The objective of this work was to develop methodologies for the determination of inorganic constituents in meat sample and the study of correlations between samples with chemical elements profile, especially Nelore samples of project BifeQuali aimed at improving the quality of Brazilian meat. Three different strategies for sample preparation, basic extraction, acid extraction and microwave assisted acid digestion were optimized and evaluated, by using bovine liver certified reference material (NIST 1577b), and the decomposition assisted by microwave radiation chosen for the decomposition of 650 samples used in this work. For the measurements of chemical elements, mass spectrometry and optical emission inductively coupled argon plasma (ICP OES and ICP-MS, respectively) were used. The chemical elements quantified by ICP-MS were V, Mn, As, Co, Ni, Mo, Cd, Pb, Cr, Se and Fe, by ICP OES were Ca, K, Mg, Na, P, S and Zn. The use of internal standard (Sc, Y and Bi) contributed to the accuracy and precision of measurements. For principal component analysis (PCA) was developed a worksheet to perform the spectral scanning, monitoring 250 wavelength from 167 to 770 nm using ICP OES. The results showed that the crop that is bred proved to be an important variable, forming clusters corresponds to the two crops analyzed, which indicates that climatic factors affect the profile of chemical elements and the quality of nutrition. Moreover, the place of confinement is also presented as an important variable, showing the grouping according to the place where it was confined. Through PCA and analysis using SAS software was possible to observe the correlation between Na and K with the tenderness, and the higher the concentration of these, the lower the shear force, and the higher the tenderness

Through the perception of the value and potential of Biotechnology for Brazil and the lack of studies concerning politics, economy and social affairs in this area, this research has the intention of studying the Biotechnology companies from the point of view of their information management and relationship with Financiadora de Estudos e Projetos (FINEP), major sponsor, based in the hypothesis that there might be some difference between companies that receive and companies that do not receive financial resources from FINEP regarding information and market position. The methodology applied can be defined as descriptive and exploratory, with quality and quantity analysis. The data was collected through the organization of secondary information and research in specific literature and official web sites, content analysis form and a questionnaire applied via websurvey to 52 biotechnology companies set as statistic sample. The analysis was based in simple statistic, reflected average and official announcements and free answers checking. The results obtained from the Brazilian biotechnology companies were in general geographic location and legal nature. Regarding the companies taken as sample, the results were: the companies managers graduation; geographic market comprehended by these companies; business size; their relationship with FINEP; identified obstacles to their development and information management uses and competitive intelligence executed. Besides these results, there is a resumed analysis over the FINEP official announcements with the identification of their main characteristics. The main conclusions shows that the FINEP official announcements have clear structure about the necessary items and means of evaluations applied, as well as a schedule for all the process. The FINEP and Non-FINEP companies have similar practices when dealing with information, including informal and non-coordinated actions. This reality can be one of the reasons that colaborate to a difficulty in elaborating proposals to FINEP for there is lack of good and appropriate information to develop adequate proposals. However, it could be noticed that the competition among the biotechnology companies is high, what tends to be linked to a market highly focused in innovation. Thus, theoretical constructions were integrated with the information obtained with the research, generating a simplified model of information management with recommendations looking forward to structuring the actions involving the informational practice in companies. It is expected that the results presented can strenghten the data collection of the companies as well as the use of information, promoting better decisions about FINEP and some perceptions to contribute the elaboration of official announcements to this area.

This study aimed to understand the meaning and motivation that exist in student participation in various extracurricular activities in public universities, particularly in undergraduate research and student organizations. The degree course chosen for this research was Electrical Engineering at Unicamp. A questionnaire was used, which was answered by 111 students, and in a second step, semi-structured interviews were conducted with 13 of these students. The topics covered in the interviews were: life trajectory; education in public universities; undergraduate research and student movements, focusing on the action of the Centro Acadêmico (CA) and the Diretório Central dos Estudantes (DCE). Other issues were a result of these themes, like the academic performance coefficient and the práticas in other student organizations, like Empresa Júnior, Atlética, Trote da Cidadania, Mercado de Trabalho em Engenharia and Solidare. The discussed analysis categories were: formative trajectory and life project; the meaning of the public university and the confluences with the life project; and the meaning of the student movement and different interpretations of student participation. The analysis was based on concepts of alienation, surplus-value, use-value and exchange-value and relations of production, proposed by Marx, and of alienation, estrangement, suspension, subjectivity, intentionality, teleological pose, possibility and alternative, proposed by Lukács. From the reports of students, one could note the competitiveness and individualism found at the university life, always in the midst of many contradictions. It is concluded that the meaning attributed to student participation in extracurricular activities, permeated by instrumental rationality of this universiy life, rests predominantly on pragmatism and utilitarianism, despite the occasional moments of resistance.

This study aimed to understand that childhood perceptions of black children are unveiled in the process of childhood education teachers. To this end, I present a brief reflection to contextualize my training black woman activist, professor of Early Childhood Education and researcher. Following aboard a history on the establishment of early childhood education affects a federal university in which research collaborators are working in recent years and has sought to develop a work to combat the distortions and inequalities experienced by black. The theoretical references were prepared from the position of rethinking and combat situations that marginalize and disqualify in this case black children, always from the guiding question: "What childhood perceptions of black children reveal kindergarten teachers from their experiences". References are presented in the theoretical understandings and insights into: totality, perceptions, horizon, early childhood education, experience, childhood education teachers, coloniality, children and childhood. The methodological approach was built with help and inspiration in the Phenomenology of the African philosophies. So I relied on three collaborators who are experienced teachers childhood education, they all have more than fifteen years of experience and proven commitment to the education of ethnic-racial relations. Data were collected through in-depth conversations, which were identified as the meanings and themes unfold the same units that are grouped in dimensions. Data analysis revealed the dimensions: the time a former, former to child education, experiences his own childhood, childhood black - deny and doubt, this black child, missing, racialized perceptions and feelings, and finally, black marks and white markings. That reveal the training of teachers is an ongoing process and as they learned the techniques of education for ethnic-racial relations, but also realize the childhood of black children stereotypically and Eurocentric. In the final considerations introduce the concept of time to educate and racial-ethnic relations, drawing some insights about the training courses for teachers, the specificities of early childhood education and questions about childhood understandings grounded in Eurocentric values. In this chapter, I highlight that black children who are the lead teachers to seek knowledge about black / as, however, of black children is perpetuated as fragments distorted by an atmosphere of racism and inequality.

Le sujet de cette thèse est l étude de nanofils de cobalt dans une matrice d oxyde de cérium (CeO2) épitaxiée sur SrTiO3(001). L auto-assemblage de nanofils a été mis en évidence lors de la croissance de couches minces de CeO2 fortement dopées au cobalt par ablation laser pulsée. Le caractère métallique du cobalt a été vérifié par des mesures d absorption X au seuil K du cobalt réalisées au synchrotron. La formation de nanofils a été mise en évidence par des études de microscopie électronique en transmission en mode haute résolution et en mode dénergie filtrée. Ces études combinées montrent la formation de fils métalliques de Co dans la matrice, orientés le long de la direction de croissance, de longueur limitée par l épaisseur de la couche et de diamètre dans la gamme 3-7 nm. Ces nanofils constituent des systèmes modèles en nanomagnétisme. Deux assembles de fils (diamètre 3 nm et 5 nm) ont été étudiées en détail. La structure interne des fils a été déterminée par microscopie électronique et le renversement de l aimantation au moyen de mesures magnétiques statiques et dynamiques. L anisotropie magnétique de ces systèmes a été sondée par résonance ferromagnétique. Ces mesures et leurs interprétations ont permis de mettre en évidence la localisation du renversement de l aimantation dans les fils. Ce phénomne de localisation a été corrélé à la structure interne des fils, plus précisément à l existence de grains hexagonaux au sein desquels l anisotropie magnétocristalline est en compétition avec l anisotropie de forme. L ensemble de ces résultats a permis de corréler le comportement magnétique à la structure interne réelle de ces objets.

In this work we will study the existence of nonnegative nontrivial weak solutions to singular elliptic equations involving the critical Caffarelli-Kohn- Nirenberg exponent and sign-changing functions. For this purpose, we will make use of the variational method and its classical results as the Mountain Pass Theorem and the Ekeland’s Variational Principle. We also will use the well known Nehari manifold.

According to studies developed by the Critical Theory of Society, particularly Theodor Theodor W. Adorno (1984, 1992, 1994, 1995, 2002, 2010), Max Horkheimer (1984, 1980) and Walter Benjamin (1970, 1984, 1985, 1987, 1989, 1992), the proliferation of the apparatus of the culture industry becomes, gradually, the formative experience increasingly scarce and superficial. The society of information is the same that nevertheless, imposes on its subject a condition of semi-formation to expropriate them the signs of interaction with the world, especially in the establishment of a form of instrumental language. In infancy, the formatting of the bodies through the school subject, which ignores the subjective forms of expression of the child, supports with the gradual curtailment of the possibilities of human emancipation. This research aimed to understand how multiple languages in childhood are decoded in the school environment as an unruly act, and to be repaired by formatting the children's bodies, so this practice relates to a semi-formative educational model.

Over the years, the task of developing and managing production systems has become increasingly complex and, currently, to face the changing customer demands and global competition, managers have the difficult task of combining the efficiency of mass production with customization of pre-industrial craft production era. In this context, the Engineering to Order Capital Goods Industry, exposed to a very adverse market conditions such as high cyclical instability of demand for its products, which depends exclusively on the economy expansion moments, causing, therefore, longer cycles of fluctuation demand with long periods of stagnation followed by periods of high demand, have sought for modern production management strategies, already consolidated in more dynamic segments of the economy, such as lean production and the theory of constraints, to improve production flow and minimize the impact inherent in these production systems with high variety and low volume production, high levels of work-in-process, functional production layouts, high varied workloads, excess of materials handling, etc. This paper studies the Engineering to Order Capital Goods Industry, especially large capital goods, also known as Large Assemblies production systems, aiming to propose a method of joint implementation of lean principles and theory of constraints to simplify the material and information flow, propose the use of suitable SCO (ordering systems) and reduce production lead time in this environment.

The objective of this work is to examine the use of Mossbauer spectroscopy in two aspects: the data acquisition, using four different setups and their analysis, comparing three different fittings programs. Concerning to acquisition, we showed that the adaptation of the Ortec MCS-32 system acquisition, to use not just 512 channels but as well 1024, 2048 and 4096 channels can improve the spectra quality. However, the time acquisition increases, proportionally to the increase of channels number. Four different samples were used in these tests, whose data were acquired using 512, 1024, 2048 and 4096 channels. The first and second samples analyzed, were two clay from Sta. Gertrudes region in São Paulo´s state -BR which had been treated in different conditions. Although the spectra resolution was better, in this case, we showed that the results quality are similar, independently of the channels number. The third one was pellet of iron ore, produced by Cia. Vale do Rio Doce . In this case, the use of 2048 channels data was suitable to identify a structure, not observed when less channels were used. It was propitiate as well by the fitting through the WinNormos for Igor. At last, we re-analyzed some spectra, acquired using 512 channels, from a previous study of our research group, on the AISI 316L stainless steel, applying the WinNormos for Igor. The spectra were fitted using the site plus field distribution model , conducting to better identification of the phases and their percent in the samples. The study and comparison of the three PC fitting programs showed that the WinNormos for Igor, is the most appropriate because its use is very simple, and permits much more flexibility on the fittings, making possible distribution on the different sensible parameters on the function used in the fitting.

The cerebral palsy (CP) due to a non-progressive lesion in the immature brain presents neuromotor impairments and disabilities associated who, allied with contextual factors such as task demands, environmental characteristics and attitudes of family members, can lead to impaired functional performance and the independence of children. Regarding to the actions of family members about the stimuli and expectation relating to children with CP, some studies reported differences between the assessment of family caregiver and the professional responsible for the children treatment and little is known about this difference of perception, being the understanding in the literature concerning aspects related to the way of thinking and acting of family members, still limited. This study aims to verify the agreement between the profile of functionality of children with CP reported by caregivers and rehabilitation professionals in the areas of self-care, mobility, social function and to identify variables related to the caregiver, child and environment that were associated with such agreement. We tested two hypotheses: caregivers and rehabilitation professionals disagree about the typical functional repertoire of the child with CP; and there are variables of the caregiver, child and environment, which may affect the assessment of caregivers in relation to the functional repertoire of his children, who are present when there is disagreement on this score between caregivers and professionals. The study included 50 children with CP aged from 3 to 7.5 years, their primary caregivers of 50 children with CP and 25 rehabilitation professionals, physiotherapists and occupational therapists, linked to six health institutions from the inside the State of São Paulo. The instruments Lipp´s Inventory of Stress Symptoms in Adults (ISSL), Social Support Questionnaire (SSQ), Gross Motor Function Classification System for Cerebral Palsy (GMFCS) and Pediatric Evaluation of Disability Inventory (PEDI) were used, beyond a form identifying the participants. The data were analyzed from the spreadsheets of each instrument and descriptive and inferential statistical analysis, and for the correlation 9 analysis was used nonparametric Spearman test and for the remaining analyzes, the Quisquare, Fisher s Exact, Mann-Whitney test, Kruskal-Wallis and Odds-Ratio. General Strong correlations were found, indicating agreement between the profile of functionality reported by caregivers and professionals, mainly in relation to functional abilities of children and caregivers support needed to the children perform the functional activities, with less agreement on changes of the environment that children use routinely. The relevance of correlations was influenced by factors such as: caregiver's marital status, family income, stress symptoms, professional guidance received regarding the activities of daily living of the child, caregiver time spent with the child and the level motor function of the child. Discusses that part of results does not support one of hypothesis of the research by distancing themselves from notes of literature, which indicate a convergence between the assessments of professional and caregivers, in the environment family and therapeutic, respectively, and a similarity of functional repertoire of children with CP in different contexts investigated, at same time as part of the results confirms the other hypothesis of study, when identifying factors that may explain the level of agreement between caregivers and professionals, configured as variables in this process. It is considered that, the present study may contribute by adding to the knowledge produced in the field, highlighting the influence of variables related to the assessment of caregivers regarding to functionality of the child with CP and interventions of occupational therapists and other professionals to be proposed with children and families in their developmental context.

The citrus industry faces serious problems represented by diseases that reduce the productivity and depreciate the fruits that give the appearance thereof. Among these diseases the citrus black spot caused by Guignardia citricarpa is one of the most important. As the predominant control of this disease is related to the chemical application, the financial costs, environmental and public health of these applications, as well as the increasing restrictions on the presence of residues in fresh fruits, and the possibility of emergence of resistant strains of pathogens to fungicides, it is necessary to study new control alternatives. Therefore, this work aimed to investigate the use of biocontrol agents, under field conditions, by applications of Bacillus subtilis, Trichoderma spp., uréia e combinação dos produtos comerciais Soil-Set® + Compostaid® on the citrus leaves that fallen to the ground, in order to reduce the production of ascospores directly and, indirectly, by acceleration of the decomposition of citrus leaves. The results of this work showed the viability of such applications as a help during the disease management to control of citrus black spot.

The drugs phenomenon is becoming more relevant in Brazil and worldwide in recent decades, reaching all levels of society. The frequent association between groups of youngsters, especially poor youth, and drug use, present in the media and in the public policies, has raised discussions and interventions that need to be analyzed and problematized in their propositions and development. Such interventions have not considered the socioeconomic and cultural situation that these youngsters are submitted, accumulating ineffective results. This data raises the need to take a "step back" in argument, reversing the order of the question and inquire, a posteriori about the best way to treat these young people in use or abuse of drugs - an issue undoubtedly relevant - and start asking first which are the social contexts and the social arrangements that put these youngsters in a vulnerable situation to the drugs issue and how this exposure occurs in their daily practices. In order to investigate how drugs make up the path of poor youngsters who live in outlying areas was undertaken a qualitative research that aimed to access the experiences of young people, between 15 and 29 years old, living on the outskirts of a medium-sized city in the State of São Paulo, which attending to a social institution dedicated to leisure, culture and sports activities. The methods applied to reach the aims were the participant observation, semi-structured interviews and workshops of Activities. The propositions of social occupational therapy constituted the theoretical background of the study. The use of participatory methodologies in the apprehension of the universe of subjects studied allowed accessing their perceptions about the drug issue, pointing out, however, other issues that permeate their daily experiences, determining their condition of vulnerability. Issues such as the constant violations of their civil rights; restrictions to urban mobility; social stigma; real and/or symbolic violence; the centrality of work and their links with and through the drug trafficking, emerged from the reports of these young people, enabling to build a picture of the extended social context in which they are located, indicating that, although present in everyday life, drugs are not the main source of concern or of increasing of the vulnerability of these young people.

This research project evaluated the changes in the fluxes of nutrients and metals at the sediment-water interface as a result of sediment treatment by the additions of PhoslockTM and calcium nitrate solution. The experiments were executed in situ using mesocosms that were assembled in the Ibirité Reservoir (MG). The calcium nitrate addition experiments showed nutrients flux abatement for Porthophosphate, ammoniacal-N and nitrate-N that were ≥ 90% whilst for the metals Fe and Mn the percentages reached 48 and 69%, respectively, as a result of sediment oxidation promoted by the intensification of denitrification rates. For the PhoslockTM addition the percentages of reduction in the fluxes across sediment-water interface was over 90% for P-orthophosphate and ammoniacal-N, 78% for nitrate-N and for the metals, Fe and Mn, 47 and 50%, respectively, as a result of the increased adsorption capacity of sediments due an excess of adsorbent material left on sediment surface.

The present work aims the study of electronic, elastic and structural properties of a whole class of nanoscopic semiconductors systems, which include quasi-two-dimensional, one-dimensional and zero-dimensional confined systems. Within two-dimensional systems, the effects caused by strain and temperature on the electronic structure of AlGaAs=GaAs multiple quantum wells oriented along [001] and [113] crystallographic directions were studied. The energy difference between light- and heavy-hole states as a function of temperature, for both crystallographic directions, was obtained from photoluminescence spectra. Using k _ p calculations, it was possible to phenomenologically explain experimental data and to show that electronic structure of quantum wells grown along [113] direction presents higher sensitivity to temperature variation. A second task in quasi-two-dimensional systems was the study of the magnetic response of neutral excitons in AlGaAs=GaAs simple quantum wells grown along [110] crystallographic direction. The Zeeman splitting and the degree of circular polarization (DCP) for the sample was extracted from circularly polarized photoluminescence spectra. Using k _ p calculations, it was possible to show that the valence band presents a high hybridization of spin states in this kind of system. To simulate the relative occupation of hybridized states, a dynamic model for spin relaxation combined with electronic structure calculations was performed. Based on theoretical results, the experimental data of the Zeeman splitting and DCP were satisfactorily and phenomenologically explained. As the last task in quasi-two-dimensional systems, the effect of in-plane magnetic field in a AlGaAs=GaAs double quantum well system was studied. As the main result, the envelope functions required for an efficient k _ p calculation in this kind of system was constructed. Concerning one-dimensional confined systems, structural properties of a twin-plane superlattice in InP nanowires were studied. The system was simulated along [111] crystallographic direction by molecular dynamics. The latter provided, besides nanowire atomic structure, stress tensor elements and elastic constants at T = 0 K. Giving the molecular dynamics results, it was possible to theoretically calculate strain tensor components and the potential profiles at the valence and conduction energy bands. The calculations showed how the strain potential profiles modulate the electronic band structure of the nanowire, generating a one-dimensional superlattice. Finally, within zero-dimensional confined systems, dynamic effects detected in the time-resolved emission from InAs quantum dots ensembles were studied. To explain the experimental behavior of the time decay as a function of quantum dots emission energy, the electron-phonon interaction, considering Fröhlich Hamiltonian model, and a carrier dynamics, that takes in account nonlinear effects such as carrier imbalance, were included in theoretically calculations. The theoretical results show that, when the system behaves like an ensemble, collective effects predominate, and different relaxation processes stand out in the system, distinguishing it from that one of isolated quantum dots. By means of theoretical calculations it was possible to satisfactorily explain the experimental data.

The units of information can be considered the repository of knowledge to their institutions as they appease the right to access information along with documentary record. By assisting the development of the Research and Extension activities at Federal Institutes of Education, Science and Technology, this research aimed the investigation and propagation of the importance of a unit of information in the Science and Technology strengthening. The chosen methodology for the theoretical and applied research was qualitative. Its approach was sociocognitive and implemented through questionnaires as well as the realization of the Group Verbal Protocol. Three units of information from the Federal Institute of São Paulo (IFSP) were analyzed, that is, the campuses of São Paulo itself, Garulhos and Salto. The chosen methods were: the realization of a bibliographical survey as theoretical support; the realization of a survey concerning the campuses and their respective units of information; the application of questionnaires and the use of the Group Verbal Protocol technique through the involvement of its participants, that is, management, professors, students, librarians and institutional partners from each campus. Some. The result, achieved through the application of questionnaires, was the socio-historical organizational characterization of the units of information from the IFSP. Some results achieved through the application of the Group Verbal Protocol were the following: the IFSP libraries have primary infrastructure and are still at an early stage. They require systemic structuring; the IFSP libraries do not support the Research and Extension activities which are developed in their campuses; the inexistence of projects derived from the units of information of the various areas in the Research and Extension field; the lack of exchange and partnership among the units of information themselves and other IFSP departments. The findings of the achieved results show the necessity of a greater autonomy, notoriety, visibility and institutional awareness about the importance of the units of information in the socio-educational context of the IFSP. The growth and development of Science and Technology are a pretension and part of the IFSP policy. Therefore, the units of information could spur this growth by truly acting as a repository of scientific, technological and social knowledge.

In recent years, the technology animal cells culture has allowed the development of many byproducts, especially those with pharmacological interest. Some of these products, the recombinant proteins, can be produced by heterologous expression systems on a commercial scale. Bacteria, yeast, mammalian cells and insects are some of the hosts used in these processes. As source of proteins with farmacological interest, the catterpillar Lonomia obliqua hemolinph was demonstrated to be a helpful organismo. Antiviral, antiapoptotic, antimicrobial and inducing growth proteins, are some of examples. Since the control of viral infections is a major interest to public health, the searching for new antiviral drugs has utmost importance. Several studies have reported the presence of active principles in the arthropods hemolymph. Recently, we demonstrated the existence of an antiviral protein in the hemolymph of the caterpillar Lonomia obliqua. This purified protein induced viral production reduction (TCID50 mL-1) over 157 times in cells infected with the measles virus, 61 times for polio and 61 times for influenza virus H1N1 infections. Thus, the present goals were building and expression of a recombinant plasmid contained coding sequences for expression of viral proteins (using baculovirus) in insect cell Sf-9 system. By this process, it was aimed to test biological activity of the protein. Further sequence analyses of this protein were performed using bioinformatics tools. The RNA of L. obliqua was extracted with Trizol reagent. RNA product was used in RT-PCR reactions with primers specific for the antiviral protein, based on the sequence of the cDNA libraries of L. obliqua tegument and spines, using all possible frame of translation for each cDNA. Restriction sites were inserted in cDNA sequence to insert it in pFastBacTM1 donor vector (Invitrogen). The sequence contained in selected clone of Escherichia coli DH5α was used for transformation into E. coli DH10Bac to obtain a bacmid by transposition process. This bacmid was used for antiviral recombinant protein expression in Sf-9 cells. This recombinant protein activity was tested in Picorna (EMC enchephalomiocardite), Rubeola and Herpes virus. In these trials, it was observed a replication reduction of 10,000, 10,000 and 1,000000 times, respectively. The bioinformatics analysis demonstrated that this protein is secreted, globular and probably belongs to a new class of proteins.

The Construction Industry is major generator of waste and use of natural resources and, therefore, while important to the economy, is causing enormous environmental impact. Regarding the generation of waste, its impact can be minimized with reduction actions at the construction site and measures of reuse and recycling. In 2002, at the Federal, passed Resolution No. 307 of the National Council on the Environment - CONAMA - which provides guidelines, criteria and procedures for the management of construction waste, in effect as of January 2, 2003. This study aims to determine the current situation of implementing the directives of this resolution in São Carlos, from the perspective of the responsibilities inherent in the companies operating in this city. For that we adopted the strategy of case study as a research method, with a structured questionnaire for use in major construction companies active in the city of São Carlos. The methodology comprised the following stages: a literature review on waste generation, structuring the questionnaire, the questionnaire was applied to a number of companies operating in the city of São Carlos and analysis of results. As a contribution stands out the diagnosis on the implementation of guidelines and procedures recommended in CONAMA Resolution No. 307 in the city of São Carlos, emphasizing the difficulties and possible ways for this to be actually applied. The results, in summary, show that employees are directly linked to the practices of construction do not know precisely, which describes the CONAMA Resolution No. 307 and construction companies, despite having practiced some activities related to the management of construction waste, not apply the concepts of law.

Fine motor coordination is essential to the intellectual and psychomotor development of a child. The use fine motor skills to manipulate objects and perform functional needs plays a vital role in child development and participation in activities of daily living. Therefore, difficulties in fine motor skills affect school performance and undermine the child s self-esteem and the sense of competence. The objective of this study was to describe how is configured the scientific field of fine motor skills in children national and international databases. In addition, aimed at specifics to analyze the scientific parameters in bibliometric, mapping scientific production within the fine motor components related to body function, participation in activities and environmental factors. The methodology used was bibliometric analysis of the studies recovered on the databases national and international, Banco de teses da CAPES, BVS, ScienceDirect and Scopus. The methodological procedures of the study were divided into the following steps: Step 1 - Review of the literature on Human development, Child Development Motor, Occupational Therapy and Information Science, Step 2 - Data collection and systematization of data; Step 3 - Bibliometric analysis: organization and processing of bibliometric studies collected using the Vantage Point software for bibliometric analysis and MS Excel for graphing and tables for data presentation; Step 4 - Description and analysis of results, recovering the concepts exposed in the theoretical framework on which to base analysis and interpretation of data obtained. At the end of the tudy produced the following bibliometric indicators: the Banco de Teses da Capes the year of greatest production was 2002; the gender of the authors and supervisors who emphasize was the female; the formation of the majority of authors in the field of Physical Education and Physiotherapy; most studies are at Master's level; The University has more studies in the area is UDESC, in the program graduate of Human Movement Science; the funding agency that funds most work is the CAPES; majority of studies are descriptive; the scale is the most used is EDM (Rosa Neto, 2002), the theme more approached is Motor Development; and the studies perspectives have focused functions and structures of the body. Regarding the databases BVS, ScienceDirect and Scopus, the publications have grown over the years, especially 2010; with most records are of collective authorship; the formation of the authors is in Occupational Therapy (33%), Physiotherapy ( 19%) and Physical Education (15%); the predominant language is English; in BVS in the country that indexes articles is Brazil; ScienceDirect and Scopus is in the U.S.; Periodicals that stood out in the BVS was Journal Themes About the Developing; ScienceDirect was Human Movement Science, and the Scopus were Developmental Medicine & Child Neurology (8%), American Journal of OccupationalTherapy (7%) and Physical and Occupational Therapy Pediatrics (5%); and the perspectives of studies have recovered the subject of fine motor anchored in the concepts of structure and functions of the body in three bases (56% - BVS, 69% - ScienceDirect, 71% Scopus); most studies are crosssectional nature (94%) and descriptive (81%); the topics most discussed were: fine motor skills (75%), motor development (35%) children (28%), preschool (27 %) and rating scales (21%); the data collection instruments more used in the articles were tests of fine motor skills not standardized (22%), followed by Scale Peabody (12%), test of motor proficiency of Bruininks-Oseretsky (7%) and M-ABC (7 %); identifies the subject of fine motor related especially with motor development (7%), autism (5%), prematurity (5%) and school context (5%).

The seminar, a discursive activity predominantly oral and a literacy practice, is a genre of discourse usually used in the academic community as a method of student assessment, which receives peculiar shapes, according to the area of knowledge that it takes place. In this context, first-year university students often participate in this activity intuitively. Based on the social-interactionist and socio-rhetorical language studies, and through qualitative research method we followed the oral presentations of new incoming undergraduate students, who belong to three distinct areas of knowledge (Agricultural Science, Exact Science and Humanities Science) of a public university in the State of São Paulo, with the purpose of examining how university students acquire the discursive seminar gender. By the analysis of audio and image recordings of the students‟ presentations, semi-structured interviews withteachers, field notes and journal, we concluded that students acquire this discursive activity based on oral presentations previously known or following other literacies practices presented in the academic context.
