Over the past 20 years, understanding of the functioning of urban ecosystems has increased to the point where fairly sophisticated models of various subsystems have been developed by scientists working for federal, state, and local agencies, often in cooperation with university researchers. Each is designed to collect data and explore a specific urban/environmental system for issues related to ...
Data from Berlin (Germany) show a significant correlation between the increase in the stork population around the city and the increase in deliveries outside city hospitals (out-of-hospital deliveries). However, there is no correlation between deliveries in hospital buildings (clinical deliveries) and the stork population. The decline in the number of pairs of storks in the German state of Lowe...
– The multipath characteristics of the WLL channel were studied over both short and long time periods in urban and sub-urban high-rise and small-house environments. Wideband measurements were performed at the centre frequency of 1.3 GHz with a sliding correlation measurement system using a chip rate of 15 MHz. The receiver was situated at regular cellular base stations, and the transmitter with...
To determine the preliminary effectiveness of breast cancer screening among Chinese females, 1226714 women aged 35-69 years first received clinical breast examinations. Urban women with suspected cancer received mammography followed by breast ultrasound (BUS), while rural suspected women underwent BUS followed by mammography. After one-year follow-up, 223 and 431 breast cancers were detected am...
Urban surface energy fluxes are closely associated with land-cover types (LCTs) and critical biophysical compositions. This study aims to assess the contribution of LCTs, vegetation fractional coverage (VFC) and percentage of impervious surface area (ISA%) to urban surface energy fluxes using remote sensing. An advanced urban surface energy flux algorithm was used to combine satellite imagery a...
This study aims to assess the prevalence of underweight, overweight and obesity among adults in urban Hanoi, Vietnam; and compare these results to previous estimates among adults in urban Ho Chi Minh City. Survey participants were residents in urban Hanoi, Vietnam and aged between 25-74 years. Data from a cross-sectional biomedical survey conducted in 2004 were collected; which included a quest...
Rapid urbanization has made the inner city change quickly with the urban sprawl of the whole city. In China, a mass of urban renewal projects have been carried out for meeting the new need of people’s life. However, the traditional means of total renewal has destroyed the urban heritage seriously, which especially led to the diminishing of historical district space. It is urgent to protect and ...
