The search for a sustainable urban mobility, has recast the public policy of transport and movement for all, in order to contribute to the welfare economic, social and environmental. Within this context, has as its main objective review here in the city of Natal in the state of Rio Grande Norte, the deployment of the new road infrastructure of the transport corridor of Bernardo Vieira Avenue and checking at least with regard to urban areas and environmental chosen here, as will indicators to assess sustainable urban mobility, that the theory has been well constructed, but in practice little way to apply the proposed guidelines for sustainability. To achieve this result, is initially a literature review with the principal investigators of the matter, since the concepts of indicators of sustainable urban mobility. And a second time, participating in to the case study, using the methodology of environmental awareness, through analysis photographs, notes and testimony in the study area ace to reach conclusions

This dissertation is an attempt to understand how families with an income of up to three minimum wages and living in different Areas of Demographic Expansion (AEDs) of Natal municipality specifically in the districts of Igapó and Salinas (North Administrative Zone of the city), Ponta Negra (South Administrative Zone), Santos Reis, Praia do Meio, Areia Preta and Mãe Luíza (East Administrative Zone) and Felipe Camarão (West Administrative Zone) solve their problems of urban mobility. It is, therefore, a reflection upon the mobility needs of poor urban households as expressed in terms of origin-destiny displacements for specific movements (house-work, house-school, house-shopping, house-healthcare and house-leisure), all of which being analyzed within the relationship between public transportation and poverty spaces of the city. In order to develop the study, theoretical aspects and themes related to the production of the urban space, to social and spatial segregation, to urban mobility and to transportation were confronted with the collected data referring to the urban population previously selected. One of the research main findings is the crucial role mobility plays in the social differentiation of such people living in Natal and that any policy for the improvement of their living conditions must take mobility issues into account

O processo de envelhecimento da humanidade é um fenômeno mundial e nas últimas décadas a população brasileira tem acompanhado essa tendência. No entanto, este fenômeno somente pode ser considerado como uma real conquista em termos sócios demográficos na medida em que se agregue qualidade aos anos adicionais de vida para a população. Em populações idosas, a incapacidade funcional e os sintomas depressivos tornaram-se importantes conceitos tanto por suas consequências para a saúde pública, quanto pelo impacto na qualidade de vida dessas populações. Este estudo tem como objetivo verificar se há associação entre os sintomas depressivos e o desempenho funcional de idosos comunitários. Foram avaliados 313 idosos de um centro urbano do nordeste brasileiro através das baterias de testes; Center for Epidemiologic Studies Depression CES-D e Short Physical Performance Battery - SPPB; além de variáveis relacionadas ao estado físico, condições crônicas, função cognitiva e características sócio demográficas. Foram utilizadas medidas de correlação e aplicado método de análise multivariada para construir um modelo explicativo da influência da sintomatologia depressiva no desempenho funcional. Os resultados revelaram que as mulheres apresentaram mais sintomas depressivos (p< 0.01) e pior desempenho funcional (p< 0.01) que os homens. Os indivíduos com sintomatologia depressiva apresentaram pior desempenho funcional, especialmente as mulheres. A idade, o sexo feminino, o estado de saúde percebido, o nível de função cognitiva e o Índice de massa corporal foram identificados como fatores associados ao desempenho funcional na amostra estudada. Os resultados deste estudo permitem inferir a relação de associação entre sintomas depressivos e desempenho funcional em uma população de idosos de um centro urbano no nordeste do Brasil. Estes resultados fornecem informações úteis para intervenções terapêuticas adequadas voltadas para a prevenção do declínio na mobilidade em idosos

O objetivo deste trabalho foi determinar a mobilidade do herbicida sulfentrazone em duas classes de solos (Nitossolo Vermelho e Neossolo Quartzarênico), em função de índices pluviométricos crescentes, sendo, portanto, influenciado pelas propriedades químicas e físicas dos solos com diferentes teores de ferro. em tubos de PVC de 10 cm de diâmetro por 50 cm de comprimento, preenchidos com os solos e saturados com água a 65% (p/p), foi aplicado o sulfentrazone (800 g ha-1). Na seqüência, foram simuladas chuvas diárias de 10 mm até atingir os índices pluviométricos de 30, 60 e 90 mm. Os tubos de PVC foram então desmontados - semeando-se Sorghum bicolor nas profundidades correspondentes de 2,5; 7,5; 12,5; 17,5; 22,5; e 30,0 cm da superfície do tubo - e mantidos em casa de vegetação por 15 dias, para avaliação da germinação e do crescimento inicial das plântulas. No final do experimento foram avaliadas as alterações morfofisiológicas que caracterizavam os efeitos tóxicos do produto, além de se medir o comprimento da parte aérea até a última lígula visível e a fitomassa seca das plantas. Quando sob precipitação de 90 mm no Neossolo Quartzarênico, o sulfentrazone formou uma banda de arraste de até 12,5 cm e, no Nitossolo Vermelho, até os 7,5 cm.

Este trabalho objetivou determinar a mobilidade do sulfentrazone em duas classes de solos em função de índices pluviométricos, bem como possíveis influências das propriedades químicas e físicas de Latossolo Vermelho e Chernossolo com diferentes teores de ferro na ação do herbicida. Foram utilizados como recipientes 36 tubos de PVC de 10 cm de diâmetro por 50 cm de comprimento. Os recipientes foram preenchidos com os solos e umedecidos a 65% (p/p) da capacidade de saturação, quando se fez a aplicação do sulfentrazone (800 g ha-1 de i.a.) na área exposta dos solos. Na seqüência, foram simuladas chuvas diárias de 10 mm até atingir o índice pluviométrico desejado (30, 60 e 90 mm), sendo, posteriormente, desmontados seis tubos de cada solo (com e sem aplicação). Foram semeadas cinco sementes de sorgo (Sorghum bicolor) nas profundidades de 2,5; 7,5; 12,5; 17,5; 22,5; e 30,0 cm, mantidas em casa de vegetação por 15 dias para avaliação da germinação e do crescimento inicial. Decorrido esse tempo, foi realizada avaliação de possíveis alterações morfofisiológicas que pudessem ser caracterizadas como efeitos tóxicos do produto e mediu-se o comprimento da parte aérea até a última lígula visível. As partes aéreas foram secas em estufa com circulação forçada de ar (70 ºC por 96 horas), para obtenção de matéria seca. No Chernossolo ocorreu uniformidade da distribuição do produto ao longo do tubo, proporcional à precipitação, e no Latossolo Vermelho o sulfentrazone foi pouco móvel, permanecendo na camada superficial, independentemente da precipitação.

One of the concerns of this century is with the handling and the final destination of urban solid waste (RSU), where depending on the form as they will be made use, they can cause diverse problems, they are of ambient or social order, being able to generate the loss of the quality of life and illnesses to the population, of direct or indirect form. The objective of the present work was to diagnosis the environmental partner situation of the Final Destination of the urban solid residues in the District of Guajiru, city of São Gonçalo do Amarante/RN, standing out the partner-economic situation of the scavengers. The research was carried through in the period of March of 2008 the October of 2009, with a methodology developed through analyzes them of documents made available for the state ambient agency, the Air base of Christmas and managing agencies of the city. For collection of the date, it was used directly application of the questionnaire with 20 existing scavengers in points of destination of residues, evaluation of the old place of final destination through the use of the spread sheet of the IQR (Index of Quality of the Residues), developed for the CETESB, identification of the matter dump and photographic register. For effect of treatment of the data, a descriptive analysis with regard to the answers of the interviewed scavengers was carried through. The acquired date, Scale had been according to tabulated and analyzed in Excel 2003, where they had been generated graphical to observe the behavior of the data. The results show that of the twenty interviewed scavengers, 35% possess age between 20 and 30 years; 75% possess incomplete basic education; 60% inhabit in houses of waal or huts (cardboard or wood); 55% do not make use of system of water supply and system of sanitary exhaustion; with regard to income monthly for scavengers, 35% had presented income between R$ 200,00 and R$300,00 and 20% possess income above of R$ 500,00 for possessing another source of income; 80% of the interviewed ones, use some type of equipment of individual protection; In the year of 2009, confirming what it was informed by the State agency of Environment, during the field visit, we evidence that the city of Is Gonçalo do Amarante, currently, destines its residues in Sanitary landfill of São Region Metropolitan of Natal in the District of Massaranduba in the city of Ceará-Mirim, after some interventions of the State Public prosecution service. However, in the district of Guajiru some diggings still exist that today are used as final destination of RCD' s (Residues of Construction and Demolition) of the cities of Natal and São Gonçalo do Amarante, as well as private dumps that are used by scavengers that deviate the final destination (Sanitary landfill) of the residues of the great generators (supermarkets, shopping Center and hotels), with presence of urubus, generating a new ambient problem for the city and the aeroportuária security. Ahead of this scene, the study it suggests viable alternatives for the elimination of the private dumps and for the social situation of the escavengers, aiming at to improve its quality of life and 10 to minimize the ambient impacts caused by the inadequate destination of the solid waste in the community of Guajiru, São Gonçalo do Amarante/RN, being able to contribute so that the public managers carry through action in the handling and the control of the final destination of the urban solid waste

The objective of this work is to critically analyze the seated mobility adaptive equipment, wheelchair, used by non-ambulatory children/adolescents diagnosed with cerebral palsy of the quadriplegy type with ages in between 0-18 years old in the municipal city of Natal/RN and of other ones in the state of Rio Grande do Norte. This study is characterized as descriptive as it took into consideration the individualized conditions of each child/adolescent and of their home environment, and also evaluates the condition of the used seated mobility devices such as wheelchairs or strollers. Thirty three (33) subjects which had a wheelchair prescribed by a healthcare professional specialist in adaptive equipment within the past 3 years were selected. A questionnaire was applied through a phone with the patient s primary care giver or parents. The results obtained showed that all the equipment being used had an anatomical seat and back and the tilt system mechanism and even though most of the patients required small individual adjustments upon receiving the wheelchair in order to accommodate to the patients characteristics. From the point of view of the caregiver/parents interviewed, 97% described satisfied with the equipment and report assistance with mobility (97%), comfort (82%) and good posture (82%) as the main positive aspects from the equipment. The results also describe the aspects related to the maintenance, time used and activities developed that were reported by the patients. The conclusion therefore is that in order to select the equipment to meet the needs of the consumer it is necessary that: an appropriate wheelchair prescription takes place, the up-to-date knowledge of equipment available in the market, the appropriate use of the resources from the concession programs of the government that purchase equipment and the establishment of link in between the manufacturers, patients and the caregivers
