Gaseous exchange and electrical activity of skeletal muscle were studied in white rats at rest. The rectal temperature varied between 38.5°–40° and 18–11°. It was shown that when the body temperature was high, gaseous exchange was minimal and there was no electrical activity in the muscles...
Furthermore, the generation of O3 is also linked to either stratosphere−troposphere exchange processes or downwind transport from the source. In urban regions, which characteristically have high NOx concentrations, the generation of O3 is VOC-limited, while in rural areas, O3 generation is mostly...
Indoor and outdoor concentrations of HCl, HNO, HCOOH and CHCOOH were determined in two medieval churches in Cyprus, during July 2003 and March 2004. The high air exchange rate through the open windows and doors led to lower indoor, compared to outdoor, acid concentrations in July 2003. ...
long lifetime of Hg(0) leads to Hg deposition far from its emission sources to remote ecosystems, including the open oceans and polar regions. In aquatic ecosystems, Hg(II) is methylated and may be biomagnified up the food chain to levels that induce toxic effects in wildlife and humans8....

Continuous versus single bolus enteral nutrition: comparison of energy metabolism in humans Continuous respiratory exchange measurements were performed on five women and five men for 1 h before and 6 h after the administration of a milkshake (53% ... CA Nacht,Y, Schutz,O, Vernet,... - 《Am...
Formaldehyde is a ubiquitous carcinogenic indoor pollutant. The treatment of formaldehyde has attracted increasing social attention. Over the past few deca
(minutes to hours), thus a faster-response sensor would improve characterization of surface-atmosphere exchange processes and atmospheric Hg dynamics.;The goal of this thesis work was to develop a new, field-deployable sensor for high time resolution measurements of GEM in ambient air using pulsed...
The exchange of the lubrication oil took one day and consisted of full draining of the used oil over night, four flushing cycles, exchange of oil filters, and a running-in program on different engine loads with MGO for 2 h. The order of fuel tests was from light to heavy. Thereby, ...
