Water scarcity and contamination of water bodies are relevant concerns in the present time. The utilization of microalgae represents a promising technology for enhancing domestic wastewater treatment processes and the production of compounds of interest such as lipids, carotenoids, and dyes. During the tertiary phase of effluent treatment, the use of microalgae primarily aims at the direct removal of nutrients such as phosphorus, nitrogen, and carbon through assimilation for biomass production. However, there are several obstacles that hinder the full integration of microalgae usage in wastewater treatment plants. This present study aimed to assess and enhance the photobioreactor developed by C4 Científica, with a focus on optimizing nutrient removal and biomass production. Batch experiments were conducted over periods ranging from seven to ten days, using different sewage sources and light conditions to quantify the removal of total nitrogen, phosphorus, and carbon, as well as the biomass production of the microalga Chlorella sorokiniana. The modification of the photobioreactor led to a total nitrogen removal of 85% and a total phosphorus removal of 90%, along with a maximum biomass concentration of 325 mgL-1 of dry biomass. Furthermore, a 99% removal of colony-forming units of E. coli was achieved. The enhancement following the photobioreactor modification resulted in a 36% increase in biomass production, a reduction in the LOG phase, and improved consistency in the rates of total phosphorus and total nitrogen removal. The addition of 5% (V/V) CO2 did not show improvement in productive parameters or nutrient removal efficiency. The Photobioreactor exhibited a pronounced nutrient removal capacity and can be employed for wastewater polishing, making the effluents suitable for disposal into water bodies after treatment.

Amphibians are a group of vertebrates that have had a great decline in recent years due to the great anthropic interference in the environment, causing loss of habitat, inclusion of invasive species and the manifestation of diseases. These factors contributed to the extension of species and the decrease of different individuals. With these problems in mind, there is an increasing concern to conduct minimally invasive research, preserving the integrity and well-being of the specimens as much as possible, and providing quality research with satisfactory results. Therefore, for this master's thesis, a systematic review was carried out plus a scientometric analysis of scientific articles on alternative less invasive methods (which totaled 61 articles). In addition, an analysis was made of how portable glucometers can be adapted to studies with amphibians as a less invasive method for collecting blood glucose data as a potential biomarker indicative of stress. The systemic review revealed several areas of research in which alternative and less invasive methods have been applied in studies with amphibians, including molecular analyses, morphometric measurements, molecular analyses, and marking of individuals, imaging exams, even the reuse of carcasses of animals that were run over on roads to obtain biological certification. Despite the application of these methods, there is an urgent need for incentives for scientists to expand the adaptation of these methodologies in their studies, especially in the areas of environmental monitoring and ecotoxicology, in which the use of animal models is frequent. In the second chapter of the dissertation, the comparison between the blood glucose values between males and females of R.ictérica showed that there was no significant difference between the sexes for the values obtained through the portable glucometer (F = 1.15; p = 0.63 ), followed by the biochemical analytical method (F = 1.047; p = 0.66), indicating homogeneous glycemic values. When grouping the data of each as independent, the mean blood glucose values were similar (F = 1.050; p = 0.4819), which did not occur when dependent, showing difference in incidence (p < 0.0001; r = 0.979). Thus, it was shown that the glucometer is efficient, but tends to overestimate the glycemic levels.

In this research project, we investigate the method known as \textit{continuous dynamical decoupling}, which is based on the use of continuously applied external fields to maximize the fidelity of quantum logical operations performed on a qubit experiencing decoherence. In our model, we assume an open quantum system in which a qubit continuously interacts with its surroundings, and thus we say that the qubit is coupled to the environment, which irreversibly disturbs it, causing decoherence. The \textit{continuous dynamical decoupling} tells us that assuming a known error operator and an environment represented by a field of scalar bosons at a finite temperature, decoherence during logical operations can be efficiently reduced by applying a superposition of two external vector fields: one rotating orthogonally to the direction of the other, which remains static. The main objective of this project is to improve the method by finding optimized directions of external fields that, when continuously applied, maximize the fidelity of logical operations performed on a qubit. To achieve this, we will need to numerically solve the master equation of the system – where the external fields will be applied with variable directions (variable angles) during the optimization process – in order to find the best protective fields for a given logical operation. Finally, we present the results obtained for a qubit in an environment with ohmic spectral density and briefly discuss the findings.

It is common in the industrial and clinical context to seek more precision, accurate, accessible and cheaper equipments. Therefore, it is important for these fields to have a way to compare the agreement of new devices with one that already exists and that is assumed to be reliable and accurate. On the other hand, it is increasingly common that systems record data over time with a very fine discretization, creating functional data. Considering this scenario, we propose the approach “Predictive Probability of Functional Agreement” (PPFA), a technique for analyzing the concordance between functional data under a Bayesian perspective, which allows determining whether two systems can be used interchangeably (a nomenclature used in studies of comparison of measurement system). The PPFA generates an intuitive measure of agreement (the predictive probability) of the curves from a new subject (from both devices) differ by less than an acceptable amount for the field. An example of equipments that need further analysis on the degree of agreement are the Optotrak and the flexible electrogoniometer. These systems are used in gait studies. The Optotrak is a laboratory device and generates accurate data, while the electrogoniometer is an ambulatory and cheaper equipment than Optotrak. In order to carry out the comparison study between the Optotrak and the electrogoniometer with our Predictive Probability of Functional Agreement tool, we need to assume a model. Therefore, we present the Bayesian Functional Gaussian Process hierarchical model (BFGP). The PPFA is a simple and intuitive approach, while the BFGP is an easily interpreted model for the gait problem.

Considering diversity, it is very important to study and reflect about inclusion, the pedagogical practices involved, and especially to relate it to natural sciences and social and emotional competences. And, through the political decisions made as a result of the historical processes it is noted that inclusion is one of the challenges most loaded with individual and collective psychological aspects. In this context, a major challenge is to associate inclusive education with the natural science disciplines, while it is necessary to understand what factors may be linked to the problems faced in the classroom with students targeted for special education and link the so-called social and emotional competencies. For this reason, this project aims to investigate the implications/interferences of attitudinal barriers in the teaching-learning process of students in the area of natural sciences and how this reflects on the inclusion process. The research was carried out in a school of the Pirassununga Board of Education, with semi-structured interviews for the respective teachers and resource room teachers who accompany the student. The methodology will adopt qualitative exploratory research assumptions, using Descriptive Textual Analysis techniques to analyze the text corpus, which will consist of transcribed interviews. As a result, it is expected that the research can contribute in several aspects research in the area of education, making data available for new work in teacher training and inclusive education; Contact of different education professionals, who may reflect on the way they deal with inclusive education, reflecting on the influence of attitudinal barriers in everyday school life; Structure possible didactic material for natural sciences teachers regarding inclusive education (first edition), with topics ranging from theoretical and practical content to assessments; Production of knowledge in the area, and articles to be published in scientific events and/or journals, to supply the lack of research in the area, as pointed out throughout the dissertation.

Starting university can be a time of several changes for young people, concerning their daily life, support networks and educational dynamics. This context can be harmful to students' mental health, making it necessary to promote health care practices. Meditation is a practice that can improve everyday life. Objectives: this study aimed to systematize the experience of creating and conducting a meditation project offered between 2018 and 2023; analyze the experience as a group device, meeting, learning, and welcoming, considering professional training in occupational therapy degree. Methodology: a qualitative study with an autobiographical approach was conducted using narrative and reflective descriptions. The analysis of the experience was performed using references from the Encounter Group (by Carl Rogers) and the Operative Group (by Enrique Pichon-Rivière). Results: the narrative made it possible to recall events, records, and photos based on the construction of a timeline containing professional training movements during graduation, in-depth studies in the field, and the process of meditation meetings. The Presença Project emerged from individual initiatives and collective interests in meditation in the university environment. Studies on meditation techniques were sought to support the continuity of meetings over time. During the project, the initiative was expanded to other contexts. Discussion: In association with Pichon’s inverted cone learning process, aspects of care that contributed to the learning of meditative techniques were identified, such as the environment, group management, relevance of events, moments of sharing, and interpersonal cooperation. The development of empathy, congruence, and unconditional acceptance (Rogers) were fundamental in allowing the group to be led with more freedom and intuition, based on personal and undergraduate life experiences. Conclusion: The training process in occupational therapy contributed to the foundation of knowledge about group theories, therapeutic bond construction, and the development of a singularized care process. Institutional support, such as research support grants, favored dedication to deepening studies and improving the project. In this case, it was observed that groupality is composed of a constant interaction within the person, group, and coordination. In the case of the Presença Project, meditation was a determining factor in forming bases for bonding, groupality, and the development of care strategies in the university daily context.

TEACHING TOOLS IN THE CONCEPT OF NANOTECHNOLOGY IN BASIC EDUCATION. Nanotechnology has a high impact on people's quality of life, being present in the development of clean energy, more efficient mobile devices, the treatment of diseases, the production of prosthetics, cosmetics, pharmaceuticals, among others. However, the clarity and understanding with which this topic has been discussed in the media is questioned, so the aim is to clarify whether this knowledge is being announced to students in a way that is dissociated from their reality. It is also clear that despite the large amount of information available, quality is sometimes lacking in its preparation, failing to highlight fundamental points, such as its definition, impacts and relevance for the development of society. Therefore, through this work, it is proposed to apply a didactic sequence to a class of high school students from a public school in São Paulo, in order to verify their level of knowledge and familiarity with the topic of N&N, and also, teach basic and fundamental concepts regarding nanometric materials, their benefits and risks, advantages and disadvantages of their applications, seeking to encourage the development of a critical opinion based on scientific knowledge. To achieve this, this sequence was carried out in four classes, the first being a diagnostic assessment and debate, the second a demonstrative experimental practice, the third constitutes a presentation of student seminars on N&N applications, and the fourth was a final questionnaire on the content covered in the classes taught. It was concluded that students' knowledge about nanotechnology and nanoscience is still superficial, despite the profusion of currently existing technological applications and their dissemination in the media. Furthermore, there is a lack of cohesion in the writing and interpretation of texts in their responses and there is great difficulty in assimilating associated chemical concepts, so that a greater focus in future work on reading and the development of formal and chemical writing is suggested.

The urbanization of cities increases as climate disruptions occur at the local scale. Therefore, it is considered important to study the dynamics of cities and the relationship between the urban climate, since it is on this scale that profound transformations take place. In view of this, this work aimed to analyze the surface heat islands and the urban canopy layer in Sorocaba/SP, based on the classification of LCZs in the municipality. The following methodologies were used: detection of surface heat islands through thermal images from the Landsat 8 satellite, definition of LCZs through the LCZ generating system, measurement of air temperature and relative air humidity through mobile transects and categorization of intensities of climatic heat islands. The results demonstrated that surface heat islands and climatic heat islands of fragility, medium and strong magnitudes occur in compact lowrise LCZs (LCZ3) throughout the urban patch. It was concluded that there are heat islands in Sorocaba.

In Brazil, one of the biggest cultural movements of peripheral youth in the 20th and 21st centuries is Funk, which emerged from urban popular culture, mainly in the states of Rio de Janeiro and São Paulo. The funk movement aims to contest and challenge the hegemonic system, through music, dance, “dances” and its own aesthetics, evidenced by clothes, haircuts and accessories, popularly called “kit”. The central figure of funk culture is the boy, black, poor and from the favelas, who, contrary to the silencing structure in which he is daily inferiorized and segregated, through funk performance in search of protagonism. This protagonism can be read concretely in most funk lyrics. We could affirm that through funk, these young people exercise their cultural citizenship rights on a daily basis, as Chauí (2008) has proposed, as they actively insert themselves in their territories, produce themselves as subjects and invent forms of social participation in cultural circuits and politicians.This research aims to understand how black, peripheral and funk culture has produced the possibility of existence, creation and transformation of realities. As well as highlighting how the production of mental health occurs in this context, understanding here, mental health not as the absence of a disorder or illness, but as the experience of citizenship itself, subjectivation and the possibility of existing and creating new experiences and spaces of belonging in the world, that is, in the sense of the collective production of subjectivity. For this, methodologically, intervention research was used, with cartographic reference based on the interview technique to produce data in dialogue with the concept of Writing by the author Conceição Evaristo. Six self-declared young participants, black, peripheral and funk fans, were interviewed. The results were presented based on eight dimensions: (1) characterization of participants, (2) Conceptions of mental health, (3) Black emotionality, (4) Memories, belongings and records, (5) Collective and political action, ( 6) the body, corporeality and the aesthetic dimension, (7) Racism and everyday life and (8) Negritude, funk and the field of mental health. It concludes that the field of mental health is urgently positioned to contribute to the promotion of racial equity and the deinstitutionalization of racism, which David and Vicentin (2020) called the Aquilombamento process. In this sense, funk cultural production needs to be highlighted in this field, since it presents itself as a powerful expression of the ethical, aesthetic and political dimensions of the mental health of the young black Brazilian population, and points us to clues for the production of care practices and of social transformation.

The Brazilian Atlantic Forest (BAF) is globally recognized as a biodiversity hotspot, harboring high species richness and endemicity while suffering from intense anthropogenic threat. Three Pleistocene climate refuge centers are recognized in this biome: São Paulo, Bahia and Pernambuco. However, rapid contemporary climate change associated with other anthropogenic activities reduces species distribution area, impacting species richness, and may result in the extinctions of many species. To understand the responses of medium and large mammals of the BAF to climate change, we built species distribution models and compared species richness and endemicity for the past (21 000 years ago), present and future (2081-2100). We also examined the potential change in distribution between the present and the future in each of the BAF refugia. To understand the evolutionary history of the communities, we calculated the phylogenetic diversity of each refuge. We observed patterns of contemporary richness and areas of endemism congruent with the areas of the Pleistocene refugia. Phylogenetic diversity revealed different evolutionary histories in each refuge and the presence of phylogenetically distant species in the area of lowest richness (Pernambuco refuge), indicating that ecological diversity may be preserved. Our results highlight the widespread and negative impacts of climate change on mammal distribution. The species distribution modeling approach requires accurate and reliable species identification and occurrence data. Many mammal species, especially carnivores, occur at low densities, which makes them difficult to detect and study. Through a systematic literature review we explored how fecal DNA, a noninvasive sampling approach, has been used to study carnivore species considered rare. We investigated the applications and techniques that have been employed, the sampling effort required and the efficacy of fecal DNA in detecting rare carnivores. We compiled data from 250 papers and found that fecal DNA is a valuable source of genetic material for determining species, individual identity, and sex, among other applications. Fecal DNA was found to be more and equally efficient in determining the number of individuals and species present, respectively, compared to alternative methods. Among the three BAF refugia, the Pernambuco Endemism Center (PEC) or Pernambuco refuge deserves to be highlighted for its smaller area, scarce studies, and intense anthropogenic threat, resulting in habitat loss, fragmentation, and degradation. Therefore, it is essential to determine the efficiency of sampling methods to produce rapid and reliable assessments. We compared five noninvasive survey methods to assess the medium-sized mammal community in a forest fragment immersed in a sugarcane matrix. We identified thirteen species and discussed the results in relation to the group of species detected, the proportional detection success and the latency to first detection of each method. We expanded the molecular identification of feces to six important areas of the PEC in the state of Alagoas searching for native Canidae and Felidae species. We identified two species: Leopardus tigrinus and Cedocyon thous. The results show the usefulness of fecal DNA sampling for detecting rare species, such as L. tigrinus, but also reinforce the process of defaunation in the region. The findings in each of these chapters are relevant to the conservation of mammals in the Brazilian Atlantic Forest, shedding light on strategies and actions that can be taken to preserve the biological diversity of this ecosystem.

The increase in impacts resulting from soil sealing and the inefficiency of conventional urban drainage systems has been emphasizing with greater magnitude, the need to rethink the conventional urban planning implemented in a large part of Brazil. Several alternative approaches to conventional stormwater management are known and successfully applied internationally; and, at a national level, they are in the (slow) process of being incorporated into the technical environment. The use of Detention Basins - BD to control and/or avoid new flooding points, in Brazilian cities of different sizes, is an increasingly common practice that demonstrates efforts to minimize such impacts, as well as reinforce the inefficiency of the existing infrastructure for current climatic and urban conditions. In view of this context of increasing advances in the adoption of these measures, the present study seeks to demonstrate, based on the proposition and application of a Simplified Method of Calculation and Evaluation of the combined use of CT (aailable at the link: https://drive.google.com/drive/folders/18zHM ObhFsCdC8Y6rbsf7RxWcP6lzP0c0?usp=drive_link), that the temporary storage and/or infiltration must be studied/planned from the lot scale, with the use of existing public areas in the allotment, called Lowered Green Areas - AVR. For this, four simulation arrangements were defined, namely: (1) without AVR; (2) with AVR in lots; (3) with AVR in public areas; and (4) with AVR on lots and public areas. This set of arrangements were simulated in three study areas, with different land use and occupation, but all with Detention Basins. The adopted parameter of comparison was the reduction of the dimensions of the BD, due to the distribution of AVR upstream. The simulations were carried out and, as expected, there was a reduction in the volumes of detention, and it was even possible to discard this unit, in some cases. The lag of peak times depended on the dimensions of the AVR (subject to change by the user), varying according to the rainfall adopted. These results proved to be positive for the implementation of storage and infiltration structures at different scales, but emphasizing that all these combinations influenced the reduction of the surface runoff volume and the delay of the peak flow; having little influence on the absolute value of the latter for the post-occupancy condition. The analysis of the hydrological behavior, through the entry and exit hydrographs of the BD, made it possible to identify that in addition to the hydrological benefits, it is essential to define other possible non-hydrological aspects for choosing the best arrangement. Finally, it was demonstrated that the development of a simplified method of calculating and evaluating compensatory techniques constitutes an instrument that can greatly facilitate the study of the use of these techniques, in an isolated or combined way, expanding their possibilities, but also identifying its limitations.

The advancement of science and technology at the nanoscale boosted an increase in the nanostructured ceramic materials applications, from the manufacture of electronic components to scaffolds for human bones development. Amongst these materials, metallic oxides are of particular interest due to the range of possible applications, notoriously optical, electrical, and magnetic properties. Uniting their properties with quantum effects related to the nanoscale, materials with high performance (i.e., improved properties) or even new applications (i.e., new or atypical properties, not found in their bulk equivalent) find important employability in the modern industry. Consequently, there is a great demand for more efficient and green synthetic techniques, combining production, speed and lowers costs. Spray pyrolysis is one of most important technique in this group by its low cost and high efficiency in the production of powders and nanostructured films, well known in the manufacture of photovoltaic cells, catalytic processes, among other diverse applications related to film formation and nanostructured material production. In face of its potential, this study focusses on the development of spray pyrolysis by using microwave as a heating source for the synthesis of CuO/Cu2O, to improve the technique efficiency and green status.

Controlling the content of inorganic constituents in solvents from industrial processes is necessary to monitor the process and meet the final product forecast. In this way, the calcination and digestion procedure assisted by microwave radiation was adequately offered for the determination of Fe, Cr and Ni in butyl acetate (butyl ethanoate – CAS 123-86-4) by plasma optical emission spectrometry. Inductively coupled (ICP OES). Recently, the Solvay Group found an opportunity to enter the pharmaceutical market by offering isopropyl alcohol (propan-2-ol – CAS 67-63-0), produced at the Paulínia plant, as an input for this segment. To meet this demand, a product sheet should contain a series of analyzes based on the methods of the American Pharmacopeia (USP, United States Pharmacopeia), including potential inorganic contaminants. In view of the above, a procedure was developed and validated for the determination of As, Cd, Co, Cr, Cu, Fe, Hg, Ni and Pb, which are some of the analytes that must be monitored in the isopropyl alcohol (propane-2) sample. -ol – CAS 67-63-0). To this end, alternatives for sample preparation and operational conditions for inductively coupled plasma optical emission spectrometry (ICP OES) determination were evaluated. Sample dilution in acidified aqueous medium and radiation microwave-assisted digestion were evaluated as sample preparation procedures. Regarding reliability methods, external reliability was evaluated based on an analytical curve in an acidified aqueous medium and the matrix compatibility method. The results obtained were statistically evaluated in relation to selectivity, linearity, accuracy and precision. The analytical methods presented included adequate linearity through the values of r and r2, the evaluation of residues and the homoscedasticity obtained for the majority of inorganic impurities in both proposed methods. The limit of detection and quantification of the curve meets the planned request (LOD < 0.1 mg L-1; LQ < 1.0 mg L-1).

The present thesis, "The young Machado de Assis and the rhetorical-poetic tradition in the first poems," offers analyses and interpretations of ten poems authored by the literary figure hailing from Rio de Janeiro, originally disseminated through the 19th-century periodical press. Since the colonial era in Brazil, knowledge of Rhetoric and Poetics, along with the practices of Eloquence and Oratory, especially the sacred one, circulated and flourished through manuals, treatises, and compendiums crafted by masters and scholars of the subject. Throughout the 19th century, virtually all Brazilian authors were, in some capacity, steeped in the disciplines of Rhetoric and Poetics, as evidenced by the enduring presence of these subjects in the curriculum of the Colégio Dom Pedro II, a standard educational institution in the country, for almost the entire imperial period. Thus, it is presented here an analytical reading aiming to elucidate how the principles, norms, and rhetorical-poetic values manifest in the composition of Machado's initial poems. To achieve this, a meticulous selection of poetic compositions has been made: “Soneto” à Ilma. Sra. D.P.J.A, “A saudade”, “O pão d’açúcar”, “O meu viver”, “Dormir no campo”, “Minha musa”, “Consummatum est!”, “Cognac!...”, “Álvares de Azevedo” e “Ao Carnaval de 1860”, published, the first, in “Periódico dos Pobres”, by Antônio Maximiano Morando, and, the others, in “Marmotas” by Francisco de Paula Brito.

Down syndrome is one of the most prevalent disabilities in the world's population. In this context, there is a set of specific demands regarding the possibilities of support both for people with the syndrome and for those who share their routine. This study seeks to understand the perception of professional librarians about the services and information products available to people with Down Syndrome, in libraries in the city of São Carlos, in the State of São Paulo, Brazil. As a method, opinion research in human sciences was used with an exploratory and cross- sectional character, through a data collection instrument developed for the research. The participants' answers were described by simple frequency of absolute number and for the open question of the questionnaire a qualitative analysis was performed with grouping in thematic categories. The results showed that the librarians interviewed did not have specific training to meet the informational demands of people with Down Syndrome, but they are interested in seeking information and training to improve their professional practice and promote social justice and accessibility. Their suggestions included the need for continuing education on the subject and raising awareness of the class in relation to the informational specificities of all audiences. This diversity of opinions and considerations highlights the importance of promoting debate and reflection on care for people with Down Syndrome in libraries. It is essential to invest in training, interprofessional partnerships and technological resources to offer an inclusive, accessible and quality service.

In order to seek a holistic understanding of the national territory, several initiatives that aim to expand and improve the mapping and control of Brazilian rural areas have been implemented by Brazilian government bodies, including the Rural Environmental Registry (CAR) and the Land Management System ( SIGEF) examples of systems developed for this purpose. Investigating the functionalities of the platforms and checking consistency between them is important to evaluate the efficiency of the initiatives and encourage integration between them. Using the municipality of Campina do Monte Alegre - SP as the object of study, the processes of obtaining environmental data by CAR and SIGEF can be applied, establishing a comparison between the data, in addition to evaluating the situation of the municipality in terms of its geographical characteristics. The results obtained showed that there is a certain overlap of areas declared in the CAR in the municipality of Campina do Monte Alegre, in addition to a significant number of properties not yet georeferenced according to the criteria of the property registration process in SIGEF. It is concluded that although the initiatives studied are very useful and efficient in several aspects for expanding knowledge of the national territory, improvements in the registration process are desirable, as well as actions to increase property owners' adherence to the systems and make the more agile process.
