Risk assessment of engineered nanomaterials necessitates the need for information on reactivity and persistence of these materials in the environment.
A moderate sedimentary rate was shown to help the persistence of planting materials, which, in turn, benefitted the colonization of S. mariqueter seedlings by vegetative tillering and rhizome growth underground.
The duration of the persistence of the materials was determined, and special attention was given to the reaction of the tissues to the presence of the interposed material.
The need to handle full text imposed related requirements, including ability to handle multiple file formats (Microsoft Word.doc, Adobe Acrobat.pdf, Excel.xls), as well as access to and persistence of supplementary materials.
In field sites, such fibers were found 15 years after last application, highlighting the potential persistence of this material in the soil environment.
We offer a more mundane example below to illustrate the complex selection matrix that influences the persistence of much material culture.
The same asymmetry is exploited in non-denial denials, such as Republican campaign operative Mary Matalin's disingenuous protest "We've never said to the press that Clinton's a philandering, pot-smoking draft-dodger" (see also Giora 2007 on psycholinguistic evidence for the persistence of negated material).
Therefore, persistence of fungal material is correlated with the ability to germinate in host lung tissue.
The persistence of the material in the subretinal space increases the likelihood of the formation of lipofuscin precursors, which are autofluorescent and susceptible to oxidative damage [ 12].
(17) This "islet sealant" application represented the first in vivo analysis of a mussel-inspired adhesive and established the biocompatibility and persistence of the material.
