The rapid rise in asthma over the past three decades in Western societies has been attributed to numerous diverse factors, including increased awareness of the disease, altered lifestyle and activity patterns, and ill-defined changes in environmental exposures.
Differences in virulence have been attributed to numerous factors including host genetics, management practices, and virus strain heterogeneity [ 9- 16].
The sudden and rampant resurgence of C. lectularius has been attributed to numerous factors including frequent international travel, narrower pest management practices, and insecticide resistance.
The toxicity of developmental ethanol exposure has been attributed to numerous mechanisms, including ethanol metabolism and related oxidative stress, neuronal cell loss, and inhibition of growth factors and/or their signal transduction pathways.
This flexibility has been attributed to numerous factors including differences in foraging habitat [ 49, 50], prey size [ 51], variation in body size [ 52], age [ 53] and sexual dimorphism [ 54].
The increasing global popularity of day case surgery and consequently ambulatory anaesthesia have been attributed to numerous advantages such as reduction in hospital costs (e.g. hospitalization and bed space) [ 22], shorter waiting lists, patient's ease and less disruption to daily life activities, quick recovery and reduced postoperative demands like analgesics [ 23].
Their success can be attributed to numerous advantageous design features.
That may explain the consistent look and feel of the films, even though they were attributed to numerous directors.
The enhanced siliconizing kinetics is attributed to numerous grain boundaries (GBs) in the nanostructured surface and deformed layer.
These spatial differences in membership could, however, primarily be attributed to numerous bacterial species that were either very low abundant or absent, as they did not contribute significantly to the dissimilarity in the overall microbial communities.
However, it is difficult to implement many energy efficiency improvements in urban rail systems which can be attributed to numerous, often interrelating, factors.
