Nowadays, the technique of direct sowing has been recognized as the most viable and economical alternative in large-scale restoration. Thus, the objectives of the work were to analyze how direct sowing methods provided diversity and density of species and how this affected the assembly of plants in order to indicate potential or suitable species for direct sowing. The study areas are located in Anhembi-SP inserted in zones of Seasonal Forest, where eight treatments were tested evaluating the soil preparation (harrowing or subsoiling), the seeds distribution (manual or mechanized) and the density of sowing (125,000 to 250,000 seeds.ha-1 with 64 species, in different combinations during the critical emergency period from 30 - 150 days after sowing. The harrowed area with manual sowing and 250,000 seeds. ha-1 (1B) was the one with the highest plant density (13,400 ind.ha-1) but the area with subsoiling, manual seeding and sown with 125,000 seeds.ha-1 (5C / 50%) obtained the higher richness (S = 17) and diversity (H '= 2.42) of species, but with a low density (5.200 ind.ha-1). . The higher richness was from the Fabaceae family (11 species), followed by the Malvaceae (4 species), Anacardiaceae and Bignoniaceae (3 species). The species Mimosa bimucronata (DC.) Kuntze (0,092 ind.m²) Mabea fistulifera Mart. (0,074 ind.m²), Bixa orellana L. (0,065 ind.m²) and Anacardium occidentale L. (0,043 ind.m²) showed the highest densities between treatments. The study of the species assemblage in its initial trajectory allowed to evaluate the factors that influence the potential of species establishment and showed the importance of species composition, soil preparation and seed distribution in emergence and initial density in direct sowing.

This master’s dissertation is divided into two parts: the first part is composed by summary of this work with less technical language, written in Portuguese. The second part is composed by manuscript for publication, in English language. The literature has shown that associating eating-related words (CS) with valanced words (US) may differentially influence affective-motivational and top-down evaluation systems. We tested this claim in a subliminal CS-US conditioning procedure, where CS and US were respectively presented for ~17 and 170 milliseconds respectively. Three groups of Brazilian undergraduates (N = 69) viewed eating-related words (CS+) or their scrambled counterparts (CS-) followed by positive or neutral words (US). A free-selection visibility check confirmed that none of the subliminally presented CS had been reliably detected during conditioning. Participants who associated CS with positive US produced reliably more saliva than remaining groups, whereas CS evaluations were not significantly influenced along explicit or implicit evaluation levels. Reliable saliva augmentation, coupled with non-significant evaluation outcomes, illustrates how affective (CS-US) information can credibly influence motivational response systems even as top-down evaluations appear statistically unaffected.

Didactic games stimulate several areas of the brain circuits, from the interpretation of images such as the storage and improvement of vocabulary to strategies in relation to the specific theme addressed by the game. It is worth mentioning the importance of the social interaction that the games bring among its participants and once they are chosen and applied as a pedagogical resource, they often end up being satisfactory for learning a certain content outside or inside the classroom. However, in pandemic times, WHO recommends social distance and remote classes to meet the needs of students during the 2020 school year. Thus, we tried to transform the physical game into digital format and faced some difficulties due to lack of resources and understanding of computer graphics. In this way, the present work aims to verify how basic education teachers are dealing with these situations at this moment, and what are their understandings regarding virtual didactic games. And we conclude that although teachers use and think they are a good helper in teaching and learning students, there is still a need for projects involving both technology professionals and specific teachers in the field in order to develop better games that include fun and motivating specific content.

The Paired-cell Overlapping Loops of Cards with Authorization (POLCA) is the Production Control System (PCS) that Quick Response Manufacturing (QRM) suggests for high variety and low volume. However, the suggested environment commonly describes the Make-to-order (MTO), which requires a PCS to control many routings of jobs, as the General Flow Shop (GFS) describes, and high variable lead times for each process. In those conditions, releasing orders by authorisation lists have presented some problems to deal with that time variability. One solution has been using alternatives PCSs as Control of Balance by Card-Based Navigation (COBACABANA). Another solution to that problem is that POLCA has incorporated other complements in the order release mechanism, as the Release-and-Flow POLCA (RF-POLCA), the Advanced Resource Planning and the COBA-POLCA. Nevertheless, those complements do not take advantage of the original concept of POLCA: the paired-cell overlapping loops. Therefore, this research proposes an order release mechanism based on the indirect load of a shop for POLCA, called IL-POLC, that uses the paired-cells loops to aggregate the indirect load. For that proposition, this research uses a systematic literature review to identify factors that influence how the PCSs work in the cited environment. Then, the research presents two simulation experiments to compare the IL-POLC proposed. The first experiment compares IL-POLC with the original POLCA and RF-POLCA, detailing specific factors for POLCA parametrisation. The second experiment compares IL-POLC with COBACABANA and COBA-POLCA. As a result of the literature review, this research presents a framework to describe how each factor influences the task of the PCSs. This framework was used to define factors in the experiments. The proposed IL-POLC shows that releasing jobs by indirect load conditions is better than the original order release of POLCA and RF-POLCA that uses the authorisation lists by release dates. IL-POLC solves the variability of lead times by the indirect load condition on the order release mechanism. According to the second experiment, IL-POLC is better than the other two PCSs when the shop uses the card-based version and a proportional representation of the card for the amount of work of each job. IL-POLC do not reduce the Shop Floor Throughput Time as the other systems, but it does not deteriorate the other performance measures. According to the results, the experiment suggests using IL-POLC in shops that it is challenging to estimate workload norms for the centralised release. Future research is suggested to confirm how the adapted order release reacts with external factors such as cell availability, labour interchangeability, and test in other scenarios as practical implementations to confirm these results.

Study 1: Aim: to investigate, through the NIRS, the acute effects of PBMT by light emitting diode (LED) on the oxygen delivery and utilization in humans. Methods: Twelve healthy young participants were treated with a LED device (850 nm, 50 mW, 2 J) and sham applied over the proximal third of the flexor carpi ulnaris muscle of the left or right forearm selected in a random order. The LED was applied in direct contact with skin and the device was switched on for 40 s in 4 different interventions (I1, I2, I3 and I4) with a 3-minute interval between interventions. The sham condition was considered as the period before the first PBMT. The NIRS device was used to evaluate the relative changes in [O2Hb] and [HHb] before and after sham and interventions. Results: We found that PBMT statistically increased the [O2Hb] in 0.39 μM. Conclusion: These results demonstrate the potential of PBMT to increase oxygen availability. Study 2: Aim: The main purpose of this study was to verify the acute dose-response effect of PBMT by light emitting diodes (LEDs) on hemodynamic and metabolic responses in individuals with type 2 diabetes mellitus (T2DM). Methods: Thirteen participants with T2DM (age 52.6 ± 7.3 years) received PBMT by a light-emitting diode array (50 GaAIAs LEDs, 850 nm, 75 mW per diode) on the rectus and oblique abdomen, quadriceps femoris, triceps surae, and hamstrings muscle areas, bilaterally, using different energies treatments (sham, 75, 150, 300, 450 and 600 Joules - J) in random order with a wash out of at least 15 days apart. On the day of the experimental protocol, the subjects were placed at rest, to perform the first blood sample collection from the right ear lobe through a heparinized capillary, for later analysis of blood glucose and blood lactate levels. After 5 minutes of rest, PBMT (effective or sham) was applied, and a second blood sample was collected 1 minute after TFBM irradiation. Finally, 15 minutes after TFBM irradiation, the third blood collection was performed. Results: The TPBM by LEDs statistically decreased blood glucose levels in the 15 minutes after application of the 75 and 450 J irradiation protocol; reduced blood lactate levels 15 minutes after application of the 75, 450 and 600 J irradiation protocol; increased cardiac output (Q) and cardiac index (CI) in the 1st minute after application of the 75 and 300 J irradiation protocol; and reduced Q and HR in the 15 minutes after application of the 300 J and 600 J irradiation protocol, respectively. Conclusion: In conclusion, for positive modifications on hemodynamic variables, the ideal therapeutic window was the range from 75 to 300 J, whereas for the metabolic variables was from 450 to 600 J, with a power output of the 75 mW per diode LED. Study 3: Aim: The main purpose of this study was to evaluate the acute dose-response effects of TPBM associated with moderate intensity exercise, consisting of a constant load protocol (CL) followed by a binary pseudo random protocol (PRBS), in hemodynamic responses and cardiorespiratory adjustments in subjects with type 2 diabetes mellitus (T2DM). Methods: Thirteen men with T2DM (age 52.6 ± 7.3 years) received PBMT by a light-emitting diode array (50 GaAIAs LEDs, 850 nm, 75 mW per diode) on the rectus and oblique abdomen, quadriceps femoris, triceps surae, and hamstrings muscle areas, bilaterally, using different energies densities (sham, 75, 150, 300, 450 and 600 Joules - J) in random order with a washout of at least 15 days apart. After the application of TPBM, the volunteers were submitted to a CL followed by a PRBS. After the TFBM, the volunteers were submitted to an exercise protocol in cycle ergometer, consisting of a free load warm-up for 3 minutes and a CL, for a period of 6 minutes, performed at 80% of the ventilatory anaerobic threshold (VAT), achieved in a previous cardiopulmonary exercise test, and followed by a binary pseudorandom protocol (PRBS), for a time of 17 minutes and 30 seconds, with load stages that ranged from 20 to 80% of the VAT. Results: We found that TPBM enhanced the improvement of the dynamics (MNG) of Q with the energy of 600 J (p = 0.014). Conclusion: In conclusion, our findings showed that TFBM, previously applied to physical exercise, and in different energy densities, does not promote improvement in most cardiovascular and ventilatory responses. General conclusions of the study: The findings of this thesis allow us to conclude that: (1) PBMT applied in healthy young people is able to improve muscle tissue oxygenation; (2) PBMT applied in isolation, enhances the metabolic and hemodynamic responses at rest in the diabetic population, and (3) PBMT applied previously to an exercise protocol of moderate intensity and duration of 23 min, does not promotes distinct effects from the sham application in the hemodynamic variables and in the dynamics of the VO2.

According to the literature, the advent of the Internet and virtual social networks have increasingly crossed the daily lives of individuals in general, especially adolescents and, although it already have points to indications of the existence of a relationship between technological modernity, its fruits and the psychosocial development of adolescents, studies that delve into this theme are incipient. Therefore, the objective of the present study was to identify and analyze, by means of a scoping review, studies and reports published in national and international journals that relate adolescent mental health and Internet use. For the project proposal, an active search was carried out in the databases Scopus, Web Of Science and the Virtual Health Library (VHL), using the descriptors: adolesc*, teenage*, young*, social networks, internet, online, mental health and mental suffering, with specific inclusion and exclusion criteria that selected thirty-four articles for the final sample. The treatment and analysis of the results obtained were based on the steps proposed by the Joanna Briggs-JBI Institute for scope reviews and after the analysis of all productions, the results were organized into four distinct thematic categories: 1) Harmful and indiscriminate use of digital social networks; 2) Violence in the virtual environment - Cyberbullying and Cyber Vandalism; 3) The internet as a means of exposure of mental suffering and 4) The internet as a means/space of exposure of mental suffering. It was possible to conclude that little was produced in the national literature, being the international literature the great base for the study. It was found that the adolescent public has become the central target of the reach of the virtual world, and that this generates a direct impact on their daily life, behavior, and relationships, which may cause or aggravate psychological and emotional problems. It was also possible to verify that there is a predominance of the female gender in the harmful use of social networks, and that the virtual environment, as a powerful influencing link, may open a path for the development of early intervention strategies and mental health promotion, as there seems to be a greater tendency related to the exposure of feelings on the internet. This theme has gained strength in recent years, highlighting the growing problem and the need for new productions.

This research aims to problematize the composition operated by the Mathematical Modeling discourse about reality within the scope of published researches concerning Mathematical Modeling. In this work, Mathematical Modeling is conceived as a discourse, using as a theoretical-methodological basis the theories of the philosopher Michel Foucault and his commentators. The research was constituted, at first, called trail 1, by the congress proceedings of the National Conference on Mathematical Modeling and the International Research Seminar in Mathematical Education, both in the period from 2003 to 2018 and, later, called trail 2, by fifteen works published that discuss, exclusively, the relationship between Modeling and reality. Through the analysis of the congress proceedings, it was possible to map the following statements: Modeling, through mathematical models, represents reality; Modeling, through the mathematical language, allows the student to understand reality and Modeling, through the mathematical language, allows the student to understand, intervene and transform the reality that surrounds him. The statements show different behaviors regarding reality, however, they all build the same composition on the real, that is, the one to be modeled by the curricular mathematical contents, which produce ways of acting and thinking about the subjects and reverberating ideals of Modernity. In the second moment, when analyzing works involving Modeling and reality, the approximation with the philosophical discourses: Classic, Modern and Contemporary was mapped in the construction of this relationship. Through these analyzes it is possible to affirm that the relationship between Modeling and the reality close to the Classic philosophical discourse builds the vision of a reality that has an essence; in Modern philosophical discourse, he conceives the view that reality will be elaborated with the subject; and in Contemporary philosophical discourse, reality is constructed based on language. The analyzes made suggest that the construction of the reality operated by the Modeling discourse can be seen as a resource to continue operating the teaching of Mathematics based on the vision of knowledge as a reliable representative of reality.

This thesis proposes a semiotic look at the cinematographic language, aiming at a more accurate description of the expressive visual elements at play in the process of meaning not only of the films, but, above all, of the different audiovisual genres that use the same cinematographic code for their manifestation. Our theoretical framework starts from the semiotics of French tradition - including its tensive proposal, which, certainly, does not disregard the premises that support this broad theoretical project - in addition to cinema studies. The first part of this work is reserved for the formulation of analytical bases on the cinematographic language, and begins with the survey and reflection on studies that bring cinema and linguistics together, through key concepts for this, as value, syntagm, paradigm, sign, text, system, code and language. With that, we outlined guidelines for the observation of cinema, whose code is built by the syncretism between the photographic, musical and linguistic codes, culminating in an analytical perspective from the approaches of Waldir Beividas, Claude Zilberberg and Jacques Fontanille. The second part proposes to test the effectiveness of what we have been building, starting from the analysis of an object of study: the film The Crow (1994), chosen due to the sensitivity with which it mobilizes the photographic code, creating peculiar and contributing to the flow of the text, which highlights the continuous movements of interdependence between the content plane, which does not dispense with the gradations of the expression plane.

Known as the world's largest producer of crystallized sucrose, Brazil has been investing and increasing production capacities as well as seeking for greater energy efficiency and modernization of its sugar factories. In this context, continuous crystallization processes are replacing the traditional batch vacuum pans. This work aims to model, simulate and analyze a continuous vacuum pan (CVP) of B Massecuite, by solving its mass, energy and population balances and applying kinetic models from literature. The studied CVP is a horizontal equipment of vertical tubes with twelve compartments operating under vacuum, which is similar to the equipment applied in São Martinho sugar production industry located in São Paulo state. In this way, an analysis of the industrial data was performed to define the main factors that influence the production of B Massecuite, as well as investigating the size distribution and crystal characteristics of crystal produced in each compartiment. Then, two stationary models were developed and compared for the continuous vacuum pan. The first model (Model 1) comprises CVP as a set of perfectly agitated tanks in series, while Model 2 assumes the equipment as a plug flow crystallizer. The mass, energy and population balances of the two models were performed using Microsoft Excel software applying the VBA (Visual Basic for Applications) language and a set of entry data provided by São Martinho. The results of mass and energy balance calculated via the two models were compared with the experimental B Molasses purity, while trying to adjust the population balance using experimental data from the industrial equipment, such as crystal content and average size from each one of the 12 compartments. The adjusted models were validated using a set of real data, being verified the ability to simulate the operation of the studied continuous vacuum pan and the choice by Model 2 was made, with adjusted parameters to best represent the crystal content and average size inside the equipment. The typical operating conditions of Brazilian raw sugar industries were simulated in order to understand the influence of the raw material purity on the CVP performance. The contribution of the brix value set for each compartment for productivity and quality of B Massecuite was studied and an optimal total brix curve was selected to increase production without compromising the sugar quality. Finally, a brief analysis on the operation of only one side of the CVP was performed in comparison with the operation of the 12 compartments with a lower production.

The cutting tool manufacturing industry constantly seeks to improve its products, due to the high competition in this sector. In this scenario, cemented tungsten carbide cutting inserts stand out for their wide application, related to their excellent cost-benefit ratio in the machining of diverse types of metals. Thus, an increasing knowledge of their manufacturing process variables and their effects is required, being the grinding operation a fundamental step in the search for high efficiency of cutting inserts, as it is responsible for providing the final dimensions as well as appropriate surface and edge quality. Within this context, the present work aims to characterize the wear of a diamond grinding wheel during grinding of cemented tungsten carbide inserts and to assess its effects on the insert surface characteristics with the increase in total material removal volume. For this, a resin bonded wheel with diamond grains D46 was applied and the normal and tangential force components were measured during the process. In addition, the grain protrusion in the abrasive grinding layer, the insert surface and edge roughness were analyzed. The obtained results revealed an initial reduction in the grain protrusion and the consequent increase in the grinding forces with the increase in the volume of removed material. With the grinding of larger volumes, however, the occurrence of self-sharpening was also observed, which led to increased grain protrusion and reduced forces. This phenomenon contributed to the increase in the number of active edges in the abrasive layer and caused a reduction in the insert surface roughness. Little or no variation in edge roughness was identified.

The objective of this work was to develop metal complexes containing natural products that have antioxidant activity to be applied in the cosmetics sector. For that, 3 [Mg(phen)2PN]+ metal complexes were synthesized and characterized, where phen = 1,10-phenanthroline and PN are the natural products: caffeic acid (caf), cinnamic (cin) and cinnamic 4-dimethylamino acid (dmaca). The characterizations of ligands and complexes were carried out by electron injection mass spectrometry, UV-Vis, infrared, and 1H NMR spectroscopic techniques. The antioxidant activity of the compounds was investigated in relation to electron and hydrogen atom transfer using the free radical DPPH. In these experiments, only free caffeic acid and its [Mg(phen)2(caf)]+ complex showed antioxidant activity in relation to DPPH. An indirect test to determine the ability of superoxide dismutase (SOD) to inhibit the reactions induced by the superoxide radical anion was performed. Using the riboflavin reduction method in the presence of methionine and induced by 420 nm light irradiation, the antioxidant capacity of the complexes in relation to the superoxide radical was evaluated. In this study, antioxidant activity was observed for the phenolic compounds caffeic acid (caf) and cinnamic 4-dimethylamino acid (dmaca), as well as for their respective [Mg(phen)2(caf)]+ and [Mg(phen)2(dmaca)]+ complexes, with the highest inhibition percentages of O2.- were observed for the complexes. The antioxidant activity in relation to singlet oxygen (1O2) was performed using the paramagnetic resonance (EPR) technique. For the [Mg (phen)2(caf)]+ complex the IC50 value was 5.0 μg mL-1 and for the [Mg(phen)2(dmaca)]+ the IC50 value was 7.5 μg mL-1. The complexes did not inhibit the activity of the enzyme acetylcholinesterase. MTT assays to estimate the cytotoxicity of complexes in A375 human melanoma cells indicated IC50 around 6 μM for the 3 complexes studied.

This paper aims to analyze the role of the Brazilian State in territorial conflicts in the Xingu basin. To do so, we will make a geographic cut focusing on the Alto Xingu region, state of Mato Grosso, to present the problems present in this region that generate conflicts between the peoples of the Xingu Indigenous Park and the Soybean-producing Landowners. By using the epistemological basis of David Harvey's theory on the production of capitalist space in the 21st century, which, therefore, is a theoretical framework aimed at critical analysis on the process of capitalist territorialization in globalization, we will have a work related to political geography, reason why the territory will be the main category of geographic analysis applied to the study in question.

Knowing a child's preferences can be an essential strategy to motivate the child to perform tasks in the classroom context. For this, it is important that teachers know how to apply tests to identify these items of preference, especially in children with delayed language development. The present research aims to develop a teaching assessment and test its effectiveness by training teachers in conducting a Paired-Choice Preference Assessment based on Animated Auto-Instructional Video. Two studies were carried out, both developed with Special Education teachers and carried out within a public school, with three participants for each study. In the first, it was tested in a pre and post-test design, in three different conditions (Condition A, Condition B and Condition C), if the Independent Variables (IV), called: 1) Animated Auto-Instructional Video and 2) Instructional Guide (IG), were responsible for modifying the Dependent Variable (DV), called: Conducting a Paired-Choice Preference Assessment. The performance results of the three participants demonstrated the effectiveness of the training performed through Animated Videos. The difficulty of all of them was evidenced in the performance, especially in what concerns the measurement and control of time by means of the stopwatch. The purpose of the second research was to teach teachers through Animated Auto-Instructional Videos (IV), using a multiple baseline design between subjects to measure, in repeated sessions, whether the Dependent Variable (DV), called: Conducting a Paired-Choice Preference Assessment, remains stable throughout the sessions. Three Special Education teachers who work in the Multifunctional Resource Room participated in this study. The repertoire of each subject was evaluated in three baseline sessions, applied before the manipulation of the variables. After the intervention, the repertoires of these participants were again evaluated in three sessions held under the same conditions as the baseline sessions applied previously. The results showed that all participants performed better in the intervention sessions. The performance related to the control and measurement of time using the stopwatch was superior to the performance presented in the first study.

With the development of semantic technologies, the importance and the recognition of data as information sources grow. In this context, the data generated from researches are increasingly valued, since their publication allows the foundation of the results obtained with the scientific works, also helping in the production of new knowledge in a sustainable way. Thus, there is a need to organize these research data, so as to optimize their retrieval. For this purpose, vocabularies could be used. From the standardization of data representation, vocabularies allow data to be organized and retrieved efficiently. When considering the Web environment, the discovery of new data is also improved, using Linked Data principles, and the Data Catalog Vocabulary (DCAT) appears as a vocabulary aimed at describing catalogs and its datasets, seeking to favor their interoperability. The objective of the research is to analyze the characteristcs and fundamentals of the Data Catalog Vocabulary (DCAT) and the vocabularies adopted by it, for the publication of research data in the Linked Data principles, in order to identify the discussion on the subject in the literature and verify the use of it. Through exploratory, descriptive and theoretical research, it was possible to systematize and analyze the characteristics of the vocabularies, identifying that DCAT allows catalogs and datasets to be standardized, reducing ambiguity issues and providing the discovery of data and data services, since it has specific terms for this purpose. Thus, in line with Linked Data principles, the use of DCAT allows the benefits of sharing research data to be accomplished. An analysis of re3data platforms was also carried out in order to identify the current use of vocabulary by them, where we verified low adoption of DCAT. However, the results indicate the concern of these platforms with issues of findability, accessibility, interoperability and reuse, going against the Linked Data principles and the FAIR principles. The research revealed that there are few discussions about DCAT in the literature, especially in the scope of Information Science. Thus, we point to the need to better explore the possibilities of representing information in the context of research data. In addition, further discussions that align the knowledge of the area with the semantic tools and concepts applied to the Web enhance the benefits of finding, using and retrieving information, in addition to expanding and improving the knowledge and possibilities of information professionals' performance.

In this work, new properties, estimation methods, residual analysis and extensions are developed for regression models in the (0,1) interval considering the Johnson-SB type distributions (JSB). The extensions are zero-and-one inflated models and mixed regression models. New mixed-effects models for bounded longitudinal data in the interval $(0,1)$ based on the $JSB$ distributions are presented. The penalized likelihood estimators are obtained by maximizing the penalized likelihood and are computed by the Rigby and Stasinopoulos (RS) algorithm. From the Bayesian perspective, the No-U-Turn-Sampler (NUTS) is used to sample from the posterior distribution. Residual analysis is performed considering randomized quantile residuals. Simulation studies considering robustness to outliers from the distributions and extensions of the models to support 0 and 1 observations are presented. Three real data sets motivate the use of the new models. The first dataset contains the proportion of individuals vulnerable to poverty of the 645 municipalities from São Paulo state in Brazil and with no covariate. The second dataset incorporates the proportion of votes obtained by a political party in five Brazilian presidential elections, every four years, from 1994 to 2010, from the 75 municipalities from Sergipe state in Brazil. The third dataset comes from the public health area in Brazilian states. It contains the mortality rates from bronchial and lung cancer from the 27 Brazilian states over the last 30 years. The aim is to identify if factors like sex, age, and the Municipal Human Development Index of the state can influence the mortality rate. The $JSB$ mixed regression models and the Beta mixed model were applied. The $JSB$ mixed models display better values than the Beta mixed model for the model comparison criteria. The results and the residual analysis reveal that the $JSB$ models are an alternative to the Beta model.

Despite the well-known correlation between prolonged stress and the development of diseases, not every individual exposed to stressful situations develops stress-related disorders. This individual difference could be related to their ability to cope with the adverse events, that is, their resilience or susceptibility to the stress. In the context, this work aimed to evaluate the differences between the resilient and susceptible phenotypes in an animal model of psychosocial stress exposure. In the chapter 1, we evaluated the behavioral, molecular and cardiovascular differences in the resilient and susceptible phenotypes to the social defeat stress (SDS) in rats, and the effect of the N-Acetylcysteine (N-AC) treatment in such alterations. In the chapter 2, we evaluated the role of the ventral pallidum Npas1+ neurons in the susceptibility to the SDS in mice. Using the repeated SDS exposure followed by the social interaction test (SIT), we identified Wistar rats as resilient or susceptible to the SDS in the chapter 1. The susceptible rats showed social avoidance, depressive-like behavioral alterations, long-term memory impairment and cardiovascular alterations related to the development of cardiovascular diseases. Except for memory impairment, resilient rats did not develop the alterations found in the susceptible phenotype, in addition to show cardiovascular alterations related to a protective effect from the stress consequences in the cardiovascular system. These two phenotypes showed distinct alterations in the expression of DeltaFosB and the cystine-glutamate exchanger in the brain. The N-AC treatment reverted the depressive-like behavioral alterations in the susceptible rats to the SDS, but did not altered the DeltaFosB expression related to the stress-coping phenotypes. In the chapter 2, we verified that the activation of the ventral pallidum Npas1+ neurons increased the susceptibility to the SDS in mice, in addition to increase the anxiety-like behaviors. These neurons projects to diverse encephalic areas important in the stress-response, especially the nucleus accumbens, ventral tegmental area and lateral habenula. In conclusion, susceptible rats to the SDS showed numerous behavioral and cardiovascular alterations after repeated stress exposure, which are absent in the resilient rats. Such alterations seem to be related to DeltaFosB expression in brain areas related to stress-response. The N-AC treatment in able to revert the behavioral alterations, besides not being effective to change the neuronal molecular alterations related to stress exposure. The SDS susceptibility could be related to the activity of the ventral pallidum Npas1+ neurons, since their activation increased the SDS susceptibility in mice.

Fission Track Thermochronology (TTF) has been used for decades as a technique that makes it possible to date and infer the thermal history of rocks in regions of geological interest, from different minerals. The methodology is based on the study of fission tracks spontaneously generated by 238U or induced in a nuclear reactor by 235U, which after a chemical attack can be observed under an optical microscope. Specifically, this project focused on the study of the zircon mineral, which is a mineral that is very abundant in nature and that contains about dozens of ppm of uranium in its chemical composition. Therefore, it can be used as a thermochronometer in the TTF, where the density and length of the fission tracks in the mineral are useful for dating and inferring the thermal history of the rocks present on the Earth's surface. This is because the temperature to which this mineral has been exposed for millions of years causes the fission tracks to shorten. This phenomenon is known as annealing and can be better understood from kinetic models, known as annealing models. Such models use a data set that shows how the phenomenon interferes with fission tracks. The data set available for the calibration of TTF systems using NST zircon is extracted from a region that has a thermal history defined by a rapid cooling and the absence of a subsequent geological heating, being its dating from the Miocene geological era (~ 22 Ma). Therefore, the objective of this work is to obtain a new set of annealing data with zircons obtained from a region with a thermal history and geological era different from the NST zircon. For this, a sample of Poços de Caldas-MG was chosen, called ZPC whose dating back to the Mesozoic era (~ 80 Ma). Two aliquots were prepared: one containing only spontaneous fission traces (238U) and the other with only induced fission tracks (235U). Both aliquots were subjected to heating experiments for 1, 10 and 100 hours at a temperature between 500 and 800 ° C. The results showed the fission traces of the ZPC sample have behavior compatible with those of the sample commonly used by the scientific community. The new set of annealing data from the Brazilian sample was applied to annealing models and has potential as a data source for reconstructing thermal histories in regions of geological interest.
