It is believed that the use of hormones may be safer and more effective than the non-bioidentical hormones, because binding to receptors in the organism would be similar to the endogenous hormone. Bioidentical estrogens have been used in menopausal women, as an alternative to traditional hormone replacement therapy. Thermal data of these hormones are scarce in literature. Thermal analysis comprises a group of techniques that allows evaluating the physical-chemistry properties of a drug, while the drug is subjected to a controlled temperature programming. The thermal techniques are used in pharmaceutical studies for characterization of drugs, purity determination, polymorphism identification, compatibility and evaluation of stability. This study aims to characterize the bioidentical hormones estradiol and estriol through thermal techniques TG/DTG, DTA, DSC, DSC-photovisual. By the TG curves analysis was possible to calculated kinetic parameters for the samples. The kinetic data showed that there is good correlation in the different models used. For both estradiol and estriol, was found zero order reaction, which enabled the construction of the vapor pressure curves. Data from DTA and DSC curves of melting point and purity are the same of literature, showed relation with DSC-photovisual results. The analysis DTA curves showed the fusion event had the best linearity for both hormones. In the evaluation of possible degradation products, the analysis of the infrared shows no degradation products in the solid state / Horm?nios bioid?nticos s?o compostos que t?m exatamente a mesma estrutura qu?mica e molecular dos horm?nios end?genos humanos. Acredita-se que a utiliza??o desses horm?nios pode ser mais segura e eficaz que os horm?nios n?o-bioid?nticos, pois a liga??o aos receptores no organismo se daria de forma semelhante aos horm?nios end?genos. Estrog?nios bioid?nticos v?m sendo utilizado, em mulheres na menopausa, como uma alternativa ? terapia de reposi??o hormonal tradicional. Dados t?rmicos desses horm?nios s?o escassos na literatura. A an?lise t?rmica ? um conjunto de t?cnicas que possibilita medir as propriedades f?sico-qu?micas de uma subst?ncia em fun??o da temperatura. As t?cnicas t?rmicas v?m sendo utilizadas na ?rea farmac?utica em diversas aplica??es, como na caracteriza??o de f?rmacos, determina??o do grau de pureza, identifica??o de polimorfismo, estudos de estabilidade e compatibilidade. Este trabalho tem como objetivo a caracteriza??o dos horm?nios bioid?nticos estradiol e estriol atrav?s das t?cnicas t?rmicas TG/DTG, DTA, DSC, DSC-fotovisual. A partir da an?lise das curvas TG, foi poss?vel calcular os par?metros cin?ticos para as amostras. Os dados cin?ticos mostraram boa correla??o entre os diferentes modelos empregados. Tanto para o estradiol como para o estriol, foi encontrada ordem zero de rea??o, o que possibilitou a constru??o das curvas de press?o de vapor. Dados das curvas DSC e DTA sobre ponto de fus?o e pureza s?o condizentes com a literatura, sendo poss?vel correlacionar estes resultados com o DSC-fotovisual. As an?lises das curvas DTA mostraram o evento de fus?o como o de melhor linearidade para os dois horm?nios. Na avalia??o dos poss?veis produtos de degrada??o, a an?lise do infravermelho mostra que n?o houve produtos de degrada??o no estado s?lido

This tendentious urbanization were marked for an expressive increase of number of horizontal and vertical closed residences joint ownership concerning at social groups more privileged financial position. Go after, set off, a temporal investigation, based in the forms of appropriation of space in the middle intermediate by action of the several producers agent of capitalist capital. This way, make necessary understand the past of local structure earth, in order that to make possible analyze the beginning of the process. Not enough, appealed the publics institutions as immobile notary s office and secretary municipal for to collect the more important information, and in the field through of application of formulary together the population of ward, in order that of examine the motivation of residential establishment inside. Make this, confirmed that the actual spatial organization of ward of Nova Parnamirim started of two allotments: the Vale do Pitimb? Park and Eucaliptos Park, both divided in several little allotments. Before of begin the ward, allotments reproduced set off from that native has been consigned during the 80, 90 decade s and begin the actual century, resigning a complicated urban structure earth, dynamized by exploration of a promising residential area. Leashed of this, confirmed the installation of logic of segregation and auto-segregation conducted by an immobile market which exclude the poor class and absorb rich class, motivate by perspective of obtaining of urban lace of earth by immobile promoter. However, perceived that the growth this market was promoted by migration of groups of capital, interior of state and others regions of country. Not distant, horizontal and vertical closed residences represent production forms of a new form of residence, corresponding the pattern architectonic as socioeconomics, strengthened by ideal of security, quality of life, necessity of reclusion and of proximity of Natal. Is in the capital which this individual found possibilities of attend satisfactory minimum of yours necessity in relation a consumption of bens and specialized and specifics services. Before this qualitative perceive that the social and spacial differential of Nova Parnamirim was the responsible by soil and habitation valorization of ward, that reinforce the promotion of segregation and of auto-segregation, and consequently, of capitalist reproduction of urban space / O trabalho aqui exposto desejou investigar o papel da evolu??o dos loteamentos fechados, do mercado de terras e das formas de extra??o da renda fundi?ria, no processo de produ??o capitalista do espa?o urbano em Nova Parnamirim, munic?pio de Parnamirim/RN. Essa tendenciosa urbaniza??o foi marcada por um expressivo aumento do n?mero de condom?nios residenciais fechados horizontais e verticais referentes a grupos sociais mais privilegiados financeiramente. Procurou-se, a partir da?, uma investiga??o temporal, baseada nas formas de apropria??o do espa?o mediadas pela a??o dos diversos agentes produtores da cidade capitalista. Nesse sentido, fez-se necess?rio entender a historicidade da estrutura fundi?ria local, para que se pudesse analisar o princ?pio do processo. N?o obstante, recorreu-se a institui??es p?blicas como cart?rios imobili?rios e secretarias municipais para coletar as informa??es mais importantes e, ao campo atrav?s da aplica??o de formul?rios junto ? popula??o do bairro, com intuito de averiguar as motiva??es de estabelecimento residencial no mesmo. Feito isso, confirmou-se que a atual organiza??o espacial do bairro de Nova Parnamirim partiu de dois loteamentos: o Parque Vale do Pitimb? e o Parque dos Eucaliptos, ambos fracionados em v?rios loteamentos menores, nas d?cadas de 80, 90 e 2000, conformando uma intricada estrutura fundi?ria urbana. Atrelado a isso, constatou-se a instala??o de uma l?gica de segrega??o e auto-segrega??o conduzida por um mercado imobili?rio que exclui os insolv?veis e absorve os solv?veis, motivado pela perspectiva de obten??o de rendas fundi?rias urbanas pelos promotores imobili?rios e pela migra??o de grupos da capital, do interior do Estado e de outras regi?es do pa?s. Os condom?nios fechados horizontais e verticais representam formas de produ??o de uma nova forma de moradia, no que diz respeito tanto aos padr?es arquitet?nicos como socioecon?micos, fortalecida pelo ideal de seguran?a, qualidade de vida, pela necessidade da reclus?o e da proximidade de Natal, com ?nfase para o consumo de bens e servi?os especializados e espec?ficos.

In this way, the present study has as objective analyse the expansion of the horizontal closed condominiums on the urban area of Natal. Emphasizing the sociogeographic changes that these ventures engender. For this, we have done a research that was based on quantitative procedures, however, preferring a qualitative approach. So, data were gathered from sources and procedures: the first, we performed a literature search and document on issues related to the relevant issues in libraries, public and privates institutions; The second, in accordance with the procedures, or the production of informations, performed enterview and implemetation of questionnaires with key stakeholders involved with the expansion of horizontal condominiums in Natal. Within this perspective, our research showed that the expansion of demand in the city, the existence of volume of land in areas suitable for the production building, the formation of capital property, the appearance of new points of modern consumption, the actions of the state and the low cost of production of these enterprises, are factors that have been decisive in the expansion of the horizontal condominiums in Natal. Also, we can observe that the process of production of the urban space from the horizontal condominiums comes in providing the redefinition of land use in areas that appear, because they expand into outlying areas of Natal, changes in its structure and its pattern of socio segregation, observing that the condominiums put the diferents social groups living side by side, but not mantaining relationships among them, the emergence of spaces to homogenization, the fragmentation of the urbanization, the privatization of the city and several environmental problems. In short, we believe that the horizontal expansion of condominiums is enabling a number of social changes to Natal city / O processo de urbaniza??o da cidade de Natal vem passando nos ?ltimos anos por altera??es substanciais, principalmente, porque presenciamos a expans?o de uma nova tipologia de moradia, os condom?nios horizontais fechados, que a partir de 1995 passaram a se expandir rapidamente no tecido da cidade. Dessa forma, o presente estudo tem como objetivo analisar a expans?o dos condom?nios horizontais fechados no espa?o urbano de Natal, dando ?nfase ?s transforma??es socioespaciais que esses empreendimentos engendram. Para tanto, fizemos uma pesquisa que teve como base os procedimentos quantitativos, por?m, privilegiando uma abordagem qualitativa. Assim, foram levantados dados a partir de fontes e procedimentos. Na etapa que diz respeito ?s fontes, realizamos uma pesquisa bibliogr?fica e documental sobre temas relacionados ? problem?tica em quest?o em bibliotecas, institui??es p?blicas e privadas; na etapa concernente aos procedimentos, ou a produ??o de informa??es, realizamos entrevistas e aplica??o de question?rios com os principais agentes sociais envolvidos com a expans?o dos condom?nios horizontais em Natal. Dentro desta perspectiva, nossa pesquisa revelou que o alargamento da demanda solv?vel na cidade, a exist?ncia de volume de terras em ?reas adequadas ? produ??o imobili?ria, a forma??o do capital imobili?rio, o surgimento de novos pontos de consumo moderno, a atua??o do Estado e o baixo de custo de produ??o desses empreendimentos, s?o fatores determinantes na expans?o dos condom?nios horizontais em Natal. Al?m disso, verificamos que o processo de produ??o do espa?o urbano a partir dos condom?nios horizontais traz em seu bojo uma s?rie de implica??es socioespaciais para a cidade de Natal, tais como: redefini??o no uso do solo nas ?reas em que surgem, uma vez que se expandem em ?reas perif?ricas de Natal; mudan?as na estrutura urbana e no padr?o de segrega??o socioespacial da cidade, tendo em vista que os condom?nios p?em os diferentes grupos sociais convivendo lado a lado, por?m n?o mantendo rela??es entre si; surgimento de espa?os tendentes homogeneiza??o; fragmenta??o do tecido urbano; privatiza??o da cidade e uma s?rie de impactos ambientais

In addition, differently of what happens for most of numerical techniques, for which the associated simulations computational time tends to increase exponentially with the complexity of the problems, in the Monte Carlo the increase of the computational time tends to be linear. Nevertheless, the Monte Carlo solution is highly computer time consuming for most of the interest problems. The Multispectral Energy Bundle model allows the reduction of the computational time associated to the Monte Carlo solution. The referred model is here analyzed for applications in media constituted for nonparticipating species and water vapor, which is an important emitting species formed during the combustion of hydrocarbon fuels. Aspects related to computer time optimization are investigated the model solutions are compared with benchmark line-by-line solutions

That s why, we take the concept of cognitive domains as equivalent to the structures that are stored in our memory from our sociocultural and corporeal experiences and they are stabilized, respectively, through the frames and schemas. The activation of these conceptual domains, as evidenced by our data, supports the assumption that previous knowledge from our inclusion in specific sociocultural contexts, concurrently with the functioning of our sensory-motor system are essential during the construction activity direction.

Various studies have revealed differences in both distribution and density of this cell group throughout distinct cortical areas in several species. A particular class of interneuron closely related to cortical modulation is revealed by the immunohistochemistry for calcium binding proteins calbindin (CB), calretinina (CR) and parvalbumin (PV). Despite the growing amount of studies focusing on calcium binding proteins, the prefrontal cortex of primates remains relatively little explored, particularly in what concerns a better understanding of the organization of the inhibitory circuitry across its subdivisions. In the present study we characterized the morphology and distribution of neurons rich in calcium-binding proteins in the medial, orbital and dorsolateral areas of the prefrontal cortex of the marmoset (Callithrix jacchus). Using both morphometric and stereological techniques, we found that CR-reactive neurons (mainly double bouquet and bipolar cells) have a more complex dendritic arborization than CB-reactive (bitufted and basket cells) and PV-reactive neurons (chandelier cells). The neuronal densities of CR- and CB-reactive cells are higher in the supragranular layers (II/III) whilst PV-reactive neurons, conversely, are more concentrated in the infragranular layers (V/VI). CR-reactive neurons were the predominant group in the three regions evaluated, being most prevalent in dorsomedial region. Our findings point out to fundamental differences in the inhibitory circuitry of the different areas of the prefrontal cortex in marmoset / Os interneur?nios do c?rtex cerebral s?o caracterizados por suas diferentes propriedades morfol?gicas, fisiol?gicas e bioqu?micas, atuando como moduladores da atividade excitat?ria cortical dos neur?nios piramidais, por exemplo. V?rios estudos revelaram diferen?as na distribui??o e densidade deste grupo celular ao longo de diferentes ?reas corticais em diversas esp?cies. Uma classe particular de interneur?nios intimamente relacionada ? modula??o cortical ? revelada pela imunohistoqu?mica para as prote?nas ligantes de c?lcio calbindina (CB), calretinina (CR) e parvalbumina (PV). Em que pese a quantidade crescente de estudos focando nas prote?nas ligantes de c?lcio, o c?rtex pr?frontal de primatas ainda permanece relativamente pouco explorado, especialmente no que se refere a um melhor entendimento da organiza??o do circuito inibit?rio ao longo de suas subdivis?es. No presente estudo caracterizamos a morfologia e a distribui??o desse grupo neuronal nas regi?es medial, orbital e dorso-lateral do c?rtex pr?-frontal do sagui (Callithrix jacchus). Utilizando par?metros morfom?tricos e t?cnicas estereol?gicas, evidenciamos que os neur?nios reativos a CR (especialmente c?lulas em duplo-buqu? e bipolares) possuem arboriza??o dendr?tica mais complexa quando comparados aos neur?nios reativos a CB (neur?nios de tufos duplos e c?lulas em cesto) e PV (c?lulas em candelabro). A densidade dos neur?nios reativos a CB e CR ? mais elevada nas camadas supragranulares (II/III), enquanto os neur?nios reativos a PV se concentram predominantemente nas camadas infragranulares (V/VI). Os neur?nios reativos a CR foram o grupo predominante nas tr?s regi?es avaliadas, sendo mais prevalente na regi?o dorsolateral.

How is this attraction established? Which signs are characteristic of a good partner? These and many other questions concerning how mate attraction and mate selection work out among humans have been intriguing behavioral scientists. It is well-known that beauty indicates something about a potential mate s health. The odor may indicate a similar assessment, if we can assess how pheromones are integrated into human sexual behavior. However, what is the relation between age preference and body scent evaluation? In order to investigate this question, this study?s objective was identifying evidences which show that olfactory cues might reveal the potential mate s age and that it coincides with the ideal mate s profile. To produce the stimuli, men and women had to wear cotton t-shirts for three nights in order to have their body odor impregnated. After that, opposite-sex individuals evaluated the intensity and attractivity of these odor impregnated tshirts according to two Likert scales (4 points scale for intensity; 7 points scale for attractivity). We found differences between men and women on body scent perception, that indicates a better scent discrimination for women when it concerns the perception of potential mate s age. Another finding was the negative correlation between intensity and attractiveness perception for both sexes. We also verified that mate selection strategies are plural, more than one tactic simultaneously fitting in the same strategy, but all of them are related to differential investment of each sex on their own reproductive success / Por que nos sentimos atra?dos por algumas pessoas e por outras n?o? O que define essa atra??o? Quais os sinais que definem um bom parceiro? Essas e muitas outras perguntas sobre como se d? a atra??o e a sele??o de parceiros na esp?cie humana v?m intrigando os cientistas do comportamento. J? entendemos que a beleza nos indica muito da sa?de de um parceiro em potencial. O odor pode nos indicar um caminho similar se entendermos como os ferom?nios se integram no comportamento sexual humano. Entretanto, como se relaciona a prefer?ncia de idade e a avalia??o do odor corporal? Esse estudo se prop?e a encontrar evid?ncias que mostrem que pistas olfativas podem nos revelar a idade de um parceiro em potencial e que essa idade coincide com o perfil ideal para um parceiro. Para tanto, foram utilizadas camisetas de algod?o que foram impregnadas com o odor corporal de homens e mulheres. Esses odores, posteriormente, foram avaliados por indiv?duos do sexo-oposto quanto a sua intensidade e atratividade em duas escalas (intensidade 4 pontos e atratividade em 7 pontos). Encontramos que homens e mulheres diferem na percep??o de odores corporais, com as mulheres apresentando um melhor discernimento quanto ? avalia??o de cheiro quando se trata de perceber a idade de um parceiro em potencial. Outro achado foi a exist?ncia de uma correla??o negativa entre a percep??o de intensidade e de atratividade, em ambos o sexo. Verificamos ainda que as estrat?gias de sele??o de parceiros s?o plurais, cabendo mais de uma t?tica harmonicamente numa mesma estrat?gia, e que estas est?o relacionadas ao investimento diferencial que cada g?nero faz no seu pr?prio sucesso reprodutivo

Neste estudo, propomos testar se a varia??o ambiental do litoral brasileiro ? suficiente para criar filtros adicionais para as esp?cies da restinga. Localiza??o: Toda a extens?o da costa do Brasil, Am?rica do Sul. M?todos Constru?mos uma base de dados contendo informa??es bin?rias da flora terrestre da restinga presente em 164 localidades ao longo do litoral brasileiro. Para cada uma destas localidades, obtivemos um conjunto de 41 vari?veis ambientais, incluindo vari?veis clim?ticas e ed?ficas. Usamos Modelos de Arqu?tipos de Esp?cies (MAEs) para avaliar a resposta das esp?cies da restinga ? varia??o representada pelas vari?veis abi?ticas. Tamb?m investigamos a exist?ncia de gradientes flor?sticos atrav?s de uma An?lise de Coordenadas Principais (ACoP). Usamos estas duas abordagens estat?sticas para os dados de esp?cies herb?ceas e lenhosas, separadamente. Resultados: Foram formados 4 arqu?tipos de esp?cies herb?ceas em resposta a 10 vari?veis ambientais e 10 arqu?tipos de esp?cies lenhosas em resposta a 6 vari?veis ambientais. Os arqu?tipos de esp?cies herb?ceas responderam aos gradientes ambientais mais fortemente que os arqu?tipos de esp?cies lenhosas, embora, em geral, apenas poucos arqu?tipos mostraram fortes respostas ? varia??o ambiental. Adicionalmente, as comunidades herb?ceas da restinga n?o foram estruturadas por gradientes flor?sticos significativos e as comunidades lenhosas n?o formaram gradientes flor?sticos n?tidos, sugerindo um alto n?vel de estocasticidade na forma??o da estrutura flor?stica da restinga. Principais Conclus?es: A varia??o ambiental do litoral brasileiro parece criar filtros adicionais para as esp?cies herb?ceas e lenhosas da restinga, o que ? mais importante para a distribui??o das esp?cies herb?ceas. A baixa resposta das esp?cies ?s vari?veis ambientais sugere que a varia??o flor?stica da restinga resulta mais da rela??o espacial entre a restinga e os Dom?nios flor?sticos adjacentes. / Aim The plant communities of restinga are shaped by species from Caatinga, Cerrado, Amazon and Atlantic Domains which are able to cope with stressful conditions from the Brazilian coast. We tested whether environmental variation along the Brazilian coast is strong enough to impose additional filters for the restinga species. Location The entire coast of the Brazil, South America. Methods We gathered information about species composition from 164 distinct localities along the Brazilian coast to construct a binary database of restinga flora. For each of these localities, we obtained a set of 41 environmental variables, including climate and edaphic variables. We used Species Archetype Models (SAMs) to evaluate the response of the restinga species to the variation represented by abiotic variables. We also investigated the existence of floristic gradients using a Principal Coordinates Analysis (PCoA). We use these two statistical approaches for data of herbaceous and woody species, separately. Results We found four archetypes of herbaceous species in response to 10 environmental variables, and 10 archetypes of woody species in response to 6 environmental variables. The archetypes of herbaceous responded to environmental gradients more strongly than archetypes of woody species, althout, in general, just few archetypes showed strong responses to environmental variation. Additionally, the herbaceous communities from restinga were not structured by significant floristic gradients and the woody communities did not have clear floristic gradientes, suggesting a high level of stochasticity shapping the floristic structure of restinga. Main conclusions The environmental variation along the Brazilian coast seems to create additional filters for herbaceous and woody species of restinga, which are more important to the distribution of herbaceous species. However the low response of species to the environment suggests that the floristic variation of restinga results over from a spatial relationship between the restinga and the Caatinga, Cerrado, Amazon, Atlantic and Pampa Domains.

Onde a topologia deste espa?o de Baire ? a topologia induzida de uma topologia de Scott para as fun??es parciais (n?o necessariamente comput?veis). Nesta tese constr?i-se uma topologia original no conjunto de ?ndices das fun??es totais comput?veis e demonstra-se que ela n?o ? homeomorfa com o subespa?o do espa?o de Baire que foi mencionado. H? um subconjunto indecid?vel importante no conjunto de fun??es totais comput?veis chamado ?o conjunto de fun??es comput?veis regulares?, que recebe aten??o especial nesta tese. Com a finalidade de fazer um estudo topol?gico deste conjunto constr?i-se todo um aparato te?rico. Ap?s apresentar o estado da arte da teoria dos dom?nios generalizada introduz-se uma generaliza??o original dos dom?nios alg?bricos nomeados como ?quase dom?nios alg?bricos?. Com uma ordem parcial adequada, constr?i-se um quase-dom?nio alg?brico para o conjunto de fun??es comput?veis totais. Por meio da topologia de Scott associada a esse quase-dom?nio alg?brico, obt?m-se uma condi??o necess?ria para as fun??es comput?veis regulares. Fica provado que esta ?ltima topologia n?o ? homeomorfa com o subespa?o previamente mencionado do espa?o de Baire apresentado. Como subproduto, introduz-se uma topologia de Scott para o conjunto de fun??es totais (n?o necessariamente comput?veis). Fica provado que esta ?ltima topologia n?o ? homeomorfa com o espa?o de Baire apresentado. Fica tamb?m provado que as topologias de Scott no conjunto de fun??es totais e no subconjunto de fun??es totais comput?veis t?m o conjunto de fun??es totais com suporte finito como conjunto denso comum. Analogamente, fica provado que a topologia no conjunto ?ndice do conjunto de fun??es totais comput?veis tem como conjunto denso os ?ndices correspondentes a uma enumera??o comput?vel sem repeti??o do conjunto de fun??es totais com suporte infinito. / Topologically the set of total computable functions has been studied only as a subspace of a Baire space. Where the topology of this Baire space is the induced topology of a Scott topology for the partial functions (not necessarily computable). In this thesis a novel topology on the index set of the set of total computable functions is built and proved that it is not homeomorphic to the aforementioned subspace of the presented Baire space. There is an important undecidable subset of the set of total computable functions called the set of regular computable functions that receives particular attention in this thesis. In order to make a topological study of this set a whole theoretical apparatus is constructed. After presenting the state of the art of generalised domain theory, a novel generalisation of algebraic domains coined as algebraic quasidomains is introduced. With a suited partial-order an algebraic quasi-domain is built for the set of total computable functions. Through the Scott topology associated with this algebraic quasi-domain a necessary condition for the regular computable functions is obtained. It is proved that this later topology is not homeomorphic to the previously mentioned subspace of the presented Baire space. As a byproduct a Scott topology for the set of total functions (not necessarily computable) is introduced. It is proved that this later topology is not homeomorphic to the presented Baire space. It is also proved that the Scott topologies in the set of total functions and in the subset of total computable functions have the set of total functions with finite support as a common dense set. Analogously it is proved that the topology in the index set of the set of total computable functions has as a dense set the indexes corresponding to a computable enumeration without repetition of the set of total functions with finite support.

This dynamic produces a spatial organization, territorially scattered of the low density urban tissue, which results in, among other consequences, the increase of the urbanization costs, a fragmented city, loss of cultural identity, related to the use of the city, etc. In this perspective has been observed, from the mid 1970 s, the proliferation of the house condominiums construction, as cause and effect of the contemporary urbanization, identified by the paulista metropolitanization. The factors that can explain this dynamic are related, at least, to: 1) land s value, relatively low if compared to other locations in similar context and near Itatiba; 2) advertising and marketing strategies which produce a urban violence scene, non-existent in cities in the mentioned proportions, and relating living in house condominiums to the idea of security; 3) proximity to great metropolitan centers, which generate commercial, industrial and especially services economic flow; 4) the offer of one of the most modern road systems of the country; and, 5) a scene that is predominantly rural and connected to the expectation of a healthy way of life. The analyzed case also reveals, in great manner, evidences of the support that the city s legislation guarantee to the approval and legalization of this sort of state enterprise. / O foco ? an?lise do processo de forma??o dos condom?nios residenciais fechados no munic?pio de Itatiba, estado de S?o Paulo, explicado por meio do fen?meno da metropoliza??o. Essa din?mica produz uma organiza??o espacial do tecido urbano de baixa densidade e territorialmente dispersa, que resulta, entre outras consequ?ncias, o aumento dos custos de urbaniza??o, uma cidade fragmentada, perda da identidade cultural relacionadas aos h?bitos de uso da cidade, etc. Nesta perspectiva ? que se observou, a partir de meados dos anos 1970, a prolifera??o da constru??o de condom?nios residenciais fechados, como causa e efeito do processo de urbaniza??o contempor?nea, identificado pela metropoliza??o paulista. Os fatores que podem explicar essa din?mica est?o relacionados, pelo menos, ao seguinte: 1) valor da terra, relativamente baixo se comparado a outras localidades em contextos semelhantes e pr?ximos a Itatiba; 2) estrat?gias de propaganda e markenting que produzem um quadro de viol?ncia urbana inexistente na cidade nas propor??es anunciadas e relacionando a moradia em condom?nios fechados a id?ia de seguran?a; 3) proximidade a grandes centros metropolitanos geradores de fluxos econ?micos comerciais, industriais e, especialmente, de servi?os; 4) oferta de um dos mais modernos sistemas vi?rios do pa?s; e, 5) paisagem predominantemente rural atrelada ?s expectativas de um modo de vida saud?vel. O caso analisado tamb?m revela de maneira exemplar evid?ncias do respaldo que a legisla??o municipal garante ? aprova??o e legaliza??o dessa forma de empreendimento imobili?rio.
