Microbial co-existence and stable equilibria in a mechanistic model of enteric methane production : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Mathematics at Massey University, Manawatū Campus, New Zealand [PDF]
, 2016 Globally, 14.5% of all anthropogenic greenhouse gases come from ruminants. One of these is methane, which is produced in the rumen of ruminant animals. Feed is degraded by microbes to produce volatile fatty acids (which are absorbed by the animal) and

Does biodiverse moutain grasslands reduce enteric methane emissions?
Plant secondary metabolites are known to mitigate enteric methane emissions. They can be found in biodiverse pasture, rich in fobs, which have been shown to reduce enteric methane (CH4) production in vitro. We set up an in vivo experiment to measure methane (CH4) emission, dairy performances and digestive parameters of 28 grazing dairy cows, allocated ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The d‐band center of Ir in Ir@BNC is synergistically regulated by B and N elements with large electronegativity differences and thus Ir@BNC exhibits eminent performances for both HER and HzOR, requiring −25 and 18 mV to reach 10 mA cm−2 in alkaline conditions. The OHzS device can be powered by DHHPFC and realize hydrogen production at a stable rate (53.

Greenhouse Gas Emission Factor Module: Land Use in Rural New Zealand—Climate Version 1 [PDF]
Several different New Zealand economic models produce measures of rural economic activity that have greenhouse gas implications. For climate change analysis, models need to translate economic activity into greenhouse gas emissions.

Estimating the Marginal Costs of Greenhouse Gas Emissions Abatement using Irish Farm-Level Data [PDF]
Agriculture in Ireland accounts for a higher proportion of greenhouse gas (GHG) emissions than in any other EU member state. Furthermore as part of the EU’s commitment to reduce emissions by 20 percent by 2020, Ireland is one of the few countries who ...

Modeling Greenhouse Gas Emissions on Diversified Farms: The Case of Dairy Sheep Farming in Greece [PDF]
Agricultural activity has been identified as a considerable source of Greenhouse Gas (GHG) emissions. Emissions from ruminant livestock farms are produced particularly due to CH4 emissions from enteric fermentation.

Emissions of organic carbon and methane from petroleum and dairy operations in California's San Joaquin Valley [PDF]
, 2013 Petroleum and dairy operations are prominent sources of gas-phase organic compounds in California's San Joaquin Valley. It is essential to understand the emissions and air quality impacts of these relatively understudied sources, especially for oil/gas ...
