The neotropical freshwater fish fauna is the most diverse in the world, with more than 4.000 descrbed spcecies. In Brazil, about 2.500 species of freshwater fishes are considered valid, and the most formallyand a small portion under description, however, it is believed that this number can be significantly higher. Auchenipteridae, which is restricted to the Neotropical region, comprise 20 genus and about 90 species, of which 74 have been recorded for the Brazilian territory. Genetic studies, both chromosomic or moleculars, in Auchenipteridae, are few since the great diversity of species in this family and their wide geographic distribution. Thus, this thesis was developed with the goal of advance the knowledge in this family, specifically with regard to chromosomal studies classical and moleculars in the genus Ageneiosus, Parauchenipterus, Glanidium, Tatia and Trachelyopterus, and in the application of analysis of the DNA mitochondrial sequences to help in taxonomic problem involving the genus Parauchenipterus and Trachelyopterus. Ageneiosus is the genus most widely distributed among river basins of South America. Although chromosomal studies in the family are still few, this genus is the most studied in number of species, ranging from 54 to 56, differing from the rest of the family which present 58. Chromosomal analysis was performed in A. inermis of Araguaia river basin. Ageneiosus presents a slightly different genomic organization compared to the other species of Auchenipteridae. Evidences indicate that a chromosomal fusion that originated the first metacentric pair of A. inermis, can be a rearrangement basal for the genus. Regarding the B chromosomes, in this study, was described the second case of B chromosomes in Auchenipteridae (Trachelyopterus sp.), and it has been hypothesized that the B chromosomes this species may have a common origin in relation to the B chromosomes of P. galeatus. As expected, the results confirmed the great phylogenetic proximity between the genus Parauchenipterus and Trachelyopterus, moreover, indicated that the B chromosomes of the two species may present a common origin, prior to the diversification these genus. With regard to Tatia, this genus belongs to the subfamily Centromochlinae and has 13 valid species. Of these, T. viii jaracatia and T. neivai represent the only two species of the Paraná-Paraguay drainages. Chromosomal analysis was performed these two species, and thus, the first chromosomal data were generated for the genus. The two species of Tatia showed large chromosomal similarity, however, when compared with the others of Auchenipteridae, was possible to identify some differences in the karyotype formula, in the pattern of heterochromatin and in the distribution of 5S rDNA, which appear to be intrinsic of Tatia. Regarding to Glanidium ribeiroi, this species was collected at the Iguazu river, being that its fauna is characterized by high endemism, which is due to two factors: its rugged topography and their old insulation provided by formation of Iguazu falls. Chromosomal analysis was performed in a population of G. ribeiroi collected in a region in the final stretch of this basin, and the results revealed populational differences when compared with previous studies in others populations of the Iguazu river, which must be related to the rugged topography of this basin. In this thesis, was also presented an adaptation of the banding C technique, with respect to the use of a fluorescent dye (propidium iodide), rather than of non-fluorescent dye (Giemsa). This adaptation produces greater contrast of the heterochromatin bands in metaphase chromosomes and can be especially valuable when the organisms studied possess heterochromatin that is pale and difficult to visualize. Finally, the data obtained concerning the genus Parauchenipterus and Trachelyopterus, both by chromosome analysis as by analysis of two mitochondrial genes, will be used in the discussion of a paper still in preparation, that involves the validation or not of Parauchenipterus, genus that has been subject of debate in the taxonomic .

During the last years we have witnessed a significant growing in the amount of data processed in a daily basis by companies, universities, and other institutions. Many use cases report processing of data volumes of petabytes in thousands of cores by a single application. MapReduce is a programming model, and a framework for the execution of applications which manipulate large data volumes in machines composed of thousands of processors/cores. Currently, Hadoop is the most widely adopted free implementation of MapReduce. Although there are reports in the literature about the use of MapReduce applications on platforms with more than one hundred cores, the scalability is not stressed and much remain to be studied in this field. One of the main challenges in the scalability study of MapReduce applications is the large number of configuration parameters of Hadoop. There are reports in the literature that mention more than 190 configuration parameters, 25 of which are known to impact the application performance in a significant way. In this work we study the scalability of MapReduce applications running on Hadoop. Due to the limited number of processors/cores available, we adopted a combined approach involving both experimentation and simulation. The experimentation has been carried out in a local cluster of 32 nodes, and for the simulation we have used MRSG (MapReduce Over SimGrid). In a first set of experiments, we identify the most impacting parameters in the performance and scalability of the applications. Then, we present a method for calibrating the simulator. With the calibrated simulator, we evaluated the scalability of one well-optimized application on larger clusters, with up to 10 thousands of nodes.

The researcher is responsible as the main objective of expanding knowledge that in order to actualize it as a contribution to science must be recognized and understood by other scientists. Thus, the possibility of shared work and adds value to the integrated object searched. Given this, reflect on Special Education and Speech interface becomes important compared to the current context of joint work and collaboration that pervades the scientific world. Thus, this research aimed to identify the theoretical frameworks used by the authors of dissertations and theses in the Graduate Program in Special Education, Federal University of São Carlos (PPGEs/UFSCar), interface and Special Education Speech during the years 1981 to 2009, and to analyze the scientific collaboration networks formed in the publication of books, book chapters and articles that characterize the interface. The research proposal was kind of investigative documentary with an exploratory-descriptive way. We used two different methods: a bibliometric analysis and social network analysis. In bibliometric analysis, data were extracted from 96 studies components of the interface screen (78 dissertations and theses 18). Moreover, the analysis of scientific collaboration networks, data were extracted from the Lattes platform of Lattes from 73 authors that have characterized the interface, selection was focused on three formats: book publishing, book chapters and articles. As a preliminary result we can observe that the networks of collaboration showed distinct characteristics in the three formats of publications, especially in the form of books that the networks formed by the authors found themselves disconnected because the formats of book chapters and articles, there collaboration to occur among different authors with different trait. However, the themes that developed were the most frequently targeted for the hearing impaired, wrapped in greater inter-institutional relations between university degree UFSCar, USP and UEL. It is hoped that the analysis of the collaborative networks can contribute as facilitator and promoter of research, so that the interface is strengthened and the relationship between the two sciences pervade other subjects, also important for the growth of both areas.

The aquatic macroinvertebrates are widely used in ecological studies and recently applied for biomonitoring. The knowledge about composition and distribution patterns are essential to elaborate environmental biomonitoring programs. The Cerrado vegetation, considered hotspot of biodiversity, is one of the most threatened savanna in the world and due to this importance its biodiversity and natural resources needs their own methodology for monitoring. In view of the above this thesis was divided in two studies: 1) Study about the variation in faunal composition of the metacommunity and the importance of local variables and spatial variables. 2) Development of a regional multimetric index using metrics from the macroinvertebrates community. Both studies used the database of 21 streams from the central region of São Paulo State, being 14 impacted streams (seven of sugarcane monocultures and seven of pasture) and seven reference streams, inserted in conserved Cerrado areas. The results of the first paper showed a metacommunity influenced by local factors and little variation was explained by spatial factors. These results fits the studied metacommunity in the species sorting model, considered the ideal for bioindicator groups. In the second paper the filters tested the metrics for range, sensibility to anthropic impact, redundancy between metrics, correlation to natural variability of streams and simplicity. The following metrics passed all filters: of EPT richness to family level, Shannon s Diversity Index to family, percentage of Trichoptera, EPT/Chironomidae and Biological Monitoring Working Party adapted index. The 5 developed multimetric index use metrics of low taxonomic resolution and good response to environmental impact, showing a potential for application in biomonitoring programs in the studied region.

The sugarcane bagasse is a lignocellulosic material that can be converted into ethanol by action of cellulases and xylanases. These enzymes act synergistically to convert cellulose and hemicellulose into glucose. In order to obtain an enzyme that can perform dual function, a chimeric enzyme cellulase-xylanase denominated ThEg3Xyn3, was constructed by gene fusion in our laboratory. The fusion was performed by binding the C-terminus of an endoglucanase from Trichoderma harzianum to the N-terminus of a xylanase of the same fungus, separated by a linker. The chimeric enzyme was recombinantly produced in Pichia pastoris and purified for kinetic and biochemical characterization. The chimera demonstrated activity of both enzymes with maximum activity at 38 °C and pH 6.0, under these conditions, cellulolytic and xylanolytic activity was greater than of the parental enzymes. The results demonstrate that the chimeric enzyme can be efficient in hydrolysis of the biomass and satisfactory for the production of ethanol by the process of simultaneous saccharification and fermentation.

In order to minimize the side effects of chemotherapy concurrently with the enhancement of its therapeutic action is to use it on devices that enable a controlled drug release, by vectors, such as polymeric microspheres, which act as a drug carrier, modifying its distribution pattern in the organism. Paclitaxel ((Taxol®) is a drug used primarily in the treatment of ovarian, breast, lung and bladder cancer. Due to its antimitotic and antiproliferative action, there is a potential interest in cancer therapy. However, the success of this clinical application is limited to low solubility in water and toxic action. The objective of this study was to obtain and characterize physic-chemically the bioresorbable and biocompatible copolymer poly (L-co-D, L lactic acid) (PLDLA) microspheres encapsulating the paclitaxel chemotherapy. The simple emulsion technique allowed to obtain spherical microspheres, verified by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The average size of the microspheres PLDA pure and containing paclitaxel were, respectively, 10.3 μm ± 1.7 and 12.7 μm ± 1.3, obtained by the technique of laser light scattering (LLS). Moreover the essay of differential scanning calorimetry (DSC) suggests that the drug paclitaxel is homogeneously dispersed in the microspheres PLDLA. The encapsulation efficiency of the microspheres PLDLA paclitaxel was 98.0% ± 0.3, obtained by high performance liquid chromatography (HPLC). The in vitro release study performed on HPLC showed initial burst release followed by a slower release, which characterizes large diameter distribution systems. PLDLA microspheres released 90% ± 4.0 of the drug paclitaxel up to 30th day of study while the degradation process occurred. Thus, the microspheres obtained PLDLA devices are promising as carriers of paclitaxel, with potential for future applications in drug delivery systems.

The challenge of the inclusion of people with disabilities in different segments of social relations is not new and it is undoubtedly a complex process. In formal education deaf students are also offered an interpretation service performed by a Translator/ Interpreter of Brazilian Sign Language, in this dissertation referred to as educational interpreter (EI). Thus, under the assumptions of enunciative-discursive perspective, the objective of this study is to identify (1) strategies adopted in the interpretation from Portuguese to Brazilian Sign Language in the context of a Lato sensu graduate course and (2) influences experienced by an interpreter in this activity. The methodology adopted was participant ethnographic research, since it enables forms of interaction between the researcher and the subjects that no other technique does. In this study Libras interpreters (the author and other professional researcher invited) participated, in addition, an adult deaf student, a professor and other hearing students took part. Data collection was conducted through video recording of the interpretation of the classes in the university s classroom. The classes analyzed (part of a specialization course on "Sustainability - in the context of construction / architecture) had as subject "Energy Efficiency." The activity of educational interpreting, especially in higher education is a difficult task since it involves not only technical knowledge, but also conceptual, social, academic and linguistic knowledge related to the course theme. At that point, we realized that active-dialogical understanding and interaction weave the IE s and the student s knowledge, who are active subjects in the productive chain of meaning, with the clear goal of promoting student's learning.

Communication is an important resource for child development, because through it the children acquire communication skills and relate to people. Children with severe communication disorders require a rehabilitation program directed to the orientation and manipulation of the user and the family. In this context, it is essential the participation of the person responsible for the child within the family context in the process of choose, development and adaptation of the resource, since parents know better wishes, the center of interest and the routine of their children. The partnership between parents and health professionals has the purpose to make the family an active and cooperative member during this process. The objective of this study was to develop, to implement and to evaluate an Individualized Program of Augmentative and Alternative Communication for parents of children with Cerebral Palsy. The research took place in the Family and School Unity at Federal University of São Carlos, located in São Paulo State, Brazil. The study included 3 children with cerebral palsy and their mothers. In this study was it was used ten instruments; 5 of them were constructed specifically for this study: two protocols about Characterization of the participants; one Interview outline with the objective to identify communication skills already used by the child through the report of the mothers; Protocol for analyze the baseline and intervention with objective to describe in details the video of the baseline and intervention, an outline to analyze mothers perceptions about program effectiveness, Motor Function Measure Classification System with the objective to classify children motor function movements in sitting and walking, Brazil Criterion Questionnaire was used to evaluate and categorize the possession of consumer durables and education level of household head and the Protocol for the Selection of the figures in order to select items from children interest reported by mothers, which are related to the theme of self-care, productivity and leisure. In order to verify the effects of the intervention it used Multiple Baseline Design cross subjects including two phases: baseline and intervention. The results were described in three studies. The study I reveals data on the communication skills of children before and after the intervention. The data showed existing communicative skills in children, and a low input repertoire and acquire new skills through the implementation of alternative communication. The study II data revealed Intervention Process, mothers and children before the intervention process lacked a repertoire of meaningful input before the issue of alternative communication. With the intervention, the repertoire of the mothers was significant and there was an excellent performance in using the same communication capabilities as well as an alternative expressive performance by children in communicating their desires through the figures. Study III showed the mothers' perceptions about the relevance of the use of communication resources to get your kids to express themselves in situations of everyday life. Thus, the premise that the deployment of communications capabilities supplementary and/ or alternative through a partnership with mothers of children with cerebral palsy do not favor the expansion of verbal interaction and acquire new communication skills was confirmed. Considering the results presented above, the above research hypothesis was tested and confirmed. Thus, it is expected that future studies can be developed from the perspective of socializing program in clinical and educational context of daily life of children with cerebral palsy nonverbal.

The aim here is the fabrication and characterization of nanostructured thin films of different materials inside microchannels to assist the integration process of electronic tongue in lab-on-a-chip devices. The ultrathin films were deposited inside the microchannels using dynamic layer-by-layer technique through copper (II) tetrasulphonated phthalocyanine (CuTsPc) and poly(allylamine hydrochloride) (PAH) bilayers, and also bilayers of poly(3,4-ethylenedioxythiophene) poly(syterenesulfonate) (PEDOT:PSS) and PAH. It was verified the best parameters involved in the nanostructuration of the materials throughout flow and time variations of the deposition of the electrolytes inside the microchannel. Moreover, the growth of the LbL films inside the microchannel was followed by UV-vis and impedance spectroscopy measurements. Through electrical impedance spectroscopy technique was observable that deposition of thin films PAH/CuTsPc was successful using a time of 8 min with a flow of 1500 μL/h, while to films of PAH/PEDOT:PSS optimal time was of 15 min with a static deposition. Raman analyses were used to ascertain of the presence and uniformity of film inside the microchannels. All films of PAH/CuTsPc show good Raman signal, especially those was deposited at 8 min with flow of 500 μL/h. Just films of PAH/PEDOT:PSS deposited in a time great 10 min showed Raman signal; the films deposited at a time of 15 min and flow of 1500 μL/h showed good Raman signal and films more homogeneous. It is worth mentioning that the fabrication of the microchannels and interdigitated electrodes was made in collaboration with Laboratório de Microfabricação do Centro Nacional de Pesquisa em Energia e Materiais (CNPEM) through a specific project in this research line (LMF-13070).

This paper describes the study of variation in the chemical profile of citrus after inoculation of the fungus Alternaria alternata, who causes the disease known as alternaria brown spot (ABS), which is one of the most serious diseases in orchards of tangerines, causing major damage to the Brazilian citrus. For this, A. alternate was inoculated in sweet orange (resistant) and Murcott tangor (susceptible) to evaluated the modification of chemical constituents through study using HPLC-DAD coupled with chemometric tools and analysis of constituents volatile of these varieties. The histopathological study of the interaction between this microorganism and citrus varieties studied was done using SEM-Environmental and was observed the penetration of the fungus into the tissue of citrus susceptible. The phytochemical study of citrus was done with the objective of obtaining substances for testing inhibition of mycelial growth and appressoria formation of A. alternata, which resulted in the isolation of 17 secondary metabolites. The chemometric analyses of the variation of the chemical profile of citrus studied detected a possible local response in leaves of Murcott Tangor. Then, to check this result was done in an experiment in 1H NMR 600 MHz and was observed a accumulation of flavonoid apigenin 7-O-rutinoside in leaves of Murcott tangor with symptoms of ABS, when compared to control of this leaves. This result stimulated the investigation of the distribution of this substance in leaves intact Murcott tangor control and leaves with symptoms of ABS, which was performed using MALDI-IMS, indicating an accumulation of this substance in symptomatic leaves of Murcott tangor.

This research presents the topic of Natural Disasters and how it has been treated in Brazil and around the world, especially regarding the preparation stage for this confrontation and response, where there are possibilities for logistics support to better serve society affected for such an event. There is much to logistics is being developed in various sectors, from military to business in which they are applied his concepts and techniques to ensure the best balance between the costs of industrial operations, commercial and transportation and customer satisfaction. Currently, several studies have been developed to suit the limited resources to care for victims of disasters being named Humanitarian Logistics. With regard to disaster response operations, many researchers point out that one of the biggest difficulties for logistics activities is the identification of the necessary information, such as demand and its features, which makes the response time inadequate to meet the needs of affected population. This research proposes a starting point for the solution of this issue through the preparation, organization and provision of appropriate information. We performed a literature review about the topic of Natural Disasters and their particularities imply that their phases of pre-impact, impact and post impact, as well as the typical approach front of them related to the various actors responsible. Were exposed to the key concepts and techniques of logistics, humanitarian logistics and information processing. Various data were collected in the literature in order to get a clearer understanding of logistics activities and information that would be useful to decrease the response time, some of the cases studied. It reached a preliminary classification of the main information needs that impact on demand as well as in preparing to meet the same that led to the adaptation of an information flow that enables the provision of information at the initiation stage of the response to policy decision. The integration and provision of appropriate information to administrators Disaster directs better preparation of necessary logistics to respond to natural disasters by reducing the time for the initial collection of information, making the triggering of the response faster, thus improving the quality of care victims.

In recent years, international trade has intensified and liberalized, so that decreases in border costs have become increasingly relevant. Much of these costs are associated with the excessive number of documents required to export or import, the bad infrastructure of ports and airports, among others. It is in this sense that stands out the importance of trade facilitation, principally regarding logistical factors. The trade facilitation began to be discussed at the WTO in 1996, but only in 2004 began the negotiations about it. Several papers have been written for several countries in order to assess the impact of trade facilitation on trade flows. However, studies for the brazilian case are still few, especially those that take into account logistical variables. This study aimed to identify the effects of trade facilitation, especially concerning logistics, upon the pattern of trade that includes Brazil and its major trading partners witch belong to the most important economic blocs. The data extends from 2008 to 2011 and takes into account variables on the quality of transport infrastructure and customs procedure. Gravity models considering Brazil and other 47 counties, witch were responsible for about 78% of brazilian exports in 2011, were estimated. The results evidenced the largest impact of custom variables on trade flows between countries. When considering separate models for blocs of developed and developing countries, the results showed the importance of improvements in terms of documentation, time and cost for blocs of developing countries, as well as improvement regarding the time for blocs of developed countries. With regard to transport infrastructure, good quality of rail was important for both groups. Finally, it was concluded that, for blocs of developing countries, there is a dependency on reforms in trade partners, while in blocs of developed countries the reforms made by the countries themselves have greater impact on trade flows.

It is believed that the production function must support the competitive strategy, offering an important contribution to the competitiveness of an organization. The production strategy, whose content is determined by competitive priorities and the structural and infrastructural decision areas, plays a fundamental role in this process and should be aligned with competitive strategy. Moreover, recognition of the importance of innovation and technology has intensified to the point of becoming one of the most representative items in a company. Thus, based on the importance of manufacturing strategy and innovation in the organizational context, this study aimed to analyze the influence exercised by competitive priorities in the occurrence of innovations in small companies of metal mechanic sector in Sorocaba/SP. Since small businesses have certain specific characteristics, the study aimed to analyze how these specificities influence the practice of competitive priorities and the occurrence of innovation. To collect and analyze the data, it was used a qualitative approach and method of multicase study. Among the main results, it was found that the quality, flexibility, delivery and cost proved, in that order of importance, as generators of innovation practices in the surveyed companies. The quality and flexibility were closely related to product and process technological innovations. In the case of non-technological innovations, quality influenced the organizational and marketing innovations. Regarding the characteristics of small businesses, as facilitating factors for the practice of competitive priorities and the adoption of innovations, it was observed the specificities centered on the figure of the owner, on internal organization and the influence of the environment. As factors that worked as barriers are related to the specificities centered on the influence of the environment, mainly, and the specific focus on internal organizational of the company.

This study is the result of a field research theme of "social dynamics of recognition and the establishment of the university teacher habitus", made from semi-structured interviews that focused on family and school career / academic. The selected group of teachers was considered a department of excellence in science, from a public university in the state of São Paulo. Had we assume the formation of a habitus that is peculiar to these professionals and that related to the social construction of a professional identity and associated personnel rules and practices of academic-scientific. The objective was to analyze the existence of the relationship between the dynamics of recognition in the scientific field and the establishment of lasting provisions peculiar to their agents, which have shown to be associated with an ideal of performativity and success. In this perspective, from the use of qualitative research method and emphasis on discourse analysis as relevant social practice, we analyzed the relationships between values, choices and needs that guide individuals' sense of investment in scientific field; investment in their rules and their "game" peculiar.

As the number of elderly increases due to the aging population, the prevalence of chronic diseases increases significantly and, among these, dementia stands out being a risk factor for disability and functional loss, promoting a relationship of increased assistance personal care. The progressive deterioration in cognitive and functional evolution of dementia care implies that can be reversed in growing burden of direct family and formal caregivers. This project aims to capture the general perception of formal and informal caregiver forward to their daily lives, overload and its quality of life, and specifically identify the occupations / activities that kept the caregiver and left after taking care of the relationships as well as establish possible correlations with quality of life and care in overhead rates. To this end, we selected a sample of 22 caregivers of patients with dementia diagnostic process, treated at a health facility in the city of São Carlos. These elderly caregivers were contacted 6 and 16 formal caregivers. For data collection where the following instruments were applied: Characterization Questionnaire caregiver, Occupations List, Disability Assessment Scale for Dementia - DAD, and WHOQOL Abbreviated and Scale Zarit Burden Interview. For data analysis descriptive statistical analysis was performed for each variable. From the data collected can be proved in this study that there is an abandonment of daily activities by these carers in productive activities, leisure and self care, and changes in quality of life and levels of overhead, observing differences between formal and informal caregivers.

This dissertation is a compendium of four scientific papers. Each paper describes a stage of the study, with the final goal of evaluating the effectiveness of different materials to increase parents knowledge on abusive head trauma. The first paper describes a review of national and international literature, which aimed to give a current overview of abusive head trauma (AHT). According to the review, AHT can be defined as injury to the skull and intracranial contents to a child due to a sudden unintentional impact and/or a violent shaking. It occurs mainly with babies and children under 1 year of age and can result in serious consequences for children's development, including death. Although there are specific signs for this type of abuse, it can be mistaken for common child illnesses or accidental head trauma. Thus, it is essential that health professionals are trained for the correct diagnosis. One of the main factors associated with its occurrence is the baby crying, which highlights the need for intervention with parents in order to teach them about child development and safe strategies to deal with the baby. The second paper aimed to investigate the knowledge of newborn parents about some characteristics associated with AHT, such as the pattern of the infant crying in the first months of life, strategies to deal with the crying baby and the consequences of shaking a baby. The results indicated a lack of knowledge about the severity of shaking a baby, as well as a possible Brazilian belief that babies should not be left crying alone. In this sense, there is a need for these issues to be addressed in AHT prevention efforts. The third paper aimed to investigate the belief of Brazilian parents about corporal punishment to infants, and its possible relation with abusive head trauma. As opposed to the international literature, participants of this study did not consider shaking as an appropriate strategy to discipline the baby, agreeing more with this strategy when it aimed to sooth the baby. Furthermore, the results indicated that the caregivers evaluation about the strategy s harm potential seems to influence its adoption in discipline and soothing contexts. Finally, the last paper describes the evaluation of the effectiveness of three different informational materials to increase knowledge of Brazilian parents about this type of abuse. The materials consisted of a video on abusive head trauma, a pamphlet individually read on the AHT, and a video on child safety, unrelated to AHT and used for comparison purposes. The results suggest that reading the pamphlet could be a useful strategy in prevention programs, since it increased participants' knowledge about the severity of shaking a baby, as well as the likelihood of using strategies to distance themselves from the baby when stressed by the crying. Although less significant, the results of the group who watched the video on the AHT also indicated an increase in knowledge about the average number of daily hours of baby crying. It is hoped that the results found in this dissertation will guide future AHT preventive efforts in Brazil.

The aim of this study was to evaluate the properties of briquettes made from charcoal fines bonded with paraffin. To prepare them were used three fractions of fine coal (20, 35 and 60 mesh) and a binder, the paraffin. Initially, the coal was fragmented into small pieces, milled and sieved and the fines thus produced were mixed and homogenized to the binder in a proportion of 15, 25 and 35%. The mixtures were taken to the oven, so the paraffin is melted and then taken to a laboratory hydraulic pressure where was applied a compression force of 1250 Kgf.cm-2 for 30 seconds. According to the results, the briquettes produced had an increase in heating power in accordance with increase in the content of binder reaching 8588 kcal.Kg-1 in briquettes bound with 35% of paraffin. The ash content was not affected by the binder since the paraffin produces no ash in the process of combustion. It was also accomplished the combustion index test using a combustion device, where temperature vs. time graphs and mass vs. time graphs were generated in order to learn more of its properties in the combustion process. The mechanical strength was indeed an important feature provided by the binder paraffin to the briquettes reaching a diametrical compression strength of 0.785 MPa, significant value compared to the lack of resistance in the briquettes without the binder, and generating fine in percentage of 5.38%, showing high mechanical strength, essential property in the process of transportation and storage. The assay distribution in paraffin briquette showed that the binder migrated to the edges, characterizing it as a binder type film. The higher the content of paraffin binder, the lower the moisture content of the briquettes. The moisture absorption was minimal with average values of 5%, presenting the moisture protection provided by the binder

This paper try to analyze the characteristics of training the Goiano Southeast Libras interpreters, about deafness knowledge / Libras and check the limits and potentials observed by them for their work with deaf students from the elementary school and / or high school. In this perspective, this research is an exploratory study of the Libras interpreter s condition in southeastern state of Goiás, realized from documental analyze and mix questionnaire, which try to find answers to the following question: what is the training of Libras interpreters in Southeast Goiano and what are the limits and potentials observed by them for their role as interpreters from this training? This paper talk about eleven participants who acted in Basic Education in state schools. The analyzes obtained about what the performers say about their training show us a lot of important aspects that interfere with their professional activities, such as, absence of training covering concepts about deaf education and the role of Libras interpreter; learning based in isolated signals, in short courses whose focus is to teach the language to be user; professionals working in a school with deaf students as if they were experts in the language, and validation of them performance based on hours of study and a certification acquired (or not) after being approved in a test performed on an organ of the state government.
