    The environmental problem affects the lives of billions of people and, given the magnitude with which it has presented itself, arouses worldwide concern. In this context, Environmental Education (EE) plays an important role in the formation of committed subjects in the search for solving social and environmental problems or alternatives to the current development model. Considering that multiple political and ideological influences have shaped EE, we cannot refer to it in the singular, since there are several possible ways to conceive and practice it (CARVALHO, 2004; LAYRARGUES; LIMA, 2014). Thus, this study aimed to analyze the different modalities of EE existing in elementary schools of the municipal network of Araraquara, São Paulo, in order to discuss its specificities, potentialities and challenges. In this network, EE processes take place in an interdisciplinary manner, in Common Base disciplines, and through special discipline, from the diverse part of the curriculum. Data were collected through field research in three school units: one full-time elementary school, one part-time elementary school, and one full-time education center that serves students in the regular school counter-shift. We conducted semi-structured interviews with teachers and pedagogical coordinators, document analysis of the schools involved and the Municipal Secretariat of Education, in addition to the municipal legislation establishing the Municipal Environmental Education Program. The results were analyzed through elements of content analysis and organized in four axes: “Working with EE in school units”, “Perspectives and trends of EE in the EUs”, “EE as a discipline” and “Teacher Training “We find that there are EE processes going on in this network, although under different organizations and which are mostly between the conservationist and pragmatic macrotendencies (LAYRARGUES; LIMA, 2014), and that although there is ongoing work in EE workshops of two school units investigated, the continuity of the work alone does not guarantee a critical perspective in its development. We consider the formation of teachers to work in this perspective as fundamental, as well as the improvement of the “Municipal Environmental Education Program”. Faced with existing challenges, both in interdisciplinary work and workshops, we understand that there is potential for conducting a critical EE work, taking the debate on environmental issues beyond the discussion on whether or not a discipline.

    This thesis proposes to present a mapping of the parliamentary profile of the deputies who assumed mandates in the 2003-2007, 2007-2011 and 2011-2015 legislatures, through the analysis of the legislative production of these women, highlighting the proposition of draft laws, in order to verify the extent to which female parliamentary action results in substantive representation in the Brazilian Federal Legislative Chamber. This research is based on a theoretical debate on the main conceptions of political representation, with emphasis on substantive representation and its consequences in the political space. Thus, the substantive representation is considered from the representative's activity, that is, from the content of the political action of that leader and what is its correspondence with the interests of the electorate. The data of this work were collected in the Chamber of Deputies Portal, identifying the naturalness and party bond of the deputies, number of bills proposed by each parliamentarian, type of authorship of the proposition, status of the matter in the legislative process and in the case of propositions archived, the reason for this archiving was collected. It was also verified the content of each proposed project and based on the committees that debated the matter, a classification of 27 themes addressed by the deputies in their projects was defined. This thesis shows that parliamentarians propose a number of projects commensurate with their male counterparts, more than 50% of the propositions are the sole author and, as far as the proposition themes are concerned, the areas related to “care” and to the same extent “hard” such as labor, economics, finance and taxation, administration and public service. Regarding the themes on feminist and women's agendas, they add up to a percentage of only 12% of propositions presented, and it appears that these matters address issues related to work, women's health and violence against women. In short, female underrepresentation in politics is a barrier to be broken, about women elected identify important advances in their parliamentary performance, they are debating issues considered masculine and present an autonomous performance in Parliament, so this research points to importance of the presence of minority groups in elected positions. In the case of deputies, the increased female presence in this political space strengthens women's substantive representation, and can contribute to gender issues on the agendas of parliamentarians of both sexes.

    This thesis was written in the form of a compendium of scientific texts. It included four studies that supported the planning and implementation of investigations that aimed to identify critical parameters in the establishment of the repertoires of looking direction and Perspective Taking for children with and without autism. First, the first experiment investigated whether changes in a procedure already replicated for multiple exemplar training would enable the verification of generalized operant characteristics for two children within Autistic Spectrum Disorder (ASD) (Study 1). Second, observing a lack of studies in joint attention literature using a single-subject design, the aim was to investigate changes individually in eye-tracking patterns (via an eye-tracking device). Additionally, the vast majority of the studies in the area focused on the characterization of eye tracking in assessment in isolated tasks, with little explored as the eye-tracking patterns varied throughout the learning of responses, which guided the research question of Study 2. The first two studies explored joint attention responses (i.e., following the direction of someone's gaze), and they aimed to investigate and improve the social interaction behavior in very young children and provided relevant information for planning intervention for children with autism. However, social interaction, in general, can include many more complex responses that were not addressed in both previous investigations (Studies 1 and 2). Thus, for a broad interpretation of this phenomenon, in the sequence, a theoretical investigation was proposed. This investigation aimed to develop a functional analysis based on the Multi-Dimensional Multi-Level (MDML) framework for relational repertoires. This analysis allowed to establish responses for the development of Perspective-Taking (Study 3). Finally, the hypothesis raised about the minimum relational repertoires necessary for establishing Perspective-Taking in the previous theoretical research inspired an empirical investigation (Study 4). This last study involved the development of tasks to assess relational repertoires in a child with and another without autism with a similar development profile. Besides, this study also aimed to teach and develop the necessary relational repertoire that potentially would enable the presentation of Perspective-Taking, which were deficient for the child with autism. Subsequently, this teaching procedure effects for the behavioral repertoire of the participant were evaluated. In summary, the present thesis explored both fundamental and complex repertoire, crucial for the proper establishment of social interactions: gaze-following responses (Studies 1 and 2), and relational responses for Perspective-Taking (Studies 3 and 4). Both repertoires investigated seem to be fundamental for overcoming significant social barriers in individuals with autism.

    The objective of this work was to analyze the hydrodynamic behavior of soil e potential groundwater recharge trough stormwater infiltration wells, built in real and pilot scale at the Federal University of São Carlos using monitoring and modeling. Therefore, it will be performed physical and hydraulic analyzes of the soil, monitoring of volumetric soil moisture, hydrological data and water level inside the wells, and rainfall simulations with 2000 L and 10000 L reservoirs. The modeling were developed by the Soil Water Balance Method and numerically using Hydrus 1D version 4.16 and 2D/3D version 2.5 softwares. The soil of the study area was heterogeneous in relation to pore size and distribution, which caused the saturated hydraulic conductivity of the soil (Ksat) to vary from 1.58 10-4 to 9.52 x 10-3 cm / s, values that assure the adequacy of the area for the implantation of stormwater infiltration wells. Among the methods used to determine Ksat employed in well desing, those proposed by Cauduro and Dorfman (s / d) and Pratt and Powel (1992) were more adequate. Soil moisture monitoring showed that the wetting front reach does not depend on the well diameter, but yes of the water level height inside well and that the surfaces that effectively contribute to infiltration is below half of this height. The localized and large distribution of runoff promoted by the well made the wetting and drying cycle effect were striking in the first operations of the structure. The increase in the well diameter decreased the soil water infiltration rate, it is consequence of its increased reservoir capacity and decreased resistant energy of water flow in the soil. In the estimation of groundwater potential recharge by the Water Balance Method, when considering rainwater management using infiltration wells, the average recharge value found for 2017 and 2018 was 2,72 times higher than for the grassland scenario, therefore, the wells contribute effectively to groundwater recharge. Two-dimensional numerical modeling of groundwater dynamics was inconclusive by Hydrus 2D/3D and Hydrus 1D simulation showed that the average potential recharges for 2017 and 2018 were 86, 84, 82 and 80% of total precipitated in the period, when the water table level was 1, 2, 5 and 8 m from the bottom of PGHidro, respectively, and the inicial recharge time is directly influenced by table level and rainfall distribution. In conclusion, the results showed the importance of considering infiltration wells in urban management, not only for direct runoff control but also as a source of groundwater recharge.

    Hepatitis C is an infectious disease caused by the Hepatitis C Virus (HCV) and usually asymptomatic in the acute phase. Globally, an estimated 71 million people are infected with HCV and approximately 400,000 deaths happen annually due to complications from the disease, such as cirrhosis and liver cancer. This study aimed to develop and validate a rapid immunochromatographic test for the detection of anti-HCV antibodies, the Imuno-Rápido HCV, by comparing the performance of this product with a second commercially available test (Commercial A) with the same methodology and ELISA methodology (Murex anti-HCV 4.0, DiaSorin) considered gold standard. Tests for validation include repeatability and reproducibility analysis, real-time and accelerated stability analysis, clinical sensitivity and specificity measurements, and positive and negative predictive values. In this study, 383 samples characterized by ELISA methodology were included and, by comparing the results, the clinical sensitivity and specificity parameters, positive and negative predictive values for the immunochromatographic tests Imuno-Rápido HCV and Commercial A were measured. For both immunochromatographic tests, a value of 100% were found for clinical sensitivity and negative predictive value. Clinical specificity values were 99.7% for Imuno-Rápido HCV and 100% for Commercial A test and positive predictive values for these kits were 98.6% and 100%, respectively. Repeatability and reproducibility analyzes showed concordant results in 100% of the tests, and real-time and accelerated stability assessments demonstrated the ability of the kit to maintain its proper functioning over time even under temperature stress, suggesting its ability to maintain stable for at least 18 months. These results corroborate the hypothesis that the Imuno-Rápido HCV has performance similar to commercially available kits that use the same methodology and is able to assist in the diagnosis of HCV infection safely and quickly, combined with easy execution and low cost.

    This is a documentary research, of a qualitative character, and aims to analyze and portray the personal meanings that the graduates of PIBID / UFSCar / Special Education attribute to the teaching activity, from their experiences as scholarships for Initiation to Teaching of that program. The research is based on theoretical contributions that concern the concepts: 1) Personal sense, according to the Historical-Cultural theory; 2) National Policy on Special Education from the Perspective of Inclusive Education; 3) The professional profile of the Special Education teacher; 4) Collaborative Partnership between University and School in the context of PIBID. It was conducted by the following question: What personal meanings did the alumni grant to the teaching activity, when writing their portfolios, while participating in the PIBID / UFSCar / Special Education subproject? The personal meanings were explained in portfolios' writings, especially with regard to the Thematic Axis: Discussions, reflections and development of learning situations and other curricular themes, from PIBID-UFSCar. The choice of the Thematic Axis is justified by the fact that it provides the investigation of learning situations within the classroom, where the contact of the scholarship holder and the target public of Special Education occurs. The portfolio is the instrument from which the data was collected and was a form of registration adopted by PIBID, with the purpose of systematizing the actions developed during the participation of the ID grantee in the program (BRASIL, 2013). We therefore selected three portfolios, which were organized, in principle, into five categories: 1) View of the fellow on inclusion; 2) PAEE student; 3) Curricular adaptations; 4) Strategies reached between regular classroom teacher and fellow and 5) Contribution to the initial training of the fellow. Subsequently, we summarized these categories in 3 categories due to the correspondence between them. The categories were arranged in: 1) Personal sense / View of the grantee about PIBID / Special Education; 2) Personal Meaning / Learning Situations lived in the classroom and 3) Personal Meaning / Contribution to Initial Training. When analyzing the available portfolios, we were able to list 5 categories for the Personal Senses of the 3 Graduated Fellows, namely: the fellowship's view on inclusion; PAEE student; curricular adaptations; strategies achieved between regular classroom teacher and fellow and contribution to the initial training of the fellow. Subsequently, we summarized these categories in 3 categories due to the correspondence between them. The categories, then, were arranged in: Personal sense / View of the grantee about PIBID / Special Education; Personal Sense / Learning Situations lived in the classroom and Personal Sense / Contribution to Initial Training. With the results obtained, we saw that the Scholars' Personal Sense are focused on the concept of co-teaching, shared and interdisciplinary work, curricular adaptation, practical training and concern for the PAEE student's emotional state in the context of the classroom, which contrasted with the strong presence of traditional teaching, concern with routine, order, repetition and memorization on the part of the conducting teachers, who, many times, delegated responsibility for the production and adequacy of the material adapted for the BEs, therefore , in all the analysis, it is evident the difficulties to carry out the collaborative work, and the importance of the horizontal dialogue between scholarship and conducting teacher. In the final remarks, we explained, in order to answer our research question, that the Alumni Fellows manifested their personal senses based on their written records in portfolios, concerning the teaching activity, when they were inserted in PIBID. Since, when going through the 03 categories listed, BE-1,2,3 highlighted the convergence of their actions in the face of concepts about the co-teacher, collaborative partnership, concern with the emotional state of the student in the context of the classroom providing support by curricular adaptation in the monitoring of the PAEE student within the classroom.

    The approach of written language in early childhood education has been over the decades causing differences of opinion among scholars in the area, as well as among teachers who work in this stage of education. Although the legal guidelines point the way for teachers to follow, they are open to interpretation in the context of practice. This led us to inquire about the interpretations that are present in the daily life of classrooms regarding the learning of written language. The purpose of this qualitative research, guided by the Policy Cycle Approach, was to investigate the teachers interpretations - focusing in classes with children from 5 to 6 years old - of the current official texts regarding the written language, in Rio Claro public schools. One of the methodological procedures used for the production of research data was the semi-structured interviews conducted in focus groups with the teachers of the classes in question. For this stage of the work, one school from each of the 12 regions was selected, according to the subdivisions made by the Municipal Secretariat of Education, totaling the participation of 38 teachers. In order to understand the context of influence and the context of text production, which resulted in the elaboration of the municipal document, we conducted a semi-structured interview with the Commission Coordinator responsible for the elaboration of the Curriculum Guidance for Rio Claro Early Childhood Education and with the Coordinator of Early Childhood Education of the municipality. These interviews, associated with the teachers' focus group interviews, allowed us to understand that the origin of the document was marked by studies and disputes of ideals. Also although the participation of the entire public school network - through the coordinating teachers - was desired, it did not go as expected, as many coordinating teachers did not share information about the document with their group of teachers. Besides that, we analysed the document of the schools to which the teachers participating in the research were linked (Pedagogical Political Project), as well as their respective documents (Annual Planning and Logbook).The information found in the documents was validated through focus group interviews and analysis of children's material (notebook activities, separate sheets and portfolios) in the context of school practice. According to the analysis of the research data, it was possible to verify four different interpretations of the same official text (Curriculum Guidance of Early Childhood Education of Rio Claro) about the work to be developed with the young children. According to which, the written language in the Early Childhood Education must: prepare for entry into Elementary School through mechanical practices and exercises that enable the memorization of letters and words; emphasize the social aspect of the child in the acquisition of the alphabetic writing system; prioritize the understanding of the social function of writing; and finally, to promote the initiative and exploration of the language written by the children. These different interpretations of the same official text, found in the context of school practice, lead us to reflect on the influence of teachers' experiences and conceptions on their pedagogical practices. Thus, the data produced in this research can serve for discussions in the area, as well as enable the municipality to understand the different interpretations of working with written language in early childhood education. From this understanding, the municipality can also propose collective actions aimed at improving the quality of public education offered to the young children.

    This study analyzes and characterizes the monographs presented by native Brazilian people graduated between 2014 and 2017 who ingress on undergraduate courses through the Affirmative Actions Program of the National University of São Carlos. The objective was to verify which knowledge were brought by native Brazilian students of different ethnicities at their monographs and their collaboration to a greater respect of diversity and democracy in Brazil. Eight monographs were selected and read and according to the issues addressed it was analyzed the thematic focus, the theoretical and methodological references, the procedures adopted for data collection, the systematization of the results and the whole undergraduate process of each student. This analysis considers that in a democratic society the inclusion of minority citizens - e.g. the native Brazilian people – cannot rely only on their access to formal education and with their presence at the university, the education process should be modified valuing their culture, their knowledge and their lifestyle – opposing the commonly ethnocentric practice that has always sought to “civilize” them. It was possible to observe that regardless the undergraduate course most works presented themes valued by their ethnic groups – such as legends, myths, rites and games. In addition, it was observed that they used the traditional approaches of their culture to account of the history of their people and the struggles to delimitate and description of their lands and alternative ways to geographical localization.

    This thesis, presented to the Graduate Program in Education at the Federal University of São Carlos, has as object of study the Curricular Guidelines for the major in Pedagogy, approved in 2006, the Resolution 1, CNE/CP and the Resolution 2, CNE/CP/2015, which also deal with pedagogue education. The aim of this thesis is to understand the history of creation and the development of Pedagogy majors in Brazil, as well as the theoretical-practical clashes concerning the curricular guidelines among educators and education specialists, especially in ANPEd, ANFOPE, ANPAE, ANDES and FORUMDIR. About the typology, this is a historical research, because it's object of study is inserted into a historical treatment of the conceptions and practices of the pedagogue education in Brazil's history of education. It is a bibliographical and documental research, since it seems to analyze what is already produced in different publications and documents (Constitution, Laws, Decrees, Legal Opinions, Resolutions etc). However, it is also an empirical research to the extent that it comes from the observation provided by all my experience in the area. Grounding itself on the results, in the light of the Marxist concept of "social praxis" and omnilateral education, and the concepts by Gramsci, especially the relations between the universal and the particular, his historicist conception of reality, of work as pedagogic principle, and my own experience as a teacher training student in High School, Pedagogy undergraduate student and education professional, the present research points out the limits of the Curricular Guidelines while shows an alternative to make this relation become fruitfully dialectic, forming educators not only instructed and technically competent, but also cult, able to form citizen students who are not passive but apt to take important roles in the society, towards it's transformation. Keywords: History of Pedagogy in Brazil. Pedagogy Curricular Guidelines. Theory and Practice

    In the last decades, early childhood education has been expanding, besides being solid in the context of formal education, it has also been presented as a target of government programs and actions, guiding documents and guidance materials aimed at ensuring the rights of young children. Although in recent years we have observed a remarkable increase in the number not always accompanied by high quality standards, early childhood education in Brazil has faced many controversial issues, including the evaluation that appears as the theme of this research project. The evaluation is a theme that presents a considerable range of of places in kindergarten, considering the data from the School Census presented by the National Institute of Studies and Research Anísio Teixeira (INEP), pointing to an 11.1% growth in the number of enrolments In early childhood education from 2014 to 2018, this expansion cannot yet be considered sufficient to meet the demand of different Brazilian states. We should also consider that this expansion is strongly evident in preschool over kindergarten, indicating that the discrepancy between the stages has not yet been overcome despite the development of broader public policies. Thus, marked by a context of quantitative expansion, but conceptions that unfold in different evaluative practices and the present work intends to investigate the conception of evaluation of the managers and teachers of the kindergarten of the municipal network of the city of São Carlos-SP. From a qualitative point of view, it is based on the methodology of the policy cycle approach, as we see the importance of considering the policy from its production (at the macro level) to its interpretation and application (in micro contexts, such as the Municipalities). To this end, the research sought to be based on bibliographic, documentary and field research that took place through semi-structured interviews with the educational supervisor and the presidents of the Municipal Education Council of the bienniums 2016-2018 and 2018-2020, and the realization focus group methodology with the kindergarten teachers of the municipal network. We conclude from the data obtained through this research that the continuing education of teachers working in municipal early childhood education is necessary and urgent. In addition, the municipal network of São Carlos (counselors, directors, teachers and community) presents the need for the appropriation of knowledge in the area of early childhood education, and especially in the evaluation theme, which enable the creation, implementation and management (jointly) concatenated actions that are part of an educational public policy whose main objective is the integral development of the child and to secure such right.

    DEVELOPMENT OF AN ANALYTICAL PROCEDURE FOR PHOTOMETRIC DETERMINATION OF MERCURY IN SEDIMENT AND DRINKING WATER EMPLOYING THE FLOW-BATCH AND FLOW MULTICOMMUTATION PROCESSES: This work deals with a multicommuted flow-batch setup and a photometric procedure for the determination of mercury in waters and sediments. The setup was designed to exploit facilities achieved by associating flow-batch and multicommuted flow analysis approaches, thus allowing the implementation of a versatile solvent extraction and pre-concentration strategy. The method was based on the reaction of Hg(II) with dithizone in chloroform medium, which was used as a extracting organic solvent. The flow analysis system constituted by a homemade syringe pump module, a set of solenoid valves, two mini-pumps and a flow-batch chamber. The homemade photometer comprised a light emitting diode (LED), a photodiode and a homemade flow cell (50 mm long). The flow system and the photometer were controlled through an Arduino Due board, running a software wrote for this purpose. After selecting the better operational conditions, the effectiveness of the proposal was evaluated by determining mercury in waters. Aiming to accuracy assessment, sample were also analyzed employing an independent method. Accuracy was accessed using the spiking methodology and recovery ranging from 92 to 108 % was observed. Other profitable features such as a linear response ranging from 0.5 to 10.0 µg L-1 (r = 0.9984); a limit of detection 0.38 µg L-1 Hg(II) (n = 10); consumption of dithizone and chloroform 0.18 mg L-1, and 800 µL per determination, respectively; coefficient of variation (n = 10) 2%; and a sampling rate of 20 determination h-1 were also achieved.

    This work has as presupposition that the teaching of physics can train students to prepare them for work and citizenship, since it allows to relate the contents and physical phenomena with the reality of the students, making them critical and responsible so that they can make decisions scientifically and technologically. Thus, characterizing the contextualization of teaching as a possibility to lead the student to a citizenship education through teaching physics concepts linked to their experience and being thought as a pedagogical resource or as a guiding principle of the teaching and learning process we elaborated an experimental contextualized research activity and a stimulated interview in order to analyze the relationship that students establish with the contextualization of contents from an investigative activity and how they perceive the aspects of contextualization within the discipline. The activity was applied to students of the 1st year of high school of a public school in the city of São Carlos. The research has a qualitative methodological character and, for data analysis, significant parts of Content Analysis were used, in which categories were created that best represented the students' relationship with the contextualization during the activity. We realize that curricular content has a difficulty in bringing school knowledge closer to students 'curiosities and that there is a challenge in physics classes to identify students' needs and curiosities in order to articulate them with curriculum content.

    This research analyzed the recently approved Labour Reform (Law No. 13,467 of November 2017), presented by the president Michel Temer in his government. It aims to associate this Reform with the neoliberal policy prescription - which was the issue of a limited debate - which has already been presented before and during the Government of Fernando Henrique Cardoso (FHC), during his first term in 1998. The association of this Reform with the neoliberal ideals sought to establish a more accurate analysis of the arguments that supported the defense of the neoliberal policy prescription adopted by the FHC government. It was also analyzed the theories that originate from or are correlated with the Chicago School which served as an experiment for the application of economic adjustments in several countries, notably in those from the southern cone of the American continent. Among these several points of views we seek the elaborations belonging to the supporters and formulators of these theses that discussed the need for economic adjustments in the peripheral countries and also tested, through practical experiences of today, the effectiveness of theories that, for example, defended the investment theory in human beings as a policy of qualification and economic return. We are talking about human capital theory. The analysis of these positions contributed strongly to the understanding of the numerous movements that drove the approval of the Reform, the interest groups behind it and, fundamentally, the impacts on the reality of salaried employees in the country, resulting from the newly approved labour legislation. To gather this data, a literature review and documental research were conducted.

    There are several methodologies that facilitate the teaching of physics. In this work, we studied the use of the Game and the History of Science as tools for teachers. The product presented here and its application were developed from Vigotski's theory of learning. The final material consists in a card game called The Physical World. The game, which can be played by up to five gamers, was originally created for use by students in the third year of high school. In this game, the student goes through all phases of physics, enabling a learning of new concepts and a review of old concepts. The educational product was applied to seven different high school classes of a public school in Carapicuíba - SP. We obtained good results in the application classes, with increasing interest in Physics and History of Science. The results are also demonstrated through evaluations that suggest a evolution in the learning performance during the process. Thus, this product is an instrument that can be used by the teacher in the classroom, seeking to promote and stimulate students' learning in a more pleasurable way.

    The diversity of cancer diseases and the side effects caused by the drugs commonly used in cancer treatment require different antineoplasic agents able to operate more specific and in a way to minimize the side effects. With that in mind, efforts are made to develop compounds for selective biological target, such as the enzime topoisomeraseIIα, or TOPOIIα, which has been widely studied. In a recent work of our research group, it was found that Pd(II) complexes with thiosemicarbazone ligand (N, S donor) and co-ligands’ phosphinic and halides, in a distorted square planar molecular geometry, showed cytotoxic activity against breast and lung tumor cell lines; they also inhibited TOPOIIα enzime at a 2,8 times smaller concentration than the standard drug, etoposide. This activity was atributed to the interaction of the complexed thiosemicarbazone ligand with enzime’s active sites. Therefore, in the present work, it was attempt to comprehend the importance of the co-ligands and of the thiosemicarbazone identity, as well as the metallic ion influence in the biological activities. Thereunto, in this work, changes in the molecular framework were performed: (i) substitution of co-ligands for another thiosemicarbazone molecule; (ii) changes in the thiosemicarbazone structure; (iii) metal ion identity. It was synthesized six thiosemicarbazones ligands (L) (N, S donor), thirteen new bischelate complexes structures in a square planar geometry : twelve Pd(II), divided in two analogues series of general formulae [Pd(L)2] and [Pd(HL)2]Cl2, differenciated by anionic and neutral ligands coordination, respectively, and a Ni(II) complex, [Ni(L)2]. After obtaining all the compounds (caracterized by spectroscopic and spectrometric thecniques), the investigation of cytotoxic activity of ligands and their Pd(II) complexes against the tumoral cell lines MCF-7 (breast) and DU-145 (prostate) and non-tumoral PNT2 (prostate) showed that the free thiosemicarbazone ligands presented low cytotoxicity (IC50> 50 μmol.L-1), while their Pd(II) complexes containing the lower molecular masses thiosemicarbazone presented IC50 values in the 12,00-0,22 μmol.L-1 interval for tumoral cell lines. It was not observed selectivity among the cell lines tested (tumoral and non-tumoral). Comparing the cytotoxicity exhibited by a Pd(II) complex containing the co-ligands, [PdCl(BT-M)(P(4FPh)3] (IC50 = 0,56 ± 0,1 μmol.L-1), and its bischelate anologues complexes of Pd(II) and Ni(II), [Pd(BT-M)2] (IC50 = 0,43 ± 0,3 μmol.L-1) and [Ni(BT-M)2] (IC50> 12μmol.L-1), against tumoral breast cancer cell line MDA-MD-231, it is suggested that metal ion identity is essencial in the cytotoxicity of complexes. Molecular Docking studies showed that the Pd(II) bischelate complexes do not present affinity with TOPOIIα active sites. Experimentally, it was observed that the most cytotoxic complexes of Pd(II) and the Ni(II) complex do not Interact significantly with DNA and they are not able to inhibit TOPOIIα (at concentrations of 1, 10 e 50 μmol.L-1), pointing out that these are not the biological targets of the complexes. It is suggested that, the absence of co-ligands could be the responsible for the loss of enzimatic inhibitory activity.

    Nitric oxide (NO) release in the right medial prefrontal cortex (RmPFC) produces anxiogenesis. In the bed nucleus of the stria terminalis (BNST), a region that receives neuronal projections from the mPFC, NO also provokes anxiety, an effect that is blocked by local injections of corticotrophin-releasing factor type 1 receptor (CRF1) or n-methyld-aspartate receptor (NMDAr) antagonist. Anxiety is also enhanced by social defeat stress, and chronic stress impairs and facilitates, respectively, PFC and BNST roles in modulating behavioral responses to aversive situations. This study investigated whether the (i) chronic social defeat stress (CSDS) increases NO signaling in the mPFC; (ii) anxiogenic effects provoked by intra-RmPFC injection of NOC-9 (an NO donor) or by CSDS are prevented by intra-BNST injections of AP-7 (0.05 nmol) or CP 376395 (3.0 nmol), respectively, NMDAr and CRF1 antagonists, in male Swiss-Webster mice exposed to the elevated plus-maze (EPM). Results showed that (a) CSDS increased anxiety (i.e. reduced open-arm exploration) and repeatedly activated NOSn containing neurons, measured by ΔFosB (a stable nonspecific marker of neural activity) + NOSn double-labeling, in the right (but not left) mPFC, (b) NOC-9 in the RmPFC also increased anxiety and (c) both CSDS and NOC-9 effects were reversed by injections of AP-7 or CP 376395 into the BNST. These results suggest that NMDA and CRF1 receptors located in BNST play an important role in the modulation of anxiety provoked by NO in the RmPFC as well as by chronic social defeat in mice.

    This investigation considers the idea of educational processes as part of social environments. Through this point of view, we have the understanding of museums as places where knowledge and the sense of era are approached, transposing to the pedagogical area a rich multidisciplinary environment, resulting in its use as a tool for the enlargement of students cultural background. The objective for this research is to analyze educational potentialities which were observed during the visits to the museums, based on the understanding of middle school students. For this qualitative research, we considered the methodology of a case study, in order to understand and emphasize its singularities, which is, in this case, the pedagogical visits provided by SME, in São Carlos. The data were gathered through forms which were distributed to 124 6th grade students. The results show a variety of meaningful knowledge, either part of the curriculum or extracurricular, which enlarges their cultural capital and spread the museologic culture.

    The present work aims to discuss and problematize the concept of impartiality of the interpreter of libras (Brazilian sign Language), from the analysis of the facial microexpressions produced by him, describing the facial expressions displayed by This professional in a situation of interpreting an emotionally charged discourse. Given that the microexpressions are subtle emotions that appear on the face as we try to oppress a specific emotion, the work aims to analyze a video at the time of the interpreter's performance, in a situation in which he has no prior knowledge of the material he will Interpret. Based on these data, we tried to describe the facial microexpressions, in order to evidence possible emotions contained by the interpreter. From the analyses, it was possible to verify by the results of actions taken as impartial, there is an intense work of the professional interpreter to contain formulations that transparethe aspects of his subjectivity. The analysis of microexpressions, however, reveals that in the smallest details of facial gestures, it is possible to identify indices of emotions caused by the stress situation in question. This discussion draws attention to the need to conceive the professional interpreter of pounds as a human being (and not as mere conduit of information from a source A to a destination B), who, acting in situations which put in a situation of discomfort, sometimes , it will manifest, although minimal expressions, complex conceptions and perceptions of its subjectivity.

    ELECTROCHEMISTRY AND STM-ASSISTED MOLECULAR ELECTRONICS STUDY OF BIMETALLIC HEXAPHYRINS. The electron transport in porphyrinoids are related to several bioprocesses in Nature, from conversion from solar energy to chemical energy in photosynthesis to the transport and reduction of oxygen in aerobic animals. Due to these characteristics, several bioinspired applications have used this class of materials, photovoltaics, water splitting, catalysis and photodynamic therapy. To further understand how this process occurs in expanded porphyrins, 5 hexaphyrins in Hückel aromaticity were synthesized, with and without metal centres. These molecules were characterized by spectroscopy, electrochemistry and through molecular break junctions. The absorption spectrum of hexaphyrins show several possibly transitions, which splits and broadens with the addition of metal centres due to the degeneration of the molecule’s orbitals. The spectroscopic band gap was characterized by fluorimetry showing a gap between 1.12 to 1.20 eV for the molecules synthesized. Electrochemistry measurements shows several distinct quasi-reversible redox pairs. The addition of metal centres shifted the processes accordingly to the electronegativity of the metal centres. Due to the severe number of reactions a diagnosis criterium was developed to indicate which peaks corresponds to reactions in the macrocycle or its ligands and which are likely to occur on the metal centres. The molecular conductance of the hexaphyrins were studied with STM assisted break junctions on non-modified and modified gold as electrodes. The gold modification was proved necessary due to the lack of interactions between the molecules and the metal electrodes. Several current signatures were observed on 4-TPy modified gold. This corresponds to all possible molecular junction conformations. Upon the addition of metal centres, a similar trend is observed for each metal, indicating that the molecule properties do not impact as much as the conformation of the molecular wire.
