Authors: Spannenberg Ana Cristina , Souza Bianca Mara Guedes de
Published: January 2021

Considering the importance of journalism in social life and its ability to build and maintain stigmas, this article presents the results of a research that sought to verify how HIV positive people are represented in Veja’s reports. We conclude that the magazine is unable to construct the AIDS narrative in a humanized way. For this, the work considered the perspectives of Ijuim (2011) on humanized journalism, the research by Soares (2002) and Fausto Neto (1999) on the AIDS narrative, and the indications of Coimbra (2004) and Brait (1985) for the construction of characters in the journalistic text, taking into account the methodology of Content Analysis (BARDIN, 2011).

Published: January 2021

Considerando a importância do jornalismo na vida social e sua capacidade de construir e manter estigmas, o presente artigo apresenta os resultados de uma pesquisa que buscou verificar como as pessoas soropositivas são representadas nas reportagens da revista Veja. Concluímos que a revista não consegue construir de forma humanizada a narrativa sobre Aids. Para isso, o trabalho considerou as perspectivas de Ijuim (2011) sobre jornalismo humanizado, as pesquisas de Soares (2002) e Fausto Neto (1999) sobre a narrativa da Aids, e as indicações de Coimbra (2004) e Brait (1985) para a construção de personagens no texto jornalístico, levando em conta a metodologia de Análise de Conteúdo (BARDIN, 2011).
DIVERSIDADE E EQUIDADE NA GOVERNANÇA EDITORIAL DO JORNALISMO: a inclusão como credibilidade
Authors: Moreira Fernando , Carvalho Pedro Henrique Varoni de
Published: January 2021

Fazemos um paralelo estrutural entre raízes históricas e ideológicas de colonialismos, a partir das Ciências Sociais, e sua manifestação resultante nos discursos e nos modos de existência, sendo o jornalismo uma dessas formas manifestadas. A partir desse contexto, propomos um novo construto, um locus enunciativo mais inclusivo e menos verticalizado, resultando, assim, em diálogos midiáticos com a sociedade, um existir-com, evitando o monologismo estereotipado.
DO SONHO DO OURO AO ACESSO À TERRA: signos da violência em Serra Pelada e histórias de vida em Palmares II
Authors: Aragão Pinto Jax Nildo , Barbalho Marcelo , Firpo de Souza Porto Marcelo
Published: January 2021

A proposta deste artigo é mostrar que Serra Pelada (1980-1992), o maior garimpo a céu aberto do mundo, mantém estreita relação com a formação de assentamentos rurais no sudeste do Pará. Para demonstrar que a epopeia dos garimpeiros e a luta histórica dos trabalhadores por um pedaço de terra estão relacionadas há mais de três décadas, são usados dois recursos: uma fotografia feita por Sebastião Salgado em Serra Pelada, em 1986, e depoimentos de ex-garimpeiros que hoje vivem em Palmares II, assentamento criado no município de Parauapebas, em 1996. A discussão tem como base o contexto sócio-político-econômico da fase final da ditadura militar e as primeiras ações do Movimento dos Trabalhadores Rurais Sem Terra (MST) no Pará.

Published: January 2021

A comunidade de Piquiá de Baixo, localizada na Cidade de Açailândia/MA, se mantém em luta pelo seu espaço, a fim de manter seu legado e o direito à moradia. Este percurso veio de um longo processo que configurou intenso painel de enfrentamentos, iniciado com a luta pela fixação na terra, com a chegada dos latifundiários e se estendendo até o impacto ambiental causado pelas empresas mineradoras. Nesse cenário conflitivo, trazemos como objetivo examinar as formas de denúncia e resistências dos moradores, tendo como lócus privilegiado de análise as histórias de vida dos moradores. Tratar-se-á de uma pesquisa qualitativa, com dupla abordagem: a cartografia social, que valoriza as memórias coletivas e o discurso em uma rede social que repercute as histórias de vida. Constatamos que há um empoderamento e denúncia política através do ativismo digital, contrário ao discurso hegemônico

MODELO de produção de mídias alternativas como soluções democráticas para a desinformação
Authors: Moscoso Lina
Published: January 2021

Meios alternativos digitais podem ser exemplos de produção jornalística ética, na medida em que subsistem por meio do modelo de financiamento coletivo e, portanto, devem manter sua imagem perante o público. O presente artigo analisa as estratégias das mídias alternativas que as tornam possíveis saídas para a desinformação e para as notícias falsas. O desenho metodológico inclui uma análise dos discursos de entrevistas realizadas com as mídias alternativas relativamente às estratégias de verificação da informação e aos modelos de produção e distribuição; e observação dos sites e das redes sociais dos meios de comunicação. O estudo incide sobre mídias alternativas de contextos diferentes:  Brasil e Portugal, e com perfis díspares (jornalismo investigativo e mídia factual), portanto, trata-se de uma pesquisa comparativa. O artigo conclui que os meios de comunicação alternativos podem ser contrapontos à desinformação às notícias falsas, se conseguirem articular o modelo de distribuição digital com o jornalismo ético e autossustentável.

Authors: Mira de Sousa Ramilla Rízzia
Published: January 2021

Para o uso de fármacos como o antifúngico Tiabendazol (TBZ) se faz necessário o conhecimento da dose administrada, bem como a eficácia de ação do medicamento. Assim, sistemas de liberação controlada (SLC) são adaptações farmacêuticas desenvolvidas para otimizar a biodisponibilidade do fármaco pelo organismo, se comparado aos sistemas convencionais. Uma vez que são capazes de mitigar os efeitos colaterais decorrentes do uso, podem contribuir para o avanço da saúde humana. É necessário para estes sistemas uma matriz. Uma alternativa interessante é a utilização da sílica. Um composto capaz de formar materiais híbridos orgânico-inorgânicos que podem ser obtidos de fontes minerais e vegetais. No presente trabalho foram utilizadas nanoesferas de sílica funcionalizadas com 2-mercaptobenzimidazol para o carregamento e liberação controlada do fármaco tiabendazol. O material empregado apresentou uma liberação lenta, com máximo de liberação após 10 horas tanto no fluido gástrico simulado (FGS) quanto no fluido intestinal simulado (FIS).

Authors: Widiastuti Dyah , Sari Ihda Zuyina Zuyina Ratna , Kalimah Isya Fikria , Setiani Endang
Published: January 2021

Hand hygiene is one of the important factors that determine a person's health status. Hands are easily contaminated by microbes from the environment such as bacteria, viruses, and fungi through direct contact. Hand sanitizer is a type of media that can be used to clean hands from disease-causing microbes other than soap. Hand sanitizers are widely used by the community because they are considered more practical to use. This study aims to determine the anti-fungal activity of the hand sanitizer recommended by the World Health Organization (WHO) against Candida albicans. Anti-fungal activity was tested using the well diffusion method. The results showed that the higher the concentration of the hand sanitizer, the bigger the inhibition zone formed. The statistical test results obtained a significance value of p <0.05 at the variation of the concentration of hand sanitizer 50%, 75%, 100%, and treatment control. These results indicate that there is a significant difference between the hand sanitizer treatment and control of the inhibition zone formation in C. albicans. The WHO recommended hand sanitizer has medium inhibitory power against C. albicans bacteria.

‘Me inda nampak’ – Pronoun Use in Malay-English Codemixed Social Media Texts
Authors: Aziz 'Aqilah
Published: January 2021

This paper investigates the use of English the first-person singular object pronoun ‘me’ as a subject in conversation on WhatsApp and Telegram between university students in their twenties. It was found that the feature occurs more when interlocutors are code switching, especially in paired chats when ‘me’ often replaces the Malay pronoun aku or saya. This paper explores reasons for this, and how this feature has come to be used in synchronous electronically mediated conversations between young Bruneians. The findings show that using ‘me’ serves as a polite speech marker which is perceived as a softer expression than Malay aku in conversations, depending on the interlocutors.

Published: January 2021

Rosemytle leaves (Rhodomyrtus tomentosa (Ait.) Hassk) have been used by society to treat various diseases related to bacterial infections, such as dysentery and typhoid fever caused by Shigella dysenteriae and Salmonella typhi, respectively. This study aimed to evaluate the antibacterial activity of essential oils from rosemytle leaves against both bacterias. Extraction was performed with a macerating device using n-hexane, ethyl acetate, and ethanol extracts, sequentially. This study used the agar diffusion method to test the antibacterial activity applied to the essential oils with concentrations of 1000, 500, 250, 125, 62.5, and 31.25 μg/mL. The antibacterial test results showed that n-hexane and ethyl acetate extracts were active against both bacterias while ethanol extract was not. Then, isolates N1 and E1 were produced respectively from n-hexane extract and ethyl acetate extract. The MIC values of both N1 and E1 for S. dysenteriae, and S. typhi were the same, namely 125 μg/mL. Isolate N1 was an essential oil containing menthol (59.60%), caryophyllene (25.77%), and cubenol (14.63%) while isolate E1 was an essential oil containing (73.93%), pentanone (8.30%), alpha calacorene (7.58%), and calacorene (3.78%). Rosemytle leaves have the potential to be developed as a drug to treat dysentery and typhoid fever.

Conductivity as a New Monitoring Technique for Zinc Metal Corrosion and Corrosion Processes
Authors: Alkhawaldeh Ahmad Khalaf
Published: January 2021

The electrical conductivity method was successfully applied to monitor the corrosion and corrosion inhibition processes of zinc metal. Measurements of electrical conductivity at 20.0 oC of three different corrosive solutions (NaCl, HCl and NaOH) were performed with two different concentrations (0.10 and 1.00 M) containing zinc sheets in the absence and presence of four different concentrations of sodium lignosulfonate (1.0, 5.0, 10.0, and 20.0 mM). The analysis of curves that illustrates the changes in electrical conductivity of these solutions provides qualitative information about the strength of corrosion as well as the extent of corrosion inhibition behavior. The results obtained from electrical conductivity measurements revealed that sodium lignosulfonate was an effective corrosion inhibitor in acidic medium (for both 0.10 and 1.00 M HCl) in which it converted into lignosulfonic acid, but was less effective in salt and alkaline media.

Evaluation of High-Resolution Satellite-Derived Solar Radiation Data for PV Performance Simulation in East Africa
Authors: Palmer Diane , Blanchard Richard
Published: January 2021

Access to reliable, clean, modern cooking enhances life chances. One option is photovoltaic cooking systems. Accurate solar data is needed to ascertain to what extent these can satisfy the needs of local people. This paper investigates how to choose the most accurate satellite derived solar irradiance database for use in Africa. This is necessary because there is a general shortage of ground measurements for Africa. The solar data is needed to model the output of solar cooking systems, for instance, a solar panel, battery and electric pressure cooker. Four easily accessible satellite databases are validated against ground measurements using a range of statistical tests. Results demonstrate the impact of the mathematical measure used and the phenomenon of balancing errors. Fitting of the satellite model to appropriate climate zone and/or nearby measurements improves accuracy, as does higher spatial and temporal resolution of input parameters. That said, all the four databases reviewed were found to be suitable for simulating PV yield in East Africa.

Published: January 2021

The paper describes the research findings on dynamic and mechanical properties of composite elastomers with high permeability magnetic filling agent capable of rapidly and reversibly changing its properties when exposed to an external magnetic field, which makes it a perspective material for application in a wide range of engineering areas. The research has analyzed the trends in the strength properties of the materials obtained through the use of filling agents of different fineness, content, and structural organization in the final polymer, under different conditions. This allowed to obtain the correlations between the influence of the filler's relative fineness on the dynamic and mechanical properties of composite polymers, and to estimate the trends in the parameters describing the material strength under the complex magnetic and thermal influence. The results obtained by the authors allowed to ground the composition and structural organization of the final material with the best set of dynamic and mechanical properties.
Utilisation of Post-extraction Fir Wood Greenery Residues by the Bioconversion Method with the Production of Feed Additives
Authors: Mamaeva Olga O. , Isaeva Elena. V.
Published: January 2021

The effectiveness of forest resources depends on the comprehensiveness and rationality of their consumption and processing into finished products. This article discusses a problem of utilising solid fir wood greenery residues generated during the industrial production of essential oils. Bioconversion is considered to be the most promising utilization method. The objective of this research was to study the chemical composition of bioconversion products of fir wood greenery-based substrates. The РР-3.2 strain of Pleurotus pulmonarius (Fr.) Quél was used as a biodestructor.
In the process of bioconversion, the contents of polysaccharides and lignin substances is reduced to 38 and 28 % respectively. Up to 20 % of protein accumulates in bioconversion products of fir wood greenery. The amount of nucleic acids is not more than 1.5 g per 1 kg, the contents of heavy metals, such as mercury, cadmium, arsenic, lead, do not exceed maximum permissible concentration standards. The substrate weight loss reaches 15 %. When fallen leaves and post-extraction poplar bud residues are added to the substrate, the substrate-destroying activity of fungi rises, as well as the protein content increases by 3 %. The digestibility of products as a result of bioconversion increases 1.6–2.8 times depending on the substrate composition.
The obtained data enable to recommend post-fermented substrates based on fir wood greenery and balsam poplar biomass for use as a protein feed additive.

Background:

Knee arthroscopy may be performed prior to total knee arthroplasty (TKA) in patients with symptomatic degenerative knee changes that do not yet warrant TKA. The purpose of this study was to determine whether the time interval between knee arthroscopy and subsequent primary TKA is associated with increased rates of revision and certain complications following TKA.

Methods:

Data from 2006 to 2017 were collected from a national insurance database. Patients who underwent knee arthroscopy within 1 year prior to primary TKA were identified and stratified into the following cohorts based on stratum-specific likelihood ratio (SSLR) analysis: 0 to 15, 16 to 35, 36 to 43, and 44 to 52 weeks from the time of knee arthroscopy to TKA. Univariate and multivariable analyses were conducted to determine the association between these specific time intervals and rates of revision surgery, periprosthetic joint infection (PJI), aseptic loosening, and manipulation under anesthesia.

Results:

In total, 130,128 patients were included in this study; 6,105 (4.7%) of those patients underwent knee arthroscopy within 1 year prior to TKA and 124,023 (95.3%) underwent TKA without any prior knee surgery, including arthroscopy (the control group). Relative to the control group, the likelihood of undergoing revision surgery was significantly greater in patients who underwent knee arthroscopy ≤15 weeks (odds ratio [OR]: 1.79; 95% confidence interval [CI]: 1.43 to 2.22; p < 0.001) or 16 to 35 weeks (OR: 1.20; 95% CI: 1.01 to 1.42; p = 0.035) prior to TKA. Patients were at significantly increased risk for PJI if knee arthroscopy was done ≤35 weeks prior to TKA, and all 4 time groups that underwent knee arthroscopy within 1 year before TKA were at increased risk for manipulation under anesthesia.

Conclusions:

We found a time-dependent relationship between the timing of knee arthroscopy and complications following TKA, with the prevalence of revision surgery and PJI increasing as knee arthroscopy was performed closer to the time of TKA. This study suggests that an interval of at least 36 weeks should be maintained between the 2 procedures to minimize risks of PJI and revision surgery.
