Brazil has a large and dense hydrographic network distributed in eight major basins, with a great diversity of fish species. Erythrinidae is a small family of Characiformes, represented by only three genera: Erythrinus, Hoplerythrinus and Hoplias. Hoplerythrinus has only three species: H. cinereus (Gill, 1858), H. gronovii (Valenciennes, 1847) and H. unitaeniatus (Agassiz, 1829) and only the latter is found in Brazil, besides also occur in Central America and in several other countries in South America. H. cinereus and H. gronovii have a more restricted distribution and occur only in Trinidad and Tobago and Guyana, respectively. Only H. unitaeniatus has cytogenetic studies, proving to be a diverse chromosomally species, indicating it is a complex of species. In order to progress in the knowledge of the genome of H. unitaeniatus, this study aimed to characterize by conventional Giemsa staining, C-banding, impregnation with silver nitrate and fluorescence in situ hybridization (FISH) with probes of DNAr 18S and 5S, telomeric sequence (TTAGGG)n, histones (H3 and H4), and microsatellite (CA)15, (GA)15, (CAC)10, (GAG)10 and (GATA)n, populations of H. unitaeniatus from five hydrographic basin in Brazil (Amazon, Araguaia, Paraguay, Upper Parana and São Francisco). The diploid numbers found were 2n=48 (Paraguay and Upper Parana), 2n=50 (São Francisco) and 2n=52 (Amazon, Araguaia and São Francisco), besides the occurrence of natural hybrids with 2n=51 chromosomes in the São Francisco basin. The C-banding showed heterochromatic blocks located in the interstitial and pericentromeric position in most chromosomes, but some chromosomes also showed heterochromatic blocks in the centromeric and terminal position in all populations. The impregnation with silver nitrate revealed simple AgNORs for populations of the Amazon and Araguaia and multiple AgNORs for the populations of Paraguay, Upper Parana and São Francisco. FISH with 18S and 5S DNAr probes revealed several chromosomes carrying these cistron, besides the occurrence of synteny in all populations. Probes with telomeric sequence (TTAGGG)n detected sites only in the terminal vii portion of all chromosomes. A dispersed pattern was verified to H3 and H4 histones in the chromosomes and only for H4 was observed strongest blocks in the interstitial position. The chromosomal distribution of the microsatellites (CA)15, (GA)15, (CAC)10, (GAG)10 in the genome of H. unitaeniatus shown to be preferentially located in the terminal position of the chromosomes with some interstitial regions marked. The microsatellite (GATA)n shown dispersed in the chromosomes without preferential accumulation in a specific region of the chromosome in all populations analyzed. The data obtained in this study reinforce the hypothesis that H. unitaeniatus it is not a single species, but the specie complex H unitaeniatus.

The incorporation of environmental education (EE) in school curricula has shown to be a major challenge for environmental educators and educators in general. In this context, the aim of this study was to investigate the possibilities and limitations of the EE discipline, conceived from a critical perspective, for the training of students of the Environmental Engineering distance education course offered by UFSCar. The research methodology consisted of analyzing, throughout the discipline, the students conceptions regarding the concepts of EE and sustainability, as well as the application of these concepts in a project of socio-educational intervention. The analysis also included considerations on this training process from the teacher responsible for the discipline and from coordinators of the Environmental Engineering course. The results indicate that, although a single discipline cannot be deemed responsible for a critical training, the discipline provides significant contributions to the students understanding of EE as a broad, complex, critical and participatory process, mainlyin the sense of allowing a reflection on the deeper causes of the environmental crisis and on the complexity that surrounds proposals to transform such reality.

This research is based on Paulo Freire, Carlos Rodrigues Brandão and Ernani Maria Fiori ideas about education for dialogue, respect and not oppression, known as humanizing education. According to that, authors as HJ Koellreutter, Carlos Kater, Maura Penna and Ilza Joly, help us to defend humanizing education within the field of Music Education. When advocating for humanizing musical education we must also defend the teaching fomation to work within this perspective. Thus, a qualitative research accompanied a group of undergraduate students in music education, which are working with music in public schools through a scholarship program named Institutional Scholarship Program for Teaching Initiation (PIBID). From the framework adopted, the observations made as a music mentor of these students, and the use of a daily field diary, we raised a list of skills and attitudes necessary for an educator seeking to act under the humanizing perspective. The researcher made interventions, and dynamic activities with these undergraduate students to instigate them, to question them, and propose a reflection on their own teaching practice. From these interventions, several pathways and its obstacles were pointed to a teaching formation that aims and cares about the human as a being. During these two years of research, a cyclic pattern was identified regards to how the licensees relates with their job in PIBID. This cycle was analysed from Michaël Huberman analysis about the teaching career cycle, which gave elements to comprehend the teaching experience and their formation. We noticed that to the student become a loving, respectful and dialogical musical educator, therefore humanizing, their formation must be founded in this same principles. This means that the training teacher, who accompainying the undergraduate from the beggining of their program must be loving, respectfull and dialogical. Hopefully, this research will contribute to the field of education and music education, presenting a new concept of music education and showing the necessity and importance of thinking, with commitment and respect, the teaching formation of musical educators to act in Brazilian schools.

Recently, the studies in the area of hybrid materials composed by biological structures have been of great interest, since they are considered versatile biotemplates in wich referred to the organization of nanostructured functional materials, mainly aiming technological attributions. Therefore, the central objective of this Master s Dissertation was the construction of microtubules formed by multilayers combined of gold and silver nanoparticles using as biotemplates the fungus Aspergillus aculeatus, which originated, thus, stable hybrid mesostructures with high potential of application to sensors and biosensors. The fungus was cultivated in a rich environment of citrate and, after the development of the hyphae, the colloidal dispersion of nanoparticles was added. Studies were done with relation to the effect of the synthesis temperature and the concentration of citrate in the average size of the gold nanoparticles and, posteriorly characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and spectroscopy of absorption in the UVVis region. The formation of multilayer composed by different metal nanoparticles was evaluated too. The hybrid materials were characterized by scanning electron microscopy with microanalysis by EDX (SEM-EDS). The obtained results showed that the either concentration of citrate or the temperature directly affect the average size of the gold nanoparticles with expressive results to the temperature. In which referred the formation of the microtubules with different metal nanoparticles, three distinct regions were identified, namely, containing just gold nanoparticles, containing gold and silver nanoparticles and containing just silver nanoparticles, fact discussed in this Master s Dissertation by the differentiation of hyphae growth inside the colloidal dispersion.

Considering the importance of maintenance and continuity of Conservation Units (UCs) and the adoption of strategies for biodiversity conservation in the regional landscape, this study proposes the physical environment characterization associated with the environmental fragility identification of the Passo Fundo National Forest (FLONA-PF), Mato Castelhano municipality, RS, from the perspective of identifying changes in the functions of Management Plan environmental zoning (2012). The physical environment characterization was based on the thematic maps of slope, hypsometry, geomorphology, soils, drainage network and land uses types in 2011, using a GeoEye-1 image with a spatial resolution of 0.5 m and MapInfo 8.5 and Idrisi 32 softwares for data analysis and georeferencing. It was performed a comparative analysis between land use types through 2011 and 2008, to identify the conflicts resulting from land uses changing related to the functions of the National Forest Management Plan enviromental zoning areas, subsidizing decision-making and strategies for their management. The land use classification for 2011, at a hierarchical primary level allowed to quantify and spatialize three typologies: Natural Uses, representing 42.11 % of the National Forest total area, represented by areas occupied by Araucaria Forest (FOM ) in multiple associations that are in various stages of succession and development; Anthropogenic Uses, representing 57.70% of the National Forest total area, whose original features have been modified by human activities, mainly related to araucaria (35.59 %) and Pinus (22.41 %) cultives; and, Aquatic Environments, with 0.19 % of National Forest total area. The analyzes and correlations between inventories in 2011 and 2008, for each area defined in the management plan, revealed diverse typologies in 2011 as a result of image classification methodology used in inventories than by socio- economic influences. About 283.99 ha (22.17%) of National Forest total area presents a scenario of land use conflicts, distributed among the different zones defined in the Management Plan. The use changes for each zone do not compromise the objectives and tasks set out in the Management Plan. Areas with medium environmental fragility predominated (63.22 %), followed by high fragile class (20.42 %). Areas with low fragility occupy only 15.01% of the National Forest. The classes of very low and very high fragility represent less than 1.5 % of the study area. The environmental fragility map with the inclusion of the variable Management Plan zones and the quantification of fragility classes in the areas defined in the Management Plan (2012) indicate that the proposed zoning is consistent with the needs for conservation and recovery in areas of greatest environmental fragility. Comparisons between land use types in 2008 and 2011, along with the environmental fragility to the zones defined in the Management Plan have highlighted new spatial arrangements for FLONA-PF, setting up a study of fundamental importance to reorient meet the goals of the management plan, in addition to supporting environmental planning actions of the regional landscape.

Statistical process control charts (SPC charts) were created in the 20th century in the United States and since then, they have been used for various purposes in different industries and services. SPC chart utilization was widespread in Japan in the postwar period and its effective use in Brazil occurred from the 90´s. Although several examples of use, there are still some industries where deployment of SPC and its sustained use in shopfloor were not successful. In the chemical industry, its use in the shopfloor is controversial and there is no many studies focused on this industry to explain the factors that can impact the successful implementation of statistical control charts by operational teams. This dissertation aims to investigate, through an action research, which are the critical factors for a successful implementation and sustained use of SPC charts in a chemical. It was performed a literature review to gather studies about success factors to implement SPC chart in industries. Using action research, those critical success factors were tested in practice with operators in the chemical plant of a multinational enterprise located in Brazil. This chemical plant has experimented to implement SPC chart in the past with no success. As a result of the action research, we succeed to implement SPC chart in the industrial unit and reduce variability with savings of US$ 150,000.00 per year energy. SPC chart use was well received by operators and leadership, showing that some success factors are really critical for a correct SPC implementation in a brazilian chemical plant. The results were used to develop a roadmap for SPC, with details about how and when to work each success factor. Afterwards, Roadmap was used in another eight different industrial units of the chemical company, all with success.

The monitoring of indoor air quality (QIA) is a subject that has been disseminated in the current research. The objectives of them are the development of common methodologies to identify possible pollution agents at different locations. However, there are few works that develop methodologies in an attempt to mitigate the effects of indoor air pollution. Based on this problem, this study aimed to evaluate the effectiveness of filters doped with silver nanoparticles in the elimination of bacteria and fungi (bioaerosols) present in particulate matter from indoor environments, since it is known that nanosized silver particles have pronounced bactericidal and fungicidal effect. To achieve these goals, fabrics considered common were initially acquired in malls and were evaluated in terms of their filtration properties (permeability, loss, collection efficiency). It was subsequently performed the synthesis of silver nanoparticles suspension followed by immersion in the suspension of the chosen fabric. After drying, they were used to collect air suspended particulate material in a bathroom of the Department of Chemical Engineering of the Federal University of São Carlos. From the results it was verified that the filters doped with silver nanoparticles were able to significantly eradicate microorganisms present in air suspended particulate material. The elimination of microorganisms ranged from 22 to 82% for the mesh PV and 71 to 100% for the cotton fabric.

The increase in demand for biofuels has driven the development of new technologies such as ethanol production from sugarcane bagasse hydrolysis. Given the importance of Brazil in the ethanol market, the inclusion of technology of second generation ethanol will intensify its production. Energy integration in a sugarcane biorefinery provides important advantages for industrial processes such as better energy management, environmental benefits and increased ethanol production. The last factor is due to lower steam consumption in plant with energy integration, so, less bagasse is needed for cogeneration and a fraction of the surplus can be made available for production of second generation ethanol. In this context, the present study conducted energy integration of a sugarcane biorefinery in order to reduce the consumption of utilities. The technique used was Pinch analysis, an established methodology in the area of energy integration. The biorefinery used in this work consists of process for first and second generation ethanol and electricity production simulated in EMSO software (Environment for Modeling, Simulation, and Optimization). Six different scenarios of biorefinery were evaluated, which differ by pretreatment for bagasse (hydrothermal, diluted acid and steam explosion) and by inclusion or not of pentoses fermentation step. Processes that consider pentoses fermentation step have higher ethanol production when compared to processes that do not make use of pentoses fraction, but steam consumption increases in the same order of magnitude of ethanol production. For the six scenarios evaluated energy integration demonstrated a reduction in energy consumption over 50% when compared to corresponding processes without energy integration and over 30% when compared to process with project integration, as commonly found in Brazilian plants. Besides the economic advantage due to decreased costs of hot and cold utilities, the energy integration provides better energy management, reduction in emission of gases and liquid effluents and increases the availability of bagasse for production of second generation ethanol and/or electricity.

O objetivo desta pesquisa foi analisar se e de que maneira o Programa de Mentoria online, oferecido pela Universidade Federal de São Carlos (2004-2007) contribuiu para a formação de professores iniciantes, participantes da iniciativa, a partir da análise atual desses docentes sobre sua participação no programa. Ele foi desenvolvido com o propósito de auxiliar professores com menos de cinco anos de carreira a superarem as dificuldades típicas dos anos iniciais da docência, por meio do seu acompanhamento, via correspondências eletrônicas, por professoras experientes as mentoras. O referencial teórico pautou-se na literatura sobre professores iniciantes, aprendizagem e desenvolvimento profissional da docência, base de conhecimento para o ensino. Os dados foram coletados por meio de um questionário online preenchido por dez professoras ex-participantes do Programa e por entrevistas semiestruturadas, realizadas via Skype com duas delas. Além disso, as análises envolveram os dados obtidos durante a realização do Programa, considerados aqui como narrativas. Os resultados apontam o início da carreira como um momento caracterizado por angústias, inseguranças e desespero, como também por falta de apoio na inserção do professor no contexto de trabalho. Apontar também que a participação no Programa de Mentoria promoveu aprendizagens, mediante interações entre com as mentoras, que ajudaram no enfrentamento das dificuldades vivenciadas nos primeiros anos da carreira, assim como após cinco anos de exercício profissional.

The ATiO3 (A = Pb, Ca, Sr, and Ba) perovskite have attracted considerable attention and constitute one of the most important class of mixed oxides. It presents various applications owing to their physical properties and has been extensively studied as candidates for electro-optical devices. Pure Calcium Titanate (CT) and Samarium doped Calcium Titanate Ca1-xSmxTiO3 (x = 0,5%, 1,0%, 3,0% and 5,0% molar ratio of Sm3+ ions) powders were synthesized by hydrothermal microwave method (HTMW) at 140 °C for 16 min resulting in the samples CT:Sm (0,5%), CT:Sm (1,0%), CT:Sm (3,0%) and CT:Sm (5,0%), respectively. The HTMW method appears to be an efficient method to prepare the luminescence materials using low temperatures and very short reactional times. Sm3+ ion was introduced into the perovskite lattice aiming to study the synthesis, photoluminescence emissions and morphological properties of these powders. X-ray diffraction (XRD) patterns present a single phase indexed as Pbnm space group in a typical orthorhombic CaTiO3 (CT) structure which prove long-range order. Micro-Raman (MR) spectra of the samples indicated the characteristics vibrational modes, while UV-vis measurements showed changes in the optical absorbance behavior of CT samples compared to CT:Sm. The existence of two small absorbance bands at 406 and 603 nm suggests the presence of Sm3+ in the CT lattice, confirmed by excitation and photoluminescence emission spectra. Photoluminescence (PL) spectra show Sm3+ emission lines ascribed to the Sm3+ transitions from 4G5/2 excited states to 6HJ (J = 5/2, 7/2, 9/2 and 11/2) states in CT:Sm powders excited at 406 nm, that was noticed at, respectively 567, 603, 648 and 713 nm. Among the samples, the most intense photoluminescence results were observed for the CT:Sm (1,0%) sample. Field Emission Gun -Scanning Electron Microscope (FEG-SEM) showed micro-cubes shape with dimensions around 3,0 μm and were not affected by the Sm3+ concentrations considered here. EDSX results confirmed the composition of the samples. The Commission International d Eclairage (CIE) chromaticity coordinates of the as prepared CT:Sm samples were determined and confirm these materials as promising candidates for applications in the visible red-orange range spectra.

The Motion Capture technology is considered a potential to overcome the limitations of traditional human simulation, reducing the time spent on creating and assigning greater reality simulations the simulated movements. This research presents an analysis of a technical system, formed by integrating a Motion Capture System with a human model and simulation software, aiming to establish ways to use the system in project process, contextualized by ergonomics. Different configurations of the main steps of the integration of the Motion Capture System Moven (Xsens), integrated with CAD DELMIA (Dassault Systèmes) software, which has a module of human simulation (Human Builder), through four experimental tests. Four trials were defined with factorial design to test the combination of different possible system configurations: i) spatial positioning of virtual environments, ii) mitigation of drift, iii) digital human kinematics and iv) anthropometric compatibility. From the results obtained in each test operating procedures were constructed in order to solve the problems and limitations of using these integrated technologies. The following procedures show how to configure the integrated system for positioning a virtual environment in a CAD system known coordinates, which enables the correction of the position due to drift of the capture system. Procedures that relate to the possible interactions between the body and capture the workplace, with the characteristics of the activity and the objectives of the simulation were also created. In addition, it was elaborated a systematic iterative to match the anthropometry between real human being, avatar of the capture system and digital human. The development of ways to use these technologies provides improvement of techniques used to construct the simulation, contributing to integration the perspective of future activity in the design in the design of productive situations.

This study discusses the stage of demand assessment of a corporate ergonomic program from a big company in the mechanical metal sector of high aggregated value. The topics covered in this work present the approach, methodological grounds and tools used in the Active Search for ergonomics issues. This Active Search is a systematic approach for mapping ergonomic demands developed and applied in the case presented. This approach encompasses a procedure and software which will be presented in this work. The Active Search begins after the analysis of medical related absenteeism data. They indicate the sectors where there may be critical situations in which ergonomic intervention is needed. After that, the required tasks are identified for each sector. Those tasks are analyzed by workers who, individually, indicate the ones that are critical and, among these, they also study their level of criticality in a preestablished scale. Finally, the data are compiled and submitted to the validation and prioritization of workers. The process is a collective activity which involves all the workers of the sector and the supervisors. Later, the selected activities are sent for the ergonomic situation analysis. This is an action research grounded study. The results of this work have shown a method which helps the identification of the tasks considered critical by the workers and that helps in the synthesis of the collected data. The relations among demands for family and products; ergonomic demands from technology used in manufacturing; the production sector and its respective directors and single manufacturing units are presented in the moment of synthesis. In the view of the results for such synthesis, it is possible to identify the distribution in the company of the ergonomic demands, according to these categories. This can aid the organization to decide the strategies to reduce critical work situation and to determine the systematically operations of the action analysis as well as the ergonomic improvements for the project. In addition, other results of this study are presented as an approach in the analysis phase in the ergonomic demand, as an operant model and as a technological innovation.

Based on the concepts of experience and Walter Benjamin's living, the present study aims to construct and investigate a proposed curriculum in sciences based on the pedagogy of Paulo Freire, aiming at the possibility of providing humanizing experiences, which in the context of the classroom, are able to contribute to a education greater social quality and to overcoming some difficulties related to science teaching. For this purpose, from a qualitative methodological approach, identified with the theory of action research, were conducted participating observations and constructed a plan of action, that constituted himself in a programmatic sequence for science teaching in the context of a public school the municipal education of Sao Paulo. This sequence had how theoretical and methodological referentials: the process of thematic research via generator theme as proposed by Paulo Freire, the thematic network by Antonio Gouvêa da Silva, and the three pedagogical moments influenced by Freire's pedagogy and suggested by Demétrio Delizoicov, José Angotti and Marta Pernambuco. Data obtained during this process constitute in the students' productions, collected and organized for later analysis, and records kept by the teacher-researcher in the field diary. The analysis of the data was under the light of freirean thinking and in benjaminianos concepts of experience. The curricular experience made possible positive changes, in ethical and critical perspective, in the form of learners interpret and position themselves through social reality which points to the possibility of humanizing experiences through a freirean curricular practice. And while promoting contextualized practices, dialogical, problematizing and participatory practices showed possible advances in overcoming some of the difficulties encountered nowadays in science teaching.

The purpose of this paper is to discuss the operations strategy in a health care company located in São Paulo State: it s content, associate with established competitive priorities, and the changes in the structural and infrastructural decisions areas. The literature review shows that the discussion about operations strategy in service area is not exhausted; services have specific characteristics, as direct contact with the customer and the almost simultaneous interference in this process and that differs services operation from manufacturing operation. A secondary health area data analysis allowed the construction of the economic and market environment, in which companies that operate in the provision of health services are inserted: there are annual increase in search for private services, but the market has become more concentrated; barriers to entry and the operation of a regulatory agency are also factors that affect the performance of the companies. The studied company has diversified operations and significant area; because of the personalized service that provides, and competitors with administrative and financial problems, the case is the market leader. Quality and service are the explicit competitive priorities, but the regulatory agency requirements also guide the operations. The search for service pattern recognition, with ONA certification, the organized quality team, the improvement of customer service and the dispersion of the facilities are actions that have been implemented by the company and confirm the alignment between their competitive and operations strategies.

The integration of technological resources in teaching and learning process assigns to education a need for new thinking and sets new challenges to the routine of the classroom, leaving the teacher to review practices and concepts confront this issue. Given this situation, we conducted a qualitative research, as Lüdke and Andrew (1986) through a case study in a public school in the city of São Carlos - SP, with two active teachers in elementary education from the early years, with in order to answer the following question: What ideas have influenced the organization of pedagogical practices with technological resources of teachers in the early years of elementary school? Data were grouped into two angles: 1) the design of technological resources for teachers; and 2) Characterization of teaching practices with the use of technological resources. Our analyzes received theoretical background , mainly from Maurice Tardif , Maria Luiza Belloni , Vani Kenski Moreira , Vieira Pinto , Lion , Bernadette Gatti , Marcelo Garcia. Generally the teachers investigated using resources such as radio and television, which are dominated by them. Resources such as computers and data projectors are used by teachers with more fear; since these are equipments that they do not dominate. These and other aspects lead us to realize the importance of training teachers to use technological resources in a way that leverages the educational process, promoting student learning. Yet conducted a bibliographic study on digital database of thesis and dissertations to articulate the data found by analyzing the concepts and practices of the two teachers.

Background: Frailty is a critical state of physiological complexity loss. Evaluation measures of complexity could contribute for a better comprehension regarding the frailty process. Objective: to evaluate complexity of HRV, at rest and after postural change, on frailty syndrome. Design: cross-sectional. Setting: community. Subjects: 100 individuals over 60 years old, distributed in groups according to the frailty phenotype: frail (n=8), pre-frail (n=46) and non-frail (n=46). Methods: The electrocardiogram was made in supine and orthostatic postures, for 10 minutes in each position. Sequences of 256 RR intervals were analyzed through linear (spectral analysis low frequency in normalized units (LFnu) and high frequency in absolute units (HFabs)) and non-linear methods (symbolic analysis 0V% and 2UV%, Shannon entropy (SE), conditional entropy (normalized complexity index NCI)). Results: The NCI did not show difference among the evaluated groups in rest supine, however NCI presented reduced values in all 3 groups after orthostatic challenge. Except AFabs, other indices did not differ between groups at rest supine. Conclusion: The results of this study indicate that there is no decrease of complexity on frailty syndrome, possibly because it already presents decreased values with the senescence. The postural change was unable to detect any impairment in HRV complexity associated with the frailty process.

The main aim of this dissertation was to understand the perceptions of the educators involved in an investigation about the possibilities and importance of the use of visual culture images in the educational process within basic school spaces. The nature of the research was qualitative and exploratory. The empirical part was started by an extension course, a partnership between the Federal University of São Carlos and the local state school educational bureau, named: Image reading for medium and high school. Teachers lecturing at the four main areas of the national curriculum participated in the course. There were also school principals and pedagogical coordinators. From this group of educators, seven were selected to participate more directly of the investigation. The data collected were analyzed by the content analyses methodology, in which some aspects stood out, the ones we considered the obtained results: the cognitive development of the students and the application of specific school content has been one of the main image work objectives in the participants classrooms; such utilization occurs as a critical pedagogy strategy, directed mainly to perceptions of media influence; the school books available images have not been explored in all their possibilities, as knowledge facilitators and articulators towards critical attitudes; there is a content theorization need in critical perspectives, besides the thought diversity, fostered by collective appreciations of several images and artifact belonging to the visual culture, allowing the comprehension of plural thought importance and the difference concept, which may produce new basis to build a more democratic and inclusive basic school.

One witness a world in which a company, to survive in a increasingly competitive market, needs to lauch new products in a dwindling time. To reach this, the company needs to acquire technologies, knowledge, skills and abilities through the innovation in both products and processes. In this context, there are the technology parks, that are physical spaces where it happens technology, innovation and information sharing. A technology park works as a mechanism for business: there are technology-based companies, business incubators, universities, research institutions, higher education institutions and research laboratories. Thus, it creats a propitios environment so that there are relationships between companies and universities, or, in other words, academic knowledge becomes a part of the daily business and it develops itself in innovation that can be marketed. So that the park can achieve it goals and develop and disseminate technological processes it needs to establish strong links with government institutions, compnies that complies with its objective and universities that are able to provide academic knowledge. This study aims to determine whether the presence of a technology park encourages the creation and development of academic spin-offs in São Carlos city (SP). It was a multi case study in São Carlos Science Park and Parque Eco Tecnológico Damha-São Carlos. As the mainly results, it was possible to note that having two technology parks in the city was not enough to stimulate the creation of academic spin-offs, but it is enough to maintain and develop the spin-offs that already been created. Besides, it was possible to note that the entrepreneurs miss the incentive from the university to create academic spin-offs and to create links with incubators and technology parks.
