L étude se fonde sur la recherche du processus inhérent à la conception du projet par le biais de l approche architecturologique proposée par Philippe Boudon et al (2000) ; un modèle théorique qui sert de fondement à la construction d une connaissance de l architecture au moyen d une étude de la nature des opérations mentales de chaque architecte lorsqu il organise son travail de conception. La modélisation de l architecturologie concentre son étude sur le travail qui a lieu avant même la confection matérielle du projet (représentation graphique finale). De cette façon, douze projets furent analysés d architecture résidencielle unifamiliale; conçus récemment par six architectes « potiguares » pour Natal et sa région périphérique. Les résultats mettent en évidence un ensemble de modèles substrats (comme point de départ) et téléologiques (comme point d arrivée) adoptés par les auteurs au cours de la conception de leurs projets. Ces modèles, de façon générale, sont liés aux pertinences socio-culturelles (conventions, formes traditionnelles ou coutumes) du contexte pour lesquels ils sont conçus (lotissements privés de co-propriété des classes moyennes et moyennes-supérieures) et en même temps, ils sont le fruit de croyances, d idéologies et d expériences antérieures propres à l espace de la conception de chaque architecte

The recent tendency to utilize parking lots for other purposes has demonstrated that more time has been spent by visitors, mainly in great cities. Therefore, this paper investigates the thermal comfort and the air quality indoors in areas specifically used as parking lots by analyzing the direct relation between such environments and vehicular pollution. The thermal comfort and the quality of air indoors in parking lots with different architectonic typology (ground-floor and underground) are also studied, aiming to contribute to the proposition of suitable new areas designated to human usage. Field research was done, in two distinct periods within different weather conditions (January and July) in, two naturally cooled, parking lots located in Natal - RN. The internal environment agents were measured by using tools for air temperature, humidity, speed and direction; interviews with employees and visitors and chemical analysis through appropriate tools to analyze specific material, carbon monoxide and ozone. The results showed that chemical agents densely concentrate mostly in the closed parking space, aggravated by weather conditions, which dissatisfied the visitors. Still, it was shown that architectonic typology, alongside topographical aspects compromise internal environmental conditions, which increases the retention of pollution, leading to dissatisfactory thermal comfort levels and becoming less suitable for usage by visitors considering air and thermal comfort aspects. Consequently, they are not suitable for human stay due to the poor quality of the indoor air

As an effect of the growing interdependence in international relations, regional integration was conceived to face globalization, with a remarkable influence in politics and law, since the first steps of the European experience. In Latin America, regional integration ideas have blossomed in the 60 s. Among its experiences, MERCOSUL is the one with the most advanced objectives. However, MERCOSUL has not managed to achieve the objectives planned nor moved forward the integration process. Differently of what happened in Europe, in MERCOSUL the common market projected is concluded. It faced many disappointments throughout its brief history. As it matters to law, those were caused by the absence of supranationality, a mechanism that would allow MERCOSUL s decisions to be directly binding in the States with no need of bureaucratic proceedings to incorporate them to national legal systems. Among Latin American States, Brazil is probably the most resistant to integration process, due to Federal Constitution 1988 rigidity and legal professionals conservadorism towards opening legal system to international law. In Brazil hermeneutical standards are always based on national sovereignty and international law is referred as less important. The problems become more visible relating to taxation, a subject that plays an enormous role in integration process for its economic impact, demanding the execution of tax harmonization policies compatible to the integration levels aspired. However, because of the large number of tax rules in the Federal Constitution, structural changes initiatives face difficulties in order to be implemented. Actually, after two Constitutional Reforms on taxation, Brazil has not yet succeeded on promoting the necessary adaptations to regional integration. The research has confirmed the hypothesis that supranationality has indispensably to be adopted if Brazil really desires to move forward the integration process. But it has also been demonstrated that there are hermeneutical paths suitable to the constitutional profile which allow the adoption of supranationality, through the revision of the sovereignty traditional concept

This study received the title THE JUVENILE EMPLOYMENT IN THE THRESHOLD OF THE XXI CENTURY: study starting from RAIS and of the programs of youths' insert in the labor market of Natal/RN . It presents as main objective to investigate, starting from the officials data of the Ministério do trabalho e emprego - MTE and of the federal and state government programs, the evolution of the formal employment for youths and the difficulties that leads the success of the returned initiatives the youths' insert in the formal market of work in Brazil and in Rio Grande do Norte, in the period from 2000 to 2004. To accomplish the research, it prioritizes the study of the evolution of the formal employment starting from the data of the MTE as form of diagnosing the formal market of the juvenile work. Search a descriptive way to identify the first results of the programs Primeiro Emprego- PPE (federal) and Primeira Chance - PPC (state), to interpret and to identify the existent gaps among the proposal initial of those programs and the first results obtained in the city of Natal. The research has character no-probability and it applies closed questionnaires for youths assisted by the programs. Were interviewed the local representatives of PPE and PPC, besides representatives of the organized civil society all through open structured interview, covering a total of 103 interviews. The results demonstrated that while PPC (state) obtained success inserting youngs, the PPE (federal) just got to insert 1,5% of the amount subsidized by the state program in Natal. That situation demonstrates a clear preference of the companies for PPC (state), in detriment of the federal program

Studies with Stegasta bosquella in peanut crop are little explored by researchers, mainly by the need of obtaining, in the field, a large quantity of closed leaflets. Therefore, it was sought a way of rearing in a natural diet that facilitates the attainment of the insect. The research was developed at the Laboratorio de Resistencia de Plantas a Insetos (FCAV/Jaboticabal) (T: 25 +/- 2 degrees C, RH 60 +/- 10% and photophase: 12 hours) (Runner IAC 886). The rearing stock of was carried out by collecting caterpillars from the field and keeping them in flat bottom glass tubes until adult emergence and test performance. Caterpillars were individualized in Petri dish plates, lined with moistened filter paper, which contained closed and early opened leaflets, but closed with paper clips (imitating the closed leaflet). A randomized design with two treatments and 36 repetitions was used. After the pupae formation, they were separated into five couples and the adults were kept in transparent plastic cages containing a peanut stem with leaves for oviposition, and fed with a 10% honey solution. The duration and viability of the larval and pupal periods, male and female longevity with and without food, and fertility were evaluated. The two forms of larvae rearing (closed leaflet and leaflet closed with clips) did not influence on any of the studied parameters. Therefore, the rearing of S. bosquella becomes feasible in natural diet, which means there is no need to use the enclosed leaflets for this purpose, and implies the easiness for rearing.

As características dos frutos coletados e o sistema de colheita utilizado dependem da espécie que se está estudando. Esses parâmetros devem ser bem estabelecidos para permitir a obtenção de sementes com máxima germinação e vigor. Com o objetivo de determinar as características dos frutos e o sistema de colheita mais favorável à qualidade fisiológica de sementes de Jacaranda cuspidifolia Mart., por dois anos consecutivos foram colhidos frutos na árvore (verdes fechados, marrons fechados e marrons abertos) e frutos marrons no chão. As sementes foram extraídas, limpas e avaliadas quanto ao teor de água, germinação e vigor (primeira contagem do teste de germinação, comprimento da parte aérea e da radícula das plântulas e porcentagem de emergência). Para a obtenção de sementes de jacarandá com melhor qualidade fisiológica, os frutos devem ser colhidos na árvore marrons, abertos ou fechados e com teor de água inferior a 24,4%.

Três estudos foram conduzidos no Núcleo de Pesquisas Avançadas em Matologia (NUPAM) pertencente à UNESP/FCA - campus de Botucatu-SP, com o objetivo de avaliar a estabilidade dos corantes Azul Brilhante FDC-1 e Amarelo Tartrasina FDC-5 quanto a diferentes períodos de exposição à luz solar e contato com folhas de Eichhornia crassipes. No primeiro estudo, soluções de 0,3125, 0,625, 1,25, 2,5, 5, 10 e 20 ppm dos corantes Azul Brilhante FDC-1 e Amarelo Tartrasina FDC-5 foram acondicionadas em tubos de quartzo hermeticamente fechados e submetidos a 0, 0,5, 1, 2, 4, 6 e 10 horas de exposição à luz solar e ao escuro. Ao final de cada período, amostras de 10 mL foram retiradas dos tubos e analisadas. No segundo estudo, os tratamentos foram dispostos no esquema fatorial 2x7: duas condições luminosas (escuro e pleno sol) e sete períodos de exposição (0, 0,5, 1, 2, 4, 6 e 10 horas), com seis repetições. Com o auxílio de micropipeta, oito gotas de 5 µL das soluções Azul Brilhante e Amarelo Tartrasina a 4.000 ppm foram depositadas em placas de Petri de vidro. Após o término dos períodos de exposição, as placas foram lavadas com 50 mL de água destilada, com o objetivo de extrair o corante depositado sobre elas. No terceiro estudo, adotaram-se os mesmos tratamentos do segundo experimento, com quatro repetições, porém as soluções foram depositadas sobre as folhas de plantas de Eichhornia crassipes. Foram adotados também os mesmos procedimentos de extração dos corantes após o término dos períodos de exposição. As soluções finais obtidas nos três estudos foram submetidas à leitura óptica de absorbância em espectrofotômetro UV-visível nos comprimentos de onda de 630 e 427 nm, para os corantes Azul Brilhante FDC-1 e Amarelo Tartrasina FDC-5, respectivamente. As várias concentrações das soluções de ambos os corantes não sofreram degradação pela luz solar quando submetidas aos vários períodos de incidência luminosa nos tubos de quartzo (ambiente fechado), visto que as curvas de recuperação apresentaram equações semelhantes àquelas concentrações que foram mantidas no escuro. A mesma estabilidade também foi observada quando os corantes foram submetidos à luz solar em ambiente aberto, ou seja, nas placas de Petri. O corante Amarelo Tartrasina também se apresentou muito estável quando depositado sobre as folhas de E. crassipes, independentemente da exposição ou não à luz solar. Para o corante Azul Brilhante, ocorreram significativas perdas de 7,8 e 18,6% quando esteve depositado na superfície da folha de aguapé pelo período de 10 horas sob condições de escuro e plena luz solar, respectivamente.

A Neuropatia diabética periférica (NDP) cursa com redução somatossensitiva que pode levar a alterações no controle postural. O objetivo do estudo foi avaliar o controle postural na postura ereta, em diferentes condições, e o equilíbrio funcional em indivíduos com NDP, correlacionar os resultados obtidos na avaliação do controle postural com os valores do teste do equilíbrio funcional e comparar os resultados obtidos no grupo neuropata com o grupo controle, verificando as possíveis diferenças entre as condições de avaliação em ambos os grupos. Participaram do estudo 13 mulheres com NDP (GN) e 17 mulheres não diabéticas (GC). A avaliação do controle postural foi realizada por cinemetria nas condições: olhos abertos (OA), olhos fechados (OF) e semi tandem (ST). Após processamento no MATLAB, foram geradas as variáveis: amplitude média de oscilação (AMO) na direção ântero-posterior (AP) e médio-lateral (ML); e velocidade média de oscilação (VMO) na direção AP e ML. O equilíbrio funcional foi avaliado pelo Timed Up and Go Test. Houve diferença significante entre os grupos (p<0,005) na AMO-AP OA e OF, AMO-ML of e ST e VMO-ML ST. Houve diferença entre as condições OA e ST (p<0,005) e of e ST (p<0,005) para as variáveis AMO-ML e VMO-ML, com maior prejuízo para o GN, que também apresentou um menor equilíbrio funcional (p=0,001). A instabilidade ML foi correlacionada positivamente com o desequilíbrio funcional. Os resultados nos mostram uma alteração no sistema de controle postural na NDP, o que pode levar estes indivíduos a um maior risco a quedas e prejuízos funcionais.

This research has the goal to analyze the urban setting of the Planalto neighborhood, in Natal /RN, seeking to unravel the processes, agents and contradictions associated with the production of the space. The choice of neighborhood is justified by the observation that changes in its urban setting have been growing in speedy way. We highlight the performance of the housing market, in partnership with the state, and the construction of condominiums and buildings closed by the housing program Minha Casa, Minha Vida. This has favored the reproduction of a new " urban reality in the neighborhood, setting an urban standard that differs from the original morphology, seen as peripheral within the urban dynamics of the city. The research is a qualitative study, through documents, interviews with stakeholders, and photographic documentation. In this perspective , we seek to understand the current phase (2000s) the production of space in the neighborhood process through the development of the housing market , as an extension of the urban development in central zone of Natal/RN, analyzing the performance of agents and their producers the "new " uses redefining the "old ". Thus, it can be seen that there is in the neighborhood, urban reality in a pluralistic constitution, from the existence of different social classes inhabiting the same space. On this way, the city is produced from the appropriation of space by different social classes, although due to the economic condition of each of them
