In total, seventeen young adults with normal hearing were tested in a large anechoic chamber in two experiments.
Methods: Twenty-two participants were exposed to CO2 at 600, 1,000, and 2,500 ppm in an office-like chamber, in six groups.
Inhale any remaining smoke in the chamber in one big breath.
Stay home and dream about the beach at Waikiki, or go hear the Emerson String Quartet play Brahms chamber music in three different minor keys.
Mr. Gilbert conducted a chamber orchestra in three premieres, each prefaced by a lively onstage discussion between the composer and the WNYC radio host John Schaefer.
In 2008, the Republicans controlled both chambers in fourteen states; today, they control both chambers in thirty states.
Democrats acknowledge that they will be fighting to preserve their slim majorities in at least 10 chambers — including state senates in New York, New Hampshire and Nevada — but say that they see opportunities to gain control of chambers in four other states.
The emissions of N2O by soils were measured using static chambers in two drained and two undrained cereal plots over two growing seasons.
Nitrous oxide and CH4 emissions were measured using static chambers in four stormwater detention basins – two fast-draining or 'dry' basins and two slow-draining or 'wet' basins.
Production of CH4 was measured for four d in open-circuit respiration chambers in four periods during lactation: at 48, 125, 164, and 212 d in milk (DIM), and feed intake and milk yield were recorded at the same time.
Simultaneously, monthly sampling of gas exchange was conducted using non-steady state chambers in four distinct land-cover types in the wetland: open water, emergent vegetation (Typha spp ., floating vegetation (Nelumbo spp).
