Rats trapped from 14 locations in Baltimore, Maryland, were shown to have antibody to Hantavirus. Antibody prevalence rates were higher in residential locations than in parks. Infected rats were obtained continuously over a six-year period from 1980-1985 at five locations, indicating the enzootic nature of this infection in urban rats in the United States. Prevalence of antibody and geometric m...

To monitor water quality continuously over the entire sewer network is important for efficient management of the system. However, it is practically impossible to implement continuous water quality monitoring of all junctions of a sewer system due to budget constraints. Therefore, water quality monitoring locations must be selected as those points which are the most representative of the dataset...

The aim of this study was to assess associations between the built environment and social environment and excess weight in an urban population. Participants were selected from the Surveillance System for Risk Factors for Chronic Diseases (VIGITEL). The study used data from the city of Belo Horizonte, Minas Gerais State, Brazil. A total of 3,425 interviews from the years 2008 and 2009 were used....

OBJECTIVE Safety net health care centers in the US serve vulnerable and underinsured females. The primary aim of this work was to determine if HPV4 dosing compliance differs between females who receive doses at rural vs. urban core safety net health care locations. METHODS Females exclusively receiving health care in the Truman Medical Center (TMC) safety net system at the urban core and rura...

A number of studies have compared general medical practices in rural locations with those in urban locations. Some of these studies have concentrated on the reasons why a GP might choose to work in a rural or urban setting. Others have examined the type of work required to be undertaken by medical professionals. Increasing use of information and communications technology (ICT) in medical practi...

Restriction on the supply of new urban land is commonly thought to raise the value of existing urban land. Our paper questions this view. We develop a tractable production-externalitybased circular city model in which firms and workers choose locations and intensity of land use. Consistent with evidence, the model implies exponentially decaying density and price gradients. For plausible paramet...

the aim of this study was to isolate and identify airborne fungi from locations in babol city, babolkenar forest and a beach on the caspian sea (all in north part of iran) in spring and summer. of 126 samples collected, the most clinically important isolated fungi were mucor spp. (18.6%) in the forest, alternaria spp. (13.4%) at the beach; and cladophialophora spp. (15.8%), mucor spp. (11.7%) a...
