For more information about frailty models, the process of selection and how they relate to narrowing mortality differentials at old ages, see online supplementary appendix A. In the age-cohort models the introduction of unobserved frailty affected the coefficient for the macroregion of birth significantly.
The shoe sole geometrical design parameters are believed to be important factors affecting the coefficient of friction (COF) between the shoe/floor interface.
According to Dr. Shaw's interpretation of the experiments, it is the mean temperature of the system which affects the coefficient of attraction, so that in the case of extremely unequal masses it is the temperature of the larger mass only which counts.
The ratio of the crest height of side weir to length of the side weir, ratio of width of the main cannel to length of side weir and ratio of the upstream depth in the channel to length of side weir also affect the coefficient of discharge.
Using the orthogonal design based twist compression test in the temperature range of 25 300 °C, the significant factors affecting the coefficient of friction (CoF) and the influencing rules in CP-3 titanium sheet warm forming are clarified and discussed by changing tribological conditions such as tool material, lubrication, temperature and normal pressure.
Paternal smoking during childhood was associated with lower z-score of height-for-age only at preschool age, but when included at multivariable models not remained associated (p = 0.68) and did not affect the coefficient of association between maternal smoking and growth.
Further, the addition of this variable to the models did not significantly affect the coefficients of Medicaid intensity and SES index.
Adjusting for exposure to environmental tobacco smoke and alcohol and caffeine use during pregnancy also did not affect the coefficients of interest.
Assuming that ecological dynamics (i.e., changes in species density) are much more rapid than evolutionary changes (i.e., genetic changes affecting the coefficients of inter-species fitness dependencies) [ 91], most evolution occurs whilst ecological dynamics are at or near equilibrium, as modelled here.
Further analysis demonstrates that survey design choices affect the coefficient estimates of some determinants of child labor in a child labor supply equation.
