In this work, the corrosion behavior of NiTiNb shape memory alloys (SMA) in aqueous medium containing chloride ions was characterized. The study was performed in alloys of six different compositions, which were melted in an arc-furnace, under controlled atmosphere, with 3, 6 and 9 at.% of Nb addition, while the ration Ni/Ti was maintained constant at 1.00 and 1.07. The objective was to evaluate the Nb content effect on the composition and corrosion resistance of the passive film, supported by its microstructural and thermal characterization. The electrochemical behavior in sodium chloride solution (NaCl) 3.5 w.% was evaluated using potentiodynamic polarization and potentiostatic polarization techniques, to verify the pitting corrosion resistance of alloys, comparing with an equiatomic NiTi alloy. The analyses of the passive film composition was made by X-ray photoelectron spectroscopy (XPS). The alloys exhibit passivity in 3.5% NaCl solution, however, both the passivity zone expansion and the pitting potential (Epite) of the alloys increase their respective magnitudes with the increase of Nb content. On the other hand, the corrosion current density of the alloys are similar, showing that the alloys have the same general corrosion rate, that remains approximately unchanged with composition and microstructure variations. Alloys with Nb contents below 9 at.% exhibit susceptibility to pitting corrosion and cracking corrosion, but they show better resistance compared to binary alloy. The XPS results reveal the formation of a passive film composed mainly titanium and niobium oxides (TiO2 and Nb2O5). The Nb content has a great influence on the pitting corrosion resistance of these alloys due to the incorporation and the enrichment of Nb in the passive film.

This research has as its theme the study of the technical training integrated to the high school proposed by law 11.892 / 08 that created the Federal Institutes of Education, Science and Technology. Within this theme, we sought to understand the conceptions of integrated training of teachers working in the agricultural technical course of IFSP / Barretos, as well as the professional profile the course seeks to train, seeking to associate them with the predominant ideological tendencies. In this sense, the work demonstrated the existence of a dispute between the subjects about which educational emphasis should prevail in the students' teaching process. Through the research, a historical retrospective was also carried out in order to analyze the objectives of Brazilian legislators with successive reforms of the Brazilian educational system. Furthermore, the consequences of the reform of secondary education in the process of consolidating integrated training from the viewpoint of the local community, as well as the social movements and representatives of power, were investigated. For the construction of this work it was necessary a bibliographical and documentary analysis, besides interviews with representatives of the power and of social and / or academic movements. To understand how each teacher stands on the subject, the speeches given by the subjects were seen as statements. They were obtained through questionnaires and interviews applied in the second half of 2017. From this perspective, this work allowed a reflection on the role of the federal institutes in the construction of an integrated training beyond the duality training of labor or propaedeutic training. Thus, the work pointed to the need to create conditions for the theoretical-political debate on the presuppositions of an integrated teaching and its pedagogical developments.

This research presents a structural analysis of flat plates in reinforced concrete with the introduction of openings in regions established by foreign standards (ACI318: 14), whereas NBR 6118 (ABNT, 2014) doesn’t make any recommendations about dimensions and positioning of possible openings that may exist in the structural system. Firstly, a comparative analysis of the results was done using the analitic calculation methods (Direct Method and Equivalent Gate Method) and the Finite Element Method using the SAP2000® v.16 software on flat plates. In a second moment, the openings were introduced in accordance with ACI 318: 14 as the initial parameter for such design and used only SAP2000® v.16 software for analysis. The reactions of bending moments and transversal displacements caused by these efforts were compared, as well as presenting the required amount of steel and its distribution throughout the structure. 57 slabs were modeled with the purpose of verifying the coherence of the manual calculation methods and analyzing the influence of the openings on the flat plates system, presenting as variables the slab thickness, dimensions of the openings and their positioning. As a result, the study provides satisfactory conclusions regarding the maximum openings slab stipulated by ACI 318: 14 when comparing its efforts and displacement reactions with slabs without openings, beyond to be able to verify the behavior of the structure when inserting openings that exceed these limits. For the analysis of slabs without openings, it was possible identify distinct characteristics that each calculation method provided from its results.

In recent years, different technologies have begun to be used in educational scenarios, providing gains in the teaching-learning processes. Augmented Reality (AR), and more specifically Mobile Augmented Reality (MAR), is a technology that provides great opportunities in education, allowing to blend real-world elements with virtual information, giving the learner a richer environment and greater possibilities of interaction than their natural environment, still encouraging mobility. Aiming to foster the development of educational applications with this technology, frameworks and methodologies are necessary in such way that facilitate the development and guide the creation process trying to minimize the complexity. However, it is also required that created frameworks are specifically oriented towards education, and therefore provide functionalities that support educational needs (e.g. to support the use of questionnaires with questions/answers). Currently there are many frameworks for creating AR, however they are oriented towards the creation of generic, rather than specifically educational, AR applications. In this project, a framework is proposed to support a methodology for the development of educational applications with MAR based on markers. The framework allows developers to implement a set of education-oriented functionalities without programming, and instead drag and drop classes, creating and customizing scenarios with the required resources (3D models, images, etc.). The methodology is composed of guidelines to be followed in the development of the application. A case study was carried out to evaluate the framework, mainly regarding usability, additionally the framework was also evaluated through experiments with developers, and using questionnaires for data collection. Finally, through the experiments carried out, it can be concluded that the proposed framework can allow the development of educational applications of AR with ease, providing functionalities that are customizable according to the needs of the user, and of a general nature in education (useful in any area of education).

In this thesis, we investigated the microstructural development of BaCe0,9Y0,1O3-ẟ starting from aggregate-free submicrometric and nanometric powders. The differential of these powders is that synthesis occurred via solid-state reaction, compared to powders commonly used in the literature in the same size range. Nanometric particles were obtained by alternating steps of calcination with steps of grinding using isopropyl alcohol as dispersion media in a vibratory mill, and varying grinding time and load (weight ratio of grinding media/powder), with care to particle deflocculation, as well as keeping the grinding jars filled at only 50% of total capacity. The sinterability of compacts was surprisingly high, compared to literature reports, so that sintered samples with density higher than 95% of theoretical density were obtained at only 1200°C with dwell time of 10 hours. Literature shows that this degree of sintering is only achieved with the use of sintering aids. Systematic monitoring of microstructural development of the green compacts made with the different powders obtained in this thesis allowed the detection of a liquid phase appearing around 1200°C, which has not yet been reported in the literature. In green compacts with aggregates, the liquid phase was consumed in the densification of these defects so that macroporosity would remain even after sintering at 1600°C. In aggregate-free green compacts, the liquid phase aided to achieve high and homogeneous densification, mostly around the initial temperature of its formation. However, even after achieving high densification at low temperatures, higher ones are required in order to develop the microstructure in ways to reach adequate protonic electrical conductivity. The microstructure developed by powders obtained by grinding with 20:1 ratio (grinding media/powder) for 24h and sintered at 1600°C showed a proton conductivity of 2x10-2S/cm at 600°C which is in agreement with the best results in the literature.

Allocating or reallocating civil servants at a public institution of higher education is not an easy task. The working areas are various and balancing the institutional and personal needs is a major challenge for People Management organs. This research aims at studying internal reorganizations from 2012 to 2016, by public administrative technicians of the Federal University of São Carlos (UFSCar). The present study is characterized as a case study, with an exploratory and descriptive approach with quantitative emphasis, besides bibliographical and documental research and questionnaires as a technical procedure. A documental research of service reports published at the institution website and internal spreadsheets used by Pró-Reitoria de Gestão de Pessoas (ProGPe) for the reorganizations was carried out. The study has concluded that the major movement happened in 2015, with 75 reorganizations. Considering the workers’ profiles, it was identified that most of them are female and they are aged from 28 to 37 years old. They have been at the institution for less than three years of effective practice and have higher degrees than required for the position. In order to identify the most recurring reasons for the reorganization processes, a questionnaire was used with closed questions to 107 servants. It was possible to conclude that work overload and responsibilities’ excess are the major reasons for the reorganization requests, followed by relationship problems with manager/boss and dissatisfaction with the team and colleagues. Considering these results, this study aims at assisting a future People Management policy which could be more appropriate.

This thesis intends to observe the relationship between brazilian and foreign anthropologies, seeking the representation among it in the many senses that they may acquire. From the double “center-periphery” relations - between anthropologists and natives on one side, and central and marginal anthropologies on another- the research will seek to highlight the ways in which relations are established and their contents. In this sense, it will be necessary to see, among other elements, how certain "central" anthropologies dialogue with the Brazilian anthropology when its objects are in Brazil, At another level, we will look for definitions on the Brazilian anthropology in instruments such as encyclopedias, dictionaries and, mainly, periodicals. At this point, we intend to compare "outsiders" and "internal" views, produced, however, for a global audience, as a mechanism for observing the type of relationships that can be understood within vectors conceived by the "center-periphery" axis. How then could we observe the multiple positions that Brazilian anthropology occupies in the international field? The idea, therefore, is to build a typology of relationships that helps to think certain international politics about Brazilian anthropology.

This study describes the synthesis of a new library of prolyl peptides-lipopeptoid hybrids catalysts through a multicomponent combinatorial approach. For the design of this catalyst library, we took into consideration the growing interest in the development of environmentally friendly technologies and the recent contributions of our research group in their field. To this end, by using the Ugi-four component protocol we have incorporated lipidic side chains in the architecture of the proyl peptide-peptoid hybrid catalyst. The insertion of functionalities with amphiphilic properties afford to the organocatalyst surfactant properties. Therefore, they have been further evaluated as an organocatalysts in the environmentally friendly enantioselective addition of aldehydes to nitrostyrenes. The Michael adducts were obtained in high yields, diastereoselectivities and excellent enantioselectivities using low catalyst loading under water as solvent without addition of any other additive.

Pelvic floor muscle training is encouraged during pregnancy for the prevention of pelvic floor muscle dysfunctions. It is known that the contraction and training of others small muscle groups can cause changes in the autonomic nervous system (ANS) modulation, but this was not verified regarding the pelvic floor muscles (PFM). In pregnancy, cardiovascular autonomic responses to different stimuli may present differences in relation to non-pregnant individuals, due to adaptations of this period. Different analyzes and standardized stimuli provide complementary information on the functioning of ANS, which is not yet fully elucidated during pregnancy. This study consists of two manuscripts with the following aim: Study 1: To evaluate the response of the cardiovascular autonomic modulation to the postural change through different analyzes in the second trimester of pregnancy. Study 2: to evaluate if there is alteration in the cardiovascular autonomic modulation after the contraction of the PFM in pregnant, and if there is effect of the PFM training in the cardiovascular autonomic modulation at rest during pregnancy. Study 1 was a cross-sectional study where we evaluated the response of heart rate (HRV) and blood pressure variabilities (BPV) and baroreflex sensitivity (BRS) to postural change in pregnancy at the 18th week, and not pregnant women of the same range age. In study 2, we evaluated the HRV, BPV and BRS response after a series of PFM contractions in 18-week pregnant. The pregnant were divided into 2 groups, in which one performed PFM training from the 20th to the 35th week of pregnancy, and one control group without training. In the 36th week, HRV, BPV and BRS were compared at rest of the two groups. Conclusions: In study 1 we verified that HRV, parasympathetic modulation and BRS are reduced in pregnant at rest, while the complexity of HRV and BPV is maintained. The responses to postural change occur in the same direction with some differences, such as lower proportion in relation to vagal withdrawal and sympathetic activation. In study 2, we verified that there was no change in HRV, BPV and SBR after a series of PFM contractions, and that pregnant presented lower blood pressure (BP) and sympathetic modulation of BP, and higher BRS at 36 weeks of pregnancy compared to untrained pregnant women.

Marginal lagoons are considered an integral part of lotic systems, interacting with rivers through the exchange of water, nutrients and living organisms. They play an important role in the maintenance of biodiversity, especially the ichthyofauna, serving as a refuge for predators, nursery and feeding grounds. This work had as objective the characterization of the ichthyofauna of two marginal lagoons of a preserved section of the Paranapanema river, in order to validate the importance of these environments for the preservation of species of fish and their function as nursery and to record the basal frequency of micronuclei and nuclear morphological abnormalities in erythrocytes of the captured fish, comparing these frequencies with the control groups of other works of the literature. In general, the ichthyofauna sampled was composed mainly of small species, with low migratory capacity and life cycle associated to the marginal lagoons, depending on them for feeding / growth or reproduction. The disparities found in the communities of these lagoons in the different campaigns may reflect the degree of connectivity of these environments to the river; since the similarity between the lagoons was greater in the second campaign, which coincided with the beginning of the rainy season. The micronucleus frequencies and nuclear anomalies showed values similar to those observed in the literature for the negative control groups of the different species analyzed, evidencing that these lagoons can be considered little impacted by pollutants.

The process of physiological aging involves a series of alterations in the neuromuscular system leading to the reduction of mass and muscle force. Consequently, changes in muscle strength have been investigated in elderly individuals as a tool for detecting geriatric syndromes and declining functional capacity. Consequently, muscle force is routinely assessed in older adults as diagnostic criteria of some geriatric syndromes, and a tool for the investigation of functional capacity declines. However, unlike maximal muscle force, muscle force control indexes allow a better understanding of the neuromuscular system, providing information on the mechanisms governing force production and maintenance, reflecting the sensorimotor control of these individuals. However, several aspects remain uncertain in the study of muscle force control in the elderly. Thus, the effects of aging, muscle contraction intensity, and physical training on large postural muscles force complexity of remain unknown. Investigating these issues will have a great clinical relevance, allowing a better understanding of the age-related changes in the neuromuscular system and its responses to the multicomponent exercise program. In order to elucidate these aspects, this thesis was planned in 3 studies. The Study 1 entitled "Complexity of knee extensor torque: effect of aging and contraction intensity" aimed to investigate the effects of aging and the intensity of isometric contractions on the complexity of knee extensor torque. The results showed that although the knee extensor torque complexity is reduced in the elderly, its relation with the intensity of the contraction is similar to that of the young subjects. Study II entitled "Exercise training in older adults, what effects on muscle force control? A systematic review of randomized clinical trials" aimed to determine the magnitude of the effects of different modalities of physical training on muscle force control variables in older adults, through a systematic review of the literature. The results of this study showed that physical training has a beneficial effect on older adults’ muscle force control. Study III entitled "Effectiveness of a multicomponent training on muscle force control in pre-frail older adults: a blinded randomized controlled trial" aimed to investigate the effectiveness of a multicomponent training program in improving the functional capacity and the complexity of the torque of the patients. knee extensors in pre-frail elderly. The results of this study showed the effectiveness of the multi-component exercise program in improving knee extensor torque complexity and gait speed in pre-frail elderly.

In this work two topics involving symmetric and non-symmetric Schiff bases were investigated. In the first part, the mono- and trinuclear complexes of nickel (II) and copper (II) were studied as catalysts in the oxidation reaction of 3,5-di-tert-butyl-catechol. A variety of structures with yields above 58% were synthesized and characterized. Regarding the structures and properties obtained, the characterization data indicate remarkable differences between the mono- and trinuclear complexes. The series of structures allowed the possibility of evaluating and correlating the stereo and electronic effects with the catalytic activities of the compounds. The nickel (II) and copper (II) trinuclear complexes showed higher catalytic efficiency than their respective mononuclear complexes. Within the series of copper (II) trinuclear complexes, the 3-ethoxy substitution compound and two methyl groups [Cu(Cu(3OEtsaldmen)}2(ClO4)2] were found to be the most efficient. It has been found that there was an increase in catalytic efficiency with the change of substituents on the aromatic ring with the sequence -OH <-H <-OMe <-OEt. Furthermore, in general, by analyzing the effect of the methyl substituents close to one of the imines, the following order to the catalytic efficiency was found: -H; -H < -H;-CH3 < -CH3;-CH3, but depending on the substituent at the postion 3 on the ring, this effect was more or less pronounced. In the second part, three new complexes of type [Zn(ATI){N (SiMe3)2}] were synthesized, characterized and tested tested in the ring-opening polymerization of the lactones β-rac-butyrolactone and rac-lactide. The ligands, with two of them unknown in the literature, were readily obtained via a three-step synthesis from tropolone. The influence of the varying metallacycle ring size on the polymerization was evaluated. In situ IR measurements indicate a higher catalytic activity of the novel aminotroponiminate complexes for β-rac-butyrolactone compared with the β-diiminate system. The activity and degree of control were further improved by an in situ generated alkoxy initiating group generated after the addition of 2-propanol. An enhanced initiator efficiency allowed the synthesis of polymers with controlled molecular weights and narrow polydispersities. Furthermore, complexes with ethyl and isopropyl groups exhibited a high activity in the ring-opening polymerization of rac-lactide. Hereby, reaction time and initiator efficiency could also be optimized at a higher temperature or by the addition of 2-propanol.

This work describes in its first part the chemical study of the fungus Fusarium proliferatum looking for inhibitors of cysteine proteases, with two distinct approaches: i) The search for papain inhibitors, to understand the chemoecological interaction between plants rich in proteases and micro-organisms that can infect them; ii) the isolation of compounds that are possible human cysteine protease inhibitors. Nine metabolites were isolated, with beauvericin being the major compound in the extracts. This compound showed inhibitory activity against papain with IC50: 25.2 μM. In addition, beauvericin also showed inhibitory activity of two human cysteine proteases, CatV with IC50: 40.6 μM and CatB with IC50: 6.8 μM. In the second part of the study, synthetic compounds were evaluated for inhibition of cathepsin K. This enzyme is also a cysteine protease, papain-like, and is directly associated with the bone resorption process, where high CatK activity is related to bone diseases such as osteoporosis. Sixteen new synthetic compounds were evaluated, which presented moderate activities, low micro molar, against of CatK, using two approaches to search for inhibitors: i) inhibition of active site and ii) inhibition of exosites of enzyme. The compounds evaluated belong to three different classes, being epoxy-α-acyloxycarboxamide, epoxy-α-acylaminocarboxamide and quinolines phthalonitriles. An initial screening was performed to verify the activity of the inhibitors, then verified the potency of these inhibitors and the compounds that presented the best inhibitory activities were submitted to studies of the mechanisms of action. Molecular docking studies were also performed to understand the interactions between the protein and the inhibitor evaluated. The evaluated compounds showed moderate inhibitory activity, with the phononitriles being the ones with the highest potency, with IC50: 1.5 μM approximately. The compounds evaluated were identified as incompatible CatK inhibitors.

The Cleft Lip and Palate (CLP) are congenital malformations affecting the facial region, whose cleft or opening communicates the oral and nasal regions, causing air leak through the nose and hypernasalized voice. It is frequent in our population and the prevalence of one child per 650 births. The schooling of children is not well-explored scientifically and educational demands of these students have remained on the sidelines of the debate about inclusive education. Studies and research on CLP treat predominantly clinical, functional and malformat on rehabilitation aspects. This study questions: Do the sequels generated by the orofacial malformations, the long surgical and rehabilitation process by which a person with CLP goes through, impact directly their social relations, the development of the child and, consequently, their schooling process? This study aims at identifying the educational needs of the child with CLP in the schooling period that includes the early childhood education and the early years of elementary school and characterize the school experience of these children. To this end, three studies were carried out. Study 1- academic production on the child's schooling with CLP bibliographic survey to identify school-related aspects of people with CLP. Study 2 - sample characterization of children with CLP in age of initial schooling: survey using the medical records of the HRAC-USP. Study 3 - Children with CLP in school: their voices and the speeches of mothers and of teachers: children with CLP, their mothers and teacher were interviewed about the child´s school life. The results of the three studies indicated a shortage in academic production of studies on schooling of children with CLP in the school context. In relation to the sample of 300 medical records of the children, in the age group from 4 to 16 years of age, the research found out that the majority of the were male (61,3%), went through 3 to 4 surgeries, were white (98%), missing data on age/schooling gap. In the third study, the interview analysis revealed the participants' lack of knowledge about CLP; the satisfaction of mothers with the schooling and sociability of their children; at the same time, the difficulties of mothers and teachers to recognize the impact of FLP's consequences on communication and behavior of children, as well as the consequences for schooling, were identified. According to the results of the three studies, it can be inferred that there is still a lack of knowledge about schooling of children with CLP and its implications for school life, as well as limits of research in the educational literature on this population. With the present study, it was intended to bring the theme to the scope of the National Policy of Special Education and to the context of the schools. It is necessary, therefore, to expand the research in the area that contemplate this population, in order to fulfil the social role of the school to meet the diversity of students with a quality education and focused to meet the educational needs of all.

The current cotton culture model in Brazil is characterized by extensive agricultural areas, especially in the Midwest region. The mega-cotton system has been criticized due to the difficulties of conducting it sustainably. Modern varieties have been genetically improved to achieve high productivity and require greater amounts of fertilizers. In input-intensive crops, managed under a conventional system, the inappropriate use of mineral fertilizers increases the environmental risks and economic losses with fertilization, which represents 15% of the production costs of the cotton crop. The objectives of this study were: (i) to cultivate herbaceous cotton, variety IAC 27 RDN (80,000 plants ha-1), submitted to planting fertilization with mineral fertilizer (MF) and with organomineral fertilizer (OMF) (Cooperhúmus®); (ii) verify the effects of foliar application of fertilizer based on amino acids (Aminomagma®); (iii) evaluate biometric, nutritional, and production parameters. The experiment was conducted from 12/2017 to 06/2018, in a dystrophic Oxisol, with an experimental design in five randomized blocks and the following treatments: T0 - without fertilization; T1 - MF at planting (580 kg ha-1 NPK 04-14-08); T2 - MF at planting + leaf amino acids; T3 - OMF at planting (625 kg ha-1 NPK 04-14-06); T4 - OMF at planting + leaf amino acids. The quantity of fertilizers was calculated for the expectation of productivity of 2.5 t ha-1 of cottonseed and the covering fertilization was carried out with 175 kg ha-1 of MF NPK 30-00-10. Aminomagma® was sprayed at 57 days after emergency (DAE) and 82 DAE. The following were evaluated: plant height (PH, m) at 29, 55 and 89 DAE; weight of apples (WA, g plant-1), at 89 DAE; productivity (kg ha-1), at 180 DAE. The sampling of diagnostic leaves occurred at 96 DAE for analysis of leaf contents of N, P, K, Ca, Mg and S. The results were subjected to analysis of variance and, when significant by the F test (p <0.05), were deployed for comparison by the Scott-Knott test (p < 0.05). The leaf contents of N, P, Ca, Mg and S were adequate, but there was K insufficiency. The treatments did not interfere in the WA, in the productivity and in the leaf contents of N, P, K, Ca, Mg and S. The use of Cooperhúmus® at planting (T3) resulted in plants with greater height at the beginning (29 DAE) and at the end (89 DAE) of the vegetative stage of the culture. Aminomagma® promoted an increase in the final height of the plants only when mineral fertilizer was used in planting (T2), with a similar result to the isolated use of Cooperhúmus® in planting (T3). Planting fertilization with Cooperhúmus® is recommended because, in addition to resulting in taller plants at 29 DAE, which is important for establishing the plant in the field, and productivity similar to that achieved with conventional fertilization, organomineral fertilizer improves chemical, physical, and biological soil attributes and minimizes negative environmental impacts resulting from nutrient loss routes, due to its slow and gradual availability of the elements.

The literature in the theoretical-practical field of Social Skills Training has indicated a positive relationship between a well-developed repertoire of social skills and the quality of social and professional relationships. The profession of psychologist social in nature, as most of the work occurs via interpersonal relations, and requires from the professional an elaborated repertoire of skills and competencies to handle generally conflictive relationships. Considering that the management of social interactions is an essential part of a psychologists’ work, the social competence of professionals can be as important as their technical competence. Multimodal evaluation of psychologists’ social skills repertoire and social competence would help to identify important skills for the quality of the therapeutic process, considering their relevance to the interpersonal nature of psychologists’ work. Therefore, this research aims to evaluate the potential relationship between skills and social competence of Clinical Psychology trainees and the quality of the clinical care they after. In total, 27 students from a Psychology course, their respective internship supervisors in Clinical Psychology, clients and informants indicated by them participated in the study. In the fourth year of their graduate studies, a multimodal evaluation of the students social skills repertoire was carried out, including self-assessment and a peer evaluation using the Social Skills Inventory, a sociometric evaluation, interviews and behavioral observation in a structured situation like reality. In the fifth year of the program, the quality of the clinical services provided by the students was evaluated based on the formation of a therapeutic alliance with their clients, progress of their clinical cases, and supervisors’ evaluations of the students' performance during the care. The data were statistically analyzed using tests of correlation and regression. The results point to positive associations between communication skills, self-control of aggressivity and expression of positive feelings in the formation of an alliance with clients and based on supervisor evaluations. Negative associations were also found between social skills and care quality, especially for the ability to interact with unknown people, to praise others and to disagree with higher authorities. The data allow us to know which social skills are associated with indicators of quality of care, however, further work is needed to better investigate the students’ social competence. Considering the multidimensionality of social skills and the negative associations found in this research, it is suggested that other aspects of social performance need to be investigated, for example, investigation criteria and requirements for social competence via the amplification of these assessment measure are needed. The cultural values of each subgroup define very particular norms for interaction, which need to be made explicit to meet social competence criteria and establish successful relationships. Despite the limitations of this research, among them the restricted number of participants and the absence of specific instruments for the evaluation of professionals’ social skills and social competence, the relationship between social skills and the quality of care was evaluated. Future research on this issue will contributes to the improvement of information on the subject.

The problem of controlling the significance level of the FBST (Full Bayesian Significant Test) test is studied in the context of Bayesian models for density, thus, a Bayesian method is shown that works with density estimation estimation and how the FBST should be conducted in that situation with this method when it is desired to test if one population has certain density distribution or equality test of two populations. For this, a modified e-value definition is presented that is an alternative to calculate the FBST measure. At end a simulation study with different density distributions and analysis the power function of the test in cases of one and two populations.

The present study addresses an analytical look at the creative work of American director Terrence Malick, the modes of materialization of his technical-stylistic resources (photography, sound, assembly of plans, among other characteristics) that provide meanings beyond the semantic content of cinematography. As a particular way of constructing a film, we think about the way these features configure the characters and their actions, observing in how the dramaturgy is thought through the available bibliography, in order to problematize what are the possible potencies implied in the creation of a proper style of dramaturgy in contemporary American cinema. From the point of view of the observer, we seek to promote meanings that emerge from the interaction between image and sound, questioning in what measure this relation is capable of articulating a unity through the discursive fragmentation present in the work The Tree of Life, (2011), our main object of study. In this film, the narrative does not seem to contain a factual, but rather discontinuous, order of presenting itself in a way that can be understood as fragmented. Such a contingent feature transgresses the classical structuring of dramaturgy and opens space for a certain similarity to the surrealist universe.

Considering the current scenario where there is a growing pressure for industry to include sustentability in its inegotiable values, several companies have been investing in research and development of new, environmentally friendly, processes. In the focus of innovation there are routes with smaller energy and solvent consumption, and reduced generation of waste. In this context, the present study aims at evaluating the production of fumaric acid via fermentation; the compound is an intermediate currently obtained from petrochemical raw materials. The study was based on extensive bibliographic research about the types of micro-organisms capable of producing the chemical, and an appropriate kinetic model to describe growth and accummulation of product was chosen. As an adequate kinetic model was not readily available in literature, a simple model was adjusted in the software SimulaFerm using experimental information reported in articles. Then, the bioreactor model was implemented in Scilab environment, making use of constitutive equations (kinetic models), and mass balances pertinent to transient operation. This software was chosen due to its interface with the process simulator COCO (CAPE-OPEN to CAPEOPEN), which does not comprise in its basic unit operations batch reactions commonly present in fermentations. With the results obtained, it was possible to better understand the limitations and opportunities regarding the production of fumaric acid through this alternative route.

Itinerância Poética is a movement that seeks to promote encounters based on poetry. It happens through the komboteca that harbors a collection with more than a thousand books that, for the most part, are of independent production. Poetic Roaming traveled about 12,000 km, from Minas Gerais to Maranhão, through thewilderness, and from Maranhão to Minas Gerais, by the coast, with the main objective of occupying public spaces with public actions, strengthening local movements that already exist.This research presents, through the auto-ethnographic method, the importance of access to art for anyone who wants (to be able to produce it and / or to access it), the production of poetry (capacity to create and produce interventions in the world) and popular culture (the place of the common in the production of life, in the daily life) as determinants and conditioning factors to the health of individual and collective subjects, indispensable to the life. The proposal of this study challenges the place of the traditional clinic inviting the lector to think in broader perspectives, beyond the health-disease binomial, that is often understood as antagonistic states. It allows reinventing the concept of clinic asa space of engagement and co-responsibility with human suffering, through the construction of life possibilities and in the production of new subjectivities.
