The use of computer virtualization has grown rapidly in recent years, motivating the research for software and hardware improvements to optimize performance and reduce the bottlenecks inherent of virtualization. In the middle of this decade, the processors has added support for CPU virtualization, simplifying the design of virtual machine monitors, but the employed approach had performance limitations when combined with the virtualization of memory using shadow page tables. Adding support for nested paging hardware was the answer to this problem, providing performance closer to the native, ie, without the virtual abstraction. The multicore processors were the solution to keep the microprocessors' performance growth , as the monolithic architectures were close to their limit. The use of virtualization allows exploiting parallelism offered by them through the simultaneous execution of multiple virtual machines. This study evaluates the virtualization of memory subsystem and its interaction with the multicore architectures, to determine the set of features that maximize performance. We evaluated shadow and nested paging, comparing the use of conventional and large pages to map virtualized memory. We also analyzed the influence due to the presence of a level of cache shared among cores. The results showed that in the evaluated scenario the best performance was achieved by using nested paging using large pages to map memory, while the additional level of cache didn't bring any specific benefits to virtualization.

This study evaluated the influence of the upflow velocity in anaerobic fluidized bed reactor to produce hydrogen. In order to compare that effect, four reactors were used under different upflow velocities each: 0.30; 0.60; 1.24 and 1.88 cm.s-1. Expanded clay was used as support material for immobilization. A synthetic wastewater containing glucose (5000 mg.L-1) was used as substrate. Reactor R124 that was operated under minimum fluidization velocity (1.24 cm.s-1) showed the best values for hydrogen production. The maximum hydrogen production rate was found to be 1.22 L.h-1.L-1. The maximum hydrogen yield was 2.55 mol H2 mol-1 glucose and the biogas content ranged between 30,5 and 61,8 %. No methane was generated. The optimum TDH for expanded bed reactors was 1h while in fluidized bed reactors were 2h. Ethanol was the main metabolite produced, suggesting an ethanol-type fermentation. No trends were shown regardless of the upflow velocity imposed to the system. However, the higher the velocity applied, the higher the hydrogen production rate.

This Project starts from an observation and a questioning: why haven t Cândido Portinari s works - greatest Brazilian painter and born in the state of São Paulo -, been taken into account by the Curricular Proposal of the State of São Paulo regarding the Arts teaching books, in particular the visual ones? Doesn t his work have any importance for the country? Don t the elaborators of the mentioned proposal know him? From the analysis of this material, a research has been done with the survey of bibliographies about the painter that could reveal his life, not only the one already known of the general public, but the one that could serve as a basis to teachers that teach art in public schools of the state of São Paulo. Through this investigation, we try to show someone worried about his people, an educator made by the image and a man formed by the observation of his work. The first chapter reveals us Portinari s formation, his family, religiosity, his involvement with Communism, his friends, his stay in Europe, his moving to Rio and his occasional trips to Brodósqui; besides the awards received, his escape of school and the greatness of his work. The second chapter shows the reader all the educational features of this painter, his concerns about the future of education in the country and mainly about the simple man who has been building this nation and not revealed by our old masters. Which man does Portinari show in his works? The third chapter compares and analyzes contemporaneous artists works taken into account by the Curricular Proposal of the State of São Paulo. It inquires about the presence of these education icons and reflects/questions Cândido Portinari s absence.

Citrus canker is an economically important disease that affects many citrus growing areas around the world, and there is no effective control or cure. The causative agents are bacteria from the genus Xanthomonas, recently classified as two novel species, X. citri e X. fuscans. The most virulent strain is X. citri subsp. citri (Xac). In this study, we did a differential proteomic analysis of a periplasmatic proteins enriched fraction from Xac, by comparison of the protein profiles after cellular growth in pathogenicity inducing medium (XAM1) or non-inducing medium (Nutrient Broth). We performed Bidimensional Electrophoresis (2D-PAGE) in triplicate and statistical analyses were done with the software Image Master Platinum (GE). At least 80 spots showed significant differences on protein expression (p<0.05) between the two conditions tested (induction/ non-induction) and had their proteins digested by trypsin. The peptides were analyzed by mass spectrometry (LCESI- Q-Tof) and the results were compared with proteins from genome databases using the Mascot tool. Among Xac proteins identified with higher expression in in vitro pathogenicity inducing situation, two are classified as proteins involved with Pathogenicity, Virulence, and Adaptation (in according to the genome annotation): superoxidase dismutase (XAC2386) e phosphoglucomutase (XAC3579). A highly differential spot (46), increased in the inducing condition, had their proteins identified as lytic murein transglycosilase (XACb0007) and/or transglycosylase (XAC3225), oxidoreductase (XAC1160) and DNA polymerase III subunit beta (XAC0002). The spot 46 was isolated from several 2D gels and used to produce antibody in mouse. The expressions of these proteins were analyzed by Western blot in others citrus canker genome strains, which differ from Xac in the virulence and host types. This analysis showed that proteins from the spot 46 had different expression pattern among these strains, with higher expression in Xac growing in inducing condition. We conclude that the proteomic study of proteins from periplasmic fraction is an important strategy to detect Xac proteins involved with pathogenicity and virulence, even including proteins transported outside the cell. Proteins found in this fraction could be used as biomarkers, however more experiments are still necessary.

Several synthesis methods reported in the literature have been developed to the formation of barium tungstate (BaWO4) powders, among these techniques; the microwave-assisted hydrothermal (MH) systems have offered important advantages in the coast reduction and/or formation of crystalline powders. The interest in the tungstates is because of its blue or green luminescence emissions at room temperature, which are able to favor the development of new electro-optic devices. The morphologies and particle sizes of these materials have been controlled by the use of surfactants and/or polymeric agents into the reaction medium. Therefore, the present work reports on the synthesis and MH processing of BaWO4 powders in the presence of ethylene glycol and polyvinylpyrrolidone at different concentrations. Thus, it was verified the influence of these surfactants in the morphology and growth process of the particles as well as its optical properties. The BaWO4 powders were synthesized by the co-precipitation method and processed in MH system at 140 °C for 30 min. These powders were characterized by X-ray diffraction (XRD), Fourier transform Raman (FT-Raman) and Fourier transform infrared (FT-IR) spectroscopies, ultraviolet-visible (UV-vis) absorption spectroscopy photoluminescence (PL) measurements and field-emission gun scanning electron microscopy (FEG-SEM). XRD results indicated that all materials have a scheelitetype tetragonal structure. The characteristic symmetric and anti-symmetric stretching modes of (WO4) groups were detected by the FT-Raman and FT-IR spectroscopies. FEG-SEM micrographs revealed the existence of micro-octahedra with different sizes and well-agglomerated. The optical band gap results suggested the presence of distinct types of structural defects, probably due to the synthesis or MH processing conditions. It was observed PL emissions in the blue and green region of the visible electromagnetic spectrum for the BaWO4 powders when excited with 350 nm wavelength.

This work has as study object the evaluation processes for higher education practiced in Brazil, and it tries to investigate if they have produced some improvement in IES and in degree courses. We consider important to understand the historical context that led to the creation of the first higher education courses in Brazil, the late institutionalization of the first university and the higher education s development in the country along the 20th century. The bibliographical revision about that period was important to understand the IES types that were created and the great expansion of the private sector, for the detriment of the public sector. The brief historical survey about evaluation showed the changes this practice had suffered until it started being used as a justification for public policies implanted to improve education s quality. To analyze the evaluation processes, we also made interviews with professionals who have participated for several years in internal and external evaluation processes in IES. The development of the first evaluation instruments, such as PARU, CNRES, GERES and PAIUB, occurred at the time when structural reforms were introduced in Brazil, aligning the country to the international agencies proposals, adopting the concept of Evaluator State. Critics have been made to the process of the reforms consolidation, which gave privileges to the private sector, boosting its great expansion. FHC s administration created ENC, known as Provão, whose results were used by media to make rankings with institutions and courses. With Lula as president, some intellectuals who were part of his government tried to do some changes and created SINAES, whose initial objective was to evaluate IES as a whole, considering ten dimensions. It was not difficult to notice this instrument suffered transformations and it retook the practice of ranking courses and institutions. We concluded that the evaluation promoted some improvement in IES and courses, especially due to the concern about being well placed in rankings. In spite of all the contradictions, we understand that the evaluation processes are necessary because of precarious conditions of many IES and courses that do not reach the minimum pattern of quality defined by MEC.

The present work describes a qualitative research on the training of teachers of English Language (henceforth EL) who deals with the Elementary School I. Initially, we intend to develop a historical background on the Postmodern Society on multicultural context. For this, there will be a brief history on the socio-cultural context of the child that is inserted in this society. After that, we will point to the importance of teaching foreign language for Children (hereinafter LEC), ie, the current reasons that have led to increasing numbers of children learning a foreign language (FL). Moreover, will be explicit the literacy teacher's LEC, in which the focus will be turned to the professional who teaches English classes in early grades. This route will remain to the desired skills that are expected from educators. Results of previous studies (Rocha, 2006; Santos, 2005) about teaching English to children point to the need to investigate more closely the skills of this professional, licensed by Modern Languages and Literatures programs. However, despite a degree in English during the graduation, the teacher receives the training to work only with elementary school students II. Moreover, the professionals of Education - enabled to work with children of elementary school I - are not trained in their graduation to teach foreign languages. Thus, both professionals - educated in Modern Languages and Literatures and Pedagogy - appear to be defective as regards their competence to teach English Language to children from 1st to 5th year. Thus, it was deemed important to monitor the work of three professors of LEC (English) in order to 1) identify the profile of the teacher who works with the teaching of English in the early grades, and, 2) investigate the process of teaching learning of Foreign Languages in Elementary School regarding the approach of the teacher who acts in this area. For data collection were selected two schools, one of the municipal and the other a private school had in it program the teaching of English for children from 1st to 5th year. In these schools, were investigated the work of three teachers, one educator and two graduates of Arts - Portuguese / English. Four instruments were used for data collection: observation of tuition through video recordings and audio, quizzes (with teachers) and interviews (with the coordinator and the teachers), to obtain data regarding the preparation of educators, as well as the goal pursued by the school to implement the teaching of English. Furthermore, were recorded daily research, aiming for better monitoring and observation of classes. Later there was a triangulation of data, which related to the literature, form the basis for the delivery of research.

In this work the magnetic properties of iridium oxide synthesized via Pechini s method and doped with different concentrations of cobalt were studied. The proposal was to investigate the possibility of applying it as a diluted magnetic oxide (DMO1). The samples were characterized by x-ray diffraction to study the structural features by Rietveld refinement, which indicated that there is no inconsistency between the observed intensities and the calculated profile. The samples were characterized by magnetization measurements as a function of temperature and applied magnetic field. A paramagnetic behavior was observed in samples doped with low Co concentrations. However, a small change in the magnetism appears in samples with concentrations up to 10 mol% of Co. A new metamagnetic phase was observed for samples with 25% and 30% in mol of Co.

The genus Anastrepha which is endemic to the Neotropical region has big economic importance to cause great losses in fruit production. We studied three species of the cryptic group fraterculus: Anastrepha fraterculus, A. obliqua and A. sororcula. Although no single marker is able to distinguish these species, some morphological and behavioral markers are able to distinguish them. There is evidence that these markers do not match the patterns of genetic variation and divergence of these flies. We investigated the role of genes related or not to reproduction in the speciation of these flies. We used a cDNA library of the reproductive tissues of females of A. fraterculus, to isolate expressed genes from those tissues. From a framework of divergence population genetics, we estimated relevant demographic parameters that reported the genetic architecture of speciation in this group. To study the separation of these species, we used gene trees as a framework to be compared and to infer eventual species trees. We amplified 12 genes isolated from the cDNA library. The analysis of population divergence and levels of polymorphism were made in DNAsp and showed high levels of polymorphism for the vast majority of loci. Neutrality tests reveal that only Fs Fu was significantly negative for the combination of species here considered. These results indicate a possible evidence of population expansion on this group of species. These data were corroborated by the values of ancestral and current theta estimated from the analysis undertaken on the software IMa2 program. These analysis also showed relevant levels of migration in some contrasts, but particularly among species which are more distant in the tree from the other two. However, the same analyses performed amongst species pairs fail to reveal high levels of migration rate among species, though t e theta values were close to those estimated in the analysis with all three species together. We also tested for the presence of selection at different loci, using the program PAML and obtained evidence of positive selection for three genes CG7203, CG8064 and MLC, whereas the gene CG7009 showed evolution by a mild purifying selection. The haplotype networks showed the grouping of haplotypes of the species for five of the 12 genes CG7009, CG8064, Elp, TCTP and Cyclophylin. CG7009 revealed possible species specific markers for A. sororcula. We carried out the deep coalescence analysis in the program MESQUITE, comparing gene trees simulated with real trees for each gene locus, placing the species as an outgroup for each tree model and obtained significant results, which would be compatible to simulated scenarios only for the genes V Cyclophylin and TCTP. The tree obtained by minimizing the deep coalescence estimated showed that A. sororcula is farther from the other two species of the genus Anastrepha. It is necessary, however, a larger investigation of different genes, particularly genes with higher evolutionary rates and an expansion of the samples of these species to consider geographical distribution and assist in studies of speciation of this group.

O artigo propõe uma avaliação da política educacional implementada pelo primeiro governo do Partido dos Trabalhadores no município de São Carlos (SP), entre 2001 e 2004. Nesse período, o panorama educacional brasileiro já estava marcado, desde a ditadura militar (1964-1985), por uma ampla gama de experiências e reformas, as quais tiveram como um de seus resultados mais importantes a universalização do acesso à escolaridade obrigatória já no final da década de 90. Resolvida a questão quantitativa, o grande problema a ser enfrentado passou a ser o da qualidade do ensino ofertado na escola pública. Apesar da situação privilegiada da cidade de São Carlos, situada numa das regiões economicamente mais ricas do país e com forte tradição educacional, nossas pesquisas nos levam a afirmar que a primeira gestão petista do município deveria ter materializado uma política educacional mais efetiva do que aquela implementada, a fim de atingir a melhoria da qualidade do ensino ofertado à população.

This research was based on the need of understanding the presence of black children in the 19th century and as a consequence understand childhood from this perspective. It intended to show how black children could be seen through images produced in the 19th century, which were selected from a corpus of engravings by Jean-Baptiste Debret and portraits by Militão Augusto de Azevedo. To discuss how the black children were represented in the images we tried to establish a relation between the history of children and childhood in Brazil, as well as to point out the importance of the image to the comprehension of the historical construction of the Brazilian black childhood framework. The analysis was based on a Foucaultian perspective, in which we aimed at focusing not on what the images hid, but at what these images showed as possibilities for these children and for black childhood as a whole in the 19th century. In addition, we analyzed the literature concerning slavery to understand childhood slavery presented in the famous works of Debret. We also searched other images that revealed different aspects of black childhood. This effort allowed the selection of portraits made by Militão, a gallery of unknown people, which showed black children quite differently from the first images, they were part of families or communities that used photography to keep their memories and of their groups so that they could perpetuate the images of these children. The analysis allowed the visualization of a feeling of black childhood, demonstrated by the signs of how children were taken care of which were preserved and recreated by black adults in the Brazilian slavery context.

The question of rural development has been discussed by different agencies and agents, governmental or otherwise, that directed the discussions towards convergence between the questions of agriculture, agrarian and environment. In this approach, the conservation and restoration of natural resources are considered as important as the agricultural production. In Brazil, this approach has placed the agrarian reform settlements as areas important for the implementation of agricultural projects based on environmental sustainability. The case study we developed in a rural settlement in the municipality on the Ribeirão Preto, region northeastern state of Sao Paulo shows that the implementation of such projects exacerbates conflicts between the agents and expressed the fragmentation and dislocation of public policies for rural settlements. Comparing the different discourse and practices, we aimed to understand what is an environmental sustainability for the state, social movements and rural workers settled.

The changes occurred in our society in the last few years have immediately reflected in the school sphere. Nowadays, in the educational context there is a great international effort in favor of the inclusive education, which proposes to welcome students from any belief, race, social or financial background and who also may have any kind of disability. In this direction, this research has as objective to investigate the perceptions of deaf and hearing impaired students, included in state schools, concerning the teaching and learning process of a second language as part of the school curriculum, and therefore discuss the legislation which obliges those students to be in regular classrooms as well as the questions brought about regarding the process of inclusion. The subjects of the research are deaf or hearing impaired students from the 5th grade Elementary School to the 3rd grade High School, in the region of Araraquara, São Paulo, Brazil. It is a qualitative research, whose data were collected throught: (a) classroom observation; (b) questionnaires and interviews, intermediated by a professional specialized in sign language and (c) drawings. As a result, the data analyses have revealed that the students degree of language knowledge, of performance and of inclusion is related to individual characteristics.

This PhD thesis covered was devoted to the preparation of nitrogenated intermediates by multicomponent reactions (3-MCR) with potential application in the bioactive compound synthesis. The developed methodology consisted on the coupling reaction of an organometallic compound, formed by an alkyne and a metal salt or complex, and a nitrogenated electrophile like as imines or iminium salts. In the first part of this work we reported the A3 coupling reaction of aldehydes, 4-piperidone hydrochloride monohydrate and alkynols giving the corresponding hydroxy alkynyl piperidin-4-ones, which are important synthetic building blocks. In the second part of the work was developed a coupling reaction using benzylamine as primary amine source in order to prepare amino alkynols with the benzil group. These compounds were employed, as synthetic intermediates, in the synthesis of bioactive five, six and seven membered alkaloids.

Historically, quests where frequently used by players, which empirically analyzed and systematized them with the intention of revealing the inner structure of games. After that, there was a need to address them as the primary object of study, observed by the academy. Therefore, the narratives through quests in MMORPGs was choosen as the object of study, specifically how the stories are told using quests in World of Warcraft (Blizzard Entertainment, 2004), identifying both the main structural and functional characteristics of storytelling, which allows a differentiation between various types of quests. The aim is to demonstrate that the narrative through quests in World of Warcraft is different from other structures and that the fragmented structure of quests is presented as a form of serial narrative, which allows the construction of a fictional world that is broad and deep at the same time. The analysis of narrative structure within complex systems such as virtual worlds of MMORPGs allows not only to review the way we understand the relationship of the narrative with videogames, but also can expand the way we understand the very act of storytelling.

The current paperwork intends to analyze the concept of drive in both first and second theories of drives according to the Freudian psychoanalysis and refers to the behavioral biology in order to initiate a debate about the Trieb concept between these two areas of knowledge. According to Sigmund Freud, the concept of drive is the most important one and also the most obscure for the metapsychology. The complications regarding the meaning of this concept begin with translation problems and with divergences among several schools of psychoanalysis, which postulate different comprehensions referring to the word Trieb and Instinkt and referring to the way Freud used them in his texts to talk about the development of the psychic apparatus and its place in the construction of metapsychology. The view on the Instinkt drive being a totally inherited and automatic behavior is a misunderstanding for the own scientists in the area of behavioral biology. Freud uses in his texts the concepts of Trieb and Instinkt in turns and this research tries to elucidate if there was the need of this distinction and, thus, an emphasis is given on the definitions that Freud has postulated about the nature of both, sexual drive and death drive. Besides, the beginning of a dialogue between these Freudian concepts and the sexual drive and the drive of aggressiveness in the sociobiology of Edward O. Wilson and in the behavioral biology of Konrad Lorenz is carried out.

This thesis presents three manuscripts derived of two research projects that were developed during the doctorate program. Project 1. Purpose: To determine the interand intra-rater reliability of nerve conduction studies (NCS) of superficial peroneal, sural and medial plantar nerves. Methods: Two raters performed the bilateral NCS twice in 20 healthy participants (23.5±3.5 years). Reliability was analyzed by the Bland- Altman method and intraclass correlation coefficient (ICC). Results: The Bland-Altman method showed a good level of intra- and inter-rater agreement for all parameters nerves. The amplitude and latency of the medial plantar nerve (rater 1), as well the amplitude of the sural nerve (rater 2) had an intra-rater ICC ≥0.75. Inter-rater analysis showed concordance levels between moderate and very low. Project 2. Purposes: a) To compare the effects of three cold modalities on the nerve conduction parameters of the sural (sensory) and tibial (motor) nerves during cooling and post-cooling phases b) To analyze the effect of exercise on recovery of sensory and motor nerve conduction velocity (NCV). Methods: Thirty six healthy young subjects (20.5±1.9 years) were randomly allocated into three groups: ice massage (n=12), ice pack (n=12) and cold water immersion (n=12). Each group received 1 of the 3 cold modalities on the right calf region for 15 minutes. The subjects of each modality group were again randomized to perform a post-cooling activity (30 min rest or walk 15 min followed by rest 15min). Nerve conduction parameters of sural and posterior tibial nerves were evaluated. Results: All 3 modalities reduced amplitude and increased latency and duration of the compound action potential. Ice massage, ice pack, and cold water immersion reduced NCV by 20.4, 16.7, and 22.6 m/s and motor NCV by 2.5, 2.1, and 8.3 m/s, respectively. Cold water immersion, as applied in this study, was the most effective modality in changing nerve conduction parameters. The walk accelerated the recovery of sensory and motor NCV, regardless of the modality previously applied (p<0.0001). Conclusions: The NCS provides quantitative measures that contribute to the objective analysis of neural physiological effects of cryotherapy. All 3 modalities were effective in altering sensory and motor nerve conduction. However, the magnitude and duration of these effects depend on the method applied and the activity after cooling.

There were substantial changes in the 90s decade in brain researchs, when one begins to discuss the benefits of an alignment of interests between the areas of Neuroscience, Psychiatry, Cognitive Psychology and Psychoanalysis. Fact that it was linked to the change of perspective in sciences cognition and neuroscience, from a cognitive perspective to a dynamic and motivational view, in theory, more able to include aspects of subjectivity in the modern field of the study of mind. The psychoanalytic literature is very resistant to a renewed discussion of metapsychology, however there is no denying the construction of a notion of interdisciplinarity between the brain sciences and psychoanalysis (and psychological sciences in general). This Thesis intends to discuss some contemporary proposals of convergence between the neuropsychiatric and psychosocial formulations, in view of an interface between cognitive neuroscience and psychoanalysis, using Freudian concepts about the ego (Ich) as head theme. The search for the greatest integration between these formulations of the ego in Freudian theory could possibly contribute in reflecting on the debate on the rapprochement between psychoanalysis and neuroscience. We present the dialogue that some programs offer neuroscience for psychoanalysis. Does Freud's 19th century has to offer some contribution to what is named today as a new biology of mind? How to recover his thought could supply some conceptual and methodological shortcomings of these programs neurobiological? Psychoanalysis would be on the verge of losing its identity amid the current intellectual scene of the brain sciences? The aspirations of this multidisciplinary research about the mind and brain could open new horizons for psychoanalysis? The search of neuropsychological origins of Freudian metapsychology has opened a range of discussions, both in the neuroscience community, as in psychoanalysis. Instead of taking immediate support or a refusal to this interface is proposed that much like integration , this work suggests that the inquiries are referred to their own conceptual and methodological frame of neuroscience programs and examination of the Freudian theories, for knowing whether these concepts are open to this kind of reading - thus avoiding hasty conclusions and simplifications to that proposal.

Arsenic is an essential chemical element for life, although it can be extremely toxic at concentrations slightly above those required for living organisms. In Brazil, generally well-standardized internationally test organisms are used in Aquatic Toxicology. Although sensitive, it does not occur in Brazilian ecosystems, increasing the difficulties on assessing the impacts of chemicals on specific niches of the local biota. Furthermore, the toxicity test using exotic species, do not match the tropical and subtropical ecosystems abiotic conditions, which have different characteristics such as conductivity, hardness and temperature, among other variables that modify the response of test organisms and even the own toxicity of the chemical agent. Thus, ecotoxicological assays are of utmost importance when using native species, in order to assess it sensitivity to several toxic agents. The present study was proposed to assess for the toxicity of Guamium River bottom sediment, Piracicaba hydrographic basin, São Paulo, by using test organisms such as Paramecium caudatum protozoan Ehrenberg, 1833 and Ceriodaphnia silvestrii cladocera Daday, 1902. To reach for these goals two sampling campaigns were carried out, one in the dry season and another during the rainy season, in 9 points through the entire length of the river main channel, to verify spatial variation as a function of different surrounded land use. Sediment samples were analyzed for total and available As, As3+ and As5+, relating the obtained data with acute toxicity bioassays results for inorganic As species. Taking into account the modification of As oxidation state by the sample preparation conditions, in the rainy season, analytical results were compared to those predict by the pH x Eh stability diagram. Total and inorganic As species were also determinate in the Certificated Reference Material WQB-1. The acute toxicity of As3+ and As5+ solutions were evaluated for zooplankton, by using the same test organisms, quantifying the absorption/adsorption of the semi-metal in the experiments organisms. Chemical analysis of sediment samples resulted in toxic levels concentrations of total As, As3+ and As5+, especially in the Points of the River s Source (P0), Tanquinho s District (P1) and Dial Animals (P5) of Guamium River, confirming with the points at which the supernatant had higher concentrations of total As. The results obtained from the sediment analysis were similar to the theoretical values provided using the pH x Eh stability diagram, which indicated prevalence of As5+. The method of determining total As presented analytical precision when it was compared to the Certificated Reference Material WQB-1, which like the samples, presented different fractions of As in its inorganic form. According expected by the literature, the reduced form (As3+) was more toxic than the oxidized form (As5+), and C. silvestrii is more sensitive to arsenic and sediment samples than the P. caudatum. By spectrometry of atomic absorption technique with electrothermal atomization in graphite furnace (GFAAS) it was determinated As levels in the surviving organisms and in the case, the dead of the highest concentration used. In protozoan, the bioaccumulated levels ranged from 29,8 to 70,0 pg x individual As3+ or 10,5 to 17,5 μg x g-1 of dry weight (dw) As3+ and from 183,0 to 282,6 pg x individual As5+ or 45,8 to 70,7 μg x g-1 dw As5+. In cladocera, the levels ranged from 75,9 to 149,3 pg x individual As3+ or 22,4 to 44,1 μg x g-1 dw As3+ and from 1.575,4 to 1.630,2 pg x individual As5+ or 465,2 to 481,4 μg x g-1 dw As5+. Even considering both, the tested organisms small size and the low concentrations used, it was possible to associate with As, bioaccumulating this semi-metal and, thus, has an important role in the bioavailability of this along the food chain.

In recent years, research on Portuguese as foreign language teaching and learning has been the recipient of great academic interest. This is due to several factors, such as the creation of international partnerships (MERCOSUL), easier mobility (tourism) and interest in Brazilian nature and natural products. Furthermore, Portuguese is the native language of more than 250 million speakers, which makes it the sixth most spoken native language in the world, and the third in the West. In this growing field of research, one prominent topic is educational materials, and more particularly educational books used for teaching Portuguese as foreign language. In this dissertation, educational books are considered a multimodal genre that is crucial in the teaching-learning process (which also involves teachers and students). Considering educational books multimodal/multi-semiotic character, we propose an analysis of the images/pictures/photographs portraying Brazilian people and land. Based on the images presented by educational books, this study s guiding question is: how are Brazilians and Brazil portrayed in Portuguese as foreign language educational books? Thus, the investigation is carried out as qualitative research, as it follows criteria of representativeness, not of probabilistic sampling.
