The interaction of art with thedigitizationofthemediageneratesacomprehensivespectrumofdigital art. Within this spectrum, will lectured on glitch art, a digital art form that works with the intentional introduction of errors in his works of art. Specifically, digital media was studied to make a creative production, using, subverting or listing solutions for artistic creation through computing. We developed a computer program using the visual programming language Pure Data, which transforms the process of creating glitch art into something practical for the artist, showing results that can be explored visually and with less delay. This new method offers less risk of destruction ofthefilesand reduces the computational knowledge load necessary to cause a failure with artistic intention. Additionally, we investigate the possibilities that this glitch facilitator creates for new interactions within the two fields of knowledge focused on this project: art and computing.

This research deals with Education in countryside in the area of Higher Education directed to the subjects who live/work in the countryside through the experiences of Programa Nacional de Educação na Reforma Agrária - PRONERA (the National Program of Education in Agrarian Reform) which is the analysis object of this work. Therefore, the main object of this research is to analyze the repercussions of PRONERA on the social, professional and political performance of those who graduated (got degree) both offered at the courses of Pedagogy and History at the Federal University of Paraíba – UFPB (campus I). The research seeks to meet the following specific objectives as: analyzing the statistical data published in the II PNERA report, regarding the provision of higher education to the settlers of the Agrarian Reform in Paraíba; and identifying the repercussions of PRONERA on the social, professional and political performance of people who got graduated in the Higher Education courses offered at UFPB. This study is characterized as a qualitative research and the repercussions which were analyzed along the text are based on the Dialectical Historic Materialism perspective. Therefore, this work was also based in complementary methodological procedures such as bibliographical and documentary research and interview of those who graduated at the Program. Our focus on this research of these courses allowed us to discuss the history, concept and practices of Education in the countryside area, and allowed us to discover the reach of PRONERA in the life of countryside people. Therefore, we understand PRONERA Program as an educational proposal based on a peasant perspective, and this program had positive repercussions on the countryside people lives, increasing the level of schooling, promoting the continuity of studies, making possible the professional insertion, permanence in the countryside area and the valorization of family agriculture, fomenting discussions and practices of Education in the countryside area in the schools of the settlements, strengthening the peasant identity and providing the political engagement and the strengthening of the political action in social movements.

Health-Care Waste (HCW) management seeks to adapt handling procedures to legal and regulatory requirements based on waste segregation and reduce the generation. The HCW are those generated in establishments providing aid to human and animal health and although it represents a small percentage of the total solid waste generated in a municipality, it constitutes a portion that represents a risk to human health and the environment when handled in an inadequate manner. With the objective of evaluating the conditions of HCW management, including the steps of segregation, identification, internal transportation, treatment and final destination, a study was carried out on a sample of 18 hospital establishments located in the city of João Pessoa / PB, those 18 establishments correspond to 72.6% of the existing beds in the State. The facilities of two incinerators located in the State of Paraíba were visited for this study. Interviews were conducted in which managers of health-care centers answered a questionnaire prepared and later approved by the Research Ethics Committee of the Lauro Wanderley University Hospital (nº. 2.101.418), and the waste management steps evaluated from a checklist. The results showed that the main difficulties were the incorrect segregation of HCW groups and subgroups; the unfulfillment of elaboration of a health services waste management plan; the wrong storage of infectious waste; the structural deficiencies on the external waste warehouses. In relation to external collection, common wastes were collected by the public cleaning agency and association of recyclable materials. On the other hand, the collection of Groups A, B and E was, in all cases, outsourced and performed by a company specialized in the treatment of HCW. The priority treatment was the incineration and disposal of the ash occurred at Campina Grande Municipal Landfill and at the Waste Treatment Plant of Pernambuco. It is concluded that despite the observation of adequate practices in the intra-establishment management and correct final destination of the infectious and piercing parcel of waste, hospitals must still move forward in order to obtain an adequate situation of the establishments located in the municipality besides the need to improve the data base, mainly in relation to the quantity of waste generation.

In this master’s thesis, fuzzy grouping methods are presented in the space of featuresbasedontheMahalanobiskernelwithadaptivequadraticdistances, labeledrespectively by (KFCM.FS.GD, KFCM.FS.GF, KFCM.FS.LD e KFCM.FS.LF).This study is an extension of the work developed in [26]. The proposed methods were based on the Mahalanobis kernel from adaptive quadratic distances defined by defined positive symmetric covariance matrices. These matrices of covariances are diagonal and complete (not diagonal), common to all groups and different for each group, determined under the clustering approach in the feature space, which performs a mapping of each observation by means of a nonlinear Φ and then obtain the centroids of the groups in the resource space. This technique allows that when we move to a space of higher dimension (space of characteristics), a set of observations in the non-linearly separable input space becomes linearly separable in the space of characteristics. The proposed algorithms were compared with the various traditional clustering methods known in the literature, such as fuzzy k-means and their versions based on the Gaussian kernel, as well as the methods developed by [26]. The evaluation was performed through numerical experiments with simulated and real data.

This research had as general objective to analyze the participation and / or absence of participation of the administrative staff of the Education Center, in the Quality of Life in Work Program organized by the Vice-Rectory of People Management of the Federal University of Paraíba. In this sense, the work intends to problematize issues related to public management in higher education, within the framework of actions in the field of human resources. We sought to understand how this process of participation in its multiple and complex aspects occurred in the universe of the institution and to understand the dynamics of the elaboration and implementation of the Quality of Life Program within the scope of the aforementioned locus. In methodological terms, questionnaires were applied to the technical-administrative servers of the Education Center. The results of the research pointed out several problems in relation to the design of QWL programs, which do not stimulate the actors' actions as participants in the planning of actions. This distancing results in a low participation of the servants, although the same ones reveal a desire of involvement with subjects of this nature.

The growing search for biofuels aims at the use of renewable raw materials in order to avoid the scarcity of non-renewable materials, as well as all the environmental problems resulting from their use, such as the emission of greenhouse gases. In Brazil the most commonly used biofuel is ethanol from sugarcane, but there are others such as biogas and biodiesel. The production in the sugar and alcohol industry is seasonal due to the raw material, so that the mills spend approximately four months a year without producing, this time called the off-season. Biomass is targeted for this production because it has a high sugar content in its lignocellulosic composition. The environmental problems arising from industrial waste are a global reality, many waste from the food industry is not used and end up returning to the environment in the form of pollution. There is a need to reuse these wastes in order to avoid the degradation of the environment. The present study aimed to evaluate the juice of the pineapple peel which is abundant in the region of Paraiba, as raw material for the production of hydrous ethanol, with the main objective of demonstrating that the sugar and alcohol industry can use this residue in its plant for a possible reduction of the off season The parameters analyzed before and during the fermentation were: Acidity, SSS, pH, ART, AR, POL, purity, conductivity and alcohol content, as well as bacterial contamination and viability of yeast during fermentation, and for initial adjustment of the bark juice SSS was used the residual molasses of the sugar mill Agroval. The average fermentation efficiency was 84.23%. Hydrated ethanol with an alcohol content of 94.8 MPa (% m), acidity 13.7 mg / L, conductivity 64.6 μs / m and specific mass at 20 ° C of 804.7 kg / m 3 were obtained. in accordance with the standards established by the National Agency of Petroleum, Natural Gas and Biofuels - ANP.

Whereas that energy consumption has been showing continuous growth, the increasing search for sustainable human development practices is present in the generation and use of different energy sources. In this context, it justifies the expansion of research and studies related to the improvement of new materials used in the exploration of renewable energy sources, such as termosolar. Therefore, the present research deals with the making of selective absorbing surfaces (SSAs) based on CrO3 through electroplating in 304 stainless steel and the evaluation of the influence of the substrates treatment on the films optical properties. To this end, three main steps constituted the methodology applied: substrates treatment, coatings (films) deposition and physical-chemical characterizations after deposition of the coatings. The first step was performed by three methods: cleaning by detergent (DC), acid treatment (AT) and electropolishing (EP) of the substrates. Hereafter, coatings electroplating was carried out, where an electrolytic bath containing CrO3 was prepared for the deposition of chromium on the substrates with deposition times of 1 min, 2 min, 5 min and 10 min. Then, the films were characterized by: Profilometry, Spectroscopy in the UV-Vis-NIR regions, Scanning Electron Microscopy (SEM) and Spectroscopy in the IR (infrared) region. Finally, the results obtained indicated that SSAs were obtained and the electropolished coatings (EP) presented better optical performance than other samples (DC and AT), with solar absorptivity values around 98% and thermal emissivity of approximately 7%.

Smart grids are increasingly present to improve the energy efficiency of the electrical network and several equipment are fundamental in this process, among them smart meters. Such devices accumulate an enormous flow of information that can be analyzed to aid in the decision making of the electric system controllers. This makes the concept of Big Data Analytics present, capable of processing various data and correcting atypical values, called outiliers, through algorithms using artificial intelligence, such as Fuzzy logic and Artificial Neural Networks. As a way of improving existing results, the present work suggests the use of a hybrid algorithm, the Adaptive Neuro Fuzzy Inference System (ANFIS). This algorithm showed better performance in the correction of outliers when compared with techniques based on Artificial Neural Networks and Linear Interpolation. Finally, results of the estimations will be presented using real energy demand data for a substation of electricity distribution.

Due to the constant growth and technological advancement of the electrical system, emerged electromechanical oscillations inherent in its operation. These oscillations are responsible for causing instability to the system as they limit the ability to transmit power as well as increase the risk of non-scheduled stops. The main objective of this work is the damping of electromechanical oscillation in power systems of three areas, aiming to achieve the robust stability of the system. For this, it will be used techniques of analysis and design of controllers for multivariate systems in frequency domain, to investigate the feasibility of achieving robust control from decentralized controllers of reduced order. The selection of the most important input-output series for the system is imperative for the controllers applyed, to achieve robustness. For this, the techniques of metric analysis were used: matrix research and analysis of the singular values. The techniques of analysis were applied to a load-frequency system of three areas. The controller is type ∞ and the method of aplication in this work, to obtain th robust control os the system, was the particle swarm optimization (PSO). The results obtained are satisfactory due to the robustness of the control and the damping of the oscillations of the system.

This work aims to determine a linear or non-linear relationship between the Infant Mortality Rate (IMR) and a set of socioeconomic and coverage variables observed by the federative unit of Brazil from 2005 to 2010 using the panel data model (Panel Data ) linear and non-linear considering the fixed and random effects. The results show that the most suitable model is the fixed effect with logarithmic transformation in the dependent and independent variables. The dependent variable was the IMR and the independent ones: illiteracy rate, GDP per capita, proportion of people with low income, percentage of the population served by water supply network and the proportion of the population served by garbage collection. The nonlinear Binomial Negative models did not present satisfactory convergence in the estimation of the parameters for any model. The Poisson nonlinear model showed convergence only in the Pooled OLS and Randon (Random Effect Model) models. The conclusion obtained is that the independent variables that have a significant impact on IMR are illiteracy rate, per capita GDP and proportion of people with low income. R software was used to perform this data analysis with the plm and pglm packages.

The study presented in this paper was aimed at uncovering the most relevant social relations contributing to the creation of a self-organized popular education school in the Elizabeth Teixeira (ET) encampment in Limeira (São Paulo), whose construction was inspired on the fight for Agrarian Reform undertaken by Brazil's Landless Workers Movement (MST). In this sense, the school was understood as a unification of multiple determinations that constituted the camp itself, where the SelfOrganization and Popular Education elements were seen as roots and fruits of this process, simultaneously projecting themselves as technical categories and serving as foundations for this study. The analysis considered mainly the relationship between the three following collective subjects: the inhabitants of the Elizabeth Teixeira encampment, the MST and Universidade Popular (UP), a collective project conducted by popular educators. UP’s reports and accounts were used as source for the present research, as well as videos recorded by encampment supporters and memories recalled during the Círculos de Memória Investigativos (meetings of investigative memory) organized with groups which took part in the construction of the school. The study revealed that the school (or “escolinha”, “little school”, as it’s called among participants) is a hub of forces that helps maintain the vitality of the encampment. The popular feature of the educational process analyzed became evident through some of the paths taken from collective decisions that attempted to deal with issues arising during the process of construction of the school. This popular characteristic rebuilds the meaning of “public” in a space that in nine years has never been legally recognized by the State.

Under the socially responsible management business is geared to the precepts of ethics and transparency, both in the domestic and external environment. The production process of companies requires actions and good practices in the management of social and environmental aspects. Social aspects the occupational safety and health are entered as a relevant variable in the concept of Social responsibility. As for the environmental aspects of the waste generated in the production process are also a relevant variable that interacts and influences in the field of Social responsibility. This study presents the degree of influence of occupational health and safety management and construction and demolition waste in Social responsibility in a construction company. Qualitative methods were represented by a semi structured interview questionnaire, and a script that was used for observation in the construction site and quantitative methods, using statistical tools such as descriptive exploratory data analysis and nonparametric methods. Qualitative and quantitative results of this research have been achieved through the model of Social responsibility indicators related to occupational health and safety management and the management of construction and demolition Waste being structured the dimensions in the light of the PDCA cycle. Average scores were calculated for each dimension studied and these proved less than the stipulated maximum average, that is the company object of this study is not considered as a socially responsible company.

In order to increasing the understanding of the factors that influence the implementation multi-plant improvement programs (XPS), this study aimed to analyze the knowledge and organizational practices transfer process on XPS implementation among a subsidiary and its local suppliers. In order to accomplish this, a structured literature review was conducted to identify the factors that influence the process of knowledge and organizational practices transfer. Based on this review a framework was proposed with twelve theoretical propositions. The framework was applied conducted in a multiple-case study with four local suppliers and an automotive multinational subsidiary, all of them located in Pernambuco/Brazil. The empirical data was gathered from semi-structured interviews, direct observation, organizational documents and published papers. The data analysis was conducted by using a computer-aided qualitative data analysis assistant (software Atlas.ti), for management and categorize the collected data. The results highlighted the positive influence of the motivation and transfer ability of the source unit to share the XPS; the value and the type of knowledge and practice stock; the richness of personal, socials and organizational transmission mechanisms on XPS implementation; the motivation of target unit to receive the XPS and the organizational and relational context between the units on XPS implementation. However, the empirical data provide partial support to the influence of the social context and the absorptive capacity of the target unit on XPS implementation. Furthermore the results show that some subfactors were interrelated. This is an exploratory qualitative study limited to analyze four local suppliers and an automobile industry with a theoretical framework potentially testable in larger scale. This study provides an overview of multi-plant improvement programs. Moreover, also can help managers in knowledge and practice transfer process on XPS implementation and contributes to the recent and fragmented literature about multi-plant improvement programs and XPS implementation.

Tensed the boundaries between art and contemporary architecture from the exploration of the environment as the work itself is the starting point of this dissertation that analyzes cases in the Inhotim Institute in which environments, places to be visited or even buildings altogether are results of collaborative design between artists and architects.

The concern of the construction industry with environmental issues has stimulated research aiming at the reduction of cement consumption in concrete. This is because cement industry is responsible for more than 5% of CO2 emissions, which are responsible for the increase in greenhouse effect. Research on that matter already testify the possibility of dosing concrete with lower binder levels, maintaining or even improving its mechanical performance. However, there are still no defined mix design methods for these materials that facilitate application in everyday life. Furthermore, there are few studies on durability assessment of these concretes, mainly as to their performance against the action of chlorides. Within this context, this paper presents a concrete mix design method with lower binder contents and evaluates its mechanical performance and durability. Using the principle of aggregate packing and optimization to control paste volume, concretes were elaborated with cement consumption of approximately 280 kg/m³ and 320 kg/m³. These concretes achieved compressive strength above 60 MPa at 28 days. The results indicate that concrete with lower binder consumption has lower content of voids and pores of smaller diameters, offering very high resistance to the penetration of chlorides. On the other hand, conventional concrete with cement consumption of 350 kg/m³ obtained low resistance to the penetration of these aggressive agents. To evaluate the performance against the action of chlorides in concrete with even lower cement consumption, a unidirectional chloride diffusion test was carried out in dosed and molded concretes in the Microstructure Laboratory of the University of São Paulo. The cement consumption of these concretes varied from 140 kg/m³ to 280 kg/m³. For lower cement content, due to very high amounts of incorporated filers it was necessary to use a higher water-cement ratio, which may have caused an increase in porosity and loss of performance as the resistance to chloride penetration. Overall, it is found that it is possible to reduce the amount of binder in the concretes and still improve its mechanical and durability performance. In order to achieve this, it is necessary to use new mix design methods that seek the maximum aggregate packaging and the paste optimization.

The study provides a comparative discussion between the analytical aspects of treatment and meaning of the Public Services International (PSI) and the contributions of Boterf Le (2003) regarding the parameters of competence as a potential present and needed the job and/or Tour Working in the Public Sector as well as element in evaluating the value of a compensation system. The work is divided into five chapters covering theoretical discussions related to the concept of competence, remuneration in the Public Service, gender equity and gift ideas on the concept of professionalism. It was also the evaluation of positions at the municipal level as a method of designing the pay system. Aimed to broadly examine the composition of the factor defined in Skills Assessment Model Workstations proposed by PSI, in view of its suitability for the system of remuneration of the public service in Brazil, based on the Job and Career Plan of Education of the City of Quixadá (CE). Methodological procedures were established as quantitative and qualitatively in order to support the review of the literature, the single case study concerning the evaluation process made by the Committee Bipartite Equity Compensation (municipal government and union), as well as field research. The application forms interview took place on the server side of the Municipal Department of Education, occupants of 8 (eight) positions effective administrative agent, assistant general services, municipal guard, conductor, driver, teacher education (high school and higher) and supervisor of education. He is the focus on the level of agreement of occupants in relation to the score received by his office in each sub-factor (education and experience, analysis and reasoning abilities, interpersonal skills and physical prowess) Skills Factor Model ISP. The research demonstrated the applicability of the evaluation of jobs in municipal government, as well as realizing that professionalism can provide theoretical support to the discussion of structure in the Public Service positions. They point to research as a restriction lawlessness municipal salary structure defined from the results obtained by scoring positions. Future work may involve other factors besides posts evaluative skills, such as effort, responsibility and working conditions.

One of the most relevant factors for the appropriate behavior of a welded component when in service is its thermal history, given the high heat input involved in joining the parts as well as the defects related to the inadequate adjustment of the welding parameters. One of the most common practices to produce high-quality welds, with greater efficiency, is the execution of weaving movements during the process, because they provide a wider weld bead, the proper fusion of the joint edges, and other benefits. Although numerical methods, such as the Finite Element Method – FEM –, are widely used in the simulation of welding processes, the mathematical models of heat sources representing the electric arc action in the welded piece do not cover the weaving motion, and adaptations regarding the mathematical description of the heating during welding are therefore necessary. In this context, the present study proposes the incorporation of the weaving movement in welding simulation based on the parameterization of the path traveled by the heat source during the execution of the movement, with the establishment of two case studies, in which one establishes a comparison between the proposed method and the coordinate transformation method, the most commonly used technique, based on numerical and experimental data from the literature, as well as the realization of an experimental analysis to observe the thermal cycle in points of a welded plate. The results showed that, although it is a simpler method than the coordinate transformation one, the path parameterization is capable of accurately representing the weaving movement in welding simulations, thus providing relevant information regarding the temperature distribution and the thermal cycle of welding.

Forensic samples from cases of sexual crime are often characterized by an unbalanced mixture between the victim's epithelial cells and sperm cells of the offender. DNA extraction by organic differential lysis is still the methodology routinely used to process the separation of male and female DNA in these samples, based on the resistance of the nuclear membrane of the sperm cells to certain reagents. However the technique is extremely time consuming and uses toxic organic solvents such as phenol and chloroform and modifications in this protocol has been a challenge for the forensic laboratories in the world. This study propose the use of DNA extraction kit DNA IQ™ System (Promega) with magnetic particles to eliminate some drawbacks of the standard technique. To perform a comparative analysis between the current use technique and the proposed, 50 samples of sexual crimes were submitted to the same analysis conditions by the two methodologies, resulting in 100 extraction products non-sperm fraction (NSF) and 100 sperm fraction (SF) results. Samples were quantified by real-time PCR using the Plexor HY® System kit (Promega) to evaluate the quantity and quality of amplified autosomal and Y chromosome DNA. 86% of the sperm fractions (SF) from the extraction using the DNA IQ™ System kit presented higher amount of amplified DNA autosomal compared to the standard differential extraction. With respect to Y chromosome DNA, 66% of the samples extracted using the commercial kit technique offered higher amounts of amplified DNA as compared to the standard technique. Statistical analyzes were performed using GraphPad Prism® v.6.0 software and the Wilcoxon test showed that the differences were considered statistically significant with p < 0.0001. The research demonstrated that the technique using the DNA IQ™ System kit is more efficient than the organic differential technique in all analyzed parameters, providing the elimination of toxic solvents, guaranteeing greater security for the forensic analyst, faster execution of the extraction and favorable quantity and quality of recovered DNA. Therefore, its implementation is indicated as an alternative method in forensic laboratories to analyze samples of sexual crime.

Terrestrial isopods (Crustacea, Oniscidea) constitute the most successful group among the crustaceans that colonized the terrestrial environment. Actually, there are about 3,700 known species. Only three proposals, directly and indirectly, sought to understand the evolutionary patterns within Crinocheta (a monophyletic group of Oniscidea with approximately 2,750 species). The results of these proposals were inconclusive, leading the authors to assume that the phylogenetic relationships presented are weakly supported. It was intended to refine and seek new evolutionary evidence for the phylogenetic relationships in Crinocheta, evaluating the phylogenies already proposed in the literature. All available taxonomic literature was used referring to the taxa of Oniscidea and related subjects, mainly for Crincoheta. Pictorial cards were constructed for comparative analysis of the illustrated structures. From this process it was possible to see some structures that were tried to place within an evolutionary context along with the taxa that hold these characters. Initially it was concluded that there are few groups in Crinocheta that are strongly supported monophyletic units. The families are mostly paraphyletic groups, this being one of the main problems to use this taxonomic level as terminal taxa of the phylogenetic analyzes already published. Therefore, this work is the beginning of a laborious research that intends to propose consistent monophyletic groups for the Crinocheta lineage. Failure to follow the procedures normally used for cladistic analysis is due to the fact that previous attempts have not been very successful in their results.

"The advent of Quantum Mechanics brought a new understanding of the world and new perspectives of technology, such as methods of optimization and alternatives to classical electronics. Recently an alternative has been sought for conventional electronics based on the electric current, this electronics would be based on spin propagations, and therefore we call it spintronics. In view of this perspective, the study of spin waves and magnetic phenomena in solid state physics is of paramount importance. Therefore, we have studied Magnons from the quantum Hall effect and sought the dynamics of these quasi particles subjected to a topological defect. In this work we will review the Aharonov-Bohm and Aharonov-Casher Effect to understand the quantum phases as geometric phases. We will study the Berry phase as the result of an external influence and Berry’s curvature to then verify the occurrence of the Quantum Hall effect. We sought the quantization of Landau for neutral particles with magnetic and electric dipole moment subjected to external electromagnetic fields. We sought to conceptualize magnons as collective low energy excitations and look for the occurrence of Hall Effect for them through the quantization of the Transverse Hall conductance. We also look for the Thermal Hall conductance due to a temperature gradient and thus the thermomagnetic ratio, we observe that such a reason follows Wiedemann-Franz’s law. We also review the Landau quantization for a neutral particle with a magnetic dipole moment and subjected to a topological defect of the cosmic string type and verify that the presence of the defect breaks the infinite degeneration of the Landau levels. In this work we consider the Hamiltonian proposed by Bakke, Ribeiro, Furtado and Nascimento (2009) [25] as the effective hamiltonian of the magnons in the presence of topological defect of the type cosmic string and we find the levels of Landau for the system. With this, it was possible to find preliminary results of Hall and Hall Thermal conductance of magnons in the curved space of the cosmic string at the non-relativistic and low temperature limits. Studying the properties of a network of magnons this work also seeks to instigate research that seeks to understand the behavior of the properties of these quasi-particles subjected to topological defects of various types and thus contribute to a better understanding of the dynamics of magnons and their properties."
