When children with a history of school failure report on the outcomes of reading responses, most of them tend to report mostly correct responses, even after they make mistakes. This study investigated variables influencing correspondence in these reports and attempted to train correspondence to ensure accurate reports of errors, as well as of correct responses. Experimental sessions presented series of words on a computer screen. The computer dictated the correct word and children selected a green or a red window to report that the response had been correct or wrong. Baseline sessions showed that reports of errors as correct responses increased as a function of error probability. Training sessions then reinforced correspondence, providing points contingent to selections of the green window after a correct response and selections of the red window after an error. Correspondence quickly increased and was maintained in subsequent baseline sessions. Correspondence training was effective to establish accurate reports of errors in these children.

The present study is at the scope of investigation which search to understand how it s been developed the teaching and learning processes of the specific didactics in Pedagogy Training Course for experienced teachers. More effectively, its is directed to the understanding of teaching and learning at the subject Geography on the Pedagogy First Initial Series of Primary School course, at the Universidade Estadual de Feira de Santana (UEFS). Even though many courses have been implanted in the past few years involving this public, its still rare the researches dedicated to the understanding of its contributions to these teachers practices. These scarcity, together with a particular interest in contribute with the deepness of the question, is the reason for me to do this work, guided for the following question: How do the egresses from the degree in Pedagogia Séries Iniciais do Ensino Fundamental at UEFS, describe and analyze the Geography teaching developed at the course, considering the contributions to the development of their practices inside the classrooms? The theoretical references adopted were: to discuss teaching learning and professional teaching knowledge, we considered the contributions from Maurice Tardif, Marcelo Garcia, Pérez Gómez and, to discuss the different approaches in Geography we adopted the works of William Vesentini, Helena Callai, Lana Cavalcanti, Nídia Pontushcka. In order to do the investigation, we selected seven egresses who were teaching the subject Geography at the first initial series of Primary School since they have finished their degree. The main data collection instrument was the individual interview together with a questionnaire, using a qualitative approach as a research reference in their paths as students of the Basic Teaching and in the course of Pedagogy, in UEFS. It was clear the change in the way of to understand and to teach Geography. The first was the one of the book, of the copy, of the "decoreba"; it was the learned Geography, just, to answer the subjects of the proof. The second was developing of another perspective, characterized essentially by his/her relationship with the concrete life, with the reality of a world that is unequal and unjust. Besides, the data revealed some changes in practice of the current participants of the multiple relationships with the knowledge locked in the degree, besides in the discipline Ensino de Geografia. But they had disclosed also that not learning had of contents specific (concepts, facts, methods of education) and nor of a conception of formation based in the theorypractical relation that they allowed them to develop an education of analysis, critical and reconstruction of the proper teaching exercise.

More and more, the society has required citizens to act in a world which scientific and technology knowledge is extremely worth. The evolution of these knowledges works as a modern world´s mirror, which, indeed, reflects all the progress that conduced to the development of the actual society, consisted by the amazing velocity the information is spread, and by the incredible science dynamism. In this way, make people get closer from informations about science takes an important and challengeable role. Important since it leads you to a world comprehension and its information; challengeable because of the complexity that involves the teaching and learning task. The science studies has to act as a contributor to the reality comprehension, mainly in understanding the natural events, stimulating questions about the differents ways the interventions can modify them. In that case, the investigation of the questions that covers the learning process of teaching modality since basic grades becomes indispensable, as we think about the developments coming from critical people who are acting directly on the society. The main purpose of the present work was to obtain elements that could bring possibilities of proofs, reflections and discussions around the science teaching in basic grades, especially on the fourth grade, which is the focus of this research. For that, it was necessary an approximation to science teaching history and to the different sources teachers acquire to be able to get the knowledges which state their praticals, involving questions about the science curriculum, materials used within the classes and others aspects that leaded to a bigger approximation to the process of teaching and learning. The investigation started from a theoretical reference based on teacher s knowledges. Therefore, a better comprehension of how teachers relate with the knowledges that are used within their science classes and how those knowledges are acquired were better understood.

This work aimed the investigation of ultra thin, polymeric film compositions made by the layer-by-layer deposition technique capable of coffee quality classification accordingly to stablished standards, using electrical impedance measurements and the statistical method Principal Component Analysis. Films made of polyaniline, poly(o-ethoxyaniline), polypyrrole, poly(3,4- ethylenedioxythiophene), poly(hexamethylene biguanide), poly(sodium methacrylate), fatty acids and derivatives, and other materials were studied. Films were grown showing the applicability of these materials to self-assembly of sensors based on polymeric materials. It was verified that PANI and DBSA has a great potential as materials for sensor construction by such process due to high rates of film growing. Itl was also observed that PEDOT(PSS) alternated with PHMB(HCl) was the better material combination for coffee evaluation. Impedance measurements in broad spectrum and use of variance-based ranking factors allowed selection of optimum operation frequency for each sensor, aiming the classification of brewed coffee by Global Quality and bean type. With this strategy, it was also possible to determine those materials that presented the best responses. Experimentally, it was shown that coffee deposition occurs on the electrode surface during the time of measurements, and proved that the usual washing procedure was not efficient to remove all adsorbed coffee compounds, being necessary the washing with detergents. The results of this work allows the construction of a sensor array to classify commercial coffees by Global Quality, and the optimization of a sensor array specialized on defective beans, which previously could not be determined on commercial samples of roasted coffees.

Hesperozygis ringens, belongs to Lamiaceae s family, it is an aromatic plant native from the South Brazil with its occurrence restrict south fields mainly in Caçapava do Sul, Alegrete and São Francisco de Assis. Due some activities agropastoris like continuous cleanness and burning to the renovation of grassland associate with some factors like low seed efficiency propagation, these spices are in extinction process. In order to evaluate the effect of these activities at the extinction process of this plant were used molecular markers RAPD and ISSR to evaluate the genetic variability, chemical variability of the essential oils and effect of the growing regulators in the micropropagation. With molecular markers we check a low gene flow between studied populations, with distinct genetic entities, sharing the samples in isolated clusters from Alegrete, São Francisco de Assis and Caçapava do Sul, the last one was evaluate in two populations A and B witch showed a larger gene flow between samples. The chemical variability data were confirmed by markers RAPD and ISSR, because they shared the populations in two isolated groups, characterized for to present compounds with low frequency like limonene and linalool in the São Francisco de Assis population, and the others were not present as sabinene in Caçapava do Sul. In the in vitro propagation the MS medium showed the best results supplemented with 13.2µM of benzyladenine and 2mg/l of silver nitrate, witch were used to avoid ethylene accumulation effect. The rooting showed limitation with low efficiency, but was obtained with carbonized rice back, with ¼ MS supplemented with IBA. Even with hardness the micropropagation can be an alternative for the propagation and preservations of this endangerous species. Based in this results of this work were discussed about environmental, evolution and conservation aspects.

This research, of a qualitative nature, investigates aspects of the learning process of the teaching staff, in order to contribute to the continued in-service learning for teachers in the use of computers in their teaching practice. The preparation of teachers to work with computers in education has been occurring, usually, by means of courses given outside of the context of their work. However, this study seeks to analyze the possible contribution of a proposal of continuing education in the work place, to make possible new competence and abilities in the use of computers in the classroom. The study was carried out in a private school in the city of São Carlos, SP, and its central focus was the development of activities within the context of the reality of school and teacher, using software applications as teaching tools in the construction of projects. The methodology adopted is associated with a constructive-collaborative model of research and intervention, in which the people involved, teacher and pupil, play roles of a collaborative nature, as partners, in a multi-faceted relationship. The theoretic contribution established a relation among computer science, education and teacher training, emphasizing the advance of technology in education and the roll of the school and the teacher in relation to new and growing educational demands, in a constantly evolving technological scene. The data obtained indicated a concern on the part of the investigated teachers to appropriate for themselves skills that makes it possible for them to use computers in the classroom. They recognize the usefulness of the computer in teaching, however they point out some limitations, such as the lack of ability and the difficulty of developing educational activities using the computer, the lack of time available to learn to use the computer in view of other teaching demands, and the lack of equipment and educational software for use in the class room. It was evident that, in the training environment, the production of innovative educational practices came about through reflection on shared experiences. It was indicated that there is a need for the training programs for teachers to have as their axis the context of their use, and and for the creation of a culture that permits the teacher to become a critical user of technology, using it in her teaching, and becoming her own agent of change.

Brazilian colonization occurred without a specific planning and, as a consequence, natural resources, particularly forests, were greatly affected specially by economic interests. In the Brazilian history, the native land cover vegetation was removed, and substituted by agriculture, mainly of sugar cane and also pastures. In the State of São Paulo, the sugar cane culture has also being enlarged, with the annual production of the about 200x106 tons covering an area of 2.5x106 ha. The use of herbicides and fertilizers containing different concentrations of the metals Pb, Ni, Cr, Cd and Zn, during different periods of cultivation of sugar cane, in addition to the deforestation of riparian vegetation, have caused impacts on the hydric resources of the adjacent areas. In the present work, the influence of the agricultural activity, in particular, sugar cane culture, on stream macroinvertebrate communities was studied. Macroinvertebrates, sediments and water were surveyed in three periods: March/April, 2002; June/July/August, 2002; October/November, 2002. Thirty three samples were collected: 15 in streams with sugar cane culture, 12 in streams with riparian vegetation and 6 in pasture areas. The concentration of the dissolved oxygen was low in streams without riparian vegetation (sugar cane and pasture) when compared to preserved areas. The concentration of the metals Cu, Fe, Cd, Zn, Mn, Cr e Ni of the sediment were high in streams with sugar cane cultivation, with significant differences to Cu and Zn, when compared to forested streams. The streams located in the adjacent areas with sugar cane cultivation also present high concentration and frequency of occurrence of the 15 organochlorine compounds analyzed. In this study, 3365 organisms were collected, in which 54 Chironomidae taxa and 42 of other aquatic macroinvertebrates. The streams located in areas of sugar cane culture and pasture (opened areas) presented low taxa and a great participation of Chironomidae (78% of the total). In contrast, the streams located in areas with riparian vegetation presented a rich aquatic fauna with less participation of Chironomidae (60% of the total). The community index, in addition to other measurements, applied to the stream macroinvertebrates community of the 11 streams pointed out to major values of richness, diversity and biotic index to the streams located on forested areas, when compared to the streams located on areas with sugar cane cultivation and pasture. Overall our results indicated that deforestation of the riparian vegetation was the principal aspect that influenced the stream macroinvertebrate communities. The loss of the riparian vegetation in the streams located adjacent of the agriculture areas establish an environmental impact that results in a poor taxa richness and shows clearly the necessity of a suitable management of the hydric resources of the southeast region of Brazil.

Studies accomplished in the structure of tubular fixed beds proved that the porosity in these systems presents an oscillatory behavior along the radial direction. The non-uniformity of the porosity generates a behavior of the velocity profile, inside the bed, characterized by oscillations in the central region and a peak of larger width in the region close to the wall. This velocity profile determines the residence time of the reactants, for example, and presents a strong influence in the heat and mass transfer coefficients of these systems. In spite of the progress obtained in that subject, it is still difficult to obtain the measure of flow velocity inside the bed without causing disturbances in its structure. Due to this restriction, indirect forms of experimental measure of the velocity distribution in these systems have been proposed to evaluate the fluid dynamics inside the bed. The most common way to obtain, experimentally, the velocity distribution inside the bed is to measure it outside the bed, at a certain distance from its exit, and then infer it inside the bed by considering that the flow measured at this point maintains the fluid dynamics characteristics at the interface. Looking for an alternative way to infer the velocity profile inside the fixed bed, this work proposes a measure of the change in flow characteristics from the exit of the fixed bed to the point of experimental measurement. The measure proposed before takes into account the change in the radial mean velocity evaluated over an area close to the central part of the flow. This measure is based on simulated results accomplished between these two points, located outside the fixed bed, from an appropriated boundary condition at the interface. This boundary condition at interface is the result of other simulations performed inside the fixed bed, from a convenient model proposed for this region. Both simulations were accomplished by using a simulator developed in FORTRAN language, based on a CFD numeric technique for outside and a standard finite difference method for inside the fixed bed. The validity of the proposed procedure was verified by comparing the velocity distribution simulated at a position pointed out in an experimental measurement of the velocity distribution obtained in the literature, and with similar operational conditions. By doing this validation, it was established a relationship between the change in flow characteristics and the axial position of measurement. As a result, it was possible to infer how much of the flow characteristics in the interface are observed from the position chose for measurement along the axial direction of the flow. Better results were observed in systems with a high dimensionless D/Dp relation and low values of Reynolds number for the flow simulations accomplished in the exit area of the bed. Deviations from experimental data, varying between 2,97% and 30,23%, were verified for different operational conditions of the system. Through the central velocity simulation along in the empty tube axial position, were possible to map the empty tube influences on the flow in the fixed bed exit area, evaluating the difference of that central medium velocity with the calculated for the bed exit.

Many studies have shown that object properties can lead to adjustments in reaching, but few have investigated the specific influence of object size and rigidity on reaching movements in young infants, especially by using kinematic analysis. Objective: Investigate the effect of object size and rigidity in the qualitative and quantitative variables of reaching in 4-to-6- month-old infants, and verify how such variables change over age. Methods: Nine healthy infants were placed in a baby chair reclined at 50º from the horizontal The infants were shown four objects of different size and rigidity large rigid (RG), small rigid (RP), large soft (MG), and small soft (MP) for a period of 1 minute each. Reaching movements were recorded by three digital cameras and the images were analyzed by using the 3D movement reconstruction. A total of 378 reaches were analyzed in relation to the following variables: qualitative proximal and distal adjustments, hand preference, and grasping of objects ; and quantitative straightness index, mean velocity, movement units, and adjustment time index. Results: There were many different changes in reaching over age. The answers to stimulation and the grasping of objects increased. Proximal adjustments were shown to be variable. Hand preference changed from the left to the right. The hand was predominantly half-opened in both the beginning and the end of the reaches; however, hand opening angle increased in the end of the reaches from the fifth to the sixth month. In all the ages, hand orientation was predominantly oblique when touching the object, and vertical when grasping it. As regards the quantitative variables, the straightness index and the mean velocity increased, and the movement units decreased. No significant changes were observed in the adjustment time index. Infants performed bimanual movements for the large rigid object, and unimanual movements for the small ones. The adjustments were similar in relation to the large soft object. Right-hand preference was higher for the small objects. In the beginning of the reaches, the hand was predominantly half-opened for all the objects; while in the end of the reaches, the hand was predominantly opened for the object large rigid. Hand orientation was predominantly oblique when touching the object, and vertical when grasping it, especially for the object large rigid. The soft objects were more frequently grasped than the rigid ones. The straightness index was higher for the large soft object, while the adjustment time index and the number of movement units were lower for this same object. The number of movement units increased for the small objects. No significant changes were verified in the mean velocity. Conclusion: It is possible to suggest that reaching movements are improved over age, thus indicating an increase in the infants performance during the studied period of life. Once the infants perceive the object properties, they adjust the essential variables of their movements by using their available motor abilities, thus suggesting the existence of a complex perceptionaction coupling.

The PET filter bag is used in the separation of the particulates materials of the gas produced in the aluminum industry. It had been submitted a chemical recycling. Almost industries make the disposal of these materials in industrial earthwork or still they take the centers that make the energy recycling. The filter bag restrained particulate is constituted by alumina with adsorbide fluoride and an amount of carbon proceeding from the electrolytic decomposition of anode pots. The adhesion of particles in the interior becomes the filters of difficult recycling mechanics, because the incrusted materials are not removed by the laundering. So, the filters of this work had been recycled chemically through glycolysis with ethylenoglycol. For the reactions under ambient pressure it was observed that it has the necessity to use catalyst to speed up the reaction. The catalyst used was the sodium bicarbonate. The best condition found for reactions the ambient pressure form: temperature of 190°C, 1% of catalyst and 20 hours of reaction. With these conditions the glicolysis convrtion was almost 94%. It was not possible to determine the order of ration for this system. The reactions carried through with a closed reactor had allowed increasing the temperature of the system. So, the temperature is the variable most important, reaching bigger conversions in a lesser time that the gotten time the ambient pressure. The best joined conditions had been 1% of catalyst, 190°C and 10 hours of reaction and also 0.5% of catalyst, 230°C and 5 hours of reaction. For these conditions, the reaction rate was little bigger than 99%.

Urban problems caused by transportation planning that prioritizes the use of the automobile indicate the inclusion of the bicycle as a viable alternative of urban transport in Brazilian cities. However, it is verified the lack of guidelines that can lead to policies that encourage bicycle transportation, amongst which stands out the insertion or improvement in the infrastructure for cycling. The objective of this study is to propose a method for the definition of cycling routes in urban areas which would have satisfactory results in encouraging bicycle transportation, focusing on the aspects of demand and bicycle level of service in shared roads in urban areas. The proposed method includes the following steps: (1) identification of the potential facility for bicycle trip generation; (2) data collection on the trip behavior of the facility users; (3) identification of the road segments with greater potential demand for bicycle trips; (4) level of service evaluation of the selected road segments; and (5) selection of road segments with greater need of improvement to define cycling routes. A study case was carried out in the city of São Carlos, where the proposed methodology was applied in two utilitarian bicycle trip generation facilities. The necessary data for the study was obtained through 106 interviews, which included a questionnaire and a stated preference survey. The data obtained in the stated preference survey revealed that the pavement condition was the most important attribute in the group s opinion, in comparison to motorized vehicles speed and travel time. The identification and the study of the road segments with greater potential demand for bicycle trips included the demarcation of the influence area of the trip generation facility, the definition of the desire lines and the inventory of the itineraries covered by the interviewed group. These steps were developed with the use of TransCAD. The evaluation of the level of service of the selected segments resulted in measures of level of service with the same value for all of the roads, which did not allow us to prioritize the segments with greater need of improvement to define cycling routes. However, since the values attributed to the road segments were considered unacceptable for bicycle transportation, a series of improvements were suggested to reduce their deficiencies.

In this study, we investigated the participation of the AT1 receptors and of the nitric oxide (NO) into lateral septal area (LSA), on the water intake, 0,5 M NaCl intake, natriuresis, diuresis and pressor response induced by injection of angiotensin II (ANG II) in the same area. Male Holtzman rats were used weighing between 280 and 320 g, with cannulae of stainless steel implanted stereotactically into the LSA. The ANG II (25 ng/0,5 µl) injected into LSA, induced water and sodium intake and increased the urinary volume, sodium urinary excretion and arterial pressure when compared with the control group, that received 0,15 M NaCl. The pretreatment with losartan (antagonist of the AT1 angiotensin receptors) into LSA abolished the water intake, the sodium intake and the pressor effect induced by ANG II. The losartan also reduced the increase of urinary volume and of the sodium excretion induced by ANG II. The previous treatment with 7-nitroindazole (inhibit of the nitric oxide synthase enzyme) abolished the water intake and the increase of urinary volume, decreased the sodium intake and the natriuretic effect and no changed the pressor effect induced by ANG II. The results show the involvement of the AT1 angiotensinergic receptors and of the nitric oxide into LSA in the control of the cardiovascular and hydroelectrolytic balance, beyond a possible interaction between nitrergic and angiotensinergic mechanisms of the LSA in this control.

The worldwide (and thus Brazilian) automotive industry has undergone a process of important changes. Specifically in Brazil, the set up of new automakers, the consolidation and denationalization of the autoparts, and phenomena like the lowdisplacement engines have brought major strategic implications to those companies, as well as to the supply chains to which they belong. Considering such implications, it is plausible to accept that several organizational elements were strongly impacted, including Operations Strategy and the Strategic Logistics Management focuses of this research. In this sense, the work here presented aims at shedding light on the alignment between Operations Strategy (OS) and Strategic Logistics Management (SLM), by means of case studies carried out at four companies from the Brazilian automotive engine sector (two car engine manufacturers and two of their suppliers). The main findings indicate that operations and logistics are effectively aligned in the cases studied, but such alignment is influenced by aspects regarding the supply chains to which these companies belong, as well as by aspects internal to such companies. As a consequence of the differences occurring in the chains, although the companies adopt similar competitive priorities, they are implemented by different decisions. Regarding operations, the chains seem to influence the decisions and viceversa, whereas regarding logistics the chains create a framework in which logistics may play its role in the company strategy. Organizational structure and the role that operations play in competitive strategy were the internal aspects here analyzed. The first seems to make the alignment easier, once that in most cases both operations and logistics were managed by the same director. The role played by operations also suggested alignment, once that operations decisions either aimed at implementing the strategy, or originated such strategy from its competencies.

Many studies have shown that children exposed to domestic violence are at risk of presenting behavior problems and other adjustment problems at school. Nevertheless, few studies have assessed the relationship between different types of family violence and bullying. The primary purpose of the present investigation was to: a) examine the relationship between bullying and different types of direct and indirect family violence in Brazil; b) check the chronicity of family violence among student subgroups implied in bullying; c) establish if there are gender differences concerning these associations. The research was conducted with 239 grades 5-8 students, of which 34.7% were boys and 65.3% girls. A questionnaire was constructed based on other instruments, containing: 12 questions involving socio-demographic variables; 16 items of the Revised Conflict Tactic Scale (CTS-2), with the goal of examining the youngster s exposure to interparental physical and psychological violence; and 32 items of the Parent-Child Conflict Tactics Scales (CTSPC), concerning physical and psychological abuse committed by parents against children. Bullying and victimization were measured by 26 items developed specially for the study s purpose, based on a modified version of Olweus questionnaire. It was found that, in the previous three months before the study, 49% of all students were implied in bullying: 2,9% as bullies, 25,5% as victims and 20,5% as bully/victims. It was found that boys were more implied as bully/victims than girls. More than 50% of the participants had witnessed at least one episode of interparental psychological aggression, and 12% of all students reported seeing physical violence between parents, with fathers and mothers showing an equal ratio of violence. In regards to child abuse, psychological violence was the most frequent modality, with 85% of participants reporting that they had been victimized that way by mothers and 62%, by fathers. The rates of physical assault were also alarming: about 70% of all students reported that they had suffered corporal punishment by parents, which is worrisome. Associations were found between bullying and domestic violence, but these associations were different according to gender. Being exposed to domestic violence was associated with being a bully/victim in school (especially for girls), but not with being a victim of bullying. On the other hand, parental violence increased the probability of boys reporting being implied in bullying as victims or as bully/victims. In terms of the girls, suffering parental violence was only associated as being a bully/victim. In this study, being an aggressive-victim meant having more chance of suffering domestic violence, and such violence was more severe than the one reported by students not implied in bullying or victims of bullying only. Due to the small amount of participants classified as bullies, it was not possible to do statistical tests, which was a limitation of the study.

The physiological and biochemical responses to air exposure were analyzed in jeju, Hoplerythrinus unitaeniatus at 1(T1), 6 (T6) and 12 (T12) hours of exposure and 1 (TR1) e 6 (TR6) hours after returning to water environment. Plasma cortisol and glucose were significantly higher than those of control group (T0) after 1 and 6 hours and 1, 6 and 12 hours of air exposure, respectively. Acid-base and ionic unbalances during air exposure were evidenced by plasma pH and Na+ and K+ concentration following pH recovery as fish returned to water environment. Ammonia accumulation was found in all experimental groups increasing continuously during air exposure (from 102.20 nmol/mL in T0 to 339.53 nmol/mL in T12). During the recovery period in water there was a reduction in plasma ammonia concentration but it was significantly higher than the controls. Plasma lactate showed a slightly increase during air exposure and was significantly higher than the controls only 1 hour after recovery in water (from 4115.42 nmol/mL in T0 to 6423.84 nmol/mL in TR1) while piruvate increased after 6 hour in water (from 171.87 nmol/mL in T0 para 243.96 nmol/mL in TR6). Hematocrit, red blood cells, hemoglobin concentration and mean corpuscular hemoglobin concentration increased significantly during air exposure. On the first hour of air exposure the lipid hydroperoxide (HP) increased. There was a reduction of catalase (CAT) and superoxide dismutase (SOD) activity and an increase of glutathione peroxidase (GPX) during air exposure. Air exposure can be characterized as an stressor agent to H. unitaeniatus and imply in physiological adjustments to keep the O2 transfer from air to tissue and homeostasis as well as energy mobilization.

(Gelatinous aggregates (lake snow) from an eutrophic Brazilian reservoir and their relationships with abundant phytoplanktonic algae). Lake snow and phytoplankton studies were conduced in Barra Bonita Reservoir, in the Tietê River basin, southeastern Brazil. Monthly sampling from April 2002 to January 2004 and two intensive sampling (dry and wet periods) were performed in six depths (0m, 1m, 3m, 5m, 10m and 17m deep), at a sample station localized 3km upstream the reservoir dam. Among the sampled months the highest numbers of aggregates were registered in August 2002 (167 agg.L-1) and September 2002 (230 agg.L-1). The mean numbers of aggregates registered in the intensive samplings was 38 agg.L-1 in June 2003 and 68 agg.L-1 in December 2003. Seasonal occurrence of algal species aggregated to polysaccharidic matrices followed the dynamic of dominant species in the Reservoir. Aulacoseira granulata and free cells of Microcystis sp. were the most frequent taxa in the aggregates (70%) in the majority of samples. Other species, as Pseudanabaena mucicola, Microcystis aeruginosa, Planktothrix tropicalis, Cyclotella menegheniana, Cryptomonas sp, Actinastrum hantzschii, Quadrigula lacustris and Schroederia indica were registered in less frequency (10% to 15%). The monosaccharide composition of the gelatinous aggregated polysaccharides was the same registered in dissolved carbohydrates samples, reinforcing the importance of phytoplankton as the major source, chiefly of polysaccharides and of the gelatinous aggregates in the transport of these sugars through the water column. However, studies concerning gelatinous aggregates in freshwater are recent and more investigation are needed to confirm the patterns showed in our results.

The present work seeks to elucidate the notion of Real in Lacan, from the first writings to the seminar VII, The Ethics of the Psychoanalysis. Initially, the relationships are privileged: Imaginary and Real; Symbolic and Real; Symbolic, Imaginary and Real. After the elucidation of those relationships, it is advanced for the moment of transition of the concept of Real, redoing Seminars IV, V, VI and some referring texts to them. Here, Lacan is verified retaking the present idea from the seminar III, The Psychoses, that the Real is what always comes back to the same place. It is arrived, like this, to the seminar VII, dedicated to the Ethics of the Psychoanalysis, in that is shimmered the relationship among the Real and das Ding. He/she/you sees her, here, that the Real is of the order of das Ding. The Ethics of the Psychoanalysis, of that sorts things out, it is centralized in that Real one and it emphasizes the sublimation as the one that elevates the object to the dignity of das Ding. The work is concluded affirming that Lacan, more ahead in your teaching, it will formulate the Real as being of the order of the impossible, as well as it will be served as the knot borromeano, interlacing, once and for all, the three registrations: Real, Symbolic and Imaginary.
