Furfural and its biochar improve the general properties of a saline soil
Organic materials saline soil the physical and chemical properties low fertility biochar
2015/1/6
Organic materials (e.g., furfural residue) are generally believed to improve the physical and chemical properties of saline soils with low fertility. Recently, biochar has been received more attention...
GENERAL-RELATIVITY AS AN EFFECTIVE-FIELD THEORY - THE LEADING QUANTUM CORRECTIONS
Effective gravity quantum field theory natural separation low energy quantum effects high energy massless particles
2014/12/23
I describe the treatment of gravity as a quantum effective field theory. This allows a natural separation of the (known) low energy quantum effects from the (unknown) high energy contributions. Within...
Power counting of loop diagrams in general relativity
Cyclic graph the general theory of relativity energy expansion quantum effects physical power calculation
2014/12/23
A class of loop diagrams in general relativity appears to have a behavior which would upset the utility of the energy expansion for quantum effects. We show through the study of specific diagrams that...
The Quantum Theory of General Relativity at Low Energies
Quantum field theory low energy quantum the interaction energy general relativity low energy
2014/12/23
In quantum field theory there is now a well developed technique, effective field theory, which allows one to obtain low energy quantum predictions in “non-renormalizable” theories, using only the degr...
Evaluation of North Eurasian snow-off dates in the ECHAM5.4 atmospheric general circulation model

This paper explores the feasibility of an experimentation strategy for investigating sensitivities in fast components of atmospheric general circulation models.
A system of conservative regridding for ice–atmosphere coupling in a General Circulation Model (GCM)
conservative regridding ice–atmosphere coupling
2014/12/18
The method of elevation classes, in which the ice
surface model is run at multiple elevations within each grid
cell, has proven to be a useful way for a low-resolution atmosphere inside a general ci...
The Finite Element Sea Ice-Ocean Model (FESOM) v.1.4: formulation of an ocean general circulation model
Finite element model of sea Ice - Ocean global Ocean circulation patterns climate sensitivity experiments
2014/12/18
The Finite Element Sea Ice-Ocean Model (FESOM) is the first global ocean general circulation model based on unstructured-mesh methods that has been developed for the purpose of climate research. The a...
Development of a parameterization of black carbon aging for use in general circulation models
parameterization of black carbon aging general circulation models
2014/12/16
A parameterization of black carbon (BC) aging in the atmosphere is developed for use in general circulation models (GCMs) that separately treat hydrophobic BC and hydrophilic BC modes but do not expli...
