The subterranean fauna from Brazil is the best studied in South America, and most of the publications come from caves in limestone rocks. However, the national territory also includes areas of quartzite rocks, sandstone, granite and iron ore with great speleological potential. Thus, the present study aimed to describe the faunistic composition of arenitic caves in the municipality of Altinópolis state of São Paulo state. We found 131 morphospecies, most of them belonging to Class Insecta (89 morphospecies) and Class Arachnida (31 morphospecies). This fauna corresponds with the fauna found in previous studies in this region and in other studies in the same lithology. The fauna is composed mainly of spiders (Pholcidae, Ctenidae and Sicariidae families), and their possible prey as cockroaches (Blattaria), crickets (Orthoptera), mosquitoes (Diptera), beetles larvae (Coleoptera) and moths (Lepidoptera). In the light reaction tests, the eight taxa studied were significantly photonegative for all light intensities (150, 500 and 1000 lux). Photophobia can be considered a plesiomorphic character state for the group, which is related apparently to the eye patterns (number of ommatidia and ocular area). The Pseudonannolene population from Olho de Cabra cave had low population densities on the four monitoring occasions, with the individuals found mostly in the twilight and aphotic cave zones. The low population density can be attributed to the low concentration of calcium in the soil of the region and, consequently, inside the cave. The effect of seasonality was marginally significant, probably due to the low population density, which may be a consequence of the stress caused by the atypical drought of the last years (2013 and 2014), so that this population is still reestablishing itself. Studies that approach the diversity and biological aspects (e. g. population and behavior) are important to determine relevance of the cave for conservatiom purposes. The present study contributes to the knowledge of the diversity of the subterranean fauna from Altinópolis, and approach the phototactic behavior and population ecology of the subterranean millipede Pseudonannolene never studied before.

Poor childhood and adolescence has undergone a social stigmatization process taking a cultural imaginary status as “dangerous” and “violent”. Brazilian Government has developed controlling and contention tools as a response to the involvement of adolescents in infractions. The Statute of the Child and Adolescent (Estatuto da Criança e do Adolescente – ECA) has made it possible to give these tools a punitive formal profile, in the juridical text, working on socioeducation, and blaming the adolescents, families, and society. Within this context, the present study aimed to know the expectations from juveniles regarding the process of quitting the internment, as well as learning how its routine goes on. The study was at two foundations where the appropriate socioeducational matters of privation of liberty were performed, in two different states of Brazil, being one in a medium-size city, and the other in a metropolis. Thus, during the first stage, 22 workshops meetings were carried out with 59 adolescents, aiming to know their expectations regarding quitting the foundation, and they were also invited to take part into the second stage. Nine semi-structured interviews were also done with technicians involved in their follow-up, focusing on strategies used to plan their reintroduction to the community. In the second stage, territorial follow-ups were performed, for four months, with four adolescents who were interned in socioeducational privacy of liberty in one of the cities mentioned before, aiming to understand how their return to the community was. By using the data obtained from the foundations, and together with the teenagers in their communities, we were able to understand that those adolescents were subordinate to criminal subjection social process, by creating the social expectation which bonds them to the identity of criminals, highly highlighting them to the possibility of communal bonding. It was concluded that besides the strong tagging of this process, and the exclusion from the daily life they face, since their internment the adolescents aim to build resistance and life spaces in their routines.

The present thesis is described in research papers format, whose development is justified by literature review, phase of intervention tests to improve the plans of data collection and data collection itself. PROPOSAL 1 (Literature review) composes paper 1 and along with paper 2 present the synthesis of the analyzed variables, evaluation and intervention forms and the main results of cognitive-behavioral intervention studies on people with chronic pain, whose results helped in the conduction of the following studies. PROPOSAL 2 (Pilot study) presents a study aimed at women with fibromyalgia (FM) and poor sleep quality, whose research design allowed to evaluate: the effects of a brief behavioral intervention for pain and sleep combined with a relaxation training, and the isolated effect of relaxation training, both compared to the control group without intervention (paper 3) and the effect and order of application of the two components (pain and sleep management) of this intervention (paper 4). And, PROPOSAL 3 (Data collection) corresponds to the study conducted to women with FM and insomnia, from Multiple Baseline Design with withdrawal of the intervention and pre and post test evaluations, which was split in two articles: one of them evaluated the effect of two components of a behavioral intervention for pain management (1 - management of the physical environment conditions and 2 - interpersonal relationship management), on pain and sleep indicators (paper 5), and the other evaluated the effect of this intervention on other health indicators, besides clinical significance and reliable change (paper 6). Direct self-report and self-registration measures for pain and/or sleep assessment were considered in all intervention studies. Data showed that the brief analytical-behavioral intervention (pilot study) for pain and sleep had an impact on reducing the intensity and incapacity of pain and anxiety, and the intervention for pain (data collection itself) had an impact both on pain and sleep, anxiety, depression, stress and social skills self-reported indicators. Considering the direct measures, both studies (pilot and data collection) showed a change in the sleep pattern (mainly sleep latency) evaluated by actigraphy, but there was no change in the Cortisol Awakening Response (CAR). The present study results are in line with the literature, and methodological aspects were discussed.

Siblings of people with ASD could develop social and emotional problems, also, they could have difficulties in parental relationship. Group intervention could be a way to support those siblings with typical development on clarifying their doubts, sharing experiences, and learning strategies to deal with their ASD siblings’ daily relationship. The goal of this study is to present a report of a group intervention with ASD siblings and its effects upon these variables: behavior issues and social behavior; stress and confrontation strategies; relationship network and knowledge about ASD, in addition, the parents and caregivers’ satisfaction related to the intervention. The design used was a quasi-experimental design with three groups: experimental group (EG) which received the whole intervention, partial group (PG) which received a partial intervention, and control group (CG) which did not receive the intervention. There were pre-and post-test to all of the groups but a six months follow-up only with EG. The EG participants were six siblings with age ranging from10 to 15 years old, PG participants were four siblings with age ranging from10 to 12 years old, and the CG participants were four siblings with age ranging from 8 to 12 years old. All the groups had participants with both genders. There were five meetings with EG (12 hours total) and three meetings with PG (6 hours total). Emotional aspects and information were developed in these meetings. In total, 15 siblings and their parents and caregivers participated of the research. One child participated only of the pre-test stage. The protocols used were Strengths and Difficulties Questionnaire (SDQ), Stress and Coping in Siblings, Network of Relationships Inventory (NRI), Childhood Autism Rating Scale (CARS), satisfaction questionnaire with every meeting activities, and a parent /caregiver questionnaire, two semi structured interview scripts, one was used with the research participants, and the other with parents and caregivers. The results showed positive changes related to ASD knowledge, confrontation strategies optimization and for the two intervention groups, a pro-social behavior improvement. There were not changes related to difficulties, stress and relationship networks. The participants reported they enjoyed the activities, so did their parents and caregivers related to the intervention. For future studies, it would be important to consider a large intervention time and the number of participants. Also, a statistical analysis should be considered for future studies to check if the changes were significant to correlate them to gender, birth order, ASD level and the results of the protocols used. Parallel Interventions with ASD parents and siblings could be an interesting possibility. Besides the research limitations, this is a pioneer study in this country. It has showed the importance of a place where the ASD siblings could be heard, received information and support, because they could be benefited from professionals’ attention. Group intervention is beneficial when considering experience changes and time and resources optimization. But also, there are specific cases, especially when high stress levels and disruptive behaviors are presented, that individualized attention could be essential.

In Brazil several works were carried out considering a general diversity of underground organisms from different regions. The Parque Nacional Cavernas do Peruaçu (PNCP), near the municipality of Itacarambi, Minas Gerais states, highlighted by works carried out with the troglobite catfish (exclusive of subterranean environment) Trichomycterus itacarambiensis Trajano and Pinna (1996), the end of the Olhos d’ Água cave. In addition to catfish, a cave is home to other populations of troglobites, such as the harvestmen Iandumoema uai Pinto-da-Rocha (1996) and the whip spider Charinus eleonorae Baptista and Giupponi (2003). The populations of the Eusarcus cavernicola Hara and Pinto-da-Rocha (2008) and Eusarcus aduncus Mello-Leitão (1942). Considering the populations of the mentioned arachnid species, we investigated from the marking and recapture method as size and population density. In addition, we analyzed the distribution of the troglóbios (I. uai and C. eleonorae) in relation to troglófilos (E. cavernicola and E. aduncus). Finally, from collections made in caves of the PNCP analyzes a diversity of the subterranean fauna in relation to Olhos d 'Água cave. Our results showed that the population of I. uai opium is numerically higher than others, with population values and higher densities. In addition, I. uai widely distributed in the various regions of the Olhos d 'Água cave, as well as C. eleonorae. In contrast, E. cavernicola and E. aduncus are restricted within the cavern with populations secreted relative to I. uai and C. eleonorae. Still, the Olhos d 'Água cave presents greater subterranean diversity with occurrence of troglophiles, troglóbites and relict specie.

This work is a theoretical effort that aims to give light to a debate about the formation and development of a paradigm into scientific knowledge. More specifically the proposal is to analyze some aspects about how the scientific institutions, understood as the rules, the organization and the structure, develop a new paradigm. To reach the objectives of this work, we will analyze the case of Agroecology, a self-titled new science with a new paradigm. In order to give an account of our case study, we have based the social studies of science from the writings of Thomas Kuhn and Pierre Bourdieu, given basis to the concepts of paradigm and social fields, that we use to analyze agroecological field, and the scientific field. The paper analyzes the science, based in social analyzes of science, and the formation of the agroecological field, trying to understand what are the assumptions that compose it as a new paradigm. With this in hand, the paper analyzes the adequacy of this field to the national scientific institutions, identifying how the teaching and research is composed at the existing rules for universities and research institutes, for which analyzes two cases, in undergraduate, and three postgraduate studies. From this analysis, the work concludes that this adequacy tends to provoke a predominance of some areas of knowledge towards others, reaching some of the assumptions of the paradigm in question.

The financialization process made the shareholder value ideology become the main guiding principle of corporate behavior, which resulted in several changes in the organizations, for instance, in the profile and way the managers operates and in the strategies and management practices adopted. In this context, the approaches of quality management, which focus on providing superior value to the customers, had to adapt to maintain its legitimacy towards the shareholder value ideology. In this sense, this thesis aims to explore the influence of the elements of the management based on the financial logic in the National Quality Award, which is one of the most contemporary approaches of the quality management. The relevance of this study, due to the fact that there is a few empirical studies that analyzed the influence of financial logic in quality management approaches and in Brazilian organizations. In order to reach the described objective, an exploratory study was carried out based on secondary data, from a documentary research. This included the analysis of the existence of elements of the management based on the financial logic in the versions of the Management Excellence Model used by the National Quality Award and in the 66 companies that won the award between 1992 to 2016. The results point out the influence of financial logic in the National Quality Award. The analysis of the versions of the Management Excellence Model demonstrated that concepts of financial logic were gradually being incorporated instead of practices related to the quality management. The analysis of the profile of the companies that won the National Quality Award showed that 36% of the companies were awarded post-privatizations, which ocourred in the 1990s, with the predominance of companies of eletric energy segment. The analysis of the executives showed that members of the top management of more than 20 winning companies have acted on the boards of the National Quality Foudantion contributing to the formulation of the award guidelines. In addition, it was verified the existence of board interlockings in the winning organizations, which favored the dissemination of the Management Excellence Model and the National Quality Award. Finally, the analysis of the profile of the presidents of the winning companies demonstrated the predominance of executives with professional background in financial areas and post-graduation in finance, which are valued by the finance conception of control. This thesis indicated the reconversion of the the National Quality Award towards adherence to the management discourse based on the financial logic due to the need to maintain its legitimacy.

This dissertation deals with the study of the influence of void geometry on the shear capacity of prestressed hollow core slabs. Based on analytical models for the tension shear capacity for uncracked sections, which were first proposed by YANG (1994) and latter modified by PAJARI (2005), a calculation procedure applying spreadsheets has being proposed for the prior definition of the void geometry, allowing an easy and quick way to evaluate the efficiency of the void shape to provide shear capacity. In addition, the influence of the variation of the angle of failure for the tension shear mechanism has been confronted against experimental results, giving indication that the fixed angle of 35º assumed by YANG (1994) is an adequate inclination to be considered in design. Calculation examples were presented in order to elucidate the main concepts discussed in this work. Comparisons were made considering the Brazilian normative model and the Yang-Pajari model for tension shear, from results obtained experimentally for prototypes whose rupture occurred by diagonal traction, and for the Brazilian standard model, safety results were not verified for slabs with oblong cores; as opposed to the YANG-PAJARI model applied to the same slabs, providing satisfactory results. In addition, the analytical model based on the Brazilian code of practice for structural concrete has been verified against experimental results for slabs with oblong cores, wherein some of the experimental results were found below the predicted values. However, as the number of experimental results was small, future experimental investigation is needed in order to verify the reliability of this analytical model.

Being a global phenomenon, the motorization process has advanced in the last decades and is characterized mainly by the increase of motor vehicles used in the individual transport. The evidence suggests the association of the process with the deficiencies of public transport, the model of urban land occupation and the economic policies to encourage the automobile industry in recent decades. In view of the aggravation of the national scenario, the new guidelines of the National Urban Mobility Policy were instituted in 2012 with the purpose of encouraging the use of collective transportation and non-motorized modes. In spite of representing an innovation, with admittedly positive propositions, several questions are raised, especially regarding the financing of infrastructure and the sharing of the costs of public transport and other initiatives aimed at urban mobility. The new legislation did not give due attention to motorcycles, as it saw them under the same conditions as cars and other motor vehicles, despite their recognized vulnerability. This is the reason why small safety initiatives in the use of this type of vehicle are important. It was verified that some parking spaces for motorcycles available on the campus São Carlos of the UFSCar have reduced dimensions or some difficulty for their access, besides the disproportionality in front of the offer of vacancies for the automobiles. The hypothesis was then formulated about the outdating of the parameters used in the distribution of the vacancies, dimensions and in the maximum slope of the floor, particularly in parking lots positioned outside the streets. The bibliographic review was applied to collect propositions regarding these parameters. A questionnaire was also sent to the municipal transit authorities, which allowed verification the criteria for the deployment of new parking lots. The case study was used to analyze the adopted parameters and was inferred by the veracity of the initial hypothesis. It was also verified that in the majority of the studied cases the size of the vacancies do not follow the recommendation of the regulator of traffic. It was found that the distribution of parking spaces between motorcycles and automobiles does not correspond to the proportion observed in the municipal, state and regional vehicle fleet. It was concluded that the specificities of the motorcycles were not considered in relation to the inclination of the floor of the parking lots. Based on the information obtained during the research, the proposals for adequacy for UFSCar parking lots were made.

The cities are under a process of constant expansion, which generates degradation of the natural system. However, economic progress and the cities growth depends on the stability of ecosystems as a way to supply resources for human activities. Some urban planning models and approaches were designed in different contexts and scales as a way to build more harmonious cities within their natural environment, also to compose a set of inspiring theories and practices to promote advances in this scenario for the Brazilian cities. In the search to match the development of urban systems and the balance of natural ecosystems, this research aims to structure criteria and guidelines to guide the development of reduced environmental impact urban projects. To analyze this potential, it is suggested their application in peri-urban expansion zones of São Carlos (São Paulo State). Additionally, urban instruments and regulations will be analyzed regarding the potential application of the proposal, through a research protocol. For the criteria and guidelines by itself, it is expected that a critical analyze of its application could, in some way, contribute to the development of reduced environmental impact in urban projects.

Aluminum sheets are produced by rolling followed by annealing. However when submitted to deep drawing earing appears, caused by the plastic anisotropy resulting from the production process. After annealing the main texture is cube {001} , that is recognized as being the cause of this heterogeneity during deep drawing. The literature shows that when shear stress is applied in the deformation process, it leads to texture changes. In this study asymmetric rolling (AR) was used as a technique to produce shear. The shear stress is introduced by the different velocities between the upper and bottom rolls and in this study this was achieved by using roll radius relations (r1/r2) of 1,5 and 2. Rolling reductions of 50% in thickness were applied to aluminum AA1050 sheets. The conventional rolling (CR) was compared to the asymmetric rolling (AR), at two different reduction rates: 5% and 10%. The crystallographic textures were obtained by xray diffraction. Finite element analysis, using the DEFORM software, was used to analyze the effective strain distribution throughout the thickness as well as its components: normal strain, shear strain and rigid body rotation. The samples were annealed in a furnace with 350°C for 05, 10, 15, 20 and 60 minutes. The microstructure was characterized by optical microscopy, electron back scatter diffraction and x-ray diffraction. The plastic anisotropy (Lankford Parameter) was measured by tensile experiments at three different sheet directions and by the Erichsen test. The deformed samples’ microstructure was analyzed at the surface near to the upper roll and at half of the thickness. For the CR the main components were brass (Bs) {011} , Goss (Gs) {011} and copper (Cu) {112} , with 8.8 intensity at the central layer, and 4.5 at the surface. For AR samples the was more random at the surface of the samples with 5% of reduction per pass, added to a component of rotation in the normal direction, what resulted in cube and rotated cube textures or near to these orientations, generating a type of fiber {100}//ND. The maximum intensities for the (r1/r2) of 1,5 and 2 were 3 and 4, respectively. For the samples with 10% of reduction per pass the rolled texture was still presented, with a more intense rotation in the transversal direction related to the rolling direction and shear texture components {100}//ND and . The maximum intensities were 3 and 3.5 , for the (r1/r2) of 1,5 and 2, respectively. In the center layer of the samples with 5% of reduction per pass for (r1/r2) of 1,5 and 2 showed a intensity of 5.26 and 6.56, respectively and the strongest shear texture was rotated Goss (C). (011)[0-1- 1] The samples with 10% reduction per pass showed the greatest reduction of intensity with 3.05 and 3.63, for the (r1/r2) of 1,5 and 2 respectively, and the highest intensity was related to rotate the Goss (011)[0-1-1] component. In the pole figures rotations around the transversal direction (TD) and the normal direction (ND) were observed. Using the finite element analysis the rotation around the TD and ND were quantified and its variation across the thickness were analyzed. The rigid body rotation is superposed to shear , which leads to the observed texture gradients. The rotation around TD is imposed by the velocity difference between top and bottom roll, whereas the ND rotation is imposed by the experimental configuration, which permit variation of the sample alignment at the roll mill entrance. This was stronger for the 5% reduction rate and more concentrated at the samples surface. After 05 minutes the annealed samples were already recrystallized , after 60 minutes the grain average size was 30µm, and hardness 21HV. The annealed texture for the CR sample showed the greatest concentration off Cube texture {001} and intensity of 8.08 times the random. For the AR samples with 5% reduction per pass the intensities for the (r1/r2) of 1,5 and 2 was 5.88 and 6.56, respectively, and for the 10% reduction per pass 2.96 and 2.85, respectively. The AR decreases the annealed texture. In the samples of 5% reduction per pass the most intense shear texture was rotated Goss, the 10% reduction per pass did not have a predominant component. The Lankford parameters showed less anisotropy for the annealed samples with 10% reduction per pass. Based on the values of anisotropy and hardening exponent for each sample, the Limiting Rate of Drawing was calculated. The AR got a superior values than the CR ones, indicating an improvement of the drawability.

Porous anodic alumina can be obtained, in addition to conventional methods such as potentiostatic and galvanostatic, or by pulsed method. Among these are the methods of discontinuous pulse, hybrid pulse and polarized pulse methods. The structures formed by these methods can be applied to sensors and photonic materials. In this work the influences of the pulse parameters for the porous anodic alumina were investigated by polarized pulse potentiostatic anodization. Data analysis was presented from the duty cycle seen in the literature, which provides important information about the structure formed for the applied conditions and, in addition, new ways of analyzing the data related to the pulse, such as the analysis of the potential difference and the pulse frequency, this latter complementing the analysis of the duty cycle. As a result it was possible to observe that the porous anodic alumina thickness obtained is proportional to the duty cycle applied, where the higher duty cycle, the greater the thickness obtained. From the potential difference, the differences in the morphological and optical parameters could be analyzed by the influence of the negative minimum voltage applied during the pulsed anodization. The pulse frequency, also discussed in this work, was used to analyze different pulse periods for the same duty cycle, demonstrating that can be obtained structures with different values by varying the value of the pulse frequency. For the porosity calculation, an application was developed that helped to obtain the pore distance, which is one of the variables used to calculate the porosity. With the porosity values, the effective refractive index of each sample was calculated to find the effective optical thickness (EOT) and, finally, the thickness of the obtained anodic alumina film.

The productive chain of the alembic cachaca is one of the most promising in the developing agroindustry in Brazil. The vinasse is the main waste of the productive activity, due to the large volume generated. The environmental dynamics demands the reuse of industrial wastes, but such use may lead to situations of environmental pollution when the wastes are poorly handled or applied in excessive amounts. In addition, there are a few studies that evaluate the composition of vinasses derived from the production of cachaça and its suitability to the fertigation. In this context, the present work aimed to evaluate the influence of the sugarcane management and variety on the composition of the vinasse from alembic cachaça. A randomized block design was utilized in a factorial 3X3, with three varieties (RB867515, RB966928 and RB855453) and three cane managements (conventional, organic and control). The experiment had four repetitions for each management and variety, with 9 treatments and 36 parcels in the totality. The samples of vinasse were evaluated for pH and concentrations of macronutrients and micronutrients (Carbon, Nitrogen, Carbon/Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Iron, Copper, Manganese and Zinc). The results were submitted to analysis of variance (ANOVA) and when differences were significant, Tukey´s test was applied by using Assistat program. There was significant effect of the management (organic and conventional) only on three elements of the vinasse composition, C, K and Mg, the highest concentrations were observed in the vinasse coming from conventional cane management. Regarding cane variety, there was significant effect only on Ca and Mg in the variety RB867515 and RB855453, respectively. The conclusion is that the sugarcane management and the variety had a little influence on the vinasse composition from alembic cachaça. The vinasse composition varied more in accordance with the conditions of distillation of the fermented must for the production of cachaça. The vinasses obtained in the present work, regardless the cane management and variety, presented composition rich in macronutrients and micronutrients when compared to the cachaça or ethanol vinasse compositions reported in literature, featuring N, P, K, Ca, Mg, S, Fe and Cu.

In this study, the synthesis of phthalocyanine derivatives with extended conjugation were proposed. In order to obtain these compounds, two main strategies were applied. One of them, was the Heck-Mizoroki cross-coupling methodology for the synthesis of substituted naphthalocyanines starting from an octahalogenated phthalocyanine. The other one, was to synthesize a novel phthalocyanine derivative starting from 3,4-dicyano-1,6-methano[10]annulene, which under cyclotetramerization conditions furnished a compound with absorptions at 720 and 800 nm.

The present research had as an objective to identify the concepts multifunctional-resource-class teachers and school supervisors have of intellectual disability and evaluation, after being submitted to an education course. It also aimed at analyzing how the assessment processes of students showing possible intellectual disability for enrollment in special education programs have been occurring, and subsidize work in a pedagogical evaluation which guarantees each and every student the right to learn in school. Developed in a town in Parana State which adopts the psycho-educational evaluation in the school context, a model constituted of pedagogical assessment aided by psychological opinion with the diagnoses of the disability, its subjects were the multifunctional-resource-class teachers and school supervisors of the public municipal education network, the ones in charge of the pedagogical assessment and the Coordinator of Basic Education of Secretaria da Educação Municipal ( Municipal Board of Education). Supported by critical educational theories and their bases, the methodological forwarding happened under a historic and dialectic perspective, whose approach makes possible the proximity and understanding of social practices which involve the processes studied, in order to more than understand them, to try to transform them. The course offered to the participants in the research was based in the historic-critic pedagogy and the educational meetings were videotaped for data collection. The talks were transcribed and organized in theme axes about: the education course, concepts of evaluation, concepts of intellectual disability and evaluation practices. As a result, it was verified that the participants’ concepts of evaluation validate this tool as a means to indicate ways towards the student’s learning. Nevertheless, the course takers focus more on the skills that must be developed by the students than on the factors external to them, which make this development possible, such as the very pedagogical practice itself. Concerning the concept of intellectual disability, it was noticed a mixture of concepts: some course takers present a speech primarily focused on an organicist view, and others, more focused on the interaction perspective. About the evaluation practice, it was verified that the course takers have knowledge about the necessary proceedings to refer the students to assessment and the norms adopted by the city; some course takers showed resistance to the participation of school professionals in the evaluation process, indicate the segmentation among the teams who act within and outside the school, besides the predominance of the opinions of such teams over the ones of the school pedagogical team. The clinical area professionals’ diagnoses are considered important, however criticism to them can be noticed, especially when their results do not correspond to the expectancy of the school. Based on the pedagogical evaluation performed in the school context, reports on students who had their learning process redefined and stopped being sent for psychological assessment in order to identify a possible disability outstands. It is concluded that the education course offered constituted a space for reflection, which made possible, changes in concepts of intellectual disability and its evaluation processes.

This research is based on the premise that the improvement of bicycle transport conditions could help improve the quality of life in cities, due to the wide range of social, environmental, economic and health benefits associated with this mode. The purpose of the cycling networks addressed in this study is to establish connections between potential points of origin and destination of cyclists, in order to offer the most appropriate routes between the points of interest. For this, the identification and study in the Travel Generating Poles (PGVs) are convenient, since Origin-Destination (O / D) surveys, capable of providing information about travel demands, are rare in the context of Brazilian cities. The prerogative of this study is to identify the implications of opinions and travel behavior of cyclists in the planning of cycling networks in medium-sized cities. Based on the bibliographic review, the main factors that influence the choice of routes by cyclists were identified, as well as some models of bicycle service level evaluation (NSB), in order to provide a solid theoretical discussion, allowing a better understanding of the studied reality. Subsequently, surveys have been carried out with cyclists at Bicycle Travel Generating Poles (application of a questionnaire and registration of routes traveled by cyclists using GPS devices), followed by the diagnosis of the Level of Service for Bicycle of the routes traveled by cyclists and the shortest ways between origins and destinations of cyclists. The implications of cyclists' opinions and travel behavior for cycling planning lie in directing the proposition to direct cycling networks, that minimize the deviation of connections between origins and destinations (PGVs), as well as provide basic infrastructures such as adequate lighting and well-maintained pavement.

It is known that transition metal complexes are compounds with a wide range of applications, due to, for example, its structural versatility and variability of electronic properties. A wide range of these compounds have vital functions in living organisms, being found in enzymes, proteins and cofactors. So, the potentiality of such complexes for the catalytic activity is related to the presence of possible active sites for substrate coordination and the occurrence of the catalyzed reaction. In search for inorganic compounds that act as mimetic models for the enzyme Catechol Oxidase, there were synthesized monometallic zirconium (IV) and zinc (II) complexes. The ligands used were tridentate Schiff base originated by the reaction between diaminomaleonitrile and salicylaldehyde, or 4-substituted salicylaldehyde. Those compounds were characterized through techniques such as solubility tests, melting point tests, molar conductivity measures, vibrational and electronic spectroscopies and 1H nuclear magnetic resonance. The complexes were tested for its functional mimetic activity for the enzyme Catechol Oxidase by conducting the reaction between 3,5-di-tert-butylcatechol and O2, to form 3,5-di-tert-butyl-ortho-quinone. It was found that in 24 h the zinc complex without substituent on the aromatic ring of the ligand has a catalytic behavior, resulting in a conversion 17 % higher than that observed in the test without catalyst. The results for all other complexes suggested inhibitory activity and the tested zirconium complex was the one which the inhibition effect was more pronounced. In the first four hours of reaction it presented conversions of 5 % of the converted in the test without catalyst.

The aim of this work is to apply design of experiment methodologyin the development of a dissolution method during the early phase ofdevelopment of a generic product in pharmaceutical industry. The model drug used during the development was the biphasic release product Zolpidem CR, which contains 12.5 mg of Zolpidem Hemitartrate per tablet. Previous to experimental design, a Failure Mode and Effect Analysis (FMEA)was performed to choose the most important variables.Four variables were considered the most importants to affect product release rate, which wereapparatus, rotation speed, volume and pH of the dissolution media. The variables selected were analysed by the full factorial design with the objective to identify the principal factors. The most critical factors were then used to construct the response surface model in order to model all variables and understand its interaction. The objective at this phase of product development was to reach anin vitro dissolution similar to the one in vivo, therefore all the responses were based on the in vivo absorption rate of the reference product obtained from literature. The mean Zolpidem plasma concentration-time profiles was deconvoluted by Wagner Nelson method and the deconvoluted curve was modeled to Logistic model. The parameters of the equation wereused as reference response. The responses monitored were the percentage dissolved in 0.25, 4.0 h, and the α ,β and R2 parameters of logistic equation. The model reliability and significance of the factors studied was evaluated by the analysis of variance (ANOVA). Two methods were used to determine the best dissolution condition, the first one was the Desirability Function and the second was the response surface sobreposition. The dissolution condition of basket with a rotation speed of 50 rpm and dissolution media of HCl 0,01 M (pH 2,0) with a volume of 500 ml was choosen as the condition that satisfied the desirability criterias stablished at the beginning of the experiment. The design of experiment methodology proved to be a more efficient methodology comparade to the traditional one factor at time (OFAT) method, reducing the number of experiments, number of samples and time to method development. The comprehension of the factors that affect release rate of the product and conclusion showed to be significantly superior to the traditional method.
