Abstract The objective of this research project was to compare two stormwater management strategies within a nutrient-sensitive watershed: impervious cover limits versus pollutant-load regulations. A case study was conducted in the nutrient-sensitive Falls Lake watershed in North Carolina, USA, where a commercial fitness complex was constructed in a zone previously restricted to low-density housing. The Falls Lake watershed has a stormwater regulation that limits total nitrogen and total phosphorus export loads to 2.47 kg/ha/yr and 0.37 kg/ha/yr, respectively. Hydrology and water quality were monitored pre- and post-development to quantify changes to stormwater volumes, pollutant concentrations, and annual export loading rates. On-site stormwater control measures (SCMs) reduced nutrient export loading rates below the regulatory standard. However, increased stormwater volumes and nutrient export loading rates were observed from pervious surfaces that were disturbed during construction (total nitrogen increased from 2.06 to 4.24 kg/ha/yr, total phosphorus increased from 0.41 to 0.73 kg/ha/yr). Results from this case study suggest that (1) impervious cover limits do not adequately account for a parcel's nutrient export loads and (2) SCMs that reduce volume and treat pollutants can reduce nutrient export loads below regulatory levels in the Falls Lake watershed.

This paper describes a case study on a new alternative drainage system for urban stormwater management, the so-called “Sandsli-system”. The aim of this study is to evaluate the Sandsli system and the effects of the solution on ground water conditions. The study is carried out in the Sandsli research catchment in Bergen, Norway. The idea behind the “Sandsli-system is not to mix the polluted and the clean stormwater combined with a source control for both stormwater quantity and quality. The clean stormwater is percolated as quickly as possible, while the polluted stormwater is collected and conducted to an appropriate site for disposal or treatment. The Sandsli-system was developed as an alternative drainage system to the conventional drainage system. The system has been functioning satisfactorily since 1981 to date. The advantages of the use of the Sandsli-system is highlighted i.e. recharging the stormwater to the ground water. The Sandsli-system is appropriate to locations with climate and geology similar to that found in the coastal part of Norway

Research on neighborhoods is dominated by a focus on the social aspects of neighborhood life. The ability of neighborhoods to function as service providers is a critical and understudied aspect of neighborhood research. This paper offers a methodological contribution of the analysis of neighborhoods as service providers. Provision of services is defined in terms of accessibility, or the spatial proximities between residents and the facilities. Because the focus is on neighborhoods, access is defined on the basis of the pedestrian rather than the automobile. In addition, the needs of the neighborhood population are considered. A case study of Portland, Oregon, is used to demonstrate how an evaluation of pedestrian access could be conducted at the neighborhood scale.

<p class="zhengwen">Due to physical and mental disability, children tend to withdraw themselves from society especially if their parents abandon them, and if society fail to establish a suitable relationship with these children, their presence will uproot from society. In this paper, we deals with the case Rofaydeh Welfare Services Complex in Iran in the he city of Tehran where 60 disabled, mentally or physically disabled children are taken care of, some of them were also orphans. The aim of the article is to provide an environment which is conducive to more relationship and interaction of these children with members of society with regard to their lack of caretaker and family, as well as protecting the primacy of the children's living spaces as their home.</p><p>The research methodology included library and field methods; thus, suitable strategies were developed to achieve the goal of this paper. The research indicates that designing the complex as a house in the middle of the neighborhood park allows for children's presence in the society among the people and close interaction with people through being positioned in a neighborhood park, as well as providing the presence of the children in a space similar to a house which is every child's wish. On neighborhood scale, the park protects the children from social damages so that they feel sense of intimacy working between them and people.</p>

Introduction: This study is justified since very little is known of the relationship between Leishmaniasis and the spatial transformation process. In the past, the municipality of Teodoro Sampaio has spread ACL and recently cases of visceral Leishmaniasis have been found in dogs in the urban area, making the municipality a likely area for the convergence of both manifestations of the disease. The overall aim is to relate recent spatial transformations with the pattern of spatial distribution of the infection’s vectors and hosts, keeping in mind the integrated geographic distribution of ACL and AVL.  Methods:  The study has two levels of aggregation: (a) a population-based case study of the municipality of Teodoro Sampaio, Pontal do Paranapanema, in the state of São Paulo, designed to be quantitative, descriptive and cross-sectional, and (b) population-based across the municipalities of São Paulo state, designed to be retrospective, quantitative, observational and descriptive. The choice of two approaches to the study is justified by a consideration of the articulations which enable the formation of production circuits for Leishmaniasis in the region. The gathering of data for the Teodoro Sampaio case study underwent two phases: field study and by means of secondary official data sources. Data concerning the state of São Paulo comes from secondary sources.  Conclusion: As it is a focal disease, the data presented allows us to infer that AVL spreads from Sector 1 of the urban area to Sector 3, because the vector relevant to transmission is within the former. The ACL pattern in Teodoro Sampaio is thought to be based in the woodlands surrounding the urban area, in general terms, based in the Parque Estadual do Morro do Diabo (PEMD), the edge of which is five kilometres from the centre of the district. Exchanges take place between the urban area of the municipality, the PEMD, the settlement of Ribeirão Bonito, which forms part of the transect making up the geosystem of Teodoro Sampaio, and Pontal do Paranapanema. Human intervention can be seen as the main agent in promoting these exchanges between environments due to the transit of people between subgeosystems and the interrelationship with other municipalities encouraging the spread of the disease. The only municipalities to be among those with a high incidence of AVL are Araçatuba and Presidente Prudente, although the number of cases is growing and becoming more concentrated. The state presents a circumscribed hub of AVL cases in the region of Campinas and Piracicaba, and another in Pontal do Paranapanema. This interaction borders on Mato Grosso do Sul, giving rise to the main circuit AVL instances of the Southeast. ACL has a hub at Itapetininga, which is next to Vale do Paraiba Paulista, also leading to interactions across the border with the state of Rio de Janeiro and its principal circumscribed centres of transmission of ACL. This will be Brazil’s next ACL production circuit. It was possible to identify areas in the state of São Paulo particularly vulnerable to Leishmaniasis with particular distributions for each of the two types of the disease, sometimes existing together. Outbreaks of canine VL do not depend on distribution rules on a small scale, although the effect of many outbreaks together clarifies a spatial pattern, as seen in the state of São Paulo. Patterns of transmission of Leishmaniasis are established in the state of São Paulo and the data analyzed helps to verify these patterns.
