Published: November 2022

Background: Members of Micobacterium. abscessus complex comprises three subspecies (M. abscessus subsp. Abscessus, M. abscessus subsp. Bolletii, and M. abscessus subsp. Massiliense) and are a rapid-growing nontuberculous mycobacteria present in different aquatic habitats and soil. It often causes a wide spectrum of infections involving pulmonary infections, surgical wound infections, and infections related to mesotherapy, catheters, hemodialysis devices, endocarditis, and disseminated infections in immunocompromised individuals. Methods: In this article we comment on the most relevant aspects of nine patients with skin lesions caused by M. abscessus subsp. massiliense infection. Clinical characteristics, histopathology, and molecular identification were performed. Results: The patients in the clinical cases presented a history of trauma, tattoos, and physical therapy techniques. The most common treatments were minocycline and clindamycin, doxycycline, ceftriaxone, cephalexin, moxifloxacin, rifampicin, and trimethoprim-sulfamethoxazole. The evolution of the treated patients was acceptable, except for one patient, who showed a partial improvement. M. massiliense were identified in all clinical cases using a species-specific PCR. Conclusion: Our series consisted of nine cases of skin biopsies recorded in different years; for this reason, we do not have all the data necessary for a complete description, in particular in four cases, causing limitations in the manuscript, especially in the therapy used and the evolution of patients due to lack of follow-up.

An Experimental and Numerical Study of the Impact of Ambient Light of SiPMs in VLC Receivers
Authors: Matthews William , Collins Steve
Published: November 2022

Silicon photomultiplier’s relatively large area and ability to detect single photons makes them attractive as receivers for visible light communications. However, their non-linear response has a negative impact on the receiver performance, including making them particularly sensitive to ambient light. Experiments and Monte Carlo simulations have been used to study this non-linearity. The resulting detailed understanding of the origins of the non-linear response leads to concerns over the accuracy of some previous simulations of SiPMs. In addition, it leads to simple methods to determine the maximum rate at which an SiPM can count photons and of determining the impact of a SiPMs non-linearity on its performance of a receiver. Finally, a method of determining which filters should be used to protect an SiPM from ambient light is proposed.

Published: November 2022

We investigated taxonomic and endemic richness, patterns of spatial distribution, cenotic and spatial diversification, and chorological and life form spectra of montane coniferous forests in the central part of the Balkan Peninsula. We collected information on 1435 taxa (1351 at the level of species and 84 subspecies) with 65,289 species-occurrence data, published in 1930 original plots with a total area of about 215 ha in the analysis. All statistical analyses (univariate and multivariate) were performed on binary matrices prepared for different levels of analysis. Our main results showed that the montane coniferous forests of the central Balkan Peninsula represent very species-rich vegetation. At the same time, the high proportion of endemics indicated that the montane coniferous forests of the central Balkan Peninsula differ significantly from Central European and boreal forests of a similar type. Furthermore, we found that there were regional differences in the species composition of the coniferous forests of the Balkan Peninsula, and that the primary centers of floristic richness are located in the area of the central and continental Dinarides. This latter finding suggested that the true centers of the richness of European coniferous forests are located south of the Limestone Alps—Western Dinarides—Carpathian Foothills line in Romania, which used to be considered the center of the richness of the coniferous forests in Europe.

Long-term application of soil organic amendments (SOA) can improve the formation of soil organic carbon (SOC) pool as well as soil fertility and health of paddy lands. However, the effects of SOA may vary with the input amount and its characteristics. In this work, a descriptive field research was conducted during one cropping season to investigate the responses of various SOC fractions to different long-term fertilization practices in rice fields and their relationships with soil biogeochemical properties and the emission of greenhouse gases (GHG). The field sites included two conventional paddies applied with chemical fertilizer (CF) or CF + rice straw (RS) and six organic agriculture paddies applied with oilseed cake manure (OCM) + wheat straw (WS), cow manure (CM) + WS, or CM + RS. The two paddy soils treated with CM + RS had significantly higher concentrations of recalcitrant to labile C forms, such as loss-on-ignition C (LOIC; 56–73 g kg−1), Walkley–Black C (WBC; 20–25 g kg−1), permanganate oxidizable C (POXC; 835–853 mg kg−1), and microbial biomass carbon (MBC; 133–141 mg kg−1), than soils treated with other SOA. Likewise, long-term application of CM + RS seemed to be the best for regulating soil fertility parameters, such as ammonium (11–141 mg kg−1); phosphate (61–106 mg kg−1); and soluble Ca, K, and Mg (7–10, 0.5–1.2, and 1.9–3.8 mg kg−1, respectively), although the results varied with the location and soil properties of rice fields. Additionally, the two paddy sites had the largest cumulative methane emission (754–762 kg ha−1), seemingly attributed to increased microbial biomass and labile C fractions. The significant correlations of most SOC fractions with soil microbial biomass, trophic factors, and methane emissions were confirmed with multivariate data analysis. It was also possible to infer that long-term SOA application, especially with CM + RS, enhanced interaction in belowground paddy fields, contributing to soil fertility and rice production sustainability. Based on our findings, we suggest the need for analysis of various types of SOC fractions to efficiently manage soil fertility and quality of paddy fields, C sequestration, and GHG emissions.

Published: November 2022

The fruit skin types of pear (Pyrus spp.) are divided into russet, smooth, and intermediate. One of the important traits in pear breeding programs is russet on pear fruit skin because it affects the commercial value. In the present study, a high-density genetic linkage map of ‘Whangkeumbae’ (smooth) × ‘Minibae’ (russet) was constructed. In addition, quantitative trait loci (QTL) analysis was performed to identify russet related QTL and develop a cleaved amplified polymorphism sequence (CAPS) marker. Together with SNPs derived from Axiom Pear 70K Genotyping Array and genotyping-by-sequencing derived SNPs and SSRs generated in previous study, an integrated genetic linkage map of ‘Whangkeumbae’ × ‘Minibae’ was constructed. A total of 1263 markers were anchored in 17 linkage groups (LGs) with a total genetic distance of 1894.02 cM and an average marker density of 1.48 cM. The chromosome coverage of ‘Whangkeumbae’ × ‘Minibae’ map was improved because the SNPs derived from Axiom Pear 70K Genotyping Array were anchored. QTL analysis was performed using previous russet phenotype data evaluated with russet coverage and Hunter a. As a result of QTL analysis, russet coverage- and Hunter a-related QTLs were identified in LG8 of the ‘Whangkeumbae’ × ‘Minibae’ map, and SNPs located in the QTL region were heterozygous in the ‘Minibae’. Although the russet coverage- and Hunter a-related QTLs were commonly detected in LG8, the logarithm of odds values of SNPs in the QTL region were higher in QTL related to russet coverage than to Hunter a. The CAPS marker (CBp08ca01) was developed using an array SNP located in the russet coverage related QTL, and the genotype of CBp08ca01 showed a 1:1 ratio in ‘Whangkeumbae’ × ‘Minibae’ (χ2 = 0.65, p > 0.05). ‘Whangkeumbae’ and ‘Minibae’ were thought to have rr and Rr genotypes, respectively, and the genetic factors controlling the russet formation might be located in chromosome 8. The CBp08ca01 was able to select F1 individuals with less than 30% russet coverage. Thus, it will be a useful tool for marker-assisted selection in pears.
Plant Growth Stimulators Improve Two Wheat Cultivars Salt-Tolerance: Insights into Their Physiological and Nutritional Responses
Authors: Talaat Neveen B. , Hanafy Alaa M. A.
Published: November 2022

Spermine (SPM) and salicylic acid (SA), plant growth stimulators, are involved in various biological processes and responses to environmental cues in plants. However, the function of their combined treatment on wheat salt tolerance is unclear. In this study, wheat (Triticum aestivum L. cvs. Shandawel 1 and Sids 14) plants were grown under non-saline and saline (6.0 and 12.0 dS m–1) conditions and were foliar sprayed with 100 mgL−1 SA and/or 30 mgL−1 SPM. Exogenously applied SA and/or SPM relieved the adverse effects caused by salt stress and significantly improved wheat growth and production by inducing higher photosynthetic pigment (chlorophyll a, chlorophyll b, carotenoids) content, nutrient (N, P, K+, Ca2+, Mg2+, Fe, Zn, Cu) acquisition, ionic (K+/Na+, Ca2+/Na+, Mg2+/Na+) homeostatics, osmolyte (soluble sugars, free amino acids, proline, glycinebetaine) accumulation, protein content, along with significantly lower Na+ accumulation and chlorophyll a/b ratio. The best response was registered with SA and SPM combined treatment, especially in Shandawel 1. This study highlighted the recovery impact of SA and SPM combined treatment on salinity-damaged wheat plants. The newly discovered data demonstrate that this treatment significantly improved the photosynthetic pigment content, mineral homeostasis, and osmoprotector solutes buildup in salinity-damaged wheat plants. Therefore, it can be a better strategy for ameliorating salt toxicity in sustainable agricultural systems.

Published: November 2022

Glyphosate is a non-selective herbicide and is widely used for weed control in non-cultivated land in China. One susceptible (S) and five putative glyphosate-resistant (R1, R2, R3, R4, and R5) Eleusine indica biotypes were selected to investigate their resistance levels and the potential resistance mechanisms. Based on the dose–response assays, the R3 and R5 biotypes showed a low-level (2.4 to 3.5-fold) glyphosate resistance, and the R1, R2, and R4 biotypes exhibited a moderate- to high-level (8.6 to 19.2-fold) resistance, compared with the S biotype. The analysis of the target-site resistance (TSR) mechanism revealed that the P106A mutation and the heterozygous double T102I + P106S mutation were found in the R3 and R4 biotypes, respectively. In addition, the similar EPSPS gene overexpression was observed in the R1, R2, and R5 biotypes, suggesting that additional non-target-site resistance (NTSR) mechanisms may contribute to glyphosate resistance in R1 and R2 biotypes. Subsequently, an RNA-Seq analysis was performed to identify candidate genes involved in NTSR. In total, ten differentially expressed contigs between untreated S and R1 or R2 plants, and between glyphosate-treated S and R1 or R2 plants, were identified and further verified with RT-qPCR. One ATP-binding cassette (ABC) transporter gene, one aldo-keto reductases (AKRs) gene and one cytochrome P450 monooxygenase (CytP450) gene were up-regulated in R1 or R2 plants. These results indicated that EPSPS overexpression, single or double mutation was a common TSR mechanisms in E. indica. Additional NTSR mechanisms could play an essential role in glyphosate resistance. Three genes, ABCC4, AKR4C10, and CYP88, could serve as important candidate genes and deserve further functional studies.

The indiscriminate use of pesticides in agricultural commodities has become a global health concern. Various household methods are employed to remove pesticide residues from agricultural commodities, e.g., water and ozone. Many ozone-based commercial pesticide removal machines are available in the market for the general public. The current study compares the pesticide removal efficiency of ozone-based washing of fruits and vegetables to simple tap water through commercially available machines and its health risk assessment to different age groups of consumers. The okra and green chili fruits were treated with acetamiprid and ethion as foliar application at the fruiting stage, using the recommended dose (RD) and double to the recommended dose (2RD), respectively. A modified QuEChERS-based pesticide extraction method was verified for its accuracy, precision, linearity, and sensitivity. The treated samples were washed with tap and ozonated water at different intervals, i.e., 3, 8, and 10 min using a commercial food purifier. Washing with ozonized water for 3 min recorded the maximum removal of acetamiprid and ethion from okra and chili fruits. Further, the risk quotient values (RQ) obtained were lower than one at both doses. Thus, washing vegetables with ozonized water for 3 min ensures vegetables are safer for general consumption without any health risk to Indian consumers.
A Comprehensive Review on Amplification of Laser Pulses via Stimulated Raman Scattering and Stimulated Brillouin Scattering in Plasmas

Published: November 2022

The demand for high-intensity lasers has grown ever since the invention of lasers in 1960, owing to their applications in the fields of inertial confinement fusion, plasma-based relativistic particle accelerators, complex X-ray and gamma-ray sources, and laboratory astrophysics. To create such high-intensity lasers, free-running lasers were either Q-switched or mode-locked to increase the peak power to the gigawatt range. Later, chirped pulse amplification was developed, allowing the generation of peak power up to 1012 W. However, the next generation of high-intensity lasers might not be able to be driven by the solid-state technology alone as they are already operating close to their damage thresholds. In this scenario, concepts of amplification based on plasmas has the potential to revolutionize the laser industry, as plasma is already a broken-down medium, and hence does not pose any problems related to the damage thresholds. On the other hand, there are many other aspects that need to be addressed before developing technologies based on plasma-based amplification, and they are being investigated via theoretical and numerical methods and supported by several experiments. In this report, we review the prospects of employing plasma as the medium of amplification by utilising stimulated scattering techniques, such as the stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) techniques, to modulate high-power laser pulses, which would possibly be the key to the next generation of high-power lasers. The 1980s saw the commencement of research in this field, and possibilities of obtaining high peak powers were verified theoretically with the help of numerical calculations and simulations. The extent of amplification by these stimulated scattering schemes are limited by a number of instabilities such as forward Raman scattering (FRS), filamentation, etc., and here, magnetised plasma played an important role in counteracting these parasitic effects. The current research combines all these factors to experimentally realise a large-scale plasma-based amplifier, which can impact the high-energy laser industry in the near future.

Published: November 2022

Replacement of indium tin oxide with the intrinsically conducting polymer poly(3,4–ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has been of significant interest in recent years as a result of lower processing and material costs. In addition, the inclusion of additives has been reported to further enhance the conductivity, rheology, and wettability of PEDOT:PSS. In this study, Tween 80 was shown to decrease the sheet resistance of PEDOT:PSS films from approximately 1000 to 76 Ω□−1 at a 2.67 wt% surfactant concentration. Through X-ray diffraction, Raman spectroscopy, and atomic force microscopy, it was shown that the surfactant caused phase separation and structural ordering of the PEDOT and PSS components, leading to this improvement in conductivity. Furthermore, Tween 80 altered the rheological properties and decreased the surface tension of PEDOT:PSS, making coating common commodity polymers, often used as flexible substrates, more viable.

Published: November 2022

Densely grafted comb-like macromolecules (bottlebrushes) with alternating solvophobic and solvophilic side chains were studied in a selective solvent and at the liquid interface using mesoscopic computer simulations. The effects of backbone length and copolymer composition were considered. While self-assembly in solution revealed only spherical aggregates for all ar-chitectures studied, adsorption onto the liquid interface in particular cases resulted in morpho-logical changes, with worm-like aggregates or a continuous monolayer observed. In turn, the compression of macromolecules at the interface also leads to morphological transitions, includ-ing the formation of a mesh-like percolated structure. The obtained results may be useful for the preparation of solid nanoparticles of anisotropic shape or nanostructured ultra-thin copolymer films.

Published: November 2022

The flow-matching problem of hydraulic systems is an important factor affecting the working performance and energy saving of hydraulic systems. According to the different flow-matching mechanisms, the flow-matching technology of hydraulic systems can be divided into three categories: positive flow-control technology, negative flow-control technology, and load-sensitive control technology. In this paper, the working mechanism of flow-matching technology and the cause of energy loss are analyzed, and the research results of flow matching are introduced from two aspects of energy saving and consumption reduction and system performance improvement. In the direction of energy saving and consumption reduction, the purposes of energy saving and consumption reduction are achieved by means of multi-way valve commutation, independent inlet and outlet control, parallel replacement of shuttle valve by a cylinder piston rod controlled by pilot pressure, change of hydraulic resistance of a pressure compensating valve, improvement of the power regulation range of a hydraulic pump, and potential energy recovery. In the direction of system performance, by means of flow-forecasting system pressure change, applying flow unsaturation real-time control idea, and combining electronic control technology with load-sensitive technology, the pressure drop during transmission process and the transmission signal lag are reduced, the speed regulation interval is enlarged, fine-tuning characteristics are improved, and the response speed is increased. The research results indicate that improving the structure and the control strategy of hydraulic systems and improving the flow-matching degree of a system to achieve global matching will be a future development trend.
E-Word? McLuhan, Baudrillard, and Verisimilitude in Preaching
Authors: Knowles Michael P.
Published: November 2022

Electronic communication of the Christian message—online preaching—raises distinct theological challenges. Notwithstanding the undeniable convenience and unlimited geographical reach of “virtual church”, electronic media have the potential to separate preacher from congregants, congregants from one another, and—potentially of greatest concern—the church from God, even while appearing to accomplish the opposite. Communication theorist Marshall McLuhan (1911–1980) argues provocatively that virtual representation is at the cost of authentic human identity (in which case it is inimical to community), while French sociologist and philosopher Jean Baudrillard (1929–2007) warns of substituting representation for reality, especially in matters of theology and the identity of God. The paradigm of Jesus’ Incarnation, by contrast, mandates un-mediated divine-human and human-to-human communication, requiring engagement between persons themselves rather than their avatars or provisional simulacra. With respect to electronically mediated communication itself, acknowledging divine initiative in the formation of identity (as a feature of soteriology) and of understanding (under the category of revelation) countermands the more dehumanizing and anti-theological influences that McLuhan and Baudrillard both identify, encouraging direct engagement with God in the person of the Holy Spirit rather than resorting to technological mediation.

Authors: Di Battista Silvia , Pivetti Monica , Moro Michele
Published: November 2022

The implementation of Educational Robotics (ER) with special needs students (SNS) has been found to be helpful for knowledge improvement, by keeping students engaged and decreasing the risks of social exclusion. The present study aimed to investigate the relationship between learning support teachers’ (LST) perceptions about ER (i.e., perceptions of usefulness and adaptability) and intention to use ER with SNS. The data were collected via a questionnaire administered to 187 teachers at the end of a post-degree specialisation course. The results showed that LST perceived ER as highly useful for any typology of SNS; however, their perceptions of the usefulness of ER were stronger than their intention to use ER, particularly in the case of neurodevelopmental disabilities. In this case, participants reported that ER is less adaptable than useful and less adaptable with neurodevelopmental disorders than with socio-economic, cultural and linguistic disadvantages. Hierarchical multiple regressions showed that the intention to use ER for neurodevelopmental disorders was predicted by the perception of adaptability and the teacher’s level of experience with ER. As for socio-economic, cultural and linguistic disadvantages, the intention to use ER was predicted by the perception of usefulness and adaptability.

Ruta chalepensis L. (Rutaceae) is a tropical medicinal plant traditionally used in the Republic of Djibouti to treat several diseases, including tumors. In this study, the anticancer activities of this plant from Djibouti were investigated according to an in vitro evaluation method and statistical modeling. The results obtained will make it possible to complete the previous work already published on this genus of plant, in particular by using untested cancer cell lines, such as U87-MG, U2OS, RT4, PC3, NCI-N87, MRC-5, MIA-Paca2, K562, JIMT-T1, HEK293, HCT116, A549, and A2780. The main volatile compound turned out to be 2-undecanone (51.3%). Correlation modeling was performed from the principal component analysis (PCA) of IC50 of the essential oil and four active substances (vinblastine, doxorubicin, combrestatin A4, and monomethyl auristatin E) versus the cancer cell lines tested, which confirmed the effectiveness of the oil against 6 lines: U2OS, NCI-N87, MRC-5, MIA-Paca2, JIMT-T1, and HEK293. These data reveal promising prospects for good biomass management through the future exploitation of the R. chalepensis L. essential oil as a potential source of natural anticancer agents for targeted investigations.
Accountability, Corruption, and Opposition Groups: Evidence from Latin America
Authors: Alcántara-Lizárraga José Ángel , Jima-González Alexandra
Published: November 2022

Under democratic regimes, accountability discourages the existence of corruption, because constituents typically constantly observe public servants. Although every citizen can drive accountability, only a few sectors actively engage in it, such as opposition groups, to a greater extent and for different reasons. Through a comprehensive measure of accountability developed by Varieties of Democracy, which includes vertical, horizontal, and diagonal accountability, this study aims to explore the relationship among the type of opposition in government, level of accountability, and level of corruption, to unravel the relevance of the characteristics of opposition groups when holding a government accountable. Are governments less corrupt when opposition groups from civil society exercise accountability? This study employs latent Markov class analysis applied to Latin America (1980–2020) and concludes that high levels of accountability are achieved and low levels of corruption are evidenced with the existence of opposition groups from civil society.

Published: November 2022

Complexity is a typical feature of space plasmas that may involve the formation of multiscale coherent magnetic and plasma structures. The winding features (pseudo-polarization) of magnetic field fluctuations at different spatial scales are a useful quantity in this framework for investigating complexity in space plasma. Indeed, a strong link between pseudo-polarization, magnetic/plasma structures, turbulence and dissipation exists. We present some preliminary results on the link between the polarization of the magnetic field fluctuations and the structure of field-aligned currents in the high-latitude ionosphere. This study is based on high-resolution (50 Hz) magnetic field data collected on board the European Space Agency Swarm constellation. The results show the existence of a clear link between the multiscale coarse-grained structure of pseudo-polarization and intensity of the field-aligned currents, supporting the recent findings according to which turbulence may be capable of generating multiscale filamentary current structures in the auroral ionosphere. This feature is also examined theoretically, along with its significance for the rate of energy deposition and heating in the polar regions.

Published: November 2022

COVID-19 vaccination acceptance among healthcare workers (HCWs) is very important to control the pandemic and to ensure the safety of HCWs and patients. As psychological factors may affect the decision to be vaccinated, the aim of this study was to investigate the influence of psychological factors on vaccination acceptance in different phases of the COVID-19 pandemic. A cross-sectional study using a web-based survey was conducted among HCWs in Slovenia at the beginning of the pandemic (N = 851), one month later (N = 86), and one year later (N = 145) when vaccines were already available. The results showed that the influence of psychological factors (anxiety, psychological burden, perceived infectability, and germ aversion) was specific for each survey period. At the beginning of the pandemic, vaccination intention was positively associated with anxiety. In the third survey period, anxiety was not exposed as a predictive factor for vaccination intention. However, comparison of vaccination status among groups with different levels of anxiety revealed an interesting distinction within those in favour of vaccination; in the group with minimal levels of anxiety, there was a relatively high share of respondents that were already vaccinated, whereas in the group with severe anxiety, most individuals intended to be vaccinated but hesitated to take action.

Published: November 2022

Background: Vaccination against COVID-19 has had a major impact over the course of the pandemic, leading to a reduced number of hospitalizations and deaths. However, the mass vaccination process has been accompanied by skepticism and hesitancy since its beginning. As health professionals and teachers are important public health actors who can strongly intervene to reduce vaccination hesitancy among their patients and students, respectively, this study aimed to assess their main perceptions towards COVID-19 vaccination. Methods: Two focus group sessions, one with health professionals and the other with teachers, were conducted according to the COREQ checklist. Qualitative data were analyzed through theoretical thematic analysis. Results: In general, none of the groups showed vaccine hesitancy, although both groups had concerns regarding the safety and efficacy of the vaccines. The main concerns of health professionals were mostly related to the long-term impact of the COVID-19 pandemic, while teachers were more worried about the lack of access to reliable information about the COVID-19 vaccination. Conclusions: It is plausible to conclude that it is imperative to provide clear and accurate information for the population in order to avoid vaccination hesitancy.

As installed photovoltaic panels (PVPs) approach their End of Life (EoL), the need for a sustainable recovery plan becomes imperative. This work aims to reuse silicon from EoL PVPs as a potential catalyst/photocatalyst for wastewater treatment. PVPs were pretreated thermally. The resulting mixture was separated into different fractions using a trommel screen. Recovered silicon flakes were cleaned with HΝO3 and HF in order to obtain pure Si, which was then etched through a single stage Ag-assisted Chemical Etching process and decorated with Ag/Cu. Photocatalytic reduction of Cr(VI) in the presence of 5 mM citric acid was carried out in a 600 mL batch reactor irradiated by a Xenon 150 W arc lamp as well as under dark conditions. It was found that, in the presence of 1.2 g/L of Si catalyst, Cr(VI) at an initial concentration of 15 mg/L can be reduced below the detection limit (>99%), even under dark conditions, in 30–180 min, depending on the pH of the solution and the citric acid concentration. Citric acid was proved to assist the reaction in three ways: lowering the pH, increasing the solubility of the precipitate, preventing inhibition, and as sacrificial agent in photocatalysis. Irradiation, however, was shown to possibly inhibit the process if the citric acid concentration is low.

O presente ensaio tem como objetivo apresentar, enquanto performa, uma discussão acerca das representações de realidade empreendidas por certas obras de arte e também por documentos históricos. Com tal propósito, tenciona-se também a ideia de ficção e suas implicações estéticas e políticas nas sociedades ocidentais, e observar-se como esse empreendimento constrói uma zona institucional e perigosa, ainda que fictícia, entre a verdade e a irracionalidade.

Orgulho e Preconceito (1813), de Jane Austen: subversão e submissão a partir das personagens Elizabeth e Jane Bennet
Authors: De Pontes Francisco Edinaldo , Brito da Conceição Francis Willams
Published: November 2022

Este trabalho analisa as caracterizações das irmãs Elizabeth e Jane Bennet como representações da subversão e da submissão na Inglaterra oitocentista. No romance Orgulho e Preconceito (1813), de Jane Austen, a investigação se baseou nos aspectos discursivos e comportamentais das personagens irmãs, a partir de leituras de Millett (1970), Muraro (2002), Woolf (2019), dentre outros. Ademais, partiu-se da seguinte hipótese: Elizabeth subverte-se através da fuga do casamento e do apego à leitura, enquanto Jane submete-se pela candura e neutralidade.
Projeto de instrumentação, monitoramento por imagens e retroanálise de pavimento
Authors:   , Mendes Douglas de Castro
Published: November 2022

As ferrovias têm ganhado destaque nacional em razão dos vultosos investimentos e expansões da malha planejados para os próximos anos. Os métodos brasileiros para analisar o comportamento dos pavimentos ferroviários, no entanto, apresentam simplificações defasadas e inspiradas em países com solos de climas distintos das 5 regiões climáticas do Brasil. Dessa forma, esta dissertação, peça integrante do Termo de Execução Descentralizado (TED) entre o Departamento Nacional de Infraestrutura de Transportes (DNIT) e a Universidade de Brasília (UnB) em parceria com a Universidade Federal de Juiz de Fora (UFJF), colabora com a execução de um trecho experimental (TE) composto por instrumentação específica para medir as tensões, as deformações e as modificações nas condições dos materiais do pavimento ferroviário resultantes das ações do tráfego. Para tanto, definiu-se os instrumentos que integrarão o TE, tendo como referência as poucas experiências nacionais e internacionais. Da instrumentação projetada, utilizou-se somente a medição das deflexões por meio do tratamento de imagens quando da passagem do trem, deixando o legado para futuras pesquisas. Em consonância a essas experiências, o monitoramento das deflexões por meio de imagens digitais, utilizada na pesquisa, apresentou-se como um diferencial. O projeto de instrumentação foi norteado por uma prévia modelagem numérica, com uso do software SysTrain. Assim, procedeu-se com o monitoramento do potencial trecho a ser instrumentado, sendo realizadas filmagens que captassem o deslocamento de alvos locados em trilhos e em dormentes. Em seguida, foi realizada retroanálise no SysTrain, a partir da deflexão do trilho e validando-a com os deslocamentos dos dormentes, uma vez que houve consonância entre os resultados modelados e de campo. Pelo tipo de retroanálise analisada, constatou-se módulo de resiliência com valor indicativo de processo avançado de degradação do subleito. Condição razoável considerando o tempo de operação da via. Por meio de análises de sensibilidade dos parâmetros que podem afetar o comportamento do pavimento férreo, verificou-se a influência do módulo de resiliência, principalmente do subleito, nos deslocamentos mobilizados no trilho. Por outro lado, não houve impacto significativo da condição do lastro no comportamento do pavimento analisado. Assim, os resultados destacam a importância da iteração entre as camadas do pavimento e da condição do subleito para um melhor desempenho da linha férrea.
Biomas brasileiros em história em quadrinhos: sequência didática como estratégia de aprendizagem significativa

Published: November 2022

A informatização do conhecimento é parte do processo de ensino-aprendizagem da atual geração, mesmo sendo uma novidade para a geração anterior, que apesar de utilizá-la para fins pessoais, ainda têm receio de aplicá-la na prática docente, e altamente abstrato para os professores que estão no magistério há muitos anos. Esse fato foi claramente observado em 2020, com as significativas mudanças na relação entre professores e alunos, intermediadas por plataformas remotas de ensino, devido às ações de enfrentamento da pandemia de COVID-19. O presente trabalho elaborou uma sequência didática (SD) envolvendo o conteúdo de ecologia sobre biomas brasileiros, na perspectiva da aprendizagem significativa de David Ausubel, integrando e ancorando os conteúdos apresentados nas estruturas cognitivas dos estudantes. A SD desenvolvida e aplicada foi dividida em etapas: 1. pesquisa quali-quantitativa, utilizando a estratégia de etiqueta em nuvens e a técnica de Brainstorming em ambiente virtual; 2. aula síncrona ou presencial, para elaboração de mapa conceitual; 3. aula expositiva/dialógica sobre as principais características de biomas, com ênfase nos biomas brasileiros; 4. criação dos grupos de trabalho e fichamento de um bioma brasileiro por grupo; 5. elaboração de história em quadrinhos sobre um dos biomas, utilizando ferramentas virtuais e/ou aplicativos para smartfones; 6. desenvolvimento de aplicativos que apresentem as histórias criadas e 7. processo avaliativo. Os resultados apontaram que na etapa da pesquisa, os alunos apresentavam os subsunçores necessários para a ancoragem da aprendizagem, uma vez que as palavras presentes nas nuvens e os conceitos utilizados nos mapas tinham conexão direta com o conteúdo; a aula expositiva/dialógica serviu como contextualização; a separação dos grupos e a confecção dos fichamentos ocorreu de forma parcimoniosa, e dentro do prazo; a elaboração e apresentação das histórias em quadrinhos (HQ) demandaram tempo e esforço maior do que o planejado, mas todas as equipes lograram êxito; cada grupo elaborou a HQ com ferramentas digitais diferentes, ou seja, ocorreu cartunização de imagens, criação de personagens a partir de aplicativos e utilização de personagens pré-existentes em editores vetoriais. Com o avançar do período letivo, não foi possível concluir, totalmente, a etapa do desenvolvimento de aplicativos e o processo avaliativo demonstrou avanços em relação ao empoderamento dos conceitos trabalhados.
Avaliação de gaps marginais e da qualidade da imagem de coroas confeccionadas em dois diferentes materiais restauradores: um estudo in vitro com imagens de TCFC
Authors:   , Doriguêtto Paulo Victor Teixeira
Published: November 2022

O objetivo do estudo foi avaliar a qualidade das imagens e a presença de desadaptações marginais em imagens de tomografia computadorizada de feixe cônico (TCFC) de dentes restaurados com coroas totais metalocerâmicas e em cerâmica pura, comparando os tamanhos de gaps observados em imagens de TCFC com aqueles obtidos em imagens de microtomografia computadorizada (micro-TC). Para tanto, um total de 30 dentes restaurados com coroas metalocerâmica (n = 15) e cerâmica pura (n = 15), devidamente adaptadas e com gaps de 0,30 e 0,50 mm, foram submetidos a exames de micro-TC e TCFC. Medidas lineares correspondentes ao gap marginal (GM) e a discrepância marginal absoluta (DMA) foram obtidas nos dois exames de imagem. A avaliação objetiva da qualidade das imagens de TCFC foi feita através da taxa contraste-ruído (TCR), e a avalição subjetiva da qualidade das imagens de TCFC foi conduzida por cinco examinadores que avaliaram a presença ou ausência de gaps. Para comparação dos valores de GM e DMA entre os exames de TCFC e micro-TC, e da TCR entre os diferentes materiais restauradores foi utilizado o teste de Mann Whitney. Valores de sensibilidade, especificidade e acurácia, determinada por meio da área sob a curva ROC, foram calculados para cada tipo de coroa e tamanho de gap. Os valores de desadaptação marginal foram sempre superiores na TCFC, com diferença significativa para a DMA. Não foi observada diferença significativa na qualidade da imagem, por meio da TCR, entre as duas coroas testadas. Foram observados baixos valores de acurácia e sensibilidade para ambas as coroas, independentemente do tamanho do gap. Já os valores de especificidade foram maiores para as coroas metalocerâmica do que para as coroas confeccionadas em cerâmica pura. Pode-se concluir que as imagens de TCFC superestimaram as medidas de desadaptações marginais. Não foi observada diferença na qualidade da imagem entre as coroas testadas. Os valores de acurácia e sensibilidade foram considerados baixos, independentemente do tipo de coroa e tamanho do gap
"Eu sou bicha, eu sou gay, eu sou viado, eu sou o que você quiser”: pequenas histórias de drag queens da cidade de Juiz de Fora (MG)
Authors:   , Ferreira Ludmila Mendes
Published: November 2022

O presente estudo, de base qualitativa interpretativista, busca tecer possíveis reflexões sobre as performances linguísticas de drag queens da cidade de Juiz de Fora (MG), de forma a contribuir para os estudos da linguística aplicada indisciplinar, transgressiva de desaprendizagem. Compreendido que as performances de drag queens são estilos parodísticos e reiterações estilísticas com potencial crítico de subversão de sistemas sexistas, a proposta de uma análise discursiva dessas performances possibilita uma reflexão linguística decolonial, antiessencialista, que perpassa questões de gênero e sexualidade. Com base nos estudos de análise de narrativas, que emergem das entrevistas semiestruturadas realizadas com as drag queens, propõe-se uma reflexão a respeito do repertório biográfico dessas artistas sob a ótica da práticas translíngues, afastando-se de perspectivas monolíticas e colonialista de linguagem. Partindo dos estudos decoloniais e das epistemologias do Sul, bem como atrelandose a questões de gênero e sexualidade, que perpassam a subjetividade dessas artistas, procurase pensar na importância de sair de um conceito limitador de língua, que potencialmente invisibiliza e marginaliza seus repertórios. Para tanto, a presente pesquisa é dividida em sete capítulo: 1) Introdução; 2) Performatividade Drag: Teorias e Discussões; 3) Decolonialidade: Resgatando os Saberes Ausentes; 4) Ideologias, Performatividade e Práticas Translíngues; 5) Metodologia; 6) Reflexão Sobre os Dados; 7) (In)Conclusões. As discussões propostas, com base nas perspectivas epistemológicas mencionadas, buscam traçar caminhos teóricos e analíticos para os estudos linguísticos contemporâneos transdisciplinares que visam justiça social e cognitiva
