Given the important role of fashion in the construction of social identities and the actual relevance of digital media, this dissertation aims to analyze how gender subjectivation processes take shape through fast-fashion discourses regarding digital influencers. Characterized by technological as well as social transformations, the digital age made it possible to create personal or corporative accounts in digital platforms. Consequently, corporate accounts started to post fashion images which enabled interaction through “comments” and “likes”. In this way, any personal account interested could engage interaction. Hence, the digital age became responsible for a major shift on gender and fashion related studies in the Sociology field, since it enabled different forms of interaction, sociability and subjectivity. Before the digital age, it was actually possible for some researchers to question to what extent traditional media really got through its public, since they barely seemed to be paying attention (given that they didn´t have the habit of commenting those contents). A completely different scenario seems to be on display nowadays, since the hundreds and thousands of likes and comments show an exact opposite behavior from that of the public back then. This certainly challenges the very questions some of these researchers posed before. Given this shift, in order to investigate its impact on the analysis proposed here initially, this dissertation takes @cea_brasil as its field site. More specifically, there were selected posts where, majorly, BBB21 participants were the main subjects. Methodologically, an incursion inspired by digital ethnography was conducted. Techniques such as participant and non-participant observation as well as semi-structured interviews were used. The interviews were conducted with those who either commented or liked the posts @cea_brasil. As theoretical references, there were taken into account authors who work from a foucaultian viewpoint, such as Judith Butler and Manuel Castells. As main results, the subjectivation processes were comprehended to destabilize the heterosexual power matrix from within the many tensions they dwell.

The road freight transportation activity is highly relevant nowadays, both financially and socially, since human survival depends on the resources transported by road freight transportation. However, cargo transport also has negative impacts, mainly due to the high emission of polluting gases, congestion and traffic accidents. Thus, it is essential to adopt technologies to make road freight transportation more efficient from an operational point of view and make it more sustainable. Knowing that technologies play an important role in road freight transportation, it was identified in the literature that technologies enable specific capabilities for road freight transportation. Thus, the main objective of this thesis is to study the role of capabilities enabled by technology in the road freight transportation system. To achieve these goals, three basic steps are taken. The first stage comprises a multimethod study to identify the capabilities enabled by technology in the road freight transportation system and verify the technological readiness level (TRL) of these capabilities based on secondary data. At this stage, 32 capabilities enabled by technology in the road freight transportation system were identified and organized into six categories (transport infrastructure; transport information; transport management; transport operation; transport monitoring; transport sustainability). In the second stage, the cause-and-effect associations between the resources enabled by the technologies for managing road freight transportation operations were analyzed. For the study of capabilities related to operations management, we used a mixed method approach based on three basic steps: identification and validation of technology-enabled data visibility capabilities; cause and effect association analysis; construction of technology-enabled capabilities framework for data visibility in road freight operations. As a result of the study, a framework was built with 11 technology-enabled capabilities for data visibility in road freight transportation operations. In the third stage of the study, the cause-and-effect associations between technology-enabled data visibility features in road freight transportation operations were analyzed. Basically, the same research method as in the second stage was used in this third stage of the study. The result of this step is a framework with 12 technology-enabled capabilities related to road freight transportation management, and a framework for classifying these capabilities was proposed. Finally, based on the analysis of the three stages of the study, a final conceptual model was proposed, systematizing the results obtained. This conceptual model presents three basic steps: (1) identification of capabilities related to the considered performance factor; (2) identification of which capabilities should be prioritized; (3) identification of which technologies should be prioritized.

This research aims to analyze the visual arts known as "contemporary Afro-Brazilian" through the prism of the African Diaspora. Starting from the following question: How does contemporary Afro-Brazilian art represent the demands of populations constructed as black? I analyzed the exhibition design of the PretAtitude exhibition: Emergencies, Insurgencies, and Affirmations in Contemporary Afro-Brazilian Art, curated by artist Claudinei Roberto da Silva. In this analysis, I sought to highlight the relationship between the Afro-diasporic aesthetics of part of the itinerant exhibitions and their political agency. The objectives were to investigate the catalogs, identifying techniques, themes, and studying the present artists to better understand the aesthetics of each one. Through interviews, I sought to identify how the curator chose the title and what he is referring to with the terms that guide the exhibition. The hypothesis is that, from an artistic perspective and in the exhibition's agenda, we see how Afro-diasporic aesthetics and political agency are connected in a movement to reposition the place of Africa and the contributions of the racialized black population to human history.

Body Centered Cubic (BCC) multicomponent alloys have gained attention in the research of materials for H2 storage. These alloys have the potential to optimize H2 storage properties via compositional control. However, the investigation of the various storage properties is still scarce for these alloys, and the comprehension of hydrogenation reactions is in the early stages. Based on these challenges, this doctoral project aimed to: 1) Investigate the effect of the addition of non-hydride forming elements (M = Cr, Co and Ni) on the hydrogen storage properties and microstructure of multicomponent alloys of the Ti-V-Nb-M system; 2) Identify the formation of possible hydrides and structural changes caused by absorption/desorption reactions; 3) Design alloys of the Ti-V-Nb-M system with different storage properties for various applications. The hydrogen storage experiments, such as pressure-composition-temperature (PCT) diagrams, kinetics of absorption and partial hydrogenation, combined with detailed structural characterizations, allowed us to identify that the alloys absorb H initially forming an intermediate BCC hydride followed by the formation of a face-centered cubic (CFC) hydride reaching storage capacities of 2.4-3.2 wt%. The addition of non-hydride forming elements has been shown to contribute to the formation of secondary phases such as Laves C15 phase. Additionally, it showed influence on the thermodynamics of the CFC hydride formation (increasing the content of these elements results in higher equilibrium pressures for H absorption/desorption). The results also indicated that this influence is related to the valence electron concentration (VEC) of the alloys. Finally, computational thermodynamic tools proved to be excellent tools for the design of alloys with excellent storage properties. These tools allowed the obtention of the Ti11V30Nb28Cr31 BCC alloy with reversible absorption/desorption capacity of 1.7 wt%. of hydrogen at room temperature.

Imbalanced data refers to a dataset where one class has significantly fewer observations than the other class. This can lead to poor performance of both machine learning algorithms and statistical models, since most of these tools assume that the data has the same proportion of observations in both categories. To deal with this challenge, several authors suggest the use of asymmetric link functions in binary regression, instead of the well-known symmetric link functions: logit and probit. Thus, it is possible not only to improve the predictive performance of the model, but also to reduce the bias in the estimation of parameters and probabilities. This is a solution that generates probabilistic models, which excel in decision-making compared to those that simply assign a single class without considering the associated probability. Therefore, this work aims to present new asymmetric link functions generated from the transformations of the Lomax distribution. These functions include the Double Lomax (DLomax), Power Double Lomax (PDLomax), and Reverse Power Double Lomax (RPDLomax) distributions. The proposed functions have proven asymmetry and can be easily implemented in statistical softwares. In addition, the simulation study indicates that these functions can perform better than logistic regression in various imbalanced classification scenarios. They also proved to be promising in modeling real-world datasets, as in this work we obtained better results than classic link functions in two applications.

This research started with the planning and execution of Didactic Sequences in the area of Science, using the construction of a Conceptual Map as a didactic resource for the development of scientific literacy. The activities were carried out by students in the 4th year of Elementary School I, in a post-pandemic reality where relationships were still apathetic, based on their experimental experiences, the resocialization process, developed in a municipal public school in the city of Sorocaba. The Didactic Sequences (SDs) elaborated started from the pedagogical proposals referring to the 4th year, thus, the Water theme was the content adopted following the following strategies: classes and activities on the school Blog, presentation of seminars, carrying out experiments and construction of Conceptual Maps . The research was supported by the theoretical assumptions of Sasseron and Carvalho, Ausubel and Novak, which point to the need to re-dimension the scientific work at school, based on the knowledge of the world that students already have, based on Meaningful Learning through the construction Conceptual Maps and the development of Scientific Literacy. The methodology used is part of a qualitative, descriptive and interpretative approach. For data collection, recordings of the classes were used, the debate of the members of each group and the Conceptual Maps constructed by the students, with the aim of analyzing the resocialization and the development of Scientific Literacy. The results showed that the Conceptual Maps provide an active involvement of the students in the process, showing us in their dialogues, the interaction between peers, the resocialization of each one in the school environment, thus providing learning, living together in a meaningful way, offering possibilities of advancing the exchange of knowledge and collaborating for the development of scientific literacy.

Since its inception, the field of Studies on the relations between STS envisioned understanding the development of science and technology as a human construction, which suffers interference from social, economic and political interests. Thus, we assume that the approximation of these studies with science education is oriented towards social transformation and the socio-political formation of students, which has also resulted in the implementation of discussions on socio-scientific issues (QSC) in education, as well as in the elaboration of of academic works to disseminate these research data. That said, an in-depth analysis of the literature produced is essential, with the aim of understanding the development of this field and its marks on science research and teaching in our country. For this, we used a state-of-the-knowledge survey, so that the information was compiled in two stages: 1) Complete articles published in the Annals of national events in the area (ENPEC, ENEQ, EPEF and ENEBIO) and 2 ) Complete articles published in national journals evaluated as Qualis CAPES A1, A2 and B1 (2013-2016 Quadrennial), in the teaching area. Thus, through the constitution of these data, our analyzes point to the main trends in the field of studies on QSC in Brazil: the majority of production by researchers located in the south-southeast axis, a fact that has changed over the last few years due to the expansion of universities and the creation of graduate programs in the north, northeast and midwest regions of the country. As the main silencings found, we highlight the absence of references for the delimitation of the teaching methodology used, as well as with respect to what training is aimed at with the inclusion of QSC in teaching. Finally, from the analysis of these documents, we seek to contribute to a greater understanding of studies on QSC in Brazil, as well as deepen discussions on trends, silencing and emerging themes of this field of studies in our country.

Brazil is increasingly gaining global prominence in the generation of bioenergy, mainly in the production of ethanol, some residues result from this process, such as vinasse. Because it contains high levels of organic matter, vinasse has been used as fertigation for plant cultivation. However, its application has a high polluting potential when handled incorrectly and can contaminate the soil, surface and groundwater. This study carried out a comparative study of the environmental impact of the application of vinasse in the soil. The study analyzed the evolution of vinasse biodegradation using respirometry and the environmental toxicity levels of in natura and concentrated vinasse to L. sativa. It also verified the soil chemical changes influenced by biofertigation and used Principal Component Analysis in the statistics. Evidence was observed that vinasse biodegradation works well with both raw and concentrated vinasse. In addition, as a result of ecotoxicity, vinasse, when properly applied to the soil, does not harm L. sativa and improves initial plant growth.

A presidential election process can generate rational expectations of a ‘risk premium’ among investors, with a speculative bias due to political uncertainty, allowing for the occurrence of explosive behavior in stock prices. In this study, stock prices were used at 5-minute intraday intervals to identify and date episodes of rational bubbles (explosive dynamics) in the sectors of B3 (Brazilian Stock Exchange and Over-the-Counter Market) throughout the Brazilian electoral process of 2022: comprising between the 5th business day after the start of electoral propaganda (08/23/2022) until the 15th business day after the second round (11/18/2022), totaling 60 trading sessions. To this end, the Generalized Supremum Augmented Dickey-Fuller test was applied in a panel configuration (Panel GSADF), with each B3 sector being a data panel. The following question was sought to be answered: during the Brazilian electoral period of 2022, were there rational bubbles in the B3 sectors? With the Panel GSADF test methodology, it was possible to detect multiple bubble episodes in the Oil, Gas and Biofuel (2 episodes), Health (2 episodes) and Information Technology (5 episodes) sectors. November 16th presented bubble episodes in these three sectors, with the Health sector having the longest explosive behavior. The studies and results presented in this work may be useful for theoretical and empirical researchers, economic authorities and private sector agents in order to become aware of mechanisms to identify bubbles in financial markets and measure their extensions.

With the increasing population and demand for food, increasing crop productivity without expanding agricultural land is a crucial challenge. Soil chemical analysis and foliar diagnosis are important tools to ensure healthy plant development, assisting in the decision-making process for the appropriate and sustainable application of inputs, especially fertilizers, amendments, and pesticides. In this context, the LIBS technique stands out for allowing quick and multi-elemental analysis with minimal or no sample preparation. LIBS also has a wide range of configurations, with the most common being single-pulse (SP-LIBS) and double-pulse (DP-LIBS) configurations. However, analyzing data generated by LIBS is complex, requiring automation. This work presents the development of a software called LIBSsa, which automates the analysis of LIBS data to develop quantification models of macro and micronutrients in sugarcane, coffee, and soybean leaves. The software was created in Python, a widely used language in both scientific and corporate environments, mainly for being open-source and offering a wide range of scientific tools. In addition, protocols for foliar analysis with LIBS were proposed, using two sets of samples: Set 1, measured in a DP-LIBS system, and Set 2, measured in an SP-LIBS system. Promising results were obtained, where for Set 1 samples, quantification models were obtained for Ca, Mg, Mn, and P, with calibration and validation correlations above 83%, while for Set 2 samples, quantification models were obtained for Al, Cu, Fe, K, and Zn, with calibration and validation correlations above 70%. All results were obtained using LIBSsa, which proved to be intuitive and computationally efficient, in addition to having open-source code, offering a promising path for quick and accurate nutrient analysis in plants using LIBS.

Cannabis, popularly known in Brazil as "marijuana", has been used culturally by humans for millennia. It is indicated that, currently, its use is associated with several purposes: medicinal, gastronomic, industrial and social (known as "recreational", and also named as "adult use"). This research presents from a historical perspective, the social developments of the illegality of Cannabis, the cultural context of Cannabis, in addition to the industrial use and medicinal use of Cannabis. Particularities about the development of science, the characteristics of scientific communication and the development of scientific journals are discussed. This research found answers, in scientific periodicals specialized in Cannabis, regarding the status of its medicinal use. As for the method used to identify the universe to be researched, it allowed the identification of scientific journals in Ulrich's, which has an editorial scope focused on Cannabis studies, available in open access, namely: [1] Cannabis, [2] Cannabis and Cannabinoid Research, [3] Journal of Cannabis Research and [4] Medical Cannabis and Cannabinoids. In addition, it was confirmed that the pathways that characterize open access publications expand the reach of scientific communication and optimize access to the publications themselves, also amplify the social value of research, the value of funding agencies and research institutions. The reading and analysis of the keywords, title and abstract of each material allowed the identification of thematic nuclei of the documents, enabling the creation of categories of analysis according to Bardin's (1977) proposal. The following research themes were identified: treatment of pain of different origins; use of cannabinoids as substitutes for other medications; management of endometriosis; treatment for arthritis; treatment of inflammatory bowel diseases; treatment for sickle cell disease; treatment for cachexia; treatment for refractory stuttering; treatment for anxiety; medicinal use of Cannabis for COVID-19; self-medication with Cannabis; treatments for Cannabis overuse disorders; drug interactions; cannabidiol (CBD); other cannabinoids; chemical components of Cannabis and its derivatives; perioperative uses of Cannabis; consumption patterns for medicinal purposes; healthcare professionals; patients using Cannabis for medicinal purposes; studies and reviews. It is stated that the therapeutic potential of Cannabis is vast, a fact that allows the topic to assume a significant role in scientific studies soon, as well as to expand its own use in medicine.

The inquiry-based teaching is configured as a didactic approach and in recent years has been highlighted, mainly by the characteristic of changing the dynamics of practices in order to attract students' attention to scientific issues and promoting scientific literacy. In order to keep the effectiveness of the investigative process in school units, it is important for future science teachers to know and be able to carry out investigative activities. To this end, it is necessary to discuss and analyze how initial training courses consider and should consider this issue. Faced with the need to achieve initial training from this perspective, the present research seek to identify which training subsidies are necessary for undergraduates in science to build knowledge teachers related to inquiry-based teaching and to analyze the development of these subsidies so that they help pedagogical actions related to the planning and application of investigative activities through a systematic literature review, the development of an formative activity, the Curricular Activity to Integrate Teaching, Research and Extension (ACIEPE) and the promotion of strategies. Therefore, for the analysis of the data the methodology of content analysis was used. The results pointed out by the literature show five possibilities of training subsidies, namely: Theoretical Foundation; Practical Opportunities; Collectivity; Reflection; and Formative Changes. Moreover, it was also possible to observe two more manners of training subsidies, pointed out by undergraduates and teachers, namely: Language adaptations and Knowledge and Legal Support. From this, it was possible to draw relationships between the results and propose possibilities and ways of approaching such subsidies in initial training.

The agroecosystem is a complex structure that requires a holistic analysis at the landscape level and should not be considered merely as an isolated agricultural production site. It is essential to examine the relationships among people, crops, animals, soil, and water to promote the integration of new technologies. In this regard, this research plays an important role in using remote sensing to study a diverse agroecosystem with the aim of analyzing the behavior of different tree density levels on pasture areas and investigating whether this influence is perceived by family farmers in the Amazon Portal. By using CBERS-4A satellite images in the Jacaminho Settlement Project, it was possible to map tree coverage and delimit sample areas with "High, Medium, and Low" tree densities. The Normalized Difference Vegetation Index (NDVI) was calculated for images from four different dates. It was observed that areas with higher tree densities (20-30%) exhibited the best average NDVI during the dry season. The interviewed farmers highlighted the benefits of trees in their pastures and pointed out the lack of planning in implementing tree areas due to the absence of supportive public policies. Remote sensing proved to be effective in measuring pasture quality based on tree arrangements.

Greening (Huanglongbing/HLB) is the most destructive citrus disease. It is caused by the bacterium Candidatus Liberibacter asiaticus (CLas), C. Liberibacter africanus and C. Liberibacter americanus and it is transmited by the insect vector psyllid Diaphorina citri. There is no commercial variety of crown plant or rootstock resistant to disease and contaminated plants cannot be cured. Despite of considerable research, there is little knowledge about the processes involved in plant infection and colonization by CL. A study of the plant/bacteria interaction CLas was developed by LC-HRMS/qTOF in positive and negative ionization modes. Central and lateral roots of healthy and CLas-infected plants of C. sinensis x C. limonia cultivated in a greenhouse, and the roots of healthy and infected C. sinensis seedlings cultivated in vitro were analyzed. Through the analysis of the molecular network, it was possible to observe an increase in the concentration of some metabolites in plants infected with HLB. Significant differences using the paired two sample t-test were observed in the concentration of demethylsuberosin, osthenol, 5-methoxyseselin, xanthylethin, seselin and limonin for plants grown in a greenhouse and for xanthylethin, seselin and limonin in seedlings grown in vitro. The compounds mentioned above, were responsible for the classification observed in the PCA analysis, that classified the samples in four groups: roots, lateral roots, lateral roots of health plants and lateral roots of infected plants. The quantification of the expression of DXR, DXS2, PT1 and PT2 genes was carried out by qPCR, in C. sinensis x C. limonia roots of healthy and symptomatic plants infected with CLas. There was a decrease in the expression of the DXR, DXS2 and PT1 genes in plants infected with CLas compared to healthy ones. For DXR, a two-fold decrease in gene expression was observed, for DXS2 by 5.7-fold and for PT1 by 3.6-fold. For the PT2 gene, there was an increase in relative expression for infected plants compared to healthy ones of 2.6 times. These results show that the plant responds by producing some metabolites in greater or lesser quantities in the presence of CLas bacteria, in addition to causing changes in gene expression in the pyranocoumarin biosynthesis pathway. Therefore, a plant reaction is observed inhibiting the biosynthesis of linear coumarin derivatives in favor of angular ones, which are prenylated at C-8.

The enduring permanence and expressiveness of the sertanejo style of popular song allows spontaneous recognition regarding its ongoing transformation in the most diverse aspects that can be observed, whether in materiality, or in the discursive or social aspects articulated interdependently with it. The general objective of this thesis involves describing, interpreting and proposing an explanation about this transformation, having as specific focuses: (a) the role of language in its dialectical relationship with the social structure in country song texts and the constant transformation of style; and (b) the investigation around the permanence or erasures of the caipira objectified by Darcy Ribeiro (1995) in the so-called sertaneja discursive formations. The theoretical foundation proposes and applies a field of interaction between some elements of Song Semiotics (TATIT [1996] 2012), a theory that pioneers accommodate song texts in the field of linguistic studies, and Critical Discourse Analysis (FAIRCLOUGH, 1989; [1992] 2001, [2005] 2012), which interrelates in an elegant way summarized in an efficient theoretical-methodological model language, discourse and society. I make use of the work of Chitãozinho & Xororó between the years 1970-2022, which, among countless consecrations, actively participated in different ordinances of the field, which implies both the dialogue with countless artists belonging to different genres at different times and the active inclusion in diverse business models. As a corpus, a presentation of a concert linked to the Evidências tour (2017-2020) whose analyzes are more specifically focused on the songs. The show consists of 24 song texts, taken in terms of translation (JAKOBSON, [1959] 2010) of their source texts, these referring to the period 1970-2010. Aiming to increase the concreteness of the analyses, the research includes external observations, semi-structured interviews (CRESWELL, 2010) and personal communications with professionals linked to the pair. Despite the mention of the field and its figurative isotopies enriched by singing in a duet, nasally invested with falsettos and vibratos, which suggests a cohesive link in the style, which is endowed with such material traits in its roots (LIMA, 1972), the results point to the erasure of the caipira described by Ribeiro (1995) in the so-called sertaneja song due to factors that articulate the desire of the artists themselves to disassimilate the social stigmas imputed to them and interests of the Cultural Industry and its constant scope of entertainment in different semantic fillings structured and structuring texts.

Prenatal cares constitute an important moment to exercise the healthcare functions, including health promotion, sorting, diagnosis and disease prevention, constituting a set of actions that are simultaneously preventive, health promoting, diagnostical and healing, aiming good outcomes of the pregnancy for women and newborns. The objectives of this thesis are: understand, describe and evaluate Prenatal Nursing Care (PN), aiming at it’s qualification, in the context of the COVID-19 pandemic; understand the potentialities and needs of nurses for the qualification of the PN in the context of the pandemic; identify practical measures to qualify prenatal care; redirect actions to implement the activities proposed by the health teams. Methods: the action research was used because it is an interventionist method, in which the researcher leaves the position of spectator and together with the studied population, tests the hypotheses about the phenomenon of interest, implementing and accessing changes in the real scenario. For this, six nurses from the main Basic Health Units in Primary Health Care in the city of São Carlos participated in this research. Results and Discussion:This study showed that there is a distance between the nurse and Prenatal Care, whose current model of care does not belong to pregnant and puerperal women and also does not belong to nurses. The pandemic intensified this distance and the nurses remained agents of information and guidance. The nurse's role is solitary and subordinate to the doctor's work. Without enough strength to do their actions differently, the nurses prefer the comfort of safe stability than the turbulence of a fight for freedom, as a result of the perception that the challenge is bigger than the condition of confrontation. Final considerations: there is an evident need to recognize the importance of health care, the creation of spaces for dialogue and knowledge exchanges between nurses and pregnant women, favored by the group of pregnant women as well as between the nurses, provided by the study group/work. The model of care lines must be recognized as a strategy to overcome the fragmentation of the attention and management in the search for the challenges and scope of comprehensive care for the pregnant woman and her family, which will imply in a work processes review, the association, interactions, support and commitment of the management team with the identified tensions. The qualification of Nurses' Prenatal Care will only be possible with a change in the work process and greater commitment from the municipal public management.

This thesis consists of three studies that address the theme of self-esteem in Behavior Analysis. The first study is a systematic review of specific Behavior Analysis books and journals on self-esteem. Key findings include the scarcity of studies and the lack of a well-established behavioral definition for the concept. The second is a theoretical study that seeks to understand the concept of self to comprehend self-esteem and proposes a behavioral definition that takes into account the relevant factors in its construction, especially social interactions. The third study investigates the applicability of the Function Acquisition Speed Test (FAST) in measuring self-esteem, comparing the results obtained with those of a Rosenberg Self-Esteem Scale. The results indicate positive self-esteem in participants, both in the FAST and the Rosenberg Self-Esteem Scale, though no correlation was found between the results of the two instruments. Together, these studies contribute to a broader understanding of self-esteem from a behavioral perspective and explore different methods of assessing this psychological construct.

Life cycle assessment is an environmental, economic, and social evaluation technique focused on understanding and quantifying the impacts related to a particular product, good, or service. This assessment considers all stages in which it performs its function, from obtaining resources for production to final disposal. Often, the production stage generates various marketable products, such as in biorefineries, industries whose backbone is the production of biofuels along with a portfolio of other higher-value-added products. Although the contribution of industrial processing to environmental impact is typically lower than that of the agricultural sector, it is from the gates of these multiproduct processes that the final products emerge. Thus, the method employed for allocating environmental impact indices to the various products plays a crucial role in valuing, comparing, and improving production processes. However, there is still no consensus on the most appropriate allocation method. In this context, the objective of this study was to develop a systematic, first-principles-based method for detailed accounting of impacts throughout the industrial process. The new proposed method was compared to the global allocation approach, taking as a case study a sugarcane biorefinery producing ethanol and electricity. In this case study, the proposed allocation method calculated an impact of 27.44 g CO2 eq/MJ for anhydrous ethanol and 4.68 g CO2 eq/MJ for electricity, representing 94.11% and 5.81% of the total impacts of the analyzed process, respectively. In comparison, the classical energy allocation method calculated an impact of 21.89 g CO2 eq/MJ for both products, representing 75.08% for ethanol and 24.92% for electricity. It was found that the proposed method allowed for separating the impacts associated with each production process, without penalizing one product for the impacts generated by the other product. Furthermore, the method enables the visualization of impact flows through the process, aiding in identifying sustainability bottlenecks and optimizing the process.

It is expected that in the coming decades, natural gas, consisting mainly of methane, will become an important raw material in the industry to produce chemicals and intermediates. Thus, it is of great interest to develop processes for the direct oxidation of methane to methanol via more sustainable and cost-effective routes, which would also reduce methane emissions to the atmosphere and, consequently, its impact as a greenhouse gas. Despite the scientific advances achieved in the study of this process, the breakage of the C-H bonds of the methane molecule remains a challenge, which has encouraged the development of highly active and selective catalysts. The studies have focused on exchanging zeolites with oxidized metallic cations to recreate the reactivity mechanism like that found in the enzyme methane monooxygenase, which converts methane to methanol under atmospheric conditions of temperature and pressure. In the discussed context, the objective of the work was to study the direct oxidation of methane to methanol over zeolites Y and mordenite exchanged with copper oxo-cations, analyzing the influence of the zeolitic structure and the activation conditions on the formation, nature, and activity of the generated species, as well as the conditions related to the methane reaction. The activated Cu-zeolites were characterized by energy-dispersive X-ray spectroscopy, X-ray diffraction, nitrogen physisorption, scanning electron microscopy, hydrogen, and methane temperature-programmed reduction, and in situ Fourier transform infrared spectroscopy by transmission mode. In order to determine the active species generated during activation and their subsequent consumption during methane reaction, both operated isothermally, in situ ultraviolet-visible diffuse reflectance spectroscopy analysis was performed. All the studied Cu-zeolites were able to convert methane to methanol. The activity profiles of the zeolite Y and mordenite were associated with the nature of the generated active copper species and their reaction temperature with methane. The in situ DRS-UV-Vis spectra showed bands related to dimeric and trimeric copper species in both the studied Cu-zeolites. Formation of monomeric active copper species was also observed for mordenite.
