    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.

    O bloqueio dos receptores NMDA ou CRF1 no núcleo intersticial da estria terminal impede a ansiogênese induzida pela ativação nitrérgica do córtex pré-frontal medial e derrota social em camundongos

    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.

    The use of educational games by teachers in their classes can have a significant and positive impact on their students’ learning and development skills. There are, however, some difficulties that can jeopardize the follow-up and assessment of the students while they are playing. This work presents a generic solution that can be applied to many kinds of educational games and offer a support for teachers to analyze, monitor and assess their students. Based on Information Visualization concepts, Learning Analytics and Game Learning Analytics, many steps were taken towards our goal. The first step comprised a survey of the main indicators that teachers find relevant. We invited 37 of them to answer an online questionnaire in order to understand their main difficulties and find out which analysis tools they needed. Doing so we were able to define a set of engagement indicators that were considered to be relevant by the teachers. The second step comprised the definition of which data should be collected from the games for each indicator. In the third step we developed a dashboard with a set of visual representations of each one of the indicators. To accomplish this, we used three educational games available at the REMAR Platform, each with different charecteristics. Finally, we then invited four teachers to assess our dashboard through an online questionnaire to check for clarity and understandability of the graphics we presented, as well as the dashboard usability. The teachers’ response gave us a strong sense that our goal was reached and that we developed a tool that is useful for the monitoring and evaluation of the students.

    This dissertation adresses the incorporation of Muslim immigrants and refugees in slaughterhouses to work in the Muslim religious slaughter known as halal. Through field research conducted with Muslim bleeders working at a Brasil Foods (BRF) plant located in the city of Chapecó-SC, I examine the process in which these people are incorporated in halal slaughter lines, as well as how, from their perspectives, this slaughter is practiced inside these slaughterhouses. Addressing the way slaughterhouses lure Muslim immigrants and refugees to work in the halal bleed, I point to a set of questions concerning the precarious conditions that characterize the lives of these workers in the slaughterhouses, as well as the ritual aspects that revolve around the slaughter. Because it is a religious slaughter practiced on a large scale by the meat industry, the research is therefore an interface in which I discuss migration, religion and work.

    The most abundant lycophytes from the fossil record of the Corumbataí Formation, Paraná Basin, are the Lycopodiopsis derbyi Renault, 1890, found in Guadalupian strata. Lycopodiopsis cf. derbyi present a wide occurrence in the rocks of the Passa Dois Group, which makes this taxón of great importance in the floristic scenery of the southwestern Gondwana, constituting part of the coastal vegetation of extensive flooded plains in the territory that today is the State of São Paulo and Southern Brazil. Brazil. The present study was carried out in the city of Rio Claro, State of São Paulo, in an outcrop, where an unprecedented and expressive phytopossiliferous assembly was preserved. The specimens found were attributed to Lycopodiopsis cf. Renault derbyi, preserved as compressão-impressions, and counter-molds and in a North-South direction. They were distributed over a large area, with massive concentration of specimens, including overlap, indicating the possible taphonomic conditions that led to the assembly. The fragmentation of the specimens occurred in the collection process, since in situ they were whole. There is a dichotomy in some stem fragments and throughout the assembly, there was different preservation among the specimens, with the preservation of three distinct levels of cauline decortication (characteristic of the group of Lepidodendrales). This register possibly comprises a non-selective parautochthonous monospecific assembly as it is a massive assembly. The morphological analyzes led to corroborate the decortication characteristic of the group, since in the same specimen there was the preservation of two cortical levels. Also, a branch over one meter long was recorded. It was the first record of a large group-to-group ratio, which although they were arboreal, were believed not to develop at high heights. This assembly presents the first record of mass mortality of Lycopodiopsis derbyi, described for the Corumbataí Formation. From the analysis and further interpretation of the data, it was possible to conclude that despite the massive concentration of individuals, the event that caused their deposition was not of great energy, as it preserved so many anatomical characters, and also allowed the preservation of a fish. articulated together with the branches. Also, dispersive energy spectroscopy (EDS) and stereomicroscope and scanning electron microscope (MEV) images indicated the occurrence of salts, which suggests a deposition paleoenvironment of brackish water-soaked areas.

    The lack of decent housing for people living in the countryside is one of the main factors of social vulnerability, with rural housing shortage reaching 783 thousand in Brazil. The construction industry is of great importance for the mitigation of this situation, with significant participation in the process of social, economic and environmental transformation. The industry now starts to reframe itself, incorporating concepts of sustainability in its construction processes. Since the early 2000s, several methodologies for the evaluation of sustainable performance of buildings have been proposed. However, the vast majority of these methodologies is focused on the assessment of the impacts of the urban environment of large centers on the surroundings. In order to evaluate the contribution to promote sustainability of buildings in rural environments by comparing the performance of traditional and alternative building systems, the present work proposes, using interest group surveys and the analysis of other evaluation methodologies and of application context, the creation of a decision aid method for choosing more sustainable building systems, which are aimed for rural housing of social interest. The proposed method is based on modeling built from Analytic Hierarchy Process (AHP), using the performance of the constructive system in four proposed aspects (“Ecological and Environmental”, “Social, Historical and Cultural”, “Economic and Financial” and “Technical and Performance”) as selection criteria. Due to the complexity and number of variables, a computational tool was built, using the Python programming language, to automate the processing of data. A case study was carried out to assess the model, in Assentamento Itamarati, located in the rural area of Ponta Porã-MS, Brazil. In this study, four wall solutions were compared (ceramic blocks, concrete blocks, compact soil-cement blocks and mechanically pressed compressed soil blocks). The soil-based systems had the best performance, of 29.00% and 26.30% for soil-cement blocks and compressed soil blocks, respectively, compared to the industrialized ceramic (22.63%) and concrete (22.07%) blocks. It is noticeable, from the results, that the proposed methodology presents itself as a viable solution for the implementation of constructive practices that contribute to the promotion of sustainability of buildings, customized to the reality of the countryside.

    Increasing biodiesel production is a worldwide need. Basic homogeneous catalysts are the most widely used by the biodiesel processing industry and present problems such as the need of best quality raw material, high waste generation and large number of biodiesel purification steps. Different heterogeneous catalysts were synthesized aiming to obtain a material with good activity and catalytic stability. Catalysts with acid sites containing DES (deep eutectic solvent) of choline chloride and p-toluenesolfonic acid (ChCl / PTSA) were impregnated in Areosil silica and SBA-15 mesoporous presented good catalytic activity in the transterification of methyl acetate with ethanol, but losing activity in reuse. Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium hydroxide (TPOAOH) was also prepared and used in the synthesis of basic heterogeneous catalysts by co-condensation and grafting methods, however TPOAOH did not increase the catalytic activity. The other group of heterogeneous acid catalysts was composed of ionic liquids derived from groups of imidazole and sulfonic, whereas the catalysts synthesized by co-condensation with this material did not present catalytic activity, unlike synthesized catalysts by grafting that were active, especially transesterification at 65 ° C, but remain unstable at reuse.

    Title: EVALUATION OF BACTERIAL ACTIVITY AND ANTINEOPLASTIC OF NEW Ag(I) COMPLEXES CONTAINING SEMICARBAZONES AND TRIPHENYLPHOSPHINES AS LIGANDS. The present work aimed to evaluate the influence of ligands triphenylphosphine and semicarbazone as a biological potential as silver(I) complexes with the following formula [Ag(L)(PPh3)2]+ and [Ag(L)2]+ (L= ligands: (E)-2-((E)-3-phenylallylidene)hydrazine-1-carboxamide – CSC and (2E)-2-[(3E)-4-Phenylbut-3-en-2-ylidene]-hydrazinecarboxamide – BSC). It was synthesized and characterized 4 new silver(I) complexes: two bis(chelate) [Ag(CSC)2]NO3 = CCA and [Ag(BSC)2]NO3 = BBA; two complexes containing triphenylphosphine and CSC ligands [Ag(CSC)(PPh3)2]NO3 = (CAP) and triphenylphosphine and BSC ligands [Ag(BSC)(PPh3)2]NO3 = (BAP). The characterization of the compounds was performed using NMR 1H 13C, IR, UV-vis, molar conductivity and elemental analysis (CNH). The CHN data exhibited adequate to the proposed structure. The complexes molar conductivity showed they are cationic 1:1 and stable on dimethyl sulfoxide. On the IR spectra, it was observed displacements regarding the free ligands, watching the characteristic stretching wave numbers of C=N and C=O, which indicated donating atoms as N and O. Accomplishing cellular viability assays (MTT) against tumoral cells of breast (MDA-MB-231 and MCF7) and non-tumoral and tumoral prostate cells (PNT2 and DU-145). It was verified greater inhibitory action of the complexes containing triphenylphosphine (BAP and CAP) in comparison to the bis(chelates), and the BBA complex showed larger values of IS (IC50[PNT2]/ IC50[DU-145]) for the prostate evaluated cells (IS = 3,13). DNA interaction assays showed weak or non-interacting nature with the synthesized complexes and DNA, which suggests that the therapeutic target is another. The evaluation on bacteria inhibition evidenced that CAP complex is a promising antimicrobial agent, with a inhibitory rate higher than 70% such as Gram-positive as Gram-negative bacteria.

    Multiple Sclerosis (MS) is an inflammatory demyelinating (that is, with myelin loss) disease of the Central Nervous System (CNS). It is considered an autoimmune disease in which the immune system wrongly recognizes the myelin sheath of the CNS as an external element and attacks it, resulting in inflammation and scarring (sclerosis) of multiple areas of CNS’s white matter. Multi-contrast magnetic resonance imaging (MRI) has been successfully used in diagnosing and monitoring MS due to its excellent properties such as high resolution and good differentiation between soft tissues. In this context, from a computational standpoint, two important goals stand out: lesion segmentation and lesion classification, the latter being related to the identification of which lesions are under an inflammatory state, also called active or enhancing lesions. Nowadays, the preferred method to segment MS lesions is manual delineation, made by specialists with limited aid of a computer. However, this approach is tiresome, expensive and prone to error due to inter- and intra-variability between observers caused by low contrast on lesion edges. Here, we propose the development of an automatic computational technique based on Student’s t-distribution finite mixture models and probabilistic atlases to segment and measure MS lesions volumes in MR images. Regarding the identification of enhacing lesions, Gadolinium-based contrasts are used to visually highlight them during an MRI procedure. However, recent studies indicate that patients gradually lose their ability to eliminate the contrast substances from their bodies when they undergo many contrast injections throughout their lives, which is the case for MS subjects. In this sense, in this work we used textural features to distinguish enhancing (active) and nonenhancing lesions without the aid of intravenous injection of Gadolinium-based contrast, thus eliminating the risk of accumulation of this substance in one’s body and making the MRI procedure faster and cheaper.
