We study the equisingularity of a family of function germs $\{f_t\colon(X_t,0)\to (\mathbb{C},0)\}$, where $\{(X_t,0)\}$ is a family of $d$-dimensional isolated determinantal singularity. We define the $(d-1)$th polar multiplicity of the fibers $X_t\cap f_t^{-1}(0)$, $m_{d-1}(X_t\cap f_t^{-1}(0),0)$, and we present results relating the constancy of $m_{k}(X_t\cap f_t^{-1}(0),0)$ for $k=0,\ldots,d-1$ and $m_i(X_t,0)$ for $i=0,\ldots,d$ with the constancy of the Milnor number of $f_t$ and the Whitney equisingularity of the families $\{(X_t\cap f_t^{-1}(0),0)\}$ and $\{f_t\colon(X_t,0)\to (\mathbb{C},0)\}$. In the particular case where $\{(X_t,0)\}$ is a family of isolated complete intersection singularity we provide a condition to ensure the Whitney conditions in terms of the integral closure of the ideal defining the singular set of each member of family $\{f_t\colon(X_t,0)\to (\mathbb{C},0)\}$. We also relate the constancy of the Milnor number of $f_t$ with the strict integral closure of the module formed by the partial derivatives of the application that defines $X_t\cap f_t^{-1}(0)$.

Degenerative and bones inflammatory problems represents almost half of chronic diseases developed on people older than 50 years old around the world, leading to problems of prolonged pain and physical limitation. Its prevalence increases with age and life style, therefore, with elderly population growth, these cases have been increasing too. These problems resolution, usually demand surgeries which involve implant and bone graft. Even with these therapeutic solution success, some inconvenient have been appearing, because of the fact implants are susceptible to infections, and because of grafts can lead to severe pain, local tissue death, and immunological rejection. Aiming to solve these limitations, Tissue engineering have appeared as an promising field of bone wound repair and reconstruction, through tridimensional porous matrix development, usually designated as scaffolds. Associated to these structures, are osteoprogenitors cells and growth factors, which lead to new bone tissue growth, through stimulation of ability of natural tissue regeneration of patient. Aiming this important clinical gap, the biomaterial Poly(L-co-D,L lactic acid- co-Trimethylene Carbonate) (PLDLA-TMC) presents advantageous features to the medical field, mainly when related to stem cells, due to immunemodeling activities of this cells. Therefore, in this essay it was seeding in a PLDLA-TMC 3D scaffold with different pores sizes (300 e 600 µm) for proliferation and ostegenic differentiation. In vivo assay were used 36 Wistar rats and were made a cranial bone defect with 8 mm diameter, separeted in 3 groups: negative control, group with PLDLA-TMC and group with PLDLA-TMC+MSC, in periods of 8 and 12 weeks. The results in vitro assay obtained for analysis by Laser Scanning Confocal Microscopy (LSCM) showed that PLDLA-TMC 3D scaffolds with 600 µm pore size, when compared the sacaffold of 300 µm pore size, favored the adherence and cell growth, and mainly, presented osteoinductive characteristic, which means that the material itself inducted cellular differentiation. The scaffolds implants of PLDLA-TMC with MSC, through histological and microCT analisys, showed better results in the period of 12 weeks, obtainning less inflammatory process and greater regeneration of bone tissue.

Industrial processes are increasingly requiring environmentally sustainable technologies and the use of enzymes is relevant due to the selectivity and specificity of these biocatalysts. However, the application of soluble enzymes in catalytic processes is often impracticable due to the high cost of these biocatalysts and the catalytic instability under severe physical-chemical process conditions. In this sense, the immobilization of enzymes guarantees the reuse of these biomolecules and often improves their stability. Among the supports used as immobilizing agents, nanoparticles have been increasingly studied due to the possibility of creating structures with high surface area to adsorb proteins and also to demonstrate low resistance to mass transfer, thus ensuring good accessibility of the catalyst to the substrate. Hydroxyapatite (HA) is a solid inorganic potential for immobilizing enzymes, since it is non-toxic, has good chemical and physical resistance, good ability to interact with proteins and can be synthesized in the form of nanoparticles; however, it has been little explored as a support for enzymatic immobilization. Given this context, the objective of this research was to evaluate the immobilization of the enzymes β-glucosidase, xylanase and phytase on hydroxyapatite nanoparticles (HA), as a strategy to improve the catalytic efficiency and stability of these enzymes. These enzymes have wide application in different sectors of the agribusiness, such as biofuels, food, animal feed and drugs. For this, HA nanoparticles were first characterized in order to understand their composition, size, morphology and surface area. Then, a systematic study of the immobilization of these enzymes in HA was carried out. The biochemical aspects of enzymatic immobilization were investigated, such as the physicochemical conditions of adsorption and desorption, that helps to understand the type of chemical interaction between support and enzyme. Changes in enzymatic activity profile, thermo-stability, conversion capacity during enzymatic hydrolysis and reuse of these biomolecules were also evaluated. The results obtained showed that the β-glucosidase, phytase and xylanase enzymes were efficiently immobilized on the HA nanoparticles using a simple and fast adsorption protocol, which occur mainly through coordination interactions between the Ca2+ sites of the HA with the carboxylic acids (COO-) of the enzyme amino acids. The biochemical behavior of the enzymes in the presence of HA was evaluated under different physicochemical conditions of adsorption and desorption (pH and ionic strength), indicating a strong and highly stable interaction between enzymes and support, with immobilization yields close to 100% and recovered activities in the range of 70-100%. For β-glucosidase it was possible to recycle the immobilized enzyme and retain 70% of the initial activity during at least 10 hydrolysis cycles. For phytase, the immobilized enzyme showed broader activity profile as to pH and temperature, and higher stability at high temperatures than free enzyme, whose improvement in its properties suggested the potential of applying the immobilized form of phytase in animal feed. For xylanase, the immobilized enzyme demonstrated greater affinity for the HA support that was modified with Cu2+ ions, promoting chelation interaction with enzyme amino acids, generating derivatives with maintenance of their catalytic activity and with activity profile similar to that of the free enzyme. Finally, the three enzymes were immobilized on HA magnetic nanoparticles (synthesized with cobalt ferrite, CoFe2O4), demonstrating excellent recovery capacity from the reaction medium through the application of a magnetic field. The results obtained showed the potential of HA to act as a support for enzyme immobilization, creating derivatives with promising industrial applications, which can improve processes and make them more sustainable.

In the cryptocurrency market, Bitcoin stands out as the most accepted traded in the world. However, due to its high volatility, the prediction of price behaviors, in special, the trend classification, becomes a challenge and valuable to investors. In this sense, in recent years, some studies have been proposed based on machine learning techniques to classify reliable trading signals from the Bitcoin return series. Thus, the present work explores Bitcoin's trend behaviors, seeking to classify its returns using high-frequency data from limit order book in terms of US dollar (BTCUSD) and euro (BTCEUR). The proposed methodology seeks to accurately predict returns, creating opportunities that better support trading strategies. Therefore, from the Bitcoin historical series, technical indicators (commonly used in financial markets), market variables and the own series of returns for different time intervals were extracted. It is worth mentioning that the data have a frequency of at most one second for each update of the entire order book, thus characterizing the high-frequency. Subsequently, these data are submitted to the inputs of trend classifiers based on Artificial Neural Networks and XGBoost, which were trained and validated in three months of trading, from January to March 2019, composing approximately 5 million market updates for each currency base. In a first analysis, the behaviors of the models for each base currency were observed, it is possible to note that the market for BTCUSD proves to be more efficient related to BTCEUR. Consequently, the machine learning models obtained more reliable and stable results over time for BTCUSD. Based on this initial result, sought to validate the predictive models for different training and validation configurations. In this second analysis, it was noted that the trend classification is more accurate for short intervals (between 1 and 3 minutes) in both base currencies, which is justified due to the high volatility in Bitcoin prices in short intervals. In a third analysis, it was observed that as we increased the number of training days for classifiers, in some cases, was noted a gradual loss in classification (between 1% and 2%). Still, in a fourth analysis, one-vs.-rest was applied to each trend behavior, there is a considerable performance increase in the classification in relation to the base case (between 1% and 7%)

Learning an oral language presents several challenges, two of which are: extracting words from continuous speech and mapping them to referents. Statistical cues (e.g., prosody, phonotactical probability) are an important source of information to overcome such challenges. Evidence suggests that the higher or lower probability of a syllable being followed by another one (transitional probability) can be indicative of word boundaries in continuous speech. Additionally, segmentation and mapping processes can occur sequentially and simultaneously as a result of tracking the co-occurrence between words and its referents. Nonetheless, there is still a limited number of studies investigating simultaneous processes of word segmentation based on transitional probability and mapping based on cooccurrences across ambiguous trials (when more than one word and one referent is presented). The present investigation aims to answer the following question: can words be simultaneously segmented from continuous speech and mapped to referents across ambiguous trials? Three studies were conducted to investigate this question. The first study, with nine experiments, investigated whether pseudowords (previously selected) could be extracted from continuous speech based on their transitional probability. Brazilian-Portuguese and English adult speakers participated. Results indicated that words can be segmented, but only when other statistical cues, such as the phonotactical probabilities, are controlled. The second study, with two experiments, investigated whether segmented words from the languages used in the first study could be mapped to abstract pictures during cross-situational word learning tasks. Brazilian-Portuguese adult speakers participated. Results suggest that words can be mapped and that performance improves when the task is repeated. Finally, the third study, with two experiments, investigated whether extraction and mapping over ambiguous trials can occur in parallel. Brazilian-Portuguese and English adult speakers participated. Results suggest that these processes can occur together, at the same time, and that accuracy rates in the parallel task are higher than accuracy rates in individual tasks (Studies 1 and 2). By combining transitional probability and the cooccurrence of stimuli across ambiguous trials, the present investigation helps to advance the current understanding of the role played by linguistic regularities in language learning. Additionally, this work inaugurated this line of investigation in Brazil, which can motivate future investigations of the topic.

This thesis is part of the range of recent studies of political and electoral development in Africa (since 2000), and seeks to highlight the simultaneous relationship between the role of political parties and voters in structuring an electoral democracy. It was in this context that this thesis aims to analyze the role of political parties in structuring the vote in Mozambique. Starting from the use of a methodology that complements the historical-institutional approach and the political culture, with the use of official electoral data, the most important results of the thesis, show that there is a tendency for political parties in Mozambique, after 20 years of the implementation of the democracy, structure the vote, through their areas of dominance and belonging. It is noteworthy that, in these areas (a. Gaza, Cabo Delgado, Maputo; b. Nampula, Sofala, Zambézia), since the period of the civil war, they have always been in favor of the Frelimo government and Renamo, respectively. Henceforth, despite a notoriety in terms of the structure of voting in Mozambique, there is an inverse tendency for the stability of abstention levels to grow from election to election in almost all areas of Mozambique, despite the increase in investment in socio-economic development programs, as public policies on education, health, improvements in HDI and GDP, did not reflect in the same proportionality with the increase in political and electoral engagement.

Various contaminants can affect the aquatic ecosystem and the organisms that live in it and can interfere with their physiological processes, as they accumulate in different tissues. Therefore, the evaluation of the effects of these contaminants on aquatic organisms contributes to the predictability of the action of different pollutants in this environment, generating information on mechanisms of adaptability to environmental stressors, as they are used as indicators of aquatic contamination. For this purpose, the experimental design consisted of exposing for 96 h bullfrog tadpoles, Lithobates catesbeianus, the water collected from two points (P1 and P2) of the Sorocaba River and in the dry (August and September) and rainy (March) periods. The following parameters were evaluated in the liver: protein concentration (metallothionein - MT, carbonyl proteins - PCO) and (lipid lipoperoxidation - OPL). In addition, the presence of metals, agrochemicals and drugs in the water and sediment at both points of the river were analyzed. In the analysis of water and sediment, the presence of agrochemicals and drugs was not detected; however, the presence of metals was verified at both points and in both periods. The presence of metals significantly increased MT and PCO in the liver of tadpoles exposed to water in P1 and P2 and in the rainy season, while in the dry period, the concentration of PCO and OLP significantly increased in the liver of tadpoles exposed to water from P1 and P2, respectively. These results indicate a picture of oxidative stress by the presence of metals in the water and suggests that these animals were able to alter the metabolic pathways for detoxification processes. Therefore, these results demonstrated that the proposed effect biomarkers can be good indicators of aquatic contamination in bullfrog tadpoles.

The accessibility for people with reduced mobility was researched in interface with tourism in the Itu Tourist City, in the State of São Paulo, aiming to verify the development in the treatment of the issue of accessibility in the context of historic centers and the feasibility of accessibility for people with reduced mobility in historical and cultural attractions. To achieve the objective of this research, an investigation was carried out with documentary survey and bibliographic review, in addition to the use of exploratory techniques. For this, a Check List was applied regarding the adequacy of space and enterprise to accessibility standards, present in the Manual of Technical Accessibility Instructions to Support the Architectural Project (SMPED, 2008) elaborated by the city of São Paulo with the objective of visualizing in a clearer and more aims at accessibility conditions, in addition to photographic records, including with the perspective of proposing possible improvements in the city’s Tourist Center. Special attention was given to attractions such as Cruzeiro de São Francisco, Casa Imperial (Casa Capelli), Fábrica São Luiz, 19th century Architectural Ensemble, Republican Museum, Church of Nossa Senhora da Candelária of the Itu Tourist City, in relation to accessibility for people with reduced mobility. Despite the enormous challenges posed to public and private institutions with regard to the application of accessibility norms and guidelines, nationally implemented and disseminated it is necessary to emphasize that there is ample research effort on the part of national and international teaching and research institutions international, in order to offer solutions that harmonize the confrontation of these challenges and the safeguarding of historical memories and the heritage of the communities. At the end of this work, it was concluded that accessibility for all is supported by a broad concept in Brazilian legislation, which seeks greater inclusion, giving an opportunity to participate in tourism, however, a large part of the laws are ignored or unknown from society, municipal administration and also by people with reduced mobility.

Among the factors that limit the full expression of the productive potential of sugarcane, the interference caused by the lack of weed control stands out. Thus, the objective of this work was to evaluate how the density and distance of Ipomoea nil and Digitaria horizontalis influence the development of pre-sprouted seedlings (MPB) of the sugarcane variety IAC SP 95-5000. The experimental design, for each weed species, was completely randomized (DIC) in a 4 x 5 + 1 factorial scheme, with four weed densities coexisting with MPB (1, 2, 4 and 8 plants, equivalent to 10 , 20, 40 and 80 plants m-2), five distances from the MPB (2, 6, 12, 18 and 24 cm) and a control without the weed, with four repetitions. MPBs were transplanted in 30 L pots and weeds were sown. After the flowering of the weeds, height, leaf area, dry biomass of the aerial part and nutritional analysis of the MPB leaf tissue were evaluated. The MPB furthest from D. horizontalis and I. nil showed greater development. Regarding the leaf area, higher values were found when the plants were 24 cm away from the weeds. The density and distance between D. horizontalis and Ipomoea nil in relation to MPB were affected by competition for macro and micronutrients, especially at higher weed densities.

This work proposes a critical analysis of the poem A máquina do mundo repensada, by Haroldo de Campos, published in 2000, composed in terza rima and structured in three cantos. The aim is to develop a reflection about the mystical and biblical elements present in Canto III, supported by literature theory, poetry criticism and the poet’s literary criticism, besides references about Kabbalah selected from the material available in the collection at Casa das Rosas: Centro de Referência Haroldo de Campos. The analysis starts from the hypothesis that the Aleph, letter and symbol from the jewish culture, is an image that moves rhizomatically in the poem, that is, it appears randomly along the poem. We intend to demonstrate with our reading that the alephic image dissimulates itself in other words, but it keeps exercising the symbolism inherent to the Aleph’s image. In this way, the objective of this work’s Chapter I is to recover the alephic images present in Canto III of the poem A máquina do mundo repensada (2004a). Chapter II aims to narrow the association between Haroldo de Campos and Kabbalah texts, circumscribing the work’s kabbalistic Universe. In order to do it, we focus on the analysis of the haroldian library books. The alephic nuclei located in Chapter I and the kabbalistic themes discussed in Chapter II guide the reading performed in Chapter III, in which Canto III of the poem A máquina do mundo repensada (2004a) is extensively analysed through Kabbalah bias. This analysis takes into consideration the theoretical apparatus of texts about Kabbalah and by Walter Benjamin (Infância berlinense: 1900 (2017) and Sobre o conceito de história (1987). Benjamin’s texts allow us to think about the relation between the poetic persona and the tradition, focusing on the Kabbalah tradition mobilized in the studied Canto.

This research is carried out within the scope of the French discourse analysis (according to the discipline's current guidelines, discussed, among others, in MAINGUENEAU, 2015) about the term “transparency”, which we hypothesized to be a discursive formula for meeting, in its current circulation , to the properties proposed by the theory of Krieg-Planque (2010), which are: to be a crystallized formal structure, to function in a discursive dimension, to have a controversial character and to establish itself as a social referent. The theme investigated in the research is important for understanding part of the current political situation, as it materializes in different social groups, considering that, in the data observed preliminarily, “transparency” is often placed as a condition for the functioning institutions. The survey of the occurrences of the term and its variants (such as, for example, “transparent”) occurs through the notion of route (MAINGUENEAU, 2015). The collection of occurrences is made from the Google applications (Google Search, Google Trends, Google Alerts), from the DuckDuckGo search engine, in three different internet protocols (IPs) and disconnected from Google accounts, in order to diversify the results, avoiding the personal device bias. The analysis of the senses mobilized by the social actors to understand the discursive dimension and the controversial dimension of the formula, and thus turn to the circulation of that expression, in order to understand a little of the practices that crystallize and, at the same time, are instituted by she. In addition, the discursive functioning of power relations that permeate these practices is explored. That is, the disputes for meaning between institutions and subjects, which occur in a given public space and at a given time, the way in which subjectivities adapted to the production and acceptance of neoliberal politics and economics are produced. The research concludes that this formula works as a supposed cure for corruption, therefore it has a positive, desirable and unquestionable value, at the same time that it is a vector of demonization of what is not transparent.

Programmed cell death may have important intra and inter-specifics effects in phytoplanktonic populations, and consequently in the ecology of freshwater ecosystems. However, before any ecological studies or evolutionary interpretations, it is essential to document the phenotypic changes associated with PCD since the morphotypes and markers may be different in the same organism in response to different environmental stimuli, implying in different ecology evolutionary interpretations. Moreover, these interpretations can also be conflicting due to incorrect application and interpretation of the measures and markers of PCD. Thus, in Chapter 1, we presented a systematic review of the different methods and measures of PCD, and offered suggestions as how PCD should be measured in eukaryotic phytoplankton. Additionally, in chapter 2 we provided a first-time report of PCD in Ankistrodesmus densus, a member of the important microalgal group of the family Selenastraceae (Chlorophyta, Chlorophyceae, Sphaeropleales). Based on our revision, transmission electron microscopy (TEM) appears essential, as the first approach, for properly detecting PCD. Ultrastructural images should be compared and complemented with biochemical and genetic assays. In order of preference, we suggested DNA laddering and PS externalization. Biochemical markers such as caspase activity and the increase in reactive oxygen species (ROS) should be used with caution since these are not specific enough for PCD. Therefore, we have used ultrastructural morphological changes, PS externalization and DNA laddering to document PCD in A. densus in response to darkness, nitrogen starvation, and heat and cold shock. Our findings suggest that light and nitrogen deprivation may lead to a small but significant fraction of community to undergo PCD. On the other hand, we also present evidence that different death morphotypes can emerge in A. densus depending on different environmental inducers, which is essential for the interpretation of the results of ecological studies. Moreover, our results indicate that the vacuolar/autophagic like cell death morphotype existed in single-celled green microalgae (Chlorophyta) before land plants evolved and might have been an important development for tissue homeostasis in higher multicellular plants.

Materials Management is the set of activities developed by an organization in order to supply the users' needs with the materials necessary for the normal performance of their respective duties, thus avoiding losses to the parties involved. In this context, the present study aims to analyze the activities developed in the Warehouse Department - DeAlm, which corresponds to a Central warehouse of the Universidade Federal de São Carlos - UFSCar, located in the São Carlos campus, responsible for the supply of materials, and related activities, for all units, administrative or academic at the São Carlos campus, as well as the campi de Araras and Lagoa do Sino, and, eventually, for the Sorocaba campus. Through the use of process management, an analysis of the current situation of the processes carried out by DeAlm was developed in order to develop proposals for improvements to it, and, in particular, for aspects related to demand management and stock management. The research methodology used to carry out this work was a research of a descriptive and exploratory nature, where, through the case study, information was collected on the DeAlm structure, its processes, its stocks and the control of existing information. In addition to this information survey, other bibliographic or legislation sources were considered. Through the analysis of the mapping of the current situation of the studied processes, twelve proposals for improvements related to demand and stock management and to the service of customers using the DeAlm services were identified. The proposals prepared seek to improve the stock control system, avoid stockouts, implement performance indicators that can assist in the planning, execution and control of the activities carried out by DeAlm. In addition, the proposals seek to reduce uncertainties and build a reliable record history for checking and choosing demand forecasting methods that best adapt to the reality of DeAlm users, in addition to assisting DeAlm customers in executing their orders and planning both to perform and to receive their orders, thus preventing the units from having their routine activities hampered by the lack of material.

Coparenting is a term used to refer to how parents (or other parental figures) interact, when deciding how to handle their parenting roles. The coparental relationship has important effects on children’s development and the well-being of parents. The Coparenting Relationship Scale, an instrument developed to evaluate coparenting, has already undergone a cross-cultural adaptation process for use in Brazil, where it is called the Escala da Relação Coparental (ERC). The objective of the present study was to look for evidence, based on theoretical concepts of accuracy and validity of the ERC, based on its internal structure (using confirmatory factor analysis and tests for invariance) and association with external variables (to examine discriminant validity and correlations with tests that evaluate related constructs). Data were collected with 433 parents (238 mothers and 195 fathers) who had at least one child of up to 6 years of age. In addition to the ERC, instruments were applied to evaluate the relationships among ERC scores and measures of: (a) social desirability (to examine discriminant validity), (b) child adjustment, (c) marital satisfaction, (d) depression, (e) parental stress, and (f) social skills. Based on a confirmatory factor analysis, the internal structure of the Brazilian ERC included the same six factors that had satisfactory levels of reliability, and that formed the original American structure. In addition, there was evidence for invariance of the structure of the instrument, in relation to gender, at the configural, metric and scalar levels. With respect to accuracy, all ERC subscales presented values considered to be acceptable or satisfactory. With respect to evidence of discriminant validity, statistically significant correlations were found between only two ERC factors (undermining and conflict) and the total score of the social desirability instrument, and only for fathers. With respect to marital status and depression, most of the correlations were significant, which supports the study hypotheses. For child adjustment and parental stress, a significant number of correlations was observed, but for social skills, most of the correlations were not significant and these results differed from the study hypotheses. In addition, some correlations between the ERC subscales and the social skills instrument, although significant, were in the opposite direction than was expected, for the mothers. These results provide substantial evidence for the accuracy and validity of the ERC, besides confirming theoretical concepts about variables associated with the coparenting relationship. However, two limitations of the study were the low number of participants who responded to each of the instruments (with the exception of the ERC) and the low variability of responses for some of the constructs being evaluated, making it difficult to verify the existence of the expected correlations. Finally, it is noteworthy that the development of a brazilian instrument to evaluate coparenting, that has satisfactory evidence of accuracy and validity, may be useful in the context of scientific research as well as in intervention settings.

Sexuality education is a controversial topic and, at the same time, it is considered a taboo by society. Systematically, the theme has been discussed in different ways and nomenclatures by the public authorities, by social movements and media and in formal, non-formal and informal spaces, when talking about education. The objective of this research was to understand what are the teachers' perceptions about gender, sexuality and their relations in Science Teaching in a public elementary school II and how these perceptions interfere in the approach of this theme in the classroom. We carried out a case study and the tools used to carry out the research were: semi-structured interviews with school teachers; analysis of the School's Pedagogical Political Project (PPP) and the textbook used; analysis of didactic sequences that dealt with the topic directly or indirectly. We use Discursive Textual Analysis (DTA) as an interpretative and analytical tool for the data collected, since this work aimed to deepen the understanding of the investigated phenomena from a rigorous and judicious analysis. After the transcripts of the interviews and the unification of the speeches, we arrived at two categories: aspects of the teaching profession and aspects related to the content. The research showed that the teachers interviewed did not have specific discussions about sexuality and gender in initial and continuing education. According to the interviewees, they discuss in class what is geared towards anatomy and physiology, that is, characteristics, organ functioning, reproduction and STIs. However, the literature indicates the need for training that is guided by an understanding in which sexuality is worked in a way that goes beyond biological determinism, thus, it is possible to open spaces for discussions about sexuality in the cultural and social field, understanding gender inequalities in order to combat discrimination and violence.

One of the topics of great importance for current education is the inclusion of pupils with disabilities and / or special educational needs (SENs), and we must analyze how this process has taken place. Relevant factor for the analysis is the guarantee of enrollment to this portion of students established in our legislations since the Federal Constitution of 1988. The enrollments of these students in regular spaces of schooling have as one of their main challenges the training of teachers to act with the diversity of the student. Thus, this research aimed to analyze the social indicators of the school census on the formation and profile of teachers in the area of Sciences, graduated in degrees in Physics, Chemistry and Biological Sciences, in view of the assumptions of inclusive education. In order to meet this objective, the microdata of the school census was analyzed, considering the information about the initial and continuous training area of these teachers in the perspective of inclusive education. The microdata from the years 2007 to 2017 were analyzed through historical-dialectical materialism, and their discussion was based on the theoretical framework linked to Historical-Critical Pedagogy and Historical-Cultural Theory. The results of this research reveal that there is a very small number of teachers working in the public network who have in their main education subjects focused on attending the SEN or the Brazilian Sign Language (LIBRAS), as well as teachers who have continuing education in Special Education, which did not exceed 0.39% in 2017. Moreover, the analysis of microdata when dealing with teacher hiring shows that precarious and temporary hiring bonds are becoming increasingly naturalized, contributing to greater challenges in the school environment. This research recognizes that although data collection for the school census finds weaknesses, these do not diminish the importance of research that focuses on microdata, since they guide new policies and actions in education, including financing proposals. It is essential, therefore, to know the limitations of the school census database, but at the same time to study it, as it allows us to draw both an overview of enrollments of students with disabilities and / or SEN over the years, how much to understand the characteristics of formation basic education teachers.

With the growth of the world population and the consequent increase in demand for food, the agricultural sector will be impacted, resulting in greater consumption of water and nutrients to meet the demands of agricultural crops. Thus, the use of treated domestic sewage can be an alternative to ensure the use of nutrients and promote the rationalization and conservation of water bodies. This study aimed to compare the production, quality and nutritional status of strawberries grown in a hydroponic system using conventional nutrient solution and treated domestic sewage, seeking savings in the use of fertilizers. The experiment was carried out in an agricultural greenhouse in an NFT hydroponic system (Nutrient Laminar Flow Technique) with three treatments: (TA) consisting of drinking water and chemical fertilizers, (TRA) reused water supplemented with chemical fertilizers and (TR) drinking water. reused. Each treatment consisted of four cultivation benches, a motor pump system, timer and 500 L container for storage of nutrient solution. In each bench, four hydroponic profiles with capacity for 12 plants were used, totaling 48 plants per bench and 192 per treatment. The benches were divided into four randomized blocks. The nutrient content of the reused water was compared to the conventional nutrient solution, the amount of nutrients used in the treatments, the microbiological quality of the fruits, the nutritional status of the plants and the quantitative and qualitative aspects of the fruits. The TR treatment showed a significant difference when compared to the others, with visual symptoms of nutritional deficiency in the plants, lower productivity, more acidic fruits and smaller diameter. The content of soluble solids was not altered by the treatments, as well as the microbiological quality of the fruits, which did not indicate the presence of Escherichia coli. The use of reused water to compose the nutrient solution made it possible to obtain savings of 33% in chemical fertilizers in the TRA treatment, compared to TA. The reused water when supplemented meets all the parameters of the strawberry culture, being equivalent to the cultivation with conventional nutrient solution.

This study aimed to evaluate the air filtration performance of the fiber layer, produced by centrifugal spinning equipment, adhered to the surface of a commercial filter media applied to the internal ventilation system. Also, to investigate the antimicrobial effect of the thyme essential oil added to the fiber layer for Escherichia coli and Staphylococcus aureus. For this purpose, filter media were produced varying the operating conditions of the equipment, the type of solvent and the substrate. The characteristics of the fiber layer (fiber diameter, porosity, pore size), filtration performance (pressure drop, permeability and collection efficiency of nano and microparticles) and the biocidal effect were analyzed. It was found that the combination of the use of VCS and substrates with different permeabilities led to the formation of a fiber layer with different characteristics; the more permeable the substrates, the lower the porosity of the formed fiber layer. The increase in the power of the VCS promoted an increase in production of fibers, with the decrease in the size of the fibers and the porosity of the fiber layer, consequently, increase in the pressure drop; the collection time had a strong effect on the fiber diameter, in which the longer collection time increased the fiber diameter. The addition of the fiber layer decreased the permeability of the filter medium, increased the pressure drop and the collection efficiency. The investigation of the substrate covered by PAN fibers produced from solutions with dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) indicated that the filter media DMF and DMSO had similar collection efficiency. This may indicate that the DMSO solvent promoted stronger and more consistent polarization of the PAN chains than the DMF solvent, increasing the collection of particles from the DMSO filter medium. The DMSO filter medium was expected to have less collection efficiency than DMF because the DMSO filter medium had a smaller fiber diameter and pore size than DMF and values close to surface porosity. In the study of the filtration performance of pure substrate and substrate covered by PAN fibers, the collection efficiency of micro and nanoparticles was evaluated. For the collection efficiency of nanoparticles, the collection efficiency had an increase of about 20% with the addition of PAN fibers. For the collection efficiency of microparticles, at the beginning of the experiment, the substrate showed a collection efficiency of 50.5% and the covered substrate of 71.0%. After 30 minutes of filtration, the substrate remains in deep filtration, while the addition of the fiber layer promoted surface filtration, which significantly increased the collection efficiency to 97.2%. Finally, the fibers were spun in the same operating conditions on the substrate with essential thyme oil. The filter medium was named 5THY when the thyme essential oil was added to the PAN solution and THY when the essential oil of thyme was sprayed on the filter medium after the production of the fiber layer. The filter media covered with fibers showed a greater pressure drop and collection efficiency of micro and nanoparticles and less permeability than the substrate. THY showed higher collection efficiency than the substrate and 5THY, 99% for microparticles and 58% for nanoparticles. Through the antimicrobial test, it was found that THY showed a 99.999% reduction for the bacteria Escherichia coli and Staphylococcus aureus. While 5THY had a reduction of 15.5 and 89.0%, respectively. In the 5THY filter, the essential oil was added to the fibers before spinning, this may have caused the trapping and/or evaporation of the essential oil and, thus, reduced the reduction of bacteria.

Nowhere else in the itinerary of Being and Time (1927) does Heidegger explicitly problematize the status of the nothing inherent in the structure of being of human existence when, from the notion of nullity, he recognizes in § 58 the unfounded (finite) character of Dasein. Regarding the clarification of nothingness, negativity (Nichtheit), latent in the existential structure of nullity, as an index of finitude, the ultimate meaning and significance of both are left, in Being and Time, as a task to be accomplished. Based on this diagnosis, this thesis proposes to investigate the ontological-metaphysical meaning of the phenomenon of nothingness, starting from the hypothesis that the problem can be taken as a guiding thread to understand a significant part of Heidegger's investigative path, mainly the path that extends from 1912 to 1939. It is intended to maintain that such a conducting thread has a fundamental and systematic character, insofar as, to be elucidated, it demands the determination of the status of the relationship between ontology, metaphysics and logic in the Heideggerian thought itinerary. Thus, far from being, at first sight, a circumstantial concern regarding the leitmotiv of Heidegger's thought, Seinsfrage, the question of nothingness and finitude would be central to the development, subsequent to the publication of SZ, of his metaphysics project. As a consequence, in raising the problem of the origin of negation, the concept of nothing would allow to establish the place occupied by logic itself within ontology and metaphysics. It is precisely the problem of the sense of nothingness that, in his historical-deconstructive record, allows Heidegger's critical confrontation (Auseinandersetzung) with Hegel, since, as an essential theme, negativity is investigated both in the Hegelian system, which represents the consummation of the history of Western metaphysics, as well as the history of metaphysics in general. In this sense, in spite of Heidegger's thematization of nothingness as a finiteness of being apparently opposed to the infinite power of negativity in the Hegelian logical-metaphysical system, we intend to maintain that there is a deep affinity between Hegel's and Heidegger's positions. If this hypothesis of an assumption common to both is correct, it will be possible not only to understand the scope of the problem opened by the concept of nothing in the Heideggerian Denkweg, but also to open a perspective, not explained by Heidegger, to thematize the very origin of nothing from its anthropogenic character.
