This paper aims at developing a better understanding of what has set up the new role of the medium-size cities in Sao Paulo in their urban network as well as how their forms of expansion have contributed to the continuity of the construction of cities increasingly unequal as regards the occupation of the territory. The addressed settings concern the production of Housing Projects of Social Interest promoted by the housing policy aimed at low-income families and the production of Closed Housing Projects associated with land and real estate interests. These modalities help in the spatialization of socio-territorial segregation and supports the understanding of the logic city center x outskirts. The research on two empirical objects aimed to illustrate how these settings appropriate the peripheral areas of the cities of Sao Carlos and Sao Jose do Rio Preto. In order to strengthen the argument, the application of three analyzing variables guided the reading of the processes that have been reinforced as well as the processes that have been provoked in the intra-urban scale. Although the origin of the phenomena is the result of disputes over the occupation of urban space, the analytical approach indicated the similarities and peculiarities which were found in each city.

Stereoscopy is a form of image reproduction older than photography itself, and unlike it, it rearranges the spatiality of the elements in the screen, allowing observers different points of view. Although stereoscopy being a form of visualization this old, it did not remain obsolete. It has been reinvented nowadays with the help of different reproduction techniques. Stereoscopy expanded to the cinema, and recently for television and videogames. Regarding stereoscopy, this dissertation proposes to address how the tridimensional perspective influences the immersive experience in videogames, leading the virtual space of the game, closer to the interactor, which ultimately creates an intimate relationship between those two agents, giving new meanings to the interaction. Thus, for the development of this research, it was necessary to survey the historical evolution of stereoscopy, videogames and devices that enable immersion through virtual reality, to understand how this evolution happened and which was the motivation that led to this demand. After this historical overview, this research proposes to present what are the features that make the act of playing a video game something so immersive that sensitizes players to try new experiences. At last, we analyze games that use stereoscopy as a feature that enables enhanced immersion in their experiences, in order to understand the strategies that these games use to strengthen the link between the interactor and the fantastic interactive worlds, making a survey of the main characteristics that are aggregated to these games.

Stressful situations are a real or potential threat for psychological or physiological integrity of an individual. The underlying neurobiological substrates involved in these processes were substancially investigated through the use of animal models of stress. In this context, a crescent number of studies have used more naturalistic animal tests, such as the social defeat test. Regarding neurobiological substrates, it is known that the amygdala plays an important role in the modulation of defensive responses. This forebrain structure has several neurotransmitters and receptors with important implications in emotional states. In this context, the neuropeptide Corticotropin Releasing Factor (CRF) and its receptors, CRF1 and CRF2, have been recently investigated as an important modulatory system of defensive reactions to aversive situations. Activation CRF mechanisms in the amygdala has been postulated as a possible neurochemical substrate underlying the emotional disorders, especially anxiety disorders, induced by stress in humans. To study anxiety-related responses induced by stressors in animals, the elevated plus maze (EPM) test has been widely used. While previous studies have emphasized the role of CRF1 receptors in modulation of anxiety in rodents exposed to the EPM, the involvement of CRF2 receptors remains unclear. Few studies, however, have investigated the effects of CRF and CRF1 and CRF2 antagonists injected directly into the amygdala on the defensive responses in mice. In addition, several studies are needed to clarify the complex relationship between CRF neurotransmission of the amygdala in the etiology of anxiety disorders related to previous exposure to stress. This study investigated the role of CRF in the amygdala upon the defense reactions evaluated in the EPM in mice previously exposed to acute social defeat. Therefore, we carried out experiments to (i) characterize the effects of acute social defeat on behavior in the EPM and on the levels of plasma corticosterone; (ii) to investigate the effects of intraamygdala microinjection of CRF, CRF1 and CRF2 antagonists on the behavior of mice in the EPM and (iii) to investigate the effects of intra-amygdala microinjections of CRF1 and CRF2 antagonists on anxiety-related behaviors of mice pre-exposed to acute social defeat. Results showed that the exposure to acute social defeat stress produces anxiogenesis at short and long terms (i.e, assessed 5 min and 10 days after stress exposure), however short-term anxiety response is variable. Stress-short term effects are accompanied by increased plasma corticosterone levels. In addition, while intra-amygdala CRF increases anxiety, local injection of CRF1 (but not CRF2) receptor antagonists produced anxiolytic-like effects, suggesting a tonic role of CRF1 in the modulation of anxiety in mice exposed to the EPM. However, it was not possible to determine what is the role of CRF neurotransmission in the responses displayed by mice pre-exposed to social defeat and submitted to EPM.

This thesis describes and analyzes from economic transaction cost (ETC) theoretical framework, formal agreements between ten citrus growers and a set of five citrus processors between 1978/79 to 2011/12 harvest seasons. The research uses an exploratory multiple-case study methodology, to deepen the historical relationships established, identifying transactional and relational elements involved, besides the maladaptation problems. The main objective is to verify empirically contractual governance form in São Paulo citrus complex, in the view of new institutional economics (NIE) and the contracts economy, deepening problems of contractual incompleteness, ex-ante and ex-post opportunism and external/internal transaction enforcements requirements. The result of this academic work is a relational contract model proposition that should be implemented in the negotiation between citrus processors and growers, a new orange box buy and sell contracts, supported by relational governance principles and arbitrated by an independent third party. This relational contract model could give greater governance stability and cohesion, reducing conflicts and also transaction cost between citrus growers and processors, modifying São Paulo citrus crises and stagnation that persist more than one decade.

In this dissertation we made an analytic study of the Bethe Ansatz equations for the XXZ six vertex model with periodic boundary conditions. We had show that the Bethe Ansatz equations deduced from the algebraic and coordinate Bethe Ansatze are related by a conformal map. This allowed us to reduce the Bethe Ansatz equations to a system of polynomial equations. For the one, two and three magnon sectors, we succeeded in decouple these equations, so that the solutions could be expressed in terms of the roots of some self-inversive polynomials, Pa (z). Through new theorems deduced here about the distribution of the roots of self-inversive polynomials in the complex plane, we did a thorough analysis of the distribution of the Bethe roots for the two-magnon sector. This analysis allowed us to show that the Bethe Ansatz is indeed complete for this sector, except at some critical values of the anisotropy parameter A, in which the polynomials Pa (z) may have multiple roots. Finally, an unexpected connection between the Bethe Ansatz equations and the Salem polynomials was found and a new algorithm for search small Salem numbers was elaborated.

Brazilian agriculture is currently experiencing significant losses due to a recently introduced pest, the Helicoverpa armigera caterpillar. Belonging to the Heliothinae subfamily, it is an extremely polyphagous insect that has intensely attacked various crops of economic importance, including soybeans, cotton, corn, beans, and tomatoes. Scientometrics is the quantitative study of scientific production, allowing the evaluation of trends and contributions to research activities carried out by researchers, institutions, or countries in different areas of knowledge. Therefore, the objective of this study was to provide an overview of scientific research on H. armigera in Brazil based on bibliometric indicators. To achieve this, a survey of indexed scientific publications present in the SCOPUS® and Google Scholar® databases was carried out. Between 2005 and 2015, approximately 1,860 documents related to H. armigera were published worldwide. As the pest recently emerged in Brazil, only 22 publications were authored by Brazilian authors in the same period. Therefore, it is observed that the incidence of the pest in Brazil was the main motivation for starting research on the caterpillar in the country, whose management and control are urgently needed.

There are several issues related to the pedagogical use of technologies for the construction of knowledge in the current Brazilian education system. Some pass through large and complex issues, such as the transmission of trend change instruction conducted through blackboard and chalk for a reality involving the use of digital technologies as mediators of this process. In this scenario, the future teacher lacks experience in their formative process, the pedagogical use of technology to be able to incorporate them into their lessons. There are several challenges to this incorporation into the teaching-learning process, since simple computerization of school environment does not guarantee the desired benefits. This study assumes that the pedagogical use of Information and Communication Technologies (ICT) contributes enhancing, facilitating and encouraging the teaching of Mathematics and should be part of initial and continuing teacher training. So this research has the main objective to analyze, from the point of view of the participants in a formative experience, contributions and limits the insertion of the pedagogical use of technology in teacher training so that they can reflect on and use them as a teaching tool in Basic Education in their future professional activities. The theoretical framework for this teacher training focuses on the use of technology in the initial training of teachers of Mathematics and the pedagogical use of ICT. More specifically, it assumes the Lee Shulman knowledge bases and the TPACK framework (Technological Pedagogical Content Knowledge and Technological Knowledge and Pedagogical Content) Koehler and Mishra. Data were produced by 12 undergraduate students who attended a formative experience over the past year students for a Degree in Mathematics. In this experience they had the opportunity to select digital tools and teach specific classes in detail planned for the computer lab. In a later stage, a couple of interns pedagogically used GeoGebra software for teaching quadratic functions for two 1st year of high school classes. Data were obtained through the application of a pool to characterize the subjects and daily researcher and diaries of the participants followed for the practical classes were prepared, as well as interviews from semi-structured pool. The qualitative analysis was organized in a way that links aspects of learning and difficulties that participants had regarding the selection of technologies and their use in simulated classes or basic education, in the computer lab during the supervised training. The results show learnings, indicate potential and limits on the use of technologies and also emphasize the need for experience of undergraduate students in the pedagogical use of ICT so that they feel at ease in using them pedagogically throughout their careers.

In the agri-chain of cassava starch in Brazil, the supply of firms is through different governance structures. These structures range from the purchase via the spot market - without any contractual control over the production - to the hierarchy or vertical integration, structure in which the company is growing in own areas, with full control over the production. Between these two extremes were also identified other governance structures, which are called Hybrid arrangements that can approach the spot market or hierarchy. This essay aimed to identify the factors that influence the decisions of the paranaenses starch factories on the governance structures in buying - cassava supply in the state of Paraná. The specific objectives are: a) show if there is specifics that support the necessity to search for a particular organizational arrangement to the detriment of business through the spot market in the state of Paraná; b) analyze the factors that justify the choices of cassava starch factories for plural or singular forms in the state of Paraná; c) comparing the efficiency of the use or the combination of governance mechanisms in cassava starch factories in Paraná State, considering idleness as an index for the year 2014. The entire analysis of this essay is based on the theoretical assumptions of the New Institutional Economics (NIE), especially in the Transaction Cost Economics (TCE). In this essay the explanatory method was the most appropriate, once for this it sought to identify the determining factors for the occurrence of the phenomena observed: i) coexistence of plural forms of governance to coordinate the purchase of cassava by starch factories in Brazil and in the state of Paraná. This research method more approach the scientific knowledge to the real world as it explains the reason and why the facts. In the case of cassava, the characteristics of transactions - temporal and locational characteristics, as well as uncertainty and frequency – were not relevant for the choice of governance structures, on the contrary to what literature indicates. Even considering these characteristics, in Brazil and in the state of Paraná was prevailing the coordination by the spot market. The results also indicated the existence of a plurality of transactions in many levels - with different agents, and similar agents in a single transaction - since the combination of different governance structures can reduce transaction costs and even increase the efficiency of industry here measured by the reduction of industrial idleness.

For any action in fauna’s conservation it is necessary to have the previous knowledge of the species in order to adopt the best intervention strategies and to optimize the process. This way, even though the Southern Brown Howler monkey is considered vulnerable to extinction in Sao Paulo State, by the Environment Ministry, few studies on these animals have been conducted at the Fontes do Ipiranga State Park - PEFI, Atlantic Forest urban fragment in the city of Sao Paulo. Therefore, this study is aimed to get basic information about the ecology of the two groups that inhabit the region, as home range, activity pattern and diet, create data in the role they play in the maintenance and regeneration of the forest, as the seed dispersers and to analyze the effects on germination in seeds that passes through their digestive tract. The groups were followed in the period of November 2013 to October 2014, the group in the Zoological Park Foundation of São Paulo (area 1), with the final number of five individuals, and the group in the Botanical Garden of São Paulo (area 2), with final composition of nine individuals, both located in the protected area Fontes do Ipiranga State Park - PEFI. The areas belong to different zoning in the management plan of the protected area, and have different degrees of conservation of its forest. Each group was monitored monthly for three full days. Diet items were recorded by the ad libitum method and subsequently identified, totaling 55 species. Syagrus romanzoffiana highlighted by the large participation in the diet of both groups. The seed germination tests comparing a control group (seeds that have not passed through the digestive tract) with samples taken from animal feces showed a significant positive effect on Ficus luschnathiana and Cecropia spp. seeds. The home range was determined by the method of the Minimum Convex Polygons with points being marked in the GPS every half hour, and found home range of 3.5 ha and 5.6 ha for the area’s groups 1 and 2, respectively. The activity pattern was made by the scan sampling method, with scanning every ten minutes and resulted in the usual pattern described for the species: high percentages of time spent resting and low social interaction.

The present research is guided in discourse analysis "about" and "the" practice of security officers at "Cracolândia" (or Crackland) - located in the central region of São Paulo. The main purpose is to identify the differentiation between users and drug dealers by the officers. The empirical view focuses the Municipal Program to Combat Crack and Other Drugs, entitled "Open Arms", which foresees the intersectorality between the work of Social Welfare, Health and Public Safety in the "fight" to crack. I discuss my object from the speeches of security officers, social workers, health workers and crack users on how policing will be in the region as well as on how it is performed in practice. Documental and field research was performed with different agents that act on the management and use of crack users in the region of "Cracolândia". From the field data, it was possible to note the production of a criminal selectivity in how to operationalize the distinction between users and dealers, question to which I would like to give attention. Thus, I try to fill a gap in the studies of public policies to combat the drug in relation to the apparatus of control exercised by state agents of public security in the region of "Cracolândia".

Continuous flow technology of cycloheptanic compounds derived from (R)-(–)-carvone and the C23-C31 fragment used in the total synthesis of spirangien A methyl ester and spirodienal A polyketides” In the first part of this thesis is described the improvement and development of two synthetic routes to the cycloheptenone 73, in the deca-gram scale, from the monoterpene (R)-(–)-carvone (58). Were developed reactions in the continuous flow mode to accelerate and increase the scale production of 73, and thus avoiding chemical logistics issues. Sharing the principle of the diversity oriented synthesis and taking advantage from the cycloheptanic chiron flexibility, were developed α-carbonyl alkylations followed by catalysis with transition metal, to get, in a fast way, structurally diverse compounds such as spiro 74, guaiane type 75, xathane 76 and the tris-ketal compound 78. The second part of this thesis encompasses some results of our collaboration with Prof. Steven V. Ley CBE FRS and deals with the synthesis acceleration of the fragment 145 through the usage of continuous flow processes. The compound 145 is an advanced synthetic intermediate for the spirangien A (79), spirangien A methyl ester (80) and spirodienal A (81) syntheses, which are on matter at the Prof. Ley`s group. xxiii

The aim of this study is to analyze how professionalism, difference, gender and generation in the journalism career are articulated, from the exam of the journalists’ discourses in the city of São Paulo. We use up the concept of professionalism and the Sociology of the Professions theoretical reference, based on the contributions of Eliot Freidson and Julia Evetts to understand the values of journalism, the representations around what it would be the journalist’s function, the meaning of the changes in the profession, with the emergency of a new journalist’s profile, the relations of the profession with the learning at the universities and at the editorial rooms, the historical changes according to the orientation of the journal and the professional, and their specificities with reference to the process of professionalization of the journalism in Brazil. Our aim is to comprehend how female journalists are represented in different discourses of difference. For this, our approach is set on the Avtar Brah’s theoretical assumptions, highlighting the concept of difference as an analytical category and its several meanings. We have also based our analysis on other cultural studies agents that discuss about the decentralization of the subject and its identity, as the internal diversity that characterizes gender. Fifteen journalists were interviewed, women and men, who live and work in the city of São Paulo, of different generations who act in different types of media and with different types of hire in their relations of work. The selection of the interviewed women searched, contemplate single women professionals, married, with or without children, with different time of work, that represent the time dedicated to the personal and professional lives, corresponding to the impact of personal life in the construction of the career and to the possibilities to balance between these two dimensions in the social life.

The Brazilian industry has become in recent decades, which created an intense debate about a possible process of deindustrialization faced by the Brazilian economy. Some authors believe that the country has faced a process of deindustrialization, while others argue that this is just a period of adjustment faced by the economy, which does not characterize this fact. The fall of the Manufacturing Industry's participation in the Gross Domestic Product of the country, coupled with the increase in exports of commodities by Brazil are among the main factors that lead to believe that the country has lost links in the production chain and specializing in goods with little degree of differentiation. In this context, this paper aims to analyze the main data of the Brazilian industry to identify the process of deindustrialization pointed in Brazil. We wanted to understand what the main lines of argument in the debate on the subject, and understand how they behaved the main economic aggregates of the country and other economies in the world, producing a structural analysis on the subject.

The inhibition of the acetylcholinesterase (AChE) might be an excellent therapy in controlling Alzheimer’s disease as stated by the cholinergic hypothesis. In this context, the inhibitors of AChE, are of medical and commercial paramount interest as therapeutics for Alzheimer’s disease and as pesticides. However, the conformational changes in inhibitors with AChE complex facilitate the rational design of some novel inhibitors with increased potency and specificity. Therefore, solution state NMR is a novel approach that seems to fulfil almost all conditions necessary to investigate the AChE-inhibitor complex. In this perspective, a combined strategy of STD, Tr-NOESY, DOSY, and docking simulations were applied to compare the bindings of four synthetic coumarin derivatives to tacrine for their binding potentials. Intriguingly, one of them (compound 1) was found to have not only the stronger affinity than the control but could bind with three sites. Furthermore, a competition of three inhibitors (gallic acid, 4- methylumbelliferone, and scopoletin) was performed by taking help of the STD NMR experiments. Interestingly, none of them was competing for the some particular binding site. Nevertheless, in titration studies gallic acid was found best based on dissociation constant values. Moreover, an ethyl acetate fraction and its water suspension of the Terminalia Chebula RETZ, fruit extract was studied. Three compounds (4-hydroxycinnamic acid, Ethyl-4-hydroxycinnamate and lupeol) were seen to involve in interaction that were later recognized by 2D NMR and ESI mass techniques. Moreover, for the first time in the Federal University of São Carlos, these NMR methods for the determination of the bound conformation of any inhibitors towards AChE using NMR spectroscopy have been applied.

The objective of this thesis is to analyze the Integrated Education, generic name of Professional and Technical Education in middle level combined with a secondary school in integrated mode, under the Law of Directives and Bases of National Education (LDB 9.394/1996) updated through Decree 5.154/2004. We sought to understand what is the integrated education: definition, characteristics, social and political purposes, theoretical-methodological referential and pedagogic-didactic fundamentals. The methodological proceedings was marked: on one hand, by theoretical analysis of the education and of the socialist pedagogy in the thought of Karl Marx, Vladimir Lenin, Nadezhda Krupskaya, Anatoli Lunacharsky and Antonio Gramsci, specifically on the concepts of technology education, polytechnic education and unitary school. On the other by a theoretical and documentary analysis of the legislation, other official documents and literature on the national education and the recent reforms of education, secondary school and integrated education. The study concluded that in the meanders of the integrated education this underlying a broader process of expanding the spirit of professionalization to practically all the Brazilian education system, especially for secondary school. The reform of secondary school, it happened in parallel and conditioned a professionalizing reform.

The replacement of chemical products by renewable raw materials is an important factor for the emission control of CO2. Consequently, there is a great commercial interest in the conversion of ethanol into 1,3-butadiene. The 1,3-butadiene compound is used in the production of a variety of synthetic rubbers and one important example is butadiene-styrene rubber (SBR), which is used in the production of car tires. This work studied the modification of the acid-base properties of MgO/SiO2 bifunctional catalysts and the understanding of different methodologies used in the preparation of these materials for the conversion reaction of ethanol into 1,3-butadiene. MgO/SiO2 catalysts of varying amounts of magnesia/silica were prepared by four different methods: i) precipitation followed by the mixing of the oxides in a ball mill, ii) precipitation of MgO followed by its mixing with aerosil silica in a ball mill, iii) precipitation of MgO followed by the mechanical mixing of the oxides and iv) sol-gel. The catalysts were characterized by X-ray diffraction, CO2 Temperature Programmed Desorption, Scanning Electron Microscopy and Specific Surface Area. Catalytic tests showed that the highest selectivities for 1,3 -butadiene were observed for the (MgO/SiO2) coprecipitation method and oxides mixed in a ball mill. The TPD-CO2 results demonstrate the formation of basic sites with the addition of SiO2 to MgO and the density of basic sites presents a great variation in the ratio MgO: SiO2. The catalyst MgO/SiO2 (5:1) was the most active and selective for 1,3-butadiene. The addition of CaO or SrO these catalysts have not resulted in increased selectivity for the formation of butadiene, but observed an increase in the acid properties, possibly due to non-inclusion of these oxides in MgO lattice and later the formation of basic sites of the type MgO-Mg-O-Si.

Bees are social insects of fundamental importance to the environment, because they are responsible for pollinating more than 70% of existing agricultural crops in the world. Brazil is the country with the highest number of described species, with representatives of most families. Among representatives of the Apidae family, is the Melipona scutellaris specie, commonly known as "uruçu" or "uruçu do Nordeste”, it is easy to handling and very well adapted to the climate of the state of São Paulo. However, due to the intensive use of pesticides, native bees are suffering the consequences, because, although they are not the target of insecticides, are highly vulnerable to contamination. Among the insecticides developed in the 90s, the neonicotinoids and fipronil have been identified as the main substances involved in collapse, and were suspended in 2013 in the European Union for two years for best evaluation. These insecticides are often used simultaneously, so bees can be contaminated with both molecules. Due to this fact, the aim of this study was determine the median lethal time (LT50) of fipronil and imidacloprid insecticides separately and synergistically on forage bees of M. scutellaris. For this, was obtained only the LD50 and LC50 of imidacloprid, according to the rules of the OECD, because values of fipronil were established by Lourenço et al. (2012a, 2012b). The LD50 of imidacloprid obtained was 2.41 ng a.i. / bee (24 hours) and 1.29 ng a.i./ bee (48 hours). The LC50 value found was 2.01 ng a.i./μL diet (24 hours) and 0.81 ng a.i./μL diet (48 hours). These data indicate that M. scutellaris specie is more sensitive to the insecticide imidacloprid that A. mellifera africanized. From these values, was obtained the LT50 based on topical and oral contamination of fipronil and imidacloprid insecticides and also these substances acting together. The results showed that fipronil has LT50 greater than imidacloprid. When acted in combination to LT50 presented intermediate values between the LT50 fipronil and imidacloprid, isolated. Then, according to the values obtained, there was not synergy, but a decrease in the toxicity of imidacloprid.

This work presents the development and implementation of a didactic sequence in order to motivate and teach school students quadratic functions. To do this, we built a cannon made of tiner cans and prepared a serie of activities that have been subdivided into three phases: construction, competition and activities with the use of the software GeoGebra. The work done with students in these aroused a greater interest in the matter and was extremely valuable because students did not forget the acquired learning.

Angiotensin converting enzyme 1 (ACE1) is a dipeptidyl carboxypeptidase that converts angiotensin I (decapeptide) to a vasoconstrictor octapeptide angiotensin II. Thus, ACE presents an important role in blood pressure regulation. There are many synthetic commercially available ACE inhibitors such as captopril, lisinopril and enalapril. Due to their side effects, naturally occurring inhibitors have been prospected. In order to endorse this research field we have developed a new tool for ACE ligand screening. To this end, ACE was extracted from bovine lung, purified and chemically immobilized in modified ferrite magnetic beads (ACEMBs). The ACE-MBs have shown a Michaelian kinetic behavior towards hippurylhistidyl- leucine (HHL) and was also able to catalyze the conversion of angiotensin I to angiotensin II. Moreover, as proof of concept, the ACE-MBs was inhibited by lisinopril with an IC50 of 10 nM. At the fishing assay, ACE-MBs were able not only to fish out the reference inhibitor, but also three peptides from a pool of tryptic digested BSA. ACE-MBs emerge as new straightforward tool for ACE kinetics determination, inhibition and binder screening.
