(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.

In this work we consider an of - resonant interaction between optical fields and a Bose - Einstein condensation. We used a continuous photo detection model to study the efects of the counting of k photons of the optical field upon the properties of the atoms in the condensate. We have obtained the density operator of the interacting system conditioned to count k photons and one relation between the moments of the distribution of photons and the moments of the distribution of atoms. We analyze the efects of the photo counting in two specific cases: in the first case, we analyze the efects of the photo counting upon the state of a pure condensate at zero temperature and in the second case, upon the tunneling dynamics of a pure condensate at zero temperature confined in an double well potential like.

Bauru is considered an important city in the regional context of the São Paulo State. It is situated in the center-west of the state and its main economical activity is the service sector. The urban growth of Bauru has occurred in the bottom of the valley and that compromised the ecological condition in the urban mean. Also known as the "city without limits", Bauru has been suffering with the public politics of the city government, associated with the conditions of the urban environment appropriations, the financial capital and real state, besides the irregular use of the urban soil, all this contributing to accentuate the unbalance of the physical nature, the landscape and the social conditions of the inhabitants that live in areas situated in the bottom of the valley. The purpose of this research is to identify and to analyse the importance of the Special Sectors of Conservation of the Bottom of the Valley also called SEC in the urban system and in the maintenance of life quality to local communities. In this investigation, we used and analysed the laws established by the Town's Plan, in order to check the execution of the environment legislation about the occupation of urban space in the areas of the bottom of the valley. It was observed that the social environment degradation in the Special Sectors of Conservation of the Bottom of the Valley SEC in Bauru has became evident, this meaning that the urban environment is in crisis and it is risky for the ecosystem capacity. It was also verified that the growth of the city has been orientated to the appropriation of the urban space, without considering the social and the natural aspects of the environment, resulting in fragmented actions and in the wasteful of public resources. The public practices of Bauru local administration does not accomplish the legislation in effect by the Town's Plan, risking the proper development of the city when avoiding the environment problem in the Special Sectors of Conservation in the Bottom of the Valley. The urban expansion growth to new areas made that the bottom of the valley could express how are the relations between the public power and the different kinds of interests established in the urban environment, making the Special Sectors of Bottom of the Valley objects to be used to a few people, in detriment of the most of the population, that live in helpless situation, contributing to accelerate the degradation of the social-environment process. This work has the intention to be helpful for the comprehension of the physical nature relations in Bauru urban environment and to add support as to make it easier to the local government to direct its actions to a democratic administration concerning to the city urban expansion.

In this work, we have studied the behavior of the line H*(T) in filamentary samples of BSCCO, which were grown by the LFZ technique, Laser Floating Zone. Previously studied in other specimens prepared by specific routes for exemple, samples of Mgdeficient MgB2; YBCO prepared by the Sol-Gel technique; or polycrystalline samples of Nb the H*(T) frontier defines the region in the magnetic fase diagram above which the intergranular critical current density vanishes. The H*(T) line is an extrinsic feature, dependent on the preparation and subsequent heat treatment of the samples, observed only in specimens having a narrow intergranular critical current distribution, which can be obtained controlling properties such as granularity. Measurements of ac-susceptibility as a function of temperature has been performed, for different values of the magnetic excitation field, from which a point was determined, T*, above which the ac-susceptibility is independent of the intensity of the magnetic excitation field. This means that, above T*, only the intrafilamentary regions are able to transport supercurrents. Relating the magnetic measurements with results of transport measurements four terminals and flux transformer we have found a complete similarity between T* and the offset critical temperature, Tc off. We have also verified that T* depends on the field H, so that the magnetic phase diagram includes an extrinsic frontier H*(T), confirming the original expectation that the intergranular space surrounding the grains of a system with controlled granularity, may constitute an efficient set of pinning centers for magnetic flux, what occurs, in fact, in the region to which H*(T) is an upper bound, where the intergranular critical currents are nonzero. It is quite impressive that different samples present practically coincident H*(T) frontiers, what reinforces the prediction that the studied line has a universal character, as long as the sample fulfills the criterion of exhibiting a narrow intergranular critical current distribution.

The Practical of Education, as integrating disciplines between the specific knowledge of Sciences and the pedagogical knowledge for the teaching exercise have become the locus of the quarrel about educational formation. In this work we present the results of a research carried through a project of intervention, made with Chemistry studensts, based in the Investigative Methodology, in the development of the discipline Practical of Chemical Education I and II, at the Universidade Federal de São Carlos. The objective of this research was to search the perceptions of the students about their own learning and its transference to other contexts, useing the referencial considered by the Fenomenology and by Social Semiotic for data analysis. This analysis confirms the potential of the methodology proposal in the metacognitive development of the students and indicates a process in their conceptions. Gradually they perceive the construction of learning strategies as a process of personal construction. On the other hand, a valuation of this construction occurs as professional knowledge that needs to be developed in the pupils through the performance of the teacher (transference to other contexts and applicability of the knowledge). The reflection propitiated for the students took them to recognize the complementarity between teaching and learning, becoming both unassociable.The pupils were capable to construct and to reconstruct the meaning of learn with the final point in the perception of the responsibility for the own process of learning and in the necessity of applying these knowledge in new contexts, including the professional activity.

The diet is an essential factor for the growth and maintenance of vital functions as well as to ability fish to reply the stressors. The reduction of oxygen concentration in the water may occur mainly in fish culture ponds, and may reduce the growth rate of the animals due to metabolism changes. Therefore the supplementation of the diet with copper and vitamin E can improve the animals defenses. Matrinxã specimens, Brycon cephalus, promising specie for fisheries, were fed with commercial ration (Co) and rations supplemented with vitamin E (E) and vitamin E+copper (E+Cu) during 30 days following by exposure to hypoxia (Hpx) during 24h (DO = 2,87 mgO2/L). The hematological variables [hematocrit (Hct), hemoglobin concentration ([Hb]), red blood cells (RBC), mean corpuscular volume (MCV), mean hemoglobin concentration (MHC) and mean corpuscular hemoglobin concentratrion (MCHC)]; metabolic changes such as concentrations of glucose, lactate, piruvate, ammonia, glycogen and protein in liver, red and white muscles and plasma (exception of glycogen) and, the oxidative stress parameters as concentration of peroxide lipids (HP), activity of superoxide dismutase (SOD), glutathione peroxidase (GHS-Px) and catalase (CAT) (exception in plasma) in the same tissues, including the gills and heart. The diets E and E+Cu may increase the aerobic capability of matrinxã when in hypoxic condition as there were increases of [Hb] and MCHC in group E+Cu and an increase in MCHC in E accompanied by an increase in the pyruvate and no change in lactate in most of tissues of fish fed wit supplemented diets. These results support the view that the both supplemented diets, and mainly the E+Cu, seem to increased the aerobic capacity of matrinxã during hypoxia. Hypoxia increased HP concentration only in the plasma and the supplemented diet change the oxidative stress, hematological and metabolical parameters. The diet E reduced HP concentration in the heart and red muscles during hypoxia and the diet E+Cu increased the enzyme concentration and activity without generated HP increase, even in conditions of higher aerobic metabolism. The obtained results suggest that the supplemented diets increased the aerobic capacity of matrinxã during hypoxia without increasing oxidative stress, while the metabolic adjustments front to the reduced concentration of O2 had been efficient to maintain the O2 delivery to the tissues since the hypoxia only modified the parameters analyzed when in association with the differentiated diets.

In this work, we consider the use of Meta-analysis with a Bayesian approach. Meta-analysis is a statistical technique that combines the results of di¤erent independent studies with purpose to find general conclusions. This term was introduced by Glass (1976) and it has been used when the number of studies about some research project is small. Usually, the models for Meta-analysis assume a large number of parameters and the Bayesian approach using MCMC (Markov Chain Monte Carlo) methods is a good alternative to combine information of independent studies, to obtain accutrate inferences about a specified treatment. As illustration, we consider real medical data sets on di¤erent studies, in which, we consider fixed and random e¤ects models. We also assume mixture of normal distributions for the error of the models. Another application is considered with educational data.

The general purpose of this work is the optimization of the conducting polymer deposition on RVC and the use of these electrodes in an allpolymeric ion-lithium battery, which means an anode and a cathode made of conducting polymers. Several steps were done in order to attain this purpose: i) a previous study on the effect of different pre-treatments on the RVC surface; ii) the optimization of the deposition (chemical or electrochemical) procedures of conducting polymers on RVC; iii) the investigation of the influence of different kinds of deposition on the properties of the conducting polymers; iv) the study about the effect of different dopants on the electrochemical and morphological properties of the polymers; and v) the verification of the electrode performance as anode or cathode in an ion-lithium battery. The results lead to the conclusion that the ohmic drop effects and low current penetration, a characteristic of the tridimensional RVC electrodes, can be minimized by using thinner electrodes, which is crucial specially for conducting polymer films obtained by electropolymerization. The high surface area of these materials influenced positively on the electrochemical behavior of the electrodes, leading to high-specific capacity electrodes when compared to similar bidimensional electrodes. However, to enable the investigation of these electrodes by Electrochemical Impedance Spectroscopy, the proposition of a new equivalent electrical circuit was done considering two different electrochemical environments (at the inner and outer substrate surfaces). Chargedischarge tests for batteries using RVC/polymer electrodes as the cathodic material showed similar or even higher specific capacities than the ones found in the literature. It is believed that the substrate s high surface area is the responsible for these findings, since it facilitates the redox reactions in the polymers.

This study analyses 10 to 12 year-old children, 4th grade students, teenagers between 13 and 15 and students belonging to the 7th grade fundamental teaching experiences related to the aggression and violence in school environment and their perceptions about these experiences. The research was conducted during the school period of 2004 in a fundamental teaching unit located in São José do Rio Preto - SP, aiming to investigate if the aggression among students may cause the will of not going to school, as well as if the aggressions which are responsible for lacking of discipline interfere on the teaching-learning process development. In the first chapter of this work we have written about the contemporary view related to the agressions in school. European and some Latin-American authors have given support as a theoretical referential in this chapter. After that, we have sent the Brazilian production, which has as a theoretical reference master and doctor ship thesis. On the second chapter we have written about the researchs, the work, methods, the context, the partakers, the place where the field research was conducted, the used instruments for collecting and analyzing data. In the third chapter, we have mentioned the research results. At last, on the fourth chapter, we have gathered the arguing and final considerations. The mentioned experience s analysis conducted by the research individuals have indicated that the aggression acts and violence in school environment have points in common and points that are different when dealing with children and teenagers which can be linked, among other, to the characterists belonging to the different stage. It s been observed in this study that there s a major involvement in physical aggressions from students who come from 4th grades and a major participation of students from 7th grades relating to psychological aggressions. The classroom is considered as a place where the aggression acts are most common among students. It has been observed in analyzing the teachers and staff points of view concerning to the school violence that teachers consider the familiar context the most responsible element in the aggressive behavior of the students; on the other side, the two employees notices aggressions taken on the courtyard by vain reasons and jokes badly conducted.

The purpose of the present study was to evaluate the effects of physiotherapeutic intervention on the autonomic control of heart rate through heart rate variability (HRV) indices at rest (supine and seated positions), during deep breath test (DBT), during an exercise protocol and during walking, in patients with acute myocardial infarction (AMI) submitted to phase I of cardiac rehabilitation. Second, evaluate the effects of an inspiratory muscle training (IMT) on the maximal inspiratory pressure (PImax) and on the magnitude of respiratory sinus arrhythmia (RSA). Initially, thirty five patients of both genders were studied in the 1st stage of the cardiovascular physiotherapy (CPT), however, only eighteen of them performed all six stages of treatment (mean = 56± 13 year). These patients, who were admitted to the Coronary Care Unit (CCU) (two days) and the ward (four days) of the Santa Casa de Misericórdia de São Carlos with noncomplicated AMI, were hemodynamically stable and used conventional medications. The 1st stage was initiated 22± 5 hours after the CCU admission and the progression to other 5 stages was done based in the daily clinical evolution of each patient. This stage included 10 minutes of rest (pre and post-exercise protocol), 4 minutes of deep breathing test and 5 minutes of exercise protocol (active-assisted low extremities exercises) in the supine position. Furthermore, the 6th stage included 10 minutes of rest in the supine position (pre and post-intervention), 4 minutes of deep breathing test, 5 minutes of rest in the seated position (pre and post-intervention), 5 minutes of active low extremities exercises in the orthostatic position and 15 minutes of walking. The instantaneous heart rate (HR) and the R-R interval (RRi) were acquired by a HR monitor (Polar S810) during all stage and the blood pressure (BP) was measured before and after each stage. Additionally, the PImax was measured (in the seated position) through a manuvacuometer at the pre and post-IMT, which was performed at the 2nd to 6th stages. The intensity of IMT was settled at 40% of PImax pressure load. The HRV was analyzed by time (RMSSD and RMSM indices) and frequency (Fast Fourier Transform) domain methods. The power spectral density was expressed as normalized units (nu) at low (LF) and high (HF) frequencies, and as the LF/HF. Results: The cumulative effect of physiotherapeutic intervention caused increase of AFnu (p<0.05) and decrease of LFnu (p<0.05) when they were evaluated at the rest pre-intervention in the supine position and during exercise protocol of 1st and 6th stages. Additionally, decreased LF/HF was also observed at rest pre-intervention in the supine position. However, no changes were observed for these indices when the 1st and 6th stages were compared to during the RSA, in the rest post-intervention (supine position) and in the rest pre and post-intervention (seated position), and the 4th and 6th stages were compared to during the walking. In the time domain, RMSM and RMSSD diminished at 1st to 6th stages for rest post-intervention in supine position. The IMT augmented the PImax in 46% (P<0.05), but increased PImax and the RSA magnitude did not correlate among them. Conclusion: The CPT realized in the phase I of the cardiac rehabilitation caused increase in the vagal activity and decrease the sympathetic activity during rest and exercises conditions, since the beta-blockade and IECA medications dosages were not altered. Additionally, the intensity used in the IMT was able to improve the PImax, but it did not influence on the RSA magnitude. Financial support: FAPESP (04/05788-6) and CNPq (478799/2003-9).

The aim of this study was to set up and evaluate an intervention program, based on the manufacture of dolls, with children victims of violence, living in a shelter and presenting learning difficulties. The study aimed also at describing the needs and skills of these children during the proposed activities and their evolution throughout the program. Three children aged seven, eight and nine years, attending the classes of the 1st, 2nd and 3rd grades took part in the program. Doll manufacture involved specific steps so that systematization (patterning) of situations could be assured. Specific strategies were adopted in order to offer opportunities of successful experiences in the tasks performed by the children. The program consisted of 20 hours of intervention, divided in nine videotaped sections. The Silver Drawing Test, applied pre and post-intervention, was used to evaluate the results. To analyze videotape records, an observation guide, previously adapted from clinic observation guide of children, was used. The observation guide allowed systematization of each individual observation, with focus on quantitative performance indexes, by means of production and behavior, facing an oriented situation. Data were analyzed intraperson and results were evaluated to detect possible influences of the program on children performance. pre- and post-intervention SDT indicate differences in child performances. Such differences must be analyzed under the specific context of the program, considering the evolution of behavior and performance, and taking into account the stage of development of each child. In conclusion the program: allowed children an exercise of abilities and a gradual development of autonomy, distinguished the development of initiative attitudes; it supplied chances of organized communication and possibilities affective entailing with the evolution of positive interactions between child and adult; it made possible acquisition and maintenance of attitudes of organization; it allowed the continuous exercise of the planning ability; and the increase on feelings of self-valuation. The program may be used as an instrument to evaluate the presence or absence of the resources necessary to child development, as well to identify areas that must be priority within a stimulation context. A gap to be filled by further research is studies that draw attention to the care of victimized and sheltered children, aiming at overcoming the problems generated by violence, maximizing children internal resources to struggling and raising the factors of protection that provide them with proper self-control when facing risk situations.

Contrary to what is known as process-product researches, in which teachers used to be seen as a mere technical performer, nowadays the teacher is the centerpiece in the educational process. In this new approach, the teacher is the core of the debates and professional practices, personal life and know-how of the professional practices are analysed. Lee Shulman is one of the researchers who tries to make a list of required knowledge for a teacher to carry out his/her job. This list is referred to as knowledge base of teaching by the author, which is formed, mainly, by content knowledge, general pedagogical knowledge and pedagogical content knowledge. As one of the sources to acquire such knowledge is the everyday practice, we have asked in which aspects and how a veteran teacher and a teacher-to-be, working together in their development process, and having a training teacher as mediator, can share the required knowledge in teaching. Two professionals graduated in Education and the researcher, in the role of mediator, took part in this study. One of the professionals, referred to as teacher-to-be, had no classroom practice; the other, referred to as veteran teacher, had an eighteen-year-long experience. Data was gathered from August through December 2003. The focal point was the elaboration, implementation and reflection about a series of five classes taught to early grades in Elementary School, the subject being air . The focus was the knowledge that is part of the knowledge base of teaching pointed out by Shulman. Results showed that the teacher-to-be faced the same difficulties and experienced similar tensions and anxiety as her veteran peer when at the beginning of her career. However, after years of practice, the veteran teacher seemed to have solid techniques or strategies on how to deal with students, differently from the teacher-to-be, who still tried to build them up by a process of trial and error. The greatest interaction between them was about the general pedagogical knowledge , when they talked about strategies to control students discipline, their characteristics and their behavior during classes. Both presented an important lack of content knowledge , which made it difficult for them to understand each other when that was the point. They had different motivation concerning the focus of analyses of the classes and about what they wanted to learn: the teacher-to-be focused on her own performance while the veteran teacher looked at the learning process by the students. Such fact might show that, instead of helping the development process, the longer the practice the more difficult for the peers to interact since the teachers interests could be different. Accepting an opinion or idea from a peer seems to be tied more to private characteristics of those involved. Contrary to what was expected, i.e., that the teacher-to-be could learn more about how to teach from the veteran teacher, there was learning by both professionals and an improvement in their knowledge base of teaching .

This research is related to the influence of Teaching of History to build the sense of embrace their ethnic-racial roots and the relation between blacks and whites. It has participated in this research four former black students of an Affirmative Action project who took place in the city of Sao Carlos, state of Sao Paulo, which aimed to prepare students to College admission exams. This research was performed and guided by the following research inquiry: Does the teaching of History contribute to the affirmation/denial to the ethnic-racial feeling of poor black students in the college admission courses? The study takes off from the observations made by the researcher in charge for the subjects of History and Geography in this project. He aimed to verify whether the teaching of History interferes in the self esteem and identity of afro-descendants students, leading them to the feeling of denying their own ethnic racial roots, which is fabricated in the society. Systematic talks with two former female students and two male students were conducted involved in the Affirmative action project that was developed in the period of 2002 and 2003, sponsored by Fundação Ford and attached to Department of Physics of USP, campus Sao Carlos Sao Paulo, aiming to facilitate the access and permanence of poor black students at the public university. It also aimed to strike back situations of prejudice, discrimination and racism such ideas reinforced by ideologies still present along the years in Brazil. The findings showed that the integration of the researched students favored them to embrace the feeling of ethnic and racial roots to what they were alike, when they identify themselves as afro-descendants. These students dealt with racist attitudes and discriminations in their routine. However, they got their self esteem and identity favored by the time they recognized themselves as culture makers and active agents in the scenery of the Brazilian history.
