Portable Accumulation Chambers (PAC) for Measuring Enteric Methane in Cattle

Breeding has been shown to be a viable solution for reducing methane emissions in ruminants but requires obtaining on-farm measurements of methane. One technology that has successfully been used on-farm to obtain short-term commercial methane measurements in sheep and goats is portable accumulation chambers (PAC).

Accumulation chamber measurements of methane fluxes: application to volcanic-geothermal areas and landfills

Applied Geochemistry, 2003
Direct measurement of present day CH4 diffuse degassing from the soil represents an effective tool to better estimate the degassing rate of individual sources and to calibrate global Earth degassing estimates. While many data exist on CH4 emissions from ecosystems, agricultural soils and landfills, few estimates of CH4 emissions from volcanic ...

Accumulation chamber method and landfill gas diffuse emissions monitoring

2008
A measurement method has been developed and applied in order to measure and help to minimize the impacts of landfills on the atmosphere and to reduce greenhouse gases emissions. The studied method is the accumulation chamber, which resulted suitable for the quantification of non collected emissions of landfill gas (LFG). The measure campaigns have been

Modeling of the nox accumulation kinetics in the combustion chamber of diesel engine

2014
The kinetics modeling of nitrogen oxides accumulation in the combustion chamber of a diesel engine is an important factor in optimizing its operation both at the design stage and in choosing the optimal composition of the fuel for environmental criteria, efficiency and durability.
