El proceso de educación inclusiva en Colombia ha seguido orientaciones que los entes internacionales en diferentes momentos han establecido, se ha planteado que esta debe estar dirigida a todos los participantes permitiendo la diversidad y desarrollándose en equidad, para lo cual, los docentes son claves, al ser los encargados directos del contacto con los estudiantes, por ello la formación de los mismos es de gran importancia para alcanzar esta meta. El Ministerio de Educación Nacional (MEN) afirma que una de las formas de mejorar la inclusión es por medio del Diseño Universal para el Aprendizaje (DUA) por ello es importante que los maestros conozcan sobre el mismo. Debido a lo anterior, el objetivo este trabajo fue analizar las percepciones de los estudiantes de la licenciatura en el área de ciencias naturales sobre la educación inclusiva y analizar la evaluación que los estudiantes de licenciatura en ciencias naturales realizaron a una guía de orientaciones sobre el diseño universal para el aprendizaje (DUA) en el área. La investigación se desarrolló en tres universidades de Colombia, fue de tipo descriptivo y tuvo dos fases, una primera que recogió por medio de un cuestionario cerrado las percepciones de treinta participantes sobre el DUA y la educación inclusiva, el análisis de los datos fue cuantitativo -a través de gráficas que permitían ver la relación numérica- y cualitativo por medio de la selección de categorías que permiten evidenciar la temática central de las respuestas. Con los resultados de la primera fase, se elaboró una guía de orientación sobre la educación inclusiva y el DUA que fue analizada por cinco participantes que decidieron continuar en la segunda fase, esta se dio por medio de una entrevista semiestructurada en la que se pedía las opiniones sobre guía; del proceso se hizo la transcripción y el análisis de contenido para encontrar las clases temáticas que agruparon la información aportada. Como resultados de la primera fase se encontró que los participantes indican un bajo conocimiento en los procesos, temas y políticas relacionadas con la educación inclusiva, al igual que en lo relacionado al DUA y las posibilidades que este tiene en las ciencias naturales, afirmando no saber cómo aplicarlo dentro del área; de la segunda fase, se concluyó que el área puede ser visualizada desde el desarrollo de las competencias por medio del DUA y este puede ser una opción para que se den los procesos de educación inclusiva, sin embargo los participantes indican que necesitan mejoras en los programas de formación de maestros y un apoyo continuo de los equipos interdisciplinarios de las instituciones, para tener una formación continua y poder desarrollar propuestas que permitan mejorar los ambiente en las instituciones educativas. De esta manera se concluye que la guía permitió mejorar la visión sobre el DUA y la forma de aplicarlo en las ciencias naturales para que puedan darse los procesos de educación inclusiva en los futuros ambientes de aprendizaje y se pueda enseñar pensando desde la diversidad de una forma más universal con prácticas innovadoras.

Trapdoor tests have been commonly used in laboratory environments to simulate the behavior of piled embankments. Although this set can be simply represented by a system of trapdoors, the complexity imposed by the interaction between the granular layer, soft soil and the piles demands further investigations. In addition, limited studies have been carried out to investigate the deformation patterns and internal mechanisms of load transfer platforms reinforced with geosynthetics. This type of investigation is intrinsically complex in view of the interaction between the different components. Therefore, complete understanding depends on both qualitative and quantitative analyses, considering the performance of all components. This study proposes the use of a layered transparent system to evaluate the behavior of load transfer platforms reinforced with geosynthetic through experimentation by physical models. This approach involved the use of two families of transparent soils: fused quartz and Laponite RD. The layered models of transparent soils proved to consistently simulate the behavior of piled embankments. The Digital Image Correlation (DIC) technique was used to monitor the displacement field of the layered systems. The physical models’ responses produced deformations that followed the triangular expanding pattern. Furthermore, the deflection pattern of load transfer platforms was found to behave similarly to continuous concrete beams subjected to bending. The presence of geosynthetic reinforcement reduced, in general, the displacements and deformations of the models. From the point of view of load transfer, the use of geosynthetics reduces the effect of soil arching only when they are located within the tensile zone of the granular layer.

The refractory ceramic materials used in thermal insulation can be classified into three large groups: insulating bricks and concrete, fiber-based refractories and macroporous ceramics. Such macroporous ceramics, commonly present high porosity, controlled permeability, high chemical and dimensional stability at high temperatures, low density, and have aroused technological interest. Opacifying agents (e.g. SiC, TiO2, ZrSiO4) are usually added to macroporous refractory ceramics with the aim of increasing the absorption of infrared radiation and reducing the thermal conductivity in order to reduce the heat transfer by radiation and the conductivity total thermal at high temperatures. However, the introduction of these additives can generate side effects to the material properties. Thus, the present work aimed to obtain a better understanding of the manufacture of macroporous ceramics by the direct foaming processing route, as well as to evaluate the properties of macroporous ceramics based on alumina regarding the addition of opacifying agents ZnO, TiO2, Nb2O5 and the combination between them, being ZnO-TiO2 (equimolar) in concentrations of up to 2.8 mol%. For this, the different compositions were characterized according to their post-burning linear variation, total porosity, mechanical resistance, apparent density, quantitative mineralogical composition, refractoriness under load and microstructural analysis from the scanning electron microscope.

Performance measurement systems (PMS) are fundamental components of performance management, particularly in light of the rapid transformations occurring within organizations' internal and external environments. As a result, there is a growing need for dynamic and resilient PMS capable of adapting to these changes. Industry 4.0 (I4.0) technologies, in particular, hold significant potential for enhancing PMS. However, the implementation of these technologies within PMS is a complex process and is susceptible to various barriers. Consequently, it is essential to identify the enablers that facilitate this implementation process to effectively adapt PMS in the context of I4.0. Therefore, this thesis aims to analyze the most relevant enablers in the implementation process of I4.0 technologies in PMS, applying the Fuzzy DEMATEL method. For this purpose, a scientific mapping and systematic literature review were initially carried out to comprehensively understand the research field and identify the primary studies and contributions related to I4.0 technologies in PMS, as well as the key enablers involved in their implementation process. Subsequently, the Fuzzy DEMATEL method was applied to select and rank the most significant enablers based on expert opinion. The findings unfold that I4.0 technologies have a positive impact on PMS, specifically in terms of enhancing strategic management decisions. By leveraging I4.0 technologies such as cyber-physical systems, internet of things, big data analytics, simulation, and virtualization techniques within PMS, organizations can foster intelligent, decentralized, autonomous, and real-time decision-making in a broader network involving all stakeholders. The application of the Fuzzy DEMATEL method pointed out the most significant enablers for the implementation of I4.0 technologies in PMS and prioritized as follows: "Accessibility and data integration," "Data quality," and "Clarity on the economic benefits of implementing I4.0 technologies in PMS"; "Top management support"; "Adequate digital infrastructure"; "Qualified employees" and "Continuous training of employees"; and "Creation of government policies and incentives". In conclusion, this thesis contributes to understanding of the enablers required for the effective adoption of I4.0 technologies in PMS.

The present study aimed to investigate how the professional training of students with ASD at a Federal Institute of Bahia has been consolidating, using information obtained from the students themselves, as well as from their teachers, support professionals and family members. The specific objectives of the study were: i) to analyze the perspectives of teachers, support professionals, students and family members regarding the insertion of students with ASD in the common spaces of regular teaching of secondary professional education and ii) to investigate the conditions offered in this training for the inclusion and permanence of students with ASD. The study was carried out on one of the twenty-two campuses of the Federal Institute of Bahia and involved 18 participants, 03 students with ASD, 10 teachers who teach classes for these students, 02 school support professionals and 03 family members, this study guided by an exploratory descriptive method. The study took place in the following stages: data collection, which took place through a script of semi-structured interviews with all participants, with questions prepared according to four categories: 1) School inclusion; 2) Pedagogical practices adopted by teachers; 3) Prospects for the future of students and their families regarding professional training; 4) Relationships between peers (execution of group activities and friendship bonds) carried out through Google Meet and in the study on formative and acting experiences in the service of students with ASD. Data analysis was based on the technique of content analysis using the Atlas.Ti software in the organization and categorization of data and with the theoretical support of the literature on special education and ASD. The survey results revealed important information about the positive aspects and points to be improved in the experiences of students with ASD in high school professional education. The crucial importance of the teaching staff and support professionals in the school inclusion of these students was highlighted. Adequate training, which includes the implementation of a functional curriculum and the strengthening of the relationship between teacher and student, proved to be essential to facilitate the teaching and learning process. In addition, families play an essential role in the academic trajectory, fighting for the rights and access to education for their children with ASD. It is necessary to provide more assertive guidance to students with ASD regarding their professional choice, as the results indicated difficulties in understanding this process and future prospects after completing the course.

It is well known that several researches related to the development of renewable and alternative energy sources are currently in course. However, with the continuous increase on energy demand around the world, it is still necessary to explore other energy resources, mainly on oil and gas field, available in extremely aggressive environments such as the deep-sea water levels. In order to reach such natural reservoirs and extract its resources, new classes of nickel-based superalloys were developed, offering better combination of properties to handle the application in these aggressive environments with higher-pressure levels, avoiding equipment failure due to Hydrogen embrittlement and stress corrosion cracking. Particularly, the alloy UNS N09925 presents superior mechanical resistance when compared to other similar alloys and keeps its excellent corrosion resistance, which allows us to use it for larger dimension parts and component manufacturing, such as tubular systems, valves, hangers, shafts, and fasteners. This characteristic is related to its primary strengthening mechanism called precipitation hardening. This mechanism is related to the precipitation of γ′ − Ni3(Al, Ti) in the austenitic matrix of the alloy, which contributes to restrict dislocation movement. However, it is well known that deleterious phases such as sigma (σ) and eta (η) also can form during the material aging cycle. Therefore, it is of great importance to improve our knowledge about this heat treatment of the alloy UNS N09925. With such knowledge, it becomes possible to choose adequate aging temperatures and time parameters to optimize the heat treatment cycle, commonly performed in two steps, in order to maximize the alloy aging potential. As a result, one can expect an increase in the mechanical resistance of the alloy and reduced precipitation of unwanted deleterious phases in the austenitic matrix, avoiding loss of toughness, ductility and corrosion resistance.

Automated Guided Vehicles (AGVs) have been used in manufacturing environments for over five decades. The technologies applied to AGVs advanced along with electronics and computing technology progress, which increased vehicles' sensory and processing capacity. Currently, such vehicles are applied to internal logistics systems and industries' shop floor, but they are also used in different environments. As a guided system, position control is essential for the system. A good control system performance allows a safe application of AGV in the environment and impacts the performance of a production line, for example. Many solutions have been proposed in the literature. However, there are still factors that still need to be considered. Two of these factors are vehicle dynamics under different load conditions and the application of multiple measurements to reduce measurement uncertainties and improve controller performance. Since AGV is a complex system, several system variables can be measured, and the problem can be treated as a multivariable problem. In this condition, using multiple sensors allied with the controller's adaptive capacity following the load condition is expected to contribute positively to the control system's performance and increase its accuracy. Thus, this work aims to present the proposal of a cascaded and multi-sensors adaptive fuzzy controller for the AGVs position control problem. The proposed system aims to increase the accuracy of the AGV position.

The inclusion of Special Education Target Public Students (PAEE) in the common school provokes reflections about the training and performance of teachers of the different degrees. Thus, we raise the following question: Is the area of Special Education being contemplated in the political-pedagogical project and in the curricular organization of the Degree courses in Geography of the Public Institutions of Higher Education (IES) of the state of Paraná? Thus, the general objective was to analyze the training of teachers in undergraduate courses in geography with regard to the propositions of special education in the inclusive perspective. This research has a qualitative approach of documentary character. A total of 15 courses were investigated, nine from state and two federal institutions, distributed throughout the territory of Paraná. The following steps were followed: selection of documents, exploratory reading of the files and application of the documentary analysis script. The collected data were organized and analyzed using the technique of content analysis with the pre- and post-defined categories. The data showed that the teaching model presented by most of the courses is based on the DCNs, in which we identified a teacher capable of working considering the diversity in teaching. Despite this, we note that the textual structure of PPPs presents little or no discussion in relation to the contents of special education. The data of the curricular components showed that the minimum of disciplines and contents required by law on special education is offered, which conflicts considering the formative model that the courses propose to form. We also perceive the rupture of the specific knowledge of geography with the pedagogical knowledge that underlies the formation in licensure, which may not contribute to a teacher training adequate to the context of an accessible education. This demonstrates that the absence of didactic-pedagogical in undergraduate courses will cause special education to remain segregated in the formative curriculum.

Lignocellulosic biomass is the second largest source of carbon available on the planet. However, the viability of biorefineries depends on overcoming challenges such as the search for microorganisms capable of converting pentoses into 2G ethanol and high added value products. Thus, the present work aimed to evaluate the production of 2G ethanol and xylitol by the yeast Meyerozyma guilliermondii (CCT7783) from residues from the production of pencils and sugarcane straw. The yeast M. guilliermondii was adapted on xylose and the exact results that the specific growth rate was 75% higher for spontaneously adapted strains. In the second phase of the study, the adapted strains were applied in a study of the effect of fermentation conditions and the required results that high hypoxic conditions and high rotations lead to a reduction in biomass production and an increase in xylitol production. Ethanol production was higher with increasing concentration of pentoses and inoculum. In the fermentation of the hydrolysates approximately 50% of the sugars were converted into 2G ethanol and 7% into xylitol for both considered hydrolysates, having a controlled effect on the fermentation time for the hydrolysates from pencil residues. The yeast M. guilliermondii has potential for application in biorefinery processes and optimized conditions can lead to a targeted biosynthesis with higher yields.

The literature related to palliative care and indigenous populations generally reports the experiences of first peoples from the northern hemisphere, addressing topics such as dying outside their lands, traditional care, ceremonies, and rituals after death. This material does not always focus on occupations that refer to the affirmation of life or the preparation for death in indigenous communities in Latin America, especially in Colombia. Thus, this study aims to describe the occupational processes at the end of life of Colombian indigenous communities in the Sierra Nevada de Santa Marta. It seeks to reveal the appreciation of non-Eurocentric palliative care, in the construction of individual and collective meanings of the Kankuamo and Arhuaco peoples around the processes of death, dying and mourning. Under a decolonial positionality, community contemplation, alternative conversation and configurative reflection are integrated as guiding actions that accompany native science, using Tejido/Yarning, as a resource based on respect, freedom, reciprocity, specificity, inclusion and cultural safety. Through seven purposes: therapeutic, social, family, intercultural, investigative, collaborative and relational, feelings were woven with the Mayoras, spiritual authorities (Mamus, Akumama), bereaved families and indigenous children. Themes related to care in the face of the processes of death were intertwined; the cosmological origin of death and its payments; postmortem ancestral ceremonies such as "seeding" and "eysa/mortuoria"; the reframing of pain in the face of loss; ways of intercultural learning about death and dying; as well as Mother Earth, spirituality and religion, reflecting on the meanings of their collective, ancestral and traditional memories toward the end of life. Thus, the study can be a contribution to history and intercultural dialogues, to broaden the understanding of health professionals, notably occupational therapists, about the culturally safe occupational dimension of death, dying and mourning based on the feelings and actions of indigenous communities.

This dissertation presents a study on Alfonsina Storni's female columns published in the Buenos Aires press between 1919 and 1921. In the first column, Feminidades/ Vida Femenina, published in La Nota magazine, the poet Alfonsina Storni signed. In the second, Bocetos Femeninos, published in the newspaper La Nación, the columnist Tao Lao signed. From a critical and multiple theoretical perspective that considers gender relations and criticism as the main thread, this study seeks to understand Alfonsina Storni's writing in female columns, a marketing space targeted at wives, mothers, and consumers: how she wrote and what she put at stake in such specific spaces, what and how Alfonsina produced within and even with these limitations. Unlike the purely negative view of the ideological, sexist, and marketing limitations of female columns, this study reads the limits as a possibility for other inscriptions. Therefore, it investigates first the general and particular context of Alfonsina Storni, the representation and space of the woman writer in Argentine society at the beginning of the twentieth century, the specific literary trajectory, and the location and construction of female columns in the Buenos Aires press. In the second chapter, the study focuses on La Nota magazine and the female columns published by Alfonsina Storni, investigating the strategies of representation of being a woman in modernity. In the third, the study explores Alfonsina Storni's transition to La Nación newspaper, where the signature of Tao Lao is seen, and the dilution of gender stereotypes. Reflecting on the construction of the name and gender performance, the study aims to understand the literary and discursive work in the construction of Tao Lao: he is not just a mask, but a persona with a voice (specifically of a columnist) created for the female section.

Brazil has a megadiversity that is still poorly known, particularly regarding wasps of the Braconidae (Hymenoptera) family. Even at a regional level, there is a scarcity of studies presenting inventories of genera or species, although such information is essential for a wise management of biodiversity. In this scenario, the present study aimed to identify Braconidae at the genus level through two approaches: molecular characterization (COI gene) and morphological characterization. For this purpose, Malaise traps were used during the first half of September 2021 in contiguous areas of semideciduous mesophytic forest, reforestation, silvopastoral system, and gallery forest, located in the municipality of São Carlos, São Paulo State. A total of 339 individuals was collected, and through morphological characterization, 47 genera were identified, distributed among 19 subfamilies. Additionally, the following characteristic measurements were calculated for the Braconidae community in the studied localities: dominance, abundance, and frequency indices, as well as the richness, diversity, and evenness of the collected genera. Molecular characterization enabled the identification of 49 specimens distributed in seven genera, five of which belonged to the subfamily Microgastrinae. Although both identification strategies have the same purpose and can be used together, it is concluded that the application of one or the other may be more convenient given the presented context. Subfamilies and genera better represented in COI reference sequence libraries tend to have a higher success rate in molecular identification, while other groups can be more easily identified by morphological characters. As a contribution to future research involving Braconidae diversity, new COI sequences were deposited in an international reference library (BOLD Systems) and a new species for Brazil was described.

The aim of this study is to analyze, together with a deaf student who has completed high school, their perceptions regarding accessibility in this educational stage. In light of the bilingual educational proposals outlined in Decree 5,626/2005 and Law 14,191/2021, and with the presence of sign language interpreters and translators, it is expected that schools are prepared to adequately accommodate these students, particularly in high school, which aims to prepare students for their professional life and university entrance. However, educators do not always possess the necessary preparation for this, which can hinder accessibility and knowledge acquisition, as well as impact the future choices of deaf students. Thus, this is qualitative research utilizing semi-structured online interviews as the data collection instrument. The participant is a young deaf individual, who graduated from high school three years ago at a Federal Institute in São Paulo, Brazil, and currently studies pedagogy at a university in the same state. Two interviews were conducted to understand this student's perception of accessibility and the factors influencing their subject-related preferences and areas of interest. Three analytical categories were developed, covering: accessibility in high school, subject-related affinities, and school relationships. The analyses revealed that educators can implement strategies, such as using conceptual maps and images related to concepts, to enhance visual and accessible teaching. Additionally, the affective factor was noted to be crucial in relation to subject preferences and interpersonal relationships in school. This study is expected to contribute to further research in the field of special education and deaf education, particularly concerning accessibility for deaf students in high school, an area that still lacks in-depth discussions.

Tire recycling poses a challenge due to its non-biodegradable nature and the increasing volume of waste. The asphalt paving industry plays a crucial role by incorporating ground tire rubber (GTR) into modified asphalt binder production, bringing benefits in terms of road maintenance, lifespan, and environmental impact reduction. However, rubberized asphalt faces challenges like phase separation and high viscosity. Solid-State Shear Extrusion (SSSE) technology emerges as a promising alternative to enhance compatibility and adhesion between rubber and asphalt. This study aimed to investigate the properties of modified asphalt binder CAP 50/70 with rubber treated by SSSE. Ground tire rubber (GTR) was produced, both pulverized and partially devulcanized, at two temperatures (100 and 200°C), identified as dGTR100 and dGTR200. Asphalt-rubber samples (LGTR, LdGTR100, and LdGTR200) were prepared with rubber contents of 15, 20, and 25 % by weight of the binder. Physical-chemical, morphological, and thermal tests showed modifications in rubber characteristics post-SSSE, highlighting the temperature's influence on final material properties. Rheological tests indicated superior performance of asphalt-rubber over pure binder, with rubber content and characteristics significantly impacting binder properties. LdGTR100 exhibited better performance than LGTR at high temperatures and storage stability at 20 % rubber content. Therefore, the treatment of rubber by SSSE optimized the interaction between rubber and binder, improving the rheological properties of the rubber asphalt and highlighting its significant potential in the production of modified asphalt binders.

Climate change and the loss of forest biodiversity are two of the biggest challenges faced globally and the protection and forest regeneration of ecologically fragile areas can help to face these problems. However, there are still many challenges to accurately assess forest regeneration. From the hydrological point of view, the Cerrado is where the main Brazilian river basins form and is increasingly suffering from deforestation. This research aimed to contribute to the understanding of the relationship between the morphometry of watersheds and the behavior of natural regeneration through vegetation indices. Data were processed using QGIS 3.22 with GRASS 7.8.2 software. based on data from the IBGE database, the United States Geological Survey and field assessments. The hydrographic basin has an elongated shape, with a compactness coefficient equal to 5.83 (Kc), as well as a shape factor of 0.48 (F) and a circularity index of 0.37 (IC), moving away from the values that represent a circular hydrographic basin, these characteristics indicate a lower concentration of runoff, with lower infiltration capacity. The observed drainage density (Dd) was 2.27 km/km². and 1 of the third order, the average slope found was 8.97%, consistent with the gently undulating relief of the region. The values found for the physical parameters and nutrient concentration are in Class 1 for fresh waters of CONAMA Resolution 365/2005. Analyzing the current situation of the RPPN Águas Perenes, it can be concluded that it is in an advanced stage of regeneration, mainly along the watercourses, with approximately 80% of its area in a medium/advanced stage of regeneration.

This research has the general objective of developing, applying and evaluating a collaborative training program, with a view to the performance of mathematics teachers with students with visual impairment. The specific objectives are: (a) to characterize the pedagogical practices of Mathematics teachers who work in the Final Years of Elementary School; (b) describe the perception of teachers about teaching mathematics to visually impaired students, before and after in-service training. Under a qualitative approach, the study is characterized as a collaborative research. Study participants were three teachers of the Mathematics curricular discipline, working in the Final Years of Elementary School, and a teacher from the resource room for students with visual impairments. The research was carried out in a state public school, in a city in the interior of the state of São Paulo. Data collection and analysis procedures were organized into five stages: characterization of teachers, pedagogical practice, survey of information regarding pedagogical practice, in-service training planning, aplication of training and evaluation of training. The instruments used in the research were: categorization questionnaire; semi-structured interview scripts; fiel journal; collaborative training evaluation script. The collected data were analyzed and organized using the categorical contente analysis technique. The results indicate that in-service training for mathematics teachers provided significant exchanges and reflections between them, favoring accessibility of curricular contentes for students with visual impairments, and this was possible because training was carried out during working hours, based on cases actual students. The study showed the importance of didactic resources and strategies, as important aspects for the success of teaching mathematics for the Middle School in the perspective of school inclusion.

Among the applications of in vitro culture technique of medicinal plants are the use of clonal plantlets from previously selected superior genotypes, the production of metabolites in controlled environment and genetic transformation aiming at the production of specific tissues and metabolites. The in vitro production of secondary metabolites has the advantage of a controlled environment, free of pests and pathogens, in addition to allowing the production of metabolic profile different from those produced in cultivated plants. The present work aimed to establish a protocol for in vitro calli induction and proliferation of the medicinal plant Artemisia annua and to compare the metabolic profile of calli with in vitro plantlets and plants grown in a greenhouse. In addition, the effects of wavelengths of the visible light spectrum (dark, white, blue, red, blue and red) on the production of secondary metabolites were evaluated. The presence of phytoregulators Benzylaminopurine (BAP) and Naphthalene Acetic Acid (NAA) at 1.0 mg L-1 each, promoted the induction and proliferation of calli, with an increase in diameter and fresh weight. SPME GC-MS analyzes showed differences in the metabolic profile produced in different cultivation systems of A. annua and wavelengths used in calli cultivation. White light (cold and fluorescent) and red light (LEDs) resulted in a greater diversity of metabolites produced in calli, with six metabolites found exclusively in calli cultivated under red light, demonstrating specificity of calli response. 27 metabolites were identified exclusively in the calli of A. annua and four of them were reported for the first time in the species: menthyl acetate, geranyl acetate, 4-methoxy benzaldehyde and alpha-santalene. The results demonstrate the potential of in vitro culture of A. annua calli in the production of metabolites different from those obtained in different tissues, such as in vitro plantlets and plants grown in greenhouse.

The present work focused on the study of Novas cartas chilenas, by José Paulo Paes, written throughout 1954 and published by Revista Brasiliense, in 1956. It’s composed of twenty poems, the book allows, using satirical strategies – parody, debasement, ekphrasis, epigram, aphorism, etc. – the establishment of dialogues with some specific moments of Brazilian history. Certainly, with ideological inclination and aesthetic concern, José Paulo Paes used the Cartas chilenas, which were pertinent to the Inconfidência Mineira (1789) process and attributed to Tomás Antônio Gonzaga, for announcing to anonymous and absent audiences those new perspectives and interpretations about Brazil. Finally, the book marks a inflection point in the author’s poetic development as evidenced by the observation that the synthesis, the thematic and formal forcefulness, the ironic thrust, the epigram tendency and the aphorism, the clear ideological inclination and the undeniable creativity become recurrent in aesthetic traits of his later works.

The Covid 19 pandemic claimed thousands of lives and impacted the global economy. To better understand this impact, the present work sought an asset that exemplified the changes that occurred in the financial market during the period, finding in Café Arábica an asset of global relevance, which fulfills the proposed objective. The work was conducted in two stages, the first stage being the research through a systematic review of the literature that sought robust and reliable methods for identifying price bubbles in commodities, finding these characteristics in the variations of the econometric test "ADF". In the second stage, the study uses the “Backward Sup Augmented Dickey-Fuller” (BSADF) test to perform an analysis of the occurrence of bubbles in the Arabica Coffee futures market between the years 2014 and 2021. The results show a large increase in intensity and duration of bubbles during the Covid-19 pandemic period (2020 and 2021). The analysis also suggests the possibility of a substantial increase in the duration and intensity of price bubbles in commodity assets from the year 2011 onwards. The result makes a significant contribution to the existing literature and provides advisory material to professionals who work directly or indirectly in the financial market.
