This work studied the anaerobic horizontal reactor of fixed bed (RAHLF)for treatment of waste waters, developed in the Department of Hydraulics and Sanitation of the School of Engineering of São Carlos USP by investigating some mathematical models with two different RAHLFs conditions in different scales: the first in pilot scale by treating domestic and other in bench scale by treating synthetic substratum. The pseudo-homogeneous and heterogeneous models were investigated by considering or not the substratum dispersion in the axial direction. The models were resolved numerically by fourth order Runge-Kutta method, orthogonal collocation and finite differences. The values were compared to reactor experimental values. In the pseudo-homogeneous resolution model with dispersion by using the reactor data in pilot scale was adjusted the axial dispersion coefficient to 1,65.10-3 m2.s-1, after that was used in the solution of the heterogeneous model. The benches reactor values were used to obtain the dispersion coefficient as Zero. The parameter kinetic variation in the reactor was investigated by verifying that this variation is not responsible for the difference between the experimental data and those previewed by the model.

The extracellular polysaccharides (EPS) excreted by algae comprise an important fraction of organic matter produced by the phytoplankton in fresh and salt waters. Thus EPS can be considered an important organic carbon source for microorganisms, besides their possible contribution for humic compounds formation. In this context, this study aimed to describe the seasonal variation of dissolved organic matter (DOM) heterotrophy in function of limnological variables of the Barra Bonita reservoir (Brazil, SP) and to quantify the transfers of dissolved organic carbon (DOC) from the EPS to microorganisms, mineralization and humic substances formation. It was verified the rise of mineralization potentials (aerobic and anaerobic) during spring (September to November) and summer (from December to February). It was also verified that in drier and colder months (July and August) the mineralization processes involved more oxygen consumption per carbon mineralized, that is to say, occurred a rise of O/C stoichiometry values. Statistical analyses between heterotrophy potentials and limnological variables revealed that heterotrophy potentials (aerobic and anaerobic) were basically linked to DOC contents in the water. A kinetic model was developed aiming to describe the decomposition of EPS from different algae species and it allowed us to establish a general tendency for the fates of EPS when they are submitted to decomposition in reservoir water. The results showed that about 4.0 % of the DOC from the EPS was transferred to humic substances; 23.0 % was mineralized after formation of microorganisms (by their decomposition) and approximately 73.5 % was mineralized by catabolic processes.

The aim of this study is to identify the inter-relationships established between teachers and 4th grade fundamental school pupils families that have learning difficulties and attend to parallel reinforcement classes. Took part in this study five regular 4th grade teachers, four parallel reinforcement classes teachers and six families (three of which were considered to be involved with the school and three non-involved). All children had learning difficulties and attended classes at three public schools in the town of Jaboticabal, São Paulo state, in Brazil. The instruments used for data collection were semi-structured interviews and parents evenings. The results show that the families evaluate negatively the current relationship with their children s school and point out that they would like to participate more actively, getting to know more about their children and the school as a whole. However, they see positively the school participation towards their families. The families in the study differ from the traditional mom-dad-children type of family seen as correct and normal by the teachers. The mothers in the study tend to follow the school life of their children, check their notebooks daily, ask how was the day at school and help with the homework. On the other hand, teachers judge the families as not structured and responsible for the students failures. They consider that the families oversight and are uninterested toward their children education. Teachers see their and the school s current involvement with the families as very positive, but not the other way round (they see as poor the family-school involvement). During the study it was possible to notice that the family-school communication is done mainly through notes and in the parents evenings every other month. A closer contact may happen between parents and teachers if a student eventually appears to have learning difficulties or misbehaves. It was possible to verify that the contacts are always the schools initiative and are always restrict and punctual. The families participation is restricted to the rules dictated by the school. It is the school that decides how, when and why the families should take part in the school environment. In the teachers speeches the parents-school partnership is put in evidence but there is no apparent effort from the school stimulating the parents participation in order to improve their children s performance in the same way that there is no coordinated effort to make parents act in partnership with the school.

This research had as the subject matter, the use of the game with movement as assistance on school teaching. The approach of the subject-matter at issue, required a series of inquiries and considerations about the situation that involves it, once it was not considered relevant to analyze a teaching assistance, without considering all the problems surrounding it. If we observe the classrooms and the school spaces, we are probably going to find speeches on the educational purposes that look for graduating students able to search and accomplish knowledge, and also students who are critical, creative, conscious and social transformers. We are also probably going to deal with educational practices not suitable to such projects and that lead the student, several times, to the passivity, immobility and lack of reflection. In the face of this situation, the present study, that was done in the form of research-intervention, proposed to search by means of games with movement, to develop a part of the school content of the elementary school, focusing on games that explore the body movement and utilizing other school spaces beyond the classroom. Such games were prioritized because we judge that the motor experiences can assist the cognitive development and the development of abilities necessary to the learning process of children. Thus learning as Demerval Saviani, Álvaro Vieira Pinto and other education studious that the main role of the school is to socialize the elaborate knowledge and the acquisition of the instruments, like reading and writing, which make it possible to access and dominate a group of knowledge, this research study tried to methodize on the following issue: Is it possible to use games with movement as auxiliary instruments to teach subject contents related to the curriculum of the elementary school? In order to answer this question, it was necessary, however, to look for answers to other two main inquiries: How are the educational games with movements understood by the teachers and how are they used, in order to serve as teaching instruments of the school contents of the elementary school? The results made clear that the educational game with movement can be a great associated to the teacher's practice, providing a better atmosphere for the teaching, a didactic situation, which can intermediate students and the acquisition of school contents by communicating the school knowledge in an attractive way, in order to make it interesting for the student, as well as by assisting the assimilation and systematization processes of it. However, in order to obtain that, the teacher needs when using it, to develop an auto-reflexive process, dedicating his/her conscious attention to what is being taught (content) and how it is being taught (way), in order to obtain the game as an educational source, to rescue the pleasure and happiness on learning that it can provide. It also seemed to be necessary, for instance, to take care related to the atmosphere established among the teacher and the students and to the kind of participation and involvement of them, during the games with movements, as well as the degree of difficulties established by the rules and purposes and in the face of the school contents focused, in order to get promising results with the above-mentioned teaching instrument.

The simpler screening tests applied to detect disease instead of the more elaborated, usually result in the risk of incorrect diagnostic. However, these tests are only useful when the risks of misclassifications are known and considered acceptably low. So, with the purpose of looking for information on the proprieties of screening tests, as well as measuring their error rates, a Bayesian procedure was formulated using a simulation technique (Gibbs Sampling with latent variables) for estimation of the parameters of interest in the absence of a gold standard. Two applications to real data have been explored. The first one refers to the detection of the infection caused by the strongyloides parasite on 162 refugees from Cambodia that arrived in Montreal, Canada, between July 1982 to February 1983, using data from serologic test and stool examination. The second one has the purpose detecting the obesity rates on males and females school pupils through the information supplied by the anthropometric Must and Cole criteria.

Diatoms are amongst the most representative groups of algae in periphytic communities. There is evidence that epilithic diatom assemblages are good indicators of environmental condition since species composition and population abundances change in a more or less predictable way due to pollution or contamination of surrounding waters. The present study investigated limnological characteristics of the Gravataí River, RS, Brazil, following, in the course of two seasons, variations of physical, chemical and biological variables, between September 2000 and August 2002. Spatial and temporal changes in the structure and diversity of epilithic diatom communities were studied in order to be applied as water quality indicators. Sampling of epilithic diatoms from stones used as artificial substrates were carried out every three months, in six sites along the river. Climatic, hydrological physical and chemical variables were simultaneously analyzed. A marked seasonal variability was observed regardig both climate and hydrology. Seasonal variation in temperature was wide, with a range of 20°C between summer and winter seasons and a one order of magnitude variation in river discharge. The results evidenced that Gravataí River has two distinct portions, the Upper-Middle stretch, oligotrophic, oligo-mesosaprobic, being placed in Class 1 or 2 regarding, water uses according to CONAMA classification and the Low Stretch , meso-eutrophic, meso-polisaprobic, Class 2, 3 and 4. There is a gradient descontinuity in the Middle course caused by the discharge of heavily polluted residual waters from Porto Alegre city, resulting on increments of labile organic matter and increase of 3 to 50 times on DBO and faecal coliforms, respectively. A total of 169 taxons were recorded in the epilithic diatom assemblages of Gravataí River during the studied period. The species Cocconeis placentula, Achnanthes sp, Selllaphora seminulum and Eolimna minima were particularly abundant in the autumn, whereas Gomphonema parvulum, Eunotia pectinalis and Navicula radiosa reached the highest densities in the winter. It was also observed that Nitzschia palea and Sellaphora seminulum became gradually dominant and constant species in the Low stretch of the river, for being more tolerant to pollution. The use of a biotic index considering both environmental variables and the relative abundances of species, combined as indicative values, well represented the gradient and temporam changes observed..Comparing these indices with those calculated using the Regional Water Quality Index available from literature gave very similar values evidenced that the model might adequately describe the water quality in the rivers of Rio Grande do Sul.

The teaching democraticalization by Federal Constitution of 1988 and the National Education Basis and Guidelined Law 9394/96, provided opportunity of teaching for all and intensified the need of educational system changes for better theaching quality. Aiming to reduce the school failure, the public politics for education have been prodigal in the variety of alfabetization, assessment, recovering of the not-understood contents end even school physical space use programs. The teacher s capacitation became a Education s Ministry preocupation, so was stablished in 2001 the PROFA Programa de Formação de Professores Alfabetizadores (Program of Formation Alphabet Teachers) with assistence of the municipal teaching system. Bringing a course of didactics contents and procedures improvement with a theoric base settled in a vast bibliography with psychologist and socialist character, this program had as the initial purpose to guide the teachers and to contribute for the development of their abilities in the alphabet process. However, would the PROFA s purposes change the teacher s practice, and improved the children apprenticeship? The answer for this was seeked by developing a case study with a qualitative investigation aiming to know entirely the PROFA, to mark each proposal stage, to follow the application of activities in fundamental school classrooms as well the children development and aprenticeship. Associating a bibliography study, a documental analysis, interviews and participant comment, was following during the year of 2002 the classroom s activities of teachers from first stage of Coronel Tobias Fundamental Education Municipal School in Descalvado SP. The methodological directions application of the PROFA provided a children progress on reading, hand-writing and oral interpretation, and text production, but not enaigh for all of them take the same profit during the year. Also the subsidies given by the PROFA were accepted and applied by the teachers at the daily activities school. Was concluded that it is important the need of the evaluation of paradigms of Formation that provides the preparation of teachers more reflexive and committed with education to incorporate effectiveness the contents didactic-methodologicals given by the Program like this in the daily pratice professional of the educators. As well efficient public politics, the pedagogic promises of all professional in this area is very important to get education improvement, including the commitment between teachers, co-ordenators, supervisors and director of the school. Is not possible to change it if the educators save efforts to get it done, they must play their role in this process.

The present study considers the possibilities and the limits of a school Principal s work in a daily routine of a state high school. By identifing the dificulties found by school Principal attemps to the abilities that should be improved to face them, once the school main objetive is the student s development as a person and his preparation to a qualified work as a citizen. A case study was undertaken in a state high school in a countryside town of São Paulo state. Among the Principal s work possibilities stand out the availability of teachers who are officially hired full time job in the school; the acess and the proximity the Region Educational Direction; the school area. The limits stand out the lack of the school historical contest valorization; the presence of bureaucratic structure, the relation with the system that imposes some determinations without considering peculiarities, the absence of a pedagogic proposal and the violence. The school Principal should improve abilities of working with a group participation, to assign tasks, to be creative, dynamic and able to searche for alternatives to the reality he works with; to think about his actions in order to achieve coherence between practice and theory.

In the present research, 116 specimens of Hoplias sp. (Erythrinidae: Characiformes) from Grande river basin, São Paulo state (Alto-Paraná basin) were morphologically analyzed. They are all representants of malabaricus group , which can be distinguished of lacerdae group mainly by the shape of dentary region, and the number of pores in each dentary. From each fish analyzed, it was obtained 24 meristic and 33 morphometric data. The osteological analysis was realized in four exemplars of Pardo river basin. In the studied sample, it was found two different species, and they are sympatric in the majority of localities. These results corroborate with cytogenetic studies, which demonstrated two different citotypes in Grande river basin. This way, a description was realized for the species, that in this work are named Hoplias sp. A and Hoplias sp. B. They can be distinguished one from another by a combination of characteristics, mainly the shape and the number of teeth in the accessory ectopterigoid and the proportions and distribution of infraorbitals. Morphological differentiation among them was analyzed by the principal component analysis, and the results indicate differences in body form.

Deleuze: do pensamento trágico à nova imagem do pensamento em Nietzsche

Sousa, Péricles Pereira de
;
Ferraz Júnior, Bento Prado de Almeida
This study aims at following Deleuzes s reflections about Nietzsche, assuming as the reading object the book Nietzsche and the Philosophy (1962). From the first pages, Deleuze asserts that Nietzsche is responsible for inscribing in the History of Philosophy a new image of thinking, consonant with a new image of the philosopher. Especially on the third chapter, this idea gains profundity, for Deleuze not only discovers in Nietzsche a project of critical nature but also turns it against Kant. In a few words, Deleuze believes to find in Nietzsche s Genealogy of Moral a sort of answer to the Critique of Pure Reason, since Kant did not manage to carry out his critical undertaking fully, for not having considered the problems in terms of values. Nietzsche is the major responsible for such feat. To Deleuze, the Kantian critique is just a caricature of the real critique. Although these are the most important ideas, Deleuze was followed as a whole, trying to keep the attention to the whole of his reflections in the most important chapters for this essay. In short, it is about a flight which starts with the tragic thinking and ends in the critique.

Les représentations sociales des professeurs sur le corps humain et ses répercussions dans l enseignement de Sciences Naturelles, constituent un étude dans la perspective moscovicienne. En reférence à une sorte de connaissance socialement élaborée et partagé, un sabor pratique qui dévoile des valeurs, croyances afectivités, symboles, certitudes et interprétations, sur un objet donné et qui a comme fonction première, orienter des communications et des conduites. Cette recherche propose accèder aux représentations sociales, des ces professerus-là, sur le corps humain mettant en rapport les contextes de leur formation, de leu contenu constitué et de l articulation avec la pratique pédagogique. 108 professeurs de Sciences Naturelles dans l enseignement publique du 1o cicle à Uberlândia ont été observés. Les donnés ont été obtnus à partir d association livre des mots, de triage hiérarchisés sucessives et interviews semi-structurés.Lés térmoignages recuellis ont été soumis à l analyse de contenu Bardin (1977), sous forme de statistique et a rendu possible la délimitation de classes sémantique. Le contenu des discours obtenus à partir des interviews a été classé en catégories et ont permis l accès critique au sens des comunications, son contenu expries ou implicite. Le corp humain y est compris sous le paradgme de la corporéité, que le considére comme um tout, indissociable, irréductible qui manifest toutes les possiblités de l homme dans son intégralité. Les analyses realisées ont pu constater que les représentations sociales sur le corps humain dans le groupe des professeurs ont été centrés autours d un noyau central qui met en valeur les éléments de nature biologique cependant, colorés des nuances périphériques d ordres sociales, culturelles, afectives, psichologiques. Au niveau individuel elles s organisent dans un noyau central qui met en relief des éléments de dimensions de mêmes caracteristiques, mélangés toutefois aux éléments d ordre biologique. Ces constations entraîntent la necessité de repenser l enseignement par rapport le corps humain, en classes de Sciences Naturelles. Il faut contempler le corps, pendant que expression de la nature humaine, dans unce perspective holistique, comme un grande système d interaction. Il faut que le professeur ait conscience et considére de façon plus critique ses propers représentations, pour que sés concepts ne soyent plus jamais présentés, comme si le corps humain fût fragmenté, morcelé, dissocié même du monde. Les représentations sociales et leus implications sur la pratique pédagogique ici recherchées, fournissent des subsides significatifs pour des changements precieux au jour à jour de l enseignant. Ce qui est souhaitable quand on désire promouvoir une meilleure qualité à apprentissage de Sciences Naturelles.

This study is inserted in the ambit of the researches that investigate the discussion and comprehension of the process of teaching professional learning. It has how a reference the qualitative approaches of investigation and intends to answer this question: How is defined the learning of teaching in a Professorship course medium level through experiences lived in the Supervised Training ship and Teaching Practice? In order to realize this it was used a study of case, for what it was selected under determined criteria, a third grade professorship course student from the Centro Específico de Formação e Aperfeiçoamento do Magistério CEFAM Deputado Miguel Petrilli, located in the city of São Carlos, SP. The theoretical reference in what is based the research, defends the idea that the learning of teaching is a continued process. It still sustains the existence of the relationship between the actuation and the professor thought, between the acquired learning by living and the idiosyncratic teaching way. It sees in the reflection the possibility of interrelate the thinking and the acting. The inquiry had used information from: reports, semi-structured interviews, classes regency, classes observations. The collected data allow locating institutions, persons, and contexts that have contributed to constitute some of the teaching participant conceptions, the learning, and teaching itself. The information also reveal the learning resultant from the teaching practice, seeking to reflect about the relationships between thinking and acting. Finally, the possibilities and the limits of initiatory formation are discussed for the learning of teaching.

The aim of this work was to investigate the influence of body posture during reaching movements in four healthy, four-month-old infants. Experimental conditions consisted of presenting two toys alternately, at the infant s midline and shoulder levels and midway between the infant s shoulder and wrist. After the reaching, the toy was taken away and given back again for a period of two minutes (for each toy) or until the infant reached for it a total of ten times. This procedure was repeated at the supine posture (0º), a reclined posture (45º) and a sitting posture (70º). We randomized this order these positions. The results were recorded on video and analyzed using the Dvideow system for the purpose of checking the kinematics of the angle of the shoulder (flexion/extension and abduction/aduction) and elbow flexion/extension). Also, we analyzed the rectitude index (the distance traveled by the hand during a reaching movement divided by the distance between the starting and the end points), time (in seconds) in each of the three positions, as well as the frequency of reaching unimanually and bimanually. The statistical method used for the rectitude index was t-Student test and for the frequency of reaching was the analysis of variance (ANOVA). From the results showed that there were differences between the frequency of reaching unimanually and bimanually (p-value=0,0341) in sitting posture. The frequency of reaching was more in sitting posture than in supine posture. In relation to the rectitude index, the test showed a significant difference between the supine and reclined postures (p-value=0,001) and the supine and sitting postures (p-value=0,001). The infants spent the same time reaching in the tree postures. When analyzing the angles, only two babies used the same movement pattern for the three positions. We concluded that, the age of 4 months, reaching does not follow a stable pattern, which can be modified by the position of the infant. Each infant has its own intrinsic dynamics and reacts in different ways to the environmental restrictions imposed by different body positions.

The Low Intensity Laser Therapy (LILT) constitutes one of the resources most used by physical therapists, with the goal of stimulating the process of repairing the skeleton muscle tissue. On the other hand, the intense utilization, its respective action mechanisms and therapeutic effectiveness are not scientifically proved. Based on this, we elaborated the present study aiming to investigate the influence of the LILT, at wavelengths (λ) usually used at clinical practices (670, 685 and 830 nm), on the function of the Myogenic Precursor Cells (MPCs), directly responsible for the tissue regeneration process. The beginning phase was carried out throughout in vitro experiments, determining the alterations started by radiations over the proliferation ability and the cellular differentiation. The MPCs used were in the second passage, after had been extracted from four days old Wistar rats. To analyze the proliferation, it was elaborated, for each λ, a dose-response data curve including the control group constituted of non-radiated cells, and the irradiated groups with doses of 0.3; 0.6; 0.9; 1.2; and 1.5 J/cm2. This procedure was carried out with the cells under the influence of 5 or 10% of fetal bovine serum (FBS). The dose demonstrating the highest effectiveness on the cellular proliferation in each radiation, was used to establish the influence on the process of cellular differentiation, and investigated throughout the analysis of the expression of the genes related to the isoforms IIa and IIx of the myosin heavy chain (MHC). The final phase of the study was pointed towards the radiation action evaluation, at the same dose parameters used before, on the muscle regeneration process in vivo, after induced cryoscopy lesion at the Tibialis anterior muscles of adults Wistar rats. There were evaluations of the histological, histochemical aspects for the Succinic Dehydrogenase enzyme (SDH) and the activity of the Lactate Dehydrogenase enzymes (LDH) and Citrate Sintase (CS). The outcomes demonstrated that the radiation at λ of 670, 685 and 830 nm promoted an increase of 56.8, 70.6 and 84.8 % on the proliferate ability of the PMCs. These values were achieved with the 1.2, 0.6 and 0.3 J/cm2 doses respectively, and with the cells under the influence of 5% of FBS. The highest concentration of serum (10% of FBS) determined a less pronounced bio-stimulating effect, rising only 13.6, 17.5 and 10.9 %, respectively. In relation to the MHC isoforms expression rate, it showed that there was a significant fall of the IIa isoform, due to the action of the 685 nm, and an increase of the IIx isoform, due to the action of the 685 and 830 nm radiations, in relation to the non-radiated cells rate. By means of in vivo analysis, it was possible to demonstrate the ability of radiation at λ of 685 and 830 nm on increasing DHL enzymes and CS during the muscle regeneration process. Therefore, according to the outcomes it is allowed to attribute to the LILT an ability λ and dose-dependent of influencing the proliferation function and the metabolism of the MPCs. It was not possible to infer its effect on the cellular differentiation process, because of the inverted effect on the MHC isoforms expression, though.
