do Globo Rural
Authors: Marques Girllaynne Gleyka Bezerra dos Santos , Santana Gabriel Do Nascimento
Published: October 2022

O presente trabalho se ancora na Linguística Textual (LT), buscando refletir sobre como a noção de contexto e suas categorias de emergência e incorporação (HANKS, 2008) contribuem para elucidar os processos de construção da coerência em interações digitais. Concebemos o texto como evento (MARCUSCHI, 2008; CAVALCANTE; CUSTÓDIO FILHO, 2010), abarcando nessa noção o fenômeno do hipertexto, como manifestação textual caracterizada por especificidades que tornam ainda mais central a noção de contexto e a construção da coerência nas interações digitais (PAVEAU, 2020; ELIAS; CAVALCANTE, 2017). Compreendemos o contexto enquanto movimentos de emergência e incorporação e a construção da coerência enquanto uma construção de sentido altamente local e contingente, o que nos permite tratar a construção da coerência de forma mais sistemática. Partindo dessas categorias e do desafio do texto nativo digital para a investigação linguística, analisamos um tuíte da página oficial do programa de televisão “Globo Rural”, observando como a incorporação de uma interação a mais de um contexto pode ser estratégica para o engajamento nas interações digitais, aspecto reforçado em interações subsequentes que enfatizaram o caráter ambivalente do tuíte entre os campos político e do agronegócio. Além disso, notamos como os comentários ao tuíte indicaram uma construção de sentido variando entre sentidos estritos, sentidos estabelecidos na relevância interpretativa ou na relevância topical. Portanto, enfatiza-se que a coerência se constrói em vários níveis, que o contexto é construído na interação e, principalmente, que coerência e contexto são altamente dinâmicos em relação às interações estabelecidas pelos participantes na prática discursiva.
Gente, temos um gênio aqui: a coconstrução da violência linguístico-discursiva em uma interação no Twitter
Authors: Albuquerque Rodrigo , Sousa Ana Luiza Nogueira
Published: October 2022

A partir deste trabalho, almejamos analisar de que modo dois internautas, a partir de uma postagem do Ministério da Saúde no próprio perfil do Twitter, utilizam, em sua argumentação, estratégias de impolidez na promoção de mútua violência linguístico-discursiva. No âmbito teórico, articulamos os estudos de (im)polidez, inscritos em domínios micro/linguístico, macro/sociodiscursivo e meso/sociointeracional, e os estudos da argumentação, com foco na argumentação erística, dada a sua intrínseca relação com a violência linguístico-discursiva. No âmbito metodológico, optamos por conduzir um estudo netnográfico, inscrito em uma episteme exclusivamente qualitativa, na seleção e na análise de textos relacionados a uma interação mediada on-line no Twitter que tivesse um caráter conflituoso e que discutisse a hidroxicloroquina como estratégia de tratamento precoce no combate ao COVID-19. No âmbito analítico, salientamos que, de modo geral, a impolidez se tornou gradativamente mais intensa entre o internauta e a internauta, instaurando-se uma argumentação erística, permeada por argumentos ad hominem e ad personam, na coconstrução de metapragmáticas de violência linguístico-discursiva. Acreditamos ser salutar que perfis institucionais possam instituir políticas de moderação de tais interlocuções, incentivando diálogos construtivos e agregadores.

Published: October 2022

The paper aims to compare and choose the most suitable criteria equation for the computation of the convective heat transfer coefficient on the refrigerant side of the evaporator. The comparison is carried out by considering a given air handling unit equipped with a specific evaporator operating with refrigerant R134a. A mathematical model is given. The results obtained for criteria equations available in the work of Shah (1982), Gungor and Winterton (1987) and Kandlikar (1999) have been compared. The first criterion equation of Shah (1982) is selected because it leads to a value for the evaporator pipe length close to the one measured on the air handling unit and also it can be applied for a wider range of refrigerants used in the field of air conditioning.
