The of teaching profession is permeated by adverse work conditions, low wages, inadequacy of material and didactic resources, numerous classrooms, tension in the relationship with the students, excessive work load, lack of safety in the school atmosphere, inexpressive participation in the institution planning and in the institutional politics. The present study had for objective to compare work conditions and health, considering physical aspects with three groups of teachers who teach in elementary grades, as well as to investigate possible implications in the service to be provided to the students. Participated in the study 60 teachers of the Metropolitan Net of Elementary Teaching (1st to 4th grades) from the District of Bauru, distributed in three groups: a) 20 teachers who teach in regular school classroom without the inclusion of students with special educational needs RSI Group; b) 20 teachers who teach in the regular classroom with special needs students RCI Group; c) 20 teachers who teach in resource classrooms (SR Group). For data collection two instruments were used: Semi structured interview to investigate teachers perceptions about occupational health risks, as well as the Maslach Burnout Inventory MBI protocol to evaluate the burnout presence. The results were organized in form of tables and the data was analyzed by SPSS version 13.0 and by a non parametric Kruskal-Wallis test for comparison of the 3 groups. In general, the results demonstrated that the groups presented relative similarity. The teachers from the SR Group obtained the best results in the evaluation of the burnout three scales when compared with RSI Group and RCI Group, that is, with prevalence of answers in the lower levels of emotional exhaustion, high level of low personal accomplishment and low level for depersonalization. Related to the physical complaints, it was observed that RCI Group presented larger frequency of discomfort highlighting the head, spinal cord, neck and superior members. About the evaluation of the work conditions, the three groups considered the evaluated aspects (work environment, work organization, materials and equipments and pedagogic resources) as appropriate. However, RCI Group indicated larger indicators of inadequacy. Agreement was observed in the results of the two used instruments, in the sense that both of them indicate that RCI Group would be more vulnerable to develop emotional exhaustion referred to the physical aspects and work conditions, expressed by means of discomfort. In reference to emotional aspects, one of the components of the emotional exhaustion, RCI group presented larger percentile in seven of the fourteen investigated aspects. SR group presented the smallest percentile of incidence of the stress. Most of the teachers didn't present depersonalization problems. In relation to the decrease of the personal accomplishment, the three groups presented high scores, what characterizes low level since it is a negative scale. It is hoped that these results contribute for a better understanding of the burnout in teachers from regular classrooms with or without students with educational special needs and/or to raise new directions for investigation.

This dissertation deals with the "mega-rebellion" of 2006 that occurred at the prison units of the State of São Paulo. Seen, felt and observed from inside a penitentiary facilities, I tried to analyze it as a symmetrical and complementary ritual of solidary, enduring, suffering, and memorable bodies who, from time to time, are fed back by police officers, in the form of blitzes and punishments as a feedback to oppress, coerce and impart pain and suffering capable of causing effects such as domestication and docilization of the bodies. The fabrication of these mobile and gentle bodies that transit at the various State prisons, after being transferred to other locations as a result of outcome of the rebellion, has granted the Primeiro Comando da Capital (PCC) [First Command of the Capital] more territorial expansion, strenghtened by its ideology and transformation of unequal bodies into equal bodies. This ethnography approaches on how the prisioners fought for the PCC, by feeding themselves, retroactively, of their own production when they consumed their subtances, their fluids and their matters during the fighting process and punishing. At last, the prison rebellion turned out to be a symmetrical - complementary ritual that marked the whole continuum of procedures and behavior of thinking and resistant bodies under the "ideals" of the PCC. Strenghtened by the eternal love of their partners and confident in the divine justice, the prisoners overcame the suffering and continued their walk to freedom.

The synthesis of transition metal compounds mainly with ruthenium, has been increasing along the time, since compounds of this kind have many applications in the biological fields, among them, as anticancer agent. In this work were synthesized and characterized ruthenium compounds with amino acids of the general formula [Ru(AA)(dppb)(bipy)]PF6, AA = amino acid, dppb = 1,4-bis(diphenylphosphino)butane and bipy = 2, 2`-bipyridine, using as precursor the cis-[RuCl2(dppb)(bipy)]. Standard techniques were used for characterization of the complexes, among them: 31P{1H} NMR and 13C, IR, UVVis, Cyclic Voltammetry, Differential Pulse Voltammetry and X-Ray diffraction. Also, were made cytotoxicity experiments in cells of the type MDA-MB-231 to evaluate the citotoxity of the complexes. In the 31P{1H} NMR spectra of the complexes four doublets were detected with values close to 46, 44, 39 e 38 ppm with exception of the compound [Ru(Gly)(dppb)(bipy)]PF6 that presented only two doublets on 45,3 and 38,5 ppm. This suggests that there is a mixture of diastereoisomers for all compounds, with exception for the complex [Ru(Gly)(dppb)(bipy)]PF6. At the cyclic voltammetry of all compounds, except of compound [Ru(L-Met)(dppb)(bipy)]PF6 (irreversible) is observed a quasi-reversible Ru(III)/Ru(II) redox process with values close to 1100 mV. Also, there is another process of lower intensity above 1200 mV that is better observed by this differential pulse voltammetry that are attributed to redox process of the amino acids. The electronic spectra of the compounds are practically the same, showing bands around 290, 420 and 500 nm (shoulder) that are attributed to intra-ligand π→π* or to dπ(Ru)→π*(bipy) transitions. The diastereoisomers of the compound [Ru(L-Ser)(dppb)(bipy)]PF6 were separated by HPLC. These diastereoisomers were identified by circular dichroism spectroscopy (CD). Crystals of the compounds [Ru(Gly)(dppb)(bipy)]PF6 and [Ru(L-Leu)(dppb)(bipy)]PF6, were obtained and both showed the nitrogen of the amino acid to be trans to the phosphorus atom of the dppb and the oxygen opposite to the nitrogen of the bipyridine. The IC50 of all compounds in the cellular experiments with tumoral lineage were found to be lower than that one of the cisplatin, especially the IC50 of the compound [Ru(L-Met)(dppb)(bipy)]PF6 (5 μM), which is 17,5 time lower than the IC50 of the cisplatin in the same experimental condition.

The objective of this study was to evaluate the environmental sustainability of experimental agroforestry systems planted which aim was to restore degraded areas in a rain forest, in the municipality of Paraty, RJ. The model adopted is called as agroforestry system regenerative and analog (SAFRA), which combines leguminous and non-leguminous species in "single" (one plant /hill) and "married" (two plants/hill) planting. Thus, conical traps were installed to collect litterfall in the SAFRA systems and in a secondary forest in order to compare biomass and the intake of nutrients over a year. Individual trees were measured (circumference at breast height - CAP, commercial height - Hc; total height - Ht) and herbivory and mortality were evaluated. The forest productivity, litterfall and nutrients analyses demonstrated to be effective as environmental indicators applied to agroforestry systems. The "married" SAFRA model, independent of using leguminous or non-leguminous species presented silvicultural potential to be indicated as an agroforestry system. However, after five years, none of the SAFRA models may be considered as effective in the ecological function of restoration of riparian areas based on litterfall and nutrient when compared with secondary forest.

System reuse is a Software Engineering technique that proposes the construction of software systems from existing artifacts. One way to develop systems reusing code and project in a specific domain is using application generators. These generators automate part of the development process, reduce costs, allow the increase of the development team productivity, enhance systems quality and minimize error insertion arising from the implementation phase. The GawCRe (Web based Application Generator to the Rehabilitation Clinic domain) was developed using the software product lines technique based in the SiGCli (Rehabilitation Clinics Management System) pattern language. This generator went through some maintenance in order to allow the MySQL RDBMS usage, as well as to carry out version control of the generated applications and increase its domain to others related to it. Currently, there is interest in the usage of Service Oriented Architectures (SOA) to support the construction of software applications that use services available in a network, as the Web. These services are an implementation of well-defined business functionality that can be used by clients of different applications. The reutilization of available services in the construction of new Web systems is increasing, reducing the rework and facilitating the maintenance of these systems. This master's thesis presents an approach to modify application generators in a way that its domain is increased by the use of Web Services provided by Service Oriented Architecture. This architecture eases systems' adaptation, making them dynamic, as their services can be swapped in runtime. This allows future maintenances to be eased, because modifications in the services are reflected in the applications without user intervention. The GAwCRe undergone for maintenance to support the use of Web Services provided by a SOA, thereby, broadening its domain. A case study was conducted using the GAwCRe and some Web Services attempt to evaluate the combined use of SOA and Application Generators.

The transposition of the Piumhi River caused the introduction of many aquatic species in the São Francisco basin. Species previously restricted to the Upper Paraná basin, such as Leporinus octofasciatus and Parodon nasus, are now present in the São Francisco basin. However, the morphological identification of the invaders is not always possible. This becomes evident in the cases where the invading species are cryptic of native species, and when the newly introduced species already has a resident population. Therefore, the present work had the objective of characterizing and mapping the dispersion of a few invader species in the São Francisco basin using cytogenetic markers. Populations of Astyanax altiparanae, A. fasciatus and A. lacustris were analyzed. Besides a large chromosomal similarity, chromosome polymorphism where the two species were in sympatry was evidenced between the cryptic species A. altiparanae and A. lacustris, suggesting the occurrence of hybridization. On the other hand, differentiations regarding quantity and distribution of C-bands, AS-51 satellite DNA sites, Ag-NOR sites, and 18S and 5S rDNA sites, were seen between the A. fasciatus populations from the Upper Paraná and São Francisco basins. These chromosomal markers differentiated species from the Upper Paraná basin that invaded the São Francisco basin. No specimens with intermediary chromosomal characteristics between the native and introduced populations were found. This fact suggests that the Upper Paraná populations may constitute a distinct species.

The search for materials that posses exceptional hardness, resistance to high temperatures and chemical stability had expanded the areas of application and use of ceramic materials. The development of research about composites containing nanometric inclusions in its matrix increased due to the results of significant improvement in the mechanical properties of composites formed by an alumina matrix with nanometric inclusions of SiC. The mechanisms that enable the improvement of this property have not been fully justified. It was found that the presence of nanometric inclusions delay the beginning of the densification and shrinkage of the samples by raising the temperatura of sintering. This fact was the main motivation for the accomplishment of this work, that had as objective to study the sintering kinetics in the initial stage of alumina samples with and without the presence of nanometric inclusions of zirconia. The study method used was that proposed by Woolfrey and Bannister based on the work of Young and Cutler. With the application of this model, possible mechanisms acting in the system were identified. The samples had been gotten by the desaglomeration of the powders and posterior mixture in mill, isostatic pressing and sintering in dilatometer under constant taxes of heating of 3, 5, 9 and 15 C/min in air, with maximum sintering temperatures of 900, 1000, 1100, 1200, 1300, 1400 and 1500 C. The samples had been characterized how much its apparent density, specific superficial area and microstructure. A change in the mechanism acting in the initial stage of sintering was identified for samples containing nanometric inclusions of zirconia.

Greater stability of an agroecosystem can be achieved through the consortium system under organic management, becomes an important environmental factor to a highest stability of the agroecosystem. The objective was to study a system of production for organic crops of maize (Zea mays L., cv. BR 106), bean (Phaseolus vulgaris L., cultivar IAC Pérola) and manioc (Manihot esculenta CRANTZ, cv. IAC 15), intercropped with ratoon-cane (Saccharum spp.). The experimental design was a randomized, with eight (8) treatments and four (4) replicates, as follows: T1 ratoon-cane without intercropping (control), T2: ratooncane and intercropping of maize (cs + mi), T3: ratoon-cane and intercropping of bean (cs + fe); T4: ratoon-cane and intercropping of manioc (cs + ma), T5: ratooncane and intercrops of maize and bean (cs + mi + fe) T6: ratoon-cane and intercrops of maize and manioc (cs + mi + ma); T7 ratoon-cane and intercrops of bean and manioc (cs + f + ma), T8: ratoon-cane and intercrops of maize, bean and manioc (cs + mi + fe + ma). Productivity of the crops, the gross income obtained and the residual biomass waste of maize, beans and manioc, in each system were evaluated. For the conditions of the experiment, the treatment intercropping maize (T2) showed the best results on productivity of green maize ears (kg/ha), production of biomass (kg/ha) and gross income (R$/ha). The alternative of the consortium of distinct crops with ratoon-cane proves to be an effective technique that, from the viewpoint of agroecology, becomes an important tool for preserving and maintaining the agroecosystem, besides providing alternative foods and additional income to the farmer.

This work aim at developing models using linear programming, goal programming and robust optimization to support decision making in the frozen concentrated orange juice planning process. The proposed model includes orange harvesting plan, which takes into account oranges maturation curves. This fact leads to a model that incorporates a large portion of the supply chain involved in the frozen concentrated orange juice sector. Another point to highlight is the inclusion of the blending process of different types of juices to match ratio specification of the product. This study uses orange acidity to calculate ratio specification of the product. This study also explores the importance of data uncertainty incorporation to the aggregate production planning for this business and evaluate results from different approaches of robust optimization to this problem. This author is not aware of previous work in the literature with such approach to the orange juice industry. The problem modeling uses blending problem concepts and production planning with multiple products, stages and periods concepts as well. To solve the linear programming, goal programming and robust optimization models, an algebraic modeling language and a state of art optimization solver of mathematical programming problems is used. A case study was developed in an orange juice company located in the São Paulo State. This company has many facilities and a worldwide distribution system, similar to other companies in this sector. The results show that the proposed approach can be used in real situations.

The research focuses on the construction of knowledge about teaching practices in environmental education, linked to the social perspective, transformative, democratic and dialogical. We have the participation of two teachers of the Collective Environmental Educator of Campinas (Coeduc), part of the National Training of Environmental Educators (Profea) guided by the guidelines of the national environmental education. We traveled paths with teachers identifying the obstacles in their practices and ways of overcoming these, towards the school we want. We conducted our research with the guidance of the communicative and qualitative methodology. We approach the critical method of communication, who guided us on the instruments for data collection and analysis procedures, ensuring the intersubjective dialogue and reflection, enabling deep learning, processing and discussion about the capabilities of interpretation of reality made by the subjects who live . It will explain that the school needs to ensure access for people demanding activities and practices in context and reflective about the environmental problems of today. Thinking of overcoming inequalities, strengthened and generated by the mainstream in the information society, we choose the critical environmental education and dialogic learning, elucidated by authors who bet on the contribution of education for social transformation. Therefore, we raised a record on the information society and the environmental movement, environmental education and its context. We point out the theoretical underpinnings of the dialogic learning, explaining the communicative action Habermas, Freire and dialogical in learning and development in Vygotsky to support our research. Before the analysis with the teachers realize that the power of collective participation and the possible changes in the school environment and beyond. An instrument is a communicative action, with proposals to transform reality, linked to contexts, cultures and personal experiences, especially the intersubjective interactions. In this sense, the critical environmental education built as public policy is marked by great challenges also faced by social movements, education, involving different people and institutions who strive for a school and a society more just, equitable and environmentally sustainable.

The study evaluated two versions of a computerized program for teaching reading skills (de Souza e de Rose, 2006) which was intended to teach the relations between sets of stimuli consisting of a written word, a picture and a spoken word. Although developed to ensure that the apprentice advance at his own pace, the steps of this program were designed to teach fixed sets of three words. This meant that until he reaches the criterion of 100% of hits for the whole set, the participant keeps repeating the same step. This feature may require a number of unnecessary steps, and also result in damage to the motivation, as the participant can judge he is not progressing. The objective of this study was to determine whether a new organization of the steps of teaching, including only words whose relations are not mastered by the participant, could expedite the conclusion of the program. Additionally, it embedded a virtual album of stickers with the function of providing feedback to the learner of his performance. The stickers were presented as a consequence to the establishment of relations between the stimuli of each of the sets. In Study I the new procedure was introduced to five participants who were being exposed to the original persion and the results showed an acceleration in the pace of learning for four of the five participants. In Study II, the assessment of reading is held throughout the cumulative baseline and not only for last 15 words of the unit, as determined in previous procedures. The program was completed when the participant completed the reading of 60 words. Eleven students with different entry repertoires in reading completed the Study II. The data were compared to 14 students with similar repertoire that had completed the original version. The new version resulted in a decrease in the total number of sessions for most participants. A more pronounced decrease was observed in achieving the first half of the expected repertoire in this study. Another result observed was greater number of words taught by the intermediary sessions. The new contingencies of teaching led to a higher individual progress, greater variability in the content taught and can accelerate the progress of the participant.

The dynamics of use of land in urban and agricultural areas has led to destruction and fragmentation of ecosystems. It has been related to the increase of susceptibility of natural populations to extinction due to increase of isolation between populations and reduction of population size. To evaluate the effect of the recent habitat fragmentation on the genetic diversity of natural populations, we will analyze the diversity and genetic structure of populations of the wooly mouse opossum Micoureus paraguayanus (Marsupialia: Didelphimorphia) in the Parque Estadual Morro do Diabo (SP) and in bush fragments in its surroundings. For this purpose, we used the control region (D-Loop) to examine population structure and dynamics in fragmented forest habitats. We found low values of haplotypic and nucleotidic diversity when compared to values from previous works with marsupials in fragmented areas. We found values of diversity of 0.28 and 0.0022% respectively. Besides that, there was a correlation between continuous cultivated lands distance and number of exclusives haplotypes. The AMOVA test showed no genetic structure between fragments, however, Fst values indicated significant genetic differentiation to Santa Tereza and Ponte Branca when compared with all the others fragments. These are between the smallest areas evaluated in this study and the differentiation indicates that the recent fragmentation suffered by these patches could be responsible for the changes in the genetic composition of these populations.

In this work we used the technique of scattering matrix to calculate the transmissivity of polarized spins in a semiconductor symmetrical double-barrier heterostruture. The dynamics of carriers is described by effective mass approximation applied to models of Dresselhaus and Bychkov-Rashba. In the former case, the hamiltonian was studied in its full form, free of approximations. Both models describe interactions of type Spin-orbit, which is basically a coupling between the orbital angular moment of the electron with its magnetic moment of spin. This type of coupling as a consequence creates a splitting of some levels of energy, initially degenerate, resulting in a spectrum of energy more complex than that obtained without taking it into account such interactions. The transmissivity is calculated as a function of some parameters, for the type InAs=GaSb=InAs=GaSb=InAs. All results are compared with literature, and provide new information about the systems. The effects of spin-orbit interactions of Rashba and Dresselhaus show is very favorable to engineering in the manufacture of .lter spin and spintronic devices, as well as the injection of spin in quantum wells and semiconductor detectors based on non-magnetic asymmetric double barrier.

The purpose of this work is to evaluate, according to the population s perception, the benefit to the environment by treating the sanitary sewers flowing into the Limoeiro stream located in Presidente Prudente, in the state of Sao Paulo. It is sometimes difficult to place a value on natural resources and this research attempts to develop a method to place a value to this particular natural resources, the Limoeiro stream. By making it possible to have a base of common comparison, the financial value, provides a justification for investments in environment conservation projects. With this objective, the contingent valuation method was used to evaluate the natural resource which investigated the disposition of the population to pay for this process in two types of scenarios. In the first scenario, which presents the legal view of the conservation, determined that it would be R$ 5,12 with 95% of entrust and a plus or minus 10% margin of error. In the second scenario, which presents the ideal view of the water course conservation would be R$ 7,35 also showing a 95% entrust and a plus or minus 10% margin of error. A period of 30 years was stipulated and the global liquid present value between R$ 9.126.914,16 to R$ 16.011.288,26 with a discount tax of 12% of the capital.

Noninvasive positive pressure ventilation (NIPPV) has been commonly applied in several clinical and postoperative conditions, especially after coronary artery bypass grafting (CABG) surgery and it can cause breathing pattern (BP) alterations and mechanical effects on cardiovascular system, with cardiac autonomic adjustments. However, it is not well established in the literature how these alterations occur in patients submitted to the CABG and if they can be related to the application of different positive airway pressure levels. In this context, we considered the development of two studies that could contribute with new information about these topics. The first study is entitled Acute application of bilevel positive airway pressure influence cardiac autonomic nervous system and its objective was to evaluate the changes in heart rate variability (HRV) during bilevel positive airway pressure (Bilevel) application in healthy young men. Twenty men underwent a 10-min register of R-R intervals (R-Ri) during sham ventilation, Bilevel 8-15cmH2O and Bilevel 13-20 cmH2O. HRV was analyzed in time and frequency-domain and with non-linear statistical measures. Physiological variables (blood pressure, breathing rate, end tidal carbon dioxide- ETCO2) were also collected. R-Ri mean, rMSSD, NN50, pNN50 and SD1 reduced during 13-20 cmH2O compared to sham ventilation, with reduction of the R-Ri mean compared to 8-15 cmH2O. R-Ri mean and high frequency band (HF) reduced and low frequency band (LF) increased during 8-15 cmH2O compared to sham ventilation. Delta of ETCO2 correlated positively with LF, HF, LF/HF, SDNN, rMSSD and SD1. In conclusion, acute application of Bilevel was able to alter cardiac autonomic nervous system, with parasympathetic activity reduction and sympathetic increase and higher level of positive airway pressure can cause a greater influence on the cardiovascular and respiratory system. The second study is entitled The effects of different levels of positive airway pressure on respiratory pattern and heart rate variability in patients submitted to coronary artery bypass grafting surgery and its objective was to access the effects of different levels of continuous positive airway pressure (CPAP) in BP and HRV in CABG postoperative (PO), as well as the impact of CABG in these variables. Eighteen patients underwent CABG was evaluated during spontaneous breathing (SB) and four different CPAP levels of CPAP, in a random order: (a) CPAP = sham (3 cmH2O), (b) 5 CPAP = cmH2O, (c) 8 CPAP= cmH2O, (d) 12 CPAP = cmH2O in PO. HRV was analysed in time and frequency domain and by non-linear methods (Poincaré plot e Detrended Fluctuation Analysis) and BP was analysed by inductive respiratory plethysmograph. There were significant alterations of HRV and BP in the PO of CRM, compared to pre-operative and alterations of DFAα1, DFAα2 e SD2 and respiratory variables during NIPPV, with higher influence observed during application of the two higher levels applied. Moreover, there was relationship between DFAα1 and inspiratory time of delta 12 cmH2O and SB, and 8 cmH2O and SB. In conclusion, acute CPAP application was able to alter the control of cardiac autonomic nervous system and BP of patients submitted to CABG and higher levels promoted better performance of pulmonary and cardiac autonomic function.

This is a search on the Catholic religious order and the legal system represented by the criminal law, showing how, according to its regulatory structures, subject to mechanicalrelated offense and the punishment. It is shown how, through a language that uses symbols of both the Church and the State seek to make individuals internalize the values and standards of conduct, to lead them to a range of desirable behavior. The internalization of the feeling of guilt and will be punished eventually integrating this universe of values and modeling behaviors. Thus, a control system based on the prospect of punishment, and before that, in the formation of consciences, has an important social role and falls in a real educational process. This is an education geared towards the stabilization of patterns institutionalized, in tune with the current model of economic development. The symbolic interactionism highlights the intense use of symbolism in the formation and communication of these standards. The perspective of historical materialism shows that the stage of organization of productive forces is a fundamental element that ideology and thus determines the evolution of mechanisms of sedimentation and its control. The criminal law as well as other rights, here treated as the legal system in force, plays the dominant ideology and draws upon models of transgressions and sanctions, the limits of human conduct and, consequently, the way forward. The Catholic religious order also taken as a normative structure called the Roman Church, seeks to establish a line of procedure which lead to the salvation of the individual. She goes down a path whose bases can often be explained historically, but the search for redemption in a virtual world means that its postulates are situated in a plane that transcends life itself. The acceptance of religious dogmas usually occurs before the law. The rich symbolism employed in its communication to humans contributes to the insertion depth of their culture and values in developing a sense of guilt before the fear of punishment by the state power, before it has also collaborated with him. Church and state, thus moving together in the formation of desirable standards of conduct. With a broadening of horizons of the religious order and the legal as well as formal education, it seems, however, possible to mark positions in a counterhegemonic history, which tends to expand the boundaries of the emancipation of the individual.

Today, Brazil is the major producer and exporter of sugar in the world. In the last harvest 2008/2009, 31.5 millions tons were produced, of which 60% were exported providing a 40% of international market share. However, sugar is a product that has commercial difficulties, due to the hard restrictions, such as rates, subsidizes and technical barriers like the use of sulfur (input) in laundering. Because of this, the development of a technology for the production of sugar with superior quality, less cost and without sulfur for the laundering would be of great interest for the productive sector. The present work aims to study the process of crystallization of sucrose from sugar solutions of syrup and sugar cane by controlled cooling. A laboratory plant with production capacity of 1 kg of sugar per batch, installed in the laboratory of industrial development of the Sugarcane Technology Center (CTC) in Piracicaba was used for the present work. The results regarding the reduction of impurities initially present in sugar crystals through crystallization by controlled cooling were: 95% in color, 85% in starch and 80% in dextran. For the syrup classified as VVHP, reductions obtained in crystals through crystallization by controlled cooling were: 96% of the final color of the sugar (from 10,100 IU to 361 IU), 98% in the amount of ash conductivity, 84% in the amount of starch and 52% in the amount of dextran. Obtained the results led to the construction of a pilot plant by scaling the process that will be implemented in an industrial unit.

Technological based firms (TBFs) have been widely studied because of its importance in the nation´s innovation system. Health industry is one of the most innovative sector at the economy and it´s constituted also of great corporations and health care manufacture equipment and biotechnology small firms that compete at health equipment manufactory and biotechnology market niches. Ribeirão Preto is characterized as one of the technological region at São Paulo state. The development of SUPERA is one of the strategies adopted to consolidate the city as a health technological polar region. This work analysis the social relations between technological-based firms and institutional agents of health sector. For this purpose it´s used social networks methods to calculate specific measures such as density and centrality degree of actors. It evidences that SUPERA is at the center of studied information and cooperation networks. Theorists defend that these kind of network support companies´ innovation process and its competitiveness. The analysis of density and centrality measures so as actor´s scores of 2-mode matrices where calculated using the software Ucinet. The results confirm the central role of SUPERA for the creation of new TBFs; identify that the studied firms are inserted in low density networks and that strong relations seems to exist more frequently in cooperation relations between university-firms rather than with another institutions. It concludes that there are few entrepreneur´s information exchange relations and that they do not recognize the relevance of institutional agents in the firms innovation process. Cooperative action is almost inexistent or occurs in the informal level without relevance to the TBFs´ innovative system. The incubation process seems to be the extension of academic projects that tends to the mantain the distances between firms and market reality.
