A Constituio Federal de 1988 e o Estatuto da Cidade estabelecem o Plano Diretor como instrumento bsico da poltica de ordenamento territorial, tendo como princpio fundamental o cumprimento da funo social da propriedade e do direito cidade. Na perspectiva de adequao s diretrizes e objetivos da poltica urbana estabelecidos em 1988, o municpio de Natal elaborou os Planos Diretores de 1994 e 2007, definindo instrumentos e parmetros de regulao do uso e ocupao do solo possveis de assegurar o cumprimento da funo social da propriedade urbana e de gerar subsdios ao planejamento e gesto da cidade. Apesar de Natal ter sido um dos municpios brasileiros pioneiros na adoo desses princ pios, antecipando e incorporando os instrumentos que em 2001 viriam a ser definidos no Estatuto da Cidade, identifica-se que alguns desses instrumentos e parmetros direcionados regulao do uso e ocupao do solo no tiveram sua aplicao plena, a exemplo do mecanismo de acompanhamento e controle dado pelo Estoque de rea Edificvel e da Densidade, que foi substituda pelo Coeficiente de Aproveitamento no Plano Diretor de 2007. Questionando esse procedimento, busca-se na presente pesquisa investigar de que maneira essa substituio do parmetro densidade pelo coeficiente de aproveitamento influenciou na capacidade da gesto pblica de regular os processos de uso e ocupao do solo, de forma a adequar a sua intensificao ao suporte da infraestrutura instalada. Foram tomadas como referncia terico-conceitual as contribuies sobre a prtica de planejamento urbano no Brasil, nos marcos do iderio da reforma urbana, com destaque para as reflexe s de Flvio Villaa, Orlando Alves Santos Junior e Daniel Todtmann Montandon, Luiz Csar de Q. Ribeiro, Raquel Rolnik, Ermnia Maricato, Laura Machado de Bueno e Renato Cymbalista, Jos Roberto Bassul e Carlos F. Lago Burnett, e, com relao aos parmetros de controle urbanstico, o estudo identifica as diferentes abordagens sobre a densidade urbana e o coeficiente de aproveitamento com base nas reflexes de Claudio Acioly Jr., Forbes Davidson, Juan Luis Mascar, Ricardo Ojima, Marcelo de Souza, Jos Rmon Navarro Vera e Armando Ortuo Padilla, Nestor Goulart Reis, Marta Dora Grostein e Susana Ricardo Alves. Como concluso, discute-se a hiptese formulada, inicialmente, de que a mudana de parmetros verificada colocou limites para o municpio realizar uma gesto adequada do solo urbano e, portanto, de fazer cumprir a funo social da propriedade, considerando a necessidade de adequao entre a intensificao do uso e ocupao do solo e a infraestrutura instalada

Trata de describir las caractersticas clnicas del sndrome de Lennox- Gastaut en los nios del Hospital Vicente Corral Moscoso y ADINEA (Asociacin para el Desarrollo Integral del Nio Excepcional del Azuay) de la ciudad de Cuenca-Ecuador; y determinar la relacin existente entre la frecuencia de crisis epilpticas de un nio con diagnstico de sndrome de Lennox-Gastaut y su grado de retardo mental. Son diagnosticados treinta pacientes de los cules 17 fueron del sexo masculino 56,7y 13 pacientes sexo femenino 43,3. La mayora inician sus crisis antes del ao de edad, se relacionan con un mayor retardo mental y a su vez con mayor frecuencia de crisis. La etiologa ms frecuente es la hipoxis al nacimiento, que est relacionada con la precaria atencin de salud del pas, en la mayora de los casos no es posible determinar su etiologa, pero existe una importante predisposicin familiar. Indican que se debera ampliar los mtodos de diagnstico a fin de precisar mejor la etiologa

Objetivo: Determinar la prevalencia de anemia en escolares de 6 a 12 aos del rea urbana de la ciudad de Cuenca y su relacin con el coeficiente intelectual. Diseo: Se realiz un estudio transversal durante los meses de noviembre y diciembre de 2007 en el rea urbana de la ciudad de Cuenca del austro ecuatoriano. Se eligieron 4 escuelas aleatoriamente hasta completar el tamao muestral de 261 nios. Se recogieron los datos antropomtricos (peso y talla); se determinaron los valores de hemoglobina y se realiz un test psicolgico. Resultados: La prevalencia general de anemia fue de 9,6, y de los escolares afectados el 77,77tenan anemia por dficit de hierro. El parmetro antropomtrico que mostr la mayor asociacin con la presencia de anemia fue la relacin entre la estatura y la edad (OR: 1,35 IC: 1,33 - 9,21). La variable anemia se asoci significativamente al coeficiente intelectual en un 17. El porcentaje de nios con desnutricin crnica fue de 11,9y riesgo de desnutricin del 15,7El tipo de escuela se asoci levemente al coeficiente intelectual (p= 0.03) (OR: 1,87 IC: 1,05 - 3,39). No se encontr ninguna relacin entre la prevalencia de anemia por un lado, y el sexo por el otro. Tampoco existi relacin entre la variable sexo y el coeficiente intelectual. Conclusiones: La anemia en general y la anemia ferropnica en particular, no constituyen un problema de salud pblica en la poblacin estudiada. Los escolares con talla alta tienen menor riesgo de desarrollar anemia. La anemia se asoci significativamente al coeficiente intelectual

The present study provides a methodology that gives a predictive character the computer simulations based on detailed models of the geometry of a porous medium. We using the software FLUENT to investigate the flow of a viscous Newtonian fluid through a random fractal medium which simplifies a two-dimensional disordered porous medium representing a petroleum reservoir. This fractal model is formed by obstacles of various sizes, whose size distribution function follows a power law where exponent is defined as the fractal dimension of fractionation Dff of the model characterizing the process of fragmentation these obstacles. They are randomly disposed in a rectangular channel. The modeling process incorporates modern concepts, scaling laws, to analyze the influence of heterogeneity found in the fields of the porosity and of the permeability in such a way as to characterize the medium in terms of their fractal properties. This procedure allows numerically analyze the measurements of permeability k and the drag coefficient Cd proposed relationships, like power law, for these properties on various modeling schemes. The purpose of this research is to study the variability provided by these heterogeneities where the velocity field and other details of viscous fluid dynamics are obtained by solving numerically the continuity and Navier-Stokes equations at pore level and observe how the fractal dimension of fractionation of the model can affect their hydrodynamic properties. This study were considered two classes of models, models with constant porosity, MPC, and models with varying porosity, MPV. The results have allowed us to find numerical relationship between the permeability, drag coefficient and the fractal dimension of fractionation of the medium. Based on these numerical results we have proposed scaling relations and algebraic expressions involving the relevant parameters of the phenomenon. In this study analytical equations were determined for Dff depending on the geometrical parameters of the models. We also found a relation between the permeability and the drag coefficient which is inversely proportional to one another. As for the difference in behavior it is most striking in the classes of models MPV. That is, the fact that the porosity vary in these models is an additional factor that plays a significant role in flow analysis. Finally, the results proved satisfactory and consistent, which demonstrates the effectiveness of the referred methodology for all applications analyzed in this study.

Un hecho que pasa desapercibido para la mayora de las personas, pero no para aquellas que viven cerca de las riberas de los ros pequeos y quebradas, o para los ingenieros hidrolgicos, es el aumento en la frecuencia y magnitud de las avenidas, especialmente cuando la cuenca de la corriente empieza a sufrir las consecuencias de la deforestacin, para dar campo a la urbanizacin y expansin de la ciudad.Este aumento en la frecuencia de las avenidas por causa de un desequilibrio ecolgico natural o artificial, que a su vez es provocado cuando se elimina parcial o totalmente la cobertura vegetal en la cuenca, es investigado en este trabajo, en un caso, a partir de frmulas matemtica empricas deducidas de pruebas experimentales y en otro caso, utilizando una expresin matemtica definida cuya representacin grfica se asemeje al hidrograma de una avenida, tal y como un sinusoide. De los resultados obtenidos en este trabajo, se infiere que cuando se d una ecuacin que represente la frecuencia probable de las avenidas en una corriente, debera indicarse que tal ecuacin es vlida para las condiciones que se observan en la cuenca al momento que se ha hecho el anlisis, puesto que sin dicha cuenca se experimentar un gran cambio en su cobertura vegetal, la frecuencia de las avenidas variara de manera muy significante, aumentando si hay deforestacin o disminuyendo si se tiene un proceso de reforestacin.

The picturesque aesthetic in the work of Sir John Soane, architect and collector, resonates in the major work of his very personal practice the development of his house museum, now the Soane Museum in Lincolns Inn Fields in London. Soane was actively involved with the debates, practices and proponents of picturesque and classical practices in architecture and landscape and his lectures reveal these influences in the making of The Soane, which was built to contain and present diverse collections of classical and contemporary art and architecture alongside scavenged curiosities. The Soane Museum has been described as a picturesque landscape, where a pictorial style, together with a carefully defined itinerary, has resulted in the apotheosis of the Picturesque interior. Soane also experimented with making mock ruinscapes within gardens, which led him to construct faux architectures alluding to archaeological practices based upon the ruin and the fragment. These ideas framed the making of interior landscapes expressed through spatial juxtapositions of room and corridor furnished with the collected object that characterise The Soane Museum. This paper is a personal journey through the Museum which describes and then reviews aspects of Soanes work in the context of contemporary theories on new museology. It describes the underpinning picturesque practices that Soane employed to exceed the boundaries between interior and exterior landscapes and the collection. It then applies particular picturesque principles drawn from visiting The Soane to a speculative project for a house/landscape museum for the Oratunga historic property in outback South Australia, where the often, normalising effects of conservation practices are reviewed using minimal architectural intervention through a celebration of ruinous states.

The Intention to Notice: the collection, the tour and ordinary landscapes is concerned with how ordinary landscapes and places are enabled and conserved through making itineraries that are framed around the ephemera encountered by chance, and the practices that make possible the endurance of these material traces. Through observing and then examining the material and temporal aspects of a variety of sites/places, the museum and the expanded garden are identified as spaces where the expression of contemporary political, ecological and social attitudes to cultural landscapes can be realised through a curatorial approach to design, to effect minimal intervention. Three notions are proposed to encourage investigation into contemporary cultural landscapes: To traverse slowly to allow space for speculations framed by the topographies and artefacts encountered; to [re]make/[re]write cultural landscapes as discursive landscapes that provoke the intention to notice; and to reveal and conserve the fabric of everyday places. A series of walking, recording and making projects undertaken across a variety of cultural landscapes in remote South Australia, Melbourne, Sydney, London, Los Angeles, Chandigarh, Padova and Istanbul, investigate how communities of practice are facilitated through the invitation to notice and intervene in ordinary landscapes, informed by the theory and practice of postproduction and the reticent auteur. This community of practice approach draws upon chance encounters and it seeks to encourage creative investigation into places. The Intention to Notice is a practice of facilitating that also leads to recording traces and events; large and small, material and immaterial, that encourages both conjecture and archive. Most importantly, there is an open-ended invitation to commit and exchange through design interaction.

This analysis of housing experiences and aspirations in three remote Indigenous settlements in Australia (Mimili, Maningrida and Palm Island) reveals extreme liveability problems directly related to the scale and form of housing provision. Based upon field visits to each of the settlements and extensive interviews with residents and local housing and community officers, the paper analyses two aspects of living in such housing conditions at two spatial scales, the layout of the settlement and the design of individual houses. The failings at both scales are shown to be the fault of a dysfunctional housing system that is only recently been addressed.
