STUDY OBJECTIVES To locate geographical sources of engine exhaust emissions in Great Britain and to link them with the birth addresses of children dying from cancer. To estimate the cancer initiating roles of nearby roads and railways and to measure effective ranges. DESIGN Birth and death addresses of all children born between 1955 and 1980 in Great Britain, and dying from leukaemia or other...

The small and simple gaseous molecule ethylene (C2H4) is usually associated with ripening and senescence events in plants. Its effects have been known for ages (literally), and in the last century there have been some major breakthroughs in ethylene biology. These breakthroughs include the discovery that the molecule that hastened the ripening of fruits and caused growth distortions in plants w...

This dissertation is in the area of Computer-Aided Design (CAD) of digital Integrated Circuits (ICs). Today’s digital ICs, such as microprocessors, memories, digital signal processors (DSPs), etc., range from a few thousands to billions of logic gates, flip-flops, and other components, packed in a few millimeters of area. The creation of such highly complex systems would not be possible without...

BACKGROUND AND PURPOSE Air pollution is associated with stroke, and road traffic is a major source of outdoor air pollution. Using proximity to roads as a proxy for exposure to road traffic pollution, we examined the hypothesis that living near main roads increases the risk of stroke mortality. METHODS We used a small-area ecological study design based on 113 465 census enumeration districts ...
