Stoichiometries of remineralisation and denitrification in global biogeochemical ocean models [PDF]
, 2009 Since the seminal paper of Redfield (1934), constant stoichiometric elemental ratios linking biotic carbon and nutrient fluxes are often assumed in marine biogeochemistry, and especially in coupled biogeochemical circulation models, to couple the global ...

, 2020 Organizing Matters demonstrates the interplay between two distinct logics of labour’s collective action: on the one hand, workers coming together, usually at their place of work, entrusting the union to represent their interests and, on the other hand, social bargaining in which the trade union constructs labour’s interests from the top down.

Organic Matter in Cosmic Dust [PDF]
Elements, 2016 Organics are observed to be a significant component of cosmic dust in nearly all environments were dust is observed. In many cases only remote telescope observations of these materials are obtainable and our knowledge of the nature of these materials is very basic. However, it is possible to obtain actual samples of extraterrestrial dust in the Earth's

A divergent heritage for complex organics in Isheyevo lithic clasts [PDF]
, 2017 Primitive meteorites are samples of asteroidal bodies that contain a high proportion of chemically complex organic matter (COM) including prebiotic molecules such as amino acids, which are thought to have been delivered to Earth via impacts during the ...

Long term trend of chemical oxygen demand in Saroma-ko Lagoon, Japan; possible effects of climatic warming [PDF]
, 2008 A trend of shortening duration of ice coverage has been reported in many rivers, ponds and lakes around the world due to climatic warming. The shortening will have much influence on organic production due to the greater supply of light intensity and ...
