Authors: Tuwaijri Majdah , Souad Sayed
Published: September 2023

Inonotus obliquus (Chaga mushroom) is a herbal and edible mushroom widely distributed in different regions, especially temperate regions. Chaga parasites on the trunk of angiosperms and grows, forming an irregular black mass. The medical importance of Chaga has been reported from ancient cultures to data due to its activity against a wide range of diseases. In the present study, the ethyl acetate extract of the Chaga mushroom has been tested against two bacterial pathogens, Staphylococcus aureus ATCC25923 and Salmonella typhimurium ATCC14028. The antimicrobial activity of the extract showed high activity with inhibition zone diameters of 25 mm for S.aureus and 28 mm for S.typhimurium and minimum inhibitory concentration (MICs) of 3.125 µg/ml for both bacterial pathogens. GC-MS analysis of the extract revealed several compounds with seven major compounds; they are 3-pentanone, propyl butyrate, Ethyl propionate, Trimethylsilymethanol, Neopentyl glycol, n-butyl acetate, and 1-butanol-3-methyl acetate. The antibacterial mode of action of Chaga extract was also elucidated by studying the effect of the extract on cell membrane permeability and recoded high effect on bacterial cell membrane permeability, which was confirmed by transmission electron microscope (TEM) images that revealed leakage of bacterial cell content outside the cells and death.

Published: September 2023

Objective: The assessment of premorbid intelligence and adjustment/functioning in schizophrenia is quite important for clinical evaluation. Several methods can be used to estimate premorbid functioning. However, these methods may be affected by retrospective bias, verbal skills, and the disorder itself. This study aimed to investigate whether the Raven’s Standard Progressive Matrices Test (RSPM) performance is related to premorbid intelligence/functioning, or adjustment in schizophrenia.
Methods: Schizophrenia patients (n=31) and healthy controls (n=30) were included in the study. The Premorbid Adjustment Scale (PAS), the Positive and Negative Syndrome Scale (PANSS), and the Personal and Social Performance Scale (PSPS) were applied to patients with schizophrenia, while the WAIS-R and the RSPM were applied to all participants.
Results: No statistically significant differences were observed between the groups in terms of age, sex, and total years of education (p=0.86, p=0.06 and p=0.10, respectively). Healthy controls performed significantly better than the patient group in terms of intellectual abilities as measured by the RSPM and the WAIS-R. The RSPM performance was correlated with all WAIS-R scores, total years of education, and the academic subscale of the PAS, while it was not correlated with the PAS-developmental scores or the PSPS and PANSS scores of patients with schizophrenia.
Conclusion: The results of the study support the validity of the RSPM which is an easily applied tool that is not affected by verbal skills as a good measure of premorbid intelligence, and adjustment/ functionality in patients with schizophrenia.

Published: September 2023

Advanced Polymerization System (APS) technology in a commercial composite resin enables reduction of the concentration of camphorquinone without altering composite physicochemical properties. Aim: The aim of this study was to evaluate the degree of conversion and mechanical properties of a commercial composite with an advanced polymerization system (APS) and compare it to other composites that do not use this system. Materials and Method: Five groups were analyzed. Group 1 (VT: Vittra APS - FGM); G2 (AU: Aura – SDI); G3 (ES: Quick Sigma Stelite – TOKOYAMA); G4 (FZ: Filtek Z350 XT – 3M ESPE); G5 (OP: Opallis -FGM). Degree of conversion (DC, n=3) was analyzed immediately and after 24h by analysis with FTIR spectroscopy. For Knoop hardness (KHN, n=3), 5 indentations were made at the top and bottom of specimens 2 mm thick. Flexural strength (FS, n=10) was determined by the three-point method in a universal testing machine. Polymerization stress (PS) was determined by light-curing the material (1.0 mm high) between polymethylmethacrylate rods in a universal testing machine. Light curing was performed with a Valo Cordless LED (1,000 mW/cm2 x 20 s: 20J). The results were analyzed using ANOVA and complemented by Tukey’s test (α=0.05). Results: The highest DC values (immediate and 24h after) were observed for VT and OP resins, followed by FZ, AU and ES. FZ (top and bottom) had the highest KHN values, similar to VT top. AU, ES, OP and VT had statistically different KHN between their top and bottom surfaces. The highest RF values were observed for FZ, followed by OP/VT, ES and AU. The highest TP values were observed for FZ, OP and VT.

Published: September 2023

The oral cavity constitutes a unique ecosystem with highly variable ecological niches that harbor a great variety of microorganisms, including yeasts. Molecular methods are currently considered the gold standard for identifying species, although they involve limitations associated with the disruption of yeast cell walls to release the genomic DNA (gDNA) for amplification. Aim: The aim of this study was to compare the performance of different methods for extracting gDNA from Candida albicans and Candida dubliniensis, subsequently amplifying DNA by PCR. Materials and Method: Fifty-two isolates (16 C. albicans and 36 C. dubliniensis) were obtained from subgingival biofilm of HIV+ patients with clinical signs of periodontal disease. The study evaluated 6 gDNA extraction methods and two PCR amplification methods. Furthermore, the presence of alleles of HWP1 gene was determined in C. albicans. Results: Comparisons of six methods show statistically significant differences (p<0.001) except for C. albicans in two of them. For C. dubliniensis, statistical differences were observed in all comparisons. Commercial methods were more efficient for concentrating gDNA than in-house methods, and both PCRs were effective. Ten heterozygous C. albicans isolates for this allele were positive for the HWP1-1 / HWP1-2 allele, one was homozygous for Wild Type HWP1-1 allele, and 5 were homozygous for novel/rare HWP1-2 allele. Conclusions: This study aims to provide simple, inexpensive strategies for phenotypic identification and molecular confirmation of Candida albicans and Candida dubliniensis for non-reference laboratories with low complexity and/or low budgets.
Exploring New (Digital) Publishing Practices with *Le Pressoir*
Authors: Fauchié Antoine , Delannay Roch , Sinatra Michael , Vitali-Rosati Marcello
Published: September 2023

As is well known, scientific publishing is a complex activity, and many constraints must be taken into account in order to address a range of issues, be they the structuration of the text, the inclusion of a critical apparatus, the sharing of texts during the revision and editing phases, and the dissemination of the final version via multiple platforms. Existing publishing chains allow for the management of texts, their production, editing and publication; they are systems that take these parameters into account by default. However, they remain dependent on specific software that is generally not well adapted to scientific publishing, or on technical infrastructures that are difficult to maintain and to use by SSH researchers, or that do not allow for experimentation and necessary rethinking on new editorial and epistemological models. What if, by modifying the publishing chains from more singular technical approaches, it is possible to consider new publishing practices? It is about rethinking the way books are edited and published through the editing of books in a university publisher series ("Parcours numériques" at the Presse de l’Université de Montréal). Several principles are adopted to reconfigure the publishing chain: multimodal publishing, modular factory, minimal computing and progressive enhancement. Furthermore, it is about what was adapted for a new publishing experiment (Les Ateliers de [sens public]) along the way.
TRULY ENGAGING AUDIENCES
Authors:   , Gajardo Leon Constanza Soledad
Published: September 2023

This dissertation studies how journalism can meet audiences’ needs as citizens, from an audience perspective. From a traditional normative perspective, it is understood that if people do not consume news, democracy loses an informed basis for an engaged citizenry (Delli Carpini and Keeter, 1996; Siebert, Peterson, & Schramm, 1956). Consequently, the main democratic function of journalism is to inform citizens so that they can deliberate about the issues that matter and make sound decisions (Christians, et al., 2010; Schudson 2008; McNair, 2009). However, at the start of this dissertation, Chile presented strong contrasting cases of increased news consumption compared with the low level of civic engagement. This apparent contradiction between theory and practice prompted me to enquire more closely into the seemingly automatic relationship between journalism and democracy: how—in both theory and practice—does journalism’s democratic role of informing the citizenry relate to civic engagement? How does the audience experience journalism as truly engaging, and how do journalists feel they truly engage with their audiences?
The results of this dissertation indicate that meeting the audience’s needs as citizens encompasses both the provision of information—a selection of topics, sources, and angles—as well as the communication of that information. This means that journalism’s democratic role might not only focus on the production and distribution of news stories, but also implies carrying out non-content-related but rather audience-related communication practices (cf. Dewey). With the above, this dissertation’s bottom-up standpoint led to rendering Dewey's postulates on the relationship between audiences, journalism, and democracy into concrete and empirical terms, not in opposition but rather in combination with Lippmann’s predominant informational view. Consequently, when studying the democratic framework of journalism from the perspective of the audience, the figure of the triangle may no longer seem adequate for schematising the relationship between citizens, journalism, and democracy. Instead, the findings of this study account for the emergence of the figure of a spiral; a dynamic of informational and communicational feedback between practitioners and their audience.

Published: September 2023

A moagem é um estágio de fragmentação do processamento mineral fundamental para garantir que etapas subsequentes de concentração sejam eficientes, visto que proporciona a liberação dos minerais de interesse econômico, tornando-os aptos a concentração. Neste sentido, este trabalho tem como objetivo verificar o impacto de alterações implementadas no circuito de moagem com o intuito de otimizar sua eficiência. Uma variedade de abordagens foi explorada neste trabalho, incluindo o uso de modelos matemáticos e simulações que permitiram encontrar a combinação ideal de variáveis operacionais, como a carga de esferas (corpos moedores) e o grau de enchimento do moinho, além da granulometria ideal e recuperação das etapas subsequentes de flotação. Portanto, foi possível compatibilizar as vazões de sólidos e as granulometrias do material nas alimentações das etapas de flotação através de simulação e comprovação com testes empíricos. Como resultado, foi possível identificar uma elevação do grau de enchimento do moinho de bolas a 35% após implementação do anel de retenção e maior distribuição dos dados na porcentagem passante em 325 mesh (ou 45 μm), comprovando aumento na relação de redução no circuito de moagem, de forma a entregar uma alimentação mais fina (< 53 μm) na etapa de flotação, o que proporcionou ganhos de recuperação relativa da flotação de nióbio de até 7,3%.

People Identification based on Geometric Face Features for Cloud Services
Authors: Hachim Ethar Abdul Wahhab
Published: September 2023

Recently, the services provided by cloud computing play an important role in many areas of life. The security component represents the major challenge that hinders the adoption of cloud services in banking, healthcare and other transactions. In this paper, secure identification approach is proposed to use cloud services by recognizing authorized persons based on facial features. In the proposed approach, the face image is sent to the cloud side without any processing. When it is received in the cloud side, the image is processed and the geometric features are extracted using moment features extractor. The features of the face are used during the matching phase by using two different classifiers to make the final decision to grant authorization to access cloud services. The experimental results showed the efficiency and accuracy of the proposed approach. The performance is test using many facial images with online applications. Where an overall accuracy level of approximately 96% was obtained.

Published: September 2023

A predominância nas discussões da Geografia sobre o Espaço como uma produção social, acunhada por Lefevbre que defende a ideia de espaço produzido, este parte e fruto das relações humanas dialetizadas, de acordo as peculiaridades de cada contexto histórico, econômica, social, cultural e ambiental. Nesta dinâmica podemos associar a figura do camponês detentor dos seus meios de produção, que ao longo do tempo sofreu a expropriação do seu trabalho nos diferentes modos de produção, sendo intensificada sobre as regras do capitalismo, se inserindo nesse processo através da luta e resistência para garantir sua reprodução espacial. Segundo Marx na Assim chamada acumulação primitiva esse grupo social sofreu as ações mais brutais e violentas da humanidade, no qual os camponeses foram expropriados de suas condições de reprodução e submetidos abruptamente ao novo cenário econômico que se desenhava  o capitalismo industrial, onde emergia um novo mundo defendido pela Burguesia e do outro lado o Proletariado que vivia o mundo da fantasia, das oportunidades e liberdades para celebrar contrato entre iguais juridicamente que essencialmente se desenvolvia a partir da exploração do trabalho não pago, que na verdade escancarava um abismo da desigualdade social. Atualmente vislumbramos em diferentes lugares do mundo a superposição do capital sobre a agricultura e aqui especificamente ao camponês, quando não se apropria, explora através das relações capitalista, o mesmo se metamorfosea por meio de relações não capitalistas essencialmente. Toda uma estrutura legitimada ou propagada pelo próprio Estado que associado a força do capital dificultando a reprodução do sujeito enquanto camponês.

Published: September 2023

Este artigo apresenta a aplicação de uma técnica de controle avançada, denominada controle preditivo baseado em modelo, embarcado num controlador lógico programável (Programmable Logic Controller - PLC) como plataforma de desenvolvimento de um algoritmo de controle baseado em modelo simplificado. Visando a diminuição do custo computacional e viabilidade de aplicação em PLC é utilizada uma abordagem abreviada do controlador preditivo generalizado (Generalized Predictive Control - GPC). O formalismo matemático, projeto e simulação de processos simples e complexos, com modelo estimado com função de transferência de ordem reduzida, são mostrados. O objetivo desejado é assegurar estabilidade, robustez, seguimento de referência e rejeição de perturbação mesmo na presença de erro de modelagem. A avaliação é conduzida em três ensaios: numérico, experimental com um processo em escala de laboratório de nível e hardware in-the-loop utilizando o controlador preditivo embarcado no PLC na regulação da velocidade de turbinas hidráulicas. As respostas dos sistemas avaliados são comparadas com índices de robustez. Ambos controladores preditivos têm desempenho semelhantes, são capazes de garantir offset nulo e manter a estabilidade do sistema de malha fechada. A concretização do controle preditivo em PLC é de interesse e almeja o uso na indústria. Este artigo contribui pela averiguação, efetivação e benefício do controle preditivo em campo, mostrando a eficiência em diferentes sistemas com a comprovação das propriedades de estabilidade e robustez.

Published: September 2023

As dificuldades enfrentadas por professores e estudantes no trabalho com objetos matemáticos, podem ser interpretadas do ponto de vista do processo tranpositivo, situando-se num sistema antropológico em que os fenômenos que interessam são de cunho didático. Nesse artigo, no âmbito dessa problemática, objetivamos analisar a priori as condições de existência e restrições institucionais do saber Função quadrática no desenvolvimento de um Percurso de Estudo e Pesquisa – PEP, que permite a exploração de uma situação que pode levar futuros professores a compreensão da noção de parábola à desse tipo função. Trata-se de um estudo de abordagem qualitativa, configurando-se nesse ensaio teórico, que traz elementos da Didática Codisciplinar teorizada por Yves Chevallard. A referida análise a priori das questões que compuseram o PEP, nos permite concluir que existe uma condição de existência epistemológica para que sigamos um caminho de estudar, para compreender, a noção de função quadrática a partir da ideia de lugar geométrico, particularmente a parábola, e que restrições podem ser compreendidas como dificuldades, e estas estão em função das escolhas didáticas para difusão do saber em jogo sendo, portanto, provisórias.

Os óleos essenciais (OE) são produtos naturais utilizados há muitos anos e a Aloysia gratissima (Gillies & Hook) Tronc é uma espécie de planta aromática amplamente distribuída na América do Sul com grande potencial para extração de OE. Um aspecto químico interessante do OE da A. gratissima é a diversidade de compostos encontrados a depender da parte da planta utilizada bem como da época do ano e condições abióticas do local de coleta. Com base nisso, o objetivo deste trabalho foi identificar diferenças na composição química e rendimento do OE a partir de diferentes estruturas vegetativas da A. gratissima coletadas no verão em locais com solos distintos. Foram coletadas partes aéreas da A. gratissima em dois locais com solos distintos: solo raso (SR) e solo profundo (SP) no município de Santana do Livramento – RS. Foram coletadas 12 amostras, em cada local, dos seguintes materiais vegetativos: flor; folha e flor – galho – folha entre dezembro/2021 e fevereiro/2022, totalizando 24 amostras. Os OE foram obtidos por meio do processo de hidrodestilação e as amostras foram submetidas à análise de cromatografia gasosa acoplada à espectrometria de massa. As amostras de OE coletadas no SR apresentaram maior rendimento e foram estatisticamente superiores (0,75%) do que aquelas coletadas no SP (0,60%). Em relação as partes das plantas, as amostras das flores apresentaram maior rendimento estatisticamente. A partir da caracterização química foram identificados 54 compostos presentes nas amostras, sendo que os principais compostos identificados em todas elas foram o β-Caryophyllene, Spathulenol e Germacrene D.

Published: September 2023

The Amazon, rich in biodiversity and natural resources, seeks renewable energy sources to minimize environmental impacts and reduce dependence on non-renewable sources. Hydrokinetic turbines emerge as a promising alternative by making it possible to convert the kinetic energy of river currents into electricity, without the need for dams. This study focuses on exploring the sustainable potential of hydrokinetic turbines in the Amazon region. For this, a prototype hydroelectric power plant that uses a hydrokinetic turbine was developed, and the feasibility of this technology as a renewable energy source was examined. The research included 3D modeling and propeller printing for the prototype, using materials such as carbon steel and 3D printing. The electrical components were dimensioned according to current technical standards, including cables, circuit breakers, batteries and converters. The methodology included tests on the real environment of a river in the Amazon region, evaluating the power generation capacity and the adaptability of the system to local conditions. The results demonstrated that the prototype is capable of producing electrical energy efficiently, taking advantage of the strength of river currents. The flexibility of the blades allowed adjustments according to the geometry of the watercourse, increasing the versatility of the system. In addition, the modular approach of turbines has shown promise for scalability and installation in different scenarios. This study contributes to the understanding of the potential of hydrokinetic turbines in the Amazon region, offering a renewable solution for electricity generation. The combination of technologies such as 3D printing, structural and electrical modeling has resulted in a prototype adaptable to local conditions, with the potential to provide clean energy to riverine communities, reducing dependence on non-renewable sources and promoting the sustainable development of the region.

Identity and Preservation of Traditional Culture in the Context of Urbanization in China
Authors: Hu Yiyan
Published: September 2023

China’s rapid urbanization and societal advancement have resulted in the gradual neglect of traditional culture, despite the nation’s profound sense of pride in its economic, political, and scientific achievements. This paper explores the historical roots of these evolving attitudes by tracing them back to past migrations and the impact of minority rule during the Yuan and Qing dynasties. Drawing inspiration from Japan’s gradual transition and France’s experiences with urban renewal, this paper underscores the pivotal role of government policies and the imperative for public engagement in preserving traditional culture. Furthermore, the paper introduces a fresh perspective on preserving traditional architecture within the context of urbanization. It highlights the potential of 5G technology to rekindle interest in traditional culture while alleviating urban pressures. This underscores the importance of adapting traditional architecture to harmonize with urban environments and utilizing technology to ignite enthusiasm for traditional culture.

Authors: Garrido Gabino , Ortiz Macarena , Pozo Patricia
Published: September 2023

Context: Lampaya medicinalis F. Phil. (Verbenaceae) is a plant that grows in northern of Chile and it is used in ethnomedicine to treat bone pain, as an analgesic, in kidney ailments, disorders of the prostate, liver disease and dyspepsia, although there are few scientific studies about it. Aims: To determine the antioxidant activity of different extracts from leaves of L. medicinalis. Methods: Extractive methods were performed in water and methanol maceration, decoction and infusion from leaves of L. medicinalis. Phenols and flavonoids were measured and evaluated the total antioxidant capacity in vitro by discoloration radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) and inhibition of the enzyme xanthine oxidase (XO). Results: The L. medicinalis extract, obtained by maceration in methanol (LM-M), showed higher concentrations of phenols (5807.9 ± 340.0 mg of gallic acid equivalents/100 g dry sample), while the decoction (LM-Dx) showed higher concentration flavonoids (136.0 ± 5.5 mg of quercetin equivalents/100 g dry sample) with statistically significant differences (p <0.05) relative to the other extracts. Moreover, the best results for the DPPH method were to the extracts LM-M and LM-Dx (IC50 = 24.9 ± 3.6 and 24.1 ± 2.7 μg/mL, respectively), without significant differences between them (p> 0,05). However, extracts had no activity on XO. Conclusions: Polar extracts from leaves of L. medicinalis show antioxidant activity due to the presence of flavonoids and phenols that could justify the ethnomedical use of the plant in pathologies transiting by a component of oxidative stress.

Published: September 2023

Context: Duroia macrophylla (Rubiaceae) is endemic from the Amazon Rainforest. Aims: To perform phytochemical profile of Duroia macrophylla extracts and to evaluate them as antioxidant, insecticidal and cytotoxic. Methods: Dichloromethane and methanol extracts of leaves and branches (collected three times) were subjected to phytochemical screening by comparative thin layer chromatography and NMR analyses. The extracts were assayed to antioxidant (DPPH and Fe-phenanthroline, at 10 μg/mL), insecticidal on Sitophilus zeamais (by ingestion of stored grains and contact, both at 10 mg/mL) and toxic activities on Artemia salina (1000 μg/mL). Results: There were found evidences of terpenes, phenolic substances (phenols and flavonoids) and alkaloids, with differences between the vegetal part, collection period and solvent used. Antioxidant evaluations showed three of twelve were active and two were considered moderately active, with a relationship dependently of concentration. All methanol extracts showed the presence of phenolic substances (phenols and flavonoids) but one showed only phenols. For insecticidal activity, there were three most active extracts, two of which showed only presence of terpenes and the other, besides terpenes, phenolic substances (phenols and flavonoids). For Artemia salina toxicity assay, the five most active were all from the 2nd and 3rd collections. Conclusions: The active extracts of D. macrophylla in each test were different. Three methanol extracts showed antioxidant activity; three extracts showed insecticidal activity and the presence of terpenic substances and five extracts presented cytotoxic activity, but it was not possible to correlate it with any specific secondary metabolite.

Published: September 2023

Context: There are reports in the literature of species belonging to the genus Tabebuia with pharmacological potential as anti-inflammatory: Tabebuia avellanedae, Tabebuia chrysanta, Tabebuia rosea, Tabebuia ochracea, among others; however, about of the species Tabebuia hypoleuca no studies demonstrating this activity so far. Aims: To determine the anti-inflammatory activity in the acute phase of the methanolic extracts of T. hypoleuca. Methods: Leaves and stems of T. hypoleuca were collected. The anti-inflammatory activity was assessed using the carrageenin-induced paw edema models and the croton oil induced auricular edema in mice. The qualitative identification of secondary metabolites present in the methanolic extracts was performed by a preliminary phytochemical screening. Results: The anti-inflammatory activity assessments showed that methanol extract of the leaves do not have anti-inflammatory activity at doses tested, while the methanol extract of the stems at the dose of 500 mg/kg showed a significant anti-inflammatory activity in the model of carrageenan-induced paw edema. In the model of croton oil induced auricular edema the methanol extract of the stems administered orally and intraperitoneally showed a significant anti-inflammatory activity at all doses tested. The anti-inflammatory activity found could be due to the presence of metabolites such as tannins, phenols and alkaloids. Conclusions: These studies demonstrate the anti-inflammatory activity of the methanol extract of the stems of Tabebuia hypoleuca, and constitute the first report about this species as anti-inflammatory.
