RESUMO: Botulismo é causado pela ingestão de toxinas pré-fromadas produzidas por Clostridium botulinum. Este estudo descrevre um surto de botulismo tipo D em um rebanho bovino, com alta taxa de mortalidade (67%), devido ao consumo de silagem mal acondicionada. Os bovinos afetados apresentaram curso clínico hiperagudo e agudo de paralisia flácida progressiva. Cinco animais foram necropsiados e não foram visualizadas alterações macroscópicas e microscópicas. Embora a toxina não tenha sido detectada no alimento, a fonte mais provável de contaminação foi considerada a silagem armazenada inadequadamente. O diagnóstico de botulismo foi baseado nos achados clínicos, epidemiológicos e pela detecção da toxina botulínica no conteúdo intestinal de dois bovinos. O presente estudo enfatiza a morte de muitos bovinos por uma fonte incomum de toxina botulínica e a importância do manejo adequado no fornecimento de ração aos animais.

ABSTRACT: Botulism is a condition caused by the ingestion of pre-formed toxins produced by the bacterium Clostridium botulinum. This study described an outbreak of type D botulism with a high mortality rate (67%) in a cattle herd, caused by the consumption of fermented silage. The affected cattle presented with a hyperacute to acute clinical course with progressive flaccid paralysis. Five animals underwent necropsy with no significant macroscopic and microscopic alterations. A most probable source of contamination was deemed to be an inadequately stored silage; although, the toxin was not detected in the feed. The diagnosis of botulism was based on both clinical and epidemiological findings and the detection of botulinum toxin in the intestinal contents of two of the affected cattle. The present study emphasized the high number of fatally affected cattle, an unusual source of botulinum toxin and the importance of proper management of animal feed supply.

Resumo: Este artigo tem como objetivo compreender e comparar a animacidade construída gramaticalmente em orações no português brasileiro e no alemão tendo como base a Linguística Sistêmico-Funcional ( Halliday; Matthiessen 2014 ). Halliday, McIntosh e Strevens ( 1964 ) e Krzeszowski ( 1990 ) afirmam que todas as línguas podem ser contrastadas, à medida que possuam categorias teóricas e descritivas que possam estabelecer a equivalência entre elas. Para isso, um corpus comparável de artigos acadêmicos em português e alemão foi compilado ( Tognini-Bonelli 2010 ) e, posteriormente, a análise linguística da animacidade, mais especificamente, dos objetos semióticos, foi realizada em cada língua e contrastada. Os resultados mostram que o português e o alemão, à primeira vista, funcionam de forma semelhante; no entanto, a análise mais aprofundada revela que o alemão recorre a construções menos ativas para os objetos semióticos, ao passo que o português utiliza opções mais ativas em orações.

Abstract: This article proposes a contrastive study between Portuguese and German based on Systemic-Functional Linguistics ( Halliday; Matthiessen 2014 ). It aims to investigate how grammar construes animacy meanings in clauses of these two languages. Halliday, McIntosh, and Strevens ( 1964 ) and Krzeszowski ( 1990 ) point out that all languages can be compared since they have theoretical and descriptive categories that can establish equivalence between them. A comparable corpus was compiled using academic articles in Portuguese and German ( Tognini-Bonelli 2010 ). After this, the linguistic analysis of semiotic objects was performed in each language to enable the contrastive investigation. The results indicate that Portuguese and German have similar behavior at first sight, nonetheless the in-depth analysis uncovers that Portuguese uses semiotic objects in more active clauses than German.

RESUMO: A cultura da cenoura se destaca no cenário mundial por suas características nutricionais e importância econômica, aspecto que demanda o constante desenvolvimento de pesquisas visando maior produtividade. Assim, o objetivo deste trabalho foi propor um plano experimental, determinando as estimativas de tamanho de parcela, tamanho de amostra e número de repetições, com a finalidade de aumentar a precisão e confiabilidade dos resultados dos experimentos com a cultura da cenoura. Foram conduzidos seis ensaios de uniformidade, utilizando três cultivares em duas safras (Safra: 2019 e 2021). Cada planta foi considerada uma unidade experimental básica e em cada BEU foram medidas as variáveis altura da parte aérea, comprimento da raiz, massa fresca da parte aérea, massa fresca da raiz e diâmetro da raiz. O tamanho da parcela, da amostra e o número de repetições foram estimados pelo método da máxima curvatura do coeficiente de variação. Os resultados recomendam que para experimentos com a cultura da cenoura sejam utilizadas parcelas com doze plantas. Para amostragem de plantas de cenoura na parcela, devem ser utilizadas amostras de onze plantas no sentido da linha, considerando uma semi-amplitude do intervalo de confiança (D%) igual a 20% da média, com nível de confiança de 95%. Para uma diferença mínima significativa no teste de Tukey expressa em porcentagem da média de 50%, recomendam-se parcelas de doze plantas por fileira de cultivo, com oito repetições.

ABSTRACT: The carrotculture stands out on the world stage due to its nutritional characteristics and economic importance, an aspect that demands the constant development of research aiming greater productivity. Thus, this study proposed an experimental plan, determining the estimates of plot size, sample size, and number of repetitions, with the purpose of increasing the precision and reliability of the results of the experiments with the carrot crop. Six uniformity trials were conducted, using three cultivars in two growing seasons (Season: 2019 and 2021).Each plant was considered a basic experimental unit and in each BEU, the variables shoot height, root length, shoot fresh mass, root fresh mass, and root diameter were measured. The size of the plot, sample, and the number of repetitions was estimated by the method of maximum curvature of the coefficient of variation. The results recommend that for experiments with the carrot crop, plots with twelve plants should be used. For a sampling of carrot plants in the plot, samples of eleven plants must be used in the direction of the row, considering a semi-amplitude of the confidence interval (D%) equal to 20% of the mean, with a confidence level of 95%. For a minimum significant difference in the Tukey test expressed as a percentage of the 50% mean, plots of twelve plants per crop row, with eight replicates, are recommended.

RESUMO A batata-doce (Ipomoea batatas L.) possui grande variabilidade genética que contribui para maior produção e qualidades das raízes. Os agricultores de batata-doce do Oeste Paulista, Brasil, plantam durante as quatro estações e utilizam há duas décadas os mesmos genótipos. Desse modo, são necessárias pesquisas que visem avaliar novos genótipos e indicar os mais promissores. Portanto, objetiva-se identificar a adaptabilidade e estabilidade de genótipos de batata-doce em seis épocas de plantio: Setembro de 2019, Janeiro de 2020, Abril de 2020, Setembro de 2020, Outubro de 2020 e Dezembro de 2020 no Oeste Paulista, por meio da metodologia da regressão linear proposta por Eberhart & Russell (1966) e pelo método Centróide. Avaliou-se 17 genótipos, dois genótipos experimentais do Banco de Germoplasma da Universidade do Oeste Paulista e dois genótipos que são cultivados há mais de duas décadas pelos agricultores (Canadense e Ligeirinha Paulista). A partir dos resultados obtidos, os genótipos Canadense, IAPAR 69 e SCS 272 Marina, podem ser considerados como de ampla adaptação na região Oeste Paulista (ambientes favoráveis e desfavoráveis). Por sua vez, os genótipos UBD 01 e UBD 02 são indicados exclusivamente para ambientes desfavoráveis, enquanto que Ligeirinha Paulista, INIA Arapey, SCS 369 Águas Negras, BRS Rubissol, Brazlândia Branca, Brazlândia Roxa e BRS Amélia são indicados para ambientes favoráveis. batatadoce batata doce Ipomoea L.

ABSTRACT Sweet potato (Ipomoea batatas L.) have great genetic variability that contribute to higher production and root quality. Sweet potato farmers in the Western region of São Paulo state, Brazil, plant during the four seasons and have used the same genotypes for two decades. Thus, research is needed to evaluate new genotypes and indicate the most promising ones. Therefore, the objective of this study was to identify the adaptability and stability of sweet potato genotypes in six planting seasons: September 2019, January 2020, April 2020, September 2020, October 2020, and December 2020 in Western São Paulo using the linear regression methodology proposed by Eberhart & Russell (1966) and the centroid method. We evaluated 17 genotypes, two experimental genotypes from the germplasm bank of the University of Western São Paulo and two genotypes that have been cultivated for more than two decades by farmers (Canadense and Ligeirinha Paulista). The results show that Canadense, IAPAR 69, and SCS 272 Marina can be considered widely adapted in the Western region of São Paulo (favorable and unfavorable environments). In turn, the genotypes UBD 01 and UBD 02 are indicated exclusively for unfavorable environments, while Ligeirinha Paulista, INIA Arapey, SCS 369 Águas Negras, BRS Rubissol, Brazlândia Branca, Brazlândia Roxa, and BRS Amélia are indicated for favorable environments.

Brazil has abundant agro-industrial residues, such as cassava peel, opening the opportunity to produce high-added value chemicals by catalytic fast pyrolysis, in which the desirable products can be tailored. Aiming to provide an application of cassava peel residues, as well as to produce high-value BTEX (benzene, toluene, ethylbenzene and xylenes), beta zeolite-supported nickel (3 and 5 wt.%) catalysts were evaluated in fast pyrolysis. Without any catalyst, large amounts of high-value oxygenated compounds (ketones, carboxylic acid and phenolics) were produced while no BTEX was formed. This was related to the higher amount of cellulose and hemicellulose, as compared to lignin in cassava peel. However, over beta zeolite, these oxygenated compounds go on oligomerization, decarboxylation and decarbonylation producing aromatics (BTEX and polyaromatics), indicating a new reaction route provided by the catalyst. The amount of BTEX and other aromatics increased even more over zeolite-supported nickel, suppressing polyaromatics formation. This is related to the increased strength and amount of acidity of Lewis sites. The most selective catalyst (3% Ni) produces 67% of BTEX and no polyaromatics. Cassava peel and beta zeolite-supported nickel thus proved to be a promising combination to produce BTEX generating a new application of cassava peel residues. agroindustrial agro industrial residues highadded high added pyrolysis tailored highvalue benzene, benzene (benzene toluene xylenes, xylenes , xylenes) zeolitesupported zeolite supported 3 ( wt.% wt ketones, ketones (ketones phenolics formed hemicellulose However oligomerization polyaromatics, polyaromatics) formation sites 3% Ni 67 wt. 6

ABSTRACT Objective: Intrauterine environment can induce fetal metabolic programming that predisposes to adiposity-related chronic diseases in its lifespan. We examined the associations of parental nutritional status and gestational weight gain with offspring body composition in early adulthood. Materials and methods: This is cross-sectional analysis of female participants of the NutriHS who were submitted to questionnaires, clinical examinations and body composition assessed by DXA. Association of pre-conception parental BMI and maternal gestational weight gain (exposures) with body composition measurements (outcomes) were analyzed using multiple linear models adjusted for Directed Acyclic Graphs-based covariables (maternal and paternal educational level, maternal age, and tobacco, alcohol and/or drugs use). The sample included 124 women (median 28 (24-31) years) with a mean BMI of 25.4 ± 4.7 kg/m2. Results: No association between previous paternal BMI and offspring’s body composition was detected. In the fully adjusted linear regression model, maternal BMI was associated with offspring’s total lean mass (β = 0.66, p = 0.001), appendicular skeletal muscle mass index (ASMI) (β = 0.11, p = 0.003) and fat mass index (FMI) (β = 0.03, p = 0.039). Gestational weight gain was associated with increased offspring’s BMI (OR 1.12 [95% CI 1.02-1.20], p = 0.01). The linear regression model adjusted for maternal age and maternal and paternal education levels showed associations of gestational weight gain with offspring’s ASMI (β = 0.42, p = 0.046), FMI (β = 0.22, p = 0.005) and android-to-gynoid fat ratio (β = 0.09, p = 0.035). Conclusion: Our findings suggest that preconception maternal BMI could influence lean mass and general adiposity of young adult female offspring and that gestational weight gain could be useful for predicting centrally distributed adiposity.

The composition of human milk (HM) includes changes under the influence of factors such as genetics, stage of lactation, time of day, and even breastfeeding time. However, the authors are not aware of studies that evaluated the influence of breastfeeding time on fatty acid composition and cytokine. Thus, the objective of this study was to evaluate the influence of breastfeeding time (previous, intermediate, posterior milk) on kilocalorie concentration, fatty acid (FA) composition, and concentration of the cytokines interleukin-10 (IL-10), interferon factors for necrotic tumor (TNF-α) in HM colostrum. The results showed that the concentration of kilocalories was higher in posterior milk than in the previous, the composition of the main fatty acids found in the samples was influenced by the breastfeeding time, and the concentration of IL-10 and TNF-α was influenced in all samples with exception to mother 2. The principal component analysis explained 71% of the variances in the results. Thus, we concluded that the breastfeeding time is a factor that influences the concentration of kilocalories, and if it is necessary to use a more caloric milk, it is recommended to use the posterior milk; the FAs composition and the evaluated cytokines were also influenced by the breastfeeding time.

Abstract Historically, phenol/croton oil deep chemical peeling has been very effective and has generated excellent results compared to other formulas used in dermatological clinics. However, it can cause serious side effects in patients sensitive to phenol. Therefore, this study aimed to develop a liquid crystalline structure containing croton oil (without phenol) as well as to evaluate the physical characteristics and cytotoxicity of this new system. Rational proportions of the croton oil, purified water, and polyethylene glycol hexadecyl ether were designed through a partial phase diagram to obtain 26 formulations. After macroscopic analysis and polarized light microscopy evaluation, formulations with lamellar liquid crystalline phase (4 samples) were identified and chosen to determine pH, size, polydispersion index (PDI), zeta potential, and rheological behavior. After 48 hours, three samples presented phase separation. Formulation 8 remained stable, but hydroxyethyl cellulose (HEC, 0.5%, w/w) was added to the aqueous phase, to prevent coalescence. Sample 8A exhibited a pH compatible with the skin, nanometric size, narrow PDI, negative zeta potential, and stability throughout the study period. The addition of HEC improved the organization of the system, making the formulation more stable. The oil, fractions of the oil, and the sample exhibited increasing cytotoxicity, respectively. This result could be attributed to the fractionation process of the vegetal matrix, and the surfactant present in the formulation increased the cell membrane permeability. The proposed approach successfully achieved a physically stable liquid crystal system containing croton oil.

ABSTRACT Amaranthus hybridus is a C4 broadleaf species widely spread across Brazilian agricultural territory. Recently, several herbicide resistance reports have been documented in southern Brazil, including the reports for enolpyruvilshikymate-3-phosphate (EPSPS)- and acetolactate-synthase (ALS)- inhibitors. The objective of this study was to confirm the existence of an ALS resistant (R) A. hybridus population from Paraná state. Dose-response experiments were conducted with R and a known susceptible (S) population with herbicides from three different chemical groups of ALS inhibitors. Biomass relative to untreated control was quantified and GR50 (dose for 50% of biomass reduction), GR90 (dose for 90% of biomass reduction) and resistant index (RI) were calculated based on non-linear regression analysis. The R population was 6.9-fold resistant to chlorimuron-ethyl and 6.5-fold resistant to metsulfuron-ethyl (sulfonylureas - SUL). Additionally, the recommended rates from each herbicide was not sufficient to reach 90% control to R based on GR90 parameter estimation. There was no resistance to imazethapyr (imidazolinone - IMI) and cloransulan-methyl (triazolopyrimidine - TRI) due to the low doses of GR90 and non-significant RIs. The R A. hybridus population investigated was resistant to ALS inhibitors chlorimuron-ethyl and metsulfuron-ethyl (SUL), but susceptible to IMI and TRI herbicides.

Abstract Background: The implementation of Telecardiology in primary care in the city of Porto Alegre, Brazil, is a viable and promising strategy. It would decrease the distance between patient and specialized professional services by reducing unnecessary referrals and improving the quality of primary care and satisfaction of patients and health professionals. Objective: To implement a Telecardiology service and assess user satisfaction using the CARDIOSATIS scale. Methods: This was a pilot study developed by a partnership between the Institute of Cardiology and the Telehealth Center of Rio Grande do Sul. The study was carried out at Eri Flores-Vila Vargas health center in the city of Porto Alegre, from May to October 2019, and included 21 patients attending the health center. The descriptive analysis of data was performed using the SPSS program (Statistical Package for the Sciences) version 23. Data normality was checked using the Kolmogorov-Smirnov test. Statistical significance was set at 10%. Results: Mean age of participants was 43.8 ± 16.1 years. The most common risk factors in the sample were physical inactivity (81%) and smoking (43%). Most patients had normal electrocardiogram (ECG) readings. The time elapsed from the performance of the ECG test, transmission of the ECG traces to Telehealth, and return of the final ECG report to the health center was 0-7 days. The CARDIOSATIS scale revealed a high prevalence of “very satisfied” users for the general satisfaction domain, and only 14.3% of patients were dissatisfied with their health. Conclusions: Telecardiology reduced the distance between patient and the specialized professional, with a high level of patient and health professional satisfaction. Our study can serve as a basis for the implementation of a telecardiology network in the city of Porto Alegre in the future.

Resumo O objetivo deste trabalho foi determinar o tamanho ótimo de parcela e o número de repetições para avaliação da massa de matéria fresca de azevém semeado em filas. Setenta ensaios de uniformidade foram realizados com azevém 'Barjumbo', em 16 unidades experimentais básicas (UEBs) de 0, 51 m 2 cada uma. A massa de matéria fresca do azevém nas UEBs de 18, 18, 6, 6 e 22 ensaios de uniformidade foi determinada, respectivamente, aos 130, 131, 133, 134 e 137 dias após a semeadura. O tamanho ótimo de parcela foi determinado pelo método da máxima curvatura do coeficiente de variação. O número de repetições foi determinado em cenários formados por combinações de número de tratamentos e de diferenças entre médias a serem detectadas como significativas pelo teste de Tukey, a 5% de probabilidade. O tamanho ótimo de parcela oscilou de 1,73 a 3,18 m2, e o coeficiente de variação no tamanho ótimo de parcela de 7,58 a 13,96%. O número de repetições oscilou de 3,95 (~4) a 32,27 (~33), conforme o delineamento, o número de tratamentos e a diferença mínima adotada. O tamanho ótimo de parcela é de 2,29 m2 e, em experimentos com até 50 tratamentos, são necessárias oito repetições para identificar como significativas as diferenças entre médias de tratamentos de 20,24%.

Abstract The objective of this work was to determine the optimal plot size and the number of replicates for the evaluation of the fresh weight of ryegrass sowed in rows. Seventy uniformity trials were performed with 'Barjumbo' ryegrass, in 16 basic experimental units (BEUs) of 0.51 m2 each. The fresh weight of ryegrass in the BEUs of 18, 18, 6, 6, and 22 uniformity trials was determined, respectively, at 130, 131, 133, 134, and 137 days after sowing. The optimal plot size was determined through the method of the maximum curvature of the coefficient of variation. The number of replicates was determined in scenarios formed by combinations of treatments and differences between means to be detected as significant by Tukey’s test, at 5% probabilit y. The optimal plot size ranged from 1.73 to 3.18 m2, and the variation coefficient in the optimal plot size from 7.58 to 13.96%. The number of replicates varied from 3.95 (~4) to 32.27 (~33), depending on the experimental design, the number of treatments, and the adopted minimum difference. The optimal plot size is 2.29 m2, and, in experiments with up to 50 treatments, eight replicates are required to identify as significant the differences between treatment means of 20.24%.

RESUMO: As divergências no temperamento dependem da reação dos animais às pessoas e à diferentes situações sociais e ambientais. Contudo, pouco se sabe acerca da influência de alterações no ambiente pastoril sobre o temperamento dos bovinos. Com isso, a hipótese de trabalho é de que o temperamento dos animais pode ser alterado se mantidos em sistemas pastoris arborizados. Para tanto, objetivou-se avaliar o efeito do componente arbóreo em ambiente pastoril sobre o temperamento de bovinos em pastejo em sistemas integrados de produção agropecuária. Foram avaliados 32 novilhos da raça Angus alocados em dois sistemas pecuária (PEC) e pecuária-floresta (PF) durante o período de dezembro de 2019 a fevereiro de 2020, no qual foi mensurado: o escore de reatividade dos animais; a velocidade de fuga e o número de vocalizações. O modelo estatístico utilizado considerou como efeito fixo de tratamentos e períodos e efeitos aleatórios dos animais, utilizando o procedimento MIXED, as médias foram comparadas pelo recurso lsmeans. A velocidade de saída e número de vocalizações foram similares entre os sistemas de produção. O escore de reatividade foi menor para os animais mantidos no sistema PF quando comparados aos do tratamento PEC. O sistema PF interfere positivamente no temperamento animal em relação ao sistema de produção PEC, observado pelo menor escore de reatividade nos animais mantidos neste sistema. Contudo, o estudo sobre a influência da integração de sistemas sobre o temperamento animal exige mais pesquisas para revelar o potencial deste modelo de produção sobre o comportamento animal.

ABSTRACT: Temperament often depends on the animals’ reaction to people, social and environmental conditions. However, little is known about the influence of changes in the pasture environment on cattle temperament. Thus, this study was designed to evaluate if an animals’ temperament changes in response to being kept in a silvopastoral system. This study evaluated the effect of the tree components in a pasture environment on the temperament of any grazing cattle in integrated crop-livestock systems. A total of thirty-two Angus steers were allocated to either a livestock (L) or livestock-forest (LF) system and observed from December 2019 to February 2020. Each animal was evaluated for their reactivity score, flight speed, and number of vocalizations. The statistical model established that the animals were random effects and that the treatments and periods were fixed effects using the MIXED procedure, and the means were compared using LSMeans. The flight speed and number of vocalizations were similar in both production systems, while the reactivity score was lower for animals kept in the LF system when compared to those in the L system. This suggested that the LF system interferes positively with the animal’s temperament in relation to the L production system. However, additional research is needed to understand the influence of the production system on animal temperament.

RESUMO Tendo por finalidade identificar princípios de organização do léxico segundo a Abordagem sistêmico-funcional (HALLIDAY; MCINTOSH ; STREVENS, 1964; MARTIN, 1992; HALLIDAY, 2002; FIGUEREDO, 2011), subsidiada por metodologia da Linguística de Corpus, o presente artigo explica dois processos de transformação pelos quais o léxico se integra aos sistemas da língua, quando relacionado ao eixo paradigmático nos estratos gramatical e do registro por meio da co-extensividade. Tem-se aqui como motivação o fato de que as concepções acerca do léxico modular – modelado como preenchimento de estruturas gramaticais – ou léxico contíguo – modelado como a gramática delicada – necessitam de maior elaboração quanto aos processos internos relativos à dimensão do léxico, bem como às relações do léxico, para além da gramática, com o discurso e o contexto. Neste artigo, especificamente, investigam-se os processos de transformação da gramática e do registro, incluindo principalmente o desenvolvimento de protocolos para análise de processos internos do léxico, assim como a caracterização de como itens lexicais são demandados por um determinado registro.

ABSTRACT This paper aims at identifying principles of lexis organization under a Functional Approach HALLIDAY; MCINTOSH; STREVENS, 1964 MARTIN, 1992 HALLIDAY, 2002 FIGUEREDO, 2011 based on corpus evidence. Problems with the modular and delicacy approaches to lexis – i.e., lexis as filling for grammatical structures or most delicate grammar – motivate the paper as they need further elaboration to describe the internal processes of lexis as a dimension of language, as well as lexis relations to discourse and context. The paper goes on to explain transformation processes integrating lexis and language systems, as lexis is co-extensive to the system in the grammar and register strata. Transformation processes of grammar and register are investigated and lead to the development of protocols of processes internal to lexis. Results show how the protocols can reliably account for the generation of lexical items to a given register. This, in turn, sheds light on lexis internal organization.

Resumo Este artigo busca pensar a potência das imagens enquanto campo de experimentação e de criação em educação, junto às filosofias da diferença, aos movimentos transversais acionados por uma estratégia investigativa cartográfica e à problemática: o que podem as imagens em meio ao traçado de planos de imanência e de composição? Este trabalho problematiza as experiências educativas e investigativas que as autoras têm vivenciado junto à graduação e à pós-graduação, mobilizando uma delas especificamente para operar enquanto materialidade deste texto. Tal experimentação, produzida em uma aula, com uma turma de Licenciatura em Artes Visuais de uma universidade do Sul do Brasil, é operada de modo a explicitar algumas maquinarias que movimentaram o grupo nessa produção, assim como outras surgidas também durante a escrita do artigo por três pares de mãos. Sem a intenção de ilustrar e prescrever modos de relação com as imagens, e tomando a imagem por sua potência plural, desprendida de um sentido representativo e de uma única forma de relação, busca-se produzir aberturas para (im)possíveis vias de criação com as imagens em educação, deixando, também, alguns fios soltos, enquanto isca para outras possibilidades que possam ainda funcionar com elas. Fios que dizem aquilo que não foi possível capturar em imagens e escritas, névoas que se ergueram na composição produzida e que seguem, portanto, em potência, à espera de outros encontros.

Abstract The present article aims at thinking of the potential of images as a creation and experimentation field in education. Along with the difference philosophies, transversal movements triggered by a cartographic investigative strategy and the problematic: what can images do in the midst of tracing planes of immanence and composition? The present study problematizes the investigative and educational experiences the authors have encountered during the undergraduate and graduation levels, mobilizing one of them specifically to operate as the materiality of the present text. This experimentation, produced during a class, with a group of students in a teaching degree in visual arts in a university in the south of Brazil, is operated in a way of making explicit some machinery that moved the group during this production, as well as others that also emerged during the writing of this article by three pairs of hands. Without the intention of illustrating and prescribing ways of relating to the images, and taking the image by its plural potentiality, detached from a representative meaning and a single form of relation, we aim at producing openings for (im)possible ways of creation with images in education, and, also, leaving loose threads, as bait for other possibilities that might still work with them. These threads express what was not possible to capture in images and writing, mists that rose in the composition produced and that continue, therefore, in potential, waiting for other encounters.
