Defective Interfering Particles of Poliovirus IV. Mechanisms of Enrichment [PDF]
Journal of Virology, 1973 Infection of HeLa cells by mixtures of standard poliovirus and defective, interfering (DI) poliovirus particles leads to a higher ratio of DI particles in the progeny than in the inoculum. The extent of this enrichment could be varied by various manipulations of the co-infected cells.

Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens [PDF]
, 2008 Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for ...

Nutrient enrichment affects the mechanical resistance of aquatic plants [PDF]
Journal of Experimental Botany, 2012 For many plant species, nutrient availability induces important anatomical responses, particularly the production of low-density tissues to the detriment of supporting tissues. Due to the contrasting biomechanical properties of plant tissues, these anatomical responses may induce important modifications in the biomechanical properties of plant organs ...

Mechanisms of speciation and faunal enrichment in Atlantic parrotfishes [PDF]
Molecular Phylogenetics and Evolution, 2006 Relationships based on mtDNA and nDNA sequences were used to assess effects of two major geographic barriers (the >30 myo Atlantic ocean and the approximately 11 myo Amazon-Orinoco outflow) on speciation among Atlantic parrotfishes (Sparisoma and Nicholsina).
