With the progress of the sequencing techniques and the inevitable increasing number of sequenced genomes, it becomes interesting studying computational techniques to analyze these data. One of the possible analyses refers to the extraction of functional and evolutionary characteristics of the studied organisms. Thus, in this line of research, this study is motivated in identifying common regions, in terms of the genes that they contain, in multiple proteomes that keep the order and the gene content. The problem is modeled with a colored graph, and the common regions between proteomes are like clicks in the graph. Using peculiarities of the constructed graph, an algorithm for search space reduction was developed, making it possible to get complete results in a short time. Therefore, the contribution of this work constitutes an approach to find common regions in multiple proteomes, added of an implementation from which the Multiple Proteome Comparison (MPC) tool originated.

This work presents a computer aided system for automated counting of colony formation units in Petri dishes. The method implemented uses digital image processing, and among them Hough transform for circular objects and Match for correlation with objects having different forms. The method was developed based on the visual Borland Builderr C++ environment, and for the image acquisition a luminance equalization system was used to allow stabilized and continuous 1,200 lux. For the validation of the method, samples containing Acidithiobacillus ferrooxidans, Escherichia Coli, and Staphylococcus aureus were analyzed. Results have shown the potentiality of the methodology, which is applied for laboratory applications that involved the quantification of bacterial colonies in a solid culture environment.

During the last quarter of the nineteenth century, Brazilian psychiatry has based its speeches on sexuality. It became the main element in the classification/institution of deviant identities after 1870, in the period of the Empire decline. The appearance of the so called new ideas and the anti-slavery measures created fears of the black population understood as a social danger that lead to a new way of comprehension of Brazilian society and its deviant identities. These theories about social deviance have used sexuality as one of the strategies that made possible the critique of the old imperial order and the consolidation of the bourgeois one as well. The objective was to avoid social change keeping social inequalities and hierarchies from the past.

The importance of ultrasound limited-diffraction Bessel beams in medical images, tissue characterization, and estimation of Doppler speed (blood flow) as well as in many other areas of Physics has increased in the two last decades. In this work an alternative solution to produce a transducer of limiteddiffraction was implemented, with the polarization following the geometry of the Bessel's function. These transducers (also called Bessel Transducers) have been constructed using a ferroelectric ceramic PZT doped with Niobium, by means of a simple technique of polarization. The electrodes in the faces of ceramics were made with a silver painting in form of three concentric rings. Through experimental simulations and measurements, the vibration's modes as well as the acoustic field of radiation has been characterized. For the simulation, the method of finite elements was applied. For these transducers it was verified a decoupling between the modes of radial and thickness vibration. The fields radiated have shown that there are less effects of diffraction on Bessel transducers than on the conventional transducers. With this new implemented technology, not reported before in the literature, the limited-diffraction transducer does not require a sophisticated electronic set up to excite acoustic waves in the transducer, allowing to get a collimated radiation field desirable for medical applications with optimized lateral resolution.

This dissertation presents an environment for the development of reconfigurable applications, with Virtuoso Real-Time Kernel, called RTEV. This work is based on the TEV (Teaching Environment for Virtuoso), developed at DC/UFSCar (Department of Computation of the Federal University of Sao Carlos). In RTEV, it is possible to carry through the development of applications only selecting a reconfigurable function from the library of available functions and making the interconnections with other functions of the applications. It will be presented, for better understanding: a reconfigurable computer review; development methods of functions and/or applications that can be used for the construction of the reconfigurable library; the systems used in the development environment RTEV; and a case study as a way of validation of the development environment. This environment allows the programmers, without any reconfigurable hardware knowledge, to develop applications with reconfigurable components.

The last decade was scenery of big transformations, among them the social revolution caused by Internet stand out, changing the way that people find information, communicate and buy products and services. Moreover, the convergence of telephony, informatics and consume electronic, supplies more and more mobile devices equipped with Internet access through wireless network. This changing caused a big problem to the Internet content available at Web: how the same content should be adjusted to different kinds of users witch have particular preferences, and be presented in mobile devices featured with a big diversity of functionalities? To solve this problem, many research proposals are been developed at content adaptation area. One challenge of this area is define, from a user request, witch adaptation services are necessary and these execute sequence. In order to have the best decision, delivery context and the available services have to be acknowledged. This information are described at profiles and rules, considering that nowadays the majority of proposed solutions are based in proprietary models and not compatibles among each other. As well, the discovery of services generally is strongly based on syntactic matching, what weak the discovery and composition of services. Intending to contribute with content adaptation area, this dissertation defines an ontology-based set of profiles and reused. Furthermore, shows how the rules have to be integrated with services profiles, providing a rules and profiles independent solution. Also are presented the benefits use of semantics at match and composition of services in an open environment such as the Web. The implementation and the case study of this proposition were based at a component-based content adaptation framework. With the purpose of extend its functionality, in order to support ontology, and others necessary functions, components were reused, adapted or created. This extensions made possible achieve the case study and the validation of proposed solution.

The professional education for people with special educational needs intends to promote the development of the potentialities of these individuals, with the objective of supporting the complete exercise of the citizenship. It s necessary that the responsible institutions for the preparation for the work accept people with special educational needs. This opening can provide the implantation of real steps that minimize the social exclusion and facilitate the access for people with special educational needs to the work world. In a country with so many social inequalities, the inclusion of people with special educational needs in education programs for the work presume the enlargement of the presence spaces of these people in high and professionalizing schools, also in Technological Education Federal Institutions. In this sense, the study takes place in the setting of the special education public politics into the field of the professional education for people with special educational needs, with the focus in the Program TEC NEP (Education, Technology and Professionalization for People with Special Educational Needs) as a proposal of expansion of education and professionalization in the federal net institutions settings. The TEC NEP Program is a proposal for professional education implemented by the Special Education Secretary connected with the High and Technological Education Secretary intending to expand the offer of professional education, access and permanence in the work for people (young and adults) with special educational needs. The aim of this study was estimating how the guidelines proposed in the TEC NEP Program are being implemented in the federal net schools, through the perception of the nuclei coordinators. Twenty nine nuclei coordinators took part of this study. The data were obtained through the questionnaires sent by internet to the 32 schools which had, until 2005, instituted formal nuclei of the program. 29 coordinators nuclei filled and gave back the questionnaires. The data were analyzed quantitatively and qualitatively and synthesized to offer information about characteristics of the informers and institutions, description of the implementation of the TEC NEP Program in the federal net schools, selective process characteristics, registrations number of students with special educational needs, partnership support, strategies to aid the school inclusion for students with special needs, insertion in the work market, program financing, difficulties in implementing and managing, program impacts and suggestions and considerations brought by the informers. The results obtained after six years of implantation of the program show that its reach is still restrict, considering that in 20 of the 29 schools, the nuclei were implanted only within the two last years and only about fifth of the schools (32 amongst 144) had nuclei of the program. In 19 amongst 29 investigated schools, the nuclei coordinators reported that their schools had already former report of registration of students with special educational needs even before the implantation of the nuclei. The number of investigated schools with registration of students with deficiency raised for 21 in 2005. In the 29 schools investigated were notified 379 registrations of students with special educational needs. However, it s useful to stand out that 244 students with deficiencies (65%) were in courses of initial and continued formation which didn t demand scholastic level. Moreover, only 4 amongst 29 schools concentrated about 71% of the 379 registrations of students with deficiencies, showing the small reach of the program. 8 Therefore, it s observed that the number of registrations of students with special educational needs in the federal net schools is still little significant, what can be connected with the difficulties for the access and permanence conditions of this population in these institutions, since they only can entry through selective examination. The considerations of the coordinators appoint the necessity of taking measures to modify the structures of the schools, implant support services, review curriculum questions, re-define the evaluation process, provide teaching staff formation; it s necessary the involvement of the whole school community in the pedagogical project of the school. Through the reports of each institution, it s still perceived the priority necessity of eliminating prejudiced attitudes, adjust programs, offer pedagogic support, elaborate budgets for the nuclei and qualify continuously all the professionals that work in it. It was verified that the quantitative of students with deficiencies in these schools, even not so significant, is due to partnerships with ONG s (Not Governmental Organizations), what means the transfer of the government responsibility. Concerning to the leading to the work market, it s verified that some few institutions did the control of this datum and the lack of this information hinders a proper evaluation about the effectiveness of the program. It follows that the adoption of isolated measures for the creation of opportunities for access in the federal institutions will make not sense if it s not connected with the taking of steps in the Reabilitation, Education, Health and Transport areas, in order to allow the access and the permanence of these people to these institutions. Thus, it seems necessary a larger planning, accompaniment and evaluation about the measures proposed by the Program for the responsible organizations.

The hypothesis of a synergy between two hormones responsible for sodium conservation, aldosterone and angiotensin II (ANG II), explains the expression of a characteristic of sodium appetite, hypertonic NaCl intake, in a hypovolemic animal. Hypertonic NaCl intake can be induced in normovolemic rats that received a combined treatment of mineralocorticoid and ANG II at individual doses not sufficient to induce sodium intake (paradigmatic synergy test). Considering the motivation to specific sodium intake another characteristic of sodium appetite, the objective of the present dissertation was to find out a role for the interaction between mineralocorticoid and ANG II on the specificity of sodium appetite. Sprague-Dawley Holtzman rats (≅ 300 g b.w.) were housed with access to water and one or more palatable (0.01 M KCl, 0.05 mM CaCl2, 0.15 M NaHCO3, 0.15 M NaCl) or hypertonic (0.50 M NaCl) mineral solutions for ingestion. In two-bottle tests, a bottle contained water and another bottle contained either 0.01 M KCl, 0.15 M NaHCO3, 0.15 M NaCl or 0.50 M NaCl. In five-bottle tests, a bottle contained water and each one of the remaining four bottles contained either 0.01 M KCl, 0.05 mM CaCl2, 0.15 M NaHCO3 or 0.15 M NaCl, respectively. In sodium depletion tests, intact rats received each a 10 mg sc. injection of furosemide or vehicle followed by 24 h access to sodium deficient food and water. Then, food was removed and mineral solutions and water were offered for recording their intake (sodium appetite test). In the paradigmatic synergy test, the animals received daily single sc injection of 2.5 mg of deoxycorticosterone acetate (DOCA) or sunflower oil (vehicle) for three days and a left lateral cerebroventricular injection of 50 ng of ANG II four hours after the last DOCA or oil injection. Fluid intake record began immediately after ANG II injection and food removal. The daily intake record showed no preference for any solution or water when animals had access to five bottles. Sodium depletion induced a preferential sodium intake, with higher NaCl than NaHCO3 intake, in either two- or five-bottle sodium appetite tests. DOCA alone enhanced the daily 0.15 M NaCl and NaHCO3 intake, but did not alter KCl or 0.50 M NaCl intake in two-bottle tests. In the paradigmatic tests with normovolemic animals, ANG II combined to oil induced the ingestion of all three palatable mineral solutions (KCl, NaHCO3, NaCl) and water, in two-bottle tests, and preference for NaHCO3 in five-bottle tests. DOCA pretreatment enhanced only sodium solution intake, particularly NaCl intake, induced by ANG II in two-bottle tests (0.15 M NaCl: DOCA/ANG II = 24.5 ± 6.7 ml/120 min. vs. OIL/ANG II = 9.2 ± 1.8 ml/120 min.; 0.15 M NaHCO3: DOCA/ANG II = 17.0 ± 1.8 ml/120 min. vs. OIL/ANG II = 14.6 ± 2.1 ml/120 min.; 0.01 M KCl: DOCA/ANG II = 9.8 ± 1.9 ml/120 min. vs. 11.9 ± 1.2 ml/120 min.), and enhanced by 80 % the total sodium solution intake in the beginning of the five-bottle test. The combined effect of DOCA with ANG II on the induction of 0.50 M NaCl intake in a two-bottle test was replicated in our animals. The results from the paradigmatic synergy test are coherent with results from sodium appetite tests, suggesting that the mineralocorticoid may turn the effect of ANG II on mineral intake more selective to sodium intake. Thus, the combined ANG II and mineralocorticoid action could contribute to the expression of two characteristics of sodium appetite, not only the acceptance of hypertonic sodium solutions, but also the selective sodium intake.

The main goal of the present work is to describe the lithium ion transport mechanism in a hybrid (SPHP) and nanocomposite (NHP) polyelectrolyte based on complex conductivity analysis as a function of temperature. The chemical synthesis strategy used to produce a helical free-chain configuration of singlephase hybrid organic-inorganic polymer electrolytes was based on a simple non-hydrolytic sol-gel route. The SPHP resulting from this strategy showed a Tg of -79oC and its temperature-dependent ionic conductivity (achieved at temperatures higher than Tg) displayed an Arrhenius behavior. This remarkable behavior characterizes a segmental motion-decoupled polymer. An Arrheniustype behavior for ionic conductivity (σdc) and hopping frequency of charge carrier (ωp) were observed. The values of activation energy obtained for σdc and ωp as a function of the temperature was approximately the same (~ 0.2 eV), indicating that the dispersive conductivity, σ(ω), originates from the migration of ions. This relevant physical aspect is allied to the fact that the contribution to the dispersive conductivity appears to be governed by a nearly frequency independent dielectric loss, ε = A, which correspond to an almost linear frequency dependent term of the form, σ = ωε ( ω) = Aω, in the real part of the complex conductivity. Furthermore, we observe a high stability, of SPHP and NHP when applied in a large EC device (5 x 10 cm2) using WO3 (electrochromic) and CeO2 -TiO2 (counter-electrode ion storage) electrodes, both optimized and produced by Leibniz-Institut of New Materials (Leibniz-INM, Germany). The electrochromic device exhibited excellent color and bleach reversibility, high coloration efficiency (> 35cm2 / C) from the first cycle up to more than 60000 CA cycles, and a maximum constant rate of deintercalation / intercalation (Oout / Qin = 1). Its remarkable behavior and high stability render this material an excellent candidate for application in electrochromic devices.

The present research work relates with the musical formation subject of teachers from basic education initial grades and had as objective to discuss and characterize the musical formation of three teachers licensed in pedagogy, emphasizing the initial stage role (graduation course) of this formative passage professional professor. This inquiry methodology was placed in the Qualitative Research scope, approaching the Bibliographical Research, prioritizing the data collection related to the teachers musical formation by halfstructuralized interviews and using the analytical descriptive method for the collected information exposition. The first chapter presents the bibliographical revision on the thematic of the teachers formation in present time, emphasizing the formative passage different stages. The second succinctly delineates the active teachers musical formation working at the initial basic education grades throughout the years, since the Brazilian Normal Schools creation until the current pedagogy courses and, by its end, shows some correlate researches already carried out in the teachers initial musical formation scope, studies that aims at demonstrating how such formations are configured nowadays. The third chapter explicates the methodological ways covered by this study, as well as the interviewed educators profiles. And the last one brings the exposition and discussion of the collected information, which were classified and organized from five analytical categories: Artistic-musical formation in the pre-training phase; Specific musical formation; Initial musical formation; Complementary pedagogicalmusical formation comedy; and Teaching initiation. The data interpretation glimpsed that the initial musical formation is only one of the formative course stages, which supplies the necessary theoretical and methodology bases so that teachers start teaching and search for a permanent and continuous musical formation.

In this thesis are presented the development of flow injection analysis procedures with spectrophotometric detection for determination of furosemide, paracetamol and acetylcysteine in samples of pharmaceutical formulations. A flow injection system was optimized for indirect determination of furosemide monitoring the excess of sodium hypochlorite not consumed in the reaction with the furosemide using o-tolidine as reagent at 430 nm. The analytical curve was linear from 5.0x10-6 to 8.0x10-5 mol L-1 and the detection limit was 2.5x10-6 mol L-1. A RSD smaller than 2.0% (n=10) for 1.0x10-5 and 5.0x10-5 mol L-1 furosemide solutions and an analytical frequency of 60 determinations h-1 were obtained. Another flow injection system was proposed to determine paracetamol in pharmaceutical samples employing sodium hypochlorite and o-tolidine as reagents. In this flow system, sodium hypochlorite reacted with paracetamol and its concentration in excess was monitored with o-tolidine. After system optimization, the analytical curve was linear in the paracetamol concentration range from 8.5x10-6 mol L-1 to 2.5x10-4 mol L-1 with a detection limit of 5.0x10-5 mol L-1. A RSD of 1.2% (n=10) was obtained for 1.5x10-4 mol L-1paracetamol solution. The analytical frequency of the system was 60 determinations h-1. The otolidine and its products used in both proposed flow injection systems were on line destroyed using an ultraviolet lamp (λ=380 nm) and hydrogen peroxide solution. The reversed flow system was proposed for determination of paracetamol employing sodium nitrite as reagent. The product formed was monitored at 400 nm. The analytical curve was linear in the paracetamol concentration range from 4.0x10-5 to 1.1x10-3 mol L-1 with a limit of detection of 2.0x10-5 mol L-1 and analytical frequency of 45 determinations h-1. RSD smaller than 2% were obtained for 8.0x10-4 and 1.0x10-3 paracetamol solutions. A flow system injection procedure with spectrophotometric detection to determine acetylcysteine was developed. In this procedure, acetylcysteine reacts with Ce(IV) solution and the excess of cerium (IV) was monitored with ferroin at 500 nm. An analytical curve ranged from 1.32x10-5 to 1.35x10-4 mol L-1 with a limit of detection of 8.0x10-6 mol L-1 were obtained. A RSD of 1.4% (n=10) for 2.2x10-5 mol L-1 acetylcysteine solution and an analytical frequency of 60 determinations h-1 were obtained. Another flow injection system for determine acetylcysteine using bromine (Br2) as reagent was also proposed. In this system, Br2 chemically generated on line reacts with the analyte and its excess monitored at 400 nm. The analytical curve obtained was linear from 1.6x10-4 and 1.6x10-3 mol L-1 and RSD of 1.2 % (n=10) for 5.3x10-4 solution were obtained. The system showed the analytical frequency of 60 determinations h-1 and ascorbic acid solution was used to destruct bromine on line.

Nowadays, some projects of genomes of different organisms are being analyzed generating a great volume of data, which are stored in heterogeneous and distributed data sources. Moreover, there are available tools in the genome domain that also need to be integrated. Another problem is that the systems developed for these objectives do not offer all the support to the researchers, therefore in their majority do not possess flexibility and are of difficult expansion. The proposal of this work is the development of a software component framework, called FrameEST, developed with the most recent technologies of reuses, that structures and guides the development of different applications of molecular biology domain. The FrameEST is available for reuses of the applications: in the phase of modeling in a CASE tool and the phase of implementation as one plug-in in the Eclipse enviroment. A case study is used to illustrate the FrameEST reuse.

Anabaena spiroides and Microcystis aeruginosa are cyanobacteria that frequently bloom in Barra Bonita Reservoir. These floating organisms and the characteristic turbulence found at the reservoir exposure the cells to higher light intensities by lifting them from lower depths in the photic column to surface. The sudden exposure at higher irradiance could cause photoinhibition and photooxidation. This phenomenon could liberate high amounts of dissolved organic matter. This work aimed to investigate the carbon fixation photoinhibition in cells of A. spiroides and M. aeruginosa exposed to high irradiances, the chlorophyll photooxidation and the DOM released by cells of cultures differing in their physiologic state, after exposure to high irradiances through time at laboratory and field investigations. A. spiroides suffered photoinhibition and liberation of dissolved organic matter when exposed to irradiances higher than their EK during four hours as well as when exposed to irradiance of 2000 µmol.m-2.s-1 for eight hours. M. aeruginosa did not present photoinhibition in any case, however, their C14OD liberation was significantly increased. The higher indexes of C14OD excreted by theses cyanobacteria are not apparently due to cell damage. Hence it might represent an adaptation factor to higher irradiances. Similar results were found in experiments incubated in Barra Bonita reservoir.

This work describes the similarities and differences in the work process of treating ornamental stones, comparing this against two periods of time (1890-1950 and the present time), the technological stages and work organization in marble and granite companies of the past and of the present. Data collection was based on various research sources and qualitative techniques (systematic direct observation and oral statements) and quantitative research (survey interviews). It was verified that the local marble and granite companies - since the end of the XIX century up until the present time - are installed in the mercantile establishments that operate in the third main stage of the productive cycle of the ornamental stones, elaborating final products from unrefined or polished slabs that are supplied by third parties. The semi-craft work organization and arduous work conditions seem to be conditioned to the technology employed by these companies. Along the XX century, local companies underwent technological improvements and upgrading, using new equipment and tools that increased efficiency of the final treating process. However, such technological changes did little to significantly improve work conditions and to eliminate predominant manual work with mechanical tools; although the work has been disassociated with partial craft work, the worker s skills remains the basis of the work process. However, the local companies have been incapable of modernizing their work units, not upgrading their systems with relation to available technologies worldwide. Mechanization and automation of the process, already incorporated by many companies in this sector, could modify the profile of the variables afore mentioned. Nevertheless, the small local companies are incapable of substituting or upgrading their equipments due to their low capitalization level at the rate the market develops and presents equipment.

With the aim of analyzing the dynamic and the taxonomic composition of the Chironomidae, samples were taken through a transversal transect in two different periods (dry and wet season), comprehending the phenological cycle of Mayaca fluviatilis Aublet, 1775. From a total of 27 Chironomidae taxa, it was verified that the most abundant taxa in the dry season were: Cladopelma, Caladomyia sp1, Caladomyia riotarumensis, Djalmabatista pulcher, Ablablesmyia (Karelia), Tanytarsus rhabdomantis e Labrundinia. On the other hand, in the wet season the most representative were: Polypedilum (Asheum), Chironomus, Goeldichironomus, Endotribelos, Tanytarsus rhabdomantis, Caladomyia friederi, Ablablesmyia (Karelia), Labrundinia e Cricotopus. The greater taxonomic richness and number of specimens were registered in the sampled sites where Mayaca fluviatilis was present, indicating that the presence of this macrophyte was very important for structuring the studied community.

This work has as general objective to analyze the profile assumed for university professors from the areas of social science belonging to the São Paulo State Universities (USP, UNICAMP and UNESP), as well their opinions and reactions a respect of the fast socialeconomic, politic and cultural transformations occurred in the country in the last decades, whose influences reflect incisively on the university institutions and on the positioning of themselves with relation to their proper intellectual condition. In a more specific way we searched during this research to answer the following question: "How the university professors conceive their functions and what type of intellectuals our public universities are forming?" It is a qualitative inquiry based in structuralized open interviews by the way of a script previously elaborated using the research problem. Besides the development of the interviews has became necessary a bibliographical study about intellectuals, culture, university, university professors and society, having as theoretical referential the classic treatment on the elected subjects above, in special, the analysis about the scientific field developed by French sociologist Pierre Bourdieu. The collected data could evidenced that the university professors see themselves as responsible for the critical and for the possible intervention in the society, the academic intellectuals are pointed as those that possess the function to commit themselves to certain practices and try to realize specific changes in the environment in which they are inserted, their work is to be intent to their proper position and how this affects their studies. When describing their functions and reflecting on the university objective in the contemporary society, these protagonists point with respect to the inefficiency of this new model of university, implanted after the University Reformation in 1968, which gives privileges to the scientific and technological development, in order to stimulate the economic growth of the country, for the formation of new generations of intellectuals that, impressionable with the reduction of the time of the intellectual work and the intense production of bureaucratic reports demanded by the State and by the agencies of research promotion, specializes each time more early, disabling a intellectual work, in the sense of critic, reflexive and politician.
