or shape and have at least partially overlapping particle size and settling rate (particulate characteristics) distributions the mixture, in which the components are present sortable, is subjected to two dry classification steps in which different particulate characteristics of the particles are decisive....
Litter mixtures often decompose at a different rate than the average of the individual litters, but, so far, the underlying mechanisms are not understood. We propose here an explanation based on a model with two litters. The model describes the carbon and nitrogen mineralisation of the litters....
The two protein families were indistinguishable along the PC2 axis and both are more concentrated in the centre region of PC2. It is reasonable to speculate that proteins with alternating short hydrophobic and hydrophilic segments are less prone to aggregation and are more preferable through evolution...
