The harmonic injection technique can provide an electromechanical system with a conjugate gain in a machine with a larger number of phases in its stator. Thus, threephase machines of larger dimensions can be replaced to meet the need for high conjugates. This work can contribute significantly in systems in which a greater efficiency is necessary, being possible to obtain a system with greater conjugated occupying a smaller area. This work proposes a mathematical modeling and activation of an asymmetric nine - phase induction machine, in order to verify the increase of electromagnetic conjugate with harmonic injection. The mathematical model was developed in a complete way, presenting the equation for all the harmonic components. Subsequently the conjugate gain was verified through computational simulation and experimental procedure. Tests were carried out with different configurations of the eneaphasic machine, at the reference voltage and at the stator connections, each situation being evaluated individually. Under these conditions, it was evaluated in which situation the e-phase machine presented a better performance.

Esta pesquisa tem como objetivo gerar uma ferramenta de análise a avaliação de qualidade bioclimática para projetos de habitação de interesse social na cidade São Luís, localidade de clima quente úmido ao nível do mar, baixa latitude e sem desconforto por frio. O quente-úmido é considerado, pela bibliografia, o contexto climático de maior dificuldade no desenvolvimento do projeto bioclimático (passivo), seja pelo desconforto do clima, seja por questões socioeconômicas que dificultam a implementação de soluções ótimas de projeto. Este cenário de grande desafio torna-se mais complexo quando, nos anos 2000, é investida grande quantidade de recursos públicos para os programas federais de habitação de interesse social, nos quais, na ânsia de produzir números para a justa redução déficit habitacional, ignora-se as questões mais básicas do projeto bioclimático, tanto na escala do edifício quanto na escala do conjunto. O desenvolvimento da ferramenta proposta se dá com a sua aplicação em estudos de casos na área do Turu, em na cidade de São Luís, Maranhão, com a contribuição de casos internacionais em contexto climático similar, aos quais são aplicadas análises quantitativas e qualitativas. A pesquisa situa o projeto local junto aos parâmetros que indicam cumprimento aos requisitos bioclimáticos da bibliografia, e também junto aos projetos internacionais, que apresentam, teoricamente, soluções melhores. Os projetos locais foram analisados e avaliados segundo tais critérios. A partir dos resultados, possível afirmar que os projetos locais avaliados possuem similaridades entre si, e apresentam preocupação insuficiente com o bioclimatismo nestes projetos, especialmente na qualificação do edifício e do espaço externo. No entanto, há potencial de reabilitação em alguns itens, especialmente na escala do conjunto. O principal produto desta pesquisa uma ferramenta fundamentada na boa prática de projeto bioclimático apontada na bibliografia, desenvolvida de forma que possa, posteriormente, ser utilizada para auxiliar projetistas a melhorar a qualidade bioclimática dos projetos e legisladores a elaborar diretrizes e cartilhas que regulem de forma mais precisa a qualidade bioclimática, e, consequentemente, ambiental na habitação de interesse social multifamiliar do contexto local analisado.

At the end of cultivation, the farmer has an expressive provision in the amount of crop residues, not rare, reaching a volume two to three times greater than the product of economic interest (grain, fruit, fiber, etc). The objective was to evaluate the rate of decomposition and release of N and K residues of maize (Zea mays) submitted to nitrogen and potassium fertilization on a Red Yellow Latossolo. The experiments of fertilization and decomposition kinetics were conducted in the years 2014 and 2015, respectively, in Chã-de-Jardim experimental area belonging to the CCA / UFPB in Areia-PB. The fertilization experiment was conducted following a randomized complete block design with 11 treatments and 5 repetitions, which were prepared using the exponential matrix Plan Puebla III, where he defined N doses (5; 30; 50; 70 and 95 kg ha-1) in the form of urea, and K (4, 24, 40, 56 and 76 kg ha-1) as KCl, plus an absolute control (without fertilizer) summing eleven treatments. Decomposition bags were used (litter bags), were installed containing agricultural waste corn (stem, leaf, and straw). Each interval of 30 days after installation, was carried out sampling a bag per plot, totaling 5 samples (30, 60, 90, 120, 150 days). Both the analysis of variance as to estimate the parameters of the exponential equation, we used the statistical package SAEG version 9.1. The productivity of the biomass of the corn response to nitrogen fertilizer (N) and potassium (K) in 2014 had a significant effect on different compartments of the plant. A reduction of 30.5% corn biomass residue, after 30 days of the soil incorporated. The nutritional status of the plant reflected in the rate of decomposition of waste materials in the soil.

The objective of this work was to determine the ideal neutral detergent fiber (NDF) content that positively increases the carcass characteristics and meat quality of Santa Inês sheep finished in feedlot. The experiment was conducted at the Experimental Farm of São Gonçalo dos Campos, belonging to the School of Veterinary Medicine and Animal Science of UFBA, between September and December 2016. Six hundred intact male Santa Inês sheep were used, with initial mean live weight of 17.0 ± 1.5 kg, distributed in a completely randomized experimental design (DIC), with 5 treatments and 12 replications, totalizing 60 plots. Diets were composed of hay and concentrate, and treatments were represented by NDF levels [20, 32, 44, 56 and 68%, Dry Matter (DM) basis]. There was dietary influence (p <0.05) on the carcass weight (PCQ) and cold carcass weight (PCF), where the PCQ was linearly decreasing and the PCF presented a quadratic form. The PCQ and PCF obtained lower values when submitted to the maximum level of NDF (68%), being the values 10.82 kg and 10.78 kg respectively, and the highest for the diets with 20% and 32% NDF levels, being 18.31 kg and 18.30 kg for PCQ and 18.26 kg and 18.27 kg for PCF. Diets with different levels of NDF caused a difference (p <0.05) in meat protein percentages, which presented a quadratic form with a minimum point at the level of 56.79%. Regarding the conformation of the carcass, the maximum inclusion point of NDF in the diet was found at the level of 29.24%, resulting in an approximate value of 4.18. As for fat thickness, the maximum inclusion point of NDF was found at the level of 33.53%, which did not significantly influence (p> 0.05). Santa Inês lambs fed feedlot can receive diets containing low levels of NDF without negatively affecting carcass characteristics and meat quality. The levels of 27 to 30% of NDF in the dry matter of the ration were the most suitable for sheep termination.

In the Brazilian semiarid, depending on the adaptation of cactus of edaphoclimatc conditions, this forage has been used on a large scale, becoming the main bulky power supply flocks. However, its use has been restricted to the dry season, with high costs of labor for cutting and supply directly into the trough. The form of crop can also compromise the potential for regrowth of cactus, since its use is uneven and distributed throughout the dry period. Thus the objective was to evaluate the chemical composition, microbial populations, the fermentation profile, losses in silage and aerobic stability of silage additives palm with urea and wheat bran. To maximize the palmais with application of conservation techniques. The experiment was carried out in the Forage Section of the Federal University of Paraiba. We used a completely randomized design with four treatments represented by different wheat bran levels (0, 5, 10, 20% wheat bran based on dry matter) and four replicates per treatment. For the aerobic stability test were made 32 silos with their bran additions, with and without the addition of 1% urea on dry matter, we used a completely randomized design, arranged in a 5x2 factorial arrangement with five four of wheat bran levels x or without addition of urea. The cactus is a cactus that had percentage of dry matter of 12 (% DM), buffer capacity 22 (mEq / 100 g DM) and soluble carbohydrate (120 g / kg of silage). These characteristics associated microbiology, pH and percentage of organic acids possibly favored its fermentation process. Their qualitative characteristics were also evaluated, palm presented neutral detergent fiber 31 (NDF%), crude protein 6 (CP%). These characteristics possibly favor the fermentation process ideal for silage palm.

The objective of this study was to evaluate the effect of concentrated supplementation with different crude protein levels on intake, apparent digestibility of dry matter and nutrients, ingestive behavior, nitrogen balance, blood plasma urea nitrogen, milk and urine, microbial protein synthesis and microbial protein efficiency of lactating cows under Tanzania grass grazing. Twelve lactating dairy cows (Holstein/Gir) with average initial body weight of 540 ± 44 kg were used, grouped in homogeneous blocks according to the milk production (mean initial MP of 25 kg day-1), lactating weeks (10 weeks) and parity order (primiparous/multiparous), distributed in three 4 x 4 Latin squares, consisting of four treatments (122, 142, 162 and 180 g kg-1 of crude protein) and four experimental subperiods of 21 days. For the total MS intake, pasture DM, EE, NDF, NFC, TC, TDN and feed efficiency (FE), no effect was verified (P>0.05). There was an increase in the intake of concentrate (P=0.003), crude protein in kg day-1 (P=0.005) and crude protein in g kg-1 PC (P=0.01) for protein supplementation with CP levels. The digestibility was not influenced (P>0.05) by the CP contents of the concentrate supplement. The behavioral variables, grazing, ruminating and leisure, did not change (P>0.05) for treatments of PB levels. There was a linear effect on N intake (P=0.005), urine eliminated urea (P = 0.058) and fecal N excretion (P=0.039) for treatments with concentrate CP. A quadratic trend was observed for microbial protein synthesis (Pmic) (P=0.0003) and microbial efficiency (EFmic) (P=0.0073). Protein supplementation with different levels of CP does not alter the intake, apparent digestibility of DM and nutrients (EE, NDF, CNF and CT) and does not modify the patterns of ingestive behavior of lactating cows under Tanzania grass grazing. The different CP levels for lactating dairy cows in Tanzania grass pasture provided an increase in nitrogen excretion in feces and urine, thus contributing to the environmental impact through the release of ammonia and nitrites in the soil. The microbial protein was influenced by CP contents.

The Go language is one of the newer current languages with an increasing popularity in the software industry. It is defined by a specification and implemented by two compilers with different proposals to ensure that the specification is correct and complete. The gc compiler focuses on quick compilation and few optimizations while gccgo focuses on using GCC optimizations without worrying about the compiling time that is spent. This work proposes a study with the objective of constructing a genetic algorithm that assists in the identification of situations that gccgo can be more efficient than the Go Compiler. Results show that the Go Compiler is on average 24.7 times more performance at runtime and with an average executable file size of 33.86 times greater than the generated gccgo executable using a subset of optimization options.

DAMASCENO, Herson Heracles Barreto. DICOMAddress: Modelo distribuído de endereçamento de imagens para uma infraestrutura de informação telerradiológica. 2018. Dissertação (Mestrado em Informática) – Programa de Pós-Graduação em Informática, Universidade Federal da Paraíba, João Pessoa, 2018. It is known that the use of teleradiology is increasingly present in hospitals and clinics and that studies are located between them via URLs.It is important to note that these studies need to be available for several years (decades) and such URLs must allow access to them in the future, even if the actual location of the studies has been changed. This work proposes a model for addressing studies (exams) of medical images for a teleradiological information infrastructure. It uses the Named Data Networking (NDN) protocol, whose basic premise is the naming of objects for their discovery and retrieval, that is, the addressing is no longer based on location and is now supported in the name given to each object. The objective of this work is to propose the DICOMAddress, a layer that makes the link between the DICOMFlow and the NDN implementation, the NDN Forwarder Daemon, for locating moved objects without modifying the workflow. It is intended to be incorporated into the DICOMFlow distribution protocol for medical studies, which is asynchronous, distributed and uses URLs to locate studies. This template is not intended to change the way images are transferred, but rather aims to name these exams so that it can generate a valid URL to transfer these images. For the validation of the model, a prototype was created where experiments were carried out in a simulated environment in order to validate the proposed model. It was concluded that the proposed model meets the needs of DICOMFlow and was successful in returning the URL with the location of the requested images.

ABSTRACT Paraíba is an important cement production centre in the Brazilian Northeast region, firstly remembered by this industry thanks to the pioneering of the first modern factory implanted outside the Southeast region, still in the decade of 1930. However, it is not very mentioned that the State had the first Portland cement factory in Brazil, still at the end of the 19th century, whose history has been explored in a fanciful way or reduced to a mere legal dispute. The objective of this work is to recount this history from its vestiges, with documentary and technical-scientific background, considering its short period of operation in 1892. In addition to the literature review on the technological evolution of cement production and product characteristics at the time, four visits were carried out at the ruins of the old factory, located on Tiriri Island, in Santa Rita, Paraíba. Data collect in situ techniques applied to Forensic Sciences were applied, since the characterization of the constructions by means of aerial photogrammetry – with elaboration of a 3D digital model – to the search, identification and collect of the cementitious traces essential to the study, aiming at the minimum intervention on site. Besides identifying the quarry and the remaining factory constructions, the first three visits were used to collect samples: clays and limestone; plaster mortars (plaster and bricks laying); traces from Dietzsch kilns inside materials; and an object of hydrated cement. The fourth visit was to record the location of this object in the context of the site and to remove it in order to preserve and analyse it in the laboratory. The samples of the raw material were characterized by X-ray fluorescence, whereas the traces of cementitious materials were characterized by X-ray fluorescence and X-ray diffraction. Kilns burnt material samples were also analyse by optical microscopy and scanning electron microscopy (SEM), including dispersive energy spectrometry (EDS). The comparison between the results of quarry samples and those of the cementitious remains were consistent, rejecting the mythical hypothesis. On the other hand, the analysis of the cement traces and their microstructural characteristics allowed to classify the Portland cement production in the island, in terms of the its qualitative evolution. Evidence obtained, along with other findings discovered during the research, allowed to emphasize the enterprise among its congeners and raise the remaining ruins to a distinct site of Industrial Archeology, still absent of protection and recognition as cultural heritage from Paraiba and Brazil.

The study of the Caatinga ecosystem dynamics, which includes the nutrient cycling process, through litter input and decomposition, the microbial activity measured through CO2 efflux, and the production of glomalin, an indicator of soil physical quality, makes It is necessary to know the specificities of this biome and thus propose conservation measures and appropriate management of the soils of these areas. This work aimed to determine in-situ CO2 efflux and easily extractable glomalin production in soil and its relationship with aggregation, to evaluate litter production and decomposition and nutrient cycling under tree and shrub vegetation in an area. of caatinga preserved in the dry and rainy periods. The work was developed at Professor Ignácio Salcedo Experimental Station, of the National Institute of Semiarid (INSA), located in Campina Grande - PB. A transect inserted in both environments was demarcated, the samples were taken in the tree and shrub environments and compared later, observing the interference of environmental factors such as precipitation, humidity and soil temperature under the studied variables. Collectors were installed to accompany the monthly contribution of litter. To evaluate the decomposition rate and nutrient cycling, litter bags were used, where the remaining mass was determined, and the N, P, K and C contents of litter released over 1 year were quantified. Monthly CO2 emission was evaluated by the closed-chamber static method and glomalin was determined by the Bradford assay and correlated with aggregate stability. The litter input was higher in the shrub area, and also the decomposition rate of the plant material was faster for shrub species compared to the tree species. The annual nutrient intake followed the sequence of N> K> P, and the highest nutrient inputs were in the dry season for both environments. The highest CO2 emissions were found in the shrubby environment. The easily extractable glomalin presented a seasonal pattern, where its highest values were obtained in the dry season, regardless of the vegetation type of the area. The highest content of Total Organic Carbon was found in the tree vegetation environment and the aggregate stability index was higher in the shrub environment. The highest correlation values were between IEA and COT. It was observed the strong influence of climatic factors such as precipitation, humidity and soil temperature under the analyzed variables.

Poultry farming is an activity of global importance. The United States of America and Brazil hold respectively the top two positions in world chicken production. The presence of multiresistant Salmonella isolates in chicken meat is a cause of worldwide concern for the public and animal health authorities, damaging the image and quality of this food. In the present study, 14 public genomes of Salmonella were selected from the NCBI platform: 8 Heidelberg (SH) and 6 Typhimurium (STM) serotypes originating from Brazil and the United States. These isolates were compared for the purpose of evaluating gene sets related to the antimicrobial resistance of these microorganisms. The results showed the presence of genes related to antimicrobial insensitivity, with high frequency for aminoglycosides (aac - Iaa) 100%, fosfomycin (fosA7) 50% (7 SH, 3 from Brazil and 4 from the USA), tetracycline tet(A) and sulfonamides (Sul2) 50% (3 SH from Brazil and 4 STM, 1 from Brazil and 3 from the USA) and 14.28% for beta-lactams (blaCMY-2)(2 SH from Brazil). Only 3 samples did not present a plasmid, whereas the rest of the isolates (11) had at least one plasmid. Among these, ColpVc, IncX1, IncA2, IncI1, IncFIB(S) and IncFII(S) were identified. Regarding the pathogenicity islands of Salmonella (SPI), SPI-1, SPI-2, SPI-3, SPI-4 and SPI-5 were found in all observed genomes, although some had low homology compared to the genome reference (SalmonellaSPI), with 4 SH and 1 STM from Brazil and 2 STM from the USA. Building the phylogenetic tree allowed to group the isolates into 3 clades that varied between the serotypes and countries from which they were isolated. SH cells found in Brazil showed more resistance genes when compared to those isolated in the United States and to STM isolates.

Investigating and knowing the vocal symptoms of the patient allows the speech-language pathologist a more complete view of their needs, since not always the vocal alteration identified by the clinician is perceived with the same intensity by the patient. In this context, the Vocal Tract Discomfort Scale (EDTV) was developed with the objective of measuring the intensity and frequency of vocal tract discomfort symptoms, filled by the individual himself, through the use of qualitative descriptors. The Item Response Theory (TRI) can be used in the validation of the EDTV in a satisfactory way, considering each item individually, without prioritizing the total scores to characterize the attribute studied. Thus, the objective of this study was to develop a decision model based on the application of the Item Response Theory (TRI) in the Vocal Tract Discomfort Scale (EDTV) protocol. It is a documentary, quantitative, descriptive and cross-sectional research. The database (BD) of this research was formed from the insertion of the demographic variables (sex, age, profession), laryngeal diagnosis, auditory perceptive evaluation performed by a specialist voice judge and EDTV item item. All these variables were extracted from the charts of 310 patients belonging to the Integrated Laboratory of Voice Studies (LIEV). Descriptive and inferential statistical analysis was carried out, from the Exploratory Factor Analysis (AFE) and Confirmatory (AFC) and the TRI. The sample of participants was composed of patients of both sexes, with a mean age of 39.36 (SD = 15.80), being the majority female and non-professional voice. It was observed, through the AFE, that the items of the EDTV were organized in four factors, according to inter-agency correlations. Regarding the AFC results, the EDTV items were organized into three factors, since the last two factors found in the AFE correlated and constituted a single factor. Thus, as a final solution of the AFC, the EDTV was organized in: Factor 1 called "Hybrid" formed by the items corresponding to the frequency and intensity of the symptoms of burning (F1 and I1), sore throat (F4 and I4) and irritated throat (F7 and I7); Factor 2, called "Inflammatory process / tissue injury", formed by the frequency and intensity of symptoms of itching (F5 and I5) and sensitive throat and Factor 3, "Musculoskeletal discomfort", formed by the items of frequency and intensity of the tightening symptom (F2 and I2), dryness (F3 and I3) and ball in the throat (F8 and I8). Regarding the TRI data, it is possible to affirm that the EDTV items, from the result of their parameters of difficulty and discrimination, were adequate, even taking into account that some items had to be excluded from the analysis, this may have influenced in the ability of some factors to cover the entire extent of the latent trait. In general, the research was completed with two factors that presented the best psychometric parameters, "Vocal hyperfunction with phonotraumatic lesion" and "Vocal hyperfunction without phonotraumatic lesion", and the items excluded from the analysis - itch and sensitive throat - were the factor Inflammatory process / tissue injury, which were not included in the TRI analysis. It is concluded that the EDTV presents itself as an instrument that brings the understanding of discomfort and can be considered valid and accurate for the vocal selfevaluation, being able to be used for research purposes and complement in the diagnosis with items with good psychometric qualities.

Zinc stannate (Zn2SnO4) and magnesium (Mg2SnO4) spinel were combined in order to obtain a solid solution (Zn(1-x)Mgx)2SnO4 in compositions x= 0; 0.25; 0.50; 0.75 e 1.0, using the modified-Pechini method, in order to evaluate the influence of the Zn2+ ions substitution by Mg2+ones in the spinel lattice for application as photocatalysts and antimicrobial agents. Photocatalysts were characterized by the X-ray Diffraction (XRD), Infrared Spectroscopy (IR), Ultraviolet-visible Spectroscopy (UV-Vis), Raman Spectroscopy, Fotoluminescence Spectroscopy (PL) and surface area measurements (SBET). XRD results showed that the materials presented a high long range order. The substitution between the metals in the crystalline lattice led to the existence of additional Raman modes, infrared band displacements, increase in band gap values and different photoluminescent emission profiles in the visible spectrum, varying the region from lowest to highest energy with the increase in Mg2+ in the structure. Zn2SnO4 presented greater short-range organization. Some parameters were evaluated in the photodiscoloration: catalyst calcination temperature (800 and 900 ° C), different dye concentrations (10, 20 and 40 mg.L-1) and pH (3 and 6). The results showed that the solid solutions presented excellent results. For the intermediate compositions the efficiency can be attributed to its high surface area, reaching 90% in times less than 3 h, even with double the concentration and decrease of the pH of the solution. For Zn2SnO4 it may be related to lower distortion making electron-hole recombination difficult. In relation to the antimicrobial tests, the intermediate compositions were efficient in inhibiting the growth of the bacterial strains against the bacteria Staphylococcus aureus and Escherichia coli, being the Gram negative more sensitive to the inhibitory action of the materials, being able to be attributed to the greater negative surface charge.

Schiff’s Bases obtained from the derivatives of Isatin, have been calling researchers attention, in the field of medicinal chemistry, to their broad profile of pharmacological activities, such as anticancer, antimicrobial and antiviral. Recent studies have demonstrated a potential selectivity in the inhibition of COX 2, an enzyme responsible for inflammatory symptoms. In addition, they are present in important biological processes. This work was carried out with the aim of synthesize 12 Schiff’s bases derivate from isatin, being 6 unpublished, with potential biological activity. Initially, 11 intermediates derived from Isatin were synthesized using nitration, halogenation and alkylating reactions with yields varying from 51 to 93%. Subsequently, the Schiff’s bases were synthesized using microwave irradiation as a heating source. The methodology used was shown to be simple, fast and efficient for obtaining the products, showing good yields, income ranging from 57% to 98% in reaction times of 30 to 60 minutes. The products were characterized by infrared spectroscopy (IR) and MRI 1H and 13C.

Inserting environmental variable into organizational processes through innovative actions that reduce its impact on environment and continuous performance evaluation in search of competitive advantages becomes indispensable for continuity of organizations owing demands of society and regulatory bodies. In this scenario, a diversity of environmental practices are adopted promote by dynamism of environment in which they are inserted, and the organizational life cycle theory is discussed in the literature as a way to understand specific variations of the firm. Based on assumptions, the research was conducted by analyzing the organizational characteristics of environmental management through environmental practices and monitoring based on life cycle theory. The research was realized through a questionnaire, with companies that have environmental certifications active in Brazil, obtaining a sample of 112 companies. The profile of respondents includes companies with a potentially high potential level of pollution risk, with a market time of over 20 years and in growth stage. In understanding of distinct environmental practices and organizational characteristics was observed greater statistical influence in stage of life cycle. It was also verified that managers' understanding of environmental practices and the degree of monitoring through indicators, oscillate according of the stage that organization. As characteristics at each stage, was observed that at birth, organizations only develop environmental awareness practices to obtain competitive advantages and have very low use of indicators to monitor their practices. In growth, environmental practices are mainly aimed at improving reputation with greater use of operational indicators, reflecting an internal discipline of environmental issues. In maturity, the practices are a great propulsive in reach competitive advantages, majority management indicators being used, but not use operational indicators to monitor water and atmospheric emissions from its activities. In revival is highlighted as a stage of more sophisticated practices, including Research and Development (R&D) with focus for developing cleaner products and processes and more use of operational indicators, reflecting coherent environmental management. Finally, the declining reflects a lack of credibility that environmental practices can drive the company into competitive advantages. In research has demonstrated evidence in understanding of environmental management supported by the life cycle theory and, although companies believe that environmental practices can conduct to competitive advantages, there is incoherence of how they perform the monitoring through indicators, reflecting impossibility to measure and reflection of practices in their environmental performance. In this way, life-cycle theory can sum to interpretations of environmental issues and organizational performance, capturing specific internal and external variations needed to direct environmental management to improve performance.

This research analyzes the functionality and usability of the Flipboard news application specifically for the visually impaired public, in two aspects of initial appeal: the employability of the design and the search for consumer confidence from the reinforcement of importance of the credibility between the news selected for it by the application. In order to reach the objective, an analysis was made of the application's functions, including accessibility, punctuated from theoretical concepts and practical concepts, among them the application of observation of the use of the same by people with visual deficiencies. It has been discovered that in addition to the incessant search for the exact selection of news for each consumer in a personalized way from computer algorithms, there is a latent concern with the elimination of news that may be untrue and with the design employed in all stages of the process of news reading. One of the questions developed here is: does the functionality of this design also apply to the visually impaired public? It has been possible to identify that Flipboard is a business model focused on the premium consumer and that somehow reconfigures the mode of production and dissemination of news, based until then on the industrial model, but does not present itself as a completely accessible product for people with visual impairments.

In this work, the creation of compositions based on accessibility criteria of the performance is proposed. The approach is mainly directed towards beginners and new comers to the field. The creative process presented is based on a critical reflexion on the musical status quo in a contemporary context, especially regarding some of its possible relations to an inaccessibility of the musical practice. Three compositions developed on the course of this research were performed by beginners to assess the possibilities of the proposed approach.

This thesis analyzes the education management policy in the State Schools of the State of Paraíba-Brazil, focusing on the evaluation, embodied in the Ricardo Vieira Coutinho government, Brazilian Socialist Party, (2011-2014 / 2015-2018). It assumes, as a theoretical and methodological reference, the philosophy of praxis, from the categories: contradiction, historical block, organic intellectual, traditional intellectual, hegemony and counterhegemony. It seeks to answer the following problem: how is the human training project based on education management that prioritizes evaluation, in the context of neoliberal hegemony? It is based on the assumption that the education management policy in Paraíba prioritizing the dimension of evaluation, expressed through the Evaluating IDEPB and the School of Value Prize, reflects a human training project that adjusts the subjects to the context of neoliberal hegemony of organization of capital. The research has the general objective of analyzing the education management policy focused on the evaluation and the human formation project in the context of neoliberal hegemony, starting from the Evaluating IDEPB and the School of Value Prize, instituted in the Ricardo Vieira Coutinho government (2011- 2014 / 2015-2018). The specific objectives are: to analyze the emergence of the evaluation policy in the scenario of crisis and the restructuring of capitalist sociability; to problematize the theoreticalmethodological assumptions that conceive the management policy, focused on the rating from the Evaluating IDEPB and the "School of Value" Prize; to explain the human training project from the politics of education management through the voices of the subjects. From the voices of the subjects, the tensions and confrontations that reveal the contradiction of social reality and education mediated by organic and traditional intellectuals that construct their educational practices related to the interests of the class are represented. In this sense, evidence and clues are indicated that indicate the resistance by the social subjects of the schools, signaling that, although a formative project is under construction in the context of neoliberal hegemony, a counter-hegemony must be built.

This present research is a study of case and it investigates the theme Continuous Training for teachers of Young and Adult Education (EJA), in light of the principles of popular Education. Thus, it aims to analyze the elaboration, the development and the repercussion of a Formative Proposition with the teachers of EJA in Municipal School of Infant and Fundamental Education Damásio Barbosa of Franca in João Pessoa. This is a qualitative investigation, based on the cycle of the action-research (Thiollent, 1986;Tripp, 2005), being used for collecting technical data, such as the participant observation, the field journal, semistructured interviews. As well as the evaluation of materials, such as narratives, texts written by the teachers during the meetings of continuous training and school documents, such as the Political Pedagogical Project and the documents of pedagogical guidance. The analyses of the collected data have been done in light of the content analysis technic, by Laurence Bardin (2011), confirming the theoretical and empirical hypothesis, built along the stages of investigation-action, we have concluded that the paradigm of the Popular Education consists of an alternative and powerful way to create new possibilities, through the articulation of the multiple experiences and knowledge that lie on the ground of the Public School. Participating dialogistically in the space of reflexion -action about the pedagogical practice, provided the educators with the possibility of rethinking their own training, reconfiguring their place in the daily construction of a popular public education, involved with the subjective needs of the young and adult students, concerning the social and cultural complexities of the present time.

The work of Escola Viva Olho do Tempo - EVOT, a non-governmental organization located in Gramame Valley, is collectively built by a significant group of people, groups and entities, mobilizing professionals, institutions, partnerships and support from various areas and various City. However, the objective of this research was to identify and analyze the practices of the twelve educators who live in the community and assume the shared management of the entity. This study sought to understand, from the educational practices of EVOT, how these residents construct educators and educators, and also seeks to make them visible as authors and authors of these processes. The legacy of Popular Education and Paulo Freire articulates with these practices that move anchored in dreams, cares and shared works, important elements that mobilize these subjects for the pursuit of happiness of every day. We have identified that the cultural sources of the educative practices of these educators present an intense rooting in the territory and a strong relational aspect, important elements to rewrite the world and to rewrite the word with knowledge and actions developed by the local people. The educators take ownership of the place, if they perceive protagonists of these constructions and value the relations and the collective forms found to occupy and to strengthen the territory. The educational practices are revealed in movements of joy, celebration, freedom, care, dreams, utopias (FREIRE) and realize an education that, dialectically, supplies itself and produces collective life (BRANDÃO), in a strong identity relation with Gramame Valley. EVOT's practices, therefore, point to the deconstruction of this exclusionary hegemonic neoliberal model, in which individualism is the rule, and exercises, based on the Griô Pedagogy, an education based on the dialogical relationship, on the sharing of knowledge among the generations, on the appreciation of masters and masters of oral tradition, local culture and care for the environment. The experience hereby studied can contribute to the discussion of processes through which subjects can discover and rediscover themselves from their own references, appropriating knowledge that is connected to the context in which they are inserted and points to the need to think in strategies through which local subjects can occupy the public school to exchange knowledge and actions. This study also raises a reflection on the importance of discussing the meaning of popular education for the relationship between public education and the diverse experiences of civil society with its practices, subjects and local knowledge, building dialogues between the knowledge of written tradition and oral tradition.
