The Cerrado biome is located in Central Brazil Plateau occupying 2,036.448 km². Its weather is characterized by seasonality and the landscape by a vegetation mosaic. Those factors contribute for Cerrado to be known as the richest savanna in the world. It is considered one of the 20 World Hotspots, because of its high level of diversity and threat. The Cerrado is still poorly known, especially in relation to its history, origin and distribution through time, which are important factors to comprehend its recent diversity. This project aims to determine the historically stable areas within Cerrado by modelling 14 marsupial and small rodent species potential distribution for past and present scenarios, to relate the detected areas with endemism levels, to compare the identified patterns with known biogeography hypothesis of other Cerrado organism groups, and to suggest priority areas for inventory. To generate the potential distribution maps I used the digital bases available by WWF and IBGE and the SIG ARCMAP 10.1 software. The potential distribution modelling was implemented by maximum-entropy algorithm (MAXENT), using WORLDCLIM 1.4 and PALEOCLIMATE MODELING INTERCOMPARISON PROJECT (PMIP) climate variables data. The open vegetation biomes of South America were the base area for modelling, with 2.5’ layers resolution (ca. 5 km²). To statistically evaluate model performance, I used the area under the curve (AUC) of the receiver operating characteristic (ROC) plot. All models presented high AUC values. The hypothesis that during the Last Glacial Maximum (LGM) the open formations expanded and the forest ones retracted, while the open formations retracted and forests expanded during the Last Interglacial (LIG) were supported by 20 of the 28 proposed models. The historically stable areas include the Parecis , Chapada dos Guimarães, Chapada Diamantina and Central Brazil Plateaus, the western Minas Gerais and the Espinhaço range. Those areas agree to other historically stable areas and/or endemism areas already proposed for other taxa, such as birds, squamate reptiles, anuran, lepdoptera and plants. They also reflect lack of inventory data. So, the fauna of those areas should be better investigated and its material used in future phylogenetic and phylogeographic studies. Conservation should also be considered in the light of their climatic stability, resulting in the possible creation, increasing or maintaining of Conservation Units.

The model of water resource management decentralized by Basins advocates a broad participation in the decision making process , including technical and non-technical members . This research aimed to develop a tool to support this decision making process in Basins Committees (CBHs) , based on sustainability indicators ( SI) . The development of this research was intermediate steps : 1 ) identification and characterization of CBHs , especially regarding potentially problematic conditions, 2 ) to propose a set of IS to promote the monitoring of the conditions identified in the previous step , 3) the systematization Database (BD) of IS calculated based on official sources for all CBHs of the State of Sao Paulo , 4) structuring the Tool to Support Water Resources Management (FAGRH) , systematized into spreadsheets , 5) simulation application and critical analysis of FAGRH and 6) the consolidation of FAGRH. The consolidated tool proposes the selection of a CBH of the State of Sao Paulo and prioritization of potentially problematic conditions that should be covered in the proposals of this CBH . In the next step FAGRH users are advised to define what are the stages of action to be developed to address each of the priority conditions. For each step, users assign the percentage to be executed and describes one or more actions to achieve this percentage . Also in this step , the user is prompted some information about the action to be performed , such as unit cost , the amount to be performed and the correlation between the action and the proposed IS. In sequence the user is instructed to set the stage of development of each action, assigning a goal to be achieved or the financial investment to be made. With this information the user must then detail the development of proposed actions to compose an Action Plan. As final results FAGRH presents a comparison between the calculated values of IS of the BD and considering the improvements obtained with the proposed actions. The FAGRH also allows checking the percentage of budget involvement for the CBH considering FEHIDRO and FEHIDRO / Levy resources and necessary for the accomplishment of the proposed actions investments. It is noteworthy that the tool has been developed with use of spreadsheets organized in the Microsoft Office Excel file, that is a widely used software. It is concluded that the development of FAGRH collaborates with the organization and systematization of information and can be used to guide the decision making process and to implement tools such as Basin Plans and Information Systems , as well as for the preparation of reports situation.

In this work, it is a survey of data about the management methods employed by 52 selected farmers in some selected cities as Costa Marques, Seringueiras, São Francisco and São Miguel do Guaporé, in the state of Rondônia. In this research, it was noticed the importance of some organizations, such as the school households agricultural, the rural workers Union, associations and cooperatives, which permeate the activities of small producers. It was also noticed, the influence of the methodology and the language used in management education. Moreover, there’s a fact that some family members are intimately connected with property, and they hardly separate the goals of organization (farm) from personals. This fact complicates the decision they have making and requires technical school teaching management that encourages producers to build their own management tools and information based on entrepreneurship.

The spatial structure which configures the university campi, its social function and the impact generated in urban space and in the environment, present relevant issues worthy of special attention regarding new constructions as well as the rennovation and addition of the preexisting. In consequence of the national context of increasing expansion and restructuring of public campi, and the current debate on construction of a society and sustainable cities, the research´s objective seeked to verify how the guidelines and parameters of planning and sustainable projects of university campi are being approached. Therefore, the planning apparatus belonging to the Federal University of São Carlos UFSCar have been selected as the object of this study, expressed in the Institutional Development Plan and Environmental Zoning documents. For the purpose of a conceptual-theoretical foundation, a historical survey was performed for the better understanding of the institutional and spatial configuration of universities in the campi form, from their foundation to their contemporary conformation. For the verification of this work´s proposed planning, the qualitative research method used defined categories and analyses variables compiled from the conceptual-theoretical study and practical experiences regarding planning and sustainable projects of university campi. The analysis carried out in a comparative and relational manner between the categories and the documents, pointed out pertinent environmental sustainability issues such as Sustainable Urban Project, Ecology and Environment, and Education and Culture. The analysis result also identified relevant points that were not approached, for a reflection and incorporation in the planning of UFSCar.

Este artigo aborda uma parte da pesquisa que estudou o Curso de Licenciatura em Matemática da UFSCar desde sua criação, em 1975. A partir dos documentos constituídos na pesquisa, observando a organização curricular do ponto de vista das cargas horárias destinadas aos estágios, às disciplinas específicas e pedagógicas, a alteração que mais se destaca é o aumento da carga horária dos estágios e, consequentemente, da área pedagógica. O objetivo é apresentar interpretações desta ampliação tendo a teoria do campo de Bourdieu como referência. Por outra parte, o foco no primeiro curso da UFSCar nos ajuda a discutir sobre a tendência profissionalizante da universidade.

In several countries that adopt education inclusion policy, there is a device, usually provided by the legislation, called Individual Educational Plan (IEP). Its purpose is to monitor the course of the students with disabilities throughout their schooling process. In the Brazilian federal legislation, there is no policy device to ensure that these students have an IEP based on their needs. The present study raised the question of how to qualify teachers for this task. The aim was to develop, to implement and to evaluate a continuing training program for special education teachers, focusing on IEP for disability students, in a public school system. The study was conducted with 34 Special Education teachers in 2012 based on collaborative action-research and involved five steps: 1) conduction of ethical procedures; 2) diagnosis of the initial stage of assessment procedures and educational plan of the selected municipality; 3) development of the training program; 4) implementation; and 5) evaluation of the program s social validity. Interviews were conducted and 200 planning documents were analyzed, named as individual development plan (IDP), existing before the program. The interviews aimed to describe how educators planned to target public education Special Education before program. There were realized observation and recording in field s diaries, based on theoretical content and application to real cases of students, besides filming to record plan making during the course. Recourse was had collective interview and closed questionnaire to evaluate the program with the participants. The data analysis, based on content analysis was carried out to present as results: a) a description of assessment process and educational planning for target students of Special Education (TSSE) before the program; b) a description of the assessment process and collaborative planning performed during the program, with the presentation of 12 case studied; and c) analysis of appreciation measures by the participants about the training program. Results indicated that, existing IDP before the program referred only to special instruction in multifunctional resources class (MRC), with few indications for teaching in regular class,. Planning was often incomplete and/or repetitive. The participants studied various models based on the literature of the area, and built collaboratively 12 IEP documents for their students with disability. At the end, they indicated that they appreciated the training program. The results indicated that the quality of IEP affected by lack of articulation and collaboration across professionals of Education, Special Education and Health. This kind of initiative is generally dependent on the will of professionals since there is no requirement to have this practice. The lack of training and working conditions enabling multidisciplinary meetings with were factors that difficulted the implementation of the IEP. In regard to the program, this type of training requires more time for participants to review and improve its practices. The implementation of the IEP development of practice is complex, as it requires the involvement of all the people involved in the situation to think how to systematically plan the short, medium and long term throughout the school career of each TSSE. Future studies could be to increase the knowledge about how the IEP can be implemented, the impact of the adoption of this practice in the schooling process of TSSE. Legal dispositions to ensure the IEP should be adopted in our country, to improve and monitor the quality of TSSE education, both in inclusive settings as in those specialized.

The measurement of customer satisfaction has become a process of extreme importance to organizations on the competitive landscape in which they find themselves today. For this reason, there is a variety of publications of this subject. However, few are linked or cite references to quality standards. Another relevant fact is the lack of publications on the integration of industry quality standards, with the majority only addresses the integration of ISO 9001 (Quality), ISO 14001 (Environment), OHSAS 18001 (Occupational Health and Safety) and SA 8000 (Social Responsibility). Therefore, it is concluded that there is a lack of published methods that manage the information of customer satisfaction for applications in organizations that have certificates in various industry sectors quality standards. This research included a case study in a large steel company that has the characteristics to perform it and this resulted in the proposal of a method for managing customer satisfaction consisting of 14 steps, which present practices and activities that should be undertaken by the organization. To achieve this goal it was considered the standard ISO 9001 and two industry standards (ISO/ TS 16949 and NBR 15100), a matrix for integration the satisfaction requirements of the three standards, two theoretical models for measuring customer satisfaction and the context in which the organization operates.

Proper assessment of the pelvic floor muscles is essential for the correct pelvic floor dysfunctions treatment. However, currently there is not a method considered as the gold standard assessment. Therefore, this thesis aimed to evaluate the reliability of different methods to normalize pelvic floor muscles electromyography (EMG) and the determination of the correlation among vaginal palpation, vaginal squeeze pressure, EMG and ultrasonographic variables of female pelvic floor muscles. For the first aim, we evaluated 30 women aged (23,9 ±3,2 years), nulliparous, with no reports of pelvic floor dysfunction. For EMG normalization, signals were acquired during four different tasks were performed with the vaginal probe in situ: pelvic floor maximal voluntary contraction (MVC) and three daily activities with increased intra-abdominal pressure (coughing, Valsalva maneuver and abdominal contraction). The results showed that the normalization of pelvic floor muscles EMG by either peak RMS of pelvic floor MVC or mean and peak RMS of abdominal contraction has excellent reliability. To analyze the correlation between the different methods of pelvic floor evaluation we evaluated 80 women and it was carried out the digital palpation, perineometry, EMG and ultrasound. It was observed that there is a positive strong correlation between digital palpation and vaginal pressure, besides positive moderate correlation between the function and vaginal pressure contraction and RMS normalized by abdominal contraction (0.59 and 0.63, respectively), and between movement of bladder neck in relation of pubic symphysis (0.51 and 0.60, respectively). In conclusion, the results demonstrated that the normalization of pelvic floor muscles EMG by the mean and peak RMS of abdominal contraction and by the peak RMS of pelvic floor MVC should be indicated in studies involving EMG evaluation of pelvic floor muscles in young, nulliparous and free from pelvic floor dysfunction women. In addition, the moderate to weak correlation between the evaluation methods indicates that using more than one method can be positive in the assessment of pelvic floor muscles.

The Production Strategy has been the subject of several academic articles, with researches in different industries. On the other hand, Supply Strategy does not have references in a similar number and there is a gap to be filled. Furthermore, it is scarce the study of organizations in the same supply chain, and the influence between them. This study aims to describe and analyze the influence of a large elevator company's supply strategy on the production strategy of two of its suppliers, who designed 99% of its production to the customer company and the other with only 15 % of total volume. Through a case study, consisting of interviews conducted in the participating companies, it was found that the customer company´s Supply Strategy has greater influence on vendor's Production Strategy with higher production dedicated to it. This conclusion is taken by events such as the deployment of a new plant the city of the customer company, changes in engineering, plant layout, information systems and logistics of goods according to the customer needs. On the other hand, it was observed that the influence that the same company has over the other supplier is tenuous due to its low percentage of production that is destined to the customer company, and fact that the latter has a larger number of customers who must take account. Is worth nothing that the biggest influence does not necessarily translate into better performance in the short term, as in this study, the supplier with lower production percentage showed better performance compared to competing priorities, but the highest percentage, had to be more in line with customer needs following the same score in different priorities.

Recent demographic changes such as decreasing fertility rates and increasing life expectancy have favored intergenerational families. In this social context we use concepts from Social Skills Psychology, which focuses on the study of social interactions and interpersonal relationships. Social Skills (SS) are social behaviors that enable Social Compentence. There are different classes of SS: Assertiveness, Conversation and social resourcefulness, Emotional expressiveness, Empathy, Self-control. Interpersonal relationships have also been studied under the theoretical model of Intergenerational Solidarity (IS), which includes six dimensions: (1) Affectual (feelings and evaluations), (2) Associative (frequency and type of contact), (3) Consensual (agreement in opinions and values), (4) Functional (support), (5) Normative (expectations about obligations and norms) and (6) Structural (opportunity for interaction, due to geographical proximity) , and usually studied in association with conflict. Given that these two theoretical fields involve the interpersonal context of human development, it is possible to assume an interface between them. More specifically, social skills may be an antecedent condition favoring intergenerational solidarity. Thus, the aim of this thesis was to evaluate a possible interface between SS and IS, as well as relationship quality (RQ) among older parents and their adult children. The sample was composed of 69 parent-children dyads, ages 60 to 85 years for parents and between 25 to 50 years for the adult children. The dyads were separated according to the gender of the participants, yielding four types of dyads: Mothers and daughters (n = 17), Mothers and sons (n = 18), Fathers and daughters (n = 17), Fathers and sons (n = 18). Instruments were: IHSI - Del - Prette, IHS-Del-Prette, Scale of Intergenerational Solidarity, WHOQOL-OLD and Criterion Brazil. Descriptive and inferential analyses were performed. Initially, an analysis was performed by judges: experts evaluated the possible semantic relations between items of the IS and SS. Subsequently, correlational analyses were performed for SS, IS, sociodemographic variables and Relationship Quality. In these analyses we found evidence of association among these variables. From this evidence, models were developed through structural equation models for dyadic analysis using the Actor -Partner Interdependence Model with two predictors (at a significance level of p < 0.05, with effect size - D Cohen equal to 0.15 and the statistical power of 0.80). SS classes were found to be predictors of dimensions of IS and Conflict in intra and intergenerational analyses. We discuss the implications of these findings for research, evaluation, intervention, training of health professionals, public policies and social programs.

The diversification of farm and agroforestry systems brings many ecosystemical services to the environment, the attraction of natural enemies and the decrease of herbivorous insects. A particular group of insects in agroecosystems are the ants, organisms that occur in all land Agroecosystems as predators and as plagues. The aim of this experiment was to analyze the occurrence of different guilds of ants in different forest restoration strategies in agroecosysten. For this purpose were collected monthly from February to July of 2013 ants on a farm in the city of Sete Barras in the Ribeira Valley, in different patterns of forest environments and agroforestry. It was noted that the predatory ants occur more frequently in areas with advanced vegetation successional stage, and that the leaf cutting ants occur more frequently in environments of vegetation in early stages of succession. This information can be use as an indicator of ecosystemical services by the biodiversity inside the agricultural properties that can be noted by the farmers himself suggesting that ants can be used as biological indicators in Agroecosystems transitions.

Sugarcane plantations are increasing in Brazil motivated by the demand of the sugar industry and the energetic sector. Sugarcane monocultures simplify the landscape and disconnect natural ecosystems. The inclusion of native trees in the canebrake, changing the matrices into an alley cropping system, is a new proposal that consider the environment beyond production. In order to assess the environmental effects in agroforestry was raised sugarcane productivity and development of trees in three crops (2009/10, 2010/11 and 2011/12), as well as the timber volume and carbon sequestration produced by the system at the end of the year 2012 and a bird survey during 2011 and 2012 in an experimental area of 1,957 hectares. Was found orderly development of tree species. Schizolobium parahyba present a significant mortality, but had the largest wood production thus coming to the same conclusion in relation to carbon sequestration, which are 3 times those of the Handroanthus spp. and 2 times the Cedrela fissilis. There was no change in the sugarcane productivity related to the distance line planting was the alley, with only a drop productivity in the range of 58 m cultivation. Birds are important bioindicators; trees contributed to the increased diversity of birds, being Schizolobium parahyba the arboreal species of most relevant importance. The spacing between alleys with the greatest diversity of birds was to 29 m. It is concluded that it is technically possible deployment agroecosystem proposed, without agronomic production damage of cane sugar; the 2 smaller bands cultivation (29 m and 43.5 m) are the most suitable; among tree species Schizolobium parahyba was the one with the best results in the short term, since the issue of mortality could be remedied with proper management or replanting.

Disasters are socio-environmental phenomena, resulting from the interaction between a natural phenomenon in this case heavy rainfall and a given social organization, and culminating in a tragic event with both material and immaterial losses. In the social sciences, disasters are not considered to be natural, but rather a product of social, historical and territorially circumscribed processes (VALENCIO, 2009). They reveal the spatial superposition of social and environmental problems, whose state of crisis causes the emergence of a biopolitics of disaster, in order to guide a way to govern in the face of the event and, thus, deal with the populace as a political, scientific and biological problem and a problem of power (FOUCAULT, 1999). Thus, a set of techniques, power mechanisms and security devices are employed with the aim of trying to manage the problems that arise in the crisis setting. Classificatory security techniques are produced, imbued with knowledgepower discourse, in order to create an administrable reality, thus aiming to frame the complexity of the social problems revealed in the scene as something propitious for technical management, emphasizing the aspects of this reality which could be solvable. Exceptional security and governance techniques to manage calamities are created, called Situation of Emergency (S. E.) and State of Public Calamity (S. P. C.), coups that permit the creation of fissures in the legal order, causing the forces of the State to grow (FOUCAULT, 2008b). In Brazil, studies by Valencio (2012) showed that there were 10,195 declarations of S. E. or S. P. C. in the period from 2003-2009 (average of 1,456.42 declarations per year), which reveals that this form of governance became the rule and not the exception. I defend the thesis that these declarations of Situation of Emergency and State of Public Calamity are part of a biopolitics of disaster, used as techniques to increase the power of the State that, in the first moment of the emergency, saves lives, but that, after the impact, leaves to die, because the social demands of reconstruction and recovery are disconnected. The logic of power, the discourses and habits of the subjects involved in the postimpact process, that is, recovery and reconstruction in the face of disasters related with heavy rains in Brazil, are described. The disaster in São Luiz do Paraitinga, SP, a city that was flooded in January 2010, is used as a case study. A review of the state-of-the-art, documentary research and qualitative field research are adopted as methodological procedures. The temporal selection includes the period between January 2010 and June 2013, with the understanding that the process of social recovery is long term and extends beyond the period of this study. The results reveal that with the passing of time, especially with the end of the 180 day validity of the State of Public Emergency, the logic of saving lives become subtly diluted and a naturalizable logic of leaving to die gradually enters the scene, in the face of which the citizens of São Luis do Paraitinga, based on their socio-cultural repertory, seek strategies to create opposition. Discursively, the day of the disaster, a disaster that occurred is spoken of, but many of the practices reveal its continued existence.

Dengue is a pathology caused by a virus transmitted by the Aedes aegypti mosquito and is considered one of the most serious public health problems in America. School is a privileged environment for efficient activities aimed at the same, but to do so, it needs to be pleasurable and attractive to students. The development of computer-supported software and/or educational activities directly interferes with the learning outcome and can be used in the classroom in a playful and fun way, providing intrinsic motivation in this sense. Thus, this work aimed to evaluate games on the theme “dengue” available on the internet and also to design an interactive game on the same subject, as a support for teachers and students in basic education in teaching Science. The game “Everyone against Dengue” was developed using the Microsoft PowerPoint® authoring tool. During the conception and design of the game, criteria such as target audience, content to be covered, duration and number of phases, and level of difficulty, among others, were considered. Subsequently, a testing phase was carried out to evaluate the technical functionality and suitability of the content. Through the application of a questionnaire, using the Likert scale, it was found that the majority of participating volunteers were in favor of the game, configuring its viability and acceptance. Therefore, it is expected that this game will serve as a tool to support basic education teachers in teaching about dengue and as an instrument in the training of students, informing them about the risks and prevention of this disease, as well as making them agents that modify this reality. in their communities.

The presence of digital technologies in everyday life of a significant part of human beings occurs increasingly intense way. At the same time, in the classroom space, the repression of feelings consolidates intensely. In this context, Youtube seems to be the scene of regressive catharsis by students. Aiming to understand how to (re)configure the relationships between teachers and students on new spaces of expression, this research investigates eight videos, posted on YouTube by students, showing the tension between the actors of the educational process, based on Critical Theory and Psychoanalysis. Thus, it presents one of the greatest challenges of education today: a new relationship between students and teachers as from the dialogue about and through digital technologies.

In recent years, researchers from industry and universities have focused their interests in polymer nanocomposites, especially in multifunctional composites. The composites made from nano expanded graphite ( nGE ) can provide to the polymer matrix an innovative balance of structural, electrical and thermal conductivity, electromagnetic shielding and improved barrier and wear resistance properties. The increasing demand of using biodegradable polymers, such as poly (lactic acid ) (PLA ) and its blends with poly ( butylene succinate) (PBS), in packages of short lifespan with low resistivity requirements, motivated this work. Nanocomposites of nGE with PLA and PLA / PBS blends were evaluated on the effects of conductive nanofiller content and processing methods in their rheological, mechanical, and electrical properties, in order to correlate and possibly control the formation of the percolation network. The nanographite had a major mechanical reinforcement effect in of the composite with PLA / PBS, increasing all tensile properties. Through microstructural analysis, it was was observed the selective localization of graphite particles in PLA, forming a percolated co-continuous phase with PBS phase. This phenomenon was identified as double percolation, result of the preferential nGE gelation in PLA by the processes of coalescence of PBS and possible crystallization of polymers in the blend. The PLA composites remained resistive, since the nGE particles homogeneous dispersion was maintained. The lowest resistivities were found in the samples of the blend processed by compression moulding, more favorable process for the formation of the electrical percolation network through the mechanisms mentioned above. The coalescence of PBS phase proved to be determinant for the electrical percolation.

The object of this research is the formation of the Brazilian sign language teacher (Libras), in particular, pedagogically. The study about the Libras teaching and teachers formation is a new subject. Herein, I discuss some international experiences focused on the formation of the sign language teacher. A link is created between the formation conditions and the public policies for the formation of teachers, describing the syllabus for the Brazilian course, once the subjects for this research are submitted thereto. I compiled elements for the formation of teachers based on Bakhtinian studies for a methodology for teaching/studying languages. This work is structured as a field research carried out with teachers graduated with a Teaching Certification in Libras under the distance learning system coordinated by the Federal University of Santa Catarina. A Libras "back-talk focus group" was established, which was constituted by five deaf teachers, and the researcher acting as the group s mediator. The meetings were scheduled monthly, for one year (ten meetings with duration of two and half hours each). It was made a video recording and translation/transcription of these meetings. Based on the group enunciations, events discussing pedagogic practices and conceptions were selected. Based on the dialectical method, principles raised by Vygotsky (1998) were used, wherein the processes are analyzed and not only the object/product alone, articulating the microgenetic level of social interactions with the study of the dialogical-discursive behavior. Thus, elements from specific events were associated to macrosocial conditions. On a theoretical-methodological reference, the researcher sought support in historical-cultural approach theories, in particular, in the ideas published by Vygotsky and Bakhtin, which find its foundations on the enunciation and mediation, highlighting the importance of the role of our life s history, of our language and of our experiences in the constructions of our conscience. The concepts of meaning and sense were applied; the concept of dialogic; proper wording and the word of others; enunciation, ideology and enunciation, associating these concepts in order to understand the formation of teachers and the Libras teaching processes. The object hereof is limited to understand the history of formation of Libras teachers in Brazil, and the nature of the knowledge (scientific/technical) destined thereto at the time of the initial formation. The hypothesis was that, even with an initial formation, teachers presented theoretical-practical difficulties in their teaching performance. Upon the analysis of aspects of the initial formation and the enunciations of the group of teachers, it was interpreted the manner in which they signify and resignify their work, and how they apply their methodological knowledge to teach this language. Therefore, the analysis was carried out under three categories: 1) meaning and sense of the teaching work; 2) theory and practice in the teaching-learning process of the language; 3) political ideology and conscience. A thesis was established in which the formation of the Libras teachers must take into consideration the pedagogic practice as a political and didactic action within discursive contexts, providing the future teachers the understanding that the language is not an abstraction described by linguistics (solid), but that it is a part of the enunciation process. For this reason, the language is frequently mobilized by the active understanding, the teacher, therefore, being responsible for creating and conducting interactions that make Libras learners to take over manners to signify the world in this sign-visual language. This knowledge may favor the formation of future Libras teachers.

This work presents a study and development of long glass fiber PVC pellet concentrate (LF-PVC) manufactured by extrusion similar wire coating technique to reinforce pelletized rigid PVC compounds to produce injection molding LF-PVC composites. The incorporation of LF-PVC in rigid PVC compound exhibited mechanical benefits mainly in tensile modulus, flexural modulus and notched impact strength. Injection molding LF-PVC composites with 20 wt% of fiberglass presented tensile and flexural modulus 90% higher than unreinforced rigid PVC; Izod and Charpy notched impact strength 13% and 40% higher than unreinforced rigid PVC, respectively. The reinforcement of rigid PVC with LF-PVC presented slight damage in heat distortion and Vicat temperatures. 20wt% fiberglass PVC composites presented around 10% lower than unreinforced rigid PVC because LF-PVC reinforcement presented little quantity of plasticizers and majority of low molecular weight PVC resin. The innovative technique developed by Grizzo in a preliminary work [1; 2] to incorporate long glass fiber in rigid PVC compound was optimized because the LF-PVC pellets produced presented lower quantity of plasticizer, adequate fiberglass roving with suitable coupling agent (sizing) for PVC and a fiberglass roving tex (g/km) with excellent cost. In summary the reinforcement of injection molding rigid PVC compound with LF-PVC compounds produced unsatisfactory mechanical performance of LF-PVC composites, although that allowed them to compete to long glass fiber polypropylene and polyamide composites in injection molding technical parts under room temperature. Also LF-PVC composites allowed improve usual PVC applications such as connections to reduce thickness or rise dimensional, for example diameter and length, which was not possible before. The last, there are potential applications for LF-PVC composites to be used in special pressurized connections to replace internal metallic reinforcement, and in faucets and other bathroom devices for metal replacement.

Different electrochemical techniques were used to characterize the boron-doped diamond (BDD) electrode and to determine estrone. After parameters optimization, the detection limits obtained using differential pulse voltammetry (0.27 μmol L 1) and square-wave voltammetry (0.096 μmol L 1) with a cathodically pretreated BDD electrode were comparable to values reported in the literature. An even smaller value was obtained when amperometric detection was used with a flow injection system FIA-EC (0.050 μmol L 1), because there is a reduction of capacitive current interferences when a fixed potential is applied, as the continuous flow rate (surface cleaning and mass transport effect). In all cases, the BDD electrode presented a stable response (inter- and intra-day repeatabilities) and different matrices did not have significant influence on the detection of estrone. Consequently, the investigated techniques are promising for this purpose, with excellent accuracy and precision. In the electrochemical degradation of estrone studies in a flow reactor a rapid decay of estrone concentration was attained, due to the high oxidation power of the BDD electrode. This decay is dependent on the studied parameters (current density, flow rate, and pH); best results were attained at pH 3. Intermediate products formed during electrolyses of estrone at different pH (3, 7, and 10) were investigated by LC-MS/MS; thus, inedited (partial) degradation pathways were proposed, aiming at understanding the influence of pH on the generation of intermediates. Finally, electrochemical degradation of estrone at pH 7 using the BDD electrode was compared with the one attained with a β‒PbO2 electrode, also with an inedited mechanistic study.
