Frey, B., Niklaus, P. A., Kremer, J., Luscher, P. & Zimmermann, S. Heavy machinery traffic impacts methane emission, abundance of methanogens and community structure in oxic forest soils.
Lutetium-177 has a physical half-life of approximately 6.7 days and emits β− particles (E β of 497, 384, and 176 keV) and also γ photons with low energy (E γ of 113 and 208 keV with low emission abundance of 6 and 11%, respectively) [37].
We infer from the absolute intensity of the nocturnal D-doublet emission, the abundance of free Na and other relevant information that there is very little possibility of an alternative to Chapman's theory1 that the excited Na atoms involved are released by NaO O collisions.
The effects of replacing 35% of cereals-based concentrate with feed blocks (FB) containing waste fruits of tomato, cucumber, or barley grain in diets for lactating goats on nutrient utilization, ruminal fermentation, microbial N flow to the duodenum, milk yield and quality, methane emissions, and abundances of total bacteria and methanogens were studied.
Stronger associations between methane emissions and abundance of H2-producing bacteria in sheep have been reported by Kittelmann et al. [ 49], who distinguished three 'ruminotypes'ruminotypes
We obtain four temperatures: 1.6, 5.2, 8.2, and ≳20 MK, emission measures and abundances.

"Abundances, emissions, and loss processes of the long-lived and potent greenhouse gas octafluorooxolane (octafluorotetrahydrofuran, c-C4F8O) in the atmosphere". 19, no.
A composite dust grain model which simultaneously explains the observed interstellar extinction, polarization, IR emission and the abundance constraints, is required.
Expecially in air masses polluted by anthropogenic emissions (i.e., autovehicular traffic and/or industrial emission), the NMHC abundance causes a rising of PAN mixing ratios sometime up to several ppbv [17].
A recent study showed rapidly increasing atmospheric abundances and emissions.
