Loose particles on impervious surfaces are an important carrier to transfer pesticides into residential runoff water and subsequently contribute to contamination of urban streams and estuaries by urban-use pesticides. However, data regarding levels of pesticide contamination in the runoff-transferable dusts are scarce and their runoff potential and toxicity impacts to urban watersheds still rem...

The tools and technology that are currently used to analyze chemical compound structures identify polymer types in microplastics not well-calibrated for environmentally weathered microplastics. Microplastics have been degraded by environmental weathering factors can offer less analytic certainty than samples of exposed processes. Machine learning techniques allow us better calibrate the researc...

This article presents a case study of the London suburb Chipping Barnet to show how spatial-morphological approach tangible heritage challenges its archetypal image as an affluent commuter by highlighting resilience generative patterning social space that has weathered successive phases change. We argue enduring definition local centre explains it been possible preserve something less tangible—...

The use of wood-derived fillers by the thermoplastic industry has been growing, fueled in part by the use of wood-fiber– thermoplastic composites by the construction industry. As a result, the durability of wood-fiber–thermoplastic composites after ultraviolet exposure has become a concern. Samples of 100% high-density polyethylene (HDPE) and HDPE filled with 50% woodflour (WF) were weathered i...

For true 3D navigation applications that combine terrain data, city models, landmarks, and other 3D geo data, also a real 3D street network is necessary for the route calculations. In this paper we describe how such a network can be derived automatically using detailed digital terrain models. Furthermore a method is described how the terrain model can be enhanced by integrating the roads direct...

BACKGROUND Long-term exposure to pollution can lead to an increase in the rate of decline of lung function, especially in older individuals and in those with chronic obstructive pulmonary disease (COPD), whereas shorter-term exposure at higher pollution levels has been implicated in causing excess deaths from ischaemic heart disease and exacerbations of COPD. We aimed to assess the effects on r...
