At the same time, however, it is a complex structure, the variability of which makes it difficult to determine the destination points that underlie effective prevention related to the treatment of periodontal disease.> Interactions between microorganisms colonizing the oral cavity are consecutive major factors affecting the development of biofilm [ 25, 63, 64].
Design for human safety is a complex issue because of the variability of human activities, machines and their environment as well as the variability of possible interactions between these components.
Natural variation among a population of individuals is likely to arise from a complex interplay of genetic variability, such as single nucleotide polymorphisms (Borevitz et al. 2007; Clark et al. 2007; Nordborg and Weigel 2008) and gene CNV (Sebat et al. 2004; Conrad et al. 2006; Mileyko et al. 2008; Springer et al. 2009).
The complex natural variability of the rainfall-driven streamflow events introduces a water resources management challenge for the region.
This suggests complex temporal variability of the background neutral wind.
Although the change mechanisms of reservoir parameters (porosity, permeability, and relative permeability curve included) are complex, the variability of these parameters has some internal relation with each other.
The dataset presented here contributes with new data to better understand the complex genetic variability of the Y chromosome in the Iberian Peninsula, that can be applied in Forensic Genetics.
However, in comparison with metal, damage mechanisms are complex and variability of the mechanical properties due to anisotropy, heterogeneity and defects (due to materials but also processing technologies) more important.
VOCs pollution is a complex issue involving a wide variability of pollutants that threatens human health and environment.
Reproduction is the highest priority of all living things, and involves a complex combination of processes whose variability between species has long puzzled evolutionary biologists.
