In this work we seek to establish a first contact with Geometric Analysis, aiming the understanding of the Good Shadow Principle of Fontenele and Xavier ([FX11]), which is a generalization of the Omori-Yau Principle. We will expose the basic results that are needed for their comprehension, and extend the study to other topics of Geometric Analysis, as the heat kernel, the existence of exhaustion functions and estimates to the gradient of harmonic functions and subsolutions of the heat equation. Once understood the Good Shadow Principle, we intend to extend it by proving that the class of the second order uniformly bumpable manifolds, introduced by Azagra and Fry in [AF10], also satisfies this principle.

The Atlantic Rainforest, which has the title of World Heritage by UNESCO, is a very important area that must be preserved for its rich biodiversity, in addition to the natural and cultural assets that attract tourists. For all these reasons has considerable tourism potential and can contribute to the region's economy. The Design of Development of Ecotourism in the Atlantic Forest region was created to implement actions that benefit the communities surrounding protected areas, as well as broaden the infrastructure for the visitation in order to establish an orderly tourism management to avoid negative impacts on the region. This study aimed to evaluate this project from its conception to the end of their actions in 2012, especially its indicators, applying the methodology PDCA (Plan, Do, Check and Act). In its seven years of implementation and with the constant changes in park management and technical project, it is important to make a study and review of the activities and present the work done. Of 9 indicators, 4 achieved the target and the rest are close to reaching. The increase in the amount of published normative instruments and value in the income earned on the rise present a breakthrough for the Protected Areas. For the Bank, the results were positive; they were paid 98.15% of the total contract value. Moreover, due to the dollar variation, investments were canceled. For managers of parks, the balance was also positive for the gain with environmental education and improvement tools in the infrastructure to receive visitors. The activities carried out in the Project caused the state to be in inducing paradigm change in relation to the parks because: plus space for research, public visitation shall receive investments in order to increase the number of visitors but also improved quality receptive, which causes change in participation around. This change is characterized by a qualified participation of traditional communities, local businesses and the municipal government.

After a short resumption of Bergson s thesis about the inadequacy of language s expression of reality, which permeates all his works, this dissertation intends to discuss how Matter and Memory contemplates a deeper reflection on this subject as it presents the notion of motor mechanism , allowing to foresee the bodily grounds of practical habits and pointing out the problem of their transposition to speculative thought without criticism. In general, we intend to comprehend how Bergson s language conception based on a definition of word as an entity of motor order or more specifically as motor mechanism announces an extralinguistic access to reality when it directs the philosophical study to the notion of image and to the five figures which permeates the last chapters of Matter and Memory.

Polytetrafluorethylene (PTFE) is used in a wide range of critical applications because of its outstanding chemical and thermal resistance, low surface energy and special tribological properties. Because of its ultra high molecular weight, which leads to high melt viscosity, PTFE cannot be processed by traditional extrusion and injection methods. Cold pressing followed by sintering above its melt temperature is the main processing technique. The sintering time is defined according to the dimensions of the manufactured part and may last from a few hours to several days for large parts. Studies of the influence of sintering time and temperature on PTFE crystalline microstructure and mechanical properties are scarce in the scientific literature, being the main objective of this study. PTFE plaques were isostatically pressed and sintered at temperatures from 360XC and 390XC for times between 10 e 10:000min. Differential Scanning Calorimetry (DSC), measurements of mass loss and density, Scanning Electron Microscopy (SEM), compression and tensile tests were performed. The results of mass loss demonstrated that degradation is more pronounced in the surfaces of the PTFE parts and increases with sintering time and temperature. Analysis of the enthalpies of fusion and density measurements indicated indirectly the reduction in the molecular weight and increase in the crystallinity degree with increasing sintering temperature and time. The SEM analysis allowed the direct observation of crystalline microstructure, indicating a trend of increasing of the width the crystalline lamellae with sintering time and temperature. Tension and compression tests have shown that even under a wide range of sintering conditions, for which the polymer molar mass, crystallinity degree and structure are modified, PTFE mechanical properties are not significantly affected. The results obtained will guarantee PTFE parts processors and users to rely on polymer performance, even for parts exposed to extreme sintering conditions, current found in the industry.

In order to assist the institutions of science and technology to obtain actionable information for use in strategic processes and innovation, this research proposes a systematic, based on the practices of Competitive Intelligence to verify in an area of knowledge, which are organizations that can help in their research and development by mapping them and analyzing their scientific and technological profiles. The difference of this research is in this systematic emphasis on the recovery process of technological information. This process should be more rigorous, or even better investigated because, when not applied correctly can result in a skew analysis, compromising the information production. To develop a systematic methodology adopted was the case study, choosing Embrapa Instrumentation for the application. This institution was chosen because is a unit of EMBRAPA (Brazilian Agricultural Research Corporation, which actively participates in innovative practices in agribusiness and intelligence. The systematic was developed in the area of instrumentation applied to agribusiness comprising four main processes: a) identification of needs and categorization of activities; b) planning; c) mapping the organization and retrieval of information; d) analysis of the scientific- technological profile and classification organizations. The results were: a) a systematic of mapping and analysis of scientific - technological profile; b) the main organizations with potential contribution in research and development activities of the institution of study; c) the scientific - technological profile of each organization; d) the positioning of these in the agro-industrial system e) the key organizations, specifically, that acted more broadly in the categories of research and development of institution of science and technology. It is evident from the results that the objective was achieved contributing to the bottleneck that exists in the literature about recovery of technological information and providing actionable information to the institution of science and technology to understand your context of operation. Universities Nanjing University, Zhejiang University, Beijing University of Technology and the Company Sinopec were identified as key to the institution of study organizations. The development and implementation of systematic contributed in so far as possible the replication of this research in other areas, at other times, to other institutions of science and technology, and foster studies of other authors in order to promote improvements in the systematic, particularly in the process of technological information retrieval.

The research, based on the Sociology of Education, had, by goal, to understand the role played by the old Secondary Normal School of the city of São Carlos, in the constitution of a local leverage of intellectual elites characterized by a socially valued in the city lifestyle, during the period from 1911 to 1923. The research, through primary sources, rebuilt the relationships established between the school and the city, pointing out the symbolic elements of leverage / knowledge that determined the formation of the old Normal School, as a field of leverage propagated by cultural differences, disseminated within the daily relationships established in the city. As a category of analysis, was used the concepts of field, symbolic leverage, cultural capital, elite education and habitus from Education Sociology of Pierre Bourdieu, and also the concept of elite, according to authors like José Murilo de Carvalho.

In the product development process, user-related issues have achieved increasingly more relevance as they are progressively being perceived as strategies for innovation and competitiveness. In defining product specifications, designers strive to meet user needs. However, in real-use situations, a number of variability factors will result in gaps between what was anticipated by designers and actual user activity (DANIELLOU, 2002). This research was deployed during a laundry machine development process. The aim was to understand the existing gap between the designer model and the user model with regard to laundry activity, as well as user strategies to circumvent these gaps. Starting from the assumptions in Situated Ergonomics, we applied the activity analysis method. The results presented multi-determinants of the design process, such as: market needs; user knowledge; deadlines; financial resources; and project team member expertise. These determinants influenced the drafting of usage requirements, which, in real-use situations, reflected some gaps between designer and user models. Field research uncovered user strategies, such as: resorting to other information sources; creating new ways of use in line with user habits or interaction conditioned by their environment; and ignoring product functions they did not understand. This study's contributions relate to the importance of activity analysis in the design process and the role of the ergonomist in product design.

About 70% of the area cultivated with sugarcane in Brazil are on acid soils, characterized by having severe limitations in terms of fertility. Organic acids from residues decomposition of sugarcane, due to mechanized harvest without the use of fire, are able to interact with elements of the soil solution. This research project was aimed at investigating the influence of the addition of plant extracts residue of sugarcane in the complexation of Al phytotoxic and expansion of the root system of the crop . The experiment was conducted in laboratory and greenhouse, with the following specific objectives: (a) characterize chemically and determine qualitatively and quantitatively the organic acids present in plant extracts of the residue of sugarcane harvested mechanically to select the plant extract with greater neutralizing capacity of Al; (b) test doses of plant extracts of of sugarcane for complexation of toxic Al; (c) determine the depth of root development of varieties of sugarcane under conditions of high Al saturation; (d) verify that the plant extracts applied on columns filled with soil naturally acid, cultivated with sugar cane were able to promote the elevation of the pH of soil. The results of laboratory analyzes of plant extracts showed greater power to carry exchangeable cations along the soil profile and neutralizing Al phytotoxic to the plant extract of the residue variety RB867515. The results of the experiment at home a greenhouse indicated that the varieties of sugarcane differed in Al tolerance of the soil, on the accumulation of biomass and aluminum aerial part and root system, as well as deepening the roots. The plant extract residue of variety RB867515 had a positive effect on root development of varieties, in raise soil pH, alleviating Al toxicity and the availability of basic cations to the sublayers of the soil columns. The dosage of the plant extract, which promoted effective improvement in soil properties, was the equivalent of 21 tha- 1. The varieties were classified as tolerance to Al, as follows : RB966928 > RB855453 > RB867515.

Reactive oxygen species (ROS) are produced by the organism under various circumstances, such as the incomplete reduction of oxygen during cell respiration and also by exogenous factors. Have certain roles in the body, however, when in excess are harmful causing lipid peroxidation, DNA damage, cell organelles and even death. So, cells have developed antioxidant systems to maintained ROS at an appropriate level. Participating in this system the antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase and peroxiredoxins (PRDX). The latter stands out for its great abundance and reactivity with substrates, in humans six PRDX were described and are located in different cellular compartments, developing important roles in cell signaling and protecting cells from oxidative damage. In erythrocytes, this protein is so abundant that only lost in concentration for the globins, indicating a probable key role in this cell type as the erythrocytes are true targets of damage caused by ROS. However, little attention has been given to the antioxidant role of peroxiredoxins in erythrocytes and there are few studies in the literature relating to some of these proteins with erythrocyte various diseases, especially in relation to haemolytic anemia, which are part dehydrogenase deficiency Glucose-6-phosphate (G6PD) deficiency whose production of NADPH appears to interfere with the catalytic cycle of peroxiredoxins, however the relationship of these proteins in G6PD deficiency and SC hemoglobinopathy has not been explored. Literature data show that the erythrocytes in patients with sickle cell disease are under constant stress, in the case of individuals with SC hemoglobinopathy seems to be a greater rate of autoxidation of hemoglobin due to instability of the hemoglobin in this disease, leading to increased ROS. Then, this study evaluated the role of PRDXs in reticulocyte of patients with diseases described above, compared with reticulocytes of healthy individuals, using real-time PCR and Western blot. The results showed that no significantly statistical difference between the gene expression of PRDX in control and in patients in the two diseases studied. As for protein expression apparently there was also no significant difference. However, when assessing the redox profile at the major PRDX found in erythrocytes, PRDX 2, along with PRDX 1, we found that these patients were more oxidized state in patients than in controls. This suggests that there is a deficiency in the recycling of these proteins due to low activity of thioredoxin reductase, also due to increased ROS in these patients. And as patients do not present a severe hemolytic anemia there may be an increased expression and/or activity of other antioxidant proteins such as glutathione peroxidase and catalase.

Due to increasingly irrigation water source scarcity, treated wastewater (TWW) is becoming a more attractive by nutrients source, showing sanitary and agronomics feasibility. In this way, this research evaluated, in a greenhouse conditions influence of superficial drip irrigation on radish (Raphanus sativus L.) cv. Crimson Giant production and nutritional status, as well as, soil chemical attributes changes; and, soil and radish sanitary contamination risk submitted to two water sources. The experiment was carried out at CCA/UFSCar, Araras, SP and a completely randomized design was adopted, with two treatments [AB- potable water (PW) and AR- treated wastewater (TWW)]. Soil and radish sample were submitted to sanitary analyses. The results showed that drip TWW didn t commit radish nutritional, production and increased macronutrients availability. However, soil sodium adsortion ratio (SAR) and exchangeable sodium percentage (ESP) increased by TWW application, but without salinization and sodification risk. Furthermore, radish showed out of sanitary conditions, indicated by the E. coli and total coliformis contamination, impossible its commercialization and in natura consumption. Considering the obtained results, suggest take appropriate action to improve the TWW treatment efficiency and promote radish sanitary conditions. The obtained results demonstrated the wastewater reuse feasibility as a source of nutrients to radish, substituting or reducing the application of commercial fertilizers and reducing the cost production.

In the present research, we analized the pedagogical proposal from the learning system of SESI/SP, implanted in the educational web of the city of Araraquara, inland São Paulo. The four books to teach Science recommended by this proposal, used in the 6th to the 9th years (children aged 11 to 14, secondary school) were also analyzed both analyses were made by an investigative perspective. We searched to verify the consonance and coherence between the fundaments of the Proposal and what is executed in the books in terms of this proposal. The methodology used to orient this research was the analysis of the content. First, we investigated the fundaments of the Proposal in three dimensions: how the school curriculum is organized, what the teaching concept for Sciences is and how the investigative perspective works these topics made us capable to analyze the consonance between the Proposal and the activities of the books. Later, we characterized and quantified every each activity according to the categories of analysis created under the base of the aspects present in an investigative teaching approach. The created categories were: proposal of problems, formulation of hypotheses, observation of phenomena and objects, collecting data, interpreting data, elaboration of conclusions, systematization and socialization of the results. We also investigated the degree of openness provided by the book to the students, according to the previous categories. The data was organized through charts and the confection of evaluative cards, and when it was interpreted by these tools, it has allowed us to know better about the Science teaching approach transmitted in this material. The results indicate consonance between the Proposal and the material, although some considerations must be made about it.

The theme of this study is the indexing policy for Coordination of Social Communication (CCSs) in university environments, focusing on indexing clippings. This theme is based on interdisciplinary characterization existing between Science, Technology and Society (STS), Information Science (CI) and Communication Sciences (CC) fields in the context of the area of Knowledge Organization to combine, share and create mechanisms that society closer to the aspects of science and technology. Regarding Social Communication highlights the use of clippings, many organizations and this instrument is appropriating to select news in various media on subjects that interest them. Therefore, the purpose of this research is to investigate the organizational and communicational reality CCS/UFSCar, as a starting point for further studies in order lifting guidelines for establishing a policy of indexing for CCSs from context and Analysis Representation of Information. With this proposition, this research has the objective to contribute to the establishment of a policy index that optimizes the thematic treatment of clippings from the perspective of CCSs in university environments in the context of social cognitive indexer professional clippings and users who retrieve this product informational, from theoretical and methodological foundations provided by the area of Knowledge Organization. The qualitative method was used for theoretical and applied research with socio-cognitive approach, and gave up from the questionnaires and the application of Verbal Protocol Group. The methods used were: application of technical and organizational questionnaires and using the technique of Verbal Protocol Group, involving participants: directors/responsible CCSs ANDIFES linked to the brazilian federal universities; director and indexer CCS/UFSCar as well as users who clippings recover the system used by the unit. The results obtained from the questionnaires was the technical-organizational and socio-historical characterization of CCSs from brazilian federal universities and CCS/UFSCar. Mention some results obtained from the application of Verbal Protocol Group in the form: there is a concern with the procedures used to perform the indexing, there is not a satisfactory representation of the matters contained in the indexed clippings; participants suggest that the retrieved records arranged and are also available by publication type, the recognition by participants in relation to the function of preservation and institutional memory that performs clipping, and no need for a policy of indexing and his record in a manual indexing for CCS/UFSCar. The final consideration from the results obtained that depict the existing interdisciplinary STS, CI and CC fields enables collaboration scenario of theories, methodologies and practices for establishing a policy that involves the entire process of thematic information processing and, consequently, quality in both storage and retrieval of.

In Brazil and other countries the agrochemical carbofurano is largely used, and can reach freshwaters and cause damages to non-target organisms. Rotifera dominates zooplankton communities of most freshwater ecosystems worldwide, both in number of species and density. In the present work biological and ecotoxicological studies in laboratory were carried out with the species Philodina roseola Ehrenberg, 1830 (Rotifera, Bdelloidea) regarding the main aspects of its biology: life cycle, filtration rates, ingestion and secondary production at 25 ± 1.0 °C, besides testing its sensitivity and performance as a test-organism for ecotoxicological studies. Also, a literature review regarding the use of rotifers as testorganisms in the evaluation of pesticides toxicity in freshwaters was carried out for the last three decades. Experiments were performed aiming to assess filtration and ingestion rates of P. roseola feeding on the microalgae Raphidocelis subcapitata at 7 different concentrations. The individual biomass (μg DW ind-1) and secondary production were determined. The main parameters obtained for P. roseola life cycle were: 23.88 ± 3.82 hours duration of embryonic development; 3.5 days generation time; 22.33 ± 2.29 eggs/female total mean fecundity and 23.0 days maximum longevity. Filtration rates varied between 2.715 and 6.615 ml ind-1d-1. Total mean individual secondary production was 0.285692 ± 0.055185 μg ind-1d-1 from which 73.42 ± 5.62 % was allocated into reproduction. P. roseola was an adequate test-organism for ecotoxicological studies considering the life cycle characteristics and response to the pesticide carbofurano with CE50 48-h values of 13.36 ± 2.63 mg L-1 and 89.32 ± 6.52 mg L-1 for the active ingredient and the commercial product, respectively. It was concluded that P. roseola has a fast development time, high metabolism as related to ingestion and filtration rates, high fecundity and moderate sensitivity to the tested pesticide. Studies on its functional response to other factors combinations and sensitivity to other toxicants should be performed.

The rural development in the Brazilian South and Southeast started in the mid-eighteenth century, initially by mining and later by coffee and sugar cane crops. Besides the economic development, the architecture and culture are highlights from these regions. In order to describe tangible and intangible rural heritage from these farms, it was developed the Information Description Standard (IDS) using theoretical and methodological Information and computer sciences precepts. The IDS is compound by 13 description groups according to the scope, content and kind of heritage assets. The parameters to obtain a completed and detailed description of the heritage assets were taken from codes, standards and librarianship, archival, museological and computer science roadmaps. This research conducted a comparative study between the IDS description fields and the standard Machine Readable Cataloging (MARC 21), widely used in libraries. The methodology used a theoretical study on rural heritage and cataloging, highlighting the MARC 21 standard, followed by the comparative analysis of IDS and MARC 21. As a result, it was pointed out that the IDS needs of small interventions to enable a more complete description of the properties identified in São Paulo historic farms. In the end, it was concluded that IDS is able to perform the descriptive representation of the rural heritage satisfactorily.

This study aimed to identify the motor profile of students with interdisciplinary diagnosis of Attention Deficit Disorder with Hyperactivity (ADHD), and compare with students with good academic performance, and to verify the incidence of Developmental Coordination Disorder in this study population. A total of 46 students participated in the study, males and females, with ages ranging from 7 to 10 years and 11 months, attending from 1st to 5th year of elementary education at public schools in cities of São Paulo state. The students were divided into two groups: Group I (GI) included 23 students with Attention Deficit Disorder with Hyperactivity; Group II (GII) included 23 students with good academic performance, paired according to gender and age group with GI group. Groups experienced motor assessment (Movement Assessment Battery for Children - Second Edition (Movement ABC - 2). MABC Test consisted of eight items grouped into three sections (manual dexterity, target and precision, and balance), parents / guardians responded to DCDQ questionnaire - Brazil, which contains 25 questions about the motor behavior of the child, and the Economic Classification questionnaire. The results were statistically analyzed in order to characterize and compare the motor profile of the students, intra and intergroup. The results showed that some of the students in GI presented indicative of Developmental Coordination Disorder, whereas in GII, none of the students presented indicative of Developmental Coordination Disorder. However, it is possible to stand out an incidence of Developmental Coordination Disorder in the population with Attention Deficit Disorder with Hyperactivity in about 43%. These findings will hopefully contribute to the knowledge about students with ADHD, helping to guide actions to assist this population by teachers, health professionals, and family.

Solidary economy in Brazil appeared in the 1980s, when inflation rates and unemployment were high. It encouraged the organization of workers in cooperatives to recover the companies they worked for and that had failed, and thus keep theirjobs. The recyclable waste pickers emerged in Brazil because of the social exclusion that part of the population was exposed, around the 1950s, and began to organize themselves into cooperatives by the need of continue working after the banning of picking at landfills and dumpsites. This organization came in partnership with government, religious institutions, NGOs and universities, among other supporters. Actually, it s observed that cooperatives of recyclable waste pickers are not only composed of ex-pickers of the landfills and dumpsites, but also of other workers that are facing unemployment in current times. For the organization of economic-solidary cooperatives, it is necessary for the pickers to acquire knowledge about the nature of the project and about the progress of work. They also need the promotion of the socio-technical adaptations (STA) for the development of social technologies (TS) that that allow their development and sustainability. This process, which influences the organizational form of the enterprise, depending on how it occurs, it will need the partnership between the various agents involved in the movement of solidary economy. The consideration of various knowledges in search of a suitable scientific and technological production that benefits the people, is in keeping of the principles of the field science, technology and society (STS). Whereas that the economic and social inclusion and the labor have influence in the life of the individual and that the solidary economy with their values - solidary, individual freedom, income distribution equally, associative or cooperative organization of work and self-management-, proposes a new form of organization the work, as well as providing the economic and social inclusion, the objective of this work it to investigate the influences of labor economic-solidary relations in the family dynamics of the recyclable waste pickers. The method used is the oral history, and semi-structured interviews were conducted to collect stories about the lives of family groups of the pickers, who are members of a joint economic-solidary cooperative (COOPERVIDA) located in the city of São Carlos-SP. The interviews were transcribed and after they were validated by the interviewed people, by the transcriation process. After this validation, the transcribed data were analyzed using the technique of content analysis. Before the interviews, it was done a field work in the cooperative, with the use of the participant observation technique which was conducted in search of understanding how internal working relationships occur and how the solidary economy and cooperative working relationships traverses the environment. Among the results, we can cite the lack of AST that contribute to the organization of work processes in the cooperative; the economic and solidary principles permeate the relationships in the cooperative, but not entirely; that there is a demand for training of new cooperative to acquire knowledge about the work; families presented influences of the relations of economic-solidary work in their family dynamics, organizing their routine in a egalitarian and solidary way; and that even without being able to define what is solidary economy, the collectors and families develop behavior permeated by its principles. It s indicated the need to develop state policy, including family in programs and actions performed.

This study investigated the function of cerebellar histaminergic system on emotional memory consolidation. The cerebellar vermis of male mice were implanted with guide cannulae, and after three days of recovery, the animals were submitted to the elevated plus maze (EPM) or the inhibitory avoidance test (IA) on two consecutive days. Immediately after the first day, animals received a microinjection of histaminergic drugs into the cerebellar vermis: experiment 1, animals received microinjections of saline (SAL) or histamine (HA) (0.54, 1.36, 2.72, and 4.07 nmol/0.1 microliter); experiment 2, animals received a microinjection of SAL or the H1 antagonist chlorpheniramine (CPA, 0.016, 0.052 or 0.16 nmol/0.1 μl); experiment 3, SAL or the H2 antagonist ranitidine (RA, 0.57, 2.85 or 5.7 nmol/0.1 μl); experiment 4, SAL or HA 5 minutes after a pretreatment with 0.16 nmol CPA or SAL; and experiment 5, SAL or HA 5 minutes after a pretreatment with 2.85 nmol ranitidine (RA) or SAL. In the EPM, the decrease of open arm exploration (% entries and % time spent in the open arms) in Trial 2 relative to Trial 1 was used as a measure of learning and memory; while in the IA, latency to cross to the dark compartment was used to evaluate memory retention. Data were analyzed using ANOVA and Duncan‟s test. The results of experiment 1 showed that animals microinjected SAL and 0.54 and 1.36 nmol HA reduced percentage of open arm entries and time, while mice microinjected with HA 2.72 and 4.07 nmol did not decrease open arm exploration on trial 2; which indicates that histamine induced a dose-dependent inhibitory effect on memory consolidation. In the IA task, results showed that 1.36 nmol histamine facilitated memory consolidation, suggesting a different action of HA in a memory model that uses punishment. In the experiment 2, microinjections with CPA did not present behavioral effects in the EPM or in the IA at the doses used (0.016, 0.052 and 0.16 nmol). The results of experiment 3 showed that 5.7 nmol RA impaired memory consolidation on both protocols. The experiment 4 demonstrated that animals treated with HA did not reduce the avoidance to the open arms on retesting, and indicated that CPA did not altered behavioral parameters by itself, but the pretreatment with CPA reverted histamine-induced impairment on memory consolidation, which suggests that histamine effect on the EPM was mediated by H1 receptors. In the IA test, the results showed that the groups that received CPA+HA and SAL+HA showed a significant difference in latency on the second day of testing in relation to group SAL+SAL , while the group treated with CPA + SAL showed no difference with the control group. These results show that microinjection of histamine in the cerebellar vermis increased latency time and that pretreatment with CPA did not reverse this effect. For the fifth experiment, the results showed that animals microinjected with SAL+SAL and RA+SAL reduced the percentage of entries and time spent in open arms in the EPM while the groups treated with RA+HA and SAL+HA showed no difference between test days. These results show that RA did not alter memory consolidation and was unable to reverse the effect of histamine. In the IA, there was significant difference between SAL+SAL and SAL+HA groups, showing the facilitatory effect of histamine on memory consolidation of IA. The groups that received combined injection of RA+SAL and RA+HA showed no significant difference compared to control, which shows that the RA had no effect by itself, but when applied before histamine was able to reverse its effect. Our results suggest different histamine effects in tasks involving anxiety or fear.

Music education is seen as a well organized pedagogical procedure of literacy and awareness, giving to individuals with special needs or not the possibility to deal with their difficulties and limitations and discover their limits and skills. Despite of the growth of the researches in the music education field investigating people with special needs, the researches that focus on Williams syndrome is reduced, and most of this researches are found in international works. In Brazil, only one research was found that associates the improve to hold attention in a child with Williams Syndrome (WS) and the musicalization process. Thus, the theme of this research is to analyze the impact of music education on social skills development in individuals with WS. The general goal of this study is to verify the results of a Music Education Program for teenagers with WS. As specific goals, this work aims to: 1) elaborate, apply and evaluate a music education program for individuals with WS, related to promote social skills; 2) note and analyze if it could identify indications of better social insertion that could be assign to music education dynamics that involves auditory and rhythm perception, pulsation, visual and auditory memory, among others, as part of the musical learning process. This is a field research with a qualitative and quantitative approach. Two teenagers with WS participate in this research. The data collection instruments used were: 1) Social Skills Form, Problematic behavior and academic competence (SSRS-BR) for parents and WS people, performed at three time points (pre-, mid- and post-intervention); 2) Musical skills evaluation for teenagers with WS performed before and after the intervention; 3) Field diary, that includes records made by the researcher at the end of each intervention. The program lasted for 13 weeks for one teenager and 9 weeks for the other, with a weekly class of approximately 30 minutes each. The Music Education Program was developed in the fields that the researcher considered relevant to music learning. Data analysis was done by comparing the answers given by Social Skills Form, Problematic Behavior and Academic Competence (SSRS-BR), the Music Evaluations, the review of the filming made during interventions and field diary notes.

The present study aimed to understand the interactions between the mother and health professionals from the time of the birth of her preterm child until the first month after hospital discharge (interfere / affect) and their influence on the development of maternal care, the other aim was to identify the social network of these women that was significantly important in this process with attention to the position of health professionals. This was a qualitative study, which adopted the theoretical reference of Symbolic Interactionism and the methodological reference of Interpretive Interactionism. For data collection, an ecomap was constructed and a semistructured interview was conducted. Eight mothers who experienced the hospitalization of a child in the Neonatal Intensive Care Unit and were in the period of up to one month post-hospital discharge participated in the study. Data analysis enabled the extraction of the social support network for these women, when two situations were identified: participation and nonparticipation of the father. Further, it is in REVIEWING THE DEPENDENCE OF THE PROFESSIONAL AND HIS COMPETENCE FOR CARE that the woman manages to evolve care together with her child in an autonomous manner. The unveiled categories were: believing and obedient relationship; insecure and questioning relationship; and, reflective and emancipatory relationship. The results show that the interaction between mothers and professionals is grounded in power and this factor affects the mother's trajectory while assuming the maternal role. Thus, it is essential to provide welcoming and support in a humane manner, considering the precepts of family-centered care. We hope that this study contributes to health professionals from Neonatal Intensive Care Units with regard to the review of care provided to mothers/family.
