It is important to understand the differences between emissions from standard laboratory testing cycles and those from actual on-road driving conditions, especially for solid particle number (SPN) emissions now being regulated in Europe. This study compared particle mass and SPN emissions from a heavy-duty diesel vehicle operating over the urban dynamometer driving schedule (UDDS) and actual on...

For the past 10 years, I have been working as an electrical engineer for Helixx, a recently established car-manufacturing company, on hybrid electric vehicles. The current project is a P2 hybrid, an expansion on the power-split hybrid model that could “provide 95 percent of the fuel efficiency benefits of an expensive two-motor system, like the one in the Toyota Prius, [a power-split hybrid], b...

BACKGROUND Strong community linkages are essential to a health care organization's overall preparedness for emergencies. OBJECTIVE To assess community emergency preparedness linkages among hospitals, public health officials, and first responders and to investigate the influence of community hazards, previous preparation for an event requiring national security oversight, and experience respon...

of medicine, changed beyond recognition during these 100 years. As with all communities, the residents of Coalbrookdale needed doctors. The story explores the evolution of the discipline that we now recognise as general practice but which started from humble beginnings with apothecaries selling medicines to treat undiagnosed ailments. Their medical education initially involved an apprenticeship...

Pandemic (H1N1) 2009 influenza has generated many controversies in Australia around case definitions, laboratory diagnosis, case management, medical logistics and travel restrictions. Our experience as clinical advisers in the Victorian Department of Human Services Emergency Operations Centre suggests the following: Case definitions may change frequently, and will tend to become more clinically...

In the process of hardware optimization, physical queries requiring laboratory experiments are often necessary. This is similar to optimization using software where queries are made to a computer model. In both the laboratory optimization and optimization using computer models, queries come at a cost: laboratory time or computer time. Finding efficient searches using a small number of queries o...
