Introduction: Quality of life is a multifaceted construct that depends on the person’s subjective perception; however, some studies have shown self-efficacy and cognition with possible indicators of this positive perception of quality of life in people. Objective: Examined prediction of Quality of Life (QL) and its domains according to self-efficacy, physical activity (PA) and cognition among elderly people attending public Open Universities for the elderly in the State of Paraná, Brazil. Method: Cross-sectional descriptive correlational study with a sample of 277 elderly. Questionnaires used: Sociodemographic, WHOQOL-BREF and WHOQOL-OLD, IPAQ, General Perceived Self-Efficacy Scale and Addenbrooke’s Cognitive Examination. Statistical: Descriptive and inferential analysis (correlation and multiple linear regression), significance p < .05. Results: The mean age was 67.60 (SD=6.65). Self-efficacy was related to QOL and to all domains. PA correlated with general QOL and the Psychological and Social domains. Cognition was correlated with general QOL and five other domains (Physical, Psychological, Social, Environmental, Sensory functioning, Past/Present/ Future Activities). Self-efficacy, PA and Cognition can explain 10% of the general QOL, and 14% of the Environmental domain. The specific QOL and its domains had 10% of explanation. Conclusion: QOL can be explained by the constructs self-efficacy, cognition and PA.

Within-host models of dengue virus transmission with immune response
Authors: Muthu Poosan , Modak Bikash
Published: May 2023

Dengue fever is an infectious viral fever. The complex behavior of the virus within the body can be explained through mathematical models to understand the virus’s dynamics. We propose two different with-in host models of dengue virus transmission with humoral immune response. The proposed models differ from one another because one of the models assumes that newly formed viruses infect healthy cells again. To understand the dynamics of the proposed models, we perform a comparative study of stability analysis, numerical simulation, and sensitivity analysis. The basic reproduction number (BRN) of the two models is computed using next-generation matrix method. The local stability (l.s) analysis is discussed using the linearization method. The Lyapunov’s direct method is used to check the global stability (g.s) of the models. It has been found that both the equilibrium states for both the models, namely, virus-free equilibrium state and endemic equilibrium state, are globally stable, based on the value of BRN. Results show the influence of immune response on the cell dynamics and virus particles. The virus neutralization rate by antibodies and rate that affects the antibody growth are highly sensitive for the two models. Optimal control is applied to explore the possible control strategies to prevent virus spread in the host system. It is evident from the results that the strategy to administrate antibiotic drugs and home remedies slow down the virus spread in the host.

Published: May 2023

Vehicles, regardless of the type of drive, move on different types of roads. The operational characteristics of the highway will be different than those of the urban road. The aim of this article is to compare the performance of electric, hybrid, and conventional vehicles on different roads. For simulation studies in the AVL Cruise program, speed profiles determined on the highway, expressway, suburban, and urban roads were used. The article presents the course of energy consumption of an electric and hybrid vehicle, the amount of energy recovered by these vehicles, and the state of battery charge after the routes. The fuel consumption and emissions of harmful exhaust components of hybrid and conventional vehicles are also described. Based on the collected data, it was determined what is the cost of driving each of the routes by the tested vehicles. The results showed that the operational characteristics of the vehicles on each route are different. Driving speed, vehicle load, or duration of the journey significantly affects energy consumption, fuel, and costs. Such a comparison allows you to adjust the choice of vehicle by the driver, who, knowing his daily route, can decide on a vehicle with a specific type of drive.
Synergism between lignite and high-sulfur petroleum coke in CO2 gasification
Authors: Mao Lirui , Liu Tao , Zhao Yanlin , Zheng Mingdong
Published: May 2023

High-sulfur petroleum coke (PC) as solid waste has high treatment cost. Gasification technology can utilize PC and lignite for co-gasification. Organically combining the two is the key to expanding the adaptability of gasification raw materials. This work used thermal analysis technology to study the gasification reaction of PC and lignite systems in a CO2 atmosphere. The results show that the starting and end temperatures of the co-gasification of lignite/high-sulfur PC are lower than those of pure coke. The improved carbonization rate and gasification reaction index indicate that lignite improves the gasification performance. The gasification synergy factors are all greater than 1, indicating that the co-gasification process produces obvious synergism, and the synergism is more obvious in the gasification stage after 800°C. The lignite ash is gradually enriched on the surface of high-sulfur PC with the temperature increase, and the Ca and Fe elements have an obvious catalytic effect, but the catalytic effect has a saturation value. Ashes from lignite used as a multi-component gasification catalyst can increase the overall reactivity in the lignite/high-sulfur PC system, which can broaden the selection of gasification raw materials, and make efficient use of the resource characteristics of both.
Illuminating the brain-genetically encoded single wavelength fluorescent biosensors to unravel neurotransmitter dynamics
Authors: Kubitschke Martin , Masseck Olivia A.
Published: May 2023

Understanding how neuronal networks generate complex behavior is one of the major goals of Neuroscience. Neurotransmitter and Neuromodulators are crucial for information flow between neurons and understanding their dynamics is the key to unravel their role in behavior. To understand how the brain transmits information and how brain states arise, it is essential to visualize the dynamics of neurotransmitters, neuromodulators and neurochemicals. In the last five years, an increasing number of single-wavelength biosensors either based on periplasmic binding proteins (PBPs) or on G-protein-coupled receptors (GPCR) have been published that are able to detect neurotransmitter release in vitro and in vivo with high spatial and temporal resolution. Here we review and discuss recent progress in the development of these sensors, their limitations and future directions.
Revisiting after-class boredom via exploratory structural equation modeling

Published: May 2023

Boredom has recently become the subject of inquiry in L2 studies, which has resulted, among others, in the development and validation of several boredom-measuring scales, mostly through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). However, such analytical procedures are not free from limitations and exploratory structural equation modeling (ESEM) can be applied to overcome them. CFA has also been used to validate the Boredom in Learning English Outside of School Questionnaire (BLEOS), an instrument which taps into recently conceptualized after-class boredom, revealing the extent to which students are likely to feel bored when they attempt to practice the target language outside the classroom as well as factors underpinning this negative emotion in such contexts. The present study sought to revisit the BLEOS scale to determine (1) whether the factor structure of the BLEOS is supported by ESEM and bifactor ESEM, (2) how stable the results are across gender, and (3) the criterion-related validity of the BLEOS scale. In doing so, the CFA and ESEM models (i.e., standard and bifactor CFA as well as standard and bifactor ESEM models) were compared to identify which model(s) would exhibit better fit indices for the measure in question. A total of 433 students majoring in English, 120 males and 313 females, participated in this study. It was revealed that while the CFA model provided an inflated factor correlation and unacceptable model fit to the data, ESEM (especially bifactor ESEM) indicated a realistic representation of the data with a good fit. The bi-factor ESEM model of the BLEOS turned out to be stable across gender. Finally, the structural bifactor ESEM model of BLEOS proved to explain learning outcomes modestly.
Factors behind L2 English learners’ performance of oppositional speech acts: a look at pragmatic-related episodes (PREs) during thinking aloud
Authors: Kang Dae-Min
Published: May 2023

The current study looked at the influence of different L1s, different proficiency levels, and other factors on the think-alouds in connection with oppositional speech acts by eighty tertiary-level Korean and Chinese learners of L2 English at two proficiency levels. The research instruments consisted of think-aloud protocols elicited during the learners’ production of written oppositional speech acts in the form of responses to the other learners’ essays, questionnaires, and focus group interviews. In particular, in the think-aloud protocols the number and content of pragmatic-related episodes (PREs) were identified. The results indicated that proficiency level, but not L1, significantly impacted the learners’ think-alouds. Other factors were revealed to include intensification of claims, focus on face issues, pragmatic transfer, and insufficient syntactic/semantic knowledge. These factors related to the sub-categories of the PREs involving ‘lexical upgrading’ and ‘external downgrading’.
Effect of Annona squamosa leaf extract on human promyelocytic leukemia cells subjected to oxidative stress
Authors: Dilworth Lowell L. , Stennett Dewayne K. , Bailey Dennis H. , Omoruyi Felix O.
Published: May 2023

Objectives

Annona squamosa has beneficial properties. However, its cytotoxicity and antioxidative effects on human promyelocytic leukemia cells (HL60) deserve investigation. Therefore, the efficacy of its crude extracts in offsetting damage in HL60 cells subjected to oxidative stress was studied.

Methods

Crude extracts at different concentrations were incubated with HL60 cells. The beneficial properties of the plant extract against oxidative damage were evaluated post-induction of oxidative stress utilizing hydrogen peroxide.

Results

Extracts at concentrations 600 and 800 μg/mL were most effective at increasing the viability of damaged cells compared to the control group after 48 h of incubation. Significant increases in lipid peroxidation were observed in exposed cells treated with 600 μg/mL extract after 72 h of incubation. Superoxide dismutase (SOD) and catalase activities significantly increased in exposed cells after 24 h of incubation at all extract concentrations. Exposed cells treated with 600 and 1,000 μg/dL of the extract showed significantly increased catalase activity after 48 h, and a similar profile was maintained after 72 h of exposure. SOD activity in exposed cells remained significantly increased at all treatment concentrations after 48 and 72 h of incubation. Treatment with 400, 600, and 800 μg/mL of the extract resulted in significantly increased reduced glutathione levels compared to the other groups after 24 and 72 h of incubation. However, after 48 h of incubation, significant increases were noted in glutathione levels in exposed cells incubated with either 400, 800, or 1,000 μg/mL extract.

Conclusions

The findings suggest that A. squamosa might effectively protect against oxidative damage in a time and extract concentration-dependent manner.

This paper explores defensive play in soccer. The analysis is predicated on the assumption that the area of the convex hull formed by the players on a team provides a proxy for defensive style where small areas coincide with a greater defensive focus. With the availability of tracking data, the massive dataset considered in this paper consists of areas of convex hulls, related covariates and shots taken during matches. Whereas the pre-processing of the data is an exercise in data science, the statistical analysis is carried out using linear models. The resultant messages are nuanced but the primary message suggests that an extreme defensive style (defined by a small convex hull) is negatively associated with generating shots.
Medical operational AI: artificial intelligence in routine medical operations
Authors: Berns Fabian , Heilig Niclas , Stumpe Florian , Kirchhoff Jan
Published: May 2023

Despite substantial gains facilitated by Artificial Intelligence (AI) in recent years, it has to be applied very cautiously in sensitive domains like medicine due to the lack of explainability of many methods in this field. We aim to provide a system to overcome these issues of medical AI applications by means of our concept of medical operational AI detailed in this paper. We make use of various methods of AI and utilize knowledge graphs in particular. The latter is continuously updated by medical experts based on medical literature such as peer-reviewed papers and standard online sources such as UpToDate. We thoroughly derive a multi-level system tackling the corresponding challenges. In particular, its design encompasses (i) holistic diagnostic assistance on a macro level, (ii) predicitions and detailed suggestions for specific medical domains on a micro level, as well as (iii) AI-based optimizations of the overall system on a meta level. We detail practical merits of medical operational AI and discuss the state of the art beyond our solution.
A visualization tool for continuous reference intervals based on GAMLSS
Authors: Klawitter Sandra , Kacprowski Tim
Published: May 2023

Reference intervals are an important component in the interpretation of medical laboratory findings. Especially in children and adolescents, their limits sometimes can change very rapidly with age. We suggest continuous methods to better represent the age-dependent progression of reference intervals. The generalized additive models for location, scale, and shape parameters (GAMLSS) from the R package gamlss generates continuous percentile plots of laboratory values. A user-friendly Shiny application called AdRI_GAMLSS (Age-dependent Reference Intervals), available at github.com/SandraKla/AdRI_GAMLSS, has been developed for this purpose. Using alkaline phosphatase (ALP) as an example, we obtain different smoothed percentile curves depending on the model used. We demonstrate the superiority of continuously modeled reference intervals compared to fixed age groups and provide the Shiny application AdRI_GAMLSS to make the technique easily accessible to clinicians and other experts.
Extending the Interdependence Theory to Local Public Service Provision: Evidence from Iowa
Authors: Shafiq Saman , Albrecht Kate , LeRoux Kelly
Published: May 2023

Lester Salamon’s interdependence theory has held up over time and across dozens of national contexts. However, the theory has largely been developed through data on government partnerships with nonprofits for providing social services. While government-nonprofit partnerships exist in various service areas and policy contexts, the theory has rarely been applied in less “traditional” service settings. We apply a mixed-method sequential research design – empirical analysis followed by a comparative case analysis – to understand the descriptive and explanatory power of Salamon’s interdependence theory and to differentiate its applications from other theories of government-nonprofit partnerships. Our analysis shows that nonprofits are extensively engaged in public service delivery at the local level, partnering with county and municipal governments to carry out essential public services well beyond the scope of social welfare functions and human services. Expanding the concept of interdependence theory, our findings further show that in local service delivery settings, there is a unique balancing of aspects of both voluntary and government failure that can be achieved.

Collusive Bidding, Competition Law, and Welfare
Authors: Gangopadhyay Shubhashis , Mallios Aineas , Sjögren Stefan
Published: May 2023

We explain why competing firms form collective entities to buy patents from other entities, particularly from non-practicing entities (NPEs), and follow a catch and release patent strategy. We show why having competitors bid as a single unit is better than having competitors bid against each other. More important, we show that collusive bidding on patents held by NPEs, even when the patents are not essential for a standard (SEPs), may increase consumer surplus, particularly when technological innovation is drastic, and improve social welfare. This provides a theoretical foundation that explains why competition authorities often allow collusive bidding for patents and why courts employ the “rule of reason” to analyze agreements under competition law. We also show that a cartel of incumbents will always outbid a potential entrant, or a patent assertion entity, over a technology that can destroy the value of the incumbents’ existing assets.
Welfare cost of inflation, when credit card transaction services are included among monetary services
Authors: Barnett William A. , Park Sohee
Published: May 2023

We investigate the welfare cost of anticipated inflation, when the volume of credit card transactions is included in measured monetary service flows. We use the credit-card-augmented Divisia monetary aggregates in a nonlinear dynamic stochastic general equilibrium (DSGE) New Keynesian model and calculate the welfare costs of inflation. The welfare costs of inflation with credit card services included are greater than without them in the New Keynesian DSGE model. Because of the complexity of the model’s dynamical structure, we are not aware of a simple explanation for the increased welfare sensitivity to inflation.
Unsteady temperature distribution in a cylinder made of functionally graded materials under circumferentially-varying convective heat transfer boundary conditions

Published: May 2023

A novel model on 2D unsteady conductive heat transfer in an infinite hollow cylinder is proposed. The cylinder is made of functionally graded material (FGM) that has variable properties both in radial and angular directions. Volumetric heat capacity and thermal conductivity coefficient are changed according to the power function of the radius. In the presence of variable coefficients, the governing equations of unsteady heat transfer in FGMs have caused the complexity. The Laplace transform method is used to transfer the energy equation from time to frequency domain whereas the meromorphic function is used for the inverse Laplace transform to obtain the desired solutions. The closed form solutions have been well validated and the results have been presented for different values of functionally graded indices for thermal conductivity coefficients and volumetric heat capacity. Two different FGM cases with different complicated thermal boundary conditions have been investigated. The first case has a constant temperature in the inner radius and a variable heat flux along with the convection condition in the outer radius. In the second case, the inner radius has a specific harmonic temperature and the outer radius is exposed to the convective conditions. It was observed that in both cases, the temperature value in the cylinder decreases with the increase of the FG index for the conductivity coefficient. The presented analytical solution provides a good tool for validating unsteady numerical solutions presented in the field of heat transfer in FGMs.

Heavy metals presence in the potable water is a terrible dilemma notably for emergent countries and could be carcinogenic. Currently, interfacial polymerization (IP) was applied for the production of thin film nanocomposite forward osmosis (TFN-FO) membrane using polyacrylonitrile support. For this purpose, Zn (II)-imidazole metal Organic framework (MOF) was employed as a nanofiller into polymeric membranes this modification was found useful for the removal of heavy metals. Different characterization techniques like scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDS), Fourier transform infra-red spectroscopy (FTIR) and X-ray diffraction (XRD) analyses were used for the assessment of morphology, elemental arrangement, functional groups and crystalline nature of the prepared FO membrane. It was observed that synthesized Zn-MOF based FO membrane displays high water flux by increasing the number of pores in the membrane. Additionally, this particular FO membrane was custom-made for lower reverse solute flux and concentration polarization. This ensures minimum withdrawal of salt from the draw solution (DS) to the feed solution (FS). So, the prepared Zn-MOF based FO membrane produce synergistic outcomes for the removal of metals and this strategy could possibly be used as novel way for removal of toxic pollutants.

CAMADAS NARRATIVAS NO CINEMA: LISBELA E O PRISIONEIRO E MISE EN ABYME
Authors: Steindorff Gabriel , Piccinin Fabiana
Published: May 2023

O artigo discute a metanarrativa como recurso estruturador da narrativa fílmica mediante o estabelecimento de níveis diegéticos autorreferentes e articulados entre si. Dessa maneira, a narrativa fílmica objetiva estabelecer a ideia de cumplicidade e de identificação entre o narrador protagonista e o espectador por meio do efeito de mise en abyme que consiste na duplicação sucessiva e infinita da obra de arte ao projetar-se para dentro ou, de forma imaginária, para fora. Para refletir sobre a perspectiva metanarrativa no cinema observa-se a problemática na dimensão empírica a partir da performance da narradora protagonista Lisbela do filme Lisbela e o Prisioneiro (2004) de Guel Arraes, que, ao expor a estrutura narrativa do filme, indica conhecer muito bem o mundo da diegese, ao mesmo tempo em que age como quem paradoxalmente não estivesse dentro de um universo ficcional. Desta forma, Lisbela é capaz de prever e adiantar ao espectador os acontecimentos da narrativa do próprio filme em que está inserida.Palavras-chave: Narrativa; metalinguagem; metaficção; filme; Lisbela e o Prisioneiro. NARRATIVE LAYERS IN CINEMA: LISBELA E O PRISIONEIRO AND MISE EN ABYME Abstract: The article discusses the metanarrative as structuring resource from film narrative by establishing of self-referential diegetic levels and articulated by them. Thus the narrative film objectify to establish an idea of complicity and identification between the protagonist storyteller and the viewer by a mise en abyme effect which consists of successive and endless duplication of the work of art to be projected into or, in an imaginary way, out. Thinking about the cinema metanarrative perspective, we observe the empiric proportion starting from the performance of the protagonist storyteller Lisbela, in the movie Lisbela e o Prisioneiro (2004), by Guel Arraes. The character, while exposing the narrative structure of the film, shows us diegesis expertise and she acts as if paradoxically were not in a fictional universe. Thus, Lisbela is able to predict and anticipate to the viewer the narrative of the events of the film in which plays a role.Keywords: Narrative; metalanguage; metafiction; film; Lisbela and the Prisoner.

Em nossa época, percebemos uma atração constante das linguagens e dos meios. A narrativa se torna hiper e o espectador se liberta da linearidade com o uso de teias - redes – links, que permitem um fluxo amplo e complexo num trânsito de infinitas narrativas, por exemplo, Kiko Goifman com o filme 33; Alexandre Carvalho com o filme FLUÍDOS. Estes são exemplos de produtos audiovisuais que passaram por traduções, transformações via convergência de linguagens ou hibridismo entre diferentes mídias. Portanto, o cinema sai de seu lugar comum – as salas de exibição – caracterizando assim, a desterritorialidade e a invasão em novos panoramas, ampliando a complexa linguagem cinematográfica em ambientes virtuais.Palavras-chave: Narrativas; convergência; arte; cinema; documentário. CONTEMPORARY BRAZILIAN CINEMA AND ITS NARRATIVE TENDENCIESAbstract: Currently, we perceive a constant attraction to languages and media.

Dando continuidade à série fotográfica Meu ponto de vista, iniciada em 2002, onde realizo a fotografia em frente a pia do banheiro do apartamento que residia naquele momento e constato que a minha imagem não era captada pelo reflexo do espelho fixado muito acima da altura do meu olhar, percebo a recorrência deste tipo de fotografia que segue, desde aquele período até hoje, este mesmo protocolo. Organizo estas imagens agrupando-as dentro de uma nova série intitulada Meu ponto de vista: check-in, que tem a intenção de ampliar os locais a serem captados, locais estes para além do meu convívio íntimo diário, onde busco aproximar-me, busco intimidade. As imagens escolhidas são ampliadas, reagrupadas em séries e testadas em sua forma de apresentação.Palavras-chave: Fotografia; ponto de vista; protocolo; séries fotográficas; modos de apresentação. My point of view: check-inAbstract: This paper discusses the continuing photographic series My point of view, which has been in development since 2002, and which involved taking photographs in front of the bathroom sink of the apartment where I had been living and at that moment when I noticed that my image was not captured by the reflection in the mirror, attached to the wall far above the height of my gaze. I have perceived the recurrence of this type of photographic situation since that period until today, and still use the same protocol. I have organized these images, grouping them into a new series entitled My point of view: check-in, which has the intention of expanding on the locations where images may be captured, places that go beyond my close daily interactions, where I try to get closer and to seek intimacy. I discuss some chosen images which have been enlarged and regrouped in series and their experimented presentational forms. Keywords: Photography; point of view; protocol; photographic series; modes of presentation.
Diferença Colonial Como Episteme das Artes de Exterioridade Latino-Americanas
Authors: Bessa-Oliveira Marcos Antônio
Published: May 2023

Diferença colonial é re-existência dos oprimidos na exterioridade por práticas/teorias hegemônicas geoistóricas. Tal discussão dar-se-á na ex-posição de gentes-sem-corpos, por teorias descoloniais contracartesianas, corpos in-visíveis aos sistemas imperantes presentes na América Latina que apagam por não-representação na cultura e sociedade das diferenças. Argumentamos que corpos invisíveis re-existem. Palavras-chave: Artes; diferença; exterioridade.  Colonial Difference as Episteme of the Arts ofLatin American Exteriority Abstract: Colonial difference is the re-existence of the oppressed in relation to exteriority through hegemonic geo-historical practices/theories. Such a discussion will take place in the ex-position of people-without-bodies, by counter-Cartesian decolonial theories, bodies invisible to the prevailing systems present in Latin America that erase by non-representation in culture and society of differences. We argue that invisible bodies re-exist. Keywords: Arts; difference; exteriority.Deve ser evitado colocar keywords e abstrato aqui, o texto deve iniciar na pagina parte.
Quando Pequeno o Patio Parecia Maior
Authors: Montelli Eduardo
Published: May 2023

O ensaio visual de Eduardo Montelli apresenta uma série de imagens fotográficas imbricadas em um texto que, à primeira vista, dão a impressão de que o artista está contando um relato sobre sua casa de infância, como se a estivesse mostrando para um visitante. No entanto, é o artista quem revisita esta ‘casa’ por meio de seus registros digitais, ao realizar um passeio virtual pelos arquivos postados e guardados em sítios e blogs desde 2007. Em sua passagem pelo tempo do arquivo, Montelli remonta memórias que evocam a fala simples do olhar da criança que já não é mais. Num momento, o ensaio se parece a um álbum de fotos de família, noutro, é um diário de bordo do artista que registra suas ideias emergentes, contaminações por artistas referentes, a descoberta de materialidades caseiras – cestas, gaiolas – experimentações cruas do quintal e documentos de trabalho. O que movimenta o artista ao transitar da fotografia para a produção de vídeo? Montelli aponta para uma acumulação de ideias e imagens instantâneas que se transbordam como algo que cresce muito tempo no quintal, para encontrar, neste contexto, uma base sólida para seu processo criativo que interroga a imagem e o arquivamento digitais.Palavras-chave: Ensaio visual; processo criativo; quintal; fotografia digital;  arquivamento.  When Small, the Patio seemed bigger Eduardo Montelli's visual essay presents a series of photographic images and a text that, at first glance, might seem to be him recalling childhood memories,  as if he were showing rooms of the  house where he grew up to a visitor. But it is the artist who revisits this 'house' through his digital records, as he takes a virtual tour of his photographic files posted and stored on websites and blogs since 2007. In his passage through the time of the archive, Montelli speaks of memories that evoke the simple ways he used to see his own backyard, as the child that is no more.   At one point, the essay seems to be a family photo album, at another, it becomes an artist’s diary or journal, registering moments of emerging ideas, contamination by referential artists, the discovery of leftover materials, baskets, birdcages and backyard experiments of raw stages of his art, as well as work documents. What moves the artist to transit from photography to video production? Montsolid base for his creative process that interrogates the digital image and archiving.elli points to an accumulation of ideas, snapshots and images that overflow like something growing a long time in his own backyard, where he finds, his own context, and a a solid base for his creative process that interrogates the digital image and archiving.Keywords: Visual essay; creative process; backyard; digital photography; archiving.
Em Tempos de Reformas, a Alfabética
Authors: Noble André Winter
Published: May 2023

O ensaio visual apresenta a obra intitulada Reforma Alfabética que dedica um desenho para cada letra do alfabeto, de A à Z.  “A” deixa de ser associado à “abelha”; “B” deixa de ser associado à “bola”; “C” deixa de ser associado à “casa” e passa a, respectivamente, corresponder à “Apple”, “Benetton” e “Coca-Cola”. Como uma espécie de Mobral (Movimento Brasileiro de Alfabetização), resgatado de um contexto ditatorial brasileiro e, quase meio século depois trazido para um período de relações cada vez mais virtuais e dúbias ainda que semeadas em um campo “democrático”. Reforma Alfabética emerge como uma interrogação sobre a possibilidade de liberdade e, sobretudo uma crítica às instituições não apenas de ensino, como também de repressão.Palavras-chave: Alfabeta; reforma; contexto ditatorial brasileiro; liberdade. In Times of Reform, the AlphabeticalAbstract: The visual essay presents the work entitled Alphabetical Reform that dedicates a design for each letter of the alphabet, from A to Z. “A” is no longer associated with the “ant”; “B” is no longer associated with the “ball”; "C" is no longer associated with "cat" and corresponds, respectively, to "Apple", "Benetton" and "Coca-Cola". As a kind of Mobral (Brazilian Literacy Movement), rescued from a Brazilian dictatorial context and, almost half a century later, brought to a period of increasingly virtual and dubious relations, even though sown in a “democratic” field. Alphabetical Reform emerges as a way to question about the possibility of freedom and, above all, questioning the criticism aimed at institutions not only educational, but also that of repression.Keywords: Alphabet; remodeling; Brazilian dictatorial context; freedom.

Sex and Estrous Cycle Stage Shape Left-Right Asymmetry in Chronic Hippocampal Seizures in Mice

Lateralization of hippocampal function is indicated by varied outcomes of patients with neurologic disorders that selectively affect one hemisphere of this structure, such as temporal lobe epilepsy (TLE). The intrahippocampal kainic acid (IHKA) injection model of TLE allows for targeted damage to the left or right hippocampus, enabling systematic comparison of effects of left-right asymmetry on seizure and nonseizure outcomes. Although varying nonseizure phenotypic outcomes based on injection side in dorsal hippocampus were recently evaluated in this model, differences in chronic seizure patterns in left- (IHKA-L) versus right-injected (IHKA-R) IHKA animals have yet to be evaluated. Here, we assessed hippocampal seizure incidence in male and female IHKA-L and IHKA-R mice. Females displayed increased electrographic seizure activity compared with males at both two and four months postinjection. In addition, IHKA-L females showed higher seizure frequency than IHKA-R on diestrus and estrus at two months postinjection, but seizure duration and percent time in seizures were only higher in IHKA-L females on diestrus. These cycle stage-associated changes, however, did not persist to four months postinjection. Furthermore, this lateralized difference in seizure burden was not observed in males. These results indicate for the first time that the side of IHKA injection can shape chronic electrographic seizure burden. Overall, these results demonstrate a female-specific left-right asymmetry in hippocampal function can interact with estrous cycle stage to shape chronic seizures in mice with epilepsy, with implications for neural activity and behavior in both normal and disease states.

Thermal evaporation was used to prepare nickel (Ni) doped cadmium selenide thin films in different proportions (0, 1 and 3) wt.% on glass substrates at room temperature. According to XRD examination, all films possessed a polycrystalline hexagonal structure, with the (002) plane as the ideal orientation. According to AFM analysis, the average particle size decreases as the amount of doping increases, showing that the distribution of grains has become more uniform. The transmission and distortion ratios of the films were measured to learn more about their optical properties, which revealed that the (CdSe) films' transmittance decreased as the Ni films were doped, respectively. Additionally, it was discovered that all produced films had absorption coefficients larger than (α >104 𝑐𝑐𝑚𝑚- 1 ) and that the value of this coefficient rises with increasing doping. The films exhibited all direct optical energy gaps, according to the findings (CdSe). As the doping fraction decreased, the gap values decreased from 1.72 eV to 1.62 eV.
