The aim of the present study is to investigate the relations between the concepts of actual and virtual in the philosophies of Henri Bergson (1859-1941) and Gilles Deleuze (1925-1995). We, therefore, make a systematic comparison of the two authors‟ conceptions of temporality based on the three synthesis of time proposed by Deleuze in Difference and Repetition. First, we develop the idea of the living-present in both authors, which is defined as a profound present, i. e. a present equipped with a multitude of degrees or levels of duration through which the immanent relationship between consciousness, body and the material universe takes place. What Bergson and Deleuze call actual is basically the living-present. Afterwards, we study the past in both authors, in order to show that, according to them, our entire past experience is never actually lost, but remains somehow lodged in our immediate consciousness (Bergson) or is stored in a large ontological memory (Deleuze). What Bergson and Deleuze call virtual is constituted by this domain of the past (although Bergson, in contrast to Deleuze, never employs this term as a substantive). After presenting the two authors‟ conceptions of present and past, our aim is to show how they conceived the relationship between actual, virtual and thought. In Matter and memory, Bergson outlines a true theory of knowledge from his theory of actualization of pure remembrance, while in Difference and repetition, Deleuze suggests a complex theory of Idea and thought from his conception about the virtual. However, before studying Deleuze‟s theory of Idea, we concentrate on his third and final synthesis of time – the synthesis of future. Our aim is to show how Deleuze uses it in order to deal with some difficulties resulting from Bergsonism, especially in reference to the possibility of production of the authentic newness, i. e. the creation of something that cannot be reduced neither to the possible nor the past.

The Food Acquisition Program (PAA), sanctioned by the Law number 10.696 of 2nd July, 2003, is one of the specific actions of the Zero Hunger Program, which aims to encourage the family farming, the access to food people in a situation of nutritional and food insecurity and the marketing networks. This study had the general objective to build a diagnosis of PAA in the county of Monteiro, in state of Paraiba in the period of 2011 to 2014, focusing on family farmers, organizations (associations and cooperatives) and institutions which participate in the program, in order to reveal important characteristics of social and economic issues and the consequences of public policy at the municipal level. To achieve the stated goal, the present study was conducted in qualitative and quantitative descriptive, made by an exploratory research, using secondary data SAGI Platform, semi-structured scripts with a recorder and questionnaire. Thus, we held interviews with the program executors (CONAB and county), coordinators of the institutions, nutritionist, presidents of organizations and family farmers. With data and analysis, it was possible to identify positive and negative effects of the program, among the positives are: strengthening organizations and safer production, increase in nominal income, financial independence, increased purchasing power, market insertion and improvement in relations of confidence. The negative were: indebtedness of farmers, frustration, lack of motivation to participation, especially by farmers who developed beneficiation activities, and discontinuity of resources and donations to families in levels of food insecurity. From these findings, It is concluded that the program leveraged organizations and provide an improvement in the socioeconomic conditions of family farmers, however, must occur in the restructuring of the program, given that the limitations directly affect everyone involved.

The objective of this study was to analyze the development of communicative actions in a child with congenital deafblindness after the Cochlear Implant (CI). The study took place in an inclusive public school with Service Center specializes in the area of Deafblind. Research it is a case study of a child with congenital deafblindness full, ie without hearing or visual residue and at eight was submitted to the IC. The child started the service in this center in 2011 and in 2013 passed the CI surgery, so in 2014 the device was activated, causing there was the possibility of communication using a sensory pathway. Data collection initially consisted of desk research in the records of the initial calls before the IC, then there was the interview with the mother, caregiver and teacher. still consisted with initial assessment through data collected in documentary research and final evaluation after the IC. To collect data after the IC, there were three weekly sessions lasting 3 hours, the comments were in attendance in activities such as reception, food, auditory stimulus and orientation and mobility. The data obtained were analyzed qualitatively according to the table of communicative competence levels, according to Rowland & Stremel-Campbell, adapted by Cambruzzi, considering them as a criterion for measuring the development of the child's communicative actions. The results showed progress in language acquisition, ie, the child presented intentional efficient communication using reference objects to express their desires and communicative actions to others. The family found itself without the support of a specialist that offers support to foster the process of communicative actions in their home environment. The results show a gradual development of communication levels after IC. However, it was noted that the presence of a qualified professional in the field of deafblindness paying attention not only the child is necessary, but family support for the success of communicative actions actually happen.

Este trabajo pretende ofrecer una lectura de la novela Niebla (1914), de Miguel de Unamuno, a partir de algunas de las formulaciones de Mijail Bajtin, en Problemas de la Poética de Dostoievski, sobre la carnavalización literaria. La aproximación de la novela de Unamuno con la teoría de Bajtin se justifica, puesto que se pude notar -- tanto en Niebla como en las formulaciones de Bajtin -, el carácter crítico de la subversión de la norma literaria a través del llamado “sério-cómico”. Para ello, se presentan algunos aspectos de lo cómico en Niebla, que se encuentran imbricados, en cierta medida, en las ideas filosóficas del autor. En la sequencia, se presenta una lectura de algunos aspectos de la carnavalización literaria en Niebla, oriundos del campo “serio-cómico”, que confirman el carácter innovador de la novela en una época en que todavía la convención realista era bastante fuerte en España.

Model-Driven Development (MDD) is proposed to reduce the semantic gap between problem and solution/implementation domains. Some tools are used, and the code generator is commonly used in this context. These generators are often implemented using templates. A Reference Implementation (RI) favoring the development/ maintenance of software facilitates this implementation’s types. However, RI requires a code migration process which consists in artifacts’ synchronization, and it is responsible for 20% to 25% of the time spent on development. The literature has no describe automatic solutions, but the group that this reaserch was included has develop tools that automate this process and reduce the time spent on some tasks. But each task has a different performance in relation to time spent, so automation of some tasks can be disadvantageous. Few reports describe such tasks and which ones are capable of automatic code migration. The aim of this study is to investigate the maintain and evolution process to identify and describe the types of maintain and evolution tasks that are essentially. Based on this study, a method (MME-MDD) that drives the developer during that proccess to guide the developer during the realization of each task, with the aim to maximize the benefits of this approach. The MME-MDD was validated by a case study and a empirical study and the method showed effective in most of tasks. In addition, studies show that using the proposed method brought a gain in the quality of the source code.

By providing ever-growing processing capabilities, many database technologies have been becoming important support tools to enterprises and institutions. The need to include (and control) new data types to the existing database technologies has brought also new challenges and research areas, arising the spatial, temporal, and spatiotemporal databases. Besides that, new analytical capabilities were required facilitating the birth of the data warehouse technology and, once more, the need to include spatial or temporal data (or both) to it, thus originating the spatial, temporal, and spatio-temporal data warehouses. The queries used in each database type had also evolved, culminating in the STOLAP (Spatio Temporal OLAP) queries, which are composed of predicates dealing with conventional, spatial, and temporal data with the possibility of having their execution aided by specialized index structures. This work’s intention is to investigate how the execution of each predicate affects the performance of STOLAP queries by varying the used indexes, their execution order and the query’s selectivity. Bitmap Join Indexes will help in conventional predicate’s execution and in some portions of the temporal processing, which will also count with the use of SQL queries for some of the alternatives used in this research. The SB-index and HSB-index will aid the spatial processing while the STB-index will be used to process temporal and spatial predicates together. The expected result is an analysis of the best predicate order while running the queries also considering their selectivity. Another contribution of this work is the evolution of the HSB-index to a hierarchized version called HSTB-index, which should complement the execution options.

In the present work, Layer-by-Layer films of Anti-PSA antibody in the absence and presence of DPPG liposomes were produced in order to study the detection of prostate specific antigen (PSA) by different characterization techniques. The free Anti-PSA antibody in solution and incorporated into liposome was characterized by UV-vis spectroscopy and Circular Dichroism (CD). In the first characterization, it was verified the main absorption bands of the antibody and a possible aggregation in the absence of the liposome. CD measurements indicated disordered structures of free antibody. However, its secondary structure (ß-Sheet) was maintained in the presence of liposomes. The film Layer- by-Layer of free Anti-PSA antibody and incorporated into DPPG liposomes was done alternating the antibody with different polycations, PAH (poly (allylamine hydrochloride)) and PEI (poly (ethyleneimine)). The films fabricate on quartz and gold sensors were characterized by UV-vis and SPR spectroscopy. These results proved the deposition of the materials on different substrates and the PEI was the best polyelectrolyte for immobilization of the antibody. Through the SPR measures it was simulated thickness and refractive index of the film bilayers. The PEI, PVS and Anti-PSA casting film and PEI/PVS and PEI/Anti-PSA LbL films were characterized by FTIR, it was observed through the bands of the spectra the interaction between the polyelectrolyte and found the deposition of antibody in the film. Acting as PSA detection unit, the (PEI/PVS)1/(PEI/Anti-PSA+DPPG)5 and (PEI/PVS)1/(PEI/Nati-PSA)5 films were characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and SPR and both systems were able to detect PSA at concentrations below 4 ng.mL-1 that is the normal concentration for a healthy individual.

Context: Operating in different contexts and segments, embedded systems (ESs) are increasingly present in everyday society. The ESs usually operate invisibly to the user but, even so, possible software failures cease to pose risks, causing serious material and financial damage. Taking into consideration the safety of users of ESs, government entities and institutions around the world have studied and created standards development and SEs test to ensure systems that are more robust and free from defects that may cause faults that may endanger the user. However, standards are usually applied at the level of code, which increases substantially the resources to be used if there are defects in the SE. Objective: To present the UL/ME Strategy that addresses the shortcomings described in SEs certification standard, UL 1998 level modeling, more specifically, in the model of Statechart states. The purpose is to anticipate the identification of defects, to generate code that has more chance to meet the standard requirements, preventing rework and therefore improving quality. Methodology: The study was conducted in three stages: first stage identified the defects treated by the standard UL 1998, tabulating these defects, and then, link them to the SEs components. In the second stage were designed generic models for each component and also the ESs models that represents the tests required by the standard for each components, and in the third step, it was created two proposed for use UL/ME Strategy, one for ESs already implemented and other for ESs in development. These proposals were used for evaluation of the strategy using two real ESs, one already implemented and other in development. Results: According to the requirements of UL 1998 standard, the use of Strategy UL/ME helped to correct the defects of the first ES and evaluated the development of the second ES. Conclusion: the use of Strategy UL/ME assisted in the correction of an SE already implemented and modeling of an ES in development.

The current use of the Internet differs greatly in relation to its initial design. Internet users are becoming interested in accessing and sharing content regardless of their physical location. For future Internet, information-centric networking is considered a potential solution to many of its current problems. Information-centric networking treats content as the main element in the architecture rather than the host location. Information-centric networking is intended in becoming Internet most efficient and safe, however, as it is still under development, it leaves open the solution to many privacy issues. The privacy concept may cover many different aspects and must be respected by applications. In this work the privacy is considered as the right of the user to control who can access your data. Thus, this work aims to propose a mechanism for applications in Information-centric networking that allow a publisher user to define which users can access their content. To ensure the content confidentiality and hence the user's privacy publisher, the proposed mechanism uses an attribute-based encryption technique, called CP-ABE, which allows the use of access policies that are defined and stored in the content. To enable the immediate revocation of privileges, it is inserted a proxy server that operates in the decryption process. As a proof of concept of the feasibility of the proposed mechanism, an application to share encrypted file was developed. The application adopts an access control policy that limits the decryption only by authorized users. This application was performed on a simulator of the Named-Data Networking architecture, called ndnSIM. Performance tests against major system functions have been performed in order to determine the feasibility and limitations of the mechanism. The tests analyzes the file size after encryption, processing time and RAM memory consumption. The tests concluded that the mechanism is viable in terms of performance.

The so-called "Plant Ecology Strategy Scheme" groups species into categories along the spectrum of their functional traits. When two or more important functional traits are correlated between concurrent species, they define a strategic dimension. There are four main dimensions of ecological strategies for establishing the relationships among functional traits of plants: maximum plant height, size of branches and leaves, leaf structure and physiology, and seed production. Traits that may define these dimensions include: maximum plant height, wood density, leaf area, specific leaf area, fruit size, and seed size. We analysed the relationships among the traits in cerrado woody species and compared the results with those found in tropical forests. In this dissertation, we presented our results in a single chapter, written in english. We measured these traits from 28 woody species at the Vaçununga State Park, southeastern Brazil. We found two significant relationships: between fruit size and seed size and between fruit size and leaf area. We also identified two ecological strategies: species with high specific leaf area and species with low specific leaf area. Cerrado and forest woody species seem to have distinct ecological strategies, probably due to the different environmental pressures to which they are submitted.

The Dyslexia field of study is marked by tensions and controversies about the possible causes of the difficulties of learning the written language made by children during literacy. The dominant thinking has understood dyslexia as a product of neurobiological disorders that affect the processing responsible for reading and writing. In contrast, critical researchers to this hegemony have stated that the acquisition of writing should be understood as a cultural process in which children exercise their subjectivity. Thus, errors made in writing should be understood as an exercise of this subjectivity and experience with this object of culture. Considering these aspects, this study aimed to analyze academic theses and dissertations developed during the period 2002-2014, in order to understand how the concept of dyslexia has been developed and what their implications for education . The assumed methodology was a literature review. Theses and dissertations analyzed were raised in the pages of CAPES and BDTD. The survey pointed to 72 research. To better meet the proposed goal, this research was divided into two studies. In Study 1, which were analyzed all the research raised under the chronological distribution categories, region of the country, administrative category, Community College, Graduate Programs, Search Types, Research Subjects, theoretical approaches and dyslexia conceptions and findings and conclusions of the studies analyzed. The considerations of this study show that the hegemony of scientific thought which defines dyslexia as a neurobiological disorder may be hindering the development of new insights into the phenomenon and also crystallizing the concept of disabling condition, which follows the opposite of proposals for inclusive education. In Study 2, only we analyzed the research developed in the field of study of education in the following categories: type of study and research methodology, dyslexia conceptions of learning, on the acquisition and development of reading, teaching, education, and what are their contributions to school practices. The considerations of this study show the same dominance of present scientific thinking on the analysis by the Study 1, added to an excessive concern with the diagnosis and considerable uncertainty about the way they are the written language learning processes. The Final remarks raised concern over the proposed school model and the way may be implying about individuals.

We report a systematic study on the structural, morphological and optical properties of Zn1−xCoxO thin films grown by spray pyrolysis. The employed nominal concentrations were up to 15 Co %. The films were deposited on glass substrates between 220-300 o C using precursors such as zinc acetate and cobalt acetate in aqueous solutions. The effects of Co-doping on structural, morphological and optical properties were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), optical transmittance and absorbance as well as photoluminescence (PL). The XRD results indicated that all films are polycrystalline with wurtzite crystal structure, a preferential growth direction in c-axis, and no secondary phases. SEM images generally showed uniform surface, and few regions have irregularities due to effects of the inclusion of cobalt as well as substrate deposition temperature. The spectra of transmittance and absorbance exhibited the transitions d-d due to Co2+ ion, a redshift of the absorption-edge and changes in the absorption band intensity with increasing of nominal Co-doping. These observations revealed the substitution of Zn ions Zn2+ and the presence of Co in the state 2+ in tetrahedral coordination in the ZnO lattice. Furthermore, there was a narrowing in band gap of 28 meV by percentage of Co inserted into the lattice. The PL spectra of ZnCoO samples presented three bands associated to near-band-edge absorption (NBE), structural defects and intratomic emissions of Co2+. Their optical emissions were characterized by the presence of traps which capture carriers and affect significantly the emissions. Through a qualitative model in a temperature range we interpreted these traps as potential fluctuations up to 17 meV. We also discussed the annealing in selected samples.

This study examined the ecomorphological pattern ofichthyofauna in two watersheds located on the Upper Paraná River. It was analyzed the ecomorphological variations of species collected from the Beija-Flor stream and Beija-Flor reservoir located in Estação Ecológica de Jataí and Lapa stream located in Área de Proteção Ambiental Corumbataí/Botucatu/Tejubá, to verify interspecific morphological differentiation, the effects oftrophic guilds along the ecomorphological patterns and the effects of water velocity along the ecomorphological standards. Of individuals collected in Estação Ecológica de Jataí, it was selected two Characidium species, on which the ecomorphological variations related to possibility of inter specific morphological differentiation of species of the same genus were analyzed. Considering the common species between the Estação Ecológica de Jataí and the Lapa Stream were observed morphological variables in order to verify the intraspecific morphological differences. Finally these results were related to the meaningof the relation ship between form and function. The main morphological differences found in the individuals of this study were related to the speed of water and feeding habits of the species. The distribution of species in morphological space showed the relation between the ecomorphological attributes and the distribution of species over the water column, where it was possible to characterize the species as demersal, nectobenthicand nektonic species. The relation ship of fish morphology with the water velocity is fundamental. The feeding also contributes with smaller importance in the separation of species in ecomorphological space, but this contribution seems to be because of the presence of these food items is also influenced by the speed of the water. The function of the species in the environmentin which they liveis linked mainly to its trophicniche.

Agriculture, urbanization and industrialization are some of the human activities that are constantly generating negative impacts on the environment. Much of this degradation directly affects exhaustible lotic systems that are important sources of water supply for the population. This provides the aggravation of problems in obtaining clean water. From this context, the present study aims to assess visual characteristics of habitats in the longitudinal gradient of Araras River and along with the seasonal monitoring of physical and chemical parameters of water quality, state of the natural environment conservation status, while characterizing the changes caused by anthropic activity. For the survey data, 6 points of evaluation were select, ranging from stretches of rural and urban areas. The evaluation took place using the Rapid Assessment Protocol of Habitat Diversity, which at the end of the application, defines the environment preservation level. The monitoring with collection of water samples complied with the climate (drought, intermediate and wet), totaling 13 parameters measured, submitted to analysis of simple variance (ANOVA), using as multiple comparisons test the Tukey test at 5% level of significance. Both, the results of water quality analysis and the PARs analysis showed degradation of shares in the Ribeirão das Araras, as a result of human activities. Regarding seasonality, there was a significant difference only between the parameters: total nitrogen, total phosphorus, chloride, sulfate and electrical conductivity, but without apparent climate relationship. Total phosphorus parameter, except for the 3rd poit, showed values above the limit, established by CONAMA, in the Resolution 357/05, with higher concentrations in the dry season. However, in the 5th point, it was highlighted by having higher concentrations in almost all parameters and also by disagreement in turbidity parameter in the interim period. The protocol described the whole gradient evaluated as amended (48.6 points). The points of greatest environmental criticality were the points 4 and 5, both classified as impacted. Together the tools showed that the points located in the urban area (4 and 5), are the most affected by human activities, mainly because of the margins occupation, channeling, rectification, removal of riparian vegetation, domestic sewage disposal, garbage on the banks, erosion, etc. So, the low-cost of tools adopted here, Ecokit and RAPs, provided to be an efficient way to evaluate the water resources.

Brazil plays an important role in the consumption and production of ceramic tiles nowadays. The decoration of tiles by digital inkjet printing, due to its technical and aesthetic advantages, is a spreading technology and has already been adopted in the national industry. Ink sets acquired from different manufacturers differ in their extension behavior on the ceramic surface, in the definition of the printed pattern, in the range of printable colors, and in the ink yield, square meters of a same decoration that can be printed for unit volume of ink. Due to the peculiarities of this technology, there is still no methodology for evaluating the performance of the inks and there is very little published on this topic. This paper proposes a methodology for a comparative evaluation of the performance of industrial inks, aiming to help in the selection of these inputs by ceramic tiles producers. Drops of the evaluated inks were applied on a defined ceramic substrate. The colorimetric behavior and the extension of the ink were assessed as indicative parameters of the image quality and yield of the inks. The colorimetric characteristics and the size of the points produced with inks from different suppliers were significantly different for all the four colors of the inks evaluated. For all these colors, the results point to similar conclusions, demonstrating the validity of the method. Some technical characteristics of the inks were studied to identify the reasons for the different behaviors observed. The color differences between inks of different suppliers are explained by the different pigment phases in each composition of ink. The extension of the inks were greatly influenced by its viscosities. The more viscous inks, due to greater difficulty in penetrating the ceramic substrate, expanded more over it.

Esta investigación científica tuvo por objetivo general verificar como un proyecto de letramento que prioriza la cultura indígena como eje articulador pudo contribuir para el desarrollo de la escritura de los niños de manera significativa. Por consiguiente, el trabajo se justifica y tiene relevancia a medida que apunta posibilidades de colaboración para el reconocimiento de la diversidad cultural brasilera y del indígena, en el ambiente escolar, al mismo tiempo en que se preocupa por el desarrollo de la escritura de los alumnos, utilizándose de la dinámica de los proyectos de letramento. En beneficio de eso el embasamiento teórico del trabajo permeó, principalmente, la Psicología histórico-cultural de Vygotsky (2012), la Teoría de la Actividad de Leontiev (2012), la propuesta de proyecto de letramento de Kleiman (2007; 2009), y las reflexiones tomadas en los cuadernos del Pacto Nacional por la Alfabetización en la Edad Cierta (PNAIC) y en el grupo LEETRA, que presenta fuerte investigación científica relacionada a cuestiones indígenas. En lo que dice respecto a la metodología, la investigación es colaborativa y sigue el paradigma cualitativo-interpretativo, además de desarrollarse como un estudio de caso. Utilizamos herramientas como diario de campo, dibujos, fotografías y grabaciones de audio para fines de registrar los datos de nuestra investigación. Mediante el análisis de los datos generados, los resultados evidenciaran que el proyecto de letramento contribuye para el desarrollo de la escritura de los niños al preocuparse con la inserción de los alumnos en prácticas sociales de uso de la escritura, en conformidad con la participación activa de los alumnos en el proceso de aprendizaje. Aún dentro de tal dinámica pedagógica del trabajo con diversos géneros textuales es valorado lo que favoreció el desarrollo de las competencias linguísticas de los estudiantes al permitir al niño tener consciencia de su propia actividad como usuario de la lengua. Los datos demuestran también la posibilidad de pensar en el reconocimiento social del indígena, levando para la sala de clase informaciones a respecto de diferentes costumbres de grupos étnicos brasileños, enfatizando el multiculturalismo existente en nuestro país.

Residuals play an important role in checking model adequacy and in the identi cation of outliers and in uential observations. In this paper, we studied two class of residuals for the zero adjusted gamma regression model (ZAGA) and the zero adjusted inverse Gaussian regression model (ZAIG). These classes of residuals are function of a residual for the continuous component of the model and the maximum likelihood estimate of the probability of the observation assuming the zero value. Monte Carlo simulation studies are performed to examine the properties of this class of residuals in both models (ZAGA and ZAIG). Results showed that a residual of one of these class has some similar properties to the standard normal distribution in the studied models. We also described ZAGA and ZAIG regression models, studied properties of some residuals in generalized linear models with response gamma and inverse Gaussian and discussed other aspects of diagnostic analysis in ZAGA and ZAIG models. To nsih, we presented a real dataset application from investment funds of Brazil. We tted the ZAIG model to illustrate the topics discussed and showed the importance of these models and the advantages of one of the studied residuals in the analysis of real dataset.

We present a discussion about teaching practices, through the organization of courses and the structure of the curriculum, where the formalistic and Cartesian conception of mathematics is incorporated into the teaching of science, used not only as scientific language, but as a model for knowledge organization. The presence of the practice in the classroom is shy and most often used for justification, not for discovery. The overvaluation of the essence of the theories at the expense of its practical effects can ward off the interest of learners and result in the low scientific literacy that we observe the end of the education process. We intend to explore ways of alternative thoughts them the formalist one, and educational practice oriented for challenges, curiosity and discovery.
