These are attributed to cumulative matrix residue on the fibre surface after reclamation and subsequently increased fibre-matrix adhesion.
The rapid appearance (over evolutionary time) of the cognitive skills and complex inventions of modern humans has been attributed to "cumulative cultural evolution" (CCE), the accumulation of knowledge and skills over generations.
The higher death rate may be attributed to the cumulative effects of renal papillary necrosis and resultant hyposthenuria [29].
The enhanced activity of the new catalyst can be attributed to the cumulative effects of individual factors involved in the catalyst preparation.

[16] found an equal ratio for the vertical displacement of Me and Me′ (60.9 and 60.4%, respectively); the ratios, however, are smaller compared to the present study which may be attributed to the cumulative effect of the different methods of maxillary impaction used in their sample.
Lack of cell proliferation may be attributed to the cumulative time required to remove the cells from the culture surface to put them into suspension, the shear forces exerted on the cells by the FACS machine, and a lack of paracrine signalling required to stimulate cell survival and proliferation.
Since subjects in the current experiment self-administered nearly 600 mg/kg of cocaine over three weeks and the aforementioned study utilizing cocaine involved approximately 400 mg/kg of experimenter-administered cocaine [9], the finding that SD-induced responding did not become habitual cannot be attributed to insufficient cumulative drug exposure.
These findings support those of previous studies, and can be attributed to the cumulative effect of oral problems as children grow.
A negative impact of longer time after transplantation on the stability of graft function can be attributed to larger cumulative burden of injury with increasing time [ 41] and to the effect of transplant era.
According to the "stress and vulnerability" model [ 29] and the "minority stress" model [ 30], these disparities in health among sexual minorities may be attributed to their cumulative exposure to harassment, maltreatment, discrimination, and victimization stemming from a hostile and homophobic culture.
