Particle pollution represents a mix of tiny solid and liquid particles that are suspended in the air, some of which are so small that they are able to pass through the lung tissue and into the blood stream, narrowing arteries and causing systemic inflammation.
To the south and east are the foothills of Appalachia, with winding country roads that, when crossing a stream, narrow to a single lane.
Ice streams, narrow zones of fast flow in ice sheets that are otherwise dominated by slow sheet flow, are also common features of Quaternary ice sheets.
The male, about 90 cm (35 inches) long, with streaming, narrow, cross-barred tail, has a brown back and coppery breast, purplish-green neck, and two small ear tufts; his entire body is speckled and barred.
Streams (narrow watersheds) contributed 5% (6 m3 s−1) of the riverine volume flux, but contributed 15% (0.50 mol s−1) of the riverine DIN flux owing to high DIN concentrations in the steam water.
As the stream of recovered material narrows every day, NASA scientists fine-tune a map of the likely areas where more debris could be found.
When village competed against village, kicking, throwing, and carrying a wooden or leather ball (or inflated animal bladder) across fields and over streams, through narrow gateways and narrower streets, everyone was involved men and women, adults and children, rich and poor, laity and clergy.
The problem lies with the jet stream, a narrow band of strong winds that sweeps round the planet between the tropics and the Arctic.
The divider, in fact, is a stream so narrow that the two sides could toss a football back and forth, if they wanted.
He would draw on two areas: the rockery designed by Joseph Paxton, the Victorian engineer-cum-landscape architect who shaped Chatsworth's huge vistas, and the "trout stream", a narrow rivulet of water running in soft loops through the top of the garden.
